Description

Technical Field

[0001] The utility model belongs to the technical field of express sorting, in particular to an automatic sorting device based on word recognition of delivery slips. Background Art

[0002] Sorting is the process in which the distribution center quickly and accurately picks the goods from their storage locations or other locations according to the customer's order requirements or distribution plan, and classifies and concentrates them in a certain way. Therefore, a sorting device is used. Traditional sorting devices require the conveyor to stop or slow down during sorting, which affects the progress and efficiency of sorting.

[0003] After searching, the Chinese patent document (authorization announcement number CN218637945U) discloses a sorting device based on visual recognition, including a conveyor belt, a frame mounted on both sides of the conveyor belt, and a partition mechanism is arranged on the frame, wherein: the partition mechanism includes a No. 1 partition plate and a No. 2 partition plate; a protrusion is arranged at the first end of the No. 1 partition plate, and a plurality of protrusions are arranged on the first side of the No. 2 partition plate. The sorting device based on visual recognition provided by the utility model uses the No. 2 partition plate to adjust the spacing between the second end of the No. 2 partition plate and the No. 1 partition plate, and a protrusion is also arranged on the No. 1 partition plate to separate the parts and generate spacing, so as to avoid the parts from being close to each other and agglomerating to interfere with visual recognition, thereby improving the visual recognition rate, and using a plurality of protrusions on the No. 2 partition plate to make the parts collide with the protrusions and rotate to squeeze the parts of the attachment to generate gaps, so as to avoid the jamming caused by the parts entering the partition mechanism in parallel. When the sorting device is sorting, the pushing mechanism is required to push the express into the discharge port, but the pushing mechanism and the discharge port are in a horizontal state, so the conveyor needs to stop or slow down, which affects the progress and efficiency of sorting. Utility Model Content

[0004] The utility model aims to provide an automatic sorting device based on face sheet text recognition to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic sorting device based on word recognition on a delivery note, comprising a conveyor for conveying logistics express and a recognition machine for recognizing the word on the delivery note of the logistics express, wherein two inverted U-shaped assembly plates are connected to the periphery of the conveyor, and a mounting plate is connected between the two assembly plates;

[0006] A plurality of vertical electric push rods are embedded in the top of the mounting plate, and the bottom ends of the moving parts of the plurality of vertical electric push rods are connected with inclined blocking plates for automatic sorting, the bottom ends of the blocking plates are connected with side baffles, the sides of the side baffles are connected with oblique connecting plates, an inclined material receiving plate is arranged above the oblique connecting plate, the bottom end of the material receiving plate is connected with a plurality of vertical support rods, the top end of the oblique connecting plate is provided with a plurality of circular channels for the vertical support rods to pass through, and a plurality of vertical pressure springs are connected between the material receiving plate and the oblique connecting plate.

[0007] As a preferred embodiment, the side baffle, the diagonal connecting plate and the material receiving plate are all located on one side of the conveyor, and the length of the material receiving plate is greater than the length of the diagonal connecting plate.

[0008] As a preferred embodiment, a protective plate is provided on the side of the side baffle close to the identification machine, and rubber plates for protecting logistics express are bonded to the side of the protective plate and the top of the receiving plate.

[0009] As a preferred embodiment, a plurality of transverse rods are connected to the side of the protection plate close to the side baffle, and a plurality of circular holes for the transverse rods to pass through are opened on the side of the side baffle.

[0010] As a preferred embodiment, a plurality of transverse pressure springs are connected between the protection plate and the side baffle.

[0011] As a preferred embodiment, a transverse support plate is installed at the top of the identification machine, and an auxiliary electric push rod is embedded in the top of the mounting plate.

[0012] As a preferred implementation scheme, the moving part of the auxiliary electric push rod is connected and fixed to the transverse support plate, and an infrared rangefinder is also installed at the bottom end of the transverse support plate.

[0013] As a preferred implementation scheme, side electric push rods are embedded on both sides of the assembly plate close to the identification machine, and the moving part of the side electric push rods is connected to an inclined baffle, and an infrared rangefinder is also installed on the side of the baffle.

[0014] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0015] The automatic sorting device based on the face sheet text recognition has the protective plate and the side baffle in an inclined state. During sorting, the conveyor does not need to stop or slow down. When it is necessary to unload materials at a designated position, the vertical electric push rod at the designated position is controlled to extend, so that the protective plate and the side baffle move down and are close to the conveyor. The express logistics moves along the conveyor, is blocked by the inclined protective plate, falls onto the inclined receiving plate, and then falls down.

[0016] The automatic sorting device based on the face sheet text recognition, when blocking, the logistics express impacts the protection plate, the rubber plate and the horizontal pressure spring can buffer the impact force, thereby protecting the logistics express; when receiving the materials, the logistics express falls onto the receiving plate, the rubber plate and the vertical pressure spring buffer the impact force of the fall, thereby also protecting the logistics express.

[0017] In the automatic sorting device based on face sheet text recognition, the infrared rangefinder of the inclined baffle can detect the position of the logistics express compared to the center line of the conveyor. By adjusting the side electric push rod, the position between the two inclined baffles is changed. The obstruction of the inclined baffle makes the transported logistics express as close to the center line of the conveyor as possible. After adjustment, the infrared rangefinder of the cross support plate can measure the height of the logistics express. By extending and retracting the auxiliary electric push rod, the height between the recognition machine and the logistics express is changed to better recognize the face sheet text of the logistics express.

[0018] The automatic sorting device based on the face sheet text recognition does not require the conveyor to stop or slow down during sorting, thereby ensuring the progress and efficiency of sorting. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0028] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0029] See also Figures 1 to 4 As shown, this embodiment includes a conveyor 1 for conveying logistics express and an identification machine 2 for identifying the text on the delivery note of the logistics express. The identification machine 2 is similar to a scanner gun for express delivery and belongs to the prior art. The logistics express is placed on the conveyor 1 manually or by using external conveying equipment, and is placed on the marking line as much as possible, with the delivery note of the logistics express facing upward. The center line of the outer periphery of the belt of the conveyor 1 is provided with a marking line belonging to the middle. The outer periphery of the conveyor 1 is connected to two inverted U-shaped assembly plates 3, and a mounting plate 4 is connected between the two assembly plates 3. A plurality of vertical electric push rods 5 are embedded in the top of the mounting plate 4, and the bottom ends of the moving parts of the plurality of vertical electric push rods 5 are connected to an inclined blocking plate 6 for automatic sorting. The angle of the blocking plate 6 relative to the direction of the conveyor 1 is selected according to actual needs to ensure that it falls quickly onto the receiving plate 9. The bottom end of the blocking plate 6 is connected to the side baffle 7. After the recognition machine 2 recognizes, the controller controls the vertical electric push rod 5 at the specified position to extend, so that the protection plate 12 and the side baffle 7 move down and approach the conveyor 1, and the logistics express moves along the conveyor 1.

[0030] The side of the side baffle plate 7 is connected to an oblique connecting plate 8, and an inclined material receiving plate 9 is arranged above the oblique connecting plate 8. The bottom end of the material receiving plate 9 is connected to a plurality of vertical support rods 10. The top of the oblique connecting plate 8 is provided with a plurality of circular channels for the vertical support rods 10 to pass through. The inner wall of the circular channel is bonded with an elastic rubber sleeve to play a damping function. A plurality of vertical pressure springs 11 are connected between the material receiving plate 9 and the oblique connecting plate 8. After the recognition machine 2 recognizes, the controller controls the vertical electric push rod 5 at the specified position to extend, so that the protection plate 12 and the side baffle plate 7 move down and approach to the conveyor 1. The logistics express moves along the conveyor 1, and after being blocked by the inclined protection plate 12, it falls on the inclined material receiving plate 9, and then falls. When receiving the material, the logistics express falls on the material receiving plate 9, and the rubber plate and the vertical pressure spring 11 buffer the impact force of the fall, which also plays a role in protecting the logistics express.

[0031] The side baffle 7 , the oblique connecting plate 8 and the material receiving plate 9 are all located at one side of the conveyor 1 , and the length of the material receiving plate 9 is greater than that of the oblique connecting plate 8 .

[0032] A protective plate 12 is provided on the side of the side baffle 7 close to the identification machine 2, and rubber plates for protecting express logistics are bonded to the side of the protective plate 12 and the top of the receiving plate 9. A plurality of transverse insertion rods 13 are connected to the side of the protective plate 12 close to the side baffle 7. A plurality of circular holes are opened on the side of the side baffle 7 for the transverse insertion rods 13 to pass through, and elastic rubber sleeves are bonded to the inner walls of the circular holes to play a damping function. A plurality of transverse pressure springs 14 are connected between the protective plate 12 and the side baffle 7. When blocking, the express logistics impacts the protective plate 12, and the rubber plate and the transverse pressure spring 14 can buffer the impact force, thereby protecting the express logistics.

[0033] A transverse support plate 15 is installed at the top of the recognition machine 2, and an auxiliary electric push rod 16 is embedded in the top of the mounting plate 4. The moving part of the auxiliary electric push rod 16 is connected and fixed to the transverse support plate 15, and an infrared rangefinder 17 is also installed at the bottom of the transverse support plate 15. Side electric push rods 18 are embedded on both sides of the assembly plate 3 close to the recognition machine 2. The moving part of the side electric push rod 18 is connected with an inclined oblique baffle 19, and an infrared rangefinder 17 is also installed on the side of the oblique baffle 19. The infrared rangefinder 17 of the oblique baffle can detect the position of the logistics express compared with the center line of the conveyor 1. By adjusting the side electric push rod 18, the position between the two oblique baffles 19 is changed. After being blocked by the oblique baffle 19, the transported logistics express is as close to the center line of the conveyor 1 as possible. After adjustment, the infrared rangefinder 17 of the transverse support plate 15 can measure the height of the logistics express. The auxiliary electric push rod 16 is extended and retracted to change the height of the recognition machine 2 and the logistics express, so as to better identify the text on the logistics express delivery sheet.

[0034] The conveyor 1, the identification machine 2, the vertical electric push rod 5, the auxiliary electric push rod 16, the infrared rangefinder 17 and the side electric push rod 18 are all conventional instruments. Their working principles, sizes and models are irrelevant to the problems solved by this application, so they will not be described in detail. The control method of the utility model is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0035] How it works

[0036] The automatic sorting device based on the face sheet text recognition can place the logistics express on the conveyor 1 manually or by using external conveying equipment. The infrared rangefinder 17 of the inclined baffle can detect the position of the logistics express compared to the center line of the conveyor 1. By adjusting the side electric push rod 18, the position between the two inclined baffles 19 is changed. After the obstruction of the inclined baffle 19, the transported logistics express is placed at the center line of the conveyor 1 as much as possible. After adjustment, the infrared rangefinder 17 of the horizontal support plate 15 can measure the height of the logistics express. The auxiliary electric push rod 16 is extended and retracted to change the height of the recognition machine 2 and the logistics express, so as to better recognize the face sheet text of the logistics express.

[0037] After the recognition machine 2 recognizes, the controller controls the vertical electric push rod 5 at the specified position to extend, so that the protection plate 12 and the side baffle 7 move down and approach the conveyor 1. The logistics express moves along the conveyor 1, and after being blocked by the inclined protection plate 12, it falls on the inclined receiving plate 9, and then falls. When blocked, the logistics express hits the protection plate 12, and the rubber plate and the horizontal pressure spring 14 can buffer the impact force, which plays a role in protecting the logistics express. When receiving the material, the logistics express falls on the receiving plate 9, and the rubber plate and the vertical pressure spring 11 buffer the impact force of the fall, which also plays a role in protecting the logistics express.
