Mode one: in the utility model, the first electronic induction switch and the second electronic induction are just arranged at the below pushing away letter cylinder, are not fixed on and push away letter cylinder.Its Cleaning Principle is: when push away letter cylinder in situ time, push away letter cylinder and block the first electronic induction switch and the second electronic induction switch simultaneously, therefore, the first electronic induction switch and the second electronic induction switch all cannot output optical signals; When pushing away letter cylinder and pushing away forward letter action, the first electronic induction switch is carried on as before and is pushed away letter cylinder and to block and cannot output optical signal, and the second electronic induction switch is not pushed away letter cylinder and blocks and output optical signal; Subsequent time again, when pushing away letter cylinder and resetting backward, the first electronic induction switch and the second electronic induction switch are owing to all being pushed away letter cylinder and blocked and cannot output optical signal; That is, when the second electronic induction switch is output optical signal state by non-output optical signal state-transition, and then when changing again non-output optical signal state into, the moment resetted after pushing away letter cylinder generation action is.
Mode two: in the utility model, the first electronic induction switch and the second electronic induction switch be fixed on push away letter cylinder cylinder barrel on.Its Cleaning Principle is: when push away letter cylinder in situ time, push away letter cylinder and only trigger the first electronic induction switch; When pushing away after letter cylinder pushes away forward letter action, the first electronic induction switch Triggerless, when push away letter cylinder letters group pushed put in place time, trigger the second electronic induction switch; Subsequent time again, when pushing away letter cylinder backward in reseting procedure, the first electronic induction switch and the equal Triggerless of the second electronic induction switch; When pushing away letter cylinder and returning to original position backward, again trigger the first electronic induction switch.That is, when the second electronic induction switch triggering once, push away letter cylinder and just there occurs and once push away letter action.
Apply above-mentioned control setup, the utility model provides a kind of letters plastic package method, comprises the following steps:
Needs are positioned over letters transport platform 1 by many groups of plastic packaging letters group by S1; Wherein, by adjacent two transport platform holder 1-3, one group of letters group is clamped;
S2, PLC starts feed drive motor, under the drive of feed drive motor, make drive member, and then drive transport platform holder 1-3 motion, because letters group is clamped by adjacent two transport platform holder 1-3, make letters group relative to transport platform 1-2 motion thus, realize the transmission to letters group;
Wherein, transmit in letters transport platform 1 in the process of many group letters groups, time initial, make the axial centre of moving system 1-4 be positioned at the center of adjacent two transport platform holder 1-3;
While the described PLC of startup, when described transport platform holder 1-3 being detected by position-detection sensor, namely a notification message is sent to PLC, when PLC receives notification message, simultaneously, when PLC is blocked by the transmission path that the data that photoelectricity opposite type sensor is uploaded draw between photoelectricity opposite type sensor, namely PLC draws to draw a conclusion: there is in the dead ahead pushing panel 1-4-2 the letters group put in place;
Then, PLC makes feed drive motor shut down, and to pushing away letter cylinder 1-4-1 sending action signal;
Push away after letter cylinder 1-4-1 receives this actuating signal, promote to push panel 1-4-2 and travel forward, thus push the letters group put in place the import of sealing machine 2 to; Then, push away letter cylinder 1-4-1 to move backward reset;
By the signal of electronic induction switch, PLC can know that pushing away letter cylinder 1-4-1 resets, then, PLC restarts feed drive motor, restarts to measure after position-detection sensor zero;
By said process, realize the course of conveying each group of letters group being pushed successively to the import of sealing machine 2;
S3, push away in letter course of action at the described letter cylinder 1-4-1 that pushes away, when described PLC knows the film tensioning signal that film degree of tightness sensor 8 uploads, namely PLC sends actuation signal to overlay film drive motor, overlay film drive motor is moved, and then drives film covering device action; Pushed to the process of sealing machine clamping device 2-3 from letters transport platform 1 in letters group, film covering device is to letters group overlay film;
The letters group of film is clamped by sealing machine clamping device 2-3; In addition, push away described in knowing whenever described PLC letter cylinder 1-4-1 push away letter action and reset after, PLC is to sealing cutter actuator sending action signal, sealing cutter actuator drives the downward action of sealing cutter, cut off the film of film covering device output and seal, completing the bonding of the letters group to film, cut-out and capping processes;
S4, the letters group after S3 process, is pushed to heat shrink wrapping machine 3 by the letters group of next batch; In the whole process of heat shrink wrapping machine 3, all use heat shrink wrapping machine clamping device 3-1-2 to clamp letters group, heat shrink wrapping machine 3, to after being carried out pyrocondensation and cooling processing by the letters group clamped, is transported to letters collection table 4;
S5, letters group is delivered to objective by letters collection table 4.
Said process can simply be described as:
After between adjacent two transport platform holders letters group being put letters transport platform, press start button, transport platform holder drives letters group horizontal motion, when move to align with sealing machine clamping device time, the transport platform holder stop motion of letters transport platform, pushes away letter cylinder and the letters group being clamped in letters transport platform is all pushed to sealing machine clamping device, automatically complete and wrap up in film in propelling movement process, after propelling movement puts in place, push away letter cylinder and reset.Sealing cutter is action vertically downward, is bondd by film and cuts off, and sealing cutter resets.Press start button again, letters transport platform and sealing machine do same action, carry out same process to the letters group of different batches.Next batch is wrapped up in letters group that film completes and last batch is wrapped up in the letters group that film completes and push to heat shrink wrapping machine, and the gripper mechanism grips letters group of heat shrink wrapping machine completes thermal contraction, the cooling of film in shrink oven.Letters group after having encapsulated is deposited in letters collection table after heat shrink wrapping machine exports, and staff takes the letters group in letters collection table away.
The letters plastic packaging equipment that the utility model provides and letters plastic package method, have the following advantages:
(1) in letters transport platform, sealing machine and heat shrink wrapping machine, all clamping device is installed, ensure that letters group is not loose in conveying plastic packaging process, solve the difficult problem that the scattered thin pieces of this batch of similar letters can not encapsulate with film automatic heating, make letters not re-use letter box in packaging and transportation, save cost;
(2) degree of automation of whole plastic packaging process is high, letters plastic packaging efficiency is high.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
