2. Description of the Related Art In this type of spinning machine, an empty bobbin is supplied to the front of the spinning machine in a state corresponding to the spindle pitch in order to facilitate automatic pipe changing work by a pipe changing device when changing pipes due to a full pipe. A transport device that carries out the full bobbin that has been fried is required. Further, there has been proposed and implemented a spinning winder in which a spinning machine and a winder are connected by a conveyor device and an empty bobbin and a full bobbin are directly conveyed between the spinning machine and the winder. A carrier device using a peg tray is often used to carry the empty bobbin and the full bobbin.

As shown in FIGS. 5 and 6, as a transfer device of this type, transfer devices T1 and T2 are extended on both left and right sides of a spinning machine base 31, and both transfer devices T1 and T2 are attached to a gear end GE of the spinning machine base 31. It has been proposed to connect by a guide passage 32 on the side (for example, JP-A-63-275727). A feed lever 34 actuated by a cylinder 33 is provided at a position corresponding to the first end of the guide passage 32 corresponding to the first transfer device T1. A peg tray 35 having an empty bobbin attached thereto is supplied from the out-end OE side of the spinning frame 31 to the first transfer device T1 and is reciprocally rotated by the feed lever 34 to the other transfer device T2 side via the guide passage 32. Be moved. The full bobbin mounted peg tray 35 is pushed by the empty bobbin mounted peg tray 35 and is carried out from the second transfer device T2 side.

Further, in Japanese Patent Laid-Open No. 57-161133, a portion extending along the longitudinal direction of a spinning machine stand, a portion extending in a direction orthogonal to the longitudinal direction, and an arcuate portion connecting the two are formed. An apparatus has been proposed in which a guide rail is provided around a spinning machine stand and a peg tray is arranged on the guide rail. In this device, a peg tray having a locking recess on the lower surface is slidably mounted on the guide rail in a row, and a drive device having a locking claw that engages with the locking recess of the peg tray is a guide rail. It is arranged in a portion extending along the longitudinal direction of the spinning machine base. The peg tray is moved by the amount corresponding to the pitch of the spindle by the reciprocating movement of the locking claws. The peg tray circulates on the guide rails, the full bobbin discharge device provided at one end of the spinning machine stand removes the full bobbin, and the empty bobbin supply device supplies the empty bobbin to the peg tray from which the full bobbin has been removed. It is like this.

The guide member 13 is provided with a support frame 14 via a flexible bracket 15 so as to sandwich the peg 2b of the peg tray 2.
It is fixed to. The support frame 14 is arranged between the belt 12 and the gear end GE.

As for the guide member 13, the posture of the bobbin B mounted on the peg tray 2 is determined by the outlet T1 of the first transfer device T1.
It is arranged such that the intermediate portion between a and the inlet T2a of the second transfer device T2 is tilted toward the inside of the spinning machine stand 1 so as to be substantially horizontal, and is vertically disposed near the outlet T1a and the inlet T2a. There is. That is, both the guide members 13 are arranged at the same height in the vicinity of the outlet T1a and the inlet T2a, and are arranged in a state of being vertically positioned on the side opposite to the support frame 14 with respect to the belt 12 in the middle portion, and in an arc shape between them. It is bent and arranged.

As shown in FIG. 2B, the flat belt constituting the belt 12 is composed of a sliding friction core band 12a having a low friction property and a rubber layer 12b having a high friction property, and one end of the sliding contact core band 12a. Are laminated so as to project from the rubber layer 12b.
The belt 12 has a rubber layer 1 on the peg tray 2 in the middle portion.
It is arranged so that the protruding side of the sliding contact core band 12a faces the support frame 14 so as to be movable while being in contact with 2b. Guide pieces 16 (shown only in FIG. 4) for guiding both sides of the belt 12 are arranged on the support frame 14 at predetermined intervals, and contact the sliding contact core belt 12a to move the belt 12 to its width. Leaf springs 17 that press and urge in the direction are arranged at predetermined intervals. In addition, although the pressing biasing direction by the leaf spring 17 is the width direction of the belt 12, since the moving width of the belt 12 is smaller than the width of the pulleys 10 and 11,
There is no risk that the belt 12 will come off the pulleys 10 and 11.

A space exists between the transfer rail 3 of the first transfer device T1 and the belt 12 even when the transfer rail 3 is placed in the forward movement position, and a support for supporting the peg tray 2 in the space. The plate 18 is arranged.
The first end of the guide member 13 is bent in an arc shape at a position corresponding to the support plate 18, and the peg tray 2 is moved from above the transfer rail 3 onto the belt 12 in an arcuate path. There is.

The transfer rail 3 of the second transfer device T2 is formed so as to extend from the position where the belt 12 is disposed to the gear end GE side, and the peripheral surface of the peg tray 2 can be engaged with the upper surface of the end portion on the inlet T2a side. The restricting member 19 is fixed. The regulation member 19 is formed of a square plate member having a side having the same length as the diameter of the peg tray 2. The transfer rail 3 is formed in such a length that the restricting member 19 is moved to the restricting position where the restricting member 19 engages the peg tray 2 on the belt 12 to prevent the transfer rail 3 from moving while being arranged in the forward movement position. In the state where the transfer rail 3 is arranged at the returning position, the regulating member 1
9 is disposed at a retracted position where the peg tray 2 on the belt 12 cannot be engaged. The second end of the guide member 13 is the belt 1
The peg tray 2 is formed so as to move almost straight from above the transfer rail 3 onto the transfer rail 3.

Next, the operation of the apparatus configured as described above will be described. When the spinning machine base 1 is fully stopped and the pipe replacement work by the known all-mass simultaneous pipe replacement device D is completed, the full bobbin can be carried out and the empty bobbin can be supplied. When the winder issues a full bobbin request signal, the full bobbin is unloaded from the spinning frame 1 and the empty bobbin is loaded into the spinning frame 1.

When the bobbin transfer operation is started, the motor M
Are held in a driven state. First, the air cylinder of the second transfer device T2, which is the unloading side of the peg tray, is operated, and the transfer rail 3 is reciprocated from the forward movement position (position in FIG. 1) with a stroke slightly larger than the spindle pitch. The peg tray 2 is reliably transferred by the amount of forward movement of the transfer rail 3 when the transfer rail 3 is moved forward by the action of the engaging protrusions provided on the upper surface of the transfer rail 3. During the movement of the transfer rail 3, the bottom surface of the peg tray 2 engages with the top surface of the locking projection of the positioning member 6. When the transfer rail 3 further advances in this state, the peg tray 2 moves the positioning member 6 downward against the force of the plate spring 8 and passes above it, and is transferred by the amount of forward movement of the transfer rail 3. The peg tray 2 on the belt 12 is urged toward the transfer rail 3 side of the second transfer device T2, but the reciprocating movement of the transfer rail 3 causes the regulating member 19 to move integrally therewith. The bag tray 2 is prevented from moving onto the transfer rail 3.

At the time when the transfer rail 3 is completely advanced, the locking projection of the positioning member 6 is locked by the locking recess 2 of the peg tray 2.
It is arranged such that it enters the inside of a and there is a gap between the locking recess 2a and the locking projection. When the transfer rail 3 is moved back, the locking projections that have entered the locking recesses 2a engage the locking recesses 2a to prevent the peg trays 2 from retracting, and each peg tray 2 is moved to a predetermined pipe replacement position corresponding to the spindle. Will be placed. Then, when the transfer rail 3 is arranged in the returning position,
The restriction member 19 is arranged at the retracted position on the belt 12 where it cannot be engaged with the peg tray 2, and the entrance T of the second transfer device T2.
There is a space in which one peg tray 2 can be placed at a position corresponding to 2a. Then, all the peg trays 2 on the belt 12 are transferred to the entrance T2a side by the amount of one peg tray, and a space where one peg tray 2 can be placed is created at the first end of the transport device 9.

Next, the air cylinder of the first transfer device T1 is operated, and the reciprocating motion of the transfer rail 3 causes the peg tray 2 to move.
Are sequentially transferred to the gear end GE side while being in contact with each other. The top peg tray 2 is the support plate 1
8 and is guided by the guide member 13 and fed to a position where it engages with the belt 12. Hereinafter, the transfer rail 3 of the second transfer device T2 and the transfer rail 3 of the first transfer device T1 are alternately reciprocated, and the peg tray 2 on the transfer rail 3 of the transfer device T2 is placed on the full bobbin carry-out conveyor. One by one, the peg trays 2 are supplied one by one onto the transfer rails 3 of the transfer device T1 from the empty bobbin carry-in conveyor. Further, the peg tray 2 having a full bobbin or an empty bobbin mounted thereon is sequentially transferred from the first transfer device T1 to the second transfer device T2 via the transfer device 9.

The peg tray 2 sent from the first transfer device T1 to the transfer device 9 is nipped by the belt 12 and the guide member 13 and transferred to the second transfer device T2. The peg tray 2 changes its engagement position with the belt 12 according to the arrangement state of the guide member 13 and changes its posture. The peg tray 2 is engaged with the upper surface of the belt 12 in the vicinity of the outlet T1a, and the bobbin mounted on the peg 2b is moved vertically. When separated from the outlet T1a, the posture of the peg tray 2 is tilted toward the inside of the spinning frame 1 so that the bobbin B mounted on the peg 2b is substantially horizontal in correspondence with the position of the guide member 13. Is changed to. Then, the outlet T1 of the first transfer device T1
a and the intermediate portion between the inlet T2a of the second transfer device T2,
The peg tray 2 is transferred with the bobbin B held in that state. Inlet T2a of the second transfer device T2
When the bobbin B is approached to, the attitude of the bobbin B is changed again so that the bobbin B becomes vertical, and the bobbin B is sent to the inlet T2a in a vertical state. Therefore, the bobbin B is transferred together with the peg tray 2 without interfering with the wire duct 20 even if the wire duct 20 arranged between the out end and the gear end GE does not have a complicated shape bent around the gear end GE.

(Second Embodiment) Next, a second embodiment will be described with reference to FIG. In this embodiment, between the outlet T1a of the first transfer device T1 and the inlet T2a of the second transfer device T2, a guide passage 21 that does not positively move the peg tray 2 instead of the transfer device 9 is provided. The points provided are different from the above-mentioned embodiment. The same parts as those in the above embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

The guide passage 21 has an outlet T1a and an inlet T2a.
A guide member 1 as a pair of restricting portions arranged between
3 and a support bar 22 as a support portion that extends along the guide member 13 and supports the peg tray 2 in cooperation with the guide member 13. The support bar 22 is formed to have a circular cross section, and is disposed so as to be located in a horizontal plane at a position where the upper surface of the support bar 22 is at substantially the same height as the upper surface of the transfer rail 3. The first end of the support bar 22 corresponding to the outlet T1a is formed in an arc shape. The support bar 22 is fixed to the support frame 14 via the bracket 23 similarly to the guide member 13. The support bar 22 is preferably made of a material having a small frictional resistance with the peg tray 2, and a metal bar having a surface coated with a fluororesin such as polytetrafluoroethylene is used.

In the apparatus of this embodiment, the peg tray 2 is pushed by the subsequent peg tray 2 which is sequentially fed from the outlet T1a of the first transfer device T1 and moves on the guide passage 21. Similar to the above embodiment, first, the second transfer device T2
The reciprocating movement of the transfer rail 3 causes a space in which one peg tray 2 can be placed at a position corresponding to the inlet T2a of the second transfer device T2. Next, the reciprocating movement of the transfer rail 3 of the first transfer device T1 causes the peg trays 2 to be sequentially transferred to the gear end GE side while being in contact with each other. The leading peg tray 2 on the transfer rail 3 of the first transfer device T1 is fed into the guide passage 21, and the peg tray 2 in the guide passage 21 is sequentially moved to the second transfer device T2 side. The peg tray 2 at the head of the guide passage 21 is pushed out onto the transfer rail 3 of the second transfer device T2. Hereinafter, the transfer rail 3 of the second transfer device T2
And the transfer rail 3 of the first transfer device T1 are alternately reciprocated, and the peg tray 2 having the full bobbin or the empty bobbin mounted thereon is sequentially transferred from the first transfer device T1 to the second transfer device via the guide passage 21. It is transferred to the transfer device T2.

In the peg tray 2, the attitude of the bobbin B mounted on the peg 2b is the same as in the above-described embodiment, and the posture of the bobbin B is the outlet T1a of the first transfer device T1 and the inlet T2a of the second transfer device T2.
At the intermediate portion between and, the posture is changed so as to be inclined to the inside of the spinning frame 1, and the spinning frame is transferred. In the device of this embodiment, the structure of the guide passage 21 is simpler than that of the transport device 9 of the first embodiment.

The present invention is not limited to the above embodiment, but may be embodied as follows, for example. (1) The peg tray 2 is located at the intermediate portion between the transfer devices T1 and T2.
The posture when moving is bobbin B and peg tray 2
Does not have to be substantially horizontal, as long as it does not interfere with the wire duct or the like, and the bobbin B may extend obliquely upward.

(2) Endless belt 1 in the first embodiment
2 is not limited to a flat belt having a three-layer structure, and a flat belt having a single-layer structure, a V belt, or a round belt may be used. In the case of a round belt, the posture of the peg tray 2 can be easily changed. Further, the leaf spring 17 that biases the belt 12 toward the guide member 13 may be omitted.

(3) It is necessary to move the endless belt 12 by one peg tray without keeping the motor M of the carrying device 9 in a driving state during the work of carrying out the full bobbin and carrying in the empty bobbin. It may be driven only intermittently. In this case, the regulating member 19 may not be provided on the transfer rail 3.

(4) In the first embodiment, the peg trays 2 do not necessarily need to be arranged on the transfer device 9 in a state of always abutting each other, but may be finally arranged on both the transfer devices T1 and T2. . For example, the number of peg trays 2 sent from the first transfer device T1 to the transport device 9 is provided by providing sensors for detecting the peg trays 2 with bobbins mounted on the first end and the second end of the transport device 9. To count. Then, after reaching the predetermined number, the operation of the first transfer device T1 is stopped, and thereafter, only the second transfer device T2 is operated to dispose the peg tray 2 at the predetermined position. In this case, the number of peg trays 2 can be reduced.

(5) Instead of the transfer device T1 and T2 in which the peg trays 2 are mounted in a single row and the transfer rail 3 which reciprocates is used, the device disclosed in JP-A-60-139836 is used. As described above, a device may be adopted in which the peg tray is placed on the guide rail and the rod provided with the locking claw is reciprocally moved by the air cylinder.

(6) Belt conveyors may be used as the transfer devices T1 and T2. In this case, it is difficult to arrange the peg tray 2 at a predetermined pitch corresponding to the spindle row. Therefore, instead of the pipe changing device of the whole weight simultaneous type,
Like the pipe changer disclosed in Japanese Patent Laid-Open No. 3212266, it is preferable to use a pipe changer that takes the bobbins on the transfer devices T1 and T2 together with the peg tray into the device to perform the pipe change operation.

(7) The peg tray 2 may be loaded into and unloaded from the transfer device from the gear end GE side instead of from the out end side of the spinning frame 1. In this case, the transport device 9 and the guide passage 21 are arranged inside the out end.

[0038]

As described in detail above, the first to third aspects of the invention are described.
According to the invention described in (1), it is not necessary to process a member such as a wire duct into a complicated shape, and further, it is arranged on both left and right sides of the spinning machine base without widening the space for disposing the spinning machine base and the bobbin transfer device. The peg tray can be conveyed from the first transfer device to the second transfer device inside the spinning machine stand between the pair of transfer devices. Further, in the invention described in claim 3, the structure is simplified.
