Description

Chain belt conveyor with anti-jamming structure

[0001] The present invention relates to a chain belt conveyor with an improved structure, and more specifically, to a chain belt conveyor with an improved structure to increase durability.

[0002] With the advancement of modern technology, the metal materials used have also undergone significant advancements. While conventional steel was widely used in the past, carbon-containing steel and various special steels with enhanced strength are increasingly being used to enhance the durability of mechanical components such as automobiles.

[0003] In order to handle materials with such increased strength, peripheral devices required for product production, such as processing or transport, also need to be gradually improved. Consequently, there was a problem in that the cost of modifying or manufacturing peripheral devices increased significantly.

[0004] As mentioned above, conveyors that are mainly used to transport materials or products cannot avoid this problem. In the case of chain-type conveyors, there was a problem in which strong materials to be transported got caught in the gaps of the chain, causing damage to the conveyor itself.

[0005] In particular, there was a problem that when the conveyor rotates while waste materials, scrap, aggregates, or irregularly shaped fine chips generated after processing of strong materials are caught in the narrow gap between the hinges of the conveyor, wear gradually occurs and the gap grows, leading to breakage.

[0006] The present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a chain belt conveyor capable of preventing the transported material from getting caught by changing the structure of each component.

[0007] In addition, an object of the present invention is to provide a chain belt conveyor having a structure that can prevent jamming while minimizing interference between components.

[0008] The present invention relates to a conveyor configured by connecting a plurality of frames to solve the above-described technical problem, wherein the frame comprises a plate-shaped base, pinholes formed at both ends of the base in a direction connected to an adjacent frame and to which pins are coupled, and pinhole covers formed to extend from the base and to be in close contact with and cover the outer surface of the pinholes of the adjacent frame, wherein the pinholes are formed at a constant interval in the longitudinal direction and are hollow and have insertion holes that form a closed surface, and are coaxially coupled with the pinholes of the adjacent frame, such that the ends of the insertion holes are in contact, and a plurality of pinhole covers are alternately coupled in a zigzag pattern to share a single pin, and the pinhole covers slide in close contact with and on the outer surface of the pinholes of the adjacent frame, and form a constant gap with the adjacent frame, and extend to cover more than half of the portion where the pinholes are exposed upward, and are formed to be equal to the interval between the pinholes and the length of the pinholes, such that the inner peripheral end of the pinhole covers and the outer peripheral end of the pinholes are in contact, and The frame may form the pinhole cover on the other side of the side where the pinhole is formed based on the direction of movement of the conveyor, so that all frames forming the conveyor have the same shape, and the base may further include a reinforcing portion that is extended so that the cross-section is the same in the longitudinal direction, but is reinforced so that the central portion protrudes uniformly.

[0009] The conveyor according to the present invention has the advantage of being able to prevent jamming of the transported material through structural improvement, thereby minimizing wear caused by the transported material and extending the life of the conveyor, and relatively reducing the cost of the material of the conveyor according to the strength of the transported material.

[0010] In addition, the conveyor according to the present invention can be implemented by modifying an existing conveyor, and thus has the advantage of reducing the cost of improving the device according to the material of the material to be transported.

The pinhole cover is formed on the other side of the side where the pinhole is formed, so that all frames forming the conveyor have the same shape, and the base may further include a reinforcing portion that is extended so that the cross-section is the same in the longitudinal direction, but is reinforced so that the central portion protrudes uniformly.

[0018] In addition, the pinhole cover can slide on the outer surface of the pinhole of another adjacent frame and form a certain gap with the other adjacent frame.

[0024] Additionally, the upper side of the side wing may protrude laterally and may be adjacent to the slope of another adjacent side wing in the opposite direction to which it is coupled with the frame.

[0025] Additionally, the upper surface of the side wing may have a shape in which the height gradually decreases in both directions.

[0026] Additionally, the side wing may further include a mounting portion formed to protrude from the lower portion and on which the frame is mounted.

[0027] Additionally, the base may further include a reinforcing member that extends in the longitudinal direction but is reinforced so that the central portion protrudes.

[0029] In addition, it may further include a discharge hole formed on the side of the protrusion and penetrating to the other side of the base where the protrusion is formed.

[0030] Additionally, the base may further include a discharge hole distributed throughout the entire base and extending from top to bottom.

[0031] Hereinafter, the technical idea of ​​the present invention will be described in more detail using the attached drawings. Prior to this, it should be noted that the terms and words used in this specification and claims should not be interpreted as having conventional or dictionary meanings, and should be interpreted with meanings and concepts that are consistent with the technical idea of ​​the present invention, based on the principle that the inventor can appropriately define the concept of the term to best explain his or her own invention. Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical idea of ​​the present invention. Therefore, it should be understood that various modified examples that can replace them may exist at the time of filing this application.

[0032] Fig. 1 is a perspective view showing a portion of a conveyor (10) according to the present invention. As shown, the conveyor (10) may largely include a frame (100), a side wing (200), and a chain.

[0033] To explain in more detail, the conveyor (10) may include a configuration in which a plurality of frames (100), side wings (200), and chains (300) of the same shape are connected. The frame (100) may have a configuration that can be connected to another frame (100) adjacent to the plate-shaped configuration.

[0034] In addition, the side wing (200) is intended to prevent the material being transported on the conveyor (10) from being deviated laterally or from being caught in a structure located on the side of the conveyor (10), and may be coupled to a side in a direction perpendicular to the connection direction of a plurality of connected frames (100). At this time, the side wing (200) may be configured in a form in which a plurality of pieces are overlapped and extended, as illustrated.

[0035] In addition, the chain (300) is configured to be coupled with a driving device so that the conveyor (10) can rotate, and can be extended by being coupled to the other side of the side coupled with the frame (100) from the side wing (200).

[0036] Fig. 2 is an exploded view of the frame (100) of the conveyor (10) according to the present invention. As shown, the frame (100) may include a base (110), a pinhole (120), and a pinhole cover (130).

[0037] To explain in more detail, the frame (100) may include a flat plate-shaped base (110). The base (110) may provide a space in which the transported material is settled.

[0038] In addition, the pinhole (120) may be formed on both sides of the base (110) in a direction in which the frame (100) and another adjacent frame (100) are connected, with a configuration in which the pins are hollow and connected. At this time, the pinholes (120) may be formed at regular intervals in the longitudinal direction, and it is preferable that the pinholes (120) be spaced so that their central axes coincide so that one pin can be connected to each spaced pinhole (120).

[0039] In addition, the pinhole cover (130) may be formed to extend from the base (110). The pinhole cover (130) may be formed in the same direction as the pinhole (120). The pinhole cover (130) may be formed to closely contact and cover the outer surface of the pinhole (120) of an adjacent frame (100). That is, the pinhole cover (130) may serve to cover the gap formed between the pinhole (120) and the base (110) that are connected in a zigzag pattern when the plurality of frames (100) are connected to each other. To this end, the pinhole cover (130) is preferably formed to have a length greater than the gap between the pinholes (120), as illustrated.

[0040] Fig. 3 shows a cross-section of a conveyor (10) according to the present invention. As described above, the frame (100) can be connected and joined in such a way that the pinholes (120) formed at regular intervals in the longitudinal direction and the pinholes (120) of the adjacent frame (100) are interlocked in a zigzag shape to match the insertion openings (121), and one pin is joined to the insertion opening (121).

[0041] At this time, it is preferable that the pinhole (120) and the insertion port (121) are circular so that the angle can flexibly change as the entire conveyor (10) rotates.

[0042] At this time, as the conveyor (10) rotates, it is preferable to form a certain gap (A) as illustrated in order to prevent the pinhole cover (130) from interfering with another adjacent frame (100). That is, as the conveyor (10) rotates, the pinhole cover (130) can slide on the outer surface of the pinhole (120) in the shape of an arc that can be in close contact with the outer surface of the pinhole (120), and can be designed to form a gap (A) as illustrated in order to prevent interference during this operation.

[0043] Fig. 4 is an exploded view of a side wing (200) of a conveyor (10) according to the present invention. As shown, the side wing (200) can be formed in a form in which a first jig (210) and a second jig (220) extend with a step (D).

[0044] To explain in more detail, the side wing (200) can form a step (D) in the form of a flat plate bent in a step shape. That is, the side wing (200) can be formed by extending from the first jig (210) to the second jig (220) so that it can be overlapped and combined with another adjacent side wing (200), and the step (D) can be formed as much as the thickness of the first jig (210) and the second jig (220).

[0045] At this time, for example, the side wing (200) may form jig holes (211, 221) at the lower ends of the first jig (210) and the second jig (220), respectively. It is preferable that the jig holes (211, 221) be coupled coaxially with the insertion hole (121) of the pin hole (120). That is, as described above, they may be coupled together through the pin while being coupled to the side of the frame (100).

[0046] In addition, the side wing (200) may form an inclined portion (201) at a location where the first jig (210) and the second jig (220) are connected. The inclined portion (201) may extend in the longitudinal direction of the side wing (200) and may form a certain angle with the upper and lower surfaces of the side wing (200). This is to prevent the side wing (200) adjacent to and connected to the side wing (200) from interfering with each other when the conveyor (10) rotates around the jig hole (211, 221) and the gap therebetween.

[0047] In addition, the side wing (200) may further include a mounting portion (230) protruding in the direction in which the frame (100) is coupled to the lower portion. The mounting portion (230) is where the frame (100) is mounted, and is preferably coupled so as to be in contact with the lower surface of the frame (100). That is, the mounting portion (230) is configured to reinforce the gap between the frame (100) and the side wing (200) while distributing the load applied to the pin, thereby making the conveyor (10) more solid.

[0048] At this time, the fixing portion (230) may be directly coupled to the frame (100) as a modified example. That is, the side wing (200) may be coupled to the side of the frame (100) in a form in which the fixing portion (230) is directly fastened to the frame (100) in addition to the coupling by the pin as described above. In this modified example, an embodiment without the jig hole (211, 221) may also be included.

[0049] Fig. 5 illustrates a state in which a side wing (200) of a conveyor (10) according to the present invention is connected. As illustrated, the side wing (200) can be connected in a form in which it shares the pin with another side wing (200) that is connected adjacently through a jig hole (211, 221). That is, the pin connected to the pin hole (120) can be connected in a form in which it penetrates both the jig hole (211) of the first jig (210) of the corresponding side wing (200) and the jig hole (221) of the second jig (220) of the adjacent other side wing (200).

[0050] At this time, it is preferable that the jig hole (211, 221) be formed in a circular shape so that it can rotate around the pin. That is, the side wing (200) can rotate with respect to another adjacent side wing (200) around the jig hole (211, 221).

[0051] At this time, as described above, the side wing (200) may interfere with another adjacent side wing (200) while being connected with a step therebetween. To prevent this, an inclined portion (201) that forms a certain angle with the upper and lower surfaces of the side wing (200) may be further included.

[0052] At this time, the upper side (202) of the side wing (200) may be formed to protrude laterally to minimize the gap with the inclined portion (201). In addition, the upper surface (202-1) of the side wing (200) has a shape in which the height gradually decreases in both directions, so that when the side wing (200) rotates around the jig hole (211, 221), it is possible to maintain a minimum gap with the inclined portion (201) of another adjacent side wing (200) while preventing interference.

[0053] At this time, it is preferable that the upper side (202) of the side wing (200) is adjacent to the inclined portion (201) in the opposite direction from where it is combined with the frame (100). This is to prevent the transported material from getting caught in the gap described above.

[0054] In addition, the lower side (203) of the side wing (200) may be designed to be in contact with the inclined portion (201). This is a structure to prevent a gap from occurring in the inner side in the direction of combination with the frame (100) for which the transported material may be caught for the same reason as described above, and the lower side (203) preferably has a curved shape so that when the side wing (200) rotates with respect to the jig hole, the inclined portion (201) of another adjacent side wing (200) can be in contact and slide.

[0055] Fig. 6 illustrates a frame (100) according to another embodiment of the present invention. As illustrated, the frame (100) may include at least one of a reinforcing portion (111), a protrusion (112), a discharge hole (113), and a protrusion hole (114) in which the protrusion and the discharge hole are combined on the base (110).

[0056] Referring to FIG. 6a, the base (110) may further include a reinforcing member (111). The reinforcing member (111) is intended to reinforce the twisting or bending of the entire base (110) against a transported object that applies force while falling or being transported, and as illustrated, may be formed to extend in the longitudinal direction of the base (110) so that the center of the base (110) becomes thicker.

[0057] In addition, the base (110) may form a plurality of protrusions (112). The protrusions (112) may be formed in a dimple shape and distributed throughout the upper surface of the base (110) that comes into contact with the material to be transported. The protrusions (112) are intended to prevent chips or material to be transported from adhering to the upper surface of the flat base (110) during the cutting process due to cutting oil or the like.

[0058] Referring to Fig. 6b, the base (110) can form a plurality of discharge holes (113). The discharge holes (113) are for discharging unnecessary liquids that fall together with the transported material, such as cutting oil, and are preferably formed so as to penetrate the base (110) and discharge the liquid downward.

[0059] Referring to FIG. 6c, the base (110) may include a protruding hole (114, 114-1) in the form of a combination of the above-described protrusion and discharge hole. The protruding hole (114, 114-1) may be designed to protrude upward from the base (110) and further include a through hole so that liquid can be discharged downward from the protruding portion. For example, the protruding hole (114, 114-1) may be formed as a hole in the form of a hemispherical protrusion as shown and penetrating downward from the side.
