Description

  The present invention relates to a tape cutter, and in particular, is suitably used as a tape cutter for woven fabric tapes that are widely used as a wire harness tape.

  Conventionally, an adhesive tape has been widely used for bundling electric wires of a vehicle wiring harness, and the adhesive tape is often broken by an operator after winding. On the other hand, recently, woven tape has been widely used for reasons such as good wear resistance, an effect of preventing abnormal noise, and good appearance. The woven tape is made by impregnating a rubber-based adhesive with a base material made of a resin yarn having a rigidity such as PET, so that the operator cannot manually cut the base material resin yarn. It is cut using a tape cutting tool.

  Tape winding is used in various processes in the wire harness assembly process. For example, in order to bind the main wire and branch wire group of the wire harness, to fix the corrugated tube terminal sheathed to the wire harness to the wire harness, to attach the clip to the wire group, to the joint connector on the outer periphery of the wire group The tape is wound around a number of places, for example, to fix the film. Therefore, there are a number of positions where the tape is cut after the end of winding of the tape, and in the case of a woven fabric tape in which the tape is not broken by hand, a hand-type tape cutting tool carried by an operator is used.

  Conventionally, a tape cutting tool shown in FIGS. 6A and 6B has been widely used as the hand-type tape cutting tool. The tape cutting tool 100 is provided with a cutting blade holding portion 102 that protrudes from a part of an annular gripping portion 101 held by a worker's hand and is refracted in the circumferential direction after being protruded in the outer diameter direction, and the inner surface of the cutting blade holding portion 102 And a tape cutting space 103 between the outer periphery of the annular gripping portion 101. The upper part of the cutting blade 105 is fixed to the cutting blade holding part 102 by molding, the lower part of the cutting blade 105 is protruded from above into the tape cutting space 103, and the tape 200 inserted into the tape cutting space 103 is pulled upward to cut. The blade 105 can be cut. Further, a tape insertion arm portion 106 is provided by bending from the circumferential tip of the cutting blade holding portion 102 toward the annular gripping portion 101 in the inner diameter direction, and an inner surface of the tip of the tape insertion arm portion 106 and the annular gripping portion 101 are provided. A tape insertion port 110 is provided between the outer peripheral surfaces of the tape cutting space 103 and is continuous with the tape cutting space 103. The tape 200 is inserted horizontally from the tape insertion port 110 and inserted into the tape cutting space 103.

  In the tape cutting tool 100, after winding the wire harness of the wire harness with the tape 200, the tape 200 is horizontally placed in the tape insertion port 110 of the tape cutting tool 100, moved to the tape cutting space 103, and then the tape 200 faces upward. It can be cut by simply pulling on.

Conventionally, as a tape cutting tool, Japanese Patent Application Laid-Open No. 2008-238345 has provided a cutting tool with high safety in which a cutting blade does not touch a finger. However, since the cutting tool is not a hand type but is installed at a fixed position, the tape cutting position after the tape winding operation is dispersed at various positions. As inappropriate.
Further, as a hand-type tape cutter, in Japanese Patent Application Laid-Open No. 11-49418, the coil of the adhesive tape 400 shown in FIGS. 7A and 7B is accommodated, and the drawn adhesive tape 400 can be cut by the cutter 401. Tape cutters are provided. However, since the adhesive tape to be wound around the wire harness is long, the workability becomes very poor if the adhesive tape is wound around the wire harness while being accommodated in the tape cutter and pulled out. It is.

JP 2008-238345 A Japanese Patent Laid-Open No. 11-49418

  The tape cutting tool 100 for hand-type wire harnesses shown in FIG. 6 has a tape insertion slot 110 that is thinned, but an unexpected force acts to cause the tape or small-diameter wire to be inserted into the tape insertion slot 110. There is a possibility that the cutting blade 105 will be pushed and cut by the cutting blade 105. Moreover, since the cutting blade 105 protrudes into the relatively wide tape cutting space 103 and is exposed, there is a risk that an operator may inadvertently put his finger and be injured. Furthermore, since the cutting blade 105 cannot be replaced and is disposable, if the sharpness deteriorates, it must be discarded and resources are wasted.

  The present invention solves the above-mentioned problem, prevents a tape or a small-diameter electric wire from being inadvertently inserted from the tape insertion port, prevents the cutting blade from being constantly exposed to the tape cutting space, and allows the cutting blade to be replaced. It is an object of the present invention to provide a tape cutting tool that can be easily formed.

In order to solve the above problems, the present invention provides a tape cutting space that gradually narrows in the lateral direction from the tape insertion opening provided at one end of the main body toward the connecting portion on the other side. A cutting blade that is inserted into and fixed to the insertion groove in the vertical and vertical directions provided in the connecting portion on the back end side is projected,
Provided is a tape cutting tool configured to cut from one end to the other end in the width direction of the tape by pulling a tape to be horizontally placed in the tape cutting space toward the cutting blade arranged in the longitudinal direction. ing.

The vertical dimension on the back end side of the tape cutting space from which the cutting blade protrudes is not less than the thickness of the tape to be cut and not more than 2 mm.
That is, the cutting blade protrudes to the back end side of the tape cutting space, but the vertical dimension on the back end side allows the tape to be inserted, but the operator's finger does not enter and a thin wire is also inserted. As an unacceptable dimension, it is designed not to be cut inadvertently for safety.

  An insertion port at the tip of the insertion groove is provided on the outer end surface of the connecting portion, and a gripping portion in which a gripping bar protrudes from the outer surface of the cover portion that opens and closes the insertion port is integrated with or separate from the main body. It is preferable to provide it.

The cutting blade can be easily inserted and removed through the insertion port. In particular, if a recess is provided through which the operator can insert the cutting blade with a finger, the cutting blade can be replaced more easily and reliably.
Furthermore, it is possible to prevent the cutting blade from inadvertently falling off and coming off by closing the insertion port with a cover portion that also serves as a gripping portion.
Note that the cover of the insertion port and the grip portion may be provided at different positions.

  Further, one end of a string is connected to the main body or the gripping part, the other end of the string is connected to a spring, and a storage container storing the spring is arranged around the wire harness assembly work table, and a tape. It is preferable to have a configuration in which the string can be pulled and moved to the cutting position.

  With the above configuration, it is not necessary for the operator to carry the tape cutting tool, and the tape cutting tool is suspended from above when the tape winding work is completed and the tape is cut on the wire harness assembly work table. The string can be pulled down and moved to the cutting position. In addition, after the tape cutting operation is completed, it can be automatically returned to its original position by a spring, and the usability is greatly improved.

  As described above, the tape cutting tool of the present invention inserts the tape laterally from one end in the width direction into the tape cutting space, pulls it toward the cutting blades arranged orthogonally in the vertical direction, and pulls the tape in one end in the width direction. It cut | disconnects so that it may cut with a cutting blade toward the other end. By adopting the cutting method, a cutting blade may be arranged on the back end side of the tape cutting space having a thickness capable of inserting the tape, and the vertical dimension on the back end side of the tape cutting space from which the cutting blade protrudes can be set. Usually, it can be made equal to the thickness of a tape of 1 mm or less. As a result, an operator's finger, a thin electric wire, etc. cannot inadvertently enter the back end side protruding the cutting blade of the tape cutting space, and safety can be improved. Therefore, it is not necessary to use a control lever or the like to project the cutting blade into the tape cutting space at the time of cutting the tape and retract at the time of non-cutting, and the configuration of the tape cutting tool can be simplified.

(A) and (B) are drawings showing other conventional examples.

Hereinafter, embodiments of the tape cutting tool of the present invention will be described with reference to FIGS. 1 to 5.
As shown in FIGS. 1 and 2, the tape cutting tool 1 is provided with a groove 5 that is cut laterally from the left end side of a substantially rectangular parallelepiped body 20 of a resin molded product to reach the right connecting portion 4. The right side of the upper and lower symmetrical upper and lower parts 3 in the figure is connected by a connecting part 4.
The groove 5 is provided on the opposing surfaces 2a and 3a of the upper portion 2 and the lower portion 3 from the other end side in the length direction X toward the connecting portion 4 on the one end side, and the groove 5 gradually converges on the tip of the V-shaped portion 5a. A back end side 5b having a thin and constant dimension from the back to the back end is provided, and a space formed by the groove 5 is defined as a tape cutting space 6.

The wide end of the V-shaped portion 5a of the tape cutting space 6 is defined as a tape insertion opening 7, and a thin rectangular cutting blade 10 is fixed vertically in the vertical direction in the figure at the back end of the converged back end 5b. ing. The vertical height dimension H on the back end side of the tape cutting space 6 from which the cutting blade 10 protrudes is set to 2 mm or less, which is slightly thicker than the thickness of the woven fabric tape 50 to be cut.
The woven fabric tape 50 is cut from the tape insertion opening 7 toward the cutting blade 10 so that the woven fabric tape 50 is torn by the longitudinally arranged cutting blade 10 by pulling the woven fabric tape 50 from one end in the width direction. I am going to do it.

  In order to fix the cutting blade 10 to the main body 20, the insertion groove 8 is cut in the connecting portion 4 in the vertical direction from the vertical center portion of the end surface 4 a of the connecting portion 4. The insertion groove 8 has a rectangular shape, and as shown in FIG. 2B, the vertical length 8x of the insertion groove 8 corresponds to the length 10x of the cutting blade 10, and the cutting depth 8y of the insertion groove 8 Corresponds to the width 10 y of the cutting blade 10. The thickness of the insertion groove 8 is a thin slit corresponding to the thickness of the cutting blade 10. The central portion of the insertion groove 8 in the vertical length direction opens at the back end 6p of the tape cutting space 6, and the opposing surfaces 2a of the upper part 2 and the lower part 3 sandwiching the tape cutting space 6 continuous with the back end 6p, An insertion groove 8 is opened on the back end side of 3a.

  Further, as shown in FIGS. 3A, 3 </ b> B, and 3 </ b> C, an arcuate recess 9 is provided across an insertion port 8 a that is opened in the end surface 4 a of the connecting portion 4. The arcuate recess 9 facilitates replacement of the cutting blade 10 by inserting an operator's finger into the arcuate recess 9 when the cutting blade 10 is inserted into and removed from the insertion groove 8.

  As shown in FIGS. 1 and 2, the cutting blade 10 inserted into the insertion groove 8 has a cutting edge 10a protruding from the back end 6P of the tape cutting space 6 and inserted into the tape cutting space 6 as described above. The cloth tape 50 can be cut. On the other hand, the end face of the base 10 b of the cutting blade 10 is located at the insertion port 8 a of the insertion groove 8. Since the cutting blade 10 inserted into the insertion groove 8 is in a substantially tight fit state, it does not fall off from the insertion port 8a, but the gripping portion 15 is thinly attached to one end of the end surface 4a while covering the insertion port 8a. The hinge part 16 is provided so that it can be opened and closed.

  The grip portion 15 connects one end of the cover portion 15a having substantially the same width as the end surface 4a of the connecting portion 4 to the thin hinge portion 16, and is provided with a locking claw 15r at the other end, and the other end side of the end surface 4a of the connecting portion. Is inserted and locked in a locking frame 4r provided in the frame. Further, the gripping bar 15b protrudes from the outer surface of the cover portion 15a so that the operator can move the tape cutting tool 1 to the tape cutting position with the gripping bar 15b.

  As shown in FIG. 4, a string 18 is inserted into a hole 15 h provided in the gripping bar 15 b, and the other end of the string 18 is connected to a tip of a spiral spring 22 accommodated in a storage container 21. The spiral spring 22 biases the string 18 in a direction to pull it back to the storage container 21 side. As shown in FIG. 4B, the storage container 21 is installed on an instruction stand 31 erected along the wire harness assembly work table 30, and the tape cutting tool 1 is above the wire harness assembly work table 30 with a string 18. Hanging on. When the operator pulls down the tape cutting tool 1 while holding the gripping rod 15b at the time of cutting the tape, the string 18 is pulled out from the storage container 21 and placed at a required position on the wire harness assembly work table 30. The bottom surface of the lower part 3 is fixed so that the woven fabric tape 50 can be cut at an arbitrary position. In addition, in the fixed state, the withdrawal of the string 18 can be temporarily stopped, and thereafter, the tape cutting tool 1 can be automatically returned to the upper position without interfering with the work by being pulled back by the spiral spring 22 by the operation of returning the string 18. I am doing so.

  Instead of hanging the tape cutting tool 1 on the wire harness assembly work table as described above, the tape cutting tool 1 is mounted on a jig mounting table arranged in the vicinity of the wire harness assembly work table and prepared. Occasionally, an operator may take it out of the jig platform and place it on the wire harness assembly work table for use.

  As shown in FIGS. 5 (A) and 5 (B), the tape cutting operation by the tape cutting tool 1 is performed in the width direction as indicated by the arrow from the wide tape insertion opening 7 to the tape cutting space 6. It is inserted horizontally from one end and pulled toward the far end where the cutting blade 10 protrudes. Thereby, as shown in FIG.5 (C), the woven fabric tape 50 is cut | disconnected so that it may tear with the cutting blade 10 toward the other end from the one end of the width direction. Finally, as shown in FIG. 5 (D), the woven fabric tape 50 is completely cut off at the connecting portion 4 side of the tape cutter 1.

  To replace the cutting blade 10, simply open the gripping portion 15, remove the cutting blade 10 from the insertion port 8 a of the insertion groove 8, insert a new cutting blade 10, and then close the gripping portion 15 and lock it. It's okay. In this way, the cutting blade 10 can be easily replaced.

  The tape cutting tool 1 has a cutting blade 10 protruding on the back end side of the tape cutting space 6. The back end side portion from which the cutting blade 10 protrudes has a vertical height H slightly smaller than the thickness of the tape. Since it is about 2 mm just by making it wide, an operator cannot put a finger carelessly and safety is high. In addition, the thin electric wire is not pushed in, and the electric wire is not cut unexpectedly.

  The present invention is not limited to the above-described embodiment, and a grip portion in which the cover portion and the grip rod are integrated may be provided separately from the main body so as to be freely attachable. Further, the cover portion and the grip portion may not be provided integrally, and the grip portion may protrude from another part of the main body.

  Furthermore, although the tape cutting tool of the present invention is suitably used for cutting woven fabric tapes that are not broken by hand, which is widely used for wire harnesses, it can also be used as a tape cutting tool for other tapes and other applications. Preferably used.
