Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for wrapping tape around a cable. Various devices have been developed for twisting wires together to make cables and wrapping tape around them, but the cables must be replaced every time the tape part is finished, reducing the operating rate of the twisting machine, and furthermore, the tape part itself is Due to their large size, replacement work is extremely difficult. Increasing the amount of tape pat wrapped will lengthen the time until the tape runs out, but the pat will become larger and the rotational speed will be lower, and if the diameter of the pat is made smaller to increase speed, the duration will be shorter and the need for frequent replacement will be required. Usually, it is necessary to do this every 5 to 6 minutes, and no matter how much the efficiency of the twisting machine itself is improved, it is still limited by taping.

This invention is an attempt to solve this drawback.In a tape winding device, two tape storage reels are installed opposite each other, the tape is pulled out from one reel and wound around a cable, and the tape on one reel is finished. Then, the tape is immediately pulled out from the other reel and wrapped around the cable, and the tape is alternately wrapped around the cable on the two storage reels, while the previous empty reel is reeled with tape supplied from the outside. The present invention provides a tape winding device that can perform the drawer for winding the tape and the winding of the tape supplied from the outside, and can perform the work efficiently without interrupting the tape winding. be.

To explain the figures, FIG. 1 is a schematic illustration of the device of the present invention, FIG. 2 is a detailed structure of the part inside the dotted line A in FIG. 1, and FIG. FIG. 3 is a side sectional view showing the configuration of a portion inside the dotted line B. FIG.

In the figure, 1 is the cable to be wrapped with tape, which is twisted together by a twisting machine (not shown) on the left side of the figure, fed into the device from the left side of the figure, and is twisted into a hollow cable. Enter inside the tape guide holder drive shaft 2. Two toothed electromagnetic clutches 48 and 49 are mounted on this tape guide holder drive shaft 2.
is fixed. Thus, the tape guide holder drive shaft 2 is driven by the motor 5 via a gear 6 coaxial with the motor 5 and a gear 7 fixed to the tape guide holder drive shaft that meshes with the gear 6.

In the apparatus of the present invention, tape storage reels 8 and 9 are provided facing each other on the left and right, and flyers 10 and 11 are provided along the tape storage reels 8 and 9, respectively.
Therefore, the flyers 10 and 11 have their drive shafts 10
a and 11a are loosely fitted onto the tape guide holder drive shaft 2 via a bearing 61 so as to be able to move relative to each other. Further, the drive shafts 8a, 9a of the tape storage reels 8, 9 are connected to the flyer 1 through bearings 62, respectively.
It is loosely fitted onto the drive shafts 10a and 11a of Nos. 0 and 11 so that they can move relative to each other. Therefore, a part of the drive shafts 8a and 9a of the tape storage reel is connected to the pulleys 20 and 2.
It is formed as 4. A belt 21 is stretched between the pulley 20 and a pulley 20' coaxial with the motor 22, and the tape storage reel 8 is driven by the motor 22. Similarly, the tape storage reel 9 is driven by a pulley 24, a pulley 24', a belt 25, and a motor 26.

In addition, as mentioned above, the tape guide holder drive shaft 2
Tooth-shaped electromagnetic clutches 48 and 49 are fixed on the drive shaft 2 (hereinafter simply referred to as the drive shaft 2).
The flyers 10 and 11 can be rotated together with the drive shaft 2.

The fryer 10 has guide rolls 12, 1 on the side.
4 is attached, and a belt 51 is wound between them. Further, a guide roll 27 is attached above. Guide rolls 13, 15 and a belt 52 are similarly attached to the sides of the fryer 11, and a guide roll 28 is attached above. The guide roll 14 is movable by an electromagnet 29 and a rod 30 attached to the fryer 10, and the guide roll 15 is movable by an electromagnet 31 and a rod 32 attached to the fryer 11, so that the interval therebetween can be adjusted. The belts 51 and 52 serve to guide the tape, as will be described later.

Central guide roll 1 is placed below the rolls 14 and 15.
6 and 17 are provided, and the distance between both rolls can be adjusted by an electromagnet 18 and a rod 19.

A pulley 41 for supplying the tape below the tape storage reel 8, a supply stand 42, a brake 43 for giving the tape the required tension.
is provided. A similar device is provided below the tape storage reel 9 and is generally indicated by the reference numeral 44.

A tape guide holder 47 having a guide roll 45 and a tape winding angle adjustment roll 46 is attached to the drive shaft 2 at the right end of the device. The entire device is supported by frames 33 and 34 at both left and right ends. As shown in FIG. 3, the shaft 47' of the tape guide holder 47 is supported on the frame 34 by a bearing 63. In the figure 1a
shows the cable 1 wrapped with tape 40. Note that 50 is a slip ring that guides electricity to the electromagnetic clutch.

Next, to explain the operation, assume that the tape 40 currently wound on the tape storage reel 9 is wound onto the cable 1, and a new tape is being wound on the tape storage reel 8 from the supply stand 42. . The reel 9 is rotated by the motor 26, the electromagnetic clutch 49 is energized, the drive shaft 2 and the drive shaft 11a of the flyer 11 are integrated, and the flyer 11 rotates together with the drive shaft 2. Then, the tape 40 is taken out from the reel 9 via the guide roll 28, and the tape 40 is taken out from the reel 9 through the guide roll 28.
3. The cable passes through the belt 52 and the guide rolls, passes between the center guide rolls 16 and 17, enters the hollow part of the hollow drive shaft 2, and travels inside the hollow part above the cable 1. (See FIG. 2), the cable 1 is wound around the cable 1 via a guide roll 45 and a winding angle adjustment roll 46. This is because although the tape guide holder 47 rotates together with the drive shaft 2, the cable 1 does not rotate and moves to the right, so that winding is possible.

Meanwhile, the tape storage reel 8 on the opposite side is driven by a motor 22 using pulleys 20, 20' and a belt 21, and is driven by a supply stand 42.
From there, a new tape 40' is fed out via the pulley 41 with appropriate tension by the brake 43, and wound onto the tape storage reel.
During this time, the flyer 10 is stationary with the electromagnetic clutch 48 disconnected. Note that the winding speed of the new tape on the reel 8 is made faster than the speed at which the new tape is taken out from the reel 9.

When the tape has been removed from the reel 9, the end of the new tape is pulled out from the reel 8, and the guide rolls 14, 15 and 16, 17 are brought into contact with each other by the action of the electromagnet.
The end of the tape from reel 9 and the start of a new tape from reel 8 are pressed together. Since each end of the tape is coated with adhesive, both tapes are connected and the tape from the reel 8 is now wound around the cable 1. A new tape is similarly wound onto the reel 9, the electromagnetic clutch 49 is disconnected, and the flyer 11 remains stationary. To ensure continuous tape connection, the drive shaft 2 and the drive shafts 10a, 11a of the flyers 10, 11 are connected by toothed electromagnetic clutches 48, 49 so that the relative positions of the shafts are constant.

The device of this invention has the above configuration,
With a relatively simple configuration, the tape can be wound around the cable without interruption, making it possible to manufacture cables with high efficiency.
