Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bobbin supporting member for supporting a bobbin, a lower transfer position for transferring the bobbin between the bobbin and a bobbin wheel of the roving frame, and a pipe supporting tool above the roving frame. The present invention relates to a changer for a roving machine equipped with an elevating device for elevating and lowering the bobbin between upper and lower delivery positions.

2. Description of the Related Art There have been many proposals for a changer for a roving spinning machine, and for example, Japanese Patent Laid-Open No. 50-89642 discloses a moving machine along the front of the roving spinning machine.
A tube changer that can be stopped is disclosed. In this pipe changer, a bracket is attached to a pair of columns standing upright from the frame so that the bracket can move up and down, an arm that can move forward toward the roving frame is attached to the bracket, and two bobbins of two bobbins are attached to the tip of the arm. A pipe support mechanism (bobbin support member) capable of simultaneously supporting and hanging the upper part, and a lower delivery position for delivering the bobbin between the bobbin support member and the bobbin rail of the roving frame; and a pipe support tool above the roving frame. The bobbin is moved up and down between the upper delivery position and the upper delivery position.

Problems to be Solved by the Invention According to the above-mentioned conventional technology, the pipe support mechanism moves back and forth with respect to the bracket supported up and down on the support column, but does not move vertically. Therefore, the amount of movement of the pipe support mechanism that raises and lowers the bobbin between the lower delivery position and the upper delivery position becomes the amount of movement of the bracket as it is. In particular, as in this conventional technique, a pipe changer that supports the upper portion of the bobbin. In the above, since the upper end of the support column is located above the pipe support above the roving frame, the height of the pipe changer becomes higher and larger, and the pipe change operation cannot be speeded up. There were many problems such as the need to increase the rigidity of the columns.

Means for Solving the Problems In order to solve the above problems, the present invention supports a block that is supported by a main body of a pipe changer so as to be vertically movable, and a bobbin support member that is vertically movable on the support block. A bobbin supporting member elevating device is composed of the elevating and lowering supporting mechanism, and the bobbin supporting member is relatively elevated with respect to the supporting block as the supporting block is elevated to be positioned at an upper delivery position above the supporting block. , With the descending support block,
It is characterized in that the bobbin supporting member is lowered relative to the supporting block so as to be positioned at the lower delivery position.

Operation According to the above configuration, when the bobbin support member is moved to the upper delivery position, the bobbin support member is further raised with respect to the support block and is positioned at the upper delivery position as the support block is raised. Further, when the bobbin supporting member is moved to the lower delivery position, the bobbin supporting member is further lowered with respect to the supporting block and is positioned at the lower delivering position in accordance with the lowering of the supporting block. Therefore, the bobbin supporting member is moved up and down. The amount can be made larger than the amount of vertical movement of the support block,
When the bobbin support member is in the upper delivery position, the position of the support block is lower than that, and the amount of vertical movement of the support block is shorter than before.

6 and 97 are arranged in a line from zigzag with the full bobbin FB hanging, and stop at the delivery position where each full bobbin FB that is taken out just above each peg 20 of the full bobbin begg bar 18 is located. The peck bar 18 for full bobbins slightly moves up and the full bobbins FB are placed on the respective pegs 20 at the receiving position S2.
(Fig. 18 (C)). Next, the pipe replacement bar 76 is retracted to the retracted end, the elevating chain 42 is driven to raise the full bobbin peg bar 18 vertically upward, and the full bobbin FB is attached to the empty pipe support 116. At this time, the full bobbin peg bar 18 is relatively raised with respect to the slide block 26 by the cam plate 34 and the link mechanism. At the same time, the empty bobbin peg bar 19 in the standby position S7, the upper collar portion BT of the empty bobbin EB, the front, rear row pipe replacement arm 96 of the pipe replacement bar 76 at the rising end and the retreat end in a single row state, The robot is lowered and moved forward to the receiving position S6 so that the height of 97 can be inserted (Fig. 18 (D)). Next, the full bobbin peg bar 18 is lowered and stopped at the intermediate stop position S3, and the front and rear row pipe replacement arms 96 and 97, which are in the ascending end and the retreat end in a single row, are moved forward and stopped at the delivery position. Then, the empty bobbin EB is inserted below the upper collar portion BT, and then the empty bobbin peg bar 19 is slightly lowered to the completion position S5 of the lower delivery position, and the front and rear row pipe replacement arms 96 and 97 are empty. Suspend the bobbins EB in a line (Fig. 18 (E)). Next, while changing the front and rear row tube replacement arms 96 and 97 from one row to the staggered arrangement, the tube replacement bar 76 is positioned at the forward end, and the tube replacement bar 76 is lowered to move the empty bobbin wheels 5a and 5b of the roving frame 1 above. Insert the empty bobbin EB (Fig. 18 (F)). Next, the pipe replacement bar 76 is retracted to the retracted end, and the front and rear row pipe replacement arms 96 and 97 are rearranged from the staggered arrangement to the single row arrangement (FIG. 18 (G)). Next, the empty bobbin peg bar 19 at the completion position S5 of the lower transfer position is raised to the standby position S7 and retracted, and the intermediate stop position S3 is reached.
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,
The cylinder 130 moves forward, the catcher 129 swings upward, disengages from the first indexing positioning pin 127, and then the relay RLSA that turns ON the limit switch LSA at the forward end of the cylinder 130 turns ON, and the circuit 202 contact RLSA-1 is ON,
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 to rotate the drive motor 124 at a low speed in the forward direction to move the carrier tool station 118 in the direction of arrow B in FIG. . 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. 201 contact RPX-1 is OFF,
Relay RTP is also OFF, circuit 204 RPX-2 is ON, timer TR is ON
Becomes 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 positioning 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 pressed firmly to the front end of the catcher 129. When timer TR times out, timer contacts TR-1 and TR-2 are turned off
Then, the relays RMP and RPX are turned off, the timer is reset, the drive motor 124 is stopped, and as a result, the transport tool station 118 moves by one pitch P4, and as shown in FIG. The pipe replacement center CL and the second pipe replacement centers CL1 and L2 of the roving machine 1 and the conveyor unit 118 coincide with each other 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 turned on and the relay RMH is turned on to connect to the controller of the circuit 209, the contacts RMH-1, RMH-2 are closed, and the contact RTHR-2 is closed at this time, so the drive motor 124 rotates at high speed in the forward direction, Full bobbin FB for one roving machine
118 is conveyed to the spinning machine creel.

In this embodiment, since the bobbin is delivered to and from the pipe support by using the peg bar to place the bobbin on the peg, even if the height of the pipe support is the same as the conventional one, the upper delivery of the peg bar is performed. The position can be made lower than the height of the pipe support by the length of the bobbin, so that the height of the pipe changer itself from the floor can be made lower than the lower end of the bobbin when the bobbin is pivotally supported by the pipe support. The machine can be used extremely stably, and as shown in FIG. 18 (A) or (H), there is a sufficient vertical gap between the lower end of the bobbin hung on the conveyor 118 and the upper end of the pipe changer AD. Therefore, as shown in FIG. 12, at the 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 in which the bobbin is just hung is generated. 118
And the pipe changer AD do not overlap in the vertical direction even if they overlap each other in a plane, so a carriage that moves along the side of the roving frame with a transport rail and a pipe changer inside the factory installed or a pipe changer. Although it has the advantage of facilitating the layout of the traveling rail 136 (Fig. 12) of the above, as described in the above-mentioned prior art, the bobbin supporting member for supporting and suspending the upper portion of the bobbin is moved up and down. By applying the present application to the device, the movement amount between the lower delivery position and the upper delivery position of the bobbin support member becomes larger than the movement amount of the support block, and the movement amount of the support block is smaller than the conventional amount by the difference in the movement amount. Yes, the height of the pipe changer is low.

Further, in the present embodiment, the description has been given with the transport tool arranged in one line at the pitch of the spinning frame creel, but the present invention is not limited to this, and the most preferable arrangement for transporting to the spinning frame creel (for example, the zigzag of the spinning frame). Arrangement as it is, or although it is zigzag, the front and back, left and right spacing between each bobbin is changed appropriately)
However, if the zigzag arrangement of the roving machine is still possible, the front and rear of the pipe replacement bar, the left and right of the pipe replacement arm for the rear row, and the front and rear interval changing device may be omitted. Further, in the present embodiment, the staggered arrangement of the roving frame is changed to the bobbin arrangement (one row) of the creel of the spinning frame only by the doffing operation of the pipe changer, so that the full bobbin that is fried is conveyed to the spinning frame. Post-processing can be simplified. Furthermore,
In the present embodiment, since the empty bobbin peg bar lower delivery positions are the same, the control positions of the pipe replacement bar can be set to three positions (front, rear end and intermediate positions), which facilitates control of the pipe replacement bar. Moreover, the space required in the longitudinal direction 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 this embodiment, but may be those using a screw feed mechanism or cylinders as shown in, for example, JP-A-60-167940. 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, the upper and lower delivery positions of the empty bobbin peg bar are the same, but, for example, the front-rear motive mechanism is omitted from the empty bobbin peg bar elevating device to make a vertical elevating device similar to the full bobbin peck bar, and the transport rail It may be arranged in two rows, and the full bobbin peg bar and the empty bobbin peg bar may be provided above the full bobbin transport rail and the empty bobbin transport rail, respectively. In this case, take out the full bobbin to the full bobbin peg bar, mount it on the pipe support of the vertical full bobbin transfer rail, then raise the empty bobbin peg bar to receive the empty bobbin from the empty bobbin transfer rail and lower it. After that, the procedure can also be carried out by moving the pipe replacement arm forward and supplying it to the roving frame. Further, the full and empty bobbin peg bars are provided separately, but one peg bar may be used as long as they can be shared by both.

Effects of the Invention As described above, in the present invention, an elevating device that elevates and lowers the bobbin supporting member that supports the bobbin between the lower delivery position and the upper delivery position, and a support block that is supported by the pipe replacement machine body so as to be vertically movable by a predetermined amount, The supporting block is configured to include an elevating and lowering support mechanism that supports the bobbin supporting member so that the bobbin supporting member can be moved up and down. Since the bobbin support member is located at the upper delivery position, and the bobbin support member is relatively lowered with respect to the support block as the support block descends so as to be located at the lower delivery position, the bobbin support member is located at the upper delivery position. Position of the support block is lower than that of the bobbin support member, so that even if the support block is located directly below the support during the upper part of the roving frame, Can be prevented from interfering with the bobbin hung from the pipe support, which can reduce the width of the pipe changer in the front-rear direction. Moreover, the amount of vertical movement of the support block can be shortened well, the height of the pipe changer as a whole can be made lower than in the past, the speed of the pipe changer can be increased, and the pipe changer can be downsized.
