Description

Technical Field

[0001] The present application relates to the field of handling equipment, and in particular to a palletizer. Background Art

[0002] In enterprise production, palletizing systems have a wide range of uses, and palletizing machines are one of the important devices for achieving automated production and ensuring high production efficiency.

[0003] In the related technology, such as publication number CN210794938U, the gantry palletizing equipment has the following working principle: the goods are placed between splint one and splint two, and then the piston rod of the horizontal linear drive structure retracts to drive splint two and the support plate to move horizontally toward the direction of the goods synchronously until the goods are clamped and fixed between splint one and splint two. When splint two is attached to the goods, the piston rod of the splint horizontal linear drive mechanism retracts, and at the same time, the piston rod of the horizontal linear drive mechanism continues to retract, which will cause the support plate to move horizontally and attach to splint two, so that the support hook of the support plate supports the bottom end of the goods, thereby realizing the handling and movement of the goods.

[0004] Regarding the above-mentioned related technologies, there is a defect that the second clamping plate approaches the first clamping plate in a linear motion, which leads to low clamping stability of the palletizer. Summary of the Invention

[0005] In order to improve the clamping stability of a palletizer, the present application provides a palletizer.

[0006] The present application provides a palletizer that adopts the following technical solution:

[0007] A palletizer, comprising:

[0008] frame;

[0009] A vertical moving assembly is arranged on the frame;

[0010] A horizontal moving component connected to the vertical moving component;

[0011] A clamping jaw frame connected to the horizontal moving assembly;

[0012] A fixed clamping plate, fixedly connected to the clamping jaw frame;

[0013] A swing rod is rotatably connected to the clamping jaw frame to form an active arm and a driven arm;

[0014] A movable clamping plate is connected to the driven arm of the swing lever and is used to move closer to or away from the fixed clamping plate by rotating;

[0015] A swing drive assembly is arranged on the clamping jaw frame, and the swing drive assembly is connected to the active arm of the swing rod.

[0016] By adopting the above technical solution, the movable clamping plate approaches or moves away from the fixed clamping plate through the rotation of the swing rod, so the movable clamping plate and the fixed clamping plate are rotated and clamped. Compared with the mobile clamping, the rotary clamping is easier to achieve a greater clamping force, thereby improving the clamping stability of the palletizer.

[0017] Preferably, the swing drive assembly includes an active slide, a swing motor, a driving screw and a transmission linkage. The active slide is horizontally slidably arranged on the clamping frame; the swing motor is arranged on the clamping frame; the driving screw is coaxially connected to the output shaft of the swing motor, and the driving screw is threaded through the active slide; the transmission linkage connects the active slide and the active arm of the swing rod, and is used to realize the movable clamping plate approaching or moving away from the fixed clamping plate through the reciprocating motion of the active slide.

[0018] By adopting the above technical solution, compared with the method of swinging the swing arm by rotation, this design method converts the linear motion of the active slide into the rotation of the swing arm. Among the two components of force formed by the resistance exerted by the swing arm on the active slide, one component is parallel to the movement direction of the active slide and hinders the active slide, and the other component is the pressure perpendicular to the movement direction of the active slide. This pressure must be converted into friction force to hinder the active slide, so that the active slide can drive the swing arm to move more smoothly.

[0019] Preferably, the swing rod is in the shape of a bent rod, and is used to make the active arm of the swing rod form an acute angle with the horizontal plane when the movable clamping plate clamps the workpiece; the transmission linkage includes a compression plate and an opening spring, the lower end of the compression plate is rotatably connected to the active slide, and the upper end of the compression plate is in contact with the active arm of the swing rod; the opening spring is respectively connected to the active slide and the compression plate, and is used to allow the compression plate to press down the active arm of the swing rod with the help of the elastic force of the opening spring when the active slide is away from the swing rod.

[0020] By adopting the above technical solution, compared with the connecting rod structure between the active slide and the swing arm, this design method will not generate resistance to the active slide when the movable clamp plate moves away from the fixed clamp plate, so the smoothness of the active slide driving the swing arm can be improved.

[0021] Preferably, the active slide is provided with an ejection extension plate, which is extended in the direction close to the swing rod, and the ejection extension plate is provided with a closing positioning wheel, which is in contact with the upper end of the swing rod, and the closing positioning wheel is in contact with the side of the swing rod away from the workpiece.

[0022] By adopting the above technical solution, after the swing rod abuts against the closing positioning wheel, the active slide cannot continue to move forward, so it is not easy for the movable clamping plate to over-press the clamped workpiece, and the workpiece will not be damaged during the transportation process.

[0023] Preferably, the swing arm is hinged to a side of the movable clamping plate away from the fixed clamping plate, and the swing arm and the movable clamping plate rotate at a fixed angle.

[0024] By adopting the above technical solution, when the movable clamping plate clamps the workpiece, an angle can be formed between the swing rod and the movable clamping plate to adapt to the workpiece with different angles between the side and the horizontal plane.

[0025] Preferably, the vertical moving component and the horizontal moving component have the same structure and both include a movable slide, a fixed rack, a movable motor and a movable gear. The movable slide is slidably arranged, the fixed rack is fixedly arranged, the movable motor is arranged on the movable slide, the movable gear is connected to the output shaft of the movable motor, and the movable gear is meshed with the fixed rack.

[0026] By adopting the above technical solution, the moving motor is started to rotate the moving gear. During the rotation process, the moving gear can cooperate with the fixed rack to move the movable slide, thereby realizing vertical movement and horizontal movement.

[0027] Preferably, a rotary swing arm and a rotary drive member are provided between the clamping jaw frame and the horizontal moving assembly, one end of the rotary swing arm is rotatably connected to the movable slide of the horizontal moving assembly, and the other end is provided for the clamping jaw frame to be set; the rotary drive member is provided on the movable slide of the horizontal moving assembly, and the rotary drive member is used to rotate the rotary swing arm.

[0028] By adopting the above technical solution, with the help of a rotary drive component and a rotary swing arm, the transport path of the workpiece can be made more diversified.

[0029] Preferably, the clamping jaw frame is rotatably connected to the rotary swing arm, and the rotary swing arm is provided with a self-rotation driving member, and the self-rotation driving member is used to make the clamping jaw frame rotate.

[0030] By adopting the above technical solution and with the help of the self-rotating drive member, the transportation method can be further enriched.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The movable clamping plate moves closer to or away from the fixed clamping plate by rotating the swing rod, so the movable clamping plate and the fixed clamping plate are clamped in a rotating manner. Compared with the movable clamping, the rotating clamping is easier to achieve a greater clamping force, thereby improving the clamping stability of the palletizer;

[0033] 2. Compared to the method of swinging the swing arm by rotation, this design converts the linear motion of the active slide into the rotation of the swing arm. The swing arm then exerts resistance on the active slide, creating two force components. One component is parallel to the active slide's direction of motion, hindering it, while the other component is a pressure force perpendicular to the active slide's direction of motion. This pressure force must be converted into friction to hinder the active slide, allowing the active slide to drive the swing arm's movement more smoothly.

[0034] 3. Compared with the connecting rod structure between the active slide and the swing arm, this design method does not generate resistance to the active slide when the movable clamp plate moves away from the fixed clamp plate, thereby improving the smoothness of the active slide driving the swing arm.

[0040] The following is combined with Figure 1-4 This application is described in further detail.

[0041] The embodiment of the present application discloses a palletizer.

[0042] Reference Figure 1 and Figure 2The palletizer includes a frame 1, a vertical moving component 2, a horizontal moving component 3, a clamping frame 4, a fixed clamping plate 41, a swing rod 5, a movable clamping plate 42 and a swing drive component 6. The vertical moving component 2 is arranged on the frame 1, and the vertical moving component 2 can move the components up and down; the horizontal moving component 3 is connected to the vertical moving component 2, and the horizontal moving component 3 can allow the components to move horizontally relative to the vertical moving component 2; the clamping frame 4 is connected to the horizontal moving component 3; the fixed clamping plate 41 is fixedly connected to the clamping frame 4; the swing rod 5 is rotatably connected to the clamping frame 4 to form an active arm 51 and a driven arm 52; the movable clamping plate 42 is connected to the driven arm 52 of the swing rod 5, so that the movable clamping plate 42 can be moved closer to or away from the fixed clamping plate 41 by rotation; the swing drive component 6 is arranged on the clamping frame 4, and the swing drive component 6 is connected to the active arm 51 of the swing rod 5.

[0043] Reference Figure 1 and Figure 2 In this embodiment, the movable clamping plate 42 approaches or moves away from the fixed clamping plate 41 by rotating the swing rod 5, so the movable clamping plate 42 and the fixed clamping plate 41 are rotated and clamped. Compared with the movable clamping, the rotary clamping is easier to achieve a greater clamping force, thereby improving the clamping stability of the palletizer.

[0044] Reference Figure 1 and Figure 2 In order to make the movement of the swing rod 5 smoother, the following settings are correspondingly arranged. First, the swing drive assembly 6 includes an active slide 61, a swing motor 62, a driving screw 63 and a transmission linkage 64. The active slide 61 is horizontally slidably arranged on the clamping claw frame 4; the swing motor 62 is arranged on the clamping claw frame 4; the driving screw 63 is coaxially connected to the output shaft of the swing motor 62, and the driving screw 63 is threaded through the active slide 61; the transmission linkage 64 connects the active slide 61 and the active arm 51 of the swing rod 5, which is used to convert the reciprocating motion of the active slide 61 into the rotation of the swing rod 5, so as to make the movable clamping plate 42 approach or move away from the fixed clamping plate 41.

[0045] Reference Figure 1 and Figure 2 When the active slide 61 drives the swing rod 5, the swing rod 5 exerts resistance on the active slide 61 to form two components of force. One component is parallel to the movement direction of the active slide 61 and hinders the active slide 61. The other component is a pressure perpendicular to the movement direction of the active slide 61. This pressure must be converted into friction to hinder the active slide 61, so that the active slide 61 can drive the swing rod 5 to move more smoothly.

[0046] Reference Figure 1 and Figure 2When the movable clamping plate 42 is moved away from the fixed clamping plate 41, the upper end of the compression plate 641 is pressed against the upper end of the active slide 61, and the upper end of the compression plate 641 is pressed against the upper end of the active slide 61.

[0047] In addition, in this embodiment, when the active slide 61 approaches the swing rod 5, the compression plate 641 will also normally push the active arm 51 of the swing rod 5, so that the active slide 61 can normally drive the swing rod 5 to swing back and forth.

[0048] Reference Figure 1 and Figure 2 In order to prevent the movable clamping plate 42 from over-pressing the workpiece, the following settings are correspondingly provided. The active slide 61 is provided with a pushing extension plate 611. The pushing extension plate 611 is extended in the direction close to the swing rod 5. The pushing extension plate 611 is provided with a closing positioning wheel 612. The closing positioning wheel 612 is in contact with the upper end of the swing rod 5. The closing positioning wheel 612 is in contact with the side of the swing rod 5 away from the workpiece. The closing positioning wheel 612 can be set at a predetermined position so that after the swing rod 5 is in contact with the closing positioning wheel 612, the active slide 61 cannot continue to move forward, so that it is not easy for the movable clamping plate 42 to over-press the clamped workpiece, and thus the workpiece will not be damaged during the transportation process.

[0049] Reference Figure 1 and Figure 2 In order to adapt to the situation where the side of the workpiece is at different angles with the horizontal plane, the swing arm 5 is hinged to the side of the movable clamping plate 42 away from the fixed clamping plate 41, and the swing arm 5 and the movable clamping plate 42 can rotate at a fixed angle. Specifically, a seat body is provided on the side of the movable clamping plate 42 away from the workpiece, and the seat body is provided with a groove. The driven arm 52 of the swing arm 5 is rotatably set in this groove, so as to achieve the purpose of fixed angle rotation between the swing arm 5 and the movable clamping plate 42.

[0050] Reference Figure 1 and Figure 3In this embodiment, the structure of the vertical moving assembly 2 is consistent with that of the horizontal moving assembly 3. For the convenience of expression, the accompanying drawings show the structure of the vertical moving assembly 2. Specifically, the vertical moving assembly 2 and the horizontal moving assembly 3 both include a movable slide 7, a fixed rack 71, a moving motor 72 and a moving gear 73. The movable slide 7 is slidingly arranged. In the vertical moving assembly 2, the movable slide 7 slides relative to the frame 1, while in the horizontal moving assembly 3, the movable slide 7 slides relative to the movable slide 7 of the vertical moving assembly 2. The fixed rack 71 is fixedly arranged. In component 2, the fixed rack 71 is fixed on the frame 1. In the horizontal moving component 3, the fixed rack 71 is fixed on the movable slide 7 of the vertical moving component 2. The moving motor 72 is set on the movable slide 7. The moving gear 73 is connected to the output shaft of the moving motor 72. The moving gear 73 is engaged with the fixed rack 71. When working, start the moving motor 72 to rotate the moving gear 73. During the rotation process, the moving gear 73 can cooperate with the fixed rack 71 to make the movable slide 7 move, thereby realizing vertical and horizontal movement.

[0051] Reference Figure 1 and Figure 4 In order to further enrich the workpiece transportation path, the following settings are correspondingly provided. First, a rotary swing arm 8 and a rotary driving component 81 are provided between the clamping jaw frame 4 and the horizontal moving component 3. One end of the rotary swing arm 8 is rotatably connected to the movable slide 7 of the horizontal moving component 3, and the other end is provided for the clamping jaw frame 4 to be set. The rotary driving component 81 is set on the movable slide 7 of the horizontal moving component 3, and the rotary driving component 81 will cause the rotary swing arm 8 to rotate; second, the clamping jaw frame 4 is rotatably connected to the rotary swing arm 8, and the rotary swing arm 8 is provided with a self-rotation driving component 9, which will cause the clamping jaw frame 4 to rotate.

[0052] In this embodiment, the rotary drive member 81 and the rotation drive member 9 have the same structure, and both achieve rotation through the cooperation of the motor and the gear.

[0053] The implementation principle of a palletizer in an embodiment of the present application is as follows: the movable clamping plate 42 approaches or moves away from the fixed clamping plate 41 by rotating the swing rod 5, so the movable clamping plate 42 and the fixed clamping plate 41 are rotationally clamped. Compared with mobile clamping, rotational clamping is easier to achieve a greater clamping force, thereby improving the clamping stability of the palletizer.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
