Description

Technical Field

[0001] The present invention relates to a cutting waste removing device for removing cutting waste generated when a product sheet is cut.

Background Art

[0002] There is a device called a slitter that winds up a product sheet obtained by continuously cutting a continuous sheet-like long roll (sheet material) such as paper, film, or metal foil into an arbitrary longitudinal width while unwinding it.

[0003] The slitter has a winding shaft for winding up the product sheet after cutting. The cutting waste that is not used as the product sheet falls directly to the floor without being wound up and needs to be removed separately by an operator.

[0004] Therefore, as a means for removing the ear end cutting waste among the cutting waste of the sheet material, there is a removal method in which the ear end of the sheet material cut by the slitter is discharged to the side in the conveyance direction of the sheet material and guided to a crusher for crushing (for example, see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0006] In such a cutting waste removal method, there is a problem that the ear end of the cut sheet material cannot be removed unless it is in a continuous tape shape.

[0007] Also, in the slitter, the sheet material may be cut into a plurality of sheets and wound up simultaneously as a plurality of product sheets. In such cases, there was a problem in that the cutting waste generated when cutting the sheet material into multiple pieces could not be removed by simply removing the edges of the sheet material.

[0008] This invention has been made in view of these problems, and aims to provide a cutting debris removal device that can remove cutting debris generated when a sheet material is cut and wound up in a slitter. [Means for solving the problem]

[0009] The present invention has been made to solve at least some of the above-mentioned problems and can be realized in the following application examples. The reference numerals and supplementary explanations in parentheses in this section are provided to aid in understanding the present invention and correspond to the embodiments described later; they do not limit the present invention in any way.

[0010] [Application Example 1] The cutting debris removal device (1) described in Application Example 1 is A cutting debris removal device (1) installed in a slitter to remove cutting debris generated when cutting sheet material, A removal unit (10) for removing the aforementioned cutting debris, The removal section (10) is moved by a horizontal sliding section (50) that moves the removal section (10) inside the slitter in a direction that crosses the conveying direction of the sheet material and horizontally with respect to the contact surface of the slitter, The gist of it is that it is equipped with the following features.

[0011] In such a cutting debris removal device (1), the removal unit (10) is moved inside the slitter in a direction that crosses the conveying direction of the sheet material and horizontally with respect to the contact surface of the slitter.

[0012] This allows for the removal of not only cutting waste generated at the edges of the sheet material, but also cutting waste generated when the sheet material is cut into multiple pieces. Furthermore, if the sheet material is wound on a paper tube, it can remove paper dust generated during the attachment and detachment of the paper tube.

[0013] [Application Example 2] The cutting debris removal device (1) described in Application Example 2 is the cutting debris removal device (1) described in Application Example 1, The removal section (10) is A wind power generating unit (20) that generates wind power to remove the aforementioned cutting debris, A duct section (30) connected to the wind power generation section (20) and A nozzle portion (40) is attached to the duct portion (30), The gist of it is that it is equipped with the following features.

[0014] In this type of cutting debris removal device (1), the cutting debris can be efficiently removed via the duct section (30) and nozzle section (40) by the airflow generated in the airflow generation section (20).

[0015] In other words, when the wind power generating unit (20) is used as a suction device (20), the suction force of the suction device (20) sucks in the surrounding air from the nozzle unit (40) and also sucks up and removes the cutting debris.

[0016] When a blower (20) is used as the wind power generating unit (20), the wind generated by the blower (20) passes through the duct (30) and is discharged from the nozzle (40), thereby blowing away and removing the cutting debris from the slitter installation site.

[0017] In this way, by drawing in or discharging air from the nozzle (40) and moving the nozzle (40) horizontally, it is possible to remove cutting debris generated when the sheet material is cut vertically in order to wind up multiple product sheets from the sheet material, as well as cutting debris from the edges of sheet material that are not in a continuous tape shape.

[0018] [Application Example 3] The cutting debris removal device (1) described in Application Example 3 is the same as the cutting debris removal device (1) described in Application Example 2, The gist of the invention is that it includes multiple nozzle sections (40).

[0019] In such a cutting waste removing device (1), a plurality of nozzle parts (40) are attached to the duct part (30).

[0020] That is, when the nozzle part (40) is attached to an end part of the duct part (30) close to the slitter grounding surface and at a position corresponding to the height of various rollers in the middle of the slitter line, the cutting waste that has fallen to the grounding surface and the cutting waste attached to various rollers can be removed simultaneously.

[0021] [Application Example 4] The cutting waste removing device (1) described in Application Example 4 is the cutting waste removing device (1) described in Application Example 1, where the removing part (10) is mainly characterized by including a broom part (70) for sweeping out the cutting waste.

[0022] In such a cutting waste removing device (1), the broom part (70) moves horizontally by a horizontal slide part (50). Thereby, for winding up a plurality of product sheets from a sheet material, even the cutting waste generated when the sheet material is cut in the longitudinal direction and the cutting waste at the ear end part of the sheet material that is not in a continuous tape shape can be removed by sweeping it out from the installation location of the slitter.

[0023] [Application Example 5] The cutting waste removing device (1) described in Application Example 5 is the cutting waste removing device (1) described in Application Example 4, and is mainly characterized by including a plurality of broom parts (70).

[0024] In such a cutting waste removing device (1), a plurality of broom parts (70) are attached to the horizontal slide part (50). That is, when the broom part (70) is attached to a position where the cutting waste that has fallen to the slitter grounding surface can be swept out and at a position corresponding to the height of various rollers in the middle of the slitter line, the cutting waste that has fallen to the grounding surface and the cutting waste attached to various rollers can be swept out simultaneously from the slitter installation location, and the cutting waste can be removed efficiently. [Brief explanation of the drawing]

[0025] [Figure 1] This is an external view showing the schematic shape of the cutting debris removal device in the first embodiment. [Figure 2] This diagram shows the general shape of the nozzle section and the connection between the duct section and the nozzle section. [Figure 3] This is an external view showing the schematic shape of the cutting debris removal device in the second embodiment. [Modes for carrying out the invention]

[0026] The embodiments to which the present invention is applied will be described below with reference to the drawings. However, the embodiments of the present invention are not limited to those described below, and can take various forms as long as they fall within the technical scope of the present invention.

[0027] [First Embodiment] The configuration of the cutting debris removal device 1 will be described based on Figures 1 and 2. Figure 1 is an external view showing the general shape of the cutting debris removal device 1 in the first embodiment (Figure 1(A) is a front view, Figure 1(B) is a left side view, and Figure 1(C) is a top view). Figure 2 shows the general shape of the nozzle section 40 and the connection state between the duct section 30 and the nozzle section 40.

[0028] As shown in Figure 1, the cutting debris removal device 1 comprises a removal section 10 consisting of a wind power generation section 20, a duct section 30, a nozzle section 40, a horizontal sliding section 50, and a frame 60. The wind power generation unit 20 is the part that generates wind power, and in this embodiment, a suction device 20 with a built-in fan is used, with the suction side of the suction device 20 connected to the duct unit 30.

[0029] The duct section 30 is a cylindrical tube made of plastic, which is long vertically, and its upper end is connected to the suction device 20. The duct section 30 is also fixed to the vertical plate 53 of the horizontal sliding section 50, which will be described later.

[0030] As shown in Figure 2, the nozzle section 40 consists of a nozzle section tube 41 made of plastic and formed in a cylindrical shape, with a nozzle 42 having a vertically elongated rectangular cross-section attached to its side surface.

[0031] Two nozzle sections 40 are attached to the duct section 30. One nozzle section has one end of the nozzle section pipe 41 closed, and the other end is connected to the lower end of the duct section 30. The other nozzle section 40 is installed in the central part of the vertically elongated duct section 30, with the duct section 30 connected to both ends of the nozzle section pipe 41.

[0032] Furthermore, the outer diameter of the nozzle pipe 41 is approximately the same as the inner diameter of the cylindrical pipe of the duct section 30, and when the nozzle pipe 41 is inserted into the duct section 30, the nozzle section 40 is connected to the duct section 30.

[0033] The horizontal sliding section 50 includes a guide rail 51, a mounting base 52, a vertical plate 53, and a power source (motor) and ball screw (not shown). The mounting base 52 is mounted on the guide rail 51, and the vertical plate 53 is fixed to the mounting base 52 perpendicular to the mounting base 52. Furthermore, the suction unit 20 is fixed on the mounting base 52, and the duct section 30 is fixed to the vertical plate 53.

[0034] The rotational motion of the power source (motor) is converted into linear motion by a ball screw, and as the mounting base 52 moves along the guide rail 51, the suction machine 20 fixed to the mounting base 52 and the duct section 30 fixed to the vertical plate 53 slide horizontally.

[0035] The frame 60 is used to mount the horizontal sliding section 50 to which the wind power generation section 20 and the duct section 30 are fixed, and is equipped with two legs 61 on the left and right sides and a top plate 62. A horizontal sliding section 50, to which the suction unit 20 and duct section 30 are fixed, is installed on the top plate 62.

[0036] Furthermore, the spacing between the two left and right legs 61, and the height of the top plate 62, are such that they do not interfere with the transport of product sheets in the slitter, even when installed on the line of the slitter.

[0037] (How to use the cutting debris removal device 1) Next, we will explain how to use the cutting debris removal device 1. The procedure for using the cutting debris removal device 1 is as shown in (a) to (f) below.

[0038] (a) Install the cutting debris removal device 1 in the middle of the slitter line, straddling the slitter line at the position where you want to remove the cutting debris. (i) Operate the slitter to cut the sheet material while winding up the product sheet.

[0039] (c) After confirming that all product sheets have been wound up, turn off the power to the slitter. (e) Turn on the power to the cutting debris removal device 1 and operate the suction machine 20 and the horizontal sliding unit 50.

[0040] (e) After confirming that the cutting debris has been sucked up, turn off the power to the cutting debris removal device 1. (c) If necessary, change the installation position of the cutting debris removal device 1 in the slitter line, turn on the power to the cutting debris removal device 1 again, and perform suction of the cutting debris. If necessary, change the position or number of nozzles 40 at that time.

[0041] (Features of the cutting debris removal device 1) In this type of cutting debris removal device 1, the suction force generated by the suction device 20 is used to suck up the cutting debris that is produced when the sheet material is cut in the slitter.

[0042] As air is sucked in from the nozzle section 40 and the nozzle section 40 is slid horizontally, not only the cutting debris from both ends of the sheet material, but also the cutting debris from when the sheet material is cut multiple times vertically in order to wind up multiple product sheets from the sheet material can be sucked in and removed.

[0043] Furthermore, by installing the nozzle section 40 at the lower end of the vertically elongated duct section 30, and also installing another nozzle section 40 near the middle of the duct section 30, it is possible to simultaneously suction and remove not only the cutting debris that has fallen to the ground, but also the cutting debris attached to the various rollers installed on the slitter line.

[0044] Furthermore, it becomes possible to remove not only cutting debris generated when cutting sheet material, but also various types of dust generated during slitter operation. For example, if the sheet material is wound on a paper core, it can also remove paper dust generated when attaching and detaching the paper core.

[0045] [Second Embodiment] Next, based on Figure 3, a second embodiment will be described in which a broom section 70 is provided instead of the air power generation section 20, duct section 30, and nozzle section 40 that are provided as the removal section 10 of the cutting debris removal device 1 in the first embodiment. Figure 3 is an external view showing the schematic shape of the cutting debris removal device in the second embodiment (Figure 3(A) is a front view, Figure 3(B) is a left side view, and Figure 3(C) is a top view).

[0046] Since the cutting debris removal device in the second embodiment is similar to the cutting debris removal device 1 in the first embodiment, the same reference numerals are used for the same components, and their descriptions are omitted. Furthermore, the cutting debris removal device in the second embodiment differs from the cutting debris removal device 1 in the first embodiment only in the method of removing cutting debris (suction versus sweeping), and its usage is the same, so a description of its usage is omitted.

[0047] As shown in Figure 3, the broom section 70 comprises a brush section 71 and a fixing section 72. The brush portion 71 is formed into a brush shape by bundling together plant branches or fibers. The fixing portion 72 holds the brush portion 71 and is also fixed to the vertical plate 53.

[0048] Two broom sections 70 are attached to the vertical plate 53. One of them is attached downwards to the lower end of the vertical plate 53, with the brush section 71 facing downwards so that it can sweep out the cutting debris that has fallen on the slitter contact surface in a horizontal direction.

[0049] The other broom section 70 is attached near the upper and lower center of the vertical plate 53, with the brush section 71 facing in the direction in which the sheet material is conveyed on the slitter line.

[0050] (Features of the cutting debris removal device in the second embodiment) In the cutting debris removal device of the second embodiment, by moving multiple broom sections 70 horizontally, not only cutting debris that has fallen onto the contact surface of the slitter, but also cutting debris attached to various rollers in the slitter line can be swept away simultaneously, thereby efficiently removing cutting debris.

[0051] [Other embodiments] (1) In the above embodiment, a fan-powered suction device 20 is used as the wind power generation unit 20, but a blower or the like may be used as the wind power generation unit 20, and the cutting debris may be sucked up by its suction function.

[0052] (2) In the above embodiment, a suction device 20 with a built-in fan is used as the wind power generating unit 20, thereby utilizing the suction function of the fan. However, a blower 20 that utilizes the blowing function of a fan or the blowing function of a blower or the like may be used to release air from the nozzle unit 40 through the duct unit 30, thereby blowing away and removing the cutting debris.

[0053] (3) In the above embodiment, one nozzle 40 or broom 70 is attached near the center of the cutting debris removal device 1 and one at the bottom. However, there are no restrictions on the number of nozzles 40 or brooms 70 to be attached or their installation positions. The number of nozzles 40 or brooms 70 to be attached may be one or three or more. The installation position may also be any position relative to the horizontal sliding part 50.

[0054] (4) In the first embodiment, the nozzle section 40 has a nozzle 42 with a vertically elongated rectangular cross-section attached to the side surface of the nozzle section tube 41. However, the cross-sectional shape of the nozzle 42 is not limited to this, and nozzles 42 with various cross-sectional shapes, such as an elliptical shape, may be used.

[0055] (5) In the first embodiment, no separate joints are used to connect the nozzle section 40 and the duct section 30, but various joints such as pipe joints may be used to connect the nozzle section 40 and the duct section 30. [Explanation of symbols]
