Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a loom device used to attach and detach a warp beam and a member through which the warp threads are passed from the loom to and from the loom. It is.

(Prior technology) In the work of attaching a warp beam to a loom and passing the warp threads to the weaving equipment side (the loom is a work in progress), a new warp beam was developed in consideration of reducing the time required for the above work, which would lead to improved operating efficiency of the loom. A common procedure is to insert the warp threads through a plurality of heald frames before installing them. By adopting such a work procedure, there is no need to tie together the warp threads on the new warp beam side and the warp threads on the woven fabric side one by one on the warp path from the warp beam to the heddle frame on the loom. It is possible to shorten the time required.

An example of a device for transporting and transferring a warp beam and a heald frame through which its warp threads are inserted is disclosed in Japanese Patent Application Laid-Open No. 52-49358. In this device, a pair of arms that can be extended and contracted in the horizontal direction are attached to the lifting column, and a latching member is connected to the tip of both arms.The latching member allows the heald frame to be hung at once. It is supposed to be lowered.

(Problem to be Solved by the Invention) However, the height position of the heald frame varies depending on the weaving conditions or the type of heald frame, and this difference in the heald frame height position and the height of the ceiling of the weaving room In the above-mentioned conventional machine mechanism, it may not be possible to cover the difference in the height position of the heald frame only by raising and lowering the lifting column in the device, and the permissible range of the transfer operation of the hanging member for the difference in the height position of the heald frame is Restrictions and difficulties in smooth transfer of heald frames are unavoidable.

Structure of the Invention (Means for Solving Problems) Therefore, in the present invention, a pair of hanging members capable of collectively suspending a plurality of heald frames through which warp threads of a warp beam are inserted are adjustable in the vertical mounting position. The loom equipment consisted of a heald frame transfer means provided for the loom, and a warp beam transfer means for attaching the full warp beam to the loom and removing the empty warp beam from the loom.

(Function) That is, by adjusting the mounting positions of the pair of latching members according to the height position of the heald frame, the transfer operation of the latching members is regulated within the range that passes through the transfer of the heald frame, Smooth engagement between the hanging member and the heald frame is possible while avoiding contact between the ceiling of the weaving room and the heald frame transfer means.
