Description

  The present invention relates to an ultrasonic cutting apparatus, and more particularly, to a care label for displaying a size or a trademark attached to underwear or a shirt, and a manufacturing apparatus thereof.

  In general, clothes such as underwear and shirts are provided with a care label that indicates washing suitability and size. The care label is generally called a laundry name, and is used to indicate a brand name, a size, a body shape, a washing picture display, a quality or a place of origin, a demerit display or a note based on the product liability law.

  The care label is used by printing display portions on both sides of a strip-shaped fabric and then sewing or welding one side of the strip to the clothing. When there are a lot of written contents, two care labels are sewn or welded, or one relatively long care label is folded in half and sewn or welded to clothing.

  Generally, a care label is a long label fabric or a polyester fabric cut into strips. When the corners of the care label are square, there is a problem that the wearer's skin may get stuck when wearing clothing with a care label or while the wearer is moving, causing discomfort to the wearer. there were. As a solution to this problem, in Japanese Utility Model Registration No. 3098338, a care label is disclosed in which a rounded portion formed by ultrasonic cutting is formed at a corner portion as shown in FIG.

  In order to make the corner portion of the care label round, it is necessary to cut the corner portion of the rectangular cloth label minutely. When a device for cutting a corner portion is incorporated in the care label manufacturing apparatus, there arises a problem that a piece of cloth waste corresponding to the cut corner portion adheres to a blade or a roller.

  In order to remove the adhering piece of cloth waste, as described in JP-A-2006-167994, a label manufacturing apparatus having an ultrasonic horn and a blade facing above or below, A blade or ultrasonic horn provided with a slope and an upper ultrasonic horn provided with an air injection hole has been proposed.

However, even if a slope is provided on the lower ultrasonic horn as in the device described in Japanese Patent Application Laid-Open No. 2006-167994, if the air is not jetted from above, the cloth pieces will slide down the slope sufficiently. There is no possibility. Further, when the blade and the ultrasonic horn are repeatedly contacted for cutting the fabric, the ultrasonic horn may be worn and eventually damaged.

  The problem to be solved by the present invention is to sufficiently remove cloth scraps in an apparatus for manufacturing a care label having a combination of an ultrasonic horn and a blade facing the horn and having a corner cut. And preventing wear and damage of the ultrasonic horn.

  An ultrasonic cutting device according to the present invention includes an ultrasonic horn for generating ultrasonic waves and a blade provided to face the ultrasonic horn, and the ultrasonic horn generates ultrasonic waves close to the blade. It is possible to cut the fabric between the ultrasonic horn and the blade, and the blade is provided with at least one vent hole to solve the above problem.

  Another ultrasonic cutting device of the present invention includes an ultrasonic horn for generating ultrasonic waves and a blade provided to face the ultrasonic horn, and the ultrasonic horn approaches the blade to generate ultrasonic waves. An ultrasonic cutting device capable of cutting a fabric between the ultrasonic horn and the blade when generated, wherein a removable adapter is provided on a surface of the ultrasonic horn facing the blade. By being attached, the above-described problems are solved.

  The ultrasonic cutting device may further include a gas supply pipe provided close to the blade. In the ultrasonic cutting device, the ultrasonic horn is provided below the blade, and the blade moves up and down so that the blade approaches the ultrasonic horn or from the ultrasonic horn. It may be possible to leave.

  The adapter for an ultrasonic horn according to the present invention solves the above problems by being configured to be attached to a surface of the ultrasonic horn facing the blade in an ultrasonic cutting device including the ultrasonic horn and the blade. To do.

  The ultrasonic horn adapter communicates with the vent hole of the ultrasonic horn when the ultrasonic horn is attached to the ultrasonic horn in an ultrasonic cutting device in which the ultrasonic horn has at least one vent hole. It may be provided with at least one vent hole provided in.

  According to the ultrasonic cutting device of the present invention, when a slope is provided in the lower ultrasonic horn, air is injected from the inside of the upper blade or the periphery thereof, thereby generating the care label. The cloth waste piece that slides down the slope more reliably, and the cloth waste piece can be sufficiently removed. Thereby, since it becomes possible to provide an ultrasonic horn only below the apparatus, the entire ultrasonic cutting apparatus can be reduced in size.

  In addition, the ultrasonic horn adapter of the present invention is attached to the ultrasonic horn in the ultrasonic cutting device, thereby preventing wear and damage of the ultrasonic horn due to contact between the blade and the ultrasonic horn when cutting fabric. To do. As a result, the possibility of failure of the ultrasonic cutting device due to damage of the ultrasonic horn is reduced, and the life of the ultrasonic cutting device can be extended.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, a care label manufacturing apparatus is taken up as an example of an ultrasonic cutting apparatus for cutting a cloth by ultrasonic waves, but the present invention is an arbitrary ultrasonic cutting apparatus such as an apparatus for manufacturing a cloth label other than a care label. It can be applied to a device.

  FIG. 1 is a schematic side view showing a care label manufacturing apparatus 100 of the present invention. The care label manufacturing apparatus 100 includes a tape roll 10, transfer rollers 20 and 21, a transfer sensor 30, control units 40 and 41, a clamper 50, a weight 60, a reading sensor 70, blades 80 and 81, Ultrasonic horns 90 and 91 are provided. In addition to the above-described components, the care label manufacturing apparatus 100 may be provided with a straightening heater that stretches the wrinkles of the fabric, a folding portion that folds the cut care label, etc., but these components are omitted for the sake of simplicity. To do.

  The tape roll 10 is obtained by winding a long fabric 11 cut into a belt shape on an arbitrary core. The fabric 11 is cut by the care label manufacturing apparatus 100 and finally becomes the care label 12. The material of the fabric 11 is a fabric made of synthetic fiber or natural fiber, rubber, synthetic resin or the like, but is preferably a woven fabric made of a flat belt-shaped fabric woven with white polyester yarn. Usually, there is a display portion printed with blue, red or black ink on one or both sides of the fabric for producing the care label, but the display portion is omitted in each drawing of this application for the sake of simplicity of explanation. .

  The transfer rollers 20 and 21 are rollers for transferring the fabric 11 in the downstream direction. Preferably, one or both of the rotating bodies are rotated while the fabric 11 is sandwiched, whereby the friction between the rotating body and the fabric 11 is achieved. It is comprised from a pair of rotary body which can pull the fabric 11 downstream.

  The transfer sensor 30 is a sensor that can detect the transfer of the fabric 11 and is provided to stop the operation of the transfer roller 20 when the fabric 11 is not present. Specifically, when the transfer sensor 30 senses the fabric 11, the transfer sensor 30 sends a sensing signal to the control unit 40, and the control unit 40 performs control so that the transfer roller 20 operates. On the other hand, when the transfer sensor 30 does not sense the fabric 11, the transfer sensor 30 sends a non-sensing signal to the control unit 40, and the control unit 40 performs control so that the transfer roller 20 stops. The control of the transfer roller 20 by the control unit 40 may be electrical or mechanical.

  The clamper 50 is an instrument that determines the position through which the fabric 11 passes by sandwiching the fabric 11 being transferred. The weight 60 is a device that applies tension to the fabric 11 in order to facilitate the transfer of the fabric 11. The reading sensor 70 senses whether or not the printing surface of the fabric 11 is correctly printed. When the printing surface of the fabric 11 is not correctly printed, the reading sensor 70 sends an abnormal signal to the control unit 41. When receiving an abnormality signal from the reading sensor 70, the control unit 41 stops the operation of the clamper 50, the transfer roller 21, the blades 80, 81, and the like. The clamper 50, the weight 60, and the reading sensor 70 are not essential components of the present invention, and the object of the present invention can be achieved even when these are not present or when other appropriate alternative means are provided. obtain.

  In addition to the above functions, the control unit 41 has a function of controlling the vertical movement of the clamper 50, the rotation of the transfer roller 21 and the operation interval of the blades 80, 81, etc., and thereby the length of the care label 12 after cutting. Can be adjusted.

  A blade 80 and an ultrasonic horn 90 are provided on the downstream side of the transfer roller 21 so as to face each other. Further, downstream of the blade 80 and the ultrasonic horn 90, a blade 81 and an ultrasonic horn 91 are provided to face each other in the vertical direction. The blades 80 and 81 can move up and down, and move up and down in response to a control signal from the control unit 41. On the other hand, the ultrasonic horn 90 and the adapter 92 attached to the ultrasonic horn 91 are fixedly provided so as to be in contact with the lower surface of the fabric 11.

  The blades 80 and 81 are preferably made of metal and are made of various alloys such as stainless steel (SUS) and chromium molybdenum steel (SCM). The detailed shape and the like of the blades 80 and 81 will be described later.

  The ultrasonic horns 90 and 91 are resonance bodies for transmitting vibration energy to the outside. Usually, ultrasonic waves are generated by resonating mechanical vibrations converted by a vibrator from an ultrasonic signal generated by an oscillation circuit. It is issued outside. The ultrasonic horns 90 and 91 are preferably made of metal, and an aluminum alloy, a titanium alloy, die steel or the like is used as the material thereof. The illustration of the oscillation circuit and the vibrator provided inside or outside the ultrasonic horns 90 and 91 is omitted.

  In the present embodiment, all ultrasonic horns that have conventionally been installed at the upper side are installed at the lower side, thereby realizing downsizing of the care label manufacturing apparatus. This is a component that requires a large installation space for the ultrasonic horn, including its associated devices (oscillation circuits, vibrators, etc.). By not installing the ultrasonic horn upward, the installation space above the care label manufacturing device is greatly increased. This is because it can be reduced.

  When the ultrasonic wave is emitted from the ultrasonic horn 90 in a state where the blade 80 moves downward and has a slight gap with the fabric 11, the vibration is transmitted to the blade 80 and the fabric 11 is cut. Similarly, when the ultrasonic wave is emitted from the ultrasonic horn 91 in a state where the blade 81 moves downward and has a slight gap with the fabric 11, the vibration is transmitted to the blade 81 and the fabric 11 is cut. . The amplitude values of the ultrasonic horns 90 and 91 are preferably 70 to 80 microns.

  In the care label manufacturing apparatus 100, the blade 80 and the ultrasonic horn 90, or the blade 81 and the ultrasonic horn 91 are designed not to contact directly or indirectly with the cloth 11 interposed therebetween. In operation, they often come into direct or indirect contact. In particular, when an ultrasonic horn and its associated devices (oscillation circuit, vibrator, etc.) are provided above, the ultrasonic horn itself and the blade are often damaged by the weight. In the present invention, an ultrasonic horn having a large weight is installed below and an adapter 92 described later is attached to solve the problem of wear and damage caused by contact between the blade and the ultrasonic horn.

On the other hand, a gas supply pipe 221 is attached behind the blade 81, and a gas supply pipe 220 is connected to the gas supply pipe 221. The gas supply pipes 210 and 220 are pipes for sending air to the blade 80 and the gas supply pipe 221, respectively. The gas supply pipes 210, 220, and 221 are made of any material such as metal, synthetic resin, rubber, or a combination thereof. One end of each of the gas supply pipes 210 and 220 is connected to a compressed air supply device including a liquid nitrogen cylinder and the like. Further, the supply timing of the compressed air to the gas supply pipes 210 and 220 can be controlled by the control unit 41.

  The ultrasonic horn 90 is provided with slopes 230 and 231. The slopes 230 and 231 are for sliding the cloth pieces downward by the gas jet from the blade 80. Similarly, the ultrasonic horn 91 is provided with slopes 240 and 241. The slopes 240 and 241 are for sliding the cloth waste pieces downward by the ejection of gas from the gas supply pipe 221.

The support 304 is a support base for the cutting blade 301 provided to facilitate the handling of the blade 80, and is usually the same material as the cutting blade 301 and is integrally formed with the cutting blade 301. Yes.

  The vent holes 302 and 303 are tunnel-shaped holes provided in the blade 80 for allowing the air supplied from the air supply pipe 210 to pass downward. As shown in FIG. 3B, the vent holes 302 and 303 are connected to the upper vent hole 310. The vent hole 310 is connected to the air supply pipe 210, and the air supplied to the vent hole 310 is jetted downward through the vent holes 302 and 303. In FIG.3 (b), a dotted line part shows the shape of the vent holes 302 and 303 which cannot be seen from a side surface. FIG. 3C is a cross-sectional view taken along the line AA ′ of FIG. 3A, and it can be seen that the vent hole 310 is connected to the vent holes 302 and 303 and continues to the lower part of the blade 80. The shape of the outside and the inside of the blade 80 is an example, and in practice, any shape that can cut the fabric and has a vent hole for blowing away the waste cloth pieces from the top to the bottom can be used. .

FIG. 4 is a view showing the external appearance of an ultrasonic horn 91 to which an adapter 92 according to the present invention is attached, and a blade 81 provided opposite to the ultrasonic horn 91. 4, (a) is a bottom view of the blade 81, (b) is a rear view showing the appearance of the gas supply pipes 220, 221 provided on the back surface of the blade 81,
(C) The front view of the ultrasonic horn 91 with which the adapter 92 was mounted | worn (a back view is also the same). Here, the surface facing the direction in which the fabric 11 flows is the front.

  The blade 81 shown in FIG. 4A is a blade having a known shape, and includes a cutting blade portion 450 and a support portion 460. The shape of the blade 81 is substantially the same as that of the blade 80 described above in which the vent holes 302, 303, 310 are not provided. Instead of providing a vent hole in the blade 81, a gas supply pipe 221 is provided on the back as shown in FIG. When compressed gas is supplied to the gas supply pipe 220 connected to the gas supply pipe 221, the compressed gas flows into the gas supply pipe 221, and gas is injected from below the gas supply pipe 221. The gas supply pipe 221 may be provided so as to inject gas under the blade 81 in the vicinity of the blade 81, and may not be completely fixed in relation to the blade 81. On the other hand, as shown in FIG. 4C, an adapter 92 is attached to the upper surface 430 of the ultrasonic horn 91. Details of the shape of the adapter 92 will be described later.

  FIG. 5 is a diagram showing the side, top and bottom surfaces of the ultrasonic horn adapter 92 according to the present invention. The adapter 92 has a bottom surface 501 having a shape suitable for the ultrasonic horn 91 and is attached to the upper surface 430 of the ultrasonic horn 91 by any method that does not easily peel off, such as adhesion or caulking. The adapter 92 includes slope portions 510 and 511 that are inclined so that the cloth scraps can easily slide down.

  The material of the adapter 92 is preferably a metal. For example, an aluminum alloy, a titanium alloy, die steel, or the like is used in the same manner as the ultrasonic horns 90 and 91. By attaching the adapter 92 to the ultrasonic horn 91, wear and damage due to contact with the fabric 11 and the blade 81 on the fabric 11 are primarily caused on the upper surface 502 of the adapter 92, and as a result, the ultrasonic horn 91.
