Description

The present invention relates to a winder of a coil winder.

  Conventionally, with respect to the winder of the coil winder, the three parts are integrally supported by being sandwiched and supported by a rotary pressure contact body and a torque adjusting pressure contact body fixed to the rotary pressure contact body from both sides of the winding plate. In addition, there is known a structure in which the rotary pressure contact body is attached to a drive shaft so that the winding plate can perform slip rotation when the three components rotate integrally (see, for example, Patent Document 1).

  Further, a winding plate is sandwiched between a rotary plate and a pressure contact plate set loosely on the rotary plate via a galling prevention slip body and a slip pressure adjusting body, and the rotary plate is attached to a drive shaft. The thing which enabled it to maintain the smoothness of a press-contact part and a friction part by a dry type is also disclosed (for example, refer patent document 2).

Japanese Examined Patent Publication No. 2-62085 Japanese Patent No. 2961601

  However, in the invention described in Patent Document 1, since lubrication oil is injected into the pressure contact portion and the friction portion with each component portion to maintain the smooth operation, the oil component easily adheres to the product coil. Since the drive shaft is tightly fitted in the key groove of the rotary pressure contact body, so-called galling and abrasion phenomenon due to friction occurs.

  Further, in the invention described in Patent Document 2, although it is a dry type that does not use a lubricating oil, in reality, a galling or abrasion phenomenon occurs in the pressure contact portion and the friction portion in the same manner as described above. It must be injected.

  In this way, in order to apply the product coil produced by galling with oil attached to so-called high-tech products with high precision and high performance, the attached oil content removal process and the entire device are physically performed every time or over time.・ Work such as mechanical repair, adjustment, maintenance, and parts replacement must be performed.

  In the present invention, the above-mentioned problems are caused by the fact that the load and pressure of the winder due to coil winding are applied as concentrated stress to the drive shaft, so that a high quality product coil can be produced without the need for lubricating oil. It is an object of the present invention to provide a winder that can be applied mainly to so-called high-tech products.

  Thus, the gist of the present invention to solve the above-mentioned problems and achieve the object is to insert the disk body into the drive shaft and to project freely on the outer peripheral surface of the disk body. A winding disk is fitted to a plurality of rotating rollers, and a pressure contact plate that holds and supports both side surfaces of the winding disk is inserted through a flat portion formed in the axial direction of the drive shaft, and , A winding machine for a coil winding device set on the drive shaft.

  According to the configuration of the present invention, when the drive shaft is rotated, the disc body / pressure contact plate and the winding disc rotate in the same direction and at the same speed according to the drive shaft.

  Then, as the winding disk winds the product coil while being restrained by the separator disk, a load, stress, or the like is applied to the wound disk. However, since the winding disk is always fitted to a plurality of rotating rollers, this load and the like are received by being distributed equally to the plurality of rotating rollers. That is, not all of the load applied to the take-up disk is applied to the disk body, but is distributed evenly according to the number of rotating rollers that are always fitted.

  As described above, the dispersed load or the like is transmitted to the drive shaft via the disk body and applied thereto, but no slip occurs between the drive shaft and the disk body. At this time, since the side pressure by the pressure contact plate is simultaneously applied to the winding disk, tension is generated in the product coil in the winding process.

  When the tension of the product coil becomes larger than the frictional force with the pressure contact plate supporting both sides of the winding disc, the slipping surface is slipped, and the friction between the winding disc and the rotating roller is caused by the roller friction. As a result, the rotation of the drive shaft is faster than the rotation of the winding disc, and the product coil can be smoothly wound without causing galling between the disc body and the drive shaft and without using lubricating oil. it can. In addition, if the thickness of the product coil is thick, the slip between the winding disk and the pressure contact plate increases, and the side pressure can be increased as appropriate by the action of a cylinder or a spring by air pressure or hydraulic pressure.

  According to the present invention, the concentrated load can be smoothly dispersed by fitting the take-up disk to the unique mechanical configuration, in particular, a plurality of rotating rollers protruding from the outer peripheral surface of the disk body, Since no galling phenomenon occurs between the disk and the drive shaft, no lubricating oil is required.

  Therefore, since it is a dry type, there is no room for the lubricant to adhere to the product coil in the winding process from the split division, and a high-quality product coil can be provided and can be widely applied to high-tech products in general.

  In addition, the caulking phenomenon does not occur, and since it is a dry type, the maintenance is simple and the maintenance cost can be reduced, and the mechanical device has a long service life and exhibits a unique effect in which stable operation can be expected over a long period of time.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 is an explanatory longitudinal sectional front view of the main body in the present invention, FIG. 2 is a side view of the same, and FIG. 3 is an explanatory longitudinal sectional view of one embodiment of the present invention.

  In the figure, reference numeral 1 denotes a drive shaft in which a flat portion 2 is formed in the axial direction. The disk body 3 is formed by fixing a disk-shaped lid body 5 with a stopper 6 to a convex base 4 obtained by cutting a circumferential surface of a thick disk into a bowl shape, thereby forming a circumferential groove 7. . The circumferential groove 7 is provided with a rotating roller 9 that protrudes from the circumferential groove 7 via a roller shaft 8 set at equal intervals.

  The disc body 3 configured as described above has a hole 10 drilled in the center in advance in the drive shaft 1 and a winding disc 11 fitted to a rotating roller 9 protruding from the circumferential groove 7. In addition, the pressure plates 12 and 13 that sandwich the both side surfaces of the winding disc 11 are inserted into the flat portion 2 of the drive shaft 1. Reference numerals 14 and 15 denote separator disks set on the upper part of the winding disc 11.

  FIG. 3 shows a multi-strand coil winding device in which five of the main body 16 having the above-described configuration is set as the drive shaft 1.

  That is, a fixed base 17 is fixed to one end of the drive shaft 1 with a bolt 18, and a stopper 19, five main bodies 16 and a pressing plate 20 are sequentially inserted into the drive shaft 1, and at the other end of the drive shaft 1. A multi-strip coil equal winding device provided with a pressing machine 21 is configured. The frictional force of the pressure plates 12 and 13 is determined each time by adjusting the pressure by air pressure or hydraulic pressure introduced from the hole 22 of the pressing machine 21.

  According to this apparatus, the product coil 23 divided into small parts can be wound at the same time with constant and uniform rigidity with the above-mentioned effects. In addition, the code | symbol 24 is the insertion groove | channel of the coil end provided in the winding disc 11, and 25 is the hanging hook hole for conveyance movement.
