Description

Technical Field

[0001] The present invention relates to a cargo transfer method, in particular to a cargo transfer method of an automatic loading and unloading platform. Background Art

[0002] In the logistics industry, loading and unloading are both labor-intensive and cost-intensive. There are many ways to load cargo. Some are placed on pallets and transported directly with the pallets, some are directly transported by suction through cargo boxes, and some are even still transported manually from the entrance or side of the carriage.

[0003] The traditional unloading method is to move the grabbing structure to the corresponding position of the goods, grab the goods onto the flat conveyor belt and transport them to the outside of the car. However, the grabbing mechanism moves up and down, which prolongs the unloading cycle. Therefore, some existing technologies set the position of the conveyor belt to a high position or a low position, and set the adsorption to an active state, thereby shortening the distance between the grabbing 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 exchange and handling mechanism needs to frequently go in and out to adjust its own position, so that it can unload goods of different heights and widths. The turnover time greatly prolongs the entire unloading cycle, thereby increasing transportation costs and transportation time.

[0004] Therefore, this case aims to provide a transfer method for an automatic loading and unloading platform, which can not only continuously adjust its own state in real time according to the width and height of the goods, but also adapt to most cargo box compartments. Summary of the Invention

[0005] The present invention provides a method for transferring an automatic loading and unloading platform, which can effectively solve the above problems.

[0006] The present invention is achieved in that:

[0007] A method for transferring an automatic loading and unloading platform comprises the following steps:

[0008] S1: Install a movable frame and a power system on the mobile chassis, install a transmission frame inside the movable frame, and install an adsorption structure and a central material guiding mechanism on the side of the transmission frame close to the pickup;

[0009] S2: Move the entire mobile chassis to the entrance of the truck compartment, reset the power system, make the transmission rack reach the lowest position, reset the adsorption structure and the central material guide mechanism, so that the adsorption structure and the central material guide mechanism are flush with the width of the mounting frame;

[0010] S3: The overall width of the box and the area of the cargo inside the box are obtained through the visual system, and the obtained data are sent to the power system, adsorption structure, and centering material guide mechanism;

[0011] S4: Drive the running wheels of the mobile chassis according to the data fed back by the vision system, so that the mobile chassis is positioned in front of the cargo surface;

[0012] S5: Based on the data fed back by the vision system, the conveyor rack is lifted to the corresponding position of the goods, the width of the adsorption structure and the central material guide mechanism is adjusted, and the adsorption structure and the central material guide mechanism are pushed out by the driving mechanism to adsorb the goods, and the goods are transported to the rear end through the conveyor rack;

[0013] S6: Gradually adjust the height of the transmission rack through the power system until the cargo height given by the visual system is 0, and it is determined that the cargo unloading on this side is completed, and the mobile chassis is fed forward;

[0014] S7: Repeat S5 to S6 until the visual system determines that there is no cargo in the current carriage and moves the chassis out of the carriage.

[0015] As a further improvement, the S3 specifically includes:

[0016] S31: Obtain the length and width of the truck compartment;

[0017] S32: Obtain the length and width of the entire surface of the goods;

[0018] S33: Obtain the quantity and height of a single row of goods.

[0019] As a further improvement, moving the transport rack to the bottom position of the topmost box according to the data fed back by the visual system specifically includes: raising the end of the transport rack close to the pickup through the front end of the power system so that the transport rack reaches the bottom end of the topmost cargo.

[0020] As a further improvement, if the height of the topmost cargo is higher than the height of the already raised transport rack, the rear end of the transport rack away from the cargo pickup is raised through the rear end of the power system, so that the already raised transport rack is raised a second time.

[0021] As a further improvement, the adjustment of the width of the adsorption structure and the central material guiding mechanism specifically includes: identifying the width of a single row of goods based on the width of the entire surface of the goods, and judging whether the width of the single row of goods exceeds the width of the mounting rack; if the width of the single row of goods is within the width range of the mounting rack, the adsorption structure directly pushes out the adsorption; if the width of the single row of goods exceeds the width of the mounting rack, the adsorption structure and the central material guiding mechanism simultaneously expand outward until they are the same width as the goods.

[0022] As a further improvement, an adsorption structure is movably mounted on the driving structure, the adsorption structure includes a trough box connected to the driving structure, a number of solenoid valves are arranged in the trough box, all of the solenoid valves are connected to a vacuum pump through air pipes, a movable suction cup group is provided on the side of the trough box close to the cargo picking, and a compensation group is also provided on the side of the trough box close to the cargo picking. When the width of the cargo is greater than the length of the suction cup group, the compensation group extends away from the suction cup group to be equal to the width of the cargo.

[0023] As a further improvement, the central material guiding mechanism includes a central transmission structure arranged in the middle of the inner side of the mounting frame, the central transmission structure is adjacent to the transmission frame away from the side of picking up the goods, and lateral material guiding structures are installed on both sides of the central transmission structure. After the suction cup group or the compensation group adsorbs the goods to the lateral material guiding structure, it moves toward the central transmission structure through the lateral material guiding structure and moves to the transmission frame through the central transmission structure. The lateral material guiding structure includes a first state and a second state. When the width of the goods is equal to the length of the mounting frame, the lateral material guiding structure is in the first state. When the width of the goods exceeds the length of the mounting frame, the lateral material guiding structure extends laterally to the second state.

[0024] As a further improvement, the driving structure includes a transverse driving component and a longitudinal driving component connected to the wire trough box. The transverse driving component pushes the adsorption structure laterally and changes the height through the longitudinal driving component.

[0025] As a further improvement, a plurality of walking wheels are provided at the bottom of the mobile base, a power system is provided on the inner side of the mobile base, and a movable frame is movably provided on the top of the mobile base, the movable frame includes a movable frame that moves relative to the mobile base, and a driven structure connected to the power system is provided on the movable frame.

[0026] As a further improvement, the inner side of the transmission frame is provided with several transmission surfaces for transmitting goods to the rear end, and the outer side of the transmission frame is movably installed with several connecting parts, and several of the connecting parts are locked on several belt bodies on the driven structure. When the driven structure drives the belt body to move up and down, the belt body drives the connecting parts and the transmission frame connected to the connecting parts to lift or lower.

[0027] The beneficial effects of the present invention are:

[0028] The transfer method of the present invention uses a visual system for recognition and can analyze the different parameters of the entire surface of the goods, thereby adjusting the height of the transmission frame and the width of the adsorption structure and the central material guiding mechanism according to the parameters, so as to adapt to truck compartments of different sizes and diameters, without the need for manual adjustment, and without the phenomenon of adjustment errors. It has high adaptability and high adjustment accuracy.

[0029] Some existing transfer equipment can also go deep into the compartment of the truck to transfer goods, but since 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 a second unloading after re-identification on the outside. This not only wastes a lot of time, but also the secondary alignment is prone to errors. Therefore, the present invention sets an adsorption structure, which can add a compensation group while the original suction cup group has the adsorption and transfer function. When the width of the goods is at a normal width, the compensation group can increase the suction force on the basis of the adsorption structure, so that the goods are more stable during transfer. When the goods exceed the normal width, the compensation group can extend from the side of the adsorption structure, allowing the suction cup group to adsorb the goods in the normal area, and the compensation group adsorbs the goods beyond the normal area, so that the entire transfer device can cover the entire surface of the goods without secondary adjustment. The transfer structure can gradually go deeper into the compartment after only one adjustment, and the overall transfer efficiency is improved. At the same time, the transfer quality is also improved, and the corresponding coverage area can be more accurately identified.

[0030] In existing transfer equipment, most of the goods are taken off by the adsorption end and then placed on the conveyor belt for transportation. The steps and actions of the adsorption end need to be complicatedly edited, and the adsorption end needs to move repeatedly, and the transfer efficiency is very slow. Therefore, the present invention adds a central material guiding mechanism, and the adsorption structure can adsorb a whole row of goods at the same time and place them on the central material guiding mechanism. The goods in the middle are first transferred to the transfer rack at the rear end through the central transmission structure, and the lateral material guiding structure transports the side goods to the position of the central transmission structure, and then transports them to the rear end through the central transmission structure again. In the process of the action of the lateral material guiding structure, the adsorption structure can start adsorption again, so that only one adsorption action is needed to complete the transfer of the whole row of goods, and the overall transportation efficiency is greatly improved. In addition, the action amplitude of the adsorption structure is small, the cycle is fast, and the precision is high. In the case that the above-mentioned adsorption structure is extendable, the lateral material guiding structure in the present invention can also be extended laterally to match the width extension of the adsorption structure, and can undertake carriages with larger lateral areas, with high adaptability.

[0031] After the central material guiding mechanism and the adsorption structure 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 distributed horizontally, but stacked together. Therefore, some goods distributed at higher positions are difficult to remove. If the overall frame is adjusted directly, not only the adjustment speed is slow, but the overall movement amplitude is also large. Therefore, the present invention, through the set driving structure, can first change the extension or retraction state of the adsorption structure through the horizontal driving component, so that it can complete the process of moving the goods from the box to the central material guiding mechanism. Secondly, the longitudinal driving component is pushed out or retracted to make the adsorption structure 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. The position change of a small area can be completed without large-scale adjustment of the frame structure, thereby improving the practicality of the present invention.

[0032] Existing cargo needs to change its own height according to the height of the cargo during the unloading stage in order to achieve the effect of fast loading and unloading. However, the heights of different trucks are different, and the heights of the cargo are different. If real-time adjustments are made every time the cargo arrives, it will take a lot of time to unload separately. Therefore, the cargo transfer platform provided by the present invention can allow the platform to directly enter the interior of the truck through a mobile chassis, and a transmission frame is also provided on the mobile chassis, which can allow the transmission frame to change its own height through a power system and a driven structure, so that the transmission frame can reach the highest point or the lowest point of the truck, so that the platform can not only adapt to vehicles with different cargo heights, but also can gradually lower its own height as the cargo height decreases, ensuring that there is a better receiving point throughout the unloading cycle, thereby avoiding unloading errors and improving the unloading effect.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0056] Reference Figures 1 to 18 As shown, a method for transferring an automatic loading and unloading platform includes the following steps:

[0057] S1: Install a movable frame 201 and a power system 102 on the mobile chassis, install a transmission frame 301 inside the movable frame 201, and install a suction structure 20 and a central material guiding mechanism 30 on the side of the transmission frame 301 close to the pickup area;

[0058] S2: Move the entire mobile chassis 1 to the entrance of the truck compartment, reset the power system 102, lower the transmission frame 301 to its lowest position, and reset the adsorption structure 20 and the central material guide mechanism 30 so that the adsorption structure 20 and the central material guide mechanism 30 are flush with the width of the mounting frame 10;

[0059] S3: Obtain the overall width of the box and the area of the cargo inside the box through the visual system, and send the acquired data to the power system 102, the adsorption structure 20, and the central material guiding mechanism 30;

[0060] S4: driving the running wheels 101 of the mobile chassis 1 according to the data fed back by the visual system, so that the mobile chassis 1 is positioned in front of the cargo surface;

[0061] S5: Based on the data fed back by the vision system, the transport rack 301 is lifted to the corresponding position of the goods, the width of the adsorption structure 20 and the central material guide mechanism 30 are adjusted, and the adsorption structure 20 and the central material guide mechanism 30 are pushed out by the driving mechanism 50 to adsorb the goods, and the goods are transported to the rear end through the transport rack 301;

[0062] S6: Gradually adjust the height of the transport rack 301 through the power system 102 until the cargo height given by the visual system is 0, and it is determined that the cargo unloading on this side is completed, and the mobile chassis 1 is fed forward;

[0063] S7: Repeat S5 to S6 until the visual system determines that there is no cargo in the current carriage, and the mobile chassis 1 exits the carriage.

[0064] Furthermore, the S3 specifically includes:

[0065] S31: Obtain the length and width of the truck compartment;

[0066] S32: Obtain the length and width of the entire surface of the goods;

[0067] S33: Obtain the quantity and height of a single row of goods.

[0068] After obtaining the length of the carriage, it is convenient to adjust the mobile chassis 1 to determine its own position, so as to promote the mobile chassis 1 to reach an accurate and centered position. The length and width of the entire surface of the goods are convenient for the adsorption structure 20 and the centered material guiding mechanism 30 to determine whether they need to be expanded. The number of single-row goods is convenient for determining the number of adsorption structures 20 to be opened to avoid empty suction, and the height of a single-row goods is convenient for the conveyor rack to determine the height each time it is adjusted.

[0069] Furthermore, the moving of the transport rack 301 to the bottom position of the topmost box according to the data fed back by the visual system specifically includes: raising the end of the transport rack 301 close to the cargo pickup through the front end of the power system 102, so that the transport rack 301 reaches the bottom end of the topmost cargo, thereby enabling unloading from the topmost, and then unloading each layer of cargo separately by using a layer-by-layer degradation method.

[0070] Furthermore, if the height of the topmost cargo is higher than the height of the already raised conveyor frame 301, the rear end of the power system 102 is used to raise the end of the conveyor frame 301 away from the cargo pickup, so that the already raised conveyor frame 301 can be raised a second time, thereby facilitating entry into a small-volume carriage while being able to be raised a second time to adapt to a large-volume carriage.

[0071] Furthermore, the adjustment of the width of the adsorption structure 20 and the central material guiding mechanism 30 specifically includes: identifying the width of a single row of goods based on the width of the entire surface of the goods, and judging whether the width of the single row of goods exceeds the width of the mounting frame 10; if the width of the single row of goods is within the width range of the mounting frame 10, the adsorption structure 20 is directly pushed out for adsorption; if the width of the single row of goods exceeds the width of the mounting frame 10, the adsorption structure 20 and the central material guiding mechanism 30 are simultaneously expanded outward until they are equal in width to the width of the goods.

[0072] The transfer method of the present invention is realized by a cargo handling mechanism, which includes: a mounting frame 10 for installing a driving structure and a material receiving structure; an adsorption structure 20 movably mounted on the driving structure, the adsorption structure 20 includes a wire slot box 21 connected to the driving structure, a plurality of solenoid valves are arranged in the wire slot box 21, and all the solenoid valves are connected to a vacuum pump through an air pipeline, a movable suction cup group 23 is provided on the side of the wire slot box 21 close to the cargo pickup, and a compensation group 24 is also provided on the side of the wire slot box 21 close to the cargo pickup. When the width of the cargo is greater than the length of the suction cup group 23, the compensation group 24 extends in a direction away from the suction cup group 23 to the side close to the cargo. The width is equal; a central material guiding mechanism 30 is located on the inner side of the mounting frame 10, and the central material guiding mechanism 30 includes a central transmission structure 31 arranged in the middle of the inner side of the mounting frame 10, and the central transmission structure 31 is adjacent to the transmission frame away from the side of the pickup, and lateral material guiding structures 32 are installed on both sides of the central transmission structure 31. After the suction cup group 23 or the compensation group 24 adsorbs the goods to the lateral material guiding structure 32, it moves toward the central transmission structure 31 through the lateral material guiding structure 32 and moves to the transmission frame through the central transmission structure 31. The lateral material guiding structure 32 includes a first state and a second state. When the width of the goods is equal to the length of the mounting frame 10, the The lateral guide structure 32 is in the first state. When the width of the cargo exceeds the length of the mounting frame 10, the lateral guide structure 32 extends laterally to the second state. The driving structure 50 includes a transverse driving component 51 and a longitudinal driving component 52 connected to the wire trough box 21. The transverse driving component 51 pushes the adsorption structure 20 laterally and changes the height through the longitudinal driving component 52. A mobile chassis 1 is provided with a plurality of walking wheels 101 at the bottom of the mobile chassis 1, and a power system 102 is provided on the inner side of the mobile chassis 1; a movable frame 2 is movably provided on the top of the mobile chassis 1, and the movable frame 2 includes a movable frame that moves relative to the mobile chassis 1. 201, the movable frame 201 is provided with a driven structure 202 connected to the power system 102; an adjustable transmission component 3 with adjustable height, including a transmission rack 301 connected to the mounting frame 10, the inner side of the transmission rack 301 is provided with a plurality of transmission surfaces for transmitting goods to the rear end, and the outer side of the transmission rack 301 is movably installed with a plurality of connecting members 302, and the plurality of connecting members 302 are locked on a plurality of belts 303 on the driven structure 202. When the driven structure 202 drives the belt 303 to move up and down, the belt 303 drives the connecting member 302 and the transmission rack 301 connected to the connecting member 302 to lift or lower.

[0073] 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 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 driven to lift the transmission frame 301 to the corresponding position of the cargo, and adjust the width of the compensation group 24 and the push-out distance of the compensation power source 3213 according to the width of the cargo, and then start unloading, and continuously adjust the height of the transmission frame 301 during the unloading process.

[0074] Some existing transfer equipment can also go deep into the compartment of the truck to transfer goods, but since 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 a second unloading after re-identification on the outside. This not only wastes a lot of time, but also the secondary alignment is prone to errors. Therefore, the present invention provides an adsorption structure 20, which can not only have the adsorption and transfer function of the original suction cup group 23, but also add a compensation group 24. 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, allowing the suction cup group 23 to adsorb the goods in the normal area, and the compensation group 24 to adsorb the goods beyond the normal area, so that the entire transfer device can cover the entire surface of the goods without secondary adjustment. The transfer structure can gradually go deeper into the compartment after only one adjustment, and the overall transfer efficiency is improved. At the same time, the transfer quality is also improved, and the corresponding area can be identified and covered more accurately.

[0075] 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 be a problem when receiving goods. Therefore, the compensation group 24 of this embodiment includes a sub-rail 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-rail 241. The suction cup compensation seat 242 is provided with a number of suction cups identical to the suction cup group 23, and the top of the suction cup compensation seat 242 is locked with a rack 243, and the rack 243 is driven by a motor with a gear. When the motor is activated, it drives the suction cup compensation seat 242 to move inward or outward along the sub-rail 241. The compensation group 24 is provided with a separate sub-rail 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.

[0076] In the existing transfer equipment, the goods are mostly taken off by the adsorption end, and then placed on the conveyor belt for transportation. The steps and actions of the adsorption end need to be edited in a complex manner. The adsorption end needs to act repeatedly, and the efficiency of the transfer is very slow. Therefore, the present invention adds a central guide mechanism 30. The adsorption structure 20 can adsorb a whole row of goods at the same time and place them on the central guide mechanism 30. The goods in the middle are first transferred to the rear end transfer rack through the central transmission structure 31, and the side guide structure 32 is used to transfer the side goods to the position of the central transmission structure 31. The cargo is transported through the middle transmission structure 31 to the rear end again, and the adsorption structure 20 can start adsorption again during the action of the lateral guide structure 32, so that only one adsorption action is needed to complete the transfer of the entire row of cargo, and the overall transportation efficiency is greatly improved. The action amplitude of the adsorption structure 20 is small, the cycle is fast, and the precision is high. When 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 undertake carriages with larger lateral areas, with high adaptability.

[0077] 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 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, and 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 from a relatively middle position, and in order to avoid slipping, a push buckle 313 is also provided 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.

[0078] Not all guide rollers in the lateral guide structure 32 are powered, otherwise the overall energy cost would be high. Therefore, the lateral guide structure 32 of this embodiment includes a plurality of lateral guide rollers 321 slidingly arranged on both sides of the front end of the mounting frame 10. At least one power roller 322 is arranged between the lateral guide rollers 321. The power rollers 322 and the lateral guide rollers 321 and the lateral guide rollers 321 are connected by movable adjustment members 323. At least one compensation strip 324 is connected between the mounting seats on the outer sides of the shaft heads at both ends of the power rollers 322 or the lateral guide rollers 321. The material structure 32 is provided with at least one power roller 322 to assist multiple side guide rollers 321, and then the power roller 322 and the side guide roller 321 are linked by means of a movable adjustment member 323, so that the side guide roller 321 is also powered, so that the goods can move faster and more steadily when moving toward the middle. In order to avoid the problem of excessive gaps between the side guide rollers 321 and between the side guide rollers 321 and the power roller 322, which may cause the goods to slip, an elastic compensation strip 324 is also provided on the power roller 322 or the side guide roller 321, so that the goods have a larger contact area with the transfer device.

[0079] It is mentioned above that the lateral material guide structure 32 is adjustable, so the distance between the power roller 322 and the lateral guide roller 321 will change to a certain extent. If a traditional belt or chain is used, it is easy to be too tight or too loose to provide power. Therefore, the movable adjustment member 323 of this embodiment includes a hinge plate 3231 rotatably connected to the shaft head of the power roller 322 or the lateral guide roller 321, and the two adjacent hinge plates 3231 are connected by a movable wheel 3232. The movable wheel 3232 is connected to the shaft head of the power roller 322 or the lateral guide roller 321 through a belt. The belt is connected by two hinge plates 3231 and a movable wheel 3232. The angle between the two hinge plates 3231 can be automatically adjusted according to the gap between the power roller 322 and the lateral guide roller 321, so that the belt can always be taut and provide a transmission effect for the lateral guide roller 321 and the power roller 322.

[0080] Although the above-mentioned setting allows the spacing between the lateral guide roller 321 and the power roller 322 to be stably adjusted, the guide rollers arranged too long will reduce the stability of the distal guide roller. Therefore, the lateral guide roller 321 of this embodiment is divided into an inner guide roller and a compensation guide roller. The inner guide roller is slidably mounted on an inner guide rail 3211, and the compensation guide roller is mounted on a compensation guide frame 3212. A compensation power source 3213 is locked to the bottom of the mounting frame 10, and the output end of the compensation power source 3213 is connected to the bottom of the compensation guide frame 3212. When all When the total length of the inner guide rollers is less than the width of the cargo, the compensation power source 3213 pushes out the compensation guide frame 3212, so that the length of the inner guide rollers and the compensation guide rollers is greater than or greater than the width of the cargo, and the lateral guide rollers 321 are divided into two areas of guide rollers, and two guide structures, the inner guide rail 3211 and the compensation guide frame 3212, are separately provided. The guide rollers at the proximal end are arranged on the inner guide rail 3211, and the guide rollers at the distal end are arranged on the compensation guide frame 3212, and then driven by the compensation power source 3213, thereby ensuring that both the proximal end and the distal end can provide stable support for the cargo.

[0081] When the goods move toward the transmission frame, in order to allow them to move more toward the middle position and avoid being misplaced and stuck on the middle transmission structure 31, a guide bar 3214 is provided at the upper end of the compensation guide frame 3212. The guide bar 3214 is an L-shaped structure. The guide bar 3214 is provided with an assist roller 3215 on the side close to the middle transmission structure 31, so that the goods slightly close to the side can be guided by the guide bar 3214, and some corners of the goods that are not in contact with the middle transmission structure 31 can also be transported to the rear end by the assist roller 3215.

[0082] In order to improve the smoothness of the goods being adsorbed and transferred during unloading, the mounting frame 10 is provided with a feeding guide roller 11 on the side close to the goods picking up, and the compensation guide roller is provided with a compensation guide roller 12 on the mounting seat of the shaft head close to the goods picking up side. Even when the goods are in contact with the mounting frame 10, they can be guided by the feeding guide roller 11 and the compensation guide roller 12.

[0083] Since the entire adsorption structure 20 needs to move back and forth frequently when sucking in and unloading goods, it is difficult to arrange the air pipeline and several wires, and it is difficult to set up wire troughs. Therefore, this embodiment adds a movable wire clamp 40, and the movable wire clamp 40 includes a first fixed seat 41 locked on the wire trough box 21, and a second fixed seat 42 locked at the rear end of the mounting frame 10. A wire trough 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 trough accommodating frame 43 is guided by a guide rail 44, so that the air pipeline and several wires can be arranged in the wire trough accommodating frame 43, these lines are restrained, and are always in a limited route under the limit of the guide rail 44, making the line more stable.

[0084] When the line is accommodated in the wire trough accommodating frame 43, it will extend or shorten as the wire trough accommodating frame 43 changes. Specifically, the wire trough accommodating frame 43 includes a first accommodating block 431, a second accommodating block 432, a third accommodating block 433, and a fourth accommodating block 434, which are connected in sequence head to tail. The first accommodating block 431, the second accommodating block 432, the third accommodating block 433, and the fourth accommodating block 434 are hinged. The hinged position of the second accommodating block 432 and the third accommodating block 433 is slidably connected to the guide rail 44 through a slider 435. The first accommodating block 431 is close to the second accommodating block 432. A first limit button 436 is provided on the side, a second limit button 437 is provided on the side of the second accommodating block 432 close to the third accommodating block 433, and a third limit button 438 is provided on the side of the fourth accommodating block 434 close to the third accommodating block 433. The hollow first accommodating block 431, the second accommodating block 432, the third accommodating block 433, and the fourth accommodating block 434 will move when the adsorption structure 20 moves. After the adsorption structure 20 is fully retracted, the position of the accommodating blocks can be regulated by the first limit button 436, the second limit button 437, and the third limit button 438, thereby avoiding collision between the accommodating blocks.

[0085] After the central material guiding 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 distributed horizontally, but stacked together. Therefore, some goods distributed at higher positions are difficult to remove. If the overall frame is adjusted directly, not only the adjustment speed is slow, but the overall movement amplitude is also large. Therefore, the present invention sets a driving structure 50, which can first change the extension or retraction state of the adsorption structure 20 through the transverse driving component 51, so that it can complete the process of moving the goods from the box to the central material guiding mechanism 30, and secondly, push out or retract the longitudinal driving component 52 to make the adsorption structure 20 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. The position change of a small area can be completed without large-scale adjustment of the frame structure, thereby improving the practicality of the present invention.

[0086] During the use of the driving structure 50, it is movably arranged on the mounting frame 10. In order to better distinguish the installation position of the centering material guiding mechanism 30 and the driving structure 50, the mounting frame 10 includes a front frame 13 for accommodating the centering material guiding mechanism 30, and the end of the front frame 13 away from the incoming goods is connected to a lower mounting frame 15, and the upper end of the lower mounting frame 15 is connected to the upper mounting frame 14. The transverse driving assembly 51 includes an upper hinge seat 511 locked on the upper mounting frame 14, and a telescopic push rod motor 512 is hinged on the upper hinge seat 511. The other end of the telescopic push rod motor 512 is movably mounted on the back side of the line trough box 21. The longitudinal driving assembly 52 includes a first lower hinge seat 521 arranged on the inner side of the lower mounting frame 15. The line trough box 2 1 is provided with a second lower articulated seat 523 on the back side, and a reversing push rod motor 522 is provided between the first lower articulated seat 521 and the second lower articulated seat 523. When the adsorption structure 20 is in use, the material is taken out and unloaded again by extending and contracting the telescopic push rod motor 512. When it is necessary to adsorb the goods on a higher layer, the wire trough box 21 is pushed out by the reversing push rod motor 522 to lift the wire trough box 21 upward. At the same time, since the telescopic push rod motor 512 is connected to the wire trough box 21, the telescopic push rod motor 512 must also be set to a hinged state. The driving structure 50 is set to multi-dimensional operation and combined with the high adaptability of the adsorption structure 20 and the central material guiding mechanism 30, the entire batch transfer equipment can adapt to most trucks and containers on the market, thereby improving the applicable scenarios of this embodiment.

[0087] Existing cargo needs to change its own height according to the height of the cargo during the unloading stage in order to achieve the effect of fast loading and unloading. However, the heights of different trucks are different, and the heights of the cargo are different. If real-time adjustments are made every time the cargo arrives, it will take a lot of time to unload separately. Therefore, the cargo transfer platform provided by the present invention can allow the platform to directly enter the interior of the truck through the mobile chassis 1, and an adjustable transmission component 3 is also provided on the mobile chassis 1, which can allow the transmission frame 301 to change its own height through the power system 102 and the driven structure 202, so that the transmission frame 301 can reach the highest point or the lowest point of the truck, so that the platform can not only adapt to vehicles with different cargo heights, but also can gradually lower its own height as the cargo height decreases, ensuring that there is a better receiving point throughout the unloading cycle, thereby avoiding unloading errors and improving the unloading effect.

[0088] During the process of raising or lowering the transmission frame 301, the transmission frame 301 cannot be adjusted in situ, but needs to undergo slight deformation. Therefore, the movable base frame 1 in this embodiment includes a front base frame 103 and a rear base frame 104. The height of the rear base frame 104 is higher than the front base frame 103. Guide rails 105 are provided on both sides of the top of the front base frame 103 and the rear base frame 104. The movable frame 2 slides with the guide rails 105. A vacuum pump is provided in the front base frame 103. The movable frame 2 is movable. Its movement is derived from the cooperation with the guide rails 105 on the movable base frame 1, so that the position of the movable frame 2 itself can be changed, thereby making it less likely for mechanical interference to occur when the transmission frame 301 installed on the movable frame 2 changes height. 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 base frame 103 with a lower height and larger space.

[0089] Since the vacuum pump and other power structures need to be installed in 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 frame 2 and the power system 102 are also arranged in sections. 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 an excessively high vehicle bottom that increases the overall height of the platform, thereby avoiding the inability to enter some small vehicles.

[0090] The driven structure 202 is distributed on the entire movable frame 2, but since it is difficult for the front and rear ends to form a linkage, the front and rear ends are driven separately. Therefore, the power system 102 of this embodiment includes a first driving structure 1021 arranged on the front base frame 103 and a second driving structure 1022 arranged on the rear base frame 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 base frame 104. The output end of the linear driving member 1023 is connected to the movable frame 201. When the linear driving member 1023 is pushed out, the movable frame 201 moves toward the end of the cargo pickup. The power system 102 has multiple driving structures, and the linear driving member 1023 for driving the movable frame 2 itself is also arranged on the movable base frame 1, so that the movement of the movable frame 2 does not conflict with the movable base frame 1.

[0091] The entire movable frame 201 is an integrated structure, but in order to adapt to the shape of the movable base frame 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 base frame 103, and a rear frame 2012 is provided on the rear base frame 104. The front frame 2011 and the rear frame 2012 are connected by a number of connecting arms. The lower ends of the front frame 2011 and the rear frame 2012 are provided with a slide 2013 that cooperates with the guide rail 105. The output end of the linear drive 1023 is connected to one of the connecting arms. When the linear drive 1023 is pushed out, the front frame 2011 and the rear frame 2012 move forward at the same time. In order to facilitate their movement, the front frame 2011 and the rear frame 2012 are still integrated. The linear drive 1023 only drives one end to drive the other end to move, so that the position of the entire movable frame 201 can be changed.

[0092] The driven structure 202 is the key to the mobility of the transmission frame 301. The driven structure 202 includes a front driven end 2021 and a rear driven end 2022 arranged on the slide 2013. The front driven end 2021 includes a front connecting portion 20211 connected to the first driving structure 1021. The front connecting portion 20211 is connected to the first rotary 20212 through a belt. The first rotary 20212 is connected to the second rotary 20214 through a first transmission shaft 20213. The first rotary 20212 and the second rotary 20214 are both connected to the front end belt body 303. The top of the front end belt body 303 is wound After passing through the first fixed wheel 20215, the connecting member 302 at the front end is locked on the belt body 303 and moves up and down with the belt body 303. Among them, the key to the direction-changing ability of the transmission frame 301 lies in the front driven end 2021. When the first driving structure 1021 in the front driven end 2021 rotates, the second rotary device 20214 is linked through the first transmission shaft 20213 via the first rotary device 20212 to rotate the front end belt body 303, thereby driving the connecting member 302 to move up and down, thereby realizing the change of the position of the connecting member 302, and then changing the position of the transmission frame 301 connected to the connecting member 302, and achieving real-time adjustment of the transmission height.

[0093] In order to fully ensure the movement accuracy of the belt body 303 and thus ensure the movement progress of the connecting member 302, the first circular motion device 20212 and the second circular motion device 20214 of this embodiment have the same structure and size. The first circular motion device 20212 includes a circular motion gear 202121 connected to the belt, and the circular motion gear 202121 is connected to a docking seat 202122 on the side close to the transmission shaft 20213, and the circular motion gear 202121 is connected to a matching gear 202123 on the side away from the transmission shaft 20213. A tension gear 202124 is installed on the front frame 2011, and the lower end of the belt body 303 is connected to a On the adjusting gear 202125, the mating gear 202123, the tension gear 202124, and the adjusting gear 202125 are all connected by belts. The first revolver 20212 and the second revolver 20214 are not simply driven by gear belts, but through the coordination between the mating gear 202123, the tension gear 202124, and the adjusting gear 202125, the front end belt body 303 can move in a taut posture when moving, thereby achieving the most accurate movement accuracy, and then allowing the transmission rack 301 to reach a more accurate position, so that the goods can be caught by the transmission rack 301 after adsorption.

[0094] Different trucks have different heights, and some trucks are smaller. Therefore, if the height of the platform is set too high, it is easy for small trucks to not be able to enter. If the platform is set too low, the transmission frame 301 after displacement still cannot reach the highest height of the large truck. Therefore, the rear driven end 2022 of this embodiment includes a rear connecting portion 20221 connected to the second driving structure 1022, and the rear connecting portion 20221 is connected to the third rotary 20222 through a belt. The third rotary 20222 is connected to the fourth rotary 20224 through the second transmission shaft 20223. The third rotary 20222 and the fourth rotary 20224 are both connected The top of the belt body 303 at the rear end is wound around the second fixed wheel 20225, and the connecting piece 302 at the rear end is locked on the belt body 303 and moves up and down with the belt body 303. A rear driven end 2022 is provided at the position of the rear chassis 104. The position of the belt body 303 at the rear end can be changed by the rear driven end 2022, thereby driving the height of the connecting piece 302 at the rear end, and then the height of the transmission frame 301 that has been changed can be raised again, so that the height setting of the platform can be changed, and then the height of the entire transmission frame 301 can be raised to a position that is flush with the highest height of the large truck by using the secondary lifting.

[0095] Although the transmission rack 301 can achieve the effect of transmitting goods, it does not have the effect of limiting and guiding the goods, and the goods are easy to slide or fall from the side. Therefore, the upper end of the transmission rack 301 of the embodiment is movably installed with a side fence 304, and the side fence 304 includes a plurality of connecting rods 3041 hinged on the outside of the transmission rack 301. The top of the connecting rod 3041 is hingedly installed with a side fence 3042. The side of the side fence 3042 close to the pickup end is hinged to the mounting frame 10. The side fence 3042 is hinged to the mounting frame 10. The side of 042 away from the pickup end is hinged to the outer side of the transmission frame 301, and a side rail frame 304 is set at the position of the transmission frame 301. The side rail frame 304 is used to limit the side of the transmission frame 301. In order to adapt to the position change of the transmission frame 301, the side rail frame 304 is not a fixed setting, but is connected to the transmission frame 301 through a movable connecting rod 3041, so that the height of the side rail frame 304 can also change during the rising and falling process of the transmission frame 301, and it is not easy to collide with other structures.

[0096] During the up and down movement of the transmission rack 301, it all depends on the cooperation between the connecting member 302 and the belt body 303. The connecting member 302 is only connected to the belt body 303, and is less guided during its movement. 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 of this embodiment, and a long track 2024 is provided on the inside of the front frame 2011 and the rear frame 2012. The connecting member 302 cooperates with the short track 3011 and the long track 2024 respectively. The short track 3011 and the long track 2024 are provided, and the movement of the connecting member 302 can be guided in two directions, so that it can return to its original position along the original track after moving, so that each movement can achieve a very precise effect.

[0097] The length of the transmission frame 301 is not enough to connect the goods to the processing equipment in the next stage. Therefore, a slave platform 305 is hinged at the end of the transmission frame 301 in this embodiment, and a fixed platform 306 is installed at the tail end of the slave platform 305. The fixed platform 306 is connected to the movable frame 2 through a fixing part 307. Among them, the slave platform 305 does not have a separate power structure and will be linked with the transmission frame 301 through a hinged relationship, while the fixed platform 306 is fixed to the movable frame 2 through fixing parts 307 such as a fixed frame and an inclined rod, and will not change its position.

[0098] In summary, through the multi-angle coordination of the adsorption structure 20, the central material guiding mechanism 30, the driving structure 50, the movable frame 2 and the adjustable transmission component 3, the entire cargo handling mechanism can be adapted to most carriages on the market, thereby making the application range of the present invention extremely large and the adaptability extremely high.

[0099] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
