Description

Technical Field

[0001] The invention relates to the technical field of filling machines, and in particular to a stepless distance-adjustable linear filling machine and a filling method. Background Art

[0002] A filling machine is an industrial packaging equipment. According to the different ways of feeding containers in the filling machine, the filling machine can be divided into linear filling machines and rotary filling machines. Among them, the linear filling machine has a wide range of technical applications and is therefore widely used in the industrial field.

[0003] In a linear filling machine, there are generally multiple filling valves arranged linearly, and multiple containers can be filled simultaneously through one filling action. Since multiple filling valves are usually fixedly connected to the machine body, the spacing between multiple filling valves is usually fixed. Therefore, most of the current linear filling machines are only suitable for batch filling of containers of a certain specification, resulting in poor adaptability of the equipment when facing containers of different specifications and different filling requirements.

[0004] In order to solve the problem that the distance between the filling valves cannot be adjusted in the linear filling machine, some linear filling equipment that can adjust the distance between the filling valves has emerged. For example, the patent application with the Chinese patent publication number CN119284814A discloses an edible oil filling equipment, through the cooperation between the multiple adjustment slots arranged in a fan shape on the adjustment plate and the multiple filling valves, so that the horizontal spacing between the multiple filling valves can be adjusted by moving in the multiple adjustment slots. Although the patent application can achieve the spacing adjustment between the filling valves, when the patent application adjusts the spacing of the filling valves in the conveying direction, it will also adjust the position of the filling valve in the direction orthogonal to the conveying direction, which will affect the positioning accuracy of the filling valve, easily affect the filling effect of the filling valve, and also require a larger adjustment space. In addition, the patent can only adjust a fixed distance and cannot achieve stepless adjustment. If different distances need to be adjusted, the adjustment plate needs to be replaced, which is not convenient to adjust and cannot be applied to more efficient filling operations.

[0005] Therefore, how to more accurately and efficiently adjust the distance between the filling valves in a linear filling machine is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0025] like Figures 1 to 8 As shown, the present invention provides a stepless linear filling machine, which is mainly used for filling materials into a container 9. In this embodiment, a packaging bottle is described as the container 9. In some other embodiments, the container 9 may also be other bottle bodies, box bodies, and other workpieces for containing materials.

[0026] For the convenience of explanation, in this embodiment, Figure 1 As shown, the first direction is the left-right direction, and the second direction is the front-back direction.

[0027] Specifically, Figures 1 to 3 As shown, the stepless distance-adjustable linear filling machine of the present invention comprises a storage device 1, a transport device 2, a filling device 3, a distance-adjusting device 4, a lifting device 5 and a control device. The transport device 2 transports a container 9 from left to right along a first direction. There are multiple filling devices 3, and the multiple filling devices 3 are all connected to the storage device 1. The lifting device 5 is connected to the distance-adjusting device 4. The control device is electrically connected to the storage device 1, the transport device 2, the filling device 3, the distance-adjusting device 4 and the lifting device 5, respectively.

[0028] More specifically, the transport device 2 transports the container 9 in the left and right direction, the lifting device 5 is located at the rear side of the transport device 2, the filling device 3 is located at the front side of the distance adjusting device 4, the filling device 3 is located at the upper side of the transport device 2, and the area below the filling device 3 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] In some embodiments, there are multiple filling devices 3, which may be two, three or more. In this embodiment, there are six filling devices 3. In some other embodiments, the number of filling devices 3 may be changed according to actual conditions.

[0031] In some embodiments, Figure 1 As shown, the steplessly adjustable linear filling machine further comprises a protective frame 6, and the material storage device 1, the transport device 2 and the lifting device 5 are all arranged on the protective frame 6, which has a certain protective function.

[0032] In some embodiments, Figure 2 As shown, the distance adjusting device 4 includes a distance adjusting support seat 41, a distance adjusting servo drive unit 42 and a distance adjusting linkage assembly. The distance adjusting linkage assembly is arranged on the distance adjusting support seat 41. Multiple filling devices 3 are connected to the distance adjusting linkage assembly. The distance adjusting servo drive unit 42 is connected to the distance adjusting linkage assembly to drive the multiple filling devices 3 to move synchronously along the first direction.

[0033] In some embodiments, the distance adjustment servo drive unit 42 is a servo motor, which can achieve stepless adjustment through servo drive and drive the distance adjustment linkage component to steplessly adjust the distance between each filling device 3.

[0034] In the actual filling process, it is usually necessary to fill containers 9 of different specifications. It is understandable that when filling containers 9 of different specifications and different batches, the distance between the bottle mouths of two adjacent containers 9 is different. By setting the distance adjusting device 4, the distance between each filling device 3 can be adjusted, so that it can adapt to containers 9 of different specifications and has better adaptability.

[0035] Specifically, during filling, the staff fills the material into the storage device 1, and the transportation device 2 transports the container 9 from left to right along the first direction to the bottom of the filling device 3. The control device transmits the corresponding electrical signal to the distance adjusting device 4 according to the different specifications of the containers 9. The distance adjusting device 4 drives the multiple filling devices 3 to move synchronously along the first direction, and keeps the same distance between each filling device 3 to ensure that each filling device 3 moves to the top of each container 9. The distance adjusting servo drive unit 42 is used to drive the distance adjusting linkage component to drive each filling device 3 to move synchronously, so as to realize stepless adjustment of the distance between each filling device 3, which is more convenient to adjust. There is no need to replace different adjustment mechanisms according to different specifications of containers 9. Only one set of distance adjusting device 4 is needed to complete the stepless adjustment, which can more accurately and efficiently adjust the distance between the filling devices 3 in the linear filling machine.

[0036] In some embodiments, Figure 2 , Figure 3 and Figure 8 As shown, the distance adjusting device 4 also includes a distance adjusting guide rail 43, which is arranged on the distance adjusting support seat 41 and extends along the first direction. The filling device 3 includes a filling support seat 31 and a filling valve 32, the filling support seat 31 is slidably connected to the distance adjusting guide rail 43, the filling valve 32 is arranged on the filling support seat 31, and the filling valve 32 is connected to the storage device 1.

[0037] Specifically, there are two distance-adjusting guide rails 43, both of which are fixedly connected to the distance-adjusting support seat 41, both ends of which extend in the left-right direction, and the two distance-adjusting guide rails 43 are arranged on the distance-adjusting support seat 41 at intervals in the vertical direction, and the filling support seat 31 is slidably connected to the distance-adjusting guide rails 43, so that the filling support seat 31 slides more smoothly, thereby improving the stability during distance adjustment.

[0038] In some embodiments, Figure 8 As shown, the filling device 3 also includes a filling detection unit 33, which is arranged at the bottom of the filling support seat 31. The filling detection unit 33 is used to detect whether there is a container 9 under the filling valve 32. If there is no container 9, the control device will not control the corresponding filling valve 32 to fill, so as to avoid wasting materials and causing pollution.

[0039] In some embodiments, the filling detection unit 33 is a photoelectric switch with a faster sensing speed.

[0040] In a specific embodiment, Figure 4 and Figure 5As shown, the distance adjustment linkage assembly includes a distance adjustment cam rod 44, which is rotatably connected to the distance adjustment support seat 41, and the distance adjustment cam rod 44 extends along the first direction. The distance adjustment servo drive unit 42 is connected to the distance adjustment cam rod 44, and the outer wall of the distance adjustment cam rod 44 is provided with a plurality of distance adjustment guide grooves 441, and the plurality of distance adjustment guide grooves 441 all extend along the axial direction of the distance adjustment cam rod 44 in a spiral manner. The filling support seat 31 is provided with a filling guide column 34, and the filling guide column 34 is inserted into the distance adjustment guide groove 441, and the filling guide column 34 can slide along the distance adjustment guide groove 441. Specifically, the distance-adjusting cam rod 44 extends in the left-right direction. When the distance between the filling devices 3 needs to be adjusted, the distance-adjusting servo drive unit 42 is started and drives the distance-adjusting cam rod 44 to rotate. The outer wall of the distance-adjusting cam rod 44 is provided with a plurality of spirally extending distance-adjusting guide grooves 441. The plurality of filling support seats 31 are provided with filling guide columns 34. The plurality of filling guide columns 34 are respectively and correspondingly plugged into the plurality of distance-adjusting guide grooves 441. It can be understood that when the distance-adjusting cam rod 44 rotates, the filling guide columns 34 will move along the distance-adjusting guide grooves 441, that is, the filling support seat 31 will move on the distance-adjusting guide rail 43, thereby realizing the distance-adjusting function. By driving the distance-adjusting cam rod 44 to rotate, all the filling devices 3 can be driven to move together. The distance adjustment is very convenient, and the synchronous distance adjustment of all the filling devices 3 can be realized. Moreover, a servo motor is used as the distance-adjusting servo drive unit 42. By servo drive, stepless adjustment can be realized, and the distance-adjusting linkage component can be driven to steplessly adjust the distance between each filling device 3.

[0041] In another specific embodiment, Figure 6As shown, the pitch-adjusting linkage assembly includes a pitch-adjusting screw 45, a pitch-adjusting nut 46, a pitch-adjusting guide rod 47, a pitch-adjusting scissors frame 48 and a plurality of pitch-adjusting sliding seats 49. The pitch-adjusting guide rod 47 is disposed on the pitch-adjusting support seat 41 and extends along the first direction. The plurality of pitch-adjusting sliding seats 49 are all slidably connected to the pitch-adjusting guide rod 47. The plurality of pitch-adjusting sliding seats 49 are connected through the pitch-adjusting scissors frame 48. The filling support seat 31 is connected to the pitch-adjusting sliding seat 49. The pitch-adjusting screw 45 is disposed on the pitch-adjusting support seat 41. The pitch-adjusting nut 46 is disposed on one of the pitch-adjusting sliding seats 49. The pitch-adjusting nut 46 is threadedly connected to the pitch-adjusting screw 45. The pitch-adjusting servo drive unit 42 is connected to the pitch-adjusting screw 45. Specifically, the distance-adjusting guide rod 47 extends in the left-right direction, and the distance-adjusting nut 46 is arranged on the distance-adjusting sliding seat 49 on the far left. When the distance between the filling devices 3 needs to be adjusted, the distance-adjusting servo drive unit 42 is started and drives the distance-adjusting screw rod 45 to rotate, and the distance-adjusting screw rod 45 drives the distance-adjusting sliding seat 49 on the far left to move. When the distance-adjusting sliding seat 49 on the far left slides on the distance-adjusting guide rod 47, the remaining distance-adjusting sliding seats 49 can be driven to move through the distance-adjusting scissors frame 48. It can be understood that if the distance between the filling devices 3 is to be increased, the remaining distance-adjusting sliding seats 49 can be driven to move to the right, and if the distance between the filling devices 3 is to be reduced, the remaining distance-adjusting sliding seats 49 can be driven to move to the left. It is very convenient to adjust, and the synchronous distance adjustment of all the filling devices 3 can be realized. In addition, a servo motor is used as the distance-adjusting servo drive unit 42. Through the servo drive, stepless adjustment can be realized, and the distance-adjusting linkage component can be driven to steplessly adjust the distance between each filling device 3.

[0042] In some embodiments, Figure 2 , Figure 3 and Figure 8 As shown, the filling device 3 also includes a filling feed pipe 35 , one end of which is connected to the filling valve 32 , and the other end of which is connected to the storage device 1 , so as to better guide the material in the storage device 1 to the filling valve 32 .

[0043] In some embodiments, Figure 2 and Figure 3 As shown, the storage device 1 includes a storage tank 11, a first feeding pipe 12, a second feeding pipe 13, a flexible corrugated pipe 14, a flow meter 15 and a booster pump 16, one end of the first feeding pipe 12 is connected to the storage tank 11, the other end of the first feeding pipe 12 is connected to one end of the second feeding pipe 13 through the booster pump 16, the other end of the second feeding pipe 13 is connected to one end of the flexible corrugated pipe 14, the other end of the flexible corrugated pipe 14 is connected to the filling device 3, and the flow meter 15 is arranged on the second feeding pipe 13.

[0044] Specifically, materials are stored in the storage tank 11 before use. When the filling valve 32 is not opened, the circulation valve of the booster pump 16 is opened and circulating pressurization is performed. When the filling valve 32 is filling, the circulation valve of the booster pump 16 is closed and circulating pressurization is not performed, thereby ensuring the normal transportation of materials.

[0045] Furthermore, the flexible corrugated pipe 14 is a stainless steel corrugated pipe. In order not to affect other parts of the drawings, the flexible corrugated pipe 14 in the drawings only shows a part of the pipe. One end of the flexible corrugated pipe 14 is connected to the second feeding pipe 13, and the other end of the flexible corrugated pipe 14 is connected to the filling feed pipe 35. The stainless steel bellows has deformation ability, and when the filling valve 32 moves, it can still achieve normal filling work, and has better adaptability.

[0046] In some embodiments, Figure 2 and Figure 3 As shown, the stepless distance-adjustable linear filling machine also includes a feed detection device 7, which includes a feed detection support seat 71 and a feed detection unit 72. The feed detection support seat 71 is arranged on the distance-adjusting device 4, and the feed detection support seat 71 is provided with a feed detection channel 73. The feed detection unit 72 is arranged on the side of the feed detection channel 73.

[0047] Specifically, when the container 9 is about to enter the filling area, it will first pass through the feeding detection channel 73, which will trigger the feeding detection unit 72, and the control device will count the containers 9 entering the filling area. When a certain number of containers 9 enter the filling area, the control device will control the transportation device 2 to pause the transportation of the containers 9, which is more intelligent.

[0048] In some embodiments, the incoming article detection unit 72 is a photoelectric switch with a faster sensing speed.

[0049] In some embodiments, Figure 2 and Figure 7 As shown, the stepless distance-adjustable linear filling machine also includes a baffle device 8, the number of which is two, and the two baffle devices 8 are arranged on the transport device 2 at intervals along the first direction, the baffle device 8 includes a baffle driving unit 81, a baffle support seat 82 and a baffle plate 83, the baffle support seat 82 is arranged on the transport device 2, the baffle driving unit 81 is arranged on the baffle support seat 82, and the baffle driving unit 81 is connected to the baffle plate 83 to drive the baffle plate 83 to move along the second direction, and the second direction is orthogonal to the first direction.

[0050] Specifically, the control device will count the containers 9 entering the filling area. When a certain number of containers 9 enter the filling area, the control device will control the transport device 2 to pause transporting the containers 9. At this time, the control device will transmit the corresponding electrical signal to the two baffle devices 8. The baffle drive unit 81 drives the baffle plate 83 to move toward the rear side and enter the transport path of the transport device 2. One of the baffle plates 83 is used to prevent the remaining containers 9 from entering the filling area, and the other baffle plate 83 is used to prevent the containers 9 in the filling area from leaving the filling area, which has a higher degree of intelligence.

[0051] In some embodiments, the stopper driving unit 81 is a linear cylinder. In some other embodiments, the stopper driving unit 81 may also be a linear motor or other component having a linear driving function.

[0052] In some embodiments, Figure 2 and Figure 7 As shown, the baffle device 8 also includes a baffle guide rail 84 and a baffle displacement unit 85, both of which are arranged on the transport device 2, and both ends of the baffle guide rail 84 extend in the left and right directions, the baffle support seat 82 is slidably connected to the baffle guide rail 84, and the baffle displacement unit 85 is connected to the baffle support seat 82 to drive the baffle support seat 82 to move left and right. It can be understood that containers 9 of different specifications occupy different spaces in the filling area. By setting the baffle guide rail 84 and the baffle displacement unit 85, the position of the baffle support seat 82 can be adjusted, that is, the position of the baffle plate 83 can be adjusted to adapt to containers 9 of different specifications, and the adaptability is better.

[0053] In some embodiments, the stopper displacement unit 85 is a servo cylinder. In some other embodiments, the stopper displacement unit 85 may also be a component having a linear drive function such as a servo motor.

[0056] The embodiment of the present invention further provides a filling method, which adopts the above-mentioned stepless distance adjustment linear filling machine to more accurately and efficiently adjust the distance between each filling device 3 in the linear filling machine, with higher adjustment efficiency and higher filling efficiency.

[0057] A filling method provided by an embodiment of the present invention comprises the following steps: S1. The staff fills the material into the storage device 1. Specifically, the staff will fill the material into the storage tank 11 in advance; S2, the transport device 2 transports the container 9 from left to right along the first direction to the bottom of the filling device 3; S3, the control device transmits corresponding electrical signals to the distance adjusting device 4 according to the containers 9 of different specifications, and the distance adjusting device 4 drives the multiple filling devices 3 to move synchronously along the first direction, that is, to move to the left or to the right at the same time, and keeps the same distance between the filling devices 3, ensuring that each filling device 3 moves to the top of each container 9; S4, the lifting device 5 drives each filling device 3 to move downward; S5, the filling device 3 fills the container 9. After the filling is completed, the lifting device 5 drives each filling device 3 to move upward, and the transportation device 2 continues to transport the container 9 along the first direction, that is, while sending away the filled container 9, the container 9 to be filled is transported to the filling area.

[0058] In some embodiments, in step S2, the transport device 2 transports multiple containers 9 from left to right, and allows the multiple containers 9 to pass through the incoming inspection channel 73 in sequence. When the container 9 passes through the incoming inspection channel 73, it will trigger the incoming inspection unit 72, and the control device will count the containers 9 entering the filling area. When a certain number of containers 9 enter the filling area, the control device will control the transport device 2 to pause transporting the containers 9, which is more intelligent.

[0059] Furthermore, in step S2, when a certain number of containers 9 enter the filling area, the control device will control the transport device 2 to pause transporting the containers 9. At this time, the control device will transmit the corresponding electrical signal to the two baffle devices 8, and the baffle driving unit 81 will drive the baffle plate 83 to move toward the rear side and enter the transport path of the transport device 2. One of the baffle plates 83 is used to prevent the remaining containers 9 from entering the filling area, and the other baffle plate 83 is used to prevent the containers 9 in the filling area from leaving the filling area, which is more intelligent.

[0060] In some embodiments, in step S4, the lifting device 5 drives each filling device 3 to move downward, so that the filling port of the filling valve 32 moves to the top of the container 9 or extends into the container 9. Specifically, in some cases, the filling port only needs to be moved to the top of the container 9 for filling, and in some cases, the filling port needs to be extended into the interior of the container 9 for filling, which can be selected according to actual needs.

[0061] In some embodiments, in step S5, if in step S4, the filling port only moves to the top of the container 9, the lifting device 5 no longer drives each filling device 3 to move upward; if the filling port has extended into the container 9, the lifting device 5 drives each filling device 3 to move upward so that the filling port leaves the container 9 workpiece; it can be understood that in step S4, if the filling port only moves to the top of the container 9, it will not affect the transportation of the container 9 by the transportation device 2, and the lifting device 5 does not need to drive each filling device 3 to move upward.

[0062] In some embodiments, in step S5, the flow meter 15 is used to detect the amount of material being filled. After detecting the rated amount of material being filled, the flow meter 15 transmits a corresponding electrical signal to the control device, and the control device controls the filling valve 32 to stop filling, which is more intelligent.

[0063] 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.
