Description

Technical Field

[0001] This invention relates to the field of cargo sorting equipment technology, specifically to an automated cargo sorting device and method for transportation. Background Technology

[0002] Goods are a general term for items, covering a wide range, including production supplies, items, clothing, and industrial workpieces on factory assembly lines. These goods undergo quality inspection or random checks before leaving the factory to improve the overall production quality.

[0003] Existing cargo sorting methods typically involve observation or weighing to separate goods of different weights or shapes. Once different types of goods are sorted, they can be processed in different ways. However, existing technologies require additional equipment for conversion when implementing weighing and sorting. In some manufacturing and packaging processes, goods are often divided into several types, such as fruit boxes containing apples and oranges, each with a different weight. Existing technologies weigh each box before sorting, which significantly reduces transportation efficiency and increases equipment and labor costs. Therefore, an automated cargo sorting device and method for transportation is proposed to address these issues. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an automated sorting device and method for transporting goods, which solves the problem that existing technologies cannot achieve automatic weighing and sorting during the automatic conveying process, resulting in excessive time spent on sorting and weighing of goods, thus affecting the efficiency of goods delivery.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automated cargo sorting device for transportation, comprising a control unit; a frame; a conveyor for conveying cargo; a sorting mechanism for automatically sorting cargo according to its weight; and an intermittent mechanism for controlling the equidistant discharge of cargo on the conveyor. The sorting mechanism includes a weighing component and a transposition component. The weighing component includes a guide plate, a pressure rod connected to the bottom of the guide plate, a fixed plate slidably connected to the bottom of the pressure rod, the fixed plate being fixed to the frame, a compression spring sleeved on the surface of the pressure rod, the bottom of the compression spring being connected to the fixed plate, and the top of the compression spring being connected to the pressure rod. Cargo, after being conveyed by the conveyor, will fall onto the weighing component for automatic weighing. The weighing component and the transposition component are connected by a transmission mechanism.

[0008] Preferably, the shifting component includes a fixed sleeve mounted on the frame, a rotating sleeve rotatably connected inside the fixed sleeve, a central gear connected to the axis of the rotating sleeve via a connecting rod, a lower rack meshing with the surface of the central gear, and the top of the lower rack fixedly connected to the guide plate.

[0009] Preferably, the lower surface of the fixed sleeve is provided with multiple diversion ports, and the rotating sleeve is provided with multiple guide ports. The diversion ports and guide ports are matched with each other, and the depth and length of the multiple guide ports are different.

[0010] Preferably, the flow guide and the flow guide plate are inclined, a photoelectric sensor is installed on one side of the flow guide plate, a cylinder is installed on the other side of the flow guide plate, a flow channel is provided on the flow guide plate, and the photoelectric sensor is electrically connected to the cylinder.

[0011] Preferably, the conveying component includes a driving component and a rolling component. The driving component includes a motor, the output end of which is connected to the rolling component via a belt. The rolling component includes two conveying rollers, and the surfaces of the two conveying rollers are connected via a conveyor belt. Two cams are connected to the central shaft of one of the conveying rollers, and the surface of the cams abuts against a push plate. The push plate is connected to an intermittent mechanism.

[0012] Preferably, the intermittent mechanism includes a fixed block, which is fixed to a fixed sleeve. A support rod is slidably connected inside the fixed block. The support rod is connected to a push plate. A return spring is sleeved on the surface of the support rod. One end of the return spring is connected to the support rod, and the other end of the return spring is connected to the fixed block. A tripod is connected to the support rod, and the tripod is connected to a limiting member.

[0013] Preferably, the limiting component includes two rotating plates, both of which are symmetrically arranged on the frame. Sliding pins are connected to the two rotating plates. A sliding groove is provided on the tripod, and the sliding pins are slidably connected inside the sliding groove.

[0014] Preferably, the push plate has two slide rods connected to its side, and the two slide rods are slidably connected to the frame, with the center lines of the two slide rods being horizontal to the center lines of the two cams respectively.

[0015] An automated sorting method for transport goods includes the following steps:

[0016] Step 1: Delivery and Conveying. The packaged goods are placed on a conveyor belt using a robot or external device, and the conveyor belt transports the goods.

[0017] Step 2: Equidistant control, using an intermittent mechanism to distribute goods on the conveyor at equal intervals;

[0018] Step 3: Automatic weighing. The conveyor transports the goods to the guide plate, and then the weighing device automatically weighs the goods and controls the rotation and repositioning of the shifting device according to the distance of the downward displacement due to gravity.

[0019] Step 4: Alignment and conveying. The transposition component rotates at different angles according to the different weights of the goods, thereby controlling the guide ports at different angles to rotate directly upwards, and the goods will slide into the interior of the guide ports according to the inclined plane setting.

[0020] Step 5: Reset Conveying. After the goods on the guide plate enter the guide port, there is no gravity pressing on the guide plate. It will be controlled by the elastic force of multiple compression springs to move the guide plate upward and reset. At the same time, through the meshing rotation of gears, the rotation of the rotating sleeve will also be controlled to reset. In turn, the rotation of the rotating sleeve is used to control the internal goods of the guide port to be moved and put out.

[0021] Step Six: Abnormal Repositioning. When the weight of the descending guide plate does not match multiple guide ports, the cargo will be blocked on the guide plate by the misalignment angle of the rotating sleeve. The photoelectric sensor senses the cargo through laser light. If the cargo on the guide plate remains for a long time, it will trigger the photoelectric sensor to generate an action electrical signal. The electrical signal will be transmitted to the cylinder, and the extension of the cylinder will push the cargo on the guide plate to the position of the flow channel for it to slide down.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the present invention provides an automated sorting device and method for transporting goods, which has the following beneficial effects:

[0024] 1. The automated cargo sorting device and method for transportation can achieve automatic weighing of cargo after automatic conveying through the set sorting mechanism. The rotation angle of the transducer is controlled according to the sinking distance of different gravity, and the cargo is finally automatically guided to different channels for release. This realizes automatic sorting of cargo with automatic load and final automatic delivery. The whole system adopts an integrated equipment flow operation, thereby reducing the input of manpower and redundant equipment, reducing costs, and improving the overall cargo sorting and conveying efficiency.

[0025] 2. The automated sorting device and method for transporting goods can control the goods on the conveyor at equal intervals through the set intermittent structure, avoiding the compression of goods during transport, which would lead to the stacking of multiple goods in the subsequent weighing, thereby providing operating space and time for subsequent weighing and repositioning, and improving the smoothness of equipment operation.

[0026] 3. The automated sorting device and method for transporting goods, through the linkage of photoelectric sensors and electrical signals of cylinders, can push abnormally weighed goods on the guide plate into another collection channel, which facilitates subsequent inspection of abnormal goods by operators and prevents abnormal goods from entering the conveyor line.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figures 1-8 An automated cargo sorting device for transportation includes a control unit 1; a frame 5; a conveyor 2 for conveying cargo; a sorting mechanism 3 for automatically sorting cargo according to its weight; and an intermittent mechanism 4 for controlling the equidistant discharge of cargo on the conveyor 2. The sorting mechanism 3 includes a weighing component and a transposition component.

[0039] In this embodiment, the weighing component includes a guide plate 303. The guide plate 303 not only serves as a receiving surface for goods transitioning from the conveyor 2 to the weighing position, but also functions as a gravity sensing and transmission device. The bottom of the guide plate 303 is connected to the fixed structure below via multiple pressure rods 304. Each pressure rod 304 passes through a horizontally set fixed plate 306. The fixed plate 306 is firmly installed on the frame 5 by bolts or welding to ensure the stability of the overall structure. The bottom of the guide plate 303 is connected to the pressure rod 304, and the bottom of the pressure rod 304 is slidably connected to the fixed plate 306. The fixed plate 306 is fixed on the frame 5. A compression spring 305 is sleeved on the surface of the pressure rod 304. The bottom of the compression spring 305 is connected to the fixed plate 306, and the top of the compression spring 305 is connected to the pressure rod 304. After being conveyed by the conveyor 2, the goods will fall onto the weighing component to achieve automatic weighing. The weighing component is connected to the shifting component via a transmission. The weighing and shifting components are linked via mechanical transmission. Specifically, the downward movement of the guide plate 303 causes the lower rack 308, which is fixed to it, to move downward. The lower rack 308 meshes with the central gear 307, thereby driving the rotating sleeve 302 to rotate. Through this structure, the weight information of the goods is converted into the rotation angle of the rotating sleeve 302, thus realizing the function of automatically selecting the corresponding outlet channel according to different weights.

[0040] Furthermore, the shifting component includes a fixed sleeve 301, which is mounted on the frame 5. A rotating sleeve 302 is rotatably connected inside the fixed sleeve 301. A central gear 307 is connected to the axis of the rotating sleeve 302 via a connecting rod. A lower rack 308 meshes with the surface of the central gear 307, and the top of the lower rack 308 is fixedly connected to the guide plate 303. When cargo falls onto the guide plate 303, its weight forces the guide plate 303 to move downwards against the resistance of the compression spring 305. This downward linear motion is transmitted to the meshing central gear 307 via the lower rack 308. The downward movement of the lower rack 308 drives the central gear 307 to rotate, and the rotation of the central gear 307 directly drives the rotating sleeve 302 to rotate by a specific angle inside the fixed sleeve 301 via the connecting rod. The displacement of the guide plate 303 due to the different weight of the cargo is linear, and this linear displacement is precisely converted into the angular displacement of the rotating sleeve 302 through the gear-rack pair. Therefore, different cargo weights ultimately correspond to different stopping angles of the rotating sleeve 302, thus preparing for the subsequent switching of the aligned guide port 310 to the cargo outlet position.

[0041] Furthermore, the lower surface of the fixed sleeve 301 has multiple diversion ports 309, and the rotating sleeve 302 has multiple guide ports 310. The diversion ports 309 and guide ports 310 are matched with each other, and the depths and lengths of the multiple guide ports 310 are different. The depth of the guide port 310 determines the height position of its inlet on the cylinder wall of the rotating sleeve 302. The deeper guide port 310 has a lower inlet position; the shallower guide port 310 has a higher inlet position. This is directly related to the downward displacement of the guide plate 303 during weighing. Only when the corresponding weight is reached can the guide plate 303 sink to a sufficiently low position, allowing the goods to smoothly slide into the guide port 310 of a specific depth that matches the inlet position. If the weight is too light or too heavy, it will not enter the wrong channel, thus realizing a weight-based mechanical screening. The length of the guide port 310 affects the phase of its outlet in the circumferential direction. The outlet ends of the guide ports 310 of different lengths will align with their respective unique diversion ports 309 at different circumferential positions when the rotating sleeve 302 is reset and rotated. This ensures that even if the rotating sleeve 302 rotates uniformly during reset, the goods in the different guide ports 310 inside can be accurately "placed" into their respective predetermined and different diversion ports 309, realizing multi-path parallel sorting under a single rotation action.

[0042] In addition, the guide port 310 and the guide plate 303 are inclined. A photoelectric sensor 411 is installed on one side of the guide plate 303, and a cylinder 410 is installed on the other side. A flow channel 412 is provided on the guide plate 303. The photoelectric sensor 411 is electrically connected to the cylinder 410. The inclined arrangement ensures that the goods can generate a component force along the inclined plane under their own weight, so that they can slide automatically and smoothly without additional positive pushing power. The inclination of the guide plate 303 facilitates the smooth transition of goods from the conveyor and accelerates their slide to the weighing position; while the inclination of the guide port 310 ensures that the sorted goods can slide smoothly into the channel. A photoelectric sensor 411 is installed on one side of the guide plate 303, usually at the end or side of the goods sliding path. This sensor forms an invisible detection light curtain by emitting and receiving laser or infrared light. When goods remain on the guide plate 303, they will block the light. If cargo becomes stuck in the flow channel 310 due to abnormal weight and cannot be matched with any of the flow channels 310, the sensor will continuously detect the obstruction signal. On the opposite side of the flow channel 303, opposite the photoelectric sensor 411, a cylinder 410 is installed. The photoelectric sensor 411 and the cylinder 410 are electrically connected via wiring, forming a simple automatic control loop. When the photoelectric sensor 411 detects that the abnormal cargo has been stuck for more than a preset time, as determined by the timing logic within the controller, it immediately sends an action signal to the cylinder 410. When an "abnormal cargo" with an incorrect weight appears, it cannot cause the flow channel 303 to sink to a position matching any of the flow channels 310, and therefore will stop on the flow channel 303. After continuously detecting this stuck state, the photoelectric sensor 411 triggers a signal. Upon receiving the signal, the cylinder 410 quickly moves, its push rod extending forward, like a "mechanical arm," precisely pushing the stuck cargo laterally away from its original position, allowing it to enter the preset flow channel 412. The goods then slide down this dedicated flow channel 412 and are collected for subsequent manual inspection and processing.

[0043] It is worth noting that the conveyor component 2 includes a driving component and a rolling component. The driving component includes a motor, the output of which is connected to the rolling component via a belt. The rolling component includes two conveyor rollers, the surfaces of which are connected by a conveyor belt. Two cams 408 are connected to the central shaft of one of the conveyor rollers, and the surfaces of the cams 408 abut against a push plate 409, which is connected to the intermittent mechanism 4. The motor is typically an adjustable speed motor to adjust the conveying speed according to the actual production cycle. The rotational power of the motor is transmitted through a belt drive mechanism. This transmission method has the advantages of buffering, shock absorption, and overload protection, while allowing for flexible layout between the motor and the conveyor rollers. The rolling component includes two parallel conveyor rollers, which are supported on the frame 5 by bearings. A conveyor belt is fitted and tensioned on the surfaces of these two conveyor rollers, thus forming a complete closed-loop conveying circuit. When the motor drives one of the conveyor rollers to rotate via the belt, friction causes the conveyor belt and the goods on it to move forward together.

[0044] It is worth mentioning that the intermittent mechanism 4 includes a fixed block 402, which is fixed to the fixed sleeve 301. A support rod 401 is slidably connected inside the fixed block 402. The support rod 401 is connected to the push plate 409. A return spring 403 is sleeved on the surface of the support rod 401. One end of the return spring 403 is connected to the support rod 401, and the other end is connected to the fixed block 402. A tripod 404 is connected to the support rod 401 and is connected to a limiting member. One end of the support rod 401 is directly connected to the push plate 409 from the conveyor 2 to receive the periodic thrust generated by the cam 408. A return spring 403 is sleeved on the surface of the support rod 401. One end of the spring acts on a structure of the support rod 401, such as a shoulder or retaining ring, while the other end rests against the fixed block 402. When the protruding part of the cam 408 pushes the push plate 409 and the support rod 401 to one side, for example, to the right, the return spring 403 is compressed and stores elastic potential energy. When the cam 408 rotates past the protruding part, the pushing force on the push plate 409 disappears. At this time, the potential energy stored in the return spring 403 is quickly released, driving the support rod 401 and the push plate 409 to slide in the opposite direction to the left until they return to the initial position, completing one working cycle.

[0045] In addition, the limiting component includes two rotating plates 406, which are symmetrically arranged on the frame 5. Sliding pins 407 are connected to the two rotating plates 406. A sliding groove 405 is provided on the tripod 404, and the sliding pins 407 are slidably connected inside the sliding groove 405. The conveyor roller rotates → the cam 408 rotates to generate thrust → the push plate 409 is subjected to force → the support rod 401 slides to the right against the elastic force of the return spring 403 → the tripod 404 moves accordingly → through the cooperation of the sliding groove 405 and the sliding pins 407, the linear motion is converted into the opening action of the rotating plate 406 to release one item → the protruding part of the cam 408 rotates → the return spring 403 pushes the support rod 401 to return to the left → the tripod 404 moves in the opposite direction → the rotating plate 406 retracts to prepare to block the next item. Two sliding rods are connected to the side of the push plate 409, and these two sliding rods are slidably connected to the frame 5. The center lines of the two sliding rods are horizontal with the center lines of the two cams 408 respectively. By using two sliding rods, the push plate 409 can be limited to axial displacement when it is pushed by the cam 408, thereby improving the running stability of the push plate 409.

[0046] Example 2

[0047] An automated sorting method for transport goods includes the following steps:

[0048] Step 1: Delivery and Conveying. The packaged goods are placed on conveyor 2 using a robot or external device, and then conveyed by conveyor 2.

[0049] Step 2: Equidistant control, using intermittent mechanism 4 to discharge goods on conveyor 2 at equal intervals;

[0050] Step 3: Automatic weighing. Conveyor 2 transports the goods to guide plate 303. Then, the weighing device automatically weighs the goods and controls the rotation and repositioning of the shifting device according to the distance of gravity downward movement.

[0051] Step 4: Alignment and conveying. The transposition component rotates at different angles according to the different weights of the goods, thereby controlling the guide ports 310 at different angles to rotate directly upwards, and the goods will slide into the interior of the guide ports 310 according to the inclined plane setting.

[0052] Step 5: Reset Conveying. After the goods on the guide plate 303 enter the guide port 310, there is no gravity pressing on the guide plate 303. It will be controlled by the elastic force of multiple compression springs 305 to move the guide plate 303 upward and reset. At the same time, through the meshing rotation of gears, the rotation of the rotating sleeve 302 will also be controlled to reset. Then, the rotation of the rotating sleeve 302 will be used to control the internal goods of the guide port 310 to be moved and put out.

[0053] Step Six: Abnormal Relocation. When the weight of the descending guide plate 303 does not match the multiple guide ports 310, the goods will be blocked on the guide plate 303 by the misalignment angle of the rotating sleeve 302. The photoelectric sensor 411 will generate an action electrical signal when the goods on the guide plate 303 have been present for a long time, and the electrical signal will be transmitted to the cylinder 410. The extension of the cylinder 410 will push the goods on the guide plate 303 to the position of the flow channel 412 and slide down.

[0054] The working principle is as follows: First, the conveyor component 2 needs to be started. The rotation of the motor drives the pulley, which in turn drives the two conveyor rollers to rotate. The conveyor belt slowly transports the goods placed on it. During the transport process, two rotating plates 406 provide centering guidance, ensuring that round packaging boxes are positioned in the middle of the conveyor belt. Each rotation of the conveyor rollers drives the cam 408 to rotate. Each rotation of the cam 408 controls the position of the protrusion to press against the push plate 409, thereby controlling the push plate 409. When cam 408 moves to the right, push plate 409 drives support rod 401 to move synchronously. Support rod 401 then compresses return spring 403, synchronously driving tripod 404 to move to the right. As tripod 404 moves, it causes sliding pin 407 located in slide groove 405 to expand. This expansion, in turn, causes two rotating plates 406 to rotate relative to each other, opening them a certain distance apart. Goods then pass through this opening and are conveyed by the conveyor belt into the weighing position, i.e., the guide plate 303. Therefore, the rotation of cam 408 indirectly controls the opening and closing of the two rotating plates 406, releasing the goods and ultimately achieving intermittent, equidistant discharge. After the guide plate 303 bears a certain weight of goods, it will sink, compressing the compression spring 305. Then, the sinking of the guide plate 303 will drive the lower rack 308 to move downward. The meshing of the gear and rack will drive the rotating sleeve 302 to rotate. The sinking distance of the guide plate 303 is converted into the rotation angle of the rotating sleeve 302, which in turn controls the guide port 310 on the rotating sleeve 302 to rotate to the top. At this time, the goods will enter the interior of the guide port 310 along the slope. After the guide plate 303 is free of goods, the compression spring 305 will reset and control the upward movement of the guide plate 303. Then, the reset of the gear and rack will control the reset rotation of the rotating sleeve 302 to rotate to the corresponding diversion port 309 position to realize the delivery. To prevent goods from falling from the other diversion ports 309, guide ports 310 of different depths and lengths are provided. When goods enter the guide ports 310, they enter guide ports 310 of different depths. During the rotation of the rotating sleeve 302, goods at different depths will be blocked by the stepped positions of the diversion ports 309 on the fixed sleeve 301. Only when the diversion ports 309 and the corresponding guide ports 310 cooperate will there be no step. Figure 6When the guide port 310 corresponds to different diversion ports 309, the internal steps will prevent goods from falling, avoiding single placement of sorted goods. Different depths and lengths are used to limit the placement position of the goods. Because different goods have different weights, if the depth of the guide port 310 is the same, when the guide plate 303 sinks, the goods will be blocked on the side of the rotating sleeve 302 and cannot enter the interior of the guide port 310. Of course, during packaging and transportation, there will inevitably be defective or abnormal items. If the weight of the goods is not corresponding, the rotating sleeve 302 will not rotate at the corresponding angle according to gravity, thus blocking between the rotating sleeve 302 and the guide plate 303. When the light emitted by the photoelectric sensor 411 shines on the goods for a certain period of time, an electrical signal will be generated to control the extension of the cylinder 410. The extension of the cylinder 410 will then push the goods into the flow channel 412, and the goods will flow to another abnormal collection position, facilitating subsequent inspection by operators to check for empty boxes, missing items, or extra items.

One end of the return spring (403) is connected to the support rod (401), and the other end of the return spring (403) is connected to the fixed block (402). A tripod (404) is connected to the support rod (401), and the tripod (404) is connected to a limiting member.

4. The automated cargo sorting device for transportation according to claim 3, characterized in that: The limiting component includes two rotating plates (406), which are symmetrically arranged on the frame (5). Sliding pins (407) are connected to the two rotating plates (406). A sliding groove (405) is provided on the tripod (404), and the sliding pin (407) is slidably connected inside the sliding groove (405).

5. The automated cargo sorting device for transportation according to claim 4, characterized in that: The push plate (409) has two slide rods connected to its side, and the two slide rods are slidably connected to the frame (5). The center lines of the two slide rods are horizontal to the center lines of the two cams (408).

6. An automated sorting method for transport goods, characterized in that: The automated cargo sorting device for transportation as described in claim 5 further includes the following steps: Step 1: Delivery and transport. The packaged goods are placed on the conveyor (2) by a robot or external device, and the goods are transported by the conveyor (2). Step 2: Equidistant control, using intermittent mechanism (4) to discharge goods on conveyor (2) at equal intervals; Step 3: Automatic weighing. The conveyor (2) conveys the goods to the guide plate (303). Then, the weighing device automatically weighs the goods and controls the rotation and repositioning of the shifting device according to the distance of gravity downward movement. Step 4: Alignment and conveying. The transposition component rotates at different angles according to the different weights of the goods, thereby controlling the guide ports (310) at different angles to rotate to the top. The goods will slide into the interior of the guide ports (310) according to the setting of the inclined plane. Step 5: Reset Conveying. After the goods on the guide plate (303) enter the guide port (310), there is no gravity pressing on the guide plate (303). It will be controlled by the elastic force of multiple compression springs (305) to move the guide plate (303) upward and reset. At the same time, through the meshing rotation of the gear, it will also control the rotation reset of the rotating sleeve (302). Then, by using the rotation reset of the rotating sleeve (302), the internal goods of the guide port (310) are shifted and put into place. Step Six: Abnormal Relocation. When the weight of the descending guide plate (303) does not match the multiple guide ports (310), the goods will be blocked on the guide plate (303) by the misalignment angle of the rotating sleeve (302). The photoelectric sensor (411) will generate an action electrical signal when the goods on the guide plate (303) are present for a long time through laser light sensing. The electrical signal will be transmitted to the cylinder (410). The extension of the cylinder (410) will push the goods on the guide plate (303) to the position of the flow channel (412) and slide down.
