Description

Lifting pick-up mechanism for vending machines

technical field

The invention relates to an automatic vending machine, in particular to an elevating delivery mechanism of the automatic vending machine, which is located at the front edge of the storage channel of the automatic vending machine, picks up and delivers selected commodities in a lifting manner, and then delivers the commodities to a designated shipping position.

Background technique

Most of the existing automatic vending machines drop the goods to the pick-up warehouse in a free-fall mode, and then the customer takes away the goods. This kind of free fall method is applicable to limited products, and can only sell low-end products that are not easily deformed, and they are shipped in the form of falling. It is not suitable for selling expensive and fragile products, and may affect customers' buying emotions. Although there are a few vending machines with lifting function on the market, the speed of picking up and delivering goods to the delivery location is slow, and the noise is loud, and there are often phenomena such as jamming, which affects customers' desire to buy.

In the above technical solution, the two sides of the synchronous lifting mechanism are symmetrically installed with guide rails and guide rail supports, sliders, slider link plates, lifting synchronous belts, and counterweights.

working principle:

The driving motor transmits power to the transmission shaft through the synchronous belt, and the transmission shaft realizes the lifting movement of the slider by lifting the synchronous belt. The receiving platform can be sent to the storage layer of the designated product by means of the lifting mechanism, the swing plate of the receiving platform is opened, and then the storage layer pushes out the product, and the swing plate is closed, so that the product can be reliably delivered to the receiving platform, and then by The lifting mechanism runs to the designated shipping position, and at the same time, the goods are sent to the shipping position under the push of the push plate, so as to realize the stable and reliable pick-up and delivery of the goods.

Advantages and effects:

The invention adopts synchronous belt transmission and conveying, and is controlled by a code disc, so that the positioning accuracy is high and the delivery speed is fast. Both ends of the cargo receiving platform are equipped with lifting synchronous belts, and the two ends can move synchronously after passing through the transmission shaft. The other side of the synchronous belt is equipped with counterweights to reduce vibration and noise, so that the cargo receiving platform can be raised and lowered more smoothly. The special design of the receiving platform, through the linkage mechanism, makes the swing plate move within a certain angle range, which can conveniently and reliably realize the delivery of goods from the storage layer to the receiving platform; even if the goods slip on the conveyor belt, they can also be moved Commodities are sent to the outlet under the action of the push plate, which not only effectively solves the unfavorable factors such as jammed goods, but also enables the commodities to be transported to the designated shipping position smoothly and reliably; the invention solves the problem that traditional vending machines are sold by dropping Commodity defects can sell valuable and fragile commodities, which improves the civilization and friendliness of the sales process.
