Description

Detailed Description of the Invention [Industrial Application Field] The present invention provides a heald frame transfer means capable of collectively transferring a plurality of heald frames through which warp threads of a warp beam are inserted, and a full warp beam for a loom. Attire! and a warp beam transfer means for removing the empty warp beam from the loom.The loom device is related to a slip prevention device for the warp beam transferred by the device.

[Prior Art] In order to reduce the time required for the above-mentioned work, which will improve the operating efficiency of the loom, the warp beam is attached to the loom and the warp threads are passed through the weaving equipment. For each ship, a work procedure is adopted in which the warp threads are inserted in advance through multiple heald frames.

An example of a warp beam, a warp cut detection device through which warp threads are inserted, a heald frame, and a mechanism for transporting and transferring a reed is disclosed in Japanese Patent Application Laid-Open No. 62-223344.

In this mechanism, the transfer lever of the device can engage with the warp beam shaft to support the warp beam without idling, and the warp beam is supported by the transfer lever without idling. If the warp beam idles in the warp sending direction, the warp threads are fed out and loosened, and this loosening may cause the warp threads to become entangled with each other. However, when the machine gear is supported by the transfer lever of the device, the warp beam is prevented from idling, and the warp threads are loosened. No entanglement occurs.

[Problems to be Solved by the Invention] However, as disclosed in, for example, Japanese Unexamined Patent Publication No. 63-235553, there is a method in which a warp beam is temporarily placed at a temporary warp beam placement position on a support bracket in a loom and then transferred. In this case, since the warp beam is temporarily placed in a temporary position on the support bracket via bearings at both ends of its shaft, the warp beam is very prone to idling. If the warp beam idles in the warp sending direction, the warp threads become entangled, but when such warp threads become entangled, the threads are likely to break when passing through warp passing sections such as droppers and healds of the warp cut detection device.

An object of the present invention is to provide a means that can prevent a warp beam from idling even during a temporary storage type transfer process.

[Means for Solving the Problems] In order to solve the problem, in the present invention, the mechanism is attached to the flange of the warp beam above the temporary storage position in the vicinity of the lower part of the temporary storage position of the warp beam to be transferred while being supported by the device so as not to be idling. The contacting idling prevention member is placed immovably.

[Function] For example, sponge, rubber, etc. are used as the slip prevention member, and when the warp beam is placed on the temporary position, the slip prevention member comes into pressure contact with the flange of the warp beam. As a result, idling of the warp beam is prevented by the braking action of the idling prevention member in an immovable state, and loosening of the warp threads, which may lead to entanglement of the warp threads, is eliminated.

[Example] Hereinafter, an example embodying the present invention will be described based on FIG. 1.2.

FIG. 1 shows a loom 1 and a loom device 2, and the loom device 2 has the same structure as the loom device disclosed in Japanese Patent Application Laid-Open No. 63-235553. That is, the device 2 detects the lead wire (illustrated path) laid on the floor based on the detection signal from the detection means (illustrated path).
The travel route of the vehicle is set on the lead line. This lead wire is laid so that the loom at the rear of the loom 1 passes through the working position, and the loom is connected to a predetermined loom at the rear of the loom based on a signal from a stop position detection means (not shown). Controls the stop of the transport vehicle 3 to the working position. This loom is in the working position when the auxiliary stand 4 on the transport vehicle 3 is placed on the loom 1.
Move forward toward the side and move backward away from the loom 1, and this auxiliary stand 4
In the process of back-and-forth movement, the transfer lever 5 for warp beam transfer moves up and down. Further, a straight parallel six-bar linkage mechanism 6 supported vertically movably on a column 22 on the auxiliary stand 4 moves vertically and expands and contracts back and forth. The warp beam 7, the warp cut detection device 8, and a plurality of The heald frames 9 and reeds 10 are transferred along a predetermined transfer route, and the loom work is transferred from the device 2 side to the loom I side, or from the loom 1 side to the device 2 side.

The warp beam 7 shown in FIG. 1 is attached to the loom 1, and the loom is mounted on the device 2 so that the shaft 7a of the warp beam 7 (hereinafter referred to as full warp beam) is located at the front and rear support recesses 5a on the transfer lever 5. , 5b is directly supported in the support recess 5b on the rear side. Therefore, the full warp beam 7 supported in the support recess 5b does not idle. full warp beam 7
After moving up the straight parallel six-bar link mechanism 6 that supports the warp cut detection device 8, the heald frame 9, and the reed 10 through which the warp threads T have been passed, the auxiliary stand 4 moves forward, and the shaft 7a of the full warp beam 7 It is arranged vertically above the temporary placement recess 11a on the support bracket 11 on the loom 1 side. Thereafter, the transfer lever 5 is moved down, and the bearings 7b at both ends of the shaft 7a are moved into the temporary placement recess 11a.
It will be posted on.

When the bearing 7b is placed on the temporary recess 11a,
The support recess 5b of the transfer lever 5 is spaced downward from the shaft 7a, and the full warp beam 7 is temporarily supported on the temporary recess 11a via only the bearing 7b. Therefore, if this condition continues, the full warp beam 7 may easily spin idly and the warp threads may become entangled. However, in this embodiment, an idling prevention member 12 made of sponge is fixed on the floor below the temporary storage recess 11a, and the flange 7C of the full warp beam 7 on the temporary storage recess 11a is attached to the idling prevention member 12.
be placed on top. The flange 7C is a sponge type slip prevention member 1
2, the slip prevention member 12 is elastically depressed, and this elastic deformation action causes the slip prevention member 12 to come into pressure contact with the flange 7C. This prevents the full warp beam 7 from idling on the temporary holding recess 11a, and prevents the warp yarns T from becoming entangled due to the idling of the full warp beam 7 in the warp sending-out direction.

After the full warp beam 7 is temporarily placed in the temporary placement recess 11a, the auxiliary stand 4 is once retreated, and the front support recess 5a on the transfer lever 5 comes to be directly below the temporary placement recess 11a. In this state, the transfer lever 5 moves upward, and the support recess 5a is fixed to the full warp beam 7.
The full warp beam 7 is slightly raised in contact with the axis 7a. Then, the auxiliary platform 4 moves forward again, and the full warp beam 7
is placed at the position indicated by the chain line in FIG. Then, by the downward movement of the transfer lever 5, the bearing 7b of the full warp beam 7 is
is placed on the mounting recess 11b on the support platen) 11,
The full warp beam 7 is transferred to the loom 1 side. Since the support recess 5a of the transfer lever 5 contacts and supports the shaft 7a, the full warp beam 7 will not idle during the transfer process from the temporary storage recess 11a to the mounting recess 11b.

Note that by using a sponge as the slip prevention member 12 that prevents the full warp beam 7 from slipping, the slip prevention effect is not affected by differences in the warp beam diameter or variations in the levelness of the floor surface.

After the full warp beam 7 is transferred, the warp cut detection device 8, heald frame 9, and reed 10 are transferred by advancing the auxiliary table 4 and extending and lowering the straight parallel six-bar linkage mechanism 6.

Before transferring the full warp beam 7, warp cut detection device 8, heddle frame 9, and reed 10 to the loom 1 side by the device 2, the loom was passed through the spent warp beam and its warp on the loom 1. The warp cut detection device, heald frame, and reed are transferred to the machine 2 side, but at this time as well, after the warp beam is temporarily placed on the temporary holding recess 11a, the machine work is transferred to the machine 2 side. It will be posted. Even in this temporary position, the idling prevention member 1
2 prevents the warp beam from idling.

The warp beam, warp cut detection device, heald frame, and reed are transferred to the machine 2 side, and the machine preparation receiver shown in FIG. 2 is transferred to the stand 13. This receiver is pedestal 13 in Japanese Patent Application Publication No. 63.
- The same as that disclosed in Publication No. 243352,
This receiver is used to join the warp T of the empty warp beam 14 that has been consumed on the stand 13 with the warp of a new warp beam, and to perform a warp threading operation in which the knot is drawn from the warp cut detection device 8 to the reed 10 side. . The receiver has a temporary storage recess 13 in the stand 13.
a and a mounting recess 13b are formed, and the empty warp beam 14, which has been transported by the device 2 to the transfer work position behind the platform 13, is temporarily placed as shown by the chain line in FIG. , then mounted in the solid line position. This transfer of the loom work by the device 2 is carried out in the same manner as the transfer to the loom 1 side, and the bearings 14b at both ends of the shaft 14a of the empty warp beam 14 are placed in the temporary placement recess 13a and the mounting recess 13b. A slip prevention member 15 for sponges is fixed on the floor below the temporary storage recess 13a, and the temporary storage recess 1
The flange 14c of the empty warp beam 14 on 3a contacts the slip prevention member 15.

This prevents the empty warp beam 14 above the temporary holding recess 13a from rotating idly, and prevents warp yarns from becoming entangled.

The thread splicing performed on the table 13 must be performed with the warp entangled, and if the warp threads are entangled, accurate splicing cannot be performed. Prevention of warp thread entanglement contributes to smooth thread splicing.

The present invention is, of course, not limited to the above-mentioned embodiments. For example, as shown in FIG. It is also possible to provide an idling prevention member 19 that is fitted and configured with a pressing spring 18 interposed between the support cylinder 16 and the cylinder body 17. Reference numeral 19a denotes a rubber that is fixed on the cylinder 17, and the flange 7c of the warp beam 7 above the temporary holding recess 11a comes into contact with this rubber 19a, and pushes down the cylinder 17 against the pressure spring 18. As a result, a braking action is applied to the warp beam 7, and the warp beam 7 is prevented from idling.

In FIG. 4, the mechanism is such that an idle rotation prevention member 21 made of sponge is fixed to a drive rod 20a of a hydraulic cylinder 20 attached to an appropriate part of the transport vehicle 3 of the device 2, and the idle rotation prevention member 21 is provided in a temporary storage recess. It can be switched between an operating position below 11a and a retracted position shown by a chain line. This switching arrangement may be made part of the transfer program or may be performed by push button operation. Idle rotation prevention member 21 in the working position
is the flange 7c of the warp beam 7 on the temporary placement recess 11a.
The warp beam 7 is prevented from idling. According to this embodiment, there is no need to provide an idle rotation prevention member for each loom or for each stand, which is economical.

Further, in the present invention, an embodiment in which the idling prevention member can be pulled out and placed from the loom side is also possible.

[Effects of the Invention] As described in detail above, the present invention provides that the mechanism is placed on the flange of the warp beam above the temporary storage position in the vicinity of the lower part of the temporary storage position of the warp beam to be transferred while being supported by the device so as not to be idling. Since the contacting idling prevention member is immovably arranged, the idling of the warp beam at the temporary storage position is prevented by the braking action of the idling prevention member against the flange, and it is possible to eliminate warp entanglement caused by the idling of the warp beam. be effective.
