Description

Technical Field

[0001] The invention relates to the technical field of metallurgical equipment, and in particular to a bundle collecting device and a profile production line. Background Art

[0002] At present, small profile production lines are used to produce bars when there are insufficient orders, in order to improve the utilization rate of equipment, thereby helping to increase production capacity and profit margins. The existing stacking and collection of profiles usually adopts the disk stacking method, and its core component is a set of liftable pull-out receiving arms. The specific operation process is as follows: when the stacking is completed, the receiving arm descends to place the profile on the roller; the receiving arm then withdraws, rises and re-extends, and then returns to the initial receiving position. This process involves four consecutive actions, namely, descending, withdrawing, rising, and extending. Before completing these actions, new profiles cannot be collected. Due to the low output and slow pace of profile production, this type of collection device generally does not restrict the production capacity of profile production. Compared with profiles, the collection method of bars (round steel) is completely different. Bars are usually collected in bundles by dropping, and the output can generally reach 2 to 3 times that of profiles. In order to improve the production capacity of bars, the working efficiency of the collection device is required to be high. Specifically: After the collection device completes the collection of a bundle of bars, it must transfer the bundle of bars as soon as possible to free up the receiving position so as to start collecting the next bundle of bars. Therefore, the production rhythm of bars is relatively fast, which places higher requirements on the response speed and efficiency of the collection device. Existing small profile production lines face different production rhythms and technical requirements in realizing the multifunctional application of profile and bar production. The design of the profile collection device is not suitable for the high-production demand of bars, resulting in a significant decrease in the efficiency of bar collection, which makes it impossible to fully release the production capacity of the production line and affects the overall production efficiency of the bars. Therefore, how to improve the collection device to better adapt to the different production rhythms of profiles and bars has become a technical problem that needs to be solved urgently.

The transport mechanism 200 includes a first transport vehicle 210 and a second transport vehicle 220 which can be lifted and lowered on the frame 100, and the first transport vehicle 210 and the second transport vehicle 220 are arranged at intervals; the material receiving mechanism 300 includes a first material receiving mechanism which can be movably arranged on the first transport vehicle 210, and a second material receiving mechanism which can be movably arranged on the second transport vehicle 220; the linkage mechanism 400 is arranged on the frame 100 and connects the first transport vehicle 210 and the second transport vehicle 220, and the linkage mechanism 400 is used to make the first transport vehicle 210 and the second transport vehicle 220 move in opposite phases; the lifting drive mechanism 500 is used to drive the first transport vehicle 210 or the second transport vehicle 220 to lift and lower.

[0045] In general, when the bundle collection device is used, multiple bundle collection devices are arranged at intervals along a preset direction on the profile production line, and the first and second transport vehicles 210 and 220 that can be raised and lowered cooperate with the first material receiving mechanism and the second material receiving mechanism to ensure that the profiles can be stacked in an orderly and stable manner. In addition, for the high-yield collection requirements of bar materials, the bundle collection device uses the linkage mechanism 400 to make the first and second transport vehicles 210 and 220 move in opposite phases, and the lifting and lowering drive mechanism 500 is used to achieve the relative lifting of the two trolleys, so that the two trolleys serve as counterweights for each other, further improving the stability and response speed of the equipment, thereby achieving rapid bundle collection of bar materials and improving the production efficiency of bar materials.

[0046] In addition, the present invention adopts a single frame design, which significantly reduces the equipment footprint and reduces the space occupied by the factory building compared to the double-frame solution in the prior art. Since the bundle collection device can simultaneously meet the collection requirements of profiles and bars, the investment cost of the equipment is greatly reduced. The present invention realizes efficient shared collection of profiles and bars through the bundle collection device, meets the requirements of profile stacking while taking into account the needs of high-yield collection of bars, thereby significantly improving production efficiency, reducing investment and operating costs, and enhancing the flexibility and adaptability of the bundle collection device.

[0047] In an embodiment of the present invention, the bundle collecting device further comprises a lifting and limiting structure arranged on the frame 100, and the first transport vehicle 210 and the second transport vehicle 220 perform lifting and lowering movements along the lifting and limiting structure.

[0048] The lifting limit structure can ensure that the first transport vehicle 210 and the second transport vehicle 220 always move within a predetermined range during the lifting process, thereby avoiding the problem of deviation or shaking and improving the lifting stability of the first transport vehicle 210 and the second transport vehicle 220.

[0049] Specifically, Figure 2 In the illustrated embodiment, the lifting and limiting structure includes a first lifting slot 110 and a second lifting slot 120 arranged on the frame 100. The first lifting slot 110 and the second lifting slot 120 both extend in the height direction and penetrate the frame 100 in the horizontal direction. The first transport vehicle 210 can be lifted and lowered in the first lifting slot 110, and the second transport vehicle 220 can be lifted and lowered in the second lifting slot 120.

[0050] The first lifting slot 110 and the second lifting slot 120 provide a stable lifting movement path for the first transport vehicle 210 and the second transport vehicle 220, ensuring that they always move along a predetermined trajectory during the lifting process, avoiding problems such as deviation or shaking, and making the lifting movement of the first transport vehicle 210 and the second transport vehicle 220 smoother, reducing position errors, and improving operational accuracy.

[0051] Furthermore, the maximum and minimum lifting ranges of the first transport vehicle 210 and the second transport vehicle 220 are limited by the first lifting chute 110 and the second lifting chute 120, thereby effectively preventing the first transport vehicle 210 and the second transport vehicle 220 from exceeding a safety range.

[0052] Designers can adjust the specific shapes and structures of the first lifting slot 110 and the second lifting slot 120 according to usage requirements, and no specific restrictions are made here.

[0053] Preferably, the cross-sections of the first lifting chute 110 and the second lifting chute 120 are configured as rectangles. More preferably, the first lifting chute 110 and the second lifting chute 120 are arranged side by side at the same height.

[0054] In an embodiment of the present invention, the bale collecting device also includes a first guide structure arranged between the frame 100 and the first transport vehicle 210, the first guide structure including a first guide rail arranged on the frame 100, and a first guide wheel arranged on the first transport vehicle 210, and the first guide wheel is slidably arranged on the first guide rail; and / or, the bale collecting device also includes a second guide structure arranged between the frame 100 and the second transport vehicle 220, the second guide structure including a second guide rail arranged on the frame 100, and a second guide wheel arranged on the second transport vehicle 220, and the second guide wheel is slidably arranged on the second guide rail.

[0055] Preferably, the bundle collecting device further comprises a first guide structure disposed between the frame 100 and the first transport vehicle 210 , and a second guide structure disposed between the frame 100 and the second transport vehicle 220 .

[0056] The first guide rail and the first guide wheel cooperate to provide a stable guide function for the first transport vehicle 210, so that the first transport vehicle 210 always moves along a predetermined track during the lifting and moving process. In addition, the second guide rail and the second guide wheel cooperate to provide a stable guide function for the second transport vehicle 220, so that the second transport vehicle 220 always moves along a predetermined track during the lifting and moving process.

[0057] The designer can adjust the shape, structure and arrangement of the first guide rail and the first guide wheel, as well as the second guide rail and the second guide wheel according to the use requirements, and no specific restrictions are made here. Wherein, the first guide rail and the second guide rail are both extended in the height direction.

[0058] In a feasible embodiment, the first guide rail is arranged on the inner wall of the first lifting chute 110 along the height direction, and the first guide wheel is arranged on the first transport vehicle 210 and connected to the first guide rail. The second guide rail is arranged on the inner wall of the second lifting chute 120 along the height direction, and the second guide wheel is arranged on the second transport vehicle 220 and connected to the second guide rail.

[0059] In another feasible embodiment, the first guide rail is arranged on the frame 100 along the height direction and is disposed outside the first lifting chute 110, and the first guide wheel is arranged on the first transport vehicle 210 and is connected to the first guide rail. The second guide rail is arranged on the frame 100 along the height direction and is disposed outside the second lifting chute 120, and the second guide wheel is arranged on the second transport vehicle 220 and is connected to the second guide rail.

[0060] Furthermore, a plurality of first guide rails are provided, and correspondingly, a plurality of first guide wheels are also provided, so that the motion stability of the first transport vehicle 210 is improved by the cooperation of the plurality of first guide rails. Furthermore, a plurality of second guide rails are provided, and correspondingly, a plurality of second guide wheels are also provided, so that the motion stability of the second transport vehicle 220 is improved by the cooperation of the plurality of second guide rails.

[0061] By providing the first guide structure and the second guide structure, not only the operating stability of the bundle collection device is improved, the safety performance is enhanced, the bundle collection device is made more reliable and efficient, and the demand for common collection of steel sections and bars is met.

[0062] In an embodiment of the present invention, Figure 1 and Figure 3 In the illustrated embodiment, the first material receiving mechanism includes a first material receiving arm 310 movably disposed on the first transport vehicle 210, and a first transverse driving device 320 disposed on the first transport vehicle 210, the first transverse driving device 320 being connected to the first material receiving arm 310, and the first transverse driving device 320 being used to drive the first material receiving arm 310 to extend or retract into the first transport vehicle 210.

[0063] By movably arranging the first material receiving arm 310 on the first transport vehicle 210, the first transverse driving device 320 can accurately control the extension and retraction of the first material receiving arm 310, ensuring that the first material receiving arm 310 can work accurately in different positions, thereby improving the flexibility of use of the first material receiving arm 310, thereby better meeting the collection needs of profiles and bars.

[0064] When the first receiving arm 310 extends out of the first transport vehicle 210, the profiles or bars can be stacked on the first receiving arm 310. When the first receiving arm 310 is retracted into the first transport vehicle 210, the profiles or bars can be placed on the roller conveyor, and the retraction of the first receiving arm 310 into the first transport vehicle 210 can also avoid affecting the use of the second receiving mechanism.

[0065] In an embodiment of the present invention, the bundle collecting device further comprises a first transverse guide structure provided on the first transport vehicle 210, and the first material receiving arm 310 reciprocates along the first transverse guide structure.

[0066] By arranging the first transverse guide structure on the first transport vehicle 210, the first transverse guide structure provides a stable movement path for the first material receiving arm 310, ensuring that it always moves along a predetermined trajectory during the extension and retraction process, avoiding the problem of deviation or shaking.

[0067] Specifically, the first transverse guide structure includes a first transverse slide groove provided on the first transport vehicle 210, the first transverse slide groove extends in the horizontal direction and penetrates the first transport vehicle 210, and the first receiving arm 310 is slidably provided in the first transverse slide groove. The first transverse slide groove is perpendicular to the first lifting slide groove 110. Furthermore, the first transverse slide groove is perpendicular to the profile or bar.

[0068] Through the guiding effect of the first transverse sliding groove, the movement of the first material receiving arm 310 is made more precise, the movement error of the first material receiving arm 310 is reduced, and the operation accuracy is improved.

[0069] In an embodiment of the present invention, Figure 2 In the illustrated embodiment, a first transverse roller set 111 is disposed in the first transverse slide groove, and the first material receiving arm 310 is slidably disposed on the first transverse roller set 111 .

[0070] By setting the first transverse roller group 111 in the first transverse slide groove, the friction between the first material receiving arm 310 and the first transverse slide groove is reduced by using the first transverse roller group 111, so that the first material receiving arm 310 can slide more smoothly and reduce the risk of jamming.

[0071] Designers can adjust the specific structure and arrangement of the first transverse roller group 111 according to usage requirements, and no specific restrictions are made here.

[0072] For example, the first transverse roller group 111 includes a plurality of first transverse rollers arranged in the first transverse slide groove, and the plurality of first transverse rollers are arranged in two rows at intervals. In addition, the first material receiving arm 310 is formed by T-shaped steel or I-shaped steel, and the first material receiving arm 310 is placed between the two groups of first transverse rollers.

[0073] In an embodiment of the present invention, the first transverse driving device 320 includes a first transverse hydraulic cylinder disposed on the first transport vehicle 210, and the piston rod of the first transverse hydraulic cylinder is connected to the first material receiving arm 310. Preferably, the piston rod of the first transverse hydraulic cylinder is hinged to one end of the first material receiving arm 310.

[0074] Specifically, the first transverse hydraulic cylinder is arranged in the horizontal direction. The first transverse hydraulic cylinder can drive the first material receiving arm 310 to perform telescopic reciprocating motion.

[0075] In an embodiment of the present invention, Figure 1 and Figure 3In the illustrated embodiment, the second material receiving mechanism includes a second material receiving arm 330 movably disposed on the second transport vehicle 220, and a second transverse driving device 340 disposed on the second transport vehicle 220, the second transverse driving device 340 being connected to the second material receiving arm 330, and the second transverse driving device 340 being used to drive the second material receiving arm 330 to extend or retract into the second transport vehicle 220.

[0076] By movably arranging the second material receiving arm 330 on the second transport vehicle 220, the second transverse drive device 340 can accurately control the extension and retraction of the second material receiving arm 330, ensuring that the second material receiving arm 330 can work accurately at different positions and heights, thereby improving the flexibility of use of the second material receiving arm 330, thereby better meeting the collection needs of profiles and bars.

[0077] Furthermore, the second receiving arm 330 and the first receiving arm 310 perform alternating actions to ensure that the profiles or bars can be stacked in an orderly and stable manner.

[0078] When the second receiving arm 330 extends out of the second transport vehicle 220, the profiles or bars can be stacked on the second receiving arm 330. When the second receiving arm 330 is retracted into the second transport vehicle 220, the profiles or bars can be placed on the roller conveyor, and the retraction of the second receiving arm 330 into the second transport vehicle 220 can also avoid affecting the use of the first receiving mechanism.

[0079] The designer can adjust the specific shape and structure of the first receiving arm 310 and the second receiving arm 330 according to the use requirements, and no specific limitation is made here. Preferably, the first receiving arm 310 and the second receiving arm 330 have the same structure, so as to ensure the stability of alternating stacking.

[0080] In an embodiment of the present invention, the bundle collecting device further comprises a second transverse guide structure provided on the second transport vehicle 220, and the second material receiving arm 330 reciprocates along the second transverse guide structure.

[0081] By arranging a second transverse guide structure on the second transport vehicle 220, the second transverse guide structure provides a stable movement path for the second material receiving arm 330, ensuring that it always moves along a predetermined trajectory during the extension and retraction process, avoiding the problem of deviation or shaking.

[0082] Specifically, the second transverse guide structure includes a second transverse slide groove provided on the second transport vehicle 220, the second transverse slide groove extends in the horizontal direction and passes through the second transport vehicle 220, and the second receiving arm 330 is slidably provided in the second transverse slide groove. The second transverse slide groove is perpendicular to the second lifting slide groove 120 and parallel to the first transverse slide groove.

[0083] Through the guiding effect of the second transverse sliding groove, the movement of the second material receiving arm 330 is made more precise, the movement error of the second material receiving arm 330 is reduced, and the operation accuracy is improved.

[0084] In an embodiment of the present invention, Figure 2 In the illustrated embodiment, a second transverse roller set 121 is disposed in the second transverse slide groove, and the second material receiving arm 330 is slidably disposed on the second transverse roller set 121 .

[0085] By setting the second transverse roller group 121 in the second transverse slide groove, the friction between the second material receiving arm 330 and the second transverse slide groove is reduced by using the second transverse roller group 121, so that the second material receiving arm 330 can slide more smoothly and reduce the risk of jamming.

[0086] Designers can adjust the specific structure and arrangement of the second transverse roller group 121 according to usage requirements, and no specific restrictions are made here.

[0087] For example, the second transverse roller group 121 includes a plurality of second transverse rollers arranged in the second transverse slide groove, and the plurality of second transverse rollers are arranged in two rows at intervals. In addition, the second material receiving arm 330 is formed by T-shaped steel or I-shaped steel, and the second material receiving arm 330 is placed between the two groups of second transverse rollers.

[0088] In an embodiment of the present invention, the second transverse driving device 340 includes a second transverse hydraulic cylinder disposed on the second transport vehicle 220, and the piston rod of the second transverse hydraulic cylinder is connected to one end of the second material receiving arm 330. Preferably, the piston rod of the second transverse hydraulic cylinder is hinged to one end of the second material receiving arm 330.

[0089] Specifically, the second transverse hydraulic cylinder is arranged in the horizontal direction. The second transverse hydraulic cylinder can drive the second material receiving arm 330 to perform telescopic reciprocating motion.

[0090] In an embodiment of the present invention, Figure 2 and Figure 3 In the illustrated embodiment, the linkage mechanism 400 includes a rotating shaft 410 disposed on the frame 100, a sprocket 420 disposed on the rotating shaft 410, and a chain 430 driveably engaged with the sprocket 420, and the chain 430 connects the first transport vehicle 210 and the second transport vehicle 220 respectively.

[0091] Specifically, the setting direction of the rotating shaft 410 is parallel to the first transverse sliding groove or the second transverse sliding groove, the chain 430 is meshed and set on the sprocket 420, and the two ends of the chain 430 are respectively connected to the first transport vehicle 210 and the second transport vehicle 220.

[0092] The rotating shaft 410 is rotatably disposed on the frame 100 , or the sprocket 420 is rotatably disposed on the rotating shaft 410 , which is not specifically limited herein.

[0093] The sprocket 420 and the chain 430 cooperate to ensure that the first transport vehicle 210 and the second transport vehicle 220 can move synchronously in opposite directions, thereby avoiding the problem of material accumulation or equipment jamming caused by the asynchrony between the first transport vehicle 210 and the second transport vehicle 220. In addition, the chain drive has good impact resistance and can work normally under complex working conditions, such as high load, frequent start and stop, etc.

[0094] Furthermore, a plurality of sprockets 420 are arranged side by side, and a chain 430 is correspondingly arranged on each sprocket 420 , and each chain 430 is respectively connected to the first transport vehicle 210 and the second transport vehicle 220 .

[0095] The cooperation of the plurality of sprockets 420 and the chains 430 ensures that the first transport vehicle 210 and the second transport vehicle 220 can achieve synchronous movement at a plurality of points, thereby avoiding the slight asynchronism that may be caused by a single chain 430 .

[0096] Furthermore, since multiple chains 430 share the load, the force on each chain 430 is more evenly distributed, which reduces the risk of overloading a single chain 430 and improves the stability of the overall system.

[0097] In a feasible embodiment of the present invention, the lifting drive mechanism 500 includes a lifting hydraulic cylinder arranged on the frame 100, the piston rod of the lifting hydraulic cylinder is rotatably connected to the first transport vehicle 210 or the second transport vehicle 220, and a linear displacement sensor is provided on the lifting hydraulic cylinder.

[0098] The smooth lifting action provided by the lifting hydraulic cylinder reduces the friction and impact between mechanical parts and prolongs the service life of the equipment. In addition, the linear displacement sensor can monitor the position of the piston rod in real time, providing accurate stroke information to ensure that the lifting action of the transport vehicle is accurate.

[0099] In another feasible embodiment of the present invention, the lifting drive mechanism 500 includes a drive motor, which is drivably connected to the linkage mechanism 400, and the drive motor is used to drive the linkage mechanism 400 to drive the first transport vehicle 210 and the second transport vehicle 220 to lift and lower.

[0100] Specifically, the drive motor is drivably connected to the sprocket 420 of the linkage mechanism 400 through a transmission structure. The drive motor can be programmed to achieve precise speed and position control, ensuring that the sprocket 420 can rotate accurately, thereby precisely controlling the lifting stroke.

[0101] In addition, the drive motor has the ability to start and stop quickly, can respond to operating instructions quickly, and realize efficient lifting operations. According to actual needs, the output power of the motor can be adjusted to change the speed of the sprocket 420 to achieve different lifting speeds, thereby better adapting to different operating needs.

[0102] In the embodiment of the present invention, the operation flow of the bundle collection device includes the following steps: the first transport vehicle 210 is located at the initial material waiting position, at which time the first transport vehicle 210 is in a high position, and the first receiving arm 310 is in an extended position to receive the material; the second transport vehicle 220 is in a low position, and the second receiving arm 330 is retracted. Then, the bundle collection device is used to collect the profile stacking or the bar falling material.

[0103] When stacking the profiles, the palletizer stacks the profiles on the first receiving arm 310. Each time a layer of profiles is stacked, the first transport vehicle 210 descends one layer and the second transport vehicle 220 rises synchronously until the stacking is completed.

[0104] When the bars are stacked, the chain conveyor transports the bars and drops them onto the first receiving arm 310. While the bars are falling, the first transport vehicle 210 slowly descends and the second transport vehicle 220 rises synchronously until the collection is completed.

[0105] After the collection is completed, the first transport vehicle 210 descends to a low position, places the profiles or bars on the roller, and then the first receiving arm 310 retracts; the second transport vehicle 220 rises to a high position simultaneously, and the second receiving arm 330 extends while the first receiving arm 310 retracts, until the second transport vehicle 220 is in the waiting position. At this time, the second transport vehicle 220 is in a high position, and the second receiving arm 330 is in an extended position for receiving materials; the first transport vehicle 210 is in a low position, and the first receiving arm 310 is in a retracted position.

[0106] The above actions are repeated to realize alternate material collection. In addition to the material collection time, the time interval between two material collections only includes the two action times of the transport vehicle descending and the material collection arm extending. Compared with the four action times of the material collection arm descending, retracting, ascending, and extending of the ordinary steel collection device, the interval time is shortened by half, thereby improving the production rhythm of the bundle collection device, which in turn helps to improve production efficiency.

[0107] The bundling collection device of the present invention makes up for the drawbacks of the profile production line in producing bar products. The bundling collection device can meet the needs of profile stacking collection and the high output of bar collection.

[0108] For a newly built steel production line, the investment can be reduced by using the bundle collection device of the present invention. Moreover, for an existing production line, the output of the bar can be increased and the profit can be increased by modifying and utilizing the bundle collection device of the present invention.
