Description

[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention is characterized in that a full warp beam is installed in a loom in place of an empty warp beam, and the loom mechanism for passing the warp threads to the weaving device is installed before work. The mechanism is related to the preparation method.

(Prior art) A full warp beam beam is installed in the loom instead of an empty warp beam, and the loom mechanism that passes the warp threads to the weaving device side is designed to reduce the time required for the above-mentioned work on the loom, which will improve the operating efficiency of the loom. A work procedure is generally adopted in which the warp threads are passed through warp passing members such as heald frames and reeds before the full warp beam is installed. For example, as shown in FIG. 11, a full warp beam 41 and a warp '
Dropper device 42 for thread breakage detection, heald frame 43, and reed 44
A through member called M is placed on the circumferential surface of the full warp beam 41.
The full warp beam 41 and the through members 42, 43.4 are tied together with 2S.
4 is stored on the floor or suspended as shown in the figure. That is, by adopting such a work procedure, it is no longer necessary to tie the warp threads on the full 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 dropper device 42 on the m machine, Machine work can shorten work time.

(Problems to be Solved by the Invention) However, in the preparation method, the mechanism for assembling the warp threading members such as the heald frame 43 and reed 44, through which the warp threads T are passed, into the full warp beam 41 is not suitable for the bending shape of the warp threads T. When the full warp beam 41 and the warp threading members 42, 43, 44 are assembled and separated, the warp threads may become entangled with each other, or the warp threads may be damaged due to rubbing against the warp threading members 42, 43, 44. Inevitable. In addition, when the strings 45 are used to gather the warp yarns, the members 42, 43, and 44 are likely to be displaced, causing damage to the warp yarns, and the upper string 45 itself disturbs the warp layer on the full warp beam 41, further promoting intertwining of the warp yarns. Moreover, the assembled state of each member 42, 43, 44 that brings about the bending and holding shape of the warp threads T is the full warp beam 4.
1. It obstructs the automation of mechanical means for attaching the threading members 42, 43, 44 to the loom.

Structure of the Invention (Means for Solving the Problems) Therefore, in the present invention, an empty warp beam removed from a loom and at least warp members such as a heald frame and a reed through which the warp threads are passed are transferred from a carrier to a pedestal. Transferring at least the through-hole member to a predetermined full warp beam transfer work position, moving and arranging the cradle to a predetermined full warp beam transfer work position, placing the full warp beam on the cradle at the same transfer work position, and In this state, the cradle is moved to a predetermined warp connection work position, and at the same connection work position, the warp on the full warp beam side and the warp on the warp threading member side are connected by the warp connection means. A method of preparing the machine via the cradle was adopted, in which the cradle was moved and stored at the stock position.

(Function) That is, among the empty warp beams removed from the loom and the warp threading member through which the warp threads are passed, only the empty warp beam is replaced with a full warp beam, and the warp threads on this full warp beam side and the warp threading member are replaced with a full warp beam. The preparation for connecting the side warp threads is carried out on a pedestal that moves between these preparatory work positions, and the full warp beam and the warp threading member through which the warp has been threaded are placed on the pedestal. It is stored in a predetermined stock position in a state where it is stored. Therefore, the warp beam replacement work and the warp thread connection work on the pedestal that stably holds the warp beam and the warp threading member are smooth, and the coordination between the work is extremely good. Further, since the full warp beam and the warp threading member are stored while being placed on the pedestal, unlike the conventional case where the warp threads are stored together using strings, the warp threads do not get entangled with each other and the warp threads are not damaged.

Moreover, the full warp beam and the through member can be placed on the pedestal at 4
The a-storage mode facilitates automation of the mechanical means for attaching each of these members to the loom.

Of course, the present invention is not limited to the above-mentioned embodiment. For example, the empty warp beam lowering work position U2 in the above embodiment may be omitted, and the empty warp beam transfer work position U2 may be omitted.
In 1, only the through member may be transferred to the pedestal. Of course, in this case, it is necessary to thread the warp threads on the warp threading member side. In addition, the rough weft insertion work in the above embodiment is omitted, and the warp threads of the full warp beam are stored in a storage shelf while being passed through a reed, and each of the above-mentioned machine parts is placed at the working position U.
1 to U6 may be installed linearly, or a chain conveyor or the like may be used as a storage means for the cradle. Furthermore, casters etc. are attached to the pedestal so that it can be moved directly,
The present invention can also be applied to the preparation of a loom in a loom that employs an optical detection device as a warp cut detection means instead of a dropper device as a warp threading member.

Effects of the Invention As detailed above, according to the preparation method of the machine mechanism of the present invention, the warp beam exchange work and the warp thread connection work are performed smoothly, and the coordination between each work is extremely good. A configuration that does not cause damage to the warp yarns and stores the full warp beam and warp threading members in 8 places on the pedestal is such that each of these members can be stored in 11 places.
This has the excellent effect of facilitating the automation of mechanical means for mounting on a single aircraft.
