Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, and in particular relates to a continuous bagging packaging equipment for industrial products. Background Technology

[0002] In industrial production, large items, such as assembled circuit boards or assembled mechanical kits that form a certain function or connection, are generally packaged in plastic bags, vacuum-sealed, and then stored for later use or loaded onto trucks for sale. The actions of packaging large items in plastic bags, vacuum-sealing, and sealing are mostly done manually. The disadvantages of this are: first, the operation time is long and the production efficiency is low; second, the manual involvement in the packaging process can easily cause damage or contamination to the items; and third, the packaging or sealing openings are not standardized and uniform, resulting in poor quality of packaged products. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous bagging packaging equipment for industrial products that automatically packs large industrial assemblies or finished products into plastic bags and seals them using a vacuum machine, so as to improve production efficiency, prevent human error in packaging, and achieve standardized packaging.

[0004] The objective of this invention is achieved as follows:

[0005] An industrial continuous bagging packaging device includes a first worktable. A transverse conveying mechanism is located on one side of the first worktable, and a vacuum feeding mechanism and a plastic bag stacking position are located on the other side. The conveying mechanism has a bagging position and a sealing position. A first opening mechanism and an assembly feeding mechanism are located on one side of the bagging position, and a second opening mechanism, a flattening mechanism, and a sealing mechanism are located on one side of the sealing position. The bagging position is located next to the vacuum feeding mechanism. Under the program control of the controller: the vacuum feeding mechanism conveys plastic bags from the plastic bag stacking position to the bagging position; the first opening mechanism opens the bag opening of the plastic bags conveyed to the bagging position; and the assembly feeding mechanism feeds the assembled parts... The assembly containing the plastic bag is conveyed to the second opening mechanism, which opens the bag opening. The flattening mechanism flattens the bag opening, and the sealing mechanism electrically heats and seals the bag opening. The bag is then conveyed forward. The first and second opening mechanisms respectively use the first and second lower vacuum suction cups on the lower side to adhere to the lower surface of the bag opening, and the first and second upper vacuum suction cups on the upper side to adhere to the upper surface of the bag opening. By controlling the first and second upper vacuum suction cups on the upper side to move upward, the bag opening can be opened.

[0006] As a further optimization of the above technical solution, the vacuum feeding mechanism includes a first slider that slides along a first slide rail horizontally arranged on a first support and is driven by a power source; a first mounting frame that slides along a second slide rail vertically arranged on the first slider and is driven by a power source; and a third vacuum suction cup arrayed with multiple rows and columns for adsorbing plastic bags on the first mounting frame. The third vacuum suction cup is connected in sequence to a solenoid valve, a vacuum tank, and a vacuum pump through a conduit. The opening and closing of the solenoid valve is controlled by a controller to control whether the third vacuum suction cup adsorbs or does not adsorb the upper surface of the plastic bag.

[0007] As a further optimization of the above technical solution, an assembly guide mechanism is provided at the outlet of the assembly feeding mechanism. The assembly guide mechanism consists of two vertically arranged movable plates that are driven by a first conveyor belt to move closer or further apart along the first transverse slide on the upper crossbeam of the assembly feeding mechanism. A lower guide block is provided at the lower part of the movable plates, and an upper guide block that is driven to move up and down is provided on the upper vertical slide.

[0008] As a further optimization of the above technical solution, the first supporting mechanism includes a second mounting frame vertically mounted on the upper crossbeam of the assembly feeding mechanism, driven by a second cylinder to move up and down. The lower part of the second mounting frame is provided with two or more first upper vacuum suction cups with downward suction ports. The first worktable below the first upper vacuum suction cups is provided with two or more first lower vacuum suction cups with upward suction ports. The first lower vacuum suction cups are staggered from the first upper vacuum suction cups. The second supporting mechanism is a third mounting frame mounted on a second bracket on one side of the sealing position, driven by a sealing cylinder to move up and down. The lower part of the third mounting frame is provided with two or more second upper vacuum suction cups with downward suction ports. The first worktable below the second upper vacuum suction cups is provided with two or more second lower vacuum suction cups with upward suction ports. The second lower vacuum suction cups are staggered from the second upper vacuum suction cups. The second upper vacuum suction cups and the second lower vacuum suction cups are all connected to a solenoid valve, a vacuum tank, and a vacuum pump in sequence through conduits. The action of the solenoid valve is controlled by the controller.

[0009] As a further optimization of the above technical solution, the assembly feeding mechanism includes a second conveyor belt on both sides of the frame, driven by a power source. Guard plates and / or railings are respectively installed on the frame outside the two second conveyor belts. A bagging mechanism is installed between the two second conveyor belts. The bagging mechanism includes a second slider driven by a power source sliding along a third slide rail on a longitudinal third slide rail. A cantilever support plate driven by a third cylinder slides along a fourth slide rail vertically mounted on the second slider. The bottom of the cantilever support plate rests on a roller of a third bracket at the end of the third slide rail. The action of the third cylinder causes the cantilever support plate to rise, thereby causing the assembly on the second conveyor belt to detach from the second conveyor belt. The action of the second slider driven by the power source can feed the assembly on the cantilever support plate into a plastic bag.

[0010] As a further optimization of the above technical solution, the flattening mechanism is provided with a third slider that is driven to slide along the longitudinal slide on the first worktable. The third slider is provided with two support plates that extend toward the conveying mechanism on the second transverse slide. The two support plates are driven by a third conveyor belt to move closer to each other or further away from each other along the second transverse slide. When the two support plates move longitudinally to insert into the opening of the plastic bag and then move laterally away from each other, the opening of the plastic bag will be flattened.

[0011] As a further optimization of the above technical solution, the middle of the second transverse slide is provided with two or more vacuum suction flat tubes that extend toward the conveying mechanism and are connected in sequence to the solenoid valve, vacuum tank and vacuum pump through conduits. The front end of the vacuum suction flat tube is provided with a suction port, and the solenoid valve is controlled by the controller.

[0012] As a further optimization of the above technical solution, the sealing mechanism includes a second bracket and a fifth cylinder and a first lower sealing plate respectively disposed on the upper side and the lower side of the second bracket. The first upper sealing plate is fixed to the lower side of the fifth cylinder. The upper sealing plate, which is heated by electricity, is driven downward by the fifth cylinder to cooperate with the first lower sealing plate, which is heated by electricity, to press the opening of the plastic bag and stay for a set time to achieve heat sealing of the plastic bag opening.

[0013] As a further optimization of the above technical solution, the end of the conveying mechanism is provided with a longitudinal conveying mechanism for the sealed plastic bag. The sealing component conveying mechanism includes lifting plates that are spaced apart on the second worktable and driven to rise and fall by a sixth cylinder. Multiple synchronously rotating transmission rollers driven by power are provided on the lifting plates. Two or more longitudinally driven fourth conveyor belts are provided between adjacent lifting plates and on the outside of the lifting plates. After the lifting plates are lowered, the upper surface of the fourth conveyor belt is higher than the upper surface of the transmission rollers, which facilitates the conveying of the sealed component by changing direction by 90 degrees.

[0014] As a further optimization of the above technical solution, the conveying mechanism is composed of fifth conveyor belts arranged at intervals. At the bagging position, there are two or more lifting pallets on the worktable between adjacent fifth conveyor belts, which are driven to rise and fall by the first cylinder. After the lifting pallets lift the assembly conveyed by the assembly feeding mechanism, it is convenient for the conveying rod of the assembly feeding mechanism to be retracted. After the lifting pallets fall, the assembly containing the plastic bag can be conveyed to the sealing position by the power-driven conveying mechanism.

[0015] The advantages of this invention compared to the prior art are:

[0016] 1. The present invention uses a controller to control each mechanism to operate according to a set program. During the operation, while loading the assembly parts into plastic bags, the plastic bags containing the assembly parts are vacuum sealed by a vacuum machine, so as to achieve continuous production, without too much waiting time and with high production efficiency.

[0017] 2. This invention achieves fully automated bagging and packaging of assembled parts throughout the entire process, avoiding human error in packaging and reducing production costs.

[0018] 3. This invention achieves standardized packaging, ensuring uniform packaging quality for products.

[0019] 4. In this invention, vacuum suction cups on the upper and lower sides are used to automatically open the plastic bag opening when the assembly is bagged and sealed. This facilitates the flattening of the plastic bag opening during bagging and sealing, ensuring that the upper and lower layers of the electrically heated plastic bag opening are flat and aligned. This prevents wrinkles or folds in the upper and / or lower layers that could lead to uneven heating and poor sealing results.

[0020] 5. The present invention vacuums the plastic bag before sealing. The vacuum-sealed plastic bag provides mutual positioning and protection for the packaged assemblies, which is beneficial for packing, storage and transportation.

[0021] 6. In this invention, the assembly on the assembly feeding mechanism is lifted by a cantilevered support plate of the bagging mechanism and fed into a plastic bag. Since the width of the cantilevered support plate is smaller than the width of the feeding mechanism and the assembly, the plastic bag will not be scratched or punctured when it is filled into the bag, which creates conditions for the next step of vacuuming. After the lifting support plate is raised, it lifts the plastic bag containing the assembly, which makes it easy for the cantilevered support plate to be pulled back smoothly. The plastic bag will not be scratched when the cantilevered support plate is pulled back.

[0022] 7. The present invention centrally sets up a vacuum feeding mechanism, a plastic bag stacking position, a first opening support mechanism, and an assembly feeding mechanism at the bag-packing position, and centrally performs the opening support, vacuuming, flattening, and sealing actions of the plastic bag opening at the sealing position, thereby reducing the equipment's operating time and space occupation, making the equipment structure compact, occupying a small workshop area, and facilitating equipment monitoring and management.

[0023] 8. The equipment of the present invention has a compact structure, occupies little workshop space, and is fully automated in packaging large semi-finished or finished products with plastic bags. It has high production efficiency, good packaging quality, and is suitable for packaging large industrial products. Attached Figure Description

Under the program control of the controller: the vacuum feeding mechanism 4 conveys the plastic bags 94 from the plastic bag stacking position to the conveying mechanism; the first opening mechanism opens the bag openings of the plastic bags conveyed to the conveying mechanism; and the assembly feeding... Mechanism 1 transports assembly 93 into plastic bag 94. Conveying mechanism 3 transports assembly 93 containing plastic bag 94 to second opening mechanism 5. Second opening mechanism 5 opens the opening of plastic bag 94. Flattening mechanism 8 flattens the opening of plastic bag 94 containing assembly.

By controlling the first and second upper vacuum suction cups on the upper side to move upward, the opening of plastic bag can be opened.

[0037] As a further optimization of the above technical solution, the vacuum feeding mechanism 4 includes a first slide rail 42 horizontally arranged on a first support 40, on which a first slider 43 is slidably mounted and driven to slide along the first slide rail 42.

The first mounting frame 44 has multiple rows and columns of third vacuum suction cups 45 arrayed on it for adsorbing plastic bags 94. The third vacuum suction cups 45 are connected in sequence to a solenoid valve, a vacuum tank and a vacuum pump through a conduit. The opening and closing of the solenoid valve is controlled by a controller to control whether the third vacuum suction cups 45 adsorb or not adsorb the upper surface of the plastic bag 94.

[0038] As a further optimization of the above technical solution, an assembly guide mechanism 14 is provided at the outlet of the assembly feeding mechanism 1. The assembly guide mechanism 14 has two vertically arranged moving plates 142 that slide on the first transverse slide 143 that spans the upper crossbeam of the assembly feeding mechanism. These moving plates 142 are driven by the first motor 141 and the first conveyor belt 144 to move closer or further apart along the first transverse slide 143. A lower guide block 147 is provided at the lower part of the moving plate 142. An upper guide block 148 that slides on the upper vertical slide is driven by the second motor 149 to move up and down. A first outward bending part 145 is provided at the rear of the lower guide block 147. A second upward bending part 146 is provided at the rear of the upper guide block 148.

[0039] As a further optimization of the above technical solution, the first support mechanism 2 is driven by a second cylinder 20 vertically mounted on the upper crossbeam of the assembly feeding mechanism 1 to move the second mounting frame 22 up and down. The lower part of the second mounting frame 22 is provided with two or more first upper vacuum suction cups 21 with downward-facing suction ports. On the first worktable 100 below the first upper vacuum suction cups 21, two or more first lower vacuum suction cups 23 with upward-facing suction ports are provided. The first lower vacuum suction cups 23 are staggered from the first upper vacuum suction cups 21. The second support mechanism 5 is a second bracket 63 located on one side of the sealing position 32. The sealing cylinder 52 drives the third mounting bracket 53 to move up and down. The lower part of the third mounting bracket 53 is provided with two or more second upper vacuum suction cups 51 with suction ports facing downwards. On the first worktable below the second upper vacuum suction cups 51, there are two or more second lower vacuum suction cups 50 with suction ports facing upwards. The second lower vacuum suction cups 50 are staggered from the second upper vacuum suction cups 51. The first and second upper vacuum suction cups and the first and second lower vacuum suction cups of the first opening mechanism 2 and the second opening mechanism 5 are respectively connected to the solenoid valve, the vacuum tank and the vacuum pump in sequence through the conduit. The solenoid valve is controlled by the controller.

[0040] As a further optimization of the above technical solution, the assembly feeding mechanism 1 includes a second conveyor belt 10 with power drive on both sides of the frame.

The bagging mechanism 13 includes a second slider 135 slidably mounted on a longitudinal third slide rail 132, driven by a power source such as a fourth electric motor 133 to slide along the third slide rail 132. A fourth slide rail 138 is vertically mounted on the second slider 135. The upper slide is equipped with a third cylinder 134 to drive the cantilever plate 131 to slide along the fourth slide rail 138. The bottom of the cantilever plate 131 is attached to the roller 137 of the third bracket 136 at the end of the third slide rail 132. The action of the third cylinder 134 causes the cantilever plate 131 to rise so as to disengage the assembly 93 on the second conveyor belt 10. The action of the power-driven second slider 135 can send the assembly 93 on the cantilever plate 131 into the plastic bag 94. After that, the controller controls the cantilever plate 131 to retract and then descend to reset.

[0041] As a further optimization of the above technical solution, the flattening mechanism 8 has a third slider 87 that is driven to slide along the longitudinal slide 88 on the first worktable 100.

The two support plates 83 are driven by a third conveyor belt 89 driven by a power source such as a first electric motor 891, and move closer to or further away from each other along the second transverse slide 81. When the two support plates 83 move longitudinally and insert into the opening of the plastic bag 94, and then move laterally away from each other, the opening of the plastic bag 94 will be flattened.

[0042] As a further optimization of the above technical solution, the middle of the second transverse slide is provided with two or more vacuum suction flat tubes 85 that extend toward the conveying mechanism 3 and are connected to the solenoid valve, vacuum tank and vacuum pump in sequence through conduits.

The first upper sealing plate 62, which is electrically heated, is driven downward by the fifth cylinder 60 to cooperate with the first lower sealing plate 66 to press the opening of the plastic bag 94 and hold it for a set time to achieve heat sealing of the opening of the plastic bag 94. The sealing mechanism 6 is provided with two sets at longitudinal intervals. The upper sealing plate 62, the first lower sealing plate 66, and the fifth cylinder 60 constitute a front sealing mechanism 6.

[0044] As a further optimization of the above technical solution, the end of the conveying mechanism 3 is provided with a longitudinal conveying mechanism 7 for conveying the sealed plastic bag. The sealing component conveying mechanism 7 includes a lifting plate 74 on the second workbench 101, which is driven and raised by a seventh cylinder 71 at intervals.

Two or more longitudinal fourth conveyor belts 76 driven by a power source such as a third electric motor 73 are provided between adjacent lifting plates 74 and on the outside of the lifting plate 74. After the lifting plate 74 is lowered, the upper surface of the fourth conveyor belt 76 is higher than the upper surface of the transmission rollers 75.

[0045] As a further optimization of the above technical solution, the conveying mechanism 3 is composed of five conveyor belts arranged at intervals. At the bagging position 31, there are two or more lifting pallets 90 that are driven to rise and fall by the first cylinder 92, respectively. After the lifting pallet 90 lifts the assembly 93 conveyed by the assembly feeding mechanism 1, it is convenient for the conveying rod of the assembly feeding mechanism 1 to be retracted. After the lifting pallet 90 falls, the assembly with plastic bag 94 can be conveyed to the flattening mechanism 8 by the power-driven conveying mechanism 3. The conveying mechanism 3 is composed of multiple fifth conveyor belts arranged at intervals and driven by power.

[0046] As a further optimization of the above technical solution, the power source is an electric motor or a cylinder.

[0047] The working process of this invention is as follows: Under the program control of the controller, the assembled parts are packaged in plastic bags, vacuum-sealed, and then sent out in the following order:

[0048] (1) The vacuum feeding mechanism 4 lifts the plastic bag 94 on the plastic bag stacking position by the third vacuum suction cup 45 and then transports it to the bag-covering position 31 of the conveying mechanism and puts it down.

[0049] (2) The first lower vacuum suction cup 23 and the first upper vacuum suction cup 21 of the first opening mechanism 2 respectively adsorb the upper and lower layers of the plastic bag opening. The first upper vacuum suction cup 21 can open the plastic bag opening by raising it. The second conveyor belt 10 of the assembly feeding mechanism 1 transports the assembly 93 to the outlet of the assembly feeding mechanism 1. Under the guidance of the assembly guiding mechanism 14, the front part of the cantilever plate 131 of the bagging mechanism 13 supports the assembly 93 and rises and extends into the plastic bag 94. The lifting plate 90 rises and lifts the assembly 93 of the plastic bag away from the cantilever plate 131. The cantilever plate 131 is pulled back to its original position. The lifting plate 90 descends and places the assembly 93 of the plastic bag on the fifth conveyor belt of the conveying mechanism. The fifth conveyor belt of the conveying mechanism moves the assembly 93 of the plastic bag to the sealing position 32.

[0050] (3) The second lower vacuum suction cup 50 of the second opening mechanism 5 adsorbs the lower surface of the opening of the plastic bag 94. The second upper vacuum suction cup 51, driven by the sealing cylinder 52, first moves down to adsorb the upper surface of the opening of the plastic bag 94, and then moves up to open the opening of the plastic bag. The two support plates 83 of the flattening mechanism 8 first extend into the opening of the plastic bag 94, and then move to both sides to flatten the plastic bag 94 and then exit the opening of the plastic bag 94. The vacuum suction flat tube 85 extends into the opening of the plastic bag 94 and connects to the vacuum tank to open the plastic bag 94. After the internal vacuum is drawn, the first upper sealing plate 62 and the second upper sealing plate 61 of the electrically heated sealing mechanism 6 move downwards and cooperate with the first lower sealing plate 66 and the second lower sealing plate 65 to press the opening of the plastic bag 94 and hold it for a set time to achieve heat sealing of the opening of the plastic bag 94 to form the packaged finished product. The first lower sealing plate 66 and the second lower sealing plate 65 then retract. As needed, one set of sealing mechanisms or two sets of sealing mechanisms can be used to seal the opening of the plastic bag 94. The two support plates 83 of the flattening mechanism 8 reset and retract.

[0051] (4) When the conveying mechanism 3 is working, the sealed finished product continues to be transported to the end of the conveying mechanism. The fifth conveyor belt of the conveying mechanism continues to operate, driving the packaged finished product to the transmission roller 75 of the packaging component conveying mechanism 7. Driven by the power, the transmission roller 75 completely transfers the packaged finished product to the second workbench 101. The lifting plate 74 drives the transmission roller 75 to move down, so that it lands on the fourth conveyor belt 76 driven by the power, such as the third motor 73. The fourth conveyor belt 76 works to turn the packaged finished product 90 degrees and send it out, so as to save the length space of the factory.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that simple substitutions or modifications can still be made to the technical solutions or technical features described in the foregoing embodiments, and these simple substitutions or modifications do not cause the essence of the corresponding technical solutions to deviate from the spirit and substance of the technical solutions of the embodiments of the present invention, and are still within the protection scope of the present invention.

On the first worktable below the second upper vacuum suction cups, two or more second lower vacuum suction cups with upward-facing suction ports are mounted. The second lower vacuum suction cups are staggered from the second upper vacuum suction cups. Both the second upper and second lower vacuum suction cups are connected sequentially to a solenoid valve, a vacuum tank, and a vacuum pump via conduits. The solenoid valve's operation is controlled by the controller.

4. The industrial continuous bagging packaging equipment according to claim 1, characterized in that: The flattening mechanism consists of a third slider that slides along a longitudinal slide on a first worktable, driven by a power source. Two support plates that extend toward the conveying mechanism slide along a second transverse slide on the third slider. The two support plates are driven by a third conveyor belt to move closer to or further away from each other along the second transverse slide. When the two support plates move longitudinally into the opening of the plastic bag and then move laterally away from each other, the opening of the plastic bag will be flattened.

5. The industrial continuous bagging packaging equipment according to claim 4, characterized in that: The second transverse slide is provided with two or more vacuum suction flat tubes that extend toward the conveying mechanism and are connected to the solenoid valve, vacuum tank and vacuum pump in sequence through conduits. The front end of the vacuum suction flat tube is provided with a suction port and the solenoid valve is controlled by the controller.

6. The industrial continuous bagging packaging equipment according to claim 1, characterized in that: The end of the conveying mechanism is provided with a longitudinal conveying mechanism for the sealed plastic bag. The sealing component conveying mechanism includes a lifting plate that is spaced apart on the second workbench and driven to rise and fall by a sixth cylinder. Multiple synchronously rotating transmission rollers driven by power are provided on the lifting plate. Two or more longitudinally driven fourth conveyor belts are provided between adjacent lifting plates and on the outside of the lifting plate. After the lifting plate descends, the upper surface of the fourth conveyor belt is higher than the upper surface of the transmission rollers.

7. The industrial continuous bagging packaging equipment according to claim 1, characterized in that: The conveying mechanism consists of five conveyor belts arranged at intervals. At the bagging position, there are two or more lifting pallets on the worktable between adjacent fifth conveyor belts, each driven to rise and fall by a first cylinder. After the lifting pallets lift the assemblies conveyed by the assembly feeding mechanism, it is convenient for the conveying rod of the assembly feeding mechanism to be retracted. After the lifting pallets fall, the power-driven conveying mechanism transports the assemblies covered with plastic bags to the sealing position.
