Package Counting Sensing Device

Abstract

The invention discloses a packaging counting sensing device which comprises a counting pulse generating unit, a narrow pulse filtering unit and a packaging conveying speed changing unit. Initial counting pulses for packaging counting can be generated by the counting pulse generating unit; the narrow pulse filtering unit comprises a forward charge and discharge circuit, a reverse charge and discharge circuit and a data selector, and one of the forward charge and discharge circuit and the reverse charge and discharge circuit can be selectively closed under the control of the data selector, so that counting pulses can be outputted by the forward charge and discharge circuit or the reverse charge and discharge circuit. The packaging counting sensing device has the advantages that interference of continuous positive narrow pulses and continuous negative narrow pulses can be automatically filtered; the maximum widths of the positive narrow pulses and the negative narrow pulses which are required to be filtered can be changed along with change of the packaging conveying speeds; driving current ranges and the magnitude of forward and reverse anti-interference capacitors can be changed, so that the maximum widths of the positive narrow pulses and the negative narrow pulses which are required to be filtered can be adjusted; the packaging counting sensing device can be applied to various automatic packaging devices in places with requirements on counting packaging quantities.

Description

technical field [0001] The invention relates to a detection device, in particular to a packaging counting sensing device. Background technique [0002] In the automatic packaging process of various products, it is necessary to count the number of packaged products. The quantity counting of packaged products often uses detection devices such as photoelectric switches, Hall switches, magnetic reed switches, or inductive proximity switches, capacitive proximity switches, etc. to detect the transportation and transmission process of packaged products. When there are packaged products passing by on the transportation line, The detection device generates an initial counting pulse signal, and the number of packaged products is counted and packaged by various counting devices or control systems. Due to the vibration of the packaged product during transmission, the vibration of the transmission mechanism, and the vibration of the contact of the mechanical switch itself, there is a v...
