Fig. 2 is a front view illustrating a winding width adjusting apparatus according to one embodiment of the present invention. Fig. 3 is a front view for explaining an operation method of a winding width adjusting apparatus according to an embodiment of the present invention.
Referring to fig. 1 and 2, a winding width adjusting device 100 according to an embodiment of the present invention includes a traverse section 110, a pressing section 120, a position sensor 130, and a bobbin holder 140. The winding width adjusting apparatus 100 according to one embodiment of the present invention is an apparatus that adjusts a winding width of a wire wound around a bobbin 141 coupled to a bobbin bracket 140 when the wire is wound around the bobbin 141. The traverse unit 110, the pressing unit 120, the adjustment unit 130, and the bobbin holder 140 are provided in the main body 10 of the winding width adjustment device 100.
The traverse unit 110 is provided at the upper end side of the main body 10. The traverse unit 110 is capable of moving up and down, and left and right, and thus adjusts the winding width of the thread wound around the bobbin 141. The wire stays at both ends of the bobbin 141 for a relatively longer time than at other portions, and thus the winding thickness at both ends of the bobbin 141 becomes relatively thick. Therefore, in order to prevent such a phenomenon, the present invention raises and lowers the traverse section 110 at a constant cycle. The traverse unit 110 includes a cam support 111, a traverse cam 112, and a cam cylinder 113.
The cam support portion 111 is fixed to the main body 10, and supports the traverse cam 112. The cam supporting portion 111 is formed to protrude from the main body 10 and extend in a horizontal direction. The cam support portion 111 is formed to be longer than the traverse cam 112, and can support the traverse cam 112 that reciprocates in the lateral direction.
The traverse cam 112 is provided in the cam support portion 111 and traverses in the lateral direction. That is, the traverse cam 112 traverses along the longitudinal direction of the cam support portion 111. When the traverse cam 112 reciprocates in the transverse direction, the wire is wound around the bobbin 141 with a predetermined winding width. The traverse cam 112 moves back and forth with a different movement width from the winding width of the thread wound around the bobbin 141. This is because the moving width of the traverse cam 112 is reduced by the winding angle (helix angle), the inertia and tension of the wire, the friction force at the portion in contact with the wire, the free length, and the like in the process of being transmitted to the actual winding width of the wire on the bobbin 141.
The cam cylinder 113 is provided above the cam support 111, and moves the traverse cam 112 up and down. The cam supporting portion 111 is provided with a pair of cam cylinders 113. Further, since the cam cylinders 113 are provided in pairs, the traverse cam 112 can be moved up and down stably even if the length of the traverse cam 112 is increased. Thus, according to the winding width adjusting apparatus 100 of the present invention, the plurality of bobbins 141 are coupled to the bobbin holder 140, so that the multi-terminal winding of the multi-heel cord can be achieved at a single time. Of course, only a single cam cylinder 113 may be provided at the center of the cam support portion 111.
The cam cylinder 113 includes a body 114 provided to the cam support 111, a rod 115 inserted into the body 114, and a link plate 116 coupled to a distal end of the rod 115 and connected to the traverse cam 112. The pressure of the cam cylinder 113 is controlled by a main controller (not shown) provided inside the main body 10. In the cam cylinder 113, a rod 115 is projected from the main body or inserted into the main body 114, and the traverse cam 112 is moved up and down. Such a cam cylinder 113 may be any cylinder selected from a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, and equivalents thereof, but the kind of the cylinder is not limited thereto.
For example, when a set hydraulic pressure or pneumatic pressure or the like is supplied from the main controller to the body 114 of the cam cylinder 113, the rod 115 protrudes from the body 114 or is inserted into the body 114. At this time, the link plate 116 connected to the lever 115 moves upward or downward, and the traverse cam 112 connected to the link plate 116 also moves upward or downward along with the lever 115. Thereby, the distance between the traverse cam 112 and the bobbin 141, that is, the size of the free length is changed, and the winding width of the wire wound around the bobbin 141 is changed.
The pressing part 120 is disposed at the other side of the upper end of the main body 10. That is, the pressing section 120 is provided to face the traverse section 110. The pressing part 120 is vertically movable and guides the thread fed through the traverse 110 to the bobbin 141. The pressing portion 120 exerts a function of pressing the bobbin 141 when the wire is wound around the bobbin, thereby stably winding the wire around the bobbin 141. The pressing portion 120 includes a roller support portion 121, a pressing roller 122, and a roller cylinder 123.
The roller support 121 is fixed to the main body 10 and supports the pressure applying roller 122. The roller support 121 is formed to protrude from the main body 10 and extend in a horizontal direction. That is, the roller support portion 121 is disposed in parallel to and opposite to the cam support portion 111.
The pressing roller 122 is provided at the roller supporting part 121, and presses the bobbin 141 coupled to the bobbin supporter 140 with a certain pressure. The pressing roller 122 contacts the bobbin 141 and rotates together with the bobbin 141 when the bobbin supporter 140 rotates at a predetermined speed.
The roller cylinder 123 is provided above the roller support 121 and can move the pressing roller 122 up and down. The roller support portion 121 is provided with a pair of roller cylinders 123. Further, since the roller cylinders 123 are provided in pairs, the pressure roller 122 can be moved up and down stably even if the length of the pressure roller 122 is increased. Thus, according to the winding width adjusting apparatus 100 of the present invention, the plurality of bobbins 141 can be coupled to the bobbin holder 140, thereby achieving multi-termination of the multi-core wire wound at a time. Of course, only a single roller cylinder 123 may be provided at the center of the roller support 121.
The roller cylinder 123 includes a body 124 provided to the roller support 121, a rod 125 inserted into the body 124, and a connection plate 126 coupled to a distal end of the rod 125 and connected to the pressure roller 122. The pressure of the roller cylinder 123 may be controlled by a main controller (not shown) provided inside the main body 10. The roller cylinder 123 has a rod 125 that protrudes from the body 124 or is inserted into the body 124 so as to be able to move the pressure roller 122 up and down. Such a roller cylinder 123 may be any cylinder selected from a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, and equivalents thereof, but the kind of the cylinder is not limited thereto.
For example, when hydraulic pressure or air pressure or the like is supplied from the main controller to the body 124 of the roller cylinder 123, the rod 125 protrudes from the body or is inserted into the body 124. At this time, the connecting plate 126 connected to the rod 125 moves upward or downward, and the pressing roller 122 connected to the connecting plate 126 also moves upward or downward along with the rod 125. Thereby, the pressure applied to the bobbin 141 by the pressure roller 122 varies. In particular, as the wire is wound around the bobbin 141, the size of the cake becomes larger, and the contact pressure between the bobbin 141 and the pressing roller 122 becomes larger, so that the roller cylinder 123 can move the pressing roller 122 upward according to the thickness of the cake, thereby uniformly adjusting the pressure applied to the bobbin 141 by the pressing roller 122.
The adjusting part 130 is provided to the main body 10. The adjusting portion 130 includes a position adjusting device 131 and a speed adjusting device 132. The position adjusting device 131 detects the position of the traverse cam 112, and controls the operation of the cam cylinder 113. For example, when the position adjusting device 131 generates a signal according to the set free length, the cam cylinder 113 can move the traverse cam 112 up and down. That is, the position adjusting device 131 can adjust the vertical movement range of the traverse cam 112. Such a position adjusting means 131 may be constituted by a proximity sensor. The speed adjusting means 132 may adjust the moving speed of the cam cylinder 113 when the cam cylinder 113 moves up and down by the position adjusting means 131. Such a speed adjusting device 132 may be constituted by a speed regulating valve or an electric motor or the like.
The bobbin bracket 140 is disposed at the bottom of the main body 10 and supports the bobbin 141. Further, a bobbin 141 is coupled to the bobbin supporter 140, and the bobbin 141 is positioned at the bottom of the pressing roller 122. The bobbin supporter 140 is rotated at a predetermined speed by a motor or the like, and the wire is wound around the bobbin 141.
Briefly describing the operation of the winding width adjusting apparatus having the above-described components, the following is provided.
The wire is coupled to the bobbin 141 provided to the bobbin bracket 140, thereby being wound around the bobbin 141. At this time, the thread is wound around the bobbin 141 with a predetermined winding width by traversing the traverse cam 112 of the traverse unit 110. Of course, at this time, the pressing roller 122 presses the bobbin 141 with a certain pressure, so that the wire is tightly wound on the bobbin 141.
On the other hand, when the operation direction of the traverse cam 112 is changed, the time for which the wire stays at both side ends of the bobbin 141 is relatively long, and thus a saddle (saddle) phenomenon occurs, so that the winding thickness of both side ends of the bobbin 141 is relatively thick. To prevent this, in the present invention, the traverse section 110 is raised and lowered at a constant cycle. Accordingly, a spinning cake having an even thickness can be formed on the bobbin 141, so that the thread tension is constant during the unwinding process for producing various cloth materials, thereby smoothly performing the subsequent processes such as dyeing.
As shown in fig. 3, when a predetermined air pressure or hydraulic pressure is supplied to the cam cylinder 113, the rod 115 protrudes from the main body 114, and the link plate 116 and the traverse cam 112 rise. At this time, the moving speed of the cam cylinder 113 is determined by the speed adjusting device 132, and the moving distance is determined by the position adjusting device 131. Further, the cam cylinder 113 operates independently from the roller cylinder 123, so that the pressing part 120 does not move any more even if the traverse cam 112 moves by the cam cylinder 113, and the roller cylinder 123 applies a contact pressure to the pressing roller 122 to press the bobbin 141, thereby uniformly winding the wire on the bobbin 141. Of course, as the wire is wound on the bobbin 141, the roller cylinder 123 may maintain the contact pressure to raise the pressing roller 122.
Further, when the cam cylinder 113 does not move up and down the traverse cam 112, the pressure provided to the cam cylinder 113 is provided by the contact pressure between the bobbin 141 and the pressing roller 122. That is, when the traverse unit 110 does not move up and down, the contact pressure between the bobbin 141 and the pressing roller 122 is adjusted by the sum of the pressure of the cam cylinder 113 and the pressure of the roller cylinder 123. On the other hand, when the traverse unit 110 moves up and down, the pressure of the cam cylinder 113 is changed to a pressure capable of moving the traverse cam 112, and only the traverse cam 112 is moved, and the contact pressure between the bobbin 141 and the pressing roller 122 is adjusted only by the pressure of the roller cylinder 123.
As described above, according to the winding width adjusting apparatus 100 of the present invention, since the cam cylinder and the roller cylinder are independently operated, the coupling between the respective structures is simple, which reduces the occurrence probability of an erroneous operation and also facilitates maintenance.
Further, according to the winding width adjusting apparatus 100 of the present invention, since the cam cylinder 113 and the roller cylinder 123 are provided in a pair, even if the traverse cam 112 and the pressure roller 122 are long in length, they can be moved stably, and thus, the number of ends can be increased.
The above description is only one embodiment for realizing the winding width adjusting apparatus according to the present invention, the present invention is not limited to the embodiment, and any person skilled in the art can variously implement the present invention without departing from the gist of the present invention as claimed in the claims, and these also fall within the technical idea of the present invention.
