Banknote leveling device

Abstract

The invention discloses a banknote leveling device, which comprises an array enhanced adsorption device (40) and a synchronous steaming and ironing leveling device (50) sequentially arranged in the moving direction of an air-permeable conveyor belt (10), the array enhanced adsorption device (40) ) close to the inside of the air-permeable conveyor belt (10) and rotate synchronously with the air-permeable conveyor belt (10), so that the banknotes are transported in a state of being separated from each other on the air-permeable conveyor belt (10); At the lower steam nozzle (52) on the negative pressure side of the air-permeable conveyor belt (10) and the upper steam nozzle (51) on the non-negative pressure side of the air-permeable conveyor belt (10), the synchronous banknote pressing device (54), the corner of the banknote or The local wrinkles are unfolded and leveled under the action of the high-temperature steam ejected from the upper and lower steam nozzles (51) (52), which can better adapt to the randomness of banknote folding corners or local wrinkles. It is fast and efficient, and is especially suitable for a large number of Automatic sorting of small notes.

Description

technical field [0001] The invention relates to a banknote leveling device, in particular to a banknote leveling device suitable for leveling a large number of banknotes. Background technique [0002] Bus companies in major and medium cities and commercial and retail enterprises generate a large number of change notes every day, especially the bus companies in large and medium cities have hundreds of thousands or even millions of change notes every day. Money collectors have to mechanically repeat the action of counting the change nearly ten thousand times every day. During holidays, the workload is even greater. Their working environment is dirty and tiring. "Counting the money until the hand cramps" is a true portrayal of them. , and inevitably commit occupational diseases. This problem that has plagued the public transportation and retail industries for a long time needs to be solved urgently. [0003] Some sorting equipment can realize dedusting, disinfection and ironi...

AI Technical Summary

Problems solved by technology

Although this kind of equipment can continuously transport banknotes so that banknotes can be processed in an orderly manner according to the process, it is very easy to overlap banknotes during the conveyor belt transportation, especially when processing a large number of banknotes, because a large number of banknotes are absorbed by the conveyor belt. As a result, the banknotes are partially absorbed, and the rest of the banknotes overlap each other, causing the banknotes to be stacked chaotically, which will affect the subsequent processing

Moreover, banknotes are usually not completely flat, and there may be folded corners and local wrinkles, which are obviously not conducive to subsequent processing, which is difficult to deal with in the prior art

[0004] The patent application "A Banknote Sorting Machine" (201610284901.7) proposes to use a movable suction nozzle to absorb and separate single banknotes, and then use elastic claws to unfold the curled and wrinkled banknotes. Obviously, simple mechanical elastic claws are difficult to adapt to. The complex situation of banknote wrinkling and the low efficiency of a single movable suction nozzle cannot meet the needs of a large number of banknote sorting; the patent application "A Banknote Sorting Equipment" (201610095441.3) proposes to use a negative pressure roller with dense adsorption holes on the surface to absorb zero banknotes Carry out separation, and then directly use the roller to flatten the wrinkled banknotes. Obviously, the roller adsorption of this scheme must have some interweaving between the banknotes, and the direct rolling of the rollers can only be effective for the banknotes with a small warping angle; "Coin sorting and packing machine" patent application (201610069708.1) proposes to use the negative pressure difference between the multi-stage negative pressure rollers to "tear" the banknotes adsorbed on the low negative pressure and transfer them to the surface of the high negative pressure roller step by step. For flat banknotes, obviously due to the small gap between the roller surfaces and the randomness of the banknote fold direction, it is difficult to achieve the effect of unfolding the banknotes during the transfer process; the patent application (201610214041.X) of "A Friction Type Banknote Flattening Device" was proposed Scrape the banknotes on the conveyor belt above the banknote conveyor belt to gradually spread the banknotes evenly on the conveyor belt, and then press the evenly distributed nail-like flexible teeth on the conveyor belt to flatten the banknotes on the conveyor belt, obviously wrinkled It is difficult for banknotes to pass over the hanging teeth and continue to be transported forward, and it is difficult for flexible small teeth to unfold banknotes with random folding directions; "Banknote Sorting Device" (201620032400.5) proposes to use a negative pressure perforated conveyor belt to transport banknotes, above the conveyor belt Set up a leveling assembly consisting of brushes, wheel brushes, rolling brushes, and air curtains. The banknotes "pass through the brushes in sequence to form a single layer, and the air curtains blow the banknotes. Turn the rolling brushes, wheel brushes, and counterclockwise Roller brush to flatten banknotes

", and then turn the banknotes over to the second perforated conveyor belt, "blow the banknotes through the air curtain in turn, turn the roller brush counterclockwise, the wheel brush and the roller brush clockwise" to flatten the reverse side to complete the finishing, relying on the function of the brush must have Some banknotes are still partially interlaced up and down on the perforated conveyor belt, and the goal of "painting into a single layer" is difficult to achieve. Secondly, the blowing of the air curtain only works on a small number of banknotes. Overlapping of adjacent banknotes

In a word, the prior art has not made substantial progress in the processing of a large number of banknotes (banknotes) folding corners and local wrinkles.
