BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a creel package exchange system used in warping machines and the like.

0002

[Prior Art] A creel used for simultaneously supplying a large number of yarns to a warping machine uses a creel frame, which has multiple pegs in the vertical direction for inserting packages, which are horizontally connected via an endless chain. It is configured so that a large number of them can be connected and circulated. In this creel, when the amount of yarn in the packages lined up on the front side decreases, the packages are sent one after another to the back side, the yarn is cut from the package and connected to the yarn in a new package on the front side, and the remaining yarn remains after the yarn has been cut. A package replacement operation is performed in which the bobbin with thread is removed from the peg and a new package is inserted into the peg.

[0003] In order to automate this labor-intensive package replacement work, the present applicant previously disclosed a package replacement robot (Utility Application No. 1-95534).
No. etc.). This robot targets easy-to-handle cheese packages, and includes a extraction unit that extracts bobbins with residual yarn from each creel frame at once, and an insertion unit that inserts packages at once for each creel frame. The package was rolled and supplied to the insertion unit, and the bobbin with remaining yarn was dropped and discharged from the extraction unit.

0004

However, in the above robot, if the package is a cone package, it is difficult to roll and feed the package to the insertion unit because it does not roll straight. In addition, it is difficult to align the bobbins with remaining threads that have been dropped and discharged in a certain direction and transfer them to the next processing step, making it impossible to handle cone packages.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above problems and provide a package exchange system that can handle cone packages and easily transfer bobbins with residual yarn to the next process. be.

[0006]

SUMMARY OF THE INVENTION The present invention provides a vertical conveyor having pegs disposed adjacent to a creel and circulating in a vertical plane in the same arrangement as the pegs of the creel; It has a positioning member that engages with the peg from below and moves in the axial direction thereof, and a hanger that supports the package or the bobbin with residual thread so that it can be inserted into and removed from the shaft hole behind the positioning member, and the bobbin with residual thread can be inserted and removed. It is equipped with a robot that transfers packages from the conveyor to the creel.

[0007]

[Operation] First, the robot travels to the creel and engages the positioning member with the base of the peg from below to position it.
The positioning member moves the bobbin with remaining thread from the peg to the hanger. Next, it travels to the vertical conveyor, engages the positioning member with the tip of the peg from below to position it, and moves the hanger to insert the bobbin with the remaining thread onto the peg. Next, the package is pulled out from the peg of the conveyor by the same operation and inserted into the peg of the creel.

In particular, since the shaft holes of the package and the bobbin with residual thread are supported by a hanger so that they can be inserted and removed, and these are transferred, it is possible to handle the cone package.

Furthermore, since the bobbin with the remaining thread is inserted into the peg of the vertical conveyor, it becomes possible to easily transfer the bobbin with the remaining thread to the next process in a more orderly manner.

, 12 can be absorbed in the horizontal direction.

Next, the operation of the embodiment will be described. As shown in FIG. 11, the robot 25 first starts operating (S1), travels to the first peg row of the creel 1, and uses the delivery mechanism 24 to extract the bobbin 16 with remaining yarn from the pegs 2 in that row (S1).
2) Next, bobbin insertion position 1 with remaining thread on vertical conveyor 8
4 and inserts (discharges) the bobbin 16 with the remaining yarn into the peg 12 at that position (S3). Next, robot 2
5 travels to the adjacent package extraction position 13 and extracts (loads) the package 6 from the peg 12 at that position (S4
), travels to the first peg row of the creel 1 and inserts the package 6 into the peg 2 of that row (S5).

Next, the robot 25 travels to the adjacent second peg row, pulls out the bobbin 16 with residual thread (S6), travels to the bobbin insertion position 14 with residual thread on the vertical conveyor 8, and inserts the peg 12 at that position. Insert the bobbin 16 with remaining thread into. In the vertical conveyor 8, while the robot 25 reciprocates between the creel 1 and the creel 1, the pegs 12 are sequentially fed one pitch at a time until the pegs 12 are at the bobbin removal position 17 with remaining thread.
The bobbin 16 with remaining yarn is removed from the bobbin 16, a new package 6 is inserted into the peg 12 at the package insertion position 15, and the package 6 is inserted into the package removal position 13.
An empty peg 12 is prepared at the bobbin insertion position 14 with residual thread. Thereafter, the robot 25 sequentially replaces the packages of the creels 1 in the same manner.

To explain in more detail the operation of the delivery mechanism 24 of the robot 25 during this package exchange, first, as shown in FIG. 6(a), only the positioning member 19 is advanced on the side of the peg 12, and then, As shown in (b), the positioning member 19 and the hanger 30 are moved horizontally by the movement of the robot 25, and the positioning member 19 is attached to the peg 12.
and move the hanger 30 forward to approach the tip of the peg 12.

Next, when the positioning member 19 and the hanger 30 are raised and positioned using the above-mentioned elevating mechanism as shown in FIG. As shown in (c), only the positioning member 19 is moved back and the package 6 is pegged to the peg 1.
Just slide it from above 2 onto the hanger 30,
Thereby, the cone-shaped package 6 can be easily removed (loaded) from the peg 12.

When inserting the package 6 into the peg 2, the positioning member 19 is positioned below the tip of the peg 2 as shown by the phantom lines in FIGS. 9 and 10, and the peg is inserted into the groove 32 of the positioning member 19. Once the positioning member 19 and the hanger 30 are moved forward along the peg 2, the package 6 is brought onto the peg 2 (arrow A in FIG. 10). Next, the positioning member 19 and the hanger 30 are lowered (arrow B) to deposit the package 6 on the peg 2, and then only the hanger 30 is moved back and removed from the shaft hole 29 of the package 6 (arrow C). Next, when the positioning member 19 is lowered together with the hanger 30 to a position where it does not interfere with the peg 2 (arrow D), the positioning member 19 and the hanger 30 are horizontally moved to the side of the package 6 as shown in FIG. 9(b). Furthermore, it is only necessary to retreat only the positioning member 19 to the tip of the hanger 30, thereby completing the insertion of the package 6 into the peg 2.

[0028] In the case of the bobbin 16 with remaining thread, the same procedure as the above-mentioned delivery of the package 6 is carried out, but at the bobbin insertion position 14 with remaining thread, the regulating part 18 at the base of the peg 12 is directed upward as shown in Fig. 8. Since it is reversed, its regulation part 1
The bobbin 16 with remaining yarn can be positioned using the end of the thread 8 as a stopper.

In this way, the package 6 and the shaft hole 29 of the bobbin 16 with residual yarn are supported by the hanger 30 so that they can be inserted and removed, and these are transferred. Therefore, unlike the cheese package, the corn package 6, which is not easy to handle, can be used. can be easily handled. Furthermore, since the bobbin 16 with remaining yarn is inserted into the peg 12 of the vertical conveyor 8 in a fixed orientation, it becomes possible to easily transfer the bobbin 16 with residual yarn to the next process in a more orderly manner. .

Note that the package exchange system of the present invention can of course also handle cheese packages. In the embodiment, the hanger 30 is constituted by a rod-shaped member having a U-shaped cross section, but it may be constituted by a pair of rods located on both sides of the pegs 2 and 12.

[0031]

[Effects of the Invention] In summary, according to the present invention, the shaft holes of the package and the bobbin with residual yarn are supported by a hanger so that they can be inserted and removed, and these are transferred.
Since the cone package can be handled and the bobbin with remaining thread is inserted into the peg of the vertical conveyor, it is possible to easily transfer the bobbin with remaining thread to the next process in a more orderly manner.
