In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

In a preferred embodiment of the present invention, a rotary drum storage and shipping mechanism for a vending machine is provided that is mountable in a housing of the vending machine and is primarily operative to cooperate with other vending machine components to ship user-specified items.

The structure of the components of the rotary drum type storage and delivery mechanism of the vending machine and the actuation relationship therebetween will be described in detail below.

As shown in fig. 1 and 2, the main components of the rotary drum type storage and delivery mechanism of the vending machine include a main shaft 1, a storage drum 2, a lifting mechanism 5, a pushing mechanism 6, and the like. The storage cylinder 2 is a cylindrical storage container having a cylindrical interior in which the items 7 to be sold can be stored in a vertically stacked manner. The cross section of the cylindrical inner cavity can be in a circular, rectangular, regular polygon and other forms, and is specifically determined according to the shape of the goods 7 to be sold, so that the goods 7 to be sold can be loaded in the cylindrical inner cavity, and the goods 7 to be sold can be ensured to move vertically and freely, but the cross section of the cylindrical inner cavity cannot be excessively larger than the overlooking outline of the goods 7 to be sold, so that the goods 7 to be sold cannot move in a large range in the horizontal direction as much as possible, and the stacking regularity of the goods 7 to be sold is ensured. The storage cylinder body 2 is provided with a goods inlet and a goods outlet of goods 7 to be sold on the shell, and the goods 7 to be sold can be replenished from the goods inlet and output to the outside from the goods outlet according to the selection of a user. The plurality of storage cylinders 2 are provided, one or more kinds of goods 7 to be sold can be put into each storage cylinder 2, and only one kind of goods 7 to be sold in a single storage cylinder 2 is possible in consideration of the efficiency of shipment. The storage cylinders 2 are circumferentially distributed along the circumferential side of the main shaft 1, all the storage cylinders 2 are uniformly distributed in the circumferential direction as much as possible, and the mutual distance and the central angle are kept the same as much as possible, so that accurate and automatic control can be realized subsequently.

In the present invention, for convenience of description, a path through which the cartridge 2 is shipped from inside the cartridge 2 is referred to as a shipment lane, and the form of the shipment lane may be various. For example, for an article 7 to be sold, such as a beverage, a bagged instant food, etc., which can be supplied to a user without any processing, the article taking opening of the vending machine or the falling object passage directly connected to the article taking opening of the vending machine can be used as the shipment passage; however, for the goods 7 to be sold, which can be supplied to the user without processing, such as boxed rice flour, noodles, instant noodles, self-heating rice, etc., the heating area thereof or the transport path directly connected to the heating area can be used as the shipment path. Generally speaking, a rotary drum type storage delivery mechanism of a vending machine only needs to be provided with a delivery channel.

In the rotary drum type storage and delivery mechanism of the vending machine, the butt joint of different goods 7 to be sold and corresponding delivery channels is realized by rotating the storage drum 2 around the main shaft 1. Each storage cylinder body 2 is connected with the main shaft 1 through the rotating connecting mechanism 3 for transmission, so that the storage cylinder bodies 2 can synchronously rotate around the main shaft 1 under the driving of the main shaft 1. The specific form of the rotary connecting mechanism 3 is not limited, any component capable of connecting the main shaft 1 and the storage cylinder bodies 2 can be used, and the main shaft 1 can be connected with all the storage cylinder bodies 2 through a single rotary connecting mechanism 3 and can also be connected with different storage cylinder bodies 2 through different rotary connecting mechanisms 3.

As shown in fig. 3, in the present embodiment, the rotating connection mechanism 3 is a turret-type connection mechanism, the connection mechanism is in the shape of a circular truncated cone, a through hole is formed in the center of the connecting mechanism and coaxially sleeved on the main shaft 1 to rotate synchronously, connectors corresponding to the storage cylinders 2 are arranged at intervals along the periphery of the circular truncated cone, and each storage cylinder 2 is installed on the side portion of the main shaft 1 in an attitude perpendicular to the axis through the connectors. In this embodiment, because the inside goods that is filled with certain weight of storage barrel 2 and storage barrel 2 self have a take the altitude, consequently in order to guarantee the fixed reliability who rotates the in-process, set up two and rotate coupling mechanism 3 altogether, two rotate coupling mechanism 3 intervals and arrange in the not co-altitude department of main shaft 1 to each storage barrel 2 all links to each other with two rotation coupling mechanism 3 are stable.

All storage cylinder bodies 2 are in the rotating process around main shaft 1, and storage cylinder bodies 2 can pass through the shipment channel of whole rotary drum type storage shipment mechanism one by one, and the shipment ports on the shell body in turn can be aligned one by one and communicated with the shipment channel. The spindle 1 may be driven by an external driving mechanism, and the specific driving mechanism is not limited, and may be generally implemented by a motor. Therefore, according to the type of the goods 7 to be sold selected by the user, the storage barrel body 2 stored with the corresponding type of the goods 7 to be sold can be stopped at the position of the goods outlet channel through rotation, the goods outlet is aligned with and communicated with the goods outlet channel, and the goods can be delivered through the lifting mechanism 5 and the pushing mechanism 6.

Referring to fig. 2, in the present embodiment, all of the cartridge bodies 2 form a circular rotation region during rotation. For the purpose of facilitating the delivery, the delivery channel is located at the edge position outside the rotation area of all the storage cylinders 2, and the delivery opening on the housing of each storage cylinder 2 is located at the bottom of the side wall on the side facing away from the main shaft 1. That is, each of the outlets is located at the outer periphery of the rotation region so as to be able to be docked with the discharge passage.

In the present invention, unlike the conventional showcase-type vending machine, the goods 7 to be sold are vertically stacked in such a manner that the vertical height space of the vending machine can be fully utilized, thereby placing as many goods 7 to be sold as possible. However, in this vertically stacked article placement format, the shipment of the articles 7 for sale cannot be controlled using conventional shipping mechanisms. Therefore, in the present invention, a delivery mechanism is specially designed for such vertically stacked article placement patterns, which utilizes the cooperation of the lifting mechanism 5 and the pushing mechanism 6 to effect the transfer of the articles 7 for sale from the storage cylinders 2 to the delivery passage.

As shown in fig. 3 and 4, the lifting mechanism 5 and the pushing mechanism 6 are both disposed at the position of the delivery passage, and each storage cylinder 2 passes through the starting position of the delivery passage one by one while being driven by the main shaft 1 to rotate. As shown in fig. 5, each of the storage cylinders 2 may be loaded with the corresponding goods 7 for sale, and during the rotation of the storage cylinder 2, when the outlet of the bottom of the storage cylinder 2 having the goods 7 for sale is aligned with the outlet passage, the rotation of the storage cylinder 2 may be stopped to perform the discharging operation. The main function of the lifting mechanism 5 is to be able to controllably extend into the cylindrical inner cavity of the storage cylinder 2 with the outlet aligned with the outlet passage, lift other goods 7 to be sold in the cylindrical inner cavity except for the bottommost goods 7 to be sold, and separate the other goods 7 to be sold from the bottommost goods 7 to be sold, so that the other goods 7 to be sold do not press on the bottommost goods 7 to be sold, and the bottommost goods 7 to be sold can be smoothly pushed horizontally. The function of the horizontal pushing mechanism 6 is to push the bottommost article 7 for sale out of the outlet opening and into the discharge channel, said article being detached from the other articles 7 for sale.

In general, the height of the outlet in the housing of the storage cylinder 2 is greater than the height of a single item 7 to be sold but less than the sum of the heights of two items 7 to be sold, so that only one item 7 to be sold can be pushed into the outlet channel at a time.

The specific form of the lifting mechanism 5 and the pushing mechanism 6 is not limited, and any technical solution capable of achieving the above functions may be adopted. It should be noted that the mounting positions and configurations of the lifting mechanism 5 and the pushing mechanism 6 should ensure that there is no interference with the storage cylinder 2 in the rotating state, and the storage cylinder 2 can be shipped without rotating in cooperation with the lifting mechanism 5 and the pushing mechanism 6.

In general, the lowermost item 7 to be sold among the vertically stacked items 7 to be sold is shipped first, and the newly replenished item 7 to be sold is located at the uppermost level. Therefore, when the bottommost article 7 for sale needs to be shipped, all the articles 7 for sale above the bottommost article 7 for sale need to be lifted synchronously. At this time, the lifting force of the lifting mechanism 5 may directly act on the one layer of the goods 7 to be sold above the bottommost goods 7 to be sold, that is, the lifting force directly acts on the second layer of the goods 7 to be sold from bottom to top, and the goods 7 to be sold above can be synchronously lifted by the second layer of the goods 7 to be sold from bottom to top. In order to guarantee that the vertical goods 7 of selling of piling up can be by stable promotion, hoist mechanism 5 should include at least two sets of flexible lifting unit, and two sets of flexible lifting unit can be respectively in the different position to the second floor goods 7 of selling of up from down promote in step, guarantee by the equilibrium of the goods 7 of selling of promoting. In order to ensure that the lifting mechanism 5 does not interfere with the storage cylinder 2 in the rotated state, it should be mounted outside the storage cylinder 2 so as to extend into the cylindrical interior when lifting is required. Therefore, a hollowed-out area matched with each group of telescopic lifting assemblies is arranged at the bottommost goods 7 to be sold on the shell of each storage cylinder body 2, so that the end part of each group of telescopic lifting assemblies can extend into the cylindrical inner cavity from the outside of the shell through the hollowed-out area, and then the second layer of goods to be sold 7 from bottom to top is lifted, so that the goods to be sold 7 are separated from the bottommost goods to be sold, and the subsequent operation of the horizontal pushing mechanism 6 is facilitated.

In this embodiment, and with reference to fig. 6, a specific implementation of a lifting mechanism 5 having two sets of telescopic lifting assemblies is provided. Two sets of flexible lifting units set up respectively in the inside and outside both sides of storage barrel 2 rotation path. Each group of telescopic lifting assemblies comprises a telescopic driving mechanism 501 and a hook 502 which are arranged on a support, and the support is vertically arranged to provide mounting sites for the telescopic driving mechanism 501 and the hook 502. The middle part of the hook 502 is hinged on the support and can rotate around the hinge point, and the installation position of the hook 502 should be close to the hollow area formed at the bottom of the storage cylinder 2. The telescopic driving mechanism 501 may be any device capable of outputting telescopic displacement, such as a pneumatic or electric telescopic rod. The displacement output end of the telescopic driving mechanism 501 is connected with one end of the hook 502, the telescopic driving mechanism 501 can drive the hook 502 to rotate around a hinge point in the telescopic process, a hook body at the other end extends into the cylindrical inner cavity from the outside of the shell through a hollow area in an inclined mode, upward lifting force is applied to goods 7 to be sold on the second layer from bottom to top, and therefore the rest goods 7 to be sold except the goods 7 to be sold on the bottom layer can be lifted. In the rotation state of the cartridge body 2, the retractable driving mechanism 501 may drive the hook 502 to be disengaged from the cartridge body 2, thereby preventing interference with the rotation of the cartridge body 2.

In addition, the horizontal pushing mechanism 6 is matched with the lifting mechanism 5, and when the lifting mechanism 5 lifts the other goods 7 to be sold except for the bottom-layer goods 7 to be sold, the bottom-layer goods 7 to be sold can be pushed by the horizontal pushing mechanism 6. In the present embodiment, referring to fig. 6, the horizontal pushing mechanism 6 includes a guide rail 601, a window pushing chain 602, and a drive gear 603. During rotation, the storage cylinders 2 enclose an inner ring region in the interior, in which the entire flat pushing mechanism 6 is arranged for pushing the bottom product 7 to be sold from the inside out into the discharge channel. The driving gear 603 may be driven by an external device such as a motor. The casement window chain 602 is a conventional chain that can be bent only on one side, but cannot be bent again after reaching a straight posture during the reverse bending process to the other side. The window pushing chain 602 is arranged in the guide rail 601 to form a sliding pair, and the driving gear 603 is in meshing transmission with the window pushing chain 602, so that the window pushing chain 602 can slide along the guide rail 601 under the driving of the driving gear 603, and when the horizontal pushing operation is not needed, the whole window pushing chain 602 can be curled and contracted in the guide rail 601, thereby saving the occupied space; when the horizontal pushing operation is needed, the end of the window pushing chain 602 can extend out of the guide rail 601 and into the cylindrical inner cavity of the storage cylinder 2, so as to push the bottommost goods 7 to be sold to slide out of the goods outlet and enter the goods outlet channel.

In this embodiment, since the shapes of the side walls of different articles 7 to be sold are different, for some articles 7 to be sold with smooth side walls, the sliding phenomenon is likely to occur only by pushing the end portion of the push window chain 602, so that a wrapping sleeve 604 matching with the shape of the article 7 to be sold may be connected to the end portion of the push window chain 602, and the form of the wrapping sleeve 604 is not limited, so that the side of the wrapping sleeve 604 contacting with the article 7 to be sold can be engaged with the article 7 to be sold. By arranging the wrapping sleeve 604, the wrapping sleeve 604 can wrap the outer part of the side wall of the goods to be sold 7 under the pushing of the window pushing chain 602, and further a uniform pushing force is applied to the goods to be sold. Of course, whether or not the package body 604 is provided may depend on the particular form of the item 7 to be sold.

In addition, in the rotary drum type storage and delivery mechanism of the vending machine, a bottom platform 4 can be arranged below all the storage drums 2, and the bottom platform 4 can provide a mounting platform for the lifting mechanism 5 and the pushing mechanism 6. Meanwhile, the bottom platform 4 can also receive sundries or goods 7 to be sold which are accidentally dropped in the area of the storage cylinder 2, and the influence on other components below is prevented. It should be noted, however, that the bottom platform 4 is not in direct contact with the items 7 to be sold within each cartridge 2. The bottom of every storage cylinder body 2 self has the layer board of bearing goods 7 of selling, and storage cylinder body 2 is in rotatory in-process goods 7 of selling and bottom platform 4 contactless, but is carried by the layer board, prevents that the goods 7 of selling from moving the friction in the rotation in-process.

The concrete material of the rotary drum type storage shipment mechanism of the vending machine is not limited, and generally steel is taken as a main material. In order to reduce the overall weight, the storage cylinder 2 may be further provided with more openings. When the rotary drum type storage and delivery mechanism of the vending machine is installed in the vending machine, the main shaft 1 of the rotary drum type storage and delivery mechanism should keep a vertical posture and rotate in a matching way through the bearing. A driving mechanism such as a motor can be arranged at the bottom of the main shaft 1 and is driven by a belt, a coupling or a gear. The whole vending machine wraps the outer shell, a corresponding user interaction interface can be provided on the outer shell of the vending machine, a user can designate required commodities, and the components are similar to the traditional vending machine and are not repeated.

The above-described embodiments are merely preferred embodiments of the present invention, which should not be construed as limiting the utility model. Various changes and modifications may be made by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present invention. Therefore, the technical scheme obtained by adopting the mode of equivalent replacement or equivalent transformation is within the protection scope of the utility model.
