Description

[Detailed description of the invention] A2 Purpose of the invention [Industrial application field] The present invention is a method of automatically applying tape at a constant pitch in a spiral shape around the outer periphery of a bundled wire in which a plurality of wiring cords are bundled. Concerning a spiral taping machine for winding binding wire.

[Conventional technology]

Conventionally, a wiring harness (a bundle of wiring for automobile ignition, lights, charging, auxiliary equipment drive, etc.)

) are factory-produced as assembled units with dimensional standards determined in advance for each vehicle type. To manufacture such a harness, the wiring cords are positioned and bundled according to the distance of each device to be wired, and tape is wrapped around the outer circumference at a constant pitch (
This was done by spiral taping).

By the way, the spiral taping of such a harness is
Most of the work was done manually.

This is because wiring harnesses installed inside automobile dash boards or engine compartments are shaped like branches with varying thicknesses in order to minimize the wiring distance, and each tip has A connector or the like is connected in advance to the . This is because there has not yet been a versatile automatic spiral taping machine that can accommodate harnesses of these various standards.

[Problem to be Solved by the Invention] However, manual spiral taping is very labor intensive as it must be done while maintaining a certain tension on the tape and paying attention to a certain pitch (overlap margin). At the same time, it was a task that required skill. Therefore, a large part of the automobile production process is
Nowadays, as unmanned and automated processes are progressing through robots, there is a call for automation and improved production efficiency in the manufacturing of wiring harnesses, and the inefficiency of spiral taping has become a problem.

Therefore, the present invention was developed focusing on the inefficiency of manual taping, and its purpose is to easily and quickly perform spiral taping using a drive motor without requiring force. The present invention provides a wire binding spiral taping machine that is capable of accommodating wiring harnesses of various standards.

1) and the notch (14) of the rotating body (12) preferably have a central angle of 30° to 180''.

〔Example〕

Next, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 is a perspective view showing the entire embodiment, FIG. 2 is a front view thereof, FIG. 3 is a side view thereof, and FIG. 4 is a bottom view thereof. In the following description, the direction of arrow a shown in the drawings will be referred to as the front, and the opposite direction will be referred to as the rear.

■ is the base. The base l has a grip portion 2a in a substantially T-shape.
, 2b, 2c are arranged. That is, one gripping part 2a in the front-rear direction and two gripping parts 2b and 2C in the front left-right direction are attached with a slight downward inclination. A gear case 3 is arranged with its surface vertically behind the gripping parts 2b and 2c, and a mounting table 5 for a drive motor 4 is provided horizontally behind the rear surface thereof. The mounting table 5 is
They are connected and held at the end 6 of one gripping part 2a.

Also, i! A substantially ring-shaped guide ring 9 is vertically fixed to the end portion 7 of the three gear cases of the mounting table via an angle 8. The lower part of the guide ring 9 has a central angle 9
A notch 11 is formed by cutting out a part of the ring by 0°. The central angle of the notch is set to approximately 90° in this embodiment, but may be set to approximately 30''' if desired.
It may be set to ~180°; if it is less than 30'', it will be difficult to insert or remove the binding wire 34, which will be described later, into the notch 14, and if it is more than 180°, the rotating body 12 will not rotate smoothly. Further, a flange 10 is formed on the entire rear side of the guide ring 9.

Reference numeral 12 denotes a rotating body, which fits around the flange lO so as to wrap around the guide ring 9 from the inner diameter side, and is held slidably along the inner circumferential surface 13 of the guide ring 9.

A notch 14 is also formed in the rotating body 12 so as to approximately coincide with the notch 11 of the guide ring 9, and gear teeth 1 are provided on the front periphery of the zero rotating body 12, which has a so-called horseshoe shape.
5 is engraved. The gear 15 meshes with transmission gears 16a and 16b that are pivotally supported on the left and right sides in the gear case 3, and the transmission gear 16 is connected to an intervening gear 17a and an intervening gear 17a, respectively.
Drive gear 1 coupled to drive motor 4 via 17b
It is connected to 8. Although the tooth profile of each gear is not shown in FIG. 5, it may have a normal shape, and the number of teeth can be set as appropriate.

Next, a positioning plate 19 cut out in an abbreviated shape is attached to the front of the rotating body 12 via a holding rod 20.20. This attachment is performed by fastening and clamping the wing nuts 22 of the holding loft 20 at appropriate positions of two slits 21.21 formed in the positioning plate 19.

The direction of the slit 21 is such that the corner 23 of the slit 21 can move in the radial direction from the center of the rotating body 12.

Reference numeral 24 denotes a substantially angular tape holder that is fixedly attached in the radial direction from the front of the rotating body 12. The tape holder 24 has a bottle 2 at its tip 25.
The rocking plate 26 is pivotally supported by the shaft 7. The swing plate 26 includes a tape support roller 28 and a guide roller 2 arranged at an appropriate distance from the tape support roller 28 on the rotation center side.
9 is attached. Note that the support roller 28 and the guide roller 29 are arranged so as to be located in front of the positioning plate 19. A tape reel 31 into which a tape wheel 30 is press-fitted is attached to the support roller 28 and fixed with a screw 32.

Reference numeral 33 denotes protection plates fixedly attached to the left and right sides of the notch front surface of the rotating body 12. The protection plate 33 is for preventing the binding wire 34 from coming into contact with the inner circumferential surface 35 of the rotating body 12 and the inner circumferential surface 13 of the guide ring 9.

Further, a protection plate 36 is attached to the front surface of the gear case 3 in a substantially arch shape along the outer periphery of the rotation locus of the tape reel 31. This is the gripping parts 2b and 2c.
This prevents the rotating tape reel 31 from hitting the hand holding the tape reel 31.

Furthermore, 37 is a switch box for turning the drive motor 4 ON/OFF and adjusting the rotation speed.

Note that the circuit configuration inside this switch box 37 uses an existing and publicly known circuit configuration, so its details will be omitted.

Next, the operation and usage of this embodiment will be explained.

When the drive motor 4 is driven by turning on the switch, the drive gear connected to it rotates (in this embodiment, it rotates to the left as indicated by the arrow), and the intervening gear 17a meshed with it rotates.
, 17b rotate clockwise as shown by arrow C, and the transmission gears 16a and 16b meshed therewith rotate counterclockwise as shown by arrow d. Then, the rotational force is transmitted to the rotating body 12 by the transmission gear 16 through -15 of the rotating body 12 that meshes with the transmission gear 16 . Therefore, since the positioning plate 19, tape holder 24, and tape reel 30 are integrally attached to the rotating body 12,
They will rotate to the right (arrow e) together with the rotating body 12, that is, they will perform a turning movement around the rotation axis of the rotating body 12.

When using this machine, first, the tape reel 31 on which the tape 38 is wound is passed through the tape wheel 30 and screwed onto the screw 3.
Attach it to the support roller 28 in step 2.

Next, the notch 11 of the guide ring 9 and the notch 14 of the rotating body 12 are aligned while being held by either the front left or right gripping portions 2b, 2C of the base l and the front-back gripping portion 2a. Then, the binding wire 34 is positioned at the center of the rotating body 12.

At this time, the positioning plate 19 is
is adjusted with the wing nut 22 and slid so that the binding wire 34 comes to the center of the rotating body 12.

Next, the tape 38 is let out from the tape reel 31, hooked onto the guide roller 29, and then wrapped around the binding wire 34. From this state, while driving the drive motor 4 to rotate the rotating body 12 and keeping it horizontal with the grip part 2, it is moved backward (in the opposite direction of the arrow a) on the fixed moving IC binding 34.

As a result, the tape 38 is sequentially attached to the binding wire 3 at a constant pitch.
The outer circumference of 4 will be wrapped in a spiral technique. Note that the tape 38 is attached to the swing plate 26 which is pivotally supported by the bin 27, and is slightly inclined, so that a constant pitch can be maintained.

[Effects of the Invention] Since the present invention is configured as described above, it achieves the effects listed below.

(1) Since the tape is rotated by a drive motor and wrapped around the binding wire, spiral taping can be performed with less force and several times faster than conventional manual methods. In addition, the tension can also be kept constant during winding.

(2) Since the binding wire is taken in and out from the notch of the rotating body and the guide ring, the binding wire can be wound from any desired position, and it can also be stopped midway.

(3) Since the tape is held swingably by the rocking plate, by setting the tape reel inclination appropriately,
Tape pitches (overlapping allowances) can be set according to each standard.

(4) Since the positioning plate and the protection plate are arranged, twisting of the binding wire can be prevented.

(5) Since the tape is guided by the guide roller, the tape is always fed out to the center of the binding wire, and winding can be done neatly.

(6) Since the gripping portions are arranged in three T-shaped locations on the base, the taping machine can be moved in any direction, resulting in good workability.

(7) A protective plate is installed to protect the worker's hands from the rotating tape.
