Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of pre-process machines that form a sliver and store it in a can, and a drawing machine that forms a sliver by doubling the sliver drawn from the plurality of cans. The present invention relates to a continuous spinning device which is connected to a post-process machine and in which the full cans of each pre-process machine are sequentially supplied to the post-process machine.

2. Description of the Related Art Conventional continuous spinning devices of this type are generally known as Japanese Patent Publication No. 38-2517.
As disclosed in Japanese Patent Publication No. 2 and Japanese Utility Model Publication No. 46-34341, a sliver carrying belt and a table are arranged on the upstream side (rear side) of the kneading machine, and a plurality of cards are provided along the belt and the table. A cotton machine or a carding machine is installed in parallel, and the sliver spun from each carding machine or the like is directly placed on a belt or a table and supplied to the draft zone of the kneading machine. Further, in a combination of a carding machine and a kneading machine, there is a slider feeding device which automatically conveys a full can containing the sliver to the kneading machine by the carding machine.
No. 220 is disclosed.

Problems to be Solved by the Invention In the case of the device described in Japanese Patent Publication No. 38-25172, etc., the number of carding machines is the same as the number of doubling of the sliver, and the cost is increased if the number of doubling is increased. In addition to being higher, the spinning ability of the carding machine is larger than that of the drawing machine,
The spinning speed of the carding machine has to be reduced to a speed considerably lower than the capacity, which is very uneconomical. For example, a spinning machine has a spinning capacity of 600 m / min, and a carding machine has a spinning capacity of 15
At 0 m / min, with a sliver doubling number of 8, the spinning speed of the carding machine had to be reduced to 50% of its capacity.

On the other hand, in the case of the device disclosed in Japanese Examined Patent Publication No. 39-16220, the full can containing the sliver in the carding machine process is automatically conveyed to the kneading machine process and the kneading machine process is completed. Since the sliver is pulled out from the can and supplied, there is no problem like the conventional continuous spinning device described above, but in this device, a full can can be automatically conveyed, but the sliver can be fed to the kneading machine. However, there is a problem in practical use that the cost is high and the equipment cost is high because a large amount of cans are required.

Means for Solving Problems The present invention solves the above-mentioned problems, and the empty can is automatically conveyed between the pre-process machine and the post-process machine, and the sliver is automatically supplied to the post-process machine for continuous spinning operation. Like this,
A U-shaped can feed conveyor capable of intermittently transferring a predetermined number of cans is disposed upstream of the sliver supply unit of the post-process machine so that the U-shaped portion is located below the sliver supply unit. A transportable can conveyor is installed so as to pass through the downstream position of each pre-process machine, and each pre-process machine is equipped with a can exchange device that can exchange a full can and an empty can on the can transport conveyor. The upstream side of the conveyor is connected to the exit of the cans feed conveyor, and the downstream side of the cans conveyor is connected to the entrance of the cans feed conveyor, and the full can can be rotated around the axis of the cans feed conveyor near the entrance.

Action When the can is filled by the sliver in each pre-process machine, the can changing device is activated to move the can to the can transport conveyor, receive the empty can on the can transport conveyor, and store the sliver in the empty can again. . The full can that has been moved onto the can conveyer is conveyed to the can feed conveyor on the upstream side of the post-process machine. In the can feed conveyor, the full can is first moved to the rotating position of the can rotating device, and the suction nozzle is moved to a position near the upper part of the full can at the rotating position. In this state, the full can is rotated by the can rotating device, and as a result, the sliver end located above the full can is gripped by the sliver take-out device. The sliver take-out device moves the sliver end portion upward and transfers the sliver end portion to the sliver gripping and supplying device. The sliver gripping and feeding device grips the sliver end and supplies it to the sliver feeding unit of the post-machine. Further, the full can is moved by one can when the preceding can becomes an empty can or becomes close to the empty can, whereby the preceding empty can is sent to the can conveying conveyor. The empty cans sent out on the can transporting conveyor are sent to the can changing device of each preceding process machine.

It is configured to extrude onto one. The can transporting conveyor 4 may be composed of a single roller conveyor capable of rotating in the forward and reverse directions, and control can be performed such that the empty cans are discharged to the roller conveyor alternately.

In the above-mentioned structure, when the can 11 at the sliver housing position 8 becomes full can 11b in each carding machine 1, the air cylinder 15 is activated after it is confirmed by the photocell 19 that there is an empty can 11a at the standby position 10. Temankens 11b
Is extruded to the extrusion position 12, and the empty can 11a is supplied to the sliver accommodation position 8. By this can changing operation, the transition sliver between the coiler wheel 7 and the full can 11b is clamped between the sliver saucer of the empty can 11a and the coiler plate 5, and between the full can 11b and the sliver holding plate 26, respectively, and then the empty by the rotary table 9. Kens 11a
Is cut on the empty can 11a side, and as a result, the sliver end of the full can 11b hangs to the upper side of the full can 11b. Next, the discharge position on the can conveyance conveyor 4
After it is confirmed by the light receiving device 23b that there is no can 11 in 24, the air cylinder 17 is activated to push the full can 11b at the pushing position 12 to the discharging position 24. The extruded full can 11b is conveyed in the direction of the arrow in FIG. 1 by the roller conveyor 61, the can transfer device 63, and the roller conveyor 62. When the photo detector 69b detects that the full can 11b has been transferred to the return position 68, when the photo tube 71 detects that the full can 11b is present at the receiving position 38, the roller conveyor
The rotation of 62 is temporarily stopped, and during the stop, the air cylinder 66 operates to return the full can 11b at the returning position 68 to the roller conveyor 61 through the bypass passage 64. In addition,
Generally, by balancing the total production capacity of each carding machine 1 and the production capacity of the drawing machine 2, the above-mentioned full cans 11b
It is possible to eliminate or reduce the returning operation of. Further, a pool place for the full cans 11b may be provided between the return position 68 and the receiving position 38 so that the full cans 11b do not perform the returning operation. When the full can 11b is moved to the return position 68, it is confirmed that there is no full can 11b at the receiving position 38 by the photoelectric tube 71.
, The rotation of the roller conveyor 62 is continued, and the full can 11b is transferred to the receiving device 38.

Next, when it is detected that the sliver of the head of the feed can 11c row located on the roller conveyor 33 of the drawing machine 2 is exhausted or the remaining sliver is reduced by a detector such as a photoelectric tube (not shown), the can is detected. The transfer arm 36 and the roller conveyor 33 rotate simultaneously to turn the turntable 41.
The upper full can 11b is moved onto the roller conveyor 33, and the full can 11b at the receiving position 38 is turned on the turntable 4
Empty can 1 on roller conveyor 33
1a is sent out onto the roller conveyor 61 of the can transporting conveyor 4, and each feed can 11c is integrally moved in an arc shape by one can. Cans transfer arm as above
When 36 turns 90 degrees and stops, and when the full can 11b is moved onto the turntable 41, the turning device 43 is activated by the completion command of the operation, and is standing by at the retracted position shown by the solid line in FIG. The suction arm 45 rotates counterclockwise in FIG. 3 to reach the forward position shown by the phantom line in FIG. 3, and then the suction arm 45 moves from the raised position via the swinging device 44 to the forward position in FIG. , The suction nozzle 46 of the suction arm 45 approaches the upper side of the full can 11b at the outlet position, and then suction of the suction nozzle 46 is started. When the suction arm 45 reaches the lowered position and a limit switch (not shown) is actuated, the turntable 41 is rotated by the detection command to rotate the full can 11b in the arrow direction (clockwise direction in FIG. 3). As a result, the end of the sliver hanging from the full can 11b is adsorbed to the wire mesh surface of the suction nozzle 46. When a detector such as a photoelectric tube attached to the suction nozzle 46 detects the sliver captured by the suction nozzle 46, rotation of the turntable 41 is stopped, and the swinging device 44 is actuated by the detection signal to cause the suction arm 45. Goes up from the lowered position and pulls out the sliver from the full can 11b. When the suction arm 45 reaches the raised position, the swivel device
43 is actuated, the suction arm 45 pivots clockwise in FIG. 3 and returns to the retracted position shown by the solid line in FIG. As a result, the sliver pulled up from Mankens 11b is the 4th
As shown in the figure, the gripping roller 53 on the fixed side of the sliver gripping and feeding device 47 is held in the open state at the gripping position.
And the movable side gripping roller 56. Next, when the detecting device 58 such as a photoelectric tube detects the sliver introduced between the gripping rollers 53 and 56, the movable gripping roller 56 is moved to the fourth position via a swinging motor (not shown) by the detection signal. The sliver pulled up is gripped by the gripping roller 56 on the movable side and the gripping roller 53 on the fixed side by rotating clockwise in the figure. Also, the sliver is a gripping roller.
When gripped by 53 and 56, the suction nozzle 46 and suction source of the suction arm 45 that have adsorbed the ends of the sliver are stopped, and the tip end of the lifted sliver is below the V guide 59 and the receiving plate (shown in the figure). (Omitted) Drop up. When the tip of the sliver is released in this way, the motor M1
Is activated, and the gripping roller 53 on the fixed side and the gripping roller 56 on the movable side reversely rotate via the friction rollers 55 and 54 to pull back the gripped sliver to the full can 11b side, and the tip of the sliver is moved by a photoelectric tube or the like. When the detection device 58 detects, the reverse feeding motor M1 stops and the gripping rollers 53 and 56 also stop. By pulling back this sliver,
The length of protrusion of the sliver end to the reverse side of 56 is extremely short. In this way, the sliver gripping and feeding device 47 gripping and pulling back the sliver pulled up from the full can 11b has its swing arm 52 and gripping rollers 53, 56, and the next cans transfer arm 36 and roller conveyor 33. It waits in the gripping position until it is rotated. Thereafter, the can transfer arm 36 and the roller conveyor 33 are rotated, and the feed can 11 is rotated.
When one of the c is emptied and the sliver end of the feed can 11c approaches the feed rollers 48a, 48b, and a command is issued from a succeeding command means such as a photoelectric tube (not shown), a command is issued based on the command. The rocking motor 51 is actuated, and the rocking arm 52 and the gripping rollers 53 and 56 waiting at the gripping position move to the front supply position. In this case, since the sliver ends of the gripping rollers 53 and 56 projecting toward the delivery side are short in length, the sliver ends do not bend during the movement of the gripping rollers 53 and 56, and the gripping rollers 53 and 56 are at the supply position. The friction roller 54 fixed to the shaft end of the gripping roller 53,
The gripping roller is pressed against the rotating feeding friction roller 60.
53 and 56 respectively rotate in the forward direction, the grasped sliver is fed forward, and the tip end of the sliver is fed to the feed roller 48.
It is sent between a and 48b. In this way, when a new sliver is gripped between the feed rollers 48a and 48b of the drawing machine 2, the screw guide 49 arranged upstream of the feed roller 48a rotates once by the rotation of the motor M2, and the spinning is performed. Move the other sliver that is out sideways by one pitch. When a new sliver as described above is supplied to the kneading machine 2, in general, the sliver start end and the sliver end do not exactly match in phase, and thus the thickness of the spun sliver varies. However, this thickness fluctuation of the sliver is removed by the auto-leveler, so that a uniform sliver can be spun out. When a new sliver is gripped between the feed rollers 48a and 48b, the movable gripping roller 56 and its swing rod 57 are opened through a swing motor (not shown), and the grip rollers 53 and 56 are opened. The sliver that has come out of the inside enters into the groove on one side of the screw guide 49 that is vacated by the lateral movement, and is continuously supplied. When a new sliver comes out of the gripping rollers 53 and 56, the gripping rollers 53 and 56 and the swing arm 52 return from the supply position to the gripping position via the swing motor 51, and the gripping rollers 53 and 56 stop. , The movable-side gripping roller 56 is opened and waits until the next sliver supply. Thereafter, each time the full can 11b is transferred onto the turntable 41 at the exit position by the rotation of the can transfer arm 36 on the side of the kneading machine 2, the suction arm 45, the sliver gripping and supplying device 47, etc. are respectively described above. A new sliver is operated in the same manner as the above, but feed rollers 48a and 48b of the drawing machine 2 are operated.
Automatically supply to

Next, the empty cans 11a and the full cans 11b extruded onto the roller conveyor 61 of the can conveyor 4 are moved rearward on the roller conveyor 61. And these cans
When the light receiver 22b detects that 11 has been moved to the supply position 21 corresponding to each carding machine 1, if the photoelectric tube 19 detects that there is no empty can 11a at the standby position 10 at that time,
After confirming that the can 11 is the empty can 11a by the photoelectric tube 20, the roller conveyor 61 is temporarily stopped, the air cylinder 13 is operated, and the empty can 11a at the supply position 21 is taken into the standby position 10. In this case, standby position 1
When there is an empty can 11a at 0 or when that can 11 is full 11
When it is a, the rotation of the roller conveyor 61 is continued,
It is circulated and moved on the can transporting conveyor 4. In addition, the empty cans circulated by the can conveyer 4 by balancing the capabilities of the carding machine group 1 and the drawing machine 2.
11b can be eliminated or reduced.

Incidentally, the sliver gripping and supplying device 47 in the above embodiment,
The case where the gripping means of the sliver is constituted by the pair of gripping rollers 53 and 56 has been described, but the present invention is not limited to this, and as shown in FIG. 7, the gripping rollers 53A and 56A with an apron are provided. (Or a known tenserver type gripping roller with an apron), and when the sliver is pulled back, the sliver end is pulled into the inside of the gripping rollers 53A, 56A with the apron. Since the sliver does not project to the delivery side of and 56A, the bending of the sliver tip can be completely eliminated. Further, in the sliver gripping and feeding device 47 of the above-described embodiment, the gripping roller 53 and the driving means for the backward feeding of the 56 are constituted by the motor M1 and the friction roller 55, and the driving means for the feeding is constituted by the gripping roller 53. Although it is constituted by the friction roller 54 fixed to the shaft end and the friction roller 60 arranged on the side of the kneading machine 2 etc., the present invention is not limited to this, and can be arranged on the swinging arm and can be rotated in the forward and reverse directions. The gripping roller may be rotated in the forward and reverse directions via the motor and the transmission means such as a pulley and a belt. Further, although the gripping rollers are attached to the driving arm, these gripping rollers may be provided on a moving body that linearly moves toward the drawing machine 2,
It goes without saying that the configuration of each part may be arbitrarily changed in design.

Further, in the present application, the sliver cutting device is configured to cut on the upper surface of the sliver with a full sliver end, and the disk-shaped or rod-shaped suction nozzle is positioned parallel to the upper surface of the sliver with a full sliver. Alternatively, the full can may be rotated to suck the end of the sliver.

As described above, in the present invention, the sliver spun by each pre-process machine is housed in a can, and the full can is conveyed to the can feed conveyor of the post-process machine and pulled out from the full can. Since the sliver is supplied to the kneading machine, it is not necessary to match the spinning capacity of the individual pre-process machines and post-process machines, and the spinning speed of each pre-process machine is limited to the post-process machine. It is possible to set the optimum capacity of the pre-process machine without being performed, and the doubling number of the sliver in the post-process machine can be arbitrarily changed without being limited to the number of the pre-process machines. Also, during operation of the post-process machine, the sliver end in the full can is protruded and pulled out upward, and the sliver end is mechanically supplied to the post-process machine.
There is an effect that the continuous supply of the sliver to the post-process machine can be automated to save labor.
