DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifugal dehydrator used in a laundry factory or the like.

[0002]

2. Description of the Related Art Among the above-mentioned conventional centrifugal dehydrators, a centrifugal dehydrator of a type that rotates at a high speed along a vertical plane by a horizontal axis, a dewatering basket fixed to a rotary frame is placed on both sides of one diameter of the rotary frame. Were provided one by one to balance and spin at high speed to dehydrate.

Moreover, in such a device, it is difficult to store the laundry in the dewatering basket fixed to the rotating frame, and the device is rotated by the slight difference in the weight of the laundry stored in the dewatering baskets on both sides. The movement of the rotating frame inside becomes large, and it is difficult to balance the weight.

[0004] In addition, since there are only two dewatering baskets in one dehydration operation, when used in a continuous washing machine, the flow rate is restricted as a whole. For this reason, in order to maintain the flow speed, the time for one dehydration is about 7 minutes, so that the laundry to be transferred to the next drying step has a high moisture content, and the drying time is long. Speed restrictions will occur.

[0005] Further, if the dewatering basket is made large in order to increase the amount of dehydration processing at one time, the direction of the laundry in the dewatering basket is greatly affected, causing large vibration during operation.

In order to solve these problems, the applicant of the present application has proposed a centrifugal dewatering machine having a dewatering basket which can be divided into three parts and inserted and removed, as disclosed in Japanese Utility Model Application No. 1-119384. FIG. 4 (side view), FIG. 5 (front view)
As shown in (1), the laundry is transferred from the washing process by the carry-in conveyor 1 and put into the hopper 2. On the other hand, among the dewatering baskets 6 equally inserted into the rotating frame 7 at 120 ° intervals as shown in FIG. 5, the dewatering basket 6 inserted at the dewatering basket insertion position stopped at the lower position of the rotating frame 7 is a hopper. 2, the bottom plate 2 a of the hopper 2 is opened, and the laundry falls into the dewatering basket 6.

Next, the dewatering basket 6 containing the laundry is inserted by an insertion device (not shown) while being slightly lifted to the dewatering basket insertion position stopped at the lower position of the rotating frame 7.

This operation is repeated three times to uniformly insert the laundry into the dewatering baskets 6 in the rotating frame 7, and the entrance lid 11 of the insertion opening is raised to close the entrance of the frame 10. At this time, it goes without saying that the outlet lid 12 of the discharge port is closed.

In this state, the rotating frame 7 held by the horizontal shaft 5 is rotated at high speed by a motor (not shown) via the pulley 8 and the belt 9 to dehydrate the laundry by centrifugal force. In this case, it is almost impossible to completely and completely store the laundry, and the rotating frame 7 always vibrates.
This vibration is configured to be absorbed by the air damper 4.

After the high-speed rotation for a predetermined time, the outlet lid 12
Is opened, the dewatering basket 6 stopped at the upper position of the rotating frame 7 is pushed out from the discharge port in an upside down state, and the dewatering basket 6 at the reverse position is held by a holding device (not shown) and carried out to the next drying step. The laundry is dropped on the conveyor 3.

The above dewatering basket 6 is shown in FIG.
(B) As shown in the side view and the sectional view of FIG. 3, the cylindrical bottom surface of the lower surface is made of punched metal having the same curved surface as the inner surface of the outer periphery 7a of the rotating frame 7, and both side surfaces (the left and right side surfaces shown in (a), The supporting members 13 are attached to the front side (b) as shown in FIG.

Further, a jetty 6a for preventing the laundry from moving in the lateral direction is provided at two places inside the cylindrical bottom surface.

The supporting member 13 has a single sliding plate 13a which is bent over the entire width thereof and has an upwardly-curved cross section.
And a reinforcing plate 13b provided perpendicularly to the side surface at a plurality of positions between both ends and an intermediate portion of the sliding plate 13a. Further, the reinforcing plate 13b has a lower half separated from the side surface,
The separated portion forms an insertion space 14 into which an external fork for lifting the dewatering basket 6 is inserted.

[0014]

However, the above dewatering basket 6 is turned upside down after dewatering by a jetty 6a provided so as not to lose the overall balance due to lateral movement during the dewatering operation. When the laundry is pushed out from the outlet in the state, the laundry after dehydration may stick to the cylindrical bottom surface and the jetty 6a and may not fall naturally.

An object of the present invention is to solve the above-mentioned problem and to provide an apparatus for completely dropping the dehydrated laundry from the dewatering basket 6 pushed out from the discharge port onto the carry-out conveyor 3. .

[0016]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, there is provided a dewatering device which is inserted into a partition wall 7b of a high-speed rotating frame 7 for use in a dewatering process provided between a washing process and a drying process. Centrifugal dehydration in which the basket 6 is inserted into the partition wall 7b stopped at the lowermost end in an upward direction from the insertion port, and is discharged from the partition wall 7b stopped in the uppermost position in a downward state from the discharge port opposite to the insertion port. In the machine, a peeling device is provided outside the discharge port. The peeling device is provided on both outer sides of the discharge port, and carries a support member 13 on both side surfaces of the dewatering basket 6 and carries out the same. A push-down device 17 for pushing down the laundry from the dewatering basket 6 in the downward state stopped at the end position;
Is provided with a push rod 17a which projects into the dewatering basket 6 through a through hole formed in the bottom surface of the dewatering basket 6.

[0017]

As described above, the dewatering basket 6 is in a downward state when pushed out of the rotary frame 7, but the wet laundry after dehydration is subjected to centrifugal force on the bottom surface of the punch metal of the dewatering basket 6 and the jetty 6a. It is hard to fall down as it is because it is stuck on. For this reason, the laundry is reliably dropped by projecting the pushing rod 17a from above into the dewatering basket 6 from the pushing-down device 17 in synchronization with the movement of the dewatering basket 6.

[0018]
