Goods discharging module of automatic vending machine

Abstract

The invention relates to a delivery module of an automatic vending machine, which includes a delivery channel with a delivery opening at the front end and a delivery opening at the upper middle, a delivery mechanism arranged in the machine body, and a motor fixed on the machine body to drive the delivery mechanism. The dialing mechanism is a four-bar mechanism. The four-bar mechanism is driven by the motor, and the cargo end at the upper end of the connecting rod forms a closed motion track that is divided into upper and lower parts by the cargo lane. Cargo opening, so that the cargo end moves under the cargo lane during the delivery stage, and then moves from the bottom of the cargo lane to the top of the cargo lane during the pushing phase and pushes the goods to the outlet. There is no need to set a push tongue, which simplifies the The structure of the entire push module saves manufacturing costs, facilitates installation, and reduces mechanical failure points. The installation is simplified and mechanical failure points are further reduced by setting the in-position detection device of the through-beam infrared detection and the remaining goods detection of the reflective infrared photoelectric detection at the import port.

Description

technical field [0001] The invention relates to an automatic vending machine, and more specifically, relates to a shipping module used on the automatic vending machine. Background technique [0002] The shipping module in the prior art includes a crank driven by a motor and a swing arm moved by the crank. Wherein, the upper end of the swing arm has a movable cargo-pushing tongue, and the cargo-pushing tongue reciprocates on the cargo lane at the upper end of the body, and the lower end of the swing arm is rotatably connected to the body below the cargo lane; one end of the crank is connected to On the rotating shaft of the motor, the other end of the pin shaft is connected to the middle part of the swing arm and is arranged in the chute. When the motor drives the crank to rotate, the crank stirs the swing arm to swing back and forth, and the goods-pushing tongue at the upper end of the swing arm repeatedly pulls and releases goods in the goods lane. In the structural princ...

Problems solved by technology

However, this kind of push tongue is easy to get stuck due to the failure of the spring during use, and the contact of the travel switch is easy to oxidize, has a short life, and is prone to poor contact.

When the limit switch of the remaining goods port fails, the machine will have two failures: in the case of goods, the detection result is that there are left goods or in the case of no goods, and when the in place limit switch fails, it is easy to cause a transaction, failure of two shipments
