Abstract
The utility model discloses a foreign matter detection device, relating to the field of cash transactions. A feeding mechanism is used for placing fed banknotes. An ion blower is used for applying pressure to the banknotes inside the feeding mechanism trough pushing a baffle plate. A detection assembly is connected with the feeding mechanism and used for acquiring the weight and thickness of the banknotes in the feeding mechanism. A control unit is connected with the feeding mechanism, the detection assembly and the ion blower, and is used for controlling the feeding mechanism, the detection assembly and the ion blower. The control unit determines the presence of foreign matter according to the difference between the thickness detected by the detection unit and a predetermined reference signal. According to the utility model, the ion blower pushes the baffle plate to prevent the baffle plate from moving at the feeding mechanism and generating static electricity, thereby preventing influence to the detection of the thickness of banknotes; the detection assembly is used to acquire the thickness and weight of the banknotes, so that the accuracy of the detection of foreign matter is improved, especially for detection of metal foreign matter; and when the weight of the banknotes is compared with the reference signal, the difference is obvious, and the accuracy of detection is improved.
Description
Technical field
The utility model relates to money transaction field, relates in particular to a kind of detection device for foreign matter.
Background technology
At the discrepancy treating apparatus of bank note or deposit special machine etc., by user's deposit action, process in the device of bank note, in the situation that sneaked into mistakenly the foreign matters such as coin or safety pin in dropping into the deposit slot of deposit bank note, the foreign matter of having sneaked into enters into device context and easily occurs that bank note is stuck or the situation of mechanical disorder together with bank note.
Chinese patent (CN101123015A) discloses a kind of detection device for foreign matter, be illustrated in figure 1 detection device for foreign matter as the come in and go out schematic diagram of mechanism of a part of bank note in cash transaction device, bank note is come in and gone out mechanism by pick-up roller 22, the bank note discharge unit that conveying roller 23 and gate roller 24 form, by header board 25, pressing plate 26 and separation rail 27 and 28 bank note that form are pressed unit, by gear 29 with gather bank note that guide rail 30 forms and gather unit and detection is set and whether have the bank note that is put into bank note to have or not sensor 42, detect the separated front end of bank note and the separation sensor of end 43, the mechanism that opens and closes the gate 44 of bank note gateway forms.The antenna 37 of 3 Copper Foils is set on the surface of header board 25, for the protection of the cover 38 of this antenna.Antenna 37 is connected with the testing circuit 40 for detection of foreign matter through signal wire 39.Part or all of pressing plate 26 consists of conductor material, and its conductor part is through signal wire 41 ground connection.
If by using client bank note 1 to be put into the space in bank note gateway, closed shutter 44.Driving makes pressing plate 26 that the bank note 1 being put into is pressed to pick-up roller 22.Detecting unit detects the pressure to pick-up roller 22, if become predetermined value, pressing plate 26 stops.Judgement when then, control module 46 carries out whether having sneaked into the foreign matters such as coin 45 or safety pin in the testing circuit 40 by foreign matter detects the bank note 1 being put into is moved.
In the situation that not sneaking into foreign matter, due to the drive source driving of pick-up roller 22, conveying roller 23, so bank note is sent after separation one by one by gate roller 24.In the situation that sneaked into the foreign matters such as coin and safety pin in the bank note 1 being put into, to control module 46, transmit the signal that foreign matter is sneaked into, control module 46 occurs for returning to the control signal of pressing plate 26, and reverse drive motor, turns back to predetermined initial position pressing plate 26.Then, open the sluices 44 eliminating foreign matters.
This patent has realized when the foreign matters such as coin, safety pin are put into bill handling unit together with bank note, can detect the existence of foreign matter before starting to process bank note.But while there is non-metal foreign body in the bank note dropping into, can not detect, thereby cause machine to break down.
