[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a package transfer device for receiving a package of partially drawn yarn carried by an overhead traveling carrier and transferring it to a robot that transfers it to a drawing false twisting machine.

[0002]

[Prior art]

 At a synthetic fiber draw false twisting factory, a package of partially drawn yarns packed in multiple stages is loaded into a pallet, and the draw false twisters are lined up and lined up at each stage by a ceiling conveyor that runs on rails installed on the ceiling. It is transported by dropping it on the mounting table placed on the side of the. Three pegs are erected on this mounting table and can swing at right angles so that they can face both upward and sideways. At this time, the three packages carried by the ceiling carrier are inserted into these pegs from above.

By the ceiling transfer device, the mounting table in which the package is attached to each peg swings at a right angle, and supports the package in a state in which the package is directed to the side. The packages on this mounting table are extracted one by one by a clear robot, and the packages are transported to the pegs of the creel of the draw false twisting machine that requires the packages by traveling of the creel robot, and the empty bobbin of the creel is extracted and inserted. Put on and repeat the same operation to supply all three packages on the mounting table to the creel. When three packages are taken out, a request signal is output to the overhead traveling carrier and the empty mounting table is turned over 90 degrees again and the pegs are turned upward. A package conveyed by an overhead traveling carrier that travels based on the request signal is inserted into this peg, and this process is repeated to draw a partially drawn yarn package carried into a drawn false twisting factory. Are going to supply.

[0004]

In the above apparatus, a mounting table of a transfer station for inserting and mounting a package conveyed by an overhead traveling carrier is provided. Then, when all three packages mounted on the mounting table become empty, a request signal is output to the overhead traveling carrier and the mounting table is turned upside down by 90 degrees so that the overhead traveling vehicle can mount three packages on the mounting table. After supplying the package, the mounting table rotates 90 degrees toward the robot. The robot takes out the packages one by one and supplies them to the creel one by one. At this time, if the robot cannot supply the package to the mounting table that outputs the next request signal within the time when the robot supplies the third package to the creel, the robot waits, and the transfer system Overall efficiency is reduced.

On the other hand, in an overhead traveling carrier that circulates on rails installed on the ceiling, a plurality of overhead traveling carriers travel on the same rail to transport packages, and the above-described mounting table is provided. The above packages are supplied to multiple transfer stations. Such an overhead traveling vehicle needs to be supplied to a large number of stations because it is necessary to appropriately maintain the front and rear intervals. In particular, when the package request signals are output simultaneously on each mounting table, the drawing false twisting machine that has to wait for a long time is generated due to the limitation of the package supply capacity of the overhead traveling transport vehicle, and the operating efficiency of the factory is reduced. There was a flaw.

[0006] Therefore, an object of the present invention is to provide a creel robot with a high transfer efficiency without causing a waiting time.

[0007]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a package including a mounting table having a plurality of pegs for mounting the packages on the mounting surfaces forming the respective sides of the frame, and a driving device for rotating the mounting table by 90 degrees. The transfer device is configured so that the clear robot does not have a waiting time and the package transfer device has a high supply efficiency.

[0008]

[Action]

 Since the present invention is configured as described above, the package transported by the overhead traveling transport vehicle is an empty peg which is positioned on the upward mounting surface of the mounting surfaces forming each side of the square frame. It is inserted and placed. Then, the mounting table is rotated 90 degrees, and the package inserted in the peg is turned sideways. The creel robot conveys the packages facing the side to the creel one by one, and conveys all the packages attached to the pegs to the creel, and the loading table with only empty pegs is re-mounted on the loading table. It turns downward by rotating in the same direction by 90 degrees. On the other hand, when the creel robot starts to convey the package on the side facing the loading surface, it runs on the ceiling against the upward facing empty peg that has rotated from the loading surface on the other side surface to the upper surface. The transport vehicle issues a signal to the overhead traveling transport vehicle to insert and place the package in the same manner as above, and based on this signal, the overhead traveling transport vehicle transports the package and waits for the placement. Attach to the peg on the surface. Therefore, in the overhead traveling transport vehicle, the packages may be attached to the pegs facing upward at least until all the packages facing the side are transported one by one by the creel conveyor.
