Description

Technical Field

[0001] The present invention relates to the technical field of automatic vending machines, and in particular to a delivery device of an automatic vending machine. Background Art

[0002] At present, with the development of mobile commerce, vending machines, as a convenient and intuitive mobile commerce tool, have begun to spread and develop rapidly around the world. In China, vending machines will become a potential huge industry with very broad prospects.

[0003] The existing application of vending machines is usually in places with large flow of people but relatively simple demand, such as vending machines selling beverages or instant noodles at bus stations or train stations. Traditional vending machines let the goods fall through the movement of the shelves themselves, which has problems such as multiple motion structures, high cost, high probability of failure and high control difficulty. The improvement of traditional vending machines is to use a lifting rod to lift the goods to the pickup device and then transport them to the delivery box. In order to allow the lifting rod to lift the goods, a large space needs to be reserved to avoid the shelf from sagging due to gravity deformation and interfering with the lifting rod, which will waste the internal space of the vending machine. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a delivery device for a vending machine to accurately locate the location of goods, thereby reducing the waste of internal space.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] The delivery device of the vending machine includes a pickup device and a delivery box, wherein the pickup device includes a pickup moving mechanism, a telescopic lifting rod mechanism, a pickup box and a goods indicating mechanism;

[0007] The pickup moving mechanism is connected to the pickup box;

[0008] The telescopic lifting rod mechanism is arranged on the pickup port of the pickup box, and the extension direction of the telescopic lifting rod mechanism is consistent with the direction of the pickup port of the pickup box;

[0009] The cargo indicating mechanism is fixedly connected to one side of the cargo picking box, and the cargo indicating mechanism comprises a laser indicator, and the laser emission direction of the laser indicator is consistent with the extension direction of the telescopic lifting rod mechanism.

[0010] The beneficial effects of the present invention are as follows: the delivery device of the vending machine, the picking-up moving mechanism drives the picking-up device to move to the corresponding position of the goods, and the laser indicator emits laser in the extension direction of the telescopic lifting rod mechanism, that is, the direction of the goods. The laser will be reflected when it encounters the goods, thereby accurately locating the position of the goods; at this time, the telescopic lifting rod mechanism extends out of the delivery box and reaches the bottom of the goods, and the picking-up moving mechanism drives the telescopic lifting rod mechanism on the picking box to move upward, that is, picks up the goods, so that the goods fall into the picking box through the picking port, and then the picking-up moving mechanism drives the picking box containing the goods to move to the delivery box, completing the delivery; the position of the goods is determined by laser reflection, and the goods are picked up accurately from under the goods, which solves the problem caused by deformation of the shelf, thereby reducing the waste of internal space.

[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0021] Please refer to Figures 1 to 7 , a delivery device of a vending machine, including a pickup device and a delivery box, wherein the pickup device includes a pickup moving mechanism, a telescopic lifting rod mechanism, a pickup box and a cargo indicating mechanism;

[0022] The pickup moving mechanism is connected to the pickup box;

[0023] The telescopic lifting rod mechanism is arranged on the pickup port of the pickup box, and the extension direction of the telescopic lifting rod mechanism is consistent with the direction of the pickup port of the pickup box;

[0024] The cargo indicating mechanism is fixedly connected to one side of the cargo picking box, and the cargo indicating mechanism comprises a laser indicator, and the laser emission direction of the laser indicator is consistent with the extension direction of the telescopic lifting rod mechanism.

[0025] From the above description, it can be seen that the beneficial effects of the present invention are: the picking-up mobile mechanism drives the picking-up device to move to the corresponding position of the goods, and the laser indicator emits a laser in the extension direction of the telescopic lifting rod mechanism, that is, the direction of the goods. The laser will be reflected when it encounters the goods, thereby accurately locating the position of the goods; at this time, the telescopic lifting rod mechanism extends out of the shipping box and reaches the bottom of the goods, and the picking-up mobile mechanism drives the telescopic lifting rod mechanism on the picking box to move upward, that is, picks up the goods, so that the goods fall into the picking box through the picking port, and then the picking mobile mechanism drives the picking box containing the goods to move to the shipping box to complete the shipment; the position of the goods is determined by laser reflection, and the goods are picked up accurately from under the goods, which solves the problem caused by deformation of the shelf, thereby reducing the waste of internal space.

[0026] Furthermore, the position where the laser of the laser pointer is projected onto the goods on the vending machine and the position where the telescopic lifting rod mechanism is extended to the goods on the vending machine are on the same horizontal plane;

[0027] Alternatively, the height difference between the position where the laser pointer hits the goods on the vending machine and the position where the telescopic lifting rod mechanism extends to the goods on the vending machine is equal to the height difference between the bottom of the shelf of the vending machine and the bottom of the goods on the vending machine.

[0028] It should be noted that the laser of the laser pointer is used to determine the vertical position of the cargo.

[0029] From the above description, it can be seen that when the position where the laser of the laser pointer hits the goods on the vending machine and the position where the telescopic lifting rod mechanism extends to the goods on the vending machine are at the same horizontal plane, the laser of the laser pointer is emitted toward the goods until it leaves the goods, that is, it hits the lower edge of the goods, and then the telescopic lifting rod mechanism is considered to have reached a suitable vertical position. At this time, the telescopic lifting rod mechanism extends to the lower edge of the goods to lift them up; when the height difference between the position where the laser of the laser pointer hits the goods on the vending machine and the position where the telescopic lifting rod mechanism extends to the goods on the vending machine is equal to the height difference between the bottom position of the vending machine's shelf and the bottom position of the goods on the vending machine, the laser of the laser pointer is emitted toward the shelf until it leaves the shelf, that is, it hits the bottom position of the shelf, and then the telescopic lifting rod mechanism is considered to have reached a suitable vertical position. At this time, the telescopic lifting rod mechanism extends to the lower edge of the goods to lift them up.

[0030] Furthermore, the cargo indicating mechanism further comprises a scanner, and the scanning direction of the scanner is perpendicular to the laser emitting direction of the laser indicator.

[0031] From the above description, it can be seen that the scanner is used to scan the QR code information on the goods to obtain information such as whether the goods are expired, thereby solving the problem of blind shipment of traditional vending machines and ensuring the correctness of shipment of self-service vending machines.

[0032] Furthermore, the telescopic lifting rod mechanism includes a telescopic motor, a rack assembly and a telescopic plate;

[0033] The telescopic plate is located at the inner side of the bottom of the pickup box, and a first sliding member and a first fixing member are provided at the bottom of the telescopic plate;

[0034] A second sliding member is provided at the bottom of the pickup box, and the first sliding member is slidably connected to the second sliding member;

[0035] The telescopic motor and the rack assembly are both located on the outside of the bottom of the pickup box, the driving gear on the telescopic motor is meshed with the transmission gear on the rack assembly, and the rack assembly includes a second fixing member, which passes through the bottom of the pickup box and is fixedly connected to the first fixing member.

[0036] From the above description, it can be seen that a preferred embodiment of a telescopic lifting rod mechanism is provided to achieve the purpose of lifting the goods after reaching the bottom of the goods.

[0037] Furthermore, it also includes a longitudinal stopper provided on the shelf of the vending machine at a position close to the delivery box;

[0038] The picking device also includes a rotating bracket and a rotating central support rod arranged on the rotating bracket, the picking box is rotatably connected to the rotating central support rod, the picking box is provided with a rotating force-bearing support rod extending toward the longitudinal blocking portion, the rotating force-bearing support rod is arranged on the picking box at a position located on the side with greater weight among the two sides of the rotating central support rod and away from the rotating central support rod, and the picking port of the picking box is arranged on the picking box at a position located on the side with less weight among the two sides of the rotating central support rod;

[0039] The shipping box and the longitudinal stopper are respectively located on two sides of the rotating central support rod.

[0040] From the above description, it can be known that the pickup port of the pickup box is on the side with less weight. Therefore, in the absence of external force, it tilts toward the side with greater weight, so that the pickup port of the pickup box faces upward, and the goods are on the heavier side of the pickup box; since the delivery box and the longitudinal baffle are respectively located on both sides of the rotating central support rod, after the rotating force-bearing support rod located on the heavier side of the delivery box encounters the longitudinal baffle, it has an upward lifting effect on the heavier side of the delivery box, thereby causing the delivery box to start rotating until the pickup port of the pickup box changes from upward to downward, and under the action of gravity, the goods flow out of the pickup port to the delivery box.

[0041] Furthermore, it also includes a recovery box, which is located below the shipping box.

[0042] From the above description, it can be seen that expired goods are sent to the recycling box for recycling.

[0043] Please refer to Figures 1 to 7 , Embodiment 1 of the present invention is:

[0044] This embodiment is placed in a vending machine, including a vending machine that sells medicines.

[0045] The delivery device of the vending machine includes a pickup device and a delivery box 2, the pickup device includes a pickup mobile mechanism 1, a telescopic lifting rod mechanism 3, a pickup box 4 and a cargo indicating mechanism 5; the pickup mobile mechanism 1 is connected to the pickup box 4; the telescopic lifting rod mechanism 3 is arranged on the pickup port 41 of the pickup box 4 and the extension direction of the telescopic lifting rod mechanism 3 is consistent with the direction of the pickup port 41 of the pickup box 4; the cargo indicating mechanism 5 is fixedly connected to one side of the pickup box 4.

[0046] Among them, the extension and stretching in this application refer to stretching out of the pickup box 4, and telescoping refers to stretching out of the pickup box 4 or shrinking into the pickup box 4.

[0047] like Figure 4As shown, the cargo indicating mechanism 5 includes a laser pointer 51, and the laser emission direction of the laser pointer 51 is consistent with the extension direction of the telescopic lifting rod mechanism 3. It should be known that in order to lift the cargo 8, the telescopic lifting rod mechanism 3 must first extend under the cargo 8, and then control the telescopic lifting rod mechanism 3 to rise, so as to achieve the effect of lifting. Therefore, the extension direction of the telescopic lifting rod mechanism 3 is designed to be parallel to the inclination direction of the cargo 8 on the shelf 61, that is, parallel to the bottom of each cargo 8 storage space on the shelf 61. Therefore, the laser emission direction of the laser pointer 51 should be parallel to the bottom surface of the cargo 8.

[0048] In this embodiment, if Figure 4 As shown, the position where the laser pointer 51 is projected to the goods 8 on the vending machine and the position where the telescopic lifting rod mechanism 3 is extended to the goods 8 on the vending machine are in the same horizontal plane; in other equivalent embodiments, the height difference between the position where the laser pointer 51 is projected to the goods 8 on the vending machine and the position where the telescopic lifting rod mechanism 3 is extended to the goods 8 on the vending machine is equal to the height difference between the bottom position of the shelf 61 of the vending machine and the bottom position of the goods 8 on the vending machine. In this way, the position of the goods 8 can be determined quickly, and after the position of the goods 8 is obtained, there is no need to move more in the vertical direction, so that the goods 8 can be picked out quickly.

[0049] like Figure 5 As shown, the telescopic lifting rod mechanism 3 includes a telescopic motor 31, a rack assembly 32 and a telescopic plate 33; the telescopic plate 33 is located at the inner side of the bottom of the pickup box 4 and a first sliding member and a first fixing member are provided at the bottom of the telescopic plate 33; a second sliding member is provided at the bottom of the pickup box 4, and the first sliding member is slidably connected to the second sliding member; the telescopic motor 31 and the rack assembly 32 are both located at the outer side of the bottom of the pickup box 4, the driving gear on the telescopic motor 31 is meshed with the transmission gear on the rack assembly 32, and the rack assembly 32 includes a second fixing member, which passes through the bottom of the pickup box 4 and is fixedly connected to the first fixing member. In this embodiment, the first fixing member and the second fixing member are both studs, which are fastened by a screw passing through; the first sliding member is a strip-shaped through hole, and the second sliding member is a slide bar, which plays the role of sliding and limiting.

[0050] like Figure 6 and Figure 7As shown, this embodiment also includes a longitudinal stopper 42 arranged on the shelf 6 of the vending machine at a position close to the delivery box 2; the picking device also includes a rotating bracket 43 and a rotating center support rod 44 arranged on the rotating bracket 43, the delivery box 4 is rotatably connected to the rotating center support rod 44, and a rotating force support rod 45 extending toward the longitudinal stopper 42 is arranged on the delivery box 4. The rotating force support rod 45 is arranged on the delivery box 4 at a position on the side with greater weight on both sides of the rotating center support rod 44 and away from the rotating center support rod 44, and the delivery port 41 of the delivery box 4 is arranged on the side with less weight on both sides of the rotating center support rod 44 on the delivery box 2; the delivery box 2 and the longitudinal stopper 42 are respectively located on both sides of the rotating center support rod 44.

[0051] In combination with the above, the working principle of this embodiment is described as follows: when the user inputs the goods 8 to be purchased, the vending machine knows the location of the goods 8. Since the goods 8 are pressed on the shelf 61 and only cause vertical displacement, their horizontal position remains constant during use, that is, the picking-up moving mechanism 1 drives the picking-up device to accurately reach the horizontal position, and what needs to be considered is the actual vertical position of the goods 8 due to the deformation of the shelf 61. At this time, the laser pointer 51 starts to emit laser light, and the laser light is reflected after encountering the goods 8 to be received by the laser pointer 51 until the time interval between the received laser light and the previous laser light is greatly different, that is, the laser light has been shot to the lower edge of the goods 8, and after descending according to the preset height to reserve space for the telescopic plate 33 to extend, it reaches a position suitable for picking out the goods 8. At this time, the telescopic motor 31 controls the telescopic plate 33 to extend, and the goods 8 can be picked out. As for whether the pickup port 41 of the pickup box 4 reaches the horizontal position of the goods 8 first, the laser measures the lower edge of the adjacent goods 8, but when the same goods 8 are placed in the whole row and the deformation is basically the same, the judgment is still valid; or the pickup port 41 of the pickup box 4 reaches the position adjacent to the goods 8 first, the laser measures the lower edge of the goods 8 to be purchased, so it is necessary to shift the horizontal position after obtaining the position, both belong to an implementation method of the present embodiment.

[0052] Then, after the goods 8 are picked out, they fall into the pickup box 4 along the telescopic plate 33, and the pickup moving mechanism 1 drives the pickup device to move above the longitudinal stop 42, and then controls the pickup device to move from top to bottom. During the movement, after the rotating force support rod 45 contacts the longitudinal stop 42, the pickup box 4 rotates along the rotating central support rod 44 in the direction opposite to the initial tilted state, as shown in FIG. Figure 7 As shown, the pickup opening 41 of the pickup box 4 is facing upward in the initial tilted state, and according to Figure 7 The picking box 4 rotates counterclockwise, and the picking port 41 of the picking box 4 changes from upward to downward during the rotation, so that the goods 8 fall into the shipping box 2 to complete the shipment.

[0053] Please refer to Figures 1 to 7 , Embodiment 2 of the present invention is:

[0054] The delivery device of the vending machine, based on the above-mentioned embodiment 1, further comprises a recovery box 7 , and the goods indicating mechanism 5 further comprises a scanner 52 , and the scanning direction of the scanner 52 is perpendicular to the laser emitting direction of the laser indicator 51 .

[0055] Among them, Figure 1 It can be seen that the recovery box 7 is located below the delivery box 2, and a longitudinal baffle is also provided at the corresponding position of the recovery box 7. Therefore, referring to the method of the above embodiment 1, the goods 8 to be recovered in the pickup box 4 can be dropped into the recovery box 7.

[0056] To summarize, the delivery device of the vending machine provided by the present invention, the picking-up moving mechanism drives the picking-up device to move to the corresponding position of the goods, and the laser indicator emits laser in the extension direction of the telescopic lifting rod mechanism, that is, the direction of the goods. The laser will be reflected when it encounters the goods, thereby accurately locating the position of the goods; at this time, the telescopic lifting rod mechanism extends out of the delivery box and reaches the bottom of the goods, and the picking-up moving mechanism drives the telescopic lifting rod mechanism on the picking box to move upward, that is, pick up the goods, so that the goods fall into the picking box through the picking port, and then the picking-up moving mechanism drives the picking box containing the goods to move to the delivery box to complete the delivery; the position of the goods is determined by laser reflection, and the goods are picked up accurately from under the goods, which solves the problem caused by deformation of the shelf, thereby reducing the waste of internal space; in addition, the scanner is used to scan the QR code information on the goods to obtain information such as whether the goods are expired, and the expired goods are sent to the recycling box to realize recycling processing, thereby solving the problem of blind delivery of traditional vending machines and ensuring the correctness of delivery of self-service vending machines.
