Coin deposit and summation memory device

摘要

A coin deposit and summation device having a coin denomination identification mechanism and a coin denomination summation mechanism. The device determines different mechanical movement paths according to different diameters of different coin denominations, with each mechanical movement path resulting in a mechanical trigger corresponding to the identified coin denomination; each resulting mechanical trigger drives a mechanical counter wheel to perform denomination summation once according to the identified coin denomination. The device can be designed to achieve denomination identification and summation of 0.5, 0.25 and 0.2 dollar coins.

1. A coin deposit and summation device comprising a coin denomination identification mechanism and a coin denomination summation mechanism, wherein
the coin denomination identification mechanism comprises a frame; an end of the frame is provided with a coin slot; the coin slot has a moveable end; the moveable end is provided with a mover having a drive needle; the mover is movable along a composite slash track and cooperating with a sorting gate to perform sorting of coins of different denominations; the sorting gate has more than one channel; each channel is capable of receiving the drive needle; each channel corresponds to a respective coin denomination and each channel is provided with a drive rod capable of interacting with the drive needle; the coin denomination summation mechanism comprises a set of one-way rotary counter wheels; a one-way drive ratchet is provided on each of a counter wheel for ones position and a counter wheel for tens position or provided on each of the counter wheel for ones position, the counter wheel for tens position and a counter wheel for hundreds position; the drive ratchets are connected with a drive mechanism which is capable of receiving mechanical triggers from the drive rods and then correspondingly drives the drive ratchets and thus the counter wheels to achieve coin denomination summation;
the drive mechanism comprises a sector gear set, wherein each sector gear of the sector gear set has a trigger end capable of interacting with one or more than one corresponding drive rods, and has a tooth portion engaging with an outer gear of a corresponding drive ratchet on a side of a corresponding counter wheel for driving the corresponding counter wheel;a scale comprising a group of digits for indicating denomination summation is provided on each of the counter wheels; each of the counter wheels is provided on a right periphery with several count-linkage teeth and on a left side with a linkage tooth for carrying a digit; a linkage wheel is provided between adjacent counter wheels to move the adjacent counter wheels simultaneously for the purpose of carrying a digit;the counter wheel for ones position is driven by one corresponding drive rod;the counter wheel for tens position is driven by two corresponding drive rods; the counter wheel for tens position counts a whole digit or half a digit in each count; a digit is carried forward to the counter wheel for hundreds position for every ten digits counted in the tens position, or a digit is carried forward to the counter wheel for hundreds position in two times in which half a digit is first carried forward to the counter wheel for hundreds position when reaching a count of nine and a half digits in the tens position, and another half a digit is then carried forward to the counter wheel for hundreds position when there is a subsequent count of half a digit in the tens position;the sector gear set comprises a first drive wheel and a second compound wheel, both of which are biased on one side to an initial position of being capable of receiving mechanical triggers from corresponding drive rods; the first drive wheel is capable of interacting with a corresponding drive rod and is in linkage with the counter wheel for ones position; the second compound wheel is capable of Interacting with two corresponding drive rods and is in linkage with the counter wheel for tens position;the second compound wheel comprises an active wheel and a passive sector wheel, the active wheel is provided with a reset connection hole for connecting a connecting rod and an elastic member being a spring and is elastically fixed in the initial position, the passive sector wheel being in differential drive with the active wheel, a corresponding drive rod corresponding to the active wheel is capable of sending a mechanical trigger to the active wheel; the active wheel, when rotating differently compared with the passive sector wheel, delivers a mechanical trigger acting on a clutch frame of a linkage wheel between the counter wheel for ones position and the counter wheel for tens position to separate the linkage wheel; the active wheel, after differential rotation relative to the passive wheel, is in linkage with the passive sector wheel which then engages and Is in linkage with a corresponding drive ratchet on the counter wheel for tens position.
