Automatic stacker for inspection machine

Abstract

The invention discloses an automatic stacking machine for a printed matter checkout machine. The automatic stacking machine comprises a paper collecting and delivering mechanism. A counting sensor is arranged on one side of the paper collecting and delivering mechanism, a turnover paper blocking mechanism and an aligning mechanism are arranged at the output end of the paper collecting and delivering mechanism, a paper supporting mechanism and a paper pushing mechanism are arranged below the aligning mechanism, and a paper storing mechanism is correspondingly arranged on one side of the paper pushing mechanism; the turnover paper blocking mechanism comprises a paper blocking board with a supporting hook arranged at the bottom, the aligning mechanism comprises aligning boards on the left side, the right side, the front side and the right side, the paper supporting mechanism comprises an inching sensor and multiple paper supporting rods which form a paper supporting plane and move vertically, and the paper pushing mechanism comprises multiple paper pushing rods which form a paper pushing plane and move horizontally and linearly; when located at the upper limit position, the paper supporting plane is close to the aligning boards, and then the paper supporting plane is located at the lower limit position, the paper pushing rods can push a stack of printed matters stacked on the paper supporting plane orderly onto the paper storing mechanism. According to the automatic stacking machine, automatic stacking and aligning speeds of small printed matters are high, stacking is orderly, counting is accurate, paper delivery time is short and work efficiency is improved.

Description

technical field [0001] The invention relates to an automatic stacker for a product inspection machine, which belongs to the field of product inspection machines. Background technique [0002] Currently, if figure 1 As shown, the existing product inspection machine (also known as small-sheet printed product inspection machine) generally includes a paper feeder 10 , a deviation correcting machine 20 , a surface quality inspection machine 30 and an automatic stacker 40 . Such as figure 2 As shown, the automatic stacker 40 includes a delivery mechanism 41. The output end of the delivery mechanism 41 is provided with a pin stopper mechanism 42 and an alignment mechanism. The alignment mechanism includes two side alignment plates 431 With front and back clapping plate 432,433, the below of this clapping mechanism is provided with lateral conveying belt mechanism 44, and the output end side of this lateral conveying belt mechanism 44 is correspondingly provided with unpowered ro...

Problems solved by technology

[0004] As can be seen from the above description, although the existing automatic stacker 40 can realize the purpose of automatically stacking after the surface quality inspection of printed matter, it still has the following defects: first, the pin stopper in the pin stopper mechanism 42 The paper blocking effect is not good. The bottom printed matter 51 is easy to break away from the pin and fall under the friction of the conveyor belt of the delivery mechanism 41, resulting in inaccurate counting and disordered paper; 431 and the front and rear clapping plates 432, 433 and the belts of the lateral conveying belt mechanism 44 need to be separated by a certain gap, so for the first few printed matters stacked, it cannot be clapped together; the third, the lateral conveying belt Mechanism 44 has a long distance for conveying printed matter and a long time for paper output, resulting in low work efficiency
