[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention is mainly used in automobile production factories to perform work such as spraying anti-rust wax under the floor of finished cars and inspection. The present invention relates to a vehicle transport device.

(Prior Art) Generally, in an automobile production factory, work such as spraying anti-slip wax onto the underfloor of a completed vehicle that comes off an assembly line and inspecting the floor of the vehicle are performed. In order to perform such underfloor work on a vehicle, a vehicle conveyance device is provided that uses a pair of intermittent pallet conveyors on the left and right sides to support and convey the left and right front and left wheels of the vehicle from below.

In other words, FIGS. 4 and 5 show a conveying device for conveying completed automobiles 1 one after another onto a groove-shaped bit 2.
Intermittent pallet conveyors 3.degree. 3 are arranged in parallel in the longitudinal direction on the left and right sides of the bit 2, respectively. This pair of left and right intermittent pallet conveyors 3.3 has an endless O-ra chain 6 attached to a pair of upper and lower sprockets 4.5 that are pivotally supported near the start end and near the end (not shown) in the bit 2. The pallets 7 for front wheels and the pallets 8 for rear wheels are attached alternately to each roller chain 6 at a predetermined interval in the longitudinal direction, and the left and right conveyors 3.3 are rotating parts! They are rotated in synchronization with each other by an IJ device (not shown). The front wheel pallet 7 has a recessed portion on its upper surface, and the rear wheel pallet 8 has a flat upper surface. In addition, 9 in the figure is a support frame for the conveyor 3, 10.11 is an upper outbound guide rail of the conveyor,
Reference numerals 12 and 13 indicate a lower return guide rail of the conveyor, and 14 a conveyor cover, and all of these components are arranged to face each other on the left and right sides.

Then, the left and right front and rear wheels 1a, 1t) of the automobile 1 are placed and supported on the front wheel pallet 7 and the rear wheel pallet 8 of the left and right intermittent pallet conveyor 3.3, and in this state, the left and right conveyor 3.3 rotates. By doing so, the vehicle 1 is conveyed from one end on the bit 2 to the other end. A robot 16 equipped with a paint gun installed on the work floor 15 midway inside the bit 2 sprays anticorrosion wax onto the underfloor of the automobile 1 being transported in this manner.

Here, in the above-mentioned vehicle conveyance device, in order to facilitate the work under the floor of the automobile, the left and right intermittent pallet conveyors 3.3 are provided with pallets other than the pallets 7.8 that support the left and right front and rear wheels 1a and Ib of the automobile 1. is open to the public. Therefore, as it is, it is impossible for the automobile 1 to get on or off the left and right conveyors 3, 3 by self-propelled operation because the wheels will come off. For this purpose, a transfer means is required for loading the automobile 1 from one end of the left and right conveyor 3.3 and removing it from the other end.

Conventionally, as the transfer means, a travel lifter 17 is provided as shown in FIG. This traveling lifter 1
7 is a motor 19 provided on the truck frame 18. Deceleration 20
The pinion 21 is rotated and reciprocated along a traveling rail 22 having a rack (not shown), and the support plate 25 at the upper end is It has a structure that moves up and down.

The traveling lifter 17 runs on its own in a narrow bit area a (narrower than the distance between the left and right wheels of the car 1) at one end of the bit 2 and stops there, and then runs over the bit area 2a and stops there. The support plate 2 is moved by the drive of the lift cylinder 23.
5 rises and lifts. The traveling lifter 17 lifts the car 1 while moving the left and right conveyor 3 on the bit 2 side.
3, and there, the support plate 25 is lowered to place the left and right front and rear wheels 1a, 1b of the automobile 1 on the front and rear wheel pallets 7.8 of the left and right intermittent pallet conveyors 3, 3. and transfer it.

Although not shown, a travel lifter similar to that described above is also provided on the other end side of the left and right intermittent pallet conveyors 3.3, and the vehicle 1 is lifted off from above the conveyors 3, 3, and the vehicle 1 is moved directly to the narrow bit section. transport it to the ground and lower it to the ground.

(Problems to be Solved by the Invention) By the way, the above-mentioned conventional vehicle conveyance device uses a unique traveling drive device and a lifting drive device as means for transferring the vehicle 1 to the left and right intermittent pallet conveyors 3.3. Since the traveling lifter 17 having *i configuration is provided, the installation cost and operating cost are high, and the traveling lifter 17 requires a considerable amount of maintenance.

In addition, since the travel lifter 17 reciprocates in a predetermined cycle and picks up the car from a fixed location and transfers it, the driver is required to be very strict about the stopping position and timing of the car. It becomes hard work.

Moreover, the vehicle is transferred by such a traveling lifter 17 (
Handling is unstable and there is a risk of falling, so it is necessary to be careful, and the car transfer cycle time is correspondingly long.In other words, the traveling lifter 17 lifts one car and transports it, and the left and right conveyors 3.3 It takes a long time to transfer cars to the top and come back, making it impossible to transfer cars one after another efficiently. In other words, it is not possible to improve the efficiency of transporting vehicles by the left and right conveyors 3.3, which results in a decrease in the efficiency of working under the floor of the vehicle.

The present invention was developed in view of the above circumstances, and allows the driver to directly touch the intermittent pallet conveyor on the left and right sides while driving the car, without using anything like a conventional traveling lifter. We provide an extremely advantageous vehicle transport device that allows users to get on and off the vehicle, improves the efficiency of vehicle transportation and underfloor work, is simple in configuration, reduces equipment costs and expenses, and is less prone to breakdowns and easier to maintain. The purpose is to

[Structure of the invention]

(Means for Solving the Problem) In order to achieve the above object, the vehicle conveyance device of the present invention provides a starting end of a left and right intermittent pallet conveyor having a pallet on which the left and right front and rear wheels of a four-wheeled vehicle such as an automobile are placed and supported. The present invention is characterized in that short slat conveyors are provided in the vehicle transfer zones on the side and the end side, respectively, so as to fill the spaces between the respective pallets, and rotate and move in synchronization with the intermittent pallet conveyor.

(Function) With the above configuration, if a car is driven directly into the vehicle transfer zone on the starting end side of the left and right intermittent pallet conveyors, its left and right front and rear wheels will compensate for the pallet mutual space of the left and right intermittent pallet conveyors. In this state, you can ride on the slat conveyor that is rotating synchronously, and from there you can safely ride on each pallet on the left and right intermittent pallet conveyors, and the pallets will be conveyed as they are. Once the vehicle has been transported to the vehicle transfer zone on the side, if the vehicle is allowed to run on its own, the left and right front and rear wheels will be on the slat conveyor, which is rotating synchronously with each pallet filling the space between each pallet on the left and right intermittent pallet conveyors.

Furthermore, a car landing plate 40 is provided on the upper surface of the end of the transfer zone between the starting end and the ending end (not shown) of the bit 2.

When the left and right intermittent pallet conveyors 3.3 are driven to rotate, the slat conveyors 30 installed in the transfer zones on the starting end side and the ending end side are rotated in synchronization with each other. As a result, a large number of slats 34 of the slat conveyor 30 run in parallel (i4) on the upper outbound path, filling the space between each pallet 7.8 of the left and right intermittent pallet conveyor 3.3.

In this state, if the vehicle 1 is driven forward from above the boarding board 4o at the end of the vehicle transfer zone on the starting end side, and is allowed to run on its own, directly entering onto the left and right intermittent pallet conveyors 3°3.
The left and right front and rear wheels 1a and 1b of the automobile 1 rotate synchronously with each pallet 7.8 of the left and right intermittent pallet conveyor 3.8 without falling out of the mutual space and filling the space. Slat 34
3. Climb onto the left and right intermittent pallet conveyors.
It becomes possible to safely get onto the front wheel pallet 7 and the rear wheel pallet 8 of No. 3.

The car 1 that has been boarded in this way has its left and right front and rear wheels 1a and 1b supported by the front wheel pallet 7 and the rear wheel pallet 8 of the left and right intermittent pallet conveyor 3.3.
By the rotational movement of 3, the parts are separated from the top of the slat conveyor 30 and transported to the work zone of bits 2, and during the transport, under-floor work such as spraying anti-corrosion wax is performed by a robot equipped with a painting gun, as in the past. become.

Further, when the automobile 1 is worked under the floor and is transported to the vehicle transfer zone at the terminal end of the left and right intermittent pallet conveyors 3.3, the automobile 1 is driven forward as it is and is allowed to travel on its own. Now that automatic l! 1, the left and right front and rear wheels 1a and 1b are transferred on the slat conveyor that rotates synchronously in a state where each pallet 7.8 of the left and right intermittent pallet conveyors 3, 3 is filled in the same way as on the starting end side, and the pallets are safely removed. You will be able to go to the ground from the boarding board.

Note that the present invention is not limited to the above embodiments,
For example, in addition to painting the underfloor of finished cars on the above-mentioned automobile production line, it can be used for other underfloor work on automobiles, or in addition to automobiles, four-wheeled vehicles such as various transportation carts can be used to improve the production of containers, panels for prefabricated houses, etc. It can also be used for transporting vehicles.
