Technical field

It the utility model is related to cigarette quality detection technique field, more particularly to a kind of new cigarette void-end detection device.

Background technology

Generally, cigarette lights the sagging depth of end pipe tobacco and lights the sagging depth of end pipe tobacco more than 1.0mm, or cigarette and exceed The cigarette that 3.0mm and empty sunken section are more than 1/2 is defined as nominal cigarette.Cigarette short is defined as in cigarette quality standard B class quality problems.Since cigarette short detection develops into photo-electric detection from condenser type detection, nominal recall rate, which has, necessarily to be carried Height, but because photo-electric detection stability is poor, accuracy rate is low, and cigarette short accuracy of detection requires higher, therefore still have Certain false drop rate, the situation that qualified cigarette is picked by mistake happen occasionally.

Utility model content

The purpose of this utility model is to provide a kind of new cigarette void-end detection device, can accurately detect nominal cigarette Branch, improve the accuracy rate and reliability of cigarette short detection.

To achieve the above object, the technical solution adopted in the utility model is：

A kind of new cigarette void-end detection device, including ultrasonic probe, sound velocity calibration device and signal control device, institute The sound velocity calibration device stated includes fixed length sleeve pipe, the first ultrasonic transceiver module and the second ultrasonic transceiver module, and described One ultrasonic transceiver module and the second ultrasonic transceiver module are oppositely arranged on the both ends of fixed length sleeve pipe, in the side wall of fixed length sleeve pipe Branch pipe is provided with, described branch pipe both ends connect with fixed length sleeve pipe and external environment, described ultrasonic probe, the first surpassed respectively Sound wave transceiver module and the second ultrasonic transceiver module electrically connect with signal control device respectively.

Also include nominal cigarette device for eliminating, described nominal cigarette device for eliminating includes synchronous detection module and cigarette is picked Except module, described synchronous detection module and cigarette are rejected module and electrically connected respectively with signal control device, described synchronous inspection Survey module to be used to gather cigarette pulse, described cigarette rejects module and is used to reject nominal cigarette.

Also include touch-screen, described touch-screen electrically connects with signal control device, and touch-screen is used to set cigarette manually Nominal a reference value.

Described ultrasonic probe is arranged on by installing plate in the side wall of cigarette spicing machine, the positive alignment of ultrasonic probe Cigarette pipe tobacco end.

Chute is offered on described installing plate, the bottom of described ultrasonic probe is provided with screw, ultrasonic probe Pass through being bolted on installing plate through chute.

Described signal control device is PLC.

Sound velocity calibration device of the present utility model passes through the first ultrasonic transmission/reception mould using the fixed length sleeve pipe being in communication with the outside The alternation of block and the second ultrasonic transceiver module, practical flight speed of the ultrasonic wave in current environment is obtained, is being utilized During the sagging depth at ultrasonic probe detection cigarette pipe tobacco end, signal control device replaces theoretical flight with this practical flight speed Speed calculates detection range, and the accuracy of detection of nominal cigarette has been effectively ensured, has improved the reliability of detection means.

Embodiment

As shown in figure 1, a kind of new cigarette void-end detection device described in the utility model, including touch-screen, ultrasonic wave Probe 1, sound velocity calibration device, cigarette device for eliminating and signal control device.Touch-screen is used for the base for setting cigarette short manually Quasi- value, is electrically connected by cable with signal control device.Ultrasonic probe 1 is used for the sagging depth for detecting cigarette pipe tobacco end, leads to Cross installing plate 2 to be fixed in the side wall of cigarette spicing machine, and be aligned with the cigarette pipe tobacco end on cigarette spicing machine.As shown in Fig. 2 Chute 3 is offered on installing plate 2, the bottom of ultrasonic probe 1 is provided with screw, and bolt passes through chute 3 and the bottom of ultrasonic probe 1 The screw at end coordinates, and is fixed on installing plate 2.When ultrasonic probe 1 is not aligned with cigarette pipe tobacco end, by loosening spiral shell Bolt can be such that ultrasonic probe 1 is moved along chute 3, and then realize position adjustment.

Signal control device of the present utility model uses PLC, and signal control device passes through the detection of contrast echo ripple probe 1 The sagging depth of cigarette and cigarette short a reference value, judge whether current cigarette is nominal cigarette.Nominal cigarette of the present utility model Device for eliminating includes synchronous detection module and cigarette and rejects module, synchronous detection module and cigarette reject module respectively with signal control Device electrical connection processed, synchronous detection module are used to gather cigarette pulse, and cigarette rejects module and is used to reject nominal cigarette.Spicing machine A cigarette is often produced, it is corresponding to export a pulse signal, when ultrasonic probe 1 detects that current caused cigarette is nominal cigarette Zhi Shi, synchronous detection module send its pulse signal to signal control device, due to cigarette part eject station and cigarette detection work The distance of position determines, therefore nominal cigarette reaches the time determination of cigarette part eject station, is rejected when the cigarette of corresponding pulses reaches During station, signal control device control cigarette rejects module and performs rejecting action, rejects nominal cigarette.

As shown in figure 3, sound velocity calibration device of the present utility model includes fixed length sleeve pipe 4, the and of the first ultrasonic transceiver module 5 Second ultrasonic transceiver module 6, the first ultrasonic transceiver module 5 and the second ultrasonic transceiver module 6 are oppositely arranged on fixed length set The both ends of pipe 4, branch pipe 7 is provided with the side wall of fixed length sleeve pipe 4, and the both ends of branch pipe 7 connect with fixed length sleeve pipe 4 and external environment respectively It is logical.When ultrasonic probe 1 detects to the sagging depth at cigarette pipe tobacco end, the first ultrasonic transceiver module 5 and the second surpass Sound wave receives and dispatches 6 pieces of timing alternations of mould, i.e., along the transmitting-receiving ultrasonic wave of fixed length sleeve pipe more than 4 times, and when ultrasonic wave is sent and received Quarter is transmitted to signal control device, signal control device by signal wire to fly according to the length and ultrasonic average of fixed length sleeve pipe 4 The row time calculates practical flight speed of the ultrasonic wave in current environment, is sent out according to practical flight speed and ultrasonic probe 1 The minimum air velocity at cigarette pipe tobacco end is calculated at the time of sending and receive ultrasonic wave, the accuracy of detection of nominal cigarette has been effectively ensured, has carried The high reliability of detection means.
