Abstract

PROBLEM TO BE SOLVED: There are many stoppers of a conventional roller conveyor, and there are some that can only be placed. However, a horizontal member is arranged on two or three roller conveyors, and the vertical is perpendicular to the tip of the horizontal member. There is a member, the upper part of the member receives the load and the lower part hits the side of the roller to exert a stopper effect, but it requires 2 to 3 installation space, and the amount of material and weight are also large And the cost will increase.
SOLUTION: Since it can be installed simply by passing between adjacent rollers between a pair of roller conveyor frames, the installation area is small and the material can be manufactured with little.

Description

The present invention relates to a stopper that holds a box-shaped baggage on a roller conveyor at an arbitrary position in a roller conveyor that is used mainly by temporarily, temporarily increasing / decreasing, moving, moving and removing, and connecting a single unit or a plurality of units. .
Conventional roller conveyors are one form of usage where a gentle downward slope is desirable in the transport direction, but especially in agricultural fields, there are many sloping fields, and even seemingly flat fields have a gentle slope, local high low and adjacent There are irregularities on the ground, and the upward and downward gradients in the transport direction appear remarkably on each linked roller conveyor, and it is difficult to forcibly correct the gradient, and there are cases where the upward and downward gradients remain mixed on each conveyor. There are many.
The original purpose of use of the roller conveyor under the above conditions is to carry plastic boxes and cardboard boxes and to use any upper surface of the roller conveyor as a workbench, and the purpose of use of the stopper is to carry the load If you want to keep it at the end of the conveyor, prevent falling from the beginning of the conveyor on the loading side, if you want to keep the box at any position on the conveyor and pack it on the roller conveyor as a work table, etc. However, there is a demand for a plurality of stoppers to simply hold the load, although the worker who loads the boxes loaded on the conveyor waits on its own and puts it on hold, and there is a demand for multiple stoppers. Most of them are fixed types, and some are just placed, but they are installed by occupying three rollers on the opposite side of the cargo transport direction. Product is large heavy in weight, use a lot of area on or a roller conveyor, when installing the end, there is a luggage stops drawbacks roller 3 duty away from both the final end.

The first problem is to have a structure that exerts a stopper function only by placing it in an arbitrary narrow space without using fixing means.
The second problem is to reduce the stopper installation area and keep the area of the roller conveyor upper surface large.

The first and second problem solving means is to place the stopper installation place between any adjacent rollers in a bridged state on the conveyor frame and receive the force acting on the stopper at four points, especially the stopper configuration. This was solved as a structure using the reaction force of the force that the main horizontal member of the member lifts the bottom of the load.

It is lightweight, has a small installation area, and effectively exhibits a stopper effect. Only the vertically upper member protrudes above the roller top surface in the stopper component, and the amount of reduction in the area of the roller top surface of this member is extremely small .
Since it can be installed between one roller at the end of the roller conveyor and two rollers in front of it, the effective area of the upper surface of the conveyor is less reduced due to the installation at both ends of the roller conveyor, and since the width of the roller conveyor is constant, When expressed in terms of length, the roller arrangement pitch is reduced by only a little less than one pitch, and multiple installations can be easily performed in the middle of the roller conveyor. In this case, the installation area per stopper is reduced only by the thickness of the vertical member. It is a decrease.

The side view of the partial cross section which shows the positional relationship of the stopper of this invention, a roller conveyor, and a load 1 is a cross-sectional view taken along the line AA in FIG. The side view which shows the state just before a box hits a stopper in the enlarged view of the part enclosed by the dotted circle B in FIG. FIG. 2 is an enlarged view of a portion surrounded by a dotted circle B in FIG. 1, and a side view showing a state in which the box hits the stopper and the stopper functions effectively. Side view of a stopper with an auxiliary horizontal member added to the stopper of the present invention The top view of the stopper which added the auxiliary horizontal member to the stopper of this invention

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
S is an upper surface RFU of the frame RF of a pair of roller conveyors R, which is a stopper, and is installed by simply placing it between any adjacent rollers RR, and an angle bar having a cross-sectional shape similar to that of angle iron is the parent body. Are divided into a vertical upper member SVU that contacts the front surface of the package BOX and a main horizontal member SH1 that enters the bottom of the package.
The vertical lower member SVD is a member that extends downwardly between the left and right frames RF on the vertical upper member SVU. The vertical lower member SVD hits a line at the side Z of the roller RR, and the angle bar angle that becomes the base material when the stopper is activated. Is in linear contact with the frame upper surface RFU of the roller conveyor R, and the contact point is denoted as Y1.
When the load BOX hits the stopper S, that is, the vertical upper member SVU, the vertical member SV is slightly inclined around the Y1 point, and the load BOX is in contact with the vertical upper member SVU at the X point of the front lower end corner of the load. At the same time, the vertical lower member SVD comes into contact with the Z point on the side surface of the roller RR, and the tip W of the main horizontal member SH1 comes into contact with the bottom surface of the load. Demonstrate the effect.
The above-described stopper shape is insufficient in effect. In particular, when the inclination of the vertical member SV becomes large, such as when the main horizontal member SH1 cannot sufficiently enter the bottom surface of the load or when the load hits very strongly, W The force to hold the point is small and the stopper S gets over the roller.
An auxiliary horizontal member SH2 is arranged on the opposite side of the main horizontal member SH1 so as to extend to the pair of frame upper surfaces RFU. The point distance is increased and the inclination of the vertical member SV is prevented from increasing, the stopper S is prevented from getting over the roller, and the stopper effect is exhibited.
