Description

Technical Field

[0001] The present invention relates to a chain conveyor with improved structure, and more specifically, to a chain conveyor with improved durability through structural improvements. Background Technology

[0002] With the development of modern technology, the metal materials used are also constantly improving. In the past, ordinary steel was mostly used, but in recent years, in order to improve the durability of mechanical parts such as automobiles, carbon steel containing carbon or various special steels with higher strength have been gradually adopted.

[0003] To handle this high-strength material, the peripheral equipment required for product manufacturing, such as processing or conveying, needs to be gradually improved, which leads to a significant increase in the cost of modifying or manufacturing the peripheral equipment.

[0004] For the same reasons mentioned above, conveyors mainly used for transporting materials or products are also not immune to this problem. In the case of chain conveyors, there is a problem that high-strength conveyed materials can get stuck in the gaps between the chains, causing damage to the conveyor itself.

[0005] In particular, waste, debris, aggregate, or irregularly shaped small chips from high-strength materials can get stuck in the narrow gaps between conveyor hinges. As the conveyor operates, these chips will gradually wear down, widen the gaps, and eventually cause damage. Summary of the Invention

[0006] (The problem that the invention aims to solve)

[0007] This invention is proposed to solve the aforementioned problems. The purpose of this invention is to provide a chain conveyor that can prevent the conveyed material from getting stuck by changing the structure of each component.

[0008] Furthermore, the object of the present invention is to provide a chain conveyor with a structure that can prevent jamming and minimize interference between components.

[0009] (The measures taken to solve the problem)

[0010] To address the aforementioned technical problem, the present invention provides a conveyor composed of multiple interconnected frames. Each frame includes: a plate-shaped base; pin holes formed on both sides of the base along the direction of connection with adjacent frames for pin engagement; and pin hole covers extending from the base, closely abutting and covering the outer peripheral surfaces of the pin holes of adjacent frames. The pin holes are formed at predetermined intervals along their length, each including a hollow insertion port forming a closed curved surface, coaxially engaging with the pin holes of adjacent frames and contacting the end of the insertion port. Multiple pin holes are alternately engaged in a zigzag pattern and share a single pin. The pin hole covers are located on adjacent frames. The pin hole cover slides close to the outer peripheral surface of the pin hole, forming a predetermined distance with other adjacent frames. The pin hole cover extends to cover more than half of the upwardly exposed portion of the pin hole, and is formed to have the same distance from the pin hole and the same length as the pin hole. The end of the inner peripheral surface of the pin hole cover contacts the end of the outer peripheral surface of the pin hole. The frame forms the pin hole cover on the side opposite to the side where the pin hole is formed, with the direction of travel of the conveyor as a reference. All frames forming the conveyor have the same shape. The base extends along the length direction with the same cross section and may also include a reinforcing part that is reinforced in a way that makes the center protrude to a predetermined degree.

[0011] (The effect of the invention)

[0012] The conveyor of the present invention, through structural improvements, can prevent the conveyed material from getting stuck, thereby reducing wear caused by the conveyed material, extending the service life of the conveyor, and relatively reducing the cost required to select conveyor materials according to the strength of the conveyed material.

[0013] Furthermore, the conveyor of the present invention can be implemented by modifying an existing conveyor, thus saving the cost required to improve the device according to the material being conveyed. Attached Figure Description

[0020] This invention provides a conveyor composed of multiple interconnected frames. Each frame includes: a plate-shaped base; pin holes formed at both ends of the base along the direction of connection with adjacent frames for pin engagement; and pin hole covers extending from the base, closely abutting and covering the outer peripheral surfaces of the pin holes of adjacent frames. The pin holes are formed at predetermined intervals along their length, each including a hollow insertion port forming a closed curved surface, coaxially engaging with the pin holes of adjacent frames and contacting the end of the insertion port. Multiple pin holes are alternately engaged in a zigzag pattern and share a single pin. The pin hole covers are located outside the pin holes of adjacent frames. The frame slides close to the periphery and forms a predetermined distance with other adjacent frames. The pin hole cover extends to cover more than half of the exposed portion of the pin hole, and is formed to have the same distance from the pin hole and the same length as the pin hole. The end of the inner periphery of the pin hole cover contacts the end of the outer periphery of the pin hole. The frame forms the pin hole cover on the side opposite to the side where the pin hole is formed, with the direction of travel of the conveyor as a reference.

[0024] Furthermore, the side wing may include a first clamp and a second clamp that extend from each other and form a height difference, wherein the first clamp and the second clamp each include a clamp hole coaxial with the pin hole at their lower ends.

[0025] Furthermore, the side wing may include an inclined portion that connects the first clamp and the second clamp at a predetermined angle.

[0026] Furthermore, the lower end of the side wing can contact the inclined portion of the adjacent other side wing in the direction of engagement with the frame.

[0027] Furthermore, the upper end of the side portion of the wing can protrude laterally and is adjacent to the inclined portion of other adjacent wing in the opposite direction of its connection with the frame.

[0028] Furthermore, the upper surface of the side wing can gradually decrease in height in both directions.

[0029] Furthermore, the side wing may also include a placement portion that protrudes from the lower part for placing the frame.

[0032] Furthermore, the present invention may also include a discharge hole formed on one side of the protrusion and extending to the other side of the protrusion on which the base is formed.

[0033] Furthermore, the base may also include drainage holes, which are distributed throughout the base and extend from top to bottom.

[0034] Methods for implementing the invention

[0035] The technical concept of the present invention will now be described in detail with reference to the accompanying drawings. As stated above, the terms or words used in this specification and the scope of the invention should not be limited to their ordinary or dictionary meanings, but should be interpreted as meanings and concepts consistent with the technical concept, based on the principle that the inventor can appropriately define the terminology and concepts in order to best illustrate their own invention. Therefore, the embodiments described in this invention and the structures shown in the accompanying drawings are only the most preferred embodiments of the present invention and do not fully represent the technical concept of the present invention. Therefore, it should be understood that there are many variations that can replace them at the time of the submission of this invention.

[0036] Figure 1 This is a partial perspective view of the conveyor 10 of the present invention. As shown, the conveyor 10 may generally include a frame 100, side wings 200, and a chain.

[0037] More specifically, the conveyor 10 may include a structure consisting of multiple identical frames 100, side wings 200, and chains 300 connected together. The frames 100 may be plate-like structures, including structures capable of connecting with adjacent frames 100.

[0038] Furthermore, the side wings 200, used to prevent the conveyed material being transported on the conveyor 10 from falling to the side or from getting stuck in structures located on the side of the conveyor 10, can be integrated into a side perpendicular to the connection direction of the multiple connected frames 100. In this case, as shown in the figure, the multiple side wings 200 can extend into an overlapping form.

[0039] Furthermore, the chain 300 is a structure that is combined with a drive device to enable the conveyor 10 to rotate, and can be combined and extended on the other side of the side wing 200 that is combined with the frame 100.

[0040] Figure 2 An exploded view of the frame 100 of the conveyor 10 of the present invention is shown. As shown, the frame 100 may include a base 110, a pin hole 120, and a pin hole cover 130.

[0041] More specifically, the frame 100 may include a flat base 110. The base 110 provides space for placing transported items.

[0042] Furthermore, the pin holes 120 are hollow structures designed for pin engagement and can be formed on both sides of the base 110 along the direction in which the frame 100 connects to other adjacent frames 100. In this case, the pin holes 120 can be formed at predetermined intervals along the length direction, preferably spaced apart in a manner consistent with the central axis, so that a pin can engage with the spaced-apart pin holes 120.

[0043] Furthermore, the pin hole cover 130 may extend and be formed on the base 110. The pin hole cover 130 may be formed in the same direction as the pin hole 120. The pin hole cover 130 can closely abut and cover the outer peripheral surface of the pin hole 120 of adjacent other frames 100. That is, when the plurality of frames 100 are interconnected, the pin hole cover 130 can cover the gap formed between the pin holes 120 joined in a zigzag shape and the base 110. For this purpose, as shown in the figure, preferably, the pin hole cover 130 is formed to a length greater than the distance between the pin holes 120.

[0044] Figure 3 This is a cross-sectional view of the conveyor 10 of the present invention. As described above, the frame 100 can be connected and joined by the pin holes 120 formed at a predetermined interval along the length direction and the pin holes 120 of the adjacent frame 100 engaging in a zigzag pattern, so that the insertion port 121 is aligned, and by means of a pin connecting to the insertion port 121.

[0045] In this case, preferably, the pin hole 120 and the insertion port 121 are formed in a circular shape, so that the angle can be flexibly changed when the conveyor 10 rotates as a whole.

[0046] In this case, to prevent the pin hole cover 130 from interfering with other adjacent frames 100 when the conveyor 10 rotates, as shown in the figure, preferably, a predetermined spacing A is formed. That is, the pin hole cover 130 is an arc shape that can fit tightly against the outer peripheral surface of the pin hole 120, and can slide on the outer peripheral surface of the pin hole 120 as the conveyor 10 rotates. To prevent mutual interference during this operation, it can be designed to form the spacing A shown in the figure.

[0047] Figure 4 An exploded view of the side wing 200 of the conveyor 10 of the present invention is shown. As shown, the side wing 200 may be formed in the form of a first clamp 210 and a second clamp 220 extending with a height difference D.

[0048] More specifically, the side wing 200 can form a height difference D by bending the flat plate into a stepped shape. That is, the side wing 200 can extend from the first clamp 210 to the second clamp 220 to overlap with other adjacent side wings 200, thereby forming a height difference D corresponding to the thickness of the first clamp 210 and the second clamp 220.

[0049] In this case, as an example, the side wing 200 may have clamp holes 211 and 221 formed at the lower ends of the first clamp 210 and the second clamp 220, respectively. Preferably, the clamp holes 211 and 221 are coaxially connected with the insertion port 121 of the pin hole 120. That is, as described above, it can be connected to the side of the frame 100 and connected together with the pin.

[0050] Furthermore, the side wing 200 may have an inclined portion 201 formed at the position where the first clamp 210 and the second clamp 220 are connected. The inclined portion 201 may extend along the length direction of the side wing 200 and form a predetermined angle with the upper and lower surfaces of the side wing 200. This is to prevent mutual interference and minimize the gap between the side wings 200 adjacent to the side wing 200 as they rotate around the clamp holes 211 and 221 with the conveyor 10.

[0051] Furthermore, the side wing 200 may also include a placement portion 230, which protrudes from the lower part in the direction of engagement with the frame 100. The placement portion 230 is the location for placing the frame 100, preferably engaging with the lower surface of the frame 100. That is, the placement portion 230 serves to strengthen the gap between the frame 100 and the side wing 200 and to distribute the load acting on the pin, thus providing a structure that makes the conveyor 10 more robust.

[0052] In this case, as a variation, the placement portion 230 can be directly coupled to the frame 100. That is, as described above, in addition to being coupled by the pin, the side wing 200 can also be coupled to the side of the frame 100 by directly fastening the placement portion 230 to the frame 100. In this variation, embodiments without the clamp holes 211, 221 can also be included.

[0053] Figure 5 This diagram illustrates the connection state of the side wings 200 of the conveyor 10 of the present invention. As shown, the side wings 200 can be coupled to other adjacent side wings 200 by sharing the pin through clamp holes 211 and 221. That is, the pin coupled to the pin hole 120 can be coupled by passing through the clamp hole 211 of the first clamp 210 of the corresponding side wing 200 and the clamp hole 221 of the second clamp 220 of the adjacent side wing 200 together.

[0054] In this case, preferably, the clamp holes 211 and 221 are formed in a circular shape, so that they can rotate about the pin. That is, the side wings 200 can rotate about the clamp holes 211 and 221 relative to other adjacent side wings 200.

[0055] In this case, as described above, when the side wing 200 is overlapped and connected with other adjacent side wings 200 in a manner with a height difference, they may interfere with each other. In order to prevent this, an inclined portion 201 that forms a predetermined angle with the upper and lower surfaces of the side wing 200 may also be included.

[0056] In this configuration, the upper side portion 202 of the side wing 200 can protrude laterally to minimize the gap with the inclined portion 201. Furthermore, the upper surface 202-1 of the side wing 200 gradually decreases in height towards both sides, thereby maintaining a minimum gap with the inclined portions 201 of adjacent side wings 200 and preventing mutual interference when the side wing 200 rotates around the clamp holes 211, 221.

[0057] In this case, preferably, the upper side 202 of the side wing 200 is adjacent to the inclined portion 201 in the opposite direction to its engagement with the frame 100. This is to prevent the conveyor from getting stuck in the gap.

[0058] The lower side end 203 of the side wing 200 may be designed to contact the inclined portion 201. The lower side end 203 serves as a structure to prevent gaps from forming on the inner side in the direction of engagement with the frame 100 for the same reasons described above. Preferably, the lower side end 203 is formed in a curved shape so that the inclined portions 201 of adjacent side wings 200 can contact and slide when the side wing 200 rotates relative to the clamp hole.

[0059] Figure 6 The frame 100 of another embodiment of the present invention is shown. As shown, the frame 100 may include at least one of the following on the base 110: a reinforcing part 111, a protrusion 112, a discharge hole 113, and a protruding hole 114 in which the protrusion and the discharge hole are combined.

[0060] Reference Figure 6 In part (a), the base 110 may further include a reinforcing portion 111. The reinforcing portion 111 is used to reinforce the overall twisting or bending of the base 110 to resist the force exerted by the transported object during falling or transporting, as shown in the figure, and may extend along the length direction of the base 110, thereby thickening the center of the base 110.

[0061] Furthermore, the base 110 may form a plurality of protrusions 112. The protrusions 112 may be distributed integrally on the upper surface of the base 110 in contact with the conveyed material and formed in the form of pits. The protrusions 112 are used to prevent chips generated during the cutting process or the conveyed material from adhering to the upper surface of the flat base 110 due to cutting oil or the like.

[0062] Reference Figure 6 In part (b), the base 110 may form a plurality of discharge holes 113. The discharge holes 113 are used to discharge excess liquid that falls along with the conveying material such as cutting oil, and preferably are formed in a form that extends through the base 110 and discharges liquid downward.

[0063] Reference Figure 6 In part (c), the base 110 may include the protrusion and protruding holes 114, 114-1 in the form of drainage holes. The protruding holes 114, 114-1 may protrude upwards on the base 110 and also include holes extending downwards through the protrusion for liquid drainage. As an example, as shown in the figure, the protruding holes 114, 114-1 may be formed as hemispherical protrusions extending downwards from the side.
