JPS59133170A - Method and apparatus for preventing external damage of wire material on taking-up said wire material - Google Patents

Abstract

PURPOSE:To prevent a wire material from being damaged by a taking-up drum, by operating a press-fitting roller by detecting the approach of the wire material to the taking-up drum and permitting automatic covering for the wire material with cushion material, when the wire material is taken-up onto the taking-up drum. CONSTITUTION:When a wire material 1 is taken-up onto a taking-up drum 3, a detector 4 detects the passage of the wire material 1, and a press-fitting roller 5 is attached under pressure onto the lower edge surface of the wire material by said signal. Then, a cushion material 6 such as Kraft paper set in still state onto the press-fitting roller 5 is attached under pressure onto the wire material 1 by the press-fitting roller 5, and sent with the wire material 1 to the taking-up drum 3. In this case, the cushion material 6 is rounded by a correcting device 8 and used for coating the wire material 1. Thus, the wire material 1 is prevented from being damaged by the collar part of the taking-up drum 3. Thus, the cushion material can be automatically supplied, and the working performance can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and a device for preventing damage that is likely to be caused to the filament at the flange of the drum when the filament is wound onto a winding drum.

When the filament is wound onto a winding drum, the filament is likely to be damaged by the flange of the drum. That is, whereas the drum is made of a hard and hard-to-deform material7, the striatum is generally made of soft and flexible material, so it is difficult to wrap the striatum. When removing the drum, damage is likely to occur, and this tendency is particularly noticeable at the flange of the drum.

Particularly in the case of high-voltage cables, even slight scratches or the like on the conductor pose a serious problem because its characteristics deteriorate.

Therefore, in order to prevent damage to the filament, a method is generally used in which a shoe/con material is inserted into the flange of the winding drum when the filament is wound. However, since such a conventional method is carried out manually, there is an inconvenience in that the operator must constantly monitor the winding state.

The present invention does not require such inconvenient work, and provides a method for dynamically supplying cushioning material to the flange of a winding drum to prevent trauma from occurring at the flange during winding of a filament. and equipment.

In other words, the present invention detects when the filament is wound onto the drum and approaches the drum flange, and operates the pressure roll based on this detection signal to remove the filament from the drum. The shoe/con material present between the strip and the pressure roll is pressed against the strip, and the strip is continuously coated with the kunonyon material. As the body moves, it is sent to the winding drum,
Trauma prevention force θ of the filament when winding the filament, which is characterized by detecting that the filament being wound is moving away from the drum flange and cutting the cushioning material based on this signal.
, is.

The invention further relates to a device for carrying out such a trauma prevention method. That is, the apparatus of the present invention includes a detection means for detecting when the filament approaches the drum flange and when it moves away from the drum flange when the filament is taken up by the winding drum. a crimping roll that operates to press against the filament body in response to a signal detected when approaching the filament, a crimping material supplying means for supplying lace material between the filament body and the crimping roll, and a crimping roll. cushioning material correcting means for covering the striated body with the shoe/con material pressed against the striated body; and when the detection means detects that the striated body moves away from the drum flange, the cushioning material correcting means covers the striated body by a signal. This device is a device for preventing damage to the filament during winding of the filament, which includes a cutting means for cutting the shoe material.

Note that in the above device, the same detection device is used to detect when the filament approaches or moves away from the drum flange, but separate detection devices may also be used.

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a schematic diagram showing an example of an apparatus for implementing the present invention. That is, in a system for winding the filament 1 onto the winding drum 3 through the traverser guide roll 2, this device detects when the filament 1 being wound once approaches the drum flange or moves away from the drum flange. Detector 4, detector 4 detects the striatum 1
A cushion supply roll 7 that supplies the shoe/con material 6 to the winding system of the crimping roll 51, which operates to press against the filament body in response to a signal when it detects that the shoe approaches the collar, and the filament body 1 and A cushioning material corrector 8 that covers the striated body tK with the shoe 7 supplied by the pressed crimping roll, and the detector 4 detect that the striated body 1 is moving away from the trim flange. FIG. 1 is an enlarged side view showing an example of a straightener 8 used in the above-mentioned device.
It has a conical shape, and the tape-like cushioning material can be rolled up and cut on the outer periphery of the filament.

FIG. 3 is a front view showing an example of the cushion material cutting machine 9 used in the above-mentioned device, which has a recess 10 with a diameter approximately equal to or slightly smaller than the diameter of the straightener 8. It consists of 1 pair of parts, and by closing them, the protruding part of the part is fixed by pressure iRL between both members, and the crimping part removes the shoe/cone covering the filament by one winding force. and cut.

Fig. 1 shows a state in which the crimping roll 5 is in pressure contact with the filamentous body and the cushioning material 6 is being sent to the winding drum 3 while being covered with the filamentous body. The roll 5 is located at a position slightly apart from the filament 1, and the cushioning material 6 is placed on it.

In this state, the filament 1 is being wound up on the winding drum 3. When the filament 1 approaches the drum flange, the detector 4 detects this and The pressure roll 5 is brought into pressure contact with the lower end surface of the filament 1 by the signal. A cushioning material 6 such as kraft paper, which is placed stationary on the pressure roll 5, is pressed against the filament 1 by the pressure roll 5, and is sent out toward the winding drum 3 together with the filament 1. In this case, since the cushioning material corrector 8 is provided, the cushioning material is rolled up and covers the filamentous body 1, so that the filamentous body 1 is rolled at the flange of the drum while being covered with the cushioning material. This prevents the filament from being damaged by the drum flange.

When the filament moves away from the drum flange, it is detected by the detector 4, and this signal closes the cutting machine 9, cutting the cushioning material at this position, and moves the pressure roll 5 away from the filament 1. It will be returned.

By repeating such operations, the cushioning material at the drum flange can be automatically supplied at all times, and the conventional work of monitoring the winding work can be completely omitted, which is a practical value of the present invention. is a dog.
