The operation of the above cutting apparatus 10 will be described.
First, a user (hereinafter simply referred to as “user”) of the cutting apparatus 10 of the present invention performs initial setting via an operation means (not shown) such as an operation panel or a personal computer.
In this embodiment, as the adhesive sheet AS, the base sheet BS can be easily cut at any temperature between 35 ° C. and 80 ° C., and the adhesive AD layer can be arbitrarily selected between minus 15 ° C. and 10 ° C. Suppose that the thing of the characteristic which becomes easy to cut | disconnect under temperature is employ | adopted.
In consideration of the above-described characteristics of the adhesive sheet AS in the initial setting, the user changes the first temperature changing means 40 to the first temperature (for example, the first cutting region 21 </ b> A at an arbitrary temperature between 35 ° C. and 80 ° C. (for example, 40 ° C.) and the second temperature changing means 50 is set to a second temperature (for example, 2 ° C.) that is an arbitrary temperature between −15 ° C. and 10 ° C. in the second cutting region 21B. Then, after inputting data to the cutting device 10 via an operating means (not shown), a signal for starting automatic operation is input. Then, the moving means 30 drives the articulated robot 31 and the chuck motor 33 to support the cutter blade 21 stored in a predetermined storage position (not shown) with the chuck 33A, and then to the detection position of a cutting means detection means (not shown). The cutter blade 21 is arranged, and the cutting means detection means (not shown) stops in a state where the position of the recess 21C, the position of the cutting edge 21D, the position of the blade edge 21E, and the abnormality of the cutter blade are detected, and enters a standby state (hereinafter, referred to as "cutting edge"). This state is simply called “standby state”).
The moving means 30 cuts at the position where the cutting edge 21D is pierced, the position where the concave portion 21C is disposed, and the blade edge 21E with respect to the adhesive sheet AS to be cut based on the detection result of the cutting means detection means (not shown). The operation of the articulated robot 31 is automatically corrected so that the trajectory to be performed is a predetermined position, a predetermined trajectory, and the like. Accordingly, even if the cutter blade 21 is displaced and supported by the chuck motor 33, the adhesive sheet AS can be cut into a predetermined shape.

  Then, when the integrated object WK1 is placed by a user or a conveying means (not shown) such as an articulated robot or a belt conveyor so that the adhesive AD layer is on the supporting surface 61A side, the cutting object supporting means 60 is The decompression means (not shown) is driven to start sucking and holding the integrated object WK1. Next, the second temperature changing means 50 drives the heating / cooling means 51, and the groove space SP surrounded by the groove 61B and the adhesive AD layer becomes a temperature between minus 15 ° C. and 10 ° C. (for example, 2 ° C.). As described above, the temperature of the groove space SP is changed. Thereafter, the moving means 30 drives the articulated robot 31, and based on the detection result of the cutting means detecting means (not shown), the bottom of the recess 21C is bonded to the base sheet BS as shown in FIG. The cutter blade 21 is pierced into the adhesive sheet AS so as to be disposed at the boundary with the agent AD layer, and most of the second cutting region 21B enters the groove space SP. At this time, the angle of the outer edge of the recess 21C for cutting the base sheet BS and the angle of the outer edge of the recess 21C for cutting the adhesive AD layer are both set to the angle α1, but in some cases, the cutter The inclination of the blade 21 may be changed, and the base sheet BS and the adhesive AD layer may be cut at an angle other than the angle α1. Next, the first temperature changing means 40 drives the heating and cooling means 41 so that the first cutting region 21A has a first temperature (for example, 40 ° C.) that is an arbitrary temperature between 35 ° C. and 80 ° C. The temperature of the first cutting region 21A is changed. The second cutting region 21B that has entered the groove space SP approaches the temperature in the groove space SP and changes to a second temperature (eg, 2 ° C.) that is an arbitrary temperature between −15 ° C. and 10 ° C. Be warmed.

  Then, a first cutting area temperature detecting means (not shown) such as a temperature sensor or a thermo camera detects that the first cutting area 21A has been changed to the first temperature, and the second cutting area 21B has the second temperature. When a second cutting area temperature detecting means (not shown) such as a temperature sensor or a thermo camera detects that the temperature has been changed to, the moving means 30 drives the articulated robot 31 and moves the cutter blade 21 along a predetermined trajectory. Then, the adhesive sheet AS is cut into a predetermined shape by the blade edge 21E (the outer edge portion of the recess 21C). Thereby, the adhesive sheet AS is continuously cut by forming a cut through the adhesive sheet AS, and when the cutting of the adhesive sheet AS is completed, the moving means 30 drives the articulated robot 31; It will be in a standby state again. Next, after the cutting object support unit 60 stops driving the decompression unit (not shown), the user or the conveyance unit (not shown) separates the adherend WK to which the adhesive sheet AS cut into a predetermined shape is attached. The adhesive sheet AS remaining on the support surface 61A is removed from the support surface 61A, and the same operation is repeated thereafter.

  Here, when the cutting means detecting means (not shown) detects that the cutter blade 21 supported by the chuck motor 33 is abnormal in the standby state, the moving means 30 is moved to the articulated robot. 31 and the chuck motor 33 are driven, and the cutter blade 21 supported by the chuck motor 33 is discarded in a collection box (not shown), and then another cutter blade 21 stored in a predetermined storage position (not shown) is attached to the chuck 33A. Support and go into standby again.

  According to the embodiment as described above, the cutter blade 21 configured as a single unit is divided into the first cutting region 21A and the second cutting region 21B, and each cutting region is changed to an appropriate temperature. Even if the temperature at which AS can be satisfactorily cut between the base sheet BS and the adhesive AD layer is different, the adhesive sheet AS can be cut satisfactorily.

The base sheet BS side may be cut with the first cutter blade 21H after cutting the side, and when viewed from the X-axis direction in FIG. 2, the first cutter blade 21H and the second cutter blade 21L are mutually connected. The cutting edges 21D may be in contact with each other, or the cutting edges 21D may be separated from each other.

The cutting means 20 is configured to cut the object to be cut into a predetermined shape with a heating wire such as a rotary cutter blade, a perforated rotary cutter blade, a nichrome wire or a wire, instead of or in combination with the cutter blades 21, 21H and 21L. Alternatively, the cutter blade 21 may be pierced into the adhesive sheet AS from below in FIG. 1 to cut the adhesive sheet AS, or the cutter blade 21 in which the recess 21C is not formed may be employed. One having a plurality of recesses 21 </ b> C formed in one cutter blade 21 may be employed. In addition, when the thing in which the several recessed part 21C was formed in the one cutter blade 21 as a cutting | disconnection means 20 is employ | adopted, when it will be in a standby state, abnormality of the cutter blade has generate | occur | produced in the recessed part 21C of the cutter blade 21. When the cutting means detecting means (not shown) detects this, the cutting apparatus 10 automatically operates the articulated robot 31 so as to cut the adhesive sheet AS from the next time in another recess 21C in which no abnormality of the cutter blade has occurred. You may make it correct | amend.

The first cutting region 21A and the second cutting region 21B are mutually connected. The adhesive sheet AS portion left uncut by the blade edge 21E is cut by the second blade edge 21F while effectively suppressing the thermal interference. Further, the cutter blades 21Q and 21S are each formed with a substantially triangular recess 21C in which one corner (the right corner in FIG. 3) is not in contact with each other, and the first cutting region 21A and the second cutting region 21B. While effectively suppressing mutual heat interference, the thickness of the adhesive sheet AS portion left to be cut by the blade edge 21E is made as thin as possible, and the left left adhesive sheet AS portion is cut by the second blade edge 21F. . Further, the cutter blade 21T is formed with a substantially triangular recess 21C that does not require the second blade edge 21F while effectively suppressing mutual thermal interference between the first cutting region 21A and the second cutting region 21B. ing. The cutting means 20 may employ a cutter blade that is in contact with the non-contact corner (right corner) indicated by the cutter blades 21Q and 21S.

What makes it easy to cut | disconnect at 50 degreeC may be employ | adopted, and the cutting devices 10 and 10A of this invention are the temperature which changes the temperature of the 1st cutting area | region 21A and the 1st cutter blade 21H by the 1st temperature change means 40 and 40A. The temperature at which the second cutting region 21B and the second cutter blade 21L are changed by the second temperature changing means 50, 50A is determined in consideration of the temperature at which the base sheet BS and the adhesive AD layer are easily cut. Can be set arbitrarily.
The adhesive sheet AS is illustrated as an object to be cut, and one surface side is described as the base sheet BS, and the other surface side is described as the adhesive AD. However, the cutting apparatus of the present invention can cut any object to be cut. The one surface side and the other surface side are arbitrarily selected depending on the configuration of the cutting object, and the cutting object is not a laminate such as the adhesive sheet AS but a single body. Even if it is a thing, it can respond, if the temperature which can cut | disconnect favorably by the one surface side and the other surface side differs.
As described above, when the adhesive sheet AS in which one surface side is configured by the base material sheet BS and the other surface side is configured by the adhesive AD layer as described above is employed, the base material sheet BS is heated. It becomes soft and becomes easy to cut | disconnect, and it becomes easy to cut | disconnect the adhesive agent AD layer because it hardens | cures by cooling and it becomes difficult to adhere to the cutter blade 21. Further, as a cutting object, for example, when a cleaning brush or a sole of a shoe in which one side is made of rubber and the other side is made of sponge is adopted, the rubber and the sponge are heated. Although it becomes soft and easy to cut, if the sponge is heated at the same temperature as rubber, the sponge melts and adheres to the cutter blade 21, making it difficult to cut. Therefore, the sponge is heated lower than rubber. Thereby, it becomes easy to cut | disconnect by becoming difficult for sponge to adhere to the cutter blade 21. FIG. Furthermore, as the cutting object, for example, a double-sided adhesive sheet in which one surface side is constituted by a first adhesive layer and the other surface side is constituted by a second adhesive layer different from the first adhesive layer is employed. In this case, the first adhesive layer and the second adhesive layer are hardened by cooling and become difficult to adhere to the cutter blade 21, so that the first adhesive layer and the second adhesive layer are easily cut. Since the curing temperature may be different, the cooling temperature may be changed between the first adhesive layer and the second adhesive layer.
The base sheet BS may be easily cut by being softened, or may be easily cut by being hardened.
The adhesive AD layer may be easily cut by being cured, or may be easily cut by being softened, or may be easily attached to the cutter blade 21 or cut regardless of being difficult to attach. It may be easy.
The object to be cut may be changed in temperature to cause some kind of change such as softening, hardening, chemical change, composition change or tissue change, or it may be easy to cut without causing any change.

  The material, type, shape, etc. of the object to be cut and the adherend WK in the present invention are not particularly limited. For example, the object to be cut and the adherend WK may be circular, oval, polygonal, such as a triangle or a quadrangle, and other shapes. When the object to be cut is an adhesive sheet AS, pressure-sensitive adhesiveness, An adhesive form such as heat-sensitive adhesiveness may be used. In addition, such an adhesive sheet AS is, for example, a single layer composed of only an adhesive AD layer, one composed only of a base sheet BS and an adhesive AD layer, a base sheet BS and an adhesive AD layer, It may be one layer or two or more layers, such as those having an intermediate layer between them, and those having an intermediate layer between adhesive AD layers. Examples of the object to be cut and the adherend WK include, for example, foods, resin containers, semiconductor wafers such as silicon semiconductor wafers and compound semiconductor wafers, information recording substrates such as circuit boards and optical disks, glass plates, steel plates, earthenware, and wood plates. It may be a simple substance such as paper, rubber, or resin, or may be a composite formed of two or more of them, and any form of member or article can be targeted. In addition, the adhesive sheet AS is replaced with a functional and intended reading, for example, any information label, decorative label, protective sheet, dicing tape, die attach film, die bonding tape, recording layer forming resin sheet, etc. Arbitrary sheets, films, tapes and the like can be attached to any adherend as described above.

  The drive device in the embodiment employs an electric device such as a rotation motor, a linear motion motor, a linear motor, a single-axis robot, and an articulated robot, an actuator such as an air cylinder, a hydraulic cylinder, a rodless cylinder, and a rotary cylinder. In addition, a combination of them directly or indirectly can be adopted.
