DETAILED DESCRIPTION

[0019] The following will be combined with specific embodiments and attached Figure 1-5 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the preferred embodiments of the utility model, not all of the embodiments. Those skilled in the art can make similar modifications without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] The utility model is aimed at the secondary ice packing and packaging operation of various vegetables, especially broccoli, which have been frozen and output from a vegetable ice hanging machine.

[0021] The utility model provides a broccoli packing line (such as Figure 1As shown), it includes an ice packing mechanism, a material distribution mechanism, a weighing mechanism, a carton tape sealing machine 4, a palletizing robot 5, a single-layer palletizing component, a discharging station, and a controller. The ice packing mechanism includes a conveyor belt 11, a guide groove 12, and a spray mechanism. The conveyor belt 11 adopts a food-grade conveyor belt to improve the safety of vegetables. The conveyor belt 11 includes a high-level conveying section 111, a middle-level conveying section 112, and a low-level conveying section 113. Specifically, the conveyor belt 11 is arranged on a support frame 14. The specific manner of arranging the conveyor belt 11 on the support frame 14 and the technical scheme for realizing its operation are all known technical schemes in the art, so they are not described in detail here; the frozen materials enter from the feeding end of the high-level conveying section 111 and pass through the high-level conveying section 112 in sequence. 11, the middle conveying section 112 and the low conveying section 113 enter the guide groove 12, the spray mechanism includes a plurality of spray heads 13, the spray mechanism is also a known technical product in the art, and its main working principle is to convey high-pressure water to the spray head 13, and after the high-pressure water is output from the spray head 13, water mist can be formed. A plurality of spray heads 13 are arranged above the high conveying section 111, the middle conveying section 112 and the low conveying section 113. The horizontal height of the high conveying belt 111 is higher than the horizontal height of the middle conveying section 112, and the horizontal height of the middle conveying section 112 is higher than the height of the low conveying section 113. When the broccoli enters the middle conveying section 112 from the high conveying belt 111, the broccoli can be transported to the middle conveying section 112 due to the height difference. Once the broccoli enters the low-position conveying section 113 from the middle conveying section 112, the broccoli is subjected to a secondary posture adjustment due to the height difference. During the two posture adjustments of the broccoli, the spray head 13 always performs a spraying operation, so that the entire outer surface of the broccoli can be attached with water droplets. Because the outer surface of the broccoli is in an ice-hanging state, when the water droplets adhere to the surface of the broccoli, the water droplets freeze to form an ice layer, thereby realizing a secondary ice-wrapping operation on the surface of the broccoli. The ice-wrapping quality of the broccoli surface is good, thereby improving the protection of the flower buds. In the subsequent packing process of the broccoli, the number of flower buds that fall can be effectively reduced, thereby improving the packing quality of the broccoli; the material flows into the material distribution channel 12 and enters the material distribution channel 12. In the mechanism, the weighing mechanism includes two groups of weighing components, each group of the weighing components includes a weighing tray 31. In actual application, the carton packaging broccoli is placed on the weighing tray 31, and the weighing components are used to achieve specific weighing of the broccoli. When the weight of the broccoli in the carton reaches the set required weight, the carton is taken down from the weighing tray 31, and then the next broccoli packing weighing process is continued. The material dividing mechanism is used to intermittently convey materials to the cartons on the two weighing trays 31 in turn. The carton tape sealing machine 4 is used to achieve the sealing of cartons containing a certain amount of materials. The carton tape sealing machine 4 is a mature technical product on the existing market, so the working principle and structure of the carton tape sealing machine 4 are not described in detail here.The palletizing robot 5 is used to stack several cartons output from the discharge end of the carton tape sealing machine 4 in a single layer on the single layer palletizing station. The palletizing robot 5 is a mature technology product on the market, so the structure and working principle of the palletizing robot 5 are not described in detail here. The single layer palletizing station is used to stack a certain number of cartons stacked in a single layer on the discharge station. In actual application, the single layer palletizing station stacks the single layer stacked cartons layer by layer on the discharge station. When the cartons on the discharge station are stacked to a certain height, the forklift is used to move the cartons from the discharge station, and then the single layer palletizing station continues to stack. The orderly cooperation of the palletizer robot 5, the single layer palletizing component and the discharge station can realize the automatic palletizing of cartons, thereby reducing the labor intensity of manual labor. ;

[0022] On the basis of the above embodiment, in order to improve the efficiency of ice packing of broccoli, the material distribution mechanism can adopt the following specific implementation mode: the material distribution mechanism includes a material distribution hopper 21, and the material distribution hopper 21 includes an inlet 211 and two outlets 212. The lower part of the outlet of the guide groove 12 is opposite to the middle part of the material distribution port 211, that is, the material flowing out of the guide groove 12 can fall into the middle position of the inlet 211. Two material distribution partitions 22 are arranged inside the inlet 211. The two material distribution partitions 22 are arranged opposite to each other, and the upper part of each material distribution partition 22 is hingedly connected to the inner side wall of the inlet 211. A material distribution cylinder 23 corresponding to the material distribution partition 22 is arranged on the material distribution hopper 21, and the telescopic end of the material distribution cylinder 23 is hingedly connected to the rear side wall of the corresponding material distribution partition 22. The fixed end of the material distribution cylinder 23 is connected to the upper part of the material distribution hopper 21. A bracket 213 is hingedly connected, and when the dividing cylinder 23 performs telescopic movement, the corresponding dividing partition 22 can swing in the feeding port 211, and when the telescopic rod of the dividing cylinder 23 is extended to the set position, the corresponding dividing partition 22 realizes the separation of the feeding port 211 and the corresponding discharging port 212, so that the broccoli cannot flow out from the corresponding discharging port 212. The discharging port 212 corresponds to the corresponding weighing tray 31 up and down, and the controller can control the operation of the dividing cylinder 23. In actual application, the controller realizes the intermittent operation of the two dividing cylinders 23, and then realizes the gap discharging of the two discharging ports 212, so as to facilitate the manual handling and folding operations of the cartons for packing and weighing. The cartons after the folding operation are placed at the feeding end of the carton tape sealing machine 4, so as to facilitate the automatic sealing operation of the carton tape sealing machine 4.

[0023] On the basis of the above embodiment, the specific implementation of the weighing assembly is as follows: each group of the weighing assembly also includes a weighing lever 32, a counterweight 33, and a fine-tuning mechanism, the weighing lever 32 is hingedly arranged on a first support platform 36, the weighing tray 31 and the counterweight 33 are relatively distributed at both ends of the weighing lever 32, and the distance from the center position of the weighing tray 31 to the fulcrum position of the weighing lever 32 is equal to the distance from the center position of the counterweight 33 to the fulcrum position of the weighing lever 32. In actual application, the weight of the counterweight 33 is pre-calibrated according to the total weight of the carton and the broccoli to be packaged in the carton. When the counterweight 33 After the weight is calibrated, the lever principle is used to calibrate the broccoli packing quality. This quality calibration method is simple and reliable, and is not prone to problems. The fine-tuning mechanism includes a threaded rod 341 and an adjustment block 342. The threaded rod 341 is fixedly connected to the weighing lever 32, and the threaded rod 341 is located directly below the weighing lever 32. The adjustment block 342 is sleeved on the threaded rod 341. During the calibration and leveling process of the counterweight block 33 and the set mass of the broccoli, in order to improve the balance accuracy, after the mass of the counterweight block 33 is determined, the position of the adjustment block 342 on the threaded rod 341 can be moved to achieve the counterweight at both ends of the weighing lever 32. In order to facilitate the fixing of the position of the adjusting block 342 on the threaded rod 341, a pressing bolt can be set on the adjusting block 342, and the positioning of the adjusting block 342 is achieved by the pressing effect of the pressing bolt on the threaded rod 341; in order to facilitate the controller to obtain the weighing end signal, so that the controller can realize the intermittent coordinated movement of the two material distribution cylinders 23, a travel switch 35 is set below the bearing part of the weighing lever 32 that carries the weighing tray 31, and the travel switch 35 is electrically connected to the controller. During the weighing process, when the end of the weighing lever 32 carrying the broccoli begins to swing downward, , it means that the broccoli in the carton has reached the packaging weight requirement. At this time, as the end of the weighing lever 32 carrying the broccoli continues to move downward, it will touch the travel switch 35 below it. After the travel switch 35 is activated, the controller obtains the corresponding control signal. According to the control signal, the controller starts the corresponding material dividing cylinder 23, so that the material dividing partition 22 blocks the corresponding material discharging port 212 from discharging. After the corresponding material discharging port 212 no longer discharges material, the staff can move the carton from the weighing tray 31 to the carton tape sealing machine 4, and then put the next carton on the weighing tray 31, so as to wait for the next loading. The two material dividing partitions 22 act intermittently, and then the two material discharging ports 212 discharge intermittently, so that the staff has the time to pre-fold the upper cardboard of the carton and move the carton to the carton tape sealing machine 4. At the same time, it can also ensure that the conveyor belt 11 continuously outputs materials.

[0024] On the basis of the above embodiment, the specific implementation of the single-layer palletizing component is as follows: the single-layer palletizing component includes a second support platform 61, a lifting plate 62, a horizontal moving plate 63 and a blocking component, the lifting plate 62 is arranged on the second support platform 61, and a lifting cylinder 611 is arranged on the second support platform 61 to realize the lifting and lowering movement of the lifting plate 62. In order to ensure the stable lifting and lowering of the lifting plate 62, four guide rods 612 are arranged around the bottom of the lifting plate 62, and the guide rods 612 run through the second support platform 61. The horizontal moving plate 63 is arranged on the lifting plate 62. Specifically, both sides of the horizontal moving plate 63 are clamped in the grooves arranged on the lifting plate 62. The clamping of the horizontal moving plate 63 by the two grooves realizes the up and down displacement movement of the horizontal moving plate 63 relative to the lifting plate 62. The first cylinder 631 arranged on the lifting plate 62 is used to realize the left and right movement of the horizontal moving plate 63 on the lifting plate 62. The blocking component is arranged on the lifting plate 62. On the upper right side of the lifting plate 62, the blocking assembly includes a ∩-shaped frame 641, a blocking plate 642, and a blocking cylinder 643. Both ends of the ∩-shaped frame 641 are fixedly connected to the lifting plate 62. The blocking cylinder 643 is invertedly arranged on the ∩-shaped frame 641. The upper part of the blocking plate 642 is fixedly connected to the bottom of the telescopic rod of the blocking cylinder 643. The blocking plate 642 can be moved up and down by the blocking cylinder 643. The horizontal moving plate 63 is located on the blocking plate 64 2, the controller controls the operation of the first cylinder 611, the lifting cylinder 631 and the blocking cylinder 643. In actual application, the palletizing robot 5 stacks the cartons on the carton tape sealing machine 4 one by one in a single layer on the horizontal moving plate 63 according to the set program. When the number of cartons reaches the requirement, the palletizing robot 5 stops stacking. At this time, the lifting cylinder 611 and the first cylinder 631 can be used to cooperate to move the cartons on the horizontal moving plate 63 to the designated position of the discharge station.Furthermore, the specific implementation of the discharging station is as follows: the discharging station is arranged on the right side of the horizontal moving plate 63, and the discharging station includes a third support platform 71, a carrying plate 72, and a second cylinder 73. The third support platform 71 is in a front-to-back placement state, and the carrying plate 72 is arranged on the third support platform 71. The second cylinder 73 is used to realize the front-to-back horizontal movement of the carrying plate 72 on the third support platform 71. Two discharging stations are arranged on the carrying plate 72, and a forklift pallet 721 is placed on each of the discharging stations. The controller controls the operation of the second cylinder 73. In actual application, Driven by the second cylinder 73, one of the material discharge stations is located on the right side of the horizontal movable plate 73. When the lifting plate 62 is lifted to the set height, the lifting plate 62 remains stationary. Then, the first cylinder 631 pushes the horizontal movable plate 63 to start moving toward the material discharge station. When the horizontal movable plate 63 moves to the set position, it stops moving. Then, the blocking cylinder 643 is started to move the blocking plate 642 down to the set blocking position. After the blocking plate 642 moves down to the set blocking position, the horizontal movable plate 63 starts to retract. In the process of the horizontal movable plate 63 retracting, the blocking effect of the blocking plate 642 causes the horizontal movable plate 63 to move downward. The single-layer stacked cartons will not move synchronously with the horizontal moving plate 63. When the horizontal moving plate 63 is fully retracted, the single-layer stacked cartons are finally placed at the unloading station. Then, the lifting plate 62 returns to the initial working position and enters the next single-layer stacking process. The single-layer stacking station repeats the above actions to achieve stacking of cartons on the unloading station layer by layer. When the cartons on a unloading station are stacked to a specified height, the second cylinder 73 is used to move another vacant unloading station to the right side of the horizontal moving plate 63, so that the single-layer stacking station can repeat the stacking work at this unloading station. When the material station is stacking, the staff can use a forklift to move the carton from another material discharging station, and then put a forklift pallet 721 on this material discharging station, so that the material discharging station enters the preparatory stacking state. The intermittent movement of the two material discharging stations facilitates the synchronization of stacking and transportation, and improves the stacking efficiency. Further, in order to improve the placement stability of the carton on the material discharging station, four auxiliary columns 722 are arranged around each of the material discharging stations, and the carton is located in a square three-dimensional area surrounded by the four auxiliary columns 722. The limit of the auxiliary columns 722 effectively prevents the carton stack from tilting. The lifting height setting of the lifting plate 62 can be adapted according to the height of the carton, so as to ensure that the horizontal moving plate 73 can move to the top of the existing carton layer on the material discharging station every time, so as to facilitate the final stacking of the carton on the horizontal moving plate 73 on the material discharging station.

[0025] In practical applications, in order to prevent the water mist from floating around during the spraying process, the ice packing mechanism may further include an isolation box, the conveyor belt 11 and the nozzle 13 are both located in the isolation box, and the discharge end of the guide trough 12 is located outside the isolation box.

[0026] In the actual working process, the frozen broccoli output from the vegetable ice machine directly enters the conveyor belt 11, and the nozzle 13 continues to spray. A staff member is arranged next to each group of weighing components. The staff member places the carton on the weighing tray 31, removes the carton from the weighing tray 31 and places it on the carton tape sealing machine 4, and pre-folds the upper cardboard of the carton. A staff member is arranged at the discharging station so that the staff member can use a forklift to carry the stacked carton from the corresponding unloading station. In the present utility model, "left" and "right" are relative positions used for the convenience of describing the position relationship, and therefore cannot be understood as an absolute position to limit the scope of protection.

[0027] Except for the technical features described in the specification, all other technical features are known technologies to those skilled in the art.

[0028] The above description in combination with the accompanying drawings has detailed the preferred implementation modes and embodiments of the utility model, but the utility model is not limited to the above implementation modes and embodiments. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the concept of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
