Technical Field

[0001] The invention relates to the technical field of vending equipment, and in particular to an intelligent towel vending machine that facilitates taking out towels. Background Art

[0002] Vending machines, also known as automatic vending machines, are machines that can automatically pay for goods according to the coins inserted. Vending machines are commonly used equipment for commercial automation. They are not 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. Common vending machines are divided into four types: beverage vending machines, food vending machines, comprehensive vending machines, and cosmetics vending machines. Among them, the products sold by comprehensive vending machines are mainly daily necessities.

[0003] Towels are a type of daily cleaning product that is consumed in huge quantities. However, due to the soft nature of towels and their packaging, towels are not commonly found in vending machines, especially in vending machines with relatively large storage capacities. Summary of the invention

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a smart towel vending machine that is convenient for towel retrieval, comprising a cabinet, an industrial computer is arranged in the middle of the front of the cabinet, a picking slot is arranged in the lower front of the cabinet, a spiral storage device is arranged in the upper inner part of the cabinet, a posture adjustment device is arranged in the lower part of the spiral storage device, the posture adjustment device is arranged in the middle of the inner part of the cabinet, a multi-state screening device is arranged in the lower part of the posture adjustment device, and the multi-state screening device is arranged in the lower inner part of the cabinet. When the smart towel vending machine that is convenient for towel retrieval is used, consumers use payment methods such as mobile payment to enable the industrial computer to drive the spiral storage device and the posture adjustment device to adjust the posture and take out the towels, and the multi-state screening device performs the delivery of towels when the towels are taken out normally and the collection of towels when the towels are taken out abnormally.

[0008] Preferably, the spiral storage device comprises a spiral box, a spiral square spring is arranged at the upper inner part of the spiral box, and a terminal rectangular tube is arranged at the lower opening of the spiral box, a flexible push block is slidably connected to the inner part of the terminal rectangular tube, and the higher straight side of the flexible push block is fixedly connected to the lower end of the spiral square spring. The sheet-packed towels are stored in the spiral box in a close parallel arrangement. The spiral towel storage method of the spiral box allows the use of very long springs, and allows gravity and friction to participate in the transportation process of the towels during transportation. All of these make it possible that no matter how many towels are left, the storage and transportation pressure will not change greatly, and the towels will not be damaged while achieving the transportation function. The spiral square spring with rounded corners can ensure uniform pushing force on the towels and avoid jamming. A longer slow-rebound material block is arranged at the front of the flexible push block, which can avoid damaging a part of the towels at the storage end while performing the pushing function. The curved plate structure of the lower half of the Z-shaped action plate is provided with friction patterns, which is conducive to reducing the pressure during storage and reducing To reduce the damage of towels, an upper opening is arranged on the upper part of the open end of the terminal straight square tube, a lower opening is arranged on the lower part of the open end of the terminal straight square tube, a Z-shaped action plate is arranged outwardly at the open end of the terminal straight square tube, and a side of the Z-shaped action plate away from the open end of the terminal straight square tube is rotatably connected to a servo motor through a rocker arm structure. When the industrial computer confirms the transaction, the spiral storage device starts to work, and the servo motor drives the Z-shaped action plate to rotate downward, and the middle horizontal plate of the Z-shaped action plate pushes a packaged towel to move downward. At this time, the total width of the lower opening can allow the packaged towel to leave the terminal straight box downward, and the curved plate structure of the upper part of the Z-shaped action plate prevents the outflow of the remaining towels. When the Z-shaped action plate is retracted upward, the middle horizontal plate structure of the Z-shaped action plate is withdrawn upward, and the extra space can adjust the contact state between the next packaged towel and the lower part of the Z-shaped action plate to prevent jamming.

[0009] Preferably, the posture adjustment device includes two counter-rotating combined roller devices, each of the combined roller devices includes an adjusting wheel shaft, and large gears are fixedly connected to both ends of the cylindrical surface of the adjusting wheel shaft, and a rectangular deep groove is provided on the inner side of each large gear near the gear teeth, and each of the rectangular deep grooves is arranged in a circular array. A nonlinear spring is arranged inside each of the rectangular deep grooves, and one end of each nonlinear spring is fixedly connected to the bottom surface of the corresponding rectangular deep groove near the center direction of the large gear. A rigid rod is arranged between the rectangular deep grooves opposite to each other of the two large gears, and each end of each rigid rod is fixedly connected to an end of the corresponding nonlinear spring away from the center direction of the large gear. When the packaged towel falls between the two counter-rotating combined roller devices, the elastic ring arranged at the elastic ring groove unit on the outer side of the rigid rod grasps and counter-rotates and squeezes the packaged towel for transportation. At this time, if the packaged towel is tilted, the corner at the bottom first squeezes the rigid rod, so that the nonlinear spring in the rectangular deep groove closer to the corner is squeezed, and the nonlinear spring can provide a certain range of screening tolerance.

[0010] Preferably, an elastic ring groove unit is provided at a position of each rigid rod cylindrical surface away from the adjusting wheel shaft, and each of the elastic ring groove units located on the same circumference constitutes an elastic ring groove structure, and an elastic ring is clamped inside each of the elastic ring groove structures. The rotation linear speed of the elastic ring here is reduced, and the wrapped towel falls down first at one corner and is subjected to extrusion damping, thereby slowing down. Since it can slip with the elastic ring to a certain extent, the relative falling speed of the other corner of the wrapped towel increases, and the wrapped towel is subjected to a greater posture adjustment. When its posture is corrected, the total friction between it and the elastic rings increases, and the slipping stops. At this time, the packaged towel is squeezed downward and transported, and the large gear belts on the same side of the two combined roller devices are connected with the belt-edge synchronous belt, and an adjustment brush is arranged in the middle above the two combined roller devices, and arc-shaped brush plates are arranged on both sides of the adjustment brush, and the inner side wall of each arc-shaped brush plate is arranged with a curved brush strip. When the packaged towel is pushed downward to the posture adjustment device by the Z-shaped action plate, the arc-shaped brush plate and the curved brush strip arranged by the adjustment brush constitute a uniform resistance in the horizontal direction, so that the packaged towel is decelerated and subjected to a certain posture adjustment, and a brushless motor is arranged at one end of the adjustment wheel shaft of the right combined roller device.

[0011] Preferably, the multi-state screening device includes a support beam, a long groove is opened in the middle of the support beam, a multifunctional sliding part is slidably connected to the outer side of the middle part of the support beam, the base of the multifunctional sliding part is provided with a slider body, a sliding groove is opened horizontally on the left side of the slider body, a bearing groove ring is fixedly connected to the right side of the slider body, and a rounded trapezoidal block is fixedly connected to the lower surface of the slider body, the multifunctional sliding part is arranged corresponding to the long groove, and the multifunctional sliding part can divide the three working states into two execution results.

[0012] Preferably, the inner left end of the long groove is fixedly connected with a transverse spring, and the right end of the transverse spring is fixedly connected to the outer cylindrical surface of the bearing groove ring, and a double pulley slide rod device is arranged below the multifunctional sliding member, and a ramp slide bar is arranged below the double pulley slide rod device, and an arrow-shaped guide device is arranged on the right of the ramp slide bar. If the total thickness of the towels transported by the posture adjustment device is abnormal, it means that a single towel has a larger specification abnormality, or the number of towels pushed is abnormal. At this time, the adjustment wheel axle of the combined roller device that can move laterally on the left is excessively squeezed to the left, and after the adjacent large gears lose engagement, the deformed belt along the synchronous belt can ensure that the adjacent large gears continue to rotate in opposite directions. Regardless of whether the extrusion displacement is insufficient or excessive, the rounded trapezoidal block of the multifunctional sliding member will not or will stop squeezing the double pulley slide rod device. At this time, the ramp slide bar will not hit the arrow-shaped guide device, and the goods will not be sent out, but fall into the collection box arranged at the lower right part of the vending machine.

[0013] Preferably, a guide plate base is provided at the bottom of the arrow-shaped guide device, guide plates are provided on both sides of the upper part of the arrow-shaped guide device, and magnetic buffer strips are provided at the side edges of each guide plate, and a delay spring is provided between the inner lower end of the guide plate on the right side and the guide plate base, and the metal spring of the delay spring is coated with a slow rebound coating layer, and an anti-stuck roller is provided at the uppermost part of the arrow-shaped guide device, and a concave slope plate is provided at the lower left side of the arrow-shaped guide device. If the total thickness of the towels transported by the posture adjustment device is normal, the ramp slide bar hits the arrow-shaped guide device, and the collision can transfer a smaller stroke to the light-load component, thereby generating an amplified stroke. The magnetic buffer strips provided on both sides of the arrow-shaped guide device can greatly extend the service life of the impact part. At this time, the guide plate deflects to the right, and the goods are sent to the picking slot through the concave slope plate. The slow rebound coating layer coated with the metal spring of the delay spring can produce a certain delay, thereby reducing the difficulty of accurate screening, and the anti-stuck roller can prevent the goods from getting stuck and reduce the impact damage to the goods.

[0014] (III) Beneficial effects

[0015] The present invention provides an intelligent towel vending machine that facilitates taking out towels. It has the following beneficial effects:

[0016] (1) The present invention is provided with three multifunctional devices that cooperate with each other. When the intelligent towel vending machine that facilitates towel retrieval is used, consumers use payment methods such as mobile payment to enable the industrial computer to drive the spiral storage device and the posture adjustment device to adjust the posture and take out the towels, and the multi-state screening device to deliver the towels when they are taken out normally and collect the towels when they are taken out abnormally.

[0017] (2) The present invention provides a spiral box in which sheet-packaged towels are stored in a tightly parallel arrangement. The spiral towel storage method of the spiral box allows the use of a very long spring and allows gravity and friction to participate in the transportation of the towels. This ensures that no matter how many towels are left, the storage and transportation pressures will not change greatly, and the towels will not be damaged while the transportation function is achieved. The spiral square spring with rounded corners can ensure uniform pushing force on the towels and avoid jamming. A long slow-rebound material block is provided at the front of the flexible push block, which can avoid damaging a portion of the towels at the storage end while performing the pushing function. The curved plate structure of the lower half of the Z-shaped action plate is provided with friction patterns, which is beneficial to reducing the pressure during storage and reducing towel damage.

[0018] (3) The present invention sets a Z-shaped action plate and an adjustment brush. When the industrial computer confirms the transaction, the spiral storage device starts to work, and the servo motor drives the Z-shaped action plate to rotate downward. The middle horizontal plate of the Z-shaped action plate pushes a packaged towel to move downward. At this time, the total width of the lower opening can allow the packaged towel to leave the end straight box downward, and the curved plate structure of the upper part of the Z-shaped action plate prevents the remaining towels from pouring out. When the Z-shaped action plate is retracted upward, the middle horizontal plate structure of the Z-shaped action plate is withdrawn upward, and the extra space can adjust the contact state between the next packaged towel and the lower part of the Z-shaped action plate to prevent jamming. When the packaged towel is pushed downward to the posture adjustment device by the Z-shaped action plate, the arc-shaped brush plate and the curved brush strip set by the adjustment brush constitute a uniform resistance in the horizontal direction, so that the packaged towel is decelerated and has a certain posture adjustment.

[0019] (4) The present invention provides a posture adjustment device. When the packaged towel falls between the two counter-rotating combined roller devices, the elastic ring provided at the elastic ring groove unit on the outer side of the rigid rod grasps the packaged towel and extrudes it for counter-rotation. At this time, if the packaged towel is tilted, the corner at the bottom first squeezes the rigid rod, so that the nonlinear spring in the rectangular deep groove closer to the corner is squeezed. The nonlinear spring can provide a certain range of screening tolerance. The linear speed of the elastic ring here is reduced. The packaged towel falls first and is squeezed and damped, thereby slowing down. Since it can slip with the elastic ring to a certain extent, the relative descending speed of the other corner of the packaged towel increases. The packaged towel is subjected to a greater posture adjustment. When its posture is corrected, the total friction between it and the elastic rings increases, and the slipping stops. At this time, the packaged towel is squeezed and transported downward.

[0020] (5) The present invention sets a multifunctional sliding member in the multi-state screening device. The multifunctional sliding member can divide the three working states into two execution results. If the total thickness of the towels transported by the posture adjustment device is abnormal, it means that a single towel has a large specification abnormality, or the number of towels pushed is abnormal. At this time, the adjustment wheel shaft of the combined roller device that can move laterally on the left side is excessively squeezed to the left. After the adjacent large gears lose engagement, the deformed belt along the synchronous belt can ensure that the adjacent large gears continue to rotate in opposite directions. Regardless of whether the extrusion displacement is insufficient or excessive, the rounded trapezoidal block of the multifunctional sliding member will not or will stop squeezing the double pulley slide rod device. At this time, the ramp slide bar will not hit the arrow-shaped guide device, and the goods will not be sent out, but fall into the collection box set in the lower right part of the vending machine.

[0021] (6) The present invention sets a multi-state screening device. If the total thickness of the towels transported by the posture adjustment device is normal, the slope slide bar hits the arrow-shaped guide device. The impact can transfer a smaller stroke to the light-load component, thereby generating an amplified stroke. The magnetic buffer strips set on both sides of the arrow-shaped guide device can greatly extend the service life of the impact part. At this time, the guide plate deflects to the right, and the goods are sent to the pickup slot through the concave slope plate. The slow-rebound coating layer coated with the metal spring of the delay spring can produce a certain delay, thereby reducing the difficulty of accurate screening. The anti-stuck roller can prevent the goods from getting stuck and reduce the impact damage to the goods. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The spiral storage device 4 includes a spiral box 401, a spiral square spring 402 is arranged at the upper inner portion of the spiral box 401, and a lower opening of the spiral box 401 is arranged. The terminal rectangular tube 403 has a flexible push block 404 which is slidably connected to the interior of the terminal rectangular tube 403. The sheet-packed towels are stored in the spiral box 401 in a tightly parallel arrangement. The spiral towel storage method of the spiral box 401 allows the use of a very long spring and allows gravity and friction to participate in the transportation process of the towels during transportation. All of these ensure that no matter how many towels are left, the storage and transportation pressure will not change greatly, and the towels will not be damaged while achieving the transportation function. The spiral square spring 402 with rounded corners can ensure that the pushing force on the towels is uniform and avoids getting stuck. The front part of the flexible push block 404 is provided with a long slow-rebound material block, which can avoid damaging a part of the towels at the storage end while performing the pushing function. The curved plate structure of the lower half of the Z-shaped action plate 407 is provided with friction patterns, which is conducive to reducing the pressure during storage and reducing towel damage. The higher flat side of the flexible push block 404 is fixedly connected to the lower end of the spiral square spring 402. The upper part of the open end of the terminal rectangular tube 403 is provided with an upper opening 405, the lower part of the open end of the terminal rectangular tube 403 is provided with a lower opening 406, and the open end of the terminal rectangular tube 403 is provided with a Z-shaped action plate 407 outwardly, and the side of the Z-shaped action plate 407 away from the open end of the terminal rectangular tube 403 is connected to the servo motor 408 through the rocker structure. When the industrial computer 2 confirms the transaction, the spiral storage device 4 starts to work, and the servo motor 408 drives the Z-shaped action plate 407 to rotate downward, and the middle part of the Z-shaped action plate 407 The horizontal plate pushes a packaged towel to move downward. At this time, the total width of the lower opening 406 allows the packaged towel to leave the end straight box 403 downward, and the curved plate structure of the upper part of the Z-shaped action plate 407 prevents the remaining towels from pouring out. When the Z-shaped action plate 407 is retracted upward, the middle horizontal plate structure of the Z-shaped action plate 407 is withdrawn upward, and the extra space can adjust the contact state between the next packaged towel and the lower part of the Z-shaped action plate 407 to prevent jamming.

[0037] The posture adjustment device 5 includes two counter-rotating combined roller devices, each of which includes an adjustment wheel shaft 501, and large gears 502 are fixedly connected to both ends of the cylindrical surface of the adjustment wheel shaft 501. A rectangular deep groove 503 is provided on the inner side of each large gear 502 near the gear teeth. Each rectangular deep groove 503 is arranged in a circular array. A nonlinear spring 504 is arranged inside each rectangular deep groove 503. One end of each nonlinear spring 504 is fixedly connected to the bottom surface of the corresponding rectangular deep groove 503 near the center direction of the large gear 502. A rigid rod 504 is provided between the rectangular deep grooves 503 opposite to the two large gears 502. 5. Each end of each rigid rod 505 is fixedly connected to one end of the corresponding nonlinear spring 504 away from the center of the large gear 502. When the packaged towel falls between the two counter-rotating combined roller devices, the elastic ring 507 arranged at the elastic ring groove unit 506 on the outer side of the rigid rod 505 grasps and counter-rotates and squeezes the packaged towel for transportation. At this time, if the packaged towel is tilted, the lower corner will first squeeze the rigid rod 505, so that the nonlinear spring 504 in the rectangular deep groove 503 closer to the corner will be squeezed. The nonlinear spring 504 can provide a certain range of screening tolerance.

[0038] An elastic ring groove unit 506 is provided at a position of the cylindrical surface of each rigid rod 505 away from the adjusting wheel shaft 501. The elastic ring groove units 506 located on the same circumference constitute an elastic ring groove structure. An elastic ring 507 is clamped inside each elastic ring groove structure. The rotation linear speed of the elastic ring 507 here is reduced, and the wrapped towel falls down first and is squeezed and damped, thereby slowing down. Since it can slip with the elastic ring 507 to a certain extent, the relative falling speed of the other corner of the wrapped towel increases, and the wrapped towel is subjected to a greater posture adjustment. When its posture is corrected, the total friction between it and the elastic rings 507 increases, and the slipping stops. At this time, the wrapped towel The towels are squeezed downward and transported, and the large gears 502 on the same side of the two combined roller devices are belt-connected with the synchronous belt 508, and an adjustment brush 509 is arranged in the middle above the two combined roller devices, and arc-shaped brush plates c1 are arranged on both sides of the adjustment brush 509, and the inner side wall of each arc-shaped brush plate c1 is arranged with a curved brush strip c2. When the packaged towels are pushed downward to the posture adjustment device 5 by the Z-shaped action plate 407, the arc-shaped brush plates c1 and the curved brush strips c2 arranged on the adjustment brush 509 constitute a uniform resistance in the horizontal direction, so that the packaged towels are decelerated and subjected to a certain posture adjustment, and a brushless motor 510 is arranged at one end of the adjustment wheel shaft 501 of the right combined roller device.

[0039] The multi-state screening device 6 includes a support beam 601, a long groove 602 is opened in the middle of the support beam 601, a multifunctional sliding member 603 is slidably connected to the outer side of the middle part of the support beam 601, the base of the multifunctional sliding member 603 is provided with a slider body a1, a sliding groove a2 is opened horizontally on the left side of the slider body a1, a bearing groove ring a3 is fixedly connected to the right side of the slider body a1, and a rounded trapezoidal block a4 is fixedly connected to the lower surface of the slider body a1. The multifunctional sliding member 603 is arranged corresponding to the long groove 602, and the multifunctional sliding member 603 can divide the three working states into two execution results.

[0040] The left end of the inner part of the long groove 602 is fixedly connected with a transverse spring 604, and the right end of the transverse spring 604 is fixedly connected to the outer cylindrical surface of the bearing groove ring a3. A double pulley slide rod device 605 is arranged below the multifunctional sliding member 603, and a ramp slide bar 606 is arranged below the double pulley slide rod device 605. An arrow-shaped guide device 607 is arranged on the right side of the ramp slide bar 606. If the total thickness of the towels transported by the posture adjustment device 5 is abnormal, it means that a single towel has a large specification abnormality, or the number of towels pushed is abnormal. At this time, the left The adjusting wheel shaft 501 of the combined roller device that can move laterally is excessively squeezed to the left. After the adjacent large gears 502 lose engagement, the deformed belt along the synchronous belt 508 can ensure that the adjacent large gears 502 continue to rotate in opposite directions. No matter the squeezing displacement is insufficient or excessive, the rounded trapezoidal block a4 of the multifunctional sliding member 603 will not or will stop squeezing the double pulley slide bar device 605. At this time, the slope slide bar 606 will not hit the arrow-shaped guide device 607, and the goods will not be sent out, but will fall into the collection box arranged in the lower right part of the vending machine.

The collision can transfer a smaller stroke to the light-load component, thereby generating an amplified stroke. The magnetic buffer strips b3 arranged on both sides of the arrow-shaped guide device 607 can greatly extend the service life of the impact part. At this time, the guide plate b2 deflects to the right, and the goods are sent to the picking slot 3 through the concave slope plate 608. The slow-rebound coating layer coated with the metal spring of the delay spring b4 can produce a certain delay, reducing the difficulty of accurate screening. The anti-stuck roller b5 can prevent the goods from getting stuck and reduce the impact damage to the goods.

[0042] Working principle: When the smart towel vending machine for convenient towel retrieval is used, consumers use payment methods such as mobile payment to enable the industrial computer 2 to drive the spiral storage device 4 and the posture adjustment device 5 to adjust the posture and take out the towels, and the multi-state screening device 6 to deliver the towels when they are taken out normally and collect the towels when they are taken out abnormally.

[0043] The sheet-packaged towels are stored in the spiral box 401 in a tightly parallel arrangement. The spiral towel storage method of the spiral box 401 allows the use of very long springs and allows gravity and friction to participate in the transportation process of the towels. All of these ensure that no matter how many towels are left, the storage and transportation pressure will not change greatly, and the towels will not be damaged while achieving the transportation function. The spiral square spring 402 with rounded corners can ensure that the pushing force on the towels is uniform and avoids jamming. The front part of the flexible push block 404 is provided with a longer slow-rebound material block, which can avoid damaging a part of the towels at the storage end while performing the pushing function. The curved plate structure of the lower half of the Z-shaped action plate 407 is provided with friction patterns, which is beneficial to reduce the pressure during storage and reduce towel damage.

[0044] After the industrial computer 2 confirms the transaction, the spiral storage device 4 starts to work, and the servo motor 408 drives the Z-shaped action plate 407 to rotate downward. The middle horizontal plate of the Z-shaped action plate 407 pushes a packaged towel to move downward. At this time, the total width of the lower opening 406 can allow the packaged towel to leave the end straight box 403 downward, and the curved plate structure of the upper part of the Z-shaped action plate 407 prevents the remaining towels from pouring out. When the Z-shaped action plate 407 is retracted upward, the middle horizontal plate structure of the Z-shaped action plate 407 is withdrawn upward, and the extra space can adjust the contact state between the next packaged towel and the lower part of the Z-shaped action plate 407 to prevent jamming.

[0045] When the packaged towel is pushed downward to the posture adjustment device 5 by the Z-shaped action plate 407, the arc-shaped brush plate c1 and the curved brush strip c2 provided by the adjustment brush 509 form a uniform resistance in the horizontal direction, so that the packaged towel is decelerated and has a certain posture adjustment.

[0046] When the packaged towel falls between the two counter-rotating combined roller devices, the industrial computer 2 has driven the brushless motor 510 to drive the large gear 502 to rotate, and the elastic ring 507 arranged at the elastic ring groove unit 506 on the outer side of the rigid rod 505 grasps and counter-rotates the towel for squeezing and conveying. At this time, if the packaged towel is tilted, the corner at the bottom first squeezes the rigid rod 505, so that the nonlinear spring 504 in the rectangular deep groove 503 close to this corner is squeezed. The nonlinear spring 504 can provide a certain range of screening tolerance. The linear speed of the elastic ring 507 here is reduced, and the packaged towel falls first and is squeezed and damped to decelerate. Since it can slip with the elastic ring 507 to a certain extent, the relative descending speed of the other corner of the packaged towel increases, and the packaged towel is subjected to a greater posture adjustment. When its posture is correct, the total friction between it and the elastic rings 507 increases, and the slipping stops. At this time, the packaged towel is squeezed and conveyed downward.

[0047] The multifunctional sliding member 603 can divide the three working states into two execution results. If the total thickness of the towels transported by the posture adjustment device 5 is abnormal, it means that a single towel has a larger specification abnormality, or the number of towels pushed is abnormal. At this time, the adjustment wheel shaft 501 of the combined roller device that can move laterally on the left is excessively squeezed to the left. After the adjacent large gears 502 lose engagement, the deformed belt along the synchronous belt 508 can ensure that the adjacent large gears 502 continue to rotate in opposite directions. Regardless of whether the extrusion displacement is insufficient or excessive, the rounded trapezoidal block a4 of the multifunctional sliding member 603 will not or will stop squeezing the double pulley slide rod device 605. At this time, the ramp slide bar 606 will not hit the arrow-shaped guide device 607, and the goods will not be sent out, but fall into the collection box set in the lower right part of the vending machine.

[0048] If the total thickness of the towels transported by the posture adjustment device 5 is normal, the slope slide 606 hits the arrow-shaped guide device 607. The collision can transfer a smaller stroke to the light-load component, thereby generating an amplified stroke. The magnetic buffer strips b3 arranged on both sides of the arrow-shaped guide device 607 can greatly extend the service life of the impact part. At this time, the guide plate b2 deflects to the right, and the goods are sent to the picking slot 3 through the concave slope plate 608. The slow-rebound coating layer coated with the metal spring of the delay spring b4 can produce a certain delay, reducing the difficulty of accurate screening. The anti-stuck roller b5 can prevent the goods from getting stuck and reduce the impact damage to the goods.
