2. Description of the Related Art For example, Japanese Patent Application Laid-Open No.
There is one disclosed in Japanese Patent Publication No. 060. This is
Exchange the cloth roll in the step.

When the woven fabric to be woven in the weaving operation is wound by a predetermined amount on a cloth roll detachably mounted on the loom and becomes full, or just before the full winding state, the loom itself or the central controller. Gives an instruction to replace the cloth roll.

According to the cloth winding exchange instruction, a carrier equipped with an empty cloth winding roll and ready for replacement is called from the carrier store of the factory and arrives at the front of the loom.

A full winding transfer arm assembled to the carrier grips the full winding cloth roll of the loom and moves and mounts from the loom onto the carrier.

An empty transfer arm mounted on the carrier moves and loads an empty cloth roll from the carrier to the loom.

While cutting the woven fabric connected to the full roll wound roll moved and placed on the carrier from the loom, the cut end of the woven fabric on the loom side is wound around the empty roll wound and moved on the loom. .

The full roll of cloth roll is transported to the factory carrier store by moving the carrier.

By the way, in the above-mentioned process, a jet fluid from a nozzle is used to wind the cut end portion of the woven fabric on the loom side around the empty cloth roll that is moved and mounted on the loom.

Problems to be Solved by the Invention As described above, in the structure in which the cut end of the woven fabric is wound around the empty fabric winding roll by the spray fluid from the nozzle, the nozzle and the cutter are moved together in the fabric width direction, Since the cutting end is sprayed onto the upper side of the blank cloth winding roll with the spray fluid at the same time as the cutting of the woven cloth, the entire cut end cannot be uniformly polymerized on the blank cloth winding roll. It is necessary to drag a piping member such as a vinyl tube connected to the supply source, and a large driving force is required to move the nozzle and the cutter in the cloth width direction. And it is difficult to simplify the device.

Also, a plurality of independent nozzles should be fixedly arranged in the vicinity of the empty cloth winding roll, separated from each other in the cloth width direction, and each of the plurality of nozzles should be connected to a pressurized fluid supply source with a piping member such as a vinyl tube. In this case, however, in this case, a large dead space for passing a large amount of piping members near the empty cloth winding roll is required, resulting in a large and complicated structure as a whole.

Means for Solving the Problems According to the first aspect of the present invention, when the woven cloth wound on the cloth winding roll in the winding driving mechanism of the loom reaches a predetermined winding amount, the cloth winding roll is wound. Discharged ahead of the drive mechanism, then move the empty cloth winding roll to the winding drive mechanism, cut the woven cloth connected to the cloth winding roll, and cut the end of the cut woven cloth into the empty cloth winding roll. In a mechanism provided with a winding device for winding, the winding device is provided with a pipe forming a passage of a jet fluid provided along an axial direction of the empty cloth winding roll, and a circumferential wall of the pipe in a cloth width direction of a woven fabric. A separate member that is provided at a distance and is configured with a plurality of injection holes for injecting the fluid from the passage toward the blank-wound roll side, wherein the injection holes further form injection holes longer than the thickness of the pipe. The pipe circumference It is characterized by being configured to be fitted to a wall.

Further, in the invention according to claim 2, the winding drive mechanism is configured by a pair of rotating rollers for mounting a cloth winding roll and winding the woven cloth, while the winding device includes: It is arranged below the pair of rotating rollers, injects a fluid from an ejection hole toward between one side of the rotating roller and the empty cloth winding roll, and the cloth hanging down between them is formed by the rotating roller on one side. It is characterized by having a separation nozzle for separation.

Further, in the invention according to claim 3, the winding drive mechanism is configured by a pair of rotating rollers for placing a cloth winding roll and winding the woven cloth, while the winding mechanism includes: A blowing nozzle that is disposed at a lower portion of the pair of rotating rollers and hangs a cloth hanging from one side of the rotating roller and an empty cloth winding roll toward a second side of the rotating roller from a spray hole. And a guide member for guiding the cloth blown by the blowing nozzle between the rotating roller on the other side and the empty cloth winding roll.

Operation Therefore, according to the first aspect of the present invention, the fluid is ejected from the plurality of ejection holes formed in the pipe, which is a main element of the winding device, to the empty fabric winding roll side. At this time, since the injection hole is longer than the thickness of the pipe and is made of a separate member having high directivity, the cut end of the woven fabric is positioned in the winding drive mechanism of the loom by this injection fluid. It can be securely wound around a cloth roll. In this case, if there is a separation nozzle for ejecting a fluid between the one-side rotating roller and the empty fabric winding roll, the one-side rotating roller and the empty fabric winding are provided. The cloth hung between the roll and the roll is reliably separated from the rotating roller on one side thereof and wound around the empty cloth roll. Further, when the blowing nozzle and the guide member are used in combination as in the third aspect of the present invention, the cloth can be more securely wound around the empty cloth winding roll.
