Abstract

PURPOSE:To prevent an article from being damaged as well as to make a lot of articles alingable in line automatically, by absorbing the inertia force in a way of letting a conveying load collide with a rotatable stopper, while rotating the stopper and thereby making the conveying load travelable, in time of conveying the load on a sloping conveyance passage by means of gravity. CONSTITUTION:A conveyed load 2 rolls on a sloping conveyance passage 1 and collides with a stopper 3. Since the stopper 3 is provided with a shock absorber 4, the conveyed load 2 is absorbed of its inertial force when colliding with the stopper 3. Therefore, the stopper 3 rotates clockwise by dint of gravity on the conveying load, retreating from the surface of the conveyance passage 1 and the conveyed load 2 rolls on the sloping conveyance passage 1 by dint of the gravity. With this constitution, any damage due to collision in time of stoppage of the conveyed load is prevented and, what is more, a lot of conveyed loads can be aligned in line.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of transporting articles using gravity using an inclined transport path.

Means for conveying various articles using gravity include methods of sliding down a conveyance path, methods of rolling down a conveyance path, and conveyors using rollers, balls, etc. to reduce the frictional force on the conveyance path surface. However, when these methods are used, the speed of the transported object gradually increases after it starts running, and especially if the transported object is heavy, the shock it receives when it stops is very strong. Accidents such as damage to transported items often occur.

Therefore, the present invention absorbs the inertia force of the transported object by the stopper 7 while the transported object is traveling on the inclined transport path due to its own gravity, and also uses this stopper to The above-mentioned problem is completely solved by lifting the object onto the path by gravity and allowing the object to continue traveling, and at the same time correcting the orientation of the object with respect to the transport path and completing the transport. The purpose of the present invention is to provide a transport method that can automatically align objects to be transported at any time. .

The conveying method of the present invention will be explained below with reference to illustrated embodiments.

First, in FIGS. 1 to 3, a conveyed object 2 is placed on an inclined conveying path 1, and is caused to roll and travel by its own gravity. In this case, the object 2 to be transported is a cylindrical object, and while it is traveling, the object 2 to be transported collides with a stopper 3 rotatably arranged on the transport path 1. Since the stopper 3 is associated with the buffer 4, the inertia force of the conveyed object 2 that collides with the stopper 3 is absorbed by the buffer 4. Due to this collision action, the cyst collar 3 is rotated in the tense direction in the figure by the gravity of the object 2 to be transported, and is removed from the path of the object 2 to be transported.

Therefore, the object 2 to be transported can travel to the next stopper position by its own gravity without being hindered by the stopper 3. .

In this way, by absorbing the inertial force of the transported object 2 at any time during the traveling stage, the speed of the transported object 2 is prevented from increasing more than necessary, and the impact caused by the collision between the transported objects 2 at the final stop position is prevented. This means that the force can be reduced. 7. Thus, a plurality of pairs of stoppers 3 are arranged on the left and right sides of the conveyance path 2 at predetermined intervals in the length direction of the conveyance path 2. In this manner, by providing the stoppers 3 on the left and right sides, the unreasonable inclination of the conveyed objects with respect to the conveyance path that tends to occur during traveling is corrected, and the conveyed objects 2 can be correctly aligned and stopped.

In the illustrated case, the conveyance path 1 is composed of a pair of left and right rails la and 'l'b provided at a distance, and left and right stoppers 3 are attached to a support shaft 5 horizontally suspended between the rails la and lb. The upper part of both stoppers 3 protrudes from both rails la and lb 1, while the shock absorber 4
The above two stoppers 3 are installed on the front side of the position, that is,
This shock absorber 4 is provided in the upper part of the conveyance path 1, and is rotatable by having its base 4a pivotally fixed to a support shaft 6 that extends horizontally between both rails 1a and 1b. The tip is rotatably connected to a connecting rod 8 that connects the lower ends of both stoppers 3. Therefore, when the object 2 to be transported collides with the stopper 3, the stopper 3 is pushed by the object 2 to rotate, and the inertial force of the object 2 to be transported can be temporarily absorbed by the buffer 4. In addition, stopper 3 and buffer 4
Of course, the left and right stoppers 3 can be connected via a link mechanism, and although the left and right stoppers 3 are shown in the figure as rod-shaped, it is also possible to form the left and right stoppers integrally into a frame shape. Alternatively, the present invention can be practiced even if the plate is formed in the shape of a top plate.

Next, we will explain an example of transporting an object that is not itself transferred. In this case, as shown in Fig. 4, the left and right frame frames 1
The present invention is carried out by supporting a roller 12 between the rollers 1a and 1a, and constructing an inclined conveyance path 11 by arranging the rollers 12 in parallel, and causing the object to be conveyed 2' to run on this conveyance path by gravity. do.

In the case of this embodiment as well, the structures of the stopper and the buffer are the same as those shown in FIGS. 1 to 3 above, so the same reference numerals are used and the explanation thereof will be omitted.

The present invention is as described above, and since the inertia of the conveyed object traveling by gravity is absorbed at any time, the traveling speed is reliably regulated from increasing more than necessary, and when the object is finally stopped, It reduces the impact force and eliminates the risk of damage, and by arranging stoppers on both the left and right sides so that the transported object collides with them, the transport path of the transported object, which is likely to occur while driving, is eliminated. It is possible to correct an unreasonable inclination to the object, and it is also possible to automatically align objects to be transported, which is particularly effective for automatic transport work over long distances. In addition, by adjusting the distance between stoppers, the strength of the buffer, the inclination angle of the conveyance path, etc., it is possible to arbitrarily control the conveyance speed of the conveyed object. This is a revolutionary method for transporting various items by gravity, as it saves labor, and its practical value is extremely great.

Claims (1)

[Claims] While the conveyed object is traveling on an inclined conveyance path due to its own gravity, it collides with a rotatable stopper that has a buffer function to temporarily absorb the inertial force of the conveyed object. At the same time, the stopper is rotated by the gravity of the object to be transported, and this rotation removes the stopper from the path of the object to continue traveling the object. , J.
