Description

Technical Field

[0001] The present invention relates to the technical field of automatic stacking, and particularly to an automatic stacking device for a folding cart. Background Art

[0002] For many years, the bank vaults in our country have extremely strict management systems and operation requirements. Vault operations have always been mainly manual, with very little use of automated technologies and equipment. Even the relevant management systems rarely take into account the needs of automated and intelligent vault equipment. Therefore, the labor intensity is high, there are many risk points, and the management difficulty is large, which is the current situation faced by bank vaults. The inbound and outbound of various goods in vault management are basically completed by "loading and unloading by hand and carrying by walking". Although some mechanization upgrades have been carried out in some links, such as the sorting and handling links, for the entire vault, manual connection is still required between each functional module, and an effective closed loop has not been formed.

[0003] Currently, there is a lack of automated equipment for stacking carts. Usually, manual intervention is used, resulting in low work efficiency. At the same time, the application scenarios are not suitable for introducing a large amount of manpower. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: an automatic stacking device for a folding cart. It includes a bottom plate support, on the top of which an introduction device is fixedly connected. On the top of the bottom plate support, a lifting device is fixedly connected.

The guide rod is arranged on the top of the introduction device on both sides of the lifting device.

[0005] The introduction device includes an introduction top plate, on the top of which a first motor is fixedly connected. The driving shaft of the first motor penetrates through the top of the introduction top plate and is rotatably connected to the introduction top plate.

On the bottom of the introduction top plate, an introduction support is fixedly connected. On the top of the bottom plate support of the introduction top plate, at a position inside the arc-shaped rubber belt, a tension wheel assembly is fixedly connected. The bottom of the elastic roller assembly is rotatably connected to the top of the bottom plate support. The bottom of the introduction support is fixedly connected to the top of the bottom plate support. The driving shaft of the first motor is fixedly connected to the input end of the elastic roller assembly through a belt transmission mechanism. The top of the introduction top plate is fixedly connected to the bottom of the guide rod.

[0006] Preferably, the elastic roller assembly includes a roller shaft, a runner is sleeved and fixedly connected to the side surface of the roller shaft, a support shaft is fixedly connected to the bottom of the runner, a fixed wheel is sleeved and fixedly connected to the side surface of the support shaft, a spring piece is fixedly connected to the side surface of the fixed wheel, and the side surface of the spring piece is fixedly connected to the side surface of the arc-shaped rubber belt.

[0007] Preferably, the bottom of the support shaft is rotationally connected to the top of the bottom plate bracket. The side surface of the runner is fixedly connected to the drive shaft of the first motor through a belt transmission mechanism. The rotation of the fixed wheel drives the rotation of the spring piece, and the rotation of the spring piece drives the rotation of the arc-shaped rubber belt. The side surface of the arc-shaped rubber belt contacts the side surface of the trolley, thereby driving the trolley to move. The setting of the spring piece enables the trolley to always exert a lateral thrust on the trolley during the movement process, so that the trolley moves stably. The directional movement of the trolley is realized, and the applied elastic force enables the trolley to move stably.

[0008] Preferably, the lifting device includes a lifting frame. A second motor is fixedly connected to the bottom of the inner wall of the lifting frame. A sprocket transmission mechanism is fixedly connected to the drive shaft of the second motor. A lifting screw rod penetrates and is rotationally connected to the top of the inner wall of the lifting frame. The output end of the sprocket transmission mechanism is fixedly connected to the input end of the lifting screw rod. A lifting bottom plate is sleeved and threadedly connected to the side surface of the lifting screw rod. A stabilizing bracket is fixedly connected to the bottom of the lifting bottom plate. The lifting screw rod penetrates the top of the stabilizing bracket and is threadedly connected to the stabilizing bracket. A first sliding strip is fixedly connected to the side surface of the inner wall of the lifting frame. A sliding groove adapted to the first sliding strip is formed in the side surface of the lifting bottom plate. The lifting bottom plate is slidably connected to the lifting frame through the first sliding strip. The bottom of the lifting frame is fixedly connected to the top of the bottom plate bracket. The setting of the stabilizing bracket and the first sliding strip makes the movement of the lifting bottom plate more stable and not prone to shaking during the movement process, thereby avoiding the dropping of the trolley. The H-shaped design of the top of the lifting bottom plate increases the contact area with the bottom of the trolley, thereby further enhancing the stability. And due to the H-shaped design avoiding the position range of the trolley rollers, the top of the lifting bottom plate directly contacts the bottom of the trolley, thereby increasing the stability during the lifting process.

When the folding pressure plate starts to rotate, it drives the torsion spring to start compressing. The compression of the torsion spring generates an elastic force that drives the lower pressure frame to rotate along the folding rotating shaft. Since the elastic force of the torsion spring is less than the driving force of the folding pressure plate, the torsion spring lags behind the folding pressure plate in rotation. At the same time, the side surface of the lower pressure frame starts to contact the cart handle, and the lower pressure frame drives the anti-collision strip to closely adhere to the side surface of the cart handle. When the folding pressure plate rotates and moves by an angle, the handle lever is pressed down by the folding pressure plate, and the anti-collision strip closely adheres to the side surface of the cart handle. At this time, the torsion spring is compressed to the limit position, and the elastic force inside the torsion spring acts on the inner wall of the folding sleeve. The rotation of the folding sleeve drives the lower pressure frame to rotate, and the rotation of the lower pressure frame drives the anti-collision strip to rotate. The anti-collision strip closely adheres to the surface of the cart handle, so as to push the cart handle to fold after the folding pressure plate finishes pushing the handle lever, thus completing the folding operation of the cart handle. After the folding is completed, the third motor starts to rotate in the reverse direction. The third motor drives the folding rotating shaft to rotate in the reverse direction, and the folding rotating shaft drives the folding pressure plate to rotate in the reverse direction. The reverse rotation of the folding pressure plate drives the reset baffle to move, and the movement of the reset baffle drives the folding sleeve to rotate. The reverse rotation of the folding sleeve drives the lower pressure frame to rotate in the reverse direction, and at this time, the relative angle between the folding pressure plate and the folding sleeve is the same as the angle in the initial state. At this time, the inside of the torsion spring is in a relaxed state. The folding pressure plate rotates back under the driving action of the folding rotating shaft, and the side surface of the reset baffle is in contact with the side surface of the folding pressure plate. During the rotation back of the folding pressure plate, the folding pressure plate drives the reset baffle to move, and the movement of the reset baffle drives the folding sleeve to rotate. The rotation of the folding sleeve drives the lower pressure frame to reset, thus completing the folding process and then proceeding to the next repeated operation. The folding function of the cart handle is realized, and the assembly line operation of the folding cart can be achieved. At the same time, the operation is simple and the work process is convenient. The function of the rhombic air duct is to enhance the toughness when the lower pressure frame contacts the cart handle and conduct air, so as to extend the service life. The anti-collision strip is used for buffering to avoid leaving folding marks on the surface of the cart handle.

The air is sent into the inside of the rhombic air duct along the air duct after purification, and the air is released through the air outlet holes. When folding the cart handle, the cart surface is cleaned by the airflow, so as to facilitate storage. At the same time, the setting of the dust collection box is conducive to convenient cleaning. The surface of the cart is cleaned, and at the same time, the dust is collected, which is beneficial to the storage of the cart.

[0014] The present invention provides an automatic stacking device for a folding cart. It has the following beneficial effects:

[0015] 1. In this automatic stacking device for the folding cart, a fixed wheel is provided to rotate and drive a spring piece to rotate. The rotation of the spring piece drives an arc-shaped rubber belt to rotate. The side of the arc-shaped rubber belt contacts the side of the cart, thereby driving the small cart to move. The setting of the spring piece enables the cart to always exert a lateral thrust on the cart during the moving process, so that the cart moves stably. The directional movement of the cart is realized, and the applied elastic force enables the cart to move stably.

[0016] 2. In this automatic stacking device for the folding cart, the setting of the stable support and the first slide strip makes the movement of the lifting bottom plate more stable. During the movement of the lifting bottom plate, it is not easy to shake, thereby avoiding the cart from falling. The H-shaped design on the top of the lifting bottom plate increases the contact area with the bottom of the cart, thereby further enhancing the stability. And due to the H-shaped design avoiding the position range of the cart rollers, the top of the lifting bottom plate directly contacts the bottom of the cart, so the stability is increased during the lifting process.

[0017] 3. The automatic stacking device of this folding trolley is set such that when the folding pressing plate starts to rotate, it drives the torsion spring to start compressing. The compression of the torsion spring generates elastic force, which drives the lower pressing frame to rotate along the folding rotating shaft. Since the elastic force of the torsion spring is less than the driving force of the folding pressing plate, the torsion spring lags behind the folding pressing plate in rotation. At the same time, the side of the lower pressing frame starts to contact the trolley handle, and the lower pressing frame drives the anti-collision strip to closely adhere to the side of the trolley handle. When the folding pressing plate rotates and moves by an angle, the handle lever is pressed down by the folding pressing plate, and the anti-collision strip closely adheres to the side of the trolley handle. At this time, the torsion spring is compressed to the limit position, and the internal elastic force of the torsion spring acts on the inner wall of the folding sleeve. The rotation of the folding sleeve drives the lower pressing frame to rotate, and the rotation of the lower pressing frame drives the anti-collision strip to rotate. The anti-collision strip closely adheres to the surface of the trolley handle, so as to push the trolley handle to fold after the folding pressing plate finishes pushing the handle lever, thus completing the folding operation of the trolley handle. After the folding is completed, the third motor starts to rotate in the reverse direction. The third motor drives the folding rotating shaft to rotate in the reverse direction, and the folding rotating shaft drives the folding pressing plate to rotate in the reverse direction. The reverse rotation of the folding pressing plate drives the reset baffle to move, and the movement of the reset baffle drives the folding sleeve to rotate. The reverse rotation of the folding sleeve drives the lower pressing frame to rotate in the reverse direction, and at this time, the relative angle between the folding pressing plate and the folding sleeve is the same as the angle in the initial state. At this time, the inside of the torsion spring is in a relaxed state. The folding pressing plate rotates back under the driving action of the folding rotating shaft, and the side of the reset baffle contacts the side of the folding pressing plate. During the rotation-back process of the folding pressing plate, the folding pressing plate drives the reset baffle to move, and the movement of the reset baffle drives the folding sleeve to rotate. The rotation of the folding sleeve drives the lower pressing frame to reset, thus completing the folding process and then proceeding to the next repetitive operation. It realizes the folding function of the trolley handle, and can realize the assembly-line operation of the folding trolley. At the same time, the operation is simple and the work process is convenient. The function of the rhombic air duct is to enhance the toughness when the lower pressing frame contacts the trolley handle and conduct air, so as to extend the service life. The anti-collision strip is used for buffering to avoid leaving folding marks on the surface of the trolley handle.

[0018] 4. The automatic stacking device of this folding trolley is set such that the rotation of the electric fan drives the air to pass through the inside of the dust collection housing. The air is purified through the filtering action of the air filter. The dust falls under the action of gravity and is concentrated inside the dust collection box, thus facilitating cleaning. After the air is purified, it is sent into the inside of the rhombic air duct along the air duct, and the air is released through the air outlet holes. When folding the trolley handle, the surface of the trolley is cleaned by the air flow, thus facilitating storage. At the same time, the setting of the dust collection box is conducive to convenient cleaning. It realizes the cleaning of the surface of the trolley and the collection of dust, thus facilitating the storage of the trolley. Description of the Drawings

[0037] Please refer to Figures 1 - 5 As shown in [Figure X], the present invention provides a technical solution: The lifting device 3 includes a lifting frame 301.

[0039] Please refer to Figures 1 - 8 , the present invention provides a technical solution: The folding device 4 includes a folding base 401, a third motor 402 is fixedly connected to the side of the folding base 401, the drive shaft of the third motor 402 penetrates the side of the folding base 401 and is rotatably connected to the folding base 401, a folding rotating shaft 403 is fixedly connected to the drive shaft of the third motor 402, a folding pressing plate 404 is sleeved and fixedly connected to the side of the folding rotating shaft 403, an anti-slip pad 405 is fixedly connected to the side of the folding pressing plate 404, a handle folding assembly 406 is sleeved and rotatably connected to the folding rotating shaft 403, the handle folding assembly 406 is arranged between multiple groups of the folding pressing plates 404, a dust removal assembly 407 is fixedly connected to the top of the folding base 401, and the side of the folding base 401 is fixedly connected to the side of the bottom plate bracket 1.

[0040] The handle folding assembly 406 includes a folding sleeve 4061, a spring opening 4062 is formed on the side of the folding sleeve 4061, a torsion spring 4063 is fixedly connected to the inner side surface of the spring opening 4062, a reset baffle 4064 is fixedly connected to the side of the folding sleeve 4061, a pressing-down frame 4065 is fixedly connected to the top of the folding sleeve 4061, an anti-collision strip 4066 is fixedly connected to the side of the pressing-down frame 4065, a rhombic air duct 4067 is fixedly connected to the side of the pressing-down frame 4065, an air outlet 4068 is formed on the side of the pressing-down frame 4065 between the anti-collision strips 4066, the air outlet 4068 is communicated with the inner wall of the rhombic air duct 4067, one end of the torsion spring 4063 away from the folding sleeve 4061 is fixedly connected to the side of the folding pressing plate 404, the side of the reset baffle 4064 is in contact with the side of the folding pressing plate 404, the side of the rhombic air duct 4067 is communicated with the input end of the dust removal assembly 407, and the folding sleeve 4061 is sleeved on the folding rotating shaft 403 and is rotatably connected to the folding rotating shaft 403.

[0041] Working principle: When the trolley enters the designated position, the operator starts the third motor 402. The drive shaft of the third motor 402 drives the folding rotating shaft 403 to rotate. The rotation of the folding rotating shaft 403 drives the folding pressure plate 404 to rotate. The folding pressure plate 404 presses down on the joystick of the trolley, thereby releasing the trolley handle so that the trolley can be folded. The downward movement of the folding pressure plate 404 drives the torsion spring 4063 to start compressing. The torsion spring 4063 is pre-set in a relaxed state. When the folding pressure plate 404 starts to rotate, it drives the torsion spring 4063 to start compressing. The compression of the torsion spring 4063 generates elastic force to drive the lower pressure frame 4065 to rotate along the folding rotating shaft 403. Since the elastic force of the torsion spring 4063 is less than the driving force of the folding pressure plate 404, the torsion spring 4063 lags behind the folding pressure plate 404 in rotation. At the same time, the side surface of the lower pressure frame 4065 comes into contact with the trolley handle, and the lower pressure frame 4065 drives the anti-collision strip 4066 to closely adhere to the side surface of the trolley handle. When the folding pressure plate 404 rotates and moves by a certain angle, the handle joystick is pressed down by the folding pressure plate 404, and the anti-collision strip 4066 closely adheres to the side surface of the trolley handle. At this time, the torsion spring 4063 is compressed to the limit position, and the elastic force inside the torsion spring 4063 acts on the inner wall of the folding sleeve 4061. The rotation of the folding sleeve 4061 drives the lower pressure frame 4065 to rotate, and the rotation of the lower pressure frame 4065 drives the anti-collision strip 4066 to rotate. The anti-collision strip 4066 closely adheres to the surface of the trolley handle, so as to push the trolley handle to fold after the folding pressure plate 404 finishes pushing the handle joystick, thus completing the folding operation of the trolley handle. After the folding is completed, the third motor 402 starts to rotate in the reverse direction. The third motor 402 drives the folding rotating shaft 403 to rotate in the reverse direction. The folding rotating shaft 403 drives the folding pressure plate 404 to rotate in the reverse direction. The reverse rotation of the folding pressure plate 404 drives the reset baffle 4064 to move. The movement of the reset baffle 4064 drives the folding sleeve 4061 to rotate. The reverse rotation of the folding sleeve 4061 drives the lower pressure frame 4065 to rotate in the reverse direction, and at this time, the relative angle between the folding pressure plate 404 and the folding sleeve 4061 is the same as the angle in the initial state. At this time, the inside of the torsion spring 4063 is in a relaxed state. The folding pressure plate 404 rotates back under the driving action of the folding rotating shaft 403, and the side surface of the reset baffle 4064 comes into contact with the side surface of the folding pressure plate 404. During the rotation-back process of the folding pressure plate 404, the folding pressure plate 404 drives the reset baffle 4064 to move. The movement of the reset baffle 4064 drives the folding sleeve 4061 to rotate. The rotation of the folding sleeve 4061 drives the lower pressure frame 4065 to reset, thus completing the folding process and then proceeding to the next repetitive operation.The folding function of the trolley handle is realized, and the pipelining operation of the folding trolley can be achieved. Meanwhile, the operation is simple and the work process is convenient. The function of the rhombic air duct 4067 is to enhance the toughness when the pressing frame 4065 contacts the trolley handle and conduct air, thereby extending the service life. The anti-collision strip 4066 is used for buffering to avoid leaving folding marks on the surface of the trolley handle.

[0042] Please refer to Figures 1 - 11 , the present invention provides a technical solution: the dust removal assembly 407 includes a dust removal housing 4071, a side of the dust removal housing 4071 is communicated with an air duct 4072, an electric fan 4073 is fixedly connected to an inner wall of the dust removal housing 4071, a dust collection assembly 4074 is slidably connected to a part of the inner wall of the dust removal housing 4071 on one side of the electric fan 4073, a bottom of the dust removal housing 4071 is fixedly connected to a top of the folding base 401, and an end of the air duct 4072 away from the dust removal housing 4071 is communicated with a side of the rhombic air duct 4067.

[0043] The dust collection assembly 4074 includes a dust collection housing 40741, a lifting handle 40742 is fixedly connected to a side of the dust collection housing 40741, an air filter 40743 is fixedly connected to a side of the dust collection housing 40741, a dust collection box 40744 is fixedly connected to a bottom of the dust collection housing 40741, and a side of the dust collection housing 40741 is slidably connected to the inner wall of the dust removal housing 4071.

[0044] Working principle: The operator turns on the power supply of the electric fan 4073, and the rotation of the electric fan 4073 drives the air to pass through the inside of the dust collection housing 40741. The air is purified through the filtering function of the air filter 40743. The dust falls under the action of gravity and is concentrated inside the dust collection box 40744, thus facilitating cleaning. The purified air is sent into the rhombic air duct 4067 along the air duct 4072, and the air is released through the air outlet 4068. When folding the trolley handle, the surface of the trolley is cleaned by the air flow, thus facilitating storage. At the same time, the setting of the dust collection box 40744 is conducive to convenient cleaning. The cleaning of the trolley surface is realized, and at the same time, the dust is collected, which is conducive to the storage of the trolley.
