Description

Technical Field

[0001] The utility model belongs to the technical field of winding and unwinding, and particularly relates to a turret stopping mechanism and a winding and unwinding device. Background Art

[0002] The reeling and unwinding device is a common piece of industrial equipment, primarily used for winding and unwinding various materials. The reeling turret is a crucial component of the device. It is connected to a support via a shaft, and a reduction motor mounted on the support drives the shaft, which in turn rotates on the support. When the material needs to be wound or unwound, the reduction motor drives the shaft, which drives the turret to the corresponding station, where the reel mounted at that station begins to rotate. When the turret needs to stop, a stop mechanism drives the reduction motor to stop the turret.

[0003] Current turret stop mechanisms typically include a position sensor and a sensing plate. The position sensor is mounted at the appropriate position. When the sensing plate, mounted on the turret, enters the sensing range, the position sensor sends an electrical signal to the reduction motor, driving the reduction motor to stop, thereby stopping the turret. However, this requires the reduction motor to stop suddenly upon receiving the electrical signal, placing high demands on the reduction motor and its associated rotating components, significantly impacting their service life and posing certain safety risks during operation.

[0033] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0035] In the following embodiments and drawings, reference is made to Figure 1 In the coordinate system, the direction indicated by the arrow of the X axis is right, the direction indicated by the arrow of the Y axis is forward, and the direction indicated by the arrow of the Z axis is up.

[0036] Example 1:

[0037] like Figures 1 to 4 As shown, this embodiment provides a turret stopping mechanism, including: a sensing member 110 for installation on a rotating turntable 100, a mounting seat 300, a first position sensor 310 for controlling the deceleration of the reduction motor 200, and a second position sensor 320 for controlling the reduction motor 200 to stop rotating; the first position sensor 310 and the second position sensor 320 are arranged on the mounting seat 300, and the first position sensor 310 and the second position sensor 320 are inductively coupled to the sensing member 110 in turn.

[0038] Specifically, the mounting base 300 is arranged below the rotating turntable 100, and the first position sensor 310 and the second position sensor 320 are installed on the mounting base 300 through an L-shaped fixing plate. The two are arranged side by side along the X-axis direction. The first position sensor 310 is arranged on the left side of the second sensor, and is used to sense with the sensing element 110 and transmit the sensing signal to control the deceleration of the reduction motor 200; the second position sensor 320 is used to sense with the sensing element 110 and transmit the sensing signal to control the deceleration of the reduction motor 200; the sensing element 110 is arranged at the outer edge of the rotating turntable 100, and during the rotation of the rotating turntable 100, the sensing element 110 passes through the first position sensor 310 and the second position sensor 320 in sequence.

[0039] It is worth noting that when in use, the sensing member 110 on the rotating turntable 100 passes through the first position sensor 310, the first position sensor 310 senses the sensing member 110, and transmits the sensing signal to the reduction motor 200 to control the reduction motor 200 to decelerate, and the sensing member 110 continues to rotate to the second position sensor 320, the second position sensor 320 senses the sensing member 110, and transmits the sensing signal to the reduction motor 200 to control the reduction motor 200 to stop. In this way, compared with the prior art, the present application adopts the design of a dual-sensing positioning stop structure, so that the reduction motor has a deceleration buffer process before stopping, thereby avoiding high demands on the reduction motor and its related rotating parts, and enhancing the service life, making the operation safer and more effective. In addition, because it can stop rotating at a specified position, the rotation and stopping of the turret are more precise.

[0040] In order to make the induction effect stronger, Figure 3As shown, in some embodiments, the first position sensor 310 and the second position sensor 320 are both provided with a sensing portion 330 , and the sensing element 110 passes through the middle portions of the two sensing portions 330 in sequence during the rotation process.

[0041] Specifically, the top of the first sensor and the top of the second sensor are concavely provided with a sensing portion 330, that is, the cross-sectional shape of the first sensor and the second sensor is set to be concave, and the sensing element 110 moves over the concave part of the sensing portion 330, so that the distance between the sensing element 110 and the sensing portions 330 of the first position sensor 310 and the second position sensor 320 is closer, and the sensing effect is better.

[0042] In order to make the turret stop mechanism better able to stop, such as Figure 1 As shown, in some embodiments, at least two sensing elements 110 are provided.

[0043] Specifically, at least two sensing members 110 are evenly installed on the rotating turntable 100, and the number of sensing members 110 is optional but not limited to two. The sensing members 110 are installed on opposite sides of the edge of the rotating turntable 100. By setting the number of sensing members 110 to be greater, it is possible to stop at the required position in time, and avoid the need to rotate the single sensing member 110 to the position sensor before stopping when there is only one sensing member 110.

[0044] Example 2

[0045] This embodiment is a further implementation of embodiment 1. Figure 2 and Figure 3 As shown, in this embodiment, a limiting assembly 400 for limiting the rotation of the rotating turntable 100 is provided on the mounting seat 300 .

[0046] Specifically, the limit assembly 400 is mounted on the top of the mounting base 300 and is disposed adjacent to the first position sensor 310 and the second position sensor 320. The limit assembly 400 can prevent the rotating turntable 100 from continuing to rotate under inertia after the reduction motor 200 stops rotating.

[0047] In order to facilitate the use of the limiting component 400, as shown in FIG. Figures 2 to 6 As shown, in some embodiments, the limiting assembly 400 includes a locking driver 410, a limiting member 420 and a matching member 430 for installation on the rotating turntable 100. The locking driver 410 is arranged on the mounting seat 300, and the output end of the locking driver 410 is connected to the limiting member 420 to drive the limiting member 420 to be limitedly connected with the matching member 430.

[0048] Specifically, the fitting part 430 is installed at the circumferential edge of the rotating turntable 100; the locking driver 410 is installed on the rear side of the mounting base 300. The locking driver 410 is optional but not limited to a guide rod cylinder. The working mode of the guide rod cylinder is known to those skilled in the art and is feasible. It is not described in detail in this embodiment. The locking driver 410 pushes the limiting part 420 upward to approach the fitting part 430, so that the limiting part 420 and the fitting part 430 are connected in a limiting manner, thereby ensuring the realization of the limiting effect of the limiting component 400, and then achieving the purpose of limiting the rotation of the rotating turntable 100.

[0049] In this way, the limit piece 420 is pushed by the guide rod cylinder to limit the connection with the matching piece 430. At this time, no matter whether the balance lever of the rotating turntable 100 is balanced or not, the rotating turntable 100 will not rotate significantly. When the rotating turntable 100 needs to rotate the coil, the guide rod cylinder only needs to pull back the limit piece 420 to release the limit, which will not affect the original function of the turret at all, thereby greatly ensuring the safety of winding and unwinding.

[0050] In order to facilitate the limiting component 400 to limit, as shown in FIG. Figure 5 and Figure 6 As shown, in some embodiments, the limiting member 420 is engaged with the matching member 430 .

[0051] Specifically, the position-limiting member 420 is provided with a first engaging portion, and the mating member 430 is provided with a second engaging portion that mates with the first engaging portion. Thus, when the latching actuator 410 drives the position-limiting member 420 upward, the first engaging portion engages with the second engaging portion, thereby restricting the rotation of the rotating turntable 100. The specific structures of the first and second engaging portions are not limited herein; they only need to be able to engage with each other. For example, the first and second engaging portions can be configured as a structure where a block and a slot mate with each other.

[0052] In order to facilitate the locking of the limiting assembly 400 on the rotating turntable 100, as shown in FIG. Figure 5 and Figure 6 As shown, in some embodiments, the mating member 430 is configured as a cam bearing follower, and the limiting member 420 is provided with a limiting surface for engaging with the cam bearing follower.

[0053] Specifically, the limit member 420 is configured as a limit block, and the limit surface is concavely set at one end of the limit block close to the matching member 430, that is, the limit surface is set at the top of the limit block. The matching member 430 is optional but not limited to a cam bearing follower. The cam bearing follower is installed on the circumferential edge of the rotating turntable 100 through the follower mounting block, which serves as a protruding fulcrum to ensure the realization of the cam bearing follower's function. It is used to achieve line contact with the limit surface, thereby limiting the rotation of the rotating turntable 100.

[0054] In order to facilitate the use of the limiting component 400, as shown in FIG. Figure 3 and Figure 5 As shown, in some embodiments, the turret stopping mechanism further includes a positioning member installed on the rotating turntable 100 , and the matching member 430 and the sensing member 110 are adjacently arranged on the positioning member.

[0055] Specifically, the positioning member can be set as a follower mounting block, and the sensing member 110 is installed on the follower mounting block, that is, the sensing member 110 is arranged on the front side of the cam bearing follower, and the working end is spaced apart from the cam bearing follower, so that the sensing member 110 and the matching member 430 are arranged opposite each other in the Y-axis direction, so that after the reduction motor 200 stops, the matching member 430 can limit the rotating turntable 100, thereby making the limiting effect better.

[0056] Furthermore, the number of the fittings 430 is optional but not limited to two, and the fittings 430 are also correspondingly installed on two opposite sides of the edge of the rotating turntable 100 .

[0057] It is understood that the limiting assembly 400 can also be configured as other components, which is not limited here, and only needs to limit the rotation of the rotating turntable 100. For example, the limiting assembly 400 can also be configured to limit the rotation by a magnetic member.

[0060] Specifically, the reduction motor 200 drives the rotating turntable 100 to rotate, and the working mode of the reduction motor 200 is known to those skilled in the art and is achievable, and is not described in detail in this embodiment. The rotating turntable 100 rotates along Figure 1 The turntable 100 rotates in the direction indicated by the arrow, that is, clockwise, and a follower mounting block is installed on the outer peripheral edge of the turntable 100.

Figure 1 As shown, in some embodiments, the rewinding and unwinding device 10 also includes a support base 500 and a flip center shaft 600, the reduction motor 200 is installed on the support base 500, and the output end of the reduction motor 200 is connected to the flip center shaft 600, so that the flip center shaft 600 is rotatably set on the support base 500, and the rotating turntable 100 is connected to the flip center shaft 600.

[0062] Specifically, the support base 500 is used to support and fix the reduction motor 200, and the flip center shaft 600 is used to install the rotating turntable 100, so that the reduction motor 200 can drive the rotating turntable 100 to rotate, so that the reduction motor 200 can drive the rotating turntable 100 to rotate.

[0063] While working:

[0064] refer to Figure 1 and Figure 4 The reduction motor 200 drives the flip center shaft 600 to drive the rotating turntable 100 to rotate 180 degrees. After rotating to the specified position, the guide rod cylinder pushes the limit block to constrain the cam bearing follower between the limit surfaces. The change process is as follows: Figures 5 to 6 When the turntable 100 needs to be rotated again, the guide rod cylinder drives the limit block to retract to the initial position, and the reduction motor 200 can drive the turntable 100 to rotate.
