Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cylindrical support plate, for example, when a cylindrical body in which a spun yarn is wound around a cylindrical core tube is packed in a box, the cylindrical body is moved by laying in the box. The present invention relates to a cylindrical support plate to be regulated.
[0002]
[Prior art]
Conventionally, as this type of support plate, as shown in FIG. 7A, one formed by two corrugated paperboards 30 and 31 that are superposed vertically is known. The lower corrugated paperboard 31 is provided with a first standing piece 32 that stands up separately from the paperboard 31. The upper corrugated paperboard 30 includes a pair of second upright pieces 33 that are separated from the paperboard 30 and stand up crossing the upright direction of the first upright pieces 32. Then, by superposing the two corrugated paperboards 30 and 31 up and down to raise the first upright piece 32, the pair of second upright pieces 33 are pushed open from below, as shown in FIG. 7 (b). Further, the locking claw 34 formed at the tip of the first upright piece 31 engages with the concave portion 35 formed at the upper edge of the second upright piece 33 to restrict the movement of the cylindrical body W. 36 is formed. And the support plate 37 which supported the cylindrical body W is accommodated in the packaging box which is not shown in figure. The cylindrical body W is, for example, a product in which a spun yarn or the like is wound around a cylindrical core tube, and the cylindrical body W is supported by a support plate 37 and stored in a packaging box. Contact and damage between the cylindrical bodies W during transportation or the like can be prevented. However, since the support plate 37 must be composed of two corrugated paperboards 30 and 31 as shown in FIG. 7A, there is a disadvantage that the cost is high.
[0003]
Therefore, as shown in FIG. 8 (a), the cardboard paperboard 38 is provided with a first standing piece 39 that stands up and separates from the paperboard 38, and is further released from both sides of the first standing piece 39 of the paperboard 38. It is conceivable to provide a pair of second upright pieces 40 that stand in a direction opposite to the first upright pieces 39. Then, as shown in FIG. 8 (b), the concave portions 41 on both sides of the upper end portion of the first standing piece 39 standing up are engaged with the concave portions 42 on the inner side of the upper end portions of the two second standing pieces 40 standing up. A support portion 43 that restricts the movement of the body W is formed. As a result, the support plate 44 made of a single cardboard paperboard 38 can be formed, and the cost can be reduced as compared with the support plate 37 formed by two cardboard paperboards 30 and 31.
[0004]
By the way, this type of support plate 1 is formed with a plurality of support portions 43 formed in advance in order to efficiently perform the operation of storing the cylindrical body W in a packaging box. The support plates 44 are stacked one above the other. Then, the uppermost one of the plurality of stacked support plates 44 is taken out, and the cylindrical body W is placed on the support plate 44.
[0005]
However, as shown in FIG. 8B, when the support portion 43 is formed by a single piece of corrugated paperboard 38, the corrugated paperboard 38 when the first upright piece 39 and the second upright piece 40 are released. Since the shape of the hole 45 formed in the upper portion corresponds to the protruding shape of the support portion 43, the support portion 43 of the lower support plate 44 is supported by the upper support plate 44 in the stacked upper and lower adjacent support plates 44. There is a problem that the workability at the time of mounting the cylindrical body W on the support plate 44 is lowered due to being difficult to be fitted and removed from the hole 45 of the support portion 43 of the plate 44.
[0006]
[Problems to be solved by the invention]
Solving such inconvenience, the present invention can be formed in a single-piece configuration to reduce the material cost, and can be prevented from being fitted to each other during stacking, and workability can be improved. It aims at providing the support plate of a cylindrical body.
[0007]
[Means for Solving the Problems]
In order to achieve this object, the present invention provides a cylindrical body support plate that regulates and supports the movement of a cylindrical body, and includes a flat substrate and a plurality of free pieces provided on the substrate. Bending along the crease line is formed so as to rise on the substrate, and is inserted into the inside of the cylindrical body to support the cylindrical body, and corresponds to the free piece by releasing the free piece. A hole formed through the substrate in the shape, and the support portion formed by the free piece is in a standing direction through a first fold line along the connecting portion between the free piece and the substrate. A front inclined portion that is bent and inclined, and a rear inclined portion that is bent and inclined toward the substrate through a second fold line along the top portion with the upper edge of the front inclined portion as a top portion, Folded horizontally through a third fold line along the lower edge of the rear slope, A rear horizontal portion that is positioned on the same plane as the substrate in the hole portion, and the hole portion has a pair of cutouts formed on the left and right end portions of the free piece to form the support portion. A protrusion that protrudes in the horizontal direction and remains in the hole corresponding to both notches, and a position where the rear horizontal portion is displaced forward when the free piece is bent and raised to form the support portion. And an engaging portion that engages with the rear horizontal portion and maintains the raised state of the support portion.
[0008]
According to the present invention, the support piece that rises on the substrate is formed by bending the free piece provided on the substrate along the first to third fold lines. That is, when the support portion is formed, the second fold line is folded in the mountain fold direction, and the first and third fold lines are folded in the valley fold direction. Thereby, the said front side inclination part and the said back side inclination part are formed, and the said free piece protrudes. The rear horizontal portion located at the rear end portion of the free piece moves to the front end side when the front inclined portion and the rear inclined portion are formed. At this position, a rear horizontal portion is engaged with the engaging portion, and a support portion is formed in which the raised state of the front inclined portion and the rear inclined portion is maintained. Thus, the support plate of this invention can form a support part from one flat plate, and can reduce cost.
[0009]
On the other hand, the hole is formed in the substrate as the loose piece is bent and raised. In the hole portion, protrusions formed corresponding to the pair of notches of the free piece protrude inward of the hole portion and remain. As described above, the front inclined portion and the rear inclined portion are raised in the standing direction, so that the pair of notches of the free piece are displaced in the front direction with respect to the position directly above the protrusion. As described above, the support part and the hole part are formed so as to be displaced, so that the planar view shape of the support part and the planar view shape of the hole part are not compatible.
[0010]
Thus, when a plurality of support plates are stacked vertically in a horizontal posture, even if the support portion of the lower support plate attempts to fit into the hole portion of the upper support plate, the protrusion that protrudes inward of the hole portion Therefore, the support portion of the lower support plate can be reliably prevented from fitting into the hole portion of the upper support plate. Therefore, it is possible to easily take out the plurality of stacked support plates from above, and it is possible to improve workability when packaging the cylindrical body.
[0011]
In the present invention, the rear horizontal portion is formed in a shape that gradually widens toward the rear edge, and the engaging portion is formed in a shape corresponding to the rear horizontal portion in a part of the hole. When the free piece is bent and raised to form the support part, the rear horizontal part maintains a position on the same plane as the substrate and is displaced forward from the rear edge of the hole part. Thus, the raised state of the support portion is maintained by press-contacting with both sides of the rear horizontal portion that gradually widens toward the rear end edge.
[0012]
When the free piece is raised to form the front inclined portion and the rear inclined portion, the rear horizontal portion is moved horizontally toward the front end side of the free piece. Since the rear horizontal portion is formed in a shape that gradually widens toward the rear end edge, as the rear horizontal portion moves forward, the pressure contact force of the engaging portion to both end edges of the rear horizontal portion is increased. To increase. Then, the movement of the rear horizontal portion is restricted, and the rear horizontal portion is pressed and engaged with the engagement portion. Thereby, the raised state of the front side inclined part and the rear side inclined part can be easily maintained only by moving the rear side inclined part horizontally.
[0013]
Further, in the present invention, the substrate includes a locking portion formed to extend above the top of the support portion by raising another free piece formed in a part thereof, and the locking portion. And a locking hole formed by releasing another free piece when forming, and in a state where a plurality of the support plates are stacked in the vertical direction, the base plate formed on the lower support plate adjacent to each other. It is preferable that the locking portion is inserted into a locking hole formed in the substrate of the other support plate above.
[0014]
In the support plate of the present invention, when the plurality of support plates are stacked in the vertical direction in a horizontal posture, the support portion and the hole portion are not fitted. However, while it is easy to cancel the stacking, if the upper and lower support plates are misaligned, the stacked support plates may collapse. Therefore, the other release piece is provided and released from the substrate to form the engagement portion and the engagement hole, and the engagement portion formed on the lower support plate is formed on the upper support plate. It is inserted into the locking hole. Accordingly, it is possible to prevent the positional deviation between the upper and lower support plates without hindering the easy release of the stack, and it is possible to reliably prevent the stacked support plates from collapsing.

[0016]
As shown in part in FIG. 1, the support plate 1 of the present embodiment supports a cylindrical body W in which spun yarn or the like is wound around a paper tube, and is laid on a packaging box (not shown). The movement and contact of the plurality of cylindrical bodies W are prevented. The support plate 1 includes a flat substrate 2 formed of corrugated paperboard and a plurality of support portions 3 formed integrally with the substrate 2, and the support portion 3 is inserted into the cylindrical body W. Thus, the movement of the cylindrical body W is restricted.
[0017]
As shown in FIG. 2, the first free piece 4 is formed on the substrate 2 so as to be freely separated by a score line. In FIG. 2, for convenience of explanation, the lower side in the figure is described as the front side. The first free piece 4 is formed such that a front end edge thereof is connected to the substrate 2 via a first fold line a. The first free piece 4 is formed with a second fold line b and a third fold line c that are parallel to each other with a space from the first fold line a. On the left and right sides along the second fold line b, a part of the cut line is bent in a substantially V shape, and further, on the rear side of the third fold line c of the first free piece 4 The cut line is formed so as to gradually widen toward the rear end edge of the first free piece 4. As will be described later, the support portion 3 shown in FIG. 1 is formed by the first free piece 4.
[0018]
Further, as shown in FIG. 2, a plurality of second free pieces 5 are formed on the substrate 2 so as to be freely separated by a substantially U-shaped cut line. The second free piece 5 is formed such that one side edge thereof is connected to the substrate 2 via a fourth fold line d. Further, the second free piece 5 is formed in such a length that its upper end portion is positioned higher than the support portion 3 shown in FIG. 1 when it is erected via the fourth fold line d as will be described later. Yes.
[0019]
The support portion 3 is formed by bending the first free piece 4 through the first to third fold lines a, b, and c so as to protrude from the substrate 2 as shown in FIG. That is, if FIG. 1 and FIG. 2 are compared and demonstrated, between FIG. 1 and the 1st crease line a of the 1st free piece 4 and the 2nd crease line b will be made into the front side inclination part 6 in FIG. The Further, in FIG. 2, a portion between the second fold line b and the third fold line c of the first free piece 4 is a rear inclined portion 7 in FIG. 1. Further, in FIG. 2, the portion from the third fold line c of the first free piece 4 to the rear end edge is the rear horizontal portion 8 in FIG. A part of the substantially V-shaped cut line on the left and right sides along the second fold line b in FIG. 2 is a notch 9 in FIG. 1 and is formed on the substrate 2 by forming the support portion 3. The projection 11 of the hole 10 is made.
[0020]
When forming the support part 3 from the 1st free piece 4, as shown in FIG. 3, the said back side horizontal part 8 is moved toward the front side horizontally. At this time, as shown in FIG. 1, the second fold line b is folded in the mountain fold direction, and the first fold line a and the third fold line c are folded in the valley fold (opposite side to the second fold line b). . Thereby, first, a pair of notches 9 are formed on the left and right sides of the second fold line b, and at the same time, a pair of protrusions 11 are formed in the hole 10. When the fold lines a, b, and c are further bent, the position of the second fold line b (top e) is displaced forward as shown in FIG. As a result, the positions of the notch 9 and the protrusion 11 are shifted as is apparent in plan view. Further, as shown in FIG. 3, when the rear end edge of the rear horizontal portion 8 is moved away from the inner edge of the hole 10 and moved forward, the rear horizontal portion 8 faces the rear end edge. Due to the gradually widening shape, a part of the hole 10 having a shape corresponding to the rear horizontal portion 8 is brought into pressure contact with both sides of the rear horizontal portion 8 to form the engaging portion 12. Thus, the rear horizontal portion 8 is held without retreating, and the support portion 3 is maintained in a raised state on the substrate 2. Thus, since the support plate 1 of this embodiment can be formed by one sheet of corrugated paperboard, it can be manufactured at a lower cost than that formed by two conventional corrugated paperboards.
[0021]
As shown in FIG. 1, the support plate 1 supports the cylindrical body W by inserting a support portion 3 into the inner periphery of the cylindrical body W, and is then stored in a packaging box (not shown). For the support plate 1 that does not support the W-shaped body W, a plurality of support plates 1 on which the support portions 3 are formed in advance are stored in a vertically stacked state. At this time, first, as shown in FIG. 4, the second release piece 5 is released from the substrate 2 and is raised along the fourth fold line d to form the locking portion 13. At this time, a locking hole 14 is formed in the substrate 2 by releasing the second free piece 5. The locking portion 13 has a pair of recesses 15 formed on both sides thereof, and the width of the upper portion 16 is slightly smaller than the lower portion 17 via the recess 15. The locking hole 14 is formed with a pair of convex portions 18 corresponding to the concave portions 15 of the locking portion 13, and the width dimension on the locking portion 19 side is made larger than the other 20 via the convex portions 18.
[0022]
The plurality of support plates 1 in which the locking portions 13 and the locking holes 14 are thus formed are stacked as shown in a partial cross-sectional view in FIG. Each support plate 1 has a protrusion 11 formed in a hole 10, and a notch 9 separated from the protrusion 11 is positioned forward of a position directly above the protrusion 11 due to displacement when the support 3 is formed. As a result, the protrusion 11 abuts against a portion other than the notch 9 to prevent the support portion 3 from being inserted into the hole 10, and the support portion 3 is prevented from fitting into the hole 10. Furthermore, when stacking the support plates 1, the locking portions 13 of the lower support plate 1 are inserted into the locking holes 14 of the upper support plate 1. At this time, referring to FIG. 4, the locking part 13 has the narrow upper part 16 inserted into the wide part 19 on the locking part 13 side of the locking hole 14, and further the convex part of the locking hole 14. 18 prevents the locking portion 13 from tilting and entering the narrow portion 20 of the locking hole 14. As a result, it is possible to easily remove the locking portion 13 from the locking hole 14, and the upper and lower support plates 1 are prevented from being displaced in the horizontal direction and broken, and the stacked state of the support plates 1 is maintained. can do.
[0023]
And since each support plate 1 is piled up without fitting the support part 3 and the hole part 10, when making the support plate 1 support the cylindrical body W, the piled-up support plate 1 is made into the uppermost part. It is possible to smoothly carry out the removal from the object.
[0024]
In the present embodiment, the rear horizontal portion 8 is gradually widened toward the rear edge, and a part of the hole 10 having a shape corresponding to the rear horizontal portion 8 is the rear horizontal portion 8. Although the engagement part 12 is shown in pressure contact with both sides, the engagement part in the present invention is not limited thereto. For example, as shown in FIG. 6, convex portions 21 may be provided on both sides of the rear horizontal portion 8, and concave portions 22 corresponding to the convex portions 21 may be provided on the substrate 2 to serve as engaging portions. Then, after the rear horizontal portion 8 is once separated from the substrate 2, the raised portions of the support portion 3 can be maintained by engaging the convex portions 21 and the concave portions 22 on the same plane as the substrate 2 again. .
