Embodiment Construction
[0013] The present invention is divided into two parts, an infrared emitting circuit and an infrared receiving circuit, which are respectively arranged on both sides of the pick-up box of the commodity vending machine. One side of the pick-up box is provided with an infrared emitting circuit. There are N emission tubes, and the other side of the corresponding pick-up box is provided with an infrared receiving circuit, wherein there are also N detection circuits. In this embodiment, N=10 is used for description. Of course, N can also take other values, and the principle is the same . There are 10 infrared emission tubes from top to bottom on one side of the pick-up box. The light area emitted by each infrared emission tube is conical, and its conical brightness angle covers the entire space where the goods in the pick-up box fall.
[0014] see image 3 , In the infrared emission circuit, the anodes of the infrared emission tubes IR1-IR10 are connected to the 1 end of the conne...

A distribution sensing device of a commodity vending machine is used for judging whether the area of a commodity is detected to ensure accurate distribution of the commodity or to determine that the vending machine has faults. The distribution sensing device comprises a pickup box, one side of the pickup box is provided with an infrared transmission circuit, and the other side of the pickup box is provided with an infrared receiving circuit; the infrared receiving circuit comprises a sensing circuit, an amplifying circuit, a signal micro variable superposition processing circuit, an integral filtering circuit, a schmitt trigger circuit, a monostable circuit and a drive circuit; the sensing circuit is connected with the amplifying circuit, the amplifying circuit is connected with the signal micro variable superposition processing circuit; the signal micro variable superposition processing circuit is connected with the integral filtering circuit; the integral filtering circuit is connected with the schmitt trigger circuit; the schmitt trigger circuit is connected with the monostable circuit; the monostable circuit is connected with the drive circuit, and the drive circuit is connected with a master control panel of the commodity vending machine. The distribution sensing device has the advantage that the commodity can be ensured to reach the picture box accurately.
Description
technical field [0001] The invention relates to a delivery detection device of a commodity vending machine, which judges whether the commodity has been detected, so as to ensure the exact distribution of the commodity or determine that the delivery device has a fault. Background technique [0002] Traditional commodity vending machines, such as automatic vending machines, do not have detection devices. After the main controller of the commodity vending machine controls the distribution device to distribute the commodities, it assumes that the commodities have been delivered to the pick-up box by default. Due to some unpredictable factors, the distributed goods did not reach the pick-up box, such as the goods were caught by the delivery spring or the mechanical failure of the distribution device, etc., so that consumers could not get the goods they deserved after inserting coins, which easily caused consumer disputes . Contents of the invention [0003] The object of the p...
