Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty bobbin that is suspended on a tube support of a bobbin transport tool that travels on a transport rail, and a zigzag arrangement that is mounted on a bobbin wheel. The present invention relates to a method of simultaneously replacing a plurality of (N) bobbins with a replacement machine running along a machine base.

2. Description of the Related Art A pipe changing device for changing pipes by a pipe changing machine that runs along the frame of a roving machine is disclosed in Japanese Patent Laid-Open No. 50-89642. I am doing it with a replacement arm. Therefore, it is suspended on the tube support of the transport rail.
After grasping the top of each empty bobbin with the tube replacement arm and taking it out, after receiving the empty bobbin in the peg of the tube holding mechanism, rock the tube holding mechanism and move the empty bobbin to a position that does not interfere with the removal of the full bobbin. Evacuate. Then take out the full bobbin from the bobbin wheel with the tube replacement arm and attach it to the tube support of the transport rail, then return the tube holding mechanism to its original position, grasp the empty bobbin with the tube replacement arm,
Supplying empty bobbins on the bobbin wheel.

Problems to be Solved by the Invention According to the above-mentioned conventional technique, first, an empty bobbin suspended from a pipe support is removed and placed on a peg of a pipe holding mechanism, and then a pipe replacement arm is attached to the bobbin wheel and the pipe support. Since it has to make two round trips and only two can be exchanged at the same time, the replacement time becomes long. Then, the tops of the full bobbin and the empty bobbin are gripped by the pipe replacement arm, and the bobbin wheel and the pipe support are moved back and forth and vertically so that the overhang amount of the pipe replacement arm holding the heavy full bobbin increases. Moreover, the height of the rising end also becomes high. Therefore, the pipe changer becomes tall and unstable, and the pipe changer arm cannot be moved back and forth and up and down at high speed. Further, since the tube replacement arm transfers the front and rear full bobbins on the bobbin wheel to the tube support while keeping the front and rear spacing, the tube support of the carrier must be the same as the front and rear spacing of the bobbin wheel. As described above, if the full bobbin hung on the pipe support of the carrier remains staggered, it is difficult to automate the shino exchange in the spinning machine.

Means for Solving the Problems In order to solve the above problems, the present invention is as follows: (1) A full bobbin is hung by a pipe replacement arm of a delivery device, and full bobbins are arranged in a zigzag array from the staggered arrangement. And changing the adjacent bobbin pitch to the bobbin pitch P of the spinning creel and placing the bobbin on the row of pegs of the full bobbin peg bar that matches the bobbin pitch P of the spinning creel at the lower delivery position, (2) In parallel with the above step (1), the empty bobbin peg bar is moved upward from the stand-by position above the pipe replacement arm and out of the ascending / descending trajectory of the full bobbin peg bar to match the bobbin pitch P of the spinning reel. Place the empty bobbins suspended on the row of pipe supports on the row of pegs of the empty bobbin peg bar that correspond to the bobbin pitts P of the spinning creel, and then wait again. Returning step, (3) step of raising the full bobbin peg bar and inserting the full bobbin into the pipe support after removing the empty bobbin, and lowering the empty bobbin peg bar to the lower delivery position, (4) pipe replacement arm Forward, and suspend the empty bobbin at the lower delivery position, change the empty bobbin from the one-row arrangement to the staggered arrangement with the suspension, and then place the empty bobbin on the bobbin wheel, (5) tube Retract the replacement arm, raise the empty bobbin peg bar and lower the full bobbin peg bar, replace the replacement arm,
Steps of returning the full bobbin peg bar and the empty bobbin peg bar to their original positions, respectively. (6) After performing the pipe change according to the above (1) to (5), run the pipe changer along the machine base, and then A step of moving the pipe changer to a pipe change position corresponding to a plurality (N) of full bobbins and empty bobbins, wherein the steps (1) to (6) are repeated to change pipes. is there.

By the above means, the full bobbins suspended from the roving frame and taken out are changed from the staggered arrangement to the single row arrangement, placed on the full bobbin peg bar at the delivery position, and then ascended and spun. The empty bobbin peg bar is lifted from the standby position above the pipe replacement arm so that it does not interfere with the movement of the full bobbin peg bar in parallel with the creel pitch. Place the empty bobbin on the empty bobbin peg bar, lower it as it is, advance the tube replacement arm, and hang the upper part of the empty bobbin to change the empty bobbins from one row to a zigzag pattern, and then to the bobbin. Supply
Further, it is possible to return the empty bobbin peg bar to its original position, move the pipe changer to the next pipe change position, and repeatedly perform pipe replacement, thereby making the rising end height of the full bobbin peg bar lower than before. In addition, it is possible to form a one-row arrangement suitable for supplying staggered full bobbins to the spinning creels.

The full bobbin peg bar 18 which was present is lowered to the preparation position S1 of the lower delivery position (FIG. 18 (H)).

When one tube changing operation is completed in this way, the tube changing machine AD moves to the next tube changing position. At this time, the contact Pi (1 pitch feed signal) of the circuit 201 shown in FIG. 17 is closed and the relay RTP is turned on. Turns on. Then, the contact RTP-1 of the circuit 208 is turned off and the solenoid SOL of the solenoid valve of the cylinder 130 is switched,
When the cylinder 130 moves forward and the catcher 129 swings upward, it disengages from the first indexing positioning pin 127, and when the limit switch LSA is turned on at the forward end of the cylinder 130, the relay RLSA is turned on and the circuit 202 contact RLSA-1 is O
N, the relay RMP is turned ON, and accordingly the contacts RMP-1 and RMP-2 of the controller SPC of the circuit 209 are turned ON, the drive motor 124 is normally rotated at a low speed, and the carrier tool 118 is moved in the direction of arrow B in FIG. To move. Next, when the second indexing positioning pin 127 is confirmed by the proximity switch PX, the proximity switch contact PX of the circuit 203 is turned on and the relay RPX is turned on (at this time, the contact Pi is turned off), the circuit. Contact point RPX-1 of 201 is OF

Turns on. Then, the contact RTP-1 of the circuit 208 is turned on, the solenoid SOL is switched, the cylinder 130 is retracted, the catcher 129 is lowered, and during this time, the transport tool ream 118 moves at a low speed, and the second indexing has moved. The catcher 129 captures the device determining pin 127, and the drive motor 124 is normally rotated by the timer TR for a predetermined time so that the indexing positioning pin 127 is surely pressed against the front end of the catcher 129. Timer TR
The timer contacts TR-1 and TR-2 become OF
When F is reached, the relays RMP and RPX are turned off, the timer TR is reset, the drive motor 124 is stopped, and as a result, the conveyer station 118 moves by one pitch P4, and as shown in FIG. The second pipe replacement center CL of the AD and the second pipe replacement centers CL1 and L2 of the roving machine 1 and the conveyor 118 are started to start the second pipe replacement.
When the above operations are repeated and the tube change for one roving machine 1 is completed, the contact Hi is closed in the circuit 205 and the relay RTH is ON and the contact RTH is in order to transfer the transfer device station 118 to the spinning machine side at high speed.
-1 turns OFF, solenoid SOL switches, cylinder 130 for catcher 129 moves forward, catcher 129 rises, forward limit switch LSH turns ON, relay RLSA
Is ON, the relay RMH is ON, the contacts RMH-1, RMH-2 connected to the controller of the circuit 209 are closed, and the contact RTHR-2 is closed at this time, so that the drive motor 124 rotates at high speed. Conveyor equipment chain that holds one full bobbin FB for one spinning machine
118 is conveyed to the spinning machine creel.

As shown in FIG. 18 (A) or (H) of this operation explanatory view, a sufficient vertical gap is generated between the lower end of the bobbin hung on the conveyer station 118 and the upper end of the pipe changer AD. Therefore, as shown in FIG. 12, in a portion CP where the transport rails 110 and 111 and the traveling rail 15 of the pipe changer AD intersect in a plan view, the transport tool station 118 and the pipes just hanging the bobbin are connected. Even if the changer AD overlaps in a plane, it does not overlap in the vertical direction.Therefore, a transport rail and a changer in the factory are installed or a changer is installed and moved along the side of the roving machine. The layout of the rail 136 (Fig. 12) becomes easy. In the present embodiment, when the full and empty bobbin peg bars are respectively raised toward the upper delivery position, this upward movement is used to move further upward with respect to the slide block or the elevating block respectively ascending. The actual rising end of the slide block and the lifting block is lower than the upper delivery position of each peg bar, which allows the height of the pipe changer body to be made lower. Further, in this embodiment, since the empty bobbin peg bar has the same lower delivery position, the control movement position of the pipe replacement bar can be set to three positions (front, rear end and intermediate positions), and the control of the pipe replacement bar can be performed. And the space required for the forward and backward movement of the pipe replacement bar can be reduced.

In the present embodiment, the full bobbin peg bar is lifted from the preparation position to the receiving position at the lower delivery position to place the full bobbin on the full bobbin peg bar.
The full bobbin peg bar may be stopped at the receiving position of the lower delivery position, and the pipe replacement bar may be moved up and down to pass the full bobbin onto the full bobbin peg bar. Further, the transfer device of the series of transfer tools may be a conventionally known battery car. Further, the front and rear row delivery arms are not limited to those of the present embodiment, but may be those using a screw feed mechanism or cylinders as shown in Japanese Patent Application No. 58-250963. Further, although the lifting device for empty bobbins has been described using the chain and the chain sprocket, it may be driven by a belt. Further, in the present embodiment, the description has been made on the assumption that the pipes are replaced by four spindles, but the bobbin wheel arrangement of the roving machine may process an appropriate number of spindles at one time. Furthermore, although the upper and lower handing positions of the empty bobbin peg bar are the same, for example, the vertical moving mechanism is omitted from the elevator bobbin peg bar elevating device to make it a vertical elevating device similar to the full bobbin peg bar, and the transport rail is In two rows, the full bobbin peg bar and the empty bobbin peg bar may be provided with transport rails for the full bobbin and the empty bobbin, respectively.

Advantageous Effects of Invention The present invention performs the removal of a full bobbin from a bobbin wheel and the supply of an empty bobbin to the bobbin wheel with a single delivery device, and the mounting and removal of the empty bobbin to the pipe support of the transport rail is performed. Since the full and empty bobbin peg bars are mounted on the pegs in parallel, the height of the rising end of the full and empty bobbin peg bar can be reduced by the length of the bobbin. For this reason, the height of the pipe changer can be reduced and the size of the pipe changer can be reduced to ensure stable running. Therefore, the forward / backward movement and full movement of the pipe changer arm and the vertical movement of the empty peg bar can be accelerated to speed up the pipe changer speed. Further, in this method, since the removal of the empty bobbin from the transport rail and the removal of the full bobbin from the roving machine are performed at the same time in parallel, this greatly contributes to the shortening of the pipe replacement time. Moreover, in this method, the zigzag full bobbin taken out from the roving machine is used as the bobbin array of one example of the spinning creels during the tube changing operation, and this is suspended on the tube support of one example of the bobbin carrier. The roving bobbin hung on the pipe support may be transported to the spinning creel as it is, and there is also an advantage that the arrangement is not required to be changed after being hung on the transport device.
