[0029] Reference Figure 1-6 An automated bundling device for foam boards includes a frame 1, on which a stacking platform 14, a belt conveyor 7 and a bundling platform 2 are installed from right to left. The upper surfaces of the stacking platform 14, the belt conveyor 7 and the bundling platform 2 are flush, and the stacking, transporting and bundling processes can be automatically realized.

[0030] A top plate 3 is also installed on the frame 1. An annular plate 15 is fixedly installed on the bottom of the top plate 3 at the position corresponding to the stacking platform 14. The bottom of the annular plate 15 is rotatably connected to a swivel 24. A plurality of adsorption plates 21 that can move up and down are elastically installed on the bottom of the swivel 24 in the circumferential direction. The top of the adsorption plate 21 is elastically installed on the bottom of the swivel 24 by a spring 23. The plurality of adsorption plates 21 are arranged at equal intervals. The plurality of adsorption plates 21 can be repeatedly transferred to realize the stacking process.

[0031] A first cylinder 20 is installed on the right side of the annular plate 15. The telescopic end of the first cylinder 20 passes through the annular plate 15. A through hole 25 is provided on the rotating ring 24 at a position corresponding to the adsorption plate 21 for the telescopic end of the first cylinder 20 to pass through. When the first cylinder 20 is started, the telescopic end of the first cylinder 20 passes through the corresponding through hole 25, and then moves down against the adsorption plate 21 at the right end to perform the adsorption process.

[0032] A main pipe 17 is rotatably connected to the top plate 3. A motor 19 is installed on the top plate 3. The output shaft of the motor 19 is connected to the main pipe 17 through a pair of gears 18. The lower end of the main pipe 17 extends into the annular plate 15 and is fixedly connected to a plurality of branch pipes 28. The plurality of branch pipes 28 correspond one to one with the plurality of adsorption plates 21. The ends of the plurality of branch pipes 28 are fixedly connected to the inner side of the swivel 24. A plurality of suction cups 22 are provided at the bottom of the adsorption plate 21. The plurality of suction cups 22 are connected to the corresponding branch pipes 28 through connecting pipes 29. Solenoid valves 30 are installed in the plurality of branch pipes 28. An air pump 16 is installed on the top plate 3. The air outlet end of the air pump 16 is connected to the top of the main pipe 17 through a rotary joint.

[0033] A conductive head 27 electrically connected to the solenoid valve 30 is provided on the multiple branch pipes 28. A non-closed circular conductive rail 26 cooperating with the conductive head 27 is installed at the bottom of the annular plate 15. The disconnected end of the non-closed circular conductive rail 26 is located above the guide pushing mechanism. The non-closed circular conductive rail 26 is externally connected to a power supply. During the transfer of the foam board, the conductive head 27 always contacts the non-closed circular conductive rail 26, so that the solenoid valve 30 is always in an open state, and the foam board is transferred to the left end. The corresponding solenoid valve 30 is closed, and the conductive head 27 moves to the disconnected position of the non-closed circular conductive rail 26.

[0034] A guide pushing mechanism is installed on the left side of the stacking platform 14 corresponding to the position of the belt conveyor 7. The guide pushing mechanism includes a second cylinder 13 installed on the stacking platform 14. The telescopic end of the second cylinder 13 is fixedly connected to a push plate 12. The pushing direction of the push plate 12 corresponds to the belt conveyor 7. The guide pushing mechanism also includes a sorting component. The sorting component includes a mounting groove arranged on the stacking platform 14. A double-headed cylinder 11 is installed in the mounting groove. The two telescopic ends of the double-headed cylinder 11 are fixedly connected to a sorting plate 10. The tops of the sorting plates 10 extend out of the mounting grooves. Starting the double-headed cylinder 11 drives the two sorting plates 10 to move toward each other, so that the stacked foam boards can be aligned in the length direction. Then starting the second cylinder 13 drives the push plate 12 to move. On the one hand, the stacked foam boards can be aligned in the width direction. On the other hand, the stacked foam boards can be pushed onto the belt conveyor 7.

[0035] On both sides of the strapping platform 2, strapping machines 6 that can move toward each other are installed. A back plate 5 that can move up and down is installed at the position of the bottom of the top plate 3 corresponding to the strapping platform 2. The third cylinder 4 is started to drive the back plate 5 to move downward and press against the middle position of the foam board. The top plate 3 is installed with a third cylinder 4, and the telescopic end of the third cylinder 4 is fixedly connected to the back plate 5. A double-headed hydraulic cylinder 8 is installed on the frame 1. The two telescopic ends of the double-headed hydraulic cylinder 8 are fixedly connected to the strapping machine 6 on the corresponding side. A plurality of rollers 9 are installed at the bottom of the strapping machine 6. The double-headed hydraulic cylinder 8 is started, and the two strapping machines 6 are driven to move toward each other at the same time, so that the two ends of the foam board enter the strapping mechanism of the strapping machine respectively, and the strapping process of the two ends of the foam board can be completed at the same time.

[0036] The foam board discharged from the foam molding machine is sent to the right end of the stacking platform 14, and the first cylinder 20 is started. The telescopic end of the first cylinder 20 passes through the corresponding through-hole 25, and then moves down against the adsorption plate 21 at the right end, and the air pump 16 is started. Air is sucked through the main pipe 17, multiple branch pipes 28 and connecting pipes 29, and then the foam board can be adsorbed through multiple suction cups 22. Then, the adsorption plate 21 is reset under the action of the spring 23, and the motor 19 is started. The main pipe 17 is driven to rotate through a pair of gears 18, and then the swivel 24 is driven to rotate along the annular plate 15 through multiple branch pipes 28. During the transfer of the foam board, the conductive head 27 always contacts the non-closed circular conductive rail 26, and the solenoid valve 30 is always in the open state, and the foam board is transferred to the left end. The corresponding solenoid valve 30 is closed (at this time, the conductive head 27 moves to the disconnected position of the non-closed circular conductive rail 26), the negative pressure disappears, and the foam board falls to the left end of the stacking platform 14. The multiple adsorption plates 21 provided can be repeatedly transferred to realize the stacking process.

[0037] Starting the double-headed cylinder 11 drives the two sorting plates 10 to move toward each other, which can align the stacked foam boards in the length direction. Then starting the second cylinder 13 drives the push plate 12 to move. On the one hand, it can align the stacked foam boards in the width direction, and on the other hand, it can push the stacked foam boards to the belt conveyor 7, and then the belt conveyor 7 transfers them to the bundling table 2.

[0038] When the foam board is delivered to the strapping table 2, the third cylinder 4 is first started to drive the supporting plate 5 to move downward and press against the middle position of the foam board. The two ends of the foam board extend out of the two sides of the strapping table 2 respectively. At this time, the double-headed hydraulic cylinder 8 is started to drive the two strapping machines 6 to move toward each other, so that the two ends of the foam board enter the strapping mechanism of the strapping machine respectively. The strapping process of the two ends of the foam board can be completed at the same time without manual rotation and multiple strapping.
