DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a dehydrator for dehydrating clothes after washing by pressing.

(Prior Art) FIG. 6 is a side view of a conventional dehydrator for laundry and the like, and FIGS. 7 and 8 are sectional views for explaining the operation of the dehydrator of FIG. 6, respectively.

In FIGS. 6 to 8, 35 is a pedestal installed on the work floor surface, and 36 is an upper pedestal fixed to the pedestal 35 and the pillars 37. The pillars 37 are constituent members that connect the gantry 35 and the upper gantry 36, and a plurality of pillars 37 are arranged. 38 is a deck that is a lattice member fixed to the gantry 35, 39 is a deck plate that is a perforated plate that is fixed to the deck 38, 40 is a perforated or mesh wide conveyor belt that can pass water, 41 Is a roll that drives the transporting conveyor belt 40.

42 is a basket formed in a cylindrical shape, 43 is an input port which is an opening formed in the upper portion of the basket, 44 is a guide fixed to the basket 42 and engaged with the pillar 37, and 46 is fixed to the upper mount 36. Drive device for engaging the basket 42 with a chain or the like, 47 is a hydraulic cylinder fixed to the upper frame 36, 48 is a hydraulic device including an oil tank and a hydraulic circuit for the hydraulic cylinder 47, and 49 is a hydraulic device 48. Hydraulic pump,
50 is a drive motor for the pump 49, 51 is a piston rod of the cylinder 47, 52 is a press plate fixed to the piston rod 51,
Reference numeral 53 is a pressurizing member which is an elastic film that closely adheres the press plate 52 to the opening to enclose water, 54 is a water supply port attached to the press plate 52, and 55
Is an air vent installed in the press plate 52, 56 is an enclosed liquid enclosed between the press plate 52 and the pressurizing body 53, and 57 is a guide, which is attached to a groove on the side surface of the press plate 52, Plate 52,
The basket 42 serves to prevent contact. 58 is a continuous water washing machine that is placed before the dehydration process, 59 is a discharge conveyor that is placed after the dehydration process and is connected to a dryer, and 60 is laundry that is going to be dehydrated or an aggregate thereof. is there.

Next, the operation will be described. The dehydrator is in the state shown in FIG. 6, namely, the conveyor belt 40 is stopped, the basket 42 is in the lowered position,
With the piston rod 51 in the raised position, a continuous washing machine
From 58, a substantial amount of laundry 60 is loaded into the basket 42. Next, when the hydraulic device 48 is actuated in response to the completion signal from the continuous water washing machine 58, the piston rod 51 is lowered and the pressurizing body 53 pressurizes the laundry 60.

The laundry 60 is pressed by a pressurizing body 53 attached to a press plate 52 fixed to the tip of the piston rod 51 (Fig. 7). At this time, since the encapsulating liquid 56 is contained in the pressurizing body 53, the laundry 60 receives uniform pressure and is uniformly dehydrated. Since the guide 57 has substantially the same size as the inner surface of the basket 42, direct contact between the press plate 52 itself and the inner surface of the basket 42 can be prevented. Therefore, the press plate 52 and the inner surface of the basket 42 do not come into contact with each other, and the press plate 52
Operates with the center of the basket 42, and the pressurizing body 53 presses the entire surface of the laundry 60 with a uniform pressure by the action of the enclosed liquid 56. The guide 57 is preferably made of resin, rubber, or a copper-based metal having a sufficient slidability so that the guide 57 does not cause a problem even if it comes into contact with the basket 42.

Next, when a timer (not shown) set in consideration of sufficient dehydration and the dehydration cycle times out, the circuit of the hydraulic device 48 is switched and the piston rod 51 is slightly raised as shown in FIG. Further, when the raising / lowering drive device 46 is operated after the pressurization state by the pressurizing body 53 is released by a timer or the like (not shown), the basket 42 engaged with the chain or the like is raised as shown in FIG.

At this time, when the laundry 60 is a soft material, such as a towel, the lower surface of the pressurizing body 53 and the laundry 60 are in close contact with each other, so that when the pressing body 53 rises, its interface becomes a negative pressure state. ,
The laundry 60 does not fall off the conveyor belt 40 without being peeled off from the pressure body 53. In this state, the piston rod 51 ascends, so that the laundry 60 will enter the basket 42 again. In this case, the dehydrated laundry 60 is not sent to the next process, and the basket 42 shifts to the next operation with the laundry stored therein.

When the drive roll 41 is rotated in the direction of the arrow by a signal detected by the limit switch or the like (not shown) of the rise of the basket 42, the laundry 60 is not discharged onto the conveyor 59 as the conveyor belt 40 rotates. Regardless, the conveyor 59 operates. Then, after operating for a certain period of time by a timer (not shown), the rotation of the drive roll 41 is stopped. Next, by the stop signal of the drive roll 41, the basket 42 is lowered to the lowered position on the conveyor belt 40 and the piston rod 51 is raised to the raised position in the same manner as described above to restore the state of FIG.

At this time, the laundry 60 is kept in close contact with the pressurizing body 53, or is moved into the basket 42 by the frictional force with the basket 42 when it rises while being in close contact with the pressurizing body 53. It has been dropped. Normally, the dehydrated laundry 60 self-expands due to the elasticity of the laundry itself when the squeezing force is released. Therefore, even when the laundry 60 is in close contact with the pressure body 53 as shown in FIG. It is scraped off at the end of the lower surface of 42, but in the case of a soft material, this self-expansion force is small, so it will re-enter the basket 42 while being in close contact with the pressing body as in the previous term. The dehydrator intermittently performs dehydration by repeating the above-mentioned actions in a cycle of 1.5 to 2 minutes.

(Problems to be solved by the invention) When a soft material such as a towel is dehydrated in a conventional washing machine in the first half, the dehydrated laundry does not peel off from the pressurizing body and rises in close contact with the basket. Sometimes it was left in 42. However, also in this case, the next laundry discharged from the continuous washing machine 58 is put into the basket 42, so that twice the usual laundry cannot be accommodated in the basket 42. . Therefore, in this case, since it is necessary to take out the wet laundry 60 from the basket 42 by hand, the productivity is remarkably reduced and the work is performed by putting the hand under the pressurizing member, which is a very dangerous work. Met.

The present invention is intended to solve the conventional problems in the previous term by providing a shock device and changing the volume of the enclosed water in the pressurizing body at the end of dehydration.

(Means for Solving the Problems) For this reason, the present invention provides a device for dewatering water from clothes or the like after washing by squeezing a pressurizing body which is moved up and down by an operation of a piston from the upper part. A shock device that changes the internal volume of the pressurizing body is attached to the mounting press plate, and when the pressurizing body is lowered to dehydrate and then lifted, the internal volume of the pressurizing body is increased or decreased. I made it,
This is a means for solving the problem.

(Function) A shock device is attached to the press plate to which the pressurizing body is attached, and the water bound to the enclosed water is interposed in the moving space of the piston that is pressed by the spring. The volume of the enclosed water in the pressurizing body is changed by introducing air or the like, or compressed air is taken in and out from the elastic body inserted into the pressurizing body, and the lower surface of the pressurizing body is removed by repeating this once or more. Deform and drop the laundry.

(Embodiment) Hereinafter, the present invention will be described with reference to the embodiments of the drawings. Figs. 1 to 5 show an embodiment of the present invention, and reference numerals 35 to 44, 46, 47 ...
Since the parts indicated by 60 and 62 are the same as those shown in FIG. 6, detailed description thereof will be omitted here, and only the points different from FIG. 6 will be described.

In the figure, reference numeral 81 is a shock device, which is attached to the upper surface of the press plate 52. Inside the shock device 81, a compression spring 87 is provided.
The piston 84 pushed by is inserted, and the piston 84
O-ring 85 between the inner surface of cylinder 86 of shock device 81 and
It is sealed with. The intervening water 82 is filled in the space in which the piston 84 has been pushed away by the compression spring 87, which is in conduction with the enclosed water 56. Further, 80 is compressed air, which is sent from a solenoid valve (not shown).

Next, the operation will be described. As shown in FIG.
The volume of the enclosed water 56 is constant while squeezing.

Next, when the dehydration process ends and the piston rod 51 rises as shown in FIG. 3, compressed air 80 is supplied to the cylinder of the shock device 81.
Introduce it into 86 and move the piston 84 to move the intervening water 82 to the arrow.
As shown in FIG. 83, it is introduced into the pressurizing body 53 and filled water 56 in the pressurizing body 53.
Increase the volume of.

At this time, since water is generally an incompressible fluid,
The lower surface of 53 is deformed as shown in FIG. As a result, the contact state between the laundry 60 and the pressure body 53 is broken, the negative pressure is released, and the laundry 60 drops onto the conveyor 40. At this time, if the compressed air 80 is taken in and out in a short time, a shock is given to the lower surface of the pressurizing body 53, and it becomes easier to peel it off.

Next, FIGS. 4 and 5 show a second embodiment of the present invention, in which 92 is an elastic bag, for example, a rubber bag, 91 is a solenoid valve, 93 is an introduction pipe, and 94 is introduced air. , These constitute a shock device. FIG. 4 shows a state where air is introduced through the solenoid valve 91, and the lower surface of the pressurizing body 53 is convex downward. Figure 5 shows the pressurizing body in the pressing process.
53, the elastic body 92 is closed by the pressing force.

The operation of the embodiment shown in FIGS. 4 and 5 will now be described. As with the first embodiment, the arrow 90 in FIG.
The air 94 introduced as described above changes the volume in the pressurizing body 53 to give a shock to the lower surface of the pressurizing body 53,
The laundry 60 stuck due to the vacuum state is dropped onto the conveyor. Also in this case, if this operation is repeated a plurality of times, the number of times of giving a shock increases, so that the laundry 60 can be reliably peeled off.

(Effect of the Invention) As described in detail above, according to the present invention, the press plate for mounting the pressure body is provided with the shock device for changing the internal volume of the pressure body. It is possible to avoid stopping the machine in the middle of production because it does not rise up in the state where it is in close contact with the basket and re-enters the basket again, so that it will not be mixed with the laundry to be sent next. Therefore, productivity can be improved, and dangerous work such as taking out wet laundry from the basket by hand can be eliminated.
