Abstract

The utility model relates to a detection device for the cigarette industry, specific detection device for detecting whether lack the strip in the smoke box that says so. The device comprises a smoke box (5) internally provided with smoke strips (6), and is characterized in that X-ray sources (1) and (2) are positioned on a smoke box strip-lacking detection frame body (10), X-ray detectors (3) and (4) are positioned at the hollow bottom of the smoke box strip-lacking detection frame body (10) and correspond to the X-ray sources (1) and (2), signal output ports of the X-ray detectors (3) and (4) are connected with a signal input port of a signal processor (8), a signal output port of the signal processor (8) is connected with a signal input port of a strip-lacking rejection unit (9), and output ports of a power supply unit (7) are respectively connected with a power supply input port of an X-ray tube (1) and a power supply input port of the signal processor (8) and a power supply input port of the strip-lacking rejection unit (9). The device has the advantages of convenience in maintenance, stable performance and accuracy in detection.

Description

Cigarette industry cigarette bar box-missing checkout gear

Technical field

The utility model relates to a kind of cigarette industry checkout gear, a kind of specifically checkout gear that whether lacks bar that is used for detecting in the smoke box.

Background technology

At present, in cigarette industry, be 50 cigarettes in order to guarantee every case cigarette, the method for cigarette industry employing in recent years has: the eddy induction type that utilizes vortex induction to detect principle lacks strip detector and utilizes the type of the weighing cigarette bar box-missing detector of weighing principle.Eddy induction type lacks strip detector owing to be to utilize to detect whether the aluminium paper in the bar cigarette exists to judge whether lack bar in the case in the smoke box, but detect the distance problem conflicting because of the EDDY CURRENT principle exists, make that the accuracy that detects is not high enough in the scarce bar of reality detects with detection resolution.The type of weighing cigarette bar box-missing detector is owing to being to utilize weighing principle, so at first very high to the weight discreteness requirement of every case cigarette; The vibration situation of second pair of erection unit also requires harshness; Adjusting maintenance in the 3rd actual the use waits all cumbersome.

Summary of the invention

The purpose of this utility model is to be to have avoided above-mentioned two kinds of technical weak points of scarce strip detector and a kind of cigarette industry cigarette bar box-missing checkout gear is provided.

The purpose of this utility model can reach by following measure:

A kind of cigarette industry cigarette bar box-missing checkout gear, the smoke box 5 of plume 6 is housed in comprising, it is characterized in that

x-ray source

1 and 2 is positioned at cigarette bar box-missing and detects on the framework 10,

X-ray detector

3 and 4 is positioned at the hollow base that cigarette bar box-missing detects framework 10, and with

x-ray source

1 and 2 corresponding positions,

X-ray detector

3 and 4 signal output connect the signal input part of signal processor 8, the signal output of signal processor 8 connects and lacks the signal input that bar is rejected unit 9, and the delivery outlet of power subsystem 7 connects power input and the power input of signal processor 8 and the power input that scarce bar is rejected unit 9 of

X-ray tube

1 and 2 respectively.

The beneficial effects of the utility model:

At first be the penetrability of utilizing X ray, overcome above-mentioned eddy current and lacked the not enough weakness of bar detection resolution.It two is that the ray energy that utilizes X ray to penetrate behind the object has the characteristic of decay, and the existence that can accurately tell plume is not.So just can accomplish scarce bar noncontacting measurement, avoid above-mentioned originally weighing to lack many deficiencies that bar brings fully smoke box.It has easy to maintenance, stable performance, detects advantage accurately.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, carry by the detection smoke box 5 that plume 6 is housed in smoke box conveying roller 11 generals, when when smoke box 5 lacks bar detection framework 10 from case in, passing through,

x-ray source

1 and 2 on the framework sends X ray, by corresponding with

X-ray detector

3 and 4 respectively behind the smoke box 5, allow

X-ray detector

3 and 4 receive, when smoke box 5 lacks bar as if generation, then move to

x-ray source

1 or 2 when lacking the bar position, when reaching

ray detector

3 or 4 correspondence positions,

X-ray detector

3 or 4 will receive stronger X ray signal, go out whether lack bag in the smoke box by the strong and weak decidable of the signal that detects

X-ray detector

3 or 4.

Structural principle schematic diagram of the present utility model as shown in Figure 2; among Fig. 2

X-ray tube

1 and 2 and

X-ray detector

3 and 4 between be to move tested smoke box 5; plume 6 is housed in the smoke box; attenuation characteristic when seeing through object according to X ray as can be known; when certain plume lacks in the case; then be eager to excel under the more preceding normal condition of the signal that

X-ray detector

3 or 4 receives under correspondence position; this signal will be delivered to signal processor 8 and handle, and signal be delivered to after the processing to lack bar rejecting unit 9 execution smoke box removing functions or shut down function again.

Claims

1, a kind of cigarette industry cigarette bar box-missing checkout gear, the smoke box (5) of plume (6) is housed in comprising, it is characterized in that x-ray source (1) and (2) are positioned at cigarette bar box-missing and detect on the framework (10), X-ray detector (3) and (4) are positioned at the hollow base that cigarette bar box-missing detects framework (10), and with x-ray source (1) and (2) corresponding position, the signal output of X-ray detector (3) and (4) connects the signal input part of signal processor (8), the signal output of signal processor (8) connects and lacks the signal input that bar is rejected unit (9), and the delivery outlet of power subsystem (7) connects power input and the power input of signal processor (8) and the power input that scarce bar is rejected unit (9) of X-ray tube (1) and (2) respectively.
