[0002] In the circulation and transportation of fruit and vegetable products, in order to effectively prevent damage and maintain product quality, net packaging technology has gradually been widely used. As an effective buffer material, the net can significantly reduce the collision and friction of fruits and vegetables during transportation, thereby reducing the loss rate and ensuring the freshness and integrity of fruits and vegetables. Existing fruit and vegetable nets are mainly operated manually, which is time-consuming and labor-intensive. Not only is the netting efficiency low, but there is also a high labor cost, which makes it difficult to meet the large-scale fruit packaging needs.

[0026] The fixed frame 100 can be made of sheet metal or aluminum profiles and is used to support and fix other components. The fruit and vegetable conveying mechanism is fixed on the fixed frame 100. A tray 221 is provided on the fruit and vegetable conveying mechanism for placing fruits and vegetables. The fruits and vegetables are spherical in shape, such as apples, oranges, potatoes, etc., to ensure that the fruits and vegetables will not be displaced or dropped during the conveying process; the fruit and vegetable conveying mechanism is driven to move to convey the fruits and vegetables. Fig.10 As shown, the fruit and vegetable conveying mechanism includes a conveying chain 224 and a driving mechanism, and a plurality of trays 221 are installed on the conveying chain 224 along the conveying direction for placing fruits and vegetables. The driving mechanism is connected to the conveying chain 224, and is used to drive the conveying chain 224 to drive the trays 221 to move, thereby realizing the conveying of fruits and vegetables, and the conveying can be intermittent conveying. In one embodiment, the driving mechanism includes a stepping motor 222 and a sprocket wheel set 223, the stepping motor 222 is connected to the sprocket wheel set 223 through a gear chain, the sprocket wheel set 223 is connected to the conveying chain 224 in a transmission manner, the stepping motor 222 is started, and the sprocket wheel set 223 converts the rotational motion of the stepping motor 222 into linear motion, thereby driving the conveying chain 224 and the tray 221 to move. In this embodiment, the running speed and the stop position of the conveyor belt can be accurately adjusted by the control system through the stepping motor 222. By adjusting the step angle of the stepper motor 222, the speed of the conveyor chain 224 can be precisely controlled, so that the tray 221 with fruits and vegetables is accurately placed on the plane grasped by the grasping mechanism to avoid the grasping mechanism grasping empty. In addition, the control system can also adjust the running direction of the conveyor belt according to different production requirements to achieve bidirectional or reverse conveying. The fruit and vegetable conveying mechanism can also be a circulating turntable.

[0027] The net sleeve conveying mechanism 400 is connected to the fixed frame 100, which can be directly connected or indirectly connected through a connecting piece. The net sleeve conveying mechanism 400 is arranged adjacent to the fruit and vegetable conveying mechanism, and is used to convey the net sleeve 700. The grabbing mechanism 300 is connected to the fixed frame 100, and is arranged above the fruit and vegetable conveying mechanism and the net sleeve conveying mechanism 400. The grabbing mechanism 300 can grab the fruits and vegetables on the fruit and vegetable conveying mechanism, and place them above the net sleeve conveying mechanism 400. Under the action of the net sleeve conveying mechanism 400, the net sleeve is set on the outer wall surface of the fruits and vegetables to realize automatic packaging of fruits and vegetables. Specifically, the net sleeve conveying mechanism 400 includes a conveying member, and a support platform is provided on the top of the conveying member. The grabbing mechanism 300 can place the fruits and vegetables on the support platform, and the net sleeve is set on the outer wall surface of the conveying member. The driving mechanism drives the conveying member to drive the net sleeve to move, and the net sleeve is set on the outer wall surface of the fruits and vegetables. In one embodiment, the grabbing mechanism 300 can be a manipulator. In another embodiment, the gripping mechanism 300 includes a plurality of clamping members, and the plurality of clamping members cooperate with each other to grip or stack fruits and vegetables. In yet another embodiment, the gripping mechanism 300 is an adsorbing member, and the suction force generated by the negative pressure adsorbs and moves the fruits and vegetables to the net sleeve, and the fruits and vegetables are automatically packaged, and the fruits and vegetables can be moved to the target position after completion. In the case where the gripping mechanism 300 is an adsorbing member, a through hole is provided on the bottom surface of the tray 221.

[0028] The net sleeve cutting mechanism 500 is connected to the fixed frame 100 and is arranged adjacent to the net sleeve conveying mechanism 400. After the net sleeve conveying mechanism 400 sets the net sleeve on the outer wall of the fruit and vegetable, the grasping mechanism 300 grasps the fruit and vegetable and moves upward for a certain distance, increases the distance between the fruit and vegetable and the net sleeve conveying mechanism 400, and increases the length of the net sleeves on the upper and lower sides of the fruit and vegetable; the net sleeve cutting mechanism 500 can move back and forth in the direction of approaching or moving away from the net sleeve (the net sleeve under the fruit and vegetable), and the net sleeve cutting mechanism 500 cuts the net sleeve 700. After cutting, the grasping mechanism 300 moves the packaged fruit and vegetable to the target position. In one embodiment, the net sleeve cutting mechanism 500 can be a cutting knife, and the net sleeve cutting mechanism 500 cuts the net sleeve 700 by the cutting knife. In another embodiment, the net sleeve cutting mechanism 500 is an electric heating wire 560, which cuts the net sleeve 700 by heating and melting.

[0029] The spherical fruit and vegetable net packaging equipment provided by the embodiment of the present invention is provided with a fruit and vegetable conveying mechanism, a net conveying mechanism 400, a grasping mechanism 300 and a net cutting mechanism 500 on a fixed frame 100. The grasping mechanism 300 can grasp the fruit and vegetable on the fruit and vegetable conveying mechanism and place it above the net conveying mechanism 400. The net is wrapped under the action of the net conveying mechanism 400. After the net is wrapped, the net cutting mechanism 500 can move back and forth in a direction close to or away from the net 700 to cut the net. No manual operation is required, and automatic packaging of fruits and vegetables can be achieved with high efficiency. Furthermore, by arranging the fruit and vegetable conveying mechanism and the net conveying mechanism 400 adjacent to each other, the net cutting mechanism 500 and the fruit and vegetable conveying mechanism adjacent to each other, and the grasping mechanism 300 above the fruit and vegetable conveying mechanism and the net conveying mechanism 400, the arrangement position is more reasonable, the rationality of the movement of the grasping mechanism 300 in the net packaging process is improved, the movement amount is reduced, the operation time is shortened, and the packaging efficiency is improved.

[0030] like Figure 1 As shown, there are two fruit and vegetable conveying mechanisms, namely, a first fruit and vegetable conveying mechanism 210 and a second fruit and vegetable conveying mechanism 220. The first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 are respectively arranged on both sides of the net conveying mechanism 400, and the net cutting mechanism is arranged adjacent to the net conveying mechanism 400. In one embodiment, the first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 are arranged adjacent to each other, and the net cutting mechanism 500 is arranged on the opposite side of the first fruit and vegetable conveying mechanism 210 or the second fruit and vegetable conveying mechanism 220. In another embodiment, the first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 are arranged opposite to each other, and the net cutting mechanism 500 is arranged between the two. The first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 can be the same or different. The moving distance of the first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 each time can be the distance between two adjacent fruits and vegetables on the mechanism, so as to facilitate the grasping mechanism 300 to grasp.

[0031] The grabbing mechanism 300 includes a first grabbing mechanism 310 and a second grabbing mechanism 320. The first grabbing mechanism 310 can grab the fruits and vegetables on the first fruit and vegetable conveying mechanism 210 and place them above the net conveying mechanism 400. Under the action of the net conveying mechanism 400, the net is put. The second grabbing mechanism 320 can grab the fruits and vegetables on the second fruit and vegetable conveying mechanism 220 and place them above the net conveying mechanism 400. Under the action of the net conveying mechanism 400, the net is put. In the embodiment of the present invention, the first grabbing mechanism 310 and the second grabbing mechanism 320 can respectively grab the fruits and vegetables on the corresponding fruit and vegetable conveying mechanism to achieve alternating netting and improve the netting efficiency. It should be noted that the first grabbing mechanism 310 and the second grabbing mechanism 320 can alternately place the fruits and vegetables above the net conveying mechanism 400 without interference. For example, when the first grabbing mechanism 310 is grabbing fruits and vegetables on the first fruit and vegetable conveying mechanism 210 , the second grabbing mechanism 320 can place the grabbed fruits and vegetables above the net conveying mechanism 400 , and vice versa.

[0032] Specifically, the first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 are installed in parallel to the fixed frame 100, and the first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 can both be transported in the first direction. The conveying direction of the first fruit and vegetable conveying mechanism 210 and the conveying direction of the second fruit and vegetable conveying mechanism 220 can be the same or opposite. The net sleeve conveying mechanism 400 is arranged between the first fruit and vegetable conveying mechanism 210 and the second conveying mechanism, and the first grabbing mechanism 310 and the second grabbing mechanism 320 are arranged on the fixed frame 100 at intervals, and can be slidably connected to the fixed frame 100 along the second direction. The first grabbing mechanism 310 can move to the first fruit and vegetable conveying mechanism 210 along the second direction, and after grabbing the fruits and vegetables, move in the reverse direction to the top of the net sleeve conveying mechanism 400 to be netted. Similarly, the second grabbing mechanism 320 can move to the second fruit and vegetable conveying mechanism 220 along the second direction, and after grabbing the fruits and vegetables, move in the reverse direction to the top of the net sleeve conveying mechanism 400 to be netted. The first direction is perpendicular to the second direction, and a plane formed by the first direction and the second direction is parallel to a plane where the tray is located.

[0033] In one embodiment, the net conveying mechanism 400 is arranged at the center position between the first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220, that is, there is a first vertical distance between the first fruit and vegetable conveying mechanism 210 and the net conveying mechanism 400, there is a second vertical distance between the second fruit and vegetable conveying mechanism 220 and the net conveying mechanism 400, and the first vertical distance is equal to the second vertical distance. The distance between the first grasping mechanism 310 and the second grasping mechanism 320, the first vertical distance and the second vertical distance are equal. The first grasping mechanism 310 and the second grasping mechanism 320 can alternately move the fruits and vegetables to the top of the net conveying mechanism 400 for netting. Specifically, the first grabbing mechanism 310 and the second grabbing mechanism 320 can move on the fixed frame 100 along the second direction. When the first grabbing mechanism 310 moves to the first fruit and vegetable conveying mechanism 210 to grab fruits and vegetables, the second grabbing mechanism 320 moves to the top of the net sleeve conveying mechanism 400 to put the net on. After the first grabbing mechanism 310 completes grabbing, the fruits and vegetables grabbed by the second grabbing mechanism 320 are netted and placed at the target position, such as being moved to the unloading conveying mechanism 610 adjacent to the net sleeve conveying mechanism 400 for transmission. After completion, the first grabbing mechanism 310 and the second grabbing mechanism 320 move in the opposite direction. The first grabbing mechanism 310 moves to the top of the net sleeve conveying mechanism 400 to put the net on, and the second grabbing mechanism 320 moves to the second fruit and vegetable conveying mechanism 220 to grab fruits and vegetables. After the second grabbing mechanism 320 completes grabbing, the fruits and vegetables grabbed by the first grabbing mechanism 310 are netted and placed at the target position, and a cycle is completed.

[0034] The embodiment of the present invention can alternately grab fruits and vegetables from the first fruit and vegetable conveying mechanism 210 and the second fruit and vegetable conveying mechanism 220 by controlling the alternating operation of the first grabbing mechanism 310 and the second fruit and vegetable conveying mechanism 220, and move them to the top of the net sleeve conveying mechanism 400 for netting. The alternating operation allows the net sleeve conveying mechanism 400 to continuously transmit and net, and the net sleeve cutting mechanism 500 can continuously cut the net sleeve 700, avoiding the uninterrupted working mode in traditional manual operation and improving the working efficiency of the netting operation. The entire packaging process is fully automated without manual intervention, thereby significantly reducing labor costs and improving the overall efficiency and automation level of the production line.

[0035] In one embodiment, the first gripping mechanism 310 and the second gripping mechanism 320 have the same structure. Figure 5As shown, a slide rail 110 is provided on the fixed frame 100, and the slide rail 110 is extended along the second direction, and the two ends of the slide rail 110 are respectively connected to the two ends of the fixed frame 100. The first grabbing mechanism 310 and the second grabbing mechanism 320 include a slider 321, a mounting member 322, a grabbing member 323, a first driving member 324 and a second driving member 325. The slider 321 is slidably connected to the slide rail 110, and the first driving member 324 is connected to the slider 321. The mounting member 322 is connected to the slide rail 110, the grabbing member 323 is slidably connected to the mounting member 322, and the second driving member 325 is connected to the grabbing member 323, driving the grabbing member 323 to move back and forth along the third direction to grab or place fruits and vegetables, and the first direction and the second direction are respectively perpendicular to the third direction.

[0036] In actual operation, the first driving member 324 drives the slider 321 to drive the mounting member 322 and the grabbing member 323 to move along the first direction on the slide rail 110. When the mounting member 324 moves to above the first fruit and vegetable conveying mechanism 210 or the second fruit and vegetable conveying mechanism 220, the second driving member 325 drives the grabbing member 323 to move along the third direction on the mounting member 322 toward the first fruit and vegetable conveying mechanism 210 or the second fruit and vegetable conveying mechanism 220 to grab fruits and vegetables. After grabbing, the grabbing member 323 moves in the opposite direction to increase the vertical distance between the first fruit and vegetable conveying mechanism 210 or the second fruit and vegetable conveying mechanism 220. The first driving member 324 drives the sliding block 321 to drive the mounting member 322 and the grabbing member 323 to move in the opposite direction on the slide rail 110 along the second direction. When it moves to the top of the mesh sleeve conveying mechanism 400, the second driving member 325 drives the grabbing member 323 to move in the third direction on the mounting member 322 toward the direction close to the mesh sleeve 700. After the mesh is wrapped, the second driving member 325 drives the grabbing member 323 to move in the opposite direction and move upward for a certain distance (set according to actual needs) to provide cutting space for the mesh sleeve cutting mechanism 500. The mesh sleeve cutting mechanism 500 moves back and forth toward the direction close to the mesh sleeve 700 to cut off the mesh sleeve. The second driving member 325 drives the grabbing member 323 to move in the opposite direction, leave the mesh sleeve conveying mechanism 400, and move it to the target workstation.

[0037] In order to adapt to different working conditions, the mounting member 322 can be slidably connected to the slider 321 along the second direction. Figure 5 As shown, a track 3211 is provided on the slider 321, and the track 3211 is extended along the second direction. The mounting member 322 can move along the extension direction of the track 3211 to adjust the position of the grabbing member 323 and achieve fine adjustment to adapt to different working conditions. For example, in the debugging stage, fine adjustment can be achieved by adjusting the position of the mounting member 322 on the slider 321. When the position of the net sleeve conveying mechanism 400 changes, the position of the mounting member 322 on the slider 321 can also be adjusted.

When the driving roller 423 and the driven roller 424 rotate, the driving roller group rotates synchronously, and the net 700 slides on the outer wall of the guide cylinder 410, which facilitates the spherical fruit and vegetable net. The driving motor includes a servo motor.

[0049] The net sleeve is a continuous belt-shaped structure. The net sleeve cutting mechanism 500 is arranged adjacent to the net sleeve conveying mechanism 400. After the net sleeve is placed on the fruits and vegetables, the grasping mechanism 300 grasps the fruits and vegetables and moves upward for a certain distance to provide cutting space for the net sleeve cutting mechanism 500.
