[0001] The invention relates to the technical field of C and Z-shaped steel palletizing, in particular to an automatic C and Z-shaped steel palletizing machine. Background Art

[0002] Due to the particularity of C-shaped steel and consideration of convenient transportation, they should be stacked in one group facing forward and the other in reverse, and the notches should be engaged. All companies producing C and Z-shaped steel on the market use manual handling to stack the profiles. The general specifications of C-shaped steel are between 80, 100, 120, 160, 180, 200, 220, 250, 280, and 300. The general specifications of Z-shaped steel are between 180, 200, 220, 250, and 300. Manual handling of smaller models is ok, but taking 300-shaped steel as an example, it is very difficult to carry, with a weight of about 11KG per meter. The length of each piece is uncertain, generally between 6-9 meters, and the weight of each piece is between 66-99KG. It requires multiple people to cooperate in the handling and turn over the C and Z-shaped steels before they can be stacked.

[0036] 1. For this C and Z steel automatic palletizer, when the profile is cut and transferred to the surface of the conveying roller, if it does not need to be turned over, the first turning arm is vertical to the ground to facilitate the picking device to grab the material, and at the same time, half of the second turning arm is located below the profile, that is, waiting below the upper plane of the conveying roller to avoid blocking the profile transmission.

DETAILED DESCRIPTION

[0046] See also Figures 1 to 5 The present invention provides a technical solution: C, Z-shaped steel automatic palletizer, including:

[0047] The main frame 1 is formed by welding rectangular tubes;

[0048] The conveying frame 2 is fixedly mounted on the bottom of the main frame 1, and a conveying roller 3 is arranged on the surface of the conveying frame 2;

[0049] The conveyor frame 2 also includes:

[0050] A first turning motor 4 is fixed to the middle of the side of the conveying frame 2;

[0051] A first turning shaft 5 connected to the top of the side of the conveying frame 2;

[0052] A first flip arm 6, which is sleeved and mounted on the surface of the first flip shaft 5;

[0053] A second turning motor 7, which is fixed to the bottom of the side of the conveying frame 2;

[0054] A second flip shaft 8 connected to a side surface of the second flip motor 7;

[0055] A second flip arm 9, which is sleeved on the outer wall of the second flip shaft 8;

[0056] The main frame 1 also includes:

[0057] The advance and retreat shaft 10 is fixed to the top of both sides of the main frame 1;

[0058] A sliding wheel set 11 connected to the surface of the advance and retreat shaft 10;

[0059] A lifting shaft 12 connected to the inside of the sliding wheel set 11;

[0060] A grabbing beam 13, which is mounted at the bottom of the lifting shaft 12;

[0061] A pick-up device 14 connected to the surface of the grab beam 13;

[0062] A pickup device 15 connected to the bottom of the pickup device 14;

[0063] The conveying rollers 3 are equidistantly distributed on the surface of the conveying frame 2, and the conveying rollers 3 rotate in the same direction through the motor. The conveying rollers 3 convey the profiles through the same direction rotation of the motor. When the profiles are completely located on the surface of the conveying rollers 3, it is convenient to turn over or clamp and stack the profiles.

[0064] The first flip shaft 5 is movably connected to the conveying frame 2, and the first flip shaft 5 is connected to the first flip motor 4 through a transmission chain. When the profile is cut and conveyed to the surface of the conveying roller 3, if it does not need to be flipped, the first flip arm 6 is vertical to the ground to facilitate the picking device 14 to grab the material. At the same time, half of the second flip arm 9 is located below the profile, that is, below the position of the upper plane of the conveying roller 3 to wait, so as to avoid blocking the transmission of the profile;

[0065] The second flip arm 9 is movably connected to the first flip shaft 5, and the second flip arm 9 is connected to the second flip shaft 8 through a transmission chain, and a cross-shaped structure is formed between the second flip arm 9 and the first flip arm 6. When the profile needs to be flipped, the first flip arm 6 is driven by the first flip motor 4 to drive the first flip shaft 5 to rotate clockwise, and the second flip arm 9 is driven by the second flip motor 7 to drive the second flip shaft 8 to rotate counterclockwise, so that the profile is clamped between the second flip arm 9 and the first flip arm 6, so as to turn the profile over to prevent the profile from falling off during the turning process, wherein the second flip arm 9 is movably connected to the first flip shaft 5 to prevent the second flip arm 9 and the first flip arm 6 from rotating in opposite directions to cause a conflict;

[0066] The first flip arm 6 forms a rotating structure through the first flip shaft 5 and the first flip motor 4, and the second flip arm 9 and the first flip arm 6 rotate towards each other, and the central axis of the second flip arm 9 coincides with the central axis of the first flip arm 6. The second flip arm 9 and the first flip arm 6 rotate towards each other at the beginning. After clamping the profile, the second flip arm 9 rotates clockwise synchronously with the first flip arm 6 to realize the turning over of the profile, which is conducive to realizing the automatic turning over of the profile;

[0067] The first flip arm 6 also includes but is not limited to:

[0068] A telescopic spring rod 16, which is arranged inside the first flip arm 6;

[0069] An elastic torsion spring 17 connected to one end of the telescopic spring rod 16;

[0070] A clamping member 18 fixed to the outside of the elastic torsion spring 17;

[0071] a suction cup 19 connected to the surface of the clamping member 18;

[0072] The clamping member 18 forms a movable structure through the elastic torsion spring 17 and the telescopic spring rod 16, and the clamping member 18 is a double hook structure. When the second flip arm 9 and the first flip arm 6 clamp the columnar profile, the clamping member 18 is squeezed by the profile and rotates outward through the elastic torsion spring 17 and has elasticity through the telescopic spring rod 16, so that the profile is squeezed between the clamping members 18. At this time, the clamping member 18 with a double hook structure automatically resets to clamp the profile, thereby preventing the profile from rolling down during the flipping process;

[0073] The clamping member 18 forms an elastic structure with the first flip arm 6 through the telescopic spring rod 16, and the surface of the clamping member 18 is planar;

[0074] The telescopic spring rod 16 is evenly distributed on the surface of the first flip arm 6, and one end of the telescopic spring rod 16 protrudes from the surface of the first flip arm 6. The second flip arm 9 is also provided with a telescopic spring rod 16, an elastic torsion spring 17, a clamping member 18 and a suction cup 19. The telescopic spring rod 16 inside the second flip arm 9 and the telescopic spring rod 16 inside the first flip arm 6 are staggered. The surface of the clamping member 18 is planar and fixed with a suction cup 19. The suction cup 19 can be adsorbed on the surface of the sheet profile, which is conducive to adsorbing and clamping the sheet profile for flipping. The suction cup 19 cooperates with the clamping member 18 to clamp the steel bars respectively. The columnar steel bar part of the truss plate and the plate surface part of the adsorbed steel bar truss plate can realize the clamping and flipping of the steel bar truss plate, so as to facilitate its neat stacking. When stacking the profiles, the picking device 14 carries the picking device 15 to slide along the advance and retreat axis 10 and the surface of the grabbing beam 13 to adjust the horizontal position to facilitate the accurate adsorption of the profiles. The picking device 14 can carry the picking device 15 to be lifted and lowered through the lifting axis 12, so as to facilitate the stacking of the profiles. The picking device 15 is threadedly connected to the picking device 14, which is convenient for switching according to the shape of the profile, so as to stably clamp and adsorb various types of profiles.

[0075] In summary, when the C and Z steel automatic palletizer is used, first, when the profile is cut and transmitted to the surface of the conveying roller 3, if it does not need to be turned over, the first turning arm 6 is vertical to the ground to facilitate the picking device 14 to grab the material, and at the same time, half of the second turning arm 9 is located below the profile, that is, below the position of the upper plane of the conveying roller 3 to wait, so as to avoid blocking the transmission of the profile;

[0076] Then, the motor-driven sliding wheel set 11 arranged on the surface of the advance and retreat shaft 10 slides along the advance and retreat shaft 10. Similarly, the picking device 14 carries the picking device 15 to slide along the surface of the grabbing beam 13 until the picking device 15 is located above the profile. Then, the motor-driven lifting shaft 12 first descends and then rises to adsorb the profile to separate it from the surface of the conveying roller 3. Then, the profile is carried to the designated position by sliding along the surface of the grabbing beam 13, and the profile is put down to complete the stacking.

[0077] If the profile needs to be turned over, the first turning arm 6 is driven by the first turning motor 4 to drive the first turning shaft 5 to rotate clockwise, and the second turning arm 9 is driven by the second turning motor 7 to drive the second turning shaft 8 to rotate counterclockwise, so that the profile is clamped between the second turning arm 9 and the first turning arm 6;

[0078] Then, after clamping the profile, the second flip arm 9 rotates clockwise synchronously with the first flip arm 6 to realize turning over the profile, which is conducive to realizing automatic turning over of the profile. At this time, the operation of adsorbing the profile is repeated to stack the profile neatly;

[0079] Among them, the second flip arm 9 and the first flip arm 6 have different clamping modes according to different shapes of the profiles. When the profile is a columnar profile, the clamping member 18 is squeezed by the profile and rotates outwards through the elastic torsion spring 17 and has elasticity through the telescopic spring rod 16 when the second flip arm 9 and the first flip arm 6 rotate, so that the profile is squeezed between the clamping members 18. At this time, the clamping member 18 with a double hook structure automatically resets to clamp the profile, thereby preventing the profile from rolling down during the flipping process. Since the clamping member 18 is rotatable, when the profile is moved by the pickup device 15, the clamping member 18 is rotated by force, which can facilitate the profile to be detached from the clamp. A supporting member such as a cylinder can also be arranged. Depending on the material to be flipped, the supporting member may or may not be arranged, but it is also within the scope of the rights.

[0080] When the profile is a sheet profile or a plate profile, the surface of the clamping member 18 is flat and fixed with a suction cup 19, which can be adsorbed on the surface of the sheet profile, so as to facilitate adsorption and clamping of this type of profile for turning over, and the suction cup 19 cooperates with the clamping member 18 to respectively clamp the columnar steel bar part of the steel bar truss plate and adsorb the plate surface part of the steel bar truss plate, thereby achieving the clamping and turning of the steel bar truss plate, so as to facilitate its neat stacking;

[0081] Finally, the picking device 15 is threadedly connected to the picking device 14, which is convenient for switching according to the shape of the profile, so as to stably clamp and adsorb various types of profiles.
