Abstract

PURPOSE:To prevent the occurrence of work lock between a chute and an installation and ensure feeding, by a method wherein, in a turning-over and feeding device for a long article, a downslope bent in dogleg-shape is located to the chute, and a stopper is situated to the end part of the downslope board CONSTITUTION:An article A fed over a table 1 is fed on guide panels 4 by meanms of rollers 3, the forward end of the article A is naturally dropped at the forward ends of the guide panels 4, the articel A enters between the guide panels 4 and is placed on a downslope board 5, and is forced into contact with a stopper 6. In which case, the guide panels 4, the downslope board 5, and the stopper 6 are set so that the rear end of the article A is separated from the table 1. This causes the article A to be rocked in a manner that its rear end is turned downward at a bending point B serving as a fulcrum, and is transferred to the chute 2 and is glided down over the chute 2. This constitution enables the article to be reliably turned over and fed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an article feeding device, and particularly to an article feeding device that feeds a long article while reversing its feeding direction.

(Prior Art) When it is necessary to let the above-mentioned article fall naturally onto a chute from a table of manufacturing or other equipment, and then feed it to a predetermined position by sliding it down the chute, conventional techniques have been used. A feeding device constructed as shown in FIG. 4 was used.

In the figure, 1 is a stand and 2 is a shooter.

On the table 1, the article A is fed so as to slide on the surface of the table 1 and be pushed in the direction of the arrow. At the end of the table 1, the article A naturally falls downward from its tip. In the middle of the fall, Shooter 2
It is arranged to be inclined in the opposite direction to the feeding direction on the table 1, and the article A falls onto this chute 2, and then slides down on this chute 2 and is discharged to a predetermined place. I'm going to go.

By the way, in the case where the article naturally falls from the table 1 in such a configuration, there will be no problem as long as the article falls like the article A1 indicated by the chain line and eventually becomes parallel to the chute 2. However, like article A2, the right end is the shooter 2.
If the item A2 falls so that its left end hits the wall IA or other equipment of the stand 1, depending on the angle of the item A2 with respect to the chute 2 and the wall IA, the item A2 may be caught and locked. You may not be able to fall further than that. In such a case, article A2 is no longer
It is no longer possible to discharge the liquid to a predetermined location using the chute 2.

(Problems to be Solved by the Invention) This invention solves the problem that when an article is allowed to fall naturally onto a chute and is fed to a predetermined location, the article is caught between the chute and the equipment and is locked. The purpose is to ensure that this type of product is delivered reliably.

(Means for Solving the Problems) The present invention is characterized in that a slide is provided above the chute and is bent in a dogleg shape with respect to the chute, and a stopper is provided at the end of the slide. .

When an article falls naturally from a platform, the tip of the article lands on the sliding platform at the beginning of the fall. The article placed on the slide naturally slides down the slide with the tip facing down. If the distance between the bending point of the sliding platform and the stopper is selected to be at least half or less of the length of the object, for example, about 1/3 to 1/4, the object will slide down the sliding platform naturally. Then, the article whose tip reaches the stopper and its sliding is stopped, rotates using the bending point as a fulcrum due to its weight balance,
It will run parallel to this above the chute. Once this condition is reached, the article will surely slide down the chute as it is.

During the process of the article falling, the article slides down on the slide, so that the rear end of the article is sufficiently separated from the equipment. Therefore, it is possible to reliably prevent the article from hitting the equipment or the chute and becoming locked as in the prior art. Furthermore, even if the tip rotates about the bending point as a fulcrum before it slides down until it hits the stopper, and as a result the rear end hits the equipment, in this case a rotational force is acting on the item. This will help overcome the frictional force with the equipment or chute. Therefore, even in such a case, the article will not be locked.

This invention will be explained using figures. The article A is fed on the table 1, falls naturally onto the chute 2, and then naturally slides down the chute 2, which is the same as the conventional structure. If one of the tables 1 is driven to rotate by a motor or the like, after the article A is sandwiched between the rollers 3, it will be reliably fed by the rollers. Reference numeral 4 denotes a guide plate for guiding the movement of an article that falls naturally and rotates.

According to this invention, a slide 5 is installed at the upper end of the chute 2 so as to be bent in a dogleg shape relative to the chute 2. A stopper 6 is attached to the tip of the bending table 5.

When the tip of the article A fed on the table 1 gradually moves away from the table 1, the tip becomes heavy and the balance is lost, and the article A naturally falls from the tip due to the weight. The position of the slide 5 is set so that the tip of the tip rests on the slide 5 in the process of falling, so in this state, the article A passes over the slide 5 until its tip reaches the stop. Slide down naturally until you hit 6. As a result of this sliding down, the rear end of the article A becomes separated from equipment such as the table 1 or its wall IA, as shown in FIG.

The length of the slide 5 is set to be less than half the length of the article A, for example, about 1/3 to 1/4 of the length of the article A. Therefore, when you slide down the slide 5 and the tip hits the stopper 6 and stops.

With the bending point B, which is the boundary between the chute 2 and the slide 5, as a fulcrum, it rotates counterclockwise in FIG. 2 depending on the weight balance of the article, and as shown in FIG. Then you will be able to follow it.

During this rotation process, the rear end of the article A does not collide with the wall surface IA at all. Even if a collision were to occur, there is a rotational force acting on article A at this time, and this rotational force would overcome the frictional force between the rear end of article A and wall IA, so that this rotation would not occur. There is no chance that it will lock up and stop midway. The same applies even if the article A starts rotating before its tip hits the stopper 6.

As shown in FIG. 3, the article A placed on the chute 2 then naturally slides down the chute 2. Since the chute 2 is inclined in the opposite direction to the article feeding direction on the table 1, the article A is fed in the opposite direction to the article feeding direction.

In the above explanation, the tip of the article A on the table 1 was explained as falling naturally due to its weight, but the feeding force on the table 1 is increased and the article A flies into the air from the top of the table 1. It may be allowed to fall naturally in this manner. Even in this case, once the tip of the article A is placed on the sliding table 5, the article A will slide down, rotate, and then naturally slide down in the same manner as described above.

(Effects of the Invention) As detailed above, according to the present invention, by simply installing a sliding platform and a stopper in the chute, the articles being fed are locked and fed. What does it mean to be stopped?

This has the effect that it can be reliably avoided.
