Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle transport conveyor that lifts and transports the front or rear wheels of a vehicle from the floor.

This type of conventional vehicle transfer conveyor has a structure in which the carrier that lifts and supports one wheel axle and the carrier drive chain always maintain engagement and do not separate, so the carrier must be stopped in order to load or unload the vehicle. In this case, it is necessary to stop the drive chain, which significantly reduces the transfer efficiency, and there is also the disadvantage that the vehicle cannot be separated from the drive chain for storage.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the conventional technology, and furthermore, it is possible to transfer even on a curved transfer path with a sharp curve.
Another object of the present invention is to provide a vehicle transfer conveyor that does not have any protruding objects on the floor that obstruct passage on the floor in the non-transfer section from the unloading position to the loading position.

Embodiments of the present invention will be described below with reference to the drawings.

The conveyor of the present invention is installed in an underfloor pit provided along a circulation transfer path 1 as shown in FIG.
In the vehicle transfer section from the loading position 2 to the unloading position 3, pores 5 having a width smaller than the width of the automobile tire are provided in the floor plate 4 covering the pit, but in the non-transfer section, the pores 5 are not provided.

Figures 2 to 4 show the state of vehicle transfer in the transfer section, in which a carrier rail 7 at the same height as the floor plate 4 and a chain rail 8 parallel to this are provided in the pit 6, and in the non-transfer section, both rails are installed. Rails 7a and 8a connected to rails 7 and 8 are connected to rails 7 and 8.
Provide it sufficiently deeper than 8. Rails 7, 8 and rail 7
a and 8a are connected near the loading position 2 and the unloading position 3, and the connection structure will be described later.

Rails 7, 7a, 8, 8a are all opposite 1
The carrier rail 7 is made of a pair of channel materials, and the carrier rail 7 has four rollers 9 and a running carrier 10a.
10b, 10c, 10d, 10e are connected by rod 11
A and 11b run a carrier coupling body 12 which is connected so as to be able to bend left and right, up and down. The carrier coupling body 12 is longer than the entire length of the vehicle M to be transferred, and when the front wheel shaft 13 of the vehicle M is lifted and supported by the carrier 10b, the carrier coupling body 12 protrudes from the front and rear of the vehicle M, and the carrier 10c extends forward of the rear wheels. Located in For this purpose, for example carrier 1
The center spacing between 0c, 10d, and 10e is carrier 10.
The length of the connecting rods 11a, 11b may be determined to be approximately 1/2 of the center spacing between the connecting rods 11a, 10c, and 10c. Although the connecting rod 11b is exposed on the carrier rail 7, the connecting rod 11b is sunk between a pair of channel members constituting the carrier rail 7 so as not to interfere with the lateral deflection of the rear wheels of the automobile on the curved path.

The carrier 10b has a vertical shaft 14 fixed thereto.
, a support member 1 that lifts and supports the front wheel shaft portion 13 is provided.
5 is horizontally rotatable, and the member 15 has a horizontal member 17 longer than the width of the pore 5 fixed to the upper end of a rotating shaft 16 that fits into the vertical shaft 14, and is attached to the upper surface of both ends of the horizontal member 17. The front wheel shaft portion 13 is supported by the attached pad 18. The horizontal member 17 is biased so as to be always perpendicular to the longitudinal direction of the carrier by a pair of springs 19 that attract the front and rear ends of the rotation shaft 16.

The drive chain 20 runs guided by rollers on the chain rail 8, and a removable engagement device 21 is provided between the chain 20 and the leading carrier 10a. The engagement device 21 may be of a known structure, and the fifth engagement device 21 may be of a known structure.
The engagement device shown in the figure consists of a pusher 22 provided on the carrier 10a and a hook 23 provided on the chain 20 that can be raised and lowered. When engaged with the pusher 22, the carrier coupling body 12 is towed and transferred, and when the front slope 26 of the hook metal fitting 23 hits the release piece 27 provided on the rear carrier 10e of the preceding carrier coupling body or a similar fixed position stopper. , the hook fitting 23 is inverted, the engagement is released, and the carrier coupling body 12 is stopped.

The engagement device shown in FIG. 6 is provided with a pusher 28 on the chain 20, and a pusher 28 on the carrier 10a.
A dog device 31 including a pusher dog 29 and a retainer dog 30 that engage with the holder 8 and an engagement holding fitting 32 are pivotally supported on the carrier 10a, and the dog device 31 is pushed down by the weight of the engagement holding fitting 32 to push the pusher dog 29. 28, and when the engagement holding fitting 32 hits a release piece 33 or a stopper provided on the rear carrier 10e of the preceding carrier connection body and tilts upward, the dog device 31 also rises and is released from the engagement.

In the automobile M, the front wheel shaft portion 13 is lifted by the carrier coupling body 12, and the rear wheels roll on the floor surface to be transported.
In a curved transfer path, as shown in FIG.
5 runs on the inside of the curved transfer path. Therefore, the rear wheel rolling area on the outside of the curved transfer path becomes small.

Next, a method for lifting and supporting the front wheel shaft portion 13 using the support member 15 will be described. As described above, the rails 7, 8 and the rails 7a, 8a have a step at the loading position 2 and the unloading position 3, and an example of the connection is shown in FIGS. 8 and 9. At loading position 2 and unloading position 3, carrier rails 7, 7a
are connected by the inclined rail 7b, and the chain rails 8, 8a are connected by the inclined rail 7b at the loading position 2.
Biased rail 8 that extends from the front of b to the front
b, and at the unloading position 3, it is connected by an inclined rail that does not deviate to the side.

Inside the pit at the loading position 2, there is a slat conveyor 36 for transporting automobiles whose loading surface is at the same height as the floor plate 4, and a slat conveyor 36 that runs synchronously with the slat conveyor 36 in a transfer section corresponding to the biased rail 8b to carry the carrier linkage 12. A chain feeder 37 for transferring and a reciprocating type feeder 38 for feeding the carrier coupling body 12 from the rail 7a to the chain feeder 37 are provided. Chain feeder 37 and feeder 38 are carrier 10
It engages with the downwardly protruding pusher 39 of c to transfer the carrier coupling body 12.

The carrier coupling body 12 stops once the engagement holding fitting 32 is tilted upward by the tilting stopper 40 provided at the end of the rail 7a, and when the automobile M is carried into the loading position 2 by the slat conveyor 36,
The detection signal lowers the tilting stopper 40,
The carrier link 12 is launched by means of a feeder 38. The pushing piece of the feeder 38 that engages with the pusher 39 extends forward and pushes the carrier coupling body 12 to a position where the pushing piece of the chain feeder 37 can engage the pusher 39. Thereafter, the carrier coupling body 12 is transferred by the chain feeder 37, and the carrier 10b travels on the inclined rail 7b in synchronization with the front wheel shaft 13 of the automobile M on the slat conveyor 36, while the horizontal member 17 moves forward. It emerges from the hole 41 in the floorboard 4 onto the floor and lifts up the front wheel axle 13. As a result, the automobile M is pushed by the chain feeder 37 with its front wheels raised from the floor surface, and when the leading carrier 10a reaches the rail 8, it is taken over by the chain 20 and transferred.

At the unloading position 3, the carrier 10b moves down the inclined rail so that the front wheels land on the floor.

The present invention has the above-mentioned configuration, and since it is sufficient to provide two stages of carrier rails and drive chain rails in the pit, construction and assembly of the transfer path are easy, and the carrier coupling body is removably engaged. Since the drive chain is engaged by the coupling device, it is possible to load and unload vehicles without stopping the drive chain, which significantly improves the transfer efficiency compared to conventional methods. Also, since the part of the connecting rod of the carrier coupling body that is immediately behind the rear wheels of the car being transported is submerged below the floor surface, the rear wheels of the car on the curved transport path are The inner deflection is free, and the radius of curvature of the curved transfer path can be reduced.
