Description

[Detailed Description of the Invention] The present invention relates to an apparatus for taking out stacked articles, particularly articles with irregularities or soft articles, one by one or one by one.

Generally, when taking out stacked flat plate-shaped items one by one, it is possible to do this by forcibly pushing the side of the item located at the bottom or top tier, which is an extremely simple method. If the item is soft, or if the item is soft, this method cannot be used because there is a risk of damaging the item, and the user has often resorted to inefficient means such as manually removing the item.

Therefore, if automation was to be achieved, the following equipment had to be used in the past.

In other words, from the lower outlet of the container in which the articles are stacked,
In order to move the articles down one by one to a conveyor or other transport means, the article receiving mechanism and the shutter for opening and closing the outlet have to be driven separately in order to reliably operate them.

For this reason, this type of device has the drawbacks of a large work index and an unavoidable increase in size.

Therefore, the present invention has been developed to improve and eliminate the above-mentioned drawbacks when taking out conventional articles.

The configuration of the present invention will be explained below according to the embodiments shown in the drawings.

In FIGS. 1 and 2, 1 is a driving roller conveyor;
2 is a magazine located above the driving roller conveyor 1 and has an opening 3 at the bottom; 4 is a magazine to be stored in a stacked manner within the magazine 2;

The article 4 is, for example, a soft carbon tray with unevenness.

Reference numeral 5 denotes a bottom side opening of the magazine 2, and 6 denotes a shutter which is disposed on both sides of the drive roller conveyor 1 and is horizontally slidable so as to face the bottom side opening 5 and enter or retreat into the magazine 2 while rotating. be.

The slide mechanism of the shutter 6 includes an L-shaped arm 8 that is pushed up by the protruding movement of the piston rod 7a of the cylinder 7 and is rotatable around the center, and this L-shaped arm 8.
and a slide member 11 that is attached to the tip of the guide member 9 and fits into the TR10 of the guide member 9 to convert the rotation of the L-shaped arm 8 into horizontal linear movement, and the shutter 6 is attached on the slide member 11. It is being

12 is a cam follower attached to both end faces of the shutter 6 via an arm 13 so as to be rotatable about a pivot 14; 15 is a stopper for restricting the rotation of the cam follower 12; and 16 is a cam follower attached to the pivot 14 to rotate the arm 13 as shown in FIG. This is a torsion spring that is biased in the clockwise direction (arm located on the left side) and counterclockwise direction (arm located on the right side) and brings it into contact with the stopper 15 in a normal state.

, 17 is a support plate for the articles 4 located below the drive roller conveyor 1 and directly below the magazine 2;
The drive roller 1a of the base plate 19 attached to the tip of the piston rod 8 is erected upright in the axial direction of the drive roller 1a.

A cam plate 20 is attached to both end surfaces of the support plate 17 and has a cam curved surface 20a at its tip.

This cam plate 20 is located directly below the cam follower 12 at the forward end position of the shutter 6, and is located directly below the piston rod 18a.
Along with the protruding movement of the drive roller 1 along with the support plate 17,
a, the cam follower 12 is pushed up, and rotated about the pivot shaft 14 over a predetermined angular range.

The article 4 has stepped portions 4a on both sides of the lower surface shown in FIG. 1, and in a stacked state, the shutter 6 can enter the convex portion 4b on the upper surface, the stepped portion 4a of the article 4 stacked on top of this, and the shutter 6. A space 21 is formed.

22 is a spring that constantly pulls the cylinder 7 side of the L-shaped arm 8 downward.

Next, the operation of the device of the present invention configured as above will be explained.

Now piston rods 7a and 1 of cylinders 7 and 18
8a are both retracted, the support plate 17 and the cam plate 20 wait below the drive roller conveyor 1, and the left and right shutters 6 enter into the magazine 2 and support the lower end of the article 4.

To take out the articles 4 one by one from this state, first, the piston rod 18a of the cylinder 18 is moved to protrude, and the support plate 17 and the cam plate 20 are raised from the gap between the drive rollers 1a.

The cam plate 20 is attached to protrude a predetermined amount higher than the support plate 17, and near the final end of the above-mentioned upward movement, the cam follower 12 attached to the side surface of the shutter 6 is brought into contact with the cam curved surface 20a and is pivoted while being pushed up. 1
The arm 13, ie, the shutter 6, is rotated about 4.

When the support plate 17 slightly lifts up the article 4 held by the shutter 6, a limit switch (not shown) is activated to detect the rotation angle of the cam follower 12, that is, the shutter 6. Then, the cylinder 1
The protruding operation of the piston rod 18a of the cylinder 7 is stopped, and the piston rod 7a of the cylinder 7 is caused to protrude.

The protruding action of the piston rod 7a rotates the L-shaped arm 8 about the pivot shaft 8a in a clockwise direction (the arm located on the right side in FIG. 1) and in a counterclockwise direction (the arm located on the left side in FIG. 1). Then, the left and right slide members 9 are moved linearly in the horizontal direction to retreat.

As a result, the left and right shutters 6 move backward while returning to the horizontal position, and the cam follower 12 is removed from the cam plate 20.

The arm 13 is compressed by the stopper 15 by the biasing force of the torsion spring 16 and returns to its original state.

When the cylinder 7 causes the piston rod 7a to protrude to the protruding end, air or oil pressure is switched to quickly retract the piston rod 7a.

Therefore, the cylinder 7 side of the L-shaped arm 3 is connected to the spring 2.
A tensile force of 2 is provided, and the cylinder 6 is advanced by the tensile force of the spring 22 until the cam follower 12 comes into contact with the cam plate 20 which remains stopped at the rising end.

The shutter 6 then stops at this position.

The stop position of the shutter 6 can be detected by a limit switch (not shown) placed in the middle of the L-shaped arm 8, and then the cylinder 18 is switched and the piston rod is moved by the signal from the limit switch at this time. 18a
Operate entering and exiting.

The retraction movement of the piston rod 18a begins to lower the entire number of articles 4 supported on the support plate 17.

Along with this descent, the contact state between the cam plate 20 and the cam follower 12 is gradually released, and when the amount of descent of the support plate 20 reaches the height of one article 4, the cam follower 12
is detached from the cam plate 20.

Therefore, the shutter 6 receives the tensile force of the spring 22 via the slide member 11 and the L-shaped arm 8, enters the magazine 2 through the bottom side opening 5 of the magazine 2, and stops.

At this time, the above-mentioned space 21 formed between the article 4 located at the lowest stage and the next article 4 is located in the approach path of this shutter 6, and the shutter 6 does not damage the article 4.

Then, as the support plate 17 and the cam plate 20 continue to descend further, only the lowest article 4 is supported by the support plate 17 and descends, and the subsequent articles 4 are supported by the shutter 6.

In short, one article 4 is taken out.

The pulled-out articles 4 are sequentially placed on the drive roller conveyor 1 by lowering the support plate 17, and are thereby conveyed to a predetermined location.

The cylinder 18 returns to its original state.

After that, it is sufficient to repeat the above operation to take out the articles 4 one by one.

Although the above description has been made based on the case where the present device is used in a single row, the present invention is not limited to this and may be used in multiple rows.

As explained above, the present invention includes a magazine which is located above the drive roller conveyor and has an open bottom for storing stacked articles, and a magazine which is located on the left and right sides of the opening, with one end being pivotally supported and the other end being a shutter that is attached to an arm with a cam follower and a free open end and can be slid horizontally; an article support plate that is located below the drive roller conveyor and is movable up and down in the gap between the drive rollers; The cam plate is attached to both ends of the support plate, and comes into contact with the cam follower as the support plate moves up and down, raising and rotating the shutter. Not only can you automatically take out one sheet or one piece without damaging it, but it also makes it possible to shorten the work index and make the device smaller.
Suitable for mass production, improving workability and reducing costs.
