Description

  The present invention relates to a packing device for fixing a roll formed by winding a tape around a cylindrical core material, and particularly a roll-shaped dry film resist and dicing that require protection from heat, impact, light, dust, etc. The present invention relates to a functional film packaging device represented by a tape, a copper foil with resin, a heat-resistant insulating film and the like.

  In recent years, the progress of electronic devices has been remarkable, and computers, home appliances, mobile phones, and many other electronic devices are industrially produced in large quantities using printed circuit boards made with precision wiring technology on the order of microns. .

  A dry film resist (hereinafter referred to as “DFR”) used for such a precision printed circuit board has a photosensitive adhesive composition supported on a carrier film such as polyethylene terephthalate (hereinafter referred to as “PET”). Further, it is formed of three layers of a cover film such as a low density polyethylene (hereinafter referred to as “LDPE”) for facilitating the handling of the dust composition and the pressure-sensitive adhesive composition, which is a copolymer of acrylonitrile, butadiene, styrene or These are wound into a long tube such as a blend (hereinafter referred to as “ABS”) and cut into a required length depending on the application.

  In the DFR, slight scratches and uneven thickness in the DFR may greatly affect the product. For this reason, it is necessary to prevent the film roll from coming into contact with a part of the container by its own weight or external force, and causing the film roll to be deformed, damaged or uneven in thickness. Therefore, in the case of DFR, usually, the core material of the film roll is held, and the tape (film) and the container are packed and conveyed so that they are not in contact with each other.

  Conventionally, as an instrument used for packing a roll of a functional film, for example, one described in FIG. 8 or Japanese Patent Application Laid-Open No. 7-149344 has been used. Referring to FIG. 8, the packaging device 103 includes a cylindrical protrusion 102 at the center of a plate surrounded by a normal square outer frame 101 that is slightly larger than the diameter of the film roll 105. In some cases, ribs (not shown) having various shapes are arranged on the back side of the plate surface to be reinforced. In use, the cylindrical projection 102 of the packing device 103 is inserted into the holes at both ends of the core 104 serving as the core material of the film roll 105, and the two packing devices 103 and the core 104 of the functional film roll are bridged. To hold and fix the film roll 105. On top of that, after being packed in a paper cardboard box and packed, it is stored and transported. In FIG. 7, reference numeral 4 denotes a light shielding film, and the DFR 1 and the core 2 are integrally packaged by the cylindrical light shielding film 4.

  However, conventionally, there has been no package suitable for a dry film compatible with a narrow flexible substrate such as TAB (Tape Automated Bonding) and COF (Chip On Film). That is, since the conventional packing body is packed one by one like the roll for printed wiring board use, the number of parts is large, unpacking and packing takes time, and a lot of space is required. Also, in applications such as TAB / COF, which requires a much higher degree of cleanliness than printed wiring board applications, packing with corrugated cardboard that is dusty is difficult. In the conventional technology that requires time for assembly, unpacking, and packing, it is difficult to bring the entire package into the clean room, and the package itself cannot be easily cleaned.

  Therefore, the present invention accommodates a plurality of rolls formed by winding a tape around a cylindrical core material, enables packing and unpacking in a narrow space, and reduces the number of parts to reduce the cost. The purpose is to provide equipment.

In order to solve the above problems, a typical configuration of the present invention is a packing device for fixing a roll formed by winding a tape around a cylindrical core material, and a cross-sectional shape that can be inserted into the core material And a plate having a hole having a shape substantially the same as the cross-sectional shape of the core at a substantially central portion, the core is inserted into the core material of the roll, and the ends of the core are at both ends. By fitting a plate, it is possible to hold the roll so that it cannot be detached from the core, and the core material is configured to be longer than the width of the tape, and the side surface of the tape is connected between the connected rolls. When the core material is configured so as not to contact or the width of the core material is substantially equal to the width of the tape, a ring-shaped sleeve having substantially the same cross-sectional shape as the core material is inserted between the rolls, whereby the tapes Contact Sealed, wherein the tape is a photosensitive dry film resist, the roll is characterized in that it is rotatably supported by Kosudo in a state of being retained. Thereby, the roll of photosensitive dry film resist tape can be held and packed so that the tape and the packing material are not in contact with each other, and the tape is pulled out from the roll and used while the roll is held in the packing device. Is possible .

  Further, the core has a length that is a multiple of the width of the core material, and is capable of holding a plurality of the rolls. Thereby, it becomes possible to hold a plurality of rolls around which a narrow film is wound.

The cross-sectional shape in said core is characterized by a shape that fits the inner diameter of the core material.

  Further, one of the plates fitted to both ends of the core is fixed to the core or is integrally formed with the core. As a result, the rigidity in the packing state is improved, and the packing work can be reduced.

  The plate is provided with at least one straight portion on an outer edge. Thereby, it is possible to prevent the packing device holding the roll from rolling and stably mount it.

  In addition, further comprising a light-shielding sheet, the core has a hollow shape opened at least at one end, the light-shielding sheet covers the core and the plate holding the roll, and ends Can be accommodated in the opening of the core. As a result, the light-shielding sheet that prevents the tape from being exposed to light can be simply and reliably attached, and can be quickly removed.

  Further, the light-shielding sheet has a tube shape in which both ends in the end direction of the core are opened, or a bag shape in which one end is opened. Thereby, the reliability of light shielding can be improved without losing the ease of attachment and removal.

  Further, a plastic box is provided, and the box can accommodate the core and plate holding the roll, or the core and plate holding the roll and covered with the light shielding sheet. Then, the side surface and the top surface can be developed with respect to the bottom surface, and a locking member that can attach and detach the contact piece of the side surface and the top surface is provided. By using a plastic box that is easy to remove dust, it can be easily cleaned and can be deployed in a mounted state, so that the accommodated roll can be easily taken out, and the locking member can be attached and detached for deployment. Thus, it can be stored, recovered and reused in a small volume. Moreover, a hook-and-loop fastener or a snap hook can be suitably used as the locking member.

  The tape is a photosensitive dry film resist. In particular, the present invention can be effectively used in dry film resists.

  According to the present invention, since a plurality of rolls can be packed together in a state where the tape is not in contact with the packing material, it can be packed in a narrow space with respect to the number of rolls, and is required for packing. The number of parts can be reduced. In particular, it becomes possible to efficiently pack a plurality of narrow photosensitive dry films used for manufacturing TAB, COF, and the like.

  Further, since the tape can be pulled out while the roll is held by the packing device, the film can be easily cut out.

  Further, the light can be reliably shielded by a simple packing operation, and the package can be easily cleaned, unpacked, collected and reused.

FIG. 5 is a diagram illustrating another configuration of the instrument, FIG. 5 is a diagram illustrating another configuration of the core and the plate, FIG. 6 is a development view illustrating the configuration of the box, and FIG. 7 is a diagram illustrating a state where the drum is housed in the box. It is a figure to do. Note that the dimensions, numerical values, and member shapes specifically shown in the following embodiments are examples for facilitating understanding, and do not limit the present invention.

  First, an outline of the packaging device will be described, and then the configuration and conditions of each member will be described.

  As shown in FIG. 1, the packing device according to the present invention holds a plurality of rolls 10 formed by winding a tape 11 around a cylindrical core material 12. In this embodiment, the tape 11 is a narrow-width DFR (dry film resist) used for the manufacture of TAB (Tape Automated Bonding), COF (Chip On Film), etc. It is necessary to protect against rubbing. The core material 12 is made of ABS resin. The width of DFR used for manufacturing TAB, COF, etc. is generally 160 mm or less, and the present invention is particularly effective in such a range.

  When packing the roll 10, the core 10 is inserted into the core material 12 of the roll 10 and the holes 22a of the plate 22 are fitted to both ends of the core 21 so that the roll 10 is removed from the core 21. Keep incapable of falling off. The core 21 and the plate 22 that hold the roll 10 are hereinafter referred to as a drum 20.

  Then, as shown in FIG. 2, the drum 20 is covered with a light shielding sheet 30 and accommodated in a box 40. The box 40 is a prefabricated type, assembled when housed, and unfolded when unpacked.

  As shown in FIG. 3A, the core material 12 is configured to be longer than the width of the tape 11, and is configured such that the side surfaces of the tape 11 do not contact each other between the connected rolls 10. When the width of the core material 12 is substantially equal to the width of the tape 11, as shown in FIG. 4, a ring-shaped sleeve 13 having substantially the same cross-sectional shape as the core material 12 is inserted between the rolls 10. The contact between the tapes 11 can be prevented.

  The core 21 is a cylindrical member, and is a hard PE (polyethylene) pipe in this embodiment. The length of the core 21 is configured to be a length that is a multiple of the width of the core material, the thickness of the two plates 22 that are fitted to both ends, and a slight margin. The multiple times are set according to the width of the core material and the number of rolls 10 to be accommodated, but it is preferable to set so as to accommodate and sell an even number of rolls 10. Since a plurality of rolls 10 can be stored in this way, the number of parts can be relatively reduced, the volume can be stored efficiently, and the packaging cost can be reduced. Can do.

  As shown in FIG. 3B, the outer diameter d1 of the core 21 is set smaller than the inner diameter d2 of the core material 12, and the roll 10 is rotatably supported by rubbing while being held. ing. The core 21 is not limited to a cylindrical shape, and may be inserted into the core material 12 of the roll 10 with a small amount of play. Therefore, for example, it may be a polygonal shape such as a triangle, square, or octagon, or a rib structure having a cross-shaped cross section. However, since it is necessary to accommodate the end portion of the light-shielding sheet 30 as will be described later, at least one end portion of the core 21 needs to be an open hollow shape.

  In this embodiment, the plate 22 is made of foamed polypropylene (foaming magnification is 3 times), and is formed by cutting four corners of a square of 4 mm thickness and 180 mm square into an arc shape. The material of the plate 22 is not limited to this, and it is sufficient that the core 21 can be press-fitted or locked. Therefore, an elastic member may be used in the vicinity of the hole 22a even if it is a resin material of another material having elasticity, a hard resin or a metal material, or a snap fit may be formed in the vicinity of the hole 22a of the hard material. The snap-fit means that, for example, a notch is provided in the plate to form a tongue-like elastically deformable portion, and the protrusion provided at the tip of the tongue-like portion and the recess provided in the core 21 are locked. It is composed.

  As for the shape of the plate 22, the four corners may be cut linearly or the four sides of the circle may be cut linearly. Further, the reason why the plate 22 is based on a square is for the purpose of installation stability for the purpose of preventing rolling. For this purpose, it is only necessary to provide at least one straight portion on the outer edge. Accordingly, the plate 22 may be provided with one or more straight portions based on, for example, a circle, or a polygon such as a hexagon or an octagon. Note that the drum 20 needs to be accommodated in the box 40, and preferably has straight portions in four directions in order to efficiently fit in the box 40.

  The hole 22 a of the plate 22 is provided at a substantially central portion of the plate 22. Here, the hole 22a is positioned in all directions from the center of the hole 22a in order to prevent the tape 11 of the roll 10 held when the drum 20 is placed from coming into contact with the placement surface (floor surface). The distance to the edge of the plate 22 needs to be longer than the radius of the roll 10. As shown in FIG. 3B, the inner diameter d3 of the hole 22a is set to be approximately equal to or slightly smaller than the outer diameter d1 of the center core 21, and the center core 21 is fitted into the hole 22a of the plate 22 by press fitting. . As a result, the plate 22 is fixed to the center core 21, the roll 10 can be held so as not to drop off, and the whole can be supported without tilting when the drum 20 is placed. In particular, since it is made of foamed polypropylene as described above, the attachment / detachment work, that is, the work of packing and unpacking is easy due to its elasticity, and a sufficient load resistance can be obtained.

  Here, in order to stably place the drum 20, it is preferable that the linear portions of the plates 22 at both ends have the same phase. Even if the phases do not match, it may be rotated when placed, but it is more preferable if the phases inevitably match. Therefore, for example, as shown in FIG. 5 (a), a notch 21a may be provided in the center core 21, and a protrusion 22b may be provided in a hole 22a of the plate 22 to be fitted to each other to define the phase. However, it should be noted that if the material is foamed polypropylene, the rigidity is not so high, so that if the protrusion is too small, it will be damaged. Further, as shown in FIG. 5B, a flat portion 21b may be provided at the end of the core 21 and a straight portion 22c may be provided in the corresponding hole 22a. Further, as described above, the core 21 does not necessarily need to be a cylinder. Therefore, as shown in FIG. 5C, the cross section of the core 21 is a polygon such as a quadrangle or an octagon, and the corresponding hole 22a is the same shape. It may be a polygon. Thereby, as shown in FIG.5 (b), since the freedom degree of a fitting increases rather than the case where one plane part is provided, a packing operation becomes easy. Here, in order to match the phases of the plates 22 at the left and right ends, it is desirable that the polygonal linear portion of the hole 22a and the linear portion of the outer edge of the plate 22 coincide. For example, if the center core 21 and the hole 22a are triangular, the plate 22 preferably has three straight portions at equal intervals, and if it is an octagon, the plate 22 preferably has eight straight portions.

  In order to attach and detach the roll 10, it is sufficient that one of the plates 22 fitted to both ends of the core 21 can be attached and detached. Therefore, one plate 22 may be fixed to the core 21 by non-detachable adhesion or welding, or may be integrally formed with the core 21. With this configuration, it is possible to reduce the number of parts, improve rigidity, and reduce work processes.

  In the present embodiment, the light-shielding sheet 30 has a tube shape in which both ends in the end direction of the core 21 are open as shown in FIG. 2, and an excess portion at the end as shown in FIG. Is packed in the opening at the end of the core 21 and accommodated. Although it is conceivable to seal the surplus portion by welding or adhesion, the configuration of the present embodiment is preferable in order to reduce packing and unpacking operations. The light-shielding sheet 30 may have a bag shape with one end opened, and the excess portion is similarly packed in the opening of the core 21 and accommodated. That is, the core 21 uses a hollow member in the present embodiment, but may have an opening that can accommodate the light-shielding sheet 30 at the end, and the center may be solid. Further, the material and color of the light shielding sheet 30 is not limited as long as it has light shielding properties, and for example, a black vinyl material made of polyethylene can be suitably used.

  The box 40 is composed of a black low foam plastic sheet in this embodiment. FIG. 6A is an example of a development view of the inner surface of the box 40, and FIG. 6B is an example of a development view of the outer surface of the box 40. As shown in the drawing, the side surface 40b and the top surface 40c can be developed with respect to the bottom surface 40a, and a hook-and-loop fastener 41 is provided as a locking member that can attach and detach the contact pieces of the side surface 40b and the top surface 40c. Thus, by using a plastic box, no dust is generated, and the attached dust can be easily removed by washing, and the entire package can be brought into a clean room. Further, since it can be deployed in a mounted state, packaging is easy, and the accommodated roll 10 can be easily taken out. As the locking member, in addition to the hook-and-loop fastener 41, a snap hook or other existing locking members can be used. By removing and deploying the locking member in this way, it can be easily deployed and flattened, so that the box 40 can be stored in a small volume, and can be easily recovered and reused. It is.

  FIG. 7 is a cross-sectional view showing a state where the drum 20 is stored in the box 40. As shown in the figure, in order to prevent the drum 20 from moving inside the box 40, the inside of the box 40 has a substantially square cross-section, and the distance between the parallel portions of the plates 22 is greater than the interval d4. The distance d5 is set to be slightly smaller. The diameter d6 of the tape 11 of the roll 10 is set so as to be sufficiently smaller than the distance d5 between the straight portions of the plate 22, so that it does not collide with the tape 11 even when the box 40 is bent. Protect.

  Note that the development view of the box 40 is not limited to that shown in FIG. 6, and it is only necessary that the side surface and the top surface can be developed with respect to the bottom surface.
