Description

The present invention relates to a device for pressing at least one company Material body with low density, with a feed device, with a press device and with a pressing body discharge device, the pressing device two opposite, movable press plates includes.

Furthermore, the present invention relates to a method for pressing mindes tens of a fibrous material body with a low density, the fibrous material body a pressing device is supplied, the fiber material body between two overlying pressing plates and the resulting pressing body is discharged from the pressing device.

In addition, the invention relates to a pressed body made of at least one fiber material body per with low density, which is obtained in particular by the method.

Finally, the invention relates to a press plate.

Fiber material bodies with a low density are in the construction sector, especially with regard on insulation materials or in the area of hygiene articles. The fibers are specific requirements. Moisture is particularly important in the area of hygiene products absorption capacity of the fibers in the foreground. In apparatus, vehicle and house building the insulating effect of the fibers when used for heat, cold and sound insulation purposes by Importance.

In view of increasing transport and storage costs, companies made from loose fibers Material material bodies are not supplied in this form, but are strongly ver seals and usually packed. Several fiber material bodies, for example in Form a plate stack, pressed and then wrapped. Both single fiber mate Rial body as well as fiber material packs - wrapped or not wrapped - are in turn converted into an intermediate product, in which case either several individual bodies, such as fiber roll, or several packs, such as a stack of sheets, into a single compact be lubricated, which is packed, banded or strapped after the pressing process.  

From practice it is known that the on the fiber material body, the multiple individual body or several plate stacks acting press forces on one side. With others Words, one press plate remains at rest, while the other press plate is used for ver seal of the material to be pressed is moved against the first press plate.

A one-sided press force application results, for example, from FR 2 697 228. The dorti ge device for pressing and packaging several fiber material bodies in shape of cellulose stacks, namely diaper piles, comprises means for compacting the Cellulose stacks, means for guiding the cellulose stacks towards a sack shaft, at least one pair of juxtaposed press plates, the plates in two positions can be adjusted. One position relates to the spacing of the plates in a certain plate spacing, which is greatest at a certain thickness of the cell cellulose moistened stack. The other position concerns the approximate position of the plates. A pressure piece first transports the cellulose stack between the plates, which are separated Position. The plates are then moved and take the cell at the same time loose stack with yourself. At the end of the move, a plate is locked while the other plate is moved further and the cellulose stack to the specified thickness compacted. After the compression, the compressed stack is removed from the pressing device encountered, fed to a bag and packed there.

The one-sided application of press force adversely affects the quality of the processed finishing product. The one contacting the press plate with effective press force The area of the material to be pressed is compressed much more than the subsequent area Pressed area. There is a constant reduction in pressure within the press good in the direction of the press plate at rest. The weak point is the one with the press Powerful press plate contacting area of the pressed material, in which as a result of the ho hen pressing force fibers are destroyed. In the area of hygiene articles, this can be reduced Conduct moisture absorption. In the construction sector, the destruction of the fibers has negative results effects on the elasticity behavior of the fiber material. If the thickness reset If the fibers are not guaranteed, the insulating effect during use can also be ensured in apparatus, vehicle and house construction when used for heat, cold and sound insulation purposes cannot be guaranteed in high quality.  

In the case of the fiber material body compression known from practice, the feed is also tion of several individual bodies, such as fiber rolls, or several packages, such as a stack of plates, in the press facility in need of improvement. Vertical presses are still one today largely manually supported feeding of the pressed material is common, sometimes an inclined Press construction practiced to prevent the pressed material from falling over on a conveyor belt prevent.

Another disadvantage is the fiber material body compression known from practice in that the detachment of the compact from the press plates after the pressing process often with damage to the wrapping material or even the compact surface che goes along.

The invention has for its object a device of the type in question admit that is optimized compared to the state of the art. With a view of the compact is a qualitative optimization, with a view to the fiber material body feed a time drawn optimization can be achieved. Furthermore, a method of the in question Specified, which a high compression of the pressed material on receipt of the Fiber quality enables. In addition, a high quality compact is to be created become. Finally, a press plate of a device of the type in question should be such be further developed that problem-free detachment of the compact from the press plates can be done after the pressing process.

The above task is carried out with regard to the device and with regard to the qua litative optimization of the compact, solved by the features of claim 1. Thereafter, a device of the type in question is designed and further developed in this way det that both press plates can be positioned individually so that the at least one Defi fiber material body for generating a defined pressure gradient in the pressed body press force can be applied.

First it was recognized that the fibers of a fiber material body pressed on one side pers or several fiber material bodies pressed on one side in the contact area for moving th press plate and in the adjoining area deteriorated properties, in particular especially have a deteriorated elasticity behavior. According to the invention, it was recognized  that an impairment of the fiber properties avoided and the quality of the Pressed product can be increased if the pressing force from both press plates on the or the fiber material body is applied. By distributing the for compaction the amount of force required on two opposing press plates, the load on the company significantly reduced in the contact area to the press plate. For the invention it is we Significantly that the two press plates can be individually positioned so that the or Defi fiber material body for generating a defined pressure gradient in the pressed body is or can be acted upon with press force. This opens up further Possibilities, the amount of force in the required percentage distribution on both sides bring to. For example. would be the formation of non-uniform pack assortments made of fiber material material plates possible, which would then be applied unevenly with pressing force.

Drive and control means are expediently used to position the press plates provided which operate electrically and / or hydraulically and / or mechanically. For example. could serve as a drive and control means per press plate with a servo motor and rack be seen. Hydraulic cylinders could also be connected to a displacement sensor.

According to a particularly preferred embodiment of the device according to the invention the drive and control means could be computer controlled. A further could compression body-specific compression file can be provided, which contains the data for the Positioning each press plate delivers.

Depending on the design of the device in the sense of a horizontal press, a vertical press or an inclined press, the press plates could be perpendicular, parallel or inclined to Extend underground.

The fibrous material body could be in the form of a fiberboard, a fiberboard stack or a fiber roll and, for example, as an insulating material in apparatus, vehicle and house construction are used.

In the case of a particularly important type of device, namely the so-called Mo dulpack press, several fiber material bodies could be in the press in one operation direction can be pressed. For example. could have at least six rolls or stacks of fiber stock  partial wrapping or compressed without wrapping. The wrapper could made of foil, paper, mesh or the like. in the form of a sack, a hose or a banderole. Alternatively, the fiber material bodies could also be strapped.

With regard to the feed device, this could comprise a conveyor belt on which chem the or the fiber material body are transported to the pressing device. After egg In a particularly preferred embodiment, the conveyor belt is a telescope band, which allows automatic feeding. A horizontal press could a shelf upstream of the pressing device for the fiber (s) being transported material body may be provided. Depending on how many of the fiber material bodies in one Process could be compressed, this by the different extension lengths extendable telescopic belt can be successively placed one behind the other. The filed The fiber body or the deposited fiber body could then be fed into the Pressing device to be placed between the press plates. The direction of movement of the Feed slide could be oriented perpendicular to the transport direction of the conveyor belt his.

A tray and a feed slide are not required for a vertical press. The extendable section of the telescopic belt could be moved directly into the pressing device and lay the fiber material body on the lower press plate. If more a fiber stack could be formed. The lower one Press plate could first be moved upwards and the first fiber material body per and finally gradually - with increasing stack height - down be moved.

The assignment of a telescopic cover tape above the Te is particularly advantageous Leskopierbandes, regardless of whether it is a horizontal, vertical press or a inclined press is used. Due to the telescopic cover band, the positive guidance allows the fiber material body and effectively prevents the same from falling over. Also Pre-compressed fiber material bodies in the form of packages with strongly rounded edges can can be transported standing up. The distance between the telescopic belt and the telescope pierdeckbandes could be matched to the dimensions of the fiber material body or be set to this. Another advantage of assigning a telescopic cover tape  - especially in connection with the horizontal press - is seen in it hen that the fiber material body upright and / or with the least possible contact surface can be transported to the telescopic belt and to the telescopic cover belt. As a result, the company to be compressed assumes the starting position of the press material material enables and achieves a high band utilization in quantitative terms.

The press body discharge device downstream of the pressing device could turn off include push hopper, the dimensions of which depend on the compacts to be achieved measurements is adjustable. Alternatively, for a press that could not be converted, for a product also a according to the dimensions of the compact to be achieved selected discharge funnel.

After the embodiment of the invention that is used most frequently in practice According to the device, this also includes a packaging device for packaging the Press body using sack, tube, stretch film, wrap, banderole, strapping or the like .. Especially when there is a large number of fiber material bodies to be pressed Packaging expedient, which the existing from the sub-body in Shape holds and prevents reshaping due to the elasticity behavior entry. The packaging device could be assigned to the discharge funnel or to this be immediately subordinate. Are at least partially wrapped or strapped fiber mate rial body was pressed to the pressed body, it now comes to the second coating or strapping the entire module.

After the press plates are moved together and the desired compression di the pressing body is reached, the pressing body is moved from the pressing device into the Discharge funnel spent. This could be done using an ejector. Preferably the press plates remain in their collapsed position during extension tion and are not even slightly moved apart so that the pressed body itself not reshaped or deformed as little as possible until the packaging is complete.

If the ejector pushes the press body to the press plates with little play Pushes out the funnel, especially with regard to already covered fiber material body the packaging material or the fiber material itself on the press plates  get stuck. So now a detachment of the compact from the press plates nevertheless can be done easily, two alternative structural measures could be taken to the press platform ten or at least be carried out on a press plate.

A structural measure could consist of a rotating belt on the press plate provided. The belt could be on the press plate in the transverse direction, with a running direction parallel to the ground and with an orientation towards the extension funnel to run. The circulating belt could not only detach the possibly encased compact effect from the press plates, but also the transport to the discharge funnel. in provided that no additional push-out would be required with such a measure. The ever circumferential belts assigned to a press plate could be coordinated with one another to be controlled. There could be a speed regulation according to the surface surface of the material to be loosened and possibly transported.

As an alternative or in addition to the circulating belt, the press plate could also be used Compressed air through openings on the fiber material body or Press body-facing press plate surface. A press designed in this way plate with the features according to claim 39 solves a sub-task of the present Invention and is on every type of press and the most diverse press goods.

According to the invention, it was recognized that an air cushion in each case was caused by the incoming air is formed between the press body and the press plates and thus the detachment of the Press body easier and stuck packaging or press material is largely prevented.

When compressed air pressurized openings in connection with one the tape are used, the air cushion acts on the tape against the Press plate counter. The at least partially due to the passage openings as a hollow Press plate present in the body nevertheless has sufficient stability for implementation tion of the pressing process. The passage openings could be homogeneous over the entire Press plate area may be distributed or also at recognized problem areas. The connections for an internal compressed air line, the contact area to the compact could be assigned by the part of the press plate facing away.  

Furthermore, the above task with regard to the method by the Features of claim 22 solved. After that, a procedure will be in question the type, in particular using the inventions described in claim 1 device according to the invention, performed by the at least one fiber material body to create a defined pressure gradient in the compact defined with pressing force is applied by positioning the two press plates in opposite directions.

As with the device according to claim 1, the method is also recognized been pressurized on both sides to reduce the amount of force leads, which would be necessary with one-sided pressing. In this respect it is amazingly simple Refers to the long-standing problem of fiber damage in the contact area pressing plate effective in the pressing force and in the immediately adjacent area solved the rather high compression forces when one-sided press force was applied.

With regard to further advantageous refinements of the method according to the invention is based on the general description of the device according to the invention saying 1 and to the general description relating to the press plate according to the invention referred to claim 35, especially since features are explained there for the procedure are also relevant.

The above task is also performed with regard to the compact Features of claim 28 solved. After that is a press body in question the type characterized by largely undestroyed fibers in the press plate contact area and in the area adjoining the press plate contact area and thus by largely uniform elastic behavior of the compact in all areas.

Due to the press force of the fiber material body (s) on both sides with less pressing force in the fibers on the fiber material (s) body are acted on and still a high compression can be achieved. Since the Fibers are hardly affected during the pressing process negative effects on the material properties of the fiber material. In the hygiene area it remains, for example, with the desired moisture absorption behavior. In the construction area  is the undisturbed elasticity behavior of the fibers and thus the dimensional accuracy and the insulating effect of the insulation material during use in apparatus, vehicle and house building when used for heating, cooling and sound high quality protection.

With a view to a common use case, with two opposing presses the same amount of pressing force is applied, this type of pressing force is applied Impact that the compact is largely symmetrical, with the symmetry plane is placed in the middle and perpendicular to the longitudinal axis of the compact. Besides, could also a symmetry of the compact can be achieved in that the symmetry plane runs in the middle and parallel to the longitudinal axis of the compact. If a single company compressed material body, the outer areas are deformed more than the inner Areas because the pressure gradient decreases away from the force application area. If of two opposing press plates have the same amount of pressing force on each other ordered fiber material body was applied, are the inner part of the body Press body deformed less than the outer part body of the press body.

Finally, the task set out above with regard to the device and in the out look at their time-related optimization, by the features of claim 32 solved. Thereafter, a device of the type in question is designed and white educated that the feed device comprises a telescopic belt.

According to the invention, it was first recognized that a time saving in the area of the company material body feed can be located because there are still manual operations ge take place. Furthermore, it has been recognized according to the invention that time-saving feeding tion of the material to be pressed to or directly into the pressing device when the feed device comprises a telescopic belt known per se. Through the retractable and extendable Telescopic belt is not only a faster one, but also an exact one with precise position Delivery of the fiber material body possible.

In the case of a vertical press, the telescopic belt protrudes temporarily into the press in the extended position device into and in the retracted position the fiber material body is in the press device tion is deposited on the lower press plate, which extends parallel to the substrate.  

If the retraction and extension are repeated, they are successively superimposed several supplied fiber material bodies and thus to form a stack.

In the case of a horizontal press, the telescopic belt could temporarily be in the extended position protrude the area of a shelf upstream of the pressing device. During the Retraction of the telescopic belt, the fiber material body is placed on the shelf. Repeating retraction and retraction successively results in consecutive lying several supplied fiber material bodies on the shelf. It becomes a bunch of fiber formed material bodies, which then between a total of a feed slide pressing plates extending perpendicular to the substrate can be moved.

Regardless of whether the device claimed with claim 32 only one term press force application realized or as claimed in claim 1 Device has two oppositely exactly positionable and controllable press plates, the design of the feeder as a telescopic belt represents the degree of automation the device increasing advantage.

Further advantageous embodiments of the device claimed in claim 32 follow from the general description of the device according to the invention Claim 1, where features, for example. Regarding the feed slide, the pusher and the telescopic cover tape and the compact packaging device are also relevant for the device according to claim 32. Also is for the device claimed with claim 32 also the general description important with respect to the press plate according to the invention according to claim 35 times has these features that are also relevant to the device in question.

In summary it is stated that with the device according to the invention in your two main versions, namely two mutually controllable and positio nable press plates for the defined application of press force on the one hand and feeding of the On the other hand, fiber material body by means of a telescopic belt, a qualitative and temporal opti Mation compared to the prior art is achieved. Ultimately, it becomes a press product receive which is high quality and inexpensive to manufacture and during transport or does not require more space during storage than before. In the technological context  with the two devices, the method and the compact also stands the press plate according to the invention, which has a positive influence on the quality of the pressed body and favoring the pushing out in terms of time.
