Description

Technical Field

[0001] The invention belongs to the technical field of coil material processing, and in particular relates to an automatic coil material transporting and feeding device and a process method thereof. Background Art

[0002] With the continuous improvement of the degree of automation in the power industry, equipment such as storage, transportation and automatic loading of coils has been widely used.

[0003] Currently, the automatic transfer of coil materials on the market mostly adopts the V-shaped mother pallet method, that is, the coil materials are stored on the V-shaped mother pallet, and then the V-shaped mother pallet is picked up by a manual forklift to transfer the coil materials. This transfer method is not only inefficient, but also causes the return transfer process of the V-shaped mother pallet, adding unnecessary workload.

[0004] In addition, there is a cantilevered coil transfer and loading method on the market. This method uses a cantilevered inner ring of the coil to transfer the coil. Although the V-shaped mother pallet is omitted, there are certain requirements for the inner diameter of the coil. It is only suitable for coils with a larger inner diameter, and the inner hole of the cantilevered coil is shared with the workshop processing equipment during transfer, that is, the transfer equipment cannot be directly connected to the workshop processing equipment, and a set of transfer equipment needs to be added between the two. For example, for the transfer of silicon steel coils and the loading of workshop cross-cutting equipment, the inner diameter of the silicon steel coil is first cantilevered by the transfer equipment and transported to the cross-cutting equipment, and then the silicon steel coil is placed on the transfer equipment. The transfer equipment lifts the outer diameter of the silicon steel coil and lifts the silicon steel coil onto the cross-cutting equipment. The cross-cutting equipment is fixed through the inner hole of the silicon steel coil. This not only increases the equipment cost, but also complicates the process, increases the transfer time and risk of the coil, and has low production efficiency, and cannot better meet the needs of automated production of coils.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1

[0029] like Figure 1-7 As shown, the automatic coil material transfer and loading equipment includes: a horizontal moving mechanism, a rotating mechanism and a lifting and dragging mechanism.

[0030] The horizontal moving mechanism can realize the horizontal movement of the rotating mechanism and the lifting and dragging mechanism, and includes a base frame 26. The base frame 26 is the main body of the horizontal moving mechanism. The base frame 26 is a rectangular frame structure welded by rectangular tubes and plates, including two cross beams in the width direction and three cross beams in the length direction and a number of reinforcing ribs. The base frame 26 is fixedly installed on the ground by anchor bolts to ensure the stability of the equipment during operation. The base frame 26 is arranged between the fixed material taking end and the workshop processing equipment. The length of the base frame 26 adapts to the distance between the fixed material taking end and the workshop processing equipment, forming a fixed position of the coil 19 transfer and loading station. The base frame 26 is respectively provided with height adjustment seats 17 on both sides of one end facing the fixed material taking end. The height adjustment seat 17 is removable. The height adjustment of the end of the base frame 26 can be achieved by processing adjustment holes of different heights on the base frame 26, and adjusting bolts and the height adjustment seat 17 are used to adjust the height of the end of the base frame 26. For some specific projects, the ground of the fixed material taking end is lower. By setting the height adjustment seat 17, it can adapt to the ground conditions of various project occasions, so that the use range of the equipment is wider. A plurality of hoisting holes 8 are provided on the outer peripheral frame of the base frame 26 , and the hoisting holes 8 can facilitate hoisting and carrying the base frame 26 .

[0031] The upper surface of the longitudinal beams on both sides of the chassis 26 is fixed with a first slide rail 7 by bolts, and the side of the longitudinal beam in the middle of the chassis 26 is fixed with a bevel rack 9 by bolts. The bevel rack 9 is set in the middle of the three longitudinal beams. When the driving force is applied, the bevel rack 9 is centered and it is not easy to produce a driving dead point. A horizontal drag chain assembly 6 is set on the outer side of the longitudinal direction of the chassis 26. The horizontal drag chain assembly 6 is used to place wire bodies such as power cables and signal transmission lines. The wire body is the connection between signal transmission and equipment power supply. Generally, the wire body in the moving position cannot be directly exposed and must be placed in the drag chain. The horizontal drag chain assembly 6 includes a horizontal drag chain support seat and a horizontal drag chain. The horizontal drag chain support seat is welded to the outer side of the longitudinal direction of the chassis 26, and the horizontal drag chain is placed on the horizontal drag chain support seat; one end of the horizontal drag chain is fixedly connected to the horizontal drag chain support seat, and finally electrically connected to the control end, and the other end of the horizontal drag chain is fixedly connected to the horizontal moving trolley 18, and finally electrically connected to the servo motor 37, the reducer 38 and the rotary power cylinder 1.

[0032] The horizontally movable trolley 18 is a rectangular frame structure welded by channel steel and plate materials. First sliders 35 are provided at the four corners of the bottom surface of the horizontally movable trolley 18. The first slider 35 is fixedly connected to the horizontally movable trolley 18 by bolts. A first slide groove is provided below the first slider 35. The first slide groove cooperates with the first slide rails 7 on both sides of the base frame 26, so that the horizontally movable trolley 18 can move stably horizontally along the length direction of the base frame 26. A reducer mounting seat 39 is fixedly provided on the inner side in the width direction (the side away from the fixed material-retrieving end) of the horizontal movable carriage 18. The position of the reducer mounting seat 39 corresponds to the position of the bevel rack 9. The reducer 38 is fixedly mounted on the reducer mounting seat 39. The reducer 38 is fixedly connected to the servo motor 37 on the top. The output shaft of the reducer 38 faces downward. A bevel gear 34 is mounted on the output shaft of the reducer 38. The bevel gear 34 is meshed and connected with the bevel rack 9 on one side of the longitudinal beam. The servo motor 37 rotates, and the bevel gear 34 is driven to rotate through the reducer 38. The meshing action of the bevel gear 34 and the bevel rack 9 drives the horizontal movable carriage 18 to move horizontally along the first slide rail 7. The meshing drive strength of the bevel gear 34 and the bevel rack 9 is higher, which can increase the bearing capacity and life of the gear rack.

[0033] The rotating mechanism can realize the rotation of the turning frame 2 at two angles of 45° and 90°, so as to support the lifting and dragging mechanism for safe and stable transportation, material picking and loading. The rotating mechanism includes a rotating power cylinder 1 and a turning frame 2. The turning frame 2 is a frame welded by a plurality of square tubes. The square tubes on both sides of the upper end of the frame are extended to provide space for the loading of the coil 19; a cross-shaped crossbeam is welded in the middle of the frame to improve the mechanical strength of the turning frame 2. Hinge seats 27 are welded at both ends of the lower side of the turning frame 2. The hinge seat 27 is rotatably connected to the rotating support seat 16 through the hinge seat pin shaft. The rotating support seat 16 is fixedly installed on the upper side of the horizontal moving trolley 18 near the fixed material picking end by strong bolts. The turning frame 2 can rotate around the hinge seat pin shaft.

[0034] The first connecting seat 14 is fixedly installed on the middle position in the width direction of the horizontal moving trolley 18 away from the fixed material-feeding end. The installation position of the first connecting seat 14 avoids the servo motor 37. The rotating power cylinder 1 is rotatably installed on the top of the first connecting seat 14 through the first pin shaft. The piston rod of the rotating power cylinder 1 is fixedly connected to the center of the cross-shaped beam of the turning frame 2 to provide power for the rotation of the turning frame 2.

[0035] A horizontal first support plate 23 is provided on the front side of the lower end of the left and right side frames of the turning frame 2 (the side close to the fixed material taking end). The position of the first support plate 23 does not affect the connection between the hinge seat 27 and the rotating support seat 16. A vertical support screw 24 corresponding to the first support plate 23 is fixedly provided above the rotating support seat 16. When the turning frame 2 rotates to 90°, the lower surface of the first support plate 23 abuts against the upper surface of the support screw 24, providing auxiliary support force for the 90-degree turning frame 2 to ensure the stability of the equipment operation. The height of the support screw 24 can be adjusted according to the position of the first support plate 23.

[0036] The hinge seat 27 is provided with an extension section on one side of the outer side of the flip frame 2. The extension section of the hinge seat 27 is parallel to the side of the flip frame 2 and the widths of the two are matched and kept consistent. An arc-shaped in-place detection plate 30 is fixedly installed on the outer side of the extension section of the hinge seat 27 on one side. The lower part of the arc-shaped in-place detection plate 30 is fixed to the horizontal moving trolley 18 by bolts. An arc-shaped through hole is opened on the upper end of the arc-shaped in-place detection plate 30. The two ends of the arc-shaped through hole are respectively fixedly installed with a first photoelectric proximity switch 28 and a second photoelectric proximity switch 29. The first photoelectric proximity switch 28 is located directly above the hinge seat pin shaft and is used to detect the 90° in-place signal of the flip frame 2. The second photoelectric proximity switch 29 is at a 45-degree angle relative to the hinge seat pin shaft and is used to detect the 45° in-place signal of the flip frame 2. The extended section of the hinge seat 27 can shorten the distance between the side of the flip frame 2 and the arc-shaped in-position detection plate 30. The extended section of the hinge seat 27 cooperates with the photoelectric proximity switch on the arc-shaped in-position detection plate 30 to provide a stable rotation in-position detection signal for the flip frame 2. When the side of the extended section of the hinge seat 27 is flush with the photoelectric proximity switch, the photoelectric proximity switch provides a rotation in-position detection signal to the control end, thereby controlling the action of the rotary power cylinder 1.

[0037] An inclined support frame 5 is respectively arranged above the two corners of the horizontal moving trolley 18 on the same side as the rotary power cylinder 1. The upper end of the inclined support frame 5 is inclined toward the turning frame 2. The inclined support frame 5 is welded with steel plates. When the turning frame 2 rotates 45°, it just contacts the inclined support frame 5, playing a supporting role to ensure the stability and safety of material transportation. A second support plate 3 is welded at the matching position of the turning frame 2 and the inclined support frame 5. The second support plate 3 increases the support area and makes the support more stable.

[0038] The lifting and dragging mechanism is used for forking the coil 19 and safely transporting it. It can be docked with the workshop processing equipment to realize unmanned and automatic loading. The lifting and dragging mechanism includes a lifting power cylinder 25, which is fixedly installed on the other side of the turning frame 2 opposite to the rotating power cylinder 1, close to the fixed material picking end. A second connecting seat 22 is fixedly installed in the middle position of the horizontal square tube at the lower end of the frame of the turning frame 2. The lifting power cylinder 25 is fixedly installed on the second connecting seat 22 through a second pin shaft. The top end of the piston rod of the lifting power cylinder 25 is fixedly connected to the forking and lifting mechanism 12. The forking and lifting mechanism 12 is used for supporting, transporting and loading the coil 19. When the turning frame 2 is 90 degrees and forks the coil 19, the first support plate 23 cooperates with the support screw 24 to share the pressure of the lifting power cylinder 25.

[0039] The fork material and lifting mechanism 12 includes a lifting installation plate 43, and the two ends of the side of the lifting installation plate 43 away from the fixed material-feeding end are respectively provided with a vertical slider bottom plate 45, and a plurality of vertical second sliders 13 are fixedly installed on the slider bottom plate 45. The slider bottom plate 45 makes the installation of the second slider 13 more stable. The present embodiment adopts four second sliders 13, which are arranged in pairs opposite to each other. The two second sliders 13 on the same side must ensure their parallelism and concentricity, and are fixedly connected to the lifting installation plate 43 by bolts; the two sides of the turning frame 2 facing the front side (close to the fixed material-feeding end) are provided with vertical second slide rails 21, and the second slide groove is provided on the second slide slide 13. The second slide rail 21 cooperates with the second slide groove of the second slide slide 13, and is powered by the lifting power cylinder 25, so as to realize the up and down sliding of the fork material and lifting mechanism 12 relative to the turning frame 2.

[0040] The fork support plate 40 is welded to the front side of the lifting installation plate 43 (the side away from the second slider 13). The fork support plate 40 is hollowed out in the length direction to form five gaps in the width direction. Two adjacent gap sides form three groups of forks in pairs, which can hold three coils 19 at a time. L-shaped reinforcement ribs 20 are welded between the lower surface of the gap side of the fork support plate 40 and the lifting installation plate 43. The L-shaped reinforcement ribs 20 increase the support strength of the fork support plate 40. In each group of forks, the inner edge of the paired gap side is processed into an inclined surface, the angle of the inclined surface matches the outer diameter of the coil 19, and the inclined surface makes the coil 19 more stable on the fork. In each set of forks, a pair of coil limit blocks 11 are arranged at the front end of the notch side. The inner edge of the pair of coil limit blocks 11 is processed into an arc surface. The angle of the arc surface matches the outer diameter of the coil 19. The arc surface is provided with an arc groove. The arc groove fits the arc of the outer edge of the inner hub of the coil 19 on both sides to prevent the coil 19 from rolling sideways and sliding back and forth. The pair of coil limit blocks 11 fork and clamp the two sides of the coil 19, so that the coil 19 is not easy to roll down. When taking materials, the entire coil limit block 11 will be under the coil 19, lifting the material from below; the same is true when loading materials. After loading, the fork material and the lifting mechanism 12 drive the coil limit block 11 to descend first, and then the fork is horizontally retracted through the horizontal moving mechanism.

[0041] A vertical rear baffle 41 is fixedly arranged on one side of the fork support plate 40 near the lifting installation plate 43. An arc groove is provided on the top of the rear baffle 41 facing the center line of each set of forks, leaving space for the inner hole of the coil 19 to cooperate with the fixed axis of the workshop processing equipment. A third photoelectric proximity switch 10 is arranged on the rear baffle 41 below the center of the arc groove. The third photoelectric proximity switch 10 is used to detect whether the coil 19 is in place and whether there is cargo on the fork, so as to avoid picking up the material when there is cargo. A rubber pad 36 is fixedly arranged on the front side of the rear baffle 41. The rubber pad 36 is arranged in pairs on the rear baffle 41 on both sides of the arc groove, which plays a role in preventing collision and shock absorption for the forked coil 19; a countersunk hole is provided on the rubber pad 36, and the rubber pad 36 is fixedly connected to the rear baffle 41 by a countersunk bolt; the rubber pad 36 has a certain thickness, and the thickness of the rubber pad 36 is greater than the height of the third photoelectric proximity switch 10 protruding, so as to ensure that the material will not collide with the third photoelectric proximity switch 10.

[0042] A certain gap is left between the rear baffle 41 and the lifting installation plate 43 to facilitate material removal and loading; a number of square support plates 42 are evenly arranged in the reserved gap, and the square support plates 42 can strengthen the structural strength of the rear baffle 41. The square support plates 42 are provided with threading holes 44, which are used to place the connecting wires for signal transmission and equipment power supply, and cooperate with the vertical drag chain assembly 4. A number of lifting holes 8 are opened on the rear baffle 41 and the lifting installation plate 43.

[0043] The vertical lifting detection plate 31 is fixedly installed on the outer side of the slider bottom plate 45 at one end of the lifting installation plate 43 by screws. The lifting detection plate 31 is perpendicularly intersected with the lifting installation plate 43, and the lifting detection plate 31 is an opaque plate. The second slot-shaped photoelectric switch 32 and the first slot-shaped photoelectric switch 33 are fixedly installed on the side of the flip frame 2 on the same side as the lifting detection plate 31. The first slot-shaped photoelectric switch 33 is located below the second slot-shaped photoelectric switch 32. The lifting detection plate 31 cooperates with the second slot-shaped photoelectric switch 32 and the first slot-shaped photoelectric switch 33 to detect whether the fork material and lifting mechanism 12 is lifted and lowered.

[0044] The vertical drag chain assembly 4 is fixedly installed on the turning frame 2 in the vertical direction. The vertical drag chain assembly 4 includes a vertical drag chain support seat and a vertical drag chain.

Embodiment 2

[0047] The method for automatic coil material transfer and loading is based on the automatic coil material transfer and loading equipment described in the first embodiment, and comprises the following steps:

[0048] Step 1: Press the equipment start button, the third photoelectric proximity switch 10 determines whether there is cargo on the fork, and sends a first signal to the control end (indicating whether there is cargo on the fork or not);

[0049] The control end receives the first signal. If the first signal indicates that there is no cargo on the fork, the control end controls the servo motor 37 to start forward rotation, and moves the horizontal movable trolley 18 toward the fixed material-collecting end through the meshing of the bevel gear 34 and the bevel rack 9; if the first signal indicates that there is cargo on the fork, execute step 9.

[0050] Step 2, when the servo motor 37 rotates forward to reach the first set position, the servo motor 37 feeds back a second signal (indicating that the servo motor 37 rotates forward for the first time, that is, the horizontal moving trolley 18 moves to a position close to the coil 19) to the control end, and the control end receives the second signal and controls the rotation of the power cylinder 1 to move, and the servo motor 37 stops operating.

[0051] Step 3, the piston rod of the rotating power cylinder 1 begins to extend until the flip frame 2 rotates from 45 degrees to 90 degrees. The first photoelectric proximity switch 28 on the arc-shaped in-position detection plate 30 detects the third signal (indicating that the flip frame 2 rotates from 45 degrees to 90 degrees) and feeds it back to the control end. The control end controls the rotating power cylinder 1 to stop working and keep it in a pressure-maintaining state. At the same time, the control end controls the lifting power cylinder 25 to move.

[0052] Step 4, the lifting power cylinder 25 is activated. At this time, the fork and lifting mechanism 12 is located at the bottom of the second slide rail 21, and the piston rod of the lifting power cylinder 25 begins to extend. When the lifting detection plate 31 on the fork and lifting mechanism 12 reaches the position of the first slot-shaped photoelectric switch 33, the first slot-shaped photoelectric switch 33 sends a fourth signal to the control end (indicating that the fork support plate 40 of the fork and lifting mechanism 12 has reached the material picking height). After receiving the fourth signal, the control end controls the lifting power cylinder 25 to stop and maintain pressure, and controls the servo motor 37 to rotate forward.

[0053] Step 5, the servo motor 37 rotates forward to move the horizontal movable trolley 18 toward the fixed material picking end. After the servo motor 37 rotates forward to reach the second set position, the servo motor 37 feeds back the fifth signal (indicating that the servo motor 37 rotates forward for the second time and the horizontal movable trolley 18 moves to the second set position, that is, the fork support plate 40 has completed the forking of the coil 19) to the control end. At the same time, the third photoelectric proximity switch 10 detects that there is cargo and feeds back the sixth signal (indicating that there is cargo on the fork) to the control end. After receiving the fifth and sixth signals, the control end controls the lifting power cylinder 25 to move and controls the servo motor 37 to stop operating.

[0054] Step 6, the lifting power cylinder 25 is actuated to extend its piston rod until the lifting detection plate 31 on the fork and lifting mechanism 12 reaches the second slot-shaped photoelectric switch 32, and the second slot-shaped photoelectric switch 32 feeds back the seventh signal (indicating that the coil 19 is already on the fork and lifting mechanism 12 and lifted to the set height, that is, the inner hole of the coil 19 is concentric with the fixed axis of the workshop processing equipment) to the control end. After receiving the seventh signal, the control end controls the lifting power cylinder 25 to stop and maintain pressure, and at the same time controls the servo motor 37 to reverse.

[0055] Step 7, the servo motor 37 reverses, and the horizontal moving trolley 18 withdraws from the material picking position until it reaches the third set position of the servo motor 37. The servo motor 37 feeds back the eighth signal (indicating that the horizontal moving trolley 18 has withdrawn from the safe position a certain distance) to the control end. After receiving the eighth signal, the control end controls the servo motor 37 to stop operating, and at the same time, the rotary power cylinder 1 is actuated.

[0056] Step 8, the piston rod of the rotary power cylinder 1 begins to retract until the flip frame 2 rotates from 90 degrees to 45 degrees. The second photoelectric proximity switch 29 on the arc-shaped in-position detection plate 30 detects the ninth signal (indicating that the flip frame 2 rotates from 90 degrees to 45 degrees) and feeds it back to the control end. The control end receives the ninth signal and controls the servo motor 37 to reverse. At the same time, the control end controls the rotary power cylinder 1 to stop moving, and the flip frame 2 returns to the initial position of 45 degrees.

[0057] Step 9, the control end controls the servo motor 37 to start reverse rotation, moves to the workshop processing equipment until it reaches the fourth set position of the servo motor 37, and then feeds back the tenth signal (indicating that the horizontal moving trolley 18 has reached the loading position of the workshop processing equipment) to the control end. After receiving the tenth signal, the control end controls the rotation of the power cylinder 1, and the servo motor 37 stops operating.

[0058] Step 10, the rotary power cylinder 1 is actuated, and its piston rod begins to extend. The first photoelectric proximity switch 28 on the arc-in-place detection plate 30 feeds back the eleventh signal (indicating that the flip frame 2 rotates from 45 degrees to 90 degrees) to the control end. The control end receives the eleventh signal, controls the rotary power cylinder 1 to stop operating and be in a pressure-maintaining state, and at the same time, the servo motor 37 reverses.

[0059] Step 11, the servo motor 37 reverses, and the horizontal movable carriage 18 moves toward the workshop processing equipment end until it reaches the fifth set position of the servo motor 37. The servo motor 37 feeds back the twelfth signal (indicating that the coil 19 has been successfully loaded on the workshop processing equipment) to the control end. After receiving the twelfth signal, the control end controls the servo motor 37 to rotate forward.

[0060] Step 12, the servo motor 37 rotates forward to make the horizontal movable trolley 18 withdraw from the loading position of the workshop processing equipment until the horizontal movable trolley 18 moves to the initial position (without hindering the operation of the workshop processing equipment), the servo motor 37 feeds back the thirteenth signal (indicating that the horizontal movable trolley 18 returns to the initial position) to the control end, the control end controls the lifting power cylinder 25 to retract to the initial position (the turning frame 2 rotates from 90 degrees to 45 degrees), the first slot-shaped photoelectric switch 33 feeds back the fourteenth signal (indicating that the lifting power cylinder 25 returns to the initial position) to the control end, the control end receives the thirteenth signal and the fourteenth signal, and the equipment will stop running only when the horizontal movable trolley 18 and the lifting power cylinder 25 return to the initial position, completing the automatic transportation and loading of the coil 19.
