Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a mat cleaning machine for car floor mats, entrance mats, etc., and in particular, the present invention relates to a mat cleaning machine for car floor mats, entrance mats, etc. It is something.

(Prior Art) Mat cleaning machines have been widely known that supply mats between a plurality of rotating brushes and wash the mats with water. This type of mat cleaning machine is generally provided with a squeezing roller to squeeze out moisture adhering to the mat after washing with water. This squeezing reroller consists of a fixed squeezing roller fixed to a frame and a movable squeezing roller that is pressed against the fixed squeezing roller by a force such as a spring.By sandwiching the mat supplied between both rollers, the mat It narrows down the

By the way, in a conventional mat cleaning machine, in order to press both rollers together when squeezing the mat, a separating operation lever is rotatably provided on the frame of the mat cleaning machine, and this operation lever and the movable squeezing roller are linked. At the same time, a spring is provided between the operating lever and the frame, and the spring draws the operating lever and the movable aperture roller interlocked thereto toward the fixed aperture roller. In order to separate the movable squeezing roller from the fixed squeezing roller when the mat cleaning machine stops operating, the operating lever provided on the frame is rotated against the spring, and the movable squeezing roller interlocked with the operating lever is moved away from the fixed squeezing roller. He was separated from Laura.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional technology, when the movable squeezing roller is pulled apart, the operating lever is rotated against the force of the crimping spring. The drawback was that it required a large amount of force to rotate.

In particular, the conventional spring was stretched between the operating lever and the frame, and the spring force was always applied to the operating lever.As the movable aperture roller is pulled apart, the spring stretches and its tensile resistance increases, causing the movable aperture It was difficult to lock the rollers in the separated position.

The present invention solves the problems of the prior art as described above, and its purpose is to make it possible to press and separate a movable squeezing roller and a fixed squeezing roller with a light operating force, and to make it possible to press and separate a movable squeezing roller and a fixed squeezing roller, and to make it possible to press and separate a movable squeezing roller and a fixed squeezing roller. To provide a mat cleaning machine which can obtain a suitable pressure bonding force.

[Structure of the Invention] (Means for Solving the Problem) In order to achieve the above object, the mat cleaning machine of the present invention has the following features: Both ends of the shaft of the movable squeezing roller are arranged at both ends of the movable squeezing roller. The roller-side link is movably supported toward the fixed aperture roller, and between this roller-side link and the shaft of the movable aperture roller, there is a pressure spring that urges the movable aperture roller toward the fixed aperture roller. The spindle provided on the frame rotatably supports an operating lever for moving the movable aperture roller toward and away from the fixed aperture roller, and a lever-side link that rotates together with this operating lever. The lever-side link and the roller-side link are connected by a connecting link, and when a force is applied to the roller-side link in the direction of separating it from the fixed aperture roller, the operation lever or the lever-side link interlocked therewith is rotated. This feature is characterized by the provision of a stopper to prevent movement.

(Function) In the present invention having the above configuration, when the operating lever is rotated to move the movable aperture roller toward the fixed aperture roller, the movable aperture roller does not move until the movable aperture roller contacts the fixed aperture roller. Since the crimping spring installed on the roller side link that supports the squeezing roller also moves together with the movable squeezing roller, the force of the crimping spring does not interfere with the movement of the operating lever or the movable squeezing roller, allowing operation with light force. I can do it.

Even after the movable aperture roller contacts the fixed aperture roller and cannot move any further, if the operating lever is further rotated, only the roller-side link that supports the movable roller will move toward the fixed aperture roller. At this time, a pressing spring is compressed between the movable squeeze roller which cannot be moved and the movable roller side link, and the movable squeeze roller is pressed against the fixed squeeze roller by its elastic force.

On the other hand, when the operating lever is rotated over a certain angle toward the crimping side of the fixed squeezing roller, the positional relationship of the lever-side link, connecting link, and roller-side link that interlock with the operating lever changes, and the crimping spring The roller-side link, which attempts to move in the direction of separating from the fixed squeezing roller due to reaction force, urges the lever-side link and operating lever to the fixed squeezing roller's crimping side, causing the lever-side link or operating lever to press against the fixed squeezing roller. Since the movable squeezing roller is brought into contact with the stopper on the position side, the movable squeezing roller is held at the pressing position even if the operating lever is released.

(Example) Configuration of this Example* Hereinafter, an example of the present invention will be specifically described based on FIGS. 1 to 3.

On the front of the frame of the mat washer, there are guides a
A mat insertion opening 1 is provided.

A fixed feed roller 2 and a movable feed roller 3 that elastically contact the fixed feed roller 2 are provided on the back side of the insertion port 1.

The movable feed roller 3 is rotatably supported at the tip of a bracket 4 rotatably attached to the frame. A spring 5 is provided between the bracket 4 and the frame,
The movable feed roller 3 is pressed against the fixed feed roller 2 by this spring 5. A brush roller 6 is provided downstream of these feed rollers 2 and 3 to support and clean the mat from below. Nozzles 7.7 for spraying cleaning water onto the mat are provided between the feed rollers 2, 3 and the brush roller 6, and these nozzles 7.7 are connected to a water supply pipe 8 via piping (not shown). There is. A water supply pipe 8 is provided with a water flow control valve 9 and a water supply opening/closing valve 10 that is interlocked with the operating lever of the movable squeezing roller.

A fixed aperture roller 11 supported by a frame and a movable aperture roller 12 disposed so as to be movable toward and away from the fixed aperture roller 11 are provided downstream of the brush roller 6. That is, the left and right roller side links 14 are rotatably attached to a fulcrum 13 provided on the frame,
Both ends of the movable aperture roller 12 are supported inside these left and right roller-side links 14. That is, the side plates of the left and right roller-side links 13 are provided with elongated openings 15, and within these openings 15, bearings 16 at both ends of the movable aperture roller 11 are installed.
is supported so that it can slide freely.

A pressure spring 17 is provided in a compressed state between the seat 16a integrally provided on the bearing 16 and the inner surface of the roller-side link 13 for urging the movable squeezing roller 12 toward the fixed squeezing roller 11 side. .

The tip of a lever-side link 19 is connected to the opposite side of the roller-side link 14 from the fulcrum 13 via a connecting link 18 . The base end of this lever-side link 19 is rotatably attached to a support shaft 20 fixed to the frame, and interlocks with an operating lever 21 that also rotates around the support shaft 20.

Further, a water supply pipe opening/closing rod 22 that is interlocked with the operating lever 21 is attached to this support shaft 20 and is connected to the opening/closing valve 10 .

Further, a stopper 23 is provided that prevents the lever-side link 19 from further rotating in the pressing direction when the lever-side link 19 reaches the pressing position of the movable aperture roller 12. Although this stopper 23 contacts the lever-side link 19 in this embodiment, it may also restrict the rotational position of the operating lever 21 in the crimp direction.

Effects of this embodiment* The effects of this embodiment having the above-described configuration are as follows.

■Mat cleaning machine stopped state...Figure 1 In this state,
The operating lever 21 is at the stop position of the mat washer, that is, at a position rotated counterclockwise in the figure, and the lever side link 19 interlocked with this operating lever 21 is also at a position rotated counterclockwise.

Therefore, the roller side link 13 which is interlocked with this lever side link 19 via the connecting link 18 rotates clockwise about the fulcrum 13, so this roller side link 1
The movable aperture roller 12 supported by the fixed aperture roller 1
1 is in a separated state.

In addition, in this case, since the operating lever 21 is rotating counterclockwise, the opening/closing valve 10 of the water supply pipe is also in the closed position by being pressed by the opening/closing rod 22 that interlocks with the operating lever 21, and the nozzle 7.7 is filled with cleaning water. is never sent.

■When the mat cleaning machine starts operating...Fig. 2 When the operating lever 21 is rotated clockwise from the stopped state shown in Fig. 1, a power switch (not shown) linked with this is turned on, and the fixed feed roller 2, Brush roller 6 and fixed aperture roller 11
starts rotating by a drive mechanism (not shown). Since the opening/closing rod 22 also moves at the same time, the opening/closing valve 10 linked thereto opens and the cleaning water is sent to the nozzle 7.7.

On the other hand, as the operating lever 21 rotates, the roller-side link 14, which is interlocked with the operating lever 21 via the lever-side link 19 and the connecting link 18, rotates counterclockwise about the fulcrum 13. As a result, the movable aperture roller 12 supported by this roller-side link 14 moves toward the fixed aperture roller 11 side.

In this case, before the movable aperture roller 12 contacts the fixed aperture roller 11, the pressing force of the compression spring 17 acts only to press the bearing 16 of the movable aperture roller 12 against the opening 15 of the roller side link. Therefore, the compression spring 17 does not interfere with the operation of the operating lever 21.

■When pressing the movable aperture roller...Fig. 3 Operation lever 21
When further rotated, the surfaces of both squeezing rollers 11 and 12 come into contact and as they deform, the crimping resistance overcomes the force of the crimping spring 17, so the crimping spring 17 is compressed and the roller side link 14 moves toward the fixed aperture roller 11.

At this time, the bearing 16 of the movable aperture roller 12 moves within the opening 16 of the roller-side link 14 to the side opposite to the fixed aperture roller 11 .

By the way, when the operation lever 21 is rotated clockwise and each connection point of the lever-side link 19, connection link 18, and roller-side link 14 exceeds the intermediate point, the clockwise rotational force of the roller-side link 14 is It acts as a force that urges the lever-side link 19 clockwise. Therefore, in this embodiment, by bringing the lever-side link 19 into contact with the stopper 23 at a position beyond the intermediate point, the roller-side link 14 is prevented from rotating clockwise due to the reaction force of the compression spring 17. The elastic force of the spring 17 acts as a pressing force on the movable aperture roller 12. Also, by utilizing the force of the roller-side link 14 to rotate due to the reaction force of the compression spring 17, the lever-side link 19 is brought into contact with the stopper 23, and the operation lever 21 is moved to the operating position of the mat washer. I am keeping it.

When a mat to be cleaned is inserted from the insertion port 1 in this state, the mat is sandwiched between the feed rollers 2 and 3 and sent to the brush roller 6, while being sprayed with cleaning water from the nozzle 7.7, and is cleaned. . The mat that has passed through the brush roller 6 is held between squeeze rollers 11 and 12 which are in a compressed state to squeeze out moisture, and then is discharged to the outside of the mat washer. At this time, depending on the thickness of the mat to be washed, the spring 5 expands and contracts to change the distance between the feed rollers 2 and 3, and the amount of compression of the compression spring 17 changes to change the distance between the squeezing rollers 11 and 12. Change.

■When the mat washer is stopped When the mat washer is stopped, the operations from (1) to (3) above are performed in reverse, but by rotating the operating lever 21, the movable squeezing roller 12 is moved from the fixed squeezing roller 11. When separated, the force of the compression spring 17 is received by the edge of the opening 15 of the roller-side link that the bearing 16 comes into contact with, so that it does not interfere with the rotation of the operating lever 21.

[Effects of the Invention] As described in "2" below, according to the present invention, a movable aperture roller is movably supported inside a roller-side link that is rotated by an operation lever, and a movable aperture roller is fixedly attached to this roller-side link. By providing a pressure spring on the roller, the force of the pressure spring is not transmitted to the operating lever except when the movable aperture roller and the fixed aperture roller are crimped together, making the rotation of the operating lever extremely light. It is possible to provide a mat cleaning machine that can be cleaned by force.
