DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band clip mounting device for winding a band clip around a wire harness or the like and tightening and fixing the band clip.

[0002]

BACKGROUND OF THE INVENTION Plastic tying members having a band and a band receiving head are known and have been used for many years to tie individual wires together to form wire harnesses and the like. These tying members are sometimes also used, for example, to secure wire harnesses to structural parts of the vehicle body. However, in recent years, for example, a binding member that can be easily inserted and engaged with a clip or a clip head that can be inserted into a hole or a recess appropriately formed in a part of a vehicle body, for example, has been required. Such binding members are particularly called band clips, and are classified into two types.

In one type of band clip, the direction in which the band is clipped and the direction in which the band receiving portion receives the band portion are substantially orthogonal, and such a band clip is described in US Pat. No. 5,601,261. I have. In this band clip, the clip portion is arranged at right angles to the band receiving portion. European Patent Publication No. 0 39043
4. This type of band clip may be wound and tightened using the apparatus described in U.S. Pat. No. 4,793,385.

Another type of band clip is described in US Pat. No. 5,584,452. As shown in FIGS. 1 and 2 of the present application, the band clip includes a band portion 4 and a clip head 2 having a band receiving portion 3 for receiving a tip portion 6 of the band portion 4. This type of band clip has a clip direction,
Is different from the above-described type of band clip in that the direction of insertion into the appropriate opening or concave portion is substantially parallel to the band receiving direction of the band receiving portion 3. In particular, as shown in FIG. 2, the band portion 4 is substantially aligned with the clip head 2.

[0005]

As a matter of fact, the above-mentioned band clip is manually wound around a wire harness and then manually tightened. Therefore, it is necessary to provide a device for winding and tightening a band clip, at least semi-automatically, around a wire harness or the like, in particular, a band clip in which the clip direction shown in FIGS. 1 and 2 is substantially parallel to the band receiving direction of the band receiving portion. Have been.

[0006] It is an object of the present invention to enable at least partial automation, thus making band clips more regular.
An object of the present invention is to provide a device for attaching a band clip to a wire harness, which enables efficient use.

[0007]

According to the invention, the above object is achieved by a device having the features of claim 1.
In particular, the device of the present invention comprises a base member having clip holding means for holding the clip portion of the band clip.
The clip retaining means is preferably arranged such that the clip portion of the band clip is inserted in a substantially similar manner as the clip portion of the band clip is later inserted into an opening formed in that portion of the vehicle body to secure the wire harness to a portion of the vehicle body, for example. Is formed to accommodate the For this reason, it is preferable that the clip portion of the band clip be pushed into the clip holding means in the clip direction and held by the clip holding means.

The band clip further has a receiving portion or an opening for receiving the band end, and the band receiving direction and the clip direction are substantially parallel. Further, the device of the present invention is provided with a band end turning member which is movable with respect to the base member, turns the band tip around the wire harness by shortening the distance from the base member, and passes the band end through the band receiving portion. In particular, the band end turning member is directed toward the band receiving portion of the band clip while turning the band tip. Preferably, the band is folded back by sliding the tip of the band with the band end folding member.

[0009] The device of the present invention also includes a band clamp member movable relative to the base member. In particular, the band fastening member is provided on the opposite side of the band end folding member with respect to the base member or the clip holding means, and is movable independently of the band end folding member. The band fastening member clamps the band end passing through the clip receiving means of the base member, that is, the base member, and pulls the band while increasing the distance from the base means to fasten the band to the wire harness.

[0010] Preferably, the band end turning member has a band guide groove extending particularly in a curved shape. In particular, by providing a band guide groove having substantially the same width as the band portion of the band clip on the band end folding member, the band tip is guided and folded more accurately toward the band receiving portion. The band guide groove extends in a curved shape, in particular in an elliptical or substantially semicircular shape, and is received thereby to turn or to make a U-turn of the guided band. As a result, the band tip is returned to the band receiving portion adjacent to the end of the band portion on the clip portion side. Most preferably, the tip of the band end fold member is formed to bend or incline continuously with the other portions so that the band is folded over about 180 ° or more. How much the folding angle is greater than 180 ° depends on the distance between the band end folding member and the base member and the length of the band portion of the band clip.

Although the band fastening member is described herein as part of the apparatus of the present invention, the band fastening member itself has an independent inventive concept. The band tightening member opens by contacting the base member, and separates from the base member to clamp the band end portion passing through the band receiving portion. Further, the band tightening member may perform the above-described operation by abutting on, for example, a plate member having an opening, a ring, or the like provided between the band fastening member and the base member, instead of directly abutting on the base member. . Anyway, the band fastening member having such a feature is used for automatically clamping the band tip and the band,
And automatic tightening.

Whether forming part of the device of the present invention or forming an independent device, the band tightening device is preferably spring biased, and more preferably a base member or clip holding means or the like. The self-adjustment of the clamping force is made in proportion to the pulling force acting to increase the distance from the other means having the through hole.

[0013] Preferably, the band fastening member comprises two grip pawls mounted so as to have a scissor-like structure, and the axis of rotation of the grip pawl is guided along an elongated hole, particularly along the elongated hole. It is urged by a spring. Accordingly, the grip claws of the band fastening member are separated from each other when pressed against the surface. When the band tightening member is moved or pulled, the grip pawl automatically grips the band, in particular, the band tip located therebetween, due to the combination of the scissors-like structure and the biasing force of the biasing means.

The device of the present invention may further include a band guide member for guiding a band or a band portion between the band end turning member and the base member. The band guide member is movable with respect to the base member, particularly rotatable, between an operating position for guiding the band portion and a retracted position retracted so as not to interfere with the movement of the band end folding member. The band guide member can be moved and positioned to further guide and hold the band tip when the folded band tip reaches the band receiving portion or while moving from the band end folding member to the band receiving portion. Preferably it is possible. Therefore, it is possible to prevent incorrect guidance of the band tip portion and incorrect insertion into the band receiving portion. However,
As described above, before the band clip is fastened to the wire harness, the band guide member must be retracted from the movement path of the band.

Preferably, the band guide member is particularly inclined or curved, and has a band guide plate which can be located between the band base and the band receiving portion, which is a portion of the band portion adjacent to the clip portion. The thickness of the band guide plate should approximately correspond to the distance between the band base and the band receiver. By providing an inclined or curved band guide plate, the band tip can be turned 180 degrees by a band end turning member.
° It is possible to accurately direct the band receiving part without turning over. For this reason, the band tip reaches the band receiver from a direction substantially parallel to the length direction of the band base. In order to improve the guiding ability, the band guide member may have an abutment provided vertically and / or parallel to the band guide plate.

To further increase the possibility of automation, the device according to the invention may be provided with cutting means for cutting off the excess band portion through the band receiver. The cutting means preferably has a cutting blade movable with respect to the base member. Preferably, the cutting blade is pivotally mounted on the base member, in particular via a bearing. Therefore, by moving the cutting blade relative to the base member, it is possible to cut off the excess band portion, particularly by the interaction between the edge of the clip holding means and the cutting blade.

The device of the present invention is preferably a drive means, in particular a fluid drive, for moving each moving member relative to the base member, ie, the band end folding member, the band tightening member, the band guide member and / or the cutting member. Means. In particular, all drive means other than for the band guide member are moved linearly, and the drive means for the band guide member are preferably rotated. However, the band guide may be additionally provided with a driving means for linearly moving the band guide so as to follow the movement of the band tip after leaving the band end turning member. With such a configuration, the movement of the band tip can be maintained and guided from the band end turning member to the band receiver. The drive axes of the drive means are preferably parallel to one another so that the movements can be easily controlled and connected in common. By arranging the drive shafts in parallel, most of the transmitted force, moment or torque can be used for driving. In any case, the provision of the driving means makes it possible to achieve a high degree of automation with high precision control and to tighten the band clip with a large force.

Finally, the device is preferably portable, and thus preferably comprises a handle mounted on the base member. In order to form the device so that it can be used in a fairly dense work environment, such as a work environment for forming a complex wire harness, it is necessary to attach the band end folded member to the base member so as to protrude. The size of the band end folding member needs to be set according to the required wire harness so that the operator can easily insert or hook the band end folding member on the portion of the wire harness around which the band clip is wound. .

Therefore, in order to ensure the most suitable and comfortable workability of the device, the handle preferably extends in a direction opposite to the projecting direction of the band end folding member. Also, the movement and operation of the device or the drive shaft is almost parallel to the handle,
Therefore, a worker using the device can easily cope with the force, thrust and moment generated during the work.
