[0032] As attached Figure 1 , Attachment Figure 2The biscuit turning and placing machine of the present invention is shown, comprising a conveyor belt 1 for conveying horizontally stacked biscuits 9 and a support frame 2 located above the conveyor belt 1. The conveyor belt 1 has a pushing section 11 for temporarily storing biscuits 9, as shown in the attached figure. Figure 6 As shown, the inlet baffle 12 and the outlet baffle 13 are respectively installed on the front and rear sides of the push section 11 along the conveying direction of the conveyor belt 1, and the push plate 14 is installed between the inlet baffle 12 and the outlet baffle 13. The first limiting cylinder 21, the second limiting cylinder 22 and the push motor 23 are installed on the support frame 2. The output end of the first limiting cylinder 21 is connected to the inlet baffle 12, and the output end of the second limiting cylinder 22 is connected to the outlet baffle 13. The push motor 23 is used to drive the push plate 14 to move in a direction perpendicular to the conveyor belt 1. After the biscuits 9 enter the push section 11 along the conveyor belt, the second limiting cylinder 22 drives the outlet baffle 13 to descend to block the biscuits 9 so that they remain in place. The first limiting cylinder 21 drives the inlet baffle 12 to descend to limit a certain number of biscuits 9 in the push section 11, and then the push motor 23 drives the push plate 14 to push the biscuits 9 to the side.

[0033] A turning device 3 is installed on one side of the conveyor belt 1. Figure 7-9 As shown, the turning device 3 includes a box body 31, a rotating motor 32 and a feeding motor 33. An opening 311 is formed on one side of the box body 31. The rotating motor 32 is used to drive the box body 31 to rotate between a horizontal state and a vertical state. When in the horizontal state, the opening 311 of the box body 31 is connected to the pushing section 11, and the pushing plate 14 pushes the biscuits 9 stacked horizontally in the pushing section 11 into the box body 31. When in the vertical state, as shown in the attached Figure 8 As shown, the opening 311 of the box body 31 is facing upward, so that the biscuits 9 are rotated to a vertical arrangement state. Fig.10 As shown, a top plate 34 is installed on one side of the box body 31 opposite to the opening 311 , and the feeding motor 33 is used to drive the top plate 34 to move the biscuits 9 toward the opening 311 in a vertical state.

[0034] In this embodiment, a parallel first guide rail 24 is installed on the support frame 2, a first slider 25 slidably connected to the first guide rail 24 is installed on the first guide rail 24, a first connecting plate 26 is connected to the two first sliders 25, and a support plate 27 extending downward and connected to the push plate 14 is connected to the first connecting plate 26. A driving pulley 28 is installed at the output end of the push motor 23, and a driven pulley 29 is installed at the end of the support frame 2 away from the push motor 23. A synchronous belt 30 is wrapped around the driving pulley 28 and the driven pulley 29, and the synchronous belt 30 is connected to the first connecting plate 26, so that the push motor 23 drives the push plate 14. As shown in the attached figure Fig. 9As shown, the feeding motor 33 is installed at the bottom of the box body 31. The structure of the feeding motor 33 driving the top plate 34 is similar to the structure of the pushing motor 23 driving the pushing plate 14, and also uses guide rails, sliders, pulleys, synchronous belts and other components.

[0035] A pillow packaging machine 5 is provided on one side of the flipping device 3 , and a parallel robot 6 is installed above the flipping device 3 . The parallel robot 6 is used to grab the biscuits 9 from the opening 311 and place them on the conveyor belt of the pillow packaging machine 5 when the box body 31 is in a vertical state.

[0036] An adjustment plate 35 is installed on one side of the box body 31 adjacent to the opening 311. Fig. 9 As shown, an adjusting cylinder 36 is installed outside the box body 31, and adjusting guide rails 37 are installed on both sides of the adjusting cylinder 36. Adjusting sliders 38 are installed on the adjusting guide rails 37. A second connecting plate 39 is installed at the output end of the adjusting cylinder 36, and the second connecting plate 39 is connected to the adjusting sliders 38 on both sides. The adjusting plate 35 is connected to the second connecting plate 39 and moves in the same or opposite direction to the conveying direction of the conveyor belt 1 under the drive of the adjusting cylinder 36, so as to adjust the width inside the box body 31 and perform side positioning to adapt to biscuits of different widths.

[0037] A floating pressure plate 41 is installed in the box body 31. Figure 7 As shown, when in a horizontal state, the floating pressure plate 41 is close to the upper part of the box body 31, and a sliding rod 42 passing through the box body 31 is connected to the floating pressure plate 41, and a connecting piece 43 is installed at the end of the sliding rod 42. A sliding bearing 40 is installed on the box body 31, and the sliding rod 42 passes through the sliding bearing 40, making the movement more stable and smooth. A floating cylinder 44 is installed on the box body 31, and the output end of the floating cylinder 44 is connected to a mounting plate 45, and floating rods 46 are connected to both sides of the mounting plate 45. A spring 47 is sleeved on the floating rod 46, and the end of the floating rod 46 is embedded in the connecting piece 43. When the thickness of the biscuits 9 loaded in the box body 31 changes, the floating cylinder 44 moves to enable the floating pressure plate 41 to fit the biscuits 9 and reposition the biscuits 9 within the range of ±5mm. The combined movement of the adjustment plate 35 and the floating pressure plate 41 can position and adjust the biscuits 9 of different lengths, widths and thicknesses, preventing the biscuits 9 from loosely shaking in the box body 31, and keeping the stacked biscuits 9 compact so that the parallel robot 6 can accurately position and grab the biscuits 9.

[0038] In this embodiment, there are two pushing intervals 11, and the two flipping devices 3 correspond to the two pushing intervals 11 respectively, and the time when the two flipping devices 3 are in the horizontal state or the vertical state is staggered with each other, so as to maintain a continuous working state and improve the efficiency of flipping and placing the biscuits 9.

[0039] The end of the parallel robot 6 is equipped with a grasping mechanism 7, as shown in the attached Fig.11As shown, the grabbing mechanism 7 includes a bracket 71, on which a variable pitch cylinder 72 and a second guide rail 73 extending to both ends are mounted, a second slide block 74 is connected to the second guide rail 73, and the output end of the variable pitch cylinder 72 is connected to the second slide block 74. A fixed clamping jaw 75 is mounted in the center of the bracket 71, and movable clamping jaws 76 respectively connected to the second slide block 74 are mounted at both ends of the fixed clamping jaw 75, so as to adjust the distance between the clamping jaws to adapt to grabbing biscuits 9 of different widths.

[0040] The conveyor belt 1 is a roller conveyor belt, which reduces the contact area between the biscuits 9 and the conveyor belt 1. If the biscuits 9 produce debris during the movement, it can fall through the gap of the roller 15 to avoid accumulation on the conveyor belt 1 and causing pollution. A detachable slag collection box 8 is installed under the roller 15 of the conveyor belt 1. The biscuit residues 9 fall through the gap of the roller 15 and fall into the slag collection box 8 to avoid falling everywhere and polluting the environment. It is convenient to collect and makes the production line neater. Figure 5 As shown, the bottom of the push plate 14 has teeth 141 inserted into the gap between the rollers 15, so that the push plate 14 pushes all the biscuits 9 in the pushing interval into the box body 31 to avoid missing the biscuits 9 at the bottom.

[0041] When the biscuit 9 flipping and placing machine of the present invention is used, the horizontally stacked biscuits 9 are allowed to enter the pushing section 11 along the conveyor belt 1, the outlet baffle 13 is lowered to prevent the biscuits 9 from moving forward, the inlet baffle 12 is lowered to limit the biscuits 9 in the pushing section 11, the pushing plate 14 pushes the biscuits 9 into the box body 31 with one side in a horizontal state, the adjustment plate 35 in the box body 31 moves laterally to position the biscuits 9 in the width direction, and the floating pressing plate 41 in the box body 31 is pressed down to position the biscuits 9 in the thickness direction, so that the biscuits 9 are kept in a compact and gathered state. Then the box body 31 rotates to a vertical state with the opening 311 facing upward, so that the horizontally stacked biscuits 9 are converted into a vertical state that is easier to grasp. The grasping mechanism 7 at the end of the parallel robot 6 grasps the biscuits 9 from the opening 311 of the box body 31 and places them in the pillow packaging machine 5 for packaging. At this time, the top plate 34 at the bottom of the box body 31 gradually moves upward to lift the biscuits 9 upward, filling the vacancies left by the biscuits 9 above being grasped away, so that the grasping mechanism 7 can repeatedly grasp in the original position, completing the automated grasping, placing and packaging process of the biscuits 9, thereby improving the packaging efficiency.
