Description

Technical Field

[0001] The present invention relates to the field of filling technology, and in particular to an automated filling production line. Background Art

[0002] During automatic filling, the packaging barrel moves to the bottom of the injection head, which is connected to the external material supply device to pour the material into the packaging barrel in a quantitative manner. Then the barrel mouth of the packaging barrel covers the barrel lid, and the barrel lid is tightened by rotating to complete the sealing.

[0003] The existing automatic filling production line can only fill a single type of packaging barrel, for example, it can only automatically fill 20KG round packaging barrels. When it is necessary to fill other packaging barrels such as 10KG round barrels, 20KG square barrels, 10KG square barrels, and rectangular barrels, it is not applicable. The production line adjustment is very complicated and cannot meet the requirements of flexible production lines. Setting up multiple production lines will occupy a large area, and the cost of production line supporting equipment is high and the utilization rate is low.

[0004] In the prior art, the problem of not being able to fill packaging barrels of various models needs to be solved. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide an automated filling production line in response to the above-mentioned technical deficiencies, which solves the problem in the prior art that multiple types of packaging barrels cannot be filled.

[0006] The technical solution adopted by the present invention is to provide an automated filling production line, comprising:

[0007] A supporting platform for supporting the packaging barrel, wherein the supporting platform has a filling area and a packaging area, and the packaging barrel moves from the filling area to the packaging area;

[0008] a camera module, disposed above the filling area, for taking pictures of the packaging barrels on the filling area and calculating the position of the barrel opening;

[0009] An injection head, which is arranged to be lifted above the filling area and located next to the camera module, is used to fill the packaging barrel with materials;

[0010] The centering device has two relatively movable mounting frames, each mounting frame is provided with a circularly rotating conveyor belt, and the two conveyor belts are clamped on both sides of the packaging barrel to transport the packaging barrel from below the camera module to below the injection head.

[0011] To further optimize this technical solution, the centering device further includes:

[0012] There are two linear drive mechanisms, and the linear drive mechanisms are used to drive the mounting frame to move.

[0013] Further optimization of this technical solution also includes:

[0014] A support frame is movably arranged on the mounting frame and is located on the inner side of the conveyor belt, and the support frame moves closer to or away from the conveyor belt;

[0015] There are a plurality of support rollers which are arranged in an array at intervals on the support frame. The support rollers are used to abut against the inner side of the conveyor belt and provide pressure for the conveyor belt to abut against the packaging barrel.

[0016] Further optimization of this technical solution also includes:

[0017] A compression spring, one end of which acts on the support frame and the other end of which acts on the mounting frame, is used to provide pressure for the support roller to abut against the inner wall of the conveyor belt.

[0018] To further optimize the technical solution, there are two centering devices, one of which is arranged above the filling area, and the other is arranged above the packaging area.

[0019] Further optimization of this technical solution also includes:

[0020] A sliding seat, slidably arranged above the packaging area;

[0021] A lifting drive mechanism is provided at the lower end of the sliding seat;

[0022] The vacuum suction cup is arranged at the moving end of the lifting drive mechanism and is used to place the barrel cover on the barrel mouth of the packaging barrel.

[0023] To further optimize the technical solution, the filling area is composed of a first conveyor belt, and the packaging area is composed of a second conveyor belt.

[0024] The beneficial effects of the present invention are:

[0025] 1. The camera can identify and locate the position of the barrel mouth. The data is used to control the movement of the two mounting brackets of the centering device. The mounting brackets are clamped on both sides of the packaging barrel, clamping and fixing the packaging barrel and moving it so that the barrel mouth of the packaging barrel corresponds to the position of the injection head. The conveyor belt then moves the packaging barrel to the bottom of the injection head, and the injection head completes the filling. It can adapt to packaging barrels of various shapes and sizes, and barrel mouths of different structures (the barrel mouths of some packaging barrels are not located in the center position), completing automatic filling.

[0026] 2. Differentiate the filling area and packaging area to realize automated operation of the assembly line. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] To simplify the drawings, only portions relevant to the invention are schematically depicted in each figure; they do not represent the actual structure of the product. Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one component with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0036] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] like Figure 1-6 As shown, an automated filling production line includes: a support platform 1 for supporting packaging barrels, the support platform 1 having a filling area 101 and a packaging area 102, and the packaging barrels move from the filling area 101 to the packaging area 102; a camera module 2, arranged above the filling area 101, for taking pictures of the packaging barrels on the filling area 101 and calculating the barrel mouth position; an injection head 3, which is arranged to be lifted above the filling area 101 and is located next to the camera module 2, for filling materials into the packaging barrels; a centering device 4, having two relatively movable mounting frames 401, each mounting frame 401 is provided with a conveyor belt 402 that is cyclically rotated, and the two conveyor belts 402 are clamped on both sides of the packaging barrel, for transporting the packaging barrel from under the camera module 2 to under the injection head 3.

[0039] The centering device 4 further includes: two linear drive mechanisms 403 , and the linear drive mechanisms 403 are used to drive the mounting frame 401 to move.

[0040] The filling area 101 is composed of a first conveyor belt 1011 , and the packaging area 102 is composed of a second conveyor belt 1021 .

[0041] During use, the packaging barrels are transported to the filling area 101 on the support platform 1 by the production line's transport equipment. After filling, the packaging barrels are moved to the sealing area 102 for capping. They are then moved from the support platform to the production line's transport equipment. The support platform 1 can be composed of a first conveyor belt 1011 and a second conveyor belt 1021. The production line's transport equipment can also be a conveyor belt that transports the packaging barrels in a single direction. Guide members and other means can be used on the transport equipment to guide the movement of the packaging barrels, ensuring that the packaging barrels enter the filling area 101 in a uniform posture.

[0042] In filling area 101, two mounting frames 401 are positioned relatively close together to clamp the packaging barrels. Conveyor belts 402 on either side clamp the barrels, securing the barrels. After centering device 4 secures the barrels, camera module 2 takes a picture and calculates barrel opening position parameters. Within centering device 4, two linear drive mechanisms 403 each drive a mounting frame 401 to move. Pressure changes after clamping the barrels can be detected using pressure sensors, for example. For example, pressure sensors can be installed at the connection between the moving ends of linear drive mechanisms 403 and mounting frames 401 to detect pressure. This can confirm whether conveyor belts 402 on either side secure the barrels. Alternatively, this can be determined using output sensor feedback from the linear drive mechanisms 403 themselves.

[0043] Camera module 2 captures the top of the packaging barrel and, through the control system, identifies and confirms the position of the through-hole. This allows for setting a reference position for the barrel opening. The path from the reference position to below the injection head 3 is known. By calculating the horizontal offset of the barrel opening in two axes relative to the reference barrel opening, the barrel's movement path can be determined, allowing the barrel opening to be moved below the injection head 3. Specifically, after camera module 2 identifies and calculates this, the control system controls the operation of centering device 4, controlling the extension and contraction of the two linear drive mechanisms 403. While maintaining the barrel clamped, this adjusts the barrel's position perpendicular to its direction of movement. The two conveyor belts 402 then rotate synchronously, optionally coordinating the movement of the first conveyor belt 1011 to reduce friction. This adjusts the barrel's position parallel to its direction of movement, achieving two-axis position adjustment and aligning the barrel opening with the injection head 3. The injection head 3 is then activated to complete filling. The camera module 2 identifies the barrel opening and calculates the relative position, which is conventional technology and can be implemented by those skilled in the art.

[0044] The filling volume of injection head 3 can be set based on the size of the barrels in each batch (i.e., only one size of barrel is filled within a batch). The injection head 3 can be raised and lowered to better align with the barrel opening and accommodate different barrel heights. The linear drive mechanism 403 can be a cylinder assembly or a linear motor. The conveyor belt and transport belt 402 can be driven by multiple motors.

[0045] Using conveyor belt 402 to contact the packaging barrel minimizes damage to the barrel's sidewalls and can accommodate square or round barrels. Conveyor belt 402 is long enough to accommodate barrels of varying lengths, eliminating the need for length adjustment. The contact surface between conveyor belt 402 and the barrel can be a timing belt structure, providing enhanced positioning and stable transport capabilities. This reduces the risk of insufficient barrel movement due to relative displacement, resulting in a failure to align the barrel opening with the injection head 3. Large-capacity barrels typically have larger barrel opening diameters, leading to significant redundancy in alignment accuracy.

[0046] Furthermore, it also includes: a support frame 5, which is movably set on the installation frame 401 and is located on the inner side of the conveyor belt 402. After the support frame 5 moves, it approaches or moves away from the conveyor belt 402; there are a plurality of support rollers 501, which are arranged in an interval array on the support frame 5. The support rollers 501 are used to abut against the inner side of the conveyor belt 402 to provide pressure for the conveyor belt 402 to abut against the packaging barrel.

[0047] It also includes: a compression spring 502 , one end of which acts on the support frame 5 and the other end acts on the mounting frame 401 , for providing pressure for the support roller 501 to abut against the inner wall of the conveyor belt 402 .

[0048] During use, the support rollers 501 enhance the stability of the conveyor belt 402 clamping against the packaging barrels, improving the displacement accuracy of the conveyor belts 402 on both sides when clamping and moving the packaging barrels. The support rollers 501 are vertically positioned inside the conveyor belt 402, near one side of the packaging barrel. The support frame 5 includes a guide rod 503, and the mounting frame 401 includes a guide seat 4011. The guide rod 503 slides within the guide seat 4011. A compression spring 502 is mounted on the guide rod 503. The compression spring 502 forces the support rollers 501 to abut the inner side of the conveyor belt 402 near the packaging barrel. The support rollers 501 are rotatably mounted on the support frame 5. When the conveyor belt 402 rotates, the support rollers 501 rotate passively, reducing frictional resistance. The support rollers 501 also ensure that when the conveyor belt 402 abuts against the packaging barrel, it applies force to the mounting frame 401, enabling more accurate determination of whether the conveyor belt 402 is clamping against the packaging barrel.

[0049] Furthermore, there are two centering devices 4 , one of which is disposed above the filling area 101 , and the other of which is disposed above the packaging area 102 .

[0050] It also includes: a sliding seat 6, which is slidably arranged above the packaging area 102; a lifting drive mechanism 601, which is arranged at the lower end of the sliding seat 6; and a vacuum suction cup 602, which is arranged at the moving end of the lifting drive mechanism 601 and is used to place the barrel cover on the barrel mouth of the packaging barrel.

[0051] During use, after filling is completed in the filling area 101, the first conveyor belt 1011 and the centering device 4 can move the packaging barrel to the packaging area 102. A centering device 4 is also installed above the packaging area 102. The two centering devices 4 are independently controlled and can each perform corresponding operations. When the packaging barrel moves from the filling area 101 to the packaging area 102, the two centering devices 4 can be in the same position, allowing the centering device 4 in the packaging area 102 to directly clamp and secure the packaging barrel. After the packaging barrel enters the packaging area 102, the filling area 101 can accept a new packaging barrel. The two conveyor belts 402 of the centering device 4 in the filling area 101 move away from each other and then close together to clamp the new packaging barrel without affecting the packaging operation in the packaging area 102.

[0052] In the packaging area 102, the packaging can be performed with the help of existing barrel cover packaging equipment, for example, the packaging is achieved by first placing a barrel cover on the barrel mouth and then rotating and tightening the barrel cover.

[0053] By lifting and moving the vacuum suction cup 602, the barrel cover can be placed at the barrel mouth to complete the lid-on operation. The sliding seat 6 can be driven by a screw structure to move in the moving direction of the packaging barrel, so that the vacuum suction cup 602 can absorb the barrel cover from the side. That is, an automatic conveying device for the barrel cover is set on the side to supply the barrel cover. Then, the vacuum suction cup 602 carries the barrel cover to the top of the barrel mouth, and after descending, the barrel cover is placed at the barrel mouth, the vacuum adsorption is removed, the barrel cover is released, and it is raised away. Then, the centering device 4 of the packaging area 102 can use the conveyor belt 402 to move the packaging barrel away from the vacuum suction cup 602, and then the barrel cover can be tightened with the help of the existing rotary capping equipment. The rotary capping equipment can also be connected to the barrel cover by vacuum adsorption, and then the barrel cover is driven to rotate and tighten by rotation. Of course, the lower end of the lifting drive mechanism 601 can also be provided with a drive motor to drive the vacuum suction cup 602 to rotate, completing the two actions of lid-on and tightening.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
