[0001]
BACKGROUND OF THE INVENTION
In the present invention, two or more reels used for unwinding a base material (hereinafter simply referred to as “base material”) wound in a coil shape such as a hoop material used in the manufacturing process of an electronic component are connected in series. Multi-line Lee Le The present invention relates to a continuous unwinding device. More specifically, it is possible to continuously unwind a substrate wound on a plurality of reels without interruption. Ream The present invention relates to a continuous unwinding device.
[0002]
[Prior art]
In the manufacturing process of electronic components such as transistors, a long base material called a hoop material is used in order to improve production efficiency and reduce costs. By continuously passing the hoop material through a series of process equipment, each manufacturing process such as chip bonding, wire bonding, resin sealing, etc. can be performed sequentially on the hoop material, and the electronic components are placed on the hoop material. Can be produced continuously and efficiently. In addition, the hoop material is subjected to press working or plating treatment as necessary. These processes are also performed by continuously passing the hoop material through various processing apparatuses installed in the order of the processes.
[0003]
In the continuous manufacturing / processing steps as described above, the hoop material needs to be continuously supplied. If the supply of the hoop material is interrupted for some reason, the process is interrupted and the efficiency is lowered.
[0004]
In general, the hoop material to be used is supplied by sequentially unwinding a coil wound around a reel. Since the length of the hoop material wound around each reel is limited, in order to continuously supply the hoop material, it is necessary to supply the hoop material wound around a plurality of reels without interruption. is there.
[0005]
For example, an automatic connection machine has been devised as a means for continuously supplying a substrate wound around a plurality of reels. This is because immediately after the unwinding from one reel is completed, the starting end of the substrate wound on the next reel at the end of the substrate (starting end when winding on the reel) (winding up on the reel). By automatically connecting the terminal end), the base material can be continuously supplied without interruption.
[0006]
JP-A-8-143231 proposes a multiple reel capable of winding a long base material over a plurality of reels. According to this method, a long base material can be continuously supplied without interruption without increasing the reel diameter.
[0007]
[Problems to be solved by the invention]
However, according to the above automatic connecting machine, a special mechanism for automatically connecting the terminal end and the starting end of the base material is required, and the equipment cost is improved. As a result, the price of products such as electronic parts is increased. Further, for example, when the supply speed is increased, connection reliability is lacking and it is difficult to perform stable continuous operation.
[0008]
Further, according to the multiple reel described in JP-A-8-143231, in order to continuously wind a long base material around a plurality of reels, the reels are transported as a unit. There is a need. As a result, the weight of the entire reel increases, making it difficult to carry the reel. Further, since the reel structure is complicated, the manufacturing cost of the reel increases. Furthermore, compatibility with existing reels and take-up / unwinding devices cannot be maintained, resulting in increased equipment costs.
[0009]
The present invention solves the above-described conventional problems, has a simple mechanism, is low in cost, can maintain compatibility with conventional reels, has excellent reel portability, and ensures connection reliability. , Group An object of the present invention is to provide a continuous unwinding device capable of continuously supplying materials.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention has the following configuration.
[0011]
That is, according to the present invention Continuous unwinding device Is a reel having a core for winding the substrate in a coil shape, and a side plate provided on at least one end of the core so that one end of the substrate abuts. There are two or more in the rotation axis direction, a spacer is disposed between the reels, and the spacer is the same as or protrudes from the outer peripheral end of the side plate, and the base material A guide surface formed on an outer periphery of the spacer, and a base material wound around a reel on one side of the spacer is connected to the protrusion of the spacer and the guide continuous therewith. Along the surface, it is guided in a substantially spiral manner on the reel core on the other side. The reel and the spacer are separable, and the multiple reel is arranged with its rotation axis in the horizontal direction. It is characterized by that.
[0012]
According to the above configuration, since the base material can be guided in a substantially spiral shape along the protruding portion of the spacer and the guide surface formed continuously therewith, the adjacent reel base materials are guided by the spacer. It can be reliably and easily connected on the surface. Thereby, the base material wound by the some reel can be continued. In addition, since the base material is guided to the winding core in a substantially spiral shape, the base material is unlikely to be damaged such as twisting, bending, wrinkling, and single elongation. As a result, the substrate can be unwound and supplied stably and continuously. In addition, a multi-reel can be manufactured with a small number of parts, a simple structure, and low cost. Furthermore, the compatibility with the conventional reel can be maintained, and it can be used by being attached to a conventional winding / unwinding device.
[0013]
In the above configuration, the spacer is not particularly limited as long as the above configuration is satisfied, but the spacer is cylindrical or has a barrel shape with a convex outer peripheral surface, and can be configured to be eccentric with respect to the reel. . In this case, the side plate has an outer radius r. _P The radius of the outermost periphery of the spacer is r _S , Where d is the amount of eccentricity _P ≦ r _S It is preferable to satisfy + d. Further, the radius of the outer peripheral surface of the winding core is r _C The radius of the end of the spacer on the core side is r _S ', Where d is the amount of eccentricity
[0014]
[Expression 1]
| R _C -(R _S '-D) | / r _C ≦ 0.2
[0015]
Is preferably satisfied.
[0016]
As another configuration of the spacer, the planar shape of the spacer viewed from the rotation axis direction may be an oval or an ellipse, and one end portion in the long axis direction may be the protruding portion. .
[0017]
With any of the above configurations, a spacer having a protrusion and a guide surface can be easily realized.
[0018]
Said structure WHEREIN: It is preferable that the said spacer has a notch part for preventing interference with a base material. According to such a preferable configuration, the pitch of the spiral of the guide surface can be reduced, and the tension in the longitudinal direction of the base material can be made substantially uniform in the width direction. The occurrence of damage such as elongation can be further prevented.
[0019]
In the above configuration, it is preferable that the reel and the spacer are separable. According to such a preferable configuration, if a reel that has been used conventionally can be used as a reel, a multiple reel having the above-described characteristics can be easily realized only by newly adding the spacer of the present invention. Further, since each reel can be handled as a unit, the weight of the reel is not increased, and the handling property of the reel does not deteriorate.
[0020]
The multiple reel of the present invention is used by arranging two or more reels each wound with a base material through the spacer and then sequentially connecting the base materials wound on adjacent reels. Is preferred. According to such a preferable configuration, each reel can be handled as one unit until the base materials of adjacent reels are connected to each other, so that the weight of the reel does not increase and the handling property of the reel does not deteriorate. In addition, if a conventionally used reel can be used as the reel, the substrate can be wound around the reel by using a conventional winding device, so that compatibility with the conventional reel can be ensured.
[0021]
Furthermore, in the above configuration, the base material is preferably a hoop material. The hoop material is used as a carrier base material in the manufacturing process of electronic parts and the like that are sequentially processed by arranging various devices in the order of the processes. By applying the present invention to the hoop material, The effect of the above can be exhibited more remarkably, and the production efficiency of electronic parts and the like can be improved.
[0022]
A continuous unwinding device according to the present invention includes the multiple reel described above. According to such a configuration, it is possible to realize a continuous unwinding device having a simple structure, low cost, and ensuring connection reliability.
[0023]

Hereinafter, the present invention will be specifically described with reference to the drawings.
[0024]
(Embodiment 1)

FIG. 1A is a plan view, and FIG. 1B is a cross-sectional view taken along the line II in FIG. is there. FIG. 2 is a schematic perspective view showing a state in which a base material is wound around the reel shown in FIG. 3A and 3B are diagrams showing a schematic configuration of the spacer according to the present embodiment, in which FIG. 3A is a plan view, and FIG. 3B is a cross-sectional view taken along the line II-II in FIG. is there. 4A and 4B are diagrams showing a schematic configuration of a part of the multiple reel according to the present embodiment, in which FIG. 4A is a plan view and FIG. 4B is from the direction of the arrow along the line III-III in FIG. FIG. FIG. 5 is a perspective view of the multiple reel according to the present embodiment shown in FIG.
[0025]
As shown in FIG. 1, the reel 110 according to the present embodiment includes a cylindrical core 111 around which a base material is wound, and a disc-shaped side plate 112 provided at one end of the core 111. . A through hole 113 for inserting a holding member (not shown) is formed at the center of the reel 110. The reel 110 is used by rotating around the central axis 115 of the winding core 111. The disc-shaped side plate 112 has its center on the central axis 115. The core 111 and the side plate 112 may be molded or processed integrally, or may be manufactured separately and then integrated together.
[0026]
Width W of core 111 _C Is appropriately determined according to the width of the substrate to be used. In general, it is preferably about 5 mm larger than the width of the substrate.
[0027]
FIG. 2 is a schematic perspective view showing a state in which the base material 130 is wound around the reel 110 of FIG. In the present embodiment, as shown in FIG. 2, the winding start portion (starting end of the base material 130, but “end” when the base material is unwound, hereinafter, the base material is wound on the reel unless otherwise specified. ("Start end" and "Termination end" are defined assuming the case where the substrate is taken) 131) in a state where 131 is unwound by a predetermined length and one end portion of the base material is in contact with the side plate 112. Wrap on 111. The reason why the start end 131 is pulled out in advance is that when a plurality of reels in FIG. 2 are connected in series, the start end 131 is connected to the end of the base material wound around the adjacent reels.
[0028]
As shown in FIG. 3, the spacer 120 of the present embodiment has a barrel shape in which the outer peripheral surface 121 is convex. Further, a through hole 123 having substantially the same diameter as the through hole 113 formed in the reel 110 of FIG. 1 is formed. At this time, the central axis 125 of the through hole 123 is not the same as the central axis 126 of the outer peripheral surface 121 and is eccentric by a distance d.
[0029]
4 and 5 show the multiple holding according to the present embodiment by inserting the cylindrical holding member 101 into the through hole 113 of the reel 110 of FIG. 1 and the through hole 123 of the spacer 120 of FIG. A part of the state in which the reel is configured is shown. In addition, in order to make an understanding of a structure easy, the figure has shown the state in which the base material is not wound. In actual use, as shown by a two-dot chain line in FIG. 4B, the spacer 120 is used between the necessary number of reels 110 one by one.
[0030]
In the present embodiment, the amount of eccentricity d of the through hole 123 of the spacer 120 is the radius r of the outer periphery of the side plate. _P , The radius of the outermost periphery of the spacer 120 is r _S (R _S <R _P ) (See FIGS. 1 and 3), the following relationship is satisfied.
[0031]
[Expression 2]
r _P ≦ r _S + D
[0032]
By setting the eccentricity d of the through hole 123 in this way, when the reel 110 and the spacer 120 are integrated using the holding member 101, a part 121 ′ of the outer peripheral surface 121 of the spacer is the outer peripheral end of the side plate 112. Or the remaining portion of the outer peripheral surface 121 of the spacer is arranged closer to the center of rotation than the outer peripheral end of the side plate 112. As a result, when the reel 110 is continuously provided, the end of the base material can be connected to the start end of the base material of the adjacent reel on the protruding portion 121 ′ of the outer peripheral surface 121 of the spacer, and the base material on the start end side can be connected. It can be guided without difficulty to the core portion of the reel along the outer peripheral surface of the spacer.
[0033]
FIG. 6 is a schematic perspective view showing a state in which the starting end and the terminal end of the adjacent reel base material are connected on the protruding portion of the outer peripheral surface of the spacer.
[0034]
As shown in FIG. 2, base materials 130a and 130b are wound around the reels 110a and 110b, respectively. The spacers 120 are interposed between the reels 110a and 110b, and the holding member 101 is inserted into the respective through holes to be integrated.
[0035]
In this state, the end 132a of the base material 130a wound around the reel 110a and the start end 131b of the base material 130b wound around the reel 110b are connected by the connecting portion 133 on the protruding portion 121 ′ of the spacer 120. . Thus, according to the present embodiment, the starting end and the terminal end of the base material wound on the adjacent reel are connected on the protruding portion 121 ′ of the spacer that is the same as or protrudes from the outer peripheral end of the side plate of the reel. As a result, connection work can be performed easily and reliably. Further, since the spacer has a barrel shape with a convex outer peripheral surface, the base material is not easily damaged in the vicinity of the protruding portion 121 ′, such as twisting or breaking. Further, since the base material 130b is spirally guided from the connecting portion 133 along the outer peripheral surface of the spacer 120 and guided to the core portion of the reel 110b, the base material is twisted, bent, wrinkled, and fragmented even in this process. There is no damage such as elongation.
[0036]
Further, the radius of the outer peripheral surface of the core 111 of the reel 110 is set to r. _C (Refer to FIG. 1 (B)), the radius of the end of the spacer 120 on the side in contact with the core is r _S ', When the eccentricity is d (see FIG. 3A), | r _C -(R _S '-D) | / r _C Is preferably 0.2 or less, more preferably 0.1 or less, and particularly preferably 0. The above parameter means the degree of the step between the outer peripheral surface of the core 111 and the outer peripheral surface of the spacer 120. When this is increased, the base material is easily broken at the core portion and easily damaged such as wrinkles.
[0037]
The thickness of the spacer 120 depends on the width of the substrate used and the radius r of the spacer. _S It is determined appropriately according to the above. However, if the thickness of the spacer is too thin with respect to the width of the substrate, the end portion of the substrate may come into contact with the wall surface of the side plate 112 and be damaged. On the other hand, if the thickness of the spacer is too large relative to the width of the base material, the spiral pitch of the base material guided spirally becomes large, and the base material may be stretched, wrinkled, bent, etc. .
[0038]
In FIG. 6, the case where two reels are connected in series has been described as an example, but it is of course possible to connect more reels in a similar manner.
[0039]
A specific example of the continuous unwinding apparatus using the multiple reels of this embodiment will be described below with reference to FIG.
[0040]
7A and 7B show a schematic configuration of a continuous hoop material unwinding device, where FIG. 7A is a plan view, FIG. 7B is a cross-sectional view taken along line IV-IV in FIG. ) Is a left side view.
[0041]
In the continuous unwinding apparatus of FIG. 7, the reels 110a, 110b, and 110c of the present embodiment around which the base materials (hoop materials) 130a, 130b, and 130c are wound, and the spacers 120a and 120b of the present embodiment, Alternatingly arranged in the rotation axis direction. A holding plate 158 is separately installed on the side where the side plate of the reel 110a is not provided. These are held by the holding member 110. The holding member 110 is rotationally driven in the direction of the arrow in FIG. 7B by a driving device (not shown), whereby the base material is unwound.
[0042]
The base materials 130a, 130b, and 130c are sequentially connected on the protruding portions of the spacers 120a and 120b as described with reference to FIG.
[0043]
In the present embodiment, the base material is wound around a reel together with a slip sheet. The slip sheet that is unrolled simultaneously with the unwinding of the substrate is wound up by the slip sheet reel 153. The interleaf reel 153 is installed corresponding to each reel 110. The suffixes a, b, and c of the interleaf reel 153 correspond to the suffixes a, b, and c of the reel 110, respectively. Each interleaf reel 153 is supported by a support member 154, and one end of the support member 154 is fixed to the base 151 via a fulcrum 155, so that the interleaf reel 153 is installed so as to be movable around the fulcrum 155. Is done. A tension spring 156 has one end connected to the support member 154 and the other end connected to the base 151. As a result, the interleaf reel 153 is biased onto the surface of the base material 130 on the reel 110. Thus, when the reel 110 rotates and the base material is unwound, the interleaf reel 153 rotates in the direction of the arrow in FIG. 7B due to the frictional force with the base material surface, and the interleaf paper becomes the interleaf reel. It will be rolled up.
[0044]
As described above, according to the continuous unwinding apparatus of FIG. 7, the base material wound on the three reels that are continuously provided can be successively unwound and supplied in the order of 130c, 130b, and 130a.
[0045]
As is clear from the above, according to the present embodiment, the connection work is easily and reliably performed by connecting the starting end and the terminal end of the base material wound on the adjacent reels using the protruding portion of the spacer. Can be performed. And if a base material is guided along the outer peripheral surface of a spacer, a base material will not be damaged.
[0046]
Further, if the number of reels to be connected is adjusted, a substrate having an arbitrary length can be continuously unwound and supplied.
[0047]
Further, since the above operation can be realized with a small number of parts such as reels and spacers, and each with an extremely simple structure, a continuous substrate supply device can be realized at low cost.
[0048]
Furthermore, the reel of the present embodiment comprising a reel and a spacer can be attached to a conventional winding / unwinding device if the outer diameter is appropriately selected, and is compatible with a conventional reel. Can be maintained. For example, when a conventionally used reel has a shape as shown in FIG. 1, a continuous unwinding device can be realized simply by adding a new spacer.
[0049]
Moreover, it can handle in the state shown in FIG. 2 until it connects the adjacent base material. Therefore, the reel can be transported in the same manner as in the past, and the weight does not increase and the reel handling property does not deteriorate.
[0050]
In the present embodiment, an example of a barrel shape having a convex outer peripheral surface as shown in FIG. 3 is shown as a spacer, but the present invention is not limited to this. For example, a cylindrical spacer may be used, and corner portions thereof may be chamfered. In the case of a cylindrical spacer, the above explanation is r _S = R _S 'And it is sufficient.
[0051]
(Embodiment 2)
The present embodiment is different from the first embodiment in that the spacer has a different shape, and the other points are the same as in the first embodiment.
[0052]
8A and 8B are diagrams showing a schematic configuration of the spacer according to the present embodiment, in which FIG. 8A is a perspective view, FIG. 8B is a plan view, and FIG. 8C is a left side view.
[0053]
As shown in FIG. 8B, the planar shape of the spacer 220 of this embodiment has an oval shape in which two semicircular arcs arranged on both sides are connected by two parallel straight lines in the central portion. Yes. At one end of the spacer 220, a through hole 223 for inserting a holding member for holding the spacer 220 is formed. The distance L from the central axis of the through hole 223 to the outer peripheral surface 221 in the longitudinal direction is the radius of the outer periphery of the side plate of the reel that is used simultaneously (r in FIG. 1). _P ) Or longer than this. As a result, the outer peripheral surface on the non-through hole side in the major axis direction is the same as the outer periphery of the side plate of the reel or protrudes from the outer periphery of the side plate, and the base materials of the adjacent reels are connected by the protruding portion Can be guided on the outer peripheral surface of the spacer.
[0054]
As shown in FIG. 8, the spacer of the present embodiment has a notch 228 formed on the protruding portion side of the through hole 223.
[0055]
The operation of the notch 228 will be described with reference to FIG. In FIG. 9, the reel 110 shown in FIG. 1 around which the base material 130 is wound and the spacer 220 shown in FIG. 8 are alternately arranged, and a holding member (not shown) is attached to the through hole (see FIG. 1). In the state where the through holes 113) and the through holes 223 of the spacers 220 are integrated and integrated, and then the starting end and the terminal end of the adjacent base materials are sequentially connected, attention is paid to the pair of reels 110 and the spacers 220 therein. FIG. 6 is a conceptual perspective view showing a guide state of the base material 130. As shown in FIG. 9, the base material 130 is guided in a substantially spiral shape along the outer peripheral surface 221 of the spacer 220 and the outer peripheral surface 229 of the notch, and is adjacent to an unshown side (in FIG. 9, the upper portion of the spacer 220). It is connected to the core part of the base material wound on the arranged reel. Here, if there is no notch 228, it is necessary to increase the helical pitch of the base material, the longitudinal tension of the base material becomes non-uniform in the width direction, and twists, wrinkles, bends, fragments on the base material. Elongation may occur. Thus, the notch 228 reduces the helical pitch by preventing interference between the base material and the spacer when the base material is guided in a substantially spiral shape along the outer peripheral surface 221 of the spacer 220. It makes it easy to easily guide the base material to the core portion of the adjacent reel.
[0056]
The outer peripheral surface 229 of the notch is preferably formed in a cylindrical shape having the same central axis as the through hole 223, and the radius thereof is r. ₁ (See FIG. 8B), | r _C -R ₁ | / R _C Is preferably 0.2 or less, more preferably 0.1 or less, and particularly preferably 0. The above parameters mean the degree of the step between the outer peripheral surface of the core 111 and the outer peripheral surface 229 of the notch, and when this becomes large, the base material is easily broken at the core portion and easily damaged such as wrinkles.
[0057]
In the present embodiment, as illustrated in FIG. 8, the spacer having an oval planar shape is described as an example, but the present invention is not limited to this. For example, the planar shape may be an ellipse as long as it has a projecting portion that projects to the same extent as the outer peripheral edge of the side plate of the reel or a guide surface that guides the substrate. Moreover, the corner | angular part may be chamfered.
[0058]
Except for the above, the present embodiment is the same as that described in the first embodiment, and detailed description thereof is omitted here.
[0059]
In the present invention, the example in which the spacer has a notch has been described using the spacer of the second embodiment, but the same notch can be formed in the same manner as the spacer of FIG. 3 described in the first embodiment. The same effects as described in the second embodiment can be obtained.
[0060]
Further, the spacer of the present invention is not limited to those described in the first and second embodiments. For example, the outer peripheral surface of the spacer described in the first and second embodiments includes a region that is not used for guiding the base material, and the outer peripheral surface of such a region is formed in the same manner as the guide surface of the base material. There is no need. That is, as long as the spacer includes the protrusion of the present invention and the guide surface for guiding the base material, the other shapes are not limited to the above-described embodiment, and can be freely changed.
[0061]
Furthermore, since the spacers described in the first and second embodiments are asymmetric with respect to the rotation axis, there is a risk of causing harmful vibrations during rotation. In such a case, it is preferable to remove vibration associated with rotation by using a well-known balance adjusting means such as adding a weight for adjusting the rotation balance or hollowing out a part of the spacer.
[0062]
In the first and second embodiments, the holding member that integrally holds the reel and the spacer is described as an example of a cylindrical member, but the present invention is not limited to this. For example, in order to maintain compatibility with a conventional reel, it is of course possible to design in consideration of the shape of a holding member used in a conventional winding / unwinding device.
[0063]
The substrate to which the present invention can be applied is not particularly limited as long as it is a coiled substrate that requires continuous unwinding. For example, in addition to the hoop material used in the manufacturing process of the electronic component, it can be applied to a base material made of various metals or resins. Moreover, the connection method of a base material can be suitably changed according to the characteristic of a base material, and well-known connection methods, such as adhesion | attachment and welding, can be used.
[0064]
The material and manufacturing method of the reel and spacer of the present invention are not particularly limited, and can be appropriately selected according to the type of base material. For example, it can be manufactured by injection molding a resin and machining it if necessary or machining a metal.
[0065]
The multiple reel of the present invention can be used for various applications that require continuous unwinding of the substrate, and is not particularly limited. For example, it can be used for a continuous unwinding device for hoop materials used in the manufacturing process of semiconductor devices such as transistors. That is, the coil-shaped hoop material wound around the reel can be used for a continuous unwinding device when unwinding for the press working process for manufacturing the lead frame. Alternatively, the hoop material punched into the lead frame shape in the pressing process can be wound on a reel, and then used for a continuous unwinding apparatus for unwinding for the plating process.
[0066]
【The invention's effect】
According to the multi-reel of the present invention, the base material can be guided in a substantially spiral shape along the protruding portion of the spacer and the guide surface formed continuously therewith. It can be reliably and easily connected on the guide surface of the spacer. Thereby, the base material wound by the some reel can be continued. In addition, since the base material is guided to the winding core in a substantially spiral shape, the base material is unlikely to be damaged such as twisting, bending, wrinkling, and single elongation. As a result, the substrate can be unwound and supplied stably and continuously. In addition, a multi-reel can be manufactured with a small number of parts, a simple structure, and low cost. Furthermore, the compatibility with the conventional reel can be maintained, and it can be used by being attached to a conventional winding / unwinding device.
[0067]
Further, according to the continuous unwinding apparatus of the present invention, it is possible to realize a continuous unwinding apparatus having a simple structure, low cost, and ensuring connection reliability.
