Description

Technical Field

[0001] The present invention relates to the technical field of automatic packaging of certificates of conformity, and in particular to an automatic packaging device for certificates of conformity. Background Art

[0002] When many objects are packed, the corresponding certificates are first placed in the box. The certificates can be placed in the box after the objects are packed and before the boxes are sealed, or they can be placed in the box before the objects are packed. The existing automatic packing device for certificates directly uses a paging machine to drop the corresponding certificates directly downward into the transport box, but this method still has certain shortcomings: for lighter certificates, they are easy to fall to a position outside the box if they fall directly. At the same time, the movement of the box and the airflow generated by the operation of the structure near the certificate will also affect the precise placement of the certificate. For this reason, we propose an automatic packing device for certificates to solve the above problems. Summary of the invention

The setting of the one-way bearing 33 makes the gear rack 30 drive the round rod to rotate only when it moves up, and the gear rack 30 will not drive the round rod 32 to rotate during the downward movement; the lifting and transformer component is used to control the up and down movement of the sealing disk 27, and the sealing disk 27 can be used to realize the suction or deflation of the suction cup 26 during the up and down movement, thereby satisfying the absorption of the certificate 8 and the release after moving to the box body 6.

[0026] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0027] In the present invention, when the box body 6 moves to a suitable position, the conveying roller 5 stops running, and the servo motor 9 is turned on; The servo motor 9 drives the shaft 12 to rotate through the cooperation of the one-way bearing 2 13 and the gear 1 14. At this time, the one-way bearing 2 13 is in a self-locking state, the one-way bearing 1 is in a rotatable state, and the reciprocating screw 10 does not rotate; the rotation of the shaft 12 drives the reciprocating screw 20 to rotate through the cooperation of the two bevel gears 17, and the reciprocating screw 20 rotates through the lifting block 21 and the connecting rod 22 to drive the elastic telescopic tube to move downward, and the elastic telescopic tube moves downward to drive the suction cup 26 to move downward, so that the suction cup 26 first contacts with the certificate 8, and then moves downward mechanically to shrink the elastic ring 24. In this process, the hard tube 23 moves downward relative to the bottom 25 of the tube, and then through the gear Wheel 2 34 and one-way bearing 3 33 drive round rod 32 to rotate, and the rotation of round rod 32 drives rotating rod 35 to rotate a certain angle through bevel gear 2 36 (as shown in the figure, there are four magnetic blocks 37, and rotating rod 35 rotates 90 degrees at this time), so that magnetic block 1 37 rotates to the next adjacent position. At this time, the magnetic force on sealing disk 27 is converted from the initial repulsive force to suction force, thereby causing magnetic block 1 37 to move upward. The upward movement of magnetic block 1 37 increases the space between magnetic block 1 37 and suction cup 26, generating the required negative pressure, and using the negative pressure to enable suction cup 26 to stably absorb certificate 8. When lifting block 21 moves to the lowest position, the suction force generated is the largest. When the lifting block 21 moves from the lowest position to the highest position, it will drive the elastic telescopic cylinder, the suction cup 26 and the certificate 8 to move upward together. During this process, the elastic ring 24 will be reset, but the space increased by its reset is still sufficient to absorb the certificate 8 compared with the negative pressure generated by the upward movement of the sealing disk 27; When it moves up to the highest point, the rotation direction of the driving end of the servo motor 9 is changed. At this time, the shaft 12 stops rotating and the reciprocating screw 10 starts rotating. The rotation of the reciprocating screw 10 drives the reciprocating screw 20 and the corresponding structure installed thereon to move together through the shaft 12. When the certificate 8 moves to the top of the box 6, the distance between the moving block 11 and the servo motor 9 is the largest. At this time, the elastic telescopic cylinder is changed to make the shaft 12 work, the reciprocating screw 10 stops rotating, and the shaft 12 rotates, first making the certificate 8 contact with the bottom wall of the box 6, and then continue to move down, so that the magnetic force relationship of the sealing disk 27 changes from attraction to repulsion, and then the suction cup 26 releases the suction on the certificate 8, so that the certificate 8 is safely placed in the box 6, and then when the suction cup 26 moves to the highest point, the reciprocating screw 10 rotates and resets as a whole.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
