Description

[Detailed Description of the Invention] (Industrial Application Field) The industrial application field of the present invention is cleaning mops, mats, etc.
In the field of dehydration equipment used after washing equipment such as drum-type washing machines for dyeing.

(Prior Art) When motsus and mats used in large quantities become soiled and collected, they must be washed, dyed, dehydrated, and dried in order to be reused.

Conventionally, a drum-type cleaning device has been used to wash motsus and mats in large quantities. + and staining were performed, followed by dehydration.

(Problem to be solved by the invention) However, when attempting to dehydrate, there are piles of mops, mats, etc. that are sent out at one time from the washing device.
Moreover, since each motupu or mat contains a large amount of water, the piles tend to collapse and spread quickly, and even if you try to dehydrate them by pressing them, you cannot dehydrate them evenly. there were.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention receives the mops and mats sent out from the cleaning device in a packet, sends the packets to a dehydration position, and at the same time as the packets are drained, the fork basket is raised, and the mops and mats are raised. Surround the mountain with fork baskets to prevent the mountain from collapsing, and in this state lower the dewatering device and lower it together with the fork basket to the dewatering position, and perform dewatering without the mountain collapsing. It was configured so that it can be done.

[Effect]

If such a structure is adopted, the mop or mat containing a large amount of water can be dehydrated without collapsing, and the whole can be dehydrated uniformly.

There is drying in the latter stage of this belt conveyor 14! 178 is disposed, and this dryer 78 is rotatably supported via a shaft 19, and by rotating clockwise around this shaft 79 in the clockwise direction in FIG. Can be discharged on top.

Next, the operation of the apparatus of the present invention configured as described above will be explained.

The cleaning material discharged from the cleaning device 1 is thrown into a packet 2) via a hopper 81. This cleaning object is designated by the reference numeral 82 in FIG.

Then, just before preliminary dehydration is carried out, Fig. 7 (A)
As shown in FIG. 3, the cylinder 38 is operated and the bracket 40 is held between the forks 39.

In this state, as shown in FIG. 7(B), the press plate 45 descends into the packet 2) via the cylinder 47, and presses the cleaning object 82 with a predetermined pressure to perform preliminary dehydration.

At this time, the opening/closing frames 2)b and 2)b are locked and will not open even if a large pressure is applied.

When the preliminary dehydration is completed, the lock of the packet 2) by the cylinder 38 is released and the press plate 4 is released as shown in FIG. 7(C).
5 will also rise.

Subsequently, the motor 35 is activated, the chain 33 is run, and the packet 2) is moved toward the main dewatering device 19.

Since there is a dehydrated material 82a which has already been fully dehydrated on the frame 20 below the frame 52 of the main dewatering device 19, the packet 2) pushes this out toward the belt conveyor 74.

Then, after a short period of time has passed after the proximity switch 41 stops the cylinder 28 at a predetermined position, the cylinder 28 is moved under the frame 52.
is activated, and the opening/closing frame 2)b opens as shown in FIG. 7(E).

At this time, the dehydrated material 82a is on the belt conveyor 74, lifted up by the winch 77, and in the process of being thrown into the dryer 78 side.

When the opening/closing frames 2)b and 2)b open, the motor 35 reverses and returns to its original position, leaving the preliminary dehydrated material 82 (Fig. 7 (
F)).

Almost simultaneously with the return operation of the packet 2), the cylinder 65 is actuated and the fork basket 70 starts to rise, and the returned packet 2) is locked again by the cylinder 38.

This state is shown in FIG. 7(G).

As shown in FIG. 7(H), when the fork basket 70 rises and surrounds the pre-dehydrated material 82 to prevent the pre-dehydrated material 82 from collapsing, the fork basket 70 is raised upward as shown in FIG. 7(I). The frame body 52 descends and begins to push the tip of the fork basket 70 with its lower end. The fork basket 10 is lowered together with the frame 52, and the preliminary dehydrated material 82 is accommodated within the frame 52.

When the proximity switch 63 detects that the frame body 52 is in contact with the frame 20, the cylinder 55 is actuated, and the wedge plate 56 moves forward and is pushed into the lower surface of the cam 60.

Then, the frame body 52 is completely fixed on the frame 20 due to the wedge effect of the wedge plate 56.

This state is shown in FIGS. 7(J) and (K).

When the frame body 52 is completely fixed, the frame body 5
Water at a predetermined pressure is supplied between the upper bottom of 2 and the rubber plate 57, and as shown in FIG. 6, the pre-dehydrated material 82 is pressed through the rubber plate 57 to perform water pressure dehydration.

When the main dehydration is completed, the water pressure is removed and the water pressure is removed, as shown in Figure 7 (
As shown in L), the wedge Rfi 56 returns to its original position and the frame 52
As shown in FIG. 7(M), the dehydrated product 82a is placed in the frame 2.
Leave it above 0 and rise.

As in No. 1 above, dehydration is performed sequentially with the steps shown in FIGS. 7(A) to M) as one cycle.

FIG. 8 shows a simple flowchart of the above-mentioned operation.

By the above-described operation, uniform dehydration can be performed without the object to be dehydrated collapsing.

〔effect〕

As is clear from the above description, according to the present invention, an object to be dehydrated that has been pre-dehydrated is held by a fork basket so as not to collapse, and the fork basket is lowered in conjunction with the lowering of the frame. The object to be dehydrated can be held without collapsing until immediately before hydraulic dehydration, and the object to be dehydrated can be uniformly dehydrated.
