Description

Technical Field

[0001] This utility model relates to the field of profile conveying and palletizing technology, specifically to an L-profile flipping and adjusting mechanism for a palletizing machine. Background Technology

[0002] After L-shaped profiles are processed, they need to be stored. Sometimes, due to their length and weight, manual handling and stacking are not only inefficient but also very labor-intensive. Therefore, people use palletizers for automatic stacking. However, existing palletizers can only stack flat. Due to the special structure of L-shaped profiles, after one layer is completed, it is impossible to continue stacking on top of it, resulting in low space utilization. Therefore, it is particularly important to design an L-shaped profile flipping and adjustment mechanism for palletizers to solve the above problems. Summary of the Invention

[0003] To solve the above problems, this utility model designs an L-shaped profile flipping and adjusting mechanism for a palletizing machine. By cooperating with a flipping motor, a linear motor and a clamping cylinder assembly, the L-shaped profile can be flipped and stacked on top of another L-shaped profile. This design not only improves space utilization, but also allows for stacking on top of another L-shaped profile after one layer has been stacked, thus increasing practicality.

[0004] To solve the above-mentioned technical problems, this utility model provides an L-shaped profile flipping and adjusting mechanism for a palletizing machine. The mechanism includes an auxiliary frame located at the front end of the main frame and adjusting robotic arms mounted on the auxiliary frame. One adjusting robotic arm is located at the top of each of the left and right ends of the auxiliary frame, with the two robotic arms facing each other. The adjusting robotic arms are connected to the auxiliary frame via robotic arm mounting seats. Each adjusting robotic arm consists of a flipping motor, a linear motor, a linear motor guide rail, a clamping cylinder assembly, and a mounting plate. The linear motor is vertically fixed to the robotic arm mounting seat via the linear motor guide rail. The mounting plate is slidably connected to the linear motor guide rail by the linear motor. The flipping motor is horizontally fixed to one side of the mounting plate, and the clamping cylinder assembly is rotatably connected to the other side of the mounting plate and connected to the output shaft of the flipping motor.

[0005] Furthermore, the robotic arm mounting seats on both sides are connected to the auxiliary frame via a position adjustment mechanism. The position adjustment mechanism consists of a first slide rail, a rotating shaft, a manual rotating wheel, a coupling, a lead screw, and a lead screw connecting nut structure located at the top of the left and right ends of the auxiliary frame. The rotating shaft is horizontally placed and rotatably connected to the auxiliary frame. Each end of the rotating shaft is connected to a lead screw via a coupling. The lead screw is also horizontally rotatably connected to the auxiliary frame. The robotic arm mounting seats on both sides are slidably connected to the first slide rails at the left and right ends of the auxiliary frame via first sliders at the bottom. The robotic arm mounting seats on both sides are connected to two lead screws via lead screw connecting nut structures at the bottom. The threads on the two lead screws are arranged in opposite directions. The manual rotating wheel is fitted at the center of the rotating shaft.

[0006] Furthermore, a first pulley conveyor and a second pulley conveyor are also provided on the auxiliary frame between the two robotic arm mounting bases. The first pulley conveyor and the second pulley conveyor are arranged one in front of the other. The rear end of the first pulley conveyor extends into the front end of the second pulley conveyor. Several partition blocks are evenly arranged on the transmission belt in the second pulley conveyor. The spacing between two adjacent partition blocks on the same transmission belt matches the width of the L-shaped profile.

[0007] Furthermore, a first photoelectric sensor and a second photoelectric sensor are respectively installed on the robotic arm mounting bases on both sides of the first and second pulley conveyors.

[0008] After adopting the above structure, the present invention has the following beneficial effects:

[0009] 1. This utility model can achieve the flipping of L-shaped profiles by using a flipping motor, a linear motor and a clamping cylinder assembly, and stack the flipped L-shaped profiles on top of another L-shaped profile. This design not only improves space utilization, but also allows stacking to continue on top of another L-shaped profile after one layer has been stacked, thus increasing practicality.

[0010] 2. This utility model allows the hand-grinding base plate to deform in both directions by adjusting the distance between the two grip structures, thereby matching the curvature of the car body and enabling it to smoothly complete the grinding work on different parts of the car body, thus increasing its practicality.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will be further described in detail below through specific embodiments.

[0020] like Figure 1 , Figure 2 and Figure 3The L-shaped profile flipping and adjusting mechanism for a palletizing machine shown includes an auxiliary frame 2 located at the front end of the main frame 1 and adjusting robotic arms mounted on the auxiliary frame. One adjusting robotic arm is located at the top of each of the left and right ends of the auxiliary frame, with the two sides facing each other. The adjusting robotic arms are connected to the auxiliary frame via robotic arm mounting bases 3. Each adjusting robotic arm consists of a flipping motor 4, a linear motor 5, a linear motor guide rail 6, a clamping cylinder assembly 7, and a mounting plate 8. The linear motor is vertically fixed to the robotic arm mounting base via the linear motor guide rail. The mounting plate is slidably connected to the linear motor guide rail by the linear motor drive. The flipping motor is horizontally fixed to one side of the mounting plate, and the clamping cylinder assembly is rotatably connected to the other side of the mounting plate and connected to the output shaft of the flipping motor. During operation, the linear motor first drives the lowering mounting plate, activating the clamping cylinder assemblies on both sides to clamp the L-shaped profile. Then, it rises to the initial position, and the flipping motor is activated to flip the L-shaped profile. When the next L-shaped profile moves directly below, the linear motor is activated to place the flipped L-shaped profile on top, forming a tetrahedral structure. Finally, the clamping cylinder assemblies are released to return to the initial state. This invention, through the cooperation of the flipping motor, linear motor, and clamping cylinder assemblies, can achieve the flipping of L-shaped profiles and the stacking of the flipped L-shaped profiles on top of another L-shaped profile. This design not only improves space utilization but also allows for stacking on top of one layer after another, thus increasing practicality.

[0021] like Figure 2 The robotic arm mounting seats on both sides are connected to the auxiliary frame via a position adjustment mechanism. This mechanism consists of a first slide rail 9 at the top of each end of the auxiliary frame, a rotating shaft, a manual rotating wheel 10, a coupling, a lead screw 11, and a lead screw connecting nut. The rotating shaft is horizontally positioned and rotatably connected to the auxiliary frame. Each end of the rotating shaft is connected to a lead screw via a coupling, and the lead screws are also horizontally rotatably connected to the auxiliary frame. The robotic arm mounting seats on both sides are slidably connected to the first slide rails at the left and right ends of the auxiliary frame via first sliders at their bottoms. The robotic arm mounting seats on both sides are connected to two lead screws via lead screw connecting nuts at their bottoms, with the threads on the two lead screws arranged in opposite directions. The manual rotating wheel is fitted at the center of the rotating shaft. This invention allows adjustment of the distance between the robotic arm mounting seats on both sides according to the length of the L-shaped profile, thereby changing the distance between the rotating robotic arms. This design enables the stacking of L-shaped profiles of different lengths.

[0022] like Figure 2The auxiliary frame between the two robotic arm mounting bases shown is also equipped with a first pulley conveyor 12 and a second pulley conveyor 13. The first and second pulley conveyors are arranged one in front of the other, with the rear end of the first pulley conveyor extending into the front end of the second pulley conveyor. Several partition blocks 14 are evenly arranged on the transmission belt of the second pulley conveyor, and the spacing between two adjacent partition blocks on the same transmission belt matches the width of the L-shaped profile. During operation, the L-shaped profile is first placed on the first pulley conveyor and then moved to the second pulley conveyor. At this point, the L-shaped profile is flipped and raised using a tilting and adjusting robotic arm assembly. When the next L-shaped profile passes by, the tilting and adjusting robotic arm assembly places the flipped L-shaped profile on top of it, forming a tetrahedral structure. The two L-shaped profiles of the tetrahedral structure continue to be conveyed under the action of the second pulley conveyor.

[0023] like Figure 2 A first photoelectric sensor 15 and a second photoelectric sensor 16 are respectively installed on the robotic arm mounting seats on both sides of the first and second pulley conveyors. This invention uses the first photoelectric sensor to detect the L-shaped profile being conveyed on the first pulley conveyor. When the first photoelectric sensor does not detect the L-shaped profile, it sends feedback to the PLC controller, which then reminds the operator to adjust the distance between the two robotic arm mounting seats, allowing the flipping and adjusting robotic arm assembly to smoothly clamp the L-shaped profile. When the second photoelectric sensor detects the L-shaped profile, the PLC controller activates the flipping and adjusting robotic arm assembly to perform flipping or stacking.

[0024] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
