Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutting, aligning and stacking device for cutting, stacking, and aligning metal plate-like laminated material products such as lead frames and display tube meshes.

[Prior art and its problems]

Metal plate-shaped products such as lead frames and display tube meshes are made by etching a continuous metal material, cutting it to a predetermined size in a peeling finishing process, and then stacking and aligning the products by inserting interleaving paper.

When stacking and aligning the metal sheet products mentioned above, if they are stacked without inserting interleaving paper, the stacked products may deform, rust,
Because phenomena such as discoloration occur, interleaving sheets must be inserted.

Rust-proof paper is suitable as this interleaving paper, but since rust-proof paper has a high air permeability, if it is cut to a specified size and fed by vacuum suction, accidents such as double-sheet removal may occur, which is not desirable. For this reason, paper with low air permeability such as kraft paper is used as the interleaving paper, and after stacking and aligning, the work of stacking and inserting rust-proof paper as the interleaving paper is done manually, but automation of the stacking and alignment work is not possible. It wasn't done.

In addition, if the interleaf paper is cut into sheets and then inserted, there are problems such as air resistance, resulting in poor stacking accuracy, and the size of the interleaf paper must be larger than the product size, making it difficult to use the material. There was waste.

Furthermore, since anticorrosion paper is generally supplied in a roll, cutting it into sheets before use requires many steps and is inefficient.

[Problem to be solved] Even when continuous rust-proofing paper is used as the interleaf paper inserted when cutting metal sheet products made from continuous metal materials into predetermined sizes and stacking and arranging them,
It is an object of the present invention to provide a cutting, aligning and stacking device that allows for good stacking and automatically stacks and aligns.

[Means for solving problems]

A delivery roller that intermittently sends out a laminated material made by overlapping a continuous metal plate-like product and a continuous interleaving paper to a predetermined length, and cuts the laminated material fed by the delivery roller at a predetermined position. a cutting blade for cutting, a cutting pedestal, a plurality of freely rotating rollers that hold the tip of the fed laminated material, carry out the cut laminated material in the carrying out direction, and bring the end into contact with the projecting plate;
The alignment device is provided with a loading platform below the free-rotating roller, and the free-rotating roller is rotated by an endless rotating drive belt provided on the upper surface of one end thereof, and each free-rotating roller has both ends thereof This is a cutting, aligning and loading device that is attached to a chain via a bracket and can be moved away from a loading table by feeding the chain.

[Effect]

By providing a plurality of freely rotating rolls, the feed end side of the laminated material made by overlapping a continuous metal sheet product and interleaf paper is supported horizontally, and the cut laminated material is conveyed in the direction of the veneer. , the tip can be aligned in place.

At the same time, the freely rotating roller attached to the chain allows the laminated material to be retracted while it is in contact with the veneer or while being moved toward the veneer, so the cut laminate material can be placed on the loading table. They can be stacked neatly on top.

〔Example〕

An embodiment of the present invention will be described in detail.

As shown in FIG. 1, a delivery roller 1 that intermittently delivers a predetermined length of a laminated material in which a rolled-up rust-proofing paper a is superimposed on a rolled-up metal plate-like product b;
A cutting blade 2 and a cutting cradle 15 that cut the fed laminated material at a fixed position, hold the tip of the fed laminated material, convey the cut laminated material in the carrying out direction, and cut the edge of the laminated material. A plurality of freely rotating rollers 5 are brought into contact with the projecting plate 16, and a loading platform 3 is placed below the rollers 5.
The rollers 5 rotate with an endless rotary drive belt 12 pressed against the upper surface of one end thereof, and each roller 5 is attached to the chain 4 through a blanket 10 at both ends thereof, and This is a stack alignment device that can be moved away from the top of the loading table 3 by feeding the loading table 3.

Here, the amount of feed of the laminated material is determined by rotating and stopping the feed roller intermittently according to the amount of pulses using a pulse motor or the like.
This is done by controlling the number of rotations. The laminated material sent out for a predetermined length is cut into sheets by a cutting blade 2 that descends as shown by the dotted line in FIG. As shown in FIG. 2, the cut laminated material is conveyed in the forward transport direction while remaining laminated on the upper surface of each rotating roller 5, and its tip abuts against the projecting plate 16, and the tip of the laminated material The detection signal from the transmission photoelectric detector 18 detects the roller 5.
As shown in FIG. 3, the chain 4 is started running to the left in the drawing, is rotated in contact with the rotary belt 12, is moved to a retracted position on the left side from the upper side of the loading platform 3, and is moved to the upper surface of the roller 5. The cut laminated materials at are dropped onto the loading table 3 and stacked.

The proximity switch 19 detects the stacked laminated materials, and as soon as the laminated materials come into contact with each other, the roller 5 is returned to its original position above the loading table 3 by the chain 4 which rotates rightward in the drawing. The return position setting is controlled by the air cylinder stroke or limit switch. Then, the rollers 5 start rotating again in order as the endless rotation drive belt 12 is pressed from above. By pressing and rotating the upper and lower unwinding rollers 1, the rust-proof paper a and the laminated plate-like product are sent out in a stacked state for a predetermined length from the cutting table 15 onto the upper surface of the rotating roller 5, as described above, Repeat the feeding, cutting, and stacking operations.

Moreover, FIG. 4 is a front view of the device of the present invention,
Sprockets 6, 7, 8, and 14 for drive rotation of the chain 4 are respectively supported by the frames 20 on both sides, and each free-rotating roller 5 presses a belt 12 provided with a drive source 11 from above onto the upper surface of one end thereof. This explains the state in which it is rotated.

In the above description, a proximity switch is used as a means for detecting the laminated material, but a photoelectric detector may also be used for detection in the same way.

〔effect〕

The device of the present invention has a plurality of free rotations arranged in parallel on the same horizontal plane that can move the plate-shaped laminated material in a laminated state in which continuous metal plate-shaped products and anti-corrosion paper are layered flatly. The rotating roller can be supported horizontally on a roller, and is effective as a horizontal support means necessary for cutting the plate-shaped laminated material. It is also effective as a sending means for sending out and aligning them by a projecting plate,
It is extremely effective as a compact device for cutting, laminating, and aligning, and it eliminates the need to replace paper with low air permeability with interleaf paper and then manually replace it with anti-rust paper, making the process easier. shortening,
Can be simplified.
