[0002]

2. Description of the Related Art A conventional dewatering device using compression is a two-stage system in which a dewatering device is formed by preliminary dewatering and then moved to another stage to perform main dewatering by pressurizing with a bellows. There is a one-stage method of pressure dehydration,
The outline and drawbacks of each are explained below. FIG. 1 is a schematic layout diagram of a conventional two-stage dehydrator, and FIG. 2 is a sectional view taken along line II-II in FIG. In the figure, reference numeral 1 is a continuous water washing machine, and a laundry 2 consisting of a fixed lot is intermittently introduced into a hollow housing 4 of a preliminary dewatering device 3. The housing 4 has a fixed cylinder 5 having a plurality of small holes for drainage on the outer circumference, and a rotary cylinder having a plurality of small holes on the outer circumference, which is rotated around a pin 6 by an air cylinder (not shown) to a position indicated by a two-dot chain line. It consists of 7. A pre-press air cylinder 8 is arranged above the housing 4, and a pressing plate 9 is attached to the tip of the piston rod 10 so that the pressing plate 9 can move up and down in the housing 4.

Reference numeral 11 denotes a conveyor belt, which is a preliminary dewatering device 3
A plurality of small holes for drainage are formed on the conveyor belt between the dehydrating devices 12. A bowl-shaped member 13 has an elastic film 15 such as a diaphragm that can cover the pre-dewatered laundry 14 attached to the opening edge. Reference numeral 16 is an air cylinder for raising and lowering, and the bowl-shaped member 13 is attached to the tip of a piston rod 17 so that it can be raised and lowered. 18 is a pressure chamber,
An elevating air cylinder 16 that communicates with a pressure liquid tank, a pump, and the like (not shown) and a hollow piston rod 17 that guides the same pressure liquid are communicated, and the elastic film 15 is always applied with negative pressure to the inner wall of the bowl-shaped member 13. And the elastic film 1 is applied to the surface of the laundry 14 by applying pressure during the main dehydration as shown in the figure.
Press 5. A discharge conveyor 19 conveys the laundry 20 after the main dehydration to a dryer (not shown). 21 is a drainage plate, which is arranged between the upper and lower belts of the conveyor belt 11,
It is fixed to a frame (not shown), and a drainage groove 22 is formed on the surface thereof. By the way, as the above-mentioned batch type dehydrator, for example, JP-A-50-50764
In this dehydrator, the laundry 2 from the continuous water washing machine 1 is received in the housing 4, and the preliminary press air cylinder 8 is operated,
By pressing down the pressing plate 9 and compressing the laundry 2, pre-dewatering is performed to form the cake.

Next, the rotary cylinder 7 is rotated to the position indicated by the chain double-dashed line, the conveyor belt 11 is conveyed in the direction of the arrow, and the cake is transferred to below the arm-shaped member 13 of the dehydrating apparatus 12. When the laundry 14 reaches under the bowl-shaped member 13, the conveyor belt 11 stops. Then, the bowl-shaped member 13 is lowered by the lifting air cylinder 16 to cover the laundry 14 on the conveyor belt 11, and a clamp (not shown) is used to form the bowl-shaped member 13.
The elastic film 15, the conveyor belt 11, the drain plate 21, etc. are clamped together. When the clamping is completed, the pressure liquid (usually water is used) is introduced into the pressurizing chamber 18 by a pressure liquid tank, a pump or the like (not shown), and the elastic film 15 starts descending to come into close contact with the laundry 14. . Further, the pressurized liquid is introduced into the pressurizing chamber 18, and the laundry 14 is pressed through the elastic film 15, so that the laundry 14 is dehydrated. When the laundry 14 is dehydrated, the clamp (not shown) is removed, the pressure liquid is discharged from the pressurizing chamber 18, the bowl-shaped member 13 and the elastic film 15 are raised, and the dehydrated laundry 20 is illustrated by the conveyor 19. Not transported to dryer.

Next, the one-stage dehydrator will be described with reference to the conventional dehydrator shown in FIG. 3. Reference numeral 23 is a main body base, which is installed on the work floor. 24 is a cylinder, the main body base 2
3, a cylinder portion is fixedly attached, and a conical part is fixedly attached to the piston rod. 25 is a dolly, to which wheels are attached via a cushion device. Reference numeral 26 denotes a cylinder jacket, which is a bottomless cylinder having a large number of small holes in the body. Reference numeral 27 is a general hydraulic cylinder fixed to a not-shown main body portion, 28 is a disk-shaped press plate fixed to a piston rod of the cylinder 27, 29 is an air cylinder attached to the not-shown main body portion, and 30 is a cylinder. A pin serving as a swinging fulcrum for supporting 29 on the main body (not shown), 31 is an air cylinder attached to the main body (not shown) and engaged with the cylinder 29, and 32 is a rocker for supporting the cylinder 31 on the main body (not shown).

1 is a hinge pin to be locked to 1, 34 is an air cylinder fixed to a main body (not shown), and 35 is clothes or the like to be dehydrated by laundry or an assembly thereof.

Now, referring to FIG. 3, the cylinder jacket 2
The trolley 25 carrying 6 and the laundry 35 is mounted on the main body base 23.
It is moved up and comes into contact with a stopper (not shown). Next, when the cylinder 24 is actuated and the conical portion fixed to the tip of the piston rod is lifted, the conical portion presses the lower surface circular cavity of the carriage 25 to position and fix the carriage. Then cylinder 2
When the press plate 28 descends from the state shown in FIG. 3 by operating 7, the carriage 25 is pressed through the laundry 35, and the cushion device of the carriage 25 bends and comes into contact with the upper surface of the main body base 23. At this time, the conical portion of the cylinder 24 also descends while being in pressure contact with the upper side. Then, the dehydration action proceeds in this step.

Next, the cylinder 31 is operated and the cylinder 2
After making 9 vertical, the cylinder 29 is actuated to engage the piston rod tip with the ear of the cylinder jacket 26. Further, by operating the cylinder 27 and moving the press plate 28 slightly upward, the relative displacement between the cylinder jacket 26 and the laundry 35 is facilitated. At this time, the contact between the upper surface of the main body base 23 and the lower surface of the carriage 25 is also released. Next, the cylinder 29 is operated to lift the cylinder jacket 26, which engages with the cylinder 29, so that its lower end is aligned with the press plate 28 or slightly above. Next, the cylinder 34 is operated to push the laundry 35 out of the machine and restore the cylinder later. Next, the cylinder 29 is operated to mount the cylinder jacket 26 on the carriage 25, and the engagement between the cylinder 29 and the cylinder jacket 26 is released later. Next, the cylinder 29 is operated to retract the piston rod, and the cylinder 31 is operated to restore the state of FIG. At the same time, the cylinder 27 is operated and the press plate 28 is pulled out above the cylinder jacket 26. Next, the laundry 35 is replaced with another truck (equivalent to 25) into which the laundry 35 has been loaded, and the above-described series of dehydration work is repeated.

[0008]

However, the conventional device of FIG. 1 has the following drawbacks. That is, the continuous type water washing machine 1 which is a pre-process of the dehydrator has a discharge port at a normally low position, and the opening of a dryer which is a post-process is generally provided at a high position. Therefore, as a dehydrating device, in order to facilitate communication with the dryer, the head is gradually covered through the discharge conveyor 19. However, when the discharge conveyor 19 is interposed, there is a problem that a predetermined space is required between the dehydrator and the dryer. Further, if the inclination angle of the conveyor belt 11 is too large, the pre-dewatered laundry 14 may be deformed while being conveyed from the pre-dewatering device 3 to the main dewatering device 12, and the main dewatering device 12 In this case, it may be impossible to completely cover the laundry 14 with the bowl-shaped member 13, and there is a drawback that the operation rate is lowered because the clamp is not applied and the laundry 14 is torn. Further, as the transport speed of the dehydration device, the conveyor belt, and the discharge conveyor to the dryer increases, the possibility of the above-mentioned shape deformation increases.
Further, even when the processing capacity of one lot is increased, there is a drawback that similarly becomes a problem. A control device such as a position detection device is provided to stop the laundry 14 at a predetermined position below the dewatering device 12.
Since the inertial force acts on the laundry 14 each time it is moved or stopped, accurate control is not sufficiently ensured. This problem becomes an additional problem when the transport speed or the processing capacity of one lot increases, and the apparatus is expensive because of the two-stage structure of preliminary dehydration and main dehydration.

Further, the dehydrator shown in FIG. 3 has the following drawbacks. That is, it is difficult to load laundry into the cylinder jacket at a uniform height, and even if the laundry with uneven thickness is squeezed between the top surface of the trolley and the bottom surface of the press plate, uniform dehydration can be achieved. Not only that, but also when strong pressing is required as a means for solving the partial lack of dehydration, there is a risk that the laundry will be broken by the load concentrated on the thick portion. Further, in the non-uniform dehydration state as described above, in order to achieve the purpose of drying in the dryer in the subsequent process, it is necessary to set the drying time in accordance with the portion with less dehydration, which wastes energy and further The parts were even overdried and could even damage the laundry. Further, the cylinder to which the press plate is fixed is generally a hydraulic drive system and has a large cylinder diameter for reasons such as obtaining a large squeezing force, which is uneconomical and
If the squeezing force is still insufficient, the hydraulic pressure is increased to use the oil, and the oil may leak and stain the laundry. The present invention has been proposed to overcome the above-mentioned conventional drawbacks.

[0010]

Therefore, the present invention is a continuous

Those are composed, it is an unit for which a problem solution.

[0011]

When the hydraulic cylinder operates in response to a signal indicating completion of loading from the continuous water washing machine, the membrane pressurizes the laundry, but when the pressure due to the pressurization and the hydraulic pressure are balanced, the membrane stands still in the pressurized state. Next, when the lifting device is activated after the pressure applied by the membrane is released by a timer or the like, the basket is raised and the laundry is moved and discharged by the conveyor.
