Description

Technical Field

[0001] This utility model relates to the field of automatic vending machine technology, specifically to a transfer vehicle, a conveying mechanism, and an automatic food vending machine. Background Technology

[0002] Vending machines, also known as automated vending machines, are machines that automatically dispense goods based on the amount of money inserted. They are commonly used equipment in commercial automation. The types, structures, and functions of modern vending machines vary depending on the items they sell, and they mainly include vending machines for snacks, beverages, boxed meals, hamburgers, and blind boxes.

[0003] Vending machines for foods such as boxed meals and hamburgers are often equipped with a transfer cart with a translation drive mechanism, a receiving mechanism, and a pushing mechanism. The translation drive mechanism is used to drive the transfer cart to move horizontally, the receiving mechanism is used to move items into the transfer cart, and the pushing mechanism is used to move items out of the transfer cart. Among them, the pushing mechanism is generally driven by a motor to move the push plate forward, thereby pushing the items out of the transfer cart.

[0004] However, the pushers of existing transfer vehicles can usually only move inside the transfer vehicle, with a very limited range. They can only push items out of the transfer vehicle, but cannot push items a greater distance. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a transfer vehicle, a conveying mechanism and an automatic food vending machine. The push plate of the transfer vehicle can move to the space outside the transfer base, which can effectively push the items a longer distance.

[0006] This utility model provides a transfer vehicle, including a transfer base, and a translation drive mechanism, a receiving mechanism, and a pushing mechanism disposed on the transfer base. The pushing mechanism includes a linear drive mechanism disposed on the transfer base, a fixed guide rail fixedly disposed on the transfer base, a first slide block slidably disposed on the fixed guide rail, a movable guide rail fixedly disposed on the first slide block, a second slide block slidably disposed on the movable guide rail, and a push plate fixedly disposed on the second slide block. The movable guide rail is parallel to the fixed guide rail, and a pulley group is disposed on the movable guide rail. A closed-loop rope is wound on the pulley group. One side of the closed-loop rope is fixedly connected to the transfer base based on a rope bracket, and the other side of the closed-loop rope is fixedly connected to the second slide block.

[0007] The first slide block is driven by the linear drive mechanism to slide along the fixed guide rail. The movable guide rail is driven by the first slide block to extend or retract into the transfer base. The pulley group is driven by the movable guide rail to move. The second slide block is driven by the pulley group to slide along the movable guide rail based on the cooperation of the closed loop rope and the rope support. The push plate is driven by the second slide block to move out or into the transfer base.

[0008] Specifically, the linear drive mechanism includes a push-out motor fixedly mounted in the transfer base, a push-out screw rotatably mounted in the transfer base, and a movable nut fitted on the push-out screw. The output end of the push-out motor and the push-out screw are connected by a push-out gear set, and the movable nut is fixedly connected to the first slide block by a connecting block.

[0009] Specifically, the pulley assembly includes a first pulley and a second pulley. The first pulley is rotatably disposed at one end of the movable guide rail, and the second pulley is rotatably disposed at the other end of the movable guide rail. The axes of the first pulley and the second pulley are both perpendicular to the bottom surface of the transfer base.

[0010] The closed-loop rope is divided into a first rope section and a second rope section. The first rope section starts from the rope support, goes around the first pulley, and reaches the second slide block. The second rope section starts from the rope support, goes around the second pulley, and reaches the second slide block. The lengths of the first rope section and the second rope section are equal.

[0012] Specifically, the end of the push plate away from the second slide extends toward the receiving opening, and the end of the push plate away from the second slide is formed with a guide ramp, which is inclined in a direction away from the push-out opening.

[0013] Specifically, the receiving mechanism includes a receiving motor fixedly mounted in the transfer base, and a first roller and a second roller rotatably mounted in the transfer base. The first roller and the second roller are both parallel to the fixed guide rail. The first roller is located on the side away from the fixed guide rail, and the second roller is located on the side close to the fixed guide rail. A transfer belt is wound around the first roller and the second roller. The output end of the receiving motor and the first roller are connected by a receiving gear set for transmission.

[0014] Specifically, the transfer base is equipped with a photoelectric sensor for detecting the transfer of goods, and the working window of the photoelectric sensor points to the middle of the transfer belt.

[0015] Specifically, the translation drive mechanism includes an extension plate fixedly connected to the transfer base, a translation motor fixedly mounted on the extension plate, a translation drive gear fixedly mounted on the output end of the translation motor, and a translation transmission gear rotatably mounted on the extension plate, wherein the translation transmission gear and the translation drive gear mesh.

[0016] This utility model also provides a conveying mechanism, which includes a frame-shaped lifting frame, a lifting platform mounted on the frame-shaped lifting frame, and the transfer vehicle mounted on the lifting platform;

[0017] The frame-shaped lifting frame has guide plates on both sides, and each guide plate has a receiving space. A vertical guide rail, a first pulley, a second pulley, a vertical belt, and a lifting seat are arranged within the receiving space. The first pulley is located next to the top of the vertical guide rail, and the second pulley is located next to the bottom of the vertical guide rail. The vertical belt is mounted on the first pulley and the second pulley, and the vertical belt and the vertical guide rail are parallel to each other. The lifting seat is slidably connected to the vertical guide rail, and the lifting seat is fixedly connected to the vertical belt.

[0018] The bottom of the frame-shaped lifting frame is a support base plate, on which a lifting power shaft is rotatably mounted. The two ends of the lifting power shaft are respectively fixedly connected to the second pulleys on both sides of the frame-shaped lifting frame. A lifting drive motor is also fixedly mounted on the support base plate, and a lifting transmission gear is fixedly mounted on the lifting power shaft. The output end of the lifting drive motor meshes with the lifting transmission gear.

[0019] The lifting platform is fixedly connected to the lifting seats on both sides of the frame-shaped lifting frame; a horizontal guide rail and a horizontal toothed plate are fixedly installed in the lifting platform, the horizontal guide rail and the horizontal toothed plate are parallel to each other, and the horizontal guide rail and the vertical guide rail are perpendicular to each other; the transfer base of the transfer vehicle is slidably installed on the horizontal guide rail, and the output end of the translation drive mechanism of the transfer vehicle is engaged with the horizontal toothed plate.

[0020] This utility model also provides an automatic food vending machine, including a refrigerated cabinet and a heated cabinet. The refrigerated cabinet is equipped with the aforementioned conveying mechanism and a shelf. The heated cabinet is equipped with a heated dispensing mechanism, and the shelf conveys items to the heated dispensing mechanism based on the conveying mechanism.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The transfer vehicle of this utility model, through the coordinated action of fixed guide rail, movable guide rail, pulley block, closed-loop rope and rope support, decomposes the single input of the linear drive mechanism into the synthesis of the motion of the first slide and the relative motion of the second slide, thereby achieving a significant increase in the push plate stroke.

[0023] Specifically, when the linear drive mechanism drives the first slide to move along the fixed guide rail, the movable guide rail fixed on it extends or retracts accordingly; at the same time, the pulley block set on the movable guide rail is displaced due to the movement of the guide rail, and through the closed loop rope wrapped around the pulley block and fixed to the rope support on one side, the second slide is pulled to produce additional sliding along the movable guide rail.

[0024] This ingenious "mechanical follow-up amplification" mechanism ensures that the final displacement of the push plate (fixed on the second slide) is the superposition of the displacement of the first slide and the displacement of the second slide, resulting in nearly double the stroke. This allows the push plate to move to the space outside the transfer base, effectively pushing the items on the transfer vehicle a greater distance. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0040] Figure 1 This diagram shows a three-dimensional structural schematic of the transfer vehicle in an embodiment of the present invention. Figure 2 This diagram shows a first internal structure of the transfer vehicle in an embodiment of the present invention. Figure 3 This diagram shows a second internal structure of the transfer vehicle in an embodiment of the present invention. Figure 4A schematic diagram of the third internal structure of the transfer vehicle in an embodiment of this utility model is shown.

[0041] This utility model provides a transfer vehicle 10, which includes a transfer base 100, a translation drive mechanism 200, a receiving mechanism 300, and a pushing mechanism 400 disposed on the transfer base 100. The pushing mechanism 400 includes a linear drive mechanism 410 disposed on the transfer base 100, a fixed guide rail 420 fixedly disposed on the transfer base 100, a first slide block 430 slidably disposed on the fixed guide rail 420, and a movable guide rail 430 fixedly disposed on the first slide block 430. 40. A second slide block 450 slidably disposed on the movable guide rail 440 and a push plate 460 fixedly disposed on the second slide block 450. The movable guide rail 440 is parallel to the fixed guide rail 420. A pulley group 470 is disposed on the movable guide rail 440. A closed loop rope 480 is wound on the pulley group 470. One side of the closed loop rope 480 is fixedly connected to the transfer base 100 based on the rope bracket 490, and the other side of the closed loop rope 480 is fixedly connected to the second slide block 450.

[0042] The first slide block 430 is driven by the linear drive mechanism 410 to slide along the fixed guide rail 420. The movable guide rail 440 is driven by the first slide block 430 to extend or retract into the transfer base 100. The pulley block 470 is driven by the movable guide rail 440 to move. The second slide block 450 is driven by the pulley block 470 to slide along the movable guide rail 440 based on the cooperation of the closed loop rope 480 and the rope support 490. The push plate 460 is driven by the second slide block 450 to move out or into the transfer base 100.

[0043] The transfer vehicle 10 of this utility model, through the coordinated action of the fixed guide rail 420, the movable guide rail 440, the pulley block 470, the closed loop rope 480 and the rope support 490, decomposes the single input of the linear drive mechanism 410 into the synthesis of the motion of the first slide 430 and the relative motion of the second slide 450, thereby achieving a significant increase in the stroke of the push plate 460.

[0044] Specifically, when the linear drive mechanism 410 drives the first slide block 430 to move along the fixed guide rail 420, the movable guide rail 440 fixed thereon extends or retracts accordingly; at the same time, the pulley block 470 set on the movable guide rail 440 is displaced due to the movement of the guide rail, and the second slide block 450 is pulled along the movable guide rail 440 to produce additional sliding by the closed loop rope 480 wound around the pulley block 470 and fixed to the rope bracket 490 on one side.

[0045] This ingenious "mechanical follow-up amplification" mechanism ensures that the final displacement of the push plate 460 (fixed on the second slide 450) is the superposition of the displacement of the first slide 430 and the displacement of the second slide 450, resulting in nearly double the stroke. This allows the push plate 460 to move to the space outside the transfer base 100, effectively pushing the items on the transfer cart 10 a greater distance. Moreover, the pushing action of the push plate 460 is smooth and stable.

[0046] In some specific embodiments, please refer to Figure 2 , Figure 3 and Figure 4 The linear drive mechanism 410 includes a push-out motor 411 fixedly mounted in the transfer base 100, a push-out lead screw 412 rotatably mounted in the transfer base 100, and a movable nut 413 fitted onto the push-out lead screw 412. The output end of the push-out motor 411 and the push-out lead screw 412 are connected by a push-out gear set 414, and the movable nut 413 is fixedly connected to the first slide block 430 by a connecting block 415. The push-out motor 411 and the push-out lead screw 412 of the linear drive mechanism 410 can be distributed, making flexible use of the space within the transfer base 100, thereby helping to reduce the size of the transfer cart 10.

[0047] In some specific embodiments, please refer to Figure 3 The pulley assembly 470 includes a first pulley 471 and a second pulley 472. The first pulley 471 is rotatably disposed at one end of the movable guide rail 440, and the second pulley 472 is rotatably disposed at the other end of the movable guide rail 440. The axes of the first pulley 471 and the second pulley 472 are both perpendicular to the bottom surface of the transfer base 100. The closed-loop rope 480 is divided into a first rope section and a second rope section. The first rope section starts from the rope support 490, winds around the first pulley 471, and reaches the second slide block 450. The second rope section starts from the rope support 490, winds around the second pulley 472, and reaches the second slide block 450. The lengths of the first rope section and the second rope section are equal.

[0048] This arrangement of the pulley block 470 and the closed-loop rope 480 not only makes full use of the space below the movable guide rail 440, but also facilitates the connection of the closed-loop rope 480 to the rope bracket 490 and the second slide block 450, and also helps the second slide block 450 to obtain a large travel distance.

[0049] In some specific embodiments, please refer to Figure 1The transfer base 100 has a receiving opening 101 and a pushing opening 102 on its side, with the side containing the receiving opening 101 and the side containing the pushing opening 102 perpendicular to each other. The receiving mechanism 300 moves an item into the transfer base 100 through the receiving opening 101, and the pushing mechanism 400 moves an item out of the transfer base 100 through the pushing opening 102. The translation drive mechanism 200 is located on the side away from the receiving opening 101. This helps to avoid interference between the receiving mechanism 300, the pushing mechanism 400, and the translation drive mechanism 200.

[0050] For details, please refer to Figure 3 The push plate 460 extends from the end away from the second slide 450 toward the receiving opening 101. The end of the push plate 460 away from the second slide 450 is formed with a guide ramp 461. The guide ramp 461 is inclined in a direction away from the push-out opening 102 to facilitate guiding the item into the transfer vehicle 10.

[0051] In some specific embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The receiving mechanism 300 includes a receiving motor 310 fixedly mounted in the transfer base 100, and a first roller 320 and a second roller 330 rotatably mounted in the transfer base 100. Both the first roller 320 and the second roller 330 are parallel to the fixed guide rail 420. The first roller 320 is located on the side away from the fixed guide rail 420, and the second roller 330 is located on the side closer to the fixed guide rail 420. A transfer belt 340 is wound around the first roller 320 and the second roller 330. The output end of the receiving motor 310 and the first roller 320 are connected by a receiving gear set 350. The first roller 320 and the second roller 330 can support a relatively wide transfer belt 340, thereby facilitating the receiving of items.

[0052] For details, please refer to Figure 1 The transfer base 100 is equipped with an item transfer detection photoelectric eye 110. The working window of the item transfer detection photoelectric eye 110 points to the middle of the transfer belt 340 and is used to detect whether there is an item on the transfer belt 340 so as to control the operation of the receiving mechanism 300 and the pushing mechanism 400.

[0053] In some specific embodiments, please refer to Figure 3The translation drive mechanism 200 includes an extension plate 210 fixedly connected to the transfer base 100, a translation motor 220 fixedly mounted on the extension plate 210, a translation drive gear 230 fixedly mounted on the output end of the translation motor 220, and a translation transmission gear 240 rotatably mounted on the extension plate 210. The translation transmission gear 240 meshes with the translation drive gear 230. The translation motor 220 drives the translation drive gear 230 to rotate, which in turn drives the translation transmission gear 240 to rotate. The rotating translation transmission gear 240 meshes with a corresponding fixed toothed component, generating a reaction force. This reaction force can push the extension plate 210, thereby driving the transfer base 100 (transfer carriage 10) to move.

[0054] In some specific embodiments, the closed-loop rope 480 is a closed-loop steel wire rope, that is, a rope loop connected end to end of a steel wire rope, which is sturdy and durable.

[0055] In this utility model, the operation process of the transfer vehicle 10 receiving items is as follows: the output end of the receiving motor 310 rotates forward, driving the receiving gear set 350 to rotate, which in turn drives the first roller 320 to rotate; the rotating first roller 320 drives the transfer belt 340 and the second roller 330 to rotate; the rotating transfer belt 340 completely brings the items that have entered the receiving opening 101 into the transfer vehicle 10.

[0056] In this utility model, the operation process of the transfer cart 10 pushing out the item is as follows: the output end of the pushing motor 411 rotates forward, driving the pushing gear set 414 to rotate, which in turn drives the pushing screw 412 to rotate; the rotating pushing screw 412 drives the movable nut 413 to move linearly towards the pushing opening 102, and the linearly moving movable nut 413, based on the connecting block 415, drives the first slide block 430 to slide along the fixed guide rail 420 towards the pushing opening 102, and the sliding first slide block 430 drives the movable guide rail 440 to move towards the direction of extending out of the transfer base 100. The movable guide rail 440 drives the first pulley 471 and the second pulley 472 to move in the direction of extending out of the transfer base 100. The moving first pulley 471 and the second pulley 472 force the closed loop rope 480 to move as a whole in the direction of extending out of the transfer base 100 with the rope support 490 as the anchor point. The moving closed loop rope 480 pulls the second slide 450 to slide along the movable guide rail 440 in the direction of extending out of the transfer base 100. The sliding second slide 450 drives the push plate 460 to move out of the transfer base 100. Finally, the item is completely pushed out by the push plate 460 and away from the transfer vehicle 10.

[0057] Next, the output of the ejector motor 411 reverses, driving the ejector gear set 414 to rotate, which in turn drives the ejector screw 412 to rotate. The rotating ejector screw 412 drives the movable nut 413 to move linearly away from the ejector opening 102. The linearly moving movable nut 413, based on the connecting block 415, drives the first slide block 430 to slide along the fixed guide rail 420 away from the ejector opening 102. The sliding first slide block 430 drives the movable guide rail 440 to move towards the retractable transfer base 100. The moving movable guide rail 440 drives the first pulley 471 and the second pulley 472 to move towards the retractable transfer base 100. The first pulley 471 and the second pulley 472 move in the direction of 00, forcing the closed-loop rope 480 to move as a whole towards the retracted transfer base 100 with the rope support 490 as the anchor point. The moving closed-loop rope 480 pulls the second slide 450 to slide along the movable guide rail 440 towards the retracted transfer base 100. The sliding second slide 450 drives the push plate 460 to move into the transfer base 100. Finally, the movable guide rail 440 is completely retracted into the transfer base 100, and the push plate 460 is also completely moved into the transfer base 100, with the push plate 460 located above the side of the transfer belt 340 away from the push-out opening 102.

[0058] The transfer vehicle 10 of this utility model, through the coordinated action of the fixed guide rail 420, the movable guide rail 440, the pulley block 470, the closed-loop rope 480, and the rope support 490, decomposes the single input of the linear drive mechanism 410 into the synthesis of the movement of the first slide 430 and the relative movement of the second slide 450, thereby achieving a significant increase in the stroke of the push plate 460. Specifically, when the linear drive mechanism 410 drives the first slide 430 to move along the fixed guide rail 420, the movable guide rail 440 fixed thereon extends or retracts accordingly; at the same time, the pulley block 470 set on the movable guide rail 440 is displaced due to the movement of the guide rail, and through the closed-loop rope 480 wound around the pulley block 470 and fixed to the rope support 490 on one side, the second slide 450 is pulled to produce additional sliding along the movable guide rail 440. This ingenious "mechanical follow-up amplification" mechanism ensures that the final displacement of the push plate 460 (fixed on the second slide 450) is the superposition of the displacement of the first slide 430 and the displacement of the second slide 450, resulting in nearly double the stroke. This allows the push plate 460 to move to the space outside the transfer base 100, effectively pushing the items on the transfer cart 10 a greater distance. Moreover, the pushing action of the push plate 460 is smooth and stable.

[0059] In summary, the transfer vehicle 10 of this utility model achieves a smooth and stable push-out action with nearly double the stroke using a single drive source and a compact structure, completely overcoming the contradiction between stroke, stability and space occupation that is difficult to balance in traditional designs.
