Description

Technical Field

[0001] The present invention relates to a palletizer, in particular to an auxiliary leveling palletizing device and an automatic palletizing system. Background Art

[0002] A palletizer is a device that automatically stacks single boards of the same specification into neat stacks. Existing single board palletizers consist of a conveyor line and a stacking chamber. The stacking chamber is located at the end of the conveyor line. The conveyor line transports cut or processed single boards with regular shapes to the stacking chamber. Once the single boards reach the end of the conveyor line, they enter the stacking chamber and are placed on receiving rollers. The receiving rollers swing downward, and the boards naturally fall under the action of gravity, gradually stacking one by one to form a stack.

[0003] Generally, the receiving roller is installed on the rotating shaft, and multiple rollers are arranged at equal distances or directly form a drum to ensure that the plate can roll on the roller or drum when entering the stacking chamber to reduce the wear of the plate.

[0004] However, when it is necessary to lower the plate, a placement space for the downward swing of the rotating shaft needs to be reserved between the plate and the stacking position. Therefore, there is a certain downward stroke between the plate and the placement position. When multiple rollers are used, the rotation direction of the rollers needs to match the feeding of the plate, resulting in the rotation direction of the rollers being perpendicular to the lowering direction of the plate. During the lowering process of the plate, it is easy for the plate to move along the rotation direction of the rollers, especially for special-shaped plates. Since the center of gravity of the special-shaped plates is not in the center position, the plate is more likely to shift, resulting in poor stacking neatness. When multiple rollers are used, when the rotating shaft swings downward, if the support surface of the roller and the axis of the rotating shaft are not in the same horizontal plane, the plate will move relative to the axial direction of the rotating shaft and then move in the opposite direction, causing the gap between the plate and the roller to be stuck, causing damage to the plate.

When the rotating shaft rotates, it drives the receiving wheel conveying component to deflect synchronously to perform the unloading action. The conveying direction of the conveying component is perpendicular to the feeding direction.

[0054] Various exemplary embodiments, features, and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0055] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0056] In addition, numerous specific details are provided in the following specific examples to better illustrate the present application. Those skilled in the art will appreciate that the present application can be practiced without certain specific details. In some instances, methods, means, and components well known to those skilled in the art are not described in detail in order to highlight the main purpose of the present application.

[0057] See also Figures 1-8In an embodiment of the present invention, an auxiliary flattening stacking device includes a frame 1 and two receiving mechanisms 3 mounted on the frame 1 and symmetrically arranged along the feeding direction. The frame 1 is further provided with a feed roller group 6 along the feeding direction for conveying the plates to be stacked to the receiving mechanisms 3, wherein:

[0058] The receiving mechanism 3 includes a receiving beam 301, a rotating shaft 305 rotatably mounted on the receiving beam 301, and a telescopic driving member mounted on the receiving beam 301 and used to drive the rotating shaft 305 to rotate. Multiple groups of receiving wheels are rotatably mounted on the rotating shaft 305. The receiving wheels include a receiving shaft 306 rotatably mounted on the rotating shaft 305 and multiple rollers 307 mounted on the receiving shaft 306. The supporting surfaces of the multiple rollers 307 are on the same horizontal plane as the supporting surface of the feed roller group 6.

[0059] A discharge mechanism 4 is mounted on the rotating shaft 305, wherein:

[0060] The unloading mechanism 4 includes a receiving plate 402 and multiple conveying assemblies mounted on the receiving plate 402. The receiving plate 402 is driven by at least one second cylinder 401 mounted on the rotating shaft 305 to perform a lifting action to raise the conveying surface of the conveying assembly to a position above the receiving surface of the receiving wheel or lower it to a position below the receiving surface of the receiving wheel.

[0061] It also includes a driving unit for driving the conveying assembly to rotate. When the rotating shaft 305 rotates downward, the driving unit drives the conveying assembly to perform forward and reverse motions in sequence.

[0062] In this embodiment, after the plates to be stacked are moved onto the receiving mechanism 3, the second cylinder 401 drives the receiving plate 402 to move upward, so as to drive the multiple groups of conveying components to be lifted, so that the plates are separated from the receiving mechanism 3, and then the telescopic driving member drives the rotating shaft 305 to rotate. When the rotating shaft 305 rotates, it drives the receiving wheel conveying component to deflect synchronously and perform the unloading action. The conveying direction of the conveying component is perpendicular to the feeding direction. When the plates are on the conveying component and the conveying component performs the unloading action, the conveying component follows the movement of the plates under the action of the driving unit and performs adaptive adjustment, reducing the problem of the plates moving relative to the conveying component causing the unloading offset. It can effectively eliminate the problem of the plates being offset relative to the rolling direction of the receiving wheel or being stuck on the receiving wheel during the unloading process due to the rolling direction of the receiving wheel being perpendicular to the unloading direction, thereby realizing the precise unloading of the plates. Especially for the stacking of special-shaped plates, it can effectively eliminate the problem of the plates rolling easily relative to the receiving wheel due to the offset of the center of gravity.

[0063] It should be noted that the plurality of conveying components are arranged at intervals between two adjacent receiving wheels to ensure that when the plate is fed to the receiving mechanism 3 , the conveying components do not interfere with the conveying of the plate.

[0064] See also Figure 14 , define the position where the conveying component contacts the end of the plate as A, the position where the conveying component contacts the end of the plate after the conveying component rotates a certain angle (the front end of the movement) as B, and the position where the conveying component contacts the end of the plate after the conveying component rotates a larger angle (the back end of the movement) as C. Taking the vertical plane where position A is located as the reference plane, position B is located on the left side of the reference plane, and position C is located on the right side of the reference plane. That is to say, when the conveying component swings downward following the rotating shaft 305, the plate will move a certain distance relative to the conveying component (the conveying component rotates forward), and then the plate moves in the opposite direction relative to the conveying component (the conveying component rotates forward) during the process of the conveying component continuing to swing downward. Therefore, in this embodiment, the driving unit is set to drive the conveying component to perform forward and reverse motions in succession, so that the plate will not change its relative position relative to the conveying component, ensuring that the plate can be placed and stacked more accurately.

[0065] Further, see Figure 4-Figure 8 The conveying assembly includes a support frame 404 that slides radially along the rotating shaft 305 and two driving pulleys 407 rotatably mounted on the support frame 404. The two driving pulleys 407 are equipped with a conveyor belt 406, and one of the driving pulleys 407 is driven to rotate by the driving unit.

[0066] Exemplarily, in one embodiment, the driving unit includes a driving shaft 403 that passes through multiple support frames 404 and is rotatably connected to the support frames 404, and the driving shaft 403 is rotatably connected to the driving pulley 407 through a first transmission belt 408; and also includes a second driving source 410, and the output shaft of the second driving source 410 is rotatably connected to the driving shaft 403 through a second transmission belt 409.

[0067] It should be noted that gear teeth are formed on both sides of the driving pulley 407 , and a toothed portion meshing with the gear teeth is provided on the inner side of the conveyor belt 406 , thereby eliminating the problem of relative sliding between the conveyor belt 406 and the driving pulley 407 .

[0068] A support plate 405 is also fixed on the support frame 404 , and the support plate 405 is used to support the conveyor belt 406 to prevent the conveyor belt 406 from being deformed due to stress.

[0069] In this embodiment, the second driving source 410 is set to drive the driving shaft 403 to rotate through the second transmission belt 409, and the driving shaft 403 drives the driving pulley 407 to rotate through the first transmission belt 408, thereby realizing the driving rotation of the conveyor belt 406, wherein the driving pulleys 407 in multiple conveying components are connected to the driving shaft 403 through the first transmission belt 408 to achieve the synchronization of the movement of multiple conveying components, ensuring that the conveyor belt 406 on each conveying component can move at the same speed and direction, and preventing the plate from being subjected to different forces relative to different conveyor belts 406, causing the plate to shift.

[0070] At the same time, in order to further prevent the plate from being displaced relative to the conveyor belt 406, a friction surface is formed on the contact surface between the conveyor belt 406 and the plate, and the friction surface includes but is not limited to rubber.

[0071] It should be noted that at least one guide frame 411 is formed on the support frame 404. The guide frame 411 passes through the guide groove 308 formed on the rotating shaft 305 and can slide relative to the guide groove 308, thereby ensuring the stability of the connection between the support frame 404 and the rotating shaft 305, and ensuring that when the rotating shaft 305 rotates, it can drive the support frame 404 and the entire body installed on the support frame 404 to rotate synchronously.

[0072] See also Figure 4 The telescopic driving member includes at least one first cylinder 302 installed on the supporting beam 301, and the movable end of the first cylinder 302 is hinged with a connecting rod 303; it also includes a fixing frame 304 fixed on the rotating shaft 305, and the end of the connecting rod 303 away from the first cylinder 302 is hinged to the end of the fixing frame 304 away from the rotating shaft 305.

[0073] Preferably, two first cylinders 302 are provided, and are respectively located at the two ends of the supporting beam 301. When the first cylinder 302 is telescopically moved, the rotating shaft 305 is driven to rotate through the action of the connecting rod 303 and the fixed frame 304, so as to realize the downward swing of the support frame 404 and the overall structure installed on the support frame 404 to meet the material discharge requirements.

[0074] Further, see Figure 1-Figure 3 The two supporting beams 301 of the supporting mechanism 3 are slidably installed on the frame 1 and the distance between the two supporting beams 301 is adjusted by the adjusting mechanism 2 installed on the frame 1, wherein the adjusting mechanism 2 includes a crossbeam 201 fixed on the frame 1 and perpendicular to the feeding direction, and a screw rod 203 is symmetrically installed on the crossbeam 201 for rotation, and a wire sleeve 204 fixed to the supporting beam 301 is threadedly connected on the screw rod 203, and the screw rod 203 is driven to rotate by a first driving source 202 installed on the crossbeam 201.

[0075] The two ends of the receiving beam 301 are fixed with a first slider 205, and the first slider 205 is slidably connected to the first slide rail 206 installed on the frame 1. When the first driving source 202 drives the screw rod 203 to rotate, the receiving beam 301 and the whole installed on the receiving beam 301 are driven by the action of the wire sleeve 204 to move in a direction perpendicular to the feeding direction, thereby realizing the distance adjustment between the two receiving beams 301 to achieve the receiving and stacking of plates of different sizes, further improving the adaptability and flexibility of the equipment. In addition, the sliding connection method of the first slider 205 and the first slide rail 206 ensures the stability and accuracy of the receiving beam 301 during the movement, and avoids the occurrence of shaking or offset.

[0076] See also Figure 1 、 Figures 9-13 The frame 1 is also provided with four groups of beating mechanisms 5 that can perform two-dimensional position transformation in the horizontal plane, wherein the beating directions of two groups of the beating mechanisms 5 are toward the feeding direction, and the beating directions of the other two groups of the beating mechanisms 5 are perpendicular to the feeding direction.

[0077] Based on the feeding direction, it is defined as follows: the two groups of beating mechanisms 5 with beating directions facing the feeding direction are horizontal beating parts, and the two groups of beating mechanisms 5 with beating directions perpendicular to the feeding direction are left beating parts and right beating parts respectively, thereby realizing multi-directional beating of the stacked plates, so that the plates are stacked neatly.

[0078] For example, one implementation method is shown in Figure 11-13 The beating mechanism 5 includes a support beam 501 slidably mounted on the frame 1, and a beating member is installed at one end of the support beam 501; a first adjusting member is used to drive the support beam 501 to move in a direction parallel to the feeding direction; and a second adjusting member is used to drive the support beam 501 to move in a direction perpendicular to the feeding direction.

[0079] The position of the beating member is adjusted by the first adjusting member and the second adjusting member, so as to realize multi-directional and multi-position beating processing of the stacked plates, effectively improving the neatness of the stacking of the plates. Furthermore, the beating member includes a third cylinder 502 fixed on the support beam 501, and the movable end of the third cylinder 502 is equipped with a beating plate 503. Preferably, the beating surface of the beating plate 503 is made of rubber material. The beating surface of the rubber material not only has good elasticity, but can also provide appropriate buffering when beating the plates to avoid damage to the plates. During the beating process, the third cylinder 502 drives the beating plate 503 to perform a fast and powerful beating action to ensure that the plates can be quickly and evenly subjected to the beating force, thereby achieving an ideal stacking effect to achieve the role of auxiliary leveling.

[0080] In this embodiment, the flapping mechanism 5 is provided with four groups to form four flapping positions. At the same time, each flapping position can be adjusted in the X and Y directions. Different flapping positions can be adjusted according to the shape of the material, thereby improving the neatness of material stacking.

[0081] For ease of understanding, the feeding direction is defined as the longitudinal direction, and the direction perpendicular to the feeding direction is defined as the transverse direction.

[0082] The first adjusting member described above includes a mounting frame 504 slidably mounted on the frame 1, and the support beam 501 is slidably mounted on the mounting frame 504; it also includes a fourth driving source 508 mounted on the mounting frame 504, and the movable end of the fourth driving source 508 is fixed with a first gear 511, and the first gear 511 is engaged with a second gear plate 509 mounted on the frame 1.

[0083] The fourth driving source 508 drives the first gear 511 to rotate, thereby cooperating with the second tooth plate 509 to realize horizontal movement of the mounting frame 504 along the feeding direction (longitudinal adjustment) to change the position of the beating plate 503 and realize beating of plates at different positions.

[0084] It should be noted that a second slider 510 is installed on the mounting frame 504, and the second slider 510 is slidably connected to a third slide rail (not shown in the figure) installed on the rack 1 to ensure the stability and accuracy of the mounting frame 504 during movement.

[0085] The second adjusting member includes a third driving source 507 mounted on the mounting frame 504 . A second gear 512 is fixed to the movable end of the third driving source 507 . The second gear 512 is engaged with a first gear plate 506 fixed on the support beam 501 .

[0086] The third driving source 507 drives the second gear 512 to rotate to cooperate with the first tooth plate 506 to achieve lateral adjustment of the support beam 501, so as to change the position of the beating plate 503 and achieve beating of plates at different positions.

[0087] It should be noted that a third slider (not shown in the figure) is also provided on the mounting frame 504, and the third slider is slidably connected to the second slide rail 505 installed on the support beam 501 to ensure the stability and accuracy of the support beam 501 relative to the mounting frame 504 during movement.

[0088] The horizontal beating member, the left beating member and the right beating member described above have the same structure, and only the setting direction of the third cylinder 502 is different. Therefore, this embodiment will not elaborate on this.

[0089] The first driving source 202 , the second driving source 410 , the third driving source 507 and the fourth driving source 508 mentioned above are all servo motors and reducers connected to the output shafts of the servo motors.

[0090] As another embodiment of the present invention, an automatic palletizing system is provided, comprising the above-mentioned auxiliary leveling palletizing device.

[0091] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
