Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a thin plate that is equipped with a stocker that can store thin plates horizontally and in parallel at regular intervals, and a device that horizontally conveys the thin plates stored in the stocker one by one. This relates to a supply device.

Structure of a conventional example and its problems The specific structure of a conventional thin plate feeding device is shown in FIGS. 1a and 1b. Reference numeral 1 denotes a stocker that stores the thin plates 2 horizontally and parallelly at regular intervals, and this stocker has a conveyor 4, 5 and 6, it is movable in the right angle direction.

Furthermore, when the stocker 1 is on the conveyor 5, that is, at position A in FIG. The thin plate 2 is forcibly pushed out in the direction of arrow X1 by an actuator 7 and transferred onto a conveyor 3, so that the conveyor 3 conveys the thin plate 2 in the direction of arrow X.

However, in such a configuration, the thin plate 2 is transferred to the conveyor 3.
Guide 8 to guide in the direction of arrow X so as not to come off the top
There was a problem in that the thin plate 2 and the thin plate 2 came into contact as shown by B in FIG.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides a thin plate feeding device that reliably automatically feeds thin plates one by one in the horizontal direction.

Structure of the Invention The thin plate feeding device of the present invention includes a conveyor that conveys a thin plate in a horizontal direction, and a conveyor that allows the tip of the conveyor to pass through the conveyor and put the tip of the conveyor inside so that the thin plate can be placed directly on the conveyor and conveyed. A pair of side plates are provided with a notch, and grooves are provided in the side plates so that the thin plates can be stored and taken out horizontally and parallelly at regular intervals, and a foot portion is provided at the bottom to enable conveyance by a belt or chain type conveyor. The stocker is equipped with a stocker and is capable of automatically supplying thin plates.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 2a and 2b, 10 is a belt conveyor that conveys the thin plate 11 in the direction of arrow X2 (horizontal direction), and is composed of a pulley 12b on which a belt 12a is stretched, and a motor 13 that drives the belt 12a. 14, the thin plate 11 is the belt conveyor 10
This guide 14 guides the thin plate 11 to be conveyed in the direction of arrow X2 without coming off from above, and is configured to be higher than the height when the thin plate 11 is placed on the belt conveyor 10. Reference numeral 15 denotes a stocker, and as shown in FIG.
Both ends of the thin plate 11 shown in the figure are supported, and the thin plate 11 can be stored and taken out horizontally and parallelly at regular intervals. 16 is a conveyor, and stocker 1
5 is provided between the supply conveyor 17 and the stocker takeout conveyor 18, and is supported so as to be movable up and down in the direction of arrow Y in FIG. 2a by a known ball screw or the like. When the stocker 15 is at position C in FIG. 2b, where the stocker 15 is on the conveyor 16, the conveyor 16 is lowered by a constant pitch at intervals where the grooves 20a of the stocker 15 are provided.

Further, as described above, this stocker 15 can be moved in a direction perpendicular to the belt conveyor 10 by the conveyors 16, 17, and 18 that convey the stocker 15, and the belt conveyor 15 shown by D in FIG. A notch 21 is provided in the side plate 20 shown in FIG. 3 so that the tip of the stocker 10 can pass through the inside of the stocker 15.

This notch 21 allows the thin plate 11 to be placed on the belt conveyor 10 when the stocker 15 is lowered by a certain pitch.
If more than half of the board is not covered, the thin plate 11
To prevent this, the tip of the belt conveyor 10 must enter the end face G of the stocker 15 to a point more than 1/2 of the width H of the stocker 15.
must be at least 1/2 of the width H of the stocker 15. 22 conveys the entire stocker 15 to the conveyor 16,1
Legs 23 are provided on 7 and 18 so as to be transportable, and 23 are connecting parts that connect the side plates 20.

The operation of the thin plate supply device having the above structure will be explained below.

In FIG. 4, a stocker 15 storing thin plates 11 horizontally and parallelly at regular intervals is placed on a conveyor 17 that conveys the stocker 15 (FIG. 4I), and is moved in the direction of arrow X3 by conveyors 17 and 16. The stocker 15 stops when the tip of the belt conveyor 10 is inside the stocker 15 (FIG. 4J).

In this state, each time the conveyor 16 descends in the Y1 direction and the stocker 15 descends by a certain pitch in the Y1 direction, the thin plate 11 is directly placed on the belt conveyor 10, and the thin plate 11 is moved by the arrow X shown in FIG.
It is transported in two directions.

Next, when all the thin plates 11 stored in the stocker 15 have been conveyed (K in FIG. 4), the stocker 15 rises in the direction of arrow Y2 and returns to the state in J in FIG. Therefore, the stocker 15 is moved in the direction of arrow X4, and stops when it is completely on the conveyor 18 (FIG. 4L).

After the stocker 15 is in the state shown in FIG. 4L, the next stocker (having the same shape and dimensions as the stocker 15) that stores the thin plate 11 is moved from the state shown in FIG. 4I,
The operations shown above are then repeated.

As described above, according to this embodiment, the thin plate with the conveyance guide, etc., as shown in B, which is caused by forcibly pushing out the thin plate in the direction of the arrow X1 by the actuator 7 and transferring it onto the conveyor 3 in FIG. 2
The sticking phenomenon disappears. As shown in FIGS. 2, 3, and 4, a foot portion 22 is provided to enable the stocker 15 to be conveyed by the conveyors 16, 17, and 18, and a cut 21 is provided in the stocker 15.
is provided so that the tip of the belt conveyor 10 can pass through the stocker 15, and by placing the tip of the belt conveyor 10 inside the stocker 15, when the stocker 15 descends on the conveyor 16 by a constant pitch, the thin plate 11 directly rides on the belt conveyor 10 and is conveyed in the direction of arrow X2, making it possible to automatically feed the thin plate 11.

In this embodiment, the stocker 15 is the conveyor 1.
Although conveyors 6, 17, and 18 are moved in a direction perpendicular to the conveyor 10, one of the conveyors 17 or 18 may be moved in the same direction with respect to the belt conveyor 10.

Effects of the Invention As described above, the present invention provides a notch in the side plate of the stocker so that the tip of the belt conveyor that conveys the thin plate can pass through in a horizontal plane perpendicular to the movement of the stocker, and a belt inside the stocker. The tip of the conveyor is inserted, and each time the stocker descends by a certain pitch, the thin plate is placed directly on the belt conveyor and smoothly conveyed in the horizontal direction, making it possible to automatically feed the thin plate.

In addition, since the stocker can be transported by a conveyor, it is possible to automatically supply the stocker, and because the conveyance and removal of the thin plate is not a forced extrusion method, there is no forced friction between the guide, conveyor and the thin plate, which is caused by wear. There is no need to replace the guide or conveyor belt, and a highly reliable thin plate feeding device can be provided.
