Description

Technical Field

[0001] This invention relates to the field of steel cage production, and in particular to an active feeding disc mechanism with clutch braking. Background Technology

[0002] As is well known, in the process of producing steel bars, in order to facilitate the collection, storage and subsequent transportation of the steel bars, the produced steel bars are required to be rolled into rolls.

[0003] In the process of using coiled steel bars, the coiled steel bars are generally fitted onto the material tray mechanism so that the coiled steel bars can rotate with the assistance of the material tray in the material tray mechanism. Therefore, with the traction and cooperation of other external equipment, the material tray mechanism actively drives the material tray to rotate, and the rotating material tray achieves the purpose of releasing the steel bars it carries.

[0004] However, in the existing material tray mechanism, it requires frequent starting and stopping of the rotary motor to control the length of the feeding ribs. At the same time, relying on the starting and stopping of the rotary motor to control the length of the feeding ribs still has the drawback of being difficult to control.

[0005] Therefore, there is an urgent need for an active feeding disc mechanism with clutch braking that can accurately control the feeding length of the ribs while avoiding frequent start-stop of the rotating motor, in order to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide an active feeding disc mechanism with clutch braking that can accurately control the feeding length of the ribs while avoiding frequent start-stop of the rotary motor.

[0007] To achieve the above objectives, the active feeding tray mechanism with clutch and brake of the present invention includes a frame, a rotating shaft, a rotary motor, a tray for carrying coiled ribs, a reducer, a clutch, and a brake. The rotating shaft is rotatably mounted on the frame and extends vertically along the frame; the tray is mounted on the rotating shaft and rotates relative to the frame with the rotating shaft; the reducer is mounted on the frame and located below the tray; the brake is located below the tray and mounted on the frame, and the brake selectively engages or disengages the rotating shaft; the clutch is located below the tray and is mounted between the output shaft of the rotary motor and the input shaft of the reducer, with the output shaft of the clutch being drive-connected to the rotating shaft; alternatively, the input shaft of the clutch is drive-connected to the output shaft of the rotary motor, and the clutch is mounted between the output shaft of the reducer and the rotating shaft.

[0008] Preferably, the brake includes a fixed hinge seat, a first link, a second link, and a clamping actuator that together surround the rotating shaft. The first link and the second link are arranged opposite to each other, and the fixed hinge seat and the clamping actuator are arranged opposite to each other. The fixed hinge seat is fixed to the frame. The first ends of both the first link and the second link are hinged to the fixed hinge seat. The actuator body of the clamping actuator is hinged to the second end of the first link. The telescopic rod of the clamping actuator is connected to the second end of the second link. A first clamping block is mounted on the first link at a position between its first and second ends. A second clamping block is mounted on the second link at a position between its first and second ends. The first clamping block and the second clamping block face each other. A wheel is fixedly mounted on the rotating shaft between the first clamping block and the second clamping block.

[0009] Preferably, the first and second blocks each have an arcuate profile for engaging with the wheel.

[0010] Preferably, the brake further includes an auxiliary actuator arranged opposite to the clamping actuator and a third link arranged opposite to the first link and abutting the second link. The first end of the third link is hinged to the second end of the second link. The actuator body of the auxiliary actuator is hinged to the second end of the first link. The telescopic rod of the auxiliary actuator is hinged to the second end of the third link. The clamping actuator is located between the fixed hinge seat and the auxiliary actuator.

[0011] Preferably, the active feeding tray mechanism with clutch braking of the present invention further includes an intermediate driver located between the clamping driver and the auxiliary driver, the driver body of the intermediate driver being hinged to the first connecting rod, and the third connecting rod being hinged to the telescopic rod of the intermediate driver at a position between its first end and second end.

[0012] Preferably, the hinge center line of the third link and the second link and the hinge center line of the telescopic rod of the clamping actuator coincide with the hinge center line of the second link.

[0013] Preferably, the input shaft of the reducer is arranged in a horizontal direction, the output shaft of the reducer is arranged in a vertical direction, the output shaft of the reducer is equipped with a first pulley, the rotating shaft is equipped with a second pulley aligned with the first pulley, and a belt is fitted onto the first pulley and the second pulley.

[0014] Preferably, the second pulley is located below the brake.

[0015] Preferably, the brake is located inside the mechanism frame, and the material tray is located directly above the mechanism frame.

[0016] Preferably, the mechanism frame has an upper frame and a lower frame spaced apart from each other, each of the upper and lower frames being equipped with a bearing seat. The upper end of the rotating shaft is fitted into the bearing seat of the upper frame, and the upper end of the rotating shaft also extends upward beyond the bearing seat of the upper frame. The lower end of the rotating shaft is fitted into the bearing seat of the lower frame, and the lower end of the rotating shaft also extends upward beyond the bearing seat of the lower frame. The brake is located between the upper and lower frames.

[0017] Compared with existing technologies, the use of clutches and brakes allows for precise control of the feeding length of the ribs without frequent start-stop of the rotary motor. At the same time, the use of a reducer enables the rotary motor to drive the shaft to rotate at a higher torque and lower speed than the rotary motor itself, thus driving the material tray to rotate more reliably.

[0021] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0022] Please see Figures 1 to 3The active feeding tray mechanism 100 with clutch and brake of the present invention includes a mechanism frame 10, a rotating shaft 20, a rotary motor 30, a tray 40 for carrying coiled ribs, a reducer 50, a clutch 60, and a brake 70. The rotating shaft 20 is rotatably mounted on the mechanism frame 10 and extends along the vertical direction of the mechanism frame 10, so that the rotating shaft 20 is vertically arranged on the mechanism frame 10. The tray 40 is mounted on the rotating shaft 20 and rotates relative to the mechanism frame 10 with the rotating shaft 20, so that the tray 40 rotates horizontally on the mechanism frame 10. The reducer 50 is mounted on the mechanism frame 10 and located below the tray 40, and the brake 70 is located below the tray 40 and mounted on the mechanism frame 10. The brake 70 selectively engages or disengages the rotating shaft 20. The clutch 60 is located below the material tray 40. The clutch 60 is mounted between the output shaft of the rotary motor 30 and the input shaft of the reducer 50, and the output shaft of the clutch 60 is connected to the rotating shaft 20. Alternatively, in other embodiments, the input shaft of the clutch 60 can be connected to the output shaft of the rotary motor 30, in which case the clutch 60 is mounted between the output shaft of the reducer 50 and the rotating shaft 20. This achieves the same purpose of using the clutch 60 to ensure that the rotary motor 30 drives or does not drive the rotating shaft 20 to rotate. More specifically, as follows:

[0023] like Figure 1 and Figure 2 As shown, the brake 70 is located inside the mechanism frame 10, and the material tray 40 is located directly above the mechanism frame 10. This arrangement avoids the need to create an open structure around the material tray 40, which would complicate the structure of the mechanism frame 10. Therefore, placing the material tray 40 outside the mechanism frame 10 simplifies its structure. Simultaneously, placing the brake 70 inside the mechanism frame 10 reduces the space occupied by the brake 70 on the exterior of the mechanism frame 10 and ensures the reliability of the brake 70's braking of the rotating shaft 20. Specifically, in Figure 1 and Figure 2 In the design, the frame 10 has an upper frame 11 and a lower frame 12 that are spaced apart from each other. Each of the upper frame 11 and the lower frame 12 is equipped with a bearing seat 13. The upper end of the rotating shaft 20 is fitted to the bearing seat 13 of the upper frame 11, and the upper end of the rotating shaft 20 also extends upward from the bearing seat 13 of the upper frame 11. The lower end of the rotating shaft 20 is fitted to the bearing seat 13 of the lower frame 12, and the lower end of the rotating shaft 20 also extends upward from the bearing seat 13 of the lower frame 12. The brake 70 is located between the upper frame 11 and the lower frame 12. The purpose of this design is to increase the load-bearing capacity of the frame 10 on the rotating shaft 20 while improving the smoothness of the rotation of the rotating shaft 20 relative to the frame 10.

[0024] like Figure 3As shown, the brake 70 includes a fixed hinge 71 that collectively surrounds the pivot 20, a first link 72, a second link 73, and a clamping actuator 74. The first link 72 and the second link 73 are arranged opposite each other, for example, but not limited to... Figure 1 The first link 72 is located on the left and the second link 73 is located on the right; the fixed hinge 71 is arranged opposite to the clamping actuator 74, for example, but not limited to Figure 1 The fixed hinge seat 71 is located at the rear, while the clamping actuator 74 is located at the front. The fixed hinge seat 71 is fixed to the frame 10, preferably to the upper frame 11. The first ends of the first link 72 and the second link 73 are each hinged to the fixed hinge seat 71. The actuator body 741 of the clamping actuator 74 is hinged to the second end of the first link 72. The telescopic rod 742 of the clamping actuator 74 is connected to the second end of the second link 73. A first clamping block 75 is mounted on the first link 72 at a position between its first and second ends, and a second clamping block 76 is mounted on the second link 73 at a position between its first and second ends. The first clamping block 75 and the second clamping block 76 face each other, for example, but not limited to... Figure 3 The first clamping block 75 and the second clamping block 76 are arranged facing each other from left to right; a rotating shaft 20 is fixedly fitted with a disc 22 located between the first clamping block 75 and the second clamping block 76; this design makes the brake 70's clamping braking of the rotating shaft 20 more reliable and simplifies the structure of the brake 70. Specifically, in Figure 3 In the brake 70, an auxiliary actuator 77 is arranged opposite to the clamping actuator 74, and a third link 78 is arranged opposite to the first link 72 and docked with the second link 73. The first end of the third link 78 is hinged to the second end of the second link 73. The actuator body 771 of the auxiliary actuator 77 is hinged to the second end of the first link 72. The telescopic rod 772 of the auxiliary actuator 77 is hinged to the second end of the third link 78. The clamping actuator 74 is located between the fixed hinge seat 71 and the auxiliary actuator 77. With the cooperation of the auxiliary actuator 77 and the third link 78, a second clamping force is provided for the first clamping block 75 and the second clamping block 76 to clamp the wheel disc 22, effectively avoiding the defect of unreliable clamping due to overload of the clamping actuator 74. More specifically, in Figure 3 In this invention, the active unloading disc mechanism 100 with clutch braking further includes an intermediate driver 79 located between the clamping driver 74 and the auxiliary driver 77. The driver body 791 of the intermediate driver 79 is hinged to the first connecting rod 72, and the third connecting rod 78, located between its first and second ends, is hinged to the telescopic rod 792 of the intermediate driver 79, providing a third clamping force for the first clamping block 75 and the second clamping block 76 to jointly clamp the disc 22, thereby more effectively avoiding the defect of unreliable clamping due to overload of the clamping driver 74. For example, in Figure 3In this configuration, the first clamping block 75 and the second clamping block 76 each have an arc-shaped profile 751 (761) for engaging with the wheel 22, thereby increasing the clamping contact area of ​​the first clamping block 75 and the second clamping block 76 with the wheel 22. Furthermore, the hinge center line of the third link 78 and the second link 73, and the hinge center line of the telescopic rod 742 of the clamping actuator 74, coincide with the hinge center line of the second link 73, achieving coaxial hinge connection between the second link 73, the third link 78, and the telescopic rod 742 of the clamping actuator 74. Figure 3 The C in the middle refers to simplifying their structure, but is not limited to this.

[0025] like Figure 1 and Figure 2 As shown, the input shaft of the reducer 50 is arranged horizontally, and the output shaft of the reducer 50 is arranged vertically. A first pulley 53 is mounted on the output shaft of the reducer 50, and a second pulley 22 aligned with the first pulley 53 is mounted on the rotating shaft 20. A belt is fitted onto the first pulley 53 and the second pulley 22 to achieve the purpose of the reducer 50 driving the rotating shaft 20 to rotate smoothly over a long distance. Specifically, in Figure 1 and Figure 2 In the middle, the second pulley 22 is located below the brake 70 so that their arrangement on the mechanism frame 10 is more reasonable.

[0026] Referring to the accompanying drawings, the working principle of the active feeding disc mechanism with clutch and brake of the present invention will be explained as follows: During the continuous operation of the rotary motor 30, the clutch 60 and the reducer 50 drive the rotating shaft 20 and the feeding disc 40 to rotate together, thereby realizing the feeding function of the ribs carried by the feeding disc 40; when the feeding length of the ribs reaches the desired length, the clutch 60 disconnects the reducer 50 from the rotary motor 30, so that the continuously operating rotary motor 30 can no longer drive the rotating shaft 20 and the feeding disc 40 to rotate together. At the same time, the brake 70 clamps the wheel 22 of the rotating shaft 20, as shown in the figure. Figure 3 As shown, this achieves the purpose of stopping the rotation of the rotating shaft 20 and the material tray 40. Specifically, in... Figure 3 In the braking process of the brake 70 on the turntable 22 of the turntable 20, the clamping actuator 74 drives the first link 72 and the second link 73 to pivot closer to each other, so that the first clamping block 75 on the first link 72 and the second clamping block 76 on the second link 73 jointly clamp the turntable 22. At the same time, the auxiliary actuator 77 and the intermediate actuator 79 work synchronously and in the same direction, causing the third link 78 to pivot closer to the first link 72, providing a second and third force for the first clamping block 75 and the second clamping block 76 to jointly clamp the turntable 22. It should be noted that the clamping actuator 74, the auxiliary actuator 77 and the intermediate actuator 79 are each a pneumatic cylinder or a hydraulic cylinder.

[0027] Compared with the prior art, by means of the clutch 60 and the brake 70, the feeding length of the rib can be precisely controlled without the frequent start and stop of the rotary motor 30. That is, the active feeding disc mechanism 100 of the present invention can precisely control the feeding length of the rib by means of the clutch 60 and the brake 70 when the rotary motor 30 is working continuously. At the same time, with the help of the reducer 50, the rotary motor 30 drives the rotating shaft 20 to rotate at a higher torque and a lower speed than the rotary motor 30 through the reducer 50, thereby driving the material disc 40 to rotate more reliably.

[0028] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
