Description

Technical Field

[0001] The invention relates to a back-end collecting device, in particular to a back-end collecting device for a bar production line, and belongs to the technical field of bar production. Background Art

[0002] During the back-end collection process of the bar production line, after the bars are collected on the large cooling bed, they need to be transported to the cold shearing machine through the output roller, cut into the required length, and then flipped and flat-towed to the finishing cooling bed. After counting and picking of non-fixed lengths, they are packaged into finished products. In this process, the bars are easily overlapped during the flat-tow transportation. At the same time, after cold shearing, non-fixed lengths and fixed lengths are mixed together, which requires manual picking and counting, wasting time and requiring a lot of manpower, resulting in a decrease in efficiency. In addition, the error of manual counting is large, which will cause quality problems such as more or less bars.

[0028] In order to elaborate on the technical scheme adopted by the present invention to achieve the predetermined technical purpose, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only partial embodiments of the present invention, rather than all embodiments, and the technical means or technical features in the embodiments of the present invention can be replaced without paying creative work. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0029] like Figure 1As shown, a post-process collection device for a bar production line of the present invention comprises a large cooling bed 1, a cold shear alignment roller 2, a finishing cooling bed 3, a first steel moving device 4, a cold shear 5, a non-fixed-size rejection mechanism 6 and a second steel moving device 7. The large cooling bed 1 is arranged on the side of one end of the cold shear alignment roller 2, the first steel moving device 4 is arranged between the large cooling bed 1 and one end of the cold shear alignment roller 2 to transfer the bars on the large cooling bed 1 to the cold shear alignment roller 2, the cold shear 5 and the non-fixed-size rejection mechanism 6 are arranged on the cold shear alignment roller 2 in sequence, the finishing cooling bed 3 is arranged on the side of the non-fixed-size rejection mechanism 6, and the second steel moving device 7 is arranged between the finishing cooling bed 3 and the non-fixed-size rejection mechanism 6 to transfer the fixed-size bars on the non-fixed-size rejection mechanism 6 to the finishing cooling bed 3. The bars on the large cooling bed 1 are transferred to the cold shear alignment roller 2 through the first steel moving device 4, and then transmitted to the cold shear machine 5 along the cold shear alignment roller 2. The spacing of the cold shear machine 5 is set to 36m, which can adapt to the simultaneous production of 9m fixed length and 12m fixed length. After the shearing is completed, the bars enter the non-fixed length rejection mechanism 6 to select the non-fixed length in the bars. The non-fixed length is transported to the non-fixed length baffle 8 at the other end along the cold shear alignment roller 2 and collected. The remaining fixed length is transported to the finishing cooling bed 3 through the second steel moving device 7. In this embodiment, the non-fixed length rejection mechanism 6 is set with two specifications of 9m fixed length and 12m fixed length, and the finishing cooling beds 3 of the two specifications are respectively set on the side of the non-fixed length rejection mechanism 6 of the corresponding specifications.

[0030] like Figure 2As shown, the cold shear alignment roller 2 is composed of multiple rollers 9 arranged in parallel along the conveying direction, each roller 9 is provided with a circular groove matching the bar, each roller 9 is driven by an independent drive motor 10, and the drive motor 10 can control the cold shear alignment roller 2 to transmit in the forward or reverse direction. A bent steel rejection device is provided at one end of the cold shear alignment roller 2, and the bent steel rejection device includes a conveying panel 11, multiple partitions and a partition lifting cylinder. The conveying panel 11 is horizontally arranged and fixed on the two side frames of the cold shear alignment roller 2. The conveying panel 11 is located between two adjacent rollers 9 of the cold shear alignment roller 2. The conveying panel 11 is provided with multiple grooves 12 matching the partitions, and the position of the groove 12 corresponds to the groove interface on the roller of the cold shear alignment roller 2. The partition is arranged on the partition lifting cylinder and is driven by the partition lifting cylinder to rise and fall in the groove. When the bars on the large cooling bed 1 are transferred to the cold shear alignment roller 2 by the first steel moving device 4, the partition lifting cylinder drives the partition to slide upward so as to extend out of the groove 12, and the bars are transmitted between two adjacent partitions. Since the spacing between the two partitions matches the groove width of the roller shaft 9, when the bars are bent steel, their overall width is greater than the spacing between the two partitions, so that the bent steel is stuck between the partitions and cannot be transmitted. Only straight bars can pass through the bent steel removal device smoothly. After the straight steel passes, the remaining stuck bent steel is removed manually or by the steel moving device when the partition descends. The present invention realizes automatic removal of bent steel through an ingenious partition structure, and its structure is simple and the cost is low, but it is practical and has a good bent steel removal effect.

[0031] like Figure 3 and Figure 4As shown, the first steel moving device 4 includes a steel moving bracket 13, a slider 14, a chain device and a chain lifting mechanism. The steel moving bracket 13 is provided with an oblique tooth groove matching the rod. The steel moving bracket 13 is arranged in the horizontal direction and one end of the steel moving bracket 13 is fixed on the slider 14. The slider 14 is arranged on the chain device and is driven by the chain device to move back and forth in the horizontal direction. The chain device is driven by the chain lifting mechanism to rise and fall in the vertical direction. The chain device includes a driving sprocket 15, a driven sprocket 16 and a chain 17. The driving sprocket 15 is rotatably arranged at one end of the chain lifting mechanism and is driven by a driving motor. The driven sprocket 16 is rotatably arranged at the other end of the chain lifting mechanism. The chain 17 is arranged on the driving sprocket 15 and the driven sprocket 16. The slider 14 is fixed on the chain. The chain lifting mechanism includes a chain lifting bracket 18 and a plurality of chain lifting cylinders 19. The driving sprocket 15 and the driven sprocket 16 are both rotatably arranged on the chain lifting bracket 18. The plurality of chain lifting cylinders 19 are vertically arranged at the lower side of the chain lifting bracket 18 to drive the chain lifting bracket 18 to lift and lower in the vertical direction. The driving sprockets 15 of the plurality of first steel moving devices 4 share a rotating shaft, and the driven sprockets 16 share a rotating shaft. All the driving sprockets 15 are synchronously driven by a driving motor. When the first steel moving device 4 is in use, the slider 14 is initially located at the leftmost end of the chain 17 and at the lower side of the rods on the large cooling bed 1. At this time, the chain lifting cylinder 19 drives the chain lifting bracket 18 to lift upward, so that the steel moving bracket 13 lifts the rods on the large cooling bed 1 to take the material. The driving motor rotates forward to cause the slider 14 to drive the steel moving bracket 13 to move to the right to above the cold shear alignment roller 2. The chain lifting cylinder 19 drives the chain lifting bracket 18 to descend, so that the steel moving bracket 13 descends and places the plate on the cold shear alignment roller 2. The driving motor reverses to cause the steel moving bracket 13 to move to the left to the initial position to complete a steel moving.

[0032] like Figure 5 As shown, the non-fixed-length rejecting mechanism 6 comprises a first fixed-length baffle mechanism 20 and a second fixed-length baffle mechanism 21 which are sequentially arranged along the transmission direction of the cold shear alignment roller. The distance between the first fixed-length baffle mechanism 20 and the second fixed-length baffle mechanism 21 is a fixed-length length. In this embodiment, at least two sets of fixed-length baffle mechanisms are required to realize a fixed-length. Figure 5 There is also a third fixed-size baffle mechanism 22, so that the distance between the first fixed-size baffle mechanism 20 and the second fixed-size baffle mechanism 21 is 12m, which can realize the rejection of non-fixed-size of 12m fixed-size, and the distance between the second fixed-size baffle mechanism 21 and the third fixed-size baffle mechanism 22 is 9m, which can realize the rejection of non-fixed-size of 9m fixed-size.

[0033] like Figure 6 and Figure 7As shown, the first fixed-size baffle mechanism 20 and the second fixed-size baffle mechanism 21 respectively include a main bracket 23, a baffle frame 24, a baffle frame lifting cylinder 25, a plurality of independent baffles 26 and a plurality of independent baffle lifting cylinders 27. The plurality of independent baffles 26 are arranged in parallel in the baffle frame 24 along the horizontal direction. Each independent baffle 26 is driven to rise and fall in the vertical direction by an independent baffle lifting cylinder 27. The baffle frame 24 is driven to rise and fall in the vertical direction by the baffle frame lifting cylinder 25. The baffle frame lifting cylinder 25 is arranged on the main bracket 23. The first fixed-size baffle mechanism 20 is provided with a first photoelectric scanner, and the second fixed-size baffle mechanism 21 is provided with a second photoelectric scanner.

[0034] The independent baffle 26 is a strip baffle arranged in the vertical direction. The width of the independent baffle 26 matches the groove spacing of the cold shear alignment roller 2. A plurality of vertical slide grooves corresponding to the independent baffles 26 are opened in the baffle frame 24. The independent baffle 26 is slidably arranged in the vertical slide groove of the baffle frame 24. A semicircular groove 28 matching the groove of the cold shear alignment roller 2 is opened at the lower side of the baffle frame 24 corresponding to each position of the independent baffle 26. When the independent baffle 26 slides downward to the lowest position, the lower end of the independent baffle 26 blocks the semicircular groove 28 of the baffle frame 24, thereby preventing the fixed length from passing.

[0035] The first photoelectric scanner is fixed on the side of the main bracket 23 of the first fixed-length baffle mechanism 20 facing the second fixed-length baffle mechanism 21, and the second photoelectric scanner is fixed on the side of the main bracket 23 of the second fixed-length baffle mechanism 21 facing the first fixed-length baffle mechanism 20. The photoelectric scanner can be a plurality of photoelectric sensors distributed in the transverse direction corresponding to the grooves of the cold shear alignment roller 2, or a photoelectric sensor can be used to perform continuous scanning detection using a transverse driving mechanism such as a screw rod.

[0036] The rods are fed from the end of the cold shear alignment roller 2 on one side of the first fixed-size baffle mechanism 20. At this time, the baffle frame lifting cylinder 25 of the first fixed-size baffle mechanism 20 contracts to allow the rods to pass smoothly. The baffle frame lifting cylinder 25 of the second fixed-size baffle mechanism 21 descends to completely block the cold shear alignment roller 2. The rods are aligned on the side of the baffle frame 24 of the second fixed-size baffle mechanism 21. After the alignment, the baffle frame lifting cylinder 25 of the second fixed-size baffle mechanism 21 contracts to allow the rods to pass smoothly. Due to factors such as the jam in the transportation of the rods, the first alignment of the rods may not completely make the front ends of all the rods aligned. At this time, after the rods continue to be transported along the cold shear alignment roller 2 for a distance, the baffle frame lifting cylinder 25 of the first fixed-size baffle mechanism 20 descends, and the drive motor of the cold shear alignment roller 2 reverses to cause the rods to be transported in the opposite direction. The tail end of the bar is aligned for the second time on the side of the baffle frame of the first fixed-length baffle mechanism 20. At this time, the tail end of the bar is completely aligned, and the first photoelectric scanner and the second photoelectric scanner simultaneously detect the bar on the cold shear alignment roller 2. When the first photoelectric scanner and the second photoelectric scanner corresponding to each groove have signal feedback, it is determined that the rebar in the corresponding groove is of fixed length. When only one photoelectric scanner has signal feedback or both photoelectric scanners have no signal feedback, it is determined to be non-fixed length. At this time, the independent baffle 26 of the fixed-length corresponding groove is driven by the independent baffle lifting cylinder 27 to descend to block the fixed length, and then the baffle frame lifting cylinder 25 of the first fixed-length baffle mechanism 20 and the second fixed-length baffle mechanism 21 shrinks to remove the non-fixed length, and the remaining blocked fixed length is transferred to the finishing cooling bed 3 by the second steel moving device. The non-fixed-length rejecting mechanism of the present invention is achieved by arranging two groups of fixed-length baffle mechanisms on the cold shear alignment roller, and each group of fixed-length baffle mechanisms is provided with a separate independent baffle corresponding to each groove of the roller. After the two groups of baffle mechanisms perform an alignment operation on the threaded steel bars, a photoelectric scanner is used to detect and determine whether the threaded steel bars are of a fixed length. For the threaded steel bars of a fixed length, the independent baffles are lowered to block the threaded steel bars so that only the threaded steel bars of a non-fixed length can pass through, thereby realizing automatic rejection of the threaded steel bars of a non-fixed length. Compared with manual rejection of the threaded steel bars of a non-fixed length, the cost and error rate are greatly reduced, and the production efficiency is improved.

[0037] like Figure 8 As shown, the second steel moving device 7 includes a flat support device 29, a flat support device swing drive mechanism and a flat support device pulley support mechanism. One end of the flat support device 29 is set on the flat support device swing drive mechanism and driven by the flat support device swing drive mechanism to swing left and right. The other end of the flat support device 29 is slidably set on the upper side of the flat support device pulley support mechanism. A semicircular groove matching the bar is opened on the upper side of the flat support device 29. The upper side of the chain plate of the mobile steel chain of the finishing cooling bed 3 is provided with an arc groove matching the bar, and the distance between the chain plates is equal to the distance between the semicircular grooves on the flat support device. The flat support device and the threaded steel of the mobile steel chain are accurately positioned, which is convenient for flat support steel moving and further avoids the overlapping and crossing problem of threaded steel caused by secondary positioning.

[0038] like Fig. 9As shown, the flat support device 29 includes a flat support rod 30, a flat support bracket 31 and a support rib plate 32. The flat support bracket 31 is fixed to the upper side of the flat support rod 30 through the support rib plate 32. The upper side of the flat support bracket 31 is provided with a plurality of semicircular grooves matching the rod material. The threaded steel bar is not easy to slide in the semicircular grooves, which can reduce the threaded steel bar rolling between the grooves during the steel moving process of the flat support device 29, causing the threaded steel bar to overlap and cross. The two ends of the upper side surface of the flat support bracket 31 are also provided with an inwardly inclined guide structure 33. The guide structure 33 effectively limits the threaded steel bar in the semicircular groove to the upper side of the flat support bracket 31 to prevent the threaded steel bar from accidentally falling. The swing drive mechanism of the flat support device comprises a swing arm 34, a swing arm hinge seat 35, a swing drive hydraulic cylinder 36 and a swing hydraulic cylinder hinge seat 37. One end of the swing arm 34 is hinged on the swing arm hinge seat 35, and the other end of the swing arm 34 is hinged to one end of the flat support rod 30. One end of the piston rod end of the swing drive hydraulic cylinder 36 is hinged on the swing arm 34, and the cylinder body of the swing drive hydraulic cylinder 36 is hinged on the swing hydraulic cylinder hinge seat 37. The swing arm 34 is controlled to swing back and forth along the lower end hinge shaft by the telescopic control of the swing drive hydraulic cylinder 36, thereby driving the flat support rod 30 to swing back and forth in the horizontal direction. The pulley support mechanism of the flat support device comprises a pulley 38, a pulley bracket 39, a rotating shaft 40, a rotating shaft bracket 41, a rotating shaft swing arm 42, a supporting driving hydraulic cylinder 43 and a supporting hydraulic cylinder bracket 44. The pulley 38 is rotatably arranged at one end of the pulley bracket 39. The lower side of the flat support rod 30 is supported on the upper side of the pulley 38 and can slide left and right on the upper side of the pulley 38. The rotating shaft 40 is rotatably arranged on the rotating shaft bracket 41. The other end of the pulley bracket 39 is fixed on the rotating shaft 40. One end of the rotating shaft swing arm 42 is fixed on the rotating shaft 40. The other end of the rotating shaft swing arm 42 is hinged to one end of the supporting driving hydraulic cylinder 43. The other end of the supporting driving hydraulic cylinder 43 is hinged to the supporting hydraulic cylinder bracket 44. The rotating shaft swing arm 42 is controlled to swing back and forth by the telescopic control of the supporting hydraulic cylinder 44. Since the rotating shaft swing arm 42 and the pulley bracket 39 are fixed on the same rotating shaft 40, the pulley bracket 39 swings together with the rotating shaft swing arm 42, thereby driving the pulley 38 to rotate along the rotating shaft 40. The swing drive mechanism of the flat support device and the pulley support mechanism of the flat support device are driven synchronously, so that when the swing drive mechanism drives the flat support rod 30 to move back and forth in the horizontal direction, the pulley support mechanism of the flat support device drives the pulley 38 to rotate to dynamically support the lower side of the flat support rod 30, and the posture of the flat support rod 30 is adjusted to ensure stability during the driving process, thereby avoiding overlapping and crossing of threaded steel bars during steel moving. The present invention improves the small straight tooth groove structure on the flat support device into a semicircular groove, which can effectively avoid overlapping and crossing caused by threaded steel bars sliding in the groove. At the same time, an arc groove with the same spacing as the semicircular groove is also provided on the chain plate of the moving steel chain, so that the threaded steel bars of the flat support device and the moving steel chain are accurately positioned, which is convenient for flat support steel moving, and further avoids the overlapping and crossing problem of threaded steel bars caused by secondary positioning.The present invention drives the flat supporting device synchronously through the swing driving mechanism of the flat supporting device and the pulley supporting mechanism of the flat supporting device. The swing driving mechanism of the flat supporting device is hinged to the flat supporting device, and the pulley supporting mechanism of the flat supporting device only performs rolling support on the lower side of the flat supporting device. The driving structure is simpler and more stable, and the overlapping and crossing of the threaded steel bars during the steel moving process are avoided.
