Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention prevents foreign matter such as lubricating oil that falls from the guide rails and drive chains that make up the overhead conveyor from adhering to workpieces such as bumpers that are being transported by the overhead conveyor in the painting process of automobile manufacturing plants. The present invention relates to a device for preventing foreign matter from adhering to an overhead conveyor.

[0002]

[Prior art]

 If foreign matter such as lubricating oil adheres to the work surface during transport after the foreign matter on the surface of the work is washed away by pretreatment, appearance defects may occur on the surface where foreign matter such as lubricating oil adheres after painting. Become. Therefore, in order to prevent falling foreign matter such as lubricating oil from adhering to a work conveyed by a hanger, a one tray is provided on the upper part of the hanger, and it is described in Japanese Utility Model Laid-Open No. 63-8223. It is known that a dust receiver is provided along the lower part of the rail of the overhead conveyor.

[0003]

[Problems to be solved by the device]

 In the former one of those mentioned in the prior art, covering the entire work such as a bumper with a single saucer would result in a large area, and interference with other transportation equipment and production equipment would occur in a densely packed factory. However, if the tray is made small, the work cannot be protected from the adhesion of foreign matter, and the purpose of preventing the attachment of falling foreign matter cannot be reliably achieved. Was.

Further, in the latter case, since hundreds of hangers are constantly traveling, foreign matter may fall into the dust receiver due to vibration during transportation and passing of the trolley through the step of the seam of the rail, and the hanger may be inclined. There was a problem that foreign substances adhered to the work because foreign substances could concentrate and overflow from the dust receiver in a certain place.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to prevent other problems when the work is carried by the overhead conveyor in a dense factory. It is possible to reliably prevent foreign matter such as lubricating oil that falls from the drive chain from adhering to the work without interfering with the production equipment of the above, and to easily remove the foreign matter such as the dropped lubricating oil. It is intended to provide a foreign matter adhesion preventing device.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is to suspend foreign matter such as lubricating oil falling from a guide rail or a drive chain on a work carried by a hanger that is suspended by a guide rail and travels by a hook attached to the drive chain. In a foreign matter adhesion prevention device for an overhead conveyor for preventing adhesion, a tray for a plurality of divided falling foreign matters is provided below a hanger support member that supports the hanger. In addition, a detachable seat member that adheres or absorbs foreign matter such as lubricating oil may be attached to the tray.

[0007]

[Action]

 Even if foreign matter such as lubricating oil falls due to vibration during transportation and the hanger support member passing through the step of the seam of the guide rail, the foreign matter will fall into the saucer that is divided into multiple parts. Does not adhere to. In addition, the foreign matter that has fallen can be absorbed and easily removed by the sheet member attached to the tray.

【Example】

 Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of an overhead conveyor equipped with a foreign matter adhesion prevention device for an overhead conveyor according to the present invention, and FIG. 2 is a side view of an inclined portion of an overhead conveyor equipped with the foreign matter adhesion prevention device for an overhead conveyor according to the present invention. FIG. 3 and FIG. 3 are schematic plan views of a swivel portion of an overhead conveyor equipped with a foreign matter adhesion prevention device for an overhead conveyor according to the present invention.

The overhead conveyor 1 is pulled by a drive chain rail 2, a drive chain 3 provided in the drive chain rail 2, hooks 4 provided at predetermined intervals on the drive chain 3, and a hook 4. It consists of hangers 5. The hanger 5 is supported by two trolleys 7 guided by a guide rail 6 arranged below the drive chain rail 2.

A receiving tray 8 is attached below the two trolleys 7. In addition, trolleys 9 and 10 guided by the guide rail 6 are provided in front of and behind the two trolleys 7, and trays 11 and 12 are attached to the lower portions of the trolleys 9 and 10, respectively. The top trolley 9 is provided with a pusher 13 that hooks on the hook 4.

The front and rear trolleys 9 and 10 are flexibly connected to the middle trolley 7 and connecting rods 14 and 15, respectively. The saucers 11 and 12 are designed to overlap with the saucer 8 in the middle, and the three saucers 8, 11 and 12 are respectively driven to the bumper 16 before painting which is transported by the hanger 5. The rail 2 and the trolleys 7, 9 and 10 are formed in such a size that foreign matter such as lubricating oil does not drop.

A sheet member 17 for adhering or absorbing foreign matter such as lubricating oil is removably laid on the trays 8, 11, 12 respectively.

The operation of the foreign matter adhesion prevention device for the overhead conveyor configured as described above will be described. As shown in FIG. 1, when the bumper 16 is transported in a horizontal and straight place where the drive chain rail 2 is horizontal, the drive chain rail 2 and the drive chain 3 that face the bumper 16 suspended from the hanger 5 are driven. , Three receiving trays 8, 11, 12 are arranged so as to block the guide rail 6, the trolleys 7, 9, 10 and the like from the bumper 16. Therefore, foreign matter such as lubricating oil falling from the drive chain rail 2, the drive chain 3, the guide rail 6, the trolleys 7, 9, 10 or the like adheres to the sheet member 17 laid on the trays 8, 11, 12 or It is absorbed and does not adhere to the bumper 16.

Further, as shown in FIG. 2, when the bumper 16 is conveyed through the inclined portion where the drive chain rail 2 is inclined, the front and rear trolleys 9 and 10 are connected to the middle trolley 7, respectively. Since they are flexibly connected by the rods 14 and 15, the three trays 8, 11 and 12 move so as to follow the inclinations of the drive chain rail 2, the drive chain 3 and the guide rail 6, respectively. Therefore, even in the inclined portion, foreign matters such as lubricating oil falling from the drive chain rail 2, the drive chain 3, the guide rail 6, the trolleys 7, 9, 10 and the like will be stored in the sheet member 17 laid on the trays 8, 11, 12. It is adhered or absorbed and does not adhere to the bumper 16.

Further, as shown in FIG. 3, even when the drive chain rail 2 is conveyed by the bumper 16 through the curved turning portion, the front and rear trolleys 9 and 10 respectively have the trolley 7 in the middle and the connecting rod 14. , 15 are flexibly connected, the three trays 8, 11, 12 move so as to follow the curved shapes of the drive chain rail 2, the drive chain 3, the guide rail 6, etc., respectively. Accordingly, foreign matter such as lubricating oil falling from the drive chain rail 2, the drive chain 3, the guide rail 6, the trolleys 7, 9, 10 and the like even in the swiveling portion is stored in the sheet member 17 laid on the trays 8, 11, 12. It is adhered or absorbed and does not adhere to the bumper 16.

[0016]

[Effect of device]

 As described above, according to the present invention, since the plurality of divided foreign matter trays are attached to the hanger support member, it is not necessary to make the tray larger than necessary, and each tray does not interfere with other production facilities. There is no. In addition, since a plurality of trays are arranged so as to block the drive chain rails, drive chains, guide rails, hanger support members, etc. facing the conveyed work even on the inclined part and the swivel part, a plurality of trays are arranged, so It is possible to reliably prevent foreign matter such as oil from adhering to the work. Further, by detachably attaching the sheet member to the receiving tray, foreign matter that has fallen onto the receiving tray can be easily removed, and the maintainability is improved.
