Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of stamping equipment, and more particularly to a stacking system. BACKGROUND

[0002] In the field of stamping technology, a stacking vehicle is used to stack materials for subsequent stamping processes. Generally, the position of the stacked materials after stacking is adjusted manually. For example, the edge angle of the stacked materials exceeds the angle of the sheet separator, and the sheet separator cannot completely fit the edge of the stacked materials. In order to prevent affecting the sheet separation effect, the position of the stacked materials needs to be adjusted manually. For example, after the stacked materials are stacked, the stacked materials need to be rotated by 90° according to the design of the mold process before starting the production line. Although the manual adjustment method can achieve the position adjustment of the stacked materials in the related art, the manual adjustment efficiency is low, and there may be quality problems such as damage to the edge of the stacked materials. SUMMARY

[0003] The purpose of the embodiments of the application is to provide a stacking system to improve production efficiency while further reducing the risk of damage to the edge of the stacked materials and improving product yield.

[0004] To achieve the above purpose, the technical solution adopted by the application is:

[0005] A stacking system is provided, which includes a stacking vehicle and a first mechanism.

[0006] The first mechanism includes a first driving assembly and a first platform. The first platform is drivingly connected to the first driving assembly and can move linearly in a first direction under the driving of the first driving assembly. The first platform is used to dock the stacking vehicle.

[0007] The stacking vehicle includes a vehicle body and a second mechanism arranged on the vehicle body. The second mechanism includes a second driving assembly and a second platform. The second platform is drivingly connected to the second driving assembly and can rotate relative to the vehicle body under the driving of the second driving assembly. The second platform is used to place stacked materials. The rotation axis of the second platform is perpendicular to the first direction.

[0008] The first mechanism further includes a third driving assembly.

[0009] The third driving assembly is drivingly connected to the first platform and the first driving assembly. The third driving assembly is used to drive the first platform to move in the direction of the rotation axis, and to drive the first platform to move synchronously in the first direction under the driving of the first driving assembly.

[0010] In some embodiments, the first driving assembly includes a first driving machine, a driving screw, and a driving seat body.

[0011] The drive seat is driven by the drive screw, which is driven by the first drive machine and can drive the drive seat to move along the first direction under the drive of the first drive machine. The third drive assembly is disposed on the drive seat.

[0012] In some embodiments, the first drive assembly further includes a support base, the support base being provided with a linear guide rail extending along the first direction; the drive base is slidably disposed on the linear guide rail and is capable of moving along the linear guide rail under the drive of the first drive motor.

[0013] In some embodiments, the second drive assembly includes a second drive motor and meshing first and second gears;

[0014] The second gear is coaxially and drivenly connected to the second platform, and the first gear is coaxially and drivenly connected to the second drive motor, and can drive the first platform to rotate through the first gear under the drive of the second drive motor.

[0015] In some embodiments, the second platform is spaced apart from the projection of the second platform on the palletizing vehicle along the axis of rotation, and the second drive assembly is disposed in the space.

[0016] In some embodiments, the second drive motor is located within the projection of the first gear and the second gear along the axis of rotation on the palletizing vehicle.

[0017] In some embodiments, the diameter of the first gear is smaller than the diameter of the second gear.

[0018] In some embodiments, the third drive assembly includes a first hinge and a second hinge that are hinged together, and the first platform and the drive base are parallel and spaced apart.

[0019] One end of the first hinge and one end of the second hinge are respectively hinged to the first platform, and the other ends of the second hinge are respectively hinged to the drive seat. The angle between the first hinge and the second hinge is variable.

[0020] In some embodiments, the third drive assembly further includes a first telescopic member and a second telescopic member;

[0021] The fixed part of the first telescopic member is connected to the second hinge member, and the telescopic part of the first telescopic member is connected to the first hinge member; the fixed part of the second telescopic member is connected to the first hinge member, and the telescopic part of the second telescopic member is connected to the second hinge member.

[0022] The advantages of the palletizing system provided in this application are as follows:

[0023] Compared with the prior art, the palletizing system provided in this application has a first platform that is driven by a first drive assembly and can move linearly in a first direction under the drive of the first drive assembly. The first platform can dock a palletizing cart, meaning the palletizing cart can move linearly in the first direction with the first platform. The second platform is driven by a second drive assembly and can rotate relative to the palletizing cart under the drive of the second drive assembly. The second platform can hold palletized material, so the palletized material can rotate relative to the palletizing cart with the second platform and can move in the first direction with the palletizing cart.

[0024] The palletizing system can be configured to adjust the circumferential position of the first platform and its linear position in the first direction, allowing for arbitrary adjustments to both the circumferential and linear positions of the pallet. For example, adjustments to the circumferential and linear positions can be used to align the edge angle of the pallet with the angle of the sheet divider, enabling the pallet to fit the maximum number of sheet dividers. The palletizing system uses automated drive components to adjust the specific position of the pallet, reducing manual intervention and improving production efficiency compared to existing technologies. Because manual intervention is required, the risk of damage to the pallet edges is reduced, thereby improving product quality. Attached Figure Description

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] Furthermore, 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] The palletizing system provided in the embodiments of this application will now be described.

[0039] Please see Figs. 1 to 3As shown, the palletizing system provided in this application embodiment includes a palletizing cart 200 and a first mechanism 100. The first mechanism 100 includes a first drive assembly 101 and a first platform 102. The first platform 102 is tractively connected to the first drive assembly 101 and can move linearly along a first direction X under the drive of the first drive assembly 101. The first platform 102 is used to park the palletizing cart 200. The palletizing cart 200 includes a cart body 201 and a second mechanism 202 disposed on the cart body 201. The second mechanism 202 includes a second drive assembly 2021 and a second platform 2022. The second platform 2022 is tractively connected to the second drive assembly 2021 and can rotate relative to the cart body 201 under the drive of the second drive assembly 2021. The second platform 2022 is used to place the palletized material; wherein, the rotation axis Y of the second platform 2022 is perpendicular to the first direction X.

[0040] The palletizing system provided in this application embodiment includes a first platform 102 that is driven by a first drive assembly 101 and can move linearly in the first direction X under the drive of the first drive assembly 101. The first platform 102 can dock a palletizing cart 200, meaning the palletizing cart 200 can move linearly with the first platform 102 in the first direction X. A second platform 2022 is driven by a second drive assembly 2021 and can rotate relative to the body 201 of the palletizing cart 200 under the drive of the second drive assembly 2021. The second platform 2022 can hold palletized materials, so the palletized materials can rotate relative to the palletizing cart 200 with the second platform 2022, and the palletized materials can move with the palletizing cart 200 in the first direction X.

[0041] The palletizing system can be configured to adjust the circumferential position of the first platform 102 and the linear position of the first platform 102 in the first direction X. This means it allows for adjustments to both the circumferential and linear positions of the pallet. For example, adjustments to the circumferential and linear positions can be used to align the edge angle of the pallet with the angle of the sheet divider, allowing the pallet to be matched with the maximum number of sheet dividers. The palletizing system uses automated drive components to adjust the specific position of the pallet, reducing manual intervention and improving production efficiency compared to existing technologies. Because manual intervention is required, the risk of damage to the edges of the pallet is reduced, thereby improving product quality.

[0042] In some embodiments, before the palletizing vehicle 200 enters the second platform 2022, the pallet can be loaded onto the first platform 102, and the pallet can rotate synchronously with the first platform 102. The rotation angle range of the first platform 102 can be ±90°.

[0043] As an example, the rotation angle of the first platform 102 can be controlled in real time via an encoder. The rotation angle configuration parameters of the first platform 102 can be configured differently according to different stacks of material. The angle configuration parameters corresponding to different stacks of material can be pre-input, and the corresponding parameters can be automatically retrieved before mold changing.

[0044] In some embodiments, the first mechanism 100 further includes a third drive component 103, which is drively connected to the first platform 102 and the first drive component 101. The third drive component 103 is used to drive the first platform 102 to move along the rotation axis Y and to drive the first platform 102 to move synchronously along the first direction X under the drive of the first drive component 101.

[0045] The first platform 102 can move along the rotation axis Y under the drive of the third drive component 103. When the first direction X is horizontal, the movement along the first direction X is a linear translational movement. That is, the first platform 102 can move in a direction perpendicular to the first direction X and can be raised and lowered relative to the first mechanism 100.

[0046] The palletizing cart 200 is parked on the first platform 102, meaning the palletizing cart 200 can be raised and lowered along with the first platform 102. The second platform 2022 is located on the palletizing cart 200, meaning the second platform 2022 can also be raised and lowered along with the palletizing cart 200 and the first platform 102, and the second platform 2022 can rotate relative to the palletizing cart 200.

[0047] The third drive component 103 can be linearly translated along the first direction X under the drive of the second drive component 2021. The first platform 102 is located on the third drive component 103, so the first platform 102, the palletizing vehicle 200, and the second platform 2022 can all move linearly along the first direction X with the third drive component 103.

[0048] For the stacked material on the second platform 2022, the stacked material can be translated linearly along the first direction X, can be raised and lowered in a direction perpendicular to the first direction X, and can rotate relative to the palletizing vehicle 200 to change its circumferential position. Through the configuration of the first drive component 101, the second drive component 2021 and the third drive component 103, the position adjustment of the stacked material can be realized in all aspects, making it more fully automatic and high-precision, and greatly improving production efficiency.

[0049] In some embodiments, the first drive assembly 101 includes a first drive motor 1011, a drive screw 1012, and a drive seat 1013. The drive seat 1013 is driven by the drive screw 1012, and the drive screw 1012 is driven by the first drive motor 1011 and drives the drive seat 1013 to move along the first direction X under the drive of the first drive motor 1011.

[0050] In some embodiments, optionally, the third drive component 103 is disposed on the drive housing 1013.

[0051] For example, the first drive unit 1011 can be a servo motor. The drive screw 1012 and the drive shaft of the first drive unit 1011 are coaxial and connected for transmission. The drive base 1013 is provided with a through hole, and the inner wall of the through hole is threaded. The drive screw 1012 and the through hole are threaded together. Under the drive of the first drive unit 1011, the drive base 1013 is driven to move along the length direction of the drive screw 1012, which is the first direction X. The first platform 102 is parallel to the drive base 1013 and is spaced above the drive base 1013. The third drive assembly 103 is provided on the drive base 1013, and the first platform 102 is provided on the third drive assembly 103.

[0052] The drive mechanism and drive screw 1012 are used in combination with threaded engagement to achieve the drive. While achieving translational drive in the first direction X, the structure of the first drive assembly 101 can be simplified. The rotational motion of the drive shaft of the first drive mechanism 1011 is converted into linear translational motion in the first direction X using the fewest possible components. This simplifies the structure of the palletizing system and improves the stability of translational motion in the first direction X by utilizing the guide of the drive screw 1012.

[0053] In some embodiments, the first drive assembly 101 further includes a support base 1014, which is provided with a linear guide rail 1014a extending along a first direction X. A drive base 1013 is slidably disposed on the linear guide rail 1014a. The drive base 1013 is capable of moving along the linear guide rail 1014a under the drive of the first drive motor 1011.

[0054] In some embodiments, the support body 1014 includes two parallel linear guide rails 1014a, the drive body 1013 is slidably disposed between the two linear guide rails 1014a, and the drive screw 1012 is disposed between the two linear guide rails 1014a and parallel to the linear guide rails 1014a. The drive screw 1012 drives the drive body 1013 to translate along the linear guide rails 1014a. The linear guide rails 1014a provide stable support for the drive body 1013, ensuring that the drive body 1013 has a stable translation process, thereby providing smooth movement along the first direction X for the third drive assembly 103, the first platform 102, and the palletizing cart 200 on the first platform 102.

[0055] The translation range of the drive body 1013 is ±500mm, and its translation range can be controlled in real time by an encoder. The translation range of the drive body 1013 can be configured differently according to different stacking materials. Translation parameters corresponding to different stacking materials can be pre-input, and the corresponding parameters can be automatically retrieved before mold changing.

[0056] In some embodiments, the second drive assembly 2021 includes a second drive motor 2021a and a meshing first gear 2021b and a second gear 2021c. The second gear 2021c is coaxially and driveably connected to the second platform 2022, and the first gear 2021b is coaxially and driveably connected to the second drive motor 2021a and can drive the first platform 102 to rotate under the drive of the second drive motor 2021a.

[0057] Gear meshing provides highly stable force transmission, and utilizing gear meshing to transmit rotational power can improve the rotational stability of the second platform 2022. After the stacking and loading are completed, the palletizing cart 200 enters the first platform 102 and stops on it. The second drive motor 2021a can be a servo motor. The second drive motor 2021a drives the second platform 2022 to rotate through the first gear 2021b and the second gear 2021c. The first platform 102 drives the second platform 2022 to translate along the first direction X or to rise and fall in a direction perpendicular to the first direction X. The second drive motor 2021a drives the second platform 2022 to rotate relative to the first platform 102.

[0058] In some embodiments, the second platform 2022 is spaced apart from its projection onto the palletizing cart 200 along the rotation axis Y, and the second drive assembly 2021 is located within the space. Specifically, the second gear 2021c may be coaxially located directly below the second platform 2022, the first gear 2021b may be located to the side of and mesh with the second gear 2021c, and the second drive motor 2021a may be located below or above the first gear 2021b and the second gear 2021c.

[0059] The second drive assembly 2021 is located in the gap between the projection of the second platform 2022 and the second platform 2022, which can avoid the space around the second platform 2022. The surrounding space can provide space for the configuration of the sheet divider, so as to effectively utilize the internal space of the palletizing vehicle 200.

[0060] In some embodiments, the second drive motor 2021a is located within the projection of the first gear 2021b and the second gear 2021c along the rotation axis Y on the palletizing vehicle 200, in order to improve the compactness of the second drive assembly 2021 and save other areas in the projection of the second platform 2022 along the rotation axis Y.

[0061] In some embodiments, the diameter of the first gear 2021b is smaller than that of the second gear 2021c. The difference in diameter between the first gear 2021b and the second gear 2021c can reduce the rotational speed of the second platform 2022, so that the rotational speed of the second platform 2022 and the stacked materials on it can be adapted to the preset speed without the need for an additional speed reduction device. This simplifies the structure of the second drive assembly 2021 and reduces the cost.

[0062] In some embodiments, the third drive assembly 103 includes a first hinge 1031 and a second hinge 1032 hinged together, with the first platform 102 and the drive seat 1013 arranged parallel and spaced apart. One end of the first hinge 1031 and one end of the second hinge 1032 are respectively hinged to the first platform 102, and the other ends of the second hinge 1032 and the drive seat 1013 are respectively hinged to each other. The angle between the first hinge 1031 and the second hinge 1032 is variable.

[0063] When the angle between the first hinge 1031 and the second hinge 1032 decreases, the ends of the first hinge 1031 and the second hinge 1032 on the same side move closer together, and the height of the first platform 102 increases. When the angle between the first hinge 1031 and the second hinge 1032 increases, the ends of the first hinge 1031 and the second hinge 1032 on the same side move further apart, and the height of the first platform 102 decreases, thus completing the lifting and lowering process. The first hinge 1031 and the second hinge 1032 are simultaneously slidably connected to the first platform 102 and the drive seat 1013.

[0064] In some embodiments, the third drive assembly 103 further includes a first telescopic member 1033 and a second telescopic member 1034. The fixing portion 103a of the first telescopic member 1033 is connected to the second hinge member 1032, and the telescopic portion 103b of the first telescopic member 1033 is connected to the first hinge member 1031. The fixing portion 103a of the second telescopic member 1034 is connected to the first hinge member 1031, and the telescopic portion 103b of the second telescopic member 1034 is connected to the second hinge member 1032.

[0065] The telescopic part 103b is movably inserted into the fixed part 103a and can extend or retract relative to the fixed part 103a. The movement of the telescopic part 103b relative to the fixed part 103a drives the first hinge member 1031 and the second hinge member 1032, causing the angle between the first hinge member 1031 and the second hinge member 1032 to change.

[0066] In practical applications, the palletizing vehicle 200 is generally parked on the ground. The second drive component 2021 mentioned above is located below the ground. When the third drive component 103 is at its lowest height, the upper surface of the first platform 102 is flush with the ground. The palletizing vehicle 200 can move from the ground to the first platform 102 and park on the upper surface of the first platform 102. It can perform translational or lifting movements as needed.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
