Abstract
The utility model belongs to a passive character wheel type counting sensor which is composed of a driving wheel (1), a character wheel (2), a character wheel shaft (3), a small wheel (4), a small wheel shaft (5), a frame (6), a resistor (7), a metal spring (8), etc., wherein, the metal spring (8) and the resistor (7) connected with the metal spring are arranged on the bottom surface of the web plate of the character wheel (2), which is apart from a definite angle with the radius circumferences; the resistor (7) is bridged with a conduction band (10) on the surface of the character wheel shaft (3) through the metal spring (8) to form a measuring circuit. The rotation number of a counter can be directly measured by utilizing the matched use of an auxiliary device and a computer. The utility model has the advantages of simple structure, stable performance, easy fabrication, etc., and is suitable for passive counting measuring occasions.
Description
The utility model belongs to a kind of passive character wheel formula sensor for countering.
Existing character wheel formula counter is mechanical revolution counter, is made up of power wheel, character wheel, print wheel shaft, steamboat, little wheel shaft and framework, can directly read the accumulative total revolution, but can not realize long apart from revolution speed measuring.Recently also have and on the character wheel of character wheel formula counter, install contact switch, magnetosensitive switch etc. additional, make and rely on the active sensor for countering that adds the electric energy detection break-make, but must power in real time, just can carry out signal and transmit, count by other device again.When supply of electrical energy shortage or power pack break down, can't guarantee data transmission, can occurrence count device reading inconsistent with the sensing counting, and real-time power supply also must cause electric energy to expend.
The purpose of this utility model designs a kind of simple in structure, stable performance exactly, and counting relies on mechanical hook-up at ordinary times, and direct reading reads the passive sensor for countering of counting by servicing unit during measurement.
The utility model comprises power wheel, character wheel, print wheel shaft, steamboat, little wheel shaft and framework, sets up resistance, metal spring.Character wheel, resistance, metal spring and print wheel shaft have constituted the core of passive character wheel formula sensor for countering as critical component.The adradialia bottom surface is with the pin deck or the pickup groove of reservation two certain angles of being separated by in appropriate location on the radius circumference in each character wheel, so that metal spring is installed, its angle of being separated by can be 36 ° integral multiple.Metal spring can be selected tinsel or sheet metal for use.Resistance also is installed in character wheel with on the adradialia, the corresponding end of metal spring and resistance lead firm welding.The resistance of resistance can be according to measurement requirement, and preferred according to the principle of parallel circuit, guaranteeing has enough resolutions when measuring.Resistance can also save, with lead directly connect metal spring, its aided measurement device also will change thereupon.Treated some the conductive strips of making along the axis direction mutually insulated in print wheel shaft surface.Character wheel by power wheel drive, character wheel is each all with 36 ° corner stepping, when counter is in a certain revolution position, resistance forms metering circuit by metal spring and the cross-over connection of print wheel shaft conductive strips, utilize servicing unit and computer to be used, directly measure the revolution of counter, thereby realize the purpose of passive counting sensing.
Accompanying drawing 1 is a kind of front view of sensor for countering
Accompanying drawing 2 is a kind of character wheel side installation diagram of sensor for countering
Introduce a kind of embodiment of sensor for countering below in conjunction with accompanying drawing.This sensor for countering is made up of power wheel (1), character wheel (2), print wheel shaft (3), steamboat (4), little wheel shaft (5), framework (6), resistance (7), metal spring (8) etc.The pin deck (9) that metal spring (8) is installed is left with appropriate location on the radius circumference in the interior adradialia of character wheel (2) bottom surface, and the be separated by wire bonds of the corresponding end of 36 ° * 3, two metal springs and resistance (7) of two pin deck is firm.Treated 10 conductive strips (10) made along the axis direction mutually insulated in print wheel shaft (3) surface.One end of conductive strips (10) is connected with measurement mechanism.When the character wheel (2) of counter rotates in a certain position, resistance (7) is connected across on the conductive strips (10) of print wheel shaft (3) by metal spring (8), and form parallel circuit with other character wheel, by the platform of joining of aided measurement device and computer, directly measure the revolution of counter.
The utlity model has following characteristics: reasonable in design, simple in structure, stable performance, be easy to system Make, be adapted to especially passive count measurement occasion.
Claims (5)
1, a kind of passive character wheel formula sensor for countering, comprise power wheel (1), character wheel (2), print wheel shaft (3), steamboat (4), little wheel shaft (5) and framework (6), it is characterized in that, the resistance (7) that character wheel (2) disc bottom surface is equipped with metal spring (8) and links with it with the angle of being separated by on the radius circumference, there are the conductive strips (10) of some mutually insulateds on print wheel shaft (3) surface along axis direction.
2, sensor for countering as claimed in claim 1 is characterized in that, it can be on two pin deck (pickup groove) (9) of 36 ° of integral multiples with the angle number of being separated by on the week of radius garden that metal spring (8) is installed in the interior adradialia of character wheel (2) bottom surface.
