Description

Sheet processing device

Technical Field

The utility model relates to a sheet material processing device for processing long strip sheets.

Background Art

A sheet material processing apparatus for conveying and processing a long sheet material is known.

Patent document 1 discloses an electrode manufacturing device having a gripper for gripping a sheet-shaped electrode material and conveying it to a cutting position for cutting the electrode material. FIG12 is a top view schematically showing the structure of the electrode manufacturing device 200 described in Patent document 1. FIG13 is a side view schematically showing the structure of the electrode manufacturing device 200 described in Patent document 1.

The electrode manufacturing device 200 includes a gripper 210, a first suction conveyor 220, a second suction conveyor 230, a front die 240, and a rear die 250. The gripper 210 moves upward while gripping a sheet of electrode material 260, thereby conveying the electrode material 260 to the front die 240 while lifting it from the first suction conveyor 220. The front die 240 and the rear die 250 cut the long strip of electrode material 260, respectively. When cutting the electrode material 260, the electrode material 260 is sucked and held by the first suction conveyor 220. The cut electrode material 260 is conveyed by the second suction conveyor 230 to a position further forward than the front die 240.

Patent Document 1: Japanese Patent Application Publication No. 2012-227123

Here, there is a case where the sheet-like electrode material 260 is warped in at least one direction of the width direction and the length direction. In the electrode manufacturing device 200 described in Patent Document 1, the gripper 210 grasps the electrode material 260 and transports it in mid-air to the front end mold 240 for cutting, but as shown in Figures 12 and 13, the front part of the electrode material 260 is not grasped. Therefore, in the case where the electrode material 260 is warped, it will be transported to the front end mold 240 while maintaining the warped state, and the front end mold 240 will cut the electrode material 260 in the warped state. Therefore, due to the warping, the electrode material 260 may not be properly cut. This is also the case when the processing of the electrode material 260 is a processing other than cutting, and in addition, the sheet material to be processed is a sheet material other than the electrode material 260.

DETAILED DESCRIPTION

Hereinafter, embodiments of the present invention will be shown to specifically describe the features of the present invention.

Fig. 1 is a side view schematically showing the overall structure of a sheet processing apparatus 100 in one embodiment. Fig. 2 is a perspective view schematically showing the structure of a conveying unit 10 described later in the sheet processing apparatus 100 in one embodiment. Fig. 3 is a perspective view schematically showing the structure of the conveying unit 10 in the sheet processing apparatus 100 when viewed from the side of an adsorption surface 12a described later.

The sheet processing apparatus 100 in one embodiment includes a conveying unit 10 , a suction stage 21 , and a processing unit 22 .

The conveying unit 10 includes a gripping unit 11 for gripping the long sheet 1 by sandwiching the long sheet 1 and a suction unit 12 for sucking the sheet 1 by suction.

For example, as shown in FIG1 , a long strip of sheet 1 is unwound from an unwinding roller 2 and supplied to a position where a conveying unit 10 is provided. The width of the sheet 1 is, for example, greater than 50 mm and less than 200 mm, and the thickness is, for example, greater than 0.05 mm and less than 0.1 mm. The sheet 1 is made of any material, for example, at least one of metal, resin, and ceramic. The sheet 1 may also be a sheet in which a plurality of materials with different shrinkage rates are overlapped and arranged in a direction orthogonal to the surface of the sheet 1, or a sheet that continues to maintain a certain deformation when an external force is released. For example, the sheet 1 may also be any one of a ceramic raw sheet, a sheet consisting of a two-layer structure of ceramic and resin, a sheet consisting of a two-layer structure of metal foil and resin, a sheet consisting of a two-layer structure of metal foil and ceramic, a sheet consisting of a two-layer structure of metal foil and an electrode active material layer, and a printed dried sheet.

Warping may occur in the sheet 1 having a structure in which a plurality of materials having different shrinkage ratios are stacked and arranged in a direction perpendicular to the surface of the sheet 1 as described above. Fig. 4(a) to Fig. 4(c) are perspective views schematically showing the shape of the sheet 1 in which warping occurs.

FIG. 4 (a) is a diagram showing an example of the shape of the sheet 1 in a state where warping occurs in a bulging manner toward the upper side. More specifically, the central portion of the sheet 1 in the width direction is warped in a bulging manner toward the upper side. FIG. 4 (b) is a diagram showing an example of the shape of the sheet 1 in a state where warping occurs in a bulging manner toward the lower side. More specifically, the central portion of the sheet 1 in the width direction is warped in a bulging manner toward the lower side. It should be noted that the upper side and the lower side are based on a state where the sheet 1 without warping is placed on a horizontal plane. FIG. 4 (c) is a diagram showing an example of the shape of the sheet 1 in a state where warping occurs in the longitudinal direction of the sheet 1.

The sheet processing device 100 in one embodiment can be particularly preferably used for a sheet 1 that is warped. As shown in FIG. 4(a) to FIG. 4(c), the sheet 1 that is warped is warped in at least one of the length direction and the width direction of the sheet 1. According to the sheet processing device 100 in one embodiment, as described later, regardless of whether the sheet 1 is warped in a manner of bulging upward, warping in a manner of bulging downward, warping in the length direction of the sheet 1, or warping in the width direction of the sheet 1, it can be processed in a state where the warping is suppressed.

The gripping portion 11 of the conveying portion 10 includes a first flat portion 11a and a second flat portion 11b disposed at positions opposite to each other in a direction perpendicular to the surface of the sheet 1, and the sheet 1 is gripped by clamping the first flat portion 11a and the second flat portion 11b. An elastic body may also be provided at the portion where the gripping portion 11 contacts the sheet 1, specifically, at the portion where the first flat portion 11a contacts the sheet 1 and at the portion where the second flat portion 11b contacts the sheet 1. By adopting a configuration in which an elastic body is provided at the portion where the gripping portion 11 contacts the sheet 1, the frictional resistance with the sheet 1 can be increased, and the sheet 1 can be gripped more reliably. The elastic body is, for example, rubber or resin.

In addition, instead of providing an elastic body at the portion where the gripping portion 11 and the sheet 1 are in contact, an anti-slip agent may be applied, or a concavo-convex surface may be provided. The anti-slip agent may be a known anti-slip agent. By adopting a configuration in which an anti-slip agent is applied to the portion where the gripping portion 11 and the sheet 1 are in contact, the sheet 1 can be gripped more reliably. In addition, by adopting a configuration in which a concavo-convex surface is provided at the portion where the gripping portion 11 and the sheet 1 are in contact, the sheet 1 can be gripped more reliably.

The suction portion 12 of the conveying portion 10 has a suction surface 12a for sucking the sheet 1. As shown in FIG3 , a plurality of suction holes 12b are provided on the suction surface 12a. The shape, size and number of the suction holes 12b are arbitrary. For example, the suction holes 12b are circular in shape, and the suction holes 12b provided at positions corresponding to the edge of the sheet 1 in the suction surface 12a may also be groove-shaped. By making the suction holes 12b provided at positions corresponding to the edge of the sheet 1 be groove-shaped, the sheet 1 can be sucked more reliably.

The suction hole 12b is connected to a suction device (not shown) to generate suction force on the suction surface 12a. However, the structure for generating suction force is not limited to the above structure, and for example, a vacuum pad may be embedded in the suction surface 12a to generate suction force.

It should be noted that the suction surface 12 a may have holes or depressions depending on the shape of the destination to which the sheet 1 is to be transported.

The size of the suction surface 12a in the width direction is preferably larger than the size of the sheet 1 in the width direction. The width direction of the suction surface 12a and the width direction of the sheet 1 are the same direction. By making the size of the suction surface 12a in the width direction larger than the size of the sheet 1 in the width direction, the sheet 1 can be more reliably suctioned by the suction surface 12a, and the sheet 1 can be conveyed in a state where warping is effectively suppressed. However, the size of the suction surface 12a in the width direction may be smaller than the size of the sheet 1 in the width direction.

1 , the suction unit 12 is configured to suck the sheet 1 from above. That is, the suction surface 12a of the suction unit 12 is located above the sheet 1. However, as described later, the suction unit 12 may be configured to suck the sheet 1 from below.

The conveying section 10 is configured to convey the sheet 1 to the suction workbench 21 in a state where the gripping section 11 grips the sheet 1 and the suction section 12 adsorbs the sheet 1. When the sheet 1 is conveyed by the conveying section 10, the top end of the sheet 1 in the conveying direction preferably does not protrude from the adsorption surface 12a. By preventing the top end of the sheet 1 in the conveying direction from protruding from the adsorption surface 12a, the sheet 1 can be more reliably adsorbed by the adsorption surface 12a when the sheet 1 is conveyed, and the sheet 1 can be conveyed in a state where warping is effectively suppressed. However, when the sheet 1 is conveyed, the top end of the sheet 1 in the conveying direction may protrude from the adsorption surface 12a. Even in this case, in order to more reliably adsorb the sheet 1, it is preferred that the top end of the sheet 1 protrudes from the adsorption surface 12a as little as possible.

In the present embodiment, the suction part 12 is provided integrally with the first flat plate part 11a of the gripping part 11. Specifically, the second flat plate part 11b and the portion of the first flat plate part 11a that is opposite to the second flat plate part 11b constitute the gripping part 11. In addition, the suction part 12 is provided in the portion of the first flat plate part 11a other than the portion that is opposite to the second flat plate part 11b. However, the suction part 12 may be provided separately from the first flat plate part 11a that constitutes the gripping part 11.

1 , in this embodiment, the suction portion 12 is located at the front side of the conveying direction of the sheet 1 relative to the gripping portion 11. That is, the suction portion 12 is located at the front side of the conveying direction of the sheet 1, and the gripping portion 11 is located at the rear side.

However, as shown in FIG5 , the gripping portion 11 may be located at the front side of the conveying direction of the sheet 1 relative to the suction portion 12. However, in this case, when the sheet 1 is conveyed to the suction table 21 by the conveying portion 10, the conveying portion 10 needs to be raised until the second flat plate portion 11b is at a higher position than the suction table 21. Therefore, from the perspective that the amount of raising the conveying portion 10 is small, it is preferred that the suction portion 12 is located at the front side of the conveying direction of the sheet 1 relative to the gripping portion 11.

In addition, as shown in FIG. 6(a) and FIG. 6(b), the gripping portion 11 and the suction portion 12 may be arranged in the width direction of the sheet 1. FIG. 6(a) is a top view schematically showing the structure of the conveying portion 10 in the case where the gripping portion 11 and the suction portion 12 are arranged in the width direction of the sheet 1, and FIG. 6(b) is a diagram schematically showing the structure of the conveying portion 10 shown in FIG. 6(a) when viewed in the direction of arrow Y1. According to the structure in which the gripping portion 11 and the suction portion 12 are arranged in the width direction of the sheet 1, the configuration space of the conveying portion 10 in the length direction of the sheet 1 can be reduced.

Furthermore, as shown in FIG. 7 (a) and FIG. 7 (b), two conveying sections 10 may be arranged in the width direction of the sheet 1. FIG. 7 (a) is a top view schematically showing a structure in which two conveying sections 10 are arranged in the width direction of the sheet, and FIG. 7 (b) is a diagram schematically showing a structure when the conveying section 10 shown in FIG. 7 (a) is observed in the direction of arrow Y2. According to the configuration example shown in FIG. 7, two gripping sections 11 and two suction sections 12 are arranged in the width direction of the sheet 1, respectively. In the configuration example shown in FIG. 7, the suction section 12 is located at the front side of the conveying direction of the sheet 1 more than the gripping section 11, but may be located at the rear side of the conveying direction of the sheet 1 more than the gripping section 11, or may be arranged in the width direction of the sheet 1 with the gripping section 11.

The conveying unit 10 is configured to be movable in the length direction of the long sheet 1 and in a direction perpendicular to the surface of the sheet 1. As described later, when conveying the sheet 1 to the suction workbench 21, the conveying unit 10 moves in the length direction of the sheet 1 after moving in a direction perpendicular to the surface of the sheet 1.

The suction table 21 sucks the sheet 1 by suction. For example, a plurality of suction holes are provided in the suction table 21, and the sheet 1 is sucked by suction through the suction holes. The suction table 21 may be configured as a part of the processing unit 22.

The processing unit 22 processes the sheet 1 in the state of being sucked by the suction table 21. The processing performed by the processing unit 22 on the sheet 1 is, for example, at least one of cutting the sheet 1, printing on the sheet 1, ejecting a liquid or other ejection material on the sheet 1, heat treating the sheet 1, measuring the sheet 1, inspecting the sheet 1, laser processing the sheet 1, assembling the sheet 1, laminating the sheet 1, and conveying the sheet 1. However, the processing performed by the processing unit 22 on the sheet 1 is not limited to the above-mentioned processing.

Hereinafter, the operation of the sheet material processing device 100 in the present embodiment will be described with reference to Fig. 8 and Fig. 9. Herein, the sheet material processing device 100 will be described as being further provided with a receiving table 30. The receiving table 30 is provided in front of the processing unit 22 in the conveying direction of the sheet material 1. The receiving table 30 is configured to be able to adsorb the sheet material 1 placed thereon by sucking. In addition, the processing unit 22 will be described as cutting the sheet material 1.

FIG8(a) is a diagram showing the state of the sheet piece 1s cut by the processing section 22 after being taken out from the processing section 22. Although omitted in FIG8(a), the cut sheet piece 1s is taken out from the processing section 22 by being adsorbed by, for example, an adsorption head. When the cut sheet piece 1s is taken out from the processing section 22, the long sheet 1 is gripped by the gripping portion 11 of the conveying section 10, and is adsorbed by the suction portion 12 and adsorbed by the receiving table 30. Here, at least the portion of the long sheet 1 gripped by the gripping portion 11 extends in the horizontal direction. As shown in FIG8(a), the receiving table 30 is arranged between the second flat plate portion 11b of the conveying section 10 and the suction workbench 21 in the conveying direction of the sheet 1.

After releasing the suction of the receiving table 30 from the state shown in FIG8 (a), the conveying unit 10 is moved in a direction perpendicular to the surface of the sheet 1 and then in the longitudinal direction of the sheet 1, thereby conveying the sheet 1 to the suction table 21 (FIG8 (b)). Here, the conveying unit 10 is moved in a horizontal direction toward the suction table 21 after being moved in an upward direction, thereby conveying the sheet 1 to the suction table 21. When the conveying unit 10 conveys the sheet 1 to the suction table 21, by moving the conveying unit 1 in a direction perpendicular to the surface of the sheet 1 and then in the longitudinal direction of the sheet 1, it is possible to prevent the sheet 1 from contacting the suction table 21.

When conveying the sheet 1 to the suction worktable 21, the conveying unit 10 conveys the sheet 1 in a state where the gripping unit 11 grips the sheet 1 and the suction unit 12 sucks the sheet 1. By conveying the sheet 1 in a state where the gripping unit 11 grips the sheet 1 and the suction unit 12 sucks the sheet 1, even if the sheet 1 is warped, the sheet 1 can be conveyed in a state where the warping is suppressed.

Here, when the conveying unit 10 conveys the sheet 1 to the suction worktable 21, it may also move in the length direction of the sheet 1 while moving in the direction perpendicular to the surface of the sheet 1. For example, the conveying unit 10 may simultaneously start moving in the direction perpendicular to the surface of the sheet 1 and moving in the length direction of the sheet 1, or may start moving in the length direction of the sheet 1 while moving in the direction perpendicular to the surface of the sheet 1. By moving the conveying unit 10 in the length direction of the sheet 1 while moving in the direction perpendicular to the surface of the sheet 1, the sheet 1 can be conveyed to the suction worktable 21 more quickly.

When the conveying unit 10 conveys the sheet 1 to the suction workbench 21, tension is applied to the sheet 1 in the length direction. The method of applying tension to the sheet 1 can be carried out by any method. For example, tension can be continuously applied in the length direction of the sheet 1 by moving the tension control roller 40. It should be noted that in the process shown in (a) of Figure 8 to (c) of Figure 9, it is preferred that tension is continuously applied in the length direction of the sheet 1.

Next, the conveying unit 10 is moved toward the suction table 21, thereby placing the sheet 1 on the suction table 21 ((c) in FIG. 8 ). Here, the conveying unit 10 is moved downward, thereby placing the sheet 1 on the suction table 21. The suction table 21 absorbs the placed sheet 1 by suction. In addition, the receiving table 30 also absorbs the sheet 1 by suction. At this time, the second flat plate portion 11b of the conveying unit 10 is located outside the processing unit 22.

When the conveying section 10 conveys the sheet 1 to the suction table 21, the suction section 12 releases the suction of the sheet 1 at least after the suction table 21 starts to suck the sheet 1. Specifically, the suction section 12 releases the suction at the same time as the suction table 21 starts to suck or at a time slightly later than the start of suction. Therefore, until the sheet 1 adsorbed by the suction section 12 of the conveying section 10 is adsorbed by the suction table 21, the sheet 1 is attracted by at least one of the suction section 12 and the suction table 21. Thus, the positional deviation of the sheet 1 when it is placed on the suction table 21 can be suppressed.

Next, the gripping portion 11 of the conveying portion 10 releases the gripping of the sheet 1 ( FIG. 9( a ) ). In this state, the sheet 1 is sucked and adsorbed by the suction stage 21 and the receiving stage 30 .

In this way, by causing the suction section 12 to suck the sheet 1 from above and placing the sheet 1 on the suction stage 21 , the processing section 22 can process the sheet 1 from the upper surface.

Next, the conveyor 10 is moved in the longitudinal direction of the sheet 1 so that the conveyor 10 goes outside the processing unit 22 and returns to the position before the movement ( FIG. 9( b ) ). Here, the conveyor 10 is moved in the horizontal direction away from the processing unit 22 .

Next, the gripping section 11 of the conveying section 10 grips the sheet 1, and then the suction section 12 sucks the sheet 1 to adsorb it (Fig. 9(c)). The processing section 22 performs a process of cutting the sheet 1.

Thereafter, the steps described using FIG. 8( a ) to FIG. 9( c ) are repeated.

Thus, according to the sheet processing device 100 in one embodiment, the conveying section 10 conveys the sheet 1 to the suction table 21 in a state where the gripping section 11 grips the sheet 1 and the suction section 12 sucks the sheet 1, and the processing section 22 processes the sheet 1 in a state where the suction table 21 sucks the sheet 1, so that even if the sheet 1 is warped, the warping can be suppressed. That is, even if the sheet 1 is warped, the gripping section 11 and the suction section 12 are located close to each other in the conveying section 10, so that the suction section 12 can suck the sheet 1 in a state where the warping is corrected to some extent by gripping the sheet 11, so that the sheet 1 can be stably sucked. The conveying section 10 conveys the sheet 1 to the suction table 21 in a state where the sheet 1 is stretched and the warping is suppressed, and the suction table 21 sucks the conveyed sheet 1 in a state where the warping is suppressed. Therefore, the processing section 22 can process the sheet 1 in a state where the warping is suppressed.

It should be noted that, since the conveying section 10 includes the suction section 12, it is possible to convey the sheet 1 only by the suction section 12 without using the gripping section 11. However, in the case where the sheet 1 is warped, in the case where tension is applied to the sheet 1, or in the case where the sheet 1 is thin and easily damaged, it is difficult to convey the sheet 1 only by suction. According to the sheet processing device 100 in this embodiment, even in such a case, the sheet 1 can be stably conveyed by gripping the sheet 1 with the gripping section 11.

Here, the conveying direction of the sheet 1 is not limited to the horizontal direction. For example, the conveying direction of the sheet 1 may be oblique as shown in FIG. 10( a ) or vertical as shown in FIG. 10( b ).

In addition, in the configuration shown in FIG. 1 , the first flat plate portion 11a is located above the sheet 1 and the second flat plate portion 11b is located below the sheet 1, but as shown in FIG. 11 , the second flat plate portion 11b may be located above the sheet 1 and the first flat plate portion 11a may be located below the sheet 1. In the configuration shown in FIG. 11 , the suction surface 12a of the suction portion 12 is located below the sheet 1. In addition, the suction table 21 suctions the sheet 1 from above for suction.

<Modification>

In the sheet processing apparatus 100 of the above-mentioned embodiment, depending on the amount of warping when the sheet 1 is warped, the first flat plate portion 11a and the second flat plate portion 11b of the conveying unit 10 may interfere with the sheet 1 when moving in the longitudinal direction of the sheet 1. For example, when the conveying unit 10 moves to the outside of the processing unit 22 and returns to the position before the movement (FIG. 9(b)), at least one of the first flat plate portion 11a and the second flat plate portion 11b may contact the warped sheet 1. Therefore, the amount of warping when the sheet 1 is warped may be detected, and based on the detected amount of warping, the conveying unit 10 may be moved in the longitudinal direction of the sheet 1 after being moved away from the sheet 1 in a direction perpendicular to the surface of the sheet 1. In the example shown in FIG. 9(b), for example, when the amount of warping of the sheet is large, the conveying unit 10 may be moved in the longitudinal direction of the sheet 1 after at least one of further moving the first flat plate portion 11a upward and further moving the second flat plate portion 11b downward is performed.

In this case, the sheet processing device 100 may also include a warping amount detection sensor for detecting the warping amount when the sheet 1 is warped. The warping amount detection sensor is, for example, a laser sensor that transmits and receives laser light or an ultrasonic sensor that transmits and receives ultrasonic waves. According to such a configuration, even when the warping amount of the sheet 1 is large, it is possible to prevent the conveying unit 10 from contacting the sheet 1 when moving in the longitudinal direction of the sheet 1.

The present invention is not limited to the above-described embodiment, and various applications and modifications can be made within the scope of the present invention.

The sheet material processing apparatus in the present application is as follows.

<1>. A sheet material processing device, characterized in that it comprises:

The conveying part includes a gripping part and a suction part, wherein the gripping part grips the long strip of sheet material by clamping the sheet material, and the suction part absorbs the sheet material by suction;

a suction workbench for adsorbing the sheet by suction; and
