It is axially supported by (234) (237). The motor 24 may be fixed to the shaft support 252, and the rotation shaft 241 to which the helical gear 242 is fixed passes through the hole 255 of the shaft support 252. The helical gears 242 and 251 are protected by a case 253.

In the present invention, when the material 19 is adsorbed by the material adsorption and desorption means 20 as described above, the transfer table 10 moves to the destination (for example, a press mold in a subsequent process), and the material 19 ) Is rotated in consideration of the carry-in angle (after tilting) and then carried or transferred to the press mold of the subsequent process, so that the transfer time of the entire material 19 is shortened and productivity is further improved.

14 is a plan view showing an operation state showing a process of transferring the material 19 located in the mold M1 in the left direction (E) to the mold M2 in the right direction (G) in the present invention, the turntable 6 The rotation radius of the material adsorption and desorption means (20) is required around the shaft member (5), but a horizontal guide unit (9) is installed on the upper surface of the turntable (6) so that the rotational movement by the turntable (6) and The horizontal guide unit 9 allows the linear motion to be performed together, but with the help of the turntable 6 and the horizontal guide unit 9 as shown in Figs. 5 and 14, the material adsorption and desorption means 20 is moved to the left (E). When moving above the mold (M1) of the material, the material adsorption and desorption means (20) descends by the vertical guide unit (13) to adsorb and take out the molding material (19) on the mold (M1), and the material detector (21) moves the material ( When the adsorption of 19) is sensed, the material adsorption and desorption means 20 rises to a predetermined height under the control of the controller, and the turntable 6 rotates counterclockwise (A direction), and transfer installed in the horizontal guide unit 9 The table 10 moves in the D direction (reverse direction).

Accordingly, as shown in Fig. 6, the material adsorption and desorption means 20 and the material 19a are retracted to the maximum in the front part of the press material transfer system 1, and then the turntable 6 is in a counterclockwise direction (A in Fig. 14). Direction), the transfer table 10, which has moved backward at maximum, moves in the C direction, and thus, the material adsorption and desorption means 20 is maximum in the C direction (forward direction) as shown in FIGS. 7 and 14. As it protrudes forward, it stops on the mold (M2) located in the right direction (G), and the material adsorption and desorption means (20) descends by the vertical guide unit (13) to transfer the molding material (19a) onto the mold (M2). When carrying in and detaching, the material adsorption and desorption means 20 rises to a predetermined height under the control of the controller and returns to the reverse order to complete one transfer of the material 19, and the material 19 is automatically transferred by repeating this process. This is achieved.

That is, when the material adsorption and desorption means 20, which has delivered the material 19, rises to a predetermined height by the vertical guide unit 13, the turntable 6 rotates in a clockwise direction (B direction) under the control of the controller, and the horizontal The transfer table 10 installed on the guide unit 9 moves backward in the D direction.

Accordingly, as shown in FIG. 6, the material adsorption and desorption means 20 moves backward at the front part of the press material transfer system 1 to the maximum, and then the turntable 6 continues to rotate in the clockwise direction (B direction) and the maximum The transfer table 10, which has been moved backward, moves forward in the C direction, and thus the material adsorption and desorption means 20 protrudes to the maximum as shown in Figs. 5 and 14, and the mold M1 located in the left direction (E). ) It waits to adsorb the next transfer material above.

The waiting time (period) of the material adsorption and desorption means 20 may be a period in which the upper mold rises to a predetermined height after completing the molding (punching) of the material 19 on the mold M1.

In FIG. 14, since the material adsorption and desorption means 20 is immersed while maximally moving backward (L1) from the front part of the press material transfer system 1, there is an extra distance (L2) space in the front part of the press material transfer system (1). Worker space) is created, so not only the working space is reduced, but also the rotational movement by the turntable 6 and the linear movement by the horizontal guide unit 9 are simultaneously implemented between the material transfer. As carry-in/out is achieved, material transfer efficiency is maximized and inertia is greatly reduced.

In addition, the ball plunger 27 installed in plural on the upper surface of the plate 4 is installed so that a ball bearing 27a is rolled, and the ball bearing 27a is formed of a ring member 28 fixed to the turntable 6. Since the turntable 6 is stably supported while in point contact with the bottom surface, the transfer table 10 moves in a state where the material 19 is adsorbed, or the center of gravity is on one side or the other side while returning after transferring the material 19. Even if it is focused on the side, smooth operation and stable forward and reverse rotation of the turntable 6 are achieved, and vibration and noise are drastically reduced.

The motors 7, 11, 15, 15a, 24, and 46 are servo motors that are precisely controlled with an encoder built in, and are precisely controlled by inputting an operation signal or a moving distance or rotation angle to a controller.

The press material transfer system 1 of the present invention is installed between the mold M1 and the mold M2 of the press to carry out and transport the flat material or the material 19 molded by the mold M1, and then the mold for the subsequent process. By bringing it into (M2) and making it possible to mold, the automation and high-speed transfer of the material (19) is achieved, and it can be easily installed and used not only in new facilities for mass production, but also in many existing press facilities for small-scale production of multiple products. There will be.

In the present invention, for convenience of explanation, two right and left molds M1 and M2 are shown and given an example, but of course, a continuous press operation is performed by installing the present invention between a plurality of presses exceeding two depending on the number of processes. It is configured to lose.

The mold M1 may be a material supply unit in which a plurality of materials 19 are stacked.

19 to 29 of the present invention constitute a safety means 260 that physically or mechanically prevents the material adsorption and desorption means 20 from protruding to the front (front) of the press material transfer system 1 Various safety accidents are prevented by protecting the worker (H) located in the front direction (F) of the transfer system (1).

The safety means 260 is fixed to one side or the bottom surface of the transfer table 10, or is fixed to the extension block 261 fixed to the transfer table 10, and clicks 262 of a predetermined length parallel to the LM rail 71. ) And, the LM rail 71 is installed on the side of the fixing member 711 to which the LM rail 71 is fixed and rises vertically and is caught by the click 262 to stop the transfer table 10 or descend vertically to the click ( The ratchet 264 of the locking means 263 which is disengaged from (during apart from) and is released from the 262, permits the reciprocating movement of the transfer table 10, and the ratchet 264 descends by the magnetic force of the permanent magnet. It includes an attraction member (265) to help (help) so as to.

The click 262 is a serrated shape having a plurality of inclined portions 266, a plurality of vertical portions 267, and a vertical triangular locking groove 268 formed between the inclined portions 266 and the vertical portions 267, , When the ratchet 264 located at the top of the locking means 263 rises and is caught in the locking groove 268, or the ratchet 264 descends to a predetermined height h2 and leaves the locking groove 268 It is configured to release the jam.

Therefore, when the ratchet 264 descends and leaves the locking groove 268, the transfer table 10, the vertical guide unit 13, and the material adsorption and desorption means 20 are reciprocated in sections, and the material 19 is transferred. It is achieved, and when the ratchet 264 rises and is caught in the locking groove 268, the forward movement of the click 262 is suppressed, and the transfer table 10 and the vertical guide unit 13 and the material adsorption/detachment means 20 The advancement of is also suppressed. That is, when the material adsorption and desorption means 20 faces the front (front) where the worker is located, the material adsorption and desorption means 20 is prevented from moving or protruding in the worker (H) direction (F direction) as shown in FIG. Therefore, the worker (H) is protected, and accordingly, the worker (H) can work with confidence.

The locking means 263 is fixed to the side of the fixing member 711 to which the LM rail 71 is fixed so that the transfer table 10 reciprocating on the LM rail 71 can be stopped.

24 is a perspective view of the locking means 263, a bracket 270 fastened and fixed to the side of the fixing member 711 by a fastening member, a protrusion 271 extending to the front of the bracket 270, and a protrusion ( 271, a guide pipe 273 fitted and fixed in a through hole 272 formed perpendicular to the guide pipe 273, a lifting rod 274 slidably coupled to the guide pipe 273, and a lifting rod installed on the upper surface of the protrusion 271 A support member 275 for supporting 274, and a ratchet portion 276 and a stepped portion having a diameter slightly larger than that of the lifting rod 274 and formed at the upper end of the lifting rod 274, for example, 2 to 10 mm in diameter. 277, a spring housing 278 that is coupled to the outer periphery of the lifting rod 274 and then engages with the stepped portion 277 and opens downward, and is elastically installed in the spring chamber 279 inside the spring housing 278 and is ratcheted. A spring 280 that raises the portion 276, a ratchet 264 formed on the upper end of the ratchet portion 276 and coupled to and spaced apart from the locking groove 268, and an inclined surface formed on one side of the ratchet portion 276 (283), a flat portion 284 formed in the longitudinal direction of the other side of the ratchet portion 276, a vertical member 269 fixed to the upper surface of the bracket 270, and horizontally installed on the vertical member 269 And a horizontal bar 285 that prevents rotation while allowing the ratchet part 276 to move up and down while being in point contact with the flat part 284, and a magnet housing 286 that is fastened and fixed to the lower end of the lifting bar 274 and opened downward. , A permanent magnet 287 installed inside the magnet housing 286, and an arc-shaped attraction member 265 that is installed back and forth on the upper surface of the plate 4 and pulls the permanent magnet 287 to lower the ratchet 264. ). The inclined portion 266 and the inclined surface 283 are inclined toward the stopper 9a as they go downward.

The guide tube 273 may be a sliding bearing.

The attraction members 265 and 265a are composed of a pair of left and right ferrous metals so that magnetic force is applied, and a circular (circular) motion section of the permanent magnet 287 so that the permanent magnet 287 can be pulled as shown in FIG. 22 The plate 4 is of an arc shape installed on the upper surface with a predetermined width (W), a predetermined height (h1), and a predetermined angle (θ2).

The attractive members 265 and 265a have a plurality of fastening holes 291 formed at predetermined intervals as shown in FIG. 24, and the fastening members are inserted into the fastening holes 291 and then fastened to the upper surface of the plate 4. It will be fixed.

The safety means 260 of the present invention is a permanent magnet 287 that rotates forward or backward along the transfer table 10, and in the engaging angle (θ1) section where the attraction members 265 and 265a are not located, as shown in FIG. 27 Likewise, since a considerable height (h3) is generated between the plate 4 and the permanent magnet 287, the attraction force for the permanent magnet 287 to descend does not act, so the ratchet 264 raised by the elastic force of the spring 280 As it enters and is caught in the locking groove 268, the advance (moving in the C direction) of the transfer table 10 is prevented, and the advancement of the material adsorption and desorption means 20 is also prevented. ) Is protected.

In addition, the permanent magnet 287 rotating forward or reverse along the transfer table 10 is the attractive member by the magnetic force of the permanent magnet 287 in the section of the locking release angle (θ2) where the attractive members 265 and 265a are located. Since the permanent magnet 287 descends in the direction of (265) (265a), the ratchet 264 raised by the spring 280 as shown in FIG. 26 descends to a predetermined height (h2) and is caught out of the locking groove 268 Since this is released, the transfer table 10 can be moved forward and backward (C direction and D direction), and the material adsorption and desorption means 20 adsorbing the material 19 are provided with the vertical guide unit 13 and the horizontal guide unit 9 ) And/or the material 19 is carried in and out with the help of the tilting means 250.

In the present invention, even if the advancement of the transfer table 10 is prevented by the safety means 260, the driving force is transmitted to the transfer table 10 by the operation of the motor 46, but the controller recognizes it as an overload of the motor 46 and By stopping 46, the transfer table 10 is stopped, and failure or damage of the motor 46 is prevented.

In the present invention, the horizontal bar 285 in contact with the planar portion 284 of the ratchet portion 276 minimizes friction due to point contact, and allows the ratchet portion 276 to move up and down while inhibiting rotation.

25 is a perspective view of another embodiment of the attractive members 265 and 265a, in which a plurality of concave grooves are formed at predetermined intervals on an upper surface of one side of the attractive members 265 and 265a, and the first, 2 and 3 permanent magnets 288, 289, and 290 are embedded and installed so that the magnetic force is transmitted to the upper portion of the attractive members 265 and 265a.

The concave groove is of an upwardly open type so that the first, second, and third permanent magnets 288, 289, and 290 can be exposed to the upper surfaces of the attractive members 265 and 265a.

In the above, when the bottom surface of the permanent magnet 287 is S-pole as shown in FIG. 28, the upper surface of the first permanent magnet 288 is composed of S-pole so that repulsive force is generated so that the upper surface of the first permanent magnet 288 is The permanent magnet 287 and the ratchet 264 are raised and caught, and the upper surfaces of the second and third permanent magnets 289 and 290 are configured as N poles as shown in FIG. 29 to generate attractive force. , 3 On the upper surface of the permanent magnets 289 and 290, the permanent magnet 287 and the ratchet 264 are lowered so that the latching of the ratchet 264 is released, thereby achieving more effective locking and unlocking.

That is, when the upper portion of the horizontal guide unit 9 is completely rotated counterclockwise (in the direction A), the permanent magnet 287 is positioned within the locking release angle θ2, so that the magnetic force is generated by the adjacent attraction member 265a. As the permanent magnet 287 descends and the ratchet 264 descends to a predetermined height (h2), the jam is released, and the transfer table 10 and the material adsorption and desorption means 20 advance in the forward direction (C direction). Then, the material 19 in the left direction (E direction) is adsorbed, and then the transfer table 10 and the material adsorption and desorption means 20 are moved backward (D direction), and at the same time, horizontal guidance by the turntable 6 The unit 9 rotates in the clockwise direction (B direction), passes the second and third permanent magnets 289 and 290 of the N pole, and passes the first permanent magnet 288 of the S pole as shown in FIG. Is generated. At this time, since the first permanent magnet 288 is fixed, the permanent magnet 287 and the ratchet 264 rise to a predetermined height h2 and quickly enter the locking groove 268 and are locked. C direction movement) is prevented, the advance of the material adsorption and desorption means 20 is also prevented, and the spring 280 until the permanent magnet 287 rotating clockwise by the turntable 6 goes out of the latch release angle θ2. ) By the elasticity (elasticity) of the ratchet 264 is continuously maintained, so that the transfer table 10 and the material adsorption and desorption means 20 are prevented from advancing or transferring in the front direction (F direction). Likewise, the worker (H) working in the front direction (F direction) is protected, and the attraction member 265a that meets after the permanent magnet 287, which has been continuously rotating clockwise by the turntable 6, enters the locking angle θ1. ) As strong attraction is generated by the second and third permanent magnets 289 and 290 of the N pole, the permanent magnet 287 and the ratchet 264 quickly descend to a predetermined height (h2), and the jam is released and the transfer table (10) and the material adsorption and desorption means 20 advance in the forward direction (C direction), so the material 19 is transferred in the right direction (G), and then the material 19 is transferred to the press mold (M2) in the subsequent process. Bring in and return.

In the above, when the permanent magnet 287 enters the locking angle (θ1) section, a rapid locking of the ratchet 264 is achieved by the strong repulsive force of the permanent magnet 287 and the first permanent magnet 288, and the permanent magnet ( When 287 enters the section of the latch release angle θ2, the latching state of the ratchet 264 is quickly released by the strong attraction of the permanent magnet 287 and the second and third permanent magnets 289 and 290.

In the present invention, the transfer table 10 and the material adsorption and desorption means 20 for transferring the material 19 to the rear end move from the left direction (E) to the right direction (G), but in the front direction (F), FIG. 14, As shown in Fig. 22, the transfer table 10, the material adsorption and desorption means 20, and the material 19 move backward (d direction), and then move to the right direction (G) by the turntable 6, and the locking angle ( When entering the θ2) section, the latching of the ratchet 264 is released, so the transfer table 10, the material adsorption and desorption means 20, and the material 19 advance (C direction) to press the material 19 at the rear end. It is transferred to the mold (M2) of and then returned.

On the other hand, even if a multi-stage safety device by the proximity sensor 98, 99, etc. is provided, there is a problem that a safety accident occurs when the co-worker operates in the direction of the worker (H) due to a mistake or malfunction of a co-worker. Even if the transfer table 10 advances in the front direction (F direction) due to a mistake or malfunction, it is mechanically (physically) stopped by the safety means 260, which is a physical (mechanical) safety device.

That is, when the transfer table 10 rotated by the turntable 6 is located in the section of the locking release angle θ2, the ratchet 264 rising by the spring 280 enters the locking groove 268 and is locked. Since the movement of the transfer table 10 and the material adsorption and desorption means 20 is physically stopped and the movement of the transfer table 10 and the material adsorption and desorption means 20 in the front direction (F direction) where the worker H is located, the worker H located in the front is mainly protected.

On the other hand, the biggest structural disadvantage of the conventional shuttle robot or single-acting robot, which is used intermittently in the conventional press workshop, is that the trajectory and motion are fixed, so the height alignment of the mold located in the press during the installation and production process of the robot, and the work center Line alignment is essential and structural changes according to process changes are not allowed. However, in the present invention, it is possible to adjust the height of each device and device, and to adjust the front, rear, left and right positions, so that the mold height alignment of the press machine and the work center line are possible. Alignment is unnecessary, mass production of a single product, production of small quantities and multiple products, can be easily applied to various installation conditions and use environments, easy to install, convenient to expand and change, and have the advantage of low manufacturing cost compared to multifunctional .

In addition, the present invention not only can easily change the supply and delivery direction of the material from left to right or from right to left according to the working situation of the production site, but also the material being transferred 19 is rotated and linearly transferred, and the arm ( 14) by using the motor 24 and the power transmission means to rotate the rotating rod 23 inside the rotating rod 23 in a forward and reverse direction, the material 19 being transferred can be rotated and reversed at a predetermined angle, so it can be transferred quickly to the working environment without additional equipment. You will be able to respond.

In addition, the present invention is designed in a modular structure that can be easily modified and reused according to the installation environment when changing or relocating production facilities at the press production site, so it has many advantages such as productivity improvement, labor cost reduction, facility investment, and cost reduction. And, due to the automation and convenience of use, it can be widely used at low cost in the press industry-related processing production process.

In addition, in the present invention, the material adsorption and desorption means 20 for transferring and adsorbing and desorbing the material 19 is a rotational motion by a turntable and a linear motion by a horizontal guide unit 9 and a vertical guide unit 13. As the lifting movement is implemented, the material 19 is transferred and carried in/out of the moving line of the shortest distance, so that the material 19 transfer efficiency is maximized, and vibration, noise, and inertia are greatly reduced.

The present invention described above is not limited to the present embodiment and the accompanying drawings, and various substitutions, modifications and changes are possible within the scope of the technical spirit of the present invention, which is in the technical field to which the present invention pertains.
