Description

Technical Field

[0001] This invention relates to the field of automatic online sampling technology for continuous tubular materials in straight seam welded pipe production lines, specifically to a concealed online material sampling flap that does not occupy the production line cycle time. Background Technology

[0002] With the diversification of social development, various sub-sectors of products have emerged in today's high-frequency welded pipe production lines. Some of these products have relatively stricter quality requirements, necessitating sampling and testing before leaving the factory. In practice, sampling and testing of high-frequency welded pipe production lines is typically conducted on the stacking roller conveyor before the finished pipes are bundled. However, given the current immaturity of automated sampling technology for finished pipes, manual sampling is usually performed online at high speed, or, for safety reasons, sampling is done by stopping the machine. Neither of these methods is optimal. If random sampling of finished pipes could be performed online without stopping the production line, the danger to workers would be greatly reduced. Therefore, the development of a hidden online sampling flap that enables random sampling on the production line without stopping has become a new trend. Summary of the Invention

[0003] This embodiment provides a concealed online material-picking flip-plate that enables random sampling on a production line without stopping the machine. It involves installing a discharge slide plate at a pre-stacking station and then mounting a flip-up material-picking flip-plate on the discharge slide plate. Online sampling is achieved through the flipping action of the flip-up flip-plate. This technical solution features a simple structure, ease of maintenance and repair, wide applicability, cost savings, and improved accuracy and efficiency.

[0004] Specifically, on one hand, a concealed online material handling flap is used to achieve sampling without stopping the machine during continuous online operation. It is equipped with a discharge slide plate p, and the upper part of the discharge slide plate p is equipped with a stacking plane mp. The bar stock b enters the stacking plane mp of the discharge slide plate p one by one and is neatly arranged in a row on the stacking plane mp. The discharge slide plate p is also equipped with a material handling flap q. The material handling flap q is hinged to the discharge slide plate p through a hinge shaft j, so that it can rotate relative to the discharge slide plate p. The material handling flap q is also equipped with a material handling groove qy. By the rotation of the material handling flap q relative to the discharge slide plate p, the bar stock b can fall into the material handling groove qy under the action of gravity, so that the bar stock b can leave the discharge slide plate p and enter the sampling process.

[0005] According to one aspect of a specific embodiment of the present invention, the material picking flap q is further provided with a flap plane qf that is in the same plane as the stacking plane mp provided on the discharge slide plate p, and the discharge slide plate p is further provided with a material picking opening k. The material picking flap q can rotate to drive the flap plane qf to rotate and just fill the material picking opening k.

[0006] According to one aspect of a specific embodiment of the present invention, the material picking trough qy is C-shaped and disposed below the flip plate plane qf. A receiving part c is also provided at the end of the material picking trough qy away from the flip plate plane qf. The receiving part c is in the shape of a flat plate and can overlap with the material picking opening k under the rotation of the material picking flip plate q to form a closed path.

[0007] According to one aspect of a specific embodiment of the present invention, the material taking flip plate q is further provided with a guide surface d on the side of the material taking groove qy located in the C-shape near the flip plate plane qf. The guide surface d is set to be arc-shaped and arranged opposite to the flip plate plane qf. Attached Figure Description

[0015] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0016] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present invention by way of example, but should not be used to limit the scope of the present invention. That is, the present invention is not limited to the described preferred embodiments, and the scope of the present invention is defined by the claims.

[0017] In the description of the embodiments of the present invention, it should be noted that, unless otherwise stated, "perpendicular" and "parallel" are not only absolute in a mathematical sense, but can be understood as "approximately perpendicular" and "approximately parallel".

[0018] Figure 1 This is a schematic diagram of the basic structure of the overall layout of an embodiment of the present invention.

[0019] like Figure 1 As shown, this embodiment provides a hidden online material-picking flipper that enables random sampling on a production line without stopping the machine. It involves setting a discharge slide plate at a pre-stacking station and mounting a flipper on the discharge slide plate. Online sampling is achieved through the flipping action of the flipper. This technical solution has a simple structure, is easy to maintain and repair, has a wide range of applications, saves costs, and improves accuracy and efficiency. In this embodiment, the specific structure may include a plate-shaped discharge slide plate p for neatly stacking bar stock b. The discharge slide plate p can be horizontal or inclined; in this embodiment, it is preferably inclined. The upper outer surface of the discharge slide plate p also has a flat stacking plane mp. The bar stock b enters the stacking plane mp on the upper surface of the discharge slide plate p one by one from the previous station and is neatly arranged in a row on the stacking plane mp. In this embodiment, the discharge slide plate p on the side where the bar stock b enters the stacking plane mp is at a higher position, and the other side is at a lower position, so the bar stock b can slide to the other side under the action of gravity after entering the stacking plane mp. A material-retrieving flap q is also provided in the middle of the discharge slide plate p. The material-retrieving flap q is hinged to the lower part of the discharge slide plate p via a hinge shaft j, enabling it to rotate relative to the discharge slide plate p. The material-retrieving flap q is also provided with a material-retrieving groove qy. By rotating the material-retrieving flap q relative to the discharge slide plate p, the bar stock b can fall into the material-retrieving groove qy under the action of gravity, thus detaching the bar stock b from the discharge slide plate p and entering the sampling process.

[0020] Figure 2 This is a schematic diagram of the material handling flap structure q in an embodiment of the present invention.

[0021] like Figure 2As shown, in one aspect of a specific embodiment of the present invention, the material-retrieving flap q is configured as a hook-shaped structure, and a hinge hole is provided at one end away from the opening direction of the hook. The hinge shaft j is disposed at the lower end of the discharge slide plate p. The material-retrieving flap q is hinged to the hinge shaft j through the hinge hole. The rotational connection between the hinge hole and the hinge shaft j enables the material-retrieving flap q to rotate relative to the discharge slide plate p. The rotational movement of the discharge slide plate p can be achieved by driving a hydraulic cylinder or by driving a gear with an electric motor. Since the implementation of its rotational movement is prior art, further technical solutions will not be described here.

[0022] Furthermore, preferably, the material picking groove qy is located inside the hook-shaped bend of the material picking flap q, and in shape, the material picking groove qy is shaped like the letter C. On one side of the material picking flap q, there is also a flap plane qf that is coplanar with the stacking plane mp on the discharge slide p. The flap plane qf can swing under the rotation of the material picking flap q, that is, the angular change of the flap plane qf in space. It should be explained that the fact that the flap plane qf and the stacking plane mp on the discharge slide p are coplanar refers to the state that can be achieved when the material picking flap q rotates to a designated position.

[0023] Preferably, the material chute qy is C-shaped and positioned below the flip plate plane qf. A receiving portion c is provided at the end of the C-shaped material chute qy away from the flip plate plane qf. This receiving portion c is flat and extends outwards, and it can swing under the rotation of the material chute flip plate q. Furthermore, a guide surface d is provided on the side of the C-shaped material chute qy closest to the flip plate plane qf. This guide surface d is arc-shaped and arranged opposite to the flip plate plane qf.

[0024] Figure 3 This is a schematic diagram of the material discharge slide plate p structure according to an embodiment of the present invention.

[0025] like Figure 3 As shown, in one aspect of a specific embodiment of the present invention, the middle part of the discharge slide plate p is provided with a hollowed-out material picking opening k at the position where the material picking flap q is set. The material picking opening k can accommodate the bar material b to pass through. When the bar material b slides to the other side under the action of gravity after entering the stacking plane mp, the bar material b can fall into and pass through the material picking opening k without the intervention of the material picking flap q.

[0026] According to one aspect of a specific embodiment of the present invention, the material-retrieving flap q, constrained by the hinge shaft j, achieves rotation relative to the discharge slide plate p, ultimately having two rotational positions. The first rotational position is achieved by the rotation of the material-retrieving flap q, causing the flap plane qf mounted on it to swing to a position where it is on the same plane as the stacking plane mp mounted on the discharge slide plate p. At this position, the flap plane qf precisely fills the gap created by the material-retrieving opening k. When the material-retrieving flap q is in the first rotational position, the bar material b, after entering the stacking plane mp, can freely slide to the other side under the action of gravity without falling into the material-retrieving opening k, and can continue sliding to the next position. The second rotating station is relative to its position in the first rotating station. The material-retrieving flap q rotates clockwise along the hinge axis j. Simultaneously, the receiving part c on the material-retrieving flap q swings. As the material-retrieving flap q rotates, the receiving part c eventually swings to the lower end of the material-retrieving opening k and abuts against the lower end of the discharge slide plate p, forming a closed path by overlapping with the material-retrieving opening k. At this position, the flap plane qf swings with the rotation of the material-retrieving flap q and eventually leaves the material-retrieving opening k, making the material-retrieving opening k completely open. At this time, the guide surface d, which is set opposite to the flap plane qf, flips to the raised position. The guide surface d can block the bar stock b at this position, preventing the bar stock b from crossing the material-retrieving opening k due to excessive falling speed. At the same time, the guide surface d is set to an arc shape, which can more effectively guide the bar stock b, allowing the bar stock b to enter the material-retrieving groove qy more smoothly.

[0027] Figure 4 This is a schematic diagram of the material handling flap q flipping in an embodiment of the present invention.

[0028] Figure 5 This is a schematic diagram of the bar stock b falling into the transfer roller conveyor z according to an embodiment of the present invention.

[0029] like Figure 4 and Figure 5As shown, according to one aspect of a specific embodiment of the present invention, the specific working process is as follows: When the production line does not need to sample the bar stock b, the sampling flap q rotates to its first rotating position. The bar stock b can slide freely to the other side under the action of gravity after entering the stacking plane mp without falling into the sampling notch k, and can continue to slide to the next position. When the production line needs to sample the bar stock b, the sampling flap q rotates to its second rotating position. The bar stock b passes through the sampling notch k along the receiving part c under the action of gravity and falls into the sampling groove qy. Then the sampling flap q rotates back to its first rotating position. The remaining bar stock b that does not need to be sampled continues to slide to the next position. At this time, the bar stock b that falls into the sampling groove qy will fall onto the transfer roller conveyor z located below the discharge slide plate p when the sampling flap q rotates from its second rotating position to its first rotating position. On the transfer roller conveyor z, the sampled bar stock b will complete the sampling work.

[0030] It should be understood that the description of specific embodiments of the present invention in the specification is exemplary and should not be construed as an undue limitation on the scope of protection of the present invention. The scope of protection of the present invention is defined by its claims and covers all embodiments falling within its scope and their obvious equivalents.
