Description

Technical Field

[0001] The present invention belongs to the technical field of logistics unloading, and specifically to an e-commerce logistics unloading and inspection platform. Background Art

[0002] When e-commerce logistics transports goods to warehouses, they need to be unloaded. In small warehouses, workers usually push carts to unload goods. In large warehouses, there is usually a platform for trucks to dock at the door of the warehouse, and a liftable inclined unloading platform is installed on the edge of the platform. Workers place the goods directly on the unloading platform, and the goods slide along the platform to be unloaded.

[0003] For example, the invention application with publication number CN119527934A, in the technical field of logistics unloading platforms, specifically relates to an adjustable logistics unloading platform and its unloading method, including a fixed base, a lifting rod, a logistics platform, a transport mechanism, a connecting mechanism and a transition component; the fixed base is installed at the logistics unloading location; the lifting rod is installed on the top of the fixed base, and the lifting rod can be raised and lowered to adjust the height of the logistics platform, and the logistics platform is installed on the top of the lifting rod; the transport mechanism is installed obliquely on the side of the logistics platform, and the adjustment component inside the transport mechanism can adjust the length value of the exposed part of the connecting mechanism; the connecting mechanism is installed inside the adjacent transport mechanism, and the connecting mechanism fixes the two transport mechanisms together when they are pulled apart; the transition component is installed on the top of the connecting mechanism, and the transition component pops up when the connecting mechanism is pulled apart to continuously support the goods.

[0004] Combining the above cases with actual conditions, we found the following problems: When unloading goods on a loading platform, the goods usually slide directly down the inclined platform. When unloading goods at higher places, due to the high height, the platform needs a buffer device to slow down and prevent the goods from moving too fast. However, the buffer device is usually a rubber speed bump. When the goods pass through the buffer device, they are very likely to roll over or fall directly off the platform due to the hindrance of friction, causing damage to the goods. Summary of the Invention

[0005] The purpose of the present invention is to provide an e-commerce logistics unloading and inspection platform. By setting a first conveyor belt, a second conveyor belt and a supporting structure, the goods are transported by the inclined second conveyor belt. At the same time, under the action of the gravity of the goods themselves, the support plate is pushed to drive the telescopic plate to extend, and the fixed plate is lifted to prevent the center of gravity of the goods from being higher than the fixed plate and rolling out of the unloading platform, so as to solve the above-mentioned problems of the prior art.

[0006] To achieve the above-mentioned object, the present invention provides an e-commerce logistics unloading and inspection platform, comprising an unloading platform, wherein the unloading platform is provided with an unloading assembly for unloading and inspecting goods, wherein the unloading assembly comprises a horizontal first conveyor belt, an inclined second conveyor belt, and a plurality of supporting structures regularly arranged on the surface of the second conveyor belt;

[0007] The rear end of the first conveyor belt is hinged to the front end of the second conveyor belt, and the rear end of the second conveyor belt is slidably connected to the top surface of the unloading platform;

[0008] In this setting, the goods are conveyed from the first conveyor belt to the second conveyor belt, then fall onto the unloading platform and enter the logistics warehouse to complete unloading.

[0009] The supporting structure includes a fixed plate vertically fixed on the surface of the second conveyor belt, a supporting plate located in front of the fixed plate, and a push plate vertically arranged at the right end of the front side of the supporting plate, a connecting barrel is fixed symmetrically on the left and right sides of the rear side wall of the supporting plate, a push rod is provided in the fixed plate that is adapted to the position and size of the connecting barrel, a telescopic plate is provided in the fixed plate, an inclined portion is provided at the front side of the middle of the telescopic plate, the rear ends of the two connecting barrels are fixedly connected to the same connecting plate, two wedge blocks are fixed symmetrically on the rear side wall of the connecting plate, and the rear side wall of the wedge block is in contact with the front side wall of the inclined portion;

[0010] In this setting, by setting a pallet, when the goods enter the second conveyor belt, the pallet is pressed down by its own gravity, and the wedge block is driven to slide synchronously through the connecting plate, and the telescopic plate is pushed upward through the fixed plate through the inclined portion, thereby increasing the height of the supporting structure and preventing the goods from falling out of the second conveyor belt when tilted.

[0011] The side wall of the connecting barrel is connected to an air pipe near the front end, and the other end of the air pipe is sealed with the push plate;

[0012] In this setting, by setting a push plate, when the connecting barrel slides toward the fixed plate, the internal space of the connecting barrel is compressed, and the air inside the connecting barrel pushes the push plate to slide to the left along the air pipe, so that the overweight goods are located on the left side of the second conveyor belt, making it easier for subsequent staff to inspect the overweight goods.

[0013] In the technical solution of the present invention, a fixed seat is fixed symmetrically on the left and right sides of the top surface of the unloading platform near the front end, a bracket is slidably connected to the fixed seat, the first conveyor belt is fixed on the bracket, a hydraulic cylinder is fixed on the top surface of the unloading platform, and the output shaft of the hydraulic cylinder is fixed to the middle part of the bracket.

[0014] In this arrangement, a hydraulic cylinder is provided to drive the bracket and the first conveyor belt to slide up and down, thereby changing the height of the first conveyor belt so that the height of the first conveyor belt matches the height of the cargo in the truck, making it easier for workers to carry the cargo.

[0015] In the technical solution of the present invention, the second conveyor belt is tilted with the front higher and the rear lower, and the rear end of the second conveyor belt is symmetrically hinged with an articulated seat, and the top surface of the unloading platform is symmetrically provided with a slide groove near the rear end, and the articulated seat is slidably connected to the slide groove on the corresponding side.

[0016] In this configuration, the second conveyor belt is supported by providing an articulated seat, and the articulated seat is limited by providing a slide groove.

[0017] In the technical solution of the present invention, the rear end of the push rod is vertically fixed to the inner wall of the rear side of the fixed plate, the connecting barrel passes through the front side wall of the fixed plate, the connecting barrel and the fixed plate are slidingly connected, and the front end of the push rod is fixed with a piston that is adapted to the inner diameter of the connecting barrel, and a first spring is provided between the push rod and the corresponding rear side wall of the connecting barrel.

[0018] In this setting, when the cargo slides between the two supporting structures, it slides down under its own gravity and presses on the supporting plate, thereby driving the connecting barrel to slide synchronously and compressing the first spring, while compressing the space between the piston and the front side wall of the connecting barrel, and the first spring is set to drive the supporting plate to reset.

[0019] In the technical solution of the present invention, the top surface of the fixed plate is provided with an opening for the telescopic plate to move up and down, the inclined portion is generally in the shape of a wedge with a wide top and a narrow bottom, the wedge block is generally in the shape of a wedge with a narrow top and a wide bottom, and the rear inclined surface of the wedge block is in contact with the front inclined surface of the inclined portion.

[0020] In this setting, by setting the inclined portion and the wedge block, when the connecting barrel drives the connecting plate and the wedge block to slide, the rear side wall of the wedge block will apply a pressure perpendicular to the front side wall of the inclined portion. The component of this pressure in the vertical direction will push the telescopic plate to slide upward and extend out of the opening, thereby extending the fixed plate and preventing the goods from slipping.

[0021] In the technical solution of the present invention, telescopic holes are provided on the left and right sides of the telescopic plate, a sliding rod is slidably connected in the telescopic hole, the bottom end of the sliding rod is fixed to the bottom surface of the fixed plate, and a second spring is provided on the outer sleeve of the sliding rod.

[0022] In this setting, by setting a second spring, when the second spring is compressed and the goods are transported to the rear end of the second conveyor belt and unloaded, the restoring force of the second spring will pull the telescopic plate back into the fixed plate, preventing the telescopic plate from being unable to retract after being extended, causing it to collide with the first conveyor belt and block the movement of the second conveyor belt.

[0023] In the technical solution of the present invention, the support plate is symmetrically provided with horizontal limit grooves in the upper and lower parts, a limit rod is fixed between the left and right side walls of the limit groove, and blocks are symmetrically fixed on the rear side wall of the push plate in the upper and lower parts. The limit rod passes through the corresponding block and the two are slidably connected, and a return spring is provided on the limit rod to push the block to return to the right.

[0024] In this setting, the sliding of the push plate is limited by setting a block and a limit rod to prevent the push plate from separating from the support plate.

[0025] In the technical solution of the present invention, the left half of the trachea is a hard tube and the right half is a corrugated tube. The right end of the trachea passes through the right side wall of the limiting groove and is tightly connected to the right side wall of the block.

[0026] In this setting, when the internal space of the connecting barrel is compressed, the air inside the connecting barrel pushes the block along the air pipe, thereby driving the push plate to slide to the left.

[0027] In the technical solution of the present invention, the first conveyor belt is provided with a plurality of support plates for placing and supporting goods respectively. The support plates are vertically fixed on the first conveyor belt, and the distance between two adjacent support plates is adapted to the distance between two adjacent supporting structures.

[0028] In this setting, by setting the support plate spacing and the support structure spacing to match, the support plate can be close to the corresponding support structure each time, preventing goods from falling directly to the ground from the hinge of the first conveyor belt and the second conveyor belt.

[0029] In the technical solution of the present invention, a sponge pad for cushioning the falling of goods is provided on the top surface of the unloading platform between the two chutes.

[0030] This setting prevents the goods from sliding off the second conveyor belt and falling directly onto the unloading platform and being damaged.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. In the present invention, by providing a supporting structure, when unloading, the goods are transported to the upper inclined surface of the second conveyor belt. The goods slide down under the action of their own gravity and press down the supporting plate, so that the connecting barrel slides toward the fixed plate as the supporting plate slides, driving the wedge block to slide synchronously, and pushing the telescopic plate upward to pass through the fixed plate through the inclined portion, thereby increasing the height of the supporting structure, thereby preventing the center of gravity of the goods from being higher than the fixed plate due to the inclination of the second conveyor belt, causing the goods to roll out of the second conveyor belt and cause damage to the goods.

[0033] 2. In the present invention, by providing a push plate, when the connecting barrel slides toward the fixed plate, the internal space of the connecting barrel is compressed, and the air inside the connecting barrel pushes the block and the push plate to slide to the left along the air pipe. At the same time, the heavier the goods, the greater the distance the connecting barrel is pushed to slide, and the farther the push plate is pushed, so that the overweight goods are located on the left side of the second conveyor belt, which is convenient for subsequent staff to inspect the overweight goods.

DETAILED DESCRIPTION

[0049] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0050] Unless expressly stated otherwise, throughout the specification, the term “comprise” or variations thereof such as “include” or “comprising” will be understood to include the stated elements or components but not to exclude other elements or components.

[0051] Reference Figures 1-12 As shown, this embodiment provides a technical solution:

[0052] The e-commerce logistics unloading and inspection platform of the present invention includes an unloading platform 100, which is set on a platform for trucks to dock. The unloading platform 100 is provided with an unloading assembly 200 for unloading and inspecting goods. The unloading assembly 200 includes a horizontal first conveyor belt 201, an inclined second conveyor belt 202, and a plurality of supporting structures 210 regularly arranged on the surface of the second conveyor belt 202. The front end of the first conveyor belt 201 is flush with the truck compartment. Workers place goods on the first conveyor belt 201 and convey them to the second conveyor belt 202. After the goods fall onto the unloading platform 100, they enter the logistics warehouse to complete unloading.

[0053] The rear end of the first conveyor belt 201 is hinged to the front end of the second conveyor belt 202, and the rear end of the second conveyor belt 202 is slidably connected to the top surface of the unloading platform 100, ensuring that when the first conveyor belt 201 is adjusted in height, the second conveyor belt 202 can move along with it, thereby preventing the second conveyor belt 202 from blocking the height adjustment of the first conveyor belt 201, causing the entire device to be unable to adapt to changes in the height of the cargo in the truck and affecting unloading;

[0054] The supporting structure 210 includes a fixed plate 211 vertically bonded and fixed on the surface of the second conveyor belt 202, a supporting plate 212 located on the front side of the fixed plate 211, and a push plate 213 vertically arranged on the right end of the front side of the supporting plate 212. The rear side wall of the supporting plate 212 is symmetrically fixed with connecting barrels 214. The fixed plate 211 is provided with a push rod 216 that is adapted to the position and size of the connecting barrel 214. When the goods fall on the second conveyor belt 202, due to the inclined setting of the second conveyor belt 202, the goods slide down and press the supporting plate 212 under the action of their own gravity, causing it to slide toward the fixed plate 211 along the push rod 216. A telescopic plate 215 is provided in the fixed plate 211, and an inclined portion 215a is provided on the front side of the middle of the telescopic plate 215. The rear ends of the two connecting barrels 214 are fixedly connected to the same connecting plate 21 4a, two wedge blocks 214c are fixed symmetrically on the rear side wall of the connecting plate 214a, and the rear side wall of the wedge block 214c is in contact with the front side wall of the inclined portion 215a. When the connecting barrel 214 slides toward the fixed plate 211 along with the supporting plate 212, the wedge block 214c will be driven to slide synchronously through the connecting plate 214a, and the telescopic plate 215 will be pushed upward and out of the fixed plate 211 through the inclined portion 215a, thereby increasing the height of the supporting structure 210. In addition, the higher the first conveyor belt 201 is and the greater the inclination of the second conveyor belt 202 is, the greater the component of the gravity of the goods perpendicular to the supporting plate 212 is, so that the height of the supporting structure 210 is increased, thereby preventing the center of gravity of the goods from being higher than the fixed plate 211 due to the inclination of the second conveyor belt 202, causing the goods to roll out of the second conveyor belt 202 and causing damage to the goods.

[0055] An air pipe 218 is connected to the front end of the side wall of the connecting barrel 214, and the other end of the air pipe 218 is tightly connected to the push plate 213. The connecting barrel 214 and the air pipe 218 are filled with air. When the connecting barrel 214 slides toward the fixed plate 211, the internal space of the connecting barrel 214 is compressed, and the air inside the connecting barrel 214 pushes the push plate 213 to slide to the left along the air pipe 218. At the same time, the heavier the goods, the greater the distance the connecting barrel 214 is pushed to slide, and the farther the push plate 213 is pushed, so that the overweight goods are all located on the left side of the second conveyor belt 202, which is convenient for subsequent staff to inspect the overweight goods.

[0056] See also Figure 1-Figure 2As shown, a fixing seat 101 is welded and fixed symmetrically on the top surface of the unloading platform 100 near the front end, and a bracket 204 is slidably connected to the fixing seat 101. Guardrails are provided on the left and right sides of the first conveyor belt 201 and the second conveyor belt 202. The driving devices of the first conveyor belt 201 and the second conveyor belt 202 are both provided on the guardrails, which are not shown in the figure. This is the existing technology for conveyor belts and will not be described in detail here. A PLC controller for controlling the operation of the entire device is provided on the unloading platform 100. The specific control method is the existing technology and will not be described in detail here. As described above, the guardrails on both sides of the first conveyor belt 201 are welded and fixed to the bracket 204, and the hydraulic cylinder 203 is bolted to the top surface of the unloading platform 100. The output shaft of the hydraulic cylinder 203 is bolted to the middle part of the bracket 204. The hydraulic cylinder 203 drives the bracket 204 and the first conveyor belt 201 to slide up and down to change the height of the first conveyor belt 201, so that the height of the first conveyor belt 201 is adapted to the height of the goods in the truck, which is convenient for the staff to carry. It should be noted that the goods are placed on the right side of the first conveyor belt 201.

[0057] See also Figure 3-Figure 4 As shown, the second conveyor belt 202 is tilted with the front higher and the back lower, and the goods on the first conveyor belt 201 slide from the rear end onto the second conveyor belt 202. It should be noted that the height difference between the first conveyor belt 201 and the second conveyor belt 202 is small to avoid damage to the goods when they slide. The rear end of the second conveyor belt 202 is symmetrically hinged with an articulated seat 205, and the top surface of the unloading platform 100 is symmetrically provided with a slide groove 102 near the rear end. The articulated seat 205 is slidably connected to the corresponding side slide groove 102, and the articulated seat 205 is limited by setting the slide groove 102.

[0058] See also Figure 3-Figure 9 As shown, the rear end of the push rod 216 is fixed by a vertical bolt on the inner wall of the rear side of the fixed plate 211, the connecting barrel 214 passes through the front side wall of the fixed plate 211, the connecting barrel 214 and the fixed plate 211 are slidably connected, and a piston that is adapted to the inner diameter of the connecting barrel 214 is welded and fixed at the front end of the push rod 216. A first spring 214b is provided between the push rod 216 and the corresponding rear side wall of the connecting barrel 214. When the cargo slides between the two supporting structures 210, it slides down under the action of its own gravity and presses on the supporting plate 212, thereby driving the connecting barrel 214 to slide synchronously and compress the first spring 214b, and at the same time compressing the space between the piston and the front side wall of the connecting barrel 214.

[0059] See also Figure 10As shown, an opening is provided on the top surface of the fixed plate 211, and the opening is provided for the telescopic plate 215 to move up and down. The inclined portion 215a is in the shape of a wedge with a wide top and a narrow bottom as a whole, and the wedge block 214c is in the shape of a wedge with a narrow top and a wide bottom as a whole, and the rear inclined surface of the wedge block 214c is in contact with the front inclined surface of the inclined portion 215a. When the connecting barrel 214 drives the connecting plate 214a and the wedge block 214c to slide, the rear side wall of the wedge block 214c will apply a pressure perpendicular to the front side wall of the inclined portion 215a to the inclined portion 215a. The component of the pressure in the vertical direction will push the telescopic plate 215 to slide upward and extend out of the opening, thereby extending the fixed plate 211 and preventing the goods from slipping.

[0060] See also Figure 11 As shown, telescopic holes are provided on the left and right sides of the telescopic plate 215, and a slide bar 217 is slidably connected in the telescopic hole. The slide bar 217 is provided to limit the up and down sliding of the telescopic plate 215 to prevent the telescopic plate 215 from shaking and being unable to extend from the opening. The bottom end of the slide bar 217 is bolted to the bottom surface of the fixed plate 211, and a second spring 217a is provided on the outer sleeve of the slide bar 217. When the telescopic plate 215 slides upward, the second spring 217a is compressed. After the goods are transported to the rear end of the second conveyor belt 202 and unloaded, the restoring force of the second spring 217a will pull the telescopic plate 215 back into the fixed plate 211, avoiding the telescopic plate 215 from being unable to be retracted after being extended, causing it to collide with the first conveyor belt 201 and block the movement of the second conveyor belt 202.

[0061] See also Figure 6 and Figure 12 As shown, the support plate 212 is symmetrically provided with horizontal limit grooves 212a in the upper and lower parts, and a limit rod 212b is fixed between the left and right side walls of the limit groove 212a. The rear side wall of the push plate 213 is symmetrically fixed with a clamping block 213a in the upper and lower parts, and the limit rod 212b passes through the corresponding clamping block 213a and the two are slidably connected. By setting the clamping block 213a and the limit rod 212b, the sliding of the push plate 213 is limited to prevent the push plate 213 from separating from the support plate 212. A return spring 212c is provided on the limit rod 212b to push the clamping block 213a to return to the right.

[0062] Furthermore, the left half of the air pipe 218 is a hard tube and the right half is a bellows. The bellows is retractable to prevent the air pipe 218 from being unable to retract and shrink when the gas in the air pipe 218 is compressed to push the push plate 213, thereby affecting the movement of the push plate 213. The right end of the air pipe 218 passes through the right side wall of the limiting groove 212a and is tightly connected to the right side wall of the block 213a. When the internal space of the connecting barrel 214 is compressed, the air inside the connecting barrel 214 follows the air pipe 218 and pushes the block 213a, thereby driving the push plate 213 to slide to the left.

[0063] See also Figure 1As shown, the first conveyor belt 201 is provided with a plurality of support plates, which are used to place goods and support goods respectively. The support plates are vertically bonded and fixed to the first conveyor belt 201. When in use, the running speeds of the first conveyor belt 201 and the second conveyor belt 202 are adjusted so that the support plates and the fixed plates 211 are parallel and close to each other at the hinges of the first conveyor belt 201 and the second conveyor belt 202, so that the goods slide directly from the support plates to the fixed plates 211 under the action of their own gravity. At the same time, the distance between two adjacent support plates is adapted to the distance between two adjacent supporting structures 210, so that each support plate can be close to the corresponding supporting structure 210, avoiding that there is any goods falling directly to the ground from the hinges of the first conveyor belt 201 and the second conveyor belt 202. It should be noted that the surface of the second conveyor belt 202 is smooth, and the sliding friction between the second conveyor belt 202 and the goods is small, avoiding that the push plate 213 cannot push the goods.

[0064] In addition, a sponge pad is provided on the top surface of the unloading platform 100 between the two chutes 102 to cushion the falling of goods, thereby preventing the goods from sliding off the second conveyor belt 202 and falling directly onto the unloading platform 100 and being damaged.

[0065] The working principle of the e-commerce logistics unloading and inspection platform in the present invention is specifically as follows:

[0066] During unloading and inspection, the hydraulic cylinder 203 is activated to drive the first conveyor belt 201 to move up and down to adjust the height to match the height of the cargo in the truck. Then, the first conveyor belt 201 and the second conveyor belt 202 are activated and their running speeds are adjusted to match.

[0067] After the adjustment is completed, the staff on the truck places the goods between the support plates of the first conveyor belt 201 on the right side. As the first conveyor belt 201 runs, the goods are transported to the rear end of the first conveyor belt 201 and fall on the supporting structure 210 at the front end of the second conveyor belt 202 under the action of its own gravity. As the second conveyor belt 202 runs, the goods are transported to the upper inclined surface of the second conveyor belt 202. At this time, under the action of its own gravity, the goods slide down and press down the supporting plate 212, so that the connecting barrel 214 slides toward the fixed plate 211 with the supporting plate 212, driving the wedge block 214c to slide synchronously, and through The inclined portion 215a pushes the telescopic plate 215 upward to pass through the fixed plate 211, thereby increasing the height of the supporting structure 210. Moreover, the higher the first conveyor belt 201 is and the greater the inclination of the second conveyor belt 202 is, the greater the component of the weight of the goods perpendicular to the supporting plate 212 is, so that the height of the supporting structure 210 is increased. This prevents the center of gravity of the goods from being higher than the fixed plate 211 due to the inclination of the second conveyor belt 202, causing the goods to roll out of the second conveyor belt 202 and cause damage to the goods. As the second conveyor belt 202 runs, the goods are transported to the bottom end of the second conveyor belt 202 and slide off, completing unloading.

[0068] At the same time, when the connecting barrel 214 slides toward the fixed plate 211, the internal space of the connecting barrel 214 is compressed, and the air inside the connecting barrel 214 pushes the block 213a and the push plate 213 to slide to the left along the air pipe 218. At the same time, the heavier the goods, the greater the distance the connecting barrel 214 is pushed to slide, and the farther the push plate 213 is pushed, so that the overweight goods are located on the left side of the second conveyor belt 202, which is convenient for subsequent staff to inspect the overweight goods.

[0069] The foregoing descriptions of specific exemplary embodiments of the present invention are for purposes of illustration and description. These descriptions are not intended to limit the invention to the precise forms disclosed, and it is apparent that many variations and modifications are possible in light of the foregoing teachings. The exemplary embodiments have been selected and described for the purpose of explaining the specific principles of the invention and their practical application, thereby enabling those skilled in the art to make and utilize a variety of exemplary embodiments of the invention and various options and modifications. The scope of the invention is intended to be defined by the description and its equivalents.
