Technical Field

[0001] This invention belongs to the field of packaging technology, specifically relating to a vacuum machine and its operating method. Background Technology

[0002] In the past, the processes of opening bags, feeding materials, vacuuming, and sealing bags in packaging machines required manual labor or the assistance of multiple other devices. This was not only inefficient and ineffective, but also could not guarantee that the number of workpieces in each box and bag was the same, thus failing to guarantee packaging quality and efficiency. Summary of the Invention

[0006] Specifically, the heat-sealing assembly includes a clamping assembly mounted on a lateral moving device three, while at least one mounting plate is movably placed on a track via a lateral moving device two, and the heat-sealing component is mounted on the mounting plate.

[0007] Specifically, the clamping assembly includes a base frame, a clamping plate 1 and a clamping plate 2 movably mounted on the base frame, the clamping plate 1 and the clamping plate 2 being connected by a cylinder 1, and both ends of the clamping plate 1 and the clamping plate 2 being equipped with an adsorption head 1.

[0008] Specifically, the heat-sealing component includes a support frame placed on a track, with the track passing between clamp plate one and clamp plate two. The support frame is mounted on the transverse moving device two via a mounting plate. Heat-sealing plate one is movably mounted on both ends of the mounting plate. Heat-sealing plate two is hinged to heat-sealing plate one and spring-connected to heat-sealing plate one. One end of heat-sealing plate two is movably mounted on the mounting plate via a miniature cylinder.

[0009] Specifically, the mounting plate is equipped with a groove rail. When the heat sealing plate moves along the rail between clamp plate one and clamp plate two, clamp plate one is placed in the groove rail.

[0010] Specifically, both heat-sealing plate one and heat-sealing plate two are lower than adsorption head one.

[0011] Specifically, the distance between the two adsorption heads is equal to the distance between the two heat-sealing plates, which is equal to the width of the packaging bag.

[0012] Specifically, the statistical components include a frame, a movable plate mounted on the frame via cylinder three, a pressure plate two mounted on the movable plate, a pressure plate one mounted on the inner wall of the frame, a guide plate mounted on the top of the frame via cylinder five, and a counting sensor mounted on the inner wall of the frame or on the movable plate.

[0013] Specifically, the adsorption transfer assembly includes a mounting frame, a motor mounted on the mounting frame, a rotating column mounted on the motor, a rotating block mounted on the rotating column, both ends of the rotating block being elastically mounted on the second adsorption head, a fourth cylinder located above the second adsorption head and mounted on the mounting frame, a limiting frame movably mounted on the worktable via a fourth transverse moving device, a through hole provided on the limiting frame, and a sensor mounted on the limiting frame, and in the initial state, the closest vertical distance between the third adsorption head and the limiting frame is equal to the thickness of a workpiece.

[0014] Based on the above-described apparatus, the present invention also proposes an operating method for using the aforementioned vacuum machine, comprising the following steps:

[0015] S1, the bag feeding assembly conveys the packaging bag to the heat sealing assembly;

[0016] S2, the heat sealing component opens the packaging bag, and the horizontal moving device drives the adsorption transfer component to the top of the packaging bag;

[0017] S3, The workpiece is placed into the packaging bag by the adsorption and transfer component;

[0018] S4, After the workpieces in a bag are placed, the lateral moving device drives the vacuum suction head to move above the packaging bag;

[0019] S5, the telescopic cylinder pushes the vacuum nozzle into the packaging bag, and the vacuum nozzle performs vacuuming;

[0020] S6, The heat sealing component performs heat sealing operation on the packaging bag;

[0021] S7, the heat-sealing component places the sealed packaging bag into the counting component;

[0022] S8, the counting component counts the number of finished products, and at the same time the finished products fall onto the conveyor belt, which then sends the finished products into the collection box;

[0023] S9. Repeat all the above steps until the collection box is full of finished products, then replace it with a new collection box.

[0024] The beneficial effects of this invention are:

[0025] 1. This device automates all operations, including opening packaging bags, placing workpieces, vacuuming, heat sealing, counting, and boxing. It also ensures that each bag and box contains the same number of workpieces, guaranteeing packaging efficiency and quality, and preventing any omissions.

[0026] 2. The design of the adsorption transfer component in this device can prevent the stacking of thin sheet-like workpieces and scrape off excess adsorbed workpieces when picking up workpieces, thereby further ensuring that the number of workpieces in each bag is the same and preventing workpieces from being not properly adsorbed, which would affect subsequent operations.

[0040] like Figure 1 As shown, the present invention provides a vacuum machine, including a worktable 1, an adsorption transfer assembly 4 movably mounted on the worktable 1 via a transverse moving device 2, a vacuum suction head 3 movably mounted on the transverse moving device 2 via a telescopic cylinder, a heat sealing assembly 5 and at least one statistical assembly 7 mounted on the worktable 1, each of the statistical assemblies 7 being equipped with a bag feeding assembly 6, a conveyor belt 8 located below the statistical assembly 7, and a collection box 9 located on one side of the conveyor belt 8.

[0041] The bag feeding assembly 6 places the packaging bag into the heat sealing assembly 5, and then the adsorption transfer assembly 4 puts the workpiece into the packaging bag. Subsequently, the heat sealing assembly 5 vacuums and heat seals the packaging bag, which is then sent to the counting assembly 7 to count the number of finished products. Finally, the conveyor belt 8 sends the finished products into the collection box 9. The adsorption transfer assembly 4 counts the number of workpieces put in, and the counting assembly 7 counts the number of finished products. When the collection box 9 receives a uniform number of finished products, a signal is transmitted to notify the staff to replace the collection box 9 and pack and seal the full collection box 9, thereby ensuring that the number of products in each bag and box is the same, thus ensuring the packaging quality.

[0042] Please refer to this carefully. Figure 2 The heat sealing assembly 5 includes a clamping assembly 506 mounted on a transverse moving device 3 505, while at least one mounting plate 502 is movably placed on a track 503 via a transverse moving device 2 501, and a heat sealing component 504 is mounted on the mounting plate 502.

[0043] The lateral moving device 3 505 drives the clamping component 506 to move to the bag feeding component 6. The bag feeding component 6 feeds the packaging bag into the clamping component 506, and the clamping component 506 clamps the packaging bag. Then, the lateral moving device 3 505 drives the clamping component 506 to move to the adsorption transfer component 4. The adsorption transfer component 4 puts the workpiece into the packaging bag. Then, the vacuum suction head 3 draws a vacuum. Finally, the lateral moving device 2 501 drives the heat sealing component 504 to move along the track 503. The heat sealing component 504 heat seals the opening of the packaging bag filled with the workpiece.

[0044] The clamping assembly 506 includes a base frame 5065, a clamping plate 5061 and a clamping plate 5063 movably mounted on the base frame 5065, the clamping plate 5061 and the clamping plate 5063 are connected by a cylinder 5064, and both ends of the clamping plate 5061 and the clamping plate 5063 are equipped with an adsorption head 5062.

[0045] The heat sealing component 504 includes a support frame 5044 placed on a track 503, with the track 503 passing between a first clamping plate 5061 and a second clamping plate 5063. The support frame 5044 is mounted on a second transverse moving device 501 via a mounting plate 502. A first heat sealing plate 5041 is movably mounted on both ends of the mounting plate 502. A second heat sealing plate 5042 is hinged to the first heat sealing plate 5041 and is connected to the first heat sealing plate 5041 via a first spring 5043. One end of the second heat sealing plate 5042 is movably mounted on the mounting plate 502 via a miniature cylinder.

[0046] The distance between the two adsorption heads 5062 is equal to the distance between the two heat sealing plates 5041, which is equal to the width of the packaging bag. At the same time, both heat sealing plates 5041 and 5042 are lower than the adsorption head 5062. The mounting plate 502 is provided with a groove. When the heat sealing plate moves along the track 503 between clamping plates 5061 and 5063, clamping plate 5061 is placed in the groove. Therefore, the heat sealing plate can reach both ends of the packaging bag without interference.

[0047] Initially, the two heat-sealing components 504 are located at opposite ends of the two lateral moving devices 501. When a bag needs to be placed, the clamping assembly 506 moves to the front of the bag feeding assembly 6 on one side via the lateral moving device 505, activating the cylinder 5064. The cylinder 5064 pushes open the clamping plate 5063, and the bag feeding assembly 6 places the packaging bag on the clamping plate 5063. The suction head 5062 picks up the packaging bag, and then the cylinder 5064 lifts the clamping plate 5063, allowing the suction head 5062 on the clamping plate 5061 to pick up the other side of the packaging bag, thus opening the packaging bag. This facilitates the subsequent transfer of the workpiece into the packaging bag by the suction transfer assembly 4. Afterwards, a vacuum... The suction head 3 is inserted into the packaging bag to draw a vacuum. Then, the lateral moving device 2 501 drives the heat sealing component 504 on one side to move along the track 503 and activates the micro cylinder. At this time, the heat sealing plate 1 5041 and the heat sealing plate 2 5042 are located on both sides of the packaging bag. Subsequently, the micro cylinder drives the heat sealing plate to clamp the packaging bag and simultaneously activates the heat sealing plate. At this time, the heat sealing plate is located below the vacuum suction head 3. Therefore, the lateral moving device 2 501 can drive the heat sealing plate to heat seal the entire opening of the packaging bag. Then, the lateral moving device 3 505 drives the clamping component 506 to move to the counting component 7. The cylinder 1 5064 pushes the clamping plate 2 5063 down. Under the action of gravity, the finished product falls from the counting component 7.

[0048] Please refer to this carefully. Figure 3 The bag assembly 6 includes an inclined storage rack 601, in which the packaging bag is placed, and an adsorption head 603 is movably mounted on the storage rack 601 via a cylinder 602.

[0049] Adsorption head 603 sucks the packaging bag out of storage rack 601 and places it between clamping plate 5061 and clamping plate 5063.

[0050] Please refer to this carefully. Figure 4 The statistical component 7 includes a frame 701, a movable plate 704 is movably mounted on the frame 701 via a cylinder 702, a pressure plate 706 is mounted on the movable plate 704, a pressure plate 705 is mounted on the inner wall of the frame 701, a guide plate 703 is movably mounted on the top of the frame 701 via a cylinder 707, and a counting sensor is mounted on the inner wall of the frame 701 or on the movable plate 704.

[0051] Both pressure plate 2 706 and pressure plate 1 705 are elastic. At the same time, during operation, cylinder 3 702 drives pressure plate 2 706 to move, so that it does not obstruct the finished product from falling, and ensures that when the finished product falls, it drives pressure plate 2 706 and pressure plate 1 705 to move and touch the counting sensor, so that the counting sensor transmits a signal to count.

[0052] The counting sensor can be a contact sensor, a photoelectric counting sensor, or a proximity switch, etc.

[0053] After sealing, cylinder 5 707 is activated, which moves guide plate 703 to below the finished product. When cylinder 1 5064 pushes clamping plate 2 5063 down, the finished product falls between pressure plate 2 706 and pressure plate 1 705 along guide plate 703 under the action of gravity.

[0054] Please refer to this carefully. Figure 5 The adsorption transfer assembly 4 includes a mounting frame 401, a motor 402 mounted on the mounting frame 401, a rotating column 403 mounted on the motor 402, a rotating block 406 mounted on the rotating column 403, both ends of the rotating block 406 being elastically mounted on the adsorption head 404 via springs 405, a cylinder 407 located above the adsorption head 404 and mounted on the mounting frame 401, and a limiting frame 408 movably mounted on the worktable 1 via a transverse moving device 4. The limiting frame 408 has a through hole 410, and a sensor 408 is mounted on the limiting frame 408. In the initial state, the closest vertical distance between the adsorption head 404 and the limiting frame 408 is equal to the thickness of a workpiece.

[0055] The workpiece is a thin sheet product, such as a gasket. Therefore, the design of the adsorption transfer component 4 can prevent the thin sheet workpieces from stacking, and the limit frame 408 scrapes off the excess adsorbed workpiece.

[0056] The limiting frame 408 is installed on the transverse moving device 4 via a shelf. The workpiece stacks are located on both sides of the limiting frame 408 and are placed on the shelf, so the workpiece stacks move with the limiting frame 408.

[0057] When the workpiece is placed, the lateral moving device 2 moves the rotating block 406, and at the same time, the lateral moving device 4 moves the limiting frame 408, so that the through hole 410 is above the packaging bag. Then, the cylinder 407 is turned on, and the cylinder 407 pushes the adsorption head 404 to adsorb the workpiece. Then, the motor 402 is turned on, and the motor 402 drives the rotating block 406 to rotate. The limiting frame 408 scrapes away the excess workpiece, and then the adsorption head 404 stops directly above the through hole 410. Finally, the adsorption head 404 releases the workpiece, and the workpiece falls into the packaging bag through the through hole 410. At the same time, the sensor 409 starts counting.

[0058] Sensor 409 is a proximity switch or photoelectric sensor, etc. Meanwhile, lateral movement device 1 2, lateral movement device 2 501, lateral movement device 3 505 and lateral movement device 4 are single-axis robots, electric cylinders or electric lead screws, etc.

[0059] Vacuum suction head 3, telescopic cylinder, lateral movement device 1 2, lateral movement device 2 501, lateral movement device 3 505, lateral movement device 4, conveyor belt 8, heat sealing plate 1 5041, heat sealing plate 2 5042, suction head 1 5062, cylinder 1 5064, cylinder 2 602, suction head 2 603, cylinder 5 707, cylinder 3 702, motor 402, cylinder 4 407, suction head 3 404, sensor and counting sensor communication coupled control panel.

[0060] The control panel contains a PLC controller, which is a programmable numerical control system. The PLC acts as the central control system, using a touchscreen to input programs and control the entire machine, achieving full automation of the transportation process. The control system connects various actuators, allowing them to move along logical trajectories. Programming controls enable these actuators to operate according to the required steps.

[0061] Based on the above-described apparatus, the present invention also proposes an operating method for using the aforementioned vacuum machine, comprising the following steps:

[0062] Step 1: The bag feeding assembly 6 conveys the packaging bag to the heat sealing assembly 5;

[0063] Step 2: The heat sealing component 5 opens the packaging bag, and the horizontal moving device 2 drives the adsorption transfer component 4 to the top of the packaging bag;

[0064] Step 3: The adsorption transfer component 4 places the workpiece into the packaging bag;

[0065] Step 4: After the workpieces in one bag are placed, the lateral moving device 2 drives the vacuum suction head 3 to move above the packaging bag;

[0066] Step 5: The telescopic cylinder pushes the vacuum nozzle 3 into the packaging bag, and the vacuum nozzle 3 performs vacuuming.

[0067] Step 6: The heat sealing component 5 heat seals the packaging bag.

[0068] Step 7: The heat-sealing component 5 places the sealed packaging bag into the counting component 7;

[0069] Step 8: The counting component 7 counts the number of finished products, and at the same time the finished products fall onto the conveyor belt 8, which then sends the finished products into the collection box 9.

[0070] Step 9: Repeat all the above steps until collection box 9 is full of finished products, then replace it with a new collection box 9.

[0071] This device automates all operations, including opening packaging bags, placing workpieces, vacuuming, heat sealing, counting, and boxing. It ensures that each bag and box contains the same number of workpieces, guaranteeing packaging efficiency and quality and preventing any omissions. Furthermore, the design of the adsorption transfer component 4 prevents the stacking of thin, sheet-like workpieces during adsorption, scraping off excess workpieces to further ensure the same number of workpieces per bag and prevent incomplete adsorption that could affect subsequent operations.
