Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] Such as figure 1 Shown is a structural block diagram of an embodiment of the stacking counting sensing device. The counting pulse generation unit 100 outputs an initial pulse P1, and the narrow pulse filtering unit 300 performs narrow pulse filtering on the initial pulse P1 to obtain a counting pulse P2 after filtering out interference pulses. The stacking transmission speed conversion unit 400 converts the stacking transmission speed n into a control voltage UK, and the control voltage UK is sent to the narrow pulse filtering unit 300 to control the narrow pulse width filtered by the narrow pulse filtering unit 300 .

[0025] The counting pulse generation unit is a commonly used photoelectric switch, Hall switch, magnetic reed switch, or an inductive proximity switch, a capacitive proximity switch, and the like. When stacked products pass by on the transport line,...

Abstract

A stacking count sensing device comprises a count pulse generation unit, a narrow pulse filtration unit, and a stacking transmission speed transformation unit. The count pulse generation unit generates an initial count pulse for stacking count. The narrow pulse filtration unit includes a forward anti-interference circuit, a reverse anti-interference circuit and a data selector, and the output of either the forward anti-interference circuit or the reverse anti-interference circuit is selected as a count pulse by the data selector under control of the output count pulse. The device can automatically filter continuous positive narrow pulse and continuous negative narrow pulse interference. The maximum widths of positive narrow pulse and negative narrow pulse needing filtering can change with the change of the stacking transmission speed, and can be adjusted by changing the forward charging time constant and the reverse charging time constant respectively. The device can be applied to occasions in need of stacking count in all kinds of automatic stacking devices.

Description

technical field [0001] The invention relates to an automatic detection device, in particular to a stacking counting sensing device. Background technique [0002] In the automatic stacking process of printed matter, bottled beverages, canned beverages, empty bottles and cans, etc., it is necessary to count the number of stacked products. Counting the number of stacked products often uses photoelectric switches, Hall switches, reed switches, or inductive proximity switches, capacitive proximity switches and other detection devices to detect the transportation and transmission process of stacked products. When the stacked products on the transportation line are over Once (pieces), the detection device generates an initial counting pulse signal, and the number of stacked products is counted and stacked by various counting devices or control systems. Due to the shaking of the stacked product transmission process, the vibration of the transmission mechanism, and the vibration of ...
