Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cloth roll hanging/unloading mechanism in a loom for automatically loading and unloading a cloth roll onto a loom bearing, and which facilitates automatic roll replacement. and make it possible to do so reliably.

[Prior art and technical issues to be solved] Recently, Il.
! In the weaving industry, the shortage of labor has become noticeable and is a cause of restricting productivity, but on the other hand, equipment costs are also rising, creating a situation where high availability of equipment is desperately needed. . For this reason, efforts are being made to automate all kinds of work and increase equipment utilization rates with less labor.
Although the system is currently showing success, there are some automated tasks that require further improvement, and one such task is replacing cloth rolls.

At present, the problem with automatic fabric roll replacement operations is the length of time required. This is because the loom must be stopped until the roll replacement work is completed, which reduces the loom operating rate. Unfortunately, one of the reasons for the delay in the automatic replacement of cloth-wrapped rolls is that it takes a long time to open the roll support structure of the bearing, or to close the roll support structure and load and unload the roll into the bearing. I can say it.

The present invention was made in view of the above-mentioned drawbacks in the conventional automation of fabric roll changing work, and it is an object of the present invention to provide a roll simultaneous reading mechanism that can speed up the automatic fabric roll changing process. This is an issue to be addressed.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above problem are as follows.

That is, a cloth-wound roll l having key grooves 1a-la at both ends of the winding core.
In this mechanism, a bearing 11 for bearing the cloth-wrapped roll is disposed at the end of the loom drive shaft 1O so as to be able to move forward and backward in the direction of the rotation axis, and rotated together with this drive shaft 10 to rotate the cloth-wound roll. The keyway 1ala is biased toward the roll 1 direction.
A key member 22 that engages with the bearing 11 is attached to the tip of the bearing 11 so that it can move forward and backward, and the worm 24 is in a rotationally restricted state with respect to the gear box frame, and furthermore, it can be rotated relative to the bearing 11 and can move forward and backward. By attaching the worm 24 to the disabled state, the worm 24 is moved forward and backward along the bearing 11, and the gear 26 meshing with the ohm 24 is rotatably supported on the gear box frame, thereby causing the worm 24 to move forward and backward. By employing means for driving the gear 26 in forward and reverse rotations in the motor M, a mechanism for simultaneously reading the cloth-wrapped rolls in a loom, which speeds up automatic cloth-wrapped roll replacement, is provided.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on Examples.

First, as shown in FIG. 2, key grooves 1a are bored in the end surface of the fabric roll 1. On the other hand, the mechanism of this embodiment has the first
4, a bearing 11 is fitted to the drive shaft 10 by a spline so that it can slide only in the axial direction of the drive shaft 10, and a cork 21 is fixed at the tip of the bearing 11. A compression spring 23 is provided on the outer periphery of 21 so as to be slidable in the front-rear direction, and a key member 22 that matches the key groove 1a on the end face of the cloth-wrapped roll l is slidable in the front-rear direction, and this key member 22 is always biased toward the end face of the cloth-wound roll (■). is provided on the bearing 11. Note that a stopper is partially provided on the bearing 11 so that the key member 22 stops at a predetermined position. Also,
A bearing ball is inserted into the outer diameter portion of the bearing 11 in such a manner that its movement in the axial direction is restricted, and an ohm 24 is fixedly inserted therein. This warm 2
A worm screw is formed on the outer periphery of 4. This worm screw is attached to the drive gear 25 attached to the main shaft of the motor M.
An annular gear 26 meshing with the outer periphery (see Fig. 3)
The main shaft of the motor M to which the drive gear 25 is mounted and the annular gear 26 are meshed with a screw 26b on the inner peripheral side of the gear box frame 27 that surrounds all the gears.
It is rotatably supported inside via a bearing pole.

Note that the worm 24 is unable to rotate because anti-rotation pins 29 attached to the gearbox frame 27 are inserted into a plurality of holes 28 provided in the axial direction of the worm 24, respectively. Therefore, when the motor M rotates in the forward direction, the cork 2 fixed to the tip of the bearing 11 together with the worm 24
1 moves forward and enters the end hole ib of the fabric roll l,
The key member 22 located on the outer periphery is initially
When the drive shaft 10 of the loom rotates, the key member 22 is biased toward the end surface of the cloth roll l by the compression spring 23, so it fits into the key groove 1a, and the cloth roll While the roll l and the bearing 11 are connected, when the motor M is reversed, the bearing 11 is connected together with the worm 24.
, the cork 21 and the key member 22 are moved back, and the connection with the fabric roll l is released.

The function of the mechanism of this embodiment will be explained below by explaining automatic roll exchange in a loom employing the mechanism of this embodiment.

The automatic doffing mechanism used for roll exchange includes roll exchange arms 6 as roll moving means, and operates as shown in FIGS. 5 to 11. That is, when the cloth roll 1 has wound up a predetermined amount of cloth W (see Fig. 5), it is placed in front of the loom facing the trolley 2, and the roll changing arms 6 of this trolley 2 move the cloth roll 1 to the loom. The empty roll 8 loaded on the cart 2 is then transferred to the loom T and mounted on the loom T (see FIGS. 9 to 11). (see figure). In addition, 3 is a press roll that guides the woven cloth, 4 is a cloth wrapping press roll, and 5 is a rotation stopper (7, 7) is a roll mounting that supports the cloth wrapping 1 transferred onto the trolley 2 while rotating. A mounting part 9 is a roll rest that supports the cloth-wrapped roll when the cloth-wrapped roll is attached or detached;
A is a guide roll, and B is a clothing roll.

In addition, the auto dotting mechanism uses, for example, a photoelectric detector D1 as an entry detection means for detecting the entry of the roll exchange arms 6, 6 into the vicinity of the roll rest 9, and a bearing 11.
Proximity or pressure switches D2 and D3 are arranged as attachment/detachment means for detecting the most advanced position and the most retracted position of the actuator. Therefore, a roll exchange arm approach signal S is sent from the photoelectric detector D1.

If the driving motor M of the mechanism of this embodiment is reversed through the control device (Cont) according to the AND condition of the mounting signal S2 from the switch D2 indicating the cloth-wrapped roll mounting state, which is the bearing's most advanced position. , bearing 1 of cloth-wound roll 1
1 is released, and the fabric roll 1 is placed on the roll rest 9.
It will be waiting to be transferred to the top. That is, as shown in FIG. 1, the bearing 11 is in the most retracted position, and the switch D3 is in a state in which a signal S indicating the cloth-wrapped roll attachment/detachment state is generated. At this time, the roll exchange arm 6 on the trolley side has already been
6 is in a position where it can grasp the cloth roll 1 that has been detached from the loom, and then the roll changing arms 6 actuate to grip the cloth roll l and transfer it onto the trolley, and then the roll changing arms 6・6 grabs the empty roll 8 on the cart and enters onto the roll rest 9 on the loom side. Then, in that state, the bearing 11 is in the most retracted position, and the switch D2 is emitting a signal S indicating the cloth-wound roll attachment/detachment state. When this happens, the photoelectric detector D1 issues an approach signal S1, so if the drive motor M is rotated in the forward direction via the control device (Cont) according to the AND condition of these Sl and S, the cork 21 of the bearing 11 and the key The member 22 moves forward and connects with the empty roll waiting on the rest 9, and the mounting of the empty roll 8 is completed.

[Effects of the present invention]

As explained above with reference to the embodiments, the cloth-wrapped roll simultaneous reading mechanism of the present invention does not rotate the worm which is interlocked with the bearing provided on the loom drive shaft, but simply advances and retreats the roll in the axial direction using a gear driven by a motor. The bearing structure can be opened and closed to simultaneously read the fabric rolls, making the structure and process extremely simple. Therefore, it is possible to speed up the simultaneous reading of cloth-wound rolls, and it has become possible to speed up the automatic cloth-wrap-roll replacement work.

As described above, the cloth-wound roll simultaneous reading mechanism in the loom of the present invention has high industrial utility value.
