Empty and/or full cans (1, 2) are arranged on the carriage in such a way that the empty cans (1) are placed at one end of the carriage (10). The full cans are placed at the other end of the carriage (10).

Description

Method and device for magazinizing cans

The invention relates to a method and a device for magazining cans, in particular on a fiber-band-producing machine, to which empty cans are fed from the magazine and from which filled cans are fed to the magazine, in which filled cans are removed from the magazine and replaced by empty ones Pitchers to be replaced.

Generic methods and devices are known from DE 40 15 938 AI. A can transport vehicle is thereby moved up to a can magazine and gives an empty can in a vorgese for empty cans ^h enes magazine from. The can transport vehicle then travels a certain distance, so that it can receive a full can from a magazine for full cans. Like the full cans in the magazine, the empty cans are each fed to a removal point by means of a storage conveyor. The magazine must also be designed in such a way that it can accommodate as many empty cans as full cans at the same time. This means that a large space is required for the can magazine.

With the accumulation conveyor, empty cans can only be handed in at the end of the storage path for the empty cans. On the other hand, full cans can only be reliably picked up at the beginning of the storage section. This has the disadvantage that the can transport vehicle has to travel to several positions for dispensing and receiving the cans.

It is therefore an object of the present invention to provide a method and a device with which cans can be placed in a magazine and removed therefrom with little construction and control effort.

The object is achieved by the features of claims 1, 9, 10, 11 and 14.

According to the invention, the magazine is displaced for taking up and taking down the can, so that, depending on requirements, an empty can space, an empty can or a full can is fed to a can gripping device. An advantage of this method according to the invention is that control of only the magazine is required. The feeding and removal of the cannons advantageously takes place at the same location. A shifting and costly positioning of the devices for removing and feeding cans from and into the magazine is avoided. By moving the magazine, the required position on the magazine is made available to the can gripping device. This makes it possible for the jug gripping device to either pick up an empty or full jug or to place an empty or full jug on the empty jug parking space.

By using the magazine as an exchangeable memory, it is advantageously possible to exchange a magazine provided with filled cans for a magazine provided with empty cans. This largely avoids downtimes when filling cans. If fewer filled cans are removed from the magazine than are fed into the magazine by the machine, the completely filled magazine can be removed from the machine manually or automatically and replaced with a magazine with empty cans.

Advantageously, a filled jug is removed from the magazine at a time when another jug is outside the magazine, for example when the jug is being filled. At this time there is an empty can space in the magazine, on which an empty can is dispensed into the magazine for a full can that has been removed. An orderly storage of the cans on the magazine and thus the possibility It is then possible to change the can by slight movement of the magazine if the filled cans are placed on one side of the magazine and the empty cans on the other side of the magazine.

Advantageously, for a full can that is removed from the magazine, an empty can is placed in the magazine. This means that there is always the same number of cans in the magazine before and after the can changing process. In order to maintain order in the magazine, it is advantageous if the jug is always removed from the magazine, which is the first full jug seen from the direction of the empty jugs. According to this principle, it is also advantageous if the full can following the row of empty cans is first removed from the magazine.

Advantageously, the exchange of the empty can against the full can is such that a space is free on the magazine between the empty cans and the full cans after the change. The jug in the machine for filling is set back in this position and connects to the row of full jugs. The empty jug located next to this reset full jug is removed from the magazine after the magazine has been shifted by one jug parking space and is fed to the machine for filling. This in turn has created a free parking space which can be used by a can transport vehicle to deliver an empty can. If there is an empty can parking space on the can transport vehicle on the side of the full cans of the magazine, the full can and the empty can can be handed over without a large displacement path or repeated positioning of the magazine.

According to the invention, the can magazine is a carriage on which empty and / or full cans are arranged in such a way that at one end

SPARE BLADE the empty cans of the car and the full cans are parked at the other end of the car. With this arrangement of the empty and full cans on the trolley, the method described above can be carried out in an advantageous manner. The carriage is open on both sides of its longitudinal direction so that it can be loaded and unloaded with cans. This makes it possible for gripping devices to grip and move the cans placed on the wagon from both sides of the wagon. By means of a friction wheel drive which acts on a friction surface of the carriage, the carriage can be displaced by one can parking space. By means of a shoulder in the counter roller of the friction wheel drive, the height alignment of the carriage can be carried out in a simple manner such that the gripping devices can grip and move the cans at defined locations.

The cans are parked on the pitches with side guides by side guides on the trolley. A defined location of the cannons is achieved by the lateral guides.

If there is more can space on the car than is necessary for the cans to be filled, then in particular in the case where there are only empty or only full cans on the car, the change to a full or empty cans after the same This enables methods such as mixed loading of the wagon. The can change can also e.g. at a point where a can is not removed from the magazine for filling on a machine.

If the trolley width is smaller than the can diameter or the can length, the cans' protrusion from the cans will make it easier to pick up the cans. A can gripping device can reach under the cans and push them from or onto the trolley.

REPLACEMENT LEAF To position the trolley with respect to a can parking space relative to a can gripping device, it is advantageous to have a positioning means assigned to each can parking space of the trolley.

By arranging a sensor, the readiness for picking up or dispensing of cans of the trolley can be indicated to the can transport vehicle. This prevents the gripping device of the can transport vehicle from accessing the cans of the car while a just filled can is being dispensed by the machine onto the car. In addition, the machine can thereby be shown that a can change is currently being carried out with the can transport vehicle, so that a can cannot be removed by the transport device of the machine.

Exemplary embodiments of the present invention are described with reference to the figures. Figure la-d shows a can changing process,

Figure 8 shows a device immediately before the can change process

In the figures la - l the process of changing the can is on shown in a magazine. FIG. 1 a shows a carriage 10 as a magazine for empty cans 1 and full cans 2. The carriage 10 can be moved back and forth in the sliding area 21. A free can parking space 5 is provided between the empty cans 1 and the full cans 2. A can, not shown, which finds its place between the empty cans 1 and the full cans 2 on this free can parking space 5, is conveyed out of the magazine, for example, for filling with sliver on a transport device 22. This can, not shown, is returned to the magazine after the filling process on the transport device 22. A can transport vehicle 3 moves along a route 4 in the direction of the arrow to next to the carriage 10. The can transport vehicle 3 stops next to the carriage 10 in a defined position. Two can parking spaces 5, 5 'are provided on the can transport vehicle 3. In the vehicle 3 of this exemplary embodiment, the can parking spaces 5, 5 ′ are located behind the actual vehicle 3. The can transport vehicle 3 is loaded with an empty can 1 on the one can parking space. The second can parking space 5 'on the can transport vehicle 3 is empty. A can gripping device 30, 30 'is assigned to each can parking space 5, 5'. With the help of this can gripping device 30, 30 ', cans are picked up and given off by the can transport vehicle 3.

The vehicle 3 is positioned next to the carriage 10 in FIG. 1b. The position of the can transport vehicle 3 is such that the empty can 1 on the transport vehicle 3 faces the empty can parking space 5 of the carriage 10. In this position, the gripping device 30 'is extended and grips the full can 2 standing next to the empty can parking space 5 of the trolley 10. The empty can 1 is pushed by the gripping device 30 onto the empty can parking space 5 of the trolley 10. By pulling back the gripping device 30 ', the full can 2 is pulled from the carriage 10 onto the can transport vehicle 3. The gripping device 30 is uncoupled from the empty can 1 and also withdrawn (FIG. 1c).

According to FIG. 1d, the can transport vehicle 3 travels away from the magazine on route 4 after the can change has been carried out and fulfills its transport order, for example by drives to a sliver processing spinning machine and there changes the full can 2 to an empty can 1. The carriage 10 is clocked further by a can parking space, so that the free can parking space 5 on the carriage 10 again faces the transport device 22. The carriage 10 is thus ready to take up the can removed for filling again.

The can pick-up and take-off takes place via a can-grip device 30 which is not described in detail. This can-grip device 30 can be designed in such a way that it grasps the can 1, 2 with a handle provided for this purpose, lifts it up if necessary and onto the or promoted by the carriage 10. Advantageously, however, the hook engages under the can 1, 2 to move the can 1, 2. This means that no, or only minor, structural changes, e.g. Reinforcement of the walls on the cans compared to standard cans is required. Can gripping devices of the type described are suitable for both the carriage 10 and the transport device 22.

The magazine is shown in more detail in FIGS. 2a-2c. The sliding area 21 is arranged next to a machine 20. The transport device 22 is provided for the transport of cans from the carriage 10 to the machine 20. The transport device 22 grips a can 1 and conveys it from the carriage 10 to the machine 20. On the machine 20, the empty can 1 can e.g. be filled with sliver. After the pre-filling gas, the now filled can 2 is conveyed back onto the carriage 10 by means of the transport device 22. Guides 23 are arranged in the sliding area 21. The carriage is in these guides 23

REPLACEMENT LEAF 10 introduced with its wheels. This ensures that the carriage 10 is guided during its back and forth movement, even if, for example, the carriage 10 is struck.

In addition to the transport device 22, a friction wheel drive 24 is provided. A friction wheel 25 interacts with two counter-rollers 26 in the friction wheel drive 24. The carriage 10 is moved back and forth by the friction wheel drive 24. For this purpose, the carriage 10 is inserted with a spar 11 between the friction wheel 25 and the counter-rollers 26. The friction wheel 25 thus presses against the spar 11, which in turn is supported on the counter-rollers 26. This creates a sufficiently strong frictional connection, through which the carriage 10 can be driven.

As shown in FIG. 2b, the carriage 10 is completely pushed into the magazine at the start of the filling process. At the beginning of the filling process, the carriage 10 is in an end position of the sliding area 21. A can is removed from the carriage 10 via the transport device 22. This creates a free can parking space 5 on the carriage 10.

According to FIG. 2c, the carriage 10 is pushed in the course of filling the individual cans in the direction of the other end of the sliding area 21. In the course of filling the individual cans, full cans 2 are arranged at one end of the carriage 10 and empty cans 1 at the other end of the carriage 10. Between the empty cans 1 and the full cans 2 there is an empty can parking space 5 during the filling process of a can. The filled can 2 is pushed back into this empty can space 5, the carriage 10 is clocked further by one can space and the next empty can 1 can be conveyed to the machine 20 by means of the transport device 22 for filling.

FIG. 3 shows a side view of the carriage 10. Wheels 12 and 13 are connected to one another via a spar 11.

REPLACEMENT LEAF The wheels 12 are designed as steering wheels, so that the carriage 10 can be moved outside the magazine. Can guides 14 are arranged on the spar 11. The spacing of the can guides 14 from one another provides a defined placement of the cans on the can parking spaces 5.

Sensor cutouts 15 are arranged in the spar 11. The sensor cutouts 15 interact with two sensors 28, 28 '(FIG. 2) on the magazine. The sensors each recognize the end of a cutout 15. This makes it possible to position the can positions 5 exactly with respect to the transport device 22 from both directions of movement of the carriage 10. The sensors 28, 28 'are arranged next to the transport device 22 so that they do not hinder the transport path of the cans. Correspondingly, the cutouts 15 are located on the spar 11 next to the associated can parking space 5 to be positioned.

A handle 16 is arranged on the carriage 10. By means of the handle 16, the carriage 10 can be inserted into the magazine with empty cans 1 and removed from the magazine after the cans have been filled. This has the advantageous effect that the machine 20 can continue filling empty cans, even if a carriage 10 is already filled. The filled trolley 10 can be driven into a warehouse from which it is gradually unloaded, for example by means of can transport vehicles 3, according to the method according to the invention. It is also possible that the trolley 10 with filled cans for e.g. sliver processing machines is pulled and there the empty with the full cans of the carriage 10 are exchanged manually.

FIG. 4 shows a top view of a carriage 10. The carriage 10 can be moved by means of the steering wheels 12 and the fixed wheels 13. In the area of the magazine, the spar 11 is coupled to the friction wheel drive 24. The spar 11 is located

REPLACEMENT LEAF between the friction wheel 25 and the counter-rollers 26. Two positions of the friction wheel drive 24 are shown in the illustration in FIG. The position of the friction wheel drive 24 shown on the left in FIG. 4 is the position which is present on the carriage 10 at the start of the filling process of the cans. During the filling process, the carriage 10 moves to the left in cycles, so that finally the right position of the friction wheel drive 24 with respect to the carriage 10 is present during the filling process of the last can. The spar 11 must therefore be designed so that it enables the carriage 10 to be positioned by means of the friction wheel drive 24 even for the last can parking space.

The friction wheel drive 24 is outlined in FIG. The friction wheel 25 presses the spar 11 against the counter roller 26. A sufficient frictional engagement is thereby achieved which allows the carriage 10 to move. The counter roller 26 is stepped in its diameter. This advantageously has the effect that the height alignment of the carriage 10 in relation to the can transport vehicle 3 and the transport device 22 is always such that the can 1 can be taken over well.

As can be seen from FIG. 5, the can 1 protrudes laterally beyond the carriage 10. This advantageously has the effect that the can 1 can be gripped by a gripping device of the transport device 22 and a gripping device 30 or 30 'of the can transport trolley 3. It has proven to be advantageous that a hook is pushed under the can 1 and takes the can 1 with it when it is pulled back.

FIGS. 6a-6c show a further procedure for taking over the can. In the vehicle 3 shown in these figures, the can positions are arranged between the chassis. In contrast to the vehicle 3 of the figures la-d, the empty can is in the front in the direction of travel. This is advantageous, especially when replacing the cans on a

REPLACEMENT LEAF A sliver processing machine, since the exchange can take place without the vehicle 3 having to drive backwards.

In FIG. 6a the can transport vehicle 3 is positioned next to the magazine in such a way that its empty can 1 is opposite the first empty can (seen from the direction of the full can 2) of the carriage 10. In addition to this first empty can 1 of the carriage 10, there is the free can parking space 5 of the carriage 10. In this exemplary embodiment, the can 2 assigned to this empty can parking space 5 is located on the transport device 22, which feeds the can 2 to the machine 20. The can transport vehicle 3 registers via a signal transmitter 31 with a corresponding sensor 32 of the machine 20. The can transport vehicle 3 is signaled via this signal transmitter 31 and sensor 32 whether a can change between the can transport vehicle 3 and the carriage 10 can be carried out. In the event that a transport operation is currently being carried out via the transport device 22, the can change is not released.

When approval has been given, the carriage 10 is moved according to FIG. 6b by a can parking space. As a result, the empty can 1 of the can transport vehicle 3 faces the free can parking space 5 of the carriage 10. The can change takes place in this position according to FIG. 6c. The empty can 1 of the can transport vehicle 3 is pushed onto the carriage 10, while the first full can 2 of the carriage 10 is moved onto the can transport vehicle 3. After this can change, the free can parking space on the carriage 10 is again opposite the transport device 22 and is ready for receiving the just filled can on the machine 20.

The exemplary embodiment according to FIGS. 6a-c shows a carriage 10 which is moved back and forth in the sliding area without guides 23. To protect against mechanical influences

REPLACEMENT LEAF On the carriage, guide rollers 27 are arranged on the magazine, which grip around the spar 11 of the carriage 10. This results in an exact guidance of the carriage 10.

It is common to all of the exemplary embodiments that the hub transport vehicle 3 moves so close to the carriage 10 that the gripping devices 30, 30 'are able to dispense cans on the carriage 10 or to pick them up from the carriage 10. The can transport vehicle 3 is moved towards the carriage 10 in such a way that the empty can 1 transported on the can transport vehicle 3 is located on the can parking space of the vehicle 3, which is on the side of the empty cans 1 of the carriage 10. In this way, only a few movements of trolley 10 and vehicle 3 are required to carry out the can change and to bring the trolley 10 back into the receiving position for a just filled can. In any case, care must be taken to ensure that after the cans have been changed between the carriage 10 and the vehicle 3, the free can parking space 5 on the carriage 10 is between the empty and full cans. By maintaining this order, it is always possible to advantageously change the can according to the same principle. The principle according to the invention is also inherent in the fact that the full can that is arranged directly next to the empty can parking space or next to the empty cans is always removed from the carriage 10. The last filled jug is thus the first to be removed from the carriage 10.

The invention of course relates not only to the long cans shown in the figures but also to round cans. The can change between the carriage 10 of the magazine and the can transport vehicle 3 can also take place independently of a machine 20. This means that a filled trolley 10 can be conveyed into a warehouse and is gradually emptied there by a can transport vehicle 3. Several carriages 10 can also be connected to form a train. In order to

REPLACEMENT LEAF it is possible that the pot magazine content is enlarged. The supply of can-emptying machines can also be carried out more rationally if these machines are started with several cars. This is particularly interesting when the jug-emptying machines are to be supplied completely with new cans, as can be the case, for example, when changing the part of rotor spinning machines. In this case, a large number of cans are conveyed to the rotor spinning machine and the cans can, for example, be exchanged section by section. It can be advantageous if the cans are also always on a carriage 10 on the rotor spinning machine. It is thus possible to remove a carriage 10 on the rotor spinning machine with empty or no longer required sliver from the rotor spinning machine and to replace it with a carriage 10 with new sliver in the cans.

Depending on the degree of automation of the system, it can be advantageous if the carriages 10 can be moved independently in the manner of a driverless transport system similar to the can transport vehicle 3. In this case, the carriages 10 move into a predetermined position after the desired filling state of the cans has been reached and clear the magazine on the machine 20 for a new carriage 10.

FIGS. 7a-7c show an exchange process for a full carriage 10. According to FIG. 7, the can transport vehicle 3 is positioned next to the carriage 10. The position is advantageously such that the free can parking space 5 of the can transport vehicle 3 faces a full can 2 of the carriage 10. A full can 2 is then taken from the carriage 10 onto the can transport vehicle 3. By moving the carriage 10 according to FIG. 7c in the direction of the empty can 1 of the can transport vehicle 3, the free can parking space 5 of the carriage 10 is brought into a receiving position. The empty can 1 is then dispensed from the carriage 3 and placed on the pitcher of the car 10. If necessary, the trolley 10 is then brought into a position (not shown), from which either the empty can 1 can be brought to be refilled or the full cans 2 can be made available for collection by another can transport vehicle 3.

A device is shown schematically in FIG. 8 immediately before the can changing process. In this exemplary embodiment, a free can parking space is provided on the can transport vehicle 3. The can transport vehicle 3 has a total of four can parking spaces, with three can parking spaces being occupied by empty cans 1. The can transport vehicle 3 is located at the stop at which it is connected to the control for the movement of the carriage 10 by means of the communication means 31, 32, which are designed as light barriers. The light barriers 31, 32 are each equipped with a receiver and a transmitter, so that signals can be exchanged for further actions. During the entire can changing process, the can transport vehicle 3 stops at this stop and can advantageously continuously exchange signals with the control for the carriage movement. The control for the carriage movement of the carriage 10 designed as a magazine acts on the friction wheel drive 24, which moves the carriage 10 back and forth in the double arrow direction and stops in the required can transfer position. Empty cans 1 and full cans 2 are arranged on the carriage 10.

According to the advantageous embodiment of the invention shown, the can transport vehicle 3 transports a plurality of cannons. In order to have a free parking space for the empty can to be replaced at the transport destination of the can transport vehicle 3, the vehicle 3 shown is able to transport three cans. The control for the car 10

REPLACEMENT LEAF checks the cans arranged on the trolley 10 for their filling time and, in accordance with the available transport capacity of three cans of the vehicle 3, selects the three oldest cans 2 for transfer from the trolley 10 to the vehicle 3. The position of the carriage 10 shown in FIG. 8 is such that the full can 2, which faces the free can parking space on the vehicle 3, is one of the three oldest filled cans 2. After this filled can 2 has been transferred to the vehicle 3, the carriage 10 is cycled further to transfer the empty can 1 of the vehicle 3 to the vacated parking space of the carriage 10. The carriage 10 is then cycled again until the as next achievable full can of the previously selected three oldest full cans faces the empty can parking space of vehicle 3. Subsequently, the full can 2 is again transferred to the vehicle 3. The procedure is accordingly continued until the three oldest cans have been transferred to the vehicle 3. The fourth full can 2 originally located on the carriage 10 is registered as the oldest can now during the next can changing operation and is provided for the change.

The decisive factor with this changing principle is that it is not the oldest can that is changed first, but that the number of cans to be changed is always the one that can be reached first. This results in considerably shorter changeover times, since the carriage 10 only has to be moved by short distances. Another advantage of this changing method is that the total possible displacement of the carriage 10 can be reduced. By the method described above, it is not necessary that the can located in FIG. 8 on the extreme right outside on the carriage 10 has to be allocated to the can parking space located on the extreme left on the vehicle 3. The same applies to the extreme left can parking space of the car 10 with respect to the rightmost can parking space of the vehicle 3.

REPLACEMENT LEAF at least two pitches can be moved less far. The reduced total displacement of the carriage 10 thus results in a faster change process.

The communication of the two light barriers 31 and 32 is described below as an example. Each of the light barriers can generate a low signal and a high signal, which is recognized by the corresponding light barrier. If the device is arranged on a line in which cans are filled, the light barrier 31 is in the "low" state while the empty cans are removed from the car 10, filled under the line and then back onto the car 10 can be pushed back. When the can transport vehicle 3 has arrived at the stop and is positioned, the light barrier 32 indicates by a high signal that it is requesting a can change. The control, which has received this request signal from the receiver of the light barrier 31, positions the carriage 10 such that one of the oldest full cans 2 to be transferred faces the free space on the can transport vehicle 3. It is calculated which of the oldest cans can be transferred to the free space of the can transport vehicle 3, taking into account the shortest displacement paths and possibly also whether a specific can parking space on the carriage 10 corresponds to a specific can storage space on the can transport vehicle 3 is assignable. The next can 2 to be transferred is often the can 2 standing next to the previously transferred can 2, viewed in the direction of travel of the can transport vehicle.

When the corresponding change position of the carriage 10 is reached, the can change is released. This release is effected by a high signal from the light barrier 31. When the full can is changed from the carriage 10 to the vehicle 3, the sensor design of the light barrier 32 is set to "low". As soon as the can 2 has been taken over, the end of the change process

REPLACEMENT LEAF ges indicated by a high signal from light barrier 32. The signal of the light barrier 31 is then set to "low" again and the carriage 10 is shifted by one position to transfer the empty cans to the vacant position on the carriage 10. The signal display of the light barriers 31 and 32 takes place in an analog manner when the empty cans are transferred.

The signals from the light barriers 31 and 32 ensure that the can change from the carriage 10 to the vehicle 3 and vice versa is not interrupted by a can change on the route. This interruption could lead to a delay and malfunction of the can change.

The illustrated invention is not limited to a magazine on a sliver-producing machine, but can also be made from a bearing which is independent of the sliver-producing machine. Here, the warehouse would be equipped with movable carriages 10 which, after being emptied, would be replaced by carriages 10 with full cans 2. The invention is not restricted to the exemplary embodiments described.
