TECHNICAL FIELD
[0001] The utility model relates to a kind of feeding equipment for assembly line printer, especially the wide range of assembly line printing automatic feeding machine. BACKGROUND
[0002] When producing accessories or fittings for clothing, luggage and the like, the basic material is generally first injection molded according to the required accessories or fittings, and the injection molded basic material includes the front and back. For flat accessories or fittings, the front and back are both flat, but the flatness of the front is higher than that of the back. For some three-dimensional accessories or fittings such as bears, the front is a concave-convex surface, and the back is a flat surface. The front and back of the just-injection molded basic material are both without any pattern or figure, so it is necessary to use an assembly line printing device to print the required pattern or figure on the front of the basic material of the accessories or fittings. The common assembly line printing device currently comprises a printing conveyor belt, a camera and a print head. The assembly line printing device mainly detects the position and angle of the conveyed basic material through the camera, and adjusts the position and angle of the print head according to the detected position and angle of the basic material, so that the print head can accurately cooperate with the position of the basic material to be printed to perform printing work on the basic material. Before the assembly line printing device performs specific printing work, the basic material needs to be conveyed to the printing conveyor belt in a manner with the front facing upwards.
[0003] The common material feeding method of the assembly line printing device currently mainly includes manual feeding and vibration disc combined with conveyor belt feeding. The manual feeding needs to ensure that the basic material is with the front facing upwards and needs to arrange the basic material, so the overall work efficiency is low. Although the vibration disc combined with conveyor belt feeding can improve the work efficiency compared with the manual feeding method, the vibration disc can select the direction of feeding due to the characteristics of the vibration disc, and the automatic feeding method combined with the conveyor belt can improve the work efficiency. However, because the width of the vibration disc feeding track is fixed, the vibration disc can only perform the directional feeding work on the basic material of a specific size. Once the size of the basic material to be printed changes, the vibration disc cannot perform the directional work, and even cannot convey the basic material to the conveyor belt, which causes the subsequent assembly line printing device to be unable to perform the printing work, and the overall applicability is low. Therefore, how to design a feeding device for assembly line printing that can be applied to the feeding work of basic materials of different sizes and with concave-convex surfaces, and can ensure the work efficiency is a problem to be solved at present.

[0029] Working principle: in the specific work of loading, first connect the entire device to the external safety power, so that the visual sensor 5, controller 7, encoder 29 power on (the visual sensor 5 used in the utility model is a camera, the specific model is MV-CU013-A0GC; the controller 7 can specifically adopt AFMC_V1.3, FX2C-20MRD or Cortex-R8 etc. model; the encoder 29 used in the application is an incremental optical rotary encoder, which can specifically adopt ZSP3806 etc. model); then pour the material that needs to be printed into the feeding bin 2, complete the preparation; then control the lifting motor to start, the lifting motor will drive the lifting driving shaft to rotate after starting, the lifting driving shaft will drive the lifting conveyor belt 31 to move after rotating, the lifting conveyor belt 31 will drive the lifting driven shaft to rotate in the process of moving, so that the lifting conveyor belt 31 moves circularly; because the whole lifting conveyor belt 31 is arranged in an inclined manner, plus the lifting conveyor belt 31 is provided with a plurality of uniformly distributed partitions 32, and one end of the lifting conveyor belt 31 is arranged in the feeding bin 2, so that when the lifting conveyor belt 31 drives the partition 32 to move upward together, the partition 32 will lift the material in the feeding bin 2 and move to the space between the partition 32 and the lifting conveyor belt 31, realizing the lifting of the material; with the continuous upward movement of the lifting conveyor belt 31, the material will be moved above the receiving hopper 33, at this time, with the continuous movement of the lifting conveyor belt 31, the lifting conveyor belt 31 will change from upward movement to downward movement, so that the material between the partition 32 and the lifting conveyor belt 31 is poured into the receiving hopper 33, and the material will flow to the first conveyor belt 23 through the discharge channel on the receiving hopper 33, completing the material moving work.
[0030] When the material is transported to the first conveying belt 23, the driving motor connected with the first conveying belt 23 and the second conveying belt 24 is started to drive the corresponding driving shaft to rotate, and the different driving shafts rotate to drive the first conveying belt 23 and the second conveying belt 24 to rotate, and the first conveying belt 23 and the second conveying belt 24 rotate to drive the corresponding driven shaft to rotate, so that the first conveying belt 23 and the second conveying belt 24 can move in a cycle; with the movement of the first conveying belt 23, the first conveying belt 23 drives the material falling on the first conveying belt 23 to move to the direction of the guide piece 25, when the material moves to the position of the guide piece 25, because the guide piece 25 is arranged in an inclined shape and the two ends are arranged on the first conveying belt 23 and the second conveying belt 24 respectively; when the material contacts with the guide piece 25, the material entering the side of the guide piece 25 close to the second conveying belt 24 will translate to the direction of the second conveying belt 24 under the action of the guide piece 25, and finally move from the first conveying belt 23 to the second conveying belt 24 (i.e. from the output end of the first conveying belt 23 to the input end of the second conveying belt 24), and because the feeding bin 2 is arranged directly below the output end of the first conveying belt 23, part of the material moving to the side of the guide piece 25 away from the second conveying belt 24 will return to the feeding bin 2 along the first conveying belt 23 to be recharged.
[0031] When the material is moved to the second conveying belt 24 under the action of the guide 25, the moving second conveying belt 24 moves the material to the direction of the blocking piece 3. Under the mutual cooperation of the guiding action of the blocking piece 3 and the conveying action of the second conveying belt 24, the material moves to the discharging position of the blocking piece 3. Because only a gap between a single material width and two material widths is provided between the discharging position of the blocking piece 3 and the edge of the second conveying belt 24, only a single row of material can pass through the gap. When multiple rows of material pass through the gap, the material exceeding the single row is pushed to the first conveying belt 23 on one side to perform the re-feeding and orientation work. At the same time, when the single row of material passes through the discharging position of the blocking piece 3, the height limiting piece 4 above the discharging position blocks the material accumulated above, so that the material passes through the discharging position of the blocking piece 3 one by one and moves to the direction of the vision sensor 5. When the height limiting piece 4 works, the first motor 22 is started to drive the height limiting piece 4 to rotate. In addition, the surface of the height limiting piece 4 in contact with the material is a brush piece, so that the rotating height limiting piece 4 can push the material above to move to one side. In addition, the direction of the rotation of the first motor 22 is limited, so that the rotation of the height limiting piece 4 can rotate to separate the material from the second conveying belt 24 to the first conveying belt 23 to perform the re-feeding and orientation work. Under the cooperation of the blocking piece 3 and the height limiting piece 4, the material is moved to the vision sensor 5 one by one to determine the front and back surface orientations of the material, so that the phenomenon of the determination error of the front and back surface orientations of the material caused by the multiple rows of material passing through the vision sensor at the same time or the multiple materials passing through the vision sensor in a stacked manner is avoided, and the accuracy of the subsequent orientation work is ensured.
[0032] When the single material passes through the blocking piece 3, it moves to the position directly below the vision sensor 5 along the second conveying belt 24. When the material passes through the position directly below the vision sensor 5, the vision sensor 5 photographs the top surface of the material and transmits the photographed image to the external controller 7. After receiving the photographed image data, the controller 7 determines the image according to the internally set image determination formula to determine whether the passed material is the front surface up or the back surface up (the front surface of the material has different protrusions or the back surface of the material has a flat surface). If the passed material is the front surface up, the controller 7 does not control the first air nozzle 6 to start, so that the material directly passes through the first air nozzle 6 after passing through the vision sensor 5 and moves to the output end of the second conveying belt 24 and then moves to the next station. When the material is the back surface up and passes through the vision sensor 5, the controller controls the first air nozzle 6 to start for a certain time (just the distance from the vision sensor 5 to the position directly opposite the first air nozzle 6) to blow the material from the second conveying belt 24 to the first conveying belt 23 by the first air nozzle 6 to perform the re-feeding and orientation work. The orientation work of the material is completed.
[0033] When the height or width of the material to be selected changes, the distance between the bottom surface of the height limiting piece 4 and the top surface of the second conveying belt 24 needs to be adjusted, or the distance between the material blocking piece 3 and the edge of the second conveying belt 24 needs to be adjusted; when the distance between the bottom surface of the height limiting piece 4 and the top surface of the second conveying belt 24 is adjusted, only the first servo motor 14 needs to be started by control, and after the first servo motor 14 is started, it will drive the first ball screw 15 to rotate, and after the first ball screw 15 rotates, it will drive the first lifting seat to move up or down, and in the process of moving up or down, the first lifting seat will drive the height limiting piece 4 and the first motor 22 to move up and down together, so as to adapt to the passing of single materials of different heights; when the distance between the material blocking piece 3 and the edge of the second conveying belt 24 is adjusted, the adjusting servo motor 12 is controlled to start, and after the adjusting servo motor 12 is started, it will drive the adjusting ball screw 13 to rotate, and after the adjusting ball screw 13 rotates, it will drive the adjusting seat to move along the horizontal direction perpendicular to the moving direction of the second conveying belt 24, and in the process of moving, the adjusting seat will drive the material blocking piece 3 to move together, so as to adjust the distance between the material blocking piece 3 and the edge of the second conveying belt 24.
[0034] When the material selected by the material selection work is moved to the inlet end of the guide frame along the second conveying belt 24 and is fed into the guide frame, the corresponding second air nozzle 8 is controlled to start, and the material is blown to one side by the second air nozzle 8, and the position of the guide frame corresponding to the upper rack 1 is an inclined surface, so that the material can automatically slide to the discharge position of the guide frame (i.e. moving along the inclined blocking piece 26 to the vertical blocking piece 27); in order to make the second air nozzle 8 blow the material into the guide frame in a discrete manner, the time of starting the second air nozzle 8 or the flow of blowing gas needs to be controlled according to the number of materials entering or the number of times the second air nozzle 8 is started, so as to realize the distance of the material blown by the second air nozzle 8 moving away from the second air nozzle 8, and the different time of starting the second air nozzle 8 or the flow of blowing gas each time can control the different distance of the material blown by the second air nozzle 8, so that the material can move to the discharge position of the guide frame (i.e. between the two vertical blocking pieces 27) in a discrete manner and be arranged and stored.
[0035] During the whole process, because the second air nozzle 8 in the device is provided with two and is respectively arranged at the two sides of the feeding position of the guide frame (for the convenience of subsequent description, the second air nozzle A and the second air nozzle B are used for differentiation), during the specific discrete blowing process, only one second air nozzle 8 of the second air nozzle A and the second air nozzle B is in working state each time, the two can adopt the alternating working mode (that is, the second air nozzle A blows first, then the second air nozzle B blows, and then the second air nozzle A blows), or the mode that the second air nozzle A blows several times and then the second air nozzle B blows the same number of times, and then the second air nozzle A blows the same number of times; at the same time, the blowing flow or blowing time of the same second air nozzle 8 each time also presents a ladder type increase or decrease; because the guide frame is provided with the baffle 10, the gap only for a single material to pass between the baffle 10 and the guide frame, the baffle can block the material during the process that the material is discretely blown into the guide frame and slides to the discharging position of the guide frame, so as to avoid the phenomenon that the material is turned over during the process; when the material height and the like needs to be changed, the second servo motor 16 can be controlled to start, after the second servo motor 16 starts, the second ball screw 17 will be driven to rotate, after the second ball screw 17 rotates, the second lifting seat will be driven to move along the direction perpendicular to the top surface of the rack 1, and the baffle 10 is installed on the second lifting seat, during the movement of the second lifting seat, the baffle 10 will be driven to move together, so as to adjust the distance between the bottom surface of the baffle 10 and the inner bottom surface of the guide frame, so as to adapt to the discrete feeding work of the materials with different heights.
[0036] When the materials arranged in discrete are arranged neatly between the two vertical stop pieces 27, the front row of materials will be in contact with the feeding roller 9. At this time, the feeding motor 18 is controlled to start, which will drive the feeding roller 9 to rotate. The rotation of the feeding roller 9 will drive the surface brush piece 19 to rotate. The distance between each adjacent two brush pieces 19 is only a gap for single row of materials to pass through, so that the brush piece 19 first in contact with the materials during the rotation of the feeding roller 9 will push the front row of materials to move to the space between the feeding roller 9 and the rack 1, and finally push to the feeding end of the third conveying belt 28. At the same time, the rear brush piece 19 will block the rear row of materials to avoid the rear row of materials moving to the third conveying belt 28 with the front row of materials, realizing the feeding of single row of materials each time the feeding roller 9 rotates. When the single row of materials is conveyed to the third conveying belt 28, the third motor is controlled to start for a certain time. The third motor will drive the third driving shaft to rotate after starting, which will drive the third conveying belt 28 to move to the printing area of the flow printing device. The third conveying belt 28 will drive the third driven shaft to rotate during the movement. Under the cooperation of the rotating third driving shaft and the third driven shaft, the third conveying belt 28 can move in a loop. The encoder 29 for detecting the conveying state of the third conveying belt 28 will detect the conveying state of the third conveying belt 28 synchronously during the movement of the third conveying belt 28. When the third conveying belt 28 stops, the encoder 29 can send the detected data such as the moving distance, moving time and start-stop state of the third conveying belt 28 to the controller 7. The controller 7 controls the start time of the feeding motor 18 according to the received data information, and then controls the rotation angle of the feeding roller 9, so that the feeding speed of the feeding roller 9 and the feeding speed of the third conveying belt 28 are matched, and the phenomenon of material accumulation on the third conveying belt 28 does not occur, ensuring the stability of the work, and making the rotation of the feeding roller 9 well cooperate with the movement of the third conveying belt 28, without manual adjustment, which is convenient for use and improves the flexibility of use. The whole feeding work is completed.
