Description

Technical Field

[0001] The present invention belongs to the filling technology field for use on a three-spin cap sealing production line, and in particular to a filling device and a filling method for use on a three-spin cap sealing production line. Background Art

[0002] A twist-off cap is a cap made of tinplate. A twist-off cap is also known as an easy-open cap, which is usually made of tinplate. Internationally standard ones include three-spin, four-spin, and six-spin. Due to low cost, good sealing performance, and the ability to withstand high-temperature sterilization, it is favored by the food industry. Now, there are more and more beverages using glass bottles as filling carriers in the market, which is also the demand of people for the quality of life. Whether it is fruit juice, mineral water, etc., there are various forms of glass bottle filling.

[0003] Generally, the filling device used on a three-spin cap sealing production line can only fill one kind of beverage. When it is necessary to fill beverages with multiple flavors or different types, the entire set of filling devices on the production line needs to be replaced, resulting in a relatively high machine procurement cost and a large floor area of the production line. It is not conducive to the production and processing of production lines with a relatively small volume of filled beverages. If the same set of filling devices is used, in order to prevent the mixing of beverages, it is necessary to thoroughly clean and disinfect the filling device after the filling of the previous beverage is completed, and the filling of the next beverage can only start after the filling of one beverage is completed. The whole process is time-consuming and the production efficiency is low.

[0004] Therefore, it is an urgent problem for most of the filling devices and filling methods used on the current three-spin cap sealing production lines to be able to fill at least two kinds of beverages without replacing the entire set of filling devices on a production line and to have a relatively high production line efficiency. Summary of the Invention

Detailed implementation manners

[0044] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features well known to those skilled in the art are not described.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] Refer to Figure 1-11 , the filling device used on the three-spin cap sealing production line includes a base 1, multiple groups of filling components, and multiple groups of liquid outlet components corresponding to the multiple groups of filling components. The multiple groups of filling components and liquid outlet components are arranged on the base 1;

[0047] The filling assembly includes a rotating assembly, a lifting assembly, and at least two filling tubes 2. The rotating assembly includes a rotating shaft 3 rotatably connected to the base 1. The rotating shaft 3 is vertically arranged, and at least two filling tubes 2 are evenly arranged around the rotating shaft 3. The lifting assembly includes a driving mechanism for driving at least two filling tubes 2 respectively, and the driving mechanism is installed on the rotating shaft 3. The rotating shaft 3 and the base 1 are rotatably connected through a rolling bearing. The rolling bearing supports the rotating shaft and the parts on the shaft, maintains the normal working position and rotational accuracy of the shaft. The rolling bearing is convenient for use and maintenance, has reliable operation, good starting performance, and has a relatively high load-bearing capacity at medium speeds. The rolling bearing can well support the rotatable rotating shaft 3 on the base 1.

[0048] The liquid outlet assembly includes a liquid outlet pipe 4 and a supporting mechanism. The liquid outlet pipe 4 includes a plurality of parallel liquid outlet channels 5. The number of liquid outlet channels 5 is the same as the number of at least two filling tubes 2. The supporting mechanism is used to support the liquid outlet pipe 4 so that the output end of the liquid outlet pipe 4 is located above the input end of the filling tube 2. Electromagnetic devices 6 are respectively provided at the output end of the liquid outlet pipe 4 and the input end of the filling tube 2, and the two electromagnetic devices 6 are respectively arranged as an electromagnetic coil and a magnet.

[0049] The filling tube 2 below the output end of the liquid outlet pipe 4 in the connection channel 16 is the filling tube 2 in the working position, which is used to fill the beverage bottle 7 on the filling track, and the remaining filling tubes 2 are the filling tubes 2 in the rest state.

[0050] On the basis of the above embodiment, the filling tube 2 includes a tube body 12, a hose 13, and a piston 14. A telescopic electric cylinder 15 connected to the piston 14 is provided on the tube body 12. A connection channel 16 is provided at the top of the tube body 12. The hose 13 is used to connect the liquid outlet pipe and the filling chamber 17 below the piston 14. A connection structure 18 is provided in the connection channel 16, and the output end of the liquid outlet pipe 4 is connected to the hose 13 through the connection structure 18. The telescopic electric cylinder 15 pushes the piston 14 to push the beverage in the filling chamber 17 into the beverage bottle 7 below the filling tube 2.

[0051] On the basis of the above embodiment, an electromagnetic device 6 is provided on the inner wall of the connection channel 16. When the output end of the liquid outlet pipe is inserted into the connection channel 16, the electromagnetic device 6 in the connection channel 16 is docked with the electromagnetic device 6 of the liquid outlet pipe.

[0052] The outer wall of the electromagnetic device 6 located at the output end of the outgoing liquid pipe 9 is set as a magnet, and the inner wall of the connecting channel 16 is set as an electromagnetic coil. Since the connecting channel 16 is arranged in the filling pipe 2, it is convenient to energize the electromagnetic coil. After the electromagnetic coil is energized, the iron core in the coil generates a magnetic force, which attracts the magnet on the outer wall of the liquid outlet pipe 4 at the upper end of the connecting channel 16 through the magnetic force, so that the output end of the liquid outlet pipe 4 cooperates with the connecting channel 16. The replacement of the filling pipe 2 and the filling of the filling pipe 2 with beverages are realized through the rotating assembly and the lifting assembly, and different filling pipes 2 are connected to the same rotating shaft 3, eliminating the need to replace the entire filling device, reducing the floor area occupied by multiple sets of filling devices corresponding to multiple beverages, and lowering the production cost. The output ends of the filling pipes 2 in multiple groups of filling assemblies correspond to the bottle mouths of multiple beverage bottles 7 on the track for conveying the beverage bottles 7. This track is a conventional conveying track on the filling production line, which conveys a fixed number of beverage bottles 7 downward to the filling pipe 2. After filling is completed, the filled beverage bottles 7 are conveyed under the three-spin capping device, and at the same time, a fixed number of unfilled beverage bottles 7 are conveyed under the corresponding filling pipe 2.

[0053] On the basis of the above embodiment, the liquid outlet assembly further includes a support frame 19. At least two parallel sliding rods 20 are provided on the upper part of the support frame 19. The support mechanism includes a support plate 21 and a return spring 22. The support plate 21 is slidably connected to the sliding rod 20. The return spring 22 is sleeved on the sliding rod 20 and is located below the support plate 21. The support plate 21 is used to support the liquid outlet pipe so that the output end of the liquid outlet pipe 4 is located above the input end of the filling pipe 2.

[0054] On the basis of the above embodiment, the liquid outlet pipe 4 includes an inner liquid outlet pipe 8 and an outer liquid outlet pipe 9. The outer liquid outlet pipe 9 is sleeved outside the inner liquid outlet pipe 8. The input ends of the inner liquid outlet pipe 8 and the outer liquid outlet pipe 9 are respectively connected to a liquid outlet pump 11 that is connected to a beverage box 10 containing two different beverages. The beverage boxes 10 containing two different beverages are closely connected. The inner liquid outlet pipe 8 passes through the beverage box 10 connected to the outer liquid outlet pipe 9 and is connected to another beverage box 10. A sealing structure is provided at the position where the inner liquid outlet pipe 8 penetrates the beverage box 10 connected to the outer liquid outlet pipe 9 to prevent the beverages in the two beverage boxes 10 from mixing due to the inner liquid outlet pipe 8 penetrating the box wall of the beverage box 10, which affects the quality of the production output. The liquid outlet pump 11 can extract the beverages in the beverage box 10 to provide raw materials for the filling of the filling pipe 2. It can also, when it is necessary to replace the filling pipe 2, pump the residual beverages in the liquid outlet channel 5 back to the beverage box 10 to prevent the residual beverages in the liquid outlet channel 5 from dripping onto the newly incoming filling pipe 2 at the working position, causing contamination to the filling pipe 2. The cooperation, connection structure 18 between at least two liquid outlet channels 5 of the liquid outlet pipe 4 and the rotatable filling pipe 2, and the electromagnetic device 6 ensure that the filling pipe 2 and the liquid outlet pipe will not be contaminated by the previous beverages when replacing the beverages to be filled, guaranteeing the filling quality of the beverage bottles 7, eliminating the need to replace the entire set of filling devices, and improving the production efficiency.

[0055] Based on the above embodiments, an electromagnetic device 6 is provided on the outer wall of the output end of the outgoing liquid pipe 9. The electromagnetic device 6 provided on the outer wall of the output end of the outgoing liquid pipe 9 is set as a magnet, which can magnetically attract the iron core in the energized electromagnetic coil in the connection channel 16, so that the interface between the liquid outlet pipe and the filling pipe 2 fits tightly, preventing the leakage of the liquid medicine from the interface during the filling process, and effectively ensuring the production quality.

[0056] Inside the inner liquid outlet pipe 8 is the liquid outlet channel 5 of the inner liquid outlet pipe 8, and between the inner liquid outlet pipe 8 and the outer liquid outlet pipe 9 is the liquid outlet channel 5 of the outer liquid outlet pipe 9. An annular baffle is provided on the outer wall of the output end of the inner liquid outlet pipe 8. When the liquid outlet pipe 4 is separated from the connection channel 16, the annular baffle effectively prevents the beverage in the liquid outlet pipe 4 from contaminating the output ports of the other liquid outlet channels 5.

[0057] As Figure 4 shown, at location A is the connection structure 18. The liquid outlet channel 5 of the inner liquid outlet pipe 8 and the liquid outlet channel 5 of the outer liquid outlet pipe 9 are connected to the hose 13 through different connection structures 18.

[0058] As Figure 7 and Figure 9 shown, the liquid outlet channel 5 of the outer liquid outlet pipe 9 is connected to the hose 13 through this connection structure 18; the connection channel 16 is vertically arranged at the upper part of the pipe body 12. The connection structure 18 of one of the filling pipes 2 includes a support block 33 and an isolation block 34. The support block 33 is fixedly connected to the lower part of the connection channel 16. The electromagnetic device 6 is provided on the support block 33 and closely adheres to the inner wall of the connection channel 16. The isolation block 34 is arranged in the middle of the support block 33. The isolation block 34 is an annular structure for cooperating with the annular baffle to form a sealed structure. A placement groove is formed inside the isolation block 34 for blocking the output end of the inner liquid outlet pipe 8. Part of the support block 33 around the isolation block 34 is provided with holes 32 for the beverage conveyed by the outer liquid outlet pipe 9 to enter the filling chamber 17 through the hose 13.

[0059] As Figure 8 and Figure 10 shown, the liquid outlet channel 5 of the inner liquid outlet pipe 8 is connected to the hose 13 through this connection structure 18; the connection structure 18 of the other filling pipe 2 includes a support block 33 and an isolation block 34. The support block 33 is arranged at the lower part of the connection channel 16. The electromagnetic device 6 is fixedly provided on the support block 33 and closely adheres to the inner wall of the connection channel 16. A hole 32 is provided at the middle position of the support block 33. This hole 32 is a circular hole 32 for connecting the inner liquid outlet pipe 8 and the hose 13. The isolation block 34 surrounds the hole 32. The space between the electromagnetic device 6 above the support block 33 and the isolation block 34 forms a placement groove, partially for blocking the output end of the outer liquid outlet pipe 9. The outer wall of the isolation block 34 closely adheres to the inner wall of the annular baffle to ensure the stability of the connection structure 18. Both the annular baffle and the outer liquid outlet pipe 9 are placed in the space between the isolation block 34 and the electromagnetic device 6.

[0060] The flow areas of the holes 32 communicating with the inner liquid outlet pipe 8 and the holes 32 communicating with the outer liquid outlet pipe 9 are basically the same to ensure the same speed of the beverage during the filling process.

[0061] A liquid outlet pipe 4 penetrates through the support plate 21 twice, so that the liquid outlet pipe 4 forms a U-shaped structure. This structure enables the support plate 21 to have a better supporting effect on the liquid outlet pipe 4, and can drive the liquid outlet pipe 4 to move up and down simultaneously when the support plate 21 is driven. When the lifting assembly drives the filling pipe 2 to move downward to fill the beverage bottle 7, the electromagnetic device 6 drives the liquid outlet pipe 4 to move downward. The support plate 21 is stressed unilaterally, causing the support plate 21 to move downward along the slide rod 20. Due to the strong suction force of the electromagnetic device 6, the support plate 21 presses down the return spring 22. Since the up and down movement stroke of the filling pipe 2 is short when filling the beverage bottle 7 with the beverage, the support plate 21 can move up and down with the filling pipe 2. In the present invention, the connection structure 18 of the liquid outlet pipe 4, the support plate 21, the slide rod 20 and the return spring 22 is designed such that when the lifting assembly drives the filling pipe 2 to move up and down, the liquid outlet pipe 4 can move smoothly with the filling pipe 2, avoiding the separation of the liquid outlet pipe 4 and the filling pipe 2, making the liquid outlet pipe 4 always above the connection channel 16 during the process of replacing the filling pipe 2, and also preventing the liquid outlet pipe 4 from being pulled by the lifting assembly during the filling process, improving the safety during the filling process.

[0062] As Figure 6 shown, a fixing plate is sleeved on the output end of the liquid outlet pipe 4. The two ends of the fixing plate are respectively connected to the support plate 21 and the magnet. The fixing plate can prevent the connection deviation caused by the deformation of the liquid outlet pipe 4 when the output end of the liquid outlet pipe 4 is connected to the connection channel 16. The outer side of the fixing plate and the inlet end of the connection channel 16 are both provided with conical inclined surfaces. When the output end of the liquid outlet pipe 4 enters the connection channel 16, the conical inclined surfaces can guide the output end of the liquid outlet pipe 4 to quickly reach the docking position, ensuring that the magnet and the electromagnetic coil are aligned and firmly connected. In the present invention, the design with the cooperation of the conical inclined surfaces enables the liquid outlet pipe 4 to be smoothly docked with the connection channel 16. Under the action of the magnetic force, the liquid outlet pipe 4 and the connection channel 16 are tightly connected, effectively preventing leakage during the beverage filling process and improving the production quality.

[0063] On the basis of the above-mentioned embodiments, a lifting groove 23 is provided inside the rotating shaft 3. The driving mechanism includes a lead screw 24, a nut 25 and a lifting seat 26. The lead screw 24 is fixed inside the lifting groove 23. The lead screw 24 is in threaded cooperation with the nut 25. The lifting seat 26 is fixedly connected to the nut 25. The filling pipe 2 is connected to the lifting seat 26. The lead screw 24 is driven by a motor to rotate. The nut 25 on the lead screw 24 is matched with the lead screw 24 through the balls inside the nut 25, so that the nut 25 rotates on the lead screw 24, converting the rotational fit into a linear motion. A nut seat is sleeved outside the nut 25. The lifting seat 26 is connected to the nut seat. The filling pipe 2 connected to the lifting seat 26 is driven by the lead screw 24, thereby realizing the filling of the beverage bottle 7. In the present invention, through the connection interface design between the liquid outlet pipe 4 and the filling pipe 2, and in cooperation with the rotating assembly for replacing the filling pipe 2, the type of beverage to be filled in the beverage bottle 7 can be replaced, and the automatic filling of the beverage bottle 7 to be filled is realized through the lifting assembly, improving the overall efficiency of filling the beverage bottle 7 for different beverages. When using the filling device of the present invention to fill the beverage bottle 7 for different beverages, there is no need to replace the entire set of filling devices used on the three-spin cap sealing production line, reducing the investment in production equipment and the floor area of the equipment, and reducing the production cost.

[0064] On the basis of the above-mentioned embodiments, the base 1 is provided with a fixing frame 27. The fixing frame 27 is provided with a rotating motor 28. A plurality of rotating gears 29 are provided on the output shaft of the rotating motor 28. One end of the rotating shaft 3 is rotatably connected to the base 1, and the other end is provided with a transmission gear 30. The transmission gear 30 is in gear engagement with the rotating gears 29.

[0065] On the basis of the above-mentioned embodiments, a placing frame 31 is further provided on the base 1. The placing frame 31 is a cover with an opening facing the rotating shaft 3, and is used to isolate the filling pipe 2 that does not need to work. When replacing the filling pipe 2, when the liquid outlet pipe 4 and the filling pipe 2 are separated, the rotating assembly drives the filling pipe 2 that has completed filling to rotate to the placing frame 31 for static placement, which can prevent the residual liquid medicine in the filling pipe 2 from dripping onto the filling production line, and can also prevent impurities such as dust from entering the unsealed and resting filling pipe 2.

[0066] The filling method using the filling device for the three-spin cap sealing production line described above includes the following steps:

[0067] Step 1: Stop the liquid outlet pump 11 connected to the working liquid outlet channel 5, cut off the power supply of the electromagnetic device 6, and the supporting mechanism drives the liquid outlet pipe 4 to be separated from the filling pipe 2;

[0068] Step 2: The rotating assembly drives the filling pipe 2 to rotate, rotates the next filling pipe 2 to be used under the liquid outlet pipe, and makes the connection channel 16 of the next filling pipe 2 to be used correspond to the output end position of the liquid outlet pipe 4;

[0069] Step 3: The electromagnetic device 6 is powered on, and the liquid outlet pipe 4 and the next filling pipe 2 to be used are connected under the action of magnetic force. The filling pipe 2 is connected to the corresponding liquid outlet pump 11 through another liquid outlet channel 5 of the liquid outlet pipe 4.

[0070] Step 4: The liquid outlet pump 11 extracts the beverage in the corresponding beverage box 10 and supplies it to the replaced filling pipe 2.

[0071] Step 5: The corresponding driving mechanism in the lifting assembly drives the replaced filling pipe 2 to move downward to fill the beverage bottle 7.

[0072] Step 6: After the above filling is completed, the filling pipe 2 moves upward, and the conveying track of the beverage bottle 7 moves the filled beverage bottle 7 out of the filling area, moves the beverage bottle 7 to be filled under the filling pipe 2, and the downward movement of the filling pipe 2 completes the filling of the beverage bottle 7 to be filled, and this process repeats until all the beverage bottles 7 to be filled are filled.

[0073] Step 7: Through the cooperation of the filling assembly and the liquid outlet assembly, the filling process of the beverage bottle 7 with different beverages can be completed.

[0074] The implementation principle of the present invention is as follows:
