Description

Sheet cutting device with dry cleaning machine

The invention relates to a sheet cutting device with a dry cleaning machine, which cuts the surface of the cut sheet after cutting the sheet with a specific size.

There are many types of electronic machines that use thin sheets. The method for producing such a thin plate material is a melting method, for example, a sheet having a thickness of 1 mm or less is produced.

As shown in Fig. 7, the sheet material produced by this method is conveyed in the conveyance direction W after the sheet material 100 cut by a predetermined length, and the end portion 101 in the width direction is cut at the cutting line L. Plate 102 of a particular width. In the documents of the present specification and the patent application, the direction in which the sheet is conveyed is referred to as "long direction", and the direction perpendicular to the conveyance direction is "wide direction".

In the case of cutting the sheet material, for example, it is cut along the cutting line L using a mechanical cutter or a laser.

The cut piece 100 is scattered when the cut piece 100 is cut. If the cut piece is kept in a state of being scattered and adhered to the surface of the sheet, the quality of the processed sheet product is lowered. In addition, there is a case where the surface of the cut sheet adheres to the surrounding dust to lower the quality of the sheet.

Therefore, as a prior art in this field, for example, the washing water is sprayed from the washing head to the conveyed plate to remove the cut piece attached to the surface of the plate, and the air is sprayed from the washing head to dry the washing surface. (See Patent Document 1).

[Problems to be solved by the invention]

However, in the apparatus of Patent Document 1, it is necessary to wash the washing water for the plate material, the detergent, and the pure water for washing. Moreover, the use of pure water for washing requires a lot of machines, which not only complicates the construction but also increases initial costs and operating costs. Moreover, energy consumption is also large and environmental protection is not good.

In addition, the plate is supported by the rollers during washing, so in order to avoid the plate bending and the roller to achieve stable support, it is necessary to arrange the spacing between the rollers to be narrow. Moreover, if the size of the sheet is changed, it may be necessary to match the size to increase the roller. Therefore, it is difficult to correspond to thin sheets or sheets of various widths.

In addition, if the sheet is conveyed by the roller at the washing place, the friction or sliding of the roller which is in contact with the surface of the sheet to be conveyed may have a bad influence on the quality of the sheet.

Accordingly, an object of the present invention is to provide a sheet cutting device having a dry cleaning machine capable of removing adhering pieces such as cut pieces attached to a surface without damaging the sheet material in a simplified structure, and even if the sheet width is changed. Can correspond.

[Means for solving problems]

In order to achieve the above object, a sheet cutting device according to the present invention includes a cutting machine that cuts a sheet material, and a conveying machine that is disposed under the cutting machine and conveys the sheet material cut by the cutting machine in a downward flow direction. The conveyor has a dry cleaning machine that can clean the surface of the conveyed sheet. The dry cleaner has an air cleaner that sprays the cleaning air toward the surface of the sheet to peel off the deposit from the sheet and attract the peeled adhesion. The air guide is provided in the conveyance direction W and the upstream side and the downstream side of the air cleaner, and the sheet material can be floated and passed through the position of the air cleaner in a non-contact manner. The "cutting" mentioned in this manual and the scope of the patent application includes the "cutting" and "breaking" of the sheet at a specific position. In addition, the term "attachment" as used in the specification and the scope of the patent application refers to a "cut piece" which is caused by cutting of a sheet material, or dust which is scattered around.

With this configuration, the sheet cut by the cutter can be stably transported to the position of the air cleaner by the air guide in the air floating state. Moreover, since the air guide is stably carried, the air cleaner can be placed close to the sheet. Then, the air is sprayed from the air cleaner to the surface of the sheet which is conveyed downward, so that the adhered matter is peeled off and the peeled deposit is attracted, so that the board which passes through the dry cleaner can achieve a high washing effect. Moreover, even if the width dimension of the sheet varies, stable handling can be achieved by the air guide.

Further, the air cleaner is disposed at a predetermined angle from a direction perpendicular to the sheet conveying direction, and may be disposed to face a specific gap from the sheet conveyed by the conveyor, and face the upper and lower positions.

According to this configuration, it is possible to stably spray the cleaning air from one end of the sheet to the other end to suppress the bending of the sheet, and simultaneously wash the upper and lower sides of the sheet from the cutter to the downstream side in the conveying direction.

Alternatively, the air guide can have an auxiliary plate that allows the plate to float to a position adjacent to the inclined air cleaner.

With this configuration, the sheet material can be conveyed from the air guide to the auxiliary plate in an air floating state and carried in a more stable manner until it approaches the position of the air cleaner.

Further, the air cleaner has an air jet nozzle that ejects air toward the upstream side in the sheet conveying direction, and the air jet nozzle may have an air suction port on the upstream side in the conveying direction.

According to this configuration, the deposit can be blown up by the air ejected from the downstream side to the upstream side in the conveyance direction, and the blown deposit can be sucked and collected in the upstream side in the conveyance direction.

Further, the air cleaner may have a cylindrical spray nozzle that ejects air from a surrounding cylindrical shape and sucks and collects the blown deposit from the center portion.

According to this configuration, the air that is sprayed from the periphery of the injection nozzle can be sucked and collected from the center portion by the air that is sprayed from the periphery of the injection nozzle.

[effect of the invention]
According to the present invention, it is possible to remove deposits such as cut pieces which are generated when the sheet material is cut by a dry cleaning machine. Thereby, it is possible to form a sheet cutting device with a dry cleaning machine which improves the quality of the sheet and is environmentally friendly.

Embodiments of the invention are described below in accordance with the drawings. In the following examples, an example in which the end portions of both sides of the conveyed sheet material are cut and the surface is washed is described. In the two embodiments described below, the same components are denoted by the same reference numerals.

As shown in Fig. 1, the sheet cutting device 1 for a dry cleaning machine according to the first embodiment has a cutting machine 2 on the upstream side in the conveying direction of the sheet material 50, and a dry cleaning machine 10 on the downstream side.

In the cutting machine 2, the conveyance conveyance device 4 is provided above the cutting frame table 3, and the cutting unit 6 is provided above it. The conveyance conveyor 4 is driven by the drive motor 5 to convey the sheet material 50 in the conveyance direction W. The cutting unit 6 cuts both side portions of the sheet material 50 conveyed by the conveyance conveyor 4 . The cutting unit 6 has a mechanical cutter 7 (hereinafter referred to as "cutter 7") that can adjust the position in the vertical direction. The cutting unit 6 is moved in the conveying direction W by the guide portion 40 that extends in the conveying direction W. Further, a cutting table 8 is provided below the cutting unit 6. The center of the cutting table 8 and the center of the cutter 7 are on the same lead line in the width direction. The sheet 50 can be cut along the cutting line L (Fig. 6) by the cutter 7.

The guide unit 40 can move the cutter device 6 in the transport direction W in the return direction by the drive motor 42 provided at one end. Further, the guide portion 40 can be moved in the width direction by cutting the width resizing mechanism 41 on the rack table 3. The width adjustment mechanism 41 is configured to adjust the position of the guide portion 40 in the width direction along the rail 43. Further, the cutting table 8 is also configured to have a width adjustment mechanism 45 to adjust the position along the rail 46. By moving the guide portion 40 and the cutting table 8 in the width direction (the direction perpendicular to the paper surface), the end portion size of the sheet material 50 cut by the cutter device 6 can be changed, and the width dimension of the product sheet 50 can be changed. Further, the other detailed structure regarding the cutter 2 will be omitted.

By the cutter 2, the sheet material 50 conveyed by the conveyance conveyor 4 can be held at a specific position, and both ends of the sheet member 50 can be cut by the cutter 7.

In the dry cleaning machine 10, transport conveyance devices 12 and 13 are provided above the clean rack table 11, and the sheet material 50 conveyed from the conveyance conveyor 4 of the cutter 2 is conveyed in a downward flow direction. The transport conveyor is provided with a plurality of transport belts (refer to FIG. 2) at predetermined intervals in the width direction of the steps 12 and 13, and is divided into an upstream side conveyance conveyor 12 and a downstream conveyance conveyor 13. The upstream side conveyance conveyance device 12 is driven by the drive motor 14, and the downstream flow conveyance conveyance device 13 is driven by the drive motor 15. Then, an air cleaner 16 is provided between the upstream side conveying conveyor 12 and the downstream side conveying conveyor 13.

The air cleaner 16 is configured to wash and wash the adhering matter such as a cut piece attached to the surface of the plate member 50 cut by the cutter 2.

As shown in Fig. 2, the air cleaner 16 in the dry cleaning machine 10 of the first embodiment is disposed at a predetermined angle in a direction perpendicular to the conveyance direction W of the sheet material 50. The specific angle at which the air cleaner 16 is tilted is set to an angle of only a few degrees. By arranging the air cleaner 16 slightly, the sheet material 50 conveyed from the upstream conveyance conveyor 12 can be ejected by the air jet from the one end portion to the other end portion. The deflection of the sheet 50 is suppressed. Details of the air cleaner 16 will be described later.

Further, air guides 17, 18 are provided between the air cleaner 16 disposed obliquely and the conveyance conveyors 12, 13. In the air guides 17, 18 of the first embodiment, since the air cleaner 16 is disposed obliquely, the gap between the air guides 16 and the upstream conveying conveyance device 12 and the downstream conveying conveyor 13 is on the side in the width direction. The air guides 17, 18 are disposed in this expanded portion. The air guides 17 and 18 are of the same structure.

On the other hand, in the dry cleaning machine 20 of the second embodiment shown in Fig. 3, the arrangement angle of the air cleaner 16 is set to be closer to the angle perpendicular to the conveyance direction W. Then, between the air cleaner 16 and the upstream side conveying conveyor 12 and the downstream conveying conveyance device 13, air guides 21 and 22 extending over the entire width direction are provided. The air guides 21 and 22 have the same structure.

Further, in this embodiment, the auxiliary plates 23, 24 are provided in the gap portion between the air guides 21, 22 which are produced by obliquely arranging the air cleaner 16. Further, even in the embodiment shown in Fig. 2, an auxiliary plate may be provided between the air cleaner 16 and the air guides 17, 18 as indicated by two dotted lines.

As shown in Fig. 4, the air guides 21, 22 have a guide body 25 and a plurality of air blowout ports 26. The upper surface of the guide body 25 is formed into a flat box shape, and the plurality of air blowing outlets 26 are disposed on the upper surface of the guide body 25. The air guides 21 and 22 blow the floating air 28 supplied from the lower air supply port 27 from the air blowing port 26.

Then, the floating air 28 blown by the air blowing port 26 forms an air layer with the upper plate and the conveyed plate 50, and the air layer supports the plate 50 in a non-contact state. Further, the air guides 17, 18 have the same configuration, and thus the description thereof will be omitted. Further, the figure is an exaggeration indicating that the sheet 50 is in a floating state.

Next, the air cleaner 16 and the air guides 21 and 22 in the dry cleaning machine 20 shown in Fig. 3 will be described in detail based on Fig. 5. In this embodiment, an air cleaner 16 is provided at an upper and lower position of the sheet 50 to be conveyed, and the upper and lower surfaces of the conveyed sheet 50 can be simultaneously washed. Since the air cleaner 16 disposed at the upper and lower positions has the same configuration, the upper air cleaner 16 will be mainly described.

The air cleaner 16 is disposed to have a specific gap S between the surface of the sheet 50 to be conveyed. Further, the air cleaner 16 is provided with a cleaning air ejection port 30 and a suction port 31. The cleaning air injection port 30 is disposed on the downstream side in the conveyance direction, and the suction port 31 is disposed on the upstream side in the conveyance direction. The cleaned air 33 is ejected from the washing air ejection port 30 in the upward flow direction, and is sucked by the suction port 31. The cleaned air 33 is supplied or discharged from the clean air duct port 32. The cleaning air injection port 30 and the suction port 31 are continuously provided in the longitudinal direction of the air cleaner 16 (that is, in the width direction of the plate member 50), and are sprayed from the cleaning air injection port 30 toward the entire width direction of the plate member 50. The air 33 is attracted to the suction port 31.

Next, the air guides 21 and 22 are provided between the air cleaner 16 and the upstream side conveyance conveyor 12 and the downstream conveyance conveyor 13. The air guides 21 and 22 supply the floating air 28 from the lower air supply port 27, and the floating air 28 is blown upward from the air blowing port 26 provided on the upper surface. The air guides 21, 22 are formed in a planar shape, and are supplied between the plate and the plate 50 by the floating air 28 blown from the air outlet 26, by which the floating air 28 is between the plate 50 and the plate 50. The air layer is formed to support the sheet 50 in a non-contact state.

Further, in this embodiment, the auxiliary plates 23, 24 are provided from the air guides 21, 22 toward the air cleaner 16. The auxiliary plates 23, 24 are provided in the gap portion between the air guides 21, 22 and the air cleaner 16. By the auxiliary plates 23, 24, the floating air 28 blown by the air guides 21, 22 also flows between the plate members 50 carried in the portions of the auxiliary plates 23, 24, and on the auxiliary plates 23, 24 An air layer is also formed between the upper surface and the sheet 50. The auxiliary plates 23, 24 can support the sheet 50 in a floating state to a position close to the air cleaner 16.

As described above, in the dry cleaning machine 20 of the second embodiment, the air guides 21 and 22 and the auxiliary plates 23 and 24 are provided upstream and downstream of the air cleaner 16, so that the transport device 12 and the downstream conveyance are transported on the upstream side. Between the conveying device 13 and the air cleaner 16, the sheet member 50 can be supported in an air-floating state by the air guides 21, 22 and the auxiliary plates 23, 24.

Therefore, according to the dry cleaning machine 20 of the second embodiment, the sheet material 50 conveyed from the upstream side conveying and conveying device 12 can be non-contacted by the wide surface of the upper surface of the air guiding member 21 and the upper surface of the auxiliary plate 23. The state is supported, and the plate 50 is passed through the air cleaner 16 in a non-contact state, and the plate 50 is supported in a non-contact state by the upper surface of the auxiliary plate 24 and the upper surface of the air guide 22 on the downstream side. . Therefore, the sheet 50 that has passed through the air cleaner 16 can be supported in a stable state, and the deposits such as cut pieces attached to the surface of the sheet 50 can be peeled off by the washing air 33 sprayed from the cleaning air jet port 30. It is sucked and collected from the suction port 31, and can be washed with air having a high washing effect.

In addition, since the air cleaner 16 is disposed obliquely, when the cleaning air 33 is ejected from the cleaning air ejection port 30 and is sucked from the suction port 31, the one end portion in the width direction is toward the other end portion. When the sheet 50 is washed, the sheet 50 can be washed by the sheet 50 without being deflected by spraying and sucking the cleaning air 33.

6A and 6B are views showing a method of cleaning the surface of the sheet material 50 by the air cleaner 16. Fig. 6A is a washing method shown in Fig. 5, in which the washing air injection port 30 is provided from the flow side below the conveying direction W, and the washing air 33 is sprayed toward the surface of the plate 50 at an acute angle, and in the conveying direction W. The suction port 31 provided on the upstream side separates the suction air 33 and the deposits reflected on the surface of the plate material 50.

In Fig. 6B, the cleaning air 33 is sprayed from the cylindrical injection port 34 in a direction perpendicular to the surface of the plate member 50, and is attracted from the suction port 35 provided at the center portion of the injection port 34 to be reflected on the surface of the plate member 50. Wash the air 33 and the attached matter.

The above is only one example of the method of cleaning the surface of the sheet material 50 by air. Any structure may be used as long as it can spray the cleaning air 33 to the surface of the sheet material 50, peel off the deposit, and attract the deposit.

As described above, according to the sheet cutting device 1 having the dry cleaning machine, the sheet material 50 cut by the cutter 2 can be conveyed to the dry cleaning machines 10 and 20 by the conveyance conveyor 4, and in the dry cleaning machine 10, 20 Among them, the plate member 50 can be passed through the air cleaner 16 in an air floating state by the air guides 21 and 22 to perform stable air washing.

Further, the air cleaner 16 can be placed close to the sheet 50, and the sheet 50 can be conveyed in a non-contact manner while the cleaning air 33 is sprayed toward the surface of the sheet 50 to peel off and attract the deposit on the surface. For the plate 50 passing through the dry cleaning machines 10, 20, it is possible to stably perform the cleaning of the high effect.

Further, since the air cleaner 16 and the air guides 21 and 22 can use the common air, the operating cost can be reduced, and the dry cleaning machines 10 and 20 having good environmental protection can be constructed by using the initial air cost and energy consumption.

Further, even if the width dimension of the plate member 50 is varied, since the air guides 21, 22 supply the floating air 28 from the entire width direction, stable conveyance can be achieved by washing from the entire width direction of the air cleaner 16 The clean air 33 can wash the entire surface of the sheet 50.

Further, in the second embodiment, since the auxiliary plates 23 and 24 are provided in the air cleaner 16 and the air guides 21 and 22, the floating air 28 ejected from the air guides 21 and 22 is on the auxiliary plate 23, There is also a flow between the sheet 24 and the sheet 50, so that the sheet 50 can be brought close to the position of the air cleaner 16 in an air-floating state for more stable air washing.

Further, in the above-described embodiment, an example has been described in which the air cleaner 16 is used to simultaneously clean the upper and lower surfaces of the sheet material 50. However, it is also possible to install only the air cleaner on the upper side and wash the sheet with a large amount of deposits. Above 50.

Further, in the above-described embodiment, an example in which the cutting line L is formed first and then cut along the cutting line L has been described, but the cutting line L may not be cut and cut.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit and scope of the invention.
