The side of the first conveying support frame 21 is also provided with an industrial camera 26 for detecting whether the material is incomplete.

[0024] After wrapping the cutlery with napkins, put them into the material storage plate 25. Then the first drive motor 24 drives the shaft of the first reducer 23 to rotate. During the rotation of the first reducer 23, the first belt drive shaft 22 can be driven to rotate. The first belt drive shaft 22 drives the first conveyor belt 27 and the material storage plate 25 on the surface of the first conveyor belt 27 to reciprocate. During the movement of the first conveyor belt 27, the industrial camera 26 is used to detect whether the package is complete and whether the cutlery is complete. Whenever the wrapped cutlery is transported to the bottom of the material picking mechanism 4 by the material storage plate 25, the material picking mechanism 4 can grab each material and place it on the surface of the corresponding second conveying mechanism 3 according to the detection results of the industrial camera 26.

[0025] The second conveying mechanism 3 includes a second conveying support frame 31, a second conveying belt 32, a second reducer 33 and a second driving motor 34. Second belt driving shafts are provided at both ends of the second conveying support frame 31. A second conveying belt 32 is provided on the surface of the second belt driving shaft. At least one end of the second belt driving shaft is transmission-connected with the second reducer 33, and one side of the second reducer 33 is transmission-connected with the second driving motor 34.

[0026] The two sets of second conveying mechanisms 3 can be used to convey unwrapped defective products and defective products with missing knives, forks and spoons. The material taking mechanism 4 places these defective products on the surface of the second conveyor belt 32. Similarly, the second driving motor 34 drives the rotating shaft of the second reducer 33 to start rotating, and the second reducer 33 drives the second conveyor belt 32 through the second belt body driving shaft to transport the materials to the outside.

[0027] Please continue to refer to Figure 3 and Figure 4As shown in the figure, the material taking mechanism 4 includes a first electric slide rail 41, a first cylinder 42, a material taking support frame 45, a rotary cylinder 43 and a clamping assembly 44.

[0028] The clamping assembly 44 includes a clamping support plate 441, a double piston cylinder 442, a material clamping jaw 443, a second cylinder 444, a first adsorption support 445 and a first pneumatic suction cup 446. The bottom of the clamping support plate 441 is connected with a double piston cylinder 442 and a second cylinder 444. The ends of the piston rods on both sides of the double piston cylinder 442 are connected with material clamping jaws 443. The end of each material clamping jaw 443 is adapted to the shape of the middle part of the material. The end of the piston rod of the second cylinder 444 is connected with a first adsorption support 445, and the inside of the first adsorption support 445 is connected with a first pneumatic suction cup 446. The first pneumatic suction cup 446 can adsorb the end of the material.

[0029] The material taking support frame 45 is erected above the first conveying mechanism 2 and the second conveying mechanism 3. The slider on the first electric slide rail 41 can move above the first conveying mechanism 2 or the second conveying mechanism 3. When the slider on the first electric slide rail 41 moves to the designated position, the piston rod of the first cylinder 42 moves downward, thereby driving the rotary cylinder 43 and the parts adapted to the bottom to move downward at the same time. Then the rotary cylinder 43 adjusts the angle, so that the piston rods on both sides of the double piston cylinder 442 drive each material clamping jaw 443 to move inward, thereby clamping the material. After clamping, in order to further stabilize the firmness of the clamping, the first pneumatic suction cup 446 can adsorb the end of the column material, thereby completing the entire clamping operation. If it is necessary to put down the material, similarly adjust the position, then loosen the material clamping jaws 443 so that they fall on the surface of the first conveyor belt 27 or the second conveyor belt 32.

[0030] In this embodiment, as shown in the reference Figure 5 、 Figure 8 and Figure 9As shown, a material stacking platform 5 capable of sliding relative to the first support table 1 is provided at the lower side of the material picking mechanism 4, and the material stacking platform 5 includes a first stacking platform 51, a first slider 52, a first slide rail 53 and a third cylinder 54.

[0031] The second support table 11 is a surface fixedly connected to the first support table 1. When the position of the first stacking platform 51 needs to be adjusted, the piston rod of the third cylinder 54 pushes the first stacking platform 51 to move. During the displacement process, the first slider 52 moves simultaneously with the first stacking platform 51, and at the same time, the first slider 52 slides relative to the first slide rail 53, and the first slide rail 53 plays a supporting and guiding role.

[0032] like Figure 7 and Figure 9 The material stacking platform 5 is provided with a material limiting mechanism 6 for limiting the position of the material, and the material limiting mechanism 6 can slide up and down relative to the material stacking platform 5 .

[0033] The material limiting mechanism 6 includes a first limiting baffle plate 61, a limiting driving plate 62 and a fourth cylinder 63. The surface of the first stacking platform 51 is provided with a plurality of first avoidance grooves 511, each of which is slidably connected to a first limiting baffle plate 61. The bottoms of the plurality of first limiting baffle plates 61 are connected to one side of the limiting driving plate 62, and the other side of the limiting driving plate 62 is connected to the fourth cylinder 63. exist Figure 7 In the process, the piston rod of the fourth cylinder 63 is retracted to drive each first limit baffle 61 to move downward through the limit driving plate 62, and the first limit baffle 61 slides downward from the inside of the first avoidance groove 511 during the movement, until all the first limit baffles 61 are separated from the surface of the first stacking platform 51.

[0034] exist Figure 5 In the embodiment, the piston rod of the fourth cylinder 63 is in an extended state, so each first limit baffle 61 protrudes upward through the interior of the first avoidance groove 511. At this time, the gap between adjacent first limit baffles 61 can be used to place materials, and the material taking mechanism 4 can stack the good products on the surface of the first conveyor belt 27 in the gaps between adjacent first limit baffles 61 until the set number is stacked.

[0035] In this embodiment, if Figure 1 , Figure 2 and Figure 5 A bag placing mechanism 9 and a bag feeding mechanism 10 are also provided on one side of the surface of the first supporting table 1 close to the end of the bag holding mechanism 8 .

[0036] The bag loading mechanism 10 includes a loading support frame 101, a second electric slide rail 102, a seventh cylinder 103, a suction cup support frame 104, a bag body placement frame 106 and a bag body limiting column 107. The side of the loading support frame 101 is provided with a second electric slide rail 102, the surface of the slider on the second electric slide rail 102 is connected to the seventh cylinder 103, the piston rod end of the seventh cylinder 103 is connected to the suction cup support frame 104, the bottom of the suction cup support frame 104 is provided with a plurality of third pneumatic suction cups 105, the surface of the bag body placement frame 106 is provided with a plurality of bag body limiting columns 107, and the bag body placement frame 106 is arranged on the surface of the first support table 1.

[0037] A large number of packaging bags are stacked and placed between adjacent bag limiting columns 107. When the packaging bags need to be transported to the surface of the bag placement mechanism 9, the slider on the second electric slide rail 102 first slides to adjust the position so that the suction cup support frame 104 moves to the top of the bag placement frame 106, and then the piston rod of the seventh cylinder 103 extends so that each third pneumatic suction cup 105 absorbs the plastic belt. Similarly, the second electric slide rail 102 and the seventh cylinder 103 are used to adjust the position until the packaging bags are transported to the surface of the bag placement mechanism 9.

[0038] The bag placing mechanism 9 includes a bag placing platform 91 and a second pneumatic suction cup 92. The surface of the second supporting table 11 is also provided with a bag placing platform 91. A plurality of second pneumatic suction cups 92 are provided between the bag placing platform 91 and the surface of the second supporting table 11. The end of each second pneumatic suction cup 92 is provided on the surface of the bag placing platform 91.

[0039] When the packaging bag moves to the surface of the bag body placement platform 91, the top of the packaging bag is sucked by the third pneumatic suction cup 105, and the second pneumatic suction cup 92 sucks the bottom of the packaging bag. Then the entire packaging bag will be opened to wait for subsequent packaging operations.

[0040] In this embodiment, if Figure 1 and Figure 5 As shown in FIG. 1 , the surface of the material stacking platform 5 is further provided with a material pushing mechanism 7 for pushing the material into the bag body and a bag holding mechanism 8 for holding open the bag body.

[0041] The bag supporting mechanism 8 includes a first bag-opening support plate 81, a fifth cylinder 82, a bag-supporting support frame 83, a sixth cylinder 84 and a second bag-opening support plate 85. The surface of the first stacking platform 51 is provided with a number of first bag-opening support plates 81 for supporting both sides inside the bag body. The side of each first bag-opening support plate 81 is connected with a fifth cylinder 82. During the telescopic movement of the piston rod of the fifth cylinder 82, the distance between the first bag-opening support plate 81 and the first limit baffle 61 can be changed. The surface of the first stacking platform 51 is also provided with a bag-supporting support frame 83. The surface of the bag-supporting support frame 83 is provided with a sixth cylinder 84. The end of the piston rod of the sixth cylinder 84 is connected with a second bag-opening support plate 85 for opening the top of the bag body.

[0042] After the opening of the packaging bag described above is opened on the bag body placement platform 91, the piston rod of the fifth cylinder 82 extends, so that the distance between the first bag-opening support plate 81 and the first limit baffle 61 becomes smaller, to prevent the first bag-opening support plate 81 from puncturing both sides of the packaging bag. Then, the piston rod of the third cylinder 54 pushes the first stacking platform 51 to move to the right until the first stacking platform 51 fits against the left side of the bag body placement platform 91. At this time, each first bag-opening support plate 81 is located inside the packaging. Then, the piston rod of the fifth cylinder 82 retracts, and the first bag-opening support plate 81 gradually enlarges both sides inside the packaging bag during the movement. The piston rod of the sixth cylinder 84 retracts, and the second bag-opening support plate 85 is used to open the top of the bag body to facilitate the subsequent entry of the packaged materials.

[0043] At this time, both sides of the packaging are opened by the first bag-opening support plate 81, the bottom of the packaging bag is sucked by the second pneumatic suction cup 92, and the top of the packaging bag is sucked by the third pneumatic suction cup 105 to complete the opening of the packaging bag. Then, with the first limit baffle 61 retracted, the material is pushed into the packaging bag by the pushing mechanism 7.

[0044] In this embodiment, as Figure 5 described, the pushing mechanism 7 includes a pushing support frame 71, an eighth cylinder 72, a slide rail support block 73 and a second slide rail 74. The inside of the pushing support frame 71 is provided with an eighth cylinder 72. The surface of the first stacking platform 51 is provided with a slide rail support block 73. The surface of the slide rail support block 73 is slidably connected with a second slide rail 74. The end of the piston rod of the eighth cylinder 72 and the end of the second slide rail 74 are connected with a pushing baffle 75.

[0045] During the pushing process, the piston rod of the eighth cylinder 72 extends to drive the pushing baffle 75 to move to the right. During the movement, the second slide rail 74 slides relative to the surface of the slide rail support block 73, playing a role in support and guidance.

[0046] The working principle and usage method of the present invention: Wrap the knife, fork and spoon with a paper napkin and place them inside the material storage plate 25. Then, the first drive motor 24 drives the rotation of the rotating shaft of the first reducer 23. During the rotation of the first reducer 23, the first belt drive shaft 22 can be driven to rotate. The first belt drive shaft 22 drives the first conveyor belt 27 and the material storage plate 25 on the surface of the first conveyor belt 27 to move reciprocally. During the movement of the first conveyor belt 27, the industrial camera 26 is used to detect whether the package is complete and whether the knife, fork and spoon are complete.

[0047] Whenever the wrapped knife, fork and spoon materials are transported to the lower part of the material taking mechanism 4 by the material storage plate 25, the slider on the first electric slide rail 41 can move above the first conveying mechanism 2 or the second conveying mechanism 3. When the slider on the first electric slide rail 41 moves to the specified position, the piston rod of the first cylinder 42 moves downward, driving the rotary cylinder 43 and the parts adapted to the bottom to move downward simultaneously. Then, the rotary cylinder 43 adjusts the angle, so that the piston rods on both sides of the double piston cylinder 442 drive each material gripper 443 to move inward, thereby gripping the material. After gripping, in order to further stabilize the firmness of the grip, the first pneumatic suction cup 446 can adsorb the end of the column material, thus completing the entire gripping operation. If it is necessary to put down the material, after adjusting the position in the same way, release the material gripper 443 so that it falls on the surface of the first conveyor belt 27 or the second conveyor belt 32.

[0048] Then, keep the piston rod of the fourth cylinder 63 in the extended state, and each first limit baffle 61 protrudes upward through the inside of the first avoidance groove 511. The gap between adjacent first limit baffles 61 can be used to place materials, and the material taking mechanism 4 can stack the good products on the surface of the first conveyor belt 27 inside the gap between adjacent first limit baffles 61.

[0049] After stacking to the set quantity, the slider on the second electric slide rail 102 slides to adjust the position first, so that the suction cup support frame 104 moves above the bag placing rack 106. Then, the piston rod of the seventh cylinder 103 extends so that each third pneumatic suction cup 105 adsorbs the plastic belt. Similarly, use the second electric slide rail 102 and the seventh cylinder 103 to adjust the position until it is conveyed to the surface of the bag placing platform 91. Use the first spreading support plate 81 to spread both sides of the package, use the second pneumatic suction cup 92 to suck the bottom of the packaging bag, and use the third pneumatic suction cup 105 to suck the top of the packaging bag to complete the spreading of the packaging bag.

[0050] The piston rod of the fifth cylinder 82 extends, reducing the distance between the first supporting plate 81 and the first limiting baffle 61 to prevent the two sides of the packaging bag from being punctured by the first supporting plate 81. Then, the piston rod of the third cylinder 54 pushes the first stacking platform 51 to move rightward until the first stacking platform 51 abuts against the left side of the bag placing platform 91. At this time, each first supporting plate 81 is located inside the packaging. Subsequently, the piston rod of the fifth cylinder 82 retracts, and the first supporting plate 81 gradually expands the inner sides of the packaging bag during the movement.

[0051] Finally, the piston rod of the fourth cylinder 63 retracts, driving each first limiting baffle 61 to move downward through the limiting driving plate 62. During the movement, the first limiting baffle 61 slides downward from the inside of the first avoidance groove 511. Until all the first limiting baffles 61 are separated from the surface of the first stacking platform 51, the piston rod of the eighth cylinder 72 extends to drive the pushing baffle 75 to move rightward. The pushing baffle 75 pushes all the materials into the packaging bag. During the movement, the second slide rail 74 slides relative to the surface of the slide rail support block 73.

[0052] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
