Abstract

PURPOSE:To make it easy to set timings for the start of binding work and the stop of feeding of a following belt clamp by a method wherein from a moment when a preceding belt clamp has been fed in a winding section of an automatic binding device, a feeding gear is retreated from a passage, and feeding of a following belt clamp is stopped. CONSTITUTION:Belt clamps 70, which are linked by a plurality, are fed to a winding section, and at this winding section, the outer periphery of an object to be bound such as wire harness, etc., is bound by a preceding belt clamp 70. A feeding gear 30, which is provided in a passage, by which the belt clamp 70 is guided to the winding section, to be able to advance or retreat, can be rotated by a designated operating source. Also, by rotating the feeding gear 30 under a condition where the feeding gear 30 is advanced in the passage, the belt clamp 70, which is located in the passage, can be fed in the winding section. When the preceding belt clamp 70 has been fed in the winding section, a gear retreating mechanism makes the feeding gear 30 retreat from the passage in a linked motion. Also, while a binding work is performed by the preceding belt clamp at the winding section, the feeding gear 30 is retained under a retreated condition from the passage by a retaining mechanism.

Description

[Detailed Description of the Invention] [Industrial Application Field] The invention is surprising in that a plurality of belt clamps connected in a direction are supplied to a winding section, and in this winding section, a wire harness is connected by the preceding belt clamp. This invention relates to a belt feeding mechanism of a belt clamp automatic binding device for binding the outer periphery of objects to be bound such as.

[Prior Art] An example of a belt feeding mechanism described in '+V+' is Belt Clamp Automatic Binding 5, which has already been filed by the present applicant.
Patent application No. 63-322907 for being able to list Al
(See @Mei II and drawings).

This automatic binding device is configured such that a plurality of belt clamps tied in the longitudinal direction (3I) are automatically supplied to the winding section one by one for every - number of binding operations. Then, at this winding part, the belt part of the belt clamp is wound around the outer periphery of the wire harness, etc., the belt part is tightened and bound, and after the binding, the connecting part of the belt clamp is cut off. is all done automatically.

In the automatic binding device, when the preceding belt clamp is inserted into the passage leading to the winding section, the roller protruding from a part of the bottom of the passage is pushed down, and in conjunction with this movement, the bell!・The gear for feeding the clamp (rotationally driven) moves into the passage so as to protrude from a part of the bottom surface. As the gear rotates in this state, the preceding belt clamp is sent through the passage toward the winding section.

When the preceding belt clamp reaches the winding portion and the binding operation by this belt clamp is started, the buckle portion of the following belt clamp is located at the location of the roller. Since this buckle part does not contact the roller and is located in the space of the passage, the force pushing down the roller is released, and the roller receives the force of the return spring, etc.
It moves in the upward direction. In conjunction with this, the gear A7 moves backward from the passage, and the feeding of the bell 1-clamp is thereby stopped.

[Problem to be Solved by the Invention 1] In the automatic bundling Ai having the above configuration, the feeding of the subsequent belt clamp is stopped when the buckle portion of the subsequent belt clamp reaches the position of the roller in the passage. For example, if the quality of the belt clamp is changed, the timing between the start of the bundling work by the belt clamp preceding C in the winding section and the stop of the feeding of the subsequent belt clamp may deviate. . To deal with this, it is necessary to prepare several types of automatic binding devices in which the arrangement of the rollers differs depending on the type (length) of the belt clamp.

The present invention aims to solve such problems.

[Means for Solving the Problems] In order to solve the above problems, the belt feeding mm of the belt clamp automatic binding device in the present invention is configured as follows.

That is, the belt clamp automatic binding device supplies a plurality of belt clamps connected in the longitudinal direction to a winding part, and in this winding part, the preceding belt clamp binds the outer periphery of the object to be bundled, such as a wire harness. The structure is such that the work is completed once. This belt clamp automatic binding device includes a passage for guiding the belt clamp toward the winding section. The feed gear, which is capable of entering into or retracting from the passage, is rotatable in response to torque transmission from a predetermined drive unit (such as a motor). Further, by rotating the feed gear while entering the passage, it is possible to feed the belt clamp located within the passage to the winding portion.

When the preceding belt clamp is fed into the winding section, the gear retracting mechanism is interlocked with this and causes the feeding gear to move backward from within the passage. Further, during the binding operation using the preceding belt clamp at the winding portion, the feeding gear is held in a retracted state from the inside of the passage by a holding mechanism.

[Function 1 In the above configuration, a plurality of bells 1 connected in the longitudinal direction
- When the clamp is inserted into the passage of the automatic binding device, the rotation of the feeding gear causes the belt clamp to be sent toward the winding section 1. When the clamp is fed, the gear retraction mechanism causes the feed 1'A) to be retracted from within the passage. At the same time, the feeding gear is held in a retracted state from inside the passage by the holding mechanism during the previous binding operation using the belt clamp at the winding section. Therefore, from the time when the preceding belt clamp is fed into the winding section to the time when the binding operation is completed, feeding of the subsequent belt clamp by the head feeding gear A7 is stopped.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

Next, the feeding gear 173o is inserted into the guide groove 24 in the passage 22.
The gear reversing mechanism 40 for performing a reversing operation from a state in which the vehicle has entered will be explained. First, the actuating lever 42 is rotatably attached to the housing 10 at one end (lower end in the drawing) by a fulcrum shaft 44 . The engagement hole 46 formed in a part of the operating lever 42 has a
A pin 36 fixed to the tip (free rotation end) of the arm portion 35 of the gear retainer 34 is engaged.

Also, at the other end of the operating lever 42 (the upper end in the drawing), a part of the interlocking link 50 is rotated by a connecting pin 52! JJ is freely coupled to the upper end of the operating lever 42 and a protrusion 21 formed on the outer wall surface of the inner case 20.
A return spring 48 is provided between the two.

This return spring 48 has a force of 3+1! that moves the actuating lever 42 around the fulcrum shaft 44 in a counterclockwise direction (J direction) in FIG.

One end of an arm 64 is fixed to this shaft 62, and the other end of this arm 64 is rotatably connected to the end of the interlocking link 50 (the right end in FIG. 1) by a connecting pin 66. has been done.

FIG. 3 shows a part of the interlocking link 50 in an enlarged perspective view. As is clear from FIG. 3, a holding block 54 is attached to a part of the interlocking link 50 so that it can be rotated slightly by the pin 56 (=t l-J).

An electromagnet 57 is supported by the housing 100fl by a retainer 58 at a location facing the holding block 54 at a certain distance to the right in FIG. When the electromagnet 57 is energized and the interlocking link 50 moves, the holding block 1 cock 5

As a result, the feed gear 30 disengages from the locking teeth (not shown) of the belt portion 72Δ of the subsequent belt clamp 70A.

't, when the preceding belt clamp 70 is fed into the winding part 14 of the automatic binding device, the following belt clamp 7
Feeding of 0△ is stopped.

When the interlocking link 50 moves to a state not shown in FIG. 4, its holding block 54 touches the electromagnet 57 (a). This electromagnet 57 is energized when the operation switch of the automatic binding device is in the on state. Since the holding block 1 cock 54 is maintained in this state, the holding block 1 cock 54 is attracted and held 1) by the rIi magnet 57. Therefore, even if the preceding belt clamp 70 moves further from the state shown in FIG. The reverse machine side 40 is maintained in the state shown in FIG.

As a result, the locking portion 88 is disengaged from the hook 80, and the feed gear 30 and gear retraction mechanism 40 return to their original states as in the first embodiment.

Third Embodiment Gear retraction mechanism 40 and holding mechanism 5 of Embodiment 1.2
3, an electromagnet (not shown) that is energized when the holding piece 60S is rotated to the state shown in FIG. 4 is used to suck and hold the gear retainer 34 of the feeding gear 30 in the state shown in FIG. 4. It's good. Similarly to the first embodiment, the electromagnet in this case is also de-energized when the automatic bundling device is turned off upon completion of the bundling work. When the current is turned off, the force of the spring (not shown) acting on the gear retainer 34 causes the feed to move to 1! The gear 30 is entered into the iQσ guide groove 24.

[Effects of the Invention 1] The present invention is such that when the preceding belt 1-clamp is fed into the winding part of the automatic binding device, the feeding gear is retracted from the passage from the point in time when the preceding belt 1-clamp is fed into the winding section of the automatic binding device, and The feeding of the following belt clamp is stopped at the time when the bundling work is completed.Therefore, it is easy to set the timing for starting the bundling work by the preceding belt clamp and stopping the feeding of the subsequent belt clamp. Even when the types of clamps are different, it can be handled satisfactorily.
