Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a presser mechanism for a squeezing roll in an automobile mat washer, and is characterized in that it facilitates lifting of the presser roll and attachment/detachment of the squeezing roll. It is.

(Prior Art) An automobile mat washing machine is used to wash floor mats installed in the interior of an automobile, and is composed of a guide roll, a brush, and a squeezing roll. The squeezing roll squeezes out water droplets adhering to the pine, and consists of a receiving roll and a presser roll. The presser roll is applied with a pressing force, and is pressed against the receiving roll with an appropriate force. I'm starting to do that.

This squeezing roll is made of open-cell foam with appropriate elasticity, such as polyurethane resin foam, and after use, water is trapped in the bubbles, so this water freezes in the winter. The roll solidifies,
Further, there is a problem in that the upper and lower rolls are joined together, making it impossible to carry out the next cleaning operation. For this reason, matte washing machines have conventionally been configured so that the presser roll can be raised and lowered, and in the winter, when washing is completed, the presser roll is pulled up slightly to cut off contact with the receiving roll.

By the way, as mentioned above, the squeezing roll is made of open-cell foam and wears out faster than the guide roll, so it often needs to be removed from the machine for repair. However, as mentioned above, the conventional pine washer has a mechanism that applies pressing force to the presser roll and a mechanism that pulls it up, making it extremely troublesome to remove the squeezing roll. This impairs the practicality of the matte washing machine.

(Means for Solving the Problems) The present invention uses a presser foot piece to apply and raise the pressing force of the presser roll, and also makes it extremely easy to attach and detach the presser roll. When the roll is pulled up, the presser foot is moved out of the attachment/detachment path of the receiving roll, making it easy to attach and detach it.

(Examples) Hereinafter, the present invention will be specifically described based on illustrated examples.

In the figure, 1 is a guide roll, 2 is a rotating brush, 3
4 is a receiving roll, and 4 is a presser roll. These are the same as ordinary ones of this kind, and when an automobile mat is inserted between the upper and lower guide rolls 1,
The mat is drawn into the machine at a constant speed by a guide roll 1, brushed, and then passes between a receiving roll 3 and a presser roll 4, where water droplets adhering to it are squeezed out and discharged into the machine. It's summery.

The receiving roll 3 and the presser roll 4 are so-called squeezing rolls, and are formed using an open cell material having appropriate elasticity, such as polyurethane resin foam. The receiving roll 3 and presser roll 4 are detachably attached to the machine body, and the presser roll 4 is in pressure contact with the receiving roll 3 with an appropriate pressing force, so that an automobile mat caught between them can be held in place. Bearings 5 and 6 are installed at both ends of the roll shaft of the receiving roll 3 and at both ends of the roll shaft of the presser roll 4, while bearings 5 and 6 are installed on both sides of the machine body. is equipped with a side plate 7 and a mounting groove 8 in this side plate 7.
The receiving roll 3 and presser roll 4 are attached to the side plate 7 by fitting respective bearings 5 and 6 into attachment grooves 8. The upper end of the mounting groove 8 is open, and the bearings 5 and 6 can be fitted into the mounting groove 8 from this open end and removed from the open end.

A presser piece 10 is attached to the outer surface of the side plate 7, and a handle 15 is also attached to the presser piece 10. During work, the presser piece 10 applies a pressing force to the presser roll 4 and presses it against the receiving roll 3, and after the work, it is pulled up and separated from the receiving roll 3 to prevent the presser roll 4 and receiving roll 3 from freezing. The handle 15 allows the presser foot 10 to be operated with a small amount of force. First, the presser piece 10 will be explained. This piece includes a presser part 11 that presses the bearing 6 of the presser roll 4, a lifting rod 12 that pulls up the bearing 6, and an engaging pin 1 that will be described later.
3 and an engaging protrusion 14 that engages with the mounting groove 8, the base end of which is rotatably mounted slightly rearward of the open end of the mounting groove 8. In addition, the handle 15 is connected to the presser foot 1.
An engagement pin 13 is rotatably attached to the lower part of the handle 1 and protrudes to engage with the upper edge of the presser part 11 and the front edge of the engagement protrusion 14.
A coil spring 16 is stretched between one point P of the body (the figure shows an example in which the engagement pin 13 is projected outward and attached thereto) and one point P of the body. This attachment point P is located at the presser foot 10 when the handle 15 is pulled down as shown in FIG.
Attachment point Q of the handle 15 to the handle 15
When the handle 15 is pushed down backwards as shown in FIG. It is provided at a position behind the line passing through the dowel pin 13. The lifting rod 12 can only be rotated counterclockwise from the position shown in the figure, and when removing the receiving roll 3, first move the handle 15 backward as shown in Figure 1B. The holding roll 4 is removed by pushing it down, and then the lifting rod 12 is pushed upward to pull out the receiving roll 3 from the mounting groove 8. The presser foot 10, the handle 15, and the coil spring 16 are attached symmetrically to the left and right side plates, and a connecting rod 9 is passed between the two handles so that they are interlocked. .

(Function) When the handle 15 is tilted forward, the handle 15 rotates clockwise in the figure around point Q by the force of the coil spring 16 to contract. Then, since the engagement pin 13 comes into contact with the upper edge of the presser foot 11, the above-mentioned force is applied to the presser foot 11 via the engagement pin 13, and the attachment point R of the presser foot piece 10 is
is used as a fulcrum, and acts as a force to rotate the presser foot 10 clockwise using the engagement pin 13 as a point of action. Further, this force is applied to the bearing 6 and presses the presser roll 4 against the receiving roll 3.

Of course, in this case, it is desirable that the direction in which the bearing 6 is pushed down corresponds to the groove direction of the mounting groove 8, so that the line connecting the contact point S between the presser part 11 and the bearing 6 and the rotation center R of the presser piece 10 should be It is desirable to determine the position of the center of rotation so as to be perpendicular to the groove direction of the mounting groove 8.

Next, when the handle 15 is pulled up, the handle 1
5 rotates around point Q, and eventually the engagement pin 1
3 comes into contact with the engaging protrusion 14 (see FIG. 1A).
In this state, a force is applied to the handle 15 to rotate it counterclockwise, and the presser foot 1
Since a force is acting on the handle 15 to rotate it clockwise, the handle 15 will stop at this position. When the handle 15 is pushed further backward, the engagement protrusion 14 is pushed by the engagement pin 13, and the presser foot 10 rotates about the R point. Then, the bearing 6 is pulled up by the lifting rod 12, and the presser roll 4 is separated from the receiving roll 3.

(Effects) As described in detail above, the present invention provides an automobile pine washing machine in which bearings are attached to both ends of the squeezing roll consisting of a presser roll and a receiving roll.
This is removably attached by fitting it into the mounting grooves formed on both side plates of the washer, and furthermore, a presser piece is rotatably attached to each side plate, and a handle is rotatably attached to this. A coil spring is installed between the handle and a suitable position on the machine body, and by pulling the handle forward, a pressing force can be applied to the presser roll, and the handle can also be tilted backward. Ba,
The presser roll is pulled up and separated from the receiving roll, and in this state both rolls are free, so even if the moisture contained in the rolls freezes in winter, there is a risk that the two rolls will join together. Since there is no need to worry about this, you can start work at any time, and since it is extremely easy to attach and remove the rolls, it is easy to repair or replace the rolls, so you can always work in the best condition. . or,
Since the handle is rotatably attached to the presser foot and a coil spring is attached to it, it is possible to pull up the presser roll with much less force than when the handle is fixed to the presser foot. It was.
