Description

Technical Field

[0001] This invention relates to a double-code grouping device and method for steel profiles, belonging to the technical field of steel profile production equipment and methods. Background Technology

[0002] Section steel is mostly produced in multiples of length but delivered in fixed lengths. Traditional processes require straightening, grouping, and sawing the cooled, multiple-length steel during the rolling finishing process. Hot rolling of section steel requires heating, rolling, straightening, sawing, stacking, and packaging the steel billet for warehousing. The entire production process requires a large amount of energy and power. Most companies often pursue higher production efficiency to reduce production costs.

[0003] In terms of sawing efficiency, it is affected by factors such as the number of sawing equipment and the sawing operation rate. For existing production lines (especially continuous production lines with insufficient cold sawing capacity), it is difficult to effectively increase sawing capacity. When producing a wide variety of steel profiles (such as angle steel for iron towers with many different lengths), frequent length changes further affect sawing capacity and often lead to sawing process problems.

[0004] Therefore, how to improve sawing efficiency under the constraints of production plant and production line is a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to provide a steel section double-code grouping device and method. By using a double-code device to realize the double codes of steel sections, the steel sections with double codes are then grouped for cutting to length by sawing equipment. This improves the production efficiency of steel section cutting to length without increasing the sawing equipment, rationally arranges the sawing scheme, meets the rolling rhythm and capacity requirements, and requires no additional floor space, saving investment. It effectively solves the above-mentioned problems existing in the background technology.

[0006] The technical solution of the present invention is: a double-code grouping device for structural steel, comprising a double-code device, a grouping inlet roller conveyor, a grouping collection lifting chain, a grouping baffle one, a grouping baffle two, a grouping baffle three, a grouping outlet lifting chain, and a grouping outlet roller conveyor. The grouping inlet roller conveyor, the double-code device, the grouping collection lifting chain, the grouping baffle one, the grouping baffle two, the grouping baffle three, the grouping outlet lifting chain, and the grouping outlet roller conveyor are arranged sequentially along the structural steel process flow direction. The double-code device comprises a double-code frame, a lifting hydraulic cylinder, a lifting truss, and an electromagnetic crane. The lifting truss is arranged laterally on the double-code frame, the electromagnetic crane is connected below the lifting truss, and the lifting hydraulic cylinder is arranged between the top of the double-code frame and the lifting truss.

[0007] Sensors are installed on the grouping inlet roller conveyor and the double-code frame, and proximity switches are installed on the mechanical shaft of the grouping and collecting lifting chain and the lifting frame.

[0008] The distance between the second and third grouping baffles is not less than the effective width of the grouping exit roller conveyor.

[0009] It also includes an acquisition module, a judgment module, a first control module, and a second control module. The acquisition module, judgment module, first control module, and second control module are connected in sequence. The acquisition module and judgment module control the grouping inlet roller conveyor. The first control module controls the grouping baffle one, grouping baffle two, grouping material lifting chain, and double code device. The second control module controls the grouping baffle two, grouping baffle three, and grouping outlet lifting chain.

[0010] A method for grouping steel profiles using dual codes includes the following steps: (1) Obtain the current status of the inlet roller conveyor and determine whether there is structural steel on the roller conveyor; (2) If there is a section steel, determine whether the section steel on the current group entrance roller conveyor is the first section steel; (3) If so, the double-code grouping device will adsorb the first steel section and raise it to a certain height; (4) If the profile on the inlet roller conveyor of the current group is not the first profile, the double-code grouping device will place the first profile onto the second profile and perform double-code grouping. (5) Control the double-coded steel sections to be grouped and wait for sawing to length.

[0011] In step (3), the grouping and gathering lifting chain rises to the position and lifts the steel section stored on the grouping entrance roller conveyor. Once the grouping baffle is raised, the grouping and gathering lifting chain reverses and drives the steel section to the waiting position. The lifting hydraulic cylinder drives the lifting frame and electromagnetic crane to descend to the position. The electromagnetic crane is powered and magnetically adsorbs the steel section to rise to the designated position. The grouping and gathering lifting chain descends to the designated position.

[0012] In step (4), the grouping and collecting lifting chain rises to the position and lifts the steel section stored on the grouping entrance roller conveyor. Once the grouping baffle is raised, the grouping and collecting lifting chain reverses and drives the steel section to the waiting position. The lifting hydraulic cylinder drives the lifting frame and electromagnetic crane to descend to the position. The electromagnetic crane demagnetizes to realize double-layer steel section stacking. The lifting frame rises to the designated position.

[0013] The raising and lowering of the grouped material lifting chain to the designated position is determined and controlled by the proximity switch signal on the mechanical shaft of the grouped material lifting chain; the reverse rotation of the grouped material lifting chain to drive the steel section to the waiting position is controlled by the running time of the grouped material lifting chain drive motor; the raising and lowering of the lifting truss to the designated position is determined and controlled by the proximity switch signal of the lifting truss; the energizing and de-energizing of the electromagnetic crane is controlled by time.

[0014] During the dual-code process, the reverse running time of the grouped material collection chain is 1.7 seconds, the time for the electromagnetic crane to be energized and magnetized is 3 seconds, and the time for the electromagnetic crane to be de-energized and demagnetized is 2 seconds.

[0015] During the double-code process, when the grouping and collecting chain reverses, grouping baffle one and grouping baffle two rise up to prevent the steel sections stored on the grouping and collecting chain from entering the double-code area and the waiting-to-group area; after the steel sections are double-coded, when the grouping and collecting chain rotates forward, grouping baffle one descends and grouping baffle two rises, allowing the steel sections to enter the waiting-to-group area between grouping baffle one and grouping baffle two, and preventing the steel sections from entering the grouping area.

[0016] In step (5), the grouping outlet lifting chain rotates forward, the second grouping baffle descends, the third grouping baffle rises, the steel enters the grouping area between the second and third grouping baffles, and is counted by the counter. After the set number of groups is reached, the second grouping baffle rises, the third grouping baffle descends, the grouping outlet lifting chain rotates forward, and the steel enters the grouping outlet roller conveyor to wait for sawing to length.

[0017] The distance between the second and third grouping baffles shall not be less than the effective width of the grouping exit roller conveyor.

[0018] The beneficial effects of this invention are: by using a dual-code device to realize the dual-code of the steel profile, the steel profiles with dual codes are then grouped and cut to length by the sawing equipment. This improves the production efficiency of steel profile cutting to length without increasing the sawing equipment, rationally arranges the sawing scheme, meets the rolling rhythm and capacity requirements, and requires no additional floor space, thus saving investment.

Obviously, the embodiments described are only a small part of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0021] A double-code grouping device for structural steel includes a double-code device, a grouping inlet roller conveyor 7, a grouping and collecting lifting chain 8, a first grouping baffle 9, a second grouping baffle 10, a third grouping baffle 11, a grouping outlet lifting chain 12, and a grouping outlet roller conveyor 13. The grouping inlet roller conveyor 7, the double-code device, the grouping and collecting lifting chain 8, the first grouping baffle 9, the second grouping baffle 10, the third grouping baffle 11, the grouping outlet lifting chain 12, and the grouping outlet roller conveyor 13 are arranged sequentially along the structural steel process flow direction. The double-code device includes a double-code frame 1, a lifting hydraulic cylinder 2, a lifting truss 3, and an electromagnetic crane 4. The lifting truss 4 is arranged laterally on the double-code frame 1, the electromagnetic crane 4 is connected below the lifting truss 3, and the lifting hydraulic cylinder 2 is located between the top of the double-code frame 1 and the lifting truss 3.

[0022] Sensors are installed on the grouping inlet roller conveyor 7 and the double code frame 1, and proximity switches are installed on the mechanical shaft of the grouping material lifting chain 8 and the lifting frame 3.

[0023] The distance between the second grouping baffle 10 and the third grouping baffle 11 is not less than the effective width of the grouping exit roller conveyor 13.

[0024] It also includes an acquisition module 101, a judgment module 102, a first control module 103, and a second control module 104. The acquisition module 101, judgment module 102, first control module 103, and second control module 104 are connected in sequence. The acquisition module 101 and judgment module 102 control the grouping inlet roller conveyor 7. The first control module 103 controls the grouping baffle 1 9, the grouping baffle 2 10, the grouping collection lifting chain 8, and the double code device. The second control module 104 controls the grouping baffle 2 10, the grouping baffle 3 11, and the grouping outlet lifting chain 12.

[0025] A method for grouping steel profiles using dual codes includes the following steps: (1) Obtain the current status of the inlet roller conveyor and determine whether there is structural steel on the roller conveyor; (2) If there is a section steel, determine whether the section steel on the current group entrance roller conveyor is the first section steel; (3) If so, the double-code grouping device will adsorb the first steel section and raise it to a certain height; (4) If the profile on the inlet roller conveyor of the current group is not the first profile, the double-code grouping device will place the first profile onto the second profile and perform double-code grouping. (5) Control the double-coded steel sections to be grouped and wait for sawing to length.

[0026] In step (3), the grouping and gathering lifting chain rises to the position and lifts the steel section stored on the grouping entrance roller conveyor. Once the grouping baffle is raised, the grouping and gathering lifting chain reverses and drives the steel section to the waiting position. The lifting hydraulic cylinder drives the lifting frame and electromagnetic crane to descend to the position. The electromagnetic crane is powered and magnetically adsorbs the steel section to rise to the designated position. The grouping and gathering lifting chain descends to the designated position.

[0027] In step (4), the grouping and collecting lifting chain rises to the position and lifts the steel section stored on the grouping entrance roller conveyor. Once the grouping baffle is raised, the grouping and collecting lifting chain reverses and drives the steel section to the waiting position. The lifting hydraulic cylinder drives the lifting frame and electromagnetic crane to descend to the position. The electromagnetic crane demagnetizes to realize double-layer steel section stacking. The lifting frame rises to the designated position.

[0028] The raising and lowering of the grouped material lifting chain to the designated position is determined and controlled by the proximity switch signal on the mechanical shaft of the grouped material lifting chain; the reverse rotation of the grouped material lifting chain to drive the steel section to the waiting position is controlled by the running time of the grouped material lifting chain drive motor; the raising and lowering of the lifting truss to the designated position is determined and controlled by the proximity switch signal of the lifting truss; the energizing and de-energizing of the electromagnetic crane is controlled by time.

[0029] During the dual-code process, the reverse running time of the grouped material collection chain is 1.7 seconds, the time for the electromagnetic crane to be energized and magnetized is 3 seconds, and the time for the electromagnetic crane to be de-energized and demagnetized is 2 seconds.

[0030] During the double-code process, when the grouping and collecting chain reverses, grouping baffle one and grouping baffle two rise up to prevent the steel sections stored on the grouping and collecting chain from entering the double-code area and the waiting-to-group area; after the steel sections are double-coded, when the grouping and collecting chain rotates forward, grouping baffle one descends and grouping baffle two rises, allowing the steel sections to enter the waiting-to-group area between grouping baffle one and grouping baffle two, and preventing the steel sections from entering the grouping area.

[0031] In step (5), the grouping outlet lifting chain rotates forward, the second grouping baffle descends, the third grouping baffle rises, the steel enters the grouping area between the second and third grouping baffles, and is counted by the counter. After the set number of groups is reached, the second grouping baffle rises, the third grouping baffle descends, the grouping outlet lifting chain rotates forward, and the steel enters the grouping outlet roller conveyor to wait for sawing to length.

[0032] The distance between the second and third grouping baffles shall not be less than the effective width of the grouping exit roller conveyor.

[0033] An electronic device includes a processor and a memory, the memory being coupled to the processor and storing instructions that, when executed by the processor, perform the steps of any of the methods in the multi-type steel double-code grouping method.

[0034] A computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of any one of the methods in the multi-type steel double-code grouping method.

[0035] The embodiments of the present invention can realize the grouping and sawing of double or multiple layers of steel in the space height. The following description takes double layer stacking as an example.

[0036] In practical applications, the specific operation steps of the method of the present invention are as follows: (1) Obtain the signal that the grouping entrance roller conveyor is in a stopped state and obtain the signal that there is steel on the roller conveyor.

[0037] Specifically, the sensor at the marshalling yard entrance roller conveyor 7 confirms that the roller conveyor speed is zero, and the sensor next to the marshalling yard entrance roller conveyor 7 senses that there are structural steel sections stored on the roller conveyor.

[0038] (2) Determine whether the steel section on the inlet roller conveyor is the first steel section.

[0039] The judgment method is to use the sensor preset on the dual code frame of the dual code device to make the judgment. Specifically, if the predetermined position is detected to be a steel section, then the steel section on the grouping entrance roller conveyor 7 is not the first steel section; otherwise, if the predetermined position is not detected to be a steel section, then the steel section on the grouping entrance roller conveyor 7 is the first steel section 5.

[0040] (3) Control the dual-code device and the grouping device to implement the dual-code steps.

[0041] If it is the first section of steel, the grouping and gathering lifting chain rises, the grouping baffle rises, the grouping and gathering lifting chain reverses and drives the first section of steel 5 to the waiting position, the lifting hydraulic cylinder 2 in the double-code device drives the electromagnetic crane 4 to descend, the electromagnetic crane 4 is energized and magnetized, attracts the first section of steel and rises, the grouping and gathering lifting chain 8 descends.

[0042] If it is not the first section of steel, the grouping and collecting lifting chain 8 rises, the grouping baffle 9 rises, the grouping and collecting lifting chain 8 reverses to drive the second section of steel 6 to the waiting position, the lifting hydraulic cylinder 2 in the double-cash device drives the electromagnetic crane 3 to descend, the electromagnetic crane 3 is de-energized and demagnetized, the adsorbed first section of steel 5 is placed on the second section of steel 6 on the grouping entrance roller conveyor, the double-cash device rises, the grouping baffle 9 descends, and the grouping and collecting lifting chain 8 transfers the steel to the waiting grouping area.

[0043] During the double-code process, when the grouping aggregate lifting chain 8 reverses, the grouping baffle 1 9 and the grouping baffle 2 10 rise, preventing the steel sections stored on the grouping aggregate lifting chain 8 from entering the double-code area and the waiting-to-be-grouped area; after the steel sections are double-coded, when the grouping aggregate lifting chain 8 rotates forward, the grouping baffle 1 9 descends and the grouping baffle 2 10 rises, allowing the steel sections to enter the waiting-to-be-grouped area between the grouping baffle 1 9 and the grouping baffle 2 10, and preventing the steel sections from entering the grouping area.

[0044] Specifically, the raising and lowering of the grouped material lifting chain 8 to the designated position is controlled by the proximity switch signal on the mechanical shaft of the grouped material lifting chain 8; the reverse rotation of the grouped material lifting chain 8 to drive the steel section to the waiting position is controlled by the running time of the drive motor of the grouped material lifting chain 8; the raising and lowering of the double-code device to the designated position is controlled by the proximity switch signal of the lifting frame 3; the energizing and de-energizing of the electromagnetic crane 4 in the double-code device is controlled by time.

[0045] In one optional embodiment, the reverse running time of the grouped material lifting chain is 1.7 seconds, the time for the electromagnetic crane to be energized and attracted is 3 seconds, and the time for the electromagnetic crane to be de-energized and demagnetized is 2 seconds.

[0046] (4) The control grouping device groups the double-coded steel sections.

[0047] Specifically, the grouping outlet lifting chain 12 rotates forward, the grouping baffle 2 10 descends, and the grouping baffle 3 11 rises. The steel enters the grouping area between the grouping baffle 2 10 and the grouping baffle 3 11 and is counted by the counter. After the set number of groups is reached, the grouping baffle 2 10 rises, the grouping baffle 3 11 descends, the grouping outlet lifting chain 12 rotates forward, and the steel enters the grouping outlet roller conveyor to wait for transport and sawing to a fixed length.

[0048] Specifically, the lengths of the dual-code device and the grouping device are equal to the width of the cooling bed in the production line using this invention, which can meet the dual-code and grouping requirements of all long-length profiles.

[0049] After being rolled and straightened on the steel rolling production line, the steel billet is cut into fixed lengths by sawing equipment, completing the production process from billet to profile. This invention is applied between the straightening machine and the sawing equipment, improving the production efficiency of fixed-length sawing of steel profiles without adding sawing equipment, rationally arranging the sawing scheme to meet the rolling rhythm and capacity requirements, requiring no additional floor space, and saving investment.

[0050] The device of this invention includes, sequentially arranged along the steel section process flow direction, a grouping inlet roller conveyor 7, a double-code device, a grouping and collecting lifting chain 8, a grouping baffle 1 9, a grouping baffle 2 10, a grouping baffle 3 11, a grouping outlet lifting chain 12, and a grouping outlet roller conveyor 13.

[0053] During the double-code process, when the grouping aggregate lifting chain reverses, grouping baffle one and grouping baffle two rise up to prevent the steel sections stored on the grouping aggregate lifting chain from entering the double-code area and the waiting-to-be-grouped area; after the steel sections are double-coded, when the grouping aggregate lifting chain rotates forward, grouping baffle one descends and grouping baffle two rises, allowing the steel sections to enter the waiting-to-be-grouped area between grouping baffle one and grouping baffle two, and preventing the steel sections from entering the grouping area.

[0054] The raising and lowering of the grouped material lifting chain to the designated position is controlled by the proximity switch signal on the mechanical shaft of the grouped material lifting chain; the reverse rotation of the grouped material lifting chain to drive the steel section to the waiting position is controlled by the running time of the drive motor of the grouped material lifting chain; the raising and lowering of the double-code device is controlled by the proximity switch signal of the double-code device; and the energizing and de-energizing of the electromagnetic crane is controlled by time.
