Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a multi-twisting device, and more specifically, a method for inserting a package for twisted yarn into a pot of a multi-twisting weight and winding a tube from the pot. This invention relates to a multi-twisting device that can efficiently take out the yarn.

[Prior art]

Conventionally, as a multiple twisting device,
The publication proposes a device in which a holder provided above a multi-twisting spindle can be horizontally moved above between adjacent multi-twisting spindles.
Compared to devices in which a holder is fixed above the multi-twisting weight, this device does not allow damage to the holder when manually inserting the twisted yarn package and removing the winding tube one spindle at a time. It was possible to carry out the project smoothly without any problems.

However, recently, with the aim of improving production efficiency, it has been recommended to increase the amount of yarn wound in package cages for twisted yarn (large package), and as a result, the weight becomes too large and it is becoming difficult for workers to do the work manually. . In other words, the increased weight makes it difficult to insert the twisted yarn package into the pot accurately, and the surface of the twisted yarn package comes into contact with the holder or pot, causing the winding form to collapse and single yarn breakage. It becomes easier. In addition, such a package must be replaced with another normal twisted yarn package, and the twisted yarn package with the winding form or single yarn breakage must be used after removing the defective part. It has the disadvantage of being forced to become a ball.

On the other hand, in order to cope with the increase in weight, a transportation device such as a crane was used in the conventional device described above, but in order to operate this crane, the surface of the package for the yarn to be twisted was not brought into contact with any of the multiple holders, and the It must be inserted into the pot,
Extremely high precision is required. However, it is virtually impossible to satisfy this requirement, as the surface of the package for twisted yarn comes into contact with the holder or pot, resulting in damage to the holder, collapse of the winding form of the package for twisted yarn, and breakage of single yarns. .

[Purpose of invention]

An object of the present invention is to eliminate the drawbacks of the prior art as described above, and to provide a multi-thread twisting device that does not cause contact between the twisted yarn package and the holder even when a crane or the like is used.

[Structure of the idea]

To achieve the above object, the present invention provides a multi-twisting device in which a plurality of multi-twisting spindles arranged in rows are each provided with a holder for guiding the threads above the spindles, the proximal ends of each of the holders are connected to a common thread. The holder support part is connected to a holder support part, and the holder support part is freely movable back and forth in the direction of the rows of the plurality of multi-twisted yarn weights, and the movement of the holder support part moves each of the holders to the area above the multi-twisted yarn weights and the adjacent multi-twisted yarns. The present invention is characterized in that it is capable of reciprocating movement between the spindles and in the axial direction of the multi-twisted yarn weights at a position moved to an upper region between adjacent multi-twisted yarn weights.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

〔Example〕

As shown in FIGS. 1 and 2, in this embodiment, the multi-twisting spindles 1, 1' are provided in the two rows, and are also arranged in multiple rows along the lateral direction.
These plurality of multi-twisted spindles 1, 1' pots 2,
Packages P and P' for twisted yarns are respectively inserted into 2', and yarns Y,
Y' is drawn out while being multi-twisted and guided to a winding device (not shown) via upper guides 3, 3'. The guides 3, 3' are provided on the holder 4,
The holder 4 is connected at one end 5 to a holder support 6. This holder support part 6 extends along the horizontal direction of the spindle rows, and simultaneously connects the ends of the holders 4 provided above the adjacent multi-twisted yarn weights. The holder support 6 is held within the rail 10 and the slit 21
The holder 4 is made to protrude from the center, and in this state, the holder 4 is moved approximately horizontally from the upper region of the multi-twisted yarn weights 1, 1' to the upper region of the space 8 between the adjacent multi-twisted yarn weights, as shown by the arrow F. The moving mechanism 9 is configured to move back and forth in the direction. This moving mechanism 9 may be operated automatically using power,
Alternatively, a handle may be provided on the holder support portion 6 to allow manual operation.

The rail 10 of the moving mechanism 9 is connected to the fixed arm 1
1 to the vicinity of the upper end 13 of the rod 16 of the second moving mechanism 12.

The rod 16 is slidably fitted into a cylindrical support tube 14, and is reciprocated up and down (elevating and lowering) by supplying and discharging working fluid (generally oil) from a pipe 15 connected to the lower end of the support tube 14. I'm starting to do that. The supply and discharge of this working fluid can be controlled by a weight 17.

In the above-mentioned multiple yarn twisting device, the operation of exchanging the twisted yarn package P and the empty winding tube is performed as follows.

First, the holder 4 is moved by the first moving mechanism 9 from the upper region to the upper region between the spindles 8 along the direction of the rows of multiple twisting spindles 1 and 1', and then the second moving mechanism 12 The holder 4 is lowered in the direction of the arrow F2 (the axial direction of the multi-twisted spindle) to reach the space between the spindles 8, and is brought into the state shown in FIGS. 4 to 6. Thereafter, the yarns Y and Y' were cut between the twisted yarn packages P and P' in the pots 2 and 2' of the multi-twisting spindles 1 and 1' and the yarn introduction part 18, respectively, and the yarns were emptied. Remove the tube. Then, after inserting the new twisted yarn packages P and P' into the pots 2 and 2', the yarns Y and Y' wound around each twisted yarn package P and P' are cut. The threads Y and Y' hanging down from the thread introduction part 18 are knotted.

Next, the second moving mechanism 12 moves (raises) the holder 4 again from the spindle gap 8 in the direction opposite to the arrow F2 to reach the area above the spindle gap 8. Next, the holder 4 is moved by the first moving mechanism 9 to an upper region including the center C of the multiple twisting weights 1, 1' and stopped, and the twisting device is operated again. It is desirable to provide a holding device that locks the first moving mechanism 9 and the second moving mechanism 12 from moving during the yarn twisting operation.

7 to 10 show other embodiments of the present invention.

The first embodiment shown in FIGS. 1 to 6 is similar to the second embodiment shown in FIGS.
Whereas the first moving mechanism 9 was supported by the moving mechanism 12 of , the device of this embodiment is configured so that the second moving mechanism 12 is supported by the first moving mechanism 9. be. The first moving mechanism 9 moves a rail 15 in a direction along the direction of the row of weights of the multi-twisted weight.
are provided, and wheels 19, 19 are installed along this rail 15.
The support stand 20 is made reciprocally movable, and the support tube 1 of the second moving mechanism 12 is attached to the support stand 20.
I am trying to fix 4. On the other hand, the holder support part 6 is fixed to the upper end of the rod 16 via a fixed arm 11.

When replacing the twisted yarn package P with an empty winding tube in the above device, the first movement mechanism 9 reciprocates in the direction of the weight row and the second movement This can be performed by reciprocating movement in the direction of the weight axis by the mechanism 12.

The first moving mechanism 9 and the second moving mechanism 12 are operated independently as described above, but they may be operated simultaneously as long as these moving mechanisms do not come into contact with a stationary part such as a multi-twisted weight. You may also do so.

Furthermore, the device according to the present invention is shown in FIGS. 11 and 1.
The present invention can also be applied to a multi-twisting machine in which a large number of multi-twisting weights are installed on both sides A and B as shown in Figure 2.

Furthermore, the device according to the present invention is shown in FIGS. 13 and 1.
As shown in FIG. 4, the invention can also be applied to a horizontal multi-twisted yarn weight in which the axial directions of the multi-twisted yarn weights 1, 1' are set horizontally. In this case, the upper region of the multi-twisted spindle in the present invention should be read as the upper region in the direction in which the yarn Y is pulled out in the spindle axis direction.

[Effect of idea]

According to the multi-twisting device of the present invention, when the holder provided above or in front of the multi-twisting spindle is removed from the multi-twisting spindle and the package cage for twisted yarn is inserted into the multi-twisting spindle, Since the holder can be moved between the spindles of the multi-twisted spindle so that there is no holder in the area above the multi-twisted spindle, the above-mentioned extraction and insertion operations can be performed extremely smoothly. Furthermore, the twisting can be carried out without bringing the surface of the yarn package into contact with the holder or the pot, and without causing damage to the holder.

Therefore, it is possible to insert the twisted yarn package using an overhead crane, crane truck, lift vehicle, etc., thereby saving labor and improving the operating rate of the multiple yarn twisting device.
