Fast stamping-press end material collector

Abstract

A fast stamping-press end material collector comprises a tray, one or more diverging chutes, and a moving mechanism, arranged such that the work pieces processed by stamping machine slide to the tray through the diverging chutes, and the moving mechanism moves the tray forward or backward when each work piece slides to the tray for the work pieces collected uniformly in the tray.

Description

FIELD OF THE INVENTION

The present invention is related generally to a stamping machine, and more particularly, to a fast stamping-press end material collector to replace human work and to achieve automatic collection of work pieces.

BACKGROUND OF THE INVENTION

In state-of-art metal machining process, the throughput of a fast stamping machine achieves as fast as 150 pieces per minute, and therefore the work pieces after stamped are collected before clean-up process by either picking the work pieces up and put them in basket by hand or allowing them to directly fall into basket standstill at the end material exit. However, the former work needs more manpower and thus increases the cost, while the latter method, even does not waste that much manpower, stacks the work pieces as a pile and causes the work pieces to collide and drag to each other and cause damages.

Therefore, it is desired a fast stamping-press end material collector to replace human work and to achieve automatic collection of work pieces.

SUMMARY OF THE INVENTION

One object of the present invention is to provide a fast stamping-press end material collector to replace human work.

Another object of the present invention is to enhance the automation for a stamping machine.

In a fast stamping-press end material collector, according to the present invention, the work pieces after processed by stamping machine slides to a tray through a diverging chute, and a moving mechanism moves the tray after each work piece sliding into the tray such that the next work piece will not stack over the previous work piece. As a result, the work pieces will be collected uniformly in the tray.

BRIEF DESCRIPTION OF DRAWINGS

These and other objects, features and advantages of the present invention will become apparent to those skilled in the art upon consideration of the following description of the preferred embodiments of the present invention taken in conjunction with the accompanying drawings, in which:

FIG. 1 shows a top view of a fast stamping-press end material collector according to the present invention; and

FIG. 2 shows a side view of the fast stamping-press end material collector of FIG. 1.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a top view of a fast stamping-press end material collector 100 according to the present invention, and FIG. 2 shows a side view of the fast stamping-press end material collector 100. In the collector 100, the work pieces after processed by stamping machine are transferred by conveyer belt 102 to entrance 1042 of diverging chute 104, above which gates 106 are arranged to diverge the work pieces entered from the entrance 1042 to eight exits 1044 of the diverging chute 104. Each exit 1044 has a feeding hole 108, and when a work piece is thereabove, the feeding hole 108 is open to allow the work piece to fall in the collection area 1102 of the tray 110. In this embodiment, the tray 110 is placed on platform 1122 of moving mechanism 112 and fixed by positioning mechanism 1124. The feeding hole 108 is closed right after each work piece falls into the tray 110 to prevent the work piece afterwards from falling into the tray 110 to cause stacking over the previous one already on the tray 110. Then the moving mechanism 112 moves, for example forward or backward, to move the tray 110 such that the portion of the collection area 1102 without work piece thereon aligned to the feeding hole 108 for receiving the next work piece. When the tray 110 is full of work pieces, the moving mechanism 112 moves the tray 110 to automatic stacking mechanism 114 to stack the tray 110. After stacking several trays 110 that are full of work pieces therein, the stacked trays 110 are sent to conveyer belt 116 for further cleaning step. When a tray 110 on the platform 1122 is moved out, the moving mechanism 112 moves the platform 1122 to position below automatic tray provider 118 where an empty tray 110 is automatically sent to the platform 1122. While interchanging the trays 110, the work pieces are continuously transferred to the diverging chute 104 by the conveyer belt 102, but only reach the feeding hole 108. The feeding hole 108 does not open to allow the work pieces to fall therethrough until the empty tray 110 is positioned well thereuner.

While the present invention has been described in conjunction with preferred embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and scope thereof as set forth in the appended claims.
