[0034] The driving mechanism drives the loading mechanism to operate, enabling the suction cup to suck citrus fruits from the to-be-loaded tank and load them into the tray on the loading conveyor. Each time a group of citrus fruits is placed in the tray, the driving mechanism simultaneously drives the ratchet mechanism to operate once, causing the ratchet mechanism to drive the loading conveyor to operate once, moving the tray once, so that the empty position on the tray moves below the suction cup, waiting for the next group of citrus fruits to be loaded. By loading citrus fruits onto the tray multiple times, the tray can be filled up.

[0035] After the tray is filled with citrus fruits, the translation mechanism drives the tray to move onto the packaging conveyor. The packaging conveyor transports the tray with citrus fruits into the interior of the packaging machine for sealing, thus achieving the packaging of citrus fruits. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0046] Please refer to Figure 1-8 , the present invention provides a technical solution: an intelligent citrus packaging device, including a loading machine 1, the output end of the loading machine 1 is connected to a material distributor 2 for equally separating citrus, there are a plurality of loading slots 3 on one side of the material distributor 2, the citrus on the material distributor 2 is conveyed into the loading slots 3 through a material pushing mechanism 4, a plurality of limit blocks 21 for separating citrus are evenly distributed on the conveyor belt of the material distributor 2, there are a plurality of notches 22 on one side of the material distributor 2, the loading slots 3 are inclined and installed on one side of the material distributor 2, and the loading slots 3 are connected to the notches 22 in a matching manner;

[0047] A loading conveyor 5 is arranged on one side of the material distributor 2, the loading conveyor 5 is controlled to run intermittently through a ratchet mechanism 6, a tray 7 for containing citrus is arranged at the upper end of the loading conveyor 5, the citrus inside the loading slots 3 is loaded into the tray 7 through a loading mechanism 8, and both the loading mechanism 8 and the ratchet mechanism 6 are controlled to operate through a driving mechanism 9;

[0048] A packing conveyor 10 is arranged side by side on one side of the loading conveyor 5. After the pallet 7 is loaded, it is controlled by the translation mechanism 11 to move onto the packing conveyor 10. A packing machine 12 for packing the loaded pallet 7 is provided on the packing conveyor 10.

[0049] Among them, the feeding machine 1 is an existing mature device. The feeding machine 1 is high at one end and low at the other end. A storage bin is arranged at the lower end. During operation, first pour the citrus into the storage bin at one end of the feeding machine 1. The feeding machine 1 separates the citrus individually by moving through the internal rollers and conveys the individually separated citrus to the higher end. When it reaches the highest position of the feeding machine 1, it falls onto the distributing machine 2. The distributing machine 2 is also an existing mature device. A plurality of limiting blocks 21 are evenly distributed on the conveyor belt in the middle of the distributing machine 2. The citrus will fall between each limiting block 21 in turn. The limiting blocks 21 can separate the citrus at equal distances. The conveyor belt on the distributing machine 2 drives the citrus to move towards the position of the waiting-to-be-loaded groove 3. When a group of citrus moves to correspond to a plurality of notches 22 on one side of the distributing machine 2, the dialing mechanism 4 dials the citrus, so that the citrus rolls into the waiting-to-be-loaded groove 3 from the notch 22. The inclined waiting-to-be-loaded groove 3 facilitates the movement of the citrus. Then the driving mechanism 9 drives the loading mechanism 8 to operate, so that a group of citrus in the waiting-to-be-loaded groove 3 is loaded into the pallet 7 on the loading conveyor 5. Every time a group of citrus is placed in the pallet 7, the driving mechanism 9 simultaneously drives the ratchet mechanism 6 to operate once, so that the ratchet mechanism 6 drives the loading conveyor 5 to operate once, the pallet 7 moves once, and the empty position on the pallet 7 moves below the suction cup 89 to wait for the next group of citrus to be loaded. After the pallet 7 is full, the translation mechanism 11 drives the pallet 7 to move onto the packing conveyor 10. After the pallet 7 moves onto the packing conveyor 10, the packing conveyor 10 starts to convey the pallet 7 with citrus into the packing machine 12 for encapsulation.

[0050] The dialing mechanism 4 includes a second fixing frame 41 fixed on one side of the distributing machine 2. A dialing shaft 42 is rotatably installed on the second fixing frame 41, and the dialing shaft 42 is located in the middle above the distributing machine 2. The dialing shaft 42 is controlled to rotate by a first motor 44. A plurality of groups of dialing plates 43 are arranged in the radial direction of the dialing shaft 42, and each group of dialing plates 43 matches the waiting-to-be-loaded groove 3.

[0051] Among them, the dialing mechanism 4 is in a continuous operating state. By controlling the rotation speed of the dialing shaft 42, when the dialing plates 43 dial the citrus, a group of citrus just moves to the notch 22 position. During operation, the first motor 44 drives the dialing shaft 42 and the dialing plates 43 on the dialing shaft 42 to rotate. When a group of citrus just moves to the notch 22 position, the dialing plates 43 just contact the citrus and dial the citrus towards the notch 22 direction, so that the citrus rolls into the waiting-to-be-loaded groove 3 through the notch 22 and waits for the next step of loading.

[0052] The loading mechanism 8 includes a fixed frame 81 located on one side of the loading conveyor 5, a swing arm 82 is rotatably installed on one side of the fixed frame 81 near the upper end, the swing arm 82 is controlled by the driving mechanism 9 to swing on the fixed frame 81, one end of the swing arm 82 is rotatably connected to a feeding plate 83, a vertical guide rail 84 is provided on one side of the feeding plate 83, a vertical slider 85 is vertically slidably connected to the vertical guide rail 84, a horizontal plate 86 is provided near the upper end of the fixed frame 81, a horizontal guide rail 87 is provided on one side of the horizontal plate 86, a horizontal slider 88 is horizontally slidably connected to the horizontal guide rail 87, and the horizontal slider 88 is fixedly connected to the vertical slider 85, and a plurality of suction cups 89 for sucking citrus fruits are installed at the bottom of the feeding plate 83, and the suction cups 89 match the positions of the slots 3 to be loaded;

[0053] The driving mechanism 9 includes a cylinder 91 located on one side of the fixed frame 81, a rack 92 is provided at the output end of the cylinder 91, a gear 93 is fixedly connected to the swing arm 82 via a rotating shaft, and the gear 93 is meshed with the rack 92;

[0054] The ratchet mechanism 6 includes a lifting rod 61 slidably mounted on the back of a fixed frame 81, an upper rack 62 is provided at the upper end of the lifting rod 61, and the upper rack 62 is meshed with a gear 93. A lower rack 63 is provided at the lower end of the lifting rod 61, and the lower rack 63 is meshed with a half gear 64, and the half gear 64 is rotatably mounted on one side of the fixed frame 81. A swing plate 65 is provided in the radial direction of the half gear 64, and a fixed shaft 66 is provided at one end of the swing plate 65. A toggle plate 67 is rotatably mounted on the fixed shaft 66, and one end of the toggle plate 67 is a circular arc structure. A limit column 68 is provided near the side of the swing plate 65, and the other end of the toggle plate 67 is It is connected to the limit column 68 through a spring 1 69, and a ratchet 610 is also rotatably installed on the fixed frame 81. The ratchet 610 is driven to rotate by the toggle plate 67. A pawl 611 is provided on one side of the ratchet 610 to prevent the ratchet 610 from reversing. One end of the pawl 611 is rotatably installed on the fixed frame 81, and a spring 2 612 is provided on one side of the pawl 611 for driving the pawl 611 to reset. A synchronous wheel 1 613 is provided on one side of the loading conveyor 5 for driving the same to operate. A synchronous wheel 2 614 is provided on one side of the ratchet 610. The synchronous wheel 2 614 and the synchronous wheel 1 613 are connected through a synchronous belt 615.

[0055] When the driving mechanism 9, the loading mechanism 8 and the ratchet mechanism 6 are working, the cylinder 91 drives the rack 92 to descend, so that the gear 93 rotates 180 degrees, so that the swing arm 82 rotates 180 degrees, so that the swing arm 82 rotates from the side close to the tray 7 to the side close to the slot 3 to be loaded, so that the picking plate 83 moves from above the tray 7 to above the slot 3 to be loaded, as shown in FIG. Figure 1 and Figure 2Position of the material taking plate 83. During the movement of the material taking plate 83, the horizontal slider 88 slides from one end of the horizontal guide rail 87 to the other end, and the vertical slider 85 slides from the upper end of the vertical guide rail 84 to the lower end and then returns to the upper end of the vertical guide rail 84 again. At this time, a set of suction cups 89 at the bottom of the material taking plate 83 control the suction of the citrus fruits on the to-be-loaded groove 3 through an air pump (not shown in the figure). Then, the first cylinder 91 drives the first rack 92 to rise, causing the first gear 93 to rotate 180 degrees in the opposite direction again, so that the material taking plate 83 moves from above the to-be-loaded groove 3 to above the tray 7, and then places the citrus fruits sucked on the suction cups 89 into the tray 7. There are multiple sets of pit positions for holding citrus fruits on the tray 7. Therefore, it is necessary to suck the citrus fruits on the to-be-loaded groove 3 multiple times and place them on the tray 7 until the tray 7 is full. When a set of citrus fruits is placed on the tray 7, through the driving mechanism 9 and the loading mechanism 8, the material taking plate 83 will move above the to-be-loaded groove 3 again to suck the next set of citrus fruits. During the movement of the material taking plate 83 above the to-be-loaded groove 3, the first gear 93 rotates, causing the upper rack 62 at the upper end of the lifting rod 61 to move upward. Through the lifting rod 61, the lower rack 63 also moves upward, causing the half gear 64 to rotate clockwise. The swing plate 65 on one side of the half gear 64 also rotates clockwise, causing the toggle plate 67 rotatably mounted on the fixed shaft 66 to rotate clockwise. The end of the toggle plate 67 with an arc downward pushes the ratchet teeth of the ratchet wheel 610. Since the limit post 68 limits the other end of the toggle plate 67, when the toggle plate 67 pushes the ratchet teeth 610 downward, the toggle plate 67 will not rotate with respect to the fixed shaft 66, enabling the toggle plate 67 to push the ratchet wheel 610 to rotate counterclockwise, causing the first synchronous wheel 613 to rotate. Through the synchronous belt 615, the second synchronous wheel 614 rotates, causing the second synchronous wheel 614 to drive the loading conveyor 5 to operate. Therefore, the tray 7 at the upper end of the loading conveyor 5 can move a certain distance. While the ratchet wheel 610 rotates, the ratchet wheel 610 squeezes one side of the pawl 611, causing one end of the pawl 611 to rotate, and the other end to move away from the ratchet wheel 610. At this time, the second spring 612 is compressed. When the rotation of the ratchet wheel 610 is completed, the pawl 611 will disengage from one ratchet tooth of the ratchet wheel 610, and through the rebound force of the second spring 612, the pawl 611 will snap into another ratchet tooth of the ratchet wheel 610. When the material taking plate 83 sucks the citrus fruits from the to-be-loaded groove 3, the material taking plate 83 moves above the tray 7 again through the driving mechanism 9 and the loading mechanism 8. Since the tray 7 moves a certain distance, the pit position on the tray 7 directly below the suction cups 89 for holding citrus fruits is in an empty state. At this time, the citrus fruits can be placed on the tray 7, thus realizing the placement of the second group of citrus fruits. When the material taking plate 83 moves from above the to-be-loaded groove 3 to above the tray 7, the first gear 93 drives the upper rack 62, the lifting rod 61, and the lower rack 63 to move downward, causing the half gear 64 to rotate counterclockwise. Through the swing plate 65, the toggle plate 67 rotates counterclockwise. At this time, the end of the toggle plate 67 with an arc upward presses against the ratchet wheel 610.Since the pawl 611 limits the ratchet 610, the ratchet 610 will not rotate clockwise, so the ratchet 610 is in a stationary state, and the swing plate 65 continues to rotate counterclockwise. The end of the toggle plate 67 with the arc is limited by the ratchet 610, so that the toggle plate 67 rotates. At this time, the limit column 68 no longer limits the toggle plate 67, and the other end of the toggle plate 67 rotates clockwise and moves away from the limit column 68, and the end of the toggle plate 67 with the arc moves from one side of the ratchet teeth of the ratchet 610 to the other side. Therefore, when the picking plate 83 moves from above the slot 3 to be loaded to above the tray 7, the ratchet 610 will not rotate, so that the loading conveyor 5 will not run. Therefore, the loading conveyor 5 is intermittent in one direction, so that the tray 7 is intermittent in one direction, thereby realizing the loading of the tray 7.

[0056] The translation mechanism 11 includes a fixed frame three 111 fixed on the upper side of one end of the loading conveyor 5 and the packaging conveyor 10, a translation guide rail 112 is provided on one side of the fixed frame three 111, the translation guide rail 112 is slidably connected with a translation frame 113, and an opening is provided on the side of the translation frame 113 close to the tray 7, the fixed frame three 111 is rotatably installed with a screw rod 114, the screw rod 114 is driven to rotate by a motor two 115, a nut block 116 is provided in the middle of the upper end of the translation frame 113, and the nut block 116 is connected to the screw rod 114 by threads.

[0057] The translation mechanism 11 is used to move the tray 7 filled with citrus fruits to the packaging conveyor 10. When the tray 7 is filled with citrus fruits, one side of the tray 7 just enters the interior of the translation frame 113. Figure 7 The motor 115 drives the screw rod 114 to rotate, so that the translation frame 113 slides on the translation guide rail 112, so that the tray 7 can be moved from the loading conveyor 5 to the packaging conveyor 10. When the tray 7 moves to the packaging conveyor 10, the packaging conveyor 10 starts to transport the tray 7 containing citrus fruits to the packaging machine 12 for packaging, thereby realizing the packaging of citrus fruits.

[0058] A pallet conveyor 13 for conveying the pallet 7 to the loading conveyor 5 is provided at one end of the loading conveyor 5, and the pallet conveyor 13 is higher than the loading conveyor 5. After the pallet 7 is conveyed to the loading conveyor 5, it is limited by a limiting mechanism 14;

[0059] A roller 131 is rotatably mounted at the output end of the pallet conveyor 13, the height of the roller 131 is located between the pallet conveyor 13 and the loading conveyor 5, and the roller 131 is located at the input end of the loading conveyor 5;

[0060] The limiting mechanism 14 includes a fourth fixing frame 141 located on one side at the upper end of the loading conveyor 5. A limiting plate 142 is rotatably installed on the fourth fixing frame 141. The limiting plate 142 is connected to a second gear 143 through a rotating shaft. The second gear 143 is meshed and connected to a second rack 144. The second rack 144 is controlled to move by a second air cylinder 145. Guide plates 146 for limiting both sides of the tray 7 are also provided on both sides of the loading conveyor 5.

[0061] Among them, the tray 7 on the loading conveyor 5 is intermittently supplied by the tray conveyor 13. After the tray 7 on the loading conveyor 5 is moved onto the packaging conveyor 10, the second air cylinder 145 drives the second rack 144 to move, causing the second gear 143 to rotate 180 degrees, and the limiting plate 142 to rotate 180 degrees and lie horizontally on the loading conveyor 5. Then the tray conveyor 13 starts to operate, and the tray 7 moves from the rotating roller 131 to the loading conveyor 5 by the inertia of movement. The guide plates 146 on both sides of the loading conveyor 5 enable the tray 7 to move to the middle of the loading conveyor 5. The limiting plate 142 lying horizontally on the loading conveyor 5 can limit the stopping position of the tray 7, such as Figure 8 The limiting plate 142 limits the tray 7, enabling the tray 7 to stay at a reasonable loading position. After the tray 7 stops on the loading conveyor 5, the second air cylinder drives the limiting plate 142 to leave the tray 7 and stand on one side of the loading conveyor 5.

[0062] An intelligent citrus packaging method, used in conjunction with an intelligent citrus packaging device, includes the following steps:

[0063] S1. Feeding: Pour the citrus into the feeding machine 1. The feeding machine 1 separates the citrus individually and conveys the separated citrus into the distributing machine 2.

[0064] S2. Distributing: After the citrus enters the conveyor belt of the distributing machine 2, it is in an equidistant separated state. When the citrus moves to a position corresponding to the notch 22 on one side of the distributing machine 2, a group of citrus is dialed into the waiting-to-be-loaded slot 3 by the dialing piece 43 of the dialing mechanism 4.

[0065] S3. Loading: Drive the loading mechanism 8 to operate through the driving mechanism 9, so that the suction cup 89 moves above the waiting-to-be-loaded slot 3 and sucks a group of citrus, and then puts the citrus onto the tray 7 on the loading conveyor 5. The loading mechanism 8 takes and places the materials intermittently multiple times until the tray 7 is full.
