Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a mechanism device having heald frame transfer means for mounting a plurality of heald frames on a loom and removing the heald frames from the loom collectively. The present invention relates to a mounting guide means for a heald frame transferred to a loom.

[Prior Art] In the work of attaching a warp beam to a loom and passing the warp through the weaving apparatus side (machine work), a new warp beam is taken into consideration in consideration of the shortening of the work leading to an improvement in the operating efficiency of the loom. An operation procedure in which the warp is inserted through a plurality of heald frames in advance before mounting is generally adopted. By adopting such a work procedure, it is not necessary to tie a new warp beam side warp and a woven cloth side warp one by one on the warp path from the warp beam on the loom to the heald frame. Time can be reduced.

A device for transporting and transferring a warp beam and a heddle frame into which a warp thread is inserted is disclosed, for example, in Japanese Patent Publication No. 57-53899. In this device, a horizontally expandable and contractible arm is supported by a pair of lifting columns, and a hook member is connected to the ends of both arms, so that the upper frame of the heald frame and the upper carrier rod for heald tensioning are connected to each other. A plurality of heald frames are collectively hung and suspended by inserting the hanging member therebetween.

[Problem to be Solved by the Invention] However, the guide groove of the channel-shaped guide member for guiding the vertical movement of the heald frame is only slightly larger than the width of the heald frame, and a plurality of heald frames are collectively hung. It is difficult to arrange the heald frame at a predetermined position vertically above the upper end insertion opening of the guide groove only by the front and rear movement of the hanging member that is suspended. Therefore, it is inevitable that a plurality of heald frames must be manually aligned one by one with respect to the upper end insertion opening one by one, and automatic installation of the heald frames by the mechanism device becomes impossible.

[Means for Solving the Problems] Therefore, in the present invention, a guided member that defines a heald frame interval is attached above and below the center of each heald frame, and is guided by both left and right channel-shaped guides or the same guide. Of the left and right pairs of upper end insertion holes formed in the channel-shaped movable mounting body, the frontmost inner side surfaces of the left and right pair of frontmost upper end insertion holes are respectively located on the vertically upper side by extending the front surfaces upward. A pair of left and right positioning members capable of positioning the left and right front surfaces of the heald frame are disposed on the transfer path in the front-rear direction of the heald frame.

[Operation] When a plurality of heald frames are moved forward above the upper end insertion port by a transfer operation of a device for hanging and suspending a plurality of heald frames at a time, the left and right front sides of the frontmost heald frame. Abut on a pair of left and right positioning members. This facilitates front-rear positioning of the foremost heald frame with respect to the foremost upper end insertion port. Further, since the interval between the heald frames is defined by the guided member in the mounting interval in the loom, the positioning of the other heald frames in front and rear with respect to the upper end insertion opening is also determined.

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

Jack levers 5 and 6 rotatably supported by forked brackets 3 and 4 erected on both left and right side frames 1 and 2 of the loom are rotationally biased by springs 7 and 8, and At the lower ends of the hanging ropes 9 and 10 connected to the levers 5 and 6, channel-shaped movable mounts 11 and 12 are hung and suspended via hanging connecting members 13 and 14, respectively. A reciprocating drive mechanism including a cam 15 and a cam lever 16 that rotates in synchronization with the rotation of the machine base is installed on one side of the side frame 1, and pull-down ropes 17 and 18 connected to the cam lever 16 are hooked connecting members. They are connected to the lower ends of the movable mounting bodies 11, 11A, 12, 12A via 19, 20. Accordingly, the rotation of the cam 15 causes the movable mounting bodies 11, 11A, 12, 12A

The rear surfaces of the positioning plates 24, 25 are set on a plane including the front side surfaces of the mounting grooves 11a, 12a of the foremost movable mounting bodies 11A, 12A, and the distal ends of the positioning plates 24, 25 are movable mounting bodies 11, 11A. , 12,12A are extended to the inside.

Now, when replacing the heald frame with the replacement of the warp beam, the warp beam transfer means for mounting the full warp beam on the loom and removing the empty warp beam from the loom, and the warp of the warp beam are inserted. There is used a mechanism device comprising heddle frame transfer means having a pair of hook members 26 and 27 capable of suspending the heald frame at a time. The plurality of heald frames 23, 23A, which are collectively latched and supported by the latching members 26, 27, are transferred in close contact with each other at the guided members 33A, 33B. Then, the heald frames 23, 23A are collectively advanced to the positions above the movable mounts 11, 11A, 12, 12A as shown by the chain lines in FIG. 1 and the solid lines in FIG. Moved and then moved down. The plurality of movable mounts 11, 11A, 12, 12A are stopped at the vertical position at which the mounted plurality of heald frames are in a leveling state.

The front ends of the left and right positioning plates 24, 25 are set on the forward movement path of the heald frames 23, 23A, and by moving the heald frames 23, 23A forward, the left and right side stays 23a, 23a, 23b comes into contact with the distal ends of the positioning plates 24 and 25. If the hook members 26, 27 are moved forward until the front heald frame 23A comes into contact with the positioning plates 24, 25, the front heald frame 23A is
Even if 6, 27 goes a little too far, it will be stopped by the positioning plates 24, 25. This stop position is vertically above the mounting grooves 11a and 12a of the foremost movable mounting bodies 11A and 12A, and the heald frame 23A is
If it is within the distance between a and 12a, the heald frame 23A can be moved down by moving the hook members 26 and 27 down.
