Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, and more particularly to a material turning device and a control method used on a roller conveyor line. Background Art

[0002] Bar flaw detection belongs to the process of assembly line automatic inspection, and its process is as follows: the bar is first shifted from the loading area to the conveyor roller line, and then shifted from the conveyor roller line to the unloading area after being inspected by the inspection assembly. The commonly used bar turning method generally adopts a tangible transition component to realize the turning by reciprocating and rotating motions. This method is mostly based on the principle of mechanical levers, using the connecting rod and transmission mechanism of a large force arm to grasp the bar through the swing of the rocker arm. Due to the use of lever connection and rocker arm swinging mode, the load torque of the driving source is increased, and the rapid and large movement of the lever or rocker arm will cause it to be shelved. The bars on the feeding device have a great impact on the material taking component, causing frequent equipment failures of the power driving source; in addition, during the material turning process, since the feeding device in the feeding area needs to feed the material at intervals, the unloading device in the unloading area also needs to send the inspected bars away in time to form a periodic material turning action. If multiple material turning devices are used to realize material turning, the working time of the material turning device must meet the non-working time of the material turning device, otherwise it will cause the bars to collide with the material turning mechanism and between the bars, thereby causing multiple bars to be disordered or even destructive collision accidents during the flaw detection operation. Therefore, it is necessary to propose a new material turning device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the drawings and are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0033] like Figure 1-3 As shown, the present invention proposes a material turning device for a roller conveyor line, comprising an introduction mechanism 1 and an export mechanism 2, wherein the introduction mechanism 1 is arranged between a loading platform 3 and a conveyor line 6, and the introduction mechanism 1 is located at the front end of a detection line assembly 4, and the export mechanism 2 is arranged between the conveyor line 6 and a unloading platform 5, and the export mechanism 2 is located at the rear end of the detection line assembly 4;

[0034] The import mechanism 1 and the export mechanism 2 both include a driving assembly and a plurality of flipping assemblies, the flipping assemblies include a support 10 and a rotating shaft 11, the two ends of the rotating shaft 11 are rotatably connected to the two supports 10, the plurality of rotating shafts 11 are parallel to each other, the rotating shaft 11 is perpendicular to the feeding direction of the conveyor line 6, and the rotating shaft 11 is connected to the driving assembly;

[0035] The introduction mechanism 1 further includes a plurality of first turning plates 8, along the length direction of the rotating shaft 11, the bottom edge of the first turning plate 8 is fixedly connected to the rotating shaft 11, one end of the first turning plate 8 is at the edge of the loading platform 3, and the other end of the first turning plate 8 is between the rollers of the conveyor line 6;

[0036] The output mechanism 2 also includes multiple second flipping plates 9. Along the length direction of the rotating shaft 11, the bottom edge of the second flipping plate 9 is fixedly connected to the rotating shaft 11, one end of the second flipping plate 9 is at the edge of the unloading platform 5, and the other end of the second flipping plate 9 is between the rollers of the conveyor line 6.

[0037] It is easy to understand that in the introduction mechanism 1, the number of the first turning plates 8 is the same as the number of the turning components. Similarly, in the take-out mechanism, the number of the second turning plates 9 is the same as the number of the turning components.

[0038] In the introduction mechanism 1, the function of the rotating shaft 11 is to rotate the first flipping plate 8. For example, the rotating shaft 11 puts the first flipping plate 8 in a flat state. At this time, the first flipping plate 8 is completely below the roller of the conveyor line 6 and does not contact the rod 7. When flipping is required, the rotating shaft 11 puts the first flipping plate 8 in a vertical state. At this time, the first flipping plate 8 lifts the rod 7, so that the rod 7 on the loading platform 3 rises and enters the top of the conveyor line 6 roller along the top edge of the first flipping plate 8. Then the first flipping plate 8 returns to a horizontal state again, and the rod 7 above the conveyor line 6 roller enters the conveyor line 6. Similarly, the movement process of the export mechanism 2 is similar to that of the introduction mechanism 1, and the rod 7 is guided from the conveyor line 6 to the unloading platform 5.

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

[0040] Bar material 7 introduction: multiple bars 7 to be tested are stored on the loading platform 3, and one end of the first turning plate 8 of the introduction mechanism 1 is below the edge of the loading platform 3. At this time, multiple first turning plates 8 are in a horizontal state and do not contact the bars 7;

[0041] The driving assembly drives the plurality of first turning plates 8 to rotate to a vertical state, lifts a bar 7 on the edge of the loading platform 3, separates the bar 7 from the loading platform 3, and rolls along the top edge of the first turning plates 8 into the conveyor line 6;

[0042] The plurality of first turning plates 8 are reset to a horizontal state, and the bars 7 on the loading platform 3 are rolled to the edge position, waiting to be introduced into the conveyor line 6;

[0043] Leading out the bar 7: After the bar 7 has been tested by the testing line assembly 4, it is transported to the side of the unloading platform 5 through the conveying line 6. At this time, the second turning plate 9 of the leading-out mechanism 2 is in a horizontal state and does not contact the bar 7;

[0044] The driving assembly drives the plurality of second turning plates 9 to rotate to a vertical state, lifts the bars 7 on the conveyor line 6, separates the bars 7 from the conveyor line 6, and rolls along the top edge of the second turning plates 9 into the unloading platform 5;

[0045] The plurality of second turning plates 9 are reset to a horizontal state, waiting for the next transfer of the bar 7 .

[0046] Furthermore, the top edge of the first flipping plate 8 is an inclined surface, the highest point of the top edge of the first flipping plate 8 is located in the loading platform 3, and the lowest point of the top edge of the first flipping plate 8 is located in the conveyor line 6. When the first flipping plate 8 rotates to a vertical state, the rods 7 on the loading platform 3 are lifted, and because the lifted rods 7 are in contact with only a plurality of first flipping plates 8, they will roll along the top plate of the first flipping plate 8 toward the conveyor line 6 under the action of gravity and enter the conveyor line 6.

[0047] Furthermore, a material stopper protrusion 13 is further provided on one side of the lowest point of the top edge of the first turning plate 8. When the first turning plate 8 is in a vertical state, the rod 7 rolls along the top edge of the first turning plate 8 and is finally stopped by the material stopper protrusion 13, so that the rod 7 is stably located above the conveyor line 6, and then the first turning plate 8 is reset to a horizontal state, so that the rod 7 descends and enters the conveyor line 6.

[0048] Furthermore, the top edge of the second flipping plate 9 is an inclined surface, the highest point of the second flipping plate 9 is located in the conveyor line 6, and the lowest point of the second flipping plate 9 is located in the unloading platform 5. When the second flipping plate 9 rotates to a vertical state, the rods 7 on the conveyor line 6 are lifted, and because the lifted rods 7 are in contact with only a plurality of second flipping plates 9, they will roll along the top plate of the second flipping plate 9 toward the unloading platform 5 under the action of gravity and leave the conveyor line 6.

[0049] Furthermore, a push protrusion 14 is provided on one side of the highest point of the top edge of the second turning plate 9. When the second turning plate 9 is in a vertical state, the bar 7 on the conveyor line 6 is lifted, and under the action of the push protrusion 14, the bar 7 rolls toward the lower material stand 5.

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

[0051] In the present invention, the drive assembly can be in various forms, such as a motor, a rotary drive cylinder, etc. Preferably, the present invention proposes a feasible drive assembly, which is as follows:

[0052] The driving assembly includes a bidirectional output shaft driving cylinder 15, a driving handle 12, a positioning frame 16, a cable sleeve 18 and a cable core 19. The positioning frames 16 are arranged in front and behind the bidirectional conveying shaft driving cylinder. In each flip assembly, one end of the rotating shaft 11 is fixedly connected to one end of the driving handle 12. The rotating shaft 11 and the driving handle 12 are arranged vertically, and the positioning frames 16 are arranged in front and behind each driving plate.

[0053] For each flipping assembly, a cable sleeve 18 is arranged between the positioning frame 16 in front of the driving plate and one of the positioning frames 16 outside the bidirectional conveying shaft driving cylinder, and a cable sleeve 18 is also arranged between the positioning frame 16 behind the driving plate and the other positioning frame 16 outside the bidirectional conveying shaft driving cylinder, and a cable core 19 is arranged in the cable sleeve 18, wherein one end of the cable core 19 is connected to the end of the driving 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 conveying shaft driving cylinder.

[0054] like Figure 3 As shown, the cable cores 19 are all driven by the bidirectional conveying shaft drive cylinder. Since the front and rear driving handles 12 of each flip assembly are connected by different cable cores 19, taking the flip assembly on the right side of the figure as an example, when the piston shaft 17 of the bidirectional conveying shaft drive cylinder extends to the right, the cable core 19 on the right side is in a loose state, and the cable core 19 on the left side is pulled, so that the first flip plate 8 or the second flip plate 9 rotates upward. When the piston shaft 17 of the bidirectional conveying shaft drive cylinder extends to the left, the cable core 19 on the left side is in a loose state, and the cable core 19 on the right side is pulled, so that the first flip plate 8 or the second flip plate 9 rotates downward. A drive assembly is respectively provided in the import mechanism 1 and the export mechanism 2. All the first flip plates 8 in the import mechanism 1 are driven by the drive assembly to achieve synchronous movement, and all the second flip plates 9 in the export mechanism 2 are driven by the drive assembly to achieve synchronous movement.

[0055] Furthermore, the driving assembly further includes a stopper 20, which is located outside the bidirectional conveying shaft driving cylinder and between one end of the piston shaft 17 and the positioning frame 16 on the same side, and the stopper 20 is provided with a through hole for the cable core 19 to pass through. The function of the stopper 20 is to limit the stroke of the piston rod of the bidirectional conveying shaft driving cylinder, thereby controlling the movement stroke of the cable core 19.

[0056] In the present invention, the bidirectional conveying shaft driving cylinder may be a bidirectional air cylinder or a hydraulic cylinder.

[0057] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
