Description

[Detailed Description of the Invention] Purpose 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. be.

(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 into the heald frame and reed before installing the heald. That is, by adopting such a work procedure, it is no longer necessary to tie the warp threads on the new warp beam side and the warp threads on the woven fabric side one by one on the loom, and it is possible to shorten the work time of the loom workers.

Japanese Patent Publication No. 57-53899 discloses an example of a device for mounting a warp beam and warp members such as a heald frame, a reed, or a dropper box, through which the warp threads are passed, on a loom. In this mechanism, the warp beam is installed and supported on a hand truck, and the heald frame is suspended and supported from a heald frame suspension arm that is vertically movable on the truck. The heald frame hanging arm can be extended and retracted between the cart and the loom. The warp beam and the through member are mounted on the truck in the same order as the mounting positions of these members on the loom, making it easy to transfer them from the truck to the loom.

(Problems to be Solved by the Invention) However, in order to transfer the warp beam and the through member from the truck to the loom side, the entire truck must be brought closer to the loom, and for this purpose, Figures 2 and 3 of the above publication show that As disclosed in , it is necessary to provide a cutout groove on the cart 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 direction of carriage of the carriage is perpendicular to the notched groove, and therefore, in order to bring the carriage closer to the loom, the direction of movement of the carriage must be changed from the direction of carriage of the carriage to the direction perpendicular to the direction of carriage. In order to change the direction of movement like this, it is necessary to change the guide direction of the casters of the trolley, but changing the direction of the casters when the trolley is stopped is difficult due to the extremely heavy warp beam and the load of the trolley. This can easily lead to damage to the mechanism, etc. Moreover, the configuration in which a cart carrying a heavy warp beam is manually moved requires a lot of effort for workers.
'fi Ifjr, and there is a problem that interference between the loom side and the cart side cannot be reliably avoided.

Structure of the Invention (Means for Solving Problems) Therefore, the present invention provides a warp beam transfer means for attaching a full warp beam to a loom and removing an empty warp beam from the loom, and a warp beam transfer means for attaching a full warp beam to a loom and removing an empty warp beam from the loom; At least a heald frame and a through member supporting means for supporting a through member such as a reed are installed on an auxiliary stand, and the auxiliary stand is movable reciprocally between a standby position on the transport vehicle and a position where the mechanism is placed. The machinery was placed on a transport truck to form a device.

(Function) That is, when the loom of the carrier for the loom is in the working position, the auxiliary platform is pushed out from the carrier to the loom. As a result, the warp beam transfer means and the through member support means on the auxiliary platform are moved, the predetermined looms on the cart are placed in position, and the empty warp beam and the through member on the loom are moved to the warp beam transfer means and the through member support means. It is transferred to the thread member support means.

After the transfer from the loom side to the auxiliary stand side, the auxiliary stand returns to the standby position on the transport cart, and the transport cart is moved to a predetermined location. When the transport cart carrying the full warp beam and the warp threading member threaded through it reaches the working position of the predetermined loom, the auxiliary platform is pushed out from the transport cart side to the loom side, and the process is carried out in the same manner as above. Then, the warp beam transfer means and the through member support means on the auxiliary stand are placed in position. After the full warp beam and the through-hole member on the auxiliary stand are transferred to the loom, the auxiliary stand returns to the standby position on the carrier, and the carrier is moved to a predetermined location. In this way, by dividing the two moving elements of transport and transfer into the transport cart and the auxiliary platform, the transport cart can position the predetermined loom for the loom to the working position with high precision, and this excellent After positioning, the auxiliary stand can be moved to the loom without interfering with the loom. Therefore, the warp beam transfer means and the through member support means are arranged in a relationship suitable for transfer with respect to the loom,
