Description

[Technical field]

[0001] The present disclosure relates to a shearing device. [Background technology]

[0002] In conventional shearing devices, scraps produced during cutting and work products were allowed to fall freely into the same scrap box and accumulated there. However, when the size of the work products was relatively small and roughly the same size as the scraps, sorting the two products took time and effort to solve the problem. In this case, a technology has been disclosed in which a chute means that can slide downward at an angle is arranged on a linear motion guide on a base frame at the lower front side of the lower blade where the work cutting is performed, in a position that opens a gap dimension for the cut scraps to fall freely, and the chute means can move back and forth with an extendable slide to close the gap dimension (see Patent Document 1).

[0003] [Patent Document 1] JP 2001-077040 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the conventional technology described above, after the workpiece is cut, it is possible to separate the workpiece from the scrap. However, for example, when cutting a long workpiece, there is a risk that the workpiece will sag in the portion that extends beyond the platform on which it is placed. If the workpiece is cut in this state, there is a risk that the workpiece cannot be cut accurately. In addition, when the workpiece is returned to the table by the backgauge after being cut, there is a problem that the backgauge cannot contact the workpiece due to the sagging of the workpiece, and the return movement of the workpiece cannot be performed.

[0005] An object of the present invention is to provide a shearing device that can accommodate a plurality of operations when cutting a workpiece by holding a chute at a plurality of points. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the shearing apparatus of the present invention comprises a mounting table extending substantially horizontally for placing the workpiece thereon, a cutting device arranged at the rear end of the mounting table for cutting the workpiece, a backgage device arranged behind the mounting table for returning the workpiece toward the mounting table, and a chute device, wherein the chute device comprises a lifting device for raising and lowering a chute, and a tilting device for tilting the chute. Effect of the Invention

[0007] According to the shearing device of the present invention, the lifting device and tilting device can hold the chute at a plurality of positions at a predetermined height and tilt, so that any operation can be performed, such as holding the workpiece, sliding it down, returning it, etc. Therefore, a very easy-to-use shearing device can be obtained. [Brief description of the drawings]

[0008] [Figure 1] 1 is a schematic diagram showing an overall configuration of a shearing device in accordance with a first embodiment. [Diagram 2] 1 is a schematic diagram showing a chute device in a first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram showing an overall configuration of a shearing device 1 according to the first embodiment. As shown in Fig. 1, the shearing device 1 has a base 10. On the upper surface of the base 10, a mounting table 11 for mounting a workpiece W thereon is provided so as to extend in a substantially horizontal direction. A cutting device 20 is disposed at the rear end of the mounting table 11 . The cutting device 20 includes an upper blade 21 located above the mounting table 11, and a lower blade 22 fixed below the mounting table 11. The upper blade 21 is normally located above the mounting table 11, and is lowered to the position of the lower blade 22 by operating a cutting drive device (not shown). This allows the workpiece W to be cut.

[0010] A backgage device 30 is disposed behind the mounting table 11. The backgage device 30 is provided with a drive shaft 31 extending in the front-rear direction. A drive member 32 is attached to the drive shaft 31 so as to be movable in the front-rear direction along the drive shaft 31. A back gauge 33 is attached below the driving member 32. The back gauge 33 includes a contact plate 34 facing the mounting table 11.

[0011] Next, the chute device will be described in detail. FIG. 2 is a schematic diagram showing the chute device in this embodiment. 2, the chute device 40 includes a lifting device 41 that is lifted and lowered by, for example, an air cylinder mechanism. The lifting device 41 is operated by, for example, an air cylinder mechanism, and includes a lifting cylinder 42. A chute support member 43 is attached to the top of the lifting device 41. The chute support member 43 is formed so as to extend obliquely upward toward the front. A substantially flat chute 44 is rotatably attached to the upper end portion of the chute support member 43 via, for example, a hinge.

[0012] The upper end of the lifting cylinder 42 is connected to the lower surface side of the chute 44 . As a result, by operating the lifting cylinder 42 of the lifting device 41, the chute 44 can be raised and lowered in the vertical direction while maintaining a horizontal state. In this case, the state in which the height position of the chute 44 is approximately equal to the height position of the mounting table 11 is the uppermost position, and the state in which the height position of the chute 44 is lower than the mounting table 11 is the lowermost position.

[0013] Further, a tilting device 45 is attached to the lifting device 41. The tilting device 45 is operated by, for example, an air cylinder mechanism, and includes a tilting cylinder 46. The chute 44 is connected to the upper end of the tilt cylinder 46 . This allows the tilt of the chute 44 to be varied by operating the tilting cylinder 46 of the tilting device 45. In this case, the state in which the chute 44 is inclined is referred to as the inclined position.

[0014] [1-2. Operation] Next, the operation of the first embodiment will be described. (Shooter movement of workpiece) The shooter operation is an operation that causes the shoot device 40 to function as the shooter 44. In the chute operation, the tilting cylinder 46 of the tilting device 45 is operated downward, whereby the chute 44 rotates about the front end portion, and the rear portion of the chute 44 is held in a tilted position so as to be tilted downward.

[0015] In this state, the workpiece W is placed on the placement table 11, and the worker sends the workpiece W backward, stops the workpiece W at a predetermined position, and operates the cutting device 20. As a result, the upper blade 21 descends to the lower blade 22 portion to cut the workpiece W. The cut workpiece W slides backward along the chute. Thereafter, the worker retrieves the workpiece W that has slid backward.

[0016] (Cutting operation of long workpieces) The cutting operation of the long workpiece W is an operation for supporting the workpiece W when cutting the workpiece W having a large length dimension. In the cutting operation of the long workpiece W, the lifting cylinder 42 of the lifting device 41 is operated to raise the chute 44 while maintaining it in a horizontal position, and the height position of the chute 44 is held in the uppermost position approximately equal to the height position of the mounting table 11.

[0017] In this state, the workpiece W is placed on the placement table 11, and the worker sends the workpiece W backward, stops the workpiece W at a predetermined position, and operates the cutting device 20. As a result, the upper blade 21 descends to the lower blade 22 portion to cut the workpiece W. In this case, since the chute 44 is held at the uppermost position, even when cutting a long workpiece W, the workpiece W can be held by the chute 44, and the workpiece W can be prevented from sagging.

[0018] (Returning movement of the workpiece) The returning operation of the workpiece W is an operation of returning the workpiece W to the mounting table 11 again after the workpiece W has been cut. In the return movement of the workpiece W, the lifting cylinder 42 of the lifting device 41 is operated to hold the chute 44 at the lowest position. In this state, the workpiece W is placed on the placement table 11, and the worker sends the workpiece W backward, stops the workpiece W at a predetermined position, and operates the cutting device 20. As a result, the upper blade 21 descends to the lower blade 22 portion to cut the workpiece W. Thereafter, the worker removes the workpiece W remaining on the mounting table 11.

[0019] Next, the lifting cylinder 42 of the lifting device 41 is operated to lift the chute 44 while keeping it horizontal, and the chute 44 is held at the uppermost position. Thereafter, the backgage device 30 is operated to send the workpiece W remaining on the chute 44 forward by the contact plate 34 of the backgage 33. This causes the cut workpiece W to be returned to the placement table 11.

[0020] As a result, when further cutting is required after cutting the workpiece W, the worker does not have to go around to the rear of the shearing device 1 to retrieve the workpiece W, and the next cutting operation can be performed continuously.

[0021] [1-3. Effects, etc.] As described above, the shearing device 1 of this embodiment extends substantially horizontally and includes the mounting table 11 on which the workpiece W is placed, the cutting device 20 arranged at the rear end of the mounting table 11 and cutting the workpiece W, the backgage device 30 arranged behind the mounting table 11 and returning the workpiece W toward the mounting table 11, and the chute device 40. The chute device 40 includes the lifting device 41 which lifts and lowers the chute 44, and the tilting device 45 which tilts the chute 44.

[0022] As a result, the lifting device 41 and the tilting device 45 can hold the chute 44 at a predetermined height and tilt position, allowing any operation to be performed, such as holding the workpiece W, sliding it down, or returning it. This makes it possible to obtain a shearing device 1 that is extremely easy to use.

[0023] In addition, in the shearing device 1 of this embodiment, the chute device 40 holds the chute 44 in an inclined position by the tilting device 45, and after the workpiece W placed on the mounting table 11 is cut by the cutting device 20, the workpiece W is slid down by the chute 44.

[0024] As a result, by cutting the workpiece W while tilting the chute 44 by the tilting device 45, the cut workpiece W can be slid down to the rear of the shearing device 1 by the chute 44.

[0025] In addition, in the shearing device 1 of this embodiment, the chute device 40 holds the chute 44 at the highest position using the lifting device 41, and performs a long workpiece cutting operation to cut the workpiece W while holding the long workpiece W placed on the mounting table 11 with the chute 44.

[0026] With this, while the chute 44 is held at the highest position by the lifting device 41, the long workpiece W placed on the mounting table 11 is held by the chute 44 and the cutting operation of the long workpiece W is performed, so that cutting can be performed while holding the long workpiece W. Therefore, it is possible to prevent the workpiece W from sagging and to cut the workpiece W accurately.

[0027] In addition, in the shearing device 1 of this embodiment, the chute device 40 holds the chute 44 at the lowest position using the lifting device 41 and cuts the workpiece W placed on the mounting table 11, and then holds the chute 44 at the highest position using the lifting device 41 and returns the workpiece W remaining on the chute 44 to the mounting table 11 using the backgage device 30.

[0028] As a result, the backgauge device 30 can be used to obtain accurate dimensions of the workpiece W, and when the workpiece W remaining in the chute 44 after cutting is to be further cut in the next process, the worker can return the workpiece W to the mounting table 11 without having to go around to the rear of the shearing device 1, thereby enabling efficient cutting work.

[0029] (Other embodiments) As described above, the first embodiment has been described as an example of the technology disclosed in this application. However, the technology of the present invention is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the first embodiment to create new embodiments. [Explanation of symbols]
