An automatic vending machine that uses inclination gravity to assist in delivery

Abstract

The present invention provides an automatic vending device which utilizes inclination gravity to assist in delivery. The bottom of a refrigerator is made into an inclined surface, and the inclined surface is then divided into one or more channels in parallel along the inclined line. Different kinds of articles are placed in different channels respectively. By driving an adsorption mechanism through an X-axis and a Z-axis to only adsorb articles at the lowest point of each channel, the sale of all articles in the channel can be realized. Because the bottom of each channel is inclined, the articles will automatically move to the lowest point of their respective channels under the action of gravity. Therefore, a small area of ​​the refrigerator opening can be opened to facilitate the adsorption mechanism to enter and adsorb the articles at the lowest point, while most of the area is covered with an insulation door to avoid the loss of most of the cold inside the refrigerator. An air curtain system is arranged at the small open part of the refrigerator opening to again block a part of the cold and hot air exchange inside and outside the refrigerator.

Description

Technical Field

[0001] The present invention belongs to the field of automation technology of robot application and upgrading of traditional manufacturing technology, and specifically relates to an automatic vending machine that utilizes inclination gravity to assist in delivery. Background Art

[0002] At present, some of the automatic vending machines developed by people use the movement of a three-axis machine to open and close the freezer door and transport and sell the items. The transportation part is generally achieved by a traditional three-axis machine and an adsorption mechanism, and the door opening part is achieved by a traditional three-axis machine in combination with a door opening mechanism. With the increasing maturity of automatic vending devices, the market has higher and higher requirements for the degree of automation, stability, and optimization of equipment manufacturing costs of vending devices.

[0003] Traditional three-axis machine equipment consists of dual X-axis, Y-axis and Z-axis, which wastes mechanical space and requires the design of a door opening and closing mechanism. The equipment is bulky and complicated, and there is an urgent need to design a solution that simplifies the structure and reduces costs. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an automatic vending machine that uses inclination gravity to assist in delivery. The specific solution is as follows:

[0005] An automatic vending device utilizing inclination gravity to assist in delivery, comprising a refrigerator and a two-axis motion mechanism installed outside the refrigerator;

[0006] The refrigerator comprises a cabinet body and a cabinet door on the upper part of the cabinet body; the interior space of the cabinet body of the refrigerator body is provided with partitions parallel to the inclined line according to the volume of the items for sale, and the partitions divide the interior space of the cabinet body into a plurality of different material channels;

[0007] Goods are placed in the cabinet, and the bottom of the cabinet is set as an inclined surface with a certain inclination angle, so that the goods can move naturally to a lower place along the inclined surface under the action of gravity;

[0008] The two-axis motion mechanism includes a Z-axis bracket and an X-axis bracket. A suction cup is installed on the Z-axis bracket for extending into the interior of the cabinet to absorb corresponding commodities.

[0009] Furthermore, the two-axis motion mechanism includes a Z-axis bracket and an X-axis bracket; an X-axis slide rail is arranged on the X-axis bracket along the X-axis direction;

[0010] The Z-axis bracket is installed on the X-axis slide rail of the X-axis bracket and can move along the X-axis slide rail; the Z-axis bracket is installed with a Z-axis slide rail, and the Z-axis slide rail is provided with a slider that can move along the Z-axis slide rail, and the suction cup is installed on the slider.

[0011] Furthermore, the cabinet door reserves an open space corresponding to the lowest position of the material channel according to the volume of the items being sold, so that the suction cup can extend from the top into the interior of the freezer to absorb the corresponding goods.

[0012] Furthermore, an air curtain is provided in the open space to reduce the exchange of hot and cold air inside and outside the freezer, thereby reducing cold loss and frost.

[0013] The beneficial effects of the present invention are embodied in:

[0014] 1. The bottom of the freezer is set as an inclined surface with a certain inclination angle, so that the items placed in the freezer can automatically move to a lower position along the inclined surface under the action of gravity. The upper door of the freezer is left with an appropriate open space corresponding to the lowest point of the freezer, so that the items can be sucked into the freezer through the adsorption mechanism without opening the freezer door, so there is no need to set a door opening mechanism;

[0015] 2. Reduce the size of the door on the upper part of the freezer to reserve an open space at the lowest part of the material channel according to the volume of the items being sold, so that the suction mechanism can extend from the upper part into the freezer to suction the corresponding items being sold; this way, the door does not need to be opened when selling items, thus shortening the time required for a single sale;

[0016] 3. The conveying device of this vending machine only needs to consist of two-axis (X-axis, Z-axis) mechanisms and an adsorption mechanism, without the need for a three-axis mechanical mechanism and a door opening mechanism, thus saving mechanical space and production costs;

[0017] 4. An air curtain can be installed at the open part of the cabinet door at the top of the freezer as needed to avoid the exchange of hot and cold air inside and outside the freezer, and reduce cold loss and frost. BRIEF DESCRIPTION OF THE DRAWINGS
