Description

Technical Field

[0001] This invention relates to the field of intelligent filling machines, and in particular to a method for opening packaging barrels without prior recognition of the barrel lid. Background Technology

[0002] Before filling a packaging drum, the filling machine needs to open the drum. The typical preparation process involves first identifying the position of the drum lid, then using a drum-rotating mechanism to rotate the drum and position the lid, followed by the opening mechanism to open the lid. Some machines omit the drum-rotating step, directly conveying the drum to the opening mechanism via a roller conveyor. There, an image acquisition and recognition device identifies the lid, and the opening mechanism locates the lid's coordinates to open it.

[0003] The two methods described above are the most common lid-opening procedures, which involve image recognition of the lid. However, image acquisition, recognition, and calculation require relatively advanced equipment.

[0004] For example Figure 1 The packaging barrels shown can be opened using conventional procedures, but if multiple workstations need to open them simultaneously, a single image acquisition and recognition device is clearly insufficient. Conventional opening methods would require a separate image acquisition and recognition device for each workstation, significantly increasing the operational costs.

[0005] Figure 1 The packaging barrel 10 shown has an opening 11 that protrudes from the top surface, and the opening 11 is not concentrically positioned with the packaging barrel 10. Given this structural feature, designing a method to open the barrel without an image acquisition and recognition device would undoubtedly significantly reduce production costs in the filling industry. Summary of the Invention

[0006] The technical problem to be solved by the embodiments of the present invention is to provide a method for opening a packaging barrel that protrudes from the top surface and is eccentrically arranged, without the need for image recognition, thereby solving the problem that existing opening methods heavily rely on image recognition.

[0007] A method for opening a packaging drum includes:

[0008] The first step is to obtain the packaging barrel from the barrel rotating station, and the packaging barrel has not been identified by the image recognition device before it reaches the barrel rotating station;

[0009] The second step involves using a rotating drum mechanism to clamp the packaging drum and center it.

[0010] The third step is to drive the barrel opening positioning mechanism downward by the inclined drive cylinder, so that the flipping part of the barrel opening positioning mechanism is close to the top surface of the packaging barrel and located in a circle with the center of the packaging barrel as the center and the distance from the center of the barrel opening to the center of the packaging barrel as the radius.

[0011] The fourth step involves the rotating drum mechanism driving the packaging drum to rotate. When the opening of the packaging drum collides with the positioning block, the opening of the packaging drum is limited by the positioning block. At the same time, the detection switch is triggered to send a stop signal to the drive motor of the rotating drum mechanism, and the drive motor stops.

[0012] Step 5: The barrel opening positioning mechanism retracts, while the lid opening mechanism moves towards the barrel opening and opens the lid.

[0013] The first step is that the packaging drums are conveyed to the drum rotation station by the conveyor rollers:

[0014] Each drum rotating station has an independently controlled conveyor roller; multiple drum rotating stations are arranged linearly, and a photoelectric sensor is installed in the drum rotating area of ​​each station.

[0015] First, activate the photoelectric sensor at the Nth rotating drum station, while keeping the photoelectric sensors at the previous rotating drum stations in the off state;

[0016] Once the packaging drum is conveyed along the conveyor rollers into the Nth drum rotating station, the photoelectric sensor at the rotating station detects the packaging drum and controls the conveyor rollers at the Nth drum rotating station to stop.

[0017] Then activate the photoelectric sensor at the (N-1)th drum rotating station, while keeping the photoelectric sensors at the previous drum rotating stations in the off state;

[0018] The packaging drum is conveyed along the conveyor rollers into the (N-1)th drum rotating station. After the photoelectric sensor at the rotating station detects the packaging drum, it controls the conveyor rollers at the (N-1)th drum rotating station to stop.

[0019] This process continues until the first drum-turning station also receives a packaging drum, at which point all drum-turning stations will have packaging drums.

[0020] The rotating drum station is set within the moving frame, which is a rectangular hollow structure. Each rotating drum station is equipped with a drum opening positioning mechanism driven by an inclined drive cylinder and a lid opening mechanism located above the rotating drum station.

[0021] The drum rotating mechanism includes two sets of support rollers and one drive roller; the drive roller is installed on one side of the moving frame and is driven by a drive motor, and the two sets of support rollers are arranged symmetrically on the left and right and are driven simultaneously by horizontally driven cylinders.

[0022] The second step involves the rotating drum mechanism clamping the packaging drum, including:

[0023] Two sets of support rollers are driven by a horizontally driven cylinder to move towards the drive roller. After contacting the packaging drum, the drum is positioned between the two sets of support rollers. The two sets of support rollers continue to push the drum until it contacts the drive roller, thus completing the centering of the packaging drum.

[0024] The barrel positioning mechanism includes a horizontal fixing component, a flipping component, and a detection switch. The fixing component is arranged horizontally, and the flipping component is rotatably connected to the front end of the fixing component. The end of the flipping component is located at the lowest point. After the flipping component flips, it triggers the detection switch, thereby sending a stop signal to the drive motor of the barrel rotating mechanism by the detection head.

[0025] The detection switch is a proximity switch.

[0026] The flipping component includes a horizontal part and an inclined part, with a shaft hole in the middle between the inclined part and the horizontal part for rotatable connection with the fixing component.

[0027] The fixing component is provided with a support block to keep the horizontal part of the flipping component horizontal, and a limit block to restrict the flipping of the horizontal part.

[0028] This invention provides a method for opening a packaging barrel, which does not require image recognition but can achieve the positioning of the barrel opening using only traditional mechanical devices, thereby facilitating the opening mechanism to open the barrel opening.

[0041] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Example

[0043] like Figure 1-5 As shown, the present invention provides a method for opening a packaging barrel, comprising:

[0044] The first step is to obtain the packaging barrel 10 from the barrel rotating station, and the packaging barrel 10 has not been identified by the image recognition device before it reaches the barrel rotating station;

[0045] The second step is to use a rotating drum mechanism to clamp the packaging drum and center it. In this step, the packaging drum can be automatically positioned between two sets of support rollers 31 by actively driving the support roller 32, thus achieving automatic centering after being clamped by the active roller 31. Alternatively, the moving frame 50 can be driven simultaneously while driving the support roller 32, and the moving frame 50 can drive the active roller 31 and the support roller 32 to move towards each other.

[0046] The third step involves using an inclined drive cylinder to drive the barrel opening positioning mechanism downwards, causing the flipping part of the barrel opening positioning mechanism to be close to the top surface of the packaging barrel and located in a circle with the center of the packaging barrel as the center and the distance from the center of the barrel opening to the center of the packaging barrel as the radius. By using an inclined drive cylinder, the space above the packaging barrel can be left to the lid opening mechanism without occupying the space above the packaging barrel.

[0047] Step 4: The rotating drum mechanism drives the packaging drum to rotate. When the opening of the packaging drum collides with the positioning block, the opening of the packaging drum is limited by the positioning block. At the same time, the detection switch is triggered to send a stop signal to the drive motor of the rotating drum mechanism, and the drive motor stops. This step involves ensuring that the opening of the drum collides with the flipping component during the rotation of the packaging drum.

[0048] Step 5: The barrel opening positioning mechanism retracts, while the lid opening mechanism moves towards the barrel opening and opens the lid.

[0049] The first step is that the packaging drums are conveyed to the drum rotation station by the conveyor rollers:

[0050] Each drum rotating station has an independently controlled conveyor roller; multiple drum rotating stations are arranged linearly, and a photoelectric sensor is installed in the drum rotating area of ​​each station.

[0051] First, activate the photoelectric sensor at the Nth rotating drum station, while keeping the photoelectric sensors at the previous rotating drum stations in the off state;

[0052] Once the packaging drum is conveyed along the conveyor rollers into the Nth drum rotating station, the photoelectric sensor at the rotating station detects the packaging drum and controls the conveyor rollers at the Nth drum rotating station to stop.

[0053] Then activate the photoelectric sensor at the (N-1)th drum rotating station, while keeping the photoelectric sensors at the previous drum rotating stations in the off state;

[0054] The packaging drum is conveyed along the conveyor rollers into the (N-1)th drum rotating station. After the photoelectric sensor at the rotating station detects the packaging drum, it controls the conveyor rollers at the (N-1)th drum rotating station to stop.

[0055] This process continues until the first drum-turning station also receives a packaging drum, at which point all drum-turning stations will have packaging drums.

[0056] In this step, each drum rotating station is equipped with an independent conveyor roller and photoelectric sensor, while the conveyor roller between two adjacent drum rotating stations is continuous, so that each drum rotating station can obtain a packaging drum, thereby realizing multi-station packaging drum simultaneous positioning, opening, filling and other operations.

[0057] The rotating drum station is set within the movable frame 50, which is a rectangular hollow structure. Each rotating drum station is equipped with a drum opening positioning mechanism 20 driven by an inclined drive cylinder and a lid opening mechanism 40 located above the rotating drum station.

[0058] The drum rotating mechanism 30 includes two sets of support rollers 32 and one drive roller 31; the drive roller 31 is installed on one side of the moving frame and is driven by a drive motor. The two sets of support rollers are arranged symmetrically on the left and right and are driven simultaneously by a horizontally driven cylinder.

[0059] The second step involves the rotating drum mechanism clamping the packaging drum, including:

[0060] Two sets of support rollers are driven by a horizontally driven cylinder to move towards the drive roller. After contacting the packaging drum, the drum is positioned between the two sets of support rollers. The two sets of support rollers continue to push the drum until it contacts the drive roller, thus completing the centering of the packaging drum.

[0061] The barrel positioning mechanism 20 includes a horizontal fixing member 21, a flipping member 22, and a detection switch 23. The fixing member is arranged horizontally, the flipping member is rotatably connected to the front end of the fixing member, and the end of the flipping member is located at the lowest point. After the flipping member flips, it triggers the detection switch, thereby sending a stop signal to the drive motor of the barrel rotating mechanism by the detection head.

[0062] The detection switch is a proximity switch.

[0063] The flipping component 22 includes a horizontal portion 22a and an inclined portion 22b, with a shaft hole provided between the inclined portion and the horizontal portion for rotatable connection with the fixing component.

[0064] The fixing member is provided with a support block 21b to keep the horizontal part of the flipping member horizontal, and a limit block 21a to restrict the flipping of the horizontal part.

[0065] This invention provides a method for opening a packaging barrel, which does not require image recognition but can achieve the positioning of the barrel opening using only traditional mechanical devices, thereby facilitating the opening mechanism to open the barrel opening.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
