Position transduser 232a, 232b, 232c, 232d etc. also are arranged on the below of axis of rolling row.
The concrete principle of work of full automaticity reason box machine 2 is following:
After machine power (not shown) was opened, feedway 1 was sent packing box into the axis of rolling and is listed, and the motor-driven axis of rolling 210 rotates, and moved forward thereby drive packing box.Position transduser is the position that is used for detecting packing box, and gives Programmable Logic Controller PLC (not shown) with information transfer, driving the pin of pin cylinder 240 control back.The initial position of pin is: pin 216a, pin 216b, pin 216c, pin 216d do not work, and are in the axis of rolling 210 belows, and pin 216e jack-up is in running order.
Packing box is arranged through out-of-date on the axis of rolling 210, each position transduser and the 240 meeting relevant works of pin cylinder:
If packing box gets into and moves at the axis of rolling 210 from box-inlet 226, when packing box during through second station 220, position transduser 232c detects has box, pin 216a jack-up (guaranteeing can only have a box packing box in 1 position transduser detection range).If packing box was just arranged above the 3rd station 222 originally, that pin 216c is jack-up, and the packing box on second station 220 can only stay on second station 220 and wait at this moment; If opposite, there is not packing box on the 3rd station 222, the packing box on second station 220 of this moment can continue to move forward and get into the 3rd station 222.At this moment, when position transduser 232c had not had packing, pin 216a fell the packing box that makes first station 218 automatically and gets into second station 220.Position transduser 232e on the 3rd station 222 detects has box, and the automatic jack-up of pin 216c is because pin 216e is in the jack-up state always, so packing box can only stay on the 3rd station 222.If packing box gets into from box-inlet 228, its principle is the same.
If; On position transduser 232e on the 3rd station 222 and position transduser 232f, packing box is arranged all; Then this moment, pin 216c and pin 216d were in the jack-up state, and pin 216e falls (prerequisite is that feeding table position transduser 232g and position transduser 232h go up no packing box).Two packing boxes on the 3rd station 222 are moved to feeding table 214 simultaneously.When the position transduser 232g on the feeding table 214 and position transduser 232h detect packing box, the automatic jack-up of pin 216e.When the packing box on the 3rd station 222 moves to feeding table 214; The 3rd station 222 upper position sensor 232e and position transduser 232f detect no packing box; Pin 216c and pin 216d fall immediately, make the packing box of second station 220 get into the 3rd station 222 smoothly.
If, on gas-control packing device 3, do not have packing box, and feeding table 214 there is box, draw 218 work of box cylinder, the packing box of feeding table 214 is entered on the wrapping machine.If on position transduser 232e and the position transduser 232f packing box is arranged all on the 3rd station 222, pin 216e falls, and the packing box on the 3rd station 222 moves to feeding table 214, successively circulation.
If; When all packing box being arranged on position transduser 232c, position transduser 232d, position transduser 232e, position transduser 232f, position transduser 232g, the position transduser 232h; And packing box is arranged on any position transduser among position transduser 232a and the position transduser 232b, belt conveyor 212 stops into box automatically.
Put box or many few on one side on one side when belt conveyor 212 single limits, packing box gets into reason box machine just needs reason box automatically, to practice thrift the wait time of gas-control packing device 3.Still is example with box-inlet 226: when box is all arranged on position transduser 232a, position transduser 232c, the position transduser 232e or with regard to position sensor 232c, position transduser 232e on box is arranged; And position transduser 232b, position transduser 232d go up and do not have packing box on no packing box or position transduser 232b, position transduser 232d, the position transduser 232f; At this moment pin 216b and the automatic jack-up of pin 216d; Reason box cylinder 223b shifts the packing box on the position transduser 232c on the position transduser 232d onto automatically; Manage box cylinder 223b automatic homing then, pin 216b and pin 216d fall automatically.If packing box gets into from box-inlet 228, its principle is the same.
