Description

Technical Field

[0001] This application relates to the field of palletizing machine technology, and for example to a novel palletizing machine. 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] In the fields of automated production lines and warehousing logistics, palletizers (or stackers) are key equipment for realizing the automatic stacking of goods. They are used to neatly stack goods on pallets or other carriers according to preset rules to improve efficiency and save space.

[0004] Currently, the core structure of traditional palletizing machines widely used in the market typically includes a large frame for supporting and guiding moving parts. The most typical structural form is based on a "gantry" (or "gate-type") frame. In this design, the lifting device that carries the palletizing tools (such as support arms) needs to be mounted on a large, fixed gantry frame. This gantry frame is usually huge and structurally complex, and is an indispensable key component, its main function being to provide the necessary guide rails, support, and balance for the vertical movement (up and down) of the lifting device.

[0005] The shortcomings of existing technologies include: the portal frame structure requires a huge physical space for installation and operation, resulting in a significant increase in the overall size of the machine. The large frame structure involves a large amount of material usage, high manufacturing difficulty, and high transportation costs, leading to a high overall manufacturing cost. Due to its large size, this type of palletizer has very strict requirements for installation and operating space. In many space-constrained applications (such as limited factory interior space), traditional portal frame palletizers are simply impossible to install or operate properly. This greatly limits its application scope. Summary of the Invention

[0006] This application provides a novel palletizing machine that uses longitudinal support beams instead of a bulky gantry frame, significantly reducing the overall size of the machine and the required installation space, making it suitable for confined factory environments. The simplified frame structure reduces steel consumption, lowers processing difficulty and transportation costs, while also improving equipment deployment flexibility.

[0060] Combination Figure 1-6 As shown, this embodiment of the disclosure provides a method that uses longitudinal support beams 13 to replace the bulky gantry frame, significantly reducing the overall size of the machine and the requirements for installation space, making it suitable for confined factory environments. The simplified frame structure reduces steel usage, lowers processing difficulty and transportation costs, while also improving equipment deployment flexibility.

[0061] A novel palletizing machine includes: a support plate 18, a support beam 13, a first guide rail 19, a lifting frame 14, a support arm 15, a first sprocket 11, a first drive motor 16, a second sprocket 17, and a chain 12.

[0062] The support plate 18 can support and install components; optionally, the support plate 18 is a metal plate with a certain thickness.

[0063] A support beam 13 is longitudinally mounted on a support plate 18. Optionally, the support plate 18 and the support beam 13 are fixedly connected, such as by welding, and the connection can be reinforced by stiffening ribs. The support beam 13 can be made of square steel or H-beam steel, as long as it has two opposite sides. A limiting device can be installed on the support beam 13 to limit the rising height of the lifting frame 14. A proximity switch can be installed on the limiting device to detect whether the lifting frame 14 has reached the specified position.

[0064] The first guide rail 19 is longitudinally mounted on the support beam 13; it is fixed by bolts.

[0065] The lifting frame 14 is slidably mounted on the first guide rail 19; a slider is slidably mounted on the first guide rail 19, and the slider is fixedly connected to the lifting frame 14 by bolts. Optionally, the lifting frame 14 includes two opposing upright plates, a front side plate, and a left support beam 13. The upright plates are connected to the sliders on the two first guide rails 19, the front side of the upright plates is connected to the front side plate, and the front side plate and the left side of the upright plates are connected to the left support beam 13.

[0066] The support arm 15 is mounted on the lifting frame 14; optionally, the support arm 15 has two arms that are respectively connected to the left side of the left support beam 13 and the right side of the front side plate.

[0067] The first sprocket 11 is rotatably mounted on the top of the support beam 13; optionally, the front top of the support beam 13 is connected to a square tube, and a rotating shaft is rotatably mounted in the square tube, with the right side of the rotating shaft connected to the first sprocket 11.

[0068] The first drive motor 16 is mounted on the support plate 18; optionally, the first drive motor 16 is a motor with a reducer, which is fixed on the support plate 18.

[0069] The second sprocket 17 is mounted on the output shaft of the first drive motor 16 or rotatably mounted on the support beam 13 and driven to rotate by the first drive motor 16; optionally, the second sprocket 17 is mounted on the output shaft of the reducer.

[0070] Chain 12 is wound around the first sprocket 11 and the second sprocket 17, and its upper and lower ends are connected to the lifting frame 14. Chain 12 is suspended on the two sprockets. The rotation of the sprockets drives the chain 12 to move. When the chain 12 moves, it drives the lifting frame 14 and the support arm 15 to move up and down.

[0071] The first drive motor 16 drives the second sprocket 17 to rotate, and the chain 12 drives the lifting frame 14 to rise and fall along the first guide rail 19, thereby realizing the vertical movement control of the support arm 15.

[0072] In some embodiments, at least two first guide rails 19 are provided and are respectively disposed on two opposite sides of the support beam 13.

[0073] In some embodiments, the support plate 18 is mounted on the support platform 25 via a rotating assembly.

[0074] The rotating assembly can be controlled by a motor, a slewing bearing 22, or a geared disc. For example, the support plate 18 and the support platform 25 are rotatably connected by the slewing bearing 22, the geared disc is fixed on either the support plate 18 or the support platform 25, the motor is fixed on the other, and a gear is fixed to the motor output shaft, meshing with the geared disc. This method requires a controller to control the motor's running time or rotation speed.

[0075] In some embodiments, the rotating assembly includes:

[0076] The first toothed disc 21 is located at the bottom of the support plate 18; the first toothed disc 21 is a toothed disc with a larger diameter.

[0077] The slewing bearing 22 is connected at the top to the bottom of the first gear plate 21 or the support plate 18, and at the bottom to the support platform 25;

[0080] A linear telescopic mechanism 26 is mounted on a support platform 25, and its piston rod is connected to the first rack 23. The linear telescopic mechanism 26 can be a pneumatic cylinder, a hydraulic cylinder, an electric actuator, etc.

[0081] The rotating component is designed according to actual needs. For example, if the support arm 15 only needs to rotate 90° back and forth during operation, then a certain limiting component can be set on the support platform 25. The extension and retraction range of the limiting cylinder is within the range that makes the support plate 18 rotate 90°. Alternatively, a suitable cylinder model can be selected so that the extension and retraction stroke of the cylinder just makes the support plate 18 rotate 90°, thus eliminating the need to set a limiting component.

[0082] In some embodiments, the support platform 25 is mounted on the support frame 29 via a lateral sliding assembly, the lateral sliding assembly comprising:

[0083] The third guide rail 27 is horizontally arranged on the upper part of the support frame 29, and the support platform 25 is slidably arranged on the third guide rail 27;

[0084] The second rack 28 is connected to the support frame 29 and is arranged parallel to the third guide rail 27;

[0085] The second drive motor 31 is mounted on the support platform 25;

[0086] The second gear 32 is mounted on the output shaft of the second drive motor 31 and meshes with the second rack 28.

[0087] The support frame 29 includes two horizontally parallel metal square steels. The two square steels are connected to the side square steels on both sides. The control switch box 38 is set in a position that will not interfere with the movement of materials. The control switch on the control switch box 38 is connected to the controller and other components in the electrical control cabinet 37.

[0088] The optional rotating and lateral sliding components give the equipment dual degrees of freedom for horizontal rotation and lateral translation, enabling multi-pallet collaborative operation and covering blind spots that traditional fixed palletizers cannot reach.

[0089] In some embodiments, at least two third guide rails 27 are provided on the support frame 29 and are arranged parallel to each other.

[0090] In some embodiments, the support arm 15 is connected to the lifting frame 14 via an anti-pressure assembly, the anti-pressure assembly comprising:

[0091] Two connecting plates 36 are provided and spaced apart from each other, and are connected to the lifting frame 14 at the rear.

[0092] The rotating shaft is connected at one end to the rear end of the support arm 15 and at the other end to the connecting plate 36.

[0093] The pull rope 35 is connected at one end to the support arm 15 and at the other end to the lifting frame 14 via a length adjustment assembly.

[0094] The anti-pinch component automatically rotates upwards via the pull rope 35-rotating shaft when the support arm 15 presses down on the machine, materials, or personnel, preventing damage to goods or injury to personnel during the falling process.

[0095] In some embodiments, the length adjustment component includes:

[0096] The stud 34 is connected at one end to the pull rope 35; the pull rope 35 can be a chain 12, a wire rope, etc.

[0097] The fixed plate 33 is connected to the lifting frame 14 and has a through hole that allows the stud 34 to be inserted.

[0098] The nut is set on the stud 34.

[0099] In some embodiments, an electrical control cabinet 37 is provided on the support platform 25, and a control switch box 38 is provided on the support frame 29. The control switch box 38 is equipped with an emergency stop switch, start and stop operation control buttons, etc. The electrical control cabinet 37 is equipped with a controller, which is connected to all motors, cylinders, sensors and other equipment. For example, sensors that monitor the position of the support platform 25, sensors that monitor the angle of the support plate 18, and sensors that monitor the height of the lifting frame 14 can be set. Then, according to the needs of the production process, an automatic operation program is set to control the installation of the support arm 15 to move, realize material receiving, transfer, release, return, etc., and cyclical operation.
