Description

Metal plate material feeder {Auto feeder for sheets}

The present invention relates to an automatic metal sheet material supply device, and more particularly, to an improvement plan of Utility Model Registration No. 236678, which is the applicant's prior registration.

In general, various types of feeders are drawn and used to process metal plate materials.

Among them, the design of No. 236678, which is a pre-registered application of the applicant, made it possible to automatically supply metal sheet-like materials automatically.

Briefly, the contents of such a pre-registration design;

A material supply unit which is mounted on the ground or the reference plane of the machine by placing a workpiece laminated with a predetermined number of materials required for processing;

It is provided directly above the material supply unit, and is largely composed of a material transfer unit formed of a frame equipped with a vacuum suction pipe, a finger assembly, a magnet rail and a sensor for supplying and transporting the material.

The material supply part is provided with a plurality of 'I'-shaped rail through the base in a direction orthogonal to the supply direction of the material, the drive roller is connected to both sides by a drive shaft through a drive means such as a sprocket above the rail Multiple dogs are placed.

Both ends of the drive shaft are provided with a supply bracket for fixing the supply plate is mounted with a plurality of supports that are mounted in direct contact with the material,

The support is equipped with a spring-loaded expansion and contraction material is provided at equal intervals across the front of the supply plate.

A frame equipped with a vacuum suction pipe, a finger assembly, a magnet rail, and a sensor is located directly above the material supply unit configured as described above, and one end of the frame is placed above the cutting table of the machine, and the other side is spaced a predetermined distance from the reference plane on which the material supply unit is installed. The material transfer part is formed through the two cradles.

The frame is arranged a plurality of equal intervals in the longitudinal direction by using a square pipe having a square cross section,

Above the frame provided at both edges of the plurality of frames, a vacuum suction pipe composed of an air cylinder and a suction plate to set up the working direction from the upper side to the lower side in order to mount and raise the material supplied through the material supply unit has a large number of longitudinally Dogs are provided.

Including the frame on which the vacuum suction pipe is formed, a bottom surface of the entire frame is provided with a magnet rail for placing the material mounted through the vacuum suction tube to be transferred to the processing machine.

The magnet rail forms a permanent magnet interposed on the bottom of the frame and rolling bearings on both sides thereof to match the supply direction of the material so that the material mounted by the magnetic force of the permanent magnet slides and moves by the rolling action of the bearing. .

As described above, the frame formed with the vacuum suction pipe and the magnet rail required for the attachment and the transport of the material forms a finger assembly for clamping the material mounted upwardly with the cradle and transferring the material to a machine with a predetermined standard.

The automatic sheet metal material supply device configured as described above is raised and lowered by the vacuum suction pipe, the plate material supplied through the material supply unit, and then fixed the plate material is mounted through the magnetic force of the magnet rail.

As described above, the automatic sheet metal material supply device for supplying the material through the magnet rail and finger assembly,

The main purpose is to minimize the loss of materials during processing by providing the mounting and supply of the material through the finger assembly.

However, in spite of the above advantages, the automatic feeding device is stacked on the material supplying part, and the material fixed to the magnet rail does not form the right angle at the cutting direction and the moving direction of the processing machine, and thus frequently the processing defect occurs.

This means that when the plate material is laminated to the material supply part, it is almost impossible to set the exact squareness with the processing surface.

Even when the material is mounted on the magnet rail and the finger assembly, there is no device that can correct the declination of the processing surface and the material.

In addition, the distance between the material supply unit and the frame where the vacuum suction pipe is located is easy to mount the material in the initial laminated state,

As the stacked materials are exhausted, the work of lowering and rising the vacuum suction pipe increases the work stability, and also causes problems such as productivity decrease due to the increase of working time.

Therefore, the present invention is designed to solve the above problems and to supply the material by moving up and down by a conveying means such as a ball screw, the material supply unit for placing the material is placed, and

In addition, to correct the entry angle perpendicularity of the material mounted through the vacuum suction pipe in a portion orthogonal to the material supply direction, which is the edge of both sides of the frame forming the material conveying part,

It further comprises a material declination correction device composed of a cylinder and a guide device to improve the processing performance and quality of the material.
