Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention relates to a mechanical device used to attach and remove a warp beam and a member through which warp threads are passed from the loom to a loom. .

(Prior art) In the weaving work where a warp beam is attached to a loom and the warp threads are passed through to the weaving equipment side, in order to reduce the time required for this work which will lead to improved operating efficiency of the loom, a new warp beam is installed before being installed. Generally, a work procedure is adopted in which the warp threads are inserted in advance through a plurality of warp passing members such as heald frames and reeds.

An example of a device for transporting and transferring warp beams and warp threading members through which warp threads are inserted is
It is disclosed in Publication No. 53899. In this device, the warp beam is placed and held between a pair of left and right beam receivers on the chassis, and the warp box, through which the warp threads are passed, the warp cutter detection dropper box, the heald frame, and the reed are mounted on a support mechanism that can move up and down and back and forth. The warp beam and the through member are both adapted to be manually transferred. That is, the warp beam is manually rolled and placed on the beam receiver, and the heald frame and reed are transferred by manually extending and contracting the extendable support arm. Manually operated transfer operations like this, especially when transferring heavy warp beams, pose problems in terms of worker safety and work efficiency, and it is not possible to leave such transfer operations entirely to mechanical drive. desirable.

(Problem that the invention aims to solve) In mechanical drive, positioning accuracy of transfer operation,
For example, a drive screw shaft method is cited as one of the effective drive forms from the viewpoint of locking performance, etc. However, in a drive form in which a driven transmission member that is threadedly connected to the drive screw shaft moves as the drive screw shaft rotates, The quality of the lubrication performance between the two determines the smoothness of the transfer operation, and the problem of fluff adhesion that causes such a decline in lubrication performance cannot be ignored.

Structure of the invention (means for solving problems) Therefore, the present invention includes a warp member transfer means for transferring warp thread members such as a plurality of heald frames and reeds through which warp threads of a warp beam are inserted, and a loom. A weaving device for a loom, which is equipped with a warp beam transfer means for attaching a full warp beam to a loom and removing an empty warp beam from the loom, wherein the through-hole member transfer means has a multi-jointed section capable of supporting the through-hole member. A link mechanism is provided, and the drive mechanism of the multi-articulated link mechanism includes an elongated guide body and a driven transmission member that is operatively connected to be able to drive and displace along the longitudinal direction of the guide body, is covered with a covering member, an opening is formed in the covering member to allow drive displacement of the driven transmission member, and a closing member made of a linear body is implanted in the opening. It is said that

(Function) That is, the opening of the covering member is closed by the closing member made of a linear body, and the intrusion of fluff and the like into the covering member is prevented. Then, when the driven transmission member is driven and displaced along the guide body in order to drive the passage member transfer means, the driven transmission member is displaced along the guide body while passing through the closing member made of the linear body.

A transfer operation of the weaving device which has been moved and placed to the weaving work position behind the loom 4 along the laying lead wire is performed. 1st
The weaving device shown in FIGS. 3 to 3 is in an initial state, and the empty warp beam 72 on the loom 4, the warp cut detection device 73 through which the warp threads T have been passed, the plurality of heald frames 74, and the reed 75 are detected by the transfer operation. It is transferred from the loom 4 side to the weaving device side. This transfer operation is performed with the auxiliary wheels 16 and 17 in contact with the ground, and the auxiliary platform 9
The transfer levers 67, 68 and the latching member 6 are moved by an appropriate combination of the forward and backward movement of the 6-bar link mechanism, the vertical movement of the 6-bar straight link mechanism, and the straight parallel movement of the 6-bar link mechanism.

Warp cut detection device 73, heald frame 74 and reed 75
The straight parallel movement of the straight parallel six-bar linkage mechanism for transferring is obtained from the left and right movement of the drive link 45,
The left and right movement of the drive link 45 is obtained from the rotation of the screw shaft 48 within the cover 47. The support shaft 46 that connects the drive link 45 with the ball bearing 49 that is threaded onto the screw shaft 48 moves along the slit 47a while pushing aside the linear bodies H1 and H2, and the pushed apart linear bodies H1 and H2 are supported. After passing the shaft 46, the slit 47a is closed again. Therefore, the slit 47a
This means that the cover 47 is always closed, and fly fluff floating in the weaving chamber does not enter the cover 47. This prevents fluff from adhering to the lubricated screw shaft 48, and the ball bearing 49, which affects the telescopic performance of the straight parallel six-bar link mechanism, can be smoothly engaged and moved. The drive screw shaft mechanism uses a self-deceleration function to easily determine the expansion/contraction position of the straight parallel six-bar linkage mechanism with high precision.
The self-locking action makes it easy to maintain the stable extension and contraction position of the straight parallel six-bar linkage mechanism, and the positioning accuracy and back and forth of the locking members 60 and 61, which are particularly required when pulling out the heald frame from the loom and installing the heald frame onto the loom, are easy to maintain. The drive screw shaft mechanism is effective in maintaining stable position. Although the effectiveness of such a drive screw shaft mechanism is impaired by the adhesion of fluff on the screw shaft 48, the impediment to effectiveness is reliably eliminated by the measures for preventing the intrusion of fluff in this embodiment.

Moreover, in this embodiment, the closing member of the slit 47a is composed of the linear bodies H1 and H2 that can be easily pushed through by the support shaft 46 of the drive link 45, so that the support shaft can be used when driving the parallel six-bar linkage mechanism. There is almost no frictional resistance between 46 and the closing member. Therefore, it is possible to significantly reduce power loss when transferring warp members such as the warp cut detection device 73 and the like.

Of course, the present invention is not limited to the above-mentioned embodiment. For example, the screw shaft 48 in the above-mentioned embodiment
In place of the ball bearing 49, it is also possible to use a guide rod and a driven ring that is slidably guided by the guide rod, and to slide the driven ring within the cover 47 by an appropriate means.

Effects of the Invention As detailed above, in the present invention, the guide body of the drive mechanism that drives the multi-articulated link mechanism of the passing member transfer means is covered with a covering member, and the driven transmission member is Since the opening formed to allow the drive displacement of the drive mechanism is also closed by a closing member made of a linear body, there is no risk of wind towards the drive mechanism that could lead to malfunction of the drive mechanism and even hinder the smooth transfer operation. In addition to reliably preventing cotton from adhering, since the closing member is constructed of a linear body implanted in the opening, there is almost no frictional resistance with the closing member during drive displacement of the driven transmission member, and the passing member This has the excellent effect of significantly reducing power loss during transfer.
