Description

TECHNICAL FIELD

[0001] The application relates to a material taking device for an automatic spring machine. BACKGROUND

[0002] The core feeding mechanism of the automatic spring machine relies on one or two pairs of feeding wheels to form a stable compression state of the steel wire. When working, the feeding wheels generate driving force through rotation to drive the steel wire to accurately feed in a straight line. This transmission process is realized by the meshing of the sectoral incomplete gear and the gear on the feeding wheel shaft. Among them, the upper and lower feeding wheels maintain the same speed, but the rotation directions are opposite, so as to ensure that the steel wire is balanced in force and runs stably during feeding.

[0003] In actual production application, the automatic spring machine makes the steel wire into various springs, and directly cuts the completed spring. The cut spring directly falls to the ground, which is easy to cause scratches on the surface of the spring product, thereby reducing the qualified rate of the product. Some solutions are given in the prior art, such as Chinese patent CN212355563U, published on January 15, 2021, which discloses a material taking device of a multi-station full-automatic spring machine, comprising a spring machine body and a supporting plate. The supporting plate is located at the middle position of the side surface of the spring machine body. The top of the supporting plate is provided with an adjusting mechanism. The adjusting mechanism comprises a first fixed block, a second fixed block, a lead screw, a hand wheel and a sliding block. A material receiving plate is arranged on the sliding block. A connecting plate is arranged on the material receiving plate. The side of the connecting plate is provided with a material box. The designed material receiving plate and material box make the falling spring first fall on the material receiving plate and then roll into the material box, so as to facilitate the collection of spring products. In addition, the position of the material receiving plate can be adjusted simply, so as to facilitate the collection of spring products of different sizes.

[0004] However, when the length of the manufactured spring is relatively long, the outermost end of the spring will move downward due to its own weight as the length of the spring extends, which is easy to cause the spring to bend and reduce the qualified rate of the product. In addition, when the length of the manufactured spring is relatively short, the automatic spring machine will fly outward at the moment of spring fracture when cutting the spring due to the large cutting force, so that the spring cannot fall into the collection box below, which makes the subsequent collection difficult, time-consuming and laborious, and increases the labor intensity of workers. SUMMARY

[0005] The technical problem to be solved by the present application is that the existing automatic spring machine is prone to cause the outermost end of the spring to move downward due to the weight of the spring when manufacturing a longer spring, which easily causes the spring to bend and reduces the qualified rate of the product, and when manufacturing a shorter spring, the spring will fly outward at the moment of breaking due to the large shearing force, which cannot fall into the collection box directly below, causing subsequent collection to be difficult and time-consuming and increasing the labor intensity of workers.

Detailed Implementation

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 8 As shown, an automatic spring machine material handling device includes: a support leg 1, a support plate 2, a worktable 3, a collection box 4, a spring machine body 5, and a material handling mechanism 6; A support plate 2 is fixedly installed in the middle of multiple legs 1, a workbench 3 is fixedly installed on the top of multiple legs 1, a collection box 4 is fixedly installed on the support plate 2 and the collection box 4 passes through the workbench 3, a spring machine body 5 is fixedly installed on the workbench 3, and a material picking mechanism 6 is fixedly installed on the collection box 4. When the spring is being made by the spring machine body 5, the spring will enter the inside of the material taking mechanism 6 and support and maintain the horizontal spiral movement of the spring, driving the material taking mechanism 6 to rotate and send the spring into the collection box 4.

[0030] The support legs 1 are made of high-strength metal. A support plate 2 is horizontally fixed to the middle of the multiple support legs 1 by bolts. The spring machine body 5 is fixed to the preset position of the worktable 3 by bolt assembly. The collection box 4 has a box structure with an open top. The box body of the collection box 4 passes through the through hole of the worktable 3 from top to bottom. The feeding end of the picking mechanism 6 is coaxially aligned with the discharging end of the spring machine body 5 to ensure that the springs processed by the spring machine body 5 can accurately enter the picking mechanism 6.

[0031] With the gradual formation of the spring helical structure, the end of the spring will continue to stretch in the horizontal direction. Because the feeding end of the taking mechanism 6 is accurately aligned with the discharging end of the spring machine body 5, the stretched spring will naturally enter the inside of the taking mechanism 6, at which time the taking mechanism 6 supports and keeps the spring stable in the horizontal direction to move in a spiral, avoiding the spring from tilting, jamming or deforming during the conveying process, and ensuring that the spring posture and processing rhythm are completely matched.

[0032] When the spring machine body 5 completes the processing of a single spring and separates it by shearing, the taking mechanism 6 immediately drives the conveying channel of the taking mechanism 6 to rotate from the horizontal state to the vertical state through the internal drive motor 67. After the rotation action is completed, the spring inside the taking mechanism 6 loses horizontal support and falls along the vertical channel under the action of its own gravity, smoothly entering the inside of the collection box 4.

[0033] As shown in Figures 2 to 5 , the taking mechanism 6 includes connecting rods 61, discs 62, rotating discs 63, taking modules 64, rectangular blocks 65, drive shafts 66 and drive motors 67. One end of each of the two connecting rods 61 is fixedly installed on the inside of the collection box 4, and the other end of each of the two connecting rods 61 is fixedly installed with a disc 62, and an arc-shaped block 621 is fixedly connected between the two discs 62. The rotating disc 63 is rotatably installed between the two discs 62, and the rotating disc 63 is located on the inside of the arc-shaped block 621. The taking module 64 is fixedly installed on the rotating disc 63. The rectangular block 65 is fixedly installed on the outside of any one of the discs 62. The drive shaft 66 is arranged at the bottom of the rectangular block 65, and the drive motor 67 is fixedly installed on the drive shaft 66. The drive motor 67 is fixedly connected with the workbench 3.

[0034] One end of each of the two connecting rods 61 is fixedly installed on the inside of the collection box 4 by welding. The two discs 62 have the same diameter. An arc-shaped block 621 is fixedly connected at the edge position of the two discs 62 by bolts, and is rotatably installed between the two discs 62, so that the rotating disc 63 can flexibly rotate around the axis. The feeding end of the taking module 64 faces the direction of the spring machine body 5, and is coaxially aligned with the discharging end of the spring machine body 5, so as to ensure that the spring can smoothly enter the inside of the taking module 64. The discharging end of the taking module 64 faces the collection box 4.

[0035] The main function of the rectangular block 65 is to provide installation support for the drive shaft 66, and to stably transmit the power of the drive motor 67 to the rotating disc 63. The drive motor 67 is fixedly installed on the workbench 3, and the installation position is aligned with the axis of the drive shaft 66, so as to ensure that the output shaft of the drive motor 67 can be accurately connected with the drive shaft 66 through a shaft coupling. At the same time, the drive motor 67 is electrically connected with the control system, and can be automatically started or stopped according to the spring processing progress, so as to ensure that the direction conversion of the taking module 64 is accurately in place.

[0036] As shown in Figure 5 and Figure 6 , the outer side of the disc 62 near one side of the rectangular block 65 is provided with a rectangular recess 623, and the inner side of the disc 62 near one side of the rectangular block 65 is provided with an annular recess 624, and the annular recess 624 and the rectangular recess 623 are mutually penetrated.

[0037] The rectangular recess 623 and the annular recess 624 are mutually communicated, which provides a mounting space for the subsequent installation of the driving shaft 66 and the transmission of power, so that the rotation of the driving shaft 66 can transmit power to the rotating disc 63, so that the rotating disc 63 rotates.

[0038] As shown in Figure 6 , the outer side of the arc-shaped block 621 is provided with a discharging cylinder 622, and the inner side of the arc-shaped block 621 is provided with a circular hole 625, and the circular hole 625 and the discharging cylinder 622 are mutually penetrated.

[0039] When the rotating disc 63 drives the material taking module 64 to rotate to the vertical state, the discharging end of the material taking module 64 can be completely docked with the circular hole 625, so that the spring can directly enter the circular hole 625 from the material taking module 64. The inner diameter of the circular hole 625 is consistent with the inner diameter of the discharging cylinder 622. When the material taking mechanism 6 is not working, the rotating disc 63 is in a horizontal state, and the discharging end of the material taking module 64 is in a staggered state with the circular hole 625 on the inner side of the arc-shaped block 621; when the spring completes the posture adjustment in the material taking module 64, the rotating disc 63 is rotated 90° to the vertical state under the driving of the driving assembly, at this time, the discharging end of the material taking module 64 is aligned with the circular hole 625 on the inner side of the arc-shaped block 621, forming a channel. Since the inner diameter of the circular hole 625 is the same as the inner diameter of the discharging end of the material taking module 64, and the butt joint gap is very small, the spring can smoothly slide into the circular hole 625 under the action of its own gravity, and directly fall into the collecting box 4 through the discharging cylinder 622.

[0040] As shown in Figure 7 and Figure 8 , a circular hole 631 is formed on the circumferential outer wall of the rotating disc 63, and a plurality of fixed teeth 632 are arranged in an annular array on the side of the rotating disc 63 near the rectangular block 65 with the axis as the center, and the plurality of fixed teeth 632 are respectively located inside the annular recess 624.

[0041] The circular through hole 631 has a precise positional correlation with the material taking module 64 fixedly installed on the rotating disc 63: the internal passage of the material taking module 64 is coaxially communicated with the circular through hole 631, and after the spring completes the horizontal spiral movement in the material taking module 64 and is cut off, the spring directly enters the passage of the material taking module 64 and then slides into the circular through hole 631. When the rotating disc 63 is in a horizontal state, the axis of the circular through hole 631 is consistent with the discharging direction of the spring machine body 5, facilitating the receiving of the spring; when the rotating disc 63 is rotated 90° to a vertical state under the driving of the driving motor 67, the axis of the circular through hole 631 is turned to a vertical direction, and at this time, the circular through hole 631 is completely aligned with the circular hole 625 inside the arc block 621, and the spring can stably fall into the circular hole 625 of the arc block 621 along the circular through hole 631 under the action of its own gravity, realizing the falling of the spring from the rotating disc 63 into the collecting box 4 for collection.

[0042] When the driving motor 67 starts and drives the rotating tooth 655 to rotate, the rotating tooth 655 will precisely mesh with the fixed tooth 632 in the annular groove 624, transmitting power to the rotating disc 63 to drive the rotating disc 63 to rotate around the central axis. The annular groove 624 limits the meshing area of the fixed tooth 632 and the rotating tooth 655, ensuring that they always mesh on the preset circumferential track, avoiding power transmission efficiency decline or component damage due to meshing position deviation.

[0043] The diameter value of the circular through hole 631 is equal to the diameter value of the circular hole 625, and the diameter values of the circular through hole 631 and the circular hole 625 are greater than the diameter value of the spring.

[0044] The diameter consistency of the circular through hole 631 and the circular hole 625 is that the inner walls of the two can form a seamless spliced passage without any gap or misplacement, further stabilizing the conveying posture of the spring and ensuring that the spring always falls along the axial direction of the passage. The diameters of the circular through hole 631 and the circular hole 625 are greater than the diameter of the spring, which is to reserve a reasonable gap to avoid the jamming of the spring during falling, and at the same time, to ensure that the spring can enter the interior of the circular through hole 631 and the circular hole 625.

[0045] As shown in Figure 8 the material taking module 64 includes a cylindrical barrel 641, a lightweight compression spring 642, a moving barrel 643, and a ball 644; The cylindrical barrel 641 is fixedly installed on the circumferential outer wall of the rotating disc 63 and located at one end of the circular through hole 631, the lightweight compression spring 642 is fixedly installed on the inner wall of the cylindrical barrel 641, the circumferential outer wall of the moving barrel 643 is annularly arranged with a plurality of balls 644, the moving barrel 643 is movably installed on the inner wall of the cylindrical barrel 641 and located at the outer side of the lightweight compression spring 642, and the plurality of balls 644 roll on the inner wall of the cylindrical barrel 641.

[0046] The inner wall of the cylindrical barrel 641 near one end of the rotating disc 63 is provided with an annular step for limiting the installation position of the lightweight compression spring 642 to prevent the spring from deviating towards the circular through hole 631 during compression; the middle to the other end of the inner wall is a smooth cylindrical surface to provide a track for the axial movement of the moving barrel 643 and the rolling of the ball 644, ensuring that the moving barrel 643 can slide smoothly along the inner wall without the risk of jamming or sticking.

[0047] The main function of the lightweight compression spring 642 is to reset. During the manufacturing process of the spring, the lightweight compression spring 642 will be compressed. When the spring falls into the collection box 4, the lightweight compression spring 642 will drive the moving barrel 643 to move outward and reset through its elastic potential energy.

[0048] When the spring processed by the spring machine body 5 enters the moving barrel 643 and drives the moving barrel 643 to move along the inner wall of the cylindrical barrel 641 towards the circular through hole 631, the moving barrel 643 will compress the lightweight compression spring 642, causing the spring to compress and deform. At the same time, the rolling contact of the ball 644 replaces the sliding contact between the moving barrel 643 and the inner wall of the cylindrical barrel 641, converting sliding friction into rolling friction, greatly reducing the frictional resistance between the two, making the movement of the moving barrel 643 along the inner wall of the cylindrical barrel 641 more smooth and stable, reducing the movement jam caused by excessive frictional resistance, and thus ensuring that the conveying rhythm of the spring is synchronized with the processing rhythm of the spring machine body 5.

[0049] The ball 644 is used to reduce the resistance of the moving barrel 643 during movement, ensuring that the moving barrel 643 can also rotate during horizontal movement.

[0050] As shown in Figure 8 The moving barrel 643 and the lightweight compression spring 642 are connected by the rotating ring 645.

[0051] It should be noted that in order to ensure that the moving barrel 643 can compress the lightweight compression spring 642 during spiral movement, and also ensure that the moving barrel 643 rotates, the rotating ring 645 is installed between the lightweight compression spring 642 and the moving barrel 643. During spiral movement, the moving barrel 643 can both push the rotating ring 645 to compress the lightweight compression spring 642 and rotate on the rotating ring 645.

[0052] As shown in Figure 4As shown, the first cavity 651 and the second cavity 652 are respectively arranged in the rectangular block 65, the driving shaft 66 penetrates the second cavity 652, the first bevel gear 661 is arranged on one end of the driving shaft 66 in the second cavity 652, the rotating shaft 653 is rotatably arranged between the first cavity 651 and the second cavity 652, the second bevel gear 654 is arranged on one end of the rotating shaft 653 in the second cavity 652, and the second bevel gear 654 is meshed with the first bevel gear 661, the rotating teeth 655 are arranged on one end of the rotating shaft 653 in the first cavity 651, and the rotating teeth 655 are meshed with the plurality of fixed teeth 632.

[0053] The rotating shaft 653 is installed between the first cavity 651 and the second cavity 652 through the bearing seat, so as to ensure that the rotating shaft 653 can stably rotate around its own axis. The length of the rotating shaft 653 is designed according to the distance between the two cavities, the second bevel gear 654 is perpendicularly meshed with the first bevel gear 661 at 90°, when the driving shaft 66 drives the first bevel gear 661 to rotate, the second bevel gear 654 will synchronously rotate, and power is transmitted to the rotating shaft 653, the rotating shaft 653 drives the rotating teeth 655 to rotate, the rotating teeth 655 extend out of the first cavity 651 and are meshed with the fixed teeth 632 on the rotating disc 63, when the rotating shaft 653 drives the rotating teeth 655 to rotate, the rotating teeth 655 will drive the fixed teeth 632 to synchronously rotate, and then drive the rotating disc 63 to rotate around its own axis, so as to realize the transmission of power.

[0054] As shown in the figure, Figure 2 The collecting box 4 is provided with an inclined bottom plate 41 at the bottom and an inclined plate 42 at the top, the distance between the bottom edge of the inclined plate 42 and the inner wall of the collecting box 4 is equal to the diameter of the spring, and the two sides of the collecting box 4 are provided with support blocks 43, and the inner sides of the two support blocks 43 are fixedly connected with the two connecting rods 61 respectively.

[0055] The inclined bottom plate 41 is fixed on the bottom inner wall of the collecting box 4 by welding, and the inclined direction is towards one side of the collecting box 4, for guiding the falling spring to the other side of the collecting box 4, The inclined plate 42 is used for receiving the spring vertically falling from the discharging cylinder 622, and guiding the spring posture conversion through the inclined surface, after the spring falls from the discharging cylinder 622, it impacts the surface of the inclined plate 42, under the joint action of the gravity component force and the support force of the inclined plate 42, the vertical falling posture is gradually changed into the horizontal posture of rolling along the inclined plate 42, and the preparation for subsequent entering the bottom of the collecting box 4 is made.

[0056] The distance value between the bottom edge of the inclined plate 42 and the inner wall of the collecting box 4 is strictly set to be equal to the diameter value of the spring. On the one hand, the distance is completely matched with the diameter of the spring, which can ensure that the spring does not tilt or overturn due to the too large distance when passing through the gap in a horizontal posture, and the spring does not jam due to the too small distance. On the other hand, when the spring rolls to the bottom edge along the inclined plate 42, the spring in a horizontal posture will be embedded in the gap between the edge of the inclined plate 42 and the inner wall of the collecting box 4, and will fall smoothly to the inclined bottom plate 41 below under the action of its own gravity.

[0057] The support block 43 not only bears the support function of the material taking mechanism 6, but also ensures the relative position of the material taking mechanism 6 and the collecting box 4 to be fixed through accurate position positioning. Since the support block 43 is rigidly connected with the collecting box 4, and the connecting rod 61 is fixed with the support block 43, the discharge cylinder 622 of the material taking mechanism 6 can always maintain the opposite position of the top inclined plate 42 of the collecting box 4, so as to avoid that the spring cannot be accurately dropped on the inclined plate 42 due to the deviation of the material taking mechanism 6.

[0058] The working process of the present application is as follows: first, during the process of manufacturing the spring, the spring machine body 5 is used to make the spring spiral out, and the spring will enter the moving cylinder 643 on the material taking module 64. The inner wall of the moving cylinder 643 will be in contact with the spring, and there is a certain friction force between them. With the spiral horizontal movement of the spring, the moving cylinder 643 will make spiral horizontal movement in the cylindrical cylinder 641. During the rotation of the moving cylinder 643 on the rotating ring 645, pressure is applied to the rotating ring 645, so that the rotating ring 645 moves axially and pushes and compresses the light compression spring 642, so that the spring always maintains a horizontal direction. After the spring is completed, the spring is cut by the spring machine body 5.

[0059] When the spring cutting is completed, the driving motor 67 is started, and the first bevel gear 661 is rotated through the driving shaft 66. Since the first bevel gear 661 is meshed with the second bevel gear 654, the second bevel gear 654 is rotated. The second bevel gear 654 transmits power to the rotating shaft 653, and the rotating tooth 655 is rotated through the rotating shaft 653. Since the rotating tooth 655 is meshed with the fixed tooth 632 on the rotating disc 63, the entire rotating disc 63 is rotated from the horizontal direction to the vertical direction, and the entire rotation angle is 90°. When the rotating disc 63 is rotated to the vertical direction, the circular through hole 631 on the rotating disc 63 and the circular hole 625 on the arc block 621 are connected, and the axis lines are coincided with each other. At this time, the completed spring moves downward from the cylindrical cylinder 641 through its own gravity, passes through the circular through hole 631, and enters the discharge cylinder 622.

[0060] Since the discharge cylinder 622 is located above the chute 42 of the collection box 4, the spring will freely fall from the discharge cylinder 622 to the chute 42. After the spring contacts the chute 42, the posture of the spring will change from vertical to horizontal due to the self-gravity and the guiding of the inclined state of the chute 42. The spring falls through the gap between the chute 42 and the inner wall of the collection box 4 and lands on the inclined bottom plate 41 at the bottom of the collection box 4. The spring rolls to the lowest point of the inclined bottom plate 41 by its own gravity, thereby completing the collection of the entire spring.
