One, technical field
The present invention relates to particularly splicing technology of cigarette processing industry filter stick production technology.
Two, background technology
Cigarette filter rod processes by filter-stick forming device, and the splicing operation when changing paper is a key link in the filter stick production process, and the splicing method of operating of filter-stick forming device is at present:
The first step: change paper and prepare
When being reduced to when setting value at diameter on the paper frame with paper disc, along the automatic Rotate 180 of traffic direction paper frame of paper °, make with paper disc position and stand-by paper disc location swap, while set bidirectional relay installs new paper disc.
Second step: main motor reduction of speed
When continuing to be reduced to the bottom line setting value with the paper disc diameter, system sends the splicing signal, and main motor is reduced to predefined connection speed and time-delay by speed of production.
The 3rd step: simultaneously operating
Tensile strength at paper allows under the prerequisite, and quickening roller provides constant pulling force that new paper disc is accelerated to connection speed, makes synchronous with paper and stand-by paper.
The 4th step: bonding operation
The electromagnet that has double faced adhesive tape in the jockey moves rapidly, to bond together with obbbin and stand-by obbbin, new paper disc before automatic simultaneously cut-out is positioned at the old paper disc residue paper after the adhesive spots and is positioned at adhesive spots has been exported paper, meanwhile microswitch sends accumulative total pulse " beginning " signal to the splicing supervising device, and the control bidirectional relay resets and prepares splicing next time.
The 5th step: prismatic rail contact removing filter-stick
Filter stick enters the prismatic rail after make-up machine loudspeaker mouth place is cut into the scale section, the splicing supervising device of receiving " beginning " signal begins to calculate the umber of pulse of pulse transducer, when umber of pulse equates with setting value, prismatic rail place magnetic valve is connected, blow out several filter sticks, guarantee and to contain the contact removing filter-stick of double faced adhesive tape.
The 6th step: reply speed of production
Behind the contact removing filter-stick, main motor delay time and raising speed to speed of production, finish splicing operation.
At present filter stick production splicing method is owing to adopt the splicing of lifting speed, causes to change the filter stick of producing in the paper process and have the resistance to suction fluctuation, influences product quality; In addition, the fixed point of prismatic rail place scale filter stick reject operation not only to filter stick cut off with pulse detection between cooperate require high, and height is consumed the parts filter stick press the requirement of protecting hairbrush also very high, be easy to filter stick to occur and squeeze card race bar phenomenon and frequent the parking, aggravated the resistance to suction fluctuation of filter stick in this link.
Three, summary of the invention
The purpose of this invention is to provide a kind of non-deceleration splice paper production technique of cigarette filter stick forming machine, solve the filtering rod fluctuation that causes because of the splicing operation in the present filter stick production, cause the generation of shutting down phenomenon because of filter stick squeezes card when stopping to reject.
For realizing above purpose, technical solution of the present invention is to utilize existing filter stick formation machine equipment, the method that paper splicing overall process speed of production is invariable, contact removing filter-stick position is changed to position of cigarette-dividing wheel from filter-stick forming device prismatic rail is changed in employing, and according to the action request of each executing agency of filter-stick forming device filter-stick forming device is carried out Programmable Logic Controller (being called for short PLC) and transform, whole splicing process is finished by following four steps.
The first step: change paper and prepare
When being reduced to when setting value with the paper disc diameter on the paper frame, along the automatic Rotate 180 of traffic direction paper frame of paper °, the PLC program start installs new paper disc.
Second step: simultaneously operating
When being reduced to the bottom line setting value with the paper disc diameter, system sends the connection signal, and quickening roller provides constant pulling force that new paper disc is accelerated to connection speed.
The 3rd step: bonding
Action is bonding with new obbbin with old obbbin rapidly for the electromagnet of band double faced adhesive tape in the jockey, and PLC begins the accumulative total pulse signal simultaneously.
The 4th step: fluted drum contact removing filter-stick
PLC calculates the umber of pulse of pulse transducer, and when umber of pulse equated with setting value, the position of cigarette-dividing wheel magnetic valve was connected, and blows out several filter sticks, and the contact filter stick of guaranteeing to contain double faced adhesive tape is disallowable, and while PLC internal reset is prepared next splicing and operated.
Because fluted drum just was provided with originally and comprises the grey cleaning device of blowing of gas hole,, can realize the operation of fluted drum contact removing filter-stick so do not need it is carried out parts increase and decrease or transformation.
Adopt the technology of the present invention to produce filter stick, thoroughly eliminated, guaranteed constant product quality because of changing the filtering rod fluctuation that paper splicing operation causes and causing the frequent shutdown phenomenon because of filter stick squeezes to block when rejecting.Because the present invention need not filter-stick forming device is carried out machine rebuilding when implementing, paste position and executing agency are constant, set by PLC actuation time, rejecting signal produces by PLC is inner, and transform according to the PLC that each executing agency's action request carries out filter-stick forming device is the technological transformation that the colleague technical staff all implements easily, the improved filter-stick forming device of PLC has promoted automation degree of equipment and performance accuracy, thereby implementation cost is low, effective, is easy to promote.
Four, the specific embodiment
Below in conjunction with the specific embodiment the present invention is described in further detail.
Just utilize filter-stick forming device to produce the cigarette filter stick, main motor reduces speed of production and pastes the method that the main motor raising speed in back returns to ordinary production speed change existing splicing when changing the paper splicing before, adopt the invariable splicing method of splicing overall process speed of production, and contact removing filter-stick position is changed to position of cigarette-dividing wheel from the prismatic rail of filter-stick forming device, utilize the original air blowing cleaning mechanism of fluted drum will be with the removing filter-stick of contact, action request according to each executing agency of filter-stick forming device carries out the PLC transformation to filter-stick forming device again, substitute the hardware time order circuit of former machine with the software sequential of PLC, reject the step-by-step counting of operation and adopt the high-speed counter of PLC to replace former splicing supervising device counting, whole splicing process is finished by following four steps.
