Description

  The present invention relates to a reel for winding a sheet-like material on which a long sheet-like material is wound.

  For example, these packages that are formed in a continuous band with a plastic film, such as a “diaper package” for packaging paper diapers into a sales form, a “napkin package” for napkins, and a “toilet roll package” for toilet paper (FIG. 4) In a facility that handles the above, the package a is wound around a reel, and the contents such as diapers and napkins are sequentially packed, and the contents are packed while being unwound from the reel and cut into one bag. The product form is sealed and supplied to the market.

  A reel for winding a long sheet-like material such as the above-described strip-shaped package a is a fixed structure that is previously formed to have an internal dimension between flanges corresponding to the width b of the package a that is the object of the reel. Therefore, it is a dedicated product for package a to be handled.

  Therefore, when the type of the package a to be wound is changed and the width b thereof is different, the reel having an internal dimension corresponding to the width b is used. For this reason, it is necessary to prepare reels corresponding to the types of packages a having different widths, and disposal of the reels that have become unnecessary leads to a momentary increase in costs.

  It is also conceivable to adjust the distance between the left and right flanges. For this purpose, the reel winding shaft may be divided and telescopically fitted into a telescopic structure to expand and contract, but according to this, the outer diameter of the outer tube and the inner tube constituting the winding shaft are different. Therefore, a step is formed at the overlap between the outer cylinder and the inner cylinder, and when the package a is wound, a difference in thickness occurs between the left and right, which is not preferable.

  Even if the above points are ignored, it is difficult to fix the gap between the left and right flanges, and a reel with an adjustable gap between the flanges has not been provided. It has been.

  In view of this, the present invention makes it possible to quickly adjust the interval between the left and right flanges in response to the width of the belt-like sheet to be wound, and to change the reel corresponding to the width when changing the sheet-like object. An object of the present invention is to provide a reel for winding a sheet-like material that can be wound to a uniform thickness when the sheet-like material is wound without eliminating the need for new production and increasing the cost. It is.

  As means for solving the above-mentioned problems, the present invention comprises a pair of left and right flange bodies, and these flange bodies have a disk-like flange portion and the same concentrically provided on opposing surfaces of these flange portions. A core having a diameter, a male screw shaft projecting concentrically at the tip of one of the cores, a female screw hole provided at the tip of the other core and into which the male screw shaft is screwed, A lock nut threadedly engaged with the male screw shaft, the male screw shaft is screwed into the female screw hole, the interval between the flange portions is adjusted, and then the lock nut is fastened and fixed. It is in.

  The lock nut has an outer diameter that is not larger than the outer diameter of the core.

  The winding core is formed of a hollow cylindrical body, and a base end thereof is fixed to the flange portion with a screw. The male screw shaft is provided on the tip surface of one winding core, and the female screw hole is provided on the tip portion of the other winding core. It is preferable to provide each of them in terms of weight reduction.

  The interval between the flange portions is preferably adjustable within a range of 80 to 500 mm, and the plate thickness of the flange portion is set to 10 to 15 mm and the outer diameter is set to a range of 800 to 1000 mm.

  As the sheet-like material wound around the reel, it is optimal for a package that is a packaging material such as a diaper, a napkin, and a toilet paper roll, but it is optional to apply to other similar sheet-like materials. is there.

  According to the present invention, the interval between the flange portions of the reel can be adjusted to an interval suitable for the width of the sheet-like material depending on the width of the sheet-like material to be wound. It is not necessary to discard the reels or prepare and procure new reels, which can be very advantageous in terms of cost.

  To adjust the spacing between the flanges, just loosen the lock nut and rotate one flange body relative to the other flange body to adjust the threading depth between the male screw shaft and female screw shaft. The interval can be set, and if the lock nut is tightened after the interval is set, both flange bodies are firmly integrated, and can immediately respond to the winding of the sheet-like material.

  Since the interval adjustment can be completed in a short time of about 20 to 30 seconds, it can be dealt with quickly without affecting the overall work.

  Further, if each winding core is formed of a hollow cylindrical body, the reel itself can be reduced in weight, and handling can be facilitated.

The disassembled perspective view which shows one Embodiment of the reel for sheet-like material winding by this invention. The front view which showed the state which assembled | assembled, (A) showed the state which maximized the space | interval between flange parts, and (B) showed the state which made the minimum the same in cross section. Explanatory drawing which shows the state which wound the sheet-like thing. The partial top view which shows an example of a sheet-like thing.

  FIG. 1 is an exploded perspective view of an embodiment of a reel for sheet-like material winding according to the present invention, and FIGS. 2A and 2B are front views partially showing a working state, and a pair of left and right Flange bodies 1A and 1B are provided. These flange bodies 1A and 1B have disk-like flange portions 2A and 2B, and a concentric hollow cylindrical core 3 is concentrically formed on the opposing surface of one flange portion 2A. It is fixed by screws 4 and 4 and protrudes integrally, and a male screw shaft 5 having a smaller diameter is concentrically protruded from the front end surface of the core 3.

  On the opposite surface of the flange portion 2B of the other flange body 1B, a hollow cylindrical winding core 6 having the same diameter as that of the winding core 3 is fixed by screws 7 and 7 so as to project integrally. A female screw hole 8 in which a female screw into which the male screw shaft 5 is screwed is formed.

  A lock nut 9 is screwed onto the male screw shaft 5, and after the male screw shaft 5 is screwed into the female screw hole 8, the lock nut 9 is rotated to be attached to the front end surface 6 a of the core 6. By fastening so as to be in pressure contact, the interval between the flange portions 2A and 2B of the two flange bodies 1A and 1B is securely maintained firmly.

  The lock nut 9 has the same diameter as or smaller than the outer diameter of the winding cores 3 and 6, and a sheet-like material (package a) as shown in FIG. As shown in FIG. 3, the lock nut 9 does not become an obstacle.

  When the sheet-like material is intended for winding a package a for diapers, napkins, and toilet paper rolls, the interval between the flange portions 2A and 2B can be adjusted within a range of 80 to 500 mm. . The outer diameters of the flange portions 2A and 2B are 800 to 1000 mm, and the plate thickness is 10 to 15 mm. Furthermore, a plate material made of wood, a plate material made of a resin material, or the like can be used for the flange portions 2A and 2B.

  Therefore, when adjusting the flange width, if the lock nut 9 is loosened, the left and right flange bodies 1A and 1B are relatively rotated and rotated in the direction in which the male screw shaft 5 enters, the distance between the flange portions 2A and 2B. The distance between the flange portions 2A and 2B is widened by rotating in the reverse direction.

When the gap between the flange portions 2A and 2B reaches a predetermined width, the left and right flange bodies 1A and 1B can be connected to each other by tightening the lock nut 9 and making thick contact with the end surface 6a of the core 6 on the female screw hole 8 side. It is possible to wind a sheet-like material that is fixed in a stationary state and fits the interval.

  Incidentally, FIG. 2A shows a state where the flange width is the maximum width (distance A between the end faces of the cores 3 and 6), and FIG. 2B shows a state where the flange width is the same as the minimum width (same B). However, in any case, since the cores 3 and 6 of the left and right flange bodies 1A and 1B have the same outer diameter, a step is formed in the sheet-like material wound around the cores 3 and 6 as shown in FIG. It does not occur and can be wound tightly with high density.

  Even if the lock nut 9 exists between the cores 3 and 6, the outer diameter of the lock nut 9 is the same as or smaller than the outer diameter of the cores 3 and 6, so that the sheet-like material is wound. Will not be disturbed.
