Description

Technical Field

[0001] The utility model relates to a single-board automatic loading and stacking device, belonging to the technical field of auxiliary mechanical equipment. Background Art

[0002] In the fiberboard industry, large-sized boards (with dimensions of 2400mm×4930mm or larger) are produced by a press, and after sanding and sawing processes, they are made into small-sized semi-finished products and given to customers. The quality of automatic loading in the sanding and sawing processes of large boards is directly related to the breakage rate of the boards.

[0003] In the sawing process, a fork squeegee has always been used to push multiple boards onto a book stacking table at once. When stacked to about 15 - 20 cm, it forms a book stack and flows into the next sawing process.

[0004] Since the thickness of a single board is only 2 - 3 mm, the force point of the squeegee on the board edge or the frictional force of the board may vary, and the number of boards scraped each time is not the same. More seriously, when there are only a few remaining boards, due to the small total thickness, the squeegee cannot well control the height to distinguish the product and the protection board, which may cause damage to the remaining boards or scrape the protection board into the book stack and saw it off. Therefore, more often, it is simpler and more practical for workers to go to the site to pull the remaining few boards. Since workers operate on a lifting platform on-site, there are great safety hazards, and it is not suitable for industrial production needs. It is urgent to transform and implement a complete loading scheme for the remaining boards.

[0005] Therefore, it is necessary to design a single-board automatic loading and stacking device. When there are enough loading boards, the original push board squeegee is used to scrape multiple boards for feeding, and the remaining few boards are completed by using this single-board automatic loading and stacking device. This not only reduces potential safety hazards to personnel, decreases the breakage rate of the boards, achieves the expected effect, but also improves labor productivity. Summary of the Invention

In this embodiment, the stacking table 91 is adapted to receive the fed boards. When the boards on the stacking table 91 are stacked to about 15 - 20 mm to form a book stack, this book stack is then fed into the next sawing process. The upper roller lifting driving member 921 drives the upper roller 922 to move up and down to adjust the distance from the lower driving roller 923, thereby changing the size of the feeding channel 924 to adapt to boards of different thicknesses;

[0064] When a board enters the feeding channel 924, the external motor drives the lower driving roller to rotate clockwise to pull the board onto the stacking table 91.

[0065] Specifically, as Figure 5As shown, the vacuum suction cup assembly further includes a vacuum generator 422, a solenoid valve 423, and a pressure regulator 424. The vacuum generator 422 is connected to the suction cup 421 through a vacuum pipeline.

The push plate motor 71 drives the movable frame 2 to slide on the first cross beam 11 and drives the squeegee 3 to push and convey the plates on the lifting table 8, and conveys a certain amount of plates to the stacking table 91.

[0067] In this embodiment, when there are still a few remaining plates on the lifting table 8, the lifting drive member 414 drives the suction cup 421 to move downward to suck the plate, and then lifts the plate from its original position. The pallet drive member 51 drives the pallet member 52 to move downward and rotates counterclockwise by 90° so that the supporting portion of the pallet member 52 is at the lower end of the tail of the lifted plate to provide support for the plate.

[0068] The push plate motor 71 drives the push plate connecting member 72 to rotate. The push plate gear 73 moves along the rack 12 on the first cross beam 11 to drive the squeegee 3 to move, and conveys the plate to the feeding channel 924 of the auxiliary roller mechanism. The solenoid valve 423 disconnects the vacuum pipeline to release the plate by the suction cup 421. The pallet drive member 51 drives the pallet member 52 to move upward and rotates clockwise by 90° so that the pallet member 52 no longer supports the plate. The plate enters the feeding channel 924 and is clamped by the upper roller 922 and the lower driving roller 923 and then traction-moved to the stacking table 91. The stacking table 91 receives and stacks the plates. The whole process realizes the automatic feeding and stacking of single plates, reduces manual intervention, and improves production efficiency.
