Abstract

PURPOSE:To provide a hanging conveyer apparatus of an automatic car assembly process, which can convey plural works by disposing a plurality of receiving means on both sides of a rail guide mover in such a manner as to be freely selected to an operation position and to a non-operation position. CONSTITUTION:A mover 2 is moved on a rail 1 by a driving device 9. Hanger frames 20, 30 are pivoted on shafts 15, 16 by cylinders 48, 49, so that the frames are brought close to or separated from each other to load and unload a work 5. At this time, according to the shape and size of a work 50 to be handled, receiving means 28A, 29C, 38A, 39C of respective fixing frames 24, 25, 34, 35 are manually adjusted so that the optimum receiving means acts upon the work 50. Thus, plural kinds of works can be handled, and the storage line can be shortened.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a suspended conveyance device employed for supporting and conveying side panels, underbodies, etc., for example in an automobile assembly line.

Conventional technology Conventionally, as a suspension conveyance device for this scale, a moving body supported and guided by rails is provided, a hanger frame that can swing left and right is provided on both sides of this moving body, and multiple points on these hanger frames are installed. A configuration with an integrated receiver is provided.

By moving the hanger frame left and right, the receiver is moved between the active position and the non-active position, thereby engaging and disengaging the object to be transported.

Problems to be Solved by the Invention According to the above-mentioned conventional configuration, since each moving body has a fixed support form, only one type of object can be transported, and therefore, multiple types of objects can be transported on the same transport line. When transporting, different types of moving objects are required depending on the number of types.
Not only is the entire membrane width expensive, but storage lines for unused portions must be provided well.

Means for Solving the Problems In order to solve the above-mentioned problems, the hanging conveyance device of the present invention includes a moving body that is supported and guided by rails, and a hanger frame that is swingable from side to side on both sides of this moving body. Attachment frames are provided at a plurality of locations on these hanger frames, and these attachment frames are provided with a plurality of receivers that can be freely switched between an active position and a non-active position, respectively.

Effects According to the configuration of the present invention described above, it is possible to lock and unload the conveyed object by swinging the hanger frame left and right, but the locking position is determined depending on each installation.
This can be changed arbitrarily by switching at least one of the plurality of receivers to the working position and the rest to the non-working position.

EXAMPLE An example of the present invention will be described below based on the drawings. 1
is a rail having an r-shaped cross section, and a moving body 2 supported and guided by this rail 1 is provided. That is, the movable body 2 includes a main body 3 that is rectangular in plan view and has a frame plate shape, brackets 4.5 connected upward from the upper surface of the front and rear ends of the main body 3, and the rails that are attached to these brackets 4.5. # on the top of 1
& denotes freely movable wheels 6, 7, a lateral vibration prevention roller 8 that is attached to one bracket 4 and can come into contact with both sides of the lower end of the rail 1, and n wheel bodies 6 that are attached to one bracket 4.
It is configured to be self-propelled by a drive device 9 that is interlocked with.

Note that the movable body 2 may be of a type that travels by receiving other power, such as a driving chino. Rollers 10 are mounted on both sides of the upper surface of the main body 3 and at the center in the longitudinal direction, and steady rest rails 11 that can freely approach and move away from the rollers 10 from above are provided at appropriate locations. The mobile body 2
Hand frames 20 and 30 are provided on both sides of the handle frame 20 and 30, which are swingable from side to side. In other words, the hanger frames 20.30 each include a pair of vertical rods 21.22.31.32 and horizontal rods 23.33 that connect the vertical rods 21.22.31.32 that face each other in the front and rear. and each vertical rod 21
．． 22. The upper ends of 31 and 32 are attached to the main body 3 with bearings 13.14
It is fixed to a rotation axis 15, 16 in the longitudinal direction supported through the.

A box-shaped mounting frame 24.25.34.35 is fixed to the lower end of each vertical rod 21.22.31.32.
．． The longitudinal bins 26, 27, 36, 37 along 16 are the attachments.

Each of the longitudinal bins 26, 27, 36, 37 has a plurality of (three in the embodiment) receivers 28A, 28B,
28C.

29A, 29B, 29C, 38A, 38B, 3
8C, 39A.

39F3 and 39C are attached, and these have two positions: a non-operating position in which they are swung upright around the axis of the bottle, and an operative position in which they are swung horizontally and received by the stopper plate 30.31.40.41. It is configured such that it can be freely switched between the two. Brackets 42.inwardly from said axis of rotation 15.16.
43 are installed in series. At the loading/unloading area, cylinder devices 48, 49, which are operated by handles facing the brackets 42, 43 from above, are provided. Reference numeral 50 indicates a side panel which is an example of an object to be transported, and reference numeral 51 indicates a positioning guide.

The relocated body 2 is supported and guided by the rails 1 by the operation of the drive device 9 and travels on a fixed path. Then, at the loading and unloading location, the roller 10 is guided by the anti-photograph rail 11, so that it is rested and stopped. Then, the hanger frames 20, 30 are swung toward or away from each other around the axis of rotation Is, +6 by the operation of the cylinder devices 48, 49, thereby loading and unloading the side panels 50. Before stacking, the receivers 2 are installed according to the shape and size of the side panels 50 to be stacked.
8A, 28B.

28G, 29A, 29B, 29C138A, 38
B, 38C139A, 39B, 39C are manually adjusted. That is, for each installation, at least one receiver optimal for receiving the side panel 50 is swung horizontally in the frame 24, 25, 34, 35, and the stopper plate 30 is
．． 31. Bring it into contact with 41 at 40° to set it to the working position. The remaining receivers are then swung into an upright position to a non-operating position.

Thereafter, the side panels 50 are supplied, and the hanger frames 20, 30 are opened and stacked.

Effects of the Invention According to the hanging conveyance device of the present invention having the above-mentioned configuration, by swinging the hanger frame left and right, it is possible to engage and disengage the object to be conveyed. In this case, the locking position can be arbitrarily changed by placing at least fourteen of the plurality of receivers in the working position and switching the rest to the non-working position in each mounting frame. Therefore, it is possible to transport a plurality of types of objects on the same transport line using a common moving body, which makes it possible to reduce the cost of the entire equipment and to shorten the length of the storage line.
