Description

[Detailed description of the invention] Industrial application field The present invention relates to a spinning machine in the front process and a spinning machine in the downstream process, such as a first drawing machine and a second drawing machine, or a card and a drawing machine using a can continuous exchange device. This invention relates to a sliver take-out device that takes out the sliver from a full can containing the sliver spun by a spinning machine in the previous step when continuous spinning is performed by connecting the spinning machines.

Conventional technology Various devices have been proposed for the sliver extraction device, and the present applicant has also proposed
The patent application has been filed for a sliver feeding device disclosed in the above publication. In this conventional technology, a full can is placed on a turntable installed at a predetermined position in a can circulation passage of a continuous can exchange device installed between a first drawing machine in the front process and a second drawing machine in the post process. is placed and rotated, and the cut end of the sliver hanging down is sucked by a suction nozzle placed close to the can to extract the sliver.

Problems that the invention attempts to solve As is well known, a full can containing sliver is
The stored sliver protrudes from the upper end surface of the can to a considerable extent, and the cut end of the sliver hangs down from the top surface of the protruding sliver, but the amount of protrusion and the length of the cut end vary and are not constant. . Therefore, in order to reliably extract the sliver using the above-mentioned conventional device, it is necessary to perform suction using the protruding part of the sliver that protrudes from the can. It has the disadvantage of being sucked and causing fuzz on the sliver.

Means for Solving the Problems The present invention improves the drawbacks of the conventional device described above, and is as follows. When a full can containing sliver, which has a path for transferring cans between a spinning machine in the preceding process and a spinning machine in the subsequent process, is placed on a can rotating device provided at a predetermined sliver output device in the passage, First, the press device installed at that position operates,
The protruding portion of the can is pressed down to a level substantially flush with the upper end of the can, so that the cut end of the sliver hangs down along the outer circumferential surface of the can. Next, the sliver holder is brought close to the upper end of the outer circumferential surface of the can, and the can rotating device is operated to rotate the can, and the cut end hanging down on the outer periphery of the can is held by the sliver holder. This eliminates the drawbacks of the conventional device.

Embodiments The present application will be described in detail below with reference to drawings showing embodiments. In FIGS. 1 and 2, 1 is a first drawing machine that is a spinning machine in the front process, 2 is a second drawing machine that is a spinning machine in the back process, and the first and second drawing machines 1 and 2 are A can continuous exchange device 3 is disposed between them. The can continuous exchange device 3 has an elliptical shape as shown in the drawings, and has a circulation passage 5 for transferring the cans 4 clockwise in Fig. 1 as described in detail below. There are cans 4 divided as follows.

In FIG. 1, a delivery can 4A is disposed at the spinning position indicated by A, in which a cartridge wheel 6 provided in a circulation path 5 is mounted and rotates in a predetermined direction. The sliver 7 spun from the coiler that performs the spinning is stored therein. Next, B is the sliver exit position, and at this position, the full can 4B with the sliver 7 stored therein is sent out as described later. As shown in Fig. 4, the sliver 7 stored in
The cut end 7A of the sliver 7 protrudes from the upper end of the can 4 to a considerable extent and is cut when being fed from the spinning position A to the outlet position B, and the cut end 7A hangs down.
As mentioned above, the protrusion amount and the hanging length vary and are not constant. 4C is a plurality of feed cans arranged at the supply position C, and the number of feed cans 4C is the same as the number of doublings (5 in this embodiment). The sliver 7 drawn out from each feed can 4C has a so-called taper setup in which the amount is the maximum on the most upstream side in the moving direction of the feed can 4 and is gradually decreased to a predetermined amount so that it is the minimum on the downstream side. As shown in the figure, the polymer is polymerized via guide rollers 8 and the like, and then supplied to the drafting section 9 of the second drawing machine. Finally, 4D is an empty can placed at the standby position D. When the delivery can 4A at the spinning position A becomes full, the can is exchanged and sent to the spinning position A, where the sliver 7 is stored. . Furthermore, the above empty can 4D
It is necessary to provide at least one spare empty can 4S between the feed can 4C and the most downstream can 4 of the feed can 4C.

Next, a moving mechanism for moving each can 4 disposed in the circulation passage 5 by a predetermined amount at a desired time will be explained. 10 is an exchangeable arm,
They are fixed to hard shafts 11 that are pivoted to a can continuous exchange device so as to face the front of the spinning position A, and are mounted at equal intervals of 90 degrees, and on the can puller side are cans that have been moved. The hard shaft 11 is connected to the first drawing machine 1 through a suitable transmission means from the motor M1.
Intermittent rotation of 90 degrees per pitch is performed in response to a full can command from an equipped auto counter (not shown). 1
Reference numeral 3 denotes a roller conveyor, which is driven by a motor M3 through an appropriate transmission means, and rotates in substantially synchronization with the exchange arm 10 to move the feed can 4C and the spare empty can 4s, and its moving speed is equal to the exchange arm 10.
It is set to a slower speed.

Finally, three devices that form the gist of the present application will be explained. First of all, the can rotating device 14 is as follows. Reference numeral 15 denotes a turntable installed at the outlet position B, on which a full can 4B sent out from the spinning position A by can exchange is placed, and the motor M
2 allows for gentle rotation in the direction of the arrow in FIG. Next, the press device 16 is as follows. 20 is a sliver holding device 1 to be described later.
Press cylinder 19 attached to the mounting base 18 of 7
In the storage box, the full can 4B located at the exit position B
The press cylinder 19 and piston rod 21 are installed so as to directly face each other, and housed inside the press cylinder 19 and the piston rod 21.
It protrudes outside the box body from the top surface of the storage box 20. A guide rod 22 is attached to the upper end of the piston rod 21.
The press cylinder 19 is guided by the press cylinder 19 to move up and down by a predetermined stroke, and the above-mentioned full can 4B is
A press plate 23 is attached so as to cover the upper surface of the press plate 23. The stroke of the press cylinder 19 is such that when the piston rod 23 reaches its highest point, the press plate 23 is in contact with the uppermost surface of the protruding portion of the sliver 7 protruding from the full can 4B, as shown in FIG. Facing each other at intervals,
The projecting portion is set so as not to interfere with the press plate 23 when the full can 4B is sent out from the spinning position A to the outlet position B. Further, as shown in FIG. 5, the lowest end has a slight distance from the upper end of the full can 4B, and is set so that the two do not come into contact with each other.

Finally, the sliver holding device 17 will be explained. The sliver holding device 17 is attached to the top of a tower 24 provided on a base 18 approximately in the center of the can continuous exchange device 3, and includes a suction arm 25 and a suction head 2, which is exemplified as a sliver holder attached to the tip of the suction arm 25.
It consists of 6. Suction arm 25 is tower 2
The vertical movement device 27 and the rotation device 28 attached to the container 4 perform vertical and rotational movements, and this combined movement causes the suction head 26 at the tip to move between the upper outer circumferential surface 4BA of the full can 4B at the outlet position B and the second It reciprocates between the drafting section 9 of the drawing machine 2 and supplies the sliver 7 drawn out from the full can 4B to the second drawing machine 2. 3
0 is a detector consisting of a phototube or the like attached to the suction head 26, which detects the cut end 7A of the sliver 7 suctioned and held by the suction head 26.

As shown in Figure 1, the first and second drawing machines 1 and 2
Circulation passage 5 of can continuous exchange device 3 arranged between
The cans 4, each divided as described above, are placed at predetermined positions in the spinning machine to perform the spinning operation, and when the delivery can 4A at the spinning position A is full, the cans 4 are spun from the first drawing machine 1. An auto counter (not shown) that detects the amount of sliver 7 spun is activated, the first drawing machine 1 is stopped, and the can is exchanged as follows. That is, when the first drawing machine 1 is stopped by the above-mentioned full can command, the exchange arm 10 then makes one 90° movement and the roller conveyor 13 starts operating, and the full can ( In addition, this can is due to the previous can exchange.
The sliver has already been drawn out in the full can that has been sent to the outlet position, but the key point of this application, which is the feeding operation associated with can exchange, will be described in detail later. ) 4B is placed on the roller conveyor 13, and the full delivery can 4A, that is, the full can 4B, which is at the spinning position A, is transferred to the turntable 15 at the delivery position B.
Above, the empty cans 4D at the standby position D are placed on the candy can plate 6 at the spinning position A, and the spare empty cans 4S sent by the roller conveyor 13 are sent to the standby position D, respectively. On the other hand, the feed cage 4 placed on the roller conveyor 13
In C, 4 Kens move and 1 exchange arm is moved.
The full can 4B at outlet position B, which was sent out at speed 0, has a delivery speed of roller conveyor 1.
Since the feeding speed is set faster than the feeding speed of No. 3, it catches up with the most upstream side of the moving feed can 4C during feeding, and moves to the feeding position C by pushing it. When the cans 4 arranged in the circulation passage 5 as described above reach their respective predetermined positions,
The operation of the exchange arm 10 and the roller conveyor 13 is stopped, the can exchange is completed, and the can exchange is completed at the exit position B.
The full can 4B sent out from there becomes the feed can 4C on the most upstream side, and the feed can 4C that has been located on the most downstream side until now becomes a spare empty can 4S, and the two are exchanged.

Next, the operation of drawing out the sliver 7, which is the gist of the present application, is carried out as follows. When the full delivery can 4A at the spinning position A is replaced as described above, the sliver 7 stored in the can 4 is removed from the pressing part of the coiler plate while being pressed by the coiler plate at the spinning position A. As shown in FIG. 4, the can 4 swells up from the upper end to form a protrusion, and in this state there is a gap between the full can 4B sent to the outlet position B and the first drawing machine 1. The sliver 7 is still connected. Because of this, when the can exchange is completed and before the first drawing machine 1 resumes operation, the sliver 7 that is continuous between the outlet position B and the first drawing machine 1 is
It is well known that the cut end 7A of the cut sliver 7 hangs down along the protruding part as shown in FIG. The length of the cut end 7A varies and is not constant. Therefore, as described above, conventionally, when cutting out a full can, the projecting portion of the sliver 7 was used to ensure reliable cutting.

In the present application, when the sliver 7 is cut as described above, the press cylinder 19 of the press device 16 is activated to pull down the piston rod 21, and the press plate 23 located directly above the protruding portion fills the protruding portion. When the press plate 23 descends to the predetermined position described above, the press cylinder 19 stops, and the cut end 7A of the sliver 7 hangs down along the outer peripheral surface 4BA of the can 4B (Fig. 5). ). When the press cylinder 19 starts operating as described above, the sliver holding device 17 starts operating at approximately the same timing, and due to the combined movement of the vertical and pivoting devices 27 and 28, the sliver holding device 17 starts operating as shown in solid lines in FIGS. 1 and 2. The suction arm 25, which was in the standby position shown in FIG. and start suction.
Along with the above movement of the suction arm 25, a full can of 4
The turntable 15 on which B is placed starts to slowly rotate in the direction of the arrow in FIG. 1, and the sliver 7 is pressed down by the press plate 23.
The cut end 7 of the sliver 7 makes approximately one rotation.
A is suctioned and held on the metal surface 29 of the suction head 26, and when the cut end 7A of the suctioned and held sliver 7 is detected by the detector 30 attached to the suction head 26, the turntable 15 stops rotating. When the turntable 15 stops, the press cylinder 19 and suction arm 25 are moved up and down and rotated by devices 27 and 28.
operates in the opposite manner to the above, and the press plate 23
By returning to the state shown in the figure and also returning the suction arm 25 to the standby position, the sliver 7 is pulled out from the full can 4B and the sliver 7 is taken out.

Next, another embodiment of the device of the present application will be briefly described. In the above embodiment, the press plate 23
is fixedly provided on the piston rod 21, but if, for example, a suitable mounting arm is fixed to the piston rod 21 and rotatably pivoted to the mounting arm, the press plate 23 and the sliver 7 will be connected when the full can 4B rotates. This can prevent friction between the Moreover, instead of suction holding the sliver holder 26, the cut end 7A may be gripped by a gripper such as an open/close type gripper. Finally, can continuous exchange device 3
Other embodiments of the present invention and other embodiments of a full-can rotation device that replaces the turntable 15 will be described. In the can continuous exchange device 3 shown in the embodiment of the present invention, both the spinning machines in the front and rear processes are drawing machines, and the ratio is 1:1.
We have described the minimum necessary can continuous exchange device 3 in the case of connecting at a ratio of In 1988, Japanese Patent Application Publication No. 1983-
As disclosed in FIG. 1 of Publication No. 104932, a substantially U-shaped circulation passage 5 is formed with a bulging portion at the supply position C where the feed cage 4C is located, and the circulation passage 5
A press device 16 similar to the above embodiment may be attached to the outlet position B of the full can 4B set at a predetermined position.

Furthermore, the can rotating device 3 can be implemented using other embodiments as follows. As shown in part in FIG. 7, the outlet of a full can 4B is set at a predetermined position in the circulation passage 5 of the continuous can exchange device 3, which is substantially the same as that adopted in the above-mentioned Japanese Patent Application Laid-Open No. 62-104932. At position B, instead of the turntable 15, a plurality of rollers 115 are radially supported, and the rollers 1
15, the full can 4B is rotated.

Effects of the Invention As described above, according to the device of the present invention, in the sliver feeding operation when feeding a full can from a spinning machine in the previous process to a spinning machine in the subsequent process, the sliver protrudes from the upper end of the full can at the sliver feeding position. The sliver is pushed in by the press plate and the top surface of the sliver is positioned very close to the top of the can, so even if the length of the cut end of the sliver varies in length or short, the cut end of the sliver can be moved from the top of the can to the outer circumferential surface of the can. It can be positioned downward along the Since the cut end of the sliver is held by rotating the full can in this pressed state, only the cut end of the sliver can be securely held, and other sliver portions are not held inadvertently. In particular, when a suction type sliver holder is used, there is no risk of suctioning the sliver itself or causing damage to the sliver, such as creating fuzz, as in conventional unloading work. Since it is now possible to bring the sliver holder very close to the outer circumferential surface of the full can, the suction effect is increased and there are no suction errors. Further, since the sliver holder is provided with a holding detector for the cut end of the sliver, it is possible to accurately check whether the cutting end of the sliver has been picked out, and there is an effect that picking mistakes can be prevented.
