Technical Field

The invention belongs to the field of paperboard production, and particularly relates to a paper stack overturning and stacking device and method.

Background

The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art.

In the production process of corrugated boards, the corrugated boards need to be stacked into small stacks according to a set number (such as 20 sheets), the small stacks are stacked into large stacks according to a reverse-positive mode, and a turnover mechanism is needed for realizing the reverse placement of the small stacks.

The inventor finds that the turnover mechanism on the market at present adopts a turnover frame or a turnover fork, and after turnover, the upper surface and the lower surface of a paperboard are reversed and then are conveyed forwards continuously, so that the turnover mechanism has the following defects: the number of times of placing on the big paper buttress is placed to follow-up little paper buttress does not reduce, and the cardboard generally upwarps, becomes the perk down after the upset, and the cardboard that sticks up down easily causes to bore into conveying roller clearance or belt linking department to block up in transportation process, and the higher authority of cardboard is the printing face, and the printing face is under after the upset, easily causes the printing face fish tail in the transportation process.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a paper stack overturning and stacking device and a paper stack overturning and stacking method, and the device can solve the problems that a paperboard is generally upwards warped and becomes downwards warped after overturning, and the downwards warped paperboard is easy to enter a conveying roller gap or block a belt joint in the conveying process.

In order to achieve the purpose, the invention is realized by the following technical scheme:

in a first aspect, the technical scheme of the invention provides a paper stack overturning and stacking device which comprises a stack inlet belt, a stack outlet belt, an overturning mechanism and a positioning baffle, wherein the stack outlet belt is provided with the positioning baffle to prevent a paper stack from moving; a turnover mechanism is also arranged above the stack outlet belt and can turn over by taking the rear side of the turnover mechanism as an axis; the turnover mechanism comprises a first supporting part and a second supporting part which are arranged in parallel; the first supporting part is also connected with the first supporting plate and the second supporting plate.

As a further technical solution, the first supporting part is slidably connected with the first supporting plate, and the first supporting plate can rotate relative to the first supporting part; the second supporting plate is rotatably connected with the first supporting part; the second supporting plate is closer to the rear side of the turnover mechanism relative to the first supporting plate.

As a further technical scheme, the first supporting plate is also connected with a belt transmission mechanism.

As a further technical scheme, the first supporting plate is connected with a sliding block, and the sliding block is matched with a sliding rail on the first supporting part; the slider is still connected with first pneumatic element, and the stiff end of first pneumatic element is connected in the slider, and the flexible end of pneumatic element passes through the tip of connecting piece connection first layer board.

As a further technical scheme, the end part of the second supporting plate is connected with a second pneumatic element through a connecting piece, and the fixed end of the second pneumatic element is connected to the first supporting part.

In a second aspect, the present invention further provides a paper stack turning and stacking method, using the paper stack turning and stacking apparatus of the first aspect, the paper stacks ordered as odd numbers are directly transferred to the stack-out belt, and the paper stacks ordered as even numbers are turned over by the turning mechanism and then fall on the previous paper stack ordered as odd numbers, and then the resultant double-layer paper stack continues to move backwards.

The technical scheme of the invention has the following beneficial effects:

1) in the invention, the paper stacks sequenced in odd number are directly transferred to the stack-out belt and are blocked and positioned by the positioning baffle plate positioned on the stack-out belt, while the paper stacks sequenced in even number are turned over by the turning mechanism and then fall on the previous paper stack sequenced in odd number, and then the synthesized double-layer paper stack continues to move backwards.

2) In the invention, the side edge of the first supporting part is also provided with a side edge belt transmission mechanism so as to move the supporting plate.

3) In the invention, in the operation process, two stacks are combined into one stack in a reverse and forward mode, so that the stacking efficiency of the subsequent large stack is improved; after the paper stacks are combined into a stack, the printing surface is not contacted with the conveying component, the printing surface is protected from being damaged, and the subsequent paper stacks are conveyed to avoid blocking of the lower warping paper plates.
