Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a washing mechanism for washing objects suitable for washing bedding such as futons and blankets.

[Conventional technology]

As futons are used, sweat deposits emitted from the body adhere to and are absorbed, but this sweat deposits contain water, salt, fat, and protein, which cannot be completely removed by washing. In this case, new sweat is added, and its components undergo chemical changes and become oxidized. When sweat plaque is butylated in this way,
Butyric acid, which is a weak acid, causes a yellowing phenomenon that causes the fibers of the futon to deteriorate and fall apart.

In addition, in general households, futons that absorb sweat are dried in the sun, and although this has a sterilizing effect by removing moisture and drying it, it also removes the salt and fat contained in the sweat. However, since the protein remains as it is, it is not an essential solution.

Therefore, in order to prevent the above-mentioned yellowing phenomenon, it is necessary to wash futons, etc., but conventional methods for washing futons, etc. include unsewing and replacing cotton,
There is a method of washing the futon, etc., but the former involves removing the deteriorated and tattered cotton, which is time consuming and labor intensive, so washing the futon etc. is done.

This conventional washing method includes washing bedding such as futons by placing them in a washing tank and stirring or rotating them, or washing the bedding by spraying a cleaning liquid and brushing the bedding. There was a way to clean it.

[Problem to be solved by the invention]

However, in the above-mentioned conventional method of washing bedding by placing it in a washing tank and stirring or rotating it, the bedding is washed while being pressed, pulled, or twisted from a free direction, so that the fabric is washed. Also, there is a problem that the cotton tends to become twisted or entangled, causing deformation and damage to the fabric or cotton.

In addition, with the method of brushing by spraying a cleaning liquid, the dirt on the brushed surface is removed, but it is difficult to brush the entire surface uniformly, and there is a problem that it is not effective against dirt that has penetrated into the interior. It was hot.

Furthermore, with the conventional washing means described above, it is difficult to wash a large amount of bedding at the same time and uniformly, and moreover, water is not enough for 5 to 6 futons.
The problem was that it required about 2.5 tons.

The present invention has been made in view of the above circumstances, and aims to provide a mechanism for washing objects to be washed, which can simultaneously wash a large amount of objects to be washed, such as futons, and which can clean the insides of the objects evenly. purpose.

[Means to solve the problem]

A mechanism for washing objects to be cleaned according to the present invention in accordance with the above object includes a cleaning tank including an inner tank arranged with a gap inside and having a large number of water holes formed in the side and bottom part, and the inner tank. a plurality of net shelves, each of which is movable up and down, on which objects to be cleaned are placed; a presser plate provided at the top of the net shelf and provided with a large number of water holes to press the net shelf in the vertical direction; a bendable connection member that connects the holding plate and the plurality of mesh shelves with a gap; a reciprocating means for reciprocating the holding plate attached to the lid of the cleaning tank within the washing tank; and the cleaning unit. a mounting cart disposed outside the tank; a mount that straddles the washing tank and the mounting mount; a cart mounted on the mount and reciprocating between the washing tank and the mounting cart; The apparatus includes a deceleration motor that raises and lowers the object to be cleaned in a suspended state together with the lid and the reciprocating means.

Here, the term "net shelf" includes not only a case where the shelf is made of net material but also a case where bars or wires are arranged in a grid pattern or in parallel at predetermined intervals.

Further, it is preferable that the mutual net shelves are connected by a connecting member that can be bent in the vertical direction, and further, the reciprocating means is constituted by a screw mechanism and a motor that drives the screw mechanism. It's okay.

[Effect]

In the mechanism for washing objects to be cleaned according to the present invention, a plurality of net shelves are connected with a gap by a topmost holding plate and a flexible connecting member, and the holding plate is moved in a reciprocating manner by a reciprocating means. Since the object to be cleaned is placed in the net shelf and the presser plate is moved back and forth, the object to be cleaned at the lowest stage is also pressed because the net shelves are connected to each other by a bending connecting member. Also, due to the reciprocating movement, the cleaning liquid inside the cleaning tank flows out through the water holes provided in the sides and bottom of the inner tank, as well as the holding plate, and the objects to be cleaned placed on the rack are smoothly pushed. It will be washed.

Furthermore, since the individual objects to be cleaned are placed on net shelves arranged at predetermined intervals in their free state,
When the pressing state of the pressing plate is released, the fibers and cotton return to their original state due to their elasticity, and as a result, the cleaning liquid is absorbed inside.

In this case, by placing the items to be cleaned spread out on a net shelf, the items to be cleaned will be washed in their original shape and will not lose their shape.Furthermore, since the items to be cleaned are washed by force as described above, the items to be cleaned will The detergent reaches even the inside of the body, which allows the inside to be washed evenly and reliably.

Furthermore, by matching the inner tank to the shape of the object to be cleaned, the amount of water used can be saved.

Furthermore, in order to take the object to be cleaned into and out of the cleaning tank, a deceleration motor operates to raise and lower the object to be cleaned together with the lid and the reciprocating means in a suspended state, and a cart moves along the pedestal to move the object into and out of the cleaning tank. This can be easily done by moving back and forth between the mounting carts.

It is a side view of the complete washing mechanism of the object to be washed.

As shown in FIGS. 1 and 3, a mechanism 10 for washing objects to be cleaned according to an embodiment of the present invention includes a cleaning tank 11 containing a cleaning liquid therein, and a cleaning mechanism 10 disposed inside the cleaning tank 11. A plurality of net shelves 12 and the net shelves 12
, a reciprocating means 14 for reciprocating the presser plate 13 in the washing tank, a cart 15 constituting a conveying means for conveying the net shelf 12, and the cart 15. It is configured to have a supporting frame 16. These will be explained in detail below.

The cleaning tank 11 is made of a metal or plastic container, and there are many water holes 1 all around the inside.
An inner tank 17 is provided, in which the inner tank 6a is formed.
A plurality of net shelves 12 are arranged at 7. As shown in Fig. 2, this mesh shelf 12 consists of four shelves, each of which is made of two mesh welded wire meshes with a wire diameter of 1.63 mm attached to the top and bottom surfaces of a pipe frame. They are connected by a chain 18, which is an example, and are suspended from the top plate 13 via a chain 19, which is an example of a removable and bendable connection member.

The holding plate 13 is suitably provided with water passage holes 21, and the holding plate 13 is connected to the output shafts of screw jacks 22 constituting the reciprocating means 14 by four guide rods 20, respectively.

This screw jack 22 is mounted on a pedestal 24 provided on the lid 23, and each input shaft is connected to a single motor (not shown) via a gear box 25 having four synchronously rotating output shafts. . This motor is rotated forward and backward by appropriate control means to cause the presser plate 13 to reciprocate.

The motor is a DC motor whose rotation speed can be controlled or an AC motor controlled by an inverter, and the motor rotates at a preset rotation speed and time depending on the type and amount of objects to be cleaned. It's summery.

There are four roller chains 2 at the four corners of the lid 23.
The roller chain 26 is engaged with a hoisting sprocket 28 connected to a deceleration motor (not shown), and the roller chain 27 is coaxially connected to the hoisting sprocket 28 via an idle sprocket 29. It is meshed with a winding sprocket with the same number of teeth provided on the The winding sprocket 28,
The idle sprocket 29 and the deceleration motor are attached to a trolley 15 that runs on rails 30 and 31 placed on a pedestal 16 by a drive source (not shown), and is shown in FIG. 3 with the lid 23 suspended. As shown, it is possible to travel a predetermined distance.

Further, on the side surface of the cleaning tank 11, a pipe 32 for introducing cleaning liquid or water and a stop valve 33 connected to the pipe 32 are provided. The bottom of the cleaning tank 11 is inclined toward the center, and a drain pipe 35 having a stop valve 34 in the middle is connected to the center.

Next, the operation of the mechanism 10 for washing objects to be cleaned according to the above embodiment will be explained in more detail.

First, as shown by the two-dot chain line in FIG. Place it in the specified position.

Next, the net shelves 12 on which the futons 36 to be washed are placed and whose four corners are connected by chains 18 are transported by the loading cart 37, and
2 is attached to the holding plate 13 by a chain 19. Note that the futon 36 may be loaded onto the net shelf 12 while the net shelf 12 is suspended from the holding plate 13.

Then, the trolley 15 is moved to transport the net shelf 12 above the washing tank 11, the hoisting sprocket 28 is loosened, and the lid 23 is placed over the washing tank 11.

Next, the stop valve 33 is loosened and the cleaning liquid is poured into the cleaning tank 11 to a predetermined level. This predetermined level is detected by a liquid level gauge (not shown). When it is detected that the cleaning liquid has entered to a predetermined level, the motor connected to the gear box 25 is rotated in a predetermined direction, and the presser plate 13 is lowered. As a result, the futon 3 placed on the net shelf 12
6 is pressed by the pressing plate 13 to discharge the cleaning liquid and air that have penetrated into the inside of the futon 36. Next, a limit switch (not shown) detects that the presser plate 13 has been lowered to a predetermined position, and the motor is reversed to raise the presser plate 13. As a result, the pressed state of the futon 36 resting on the net shelf 12 is released, and the cleaning liquid is absorbed again by the elasticity of the internal fibers. In this case, it is preferable that the pressing plate 13 is moved back and forth once every 40 seconds, and the pressure washing is performed by repeating 15 to 20 back and forth movements. The futon is cleaned by the above steps, and a flow of cleaning liquid is generated inside the futon, thereby removing sweat and other grime adhering to or seeping into the futon.

After completing the reciprocating movement for a predetermined time, the presser plate 13
is raised, the lower stop valve 34 is opened, and the cleaning liquid is once discharged, and then the pressing plate 13 is lowered again to squeeze out the cleaning liquid that has permeated the futon, and the cleaning liquid is almost completely discharged. Then, with the stop valve 34 closed again, the stop valve 33 on the side is opened to let tap water into the washing tank. Note that the tap water piping can also be provided separately from the pipe 32 described above.

With a predetermined amount of water in the cleaning tank 11, the motor is rotated to reciprocate the holding plate 13. Next, open the lower stop valve 34 and lower the presser plate 13 to drain the rinsing water, and if necessary, repeat the above steps again.
The cleaning solution should be almost completely removed from the futon.

Finally, after lowering the holding plate 13 to sufficiently remove water, the holding plate 13 is raised, and then the hoisting sprocket 28 is driven to lift the lid 23, and the futon 36 is placed on the trolley 15 together with the net shelf 12. The product is transported to the top of the carriage 37, the holding plate 13 is lowered appropriately, the chain 19 is removed, and the cleaning process is completed by placing the chain 19 on the mounting carriage 37. In the above examples, the amount of water used was about 1 to 1.5 tons for 5 to 6 futons.

In the above embodiment, the distance to which the holding plate 13 is driven is controlled by a limit switch (not shown). It is also possible to have the board stop when the futon is pushed and the presser board rise.By doing this, when washing various types of bedding, it is possible to press the futon securely without determining the lower limit position. Can be washed.

Further, in the above embodiment, a motor is used as the drive source for reciprocating the presser plate 13, but a hydraulic or pneumatic cylinder may also be used, and moreover, multiple cylinders can be moved synchronously to keep the presser plate horizontal. It is also possible to perform a constant reciprocating motion.

Furthermore, although the above-mentioned presser plate is arranged at the upper part of the net shelf 12, it is also possible to arrange the presser plate at the lower part of the net shelf to prevent the upper lid from moving and press the futon from the lower part.

〔Effect of the invention〕

As is clear from the above description, in the mechanism for washing objects to be cleaned according to the present invention, a holding plate provided with a large number of water passage holes moves back and forth to push and wash objects placed on a plurality of mesh shelves. Therefore, sweat stains that have penetrated into the inside of the object to be cleaned can be removed without causing the object to lose its shape.

In addition, since there are many water holes on the side and bottom of the holding plate and the inner tank, the cleaning water flows in and out through the holes, and the objects to be cleaned that are placed on the net shelf are washed smoothly. can do.

Furthermore, since multiple objects to be cleaned can be processed simultaneously, work efficiency can be improved for commercial use.

Furthermore, the washing mechanism for the object to be cleaned allows rinsing and dehydration to some extent to be carried out without causing the object to lose its shape, making it possible to use the apparatus extremely efficiently.

Further, a cart mounted on a pedestal and reciprocated between the washing tank and the mounting cart, and a reduction motor attached to the cart and lifting and lowering the object to be cleaned together with the lid and the reciprocating means in a suspended state. Since we have
By operating the reduction motor and reciprocating the trolley between the cleaning tank and the mounting trolley, objects to be cleaned can be taken in and out of the inner tank without requiring any effort.
