Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when manufacturing an aluminum profile, easily separates a profile determined to be defective from a fixed amount of profile cut into a predetermined size and carries it out. The present invention relates to a device for separating and carrying out profile members.

[0002]

2. Description of the Related Art Aluminum profiles are generally manufactured by hot extrusion, but the weight per unit length exceeds 20 kg due to the diversification of demand, and the weight of finished products cut into regular lengths is Items up to 200 kg can be processed. Incidentally, the aluminum shaped material continuously molded by the extrusion molding machine, after being cut to a fixed length, after removing the defective material through the inspection, by the loading device, it is stacked on a transport pallet every predetermined number, Be carried out.

The inspection of the aluminum profile is carried out on an inspection table installed at the end of the rear equipment of the extruder. The inspection table is a pedestal composed of a number of belt conveyors arranged in parallel, and the aluminum profile cut into a regular length is temporarily stored on the inspection table via the upstream conveyor and at least 2 Inspect the stored aluminum profiles by at least one inspector. At this time, the aluminum profile determined to be defective is lifted first and then simultaneously to the downstream side of the inspection table so that the inspector goes around both ends and does not damage the adjacent good aluminum profile. It is removed from the good material by moving.

[0004]

According to such a conventional situation, since the work of removing the defective material is performed entirely by manpower, the burden on the inspector is increased as the size of the aluminum material is increased. Not only is it too large and the work efficiency is poor,
There was a problem that unexpected accidents such as fatal accidents of workers and damages of good materials could not be avoided.

Therefore, an object of the present invention is to arrange a plurality of belt drive mechanisms and clamp mechanisms and to pull up only defective materials through a cargo handling belt, so as to efficiently and without damaging good materials. It is an object of the present invention to provide a separation and carry-out device for a profile, which can carry out a defective material by pulling it out from among good materials.

[0006]

The structure of the present invention for achieving the above object comprises a plurality of belt drive mechanisms for winding up a cargo handling belt, and a plurality of clamp mechanisms arranged corresponding to the belt drive mechanisms. The clamp mechanism clamps one end of the cargo handling belt hanging from the drive drum of the belt drive mechanism upward, and the belt drive mechanism and the clamp mechanism are mounted on a vertically movable lifting frame. ..

The clamp mechanism includes an eccentric member that rotatably supports the eccentric shaft and sandwiches the cargo handling belt between the eccentric shaft and a fixing member, and a drive source that drives the eccentric shaft and the eccentric member. You can

The lifting frame can also form part of the profile loading device.

[0009]

According to the structure of the present invention, the cargo handling belt hanging from the drive drum of each belt driving mechanism is folded up at the lower side of the defective material so as to be pulled upward from the opposite side and the pulled up one end is clamped. After being restrained by, the belt driving mechanism winds up and the elevating frame is raised, so that only the defective material can be pulled up. So, if you continue to move the lifting frame horizontally and lower it to release the clamp mechanism,
Defective materials can be carried out to any place.

The clamp mechanism including the eccentric member supported via the eccentric shaft clamps the cargo handling belt by sandwiching it between the fixed member and the eccentric member, but the eccentric member is clamped in the tightening direction depending on the weight of the shape member. Even if it over-rotates, the entire eccentric member can be displaced in the direction of separating from the fixed member by rotating the eccentric shaft first, and then the eccentric member is released in the releasing direction by an extremely slight force. It is possible to drive.

When the elevating frame forms part of the loading device, the entire loading device can be constructed using the loading device, and the function of the equipment can be easily improved.
