[0016] By adopting the above technical solution, the utility model has the following beneficial effects:

[0018] (2) The utility model places the finished products that have been filled and capped at each independent weighing station and uses the weighing sensor at the bottom to weigh them.

DETAILED DESCRIPTION

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] (Example 1)

[0038] like Figures 1 to 6The fully automatic gravity filling, capping and checkweighing machine shown includes a frame 1, an empty bottle conveyor 2, a bottle cap conveyor 3, a finished product sorting section 4, and a star wheel conveyor 5, a filling section 6, a capping section 7, and a weighing section 8 mounted on the frame 1. The filling section 6, the capping section 7, and the weighing section 8 are sequentially connected via the star wheel conveyor, and the star wheel conveyor 5 connects the empty bottle conveyor 2, the bottle cap conveyor 3, and the finished product sorting section 4. Empty bottles to be filled are conveyed to the filling section 6 by the empty bottle conveyor 2 for filling, and then to the capping section 7. The capping section 7 tightens or presses the bottle caps conveyed from the bottle cap conveyor 3 onto the mouths of the filled bottles. The bottles are then conveyed to the weighing section 8 for checkweighing. Finally, the finished product sorting section 4 outputs qualified and unqualified products. The entire process is completed automatically.

[0039] Specifically, the empty bottle conveyor 2, bottle cap conveyor 3, star wheel conveyor 5, and capping unit 7 are all conventional structures in the field and will not be described in detail here. The filling unit 6 includes a filling table 6-1, a material box 6-2, a filling cam unit 6-3, a filling head 6-4, and a feed assembly 6-5. A geared disc is provided in the center of the filling table 1, which rotates around itself under external drive, thereby driving the empty bottles conveyed. The material box 6-2 is mounted above the filling table 6-1 and moves synchronously with the filling table 6-1. A top cover 6-2-1 is installed on top of the top cover 6-2-1, which rotates and seals with the material box 6-2, thereby remaining stationary as the material box 6-2 rotates. The filling cam unit 6-3 is mounted on the outside of the material box 6-2 and remains stationary as the material box 6-2 rotates. The feed assembly 6-5 is fixed to the top cover 6-2-1 and is connected to the material box 6-2. The filling head 6-4 is evenly installed on the material box 6-2 along the circumference, and moves synchronously with the material box 6-2. The top part cooperates with the filling cam part 6-3 along the circumference, and the bottom part is located below the material box 6-2 and connected to the material box 6-2, thereby realizing rotary follow-up gravity filling. Compared with the existing structure, the filling head 6-4 can be set on the entire outer circumference of the material box 6-2, which can significantly increase the number of simultaneous fillings and thus improve the filling efficiency.

[0040] A screw lifting mechanism 6-6 fixedly mounted on the frame 1 is provided at the bottom of the filling cam portion 6-3. A plurality of screw lifting columns 6-7 connected to the material box 6-2 are vertically provided on the upper surface of the filling table 6-1 along the circumferential direction. A driving motor 6-8 is fixedly mounted on the lower surface. The lower end of the screw lifting column 6-7 passes through the filling table 6-1 and is coaxially fixedly connected to a driven gear 6-9. The motor shaft of the driving motor 6-8 is coaxially fixedly mounted with a driving gear 6-10. The driving gear 6-10 and the driven gear 6-9 are located in the same horizontal plane and are connected by a chain transmission, so that both the filling cam portion 6-3 and the material box 6-2 can be lifted and lowered. The two are used in combination to meet the filling requirements of bottles of different height specifications, and have a wider range of uses.

[0041] The material box 6-2 includes a first material storage part 6-2-2 located in the center and a second material storage part 6-2-3 adjacent to the first material storage part 6-2-2 and higher than the first material storage part 6-2-2. The feeding assembly 6-5 includes a main feeding pipe 6-5-1 and a circulating feeding pipe 6-5-2 connected to the second material storage part 6-2-3 and a circulating outlet pipe 6-5-3 connected to the first material storage part 6-2-2. A circulating diaphragm pump 6-5-4 is provided between the circulating outlet pipe 6-5-3 and the circulating feeding pipe 6-5-2. A liquid level detector connected to the signal of the circulating diaphragm pump 6-5-4 is provided in the first material storage part 6-2-2. By setting up a material box 6-2 and a feeding assembly 6-5 with a special structure, the material is transported to the second material storage part 6-2-3 through the main feeding pipe 6-5-1, and overflows from the second material storage part 6-2-3 and flows to the first material storage part 6-2-2 at the lower part. The liquid level detector detects the liquid level change and controls the operation of the circulating diaphragm pump 6-5-4. The circulating diaphragm pump 6-5-4 then sucks the material in the first material storage part 6-2-2 into the second material storage part 6-2-3. Therefore, under the regulation of the feeding speed of the circulating diaphragm pump 6-5-4 and the main feeding pipe 6-5-1, the liquid level in the second material storage part 6-2-3 is ensured to be always at the highest point, thereby achieving a constant gravity filling speed and thus improving the gravity filling accuracy.

[0042] Considering that some materials are prone to foaming during filling, this embodiment optimizes the structure of the material box 6-2 and the filling head 6-4. Specifically, a first partition 6-2-4 is provided within the second material storage section 6-2-3. The top of the first partition 6-2-4 is higher than the top of the first material storage section 6-2-2, and the bottom is provided with a through hole, forming a first storage space and a second storage space that are adjacent and interconnected. The first storage space is adjacent to the first material storage section 6-2-2. The main feed pipe 6-5-1 and the circulating feed pipe 6-5-2 are both connected to the first storage space, and the filling head 6-4 is connected to the second storage space. The first partition 6-2-4 divides the second material storage section 6-2-3 into two interconnected storage spaces, allowing material to directly enter the first storage space and flow to the second storage space through the through hole at the bottom of the liquid surface, thereby reducing the generation of foam in the liquid surface area flowing to the filling head. Multiple second baffles 6-2-5 are evenly distributed along the circumference of the upper portion of the second storage space, dividing it into multiple interconnected storage units. The filling heads 6-4 are connected to corresponding storage units. The second baffles 6-2-5 reduce the flow of liquid within the rotating material tank 6-2, further reducing the generation of foam and stabilizing the flow rate to the filling heads 6-4.

[0043] The filling unit 6 also features a back-suction assembly 6-11, comprising an annular conduit 6-11-1 fixedly positioned below the material bin 6-2 and a main back-suction conduit 6-11-2 that extends through the material bin 6-2 in a sealed manner along its axis of rotation. The annular conduit 6-11-1 is circumferentially provided with multiple branch back-suction conduits 6-11-3. The filling head 6-4 is equipped with a feed nozzle 6-4-1 and a back-suction nozzle 6-4-2, each connecting the corresponding material storage unit to the branch back-suction conduits 6-11-3. The back-suction nozzle 6-4-2 is loosely sleeved around the feed nozzle 6-4-1, with its upper end in sealed contact with the feed nozzle 6-4-1 and its lower end higher than the feed nozzle 6-4-1. The lower end of the return suction main pipe 6-11-2 is connected to the annular pipe 6-11-1 through a pipe, and a rotary sealing joint 6-12 is connected between the upper end and the material box 2. The rotary sealing joint 6-12 is connected to the external suction device through a pipe, so that the foam generated during filling is sucked away through the return suction nozzle 6-4-2. The overall return suction component 6-11 can not only suck foam but also rotate synchronously with the material box 6-2 through the reasonable layout of the pipes, and the structure is simple.

[0044] Weighing unit 8 comprises a rotatable weighing plate 8-1 mounted on a frame. Multiple weighing stations 8-2 are evenly distributed along the circumference of weighing plate 8-1. Load cells 8-3 are connected to the bottom of each weighing station 8-2. The bottom of weighing plate 8-1 extends below frame 1 and is coaxially equipped with a drive gear and encoder. The encoder is connected to the finished product sorting unit 4. Filled and capped finished products are placed at each independent weighing station and weighed by the load cells at the bottom. If any unqualified product is found, the encoder records its location and sends it to the finished product sorting unit, enabling automatic weight check.

[0045] The finished product sorting section 4 includes a first output channel 4-1 and a second output channel 4-2, arranged side by side. The first output channel 4-1 docks with the weighing unit and has a notch near the entrance that connects to the second output channel. A reversible bottle guide baffle 4-3 is mounted on the first output channel 4-1 at the notch. The bottle guide baffle 4-3 comprises a plurality of horizontally arranged bottle retaining bars. One end of each bar is aligned and fixedly connected to a connecting rod 4-4 that is rotatably mounted outside the first output channel. The other end of each bar increases in length along the conveying direction, forming an inclined surface extending from the outside of the first output channel to the end of the notch. The other end of the connecting rod 4-4 is fixed with a cylinder 4-5. The piston rod of the cylinder 4-5 is vertically upward and hingedly connected to the connecting rod 4-4. Bottles from the first output channel are guided through the notch by the bottle guide baffle 4-3 to the second output channel, switching output channels and completing sorting. In addition, the sorting section 4 also includes a visual inspection unit 4-6 fixedly arranged on the side of the notch. The visual inspection unit 4-6 can remove unqualified products with crooked screw caps, thereby simultaneously removing unqualified products with unqualified screw caps and unqualified products with substandard filling. The integration is high, and the sorting of two types of unqualified products can be completed at the same sorting point, which reduces the inspection process and improves production efficiency.

[0046] This embodiment adds a weighing unit and a sorting unit on the basis of the existing structure. After the automatic filling and automatic capping are completed, weighing detection is directly carried out to determine whether the finished product filling weight meets the standard, and the sorting unit outputs qualified products and unqualified products separately. The entire process is completed automatically; at the same time, the filling unit sets up a filling table to place the transported empty bottles, and sets up a synchronously moving material box and filling head to realize follow-up gravity filling. The filling head can be set to cover the outer circumference of the material box. Compared with the existing structure, it can significantly increase the number of simultaneous fillings, thereby improving the filling efficiency.

It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
