0b is restricted from moving. And
When the transfer member 12 moves, the inclined surface of the locking protrusion 12 a engages with the bottom surface of the peg tray 9 during the movement of the transfer member 12. When the transfer member 12 continues to move further from that state, the locking protrusion 12 a pushes up the peg tray 9 as the transfer member 12 moves, and passes below the peg tray 9. Then, when the return movement of the transfer member 12 is completed, each peg tray 9 is positioned at a position corresponding to the spindle 2. Thereafter, the immersion operation and the protruding operation of the air cylinder 13 are alternately performed, and the transfer member 12 is reciprocated, so that the peg trays 9 are sequentially transferred so as to correspond to the spindle 2 in the same manner as described above.

Since the abutment portion 20b moves inside the guide members 5a and 5b and abuts on the outer peripheral surface of the tray body 9a of the peg tray 9, the locking lever 20 has the guide members 5a and 5b.
It is less susceptible to fly waste than outside b.

When it is necessary to remove the locking lever 20 for maintenance and inspection of the bracket 16 with respect to the bracket 16, the bracket 23 and the guide members 5a and 5b are fixed at predetermined positions by removing the nut 23 and the bolt 21. In this state, the locking lever 20 and the torsion coil spring 26 are easily removed.

Therefore, in this embodiment, the following effects can be obtained. (1) Since the contact portion 20b of the locking lever 20 that contacts the peg tray 9 to perform positioning moves inside the guide members 5a and 5b, it is less affected by fly waste.

(2) The rotating portion of the locking lever 20 and the bracket 16 supporting the locking lever 20 are provided with the guide members 5a,
Since it is supported outside 5b, cleaning and maintenance inspection become easy.

(3) Openings 25 formed in the guide members 5a and 5b for inserting the distal ends of the locking levers 20 are formed in the side surfaces of the guide members 5a and 5b. Therefore,
Compared with the configuration in which the opening is formed above the guide members 5a and 5b, fly waste is less likely to enter the inside of the guide members 5a and 5b from the opening 25, and the positioning accuracy is improved.

(4) The locking lever 20 is the peg tray 9
Abuts on the peg tray 9 above the center of the tray body 9a in the height direction. Therefore, even when the peg tray 9 is pushed up by the locking projection 12a of the transfer member 12 when the transfer member 12 is moved in the direction opposite to the feeding direction,
There is no possibility that the engagement between the peg tray 9 and the locking lever 20 is released, and the positioning operation is reliably performed. In addition, since there is no fear of the above, the locking projection 12a is provided at a position corresponding to the position where the locking lever 20 is disposed, so that the transfer member 1 is provided.
2 ensures that the transfer action of the peg tray 9 is ensured.

(5) The locking lever 20 is formed of a plate material and bent toward the base end thereof.
a comes into contact with the stopper 16b disposed at the predetermined position, and is held at the regulation position. Accordingly, the area where the locking portion 20a contacts the stopper 16b is increased, and the force applied to the bent locking portion 20a is dispersed, so that the locking portion 2
0a is improved in durability. Further, the labor for fixing the locking portion 20a manufactured as a separate part to the locking lever 20 becomes unnecessary.

(6) A pair of peg tray positioning devices 15 are provided at the same position in the longitudinal direction of the guide members 5a and 5b, and the contact portion 20b has a contact surface along the peripheral surface. Therefore, even if the peg tray 9 is slightly displaced in the width direction, the peg tray 9 is guided toward the center of the guide members 5a and 5b when the transfer member 12 moves back, and positioning is performed with high accuracy.

(7) The locking lever 20 is moved to the peg tray 9
In contrast, since the positioning is performed by abutting the outer peripheral surface of the tray body 9a, the amount of rotation of the locking lever 20 is reduced. Therefore, wear due to rotation is reduced, and durability is improved.

(8) Since the guide members 5 a and 5 b support the peg tray 9, the power consumption for reciprocating the transfer member 12 is smaller than the configuration in which the transfer member 12 supports the peg tray 9. Become.

(9) Since the transfer member 12 is supported by the ball bearing 11, wear due to friction during reciprocation is reduced, and the durability of the support portion is improved. In addition,
Embodiments are not limited to the above, for example,
It may be embodied as follows.

The peg tray positioning devices 15 may be provided only on one side of the guide members 5a, 5b instead of being provided in pairs at predetermined positions in the longitudinal direction of the guide members 5a, 5b. When provided on one side, as shown in FIG. 6, it is better to attach the peg tray positioning device 15 to the guide member 5b far from the spinning machine stand. When the peg tray positioning device 15 is attached to the guide member 5a on the side closer to the spinning machine stand, the spinning machine stand is close to the peg tray positioning device 15, so that work such as loosening the bolts 17, 21 and nuts 23 during maintenance and inspection is required. Difficult to do. However, when the peg tray positioning device 15 is attached to the guide member 5b on the far side from the spinning frame, the work is easy to perform because the area around the peg tray positioning device 15 is large.

The contact portion 20b may be an arc surface having the same curvature as the outer peripheral surface of the tray body 9a. In this case, positioning is performed in a state where the contact portion 20b is in surface contact with the tray main body 9a, and the force applied to the contact portion 20b is dispersed, so that the abrasion becomes difficult.

In the case where the locking lever 20 rotates in a horizontal plane, the locking lever 20 may be configured to contact the peg tray 9 below the center of the tray body 9a in the height direction. Further, the configuration may be such that the large diameter portion 9d of the peg 9c abuts. In this case, in order to allow the upward movement of the peg tray 9, the large-diameter portion 9d is lengthened,
It is necessary to increase the distance between the portions of the guide members 5a and 5b that support the bottom surface of the tray body 9a and the portions that cover the upper surface.

In place of the structure in which the locking lever 20 is rotated in a horizontal plane, a structure in which the support shaft of the locking lever 20 is horizontally arranged as shown in FIG. 7 may be used. That is, the bracket 32 extending in the vertical direction is attached to the guide member 5 b by the bolt 17.
And the locking lever 20 is rotatably supported on a support shaft (not shown) fixed to the bracket 32. And
The distal end of the locking lever 20 is disposed so as to enter the inside of the guide member 5b from an opening 33 formed in the guide member 5b. The locking lever 20 is urged by the torsion coil spring 26 toward the side that comes into contact with the outer peripheral surface of the tray main body 9a, and the locking portion (not shown) comes into contact with the stopper and is held at a predetermined position. Also in this case, maintenance and inspection work and cleaning become easy. Further, when the transfer member 12 is moved in the direction opposite to the feed direction, there is no possibility that the engagement between the peg tray 9 and the locking lever 20 is released.

In the case of a configuration in which the support shaft of the locking lever 20 is horizontally disposed, the locking lever 20 is provided with the guide members 5a and 5b.
The guide members 5a,
5b. That is, the bracket 32, the opening 33 and the locking lever 20 are arranged at positions symmetrical with respect to a horizontal plane passing through the shaft of the bolt 17 in the state of FIG.

The locking lever 20 is connected to the support shaft 2 via a bearing.
1a. For example, a roller bearing is used as a bearing, the inner ring of which is fitted and fixed to the support shaft 21a, and the locking lever 20 is fitted to the outer ring of the roller bearing. In this case, the rotation of the locking lever 20 is performed more smoothly, and the spacers 22 and 24b become unnecessary.

A box-like case having a lid and supporting the locking lever 20 in place of the bracket 16 is used as a supporting member, and the shaft 21a of the locking lever 20 and the torsion coil spring 26 are covered. Configuration. In this case, it is difficult for fly wool to adhere to the portion of the support shaft 21a and the torsion coil spring 26, so that the maintenance inspection and cleaning cycle can be made longer, and the burden on the operator becomes lighter.

The torsion coil spring 26 is used as the urging means.
Alternatively, a tension spring may be used. The stopper 16b is not limited to the one formed by bending the bracket 16, and another part may be fixed by welding or fixed with a bolt.

The guide members 5a and 5b do not have a function of supporting the peg tray 9, but have only a guide function, and may be applied to a transport device having a known structure in which the transfer member 12 has a function of supporting the peg tray 9. .

The transfer member 12 is connected to the ball bearing 11
Instead of the support, a support bracket having a guide groove may be used as in the apparatus disclosed in Japanese Utility Model Laid-Open No. 4-4072.
