SU133590A1 - Method for sorting laminated sheets - Google Patents

Description

The production technology of pressed laminated plastics is known for multi-storey hydraulic presses with gasket sheets made of stainless steel, and all operations for disassembling compressed bags, sorting sheets by thickness and placing them into racks are done manually.

The proposed method of disassembling the packages after pressing and COD thickness sheet thickness with their placement in the respective stores eliminates manual labor and provides for the complete mechanization and automation of these processes.

FIG. Figure 1 shows schematically an assembly that serves to carry out the described method; in fig. 2 - air spreader sheets.

The main assemblies of the unit are receiver U and pneumatic spreader 2 (Fig. 1). The receiver is a conventional double-chain conveyor equipped with forks 3. Having the ability to rotate on axis 4 by means of a pneumatic actuator 5, the receiver alternately takes either a vertical or horizontal position.

Pressed together with stainless steel packing sheets on a hydraulic multi-floor press 5, packs of 7 plastic sheets are pushed onto the receiver / which is at this moment in a vertical position. The receiver is then placed in a horizontal position by means of a pneumatic actuator 5 together with the packages and vibrated by the vibrator 8. Being located between the forks in a vertical position under the influence of vibration, the packages of plastic sheets are peeled off from the gasket sheets. After the vibration, the packets are alternately moved by the receiver under the air spreader 2.

Air spreader 2 moves freely over beam 9 and stops at three fixed positions, /, // and ///.

Air spreader 2 (Fig. 2) includes a carriage 10 freely moving along beam 9. The lower part of the carriage is rigidly connected to the pneumatic cylinder 11, through which the piston 12 moves. The lower end of the piston rod is equipped with a rubber suction cup 13, inside which is mounted a sensor 14 and an elastic contacts 15.

Being in the position of / (Fig. 1), the air spreader sucks from the sheet below it. If it is a gasket sheet, then it closes the elastic contacts, and the air spreader, having received the corresponding impulse, automatically moves to a fixed position (A) where, being freed from the vacuum in the suction cup, puts the gasket sheet in the foot 16 and automatically returns to its original position /. Here again, the next sheet is sucked.

If the sheet is pressed plastic, the elastic contacts 15 will not close and the carriage will automatically move to a fixed position ///. Here, the sheet is lowered onto table P, equipped with sensor 18, and will be between contacts 19 and 20 of two induction sensors 14 and 18, transmitting pulses to a special device that automatically prints a sheet of plastic its thickness in thickness and opens the magazine flap for placing sheets corresponding thickness.

At the same time, a pulse is applied to the actuator to return the air spreader to the initial fixed position.

Subject and 3 oreteni

A method of sorting sheets of laminated plastics when they are pressed using a vibrator and vacuum suction cups, characterized in that, in order to automate the sorting of sheets of laminated plastics in thickness, electrical impulses of sensors from the measuring device are used that act on the die drive to put its thickness on the plastic sheet and simultaneously opening the door of the magazine for this sheet thickness.
