Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rocker brush device for a car washer used to operate a rocker brush in a car washer.

2. Description of the Related Art A conventional car washing machine is provided with a pair of left and right arms swingable around a vertical axis in a car washing machine body as shown in, for example, Japanese Utility Model Publication No. 61-34917, and the free ends of these arms are provided. A lower side surface cleaning brush (rocker brush) is attached via a brush shaft, and a brush driving motor is provided in each arm. By swinging the arm, both lower side surface cleaning brushes are configured to be movable toward and away from each other, and by the approaching movement, the lower half of the vehicle body including the wheels is cleaned from the rocker.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above conventional type, the brush bristles of the rocker brush spread at right angles to the brush shaft axis center due to the rotational centrifugal force of the brush shaft, but when viewed in a plan view, the soft bristles of the brush bristles are loose. It is bent so that its end is on the rear side of rotation, that is, it is wound around the brush shaft. Further, as shown in FIG. 8, the wheel has a corner portion formed by the rim 36 and the wheel cap 37.
38 is formed in the shape of a step toward the inside.

Therefore, when the wheel is washed with the rocker brush as described above, the circular corner portion 38, especially the front and rear circular arc portions 38a facing each other at a right angle to the rotation direction 39 of the brush bristles is insufficiently washed. Becomes That is, by contacting the rocker brush to the rim 36 and the wheel cap 37,
The contact pressure causes the bristles to easily bend to the rear side of rotation, making it difficult for the bristles to enter the front and rear arc portions 38a, resulting in insufficient cleaning. The upper and lower arc portions of the front and rear arc portions 38a and above are opposed to each other in a direction parallel to the rotation direction 39 of the brush bristles, so that the brush bristles can easily enter and sufficient cleaning can be performed.

The above-mentioned difficulty in entering the front and rear arc portions 38a can be solved by adopting a round brush with hard bristles, but in this case, the tire 40, the rim 3
6, It is easy to damage the wheel cap 37 etc.

An object of the present invention is to provide a rocker brush device for a car wash machine that can sufficiently wash the entire area of a wheel even if soft and long bristles are adopted.

Means for Solving the Problems In order to achieve the above object, a rocker brush device for a car wash machine according to the present invention is provided with a pair of left and right holding frames in a car wash body so as to be close to and away from each other, and these holding frames have a left-right axis. An arm and an oscillating device that are swingable around a center are provided, and the arm is provided with a rocker brush and a rotator that are rotatable about a rotation axis that is orthogonal to the horizontal axis.

According to the configuration of the present invention, the two rocker brushes are moved toward each other in a state in which the rocker brush by the rotating device is rotated about the rotation axis, so that the rocker brush of the vehicle body including the outer surface of the wheel is moved. Normal cleaning can be performed by contacting the lower half. Then, while the rocker brush is in contact with the outer surface of the wheel, the rocker brush is oscillated around the axis in the left-right direction via the arm while the relative movement between the car wash body and the car is stopped or slightly accelerated. By moving the rocker brush, it is possible to displace, in the circumferential direction around the axis of the left-right direction, a portion of insufficient cleaning generated at a position facing at right angles to the rotation direction of the rocker brush. Regular cleaning can be performed over this period.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 7.

The gate-type car washer body 1 has a rail 3 through a plurality of wheels 2
It is located above and can be reciprocally traveled on a fixed route by the operation of a travel drive device (not shown). The car wash body 1 includes a first wash water arch 4 and a first wax arch 5.
And a second wash water arch 6, a second wax arch 7,
A detergent arch 8 is arranged in this order, and a top nozzle 9 and a side nozzle 10 for drying are provided at the location of the first washing water arch 4, and the top brush 11 and the side brush 12 are respectively swingable. It is attached via various arms 13 and 14.

Rocker brushes 15 are provided at the lower portions on both sides of the car wash machine body 1 so that they can move toward and away from each other. That is, an L-shaped holding frame 16 is arranged in a front view, and the holding frame 16 is supported on the car wash machine body 1 side by a pair of left and right links 17 or the like, so that the holding frame 16 can swing left and right while maintaining its posture. In addition to the above, a cylinder device 18 for swinging is provided between the link 17 and the car wash machine body 1. The horizontal frame portion of the holding frame 16 supports a horizontal shaft 20 that is rotatable around a horizontal axis 19, and the horizontal shaft 20 is held by a transmission device 21 arranged in the vertical frame portion. The swinging device 22 provided on the frame 16 is interlockingly connected. The rocking device 22 is composed of an electric motor, a cylinder device, and the like.

A right-angled bent arm 23 is attached to the inner end of the horizontal shaft 20, and the arm 23 is swingable around a horizontal axis 19. Further, at the inner end of the arm 23, a rotary shaft (vertical axis) 25 which is rotatable around a rotary shaft center 24 orthogonal to the left-right direction shaft center 19 is attached, and the rotary shaft 25 is integrated with the brush shaft. Then, the rocker brush 15 is attached. The rotating shaft 25 is linked via a transmission device 26 to a rotating device (electric motor or the like) 27 provided on the arm 23. The reference numeral 30 designates an automobile, and its wheels 31 are wheel caps 32 and rims.
It consists of 33 and tires 34. 28 indicates an operation panel.

In the above-described embodiment, the automobile 30 is stopped and the car wash machine body 1 is reciprocated while the brushes 11, 12 and 15 are moved in and out of contact with each other, the wash water is supplied through the wash water arms 4 and 6, and the wax A desired car wash can be performed by appropriately operating a combination of supplying wax through the arches 5 and 7 and supplying detergent through the detergent arch 8.

At this time, the abutment movement of the rocker brush 15 causes the cylinder device 18 to extend from the separated state as shown in FIG.
The holding frame 16 can be moved inwardly without disturbing its posture, so that the rocker brush 15 is brought into contact with the outer surface of the rocker portion of the vehicle body as shown in FIGS. 2 to 4. It is possible to wash the wheel cap 32, the rim 33, and the like at the same time by contacting and washing them, and then bringing them into contact with the outer side surface of the wheel 31, while washing the lower half of the vehicle body.
