Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus 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 in accordance with the product number of the hue box, and it is necessary to insert the wire harness into the fuse box in a unique combination and arrangement for each wire harness.

Therefore, a technique for inserting an auto fuse into a fuse box has been conventionally proposed.
For example, Japanese Utility Model Laid-Open Publication No. Hei 3-20855 discloses that a pre-aligned auto fuse is positioned in a multi-groove member that can be mounted on a fuse box, and the positioned auto fuses are simultaneously pressed 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 the prior art, when positioning the auto fuse in the multi-groove member, a stacked set member in which a large number of auto fuses are filled in a stacked state is provided, and the stacked set member is placed on the multi-groove member. When the pressure 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 configuration described in Japanese Utility Model Laid-Open No. Hei 3-20855, no means has been taken for changing the auto fuses and their arrangement for each fuse box product number. On the other hand, Japanese Patent Publication No. 58-9533 discloses that an auto fuse handled by a parts feeder is fed to an alignment holder which holds a single row, and then guided by a flexible chute so as to fall on the fuse box. There is disclosed a technique for dropping an auto fuse into a positioning member mounted on a vehicle. In Japanese Patent Publication No. 58-9533, there is also proposed a technique for automatically inserting auto fuses of the same shape and the same size having different capacities by a single device. In this configuration, a stock member filled with a plurality of types of autofuses is spliced and connected to the above-described alignment holder, and the autofuses supplied to the alignment holder are fed according to the selected autofuse. By switching the supply path, the type of the auto fuse can be changed.

[0005]

By the way, in recent years, in a wire harness, an apparatus having good workability has been demanded in order to widely use an auto-fuse insertion system in response to the production of a large number of products in small quantities. In this regard, the technique disclosed in Japanese Patent Publication No. 58-9533 allows generalization to some extent. However, when switching autofuses, an operator needs to perform autofusing based on instructions. And part number, etc.
Workability is poor and mistakes are likely to occur. In particular, in recent years, since the number of insertion patterns of the auto fuse has increased to several tens of cases, it is impossible to rely solely on the collation skill of the operator, and the yield is deteriorated.

Further, since the aligned auto fuses are fed by a flexible chute to an alignment holder preliminarily positioned in the fuse box, a part feeder or the like is set within a movable range of the fuse box attached to the wire harness. However, there is a problem that the work space is narrowed. In addition, since the supply route of the auto fuse is connected and connected, the entire mounting system is unnecessarily large as the type of the auto fuse is increased, which is not preferable.

FIGS. 16A and 16B are schematic side sectional views of the auto-fuse insertion device shown in FIG. 12, wherein FIG. 16A shows a state of being displaced to a retracted position and FIG. As shown in FIGS. 3A and 3B and FIGS. 3A and 3B, in the above configuration, when the support member 65 is at the upper evacuation position, the pressing bar 84 is stopped. The pressure receiving portion 15B of the auto-fuse holding device 10 which is located at the right side. When the handle 64 is rotated in this state, the pressing member 66
Prior to pressurizing the auto fuse F, the pressing bar 84 presses the pressure receiving portion 15B to displace the shutter 15 to the release position as shown in FIG. As a result, the auto-fuse F is dropped into the cavity 3 to realize the pre-insertion, and then the pressing member 66 presses the auto-fuse F, thereby realizing the actual insertion. In the specific example shown in the drawing, in the process in which the pressing member 66 returns to the retracted position after the actual insertion, the automatic fuse holding device 10
In order to prevent the follower from following, in the process of returning the holding member 65 from the pressing position to the retracted position, the holding member 65 is provided with a compression coil spring 88 for pressing the auto-fuse holding device 10 against the fuse box 1. I have.

When the pre-insertion of the auto-fuse F is incomplete, for example, when the auto-fuse F runs over the terminal fitting 5 in the fuse box 1, the pressing member 66 pushes the auto-fuse F. Otherwise, a defective product may be generated. Therefore, in the illustrated specific example, the following mechanism is adopted. FIG.
2A and 2B are schematic side views showing one element of a height detecting means employed in the automatic fuse mounting device of No. 2; FIG. 2A shows an initial posture before the operation is started, and FIG. FIGS. 18A and 18B schematically show the height detecting means and the stop mechanism employed in the auto-fuse insertion device shown in FIG. 12, wherein FIG. 18A shows a normal state, and FIG. FIG.

First, as shown in FIGS. 17A and 17B,
In order to connect the carrying member 65 and the operation mechanism 62, a cam hole 65B is formed in a cam plate 65A screwed to the carrying member 65. The cam hole 65B includes an arc-shaped upper surface 91 concentric with the horizontal shaft 63 and a horizontal upper surface 92 extending in a direction intersecting with the arc-shaped upper surface 91. As described above, the handle 64 is supported so as to be rotatable around the horizontal axis 63, and also as shown in FIG.
As shown in FIG. 19, by locking the above-mentioned circular arc upper surface 91 to the link bar 64E, the cam plate 65A is connected to the carrying member 65 in a state of being lifted upward.

When the handle 64 is rotated from the initial position shown in FIG. 17A, the link bar 64E is rotated around the horizontal axis 63 along the arc upper surface 91 of the cam hole 65B, and finally the arc is formed. It is displaced from the upper surface 91 to the horizontal upper surface 92 side. As a result, as shown in FIG. 17B, the connection between the cam plate 65A and the link bar 64E is disconnected, so that the supporting member 65 is displaced gently downward while being buffered by the compression coil spring 68 by its own weight. I can do it.

In the specific example shown in the drawing, the protruding height of the auto fuse F can be detected based on the displacement of the support member 65. Referring to FIGS. 18A and 18B, an elevating member 92 that can be displaced integrally therewith is attached to the supporting member 65.
Is set to connect a limit switch 93 fixed to the back plate 61. This limit switch 93
Is set to a position where the pressing member 66 is brought into contact with the auto-fuse F which has been properly pre-inserted, and is connected when the supporting member 65 is at a higher position than that. Not to be.

Further, an air cylinder 94 is provided on the back plate 61.
The rod 95 is attached to the handle 6.
4, 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 properly pre-inserted. Only when the limit switch 93 is connected, the rod 95 is retracted to allow the handle 64 to rotate.

Next, the cam plate 65A and the link bar 6
FIG. 18A shows the operation after the connection with 4E is disconnected.
This will be described with reference to FIG. According to the above-described mechanism, when the auto fuse F is properly preliminarily inserted, as shown in FIG. 18A, the support member 65 can be lowered, so that the limit switch 93 is connected. The rod 95 of the air cylinder 94 retracts. As a result, the handle 64 can be rotated thereafter, so that the pressing member 66
Makes rolling contact with the support member, pushes the support member 65, and the auto fuse F is inserted.

On the other hand, as shown in FIG. 18B, when the auto fuse F rides on the terminal fitting 5, the pressing member 66 cannot be lowered, so that the carrying member 65 displaced integrally with the pressing member 66 is raised and lowered. The member 92 is also prevented from descending, and the limit switch 93 cannot be connected. As a result, even if the handle is further rotated, the projection 96 of the handle 64 interferes with the rod 95 of the air cylinder 94, and the forcible pressing by the pressing member 66 is prevented. In the specific example shown in the drawing, the difference h in height between the auto fuse F when riding and the auto fuse F in which regular preliminary insertion is performed is, for example, 2 to 3 mm.
It is.

As described above, according to the above-described embodiment, the auto fuses F are arranged in a desired arrangement prior to placing the main body 11 of the auto fuse holding device 10 in the fuse box 1. As a result, there is no need to transport the means for feeding and loading the auto-fuse F to the fuse box 1, and as a result, the insertion work can be performed within the movable range of the fuse box 1 attached to the wire harness 6. There is an advantage that can be.

In the loading device 20 described above,
Since the auto fuse F is selected by mechanically specifying the type (product number) by specifying the product number using a bar code, mistakes caused by human factors should be reduced as much as possible even when performing high-mix low-volume production. There is an advantage that can be. In addition, in the above-described auto fuse stock apparatus 30, after all the necessary auto fuses F for one fuse box 1 are 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 an autofuse to be advanced, it is possible to realize the forward feeding of the autofuse by a simple mechanism, and there is an advantage that the feeding is less likely to occur due to the simplification of the mechanism.

In the insertion device 50 according to the above-described embodiment, in the process of displacing the holding member 65 from the retracted position to the pressing position by the handle 64 as an operating mechanism, the shutter driving mechanism 80 is previously moved 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, in the process of returning the holding member 65 from the pressurized position to the retracted position by the compression coil spring 88,
Since the auto fuse holding device 10 does not follow the supporting member 65, there is an advantage that the handling of the auto fuse holding device 10 becomes easy.

In the above-described insertion device 50, the press unit 60 is reciprocally movable by the slider unit 70, thereby releasing the fuse box 1 and the automatic fuse holding device 10 mounted on the fuse box 1. Therefore, there is an advantage that the work of attaching and detaching the fuse box 1 and the work of attaching and detaching the auto fuse holding device 10 become easy.

Further, by judging whether the pre-insertion state of the auto fuse F is proper or not, the insertion operation is forcibly stopped in the case of the pre-insertion failure, so that occurrence of defective products can be prevented beforehand. There is an advantage that you can. As described above, according to the embodiment of the present invention, there is a remarkable effect that an apparatus with good workability suitable for high-volume small-quantity production can be realized.

The above embodiment is merely an example of a preferred specific example of the present invention, and the present invention is not limited to the above embodiment. It goes without saying that various design changes are possible within the scope of the claims of the present invention.
