The distance meter 5 is arranged at the front of the conveyor belt 1, and is used to measure the diameter of the steel barrel 3 conveyed on the conveyor belt 1. The flexible track change assembly 4 is arranged below the conveyor belt 1, and is used to adapt to the diameter of the steel barrel 3 measured by the distance meter 5, so that the steel barrel 3 moves forward along the center of the conveyor belt 1. The first single-position blocking cylinder 8, the second single-position blocking cylinder 9 and the steel barrel blocking and releasing assembly 2 are arranged at the rear of the conveyor belt 1, and are respectively used to block the first steel barrel, the second steel barrel and the remaining steel barrels located at the rear of the conveyor belt from being conveyed forward.

[0021] The steel barrel conveying system with flexible track change provided by the present invention comprises the above-mentioned steel barrel conveying device with flexible track change and an elevator, and the end of the conveyor belt 1 is connected to the elevator 7.

[0022] Specifically, the conveyor belt 1 is provided with a plurality of rotatable conveyor rollers 11 , with gaps between adjacent conveyor rollers 11 , and the conveyor rollers 11 are driven to roll by a servo motor to transport the steel drum 3 from the front end of the conveyor belt 1 to the end. Figure 2 The direction indicated by the middle shear head is the conveying direction of the conveyor belt 1, which is recorded as the X direction.

[0023] At least two sets of the flexible track-changing components 4 are provided, which are respectively located at the rear of the conveyor belt 1 and the rear of the rangefinder 5. If the conveyor belt 1 is long, it is necessary to appropriately add flexible track-changing components 4 according to the situation.

[0024] The flexible track-changing assembly 4 includes a motor 41 , a forward and reverse screw rod 42 , an adjustment plate 43 , a guide rail 44 , a base 45 , a fixed pulley 46 and a column 47 . The base 45 is fixed on the ground below the conveyor belt 1, and the motor 41 is installed on the base 45. A guide rail 44 and two bearing seats are provided on the base 45 along the Y direction, and at least two second sliders 50 are provided on each guide rail 44; the positive and negative screw rods 42 are sleeved in the bearing seats on the base 45, and the positive and negative screw rods 42 are connected to the output end of the motor 41, and the positive and negative screw rods 42 are provided with a positive screw rod seat 48 and a negative screw rod seat 49; two adjusting plates 43 are provided, which are respectively located on both sides below the conveyor belt, and the two adjusting plates 43 are fixed on different second sliders 50, and are respectively fixedly connected to the positive screw rod seat 48 and the negative screw rod seat 49; a column 47 is provided on the adjusting plate 43, and the column 47 passes upward through the gap of the conveyor roller 11, and the fixed pulley 46 is symmetrically arranged on both sides above the conveyor belt 1 and installed on the column 46, that is, the fixed pulleys 46 on both sides of the conveyor belt 1 are at an equal distance from the central axis of the conveyor belt 1. The Y-direction positions of the fixed pulleys 46 on both sides of each group of flexible track-changing components 4 remain the same. Two steel wire ropes 6 are provided, which are respectively wound on the fixed pulleys 46 in each group of flexible track-changing components 4 on both sides of the conveyor belt 1, so that the steel wire ropes 6 remain parallel to the axis of the conveyor belt 1, and the distances between the steel wire ropes 6 on both sides and the axis of the conveyor belt 1 remain equal.

[0025] The motors 41 in each group of flexible track change components 4 rotate synchronously, driving each positive and negative threaded rod 42 to rotate synchronously in the forward or reverse direction, so that each positive threaded rod seat 48 and negative threaded rod seat 49 drive each adjustment plate 43 on both sides to move closer or farther from each other synchronously, thereby synchronously adjusting the spacing of each fixed pulley 46 on both sides above the transmission belt 1, and finally making the spacing of the wire ropes 6 on both sides match the steel barrel diameter measured by the distance meter 5, thereby realizing flexible track change. The conveying device of the present invention can be applied to the conveying of small steel barrels with a diameter of 260-500 mm.

[0026] One end of the steel wire rope 6 is fixed on the ground, and a counterweight 10 is hung on the other end, which can ensure that the steel wire rope 6 is always taut and straight during the flexible track change process.

[0027] The flexible track changing assembly 4 enables the steel wire ropes 6 on both sides to move symmetrically and parallelly along the axis of the conveyor belt 1 , so that the steel barrel 3 is conveyed along the central axis of the conveyor belt 1 after being limited by the steel wire ropes 6 .

[0028] The steel drum blocking and releasing assembly 2 comprises a bracket 21, a first cylinder 22, a second cylinder 23, a mounting plate 24, a slide rail 25, a first gear rod 26, a connecting rod 28, a second gear rod 29, a roller 30 and a vertical gear rod 31. The bracket 21 is arranged on the conveyor belt 1, and the height of the bracket 21 is higher than the height of the steel drum 3. Slide rails 25 are arranged on both sides of the top of the bracket 21 along the X direction, and a first slider 27 is arranged on the slide rail 25. Both ends of the mounting plate 24 are fixed on the first slider 27. The second cylinder 23 is installed on the top of the bracket 21, and the piston rod of the second cylinder 23 is connected to the mounting plate 24. The first gear rod 26 and the second gear rod 29 are hinged below the mounting plate 24, and the two ends of the connecting rod 28 are hinged to the first gear rod 26 and the second gear rod 29 respectively. The first cylinder 22 is installed on the mounting plate 24, and the piston rod of the first cylinder 22 is hinged to the end of the first gear rod 26. Front ends of the first gear rod 26 and the second gear rod 29 are connected to a vertical gear rod 31 , and the roller 30 is disposed at the bottom of the vertical gear rod 31 .

[0029] The X-direction position of the first gear rod 26 and the second gear rod 29 can be adjusted by the second cylinder 23, so that the vertical gear rod 31 and the roller 30 are located between the second steel drum and the third steel drum at the rear of the conveyor belt. The front ends of the first gear rod 26 and the second gear rod 29 can be controlled by the first cylinder 22 to open to both sides of the conveyor belt or to close to the middle. When closing, the roller 30 can block the third steel drum from continuing to be transported forward. When opening, the third steel drum is released and the third steel drum is continuously transported forward.

[0030] The first single-position blocking cylinder 8 and the second single-position blocking cylinder 9 are fixed under the conveyor belt, and their telescopic rods can extend upward through the gap between the conveyor rollers 11. After extending, they can block the steel barrels on the conveyor belt from being transported forward, and after retracting, the blocked steel barrels can continue to be transported forward. The first single-position blocking cylinder 8 is installed near the end of the conveyor belt to block the first steel barrel at the end of the conveyor belt. The distance between the first single-position blocking cylinder 8 and the second single-position blocking cylinder 9 is greater than the diameter of the steel barrel. The second single-position blocking cylinder 9 is used to block the second steel barrel at the rear of the conveyor belt.

[0031] The working process of the present invention is as follows: 1. Conveyor belt 1 starts to run, and steel drums are loaded from the front end of the conveyor belt. When the first steel drum moves to the distance meter 5, conveyor belt 1 stops rotating, and the distance meter 5 detects the diameter of the steel drum and provides feedback. After receiving the feedback, each group of flexible track change components 4 operates at the same time, adjusting the spacing between the steel wire ropes 6 on both sides to adapt to the measured diameter of the steel drum. Then conveyor belt 1 continues to rotate, and the steel drum moves along the conveying center of the conveyor belt under the action of the steel wire rope 6.

[0032] 2. The second cylinder 23 adjusts the mounting plate 24 to a suitable position, and the first cylinder 22 controls the first lever 26 and the second lever 29 to open, the second single positioning blocking cylinder 9 remains retracted, and the first single positioning blocking cylinder 8 extends. When the first steel barrel is transported to the end of the conveyor belt, the first single positioning blocking cylinder 8 blocks it from entering the elevator 7; then the second single positioning blocking cylinder 9 extends to block the second steel barrel from continuing to be transported forward. Then the first cylinder 22 controls the first lever 26 and the second lever 29 to retract, blocking the third and subsequent steel barrels from continuing to be transported forward.

[0033] 3. After the steel barrels are in place, the elevator 7 receives a signal, and the first single positioning blocking cylinder 8 retracts, allowing the first steel barrel to move forward and enter the elevator, and the elevator transfers the steel barrels. Then the first single positioning blocking cylinder 8 extends, and the second single positioning blocking cylinder 9 retracts, so that the second steel barrel moves forward and is blocked by the first single positioning blocking cylinder 8; at the same time, the first gear lever 26 and the second gear lever 29 open, allowing the third steel barrel to pass through and then retract, continuing to block subsequent steel barrels; the second single positioning blocking cylinder 9 extends again after the second steel barrel passes, blocking the third steel barrel. This action cycle is repeated, and each time the elevator transfers a steel barrel, the remaining steel barrels on the conveyor belt move forward one position until all steel barrels are transferred.

[0034] The above is a further detailed description of the present invention in combination with a specific implementation method, and it cannot be determined that the specific implementation of the present invention is limited to this; for technical personnel in the technical field to which the present invention belongs and related technical fields, based on the technical solution of the present invention, the expansion and replacement of operating methods and data should all fall within the protection scope of the present invention.
