Description

Technology Field

[0001] The present invention relates to a scrap processing apparatus and method for a manufacturing process of a laminar member for a motor core. More specifically, the present invention relates to a scrap processing apparatus and method for processing strip-shaped scrap generated in a process of manufacturing a laminar member for motor core lamination by blanking a metal strip material such as an electrical steel sheet, wherein the scrap, having a plurality of blanking openings formed by the separation of the laminar member, is divided and cut using a horizontal cutter blade and a vertical cutter blade disposed in a press unit, thereby enabling the scrap to be divided and discharged into a plurality of fragmented scrap pieces. Background Technology

[0002] Generally, a motor core is manufactured by continuously conveying a metal strip material, such as an electrical steel sheet, to a press device, blanking a plurality of laminar members using a press mold, and then stacking the laminar members. In this specification, "lamina member" refers to a plate-shaped member that is blanked and separated from a metal strip material, such as an electrical steel sheet, and then stacked to form a motor core.

[0003] In the blanking process of such a laminar member, the laminar member is punched out and separated from the metal strip material, and a blanking opening is formed at the location where the laminar member is separated.

[0004] Accordingly, after the blanking process, a strip-shaped scrap having multiple blanking openings remains. At this time, the strip-shaped scrap may include a horizontal bridge scrap formed between adjacent blanking openings in the conveying direction and a vertical bridge scrap formed between adjacent blanking openings in the width direction.

[0005] The above blanking openings can be arranged in two rows on strip-shaped scrap to increase material utilization. In this case, the blanking openings of the upper and lower rows can be arranged in a zigzag shape offset from each other in the conveying direction.

[0006] This two-row zigzag arrangement can reduce the empty space between adjacent blanking openings, thereby improving the material utilization rate of electrical steel sheets and reducing the scrap area generated after blanking.

[0007] However, the strip-shaped scrap remaining after blanking has multiple blanking openings while maintaining an overall long, connected band shape. Therefore, if this strip-shaped scrap is discharged as is, it may get curled or bent during the discharge process, overlap or get tangled inside the discharge container, and cause jamming in the discharge path or at the entrance of the discharge container.

[0008] Furthermore, when scrap in the form of strips is discharged in a long, connected state, the volume occupied inside the discharge container increases relative to the actual weight of the scrap, thereby reducing the container's effective capacity. Consequently, operators must frequently empty the discharge container, and the continuous operation of the production line may be degraded due to scrap jamming or accumulation.

[0009] In order to resolve this, conventionally, as shown in FIG. 4, a method was used in which a scrap cutting means was installed at the end of the blanking process in the manufacturing process of a laminar member.

[0010] For example, a vertical cutting section (N) equipped with a vertical cutter blade (N') is installed in a press section that is not shown in the drawing, and while intermittently conveying a strip-shaped scrap (S) generated through a blanking process over a certain length, the scrap (S) is cut in the vertical direction using the vertical cutter blade (N') of the vertical cutting section (N), thereby dividing the scrap (S) into scrap pieces (P) of a certain width and discharging them.

[0011] However, since this conventional method is structured to cut the strip-shaped scrap (S) in only one direction using a vertical cutter blade (N'), there is a limitation in dividing the scrap (S) into sufficiently small fragment scrap pieces (P).

[0012] In particular, the strip-shaped scrap (S) having a two-row zigzag arrangement of blanking openings (H) has an upper row blanking opening (H1) and a lower row blanking opening (H2) formed so as to be offset from each other in the conveying direction.

[0013] Therefore, since the conventional vertical cutting section (N) is structured to cut the scrap (S) only in the vertical direction, it is difficult to effectively cut the horizontal bridge scrap (B1) formed between adjacent blanking openings (H) in the conveying direction.

[0014] In addition, scrap pieces (P) cut by the conventional method may maintain a relatively long shape in the conveying direction even if they are partially divided in the width direction. Accordingly, even after cutting, problems may still occur where the scrap pieces (P) curl up or bend during the discharge process, or overlap or get tangled inside the discharge container.

[0015] Furthermore, because the size of the scrap pieces (P) is not sufficiently small, it is difficult to load them densely inside the discharge container, and there are limitations in sufficiently increasing the actual capacity of the discharge container. As a result, it is difficult to sufficiently extend the scrap removal cycle of the operator, and it is difficult to fundamentally eliminate the possibility of production line stoppage due to scrap jamming or accumulation.

[0016] Meanwhile, various scrap cutting technologies are known for improving scrap extraction or breaking scrap into smaller pieces.

[0017] For example, Korean Registered Patent No. 10-0435701 discloses a scrap cutting technology for improving the ejectability of scrap generated during a press forming process, and Japanese Registered Patent Publication No. 5067000 discloses a technology for cutting waste material generated during a trimming process into multiple pieces.

[0018] However, the above technologies are not intended for strip-shaped scrap generated after blanking of a laminar member for a motor core, and differ from technologies that divide and cut bridge scrap formed between multiple blanking openings into fragment scrap pieces in the horizontal and vertical directions.

[0019] Therefore, there is a need for a technology that can improve discharge and acceptance efficiency by dividing the strip-shaped scrap generated during the manufacturing process of laminar components for motor cores into smaller fragment scrap pieces.

[0020] The present invention aims to satisfy these requirements by providing a scrap processing device and method capable of discharging a plurality of fragmented scrap pieces by dividing and cutting strip-shaped scrap generated during the manufacturing process of a laminar member for a motor core using a horizontal cutter blade and a vertical cutter blade arranged in a press section. The problem to be solved

[0021] The present invention aims to provide a scrap processing apparatus and method capable of stably dividing and cutting strip-shaped scrap generated after blanking of a laminar member for a motor core into a plurality of fragmentary scrap pieces.

[0022] In particular, the present invention aims to provide a scrap processing apparatus and method capable of dividing a strip-shaped scrap having a plurality of blanking openings into sufficiently small fragment scrap pieces by using a transverse cutter blade and a longitudinal cutter blade to cut the transverse bridge scrap and the longitudinal bridge scrap, respectively.

[0023] In addition, the present invention aims to provide a scrap processing device and method capable of cutting a first horizontal bridge scrap and a second horizontal bridge scrap, respectively, formed at different pitch positions corresponding to blanking openings arranged in a two-row zigzag shape.

[0024] In addition, the present invention aims to provide a scrap processing device and method that can suppress the curling, bending, overlapping, entanglement, and jamming of scrap by dividing strip-shaped scrap into fragment scrap pieces and discharging them, and improve the receiving efficiency of the discharge container, the scrap removal cycle, the continuous operation of the production line, and the automatic discharge stability.

[0061] According to the present invention, by dividing and cutting the strip-shaped scrap generated after blanking of a laminar member for a motor core using a horizontal cutter blade and a vertical cutter blade, the scrap can be stably fragmented into a plurality of fragment scrap pieces.

[0062] In addition, according to the present invention, since the horizontal bridge scrap formed between adjacent blanking openings in the conveying direction and the vertical bridge scrap formed between adjacent blanking openings in the width direction can be cut respectively, the size of the scrap pieces can be formed smaller compared to the conventional unidirectional cutting method.

[0063] In addition, according to the present invention, since a first horizontal bridge scrap and a second horizontal bridge scrap formed at different pitch positions corresponding to a blanking opening arranged in a two-row zigzag shape can be cut respectively, stable split cutting is possible even for scraps arranged in a zigzag shape.

FIG. 4 is a schematic plan view showing the state of cutting a strip-shaped scrap using a vertical cutting section according to the prior art. Specific details for implementing the invention

[0069] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described below and may be modified and implemented in various forms within the scope of the technical spirit of the present invention.

[0070] FIG. 1 is a schematic front view of a scrap processing device (100) for a manufacturing process of a laminar member for a motor core according to the present invention, FIG. 2 is a schematic plan view for explaining the scrap processing state according to the present invention, and FIG. 3 is a plan view sequentially showing the state in which a strip-shaped scrap (10) is divided and cut into a plurality of fragment scrap pieces (10A) through the scrap processing device (100) according to the present invention.

[0071] Referring to FIGS. 1 to 3, the scrap processing device (100) according to the present invention may include a material conveying unit (not illustrated) for conveying a metal strip material such as an electrical steel sheet, a press unit (110) for pressing the metal strip material to blank a laminar member for a motor core, a scrap discharge unit (not illustrated) for guiding a strip-shaped scrap (10) generated after the laminar member is blanked in a discharge direction, and a scrap cutting unit (120) for dividing and cutting the strip-shaped scrap (10) into a plurality of fragment scrap pieces (10A).

[0072] The metal strip material may be an electrical steel sheet for manufacturing a laminar member for a motor core. The metal strip material may be continuously or intermittently transported to a press unit (110) by a material transport unit, and the material transport unit may be configured to transport the metal strip material in units of a certain pitch.

[0073] The above press unit (110) may include an upper die (111) and a lower die (112). An unillustrated blanking die unit for blanking a laminar member may be provided at the front end of the press unit (110).

[0074] The above blanking die presses the metal strip material to punch out a laminar member. When the laminar member is separated from the metal strip material, a blanking opening (11) corresponding to the shape of the laminar member is formed in the metal strip material.

[0075] Accordingly, after the blanking process, a strip-shaped scrap (10) having a plurality of blanking openings (11) remains. The strip-shaped scrap (10) is waste material remaining after the laminar member is punched out, and can maintain a long, connected strip shape overall.

[0076] The blanking openings (11) may be arranged in two rows in a strip-shaped scrap (10). In this case, the blanking openings (11) may include an upper row blanking opening (11A) and a lower row blanking opening (11B).

[0077] The upper row blanking opening (11A) and the lower row blanking opening (11B) can be arranged in a zigzag shape offset from each other in the conveying direction to increase material utilization. By such a two-row zigzag arrangement, the empty space between adjacent blanking openings (11) can be reduced, thereby improving the material utilization of the electrical steel sheet and reducing the area of ​​scrap generation.

[0078] Bridge scraps may be formed between blanking openings (11) in the strip-shaped scrap (10) above. Specifically, a first horizontal bridge scrap (11C) may be formed between upper row blanking openings (11A), and a second horizontal bridge scrap (11D) may be formed between lower row blanking openings (11B). Additionally, a vertical bridge scrap (11E) may be formed between adjacent upper row blanking openings (11A) and lower row blanking openings (11B) in the width direction.

[0079] The scrap discharge unit guides the strip-shaped scrap (10) generated after the blanking process in a discharge direction. The scrap discharge unit may be positioned at the rear end of the press unit (110) and may guide the strip-shaped scrap (10) to pass through the scrap cutting unit (120).

[0080] The scrap cutting section (120) may be placed in the press section (110). The scrap cutting section (120) may include a horizontal cutting section (121) that cuts the strip-shaped scrap (10) in the width direction and a vertical cutting section (122) that cuts the strip-shaped scrap (10) in the conveying direction.

[0081] The above-mentioned horizontal cutting section (121) may include a horizontal cutter blade (121A). The horizontal cutter blade (121A) may be positioned to extend along the width direction of the strip-shaped scrap (10) and may cut the first horizontal bridge scrap (11C) and the second horizontal bridge scrap (11D).

[0082] The above horizontal cutter blade (121A) may be installed in either the upper die (111) or the lower die (112) of the press part (110). The horizontal cutting support part (121B) corresponding to the above horizontal cutter blade (121A) may be installed in the other of the upper die (111) and the lower die (112).

[0083] For example, the horizontal cutter blade (121A) may be installed in the upper die (111), and the horizontal cutting support (121B) may be installed in the lower die (112). In this case, when the upper die (111) descends, the horizontal cutter blade (121A) engages with the horizontal cutting support (121B) to cut the strip-shaped scrap (10) in the width direction.

[0084] When the blanking openings (11) are arranged in a two-row zigzag shape, the upper row blanking openings (11A) and the lower row blanking openings (11B) may be formed at pitch positions offset from each other in the conveying direction.

[0085] In this case, the horizontal bridge scrap may include a first horizontal bridge scrap (11C) formed between upper column blanking openings (11A) and a second horizontal bridge scrap (11D) formed between lower column blanking openings (11B), and the first horizontal bridge scrap (11C) and the second horizontal bridge scrap (11D) may be formed at different pitch positions.

[0086] In this case, the horizontal cutter blade (121A) may include a first horizontal cutter blade (121A') and a second horizontal cutter blade (121A"). The first horizontal cutter blade (121A') may be positioned at a location corresponding to the first horizontal bridge scrap (11C) between the upper column blanking openings (11A), and the second horizontal cutter blade (121A") may be positioned at a location corresponding to the second horizontal bridge scrap (11D) between the lower column blanking openings (11B).

[0087] Accordingly, even if the first horizontal bridge scrap (11C) and the second horizontal bridge scrap (11D) are formed at different pitch positions by a two-row zigzag arrangement, each horizontal bridge scrap (11C, 11D) can be stably cut through the first horizontal cutter blade (121A') and the second horizontal cutter blade (121A").

[0088] The above-mentioned vertical cutting section (122) may include a vertical cutter blade (122A). The vertical cutter blade (122A) may be positioned to extend along the conveying direction of the strip-shaped scrap (10), and the cutting line of the vertical cutter blade (122A) may be formed along the conveying direction.

[0089] Accordingly, the vertical cutter blade (122A) can cut the vertical bridge scrap (11E) formed between adjacent blanking openings (11) in the width direction, thereby separating the strip-shaped scrap (10) in the width direction.

[0090] The vertical cutter blade (122A) may be installed in either the upper die (111) or the lower die (112) of the press part (110). The vertical cutting support part (122B) corresponding to the vertical cutter blade (122A) may be installed in the other of the upper die (111) and the lower die (112).

[0091] For example, the vertical cutter blade (122A) may be installed in the upper die (111), and the vertical cutting support (122B) may be installed in the lower die (112). In this case, when the upper die (111) descends, the vertical cutter blade (122A) engages with the vertical cutting support (122B) and can cut the strip-shaped scrap (10) in the conveying direction.

[0092] The above horizontal cutter blade (121A) and vertical cutter blade (122A) can be operated in conjunction with the downward movement of the upper die (111) of the press unit (110). Accordingly, even without installing a separate independent post-processing device, the strip-shaped scrap (10) can be divided and cut in conjunction with the blanking process of the laminar member.

[0093] Additionally, the cutting line formed by the horizontal cutter blade (121A) and the cutting line formed by the vertical cutter blade (122A) can form a multi-segment cutting pattern that intersects each other. Accordingly, the strip-shaped scrap (10) can be cut in the width direction and the conveying direction, respectively, and divided into a plurality of open fragment scrap pieces (10A).

[0094] The above-mentioned fragment scrap piece (10A) may be formed in the shape of a relatively small piece rather than a long strip. Accordingly, the phenomenon of the fragment scrap piece (10A) curling or bending during the discharge process is reduced, and the phenomenon of overlapping or tangling inside the discharge container can also be suppressed.

[0095] In addition, the above-mentioned fragment scrap pieces (10A) can be densely packed inside the discharge container, thereby increasing the actual capacity of the discharge container. Accordingly, the scrap removal cycle of the operator can be extended, and the possibility of the production line stopping due to scrap jamming or accumulation can be reduced.

[0096] Next, a scrap processing method according to the present invention will be described.

[0097] FIG. 3 is a cutting flowchart illustrating a scrap processing method according to the present invention.

[0098] First, a metal strip material, such as an electrical steel sheet, is transferred to a blanking die section using a material transfer section, and the metal strip material is blanked using the blanking die section to punch out and separate a laminar member. At this time, a blanking opening (11) is formed at the location where the laminar member is separated, and after the blanking process, a strip-shaped scrap (10) having a plurality of blanking openings (11) remains.

[0099] Next, the strip-shaped scrap (10) is transferred to a press unit (110) in which a scrap cutting unit (120) is placed.

[0100] Next, a strip-shaped scrap (10) is cut in the width direction using the first horizontal cutter blade (121A') and the second horizontal cutter blade (121A") of the horizontal cutting section (121) positioned in the press section (110). At this time, the first horizontal cutter blade (121A') cuts the first horizontal bridge scrap (11C) between the upper row blanking openings (11A), and the second horizontal cutter blade (121A") can cut the second horizontal bridge scrap (11D) between the lower row blanking openings (11B) (see FIG. 3(a)).

[0101] Next, a strip-shaped scrap (10) is cut in the conveying direction using a vertical cutter blade (122A) of a vertical cutting section (122) positioned in a press section (110). At this time, the vertical cutter blade (122A) can cut a vertical bridge scrap (11E) formed between adjacent blanking openings (11) in the width direction (see FIG. 3 (b)).

[0102] In this way, by performing width-direction cutting with the first and second transverse cutter blades (121A', 121A") and feed-direction cutting with the longitudinal cutter blade (122A), the strip-shaped scrap (10) is divided into a plurality of fragment scrap pieces (10A) (see (c) of FIG. 3).

[0103] At this time, the above-mentioned fragment scrap piece (10A) may include a portion of the perimeter of the upper column blanking opening (11A) or the lower column blanking opening (11B), and as the horizontal bridge scrap and the vertical bridge scrap (11E) are cut, the blanking opening (11) may have a cut shape in which a portion of it is opened outward.

[0104] That is, the above-mentioned fragment scrap piece (10A) may be formed in a shape that is not an annular or closed curve shape in which the entire circumference of the blanking opening (11) is closed, but rather a piece shape in which a part of the circumference of the blanking opening (11) communicates with the outside by a cutting line. Accordingly, the external dimensions of the above-mentioned fragment scrap piece (10A) are smaller compared to the shape of a long strip, and curling, overlapping, and entanglement can be further suppressed during the discharge process.

[0105] Next, the above-mentioned scrap piece (10A) is discharged into a discharge container.

[0106] Accordingly, according to the present invention, a strip-shaped scrap (10) of a manufacturing process for a laminar member for a motor core can be stably divided and cut into small fragment scrap pieces (10A), thereby achieving a reduction in the volume of the scrap, an increase in the discharge container capacity, an extension of the scrap removal cycle, a reduction in scrap jamming, and an improvement in automatic discharge stability.

[0107] It should be understood that the description of the invention provided above is merely illustrative for the purpose of understanding the invention and is not intended to define the scope of protection of the invention. The scope of protection of the invention is defined by the appended claims, and within this scope, simple variations or modifications of the invention shall be interpreted as falling within the scope of rights of the invention.
