Description

Detailed Description of the Invention (Industrial Field of Application) The present invention involves attaching a door removed from a vehicle body to a transport jig at a door removal station, and then supporting the broadcasting jig on a carry-out conveyor and carrying it out. Then, together with the conveyance jig (after performing predetermined processing on the ejected door and reattaching the door to the vehicle body), the conveyance jig is supported on the carry-in conveyor and transferred to the door removal station ( The present invention relates to a device that, in an assembly line for automobiles, receives a conveying jig to which the door is to be attached from the incoming conveyor, while the conveying jig with which the door is to be installed is placed onto the unloading conveyor.

(Prior art) On an automobile assembly line, for example, when each automobile is given travel equipment, each door is once removed from the body of each automobile at a door removal station, and the automobile body and each door are assembled separately. It is generally known that the two parts are then reassembled at a door installation station.
Each door removed from the vehicle body is transported from the door removal station to the door mounting line, where the left and right doors are individually transported and mounted, and then the doors are removed from the mounting line. Transported to installation station.

Conventionally, in this type of assembly line, it was necessary to transport and install the left and right doors separately on the door loading line, so the left and right doors were generally moved from the door removal station to the loading line. and the section from the travel equipment line to the door attachment station.

However, in such an assembly line, there are many transport paths for the doors, and a large number of transport jigs are also required to transport each door by a conveyor, etc., which inconveniently increases the size of the assembly line. there were.

Therefore, the present applicant has proposed the following assembly line in order to eliminate such inconvenience.

That is, in this assembly line, the left and right doors removed from the car body are attached to a pair of transport jigs that are separably connected at the door removal station, and after installation, the left and right doors are removed from the vehicle body. From the station to the loading station of the travel equipment line, the re-conveying jig is arranged in parallel in the width direction on the same loading conveyor, which is composed of a roller conveyor, etc., and is integrally conveyed with the broadcasting jig.

Next, after separating both transport jigs at the loading station, the left and right doors are separately loaded together with one general transport jig onto a pair of conveyors such as a shuttle conveyor attached to the travel equipment line. In the loading line, each door is transported together with each conveyor jig on each conveyor and loaded.

After the loading, each door is discharged from the conveyor together with each transport jig at the unloading station of the travel equipment line, while both transport jigs are connected again. From the dispensing station to the door attachment station, both conveying jigs are arranged side by side in the width direction on the same dispensing conveyor constituted by a roller conveyor or the like, and are integrally conveyed with both conveying jigs.

Further, both doors transported to the door mounting station together with the transport jig are removed from the transport jig and attached to the vehicle body at the door mounting station, and after this, both the transport jigs are The doors are transported from the door installation station to the door removal station on a returning conveyor comprised of a roller conveyor or the like, and at the door removal station both doors are attached again and placed onto the input conveyor, The door is removed from the door removal station.

In this case, this assembly line is structured three-dimensionally in order to efficiently utilize the space within the equipment, and includes, for example, an input conveyor for conveying the doors and conveyance jigs, an unloading conveyor, and a return conveyor. Conveyors and the like are provided on the third floor, and the travel equipment line, vehicle body conveyance line, etc. are provided on the first and second floors.

According to such an assembly line, especially in the front and rear sections of the travel equipment line, the left and right doors removed from the vehicle body are conveyed integrally on the same conveyor via a pair of mutually connected conveyor jigs. In addition, by constructing the conveyor by a roller conveyor or the like that does not require a return path, the structure related to the conveyance of each door can be made compact, and the assembly line can be downsized.

In addition, since both doors are transported from the door removal station to the same transport jig at the installation station, the number of transport jigs required for the assembly line can be reduced. I can do it.

In this way, such deviations in the assembly line are effective in reducing the size of the line configuration. And furthermore,
In order to simplify and compact the configuration of this assembly line, and to efficiently transport the left and right doors removed from the vehicle body from the door removal station via the travel equipment line to the door installation station, it is necessary to At the outer station, a transport jig with a door attached is put into the input transport conveyor, and an empty transport jig is received from the door installation station via the return transport conveyor to the door removal station. At the same time, the transfer jig can be loaded and received efficiently, and
(Return)) The transport jig received from the broadcast conveyor,
What is desired is a device that can continuously and efficiently perform the task of reattaching the door and loading the materials onto the loading conveyor.

(Problems to be Solved) In consideration of this background, the present invention has been developed by attaching the door removed from the vehicle body to a transport jig at a door removal station, and then supporting the transport jig on a carry-out conveyor and carrying it out.

Then, as shown in FIG. 5(C), in a state where the input conveyor 24 and the receiving conveyor 25 are connected to the input conveyor 22 and the receiving conveyor 23, respectively, the transfer jig 6 is transferred between them.

(Effects) As is clear from the above description, according to the input receiving device of the present invention, the first input conveyor and the first receiving conveyor can be moved to the raised position where they are connected to the output conveyor and the input conveyor, respectively, and to the door installation. The second input conveyor and the second receiving conveyor are integrally moved back and forth in the width direction by the moving means, while the second input conveyor and the second receiving conveyor are integrally moved up and down between the outer station and the lowered position which is approximately the same height as the outside station by the lifting means. By connecting the input and receiving conveyors alternately,
When moving to either of them, it is connected to the first input conveyor and the first receiving conveyor at the lowered position, and between the first input conveyor and the first receiving conveyor and the output conveyor and the input conveyor. The conveyance jig is exchanged between the second input conveyor, the second receiving conveyor, and the input reception conveyor when they are respectively connected, while the conveyance jig is exchanged between the second input conveyor, the second receiving conveyor, and the input reception conveyor when they are respectively connected alternately. and the first input conveyor and the first
The transfer jig is transferred between the receiving conveyor, the second input conveyor, and the second receiving conveyor when they are connected, so that the transfer jig with the door attached can be input to the output conveyor, and the door It is possible to efficiently receive the transport jig to be attached from the carry-in conveyor, as well as to reattach the door to the fastest jig (received from the carry-in conveyor) and then to feed it again to the carry-out conveyor in a continuous and efficient manner. As a result, the configuration of the input receiving device can be simplified.
