Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a cleaning device for mats for cleaning mats of automobiles.

[Prior Art] Conventionally, in this type of mat cleaning device,
The pair of mat guide rolls or squeeze rolls can be separated from each other by operating the operation lever, etc., and by keeping them apart when the machine is stopped, it is possible to prevent the rolls from freezing or to deform the rolls especially in winter. Preventive measures are being taken. For example, as seen in Japanese Utility Model Publication No. 56-24543, operation of a roll for loading and unloading a mat, energization of a mechanism for driving these and supply of cleaning water are performed in the same operation, and operation is facilitated. There is a matte washing machine that is made to be able to do so, and also can prevent damage to the rollers to prolong the service life.

[Problems to be Solved by the Invention] However, in the conventional device as described above,
As shown in FIG. 5, since the carry-in roller 30 and the water draining roller 31 are directly connected to the operation lever 32 and the control switch 33 via each link, the upper and lower sides of the roller depend on the thickness of the mat inserted between the rollers. The movement is directly transmitted to the operation lever 32, causing the lever to vibrate, or when a thick mat is inserted, the control switch 33 linked with the movement of the lever is turned off.

Further, since the biasing force of the spring that presses the rollers against each other directly appears on the operation lever, there is a disadvantage that the operation force becomes heavy.

Therefore, according to the present invention, even if the roller moves up and down due to the thickness of the mat during mat cleaning, the mat does not transmit the motion to the operation lever and does not affect the control switch, and the operation force of the operation lever is light. The purpose of the present invention is to provide a cleaning device.

[Means for Solving the Problems] In order to solve the above problems and to achieve the object, in the present invention, the rotating shaft end of the squeezing roll that squeezes the mat after cleaning and sends it out of the apparatus main body, A bearing link, which is rotatably mounted and has a fulcrum guide, is fitted to a fulcrum provided at a fixed position on the apparatus main body and is pivotally supported so as to be slidable, and the bearing link is urged in one direction. A biasing member, an intermediate link rotatably supported on the side opposite to the bearing member mounting position with respect to the fulcrum of the bearing link, and a rotatably supported device main body side through the intermediate link. By including an operation lever and an operation lever that is connected to the operation link and switches between detachment and attachment of the guide roll, the vertical movement of the aperture roll is absorbed up to the bearing link when the aperture roll is in pressure contact while the device is operating. , Hand squeeze roll When they are separated from each other, the operation force of the operation lever is reduced by the action of these links.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross sectional view showing the overall construction of an embodiment of the present invention. Reference numeral 1 denotes a main body of the apparatus, which is provided with a mat insertion opening 2 to be cleaned on a front surface thereof and a delivery port 3 on a rear surface thereof. Inside the main body 1, a pair of guide rolls 4, a cleaning brush 5, and a pair of squeeze rolls 6 are respectively arranged in order from the insertion port 2 side, and these are connected to a motor (not shown) and are driven to rotate together with the drive of the device. The mat is transported, washed, and dehydrated. Here, 12 is a mat pressing member made of a plurality of semicircular wires provided facing the cleaning brush, and the mat pressing member and the cleaning brush are in close contact with each other so that the mat to be cleaned can pass therethrough, It prevents the mat from floating during cleaning and acts to obtain a sufficient cleaning effect. Reference numeral 11 denotes an operation lever for switching the detachment / attachment of the squeeze roll 6, which also serves as a control switch of the device, presses the squeeze roll only when the device is driven, and separates the squeeze roll when the device is not in a driving state. A cleaning water nozzle 7 supplies cleaning water to the mat cleaning surface and the cleaning brush. In the lower part of the main body,
A receiving tray 8 for receiving cleaning water sprayed during cleaning, sand removed from the mat to be cleaned, and pebbles is provided.
Reference numeral 9 is a leg portion that holds the main body 1 at an appropriate height above the ground, and 10 is a receiving net that is attached to the leg portion and that receives the cleaned mat coming out from the delivery port 3.

Next, FIG. 2 is an explanatory diagram showing in detail the relationship between the operation lever, the squeeze roll, and the control switch. The rotating shaft 6-b of the lower squeezing roll of the pair of squeezing rolls 6 is supported at a fixed position on the apparatus main body side, while the upper rotating roll is supported so as to freely move up and down according to the thickness of the mat. It The configuration will be described below.

The rotating shaft 6-a of the upper squeezing roller is supported by an independent bearing link 13 which is not fixed to the main body. The bearing link has a rotating shaft supporting portion located substantially in the center thereof, and is connected to a biasing member 16 such as a spring through a hole 15 provided at a portion farthest from the rotating shaft supporting portion. A slit-shaped fulcrum guide 14 having a curvature is provided between the rotary shaft support portion and the hole 15, and a fulcrum 17 protruding from a fixed position on the main body side is fitted therein. Further, at the link end portion on the opposite side, it is rotatably connected at a pivot point 18 to an intermediate link 19 which is a member separate from the bearing link.
The intermediate link 19 is further rotatably connected to the operation link 20 at a pivot point 21 to connect the operation link 20 and the bearing link 13. The operation lever is rotatably supported at a fixed position of the main body at a pivot point 22, and the operation lever 11 and a switching bracket 24 for opening and closing the control switch 23 are provided between the pivot points 21 and 22. With such a configuration, it is possible to freely switch between the attachment / detachment of the squeeze roll 6 and the drive of the device by operating the operation lever 11. Although the drawing shows the state where the squeezing rolls are in pressure contact with each other while the device is being driven, the stopper 25
The stopper 25 is placed so that the bending point formed by the operation link 20 and the intermediate link 19, which are in contact with each other, that is, the pivot fulcrum 21, is located on the guide roll side (mat insertion port side) with respect to the straight line connecting the pivots 18 and 22. It is provided. By doing so, once the squeeze roll is pressed into contact with the operation lever, the pivot point 21 is fixed unless the squeeze roll is released by the operation lever again, and the squeeze roll does not naturally separate due to vibration or the like.

The structure in which the roll moves up and down according to the thickness of the mat is
Not only the squeezing roll but also the guide roll has the same structure as shown in the figure. That is, the bearing rotation link 26 that supports the rotation shaft 4-a of the upper guide roll is supported at a fixed position on the main body side by the pivot 28, and is further urged by the spring 27 in the direction in which the guide rolls are pressed against each other. There is.

Next, the vertical movement of the squeeze roll will be described with reference to FIG.

When the relatively thick mat A is inserted, a force for pushing up the upper squeezing roll is generated due to the thickness thereof. Along with that, the bearing link 13 that supports the rotary shaft of the drawing roll 13
However, it rotates about the pivot point 18 by an amount corresponding to the thickness of the mat. In this case, the pivot point 21 is in contact with the stopper 25, and unless the operation lever is operated as described above, the intermediate link and the operation link are fixed, so the pivot point 18 acts as a fixed support point. And further,
The fulcrum guide 14 and the fulcrum 17 on the main body side fitted to the fulcrum guide guide the movement of the bearing link and determine the rotation range thereof. Further, since the vertical movement due to the thickness of the mat is absorbed by the bearing link and is not transmitted to the intermediate link and the operation link, it does not affect the control switch or the operation lever.

Next, FIG. 4 is an explanatory view showing a state in which the squeeze rolls are separated.

When the operation lever 11 extending out of the apparatus main body is tilted to the mat insertion opening side, the operation link 20 directly connected to the lever rotates until it abuts the stopper 29. Along with that, the intermediate link 19
The bearing link is pulled up around the fulcrum 17 via. At this time, the pivot point 21 is separated from the stopper 25,
Since the intermediate link and the operation link are not fixed, the fixed fulcrum of the bearing link moves to the fulcrum 17 on the main body side. Then,
The urging force of the spring, which has been acting to press the upper squeezing roll downward until then, acts in the direction of assisting the rotation of the bearing link about the fulcrum 17 this time. Therefore, if a force is applied at the initial stage of the operation of the operation lever, then the action of the spring hardly requires the operation force, and the squeeze roll can be separated and the apparatus can be stopped.

The present invention is not limited to the cleaning device of the type in which cleaning water is ejected for cleaning, but can also be applied to a vacuum type device having a suction device.

[Effect of the Invention] The present invention is configured as described above, and has the following effects.

Since the operation lever for switching the drive of the device and the attachment / detachment of the squeeze roll and the bearing link supporting the rotary shaft of the squeeze roll are not directly connected, but are connected via the intermediate link while having a swing function, the mat to be cleaned The vertical movement of the drawing roll due to the thickness can be completely absorbed by the bearing link. Therefore, there is no influence that the movement is transmitted to the operation lever and the lever is vibrated, and the control switch of the device that opens and closes in conjunction with the movement of the operation lever is not affected. Therefore, even if you wash a relatively thick mat,
It is not necessary to open the control switch and stop the device due to its thickness unlike the conventional device.

Also, when the operation lever is operated, the intermediate link serves to switch the squeeze roll from the detached state to the driven state with a light operating force.
