Problems to be solved by the prior art and the invention
In a known method (WO 91/18135), an empty can store and a full can store are arranged one after the other, with an intermediate space for one can between the two can stores. At right angles to the can storage, this space communicates with the area of the filling head of the drawing machine through a continuous can transfer device consisting of chains and rollers. In operation, empty cans are transported from the empty can storage to the intermediate space and then continuously through the can transport means to the area of the filling head where the sliver is filled, and then the same can transport means in the opposite direction. And return to the intermediate space and from there carry it to the full canister. This method is time consuming in terms of can replacement in the area of the can storage. In particular, it is difficult for the can motion to have to turn at right angles between the can storage and the can transport means. For this purpose, the transport belt or the transport chain and the transport chain of the can storage are not tilted when transitioning from the can storage into the area of the transport chain or from the area of the transport chain to the can storage. At the transition between, a filling member is provided which fills the intermediate space. In doing so, furthermore, the known devices are costly, especially if the implementation of the method described above requires structural measures.

【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a drawing machine 1, for example, a high-performance drawing machine HS900 manufactured by Trutschler. Eight cans 3 are sent from the card (not shown) to the sliver guide table 2. In the illustrated embodiment, eight slivers 5 taken out of the can 3 are supplied to the drawing machine head 4. The thickness of the sliver to be discharged corresponds to the thickness of the sliver supplied individually. The sliver is guided above the sliver guide table 2. The newly formed sliver 6 (see FIG. 2) is filled in the can 8 by a filling head (funnel wheel or coiler plate) 7 which is a part of the drawing machine 1. After the cans 8 have been filled, they leave the filling head 7. Next, the can 8 is supplied by a can storage unit 12 and a can transport cart (not shown) of an open-end spinning machine (not shown).
[0007]
FIG. 2 shows the filling station with the can 8 having a longitudinal section in the filling position. The sliver 6 is supplied to the can 8 through a filling head 7. For the sake of clarity, the sliver 6 is shown only in a short part. The filling head 7 is fixed to a frame (not shown in detail) and rotatably supported. After the sliver 6 has been discharged from the drawing machine 1 to the calendar rollers, it is supplied to the filling head 7 through the two calendar rollers in a known manner. The diameter of the filling head 7 substantially corresponds to the width of the can 8 on the narrow side. Kens is on the carriage 9. During the filling operation, the reciprocating movement in the directions of arrows A and B is transmitted to the carriage 9 on which the can 8 is placed by the moving device 10. In doing so, the can moves the entire length below the filling head 7. A moving device 10 is provided for transmitting the reciprocating motion. This reciprocation extends over the filling stroke a (see FIG. 2). The can 8 is at one end of the filling stroke a as shown by the solid line, and the can 8 'is at the other end of the filling stroke a as shown by the dashed line. The moving device 10 is driven by an electric motor 11 whose rotation speed is controlled. A can storage unit 12 consisting of an empty can storage unit 12a for the empty can 8a and a full can storage unit 12b for a full can 8b filled with the sliver 6 exists in parallel with the long side of the drawing machine 1. Seen in the direction of movement (arrows C, D), there is an intermediate space 12c between the last empty can 8a and the first full can 8b. The empty can 8a or the full can 8b is on the conveyor belt 13. The conveyor belt 13 rotates endlessly around guide rollers 13a and 13b, and is driven by an electric motor 14.
[0008]
During operation, the sliver 6 is discharged from the filling head 7 and accommodated in a ring shape, and the can 8 reciprocates during this filling operation. At this time, the empty can 8a moves from the empty can storage unit 12a to the intermediate space 12c between the empty can 8a and the full can 8b before the filling operation, and is sent to the filling position therefrom. At this filling position, the can 8 is filled with the sliver 6, and after the filling operation, the filled can 8 is sent from the filling position to the intermediate space 12c between the empty can 8a and the full can 8b, from which the full can is stored, for example. To the vessel 12b . At this time, as a transport means, there is a moving device 10 with a carriage 9 between the filling position and the empty can storage device and the full can storage device. The transport means is arranged at right angles to the can storage device 12. The transport means sends the can 8 to the filling head 7 and returns it from the filling head 7. A reloading device 15 is provided for reloading the empty cans 8a from the intermediate space 12c to the carriage 9 before the filling operation, and reloading the full cans 8b from the transport means to the intermediate space 12c after the filling operation. In FIG. 2, the can 8 reciprocates in the filling stroke a in the directions of arrows A and B at the filling position below the filling head 7. In the transport step b, the empty can 8a moves from the can storage unit 12 to the filling position, or the full can 8b moves from the filling position to the can storage unit 12.
[0009]
In FIG. 3, the empty can storage unit 12a and the full can storage unit 12b form a common can storage unit 12 as a constituent unit. The can storage unit 12 has a common continuous transport belt 13 that rotates around guide rollers 13a and 13b endlessly in the directions of arrows E and F. Feeding projections 13c (FIG. 1) of the cans 8a and 8b are attached to the transport belt 13 in a direction transverse to the traveling directions C and D. The guide roller 13b is driven by the electric motor 14. The overall height of the conveyor belt 13 is small.
[0010]
FIG. 4 shows the can reloading device 15. Cans transfer device 15 has a compact tension arms 15a, compression and tension arms 15a has a direction move possible compact tension arm 15a of the arrows I and K with compact tension member 15b provided thereon ing. The compression / tension arm 15a is driven by, for example, an electric motor 16. Pneumatic pistons can also be used.
In FIG. 5, the moving device 10 has a toothed belt 17, on which a mounting plate 18 for the carriage 9 is fixed. An electric motor 11, for example, a reversible motor, is connected to a shaft end 19 for driving a toothed belt guide roller (not shown). The sliding member is denoted by reference numeral 20 and the guide in the linear unit is denoted by reference numeral 21.
[0011]
In FIG. 6, a flat can 8 is mounted on a carriage 9 in a vertical direction. The carriage 9 has a slide guide 22 surrounding the guide rod 23 on the lower side. The guide rod 23 is supported on a block 24. The other guide rod 23 'is formed as a slide track, on which the carriage 9 is guided by the guide 25 and slides.
[0012]
In FIG. 7, an electronic control unit, for example, a microcomputer 26 is provided, and the electric motor 11 is connected to the electronic control unit 27 via a motor adjusting device 27. An electric motor 11, for example a DC servomotor or an AC servomotor, is connected to a motor control 27 via a speed detector 28. The electric motor 11 is connected to a microcomputer 26 via a displacement sensor 29, for example, an incremental displacement sensor. The microcomputer 26 further comprises a terminal 30, a sensor 31 and an actuator 32, a drive 16 for the can reloading device 15, a drive 14 for the can storage 12, and measurement control elements for controlling and adjusting the drawing machine 1. It is connected.
[0013]
The displacement sensor 29 informs the microcomputer 26 of the current position of the can 8 to be filled. The length of the travel a during which the can 8 moves during the filling operation is structurally limited and is specified by the program to the microcomputer 26 (for example, turning points I = zero and II = 100). As long as the can 8 is not completely filled, it always reciprocates at a predetermined speed v between the two end points (I and II) of the stroke a. As soon as the filling sensor 31 confirms that the maximum filling has been reached, the can 8 slides past the end point II to the point III. From there the cans 8 are carried laterally and a new empty can 8a is thrown in at point III. The empty can 8a is captured and moves to the area of the travel a. Here, a filling operation is newly started.
[0014]
The speed v at which the cans 8 reciprocate between the end points (I and II) of the stroke a is variable and can be specified to the motor control device 27 by the microcomputer 26 on demand. In particular, just before reaching the end point, braking can be performed according to a programmable function. Then, when the end point is reached, the direction of motion is changed and accelerated according to a programmable function (see FIGS. 8 (a) and 8 (b)). For example, the electric motor 11 can be constantly accelerated or decelerated. It may also be advantageous to appropriately correct the slivering overlap at the turning point by acceleration or deceleration. The speed v at which the cans 8 travel the stroke a during the filling operation depends on the feed speed of the machine (drawing machine 1) and is directly (electronically) synchronized therewith.
[0015]
The speed at which the can 8 moves in the transport stroke b can be adapted to the can filling of the sliver 6.
The moving device 10 can also move a carriage or the like instead of the carriage 9.
The present invention also includes an embodiment in which the moving device 10 moves the can 8 directly on a transport device such as a roller way.
