Description

Technical Field

[0001] This utility model relates to a cargo transfer structure, and in particular to a highly adaptable adsorption device. Background Technology

[0002] In the logistics industry, loading and unloading are the most labor-intensive and costly parts. There are various ways to load goods. Some are transported by placing them on pallets and transporting them directly along with the pallets. Some are transported directly by using suction cups. Some are even still transported manually, from the entrance of the vehicle or the side opening of the vehicle.

[0003] Traditional mechanical handling methods, such as robotic palletizing and traveling gantry palletizing, require not only moving the truck to the designated location but also pre-adjusting the length or other parameters of the transfer equipment according to the truck's dimensions. This involves numerous preliminary steps. Some existing equipment allows the transfer equipment to directly enter the truck's interior, thereby reducing the number of preliminary matching steps and improving transfer efficiency. Although this method reduces the number of pre-adjustment steps, the width of each vehicle is different. If the equipment is set too wide, it cannot adapt to narrow-diameter vehicles. If the equipment is set too narrow, it is necessary to repeatedly adjust the vehicle's position, recalibrate the position, and reconfirm the location of the goods when dealing with wide-diameter vehicles, which consumes a lot of time. Utility Model Content

[0004] This invention provides a highly adaptable adsorption device that can efficiently unload goods and does not require repositioning after entering the truck, effectively solving the aforementioned problems.

[0005] This utility model is implemented as follows:

[0006] A highly adaptable adsorption device, comprising:

[0007] Mounting bracket for installing drive structure and material receiving structure;

[0008] An adsorption structure is movably mounted to a drive structure. The adsorption structure includes a cable tray box connected to the drive structure. A control component is provided inside the cable tray box. A movable suction cup assembly is provided on the side of the cable tray box near the picking-up point. A compensation assembly is also provided on the side of the cable tray box near the picking-up point. When the width of the goods is greater than the length of the suction cup assembly, the compensation assembly extends away from the suction cup assembly until it is equal to the width of the goods.

[0009] As a further improvement, the compensation group includes a secondary track set on the side of the online slot box near the picking side. A suction cup compensation seat is slidably installed on the secondary track. The suction cup compensation seat is provided with several suction cups identical to those in the suction cup group. A power component is locked to the top of the suction cup compensation seat. When the power component is activated, it drives the suction cup compensation seat to move inward or outward along the secondary track.

[0010] As a further improvement, the power component includes a rack that is driven by a geared motor. When the motor is activated, it causes the suction cup compensation seat to move inward or outward along the sub-track.

[0011] As a further improvement, the control unit includes several solenoid valves, all of which are connected to a vacuum pump via pneumatic conduits.

[0012] As a further improvement, the mounting frame is provided with a feeding guide roller on the side near the picking point, and compensation guide rollers are provided on both sides of the feeding guide roller.

[0013] The beneficial effects of this utility model are:

[0014] Existing transfer equipment can also reach into the cargo compartment of a truck to transfer goods. However, since the transfer equipment is generally not the same diameter as the cargo compartment, and the adjustable area inside the compartment is limited, the transfer equipment needs to be moved out of the compartment after unloading a portion of the area. It then needs to be re-identified from the outside before re-entering the compartment for secondary unloading. This not only wastes a lot of time, but also makes it easy for errors to occur during secondary alignment. Therefore, this utility model, through the setting of an adsorption structure, not only enables the original suction cup group to have adsorption and transfer functions, but also adds a compensation group. When the width of the goods is within 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 from the side of the adsorption structure, allowing the suction cup group to adsorb the goods in the normal area, while the compensation group adsorbs the goods in the area exceeding the normal width. This allows the entire transfer device to cover the entire surface of the goods without secondary adjustment. The transfer structure only needs one adjustment to gradually penetrate into the cargo compartment, improving the overall transfer efficiency and transfer quality, and enabling more accurate identification and coverage of the corresponding area.

[0015] When the compensation group moves laterally toward the suction cup group, it needs a stable trajectory and power; otherwise, its own stability is prone to problems when receiving goods. Therefore, the compensation group of this utility model is equipped with a separate secondary 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 to move, thereby changing the position of the suction cup compensation seat and enabling the compensation group to move laterally stably.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Reference Figures 1-6 As shown, a highly adaptable adsorption device is mounted on a transfer device, which includes: a mounting frame 10 for mounting a drive structure and a receiving tray; an adsorption structure 20 movably mounted to the drive structure, the adsorption structure 20 including a cable tray 21 connected to the drive structure, the cable tray 21 containing several solenoid valves, all of which are connected to a vacuum pump via air pipes; several sets of main tracks 22 are provided on the side of the cable tray 21 near the picking-up point, and several sets of suction cups 23 communicating with the solenoid valves are slidably mounted on the main tracks 22; a compensation group 24 is also provided on the side of the cable tray 21 near the picking-up point, when the width of the goods is greater than the length of the suction cup group 23, the compensation group 24 extends away from the suction cup group 23 until it is equal to the width of the goods; a device located on the mounting frame The central guiding mechanism 30 inside the mounting frame 10 includes a central transmission structure 31 located in the middle of the inner side of the mounting frame 10. The central transmission structure 31 is adjacent to the transmission frame away from the picking side. Lateral 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 guiding structure 32, the goods move towards the central transmission structure 31 through the lateral guiding structure 32 and are moved to the transmission frame through the central transmission structure 31. The lateral 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 lateral guiding structure 32 is in the first state. When the width of the goods exceeds the length of the mounting frame 10, the lateral guiding structure 32 extends laterally to the second state.

[0026] During the docking and unloading process, the entire loading device is installed on the front end of the mobile device, and the mobile device is then docked with the transmission frame. The adsorption structure 20 can then adsorb the goods onto the central guiding mechanism 30 to begin transfer. In this embodiment, the goods being transferred are boxes, but other goods of regular shape whose weight is within the allowable orientation of the adsorption structure 20 can also be transferred.

[0027] Existing transfer equipment can also reach into the cargo compartment of a truck to transfer goods. However, since the transfer equipment is generally not the same diameter as the cargo compartment, and the adjustable area inside the compartment is limited, the transfer equipment needs to be moved out of the compartment after unloading a portion of the area. It needs to be re-identified from the outside before re-entering the compartment for secondary unloading. This not only wastes a lot of time, but also makes it easy for errors to occur during secondary alignment. Therefore, this utility model, through the adsorption structure 20, not only enables the original suction cup group 23 to have adsorption and transfer functions, but also adds a compensation group 24. When the width of the goods is within the normal width, the compensation group 24 can increase the suction force on the basis of the adsorption structure 20, making the goods 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, while the compensation group 24 adsorbs the goods in the area exceeding the normal width. This allows the entire transfer device to cover the entire surface of the goods without secondary adjustment. The transfer structure only needs one adjustment to gradually penetrate into the cargo compartment, improving the overall transfer efficiency and transfer quality, and enabling more accurate identification and coverage of the corresponding area.

[0028] When the compensation group 24 moves laterally toward the suction cup group 23, it needs a stable trajectory and power; otherwise, its stability may be compromised when receiving goods. Therefore, in this embodiment, the compensation group 24 includes a secondary track 241 set on the side of the online slot box 21 near the receiving side. A suction cup compensation seat 242 is slidably mounted on the secondary track 241. The suction cup compensation seat 242 is provided with several suction cups identical to those in the suction cup group 23. A rack 243 is locked to the top of the suction cup compensation seat 242. The rack 243 is driven by a motor with gears. When the motor is activated, it drives the suction cup compensation seat 242 to move inward or outward along the secondary track 241. The compensation group 24 has a separate secondary 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 rack 243 fixed on the suction cup compensation seat 242 is moved by the motor-driven gears, thereby changing the position of the suction cup compensation seat 242 and enabling the compensation group 24 to move laterally stably.

[0029] In existing transfer equipment, goods are usually removed by an adsorption end and then placed on a conveyor belt for transport. The steps and actions of the adsorption end require complex editing and repeated operation, resulting in very slow transfer efficiency. Therefore, this utility model adds a central guiding mechanism 30. The adsorption structure 20 can simultaneously adsorb an entire row of goods and place them on the central guiding mechanism 30. First, the central transfer structure 31 transfers the central goods to the rear transfer frame, and the lateral guiding structure 32 guides the side goods to the central transfer structure 31. The goods are conveyed again through the central conveyor structure 31 to the rear end. During the operation of the lateral guide structure 32, the adsorption structure 20 can start adsorption again. Thus, only one adsorption action is needed to complete the transfer of the entire row of goods, greatly increasing the overall conveying efficiency. Furthermore, the adsorption structure 20 has a small range of motion, a fast cycle, and high precision. When the adsorption structure 20 can be extended, the lateral guide structure 32 in this invention can also be extended laterally to match the width extension of the adsorption structure 20, which can accommodate carriages with a larger lateral area and has high adaptability.

[0030] While the central conveying structure 31 is conveying goods to the conveyor frame, it also serves to receive goods input from the lateral guide structure 32. Therefore, the central conveying structure 31 in this embodiment includes two conveying zones within the mounting frame 10. Each conveying zone includes several central guide rollers 311. The shafts of adjacent central guide rollers 311 are connected by belts and driven by at least one drive motor. A conveyor belt 312 is also provided between two adjacent central guide rollers 311. A push buckle 313 is connected to the conveyor belt 312. When the conveyor belt 312 rotates, the push buckle 313 pushes the goods toward one side of the conveyor frame. The central conveying structure 31 not only has a conveyor belt 312 that can transport goods to the rear conveyor frame, but also has central guide rollers 311 that can center the goods, allowing the goods to be conveyed to the rear in a relatively central position. In addition, to avoid slippage, a push buckle 313 is provided on the conveyor belt 312 to push the goods, allowing customers to move from the central conveying structure 31 to the rear in a timely manner.

[0031] In the lateral guiding structure 32, not all guide rollers are powered, otherwise the overall energy cost would be high. Therefore, the lateral guiding structure 32 in this embodiment includes several lateral guide rollers 321 slidably disposed on both sides of the front end of the mounting frame 10. At least one powered roller 322 is disposed between the lateral guide rollers 321. The powered roller 322 is connected to the lateral guide rollers 321 via a movable adjusting member 323. At least one compensating strip 324 is connected between the mounting seats on the outer sides of the shaft ends of the powered roller 322 or the lateral guide roller 321. The material structure 32 is equipped with at least one power roller 322, which assists multiple side guide rollers 321. The power roller 322 and the side guide rollers 321 are connected by a movable adjusting member 323, so that the side guide rollers 321 also have power, allowing the goods to move faster and more stably towards the center. In order to avoid the problem of goods slipping due to excessive gaps between the side guide rollers 321 and between the side guide rollers 321 and the power roller 322, elastic compensation strips 324 are also provided on the power roller 322 or the side guide rollers 321 to allow the goods to have a larger contact area with the transfer device.

[0032] As mentioned above, the lateral 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 in this embodiment includes a hinge plate 3231 rotatably connected to the shaft of the power roller 322 or the lateral guide roller 321. Two adjacent hinge plates 3231 are connected by a movable wheel 3232. The movable wheel 3232 is connected to the shaft of the power roller 322 or the lateral guide roller 321 by a belt. By using two hinge plates 3231 and a movable wheel 3232 to connect the belt, the included angle of 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 between the lateral guide roller 321 and the power roller 322.

[0033] Although the above-described arrangement allows for stable adjustment of the distance between the lateral guide roller 321 and the power roller 322, excessively long guide rollers can reduce the stability of the distal guide roller. Therefore, in this embodiment, the lateral guide roller 321 is divided into an inner guide roller and a compensating guide roller. The inner guide roller is slidably mounted on an inner guide rail 3211, and the compensating guide roller is mounted on a compensating guide frame 3212. A compensating power source 3213 is locked to the bottom of the mounting frame 10, and the output end of the compensating power source 3213 is connected to the bottom of the compensating guide frame 3212. When all... When the total length of the inner guide rollers is less than the width of the goods, the compensating power source 3213 pushes out the compensating guide frame 3212, so that the length of the inner guide rollers and the compensating guide rollers is greater than or greater than the width of the goods. This divides the lateral guide rollers 321 into two regions, and provides two guiding structures: an inner guide rail 3211 and a compensating guide frame 3212. The guide rollers at the near end are set on the inner guide rail 3211, and the guide rollers at the far end are set on the compensating guide frame 3212. The compensating power source 3213 drives the rollers, thereby ensuring that both the near and far ends can provide stable support for the goods.

[0034] When goods move towards the transfer rack, in order to move them closer to the center and avoid misalignment and stagnation on the central transfer structure 31, a guide bar 3214 is provided at the upper end of the compensation guide 3212. The guide bar 3214 has an L-shaped structure, and an assist roller 3215 is provided on the side of the guide bar 3214 near the central transfer structure 31. This allows goods that are slightly closer to the side to be guided by the guide bar 3214, while goods whose corners are not in contact with the central transfer structure 31 can also be transferred to the rear end by the action of the assist roller 3215.

[0035] To improve the smoothness of cargo transfer during unloading, the mounting frame 10 is provided with an infeed guide roller 11 on the side near the picking point, and a compensation guide roller 12 is provided on the mounting seat of the shaft head near the picking point. Even when the cargo comes into contact with the mounting frame 10, it can be guided by the infeed guide roller 11 and the compensation guide roller 12.

[0036] Because the entire adsorption structure 20 needs to move back and forth frequently during adsorption and unloading, it is difficult to arrange the air pipes and several wires, and it is difficult to set up wire troughs. Therefore, this embodiment adds a movable wire clamp 40. The movable wire clamp 40 includes a first fixed seat 41 locked to the wire trough box 21 and a second fixed seat 42 locked to the rear end of the mounting frame 10. A hollow wire trough receiving frame 43 is movably installed between the first fixed seat 41 and the second fixed seat 42. The middle part of the wire trough receiving frame 43 is guided by a guide rail 44, so that the air pipes and several wires can be arranged in the wire trough receiving frame 43, which binds these lines and keeps them on a limited route under the limit of the guide rail 44, making the lines more stable.

[0037] When the cable is housed within the cable tray holder 43, it will lengthen or shorten as the cable tray holder 43 changes. Specifically, the cable tray holder 43 includes a hollow first receiving block 431, a second receiving block 432, a third receiving block 433, and a fourth receiving block 434 connected end to end in sequence. The first receiving block 431, the second receiving block 432, the third receiving block 433, and the fourth receiving block 434 are hinged together. The hinged position of the second receiving block 432 and the third receiving block 433 is slidably connected to the guide rail 44 via a slider 435. The side of the first receiving block 431 closest to the second receiving block 432... A first limiting button 436 is provided, a second limiting button 437 is provided on the side of the second receiving block 432 near the third receiving block 433, and a third limiting button 438 is provided on the side of the fourth receiving block 434 near the third receiving block 433. The hollow first receiving block 431, second receiving block 432, third receiving block 433, and fourth receiving block 434 will move along with the adsorption structure 20 when it moves. After the adsorption structure 20 is completely retracted, the positions of the receiving blocks can be regulated by the first limiting button 436, the second limiting button 437, and the third limiting button 438, thereby preventing the receiving blocks from colliding with each other.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
