Description

Technical Field

[0001] This utility model relates to lifting devices, and more particularly to a weighable automatic lifting device for metal pipeline coils. Background Technology

[0002] Copper and aluminum tube production lines are very common both domestically and internationally. After production, copper and aluminum tubes are usually coiled into circular coils. These coils are then transported to a weighing station for weighing, and the weighed coils are then stacked. While the handling and stacking processes are now automated, the weighing process still requires manual intervention. This creates a significant bottleneck in production. Furthermore, since copper and aluminum tube coils are typically heavy, manual weighing is inconvenient, time-consuming, and labor-intensive. This lack of manual intervention makes the process uncompetitive in industries that emphasize cost reduction and efficiency improvement, hindering large-scale promotion and industrial production.

[0008] Optionally, a position sensor is also included. The moving end of the palletizer is provided with a hollow guide post, and the outer ring of the load cell is provided with multiple fixing holes for connecting to the bottom end of the guide post.

The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0022] This specific embodiment details the weighable automatic lifting device for metal pipeline coils described in this application, such as... Figures 1-5 As shown, the weighable automatic lifting device for metal pipe coils includes: a mother plate 1, a fixed plate 2, a cylinder 3, a load cell 4, and a lifting device support plate 5. The cylinder 3 is fixed to the mother plate 1, and a cylinder rod 31 is installed through both the upper and lower ends of the cylinder 3. The cylinder rod 31 is vertical to the ground. The load cell 4 is annular and slidably sleeved on the top of the cylinder rod 31. The fixed plate 2 is fixed to the top of the cylinder rod 31 and is located above the load cell 4. The inner ring of the load cell 4 has a protruding detection end 41 on the side facing the fixed plate 2. The outer ring of the load cell 4 is fixed to the moving end of the palletizer. The lifting support plate 5 is connected to the bottom end of the cylinder rod 31 through a set of connecting rod structures. There are at least two lifting support plates 5. The lifting support plates 5 are evenly distributed around the cylinder rod 31. The lifting support plates 5 can extend into the inner circle of the metal pipe coil. The cylinder 3 can drive the cylinder rod 31 to move up and down and drive the connecting rod structure to extend or retract. The connecting rod structure can drive the lifting support plates 5 to move closer or further away from each other. The lifting support plates 5 can be tightly attached to the side wall of the inner circle of the metal pipe coil. The load cell 4 can be moved upward under the drive of the palletizer and the detection end 41 of the load cell 4 is tightly attached to the fixed plate 2. In operation, the palletizer drives the lifting support plate 5 to move to the inner ring of the metal pipe coil. Then, the cylinder 3 drives the lifting support plate 5 to move away from each other, so that the lifting support plate 5 is tightly attached to the inner wall of the inner ring of the metal pipe coil, thus fixing the metal pipe coil. Next, the palletizer drives the load cell 4 to move upwards, so that the detection end 41 of the load cell 4 is tightly attached to the fixed plate 2, pulling the metal pipe coil upwards until it is suspended in the air. During the lifting process, because the fixed plate 2 is always tightly attached to the detection end 41 of the load cell 4, and the bottom of the cylinder rod 31 connected to the fixed plate 2 is fixed to the metal pipe coil through the lifting support plate 5, the weight of the metal pipe coil can press on the detection end 41 of the load cell 4, thus achieving weighing of the metal pipe coil during the lifting process. This method has the advantage of being able to weigh the metal pipe coil during lifting. In this embodiment, the palletizer is existing technology, such as a gantry palletizer.

[0023] Optionally, this embodiment also includes a pull rod connecting seat 6. A first through hole is formed in the middle of the pull rod connecting seat 6. The top of the pull rod connecting seat 6 is fixed to the bottom surface of the mother plate 1. The cylinder rod 31 can slide through the first through hole, and the bottom end of the cylinder rod 31 can extend from the bottom end of the pull rod connecting seat 6. The connecting rod structure includes two movable connecting rods 7, a middle connecting rod 8, and an actuating pull rod 9. The two movable connecting rods 7 are spaced apart vertically. A fixed shaft 10 is fixed to the bottom end of the cylinder rod 31, and two connecting rod connecting seats 11 are spaced apart on the fixed shaft 10.

[0024] Optionally in this embodiment, the hanger support plate 5 is arc-shaped, the first bearing is located on the inner arc surface of the hanger support plate 5, and the outer arc surface of the hanger support plate 5 can closely adhere to the side wall of the inner ring of the metal pipeline coil. Setting the hanger support plate 5 to be arc-shaped allows the hanger support plate 5 to fit more closely to the inner ring of the metal pipeline coil.

[0025] Optionally in this embodiment, the fixed disk 2 has a ring of positioning platforms protruding on the side facing the detection end 41, and the positioning platforms can fit tightly against the detection end 41.

[0026] Optionally, this embodiment also includes a position sensor 12. The moving end of the palletizer is provided with a hollow guide post. The outer ring of the load cell 4 is provided with multiple fixing holes 42 for connecting to the bottom end of the guide post. The position sensor 12 and the load cell 4 are arranged adjacent to each other. When the fixed plate 2 and the detection end 41 of the load cell 4 are in close contact with each other, the position sensor 12 can be triggered. The top end of the cylinder rod 31 can extend into the guide post and move up and down inside the guide post.

[0027] Optionally in this embodiment, the weighing sensor 4 is a piezoresistive pressure sensor, the fixed disk 2 is made of magnetic material, and the position sensor 12 is a Hall sensor.

[0028] Optionally, this embodiment also includes a baffle, with at least two baffles. The baffles are evenly distributed around the cylinder rod 31. Each baffle includes a support 13 and an adjusting rod 14. The first end of the support 13 is fixed to the top surface of the mother plate 1. The adjusting rod 14 slides vertically through the second end of the support 13. The second end of the support 13 is provided with an adjusting and tightening handle 15, which can fix or loosen the adjusting rod 14. The bottom end of the adjusting rod 14 is provided with a rubber buffer pad 16. When the spreader support plate 5 extends into the inner ring of the metal pipe coil, the rubber buffer pad 16 can contact the top surface of the metal pipe coil. At this time, due to the obstruction of the rubber buffer pad 16, the spreader support plate 5 will no longer continue to descend, so as to avoid the position of the spreader support plate 5 being too low. When the thickness of the metal pipe coil changes, the user can adjust the height of the rubber buffer pad 16 according to the thickness of the metal pipe coil to ensure that the spreader support plate 5 is at a suitable height when the rubber buffer pad 16 contacts the top surface of the metal pipe coil. The specific operation procedure is to loosen the adjusting locking handle 15, then slide the adjusting rod 14 to adjust the height of the rubber buffer pad 16, and then fix the adjusting locking handle 15.

[0029] Optionally in this embodiment, the cylinder 3 is fixed to the top surface of the mother plate 1. The mother plate 1 is circular, and a second through hole coaxial with the first through hole is opened at the center of the mother plate 1. The cylinder rod 31 can slide through the second through hole. The cylinder 3 is a double-acting cylinder.

[0030] Optionally in this embodiment, the number of lifting support plates 5 is four, and the number of material stoppers is three.

[0031] Movement Process: First, the palletizer drives the weighing sensor 4 to move upward, causing the lifting device support plate 5 to be suspended in the air. At this time, the fixed plate 2 is placed on the detection end 41 of the weighing sensor 4 and is in close contact with the detection end 41. The position sensor 12 is triggered. At this time, the detection end 41 of the weighing sensor 4 carries the weight of the lifting device (hereinafter referred to as the lifting device for weighing automatic lifting devices used for metal pipe coils) in the unloaded state. The weighing sensor 4 detects the weight at this time and records it as the empty weight. Then, the palletizer moves the lifting device above the metal pipe coil and gradually... As the load cell moves downwards, the spreader support plate 5 extends into the inner ring of the metal pipe coil until the rubber buffer pad 16 contacts the top surface of the metal pipe coil. Meanwhile, the load cell 4 continues to move downwards under the drive of the palletizer until the fixed plate 2 and the detection end 41 move away from each other. At this point, the position sensor 12 is in a non-triggered state. Then, the cylinder 3 drives the cylinder rod 31 to move upwards, which in turn drives the fixed shaft 10 to move upwards. Driven by the fixed shaft 10, the movable connecting rod 7 gradually extends by the retraction device, causing the spreader support plates 5 to move away from each other. The lifting support plate 5 is tightly attached to the side wall of the inner ring of the metal pipe coil, and the metal pipe coil is fixed by friction. Then, the load cell 4 is raised under the drive of the palletizer, making the metal pipe coil suspended in the air. At this time, the fixed plate 2 and the detection end 41 of the load cell 4 are in close contact, and the position sensor 12 is triggered. The load cell 4 detects the weight at this time and records it as the load weight. The actual weight of the metal pipe coil is obtained by subtracting the empty weight from the load weight. Then, the palletizer moves the metal pipe coil to the unloading position. The palletizer drives the metal pipe coil to descend until it contacts the ground or other metal pipe coils on the ground. Meanwhile, the load cell 4 continues to descend under the drive of the palletizer until the position sensor 12 is in a non-triggered state. Then, the cylinder 3 drives the cylinder rod 31 to move downward, and the movable connecting rod 7 gradually retracts from the extended state, causing the lifting support plates 5 to move closer to each other and away from the side wall of the inner ring of the metal pipe coil. The metal pipe coil separates, thus realizing the function of weighing the metal pipe coil during the hoisting process.

[0032] Using the weighable automatic lifting device for metal pipe coils in this embodiment has the advantage of being able to weigh the metal pipe coils during the lifting process.
