Description

Technical Field

[0001] The utility model belongs to the technical field of coil production, and in particular relates to a buffer support structure of a coil stacking and turning machine. Background Art

[0002] Most existing palletizers in coil workshops rely on servo motors for turning and positioning. The top plate of these palletizers is fully supported by a lifting cylinder. The impact force generated by the coils falling from the lifting tracks onto the top plate is fully applied to the lifting cylinder below the top plate. Under the constant impact of the coils, the detection signal from the cylinder's magnetic ring switch is often lost, causing the palletizer to malfunction or malfunction. The lifting cylinders, subjected to the constant impact of falling coils, gradually reduce their service life, leading to frequent malfunctions and increased maintenance costs. Utility Model Content

A rotatable connecting rod is hinged between the support plates. A support head is installed at the top of the connecting rod. A connecting plate is provided on the side wall of the lower half of the connecting rod. A mounting seat is installed at the other end of the crossbeam.

[0015] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to facilitate understanding by technicians.

[0016] The utility model discloses a buffer support structure of a coiled material stacking and turning machine, which mainly includes a mounting seat 1, a buffer cylinder 2, a support seat 3, a connecting rod 4, a crossbeam 5, and a support head 7. The crossbeam 5 is installed on the frame of the stacking and turning machine and is located just below the top plate. A support seat 3 is installed at one end of the crossbeam 5. The support seat 3 includes a base plate 301 and a support plate 302. The base plate 301 is installed on the crossbeam 5 by bolts. Two groups of support plates 302 are provided on the base plate 301. A rotatable connecting rod 4 is hinged between the support plates 302. A support head 7 is installed at the top of the connecting rod 4. A connecting plate 401 is provided on the side wall of the lower half of the connecting rod 4. A mounting seat 1 is installed at the other end of the crossbeam 5. The tail end of the buffer cylinder 2 is hinged on the mounting seat 1, and the piston rod end of the buffer cylinder 2 is hinged on the connecting plate 401.

[0017] During operation, the top plate is lifted to an inclined state through the action of the bottom lifting cylinder 6. At this time, the buffer cylinder 2 and the lifting cylinder 6 act synchronously, and the piston rod of the buffer cylinder 2 extends synchronously, pushing the connecting rod 4 to rotate around the hinge point on the support plate 302, so that it stands upright and contacts the bottom surface of the top plate through the support head 7 (slightly lifted state). The coils fall onto the top plate in turn, so that the impact force of the coils falling onto the top plate is all applied to the connecting rod 4. The lifting cylinder 6 on the stacking turning machine no longer bears the impact force when the coils fall, thereby ensuring the reliability of the detection signal and reducing The situation in which the detection signal of the magnetic ring switch of the jacking cylinder 6 is lost due to the impact force is eliminated, thereby improving the reliability of the operation of the palletizer and reducing the failure rate of the palletizer. At the same time, the wear of the jacking cylinder 6 is effectively reduced, its service life is extended, and the maintenance cost and downtime are reduced; when all the single-row coils enter the top plate, the bottom jacking cylinder is reset and drives the top plate to descend. At this time, the piston rod of the buffer cylinder 2 retracts, driving the connecting rod 4 to rotate in the opposite direction, so that the support head 7 at its top is separated from the bottom of the top plate, and the buffer cylinder 2 and the connecting rod 4 do not participate in the flipping.

[0018] The support head 7 is set to a U-shaped structure, and a threaded rod 8 is set at the bottom of the support head 7, and the threaded rod 8 is threadedly connected to the top of the connecting rod 4; the contact force between the support head 7 and the bottom of the top plate can be adjusted by adjusting the height of the threaded rod 8 to ensure that the support head 7 has sufficient supporting force.

[0019] The support head 7 is provided with a roller 9 for reducing the friction between it and the bottom of the top plate; the use of the roller 9 converts sliding friction into rolling friction, reducing the friction between the support head 7 and the bottom surface of the top plate, thereby reducing the movement resistance.

[0020] The connecting plate 401 and the connecting rod 4 are both provided with a limiting hole 4011 for connecting the piston rod of the buffer cylinder 2; the connection position of the piston rod of the buffer cylinder 2 and the limiting hole 4011 can be adjusted as needed to adapt to different buffering force requirements.

[0021] Working process:

[0022] During operation, the top plate is lifted to an inclined state through the action of the bottom lifting cylinder 6. At this time, the buffer cylinder 2 and the lifting cylinder 6 act synchronously, and the piston rod of the buffer cylinder 2 extends synchronously, pushing the connecting rod 4 to rotate around the hinge point on the support plate 302, so that it stands upright and contacts the bottom surface of the top plate through the support head 7 (slightly lifted state). The coils fall onto the top plate in turn, so that the impact force of the coils falling onto the top plate is all applied to the connecting rod 4. The lifting cylinder 6 on the stacking turning machine no longer bears the impact force when the coils fall, thereby ensuring the reliability of the detection signal and reducing The situation in which the detection signal of the magnetic ring switch of the jacking cylinder 6 is lost due to the impact force is eliminated, thereby improving the reliability of the operation of the palletizer and reducing the failure rate of the palletizer. At the same time, the wear of the jacking cylinder 6 is effectively reduced, its service life is extended, and the maintenance cost and downtime are reduced; when all the single-row coils enter the top plate, the bottom jacking cylinder is reset and drives the top plate to descend. At this time, the piston rod of the buffer cylinder 2 retracts, driving the connecting rod 4 to rotate in the opposite direction, so that the support head 7 at its top is separated from the bottom of the top plate, and the buffer cylinder 2 and the connecting rod 4 do not participate in the flipping.

[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
