Description
Technical Field
[0001] The present invention relates to the technical field of intelligent vending machines, and in particular to an anti-theft intelligent vending machine. Background Art
[0002] A vending machine is a machine that can automatically pay for goods according to the coins inserted, or scan and pay according to the QR code on the display screen. Its sales are not easily restricted by time and place, can save manpower and facilitate transactions. It is a new form of commercial retail, also known as a 24-hour mini supermarket.
[0003] The existing automatic vending machines can deliver goods automatically, while some models of smart vending machines deliver goods by using their own internal motors to push the goods from the shelves. However, this delivery method makes it easy for goods at high places to be damaged when they fall, and some special goods, such as soda, will cause large vibrations when they fall, causing bloating inside the can, which is inconvenient. In addition, when such smart vending machines push out goods, some goods will be stuck between the shelf and the door frame glass, making it difficult for the goods to fall, which is inconvenient. In addition, the baffle used for taking out goods in general smart vending machines is generally connected to the shelf, and the structure of the take-out port is simple. It is easy for people to reach into the self-service vending machine from the outside to take out objects, and the anti-theft performance is poor. Summary of the invention
[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an anti-theft intelligent vending machine, which can protect the shielding mechanism and baffle exposed to the outside through a protective mechanism to prevent the baffle and the shielding mechanism from being damaged, and then start the shielding mechanism to drive the protective mechanism to unfold, so that the goods on the shelf can fall onto the containing mechanism and be driven by the driving mechanism to move to the bottom of the shielding mechanism, and then the goods fall to one side of the baffle, and the user can push open the baffle to obtain the goods, thereby reducing the problem of some goods falling and being damaged. After use, the shielding mechanism drives the protective mechanism to reset, so that the space between the bottom of the shelf and the baffle is blocked by the shielding mechanism, thereby improving the anti-theft performance of the vending machine.
[0005] The purpose of the present invention can be achieved by the following technical solutions:
[0006] An anti-theft intelligent vending machine comprises a vending machine body, and a shelf is installed inside the vending machine body, a door frame is fixedly connected to one side of the vending machine body, and a rectangular groove is opened at the bottom end of one side of the door frame, a baffle is rotatably connected inside the rectangular groove, a shielding mechanism is arranged on one side of the door frame, and a protective mechanism is arranged on the other side of the door frame, a driving mechanism is arranged between the door frame and the shelf, and a holding mechanism is arranged on the driving mechanism, the protective mechanism is driven to unfold by starting the shielding mechanism, and the baffle is connected with the shelf inside the vending machine body, so that the goods on the shelf can fall onto the holding mechanism and be driven by the driving mechanism until the goods move to the bottom end of the shielding mechanism, and then the goods fall to one side of the baffle, and the user can push open the baffle to obtain the goods, thereby reducing the problem of damage or soda bloating caused by some goods falling from a high place, and after use, the shielding mechanism drives the protective mechanism to reset, so that the space between the bottom of the shelf and the baffle is blocked by the shielding mechanism inside the vending machine body, thereby improving the anti-theft performance of the vending machine;
[0007] The shielding mechanism includes a transparent shell, and the transparent shell is slidably embedded in the door frame, and sliding holes are opened at four corners of one side of the transparent shell, and four sliding rods are fixedly connected to one side of the door frame, and the inner side walls of the four sliding holes are respectively slidably sleeved with the outer side walls of the four sliding rods, one side of the door frame is rotatably connected to an electric push rod, and the movable end of the electric push rod is rotatably connected to the top of the transparent shell, and one side of the door frame is located above the rectangular groove and is fixedly connected to a discharge frame. By starting the electric push rod, the electric push rod drives the transparent shell to slide on the four sliding rods. When the other side of the transparent shell is parallel to the door frame, the transparent shell is located before the shelf and the door frame, so that the transparent shell does not protrude from the door frame. At the same time, the transparent shell can rely on the bottom surface to close the discharge frame through which the goods pass, so that the space between the discharge frame and the baffle and the space where the shelf is located are closed inside the vending machine body. When in use, the electric push rod is started to drive the transparent shell to protrude from the door frame, so that there is enough space when the goods fall, so as to avoid some goods from being stuck when falling from the shelf. The transparent shell can be made of lighter and harder materials such as plastic.
[0008] The invention further lies in that: the protection mechanism includes a protection net frame, and one side of the protection net frame is fixedly connected to the other side of the transparent shell, the other side of the door frame is rotatably connected to two U-shaped net frames, and the adjacent sides of the two arms of the two U-shaped net frames are provided with guide grooves, the opposite sides of the protection net frame are respectively located between the two arms of the two U-shaped net frames, and the opposite sides of the protection net frame are slidably connected between the two adjacent guide grooves, when the transparent shell is pushed out by the electric push rod to protrude from the door frame, the protection net frame is driven by the transparent shell to move synchronously, so that the opposite sides of the protection net frame slide in the adjacent guide grooves respectively, thereby lifting the two U-shaped net frames to rotate away from each other, so that the transparent shell can protrude from the door frame, and when the transparent shell is reset, the protection net frame pulls the two U-shaped net frames to reset synchronously, so that the two U-shaped net frames and the protection net frame protect the transparent shell, and one side of the protection net frame and the U-shaped net frame are both mesh structures.
[0009] Furthermore, the other side of the door frame is provided with sliding grooves on both sides opposite to the rectangular groove, and a blocking net frame is arranged between the two sliding grooves, the two ends of the bottom surface of the blocking net frame are respectively slidably connected to the inside of the two sliding grooves, and the top of the blocking net frame is rotatably connected to the bottom surface of the protection net frame, so that when the transparent shell does not protrude from the door frame, the protection net frame drives the blocking net frame, so that the blocking net frame is attached to the baffle, so that the outside of the baffle is also protected, and when the transparent shell protrudes from the door frame, the protection net frame pulls the blocking net frame to be tilted and pulled up, so that the baffle exposes a gap, which is convenient for the user to push open the baffle with his hands to take out the goods.
[0010] Further, the driving mechanism includes two connecting frames, and the top ends of the two connecting frames are fixedly connected to the top surface of the vending machine body, both ends of the inner walls of the two connecting frames are rotatably connected with rotating rods, and the two connecting frames are provided with connecting grooves on opposite sides, a conveying belt is rotatably sleeved between the two rotating rods located in the same connecting frame, and the conveying belt on the same connecting frame is located inside two adjacent connecting grooves on opposite sides, a connecting plate is fixedly connected between the top ends of the two connecting frames, and a driving motor is fixedly connected to one side of the connecting plate, and two driving rollers are rotatably connected to the other side of the connecting plate, and one end of the two driving rollers is fixedly connected to a gear, the two gears are meshed, and the motor shaft of the driving motor passes through one side of the connecting plate and is connected to one The other end of each driving roller is fixedly connected, and one end of the rotating rods located at the top of the two connecting frames penetrates an inner wall of an adjacent connecting frame. One end of the outer wall of the rotating rods located at the top of the two connecting frames is rotatably sleeved between the outer walls of the adjacent driving rollers, and a transmission belt is connected. The containing mechanism is located between the two conveyor belts. By starting the driving motor, a driving roller is driven to rotate, and the meshing transmission between the two gears makes the direction of the other driving roller opposite to that of the one driving roller, so that the two driving rollers drive the two rotating rods to rotate synchronously and in opposite directions through the two transmission belts, so that the two rotating rods drive the adjacent conveyor belts to rotate synchronously and in opposite directions, so that the two conveyor belts drive the containing mechanism to move up and down, thereby transporting goods and reducing their falling distance.
[0011] The two cams are connected to each other via a rotation of the two connecting rods, and the two connecting rods are connected to each other via a rotation of the two connecting rods.
[0012] The U-shaped frame is provided with a plurality of movable grooves at both ends, and the two ends of the U-shaped frame are respectively fixedly connected to the adjacent sides of the two conveyor belts, and the two ends of the U-shaped frame are respectively provided with embedded grooves below the adjacent movable grooves. A slide plate is provided inside the U-shaped frame, and the two ends of one side of the slide plate are respectively slidably connected to the two movable grooves, and the other side of the slide plate is rotatably connected between the adjacent sides of the two conveyor belts. A supporting plate is provided inside the U-shaped frame, and the two ends of the supporting plate are respectively slidably embedded in the two embedded grooves, and a pull belt is fixedly connected between the other side of the slide plate and one side of the supporting plate. When the transparent shell protrudes from the door frame, the two conveyor belts are pulled out from the adjacent connection frame. At the same time, the two transmission belts will pull the slide plate to slide, so that the slide plate originally closed the U-shaped frame slides open and moves between the two transmission belts, and then due to the driving of the two insertion rods, when the U-shaped frame is driven to move by the two conveyor belts, the slide plate is The two transmission belts are driven to move synchronously, and the slide plate and the U-shaped frame are kept in a relatively parallel state. The U-shaped frame is moved to the bottom of the dropped goods by controlling the driving motor, so that the goods fall into the U-shaped frame or onto the slide plate. The distance between the rotating rods at both ends of the same conveyor belt is greater than the distance between the fixed rods at both ends of the same conveyor belt. When the U-shaped frame is driven by the conveyor belt to its bottom end close to the discharge frame, it is difficult to pass through the adjacent fixed rods due to the large rotating block. Under the pull of the U-shaped frame, the slide plate tilts, so that the goods that may fall on the slide plate fall into the U-shaped frame, and the slide plate pulls the pull belt to drive the sliding part of the carrier plate to open the carrier plate, so that the goods inside the U-shaped frame fall into the discharge frame, and then the user can push open the baffle to take the goods, and then the U-shaped frame moves to the space between the two transmission belts, and then the torsion springs on the two connecting blocks drive the two plug rods to reset, so that the two rotating blocks pull the adjacent transmission belt rotating parts to reset.
[0013] Furthermore, the top surface of the support plate is an inclined surface, so that the goods entering the U-shaped frame can slide through the inclined surface to the gap opened when the support plate slides, and then enter the discharge frame.
[0014] Furthermore, the inner side walls of the two conveyor belts are fixedly connected to a fixed plate, and a push plate is arranged under the two fixed plates. A plurality of rebound springs are fixedly connected between the bottom surfaces of the two fixed plates and the top surfaces of adjacent push plates. The two push plates are in contact with adjacent insertion rods. When the U-shaped frame pulls the slide plate to tilt, the two insertion rods will contact the two push plates to compress the adjacent rebound springs. Then, when the insertion rods are reset, the two push plates will press the two insertion rods to reset, and the rebound springs will further provide reset power for the insertion rods.
[0015] Furthermore, the discharging frame is rotatably connected with pallets on both sides relative to each other, and a torsion spring is provided at one end of each of the two pallets, one end of each of the two torsion springs is fixedly connected to one end of an adjacent pallet, and the other end is fixedly connected to a side wall of the adjacent discharging frame. When the transparent shell protrudes out of the door frame, the two pallets will be driven by the restoring elastic force of the torsion spring to slightly lift up one end away from each other, so that the two pallets are tilted, so that the goods falling out of the U-shaped frame can fall into the discharging frame through the two pallets.
[0016] Furthermore, one side of the support plate is an arc-shaped surface. When the two support plates are tilted, the opposite end parts of the two support plates will protrude to reset the transparent shell. The bottom surface of the transparent shell can press the middle position of one side of the two support plates to reset the two support plates. The arc-shaped surface on one side of the support plate makes it easier for the bottom surface of the transparent shell to press the two support plates to reset.
[0017] Beneficial effects of the present invention:
[0018] 1. By starting the shielding mechanism to drive the protective mechanism to unfold, and connecting the baffle with the shelf inside the vending machine body, the goods on the shelf can fall onto the containing mechanism and be driven by the driving mechanism until the goods move to the bottom of the shielding mechanism, and then the goods fall to one side of the baffle. The user can get the goods by pushing open the baffle, thereby reducing the problem of damage or soda bloating caused by some goods falling from a high place. After use, the shielding mechanism drives the protective mechanism to reset, so that the space between the bottom of the shelf and the baffle is blocked by the shielding mechanism inside the vending machine body, thereby improving the anti-theft performance of the vending machine. At the same time, the protective mechanism can protect the shielding mechanism and baffle exposed to the outside to prevent the baffle and shielding mechanism from being damaged;
[0019] 2. The transparent shell is controlled to slide on the slide bar by starting the electric push rod. When the transparent shell protrudes from the door frame, the discharging frame is connected with the shelf. When the other side of the transparent shell is parallel to the door frame, the discharging frame is closed by the bottom surface of the transparent shell. Moreover, when the transparent shell protrudes from the door frame, the transparent shell pushes the protective net frame to move, so that the protective net frame pulls the two U-shaped net frames to rotate and pulls the blocking net frame to move, so that the baffle is not blocked by the blocking net frame. After the transparent shell is reset, the transparent shell pulls the protective net frame to reset, so that the protective net frame and the two U-shaped net frames are reset to protect the transparent shell. At the same time, the protective net frame pushes the blocking net frame to reset, so that the blocking net frame closes the baffle, thereby improving the anti-theft performance.
[0020] 3. Start the driving motor to drive a driving roller to rotate, and use two gears to make one driving roller drive another driving roller to rotate synchronously and in opposite directions. Use two transmission belts to make the two top rotating rods on the two connecting frames turn in opposite directions, so that the two conveying belts rotate synchronously in opposite directions. The two conveying belts can be pulled by two insertion rods to move synchronously, so that the two transmission belts and the two conveying belts drive the containing mechanism to move synchronously, so as to adjust the position of the containing mechanism, so that the goods fall into the containing mechanism, and then move to the top of the discharge frame through the containing mechanism, so as to reduce the height of the goods falling, thereby reducing the impact and vibration of the goods;
[0021] 4. When the transparent shell protrudes from the door frame, the two transmission belts are pulled out of the adjacent connection frames, and then the U-shaped frame is driven to move by the two conveyor belts. At the same time, the two conveyor belts pull the two transmission belts to move synchronously through the insertion rods, so that the slide plate keeps moving synchronously with the U-shaped frame in parallel, and the U-shaped frame moves to the bottom of the dropped goods. Then the vending machine body starts, so that the goods fall into the U-shaped frame or the slide plate, and then the U-shaped frame moves to the bottom of the two conveyor belts, so that the U-shaped frame pulls the slide plate to tilt, so that the goods that may fall on the slide plate fall into the U-shaped frame, and the slide plate is synchronously pulled by the pull belt to slide the carrier plate, so that the goods fall into the discharge frame from the gap opened by the carrier plate.

Then, due to the driving of the two insertion rods 461, when the U-shaped frame 510 is driven to move by the two conveyor belts 442, the slide plate 530 is driven by the two transmission belts 451 is driven to move synchronously, and the slide plate 530 and the U-shaped frame 510 are kept relatively parallel, and the U-shaped frame 510 is moved to the bottom of the dropped goods by controlling the driving motor 430, so that the goods fall into the U-shaped frame 510 or onto the slide plate 530, and the distance between the rotating rods 440 at both ends of the same conveying belt 442 is greater than the distance between the fixed rods 450 at both ends of the same conveying belt 451. When the U-shaped frame 510 is driven by the conveying belt 442 to its bottom end close to the discharge frame 240, the rotating block 460 is too large to pass through the adjacent fixed rods 450, and the U-shaped frame 5 10 pulls the lower slide plate 530 to tilt, so that the goods that may fall on the slide plate 530 fall into the U-shaped frame 510, and the slide plate 530 pulls the drawstring 531 to drive the sliding part of the carrier plate 520 to open the carrier plate 520, so that the goods inside the U-shaped frame 510 fall into the discharge frame 240, and then the user can push open the baffle 130 to take the goods, and then the U-shaped frame 510 moves to the space between the two transmission belts 451, and then the torsion springs on the two connecting blocks 470 drive the two insertion rods 461 to reset, so that the two rotating blocks 460 pull the rotating parts of the adjacent transmission belts 451 to reset.
[0043] The top surface of the support plate 520 is an inclined surface, so that the goods entering the U-shaped frame 510 can slide through the inclined surface to the gap opened when the support plate 520 slides, and then enter the discharge frame 240.
[0044] The inner walls of the two conveyor belts 442 are fixedly connected to a fixed plate 480, and a push plate 482 is arranged under the two fixed plates 480. A plurality of rebound springs 481 are fixedly connected between the bottom surfaces of the two fixed plates 480 and the top surfaces of the adjacent push plates 482. The two push plates 482 are in contact with adjacent insertion rods 461. When the U-shaped frame 510 pulls the slide plate 530 to tilt, the two insertion rods 461 will contact the two push plates 482 to compress the adjacent rebound springs 481. Then, when the insertion rods 461 are reset, the two push plates 482 will press the two insertion rods 461 to reset, and the rebound springs 481 will further provide reset power for the insertion rods 461.
[0045] The discharging frame 240 is rotatably connected to the supporting plates 241 on both opposite sides, and a torsion spring is provided at one end of each of the two supporting plates 241, one end of each of the two torsion springs is fixedly connected to one end of the adjacent supporting plate 241, and the other end is fixedly connected to the side wall of the adjacent discharging frame 240. When the transparent shell 210 protrudes out of the door frame 120, the two supporting plates 241 will be driven by the restoring elastic force of the torsion spring to slightly lift up one end away from each other, so that the two supporting plates 241 are tilted, so that the goods falling out of the U-shaped frame 510 can fall into the discharging frame 240 through the two supporting plates 241.
[0046] One side of the support plate 241 is an arc-shaped surface. When the two support plates 241 are tilted, the opposite end parts of the two support plates 241 will protrude to reset the transparent shell 210. The bottom surface of the transparent shell 210 can press the middle position of one side of the two support plates 241 to reset the two support plates 241. One side of the support plate 241 is an arc-shaped surface, which makes it easy for the bottom surface of the transparent shell 210 to press the two support plates 241 to reset.
[0047] Working principle: When in use, the electric push rod 230 is started, so that the electric push rod 230 drives the transparent shell 210 to slide on the four slide bars 220. When the other side of the transparent shell 210 is parallel to the door frame 120, the transparent shell 210 is located between the shelf 110 and the door frame 120, so that the transparent shell 210 does not protrude from the door frame 120. At the same time, the transparent shell 210 can rely on the bottom surface to close the discharge frame 240 through which the goods pass, so that the space between the discharge frame 240 and the baffle 130 and the space where the shelf 110 is located are closed inside the vending machine body 100. When in use, the electric push rod 230 is started to drive the transparent shell 210 to protrude from the door frame 120, so that there is enough space for the goods to fall;
[0048] The electric push rod 230 is started to drive the transparent housing 210 to slide and protrude from the door frame 120, so that the transparent housing 210 pulls the two transmission belts 451 to move out of the adjacent connection frame 410, and the insertion rod 461 slides on the adjacent connection block 470. At the same time, the two transmission belts 451 pull the slide plate 530 to slide, so that the top surface of the U-shaped frame 510 is opened, and the transparent housing 210 pushes the protection net frame 310, so that the protection net frame 310 pulls the two U-shaped net frames 320 to rotate, and the protection net frame 310 pulls the blocking net frame 330 to be tilted and pulled up, so that the baffle 130 is exposed. At the same time, the two support plates 241 are slightly tilted due to the action of the adjacent torsion springs;
[0049] Then, the driving motor 430 is started to drive a driving roller 431 to rotate, so that one driving roller 431 drives another driving roller 431 to rotate synchronously through two gears 432, so that the two driving rollers 431 rotate synchronously and in opposite directions, and then the two driving rollers 431 drive the two rotating rods 440 to rotate synchronously and in opposite directions through two transmission belts 441, so that the two rotating rods 440 drive the adjacent conveying belts 442 to rotate synchronously and in opposite directions, so that the two conveying belts 442 drive the U-shaped frame 510 to move up and down. At the same time, the two conveying belts 442 pull the two transmission belts 451 to move synchronously through the two insertion rods 461, so that the two transmission belts 451 drive the slide plate 530 to keep parallel to the U-shaped frame 510 and move synchronously, and then the control The control driving motor 430 moves the U-shaped frame 510 to the bottom of the goods to be dropped, and then the internal mechanism of the vending machine body 100 is activated to push the goods from the shelf 110, causing them to drop onto the U-shaped frame 510 or the slide plate 530. Then, the two conveyor belts 442 drive the U-shaped frame 510 to move to the bottom of the two conveyor belts 442. Since the two rotating blocks 460 are too large to pass through the adjacent fixed rods 450, the U-shaped frame 510 pulls the slide plate 530 to tilt, causing the goods on the slide plate 530 to drop into the U-shaped frame 510. At the same time, the slide plate 530 pulls the drawstring 531 to pull part of the carrier plate 520, causing the goods to drop from the gap caused by the movement of the carrier plate 520 into the inside of the discharge frame 240. Then, the user can take out the goods by pushing the baffle 130.
[0050] After use, the two conveyor belts 442 drive the U-shaped frame 510 to move upward, so that the internal torsion springs of the two connecting blocks 470 drive the adjacent plug rods 461 to reset due to their own reset elastic force. At the same time, the two abutment plates 482 also press the two plug rods 461 to reset due to the reset elastic force of the adjacent rebound springs 481. Then the electric push rod 230 drives the transparent shell 210 to reset, so that the other side of the transparent shell 210 is parallel to the door frame 120, so that the transparent shell 210 presses the two support plates 241 to reset, and the transparent shell 2 10 closes the space between the discharge frame 240 and the shelf 110, and the transparent shell 210 drives the two transmission belts 451 to be partially embedded in the adjacent connection frame 410 and located in the adjacent conveyor belt 442. At the same time, the two transmission belts 451 drive the slide plate 530 to slide to close the top surface of the U-shaped frame 510. At the same time, the transparent shell 210 is reset to make the protective net frame 310 pull the two U-shaped net frames 320 to reset, and make the protective net frame 310 push the blocking net frame 330 to block the baffle 130.
