Description

Technical Field

[0001] The utility model relates to the technical field of filling, in particular to a multi-head independently controlled follow-up filling machine. Background Art

[0002] In modern industrial production, liquid filling technology is an important part of the packaging industry, and its automation and intelligence directly affect production efficiency and product quality. Especially in the fields of food, pharmaceuticals, chemicals, etc., higher requirements are placed on filling accuracy, filling speed and equipment stability. Traditional filling machines often have problems such as low filling accuracy, complex operation, and difficult equipment maintenance, which are difficult to meet the needs of modern industrial production. Therefore, the research and development and application of multi-head independent control follow-up filling machines came into being, becoming an effective way to solve these problems.

[0003] There are many automatic filling mechanisms on the market. For example, Chinese patent CN216190991U discloses a multi-head follow-up filling mechanism, which includes a filling frame and a mobile filling device connected to a PLC controller, and the mobile filling device is arranged above the filling frame; the mobile filling device includes a mobile driver, a filling device and an adjusting hand wheel, and the filling frame is provided with two parallel slide rails and a rack, and the rack is arranged in parallel between the two slide rails;

[0004] Although the patent can realize the automatic follow-up filling of the filling machine, improving the production efficiency; the filling machine can adjust the height of the filling head to meet the filling of packaging bottles of different heights; the filling machine can adjust the spacing of the bottle clamps to meet the filling of packaging bottles of different bottle mouth sizes;

[0005] However, this patent adopts unified control for material conveying and supply, that is, the amount of material conveyed by the same batch of packaging bottles is the same; but in actual use, due to problems such as pipeline blockage and piston rod stroke, there will be slight differences in the amount of material conveyed by different filling heads, affecting product quality.

[0006] Moreover, since the material conveying is controlled in the same way, it can only be used for packaging bottles of the same specifications; and if the packaging bottles of a different specification are changed, the material conveying volume needs to be readjusted, which makes the operation more complicated.

[0007] For this purpose, we propose a multi-head independently controlled follow-up filling machine. Utility Model Content

[0049] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0050] like Figure 1-Figure 5 As shown, this embodiment discloses a multi-head independently controlled follow-up filling machine, including a frame 500 and a feeding mechanism 400, a conveyor line 600, a follow-up drive structure 300, a bottle clamping mechanism 200, a filling head 100 and a material fullness identification structure arranged on the frame 500, wherein the number of the bottle clamping mechanism 200 and the filling head 100 are both multiple, and can be independently controlled, and the material input amount can be individually controlled according to the capacity of the packaging bottle, which can improve the material conveying accuracy and improve the product quality.

[0051] Specifically, according to Figure 1-Figure 5 Each component is described in detail.

[0052] like Figure 1 As shown, the feeding mechanism 400 in this embodiment includes a hopper, and a piston mechanism that is respectively connected to a plurality of filling heads 100 and used for feeding. The piston mechanism moves up and down to drive the material in the hopper to be transported to the filling head 100, and the feeding mechanism 400 and each filling head 100 are independently controlled by an independent piston mechanism, which is convenient for subsequent control of the material amount;

[0053] like Figure 1 and Figure 2 As shown, the follower drive structure 300 in this embodiment is connected to the frame 500 and can realize vertical movement. Its structure includes:

[0054] A fixed seat 301, which is connected to the lifting drive device and can achieve vertical movement;

[0055] There are multiple movable seats 302, which are connected to the bottle clamping mechanism 200, and the movable seats 302 are slidably connected to the fixed seat 301, and the fixed seat 301 is provided with a slide rail, and the movable seat 302 is slidably connected to the slide rail;

[0056] The second rotating device 303 is fixedly connected to the movable seat 302, and the second rotating device 303 drives the fixed seat 301 and the movable seat 302 to slide relative to each other through the gear rack assembly 304. Specifically, Figure 2 As shown, the driving end of the second rotating device 303 is connected to a rotatable gear, and a rack meshing with the gear is provided on the fixed seat 301, thereby realizing relative sliding, and with the rotation of the second rotating device 303, the bottle clamping mechanism 200 can be driven to move horizontally. In this embodiment, the moving direction of the bottle clamping mechanism 200 is consistent with the moving direction of the conveyor line 600, thereby realizing horizontal following movement, and at the same time, the rotation rate of the second rotating device 303 determines that the moving speed of the bottle clamping mechanism 200 is the same as that of the packaging bottles on the conveyor line 600.

[0057] like Figure 2-Figure 4 As shown, the bottle clamping mechanism 200 in this embodiment is multiple and horizontally slidably connected to the follow-up driving structure 300. The bottle clamping mechanism 200 has at least two functions, one of which is to clamp the packaging bottle (and can be used to weigh the packaging bottle) and drive the subsequent filling head 100 to move vertically, so as to extend into the packaging bottle for filling. The structure of the bottle clamping mechanism 200 includes:

[0058] The mounting frame 201 serves as a protective housing;

[0059] The bottle clamping cylinder 203 is connected to the lower end of the mounting frame 201 and is used to clamp the mouth of the packaging bottle;

[0060] In another embodiment, a first weighing structure is connected to the connection between the bottle clamping cylinder 203 and the mounting frame 201, which is used to weigh the packaging bottle, determine the material quantity, and automatically adjust the material quantity.

[0061] The screw rod 206 is rotatably connected to the mounting frame 201, and a connecting piece 207 is threadedly sleeved on the screw rod 206. Specifically, the mounting frame 201 is connected to the first rotating device 202, and the driving end of the first rotating device 202 is connected to the screw rod 206. The first rotating device 202 is electrically connected to the second photoelectric sensor 205 for controlling the height of the barrel 101.

[0062] In one embodiment, a filling head 100 is connected to the side wall of the connecting member 207. The filling head 100 includes a barrel 101 arranged parallel to the screw rod 206. A feeding port 102 is provided on the side wall of one end of the barrel 101, and the other end of the barrel 102 is open and used for discharging materials, that is, a discharging port. A driving rod 104 is provided in the barrel 101 and can be telescopically moved along the axial direction of the barrel 101. A blocking block 105 that can block the open side of the barrel 101 is connected to the driving rod 104. Specifically, the filling head 100 A telescopic device 103 is connected to the top, and the driving end of the telescopic device 103 is connected to the driving rod 104, the blocking block 105 is sleeved on the side wall of the driving rod 104, and the movable end of the driving rod 104 is connected to a material full identification structure, the material full identification structure is a liquid level sensor 106, which is used to identify the liquid level of the material in the packaging bottle, and the liquid level sensor 106 is electrically connected to the telescopic device 103. After identifying that the material has reached the liquid level, the blocking block 105 is driven by the telescopic device 103 to block the barrel.

[0063] like Figure 2-Figure 3 As shown, in order to facilitate identification of the relative positional relationship between the packaging bottle, the bottle clamping mechanism 200 and the filling head 100, the bottle clamping mechanism 200 in this embodiment further includes a first photoelectric sensor 204 and a second photoelectric sensor 205;

[0064] Specifically, the first photoelectric sensor 204 in this embodiment is connected to the fixing seat 301 through a bracket and is used to identify the position of the bottle mouth of the packaging bottle. The first photoelectric sensor 204 is electrically connected to the lifting drive device and can adjust the height of the bottle clamping mechanism 200.

[0065] The second photoelectric sensor 205 in this embodiment is connected to the mounting frame 201 and is used to identify the position of the barrel 101 .

[0066] The open side of the barrel 101 adopts a closed structure, and the blocking block 105 is wedge-shaped. The blocking efficiency is improved through the structural coordination of the blocking block 105 and the discharge port of the barrel 101. At the same time, due to the movement of the blocking block 105, the flow rate of the material can be controlled, so that the flow rate moves faster in the initial stage of filling, and when the packaging bottle is almost full, the flow rate moves slower, thereby improving the accuracy of weighing measurement and avoiding the influence of inertia on the weighing result due to too fast flow rate.

[0067] In this embodiment, the interior of the driving rod 104 is hollow for routing the liquid level sensor 106, and a mounting cover for protecting the liquid level sensor 106 is also connected to the driving rod 104. The mounting cover is annular, with an upper end connected to the driving rod 104 and an open lower end. The height of the mounting cover is greater than the height of the liquid level sensor, which can prevent the material from splashing onto the liquid level sensor during filling. At the same time, the sensitivity of the liquid level sensor needs to be set. In this embodiment, since the liquid level sensor will be immersed in the material after detecting that the material is full, the sensitivity of the liquid level sensor does not need to be too high to prevent the splashing material from causing the liquid level sensor to misjudge.

[0068] In another embodiment, a material fullness identification structure is provided at the connection between the bottle clamping cylinder 203 and the mounting frame 201. The material fullness identification structure is a first weighing structure. The first weighing structure can identify the total weight of the bottle clamping cylinder 203 and the packaging bottles clamped therein, and the first weighing structure is electrically connected to the telescopic device 103. After detecting that the weight reaches a predetermined weight, the telescopic device 103 drives the blocking block 105 to block the barrel, thereby achieving the effect of automatically controlling the feed amount.

[0069] In this embodiment, Figure 1 As shown, the conveyor line 600 is arranged directly below the filling head 100 , and packaging bottles are placed on the conveyor line 600 , and the moving route of the packaging bottles is arranged parallel to the moving route of the bottle clamping mechanism 200 .

[0070] In another embodiment, a plurality of carriers for fixing packaging bottles are provided on the conveyor line 600, and a material full identification structure is provided in the carrier, the material full identification structure is a second weighing structure, and the weighing structure is used to identify the total weight of the packaging bottles, and the second weighing structure is electrically connected to the telescopic device 103. After detecting that the weight reaches a predetermined weight, the telescopic device 103 drives the blocking block 105 to block the barrel, thereby achieving the effect of automatically controlling the feed amount.

[0071] To sum up, the utility model adopts multiple liquid level sensors and can automatically close the filling head 100 when the packaging bottle is full of materials, so that multiple filling heads 100 can be filled at the same time, and the multiple filling heads 100 are automatically and independently controlled, and the material feed amount can be independently controlled according to the size and capacity of the packaging bottle, thereby improving the filling accuracy, and at the same time the automation effect improves the product quality.
