Description

Technical Field

[0001] This application belongs to the technical field of production line logistics equipment, specifically relating to a pallet limiting and stacking device for production line trolleys. Background Technology

[0002] Production line trolleys are widely used on production lines, mainly to move materials and parts from one place to another in the production process to ensure the continuous operation of the production line. They usually have high movement speed and positioning accuracy, and can quickly and accurately complete material handling tasks. In addition, production line trolleys are also equipped with special tooling fixtures to adapt to the handling needs of different workpieces.

[0003] The pallet limiting and stacking device for production line trolleys is a piece of equipment used on the production line. It is mainly used to limit and stack pallets during the trolley pushing process. This device is usually installed at a specific location on the production line and controls the movement and stacking of pallets by mechanical or electronic means to ensure that pallets are accurately stopped and stacked in the designated position.

[0004] In existing technologies, without cushioning devices when pallets are placed, materials may tip over or collide due to the impact of gravity, causing damage to the goods. The bumps when the trolley moves will be directly transmitted to the pallet, causing the center of gravity of the stack to shift, and even triggering a chain reaction of goods tipping over, increasing the risk of safety accidents. At the same time, it cannot adapt to pallets of different heights, and during transportation, materials may slip off the edge of the pallet due to shaking or sudden stops. When the trolley turns or accelerates, it is easy for the trolley to slide laterally due to inertia, causing the goods to tilt or even slip off the side of the trolley, resulting in unnecessary economic losses.

[0049] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0050] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0051] In some embodiments, please refer to Figures 1 to 12. Figure 4 This application provides a pallet limiting and stacking device for a production line trolley, comprising four rollers 1;

[0052] Buffer limiting component 6 is installed on top of the four rollers 1;

[0053] Four fasteners 601 are installed on the top of the four rollers 1;

[0054] Four hydraulic cylinders 602 are fixedly encapsulated on the top of four fixing parts 601;

[0055] Four hydraulic push rods 611 are mounted on top of four fixing members 601;

[0056] Four pressure plates 613 are installed on the top of four hydraulic push rods 611, and the bottom of each of the four pressure plates 613 is provided with anti-slip texture.

[0057] In this embodiment, the entire production line trolley is first moved to the required stacking area via four rollers 1. A person or a robotic arm places the pallet with the goods on the center of the pallet platform 604. The pallet triggers the weight sensor at the bottom of the pallet platform 604, and the system confirms that the goods are in place. At this time, the laser sensor starts scanning the height of the pallet. At this time, the four hydraulic cylinders 602 are started simultaneously, pushing the pallet platform 604 to rise along the slide column 605. At this time, the spring 606 is stretched. The four hydraulic push rods 611 on both sides calculate the distance that the pressure plate 613 will descend based on the laser sensor data, and drive the four hydraulic push rods 611 to make the four pressure plates 613 descend slowly. When the pressure plate 613 contacts the top of the goods on the pallet, the pressure sensor feeds back the clamping force. At this time, the system automatically fine-tunes to the optimal pressure, and the anti-slip texture fits tightly with the pallet surface to prevent horizontal displacement.

[0058] In some embodiments, four rollers 1;

[0059] Frame 2 is bolted to the top of the four rollers 1;

[0060] Workbench 3 is fixedly connected to the top of frame 2;

[0061] Handle 4 is fixedly connected to one side of the outer wall of the workbench 3;

[0062] Two protective sleeves 5 are fixedly adhered to one side of the outer wall of the frame 2.

[0063] In this embodiment, workers can move the entire production line trolley to the required stacking area by holding the handle 4 and using the four rollers 1. Since the frame 2 is bolted to the top of the four rollers 1 and the workbench 3 is fixedly connected to the top of the frame 2, the four rollers 1 not only perform the function of movement, but also provide sufficient support for the numerous components connected to them. At the same time, the frame 2 is a reinforced structure that can ensure that the goods will not vibrate significantly during movement and provides sufficient rigid support. Furthermore, the two protective sleeves 5 are fixedly adhered to one side of the outer wall of the frame 2. The two protective sleeves 5 can ensure that the palletized goods will not vibrate significantly due to collisions during the movement of the entire trolley, and can provide cushioning force for impacts. At the same time, they can also ensure that the workbench 3 of the trolley will not deform due to external collisions.

[0064] In some embodiments, four hydraulic cylinders 602;

[0065] Four connectors 603 are fixedly sleeved on the shaft ends of four hydraulic cylinders 602;

[0066] The support 604 is bolted to the top of the four connectors 603.

[0067] In this embodiment, after the palletized goods are fully placed on top of the platform 604, the linear motion of the piston of the hydraulic cylinder 602 is rigidly transmitted to the connector 603 at the bottom of the platform 604 through the piston rod, realizing the vertical lifting and lowering of the platform 604 along the slide column 605. The synchronous movement of the four hydraulic cylinders 602 can ensure the stability of the platform 604 during lifting and lowering, and prevent the goods from tilting.

[0068] In some embodiments,

[0069] Workbench 3;

[0070] Four 607 flanges are bolted to the top of workbench 3;

[0071] Four fasteners 601 are bolted to the bottom of the four fasteners 601 and to the top of the worktable 3;

[0072] Four sliding pillars 605 are fixedly connected to the top of four flanges 607, and the outer surfaces of the four sliding pillars 605 are movably connected to the support platform 604.

[0073] In this embodiment, four flanges 607 are first bolted to the top of the workbench 3, and the bottom of four fasteners 601 are bolted to the top of the workbench 3. At this time, the workbench 3 provides support for the connected components, which can ensure that no collapse will occur during movement or stacking. Meanwhile, the four sliding columns 605 can ensure that the support platform 604 will not vibrate significantly during the rising and falling process.

[0074] In some embodiments, four flanges 607;

[0075] Four springs 606 are elastically connected to the top of four flanges 607, and the top of the four springs 606 is connected to the bottom of the support 604.

[0076] In this embodiment, four springs 606 are elastically connected to the top of four flanges 607, and the top of the four springs 606 is connected to the bottom of the support platform 604. The rigid connection between the support platform 604 and the springs 606 forms an elastic support platform. The elastic deformation of the springs 606 absorbs the impact force during loading and unloading of goods, while preventing the hydraulic system from being subjected to instantaneous overload.

[0077] In some embodiments, the support platform 604;

[0078] Four elastic meshes 608 are fixedly connected to the top of the support 604, and the four elastic meshes 608 are interconnected and placed symmetrically.

[0079] In this embodiment, four elastic meshes 608 are fixedly connected to the top of the support platform 604. The elastic meshes 608 are made of a blend of spandex and nylon. When irregularly shaped goods are placed, the elastic meshes 608 will stretch in different directions due to the protruding parts of the goods.

[0080] In some embodiments, four elastic meshes 608;

[0081] Four connectors 609 are bolted to the top of two of the elastic meshes 608, and the bottom of the four connectors 609 is bolted to the top of the four sliding pillars 605.

[0082] In this embodiment, four connecting members 609 are first bolted to the top of two of the elastic meshes 608, and the bottom of the four connecting members 609 is bolted to the top of the four sliding pillars 605. The elastic meshes 608 and the sliding pillars 605 are connected by the connecting members 609, so that the mesh will not collapse due to deformation when bearing goods of different shapes.

[0083] In some embodiments, the support platform 604;

[0084] Four metal plates 610 are bolted to the bottom of the support 604, and the top of the four metal plates 610 is connected to the bottom of the four hydraulic push rods 611.

[0085] Four metal fixing plates 612 are fixedly sleeved on the shaft ends of four hydraulic push rods 611, and the top of the four metal fixing plates 612 is bolted to the bottom of the four pressure plates 613.

[0086] In this embodiment, four metal plates 610 are first bolted to the bottom of the support platform 604, and the top of the four metal plates 610 is connected to the bottom of the four hydraulic push rods 611. At this time, the support platform 604 bears the force from the hydraulic push rods 611 pressing down on the goods. The connection by the bolts ensures that the hydraulic push rods 611 will not collapse due to insecure fixing during the clamping process.

[0087] In some embodiments, the support platform 604;

[0088] Silicone anti-slip sleeve 614 is fixedly wrapped around the top of the support 604.

[0089] In this embodiment, the silicone anti-slip sleeve 614 is first fixedly covered on the top of the tray 604. The silicone anti-slip sleeve 614 can ensure that the pallet will not slip due to inertia when it is placed on the top of the tray 604. At the same time, the silicone anti-slip sleeve 614 can be combined with the anti-slip texture on the bottom of the pressure plate 613 to form a double anti-slip design, which can ensure that the goods will not shift in position during subsequent movement.

[0090] In some embodiments, the four hydraulic cylinders 602 can convert hydraulic energy into mechanical energy to drive the support platform 604 to make linear motion, and the four hydraulic push rods 611 can convert hydraulic energy into mechanical energy to drive the four pressure plates 613 to make linear motion.

[0091] In this embodiment, four hydraulic cylinders 602 can push the platform 604 to rise along the slide column 605, and the synchronous movement of the four hydraulic cylinders 602 can ensure the stability of the platform 604 during lifting and lowering, and avoid the tilting of the goods. At the same time, the four hydraulic push rods 611 can calculate the distance of descent of the pressure plate 613 based on the laser sensor data, and drive the four hydraulic push rods 611 to make the four pressure plates 613 slowly descend. When the pressure plate 613 contacts the top of the goods on the pallet, the pressure sensor feeds back the clamping force. At this time, the system automatically fine-tunes to the optimal pressure, and the anti-slip texture fits tightly with the pallet surface to prevent horizontal displacement.
