Abstract

PURPOSE:To provide the title method wherein cutting work can be done without spoiling touch and smoothly when a workpiece made of laminated blanket fabric using Mayer knitting-made blanket fabric is cut. CONSTITUTION:This method is as follows, that is to say, an upper workpiece 16 made of blanket fabric and a lower a workpiece 17 made of blanket fabric are formed of Mayer knitting fiber with synthetic fiber piles, and a workpiece 25a made of laminated blanket fabric, in which each of zigzag heaters 22 is individually arranged parallel to each other between these upper and lower workpieces 16, 17, is divided by cutting. An adhesive is coated in the shape of a band at the space between these upper and lower workpieces 16, 17, at which they are divided by cutting, and they are joined. A joined part 21a in the shape of the band is cut parallel to the joined part 21a by a rotary cutting edge 12, in order that the workpiece 25a is traversed. For that reason, such a trouble as fiber like stringiness coils around the rotary cutting edge 12 does not occur and cutting work can be smoothly done.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transversely cutting a laminated blanket for an electric blanket using a Meyer knitted blanket.

[0002]

2. Description of the Related Art The construction of a conventional electric blanket and its manufacturing method will be described below with reference to FIGS.

As shown in FIG. 4, an electric blanket is a Meyer upper blanket 2 having fluffs 2a made of synthetic fibers such as polyester and acrylic, and a Meyer lower blanket 3 having the fluffs 3a.
To form a layered blanket 1, and a space-shaped groove 5 formed between the upper Meyer blanket 2 and the lower Meyer blanket 3 is provided with a string-shaped heater 4 wired in a zigzag shape. Further, as shown in FIG. 3, in the manufacturing process, the layered blanket 1 is composed of continuous cloth, and the heater 4 is wired as a unit for every one sheet at a constant interval, and between the heater 4 and the next heater 4. The electric blanket is manufactured by cutting the electric blanket.

As shown in FIG. 5, an edge blanket 1a and a cord port 1b are connected to one sheet of electric blanket obtained by cutting a continuous long overlapped blanket 1 as shown in FIG. It is finished in a blanket.

Next, FIG. 6 is taken as an example of a lateral blanking device for cutting a layered blanket for cutting into one electric blanket described above, taking the configuration as shown in, for example, Japanese Patent Publication No. 56-27257. It will be explained based on

In the figure, 6 and 6a are a pair of lower bases provided at intervals a, 8 is a heating convex type which is heated by a heating element 9, and convex portions 7 and 7a are provided at positions facing the lower bases 6 and 6a. However, it is configured to be movable up and down by a cylinder.

In the above structure, the layered blanket 1 is inserted between the lower table 6, 6a and the convex portion 7, 7a of the heating convex mold 8,
With the heating element 9 being energized, the heating convex mold 8 is lowered by a cylinder, and the overlapped blanket 1 is sandwiched between the lower bases 6, 6a and the convex portions 7, 7a to apply heat and pressure. The blanket 2 and the lower Meyer blanket 3 are melted, mixed, and joined. When the layered blanket 1 is taken out in this joined state, the melted synthetic fibers are cooled and hardened, so that the joined portion 10 becomes hard. In addition, the joining portion 10 is provided here by overlapping the hem cloth 1a in the next step.
Layered blanket 1 when sewing around the sewing machine
This is because the surroundings do not stretch due to the tension of the feed applied to, and the appearance is maintained.

Next, the device section for cutting the above-mentioned layered blanket 1 will be described. That is, 11 is a motor, 12
Is a rotary blade rotated by the motor 11, 13 is a moving table for moving the motor 11 and the rotary blade 12 in the front-back direction,
14 is a wheel attached to the moving base 13, and 15 is a wheel 1.
4 is a moving rail.

In order to transversely cut the laid blanket 1 into a single blanket with the above construction, the lower bases 6 and 6 are first operated by the action of the cylinder.
a and the convex portions 7, 7a of the heating convex mold 8 sandwich the overlapping blanket fabric 1 so as not to move, and then the motor 11 rotates the rotary blade 1
2 is rotated, the moving base 13 is moved along the rail 15 in the front-back direction (the direction of the arrow in FIG. 7), and the overlaid blanket 1 is cross-cut. At this time, since the heating element 9 is energized at the same time, if the upper Meyer blanket 2 and the lower Meyer blanket 3 are hot pressed as described above, the material of the layered blanket 1 is made of synthetic fibers such as acrylic and polyester. Therefore, it melts and joins. However, although the horizontal cutting and the joining by the heat and pressure are performed in this manner, the actual joining is performed only at the joining portion 10 which is in contact with the lower bases 6 and 6a and the convex portions 7 and 7a. As shown, the place where the rotary blade 12 cuts the overlaid blanket 1 was not hot pressed.

[0010]

However, as described in the above-mentioned prior art, when the layered blanket 1 is cut, the lower bases 6 and 6a and the convex portions 7 and 7a are heated and pressed linearly at two locations. The heat-pressed portion has a problem that the fluffs 2a and 3a on the surface of the blanket that improve the texture of the blanket are melted and disappear, and the feel is deteriorated.

Further, since the rotary blade 12 cuts not the joint portion 10 but the overlapped portion of the simple overlapping blanket 1, the soft fibers are bitten by the rotary blade 12 and become smooth like thread pulling. There was a problem that cutting work could not be done.

The present invention solves the above problems, and when cutting a layered blanket using a Mayer blanket material made of synthetic fiber, it is possible to perform a smooth cutting operation without impairing the texture and for a blanket for an electric blanket. It is intended to provide a method for transversely cutting blankets.

[0013]

[Means for Solving the Problems] The technical solution of the present invention for achieving the above object comprises an upper blanket fabric and a lower blanket fabric fabric composed of Meyer knitted fibers having fluff made of synthetic fibers. When dividing and cutting the stacked blanket fabric in which the jagged heaters are juxtaposed between the upper blanket fabric and the lower blanket fabric fabric, respectively, Adhesive is applied in a band shape between the original fabric and the lower blanket fabric and joined, and the band-shaped joint is cut along the joint with the rotary blade so as to cross the overlapped blanket fabric. Is.

[0014]

According to the present invention, no adhesive is applied to the surface of the woven blanket fabric and the fluff is not cured by the above-mentioned technical means. In addition, since the rotary blade cuts the joint where the adhesive is applied, the upper blanket cloth and the lower blanket cloth are firmly joined, and when cutting, fibers are wrapped around the rotating blade like a thread pull. It can be cut smoothly and beautifully.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The description of the same parts of the horizontal blanking device for electric blankets and overlapping blankets as in the conventional example will be omitted.

FIG. 2 is a diagram showing a flow of a manufacturing process of an electric blanket made of a layered blanket according to the present invention. 1 in the figure
6 and 17 are made of synthetic fibers such as acrylic and polyester,
In addition, there are a Meyer upper blanket fabric and a Meyer lower blanket fabric that have fluff made of a Meyer knitted blanket. The Meyer upper blanket fabric 16 and the Meyer lower blanket fabric 17 are shown in FIG.
As shown in (a), it is supplied to the process A by the roll 20 at a constant interval.

First, in the process A, the Meyer upper blanket material 1
6 and the Meyer lower blanket fabric raw material 17 by the cutting portion adhesive applying means 29 such as a spray, as shown in FIG. 2B, the cutting portion adhesive 21 is equal to the width of the Mayer lower blanket fabric raw material 17. After being applied in a strip shape, the groove adhesive applying means 18 applies a plurality of adhesive agents 19 linearly to the original Mayer blanket fabric material 17. Next, in the step B, the heater supply means 23 in which the heater wire 22 is arranged in a zigzag shape is supplied between the Mayer upper blanket fabric raw material 16 and the Mayer lower blanket fabric raw material 17. Subsequently, in the step C, the Meyer upper blanket fabric 16 and the Meyer lower blanket fabric 17 and the heater wire 22 and the heater supply unit 23 interposed between the two fabrics 16 and 17 are pressed together by the pressurizing unit 24. ..

At this time, when the pressure is applied by the pressing means 24 in the step C, the heater wire 2 is inserted into the groove having the plurality of linear adhesives 19.
The two are fitted together, and the adhesive 21 for the cutting portion also simultaneously adheres the lateral cutting portion for cutting into one blanket in a later step. Next, in step D, as shown in FIG. 2B, the heater supply means 23 is divided into two parts, which are removed from between the original webs 16 and 17 in the directions of arrows A and B.

Next, referring to FIG. 1, a so-called post-process transverse cutting device for transversely cutting one electric blanket 25 will be described. Reference numeral 11 is a motor, 12 is a rotary blade rotated by the motor 11, 13 is a moving base for moving the motor 11 and the rotary blade 12 in the front-rear direction, 14 is a wheel attached to the moving base 13, 15 is a rail 15 on which the wheel moves. Is.

That is, the continuous blanket blank 25a
When the electric blanket 25 is cut by cutting it horizontally, the cylinder 26 acts to lower the bases 6 and 6a and the convex portions 28 of the convex mold 27.
The piled blanket fabric 25a is sandwiched by 28a so as not to move, and the rotary blade 12 is rotated by the motor 11 to move the moving table 13 in the front-rear direction along the rail 15 to remove the piled blanket fabric 25a. Disconnect. At this time, the cutting portion adhesive 21 is applied between the upper Mayer blanket fabric raw material 16 and the Mayer lower blanket fabric raw material 17 to cut the band-shaped joint portion 21a which is bonded to each other.

As described above, the continuous blanket blank 25a
No adhesive is applied to the surface of the electric blanket 25 because the adhesive is applied only between the Mayer's upper blanket material 16 and the Mayer's lower blanket material 17 which are individually cut. Moreover, since heat and pressure are not required, the fluff on the surface of the blanket which improves the feel of the skin is not hardened. Therefore, the electric blanket 25 having a good feel can be provided. Also, the rotary blade 1
2 cuts the joining portion 21a of the Mayer upper blanket material 16 and the Mayer lower blanket material 17 to which the adhesive 21 for the cutting portion is applied, so that a fiber like a thread-drawing that has been conventionally seen is applied to the rotary blade 12. It is possible to perform the cutting work smoothly without getting entangled.

[0022]

As is apparent from the above description, according to the method for transversely cutting a layered blanket for an electric blanket of the present invention, an adhesive is formed in a strip shape between the Mayer upper blanket and the Mayer lower blanket. Since the composition is applied and cut along the portion so as to cross the original blanket fabric with a rotary blade, the following effects are obtained. (1) Since no adhesive is applied to the surface side having fluffs or a heating convex mold is pressed against the fluffy surface, a blanket with a good texture can be provided without curing the fluffs. (2) Since the rotating blade cuts the hardened part of Meyer's upper blanket fabric and the lower blanket fabric by adhesive bonding, the fibers do not cling to the rotating blade like threading at the time of cutting. Can perform cutting work.
