Description

TECHNICAL FIELD

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

[0002] Along with the development of modern technology, metal materials used in various fields have also achieved great development. While common steel materials were widely used in the past, in recent years, in order to improve the durability of mechanical parts such as those for automobiles, carbon steel containing carbon and various special steels with increased strength have been gradually adopted.

[0003] In order to handle such high-strength materials, peripheral equipment required for product production such as processing and conveying also need gradual improvement, which leads to the problem that the cost for modification or manufacturing of the peripheral equipment increases significantly.

[0004] For the same reason as described above, conveyors mainly used for conveying materials or products also cannot avoid such problems. In the case of chain-shaped conveyors, there has been a problem that high-strength conveyed objects are caught in the gaps between chains, inducing damage to the conveyor itself.

[0005] In particular, when high-strength material waste, scraps, aggregates or irregular fine chips generated after processing remain caught in the narrow gaps between hinges of the conveyor and the conveyor continues to rotate, wear progresses gradually, the gaps expand and eventually lead to damage, which has been a problem. SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION

[0026] The technical concept of the present invention will be described in more detail below with reference to the accompanying drawings. First, terms or words used in this specification and in the claims should not be interpreted in a way that is limited to their ordinary or dictionary meanings. Rather, based on the principle that inventors can appropriately define the concepts of terms to best describe their invention, they should be interpreted in a way that is consistent with the technical concept of the present invention. Therefore, it should be understood that the embodiments described herein and the configurations shown in the drawings represent only one of the most preferred embodiments of the present invention and do not represent the entire technical concept of the present invention; therefore, various modifications may exist that can substitute them at the time of filing.

[0027] Figure 1 is a perspective view showing a part of a conveyor 10 according to the present invention. As shown, the conveyor 10 may broadly include a frame 100, side wings 200, and a chain.

[0028] More specifically, the conveyor 10 may include a configuration in which multiple frames 100, side wings 200, and chains 300 of the same shape are connected. The frame 100 may include a configuration that allows it to be connected to other adjacent frames 100 in a plate-like configuration.

[0029] Furthermore, the side wings 200 are intended to prevent the conveyed objects being transported on the conveyor 10 from detaching to the side or from being caught in the components located on the side of the conveyor 10, and can be connected to the side of the multiple connected frames 100 in a direction perpendicular to the connection direction. In this case, the side wings 200 may be configured in a way that multiple side wings overlap and extend, as shown in the figure.

[0030] Furthermore, the chain 300 is configured to be connected to a drive device so that the conveyor 10 can rotate, and can be extended by being connected to the other side of the side wing 200 that is connected to the frame 100.

[0031] Figure 2 shows 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.

[0032] More specifically, the frame 100 may include a flat, plate-shaped base 110. The base 110 may provide a space for the conveyed object to settle.

[0033] Furthermore, the pinholes 120 are hollowed out to accommodate pins, and can be formed on both ends of the base 110 in a direction that connects the frame 100 to other adjacent frames 100. In this case, the pinholes 120 may be formed at regular intervals in the longitudinal direction, and it is preferable that they be drilled so that their central axes coincide with each other, allowing one pin to be connected to each pinhole 120.

[0034] Furthermore, the pinhole cover 130 may be formed as an extension on 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 cover the outer circumferential surface of the pinhole 120 of an adjacent frame 100. That is, when the multiple frames 100 are connected to each other, the pinhole cover 130 can serve to cover the gap formed between the pinhole 120 and the base 110, which are connected in a zigzag pattern. For this purpose, it is preferable that the pinhole cover 130 be formed to be longer than the distance between the pinholes 120, as shown in the figure.

[0035] Figure 3 shows a cross-section of the conveyor 10 according to the present invention. As described above, the frames 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 adjacent frames 100 interlock in a zigzag pattern to align the insertion openings 121, and one pin is connected to the insertion opening 121.

[0036] In this case, it is preferable that the pinhole 120 and the insertion opening 121 are circular so that their angles can flexibly change as the entire conveyor 10 rotates.

[0037] At this time, in order to prevent the pinhole cover 130 from interfering with other adjacent frames 100 as the conveyor 10 rotates, it is preferable to form a certain gap A as shown in the figure. That is, the pinhole cover 130 can slide on the outer surface of the pinhole 120 as the conveyor 10 rotates in an arc shape that can be in close contact with the outer surface of the pinhole 120, and can be designed to form a gap A as shown to prevent interference during such operation.

[0038] Figure 4 shows an exploded view of the side wing 200 of the conveyor 10 according to the present invention. As shown in the figure, the side wing 200 may be formed such that the first jig 210 and the second jig 220 extend with a step D.

[0039] More specifically, the side wing 200 can form a step D in the form of a flat plate that is curved in a stepped manner. That is, the side wing 200 is formed to extend from the first jig 210 to the second jig 220 so that it can overlap and connect with other adjacent side wings 200, and can form a step D equal to the thickness of the first jig 210 and the second jig 220.

[0040] In this case, as an example, the side wing 200 may have jig holes 211 and 221 formed at the lower ends of the first jig 210 and the second jig 220, respectively. Preferably, the jig holes 211 and 221 are connected so as to be coaxial with the insertion opening 121 of the pinhole 120. That is, as described above, they can be connected together via the pin while being connected to the side of the frame 100.

[0041] Furthermore, the side wing 200 may have an inclined portion 201 at the position where the first jig 210 and the second jig 220 are connected. The inclined portion 201 extends 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 minimize the gap between side wings 200 that are connected adjacent to each other and rotate around the jig holes 211 and 221 while the conveyor 10 rotates.

[0042] Furthermore, the side wing 200 may further include a mounting portion 230 that protrudes in the direction to which the frame 100 is joined to the lower part. The mounting portion 230 is the place where the frame 100 is attached, and it is preferable that it is joined so as to be in contact with the lower surface of the frame 100. In other words, the mounting portion 230 is intended to distribute the load on the pin while reinforcing the gap between the frame 100 and the side wing 200, and this configuration makes the conveyor 10 more robust.

[0043] In this case, the anchoring portion 230 can be directly connected to the frame 100 as a modified example. That is, in addition to the connection by pins as described above, the side wing 200 can be connected to the side of the frame 100 by the anchoring portion 230 being directly fastened to the frame 100. Such modified examples may include embodiments in which the jig holes 211 and 221 are absent.

[0044] Figure 5 shows how the side wings 200 of the conveyor 10 according to the present invention are connected. As shown in the figure, the side wings 200 can be connected to other adjacent side wings 200 in a manner that they share the pins via jig holes 211 and 221. That is, the pin connected to the pin hole 120 can be connected in a manner that 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.

[0045] In this case, it is preferable that the jig holes 211 and 221 are formed in a circular shape so that they can rotate around the pin. That is, the side wing 200 can rotate around the jig holes 211 and 221 relative to other adjacent side wings 200.

[0046] In this case, as described above, the side wings 200 may interfere with each other as they overlap and are connected with adjacent side wings 200 with a step difference. To prevent this, the side wings 200 may further include inclined portions 201 that form a certain angle with the upper and lower surfaces of the side wings 200.

[0047] In this case, the upper side end 202 of the side wing 200 may be formed to protrude laterally in order to minimize the gap with the inclined portion 201. Furthermore, the upper surface 202-1 of the side wing 200 has a shape that gradually decreases in height in both directions, so that when the side wing 200 rotates around the jig holes 211 and 221, interference with the inclined portion 201 of other adjacent side wings 200 can be prevented while maintaining a minimum gap.

[0048] In this case, it is preferable that the upper side end 202 of the side wing 200 contacts the inclined portion 201 in the direction opposite to the direction in which it is connected to the frame 100. This is to prevent the conveyed object from getting caught in the aforementioned gap.

[0049] Furthermore, the lower side end 203 of the side wing 200 can be designed to contact the inclined portion 201. This is a structure to prevent a gap from occurring in which the conveyed object is pinched on the inside in the direction in which it is coupled with the frame 100, for the same reasons as described above. Preferably, the lower side end 203 is curved so that when the side wing 200 rotates relative to the jig hole, the inclined portion 201 of an adjacent side wing 200 can come into contact with and slide against it.

[0050] Figure 6 shows frames 100 according to other embodiments of the present invention. As shown, the frame 100 may include at least one of a reinforcing portion 111, a projection 112, a discharge hole 113, and a projection hole 114 in which the projection and the discharge hole are joined.

[0051] Referring to Figure 6a, the base 110 may further include a reinforcing portion 111. The reinforcing portion 111 is for reinforcing the entire base 110 against twisting or bending when a transported object is subjected to force during dropping or transport, and may be formed to extend in the longitudinal direction of the base 110 and thicken the center of the base 110, as shown in the figure.

[0052] Furthermore, the base 110 may have a plurality of protrusions 112. These protrusions 112 may be formed in a dimple shape and distributed evenly across the upper surface of the base 110 that comes into contact with the conveyed material. The purpose of these protrusions 112 is to prevent chips generated during the cutting process and conveyed material from adhering to the flat upper surface of the base 110 due to cutting fluid or the like.

[0053] Referring to Figure 6b, the base 110 may have a plurality of discharge holes 113. The discharge holes 113 are for discharging unwanted liquids that fall along with the conveyed material such as cutting oil, and it is preferable that they are formed so that the liquid can be discharged downwards by penetrating from the base 110.

[0054] Referring to Figure 6c, the base 110 may include protruding holes 114, 114-1 in which the aforementioned protrusions and discharge holes are combined. The protruding holes 114, 114-1 protrude upward on the base 110, but can be designed to include a hole that penetrates through the protruding portion so that liquid is discharged downward. As an example, the protruding holes 114, 114-1 may form a hole that protrudes in a hemispherical shape and penetrates downward from the side, as shown in the figure. [Industrial applicability]
