Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a cargo lifting and reversing device for reversing as necessary, and more specifically, a cargo such as a fruit box sent from a conveyor onto a gondola is transferred upward by a tension of a rope, and is moved to a desired position above the cargo. The present invention relates to a device for reversing a gondola to drop a cargo from the gondola and transferring the cargo to a destination.

[0002]

2. Description of the Related Art Conventionally, as a device for transferring cargo upward, a cargo is placed on a wagon and the wagon is manually transported.

Further, as a device for lifting a cargo, a crane having a movable boom which is a columnar structure that supports a load through a pulley, a rope, a crane hook, etc. and changes a working radius by ups and downs, expansion and contraction, and bending. Exists.
The movement of cargo by this crane is limited to the vertical direction by the hoisting chain or the horizontal direction by the movable boom.

[0004]

However, the former one of those described in the above-mentioned prior art is uneconomical because it requires time and labor, and the workability is deteriorated. There was a problem.

In the latter case, a wide space is required to mount a trolley, a cab containing a power machine and a controller, and a factory having a high ceiling sufficient for raising and lowering the boom is required. In addition, there is a problem that the workability is poor because the work of attaching and detaching the cargo is done manually.

Therefore, in order to eliminate the problems described in the prior art, the present invention tilts the conveyor so as to descend toward the lower part of the supporting column, and the gondola slides down the sliding groove of the supporting column. When the cargo is located in the lower position, the cargo moves on the gondola by accelerating on the sloping conveyor, and after the movement, the rope winding motion of the winder pulls the gondola upward to move it to the gondola. A part of the attached rollers slides in the guide groove to reverse the gondola forward and send the cargo loaded on the gondola to another place to save space, load and lift the cargo. The purpose is to improve unloading workability.

[0007]

In order to achieve the above object, in a cargo hoisting and reversing device of the present invention, columns having sliding grooves on opposite inner side surfaces are erected on the left and right sides and installed in parallel with the sliding grooves. The guide grooves are attached to the pillars, and the rollers are rotatably attached to the side portions of the gondola provided with the holding portions.
Each of the rollers is slidably mounted in each of the sliding groove and the guide groove, a lower end of a rope hanging from above is attached to the gondola, and the gondola is vertically and inversely moved by tightening and tightening the rope. A technical means is provided in the lower part of the support column, a conveyor inclined so as to descend toward the support column, and a stopper which is moved up and down in correspondence with the positional relationship of the gondola.

[0008]

The gondola has a function of pressing the stopper by its pressing portion by its own weight to position the stopper below the conveyor. Since the conveyor is gently inclined so as to descend toward the pillar, cargo is accelerated on the conveyor and transferred onto the gondola located at the lowest position. When the rope is tensioned after the transfer, the rollers of the gondola slide in the sliding groove and guide groove respectively due to the pulling force of the rope.
The gondola rises, but when the rollers sliding inside the guide yard slide on the curved part of the guide groove, the gondola reverses forward and the loaded cargo falls from the gondola and is sent to the next destination. .

While the gondola is rising, the stopper is released from the pressurizing action of the gondola, is positioned above the conveyor, locks the cargo transferred by the acceleration motion on the inclined conveyor, and lowers the gondola. Waiting for
