Whole integrated form list cigarette short detects device for eliminating
Technical field
The utility model relates to cigarette packing machine, especially the device that can detect and reject single cigarette short that uses on a kind of cigarette packing machine, specifically can the following cigarette warehouse compartment before cigarette enters diaphragm capsule put and be about to nominal cigarette and prop up rejecting, to cut the waste, the whole integrated form list cigarette short that improves packaging efficiency detects device for eliminating.
Background technology
At present, wrapping machine model such as GD type wrapping machine that domestic tobacco business is commonly used all adopt the mode that after cigarette props up diaphragm capsule nominal cigarette Zhi Jinhang is detected.Promptly according to the production of cigarettes packaging process, per 20 cigarettes prop up into a diaphragm capsule, are then 20 cigarettes in the whole diaphragm capsule to be propped up nominal cigarette and all eliminate manufacturing line if wherein there is a cigarette to prop up.This detection is rejected mode and can be caused whole packing unit production efficiency to descend, and 20 cigarette Zhi Shiji that at every turn eliminate individual pieces is wherein only arranged is the nonconformity cigarette, other all has been a cigarette, so just cause a large amount of wastes, even if a large amount of cigarettes that eliminate prop up by the use of lowering one's standard or status after the manual recovery, also increase work capacity, reduced the economic value that former cigarette props up.Just because of above drawback, this kind detects, the rejecting mode is badly in need of a kind of detection more reasonable, more high workload usefulness, the rejecting mode replaces.
Want to reach the detection mode that online in real time accurately detects and reject at nonconformity cigarette Zhi Jinhang, must solve that cigarette props up orientation problem in the high-speed production process, promptly prop up with the position of sensor, rejecting point and want relative fixed at detection, rejecting moment cigarette, also need solve the rational problem of some Position Design of rejecting in addition, promptly reject point and must be positioned at cigarette and prop up into the rational position before the diaphragm capsule.For this reason, the applicant has applied for that to State Intellectual Property Office a kind of name is called " single cigarette short detects and device for eliminating " in 2007, application number is the patent of invention of ZL200710020646.6, but in actual use, the applicant finds that this device exists following problem to need badly and overcomes.At first, because that former machine is not supporting detection linkage is removed, but utilize the adapter plate of the expansion plate of former machine as detecting sensor, the every detection of sensor once must move once and prop up with cigarette and contact once like this, long-term so high-revolving contact, sensor end is easy to wearing and tearing, is subjected to the influence of kinematic accuracy simultaneously, all is subjected to bigger influence in the accuracy of detection of sensor and service life; Secondly since reject valve and reject the valve distance far away, simultaneously for fear of with motion in expansion plate produce and interfere, therefore tracheae is longer, easily bending, atmospheric pressure lost and less stable, effect is rejected in influence, even can stifled cigarette phenomenon take place in the rejecting process because the air pressure deficiency causes; The 3rd, dismounting inconvenience in carrying out equipment time-based maintenance and maintenance process, and need debugging repeatedly just can reach desirable verification and measurement ratio in the installation process, prolonged debugging cycle greatly.
The problems referred to above must solve as early as possible, to improve accuracy of detection, reduce the parking probability, the convenience that raising equipment uses.
Summary of the invention
The purpose of this utility model is that to prop up the sensor end that exists in the testing process at current packaging machine list cigarette easy to wear, reject the problem of air pressure shakiness and inconvenient maintenance, design a kind of no motion assembly, with the hard-wired detection efficiency height of sensor, the whole integrated form list of easy maintenance and installation props up bear and detects device for eliminating.
The technical solution of the utility model is:
A kind of whole integrated form list props up bear and detects device for eliminating, it comprises the rejecting valve 2 of a plurality of detecting sensors 1 and same quantity, it is characterized in that described detecting sensor 1 and reject valve 2 being fixedly mounted on the mount pad 3, and detecting sensor 1 is positioned at the top of cooresponding rejecting valve 2, mount pad 3 is installed in down a side of cigarette channel 4, each detecting sensor 1 is electrically connected with the circuit card that is installed in circuit card case 5, each is rejected valve 2 and links to each other with the outlet side of cooresponding electromagnetic gas valve 7 by tracheae 6, electromagnetic gas valve 7 is installed in the solenoid valve box 8 and with pressure gas source and links to each other, solenoid valve box 8 is installed on the aforesaid mount pad 3, described circuit card case 5 is installed in the bottom of solenoid valve box 8, on the font lower shroud 9 of the following other end of cigarette channel 4, be provided with detected cigarette propped up the gas hole 10 that blows to sensor one side with detecting sensor 1 relative height place, described font lower shroud 9 with reject valve 2 opposite position places and be provided with and reject passage 11.
Be provided with the anti-smoke hole 12 of taking in the rejecting passage 11 on the described font lower shroud 9.
Link to each other with source of the gas by deflecting plate at described each electromagnetic gas valve 7, the inlet end of each electromagnetic gas valve 7 links to each other with the cooresponding outlet side of deflecting plate, and the inlet end of deflecting plate links to each other with source of the gas.
The utlity model has following advantage:
The utility model is by removing the expansion plate of out-of-action former machine (GD wrapping machine), directly detecting sensor and rejecting nozzle are installed in and are fixed in a side of cigarette channel down on the same mount pad, the wear problem of sensor head and the repetitive positioning accuracy problem of motion have been solved, can improve the accuracy rate of detection greatly, satisfy the requirement of user recall rate.
In order to improve the accuracy rate of detection, the utility model is also by setting up gas hole on smoke deflector, makes end that cigarette props up and the distance between the sensor all the time within the optimum detection distance.
Owing to there is not movable parts, the distance between electromagnetic gas valve and the nozzle further shortens simultaneously, has improved the success ratio of rejecting.
Because all parts are installed on the mount pad, only need during dismounting mount pad is pulled down and whole detection device can be pulled down, only need when reinstalling that mount pad is installed to original position and can need not to adjust.Therefore installation and maintenance is very convenient.
