Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin exchange / conveyance system for a winding tube and a cup, which has a pallet on which the cup and the winding tube are mounted, and the pallet is specific to a winding machine or a spinning machine. Unique and provided with contact areas of the transport paths of both pallet types, in which contact areas of both pallet types can be arranged adjacently, in which at least one replacement device is provided. From a mixing section which is assigned and by which the tube sent from the winder is captured by the displacing device and is exchangeable between both pallet types and the contact area is common to both transport loops. The present invention relates to a type in which both pallet types are alternately arranged in this mixing section.

[0002]

It has been known for almost 20 years to mount cups and tubes on pallets for the purpose of their transport, in particular in order to avoid damage to the yarn layer above the cup and to automate the transport process. is there.

It is also known to directly connect a spinning machine and a winding machine using such a transport system. DE-OS 3235442 specification can be mentioned as an example. The specification discloses a spin-winder combination in which a pallet holding a cup or winding tube circulates in a closed loop between both machines.
In this case it is necessary to adapt both machines to a given pallet size. This uniform pallet size also fixes the use of transport systems. In particular, if the spinning machine manufacturer and the winding machine manufacturer do not match, different pallet sizes and pallet types will be used. In this case, the above-mentioned transport system cannot be used.

In the German patent application DE 39 19 525.2, a spinning machine and a winding machine are provided, in which separate conveying loops are provided for the spinning machine-specific pallet and the winding machine-specific pallet pallet. The compound machine has already been disclosed. Both transport loops described above have a contact area where both pallet species are placed adjacent to each other. This contact area has a displacement device for exchanging cups and tubes between different pallet types.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a bobbin exchanging and conveying system for a winding tube and a cup, which has a pallet on which the cup and the winding tube are mounted. The purpose is to enable quick and reliable replacement of the cup and the winding tube.

[0006]

SUMMARY OF THE INVENTION The object of the invention is to introduce a transfer loop for a pallet peculiar to a spinning machine, in which there is one mixing section in a bobbin exchanging and conveying system of the type mentioned at the beginning and at the outlet side. Limited by a section, these openings are open to the transport section at the same height level, which height level corresponds to the upper surface of the substrate of the winder-specific pallet in the mixing section. It was solved by being.

[0007]

The configuration of the mixing section in which both pallet types are interleaved ensures a very rapid and reliable exchange of cups and tubes between both pallet types. The separation of the two pallet species after the mixing and exchange process is carried out in a simple and likewise very reliable manner by arranging them on different planes. By exchanging the entrainment means for conveying the pallets specific to the winder by means of a form connection, the mixing section can be adjusted to different pallet sizes without great expense. In this case, the bobbin exchange / conveyance system is not only suitable for direct combination of both machines, but also
It is also suitable for flexible transport systems with transport trolleys, for example as disclosed in German patent application No. 3935672.2. In this case, the mixing section is arranged between the transport carriage and the closed transport system of the spinning or winding machine.

Advantageous embodiments of the invention are claimed in claims 2 to 14.
It is achieved by the features described above.

The shape-specific transport of the pallet, which is unique to the winder, enables precise positioning in the mixing zone. The staggering of both pallet types ensures that the spinning machine-specific pallets are correctly positioned between the winder-specific pallets.

In the mixing section, the cups or tubes are arranged when the steps of the insert mandrels of both pallet types, which serve as supports for the winding feet of the cup or winding, are arranged at approximately the same height. After replacement, they are each fitted over a completely new insert mandrel. In this case, it is advantageous if the bayonet mandrel is designed such that the cup or the tube is seated relatively firmly.

The feeding of the spinning machine-specific pallets between the winder-specific pallets, even if sufficiently quick and reliable, if a plurality of pallets are dammed on the supply belt. At least, a feed swivel lever can be provided for feeding the last pallet in which a large pushing force is no longer created due to lack of damming. However, this feed swing lever is necessary when the transport system is to be operated at high speed. Form-tightening of the feed swivel lever by the subsequent pallet guarantees an accurate kinematics.

Similarly, for a spinning machine-specific pallet, controlling the discharge member at the end of the mixing section against the force of the spring by form-locking tensioning provides the same advantages.

The alternating placement of both pallet types, in combination with the stepped transport path, allows a simple and reliable separation of both pallet types without the use of sensors.

The displacing device must be constructed in such a way that the cup or the winding tube can be lifted in the vertical direction so that the displacing can be carried out without trouble. In this case, the horizontal movement required for the replacement process can be carried out either by the replacement device itself or by the pallet itself, which is arranged under a lifted cup or tube. The first configuration is advantageous for a gripping device for gripping a cup or tube in the approximate center, while the second configuration is suitable for a displacement device for gripping the tip of a tube. The reason for this is that during rapid horizontal movement, a high moment of inertia occurs in the cup caught at the tip of the winding tube and in the winding tube.

Depending on the length of the mixing section and the number of gripping elements of the displacement device, larger cup groups or tube groups can be exchanged. This fact is particularly significant in the case of newer textile machines that require high power.

Since the pallet peculiar to the spinning machine is usually smaller than the pallet peculiar to the winder, the pallet peculiar to the winder is forcibly guided and the pallet peculiar to the spinning machine is interposed between the pallets peculiar to the winder. The introduction was described as a priority solution. However, this does not limit the present invention to this, and the present invention also includes forcibly guiding the pallet unique to the spinning machine and inserting it between the pallets unique to the winder.

[0017]

EXAMPLE A pallet 1 peculiar to a winder equipped with a winding tube 4 as shown in FIG.
Is supplied to the conveyance range of the chain 5 along. The conveyor belt 8 is deflected by the deflection roller 8 '. The pallet 1 is guided on the substrate along the transport path 7.

Pallet 1 for the transport range of chain 5
Is supplied by the conveying range of the chain 5 formed by the sprocket 5 '. Carrying members 6 mounted on the chain 5 at equal intervals project into the conveying path of the pallet 1 and pass through the conveying section 7 ', the mixing section 17 and the following conveying section 9'by means of a form connection. Transport to the transport path 9. For this purpose, the transport section is the transporter 6
Slit guides 7 ", 17 'and 9" to ensure passage of
have.

The chain 5 includes a sprocket 5 ', a sprocket 5 ", a tension roller 12 and a drive sprocket 11 in addition to the sprocket 5'.
Changed by and. Drive sprocket 11 is motor 1
Combined with 5. The motor 15 is controlled by a central control unit 16 via a control lead 15 '. A tension spring 13 is engaged with the tension roller 12, and the tension spring is fixed to the holding portion 14 at the other end. In this way the chain 5 is always kept taut.

On the supply side of the pallet 1 peculiar to the winding machine, the supply between the entraining members 6 of the chain 5 does not cause any problem, and is performed by the damming pressure of the pallet 1 conveyed by frictional connection on the conveyor belt 8. On the other hand, this pallet 1 is moved to the conveying path 9 by the carrier 6 at the end of the forced guiding section, the conveying section 9 ', where it is received by the conveying belt 10. The conveyor belt 10 is deflected by the deflection roller 10 '.

The pallet 1 forcibly guided in the transport section 7 ′ reaches the opening 18 of the transport path 20 through which the pallet 2 peculiar to the spinning machine is transported by the transport belt 21. In this case, the transport path 20 is arranged at least at a height level corresponding to the height level of the upper surface of the substrate of the pallet sent to the winder. The pallet 1 has a pedestal-shaped upper structure 1 '. The upper structure 1'forms an intermediate chamber into which the pallet 2 peculiar to the spinning machine can enter. This intermediate chamber is formed by the dimensions of the substrate of the pallet 1 peculiar to the winder, the dimensions of the driver 6 and the diameter of the pedestal-shaped upper structure 1 '. A pallet size specific to the spinning machine can easily be adapted by replacing the pedestal-shaped superstructure 1'when a pallet with a replaceable superstructure is used. Of course, it is also conceivable to mount removable rings of different dimensions on the pedestal-shaped upper structure 1 '. Such interchangeable rings or pallet superstructures can serve a variety of purposes, for example, to distinguish pallets for different sets of bobbins they carry.

The adaptation of the pallet 1 to different substrate diameters is achieved by exchanging the carrier 6. Of course, this usually requires replacement or adjustment of the pallet side guides described below.

In FIG. 1, an additional device for supplying the spinning machine-specific pallet 2 to the opening 18 is omitted.
This omission ensures that the conveyor belt 20 runs at high speed and feeds the pallet 2 between the pedestal-like superstructures 1'at a sufficient speed, or the chain 5 is moved in a timed manner. While introducing the most advanced pallet 2 between the pallets 1 peculiar to the winder, the chain is opened 1
Yes, if stopped at 8. Further, when a plurality of pallets 2 are dammed on the conveying path 20 at the opening 18, the damming pressure is so large as to be surely pushed into the mixing section 17 starting at the opening 18. You can also do it.

As will be described later, the pushing process of the pallet 2 is performed stepwise, so that the damming pressure generated on the conveying path 20 is sufficient even when the chain 5 is continuously moved at the time of supply. ..

In FIG. 1, the process of supplying the pallet 2 peculiar to the spinning machine at the opening 18 has just ended. Furthermore, in this case, the most advanced pallet 2 on the conveyor belt 20 is in contact with the pallet 2 already pushed in,
It is clear that the pallet has been pushed to the position shown. When the pallets 1 and 2 are further conveyed into the mixing zone 17, the most advanced pallet 2 on the conveyor belt 20 is already in the first step, the pedestal-like superstructure of the subsequent pallet 1 specific to the winder. It penetrates into the mixing section 17 until it contacts 1 '. The pallet 2 is then pushed along this pedestal-like superstructure 1'into the mixing zone 17 until it reaches the central position in the mixing zone 17 (see the preceding pallet in FIG. 1). Furthermore, in this case, the position at which the predetermined position in the mixing section 17 is completely reached is taken up in the last part of the pushing movement, for example by the rounded portion of the cover plate 40 shown in FIG. And can extend just behind the opening 18.

In the area of the mixing section 17, a displacement device, which will be described later, is arranged. The replacing device replaces the cup 3 and the winding tube 4 on another type of pallet adjacent to each other. Another opening 1 at the end of the mixing section 17
9 is provided and the opening 19 is arranged at the same height level as the opening 18. At the opening 19, a transport path 22 branches from the mixing section 17. The transport path 22 has a transport belt 23. The conveyor belt 23 returns the pallet 2 specific to the spinning machine to the spinning machine.

In order to discharge the pallet 2 peculiar to the spinning machine from the mixing section 17 to the conveying path 22, according to FIG. 1, a fluid cylinder 24, which serves as an ejector, is provided. The fluid cylinder 24 is connected to the central control unit 16 via a control conduit 24 '. The fluid cylinder 24 has a stick 25, and the stick 25 is arranged at a height corresponding to the transport path 22. The pallet 2 peculiar to the spinning machine is extruded from the mixing section 17 by this thrust rod 25 and supplied to the conveyor belt 23. Instead of being controlled by the central control unit 16, the control of the fluid cylinder 24 can also be effected by a switch not shown. The switch can be actuated by the incoming pallet 1 specific to the winder. This makes it possible to control this fluid cylinder 24 simply and with great precision.

Further, as can be seen from FIG. 1, the pallet 1 peculiar to the winding machine sent along the conveying path 7 is an empty winding tube 4.
While the pallet 1 holds the cup 3, the pallet 1 holds the cup 3 after leaving the mixing section 17. The pallet 2 peculiar to the spinning machine, which is sent from the spinning machine through the conveying path 20, initially holds the cup 3, while the mixing section 1
7, after the replacement is performed, the winding tube 4 is mounted on the pallet 2 peculiar to the spinning machine that is unloaded from the mixing section on the transport path 22. The details of the replacement process will be described below.

2 to 6 show three successive processes for the supply and the discharge of the pallet 2 peculiar to the spinning machine. In this case, a feed swivel lever 29 is used at the opening 18. The purpose of this supply swivel lever 29 is to help the pallet 2 peculiar to the spinning machine prepared on the transport path 20 to be rapidly supplied to the mixing section 17. When the chain 5 moves relatively quickly and continuously in the feed 1 discharge process, ie during the displacement process, the pushing force of the conveyor belt 21 or the pallet 2 dammed on it may be sufficient in some cases. It is not large and cannot guarantee a reliable and prompt supply. In this case, the feed swivel lever 29 is operated during the entire bobbin exchange process, that is, until the ring spinning machine is completely emptied.

Further alternatively, the supply turning lever 29
Can be operated only to supply the last pallet 2 specific to the spinning machine. This necessity arises because, when the number of pallets 2 that are dammed in the transport path 20 decreases, the sum of frictional forces on the transport belt 21, and thus the pushing force, decreases.

The supply turning lever 29 can turn about a turning center pin 30 arranged on the holding portion 31.
A torsion spring 30 is arranged around the turning center pin 30. One leg 36 of this torsion spring
Is attached to the holding portion 31, while the other leg portion 37
Acts on the supply swivel lever 29 (see FIG. 5). The spring legs 36 and 37 transmit clockwise torque to the supply turning lever 29. In FIG. 2, the supply turning lever 29
Is in the most swiveled position in this direction after supplying 17 pallets 2. This is because the pallet 1 peculiar to the winder, which is adjacent to the pallet 2 peculiar to the supplied spinning machine and is located upstream in the transport direction, has passed the deviation curve 29 'of the supply turning lever. .. Already at this point, the subsequent pallet 1 peculiar to the winder reaches the deflection curve 29 '.

As can be seen from FIG. 3, when the chain 5 continues to run, and when the pallet 1 peculiar to the winder further approaches, the supply turning lever 29 resists the spring force. To turn counterclockwise. In order to prevent the next stand-by pallet 2 peculiar to the spinning machine from being moved away from the opening 18 by a predetermined value again at the time of this return turning, the supply turning lever 29 has a tilting nose 32 at its tip. is doing. The tilting nose 32 is attached to the supply turning lever 29 via a turning center pin 39. A torsion spring having spring legs 33 and 34 normally holds the tilting nose 32 in a straight extended position as can be seen in FIGS. In this straight extended position the tilting nose abuts the stopper edge 35 of the feed swivel lever 29 with a straight trailing edge. This limits the tilting nose from turning in this direction.

As can be seen from FIG. 3, when the supply turning lever 29 returns, the tilting nose 32 is swung clockwise against the spring force, whereby the tilting nose 32 stands by on the conveyor belt 21. You can easily pass through the existing pallet 2. In this case, it is advantageous that the spring force is not too large and the pallet 2 is not pushed back against the transport direction of the transport belt 21. However, the spring force must be sufficient to return it to its starting position after the pallet 2 has passed the tilting nose 32. Since the tilting nose 32 comes into contact with the stopper edge 35 during the working period of the supply swiveling lever 29, that is, when the pallet 2 is supplied to the mixing section 17, the tilting nose 32 cannot swivel rearward. As a result, a sufficient pushing force is exerted on the pallet 2 to be supplied.

As can be seen from FIG. 6, in the pallet 1 peculiar to the winder, which comes into contact with the deviation curve 29 'of the supply swivel lever 29 during the above-described turning process, the supply swivel lever 29 has a maximum counterclockwise offset position. It is transported to a position where it can be reached by a purely geometrical connection.

In the operation process shown in FIG. 6, the operation process shown in FIG. 2 is performed again. The spinning-specific pallet 1 has passed the deflection curve 29 ', which causes the spring with the spring legs 36 and 37 to feed the swivel lever 2.
Pivot 9 to the position shown in FIG. At this turning point, the pedestal-shaped upper structure 1'of the two pallets 1 peculiar to the winder is controlled by controlling the shape of the feed turning lever 29.
The gap formed by is precisely tuned at the time it reaches the opening 18. This precise tuning makes it possible to drive the chain 5 at a relatively high speed. This results in high productivity of the entire cup changing process.

With respect to the opening 19, the discharge lever 26 can also turn about the turning center pin 28 about the turning center axis. The turning center pin 28 is supported by the holding portion 27. A torsion spring 38 is engaged with the discharge lever 26, and the torsion spring 38 is fixed to the holding portion 27 by the other spring leg portion (see also FIG. 4). This torsion spring acts counterclockwise. As a result, the ejection lever 26 is always spring-loaded towards the opening 19.
In FIG. 2, the discharge lever 26 has just lost contact with the base of the pallet 1 peculiar to the winder. As a result, as shown in FIG. 3, the pallet 2 peculiar to the spinning machine is discharged to the transport path 22, and on the transport path 22, the pallet 2 is supplied to the spinning machine again by the transport belt 23. However, from FIG. 3, after discharging the pallet 2 peculiar to the spinning machine from the mixing section 17, the next pallet peculiar to the spinning machine sent by the chain 5 is the pedestal-shaped upper structure 1 ′ and the discharging lever 26. It can be seen that it has already begun to turn clockwise again against the force of the torsion spring 38. FIG. 6 shows the operation after the turning. However, in this case, the release lever 2
It is still in contact with the pedestal-shaped upper structure 1'of the pallet 1 mentioned above, which is specific to the 6-winder. This operation is followed again by the operation shown in FIG. 2 and already described. As can be seen from FIGS. 2 to 6 and FIGS. 14 and 15, stepped guide edges 40 and 41 are provided for the winder-specific pallet 1 or the spinning machine-specific pallet 2, respectively. .. The guide edges 40 are spaced from one another so that the respective pallets can be guided on the peripheral surface of the base body. A cover plate 40 'for connecting the two guide plates 40, 41 is arranged between the guide plates 40, 41 extending substantially vertically. Another cover plate 40 directed inward is connected to the guide plate 41. Cover plate 4
0'and 42 are provided, inter alia, for the cup and tube replacement process in order to reliably guide both pallet species in the mixing section. This cover plate receives vertical forces, for example when pulling out cups and tubes. The cover plate 40 ′ also serves for guiding the winder-specific pallet 1 outside the mixing section 17 and in particular for preventing it from tilting.

Guide edge 4 as can be seen from FIGS.
0 is consistent and extends beyond the mixing zone 17 on both sides. In this way, the winder-specific pallets are always guided by form connections, so that they always assume a defined position. Especially in the region of the openings 18 and 19, a vertical guide plate 40 is also present when the winder-specific pallet 1 is used for the transmission of movement by means of a form connection to the discharge lever 26 and the supply swivel lever 29. Is meaningful.

While the upper surface of the substrate of the pallet 1 peculiar to the winder forms the support surface for the pallet 2 peculiar to the spinning machine in the mixing section 17, the guide plate 40 has a cover plate 40 '. A support plate 40 "is connected facing downwards. The support plate 40" serves as a support for the pallet 1 peculiar to the winder, and guide slits or slit-shaped passage openings 17 'are provided in the carrier 6 of the chain 5. (FIGS. 14 and 15).

Next, the process of replacing the cup 3 and the winding tube 4 with another pallet type will be described with reference to FIGS. 7, 8, 9, 10, and 11 based on an embodiment of the present invention.

In FIG. 7, the starting point of the replacement process is shown. In this case, the replacement device 43 is first shown schematically. Figure 7 shows the most advanced position when viewed in the transport direction.
In, there is an empty winder-specific pallet 1 specific to the winder. The displacing device 13 has already been lowered and is holding the cup 3 and the winding tube 4 at the tip of the winding tube. As can be seen in FIG. 8, the cup 3 and the winding tube 4 which have been grasped are drawn up onto the insertion mandrels of both pallet types. In this case, withdrawal is only necessary up to the height at which the winding foot is located above an imaginary plane passing through the tips of the insert mandrels of both pallet types.

As can be seen from FIG. 9, the chain 5 is returned by half a pitch, whereby the pulled-up cup 3 and winding tube 4 are positioned on various adjacent pallets.
The displacing device 43 does not have to perform a horizontal movement for this purpose. FIG. 10 shows the steps of lowering and inserting the cup 3 and the winding tube 4 onto various pallets, respectively. This results in an empty pallet 1 peculiar to the winder at the end of the replacement section. Then, the replacing device 43 separates the cup and the winding tube again, and returns to the upper position, that is, the standby position. In FIG. 11, the position where the pallet has been advanced by half a pitch has already been shown. This allows opening 1
Supply and discharge of the pallet 2 peculiar to the spinning machine in 8 and 19 are started. At this time, the chain 5 is moved in the normal conveying direction until the empty pallet 1 peculiar to the winder reaches the position shown in FIG.

The coding of all these movements is done via the central control unit 16. The control unit 16 drives the chain 5 in the normal conveying direction until it reaches the position of FIG. This can be controlled very precisely by the chain 25 driven by the drive sprocket 11. Drive sprocket 1
One rotation of 1 makes it possible to carry one pitch corresponding to the interval of the carrying members 6. Chain 5 in the normal transport direction
The continuation of the movement of is adapted to the size of the displacement device 43, that is, the number of gripping devices. FIG. 12 is a conceptual plan view of FIG.

FIG. 13 shows an embodiment of the replacement device 43 usable according to the invention. 14 and 15 are detailed views as side views for clarifying the gripping mechanism.

The illustration in FIG. 13 corresponds to the steps of the replacement process shown in FIG. The displacing device 43 is attached to the machine frame 60 via holders 49 and 49 '. A crossbeam 50 is mounted on both holding bodies, to which crosspiece 50 a holding part for a gripper 44 is fixed. If the displacing device 43 is to be adapted to different pallet dimensions, it is advantageous, although not shown, for the holding part 51 to be detachably connected to the cross beam 50, for example via a clamp connection. There is.

The holding part 51 has two legs 51 'and 51 ". The legs 51' and 51" are arranged in parallel.
The switch rods 52 and 53 are guided so as to be movable in the longitudinal direction. A gripper 44 is fixed to the switch rods 52 and 53. Therefore, the switch rods 52 and 53 are used to directly transmit the vertical movement of the gripper 44. A switch rail 54 is provided to transmit this movement. The switch rail 54 has contacts for all switch rods 52 of the individual grippers 44. In this case, the switch rods 52 are connected to the legs 5 respectively.
The force of the compression spring 57 supported by 1 ″ keeps the state in contact with the switch rail 54 via the collar 52 ′.
The switch rail 54 is fixed to the thrust rods 48 and 48 'of the fluid cylinders 46 and 46'. This fluid cylinder is connected to a switching valve 67, which is connected to the central control unit 16 via a control line 67 '.

In the state shown in FIGS. 13, 14 and 15, the projecting rod 48 or 48 'is started. As a result, the gripper 44 is at the lowest position. When fluid cylinders 46 and 46 'are actuated by valve 67,
The butt rods 48 and 48 'are driven, which causes the spring 57 to move the switch rod 52 upwards and the gripper 44.
Are moved vertically.

The operation of the clamp device acting on the clamp lever 53 can be performed independently of the lifting movement of the gripper 44. To this end, fluid cylinders 45, 45 'are provided. The fluid cylinders 45, 45 'are valves 68
Controlled through. The valve 68 is also connected to the central control unit 16 via a control line 68 '. The fluid cylinders 45, 45 'have taps 47, 47', to which switch rails 55 common to all grippers are fixed. This switch rail 55 acts on the switch bar 53 of the individual grippers which actuate the clamping lever 63. The clamp lever 63 is pivotally supported by the gripper 44 via a pin 64. The clamp lever 63 is connected to the switch rod 53 via the turning center pin 62. In the clamped state (FIG. 14), the clamp lever 63 is rotated counterclockwise about the pin 64. The clamping force is generated by the push spring 59. The push spring 59 is likewise supported on the leg 5 ″ and acts on the collar 58 of the switch rod 53. Another collar 61 serves to limit the reciprocating movement of the switch rod 53. If the winding tube is not arranged in the receiving opening 65, the pushing spring 59 moves the switch rod 53 further upward than that shown in Fig. 14. In this case, the collar 61 contacts the stopper 66 of the gripper 44. Contact.

As shown in FIG. 15, the valve 68 is actuated and the thrust rods 47, 47 'are moved to the liquid cylinders 45, 45'.
When driven out of, the switch rail 55 pushes the switch rod 53 downward against the force of the push spring 59. As a result, the clamp lever 63 is swung clockwise around the pin 64 to release the ends of the respective winding tubes.

A displacement device as described in which the tip of the winding tube is clamped from the outside and, alternatively, a gripping mechanism is introduced into the winding tube,
There, it is also possible to use a displacement device, for example loaded with a pressure medium and thereby supported on the inner wall of the winding tube.
The alternative use of this displacing device is particularly advantageous when displacing a cup in which the winding thread reaches the upper winding edge.

Another embodiment of the replacement device is shown in FIGS.
It is illustrated up to 9. The difference between this displacing device and the displacing devices described thus far is that the cup or tube is gripped laterally approximately at the center of the length of the cup or tube. Since this gripping position corresponds to the center of gravity of the cup or the winding tube, little or no moment of inertia occurs during horizontal displacement. As a result, such a displacement device is also reached in order to transfer rapid horizontal movements to the cup and the winding without problems. Therefore, returning the chain 5 by half a pitch during the replacement process can be substituted by advancing the replacement device in the transport direction. This does not require high clamping forces, unlike the replacement devices described so far. This is because there is almost no need to overcome the moment of inertia as already explained. With such a displacement device it is possible to reduce the wear of the chain 5 driven in only one direction, with only interruptions during the displacement process.

A lateral beam 78 is fixed to the bitch 69, and fluid cylinders 79 and 80 for the cup 3 and the winding tube 4 are held in the lateral beam 78. Like the holding part 51, the fluid cylinders 79 and 80 can be detachably or movably fixed to the cross beam. For this purpose, for example, the cross beam 78 can have a slot, not shown, through which the fixing screws for the fluid cylinders 79, 80 project.

A gripper 81 of the cup 3 and a gripper 82 of the winding tube 4 are attached to the piston rods of the fluid cylinders 79 and 80. These grippers can have a V-shaped gripping surface with a rubber lining 83 as shown in FIG.

The strokes of the gripper 81 for the cup 3 and the gripper 82 of the winding tube 4 can be selected equally. In this case, as shown in FIG. 17, the fluid cylinder 7
9 and 80 have the same size. However, the magnitude of the stroke is such that, in the closed position, the gripper 82, which forms the smaller opening for the winding tube 4, does not interfere with the transport of the cup 3 along the mixing section 17 in the open position. You can also choose to move it outwards. However, the stroke of the gripper 82 can be selected larger than that of the gripper 81. The fluid cylinders 79, 80 can advantageously also be controlled via a common valve. The lead 79 'in FIG. 18 merely indicates that the fluid cylinder is controlled by the central control unit 16. Illustration of the valve has been omitted.

Bridge 69 holding all gripping devices
Is fixed to the piston rod 71. The piston rod itself is movable within the fluid cylinder 70. The fluid cylinder 70 is likewise controlled by the central control unit 16 via a control lead 70 '. The vertical movement of all grippers is performed by actuation of the fluid cylinder.

To ensure the horizontal movement of the displacement device, a fluid cylinder 70 is mounted on the running club 74. The traveling club 74 can travel on rails 75 by traveling rollers 73. The traveling rollers 73 are driven by a common shaft 74. In order to achieve accurate positioning of the traveling club 72, the traveling roller 73 and the rail 85 may have teeth that mesh with each other. Although not shown, it is possible to mount a stopper for the running club 72 on the rail 75 to fix both dead points of the movement of the running club 72. Both shafts 74 for running rollers 73
Is driven by a motor 76 via a transmission 77. This motor is also operated by the central control unit 16 via the control conductor 76 '. The movement of the running club 74 can be controlled in very different ways. For example, the running club can be fixed to both ends of the chain. The chain is deflected through sprockets located outside the range of motion of the running club. In this case, one of the sprockets can likewise be connected to the drive. However, since the transmission device of such a motion component is a device known in the field of mechanical engineering, further modification of the modified embodiment will be omitted.
