Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a car wash machine of a type in which a vehicle is introduced into a tunnel-shaped car wash unit that surrounds the vehicle, and the car is washed while moving. In particular, the present invention relates to a vehicle transport device that moves a vehicle in synchronization with a car wash operation.

[Prior Art and Its Problems] Conventionally, the structure of a vehicle conveyance device in a fixed type device for a car wash machine has been as shown in FIGS. 8 and 9. The configuration shown in Figure 8 consists of two
A chain 42 equipped with wheel pressing rollers 43 is attached to two sprockets 40 and 41 at regular intervals, and after the wheel has entered the conveyance starting point, the rollers 43 are set on the wheel by rotating the sprocket, and the chain 42 is pushed to the end point. , with respect to the vehicle transport direction from the transport start point to the end point, the trajectory in the reverse direction from the end point to the start point is located directly below. This method has the problem that the roller tracks are vertical in the vehicle transport direction and in the reversing direction, so it is necessary to dig into the installation surface from the transport start point to the end point, which requires labor and increases costs. There is.

On the other hand, in FIG. 9, although the installation surface is partially dug, it is a horizontal type in which the tracks of the rollers in the vehicle transport direction and the reverse direction are on the same plane, so there is no need to dig the transport path from the start point to the end point. Therefore, installation work is relatively easy,
It is characterized by low cost.

However, with this configuration, when the wheels reach the conveyance end point,
Since the roller 43 pushes out the wheel while wrapping around the sprocket 41, the roller and the wheel transmit pressing force while changing from line contact to point contact, as shown in FIG. At that time, the point of contact between the roller and the wheel moves to the tip of the roller, and the load is applied to one point. As a result, an excessive rotational moment acts on the connection between the roller and the chain, causing problems such as the chain floating in relation to the sprocket, causing teeth to jump, and causing the chain to stretch, resulting in accidents when the chain comes off. .

[Object of the invention] The present invention has been made to address the above-mentioned problems.
Easy to install and low cost, rollers for vehicle transport °
The purpose is to provide a safe vehicle transport system that does not apply unnatural force or overload to the connection between the chain and the chain.

[Means for Achieving the Object] In order to achieve the above object, the present invention provides a horizontal device in which a chain equipped with vehicle transport rollers is attached to sprockets at the start and end points of the transport path. A sprocket installed at the end point of the roller that has transported the vehicle up to this point retracts the roller below the transport road surface just before it begins to change direction in the reverse direction, and then rises again to the same surface as the transport road after reversing the direction. It was configured as follows. This allows line contact between the rollers and wheels to be maintained from the start point of the transport path to the end point of vehicle delivery, preventing unnatural force or overload from being applied to the connection between the rollers and the chain, and allowing the vehicle to run smoothly. It is sent to

Next, the vehicle transport means for moving the vehicle in synchronization with the progress of the cleaning operation will be explained based on FIG. 2. The vehicle conveyance means 24 is arranged on the vehicle conveyance roadbed surface of the tunnel type frame 1.
It is laid continuously from the entrance to the exit. Reference numeral 26 denotes a first sprocket fixed horizontally on the floor of the frame inlet, and 27 denotes a second sprocket installed on the floor of the frame outlet at the same height as the °l-th sprocket. A chain 28 is a power transmission means, and vehicle conveyance rollers 29 are provided at regular intervals to transmit power to the cleaning vehicle. Reference numeral 30 indicates a wheel guide path, and reference numeral 36 indicates a tire guide, which is driven by a motor 33 which is driven in response to a signal to start a car wash and applies rotational force to the second sprocket, and which prevents wheels from coming off. As shown in FIG. 3, the first and second sprockets have their rotating shafts and mechanical parts that receive rotational force from the motor 30 located at a lower position than the floor surface, and the chains are placed on the vehicle transport road surface. Only the driving part is made to protrude. Therefore,
There is a rail 2 on the floor with a height corresponding to the thickness of these two sprockets and the width of the chain 28 that hangs thereon.

Point a is located between the left and right wheels of the cleaning vehicle and is closest to the bottom of the vehicle. Therefore, by laying only the chain drive part on the floor, clearance with the bottom of the vehicle is secured, and when laying the chain, it is necessary to It is possible to significantly reduce the number of parts to be stored underneath, making installation work easier.

On the other hand, the vehicle conveyance roller attached to the chain protrudes from the rail 2/La side in the center of the vehicle toward the wheel side, and consists of two cylindrical rollers that are rotatable with respect to the wheels and a roller that connects the rollers and the chain. It consists of a fixed bracket and an arm for attachment to the chain.

The detailed configuration will be explained based on FIG. 4.

The roller fixing bracket 29d has a "he" shape, and
Among the rollers, the cylindrical roller 29a that directly contacts the wheels of the cleaning vehicle has its center axis fixed at the top point of the "he" shape, and the remaining cylindrical roller 29b is the cylindrical roller 29a that is in direct contact with the wheels of the cleaning vehicle. Fix the center shaft at the rear lower side of the The entire fixed bracket 29d including the two rollers is attached to the chain via the arm 29f. Note that the arm 29f is not immovably fixed to the chain, and is in a positional relationship parallel to the chain when the roller is on the wheel guide path 33, but as shown by the chain line in FIG. When separated from the guide path 33, the attachment is supported so as to be rotatable within a range of 90 degrees about the fulcrum 29c.

Reference numeral 31 denotes a transport roller storage opening/closing plate provided on the same plane as the wheel guide path 33, and 32 an opening auxiliary roller rotatably attached to the opening/closing side tip of the transport roller storage opening/closing plate. As shown in FIG. 2, this opening auxiliary roller 32 faces on the movement trajectory of the roller fixing bracket 29d on the vehicle transport roller 29, and when the vehicle transport roller reaches this position as shown in FIG. It ascends along the inclined part 29e of the fixed bracket and opens the transport roller storage opening/closing plate 31.

Then, as explained in FIG. 4, the arm 29f is rotated and stored in the space of the roller storage means 34, and the vehicle conveyance roller 29 leaves the wheel guide path 33. Thereafter, the vehicle conveyance roller reverses its moving direction at the second sprocket 2Y and heads toward the first sprocket, that is, the frame 1 population side. The vehicle conveyance roller whose moving direction has been reversed returns to a state parallel to the chain along the ascending slope 36 (see FIG. 2) on the opposite side of the conveyance roller storage opening/closing plate 31 across the rail 24a.

Next, the operation from the approach of the cleaning vehicle to the sending out is explained in 1.2.
．． This will be explained based on FIG. First, the cleaning vehicle A enters the vehicle entry guideway 25 and the front wheels A-1 are placed on the wheel guideway 33. In this case, the front wheel shall ride inside the frame from the first sprocket 26, and
6 is located between the front wheels A-1 and the rear wheels A-2, and the vehicle is temporarily stopped.

Next, the start switch is operated to drive the vehicle conveyance means. Then, the chain begins to move and the nearest vehicle conveyance roller 29 comes into contact with the front wheel A-1, and the vehicle A-1 continues to move.
move forward at a constant speed. When the leading end of the vehicle A that has been transported inside the frame and has finished cleaning reaches the exit of the frame, the transport roller storage means plate 31 is opened and the vehicle transport roller 29 that was pressing the front wheel A-1 is released. It is stored in the space of the roller storage means 34. Then, as shown in Fig. 7, the vehicle that has lost the pressing force stops moving forward when its front wheels are at position B, and at that point the next vehicle transport roller 29° located at a distance of 1 from the rear wheel A-2 moves forward. It will stop temporarily until it hits the rear wheel. When the vehicle conveyance roller 29° comes into contact with the rear wheel, the vehicle A starts moving forward again, and this time, with the rear wheel as a reference, the vehicle A is subjected to a pressing force to a position B and is pushed out of the frame. By configuring like this,
The installation length of the vehicle transport means can be shortened by L, and can be kept within one dimension of the frame.
