Description

Description: Object of the Invention (Industrial application field) The present invention relates to a looming device used when a warp beam and a member through which a warp passes are attached to and removed from a loom. .

(Prior Art) In the work of attaching a warp beam to a loom and passing the warp to the weaving device side (mechanical 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 heald frame and a reed before mounting is generally employed. That is, by adopting such an operation procedure, it is not necessary to tie the warp on the new warp beam side and the warp on the woven fabric one by one on the loom, and the time for the machine work can be reduced.

Japanese Patent Publication No. 57-53899 discloses an example of a device for mounting a warp beam and a threading member such as a heald frame, a reed or a dropper box through which a warp thread is passed. In this machine, the warp beam is mounted and supported on a hand cart, and the heald frame is suspended and supported by a heald frame suspension arm that is vertically erected on the carriage. The heald frame suspension arm can extend and contract between the bogie and the loom. The warp beam and the threading member are mounted on the bogie in the same order as the mounting positions of these members on the loom, and the transfer from the bogie to the loom is facilitated.

(Problems to be Solved by the Invention) However, in order to transfer the warp beam and the passing member from the bogie side to the loom side, the entire bogie must be brought closer to the loom side. As disclosed in FIG. 3, it is necessary to provide a notch groove on the bogie side so as not to interfere with the frame on the loom side, and to introduce the frame on the loom side into the groove. Generally, the transport direction of the bogie is orthogonal to the notch groove, and therefore, in order to move the bogie closer to the loom, the direction of movement of the bogie must be changed from the transport direction to the orthogonal direction. In order to change the moving direction, the direction of the guide of the cart must be changed. However, when the cart is stopped, the caster changes direction due to a very heavy warp beam and the load of the cart. Etc. are likely to be damaged. In addition, the configuration in which the bogie on which the heavy warp beam is placed is manually moved causes heavy labor for the operator, and furthermore, there is a problem that interference between the loom side and the bogie side cannot be reliably avoided.

SUMMARY OF THE INVENTION In view of the above-described problem of the hand-operated hoisting pee bogie, an object of the present invention is to travel a passage provided between looms in a weaving factory in which a large number of looms are installed, and require a loom.

A control device for controlling each driving device of the auxiliary table, the warp beam transfer means and the passing member supporting means is provided on the automatic guided vehicle.

(Operation) According to the present invention, when the automatic guided vehicle travels along the guide portion installed on the floor, and is stopped at the mocking work position for the loom, the auxiliary table is moved to the loom by the reciprocating drive device. Moved towards. As a result, the warp beam transfer means and the passing member support means on the auxiliary table are arranged at a predetermined machined position on the automatic guided vehicle, and the empty warp beam and the passing member on the loom are moved to the warp beam transfer means and the passing member. It is transferred to the member supporting means. After the transfer from the loom side to the auxiliary platform side, the auxiliary platform returns to the standby position on the automatic guided vehicle, and the automatic guided vehicle is moved to a predetermined location. When the automatic guided vehicle on which the full warp beam and the warp member passed through the warp are mounted reaches the predetermined mechanism work position,
The auxiliary table is pushed out from the automatic guided vehicle side to the loom side, and the warp beam transfer means and the passing member supporting means on the auxiliary table are arranged at the machine setting position as described above. And
After the full warp beam and the threading member on the auxiliary table are transferred to the loom side, the auxiliary table returns to the standby position on the automatic guided vehicle, and the automatic guided vehicle is moved to a predetermined location.
