Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a package supply system to a warper creel in a warping machine.

[Conventional technology]

In the warping machine used for the warp yarn preparation process of the loom,
Yarns pulled out from a large number of yarn feeding packages inserted into a warper creel (hereinafter simply referred to as creel) are wound onto a warper drum. Therefore, on the creel, a very large number of packages equal to the number of warp threads of the loom are supported on vertical planes in the vertical and horizontal directions, with intervals such that the threads to be released do not interfere with each other. A hundred packages are neatly inserted and supported on the pegs on the creel.

In this way, the package doffed from the wine goo in the previous process is fed to the reel by the worker.
Each piece is made by hand.

[Problem that the invention seeks to solve]

As mentioned above, when workers supply packages, depending on the height of the creel, they may need to use a trolley, move back and forth between the package storage area and the creel many times, and even have to use pan cages weighing 3 to 5 kg. The work is heavy, difficult to work with, and dangerous. Additionally, the yarn layer of the package gets dirty by the operator, resulting in a decrease in yarn quality.

Furthermore, the ends of the yarn at the end of the winding of the package wound by the automatic wine goo in the previous process are in close contact with the outer peripheral surface of the yarn layer. When pulling out the thread, it is necessary to search for the end of the thread and pull it out, which is a tedious task. Moreover, searching for the thread ends of each of the thousands and hundreds of pan cages results in a large amount of lost time.

The present invention aims to solve the above problems.

[Means to solve the problem]

In the present invention, a yarn end pulling device for picking out the yarn end of the package is disposed midway along the conveyance path of the yarn feeding package supplied to the warper creel, and the yarn end pulled out in advance is separated from the yarn layer. It is conveyed and supplied to the creel section in the same state.

Next, as the cart moves a certain amount in the direction of the arrow (41), that is, toward the creel (5), all the packages (K1) to (X8) on the arm (704) are inserted into the pegs on the creel (5) side. As the trolley returns to the position shown in Figure 130, the yarn end that had been held by the pressing plate (740) in Figure 8 also becomes free, and either remains attached to the end surface of the package or hangs down from the surface of the package due to gravity. The state will be as follows. This guarantees that when the creel supplied with the package is positioned at its original warping station, the work of pulling out the yarn end or joining the yarn is simplified. In other words, the yarn end can be easily found.

In this way, when the pancage replacement work in the - row (18b) of the creel (5) in Fig. 1.3 is completed, the arm (704) remains in the state shown in Fig. 13D, and the creel (5) is replaced. When the next row (18G) is moved by one pinch (P2) and positioned at the pancage exchange position, the above steps (a) and (0) are started again.

An example of the intermittent feeding mechanism of the pinch (P2) in the alignment station (B) of the creels (5a) to (5n) is shown in FIGS. 3.4 and 14. That is, cam rollers (50a) to (50f) are rotatably supported on the upper frame (17a) of the creel (5) for each position of the peg row, and on the rail (8) side, the cam rollers are fixed to the cam rollers. , a removable cam groove drum (52) is rotatably supported. The cam groove drum (52) rotates around a horizontal axis (53) as shown in FIG.
54) is formed.

The cam groove (54) is located between the keeper side (54a) and the exit side (54c) of the cam roller (50a).
) is formed, and when the cam drum (52) rotates once in the direction of the arrow (55), the cam roller (50
a) reaches the exit side (50al), and the axis (53) between this
The cam grooves (5) of the drum are arranged so that the distance (P2) in the direction is equal to the pitch (P2) between the peg rows of the creel (5).
4) is formed.

Therefore, for example, when the package is replaced with the cam roller (50a) positioned on the entry side (54a) in FIG. Pitch (P2) arrow (
56) direction, that is, the creel (5) is one pinch (P
2) You will have to move by 2) minutes. At this time, the next roller (50
b) reaches the entrance side (54a), and pitch feeding of the creel is performed.

In addition, in Fig. 3, the peg rows (18a) (18f) on both sides of one creel (5) are each at a distance (P2/2) from the frame end (16a) (16b).
), and therefore, as shown in Figure 1, when creels (5a) to (5n) are aligned in the - row, the pitch between the rows of pegs is constant (P2) across all creels. All creels can be pitch-fed by intermittent rotation of the cam drum (52).

In addition, when restarting the above steps (A) and (II+), in this case, as shown in the third diagram, the peg positions in row (18b) and row (18c) are shifted up and down by half a pitch (Pi/2). Because the peg (18c) is in the up position, the height of the vertical arm (704) in the position of FIG. 12A is raised a distance (PI/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 (Ml) in FIG.

In Fig. 1, the packages (K1) to (K8) at the alignment position (A) are hung on the arm of the supply device (700), and the time required for supplying them to the creel and the empty winding of the next creel row are shown. During the operation time for removing the take-up tube, the empty trays (tl) to (t8) at the alignment position (B) are released in the direction of the arrow (43) by the release of the stopper (42), and the empty trays (tl) to (t8) at the alignment position (B) are released in the direction of the arrow (43), and the empty trays (tl) to (t8) at the alignment position (B) are ejected in the direction of the arrow (43). At (300), new trays (TI) to (T8
) is subjected to the extraction process in the same manner as described above and is transferred to the alignment position (A), so that each of the above-mentioned devices is controlled. I will be treated.

Therefore, the next new package can already be lined up at the alignment position (A) during one cycle operation of the package exchange device for removing an empty take-up tube and supplying a new puff cage, and the next new package can be already lined up at the alignment position (A) and transferred to the exchange device (700). A large number of packages can be fed to the creel very efficiently without any waiting time.

In the above embodiment, the buff cage in the alignment station run (STI) has a constant diameter (D).
As mentioned above, as long as the packages are aligned in -rows using the trays (T1) to (T8) containing 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 lot change, or a change in process, the position of the center hole of the package on the aligned tray will always remain the same, and therefore the replacement ! Since the package support arm (700) can simply perform the same operation, the control of the exchanger is simplified.

In the above embodiment, the alignment state of the packages at the alignment position ff(A) is set to be one line, but this means that the pan cage replacement work is performed as indicated by the chain double-dashed line (44) at the creel (5) shown in the third figure.
This is related to the assumption that the process is to be performed in each row, as shown by the double-dashed lines (45) and (46). In this case, the package transport conveyor and the empty take-up tube transport conveyor on the alignment station run side should also be medium-wide conveyors suitable for arranging trays in a zigzag pattern similar to the arrangement of pegs, and furthermore, the change equipment should be (7
By replacing the arm (704) of 00) with an arm in which the mounting positions of the pan cage chunk pieces are arranged in a zigzag pattern, the package can be replaced in the same cycle as described above in each of the above cases. Ru.

In addition, when replacing the package for each stage of the creel as shown by the two-dot chain line (45) in Fig. 3,
The step of rotating the long arm (704) to the vertical position as shown in Figure C is omitted, and the 12th C1, 12D1, 13A,
The puff cage can be exchanged by repeating the operations shown in FIG. 13B.

〔Effect of the invention〕

As described above, in the present invention, the yarn supply package supplied to the warper creel can be conveyed and supplied with the yarn end drawn out in advance, and the yarn can be easily pulled out from the package during warping work.
