The wire coating removal unit 1 according to example 1 of the present invention is used for removing the insulation coating W2 of the terminal portion W1 of the wire W and for inserting the wire W into the rubber plug C in manufacturing a wire harness used for electric wiring of an automobile.
The wire coating and removing unit 1 is a device for manufacturing a wire harness WH, and includes a wire coating and removing unit 10, a rubber plug accommodating unit 20, a rubber plug arrangement unit 40, an operation unit 50, a rubber plug temporary stock quantity acquiring unit 60, and a control unit 70.
The wire coating and removing unit 10 is generally called a wire stripping device commercially available, and has an insertion port 12 into which a terminal portion W1 is inserted into a cutter 11 of an insulating coating W2 for removing a terminal portion W1 of a wire W, and the insulating coating W2 of the terminal portion W1 inserted into the insertion port 12 is automatically removed by the cutter 11.
The rubber stopper accommodating portion 20 includes a rubber stopper attaching direction supplying portion 30, and accommodates a plurality of rubber stoppers C, the rubber stopper attaching direction supplying portion 30 supplying the rubber stoppers C to the rubber stopper arranging portion 40 in an orientation in which the electric wire W can be inserted into the insertion hole C1 of the rubber stopper C in the insertion direction of the electric wire W into the insertion port 12 of the wire coating removal portion 10.
The rubber stopper accommodating portion 20 has a cylindrical rubber stopper accommodating body 21 serving as a container for accommodating a plurality of rubber stoppers C. The rubber stopper housing body 21 has a cap 21a at an upper opening, and the cap 21a is opened to insert the rubber stopper C into the rubber stopper housing body.
The rubber plug accommodating body 21 is made of a light-transmitting resin, and the rubber plug C accommodated therein can be visually observed. Therefore, the remaining amount of the rubber stoppers C accommodated in the rubber stopper accommodating body 21 can be visually checked.
The rubber stopper additional direction supplying part 30 is provided at the lower part of the rubber stopper accommodating main body part 21, and forms the bottom surface of the rubber stopper accommodating main body part 21.
The rubber plug-attaching direction supplying part 30 includes: an additional direction movable part 31 having an additional direction guide groove part 32, the additional direction guide groove part 32 extending so as to guide the rubber stopper C toward the rubber stopper receiving mouth 41a of the rubber stopper arranging part 40; and a driving unit 33 that vibrates the additional direction movable unit 31.
As shown in fig. 4 and 5, the additional direction movable portion 31 includes a first vibration body portion 31a and a second vibration body portion 31b that vibrate in opposite directions with their surfaces approaching each other, and is vibrated by driving portions 33 and 33 provided corresponding to the first vibration body portion 31a and the second vibration body portion 31b, respectively.
The shape of the outer shape of the cross section of the additional direction guide groove portion 32, which merges the surfaces of the first vibration main body portion 31a and the second vibration main body portion 31b that are close to each other, corresponds to the outer shape of the rubber stopper C.
Further, the shape of the attaching direction guide groove portion 32 is an orientation in which the rubber stopper C is attached to be able to insert the electric wire W into the insertion hole C1 of the rubber stopper C in the insertion direction of the electric wire W into the insertion port 12.
More specifically, the shape of the sectional outer shape orthogonal to the guide direction of the rubber stopper C of the groove of the additional direction guide groove portion 32, which merges the grooves formed in the first vibration main body portion 31a and the second vibration main body portion 31b, is: the rubber stopper C is attached in an orientation capable of inserting the electric wire W into the insertion hole C1 of the rubber stopper C in the insertion direction of the electric wire W into the insertion port 12.
In the rubber stopper feeding direction supplying unit 30, the first and second oscillating main bodies 31a and 31b oscillate in opposite directions by driving the driving units 33 and 33 of the first and second oscillating main bodies 31a and 31b, respectively, so that the plurality of rubber stoppers C in the rubber stopper accommodating main body 21 move in the rubber stopper accommodating main body 21 while largely oscillating.
Therefore, the rubber stoppers C enter the additional direction guide groove portions 32 while moving due to vibration in the rubber stopper accommodating main body portion 21, and are supplied to the rubber stopper arranging portion 40 in a state where the additional direction is in the predetermined direction.
The rubber stopper disposing part 40 disposes the rubber stopper C of the electric wire W at a position facing the insertion port 12 of the wire coating and removing part 10, the position being a position where the electric wire W can be inserted into the insertion hole C1 of the rubber stopper C and inserted into the insertion port 12, that is, the wire insertion position 41b, and inserts the electric wire W into the insertion hole C1 and inserted into the insertion port 12, thereby holding the electric wire W toward the insertion port 12 by the rubber stopper C.
In example 1, the rubber stopper disposing part 40 receives the rubber stopper C whose direction is imparted by the rubber stopper imparting direction supplying part 30 and is disposed so as to move to the electric wire inserting position 41 b.
The rubber stopper disposing part 40 has a rubber stopper temporarily housing part 41 which houses a plurality of rubber stoppers C added in a direction in a moving section of the rubber stopper C from a rubber stopper receiving mouth 41a which receives the rubber stopper C added in the direction by the rubber stopper adding direction supplying part 30 to an electric wire inserting position 41 b.
The rubber plug temporary housing portion 41 is made of a light-transmitting resin material, and houses a plurality of rubber plugs C in a row along the extending direction in a state where the rubber plugs are added in one direction by the rubber plug adding direction supplying portion 30, with the rubber plug receiving nozzle 41a as one end and the wire inserting position 41b as the other end extending obliquely downward so that the rubber plugs C can move from the rubber plug receiving nozzle 41a to the wire inserting position 41b by their own weight.
In the rubber stopper temporary housing part 41, the plurality of rubber stoppers C, which are biased by the rubber stopper biasing direction supplying part 30, move to the electric wire insertion position 41b by their own weight.
Further, a free opening/closing door 42 is provided at an electric wire insertion position 41b of the rubber plug temporary housing portion 41. The openable/closable door 42 is a door that is opened in the right and left directions, and in a closed state using elastic force, the rubber stopper C is held at the electric wire insertion position 41b in a state where the insertion hole C1 is exposed.
When the electric wire W inserted through the rubber stopper C is taken out from the insertion port 12, the openable and closable door 42 is opened against the elastic force acting in the direction in which the rubber stopper C is closed by being hit from the inside of the openable and closable door 42.
The operation unit 50 is implemented by a foot switch, and performs an operation of starting the insulation coating removal process by the electric wire coating removal unit 10.
More specifically, the operating unit 50 outputs a signal indicating that the insulation coating removal process is started to the control unit 70 when the operator depresses the foot switch.
In embodiment 1, the operation unit 50 is implemented by a foot switch, but is not limited to a foot switch, and other operation means such as a manual switch may be used.
The rubber stopper temporary stock quantity acquiring unit 60 is implemented by a light transmitting sensor, acquires information for determining the storage capacity of the rubber stoppers C in the rubber stopper temporary storage portion 41, and outputs the acquired information to the control unit 70.
Specifically, as shown in fig. 1, the rubber stopper temporary stock quantity acquiring unit 60 is provided in the vicinity of the rubber stopper receiving mouth 41a of the rubber stopper temporary storage portion 41, detects whether or not the rubber stopper C supplied from the rubber stopper adding direction supplying unit 30 is stored in the rubber stopper receiving mouth 41a, and outputs a detection signal thereof to the control unit 70.
The rubber stopper temporary stock quantity acquiring unit 60 is exemplified as a light transmission sensor, but the present invention is not limited thereto, and other types of sensors may be used. In the case where the light transmission sensor is not used as the rubber plug temporary stock quantity acquiring unit 60, the rubber plug temporary housing portion 41 may not be made of a light-transmissive resin material.
The control unit 70 includes a CPU and the like, and controls each unit of the wire coating and removing unit 1. More specifically, when a signal indicating that the insulation coating removal process is to be started is output from the operation unit 50, the control unit 70 starts the insulation coating removal process.
The control section 70 has a rubber stopper supply control section 71.
The rubber stopper supply control unit 71 determines whether or not the rubber stopper C is accommodated in the rubber stopper temporarily accommodating portion 41 by a predetermined amount or more based on the information for determining the rubber stopper C accommodating amount output from the rubber stopper temporarily storing amount acquiring unit 60, and supplies the rubber stopper C with the orientation added thereto to the rubber stopper temporarily accommodating portion 41 by the rubber stopper adding direction supplying unit 30 when it is determined that the rubber stopper C accommodated in the rubber stopper temporarily accommodating portion 41 is less than the predetermined amount.
More specifically, when the light transmission sensor of the rubber stopper temporary storage amount acquiring unit 60 outputs a signal indicating that light is transmitted therethrough, the rubber stopper supply control unit 71 determines that the rubber stoppers C in the rubber stopper temporary storage portion 41 are less than a predetermined amount, and drives the driving units 33, 33 of the rubber stopper feeding direction supplying unit 30.
Next, a manufacturing step of removing the insulation coating W2 of the terminal portion W1 of the electric wire W using the electric wire coating removal unit 1 and inserting the electric wire W into the rubber stopper C will be described with reference to fig. 7 and 8.
Fig. 7(a) is a view showing a state where the electric wire W is inserted through the rubber stopper C and inserted into the insertion port 12 of the electric wire coating removal part 10, and (b) is a view showing a state where the electric wire coating removal part 10 is removing the insulation coating of the electric wire W after the step of (a). Fig. 8(c) shows a state where the insulation coating removal process by the wire coating removal unit 10 is completed and the clamping of the wire W is released, and (d) shows a state where the wire W after the insulation coating removal process by the wire coating removal unit 10 is pulled out from the insertion port 12.
First, as a rubber stopper insertion step, the operator inserts the wire W into the rubber stopper C and into the insertion port 12 of the wire coating and removing part 10 (see fig. 7 a). In this operation, the operator inserts the wire W into the insertion hole C1 of the rubber stopper C located at the wire insertion position 41b in the rubber stopper temporary housing portion 41, and the distal end portion W1 of the wire W is held by the rubber stopper C and is inserted into the insertion port 12 of the wire coating and removing portion 10 while being guided.
The rubber stopper disposing step is performed before the step of collectively inserting the rubber stopper and removing the insulation coating by disposing the rubber stopper C at the electric wire insertion position 41b by the rubber stopper disposing part 40.
After that, the operator operates the operation unit 50 to start the insulation coating removal process by the wire coating removal unit 10 (see fig. 7 b). Here, the operator moves the wire coating removal unit 10 by pressing down a foot switch as the operation unit 50 with his foot. More specifically, the cutter 11 is movable after the wire W is clamped by the clamp 13 located inside the insertion port 12 of the wire coating and removing part 10.
After that, when the insulation coating removal process by the wire coating removal unit 10 is completed and the clamp of the wire W by the clamp unit 13 is released (see fig. 8 c), the operator pulls the wire W out of the insertion port 12 to complete the operation (see fig. 8 d).
Here, when the operator pulls out the electric wire W from the insertion port 12 of the wire coating and removing unit 10, the openable and closable door 42 provided at the wire insertion position 41b of the rubber plug temporary housing 41 is pushed from the inside by the rubber plug C pulled out together with the electric wire W and is opened, so that the rubber plug C is pulled out in a state where the electric wire W is inserted.
When the rubber stopper C is pulled out from the wire insertion position 41b, the rubber stopper C placed on the pulled-out rubber stopper C moves by its own weight, and the next rubber stopper C is disposed at the wire insertion position 41 b.
In the wire coating and removing unit 1 according to embodiment 1 of the present invention, since the operator inserts the wire W into the insertion hole C1 of the rubber stopper C held at the wire insertion position 41b, and the distal end portion W1 of the wire W is held by the rubber stopper C and is inserted into the insertion port 12 of the wire coating and removing unit 10 while being guided, the distal end portion W1 of the wire W can be easily guided to the insertion port 12 of the inserted wire W toward the insulation coating cutter 11 from which the distal end portion W1 of the wire W is removed, and the wire W can be easily inserted into the rubber stopper C.
In the wire coating and removing unit 1 according to example 1 of the present invention, since the rubber stoppers C can be continuously supplied from the rubber stopper housing part 41 to the wire insertion position 41b by the rubber stopper adding direction supplying part 30, the rubber stoppers C can be omitted from being placed at the wire insertion position 41 b.
In the wire coating and removing unit 1 according to example 1 of the present invention, the rubber stopper supply control unit 71 controls the rubber stopper adding direction supplying unit 30 based on the information acquired by the rubber stopper temporary stock quantity acquiring unit 60 so that the rubber stoppers C in the rubber stopper temporary housing portion 41 do not become short, and therefore the rubber stoppers C disposed at the wire inserting position 41b can be supplied without becoming short.
In addition, the wire coating and removing unit 1 according to example 1 of the present invention can move the rubber stopper C from the rubber stopper receiving nozzle 41a to the wire insertion position 41b by its own weight without using a driving mechanism, and therefore can be manufactured as a simple device configuration.
In the method of manufacturing a wire harness according to example 1 of the present invention, since the operator inserts the wire W into the insertion hole C1 of the rubber stopper C disposed at the wire insertion position 41b, and the distal end portion W1 of the wire W is held by the rubber stopper C and is inserted into the insertion port 12 of the wire coating and removing unit 10 while being guided, the distal end portion W1 of the wire W can be easily guided to the insertion port 12 of the inserted wire W toward the cutter 11 of the insulation coating W2 from which the distal end portion W1 of the wire W is removed, and the wire W can be easily inserted into the rubber stopper C.

Next, an electric wire coating and removing unit 2 according to example 2 of the present invention will be described with reference to fig. 9.
Fig. 9 is a perspective view of the wire coating and removing unit 2 according to embodiment 2 of the present invention.
