DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring spinning machine and the like, which is disposed above a peg tray transport device for transferring a peg tray on which a bobbin is mounted in one direction, and mounts an empty bobbin on the peg tray at an empty bobbin mounting position. The present invention relates to an empty bobbin mounting device.

[0002]

2. Description of the Related Art Such an empty bobbin mounting apparatus includes an empty bobbin storage box, a shooter, and an empty bobbin supply section, and changes the posture of the empty bobbins that have fallen one by one into the shooter so that the bottom is lower in the shooter. Then, the plurality of empty bobbins are sent to an empty bobbin supply unit which accommodates the empty bobbins in one row. The empty bobbin supply section is provided with a notch portion through which the tip of the peg of the peg tray can pass and a regulating member that engages with the top of the empty bobbin to regulate the movement thereof. When the peg tray moves to a position corresponding to the empty bobbin mounting device and stops, the peg tray is moved by the peg tray transport device into which the empty bobbin is inserted by the empty bobbin mounting device (see, for example, JP-A-8-188340).

The peg tray transport device transports each peg tray so that each peg tray is positioned at a predetermined position. The peg tray transport device reciprocates a pair of transfer rails provided with locking projections on the upper surface at intervals equal to the spindle pitch. It is movably provided, and between the transfer rails, during forward movement of the transfer rail, engages with the wall surface of the locking recess formed on the lower surface of the peg tray to restrict the movement of the peg tray, and allows the peg tray to move when returning. A locking lever is provided at a predetermined position (see JP-A-9-49129).

[0004]

The conventional empty bobbin mounting device has a problem that the empty bobbin is clogged in the chute. In order to solve such a problem, the inventor of the present invention has made intensive studies and as a result has obtained the following knowledge regarding the empty bobbin clogging described above.

In the peg tray conveying device, when the transfer rail is reciprocated at a stroke larger than the spindle pitch, the peg tray is moved in the feed direction at the time of reciprocation, and the locking projection engages with the outer peripheral surface of the peg tray during the movement. When the movement is completed, each peg tray is positioned at a predetermined position corresponding to the spindle. Because of this structure, the reciprocating movement of the transfer rail causes the tray to ride over the serrated locking projection of the transfer rail. Thereby, the peg tray is moved up and down by the height of the locking projection of the transfer rail. For this reason, a clearance that allows the peg tray to move up and down is provided in the transport path of the peg tray transport device.

On the other hand, in the empty bobbin mounting apparatus described above, when the empty bobbin is mounted, the bottom of the empty bobbin is hooked at the tip of the peg tray. Therefore, if there is a clearance in the bobbin mounting portion, the bobbin bottom cannot be hooked on the peg tray. Therefore, regardless of the vertical movement of the peg tray, the peg tray transport device is provided with a tray guide that regulates the upper surface of the peg tray in the bobbin mounting portion so that the empty bobbin can be securely inserted from the empty bobbin mounting device to the peg tray. Controlling the posture of the person.

[0007] Since the tray guide extends beyond the bobbin mounting portion, the posture of the peg tray is continuously controlled even after the empty bobbin is mounted at the bobbin mounting portion. For this reason, the empty bobbin mounted on the peg tray which is mounted on the empty bobbin and unloaded from the empty bobbin mounting device remains in the empty bobbin supply unit of the empty bobbin mounting device, and pushes the empty bobbin in the empty bobbin supply unit to thereby form the empty bobbin. The head of the subsequent empty bobbin comes out into the lower part of the shooter from the opposite side of the supply unit, impairing the movement of the empty bobbin that is further transferred in the shooter,
This causes the empty bobbin in the shooter to be clogged as described above.

[0008]

SUMMARY OF THE INVENTION According to the present invention, an object of the present invention is to provide an empty bobbin which is disposed above a peg tray transport device for transferring a peg tray on which a bobbin is mounted in one direction. In the empty bobbin mounting device for mounting an empty bobbin on the peg tray at the mounting position, a tray guide for guiding the tray upper surface of the peg tray is arranged along the peg tray transport device, and the empty bobbin mounted when the empty bobbin mounting position is exceeded. Is retracted to a retracted position where the top of the empty bobbin mounting device does not push up a subsequent bobbin in the empty bobbin mounting device.

In the present invention, a tray guide for guiding the upper surface of the peg tray is arranged along the peg tray transport device, and when the empty bobbin mounting position is exceeded, the top of the mounted empty bobbin is moved to a subsequent bobbin in the empty bobbin mounting device. The bobbin head does not protrude from the lower part of the shooter because
Even if the next bobbin falls in the chute, it is stored without being caught.

According to the present invention, the tray guide is arranged to extend to the empty bobbin mounting position, and when the bobbin mounting position is exceeded, the peg tray is guided by the tray guide. Preferably. By shortening the tray guide in this way, when the empty bobbin mounting position is exceeded, the top of the mounted empty bobbin is reliably retracted to the retracted position where the subsequent bobbin in the empty bobbin mounting device is not pushed up.

[0011] In particular, the present invention provides,
It is preferable that the tray guide is disposed below a regulating portion that regulates a position orthogonal to a conveying direction of the peg tray in the peg tray conveying device, so that the peg tray can tilt when the bobbin mounting position is exceeded. Thereby, the peg tray and the bobbin after the bobbin is mounted can be inclined. Therefore, by tilting the bobbin and the peg tray after the bobbin is mounted, the head of the bobbin does not protrude from the lower portion of the chute, and the bobbin is stored without being caught even if the next bobbin falls.

Fig. 3 (b) with a stroke larger than the spindle pitch of
To move the peg tray 15 in the spindle direction and position it at an interval equal to the spindle pitch, as described below.

On the upper surface of the transfer rail 10, locking projections 10a (see FIG. 3) are formed at intervals equal to the spindle pitch. As shown in FIG. The front end (the side where the transfer rail 10 transfers the peg tray 15 and the right side in FIG. 3B) extends upward at right angles from the upper surface of the transfer rail 10 and is inclined rearward from the upper end of the front end, and has a sawtooth triangle. It has a shape.

In FIG. 3A, the left and right transfer rails 1
0, the locking lever 16 is swingably supported by the shaft 17, and is locked when the transfer rail 10 moves forward (moves leftward in the figure) as shown in FIG. The lever 16 engages with a wall surface of a locking recess 15 b formed on the lower surface of the peg tray 15 to restrict the movement of the peg tray 15, and
At the time of the return movement of 0 (at the time of rightward movement in the figure), the locking lever 16 allows the peg tray 15 to move.

Furthermore, on both sides of the transfer rail 10, FIG.
As shown in (a), the guide covers 5a, 5b are fixed to the machine base F so as to extend along the transfer rail 10, and the lateral displacement of the peg tray 15 placed on the transfer rail 10 is suppressed to prevent the peg tray 15 from moving. The passage constitutes a path, and guides the peg tray 15 that is moved by the transfer rail 10 in the feed direction (to the right in FIG. 3B).

Therefore, the transfer rail 10 is reciprocated by a reciprocating member (not shown) with a stroke larger than the spindle pitch, and moves the peg tray 15 in the feed direction (rightward in FIG. 3B) when returning. During the movement, the locking projection 10a engages with the outer peripheral surface of the peg tray 15, and when the movement is completed, each peg tray 15 is positioned at a predetermined position.

As described above, in the peg tray transport device 4, the tray 15 climbs over the serrated locking projection 10a of the transfer rail 10 by the reciprocating movement of the transfer rail 10. As a result, the peg tray 15 moves the transfer rail 1
It is moved up and down by the height of the 0 locking projection 10a. For this reason, also in the connection path 6 connected to the peg tray transport device 4, a clearance C allowing the vertical movement of the peg tray 15 is provided between the regulating portion 6 d that regulates the position orthogonal to the transport direction of the peg tray 15 and the upper surface of the peg tray 15. Provided.

On the other hand, in the empty bobbin mounting device 21 described above, the bottom of the empty bobbin E is hooked at the tip of the peg tray 15 when the empty bobbin is mounted. Therefore, the empty bobbin mounting position P
If the clearance C exists, the bottom of the empty bobbin E cannot be hooked on the peg tray 15. Therefore, regardless of the vertical movement of the peg tray 15, the connecting path 6 is moved beyond the empty bobbin mounting position P as shown in FIG. 2 so that the empty bobbin can be securely inserted into the peg tray 15 from the empty bobbin mounting device 21. A study has been made to control the posture of the peg tray 15 by providing the tray guide 1 that extends and regulates the upper surface of the peg tray 15 by, for example, being bolted to a lower portion of the regulation portion 6d.

However, the tray guide 1 having this configuration is used.
As shown in FIG. 2, since the peg tray 15 extends beyond the empty bobbin mounting position P, the peg tray 15 is mounted with the empty bobbin E at the empty bobbin mounting position P, and even after leaving the empty bobbin mounting position P. The posture control is continued (as shown in FIG. 2, the upright state is maintained). For this reason, the upper part of the empty bobbin (indicated by E2 in FIG. 2) mounted on the peg tray 15 loaded with the empty bobbin E and unloaded from the empty bobbin mounting device remains in the empty bobbin supply section 39 of the empty bobbin mounting device. Empty bobbin supply unit 39

[0032] In this way, it is mounted on the peg tray 15,
When the empty bobbin E2 that has exited the empty bobbin mounting position P pushes the empty bobbin E stored in the empty bobbin supply section 39, the empty bobbin stored in the empty bobbin supply section 39 (E3 in FIG.
The head of the subsequent empty bobbin E3 protrudes into the lower portion of the shooter 38 from the opposite side of the shooter 38, impairing the movement of the further empty bobbin transferred in the shooter 38, and this causes Empty bobbin is clogged.

In the present invention, as shown in FIG. 1, by shortening the tray guide 1, the peg tray 15 is shortened.
Tray guide 1 for guiding the upper surface of tray 15
Along with the empty bobbin mounting position P,
The peg tray 15 is free from the tray guide 1 when the empty bobbin mounting position P is exceeded. Therefore, there is no clearance C at the empty bobbin mounting position P, and the empty bobbin can be securely inserted into the peg tray 15 from the empty bobbin mounting device regardless of the vertical movement of the peg tray 15. On the other hand, when the empty bobbin E1 is over the empty bobbin mounting position P, the peg tray 15 becomes free from the tray guide 1, and by tilting the bobbin E1 with the bobbin E1 after the bobbin is mounted, the head of the mounted empty bobbin E1 is moved to the next empty bobbin E. Is retracted to a retracted position where the shooter 3 is not pushed up, so that the head of the subsequent empty bobbin E does not come out from the lower portion of the shooter 38, and the shooter 3
8 does not cause empty bobbin clogging.

[0034]

According to the present invention, by shortening the tray guide 1, the peg tray 15 after the bobbin is mounted can be tilted together with the bobbin (E1 in FIG. 1) mounted thereon. Therefore, the peg tray 15 after the bobbin is mounted
By tilting the bobbin E1, the head of the subsequent empty bobbin E does not protrude from the lower portion of the shooter 38, and is stored in the empty bobbin storage portion 39 without being caught in the shooter 38 even if the subsequent empty bobbin E falls. You.

Therefore, according to the present invention, there is provided an empty bobbin mounting device 21 which does not cause empty bobbin clogging in the shooter 38.
