Description
Technical field
The utility model relates to the carton of cigarette packaging machine and lacks the bag negative-pressure detection device.
Background technology
At present, the subsidiary engine part of each GD of cigarette factory packaging machine, because the technology of the package principle defective tobacco bale occurs inevitably in parcel transparent-paper package process, defective tobacco bale is rejected at CH outlet eliminating system place.Be input to the CT case packing machine by mending the additional tobacco bale of cigarette device then.Though being equipped with, the CT machine lacks bag detection and device for eliminating, but, existing lack bag detect adopt be weigh, detections such as eddy current, quantum, photon, because detecting sensor self design attributes reaches the dependency characteristic to partial supplementary material (aluminium-foil paper), cause its stability still unreliable, also have the bag of lacking plume to go into market in the bar bag, lead to quality accident, influence corporate image.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of carton of cigarette packaging machine pollution-free, environment-friendly type to lack the bag negative-pressure detection device, stop to cause the quality accident of scarce bag in carton of cigarette packing link, and stable work in work, reliable, efficient.
The purpose of this utility model is achieved through the following technical solutions:
The carton of cigarette packaging machine lacks the bag negative-pressure detection device, comprises that one lacks the bag test section by upper and lower plate and the moulding storehouse that folders constituted, that is clipped between the left and right end of upper and lower plate; It is characterized in that: described scarce bag test section comprises detection of negative pressure unit, moulding storehouse, PLC Programmable Logic Controller; Detection of negative pressure unit, moulding storehouse comprises that correspondence is opened in the center airway between the upper and lower plate two ends and is located at pore, vacuum generator, the negative pressure transducer that is communicated with corresponding center airway on the upper and lower plate opposite face respectively, the one corresponding end sealing of two center airways, the other end connect a gas circuit, and two gas circuits also connect the back by air pipe connection vacuum generator; Described negative pressure transducer is installed on the air pipe and with the PLC Programmable Logic Controller and links to each other.
The center airway of described upper and lower plate is connected with air pipe by a four-way Connection Block, this four-way Connection Block is packed on the moulding storehouse of center airway openend one side, and peg graft respectively described center airway openend, main interface of two air-path interface connects vacuum generator by pipeline; Described negative pressure transducer is fixed on the four-way Connection Block and its sensing head stretches in another gas circuit of four-way connection.
The principle of work of above-mentioned scarce bag negative-pressure detection device is: the CT moulding storehouse that enters the mouth is adapted as detection of negative pressure moulding storehouse, and utilizes a negative pressure transducer to detect the negative pressure value of air pipe in real time.When the tobacco bale arrangement enters the moulding storehouse, solenoid valve is opened, positive pressure air produces negative pressure air by vacuum generator, under intact bag situation, all pores are crossed plug by tobacco bale, form subnormal ambient in the moulding storehouse, and under scarce bag situation, the pore that lacks on the package location is open state, can't form subnormal ambient in the moulding storehouse; The PLC Programmable Logic Controller detects negative pressure value in real time to negative pressure transducer and handles, and judges whether it is qualified, and substandard product will be rejected a mouthful rejecting at CT bar bag.
Above-mentioned carton of cigarette packaging machine lacks the bag negative-pressure detection device, has following beneficial effect:
This negative-pressure detection device does not have specific (special) requirements to starting material, and particularly the tobacco bale product of 1/5 aluminium paper of good harvest use and spraying wrapper all can not finely detect with original scarce package detection device, uses the scarce bag detection of this negative pressure and can both realize fully detecting; Have to reject mouthful to reject automatically and do not conform to the glazing bar packet function, can also save bar bag tracing paper with respect to rejecting mode in CV machine location detection at CT; The position of this transformation has no effect to the parcel beauty care device device (comprising separate type) that each cigarette factory is installed additional in CT moulding storehouse; Do not need manually to reach fall vacant bag do not conform to the glazing bar bag, realize not shutting down automatic rejecting, improve machine effective operation rate.This device is easy to use, and stable performance, reliable reaches the detection effect of desired design.This device is a kind of pollution-free, environmentally friendly machine, is that cigarette factory stops to cause the technological transformation first-selection that lacks the bag quality accident in the packing link.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a perspective view of the present utility model.
Fig. 2 is the component decomposition map (comprising negative pressure transducer and four-way Connection Block) of Fig. 1.
