Description

Technical Field

[0001] This utility model relates to the field of filling machines, and in particular to a barrel opening detection and positioning mechanism for packaging barrels. Background Technology

[0002] With the advancement of intelligent technology, intelligent identification technology is being increasingly applied in industry. Taking the filling machine industry as an example, in order to achieve accurate automatic filling, barrel opening recognition has become a commonly used technology by many manufacturers.

[0003] Even so, intelligent recognition cannot be applied to all application scenarios. At least for some work scenarios, intelligent recognition is not the optimal solution. This is because intelligent recognition inevitably requires image capture and the judgment of information features within the image, both of which heavily rely on lighting. In environments with fluctuating lighting or constantly changing lighting conditions, intelligent recognition cannot function effectively. Furthermore, intelligent recognition requires unobstructed access. For example, when recognizing the opening of a packaging barrel, not only must the opening not be obstructed, but the overall outline of the packaging barrel must also remain unobstructed; otherwise, it will cause problems for intelligent recognition. Achieving this would inevitably affect the design and layout of other structural components (the light domain of the recognition device must not be affected).

[0004] The problem with intelligent recognition also includes its high cost of use. For many businesses and individuals with limited financial resources, intelligent recognition exceeds their budget. Utility Model Content

[0005] The technical problem to be solved by this utility model embodiment is to provide a packaging barrel opening detection and positioning mechanism that uses conventional detection methods to identify and position the opening of the packaging barrel during rotation, thereby overcoming various limitations of intelligent identification.

[0006] A barrel opening detection and positioning mechanism includes a horizontal fixing component, a rotating component, a fixing plate, and a detection head. The rotating component includes a horizontal rod and a front contact, which are connected to form an L-shape, extending downwards and below the horizontal rod. The rotating component is connected to the side of the horizontal fixing component via a rotating shaft, which is connected to the front end of the horizontal fixing component and the connection point between the horizontal rod and the front contact of the rotating component. The horizontal fixing component has a lower limit position supporting the horizontal rod and keeping it horizontal, and an upper limit position above the horizontal rod and maintaining a distance from it, so that the horizontal rod is blocked by the upper limit position after being rotated upwards at a certain angle. The front contact is mounted on the fixing plate, which is connected to the horizontal fixing component. The detection head is located within the area where the horizontal rod of the rotating component rotates upwards: when the horizontal rod is horizontal, it separates from the detection head; when the horizontal rod rotates upwards, it triggers the detection head.

[0007] The detection head is a proximity switch; or, the detection head is a photoelectric sensor switch; or, the detection head is a touch switch; or, the detection head is a magnetic sensor switch, and correspondingly, the horizontal rod is provided with a magnetic device.

[0008] The lower limit is an arc-shaped supporting structure, and the upper limit is a limiting post integrally formed with the horizontal fixing component.

[0009] The flip angle of the horizontal bar formed by the lower limit and the upper limit does not exceed 30 degrees.

[0010] The center of gravity of the rotating component is located at the horizontal rod.

[0011] The lower surface of the horizontal rod is aligned with the lower surface of the horizontal fixing member, and the height of the lower end of the front contact is lower than the height of the lower surface of the horizontal fixing member.

[0012] It also includes a rear seat plate for connection to the upper rear of the horizontal fastener.

[0013] It also includes a drive cylinder, which is obliquely connected to the rear seat plate to generate a downward and forward driving force on the rear seat plate.

[0014] This utility model provides a barrel opening detection and positioning mechanism. The front contact head detects the position of the barrel opening and is touched by the barrel opening, causing the front contact head to drive the horizontal rod to rotate around the rotating axis. The upward flipping action of the horizontal rod triggers the detection head, thereby determining that the barrel opening is in place. The upper limit position restricts the flipping of the horizontal rod, thereby positioning the barrel opening. Attached Figure Description

[0029] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model 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 full understanding of this utility model. However, this utility model can be implemented 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 this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0030] Example

[0031] like Figure 1-7As shown, this utility model provides a barrel opening detection and positioning mechanism for packaging barrels, including a horizontal fixing member 10, a rotating member 20, a fixing plate 30, and a detection head 40. The rotating member 20 includes a horizontal rod portion 22 and a front contact 21. The front contact 21 and the horizontal rod portion 22 are connected to form an L-shape, so that the front contact 21 extends downward and is lower than the horizontal rod portion 22. The rotating member 20 is connected to the side of the horizontal fixing member 10 through a rotating shaft 13. The rotating shaft 13 is connected to the front end of the horizontal fixing member 10 and the connection point between the horizontal rod portion 22 and the front contact 21 of the rotating member 20. The horizontal fixing member 10 is provided with a lower limit that supports the horizontal rod portion 22 below it and keeps the horizontal rod portion 22 horizontal. Position 11 and upper limit position 12 above and at a distance from the horizontal rod 22, so that after the horizontal rod 22 is flipped upward at a certain angle, it is blocked by the upper limit position 12, and the position of the front contact 21 will be fixed, thus forming a positioning relationship between the front contact 21 and the opening of the packaging barrel; the front contact 21 is mounted on the fixing plate 30, and the fixing plate 30 is connected to the horizontal fixing member 10, so that the detection head 40 is in the area where the horizontal rod 22 of the rotating member 20 is flipped upward: when the horizontal rod 22 is in a horizontal state, the horizontal rod 22 is separated from the detection head 40; when the horizontal rod 22 is flipped upward, the detection head 40 is triggered. When the current contact 21 is in the non-triggered state, the horizontal rod 22 and the detection head 40 are separated, and the detection head is not triggered. When the current contact 21 comes into contact with the opening of the packaging drum and is triggered by the opening of the packaging drum to flip backward, the horizontal rod 22 flips upward. At this time, the horizontal rod 22 will approach or contact the detection head 40, thereby triggering the detection head 40 to emit an electrical signal. On the filling machine, the electrical signal from the detection head 40 is used to control the drum rotating mechanism to stop rotating, thereby positioning the opening of the packaging drum at the position of the front contact 21.

[0032] The horizontal fixing part 10 and the rotating part 20 are integrally formed parts, and the fixing plate 30 is a flat plate structure.

[0033] The detection head 40 can be designed in various ways, such as: the detection head 40 is a proximity switch; or, the detection head 40 is a photoelectric sensor switch; or, the detection head 40 is a touch switch; or, the detection head 40 is a magnetic sensor switch, and correspondingly, the horizontal rod 22 is provided with a magnetic device.

[0034] The lower limit 11 is an arc-shaped supporting structure, and the upper limit 12 is a limiting post integrally formed with the horizontal fixing member 10. The shape of the lower limit 11 can be designed to match the edge shape of the horizontal rod 22, or it can be designed as a limiting post, limiting block, or other structural designs.

[0035] The flipping angle of the horizontal rod portion 22 formed by the lower limit position 11 and the upper limit position 12 does not exceed 30 degrees.

[0036] The center of gravity of the rotating component 20 is located at the horizontal rod portion 22.

[0037] The lower surface of the horizontal rod 22 is aligned with the lower surface of the horizontal fixing member 10, and the height of the lower end of the front contact 21 is lower than the height of the lower surface of the horizontal fixing member 10. This makes the lower end of the front contact 21 the lowest position in the entire packaging barrel opening detection and positioning mechanism, and the packaging barrel opening is detected from this position.

[0038] This utility model provides a barrel opening detection and positioning mechanism for packaging barrels, and also includes a rear seat plate 50 for connecting to the upper rear part of the horizontal fixing member 10.

[0039] This utility model provides a packaging barrel opening detection and positioning mechanism, which also includes a drive cylinder 60. The drive cylinder 60 is obliquely connected to the rear seat plate 50 to generate a downward and forward driving force on the rear seat plate. Since the force is simultaneously downward and forward, the control path can be simplified, and a single drive cylinder can achieve movement control in two coordinate directions. Of course, when designing the driving direction of the drive cylinder, the position where this direction intersects with the surface of the packaging barrel needs to be calculated in advance; this position should be exactly the positioning point of the packaging barrel opening.

[0040] This utility model provides a barrel opening detection and positioning mechanism. The front contact 21 detects the position of the barrel opening. When the barrel opening touches the front contact 21, it causes the horizontal rod 22 to rotate around the rotating shaft 13. The upward flipping action of the horizontal rod 22 triggers the detection head 40, thereby determining that the barrel opening is in place. The upper limit 12 restricts the flipping of the horizontal rod 22, thereby positioning the barrel opening.

[0041] 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.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
