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 precise and quantitative filling of liquid, semi-fluid, or powdered materials into packaging containers. It is used in industries such as food and beverage, pharmaceuticals, chemicals, and daily chemicals. 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 properties, container shapes, and production scales to ensure high-quality production.

[0003] Because barrels are placed in different positions when entering the production line, the orientation of the barrel mouth varies. Before filling the barrel, the barrel mouth must be accurately located. The current method used on production lines is to install a fixed barrel rotating device on the conveyor. When the barrel enters the production line, it is transported to the rotating device by the conveyor. The conveyor stops and the rotating device starts to rotate the barrel until the barrel mouth reaches the designated position. The rotating device stops and the conveyor starts to continue moving the barrel along the production line to the filling device.

[0004] While this method can locate the barrel opening, facilitating the smooth execution of subsequent filling operations, it still presents some challenges. The production line often has multiple barrels waiting to be transported for filling. Because the barrel rotary device is a standalone, fixed device, barrels at the front of the line have already completed filling and are waiting to be transported, while barrels at the back of the line are still waiting for the central barrel rotary device to rotate and locate the barrel opening. This results in barrels piling up and waiting, significantly impacting the efficiency of the entire production line.

[0005] Therefore, how to provide an efficient and convenient production line is a technical problem that those skilled in the art need to solve urgently. Summary of the Invention

DETAILED DESCRIPTION

[0040] To make the purpose, technical solutions, and advantages of this application more clear, 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 the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0041] As described in the background, barrels are placed in different positions when entering the production line, and the orientation of the barrel openings varies. Before filling the barrels, the barrel openings must be accurately located. The current method used on production lines is to install a separate, fixed rotating barrel device on the conveyor. When a barrel enters the production line and is transported to the rotating barrel device by the conveyor, the conveyor pauses, and the rotating barrel device starts to rotate the barrel until the barrel opening reaches the designated position. The rotating barrel device then stops, and the conveyor starts to continue moving the barrel along the production line to the filling device. While this method can locate the barrel opening to facilitate the smooth execution of subsequent filling operations, it still presents some problems. There are often multiple barrels on the production line waiting to be transported and filled. Because the rotating barrel device is an independent, fixed device, barrels at the front of the production line have already completed the filling operation and are waiting to be transported further, while barrels at the back of the production line are still waiting in line for the rotating barrel device in the middle to rotate and find the barrel openings. This leads to a backlog of barrels on the production line and a waiting time, which significantly affects the efficiency of the entire production line.

[0042] 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.

[0043] refer to Figures 1 to 10The 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 direction of the production line. The rotating barrel device 30 can abut the barrel body 10 and move along with the barrel body 10 along the 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 rotate the barrel body 10 in the circumferential direction so that the barrel mouth 100 of the barrel body 10 is rotated to a specified direction. The detection device 40 is used to detect the position of the barrel mouth 100. The screw capping device 50 is used to unscrew or tighten the barrel cap. The filling device 60 is used to pour materials into the barrel body 10. In this way, a filling production line for pouring materials into barrel bodies is formed.

[0044] The following is a detailed description of the scheme of the present application 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 direction of the production line; a rotating barrel device 30, which can abut the barrel body 10 and move along the direction of the production line with the barrel body 10 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.

[0045] 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 functions are provided on the side walls of the barrel bodies 10. The rotating barrel device 30 needs to avoid the folded ribs when working and chooses to contact the part of the barrel body 10 that does not have the folded ribs.

[0046] The rotating barrel device 30 can be a mechanical type, utilizing a combination of mechanical structures, such as gears and cams, to contact and apply force to the barrel body 10, causing the barrel body 10 to rotate during movement. This method is relatively simple in structure and low in cost, but has limitations in terms of speed and accuracy of barrel movement. Alternatively, the rotating barrel device 30 can be a pneumatic type, utilizing pneumatic components such as a barrel cover cylinder or a pneumatic motor to achieve the rotating barrel operation. This method is fast and efficient, but the pneumatic components have a high impact force, making the barrel body 10 susceptible to impact during the rotating and conveying operations, resulting in limited stability.

[0047] 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 rollers 310 and is used to drive the rollers 310 to rotate when the rolling surface of the rollers 310 abuts against the side wall of the barrel body 10, and utilize the friction between the rolling surface and the side wall to cause the barrel body 10 to rotate circumferentially.

[0048] The friction between the rolling surface of the roller 310 and the sidewall of the barrel 10 achieves circumferential rotation of the barrel 10, effectively resolving the issues of insufficient precision and stability previously encountered with the barrel rotating device. This allows for more precise control of the barrel 10's rotation angle, reduces shaking during the barrel rotation and transport process, and enhances the stability of the filling production line. Furthermore, the contoured plate 300 features a circular concave surface that better conforms to the shape of the barrel 10, ensuring good contact between the roller 310 and the barrel 10, further enhancing the barrel rotating effect.

[0049] 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 contact when in contact.

[0050] In a specific embodiment, there are two first driving members, both of which are servo motors and 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 .

[0051] In an optional embodiment, the conveying device 20 is a roller conveyor.

[0052] 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 to drive the roller 310 to move in a direction close to or away from the barrel body 10 .

[0053] In a specific embodiment, Figure 3 The figure shows a specific method for slidingly connecting the contour plate 300 and the fixed plate 320. The barrel rotating mechanism also includes a first guide rail 330, a first slider 340, and a second driving member 350. The first guide rail 330 is disposed at the bottom of the fixed plate 320. The first slider 340 is connected to the contour plate 300 at one end and slidably connected to the first guide rail 330 at the other end. The second driving member 350 is disposed in a groove structure of the fixed plate 320 and connected to the first slider 340. It is used to drive the first slider 340 to slide along the first guide rail 330, thereby driving the contour plate 300 toward or away from the barrel body 10. The second driving member 350 can be a servo motor.

[0054] Among them, when the contoured plate 300 moves toward the barrel body 10 and the roller 310 abuts 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 with which the roller 310 squeezes 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, avoiding poor barrel rotation caused by pressure greater than friction. When the force with which the roller 310 squeezes 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, avoiding too little pressure and the barrel body 10 being unable to rotate due to the loose fit between the roller 310 and the barrel body 10.

[0055] 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.

[0056] Preferably, due to the high cost of the mechanical transfer arm and the fact that 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 direction of operation 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 direction of operation of the production line.

[0057] It should be noted that the bottom frame of the rack 70 can also be provided with a second guide rail 700 in the direction of production line operation, with the conveying device 20 provided on the inner side of the bottom frame and the second guide rail 700 provided on the outer side, so that the sliding mechanism can move along the second guide rail 700. However, setting the second guide rail 700 on the bottom frame will cause maintenance difficulties. When a problem occurs with the conveying device 20, the staff must first remove the rotary barrel device 30 before repairing the conveying device 20. After the repair is completed, the rotary barrel device 30 must be installed again. Such repeated disassembly increases the difficulty of maintenance and is time-consuming and labor-intensive. In view of this problem and in view of the fact 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 rotary 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.

[0058] 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. 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. 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.

[0059] In a specific embodiment, Figure 3 As shown, the sliding mechanism further 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.

[0060] 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 the sliding mechanism.

[0061] In the process of rotating barrels, the barrel body 10 moves along the direction of the production line driven by the conveying device 20 and appears in the working area of ​​the rotating barrel device 30, that is, between the two rotating barrel 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 the four rollers 310. Then, the first driving members are started to drive the rollers 310 to rotate, and the friction force is used to rotate the barrel body 10 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 rotating barrel mechanism to move at the same speed as the barrel body 10 along the direction of the production line.

[0062] 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 effectively shortens the time of the entire production process and improves the work efficiency of the filling production line.

[0063] Preferably, reference Figure 1 、 Figure 3 and Figure 4As 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.

[0064] 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 respectively arranged on opposite sides of the filling surface and the line connecting the two coincides with the diameter of the filling surface.

[0065] In a specific embodiment, the detection device 40 uses a visual camera, which includes a body, a lens provided 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 the preset position relationship to determine the position of the barrel mouth 100 on the filling surface, or, 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.

[0066] 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 and filling operations.

[0067] 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.

[0068] 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) provided 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 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.

[0069] The detection element has a preset detection range. Because different types of barrels 10 have different barrel heights, if the detection device 40 does not touch the barrel when detecting the barrel opening of the front barrel, it will not change its height when detecting the barrel opening of the rear barrel. If the barrel height of the rear barrel is greater than that of the front barrel, there is a risk that the detection device 40 will touch the rear barrel. Therefore, a protective member 400 is provided on the periphery of the detection element. At the same time, when the protective member 400 touches the barrel, the fourth drive member will be activated in time to drive the protective member 400 away from the barrel, protecting the safety of the internal detection element.

[0070] In a specific embodiment, reference Figure 7 The 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. Each guide rod 420 is sleeved with an elastic member, which plays 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.

[0071] 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.

[0072] 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.

[0073] In a specific embodiment, the second plate 450 is fixed at the middle position of the connecting plate 80. This arrangement ensures that the position of the detection point of the detection device 40 is consistent with the position of the center of the rotating barrel, thereby ensuring the accuracy of the barrel mouth position detection.

[0074] 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 according to the position of the barrel mouth 100 at the filling surface provided by the detection device 40 to unscrew or tighten the barrel cover (not shown in the figure) that matches the barrel mouth 100; 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.

[0075] 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.

[0076] In a specific embodiment, Figure 8 As shown, the displacement device 90 is provided with two movable slides, and the capping device 50 includes a fifth driving member 500, a sixth driving member 510, a mounting plate 520, a rotating shaft 530 and a capping clamp 540; the mounting plate 520 is connected to one of the slides, and the capping device 50 can slide perpendicular to the running direction of the production line through the slide; the fifth driving member 500 is arranged on the top of the mounting plate 520, and one end of the rotating shaft 530 is connected to the output end of the fifth driving member 500, and the other end is connected to the capping clamp 540; the sixth driving member 510 is connected to the capping clamp 540, and is used to drive the capping clamp 540 to move toward the barrel mouth 100. When the capping device 50 receives the position of the barrel mouth 100, it moves to the top of the barrel mouth 100 through the displacement device 90, and the sixth driving member 510 is started to move the capping jaw 540 toward the barrel mouth 100 and clamp the capping jaw 540 on the barrel cover. The fifth driving member 500 is started to rotate the rotating shaft 530 to drive the capping jaw 540 to rotate synchronously and unscrew the barrel cover from the barrel mouth 100.

[0077] In a specific embodiment, Figure 8 As shown, the filling device 60 includes a material conveying mechanism and a tube 600. The feed end of the tube 600 is connected to the material conveying mechanism, and the middle section of the tube 600 is detachably connected to the other slide of the displacement device 90. When the lid is opened, the tube 600 is moved by the displacement device 90 to directly above the bunghole 100. The material conveying mechanism controls the tube 600 to disconnect from the slide and control the tube 600 to extend into the interior of the barrel 10, allowing the material to flow out through the discharge end of the tube 600.

[0078] In an optional embodiment, the fifth driving member 500 may be a servo motor, and the sixth driving member 510 may be a cylinder.

[0079] In a specific embodiment, Figure 9 and Figure 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 moving during filling, which may cause the filling operation to be unstable.

[0080] Among them, such as Figure 3 、 Figure 9 and Figure 10 As shown, when the barrel body 10 is lifted up, the contoured plates 300 on both sides of the barrel body 10 retract to separate the rollers 310 from the barrel body 10. When the barrel body 10 is filled, the contoured plates 300 on both sides of the barrel body 10 extend to abut the rollers 310 against the barrel body 10. At the same time, the rollers 310 are used to detect whether the position of the barrel body 10 has shifted due to the filling operation. If the position is correct, the subsequent lid locking operation is carried out.

[0081] Preferably, the capping device 50 and the filling device 60 are both arranged on the connecting plate 80 .

[0082] In combination with the above embodiments, it can be seen that the detection device 40 is also provided on the connecting plate 80. Specifically, Figure 6 Top view and Figure 9 、 Figure 10 As shown in the overall diagram, the capping device 50 and the filling device 60 are both located on one side of the connecting plate 80, and the detection device 40 is located on the other side of the connecting plate 80. In this way, the three are integrated on the connecting plate 80 and move together with the barrel body 10, making the transmission path of the barrel body 10 shorter during the detection, capping and filling operations, reducing the error and failure risks when the barrel body 10 is transferred between different processes, and realizing the parallel processing of barrel transfer, detection, capping, filling and capping in the conveying and filling processes. At the same time, it also realizes the compact layout of the equipment and reduces the occupation of work space.
