Description

The present invention relates to a gap packing material for a thread path gap of a sewing machine .

Conventionally, there has been known a packaging material that prevents the dewatering tank in the washing machine from shaking when transporting and transporting the washing machine, and prevents the dewatering tank from colliding with the surroundings and causing dents to be made. (For example, refer to Patent Document 1).
The packing material of the washing machine is sandwiched between the lid of the washing machine and the dehydration tank, thereby maintaining the dehydration tank in a predetermined arrangement and restricting the movement of the dehydration tank to be shaken. .

Further, when the sewing machine 1 as shown in FIG. 9 (a) is transported and transported, the sewing machine frame (machine frame) 2 is deformed in the sewing machine 1 that has been subjected to a strong impact due to dropping, etc. A gap packing material 50 as shown in FIG. 9 (b) is known, which is inserted into the yarn path gap 3 so that 3 is not blocked.
The gap packing material 50 has a folded thickness approximately the same as the width of the yarn path gap 3, and the insertion portion 50 a of the gap packing material 50 is inserted in the yarn path gap 3 in advance. Even when a strong impact that causes the sewing machine frame 2 to deform is applied to the sewing machine 1, the yarn path gap 3 can be secured.
JP 2004-49402 A

However, in the case of the above-described conventional packing material for gaps in the sewing machine, the gap packing material 50 is removed from the sewing machine frame 2 with a tape T or the like so that the gap packing material 50 does not fall out of the yarn path gap 3. For example, when performing demonstration sale of the sewing machine 1 at a plurality of places, the unpacking and packing of the sewing machine 1 at each place is repeated. At this time, by repeatedly removing and attaching the gap packing material 50, the adhesive force of the tape T is reduced, and it may be difficult to suitably arrange the gap packing material 50 in the yarn path gap 3. It was.
Further, when the gap packing material 50 is removed from the yarn path gap 3, the tape T may be peeled off from the gap packing material 50 so as to peel the surface of the gap packing material 50. Even in such a case, the adhesive strength of the tape T is reduced, and it may be difficult to reuse the gap packing material 50 whose surface has been peeled or torn.
Thus, when the gap packing material 50 is disposed in the yarn path gap 3 using the tape T, there is a problem that it may be difficult to repeatedly attach and detach the gap packing material 50 to the yarn path gap 3. It was.

An object of the present invention, it is possible to ensure the yarn path gap in the sewing machine, it is to provide clearance for the packing material of the yarn path clearance repeated available sewing machines.

In order to solve the above problems, the invention according to claim 1 is a gap packing material for a yarn path gap of a sewing machine, the gap packing material comprising a sheet-like member having a plurality of folds, and the sheet. The sheet-like member is inserted into the yarn path gap provided in the sewing machine frame, and the sheet-like member is bent at least at two locations on the inner side of the sewing machine frame from the yarn path gap to thereby remove the thread-like gap from the yarn path gap. A wide wide portion is formed, and the folded sheet member is stacked in the yarn path gap, and the sheet member is folded so as to separate the end portions on both sides of the sheet member. A narrow portion having substantially the same thickness as the width of the yarn path gap is formed .

According to claim 1 the invention described, gap between packing materials, as the sheet-like member is bent at a plurality of folds, so that a constricted portion wide portion is formed. In particular, the sheet-like member is inserted into the yarn path gap, and at least two portions of the sheet-like member are bent on the inner side of the sewing machine frame from the yarn path gap to form a wide portion and a constricted portion. A material is disposed in the thread path gap of the sewing machine .
The clearance packing material, by being KyoIri the yarn path clearance of the sewing machine, so that substantially have the same thickness as the width of the yarn channel gap, constricted portion of the sheet member are laminated in the yarn path gap, It gets caught in the thread path gap. And even if a strong load that closes the yarn path gap may act on the device, the constricted portion of the gap packing material is inserted in the yarn path gap Therefore, the yarn path gap is not blocked, and the constricted portion ensures the width and interval of the yarn path gap.
Further, the gap for packaging, the wide portion having a width greater than the width of the yarn channel gap, the sheet-like member in the inner side of the machine frame than the yarn path gap is arranged to be formed by being bent at least two positions so have become so that, the wide portion is less likely to come out of the yarn path gap, the gap for the packing material is less likely to fall off from the yarn path gap.
Further, by pulling one end portion of the gap packing material inserted into the yarn path gap, the fold line in which the sheet member is bent is restored to the flat state before being bent, so that the wide portion disappears. It is like that. Since the formed wide portion is eliminated, the gap packing material can come out of the yarn path gap, so that the gap packing material can be removed from the yarn path gap and removed.

According to the first aspect of the present invention, the gap packing material is formed so that the wide portion and the constricted portion are formed such that the sheet-like member is bent at a plurality of folds. In particular, the sheet-like member is inserted into the yarn path gap, and at least two portions of the sheet-like member are bent on the inner side of the sewing machine frame from the yarn path gap to form a wide portion and a constricted portion. A material is disposed in the thread path gap of the sewing machine .
The clearance packing material, by being KyoIri the yarn path clearance of the sewing machine, so that substantially have the same thickness as the width of the yarn channel gap, constricted portion of the sheet member are laminated in the yarn path gap, It gets caught in the thread path gap. And even if a strong load that would block the yarn path gap may act on the sewing machine , the constricted portion of the gap packing material is inserted in the yarn path gap. The yarn path gap is not blocked, and the constricted portion ensures the width and interval of the yarn path gap.
Further, the gap for packaging, the wide portion having a width greater than the width of the yarn channel gap, the sheet-like member in the inner side of the machine frame than the yarn path gap is arranged to be formed by being bent at least two positions so have become so that, the wide portion is less likely to come out of the yarn path gap, the gap for the packing material is less likely to fall off from the yarn path gap.
Further, by pulling one end portion of the gap packing material inserted into the yarn path gap, the fold line in which the sheet member is bent is restored to the flat state before being bent, so that the wide portion disappears. It is like that. Since the formed wide portion is eliminated, the gap packing material can come out of the yarn path gap, so that the gap packing material can be removed from the yarn path gap and removed.

Thus, the gap packing material that secures the thread path gap of the sewing machine can be easily attached to and detached from the thread path gap.
In particular, the gap packing material has a shape in which the sheet-like member is folded at a plurality of creases, unlike the conventional gap packing material, which uses an adhesive tape to attach and detach the gap packing material to the sewing machine. Accordingly, the gap packing material is disposed in or removed from the yarn path gap, so that it cannot be used due to a decrease in the adhesive strength of the tape. That is, the gap packing material can be easily attached to and detached from the yarn path gap and can be used repeatedly.
Therefore, it can be said that the gap packing material is a gap packing material that can secure a thread path gap of the sewing machine and can be used repeatedly.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment 1)
FIG. 1A is a perspective view showing a state in which the gap packing material 10 according to the present invention is disposed on the sewing machine 1, and FIG. 1B shows the gap packing material 10 according to the present invention. It is a perspective view shown.

As shown in FIG. 1A, a sewing machine 1 that is a predetermined device includes a sewing machine frame 2 that covers a driving mechanism unit (not shown) of the sewing machine 1, and the sewing machine frame 2 has a yarn path that is a predetermined gap. A gap 3 is provided.
The yarn path gap 3 is a gap that functions as a sewing thread path from a sewing thread supply source (not shown) to a sewing needle (not shown), and the width of the yarn path gap 3 is, for example, about 0.8 to 1.2 mm. is there.

As shown in FIGS. 1B and 2, the gap packing material 10 is made of, for example, a sheet-like member such as thick paper or a resinous sheet having bendability, for example, 0.8 to 1.2 mm. When using the yarn path gap 3 having a width of 5 mm, the thickness of the gap packing material 10 is preferably about 0.4 to 0.6 mm. That is, it is preferable that the thickness when the gap packing material 10 is folded in two and stacked is substantially the same as the width of the yarn path gap 3.
Further, the gap packing material 10 has a plurality of folds (in the first embodiment, four folds 11a, 11b, 11c, and 11d from the left side in FIG. 2). The length of the gap packing material 10 in the crease direction is preferably substantially equal to the length of the yarn path gap 3 in the longitudinal direction (direction perpendicular to the width direction).

Next, a procedure for attaching / detaching the gap packing material 10 to / from the yarn path gap 3 of the sewing machine 1 will be described.
First, as shown in FIG. 3, the gap packing material 10 is folded at a fold (for example, a fold 11 c), and the folded portion is inserted into the yarn path gap 3.

Next, as shown in FIG. 4, the two folds 11 b and 11 c of the gap packing material 10 are bent so as to protrude toward the inner side of the sewing machine frame 2.
As described above, the two folds 11b and 11c at the two locations of the gap packing material 10 are bent inside the yarn path gap 3 and inside the sewing machine 1 (sewing frame 2), whereby the wide portion 12 is formed. It is formed.

Furthermore, as shown in FIG. 4, at the yarn path gap 3 portion (specifically, the portion where the end of the sewing machine frame 2 faces the yarn path gap 3), the fold line 11a and the fold line 11d of the gap packing material 10 are provided. The two folds 11a and 11d of the gap packing material 10 are folded back in the direction opposite to the folds 11b and 11c so that the end portions 10a on both sides of the gap packing material 10 are separated from each other. Bend it.
In this way, the constricted portion 13 is formed when the convex portions of the two folds 11 a and 11 d of the gap packing material 10 come close to each other in the yarn path gap 3.

The gap packing material 10 is disposed in the sewing machine 1 (yarn path gap 3) so that the end portion 10a of the gap packing material 10 contacts the surface of the sewing machine frame 2.
In addition, as shown in FIG.1 (b), since the constriction part 13 formed in the packing material 10 for gaps has the thickness which the packing material 10 for gaps was folded in two and overlapped, The thickness 13 a in the width direction of the yarn path gap 3 has substantially the same width as the width of the yarn path gap 3. The width 12 a of the wide portion 12 is wider than the thickness 13 a of the constricted portion 13.
That is, on the inner side of the yarn path gap 3 (sewing machine frame 2), the gap packing material 10 has a plurality of folds folded so as to have a substantially triangular shape in cross section. Since the wide portion 12 having a width 12 a wider than the width of the yarn path gap 3 is formed, the wide portion 12 does not come out of the yarn path gap 3 due to vibration or inclination acting on the sewing machine 1. The gap packing material 10 is less likely to fall out of the yarn path gap 3.

  Further, as shown in FIG. 5, when the flange surface 10b on the one end 10a side of the gap packing material 10 is picked and pulled so as to be pulled up from the sewing machine frame 2, the gap packing material 10 has a substantially triangular shape in sectional view. Each of the folds (11a, 11b, 11c, 11d) that has been folded so as to be restored to the planar shape before being folded, so that the wide portion 12 disappears. By eliminating the formed wide portion 12, the gap packing material 10 can come out of the yarn path gap 3, and the gap packing material 10 can be extracted from the yarn path gap 3 and removed.

  Thus, the gap packing material 10 in which the wide portion 12 and the constricted portion 13 are formed so that the sheet-like member is bent at a plurality of folds is inserted into the yarn path gap 3 of the sewing machine 1. Then, the constricted portion 13 is clamped in the yarn path gap 3. Even if the sewing machine frame 2 is deformed due to a strong load applied to the sewing machine 1, the constricted portion 13 of the gap packing material 10 is sandwiched in the yarn path gap 3. The constricted portion 13 can secure the width and interval of the yarn path gap 3, and the yarn path gap 3 is not blocked.

Moreover, since the wide packing portion 12 wider than the width of the yarn path clearance 3 is formed in the gap packing material 10, even if vibration or inclination acts on the sewing machine 1 during transportation, conveyance, etc., the wide portion 12 is difficult to come out of the yarn path gap 3 so that the gap packing material 10 does not fall out of the yarn path gap 3.
Further, the gap packing material 10 can be easily detached from the yarn path gap 3 by pulling the flange surface 10 b of the gap packing material 10 inserted into the yarn path gap 3.

Thus, the gap packing material 10 that secures the yarn path gap 3 of the sewing machine 1 can be easily attached to and detached from the yarn path gap 3.
In particular, the gap packaging material 10 is different from the conventional packaging material for gaps (for example, the gap packaging material 50) in that the gap packaging material is attached to and detached from the sewing machine using an adhesive tape T. Since the gap packing material 10 is arranged in or removed from the yarn path gap 3 in accordance with the shape obtained by bending the shape member with a plurality of creases, the adhesive strength of the tape T is reduced, etc. It will not be impossible to use. That is, the gap packing material 10 can be easily attached to and detached from the yarn path gap 3 and can be used repeatedly.
Therefore, it can be said that the gap packing material 10 is a gap packing material that can secure the yarn path gap 3 in the sewing machine 1 and can be used repeatedly.

(Embodiment 2)
Next, Embodiment 2 of the gap packing material according to the present invention will be described. In addition, the same code | symbol is attached | subjected to the same part as Embodiment 1, and only a different part is demonstrated.

  As shown in FIGS. 6A and 6B, the gap packing material 20 is bent at four folds so as to have a substantially triangular shape in cross section, and is wider than the width of the yarn path gap 3. And a constricted portion 23 having a thickness substantially the same as the width of the yarn path gap 3 is formed.

  Further, the flange surface 20b on the one end portion 20a side of the gap packing material 20 is formed wider and larger than the surface on the other end portion 20a side. An arrow-shaped punching hole 20c is formed on the flange surface 20b of the gap packing material 20 and extends toward the end 20a of the flange surface 20b.

  Thus, by enlarging the flange surface 20b of the gap packing material 20, the flange surface 20b can be easily picked and the direction in which the flange surface 20b is pulled according to the arrow-shaped punch hole 20c can be easily understood. It becomes possible to remove the packing material 20 from the yarn path gap 3 more easily.

In particular, the process of manufacturing the gap packing material 20 can be simplified by forming an arrow indicating the direction of pulling the collar surface 20b as a punch hole 20c instead of attaching it by a process such as printing.
In other words, when printing the arrow attached to the flange surface 20b by printing, for example, two steps are required, that is, a die cutting step for cutting out a paper piece that becomes the gap packing material 20 and making a crease and a printing step for printing the arrow. However, when the arrow attached to the flange surface 20b is formed as the punching hole 20c, for example, one step of a die cutting process of cutting out a piece of paper to be the gap packing material 20 and removing the punching hole 20c to make a crease. Thus, the gap packing material 20 can be manufactured.
Thus, the manufacturing cost of the gap packing material 20 can be reduced by omitting the printing process and manufacturing the gap packing material 20 in one step of die cutting.

(Embodiment 3)
Next, Embodiment 3 of the gap packing material according to the present invention will be described. In addition, the same code | symbol is attached | subjected to the same part as Embodiment 1, and only a different part is demonstrated.

As shown in FIG. 7, the sewing machine frame 2a of the sewing machine 1a can be detached so as to be divided at the sewing machine surface portion. In addition, illustration of the sewing machine drive mechanism etc. in the sewing machine frame 2a is omitted.
When a part of the sewing machine frame 2a is removed, one end 3a of the yarn path gap 3 provided in the sewing machine frame 2a appears on the end surface of the sewing machine frame 2a.

  As shown in FIG. 8, the gap packing material 30 has a wide portion 32 having a width wider than the width of the yarn path gap 3 and substantially the width of the yarn path gap 3 so as to exhibit a substantially letter shape in cross section. A constricted portion 33 having the same thickness is formed. The gap packing material 30 is formed of, for example, an elastic member made of a flexible and elastically deformable resin material.

When the gap packing material 30 is disposed in the yarn path gap 3 of the sewing machine 1a, the wide portion 32 of the gap packing material 30 is inserted into the sewing machine 1a (sewing frame) from the yarn path gap 3, as shown in FIG. 2a), and the constricted portion 33 is in a direction intersecting with the width direction of the yarn path gap 3 (for example, a direction orthogonal thereto) and along the longitudinal direction of the yarn path gap 3. The gap packing material 30 is inserted into the yarn path gap 3 so as to be inserted.
Further, when the gap packing material 30 is removed from the yarn path gap 3 of the sewing machine 1a, the constricted portion 33 of the gap packing material 30 is removed so as to be pulled out along the longitudinal direction of the yarn path gap 3. That's fine.

Even such a gap packing material 30 can be easily attached to and detached from the yarn path gap 3 of the sewing machine 1a, and the yarn path gap 3 can be suitably secured.
The gap packing material 10 and the gap packing material 20 may be inserted into or removed from the sewing machine 1a along the longitudinal direction of the yarn path gap 3 of the sewing machine 1a.

The application of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.
For example, it is elastically deformed so as to crush the wide portion 32 of the gap packing material 30 made of an elastically deformable elastic member, and is inserted into the yarn path gap 3 of the sewing machine 1 and inside the yarn path gap 3. The gap packing material 30 may be disposed in the yarn path gap 3 of the sewing machine 1 so that the wide portion 32 swells on the inner side of the sewing machine 1 (sewing machine frame 2) and is restored to its original shape. And the narrow part 33 is formed in the yarn path gap 3 part.
When removing the gap packing material 30 from the yarn path gap 3 of the sewing machine 1, if the gap packing material 30 is pulled strongly, the wide portion 32 is elastically deformed so as to be crushed and removed. Good.

  Further, in the present embodiment, in order to make the width of the yarn path gap 3 and the thickness of the constricted portion of the gap packing material substantially the same width (thickness), the gap packing material is folded in two and overlapped. As described above, the present invention is not limited to this, and according to the thickness of the gap packing material itself and the width of the yarn path gap 3, the gap packing material is arbitrarily folded, depending on the number of laminated layers. A constricted portion may be formed.

  In addition, it is needless to say that other specific detailed structures can be appropriately changed.
