The control device 41 stores the one end portion on the downstream side in the transport direction of the wire protection tube 15 that is the cutting position as a base point.
The control device 41 operates the transport device 37 again. One end of the wire protection tube 15 is inserted into the core body 110 of the core 109 before the molding device 45. The projecting piece 111 is simultaneously inserted into the slit 35 of the wire protection tube 15.

  If the control device 41 determines that the molding position (position of a desired length from the base point) of the wire protection tube 15 has reached the molding die 87 based on the length information measured by the length measuring device 39, the conveyance is performed. The apparatus 37 is temporarily stopped, and a molding start / end signal 69 is output to the molding apparatus 45. The molding device 45 starts molding. At this time, the outer peripheral surface of the core 109 and the inner peripheral surface of the concave portion 33 of the wire protection tube 15 come into contact with each other.

  In the case of manual operation, for example, the link mechanism 93 is actuated by moving the operation handle 97 of the mold clamping device 91 forward by using a lamp or the like lit by a molding start end signal 69 as a cue, and the lifting plate 81 is lowered. . At this time, the upper mold 83 and the lower mold 85 are moved closer to the vertical position by the link mechanism 93 and the interlocking member 95 and then clamped in the final operation. At this time, the outer peripheral surface of the convex portion 31 of the wire protection tube 15 abuts against the inner peripheral surface of the protection tube cavity 99 and the locking tool cavity 101 of the molding die 87, and the arc-shaped protrusion 105 of the protection tube cavity 99 is formed. The outer peripheral surface of the concave portion 33 of the electric wire protection tube 15 is in contact with the inner peripheral surface of the concave portion 33 of the electric wire protection tube 15 and the outer peripheral surface of the core 109. For this reason, the convex portion 31 and the concave portion 33 of the electric wire protection tube 15 are prevented from being deformed by the pressure of the molten resin injected into the locking tool cavity 101, and the molten resin enters the protective tube cavity 99. It is prevented.

  Next, the molten resin is injected from the injection device into the molding die 87, and the locking tool cavity 101 is filled with the molten resin. That is, the locking tool 13 is integrally formed at a predetermined position (molding position) of the wire protection tube 15 that has been transported by a predetermined transport amount (molding process). At this time, the molten resin is set to a temperature at which the wire protection tube 15 is not plastically deformed.

  When the resin filled in the locking tool cavity 101 is cured after a predetermined resin curing time, the operation handle 97 of the mold clamping device 91 is lifted upward, and the upper mold 83 is moved upward to form a molding die. 87 is opened (see FIG. 1). In the molding apparatus 45, when the upper die 83 is raised, the upper die 83 and the lower die 85 are shifted in the horizontal direction, and a work space 117 (see FIG. 1) for taking out the product is secured above the lower die 85. Is done.

  Next, the molding device 45 operates the transport device 37 again. When the control device 41 determines that the distance between the locking tool 13 and the cutting device 43 has reached a desired length (a desired length from the base point measured by the length measuring device 39), the control device 41 stops the conveying device 37, The electric wire protection tube 15 is cut by operating the cutting device 43 (cutting step). Thereby, the electric wire protection tube 15 is cut | disconnected from the locking tool 13 in the desired position of the conveyance direction upstream. As a result, a locking tool-equipped wire protection member 17 having a desired overall length, in which the locking tool 13 is integrally formed on the outer peripheral surface of the wire protection tube 15, is formed.

  And the manufacture of the electric wire protection member 17 with a locking tool is completed by extracting the electric wire protection member 17 with a locking tool from the core 109. Thereafter, the above-described manufacturing method is repeated to continuously manufacture the wire protector 17 with a locking tool.

Next, the effect | action of the manufacturing apparatus 11 and the manufacturing method of the electric wire protection member 17 with a locking tool which has the said structure is demonstrated.
In the manufacturing apparatus 11 and the manufacturing method of the wire protection member 17 with a locking tool according to the present embodiment, a length measuring device 39 (length measuring process) and a cutting device 43 are arranged along the conveyance path of the linear wire protective tube 15. The (cutting step) and the molding device 45 (molding step) are arranged in an arbitrary order. In addition, in this structure, the conveying apparatus 37 shall convey the electric wire protection tube 15 in the arbitrary positions of a conveyance path | route along a longitudinal direction.
The transport amount of the wire protection tube 15 transported by the transport device 37 is measured by the length measuring device 39. The length information measured by the length measuring device 39 is input to the control device 41. The control device 41 outputs a transport start / stop signal 65 of the wire protection tube 15 to the transport device 37 based on the input length information.

  Specifically, the length measuring device 39 can detect an arbitrary position of the electric wire protection tube 15 passing as a base point. The relative distances between the length measuring device 39, the cutting device 43, and the molding device 45 installed in the conveyance path are stored in the internal storage device 59 of the control device 41 as a known length. Accordingly, if a certain point of the wire protection tube 15 that has passed through the length measuring device 39 is a base point, the control device 41 corresponds to the position of the wire protection tube 15 corresponding to the cutting device 43 from the base point and the forming device 45. The position of the electric wire protection tube 15 to be determined can be determined. In other words, the control device 41 can transport the wire protection tube 15 by controlling the transport device 37 so that the position of a desired length from the base point reaches the cutting device 43 and the molding device 45.

  If said base point is a cutting position, the electric wire protection tube 15 will be cut | disconnected by a base point, and this cutting position will become an end part of the conveyance direction downstream side of the electric wire protection tube 15. FIG. Thereby, the electric wire protection member 17 with a locking tool in which the locking tool 13 is formed at a position of a desired length from one end of the electric wire protection tube 15 can be manufactured. Of course, the wire protection tube 15 is cut at a desired position upstream of the conveying direction from the position where the locking device 13 is formed, so that the desired portion from the locking device 13 to the other end of the wire protection tube 15 is obtained. It becomes possible to manufacture the wire protection member 17 with a locking tool having a length.

  As a result, it is possible to manufacture the wire protection member 17 with a locking tool in which the locking tool 13 is formed at an arbitrary distance from both ends (that is, the desired total length).

  In addition, while continuously transporting a single long wire protection tube 15, one end and the other end of the wire protection tube 15 are cut at predetermined positions so that both ends can be connected to a desired position. It is possible to continuously manufacture the wire protection member 17 with a locking tool in which the stopper 13 is formed.

  Moreover, in the manufacturing apparatus 11 and the manufacturing method of the wire protection member 17 with a locking tool according to the present embodiment, the wire protection tube 15 includes a length measuring device 39 (length measuring step), a cutting device 43 (cutting step), and a forming device. It is desirable that the wire protection member 17 with a locking tool is manufactured in the order of 45 (molding step).

  According to the manufacturing device 11 and the manufacturing method of the wire protection member 17 with a locking tool according to the present embodiment, the length measuring device 39 uses the cutting position that is one end portion on the downstream side in the transport direction of the wire protection tube 15 or the cutting position. A predetermined position is detected as a base point (length measuring step). When the molding position of the wire protection tube 15 (position of a desired length from the base point) reaches the molding die 87 based on the length information measured by the length measuring device 39, the control device 41 moves the conveying device 37. After stopping once, the shaping | molding apparatus 45 is operated and the locking tool 13 starts integral molding to the electric wire protection tube 15 (molding process). Further, the control device 41 temporarily stops the conveying device 37 when the position of a desired length from the base point in the wire protection tube 15 in which the locking tool 13 is integrally formed reaches the cutting device 43, and then the cutting device 43. Is operated to cut the wire protection tube 15 (cutting step). And the electric wire protection member 17 with a locking tool which was cut | disconnected by the cutting device 43 and became the desired full length is taken out from the shaping | molding apparatus 45. FIG.

  In this configuration, the wire protection tube 15 in which the locking tool 13 is not molded can be passed through the general cutting device 43, and there is no need to prepare a dedicated cutting device. Further, no unnecessary cutting portion is generated in the wire protection tube 15. That is, when the cutting device 43 is located downstream of the molding device 45, if the length of the one end portion and the locking tool 13 is shorter than the distance between the cutting device 43 and the molding device 45, the occurrence of a residual cutting portion can be avoided. Absent. On the other hand, according to the configuration of the present embodiment in which the cutting device 43 (cutting step) is arranged upstream of the forming device 45 (molding step), there is no occurrence of a residual cutting portion.

Next, the manufacturing apparatus 121 and the manufacturing method of the electric wire protection member 17 with a locking tool according to another embodiment of the present invention will be described.

In the manufacturing apparatus 121 and the manufacturing method of the wire protection member 17 with a locking tool according to the other embodiment, the length measuring device 39 uses the cutting position that is one end portion on the downstream side in the transport direction of the wire protection tube 15 or the cutting position. A predetermined position is detected as a base point (length measuring step). When the position of a desired length from the base point reaches the forming device 45, the control device 41 temporarily stops the conveying device 37 and then operates the forming device 45 to integrate the locking tool 13 with the wire protection tube 15. Molding (molding process). In the case of manual operation, the forming operation is performed by the operation handle 97. Then, when the conveyance is resumed and the position of a desired length from the base point in the wire protection tube 15 integrally formed with the locking tool 13 reaches the cutting device 43, the control device 41 temporarily stops the conveyance device 37. Thereafter, the cutting device 43 is operated to cut the wire protection tube 15 (cutting step).

According to the manufacturing apparatus 121 and the manufacturing method of the electric wire protection member 17 with the locking tool, the other end portion of the electric wire protection tube 15 is cut by the cutting device 43 installed at the most downstream side in the transport direction, so that the electric wire protection with the locking tool is performed. Until the manufacture of the member 17 is completed, the electric wire protection tube 15 is continuous from the length measuring device 39. Thereby, the attachment position of the latching tool 13 and the full length of the wire protection member 17 with a latching tool can be manufactured with high accuracy. Further, the electric wire protection member 17 with a locking tool that has been cut by the cutting device 43 to a desired total length is put into a finished product charging box 119 or the like provided on the downstream side of the cutting device 43. Therefore, the trouble of taking out the wire protection member 17 with a locking tool from the molding device 45 can be saved.
The fixed guide portion 71A of the cutting device 43 has a guide insertion hole 72 larger than the fixed guide portion 71 so as to guide and support the electric wire protection tube 15 in which the locking tool 13 is integrally formed.

Next, the manufacturing apparatus 123 and the manufacturing method of the electric wire protection member 17 with a locking tool which concern on other embodiment of this invention are demonstrated.

In the manufacturing apparatus 121 and the manufacturing method of the wire protection member 17 with a locking tool according to the other embodiment, an arbitrary position that passes is detected as a base point by the length measuring device 39 installed on the most downstream side in the transport direction ( Measuring process). When the position of the wire protection tube 15 upstream of the desired length from this base point reaches the forming device 45, the control device 41 once stops the conveying device 37 and then operates the forming device 45 to engage the locking tool 13. Is formed into a wire protection tube 15 (forming step). In the case of manual operation, the forming operation is performed by the operation handle 97. When the conveyance is resumed and the position that is a predetermined length upstream in the conveyance direction from the molding position of the locking tool 13 reaches the cutting device 43, the control device 41 temporarily stops the conveyance device 37, and then the cutting device 43 is operated and the electric wire protection tube 15 is cut | disconnected (cutting process). This cutting position is the other end of the wire protection tube 15 on the upstream side in the transport direction.

According to the manufacturing device 123 and the manufacturing method of the wire protection member 17 with the locking tool, since the locking tool 13 is first formed on the supplied linear wire protection tube 15, for example, the length measuring device 39 is clamped.
