Description

The invention relates to a puck system according to the preamble of claim 1 and a production method for a puck from such a puck system according to the preamble of claim 9. In particular, the conveyor system can be part of a production plant, for example a filling plant.

A puck, also called puck handling, for a conveyor system is a product carrier. Chain conveyors with puck handling are used when small, fragile or unstable products have to be transported and handled. This is the case, for example, when filling containers with cosmetic products or perfumery. For this purpose, the container is stably fastened as conveyed goods on a puck, which is adapted to a conveying device such as a chain conveyor, so that it can be safely transported through the production system, in this case a filling system, by means of the chain conveyor. The puck prevents the conveyed item from falling over during transport or deviating from its predetermined position in any other way. The pucks thus enable precise and stable product transport and thus a high level of process reliability in the production plant.

The shape of the puck is adapted to the conveyor system used. As a result, the conveyor system can transport the puck with the goods to be conveyed on it in an exactly predetermined position. By adapting the puck to the goods for which it is intended, goods of almost any shape can be conveyed through the conveyor system. The precise position of the conveyed item in the puck and the fixed predetermined position of the puck on the conveying means means that the relative position of the conveyed item in the production system is fixed at all times. In other words, the pucks represent the interface between the conveyor system and the goods to be conveyed.

If the design of the material to be conveyed on the pucks changes, only the pucks have to be exchanged to adapt the conveying system. This means that if the conveyed goods processed on a production system are changed over, all pucks of the conveying system must be purchased. Since a large number of pucks are usually in use at the same time for the operation of a conveyor system of a production plant, the procurement of new pucks represents a considerable cost and time factor. Pucks are typically milled from plastic blocks. This production method generates large amounts of waste. The number of pucks required is considerable, but again so small compared to bulk products that their production is quite expensive. The number of pucks usually required is too low for inexpensive mass production, for example by injection molding. For a cost-effective production with a process in which universally applicable tools are used, such as milling a solid plastic block, setting up the machine for the production of a new type of puck is quite complex and time-consuming, so that in this case, too, there are high unit costs surrender. Therefore, efforts are being made to reduce the cost of changing the pucks.

The US patent U.S. 3,090,478 A for example, proposes a concept in which the pucks have a two-part structure. A plastic insert, which is adapted to containers of different sizes, is clamped into an outer metal sleeve. The sleeve and the plastic insert are rotationally symmetrical. This solution has the advantage that only the insert and not the entire puck have to be exchanged in order to adapt the conveyor system to containers of different sizes. However, the solution also has disadvantages. The design of the connection between the two components of the pucks does not allow a defined alignment of the goods received in the pucks around the vertical axis by the conveyor system, since the insert is not clamped into the metal sleeve in a defined, but rather in a random angular orientation around the vertical axis . In addition, when the insert is manufactured from plastic, there is still the problem of the series size, which is unfavorable for plastic parts.

The pamphlet US 2012/0024673 A1 shows a puck, in the shell-shaped body of which a heavy potting compound can be locked to increase weight. The pamphlet WO 2017/157689 A1 shows, however, a generic puck system. Further aspects of such puck systems are given in the publications EP 2 799 884 A1 , EP 3 211 427 A1 and EP 3 172 575 A1 described.

The puck for a conveyor system has a base body which is adapted to the conveyor system and which has an insert which can be inserted into the base body. The insert has a receptacle which is adapted to the shape of the material to be conveyed.

The insert is fastened in a predetermined orientation and releasably in the base body by means of at least one form-fitting connecting element.

The base body is adapted to the conveyor system in such a way that areas of the outer contour of the base body are designed in such a way that the conveying means of the conveyor system cooperate with the puck in order to convey the puck in a predetermined position through the conveyor system. The puck also has an insert. The receptacle for the conveyed goods, which is adapted to the conveyed goods, is part of the operation.

It is provided that the insert is fastened in a predetermined orientation in the base body by means of at least one form-fitting connecting element. The attachment of the insert by means of the form-fitting connecting element in the base body makes it possible to fasten the insert in exactly a defined angular position around the vertical axis in the base body. This enables the conveyed material to be positioned in a predetermined position by the conveyor system. In addition, to adapt the pucks to a conveyed item, only the inserts of the pucks have to be adapted to the conveyed item. A positionally correct and releasable connection between the insert and the base body is achieved by means of a form-fitting connecting element. The inserts can thus be easily removed from the base body and replaced with new inserts. In particular, it is also possible to reinsert the inserts in the base body at a later point in time, for example if the conveyance of certain products is required repeatedly, but at time intervals with intermittent use of the conveying system for other products.

The connecting element can be, for example, a spring catch. Such a spring catch is a connecting element whose function is based on the fact that a region of the insert and / or the base body experiences a temporary elastic deformation when the insert is inserted into the base body, in order to enable it to engage in complementary snap-in receptacles provided on the insert and base body. to enable. In order to separate the insert and the base body from one another again, the corresponding areas of the insert and / or base body are again temporarily elastically deformed in order to disengage the spring catches and latching receptacles. In this way, a form-fitting connection between the insert and the puck can be established in a simple manner, which in particular enables the inserts of the pucks to be changed quickly. Since the receptacle for the conveyed goods is located in the base body in a predetermined orientation, it is also possible to ensure that the conveyed goods received therein are handled in the conveyor system in a precise position. However, other connecting elements are also possible, such as short thread sections in the base body, which interact with at least one complementary thread turn or another engagement body on the insert. A Bayonnet lock can also be used as a connecting element.

The puck can in particular be a puck for receiving a container for a liquid. In this case, the conveyor system can be part of a filling system. In such a case it is advantageous to use the pucks, e.g. for conveying perfume bottles. Perfume bottles, so-called flacons, are often decisive for the customer's purchase and their shape is very complex and unconventional. Different perfumes almost inevitably have bottles that differ greatly from one another, so that the problems described above arise when switching production between two different perfumes from the same manufacturer. Fragrances with any fragrance concentration are referred to here as perfumes. The same problem is faced by manufacturers of cosmetics in different containers.

In practice, the base body can be an injection-molded part made of plastic. The base body can be designed in the same way for a large number of conveyor systems, so that it can be produced in large numbers. Plastic injection molding is particularly suitable for this. The insert can also be a plastic injection molded part. Such a manufacturing method is particularly worthwhile when a large number of identical inserts is required. Compared to massive milled pucks, the amount of material in the puck with the base body and insert as a plastic injection-molded part is reduced by around 40% and the amount of waste generated is significantly lower with injection molding than with milling.

In practice, the base body can be a hollow body with a non-circular interior and the insert has at least one non-circular external cross-section which, when fastened, fits into the non-circular interior with little play.

Furthermore, in practice, the insert can be a plastic part with honeycomb-shaped walls and the receptacle can be milled into the insert. In other words, very light inserts, preferably made of plastic, can be produced by injection molding, on which the spring catches and / or the catch receptacles are formed for this purpose. The insert consists of intersecting walls which form a honeycomb structure, the cavities enclosed by the walls preferably extending perpendicularly. This standard insert can again be manufactured cost-effectively in large numbers. A recess can be milled into the honeycomb structure using a milling machine, for example a numerically controlled milling machine, the inner contour of which corresponds exactly to the outer contour of the goods to be conveyed (eg bottles). This insert can be quickly adapted to the goods to be conveyed with little effort, so that new pucks can be produced for a conveyor system in just one day can be carried out. These inserts can also be reproduced as required.

The invention is based on the object of showing a puck system and a method for producing a puck, which enable the pucks to be produced in a cost-effective and flexible manner.

The object is achieved by a puck system and a method for producing a puck having the features of independent claims 1 and 9. The features of the dependent claims relating to advantageous embodiments.

A puck system is to be understood in particular as a “modular system” for providing different pucks, in particular for different conveyor systems. In practice it can happen that a manufacturer uses different conveyor systems. Even within a production site, it is possible for several different conveyor systems to be used at different filling systems, each of which requires different outer contours of the pucks.

The puck system according to the invention therefore has, in addition to a first puck that is suitable for one of the conveyor systems, at least one further base body into which at least the insert of the first puck can be inserted with little play and in a predetermined orientation. The further base body is preferably also a hollow body which is manufactured as an injection-molded part from plastic. The further base body has different contours than the first puck and is adapted to the geometric requirements of a different conveyor system. Previously, you had to produce two sets of different pucks if you wanted to transport the same goods on two different conveyor systems. By using the further base body into which the first insert can be inserted, the insert adapted for the first conveyor system can be used on the second conveyor system after it has been inserted into the further base body. It is also possible for the entire first puck with its receptacle to be inserted into the further base body. Additional base bodies can also be accommodated in the puck system, so that a specific insert can be combined with different base bodies of the respective existing conveyor systems. In this way, the number of pucks required for the totality of the conveyor systems can be reduced considerably and thus the costs for the pucks that are used on all conveyor systems can also be significantly reduced.

The first insert can be inserted into the further base body together with the first base body. In a first embodiment, the entire first puck can be inserted directly into a recess in the further base body. The first puck preferably engages with suitable spring catches in the further base body.

In practice, the puck system can also have an adapter insert which can be inserted into the further base body in a predetermined orientation and which has a receiving section into which the base body or the insert of the first puck can be inserted. This configuration enables a very favorable production of essentially pot-shaped components with matching contours, so that both the further base body and the adapter insert as well as the base body and the insert of the first puck can be produced as injection molded parts made of plastic.

In practice, the puck system can have at least one second insert with a receptacle, which can be releasably fastened directly in the further base body in a predetermined orientation by means of at least one form-fitting connection element. In other words, the puck system comprises two variants, namely a first puck variant in which the first base body defines the outer contour, and a second puck variant in which the further base body defines the outer contour. Correspondingly shaped inserts which have a receptacle adapted to the conveyed material can be used both in the first base body and in the further base body. Instead of an individually manufactured insert, however, the first basic body with its insert can also be introduced into the further basic body, possibly with the interposition of the adapter part. In this case, a separate insert does not have to be manufactured for the further base body, but the entire first puck with the first base body and insert can be inserted into the further base body. This insert can therefore be used on both conveyor systems. This makes it possible to work with the same inserts or pucks on different production systems.

Of course, the variants can be combined as required. For a first product shape, the further base bodies can be provided with their own insert and for a second product shape the first pucks can be inserted into the further base bodies.

The adapter insert facilitates the production of the puck system. It is possible to manufacture all parts of the assembled puck, namely from the inside to the outside the insert, the base body, the adapter insert and the further base body as cup-shaped components with complementary contours in an injection molding process. It is also possible to design the adapter insert in such a way that not the entire puck is in the adapter insert, but only the use of the first puck is recorded. The insert can then be fastened in the adapter insert, for example likewise with a form-fitting connecting element, analogously to the fastening of the insert in the base body of the puck. In this way it is possible to use the same insert on the one hand in the base body of the first puck on the other hand in the further base body in different conveyor systems.

In this context, it goes without saying that it is possible to expand the puck system - in addition to the further puck - with additional further variants of the puck in order to make use of inserts in a plurality of conveyor systems further basic bodies can be combined with components of the puck and the further puck.

The method for producing a puck provides that the insert and the base body are produced with at least one form-fitting connecting element and the insert is fastened detachably in the base body in a predetermined orientation and releasably by means of the connecting element. The insert and the base body can have complementary, non-circular shapes so that they only fit into one another in the specified orientation.

Due to the fact that the structural design of the insert and base body prevents the insert from being inserted into the base body in any other orientation or rotatable relative to the base body about the vertical axis of the puck, it can be ensured that a defined positioning of the puck around its vertical axis the conveyor system also results in a correspondingly defined positioning of the material to be conveyed around the vertical axis of the puck.

In practice, the insert can be a plastic part with honeycomb walls and the receptacle can be milled into the insert. This variant for the production of the insert is particularly helpful with complex shapes of the conveyed material or when there is little need for inserts if, due to the small number of pieces, the complex manufacturing process of milling is preferable to mass production by injection molding with expensive tools. Due to the milling of a plastic part with a cellular structure, in the present case honeycomb walls, the weight of the insert is considerably reduced compared to milling from the full material. The resulting amount of waste is also less than when milling from solid.

Alternatively or additionally, at least the insert can be made by 3D printing. Molded parts with the outer shape of the insert and, if necessary, the spring catch or the catch receptacle can be prefabricated, which are then inserted into a holding device of a 3D printer and into which additional plastic material is introduced in the 3D printing process to form the receptacle. This time-consuming but tool-free process is also particularly suitable for small quantities. Alternatively, the entire insert can be produced using 3D printing.

Furthermore, a 3-D printing process can initially be used to create a pattern for use. This sample can be used to check whether the intended design of the insert meets the requirements placed on it. In particular, it can be checked whether the design of the receptacle is actually adequately adapted to the goods to be conveyed. After a successful test, a tool for the production of further inserts can then be manufactured using the injection molding process. In this way, it is possible to avoid costly reworking of the tool or the manufactured inserts, which becomes necessary if it turns out only after the manufacture of the tool that the design of the insert has to be changed so that it can fulfill its purpose.

The tool can in particular be a tool for an injection molding process. In an injection molding process, the manufacturing costs for the tool are usually the main cost factor. With regard to the manufacture of the insert, this means that the tool costs are significantly reflected in the costs for the manufacture of the individual insert.

The insert can be manufactured in a tool that is at least partially made of aluminum or an aluminum alloy. Tools made of aluminum or aluminum alloys only have a short service life when they are used in an injection molding machine. On the other hand, processing aluminum as a light metal is easier and cheaper than processing other materials for casting molds such as steel. The service life of the tool is of subordinate importance for the manufacture of the inserts, since the inserts, which are adapted to a specific material to be conveyed, are only required in a comparatively small number - typically a few 100 pieces.

In practice, a so-called master tool can be used, which has a long service life and is made of steel, for example. The master tool defines the outer contour of the insert, which depends on the inner contour of the Base body or further base body depends and thus remains unchanged even with different materials to be conveyed. In this master tool, so-called cores made of aluminum or an aluminum alloy are used, which create the shape of the receptacle and whose design is adapted to the respective conveyed goods. Complex facilities of the tool, such as, for example, return channels, can be implemented in the master tool. The core can be designed as simply as possible and can be arranged essentially in the region of the receptacle. In this way, the tool costs and thus the costs for the individual uses can be reduced significantly. When manufacturing a new insert, only the new core has to be made from aluminum and inserted into the master tool. The costs for the tool and thus for the production of the insert are significantly lower than those for a complete tool.

As mentioned above, it is possible to first manufacture an insert blank. Although the insert blank can be inserted into the base body with a predetermined orientation, it does not itself have a receptacle adapted to the conveyed item. The receptacle adapted to the conveyed goods is only produced in a further process step by a cutting process (milling). In this way, the application can be adapted to complex conveyed goods. The conveyed goods can be, for example, bottles or flacons with a complicated design. The milling process enables spatial designs of the receptacle that are difficult or impossible to implement with an injection molding process; for example, the insert can have undercuts which, in the case of an injection molding process, would be a hindrance when removing the insert from the mold. In addition, milling does not require a mold, so that milling is faster and cheaper when the number of inserts required is small.

The insert blank can have a cellular structure. A cellular structure is to be understood in particular as a structure in which a large number of cavities are separated by a large number of walls. Examples of such cellular structures are, for example, a honeycomb structure. The cellular structure saves material. In the insert resulting from such an insert blank, the conveyed material is only supported by the webs of the cellular structure. It has been shown that a receptacle formed by such a cellular structure nevertheless enables the conveyed material to be adequately fixed. During the production of the receptacle, in particular by machining, the thin webs of the cellular structure are machined, which can be carried out in a short time. The machined webs provide adequate support for the goods to be conveyed. However, other cellular plastic structures are also conceivable, e.g. insert blanks made of closed-cell rigid foam.

The first puck has a first base body 1 on. Such a basic body 1 is in 1 shown. The outer contour of the base body 1 is adapted to a first conveyor system. The basic body 1 is a plastic injection molded part.

The puck still has a bet 2 on. The use 2 is also a plastic injection molded part. The use 2 can in the main body 1 can be used in a given orientation. For this purpose, the base body has a recess that is open at the top 24 on, which at least in sections has a non-circular cross-section. The use 2 has a complementary cross section, at least in one section, into the recess of the base body, which is open at the top 1 is insertable. This complementary cross section is through the collar 23 formed, which is the upper end of the cup-shaped insert 2 forms. The use 2 is made by means of form-fitting connecting elements 3 in the body 1 attached. The form-fitting connecting elements 3 are designed as spring catches and engage in complementary catches 4th in the form of horizontal slots.

Base body 1 and commitment 2 have a non-circular shape, which the predetermined orientation of use 2 and base body 3 and twisting around the vertical axis H of the puck prevented. Due to the non-round shape of the collar 23 on the mission 2 and the recess 24 in the main body 1 can use 2 only in two positions rotated by 180 ° around the vertical axis in the base body 1 inserted. In the example shown, the orientation is around the vertical axis H through to the use 2 molded projections 5 and 5 ' clearly defined with different widths, those in complementary, also differently wide depressions 6th , 6 ' on the main body 1 intervention. Also, fix the straight sections of the collar in place 23 the use 2 on complementary straight wall sections of the recess 24 non-rotatable. The straight sections of the collar 23 fix the insert 2 in two possible predefined orientations in the base body 1 . This can be sufficient if the filling opening of the conveyed material to be filled is in the middle of the insert 2 is located. The position of the insert is further defined in the embodiment shown. The protrusions 5 , 5 ' and depressions 6th , 6 ' as well as the non-round contour only allow the use 2 in a single orientation in the base body 1 to use. There is only the narrow ledge 5 into the narrow recess 6th fits and the wide lead 5 ' into the wide recess 6 ' must be inserted is in the base body 1 inserted insert 2 (see 13th ) the position around the vertical axis is clearly defined.

The use 2 assigns a recording 7th on that one to the in 3 shown conveyed goods 8th , a perfume bottle, is adapted recess. To the conveyed 8th A ring-shaped additional element on the puck can provide a better grip 9 that in 4th is shown on the insert 2 be put on. The additional element 9 has fasteners for this purpose 10 on that in complementary shots 11 at work 2 intervention. The additional element 9 can also use 2 be welded or glued. It ensures that the conveyed 8th is held stable by the puck.

In 5 is another basic body 12th a puck system according to the invention shown. The further basic body 12th is also designed as a cup-shaped plastic injection-molded part with a non-round, here square, contour. The further basic body 12th is larger than the first body 1 and adapted for transport with another conveyor system.

In 6th is an adapter insert 13th shown, which is in the further base body 12th is insertable. This is also a cup-shaped plastic injection-molded part. The adapter insert 13th assigns a recording 14th to the in 1 shown base body 1 is adapted. The first basic body 1 of the first puck (cf. 1 ) can be included in the recording 14th of the adapter insert 13th can be used.

The assembly of the puck system is in the 12th to 14th shown. In 12th are all components of the puck system from the 1 to 6th , with conveyed goods 8th Shown one above the other and aligned with one another. In 13th is the stake 2 in the first body 1 used to form the first puck. The annular additional element 9 is on the job 2 attached. The fully assembled first puck consisting of a base body 1 , Commitment 2 and additional element 9 is in the middle of 13th shown. After inserting the material to be conveyed (perfume bottle) 8th in the recording 7th this first puck can be placed on a first conveyor system and stabilizes the perfume bottle 8th in a given position. Alternatively, this first puck can be inserted into the adapter part 13th be inserted, which is in the further base body 12th is located, the outer shape of which is adapted to another conveyor system. The entire assembled second puck with perfume bottle 8th is in 14th shown.

In this way, the puck system enables the material to be conveyed 8th both with the first conveyor system to which the first base body 1 is adapted, as well as with the further conveyor system to which the further base body 12th is adapted to promote, with only one in the base body 1 deployable use 2 , its inclusion 7th individually to the conveyed goods 8th is adjusted, is required. For funding with the first funding system, use 2 only in the main body 1 can be used. The puck formed in this way is then attached to the conveyed item 8th and adapted the conveyor system. Alternatively, the one with the main body 1 and the use 2 formed puck in the adapter insert 13th are used, which in turn in the further base body 12th is used. In this way a puck is formed, which is attached to both the conveyed material 8th as well as is adapted to the further conveyor system. It can be seen that the puck system has further components, in particular other base bodies and other shapes Adapter inserts for adapting to other conveyor systems may have. In industrial filling systems, four or more different conveyor systems are sometimes used at one production site. It can be seen that the modular puck system significantly increases the flexibility of the production site with regard to the question of which product is filled by which system and that the overall costs of the pucks for this system can be reduced.

Thanks to the simple locking systems, the different parts of the puck can be quickly and easily connected and separated from one another.

The puck system can also be used for other purposes 15th have that in 7th is shown. The further use 15th is also designed as a plastic injection molded part. The further use 15th has another shot 16 on that to the in 8th shown conveyed goods 17th is adapted in the shape of a bottle for eau de toilette. By inserting further use 15th in the further base body 12th can one to the conveyed 17th adapted further puck are formed, which can be promoted with the further, second conveyor system.

The adapter insert 13th and further use 15th show analogous to use 2 Fasteners 3 in the form of spring catches, which are in corresponding complementary locking receptacles 4th on the further base body 12th can intervene to remove the adapter insert 13th or further use 15th for the conveyed goods 17th in the further base body 12th to fix.

Furthermore, the adapter insert 13th and further use 15th Ledges 5 , 5 ' on that in complementary wells 6th , 6 ' further basic body 12th can intervene to adjust the orientation of the adapter insert 13th or further use 15th relative to the further base body 12th to be determined.

In the 9 and 10 are an insert blank 18th and another blank insert 19th shown. The insert blank 18th can in the main body 1 and the further insert blank 19th in the large, wider body 12th can be used. The insert blank 18th and the further insert blank 19th are also designed as plastic injection molded parts and - analogous to their use 2 and for further use 15th - fasteners 3 and protrusions 5 , 5 ' on.

The insert blank 18th and the further insert blank 19th have a cellular structure, namely a honeycomb structure. The honeycomb structure is made up of a multitude of vertical walls 20th and cavities defined by these walls are formed. From the insert blanks 18th can inserts for the base body 1 or. 12th getting produced. An example is in 11 a mission 21 shown, from the insert blank 19th is made. The recording 22nd of use 21 has been created here by milling. Milling the recording 22nd into the honeycomb structure of the further insert blank is much faster and requires much less material removal than milling into a solid plastic block.
