Description

Technical Field

[0001] This application relates to the field of palletizer technology, for example to a support arm drive device and a palletizer. Background Technology

[0002] The descriptions in this section are provided only as background information relating to this disclosure and do not constitute prior art.

[0003] As a core piece of equipment in industrial automated production lines, palletizers function by precisely moving their arms to collect and transfer materials between the infeed and outfeed ends. In existing technologies, the arms typically rely on multi-axis guide rail systems (such as X / Y / Z directions) for motion control, and their movement range needs to cover the entire process of material gripping, stacking, and placement. However, the traditional palletizer arm design has the following significant drawbacks: to ensure the arms can lift and slide horizontally between the infeed and outfeed ends, the distance between them must be greater than the length of the arms themselves. This design results in high requirements for factory space, making it difficult to meet installation needs, especially in small and medium-sized factories or compact production lines. For example, fixed-length arms can easily interfere with equipment or building structures in narrow spaces, limiting the applicability of palletizers. Summary of the Invention

[0004] This application provides a support arm drive device, which couples the horizontal sliding of the upper support with the horizontal rotation (around the Z-axis) of the support arm through a linkage design of the transmission shaft, gear plate, and rack. This allows the support arm to rotate 90° or other angles before moving up and down, significantly reducing the required front-to-back distance between the feeding and discharging ends. This application also provides a palletizer that achieves all the technical effects of the support arm drive device.

[0005] In a first aspect, a support arm drive device and a palletizer are provided, including:

[0048] Combination Figure 1-4 As shown, this disclosure provides a support arm drive device, including:

[0049] Mounting bracket 11 is used to install and fix various components; mounting bracket 11 is a metal bracket.

[0050] The drive shaft 12 is rotatably mounted on the mounting bracket 11 along the Z-axis. The drive shaft 12 is connected to the mounting bracket 11 through a bearing seat, and a first gear 18 and a second gear are provided at both ends. The Z-axis can be defined according to actual needs and can be other directions.

[0051] The upper bracket 13 is slidably mounted in a direction perpendicular to the Z-axis. One side of the upper bracket 13 is engaged with the first gear 18 via the first rack 17. There are various ways to slide the upper bracket 13. For example, a groove or rail can be provided on a horizontal plane of the mounting bracket 11 to engage with the upper bracket 13. Alternatively, the groove or rail can be mounted on another component, as long as the sliding direction is perpendicular to the Z-axis. In the figure, the upper bracket 13 is an L-shaped metal plate. Its planar part is connected to the second slider, and its vertical part is connected to the first rack 17. The first rack 17 meshes with the first gear 18.

[0052] The first linear drive mechanism 14 is connected to the mounting bracket 11 and the upper bracket 13 respectively, and drives the upper bracket 13 to move along its sliding direction; the first linear drive mechanism 14 can be a cylinder, an electric telescopic rod, a hydraulic telescopic rod, etc., and the figure shows a cylinder.

[0053] The gear 16 is rotatably mounted on the mounting bracket 11 and meshes with the second gear. The gear 16 can be a full-tooth gear, or a gear 16 with 1 / 4 tooth, 1 / 2 tooth, etc., can be selected according to the rotation angle required by the support arm 15. The gear 16 can be connected to the mounting bracket 11 through bearings.

[0054] Support arm 15 is connected to gear plate 16. Support arm 15 is connected to gear plate 16 directly or indirectly.

[0055] Through the linkage design of the drive shaft 12 with the gear plate 16 and the rack, the horizontal sliding of the upper bracket 13 is coupled with the horizontal rotation (around the Z-axis) of the support arm 15, so that the support arm 15 can rotate 90° or other angles before moving up and down, which significantly shortens the front and rear distance requirements between the feeding end and the discharging end.

[0056] In some embodiments, the support arm 15 drive device further includes:

[0057] A crossbeam 19 is arranged along the Y-axis and slides with the mounting bracket 11; the crossbeam 19 is a rectangular metal beam extending along the Y-axis. The mounting bracket 11 has a U-shaped structure and is fitted onto the crossbeam 19.

[0058] The first slide rail 21 is mounted on the crossbeam 19, and a first slider and a second slider are mounted on it. The first slider is connected to the mounting bracket 11, and the second slider is connected to the upper bracket 13. The direction of the first slide rail 21 is the same as the extension direction of the crossbeam 19.

[0059] Positioning element 22 is mounted on mounting bracket 11 to limit the relative position of mounting bracket 11 and crossbeam 19. Positioning element 22 can be a bolt with a handle, which is threaded to mounting bracket 11. When positioning element 22 is tightened, the bolt part presses against crossbeam 19 to complete positioning.

[0060] In some embodiments, the upper support 13 includes:

[0061] When the upper bracket 13 approaches the mounting frame 11 to its minimum distance, it abuts against the mounting frame 11. In the figure, when the support arm 15 is positioned in the X-axis direction, the upper bracket 13 is closest to the mounting frame 11, and the abutment block 131 abuts against the mounting frame 11. When the first linear drive mechanism 14 begins to extend, the upper bracket 13 begins to move away from the mounting frame 11. The rack and pinion drive gear rotates, and the support arm 15 rotates synchronously. When the first linear drive mechanism 14 extends to its maximum stroke, the support arm 15 rotates 90° to the Y-axis direction, parallel to the crossbeam 19, greatly reducing the X-axis distance required for the support arm 15 when the crossbeam 19 moves up and down.

[0062] In some embodiments, the support arm 15 and the gear plate 16 are connected by a telescopic device 23, the telescopic device 23 comprising:

[0063] At least two vertical plates 231 are arranged in parallel longitudinally and connected to the gear disk 16 at the top. The two vertical plates 231 are connected to the gear disk 16 directly or at intervals. The upper end of the vertical plates 231 is connected to the fixing plate, and the fixing plate is connected to the gear disk 16.

[0064] Guide wheels 232 are spaced apart vertically, with both ends rotatably connected to the vertical plate 231, and the support arm 15 is slidably disposed in the intervals between them; there are at least three guide wheels 232, and four are disposed along the middle.

[0065] The second rack 234 is mounted on the support arm 15;

[0066] The drive motor 233 is mounted on the gear plate 16;

[0067] The third gear is fixedly mounted on the output shaft of the drive motor 233 and meshes with the second rack 234.

[0068] In some embodiments, the support arm 15 includes:

[0069] Two square steel bars are provided, spaced apart from each other, and the second rack 234 is located between the two square steel bars and is connected to them.

[0070] In some embodiments, the mounting bracket 11 has a U-shaped structure, with the crossbeam 19 slidably disposed on its inner side.

[0071] like Figure 5 This disclosure provides a palletizing machine, including: the support arm 15 driving device described in any of the above embodiments.

[0072] In some embodiments, the palletizer further includes:

[0073] Z-axis drive rail 24 is connected to mounting bracket 11 or crossbeam 19 and drives it to move in the Z-axis direction.

[0074] In some embodiments, the palletizer further includes:

[0075] The X-axis drive rail 25 is connected to the Z-axis drive rail 24 and drives it to move in the X-axis direction.
