Description

The present invention relates to a blade contact adjustment sheet holder used with a punching die substrate, and a blade contact adjustment sheet holding method.

In order to manufacture a packaging box using a material sheet such as a paperboard or a cardboard sheet, a plate (blank) developed into a shape required to form the packaging box is required. A die punching device such as a lithographic punching machine is used for producing this blank. The die-cutting device has a punching die in which a plurality of punching blades and ruled pressing blades are implanted on the plate surface of the die substrate. The layout of the punching die can be changed according to the dimensions of the packaging box to be manufactured.

In the punching die, there is a portion where the punching blade cannot sufficiently cut the material sheet (a portion where the blade contact is bad). Further, repeated use of the punching die may deteriorate the blade contact. Therefore, in order to punch a blank without trouble, it is necessary to frequently adjust the blade contact of the punching die.

A blade contact adjusting sheet on which a layout drawing of the punching blades is drawn is used for adjusting the blade contact of the punching die. Here, in some cases, after punching a blank with a punching die whose blade contact has been adjusted, the blanking of the blank needs to be adjusted again in order to punch the blank again. Therefore, it is desirable for convenience to store the blade contact adjustment sheet together with the punching die.

BACKGROUND ART Conventionally, as a storage tool for storing a blade contact adjustment sheet, a blade contact adjustment sheet storage tool attached to one side of a punching die has been known (see, for example, Patent Document 1). The blade contact adjustment sheet storage device of Patent Document 1 is for inserting and removing the blade contact adjustment sheet in a state of being wound inside the storage portion through openings formed on both side surfaces of the cylindrical storage portion.

The blade contact adjustment sheet corresponds to the punching die, and the tool for accommodating the blade contact adjusting sheet is usually configured so that the blade contact adjusting sheet can be stored together with the corresponding punching die. However, since the rolled diameter of the blade-contact adjusting sheet in the rolled state tries to restore to its original shape when the restraint is released, the winding diameter increases, so that the blade-contact adjusting sheet is stored in the container for adjusting blade-contact adjusting sheet of Patent Document 1. Then, when the blade contact adjusting sheet is put into the storage part and the hand is released, the diameter of the blade contact adjusting sheet expands and comes into contact with the inner wall of the storage part. As a result, there is a problem that resistance is generated between the blade contact adjusting sheet and the inner wall of the storage portion, making it difficult to take the blade contact adjusting sheet in and out. This problem becomes more apparent when the punching die is large because the number of turns of the blade-contact adjusting sheet increases as the size of the blade-contact adjusting sheet increases.

The blade contact adjustment sheet holder 100 is made of a material that is elastically deformable to some extent in consideration of the detachability with respect to the mold substrate 11 and the ease with which the blade contact adjustment sheet 1 is taken in and out, while having sufficient strength. preferable. Examples of such a material include metals such as aluminum alloy, steel and stainless steel, and synthetic resins such as polystyrene, polypropylene, polyethylene and ABS resin.

<Mounting part>
The blade contact adjustment sheet holder 100 is mounted around the die substrate 11 of the punching die 10 via the attachment portion 110.

As shown in FIGS. 2 and 3B, the mounting portion 110 includes one side piece 111 and the other side piece 112 that sandwich the mold substrate 11. In the present embodiment, the upper piece of the mounting portion 110 is the one-side piece 111 and the lower piece is the other-side piece 112, but the lower piece is the one-side piece. The upper piece may be the other side piece. As shown in FIG. 2, the configuration in which the die substrate 11 is sandwiched between the one side piece 111 and the other side piece 112 is preferable because the blade contact adjustment sheet holder 100 can be easily attached to the die substrate 11. ..

As shown in FIG. 2, the one-sided piece 111 has an abutting portion 111 a that abuts the die substrate 11, and a connecting portion 111 b that connects the abutting portion 111 a and the holding portion 150. Here, the connecting portion 111b is inclined in a direction away from the other side piece 112 (from the lower side to the upper side) in the direction from the contact portion 111a to the holding portion 150 (direction from the back surface to the front surface). It is preferable. With such a configuration, even if the die substrate 11 is slightly thick, the contact portion 111a is elastically deformed, so that the contact portion 111a is in contact with the plate surface of the die substrate 11. The mold substrate 11 can be held, and the one side piece 111 and the other side piece 112 can cooperate to hold the mold substrate 11. In this way, it is possible to prevent the blade contact adjustment sheet holder 100 from coming off the mold substrate 11.

As shown in FIGS. 2 and 4(e), it is preferable that the contact portion 111a has a convex portion 115. As shown in FIG. 5, this convex portion 115 engages with the concave portion 15 provided on the upper plate surface of the mold substrate 11. In the conventional product, the convex portion was provided on the linear upper portion, but when the mold substrate 11 is slightly thick, such a convex portion causes the upper portion to elastically move upward. There is a risk of deformation and slipping out of the concave portion 15 of the mold substrate 11. On the other hand, in the present embodiment, as shown in FIG. 5 (a) and (b), not only the type substrate 11 having a common thickness t _1, a mold having a thick plate thickness t ₂ than the plate thickness t ₁ Even in the case of the substrate 11, the contact portion 111 a can maintain the contact state with the plate surface of the mold substrate 11, so that the convex portion 115 does not come off from the concave portion 15 provided in the mold substrate 11. Therefore, it is possible to prevent the blade contact adjustment sheet holder 100 from coming off from the mold substrate 11.

Further, as shown in FIG. 5C, a convex portion 116 that engages with the concave portion 16 provided on the lower plate surface of the mold substrate 11 may be provided on the other side piece 112. By providing the protrusions 116 in addition to the protrusions 115, the die substrate 11 is firmly sandwiched from the up-down direction, and thus it is possible to reliably prevent the blade contact adjustment sheet holder 100 from coming off the die substrate 11. it can.

Further, as shown in FIG. 5(c), the convex portion 115 provided on the contact portion 111a and the convex portion 116 provided on the other side piece 112 have lower convexity from the front side toward the rear side. It may be inclined so that. As a result, when the blade contact adjustment sheet holder 100 is mounted on the mold substrate 11, the portions where the protrusions 115 and 116 have low protrusions are first formed on the upper and lower plate surfaces of the mold substrate 11. Contact. Subsequently, when the blade contact adjustment sheet holder 100 is slid, the connection portion 111b and the other side piece 112 are gradually elastically deformed along the inclination of the protrusion 115 and the protrusion 116, and the blade contact adjustment sheet holder 100. Can be smoothly mounted on the mold substrate 11. Finally, the raised portions of the convex portions 115 and the convex portions 116 are engaged with the concave portions 15 and the concave portions 16, respectively, and it is possible to reliably prevent the blade contact adjustment sheet holder 100 from coming off the mold substrate 11. it can.

As shown in FIG. 5, the one-sided piece 111 (abutting portion 111a) may have a reversion portion 117 at its front end in the back surface direction. The reversion part 117 inclines upward toward the back direction. By having the reversion part 117, as shown in FIGS. 5B and 5C, even if the mold substrate 11 is slightly thick, the mold substrate 11 is held along the reversion part 117. As a result, the one side piece 111 is elastically deformed upward, and the blade contact adjustment sheet holder 100 is easily mounted.

As shown in FIG. 4C, the one side piece 111 is preferably divided into a plurality of pieces, and a slit 118 is formed between the pieces. However, the invention is not limited to this, and the entire one side piece 111 may be integrally formed. The convex portion 115 can be provided on one or a plurality of pieces. When the blade contact adjustment sheet holder 100 is mounted on the mold substrate 11, the convex portion 115 interferes with the plate surface of the mold substrate 11 and the contact portion 111a is lifted up. At this time, since the force of lifting to the upper side acts only on the piece having the convex portion 115, the connecting portion 111b is easily elastically deformed, and the mounting is facilitated. Further, when the blade contact adjustment sheet holder 100 is removed from the mold substrate 11, in order to pull out the convex portion 115 from the concave portion 15, only the piece having the convex portion 115 needs to be lifted up, which facilitates the removal. ..

As shown in FIG. 4C, when the one side piece 111 is divided into a plurality of pieces, the slits 118 between the pieces are narrow slits 118a formed between the connecting portions 111b of the pieces. And a wide slit 118b formed between the contact portions 111a of each piece. In addition, when it has the reversion part 117, the slit 118 formed between the reversion parts 117 of each piece is a wide slit 118b. By providing the wide slit 118b, when removing the blade contact adjustment sheet holder 100 from the mold substrate 11, a tool or a fingertip is hung between the contact portion 111a and the plate surface of the mold substrate 11 via the wide slit 118b. Therefore, it becomes easy to lift the one side piece 111 upward and pull out the convex portion 115 from the concave portion 15.

As shown in FIG. 4C, the other-side piece 112 is formed integrally with the other-side piece 112, but is not limited to this, and the other-side piece 112 is divided into a plurality of pieces. You may. By dividing the other side piece 112, the force of the other side piece 112 to be lifted downward when the blade contact adjustment sheet holder 100 is mounted on the mold substrate 11 acts only on the piece having the convex portion 116. Therefore, the mounting becomes easy. Further, even when the blade contact adjustment sheet holder 100 is removed from the mold substrate 11, in order to pull out the convex portion 116 from the concave portion 16, it is sufficient to lift the piece having the convex portion 116 downward, which facilitates the removal. ..

<Holding part>
The holding unit 150 holds the blade contact adjustment sheet 1 in a rolled state. As shown in FIGS. 2 and 3, on the front surface of the holding portion 150 (the surface opposite to the mounting portion 110 and distal from the end of the mold substrate 11), the blade contact adjustment sheet in a rolled state. An opening portion 155 is formed so that 1 can be taken in and out from the outside of the mold substrate 11.

More specifically, as shown in FIG. 2, the holding part 150 includes a holding part back part 150a, a holding part upper part 150b protruding from the upper part of the holding part back part 150a toward the front, and a lower part of the holding part back part 150a from the front side. And a holding portion lower portion 150c that projects toward. Lateral opening portions 156 are formed on the left and right side portions of the holding portion 150. The side open part 156 and the open part 155 on the front surface of the holding part 150 form an open part continuous in three directions.

Since the holding part upper part 150b and the holding part lower part 150c are connected through the holding part back part 150a, the holding part upper part 150b and the holding part lower part 150c are vertically moved with the connection point with the holding part back part 150a as a fulcrum. It is elastically deformable. By this elastic deformation, the holding unit 150 can hold a plurality of types of blade contact adjustment sheets 1 having different sizes. Therefore, even the blade contact adjustment sheet 1 having a large number of windings and a large winding diameter can be held.

6A and 6B are cross-sectional views showing states before and after the blade contact adjustment sheet holder 100 according to the embodiment of the present invention holds the blade contact adjustment sheet 1, and FIG. 6A shows the blade contact adjustment sheet holder 100. FIG. 3B is a cross-sectional view before holding the blade contact adjustment sheet 1, and FIG. 6B is a sectional view after the blade contact adjustment sheet holder 100 holds the blade contact adjustment sheet 1. As shown in FIG. 6A, since the blade contact adjustment sheet 1 in the wound state is maintained in a restrained state by being gripped by an operator, the winding diameter D of the blade contact adjustment sheet 1 is maintained. ₁ is substantially the same as or slightly smaller than the vertical width of the opening 155. In this state, the blade contact adjustment sheet 1 can be easily inserted into the holding portion 150 via the opening portion 155. That is, as shown by arrow A, when the blade contact adjustment sheet 1 is slid from the opening 155 on the front surface of the holder 150 to the holder 150, the blade contact adjustment sheet 1 changes from the winding diameter D ₁ to the winding diameter D ₂ . It moves to the inside of the holding unit 150 before the diameter is increased. At this time, since the chance of contact between the outer periphery of the blade contact adjusting sheet 1 and the inner wall of the holding portion 150 is small, the blade contact adjusting sheet 1 is inserted into the holding portion 150 with almost no resistance. Subsequently, as shown in FIG. 6B, when the restraint of the blade contact adjustment sheet 1 is completely released, the blade contact adjustment sheet 1 expands to the winding diameter D ₂ in an attempt to restore the original shape, and the blade contact The outer periphery of the adjustment sheet 1 is in contact with the inner wall of the holding portion 150. As a result, the blade contact adjustment sheet 1 is held by the holder 150.

By the way, if the blade contact adjustment sheet 1 in the wound state is inserted into the holding portion 150 from either the left side opening portion 156 as in the conventional case and is held, the blade contact adjustment sheet 1 is inserted into the holding portion 150. The moment the operator releases the hand, the restraint by the operator's hand is released. Then, the blade contact adjustment sheet 1 in the rolled state tries to restore to the original shape, the blade contact adjustment sheet 1 is expanded from the winding diameter D ₁ to the winding diameter D _2, and the outer periphery of the expanded blade contact adjustment sheet 1 is obtained. Contacts the inner wall of the holding part 150. As a result, the resistance against the operation of inserting the blade contact adjustment sheet 1 into the holding unit 150 increases. Further, in order to insert and hold the rolled blade contact adjustment sheet 1 into the holding portion 150 from either the left or right side opening portion 156, insert the wound blade contact adjustment sheet 1 in the longitudinal direction. Therefore, a strong resistance is always applied during the insertion operation of the blade contact adjustment sheet 1, which is troublesome.

When taking out the blade contact adjustment sheet 1 from the holding portion 150, it can be easily taken out by pulling it out from the side opening portion 156 as in the conventional case. Alternatively, if the blade-contact adjusting sheet 1 in the rolled state has a certain degree of rigidity, the edge of the blade-contact adjusting sheet 1 protruding from the side opening 156 is pushed in the vertical direction to flatten the edge. Then, the central portion of the blade contact adjustment sheet 1 also flattens following the shape of the end portion, so that it can be taken out from the open portion 155.

The dimensions of the holding portion 150 (holding portion back portion 150a, holding portion upper portion 150b, and holding portion lower portion 150c) can be set in consideration of the sizes of the die substrate 11 and the blade contact adjustment sheet 1, but the punching die 10 It is preferable to set in consideration of the blade 12 and/or the pressing member 13. As shown in FIG. 6, a pressing member 13 for pressing the material sheet of the packaging box is arranged on the upper plate surface of the mold substrate 11 along both sides of the blade 12 planted in the mold substrate 11. Has been done. Generally, the pressing member 13 is mainly made of a sponge material and is arranged on the plate surface of the mold substrate 11 so as to be higher than the cutting edge of the blade 12 by 2 to 3 mm. The height H of the holding unit 150 from the plate surface on the upper side of the mold substrate 11 is set so that the blade 12 and/or the pressing member 13 is above the mold substrate 11 when the blade contact adjustment sheet holder 100 is mounted on the mold substrate 11. It is preferable that the height is substantially the same as or slightly lower than the height from the plate surface. Accordingly, even when the blade contact adjustment sheet holder 100 is mounted on the die substrate 11, the holding section 150 does not come into contact with the material sheet during the punching operation, which does not hinder the punching operation. Further, it is preferable that the length of the holding portion 150 in the left-right direction is substantially the same as or slightly shorter than the length of one side (long side or short side) of the mold substrate 11 on which the blade contact adjustment sheet holder 100 is mounted.

It is preferable that the blade contact adjustment sheet holder 100 has a detachment prevention unit 157 for preventing the blade contact adjustment sheet 1 from detaching. By including the drop-out prevention means 157, it is possible to reduce the risk that the blade contact adjustment sheet 1 will accidentally drop off from the opening 155 during storage.

As shown in FIGS. 2 and 4(a), the fall-off prevention means 157 includes a front end edge portion of the opening portion 155 (that is, a front end edge portion of the holding portion upper portion 150b and/or the holding portion lower portion 150c). ) Is preferably a bent piece. Such a bent piece can provide the fall-off preventing means 157 having a high fall-off preventing property even though it has a simple structure.

The right half may be configured by the back portion a of the holding portion and the lower portion 150c of the holding portion. Alternatively, the holding part 150 is composed of a holding part back part 150a and a holding part lower part 150c, and after placing the blade contact adjustment sheet 1 in a state of being wound from the outside of the mold substrate 11 on the holding part lower part 150c, a string or a cover or the like. The blade-contact adjusting sheet 1 may be locked by the fall prevention means 157 and held by the holding portion 150.

[Blade contact adjustment sheet holding method]
The blade contact adjustment sheet holding method of the present invention can be carried out by using the blade contact adjustment sheet holder 100 of the present invention, and the holder 150 of the blade contact adjustment sheet holder 100 is mounted on the die substrate 11. It includes a mounting step and a holding step of holding the blade contact adjustment sheet 1 in the holding section 150 from an opening section 155 formed facing the outside of the mold substrate 11. Hereinafter, each step will be described.

<Installation process>
In the mounting step, one or more blade contact adjustment sheet holders 100 are mounted on one side (long side or short side) of the die substrate 11 of the punching die 10 via the mounting portion 110. At this time, it is preferable that the blade contact adjustment sheet holder 100 does not protrude from one side of the die substrate 11 to be mounted. By doing so, it can be compactly stored on a storage shelf or the like.

In the mounting step, it is preferable that at least a part of the holder back 150a is in contact with the side surface of the mold substrate 11. This enables stable attachment of the blade contact adjustment sheet holder 100.

After the mounting step, if necessary, a locking hole that penetrates the mounting portion 110 and reaches the die substrate 11 is drilled by an electric drill or the like, and a screw is screwed into the locking hole to mount the mounting portion. A screwing step of fixing 110 to the mold substrate 11 may be performed. Thereby, it is possible to reliably prevent the blade contact adjustment sheet holder 100 from coming off the mold substrate 11.

<Holding process>
In the holding step, the blade contact is performed from the open portion 155 formed facing the outside of the mold substrate 11 (the side opposite to the mounting portion 110 and distal from the end of the mold substrate 11) to the holding portion 150. The adjustment sheet 1 is held in a rolled state. That is, as shown by an arrow A in FIG. 6A, the blade-contact adjusting sheet 1 is slid to the holder 150 from a direction approaching one side of the mold substrate 11 on which the blade-contact adjusting sheet holder 100 is mounted from the outside. .. By doing so, the blade contact adjustment sheet 1 can be moved to the inside of the holding portion 150 before the diameter is increased from the winding diameter D ₁ to the winding diameter D ₂ , and the blade contact adjustment sheet 1 and the inner wall of the holding portion 150 are Since there is little chance of contact, the blade contact adjustment sheet 1 can be held (inserted) in the holder 150 with almost no resistance. At this time, if the blade-contact adjusting sheet 1 is wound so that the winding diameter is as small as possible, the chance of contact between the blade-contact adjusting sheet 1 and the inner wall of the holding portion 150 is reduced, and as a result, the blade contact is adjusted. It is possible to reduce the resistance when the adjustment sheet 1 is held by the holding portion 150. Subsequently, as shown in FIG. 6B, when the restraint of the blade contact adjustment sheet 1 is completely released, the blade contact adjustment sheet 1 expands to the winding diameter D ₂ in an attempt to restore the original shape, and the blade contact The adjustment sheet 1 is in contact with the inner wall of the holding unit 150. As a result, the holding unit 150 holds the blade contact adjustment sheet 1.

As shown in FIG. 1, when a plurality of blade contact adjustment sheet holders 100 are mounted on the mold substrate 11, the blade contact adjustment sheets 1 are sequentially held by the holders 150 of all the blade contact adjustment sheet holders 100 mounted. Let In addition, when a plurality of blade contact adjustment sheet holders 100 are mounted on the mold substrate 11, the blade contact adjustment sheet holders 100 hold the blade contact adjustment sheet 1 near both ends in the lengthwise direction of the wound blade contact adjustment sheet 1. Preferably. As a result, it is possible to prevent both ends of the blade contact adjustment sheet 1 from hanging and deforming due to gravity during storage.

The blade contact adjusting sheet holder and the blade contact adjusting sheet holding method of the present invention are used for the purpose of storing both a punching die used at the time of manufacturing a packaging box and a blade contacting adjustment sheet corresponding to the punching die. Is possible.
