[0029] Facing a huge number of mails, if the information entry and recognition work is processed manually, it will require a large amount of human resources and is prone to errors.

[0030] The following is a preferred embodiment of a flat material sorting device provided by the present invention that can solve the above technical problems.

[0031] The preferred embodiment of the present invention provides a flat material sorting device. Please refer to Figure 1 and Figure 2 , the flat material sorting device includes a frame 1, a feeding device 2, an identification and sorting device 3 and a manipulator 4. The feeding device 2 is arranged on the frame 1, and the feeding device 2 includes a feeding transmission structure 21 for horizontally conveying the flat material 100 (see Figure 6 ).

[0032] The identification and sorting device 3 is arranged on the frame 1 and is located on the lateral side of the material feeding device 2. The identification and sorting device 3 includes a sorting transmission structure 31, an information entry scanning gun 32, an OK receiving bin 33, an NG receiving bin 34, and a sorting pushing structure 35. The sorting transmission structure 31 is used to convey the flat material 100 placed flat in the lateral direction. The feeding end of the sorting transmission structure 31 is adjacent to the discharging end of the material feeding transmission structure 21. The information entry scanning gun 32 is arranged facing the sorting transmission structure 31 and is used to scan and enter the information of the flat material 100. Both the OK receiving bin 33 and the NG receiving bin 34 are arranged at the discharging end of the sorting transmission structure 31. The OK receiving bin 33 is used to collect the normal flat materials 100, and the NG receiving bin 34 is used to collect the abnormal flat materials 100. The sorting pushing structure 35 is arranged at the discharging end of the sorting transmission structure 31 and is used to push the flat material 100 from the sorting transmission structure 31 into the OK receiving bin 33 or the NG receiving bin 34. The manipulator 4 is arranged on the frame 1 and is used to convey the flat material 100 from the discharging end of the material feeding transmission structure 21 to the feeding end of the sorting transmission structure 31.

[0033] In each figure, the x-direction is the lateral direction and the y-direction is the longitudinal direction.

[0034] When the flat material sorting equipment of the present invention is working, a stack of flat materials 100 is placed at the feeding end of the material feeding transmission structure 21. The material feeding transmission structure 21 conveys the flat materials 100 in the lateral direction. The manipulator 4 places the flat materials 100 at the discharging end of the material feeding transmission structure 21 one by one at the feeding end of the sorting transmission structure 31. During the process of the sorting transmission structure 31 conveying the flat materials 100 in the lateral direction, the information entry scanning gun 32 scans and enters the information of the flat materials 100. When the flat materials 100 reach the discharging end of the sorting transmission structure 31, the normal flat materials 100 (flat materials 100 whose information can be entered and discriminated) can enter the OK receiving bin 33, and the abnormal flat materials 100 (flat materials 100 whose information cannot be entered and discriminated) can enter the NG receiving bin 34. Taking the OK receiving bin 33 being located on the longitudinal side of the sorting transmission structure 31 and the NG receiving bin 34 being located on the lateral side of the sorting transmission structure 31 as an example, the sorting pushing structure 35 can push the normal flat materials 100 in the longitudinal direction into the OK receiving bin 33, and the abnormal flat materials 100 continue to move forward and fall into the NG receiving bin 34. It should be noted that the positions of the OK receiving bin 33 and the NG receiving bin 34 can be adjusted according to actual needs. For example, the OK receiving bin 33 is located on the lateral side of the sorting transmission structure 31 and the NG receiving bin 34 is located on the longitudinal side of the sorting transmission structure 31. The flat material sorting equipment of the present invention can automatically identify and sort the flat materials 100, effectively saving manpower and improving the sorting accuracy. The flat materials 100 can be mails or other materials such as document bags, envelopes, etc.

[0035] Please refer to Figure 1 and Figure 3 , the manipulator 4 includes a material-gripping suction cup 41 and a driving assembly. The driving assembly is arranged on the frame 1 and connected to the material-gripping suction cup 41, and is used to drive the material-gripping suction cup 41 to convey the flat material 100 from the discharging end of the material-feeding transmission structure 21 to the loading end of the sorting transmission structure 31. By conveying the flat material 100 through the material-gripping suction cup 41, damage to the flat material 100 can be avoided and the flat material 100 can be prevented from deforming.

[0036] Please also refer to Figure 6 , optionally, the driving assembly includes a rotary toggle 46 and a driving motor. After the material-gripping suction cup 41 adsorbs the flat material 100 located on the material-feeding transmission structure 21, the driving motor drives the material-gripping suction cup 41 to turn over, so that the flat material 100 is located between the material-gripping suction cup 41 and the sorting transmission structure 31, and then the material-gripping suction cup 41 releases the flat material 100 to complete the conveyance of the flat material 100. In other embodiments, the driving method and path can be flexibly adjusted. For example, by means of translation combined with lifting, etc., the material-gripping suction cup 41 is driven to convey the flat material 100 from the discharging end of the material-feeding transmission structure 21 to the loading end of the sorting transmission structure 31.

[0037] The material-feeding device further includes two width adjustment plates 27 and a width adjustment screw rod 28. The two width adjustment plates 27 are respectively arranged on the longitudinal two sides of the material-feeding transmission structure 21, and the two width adjustment plates 27 cooperate to longitudinally limit the flat material 100 on the material-feeding transmission structure 21. The two width adjustment plates 27 are longitudinally adjustable to adapt to flat materials 100 of different sizes. The width adjustment screw rod 28 is connected to the two width adjustment plates 27 to adjust the longitudinal movement of the two width adjustment plates 27. In other embodiments, cylinders or other components can also be used to adjust the longitudinal movement of the two width adjustment plates 27.

[0038] Please refer to Figure 3, the manipulator 4 further includes a vacuum pump 42, a vacuum pipeline control solenoid valve 43, an air compressor 44, and a compressed air control solenoid valve 45. The vacuum pump 42 is connected to the material gripping suction cup 41 through a pipeline and is used to make the material gripping suction cup 41 generate suction force to be able to adsorb the flat material 100. The vacuum pipeline control solenoid valve 43 is connected between the vacuum pump 42 and the material gripping suction cup 41 and is used to control the on and off of the pipeline between the vacuum pump 42 and the material gripping suction cup 41. The air compressor 44 is connected to the material gripping suction cup 41 through a pipeline and is used to introduce compressed air into the material gripping suction cup 41 to release the flat material 100. The compressed air control solenoid valve 45 is connected between the air compressor 44 and the material gripping suction cup 41 and is used to control the on and off of the pipeline between the air compressor 44 and the material gripping suction cup 41. If the material gripping suction cup 41 only releases the flat material 100 by cutting off the vacuum, since the material gripping suction cup 41 mostly uses rubber material, the rate of breaking the vacuum between the material gripping suction cup 41 and the flat material 100 is relatively slow. With the above structure, when the device needs to vacuum-adsorb the flat material 100, the vacuum pipeline control solenoid valve 43 is opened, the compressed air control solenoid valve 45 is closed, and the vacuum generated by the vacuum pump 42 makes the material gripping suction cup 41 generate suction force to be able to adsorb the flat material 100, so as to realize the handling and transfer of the flat material 100. When the flat material 100 reaches the release position, the vacuum pipeline control solenoid valve 43 is closed to cut off the vacuum pipeline, the vacuum pipeline control solenoid valve 43 is closed, the compressed air control solenoid valve 45 is opened, the compressed air in the air compressor 44 is introduced into the material gripping suction cup 41 to break the vacuum, and after completion, the compressed air control solenoid valve 45 is closed, and the cycle is repeated in turn to achieve the purpose of quickly loading the flat material 100.

[0039] Please refer to Figure 4, the material feeding device 2 further includes an inclined plate 22, a plurality of height stoppers 23 and a plurality of width stoppers 24. The inclined plate 22 is inclinedly arranged at the discharging end of the material feeding transmission structure 21, and one end of the inclined plate 22 away from the discharging end of the material feeding transmission structure 21 inclines downward. Height stoppers 23 are arranged at the bottom end of the inclined plate 22 and at the upper oblique side of the inclined plate 22 biased towards the identification and sorting device 3. The plurality of height stoppers 23 are used to block the top and bottom of the flat material 100. Width stoppers 24 are arranged at the longitudinal two sides of the bottom end of the inclined plate 22. The plurality of width stoppers 24 are used to block the two side edges of the flat material 100. The flat material 100 is conveyed onto the inclined plate 22, and the plurality of height stoppers 23 and the plurality of width stoppers 24 are used to limit the flat material 100, so that the inclined plate 22 can store an appropriate amount of flat materials 100. Relying on the gravity of this part of the appropriate amount of flat materials 100, the flat materials 100 on the inclined plate 22 are naturally close and moderate, ensuring that during the vacuum grasping process of the material grasping suction cup 41, the flat materials 100 will not be difficult to separate due to too much pressure, nor will the situation of the material grasping suction cup 41 breaking the vacuum occur because the flat materials 100 are not close enough to each other.

[0040] Please refer to Figure 4 , ball bearings are arranged on the inner sides of the height stoppers 23 and the width stoppers 24, which can ensure that the flat material 100 can be more smoothly separated from the height stoppers 23 and the width stoppers 24 during the process of the material grasping suction cup 41 sucking the material.

[0041] The height of the bottom end of the inclined plate 22 is adjustable. The plurality of height stoppers 23 and the plurality of width stoppers 24 are all movably arranged to adapt to flat materials 100 of different sizes. When the size of the flat material 100 is small, adjusting the bottom end of the inclined plate 22 to a lower position can make the flat materials 100 closer. The plurality of height stoppers 23 and the plurality of width stoppers 24 are adjusted to appropriate positions to match the size of the small-sized flat material 100. When the size of the flat material 100 is large, adjusting the bottom end of the inclined plate 22 to a higher position can prevent the flat materials 100 at the bottom from bearing too much pressure. The plurality of height stoppers 23 and the plurality of width stoppers 24 are adjusted to appropriate positions to match the size of the large-sized flat material 100. With the above structure, it is convenient to convey flat materials 100 of different sizes.

[0042] Please refer to Figure 4, the material feeding device 2 further includes a counterweight 25, which is placed on the material feeding transmission structure 21 and advances driven by the material feeding transmission structure 21 for limiting the vertical flat material 100 from the rear. The counterweight 25 is placed on the material feeding transmission structure 21 and is driven to advance by the friction force with the material feeding transmission structure 21, ensuring tight feeding between the vertical flat materials 100 and preventing interruption or collapse of the supply of the flat material 100. Since the counterweight 25 provides the power to press the flat material 100 forward by friction force and there is no rigid screw locking connection, etc., during the feeding process, only need to manually move the counterweight 25 backward, which is convenient and fast.

[0043] Please refer to Figure 4 , the material feeding device 2 further includes a movable stopper 26, which is movably arranged on the frame 1 and is located at the bottom end of the inclined plate 22 for cooperating with the upper height stopper 23 to limit the counterweight 25. When the number of the flat materials 100 is small, the counterweight 25 will also move to the inclined plate 22 along with the decreasing flat materials 100. When the last flat material 100 is distributed, the counterweight 25 is first blocked by the bottom height stopper 23 to prevent falling. Since the blocking height of the bottom height stopper 23 is limited, in order to prevent accidents, the movable stopper 26 moves upward to effectively block the counterweight 25 safely. During normal operation, the movable stopper 26 is located below the inclined plate 22 and does not affect the manipulator 4 from grasping the flat material 100.

[0044] A channel is arranged above the sorting transmission structure 31. After the driving motor drives the material grasping suction cup 41 to turn over, the flat material 100 is located between the material grasping suction cup 41 and the channel. The material grasping suction cup 41 breaks the vacuum, and the flat material 100 falls into the channel, which is convenient for the subsequent transportation and sorting of the flat material 100 in the channel. In this example, the height of the inclined plate 22 is higher than that of the channel to better match the form of transporting the flat material 100 by turning over the material grasping suction cup 41. In addition, in order to match flat materials 100 of different sizes, the number of channels can be at least two, and different channels are used to assist in transporting flat materials 100 of different sizes.

[0045] Please refer to Figure 5, above the sorting transmission structure 31, a first channel 36 and a second channel 37 are provided. The longitudinal dimension of the first channel 36 is greater than that of the second channel 37, and the first channel 36 is located above the second channel 37. The second channel 37 communicates with the first channel 36. At the connection between the second channel 37 and the first channel 36, the vertical projection of the second channel 37 is located within the vertical projection of the first channel 36. If the flat material 100 is of large size, it can fall into the first channel 36, and the first channel 36 can limit the longitudinal two sides of the large-size flat material 100 to prevent the flat material 100 from moving longitudinally. If the flat material 100 is of small size, it will pass through the first channel 36 and fall into the second channel 37. The second channel 37 can limit the longitudinal two sides of the small-size flat material 100 to prevent the flat material 100 from moving longitudinally.

[0046] An outlet is provided on the longitudinal side of the second channel 37, and the outlet is located at the discharging end of the sorting transmission structure 31. Tooth pins 311 are provided on the sorting transmission structure 31. The identification and sorting device 3 further includes a positioning brush 39, which is arranged above the sorting transmission structure 31 and is used to cooperate with the tooth pins 311 to laterally position the material located in the second channel 37. The distance between adjacent tooth pins 311 in the lateral direction has a large gap with the lateral dimension of the small-size flat material 100. Therefore, during the process of the sorting transmission structure 31 transporting the small-size flat material 100 in the lateral direction, the small-size flat material 100 is prone to lateral movement, and the deviation angle between the small-size flat material 100 and the second channel 37 is relatively large, resulting in a relatively large inclination angle of the small-size flat material 100 at the outlet, which is likely to cause frequent jamming of the small-size flat material 100 at the outlet. With the above structure, when the small-size flat material 100 is transported to the discharging end of the sorting transmission structure 31, the positioning brush 39 first blocks the small-size flat material 100 below the positioning brush 39, playing a role in adjusting the inclination angle of the small-size flat material 100. At this time, the resistance of the positioning brush 39 is greater than the friction between the flat material 100 and the sorting transmission structure 31, and the small-size flat material 100 will not move forward. When the rear tooth pin 311 contacts the small-size flat material 100, the thrust of the tooth pin 311 plus the friction of the sorting transmission structure 31 is greater than the resistance of the positioning brush 39, and the small-size flat material 100 moves forward. During the moving process, the positioning brush 39 and the tooth pins 311 cooperate to further adjust the inclination angle of the small-size flat material 100 to ensure the correct attitude of the small-size flat material 100, so that the small-size flat material 100 can leave the outlet in a straight and correct attitude, thereby reducing the risk of jamming.

[0047] The outlet also communicates with the first channel 36 for the output of the large-size flat material 100. The output of the large-size flat material 100 can be similar to that of the small-size flat material 100 and will not be elaborated here.

[0048] Please refer to Figure 2 and Figure 5 , one of the OK receiving box 33 and the NG receiving box 34 is located on the lateral side of the sorting transmission structure 31, and the other is located on the longitudinal side of the sorting transmission structure 31. The identification and sorting device 3 also includes a material blocking member 38, which is vertically movably arranged above the unloading end of the sorting transmission structure 31. When the material blocking member 38 is in a raised state, the flat material 100 can be output in the lateral direction, and when the material blocking member 38 is in a lowered state, the flat material 100 can be output in the longitudinal direction. Take the OK receiving box 33 located on the longitudinal side of the sorting transmission structure 31 and the NG receiving box 34 located on the lateral side of the sorting transmission structure 31 as an example. If the information input barcode scanning gun 32 identifies the flat material 100 as a normal flat material 100, the material blocking member 38 moves downward to block the normal flat material 100 in advance. The sorting push structure 35 pushes the normal flat material 100 into the OK receiving box 33, and in this process, the material blocking member 38 can guide the normal flat material 100. If an abnormal flat material 100 appears, the material blocking member 38 is raised, and the abnormal flat material 100 is conveyed to the NG receiving box 34 by the sorting transmission structure 31. Since the equipment requires extremely high efficiency, the material blocking member 38 can be driven by a motor.

[0049] The working principle of the flat material sorting device of the preferred embodiment of the present invention is as follows: A stack of flat materials 100 is placed vertically at the feeding end of the material discharging transmission structure 21, and a counterweight block 25 is placed on the material discharging transmission structure 21 to support the flat materials 100 behind. The material discharging transmission structure 21 transmits the flat materials 100 and the counterweight block 25 in the horizontal direction. The flat materials 100 are conveyed to the inclined plate 22, and the flat materials 100 are limited by a plurality of height stops 23 and a plurality of width stops 24, so that the inclined plate 22 can store an appropriate amount of flat materials 100.

[0050] The manipulator 4 places the flat materials 100 on the inclined plate 22 one by one to the feeding end of the sorting transmission structure 31. When the equipment needs to vacuum absorb the flat materials 100, the vacuum pipeline control solenoid valve 43 is opened, and the compressed air control solenoid valve 45 is closed. The vacuum generated by the vacuum pump 42 enables the material grabbing suction cup 41 to generate suction to absorb the flat materials 100, thereby realizing the transportation and transfer of the flat materials 100. When the flat materials 100 reach the release position, the vacuum pipeline control solenoid valve 43 is closed, the vacuum pipeline is cut off, the vacuum pipeline control solenoid valve 43 is closed, the compressed air control solenoid valve 45 is opened, and the compressed air in the air compressor 44 is introduced into the material grabbing suction cup 41 to break the vacuum. After completion, the compressed air control solenoid valve 45 is closed, and the cycle is repeated in sequence to achieve the purpose of fast feeding of flat materials 100.

[0051] If the flat material 100 is of large size, it can be conveyed through the first channel 36, and the first channel 36 can limit the longitudinal two sides of the large-size flat material 100 to prevent the flat material 100 from moving longitudinally. If the flat material 100 is of small size, it can be conveyed through the second channel 37, and the second channel 37 can limit the longitudinal two sides of the small-size flat material 100 to prevent the flat material 100 from moving longitudinally.

[0052] During the process of the sorting transmission structure 31 conveying the flat material 100 horizontally, the information entry barcode scanner 32 scans the flat material 100 to enter information.

[0053] When the small-size flat material 100 is conveyed to the discharging end of the sorting transmission structure 31, the positioning brush 39 first blocks the small-size flat material 100 below the positioning brush 39 to adjust the inclination angle of the small-size flat material 100. At this time, the resistance of the positioning brush 39 is greater than the friction force of the sorting transmission structure 31, and the small-size flat material 100 will not move forward. When the rear tooth nails 311 contact the small-size flat material 100, the thrust of the tooth nails 311 plus the friction force of the sorting transmission structure 31 is greater than the resistance of the positioning brush 39, and the small-size flat material 100 moves forward. During the moving process, the positioning brush 39 and the tooth nails 311 cooperate to further adjust the inclination angle of the small-size flat material 100 to ensure that the small-size flat material 100 has a correct posture, so that the small-size flat material 100 can leave the discharge port in a straight and correct posture, thereby reducing the risk of material jamming.

[0054] If the information entry barcode scanner 32 identifies that the flat material 100 is a normal flat material 100, the material blocking member 38 moves downward to block the normal flat material 100 in advance. The sorting and pushing structure 35 pushes the normal flat material 100 into the OK receiving box 33. During this process, the material blocking member 38 can play a guiding role for the normal flat material 100. If an abnormal flat material 100 appears, the material blocking member 38 rises, and the sorting transmission structure 31 conveys the abnormal flat material 100 into the NG receiving box 34.

[0055] In this way, the working process of the flat material sorting device of the present preferred embodiment is completed.

[0056] For the flat material sorting equipment of the present invention, during operation, a stack of flat materials is placed at the feeding end of the feeding transmission structure. The feeding transmission structure conveys the flat materials horizontally. The manipulator places the flat materials at the discharging end of the feeding transmission structure one by one onto the feeding end of the sorting transmission structure. During the process of the sorting transmission structure conveying the flat materials horizontally, the information entry barcode scanner scans the flat materials to enter information. When the flat materials reach the discharging end of the sorting transmission structure, normal flat materials (flat materials whose information can be entered and discriminated) can enter the OK receiving box, and abnormal flat materials (flat materials whose information cannot be entered and discriminated) can enter the NG receiving box. Taking the OK receiving box being located on the longitudinal side of the sorting transmission structure and the NG receiving box being located on the transverse side of the sorting transmission structure as an example, the sorting pushing structure can push the normal flat materials longitudinally into the OK receiving box, and the abnormal flat materials continue to move forward and fall into the NG receiving box. The flat material sorting equipment of the present invention can automatically identify and sort flat materials, effectively saving manpower and improving the accuracy of sorting. The flat materials can be mails or other materials.

[0057] In summary, although the present invention has been disclosed above with preferred embodiments, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the concept of the technical solution of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
