Description

Technical Field

[0001] The present invention belongs to the technical field of sorting and transportation, and particularly relates to a conveying mechanism of an automatic sorting and counting device. Background Art

[0002] The conveying mechanism of an automatic sorting and counting device is one of the core components of the entire system. It is mainly responsible for transporting items from one position to another, and realizing the sorting and counting functions during the transportation process. At the entrance end, a belt conveyor is usually used to receive goods from multiple sources, and an intelligent scanner is equipped in the middle section. Combined with a software system, classification and counting are carried out, and then it enters the sorting section. According to the destination or category, the goods are diverted to the corresponding shipping outlets through devices such as push rods and sliders. The prior art generally adopts a belt conveyor sorting device, which infers the position of an object according to the belt transmission speed, and then uses a pushing mechanism to complete the sorting and distribution of the object. Usually, the sorting mechanism does not have the function of counting.

[0003] The Chinese patent document with the publication number CN213558482U proposes a sorting mechanism for a logistics automatic sorting device. Through the settings of a fixed seat, a roller bearing, a support rod, a protective block, a connecting rod, a fastening frame and a counter, the counter can count the logistics objects during the process of sorting the logistics objects to judge the number of objects. However, due to the fluctuation of the rotational speed of the motor driving the conveyor belt, after the belt is used for a long time, its error will gradually accumulate. Sometimes, the object will also deviate during the placement and transportation process, resulting in the sorting system misjudging the orientation of the object, and then sorting the object to the wrong area. The objects sorted to the wrong area due to the influence of the error cannot be counted or are miscounted, resulting in the problem that the counted quantity of the objects after sorting will be incorrect.

[0004] Therefore, the present invention proposes a conveying mechanism of an automatic sorting and counting device, which solves the problem in the prior art that when using a counter to count the passing objects, the objects sorted to the wrong area due to the influence of the error cannot be counted or are miscounted, resulting in the incorrect counted quantity of the objects after sorting. By combining image recognition detection with an interception and distribution component, after image recognition, the system makes the interception and distribution component work to open the sorting channel, and at the same time intercepts the conveying channel, ensuring that the sorted objects must pass through this sorting channel for sorting and output, which is convenient for avoiding errors.

[0033] Embodiment 1

[0034] Please refer to Figures 1 to 13, the present invention provides a technical solution: a conveying mechanism of an automatic sorting and counting device, including an object conveyor belt assembly 1. There are multiple groups of the object conveyor belt assemblies 1. A sorting swing wheel assembly 11 is arranged between the multiple groups of object conveyor belt assemblies 1. Object output assemblies 2 are arranged on both sides of the sorting swing wheel assembly 11. An object input assembly 3 is arranged at the front end of the object conveyor belt assembly 1. The conveying mechanism of this automatic sorting and counting device further includes an automatic sorting control system. The automatic sorting control system is composed of an image detection module 4, an object return module 5, an error interception module 6, and a sorting and counting module 7. It is arranged above the object input assembly 3. The object return module 5 is arranged inside the object input assembly 3. The error interception module 6 is arranged at one end of the object conveyor belt assembly 1. The sorting and counting module 7 is arranged at one end of the object output assembly 2. The automatic sorting control system further includes a signal receiving module, a processing module, and a signal output module. The object return module 5 includes a return execution motor 51 symmetrically and fixedly installed above the support frame of the object input assembly 3. Return push plates 52 are symmetrically and rotatably installed inside the support frame of the object input assembly 3. The upper ends of the rotating shafts of the return push plates 52 are respectively fixedly connected to the lower ends of the output shafts of the return execution motor 51. An auxiliary turning triangular grid 53 is arranged on one side of the return push plate 52. The auxiliary turning triangular grid 53 is rotatably installed inside the support frame of the object input assembly 3. A gear set that meshes with each other is arranged on the outer surface of the rotating shaft of the auxiliary turning triangular grid 53 and the outer surface of the rotating shaft of the return push plate 52. An activity roller 531 is movably installed inside the auxiliary turning triangular grid 53. A centering limit plate 54 is arranged on the other side of the return push plate 52. One end of the centering limit plate 54 is rotatably connected to the inside of the support frame of the object input assembly 3. An elastic plate 521 is fixedly installed at the end of the return push plate 52 close to the centering limit plate 54. A reset spring rod 541 is arranged on the rear side surface of the centering limit plate 54. One end of the reset spring rod 541 is rotatably connected to the inside of the support frame of the object input assembly 3. The other end of the reset spring rod 541 is slidably connected to the back surface of the centering limit plate 54. A buffer plate 542 is rotatably installed on the front side surface of the centering limit plate 54 close to the return push plate 52. An elastic folding plate 543 is fixedly installed on the other side of the front side surface of the centering limit plate 54. The side surface of the elastic folding plate 543 is fixedly connected to the rear side surface of the buffer plate 542;

[0035] In this embodiment, it should be noted that the image detection module 4 is used to perform image detection on the object and convert the image detection result into an electrical signal, and the processor mainly processes the received electrical signal. The receiving unit is used to receive the electrical signals transmitted from the image detection module 4, the first pressure sensor 6211, the second pressure sensor 6221, the third pressure sensor 64, and the photoelectric sensor 65. The processing unit is used to process the electrical signals received by the receiving unit. The output unit is used to output the electrical signals processed by the processing unit. The output ends of the image detection module 4, the third pressure sensor 64, the photoelectric sensor 65, the first pressure sensor 6211, and the second pressure sensor 6221 are electrically connected to the input end of the receiving unit respectively. The output end of the receiving unit is electrically connected to the input end of the processing unit. The input end of the output unit is electrically connected to the output end of the processing unit. The input ends of the object conveyor belt assembly 1, the object output assembly 2, the object input assembly 3, the return execution motor 51, the interception execution motor 61, and the sorting output execution motor 71 are electrically connected to the output end of the output unit respectively, and are all controlled by the electrical signals of the automatic sorting control system. Among them, the sorting swing wheel assembly 11 and the error interception module 6 are independently controlled by the automatic sorting control system respectively. In addition, it should be noted that the return execution motor 51, the interception execution motor 61, and the sorting output execution motor 71 can use motors of model YL and be used with a control switch of model SB16. The input ends of the return execution motor 51, the interception execution motor 61, and the sorting output execution motor 71 all refer to the input ends of the control switch. The third pressure sensor 64, the second pressure sensor 6221, and the first pressure sensor 6211 can use industrial-grade pressure sensors of the 86 series. The specific control process is as follows: The object is conveyed to the lower part of the image detection module 4 through the object input assembly 3 for detection. The image detection module 4 performs image detection on the object and outputs the image detection result. The control system, according to the feedback image detection result, makes the interception execution motor 61 control the interception grid 62 to rotate to cancel the interception of the entrance of the corresponding object output assembly 2, and at the same time, the interception grid 62 rotates to the front end of the next section of the object conveyor belt assembly 1 to intercept the continuous conveyance of the object. When the object is conveyed here, the control system controls the sorting swing wheel assembly 11 to swing, and outputs the object from the object conveyor belt assembly 1 to the corresponding object output assembly 2. Coupled with the interception of the subsequent conveyance channel by the interception grid 62, the object is forced to enter the corresponding object output assembly 2 for sorting and output. Since the sorting swing wheel assembly 11 and the interception execution motor 61 are independently controlled respectively, errors can be avoided;

[0036] In this embodiment, the return execution motor 51 is also controlled by the automatic sorting control system. Under normal circumstances, the return push plate 52 is in the initial state of being retracted inside the support frame of the object input component 3. At this time, the return push plate 52 and the elastic plate 521 push and squeeze the buffer plate 542 and the centering limit plate 54, so that the centering limit plate 54 is unfolded as a whole, presenting an inverted V shape. When an object passes by, it can play a role in limiting the object, making the object pass through the image detection module 4 as much as possible from the middle, and trying to ensure the integrity of the object image detection. However, when the object cannot pass through the image detection module 4 to detect an effective result due to incorrect placement posture or the surface with the identification being covered, the automatic sorting control system will report an error. At the same time, the automatic sorting control system will control the return execution motor 51 to work. The return execution motor 51 drives the return push plate 52 to rotate towards the side away from the image detection module 4. At this time, the front end of the return push plate 52 and the elastic plate 521 cancel the extrusion of the centering limit plate 54 and the buffer plate 542. The reset spring rod 541 will push the centering limit plate 54 to flip towards the side of the return push plate 52. At this time, the elastic folding plate 543 will rebound to make the buffer plate 542 generate an effective pushing action on the object, so that the object is pushed to the inside of the elastic plate 521. As the return push plate 52 rotates, the elastic plate 521 will take the object out. At the same time, as the return push plate 52 rotates, driven by the gear set, the auxiliary turning triangular grid 53 will rotate in the direction opposite to the auxiliary turning triangular grid 53. A shovel plate is provided at the lower end of the return push plate 52. The opposite rotation of the return push plate 52 and the auxiliary turning triangular grid 53 causes the object to be shoveled up and contact the bottom triangular crossbar of the auxiliary turning triangular grid 53, and is turned over under the cooperation of the movable roller 531 for posture adjustment. Then, the return execution motor 51 works to drive the return push plate 52 and the auxiliary turning triangular grid 53 to rotate in the reverse direction and reset respectively. During this process, the object is pushed backward by the auxiliary turning triangular grid 53, and then passes through the return push plate 52 and the centering limit plate 54 again and is guided into the lower part of the image detection module 4 for image detection. It should be noted that if the same object fails to pass the detection three times, the automatic sorting control system feeds back the error information of the object, and other mechanisms or manual intervention are required to remove the incorrect object, so as to maximize the automation degree and efficiency of the automatic detection and sorting of objects, and improve the accuracy rate of object detection and sorting.

[0037] Embodiment 2

[0038] Please refer to Figures 1 to 13, on the basis of the first embodiment, this embodiment further proposes that the error interception module 6 includes an interception execution motor 61 symmetrically and fixedly installed above the support frame of the object conveyor belt assembly 1. The support frame of the object conveyor belt assembly 1 is symmetrically and rotatably installed with an interception grid plate 62. An active roller mounting frame 63 is movably installed inside the interception grid plate 62. An active groove adapted to the active roller mounting frame 63 is provided inside the interception grid plate 62. Symmetrically and fixedly installed on both sides of the active roller mounting frame 63 are return springs 631. One end of the return spring 631 is fixedly connected to the side wall of the active groove of the interception grid plate 62. Fixed rollers 632 are evenly distributed in the middle of the active roller mounting frame 63. Pressure balls 633 are respectively fixedly installed at both ends of the active roller mounting frame 63. Side mounting plates one 621 and two 622 are respectively fixedly installed on both sides of the interception grid plate 62 by bolts. Pressure sensors one 6211 and two 6221 are respectively fixedly installed on the inner surfaces of the side mounting plates one 621 and two 622 at positions adapted to the pressure balls 633. A light buffer ring 6322 is rotatably installed outside the fixed roller 632. A rubber roller 6321 is fixedly installed on the outer surface of the light buffer ring 6322. A through groove is provided on the side wall of the interception grid plate 62. Arc-shaped pads are fixedly installed on the inner surfaces of the side mounting plates one 621 and two 622;

[0039] In this embodiment, the interception execution motor 61 is installed on the side support plate on the input direction side of the object conveyor belt assembly 1, which intercepts the previous group of sorting swing wheel assemblies 11. Each group of interception execution motors 61 is individually numbered. The automatic sorting control system can control the corresponding numbered interception execution motor 61 to start according to the image detection result. Since there are multiple groups of the error interception module 6, sorting swing wheel assemblies 11, object output assemblies 2, and object conveyor belt assemblies 1, taking one group as an example, the working process is described as follows. When an object is detected and recognized by the image, the automatic sorting control system outputs a control signal, calculates the time for the object to reach the corresponding position of the object output assembly 2 according to the transportation speed of the object conveyor belt assembly 1, and then controls the corresponding sorting swing wheel assembly 11 to swing and sort the object through the object conveyor belt assembly 1 and guide it into the corresponding object output assembly 2. During this process, the automatic sorting control system will also output a control signal according to the image detection result and separately output a control signal to the interception execution motor 61 of the group behind the corresponding object output assembly 2. The interception execution motor 61 rotates the interception grid plate 62 clockwise before the sorting swing wheel assembly 11 sorts the object, cancels the interception of the corresponding object output assembly 2, and after rotation, remains perpendicular to the position of the next group of object conveyor belt assemblies 1 to intercept the next group of object conveyor belt assemblies 1. Under normal circumstances, the automatic sorting control system outputs to the sorting swing wheel assembly 11 and the interception execution motor 61 respectively without error, and the object will be directly sorted and guided to the corresponding object output assembly 2 for output through the sorting swing wheel assembly 11. Once an error occurs, for example, due to the transportation speed error of the object conveyor belt assembly 1, the automatic sorting control system controls the sorting swing wheel assembly 11 at the wrong position to start, but the numbered interception execution motor 61 here will not open, and the interception grid plate 62 will intercept the entrance of the object output assembly 2 here. Even if the object is sorted and exported by the sorting swing wheel assembly 11 at the wrong position when passing through, it will only be intercepted by the interception grid plate 62. At this time, the object will collide with the side mounting plate one 621 surface of the interception grid plate 62 here, and the rubber roller 6321 is collided and squeezed, causing the movable roller mounting frame 63 to move as a whole towards the side mounting plate two 622 side. At this time, the pressure ball 633 will generate a pressure touch on the pressure sensor two 6221 mounted on the side mounting plate two 622, causing the pressure sensor two 6221 to generate a signal. The signal output of the pressure sensor two 6221 is fed back to the automatic sorting control system to generate an error signal, and the automatic sorting control system will control the numbered interception execution motor 61 here to start working. As the interception grid plate 62 rotates clockwise, the intercepted object can be pushed to the next object conveyor belt assembly 1 to continue transportation until it reaches the correct position for sorting, achieving the purpose of error correction. This is for the situation where the automatic sorting control system controls the wrong sorting swing wheel assembly 11 to open in advance. Another kind of error is that the object has reached the correct object output assembly 2,At this time, the interception grille 62 at this location has intercepted the subsequent object conveyor belt assembly 1. However, the corresponding sorting swing wheel assembly 11 at this location has not started the swinging operation due to a calculation error in the automatic sorting control system. At this time, the object will directly collide with the side mounting plate two 622 of the interception grille 62 at this location. The rubber roller 6321 is collided and squeezed, causing the entire movable roller mounting bracket 63 to move toward the side mounting plate one 621. At this time, the pressure ball 633 will exert pressure on the pressure sensor one 6211 mounted on the side mounting plate one 621, triggering a signal from the pressure sensor one 6211. The signal output of the pressure sensor one 6211 is fed back to the automatic sorting control system to generate an error signal. The automatic sorting control system will control the interception execution motor 61 with the corresponding number at this location to start working for early reset. As the interception grille 62 rotates counterclockwise, the intercepted object can be pushed to the correct position, and the object output assembly 2 is driven to complete the sorting and conveying, thus achieving the purpose of error correction. This two-way error interception and correction design can basically solve the problem in the prior art that the sorting system misjudges the orientation of the object and then sorts the object to the wrong area;

[0040] In this embodiment, the side mounting plate one 621 and the side mounting plate two 622 respectively function to mount the pressure sensor two 6221 and the pressure sensor two 6221. Moreover, the arc-shaped pads of the side mounting plate one 621 and the side mounting plate two 622 are inserted into the through slots of the interception grille 62, which not only plays a positioning role in the installation of the side mounting plate one 621 and the side mounting plate two 622, but also the arc-shaped pads can play a certain buffering role. The return spring 631 on the movable roller mounting bracket 63 mainly functions to help the movable roller mounting bracket 63 return to its original position. The fixed roller 632 rotatably mounts the rubber roller 6321 through the lightweight buffer ring 6322, which not only plays a buffering role, but also the rubber roller 6321 can freely rotate to play a certain guiding role for the object.

[0041] Embodiment Three

[0042] Please refer to Figures 1 to 13 Based on Embodiment Two, this embodiment further proposes that a pressure sensor three 64 is fixedly installed on the inner surface of the object conveyor belt assembly 1. Magnetic attraction blocks one are symmetrically arranged on the upper and lower sides of the pressure sensor three 64. A magnetic attraction block two adapted to the magnetic attraction block one is arranged on the side surface of one end of the interception grille 62. An optoelectronic sensor 65 is fixedly installed above the side surface of the object output assembly 2;

[0043] In this embodiment, the photoelectric sensor 65 mainly senses the objects that have entered the object output component 2. Once an object has entered the object output component 2, the photoelectric sensor 65 outputs a signal at this time, and the automatic sorting control system will receive the signal and control the corresponding intercept execution motor 61 to work to reset and close the intercept grid plate 62 here. The pressure sensor III 64 mainly generates a pressure signal when the intercept execution motor 61 controls the intercept grid plate 62 to reset, so as to feedback and monitor whether the intercept grid plate 62 is fully reset, and outputs a signal to the automatic sorting control system. At this time, the automatic sorting control system controls the sorting output execution motor 71 to work to drive the intercept plate 72 to flip, and the object leaves the object output component 2. Only then is the object sorting completed. This is to avoid object sorting errors when the intercept grid plate 62 fails to close. The intercept plate 72 can serve as the last line of defense to intercept the objects with object sorting errors caused by the failure of the intercept grid plate 62, facilitating timely discovery and manual intervention to solve the problem.

[0044] Embodiment Four

[0045] Please refer to Figures 1 to 13 , on the basis of Embodiment Three, this embodiment also proposes that the sorting counting module 7 includes a sorting output execution motor 71 fixedly installed below the outer surface of the object output component 2. An intercept plate 72 is rotatably installed below the inner surface of the object output component 2. One end of the rotating shaft of the intercept plate 72 is fixedly connected to the output shaft of the sorting output execution motor 71. A counter 73 is fixedly installed above the inner surface of the object output component 2;

[0046] In this embodiment, the sorting output execution motor 71 and the intercept plate 72 serve as the last line of defense to intercept the objects in case of failure of the intercept grid plate 62. The counter 73 can adopt a photoelectric sensor counter to automatically count the passing objects.

[0047] Embodiment Five

[0048] Please refer to Figures 1 to 13 , on the basis of Embodiment Four, this embodiment also proposes a usage method for the conveying mechanism of an automatic sorting counting device, including the following steps:

[0049] Step 1, object input. The object is conveyed through the object input component 3 to be detected below the image detection module 4. The image detection module 4 performs image detection on the object and outputs the image detection result. The automatic sorting control system controls the corresponding numbered intercept execution motor 61 to start according to the image detection result, and the intercept execution motor 61 controls the intercept grid plate 62 to rotate to cancel the interception of the entrance of the corresponding object output component 2;

[0050] Step 2: Object sorting. The automatic sorting control system calculates the time for the object to reach the position of the corresponding object output component 2 according to the transportation speed of the object conveyor belt component 1, and then outputs a control signal to control the corresponding sorting swing wheel component 11 to swing and work, so that the object is sorted and guided into the corresponding object output component 2 through the object conveyor belt component 1;

[0051] Step 3: Reset the intercepting grille 62. The photoelectric sensor 65 senses the object that has entered the object output component 2. When the object has entered the object output component 2, the photoelectric sensor 65 outputs a signal at this time. The automatic sorting control system will receive the signal and control the corresponding intercepting execution motor 61 to work to reset and close the intercepting grille 62 here;

[0052] Step 4: Object output. When the intercepting grille 62 is reset, the pressure sensor three 64 generates a pressure signal and outputs the signal to the automatic sorting control system. At this time, the automatic sorting control system controls the sorting output execution motor 71 to work to drive the intercepting plate 72 to flip, so that the object leaves through the intercepting plate 72, and the object sorting is completed. The counter 73 is a counter that can automatically count the objects passing through.

The scope of the present invention is defined by the appended claims and their equivalents.
