Description

Technical Field

[0001] The present application relates to the technical field of material filling, and in particular to a filling production line. Background Art

[0002] Material filling refers to the technology of accurately and quantitatively filling liquid, semi-fluid or powdered materials into packaging containers, which is applied to food and beverage, medicine, chemical and daily chemical industries. Modern filling technology integrates automation, sensors, precise metering and control systems to achieve efficient and high-precision filling operations, while meeting the needs of different material characteristics, container shapes and production scales to ensure high-quality production.

[0003] Since the barrels are placed in different positions when entering the production line, the barrel mouths are in different directions. Before the barrels are filled with materials, the barrel mouths must be located accurately. The current method used on the production line is to set a fixed barrel rotating device on the conveying device. When the barrel enters the production line and is transported to the barrel rotating device by the conveying device, the conveying device stops running, and the barrel rotating device starts to drive the barrel to rotate until the barrel mouth reaches the specified position. The barrel rotating device stops, and the conveying device starts to continue to drive the barrel to move along the production line to the filling device.

[0004] Although this method can locate the barrel mouth position for the smooth execution of subsequent filling operations, there are still some problems. There are often multiple barrels waiting to be transported and filled on the production line. Since the barrel rotating device is an independent fixed device, the barrels in front of the production line have completed the filling operation and are waiting to be transported, while the barrels at the back of the production line are still waiting in line for the barrel rotating device in the middle to rotate the barrels and find the barrel mouth, resulting in the accumulation and waiting of barrels on the production line, which greatly affects the work efficiency of the entire production line.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] As described in the background technology, since the barrels are placed in different positions when entering the production line, the barrel mouths of the barrels are in different positions. Before performing the material filling operation on the barrels, the barrel mouth position must be accurately found. The method currently adopted on the production line is to set a fixed rotating barrel device on the conveying device. When the barrel enters the production line and is transported to the rotating barrel device by the conveying device, the conveying device is suspended, and the rotating barrel device is started to drive the barrel body to rotate until the barrel mouth reaches the specified position. The rotating barrel device stops and the conveying device is started to continue to drive the barrel body to move along the production line to the filling device. Although this method can locate the barrel mouth position for the smooth execution of subsequent filling operations, there are still some problems. There are often multiple barrels waiting for transportation and filling on the production line. Since the rotating barrel device is an independent fixed device, the barrels in front of the production line have completed the filling operation and are waiting to continue to be transported. The barrels behind the production line are still waiting in line for the rotating barrel device in the middle to rotate the barrel to find the barrel mouth, resulting in the accumulation and waiting of barrels on the production line, which greatly affects the work efficiency of the entire production line.

[0023] Based on this, the present application provides a filling production line, which aims to solve the technical problems in the prior art that the position of the barrel rotating device is fixed, resulting in production line stagnation and barrel accumulation.

[0024] refer to Figures 1 to 10 The filling production line provided in the present application generally includes: a conveying device 20, which is used to drive the barrel body 10 to move along the running direction of the production line. A rotating barrel device 30, which can abut the barrel body 10 and move along with the barrel body 10 along the running direction of the production line when the barrel body 10 moves into the working area of ​​the rotating barrel device 30, and at the same time apply force to make the barrel body 10 rotate circumferentially, so that the barrel mouth 100 of the barrel body 10 rotates to a specified position. A detection device 40, which is used to detect the position of the barrel mouth 100. A capping device 50, which is used to unscrew or tighten the barrel cap. A filling device 60, which is used to pour materials into the barrel body 10. In this way, a filling production line for pouring materials into a barrel body is formed.

[0025] The scheme of the present application will be described in detail below in conjunction with the drawings in the specification. The present application provides a filling production line, including: a conveying device 20, used to drive the barrel body 10 to move along the running direction of the production line; a rotating barrel device 30, which can abut the barrel body 10 and move along with the barrel body 10 along the running direction of the production line when the barrel body 10 moves into the working area of ​​the rotating barrel device 30, and at the same time apply force to make the barrel body 10 rotate circumferentially, so that the barrel mouth 100 of the barrel body 10 rotates to a specified position.

[0026] It should be noted that the barrel 10 is as follows Figure 1 As shown, all barrel bodies 10 mentioned in this embodiment are cylindrical, and folded ribs with reinforcing effect are provided on the side wall surface of the barrel body 10. The rotating barrel device 30 needs to avoid the folded ribs when working, and chooses to contact the partial surface of the barrel body 10 without folded ribs.

[0027] Among them, the barrel rotating device 30 can adopt a mechanical barrel rotating device, which uses a combination of mechanical structures such as gears, cams, etc. to contact and apply force to the barrel body 10, so that the barrel body 10 rotates during the movement. This method has a relatively simple structure and low cost, but is limited in speed and accuracy of moving with the barrel. The barrel rotating device 30 can also adopt a pneumatic barrel rotating device, and pneumatic components such as barrel cover cylinders or pneumatic motors can realize barrel rotating operations. This method is fast and efficient, but the impact force of pneumatic components is large, and the barrel body 10 is easily impacted during barrel rotating operations and conveying operations, and the stability is general.

[0028] Preferably, in order to solve the technical problems of accuracy and stability of the above-mentioned rotating barrel device, this embodiment provides an improved rotating barrel device. Figure 2 and Figure 3 As shown, the rotating barrel device 30 includes a rotating barrel mechanism, which includes a first driving member (not shown in the figure), a contoured plate 300 and two rollers 310. The two rollers 310 are arranged at opposite ends of the contoured plate 300. The first driving member is connected to the roller 310 and is used to drive the roller 310 to rotate when the rolling surface of the roller 310 abuts against the side wall of the barrel body 10, and utilizes the friction between the rolling surface and the side wall to cause the barrel body 10 to rotate circumferentially.

[0029] Among them, the friction between the rolling surface of the roller 310 and the side wall surface of the barrel body 10 is used to realize the circumferential rotation of the barrel body 10, which effectively solves the problem of insufficient precision and stability of the aforementioned barrel rotating device, so that the rotation angle of the barrel body 10 can be more accurately controlled, and the shaking of the barrel body 10 during the barrel rotating and conveying process is also reduced, thereby enhancing the stability of the filling production line. In addition, the contoured plate 300 has an arc concave surface, which can better adapt to the shape of the barrel body 10, ensure good contact between the roller 310 and the barrel body 10, and further improve the barrel rotating effect.

[0030] In a specific embodiment, the axis of the roller 310 is parallel to the axis of the barrel body 10, so that the rolling surface of the roller 310 and the side wall surface of the barrel body 10 maintain complete fit when in contact.

[0031] In a specific embodiment, there are two first driving members, both of which are servo motors, which can be arranged at the bottom of the contoured plate 300 . The servo motors are connected one-to-one with the roller 310 to achieve high-precision control of the roller 310 .

[0032] In an optional embodiment, the conveying device 20 is a roller conveyor.

[0033] Preferably, reference Figure 2 and Figure 3 As shown, the rotating barrel mechanism further includes a fixed plate 320 , and the contoured plate 300 is slidably connected to the fixed plate 320 , and is used to drive the roller 310 to move in a direction close to or away from the barrel body 10 .

[0034] In a specific embodiment, Figure 3 As shown, a specific manner of sliding connection between the profiling plate 300 and the fixed plate 320 is provided. The barrel rotating mechanism further includes a first guide rail 330, a first slider 340 and a second driving member 350, wherein the first guide rail 330 is arranged at the bottom of the fixed plate 320, one end of the first slider 340 is connected to the profiling plate 300, and the other end is slidably connected to the first guide rail 330, and the second driving member 350 is arranged in the groove structure of the fixed plate 320, connected to the first slider 340, and used to drive the first slider 340 to slide along the first guide rail 330, so as to drive the profiling plate 300 to approach or move away from the barrel body 10; wherein the second driving member 350 can be a servo motor.

[0035] Among them, when the contoured plate 300 moves toward the barrel body 10 and the roller 310 abuts against the barrel body 10, the sliding characteristics between the contoured plate 300 and the fixed plate 320 can be used to adjust the electric driving force of the second driving member 350 to adjust the force when the roller 310 abuts against the barrel body 10. When the force of the roller 310 squeezing the barrel body 10 is too large, the contoured plate 300 can be appropriately moved away from the barrel body 10 to reduce the pressure of the roller 310 on the barrel body 10, thereby avoiding poor barrel rotation caused by pressure greater than friction. When the force of the roller 310 squeezing the barrel body 10 is too small, the contoured plate 300 can be appropriately moved closer to the barrel body 10 to increase the pressure of the roller 310 on the barrel body 10, thereby avoiding the pressure being too small and the roller 310 not fitting tightly against the barrel body 10, thereby causing the barrel body 10 to be unable to be rotated.

[0036] In an optional embodiment, the filling production line also includes a mechanical transfer arm connected to the rotating barrel device 30. The mechanical transfer arm is used to drive the rotating barrel device 30 to approach and abut the barrel body 10 and drive the rotating barrel device 30 to move along the barrel body 10 along the production line operation direction. At the same time, the rotating barrel device 30 applies force to make the barrel body 10 rotate circumferentially.

[0037] Preferably, since the cost of the mechanical transfer arm is relatively high, and both the mechanical transfer arm and the rotating barrel device 30 have a certain weight, there is a certain precision error problem during the movement process, which may cause the rotating barrel device 30 to be loosely fitted with the barrel body 10 or a speed difference. In order to solve this problem, a new structure for the rotating barrel device to move with the barrel is provided, referring to Figures 1 to 3 As shown, the filling production line also includes a frame 70, which includes a bottom frame and a top frame arranged relatively to each other, the bottom frame is provided with a conveying device 20, and the top frame is provided with a second guide rail 700 in the running direction of the production line; the rotating barrel device 30 also includes a sliding mechanism arranged corresponding to the rotating barrel mechanism, one end of the sliding mechanism is connected to the rotating barrel mechanism, and the other end is slidably connected to the second guide rail 700, which is used to drive the rotating barrel mechanism to move along the running direction of the production line.

[0038] It should be noted that the bottom frame of the rack 70 can also be provided with a second guide rail 700 in the running direction of the production line, and the conveying device 20 is provided on the inner side of the bottom frame, and the second guide rail 700 is provided on the outer side, so that the sliding mechanism moves along the second guide rail 700. However, setting the second guide rail 700 on the bottom frame will cause the problem of difficult maintenance. When there is a problem with the conveying device 20, the staff must first remove the rotating barrel device 30 before repairing the conveying device 20, and then install the rotating barrel device 30 after the repair is completed. Such repeated disassembly increases the difficulty of maintenance, which is time-consuming and labor-intensive. Considering this problem and considering that the top frame of the rack 70 is not fully utilized, the second guide rail 700 is provided at the top frame, and the rotating barrel device 30 is slidably connected to the second guide rail 700, which reduces the difficulty of maintenance and reasonably utilizes the working space of the rack 70.

[0039] In a specific embodiment, Figure 3 As shown, the sliding mechanism includes a fixed structure 360, a second slider 370 and a third driving member (not shown in the figure), one end of the fixed structure 360 ​​is connected to the rotating barrel mechanism, and the other end is connected to the second slider 370, and the second slider 370 is slidably connected to the second guide rail 700; the third driving member is used to drive the second slider 370 to slide along the second guide rail 700, and the third driving member can adjust the electric driving force to adapt to the moving speed of the barrel body 10, so that the sliding mechanism keeps in contact with the barrel body 10 and has the same speed as the barrel body 10 when moving with the rotating barrel mechanism.

[0040] In a specific embodiment, Figure 3As shown, the sliding mechanism also includes a reducer 380 connected to the third driving member, which is used to appropriately reduce the rotation speed of the third driving member and increase the torque; wherein the third driving member adopts a servo motor.

[0041] Preferably, reference Figure 1 As shown, the top frame has two opposite sides, each side is provided with a second guide rail 700, the number of rotating barrel mechanisms and the number of sliding mechanisms are both two, and each rotating barrel mechanism is slidably connected to the second guide rail 700 on the corresponding side through a sliding mechanism.

[0042] Among them, during the barrel rotating process, the barrel body 10 moves along the running direction of the production line driven by the conveying device 20 and appears in the working area of ​​the barrel rotating device 30, that is, between the two barrel rotating mechanisms. At this time, the second driving members 350 on both sides of the top frame are started to drive the contoured plate 300 to move toward the barrel body 10, so that the rollers 310 abut and squeeze the barrel body 10, and the barrel body 10 is surrounded by four rollers 310. Then, the first driving members are started to drive the rollers 310 to rotate, and the friction force is used to make the barrel body 10 rotate circumferentially so that the barrel mouth 100 rotates to the specified direction. At the same time, the third driving member drives the second slider 370 to slide along the second guide rail 700, so that the sliding mechanism drives the barrel rotating mechanism to move at the same speed as the barrel body 10 along the running direction of the production line.

[0043] To sum up, the position of the barrel rotating device 30 in the scheme is no longer fixed, but can move synchronously with the barrel body 10, so that the barrel rotating operation and the conveying operation can be carried out simultaneously, avoiding the production line stagnation and barrel body accumulation caused by the fixed position of the barrel rotating device 30 in the prior art method. The use of this parallel processing method can effectively shorten the time of the entire production process and improve the work efficiency of the filling production line.

[0044] Preferably, reference Figure 1 , Figure 3 and Figure 4 As shown, the barrel body has a filling surface, and the filling surface is provided with a positioning port 110 having a preset position relationship with the barrel mouth 100; the filling production line also includes a detection device 40 arranged above the filling surface and having a preset detection range, and the detection device 40 is used to determine the position of the barrel mouth 100 on the filling surface according to the positioning port 110 and the preset position relationship when the barrel body 10 rotates and the positioning port 110 appears within the preset detection range; or, the detection device 40 is used to determine the position of the barrel mouth 100 on the filling surface when the barrel body 10 rotates and the barrel mouth 100 appears within the preset detection range.

[0045] In a specific embodiment, the filling surface is a circular plane, and the preset position relationship between the barrel mouth 100 and the positioning port 110 is that the barrel mouth 100 and the positioning port 110 are arranged on opposite sides of the filling surface and the line connecting the two coincides with the diameter of the filling surface.

[0046] In a specific embodiment, the detection device 40 adopts a visual camera, which includes a body, a lens arranged on the body, a processor located inside the body, and a photosensitive sensor. The lens is always located above the filling surface and faces the filling surface. When the positioning port 110 appears within a preset detection range, the positioning port 110 is focused and imaged on the surface of the photosensitive sensor. The processor generates coordinate information of the barrel mouth 100 based on the image of the positioning port 110 and a preset position relationship to determine the position of the barrel mouth 100 on the filling surface. Alternatively, when the barrel mouth 100 appears within the preset detection range, the barrel mouth 100 is focused and imaged on the surface of the photosensitive sensor. The processor generates coordinate information based on the image of the barrel mouth 100 to determine the position of the barrel mouth 100 on the filling surface.

[0047] Among them, since the barrel body 10 is placed in different positions when entering the production line, the barrel mouth 100 of the barrel body 10 has different orientations, and the barrel rotating device 30 cannot obtain the position of the barrel mouth 100. Therefore, during the rotation and transportation of the barrel body 10, the detection device 40 is used to quickly find the position of the barrel mouth 100 to perform subsequent capping operations and filling operations.

[0048] It should be noted that when the position of the barrel mouth 100 is found, the roller 310 stops rotating, and at the same time, the barrel rotating mechanism moves along with the barrel body 10 along the running direction of the production line under the drive of the sliding mechanism.

[0049] Preferably, reference Figure 7 The detection device 40 includes a fourth driving member (not shown in the figure), a protective member 400 and a detection member (not shown in the figure) arranged in the internal cavity of the protective member 400. The fourth driving member is connected to the protective member 400 and is used to drive the protective member 400 to move away from the barrel body 10 when the protective member 400 touches the barrel body 10 until a preset distance is maintained between the protective member 400 and the filling surface, so as to protect the detection member.

[0050] Among them, the detection member has a preset detection range. Since different types of barrel bodies 10 have different barrel body heights, if the detection device 40 does not touch the barrel body when detecting the barrel mouth of the front barrel, the height position will not change when detecting the barrel mouth of the rear barrel. If the barrel body height of the rear barrel is greater than the barrel body height of the front barrel, there is a problem that the detection device 40 touches the rear barrel. Therefore, a protective member 400 is set on the periphery of the detection member. At the same time, when the protective member 400 touches the barrel body, the fourth driving member will be activated in time to drive the protective member 400 away from the barrel body to protect the safety of the internal detection member.

[0051] In a specific embodiment, reference Figure 7The detection device 40 also includes an installation group plate, a distance rod 410, two guide rods 420, an elastic member (not shown in the figure) sleeved on the guide rod 420, and a connecting member 430; the installation group plate includes a first plate 440, a second plate 450, and a third plate 460 vertically connected between the first plate 440 and the second plate 450; the distance rod 410 is connected between the first plate 440 and the second plate 450, and is arranged parallel to the third plate 460; the two guide rods 420 are also connected between the first plate 440 and the second plate 450, and are arranged at intervals, and each guide rod 420 is sleeved with an elastic member to play a role in buffering the movement of the protective member 400; one end of the connecting member 430 is connected to the bottom of the second plate 450, and the other end is connected to the protective member 400; the fourth driving member is installed on the back of the third plate 460.

[0052] In an optional embodiment, the fourth driving member is a cylinder, the elastic member is a spring, and the connecting member 430 is a hinge.

[0053] Preferably, reference Figure 1 and Figures 4 to 6 The filling production line further includes a connecting plate 80 for connecting the sliding mechanisms disposed on both sides of the top frame; the detection device 40 is disposed on the connecting plate 80 .

[0054] In a specific embodiment, the second plate 450 is fixed at the middle position of the connecting plate 80. Such an arrangement allows the position of the detection point of the detection device 40 to be consistent with the position of the center of the rotating barrel, thereby ensuring the accuracy of the barrel mouth position detection.

[0055] Preferably, reference Figures 4 to 6 as well as Figure 8 The filling production line also includes a capping device 50 arranged above the filling surface. The capping device 50 is used to move to the barrel mouth 100 to unscrew or tighten a barrel cover (not shown in the figure) matching the barrel mouth 100 according to the position of the barrel mouth 100 on the filling surface provided by the detection device 40; the filling production line also includes a filling device 60 arranged above the filling surface. The filling device is used to extend into the interior of the barrel body through the barrel mouth 100 to perform the filling operation after the barrel cover is unscrewed.

[0056] In a specific embodiment, Figures 4 to 6 as well as Figure 8 As shown, the filling production line further includes a displacement device 90, to which the capping device 50 and the filling device 60 are both connected. The displacement device 90 is used to drive the capping device 50 and the filling device 60 to move perpendicular to the running direction of the production line.

When the capping device 50 receives the position of the barrel mouth 100, it is moved to the top of the barrel mouth 100 through the displacement device 90, the sixth driving member 510 is started, so that the capping jaw 540 moves toward the barrel mouth 100 and the capping jaw 540 is clamped on the barrel cover, and the fifth driving member 500 is started, so that the rotating shaft 530 rotates to drive the capping jaw 540 to rotate synchronously, thereby screwing the barrel cover off the barrel mouth 100.

[0058] In a specific embodiment, Figure 8 As shown, the filling device 60 includes a material conveying mechanism and a tube body 600, the feeding end of the tube body 600 is connected to the material conveying mechanism, and the middle section of the tube body 600 is detachably connected to another slide of the displacement device 90. When the barrel cover is opened, the tube body 600 is moved to the top of the barrel mouth 100 through the displacement device 90, and the material conveying mechanism controls the tube body 600 to disconnect from the slide, and controls the tube body 600 to extend into the interior of the barrel body 10, so that the material flows out through the discharge end of the tube body 600.

[0059] In an optional embodiment, the fifth driving member 500 may be a servo motor, and the sixth driving member 510 may be a cylinder.

[0060] In a specific embodiment, Fig. 9 and Fig.10 As shown, the filling production line further includes a lifting device 120 for lifting the barrel body 10 when the filling device 60 performs the filling operation, so as to avoid the barrel body 10 still keeping moving during the filling, which may cause the filling operation to be unstable.

When the barrel body 10 is filled, the contoured plates 300 on both sides of the barrel body 10 are extended to make the rollers 310 contact the barrel body 10. At the same time, the rollers 310 are used to detect whether the position of the barrel body 10 is offset due to the filling operation. If the position is correct, the subsequent locking operation is performed.

[0062] Preferably, the capping device 50 and the filling device 60 are both arranged on the connecting plate 80 .

[0063] In combination with the above-mentioned embodiment, it can be known that the detection device 40 is also arranged on the connecting plate 80.
