[0018] Hereinafter, specific embodiments to which this disclosure is applied will be described in detail with reference to the accompanying drawings. However, this disclosure is not limited to the following embodiments. In addition, for clarity, the following description and drawings have been appropriately simplified.

[0019] <Implementation Method 1>

[0020] First, the structure of the sheet member separation device (hereinafter, sometimes simply referred to as the separation device) of this embodiment will be described. Figure 1 (a) to Figure 1 (d) is a diagram illustrating the separation of the sheet-like member in the separation apparatus of this embodiment. Here, for clarity, a three-dimensional (XYZ) coordinate system will be used in the following description.

[0021] The separation device 1 in this embodiment is, for example, as follows: Figure 1 (a) to Figure 1As shown in (d), it is suitable for stacking a sheet member 10, which serves as an electrode or separator, onto a stacked member 11, which serves as an electrode or separator. Furthermore, in the following description, the cut sheet member is sometimes labeled with the reference numeral 10a, and the subsequent sheet member relative to the cut sheet member 10a is sometimes labeled with the reference numeral 10b to distinguish them.

[0022] Separation device 1, for example, Figure 1 As shown in (a), the device includes an anvil roller 2, a cutting roller 3, a transfer roller 4, and a conveying device 5. The anvil roller 2 is similar to a typical anvil roller, for example, it includes a roller section 2a. The roller section 2a is circular when viewed from the Y-axis direction and extends along the Y-axis direction. A plurality of through holes 2b are formed on the circumferential surface of the roller section 2a.

[0023] The length of the roller portion 2a in the Y-axis direction is longer than the width of the sheet member 10 in the Y-axis direction. Furthermore, the perimeter of the roller portion 2a is approximately equal to the length of the sheet member being cut, as described later. The anvil roller 2 is configured such that a pump or the like is connected to a connecting portion 2c formed inside the anvil roller 2 and communicating with the through hole 2b, allowing air to be drawn from the through hole 2b. Additionally, the anvil roller 2 is connected to a drive device and can rotate counterclockwise when viewed from the Y-axis+ side.

[0024] For example, such as Figure 1 As shown in (a), the cutting roller 3 is positioned relative to the anvil roller 2 on the Z-axis+ side. The cutting roller 3, like a typical cutting roller, includes a roller portion 3a and a cutting blade 3b. The roller portion 3a is circular when viewed from the Y-axis direction and extends along the Y-axis. The cutting blade 3b protrudes radially outward from the roller portion 3a and extends along the Y-axis. The length of the roller portion 3a and the cutting blade 3b in the Y-axis direction is longer than the width of the sheet member 10 in the Y-axis direction. The cutting roller 3 is connected to a drive device and can rotate clockwise when viewed from the Y-axis+ side.

[0025] For example, such as Figure 1 As shown in (a), the transfer roller 4 is positioned on the X-axis+ side relative to the anvil roller 2. The transfer roller 4 has a roller portion 4a with a structure substantially the same as that of the roller portion 2a of the anvil roller 2. The roller portion 4a is circular when viewed from the Y-axis direction and extends along the Y-axis direction. The length of the roller portion 4a in the Y-axis direction is longer than the width dimension of the sheet member 10 in the Y-axis direction. The roller portion 4a has a first region 4b and a second region 4c. The first region 4b is the region where air is ejected radially outward from the roller portion 4a. Therefore, a plurality of first through holes are formed in the first region 4b.

[0026] The first region 4b is configured, for example, to have a pump or the like connected to a first connecting portion formed inside the roller portion 4a and communicating with the first through hole, allowing air to be ejected from the first through hole. Figure 1 (a) to Figure 1As shown in (d), the second region 4c is a region capable of switching between ejecting air towards the radially outer side of the roller 4a and drawing air towards the radially inner side of the roller 4a. Therefore, a plurality of second through holes are formed in the second region 4c.

[0027] At this time, for example, Figure 1 As shown in (a), the second region 4c may include a first portion 4d and a second portion 4e. The first portion 4d is the portion capable of adsorbing the front end of the subsequent sheet member 10b relative to the cut sheet member 10a, as detailed later. The second portion 4e is the portion capable of adsorbing the rear end of the cut sheet member 10a, and is disposed on the rotational direction side of the anvil roller 2 relative to the first portion 4d, as detailed later.

[0028] The second through holes in both the first part 4d and the second part 4e can be connected to a pump, for example, via a mechanical valve capable of switching the air intake path and the air supply path according to the rotation angle of the roller 4a, and a second connecting portion formed inside the roller 4a and communicating with the second through hole. Thus, the second region 4c is configured to switch the air intake and air ejection between the first part 4d and the second part 4e respectively, depending on the rotation angle of the roller 4a. The transfer roller 4 is connected to the drive device and can rotate clockwise when viewed from the Y-axis+ side.

[0029] The conveying device 5 can be, for example, a moving-magnet linear motor. The conveying device 5 can be, for example, a moving-magnet linear motor. Figure 1 As shown in (a), a conveying unit 5a is included. The conveying unit 5a is arranged at predetermined intervals in the X-axis direction and has a mounting surface for placing the stacked members 11. The conveying unit 5a can be moved towards the X-axis+ side by a linear motor. At this time, the conveying unit 5a can be accelerated by the linear motor at a preset acceleration.

[0030] Next, the process of separating the sheet member 10 using the separation device 1 of this embodiment will be described. Here, in the following description, we will explain the process of separating and conveying the sheet member 10a to be cut relative to the subsequent sheet member 10b, even before the sheet member 10a has been cut. Here, air continues to be drawn from the through hole 2b of the anvil roller 2, and air continues to be ejected from the first through hole of the first region 4b of the transfer roller 4. Furthermore, the anvil roller 2 continues to rotate. Additionally, the sheet member 10 is conveyed towards the X-axis + side.

[0031] In this state, firstly, as Figure 1As shown in (a), with the anvil roller 2 adsorbing and winding the sheet member 10, the sheet member 10 is conveyed between the anvil roller 2 and the cutting roller 3. Simultaneously, as the transfer roller 4 rotates and the front end of the sheet member 10 is positioned near the end of the anvil roller 2 on the X-axis+ side (i.e., at the 9 o'clock position when viewed from the Y-axis+ side), the first portion 4d of the second region 4c of the transfer roller 4 is positioned on the X-axis- side, and the first portion 4d and the second portion 4e of the second region 4c of the transfer roller 4 are switched from an air ejection state to an air attraction state. At this time, the attraction force of the first portion 4d of the second region 4c of the transfer roller 4 on the front end of the sheet member 10 is set to be stronger than the attraction force of the anvil roller 2 on the front end of the sheet member 10. Therefore, the front end of the sheet member 10 is adsorbed onto the first portion 4d of the second region 4c of the transfer roller 4 and transferred from the anvil roller 2 to the transfer roller 4.

[0032] Next, as Figure 1 As shown in (b), the transfer roller 4 rotates to pull in the front end of the sheet member 10, and the conveyor section 5a, on which the stacked member 11 is placed, moves toward the X-axis + side. Then, the front end of the sheet member 10, located near the Z-axis - end of the transfer roller 4 (i.e., at the 6 o'clock position when viewed from the Y-axis + side), is adhered to the stacked member 11 in the second region 4c of the transfer roller 4. At this time, it is preferable to apply an adhesive or the like to the Z-axis + side surface of the stacked member 11. Then, the transfer roller 4 rotates, and the conveyor section 5a moves toward the X-axis + side to pull in and stack the sheet member 10 onto the stacked member 11. At this time, the transfer speed of the transfer roller 4 on the sheet member 10 and the moving speed of the conveyor section 5a can be synchronized with the conveying speed of the anvil roller 2 on the sheet member 10.

[0033] Here, as the transfer roller 4 rotates, the second portion 4e and the first portion 4d of the second region 4c extend beyond the Z-axis side of the transfer roller 4. The second portion 4e and the first portion 4d of the second region 4c are sequentially switched from an air-suction state to an air-ejection state. Thus, both the first region 4b and the second region 4c of the transfer roller 4 are in an air-ejection state. Therefore, by rotating the transfer roller 4 at a speed faster than the conveying speed of the sheet member 10, for example, the second region 4c of the transfer roller 4 can be positioned near the Z-axis+ side end of the transfer roller 4 in its standby state (i.e., near the 12 o'clock position when viewed from the Y-axis+ side).

[0034] Next, as Figure 1As shown in (c), the cutting roller 3 rotates synchronously with the conveying speed of the anvil roller 2 to the sheet member 10. At the position where the cutting blade 3b of the cutting roller 3 is closest to the anvil roller 2, the sheet member 10 is cut by the cutting blade 3b of the cutting roller 3. Thus, the sheet member 10 is divided into a cut sheet member 10a and a subsequent sheet member 10b. Furthermore, when the transfer roller 4 rotates and the rear end of the cut sheet member 10a is positioned near the end of the anvil roller 2 on the X-axis + side, the second portion 4e of the second region 4c of the transfer roller 4 is positioned on the X-axis - side, and the first portion 4d and the second portion 4e of the second region 4c of the transfer roller 4 are switched from an air ejection state to an air suction state. At this time, the attraction force of the second portion 4e of the second region 4c of the transfer roller 4 on the rear end of the cut sheet member 10a is set to be stronger than the attraction force of the anvil roller 2 on the rear end of the cut sheet member 10a.

[0035] Thus, the rear end of the cut sheet member 10a is attracted to the second portion 4e of the second region 4c of the transfer roller 4 and transferred from the anvil roller 2 to the transfer roller 4. Then, the transfer roller 4 rotates, and when the front end of the subsequent sheet member 10b is positioned near the end of the anvil roller 2 on the X-axis + side, the first portion 4d of the second region 4c of the transfer roller 4 is positioned on the X-axis - side. At this time, the attraction of the first portion 4d of the second region 4c of the transfer roller 4 to the front end of the subsequent sheet member 10b is set to be stronger than the attraction of the anvil roller 2 to the front end of the subsequent sheet member 10b. Thus, the front end of the subsequent sheet member 10b is attracted to the first portion 4d of the second region 4c of the transfer roller 4 and transferred from the anvil roller 2 to the transfer roller 4.

[0036] Next, the transfer roller 4 rotates. When the rotation angle of the transfer roller 4 exceeds a predetermined threshold value below the distance between the rear end of the cut sheet member 10a and the stacked member 11 placed on the conveyor section 5a, such as... Figure 1 As shown in (d), the second portion 4e of the second region 4c is switched from an air-attracting state to an air-ejecting state. Consequently, the entire region on the transfer roller 4, including the first region 4b, which is opposite to the cut sheet member 10a, becomes an air-ejecting state. That is, the cut sheet member 10a does not contact the transfer roller 4.

[0037] In this state, the conveying unit 5a accelerates at a preset acceleration. As a result, the cut sheet member 10a is conveyed at high speed by the conveying unit 5a, and can be separated from the subsequent sheet member 10b by a preset interval at the rear end of the cut sheet member 10a. Therefore, a spacing, for example, that allows the cut sheet member 10a to be well stacked on top of the stacked members 11 that are sequentially conveyed towards the X-axis + side can be established between the cut sheet member 10a and the subsequent sheet member 10b. At this time, by appropriately changing the acceleration of the conveying unit 5a, the separation interval between the cut sheet member 10a and the subsequent sheet member 10b can be easily changed. Then, return. Figure 1 In state (a), by repeating the above process, the cut sheet member 10a can be stacked on the stacked member 11 that is sequentially conveyed toward the X-axis + side.

[0038] Thus, the separation device 1 of this embodiment is configured such that the front end of the sheet member 10 is conveyed to the conveying section 5a in a state where it is adsorbed onto the second region 4c of the transfer roller 4. Then, while the transfer roller 4 rotates and air is ejected from the entire region of the transfer roller 4 opposite the cut sheet member 10a, the conveying section 5a accelerates at a predetermined acceleration. Therefore, a spacing can be created between the cut sheet member 10a and the subsequent sheet member 10b, for example, a spacing that allows the cut sheet member 10a to be well stacked on top of the stacked members 11 that are sequentially conveyed towards the X-axis + side. At this time, by appropriately changing the acceleration of the conveying section 5a, the separation interval between the cut sheet member 10a and the subsequent sheet member 10b can be easily changed. Furthermore, when the conveying section 5a accelerates, the cut sheet member 10a does not contact the transfer roller 4. Therefore, damage to the cut sheet member 10a can be suppressed, and the sheet member 10 can be separated. Furthermore, without using a large device like the four-roller lamination device of Patent Document 1, the sheet-like member 10 can be separated by the movement of the conveyor section 5a. Therefore, the separation device 1 can be miniaturized.

[0039] <Implementation Method 2>

[0040] Figure 2 (a) to Figure 2 Figure (c) is a diagram illustrating the separation of the sheet-like member in the separation apparatus of this embodiment. Furthermore, the separation apparatus 21 of this embodiment is as follows... Figure 2 (a) to Figure 2 As shown in (c), it has a structure that is substantially the same as the separation device 1 in Embodiment 1, so repeated descriptions are omitted, but the anvil roller 22 is shared with the transfer roller. Figure 2As shown in (a), the anvil roller 22 is positioned relative to the cutting roller 3 on the X-axis + side and the Z-axis - side. The anvil roller 22 has a roller portion 22a. The roller portion 22a includes, for example, a cutting board area 22b, a first area 22c, and a second area 22d.

[0041] like Figure 2 As shown in (a), the cutting board area 22b is located on the roller portion 22a, opposite to the cutting blade 3b of the cutting roller 3, when cutting the sheet member 10. For example, it can be configured such that the roller portion 22a will not be damaged by the cutting blade 3b. Therefore, the cutting board area 22b can be made of resin, for example, or have a retraction groove formed for the front end of the cutting blade 3b of the cutting roller 3 to retract. The first area 22c has the same structure as the first area 4b of the transfer roller 4 in Embodiment 1. The second area 22d is configured to be substantially the same as the second area 4c of the transfer roller 4 in Embodiment 1, but in the rotation direction of the anvil roller 22, the first portion 22e and the second portion 22f are clamped into the cutting board area 22b.

[0042] Using such a separation device 21, the sheet member 10 is separated as follows. Here, the process of cutting and separating the sheet member 10, whose front end has been attached to the stacked member 11, will be described in the following description. First, while the sheet member 10, which is being conveyed toward the X-axis, is being wound along the anvil roller 22 from which air is ejected from the first region 22c and the second region 22d, it is pulled to a predetermined length by the conveying section 5a, and the cutting roller 3 and the anvil roller 22 rotate in a manner synchronized with the conveying speed of the sheet member 10 by the conveying section 5a.

[0043] Then, as Figure 2 As shown in (a), at the position where the cutting blade 3b of the cutting roller 3 is closest to the cutting board area 22b of the anvil roller 22, the first portion 22e and the second portion 22f of the second region 22d of the anvil roller 22 are switched from an air ejection state to an air attraction state. With the sheet member 10 adsorbed onto the first portion 22e and the second portion 22f of the second region 22d of the anvil roller 22, the cutting blade 3b of the cutting roller 3 cuts the sheet member 10. Thus, the sheet member 10 is divided into a cut sheet member 10a and a subsequent sheet member 10b. At this time, the front end of the subsequent sheet member 10b is adsorbed onto the first portion 22e of the second region 22d of the anvil roller 22, and the rear end of the cut sheet member 10a is adsorbed onto the second portion 22f of the second region 22d of the anvil roller 22.

[0044] Next, the cutting roller 3 and the anvil roller 22 rotate, and the conveying section 5a moves. When the rotation angle of the anvil roller 22 exceeds a predetermined threshold value below the distance between the rear end of the cut sheet member 10a and the stacked member 11 placed on the conveying section 5a, such as... Figure 2As shown in (b), the second portion 22f of the second region 22d is switched from an air-attracting state to an air-ejecting state. Thus, the entire region on the anvil roller 22, including the first region 22c, of the portion opposite the cut sheet member 10a, becomes an air-ejecting state. That is, the cut sheet member 10a does not contact the anvil roller 22.

[0045] In this state, the conveying unit 5a accelerates at a preset acceleration. As a result, the cut sheet member 10a is conveyed at high speed by the conveying unit 5a, and can be separated from the subsequent sheet member 10b by a preset interval at the rear end of the cut sheet member 10a. Therefore, a spacing, for example, that allows the cut sheet member 10a to be well stacked on top of the stacked members 11 that are sequentially conveyed towards the X-axis + side can be established between the cut sheet member 10a and the subsequent sheet member 10b. At this time, by appropriately changing the acceleration of the conveying unit 5a, the separation interval between the cut sheet member 10a and the subsequent sheet member 10b can be easily changed.

[0046] Next, with the leading end of the subsequent sheet member 10b adsorbed onto the first portion 22e of the second region 22d of the anvil roller 22, as follows: Figure 2 As shown in (c), the anvil roller 22 rotates and pulls in the front end of the sheet member 10. At the same time, the conveyor section 5a, on which the next member to be stacked 11 is placed, moves toward the X-axis + side. Then, the front end of the subsequent sheet member 10b, located near the end of the anvil roller 22 on the Z-axis - side, is attached to the member to be stacked 11 in the first portion 22e of the second region 22d of the anvil roller 22.

[0047] Next, the anvil roller 22 rotates, and the conveying section 5a moves towards the X-axis + side, pulling in the sheet member 10 and stacking it on the stacked member 11. At this time, for example, if the anvil roller 22 rotates and the first portion 22e of the second region 22d exceeds the end of the anvil roller 22 on the Z-axis - side, the air suction state can be switched to the air ejection state. Thus, both the first region 22c and the second region 22d of the anvil roller 22 are in the air ejection state.

[0048] Therefore, the subsequent sheet member 10b can be pulled in without contacting the anvil roller 22 or the cutting roller 3. This allows large sheet members 10 to be stacked on top of the stacked member 11. Afterwards, if the subsequent sheet member 10b is pulled to a predetermined length, it returns to its original position. Figure 2 In state (a), the subsequent sheet member 10b is cut off. By repeating the above process, the cut sheet member 10a can be stacked on the stacked member 11 that is sequentially conveyed to the X-axis + side.

[0049] Thus, the separation device 21 of this embodiment can easily change the separation interval between the cut sheet member 10a and the subsequent sheet member 10b by appropriately varying the acceleration of the conveying section 5a. Furthermore, the separation device 21 of this embodiment can create a non-contact period during the time from when the front end of the sheet member 10 is transferred to the conveying section 5a until the sheet member 10 is cut to form the rear end of the sheet member 10, during which the sheet member 10b does not contact the anvil roller 22 or the cutting roller 3. Therefore, large sheet members 10 corresponding to the movement amount of the conveying section 5a can be stacked on the stacked member 11.

[0050] <Implementation Method 3>

[0051] Figure 3 (a) to Figure 3 (d) is a diagram illustrating the separation of the sheet-like member in the separation apparatus of this embodiment. Furthermore, the separation apparatus 31 of this embodiment is as follows... Figure 3 (a) to Figure 3 As shown in (d), the structure is substantially the same as that of the separation device 1 in Embodiment 1, so repeated descriptions are omitted. Figure 3 As shown in (a), in addition to the cutting roller 3 and the transfer roller 4 of the separation device 1 of Embodiment 1, the separation device 31 also has an anvil roller 32 with a structure that is substantially the same as that of the anvil roller 22 of the separation device 21 of Embodiment 2.

[0052] like Figure 3 As shown in (a), the anvil roller 32 also includes a roller portion 32a. Furthermore, the roll portion 32a includes a second region 32d, which has a cutting board region 32b, a first region 32c, a first portion 32e, and a second portion 32f. Similar to the anvil roller 2 in Embodiment 1, the anvil roller 32 is positioned on the Z-axis side relative to the cutting roller 3 and on the X-axis side relative to the transfer roller 4.

[0053] Using such a separation device 31, the sheet-like component 10 is separated as follows. First, with the front end of the sheet-like component 10 adsorbed onto the first portion 32e of the second region 32d of the anvil roller 32, the anvil roller 32 rotates, conveying the sheet-like component 10. Then, as... Figure 3As shown in (a), when the front end of the sheet member 10 is positioned near the end of the anvil roller 2 on the X-axis + side, the first portion 4d of the second region 4c of the transfer roller 4 is positioned on the X-axis - side, and the first portion 4d and the second portion 4e of the second region 4c of the transfer roller 4 are switched from an air ejection state to an air suction state. At this time, the first portion 32e of the second region 32d of the anvil roller 32 can be switched from an air suction state to an air ejection state. As a result, the front end of the sheet member 10 is adsorbed onto the first portion 4d of the second region 4c of the transfer roller 4 and transferred from the anvil roller 32 to the transfer roller 4.

[0054] Next, as Figure 3 As shown in (b), the transfer roller 4 rotates and pulls in the front end of the sheet member 10. Simultaneously, the conveyor section 5a, on which the member to be stacked 11 is placed, moves towards the X-axis + side. Then, the front end of the sheet member 10, located near its Z-axis - end on the transfer roller 4, is adhered to the member to be stacked in the second region 4c of the transfer roller 4. At this time, the anvil roller 32 rotates, and the portion of the anvil roller 32 opposite to the sheet member 10 becomes the first region 32c.

[0055] Then, the transfer roller 4 rotates, and the conveying section 5a moves towards the X-axis + side to pull in the sheet member 10 and stack it on the stacked member 11. Here, as the transfer roller 4 rotates, the second portion 4e and the first portion 4d of the second region 4c extend beyond the Z-axis - side end of the transfer roller 4, and the second portion 4e and the first portion 4d of the second region 4c are sequentially switched from an air suction state to an air ejection state. As a result, the entire area of ​​the anvil roller 32 and the transfer roller 4 opposite to the sheet member 10 becomes an air ejection state, and the sheet member 10 is in a non-contact state with the anvil roller 32 and the transfer roller 4. Therefore, damage to the sheet member 10 during the pulling in process can be suppressed.

[0056] The sheet member 10 is pulled to a predetermined length by the conveying section 5a, and the cutting roller 3 and the anvil roller 32 rotate in a manner synchronized with the conveying speed of the conveying section 5a on the sheet member 10. Then, as... Figure 3As shown in (c), near the position where the cutting blade 3b of the cutting roller 3 is closest to the cutting board area 32b of the anvil roller 32, the first portion 32e and the second portion 32f of the second region 32d of the anvil roller 32 are switched from an air ejection state to an air attraction state. With the sheet member 10 adsorbed onto the first portion 32e and the second portion 32f of the second region 32d of the anvil roller 32, the cutting blade 3b of the cutting roller 3 cuts the sheet member 10. Thus, the sheet member 10 is divided into a cut sheet member 10a and a subsequent sheet member 10b. At this time, the front end of the subsequent sheet member 10b is adsorbed onto the first portion 32e of the second region 32d of the anvil roller 32, and the rear end of the cut sheet member 10a is adsorbed onto the second portion 32f of the second region 32d of the anvil roller 32.

[0057] Next, as the transfer roller 4 and anvil roller 32 rotate, and the rear end of the cut sheet member 10a is positioned near the end of the anvil roller 32 on the X-axis + side, the second portion 4e of the second region 4c of the transfer roller 4 is positioned near the X-axis - side of the transfer roller 4, and the first portion 4d and the second portion 4e of the second region 4c of the transfer roller 4 are switched from an air ejection state to an air suction state. At this time, the second portion 32f of the second region 32d of the anvil roller 32 can be switched from an air suction state to an air ejection state. As a result, the rear end of the cut sheet member 10a is well adsorbed onto the second portion 4e of the second region 4c of the transfer roller 4 and transferred from the anvil roller 32 to the transfer roller 4.

[0058] Then, the transfer roller 4 and the anvil roller 32 rotate, and when the front end of the subsequent sheet member 10b is positioned near the end of the anvil roller 32 on the X-axis + side, the first portion 4d of the second region 4c of the transfer roller 4 is positioned on the X-axis - side of the transfer roller 4. At this time, the first portion 32e of the second region 32d of the anvil roller 32 can switch from an air suction state to an air ejection state. As a result, the front end of the subsequent sheet member 10b is well adsorbed onto the first portion 4d of the second region 4c of the transfer roller 4 and is well transferred from the anvil roller 2 to the transfer roller 4.

[0059] Next, the transfer roller 4 and the anvil roller 32 rotate. When the rotation angle of the transfer roller 4 exceeds a predetermined threshold value below the distance between the rear end of the cut sheet member 10a and the stacked member 11 placed on the conveyor section 5a, such as... Figure 3 As shown in (d), the second portion 4e of the second region 4c of the transfer roller 4 is switched from an air-suction state to an air-ejection state. Thus, the entire region of the transfer roller 4, including the first region 4b, which is the portion opposite the cut sheet member 10a, becomes an air-ejection state. That is, the cut sheet member 10a does not contact the transfer roller 4.

[0060] In this state, the conveying unit 5a accelerates at a preset acceleration. As a result, the cut sheet member 10a is conveyed at high speed by the conveying unit 5a, and can be separated from the subsequent sheet member 10b by a preset interval at the rear end of the cut sheet member 10a. Therefore, a spacing, for example, that allows the cut sheet member 10a to be well stacked on top of the stacked members 11 that are sequentially conveyed towards the X-axis + side can be established between the cut sheet member 10a and the subsequent sheet member 10b. At this time, by appropriately changing the acceleration of the conveying unit 5a, the separation interval between the cut sheet member 10a and the subsequent sheet member 10b can be easily changed. Then, return. Figure 3 In state (a), by repeating the above process, the cut sheet member 10a can be stacked on the stacked member 11 that is sequentially conveyed toward the X-axis + side.

[0061] Thus, the separation device 31 of this embodiment can easily change the separation interval between the cut sheet member 10a and the subsequent sheet member 10b by appropriately varying the acceleration of the conveying section 5a. Furthermore, the separation device 31 of this embodiment can also create a non-contact period during which the sheet member 10b does not contact the cutting roller 3, the transfer roller 4, and the anvil roller 32 from the time the front end of the sheet member 10 is passed to the conveying section 5a until the sheet member 10 is cut to form the rear end of the sheet member 10. Therefore, large sheet members 10 corresponding to the movement amount of the conveying section 5a can be stacked on the stacked member 11. Furthermore, in Embodiment 2, the separating device 21 cannot cut the sheet member 10 unless the transfer of the sheet member 10 to the conveying unit 5a is completed. However, in this embodiment, the separating device 31, since the transfer roller 4 and the anvil roller 32 are separated, can cut the sheet member 10 before the transfer of the sheet member 10 to the conveying unit 5a is completed, and can also stack small sheet members 10 on the stacked member 11. Therefore, for example, the anvil roller 32 may also have multiple cutting board areas 32b and a second area 32d.

[0062] This disclosure is not limited to the above embodiments, and appropriate modifications can be made without departing from the spirit of the invention. For example, the second region of the transfer roller and anvil roller in the above embodiments has a second portion, but it may also be omitted.
