Abstract

To provide a processing device which can suitably recover an end material generating in cutting a band-like sheet member.SOLUTION: In a processing device 100, when a cutting part 20 cuts a sheet member 50, a desired-shaped electrode 51 is formed and an end material 52 as an unnecessary member is generated. The electrode 51 is sucked and conveyed by a conveying surface 21a of a conveying part 21. On the other hand, the end material 52 is recovered by a recovering part 22. The recovering part 22 recovers the end material 52 when the end material 52 is sucked in an opposite direction to a direction which the conveying part 21 sucks the electrode 51. Thus, the end material 52 is suppressed from being sucked and conveyed together with the electrode 51 by the conveying part 21 as the recovery part 22 sucks the end material 52 in an opposite direction to the conveying part 21.SELECTED DRAWING: Figure 3

Description

  The present invention relates to a processing apparatus.

  As a processing apparatus for recovering the end material generated by cutting the belt-shaped sheet member, for example, one described in Patent Document 1 is known. Patent Document 1 describes an apparatus that includes a conveyance unit that conveys a sheet member and a cutting unit that cuts the sheet member. An object is formed when the cutting part cuts the sheet member, and an excessive portion is generated as an end material. In this apparatus, the cut object and the end material are conveyed by the conveyance unit, and the object is adsorbed and held, while the end material is dropped from the conveyance unit to collect the end material.

Japanese Patent No. 5903886

  However, in the apparatus of Patent Document 1, the end material may not be recovered well due to the end material adsorbed together with the object.

  The objective of this invention is providing the processing apparatus which can collect | recover the end materials generated by cut | disconnecting a strip | belt-shaped sheet member suitably.

  The processing apparatus which concerns on 1 aspect of this invention is a processing apparatus which processes by cut | disconnecting a strip | belt-shaped sheet member, Comprising: The cutting part which cut | disconnects a sheet member and forms a target object, A target object is on a conveyance surface And a transport unit that sucks and transports an object on the transport surface, and a recovery unit that recovers scraps generated by cutting the sheet member at the cutting unit. A recovery unit that recovers the end material by adsorbing the end material in a direction opposite to the direction in which the object is adsorbed;

  In such a processing apparatus, the cutting part cuts the sheet member, whereby an object having a desired shape is formed, and an end material is generated as an unnecessary member. Among these, the target object is sucked and transported by the transport surface of the transport unit. On the other hand, the mill ends are collected by the collection unit. Here, the collection unit collects the end material by adsorbing the end material in a direction opposite to the direction in which the transport unit adsorbs the object. As described above, the collection unit adsorbs the end material in the direction opposite to the conveyance unit, so that it is possible to suppress the end material from being adsorbed and conveyed to the conveyance unit together with the object. As described above, the end material generated by cutting the belt-shaped sheet member can be suitably recovered.

  The recovery unit may include an adsorption portion that adsorbs the end material, and a separation portion that separates the adsorbed end material by discharging gas at a position different from the adsorption portion. Thereby, the collection | recovery part can detach | separate the end material which adsorb | sucked and collect | recovered in the detachment | leave part. Therefore, the recovery unit can put the recovered scrap material into a recovery box or the like and then recover a new scrap material.

  The collection unit may have an adsorption region in which the end material is adsorbed in the adsorption part and a non-adsorption region in which the adsorption is not performed in a direction orthogonal to the transport direction. For the sheet member to be conveyed, a non-adsorption region is disposed at a position where the object passes, and an adsorption region is disposed at a position where the end material passes. Thereby, the collection | recovery part can suppress adsorbing | sucking a target object accidentally in a non-adsorption area | region, adsorb | sucking and recovering scraps in an adsorption | suction area | region.

  The suction region may be formed discontinuously along the transport direction. As a result, when a part of the object extends to the suction area side, the object is erroneously adsorbed by the collection unit by adjusting the part so that the part is located at a location where the adsorption area is interrupted. Can be suppressed.

  The cutting part may cut the end material as an individual member separated from other end materials. In this manner, the end material is cut as an individual member, so that the recovery unit can easily recover the end material.

  ADVANTAGE OF THE INVENTION According to this invention, the processing apparatus which can collect | recover the end material generated by cut | disconnecting a strip | belt-shaped sheet member can be provided.

The positive terminal 4 is fixed to the case 2 via an insulating ring 6, and the negative terminal 5 is fixed to the case 2 via an insulating ring 7.

  An insulating film F is disposed between the electrode assembly 3 and the inner side surface and bottom surface of the case 2, and the case 2 and the electrode assembly 3 are insulated by the insulating film F. The lower end of the electrode assembly 3 is in contact with the bottom surface inside the case 2 via the insulating film F. By arranging the spacer S between the electrode assembly 3 and the case 2, a gap is filled between the electrode assembly 3 and the case 2. The spacer S includes one or a plurality of sheets, and the number of the sheets can vary depending on the thickness of the electrode assembly 3.

  The electrode assembly 3 has a structure in which a plurality of positive electrodes 8 and a plurality of negative electrodes 9 are alternately stacked via a bag-shaped separator 10. The positive electrode 8 is wrapped in a bag-like separator 10. The positive electrode 8 wrapped in the bag-shaped separator 10 is configured as a positive electrode 11 with a separator. Therefore, the electrode assembly 3 has a structure in which a plurality of separator-attached positive electrodes 11 and a plurality of negative electrodes 9 are alternately stacked.

  The positive electrode 8 includes a metal foil 14 that is a positive electrode current collector made of, for example, an aluminum foil, and a positive electrode active material layer 15 formed on both surfaces of the metal foil 14. The metal foil 14 has a foil body portion 14a having a rectangular shape in plan view, and a tab 14b integrated with the foil body portion 14a. The tab 14b protrudes from the edge in the vicinity of one end of the foil body 14a and penetrates the separator 10. The tab 14 b is connected to the positive electrode terminal 4 through the conductive member 12. In FIG. 2, the tab 14b is omitted for convenience.

  The positive electrode active material layer 15 is formed on both surfaces of the foil main body portion 14a.

The tab 16b protrudes from the edge in the vicinity of one end of the foil body 16a. The tab 16 b is connected to the negative electrode terminal 5 through the conductive member 13. In FIG. 2, the tab 16b is omitted for convenience.

  The negative electrode active material layer 17 is formed on both surfaces of the foil main body portion 16a. The negative electrode active material layer 17 is a porous layer formed including a negative electrode active material and a binder. Examples of the negative electrode active material include carbon such as graphite, highly oriented graphite, mesocarbon microbeads, hard carbon, and soft carbon, alkali metals such as lithium and sodium, metal compounds, SiOx (0.5 ≦ x ≦ 1.5 ) And the like or boron-added carbon.

  The separator 10 has a rectangular shape in plan view. Examples of the material of the separator 10 include a porous film made of a polyolefin-based resin such as polyethylene (PE) and polypropylene (PP), or a woven or non-woven fabric made of polypropylene, polyethylene terephthalate (PET), methylcellulose, or the like.

  When the power storage device 1 configured as described above is manufactured, first, the separator-attached positive electrode 11 and the negative electrode 9 in which the positive electrode 8 is wrapped by the bag-like separator 10 are manufactured, and then the separator-attached positive electrode 11 and the negative electrode 9 Are alternately laminated, and the positive electrode 11 with separator and the negative electrode 9 are fixed with a tape or the like to obtain the electrode assembly 3. Then, the tab 14b of the positive electrode 11 with the separator is connected to the positive electrode terminal 4 through the conductive member 12, and the tab 16b of the negative electrode 9 is connected to the negative electrode terminal 5 through the conductive member 13, and then the electrode assembly 3 is attached to the case. 2 to accommodate.

  A processing apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. FIG. 3 is a schematic side view showing the processing apparatus 100. FIG. 4 is a plan view of the conveying unit 21 that conveys the cut sheet member as viewed from above. FIG. 5 is a perspective view of the vicinity of the end of the collection unit 22. FIG. 6 is a diagram in which the outer peripheral surface of the collection unit 22 is virtually developed in a planar shape. The processing apparatus 100 is an apparatus that cuts a strip-shaped sheet member and collects the end material generated by the cutting. As shown in FIG. 3, the processing apparatus 100 includes a cutting unit 20, a transport unit 21, a collection unit 22, and a collection box 23.

  The cutting part 20 is a part that cuts the sheet member 50 to form the electrode 51. The cutting unit 20 includes an upper roller 20A disposed on the upper side and a lower roller 20B disposed on the lower side. The upper roller 20A is a so-called rotary cutter having a blade portion for cutting the sheet member 50 into a desired shape on the outer peripheral surface. The lower roller 20B is a so-called anvil roll that faces the upper roller 20A and sandwiches the sheet member 50 from below. The cutting unit 20 cuts the sheet member 50 supplied from the supply roll 24 and sent out by the pair of nip rollers 25. The blade portion of the upper roller 20A is formed in a predetermined pattern on the outer peripheral surface of the upper roller 20A so as to cut the sheet member 50 into a desired shape as it rotates and feeds the sheet member 50 in the transport direction D1. . The material of the sheet member 50 is the material of the positive electrode 8 when the positive electrode 8 is formed as the object, and the material of the negative electrode 9 is employed when the negative electrode 9 is formed as the object.

  Here, with reference to FIG. 4, the cutting shape of the sheet | seat member 50 by the cutting part 20 is demonstrated. The cutting part 20 forms an electrode 51 as an object to be cut. Further, when the cutting unit 20 cuts the sheet member 50 into the shape of the electrode 51, an excess portion is generated as the end material 52. In addition, the cutting part 20 forms the electrode 51 and the end material 52 by putting a cut line in the sheet member 50. However, in a state where the cutting unit 20 is transported by the transport unit 21 after cutting, the respective electrodes 51 and end materials are formed. The members 52 are connected to each other on the cut line (that is, they are not separated from each other and are not separated, and even if they are separated, they are in a range of errors). This makes it possible to align the suction area and the non-suction area of the transport unit 21 and the recovery unit 22 described later. The electrode 51 may be any of the positive electrode 8 and the negative electrode 9 described above. The electrode 51 has a foil body 51a and a tab 51b. The cutting part 20 forms the electrode 51 in the sheet member 50 so that the electrode 51 is arranged in a row in the transport direction D1. Further, the cutting unit 20 cuts the sheet member 50 so that the rows of the electrodes 51 are two in the width direction D2 orthogonal to the transport direction D1. One column in the width direction D2 is referred to as LA, and the other column is referred to as LB. The foil main body 51a of the electrode 51 has a side 51c from which the tab 51b protrudes, a side 51d arranged to face the side 51c, and sides 51e and 51f orthogonal to the sides 51c and 51d.

  In each row LA, LB, the electrode 51 is oriented such that the tab 51b protrudes to the outside in the width direction D2, that is, to the side edge portions 50a, 50b side of the sheet member 50. The side 51c of the electrode 51 of the row LA is located on the side edge portion 50a side in the width direction D2. The side 51c of the electrode 51 in the row LB is located on the other side edge portion 50b side in the width direction D2. In the row LA, the side 51e of the electrode 51 in the transport direction D1 is connected to the side 51f of the electrode 51 adjacent to the upstream side in the transport direction D1. In the row LB, the side 51f of the electrode 51 in the transport direction D1 is connected to the side 51e of the electrode 51 adjacent to the upstream side in the transport direction D1. The electrode 51 of the row LA and the electrode 51 of the row LB are continuous with each other at the center position in the width direction D2 of the sheet member 50. The side 51e of the electrode 51 in the row LA and the side 51f of the electrode 51 in the row LB are arranged at the same position in the transport direction D1. The side 51e of the electrode 51 in the row LA and the side 51f of the electrode 51 in the row LB are arranged at the same position in the transport direction D1.

  The end material 52 is formed between the tab 51b of one electrode 51 and the tab 51b of another electrode 51 adjacent to the electrode 51 in the transport direction D1. That is, in the row LA, the end material 52 is formed along one side edge portion 50a in the width direction D2 of the sheet member 50. The end material 52 of the row LA is formed in a rectangular shape that is long in the transport direction D1 by the side edge portion 50a, the side 51c of the electrode 51, and the side of the tab 51b. In the row LB, the end material 52 is formed along the other side edge portion 50b in the width direction D2 of the sheet member 50. The end material 52 of the row LB is formed in a rectangular shape that is long in the transport direction D1 by the side edge portion 50b, the side 51c of the electrode 51, and the side of the tab 51b. The cutting part 20 cuts the end material 52 as an individual member separated from the other end material 52. That is, the end material 52 is separated from other end materials 52 adjacent to each other in the transport direction D1 at the position of the tab 51b. That is, the end material 52 is formed discontinuously in the transport direction D1.

  As shown in FIG. 3, the conveyance part 21 arrange | positions the electrode 51 on the conveyance surface 21a, and adsorb | sucks and conveys the electrode 51 to the said conveyance surface 21a. The conveyance unit 21 is configured by a belt conveyor including an endless belt 30 formed in a belt shape and a roller 32 that guides and drives the belt 30. A suction device 31 is provided on the inner peripheral side of the belt 30 of the transport unit 21 at a position corresponding to the transport surface 21a. The suction device 31 generates suction force downward on the transport surface 21a by sucking air on the back side of the belt 30 constituting the transport surface 21a. The suction device 31 sucks air through a plurality of fine through holes formed on the transport surface 21a. Thereby, the electrode 51 arrange | positioned on the conveyance surface 21a is conveyed in the state adsorb | sucked to the said conveyance surface 21a. The transport unit 21 transports the plurality of electrodes 51 arranged in the rows LA and LB (see FIG. 4). In addition, the conveyance part 21 also conveys the end material 52 with the electrode 51 in the upstream in the conveyance direction D1 rather than the collection | recovery part 22. FIG.

  As shown in FIG. 4, the transport surface 21 a has a suction region 36 and a non-suction region 37 in the width direction D2. In the figure, the hatched portion corresponds to the suction region 36. In the suction area 36, the suction device 31 performs suction on the back side of the transport surface 21a, and the transport surface 21a has a plurality of fine through holes for flowing air, so that suction force is generated. Yes. In the non-adsorption region 37, no suction force is generated because the suction device 31 is not provided, the suction device 31 does not operate, or no through-hole is formed in the transport surface 21a. The suction region 36 is formed in a region of the transport surface 21a through which the foil body 51a of the electrodes 51 in the rows LA and LB passes. As a result, the transport surface 21 a sucks the foil body 51 a of the electrode 51 in the suction region 36. The non-adsorption region 37 is formed in a region of the transport surface 21a through which the end members 52 of the rows LA and LB pass. That is, the non-adsorption region 37 is formed on both end sides in the width direction D2 of the adsorption region 36. Thereby, the conveyance surface 21a conveys the tab 51b of the electrode 51 and the end material 52 in the non-adsorption region 37 without being adsorbed. In addition, it is good also considering the part by which the tab 51b of the electrode 51 is arrange | positioned as an adsorption | suction area | region among the area | regions near both the edge parts of the width direction D2 of the conveyance surface 21a. In this case, the non-suction area 37 corresponding to the position of the end material 52 and the suction area corresponding to the position of the tab 51b are alternately arranged in the transport direction D1. As a specific example, an area where the suction device 31 performs suction is expanded to the position of the tab 51b, and a through hole is disposed at a position corresponding to the tab 51b of the transport surface 21a. However, in this case, the control unit (not shown) synchronizes between the cutting timing of the cutting unit 20 and the conveyance position and conveyance speed of the conveyance unit 21, and the end material 52 is arranged in the non-adsorption region 37. It is necessary to make settings.

  As shown in FIG. 3, the collection unit 22 is a roller-like device that is disposed at a position facing the conveyance surface 21 a of the conveyance unit 21 and collects the end material 52 on the conveyance surface 21 a. The collection unit 22 rotates in accordance with the conveyance of the sheet member 50 while sandwiching the cut sheet member 50 between the outer circumferential surface 22a and the conveyance surface 21a. The collection unit 22 rotates so that the outer peripheral surface 22a on the lower end side moves in the transport direction D1. The collection unit 22 collects the end material 52 by adsorbing the end material 52 in a direction opposite to the direction in which the transport unit 21 adsorbs the electrode 51. Here, since the transport unit 21 sucks the electrode 51 downward, the collection unit 22 sucks the end material 52 upward.

  The collection unit 22 has an adsorption portion 44 and a separation portion 45. The suction portion 44 and the separation portion 45 are formed at different positions in the circumferential direction on the outer peripheral surface 22a of the collection unit 22. The suction portion 44 is a portion that is formed in a position facing the transport surface 21 a, that is, a region on the lower end side of the collection unit 22, and sucks the end material 52. The collection unit 22 adsorbs the end material 52 conveyed on the conveyance surface 21a at the adsorption portion 44, and moves the adsorbed end material 52 upward from the conveyance surface 21a as the collection unit 22 rotates. Remove it. The separation portion 45 is a portion that separates the adsorbed end material 52 by discharging gas at a position different from the adsorption portion 44. The separation portion 45 is disposed on the downstream side in the rotational direction from the position where the suction portion 44 sucks the end material 52 on the transport surface 21a. In the present embodiment, the separation portion 45 is provided at a position above the suction portion 44. A collection box 23 is provided at a position adjacent to the separation portion 45. Therefore, the end material 52 separated from the collection unit 22 by the separation part 45 falls into the collection box 23 and is stored in the collection box 23.

  Specifically, the collection unit 22 rotates in the rotation direction D3 around the central axis, and the suction is arranged in a region on the lower end side inside the cylindrical member 40 in which many fine through holes are formed. The apparatus 41 and the discharge apparatus 42 arrange | positioned in the area | region of the upper end side inside the cylindrical member 40 are provided. The suction device 41 generates suction force on the outer peripheral surface 22a toward the inner peripheral side by sucking air on the back side of the cylindrical member 40 constituting the outer peripheral surface 22a. The suction device 41 has a plurality of fine through holes formed on the wall surface facing the outer peripheral surface 22 a, and sucks air through the through holes of the cylindrical member 40 and the through holes of the suction device 41. Thereby, the end material 52 which contacted the outer peripheral surface 22a is collect | recovered in the state adsorb | sucked to the said outer peripheral surface 22a. The suction device 41 has a suction surface that draws a semicircular arc in the lower half region of the cylindrical member 40. Therefore, a portion of the cylindrical member 40 that has moved to a position corresponding to the suction surface of the suction device 41 functions as the suction portion 44. The discharge device 42 has a plurality of fine through holes formed on the wall surface facing the cylindrical member 40, and discharges air on the back side of the cylindrical member 40, thereby passing through the through holes of the discharge device 42 and the through holes of the cylindrical member 40. Then, pressure is generated on the outer peripheral surface 22a toward the outer peripheral side. The discharge device 42 discharges air through a plurality of fine through holes formed in the outer peripheral surface 22a. Thereby, the end material 52 adsorbed on the outer peripheral surface 22a is separated to the outer peripheral side together with the air discharged by the discharge device 42. The discharge device 42 has a discharge surface that draws a quarter-circular arc at a position downstream of the conveyance direction D <b> 1 in the upper half region of the cylindrical member 40. Therefore, a portion of the cylindrical member 40 that has moved to a position corresponding to the discharge surface of the discharge device 42 functions as the separation portion 45.

  The operation of the collection unit 22 having the above configuration will be described. The predetermined location in the circumferential direction of the cylindrical member 40 moves around in the rotational direction D3 as the cylindrical member 40 rotates. When the predetermined portion rotates to the position of the suction device 41, suction force is generated by the suction of the suction device 41 and functions as the suction portion 44. Therefore, the end material 52 is adsorbed when the predetermined portion rotates to a position facing the transport surface 21a. When the predetermined portion further rotates with the end material 52 adsorbed, the position reaches the position of the discharge device 42. At this time, the predetermined portion generates a pressure toward the outer peripheral side by the discharge of gas from the discharge device 42, and functions as a separation portion 45. Therefore, the end material 52 is detached from the predetermined location and collected into the collection box 23. The predetermined location from which the end material 52 is detached reaches the position of the suction device 41 again by rotation, and the above-described operation is repeated.

  As illustrated in FIGS. 5 and 6, the collection unit 22 includes an adsorption region 46 that adsorbs the end material 52 at the adsorption portion 44 and a non-adsorption region 47 that does not perform adsorption in the width direction D2. In the figure, the hatched portion corresponds to the suction region 46. The adsorption region 46 and the non-adsorption region 48 are formed on the outer peripheral surface of the cylindrical member 40 (that is, the outer peripheral surface 22a of the collection unit 22). In the suction region 46, the suction device 41 performs suction on the back side of the outer peripheral surface 22a, and the outer peripheral surface 22a has a plurality of fine through holes for allowing air to flow, so that suction force is generated. Yes. In the non-adsorption region 47, no suction force is generated because the suction device 41 is not provided, the suction device 41 does not operate, or no through-hole is formed in the outer peripheral surface 22a. The adsorption region 46 is formed in a region of the outer peripheral surface 22a through which the end members 52 of the rows LA and LB pass. That is, the suction region 46 is formed on both ends of the cylindrical member 40 in the width direction D2. Thereby, the outer peripheral surface 22 a sucks the end material 52 in the suction region 46. The non-adsorption region 47 is formed in the region of the outer peripheral surface 22A through which the foil body 51a of the electrodes 51 in the rows LA and LB passes. Thereby, even if the outer peripheral surface 22a contacts the foil main body 51a of the electrode 51 in the non-adsorption region 47, the outer peripheral surface 22a does not adsorb. The suction region 46 functions as a separation region in which the end material 52 is detached by discharging the gas discharged from the discharge device 42 when the separation portion 45 is reached, that is, when the position of the discharge device 42 is reached. .

  The suction region 46 is formed discontinuously along the transport direction D1. That is, a portion where the tab 51b of the electrode 51 is disposed in the region near both edges in the width direction D2 of the outer peripheral surface 22a may be set as the non-adsorption region 48. In this case, the suction region 46 corresponding to the position of the end material 52 and the non-suction region 48 corresponding to the position of the tab 51b are alternately arranged in the transport direction D1. The non-adsorption region 48 is configured by not forming a through-hole for allowing the air sucked by the suction device 41 to pass through the outer peripheral surface 22a at the corresponding location. However, in this case, the control unit (not shown) synchronizes between the cutting timing of the cutting unit 20, the conveyance position and conveyance speed of the conveyance unit 21, and the rotation position and rotation speed of the collection unit 22. It is necessary to make settings so that the tab 51b is arranged in the non-adsorption region 48 and the end material 52 is arranged in the adsorption region 46.

  Next, operations and effects of the processing apparatus 100 according to the present embodiment will be described.

  In the processing apparatus 100, when the cutting part 20 cuts the sheet member 50, the electrode 51 having a desired shape is formed, and the end material 52 is generated as an unnecessary member. Among these, the electrode 51 is attracted to the transport surface 21 a of the transport unit 21 and transported. On the other hand, the end material 52 is collected by the collection unit 22. Here, the collection unit 22 collects the end material 52 by adsorbing the end material 52 in a direction opposite to the direction in which the transport unit 21 adsorbs the electrode 51. As described above, the collection unit 22 adsorbs the end material 52 in the direction opposite to the conveyance unit 21, thereby suppressing the end material 52 from being adsorbed and conveyed to the conveyance unit 21 together with the electrode 51. By the above, the end material 52 which generate | occur | produces by cut | disconnecting the strip | belt-shaped sheet | seat member 50 can be collect | recovered suitably.

  The collection unit 22 may include an adsorption portion 44 that adsorbs the end material 52, and a separation portion 45 that separates the adsorbed end material 52 by discharging gas at a position different from the adsorption portion 44. Thereby, the collection unit 22 can detach the end material 52 that has been adsorbed and collected at the separation part 45. Therefore, the recovery unit 22 can put the recovered scrap material into the recovery box 23 and then recover a new scrap material 52.

  In the width direction D2, the recovery unit 22 may include an adsorption region 46 that adsorbs the end material 52 at the adsorption portion 44 and a non-adsorption region 47 that does not perform adsorption. With respect to the conveyed sheet member 50, a non-adsorption region 47 is disposed at a position where the electrode 51 passes, and an adsorption region 46 is disposed at a position where the end material 52 passes. Thereby, the collection | recovery part 22 can suppress adsorb | sucking the electrode 51 accidentally in the non-adsorption area | region 47, adsorb | sucking and collecting the end material 52 in the adsorption | suction area | region 46.

  The suction region 46 may be formed discontinuously along the transport direction D1. Thus, when a part of the electrode 51 extends toward the suction region 46, such as the tab 51b, the tab 51b is adjusted to be positioned in the non-suction region 48 where the suction region 46 is interrupted. Thereby, it can suppress that the electrode 51 is adsorb | sucked by the collection | recovery part 22 accidentally.

  The cutting unit 20 may cut the end material 52 as an individual member separated from the other end material 52. As described above, the end material 52 is cut as an individual member, so that the recovery unit 22 can easily recover the end material 52.

  The present invention is not limited to the embodiment described above.

  For example, in the above-described embodiment, the collection unit 22 has the non-adsorption region 48 at a position corresponding to the tab 51b. However, the non-adsorption region 48 may be omitted and used as an adsorption region. Further, in the above-described embodiment, the collection unit 22 has the adsorption region 46 and the non-adsorption region 47 in the width direction D2, and the adsorption region 46 is formed at a position that does not correspond to the foil body 51a of the electrode 51. It had been. Instead, a part of the suction region 46 of the collection unit 22 may be provided so as to reach the foil body 51a. Alternatively, the entire region in the width direction D <b> 2 of the collection unit 22 may be the suction region 46. In this case, it is necessary to adjust the adsorption force of the collection unit 22 and the adsorption force of the conveyance unit 21 so that the electrode 51 is not pulled out from the conveyance unit 21 to the collection unit 22. For example, the suction force of the transport unit 21 is made larger than that of the recovery unit 22. Conversely, a part of the suction region 36 of the transport unit 21 may be provided so as to reach the end material 52. Alternatively, the entire area in the width direction D <b> 2 of the transport unit 21 may be the suction area 36. In this case, it is necessary to adjust the suction force of the recovery unit 22 and the suction force of the transport unit 21 so that the end material 52 can be pulled out from the transport unit 21 to the recovery unit 22. For example, the suction force of the collection unit 22 is made larger than that of the transport unit 21.

  In the above-described embodiment, the recovery unit 22 includes the separation portion 45, but the separation portion 45 may be omitted. In this case, the recovery unit 22 releases the end material 52 from the recovery unit 22 by releasing the suction force.

  Moreover, although the end material 52 was comprised as an individual member isolate | separated from the other end material 52 in the above-mentioned embodiment, the end material which continues in the conveyance direction D1 may be sufficient. For example, the side edges 50a and 50b in the width direction D2 of the sheet member 50 may extend to the outside in the width direction D2 rather than the tab 51b, so that the end materials 52 may be coupled to each other in the transport direction D1. In this case, the collection unit 22 continuously collects the end material and continuously puts the end material into the recovery box 23.
