Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying, more particularly, to a turnover device for a roller conveying line and a control method. BACKGROUND

[0002] The rod detection belongs to a pipeline automatic detection process, and its process is that the rod is firstly displaced from a feeding area to a conveying roller line, detected by a detection assembly, and then displaced from the conveying roller line to a discharging area. The common rod turnover mode is generally to use a shaped transition component to realize turnover by reciprocating action and rotation action. This mode is generally to use a large force arm connecting rod and a transmission mechanism to swing a rocker arm to grab the rod, which increases the driving source load torque by using the lever connection and rocker arm swing mode, and the fast and large amplitude action of the lever or rocker arm will cause a great impact force of the rod placed thereon on the material taking component, and frequent equipment failure of the power driving source. In addition, in the turnover process, the feeding device in the feeding area needs to feed intermittently, and the discharging device in the discharging area needs to timely send away the detected rod to form a periodic turnover action. If multiple turnover devices are used to realize turnover, the working time of the turnover device needs to meet the non-working time of the turnover device, otherwise, the rod and the turnover mechanism and the rod and the rod will collide, which will cause a destructive collision accident of multiple rods in the detection operation process.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] It is worth noting that the directional terms such as "up" and "down" used in this article are all relative to the perspective of the attached figures and are only for the purpose of description. They should not be interpreted as limitations on the technical solutions.

[0033] like Figs. 1-3 As shown, the present invention proposes a material turning device for a roller conveyor line, including an inlet mechanism 1 and an outlet mechanism 2. The inlet mechanism 1 is disposed between the loading platform 3 and the conveyor line 6, and the inlet mechanism 1 is located at the front end of the detection line assembly 4. The outlet mechanism 2 is disposed between the conveyor line 6 and the unloading platform 5, and the outlet mechanism 2 is located at the rear end of the detection line assembly 4.

[0034] Both the inlet mechanism 1 and the outlet mechanism 2 include a drive assembly and multiple flipping assemblies. Each flipping assembly includes a support 10 and a rotating shaft 11. The two ends of the rotating shaft 11 are rotatably connected to the two supports 10 respectively. The multiple rotating shafts 11 are parallel to each other. The rotating shaft 11 is perpendicular to the feeding direction of the conveyor line 6. The rotating shaft 11 is connected to the drive assembly.

[0035] The feeding mechanism 1 also includes a plurality of first flipping plates 8. Along the length direction of the rotating shaft 11, the bottom edge of the first flipping plate 8 is fixedly connected to the rotating shaft 11. One end of the first flipping plate 8 is located at the edge of the loading platform 3, and the other end of the first flipping plate 8 is located between the rollers of the conveyor line 6.

[0036] The export mechanism 2 further comprises a plurality of second material turning plates 9, the bottom edges of which are fixedly connected to the rotating shaft 11 along the length direction of the rotating shaft 11, one end of each of the second material turning plates 9 is located at the edge of the unloading rack 5, and the other end of each of the second material turning plates 9 is located between the rollers of the conveying line 6.

[0037] It is easy to understand that the number of the first material turning plates 8 in the import mechanism 1 is the same as the number of the turning assemblies, and the number of the second material turning plates 9 in the export mechanism is the same as the number of the turning assemblies.

[0038] In the import mechanism 1, the rotating shaft 11 is used to rotate the first material turning plates 8, for example, the rotating shaft 11 is used to make the first material turning plates 8 in a horizontal state, at this time, the first material turning plates 8 are entirely below the rollers of the conveying line 6 and do not contact the bars 7, when it is necessary to turn the material, the rotating shaft 11 is used to make the first material turning plates 8 in a vertical state, at this time, the first material turning plates 8 lift the bars 7, the bars 7 on the feeding rack 3 are lifted and enter the above of the rollers of the conveying line 6 along the top edges of the first material turning plates 8, then the first material turning plates 8 return to the horizontal state again, and the bars 7 in the above of the rollers of the conveying line 6 enter the conveying line 6. Similarly, the movement process of the export mechanism 2 is similar to that of the import mechanism 1, and the bars 7 are guided from the conveying line 6 to the unloading rack 5.

[0039] Based on the material turning device of the application, the application proposes a control method for the material turning device on the roller conveying line, as follows:

[0040] The bars 7 are imported: a plurality of bars 7 to be detected are stored on the feeding rack 3, one end of each of the first material turning plates 8 of the import mechanism 1 is below the edge of the feeding rack 3, at this time, the plurality of first material turning plates 8 are in a horizontal state and do not contact the bars 7;

[0041] The driving assembly drives the plurality of first material turning plates 8 to rotate to a vertical state, lifts one bar 7 at the edge of the feeding rack 3, separates the bar 7 from the feeding rack 3, and makes the bar 7 roll along the top edge of the first material turning plate 8 and enter the conveying line 6;

[0042] The plurality of first material turning plates 8 are reset to the horizontal state, the bars 7 on the feeding rack 3 roll to the edge position, and wait to be imported into the conveying line 6;

[0043] The bars 7 are exported: after the bars 7 complete detection through the detection line assembly 4, the bars 7 are transported to one side of the unloading rack 5 through the conveying line 6, at this time, the second material turning plates 9 of the export mechanism 2 are in a horizontal state and do not contact the bars 7;

[0044] The driving assembly drives the plurality of second material turning plates 9 to rotate to a vertical state, lifts the bars 7 on the conveying line 6, separates the bars 7 from the conveying line 6, and makes the bars 7 roll along the top edge of the second material turning plate 9 and enter the unloading rack 5;

[0045] The plurality of second material turning plates 9 are reset to the horizontal state, and wait for the next time to transfer the bars 7.

[0046] Further, the top edge of the first material turning plate 8 is an inclined surface, the highest point of the top edge of the first material turning plate 8 is located in the feeding rack 3, and the lowest point of the top edge of the first material turning plate 8 is located in the conveying line 6. When the first material turning plate 8 is rotated to the vertical state, the bars 7 on the feeding rack 3 are lifted, and since the lifted bars 7 are only in contact with the plurality of first material turning plates 8, the bars 7 will roll along the top plate of the first material turning plate 8 to the conveying line 6 under the action of gravity and enter the conveying line 6.

[0047] Further, the top edge of the first material turning plate 8 is an inclined surface, the highest point of the top edge of the first material turning plate 8 is located in the feeding rack 3, and the lowest point of the top edge of the first material turning plate 8 is located in the conveying line 6. When the first material turning plate 8 is rotated to the vertical state, the bars 7 on the feeding rack 3 are lifted, and since the lifted bars 7 are only in contact with the plurality of first material turning plates 8, the bars 7 will roll along the top plate of the first material turning plate 8 to the conveying line 6 under the action of gravity and enter the conveying line 6.

[0048] Further, the top edge of the second material turning plate 9 is an inclined surface, the highest point of the top edge of the second material turning plate 9 is located in the conveying line 6, and the lowest point of the top edge of the second material turning plate 9 is located in the discharging rack 5. When the second material turning plate 9 is rotated to the vertical state, the bars 7 on the conveying line 6 are lifted, and since the lifted bars 7 are only in contact with the plurality of second material turning plates 9, the bars 7 will roll along the top plate of the second material turning plate 9 to the discharging rack 5 under the action of gravity and leave the conveying line 6.

[0049] Further, the top edge of the first material turning plate 8 is an inclined surface, the highest point of the top edge of the first material turning plate 8 is located in the feeding rack 3, and the lowest point of the top edge of the first material turning plate 8 is located in the conveying line 6. When the first material turning plate 8 is rotated to the vertical state, the bars 7 on the feeding rack 3 are lifted, and since the lifted bars 7 are only in contact with the plurality of first material turning plates 8, the bars 7 will roll along the top plate of the first material turning plate 8 to the conveying line 6 under the action of gravity and enter the conveying line 6.

[0050] Further, the number of the first material turning plates 8 is two, and the number of the second material turning plates 9 is two.

[0051] In the present application, the form of the driving assembly can be various, such as a motor, a rotary driving cylinder, etc., and preferably, the present application proposes a feasible driving assembly, which is as follows:

[0052] The driving assembly comprises a bidirectional output shaft driving cylinder 15, a driving handle 12, a positioning rack 16, a cable sleeve 18 and a cable core 19, the bidirectional output shaft driving cylinder is provided with the positioning rack 16 at the front and the back, one end of the rotary shaft 11 is fixedly connected with one end of the driving handle 12, the rotary shaft 11 is vertically arranged with the driving handle 12, and the positioning rack 16 is arranged at the front and the back of each driving plate;

[0053] For each flipping assembly, a cable sleeve 18 is provided between the positioning frame 16 in front of the drive plate and one of the positioning frames 16 outside the bidirectional conveyor shaft drive cylinder, and a cable sleeve 18 is also provided between the positioning frame 16 behind the drive plate and the other positioning frame 16 outside the bidirectional conveyor shaft drive cylinder. A cable core 19 is provided inside the cable sleeve 18, wherein one end of the cable core 19 is connected to the end of the drive plate away from the rotating shaft 11, and the other end of the cable core 19 is connected to the end adjacent to the piston shaft 17 of the bidirectional conveyor shaft drive cylinder.

[0054] like Fig. 3 As shown, all the cable cores 19 are driven by the bidirectional conveyor shaft drive cylinder. Since the drive handle 12 of each flipping component is connected to different cable cores 19 at the front and back, taking the flipping component on the right in the figure as an example, when the piston shaft 17 of the bidirectional conveyor shaft drive cylinder extends to the right, the right cable core 19 is in a loose state, and the left cable core 19 is pulled, causing the first flipping plate 8 or the second flipping plate 9 to rotate upward. When the piston shaft 17 of the bidirectional conveyor shaft drive cylinder extends to the left, the left cable core 19 is in a loose state, and the right cable core 19 is pulled, causing the first flipping plate 8 or the second flipping plate 9 to rotate downward. A drive component is set in the inlet mechanism 1 and the outlet mechanism 2 respectively. All the first flipping plates 8 in the inlet mechanism 1 are driven by the drive component to achieve synchronous movement, and all the second flipping plates 9 in the outlet mechanism 2 are driven by the drive component to achieve synchronous movement.

[0055] Furthermore, the drive assembly also includes a limiting member 20, which is located outside the bidirectional conveyor shaft drive cylinder and between one end of the piston shaft 17 and the positioning frame 16 on the same side. The limiting member 20 is provided with a through hole to facilitate the passage of the cable core 19. The function of the limiting member 20 is to limit the stroke of the piston rod of the bidirectional conveyor shaft drive cylinder, thereby controlling the movement stroke of the cable core 19.

[0056] In this invention, the bidirectional conveyor shaft drive cylinder can be a bidirectional pneumatic cylinder or a hydraulic cylinder.

[0057] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
