Description

Technical Field

[0001] This utility model relates to the field of automated tooling production equipment technology, and in particular to an automated filling and packaging equipment. Background Technology

[0002] In recent years, more and more high-end daily chemical products, household goods, and food products have adopted colorful bottles, which greatly enhances the packaging quality of the products and makes them more popular.

[0003] In the bottled product filling and sealing production line, a series of operations are required, including empty bottle loading, cleaning, filling, weighing, and capping. During the production process, the weight of the bottles can vary, making it difficult to verify the quality of the filling material and the weight of the filled product after filling. Using the final bottle weight as the measurement standard can lead to inaccurate measurements due to the inherent bottle weight variation. Therefore, weighing the bottles before and after filling, and then subtracting the empty bottle weight from the total weight, yields the final weight of the filled product. Using this final weight for inspection ensures a higher pass rate.

[0004] During the filling process, bottles are transported along a mold conveyor line, passing sequentially through filling stations for filling. However, it is difficult to weigh the bottles during this process. Patent application CN119774525A discloses a multi-head weighing and filling machine, which requires moving the bottles from the original conveyor line to the weighing and filling stations during weighing and filling. This process is structurally complex, and the bottles may break or become soiled during the relocation process.

[0005] Therefore, there is an urgent need to design a production equipment that can simultaneously perform weighing and filling operations without needing to move the equipment. Utility Model Content

[0006] Purpose of the utility model: To address the problems existing in the prior art, this utility model provides an automated filling and packaging equipment. A notch is directly opened in the mold conveying mechanism, and the weighing mechanism is directly set on the mold conveying mechanism. The bottle does not need to be moved out to achieve weighing before and after filling, and the weighing does not affect the continued transmission of the bottle.

[0007] Technical Solution: This utility model provides an automated filling and packaging equipment, including a workbench with a mold conveying mechanism and a pair of clamping members spaced apart on the workbench. A filling mechanism is also connected to the workbench, with its filling head facing the mold conveying mechanism. Identical first and second weighing mechanisms are also provided on the workbench on both sides of the filling mechanism. Each weighing mechanism includes a weighing block located directly below the mold conveying mechanism and a lifting assembly. The weighing block is connected to a weighing sensor, which is mounted on the lifting assembly. A notch slightly larger than the weighing block is provided at a position corresponding to the position of the mold conveying mechanism and the weighing block. The lifting assembly drives the weighing block to extend beyond the notch.

[0008] Furthermore, the mold conveying mechanism includes a first conveyor belt, a second conveyor belt, and a conveying pallet disposed between the first and second conveyor belts. The conveying pallet has a notch, slightly larger than the weighing block, at a position corresponding to the symmetrical load block. The first conveyor belt is provided with a left clamping member at intervals, and the second conveyor belt is provided with a right clamping member. The clamping heads of the left and right clamping members are positioned directly opposite each other above the conveying pallet.

[0009] Furthermore, the first and second conveyor belt conveyors have the same structure, both including a main drive pulley, a driven pulley, and a conveyor belt located between the main drive pulley and the driven pulley, wherein the main drive pulley is driven and connected to a drive motor.

[0010] Furthermore, the extension assembly is an extension cylinder, and the actuator of the extension cylinder is connected to the weighing sensor.

[0011] Furthermore, the filling mechanism includes a trolley frame detachably connected to the workbench, a filling head base is provided on the trolley frame, and a filling head connected to the filling barrel is provided on the filling head base.

[0012] Furthermore, a blowing and suction mechanism is also provided on the workbench on one side of the mold conveying mechanism in front of the first weighing mechanism. The blowing and suction mechanism includes a blowing and suction pipe and a lifting component that drives the blowing and suction pipe up and down. The blowing and suction pipe is connected to a blower that can be used for both blowing and suction. The end of the blowing and suction pipe is also connected to a bottle mouth corresponding block, which is directly opposite the mold conveying mechanism.

[0013] Furthermore, the blowing and suction mechanism also includes a blowing and suction buffer tube, through which a main blowing and suction rod passes. The blowing and suction tube passes through the main blowing and suction rod, and a spring pressure block is fixed on the main blowing and suction rod. A buffer spring is sleeved on the main blowing and suction rod between the blowing and suction buffer tube and the spring pressure block.

[0014] Furthermore, the lifting assembly includes a lifting cylinder, the actuating end of which is connected to a blow-suction mounting plate, and the blow-suction main rod is fixedly connected to the blow-suction mounting plate.

[0015] Furthermore, the lifting assembly is also disposed on the height fine-tuning assembly, the height fine-tuning assembly includes an adjusting handwheel and an adjusting screw, the adjusting handwheel is fixedly connected to one end of the adjusting screw, the adjusting screw is threadedly connected to the adjusting block, and the lifting assembly is fixed on the adjusting block.

[0016] Furthermore, a feeding mechanism is also provided on the workbench on one side of the mold conveying mechanism after the second weighing mechanism. The feeding mechanism includes a feeding conveyor belt, a feeding robot, and a driving component, which are located on one side of the mold conveying mechanism. The driving component drives the feeding robot to grab the bottle and move it onto the feeding conveyor belt.

[0017] Furthermore, the driving component includes a longitudinal driving cylinder and a transverse driving cylinder. The longitudinal driving cylinder is connected to a transverse slide rail set on a fixed base plate via a transverse sliding plate. The actuating end of the longitudinal driving cylinder is connected to the unloading robot, and the actuating end of the transverse driving cylinder is connected to the transverse sliding plate.

[0018] Furthermore, a lifting adjustment screw is rotatably connected to the fixed base plate via a bearing. The lifting adjustment screw is threadedly connected to the adjustment base plate, which is fixed to the bracket. A rotating handle is also threadedly connected to the lifting adjustment screw above the adjustment base plate.

[0019] Beneficial effects:

[0020] 1. This utility model includes weighing mechanisms at both the front and rear of the filling mechanism. Before filling, the weight of each bottle is recorded. After filling, the bottles are weighed again. The weight of the filled product is then accurately obtained by subtracting the weight of the empty bottle before filling from the weight of the filled product. This allows for real-time monitoring to ensure the weight of the filled product meets requirements. To achieve weighing without transferring the production line, a notch slightly larger than the weighing block is provided at the corresponding position between the mold conveyor mechanism and the weighing block. During weighing, the weighing block is pushed out by the extension component, lifting the bottle and causing it to leave the mold conveyor mechanism. At this point, the weighing sensor can weigh the bottle. After weighing, the notch returns to its original position and continues to be conveyed forward on the mold conveyor mechanism.

[0021] 2. To enable the mold conveying mechanism to clamp, release, and extend the weighing block at the notch, this utility model places the left and right clamping components on two separate conveyor belts. When the bottle is clamped, the clamping head faces the conveyor tray positioned between the two conveyor belts. The bottle is held in place by the left and right clamping components. As the two conveyor belts transport the bottle forward, they move it forward. When the bottle is positioned at the weighing mechanism, it is directly opposite the notch on the conveyor tray. At this point, the two clamping components are slightly moved by the two conveyor belts to release the bottle. The weighing mechanism can then extend the bottle using the weighing block to complete the weighing process. The clamping and releasing of the bottle are controlled solely by the forward and reverse movement of the two conveyor belts. When the weighing block lifts the bottle, it does not contact the mold conveying mechanism and therefore does not affect the weight of the bottle itself.

[0022] 3. The top extension component of this utility model is set as a top extension cylinder, which is convenient for control.

[0023] 4. This utility model has a detachable filling mechanism installed on the workbench. As needed, the filling barrel and filling head can be moved from other places to the workbench via a trolley frame. After docking with the workbench, filling can be carried out. The filling barrel, filling head and trolley frame can be replaced as needed. If different products need to be filled, only the trolley frame of the different products needs to be replaced.

[0024] 5. This utility model blows and sucks the bottle body before weighing, which can remove dust and other debris in the bottle body. The lifting component is used to connect the corresponding block of the bottle mouth with the bottle body. The blower can blow and suck air at the same time.

[0025] 6. This utility model also provides a buffer structure on the blowing and suction tube. A buffer spring is sleeved between the blowing and suction buffer tube and the spring pressure block. During the downward movement of the lifting component, the corresponding block of the bottle mouth connects with the bottle body. At this time, pressing causes the blowing and suction main rod to slide up and down in the blowing and suction buffer tube. Due to the presence of the buffer spring, a buffering effect is achieved, preventing excessive force between the corresponding block of the bottle mouth and the bottle body, which could cause pressure damage to the bottle product.

[0026] 7. The height fine-tuning component designed in this utility model can fine-tune the height of the blowing and suction mechanism. When the height or size of the bottles to be weighed and filled is different, the height of the adjusting block can be fine-tuned by adjusting the adjusting screw through the handwheel. The adjusting block drives the lifting component (i.e., the lifting cylinder) on it to fine-tune the height to adapt to different bottle heights.

[0027] 8. This utility model includes a feeding mechanism after the second weighing mechanism. This feeding mechanism can be used to feed either defective bottles or qualified bottles, and can be adjusted according to the actual needs of the production line. If, after weighing, the bottles require further operations such as adding inner pads or capping, the mold conveyor continues to transport the bottles to the next station. At this time, the feeding mechanism feeds the defective bottles onto the feeding conveyor belt. When the production line is finished after filling and no further operations are required, the feeding mechanism can be used to feed all the bottles directly.

[0028] 9. This utility model uses a drive unit to drive the unloading robot to grip and move, achieved through a longitudinal drive cylinder and a transverse drive cylinder. The longitudinal drive cylinder drives the unloading robot downwards, while the gripping action is achieved through a gripper cylinder. The transverse drive cylinder drives the entire longitudinal drive cylinder to move back and forth, moving it closer to or away from the mold conveying mechanism. This control method only requires controlling the longitudinal and transverse drive cylinders, making it more convenient.

[0029] 10. This utility model can adjust the height of the unloading robot according to actual needs. By rotating the handle, the lifting adjustment screw moves up and down, which in turn moves the fixed base plate at its lower end up and down, thereby realizing the height adjustment of the entire drive component.

[0038] The present invention will now be described in detail with reference to the accompanying drawings.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0042] See Figure 1 This utility model discloses an automated filling and packaging equipment, including a workbench 1, on which a mold conveying mechanism 3 is provided, and pairs of clamping components are arranged at intervals on the mold conveying mechanism 3. A filling mechanism 2 is also connected to the workbench 1, with the filling head 201 of the filling mechanism 2 facing the mold conveying mechanism 3. First and second weighing mechanisms 4 and 5 with identical structures are also provided on the workbench 1 located on the front and rear sides of the filling mechanism 2. The first and second weighing mechanisms 4 and 5 include a weighing block 501 located directly below the mold conveying mechanism 3 and a top extension assembly. The weighing block 501 is connected to a weighing sensor 502, which is mounted on the top extension assembly. A notch 310, slightly larger than the weighing block 501, is provided at the position corresponding to the mold conveying mechanism 3 and the weighing block 501. The top extension assembly is used to drive the weighing block 501 to extend beyond the notch 501.

[0043] See Figures 2-4 The mold conveying mechanism 3 includes a first conveyor belt 303, a second conveyor belt 304, and a conveyor tray 309 disposed between the first conveyor belt 303 and the second conveyor belt 304. The conveyor tray 309 has a notch 310, slightly larger than the weighing block 501, at a corresponding position. The first conveyor belt 303 is provided with left clamping members 301 at intervals, and the second conveyor belt 304 is provided with right clamping members 302. The clamping heads of each pair of left clamping members 301 and right clamping members 302 are positioned facing each other above the conveyor tray 309.

[0044] In this embodiment, the first conveyor belt conveyor 303 and the second conveyor belt conveyor 304 have the same structure, both including a main drive pulley 305, a driven pulley 306, and a conveyor belt 307 located between the main drive pulley 305 and the driven pulley 306. The main drive pulley 305 is driven by a drive motor 308. The conveyor belts 307 of both are located on the same horizontal line and are driven synchronously by the drive motor 308.

[0045] When the mold conveying mechanism 3 clamps the bottle body 8, the distance between the left clamping member 301 and the right clamping member 302 is slightly larger than the diameter of the bottle body 8. During clamping, the first conveyor belt 303 moves a small distance from left to right, and the second conveyor belt 304 moves a small distance from right to left. The left clamping member 301 and the right clamping member 302 move closer together, clamping the bottle body 8. After clamping, the first conveyor belt 303 and the second conveyor belt 304 move forward synchronously. After reaching the position of the weighing mechanism 4, the bottle body is directly above the weighing support block 501. The first conveyor belt 303 and the second conveyor belt 304 stop moving. Then, the first conveyor belt 303 moves slightly in the reverse direction, and the second conveyor belt 304 continues to move slightly in the forward direction. At this time, the left clamping member 301 and the right clamping member 302 separate, and the bottle body 8 is released.

[0046] See Figure 4 The lifting assembly is a lifting cylinder 503, and the actuator of the lifting cylinder 503 is connected to the weighing sensor 502. During weighing, the lifting cylinder 503 extends the weighing sensor 502, which in turn drives the weighing support block 501 on it to lift the bottle body 8, thus completing the weighing operation. In this embodiment, the weighing sensor 502 can be a commercially available weighing sensor, and the specific model is not required.

[0047] See Figure 5 The filling mechanism 2 includes a trolley frame 202 detachably connected to the workbench 1. A filling head base 203 is mounted on the trolley frame 202, and a filling head 201 connected to a filling container 204 is mounted on the filling head base 203. During filling, the trolley frame 202 with the filling head 201 and filling container 204 can be transferred to the workbench 1 and fixed to it using bolts or other fixing methods. During filling, the connection between the filling container 204 and the filling head 201 can be controlled by a solenoid valve, etc., but this is not the focus of this invention and will not be further elaborated here.

[0048] See Figure 1 and Figure 6 Before weighing and filling, the bottle body 8 needs to be cleaned to prevent dust and other factors from affecting the weight of the bottle body 8. A blowing and suction mechanism 6 is also provided on the workbench 1 on one side of the mold conveying mechanism 3 in front of the first weighing mechanism 4. The blowing and suction mechanism 6 includes a blowing and suction pipe 601 and a lifting component that drives the blowing and suction pipe 601 up and down. The blowing and suction pipe 601 is connected to a blowing and suction dual-purpose blower (not shown in the figure). The end of the blowing and suction pipe 601 is also connected to a bottle mouth corresponding block 602, which is directly opposite the mold conveying mechanism 3.

[0049] The blowing and suction mechanism 6 also includes a blowing and suction buffer tube 604, through which a blowing and suction main rod 605 passes. A blowing and suction tube 601 passes through the blowing and suction main rod 605. A spring pressure block 606 is fixed on the blowing and suction main rod 605. A buffer spring 607 is sleeved on the blowing and suction main rod 605 between the blowing and suction buffer tube 604 and the spring pressure block 606.

[0050] See Figure 5 The lifting assembly includes a lifting cylinder 603, the actuating end of the lifting cylinder 603 is connected to a blow-suction mounting plate 608, and the blow-suction main rod 605 is fixedly connected to the blow-suction mounting plate 608.

[0051] During the blowing and suction process, the lifting cylinder 603 drives the blowing and suction mounting plate 608, which in turn moves the main blowing and suction rod 605 up and down. During this movement, when the bottle mouth corresponding block 602 contacts the bottle body 8 or the mold conveying mechanism 3, pressure exists between them. The main blowing and suction rod 605 continues to descend within the blowing and suction buffer tube 604, compressing the buffer spring 607. Thus, the bottle mouth corresponding block 602 and the bottle body 8 are buffered by the buffer spring 607. When the pressure reaches a certain level, the lifting cylinder 603 stops working. The blowing and suction operation is then started by a dual-purpose blower. After the blowing and suction is completed, the lifting cylinder 603 rises to return to its original position.

[0052] To accommodate bottles 8 of different heights, a lifting assembly is mounted on a height fine-tuning assembly. The height fine-tuning assembly includes an adjusting handwheel 609 and an adjusting screw 610. One end of the adjusting handwheel 609 is fixedly connected to the adjusting screw 610, and the adjusting screw 610 is threadedly connected to an adjusting block 611. The lifting assembly is fixed to the adjusting block 611. In this embodiment, the upper and lower ends of the adjusting screw 610 are rotatably connected to a fixed plate via bearings. The upper end passes through the fixed plate and is fixedly connected to the adjusting handwheel 609. A pair of guide rods are also provided on the fixed plate, and the adjusting block 611 passes through the guide rods to provide guidance.

[0053] See Figure 7 On the workbench 1 on one side of the mold conveying mechanism 3 after the second weighing mechanism 5, there is also a feeding mechanism 7. The feeding mechanism includes a feeding conveyor belt 701, a feeding robot 702 and a driving component, which are located on one side of the mold conveying mechanism 3. The driving component drives the feeding robot 702 to grab the bottle body 8 and move it onto the feeding conveyor belt 701.

[0054] In this embodiment, the driving component includes a longitudinal driving cylinder 703 and a transverse driving cylinder 704. The longitudinal driving cylinder 703 is connected to the transverse slide rail 707 set on the fixed base plate 706 via a transverse sliding plate 705. The actuating end of the longitudinal driving cylinder 703 is connected to the unloading robot 702, and the actuating end of the transverse driving cylinder 704 is connected to the transverse sliding plate 705.

[0055] A lifting adjustment screw 708 is rotatably connected to the fixed base plate 706 via a bearing. The lifting adjustment screw 708 is threadedly connected to the adjusting base plate 709. The adjusting base plate 709 is fixed on the bracket 710. The bracket 710 is vertically set on the worktable 1. A rotating handle 711 is also threadedly connected to the lifting adjustment screw 708 above the adjusting base plate 709.

[0056] Rotating the handle 711 raises or lowers the lifting adjustment screw 708, which in turn moves the fixed base plate 706 up and down, thus moving the longitudinal drive cylinder 703 and the transverse drive cylinder 704 up and down. The transverse drive cylinder 704 can be detachably mounted on a fixed frame. If the height needs to be adjusted by rotating the handle 711, the connection between the transverse drive cylinder 704 and the fixed frame should be loosened, and the transverse drive cylinder 704 should be fixed back after adjustment.

[0057] Working principle:

[0058] Bottle 8 is conveyed on mold transfer mechanism 3, first passing through blowing and suction mechanism 6, and then to first weighing mechanism 4. First conveyor belt 303 and second conveyor belt 304 drive left clamping member 301 and right clamping member 302 to release bottle 8. Extension cylinder 503 operates, extending weighing block 501 to obtain the weight of empty bottle 8. After weighing, it continues to move to filling mechanism 2. After filling, it continues to move to second weighing mechanism 4. The weighing process of second weighing mechanism 4 is the same as that of first weighing mechanism 4. After weighing, it reaches unloading mechanism 7, where longitudinal drive cylinder 703, transverse drive cylinder 704, and unloading robot 702 unload the bottle 8 onto unloading conveyor belt 701.

[0059] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
