Description

Technical Field

[0001] The utility model belongs to the technical field of ribbed steel bar production, and mainly relates to a multi-group chain platform conveying device for ribbed steel bar production. Background Art

[0002] In the production process of various steel bar products, steel bars of different lengths and diameters are used to meet the requirements of the production process. However, the workload of measuring and cutting steel bars is very large. When the existing equipment conveys steel bars, they are conveyed one by one separately, resulting in low efficiency.

[0003] Based on the above defects, the patent application document with the publication number CN112374094A discloses a conveying device and a steel bar production line. The conveying device includes a front-end conveying mechanism, a jacking and screening mechanism, and a sorting and conveying mechanism. The front-end conveying mechanism is used to convey multiple steel bar pieces. The jacking and screening mechanism is used to sort multiple steel bar pieces and jack the steel bar pieces to a preset height in sequence. The sorting and conveying mechanism is used to convey the steel bar pieces to the material taking area. Among them, the sorting and conveying mechanism includes a transmission component and a plurality of limiting structures connected to the transmission component. During the process of the transmission component conveying multiple steel bar pieces, adjacent two limiting structures can sort multiple steel bars and limit a single steel bar piece, so that the steel bar pieces are arranged at intervals on the transmission component, avoiding the occurrence of the situation of multiple steel bar pieces piling up. After the steel bar pieces are conveyed to the material taking area, it is convenient for the grasping mechanism to grasp them, improving the operation efficiency.

[0004] When the above-mentioned conveying device conveys steel bars, the arranged steel bars are prone to phenomena such as disorder and dislocation. Content of the Utility Model

[0005] The utility model provides a multi-group chain platform conveying device for ribbed steel bar production to solve the problem that multiple steel bars are prone to disorder and dislocation during conveying in the prior art.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] A multi-group chain platform conveying device for ribbed steel bar production includes a bracket and at least two chain conveying mechanisms arranged in sequence from front to back on the bracket. Among two adjacent chain conveying mechanisms in the front and back, at the end of the chain conveying mechanism located on the front side, a steel bar separating member and an end proximity switch are arranged in sequence along the front-back direction. The steel bar separating member is used to separate the steel bars into two batches in the front and back. On the chain conveying mechanism located on the rear side, a steel bar blocking member for blocking and aligning the steel bars is arranged. Both the steel bar blocking member and the steel bar separating member are movably assembled on the bracket along the up-down direction;

[0008] The steel bar separating member is used to rise when the steel bar touches the end proximity switch to separate the steel bar, and the steel bar separating member is used to descend after the chain conveying mechanism on the front side reverses and stops running;

[0009] The steel blocking member is used to descend after a first time interval when the steel separating member rises in place, and the steel blocking member is used to rise after a second time interval when all the steel bars between the steel separating member and the steel blocking member pass through the end proximity switch.

[0010] It has the following beneficial effects: When the steel bar contacts the end proximity switch, the steel separating member rises to separate multiple steel bars, so that some steel bars remain on the front side chain conveying mechanism and the other part remains on the rear side chain conveying mechanism. At the same moment after the steel separating member finishes rising, the front side chain conveying mechanism will move in the reverse direction, so as to better separate the two batches of steel bars. At the same time, after a short period of time, the steel blocking member will descend and no longer block the passage of the steel bars. Before the steel blocking member descends, the steel bar has already contacted the steel blocking member. Through the blocking of the steel blocking member, the steel bars are aligned, preventing the problem of disorder and misalignment that is likely to occur when multiple steel bars are conveyed.

[0011] Further, at least three chain conveying mechanisms are arranged on the bracket in sequence from front to back, namely a head end chain conveying mechanism, a tail end chain conveying mechanism, and at least one intermediate chain conveying mechanism located between the two. A storage full bin proximity switch is provided on the intermediate chain conveying mechanism, and the storage full bin proximity switch is located behind the steel blocking member on the same intermediate chain conveying mechanism.

[0012] It has the following beneficial effects: When the steel bar contacts the storage full bin proximity switch for a certain time, the front side chain conveying mechanism will stop moving until all the steel bars on the rear side chain conveying mechanism are conveyed away before it will restart.

[0013] Further, a front end proximity switch is also provided on the intermediate chain conveying mechanism, and the front end proximity switch is located between the end proximity switch and the steel blocking member.

[0014] It has the following beneficial effects: When the steel bar contacts the front end proximity switch, after a short delay, the steel blocking member will descend, thus allowing the steel bar to pass through. The time of this short delay is the time for the steel bar to be aligned.

[0015] Further, in two adjacent front and rear chain conveying mechanisms, the running speed of the rear side chain conveying mechanism is greater than that of the front side chain conveying mechanism.

[0016] Further, the rear side chain conveying mechanism and the front side chain conveying mechanism are arranged staggeredly in the left - right direction.

[0017] Further, a driving motor is provided on the bracket. Each chain conveying mechanism has multiple chains rotatably assembled on the bracket around an axis extending in the left - right direction, and one driving motor drives the multiple chains on the same chain conveying mechanism to rotate.

[0018] Further, two guide plates are provided on the bracket, and the two guide plates are disposed on the lower sides of the corresponding chains in the front-rear direction to support the chains.

[0019] It has the following beneficial effects: The guide plates are located below the chains, and the guide plates jack up the chains from the bottom to prevent the chains from coming into excessive contact with the bracket and affecting the movement of the chains.

[0020] Further, a limiting steel plate assembled on the bracket is provided at the front end of the head chain conveying mechanism, and the limiting steel plate is used to block the steel bars on the head chain conveying mechanism from falling. Description of the Drawings

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the following described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present utility model.

[0028] Various non-limiting embodiments of the present invention are described in detail below. Any number of elements in the accompanying drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0029] Example 1

[0030] like Figures 1 - 2 As shown, a multi-chain platform conveying device for producing ribbed steel bars includes a bracket 4, a first chain conveying mechanism 1, a second chain conveying mechanism 2 and a third chain conveying mechanism 3. The first chain conveying mechanism 1 is at the front side, the second chain conveying mechanism 2 is in the middle, and the third chain conveying mechanism 3 is at the rear side. The above three chain conveying mechanisms are all installed on the bracket 4 for conveying steel bars. In this embodiment, the bracket 4 can be 3, so that the first chain conveying mechanism 1, the second chain conveying mechanism 2 and the third chain conveying mechanism 3 are respectively installed on the corresponding bracket 4. In other embodiments, the bracket 4 can be 1 or 2 or more than 4. The steel bars in this embodiment are ribbed steel bars.

[0031] like Figure 1 , Figure 2 As shown, the first chain conveying mechanism 1, the second chain conveying mechanism 2 and the third chain conveying mechanism 3 each have a set of chains 6 and a driving motor 7 mounted on a bracket 4, and each set of chains 6 is rotatably mounted on the bracket 4 around an axis extending in the left-right direction. In this embodiment, each set of chains 6 is six chains parallel to each other in the left-right direction, and each chain 6 extends in the front-back direction, so that the chain 6 can transport steel bars in the front-back direction. The specific number of chains 6 can also be determined according to the actual length of the steel bars.

[0032] like Figure 3 As shown, the bracket 4 is provided with a rotating shaft 13 coaxially rotatably assembled around an axis extending in the left-right direction, the driving motor 7 is connected to the rotating shaft 13 so that the rotating shaft 13 can rotate, and the rotating shaft 13 is connected to all the chains 6. When the steel bar is transported, the axis of the steel bar and the chain 6 are perpendicular, and multiple chains 6 are arranged to facilitate the transportation of the steel bar.

[0033] like Figure 1 , Figure 2 As shown, two adjacent groups of chains 6 in the front-to-back direction are staggered in left-right arrangement, and the two groups of chains 6 have overlapping areas, that is, the rear end of the first chain conveying mechanism 1 and the front end of the second chain conveying mechanism 2 have overlapping areas, and the rear end of the second chain conveying mechanism 2 and the front end of the third chain conveying mechanism 3 have overlapping areas. The operating speeds of the first chain conveying mechanism 1, the second chain conveying mechanism 2 and the third chain conveying mechanism 3 increase in sequence.

[0034] A first steel separating member 5 is assembled at the end of the first chain conveying mechanism 1 described above. A first proximity switch 8, a second proximity switch 9, a first steel blocking member 11, and a full storage bin proximity switch 10 are sequentially and spacedly assembled on the second chain conveying mechanism 2 from front to back. The first steel separating member 5 is located on the front side of the first proximity switch 8. The first proximity switch 8, the second proximity switch 9, and the full storage bin proximity switch 10 are all installed on the bracket 4. The first steel separating member 5 and the first steel blocking member 11 are movably assembled on the bracket 4. A first steel separating driving member 19 and a first steel blocking driving member 20 are also respectively installed on the bracket 4. The first steel separating driving member 19 drives the first steel separating member 5 to move up and down on the bracket 4, and the first steel blocking driving member 20 drives the first steel blocking member 11 to move up and down on the bracket 4. The first steel separating driving member 19 in this embodiment is a hydraulic cylinder, and the first steel blocking driving member 20 is an air cylinder. In other embodiments, the first steel separating driving member 19 can be an air cylinder or an electric push rod, and the first steel blocking driving member 20 can be a hydraulic cylinder or an electric push rod.

[0035] The first steel separating member 5 jacks up upwards, thereby separating the steel bars into two parts. One part remains on the first chain conveying mechanism 1, and the other part remains on the second chain conveying mechanism 2, thereby separating multiple steel bars and preventing multiple steel bars from entering the second chain conveying mechanism 2 together, providing a basis for the subsequent alignment of the steel bars. After the first steel separating member 5 jacks up upwards and finishes, the driving motor 7 drives the first chain conveying mechanism 1 to reverse for a certain period of time and then stops running. When it stops running, the first steel separating member 5 descends and resets. The purpose of reversing is to prevent the steel bars from accumulating at the first steel separating member 5. When the steel bars are transported to just come into contact with the second proximity switch 9, after a certain period of time, the first steel blocking member 11 descends and no longer blocks the passage of the steel bars. Before the first steel blocking member 11 allows the steel bars to pass, the steel bars have already come into contact with the first steel blocking member 11. Through the blocking of the steel bars by the first steel blocking member 11, the alignment adjustment of the steel bars is realized.

[0036] A second steel separating member 16 is assembled at the end of the second chain conveying mechanism 2 described above. A third proximity switch 17 and a second steel blocking member 18 are sequentially and spacedly assembled on the third chain conveying mechanism 3 from front to back. The second steel separating member 16 is located on the front side of the third proximity switch 17. The structures of the first steel separating member 5 and the second steel separating member 16 in this embodiment are the same, and the structures of the first steel blocking member 11 and the second steel blocking member 18 are the same. The structures of the first proximity switch 8, the second proximity switch 9, the full storage bin proximity switch 10, and the third proximity switch 17 are the same. A second steel separating driving member 21 and a second steel blocking driving member 22 are also respectively installed on the bracket 4. The second steel separating driving member 21 drives the second steel separating member 16 to move up and down on the bracket 4, and the second steel blocking driving member 22 drives the second steel blocking member 18 to move up and down on the bracket 4. The second steel separating driving member 21 and the second steel blocking driving member 22 in this embodiment are both air cylinders. In other embodiments, the second steel separating driving member 21 and the second steel blocking driving member 22 can be hydraulic cylinders or electric push rods.

[0037] The second steel separating member 16 jacks upwards, thus separating the steel bars into two parts. After the second steel separating member 16 finishes jacking up, the driving motor 7 drives the second chain conveying mechanism 2 to reverse for a certain period of time and then stops running. When a certain period of time is set after the second steel separating member 16 finishes jacking up, the second steel blocking member 18 will descend and no longer block the passage of the steel bars, allowing the steel bars to pass through. Before the second steel blocking member 18 allows the steel bars to pass through, the steel bars have already contacted the second steel blocking member 18, and through the blocking of the second steel blocking member 18, the alignment adjustment of the steel bars is achieved.

[0038] The first steel separating member 5 has the same structure and working process as the second steel separating member 16. Through the above structure, the placement angle of the steel bars during conveying can be sorted out, thus preventing the problem of easy disorder and dislocation when multiple steel bars are conveyed.

[0039] A limiting steel plate 12 is provided at the front end of the first chain conveying mechanism 1. The limiting steel plate 12 is assembled on the bracket 4. The limiting steel plate 12 is used to block the steel bars on the first chain conveying mechanism 1 to prevent the steel bars from slipping off the first chain conveying mechanism 1.

[0040] The working process of the present utility model is as follows:

[0041] The staff places a bundle of steel bars on the first chain conveying mechanism 1. The driving motor 7 drives the first chain conveying mechanism 1 to run, and the steel bars are conveyed backward. When the steel bars touch the first proximity switch 8, the first chain conveying mechanism 1 stops running. The first steel separating driving member 19 drives the first steel separating member 5 to jack upwards to separate multiple steel bars. After the first steel separating member 5 finishes jacking up, the first chain conveying mechanism 1 runs in reverse for a set time and then stops. The reverse is to prevent the steel bars from piling up at the first steel separating member 5. The first steel separating member 5 descends and resets. The second chain conveying mechanism 2 starts to run to convey the steel bars. When the steel bars touch the second proximity switch 9, after setting a certain time, the first steel blocking member 11 descends. After multiple steel bars completely pass over the first steel blocking member 11, the first steel blocking member 11 rises and resets. The first chain conveying mechanism 1 will restart to run and continue to convey the steel bars, repeating the foregoing steps.

[0042] When there are enough steel bars on the second chain conveying mechanism 2, the steel bars will touch the storage full bin proximity switch 10. At this time, the first chain conveying mechanism 1 stops running and no longer conveys steel bars to the second chain conveying mechanism 2. The second chain conveying mechanism 2 continues to run to convey the steel bars.

[0043] When the steel bar touches the third proximity switch 17, the second chain conveyor mechanism 2 stops running, and the second steel bar separating drive 21 drives the second steel bar separator 16 to rise and jack up, separating the steel bars. After the second steel bar separator 16 finishes jacking up, the second chain conveyor mechanism 1 runs in reverse for a set time and then stops. The reverse running is to prevent the steel bars from piling up at the second steel bar separator 16. The second steel bar separator 16 descends and resets. The third chain conveyor mechanism 3 starts running to convey the steel bars. When the steel bar just touches the second proximity switch 9, after a certain time is set, the second steel bar stopper 18 descends to allow the steel bar to pass. After multiple steel bars completely leave the third proximity switch 17, after a certain delay, the second steel bar stopper 18 will rise and reset, and the second chain conveyor mechanism 2 will restart running to continue conveying the steel bars, repeating the above steps.

[0044] Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that there are more than two third chain conveyor mechanisms 3 in this embodiment, and the second steel bar separator, the third proximity switch, and the second steel bar stopper are also arranged on the third chain conveyor mechanism 3 in this embodiment. When there are multiple third chain conveyor mechanisms 3, except that the last third chain conveyor mechanism 3 does not have a storage bin full proximity switch 10, the other third chain conveyor mechanisms 3 need to be provided with a storage bin full proximity switch 10.

[0046] Based on the above description of this specification, those skilled in the art can also understand the following terms used. For example, terms indicating orientation or position relationship such as "upper", "lower", "front", "rear", "left", "right", "width", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or position relationship shown in the drawings of this specification. It is only for the purpose of facilitating the description of the solution of the present invention and simplifying the description, rather than explicitly or implicitly indicating that the device or element involved must have the specific orientation, be constructed and operated in the specific orientation. Therefore, the above orientation or position relationship terms cannot be understood or interpreted as a limitation to the solution of the present invention.

[0047] In addition, in the description of this specification, the meaning of "multiple" is at least two, such as two, three or more, etc., unless otherwise specifically defined.
