Description

The present invention relates to a ball caster unit that replaces a plurality of adjacent rollers, which adds a function of freely changing the conveyance direction of a box to be conveyed to an arbitrary location selected on a roller conveyor.

Trucks and tractors that are used for farming work, especially boxes that are packed with harvested items in the field, and are carried out of the field and kept on farm roads and work roads (commonly referred to as boom roads, hereinafter referred to as boom roads). A method of carrying around a large container (commonly called a bucket, hereinafter referred to as a bucket) provided at the rear, a method of carrying around by a worker, a method of carrying a certain amount on a transport cart that is moved by human power or power, a roller conveyor There is a method of arranging the slabs directly on the field and carrying them out while repeating the transfer of the roller conveyor.

The method of arranging the roller conveyors directly on the field is a heavy burden of frequent relocation work, and some producers have purchased the conveyor but do not use it. A structure / mechanism has been proposed in which the trolley can be pushed and moved by manpower along the ridge groove, and a method of connecting a plurality of conveyors and easily moving them has started to spread.

When using the above-mentioned moving type roller conveyor, there is a request to change the flow of conveyance, as many as about 90 degrees, as in the factory.
Separately, it is manually transferred to a roller conveyor arranged in a substantially right angle direction, but one person is required, and it is an unsuitable work for those who are weak due to heavy labor.
There is an example that introduced a ball caster type turning machine equipped with four commercially available legs and a turning function, but its installation is difficult due to its heavy weight and a lot of problems. It is.
If the direction change function can be used easily, the direction change work will be light work and even a powerless person will be possible, and if a direction change guide plate can be installed to change the flow direction, One person can be reduced.

Selection on the size of the roller conveyor is determined by the bottom size of the transported box to be transported.
In addition, the roller conveyor uses a lot of products produced and sold with standard dimensions.
The standard length of the roller conveyor (generally called the captain, hereinafter referred to as the captain) is 1 meter, 1.5 meters, 2 meters, 3 meters,
The standard width of the roller conveyor (generally referred to as machine width, hereinafter referred to as machine width) is 305 mm, 360 mm, 460 mm, 560 mm, 660 mm, etc.
Generally, the machine width is selected based on the short side dimension of the bottom surface of the transported box, and the machine length and the number of roller conveyors are determined based on the carry-out distance.

  An object of the present invention is to propose a mechanism that can easily add a direction changing function to any desired position on a roller conveyor in a roller conveyor that is used singly or in combination.

A structure in which a ball caster unit is incorporated at a position where a plurality of adjacent rollers at selected positions on a roller conveyor are removed, and when the ball caster unit is assembled, the roller conveyor main frames are connected in parallel to each other between the main frames. If the main stay and the stay pipe that keep the inner dimensions and displacement of the inner pipe and the stay pipe connecting long bolt interfere with each other, remove them.
The main frame of the ball caster unit has the functions of the main stay of the roller conveyor and the stay pipe connecting long bolt.

The ball caster unit is composed of a ball caster unit main frame, the ball caster unit main frame fixing bolt, a number of ball casters and the ball caster fixing bolt,
The ball caster unit main frame is formed into two ears by bending both ends of the flat plate in the same upward direction into a flat bar shape, and the shape is divided into the ball caster main frame plane portion of the remaining plane portion,
The ear is along the roller conveyor main frame, and is fixed to the roller conveyor main frame by using a roller shaft support hole of the roller conveyor main frame with the ball caster main frame fixing bolt.
A large number of ball casters are regularly arranged on the plane portion of the main frame of the ball caster unit, and are fixed by the ball caster fixing bolts.
The length of the ball caster unit is set to a length corresponding to the long side length of the bottom surface of the transported box, and the rollers adjacent to the front and rear end portions of the ball caster unit are not in contact with each other.

The surface formed by the apex of the ball caster incorporated in the ball caster unit and the surface formed by the apex of the roller incorporated in the roller conveyor are substantially the same surface.

The installation position of the ball caster unit can be freely selected at one or a plurality of selected positions of the roller conveyor used alone or in combination.

The ball caster unit of the present invention can be incorporated as a retrofit at any selected position of a roller conveyor that is used alone or in combination.
Installation position adjustment, height adjustment, tilt adjustment, instability adjustment for 4 legs, and on-site transfer, relocation, movement, unloading, etc. that occur when using a ball caster direction change machine of another standard Is unnecessary.

It can also be incorporated at a plurality of selected positions on the roller conveyor.

It can also be incorporated into the connecting part of two roller conveyors. For example, if a ball caster unit with a length ½ of the required unit length is installed at each end of the roller conveyor connecting part, the direction change function is also applied to the connecting part. Can be added.

  As described above, the ball caster unit of the present invention can easily and inexpensively add to the roller conveyor a function that sufficiently compensates for the defects of the ball caster direction changing machine of another standard.

The ball caster unit of the present invention is a schematic plan view in which five rollers at selected positions on a roller conveyor are removed, and the main stay and stay pipe provided on the roller conveyor and the stay pipe connecting long bolt are described. FIG. It is a schematic side view of FIG. It is a schematic sectional drawing in the arrow AA of FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
