Description

TECHNICAL FIELD

[0001] The utility model relates to a chemical fertilizer production equipment technical field especially, relates to a kind of turnover mechanism and for the turnover system of chemical fertilizer production. BACKGROUND

[0002] When compound fertilizer is produced, the compound fertilizer particles need to be loaded into packaging bags for sewing seam packaging. After sewing seam, the bagged chemical fertilizer on the conveyor moves downstream. Here, the bagged chemical fertilizer on the conveyor is in an upright state. During the conveying process, the bagged chemical fertilizer in the upright state needs to be adjusted to a flat state. Therefore, a mechanism for turning over the bagged chemical fertilizer is needed.

[0003] Currently, for the turnover of bagged chemical fertilizer, a turning-over conveying mechanism for bagged chemical fertilizer disclosed in CN204568762U is usually used. This mechanism can push down the chemical fertilizer bag standing on the conveyor belt and turn the bag body, so that the bag body finally lies flat along the direction of the conveyor belt, facilitating the use of a mechanical hand for stacking in the subsequent process. However, this mechanism has the following disadvantages: first, when the production line is running at a high speed, the bagged chemical fertilizer is prone to be jammed at the mechanism; second, after the bagged chemical fertilizer moves downstream, the mechanical hand can only grasp one bag of chemical fertilizer at a time for stacking. When the production line is running at a high speed, the downstream is prone to be congested. Therefore, the speed of the production line needs to be reduced, which affects the production efficiency. SUMMARY

A hinge ear seat is installed on the left side of the conveying frame. In the use state, one end of the telescopic mechanism is hingedly limited, and the other end is pivotally connected to the hinge ear seat to drive the conveying frame and the fork to overturn.

[0006] It also includes a third conveyor. The fixed hinge seat is fixedly installed on one side of the third conveyor. The two forks are located at the upstream end and the downstream end of the third conveyor, respectively.

[0028] Telescopic mechanism 50, robotic arm 60, photoelectric switch 70, bagged fertilizer 80. Detailed Implementation

[0029] Example 1:

[0030] like Figures 1-6 As shown, a material turning mechanism includes a turning frame 40 and a telescopic mechanism 50. The turning frame 40 includes a conveyor frame 41, a fork 42, and a fixed hinge seat 43. At least two forks 42 are fixedly installed on the lower side of the conveyor frame 41, and the forks 42 extend to the right side of the conveyor frame 41. The forks 42 are provided with a hinge hole 421 at one end near the conveyor frame 41. The forks 42 are pivotally connected to the fixed hinge seat 43 through the hinge hole 421. A hinge ear seat 414 is installed on the left side of the conveyor frame 41. In use, one end of the telescopic mechanism 50 is hinged and limited, and the other end is pivotally connected to the hinge ear seat 414 to drive the conveyor frame 41 and the forks 42 to turn.

[0031] The telescopic mechanism 50 drives the flipping frame 40 to flip, thereby turning the bagged fertilizer 80 located on the fork 42 from a vertical position to a horizontal position. In use, this invention removes the bagged fertilizer 80 from the production line for flipping, avoiding production line blockage.

[0032] See Figure 2 The figure shows the bagged fertilizer 80 positioned vertically on the fork 42 of the tipping frame 40. At this time, the telescopic mechanism 50 is extended, and the conveyor frame 41 is vertical. Afterwards, the telescopic mechanism 50 switches from the extended state to the retracted state. (See attached diagram.) Figure 6 This flips the bagged fertilizer 80 from a vertical position to a horizontal position. At this time, the conveyor frame 41 is in a horizontal position, the fork 42 is in a vertical position, and the bagged fertilizer 80 is located on the conveyor frame 41.

[0033] Specifically, the conveyor frame 41 includes a swing frame 411 and a plurality of support members 412 installed within the swing frame 411. The plurality of support members 412 are installed at intervals along the vertical direction of the swing frame 411. The spaced-out support members 412 facilitate the gripper of the robot arm to grasp the bagged fertilizer 80 located on the conveyor frame 41.

[0034] See Figure 5 A support plate 413 is installed on the left side of the swing frame 411, and a hinge ear 414 is installed on the support plate 413.

[0035] The telescopic mechanism 50 is one of a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0036] Example 2:

[0037] Based on Example 1, see Figures 1-4 The material turning mechanism also includes a third conveyor 30, with a fixed hinge seat 43 fixedly installed on one side of the third conveyor 30, and two shift forks 42 located at the upstream and downstream ends of the third conveyor 30, respectively. This structure facilitates the conveying of bagged fertilizer 80 to the top of the shift forks 42.

[0038] Specifically, see Figure 2 When the shift fork 42 is in the horizontal position, the top of the shift fork 42 is lower than the conveying plane of the third conveyor 30. When the shift fork 42 is in the vertical position, see [reference needed]. Figure 6 The shift fork 42 is away from the conveying area of ​​the third conveyor 30, so as not to obstruct the downstream movement of the bagged fertilizer 80.

[0039] Example 3:

[0040] Based on Example 2, see Figures 1-46. A turning system for fertilizer production, comprising a plurality of first conveyors 10 for conveying bagged fertilizer 80, and a turning mechanism, a downstream end of the first conveyors 10, and a third conveyor 30 installed between two adjacent first conveyors 10.

[0041] Specifically, see Figure 1 Two first conveyors 10 are installed sequentially, with an installation space 11 between them. A third conveyor 30 is installed within the installation space 11. When the bagged fertilizer 80 enters the upstream third conveyor 30, it is positioned above the shift fork 42. At this point, the telescopic mechanism 50 quickly retracts, flipping the bagged fertilizer 80 from the third conveyor 30 onto the conveyor frame 41. The robotic arm can then grab the bagged fertilizer 80 from the conveyor frame 41. After grabbing, the telescopic mechanism 50 extends, and the flipping frame 40 resets.

[0042] The next bag of fertilizer 80 on the first conveyor 10 passes through the third conveyor 30 upstream, then through the first conveyor 10 downstream, and moves to the third conveyor 30 downstream. At this time, the telescopic mechanism 50 located downstream quickly retracts, flipping the bag of fertilizer 80 from the third conveyor 30 onto the conveyor frame 41. After the bag of fertilizer 80 is grabbed by the robotic arm, the telescopic mechanism 50 extends, and the flipping frame 40 resets.

[0043] This invention allows for the removal and repackaging of bagged fertilizer from the production line, preventing congestion and improving production efficiency.

[0044] Example 4:

[0045] Based on Example 3, the material turning system for fertilizer production also includes multiple second conveyors 20. The second conveyors 20 are perpendicular to the first conveyor 10 and aligned with the third conveyor 30. There is a gap between the second conveyors 20 and the third conveyor 30 for the turning frame 40 to turn. The first conveyor 10 and the third conveyor 30 are at the same height, and the second conveyor 20 is lower than the third conveyor 30. The support member 412 is a free roller.

[0046] Based on the above structure, see Figure 6 Since the height of the second conveyor 20 is lower than that of the third conveyor 30, the conveyor frame 41 can be tilted and docked with the second conveyor 20. Furthermore, the support member 412 on the conveyor frame 41 is a free roller. Therefore, after being flipped, the bagged fertilizer 80 located on the conveyor frame 41 can move to the second conveyor 20 under the action of gravity, and then be conveyed to the robot arm 60 through the second conveyor 20, thereby further improving production efficiency.

[0047] In this embodiment, the first conveyor 10, the second conveyor 20 and the third conveyor 30 are respectively a belt conveyor or a roller conveyor.

[0048] In this embodiment, see Figure 2 One end of the telescopic mechanism 50 is hinged to the ground via a double-ear hinge seat, and the other end is hinged to the hinge ear seat 414 via a fisheye connector. Alternatively, one end of the telescopic mechanism 50 can also be hinged to the second conveyor 20 via a double-ear hinge seat, and the other end can be hinged to the hinge ear seat 414 via a fisheye connector.

[0049] Example 5:

[0050] Based on Example 3 or Example 4, see Figure 1 , 2 4. A photoelectric switch 70 is installed on the side of the third conveyor 30 away from the tipping frame 40. The photoelectric switch 70 is used to detect the bagged fertilizer 80 on the third conveyor 30.

[0051] See Figure 1 When the first bag of fertilizer 80 is detected by the photoelectric switch 70 at the upstream third conveyor 30, the upstream telescopic mechanism 50 drives the tipping frame 40 to flip. (See above) Figure 6 The first bag of fertilizer 80 is moved to the upstream second conveyor 20. During this process, the second bag of fertilizer 80 passes through the upstream third conveyor 30 and moves to the downstream third conveyor 30. When the photoelectric switch 70 at the upstream third conveyor 30 detects that the second bag of fertilizer 80 has left the upstream third conveyor 30, taking advantage of the gap between the second and third bags of fertilizer 80, the upstream telescopic mechanism 50 quickly drives the tipping frame 40 to reset. When the second bag of fertilizer 80 is detected by the photoelectric switch 70 at the downstream third conveyor 30, the downstream telescopic mechanism 50 drives the tipping frame 40 to flip, moving the second bag of fertilizer 80 onto the downstream second conveyor 20.

[0052] In this embodiment, the photoelectric switch 70 is a diffuse reflection infrared photoelectric switch.

[0053] When the bagged fertilizer 80 is located in front of the diffuse reflection infrared photoelectric switch, the infrared light emitted by the diffuse reflection infrared photoelectric switch is reflected by the packaging bag. The diffuse reflection infrared photoelectric switch receives the reflected signal, thus giving the PLC a signal that the bagged fertilizer 80 is present. When the bagged fertilizer 80 moves downstream and there is no bagged fertilizer 80 in front of the diffuse reflection infrared photoelectric switch, the diffuse reflection infrared photoelectric switch does not receive the reflected signal, thus giving the PLC a signal that the bagged fertilizer 80 is absent.

[0054] The operation process or principle of this utility model is as follows:

[0055] SeeFigure 1 When the first bag of fertilizer 80 is detected by the photoelectric switch 70 at the upstream third conveyor 30, the upstream telescopic mechanism 50 drives the tipping frame 40 to flip. (See above) Figure 6 The first bag of fertilizer 80 is moved to the second conveyor 20 upstream. During this process, the second bag of fertilizer 80 passes through the third conveyor 30 upstream and moves to the third conveyor 30 downstream.

[0056] When the photoelectric switch 70 at the upstream third conveyor 30 detects that the second bag of fertilizer 80 has left the upstream third conveyor 30, the upstream telescopic mechanism 50 quickly drives the tipping frame 40 to reset, taking advantage of the gap between the second bag of fertilizer 80 and the third bag of fertilizer 80.

[0057] When the second bag of fertilizer 80 is detected by the photoelectric switch 70 at the downstream third conveyor 30, the downstream telescopic mechanism 50 drives the tipping frame 40 to flip, moving the second bag of fertilizer 80 onto the downstream second conveyor 20. After that, the downstream telescopic mechanism 50 quickly drives the tipping frame 40 to reset.

[0058] In other words, in this embodiment, the upstream turning rack 40 rotates at intervals, while the downstream turning rack 40 rotates when it detects the bagged fertilizer 80.
