Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for successively transporting and immersing parts to be cleaned from one cleaning tank to the next cleaning tank in order to remove adhered oil and the like.

[0002]

2. Description of the Related Art Conventionally, in a cleaning tank, parts to be cleaned are usually transported by a chain block. For this reason, the transfer took time and was inefficient.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a more efficient transfer device in a cleaning tank.

[0004]

[Means for Solving the Problems] A trolley is run on a plurality of cleaning tanks arranged at regular intervals. The trolley moves back and forth by the same distance as the cleaning tank. The trolley will be provided with a lifting platform that can move up and down horizontally. A hanger for simultaneously lifting multiple washing baskets is attached to this lift. Hanger
Install at the same intervals as the cleaning tanks.

The lifting platform is supported by a carriage via an X-shaped link whose center is connected by a pin, and the X-shaped link is opened and closed by a cylinder to move the lifting platform up and down.

[0006]

[Operation] The trolley lifts the washing basket, moves forward by the same distance as the distance between the washing baths, and suspends the washing basket in the washing bath. Then, the trolley moves backward, the washing basket is lifted again, the trolley moves forward by one interval, and is hung on the washing tank. Thus
A plurality of cleaning baskets are sequentially transferred from the cleaning tank to the cleaning tank.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. A plurality of cleaning tanks 11, that is, first to fifth tanks are arranged in a line at regular intervals from the right in FIG. The tank is filled with rinsing water). The mechanical parts to be cleaned are placed in the cleaning basket 13 and immersed in these baths.

A pedestal 15 is provided in front of the first tank at the same interval as that of the cleaning tank. After the fifth tank, a belt conveyer 17 for unloading the washed basket is arranged.

As shown in FIG. 3, the cleaning basket 13 is provided with a horizontal bar 19, which is supported by the edge or the pedestal 15 of each cleaning tank 11. Reference numeral 21 is a guide piece for positioning the horizontal bar 19.

Further, in the cleaning basket 13, a pair of inverted L-shaped members 23 for lifting are mounted on the horizontal bar 19 so as to face each other. The horizontal portion of the inverted L-shaped member 23 has a mountain-shaped cross section, and a hanger (which also has a mountain-shaped cross section) 45 described later is engaged so as to be picked up from below.

A pair of left and right rails 27 are laid on a frame 25 assembled around the cleaning tank 11, and a carriage 29 is placed on the rails 27. Reference numeral 31 is a wheel, which is six in total. Trolley 2
9 is a telescopic cylinder (electric) 33 so that it can move between two states, a rear position (solid line in FIG. 1) and a front position (chain line in FIG. 1).
To provide. The cylinder end is supported on the frame side and the rod end is supported on the truck side. The amount of expansion and contraction of the cylinder 33, and hence the moving distance of the carriage, is set to be equal to the distance between adjacent cleaning tanks.

The dolly 29 is provided with two lifts 35, and each lift is a telescopic arm 37 extending downward from the dolly.
Support before. The telescopic arm 37 is formed by connecting two X links 41 whose center is rotatably connected by a pin 39, and one end (left side in FIG. 1) of the lower X link is pivotally attached to the lift table 35, and the other. The end is supported on a lift so that it can slide horizontally. Further, one end (left side in FIG. 1) of the upper X-link is pivotally attached to the carriage 29, and the other end is supported so as to be horizontally slidable on the carriage. A telescopic cylinder (electric) 43 is attached between the slide end and the trolley, and the cylinder 4
When 3 is contracted, the X-shaped link is narrowed to extend the arm 37, and when the cylinder is extended, the X-shaped link is opened and the arm is contracted, and accordingly, the elevating table 35 moves up and down while being horizontal.
Note that, in FIG. 1, a state in which the right expandable arm is contracted is shown by a chain line.

As described above, each lifting table 35 has
A hanger 45 for lifting the cleaning basket 13 is fixed. There are a total of 6 hangers, 3 for each lift, and are arranged at the same intervals as the cleaning tank 11.

This device operates under sequence control, and its operation will be described below. In the state shown by the solid line in FIG. 1, the carriage 29 is at the rear position, the telescopic arm 37 is extended, and the lift table 35 is lowered. The first hanger (rightmost in FIG. 1) is located directly above the pedestal 15, and the second to sixth hangers are immediately above the first to fifth tanks, respectively. Further, the cleaning basket 13 is immersed in all the cleaning tanks 11, and the cleaning basket 13 containing the mechanical parts to be cleaned next is placed on the pedestal 15.

In this state, when a predetermined immersion time, for example, 2 minutes, elapses, the cylinder 43 extends, the X-shaped link 41 opens, and the two lifts 35 rise together. Then, the hanger 45 engages with the inverted L-shaped member 23, and each washing basket 13
(That is, the cleaning basket on the pedestal and the cleaning baskets immersed in the first to fifth tanks) are lifted.

Then, this time, the cylinder 33 extends and the carriage 29 advances to the front position (the position indicated by the chain line in FIG. 1). Cylinder 33
In this state (front position), the six washing baskets 13 that have been lifted are
~ Comes directly above the fifth tank and the belt conveyor 17, respectively. Next, the cylinder 43 contracts, the X-shaped link 41 narrows, and the lift table 35 descends. As a result, the cleaning baskets lifted by the first to fifth hangers are immersed in the corresponding cleaning tank 11, and the cleaning baskets lifted by the sixth hanger are placed on the belt conveyor 17. The washing basket placed on the belt conveyor is blown with air to cut off the drops and sent to the drying room. At the same time, a new washing basket is supplied on the pedestal 15.

Thus, again after a certain immersion time,
The trolley 29 moves backward to the rear position, the washing basket on the pedestal 15 and the washing basket immersed in each of the first to fifth tanks are lifted again, and the carriage 29 is advanced to the front position to hang the washing basket. In this way, the cleaning basket 13 is attached to the cradle 1
From the 5th to the 1st, 2nd, ... 5th cleaning tank, they are successively conveyed and dipped to remove oil stains, and then sent out to the next step by the belt conveyor 17.

[0018]

As described above, the device of the present invention is
On a plurality of cleaning tanks lined up at regular intervals, a bogie that moves back and forth by the same distance as the interval of the cleaning tank, and is supported by a bogie,
It consists of an elevating table that moves up and down while maintaining horizontal level, and multiple hangers that are attached to the elevating table at the same intervals as the cleaning tank to lift the cleaning basket. Simultaneously cleaning multiple cleaning baskets from the cleaning tank. Can be forwarded to the tank and has excellent transport efficiency.

In particular, since the trolley moves a short distance (only the same distance as the distance between the cleaning tanks), the apparatus can be downsized,
The drive unit can also be a simple one such as a telescopic cylinder. In addition, since the washing basket is lifted by the elevating table that maintains the horizontal position, the washing basket is less likely to shake and the parts to be cleaned inside are less likely to be damaged.

If the lifting platform is supported on the carriage via an X-shaped link whose center is connected by a pin and a cylinder for opening and closing the X-shaped link is attached, the structure can be simplified and the operation is reliable.
