Reference numeral 8 denotes a pre-press air cylinder, which is disposed above the housing 31, and the pressing plate 9 attached to the tip of the piston rod 10 can move up and down in the housing 31. It has become. Reference numeral 13 denotes a bowl-shaped member, and an elastic film 15 such as a diaphragm capable of covering the pre-dehydrated laundry 14 is attached to the opening edge. 16 is an air cylinder for lifting and lowering,
The bowl-shaped member 13 is attached to the tip of the piston rod 17 and can be moved up and down. Reference numeral 18 denotes a pressurizing chamber, which communicates with a lifting / lowering air cylinder 16 that communicates with a pressure liquid tank (not shown), a pump, and the like, and a hollow piston rod 17 that guides the same pressure liquid. In addition to contacting the inner wall of the laundry 13, the elastic film 15 is relaxed at the time of main dehydration as shown in FIG. Reference numeral 19 denotes a discharge conveyor for conveying the laundry 20 after the main dehydration to a dryer (not shown). 3
Reference numeral 1 denotes a housing, which is composed of a fixed drum 32 and rotating drums 33 and 34, has a substantially cylindrical shape, and stores the laundry 2 from the continuous washing machine 1.

In FIG. 9, reference numeral 32 denotes a fixed body, which has a plurality of small holes for drainage on the outer periphery, and a plate 35 is integrally fixed by welding or the like. A rod 37 of an air cylinder 36 is connected to the plate 35. 33,3
Reference numeral 4 denotes a rotary drum, which has a plurality of small holes for drainage on the outer periphery, and plates 38 and 39 are integrally fixed by welding or the like. The rotating cylinders 33 and 34 are pivotally attached to the plate 35 by pins 40 and 41, and are rotatable by air cylinders 42 and 43 attached to the plate 35. Furthermore, arc-shaped push plates 44 and 45 are fixed to the ends of the plates 38 and 39 on the main dewatering device side, respectively.
0 is in contact with the outer peripheral portion. Reference numeral 46 denotes a slide table, which is installed between the preliminary dehydrator 3 and the main dehydrator 12.
The housing 31 can reciprocate on the slide table 46 between the dehydrating devices 3 and 12, and the slide table 46 has drain holes and grooves (not shown).

[0004] Next, the operation will be described. The laundry 2 from the continuous dehydrator 1 is housed in the housing 31, the prepress air cylinder 8 is operated to lower the pressing plate 9, and the laundry 2
Is preliminarily dehydrated to form a cake. At this time, as shown in FIG. 9, the rotating drums 33 and 34 are in the closed state, and the laundry 2 is formed into a cake shape. Next, the air cylinder 36 is operated to transfer the entire housing 31 to the main dewatering device 12 (FIG. 10). At this time, the housing 31 has been transported to just below the bowl-shaped member 13, and is pushed by the push plates 44 and 45.
The dewatered laundry 20 has been pushed out onto the carry-out conveyor 19. Next, the air cylinders 42 and 43 are operated to rotate the rotating drums 33 and 34 to bring them into the open state in FIG.

If the inclination angle of the slide table 46 is set to be large corresponding to the opening of the dryer, it is necessary to provide a discharge conveyor between the dehydrator and the dryer. Disappears,
Effective use of space and reduction of parts.

As described above, in the conventional example, since the laundry is stored in the housing and transported from the preliminary dewatering device to the main dewatering device, the risk of deformation during the transport is completely eliminated, and the bowl-shaped member is removed. , And there are no problems such as a decrease in the machine operation rate and a break in the laundry caused by the inoperative clamp. Further, even if the transport speed or the capacity of one lot is increased, since it is housed in the housing and transported, the possibility of shape deformation is completely eliminated. Further, since the transfer is performed by the air cylinder, the influence of the inertial force is smaller than that of the conveyor belt, and the housing can be accurately controlled. On the other hand, by adopting the housing transfer system instead of the conveyor belt, large power is not required, stable conveyance is possible, and rotating members such as conveyor belts, rollers, and motors are not required, and durability is improved. It has excellent effects.

[0006]

By the way, recently, there are a wide variety of types of laundry to be processed by a continuous washing machine, and in particular, there is an affinity for water such as dust control mats, sheets having a high tetron content, and sauna pants. After spin-drying with a preliminary dehydrator as in the prior art, open the rotating drum and place the laundry on the slide, the pile of the laundry collapses, and the pile of the laundry collapses. There is a problem that the laundry protrudes from the pressing surface of the pressing member of the dewatering press. At this time, manually correcting the pile of laundry involves danger. In addition, the problem caused by repositioning the laundry is not a problem in a normal single-stage dehydrator, but the following problem occurs in a device that performs high-pressure dehydration without damaging the laundry. In other words, in high-pressure dehydration, the pressure is maintained for a short period of time at the beginning of dehydration,
Then you have to take the method of gradually increasing the pressure. Therefore, if the laundry is replaced, the cycle time for dehydration becomes longer and the processing capacity must be reduced.

Therefore, the present invention places at least two cylindrical baskets for storing laundry in a symmetrical manner,
A horizontal rotating disk which can be operated intermittently and has a large number of drain holes on its surface, a driving device for this disk, and a cylindrical basket with the laundry left on the rotating disk on the main press side. A clamp mechanism that grasps and raises and lowers while taking out, a delivery device that sends laundry to the next process, and a mechanism that raises and lowers the device after the device returns to its original position (horizontal) The present dewatering machine proposes that the laundry dehydrated by the pre-pressing part as the pre-dewatering device can be dewatered in the main pressing part as the main dewatering device while being dewatered in the pre-pressing part. Thus, the above-mentioned conventional problems are to be solved.

[0009]

The laundry is put into a cylindrical basket placed on a rotating disk at the pre-press position, where it is compressed and dewatered by low pressure. After the completion of the preliminary press, the pressing plate is raised, and the rotating disk is rotated by 180 °. The basket containing the laundry also rotates with the rotating disk, and stops at a position below the main press that has been rotated by 180 °. Simultaneously another symmetrically placed empty cylindrical basket moves under the pre-press and stops, the press with water-filled membrane of this press descends and dehydrates the laundry in the cylindrical basket at high pressure . Next, the pressing body of the main press slightly rises to release the pressure of the laundry, and then, while the laundry is placed on the rotating disk, only the cylindrical basket is gripped by the centering clamp and rises. The laundry left on the rotating disk is sent out to the next process from the rotating disk by the sending device. After the sending device returns to its original state, the entire device rises. The cylindrical basket then descends on the rotating disk, releasing the basket from the clamp. Thereafter, the clamp is raised, the pressing body of the main press is also raised, and the rotating disk rotates again by 180 ° to move the basket under the preliminary press. At this time, the next basket containing the laundry dehydrated by the low pressure in the preliminary press moves under the main press, and the same process is repeated thereafter.
