Description

Technical Field

[0001] The invention belongs to the technical field of material sorting, and in particular relates to an electromechanical automated material sorting device. Background Art

[0002] The high-speed wheel sorter is driven by servo for sorting. It is usually installed at the sorting entrance and has the advantages of quick response, smooth operation and low noise. It is suitable for conveying and sorting various boxes, cartons, parcels and clothing. It has a wide range of adaptability and can be used in automated logistics warehouses in industries such as express delivery, e-commerce, medicine, clothing and books.

[0003] However, the existing pendulum wheel sorting machine has the following problems in the sorting process:

[0004] 1. For large or important sorting transfer stations, the weight, volume and barcode of the objects are usually collected through the DWS system, and the relevant information is uploaded to the information system in real time. Finally, the transportation route of the goods is planned. The knowledge and operations involved are extensive and complex, which leads to increased maintenance costs and difficulties in the later stage. At the same time, considering that the operators in some small sorting points in remote areas generally have a low level of cultural education, the phenomenon of simplifying or omitting the sorting steps based on weight occurs. Due to uneven force between the collected objects, the objects are damaged to varying degrees;

[0005] 2. The balance wheel in the high-speed balance wheel sorter rotates at high speed during the sorting process. According to common knowledge, the greater the gravity of an object, the greater its inertia will be when it moves at high speed. Therefore, when heavy objects pass through the high-speed rotating balance wheel, they will deviate from the center of the transportation path due to the influence of inertia. The balance wheel will change the corresponding angle while rotating, further affecting the directional transportation of heavy objects, and causing damage to fragile objects after collision with the transportation pipeline.

[0043] The present invention has the following beneficial effects:

[0044] 1. The present invention drives the movable rod to move downward by the receiving ball after being subjected to force, and controls the movable rod to move downward to different positions by the weight of the transported object itself, and then the travel ball interacts with the guide groove during the downward movement, so that the adjustment column drives the dial to rotate a certain angle, and the rotation angle of the dial is controlled by the variable distance of the downward movement of the movable rod, that is, objects of different weights are transported to different sorting and collection positions in a direction through a simple mechanical structure and a sensing device, which simplifies the operation steps and difficulty to a certain extent, reduces the later maintenance cost, and at the same time avoids the phenomenon of different degrees of damage to objects of uneven weight after sorting, reduces the after-sales loss rate and bad reviews, and improves the user's shopping experience.

[0045] 2. The present invention drives the No. 1 rack to move downward through the movable rod moving downward, until the No. 1 rack which is not meshed with the gear in the initial state moves relative to the gear, and then the No. 2 rack which is meshed with the gear in the initial state drives the sliding block to move upward under the action of the gear, and then the lifting rod drives the gravity wheel to move upward under the guidance of the support plate, until the gravity wheel extends out of the key groove and is at the same height as the steering wheel, and the friction between the gravity wheel and the heavy object is increased through the serpentine groove on the surface of the gravity wheel, thereby reducing the position offset of the object with large inertia to a certain extent, and reducing its rotation speed through the gravity of the gravity wheel itself, thereby slowing down the transportation speed of the object to a certain extent, avoiding collision of the object with large inertia during transportation, and improving the integrity of the object.

[0046] 3. The present invention sorts objects of different weights by the coordinated cooperation between the annular sensor and the detection rod. At the same time, the friction between the objects with large inertia is increased by the gravity wheel and the serpentine groove thereon. That is, while completing the sorting of different weights, the objects of different weights are stably and directional transported to the designated collection location, thereby improving the integrity of the objects, strengthening the coordination and cooperation between the mechanisms, and enhancing the practicality of the product.

[0065] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used in this document are only for the purpose of explanation and do not represent the only implementation method.

[0066] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0067] Reference Figure 1 It can be seen that an electromechanical automated material sorting device comprises an I-shaped seat 1 with a hollow structure in the middle part, a load-bearing plate 11 symmetrically distributed is arranged between the opposite surfaces of the inner walls of the vertical sections on the left and right sides of the I-shaped seat 1, through holes 12 and key-shaped grooves 13 corresponding to the through holes 12 are evenly opened in the horizontal section above the I-shaped seat 1, a support unit 2 is arranged on the load-bearing plate 11, a control unit 3 is jointly arranged on the I-shaped seat 1 and the support unit 2, a friction unit 4 is arranged on the load-bearing plate 11, and a telescopic unit 5 that is expected to cooperate is arranged on one side of the friction unit 4;

[0068] Reference Figure 1 , Figure 2 and Figure 6 It can be seen that the support unit 2 includes: a telescopic support 21, which is symmetrically fixedly installed on the upper end surface of the load-bearing plate 11, and the telescopic end of the telescopic support 21 passes through the load-bearing plate 11; four strip plates 22, and the strip plates 22 at the front and rear ends are fixedly installed on the inner concave surface of the upper end of the telescopic support 21; six positioning blocks 23, three in a group, and each group is evenly distributed on the upper end surfaces of the strip plates 22 at the front and rear ends; a partition plate 24, which is fixedly installed on the upper end surfaces of the positioning blocks 23 opposite to each other on the front and rear sides by bolts, and the middle position of the upper end surfaces of all the partition plates 24 is commonly provided with two symmetrical strip plates 2 2; locating pins 25, the number of which is 12, four in a group, each group is evenly distributed on the partition plate 24 at the corresponding position, and the two locating pins 25 at the middle position of each group are detachably installed while penetrating the partition plate 24 and the strip plate 22; a connecting shaft 26 is installed through the middle position of each of the partition plates 24, and is located between the two locating pins 25 at the middle position of each group of locating pins 25; a key-shaped plate 27 is fixedly installed on the outer wall of each locating pin 25 at the front and rear ends and the lower end of the connecting shaft 26; a connecting rod 28 is rotatably installed on the key-shaped plate 27 away from the locating pin 25 or the connecting shaft 26 at one end of the corresponding position.

[0069] During specific operation, a stable force-bearing base point is provided for the telescopic support 21 through the symmetrically distributed load-bearing plates 11, so that the grid structure composed of the strip plates 22 and the partition plates 24 can move stably downward as a whole after being stressed, avoiding affecting the coordinated cooperation of the telescopic unit 5 and the friction unit 4. Moreover, the strip plates 22 and the partition plates 24 are stably installed in a detachable manner through the positioning pins 25, which is convenient for maintenance and inspection. At the same time, through the connecting shaft 26 and some of the positioning pins 25 (the positioning pins 25 distributed in a rectangle), corresponding adjustments are made for the belt arrangement and fastening in the control unit 3. Finally, through the cooperation between the key-shaped plate 27 and the connecting rod 28, the linkage between the support unit 2 and the telescopic unit 5 is ensured (to prevent the telescopic unit 5 from losing the着力点 and becoming disconnected from the support unit 2 and the control unit 3, thus affecting the complete presentation of the product function).

[0070] Referring to Figure 1 and Figure 2 As can be seen, the control unit 3 includes: three first rollers 31, which are rotatably installed through the vertical sections on the left and right sides of the I-shaped seat 1. The outer wall of each first roller 31 is evenly provided with three annular grooves 32; a driving motor 33, which is fixedly installed on the inner wall of the rear side of the vertical section at the right end of the I-shaped seat 1, and the motor shaft of the driving motor 33 penetrates through the vertical section at the right end of the I-shaped seat 1; belt pulleys 34, which are fixedly installed at both ends of each first roller 31 and the end of the motor shaft of the driving motor 33. The two belt pulleys 34 on the front end side close to the driving motor 33 are driven by a belt with each other. At the same time, the belt pulley 34 on the motor shaft of the driving motor 33 and the belt pulley 34 on the rear end side close to the driving motor 33 are driven by a belt with each other. The two belt pulleys 34 on the rear end side far from the driving motor 33 are driven by a belt with each other;

[0071] Referring to Figure 1 and Figure 3 As can be seen, there are two second rollers 35, which are symmetrically rotatably installed at both ends of the I-shaped seat 1 and are located above the first rollers 31; toothed belt pulleys 36, which are fixedly installed at the lower end positions of the outer walls of each connecting rod 28, as well as on the outer walls of the front and rear positioning pins 25 on the side far from the driving motor 33. Two toothed belt pulleys 36 are evenly installed on the outer wall of the connecting rod 28 at the middle position of the farthest end of the driving motor 33;

[0072] Referring to Figure 4 and Figure 5 As can be seen, a C-shaped plate 281 is fixedly installed through the outer wall of the upper end of the connecting rod 28. A steering wheel 282 is rotatably installed between the two vertical sections on both sides of the C-shaped plate 281. An opening groove 283 is provided at the middle position of the outer wall of the steering wheel 282. A driving belt 284 is provided between the opening groove 283 and the annular groove 32. Moreover, a serpentine groove 48 is also evenly provided on the outer wall of the steering wheel 282;

[0073] Referring to Figure 1 and Figure 4 It can be seen that the diameter of the steering wheel 282 is equal to its length. At the same time, the diameter of the steering wheel 282 is smaller than the diameter of the through hole 12, and the steering wheel 282 is centered with the through hole 12. The drive belt 284 is made of flexible rubber material.

[0074] When an object passes through the middle position at the upper end of the I-shaped seat 1 (specifically, it can be realized by an externally connected guiding device):

[0075] First, after the drive motor 33 is powered on, it drives the pulley 34 in belt drive with it to rotate synchronously. Then, the aforementioned first roller 31 drives another rotating drum of the first roller 31 in belt drive with it to rotate. Similarly, the last first roller 31 also rotates under the action of belt drive.至此所有一号滚筒31同时进行一定速度的转动,且通过驱动带284使转向轮282在匚形板281稳定支撑下同步转动(开口槽283和环形槽32同时对驱动带284进行导向和防脱落限制);All the first rollers 31 rotate at a certain speed simultaneously, and the drive belt 284 makes the steering wheel 282 rotate synchronously under the stable support of the C-shaped plate 281 (the opening slot 283 and the annular slot 32 guide and limit the anti-drop of the drive belt 284 at the same time);

[0076] Then, the second roller 35 makes the object flow more smoothly between the working areas of the friction unit 4 and the telescopic unit 5 at the upper end of the I-shaped seat 1.之后通过呈矩形排布的齿带轮36(参考 Then, through the toothed belt pulleys 36 arranged in a rectangle (refer to Figure 2 ), drive all the connecting rods 28 and the C-shaped plates 281 thereon to rotate synchronously, and drive the toothed belt pulleys 36 rotating with its toothed belt to rotate synchronously through the toothed belt pulley 36 on the outer wall of the connecting rod 28 in the middle position (refer to Figure 3 ), specifically, an externally connected motor can be used to drive the connecting rod 28 in the middle position to rotate;

[0077] Finally, by restricting the diameter of the through hole 12 to be larger than the length and diameter of the steering wheel 282, it is avoided that the through hole 12 restricts the extension or steering of the steering wheel 282, thereby affecting the stable transportation of the object by the steering wheel 282. Through the flexible drive belt 284, it rotates a corresponding angle synchronously with the C-shaped plate 281, avoiding affecting the steering of the C-shaped plate 281, and at the same time enabling the drive belt 284 after steering to always be able to rotate (that is, after the C-shaped plate 281 steers, the drive belt 284 does not affect the transmission relationship between the first roller 31 and the steering wheel 282).

[0078] Refer to Figure 4 and Figure 6It can be seen that the friction unit 4 includes: three T-columns 41, which are evenly rotatably mounted on the load-bearing plate 11; a gear 42, which is fixedly mounted on one end of the T-column 41 close to the middle position of the work-shaped seat 1; a track plate 43, which is evenly fixedly mounted on one end of the load-bearing plate 11 close to the middle position of the work-shaped seat 1; two support plates 44, which are symmetrically distributed on the upper end of the track plate 43 away from the load-bearing plate 11; a sliding block 45, which is slidably mounted on the end surface of the track plate 43 away from the load-bearing plate 11; a lifting column 46, which is fixedly mounted on the middle position of the upper end surface of the sliding block 45, and is slidably mounted with the support plate 44; a gravity wheel 47, which is rotatably mounted on the upper end of the lifting column 46, and passes through the horizontal section above the work-shaped seat 1, and the outer wall of the gravity wheel 47 is evenly provided with serpentine grooves 48;

[0079] Reference Figure 1 and Figure 6 It can be seen that a number one rack 451 meshing with the gear 42 is fixedly installed at one end of the sliding block 45 close to the gear 42, a convex rod 452 is installed at the lower end of the movable rod 52, and a number two rack 453 meshing with the gear 42 is fixedly installed at the lower end of the convex rod 452, the number two rack 453 and the number one rack 451 are respectively located on both sides of the gear 42, and the number two rack 453 is not meshed with the gear 42 in the initial state.

[0080] When the object meets the criteria:

[0081] The convex rod 452 drives the second rack 453 to move downward under the action of the movable rod 52 until the second rack 453 is meshed with the gear 42 (the second rack 453 is not meshed with the gear 42 in the initial state. When the weight of the object reaches the standard, the second rack 453 moves to the specified position and can mesh with the gear 42); thereafter, the gear 42 drives the meshed first rack 451 to move upward, and then the sliding block 45 drives the lifting rod 46 to move upward under the guidance of the support plate 44, until the gravity wheel 47 extends out of the key groove 13 and meshes with the object. The contact position of the objects is increased through the serpentine groove 48 thereon to increase the friction between the gravity wheel 47 and the object (due to the movable installation between the gravity wheel 47 and the lifting rod 46, and the gravity wheel 47 has no power source, when it moves relative to the object with large inertia, it rotates at a low speed under the action of its own gravity, and then forms a speed difference with the steering wheel 282, thereby buffering the object with large inertia), reducing the inertia of the object during transportation, avoiding the object with large inertia from colliding with the transportation track or being thrown out, and improving the integrity of the object after sorting;

[0082] The gravity wheel 47 that does not turn can limit the turning process of objects with large inertia to a certain extent, thereby better reducing the transportation speed of objects with large inertia and reducing the damage rate of objects to a certain extent;

[0083] When the object weight does not meet the standard:

[0084] The aforementioned No. 2 rack 453 does not mesh with the gear 42, the lifting rod remains in place, and the object is transported to the specified position along the specified trajectory.

[0085] Reference Figure 4 , Figure 5 and Figure 7 It can be seen that the telescopic unit 5 includes: a connecting plate 51, which is rotatably mounted on the outer wall of each connecting rod 28 through a bearing, and is located at the lower end of the toothed pulley 36, and at a forty-five degree angle with the central axis of the connecting rod 28; a movable rod 52, which is slidably mounted on the end of the connecting plate 51 away from the connecting rod 28; a receiving ball 53, which is rotatably mounted on the upper end of the movable rod 52, and the receiving ball 53 passes through the upper horizontal section of the I-shaped seat 1; a No. 1 ring 54, which is fixedly mounted on the outer wall of the movable rod 52, and is located below the upper horizontal section of the I-shaped seat 1; a reset spring 55, which is sleeved on the outer wall of the movable rod 52, and its upper end is fixedly connected to the lower end face of the No. 1 ring 54; a No. 2 ring 56, which is fixedly mounted on the lower end of the reset spring 55, and is movably mounted on the outer wall of the movable rod 52, and the No. 1 ring 54 is located at the upper end of the connecting plate 51;

[0087] Reference Figure 6 and Figure 7 It can be seen that a positioning hole 551 is provided in the middle position where the center line of the No. 1 circular ring 54 is aligned with the center line of the connecting plate 51, and a movable column 552 is slidably installed in the positioning hole 551, and the central axis of the movable column 552 is aligned with the middle position of the lower annular sensor 518, and a No. 1 gasket 553 is fixedly installed on the outer wall of the lower end of the movable column 552, and a telescopic spring 554 sleeved on the outer wall of the movable column 552 is fixedly installed on the upper end surface of the No. 1 gasket 553, and a No. 2 gasket 555 slidably installed on the outer wall of the movable column 552 is fixedly installed on the upper end of the telescopic spring 554.

[0088] When the receiving ball 53 contacts the object and is subjected to force:

[0089] The movable rod 52 drives the fixed block 511 and the travel ball 512 to move downward synchronously, and the return spring 55 is contracted to a certain extent when it is stressed through the first ring 54 and the second ring 56, and the travel ball 512 and the guide groove 514 move relative to each other, and then the adjustment column 513 rotates a certain angle (the specific rotation angle is limited by the distance of the downward movement of the travel ball 512, and when the receiving ball 53 is not stressed, the return spring 55 drives the movable rod 52 to restore the initial position through the first ring 54 under the action of its own elastic force);

[0090] Then the central column 515 drives the annular sensor 518, and at the same time the movable column 552 moves downward synchronously with the movable rod 52 until it contacts the annular sensor 518, and the annular sensor 518 is pressed downward by the movable column 552 until the annular sensor 518 contacts the detection rod 519 after the rotation angle (and in the specific implementation process, a pressure sensor can be used as the main component of the annular sensor 518, at this time, different gears in the annular sensor 518 contact the detection rod 519 respectively, and the detection rod 519 transmits the detected signal to the external motor electrically connected to it and driving the intermediate position connecting rod 28 to rotate, thereby controlling the external motor to drive the connecting rod 28 to rotate at different angles);

[0091] Finally, the torsion spring 517 drives the annular sensor 518 to return to its initial position after turning, so that after a single measurement, the annular sensor 518 is driven to rotate a certain angle once (the torsion spring 517 itself has a certain elasticity, so when the annular sensor 518 is squeezed downward by the movable column 552, the annular sensor 518 can move downward and rotate at the same time, and the elastic coefficient of the reset spring 55 is greater than the elastic coefficient of the telescopic spring 554. When the movable column 552 moves downward too much, the movable column 552 can move upward in the positioning hole 551, thereby releasing the position limit after the movable column 552 contacts the annular sensor 518).

[0092] The working principle of the electromechanical automatic material sorting device provided by the present invention is as follows: Step 1: First, the receiving ball 53 drives the movable rod 52 to move downward to different positions, and at this time, the travel ball 512 and the guide groove 514 interact with each other to different degrees, and then the adjustment column 513 drives the dial 516 and the annular sensor 518 thereon to rotate to different angles, so that the detection rod 519 contacts different gears in the annular sensor 518, and then realizes the directional sorting of objects of different weights;

[0093] Step 2: Then, the movable rod 52 drives the first rack 451 to move downward to different positions, and then the first rack 451 and the gear 42 move relative to each other, and then the second rack 453 drives the sliding block 45 and the lifting rod thereon to move upward under the guidance of the support plate 44 under the action of the gear 42, until the gravity wheel 47 extends out of the key groove 13 and is at the same height as the steering wheel 282;

[0094] Step 3: Finally, by detecting the difference in induction signals between the detection rod 519 and the annular sensor 518 at different positions, the external motor electrically connected to the detection rod 519 and fixedly connected to a connecting rod 28 is controlled to rotate different numbers of times, so that the shaped plate 281 drives the steering wheel 282 to deflect at different angles.
