Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a manufacturing process of electric wires and cables (hereinafter, referred to as a cable), in particular, a length of a cable passing through a manufacturing apparatus (hereinafter, "dynamic length of cable"). Said) relates to the winding machine for the tape length indicator tape used in the long process.

[Conventional technology]

The dynamic length of the cable in the process of manufacturing the cable is generally long. Particularly, in the cross-linking step, the insulating coating is cross-linked and cooled while passing through the cross-linking pipe and the cooling pipe, so that the moving length of the cable becomes long. In addition, when changing the supply and take-up drums in cable manufacturing, the production machine can be operated continuously without stopping, immediately after being taken out from the supply drum or at take-up. An accumulator is provided immediately before being wound on the drum, and the running cable is temporarily wound while the drum is being replaced to adjust the slack, so that the moving length of the cable becomes longer.

The measurement of the length of a cable manufactured in such a cable manufacturing process and its display are performed according to the conditions of the manufacturing process, but the common point is that the running cable vibrates when running. Due to the fact that it is carried out in a place where the running speed does not change, there is a considerable distance from the place where the strip length is measured to the take-up position, and it is necessary to display the strip length measurement result by some means and convey it to the take-up position. come.

As a method of displaying the strip length, when a strip length measuring instrument (hereinafter referred to as a measuring instrument) measures a predetermined strip length, at the same time, manually wrap the adhesive tape around the surface of the running cable, and at the take-up position. There is a known method of replacing the drum of the above and managing the length of the strip in the subsequent process.

However, when such a strip length display is manually performed, there is a problem that the display position is slightly shifted due to the timing of wrapping the adhesive tape being shifted due to an alarm generated from the measuring instrument. Further, if the operator misses the alarm, there is a problem that the worker passes through without displaying the length of the article.

Therefore, as described in JP-A-52-123263, "Stripe length measuring method that also uses a visible display tag," a display signal (adhesive tape) is automatically attached to the striatum in response to a measurement signal from a measuring instrument. A method of wrapping around is proposed. According to this method, the timing of wrapping the adhesive tape is shifted or the operator does not hear the alarm and wrap the adhesive tape like the method of manually attaching the adhesive tape by the alarm issued from the scale as described above. The problems that occur are eliminated.

By the way, the "instantaneous adhesive means" for winding the adhesive tape disclosed in JP-A-52-123263 includes: a, an air shooter for guiding compressed air, b, a flexible member such as a foamed resin and a sponge. It is composed of a folding mechanism that uses the above as the roller body, and a side pressing mechanism for making the c and the display tag stick more firmly. The roller body is bent and adhered to the peripheral surface of the filament body, and the roller body descends from above and fits the filament body from the notch provided in the lower portion to the hole provided in the center thereof. It does that. Therefore, when the roller main body is operated while the linear body is in the traveling state, the roller main body does not rotate in accordance with the traveling of the linear body, so that friction occurs between the linear body and the linear body. Therefore, when the contact portion between the linear member and the roller body is a soft material such as an insulator or a sheath of the cable, problems such as scratches occur.

[Problems to be solved by the device]

The present invention has been made in view of the above problems of the conventional technology, and its purpose is to automatically attach an adhesive tape to the surface of a running cable when a measuring instrument measures a predetermined length. In addition, it is an object of the present invention to provide a device that attaches safely and reliably at low cost even if the center axis level of the traveling cable changes.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a tape length winding tape winding machine around a traveling cable according to claim 1, wherein an adhesive tape feeding means for feeding and cutting the adhesive tape to a desired length, and an adhesive tape fed from the feeding means are conveyed and pasted. An air nozzle that flutters to the suction cup side of the attachment means, a suction cup that adsorbs the adhesive tape that has been cut out, and a transport arm that inverts the suction cup and waits the adhesive surface of the adhesive tape toward the running cable side. Adhesive tape transporting and pasting means consisting of a sticking link for receiving the measurement signal from the scale and stopping the suction of the adhesive tape and at the same time pasting the adhesive tape on the upper surface of the running cable, and on the downstream side of the transport and pasting means. An adhesive tape wrapping means provided, wherein the adhesive tape wrapping means, a pressing roller that rotates by a semicircular groove in contact with the adhesive tape sticking surface of the traveling cable, The rotating shaft is rotatably supported so as to be inclined so that the upstream side is high and the downstream side is low with respect to the axis of the traveling cable, and the pair of brush rollers that rotate by contacting both side surfaces of the traveling cable, A pair of winding rollers, which rotate in contact with semicircular grooves on both sides, are sequentially provided from the upstream side to the downstream side in the traveling direction, and the adhesive tape conveying / adhering means measures the outer diameter of the traveling cable. The structure is provided with an elevating and lowering drive means for elevating and lowering the transfer arm based on the standard size signal from the container and adjusting the height of the suction cup during standby to an appropriate position.

[Action]

In the machine for winding a strip length indicating tape around a running cable of the present invention configured as described above, the adhesive tape fed out from the adhesive tape feeding means is cut into a required length on the suction plate of the adhesive tape feeding and pasting means. At that time, the air blown out from the air nozzle prevents the adhesive tape from warping and makes the adhesive tape flow toward the suction plate. The suction board continues to suck the adhesive tape, is reversed by the transport arm, receives the measurement signal from the measuring instrument, ends the suction, and sticks the adhesive tape on the upper surface of the traveling cable.

In the adhesive tape winding means, the pressing roller presses the adhesive tape on the upper surface of the traveling cable when the semicircular groove comes into contact with the adhesive tape adhering surface of the traveling cable and rotates. Next, the brush roller contacts the peripheral surface of the traveling cable and rotates. Since the brush roller is rotatably supported so as to be inclined so that the upstream side is high and the downstream side is low with respect to the axis of the running cable, the brush roller rotates as the cable runs, and its rotation is an adhesive tape. And the adhesive tape is pressed against both side surfaces of the running cable. Furthermore, since the semi-circular groove of the winding roller contacts and rotates so as to cover the traveling cable from both sides, the remaining part of the adhesive tape not yet pressed onto the cable is also pressed onto the lower half of the traveling cable. Thus, the adhesive tape is wrapped around the entire circumference of the cable.

Further, since the brush roller is provided so that the rotating shaft is inclined with respect to the traveling cable shaft, the contact range of the traveling cable is widened, and the level of the traveling cable shaft moves up and down according to the change in the cable outer diameter. However, regardless of that, it will come into good contact with the running cable.

Further, the transfer arm of the adhesive tape transfer means is operated based on the standard dimension setting signal from the outer diameter measuring device of the traveling cable, and the drive elevating means elevates and lowers the conveying arm according to the change of the outer diameter of the traveling cable, and during standby. Adjust the suction cup height.

Then, the micro screw 55 is rotated by the differential motor 54, and the rotation angle is read by the rotary encoder 56 and input to the comparator 57. The comparator 57 outputs the standard dimension setting signal f until the set value is reached. When this standard dimension setting signal f is input to the differential motor 50 of the adhesive tape transporting / adhering means 2 and is rotated in the same manner, the adhesive tape transporting / adhering means 2 is moved by the amount corresponding to the change in the dimension of the traveling cable 19. By moving up and down, the distance L with the traveling cable 19 is properly maintained. In this case, the differential motor 50 and the micro screw 51 have the same specifications as those of the outer diameter measuring instrument 52. If the specifications are changed, a converter may be inserted between the comparator 57 and the differential motor 50.

FIG. 10 is a side view showing details of the pressure roller of the adhesive tape. As shown in FIG. 10, the adhesive tape adhered to the upper surface of the cable 19 running on the guide roller 40a is a pressing roller 40 having a semicircular groove attached to a swing arm 41 operated by a standard length measuring signal. Then, the cable 19 is attached to the upper peripheral surface of the cable 19, which is the adhesive tape attachment surface.
(See FIG. 13 (a)).

FIG. 11 is a side view showing details of the brush roller. 11th
As shown in the figure, the pair of brush rollers 42, which are inclined with respect to the axis of the traveling cable 19, connect the traveling cable 19 to each other.
Swings toward both side surfaces of the cable, contacts the both side surfaces of the cable, clamps the cable, and rotates as the cable travels. The brush roller 42 is rotatably supported so that the rotation axis is inclined so that the upstream side is high and the downstream side is low with respect to the axis of the traveling cable, so that the rotation acts to stroke down the adhesive tape, Attach the adhesive tape to both sides of the running cable (see Fig. 13 (b)). Moreover, the brush roller 42
Since the rotating shaft is installed so as to be inclined with respect to the traveling cable shaft, the range of contact with the traveling cable is widened, the traveling cable sways slightly, or the level of the traveling cable shaft is Even if it moves up and down according to the change of, it will come into good contact with the running cable regardless of it.

The degree of contact of the brush roller 42 with the cable 19 is adjusted symmetrically in the longitudinal direction by moving and adjusting the sector gear 45 that is slidably fixed to the arm 43 by the circular elongated hole 44. The amount of movement is adjusted by the adjustable stopper 46. The brush material of the brush roller 42 has a hardness and an appropriate degree of bending that do not damage the cable 19,

When the adhesive tape adhered as described above approaches the front of the take-up drum, an alarm is issued by means not shown, and the worker at the take-up position starts preparatory work such as drum replacement.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

With the basic structure of the adhesive tape feeding means, the adhesive tape conveying and pasting means, and the adhesive tape wrapping means, when the measuring instrument measures the predetermined strip length, the adhesive tape can be automatically attached to the cable surface. There is no fear that the timing of wrapping the adhesive tape will shift and the display position will shift slightly, or that the tape will pass without displaying the strip length.

Then, when the adhesive tape is fed and separated from the head, air blown out from the air nozzle prevents the adhesive tape from reversing and flows toward the suction cup, so that the adhesive tape can be reliably fed to the suction disc.

In the adhesive tape winding means, the pressing roller presses the adhesive tape on the upper surface of the traveling cable by rotating the semicircular groove in contact with the upper surface of the traveling cable on which the adhesive tape is adhered. Next, the brush roller rotates as the traveling cable travels, and the rotation acts so as to stroke down the adhesive tape to press the adhesive tape onto both side surfaces of the traveling cable. Furthermore, since the semi-circular groove contacts and rotates the winding roller so as to cover the traveling cable from both sides, the remaining part of the adhesive tape which is not yet pressed onto the cable is also pressed onto the lower half of the traveling cable. Since the adhesive tape is wrapped around the entire circumference of the cable in this manner, there is no fear that the adhesive tape will come off.

Further, since the brush roller is provided so that the rotating shaft is inclined with respect to the traveling cable shaft, any portion of the brush roller supports the cable even if the traveling cable shaft slightly swings or moves. The adhesive tape can be wrapped around the cable safely and securely.

Further, since the reversible arm of the adhesive transporting and pasting means that can be raised and lowered is moved up and down by the driving means that operates based on the standard size setting signal of the outer diameter side sizing device of the traveling cable,
Even if the travel cable size is changed, the distance between the adhesive tape transporting and affixing means and the travel cable is automatically made appropriate in cooperation with the standard size setting of the outer diameter measuring instrument, and the labor can be saved.
