Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for inserting an auto fuse.

[0002]

2. Description of the Related Art In general, a large number of different types of auto fuses are inserted into a fuse box connected to a wire harness. These multiple types of auto fuses
The wire harness is selected according to the product number of the fuse box, and it is necessary to insert the wire harness in the fuse box in a unique combination and arrangement for each wire harness.

Therefore, conventionally, a technique for inserting an auto fuse into a fuse box has been proposed.
For example, in Japanese Utility Model Laid-Open No. 3-20855, an auto-fuse that is pre-aligned with a multi-groove member that can be mounted on a fuse box is positioned, and the positioned auto-fuses are collectively pushed by a comb-shaped pressing member. A technique has been proposed in which an auto fuse is loaded into a fuse box by applying pressure. In this prior art, when positioning the auto fuse in the multi-groove member, a laminated set member filled with a large number of auto fuses in a laminated state is provided. When the pressing member penetrates in the mounted state, the auto fuse can be supplied from the laminated set member to the fuse box via the multi-groove member.

However, in the structure described in Japanese Utility Model Laid-Open No. 3-20855, no means for changing the auto fuse or the arrangement thereof is provided for each part number of the fuse box. On the other hand, in Japanese Examined Patent Publication No. 58-9533, an auto-fuse that has been separated by a parts feeder is fed to an alignment holder that holds a single row and then guided by a flexible chute so that it falls on the fuse box. There is disclosed a technique of dropping an auto fuse on a positioning member placed on the. This Japanese Patent Publication No. 58-9533 also proposes a technique of automatically inserting a large number of different types of auto fuses of the same size and size with a single device. In this configuration, a stock member filled with a plurality of types of auto fuses is branch-wired to the alignment holder described above, and the auto fuses to be fed to the alignment holder are sent according to the auto fuse to be selected. It was possible to change the type of auto fuse by switching the supply path.

[0005]

By the way, in a recent wire harness, a device having good workability is required for general-purpose use of an auto-fuse insertion system in response to production of a large number of products in small quantities. In this respect, although the technique of Japanese Patent Publication No. 58-9533 can be generalized to a certain extent, when the auto fuse is switched, the operator does the auto fuse based on the instruction. Since it was necessary to check each product number etc.
Workability is poor and mistakes are likely to occur. Particularly in recent years, the number of insertion patterns of auto fuses may increase to dozens of types. Therefore, it is impossible to rely only on the collation skill of the worker, and the yield becomes poor.

Further, since the aligned auto fuses are fed by the flexible chute to the alignment holding body which is positioned in advance in the fuse box, the parts feeder, etc. are placed within the movable range of the fuse box attached to the wire harness. However, there is a problem that the work space is narrowed. Further, since the supply path of the auto fuse is branch-wired, as the type of the auto fuse becomes larger, the whole insertion system becomes much larger, which is not preferable.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a device for inserting an auto fuse having good workability, which is suitable for high-volume low-volume production.

When the handle 64 is rotated from the initial posture shown in FIG. 17A, the link bar 64E rotates about the horizontal axis 63 along the arc upper surface 91 of the cam hole 65B, and finally the arc. It deviates from the upper surface 91 and is displaced toward the horizontal upper surface 92. As a result, as shown in FIG. 17B, the connection between the cam plate 65A and the link bar 64E is released, so that the carrying member 65 is displaced downward by its own weight while being buffered by the compression coil spring 68. You can do it.

In the illustrated specific example, the protrusion height of the auto fuse F can be detected by the displacement amount of the carrying member 65. 18 (A) and 18 (B), the carrying member 65 is provided with an elevating member 92 which is displaceable integrally therewith.
Are set to connect a limit switch 93 fixed to the back plate 61. This limit switch 93
Is set to a position which is connected when the pressing member 66 comes into contact with the auto-fuse F which has been properly preliminarily inserted, and is connected when the carrying member 65 is at a position higher than that. There is no such thing.

Further, the back plate 61 has an air cylinder 94.
Is attached, and its rod 95 has a handle 6
The rotation of the handle 64 is prevented at a stage before the pressing member 66 comes into contact with the auto-fuse F which is normally pre-inserted, by interfering with the protrusion 96 provided on the horizontal shaft 63 of No. 4. Therefore, the rod 95 is retracted only when the limit switch 93 is connected to allow the handle 64 to rotate.

Next, the cam plate 65A and the link bar 6
FIG. 18A shows the operation after disconnection from the 4E.
This will be described with reference to (B). According to the mechanism described above, when the auto fuse F is properly preliminarily inserted, as shown in FIG. 18 (A), the carrying member 65 can be lowered to connect the limit switch 93. The rod 95 of the air cylinder 94 retracts. As a result, the handle 64 can be further rotated, so that the pressing member 66 is provided with the bearing 64C of the handle 64.
Comes into rolling contact with the carrying member, pushes in the carrying member 65, and the auto fuse F is inserted.

On the other hand, as shown in FIG. 18B, when the auto fuse F is mounted on the terminal fitting 5, the pressing member 66 cannot be lowered, so that the carrying member 65, which is displaced integrally with the pressing member 66, is moved up and down. The member 92 is also prevented from descending, and the limit switch 93 cannot be connected. As a result, even if the handle is rotated further, the protrusion 96 of the handle 64 interferes with the rod 95 of the air cylinder 94, and the forced pressing by the pressing member 66 is prevented. In the specific example shown in the figure, the height difference h between the auto fuse F when the vehicle is running and the auto fuse F on which the regular pre-insertion is performed is, for example, 2 to 3 mm.
Is.

As described above, according to the above-described embodiment, the auto fuses F are aligned in a desired arrangement prior to placing the main body 11 of the auto fuse holding device 10 on the fuse box 1. Since it is not necessary to convey the means for feeding and loading the auto fuse F to the fuse box 1, as a result, the insertion work can be performed within the movable range of the fuse box 1 attached to the wire harness 6. The advantage is that

Further, in the loading device 20 described above,
Since the auto fuse F is selected by mechanically identifying the type (product number) by identifying the product number using the barcode, mistakes due to human factors can be reduced as much as possible even when performing high-mix low-volume production. The advantage is that Moreover, in the above-described auto fuse stock device 30, after all the auto fuses F necessary for one fuse box 1 have been taken out, they are inserted into the next fuse box 1 by one driving operation by the feeding means. Since it is possible to feed out the proper auto fuse, it is possible to realize the sequential feeding of the auto fuse with a simple mechanism, and there is an advantage that feeding failure is less likely to occur due to the simplification of the mechanism.

Further, in the insertion device 50 according to the above-described embodiment, in the process of displacing the carrying member 65 from the retracted position to the pressurizing position by the handle 64 as an operating mechanism, the shutter drive mechanism 80 is previously set to the closed position. Since a certain shutter 15 can be displaced to the release position, there is an advantage that the insertion work can be performed by one operation. In addition, the compression coil spring 88 causes the carrying member 65 to return from the pressurizing position to the retracted position.
Since the automatic fuse holding device 10 does not follow the carrying member 65, there is an advantage that the automatic fuse holding device 10 can be easily handled.

In the above-described insertion device 50, the press portion 60 is reciprocally movable by the slider portion 70, so that the fuse box 1 and the automatic fuse holding device 10 mounted on the fuse box 1 are released. Therefore, there is an advantage that the attachment / detachment work of the fuse box 1 and the attachment / detachment work of the automatic fuse holding device 10 are facilitated.

Further, by determining whether or not the pre-insertion state of the auto fuse F is appropriate, the insertion operation is forcibly stopped in the case of the pre-insertion failure, so that the occurrence of defective products can be prevented. There is an advantage that you can. As described above, according to the embodiment of the present invention, there is a remarkable effect that it is possible to realize a device having a good workability, which is suitable for the production of a large number of products in small quantities.

The above-described embodiment is merely an example of a preferred example of the anti-invention, and the present invention is not limited to the above-described embodiment. It goes without saying that various design changes can be made within the scope of the claims of the present invention.

[0064]

As described above, according to the first aspect of the invention, since the auto fuses can be aligned in a desired arrangement prior to placing the main body portion on the fuse box, the auto fuses are sent. As a result, it is no longer necessary to transport the feeding and loading means to the fuse box,
There is an advantage that the insertion work can be performed within the movable range of the fuse box attached to the wire harness.

According to the second aspect of the invention, in the process of displacing the carrying member from the retracted position to the pressurizing position by the operating mechanism, the shutter drive mechanism can displace the shutter which is in the closed position in advance to the open position. Therefore, there is an advantage that the insertion work can be performed by one operation. Further, in the invention according to claim 3, since the auto fuse holding device does not follow the carrying member in the process of returning the carrying member from the pressurization position to the retracted position, there is an advantage that the auto fuse holding device is easily handled. is there.
