Description

Technical Field

[0001] This utility model relates to steel production equipment, and more particularly to an automatic bar bundling and sorting device. Background Technology

[0002] Currently, the production process of rolled steel bars requires the bar stock to be sorted and bundled. There are two main methods: online bundling and offline bundling. Online bundling refers to the bundling process after the bars are produced. The bars are conveyed on a flat surface and need to be sorted before bundling, so that they are gathered into a near-circular shape to facilitate subsequent bundling. Currently, this work in steel mills is done manually. Since the bar length is generally 6-12 meters, for thinner bars (such as Φ10-Φ20 rebar), which are relatively light, manual handling is relatively easy. However, for thicker bars (such as Φ40-Φ50 round steel), which are heavy, manual handling is time-consuming and labor-intensive. When the production line is handling two tracks simultaneously, the manual material handling rhythm is difficult to match the conveyor speed, leading to further efficiency reduction and seriously affecting production.

[0003] Furthermore, manual material handling is ineffective, resulting in irregularly shaped bundles that cannot meet the requirements of subsequent baling machines, leading to inconsistent baling quality. This causes the baling force of each bundle of rebar to be inconsistent, resulting in loose baling and other problems that pose risks during product transportation and storage. Summary of the Invention

[0004] This utility model addresses the shortcomings of existing technologies by providing an automatic bar bundling and sorting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic bar bundling and sorting device, comprising a base plate installed between two conveyor lines, wherein a left slide and a right slide are symmetrically arranged on the base plate and can move in opposite directions, the two slides are connected to the base plate through a guide mechanism and driven to move by a drive mechanism; an arc portion for gathering bars is provided on the inner side of the top of the slide; a flip-up baffle arc plate is also hinged on the slide, the baffle arc plate is connected to a baffle cylinder provided on the slide through a linkage mechanism.

[0006] Furthermore, the guiding mechanism includes upright plates fixed on both sides of the base plate and a guide shaft arranged parallel between the upright plates, and the slide table is slidably fitted onto the guide shaft through a through hole.

[0007] Furthermore, the drive mechanism includes a horizontal hydraulic cylinder fixed to the base plate, and the piston rod of the horizontal hydraulic cylinder is connected to a support plate fixed to the outside of the slide table.

[0008] Furthermore, there are two horizontal hydraulic cylinders, which respectively drive the left and right slides; the piston rod axis of the horizontal hydraulic cylinder is parallel to the guide shaft axis; the support plate is provided with mounting holes, and the end of the piston rod is hinged to the corresponding mounting hole of the support plate through a connecting pin, so that the linear motion of the horizontal hydraulic cylinder is converted into the linear sliding of the slide along the guide shaft.

[0009] Furthermore, the piston rod of the material-stopping cylinder is connected to the groove of the material-stopping arc plate via a pin, forming the linkage mechanism.

[0010] Furthermore, the baffle plate is hinged to the slide table via a rotating shaft.

[0011] Furthermore, when the piston rod of the baffle cylinder extends, it drives the baffle arc plate to rotate inward by 15-45 degrees to complete the secondary gathering of the bar.

[0012] Furthermore, the left and right slides include an integrally formed block structure. The top of the block structure is provided with two arcuate portions extending toward the direction of the bar material passage. A notch for accommodating the material blocking mechanism is formed between the two arcuate portions. A support for installing the material blocking cylinder is provided at the bottom of the notch.

[0013] Furthermore, both arc sections are provided with chamfered portions, which are located at the feed end of the arc sections; the chamfered portions of the two arc sections of the left slide are symmetrically convex teeth, and the chamfered portions of the two arc sections of the right slide are symmetrically concave teeth; when the slides are closed, the convex teeth and concave teeth form an interlocking structure.

[0014] Furthermore, the bar passes sequentially between the arcs of the two slides and between the two baffle arc plates; when the horizontal hydraulic cylinder drives the two slides to move towards each other, the arcs initially gather the bar; when the baffle hydraulic cylinder drives the baffle arc plate to flip inward, the baffle arc plate further gathers the initially gathered bar, so that the bar forms a circular bundle structure suitable for bundling.

[0015] Compared with the prior art, this utility model has the following advantages.

[0016] This invention enables automatic material handling of bar stock before online bundling, ensuring the bar stock meets bundling requirements and improving bundling efficiency. Furthermore, by replacing the guide plates with different curvatures, it can accommodate bundling of various sizes. Attached Figure Description

Detailed Implementation

[0027] like Figure 1-8 As shown, the automatic bar bundling and sorting device includes a base plate 101 installed between two conveyor lines 2. A left slide 106 and a right slide 107 that can move in opposite directions are symmetrically arranged on the base plate 101. The two slides are connected to the base plate 101 through a guide mechanism and are driven to move by a drive mechanism. An arc portion 109 for gathering the bars 3 is provided on the inner side of the top of the slide. A flip-up baffle arc plate, namely a left baffle arc plate 108 and a right baffle arc plate 117, is also hinged on the slide. The baffle arc plates 108 / 117 are connected to the baffle cylinder 113 on the slide through a linkage mechanism.

[0028] Preferably, the guiding mechanism includes upright plates 102 fixed on both sides of the base plate 101, and guide shafts 104 parallel to each other between the upright plates 102. A slide table is slidably fitted onto the guide shaft 104 through through holes. There are two guide shafts 104, arranged parallel to each other between the two upright plates 102. A left slide table 106 and a right slide table 107 are slidably fitted onto the two guide shafts 104 through through holes, respectively.

[0029] Preferably, the driving mechanism includes a horizontal hydraulic cylinder 103 fixed on the base plate 101, and the piston rod of the horizontal hydraulic cylinder 103 is connected to a support plate 105 fixed on the outside of the slide table. There are two horizontal hydraulic cylinders 103, which respectively drive the left slide table 106 and the right slide table 107; the piston rod axis of the horizontal hydraulic cylinder 103 is parallel to the axis of the guide shaft 104; the support plate 105 is provided with mounting holes, and the end of the piston rod is hinged to the corresponding mounting hole of the support plate 105 through a connecting pin, so that the linear motion of the horizontal hydraulic cylinder 103 is converted into the linear sliding of the slide table along the guide shaft 104.

[0030] In addition, the piston rod of the baffle cylinder 113 is connected to the groove 114 of the baffle arc plate 108 / 117 via a pin 115, forming a linkage mechanism.

[0031] Preferably, the two baffle plates 108 / 117 are hinged to their respective slides via their respective pivots 111. Specifically, the left slide 106 and the right slide 107 have notches 116 in the middle, and supports 112 are fixed at the bottom of the notches 116. A baffle cylinder 113 is mounted on the support 112 to provide secondary gathering power. The piston rod of the baffle cylinder 113 is connected to the groove 114 of the baffle plates 108 / 117 via a pin 115 to form a linkage mechanism. The baffle plates 108 / 117 are hinged to the slides via pivots 111 to achieve a flipping action. When the piston rod of the baffle cylinder 113 extends, it drives the baffle plates 108 / 117 to flip inward by 15-45 degrees to complete the secondary gathering of the bar.

[0032] Preferably, the left slide 106 and the right slide 107 comprise an integrally formed block structure. The top of the block structure has two arcuate portions 109 extending toward the direction of the bar 3. A notch 116 for accommodating a material-stopping mechanism is formed between the two arcuate portions 109. A support 112 for mounting a material-stopping cylinder 113 is provided at the bottom of the notch 116. Furthermore, both arcuate portions 109 have chamfered portions 110 located at the feed end of the arcuate portion 109. The chamfered portions 110 of the two arcuate portions 109 of the left slide 106 are symmetrically convex, while the chamfered portions 110 of the two arcuate portions 109 of the right slide 107 are symmetrically concave. When the slides are closed, the convex and concave teeth form an interlocking structure 118, i.e., a convex-concave interlocking fit. This arrangement effectively prevents the bar 3 from leaking out from the slide joint, ensuring the integrity of the bar's gathering.

[0033] During operation, the bar 3 passes sequentially between the arcs 109 of the two slides and between the two baffles 108 / 117. When the horizontal cylinder 103 drives the two slides to move towards each other, the arcs 109 initially gather the bar 3. When the baffle cylinder 113 drives the baffles 108 / 117 to flip inward, the baffles 108 / 117 further gather the initially gathered bar 3, forming a circular bundle structure suitable for bundling.

[0034] In one possible embodiment, the material handling device is installed in the middle of the two conveyor lines. The specific installation position is determined according to the bundling position. The number of devices installed is also determined according to the number of bundling tracks. Generally, one material handling device is required for each bundling track, and each bundle of bars is at least bundled into two tracks.

[0035] Another possible embodiment of the feeding device includes a base plate with a vertical plate mounted on each side. Each vertical plate has two mounting holes on its side, and guide shafts are mounted in the corresponding holes on the two vertical plates. A total of two guide shafts are mounted on the vertical plates, arranged in parallel. Through holes are provided on the left and right slides for engaging with the two parallel guide shafts, allowing the slides to run on the guide shafts. The left and right slides are mirror images of each other.

[0036] Another possible embodiment is that a support plate is fixedly installed on the outer side of each slide, and a connection hole is provided on the support plate to connect with the extension rod of the horizontal oil cylinder; each slide is equipped with a horizontal oil cylinder for driving operation, and the cylinder body of the horizontal oil cylinder is installed on the base plate.

[0037] Another possible embodiment is that the inner side of the top of the slide table is provided with an arc, the curvature of which is determined by the diameter of the bundled bars to be bundled. A chamfer is provided at the front end of the arc to allow the left and right slide tables to insert into each other by a certain distance during the process of the left and right slide tables being brought together.

[0038] In another possible embodiment, a notch is provided in the middle of the slide table, and a support is installed at the bottom of the notch. A material-blocking cylinder is installed on the support. The extension shaft of the material-blocking cylinder corresponds to the hole provided in the groove of the material-blocking arc plate, and the extension shaft is connected to the material-blocking arc plate by a pin.

[0039] Introduction to the on-site working process and scene of the material handling unit:

[0040] 1. Steel bars rolled on the rolling production line or transported from the warehouse are conveyed to the bundling area via roller conveyors. The speed of the roller conveyor can be adjusted according to the rhythm of the production line to ensure that the bars can continuously and stably enter the subsequent processes. After the bars arrive at the sorting station, there are positioning baffles at the end of the conveyor line to straighten the messy bars into a neat and even arrangement.

[0041] 2. At this point, the automatic material handling device is activated. The horizontal hydraulic cylinder retracts, driving the respective slides to achieve mirror motion of the left and right slides. During this motion, the rods laid flat on the conveyor surface are gathered together by the arcs of the slides until the chamfered edges of the two slides interlock, at which point the slides stop moving. At this point, the flat rods have basically completed the initial gathering (bundling process).

[0042] 3. Start the material blocking cylinder. The material blocking cylinder drives the corresponding material blocking arc plate to rotate at a certain angle along the inner side of the arc on the rotating axis, so that the bar material can be gathered a second time (bundling process). At this time, the bundled bar material has basically formed a circular bundle structure.

[0043] 4. Next to the automatic material handling device is a baler. After the material handling device completes the material handling, the baler's strapping storage device contains strapping tape (commonly steel tape, plastic steel tape, etc.). When baling begins, a motor drives the feed rollers to pull the strapping tape out of the storage device. The strapping tape is then fed along a specific track to the baling position, completing the baling of the bars.

[0044] 5. After the bundling work is completed, the automatic material handling device starts the material blocking cylinder to retract the material blocking arc plate, and then the horizontal cylinder rod extends to push the respective driven slide table to the initial position, waiting for the next bundling work.

[0045] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
