Description

A break device of rewinder

The present invention relates to a brake device of a winder, and more particularly to a wire, hose, reel, thread, wire, film, tape, raw materials for tires, etc. to adjust and control the rotational speed of the bogie wheel wound As a result, the quality and reliability of the product can be greatly improved, so that consumers as workers can be planted with a good image.

As is well known, when winding a thin item on a bobbin in a winder, it is necessary to temporarily stop the bobbin or adjust the rotational speed to adjust the tension to check the condition of the item wound on the bobbin.

In addition, since the winding wheel on which the bobbin is installed has a cylindrical shape, it is easily rolled up by inertia when transporting the bobbin that has been completely wound up with the intended item, so it may collide or fall with the transportation means, so pay attention during transportation. in need.

Conventionally, a structure for braking the rotation of a winding wheel in which a bobbin is installed is a pair of clamp members, and opposite brake pads are installed at one end of each clamp member so as to be pivotally coupled around the hinge and the other. One end portion is provided with a pressurizing means which is operated in a direction close to and spaced apart from each other so that the brake pad can be brought into close contact with the winding wheel.

The braking force and the useful life of the brake pads are made and determined effectively by the contact area of the brake lining surface and the wilding wheel. Therefore, in order to achieve a smooth braking effect, the contact surface pressure of the brake pad and the winding wheel becomes very important. If the brake pad is fixed to the clamp member without proper flow as in the conventional structure, the brake pad pivots around the hinge. When it comes in contact with the winding wheel, friction force is concentrated on one side, and thus, a smooth braking effect cannot be exhibited, and abrasion of the brake pad occurs, which causes a shortened life.

In addition, when the brake pad is replaced or wear occurs, the braking distance required for braking is changed. In a conventional structure in which a means for adjusting the braking distance is not provided in the manual hand brake device, the braking distance is dependent on the operator's sense. Done and consumes unnecessary labor.

In order to solve the above problems, Utility Model Registration No. 0383660 (Application No. 2004-00035207) (name: Handbrake unit of winding bobbin) has been filed and registered. That is, the conventional technique can rotate the bearing B, which is fixed to the frame F, as shown in Figs. 1 (a) (b) (c) (d) (e). The fixing bracket 1 is mounted on the fixing bracket 1 which is fixed on the frame F so as to apply a braking force to the winding wheel W of the winding shaft S that is fixed. F) It is fixed by welding or using a fastener (not shown), such as a bolt. The upper part is fixed with a fixed shaft (2), and a stopper (10) is formed on the front surface. The first clamp member 3 and the second clamp member 4 are inserted into the diaphragm 1 or fixed by welding, and a nut 20 is fastened to an upper end thereof so that the first clamp member 3 The clamp member 4 is rotatably fastened. An inner side surface of the first clamp member 3 is provided with an inserting hinge 30 into which the fixed shaft 2 is inserted, and a pressure screw 5 in the center of one side. Pretended square A cylindrical space 32 is formed by centering the axial center of the square female screw 31 so that the first elastic member 6 and the cylinder 7 can be accommodated on the inner side thereof. A receiving portion 33 is formed, and a spherical fixing bolt 34 for fixing the second elastic member 9 is fixed on the upper surface thereof, and a spherical shape into which the brake pad 8 is inserted. The pad groove 35 is formed. The inner side surface of the second clamp member 4 accommodates the hinge portion 40 protruding from the upper and lower surfaces so that the insertion hinge 30 of the first clamp member 3 can be inserted. (40a) is formed, the fixed shaft (2) is inserted, the contact groove 41 is formed on the inner side facing the receiving portion 33 of the first clamp member 3, the cylinder 7 is in contact with the support (41) A spherical pad groove 43 for fixing a spring fixing bolt 42 for installing the second elastic member 9 on the upper surface thereof and an brake pad 8a is inserted on the opposite side thereof. The pressure screw 5 is formed with a male screw 50 which is a square screw, and is fastened to the square female screw 31 of the first clamp member 3 so that one side thereof has a space 32 of the receiving portion 33. The opposite end portion is coupled to the rotary ball 100 from the outside and rotates at the same time when the rotary ball 100 is rotated. The first elastic member 6 is formed in a space defined by the inner diameter of the cylinder 7. Inserted and placed in the space 32 of the receiving portion 33, the one end is supported on the pressing piece 200 in the form of a ring or washer coupled to the pressing screw 5, and the other end is cylinder The cylinder 7 is supported by the inner wall surface of the cylinder 7. The support protrusion 70 is formed at the outer center thereof, and the support protrusion 70 is formed by the elastic force of the first elastic member 6 inserted therein. It is supported by the contact groove 41 of the clamp member 4. The brake pads 8 and 8a have a flat surface in contact with the winding wheel W, and the first and second clamp members 3 and 4 have a flat surface. The surface in contact with the It is formed of spherical surfaces 80 and 80a that coincide with spherical surfaces formed by the grooves 35 and 43. The pads 8 and 8a in spherical contact with the first and second clamp members 3 and 4 are formed of a fourth elastic member. The upper elastic portion 301 and the lower coil portion 302 are connected by the vertical connecting portion 303. The fourth elastic member 300, 300a has an even contact surface pressure on the winding wheel W. Each opposite end portion 304, 304a is supported on the upper and lower surfaces of the brake pads 8, 8a, respectively, so that the brake pads 8, 8a are mounted on the first and second clamp members 3, 4, respectively. The rotary ball 100 is composed of the boss 101 and the handle 102 is coupled to the pressure screw (5) is coupled to the pressure screw (5), and the separation and coupling by the braking distance control means in the coupled state The braking distance adjusting means includes a protrusion 51 formed on an outer circumferential surface at one end of the pressurizing screw 5 and a protrusion 104 formed on an inner circumferential surface of the boss 101 and coupled to the protrusion 51. Meeting by The boss 101 of the sphere 100 is slidable at the end of the pressurized screw 5 and formed by the high information bolt 105 fixed to the end of the pressurized screw 5 and the high information bolt 105. Placed in the inner space of the boss 101, one end is supported by the boss 101, the other end is made of a third elastic member 103 supported by the high information bolt 105. The axial space inside the boss 101 on which the 103 is placed compresses the third elastic member 103 in a state where the protrusion 104 of the boss 101 is fully engaged with the protrusion 51 of the pressurizing screw 5. While forming a sufficient space that can be completely disengaged from the projection (51). Therefore, the rotary ball (100) by holding the boss 101 by hand and pulled in the outer axial direction, the third elastic member 103 is compressed, the boss (101) The protrusion 104 of the C) is disengaged from the protrusion 51 of the pressurizing screw 5 so as to be able to idle by itself without rotating the pressurizing screw 5. When the rotary ball 100 is rotated at an arbitrary angle and the rotary ball 100 is released, the rotary ball 100 is pushed in by the repulsive force of the third elastic member 103 that accumulates the compressed elastic force. The projection 104 of 101 is again coupled to the projection 51 of the pressurizing screw 5 so that the pressurizing screw 5 can be rotated. The braking force with respect to the winding wheel W is generated by rotating the knob 102. The rotation of the handle 102 rotates from an arbitrary position, for example, from the position of the imaginary line B, to the range reaching the stopper 10 as shown in FIG. When the rotary hole 100 rotates in this manner, the pressure screw 5 coupled to the protrusion 104 of the boss 101 rotates. The rotating pressure screw 5 is rotated by the first clamp member 3. The female thread 31 is guided to the inside of the cylinder 7 so that the pressing piece 200 compresses the first elastic member 6, and this compression force is The cylinder 7 is pushed, and the support protrusion 70 of the cylinder 7 pushes the second clamp member 4. At this time, the first clamp member 3 and the second clamp member 4 are fixed shaft 2. The second elastic member 9 fixed to the fixing bolts 34 and 42 while turning in the direction away from the center accumulates the pulling force, and the opposite ends of the brake pads 8 and 8a are narrowly spaced apart. The lower brake pads 8 and 8a come into contact with the winding wheel W to exert a braking force. The spherical surfaces of the first clamp member 3 and the second clamp member 4 are supported by the fourth elastic member 300 and 300a. The brake pads 8 and 8a, which are in contact with (80, 80a), are brought into contact with the winding wheel W while being properly flown by the spherical surfaces 80 and 80a. Then, when the handle 102 is rotated in the reverse direction, the pressure screw (5) exits from the square female screw (31) of the first clamp member (3) while rotating slowly outward, and the first clamp member (3) by the elastic force of the first elastic member (6) and the second elastic member (9) Waze 2 The clamping member 4 is rotated to the initial position to release the braking force of the brake pads 8 and 8a. When the device is used for a long time, the brake pads 8 and 8a are inevitably worn and the rotor 100 is moved as much. The greater the range of the angle of rotation, the longer the distance the cylinder 7 pushes the second clamp member 4 can exhibit a smooth braking effect. The angle of rotation of the rotary ball 100 is the boss (101) as described above. This can be done by changing the position where it is re-engaged to the pressure screw 5 by pulling it. In other words, as shown in 1d, when the handle 102 reaches the stopper 10 at an arbitrary position, the angle θ is large. This is when the pads 8 and 8a are worn to a great extent and require a lot of movement. As described above, the first clamp member 3 and the second clamp member 4 are in spherical contact with the brake pad to maintain even contact pressure on the flat surface, thereby preventing the wear of the brake pad from uneven wear and exerting an accurate braking force. By using the braking distance adjusting means, the angle of operation of the turning tool can be adjusted according to the degree of wear of the brake pad. However, the above conventional technology also has many problems such as the following. That is, a large problem arises that the rotational speed cannot be controlled when one clamp member is not operated because a pair of clamp members are in contact with both sides of the winding wheel at the same time. In addition, the conventional technology has a problem in that the rotation speed cannot be properly adjusted according to the type and the material of the winding wheel because the brake pad is not stretched or reduced. In addition, the conventional technology has been pointed out as a problem that the operation of the brake device causes the deterioration of the work efficiency because the operator directly grabs and operates. In addition, the above-mentioned conventional techniques are very complicated, resulting in a large problem that leads to a decrease in productivity and a rise in manufacturing cost.

The present invention has been made in order to solve the problems of the prior art as described above, and to adjust the rotational speed of the bogie wheel while selectively contacting or non-contacting the brake operating portion and the outer peripheral surface of the bogie wheel to selectively operate the brake back and forth The first purpose is to provide a brake for controlling, and the second purpose is to adjust the rotational speed of the bogie wheel in which wires, hoses, reels, seals, wires, films, tapes, raw materials for tires, etc. are wound by the above technical configuration. In particular, the third purpose is that any one of the pair of clamp members does not operate as in the prior art and thus cannot control the rotational speed because one pad contacts the outer circumferential surface of the bogie wheel. The fourth purpose is to ensure that the pad is made of an elastic material, urethane. Even if the type and material of the bogie wheel are different in the door, it can be closely adhered to it so that the rotational force can be adjusted.The fifth purpose is that the cylinder is automatically operated by the operator to operate the pusher operation mechanism. In addition to eliminating the inconvenience of closing the clamp member at once, it is possible to improve the working efficiency accordingly. The sixth object is to simply construct the brake device structurally to improve productivity and reduce manufacturing costs. The seventh object of the present invention is to provide a brake device of a take-up machine that can significantly improve the quality and reliability of a product due to the above-described effects, so that consumers as workers can plant a good image.

As described in detail above, the present invention includes a brake for adjusting and controlling the rotational speed of the bogie wheel while selectively contacting or non-contacting the brake operating portion for selectively operating the brake forward and backward.

The present invention is to enable to control and control the rotational speed of the bogie wheel wound around the wire, hose, reel, thread, wire, film, tape, raw materials for the tire by the above technical configuration.

In particular, the present invention, because one of the pads to contact the outer peripheral surface of the bogie wheel will not be able to operate any one of the pair of clamp members as in the prior art to solve the problem that can not control the rotation speed at a glance.

In addition, since the pad is formed of a stretchable urethane, the pad may be properly adhered to adjust the rotational force even when the type and material of the wheel are different.

In addition, since the cylinder automatically operates the operation of the pusher operation tool applied to the present invention, it is possible to eliminate the inconvenience of the operator holding the handle and operate the clamp member at a time as well as to improve the work efficiency accordingly. I would have to.

3 is a cross-sectional view showing a state in which the brake device of the winder applied to the present invention does not contact the outer circumferential surface of the bogie wheel 178, and FIG. 4 is a bogie wheel of the winder applied to the present invention. A cross-sectional view showing a state of contacting the outer circumferential surface of 178 will be described in more detail below.

As shown in FIG. 3, since the brake 170a is not in contact with the bogie wheel 178, the bogie wheel 178 may naturally rotate, and the pusher operation of the brake operating unit 110a in this state. The sphere 130 is located in the reversed state by the repulsive force of the second spring (141).

And the locking projection 153 is located in the locking hole 162, the pressing jaw 152 is caught on one end of the guide locking hole 161.

When the rotation speed of the balance wheel 178 is to be controlled and controlled in the above state, the first driving cylinder 180 is first moved forward.

Then, the pusher operating port 130 provided in the housing 111 moves forward along the slide hole 112, and the bush 125 and the tip thereof assembled at the front end of the pusher operating port 130 are installed. The brake 170 is fixedly installed in the forward movement together so that the pad 175 is in contact with the outer peripheral surface of the balance wheel 178 to adjust and control the rotational force.

In addition, at this time, the locking protrusion 153 located in the locking hole 162 of FIG. 3 is located in the guide locking hole 161 of FIG. 4, and the pressing locking jaw 152 is moved from one side of the guide locking hole 161 to the other side. Will move.

In the operation process, the locking piece 150 is rotated about the hinge shaft 151, and the first spring 140 is pressed while the locking piece 150 moves forward, and then the locking protrusion 153 is rotated. When inserted into the guide locking hole 161 is opened and returned to the original, and the first spring 140 is separated from the outside in the process of stretching operation by the projection 132 provided in the working space 131. It provides the effect of preventing.

In addition, when the pusher operating port 130 moves forward, the second spring 141 is compressed by the slide hole 112, and the stepped portion 133 may be easily compressed and unrolled by the second spring 141. Will be supported.

In addition, when the pusher operating port 130 is moved forward by the pressure is compressed to the third spring 142 by a predetermined interval is of course the forward operation.

The brake 170a is moved forward by the driving of the brake operation unit 110a as described above, and the guide plate 173 provided at the upper end of the pad bracket 170 has a housing 111 and a cap plate 120. It will operate forward and backward at the top.

In addition, since the pad 175 forward-moving as described above is in close contact with the outer circumferential surface of the balance wheel 178, the rotation force of the balance wheel 178 is controlled and controlled, and the material of the pad 175 is made of urethane. Because it is made to be able to elastically contact the outer circumferential surface of the balance wheel 178, and also because the incision groove 176 is formed in the pad 175 to increase the surface contact while being slightly pressed in contact with the balance wheel 178.

You will.

In particular, the brake 170a applied to the present invention is installed to be inclined at about 50 to 54 ° so that the pad 175 abuts on the outer circumferential surface of the bogie wheel 178, which is in the case where the inclination angle is 50 ° or less. Since 175 is too close to the balance wheel 178, there is a problem that hinders the rotational force of the balance wheel 178, and when the inclination angle is 54 degrees or more, the pad 175 is formed on the bottom of the balance wheel 178. Since there is a problem that can not control the rotational force because it is in close contact, the inclination angle of the brake (170a) is preferably made of 50 ~ 54 °.

When the rotational force of the balance wheel 178 is controlled by the operation of the brake 170a of FIG. 4 as described above, the second driving cylinder 181 is operated to return to the original position as shown in FIG. 3. Is spaced apart from the balance wheel 178.

That is, when the second driving cylinder 181 is lowered and the pressing catch jaw 152 is pressed, the locking piece 150 is rotated about the rotation shaft 151, but the first spring 140 is compressed and locked. The protrusion 153 is separated from the lower portion of the guide locking hole 161.

When the state as described above, the pusher operating port 130 is returned to the original position by the repulsive force of the second spring 141 that has been compressed, but the locking protrusion 153 is in close contact with the bottom surface of the plate 160 When the reverse position is located in the locking hole 162 is inserted into the locking hole 162 by the repulsive force of the first spring 140 to eventually support the pusher operating port 130 is no longer backward.
