Description

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

(Prior Art) When it is necessary to drop the above-mentioned article from a table of manufacturing or other equipment onto a shooter and then feed it to a predetermined position by sliding it down the shooter, 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, a shooter 2 is arranged on the table 1 with an inclination in the direction opposite to the feeding direction, and the article A falls onto this shooter 2, and then slides down on this shooter 2. Then, it will be discharged to a predetermined location.

By the way, in such a configuration, if the article falls naturally from the table 1, there will be no problem as long as it falls like the article A1 indicated by the chain line and eventually becomes parallel to the shooter 2. However, if the article A2 falls so that its right end hits the shooter 2 and its left end hits the wall 1A of the stand 1 or other equipment, the angle of the article A2 with respect to the shooter 2 and the wall 1A may , the article A2 may get caught and locked, making it impossible to drop it any further. In such a case, it is no longer possible to discharge the article A2 to a predetermined location using the shooter 2.

Another method for feeding articles in an inverted manner is to provide a tray in the middle of feeding the articles, and when one article is placed on this tray, the weight of the tray and the article and the balancer are unbalanced. Another structure has been proposed in which the tray is rotated by the action at that time, and the article is discharged in a direction opposite to the previous feeding direction. However, this configuration requires parts that move mechanically, such as the tray and balancer, and also operates according to the weight of the item, so it is necessary to install a balancer for each item for items of different weights. It has to be changed, and it is troublesome to make adjustments for each change.

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

Another object of the present invention is to simplify the configuration and facilitate adjustment without requiring a mechanical movement mechanism to reverse the feeding direction of the article.

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

The tip of the article falling naturally from the platform is placed on the slide 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 slide and the stopper is selected to be at least half the length of the object, for example, 1/3 to 1/4, the object will slide down the slide naturally. The tip of the article hits the stopper and its sliding is stopped, and due to its weight balance, the article rotates about the bending point as a fulcrum, and comes to lie above and parallel to the shooter. Once this condition is reached, the article will surely slide down the top of the shooter 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 computer and becoming locked as in the past. 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 no rotational force will be applied to the article. This will help overcome the frictional force with the equipment or shooter. 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 shooter 2, and then naturally slides down on the shooter 2, which is the same as in the conventional structure. Furthermore, stand 1
In order to more reliably feed the article A pushed in the direction of the arrow, a pair of rollers 3 are installed above, one of which is driven to rotate by a motor or the like. After A is sandwiched between the rollers 3, it is 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 provided at the upper end of the shooter 2 so as to be bent in a dogleg shape with respect to the shooter 2.
is installed. A stopper 6 is attached to the tip of the bending table 5.

When the tip of the article A that has been fed on the table 1 gradually moves away from the table 1, the tip becomes heavy and loses its balance, and due to the weight, it naturally falls from the tip. . The position of the slide 5 is set so that the tip of the tip rests on the slide 5 during the process of falling, so in this state, the article A passes over the slide 5 until its tip stops. Slide down naturally until you hit 6. This sliding allows the rear end of the article A to be sufficiently separated from equipment such as the table 1 or its wall 1A, 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 the object slides down the slide 5 and stops when its tip hits the stopper 6, the weight of the object is balanced around the bending point B, which is the boundary between the shooter 2 and the slide 5, as shown in FIG. It rotates clockwise and comes to lie above and parallel to the shooter 2 as shown in FIG.

During this rotation process, the rear end of the article A never collides with the wall surface 1A. Even if a collision were to occur, there is a rotational force acting on the article A at this time, and this rotational force will overcome the frictional force between the rear end of the article A and the wall surface 1A, so that this rotation will be prevented. 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 shooter 2 then naturally slides down on the shooter 2. Since the shooter 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.

(Effects of the Invention) As described in detail above, according to the present invention, articles being fed can be locked by a simple configuration in which a sliding platform and a stopper are simply installed in the shooter. With this, it is possible to reliably avoid the situation where the feed is stopped due to the length of the object, and the feeding direction can be reversed by allowing the object to slide down and naturally rotate depending on the length of the object. For this purpose, it does not require a balancer or other mechanical movement mechanism, so it can have a simple configuration, and furthermore, it has the advantage that it is extremely easy to adjust different items. .

Claims (1)

[Claims] 1. A long article that is pushed out along the longitudinal direction from the surface of equipment such as a machine is fed in a direction opposite to the feeding direction.

The article feeding device is provided with a stopper at the lower end of the sliding table for sliding the article down by at least half the length of the article and stopping the article.
