Description

Technical Field

[0001] This invention relates to the field of transportation equipment, and in particular to a pallet loading and unloading device and method. Background Technology

[0002] Pallets, also known as plastic pallets, are an indispensable basic piece of equipment in modern logistics warehousing. They are often used in conjunction with forklifts, racks, and other logistics equipment, primarily for storing, loading, and handling various goods. The emergence of plastic pallets is both a positive response to environmental demands—replacing traditional wooden pallets with plastic pallets effectively reduces deforestation and achieves green logistics—and an inevitable trend in the logistics industry. With food safety awareness growing and pharmaceutical companies increasingly demanding higher hygiene standards, plastic pallets, with their superior properties such as corrosion resistance, moisture resistance, rust resistance, insect resistance, and mold resistance, have gained high recognition and widespread application in the food and pharmaceutical industries. Furthermore, plastic pallets, due to their high load-bearing capacity and long service life, are also finding stellar performance in various fields such as chemicals, textiles, and manufacturing.

[0003] However, problems arise during actual use. After the plastic pallets have finished their task, they are usually placed directly on the ground. If these pallets need to be moved and stacked or distributed individually, the existing methods are either to use forklifts or to rely on manual handling. The former is limited by the large range of motion of forklifts, making operation inconvenient and inflexible, and difficult to complete the task accurately and efficiently; the latter, due to the large weight of the plastic pallets themselves, is not only time-consuming and laborious to handle manually, but also easily leads to physical exhaustion of workers, resulting in low handling efficiency and failing to meet the needs of efficient operation of modern logistics warehousing. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a pallet loading and unloading device capable of handling pallets loading and unloading.

[0005] The present invention also proposes a method for pallet loading and unloading with the above-mentioned pallet loading and unloading device.

[0006] On one hand, the pallet loading and unloading device according to an embodiment of the present invention includes:

[0007] The frame includes a frame body and two support arms. The two support arms extend from both ends of the frame body, forming a receiving groove and a first outlet. The support arms are provided with a second outlet.

[0008] A support mechanism is provided on the lower side of the frame. The support mechanism includes a support frame and a first drive assembly. The first drive assembly can drive the support frame to move in a direction closer to or farther from the first outlet.

[0010] A mobile power mechanism is provided on the frame, and the mobile power mechanism is used to drive the frame to move;

[0011] A feeding mechanism is provided on the supporting mechanism, the feeding mechanism being used to drive the pallet from the receiving groove to the second outlet.

[0012] According to some embodiments of the present invention, the feeding mechanism includes:

[0013] The material pusher is slidably disposed on the support frame;

[0014] The fourth drive component is capable of driving the pusher to move between the two support arms.

[0015] According to some embodiments of the present invention, the pushing part is provided with a swing arm and a swing drive, the swing arm is rotatably disposed on the pushing part, and the swing drive is used to drive the swing arm to rotate.

[0016] According to some embodiments of the present invention, the support frame is provided with a plurality of rollers, and the rolling of the rollers is according to some embodiments of the present invention. The support mechanism further includes at least two guide rods, the guide rods being respectively disposed on the two support arms, and the two ends of the support frame being slidably disposed on the guide rods.

[0017] According to some embodiments of the present invention, the first drive assembly includes at least two first drive shafts and a first power member. The first drive shafts are respectively disposed on the two support arms. The first drive shafts are respectively connected to both ends of the support frame. The first power member can simultaneously drive all the first drive shafts to rotate, so that the multiple first drive shafts are synchronously driven with the support frame.

[0018] According to some embodiments of the present invention, the support mechanism is provided in multiple ways, and the multiple support mechanisms are arranged sequentially in the front-to-back direction on the frame.

[0019] According to some embodiments of the present invention, the second driving component includes:

[0020] A first bracket is provided on the support arm, and the insert plate is slidably provided on the first bracket;

[0021] A drive belt is connected to the insert plate;

[0022] A second drive shaft is rotatably mounted on the first bracket, and the second drive shaft is connected to the transmission belt so that the insert plate can slide on the first bracket;

[0023] The second power component can drive the second drive shaft to rotate, so that the second drive shaft drives the transmission belt to make the insert slide.

[0024] According to some embodiments of the present invention, multiple insert plates and multiple transmission belts are provided, and the insert plates and the transmission belts are arranged in a one-to-one correspondence. The second drive shaft can drive multiple transmission belts simultaneously, so that multiple insert plates move simultaneously.

[0025] According to some embodiments of the present invention, the two second drive components share the same second power component, and the second power component drives the second drive shaft to rotate respectively through a transmission structure.

[0026] According to some embodiments of the present invention, the third driving component includes;

[0027] The second bracket is slidably disposed on the support arm, and the second drive assembly is disposed on the second bracket;

[0028] A third drive shaft is rotatably mounted on the second bracket, and the third drive shaft is connected to the frame;

[0029] The third power component can drive the third drive shaft to rotate, so that the second bracket can slide up and down relative to the frame.

[0030] According to some embodiments of the present invention, the two third drive components share the same third power member, and the third power member drives the third drive shaft to rotate through a transmission structure.

[0031] On the other hand, according to an embodiment of the present invention, the pallet loading and unloading method includes the following steps:

[0032] Upon entering the warehouse, the mobile power mechanism drives the frame, causing the pallets to enter the receiving slot from the first outlet;

[0033] The second drive assembly drives the two insert plates to be inserted into both sides of the bottommost stack plate, and the third drive assembly drives the stack plate to move upward.

[0034] The first drive assembly drives the support frame to move under the stack, and the second drive assembly drives the insert plate away from the stack, so that the stack is placed on the support frame.

[0035] In the sorting process, the third drive assembly drives the insert plate to move upward to align with the second pallet from the bottom up, the second drive assembly drives the two insert plates to be inserted into both sides of the pallet respectively, and the third drive assembly drives the pallet to move upward.

[0036] Upon exiting the warehouse, the feeding mechanism drives the pallets on the support frame to be discharged from the second outlet.

[0037] On the other hand, the pallet loading and unloading method according to an embodiment of the present invention includes a pallet loading and unloading device according to the above embodiment of the present invention.

[0038] The embodiments of the present invention have at least the following beneficial effects:

[0039] Its mobile rack design allows it to move flexibly between warehouses and work areas. The receiving slot formed by the support arm and the first outlet efficiently receive (inbound) pallets. Combining the load-bearing function of the support mechanism with the pushing function of the feeding mechanism, it achieves end-to-end transport of pallets from the ground to the storage location (inbound) and from the storage location to the designated output point (outbound), significantly improving material flow efficiency.

[0040] Its second drive component precisely controls the horizontal insertion of the pallet into both sides of a designated pallet layer, while the third drive component enables the vertical lifting and lowering of that pallet layer. This mechanism allows the device to not only lift the entire pallet stack to meet transportation or storage height requirements, but also to accurately separate and extract specific layers (such as the second layer from the bottom). This provides key technical support for subsequent layered outbound operations, compact stacking, or retrieval of specific pallet layers, effectively optimizing warehouse space utilization.

[0041] The support mechanism (support frame) is controlled by the first drive assembly and can intervene promptly after the height adjustment mechanism lifts the stack of pallets, firmly supporting the entire stack. The height adjustment mechanism then safely releases the bottom layer (by retracting the insert plate), completely transferring the weight to the support frame, ensuring stability and safety during transportation and storage. The support frame also provides reliable support for the bottommost stack of pallets when a specific layer needs to be removed from storage.

[0042] The inbound and outbound processes have separate exits. Operators typically stand at the first exit for easy observation and alignment with the pallets. This also allows for better visibility, enabling operators to apply force at the first exit to prevent the pallets from tipping over. Standing opposite the first exit, especially with a large number of pallets, obstructs the view and hinders operation. If the outbound process is at the first exit, operators must maneuver to avoid it, making operation inconvenient. However, if the outbound process is located at the support arm, operators do not need to maneuver; simply adjusting the frame position allows for pallet discharge, facilitating control.

[0043] The entire process of pallet warehousing, lifting, supporting, layering, positioning, and designated layer retrieval requires virtually no direct manual intervention in handling or manipulating the pallets themselves. The operator's main task is simplified to controlling the movement direction of the rack. This not only greatly reduces the physical burden on operators and avoids the safety risks of handling heavy objects, but also significantly reduces reliance on skilled workers, allowing a single person to easily manage multiple units or multiple pallets, thus improving overall efficiency.

[0044] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0067] Reference Figures 1-8 A basic embodiment of the first aspect of the present invention provides a pallet loading and unloading device, comprising:

[0068] The frame 100 includes a frame 100 body and two support arms 120. The two support arms 120 extend from both ends of the frame 100 body, so that the frame 100 forms a receiving groove 130 and a first outlet 140. The support arms 120 are provided with a second outlet 150.

[0069] The support mechanism 200 is located on the lower side of the frame 100. The support mechanism 200 includes a support frame 210 and a first drive assembly. The first drive assembly can drive the support frame 210 to move in a direction close to or away from the first outlet 140.

[0070] Two height adjustment mechanisms 300 are respectively provided on two support arms 120. Each height adjustment mechanism 300 includes a plate 310, a second drive assembly 320 and a third drive assembly 330. The second drive assembly 320 can drive the plate 310 to move between the two support arms 120, and the third drive assembly 330 can drive the plate 310 to move in the vertical direction.

[0071] A moving power mechanism 400 is provided on the frame 100 and is used to drive the frame 100 to move.

[0072] The feeding mechanism 500 is located on the supporting mechanism 200 and is used to drive the pallet from the receiving groove 130 to the second outlet 150.

[0073] A basic embodiment of the second aspect of the present invention provides a method for pallet loading and unloading, applied to a pallet loading and unloading device, characterized by comprising the following steps:

[0074] Upon entering the warehouse, the moving power mechanism 400 drives the frame 100, causing the pallet to enter the receiving groove 130 from the first outlet 140.

[0075] The second drive assembly 320 drives two insert plates 310 to be inserted into both sides of the bottommost stack plate, and the third drive assembly 330 drives the stack plate to move upward.

[0076] The first drive assembly drives the support frame 210 to move under the stack, and the second drive assembly 320 drives the insert plate 310 away from the stack, so that the stack is placed on the support frame 210.

[0077] In the sorting process, the third drive assembly 330 drives the insert plate 310 to move upward to align with the second pallet from bottom to top, the second drive assembly 320 drives the two insert plates 310 to insert into both sides of the pallet respectively, and the third drive assembly 330 drives the pallet to move upward.

[0078] Upon exiting the warehouse, the feeding mechanism 500 drives the pallets on the support frame 210 to be discharged from the second outlet 150.

[0079] According to embodiments of the present invention, this arrangement achieves at least the following effects: the mobile rack 100 is designed to move flexibly between warehouses or work areas; the receiving slot 130 formed by the support arm 120 and the first outlet 140 efficiently receive (inbound) pallets; and by combining the carrying function of the supporting mechanism 200 with the pushing function of the feeding mechanism 500, the entire process of pallet transport from the ground to the storage location (inbound) and from the storage location to the designated output point (outbound) is realized, significantly improving material flow efficiency.

[0080] Its second drive component 320 can precisely control the horizontal insertion of the insert plate 310 into both sides of a designated pallet layer, while the third drive component 330 realizes the vertical lifting and lowering of that pallet layer. This mechanism enables the device not only to lift the entire pallet stack to meet transportation or storage height requirements, but also to accurately separate and extract specific layers (such as the second layer from the bottom). This provides key technical support for subsequent layered outbound operations, compact stacking, or retrieval of specific pallet layers, effectively optimizing warehouse space utilization.

[0081] The support mechanism 200 (support frame 210) is controlled by the first drive assembly to intervene promptly after the height adjustment mechanism 300 lifts the stack of pallets, providing stable support for the entire stack. The height adjustment mechanism 300 then safely releases the bottom layer (retracting via the insert plate 310), completely transferring the weight to the support frame 210, ensuring stability and safety during transportation and storage. The support frame 210 can also provide reliable support for the bottommost stack of pallets when a specific layer needs to be removed from storage.

[0082] The inbound and outbound processes have separate exits. Operators typically stand at the first exit (140) for easy observation of its position and alignment with the pallet. This also allows for better visibility of the area ahead, enabling operators to apply force at the first exit (140) to prevent the pallet from tipping over. Standing opposite the first exit (140) can obstruct the view, especially with a large number of pallets, and is also disadvantageous for operation if standing on the side of the support arm (120). If the outbound process is located at the first exit (140), operators need to move aside, which is inconvenient. However, if the outbound process is located at the support arm (120), operators do not need to move aside; simply adjusting the frame (100) allows the pallet to be discharged, facilitating control.

[0083] The entire process of pallet warehousing, lifting, supporting, layering, positioning, and designated layer retrieval requires virtually no direct manual intervention in handling or manipulating the pallets themselves. The operator's main task is simplified to controlling the movement direction of the frame 100. This not only greatly reduces the physical burden on operators and avoids the safety risks of handling heavy objects, but also significantly reduces reliance on skilled workers, allowing a single person to easily manage multiple devices or multiple pallets, thus improving overall efficiency.

[0084] It should be noted that the mobile power mechanism 400 is the main driving mechanism for the movement of the frame 100. It is a conventional technical means and can refer to existing vehicle movement structures, including front and rear wheels and steering structure. It can drive the frame 100 to move in the front, back, left and right directions, so that the frame 100 can move to different positions to perform pallet loading and unloading operations.

[0085] It should be noted that the power unit of this device mainly transmits power through belts and shafts. Although the power components are relatively far apart, the power can be transmitted to the device through the transmission connection of belts or shafts.

[0086] It should be noted that the power components of this device are mainly common power structures such as rotary motors, cylinders, or linear motors.

[0087] Based on the basic embodiment of the first aspect, a pallet transport device is provided, wherein the support arm 120 does not have a second outlet 150, nor a feeding mechanism 500, that is, it includes:

[0088] The frame 100 includes a frame 100 body and two support arms 120. The two support arms 120 extend from both ends of the frame 100 body, so that the frame 100 forms a receiving groove 130 and a first outlet 140.

[0089] The support mechanism 200 is located on the lower side of the frame 100. The support mechanism 200 includes a support frame 210 and a first drive assembly. The first drive assembly can drive the support frame 210 to move in a direction close to or away from the first outlet 140.

[0090] Two height adjustment mechanisms 300 are respectively provided on two support arms 120. Each height adjustment mechanism 300 includes a plate 310, a second drive assembly 320 and a third drive assembly 330. The second drive assembly 320 can drive the plate 310 to move between the two support arms 120, and the third drive assembly 330 can drive the plate 310 to move in the vertical direction.

[0091] A moving power mechanism 400 is provided on the frame 100 and is used to drive the frame 100 to move.

[0092] In this setup, the inbound method is the same as in the basic embodiment, while the outbound method is to discharge from the first outlet 140. The height adjustment mechanism 300 will lift the second pallet from the bottom up. The moving frame 100 can keep the bottom pallet in place, or the supporting mechanism 200 can move towards the direction closer to the first outlet 140 to push the bottom pallet out of the frame 100.

[0093] In some embodiments, a stacking step is also included. After the warehousing and lifting steps, the rack 100 is moved to another stack, so that the other stack enters the receiving slot 130 from the first inlet. The second drive assembly 320 drives the insert plate 310 away from the stack, so that the stacks are stacked. The lifting step is repeated to lift the bottom stack and the stack above it together.

[0094] In some embodiments, a first embodiment of the feeding mechanism 500 includes:

[0095] The pusher part 510 is slidably mounted on the support frame 210;

[0096] The fourth drive assembly is capable of driving the pusher 510 to move between the two support arms 120.

[0097] In this configuration, the pusher 510 moves back and forth on the support arm 120 bracket, causing the pusher 510 to abut against the stack plate, allowing the stack plate to be discharged from the receiving groove 130 towards the second outlet. The fourth drive assembly can be a linear motor or a shaft-driven belt drive.

[0098] In some embodiments, the pusher 510 is provided with a swing arm 511 and a swing drive 512. The swing arm 511 is rotatably disposed on the pusher 510, and the swing drive 512 is used to drive the swing arm 511 to rotate.

[0099] In this configuration, by driving the swing arm 511 to rotate, the swing arm 511 can be in a working state capable of pushing the stack. At this time, the height of the swing arm 511 is relatively high, which can be understood as the swing arm 511 pointing upward or tilted upward. The height of the swing arm 511 is greater than the height of the upper surface of the support frame 210, so that the swing arm 511 can drive the stack on the support frame 210 to move. By driving the swing arm 511 to rotate, the swing arm 511 can be in a non-working state. At this time, the height of the swing arm 511 is relatively low, which can be understood as the swing arm 511 pointing downward, horizontally, or tilted downward. The height of the swing arm 511 is relatively low, which can be understood as the swing arm 511 pointing downward, horizontally, or tilted downward. The height of the swing arm 511 is less than the height of the upper surface of the support frame 210, so that the swing arm 511 cannot drive and abut against the stack, preventing the upper stack from moving when the support structure moves during the support step.

[0100] Furthermore, the swing drive 512 can be a rotary motor that can drive the swing arm 511 to rotate, or the swing drive 512 can be a telescopic power component such as a telescopic motor that can drive the swing arm 511 to move up and down.

[0101] In some embodiments, a second embodiment of the feeding mechanism 500 includes a drive wheel disposed on a support frame 210, which drives a stack of pallets on the support frame 210 to move along the support frame 210. The drive wheel on the support frame 210 enables the stack of pallets to move along the support frame 210.

[0102] In some embodiments, the support frame 210 is provided with a plurality of rollers 211, the rollers 211 rolling in the direction of the support arm 120. The rollers 211 effectively reduce the friction between the support frames 210 of the stack, which is beneficial for the feeding mechanism 500 to move the stack. Secondly, since the rollers 211 are oriented towards the support arm 120, the support arm 120 acts as a blocking force against the stack, while there is no force or a small force in the direction towards the first outlet 140, preventing the stack from being discharged in the direction of the first outlet 140.

[0103] In some embodiments, the support mechanism 200 further includes at least two guide rods 220, which are respectively disposed on the two support arms 120, and the two ends of the support frame 210 are slidably disposed on the guide rods 220. The guide rods 220 are used to support the support mechanism 200 and guide the movement of the support frame 210, so that the support frame 210 can move in a predetermined direction.

[0104] In some embodiments, the first drive assembly includes at least two first drive shafts 230 and a first power member 240. The first drive shafts 230 are respectively disposed on two support arms 120. The first drive shafts 230 are respectively connected to both ends of the support frame 210. The first power member 240 can drive all the first drive shafts 230 to rotate simultaneously, so that the multiple first drive shafts 230 are synchronously driven with the support frame 210.

[0105] In some embodiments, multiple support mechanisms 200 are provided, and the multiple support mechanisms 200 are arranged sequentially in the front-to-back direction on the frame 100.

[0106] In some embodiments, the second driving component 320 includes:

[0107] The first bracket 321 is provided on the support arm 120, and the insert plate 310 is slidably provided on the first bracket 321;

[0108] The drive belt 322 is connected to the insert plate 310;

[0109] The second drive shaft 323 is rotatably mounted on the first bracket 321. The second drive shaft 323 is connected to the transmission belt 322, so that the insert plate 310 can slide on the first bracket 321.

[0110] The second power component 324 can drive the second drive shaft 323 to rotate, so that the second drive shaft 323 drives the transmission belt 322 to make the insert plate 310 slide.

[0111] In this configuration, the second drive shaft 323 is driven to rotate by the second power component 324. The second drive shaft 323 can drive the transmission belt 322 to work, and the insert plate 310 can slide relative to the first bracket 321 under the action of the transmission belt 322.

[0112] Furthermore, multiple insert plates 310 and transmission belts 322 are provided, with each insert plate 310 and transmission belt 322 corresponding to the other. The second drive shaft 323 can simultaneously drive multiple transmission belts 322, causing multiple insert plates 310 to move simultaneously. By using a single second drive shaft 323 to move the insert plates 310 simultaneously, the use of power components is reduced, effectively saving costs.

[0113] In some embodiments, the two second drive components 320 share the same second power member 324, which drives the second drive shaft 323 to rotate via a transmission structure. The two second drive components share the same power structure, enabling the insert plates 310 on the two support arms 120 to move closer or further apart synchronously, preventing the insert plate 310 on one side from being inserted while the insert plate 310 on the other side cannot be inserted.

[0114] It should be noted that the power drive component of the second drive assembly 320 can also be a telescopic motor. It is also equipped with a first bracket 321 and an insert plate 310 slidably disposed on the first bracket 321. The telescopic motor can drive the insert plate 310 to slide based on the first bracket 321, so that the insert plate 310 can be inserted into the stack plate.

[0115] In some embodiments, the third drive component 330 includes;

[0116] The second bracket 331 is slidably mounted on the support arm 120, and the second drive assembly 320 is mounted on the second bracket 331;

[0117] The third drive shaft 332 is rotatably mounted on the second bracket 331, and the third drive shaft 332 is connected to the frame 100;

[0118] The third power component 333 can drive the third drive shaft 332 to rotate, so that the second bracket 331 can slide up and down relative to the frame 100.

[0119] In this configuration, the first support 321 can slide relative to the frame 100. The second support 331 is driven to slide up and down by the third drive shaft 332. The third power component 333 drives the third drive shaft 332 to rotate. The second support 331 is connected to the third rotating shaft by a lead screw, which enables the second support 331 to slide up and down. The second drive assembly 320 is mounted on the second support 331 and can drive the second drive assembly 320 to slide up and down, so that the insert plate 310 can slide up and down. During the up and down sliding of the insert plate 310, the change in the position of the insert plate 310 will also cause the height of the second outlet 150 to change. The increase in the height of the insert plate 310 allows the stack plate located on the support mechanism 200 to be discharged from the second outlet 150 to the outside of the device.

[0120] Furthermore, the two third drive components 330 share the same third power component 333, which drives the third drive shaft 332 to rotate through a transmission structure. The two second drive components share the same power structure, enabling the second drive components 320 to move up and down synchronously, that is, the insert plates 310 to move up and down synchronously, ensuring that the insert plates 310 on the left and right sides are at the same height, and that the stack plates in between can also maintain balance.

[0121] In some embodiments, the support portion has a guide surface on the side near the first outlet 140, and the guide surface is inclined to the receiving groove 130. The guide surface can be chamfered or rounded, and when the guide surface abuts against the stack plate, it can cause the stack plate to slide inward, so that the stack plate has a high fault tolerance when entering the receiving groove 130.
