Abstract

PURPOSE:To prevent damage in articles by such a construction that the lid at the side face of each pallet opens upward as the pallet is inclined so as to lessen the head of the article falling onto the shoot as much as possible. CONSTITUTION:An inclinable table 6 is inclined by a cylinder 9 in order to supply articles in the pallet 1 to the next process etc. Thus the pallet 1 on the inclinable table 6 is inclined, and the articles inside tend to go out through pushing aside the lid 2. As the inclinable table 6 is more inclined, at this time, the roller 5 rolls on the guide rail 10, provided with a slope as illustrated by the arrow C, upward to turn the lid 2 up with respect to the pallet 1. Accordingly, exhaust hole opens at the bottom surface of the pallet 1 with its opening increasing continuously in compliance with the inclination of the table 6, wherefrom the articles are placed out little by little in appropriate amounts.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an article feeding device for gradually feeding small articles such as forged parts to the next process.

Many of these types of articles have irregularities and complex shapes.For example, there are parts such as gears.

Regarding the case where the parts that have been processed by the forging machine S are sent to the next processing station, first a pallet 2 is prepared, and a large number of these parts are placed individually on the pallet 2 and transported to the site for the next process.

In this case, a pallet containing parts is transported by a forklift or the like, and the entire pallet is placed on a supply device at the site. Next, operate this device, tilt the pallet,
The items in the pallet are discharged and supplied to the next process via the transfer chute.

By the way, pallets that have been conventionally used in cases such as the above are generally box-shaped with an opening at the top, and articles are taken in and taken out from the opening at the top. Therefore, when the pallet E is tilted as shown above to discharge the articles inside, the current situation is to gradually tilt the pallet and discharge the articles from the upper opening. Therefore, the items discharged from the pallet are pallet 1I.
It will fall from the upper edge of lrTJ onto the chute with a large drop. Moreover, because the shapes of the articles are complex, they often become entangled with each other and fall together, which poses a problem in that not only the articles cannot be fed smoothly, but also there is a risk of damaging the articles 2.

Therefore, a method can be considered in which a lid is provided at the upper opening portion Vc and the items inside are gradually discharged by adjusting this lid. However, in this case, a new device must be provided to open the lid itself, which inevitably complicates the entire device.

The present invention has been made in view of the above circumstances, and provides an article feeding device with a relatively simple configuration that can gradually and smoothly feed articles automatically without damaging the articles. The purpose is to

Hereinafter, the content of this invention will be explained in detail with reference to FIGS. 1 to 3.

First, in FIG. 1, numeral 1 in the figure is a pallet for storing articles. This pallet 1 is in the shape of a square box with a lid 2, and its bottom surface is designed to hang securely.
While the opening for inputting the articles 2 is provided at the top as in the conventional case, the outlet for discharging the articles is provided on one side, and the outlet is usually covered by the lid 2. this! 2 has a pair of arms 3 having a triangular shape as a whole on its left and right sides, and is attached via these arms 3 to a pair of pins 4 provided symmetrically on the outer surface of the pallet 11111. ing. Then, l[2 is bi/
It is freely movable up and down like an arrow with 4 in the center. In this case, it is preferable to locate B/4 on the glue surface of pallet 1 at a position far from M2, that is, at a position opposite to lid 2. By doing this, rotation due to the weight of IF5 is prevented. The dynamic moment can be increased and the closed state can be firmly maintained at all times.

Furthermore, a pair of rollers 5 are rotatably housed on the outside 1IIW6 of the arm 3, respectively.

This roller 5 is an operation part for opening M2,
112 from the bottle 4 which is the Ic1lIIJJ fulcrum of the lid 2
It is located nearby.

As shown in FIG. 2, the pallet 1 having the above configuration is transported by a 7-oak lift or the like and placed on a tilting table 6. One end of the tilting table 6 is attached to a horizontal shaft 8 at the top of the seven frames 7, and the tilting table 6 is rotatable vertically as shown by arrow B about the shaft 8. The tilting table 6 is configured to be tilted upward from a horizontal position by a cylinder 9 provided below. As this cylinder 9, a hydraulic type or an electric type is suitable as it can be stopped at any position at tide. When placing the pallet 1 on the tilting table 6, place the end of the pallet 1 on the shaft 8 side, and place the feet of the pallet 1 in a predetermined position on the tilting table 6.

In this way, when the pallet I is placed on the tilting table 6, the rollers 5 of the left and right arms 3 are placed exactly on the guide rails 10 provided on the upper part of the frame 7. The guide rails 10 are arranged in parallel on both left and right sides of the tilting table 6 and are fixed to the upper part of the frame 7, and the inclination angle in the opposite direction to the direction in which the tilting table 6 is tilted is 0! It is attached with.

Note that 11 is a shoot. This is for receiving the articles discharged from the pallet 1 and guiding the articles 2 elsewhere (to the next process, etc.), and is provided adjacent to the tilting table 6. This shoe) 11 is equipped with a vibrator (
(not shown) is attached.

With the article supplying apparatus configured in this way, the tilting table 6 is tilted by the cylinder 9 when the articles on the pallet 1 are to be supplied to the next process or the like.

Then, the pallet 1 on the tilting table 6 tilts, and the articles inside push aside the lI2 and try to come out according to the tilt. At that time, as the tilting table 6 tilts, the roller 5 rolls on the guide rail lO with the slope 2 as shown by the arrow C.
As it goes up, the lid 2 rotates upward relative to the pallet 1. Therefore, at this time, as shown in FIGS. 3(a) to (d),
A discharge port opens from the bottom side of the pallet 1, and a discharge port of a size corresponding to the tilting table 6 opens in conjunction with the opening, and articles are gradually discharged from there in appropriate amounts. The articles are then smoothly supplied to the next process etc. via the chute 11. Note that depending on how the guide rail 10 is sloped, the opening degree of the discharge port can be changed depending on the slope GC of the tilting table 6. In that case, by making the near end of the guide rail 10 horizontal,
Upper limit of opening degree of Yaya 2? It can also be set.

By the way, as the pallet l is tilted, the force of the items inside trying to come out is applied as a force trying to open the lid 2, but in addition to its own weight, the same fulcrum is also applied to the inner body of the lid 2. 2
Because the position is far from the outlet, the rotational moment is large, so there is sufficient closing force, and the outlet is not pushed wide by the items inside, so it is always set to a constant value according to #i. It is possible to maintain the opening degree and gradually discharge an appropriate amount of articles P.

In addition, there is a risk that articles with complex shapes may get entangled with the discharge pressure release and become suspended in the discharge port, making it impossible to discharge them. , and by appropriately setting the inclination angle #12 of the guide rail 10, when the ridge 2 is opened and the article 2 is discharged (that is, when the article is supplied to the next process, etc.), the lid 2 is moved from the pallet 1911 to the chute 11 when the chute 11 is opened.
In other words, since the pallet 1 is opened with a downward slope from the inside to the outside, it is possible to effectively prevent the phenomenon of objects hanging in the air, and the objects can be discharged gradually and smoothly.

If a vibrator t* is attached to the chute 11, even articles discharged in a tangled state can be gradually (untangled) and fed to the next process etc. by applying vibration.

As explained above, according to the present invention, the pallet t
Since the lid of the tui tilts the pallet (therefore, it opens upwards), the outlet on the side gradually opens from the bottom side, making it possible to extremely reduce the height of the drop before the item falls onto the chute. This invention has the advantage of allowing goods to be fed gradually and smoothly without damaging the goods.In this invention, in particular, the tilting of the pallet and the opening/closing operation of the lid are linked. The device itself is relatively simple.
