When the reset auxiliary relay RE is de-energized, it is in the energized state, and this reset auxiliary relay RE
When energized, it becomes de-energized, and in the seventh step, it becomes de-energized.

Next, the can exchange operation between the comber machine number and the wire machine number by the can transport vehicle 1 will be explained. Now, hypothetically,
It is assumed that the can transport vehicle 1 is performing a can exchange operation in sliver production group A, and during this time a call signal is sent from sliver production group B, and then a call signal is also sent from sliver production group A.

In this case, as is clear from FIG. 11, when the can conveyor 1 finishes the can exchange operation in group A and the relay contact R100 is energized, the call display relay is activated by the call signal from group A. Although JA is energized, the call display relay JB is not energized by the call signal from group B, so that the call control relay WA is kept in the energized state. At this time, since the position display relay MA is energized, the motor control relay ML is energized by the energization of the call control relay WA, which causes the moving motor M2 to rotate forward and move the can carrier 1 as shown in FIG. Move it to the left. This movement of the can carrier 1 is performed after the can carrier 1 moves to the origin position Qa of group A, the limit switch Nα29 is closed, the position relay NA is energized, and the call control relay WA and motor are energized. When the control relay ML is de-energized, it is stopped, and the can transport vehicle 1 is stopped at the origin position Qa of the group A. As described above, when the can carrier 1 receives a call signal from each group A, B, and C, it gives priority to the call signal of the group where the can carrier 1 is located, and If there is no call signal from the group where the can transport vehicle 1 is located and there is a call signal from another group, the group from which the call signal was sent will be automatically moved to the group origin position. Automatically moved to the origin position. When the can transport vehicle 1 moves to the origin position as described above, it is determined whether the can transport vehicle 1 should move to the left or right in FIG. and move toward the origin position of that group. That is, as is clear from FIG. 11, when a call signal is sent from group C, when the call signal is placed in groups A and B, when a call signal is sent from group B, and when group A is located, When a call signal is sent from group A, the can transport vehicle 1 moves to the left in FIG.
The can carrier 1 moves to the right when a call signal is sent from groups A and B when it is located in group B, and when a call signal is sent from group A when it is located in group B. Therefore, the can conveyor 1 is for each group A,
When a call signal is sent from B or C, they are efficiently moved to the most efficient group. Next, when the can transport vehicle 1 is moved to, for example, the origin position Qa of group A as described above, a series of can exchange operations is started. Now, in group A, a full can forecast signal is transmitted from the comber machine Kl of the comber machine number, and a full can request signal is transmitted from the full can request devices PD1 and PD3 of the strip machine D1 of the strip machine number. Explain that it was done. First, the moving motor M2 rotates at high speed and the can transport vehicle 1 moves at high speed to the right in FIG.
When the full can forecast signal No. 31 transmitted from the full can forecast device 11 is detected at the same time, the rotation of the moving motor M2 is switched to decelerated rotation, and when the stop position detection device 67 detects the display member 71, the motor is switched off. M2 is stopped, and as a result, the can transport vehicle 1 is stopped with the right storage position 22a facing the left can supply section 8b of the coiler part 2, as shown in FIG. 15 (1). )
. Thereafter, when the full can detection device 63 detects the full can signal from the full can indicating device 12, the replacement motor M3 of the can supply/discharge device 27 on the comber machine side rotates clockwise in FIG. As shown in FIG. 9, the combing machine is moved forward in one direction, and the suction cup 37 of the can holding frame 35 is pressed against the outer peripheral surface of the full can 9 of the can supply section 8b. In this state, a suction force is applied to the suction pipe 38, and the suction cup 37 attracts the outer circumferential surface of the full can 9. After that, the motor M3 rotates in the reverse direction, and the can holding frame 35 retreats, so that the suction cup 37 can absorb the full can 9. Figure 15 (
As shown in 2), the full can 9 is moved to the storage position 22a and placed on the roller 7b of the conveyor 7. In this state, the reverse rotation of the motor M3 is temporarily stopped J], and the suction of the full can 9 by the suction cup 37 is released, and then the motor M3 is further slightly reversed, and the suction cup 37 is moved away from the outer peripheral surface of the full can 9 in the storage position 22a. separated. Next, the moving motor M2 rotates at a reduced speed to move the can carrier 1 to the right, and when the stop position detection device 68 detects the display member 71 due to this movement, the motor M2 is stopped, and the can carrier 1 is moved to the 15th can carrier 1.
As shown in Figure (3), the storage position 22a on the right side is stopped in a state facing the can supply section 8a on the right side (second step)
. Furthermore, as the can transport vehicle 1 moves to the right as described above, the full cans 9 in the right storage position 22a are relatively moved to the left storage position 22b. Next, the motor M3 of the can supply/discharge device 27 on the comber machine side is operated again, and the full can 9 on the right side is stored on the right side as shown in FIG. 15 (4) in the same manner as the full can 9 on the left side. position 22a
move it to After that, the motor M4 of the can holding device 56
rotates forward and moves the holding frame 57 toward the full can 9 side as shown in FIG. As it is pressed, a suction force acts on the suction tube 60, and the full can 9 on the right side is suctioned and held by the suction cup 59. On the other hand, from the time when the can carrier 1 starts moving rightward from the origin position Qa as described above, the right storage position 22a of the can carrier 1 is moved to the right can supply section 8a of the comber machine.
The full can request detection device 65 of the can transport vehicle 1 is moved to a position opposite to the full can request devices PDI, P.
The full can request signal D3 is detected, whereby the auxiliary relay RQ of the direction determination circuit shown in FIG. 12 is held in the energized state, and the motor control relay ML is energized. Therefore, the moving motor M2 is then operated to move the can carrier 1, but in this case, as the motor control relay ML is energized as described above, the motor M2 is reversed to move the can carrier 1 to the left. move it. Further, in the above case, the moving motor M2 is connected to the can conveyor 1 from FIG. 15(2) to FIG. 15(
While moving to the position 3), the full can request detection devices 66a, 6
When 6b detects a full can request signal, it rotates at a low speed, and when it does not, it rotates at a high speed. Therefore, in the above case, the moving motor M2
rotates at high speed and moves the can carrier 1 to the left by 7 heights. When the full can request detection device 66b detects a full can request signal from the full can request device PD3 due to this movement, the motor M
2 to low speed rotation, and then when the stop position detection device 70 detects the display member 72, the rotation of the motor M2 is stopped, and the can conveyor 1 is moved to the storage position on the left side as shown in FIG. 15 (6). 22b is stopped in a state facing the main conveyor 15 (third step). Next, the motor M4 of the can holding device 56 rotates in reverse to move the holding frame 57 to the first position.
As shown in FIG. 5 (6), the full can 9 is moved to the right by a predetermined amount, whereby the full can 9 in the storage position 22a is moved to the right by the suction of the suction cup 59 and separated from the full can 9 on the left. Thereafter, the replacement motor (not shown) of the can supply/discharge device 28 for the drawing machine rotates normally to move the can holding frame 35 to the drawing machine D.
As a result, the pair of receiving members 39 come into contact with the outer peripheral surface of the full can 9 in the storage position 22b, and this No.
3.5 The full cans 9 are pushed onto the rollers 15b of the main conveyor 15 as shown in FIG. 15 (7), and then the motor is reversely rotated to return the can holding frame 35 to its original position. Next, the moving motor M2 rotates at a reduced speed to move the can carrier 1 to the left, and when the stop position detection device 69 detects the display member 72 due to this movement, the motor M2 is stopped. As shown in FIG. 15(8), the right storage position 22a is stopped in a state facing the main conveyor 15. Next, the suction and holding of the full can 9 by the suction cup 59 of the can holding device 56 is released, and the holding frame 5
7 is returned to its original position, and then the motor M2 rotates at a reduced speed to move the can transport vehicle 1 to the right. When the stop position detection device 70 detects the display member 72 due to this movement, the motor M2 is stopped, and the can transport vehicle 1 is moved to the right. The full can 9 is moved from the storage position 22a to the left storage position 22b, and the can transport vehicle 1 moves the full can 9 as shown in FIG. 15(9).
is stopped facing the main conveyor 15 (
4th step). After that, the can supply/discharge device 28 operates in the same manner as described above to move the full can 9 in the storage position [22b] to the storage position [22b].
As shown in 0), the full cans 9 fed earlier are pushed onto the main conveyor 15 and moved. Next, the moving motor M2 rotates at high speed to move the can carrier 1 to the right, and as a result of this movement, a dog (not shown) operates a switch to the deceleration limit 1, switching the motor M2 to deceleration rotation, and then When the stop position detection device 70 detects the display member 72, the motor M2 is stopped, and the can conveyor 1 is moved to the left storage position 22b at the rear end of the sub-conveyor 16, as shown in FIG. 15 (11). It is stopped in a state facing the second to last empty can 9 above (fifth step). Next, the motor of the can supply/discharge device 28 rotates forward to move the can holding frame 35 forward, and the suction cup 37 is moved to the empty can 9.
The can holding frame 35 is moved backward by the motor in reverse order, and the empty cans 9 are transferred to the sub-conveyor as shown in FIG. 15 (12).
16 into the storage position 22b and move it onto the conveyor 7. Thereafter, the motor M2 for the movement Nα37 rotates at a reduced speed to move the can transport vehicle 1 to the left, and when the stop position detection device 69 detects the display member 72 due to this movement, the motor M2 is stopped, and the can storage section 22 The empty can 9 inside is relatively moved to the storage position 22a on the right side, and the can transport vehicle 1 is moved to the 15th storage position 22a.
As shown in FIG. 13, the storage position 22b on the left side is stopped in a state facing the rearmost empty can 9 on the sub-conveyor 16 (sixth step). Next, the can supply/discharge device 28 operates again to move the empty cans 9 on the sub-conveyor 16 as shown in FIG.
14), move it to the storage position 22b. Thereafter, the can holding device 56 operates to hold the two empty cans 9.9 against the left leg of the vehicle body 19 as shown in FIG. 15 (15), and the rear movement motor M2 is activated. The can carrier 1 is moved toward the original comber 1, and in this case, the moving direction of the moving motor M2 is controlled by a return device 84 shown in FIGS. 13 and 14.

That is, in the third step, the can conveyor 1 is moved as shown in FIG.
When the combing machine shown in 5) is moved from the 1st position to the 15th wire machine D1 position shown in FIG. Since RVb is open and the switching relay KH is excited and its relay contact RHb is open, the counter 89 adds up the pulse signal as the pulse transmitting plate 87 rotates. Also, in the fifth step, the can conveyor 1 moves from the position shown in FIG. 15 (1o) to the
When approaching the position shown in Figure (11), auxiliary relay RQ is energized as described above, and auxiliary relay RE is not energized on the way to reset 1, and switching relay Rl-1 is not activated. Since it is kept in an excited state, the counter 89 subtracts the pulse signal as the pulse transmitting plate 87 rotates. In the above case, auxiliary relays R and Q may be in a de-energized state depending on the location where the full can forecast signal or the full can request signal is sent, but in this case, the switching relay R
H becomes excited, the counter 89 adds up the pulse signal, and stores the fact that the can carrier 1 moves away from its original position due to the movement of the can carrier 1 in the fifth step. Furthermore, when the auxiliary relay RQ is energized, the stop position detection device 68 may detect the display member of the original comber machine during the movement of the can carrier 1 and pass through the original position. After passing the original position, the beam cell 1 - auxiliary relay RE is energized, so after passing the original position, the switching relay RH becomes energized, and the counter 89 changes from subtraction to addition, and returns to the original position. It is memorized that the can carrier 1 moves away from its original position after passing.

Also, in the sixth step, the can conveyor 1 is moved as shown in Fig. 15 (
When moving from the position shown in 12) to the position shown in FIG. 15 (13), in this embodiment, the auxiliary relay RQ is in the energized state and the reset auxiliary relay 4E is in the de-energized state, so the switching relay RH is excited, and the counter 89 adds up the pulse signal to memorize that the can carrier 1 is moving away from its original position. In the above case, depending on the location where the full can forecast signal or the full can request signal is sent, the auxiliary relay RQ may be in a de-energized state, but in this case, the switching relay R
When H becomes de-energized, the counter 89 subtracts the pulse signal and memorizes that the can carrier 1 approaches the original position. Furthermore, when the auxiliary relay RQ is in the energized or de-energized state, the can carrier 1 may pass the original position due to movement in the sixth stroke, and in this case, the switching relay R
It is stored that H becomes de-energized and the can transport vehicle 1 moves away from its original position. As mentioned above, by moving the can carrier 1 in step 3.5.6, the can carrier 1 is
The counter 89 adds a pulse signal when the distance moves away from the original position, and subtracts the pulse signal when the distance moves away from the original position. Therefore, according to the count value of the counter 89, the can transport vehicle 1
The distance between the can carrier 1 and the original comber machine can be determined, and the distance between the can carrier 1 and the original comber machine when the can carrier 1 moves from FIG. The movement is performed in the direction in which the count value of the counter 89 decreases. When the full can forecast detection device 62 detects a full can forecast signal of 1 in the comber machine due to the above movement, the moving motor M2 is switched to deceleration rotation, and then the stop position detection device 68
When the display member 71 is detected Nα41, the motor M2 is stopped and the can conveyor 1 is moved to the first position.
As shown in FIG. 5 (16), the storage position 22a on the right side is stopped in a state facing the can supply section 8a on the right side. Thereafter, after the can holding device 56 releases the holding of the empty can 9, the can supply/discharge device 27 operates to move the empty can 9 as shown in FIG.
As shown in FIG. 17), the cans are pushed out to the can supply section 8a, and then the can conveyor moves one pitch to the left, and the cans are pushed out to the can supply section 8a as shown in FIG.
As shown in 18), the storage position 22a on the right side is stopped in a state facing the can supply section 8b on the left side.

Thereafter, the can supply/discharge device 27 is operated again to push out the empty can 9 to the can supply section 8b as shown in FIG. 15 (19). As described above, the can exchange operation is completed, and the reset instruction device 64 issues a reset signal. As a result, the reset detection device @13 of the comber machine 1 detects the reset signal and resets the transmission of the full can forecast signal and the full can signal, and the comber machine 1 starts spinning the sliver. . Also, when the can transporter 1 is receiving a full can forecast signal from another comber machine in the same group A, the can conveyor 1 will again enter No, /
12 Move toward the origin position Qa and start the can exchange operation, and if the full can forecast signal is not sent, the comber machine waits at the 1 position. By repeating the above-mentioned can exchange operation, the main conveyor 15 of the above-mentioned wire drawing machine D1 is
When six full cans 9 are supplied to the top, the first full can 9 pushes open the limit switch LS3 to stop the full can requesting device PD3 from transmitting the full can request signal, and the next full can exchange operation is performed without a full can. A full can 9 is fed onto the main conveyor 15 at the can requesting device PD1 position. By repeating the above operations, the required number of full cans 9 is supplied onto the main conveyor 5.15 of the wire drawing machine DI.

In this wire drawing machine D1, even while the can exchange operation is being performed, other main conveyors 15.
A spinning operation is being carried out using the full can 9 above 15.

When the cans 9 on these main conveyors 15.15 are almost empty, the operation of the stripping machine D1 is stopped, and the operation of the stripping machine D1 is stopped until the cans 9 on these main conveyors 15.15 have been supplied.
Connect the sliver to the sliver in the upper can 9 and start the operation of the wire forming machine D1 immediately. After that, switch PB1 is pressed to rotate the rollers 16b of the sub-conveyor 16, and in this state, the empty cans 9 on the main conveyor 15.15 are pushed out onto the sub-conveyor 16, and the empty cans 9 are placed at the end of the sub-conveyor 16. Transferred to limit switch L
When S5 is closed and all the empty cans 9 on the main conveyor 15.15 are pushed out, the limit switch L is
S2 and L S4 are closed, and as a result, a full can request signal is transmitted from the full can request devices PD2 and PD4. The rotation of the rollers 16b of the sub-conveyor 16 is stopped after a predetermined time set by the timer TI. Also, due to the above-mentioned can exchange operation, the two ends of the sub-conveyor 16 are
When the empty cans 9 are taken out by the can transport vehicle 1, the sub-conveyor 16 is operated for a predetermined time set by the timer T2 as shown in FIG. By feeding the empty can 9 into the limit switch L S
When the conveyor 5 is opened, the operation of the sub-conveyor 16 is stopped.

In the present application, for example, a conveyor similar to the main conveyor 15 described above is provided at one or more locations as a spare (excess) full can storage line in the line machine number of the sliver production group in the above embodiment. When the required number of full cans is loaded on all the main conveyors 15 in the line machine number of the sliver production group, and the cans of the comber machine group become full, the can conveyor moves and carries the cans. The full cans from the comber machine are conveyed onto the conveyor of the preliminary line, and then the empty cans are placed on the empty can conveyor of the drawing machine group (the required number of extra empty cans is placed on each empty can conveyor in advance). ) and transport this empty can to the above-mentioned comber machine.
By doing this, the operating rate of the comber machine group can be increased, and full cans can be replenished manually in response to simultaneous requests for full cans from the drawing machine group. As in the case of the main conveyor 15, the conveyor of the preliminary line is provided with a preliminary full can request device, a preliminary limit switch, etc. for detecting whether the conveyor is full or not, and a limit switch LS5. Even if the limit switches L81 to LS4 are in the closed operation (there are empty cans on the empty can conveyor 16) and the limit switches L81 to LS4 are in the open operation (the required number of full cans are on the main conveyor 15), the preliminary limit switch is closed. This can be done by providing a circuit that lights up the preliminary full can request device and sends out a full can request signal when the conveyor is in operation (when there are not the required number of full cans on the conveyor). In addition, in the above embodiment, two cans 9 are taken into each can transport vehicle 1 for can transport, but one can transport vehicle
A can storage section capable of storing only cans 9 may be provided, and the cans 9 may be transported one by one. In addition, although the case where cans are exchanged using a bottomless can carrier that moves on rails is shown, it is also possible to exchange cans using a can carrier that moves with tires along a signal line. It is preferable to include a can feeding device No. 46 that can reload the can 9 on the loading table of the transport vehicle. Alternatively, a full can signal may be used as a full can takeout command signal, or the can conveyor may replace cans in order from the end group of a plurality of sliver production groups. In addition, in the second embodiment, the moving direction of the can carrier when moving from the combing machine to the striping machine is determined depending on the presence or absence of a full can request signal when moving from the origin position toward the combing machine. However, regardless of the presence or absence of such a full can request signal, the can transport vehicle 1 moves in one direction (for example, to the right), and as a result of this movement, the full can request signal is transmitted by the time it reaches the moving end of the moving path. If not detected, the can conveyor g may be moved in the opposite direction to the wire stripping machine that generates the full can request signal. Also, when the can carrier moves from the comber machine position to the drawing machine position and returns to the halo comber machine, the distance of the can carrier from the comber machine is memorized and the return is made based on that memory. However, it is not limited to this. Furthermore, when a large number of sliver machines are grouped into each sliver production group, a certain sliver machine may belong to two adjacent sliver production groups. This can be easily accomplished by providing two sets of relay contact circuits for the strip machine and connecting these two sets of relay contact circuits to the relay contact circuits of the combing machines of the two sliver production groups, respectively.

As described in ``Effects'' 2, in this invention, after the can conveyor takes in the full cans spun by the comber machine, the can conveyor takes in the full cans that are spun by the comber machine, and then the can conveyor receives the full cans that require the full cans. The empty cans produced by the stripping machine are transported to the combing machine and fed to the combing machine, and the can carrier takes in the empty cans produced by the striping machine into its car.The can carrier transports the empty cans to the combing machine. Since the cans are supplied to the comber machine, the can exchange work between the comber machine and the drawing machine can be done mechanically, resulting in significant labor savings.
The sliver quality can be improved by preventing the sliver from touching the can. In addition, since the empty cans corresponding to the combing machine that supplied the bulk cans as described above are supplied to the combing machine that took out the full cans, the combing machine
The number of cans can be kept at a predetermined number at all times, eliminating troublesome can management work, and the cans can be transported efficiently using the can transport vehicle. In the can exchange work, when both the full can removal command signal from the comber machine group and the full can request signal from the line machine number are sent, the can transport vehicle moves from one end of the movement path of the sliver production group to the other end. Move in white,
This movement detects the transmitter base for the full can removal command signal and takes in a full can from the comber, and the subsequent movement of the can conveyor detects the transmitter base for the full can request signal and the line By supplying full cans to the machine and then moving the can conveyor after taking in empty cans, the original comber machine is detected and empty cans are supplied to the comber machine. Even when there are a large number of strip machines, it is possible to manage can numbers and exchanges for each comber machine or strip machine using inexpensive equipment such as a sequencer without using expensive equipment such as a computer. It has the following two effects: practical application that can be carried out at extremely low cost.
