DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a full and empty pipe transfer device in a spinning machine of the present application will be described with reference to the drawings. As shown in FIGS. 1 and 2, a transport rail 2 is arranged along the base of the spinning frame 1. The transport rail 2 is disposed below the machine base by a bracket 2a, and has a transport portion 3 from the gear end GE end portion to the out end OE end portion, and a transport portion 4 that goes around the gear end GE end portion and the out end OE end portion. And are connected endlessly. A plurality of peg trays 5 into which empty and empty tubes are inserted are arranged in a line on the transport rail 2 so that they can be guided. As shown in FIGS. 3 and 4, an engaging recess 7 for engaging and disengaging the catch 6 is formed at the bottom of the peg tray 5, and a peg 8 is formed to project upward from the center of the peg tray 5. Most of the transfer portion 3 and the transfer portion 4 of the transfer rail 2 have the cross-sectional shape shown in FIG. 3 except the transfer device 14 in FIG. 3, and guide walls 9 for guiding the bottom surface and the side surface of the peg tray 5. A guide slit 12 is provided which is provided with 10 and which is continuous with the upper wall 11 for the peg 8 projecting above the peg tray 5. The transport rail 2 is provided with a lower wall 13, and the lower wall 13 is fixed to the machine base via brackets 2a at appropriate positions so as not to interfere with a transfer device 14 described later. The guide wall 9 that guides the bottom of the peg tray 5 is full, and the catch 6 of the empty pipe transfer device 14 is provided.
Is formed with a bottom slit 15 capable of appearing and disappearing.

As shown in FIG. 2, below the carrying portion 3 of the carrying rail 2, a conveyor rod 16 is provided along the carrying portion 3 in the machine longitudinal direction. This conveyor rod 1
6 is configured by connecting the ends of a plurality of rods 17 with a connecting bolt 19 by a rod connecting tool 18. One end of the conveyor rod 16 is connected to a cylinder 20 provided on the out-end OE side of the machine base, and the cylinder 20 enables the conveyor rod 16 to move in the machine longitudinal direction. As shown in FIGS. 3 and 4, the rod connector 18 for connecting the conveyor rod 16 at a predetermined position of the machine base is a catch which is engaged with and disengaged from the engaging recess 7 formed in the lower surface of the peg tray 5. 6 is swingably attached by a pin 21 inserted between the rods 17, 17, and a torsion spring 23 for urging the front end 22 of the catch 6 in the catch 6 projecting direction is fitted on the pin 21 to catch it. The transfer device 14 is provided between the rod 6 and the rod connector 18.

Next, the operation will be described. When the conveyor rod 16 is moved forward by the cylinder 20, the transfer device 14 disposed in the rod connector 18 is biased in the catch projecting direction by the spring force of the torsion spring 23 and projects from the bottom slit 15 to project from the peg tray 5. The front end 22 of the catch 6, which is engaged with the engagement recess 7 formed on the lower surface of the peg tray 5, conveys one peg tray 5 in the transport direction (rightward in FIG. 2). After that, when the conveyor rod 16 moves backward, the catch 6 moves in the direction opposite to the transfer direction, and the front end of the catch 6 swings against the lower surface of the peg tray 5 against the spring force of the torsion spring 23 to engage the concave portion of the peg tray 5. When the front end 22 of the catch 6 is engaged with the engaging recess 7 of the peg tray 5 following the peg tray 5 which was engaged earlier, the front end 22 of the catch 6 is disengaged from the peg tray 5. By repeating this operation, the peg trays 5 are sent one by one in the transfer direction.

As described above, since the catch is swingably attached to the rod connector, the catch attaching member is unnecessary for attaching the catch to the conveyor rod, and the catch attaching member is attached to the conveyor rod with bolts or the like. No more machining is required, and the number of machining is reduced. In addition, since the torsion spring is used to urge the catch attached to the rod connecting member in the catch projecting direction to engage the catch front end with the engaging recess formed on the lower surface of the peg tray, it is not necessary to use a conventional transfer device. Compared to the one that uses the sliding resistance of the weight slidably provided on the transport rail to urge the catch in the catch protruding direction, the number of parts that make up the transfer device is smaller and the structure is simpler. Time will be shortened. Further, since the number of parts and the working time are reduced, the manufacturing cost can be reduced. Although the torsion spring is used in this embodiment, the present invention is not limited to this, and the catch rear portion and the conveyor rod may be connected by a pull spring to urge the catch front end.

[0010]

As described above, according to the full and empty pipe transfer device of the present invention, the catch is swingably attached to the rod connector, and the front end of the catch is biased by the spring in the catch projecting direction. Therefore, unlike the conventional transfer device, the catch mounting member and weight for mounting the catch are unnecessary, the number of parts is reduced, the number of parts processed and the assembly time are reduced,
It has a simple structure and is inexpensive.
