Description

High-speed, high-efficiency material transport system

[0001] The present invention relates to a high-speed, high-efficiency material transfer system in which material transfer efficiency is maximized by simultaneously performing material transfer and removal by first and second material suction and removal means installed as a pair on the left and right and performing positive and negative rotational and linear reciprocating movements, and press productivity is greatly improved by high-speed transfer.

[0002] In general, a press automation system achieves press automation by repeating the following processes: an input process in which the press material loaded in the material supply device is absorbed and transported and then fed into the next press (press machine) mold, a stamping (forming) process in which the material fed into the mold is pressed out by the press, an ejection (discharge) process in which the stamped material is discharged from the mold, and a process in which the discharged material is transported to the next press, fed in, and then stamped and discharged.

[0003] On the other hand, when the press material is small and light, the worker can load and unload the press material into the mold by hand, but this requires a lot of workers, and not only does it cause musculoskeletal disorders in the workers due to repetitive work, but it also reduces productivity and poses a risk of safety accidents. Therefore, some people rely on expensive multi-joint robots to transport, load, and unload press materials. However, the arm length of the multi-joint robot that attaches and detaches the material is long and the working radius is large, so not only does the installation gap between presses increase, but the structure also makes the movement path of the material between processes longer, which reduces speed and productivity, and requires a lot of equipment and maintenance costs, resulting in low profitability, and other problems.

[0004] The problem to be solved by the present invention is to provide a high-speed, high-efficiency material transfer system in which material input and output are simultaneously performed by first and second material suction and desorption means installed as a pair on the left and right and performing a positive and negative rotational motion and a linear reciprocating motion, thereby maximizing transfer efficiency and greatly improving press productivity through high-speed transfer.

[0005] The high-speed, high-efficiency material transport system of the present invention comprises: a base having a plurality of height adjustment means, a top plate installed horizontally on the top of the base, a turntable installed on the upper surface of the top plate and rotating forward and backward by a driving motor and a power transmission means, a rotary plate installed on the upper surface of the turntable and rotating forward and backward, a first LM guide and a first rack gear installed in parallel to the rear of the upper surface of the rotary plate, a second LM guide and a second rack gear installed in parallel to the front of the upper surface of the rotary plate, a first transport unit installed on the first LM guide, a first servo motor installed on the first transport unit, a first gear fixed to the rotational axis of the first servo motor and gear-engaged with the first rack gear, a first lifting unit installed on one side of the first transport unit, a first arm installed horizontally on the first lifting unit and moving up and down by a second servo motor and a power transmission means, and a first arm detachably attached to an end of the first arm.

[0006] The distance between the first arm and the second arm may be 10 to 500 mm so that the first arm and the second arm do not come into contact with or interfere with each other when the first arm and the second arm are raised and lowered and moved forward and backward (or moved left and right) to load, load, and transport materials.

[0007] The above turntable includes an outer fixing ring fixed to the upper surface of the upper plate with a plurality of fixing members, an inner ring that is freely rotatable forward and backward by being joined to the inner surface of the outer fixing ring with a plurality of steel balls, an inner ring gear formed on the entire inner surface of the inner ring, a turntable fixed to the upper surface of the inner ring with a plurality of fixing members, and a pinion gear that is fixed to the rotation shaft of a driving motor fixed to the upper plate and is gear-coupled to the inner ring gear.

[0008] The first and second lifting units above include first and second vertical plates installed on one side of the first and second transport units, a plurality of first and second LM rails and first and second ball screws installed vertically and parallel to the front surface of the first and second vertical plates, first and second LM blocks coupled to the plurality of first and second LM rails and slidingly moving, first and second arms installed horizontally on the front surface of the first and second LM blocks, first and second brackets fixed to the upper and lower portions of one side surface of the first and second vertical plates and having the upper and lower portions of the first and second ball screws axially installed, a driven timing pulley fixed to the lower portion of the first and second ball screws, first and second driving timing pulleys fitted and fixed to the rotational shafts of the second and fourth servo motors installed in the first and second transport units, a timing belt connecting the driving timing pulley and the driven timing pulley, and first and second arms. It includes first and second ball nuts that are fixed and screw-connected to first and second ball screws, and first and second material absorption and desorption means that are detachably installed at the ends of the first and second arms and absorb and desorb press materials.

[0009] It further includes stoppers installed on both sides of the upper surface of the above-mentioned rotating plate to prevent the first and second transfer units from coming off.

[0010] The upper surface of the inner ring may be characterized by protruding 3 to 100 mm higher than the upper surface of the outer fixed ring.

[0011] It may further include an auxiliary ring inserted and fixed between the inner ring and the rotating plate.

[0012] The upper surface of the upper plate may further include a buffer member installed on both sides, and a stopper installed on one side of the lower surface of the turntable to prevent the turntable from rotating excessively by the buffer member.

[0013] The rotation angle of the above turntable can be 180 to 270°.

[0014] The above first and second gears and the first and second rack gears may be spur gears or helical gears.

[0015] The first and second material adsorption and desorption means include first and second grippers having joints installed at predetermined intervals, a support rod fitted to the joints and having an inclination adjusted, a plurality of vacuum adsorption pads or electromagnets fixed to the ends of the support rods and adsorbing and desorbing materials, and a material detection sensor installed on one side of the plurality of vacuum adsorption pads or electromagnets and detecting adsorption and desorption of materials.

[0016] It further includes stoppers installed on both sides of the upper surface of the above-mentioned rotating plate to prevent the first and second transfer units from coming off.

[0017] The upper surface of the upper plate further includes a buffer member installed on both sides, and a stopper installed on one side of the lower surface of the turntable to prevent the turntable from rotating excessively by the buffer member.

[0018] The present invention has the effect of maximizing the transfer efficiency and greatly improving press productivity by allowing the material (S) to be simultaneously loaded and unloaded by the first and second material suction and desorption means (18) (25) installed as a pair on the left and right and performing a positive and negative rotational movement and a linear reciprocating movement.

[0019] The present invention has the effect of improving productivity by reducing the radius of rotation when the first and second material adsorption / desorption means (18) (25) rotate by the turntable (6) to rotate and turn, thereby greatly reducing centrifugal force (or rotational inertia) and increasing the transport speed.

[0020] The present invention has the effect that the first arm (17) and the second arm (24) do not come into contact with or interfere with each other when loading, unloading, and transporting materials (S) while moving up, down, forward, and backward (or left and right) since a separation distance (L1) of 10 to 500 mm is maintained.

[0021] The present invention has first and second transport units (12) (19) and first and second lifting units (15) (22) that move in both directions on a rotating plate (7) that rotates forward and backward by a driving motor (5) to transport a material (S), first and second arms (17) (24), and first and second material suction and removal means (18) (25) that rotate and transport the material (S) in the shortest possible distance, thereby maximizing the material transport efficiency.

[0022] The present invention has the effect of providing a smooth rotational motion as well as preventing sagging or vibration since the turntable (6) is firmly supported by a ring bearing that also serves as an axis member, thereby eliminating the need for a separate rotational axis and facilitating the installation of the turntable (6). In addition, even if the center of gravity changes significantly due to the transport of material (S), the turntable (6) is supported horizontally.

[0023] The turntable (6) of the present invention is stably supported by the inner ring (34) and the outer fixing ring (32), so that the phenomenon of control precision deteriorating due to vibration, clearance, left-right vibration, etc. is prevented, and the service life is greatly extended, and maintenance costs are also greatly reduced.

[0024] The present invention is a very useful invention that has the effect of drastically reducing safety accidents caused by workers or workers by automating the import, export, and transport of materials, thereby protecting valuable human lives and property.

[0099] The present invention comprises a first transfer unit (12), a first elevation unit (15), a first arm (17), and a first material suction / desorption means (18) which are installed on the rear side of the upper surface of the turntable (6) rotary plate (7) and independently move, and a second transfer unit (19), a second elevation unit (22), a second arm (24), and a second material suction / desorption means (25) which are installed on the front side of the upper surface of the turntable (6) rotary plate (7) and independently move, so that the material (S) is introduced, removed, and transferred to a front process mold (M1) and a rear process mold (M2) while performing a positive / negative rotational movement or a positive / negative rotational movement and a linear reciprocating movement in both directions (left / right or front / back directions), thereby maximizing the material transfer efficiency.

[0100] The present invention provides a high-speed, high-efficiency material transport system (1) installed between a press machine and a press machine, or between a material supply device and a press machine, or between a press machine and a discharge material loading device, and installed and used to enable the material (S) to be loaded into, removed from, and transported (including discharged) to a mold. The loading, removal, and transport of the material (S) are exemplified in a state of use when the material is loaded into a front-process mold (M1) or a material supply device and a post-process mold (M2), or when the material is punch-molded.

[0101] In the high-speed, high-efficiency material transport system (1) of the present invention, while the first material suction / desorption means (18) enters the front process mold (M1) and takes out the molded material (S1), the second material suction / desorption means (25) rotates 180° in a state of having previously absorbed the material (S2) that has been punch-molded by the front process mold (M1) and then waits near the post-process mold (M2). Accordingly, while the first material suction / desorption means (18) enters the front process mold (M1), absorbs the molded material (S1), and then moves up and backward to take it out, the second material suction / desorption means (25) enters the post-process mold (M2), takes in the material (S2) that has been molded in the front process mold (M1), desorbs it, and then moves up and backward.

[0102] For example, the material (S) introduced into the front process mold (M1) and the post-process mold (M2) of the press machine by the downward punching of the upper mold (not shown) is punched and formed, and the first material suction / desorption means (18) enters the front process mold (M1) to take out the punched material (S) so that it can be transferred to the next process (next forming process or discharge process). At this time, the material (S1) is introduced into the front process mold (M1) by another high-speed, high-efficiency material transfer system (1) installed in the front press machine, and the second material suction / desorption means (25) sucks the material (S2) that has been previously formed by the front process mold (M1), then rotates 180° or pivots 180° to be transferred to the post-process mold (M2), and then moves backward, thereby forming the materials (S) on both sides by the downward punching of the upper mold.

[0103] To explain the above process in more detail, when the material (S) fed into the front process mold (M1) and the post-process mold (M2) is raised to a predetermined height or is raised while the upper mold is being formed by the lowering punch of the upper mold (not shown), the first transfer unit (12), the first arm (17), and the first material suction / desorption means (18) move forward and enter the front process mold (M1) by the forward rotation of the first servo motor (13), and the first lifting unit (15) is lowered by the forward rotation of the second servo motor (16), and the first arm (27) and the first material suction / desorption means (18) are lowered to suck the material (S1) formed by the upper mold and the front process mold (M1), and when detected by the material detection sensor (73), the second servo motor (16) is rotated in reverse to cause the first When the lifting unit (15) rises to a predetermined height and the first arm (24) and the first material suction / desorption means (18) also rise so that the absorbed material (S1) rises to the removal height, the first transfer unit (12), the first arm (17) and the first material suction / desorption means (18) move backward (E direction) by the reverse rotation of the first servo motor (13), and at the same time, the second material suction / desorption means (25) that is sucking the material (S2) previously formed on the front process mold (M1) rotates 180° clockwise (B direction) or pivots (B1 direction) by the forward rotation of the drive motor (5) of the turntable (6) and moves forward and enters (G direction) onto the post-process mold (M2) by the second transfer unit (19) and the second arm (24) by the forward rotation of the third servo motor (20), and the fourth When the second lifting unit (22) is lowered by the forward rotation of the servo motor (23), and the second arm (24) and the second material suction / detachment means (25) are also lowered to detach the material (S2) formed and transported in the previous process and settle it on the post-process mold (M2), and the material detection sensor (73) detects this, the second lifting unit (22) is raised by the reverse rotation of the fourth servo motor (23), and the second arm (24) and the second material suction / detachment means (25) are raised according to the loading height.By the reverse rotation of the second servo motor (20), the second transport unit (19), the second arm (24), and the second material suction / desorption means (25) move backward (F direction), and by the reverse rotation of the drive motor (5), the turntable (7) of the turntable (6) rotates 180° counterclockwise (A direction) and waits to take out the next molding material (S) near the front process mold (M1), and the first material suction / desorption means (18) that is absorbing the molding material (S) of the front process mold (M1) rotates 180° counterclockwise (A direction) by the reverse rotation of the drive motor (5) and waits to bring in the material (S) near the rear process mold (M2).

[0104] While the upper mold is lowered and the material (S) of the front process mold (M1) and the post-process mold (M2) is being punch-molded, the first material suction / detachment means (18) takes out the molding material (S) of the front process mold (M1) and then rotates 180° toward the post-process mold (M2) to wait for the material (S) to be brought in. At the same time, the first material suction / detachment means (18) rotates 180° by the drive motor (5) to wait for the material (S) of the front process mold (M1) being molded to be taken out.

[0105] When the material (S) of the front process mold (M1) and the material (S) of the post-process mold (M2) are formed by punching molding of the upper mold, the material (S) is brought in, taken out, and transported through the above process.

[0106] In the present invention, by configuring or controlling the first and second material adsorption / desorption means (18) (25) to rotate and / or pivot by reducing the radius of rotation when the first and second material adsorption / desorption means (18) (25) rotate by the turntable (6), not only is the centrifugal force (or rotational inertia) greatly reduced to achieve stable rotation, but also the feed speed can be increased, thereby improving the overall productivity of the press.

[0107] In the present invention, the material (S) is simultaneously fed in and fed out by the first and second material suction and discharge means (18) (25) installed as a pair on the left and right and performing a positive and negative rotational movement and a linear reciprocating movement, thereby maximizing the material (S) transfer efficiency and greatly improving press productivity.

[0108] In the present invention, the first arm (17) and the second arm (24) maintain a separation distance (L1) of 10 to 500 mm, so that they do not come into contact with or interfere with each other when moving up and down and forward and backward (or left and right) to load, load, and transport the material (S).

[0109] The present invention is provided with first and second transport units (12) (19) and first and second lifting units (15) (22) that move in both directions on a rotating plate (7) that rotates forward and backward by a driving motor (5) to transport a material (S), first and second arms (17) (24), and first and second material suction and removal means (18) (25), so that the material (S) can be rotated and transported along the shortest possible movement path to be loaded, unloaded, and transported to and from a front process mold (M1), thereby maximizing material transport efficiency.

[0110] In the present invention, since the turntable (6) is firmly supported by a ring bearing that also serves as a shaft member, installation of the turntable (6) is easy without the need for a separate rotation axis, and even if the center of gravity changes significantly due to the transport of the material (S), the turntable (6) is supported horizontally, so not only is sagging or vibration prevented, but smooth rotational movement is achieved.

[0111] The turntable (6) of the present invention is stably supported by the inner ring (34) and the outer fixing ring (32), so that the phenomenon of control precision deteriorating due to vibration, clearance, left-right vibration, etc. is prevented, and the service life is greatly extended, and maintenance costs are also greatly reduced.

[0112] The unexplained symbol 50 is a cable tie.

[0113] The present invention described above is not limited to the present embodiment and the attached drawings, and various substitutions, modifications, and changes are possible within the scope that does not depart from the technical spirit of the present invention, which will be apparent to those skilled in the art to which the present invention pertains.
