DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller conveyor and a car washing machine for washing a vehicle while transporting the vehicle on the roller conveyor.

[0002]

2. Description of the Related Art Conventionally, as this type of roller conveyor, there is one shown in FIGS. 10 and 11, for example. That is, between the pair of left and right conveyor frames 61, a plurality of rollers 62 are respectively supported by the support shafts 63 and are attached so as to be freely rotatable.
A sprocket 64 is provided at one end of the rollers 62, and a chain 66 is wound between the sprockets 64 located at both ends of the transport path 65. The upper movement path portion 67 of the chain 66 meshes with the upper portion of the sprocket 64 located in the middle portion, and the lower movement path portion 68 of the chain 66 meshes with the lower portion of the sprocket 64 located in the middle portion. In addition, the transport path 65
The sprocket 64 located at the end (a) of the above is interlocked with the support shaft 63 via a key (not shown). A motor 69 is interlockingly connected to the support shaft 63.

According to this, when the motor 69 is driven to rotate, the support shaft 63 rotates, and the roller 62 located at the end (a) of the conveying path 65 rotates together with the sprocket 64. The rotation of the sprocket 64 causes the chain 66 to rotate, so that the remaining sprocket 64 rotates and the remaining rollers rotate.
62 also rotates in the same direction. As a result, the article is conveyed through the conveyance path 65.
Is conveyed from the start end side to the end (a) side.

[0004]

However, in the above-mentioned conventional type, when the roller conveyor 70 is installed on the floor surface 70 outdoors, the lower movement path portion 68 of the chain 66 approaches the floor surface 70, so that the floor Foreign matter such as sand and water accumulated on the surface 70 adhered to the lower movement path portion 68 and caused a trouble. In order to solve this problem, it is conceivable to set the level of the lower movement path portion 68 to be higher than the floor surface 70, but this makes the overall height of the roller conveyor 70 extremely high, requiring a high installation space. .

Further, a car washing machine using a vehicle carrier is disclosed in, for example, Japanese Patent Laid-Open No. 3-90456. That is, the car wash device body is installed on the floor,
Inside the body of the car wash device, the wheel on one side of the vehicle to be washed acts.
Vehicle transfer device for transferring the object to be cleaned vehicles from entering the mouth to the outlet Te is installed.

The above-described vehicle transport apparatus includes a first sprocket provided on the entrance side, a second sprocket provided on the exit side, a motor for rotationally driving the second sprocket, and first and second sprocket wheels. The chain wound between the sprockets, the vehicle transport roller disposed at a constant interval on the chain and rotatably abutting on the wheel of the vehicle to be washed to advance the washed vehicle, and the vehicle transport roller are the second. Before the vehicle reaches the sprocket, the roller storage means for storing the vehicle transfer roller below the floor surface and the vehicle transfer roller move.
It is arranged on the side of the wheel guide part to prevent wheel loss.
It is equipped with a tire guide and the like.

According to this, one of the washing vehicles is installed in the wheel guideway.

However, the tire width varies depending on the size of the vehicle.
It is difficult to change the tire guide each time.
Yes, there is no choice but to deal with an intermediate width.

◎. If the tire guide has an intermediate width,
When a vehicle with narrow tires is moved forward,
Move the wheel to the left or right, and in some cases the wheel may
Sometimes it jumps out of the id. Also wheel cap
May be injured by collision or contact with the tire guide
is there.

◎. Fix the tire guide in the middle width
This means that you cannot wash a vehicle with wide wheels.
Therefore, the car wash target vehicles are limited. ◎. If the vehicle washing device fails, the car to be washed during the car wash
Both need to be advanced, but in this case
When moving forward, be sure to move over the vehicle transport rollers.
This is not possible and cannot be done easily.

◎. Incorrect side due to driver habits
When the brakes are applied, the rear wheels will lock and rotate.
Since there is no vehicle to be cleaned in the front,
For example, when the vehicle to be cleaned is colliding,
Place a rear wheel that is injured or locked on the floor
To cause the rear wheels to wear while sliding forward while sliding
Become.

Further, the vehicle to be cleaned is temporarily stopped from moving forward.
And then move forward again, the following problems
Dots occur. ◎. For a certain part of the vehicle to be washed whose forward movement was once stopped
Water spray nozzle and top blow nozzle are fixed
During the time (discontinuation time), it is supposed to act locally and wash.
It is not possible to perform a suitable car wash due to uneven cleaning.

The present invention solves the above-mentioned problems, and can prevent foreign matters such as sand and water on the floor from adhering to the lower moving path portion of the endless rotating body while lowering the overall height of the conveyor, and We provide roller conveyors that can be easily installed and car wash machines that use roller conveyors .

[0022]

According to the structure of the first aspect of the present invention, the rotation drive device drives the support shaft at one end of the transport path to rotate in one direction, and the wheel at one end also rotates in one direction. As a result, the endless rotating body rotates and the ring body at the other end rotates to one side, and the ring body at the intermediate portion rotates to the other due to the movement of the lower movement path portion of the endless rotating body, and the roller at the intermediate portion rotates. Rotates to the other. At this time, since the roller at the one end of the transport path and the support shaft are in an edge-cutting state, the roller at the one end does not rotate together with the support shaft, but is moved by the transmission device to the other in the same direction as the roller in the middle part. Rotate. As a result, all of the rollers rotate to the other side, so that the article is conveyed from the start end side to the end side along the conveyance path.

According to this, since the lower movement path portion of the endless rotary body is located above the intermediate wheel body, when the roller conveyor is installed on the floor surface outdoors, the lower movement path portion moves from the floor surface. Since it is located at a high level, foreign matter such as sand and water accumulated on the floor surface is prevented from adhering to the lower movement path portion, and the overall height of the roller conveyor can be made low.

According to the structure of the second aspect of the present invention, since the end ring body and the intermediate ring body are the sprockets and the endless rotating body is the chain, the sprockets and the chain mesh with each other to reliably rotate and drive.

Further, when the intermediate roller rotates to the other side, the rotational force supplying sprocket rotates to the other side and the sub chain rotates, so that the end roller rotating sprocket rotates to the other side. As a result, the roller at one end of the transport path also rotates to the other end, so that the article is transported from the start end side to the end side along the transport path.

Then, the end of the roller conveyor was reached.
The vehicle to be washed is transported further rearward, at which time the wheels are
Since it remains locked, the wash that completed the car wash
The clean vehicle will not run on its own due to the inclination at the exit,
No steep situation occurs. Then unlock the wheel lock
Thus, the vehicle to be cleaned can be moved forward.

Further, the forward movement of the vehicle to be cleaned is once stopped.
Since it can be performed continuously without

Is it possible to wash the car continuously without moving forward
To the vehicle to be cleaned.
There is no local action such as low nozzle, so cleaning is not uneven
A good car wash can always be performed without causing throat
You.

Especially when the rear wheel of the vehicle to be cleaned is locked
If the front wheels are transported by
Roller, it can be rotated on the floor after being sent from the conveyor.
As a result, the front wheels of the vehicle
With the rear wheel on the surface and the rear wheel on the roller conveyor side
Can be stopped. So, for example, immediately turn the handle to the right
Or leave the car in a left-turned state, that is, leave the car
The space outside the exit is small
Can be installed anywhere.

According to the fourth aspect of the present invention, since the end ring body and the intermediate ring body are the sprockets and the endless rotating body is the chain, the sprockets and the chains mesh with each other to reliably rotate and drive. Similarly, since the transmission is formed by the sprocket for rotating the end rollers, the sprocket for supplying the rotational force, and the auxiliary chain, the sprocket and the auxiliary chain are meshed with each other and reliably rotated. As a result, the driving force can be reliably transmitted to each roller, and even a heavy object such as a vehicle to be cleaned can be sufficiently conveyed.
