Description

Bullet rail mounted screw rod transmission automatic delivery mechanism for commodity

Technical Field

The utility model relates to an automatic machine of selling goods and product promotion commercial machine field especially relate to the automatic cargo discharging mechanism of projectile rail mounted screw rod transmission of commodity.

Background

The prototype of vending machines was originally produced since 1925, and the types of products displayed and sold have been advanced from the first stamp cigarettes to food and beverages. With the rapid development of commodity economy, the variety of products is more and more, new products are continuously pushed out, and the packaging of the products is more and more personalized and is not just qualified. However, the internal goods loading and unloading mechanism of most of the vending machines still remains in the original spring clip loading design, and the biggest practical problem of the spring clip loading type goods channel mechanism is that: the space utilization rate of the sold commodity is low, and the space waste is large; the spring is limited by the outer diameter and the pitch of the spring, and can not be flexibly suitable for bearing and selling various commodities; the goods loading is relatively complicated, the goods loading of the whole layer of goods shelf needs to be drawn out, or the goods can be placed after the springs are selected in place, and then the type and the number of the goods loading need to be manually calculated; sometimes, a spring is jammed. Besides the spring goods channel type vending machine, the vending machine with the goods channel carried by the belt is also available on the world, and the problem of the vending machine is that: although the goods carrying and delivering device can meet the carrying and delivering requirements of a plurality of goods with different volume sizes and outer package sizes, the space utilization rate is the lowest, and one complete machine cannot accommodate more unit quantities of goods; the cost of a single cargo channel is high and the weight is heavy; the efficiency of goods delivery is also low. In addition to the two aforementioned existing channels, there are some vending machines dedicated to the sale of beverages or cigarettes, which have severe restrictions on the appearance of the food products and therefore cannot be used for the sale of other goods. In some patent documents, there is a design for mounting commodities in a spring form, which solves the problems of low space utilization rate, low commodity applicability and the like of the existing vending machine, but exposes a more prominent problem in the actual operation process: the goods-loading speed is seriously low. The actual measurement of the spring-loaded vending machine shows that 20 commodities are loaded on a single machine, the unit quantity is 1000 bags, 2 people are skillfully matched with the loading, the required average time is about 1 hour and 30 minutes, and the high operation cost is caused for an operation company due to the overhigh time and personnel cost. In order to solve many problems existing in the existing products and technologies, a new design and solution are needed.

The main function of the track seam is that the bullet neck freely passes through the track seam, and the bullet body cannot naturally penetrate through the track seam due to the fact that the outer size or the cross-sectional shape of the bullet body is larger than or limited by the shape and the size of the track seam, so that the bullet body can be carried on the bullet track by obtaining the natural supporting force of the bullet track. The body of the bullet is in a long strip shape in general, and the shape of the cross section shape can be hollow tube shape, long strip shape, sheet shape, barrel shape and spiral line shape, including but not limited to the above examples. The bullet body carries on the track seam department on the bullet rail, receives the influence of shape size and can't pass the track seam to can receive the holding power that the bullet rail provided, make the loading projectile body can carry the goods of certain weight and not drop.

The utility model discloses a principle is elucidated: the cargo carrying bullet is an intermediate part with the functions of bearing and connecting, the bullet body of the cargo carrying bullet is clamped above the rail seam, the bullet neck penetrates through the downward extending part of the rail seam and expands outwards to form a street hanging head, and the street hanging head is directly connected with commodities. Thus, the goods can be hung on the bullet rail through the cargo-carrying bullet body. The loaded projectile body can move along the track seam, so that goods can be loaded and unloaded. When goods are loaded, the goods with loaded projectiles are hung on the projectile rail through the projectile body and are sequentially pushed inwards along the rail gap direction. When goods are delivered, the power device operates to drive the transmission part to enable the propeller to push the goods-carrying projectiles on the projectile rail to the delivery end, and the power device stops when goods-carrying projectiles with the quantity sold pass through the detection range of the sensor, so that the delivery is completed.

The above technical solution of the utility model has the following beneficial technical effects that the utility model provides an automatic shipment mechanism can be nimble freely seamless access automatic intelligence shipment or the control system of the class machine of selling goods, such as control circuit or P L C etc. through the signal access control system with the inductor, can realize the accurate automatic count and the control when commodity shipment and the shipment completely.

The invention can be applied to a novel trial-use retail all-in-one machine. All automatic vending machines and the like known at present do not have the function of providing free trial use of commodities among them for consumers, and the commodities loaded among them are sold in large packages. In addition, the limitation of the loading and transmission structure of the existing goods channel causes that the types of goods sold in the machine are few, the quantity of single goods is limited, and the goods are all large-package goods, which brings much inconvenience and poor experience to the purchasing of consumers. This is the primary reason why consumer acceptance, with the exception of beverage machines, is low throughout the country for a wide variety of vending machines. New products are constantly being brought up, while traditional vending machines are selling well known goods and do not provide the function of free trial use. In order to facilitate the popularization and the sale of new products, various new products with small packages are continuously emerged in the future, and the new products are trial articles and sales articles. The biggest problem of the existing automatic goods selling machine is that the machine can not adapt to the bearing and selling of new small packages with various sizes, volumes and shapes, which is determined by the inherent goods path structure, and the bearing capacity of unit goods of the whole machine is not more than 700 parts at most. If the commodity discharging mechanism is used, the internal arrangement and bearing of highly dense commodities can be realized, the actual condition is estimated, and the bearing of the unit quantity of commodities of the complete machine with the same volume can reach 3000 parts at most, which can not be achieved by the prior art. Furthermore, it is more important that the design of the cargo channel is fully compatible with the appearance, volume and size of the carried goods, which is not possible by the prior art. Plus its outstanding convenience when shipped, namely: the goods loading mechanism has the advantages that parts in the goods channel do not need to be reset, the goods channel parts do not need to be replaced, the partition plate parts do not need to be adjusted, the goods channel or the goods shelf does not need to be drawn out, the number of loaded goods does not need to be counted manually, only one loaded goods projectile body connected with the goods needs to be pushed into the corresponding goods channel when the loaded goods are loaded, and the goods loading speed and the loading convenience degree are the fastest and most efficient in the existing known goods channel mechanism.
