Abstract

(57) [Summary] [Purpose] Perform accurate cutting by eliminating the escape of the circular saw blade. [Structure] A plurality of circular saw blades 1 are arranged next to each other. A spacer 3 is detachably attached between adjacent circular saw blades 1 so as to cover a shaft 2 that rotatably supports each circular saw blade 1. A plurality of spacers 3 are arranged from the shaft 2 toward the outer peripheral end of the circular saw blade 1.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a cutting device that can obtain a plurality of cut objects in a single cutting process by using a plurality of cutting blades.

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, there has been provided a cutting device capable of simultaneously cutting a plurality of thin plate stone materials in one cutting process by cutting a stone material with a plurality of cutting blades. As shown in FIG. 4, a plurality of circular saw blades 1 are arranged side by side next to each other, and the circular saw blades 1 are simultaneously rotated by the shaft 2 to remove the stone a as shown in FIG. By cutting, a plurality of thin stone materials b can be cut out at the same time.

[0003]

[Problems to be solved by the device]

 However, in the conventional example as described above, each circular saw blade 1 is supported only by the spacer 4 provided at the central portion of the circular saw blade 1, so that the circular saw blade 1 is supported. If it hits a hard part of the stone a during cutting, or if the circular saw blade 1 becomes poorly cut, the circular saw blade 1 escapes at the time of cutting, and as shown in FIG. There was a problem of being cut off.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a cutting device capable of performing accurate cutting by eliminating escape of a circular saw blade.

[0005]

[Means for Solving the Problems]

 In the present invention, in order to achieve the above object, a plurality of circular saw blades 1 are arranged side by side so as to be adjacent to each other, and adjacent circular saw blades are provided so as to cover a shaft 2 rotatably supporting each circular saw blade 1. The spacers 3 are detachably attached between the shafts 1, and a plurality of the spacers 3 are arranged from the shaft 2 toward the outer peripheral end of the circular saw blade 1.

[0006]

[Action]

 In the cutting with the circular saw blade 1, the spacers 3 are sequentially removed as the cutting progresses, and the plurality of circular saw blades 1 are arranged from the shaft 2 toward the outer peripheral end of the circular saw blade 1. Since it is supported in the largest possible area by the spacers 3 provided, the escape of the circular saw blade 1 at the time of cutting can be suppressed as much as possible, and accurate cutting can be performed.

[0007]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. As shown in FIG. 1, the cutting device includes a shaft 2 which is rotationally driven by a driving device (not shown), a circular saw blade 1 attached to the shaft 2 so as to be adjacent to the shaft 2, and a circular saw blade 1. The main body is constituted by the spacer 3 provided therebetween. The circular saw blades 1 are juxtaposed at predetermined intervals by spacers 4 attached to the shaft 2. A plurality of circular saw blades 1 are provided from the shaft 2 toward the outer peripheral end of the circular saw blade 1 so as to cover the spacers 4. Spacers 3 are arranged. That is, as shown in FIGS. 2 and 3, the first spacer 3a is provided on the outer surface side of the spacer 4 so as to cover the spacer 4, and the first spacer 3a is provided on the outer surface side of the first spacer 3a more than the first spacer 3a. A second spacer 3b having a large diameter is provided. Each of the spacers 3 is divided into two and is connected together by a fastener 5 such as a bolt, and the fastener 3 can be easily removed from the shaft 2 by removing the fastener 5 and separating the spacers. Reference numeral 6 is a plug for closing the through hole 7 through which the fixing tool 5 is inserted, and is detachably attached to the through hole 7. In the illustrated embodiment, the case where the spacer 3 is the first spacer 3a and the second spacer 3b is shown, but the present invention is not limited to this, and there are two or more spacers. Is also good. In the illustrated embodiment, the circular saw blade 1 has three blades, but it may have three blades or more or three blades or less.

Thus, a plurality of circular saw blades 1 can be used to cut, for example, a stone material as a workpiece to simultaneously cut out a plurality of thin stone materials. When the cutting is started, the circular saw blade 1 is supported by the spacer 4, the first spacers 3a, and the second spacers 3b, and the second spacers 3b located outside are removed as the cutting progresses. As the cutting progresses further, the first spacer 3a is removed, and finally the circular saw blade 1 is supported only by the spacer 4 to complete the cutting. It supports a wide area as much as possible, and can perform accurate cutting without causing escape. Here, since each spacer 3 is divided into two and connected by the fastener 5, the fastener 5 is detached and separated without removing the circular saw blade 1 from the shaft 2 at the time of removal. By doing so, it can be easily removed.

[0009]

[Effect of the device]

 In the present invention, as described above, a plurality of circular saw blades are juxtaposed side by side, and a spacer is detachably attached between the adjacent circular saw blades so as to cover the shaft that rotatably supports each circular saw blade. This spacer is attached to the outer periphery of the circular saw blade from the shaft, so each circular saw blade is cut from the shaft to the outer periphery of the circular saw blade by sequentially removing the spacers as the cutting progresses. The spacers arranged toward the end support the widest possible area, and the cutting of the circular saw blade during cutting can be suppressed as much as possible to achieve accurate cutting.
