Description

Technical Field

[0001] The present invention relates to a cargo transportation device, in particular to a container cargo handling mechanism. Background Art

[0002] In the logistics industry, loading and unloading are both labor-intensive and the most costly parts. There are various ways of carrying goods. Some are placed on pallets and directly transported together with the pallets, some are directly transported by adsorbing the cargo boxes, and even some still stay in the manual handling method, handling from the carriage inlet or the side opening of the carriage.

[0003] The traditional unloading method is to move the grasping structure to the corresponding position of the goods, grasp the goods onto a flat conveyor belt and convey them to the outside of the carriage. However, the grasping mechanism moves up and down, extending the unloading cycle. Therefore, in the prior art, part of the conveyor belt is set at a high position or a low position, and the adsorption is set to be movable, so as to shorten the distance between the grasping structure and the conveyor belt. However, in fact, the height and width of each vehicle are different. In the process of adapting to different vehicles, the entire cargo handling mechanism needs to frequently move in and out to adjust its own position, so as to unload the goods at different heights and widths. And the turnover time greatly extends the entire unloading cycle, thus increasing the transportation cost and transportation time.

[0004] Therefore, this case aims to provide a container cargo handling mechanism, which can not only unload goods efficiently, but also does not need to adjust its own position after entering the truck interior. It can automatically adjust the position of the conveying surface according to the width of the truck and the arrangement of the goods, thereby improving the cargo turnover efficiency. At the same time, the conveying platform can directly adjust the height of the upper or lower position on the platform vehicle, can span the bottom and the top of the box, and can adapt to most heights of containers.

[0024] The beneficial effects of the present invention are as follows:

[0025] Some existing transfer devices can also reach deep into the carriage of a truck to transfer goods. However, since the transfer devices generally have different diameters from the carriage and the adjustable area inside the carriage is limited, after unloading some areas, the transfer device needs to be moved out of the carriage, re-identified outside and then enter the carriage again for secondary unloading. This not only wastes a lot of time, but also is prone to errors in secondary alignment. Therefore, in the present invention, through the adsorption structure provided, while the original suction cup group has the function of adsorbing and transferring, a compensation group is added. When the width of the goods is at the normal width, the compensation group can increase the suction force on the basis of the adsorption structure, making the goods more stable during transfer. When the goods exceed the normal width, the compensation group can extend laterally from the adsorption structure, allowing the suction cup group to adsorb the goods in the normal area, while the compensation group adsorbs the goods exceeding the normal area, enabling the entire transfer device to cover the entire surface of the goods without secondary adjustment. The transfer structure only needs to be adjusted once and then can gradually penetrate into the carriage, improving the overall transfer efficiency and at the same time enhancing the transfer quality, and being able to more accurately identify and cover the corresponding area.

[0026] When the compensation group moves laterally towards the suction cup group, it requires a stable track and power. Otherwise, its own stability is prone to problems when receiving goods. Therefore, the compensation group of the present invention is provided with a separate auxiliary track and a suction cup compensation seat with the same power as the suction cup group. When it needs to move laterally, the motor drives the gear to drive the rack fixed on the suction cup compensation seat, thereby changing the position of the suction cup compensation seat and enabling the compensation group to move laterally stably.

[0027] In existing transfer equipment, goods are mostly picked up by the adsorption end and then placed on the conveyor belt for transportation. The steps and actions of the adsorption end need to be complexly edited, and the adsorption end needs to act repeatedly, resulting in a very slow transfer efficiency. Therefore, in the present invention, through the additional center guiding mechanism, the adsorption structure can adsorb a whole row of goods at the same time and place them on the center guiding mechanism. First, the goods in the middle are transported to the rear transfer rack through the middle transfer structure, and the side guiding structure transports the goods on the side to the position of the middle transfer structure, and then they are transported to the rear through the middle transfer structure again. During the operation of the side guiding structure, the adsorption structure can start adsorption again, so that only one adsorption action is required to complete the transfer of a whole row of goods, greatly increasing the overall transportation efficiency. Moreover, the action amplitude of the adsorption structure is small, the cycle is fast, and the precision is high. In the case where the above-mentioned adsorption structure can be extended, the side guiding structure in the present invention can also be extended laterally to match the width extension of the adsorption structure, so as to accommodate a carriage with a larger lateral area and have high adaptability.

[0028] When the middle transfer structure is in the process of transporting goods to the transfer rack, it also has the effect of receiving the goods input by the side guiding structure. Therefore, the middle transfer structure in the present invention not only has a conveyor belt capable of transporting goods to the rear transfer rack, but also has a middle guide roller capable of centering the goods, so that the goods can be transported to the rear at a relatively middle position. And in order to avoid slipping, a pushing buckle is also provided on the conveyor belt to push the goods, enabling customers to move to the rear in time from the position of the middle transfer structure.

[0029] Not all the guide rollers in the side guiding structure are powered, otherwise the overall energy cost is relatively high. Therefore, at least one power roller is provided in the side guiding structure of the present invention to assist multiple side guide rollers, and then the power roller and the side guide rollers are connected by means of an activity adjusting part, so that the side guide rollers also have power, enabling the goods to move to the middle faster and more stably. And in order to avoid the problem that the gap between the side guide rollers and between the side guide rollers and the power roller is too large, resulting in the goods slipping, an elastic compensation strip is also provided on the power roller or the side guide rollers, so that the goods have a larger contact area with the transfer device.

[0030] As mentioned above, the side guiding structure is adjustable, so the distance between the power roller and the side guide rollers will change to a certain extent. If traditional belts or chains are used, it is easy to be too tight or too loose to provide power. Therefore, the present invention uses two hinge plates and a movable wheel to connect the belt, which can automatically adjust the included angle of the two hinge plates according to the gap between the power roller and the side guide rollers, so that the belt can always be tightened and provide a transmission effect for the side guide rollers and the power roller.

[0031] Although the distance between the side guide roller and the power roller is stably adjusted through the above settings, the stability of the distal guide roller will be reduced due to the excessively long arrangement of the guide rollers. Therefore, in the present invention, the side guide rollers are divided into two regions of guide rollers, and two guiding structures, namely an inner guide rail and a compensation guide frame, are separately provided. The proximal guide rollers are arranged on the inner guide rail, and the distal guide rollers are arranged on the compensation guide frame and driven by a compensation power source, so as to ensure that both the proximal and distal ends can stably support the goods.

[0032] After the center feeding mechanism and the adsorption structure can complete the variable diameter in the width direction, the adaptability of the transfer equipment is greatly improved. However, the goods in the container are not simply horizontally distributed but stacked together. Therefore, there are some goods at higher positions that are difficult to take down. If the overall rack is directly adjusted, not only is the adjustment speed slow, but the overall movement amplitude is also large. Therefore, in the present invention, through the provided driving structure, firstly, the adsorption structure can be changed to the extended or retracted state through the lateral driving component to complete the process of the goods from inside the container to the center feeding mechanism. Secondly, the adsorption structure is pushed or retracted by the longitudinal driving component to rise or fall, so that the adsorption structure can not only adsorb the goods in the same row but also adsorb the goods on the upper layer, and the position change of a small area can be completed without large adjustment of the rack structure, thereby improving the practicability of the present invention.

[0033] Existing goods need to change their own height according to the height of the goods during the unloading stage in order to achieve the effect of rapid loading and unloading. However, the heights of different trucks and goods are different. If the adjustment is made in real time every time the goods arrive, it will require a relatively long unloading time. Therefore, the goods transfer platform provided by the present invention enables the platform to directly enter the interior of the truck through the movable chassis, and an adjustment transmission component is also provided on the movable chassis, which can enable the transmission rack to change its own height through the power system and the driven structure, so that the transmission rack reaches the highest or lowest point of the truck, and further enables the platform to not only adapt to vehicles with different goods heights but also gradually lower its own height as the height of the goods decreases, ensuring that there is a good receiving point throughout the unloading cycle, thereby avoiding unloading mistakes and improving the unloading effect at the same time.

[0034] The driven structure is the key to the movement of the transmission rack. Among them, the key to the adjustable direction of the transmission rack lies in the front driven end. When the first driving structure in the front driven end rotates, it drives the second turntable through the first transmission shaft via the first turntable, making the belt body at the front end rotate, and then driving the connecting piece to move up and down, thereby realizing the change of the position of the connecting piece, and further changing the position of the transmission rack connected to the connecting piece to adjust the transmission height in real time.

[0035] In order to fully ensure the movement accuracy of the belt body and thus the movement progress of the connecting piece, the first turnover device and the second turnover device of the present invention do not simply use a gear-belt drive. Instead, through the cooperation among the mating gear, the tension gear, and the adjusting gear, the belt body at the front end can move in a taut state during movement, thereby achieving the most accurate movement accuracy. Furthermore, the transmission rack can reach a relatively accurate position, so that the goods can be caught by the transmission rack immediately after being adsorbed.

[0036] The heights of different trucks are different. The heights of some trucks are relatively small. Therefore, if the height of the platform is set too high, it is easy to cause small trucks to be unable to enter. If the platform is set too low, the transmission rack after displacement still cannot reach the highest height of large trucks. Therefore, the present invention provides a rear driven end at the position of the rear chassis. By means of the rear driven end, the position of the belt body at the rear end can be changed, thereby driving the height of the connecting piece at the rear end. Furthermore, the transmission rack that has already changed its height can be lifted again, so that the height of the platform can be set relatively low, and then the height of the entire transmission rack can be raised to a position flush with the highest height of large trucks by means of secondary lifting.

[0037] Although the transmission rack can achieve the effect of transporting goods, it does not have the effect of limiting and guiding the goods. The goods are prone to slipping or falling from the lateral position. Therefore, the present invention also provides a side railing at the position of the transmission rack to limit the lateral side of the transmission rack. In order to adapt to the position change of the transmission rack, the side railing is not fixedly arranged, but is connected to the transmission rack through a movable connecting rod. Thus, during the rising and falling process of the transmission rack, the height of the side railing can also change, and it is not easy to collide with other structures.

[0038] During the up and down movement of the transmission rack, it all depends on the cooperation between the connecting piece and the belt body. The connecting piece is only connected to the belt body, and it receives less guidance during its movement. Then, when it returns to its original position, it is prone to deviation from the original position. Therefore, the present invention provides a short track and a long track to guide the movement of the connecting piece in two directions, so that it can return to the original position along the original track after movement, thereby achieving a very precise effect for each movement.

[0039] To sum up, through the multi-angle cooperation of the adsorption structure, the centering feeding mechanism, the driving structure, the movable rack, and the adjusting transmission component, the entire goods handling mechanism can adapt to most carriages on the market, so that the application range of the present invention is extremely large and the adaptability is extremely high.

The plurality of connecting pieces 302 are locked on a plurality of belts 303 on the driven structure 202. When the driven structure 202 drives the belts 303 to move up and down, the belts 303 drive the connecting pieces 302 and the transmission rack 301 connected to the connecting pieces 302 to lift or lower.

[0063] During the overall operation, the entire surface of the cargo is identified by the visual recognition system on the mobile chassis 1 (the identification method is the existing technology and will not be outlined in detail). After identification, the driving wheels 101 allow the entire mobile chassis 1 to move to the corresponding area of ​​the truck, and then the first driving structure 1021 in the driving power system 102 is used to lift the transmission frame 301 to the corresponding position of the cargo, and the width of the compensation group 24 and the push-out distance of the compensation power source 3213 are adjusted according to the width of the cargo, and then unloading begins, and the height of the transmission frame 301 is continuously adjusted during the unloading process.

[0064] Some existing transfer equipment can also go deep into the compartment of the truck to transfer goods, but because the transfer equipment is generally not of the same diameter as the compartment and the area available for adjustment in the compartment is limited, the transfer equipment needs to be moved out of the compartment after unloading part of the area, and then enter the compartment for secondary unloading after re-identification on the outside, which not only wastes a lot of time, but also easily leads to errors in the secondary alignment. Therefore, the present invention can add a compensation group 24 while the original suction cup group 23 has the function of adsorption and transfer through the adsorption structure 20. When the width of the goods is at a normal width, the compensation group 24 can increase the suction force on the basis of the adsorption structure 20, so that the goods are more stable during transfer. When the goods exceed the normal width, the compensation group 24 can extend from the side of the adsorption structure 20, so that the suction cup group 23 adsorbs the goods in the normal area, and the compensation group 24 adsorbs the goods beyond the normal area, so that the entire transfer device can cover the entire surface of the goods without secondary adjustment, and the transfer structure can gradually go deeper into the compartment after only one adjustment, so that the overall transfer efficiency is improved, and the transfer quality is also improved, and the corresponding area can be more accurately identified and covered.

[0065] The compensation group 24 requires a stable trajectory and power when moving laterally toward the suction cup group 23, otherwise its own stability is likely to have problems when receiving goods. Therefore, the compensation group 24 of this embodiment includes a sub-track 241 arranged on the side of the line slot box 21 close to the cargo pickup, and a suction cup compensation seat 242 is slidably installed on the sub-track 241. The suction cup compensation seat 242 is provided with a number of suction cups identical to the suction cup group 23, and a rack 243 is locked at the top of the suction cup compensation seat 242. The rack 243 is driven by a motor with a gear. When the motor is actuated, it drives the suction cup compensation seat 242 to move inward or outward along the sub-track 241. The compensation group 24 is provided with a separate sub-track 241 and a suction cup compensation seat 242 with the same power as the suction cup group 23. When it needs to move laterally, the motor drives the gear to drive the rack 243 fixed on the suction cup compensation seat 242 to move, thereby changing the position of the suction cup compensation seat 242 so that the compensation group 24 can move sideways stably.

[0066] In the existing transfer equipment, the goods are mostly taken off by the suction end, and then placed on the conveyor belt for transportation. The steps and actions of the suction end need to be edited in a complex manner, and the suction end needs to act repeatedly, and the efficiency of the transfer is very slow. Therefore, the present invention adds a central material guide mechanism 30, and the suction structure 20 can simultaneously absorb a whole row of goods, place them on the central material guide mechanism 30, first transfer the middle goods to the rear end transfer rack through the middle transfer structure 31, and the lateral material guide structure 32 is at the position of transferring the side goods to the middle transfer structure 31. The cargo is then transported to the rear end through the middle transmission structure 31 again, and the adsorption structure 20 can start adsorption again during the movement of the lateral guide structure 32, so that only one adsorption movement is required to complete the transfer of the entire row of cargo, and the overall transportation efficiency is greatly improved. In addition, the adsorption structure 20 has a small movement amplitude, a fast cycle, and a high precision. In the case where the above-mentioned adsorption structure 20 is extendable, the lateral guide structure 32 in the present invention can also be extended laterally to match the width extension of the adsorption structure 20, and can accommodate carriages with a larger lateral area, with high adaptability.

[0067] When the middle transmission structure 31 has the process of transmitting to the transmission rack, it also has the effect of receiving the goods input by the lateral material guide structure 32. Therefore, the middle transmission structure 31 of this embodiment includes two transmission areas arranged in the mounting frame 10, and the transmission includes a plurality of middle guide rollers 311. The shaft heads of adjacent middle guide rollers 311 are connected by belts and driven by at least one driving motor. A transmission belt 312 is also arranged between two adjacent middle guide rollers 311. A push buckle 313 is connected to the transmission belt 312. The push buckle 313 pushes the goods to one side of the transmission rack when the transmission belt 312 rotates. The middle transmission structure 31 not only has a transmission belt 312 that can transport the goods to the rear end transmission rack, but also has a middle guide roller 311 that can center the goods, so that the goods can be transmitted to the rear end at a relatively middle position, and in order to avoid slipping, a push buckle 313 is also arranged on the transmission belt 312 to push the goods, so that customers can go to the rear end from the position of the middle transmission structure 31 in time.

[0068] In the side guide structure 32, not all of the guide rollers are powered. Otherwise, the overall energy cost would be relatively high. Therefore, in this embodiment, the side guide structure 32 includes a number of side guide rollers 321 slidably disposed on both sides of the front end of the mounting frame 10. At least one power roller 322 is provided between the side guide rollers 321. The power roller 322 is connected to the side guide rollers 321 and between the side guide rollers 321 through an active adjustment member 323. At least one compensation strip 324 is connected between the mounting seats outside the shaft heads at both ends of the power roller 322 or the side guide rollers 321. The side guide structure 32 is provided with at least one power roller 322 to assist a plurality of side guide rollers 321, and then the power roller 322 and the side guide rollers 321 are connected by means of the active adjustment member 323, so that the side guide rollers 321 also have power, enabling the goods to move towards the middle faster and more stably. In order to prevent the problem of the goods slipping due to excessive gaps between the side guide rollers 321 and between the side guide rollers 321 and the power roller 322, an elastic compensation strip 324 is also provided on the power roller 322 or the side guide rollers 321, so that the goods have a larger contact area with the transfer device.

[0069] As mentioned above, the side guide structure 32 is adjustable. Therefore, the distance between the power roller 322 and the side guide rollers 321 will change to a certain extent. If traditional belts or chains are used, it is easy to be too tight or too loose and unable to provide power. Therefore, in this embodiment, the active adjustment member 323 includes a hinge plate 3231 rotatably connected to the shaft head of the power roller 322 or the side guide rollers 321. An active wheel 3232 is connected between two adjacent hinge plates 3231. The active wheel 3232 is connected to the shaft head of the power roller 322 or the side guide rollers 321 through a belt. By using two hinge plates 3231 and an active wheel 3232 to connect the belt, the included angle between the two hinge plates 3231 can be automatically adjusted according to the gap between the power roller 322 and the side guide rollers 321, so that the belt can always be tightened and provide a transmission effect for the side guide rollers 321 and the power roller 322.

[0070] Although the distance between the side guide roller 321 and the power roller 322 is stably adjusted through the above settings, the excessively long arranged guide rollers will reduce the stability of the distal guide rollers. Therefore, in this embodiment, the side guide roller 321 is divided into an inner guide roller and a compensation guide roller. The inner guide roller is slidably installed on an inner guide rail 3211, and the compensation guide roller is installed on a compensation guide frame 3212. A compensation power source 3213 is locked at the bottom of the mounting bracket 10, and the output end of the compensation power source 3213 is connected to the lower part of the compensation guide frame 3212. When the total length of all the inner guide rollers is less than the width of the goods, the compensation power source 3213 pushes out the compensation guide frame 3212, so that the length of the inner guide roller and the compensation guide roller is greater than or equal to the width of the goods. The side guide roller 321 is divided into two areas of guide rollers, and two guiding structures, namely the inner guide rail 3211 and the compensation guide frame 3212, are provided separately. The proximal guide roller is arranged on the inner guide rail 3211, and the distal guide roller is arranged on the compensation guide frame 3212. Then, driven by the compensation power source 3213, the proximal and distal ends can both stably support the goods.

[0071] When the goods move towards the conveying rack, in order to make it move more towards the middle position and avoid misaligned stacking on the middle conveying structure 31, a guiding strip 3214 is provided at the upper end of the compensation guide frame 3212. The guiding strip 3214 is of an L-shaped structure, and a boosting roller 3215 is provided on the side of the guiding strip 3214 close to the middle conveying structure 31. Thus, the goods slightly closer to the side can be guided by the guiding strip 3214, and if the corners of some goods do not contact the middle conveying structure 31, they can also be transmitted to the rear end under the action of the boosting roller 3215.

[0072] In order to improve the smoothness of the goods being adsorbed and transported during unloading, an incoming goods guide roller 11 is provided on the side of the mounting bracket 10 close to goods picking, and a compensation guide roller 12 is provided on the mounting seat at the shaft head of the compensation guide roller close to the goods picking side. Even when the goods contact the mounting bracket 10, they can be guided by the incoming goods guide roller 11 and the compensation guide roller 12.

[0073] Since the entire adsorption structure 20 needs to move back and forth frequently during goods picking and unloading, it is relatively difficult to arrange the air pipeline and several electric wires, and it is difficult to set up wire grooves. Therefore, in this embodiment, a movable wire clip 40 is added. The movable wire clip 40 includes a first fixed seat 41 locked on the wire groove box 21 and a second fixed seat 42 locked at the rear end position of the mounting bracket 10. A wire groove accommodating frame 43 with a hollow interior is movably installed between the first fixed seat 41 and the second fixed seat 42. The middle part of the wire groove accommodating frame 43 is guided by a guiding rail 44, so that the air pipeline and several electric wires can be arranged in the wire groove accommodating frame 43 to bind these lines, and they are always in a limited route under the limitation of the guiding rail 44, making the lines more stable.

[0074] When the circuit is accommodated in the wire groove accommodating frame 43, it will elongate or shorten with the change of the wire groove accommodating frame 43. Specifically, the wire groove accommodating frame 43 includes a hollow first accommodating block 431, a second accommodating block 432, a third accommodating block 433, and a fourth accommodating block 434 that are sequentially connected end to end. The first accommodating block 431, the second accommodating block 432, the third accommodating block 433, and the fourth accommodating block 434 are hinged to each other. The hinged position between the second accommodating block 432 and the third accommodating block 433 is slidably connected to the guide rail 44 through a slider 435. On one side of the first accommodating block 431 close to the second accommodating block 432, a first limiting button 436 is provided. On one side of the second accommodating block 432 close to the third accommodating block 433, a second limiting button 437 is provided. On one side of the fourth accommodating block 434 close to the third accommodating block 433, a third limiting button 438 is provided. The hollow first accommodating block 431, the second accommodating block 432, the third accommodating block 433, and the fourth accommodating block 434 will move along with the movement of the adsorption structure 20. After the adsorption structure 20 is completely retracted, the positions of the accommodating blocks can be regulated by the first limiting button 436, the second limiting button 437, and the third limiting button 438, so as to prevent the accommodating blocks from colliding with each other.

[0075] After the center feeding mechanism 30 and the adsorption structure 20 can complete the diameter change in the width direction, the adaptability of the transfer equipment is greatly improved. However, the goods in the container are not simply horizontally distributed, but stacked together. Therefore, there are some goods at higher positions that are difficult to remove. If the overall frame is directly adjusted, not only is the adjustment speed slow, but the overall movement range is also large. Therefore, in the present invention, through the provided driving structure 50, firstly, the extending or retracting state of the adsorption structure 20 can be changed through the lateral driving component 51 to complete the process of the goods from the inside of the box to the center feeding mechanism 30. Secondly, the adsorption structure 20 can be pushed out or retracted through the longitudinal driving component 52 to rise or fall, so that the adsorption structure 20 can not only adsorb the goods in the same row, but also adsorb the goods on the upper layer, and the position change of a small area can be completed without large adjustment of the frame structure, thereby improving the practicality of the present invention.

[0076] During the use of the driving structure 50, it is movably arranged on the mounting frame 10. In order to better distinguish the installation positions of the center guiding mechanism 30 and the driving structure 50, the mounting frame 10 includes a front mounting frame 13 for accommodating the center guiding mechanism 30. One end of the front mounting frame 13 away from the incoming goods is connected with a lower mounting frame 15. The upper end of the lower mounting frame 15 is connected with an upper mounting frame 14. The transverse driving component 51 includes an upper hinge seat 511 fixed on the upper mounting frame 14. An expansion and retraction push rod motor 512 is hinged on the upper hinge seat 511. The other end of the expansion and retraction push rod motor 512 is movably installed on the back side of the wire groove box 21. The longitudinal driving component 52 includes a first lower hinge seat 521 arranged inside the lower mounting frame 15. A second lower hinge seat 523 is arranged on the back side of the wire groove box 21. A reversing push rod motor 522 is arranged between the first lower hinge seat 521 and the second lower hinge seat 523. When the adsorption structure 20 is in use, the taking and re-unloading of goods are realized through the extension and retraction of the expansion and retraction push rod motor 512. When it is necessary to adsorb goods on a higher layer, the wire groove box 21 is pushed out by the reversing push rod motor 522 to lift the wire groove box 21 upward. At the same time, since the expansion and retraction push rod motor 512 is connected to the wire groove box 21, the expansion and retraction push rod motor 512 also needs to be set in a hinged state. The driving structure 50 is set to operate in multiple dimensions and cooperate with the high adaptability changes of the adsorption structure 20 and the center guiding mechanism 30, so that the entire batch transfer device can adapt to most trucks and containers on the market and improve the applicable scenarios of this embodiment.

[0077] In the existing goods unloading stage, it is necessary to change its own height according to the height of the goods in order to achieve the effect of rapid loading and unloading. However, the heights of different trucks and goods are different. If the adjustment is made in real time every time after the goods arrive, it will require a relatively long unloading time. Therefore, the goods transfer platform provided by the present invention enables the platform to directly enter the interior of the truck through the movable chassis 1, and an adjustment transmission component 3 is also arranged on the movable chassis 1, which can enable the transmission rack 301 to change its own height through the power system 102 and the driven structure 202, so that the transmission rack 301 can reach the highest or lowest point of the truck, and further enable the platform to not only adapt to vehicles with different goods heights, but also gradually lower its own height as the height of the goods decreases, ensuring that there is a good goods receiving point throughout the unloading cycle, thereby avoiding unloading mistakes and improving the unloading effect at the same time.

[0078] During the up or down adjustment of the transmission rack 301, the transmission rack 301 cannot be adjusted in place, but needs to undergo some deformation. Therefore, in the mobile chassis 1 of this embodiment, it includes a front chassis 103 and a rear chassis 104. The height of the rear chassis 104 is higher than that of the front chassis 103. Guide rails 105 are provided on both sides of the tops of the front chassis 103 and the rear chassis 104. The movable rack 2 is slidably engaged with the guide rails 105. A vacuum pump is provided in the front chassis 103. The movable rack 2 is movable, and its movement is due to the cooperation with the guide rails 105 on the mobile chassis 1, so that the position change of the movable rack 2 itself can be realized. Furthermore, when the height of the transmission rack 301 installed on the movable rack 2 changes, mechanical interference is not likely to occur. The vacuum pump is a structure that provides power for the adsorption end. Due to its large size, it is also installed in the front chassis 103 with a lower height and a larger space.

[0079] Since a vacuum pump and other power structures need to be installed inside the entire mobile chassis 1, it is difficult to set up a four-wheel drive structure inside the platform. The movement of the entire movable rack 2 and the power system 102 are also segmented. In this embodiment, the inner side of the mobile chassis 1 is divided into a front chassis 103 and a rear chassis 104, and most of the power structures are integrated into the front chassis 103, so that the entire structure can be made lower, avoiding the overall height of the platform being increased due to an overly high vehicle bottom, and further avoiding being unable to enter some small vehicles.

[0080] The driven structure 202 is distributed on the entire movable rack 2. However, since it is difficult to form a linkage between the front and rear ends, its front end and rear end are driven separately. Therefore, the power system 102 of this embodiment includes a first driving structure 1021 provided in the front chassis 103 and a second driving structure 1022 provided in the rear chassis 104. The first driving structure 1021 and the second driving structure 1022 are both used to drive the driven structure 202. A linear driving member 1023 is also installed on the rear chassis 104. The output end of the linear driving member 1023 is connected to the movable frame 201. When the linear driving member 1023 extends, the movable frame 201 moves towards the end for picking up goods. The power system 102 has multiple driving structures, and the linear driving member 1023 for driving the movable rack 2 itself is also provided on the mobile chassis 1, so that the movement of the movable rack 2 does not conflict with the mobile chassis 1.

[0081] The entire movable frame 201 has an integral structure. However, to adapt to the shape of the movable chassis 1, it is also divided into two parts. Specifically, the movable frame 201 includes a front frame 2011 located at the position of the front chassis 103, and a rear frame 2012 is provided on the rear chassis 104. The front frame 2011 and the rear frame 2012 are connected by a plurality of connecting arms. Sliding seats 2013 that cooperate with the guide rails 105 are provided at the lower ends of the front frame 2011 and the rear frame 2012. The output end of the linear drive member 1023 is connected to one of the connecting arms. When the linear drive member 1023 extends, the front frame 2011 and the rear frame 2012 move forward simultaneously. For the convenience of their movement, the front frame 2011 and the rear frame 2012 are integrally arranged. The linear drive member 1023 can drive one end to drive the other end to move, so that the position of the entire movable frame 201 can be changed.

[0082] The driven structure 202 is the key to the movement of the transmission rack 301. The driven structure 202 includes a front driven end 2021 and a rear driven end 2022 provided on the sliding seat 2013. The front driven end 2021 includes a front connecting portion 20211 connected to the first drive structure 1021. The front connecting portion 20211 is connected to the first turnover device 20212 through a belt. The first turnover device 20212 is connected to the second turnover device 20214 through a first transmission shaft 20213. The first turnover device 20212 and the second turnover device 20214 are both connected to the front end belt body 303. The top of the front end belt body 303 is wound around the first fixed pulley member 20215. The front end connecting member 302 is locked on the belt body 303 and moves up and down with the belt body 303. Among them, the key to the adjustable direction of the transmission rack 301 lies in the front driven end 2021. When the first drive structure 1021 in the front driven end 2021 rotates, it drives the second turnover device 20214 through the first turnover device 20212 via the first transmission shaft 20213, causing the front end belt body 303 to rotate, and then driving the connecting member 302 to move up and down, so as to change the position of the connecting member 302, and further change the position of the transmission rack 301 connected to the connecting member 302, and adjust the transmission height in real time.

[0083] In order to fully ensure the movement accuracy of the belt body 303 and thus ensure the movement progress of the connecting member 302, in this embodiment, the first turnover device 20212 and the second turnover device 20214 have the same structural size. The first turnover device 20212 includes a turnover gear 202121 connected to the belt. One side of the turnover gear 202121 close to the first transmission shaft 20213 is connected with a pair of docking seats 202122, and the side of the turnover gear 202121 far from the first transmission shaft 20213 is connected with a mating gear 202123. A tension gear 202124 is installed on the front frame 2011, and the lower end of the belt body 303 is connected to an adjusting gear 202125. The mating gear 202123, the tension gear 202124, and the adjusting gear 202125 are all connected by belts. The first turnover device 20212 and the second turnover device 20214 are not a simple gear-belt drive, but through the cooperation among the mating gear 202123, the tension gear 202124, and the adjusting gear 202125, the front belt body 303 can move in a taut state when moving, so as to achieve the most accurate movement accuracy, and then enable the transmission rack 301 to reach a relatively accurate position, so that it can be caught by the transmission rack 301 after the goods are adsorbed.

[0084] The heights of different trucks are different, and the heights of some trucks are relatively small. Therefore, if the height of the platform is set too high, it is easy for small trucks to be unable to enter. If the platform is set too low, the displaced transmission rack 301 still cannot reach the highest height of large trucks. Therefore, the rear driven end 2022 of this embodiment includes a rear connection part 20221 connected to the second driving structure 1022. The rear connection part 20221 is connected to the third turnover device 20222 through a belt. The third turnover device 20222 is connected to the fourth turnover device 20224 through the second transmission shaft 20223. The third turnover device 20222 and the fourth turnover device 20224 are both connected to the rear belt body 303. The top of the rear belt body 303 is wound around the second fixed wheel member 20225. The rear connecting member 302 is locked on the belt body 303 and moves up and down with the belt body 303. The rear driven end 2022 is arranged at the position of the rear underframe 104. By means of the rear driven end 2022, the position of the rear belt body 303 can be changed, thereby driving the height of the rear connecting member 302, and then enabling the transmission rack 301 whose height has been changed to be lifted again, so that the height of the platform can be set lower, and then the height of the entire transmission rack 301 can be raised to a position flush with the highest height of large trucks by means of secondary lifting.

[0085] Although the transmission rack 301 can achieve the effect of transporting goods, it does not have the effect of limiting and guiding the goods, and the goods are likely to slip or fall from the side position. Therefore, a side railing 304 is movably installed at the upper end of the transmission rack 301 in the embodiment. The side railing 304 includes a plurality of connecting rods 3041 hinged to the outside of the transmission rack 301. The top of the connecting rod 3041 is hinged with a side railing 3042. One side of the side railing 3042 close to the goods pickup end is hinged to the mounting frame 10, and the side of the side railing 3042 away from the goods pickup end is hinged to the outside of the transmission rack 301. The side railing 304 is provided at the position of the transmission rack 301 to limit the side of the transmission rack 301. In order to adapt to the position change of the transmission rack 301, the side railing 304 is not fixedly arranged, but is connected to the transmission rack 301 through the movable connecting rod 3041. Thus, during the ascending and descending process of the transmission rack 301, the height of the side railing 304 can also change, and it is not easy to collide with other structures.

[0086] During the up and down movement of the transmission rack 301, it all depends on the cooperation between the connecting piece 302 and the belt body 303. The connecting piece 302 is only related to the belt body 303, and it is less guided during its movement. Then, it is easy to deviate from the original position when it is reset. Therefore, a short track 3011 is provided on the outside of the transmission rack 301 in this embodiment, and long tracks 2024 are provided on the inner sides of the front frame 2011 and the rear frame 2012. The connecting piece 302 cooperates with the short track 3011 and the long track 2024 respectively. By providing the short track 3011 and the long track 2024, the movement of the connecting piece 302 can be guided in two directions, so that it can return to the original position along the original track after its movement, thus making each movement achieve a very precise effect.

[0087] The length of the transmission rack 301 is not sufficient to connect the goods with the processing equipment in the next stage. Therefore, a driven machine platform 305 is hinged at the end of the transmission rack 301 in this embodiment. A fixed machine platform 306 is installed at the tail end of the driven machine platform 305. The fixed machine platform 306 is connected to the movable rack 2 through a fixing member 307. Among them, the driven machine platform 305 does not have a separate power structure and will be linked with the transmission rack 301 through the hinge relationship, while the fixed machine platform 306 is fixedly connected to the movable rack 2 through fixing members 307 such as a fixing frame and an inclined rod, and its position will not change.

[0088] In summary, through the multi-angle cooperation of the adsorption structure 20, the centering material guiding mechanism 30, the driving structure 50, the movable rack 2, and the adjustable transmission assembly 3, the entire goods processing mechanism can adapt to most carriages on the market, so that the application range of the present invention is extremely large and the adaptability is extremely high.

[0089] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
