Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat washing machine for washing floor mats, entrance mats, etc. of automobiles with water, and more particularly, to a mat having an improved mechanism for squeezing out moisture of the mat after washing. Related to washing machine.

[0002]

2. Description of the Related Art Conventionally, a mat washing machine for washing a floor mat of an automobile with water has been widely used in gas stations and the like. This type of mat washing machine is to wash a mat fed inside by a feed roller with a rotating brush roller. Generally, such a mat cleaning machine is provided with a squeezing roller for squeezing out moisture adhering to the mat after washing with water. This squeezing roller is constituted by a roller that sandwiches the mat from above and below. However, since it has the purpose of squeezing out moisture, it needs to be rotated in a state where it is strongly pressed from above and below. Therefore, the squeezing rollers must always be urged in a direction in which they are pressed against each other by a strong pressing spring or the like. However, even after the work is completed and the stop roller is stopped, if the pressure contact state is maintained as it is and the roller is left untouched, the roller may be deformed. Especially in winter, the washing water attached to the rollers freezes,
There is a problem that the upper and lower rollers are damaged and starting is difficult.

In order to cope with this, in a conventional mat cleaning machine, a pressing operation of the squeezing roller and an operation of separating the pressing roller are performed by the force of an operation lever for ON / OFF. That is, when the switch is turned on by tilting the operation lever, the feed roller, the brush roller, and the squeezing roller start rotating, and the force of the spring is applied to the upper and lower squeezing rollers, so that the squeezing rollers are pressed against each other. Then, when the switch is turned off by returning the operation lever, the squeeze roller separates against the force of the spring. In this way, switch ON / OFF
Synchronizing the OFF operation and the pressing / separating operation of the aperture roller can prevent the aperture roller from being deformed.

[0004] Further, washing water supplied through a water supply pipe is jetted onto the mat being washed by the brush roller, and a valve operation for supplying / stopping the washing water is usually performed. The operation is performed by the operation lever.

[0005]

However, one example of the above-mentioned mat cleaning machine has the following points to be improved. That is, in order to effectively squeeze out the washing water adhered to the mat, it is necessary to make the pressure of the upper and lower squeezing rollers extremely large. For this reason, the spring for pressing the squeeze roller must use a large force,
On the contrary, the operating force required to completely open the squeezing roller also becomes very large. Therefore, it is difficult for a weak operator to completely raise and lower the operation lever, and even if the switch is turned off, the aperture roller is left in a state where the aperture roller is pressed, or if the switch is turned on, the aperture roller is not pressed. Is more likely to occur. Especially,
Recently, there are many women as employees of gas stations, and it can be said that a mat washer that can be operated with light power is more desirable. However, such a configuration does not meet such a demand.

[0006] However, most of the driving force of the operating lever is transmitted using a lever force, so that the operating force can be reduced to some extent by making the operating lever longer. However, when the operation lever is lengthened in this way, there is a problem that the entire mat washer becomes large.

Conventionally, as described above, the ON / OFF operation of the switch, the pressing / opening operation of the squeezing roller, and the valve operation of supplying / stopping the washing water have been performed by one operating lever. However, the valve operation for adjusting the amount of washing water had to be performed by another lever for the following reason. That is, in order to press and separate the aperture roller, it is necessary to completely tilt the operation lever to the ON position or the OFF position. However, in the case of adjusting the amount of water, it is necessary to perform an operation such as stopping the lever at an intermediate position according to a desired amount of water. Therefore, it is difficult to adjust the amount of water by using the one operation lever. Therefore, the conventional mat washer requires two levers for ON / OFF and water amount adjustment, and two valves for water supply / stop and water amount adjustment on the water supply pipe. Therefore, the number of parts has increased.

The present invention has been developed in order to solve the above-mentioned problems of the prior art. The main objects of the present invention are to operate and stop a drive source, and to press and release an aperture roller. Is to provide a mat washer that can be performed synchronously with a light force.

Another object of the present invention is to perform a single operation lever for operation / stop operation of a drive source, pressure operation / opening operation of a squeeze roller, supply / stop operation of a cleaning liquid, and adjustment operation of a cleaning liquid amount. It is an object of the present invention to provide a mat washing machine capable of performing the above-mentioned.

[0010]

In order to achieve the above object, the present invention provides a feed mechanism for transferring an inserted mat, a cleaning mechanism for cleaning the mat taken in by the feed mechanism with a cleaning liquid, A squeezing mechanism for squeezing the cleaning liquid from the mat cleaned by the washing mechanism, a driving mechanism for driving the feed mechanism, the cleaning mechanism and the squeezing mechanism with the power of a driving source, and operating / stopping the driving source. A mat cleaning machine having an operation mechanism has the following technical features.

That is, according to the first aspect of the present invention, the iris mechanism has two iris rollers which are rotated by the drive source and are provided so as to be able to sandwich a mat, and at least one of the iris rollers is the other. It is provided so as to be movable in the direction of coming into contact with and separating from the squeezing roller, and has a pressing means for pressing the movable squeezing roller to the other squeezing roller, and in the vicinity of one squeezing roller provided movably, An independently movable separation cam is provided, and a rotation roller, which is rotatable in synchronization with the separation roller provided with the separation roller provided with the separation cam, is provided. The cam comes into contact with the rotating cam when the driving source stops,
It can be moved between a contact position for separating the aperture roller against the pressure force of the compression unit and a release position where the aperture roller is disengaged from the rotary cam when the drive source is operated and the aperture rollers are pressed against each other. And a link mechanism for moving the opening / closing cam between the contact position and the release position in conjunction with the operation / stop operation of the drive source by the operation mechanism. I do.

According to the first aspect of the present invention, when the driving source is operated, the mat taken in by the feed mechanism is cleaned by the cleaning mechanism, and then is held by the two rotating squeezing rollers. During this operation, since the separating cam is at the release position disengaged from the rotating cam, the aperture rollers are pressed against each other by the pressing means. Therefore, the cleaning liquid is sufficiently squeezed out by the two squeezing rollers. When the operation of the drive source is stopped by the operation mechanism, the separating cam is moved to the contact position side by the link mechanism and contacts the rotating cam. Then, due to the inertial rotational force of the rotating cam, a force opposing the pressing force of the pressing unit acts on the separation cam and one of the aperture rollers, and the two aperture rollers stop in a separated state.

According to a second aspect of the present invention, in the mat washer of the first aspect, there is provided a return means for constantly urging the opening cam toward the release position.

According to the second aspect of the present invention, since the separating cam is always urged toward the release position by the return means, the operation of the drive source is started from the stopped state.
When the contact between the separating cam and the rotating cam is released, the separating cam automatically returns to the release position.

According to a third aspect of the present invention, in the mat washer according to the first or second aspect, the operating mechanism includes a switch of the driving source, and a peripheral portion thereof is moved toward or away from the switch by moving or rotating. A switch cam for turning on and off the switch, and an operation lever provided rotatably and interlocked with the switch cam, and while the operation lever is turning, the switch is kept turned on. A peripheral portion of the switch cam is formed so that the switch is turned off only when the operation lever reaches one rotation end.

According to the third aspect of the present invention, when the operation lever is turned in the closing direction, the switch of the driving source is turned on by the switch cam, and the mat washer is operated. When the operating lever is turned in the blocking direction from this operating state, the switch is maintained in the ON state by the switch cam during the turning. When the operation lever is turned to the turning end, the switch is turned off by the switch cam.

According to a fourth aspect of the present invention, in the mat cleaning machine according to the third aspect, the cleaning mechanism includes an injection unit that injects the cleaning liquid to the mat being cleaned, and a connection pipe that supplies the cleaning liquid to the injection unit. And a valve for adjusting the amount of liquid flowing in the connection pipe, wherein the operating lever is connected to an adjusting mechanism of the valve.

According to the fourth aspect of the present invention, since the operation lever is connected to the valve, the amount of liquid injected during operation can be adjusted by the amount of rotation of the operation lever. Then, as long as the operation lever does not reach one of the rotation ends, the switch-on state is maintained. Therefore, even if the rotation amount of the operation lever is changed, the operation state is maintained.

The switch 28 of the motor 35 is turned off.

At the same time, the rotating link 19 and the pressing portions 19a and 26a of the switch plate 26 press the urging link 18, and the urging link 18 rotates the urging plate 13. The urging plate 13 is a contact portion 1 of the separating cam 17.
7b, the separating cam 17 also rotates as shown in FIG. 11, and its outer periphery enters the rotation orbit of the rotating cam 16. For this reason, as shown in FIGS.
The periphery of the rotating cam 16 rotating by inertia after the switch 28 is turned off comes into contact with the periphery of the separating cam 17, and the separating cam 17 is pushed up by the rotational force of the rotating cam 16. Can be Then, the movable throttle roller 12 provided coaxially with the separating cam 17 moves in a direction away from the fixed throttle roller 11 against the urging force of the pressure spring 15. As a result, the pressure stop between the fixed squeeze roller 11 and the movable squeeze roller 12 is stopped in a state where they are separated.

When restarting the mat washer from the above-mentioned stopped state, the operation lever 21 is rotated upward. Then, as shown in FIGS. 7 and 6, the rotating link 19 rotates clockwise in the figure via the operation plate 21a and the slide link 20, and the pressing portion 19a separates from the urging link 18, and the slide link 20 Is held by the magnet above the holding portion 29, so that the angle is maintained. On the other hand, as shown in FIGS. 9 and 8, the switch plate 26 coaxial with the rotation link 19 rotates counterclockwise in the drawing.
The knob 28a of the switch 28 contacts the arc-shaped portion of the switch cam 26b, and the switch 28 of the motor 35 is turned on.

When the motor 35 operates, the fixed aperture roller 11 rotates as described above during operation,
The rotary cam 16 also rotates together with this. Then, FIG.
As shown in FIG. 7, the separating cam 17 which is in contact with the rotating cam 16 also rotates. When both cams 16 and 17 continue to rotate,
When the stopper 14b reaches a position where the stopper 14b enters the notch 17a of the separation cam 17, the rotation cam 16
Leaves. As a result, the movable aperture roller 12 is pressed downward by the urging force of the pressure lever 14 and the pressure spring 15 and presses against the fixed aperture roller 11, so that the driven rotation starts.

The separating cam 17, which has come out of engagement with the rotating cam 16, is urged by the return spring 24 that pulls the wire 22 through the pulley 25. Turning in the opposite direction, FIG.
It is pulled back to the original position shown in. Thereafter, the rear edge of the separating cam 17 hits the stopper 14b, and the separating cam 17 is positioned.

In the first operation, there is no need for a force against the strong pressure spring 15 for pressing the movable aperture roller 12. After the operation of the operation lever 21, the movable aperture roller 12 and the fixed aperture roller 11 are automatically separated and pressed by the operation of the separation cam 17 and the rotating cam 16. Therefore, even if the operator has a weak force, the operation lever can be completely returned, and even if the squeezing rollers 11 and 12 are left in a pressed state after the switch is turned off or the switch is turned on. There is no possibility that the squeeze rollers 11 and 12 are not pressed.

Also, without lengthening the operation lever 21,
Since the force required for the operation can be reduced, the entire mat washer does not increase in size.

Further, the ON / OFF operation of the switch, the operation of pressing / opening the squeezing roller, the operation of a valve for supplying / stopping the washing water, and the operation of a valve for adjusting the amount of washing water are performed by one operating lever 21. In addition, since only one valve 9 is provided on the water supply pipe, the number of parts is small and the production cost is saved.

(4) Other Embodiments The present invention is not limited to the above embodiments, and the arrangement, size, shape, material, and the like of each member can be changed as appropriate.

For example, one embodiment as shown in FIG. 16 can be configured. That is, the movable aperture roller 12

The separation cam 38 is formed with a projection 38a that comes into contact with the rotation cam 16 depending on the movement position.

The operation and effect of the embodiment having such a configuration are as follows. That is, during operation, the separating cam 38 is separated from the movable throttle roller 12 by the urging force of the return spring. Therefore, the movable aperture roller 12 is pressed against the fixed aperture roller 11. Next, when the operation is stopped, the opening cam 38 is moved toward the movable throttle roller 12 in conjunction with the lever operation for stopping. Then, the rotating cam 16 that rotates by inertia comes into contact with the projection 38 a of the separating cam 38, so that the separating cam 38 further moves in the direction in which it contacts the axis of the movable throttle roller 12. Then, the movable aperture roller 12 is pushed up by the inclined edge of the separating cam 38, the movable aperture roller 12 and the fixed aperture roller 11 are separated, and the fixed aperture roller 11 and the rotating cam 16 are stopped. At the same time, the rotating cam 1
6 is disengaged from the projection 38a by its rotation,
8 is separated from the movable throttle roller 12 by a return spring,
The movable aperture roller 12 is pressed against the fixed aperture roller 11.

As described above, the separating cam for separating the aperture roller need not be coaxial with the movable aperture roller. Basically, the movable aperture roller is provided apart from the rotating cam that is linked to the fixed aperture roller, and lifts the movable aperture roller by contact with the rotating cam when the operation lever is turned downward to turn the switch off. Any structure can be used as long as the structure can be used. An operation lever may be attached to the shaft of the movable aperture roller, and an opening cam may be provided on the operation lever.

The shape of the separating cam is not limited to a sector shape. An elliptical or rectangular shape that has a non-contact portion that does not contact the rotating cam, and a contact portion that contacts the rotating cam, and that, after contact, moves the movable aperture roller in a direction to separate the movable aperture roller from the fixed aperture roller. And other shapes. The peripheral surface of the cam may be shaped so that the radius of the cam gradually increases.

Further, the vertical relationship between the driven side and the driven side of each roller in the above embodiment can be reversed. The means for urging the movable throttle roller may be a means for directly attaching a spring to the shaft and pulling the shaft.

The notch 17a of the separating cam 17 is
