Description

Description: TECHNICAL FIELD The present invention relates to a hanger transfer device in a surface treatment device capable of preventing a workpiece to be hung from a hanger from swinging.

(Prior Art) The hanger transfer device in the conventional surface treatment device is the sixth one.
As shown in the figure, the hanger (53) of the rack (52) holding the object to be processed (51) is engaged with the hanger support rod (54) of the lift truck (55) that moves up and down on the lift guide (56) to move up and down. In the conventional type, the rack (52) holding the object to be processed (51) is lifted above the processing tank by raising the carriage (55) and then moved horizontally. Therefore, as shown in FIG. 6, when the raising / lowering guide (56) is moved and stopped at a predetermined position, the object to be treated (51) is apt to shake, and when it is lowered as it is, the object to be treated (51) is treated ( 57) Partition plate (57
The hanger (53) that is in contact with a) and suspends the object to be processed (51) is disengaged from the hanger support rod (54) to be processed (5).
There was a problem that 1) might fall.

(Problems to be Solved by the Invention) The present invention solves the conventional problems as described above, and the hanger holding the workpiece swings even when the lifting guide is moved and stopped at a predetermined position. It was completed for the purpose of a hanger transfer device in a surface treatment device that does not have any.

(Means for Solving Problems) According to the present invention, a lifting carriage mounted on a lifting guide that moves above a processing tank so as to be lifted is provided with a hook portion of a hanger and a hanger support rod that can be engaged and disengaged, and the lifting carriage is lifted. A pair of L-shaped holding levers having a lower end for holding the hanger are pivotally supported on a bearing frame provided near the stop position so that the upper arms of the holding levers cross above the hanger support rod. It is a thing.

(Embodiment) Next, an embodiment of the present invention will be described in detail with reference to FIGS.

(1) is an elevating guide that can move on the treatment tank (2), and the elevating guide (1) is the lower end of a carrier vehicle (4) traveling on a traveling rail (3) installed above the treatment tank (2). It was installed vertically. Reference numeral (5) is a lift truck that moves up and down along a lift guide (1), and an object to be processed (7) is provided on both sides of a support arm (6) provided at a lower front portion of the lift truck (5).
Hanger support bar (6) that can be engaged and disengaged with the hooks (9a) and (9b) of the hanger (9) that suspends the rack (8) holding the
a) is provided.

(10) is an anti-sway device provided in the lifting guide (1) near the lifting stop position of the lifting carriage (5). The anti-sway device (10) is an arm rod (1
1) A pair of bearing frames (12) hung vertically, and (12) a pair of L
Insert the holding levers (16), (16) in the shape of a letter into the shaft pins (13), (1
It is rotatably supported by 3). These clamping levers (16), (16) have lower ends thereof as a clamping part of the hanger (9), and the upper arms (14), (14) of the clamping levers (16) above the hanger support rod (6a). It is pivotally supported so as to cross. The holding levers (16) and (16) are normally provided with the upper arm (1) as shown by the chain line in FIGS. 1 and 5.
4) and (14) are expanded from the shaft pin (13) as a starting point in a state in which the front side hangs downward due to its own weight, but the front side of the upper arms (14) and (14) Lift truck (5)
If the upper surface of the hanger support rod (6a) that has been lifted up is pushed up, conversely to the above, the clamping levers (16) and (16) are closed from the shaft pin (13) as the starting point, and the clamping part formed at the lower end ( 16a) and (16b) sandwich the hanger bar (9b) of the hanger (9) suspended from the hanger support rod (6a) from the front and rear. (17), (17) are bearing frames (12),
A stopper rod provided at a lower position on the outside of (12),
By restricting the expansion of the holding levers (16) and (16), the tips of the upper arms (14) and (14) are located at the ends of the hanger support rod (6).
It is to prevent it from coming off the upper position of a). If the weight of the upper arms (14) and (14) is such that they cannot hang downwards due to their own weight, even if the clamping levers (16) and (16) are expanded using a spring, Needless to say, the bearing frames (12) and (12) are directly attached to the carrier truck when the lift guide (1) is vertically installed at the lower end of the carrier truck (4) as in this embodiment. It may be suspended from the lower end of the.

(Operation) In the structure thus configured, the hook (9a) of the hanger (9) of the rack (8) is engaged with the hanger support rod (6a) to raise the workpiece (7) and When the elevating guide (1) is moved over the processing tank (2) and reaches a predetermined processing tank (1), the elevating guide (1) is stopped and the elevating carriage (5) is moved along the elevating guide (1). It is the same as the conventional hanger transfer device in this kind of surface treatment apparatus that the object to be treated (7) is immersed in the treatment tank (2) by lowering it. However, according to the present invention, since the rocking stop device (10) is provided in the vicinity of the ascending / descending position of the lift truck (5), the object to be processed (7) is conveyed to a predetermined processing tank (2). In this case, if the hanger (9) is lifted, the upper surface of the hanger support rod (6a) of the lift truck (5) will be the bearing frame (12),
A pair of holding levers (16) pivotally supported between the bearing plates (12a) and (12a) of (12) are brought into contact with the crossing portions of the upper arms (14) and (14) of the (16), and the upper arms (14). 14), push up on the other side of (14). This allows a pair of clamping levers (16), (16)
Is closed, and the holding portion (16a) at the lower end thereof holds the hanger bar (9b) of the hanger (9). This prevents the hanger (9) from swinging, so that the object (7) to be contacted with the partition plate (2a) of the processing tank (2) when the hanger (9) descends and the hook portion (9a) of the hanger (9) is hangered. There is no risk of falling off the support rod (6a). Moreover, when descending, the upper arm (14) by the hanger support rod (6a),
The upward pressure of (14) is released, and the tips of the upper arms (14) and (14) are returned to the lower position, and the clamping levers (16) and (16) are fully expanded to support the hanger. It does not hinder the descent of the rod (6a).

(Effects of the Invention) As is apparent from the above description, the present invention oscillates a hanger that suspends an object to be processed without raising or lowering the hanger when the hanger is lifted to a transfer position by a lifting carriage. Therefore, when the object to be processed is raised and conveyed in the horizontal direction, it does not shake or the hanger does not come off. Therefore, the present invention is extremely significant in that it contributes to the development of the industry by solving the problems of the conventional hanger transfer device in this type of surface treatment device.
