Description

Technical Field

[0001] The utility model relates to the technical field of article classification, in particular to a mechanism for sorting articles by using a servo drive. Background Art

[0002] In the fields of manufacturing and logistics, lane separation mechanisms such as lane conveying mechanisms can achieve efficient lane conveying in an easy-to-control manner. These mechanisms include conveying areas, guide rods, cylinders, rolling wheels and other components. By controlling the exit direction of the guide track, the movement of objects between different conveying lanes can be achieved. In the intelligent manufacturing production line, the lane separation mechanism works in coordination with the control unit and the logic unit to determine the next path of the object based on the reasoning results of the process, thereby realizing intelligent material separation and lane separation operations. Taking the transportation of bottled water in buckets as an example, the buckets are of different sizes, and the lane separation mechanism replaces manual labor to achieve the classification of the buckets.

[0003] For example, the patent with authorization announcement number CN220484357U discloses an automatic lane dividing mechanism, in which a mounting frame is fixedly connected to one side of a connecting rod close to a conveying platform, and a conveying roller is movably connected to the inner cavity of the mounting frame to prevent the bottled water from shifting and collapsing when the conveyor belt drives the bottled water to move. In addition, by controlling the moving distance of the mounting frame, bottled water of different sizes can be limited and clamped, thereby further improving the practicality. However, there are still certain shortcomings.

[0004] When transporting buckets of different models, the above patent requires manual assistance to adjust the distance between the two mounting frames, and cannot be adjusted autonomously. The scope of application scenarios is small. The dividing plate can control the sliding direction of the bucket, but there are only two directions, which limits the number of specifications of buckets that the dividing mechanism can adapt to, reducing practicality. Utility Model Content

[0005] In response to the above problems, the present application provides a mechanism for separating objects by servo drive, which solves the problem that the above patent requires manual assistance to adjust the distance between the two mounting frames when transporting buckets of different models, and cannot adjust autonomously, and has a small range of applicable scenarios. The dividing plate can control the sliding direction of the bucket, but only in two directions, thus limiting the number of specifications of buckets that the dividing mechanism can adapt to, reducing practicality.

[0006] A mechanism for separating articles by servo drive comprises a conveyor belt, two limit plates are symmetrically mounted on the top of the conveyor belt, one end of the two limit plates expands outward in a trumpet shape, a sliding column is fixedly mounted on the side of the limit plates away from each other, an adjustment plate is slidably mounted on the outside of the sliding column, a yield spring is fixedly mounted between the adjustment plate and the limit plate, a displacement mechanism is mounted on the outside of the adjustment plate, a mounting shell is fixedly mounted on the outside of the limit plate, a pressure sensor is slidably mounted inside the mounting shell, and a reset spring is fixedly mounted between the pressure sensor and the inner side of the mounting shell.

[0007] Furthermore, the displacement mechanism includes a servo motor, the bottom of which is fixed to the ground by a support frame, the servo motor is electrically connected to the pressure sensor, a bidirectional screw is fixedly installed on the output end of the servo motor, two linkage rods are symmetrically threaded on the outer side of the bidirectional screw rod, and the top of the linkage rod is fixedly connected to the adjustment plate.

[0008] Furthermore, a limit rod is installed in the middle of the linkage rod through which the limit rod is slidably installed, and an end of the limit rod is fixedly installed on the outside of the conveyor belt.

[0009] Furthermore, a stopper is fixedly mounted on one end of the sliding column away from the limiting plate.

[0010] Furthermore, an inclined plate is fixedly installed at the end of the conveyor belt.

[0011] Furthermore, a guide plate is rotatably mounted on the top of the inclined plate, and a connecting rod is hinged between the guide plate and the adjusting plate.

[0012] The beneficial effects of the utility model are as follows:

[0013] (1) In the utility model, a mechanism for separating articles by servo drive is described. The conveyor belt drives the bucket to move. If the outer diameter of the bucket is larger than the distance between the two limit plates, the bucket squeezes the limit plates, and the stop spring is compressed, thereby reducing the possibility of the bucket and the limit plates getting stuck.

[0014] The pressure sensor controls the rotation of the servo motor according to the pressure value received, driving the bidirectional screw to rotate, and then driving the linkage rod, adjustment plate, and limit plate to move away from or closer to each other, so that the distance between the two limit plates is adapted to the water bucket, and no staff intervention is required. It is simple and convenient, and more suitable for digital production lines.

[0015] (2) The utility model discloses a mechanism for separating articles by servo drive. When the adjusting plate moves, the guide plate is driven to rotate by the connecting rod. The inclination angle of the guide plate changes, and the end thereof corresponds to a different subsequent production line. Buckets of different sizes are then moved to the corresponding production line. Furthermore, the mechanism can be coordinated with multiple production lines according to actual needs, and has a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0022] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides a mechanism for separating articles by servo drive, including a conveyor belt 1, two limit plates 2 are symmetrically installed on the top of the conveyor belt 1 to limit the displacement path of the bucket and prevent it from tipping over. One end of the two limit plates 2 is expanded outward in a trumpet shape to facilitate the bucket to enter between the two limit plates 2. A sliding column 4 is fixedly installed on the side of the limit plates 2 away from each other, and an adjusting plate 3 is installed on the outer side of the sliding column 4 for sliding through. A stopper 6 is fixedly installed on the end of the sliding column 4 away from the limit plate 2 to prevent the adjusting plate 3 from separating from the sliding column 4. A yield spring 5 is fixedly installed between the adjusting plate 3 and the limit plate 2 to drive the limit plate 2 to reset and prevent the limit plate 2 and the bucket from being stuck due to the squeezing of the bucket. A displacement mechanism is installed on the outer side of the adjusting plate 3 to adjust the distance between the two limit plates 2.

[0023] A mounting shell 7 is fixedly mounted on the outer side of the limit plate 2, a pressure sensor 9 is slidably mounted inside the mounting shell 7, and a reset spring 8 is fixedly mounted between the pressure sensor 9 and the inner side of the mounting shell 7 for driving the pressure sensor 9 to reset.

[0024] In this embodiment, the water bucket enters from the bell-shaped mouth of the limit plate 2 and is driven to move by the conveyor belt 1. If the outer diameter of the water bucket is larger than the distance between the two limit plates 2, the water bucket squeezes the limit plate 2, and the displacement spring 5 is compressed, thereby reducing the possibility of the water bucket and the limit plate 2 being stuck. The movement of the limit plate 2 drives the pressure sensor 9 to squeeze the adjustment plate 3, and the reset spring 8 is compressed. The pressure sensor 9 sends the pressure value to the data processor in the form of an electrical signal, and the data processor sends an electrical signal to the displacement mechanism. The displacement mechanism drives the adjustment plate 3 and the limit plate 2 to move away from each other, so that the distance between the two limit plates 2 is adapted to the water bucket, and no staff intervention is required. This is simple and convenient, and is more suitable for digital production lines.

[0025] The buckets are placed in batches. When the outer diameter of the bucket becomes smaller, the squeezing force of the bucket on the limit plates 2 on both sides is insufficient, and the squeezing force on the pressure sensor 9 is insufficient. The displacement mechanism drives the two limit plates 2 closer to each other until the squeezing force on the pressure sensor 9 reaches the set value.

[0026] Specifically, the displacement mechanism includes a servo motor 13, the bottom of the servo motor 13 is fixed to the ground through a support frame, the servo motor 13 is electrically connected to the pressure sensor 9, a bidirectional screw rod 12 is fixedly installed at the output end of the servo motor 13, and two linkage rods 10 are symmetrically threaded on the outer side of the bidirectional screw rod 12. The bidirectional screw rod 12 is used to convert the rotation of the servo motor 13 into the linear motion of the linkage rod 10, and the top of the linkage rod 10 is fixedly connected to the adjustment plate 3.

[0027] In this embodiment, the pressure sensor 9 sends the pressure value to the data processor in the form of an electrical signal, and the data processor sends the electrical signal to the servo motor 13. The servo motor 13 rotates, driving the bidirectional screw rod 12 to rotate, and then driving the linkage rod 10, the adjustment plate 3, and the limit plate 2 to move away from or closer to each other, so that the distance between the two limit plates 2 is adapted to the bucket.

[0028] Specifically, an inclined plate 14 is fixedly installed at the end of the conveyor belt 1, and the water bucket above it can slide down under its own gravity. A guide plate 15 is rotatably installed on the top of the inclined plate 14 to guide the sliding direction of the water bucket. A connecting rod 16 is hinged between the guide plate 15 and the adjustment plate 3.

[0029] In this embodiment, when the adjustment plate 3 moves, the guide plate 15 is driven to rotate through the connecting rod 16, the inclination angle of the guide plate 15 changes, and the subsequent production lines corresponding to its ends are different, so buckets of different sizes are moved to the corresponding production lines, and it can be coordinated with multiple production lines according to actual needs, and has a wider range of applications.

[0030] Specifically, a limit rod 11 is slidably installed in the middle of the linkage rod 10 to limit the movement trajectory of the linkage rod 10 so that the linkage rod 10 can only move horizontally and linearly. The end of the limit rod 11 is fixedly installed on the outside of the conveyor belt 1.

[0031] How it works:

[0032] like Figure 1 As shown, the spacing between the two limit plates 2 is the minimum value, and the end of the guide plate 15 away from the servo motor 13 is inclined toward the side away from the servo motor 13. The water bucket enters from the bell mouth of the limit plate 2 and is driven to move by the conveyor belt 1. If the outer diameter of the water bucket is greater than the spacing between the two limit plates 2, the water bucket squeezes the limit plate 2, and the displacement spring 5 is compressed, reducing the possibility of the water bucket and the limit plate 2 being stuck. The movement of the limit plate 2 drives the pressure sensor 9 to squeeze the adjustment plate 3, and the reset spring 8 is compressed. The pressure sensor 9 sends the pressure value to the data processor in the form of an electrical signal, and the data processor sends an electrical signal to the servo motor 13. The servo motor 13 rotates, driving the bidirectional screw 12 to rotate, and then driving the linkage rod 10, the adjustment plate 3, and the limit plate 2 to move away from each other, so that the spacing between the two limit plates 2 is adapted to the water bucket, and no staff intervention is required. It is simple and convenient, and more suitable for digital production lines.

[0033] When the adjusting plate 3 moves, the connecting rod 16 drives the guide plate 15 to rotate, the inclination angle of the guide plate 15 changes, and the subsequent production lines corresponding to the end thereof are different, so buckets of different sizes are moved to the corresponding production lines. Moreover, it can cooperate with multiple production lines according to actual needs, and has a wider range of applications.

[0034] The buckets are placed in batches. When the outer diameter of the bucket becomes smaller, the squeezing force of the bucket on the limit plates 2 on both sides is insufficient, and the squeezing force on the pressure sensor 9 is insufficient, so the servo motor 13 is controlled to rotate in the opposite direction, driving the two limit plates 2 to approach each other until the squeezing force on the pressure sensor 9 reaches the set value.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
