Detailed implementation manners

[0040] The following further describes the present invention with specific embodiments. Refer to Figure 1 —17:

[0041] In the present invention, the front-back direction refers to the conveying direction of the material mass and tableware along the production line.

[0042] A tableware production line includes a feeding and arranging machine 1, a press 2, a discharging machine 3, a flipping and spraying machine 4, and a baking line 5 arranged in sequence; the feeding and arranging machine 1 includes a feeding conveyor belt mechanism 6, a receiving tray mechanism 7, a arranging manipulator 9 for transferring the material mass 8 on the feeding conveyor belt mechanism 6 to the receiving tray mechanism 7, and a feeding manipulator 10 for transferring the material mass 8 on the receiving tray mechanism 7 to the press 2; the press 2 includes a forming mold 11 for tableware, and the material mass 8 is heated and foamed into shape through the forming mold 11; the feeding manipulator 10 transfers the material mass 8 to the forming mold 11, and the material mass 8 is formed into tableware through the forming mold 11. In this embodiment, the formed tableware is a cup 12; the discharging machine 3 includes a discharging manipulator 13 and a discharging conveyor belt 14, and the discharging manipulator 13 is used to take out the formed tableware from the press 2 and place it on the discharging conveyor belt 14, and the discharging conveyor belt 14 transports the tableware in the direction of the flipping and spraying machine 4; the flipping and spraying machine 4 includes a flipping and lifting mechanism, a flipping mechanism, and a rotating spraying mechanism. The flipping and lifting mechanism is slidably installed on the flipping and spraying machine frame 16 through a mounting bracket 15. The flipping mechanism is connected to the flipping and lifting mechanism, and the flipping and lifting mechanism drives the flipping mechanism to lift and lower. The flipping mechanism includes a number of suction cups (the suction method of the suction cups is negative pressure suction). The rotating spraying mechanism is located on one side of the flipping mechanism. The suction cups of the flipping mechanism cooperate with the flipping and lifting mechanism to suck out some tableware on the discharging conveyor belt 14, and the flipping mechanism flips the tableware, and then the rotating spraying mechanism grabs the inner wall of the flipped tableware for spraying; the baking line 5 includes a tunnel furnace 17 and a baking conveyor belt 18 arranged through the tunnel furnace 17. The sprayed tableware is sent into the tunnel furnace 17 through the baking conveyor belt 18 for baking and then undergoes the next process for packaging.

[0043] The present invention is a fully automated operation. Therefore, an extruder 19 is also provided at the front end of the feeding and arranging machine 1. Corn starch, fiber, etc. are proportioned, stirred, and then put into the extruder 19. The material extruded by the extruder 19 is cut into material masses 8 by a cutter and transported to the feeding conveyor belt mechanism 6 of the feeding and arranging machine 1.

[0044] As Figure 2 、 Figure 3 and Figure 4 shown, the feeding conveyor belt mechanism 6 and the receiving tray mechanism 7 are arranged side by side on the feeding and arranging machine frame 20. The arranging manipulator 9 is erected above the feeding conveyor belt mechanism 6 and the receiving tray mechanism 7, and the feeding manipulator 10 is located below the receiving tray mechanism 7.

[0045] As Figure 3 、 Figure 4 and Figure 9As shown, the incoming material conveyor belt mechanism 6 includes a conveyor belt 21 and profiles 22 arranged at intervals in the width direction of the conveyor belt 21. An active roller and a driven roller are respectively arranged at both ends of the profile 22. The active roller is driven to rotate by a conveyor belt motor 23, and the conveyor belt motor 23 drives the active roller to rotate through a synchronous belt transmission mechanism or a gear transmission mechanism, etc. The conveyor belt 21 is sleeved on the active roller and the driven roller. The profile 22 is supported on the feeding and arranging machine frame 20 through feet 24, and the feeding and arranging machine frame 20 is arranged on the feeding and arranging machine workbench 25.

[0046] In order to enable the arranging manipulator 9 to accurately grasp the material mass 8, a plurality of brackets 26 arranged at intervals are erected above the conveyor belt 21. The brackets 26 are arranged on the profiles 22, and a guide plate 27 for guiding the conveyance of the material mass 8 is connected to the brackets 26. The guide plate 27 is located above the conveyor belt 21.

[0047] The distance between the guide plates 27 in this embodiment can be adjusted according to the size of the material mass 8. A strip-shaped hole is provided at the top of the bracket 26, and the upper end of the guide plate 27 is connected to the strip-shaped hole through a fastener.

[0048] Similarly, in order to adjust the vertical height of the bracket 26, a strip-shaped hole is provided in the vertical direction at the part where the bracket 26 is installed on the profile 22.

[0049] As Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the material receiving tray mechanism 7 includes a material receiving tray 28 and a first baffle 29 slid on the bottom surface of the material receiving tray 28. A plurality of material receiving holes 30 are distributed on the material receiving tray 28, and the arranging manipulator 9 places the material mass 8 into the material receiving holes 30. There are 24 material receiving holes 30 in this embodiment, and the number of material receiving holes 30 can be set according to actual production needs. Both ends of the material receiving tray 28 are slid on the feeding and arranging machine frame 20. The material receiving tray 28 is driven by a first driving mechanism to move back and forth on the feeding and arranging machine frame 20. Whenever a row (transverse) on the material receiving tray 28 is filled by the arranging manipulator 9, the first driving mechanism drives the material receiving tray 28 and the first baffle 29 to move a set distance in the direction of the press 2 until all the material receiving holes 30 on the material receiving tray 28 are filled with the material mass 8. The first driving mechanism is a synchronous belt transmission mechanism. The synchronous belt of the synchronous belt transmission mechanism is fixedly connected to a slider, and the slider is fixedly connected to the material receiving tray 28. A first guide rail 31 is provided on the feeding and arranging machine frame 20, and the slider is slid on the first guide rail 31. The synchronous belt transmission mechanism acts to drive the material receiving tray 28 to reciprocate along the first guide rail 31. The first driving mechanism can also adopt a lead screw transmission mechanism or a chain transmission mechanism, etc.

[0050] The first baffle plate 29 is provided with blanking holes 32 that are in one-to-one correspondence with the receiving holes 30 in terms of position and quantity. The first baffle plate 29 is driven by a first air cylinder 33 to reciprocate back and forth, driving the blanking holes 32 on the first baffle plate 29 to be arranged in one-to-one correspondence with or staggered from the receiving holes 30.

[0051] When the blanking holes 32 are arranged in one-to-one correspondence with the receiving holes 30, the blanking holes 32 and the receiving holes 30 form through holes, and the material mass 8 can fall from the blanking holes 32 and the receiving holes 30 onto the loading manipulator 10; when the blanking holes 32 are staggered from the receiving holes 30, the first baffle plate 29 and the receiving holes 30 form blind holes with the bottom sealed, and the material mass 8 is arranged in the blind holes and does not fall.

[0052] The structure in which the first baffle plate 29 slides on the bottom surface of the receiving tray 28 is as follows:

[0053] A number of long strip holes are arranged on the first baffle plate 29 along the sliding direction, and the length of the long strip holes is the sliding stroke of the first baffle plate 29. Both ends of the first baffle plate 29 are connected through first limit blocks 34, and the first limit blocks 34 are provided with slots, and the first baffle plate 29 and the receiving tray 28 are arranged in the slots. A second limit block 35 is arranged on the bottom surface of the first baffle plate 29. The second limit block 35 includes a bottom plate and a convex block on the upper plane of the bottom plate. The convex block of the second limit block 35 is arranged in the long strip holes, and the second limit block 35 is fixedly arranged on the receiving tray 28 to limit the first baffle plate 29 between the bottom plate and the receiving tray 28.

[0054] As Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, the loading manipulator 10 includes a feeding tray 36, a second baffle plate 37, and a first base 38. A number of feeding holes 39 are distributed on the feeding tray 36. The second baffle plate 37 slides on the bottom surface of the feeding tray 36. The second baffle plate 37 is provided with blanking holes that are in one-to-one correspondence with the feeding holes 39 in terms of position and quantity. The second baffle plate 37 is driven by a second air cylinder to reciprocate back and forth, driving the blanking holes on the second baffle plate 37 to be arranged in one-to-one correspondence with or staggered from the feeding holes 39; the working principles of the feeding tray 36 and the second baffle plate 37 are the same as those of the receiving tray 28 and the first baffle plate 29, and will not be described here. After the receiving tray 28 of the present invention is filled with material masses, they fall onto the receiving tray 36 of the loading manipulator 10 at one time and are sent into the forming die of the press 2 by the loading manipulator 10.

[0055] The lower end of the first base 38 slides on the second guide rail 40, and the second guide rail 40 is arranged on the workbench 25 of the loading and arranging machine. A feeding tray mechanism mounting seat 41 slides on the first base 38, and the feeding tray mechanism mounting seat 41 reciprocates up and down on the first base 38 under the drive of a second drive mechanism.

[0056] Among them, the second driving mechanism includes a lead screw and a lead screw motor. The lead screw nut is fixedly connected to the mounting seat 41 of the feeding tray mechanism. The rotation of the lead screw motor drives the rotation of the lead screw, thereby driving the mounting seat 41 of the feeding tray mechanism to move up and down along the lead screw. To improve stability, in this embodiment, third guide rails 42 are respectively arranged on the first bases 38 at both ends of the lead screw. The second driving mechanism of this embodiment can also be replaced by a gear-rack structure or the like.

[0057] In this embodiment, the first base 38 is driven by a third driving mechanism to move on the second guide rail 40. The third driving mechanism is as follows: It includes a rotating shaft horizontally arranged on the first base 38. Driven synchronous pulleys are respectively arranged at both ends of the rotating shaft. A main synchronous pulley is also arranged on the rotating shaft 44. The main synchronous pulley is driven to rotate by a synchronous belt and a synchronous belt motor 43, thereby driving the rotation of the rotating shaft 44. The strip-shaped synchronous belt 45 is respectively connected to the driven synchronous pulleys. Pressing wheels are arranged on both sides of each driven synchronous pulley. The pressing wheels press on the upper side of the strip-shaped synchronous belt 45. The strip-shaped synchronous belt 45 is fixed to a slider. The slider is arranged on the second guide rail 40. The third driving mechanism of this embodiment can also be implemented by a double-lead screw structure.

[0058] As Figure 3 and Figure 4 shown, the tray placing manipulator 9 includes two support columns 47 erected on the frame 20 of the feeding and tray placing machine. The upper ends of the two support columns 47 are connected by a cross beam 48. A fourth guide rail 49 is arranged on the cross beam 48. A tray placing cylinder 50 is arranged to slide on the fourth guide rail 49 through a slider. A chuck 46 is arranged on the tray placing cylinder 50. The fourth driving mechanism drives the slider to reciprocate along the fourth guide rail 49 to realize the reciprocating movement of the tray placing cylinder 50, and sequentially place the material masses 8 into the corresponding receiving holes 30 on the receiving tray 28. The third driving mechanism is a synchronous belt transmission mechanism. The fourth driving mechanism of this embodiment can be replaced by a gear-rack structure.

[0059] As Figure 11As shown, the discharging manipulator 13 is located above the discharging conveyor belt 14. The discharging manipulator 14 includes a second base 51. A discharging plate mounting seat 52 is slidably arranged on the second base 51 in the vertical direction. One end of the discharging plate 53 is arranged on the discharging plate mounting seat 52, and the other end is arranged in a suspended manner. Suction cups 54 for simultaneously sucking the tableware formed by the press 2 are arranged on the discharging plate 53. The suction cups 54 suck materials by means of negative pressure suction. The second base 51 is driven by a fifth driving mechanism to reciprocate back and forth above the discharging conveyor belt 14. The fifth driving mechanism has the same structure as the third driving mechanism. In order to make the transmission stable, a fifth guide rail is provided. Similarly, the fifth driving mechanism can also be replaced by a double-screw structure. The lifting of the discharging plate mounting seat 52 and the discharging plate 53 on the second base 51 is realized by a sixth driving mechanism. The sixth driving mechanism, like the second driving mechanism, is realized by a screw transmission mechanism. Similarly, it can also be realized by a gear and rack structure.

[0060] As Figures 12 - 17As shown, the flipping glue spraying machine 4 includes a flipping glue spraying machine frame 16. An installation bracket 15 is slidably arranged on the inner top of the flipping glue spraying machine frame 16. The flipping lifting mechanism is arranged on the installation bracket 15. The installation bracket 15 is driven to move by a seventh driving mechanism. A gear motor 61 is arranged on the installation bracket 15, and a gear 62 is arranged on the gear motor 61. A rack 63 is arranged on the inner top of the flipping glue spraying machine frame 16. The gear 62 meshes with the rack 63 for transmission. In order to make the transmission stable, similarly, a sixth guide rail 64 is arranged on the inner top of the flipping glue spraying machine frame 16 along the moving direction of the installation bracket 15. The gear-rack mechanism drives the installation bracket 15 to reciprocate along the sixth guide rail 64. The flipping lifting mechanism includes a first lifting cylinder 55. A flipping mechanism installation bracket 56 is arranged at the lower end of the first lifting cylinder 55. The flipping mechanism includes a U-shaped flipping bracket 57 composed of two side plates and a connecting plate. The two side plates of the flipping bracket 57 are rotatably arranged on the flipping mechanism installation bracket 54. A plurality of sucker brackets 58 are arranged on the inner side surface of the connecting plate. A sucker capable of adsorbing tableware is arranged on each sucker bracket 58. The flipping bracket 57 is driven to rotate by a motor or a rotary cylinder 59. A flipping transition bracket 60 is arranged below the flipping mechanism. When adsorbing tableware, the flipping bracket 57 is horizontally arranged, the sucker brackets 58 on the connecting plate face outwards, and the suckers are arranged in the up-down direction. The seventh driving mechanism drives the installation bracket 15 and the flipping lifting mechanism and the flipping mechanism mounted thereon to move towards the discharging conveyor belt 14. The flipping lifting mechanism drives the flipping bracket 57 to move downwards, so that the suckers adsorb the tableware on the discharging conveyor belt 14. After the sucking action is completed, the seventh driving mechanism drives the installation bracket 15 and the flipping lifting mechanism and the flipping mechanism mounted thereon to reset. At this time, the flipping mechanism is located above the flipping transition bracket 60. The rotary cylinder 59 drives the flipping bracket 57 to rotate 270°, flips the tableware 180°, the suckers stop sucking air, the tableware is separated from the suckers, and the tableware is placed on the flipping transition bracket 60.

[0061] The rotating mechanism is arranged below the installation bracket 15 through a second lifting cylinder 65, and the rotating mechanism is located behind the flipping mechanism. The rotating mechanism includes a driving motor 66 and a number of adsorption heads consistent with the number of suckers. Each adsorption head is rotatably installed on a glue spraying machine frame 67. A glue dispensing cylinder 68 is arranged on the adsorption head. The adsorption heads and the glue dispensing cylinders 68 are driven to rotate simultaneously by the driving motor 66 and a synchronous belt. In this embodiment, one synchronous belt is used. A glue spraying device 69 for spraying glue on the inner wall of the tableware is arranged below the glue dispensing cylinder 68. The rotating mechanism is connected to the second lifting cylinder through a rotating mechanism installation plate 72. A third cylinder 70 is connected between the rotating mechanism installation plate 72 and the rotating mechanism, and the third cylinder 70 drives the rotating mechanism to move back and forth. The glue spraying device 69 includes a glue spraying main pipe, and a number of glue spraying branch pipes are arranged on the glue spraying main pipe. When spraying glue, the tableware is placed above the glue spraying branch pipes.

[0062] When the suction cup on the flipping mechanism moves towards the discharging conveyor belt 14, at this time, the second lifting cylinder 65 drives the suction head and the dispensing cylinder 68 to descend to suck the tableware on the flipping transition bracket 60. The flipping glue spraying machine 4 of the present invention can complete the flipping and glue spraying processes simultaneously.

[0063] In the present invention, a glue spraying shield 71 is provided on the glue spraying device 69. The glue spraying shield 71 can collect the excess glue, prevent the pollution of the surrounding space, and facilitate centralized treatment.

[0064] The actions of each driving mechanism of the present invention are all controlled by a controller.

[0065] The above embodiments are only one of the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the shape, structure, and principle of the present invention should be covered within the protection scope of the present invention.
