ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to the field of feeding systems.
DESCRIPTION OF THE RELATED ART
A compound molding machine receives tablets of a molding compound, melts the tablets to form a “melt” and injects the melt into a mold. General principles of operation of a molding machine are described in U.S. Pat. No. 5,470,218, which is incorporated by reference herein in its entirety.
For some types of pelletized materials, a molding machine may be fed by a compound magazine.
FIG. 6
shows a cut-away view of a conventional compound magazine
150
. The magazine
150
has a plurality of elongated tubes
152
for receiving compound tablets. The magazine
150
has a plurality of openings
151
on its top surface, through which the tablets are inserted into the tubes. Once the magazine
150
is full, it is coupled to the molding machine, to feed the tablets.
The tablets are loaded into the tubes manually. A hopper containing the tablets is placed on top of the magazine
150
. The operator has to shake the magazine and hopper till the tablets fall through the openings
151
into the tubes
152
. Manual loading of the compound magazine
150
is a very time consuming process. Experience has shown that this manual loading procedure may take approximately ten minutes per magazine. For a single molding machine, up to two hours per day of processing time may be lost due to delays in manually filling the compound magazine
150
.
In addition to being time consuming, manual loading of the compound magazine generates a large amount of dust, and the work itself causes worker fatigue. A system and method is desired for relieving the worker from the arduous task of manually loading the compound tablets into the magazine.
SUMMARY OF THE INVENTION
One aspect of the present invention is a feeding system including a hopper for containing material and a magazine, into which the material is fed by the hopper. The magazine is capable of feeding the material into a molding machine. The magazine is slidably seated on a reciprocating plate. The reciprocating motion of the plate causes the magazine to move with a reciprocating motion, thereby causing the material to fall from the hopper to the magazine.
Another aspect of the invention is a method for loading a magazine capable of feeding material into a molding machine. The material is loaded into a hopper above the magazine. A plate is moved with a reciprocating motion. The magazine is slidably seated on the plate, so that the reciprocating motion of the plate causes the magazine to move with a reciprocating motion, thereby causing the material to fall from the hopper to the magazine.
These and other aspects of the invention are described below with reference to the drawings and the exemplary embodiment.
