Patent Name Patented Applicant Zhang Yan Primary Applicant for Used Cans and Beverage Bottles Patented Applicants Address 100083 Beijing Beijing Forestry University Basic School Electronic 01-1 Inventor Zhang Yan Application (Patent) No. 200510011737.4 Date of Application 2005.05.18 Certification Date Approval Announcement No. 1707528 Auditing Notice Day 2005.12.14 Manual CD No. D0550 Main Classification No. G07F7/06 Classification No. G07F7/06 Subdivision Original Application No. Priority Abstracts The present invention has used a can and a beverage bottle with a paid recovery device from a cabinet, a bottle and a can The inlet, the inlet pipeline, the separation screen pipeline, the waste pipeline and the storage box constitute a detection zone between the inlet pipeline and the separation screen pipeline, and is provided with a detection baffle, a diameter measurement probe and a split screen baffle, and the weight is set. Detection strain gauges, transparency detection light pair tubes, conductive detection electrical contacts, magnetic detection sensors, movable panels driven by a DC motor, microprocessors connected by digital gate switches to all detection points, extended by latches After the relay is driven by the corresponding motor and a strain gauge for preventing vandalism is used, it is a method with multiple detection methods. The automatic recovery device for beverage bottles and aluminium cans, together with the currency recovery mechanism, can automatically pay for different recyclables, at the same time it has certain prevention capabilities, is easy to promote, is easy to use, is conducive to environmental protection and benefits from good habits. Cultivation, with a very high promotional value. Sovereign items 1, used cans and beverage bottles paid recovery device, which is characterized in that a bottle inlet (7) is provided on a box (1), and a curved pipe (8) is arranged inside, and the lower line of the pipe is straight The zone is a detection zone (11). A detection baffle (10) is arranged below the detection zone (11). Above the detection baffle (10), two large-diameter measurement probes are set at an included angle ( 4,5), two small-diameter measurement probes (2, 3) are also set down slightly, and a number of strain gauges (Y1, Y2) are provided on the surface of the detection baffle (10). A plurality of pairs of needle-like electrical contacts (B20) and magnetic sensors (C12) are disposed on two adjacent detection zone walls of the diameter measurement probe plate, and at least one pair is relatively positioned outside the pin-shaped electrical contact points. Photoelectric pair tube (G21), the detection zone detection baffle (10) below the bifurcation is provided with a separation screen pipe (14) and a waste pipe (15), and a bifurcating screen baffle (16) is provided at the bifurcation port. The separate screen pipe (14) is connected to the recovery box, the detection baffle (10), the size and diameter measurement probe (2, 3, 4, 5) and the partition screen baffle (16) are made of a DC motor (M6, M2, M3, M4, M5, M7), these motors (M*) Each one is controlled by a microprocessor (U6) connected to two relays (JD*-1, JD*-2) via the two output pins of several 8-bit latches (U7, U8, U9, U10). Diameter measuring probes (2, 3, 4, 5) are provided with contact switches (K*-3) at the front end, said contact switches, strain gauges, needle-like electrical contacts, magnetic sensors and photoelectric counter tubes The outputs are connected to the input port of the microprocessor U6 via a number of digital strobe switches (U1, U2, U3, U4). The bottle inlet (7) is provided with an entrance flap (17), and the inner wall of the lower entrance is set on the inner wall. A door contact switch (KG31) and a motorized door latch (31) are opened, an output of said door switch (KG31) is connected to a pin of said digital strobe switch, and said door latch (31) motor ( M1) is connected to the two outputs of the eight-position latch through relays (JD1-1, JD1-2). A coin return mechanism (19) is also disposed in the front of the box (1). The operation of the device is performed. The process is as follows: (1) Open the entrance door, open the door contact switch and disconnect, the microprocessor senses that there is input; (2) close the entrance latch, make a delay, when the object falls on the detection baffle (3) Check if the weight of the object exceeds If it exceeds, skip to step (7). At the same time, check the magnetic property of the object to determine whether it is a tin. If it is a tin, skip to step (7). (4) Push two pairs of diameter measurement probes to detect the diameter of the object and judge the large bottle. Vials; (5) Detecting the transparency of objects to determine whether transparent beverage bottles; (6) Detecting the conductivity of objects, and judging whether they are metal products; (7) When judging from the above tests to a beverage bottle and aluminum can, the screening screen blocks Discard the pipe, open the detection baffle, let the bottle fall into the storage box; otherwise block the screening screen, open the detection baffle, discard the object; (8) According to the above judgment, the coin return device will pay the coin according to the predetermined price; (9) Detect the reset of the baffle, and at the same time, check whether the number of coins in the currency return mechanism meets the conditions. If the number of coins meets the conditions, open the entrance latch and wait for the next operation; if not, stop working.
