Description

Technical Field

[0001] This invention relates to the field of packaging bag bundling technology, and in particular to an automatic fruit bag bundling machine. Background Technology

[0002] Fruits are susceptible to damage from birds, pests, diseases, wind, rain, and sunlight as they approach maturity, resulting in reduced yields or variations in quality. To avoid losses and obtain high-quality, pollution-free fruit, fruit bagging technology has been developed, which necessitates the use of a large number of fruit bags.

[0003] Fruit bags are typically produced on fruit bagging machines, which can produce several bags at once according to set parameters and stack them together. To facilitate storage and transportation, the fruit bags need to be stacked, arranged, and tied in a certain quantity. Currently, this is generally done using a strapping machine. However, existing strapping machines have issues with the arrangement and tying of fruit bags, such as uneven arrangement and inadequate binding of rubber bands. This affects the efficiency and quality of the strapping process, leading to difficulties in stacking or the fruit bags coming apart during storage and transportation, causing inconvenience for subsequent use.

[0004] Therefore, it is necessary to propose an improvement to the automatic fruit bag tying machine to overcome the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art and provide an automatic fruit bag tying machine to automate the tying of fruit bags and improve tying efficiency and quality.

[0006] The technical solution of this invention is:

[0007] An automatic fruit bag tying machine includes a frame located at the outlet side of the fruit bag machine. The frame is equipped with a fruit bag transfer assembly, a fruit bag tying assembly, a rubber band feeder, a rubber band transfer assembly, a fruit bag unloading assembly, and a control assembly. The axis of the fruit bag tying assembly coincides with the axis of the fruit bag machine. The fruit bag transfer assembly is located on one side of the fruit bag tying assembly. The rubber band feeder, rubber band transfer assembly, and fruit bag unloading assembly are sequentially located on the other side of the fruit bag tying assembly. The outlet of the rubber band transfer assembly corresponds to that of the rubber band feeder. The fruit bag transfer assembly, fruit bag sorting assembly, fruit bag tying assembly, rubber band feeder, rubber band transfer assembly, and fruit bag unloading assembly are all electrically connected to the control assembly.

[0008] Using the above structure, the rubber band transfer component conveys the binding rubber bands from the rubber band feeder to the fruit bag binding component. The conveying is precise. The fruit bag binding component opens the rubber bands, and the fruit bag transfer component picks up the fruit bags prepared by the fruit bag machine and transports them to the fruit bag binding component. After clamping and positioning the fruit bags, the fruit bag binding component releases the rubber bands, which then retract and fit over the outside of the fruit bags, completing the binding operation. The fruit bag unloading component delivers the bound fruit bags to the unloading position. The entire assembly is located at the outlet end of the fruit bag machine. Through the transfer, binding, and unloading operations of the fruit bags after they are discharged from the fruit bag machine, combined with the feeding and transfer operations of the rubber bands, a fully automated process for fruit bag binding is achieved, reducing manual intervention, lowering labor costs, and improving the efficiency and quality of fruit bag binding.

[0034] To make the technical means, technical features, inventive purpose and technical effects of this invention easier to understand, the invention will be further described below with reference to specific illustrations.

[0035] Reference Figure 1 and Figure 2An automatic fruit bag tying machine includes a frame 2 located behind the outlet end of a fruit bag machine 1. A fruit bag receiving and positioning component 4 is installed at the outlet end of the fruit bag machine 1 to receive the fruit bags prepared by the machine, arrange them neatly, and record and verify the quantity of fruit bags according to set parameters. The frame 2 is equipped with a fruit bag sorting component 5, a fruit bag tying component 6, a fruit bag unloading component 8, a fruit bag transfer component 3, a rubber band feeder 11, and a rubber band transfer component 7. The sorting component 5 and the fruit bag binding component 6 are coaxially installed sequentially with the fruit bag receiving and positioning component 4. The fruit bag transfer component 3 is installed on one side of the fruit bag sorting component 5 and the fruit bag binding component 6, and its movement range can cover the fruit bag receiving and positioning component 4, the fruit bag sorting component 5, and the fruit bag binding component 6. It is used to grab fruit bags from the fruit bag receiving and positioning component 4 and convey them sequentially to the fruit bag sorting component 5 and the fruit bag binding component 6. The fruit bag sorting component 5 performs secondary sorting of the fruit bags to facilitate subsequent binding. The fruit bag binding assembly 6 is used to receive rubber bands and open and release them, binding the rubber bands onto the fruit bags. On the side of the frame 2 opposite to the fruit bag transfer assembly 3, a fruit bag unloading assembly 8 is installed, used to grab and transfer the bound fruit bags to the unloading position, completing the unloading operation. On the same side of the frame 2 as the fruit bag unloading assembly 8, a rubber band feeder 11 and a rubber band transfer assembly 7 are installed. The rubber band feeder 11 uses a vibratory feeder to vibrate and discharge the rubber bands one by one, facilitating the unloading process. The elastic band transfer component 7 is installed above the elastic band feeder 11 on the side near the fruit bag binding component 6. It is used to grab the elastic band and place it on the fruit bag binding component 6. A control component is also installed on the frame 2. The fruit bag receiving and positioning component 4, fruit bag sorting component 5, fruit bag transfer component 3, fruit bag binding component 6, elastic band transfer component 7, elastic band feeder 11 and fruit bag unloading component 8 are all electrically connected to the control component, and the control component controls each component to perform corresponding actions.

[0036] Reference Figure 3The fruit bag receiving and positioning assembly 4 includes a fruit bag guide plate 40, a fruit bag baffle 41, a fruit bag detector 42, and a grating ruler 43. There are two fruit bag guide plates 40, symmetrically installed near the fruit bag outlet of the fruit bag machine 1. The distance between the two guide plates 40 is adapted to the size of the fruit bag. The fruit bags produced by the fruit bag machine 1 first fall between the two guide plates 40 and are arranged neatly by them. The baffle 41 is connected to a baffle guide rail 44. The fruit bags are produced sequentially; the later-exiting bag pushes the earlier-exiting bag and simultaneously moves the baffle 41 on the baffle guide rail 44. The grating ruler 43 is installed on the outside of one of the baffle guide rails 44, and its reading head is connected to the baffle 41. The baffle 41 moves as it moves... During the process, the reading head of the grating ruler 43 moves synchronously along the scale grating of the grating ruler 43. During the movement, the displacement of the fruit bag baffle 41 is recorded. The fruit bag detector 42 is installed on both sides of the baffle guide rail 44. The fruit bag detector 42 adopts a through-beam detection switch. When the fruit bag machine 1 produces a fixed number of fruit bags (e.g., 100), the fruit bag machine 1 will automatically pop out 2 to 3 fruit bags. The fruit bag detector 42 can sense the popped-out fruit bags, thereby recording the number of fruit bags and matching it with the displacement data detected by the grating ruler 43. This guides the fruit bag transfer component 3 to grab the fruit bags. A limit detector 45 is installed at the end away from the fruit bag machine 1. The limit detector 45 is used to sense the moving position of the fruit bag baffle 41 to prevent the fruit bag baffle 41 from moving too much and falling off the baffle guide rail 44.

[0037] Reference Figure 4 The fruit bag transfer component 3 includes a servo module 30, a lifting slide, and a gripper unit. The servo module 30 is mounted on the frame 2 via a module bracket 31. The servo module 30's movement range spans above the fruit bag receiving and positioning component 4, the fruit bag sorting component 5, and the fruit bag binding component 6. It can drive the lifting slide and gripper unit to switch positions between the fruit bag receiving and positioning component 4, the fruit bag sorting component 5, and the fruit bag binding component 6, thus realizing the sequential transfer of fruit bag positions.

[0038] The lifting slide is installed on the slider of the servo module 30. The lifting slide includes a slide base plate 32, a first picking lifting cylinder 33, a second picking lifting cylinder 34, a transition plate 35, and a gripper bracket 36. The slide base plate 32 is connected to the slider of the servo module 30. The first picking lifting cylinder 33 is fixedly connected to the upper part of the slide base plate 32. A linear guide rail is installed on the slide base plate 32. The transition plate 35 is connected to the slider of the linear guide rail and is connected to the extended end of the first picking lifting cylinder 33. The first picking lifting cylinder 33 drives the transition plate 35 to slide up and down relative to the slide base plate 32. The second picking lifting cylinder 34 is installed on the upper part of the transition plate 35. A linear guide rail is installed on the transition plate 35. The gripper bracket 36 is connected to the slider of the linear guide rail and is connected to the extended end of the second picking lifting cylinder 34. The second picking lifting cylinder 34 drives the gripper bracket 36 to move up and down relative to the transition plate 35.

[0039] The gripper unit is installed on the lifting slide. The gripper unit includes a fixed gripper 37, a gripper cylinder 38, and a movable gripper 39. The fixed gripper 37 is fixedly connected to one side of the bottom of the gripper bracket 36, and the gripper cylinder 38 is connected to the other side of the bottom of the gripper bracket 36. A linear guide rail is installed on the gripper bracket 36. The movable gripper 39 is connected to the slider of the linear guide rail and to the extended end of the gripper cylinder 38. The gripper cylinder 38 drives the movable gripper 39 to move laterally relative to the gripper bracket 36, moving closer to and away from the fixed gripper 37 to clamp and release the fruit bag. The lifting slide drives the gripper unit to rise and fall. Two stacked cylinders are used to control two material picking positions, which has high position control accuracy. The gripper unit realizes the gripping of the fruit bag.

[0040] Using the above structure, the servo module 30 drives the lifting slide and gripper unit to switch positions between the fruit bag receiving and positioning component 4, the fruit bag sorting component 5, and the fruit bag binding component 6, thereby transferring the position of the fruit bags. The first picking lifting cylinder 33 drives the adapter plate 35, the second picking lifting cylinder 34, the gripper bracket 36, and the gripper unit to descend, causing the fixed gripper 37 to descend above the fruit bag. The second picking lifting cylinder 34 is activated, and the fixed gripper 37 is inserted between the popped-out fruit bag and the regular fruit bag. The first gripper cylinder 38 is activated, driving the moving gripper 39 to approach the fixed gripper 37 and clamp the set number of fruit bags. The first lifting cylinder and the second picking lifting cylinder 34 are activated simultaneously to lift the clamped fruit bags. The servo module 30 is activated to move and transport the fruit bags to the fruit bag sorting component 5.

[0041] Reference Figure 5 and Figure 6The fruit bag sorting assembly 5 includes a sorting mounting plate 51, a bottom sorting cylinder 52, front and rear sorting cylinders 53, and left and right sorting cylinders 54. The sorting mounting plate 51 is connected to the frame 2. A square through hole is machined in the center of the sorting mounting plate 51. The bottom sorting cylinder 52 is installed below the sorting mounting plate 51. A support plate is connected to the extended end of the bottom sorting cylinder 52. The support plate can be driven by the bottom sorting cylinder 52 to extend into the square through hole. There are two front and rear sorting cylinders 53 and two left and right sorting cylinders 54. The two front and rear sorting cylinders 53 and the two left and right sorting cylinders 54 are respectively installed on both sides of the top of the sorting mounting plate 51. The front and rear sorting cylinders 53 on the same side are connected to the bottom sorting cylinders 54. The installation directions of the front and rear sorting cylinders 53 and 54 are perpendicular to each other. The front and rear sorting push plates 55 are connected to the extended ends of the front and rear sorting cylinders 53, and the left and right sorting push plates 56 are connected to the extended ends of the left and right sorting cylinders 54. When the bottom sorting cylinder 52 is activated, the tray extends into the square through hole. The fruit bag transfer component 3 picks up a set number of fruit bags and places them on the tray, so that the fruit bags are located in the cavity formed by the front and rear sorting push plates 55 and the left and right sorting push plates 56. The front and rear sorting push plates 55 and the left and right sorting push plates 56 move in sequence to sort the fruit bags inside, making the fruit bags more neatly arranged, so that the fruit bag transfer component 3 can pick them up again, thereby improving the subsequent binding quality.

[0042] Reference Figures 7-10 The fruit bag binding assembly 6 includes a flipping cylinder 60, a flipping plate 61, a fruit bag clamping cylinder 62, and elastic band loosening units. The fixed end of the flipping cylinder 60 is hinged to the frame 2, and the extended end of the flipping cylinder 60 is hinged to the flipping plate 61. The flipping plate 61 can be flipped 90° on the flipping bracket 63 by the flipping cylinder 60, allowing the flipping plate 61 to switch between a horizontal and an upright state. The flipping plate 61 is processed into a square plate with a U-shape, and the hole in the middle can be used to place the fruit bag. There are two fruit bag clamping cylinders 62, which are symmetrically installed on both sides of the flipping plate 61 to clamp the fruit bag. There are four elastic band loosening units, which are symmetrically installed in pairs. Installed at the four corners of the flip plate 61, all facing the center of the flip plate 61, it is used to realize the opening and closing of the rubber band. The flip plate 61 between the two rubber band loosening units is equipped with a rubber band presence detection switch 64. In the initial position, the flip cylinder 60 drives the flip plate 61 to an upright state, which makes it easy for the rubber band transfer assembly 7 to place the rubber band on the rubber band loosening unit. When the rubber band opening action is performed, the rubber band presence detection switch 64 can detect whether the rubber band has been opened. When the rubber band is detected to be opened, the flip cylinder 60 drives the flip plate 61 to flip to a horizontal state. The fruit bag transfer assembly 3 grabs the fruit bag after secondary sorting and places it between the two fruit bag clamping cylinders 62, which clamp the fruit bag.

[0043] The elastic band tensioning unit includes an elastic band tensioning cylinder 65 and an elastic band release cylinder 66. The elastic band tensioning cylinder 65 is installed at one corner of the top of the flip plate 61. A tensioning block 67 is connected to the extended end of the elastic band tensioning cylinder 65. A tensioning rod 68 is slidably installed inside the tensioning block 67. A spring 69 is fitted on the tensioning rod 68. Under the elastic force of the spring 69, the upper end of the tensioning rod 68 can extend to the outside of the tensioning block 67 to catch the elastic band and pull the elastic band open under the action of the elastic band tensioning cylinder. The elastic band release cylinder 66 is installed at the bottom of the flip plate 61 and is located below the elastic band tensioning cylinder 65. A locking block 610 is connected to the extended end of the elastic band release cylinder 66. A U-shaped locking groove is machined on the locking block 610. 611, the opening of the U-shaped slot 611 faces the direction in which the elastic band tensioning cylinder 65 extends. When the elastic band tensioning cylinder 65 drives the tensioning rod 68 to extend forward, the elastic band release cylinder 66 drives the locking block 610 to extend upward. When the elastic band tensioning cylinder 65 drives the tensioning rod 68 to reset, the lower end of the tensioning rod 68 can be locked in the U-shaped slot 611. When the fruit bag clamping cylinder 62 clamps the fruit bag, the elastic band release cylinder 66 resets downward, pulling the tensioning rod 68 to overcome the elastic force of the spring 69 and move downward. The elastic band is released from the tensioning rod 68 and tied to the fruit bag. After tying, the flipping cylinder 60 is activated again, flipping the flipping plate 61 from 90° horizontal to upright, waiting for the fruit bag unloading assembly 8 to unload the fruit bag.

[0044] Reference Figure 11 The rubber band transfer assembly 7 includes a first transfer cylinder 70, a second transfer cylinder 71, a rubber band lifting cylinder 72, and a rubber band gripper 73. The first transfer cylinder 70 is mounted on the frame 2 via a column 74. The extended end of the first transfer cylinder 70 is connected to a first mounting plate 75, which is connected to a linear guide rail mounted on the column 74. The second transfer cylinder 71 is mounted on the first mounting plate 75, and the extended end of the second transfer cylinder 71 is connected to a second mounting plate 76, which is connected to a linear guide rail mounted on the first mounting plate 75. The second rubber band lifting cylinder 72 is mounted on the second mounting plate 76, and the rubber band gripper 73 is connected to the extended end of the second rubber band lifting cylinder 72.

[0045] When transfer cylinder 1 70, transfer cylinder 2 71, and the up-and-down rubber band picking cylinder 72 are all in their initial positions, the rubber band gripper 73 is located directly above the outlet of the rubber band feeder 11. The rubber band feeder 11 vibrates a rubber band to the outlet. The up-and-down rubber band picking cylinder 72 moves, causing the rubber band gripper 73 to descend and clamp the rubber band. The up-and-down rubber band picking cylinder 72 resets, and transfer cylinder 1 70 extends forward to transport the rubber band to the fruit bag binding assembly 6. After transfer cylinder 1 70 delivers the rubber band into place, transfer cylinder 2 71 moves, moving the rubber band towards the tensioning rods 68 so that the rubber band can be fitted onto the four tensioning rods 68. The rubber band gripper 73 releases its clamp on the rubber band. After the rubber band is placed in place, transfer cylinder 2 71 and transfer cylinder 1 70 reset sequentially and enter the next cycle. The rubber band tensioning cylinder 65 performs the action of pulling the rubber band open.

[0046] Reference Figure 12 The fruit bag unloading assembly 8 includes an unloading bracket 80, a rotating swing arm 81, a second tilting cylinder 82, and a second gripper cylinder 83.

[0048] Working principle of this invention:

[0049] Fruit bagging machine 1 produces fruit bags, which are then neatly arranged by fruit bag guide plate 40. The fruit bags are produced sequentially, pushing fruit bag baffle 41 to move on baffle guide rail 44. During the movement, the displacement is recorded by grating ruler 43. For every fixed number of fruit bags produced, fruit bagging machine 1 automatically ejects 2 to 3 fruit bags for counting. Fruit bag detector 42 senses the ejected fruit bags to record the number of fruit bags, and at the same time, matches the data from grating ruler 43 to guide fruit bag transfer component 3 to remove the fruit bags.

[0050] The servo module 30 moves to the position of the fruit bag receiving and positioning component 4 according to the instruction issued by the PLC. The first picking lifting cylinder 33 and the second picking lifting cylinder 34 are activated, the gripper unit descends to the position, the first gripper cylinder 38 is activated, and the moving gripper 39 is pushed to clamp the fruit bag. The first picking lifting cylinder 33 and the second picking lifting cylinder 34 are reset, and the servo module 30 moves to the position of the fruit bag sorting component 5.

[0051] When the material lifting cylinder 1 33 and the material lifting cylinder 2 34 are activated, the fruit bag is placed into the fruit bag sorting component 5. The material lifting cylinder 1 33 and the material lifting cylinder 2 34 are reset. The bottom sorting cylinder 52, the front and rear sorting cylinder 53 and the left and right sorting cylinder 54 perform corresponding actions according to the settings. After the actions are completed, the material lifting cylinder 1 33 and the material lifting cylinder 2 34 are activated at the same time. The gripper cylinder 1 38 clamps the fruit bag again and removes the fruit bag sorting component 5.

[0052] The flipping cylinder 60 moves to put the flipping plate 61 in an upright position. The rubber band picking cylinder 72 and the rubber band clamp 73 move in sequence to clamp the rubber band from the rubber band feeder 11. The flipping cylinder 72 returns to its original position. The transfer cylinder 70 and the transfer cylinder 71 move in sequence to send the rubber band to the fruit bag binding assembly 6. The rubber band clamp 73 opens to hang the rubber band on the tension rod 68. The transfer cylinder 71 and the transfer cylinder 70 move in sequence to reset. The four rubber band tensioning cylinders 65 move to tighten the rubber band. The rubber band presence detection switch 64 detects that a rubber band has been pulled open. The flipping cylinder 60 flips the flipping plate 61 to flatten it.

[0053] Servo module 30 transfers the fruit bag to the fruit bag binding component 6, places the fruit bag in place, fruit bag clamping cylinder 62 clamps the fruit bag, gripper cylinder 38 releases the fruit bag, and fruit bag transfer component 3 resets.

[0054] When the rubber band release cylinder 66 is activated, the rubber band is released from the tension rod 68 and tied to the fruit bag. The flipping cylinder 60 flips the flipping plate 61 to an upright position.

[0055] The flipping cylinder 2 82 moves, pushing the rotating arm 81 to rotate around the rotating bearing seat, rotating the gripper cylinder 2 83 to the position of the rubber band binding component, the gripper cylinder 2 83 clamps the fruit bag, and at the same time the fruit bag clamping cylinder 62 returns to its original position, the flipping cylinder 2 82 resets and sends the fruit bag to the unloading position, the gripper cylinder 2 83 resets to complete the unloading of the fruit bag, and the process ends.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention. All equivalent changes and modifications made in accordance with the scope of the claims of this invention should fall within the technical scope of this invention.
