Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a micro joint (a micro joint that does not separate products during cutting and transportation) when a large number of sheet metal products are manufactured from metal plate materials by a punching machine, a laser cutting machine, or the like. (Cut part) to complete the cutting process, and in the process of separating the cut processed plate into product and waste in the next step, carry out the work of loading the cut processed plate, separating the product, carrying out, and carrying out the waste material continuously. The present invention relates to a micro joint separating device that is automatically automated.

[0002]

2. Description of the Related Art Cutting-processed plate materials accumulated on a material storage shelf or pallet of a cutting machine are manually carried into a separator or a workbench and vibrated by vibrating by hitting with a machine or a hammer to produce products and waste materials. Products are separated and waste materials are carried out by hand or on a belt conveyor.

[0003]

In the conventional micro joint separating step, the cut jointed plate materials accumulated on the material storage shelves or pallets of the laser processing machine and punching processing machine are manually operated by the micro joint separating device or the separating work table. Have been delivered to.

The cut plate materials accumulated on the pallet are
When cut, they become uneven, and they are caught in the lateral direction, making it difficult to separate them.

Further, the carrying-in work requires two people's work and manpower, and when supporting and carrying both ends of the cut processed plate material whose strength is weakened by cutting, the center hangs down, the micro joint part is destroyed by the deformation and the product Hanging or separating,
There were problems such as damage, deformation, and loss.

If the number of micro joints is increased or increased so as not to be damaged during cutting and transportation, it will be difficult to separate even if hit hard with a hammer, resulting in heavy labor and deformation of the product. There were problems such as.

Further, the waste material after separation is easily deformed and difficult to carry by a two-person operation, and moreover, there are many dangerous points such as sharp edges, burrs and burrs, which makes it difficult to handle.

According to the present invention, a micro joint which is inexpensive, has a simple mechanism, can carry out the work of carrying the cut plate, separating the product, carrying out the product, and carrying out the waste material continuously without relying on human labor. The purpose is to provide a separating device.

[0009]

In order to achieve the above object, the microjoint separating device of the present invention comprises a material supplying device and a product separating device.

Further, the material supply device accumulates the cut-processed plate materials, which have been cut by the punching machine and the laser cutting machine, on the upper material accumulating shelf, and accumulates the remaining waste materials after separating the products. This is a device that saves space by providing a waste material stacking shelf in the lower stage, and further separates the uppermost one of the cut and processed plate materials stacked on the material stacking shelf by a lifter with an adsorber.

Further, the product separator has a function of driving up and down and further inclining in two steps, and is covered with a flat cover having artificial grass (a synthetic resin brush-like object) stuck on the upper surface thereof.
A table with a pallet equipped with a scraper that moves on the cover in the direction of the material supply device and slides on the cover, and a plurality of vibrating devices for separating the micro joints of the cut plate material from fatigue in a short time and separating them. The product storage bucket is configured to store the product.

Next, the means for continuously automating the operations of carrying in the cut plate material, separating the product, carrying out the product, and carrying out the waste material of the micro joint separating device will be described.

The cut processed plate materials cut by a punching machine, a laser cutting machine, etc. are accumulated on a material accumulating shelf of a material supply device, but the cut processed plate materials are cut so that the cut portions become uneven, and It interferes and is difficult to slide laterally.

Therefore, the lifter with an adsorber is lowered to the upper end of the cut processed plate on the product separator side, and the adsorber adsorbs only the uppermost sheet, and the movable type is provided on the table of the product separator. By raising the lifter with the suction device to a height at which the pallet can be inserted, it is possible to surely turn and separate the uppermost one of the cut processed plate materials.

In the cut plate material, the cut portions of the products connected by the micro joints are uneven. In order to easily insert the pallet without being caught in the unevenness, it is preferable to provide a rake portion bent to an appropriate length on the lower side of the insertion side of the pallet. By providing the scooping portion, it is possible to insert the pallet under the scooped plate material which has been cut and separated by the lifter with the suction device, while scooping it up (shown in FIG. 7).

When the insertion is completed, the suction device releases the cut plate material. The cut plate material is stored on a pallet and transported to the bottom of the vibration device.It is then moved up to the retractable clamp position provided on the vibration device, inserted into the retractable clamp of the vibration device, and retracted. Hold with a clamp.

Therefore, since the cut and processed plate material is conveyed in a state of being stored on a flat pallet, there is no deformation such as dripping at the center, and the product is not separated and is not deformed or damaged. It can be carried in and held by a retractable clamp.

When the cut processed plate material is held, the table is lowered and the pallet is retracted onto the product stacking shelf, so that the cut processed plate material held in the retractable clamp of the vibration device has a central portion. It becomes a bridge state floating in the air,
Vertical vibration can be applied from both ends. Therefore, high-speed micro-vibration can be efficiently applied from a plurality of positions on both ends of the cut plate material, and the micro joint can be fatigue-broken in a short time.

The product separated from the cut plate material falls on the cover covering the table, the pallet moves onto the table, and at the same time, the product dropped on the cover by the scraper provided in the pallet. Extrude,
It is possible to carry it out on the product storage bucket, but for the reasons described below, artificial grass (a synthetic fiber brush-like object) is placed on the cover.
It is advisable to make the sliding surface of the scraper lower than the top surface of the artificial turf by sticking.

The reason for attaching the artificial grass is that the products separated by the micro joint separation device have various thicknesses, sizes, and shapes. Therefore, if there are holes or gaps on the top surface of the cover, the product may fall under the cover. Also, when extruding an ultra-thin product, there is a problem that it gets under the scraper. In order to solve this problem, it is effective to attach the artificial grass and make the sliding surface of the scraper lower than the upper surface of the artificial grass (shown in FIG. 6).

When the waste material is carried out, the strength of the waste material separated from the product is weak, the product is deformed when supported by both ends, and sharp edges are generated, which makes it difficult to handle.

Therefore, when the pallet completes carrying out the product, the table is raised and the waste material held in the retractable clamp is released from the clamp, thereby storing the waste material on the flat pallet and lowering the table,
Even if the pallet is moved to the lower side of the material accumulation shelf, it does not interfere,
Moreover, it is inclined at an angle so that the waste material does not fall naturally. Then, the pallet is moved onto the waste material accumulation shelf, and the waste material is naturally slid down by inclining the table at an angle at which the waste material slides down (shown in FIG. 8).

When the waste material slides down naturally, the pallet is returned to the table and the table is returned horizontally so that the waste material can be easily accumulated on the waste material accumulating shelf.
