Description

Single Post Vehicle Transfer Lift Using Combined Bearings

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single-post type vehicle transportation lift using a combined bearing, and instead of omitting one of the loaded car and the rail guiding the shanghai east of the cargo, the combined bearing (Combined Bearing) By reducing the width of the parking facilities by installing the), it is possible to increase the amount of parking on the same site, increase the utilization of the parking space, while allowing the cargo to move smoothly, and reduce the factor of trouble.

A vehicle stacker type elevator is one of the components of a parking facility using an automatic warehouse method. The automatic warehouse generally includes a rack for storing and storing a vehicle, a stacker type elevator for entering and exiting a vehicle from the rack, and controlling the same. Controllers (sequencers and computers).

The stacker-type elevator takes over the vehicle from the storage cart and stores it in the rack indicated. In addition, when a release instruction is issued according to a schedule instruction from a computer, the vehicle is extracted from the rack indicated and delivered to the release trolley.

The stacker-type elevator includes a cargo, a pulley installed on an upper portion of the cargo, a hoisting rope which is wound around the pulley to rotate the pulley, and lifts the cargo, a motor that winds and unwinds the hoisting rope to change its length, Two post frames for guiding movement from the left and right of the cargo, and a movable body provided with a horizontal movement of the entire elevator and the two post frames are provided on the driving wheel side and the driven wheel side, respectively.

Conventional vehicle lifts are almost impossible to load so that the center of gravity of the cargo coincides with the center of gravity of the vehicle when the vehicle is mounted on the cargo. T-rails and H-types fixed to the driven wheel-side post frames and box-shaped drive wheel-side post frames of the H-beams by installing four or five rollers in the middle of the cargo side, respectively. The rollers are guided by rails.

However, in the conventional case, in addition to installing a roller for preventing the front and rear fall of the cargo on both sides of the cargo, a separate roller is inserted between the cargo and the rail to prevent the cargo from being left and right pulled. By adopting the formula, the width of the entire elevator, that is, the width of the cargo, plus the length corresponding to the diameter of the roller, plus two frames to support the lifting of the cargo, are used to efficiently land the land on the limited parking space. It was difficult to use it, and there were problems such as limited parking capacity.

The present invention devised to solve the above problems, the use of the parking space by adding a mechanism that can absorb the moment of inertia and moment formed during the driving of the cargo to one post frame for supporting the cargo containing the vehicle The purpose of the present invention is to provide a lift for transporting the cargo while allowing the cargo to move smoothly and to reduce the frequency of failures.

For this purpose, it is possible to absorb the inertia force and moment caused by the cargo by mounting a combined bearing which has a single post frame that supports the lifting operation of the cargo and simultaneously rolls the inner side and the inner bottom of the single post. As can be solved by the present invention, it will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a plan view of the present invention, and FIG. 2 shows a front view of the present invention.

The present invention, in the stacker-type elevator consisting of a cargo, pulley, hoisting rope, post frame, and a movable body, H-shaped single post (4) with c-shaped rails attached to both sides of the box structure for supporting the lifting action of the cargo (5) And two radial rollers (2) (2 ') which roll and roll the inner side of the single post (4), and are attached and rotated inside the respective radial rollers (2) (2'). There are two thrust rollers (3) (3 ') and the like which rolls through the inner bottom of the single post (4), and the radial rollers (2) (2') and the thrust rollers (3) (3 ') are combined. The combined bearing 1 which is formed is fixed to one each of the upper and lower sides of the side of the cargo 5, and is configured.

Hereinafter, the operation of the single-post type vehicle transportation elevator using the combined bearing of the present invention will be described in detail.

When a wear or release command is issued from a control device (sequencer and computer) which is one of the components of the stacker type elevator of the present invention, the driving wheel of the movable body driving the stacker type elevator is driven to move to the starting point of the command.

The stacker-type elevator is then operated to reach the target parking row and then to the destination floor of the parking space, whereby the hoisting rope 8 between the motor (not shown) and the pulley 9 is released or wound so that the cargo 5 is To reach the floor.

When a vehicle is mounted inside the cargo 5, only one side of the cargo 5 is supported and guided to the single post 4, so that a phenomenon occurs in the other side of the cargo 5 which is not supported by the remaining post frame. Done.

And, since the center of gravity of the vehicle mounted on the cargo 5 rarely coincides with the center of gravity of the cargo 5, the cargo 5 will be inclined to either side and if not corrected, the entrance of the cargo 5 The point where the entrance to the parking space (not shown) of the target floor meets will not match.

In addition, the degree of inconsistency and moment of the center of gravity becomes larger as the cargo 5 starts to ascend, which causes a significant shear load on the single post 4.

Therefore, the combined bearing 1 attached to the upper and lower portions of the sidewalls of the cargo 5 smoothly rolls the single post 4 while moving the cargo 5 in the shanghai. The entrances of the seals (not shown) coincide with each other so that the vehicle can be moved safely.

The radial rollers (2) and (2 ') of the combined bearing (1) roll the inner wall of the single post (4), but the rotational axes of the two radial rollers (2) and (2') are on the same line. The thrust rollers 3 and 3 ′ of the combined bearing 1 are also located on the same line to roll the inner side wall and the bottom of the single post 4.

In this way, the combined bearing 1 carries a radial roller 2 supporting moments due to the inertia force of the cargo 5 acting in the vertical traveling direction and the unloading of the cargo 5 in the traveling direction, and traveling. The cargo 5 in the direction perpendicular to the direction is compactly configured with a thrust roller 3 which prevents the fall (or pull) due to the unloading load, thereby simplifying the overall elevator machine structure.

The vehicle transport elevator of the present invention is compactly composed of a radial roller and a thrust roller of the combined bearing, which can simplify the elevator machine structure, thereby simplifying the fabrication and installation of the elevator, thereby reducing the cost and increasing the frequency of failure. Reduction in equipment reliability is greatly improved, and the overall machine width is also reduced, which allows more parking in a narrow space.

In addition, by operating a mechanical parking facility, a lot of parking is possible on the same site, or a small number of sites are required for the same number of parking lot, which is very good for business.

In addition, when the driving space on the driven side is somewhat insufficient due to the terrain, the device of the present invention is conveniently applied to facilitate layout configuration, and can be extended to a stacker crane of a warehouse.
