Description

DETAILED DESCRIPTION OF THE INVENTION A1 Object of the Invention (1) Industrial Application Field The present invention relates to a vehicle transfer method for transferring a vehicle between a slat conveyor and a trolley on which the vehicle is loaded and transported; and relating to a vehicle carrier directly used for carrying out the method.

(2) Conventional technology In order to transfer a vehicle between a pair of left and right slat conveyors that support the wheels of the vehicle and a trolley-type conveyor that supports the bottom of the vehicle, it is disclosed, for example, in Japanese Patent Laid-Open No. 59-227503. When using a trolley like the one shown in the figure, this can be achieved either by providing a transport path for the trolley in the center of the left and right slat conveyors and raising and lowering the entire trolley including the supporting members, or by raising and lowering the supporting members relative to the trolley. It is possible to separate or seat the wheels of a vehicle supported on a support member with respect to a slat conveyor (Japanese Patent Laid-Open No. 59-227503
(see publication).

(3) Problems to be Solved by the Invention However, in the conventional system described above, the supporting member of the trolley supports the center part of the bottom of the vehicle, so the support of the vehicle is unstable and it is safe for workers to get into the vehicle interior. It was difficult to work on.

The present invention has been made in view of the above-mentioned circumstances, and provides a method for transferring a vehicle to and from a slat conveyor while supporting the vehicle in a stable state, and a method for directly using the method. The purpose is to provide a vehicle transport trolley.

B0 Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, the vehicle transfer method of the present invention includes:
A vehicle transfer method in which the vehicle is mutually transferred between a pair of left and right slat conveyors that support and convey the wheels of the vehicle and a trolley that runs on a conveyance path arranged parallel to the slat conveyors. To transfer the vehicle from the slat conveyor to the truck, the left and right support members provided on the truck are closed inside the slat conveyor, and the support members are positioned between the conveyance surface of the slat conveyor and the bottom surface of the vehicle. This is done by opening the support member above the slat conveyor and then raising it, and bringing the support member into contact with the vicinity of the left and right side sills of the vehicle to separate the wheels of the vehicle from the slat conveyor. After the vehicle wheels are seated on the slat conveyor by lowering the supporting members that support the vicinity of the left and right side sills of the vehicle between the transport surface of the slat conveyor and the bottom surface of the vehicle, the supporting members are moved inside the slat conveyor. It is characterized in that it is performed by closing.

Further, the vehicle transport trolley of the present invention runs on a transport path arranged in parallel between a pair of left and right slat conveyors that support and transport the wheels of the vehicle, and transfers vehicles between them and the slat conveyors. This is a vehicle transport trolley, in which rotary shafts are arranged in the vertical direction on the left and right sides of a base that can be raised and lowered, and a support member for the vehicle is provided at the other end of a support arm whose one end is fixed to the rotary shaft, and the drive source The support member is selectively positioned between a position below a side sill of the vehicle and a position inside the left and right slat conveyors by rotationally driving the rotating shaft. In addition, the said base may be raised and lowered for each trolley|bogie, and only the base may be raised and lowered with respect to the trolley|bogie.

(2) Function According to the vehicle transfer method described above, the cart is positioned below the vehicle with the support member closed inward so as not to interfere with the slat conveyor or the wheels of the vehicle loaded on the top of the slat conveyor. After that, the support member is opened outward and then raised.

Then, the vehicle whose side sill vicinity is pressed by the support member is pushed upward from the slat conveyor and transferred to the trolley. Conversely, the vehicle is transferred from the truck to the slat conveyor by lowering the truck, seating the wheels of the vehicle on the left and right slat conveyors, and then closing the support member inside the slat conveyor. This allows the vehicles on the slat conveyor to move without interfering with the support members of the carts.

Further, according to the vehicle transport trolley of the present invention, a rotating shaft to which a support arm having a support member at the tip is fixed is vertically disposed on a base that moves up and down integrally with the trolley or relative to the trolley. By rotationally driving this rotating shaft with a drive source, the supporting member moves between a position below the side sill of the vehicle and a position inside the left and right slat conveyors.

(3) Examples Hereinafter, the present invention will be described in detail based on the drawings.

An elevating platform 5 supported by two left and right links 2.3 pivoted at A connectable lifting rail 6' is provided.

A conveyance path for the truck C is constituted by both rails 6 and 6'.

The trolley C, which runs supported by the fixed rail 6 and the lifting rail 6', is pivoted by three left and right brackets 8 hanging from both sides of a rectangular base 70.
'The main roller 9 rolling on the upper surface and the rail 6.6
A sub-roller 10 for preventing lifting and a sub-roller 11 for preventing derailment are provided, which roll on the inner and outer surfaces of the flange portion of the wheel. A fixed rack par 12 and an elevating rack par 12' are provided on the floor surface and the lifting platform 5 so as to be located between both rails 6.6'. It is driven via a motor 14 and a gear box 15 to make it self-propelled. A band-shaped fixed power supply member 16 and an elevating power supply member 16' are fixed to the upper part of each rack par 12, 12', and a current collector brush 17 hanging from the lower surface of the base 7 is attached to both power supply members 16, 16'. Through sliding contact, power is supplied to the motor 14 and control signals are transmitted. Note that the reference numeral 18 in FIGS. 4 and 5 is a cleaner that comes into sliding contact with the main roller 9 and cleans its outer periphery.

Front and rear support means 19 and rear support means 20 for supporting the vehicle (2) are provided at the front and rear of the base 7 of the truck C. Since the front support means 19 and the rear support means 20 have the same front-back symmetrical structure, the front support means 1 will be described below as a representative.

A pair of left and right rotating shafts 22 are supported on bearing blocks 21 fixed to the left and right sides of the upper surface of the base 7 so as to be rotatable around a vertical axis.A binion 23 and an L-shaped support are attached to the upper end of the 0-rotating shaft 22. The base end of the arm 24 is fixed, and a support member 25 is fixed to the tip of the support arm 24, which can come into contact with the front part of the side sill of the vehicle (2) from below. The support member 25 is made of a rectangular plate, and a stopper 26 for positioning the vehicle V is provided protruding from its outer end.

Guide block 2 provided between left and right bearing blocks 21
A rack member 29 that meshes with the left and right binions 23 at the same time is slidably supported on two guide rails 28 formed on the upper surface of the rack member 7 via a slider 30. It is connected to a rod 33 of a supported cylinder 32 as a driving source and is driven to reciprocate.

Therefore, when the cylinder 32 is extended, the support arm 24 rotates to the solid line position in FIG. The arm 24 rotates to the chain line position and retreats to a position further inside than the inner ends of the left and right slat conveyors S.

Next, the operation of the embodiment of the present invention having the above-described configuration will be explained.

To transfer the vehicle (2) from the slat conveyor S to the cart C, first the vehicle V transported by the slat conveyor S is stopped above the bit P2. At this time,
As shown by the solid line in FIG. 6, the truck V has a zero-order cylinder retracted inside the bit P2 with all four support members 25 of the front support means 19 and the rear support means 20 closed inward. 4, the cart C is raised together with the lifting platform 5 via the links 2 and 3, and the support arm 24 and support member 25 provided on the base 7 of the cart C are connected to the transport surface of the slat conveyor S and the vehicle V. The lifting platform 5 is temporarily stopped so as to be located between the bottom surfaces of the platform. From this state, the cylinder 32 is extended to rotate the support arm 24 fixed to the rotating shaft 22 via the rack member 29 and the pinion 23 outward, and the support member 25 provided at the tip thereof is positioned at the bottom of the side sill of the vehicle V. (See the thick chain line in FIG. 6). When the cart C is further raised together with the lifting platform 5, the support seat 25
(see the thin chain line in FIG. 6), the vehicle (2) moves its wheels W away from the slat conveyor S and completely moves onto the bogie C as shown in FIG.
Translated above.

At this time, the elevating rail 6' laid on the elevating table 5, the elevating rack par 12', and the elevating power supply member 16' are connected to the fixed rail 6, fixed rack par 12, and fixed power supply member 1 laid on the floor.
6 and on which the vehicle V is mounted, the trolley C moves from the platform 5 toward a predetermined location.

Conversely, in order to transfer the vehicle ■ from the cart C to the slat conveyor S, the cart C carrying the vehicle ■ is stopped on the lifting platform 5, and the cart C is moved along with the lifting platform 5 to the bit P! lower inward. Then, the wheels W of the vehicle ■ are connected to the slat conveyor S.
Once seated on the platform, the descending of the platform 5 is temporarily stopped, and all the support members 25 are closed inward so as not to interfere with the slat conveyor S, and then the platform 5 is lowered further and the cart C is retracted into the bit P2. let Therefore, slat conveyor S
The upper vehicle (■) can move freely without interfering with the trolley (C).

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the embodiments described above, and various small design changes may be made without departing from the scope of the present invention as set forth in the claims. It is possible to do so.

For example, in the embodiment, the lifting platform 5 is further lowered from the position where the support member 25 opens and closes, but even if the cart is stopped at the height where the support member 25 opens and closes, the support member 25 can be lowered. When closed inward, interference with the wheels W of the vehicle V is prevented, so the vehicle (2) on the slat conveyor S can be moved freely. Further, in the embodiment, as a means for raising and lowering the support member 25, the trolley C itself is raised and lowered together with the lifting platform 5, but the base 7 on which the support member 25 is provided may be raised and lowered relative to the trolley C. Further, the opening/closing driving means for the support member 25 is not limited to the cylinder 32, and other driving means such as a motor can be used.

C1 Effects of the Invention As described above, according to the vehicle transfer method of the present invention, the supporting member provided on the truck is opened outward and brought into contact with the side sill of the vehicle, so that the vehicle can be kept in a stable state. As a result, work can be easily carried out by getting into the vehicle interior. Moreover, since the support member is stored inside the slat conveyor, the cart and the vehicle can be moved without interfering with each other.

Further, according to the vehicle carrier of the present invention, the support member is provided at the tip of the support arm whose base end is fixed to the rotating shaft connected to the drive source, so that the support member is positioned below the side sill of the vehicle. and the inside position of the slat conveyor.
