Medium conveying device and medium conveying system

Abstract

The invention provides a medium conveying device and a medium conveying system, and relates to the automatic cash recycling system field. The medium conveying device comprises a scroll, a first drum, a second drum, a first conveyor belt, a second conveyor belt, and a driving motor. The two ends of the first conveyor belt are disposed on the scroll and the first drum respectively in a coiled manner, and the two ends of the second conveyor belt are disposed on the scroll and the second drum respectively in a coiled manner. The scroll is electromechanically connected with the driving motor, and the driving motor is used to drive the scroll to rotate along a clockwise direction or a counterclockwise direction, and is used to drive the first conveyor belt and the second conveyor belt to move along with the scroll. The width of the first conveyor belt is greater than a width of a preset medium. Compared with the prior art, the medium conveying device and the medium conveying system are advantageous in that the first conveyor belt having the width greater than the preset medium width is used to convey the preset medium, and the preset medium having cracks are prevented from exceeding the two sides of the first conveyor belt, and the curling or the tearing of the medium is prevented.

Description

technical field [0001] The invention relates to the field of automatic deposit and withdrawal machines, in particular to a medium conveying device and system. Background technique [0002] At present, the cash ATMs widely used in financial institutions such as banks and stock exchanges can make customers deposit cash such as banknotes and coins or pay customers in cash according to the transaction content with customers. [0003] Existing cash automatic teller machine, it can be provided with identification device by the banknote inlet and outlet that carries out banknote giving and receiving between customers, and through this authentication device, the banknote that puts into banknote outlet is authenticated. For the banknotes identified as genuine banknotes, they can be transported to the currency box for storing banknotes through the conveying device; while for the banknotes identified as counterfeit or abnormal banknotes, they will be returned to the banknote exit throu...

AI Technical Summary

Problems solved by technology

[0007] However, due to the low strength of paper materials, banknotes may be bent, worn or cracked due to folding during circulation in the market.

In the case of winding such banknotes, since only the middle part of the banknotes is subjected to the friction force of the conveyor belt, while the parts on both sides are in a suspended state, different areas of the banknote surface are subjected to uneven forces, and the bending and cracks of the banknotes usually It will appear on the edge of the banknote. If the curved or cracked part is just on both sides of the conveyor belt, the parts on both sides of the conveyor belt will sag due to gravity, making the parts on both sides of the banknote lower than the plane of the middle part. , which in turn causes the banknotes to be more severely curled or even torn during the process of winding them to the spool

[0008] In this case, the curled or torn part of the banknotes may not be normally wound onto the peripheral surface of the reel, but jammed near the conveyor belt and the reel, causing failure of the entire conveying structure
