Description

Technical Field

[0001] The present invention relates to a sorting and packaging device, in particular to an automatic sorting and packaging device for conveying articles, belonging to the technical field of article sorting and packaging. Background Art

[0002] In logistics work, different items need to be sorted and packaged frequently. The current solutions are mostly conveyors in conjunction with robotic arms. The conveyors gradually send the items under the robotic arms, and the robotic arms clamp the items and put them into packaging boxes. Although it has a certain degree of automation, it is not intelligent enough and cannot classify and package items according to their shapes.

[0003] A Chinese patent with authorization announcement number CN214391185U discloses an automatic packaging sorting device, which specifically includes an article conveyor belt, an information table cleaning mechanism and an image acquisition mechanism. Conveyor belt bracket baffles are movably connected at both ends of the article conveyor belt, the information table cleaning mechanism is connected to the outer surface of the conveyor belt bracket baffle, the image acquisition mechanism is arranged on one side of the information table cleaning mechanism, and an article diversion channel is opened on one side surface of the conveyor belt bracket baffle. Fixing bolts are passed through one end of the hydraulic cylinder, and a push plate is connected to one end of the push rod. In the automatic packaging sorting device, the cleaning sponge rotates to clean the information QR code or table pasted on the surface of the article, which is beneficial to avoid dust and other impurities from blocking the information QR code or table, and facilitates the image collector body to recognize information, and the flexible cotton continuously wipes the camera part of the image collector body during the rotation process, thereby improving the accuracy of the sorting device during operation.

[0004] It can be understood that the technical solution disclosed in the above patent mainly identifies the information of the item through an image collector, and then classifies and packs the item according to the type of item, which improves the intelligence level to a certain extent. However, this sorting and packing method still has some shortcomings when used. On the one hand, it mainly relies on identifying information codes to classify items, and the information code cannot be guaranteed to always face upwards, and may need to be manually flipped, which affects the overall intelligence and automation level. On the other hand, the above patent does not have a clamping and transfer structure for items, and the clamping and transfer structure in the prior art usually relies on a robotic arm or octopus claw, which has poor applicability. The clamping effect for some irregular, spherical or soft packages is general, and may fall off. Excessive clamping force may also cause damage to the package. In response to the above problems, we propose an automatic sorting and packing device for item transportation. Summary of the invention

[0005] The purpose of the present invention is to provide an automatic sorting and packaging device for article transportation in order to solve the above-mentioned problems. The device can intelligently sort and package articles according to their shapes, has a highly adaptable clamping and transfer function, and has a high degree of intelligence and adaptability.

[0006] The present invention achieves the above-mentioned purpose through the following technical scheme: an automatic sorting and packaging device for conveying articles, comprising a first conveyor, a second conveyor, a third conveyor, a lower slide and a lifting storage rack, two groups of side brackets extending upward are fixedly installed on the front and rear side walls of the first conveyor, a suspended plate is fixed between the two side brackets, and a visual camera for detecting the shape, posture and position of the articles below is arranged on one side of the bottom of the two suspended plates. The first conveyor is used for centralized conveying of all articles, and square, spherical and irregular shaped articles can be directly placed on one side of the first conveyor. There are two visual cameras, one side is used to collect information of articles just placed on the first conveyor, determine the shape type of the articles after collecting the information, and then transfer them to the front, middle and rear sides of the first conveyor for processing according to their shapes, and the other side is used to determine whether the articles have entered the required position to play a verification role.

[0007] The second conveyor is located at the middle position of one side of the first conveyor, and is used for conveying square objects. The third conveyor is located at the front position of one side of the first conveyor, and is used for conveying square and irregular objects. The lower slide is located at the rear position of one side of the first conveyor, and is used for conveying spherical objects. The lifting storage rack is located below the discharge port of the lower slide, and is used for temporary storage of spherical objects. The spherical objects can slide into the lifting storage rack through the lower slide. First, the square objects are placed. The square objects have a regular shape and strong stability, so they are highly flexible when transferred to the storage box. They only need to be stacked step by step according to the space in the storage box. The spherical objects and irregular objects can be temporarily stored on the lifting storage rack and the third conveyor. After the square objects are stored as a whole, the sizes of other unpacked spherical objects or irregular objects are measured, and then the storage plan is planned according to the remaining gap in the storage box. It is highly intelligent and can package objects of different shapes more efficiently.

[0008] A first motor with an output shaft facing downward is installed on the side wall of the first conveyor through a reinforcement bracket, a transverse electric push rod is connected to the output shaft of the first motor, a longitudinal electric push rod with a telescopic end facing downward is fixed to the telescopic end of the transverse electric push rod, a second motor is fixed to the telescopic end of the longitudinal electric push rod, a transversely telescopic U-shaped bracket is connected to the telescopic end of the second motor, a rotary position changing motor is installed on both ends of the U-shaped bracket, a multi-contact clamping piece is connected to the output shaft of the rotary position changing motor, and each contact of the two multi-contact clamping pieces can be used to adaptively clamp square objects, spherical objects and irregular objects.

The rotation of the mounting plate is controlled by the rotary position changing motor. When the spherical object needs to be clamped, it is only necessary to control the arc-shaped grooves of the two mounting plates to face each other, and then control the two mounting plates to move to both sides of the spherical object and then control the U-shaped bracket to contract, so that the spherical object is clamped into the arc-shaped grooves of the two mounting plates, and then the spherical object is sent to the position where it needs to be placed and packaged. In order to prevent the spherical object from moving sideways in the arc-shaped groove, an anti-slip pad can be provided in the arc-shaped groove, and the extension and retraction control of the U-shaped bracket can adopt electric drive to control the contraction, so as to adaptively control the clamping of the object.

[0010] Preferably, a plurality of arc-shaped protrusions are evenly arranged on the side wall of the mounting disk for adaptively clamping soft-packaged items, the protrusion heights of each arc-shaped protrusion are different, and the surface of the arc-shaped protrusion is provided with an anti-slip coating as a second contact point for clamping soft items, such as bagged logistics products. When the soft items need to be clamped and fixed, the position of the mounting disk is adjusted by rotating the position changing motor so that the arc-shaped protrusions on the two mounting disks face each other, and then the two mounting disks are controlled to move to both sides of the soft items and the U-shaped bracket is controlled to retract so that the soft items are clamped by the arc-shaped protrusions on both sides. Considering that the mounting disk also has a pneumatic telescopic rod, when the arc-shaped protrusion needs to be used to clamp the soft items, the pneumatic telescopic rod needs to be kept retracted to prevent the arc-shaped protrusion from failing to descend to the side of the item.

[0011] Preferably, the outer wall of the mounting plate is provided with a planar groove, a plurality of pneumatic telescopic rods are fixedly arranged on the planar groove, and the telescopic ends of the pneumatic telescopic rods are provided with hemispherical anti-slip sheets as third contacts.

Since the inflation space is shared, the telescopic distances of each pneumatic telescopic rod do not need to be consistent, and the pneumatic telescopic rods have a high degree of adaptability. When the pneumatic telescopic rods are inflated, the telescopic distances of each pneumatic telescopic rod can be adapted according to the shape of the object, so as to ensure that each anti-slip sheet is pressed against the outer surface of the object.

[0012] Preferably, side pushing mechanisms that can push articles toward the middle position of the first conveyor are fixedly provided on the front and rear side walls of the first conveyor, and the side pushing mechanisms include a fixing plate fixedly installed on the side wall of the first conveyor, a plurality of upper extension brackets arranged on one side of the fixing plate, and a mounting plate fixed on each of the upper extension brackets at the same time, and a second electric push rod is installed on the side of the mounting plate facing the middle position of the first conveyor, and a movable plate is connected to the telescopic end of the second electric push rod, which is used to push articles to the center position of the first conveyor, and the movement of the movable plate is controlled by the second electric push rod. In specific use, after the visual camera identifies the type of article, it determines the position where the article needs to be transferred according to the type of article, and then controls the movement of the movable plate on the front or rear side, so that the article can be pushed to the front and transported to the third conveyor, the article can be pushed to the middle and transported to the second conveyor, and the article can be pushed to the back and transported to the lower slide, so as to realize the article sorting function.

[0013] Preferably, a shovel blade is provided on one side of the bottom of the movable plate for shoveling up the bottom of the article to avoid excessive friction between the article and the first conveyor resulting in direct push of the packaging wear. The shovel blade can scoop up the article appropriately to improve the smoothness of pushing.

[0014] Preferably, a reinforced telescopic rod is further provided between the movable plate and the mounting plate. The provision of the reinforced telescopic rod effectively ensures the structural stability of the movable plate, avoids the design deviation of the single electric push rod, and improves stability.

[0015] Preferably, the lifting storage rack includes a fixed base, a third electric push rod installed at the center position of the top of the fixed base, and a storage bucket arranged on the telescopic end of the top of the third electric push rod. A reinforced telescopic connecting rod is arranged between the bottom of the storage bucket and the fixed base. The third electric push rod can push the storage bucket to move up and down, which is used to lift spherical objects in the storage bucket, making it easier for the clamping structure to clamp the spherical objects.

[0016] Preferably, the second conveyor and the third conveyor are both equipped with a partition assembly for temporarily stopping the conveyance of articles, the partition assembly includes a first electric push rod fixed on the side wall of the first conveyor or the second conveyor, an L-shaped connecting rod fixedly arranged on the top telescopic end of the first electric push rod, and a partition plate fixed at one end of the L-shaped connecting rod, the partition plate is located directly above the conveyor belt of the third conveyor or the second conveyor, and the separation plate is raised and lowered by the first electric push rod. When the separation plate is raised, articles can move on the conveyor belt. When the articles need to be clamped, the separation plate is controlled to descend to prevent the articles from moving.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 10 As shown, an automatic sorting and packaging device for conveying articles comprises a first conveyor 1, a second conveyor 3, a third conveyor 4, a lower slide 5 and a lifting storage rack 7. Two groups of side brackets 9 extending upward are fixedly installed on the front and rear side walls of the first conveyor 1, and a suspended plate 10 is fixed between the two side brackets 9. A visual camera 11 for detecting the shape, posture and position of the articles below is arranged on one side of the bottom of the two suspended plates 10. The first conveyor 1 is used for centralized conveying of all articles. Square, spherical and irregular shaped articles can be directly placed on one side of the first conveyor 1. There are two visual cameras 11, one side is used to collect information of articles just placed on the first conveyor 1, determine the shape type of the articles after collecting the information, and then transfer them to the front, middle and rear sides of the first conveyor 1 for processing according to their shapes, and the other side is used to determine whether the articles have entered the required position to play a verification role.

[0033] The second conveyor 3 is located at the middle position of one side of the first conveyor 1, and is used for conveying square objects. The third conveyor 4 is located at the front end position of one side of the first conveyor 1, and is used for conveying square and irregular objects. The lower slide 5 is located at the rear end position of one side of the first conveyor 1, and is used for conveying spherical objects. The lifting storage rack 7 is located below the discharge port of the lower slide 5, and is used for temporary storage of spherical objects. The spherical objects can slide into the lifting storage rack 7 through the lower slide 5. In actual application, the present application is mainly used in the logistics industry, and is used for sorting small objects, most of which are square objects. First, Square objects are placed. Square objects have regular shapes and strong stability. They are highly flexible when transferred to the storage box 6. They only need to be gradually stacked according to the space in the storage box 6. Spherical objects and irregular objects can be temporarily stored on the lifting storage rack 7 and the third conveyor 4. After the square objects are stored as a whole, the sizes of other unpacked spherical objects or irregular objects collected by the visual camera 11 are obtained, and then the storage plan is planned according to the remaining gap in the storage box 6. It is highly intelligent and can pack objects of different shapes more efficiently.

[0034] A first motor 13 with an output shaft facing downward is installed on the side wall of the first conveyor 1 through a reinforcement bracket 12, and a transverse electric push rod 14 is connected to the output shaft of the first motor 13, and a longitudinal electric push rod 15 with a telescopic end facing downward is fixed to the telescopic end of the transverse electric push rod 14, and a second motor 21 is fixed to the telescopic end of the longitudinal electric push rod 15, and a transversely retractable U-shaped bracket 16 is connected to the telescopic end of the second motor 21, and a rotary position changing motor is installed at both ends of the U-shaped bracket 16, and a multi-contact clamping piece 8 is connected to the output shaft of the rotary position changing motor, and each contact of the two multi-contact clamping pieces 8 can be used to adaptively clamp square objects, spherical objects and irregular objects.

[0035] The above structure constitutes a clamping assembly that can swing back and forth and can carry articles up and down. The multi-contact clamping pieces 8 on both sides cooperate to clamp different types of articles. The first motor 13, the transverse electric push rod 14 and the longitudinal electric push rod 15 are adjusted to clamp the articles in the second conveyor 3, the third conveyor 4 and the lifting storage rack 7 and then send them to the storage box 6. The two multi-contact clamping pieces 8 cooperate to clamp the articles. Whether they are spherical, square or irregular objects, they can be adaptively clamped and fixed. Compared with the existing octopus claw structure, clamping is achieved by different types of contacts on the multi-contact clamping piece 8. The clamping state is more stable and not easy to fall off. Especially for irregular objects, it is not only highly adaptable, but also will not scratch the packaging of the articles.

[0036] The multi-contact clamping piece 8 includes a mounting plate 801 connected to the output shaft of the rotary position-changing motor. The side of the mounting plate 801 is provided with an arc-shaped slot 802 composed of a plurality of arc-shaped slots with different diameters. The arc-shaped slot 802 serves as a first contact point and is used to adaptively clamp spherical objects with different diameters. When the present application is actually used, the rotation of the mounting plate 801 is controlled by the rotary position-changing motor. When the spherical object needs to be clamped, it is only necessary to control the arc-shaped slots 802 of the two mounting plates 801 to face each other, and then control the two mounting plates 801 to move to the two sides of the spherical object and then control the U-shaped bracket 16 to contract, so that the spherical object is clamped into the two mounting plates 80 1, and then the spherical objects are sent to the position where they need to be placed and packaged. In order to prevent the spherical objects from moving sideways in the arc-shaped card slot 802, an anti-skid pad can be set in the arc-shaped card slot 802. The telescopic control of the U-shaped bracket 16 can adopt electric drive control to shrink, and can adaptively clamp and control the objects. At the same time, a visual camera 11 is also installed at the bottom of the U-shaped bracket 16 to collect the remaining space in the storage box 6 and the shape and size of each object. It is used to measure the size of other unpackaged spherical objects or irregular objects after the square objects are stored as a whole, so as to plan the storage plan according to the remaining gap of the storage box 6.

[0037] A plurality of arc-shaped protrusions 803 are evenly arranged on the side wall of the mounting plate 801 for adaptively clamping soft-packaged items. The protrusion heights of each arc-shaped protrusion 803 are different, and the surface of the arc-shaped protrusion 803 is provided with an anti-slip coating as a second contact point for clamping soft items, such as bagged logistics products. When the soft items need to be clamped and fixed, the position of the mounting plate 801 is adjusted by rotating the position changing motor so that the arc-shaped protrusions 803 on the two mounting plates 801 face each other, and then the two mounting plates 801 are controlled to move to the two sides of the soft items and then the U-shaped bracket 16 is controlled to retract so that the soft items are clamped by the arc-shaped protrusions 803 on both sides. Considering that the mounting plate 801 also has a pneumatic telescopic rod 804, when the arc-shaped protrusion 803 needs to be used to clamp the soft items, the pneumatic telescopic rod 804 needs to be kept retracted to prevent the arc-shaped protrusion 803 from failing to descend to the side of the item.

[0038] The outer wall of the mounting plate 801 is provided with a planar groove, on which a plurality of pneumatic telescopic rods 804 are fixedly arranged, and the telescopic ends of the pneumatic telescopic rods 804 are provided with hemispherical anti-skid sheets 805 as third contacts. The mounting plate 801 is also provided with an integrated air pump 806 for extracting and exhausting air, and the air pump 806 is simultaneously connected to each of the pneumatic telescopic rods 804 through a common pipeline, so that the pneumatic telescopic rods 804 share the inflation space, and the air pump 806 is used to control the inflation and deflation of each of the pneumatic telescopic rods 804 at the same time. Since the inflation space is shared, the telescopic distances of the pneumatic telescopic rods 804 do not need to be consistent, and the pneumatic telescopic rods 804 have a high degree of adaptability. When the pneumatic telescopic rods 804 are inflated, the telescopic distances of the pneumatic telescopic rods 804 can be adapted according to the shape of the object, and it is ensured that each anti-skid sheet 805 is pressed against the outer surface of the object. This structural design can not only effectively clamp and fix square objects, but also adaptively clamp irregular shaped objects.

[0039] Side pushing mechanisms 2 that can push articles to the middle position of the first conveyor 1 are fixedly arranged on the front and rear side walls of the first conveyor 1. The side pushing mechanism 2 includes a fixing plate 201 fixedly installed on the side wall of the first conveyor 1, a plurality of upper extension brackets 202 arranged on one side of the fixing plate 201, and a mounting plate 203 fixed on each upper extension bracket 202 at the same time. A second electric push rod 204 is installed on the side of the mounting plate 203 facing the middle position of the first conveyor 1. A movable plate 205 is connected to the telescopic end of the second electric push rod 204, which is used to push articles to the center position of the first conveyor 1. The movement of the movable plate 205 is controlled by the second electric push rod 204. In specific use, after the visual camera 11 identifies the type of article, it determines the position where the article needs to be transferred according to the type of article, and then controls the movement of the movable plate 205 on the front or rear side. The article can be pushed to the front and transported to the third conveyor 4, and the article can be pushed to the middle and transported to the second The conveyor 3 pushes the articles to the rear and can convey them to the lower slide 5 to realize the article sorting function. A shovel blade 206 is arranged on one side of the bottom of the movable plate 205 for shoveling the bottom of the articles to avoid excessive friction between the articles and the first conveyor 1, which causes direct pushing of the packaging and wear. The shovel blade 206 can shovel the articles appropriately to improve the pushing smoothness. A reinforced telescopic rod 207 is also arranged between the movable plate 205 and the mounting plate. The setting of the reinforced telescopic rod 207 effectively ensures the structural stability of the movable plate 205, avoids the design of the single electric push rod from being offset, and has stronger stability. In addition, considering that in actual use, there may be a situation where the first conveyor 1 continues to convey the spherical articles into the storage bucket 703 when the storage bucket 703 is raised to transport the spherical articles, in order to avoid that the subsequent spherical articles cannot be effectively sorted, the subsequent spherical articles can be temporarily clamped by the side push mechanism 2 until the spherical articles in the storage bucket 703 are packaged and then released.

[0040] The lifting storage rack includes a fixed base 701, a third electric push rod 702 installed at the center of the top of the fixed base 701, and a storage hopper 703 arranged on the telescopic end of the top of the third electric push rod 702. A reinforced telescopic connecting rod 704 is arranged between the bottom of the storage hopper 703 and the fixed base 701. The third electric push rod 702 can push the storage hopper 703 to lift and move, so as to lift the spherical items in the storage hopper 703, facilitating the clamping structure to clamp the spherical items.

[0041] Separation components 17 for temporarily stopping the conveyance of items are installed on both the second conveyor 3 and the third conveyor 4. The separation component 17 includes a first electric push rod 18 fixed to the side wall of the first conveyor 1 or the second conveyor 3, an L-shaped connecting rod 19 fixed to the telescopic end of the top of the first electric push rod 18, and a separation plate 20 fixed to one end of the L-shaped connecting rod 19. The separation plate 20 is located directly above the conveyor belt of the third conveyor 4 or the second conveyor 3. The lifting of the separation plate 20 is controlled by the first electric push rod 18. When the separation plate 20 rises, the items can move on the conveyor belt. When it is necessary to clamp the items, the separation plate 20 is controlled to descend to prevent the items from moving, facilitating the clamping structure to clamp the items, and each conveyor can operate without stopping.

[0042] Working principle:

[0043] When the device is actually in use, various types of items are sequentially placed on the left side of the first conveyor 1. The first conveyor 1 conveys the items from the left side to the right side. During the conveying process, the visual camera 11 on the left side first collects the item information to confirm whether the item is square, spherical or irregular. Among them, bagged items belong to irregular items. Then, the moving plate 205 of the side pushing mechanism 2 is controlled to move according to the item shape. The irregular items are pushed forward and conveyed to the third conveyor 4, the square items are pushed to the middle and conveyed to the second conveyor 3, and the spherical items are pushed to the rear and conveyed to the sliding ladder 5, and then enter the lifting storage rack 7 through the sliding ladder 5 to realize the item sorting function. After the items enter the corresponding conveying structures, the positions of the two multi-contact clamping pieces 8 are adjusted by controlling the start of the first motor 13, the horizontal electric push rod 14 and the vertical electric push rod 15. Different types of items are clamped and fixed by different contacts on the multi-contact clamping pieces 8 and then conveyed. First, the square items are placed, and they can be gradually stacked according to the space in the storage box 6. The spherical items and irregular items are temporarily stored on the lifting storage rack 7 and the third conveyor 4. After the square items are integrally stored, the sizes of the other unpacked spherical items or irregular items are measured, and then the storage plan is planned according to the remaining gaps in the storage box 6, which has a high degree of intelligence and can pack different-shaped items more efficiently.
