Description

Technical Field

[0001] This invention relates to the field of finished product transfer technology, specifically an automatic stacking and discharging device and a shell machine having the device. Background Technology

[0002] In existing technologies, after the shell-making machine completes production, the collection and stacking of finished products is a crucial subsequent process. Currently, the industry commonly uses suction cup robotic arms as the actuators, which use negative pressure to grip individual finished products and transfer them to a designated location for stacking. This method can achieve stable and efficient transfer for finished products with a certain thickness and rigidity. However, when dealing with thinner finished products, the reliability and stability of traditional suction cup gripping and dispensing methods face significant challenges.

[0003] The core problem lies in the fact that the thinner finished product itself has low structural strength. When it is lifted and moved solely by the negative pressure adsorption in the central area, it is extremely prone to overall or local deformation and bending due to its own weight and the inertia generated by the start and stop of the robotic arm. This deformation can cause gaps to form between the surface of the finished product and one or more suction cups, destroying the seal and thus causing local pressure relief.

[0004] To address this, existing technologies have developed a gripping method that utilizes a suction cup in conjunction with a support plate. The suction cup is used to grip the middle of the finished product, while the support plate is used to support the sides of the finished product. However, during use, the support plate requires two sets of cylinders to sequentially perform lateral and lifting movements, and the lateral and lifting movements have strict timing requirements. When the timing control fails, the support plate often fails to move into position or directly interferes with the finished product, affecting the stable transfer of the finished product. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic stacking and discharging device and a shell machine having the device, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic stacking and unloading device includes: A support table, wherein a movable frame and a support component are provided on the support table; A drive assembly is disposed on the support table and connected to the movable frame and the support member. When the movable frame is at the end of its stroke, the drive assembly can lift the support member upward. A truss connects to the support table. The truss is provided with a connecting plate that can move along a direction perpendicular to the length of the support table. The connecting plate is provided with a positive and negative pressure gripping structure that can adsorb the finished product lifted by the support member. Multiple clamping components are disposed on the side of the connecting plate. Each clamping component includes a sliding component, a first abutment, and a second abutment. The sliding component can drive the first abutment to perform lateral and vertical movements. When the first abutment performs vertical movements, the first abutment and the second abutment can move closer to each other.

[0007] The automatic stacking and unloading device as described above: the sliding component includes: A sliding connector is slidably installed in a groove formed on the connecting plate. A lifting member is slidably installed in the sliding connector. The first abutting member is fixedly connected to the lifting member, and the second abutting member is slidably connected to the lifting member. The fourth electric telescopic rod has one end rotatably connected to the traction plate set on the connecting plate, and the other end rotatably connected to the lifting component; A guide plate is fixedly installed on the connecting plate. The guide plate is provided with a guide groove, which cooperates with the lifting component to enable the lifting component to perform lateral and lifting actions when the fourth electric telescopic rod is activated.

[0008] As described above, the automatic stacking and unloading device has the following features: a linear drive module is fixedly installed on the truss, a third electric telescopic rod is fixedly installed on the linear drive module, and the actuating end of the third electric telescopic rod is fixedly connected to the connecting plate.

[0009] The automatic stacking and unloading device as described above: the lifting component includes a lifting shaft that slides through the sliding connector, and the lifting shaft connects the first abutment and the second abutment; The lifting component also includes a second convex shaft rotatably mounted on the lifting shaft, the second convex shaft being able to roll in the guide groove.

[0010] The automatic stacking and unloading device described above: the guide groove includes a second horizontal groove and a vertical groove disposed on the guide plate, the second horizontal groove and the vertical groove are connected and form an "L" shape.

[0011] The automatic stacking and unloading device described above: the sliding assembly further includes a guide groove formed on the sliding connector and a sliding plate slidably installed in the guide groove. Two sets of hinge rods are rotatably installed on the sliding plate, and the two sets of hinge rods are rotatably connected to the first abutment and the second abutment respectively.

[0012] As described above, the automatic stacking and unloading device includes two sets of guide rods fixedly installed at the bottom of the support table and a follower frame slidably installed on the guide rods. The follower frame is connected to a first electric telescopic rod set on the support table. The drive assembly also includes a lifting structure connecting the follower frame and the movable frame. The lifting structure can separate from the upper surface of the support table during the reverse movement of the follower frame to reset.

[0013] As described above, the automatic stacking and unloading device includes a lifting structure that is slidably mounted on the follower frame. The connecting frame passes through a horizontal slot on the support table and is connected to the movable frame. A second electric telescopic rod is fixedly installed on the connecting frame, and the actuating end of the second electric telescopic rod is connected to the follower frame.

[0014] As described above, the automatic stacking and unloading device includes a drive assembly that further comprises a follower plate connected to the follower frame and a first convex shaft rotatably connected to the support member. The follower plate is provided with a first horizontal groove and an inclined groove. The first convex shaft can roll in the first horizontal groove and the inclined groove. When the first convex shaft rolls in the inclined groove, the support member can perform a lifting action.

[0015] A shell-making machine includes the aforementioned automatic stacking and discharging device.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By using the clamping components, when the fourth electric telescopic rod is activated, the lifting shaft can sequentially perform lateral movement and lifting motion. During lateral movement, the first and second abutting parts can overlap with the side of the finished product, providing a positional basis for subsequent clamping actions. During lifting motion, the first and second abutting parts can move closer to each other to achieve a clamping effect on the finished product. The lateral movement and clamping are performed step by step, improving the timing of the actions of the first and second abutting parts. That is, the action of lateral movement followed by clamping is strictly executed, and the corresponding actions can be completed with a single drive source. Moreover, this clamping can generate a certain lateral pulling force on the finished product, thereby preventing the finished product from bending and collapsing in the middle due to gravity, and ensuring effective adhesion between the middle of the finished product and the suction cup. By designing the drive components, moving frame, and support components, it is ensured that the finished product will not shift position after being transported to its designated location when the moving frame resets. Furthermore, the moving frame can cycle during operation, ensuring a consistent conveying rhythm for the finished product. When the moving frame resets to its initial position, it makes room for the clamping components, ensuring that the clamping components can stably act on the side of the finished product. At the same time, the support components ensure that the positive and negative pressure gripping structure and the clamping components can better act on the finished product, guaranteeing that the finished product can be stably gripped.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figures 1-11 As an embodiment of the present invention, the automatic stacking and unloading device includes: a support table 1, a drive assembly, a truss 11, and multiple sets of clamping assemblies.

[0031] The support table 1 is equipped with a movable frame 2 and a support component 9; The drive assembly is mounted on the support table 1 and connected to the movable frame 2 and the support member 9. When the movable frame 2 is at the end of its stroke, the drive assembly can lift the support member 9 upward. The drive assembly includes two sets of guide rods 5 fixedly installed at the bottom of the support table 1 and a follower frame 4 slidably installed on the guide rods 5. The follower frame 4 is connected to the first electric telescopic rod 3 set on the support table 1.

[0032] After the shell-making machine completes production, the finished product can be transported to the inside of the mobile frame 2 by the conveyor belt. At this time, the first electric telescopic rod 3 will be activated and push the mobile frame 2 to move along the length of the bearing table 1 so that the finished product in the mobile frame 2 can change position, so as to provide a precise position basis for subsequent gripping of the finished product.

[0033] An inclined surface is provided on the top of the inner side of the movable frame 2. This inclined surface can guide the finished product into the interior of the movable frame 2, and to a certain extent ensure that the finished product can stably follow the movement of the movable frame 2, thereby realizing position switching.

[0034] Please see Figures 2-5 The drive assembly also includes a lifting structure connecting the follower frame 4 and the movable frame 2. The lifting structure can separate from the upper surface of the support table 1 during the process of the follower frame 4 moving in the opposite direction to reset. The lifting structure includes a connecting frame 6 slidably mounted on the follower frame 4. The connecting frame 6 passes through the horizontal slot 101 on the support table 1 and is connected to the movable frame 2. A second electric telescopic rod 7 is fixedly installed on the connecting frame 6, and the actuating end of the second electric telescopic rod 7 is connected to the follower frame 4.

[0035] In the initial state, the second electric telescopic rod 7 is in a state where the lower end face of the moving frame 2 is coplanar with the upper surface of the bearing table 1. At this time, the inner side of the moving frame 2 can be stably in contact with the side of the finished product. In this state, when the moving frame 2 is displaced, the finished product will also be stably displaced, ensuring the positional accuracy of the finished product.

[0036] When the first electric telescopic rod 3 drives the moving frame 2 to move in the opposite direction, the second electric telescopic rod 7 will act before the first electric telescopic rod 3, driving the moving frame 2 to move upward through the connecting frame 6, so that a certain gap is created between the moving frame 2 and the supporting table 1. This gap is greater than the thickness of the finished product, so that when the moving frame 2 moves in the opposite direction, it will not cause the finished product to move in the opposite direction as well. In this way, on the one hand, it can ensure that after the finished product is transported to the position, the reset of the moving frame 2 will not cause the finished product to shift in position. On the other hand, the moving frame 2 can move in a cycle during operation to ensure the rhythm of transferring the finished product. And when the moving frame 2 resets to the initial position, it can make room for the clamping component to ensure that the clamping component can stably act on the side of the finished product.

[0037] It should be noted that the space area inside the aforementioned mobile frame 2 is slightly larger than the space area of ​​the finished product, so that the finished product can be easily transported into the mobile frame 2. At the same time, during the upward movement of the mobile frame 2, the friction between its inner side and the finished product will not cause the mobile frame 2 to drive the finished product upward.

[0038] Please see Figure 4 The drive assembly also includes a follower plate 8 connected to the follower frame 4 and a first convex shaft 10 rotatably connected to the support member 9; The follower plate 8 is provided with a first horizontal groove 801 and an inclined groove 802. The first convex shaft 10 can roll in the first horizontal groove 801 and the inclined groove 802. When the first convex shaft 10 rolls in the inclined groove 802, the support member 9 can perform a lifting action.

[0039] In this embodiment, when the moving frame 2 is at the start of the stroke, the follower frame 4 is also at the start of the stroke. At this time, the first convex shaft 10 is at the end of the inclined groove 802 away from the first horizontal groove 801. At this time, the support member 9 is in the state of being lifted upward. In this state, the positive and negative pressure gripping structure and clamping components can better act on the finished product to ensure that the finished product can be gripped stably.

[0040] As the moving frame 2 moves the finished product downwards toward the clamping assembly, the follower plate 8 will follow suit. At this time, the first convex shaft 10 will move sequentially along the inclined groove 802 and the first horizontal groove 801, causing the height of the support member 9 to decrease until the upper surface of the support member 9 coincides with the upper surface of the bearing table 1. At this time, the first convex shaft 10 is in the first horizontal groove 801. In this way, when the moving frame 2 pushes the finished product to the position of the support member 9, it can move the finished product to the upper part of the support member 9, preventing the support member 9 from being in a state that protrudes from the upper surface of the bearing table 1, which would cause interference between it and the moving frame 2 and the finished product.

[0041] Please see Figures 1-2The truss 11 is connected to the support table 1. The truss 11 is provided with a connecting plate 14 that can move along the length direction perpendicular to the support table 1. Specifically, a linear drive module 12 is fixedly installed on the truss 11. A third electric telescopic rod 13 is fixedly installed on the linear drive module 12. The actuating end of the third electric telescopic rod 13 is fixedly connected to the connecting plate 14.

[0042] In this embodiment, the truss 11 extends to the side of the support table 1, and a stacking platform (not shown in the figure) is provided on the side of the support table 1. The stacking platform can actively adjust the reference height according to the number of finished products stacked, so that the final height of the clamping component is constant when placing the finished products.

[0043] Specifically, the initial state of the connecting plate 14 can be adjusted by the third electric telescopic rod 13, so that the height of the positive and negative pressure gripping structure and the clamping component can be adjusted. After the two complete the gripping of the finished product, the finished product can be lifted to a certain height and then the linear drive module 12 is used to move the finished product laterally, avoiding direct lateral movement that causes friction between the finished product and the upper surface of the support table 1, resulting in scratches on the finished product.

[0044] Please see Figure 8 The connecting plate 14 is provided with a positive and negative pressure gripping structure, which can adsorb the finished product lifted by the support member 9. The positive and negative pressure gripping structure includes multiple sets of suction cups 17 fixedly installed on the connecting plate 14. The multiple sets of suction cups 17 are connected to the negative pressure generating device 15 and the air pumping device 16 provided on the connecting plate 14.

[0045] In this embodiment, when the third electric telescopic rod 13 drives the connecting plate 14 toward the finished product, the finished product is in a state of being lifted by the support member 9. When the connecting plate 14 descends to a predetermined height, the air pumping device 16 will activate first, spraying compressed gas through the suction cup 17. The compressed gas acts on the surface of the finished product to remove dust and other impurities from the surface of the finished product. Then, when the suction cup 17 adheres to the surface of the finished product, one side of the finished product is supported by the support member 9, and the other side is pressed against the suction cup 17. At the same time, the negative pressure generating device 15 activates, causing a negative pressure to be generated inside the suction cup 17, thereby using the suction cup 17 to adsorb the middle part of the finished product.

[0046] In this application, the clamping component acts on the side of the finished product, and the suction cup 17 adsorbs and grips the middle of the finished product. This can prevent the finished product from bending and collapsing in the middle under the action of gravity, ensure the straightness of the finished product during the transfer process, and to a certain extent prevent the finished product from bending and collapsing in the middle, causing its end to slip off relative to the clamping component, thereby improving the stability of the finished product during movement.

[0047] It is worth noting that after the finished product is produced, one side is smooth and the other side is rough. In this embodiment, the smooth side of the finished product needs to face upwards to ensure the stability of the suction cup 17 when it is adsorbed and gripped.

[0048] Please see Figures 6-10 Multiple sets of clamping components are disposed on the side of the connecting plate 14. Each clamping component includes a sliding component, a first abutting member 23 and a second abutting member 24. The sliding component can drive the first abutting member 23 to perform lateral and vertical movements. When the first abutting member 23 performs vertical movements, the first abutting member 23 and the second abutting member 24 can move closer to each other. The sliding assembly includes: a sliding connector 20, a fourth electric telescopic rod 19, and a guide plate 26.

[0049] The sliding connector 20 is slidably installed in the groove 1401 opened on the connecting plate 14. A lifting member is slidably installed in the sliding connector 20. The lifting member includes a lifting shaft 22 that slides through the sliding connector 20. The lifting shaft 22 connects the first abutment 23 and the second abutment 24. The lifting component also includes a second convex shaft 25 rotatably mounted on the lifting shaft 22. One end of the fourth electric telescopic rod 19 is rotatably connected to the traction plate 18 set on the connecting plate 14, and the other end is rotatably connected to the lifting component. The guide plate 26 is fixedly installed on the connecting plate 14. The guide plate 26 is provided with a guide groove. The second convex shaft 25 can roll in the guide groove so that when the fourth electric telescopic rod 19 is activated, the lifting shaft 22 can perform lateral and lifting actions. The guide groove includes a second horizontal groove 2601 and a vertical groove 2602 provided on the guide plate 26. The second horizontal groove 2601 and the vertical groove 2602 are connected and form an "L" shape.

[0050] In this embodiment, initially, the second convex shaft 25 is located at the end of the second horizontal groove 2601 away from the vertical groove 2602. At this time, the lifting shaft 22 is at the lower end of its stroke, and the first abutting member 23 and the second abutting member 24 are misaligned with the side end of the finished product. After the suction cup 17 completes the adsorption of the finished product, the fourth electric telescopic rod 19 will be activated. At this time, the second convex shaft 25 will move sequentially along the second horizontal groove 2601 and the vertical groove 2602. When the second convex shaft 25 moves along the second horizontal groove 2601, it can drive the lifting shaft 22 and the sliding connector 20 along the slide groove 14. The length direction of the 01 moves the first abutment 23 toward the finished product and eventually it is below the side end of the finished product. When the second convex shaft 25 moves along the vertical groove 2602, the first abutment 23 will move upward under the pull of the lifting shaft 22 until the first abutment 23 abuts against the lower end of the finished product. At this time, the first abutment 23 can support the side end of the finished product, ensuring the straightness of the finished product and preventing the finished product from bending due to gravity, inertia and other reasons during the transfer process, which would cause a gap at the connection between the finished product and the suction cup 17 and cause negative pressure failure.

[0051] Please see Figure 7 , Figure 9 The first abutting member 23 is fixedly connected to the lifting shaft 22, and the second abutting member 24 is slidably connected to the lifting shaft 22; The sliding assembly further includes a guide groove 2001 formed on the sliding connector 20 and a sliding plate 21 slidably installed in the guide groove 2001. Two sets of hinge rods 27 are rotatably installed on the sliding plate 21, and the two sets of hinge rods 27 are rotatably connected to the first abutment 23 and the second abutment 24 respectively.

[0052] In this embodiment, in the initial state, the distance between the first abutment 23 and the upper surface of the finished product is equal to the distance between the second abutment 24 and the lower surface of the finished product. When the lifting shaft 22 drives the first abutment 23 to move upward, the hinge rod 27 connected to the first abutment 23 will push the sliding plate 21 to move away from the lifting shaft 22 along the length direction of the guide groove 2001. At the same time, the hinge rod 27 connected to the second abutment 24 will pull the second abutment 24 to move downward along the length direction of the lifting shaft 22. That is, during this process, the first abutment 23 and the second abutment 24 are in a state of close proximity to each other. Thus, when the two are in contact with the surface of the finished product, a clamping effect is generated on the finished product. Under the dual action of being clamped at the side end of the finished product and being adsorbed and grasped in the middle, the stability of the finished product during the transfer process is ensured, the finished product is prevented from falling, and the transfer success rate is improved.

[0053] Based on the above configuration, when the fourth electric telescopic rod 19 is activated, the lifting shaft 22 can sequentially perform lateral movement and lifting movements. During lateral movement, the first abutment 23 and the second abutment 24 can overlap with the side of the finished product, providing a positional basis for subsequent clamping movements. During lifting movements, the first abutment 23 and the second abutment 24 can move closer to each other to achieve a clamping effect on the finished product. The lateral movement and clamping are performed step by step in sequence, improving the timing of the actions of the first abutment 23 and the second abutment 24, and enabling the corresponding actions to be completed with a single drive source. Moreover, this clamping can generate a certain lateral pulling force on the finished product, thereby preventing the finished product from bending and collapsing in the middle due to gravity, and ensuring effective contact between the middle of the finished product and the suction cup 17.

[0054] Furthermore, by stably gripping the middle and side ends of the finished product, the middle and side ends of the finished product will be subjected to effective gripping force during the gripping process, ensuring the uniformity of the force on the finished product. This avoids the bending and deformation of thinner finished products due to gravity, inertia and other reasons during the transfer process, which could lead to adsorption failure or clamping detachment, thus improving the stability when conveying thinner finished products.

[0055] Furthermore, since the first abutment member 23 and the second abutment member 24 clamp the side end of the finished product, the finished product can be prevented from bending and deforming due to gravity in the area between the suction cup 17 and the side end, thereby further improving the gripping stability.

[0056] As an embodiment of the present invention, a shell-making machine is also proposed, including the aforementioned automatic stacking and discharging device.

[0057] 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 implemented in other specific forms without departing from its spirit or essential characteristics.
