Description

  The present invention relates to a loom as described in the preamble of claim 1.

  After the warp is consumed and / or the product to be manufactured is finished, it is necessary to take care that the warps do not get entangled with each other. For this purpose, a split loom is used, the entire loom is replaced, or a warp stop motion, a movable device and / or a storage cart in which the heel frame and heel can be integrally attached and detached are used. However, it is known to be careful not to loosen the warp.

  In this regard, it takes effort to replace the loom or part of it, and in the case of a mobile device, it is necessary to leave a spread beam on the loom to maintain the warp position and warp tension, etc. It turns out that there is an inconvenience. This means that a great deal of effort is required to switch warps and / or products.

  In the case of a loom for a narrow fabric, there is known a device that switches the product by removing the heel of the heel frame from the heel guide rod in a direction perpendicular to the traveling direction of the band and in the horizontal direction. This switching operation is very difficult and labor intensive. In addition, the time required for this is considerable.

  Therefore, the present invention solves this, and as described in the characterizing portion of the claims, the present invention is a loom capable of performing warp and / or product switching in a simple means and in a short time. The purpose is to provide.

  By collecting the warp stop motion unit and the spread beam together in the switching device, the warp portion between the warp stop motion unit and the spread beam can be kept constant. Since the holding means is provided in the switching device for receiving the bag frame and the bag, the removal of the product is simplified and can be performed in a short time.

  By connecting the switching device to the support device or the machine base frame, it is possible to simply replace the switching device for product switching, and it is possible to easily replace the product and reduce the switching device space. It can be stored inside.

  A switching unit is formed by combining the warp supply device and the support device with the switching device, and the switching unit and the warp supply device are exchanged and / or stored by connecting the switching unit to the machine base frame, or simply Either the switching device can be replaced and / or stored. By making these exchanges possible, it becomes possible to perform the preparation of the woven fabric substantially more smoothly with respect to warp and / or product switching.

  It is desirable that the switching device comprises a device for guiding and / or fixing the warp, and combining the switching device, the heel frame and the retracted product to form a storage unit and prepare the product for renewal production. I understand.

  If the harness is formed by combining the heel frames, the time required for switching the products is further shortened.

  If the switching device is provided with a comb, the warps parallel to each other can be linked to the comb, and entanglement between the warps can be prevented.

  It is desirable that the warp supply device is formed as a single frame, and that the frame comprises means for receiving the wound body.

The present invention will be described in more detail with reference to the accompanying drawings.

The second separation point 22 is provided between the holder grid 62 and the support device 3. Therefore, the holder grid 62 includes a gripping portion 68, and the holder grid 62 is fixed to the bar 28 (FIG. 6). As shown in FIG. 5, the angle portion 29 is attached to the centering member 34, and the switching device 2 is supported by the support device 3.

  In the loom of the present invention, it is possible to continue production, switch to a previously produced product, and switch to a new product.

  In the case of continuous production, it is only necessary to replace the warp bobbin or the weft bobbin, connect the warp or insert the weft.

  In the case of renewal production, the product stored in the storage unit is inserted into the loom, the necessary switching is performed in the machine part, the warp bobbin and the weft bobbin are replaced, and the warp and the weft are connected.

  In the case of new production, it is necessary to redevelop the machine part for the production of new products. This includes, for example, changing the warp configuration and cam, preparing the corresponding warp bobbins, pulling the warp into the comb, inserting the yarn into the warp stop motion dropper, This includes pulling in, pulling into a kite, preparing wefts, inserting wefts into a weft transporting / inserting device, and the like.

  In the loom of the present invention, the product switching process is divided into preparation and replacement.

  When preparing to switch products, the band is cut off just before the heel. Thereafter, the heel frame moves to the closed shed position and is removed from the drive device, and the warp is pulled out and at the same time, is disposed on the harness suspended by the switching device.

  In this loom, product switching can be performed by exchanging components in two ways. In the first switching method, the storage unit 9 is simply replaced, and in the second switching method, the switching unit 31 including the storage unit 9 is replaced.
