Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a heddle frame transfer means capable of collectively transferring a plurality of heddle frames through which warp threads of a warp beam are inserted, and a full warp beam for a loom. The present invention relates to a warp beam idling prevention device that is transferred by a machine tool device including a warp beam transfer means for mounting and removing an empty warp beam from a loom.

[Prior Art] When mounting a warp beam on a loom and passing the warp threads to the weaving machine side, before installing a new warp beam, consider the time reduction of the work that leads to improvement of the operating efficiency of the loom. A work procedure in which the warp thread is inserted through a plurality of heddle frames in advance is generally adopted.

Japanese Patent Application Laid-Open No. 62-223344 discloses an example of a warp cutting detection device having a warp beam and its warp thread inserted therein, and a device for carrying and transferring a heddle frame and a reed. The transfer lever of this mechanical device can engage the warp beam shaft to support the warp beam in a non-idle manner, and the warp beam is supported by the transfer lever without idling. If the warp beam idles in the warp feed-out direction, the warp yarn will be fed out and loosen, and this looseness may cause the warp yarns to become entangled, but when the warp beam is supported by the transfer lever of the device, the warp beam is prevented from idling and warp entanglement occurs. Does not occur.

[Problems to be Solved by the Invention] However, as disclosed in, for example, Japanese Patent Application Laid-Open No. 63-235553, the warp beam is temporarily placed and transferred to the warp beam temporary placement position on the support bracket of the loom. Then, since the warp beam is temporarily placed in the temporary placement position on the support bracket via the bearings at both ends of the shaft, the warp beam is very easy to idle. If the warp beam idles in the warp delivery direction, warp entanglement occurs. However, if such warp entanglement occurs, yarn breakage easily occurs when passing through a warp cutting portion such as a dropper or a heddle.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an idling prevention device that can prevent idling of a warp beam even in the transfer process of a temporary placement system and can simplify the configuration and reduce costs.

[Means for Solving the Problem] Therefore, in the present invention, the warp beam carried by the machine setting device is temporarily placed at the temporary position of the warp beam of the loom or the machine preparation preparation cradle, and then the warp beam is regularized. In the device for moving and mounting the warp beam to the position, a slip prevention member that is in contact with the flange of the warp beam transferred onto the temporary placement position is immovably arranged near the lower position of the temporary placement position of the warp beam.

[Operation] As the idling prevention member, for example, sponge, rubber, or the like is used, and the idling prevention member presses against the flange of the warp beam when the warp beam is placed on the temporary placement position.
As a result, the idling of the warp beam is prevented by the braking action of the idling prevention member in the immobile state, and the looseness of the warp leading to the warp entanglement is eliminated.

[Embodiment] An embodiment embodying the present invention will be described below with reference to FIGS.

FIG. 1 shows a loom 1 and a machine-moving device 2. The machine-moving device 2 has the same structure as the machine-moving device disclosed in Japanese Patent Laid-Open No. 63-235553. That is, the mechanism device 2 sets the traveling route of the transport vehicle 3 on the lead wire based on the detection signal from the detection means (not shown) that detects the lead wire (not shown) laid on the floor. . This lead wire is laid so as to pass through a looming work position behind the loom 1, and the looming machine 2 is moved to a predetermined looming work position behind the loom based on a signal from a stop position detecting means (not shown). The stop of the carrier 3 is controlled. At this machine setting work position, the auxiliary base 4 on the carrier 3 moves forward toward the loom 1 and moves backward from the loom 1, and in the course of the back-and-forth movement of the auxiliary base 4, the transfer lever 5 for transferring the warp beam is moved. Move up and down. Further, the straight-moving parallel 6-joint link mechanism, which is supported by the support column 22 on the auxiliary table 4 so as to be vertically movable, vertically moves and expands and contracts back and forth. Then, such a back-and-forth movement of the auxiliary base 4 and a straight parallel 6
The warp beam 7, the warp cutting detection device 8, the plurality of heddle frames 9 and the reeds 10 are moved along a predetermined transfer path by an appropriate combination of the vertical movement of the knot link mechanism 6 and the straight translation of the 6 knot link mechanism 6. And is transferred from the weaving machine 2 side to the weaving machine 1 side or from the weaving machine 1 side to the weaving machine 2 side.

The warp beam 7 shown in FIG. 1 is mounted on the loom 1, and on the weaving device 2, the shaft 7a of the warp beam 7 (hereinafter referred to as a full warp beam) is provided on the transfer lever 5 at the front and rear supporting recesses 5a, It is directly supported by the support recess 5b on the rear side of 5b. Therefore, the idling of the full warp beam 7 supported in the support recess 5b does not occur. After the warp cutting detection device 8 through which the warp T of the full warp beam 7 is passed, the straight parallel 6-joint link mechanism 6 that supports the heddle frame 9 and the reed 10, is moved up, the auxiliary stand 4 moves forward to move the full warp beam 7 The shaft 7a is arranged vertically above the temporary placement recess 11a on the support bracket 11 on the loom 1 side. After that, the transfer lever 5 is moved downward, and the bearings 7b at both ends of the shaft 7a are placed in the temporary placement recess 11a.

When the bearing 7b is placed on the temporary placement recess 11a, the support recess 5b of the transfer lever 5 is separated downward from the shaft 7a, and the full warp beam 7 is temporarily placed via the bearing 7b only.
Temporarily placed and supported on 11a. Therefore, if it is left as it is, the full-warp beam 7 may easily idle and warp entanglement may occur. However, in this embodiment, the temporary placement recess
A slip prevention member 12 made of sponge is fixed on the floor below 11a, and the flange 7c of the full warp beam 7 on the temporary placement recess 11a is placed on the slip prevention member 12. Flange 7c
When the slip prevention member 12 made of sponge is placed on the slip prevention member 12, the slip prevention member 12 is elastically dented, and the 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 placement recess 11a, and prevents the warp yarn T from being entangled due to the idling of the full warp beam 7 in the warp feeding direction.

After the full warp beam 7 is temporarily placed in the temporary placement recess 11a, the auxiliary base 4 is once retracted, and the front support recess on the transfer lever 5 is moved.
5a comes directly below the temporary placement recess 11a. In this state, the transfer lever 5 moves upward, and the support recess 5a moves to the shaft 7a of the full warp beam 7.
The full warp beam 7 is slightly lifted by touching. Then, the auxiliary table 4 moves forward again, and the full warp beam 7 moves to the first position.
It is placed at the position indicated by the chain line in the figure. Then, the bearing 7b of the full warp beam 7 is placed on the mounting recess 11b on the support bracket 11 by the downward movement of the transfer lever 5, and 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 does not idle during the transfer process from the temporary placement recess 11a to the mounting recess 11b.

By using a sponge as the anti-slip member 12 that prevents the full-warp beam 7 from slipping, the slip-preventing action is not affected by the difference in the warp beam diameter or the variation in the levelness of the floor.

After the full-warp beam 7 is transferred, the warp cutting detection device 8, the heddle frame 9 and the reed 10 are transferred by advancing the auxiliary base 4, extending the straight parallel 6-joint link mechanism 6 and moving it downward.

Before the warp beam 7, the warp cutting detection device 8, the heddle frame 9 and the reed 10 are transferred to the loom 1 side by the machine device 2, the consumed warp beam on the loom 1 and the warp cutting through the warp threads are transferred. The detection device, the heddle frame and the reed are transferred to the mechanism device 2 side. At this time as well, the warp beam is once temporarily placed on the temporary placement recess 11a and then transferred to the mechanism device 2 side. Even in this temporary placement, the idling prevention member 12 prevents idling of the warp beam.

The warp beam, the warp cutting detection device, the heddle frame, and the reed transferred to the machine setting device 2 side are transferred to the machine preparation preparation base 13 shown in FIG. This cradle 13 is disclosed in JP-A-63-24.
This pedestal is the same as that disclosed in Japanese Patent No. 3352.
A warp operation is performed in which the warp yarn T of the empty warp beam 14 consumed on the yarn 13 is spliced with the warp yarn of the new warp beam, and the knot is pulled from the warp yarn cutting detector 8 to the reed 10 side. The cradle 13 is formed with a temporary placement recess 13a and a mounting recess 13b, and the empty warp beam 14 that has been transported to the transfer work position behind the cradle 13 by the machine tool 2 is shown by a chain line in FIG. As described above, it is temporarily placed, and then mounted in the position indicated by the solid line. This transfer by the machine setting device 2 is performed in the same manner as the transfer to the loom 1 side, and the shaft 14 of the empty warp beam 14 is
The bearings 14b at both ends of a are placed on the temporary placement recess 13a and the mounting recess 13b. A sponge slip prevention member 15 is fixed to the floor below the temporary placement recess 13a, and a flange 14c of the empty warp beam 14 on the temporary placement recess 13a contacts the slip prevention member 15. As a result, the idle warp beam 14 on the temporary placement recess 13a is prevented from idling and warp entanglement is prevented.
The yarn splicing performed on the cradle 13 needs to be performed in a state where the warp entanglement has been eliminated. If warp entanglement occurs, accurate yarn splicing cannot be performed.
The prevention of warp entanglement on the top 13 contributes to smooth yarn splicing.

Of course, the present invention is not limited to the above-described embodiment. For example, as shown in FIG. 3, the support cylinder 16 is fixed to the floor below the temporary placement recess 11a, and the support cylinder 16 is provided with the cylinder body 17. A slip prevention member 19 which is fitted and configured by interposing a pressing spring 18 between the support cylinder 16 and the cylinder 17 is also possible. 19a is a cylinder 17
The flange 7c of the warp beam 7 on the temporary placing recess 11a is in contact with the rubber 19a and pushes the cylinder 17 downward against the pressing spring 18. As a result, the warp beam 7 has a braking action, and the warp beam 7 is prevented from idling.

In FIG. 4, a sponge idling prevention member 21 is fixed to a drive rod 20a of a hydraulic cylinder 20 attached to an appropriate portion of a carrier vehicle 3 of a machine tool 2, and the idling prevention member 21 is temporarily placed in a recess 11a. It is possible to switch between the working position below and the retracted position shown by the chain line. This switching arrangement may be part of the transfer program or may be performed by push button operation. The idling prevention member 21 at the operating position contacts the flange 7c of the warp beam 7 on the temporary placement recess 11a, and the idling of the warp beam 7 is prevented. According to this embodiment, it is not necessary to dispose a slip prevention member for each loom or each receiving stand, which is economical.

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

[Effects of the Invention] As described in detail above, according to the present invention, the warp beam carried by the weaving device is temporarily placed at the warp beam temporary placement position of the loom or the weaving preparation cradle, and then the warp beam is properly moved. In the device for moving and mounting to the position of the warp beam, the idling prevention member in contact with the flange of the warp beam transferred onto the temporary placement position is immovably arranged near the temporary placement position of the warp beam. The idling of the upper warp beam is prevented by the braking action of the idling prevention member on the flange, the warp entanglement due to the idling of the warp beam can be eliminated, and the excellent effect that the cost can be reduced by the simpler configuration is exerted. .
