Abstract

Abstract A coin accumulator assembly for use in a coin wrapping machine is provided. The coin accumulator assembly comprises a coin accumulator tube, a shutter movably inserted into the coin accumulator tube for supporting coins stacked in the tube until a predetermined number of coins is accumulated and for opening to pass coins for a further treatment when the predetermined number of coins is accumulated in the tube, and a system for stepwisely lowering the shutter during the coin counting and accumulating operation. The system for effecting stepwise lowering of the shutter includes a support member for supporting the shutter and having a threaded hole, a screw shaft thrusting through said threaded hole of the support member, a reversible motor for rotating the screw shaft, and a guide rod to be slidably engaged with the support member for preventing the support member from being rotated but for guiding the same in the downward or upward direction when the screw shaft is rotated. A modified system including a rack-and-pinion unit may be used in place of the aforementioned system. A further modified system including a swingable arm for lowering or raising the support member is also disclosed herein. Further disclosed are the control systems for controlling the coin accumulator assembly in accordance with the pre-set control sequence.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 159 words
A coin accumulator assembly for use in a coin wrapping machine, comprising a coin accumulator tube, a shutter movably inserted into said coin accumulator tube for supporting coins stacked in the accumulator tube until a predetermined number of coins is accumulated and for opening to pass coins for a further treatment when said predetermined number of coins is accumulated in said coin accumulator tube, and means for stepwisely lowering said shutter, wherein said coin accumulator tube has a vertically-extending slit and a circumferential slit formed at the lower portion of the tube, and said shutter includes substantially symmetrical shutter plates each having a generally semicircular free end, an elongated stem portion and a generally trapezoidal base portion, said shutter plates being closed during the counting and accumulating operation with their free ends snugly received in the cavity of said coin accumulator tube to form the bottom of the tube and with their stem portion extending through said vertically-extending slit.
Claim 2
Dependent Claim 159 words
A coin accumulator assembly for use in a coin wrapping machine, comprising a coin accumulator tube, a shutter movably inserted into said coin accumulator tube for supporting coins stacked in the accumulator tube until a predetermined number of coins is accumulated and for opening to pass coins for a further treatment when said predetermined number of coins is accumulated in said coin accumulator tube, and means for stepwisely lowering said shutter, wherein said coin accumulator tube has a vertically-extending slit and a circumferential slit formed at the lower portion of the tube, and said shutter includes substantially symmetrical shutter plates each having a generally semicircular free end, an elongated stem portion and a generally trapezoidal base portion, said shutter plates being closed during the counting and accumulating operation with their free ends snugly received in the cavity of said coin accumulator tube to form the bottom of the tube and with their stem portion extending through said vertically-extending slit.
Claim 3
Dependent Claim 95 words
A coin accumulator assembly as claimed in claim 1, wherein said means for stepwisely lowering said shutter includes a support member for supporting said base portions of said shutter plates and having a threaded hole, a screw shaft thrusted through said threaded hole of said support member, a driving system including a reversible motor for rotating said screw shaft, and a guide rod to be slidably engaged with said support member for preventing the support member from being rotated but for guiding the support member in the downward direction when said screw shaft is rotated.
Claim 4
Dependent Claim 70 words
A coin accumulator assembly as claimed in claim 1, wherein said means for stepwisely lowering said shutter includes a support member for supporting said base portions of said shutter plates, a pinion mounted to said support member, a motor mounted on said support member for driving said pinion, and a rack meshing with said pinion and extending in the vertical direction to guide said support member in the downward direction.
Claim 5
Dependent Claim 56 words
A coin accumulator assembly as claimed in claim 1, wherein said means for stepwisely lowering said shutter includes a support member for supporting said base portions of said shutter plates, a swingable arm having one end engaged with said support member, a cam plate engaging with said swingable arm, and means for rotating said cam plate.
