[0002] A filling machine is a packaging equipment that can fill liquid into a container according to a predetermined amount. Since filling machines can complete the filling of most materials, they have been widely used in food, pharmaceutical, chemical and other processing industries.

[0003] In traditional filling machines, when filling, the container bottles usually stop waiting for filling, and the whole equipment needs to reserve more space to buffer the container bottles. If there are many filling valves, the equipment will be larger and require more space. In addition, when filling, traditional filling machines can only fill one bottle before filling the next one. In this way, the conveying device can only stop and wait for the filling to be completed before conveying, which is inefficient.

[0004] In order to solve the problem that traditional filling machines need to stop and wait for filling, some tracking filling machines have come into being. For example, the patent application with the Chinese patent publication number CN117430077A discloses a circular tracking automatic filling machine, which adopts the circular tracking automatic filling method. Through the filling positioning device, it can not only ensure that the bottle does not deviate or misalign with the filling head during the movement, but also return to the original position in time and quickly. Although this patent application can realize tracking filling to a certain extent, most companies currently use more efficient linear filling machines. This patent application is only applicable to circular filling machines, not to the more common linear filling machines. It is impossible to fill in large quantities and non-stop, and there is still a lot of room for improvement in filling efficiency.

[0028] Specifically, the conveying device 2 conveys the container workpiece 10 in the left and right direction, the lifting device 4 is located at the rear side of the conveying device 2, the filling device 5 is located at the front side of the following device 3, the filling device 5 is located at the upper side of the conveying device 2, and the area below the filling device 5 is the filling area.

[0029] In some embodiments, the control device is a PLC (Programmable Logic Controller). In some other embodiments, the control device may also be a control device such as an industrial computer.

[0030] Through the above scheme, the material cylinder 1 is used to store the material to be filled, the conveying device 2 conveys the container workpiece 10, and after the workpiece detection device 6 detects the container workpiece 10, the workpiece detection device 6 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the lifting device 4 and the filling device 5 respectively, and the lifting device 4 drives the following device 3 to drive the filling device 5 to move above the container workpiece 10, and the filling displacement component 54 drives the filling support seat 51 to move along the following track. The movement speed of the filling support seat 51 is consistent with the speed of the conveying device 2 conveying the container workpiece 10, and the filling clamping component 53 clamps the container workpiece 1 0, the filling valve 52 fills the container workpiece 10, and after the filling is completed, the filling clamping assembly 53 releases the bottle mouth of the container workpiece 10, the conveying device 2 continues to convey the container workpiece 10, and the filling device 5 continues to fill the next container workpiece 10. In this way, the conveying device 2 can continuously convey the container workpiece 10, and the container workpiece 10 does not need to stop to wait for filling. The filling device 5 can achieve synchronous filling under the guidance of the following device 3, and the filling work efficiency is higher. In addition, the filling clamping assembly 53 is also included in the filling device 5, which can improve the stability during filling and the filling accuracy is higher.

[0031] In some embodiments, the number of filling devices 5 is several, that is, it can be one, two, or more than three, which can effectively improve the filling efficiency. In this embodiment, the number of filling devices 5 is six. In some other embodiments, the number of filling devices 5 can be changed according to actual conditions.

[0032] In some embodiments, Figure 1 As shown, the tracking filling machine also includes a protective frame 7, and the material cylinder 1, the conveying device 2 and the lifting device 4 are all connected to the protective frame 7, which has a certain protective function.

[0033] In some embodiments, Figures 2 to 5 As shown, the filling displacement assembly 54 includes a filling displacement motor 541 and a filling displacement gear 542, the following device 3 also includes a following support seat 33 and a following rack 34, the following support seat 33 is connected to the lifting device 4, the following track and the following rack 34 are both arranged on the following support seat 33, the filling displacement motor 541 is arranged on the filling support seat 51, the filling displacement motor 541 is connected to the filling displacement gear 542, and the filling displacement gear 542 is meshed with the following rack 34.

[0034] Specifically, both ends of the follower rack 34 extend in the left-right direction, and the follower rack 34 is fixedly connected to the follower support seat 33. When the filling displacement motor 541 drives the filling displacement gear 542 to rotate, the filling displacement gear 542 can engage with the follower rack 34 and drive the filling support seat 51 to move in the left-right direction, thereby driving the filling valve 52 to move left and right following the container workpiece 10, thereby realizing tracking filling and effectively improving the filling work efficiency.

[0035] In some embodiments, Figure 5 As shown, the filling displacement assembly 54 also includes a first filling slider 543 and a second filling slider 544, and the following track includes a first following track 31 and a second following track 32. The first following track 31 is arranged on the front side of the following support seat 33, and the second following track 32 is arranged on the upper side of the following support seat 33 and is located on the rear side of the following rack 34. The first filling slider 543 and the second filling slider 544 are both arranged on the filling support seat 51, and the first filling slider 543 is slidably connected to the first following track 31, and the second filling slider 544 is slidably connected to the second following track 32. It can be understood that the first filling slider 543 and the second filling slider 544 are arranged on two different and non-parallel planes, which can prevent the filling support seat 51 from shaking, prevent the filling support seat 51 from tipping over, improve the stability of the filling support seat 51 during movement, and improve the stability and accuracy of filling.

[0036] In some embodiments, the filling displacement gear 542 is a helical gear, and the follower rack 34 is a matching helical rack. The helical gear and the helical rack are used for transmission, which has strong transmission force and smooth operation. At the same time, it has a high load-bearing capacity and can drive the entire filling support seat 51 to move more stably.

[0037] In some embodiments, Figure 2 As shown, the following device 3 further includes a following protection cover 35 , which is disposed above the following support seat 33 and can protect the filling displacement gear 542 and the following rack 34 .

[0038] In some embodiments, Figure 5 As shown, the filling clamping assembly 53 includes a filling lifting cylinder 531, a filling clamping cylinder 532 and a filling clamping block 533. The filling lifting cylinder 531 and the filling clamping cylinder 532 are both arranged on the filling support seat 51. The filling lifting cylinder 531 is connected to the filling valve 52, and the filling clamping cylinder 532 is connected to the filling clamping block 533. Specifically, there are two filling clamping blocks 533. The filling clamping cylinder 532 is respectively connected to the two filling clamping blocks 533 to drive the two filling clamping blocks 533 to approach each other to clamp the bottle mouth of the container workpiece 10. The filling lifting cylinder 531 can adjust the position of the filling valve 52 to drive the valve mouth of the filling valve 52 to enter or leave the container workpiece 10, so as to better perform filling.

[0039] In some embodiments, Figure 5 As shown, the filling clamping assembly 53 also includes a filling clamping connecting plate 534, and the filling clamping block 533 is connected to the filling clamping claw cylinder 532 through the filling clamping connecting plate 534. Specifically, the filling clamping connecting plate 534 is connected to the movable end of the filling clamping claw cylinder 532 by bolts, and the filling clamping block 533 is connected to the filling clamping connecting plate 534 by bolts. In actual use, filling clamping connecting plates 534 and filling clamping blocks 533 of different specifications can be replaced to adapt to container workpieces 10 of different specifications or different shapes, which has better adaptability.

[0040] In some embodiments, Figure 5 and Figure 6 As shown, the filling clamping assembly 53 also includes a bottle-stuck detection unit 535, a bottle-stuck detection mounting block 536 and a bottle-stuck detection column 537. The bottle-stuck detection mounting block 536 is arranged at the movable end of the filling clamping claw cylinder 532. The bottle-stuck detection unit 535 is arranged at one end of the bottle-stuck detection mounting block 536 away from the filling clamping claw cylinder 532. The bottle-stuck detection column 537 is movably connected to the bottle-stuck detection mounting block 536. The bottle-stuck detection unit 535 is a U-groove type photoelectric sensor. One end of the bottle-stuck detection column 537 can trigger The bottle jam detection unit 535 and the other end of the bottle jam detection column 537 can touch the outer wall of the filling clamping claw cylinder 532. Specifically, in a normal state, one end of the bottle jam detection column 537 protrudes from the movable end of the filling clamping claw cylinder 532, and the other end of the bottle jam detection column 537 will not trigger the bottle jam detection unit 535. When the filling clamping block 533 clamps the container workpiece 10, the movable end of the filling clamping claw cylinder 532 will move toward the direction close to the filling clamping claw cylinder 532, and the bottle jam detection column 537 will also move toward The bottle jam detection column 537 moves in the direction close to the filling clamp cylinder 532 but does not touch the outer wall of the filling clamp cylinder 532. However, when the filling clamp block 533 clamps the container workpiece 10, if the container workpiece 10 is not clamped, the movable end of the filling clamp cylinder 532 will move in the direction close to the filling clamp cylinder 532 and can touch the outer wall of the filling clamp cylinder 532. The bottle jam detection column 537 will also move in the direction close to the filling clamp cylinder 532 and touch the outer wall of the filling clamp cylinder 532. After touching the outer wall of the filling clamping claw cylinder 532, it will move towards the direction close to the bottle jamming detection unit 535 and trigger the bottle jamming detection unit 535. At this time, it means that the filling clamping block 533 does not clamp the container workpiece 10, that is, the filling clamping block 533 is empty. The bottle jamming detection unit 535 transmits the corresponding electrical signal to the control device, and the control device controls the corresponding filling valve 52 not to perform filling work, so as to prevent material leakage from polluting the working environment and also prevent material waste, which is more intelligent.

[0041] In some embodiments, Figures 2 to 5As shown, the filling device 5 also includes a filling feed pipe 55 , one end of which is connected to the filling valve 52 , and the other end of which is connected to the material cylinder 1 , so as to better guide the material in the material cylinder 1 to the filling valve 52 .

[0042] In some embodiments, Figures 1 to 4 As shown, the tracking filling machine also includes a feeding device 8, which includes a first feeding pipe 81, a second feeding pipe 82, a flexible corrugated pipe 83, a flow meter 84 and a booster pump 85. One end of the first feeding pipe 81 is connected to the material cylinder 1, and the other end of the first feeding pipe 81 is connected to one end of the second feeding pipe 82 through the booster pump 85. The other end of the second feeding pipe 82 is connected to one end of the flexible corrugated pipe 83, and the other end of the flexible corrugated pipe 83 is connected to the filling valve 52. The flow meter 84 is arranged on the second feeding pipe 82.

[0043] Specifically, before use, materials are stored in the material cylinder 1. When the filling valve 52 is not opened, the circulation valve of the booster pump 85 is opened and circulating pressurization is performed. When the filling valve 52 is filling, the circulation valve of the booster pump 85 is closed and circulating pressurization is not performed, thereby ensuring the normal transportation of materials.

[0044] Furthermore, the flexible corrugated pipe 83 is a stainless steel corrugated pipe, one end of the flexible corrugated pipe 83 is connected to the second feed pipe 82, and the other end of the flexible corrugated pipe 83 is connected to the filling feed pipe 55. The stainless steel corrugated pipes have deformation capabilities, and when the filling valve 52 moves, normal filling work can still be achieved, and the adaptability is better.

[0045] In some embodiments, Figures 1 to 3 As shown, the tracking filling machine also includes a bottle separation device 9, which includes a bottle separation displacement component 91 and two bottle separation limit components 92. The bottle separation displacement component 91 is arranged at the conveying start end of the conveying device 2, and the bottle separation displacement component 91 is respectively connected to the two bottle separation limit components 92 to drive the two bottle separation limit components 92 to approach each other or move away from each other. Specifically, the bottle separation displacement component 91 can drive the two bottle separation limit components 92 to approach each other and clamp the container workpiece 10, thereby controlling the speed and number of the container workpiece 10 entering the filling area, so as to adjust the distance between two adjacent container workpieces 10.

[0046] In some embodiments, Figure 7 As shown, the bottle separation displacement assembly 91 includes a bottle separation displacement motor 911, a bottle separation screw rod 912 and two bottle separation displacement support seats 913. The bottle separation displacement motor 911 is connected to the two bottle separation displacement support seats 913 through the bottle separation screw rod 912. The two bottle separation limit assemblies 92 are respectively arranged on the two bottle separation displacement support seats 913, which can more smoothly drive the two bottle separation limit assemblies 92 to approach each other and clamp the container workpiece 10.

[0047] In some embodiments, Figure 7 As shown, the bottle separation limit assembly 92 includes a bottle separation limit support seat 921, a bottle separation limit synchronous belt 922, a bottle separation limit synchronous gear 923 and a bottle separation limit motor 924. The bottle separation limit support seat 921 is connected to the bottle separation displacement assembly 91, and the bottle separation limit motor 924 is arranged on the bottle separation limit support seat 921. The bottle separation limit motor 924 is connected to the bottle separation limit synchronous gear 923, and the bottle separation limit synchronous belt 922 is wound around the bottle separation limit synchronous gear 923. The bottle separation limit support seat 921 is connected to the bottle separation displacement support seat 913. The machine 924 drives the bottle separation limiting synchronous belt 922 to rotate. There is a speed difference between the rotation speed of the bottle separation limiting synchronous belt 922 and the conveying speed of the conveying device 2. The speed of the container workpiece 10 located between the bottle separation limiting synchronous belt 922 will be slower than the speed of the container workpiece 10 in the filling area. Therefore, after the container workpiece 10 leaves the bottle separation limiting synchronous belt 922, there will be a certain distance between it and the previous container workpiece 10, thereby separating each container workpiece 10, so that each container workpiece 10 can enter the filling area more orderly.

[0048] In some embodiments, Figures 1 to 3 As shown, the conveying device 2 includes a conveying frame 21, a conveying motor 22, a conveying transmission assembly and a conveyor belt 23. The conveying motor 22 is arranged on the conveying frame 21, the conveying motor 22 is connected to the conveying transmission assembly, and the conveying transmission assembly is connected to the conveyor belt 23. Specifically, the conveying transmission assembly is a chain sprocket transmission component, and the conveying is carried out by the conveyor belt 23, so that the conveying is smoother.

[0049] In some embodiments, Figures 1 to 4 As shown, the lifting device 4 includes a lifting frame 41, a lifting motor, a lifting transmission assembly and a lifting column 42. The lifting motor is arranged on the lifting frame 41, the lifting motor is connected to the lifting transmission assembly, the lifting transmission assembly is connected to the lifting column 42, and the lifting column 42 is connected to the following device 3. Specifically, the lifting transmission assembly is a screw transmission component, which makes the lifting process of the lifting column 42 smoother.

[0050] In some embodiments, Figures 1 to 3As shown, the workpiece detection device 6 includes a workpiece detection support seat 61 and two workpiece detection units 62. The workpiece detection support seat 61 is provided with a workpiece detection channel. The two workpiece detection units 62 are respectively located on both sides of the workpiece detection channel. When the container workpiece 10 is about to enter the filling area, it will first pass through the workpiece detection channel and trigger the workpiece detection unit 62. At this time, the container workpiece 10 has left the bottle separation device 9. The moving speed of the container workpiece 10 is the conveying speed of the conveying device 2. After the container workpiece 10 triggers the workpiece detection unit 62, the workpiece detection unit 62 transmits the corresponding electrical signal to the control device. The control device controls the filling device 5 to move with the container workpiece 10, and filling is performed simultaneously during the movement. The filling efficiency is higher and the occupied space of the entire filling machine can also be reduced.

[0051] In some embodiments, the workpiece detection unit 62 is a photoelectric switch with a faster sensing speed.

[0052] The embodiment of the present invention further provides a filling method, which uses the above-mentioned tracking filling machine to achieve higher filling efficiency and higher filling accuracy.

[0053] An embodiment of the present invention provides a filling method, comprising the following steps: S1, the conveying device 2 conveys the container workpiece 10; S2, after the workpiece detection device 6 detects the container workpiece 10, the workpiece detection device 6 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the lifting device 4 and the filling device 5 respectively, and the lifting device 4 drives the following device 3 to drive the filling device 5 to move above the container workpiece 10; S3, the filling displacement assembly 54 drives the filling support seat 51 to move along the following track, the movement speed of the filling support seat 51 is consistent with the speed of the conveying device 2 conveying the container workpiece 10, the filling clamping assembly 53 clamps the bottle mouth of the container workpiece 10, and the filling valve 52 fills the container workpiece 10; S4 , after the filling is completed, the filling clamping assembly 53 releases the bottle mouth of the container workpiece 10 , the conveying device 2 continues to convey the container workpiece 10 , and the filling device 5 continues to fill the next container workpiece 10 .

[0054] In some embodiments, step S1 also includes the following steps: the conveying device 2 conveys the container workpiece 10 from left to right, and passes through the bottle separation device 9 before reaching the workpiece detection device 6, so that the container workpiece 10 is separated into a uniformly spaced state before entering the filling area, so that filling can be carried out in a more organized manner.

[0055] In some embodiments, in step S2 , the preset height of the lifting device 4 can be adjusted according to the container workpiece 10 of different specifications, so that the filling clamping block 533 of the filling device 5 can just clamp the bottle mouth of the container workpiece 10 .

[0056] In some embodiments, in step S4, the flow meter 84 is used to detect the amount of material being filled. After detecting the rated amount of material being filled, the flow meter 84 transmits a corresponding electrical signal to the control device, and the control device controls the filling valve 52 to stop filling, which is more intelligent.

[0057] In some embodiments, the number of filling devices 5 is six. Before filling, the six filling devices 5 are arranged on the following track. It can be understood that the six filling devices 5 each have a fixed initial position of their own. After the first container workpiece 10 enters the filling area and the workpiece detection device 6 detects the first container workpiece 10, the workpiece detection device 6 transmits the corresponding electrical signal to the control device, and the control device transmits the corresponding electrical signal to the lifting device 4. The lifting device 4 drives all the filling devices 5 to move to the top of the filling area, wherein the filling device 5 located on the far right is not directly above the first container workpiece 10 at this time, but the distance between the initial position of the filling device 5 located on the far right and the workpiece detection device 6 is determined. The time when the container workpiece 10 reaches the far right filling device 5 can be determined by the distance and the conveying speed of the conveying device 2. After the time has passed, the filling device 5 starts and clamps the bottle mouth of the container workpiece 10. While completing the clamping action, the filling device 5 will also move to the right at the same speed as the conveying device 2 on the following track. After completing this clamping action, if the bottle jam detection unit 535 does not detect that the filling clamping block 533 is empty, it means that the clamping is in place, and the filling valve 52 is opened for filling. After the filling is completed, the filling device 5 returns to the initial position. Similarly, each filling device 5 performs tracking filling in this way. In this way, the conveying device 2 can continuously convey the container workpiece 10, and the container workpiece 10 does not need to stop to wait for filling. The filling device 5 can achieve synchronous filling under the guidance of the following device 3, and the filling work efficiency is higher. In addition, the filling device 5 also includes a filling clamping assembly 53, which can improve the stability during filling and the filling accuracy is higher.

[0058] It is worth noting that the number of filling devices 5 can be changed according to actual conditions, and the distance between two adjacent filling devices 5 can also be changed. The moving distance of each filling device 5 is basically constant. Therefore, the distance between two adjacent filling devices 5 can be adjusted according to this constant moving distance to ensure that one filling device 5 will not hit another filling device 5 when returning to the initial position after filling, thereby preventing safety accidents.

[0059] The above descriptions are only some embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
