[Detailed description of the invention]

[Industrial Field of Application] The present invention relates to a package exchange device for a warper reel in a warping machine. [Prior Art] In the warping machine used in the warp yarn preparation process of Shiki, the yarn is drawn out from a number of yarn feeding package cages inserted into a warper creel (hereinafter simply referred to as creel) and sent to the warper drum. It is wound up. Therefore, on the creel, a very large number of packaged yarns equal to the number of warp yarns of the loom are supported on vertical planes in the upper, lower, and left hex directions at intervals such that they do not interfere with each other. For example, several hundred package cages are neatly inserted and supported on pegs on the creel. The packages doffed from the winder in the previous process are manually fed one by one by an operator to the creel. [Problems to be Solved by the Invention] As mentioned above, when an operator supplies package cages, depending on the height of the creel, the worker may have to use a trolley or go back and forth between the package storage area and the creel several times. Furthermore, the weight of the package is 3 to 5 kg, making the work difficult and dangerous. Furthermore, the yarn layer of the package is soiled by the operator, resulting in a decrease in yarn quality. The present invention aims to solve the above problems. [Means for solving the problem] The present invention provides an elevating body provided on a movable trolley;
and a package support arm provided on the elevating body, the package support arm having a plurality of package support devices spaced apart along its longitudinal direction, and supported rotatably around two orthogonal axes. The support arm is raised and lowered and rotated to replace a plurality of yarn feeding package cages and empty take-up tubes at once with respect to a plurality of vertical or horizontal peg groups of a warper creel in which a large number of pegs are aligned and fixed in the vertical and horizontal directions. This is a package exchange device characterized by the following: [Operation] The packages conveyed on the conveyor are aligned equally to the pitch between the pegs of the creel via the conveyance medium, and when a predetermined number of packages are aligned, the support arm of the exchanger rotates to follow the group of aligned packages. The aligned packages are collectively supported by each package support device provided separately on the arm, and are transferred to the creel side by rotation and/or elevation, and are moved to a predetermined position in the vertical or horizontal direction of the opposing creel. The plurality of package cages are simultaneously inserted into the peg group. In addition, if empty take-up tubes are inserted into the pegs of the creel at this time, multiple empty take-up tubes can be removed in advance from the vertical or horizontal peg group by the same movement of the support arm. he,
It is transferred to the empty take-up tube conveyor. [Examples] Examples of the present invention will be described below with reference to the drawings. In FIG. 2, an example of a package transport system is shown. For example, multiple automatic winders 1a~

The cam groove 54 is formed between an engagement side 54a with the cam roller 50a and an exit side 54c,
When the cam drum 52 rotates once in the direction of arrow 55, the cam roller 50a at the entry side position moves to the exit side 50.
The cam groove 54 of the drum is formed such that the distance P2 in the direction of the axis 53 between them is equal to the pitch P2 between the peg rows of the creel 5. Therefore, for example, with the cam roller 50a positioned at the entrance side 54a in FIG.
When the roller 54a rotates once, the roller 54a moves in the direction of the arrow 56 by a pitch P2, that is, the creel 5 moves one pitch P.
It will take 2 minutes to move. At this time, the next roller 5
0b reaches the entrance side 54a, and pitch feeding of the creel is performed. In addition, in FIG. 3, the peg rows 18a and 18f on both sides of one creel 5 are connected to the frame end 16a,
The creels 5a and 5 are formed at a distance (P2/2) from each creel 16b, and therefore, as shown in FIG.
When the pegs are aligned in one line, the pitch between the peg rows becomes constant P2 over all the creels, and the intermittent rotation of the cam drum 52 allows pitch feeding of all the creels. In addition, when restarting the above steps (a) and (b), in this case, as shown in the third diagram, the positions of the pegs in rows 18b and 18c are shifted up and down by half a pitch (P1/2), and the pegs in row 18c are shifted vertically by half a pitch (P1/2). Because of the upper position, the height of arm 704 in the vertical position in the position of FIG. 12A is raised a distance (P1/2) higher than in the previous operation. That is, the lifting amount is determined by the movement of the swing arm 713 by the rotation of the motor M1 in FIG. In FIG. 1, package K1 at alignment position A
~During the time when K8 is hung on the arm of the exchanger 700 and fed to the creel, and further during the time when the empty take-up tube of the next creel row is removed, the empty trays t1 to t8 at the alignment position B are When the stopper 42 is released, the packages are delivered in the direction of the arrow 43, and at the package transfer position 300, new trays T1 to T8 with packages inserted therein are subjected to the pick-up process in the same manner as described above and are transferred to the alignment position A. Each of the above-mentioned devices is controlled so that the Therefore, the next new package can already be lined up at the alignment position A during one cycle of the package exchange device for removing an empty winding tube and supplying a new package, thereby reducing waiting time in the exchange device 700. This makes it possible to feed a large number of packages to the creel extremely efficiently. In the above embodiment, the alignment station ST
As mentioned above, as long as the packages in No. 1 are lined up by trays T1 to T8 having a constant diameter D, the packages for one line of the creel will be lined up at a pitch equal to the pitch between the upper and lower pegs of the creel. This means that even if the diameter of the yarn layer of the package itself changes depending on the yarn type and yarn amount of the yarn supply package due to a change in lot or process, the position of the center hole of the package on the aligned tray will always remain the same. Therefore, the package support arm of the exchanger 700 can simply perform the same operation, which simplifies the control of the exchanger. In addition, in the above embodiment, the alignment state of the packages at the alignment position A was set to be one line, but this does not apply to the third
This is related to the fact that in the illustrated creel 5, package exchange is performed in each row surrounded by the two-dot chain line 44.
When replacing packages for each group of pegs arranged in a zigzag pattern as shown in 5 and 46, it is natural that the trays of the package conveyor and the empty winding tube conveyor on the alignment station side should match the arrangement of pegs. Similarly, the conveyor is wide enough to be suitable for being arranged in a zigzag pattern, and furthermore, the mounting position of the package chuck piece provided on the arm 704 itself of the exchange device 700 is replaced with an arm arranged in a zigzag pattern. Therefore, even in each of the above cases, the package can be replaced in the same cycle as described above. [Effects of the Invention] As described above, in the present invention, the package support arm is provided with a plurality of package support devices spaced apart along the longitudinal direction, and is rotatable around two orthogonal axes. Replacement work such as inserting package cages and removing empty take-up tubes can be done all at once for multiple peg groups in the vertical or horizontal direction on the warper reel, thereby greatly reducing the time spent on replacement work. be able to. In addition, the workability is good, the worker is not forced to perform dangerous work, and the thread layer of the package is not soiled by the worker, resulting in a decrease in the quality of the thread. In addition, the exchange device itself is made more compact, contributing to space savings.
