Description

The present invention relates to a closure technique in which filled bottle containers for liquid products, e.g. bottles or vials, are closed with dispenser caps, and more specifically, to a device for orienting and delivering (transporting) such caps consistently and properly aligned and oriented for capping operations, and can be used, in particular, in the cosmetic, pharmaceutical and chemical industries.

Under the covers in the present invention refers to closures, representing a cap or cap, equipped with a metering pump (dispenser) and a dip tube.

Mechanized filling and capping of bottles has reached a high level of development. The growing number of bottles to be filled and sealed has led to the need for faster and more efficient technologies and machines. In addition, the configuration and design of lids and containers are constantly changing, dictated by function and materials, as well as aesthetic considerations, and such changes have required concomitant improvements in methods and apparatus for handling lids and containers.

A device for capping and sorting caps is known, including a hopper with a feeding belt conveyor, an inclined conveyor for delivering caps to a sorting device containing a separating conveyor and a primary conveyor, a caps separating device, a robotic arm, a return conveyor for caps not assembled by a robotic arm, and a capping machine with vacuum grippers, cells and a six-axis manipulator (hexapod). The known device also includes a feeder that delivers bottles filled with liquid and a bottle conveyor that transports bottles with caps from the capping machine to be shipped to the consumer.

The sorting device also contains a sensor that informs the controller about the presence of caps just before the scraper. The scraper is mounted on a lever located above the separating conveyor. The scraper consists of a cylindrical brush and is driven by a geared motor. The lids are fed by the separating conveyor to the separating device on the primary conveyor where, before being transferred to the separating device, the scraper collects the lids and places them in one layer. The position of the primary conveyor is controlled by the controller of the robotic arm. The lids are collected from the primary conveyor by a robotic arm, which transfers the lids to the secondary conveyor with platforms. The unassembled lids are moved to the unassembled lid return loop, directly onto the return conveyor belt.

The capping machine of the known device contains three capping heads. The six-axis robotic arm comprises levers with single grippers, which additionally comprise three jaws with vacuum suction nozzles mounted on the ends of said jaws.

The bottle is transported to the packaging line, the shape of the pockets corresponding to the shape of the cap, preferably a trigger type cap, sprayer or pump, preferably with a dip tube. The lid lies on its side, horizontally it should contain a dip tube oriented perpendicular to the direction of travel towards the sorting arm, preferably for trigger, sprayer, pump, flip lid, cylindrical, push-on, snap-on or asymmetric lid (application EP 3626677A1, filed 21.09 .2018, published 03/25/2020).

A disadvantage of the known device for capping and sorting caps is the complexity of the design associated with the use of robotic arms in the sorting device and capping machine. Another disadvantage of the known device is its low productivity, due to the need for preliminary orientation of the caps with the dispenser in the hopper and the preliminary separation of the caps before being installed in the bottle on the conveyor leading to the sorting manipulator. Therefore, the design of the sorting device requires slow loading, which ultimately leads to a decrease in productivity. You can also talk about the lack of reliability of the known device, since five bottles and, accordingly, five caps prepared for them, fall under the capping at the same time, and if something went wrong at the capping stage (for example, the cap tube disconnected), the device does not allow removing defective part, because culling occurs long before the capping stage. The unreliability of the device is also due to the presence of vacuum capturing of caps by a robotic manipulator located in the capping machine of the device, firstly, requiring perfectly even (without curvature) and equally long cap tubes, and, secondly, if for some reason there was no capture one of the covers, then all five covers are not captured.

Thus, sorting devices and methods are known in the industry, and these solutions include a separate sorter or a separate sorting insert, each time adjusted exclusively to a certain type of cap. The solutions known so far require changes to the tools that transport the caps from the sorter to the capper, or require adjustment of guides that ensure the correct position of the caps during transport and their smooth movement.

However, this prior art contains some drawbacks related to the unsatisfactory performance of the process.

Thus, a device is known for feeding caps provided with a tube into an orientation device, comprising a disk-shaped body with a vertical axis, a motor for rotating said disk-shaped body at a predetermined speed, and walls that circumferentially limit said disk-shaped body; said disc-shaped body contains a substantially circular wall to support said closures, said wall is air-permeable on the outer annular part, said disc-shaped body is provided with a peripheral annular track, which is defined on the outside by said wall means and is adapted to accommodate said lids located with said tubes, directed upwards (US application US 5031748 A, filing date 06/30/1989, publication date 07/16/1991).

A disadvantage of the known device for supplying lids is unsatisfactory performance associated with low operating speeds of rotation of the orientation device and the turning unit, possible jamming of the mechanisms or destruction of the lids in them, as well as such a design of the orientation device, in which the probability of the lids getting into the cells is extremely small (there are no elements to aid orientation of the caps).

As the closest technical solution, a device was chosen for orienting and delivering dispenser assemblies, having a cap and a dip tube, and advancing along the movement path from the hopper containing randomly oriented lid assemblies to the unloading point, where the lid assemblies (caps) are presented sequentially in a given orientation for capping operations. The device includes means for feeding the lid assemblies from the hopper into an inlet (inclined conveyor) located along the route and means for receiving the lid assemblies at the inlet and transmitting the overall helical motion to the lid assemblies outward from the inlet (orienting device), while allowing the assemblies caps move axially downward relative to the inlet to orient the cap assemblies with their caps located below their respective dip tubes and place the oriented cap assemblies along the generally horizontal first segment of the travel path, means for flipping the oriented cap assemblies to reorient and place the caps along a normally horizontal second segment of the travel path with the lid of each lid assembly lying over the corresponding dip tube and means for advancing the reoriented lid assemblies along the normally horizontal third segment of the travel path to the closure assembly (US Pat. No. 4,610,345A, dated and filed on 03.12.1980, published on 09.09.1986).

The disadvantages of the closest for orientation and delivery of dispenser nodes, as well as other known devices, include slow operation (low operating speeds of the device nodes), and, accordingly, low productivity due to the complex system of transition of covers with dispensers from one node to another and complex coordination speeds of the orienting device and the devices located behind it, as well as the fact that the number of incorrectly oriented and returned covers to the hopper is large. In addition, if the tubes of closures randomly fed into the described device become tangled and interlocked, as is often the case, said device will not be able to unravel them to ensure a regular supply of closures to the closure assembly, then these closures remain on the rotating orienting device and adversely affect the entry of other closures into the recesses (cells).

The technical problem to be solved by the claimed invention is to provide a device for efficient handling of dispenser cap assemblies in order to facilitate the delivery of such caps properly aligned and oriented for capping operations. Yet another additional object of the invention is to provide a device of the type described, with increased simplicity and small size, in order to reduce the cost of manufacturing and maintaining capping equipment while increasing productivity.

The technical result obtained by using the claimed invention is to increase the productivity of the process of supplying, orienting and capping caps with a dispenser on bottles.

The technical result is achieved by the fact that the device for feeding, orienting and capping caps with dispensers on bottle containers, containing a bin of an inclined conveyor, an inclined conveyor, a device for orienting caps with dispensers located behind it, made in the form of a shell with a bottom and a lid, while the latter is made an inlet for lids with dispensers and an opening for unloading lids with dispensers from the orientation device, inside which are located radially oriented cells for lids with dispensers; located behind the device for orienting covers with dispensers, made in the form of guides for the selection and rotation of covers with dispensers; guides, a capping unit and a cap screwing unit with dispensers, horizontally located behind the caps selection and rotation unit, according to the invention, the device additionally comprises a bin located in front of the inclined conveyor bin with a conveyor and agitator located in it and a bottle container rejection unit located between the capping unit and the screwing unit, containing a store of bottles, bottle cutters, a pusher of bottles and sensors for detecting bottles; an air duct with holes located above the horizontal guides, and in the closure assembly there are sensors for defects of caps with dispensers and a device for capturing caps with dispensers, made with the possibility of reciprocating movement to horizontally located guides, under which there is a device for fixing bottle containers and a device for orientation and direction of the tubes of the lids with dispensers into the neck of the container, and in the device for orienting the lids with dispensers there is a surface of rotation adjacent to the edges of the cells, the first and second partitions and two holes in the shell, while the first partition is located parallel to the vertical axis of the orientation device with an offset relative to it in the opposite direction from the inlet, and the second partition is located in the opening for unloading covers with dispensers perpendicular to the vertical axis of the drum; cells of the orientation device are located in the lower part of the orientation device along the periphery, and each cell is formed by an inner wall formed by planes located at different angles of inclination to the vertical, side walls formed by the ribs of the cell, and an outer wall formed by the shell of the device for orienting caps with dispensers.

In this case, according to the invention, the inner surface of the shell can be provided with a damping material.

At the same time, according to the invention, a device for orienting and guiding tubes of lids with a dispenser into the neck of the container can be made in the form of two hollow half-cones with the possibility of reciprocating movement towards each other.

The present invention is illustrated by images (Fig. 1-4), an example of a device for feeding, orienting and capping caps with a dispenser for bottle containers, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the claimed technical result.

The increase in the productivity of the claimed invention is due to the new design solutions used in the feed, orientation and capping device - the presence of new nodes: a hopper with a turner, a rejection node, a screwing node; a new design of the closure unit and orientation device, as well as the use of compressed air as a means of moving caps with dispensers around the device. Moreover, the orientation device has such a solution, in which almost all the caps that have fallen into it will be correctly oriented and fed into the closure. These new solutions of the proposed device and made it possible to feed into the capping unit a significantly larger number of correctly located closures per unit of time compared to analogues, reduced the likelihood of jamming and / or breakage of the device elements and the lids themselves, and also made it possible to remove from the process before the last stage screw caps on defective bottles.

According to the invention, the device for supplying, orienting and capping caps with dispensers for bottles (hereinafter referred to as the capping device) is the following elements arranged one after another and being in structural unity: bin 1 and conveyor 2 of bin 1, agitator 3 located at the outlet of the bin 1. Hopper 1 is a receiving hopper - covers with dispensers are poured into it in bulk. The conveyor 2 is dosing and is located in the hopper 1 and can be placed on a frame structure and driven by a gear motor. The agitator 3 can be made in the form of a blade, separating portions of caps 8 with dispensers (hereinafter referred to as pumps) from bulk, and can have an individual gear motor. Behind the hopper 1 there is a hopper 4 and an inclined conveyor 5. In the conveyor 5 pumps 8 come from the conveyor 1 in portions. The agitator 3 throws a certain number of pumps 8 back into the hopper 1, thus preventing the pumps from accumulating in the hopper 4, and ensures that the pumps 8 are evenly snatched out by the inclined conveyor 5, without interlocking, without spoiling and without disconnecting the tubes from the pumps 8. Rotation of the agitator 3 starts with a short delay after the capping device is turned on and is carried out in the opposite direction of conveyor 1 movement. During operation, the agitator 3 stops when a queue of pump 8 occurs on route 29 and turns off when the device is turned off or in the event of an emergency stop (Fig. 1, 2). At the bottom of the bin 4 of the conveyor 5 there is a sensor that detects the presence of pumps 8 in the bin (not shown). When the sensor does not detect the pump 8 in the bin 4, the control system starts the dosing conveyor 2, from where the next portion of the pump 8 is fed for capping.

If there are no pumps 8 in conveyor 2, the control system automatically turns on the intermittent sound of the siren and the flashing yellow indicator of the light signal column as a warning about the need to load pump 8 into the hopper 1 of conveyor 2.

From the hopper 4, the pumps rise along the conveyor 5 and are fed into the orientation device 6. The conveyor belt 5 has ribs 7 for moving the pump 8 and is driven by a gear motor (Fig. 3, 6).

The device 6 for orienting caps with dispensers is located behind the conveyor 5 and can be made in the form of an orienting drum with the possibility of rotation (Fig. 1, 3, 7, 8) and placed on the support frame with the possibility of adjusting the height of the frame structure. Orienting drum 6 can be made in the form of a shell, closed from below by bottom 9, and from above by lid 10. On the inside, damping material can be applied to the shell, which prevents breakage (defects, destruction) of covers with dispensers when hitting its inner surface. The lid 10 has an inlet 11 through which the pumps 8 enter from the conveyor 5 into the drum 6. The device 6 also has an opening 12 for unloading the pumps 8 from the drum 6, for example, the hole 12 can be made in the shell of the drum 6 on the opposite side from inlet 11. Inside the drum 6, the first partition 13 is made, which is located parallel to the vertical axis of the drum 6 with an offset relative to it in the opposite direction from the inlet 11. The partition 13 prevents incorrectly oriented pumps 8 from entering the inlet 11 directly from the inlet 11 into the hole 12 for unloading pump 8. In the lower part of the drum 6 there is also a second partition 14, which is located in the hole 12 for unloading the pumps, for example, in its lower part. In the embodiment presented in the application, the partition 14 is formed by plates 15 and 16, located behind the gap (slot) 17 between them, perpendicular to the vertical axis of the drum 6 and covering the cells 18 of the drum 6 from above. In other embodiments, the partition 14 may have a different design, for example, in the form of a plate with a through slot. The second partition 14 serves to ensure that incorrectly oriented pumps 8 do not fall either into cells with correctly oriented pumps or into the opening 12 for unloading pumps 8 (Fig. 7, 8, 9).

Inside the drum 6, along its periphery, in its lower part, along the circumference, there are radially oriented cells 18 (pockets, recesses) for pumps 8.

Each cell 18 is formed by an inner wall 19 formed by planes located at different angles of inclination to the vertical, side walls 20, which are formed by the ribs of the cell, and an outer wall 21, formed by the shell of the drum 6. In the shell of the drum 6, 2 holes 22 and 23 are made for entering air into the cells. In the embodiment presented in the application, the hole 22 is located closer to the hole 12 and above the horizontal plane of the cell ribs, and the hole 23 is made below the hole 22 and farther from the hole 12. There may be other options for the location of the holes 22 and 23. Also installed inside the drum a surface 24 of revolution adjacent to the inner edges of the cells 18. The surface of revolution may be in the form of a sphere or, as in the illustrated embodiment, in the form of a cone (FIGS. 7-11). The surface 24 of rotation serves to ensure that the pumps 8 that fall on it roll down and fall into the cells 18.

The gap 17 forms a certain trajectory for moving the pump 8 at the stage of transition from the cells 18 of the drum 6 to the node 25 selection of rotation.

In the lower part of the frame of the drum 6, 2 air blowers (blowers) 26 are installed, from which air pressure is supplied through the air ducts (not shown) into the holes 22 and 23 of the orienting drum 6. The third air blower 27 is located in the upper part of the frame, from it through the air duct (not shown) air is supplied to the guides 28 of the route 29 to move the pump 8 to the capping position (Fig. 3).

The rotation on the drum 6 is transmitted through the bearing assembly from the gear motor.

To the upper frame of the drum 6 fit the node 25 selection and rotation by 180° with the transition to the guides 28 of the route 29 (1, 3, 4, 12).

In addition, on the frame of the drum 6 there is a control cabinet 30 and a tray 31 for collecting single, random pumps 8 that have fallen out of the drum 6 (Fig. 1, 3).

The pumps 8, falling into the drum 6, under the influence of gravity and the forces of inertia of rotation of the drum 6, roll down the cone 24 to the edges of the drum 6 until they fall into the cells 18 in the position - cover down, tube up (these are correctly oriented pumps). However, pumps 8 can fall into cells 18 and incorrectly oriented at different angles, or 2 or 3 pumps can fall into one cell 18. The angles of the inner wall 19 of the cell 18 are selected experimentally so that the incorrectly located pumps 8 in the cell 18 are pushed out of the cell 18 by air through the holes 22 and 23. Only correctly oriented pumps 8 are not affected by the air movement, and they freely enter the gap 17 between the plates 15 and 16 partitions 14 (Fig. 7).

Air is supplied through holes 22 and 23 in the shell of the drum 6, with the help of which incorrectly oriented pumps 8 are thrown back from the edge to the central cone 24 until they fall into the cells 18 along the edges of the drum 6 in the correct position - tube up.

The node 25 of selection and rotation by 180° is rounded guides (crescent-shaped, arcuate), sliding along which the pumps 8 are turned over into position with the covers up, tubes down, i.e. by 180° (Fig. 1, 3, 4, 11).

From the guides of the assembly 25 of the rotation of the pump 8, they pass to the horizontal guides 28 of the route 29. Above the route 29 there is an air duct 32 with holes 33 in the lower part, through which air is supplied to the route 28 with pumps 8. Under the pressure of the air flow from the holes 33, the pumps 8 slide along guides 28 and enter the capping unit 34.

On the guides 28 of the route 29, sensors are installed that monitor the occurrence of a congestion of the pump 8 on the route 29 (not shown). At their signal, conveyor 2, agitator 3 and drum 6 stop. Upon receipt of a signal from these sensors, the control system automatically stops the rotation of agitator 3 in conveyor 2 and drum 6, as well as the movement of conveyors 2 and 5 until the sensors on track 29 stop supplying a signal about the presence of a queue of pumps 8 (Fig. 1, 4).

The capping unit 34 is a frame structure on which the air duct 32 for route 29 is fixed.

Behind the guides 28 of the route 29, in the upper part of the closure assembly 34, there is a device 35 for gripping the pumps 8, which is made with the possibility of reciprocating movement to the guides 28 (Fig. 12). Under fixture 35 are fixture 36 for fixing bottle container 37 and fixture 38 for orienting and guiding pump tubes 8 into the neck of the container (FIG. 13). In addition, in the capping unit 34 there are sensors 39 for defects in caps with dispensers, for example, it can be a sensor for an open pump 8 and/or a sensor that detects the presence or absence of a tube in the pump 8 (Fig. 15).

On the frame of the capping unit 34, special sensors for detecting objects can also be installed, which determine the presence of a bottle at the capping position and give signals for the movement of pneumatic cylinders with cutters 40 of the bottle container 37 (Fig. 13). The bottle 37 enters the capping unit 34 along the conveyor of the operating line of the consumer, abuts against the first cutter 40, one of the sensors is activated and closes the second cutter 40 (not shown), locking the bottle 37 at the capping position. Next, the bottle is fixed by the neck with the help of devices 36, which can be made, for example, in the form of two grips. Device 38 can be made, for example, in the form of two hollow half-cones, forming a funnel when closed. Fixture 38 is used to center the pump tubes 8 and to get it into the neck of the bottle 37 clearly. Thanks to fixture 38, possible defects in the pump tubes 8 in the form of curvature and/or tubes of different lengths are leveled. The grips of the device 36 diverge to the sides, releasing the neck of the bottle 37, the pump 8 is lowered into the bottle. The first cutter 40 opens, releasing the bottle 37 from the capping position, the second cutter 40 opens, passing the next bottle 37 into the capping mechanism, and the cycle repeats.

All pneumatic cylinders of the capping device are equipped with magnetic rod position sensors for the possibility of centralized automatic control of their position and control.

Behind the capping unit 34, there is a rejection unit 41 for bottles 37. The reject unit 41 includes an accumulator 42 for bottles 37, cutters 43 for bottles 37, a pusher 44 for bottles 37, and sensors 45 for detecting bottles. After the node 41 for rejecting bottles 37, there is a node 46 for screwing the caps with dispensers, in which the caps on the bottles are screwed up to the stop (Fig. 1, 5, 15). Between the capping unit 34 and the rejecting unit 41, a monitoring system can be installed based on the technical vision of bottle defects and/or defects in filling liquid products into bottles and/or other defects.

The inventive device for feeding, orienting and capping caps with a dispenser for bottles works as follows.

Pumps 8 are poured into bunker 1 in bulk. Pumps 8 are poured into bin 4 in batches along conveyor 2 with agitator 3, from where they rise along inclined conveyor 5 into orienting drum 6. Under the pressure of air supplied through technological holes 22 and 23 in orienting drum 6, pumps 8 fall into the cells 18 of the drum 6 in a predetermined position - cover down. When leaving the drum 6, the pumps 8 are turned over in the node 25 of selection and rotation by 180°, with the lids up and the tubes down, and under the action of air pressure they slide along the route 29 to the node 34 of the capping. Pumps 8 are fed to the capping position one by one, passing through the system of fixtures 35 and 38, and lowered into bottles 37 that have entered the capping unit 34. With the help of sensors 39, the procedure for diagnosing the defect of the pump 8 is carried out, and with the help of node 41, bottles with a defective pump or bottles with a defect are removed from the process flow if a vision system is used. The control system identifies the bottle by its serial number. For example, a bottle under a certain serial number with a defective cap has left the capping unit 34 and, when approaching the rejection unit 41, is identified by sensors 45; the control system gives a signal, and the flow of bottles is stopped by means of cutters 43. The rejected bottle is separated from the flow by a pusher 44, which pushes the bottle into the accumulator 42. Then cutters 43 open and the flow of bottles resumes movement.

The cycle of operation of the device for supplying, orienting and capping caps with a dispenser for bottle containers is completed by releasing the bottle with a screwed pump from the assembly 45 and moving the next bottle to the screwing position.
