[0021] See also Figure 1-12 The present invention provides a technical solution: an automatic loading and unloading and sorting system for bulk commodities, comprising a loading and unloading component and a sorting and transporting path. The loading and unloading assembly includes a transport part 4, a height-appropriate conveyor belt 1 and a transition belt 2; The transporting part 4 includes a pair of flipping arms 401, which are used to clamp the goods and flip them onto the conveyor belt 1 at a suitable height. The inner side of the head end of the flipping arm 401 is rotatably connected to a balancing plate 402, and a counterweight block is arranged on the inner lower side of the balancing plate 402; The suitable height conveyor belt 1 includes a base 9, a plurality of thin and narrow belts 101, an active transmission cylinder 102 and a driven transmission cylinder 1 103, the two ends of the plurality of thin and narrow belts 101 are sleeved and tensioned on the active transmission cylinder 102 and the driven transmission cylinder 1 103, and the transition belt 2 similarly includes a plurality of thin and narrow short belts and a driven transmission cylinder 2 104, the plurality of thin and narrow short belts are sleeved and tensioned on the active transmission cylinder 102 and the driven transmission cylinder 2 104, and the plurality of thin and narrow short belts are staggered with the thin and narrow belts 101; A pair of strip brackets 105 are provided at both ends of the active transmission cylinder 102 and the driven transmission cylinder 103, the base 9 is provided at the lower side of the appropriate height conveyor belt 1, and a pair of power chambers 106 are provided at one end of the base 9, and the power chambers 106 are correspondingly provided at both ends of the active transmission cylinder 102, and the power chambers 106 are used to drive the strip brackets 105 to be lifted with the active transmission cylinder 102 as the axis; The sorting and transporting lane includes a main channel 5, which is connected to the transition zone 2. A diverter platform 6 is provided at the end of the main channel 5. An infrared scanning camera 601 is provided at the upper end of the diverter platform 6. The first diverter channel 501, the second diverter channel 502 and the third diverter channel 503 are respectively provided on the outer side of the diverter platform 6. The infrared scanning camera 601 scans and identifies the barcode of the goods, and sorts the goods transported in the main channel 5 to the first diverter channel 501, the second diverter channel 502 or the third diverter channel 503 through the diverter platform 6.

[0022] First, the strip bracket 105 is driven by a pair of power chambers 106, so that the suitable height conveyor belt 1 rotates with the active transmission cylinder 102 as the axis, thereby lifting the other end thereof, so that it is convenient to extend to unloading trucks at different heights for loading and unloading of goods, and it has strong versatility. Then, the goods can be transported by the transporting part 4. Specifically, a pair of flipping arms 401 drives a pair of balancing plates 402 to move relative to each other, clamps the goods, and then the flipping arms 401 flip it onto the suitable height conveyor belt 1. Preferably, in order to prevent the flipping arms 401 from causing the goods to flip themselves during the flipping process, a balancing plate 402 is provided. and a counterweight block. Specifically, since the counterweight block is arranged at the lower side of the balancing plate 402, the balancing plate 402 always keeps its center of gravity downward during the flipping process. Therefore, the balancing plate 402 can be flipped almost in a relatively static state during the flipping process. When the balancing plate 402 is clamped at the middle side of the goods, the center of gravity of the goods is also vertically downward and balanced. Since the state of the balancing plate 402 remains unchanged (i.e., the center of gravity is always downward), it can remain relatively stable when the clamped goods are flipped until the goods are placed on the upper side of the conveyor belt 1 at an appropriate height, and the handling work can be completed without manual handling, saving time and effort. Then, the active transmission cylinder 102 rotates to drive several narrow belts 101 to transport the goods. Preferably, since the inclination angle of the height-appropriate conveyor belt 1 can be adjusted according to different loading and unloading scenarios, a transition belt 2 is provided to achieve seamless transition transportation of goods. Similarly, several narrow short belts are provided to be staggered with the narrow belts 101 to achieve seamless handover of goods and ensure the stability of transportation. Then the transition belt 2 transports the goods to the main channel 5, and the main channel 5 immediately transfers the goods to the diversion platform 6, and the barcode on the goods bill is scanned and identified by the equipped infrared scanning camera 601. Then the control system enables the diversion platform 6 to sort the goods to the first diversion channel 501, the second diversion channel 502 or the third diversion channel 503 according to the identification result, and the sorting work is completed.

[0023] A limited bracket rod 201 is arranged on the outer side of the strip bracket 105, and the lower end of the limited bracket rod 201 is hingedly connected to a sliding seat 202. A pair of convex grooves 203 are provided on the upper side of the base 9, and the sliding seat 202 slides along the convex grooves 203. An adaptation groove is provided on the outer side of the strip bracket 105, and the adaptation groove is adapted to the limited bracket rod 201.

[0024] Preferably, in order to ensure the stability of the height conveyor belt 1 when it is lifted and transporting goods, and to further share the load of the power chamber 106, a limiting bracket rod 201 is provided. Specifically, when the height conveyor belt 1 is lifted, the limiting bracket rod 201 is pulled to make the sliding seat 202 move along the convex groove 203. When the height conveyor belt 1 is adjusted, the friction between the sliding seat 202 and the convex groove 203 limits the position of the sliding seat 202 itself, so that the limiting bracket rod 201 further supports the strip bracket 105, thereby improving stability.

[0025] The lower end of the base 9 is fixedly connected to a convex support 901, and a square opening is provided at the bottom of the convex groove 203, in which a beveled tooth clamping plate 204 is slidably fitted, and a plurality of vertical rods 205 are fixedly connected to the lower end of the beveled tooth clamping plate 204, and a baffle is fixedly connected to the lower end of the vertical rod 205, and a circular groove is provided on the inner side of the convex support 901, in which the baffle slides, and a spring member is sleeved on the outer side of the vertical rod 205, and a plurality of oblique teeth are clamped on the upper end of the beveled tooth clamping plate 204, and the oblique teeth are fixedly connected to the sliding seat 202.

[0026] In the above embodiment, the stability of limiting the sliding seat 202 by friction force is poor. Preferably, a beveled tooth clamping plate 204 is provided. Under the action of the spring member, when the beveled tooth clamping plate 204 is in the uppermost position, it engages with the beveled teeth. When one end of the suitable height conveyor belt 1 is lifted, the beveled teeth of the sliding seat 202 are pulled to slide correspondingly to the inclined surface of the beveled tooth clamping plate 204, and the beveled tooth clamping plate 204 moves downward until the adjustment of the suitable height conveyor belt 1 is completed. The beveled teeth and the beveled tooth clamping plate 204 engage with each other, and the position of the sliding seat 202 can be locked, thereby stably supporting the strip bracket 105.

[0027] A driving rod 111 is rotatably connected between the pair of power chambers 106. The driving rod 111 penetrates the active transmission cylinder 102 and is fixedly connected thereto. The driving rod 111 is driven to rotate by the motor assembly. A clamping disc 107 is disposed at one end of the strip bracket 105 , and both ends of the driving rod 111 pass through the clamping disc 107 and are rotatably connected thereto. The clamping disc 107 is used to drive the strip bracket 105 to rotate around the driving rod 111 as an axis.

[0028] Preferably, the strip bracket 105 is driven to rotate by the clamping plate 107, so that one end of the height-appropriate conveyor belt 1 can be driven to be lifted and adjusted; Preferably, the driving rod 111 is driven to rotate by a motor assembly, thereby driving the active transmission cylinder 102 to rotate, thereby driving the narrow belt 101 to transport goods.

[0029] The clamping disk 107 is rotatably connected to the strip bracket 105, and a clamping mechanism is provided on the inner side of the strip bracket 105, which is used to clamp the clamping disk 107. A fixed disk 108 is provided on the inner side of the power chamber 106, and one end of the fixed disk 108 is fixedly connected to a plurality of connecting rods 109, and the connecting rods 109 are fixedly connected to the clamping disk 107. A movable disk 110 is provided between the fixed disk 108 and the clamping disk 107, and the connecting rod 109 passes through the movable disk 110 and slides with it. The surfaces of both ends of the driving rod 111 are provided with bidirectional external threads, and both ends of the driving rod 111 pass through the movable disk 110 and are threadedly connected with it.

[0030] Preferably, a clamping mechanism is provided so that the clamping plate 107 and the strip bracket 105 are locked with each other. Specifically, when the two are locked with each other, the driving rod 111 is rotated (the rotation direction is as shown in FIG. Figure 4 When the lifting and lowering of the movable plate 108 are completed, the movable plate 110 is moved in the direction of the fixed plate 108 until the two are in contact. At this time, the movable plate 110 cannot continue to move, and the driving rod 111 continues to rotate. When the driving force is greater than the gravity of the suitable height conveyor belt 1, one end of the suitable height conveyor belt 1 can be lifted to the required position, and then the limiting bracket rod 201 is used to support and limit the suitable height conveyor belt 1. After the suitable height conveyor belt 1 is stabilized, the locking mechanism can release the locking of the locking plate 107, so that the locking plate 107 can rotate relative to the strip bracket 105. At this time, the driving rod 111 continues to rotate, which can drive the active transmission cylinder 102 to rotate and transport the goods. That is to say, through the rotation of the driving rod 111, it is not only realized that the suitable height conveyor belt 1 is driven to lift and adjust, but also directly drives it to transport the goods after the adjustment is completed, which is practical.

[0031] The clamping mechanism includes a plurality of clamping blocks 112. The outer side of the clamping plate 107 is provided with clamping grooves. The clamping blocks 112 are adapted to the clamping grooves. One end of the clamping block 112 is fixedly connected with a slider 113.

One end of the slider 113 is fixedly connected to an extension rod 114, and the extension rod 114 slides on the inner side of the strip bracket 105. One end of the extension rod 114 is fixedly connected to a slider 2 115. A slide groove 2 is provided on the inner side of the strip bracket 105. The slider 2 115 is slidably matched with the slide groove 2, and a spring member is provided between the slider 2 115 and the slide groove 2. An oblique groove 121 is provided through the center of the slider 115, and a blocking rod 116 is provided through the oblique groove 121. The oblique groove 121 allows the blocking rod 116 to move. A vertical hole 1 is provided through the strip bracket 105, and the vertical hole 1 is provided for the blocking rod 116 to move up and down. A pair of movable blocks 117 are fixedly connected at both ends of the blocking rod 116, and a pair of spring telescopic rods 118 are provided at the upper ends of the movable blocks 117. Fixed blocks 119 are fixedly connected to the inner and outer sides of the strip bracket 105, and the spring telescopic rod 118 is connected to the fixed block 119.

A vertical hole 2 is provided through the strip bracket 105, and the vertical hole 2 is provided for the push rod 120 to move up and down. The two ends of the push rod 120 are respectively fixedly connected to a pair of movable blocks 117.

[0032] Preferably, a spring member is provided between the second slider 115 and the second slide slot, so that in the initial state, the second slider 115 and the first slider 113 are driven to deviate toward the clamping plate 107, so that a plurality of clamping blocks 112 are clamped into the clamping slot, thereby clamping the clamping plate 107. At this time, the strip bracket 105 can be lifted and adjusted. When the angle is adjusted, the second slider 115 and the first slider 113 are displaced away from the clamping plate 107, so that the clamping block 112 can be disengaged from the clamping slot, and the restriction of the clamping plate 107 is released. At this time, the clamping plate 107 can rotate with the driving rod 111 and the active transmission cylinder 102 to realize the transportation of goods. Preferably, a plurality of spring telescopic rods 118 are provided to facilitate the movable block 117 to move, guide and reset, and in the initial state, the push rod 120 and the blocking rod 116 are respectively at the lower ends of the vertical hole 2 and the vertical hole 1; when the strip bracket 105 is lifted, the limit bracket rod 201 and the sliding seat 202 are pulled to move, and when the angle is adjusted, the sliding seat 202 can be stuck in place by the bevel tooth clamping plate 204, and the driving motor of the driving rod 111 can be turned off, so that the strip bracket 105 loses power and applies gravity downward, and the lower end of the limit bracket rod 201 is restricted and immovable at this time, so that the strip bracket 105 moves relative to the push rod 120, the movable block 117 and the blocking rod 116, and the push rod 120 is displaced along the second vertical hole, and the blocking rod 116 is displaced along the first vertical hole and the inclined groove 121 at the same time, so that the second slider 115 is relatively displaced to pull the extension rod 114 and the slider 1 113 to move, so that the clamping block 112 is disengaged from the clamping groove, and the restriction of the clamping plate 107 can be released. In other words, there is no need to use an additional driving component to drive the slider 113. The bar bracket 105 can be driven by its own gravity until the push rod 120 is at the uppermost end of the second vertical hole (the upper end of the limiting bracket rod 201 is also in contact with the top of the adaptation groove). The bar bracket 105 can be stabilized and the clamping plate 107 can be automatically released from being stuck, thereby starting the transportation of goods. The process connection is smooth and the degree of automation is high.

An upper end of one side of the adapting rod 3 is rotatably connected to the lower end of the movable disk 110, and a roller 302 is rotatably connected to the lower end of one side of the adapting rod 3. A square groove is provided at the lower end of the base 9, in which a spring telescopic rod 2 303 is provided, and a square block 304 is slidably matched in the square groove, and the square block 304 is connected to the spring telescopic rod 2 303. A plug plate 305 is fixedly connected to the lower end of the square block 304, and an inclined surface is provided at one end of the plug plate 305, and the roller 302 rolls along the inclined surface. A pair of extended square rods 306 are fixedly connected to the other end of the plug plate 305, and an oblique chamfer is provided at the head end of the extended square rod 306. Trapezoidal wedge blocks 307 are fixedly connected to both ends of the oblique tooth clamping plate 204, and the trapezoidal wedge blocks 307 are matched with the extended square rod 306.

[0034] Preferably, when the loading and unloading transportation is completed, the height-adjustable conveyor belt 1 needs to be reset. At this time, the extended square rod 306 is driven by the plug plate 305 to move in the direction of the beveled toothed card plate 204. The beveled chamfer of the extended square rod 306 is matched with the trapezoidal wedge block 307, so that the extended square rod 306 pushes the trapezoidal wedge block 307 downward along its inclined surface, driving the beveled toothed card plate 204 to move downward, releasing the stuck sliding seat 202 and making it lose its position restriction. Then, under the action of gravity of the height-adjustable conveyor belt 1, it is pressed on the limit bracket rod 201 and slides. The seat 202 is pushed and slides at a constant speed along the convex groove 203 under the action of its own friction force. Since the strip bracket 105 applies pressure to the limit bracket rod 201, the push rod 120 and the stop rod 116 are respectively at the uppermost ends of the second vertical hole and the first vertical hole, until the strip bracket 105 is reset. Under the reset action of the spring telescopic rod 118, the movable block 117 is reset, and the clamping block 112 is also clamped into the inner side of the clamping disk 107 again, and the clamping disk 107 is re-limited, which is convenient for the next angle adjustment. Preferably, when the plug plate 305 needs to be driven to move, an avoidance groove is provided at the junction of the base 9 and the clamping disk 107, and a spring telescopic rod 3 8 is provided in the avoidance groove. The upper side of the spring telescopic rod 3 8 is provided with an arc-shaped tooth 801, and the arc-shaped tooth 801 is adapted to the clamping groove. The arrangement of the arc-shaped tooth 801 enables the clamping disk 107 to rotate in only one direction (the rotation direction is as follows Figure 4As shown), when rotating in the opposite direction, the engaging groove contacts the straight surface of the arc-shaped tooth 801 and cannot rotate; when the cargo is loaded and unloaded and transported, the driving rod 111 is driven by the motor assembly to rotate in the opposite direction. Since the engaging plate 107 cannot rotate, it is fixed, so that the driving rod 111 drives the movable plate 110 to reset and displace in the direction of the engaging plate 107, and at the same time drives the lower side adaptation rod 3 to displace, the guide rod 301 guides, and the adaptation rod 3 drives the roller 302 to displace, so that the roller 302 rolls along the inclined surface of the plug plate 305, thereby pushing the plug plate 305 to displace, and the stuck sliding seat 202 can be released, so that the height-appropriate conveyor belt 1 automatically descends and resets, that is, no additional driving assembly or control program is required to control the movement of the plug plate 305, thereby saving costs.

[0035] A wheel groove 7 is provided on the upper side of the base 9, and a support wheel 701 is provided inside the wheel groove 7. A support rod 702 is rotatably connected to the upper side of the support wheel 701. The support rod 702 passes through a plurality of thin narrow bands 101. A rotating shaft 703 is fixedly connected to the upper end of the support rod 702. Both ends of the rotating shaft 703 are rotatably connected to the strip bracket 105. The rotating shaft 703 is driven to rotate by motor three.

[0036] Preferably, in order to further reduce the load of the driving rod 111 and its motor assembly and ensure the stability of lifting the appropriate height conveyor belt 1, a support rod 702 is also provided. Specifically, the three-drive shaft 703 of the motor is rotated (since the motors are all existing technologies, they are not shown in the figure), thereby pushing the support rod 702 to rotate, and the support wheel 701 rolls along the wheel groove 7, further assisting the driving rod 111 to lift the appropriate height conveyor belt 1.

[0037] The head end of the strip bracket 105 is fixedly connected to a support plate 403, and the upper end of the support plate 403 is rotatably connected to a rotating disk 406. A pair of motors 1 and 2 are respectively provided on the outer sides of the pair of support plates 403. A plurality of fixed rods 405 are fixedly connected between the pair of rotating disks 406. The fixed rods 405 penetrate through the flip arm 401 and slide with it. The motor 2 drives one side of the rotating disk 406 to rotate. The inner side of the rotating disk 406 on one side is rotatably connected with a bidirectional threaded rod 404, which passes through the rotating disk 406 on the other side and the support plate 403 and is clearance-matched therewith. Motor 1 drives the bidirectional threaded rod 404 to rotate, and the bidirectional threaded rod 404 passes through a pair of flip arms 401 and is threadedly connected therewith.

[0038] Preferably, the bidirectional threaded rod 404 is driven to rotate by motor 1, thereby driving a pair of flip arms 401 to move relative to each other, and the fixed rod 405 is guided so that the flip arms 401 clamp the goods. Then, the rotating disk 406 on one side is driven to rotate by motor 2, thereby driving the fixed rod 405 and the flip arm 401 to flip, and the goods can be transported to the appropriate height conveyor belt 1.

[0039] A plurality of balls are arranged on the upper side of the diverter table 6 , and swing mechanical arms 504 are arranged at both ends of the end of the main channel 5 , and the swing mechanical arms 504 are driven to rotate by a rotary cylinder.

[0040] Preferably, when sorting and transportation are required, the swinging mechanical arm 504 is driven to rotate by a rotating cylinder, so that the goods on the diverter platform 6 are pushed into the first diverter channel 501, the second diverter channel 502 or the third diverter channel 503.
