Description

Technical Field

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

[0002] There are several types of existing vending machine aisles: the first type is that the aisles are set at an angle; the second type is that each aisle has its own power, such as spring-type aisles, conveyor belt aisles, and serpentine aisles that use gravity to fall; the third type is that a push plate is used at the back of the aisle and a robotic arm is used at the front to pick up goods.

[0003] In the first category, the inclined aisles reduce the entire shelf storage space by almost one-third, and the goods slide down automatically by gravity. The goods can only lie obliquely on the aisle with the maximum contact surface, and the space utilization rate is low; the second category of aisles with their own power have two disadvantages: first, the power device takes up space, resulting in a decrease in the utilization rate of the entire shelf; second, the cost is too high and the weight is heavy, which is not conducive to the construction and use of a large number of aisle shelves. For example, it is difficult to build more than 500 aisles; the third category of aisles requires a large enough space on the top of the aisle, and the robot takes the goods out of the upper space of the aisle, so the aisle occupies a large space, which reduces the loading rate of the shelf.

DETAILED DESCRIPTION

[0047] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figure 1-Figure 8 As shown, the present invention provides a drawer-type shipping device, including a cargo extraction mechanism, a cargo pushing mechanism and at least one shipping mechanism, wherein the shipping mechanism includes a cargo channel 100 with an opening on one side and a cargo bucket 200 disposed in the cargo channel 100 and capable of being moved out from the opening.

[0049] The cargo bucket 200 is provided with a cargo drop opening 300 for cargo to drop out, the cargo drop opening 300 is provided at one end of the cargo bucket 200 close to the opening, and the cargo pushing mechanism is used to make the cargo in the cargo bucket 200 drop out from the cargo drop opening 300; the cargo extraction mechanism is used to make the cargo bucket 200 extend from the opening in the cargo passage 100; the cargo drop opening 300 is provided at the bottom of the cargo bucket 200, and the cargo pushing mechanism is provided on the cargo extraction mechanism;

[0050] Or the cargo drop port 300 is arranged on the side wall of the cargo bucket 200, and the cargo pushing mechanism is arranged on the cargo discharging mechanism.

[0051] In some embodiments, the drawer-type delivery device may include a drawer mechanism and multiple delivery mechanisms. Generally, multiple delivery mechanisms are arranged side by side. The delivery channel 100 of the delivery mechanism has an opening, and the cargo bucket 200 can repeatedly enter and exit the delivery channel 100 through the opening.

[0052] When the cargo drop-off port 300 is arranged at the bottom of the cargo bucket 200, the cargo pushing mechanism is arranged on the cargo drawing mechanism; at this time, there is no support of the cargo aisle 100 below the cargo drop-off port 300, and the cargo in the cargo bucket 200 can fall from the cargo drop-off port 300; generally, the cargo drop-off port 300 can only allow one cargo to pass through; in order to allow the cargo to fall out of the cargo drop-off port 300, when the cargo drawing mechanism pulls the cargo bucket 200 out of the cargo aisle 100, the cargo pushing mechanism acts on the cargo to cause the cargo to fall from the cargo drop-off port 300.

[0053] When the cargo drop opening 300 is arranged on the side wall of the cargo bucket 200 , and the cargo pushing mechanism is arranged on the cargo delivery mechanism, the cargo pushing mechanism acts on the cargo to make the cargo fall from the cargo drop opening 300 .

[0054] Optionally, the cargo extraction mechanism includes a vacuum suction cup assembly that can be adsorbed on the cargo bucket 200 and a telescopic assembly that is connected to the vacuum suction cup assembly and enables the vacuum suction cup assembly to be telescopic;

[0055] The telescopic assembly can enable the vacuum suction cup assembly to absorb the cargo bucket 200 and then extend the cargo bucket 200 from the opening of the cargo passage 100 .

[0056] The vacuum suction cup assembly is connected to the vacuum system. When the extraction mechanism extracts the cargo bucket 200 from the cargo aisle 100, the vacuum suction cup assembly can be sucked onto the cargo bucket 200. Under the action of the telescopic assembly, the cargo bucket 200 is pulled out of the cargo aisle 100. When the cargo bucket 200 needs to be retracted into the cargo aisle 100, the telescopic assembly extends to return the cargo bucket 200 to the cargo aisle 100. At this time, the vacuum system stops vacuuming and allows air to enter the vacuum suction cup assembly, so that the vacuum suction cup assembly can be separated from the cargo bucket 200 when the telescopic assembly is retracted.

[0057] Optionally, the cargo bucket 200 has a ferromagnetic block 700 at one end thereof that can extend from the opening of the cargo aisle 100; the cargo extraction mechanism includes an electromagnetic component that can adsorb the ferromagnetic block 700 and a telescopic component that is connected to the electromagnetic component and enables the electromagnetic component to extend and retract; the telescopic component enables the cargo bucket 200 to extend from the opening of the cargo aisle 100 after the electromagnetic component contacts the ferromagnetic block 700.

[0058] When the cargo extraction mechanism needs to pull the cargo bucket 200 out of the cargo channel 100, the electromagnetic assembly and the ferromagnetic block 700 attract each other. Generally, the ferromagnetic block 700 can be iron. The electromagnetic assembly includes an electromagnet. After the electromagnet is energized, it attracts the ferromagnetic block 700 on the cargo bucket 200. The cargo extraction mechanism pulls the cargo bucket 200 out of the cargo channel 100. When the cargo drop-off port 300 of the cargo bucket 200 is pulled out of the cargo channel 100, the cargo extraction mechanism stops pulling the cargo bucket 200 out.

[0059] When the cargo drop port 300 is arranged at the bottom of the cargo bucket 200, the cargo pushing mechanism is arranged on the cargo drawing mechanism; at this time, there is no support of the cargo aisle 100 below the cargo drop port 300, and the cargo in the cargo bucket 200 can fall from the cargo drop port 300; generally, the cargo drop port 300 can only allow one cargo to pass through; in order to allow the cargo to fall out of the cargo drop port 300, when the telescopic component contracts, that is, when the cargo bucket 200 is pulled out of the cargo aisle 100, the cargo pushing mechanism acts on the cargo to make the cargo fall out of the cargo drop port 300.

[0060] After the cargo falls, the telescopic assembly begins to extend, causing the cargo bucket 200 to return to the cargo aisle 100; the electromagnet of the electromagnetic assembly is powered off, and the electromagnetic assembly no longer attracts the ferromagnetic block 700, and the telescopic assembly will not retract and pull the cargo bucket 200 out of the cargo aisle 100.

[0061] When the cargo drop opening 300 is arranged on the side wall of the cargo bucket 200 , and the cargo pushing mechanism is arranged on the cargo delivery mechanism, the cargo pushing mechanism acts on the cargo to make the cargo fall from the cargo drop opening 300 .

[0062] like Figure 2 and Figure 4 As shown, optionally, the cargo drop port 300 is arranged at the bottom of the cargo bucket 200, and the cargo pushing mechanism is arranged on the cargo extracting mechanism;

[0063] The cargo pushing mechanism is arranged on the telescopic assembly and moves along with the telescopic assembly; when the telescopic assembly retracts the electromagnetic assembly, the cargo pushing mechanism goes deep into the cargo bucket 200 to make the cargo fall from the cargo drop opening 300 .

[0064] Optionally, the cargo extraction mechanism further includes a housing 900, the telescopic assembly is disposed in the housing 900, and a limit rod 120 is disposed on the housing 900;

[0065] The pushing mechanism includes an elastic portion 112 and a push-down member 111 hinged to one end of the elastic portion 112 . One end of the elastic portion 112 is arranged on the telescopic assembly, and the other end is provided with the push-down member 111 . The elastic portion 112 is in contact with the limiting rod 120 .

[0066] The telescopic component is arranged in the shell 900 of the cargo-drawing mechanism. When the telescopic component is extended or retracted, the cargo-pushing mechanism follows the telescopic component to extend or retract. The elastic part 112 of the cargo-pushing mechanism is arranged on the telescopic component. When the telescopic component is extended or retracted, the height of the elastic part 112 is limited by the limiting rod 120. The elastic part 112 can be a spring sheet. As the telescopic component is continuously extended, the angle between the elastic part 112 and the telescopic component gradually becomes smaller, and the height of the push-down member 111 on the elastic part 112 gradually decreases; when the cargo-dropping hole of the cargo bucket 200 is extended from the cargo channel 100, the elastic part 112 is pressed to the lowest point by the limiting rod 120. At this time, the push-down member 111 extends into the cargo bucket 200 and acts on the cargo, causing the cargo to enter the cargo-dropping opening 300 and fall from the cargo-dropping opening 300.

[0067] Optionally, further, the telescopic assembly includes a driving motor 180, a driving screw 170 connected to the driving motor 180, and a telescopic sleeve 800 sleeved on the driving screw 170;

[0068] A limiting sleeve 190 is slidably disposed in the housing 900 . The limiting sleeve 190 is sleeved on the telescopic sleeve 800 . The limiting sleeve 190 enables the telescopic sleeve 800 to reciprocate linearly under the action of the driving screw 170 . The telescopic sleeve 800 is connected to the electromagnetic assembly.

[0069] The driving motor 180 is generally a servo motor, which is connected to the driving screw 170. When the driving screw 170 rotates, the telescopic sleeve 800 sleeved on the driving screw 170 is fixed by the limiting sleeve 190, so that the telescopic sleeve 800 cannot rotate. Such an arrangement enables the telescopic sleeve 800 to reciprocate along the axial direction of the driving screw 170 under the drive of the driving screw 170.

[0070] The electromagnetic component is arranged on the telescopic sleeve 800 , so that the electromagnetic component can perform linear reciprocating motion along the axis of the driving screw 170 , thereby realizing repeated pulling of the cargo bucket 200 .

[0071] like Figure 4 and Figure 5As shown, in order to enable the goods in the cargo bucket 200 to automatically move toward the cargo drop port 300, further, the cargo bucket 200 is provided with a pushing plate 400, a pushing assembly for moving the pushing plate 400 toward the cargo drop port 300, and a raised guide rail 130; the pushing plate 400 is provided with a groove 401 matching the guide rail 130; the guide rail 130 is a hollow structure, and a long hole 160 is provided on the guide rail 130; the pushing assembly includes a steering member 150 and an elastic member 140, the steering member 150 is provided at one end of the guide rail 130 close to the cargo drop port 300, one end of the elastic member 140 is connected to the inner wall of the cargo bucket 200 at the end away from the cargo drop port 300, and the other end bypasses the steering member 150 and is connected to the pushing plate 400.

[0072] The cargo pushing assembly enables the cargo pushing plate 400 to have a tendency to move toward the cargo drop opening 300 , so that after the cargo in the cargo bucket 200 falls from the cargo drop opening 300 , the cargo in the cargo bucket 200 will automatically move toward the cargo drop opening 300 .

[0073] Since the cargo can fall from the cargo drop port 300, in order to prevent the cargo from falling out of the cargo drop port 300 after moving above the cargo drop port 300, the cargo pushing assembly applies enough pressure to the cargo pushing plate 400 so that there is enough friction between the cargo and the inner wall of the cargo bucket 200, thereby preventing the cargo from falling from the cargo drop port.

[0074] A raised guide rail 130 is provided at the bottom of the cargo bucket 200 or on the side wall of the cargo bucket 200 . Generally, two guide rails 130 are provided at the bottom of the cargo bucket 200 , or one or more guide rails 130 are provided on the side walls of the cargo bucket 200 on both sides of the pushing plate 400 .

[0075] The guide rail 130 is a hollow structure, and there is a long hole 160 on the guide rail 130. The elastic member 140 can be an elastic rope. One end of the elastic member 140 passes through the long hole 160 on the guide rail 130 and is connected to the push plate 400, and the other end bypasses the steering member 150. The steering member 150 can be a cylinder or a rotating wheel, which changes the direction of the elastic member 140 so that it can be connected to the side wall of the cargo bucket 200 away from the cargo drop port 300, so that the cargo push plate 400 always has a tendency to move toward the cargo drop port 300.

[0076] like Figure 6 , Figure 7 and Figure 8 As shown, further, the cargo drop port 300 is arranged on the side wall of the cargo bucket 200, and the cargo pushing mechanism is arranged on the cargo delivery mechanism;

[0077] The cargo pushing mechanism includes a rear power assembly, a front cargo pushing assembly and a transmission member 600 for transmitting the rear power assembly to the front cargo pushing assembly; the rear power assembly includes a synchronization shaft 500 arranged on the cargo bucket 200, and power gears 501 are arranged at both ends of the synchronization shaft 500, the power gear 501 is meshed with a rack 101 arranged on the cargo channel 100, and a power wheel 502 is also arranged on the synchronization shaft 500; the front cargo pushing assembly includes a cargo pushing screw 220, a cargo pushing long board 210 arranged on the cargo pushing screw 220 and a driven wheel 230 for connecting with the power wheel 502 through the transmission member 600.

[0078] The cargo pushing screw 220 is arranged at the lower end of the cargo bucket 200, and a cargo pushing long groove is arranged in the cargo bucket 200 for limiting the movement trajectory of the cargo pushing long board 210; a hidden groove 201 is arranged in the cargo bucket 200 for hiding the cargo pushing long board 210, and the hidden groove 201 and the cargo drop port 300 are arranged in the cargo bucket 200 relative to each other.

[0079] When the cargo bucket 200 is pulled out of the cargo channel 100 by the cargo extraction mechanism, the power gear 501 is meshed with the rack 101, and the power gear 501 rotates with the movement of the cargo bucket 200, so that the power gear 501 drives the rotation of the synchronous extraction mechanism.

[0080] The power wheel 502 on the synchronous shaft 500 also rotates synchronously, and transmits power to the driven wheel 230 through the transmission member 600, which is generally a chain or a belt; the driven wheel 230 causes the cargo pushing screw 220 to rotate, but since the position of the cargo pushing screw 220 is fixed and the cargo pushing long plate 210 screwed on the cargo pushing screw 220 is restricted by the cargo pushing long groove, it cannot rotate and can only move along the cargo pushing long groove, so that the cargo in the cargo bucket 200 can be pushed out from the cargo drop port 300.

[0081] The long pushing board 210 is initially located in the hidden groove 201, so that the long pushing board 210 will not affect the pushing board 400 from pushing the goods to the front end of the cargo bucket 200. When the cargo bucket 200 begins to be pulled out, the long pushing board 210 moves out of the hidden groove 201, acts on the goods, and moves the goods toward the cargo drop port 300.

[0082] In order to ensure that the cargo extraction mechanism can correctly pull out the cargo bucket 200 of the designated cargo, further, an identification code is provided on the cargo bucket 200, and a code reader for reading the identification code is provided on the cargo extraction mechanism.

[0083] Generally, an identification code is provided on the ferromagnetic block 700 , and a code reader for reading the identification code is provided on the electromagnetic component.

[0084] There is an identification code on the ferromagnetic block 700, and the electromagnetic component reads the RFID corresponding to the cargo bucket 200 through the code reader, ensuring that the cargo extraction mechanism pulls the cargo bucket 200 containing the correct cargo bucket 200 out of the cargo aisle 100, wherein the ferromagnetic block 700 can be an iron block, the identification code can be an RFID code, and the code reader is an RFID code reader.

[0085] Optionally, the telescopic assembly includes a telescopic motor, a rack 101 and a telescopic long rod connected to the rack 101;

[0086] The telescopic motor is provided with a gear meshing with the rack 101, the telescopic rod is connected to the electromagnetic assembly, and the telescopic motor changes the rotation direction of the gear so that the rack 101 drives the telescopic rod to extend and retract;

[0087] A guide sleeve is slidably arranged in the housing 900 , and the guide sleeve is sleeved on the telescopic long rod.

[0088] The housing 900 is generally provided with a slideway, and the lower end of the guide sleeve is slidably arranged in the slideway, so that the guide sleeve can only move along the slideway.

[0089] In order to enable a cargo extraction mechanism to pick up cargo from multiple cargo buckets 200 , further, a moving mechanism is included, on which the cargo extraction mechanism is arranged, and the moving mechanism is used to move the cargo extraction mechanism to different cargo aisles 100 .

[0090] The moving mechanism generally includes at least a left-right moving mechanism or an up-down moving mechanism. Preferably, the left-right moving mechanism and the up-down moving mechanism are used in conjunction with each other, so that the moving mechanism has a larger moving range. The cargo extraction mechanism connected to the moving mechanism has a larger moving range, so that cargo can be extracted from cargo buckets 200 placed in multiple rows and columns. The structure of the moving mechanism is a conventional structure and will not be described here.

[0091] The present invention also provides an automatic vending machine, comprising the above-mentioned drawer-type delivery device.

[0092] The present invention also provides an automatic vending machine, which adopts the above-mentioned drawer-type delivery device and thus has all the beneficial effects of the drawer-type delivery device.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
