Description

[Detailed description of the invention] (Industrial application field) This invention moves parts or tools in synchronization with the slat conveyor and returns them to their original positions in an assembly line using a slat conveyor. Regarding a conveyance device.

(Prior Art) Conventionally, when assembling parts with parts to be assembled placed on a slat conveyor, a worker would pick up the parts or tools from a parts stand or a tool stand provided next to the conveyor in the assembly work area. The work involves taking out the parts, assembling the parts with the parts to be assembled using the tool, and returning the tool to the tool stand.

(Problems to be Solved by the Invention) However, the above-mentioned work has a problem in that the efficiency of the work is reduced due to movement to the component stand or tool stand.

As a means to solve the above problems, for example, there is a parts supply device in which a moving member that moves back and forth on a rail provided on a slat conveyor has a parts holder and an air cylinder that moves up and down. 55−59608).

However, in the above-mentioned parts supply apparatus, the movement of lowering the parts at the parts assembly position, moving them together with the slat conveyor, and raising them after the parts assembly is automatically controlled, makes the apparatus structure, control circuit, etc. complicated.

The present invention was developed in view of the above-mentioned problems, and its purpose is to eliminate the need for workers to move to set aside parts or tools when assembling parts onto parts to be assembled on a slat conveyor. An object of the present invention is to provide a simple synchronization device.

(Means for Solving the Problems) In order to achieve the above object, the synchronizing device of the present invention is provided so as to be movable back and forth along a rail provided above the slat conveyor and parallel to the slat conveyor. a slide member, a crimping member that is positioned on the slat conveyor and moves together with the slat conveyor by being crimped to the slat conveyor; and a crimping member that connects the slide member and the crimping member and has a mounting table for parts or tools. It is characterized by comprising a connecting member provided and a return means for returning the connecting member to the standby position by releasing the crimping.

(Function) When the parts to be assembled on the slat conveyor pass through the synchronizer having the above structure, the operator rides on the crimping member. Then, the crimping member is crimped onto the slat conveyor, and the synchronizer and the worker move together with the slat conveyor against the return force of the return means. During the movement, the operator takes out the parts or tools from the mounting table provided on the support member of the synchronizer and assembles the parts to the part to be assembled. After the assembly work is completed,
When the operator returns the tool and gets off the crimping member, the synchronizer returns to the standby position by the return force of the return means.

(Example) Figures 1 and 2 show part of an assembly line in which equipment parts are assembled on a car body W. The car body W is placed on a slat conveyor 1 and conveyed in the direction of arrow A. Ru.

In FIG. 1, the rail 2 is provided above and parallel to the slat conveyor 1.

The synchronizer S includes a slide member 3, a rubber mat 5 as a pressure bonding member, a connecting member 6, and a hose reel 12 as a return means.

The slide member 3 is provided with rollers 4, 4, and is movable along the rail 2 in the front and rear directions (right and left directions in the figure). A rubber mat 5 is placed on the slat conveyor 1 facing the slide member 3 with a gap of approximately 20 to 30 mm. A connecting member 6 is vertically provided on the slide member 3 facing the slat conveyor 1. A connecting plate 7 is provided at the lower end of the connecting member 6, and the rubber mat 5 is joined to the connecting plate 7 with bolts or the like. Further, the connecting member 6 is provided with a holder 9 for bolts and nuts for assembling parts (not shown), and a tool holder 10 for an impact wrench 11 for fastening the bolts. The rail 2 is provided with a hose reel 12 around which a reel 13 is wound by a spring force, and a stopper 14 is provided between the hose reel and the slide member 3.

One end of the reel 13 is engaged with the connecting member 6, and the return force of the reel 13 causes the slide member 3 to come into contact with the stopper 14, and the synchronizer is stopped at the standby position.

Note that a reinforcing member 8 is provided between the slide member 3 and the connecting member 6.

Next, the operation of the synchronizer having the above structure during assembly will be explained. Slut conveyor 1
The front panel 15 of the upper automobile body W is opened in the previous process, and an air cleaner (not shown) as an assembled part is placed in the engine room. The synchronizer S in which the air cleaner mounting part of the automobile body W is in the standby position shown in FIG.
When the worker O approaches the rubber mat 5, the worker O gets on the rubber mat 5. Then, the rubber mat 5 is pressed onto the slat conveyor 1 by the weight of the worker, and the synchronizer S and the worker move onto the reel 13 together with the slat conveyor 1.
begins to move against the restoring force. As shown in FIG. 2, the operator O, riding on the rubber mat 5, takes out the bolts and nuts from the component holder 9 and the impact wrench 11 from the tool holder 10. Then, bolt the above air cleaner,
Assemble in place with nuts and impact wrench 11.

After completing the assembly work, the worker O returns the impact wrench 11 to the tool holder 10 and attaches it to the rubber mat 5.
get off from Then, the synchronizer S moves toward the hose reel 12 due to the return force of the reel 13, and is stopped at the standby position by the stopper 14. The worker O returns to the vicinity of the standby position and waits for the next assembly operation.

(Effect of the invention) From the above explanation, according to the device of the present invention, parts or tools can be placed on the slat conveyor and assembly work can be performed, so the movement for placing parts or tools is easy. gone,
Work efficiency improves. Furthermore, this device has a simple structure that does not require a cylinder, a control circuit, etc., and can be implemented at a lower cost than conventional devices.
