The goods move forwards on a roller of the roller conveyor, when the goods move between the cutting device and the film grabbing device on the two sides, a scanning system on the conveyor transmits a position signal to a controller of a roller motor, the roller motor stops running, the goods stop between the cutting device and the film grabbing device, and the scanning system acquires information of the goods;
second, thermal cutting
And the master control system automatically calculates and forms motion control parameters of all mechanisms in the driving equipment according to the cargo information obtained by the scanning system. The double-piston rod cylinder B of the cutting device is controlled to move outwards, the cutting mechanism is pushed to the side face of the goods until the outer end face of the supporting rod of the cutting mechanism presses the surface of the thin film, and the thin film on the side part is cut by the electric heating wire; in the process, the pressure of the outer end of the supporting rod on the surface of the film is controlled by a precise air pressure control system; the supporting rod of the cutting mechanism is used for transversely limiting the heating wire, and goods are prevented from being damaged too deeply by cutting of the heating wire.
Thirdly, grabbing the side film
When the packaging film is cut, the driving mechanism of the film grabbing device drives the rotary support above the film grabbing device to rotate, the clamping jaw mechanism is adjusted to the side face facing the goods, the two jaw bodies at the outer end of the clamping jaw mechanism are driven outwards to be in contact with the film through the double-piston-rod cylinder A, and the stroke control process of the double-piston-rod cylinder A is similar to that of the double-piston-rod cylinder B. Namely, the travel parameters are automatically calculated in the master control system according to the cargo information obtained by the scanning system. And the piston rod cylinder A is controlled to move outwards according to the control, and two claw bodies at the outer end of the driving claw mechanism are in contact with the film. The pressure of two claw bodies at the outer end of the clamping jaw mechanism on the surface of the film is controlled by a precise air pressure control system.
The piston rods of the clamping jaw air cylinders synchronously push the two jaw bodies to rotate through the connecting rods, the outer ends of the two jaw bodies are closed to clamp the thin film, and finally the clamped thin film is pulled down through the synchronous action of the double-piston rod air cylinder A and the driving mechanism and is placed into the thin film crusher on one side, so that the packaging thin film on the side surface of the goods is automatically removed, and the fixing of the end cover type packaging film on the upper part of the goods is released;
fourthly, removing the top packaging film
The lifting mechanism of the film suction device drives the sucker support and the sucker component to move upwards until the sucker component is higher than the upper surface of a cargo, then the sucker support and the sucker component are driven by the rotary cylinder to rotate to the top of the cargo, the lifting mechanism drives the sucker component to move downwards, the sucker is tightly pressed on the end cover type packaging film and tightly sucked, then the sucked end cover type packaging film is upwards pulled down from the top of the cargo through the lifting mechanism, and finally the rotary cylinder drives the sucker component to rotate outwards to place the packaging film on the upper portion into the film crushing device for crushing, so that the film dismantling of the end cover type packaging film on the upper portion of the cargo is completed. The whole process of the membrane detaching process does not need the participation of workers, the membrane detaching efficiency is high, and the production cost of enterprises is favorably reduced.
When the lower edge of the end cap type packaging film extends downwards for a long time, the following steps are added in the second step or between the third step and the fourth step
Corner cut
Adjusting the heating wires according to the goods information obtained by the scanning system, sequentially adjusting the heating wires to be close to four edges of the goods for vertical cutting, and cutting contact parts of the end cover type packaging film and the four edges of the goods;
because the corner of the end cover type packaging film is wrapped at the top corner of the goods, in the process that the end cover type packaging film is pulled down from the top of the goods in the fourth step, if the lower edge of the end cover type packaging film extends downwards for too long, the top corner at the upper end of the goods can be hung in the wrapping corner formed by the end cover type packaging film, the friction force between the end cover type packaging film and the goods is increased, the film-detaching resistance of the end cover type packaging film is increased, the problem that the resistance of the end cover type packaging film is not overcome by the suction force of the suction disc can occur, the suction disc and the end cover type packaging film are separated from each other in a falling mode, and the end cover type packaging film cannot be sucked down.
After the step of increasing this corner cut, just can avoid when tearing open the membrane the apex angle of goods hang the problem of the parcel angle of end cover formula packaging film medial surface, guarantee that the sucking disc can easily be inhaled end cover formula packaging film.
The photoelectric sensor in the material guide opening of the film crusher can sense the stacking state and the number of the cut films in the material guide opening, and when the number of the cut films reaches the set number, the control system automatically starts the film crusher to crush the films.
