Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a stacking and destacking mechanism suitable for automated production lines. Background Technology

[0002] Automated production lines, such as automotive CMD production lines, require depalletizing mechanisms. Current technologies often employ manual depalletizing, where workers place products into boxes, then onto corresponding machines, and then sequentially remove and place them onto their designated pallets. This manual operation increases labor costs, results in low production efficiency, and is ill-suited for efficient, integrated, and flexible production processes.

[0003] For example, CN119349292A discloses a stacking and destacking mechanism, which uses a transmission mechanism in conjunction with a stacking and destacking mechanism and a positioning mechanism to achieve automated integrated operation that replaces manual labor, greatly improving operational efficiency.

[0004] Regarding the aforementioned disclosed technology, actual research has revealed the following drawbacks:

[0005] First, for the stacking part of the stacking mechanism, the side clamping cylinder is needed to achieve limit control during the stacking of empty pallets. The design of the side clamping cylinder requires precise control of its stroke to match the action of the stepper motor of the stacking part, which increases the complexity of the control process design.

[0006] Secondly, the process of controlling the motion trajectory of the positioning mechanism carried by the transmission belt is difficult to control with high precision. Therefore, the disclosed technology requires the use of a side clamping cylinder in conjunction with a fixed frame to position the loading pallet as it is transported from the beginning to the end of the transmission mechanism.

[0007] Therefore, given the lack of structural simplification in the automated stacking and destacking mechanisms used in existing technologies, further optimization of their structure is necessary. Utility Model Content

[0008] The purpose of this invention is to provide a stacking and destacking mechanism suitable for automated production lines, thereby solving the technical problem of simplifying its overall structure.

[0009] The stacking and destacking mechanism of this utility model, applicable to automated production lines, is implemented as follows:

[0010] A destacking and stacking mechanism suitable for automated production lines includes: a destacking component, a stacking component disposed on one side of the destacking component, a unloading station located on the side of the destacking component facing away from the stacking component, and a conveying component disposed between the stacking component, the destacking component, and the unloading station for conveying a loading tray; wherein

[0011] The stacking assembly, destacking assembly, and unloading station are arranged in a straight line, and the conveying assembly includes a platform for carrying the loading tray, and a linear motion module connected to the platform for driving the platform to move linearly; and

[0012] The destacking assembly includes multiple tray stops for forming a tray area for receiving a loading tray, a first lifting drive located below the tray area for driving the loading tray to move up and down, and a pair of side clamping cylinders located on one of the pair of side end faces of the tray area to limit the loading tray.

[0013] The stacking assembly includes a plurality of tray stops for forming a tray area for receiving a tray, a second lifting drive located below the tray area for driving the tray to move up and down, and a pair of side stop blocks located on one of the pair of side end faces of the tray area to limit the tray.

[0014] In an optional embodiment of this utility model, the stacking and destacking mechanism for automated production lines further includes a pair of oppositely distributed support frames that are simultaneously connected to the stacking assembly, the destacking assembly, and the unloading station.

[0015] The pair of support frames extend along the direction of motion of the linear motion module, and the transmission component is disposed in the interval formed by the pair of support frames.

[0016] In an optional embodiment of this utility model, the linear motion module is a linear lead screw module.

[0017] In an optional embodiment of this invention, the first lifting drive is a cylinder; and

[0018] The first lifting drive supports the loading tray through multiple first support columns; and a first clearance interval is formed between the multiple first support columns, which is suitable for the platform to pass through when it makes a linear motion under the action of the linear motion module.

[0019] In an optional embodiment of this invention, the second lifting actuator is a cylinder; and

[0020] The second lifting drive supports the loading tray through multiple second support columns; and a second clearance interval is formed between the multiple second support columns, which is suitable for the platform to pass through when it makes a linear motion under the action of the linear motion module.

[0021] In an optional embodiment of this invention, each of the side clamp cylinder assemblies includes a lateral support block adapted to support the loading tray from the side end face of the loading tray, and a side drive cylinder connected to the lateral support block for driving the lateral support block to move relatively closer to and away from the loading tray.

[0022] In an optional embodiment of this invention, each of the side-locking blocks includes a fixed seat fixed to the support frame and a movable block rotatably connected to the fixed seat.

[0023] In an optional embodiment of this invention, the fixed base has a receiving cavity for rotatably engaging with the movable block; and

[0024] One end of the movable block is adapted to extend out of the side of the receiving cavity facing the tray area.

[0025] In an optional embodiment of this invention, the side end of the movable block facing the tray area is a conical head, and the end face of the conical head facing the second lifting drive is an inclined surface.

[0026] In an optional embodiment of this invention, the end face of the movable block facing away from the second lifting driver is a smooth flat end face; and

[0027] The ends of the multiple movable blocks facing away from the second lifting driver are located on the same end face.

[0028] By adopting the above technical solution, this utility model has the following beneficial effects: The stacking / destacking mechanism of this utility model, applicable to automated production lines, uses a linear motion module to drive the platform movement, which reduces the difficulty of precisely controlling the platform's movement trajectory. This allows the platform to accurately move between the stacking assembly, destacking assembly, and unloading station to a suitable position to achieve the transfer of the loading tray. Furthermore, for the stacking assembly, the side anti-locking block is designed to adapt to the lifting and lowering movement of the loading tray, thus eliminating the need for additional precise control in its use. Therefore, the stacking / destacking mechanism of this utility model, applicable to automated production lines, simplifies its overall structure while meeting the requirements for automated stacking and destacking.

[0034] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0035] Please see Figures 1 to 4 As shown, this embodiment provides a destacking and stacking mechanism suitable for automated production lines, including: a destacking component 1, a stacking component 2 disposed on one side of the destacking component 1, a material unloading station 3 located on the side of the destacking component 1 facing away from the stacking component 2, and a conveying component disposed between the stacking component 2, the destacking component 1 and the material unloading station 3 for conveying the loading tray 9.

[0036] It should be noted that the stacking assembly 2, destacking assembly 1, and unloading station 3 are arranged in a straight line, and the conveying assembly includes a platform 41 for carrying the loading tray 9, and a linear motion module 42 connected to the platform 41 for driving the platform 41 to make linear movements. The linear motion module 42 here can be a linear screw module. The linear screw module used here can be any mature means in the prior art. The specific structure and implementation principle are not limited in this embodiment. By using the linear screw module to drive the platform 41, the difficulty of accurately controlling the movement trajectory of the platform 41 can be reduced, so that the platform 41 can accurately flow between the stacking assembly 2, destacking assembly 1, and unloading station 3 to a suitable position to realize the conveying of the loading tray 9.

[0037] It is also necessary to explain that the stacking and destacking mechanism applicable to automated production lines in this embodiment also includes a pair of oppositely distributed support frames 8 that are simultaneously connected to the stacking component 2, the destacking component 1 and the unloading station 3; the pair of support frames 8 extend along the movement direction of the linear motion module 42, and the conveying component is disposed in the interval formed by the pair of support frames 8.

[0038] Next, we will describe in detail the destacking assembly 1, which includes multiple tray stops 51 for forming a tray area for receiving the loading tray 9, a first lifting drive 52 located below the tray area for driving the loading tray 9 to move up and down, and a pair of side clamping cylinders located on one pair of side end faces of the tray area to limit the loading tray 9. For example, for a generally used square loading tray 9, four tray stops 51 can be provided, and these four tray stops 51 can be L-shaped structures located at the four corners of the loading tray 9.

[0039] Based on the above, furthermore, the first lifting drive 52 uses a cylinder; and the first lifting drive 52 supports the loading tray 9 through multiple first support columns 53; and a first clearance interval is formed between the multiple first support columns 53, suitable for the platform 41 to pass through when it makes a linear motion under the action of the linear motion module 42. Optionally, four first support columns 53 are used, with each pair of first support columns 53 forming a group, and the two groups of first support columns 53 are respectively set on both sides of the linear motion module 42.

[0040] In addition, it should be noted that each side clamp cylinder assembly includes a lateral support block 54 adapted to support the loading tray 9 from the side end face of the loading tray 9, and a side drive cylinder 55 connected to the lateral support block 54 for driving the lateral support block 54 to move relatively closer to and away from the loading tray 9.

[0041] Secondly, the stacking assembly 2 includes multiple tray stops 61 for forming a tray area for receiving the loading tray 9, a second lifting drive 62 located below the tray area for driving the loading tray 9 to move up and down, and a pair of side stop blocks 7 located on one of the pair of side end faces of the tray area to limit the loading tray 9. The specific design of the stored tray stops 61 can be the same as that of the tray stops 51 in the destacking assembly 1, so it will not be described in detail here.

[0042] Based on the above, furthermore, the second lifting drive 62 employs a cylinder; and the second lifting drive 62 supports the loading tray 9 via multiple second support columns 63; and a second clearance interval is formed between the multiple second support columns 63, suitable for the platform 41 to pass through when it makes a linear motion under the action of the linear motion module 42. Optionally, four second support columns 63 are used, with each pair of second support columns 63 forming a group, and the two groups of second support columns 63 are respectively arranged on both sides of the linear motion module 42.

[0043] Next, we will describe in detail that each side anti-reverse block 7 includes a fixed seat 71 fixed to the support frame and a movable block 72 rotatably connected to the fixed seat 71. More specifically, the fixed seat 71 has a receiving cavity for rotatably engaging with the movable block 72; and one end of the movable block 72 is adapted to extend out of the receiving cavity to the side facing the tray area. The movable block 72 may be rotatably engaged with the fixed seat 71 by, for example, but not limited to, a pin. In addition to the pin, an elastic torsion spring may also be provided between the movable block 72 and the fixed seat 71, so that when the movable block 72 is not subjected to external force, after the movable block 72 forms an angle with the fixed seat 71, the conical head 73 of the movable block 72 still partially protrudes from the fixed seat 71 and extends into the tray area. Furthermore, the side end of the movable block 72 facing the tray area is a conical head 73, and the end face of the conical head 73 facing the second lifting drive 62 is an inclined surface K. The end face of the movable block 72 facing away from the second lifting driver 62 is a smooth flat end face; and the end faces of multiple movable blocks 72 facing away from the second lifting driver 62 are located on the same end face.

[0044] Based on the above-described structure of the side anti-reverse block 7, for multiple longitudinally stacked loading trays 9, the stacked loading trays 9 are stacked from bottom to top. When it is not necessary to stack a new loading tray 9, the movable block 72 in the multiple side anti-reverse blocks 7 is used to support the bottom of the lowest loading tray 9 in the longitudinal stack. When a new loading tray 9 is to be stacked from below, as the new loading tray 9 rises continuously under the action of the second lifting drive 62, the new loading tray 9 will push against the inclined surface of the conical head 73 of the movable block 72, causing the movable block 72 to rotate relative to the fixed seat 71 due to the pushing force and no longer support the loading tray 9 that was originally in contact with it. At this time, since there are positioning parts 91 that are interlocked between the multiple longitudinally distributed loading trays 9, the new loading tray 9 will provide bottom support for the loading tray 9 that was originally supported by the movable block 72. Therefore, the rotation of the movable block 72 will not cause the loading trays 9 that were originally in the stacked state to collapse. As the new loading tray 9 rises, it simultaneously lifts the previously stacked loading trays 9 until the new loading tray 9 moves above the movable block 72. At this point, the movable block 72, under the action of the elastic torsion spring, forms an angle with the fixed base 71, causing the conical head 73 of the movable block 72 to partially protrude from the fixed base 71 and extend into the loading area. Next, the new loading tray 9 and the other loading trays 9 descend together. As the loading tray 9 contacts the conical head 73 of the movable block 72, the movable block 72 rotates relative to the fixed base 71, causing the last loading tray 9 in the current stacked state to press onto the movable block 72. Thus, the movable block 72 again provides bottom support for the stacked loading trays 9, and the second lifting drive 62 can then disengage from the loading tray 9. Therefore, for the stacking assembly 2 in this embodiment, the design of the side anti-reverse block 7 is adaptively changed according to the lifting movement of the loading tray 9, so that the use of the side anti-reverse block 7 does not require additional precise control. Therefore, its overall structure can be simplified while meeting stacking requirements.

[0045] In summary, the specific usage process of the stacking and destacking mechanism applicable to automated production lines in this embodiment is as follows:

[0046] The operator manually places the product-filled trays 9 into the corresponding tray area of ​​the destacking assembly 1. At this time, a pair of side-clamping cylinders support the bottom of the stacked trays 9. Then, the operator leaves, and the first lifting drive 52 rises so that the first support column 53 supports the bottom tray 9 in the stacked state. At this time, the pair of side-clamping cylinders move away from the trays 9, and the first lifting drive 52 drives all the trays 9 to move down. When the second to last tray 9 in the stacked state is aligned with the side-clamping cylinders, the pair of side-clamping cylinders move towards the tray 9, so that the pair of side-clamping cylinders support the bottom of the second to last tray 9 in the stacked state. At this point, the first lifting drive 52 can drive the bottommost loading tray 9, which is stacked, to continue moving downwards until it is placed on the platform 41. The linear motion module 42 then moves the loading tray 9 on the platform 41 to the unloading station 3, where a robotic arm or robot removes the material from the loading tray 9. After all the material in the loading tray 9 has been removed, the linear motion module 42 moves the empty loading tray 9 on the platform 41 to the stacking assembly 2 for stacking. The specific stacking process is described in the above embodiment and will not be repeated here. After the empty loading trays 9 are stacked, the linear motion module 42 moves the platform 41 back to the destacking assembly 1 for a new round of destacking and stacking operations. The overall process is highly automated, and the stroke and operation are precise and reliable, greatly improving operational efficiency.
