Description

  The present invention relates to an apparatus for winding and discharging a defective electrode in an electrode winding apparatus that winds a strip-shaped electrode together with a separator to manufacture a battery or a capacitor electrode.

  For example, a secondary battery is provided with a pair of positive and negative electrodes wound around a core (winding core) inside a case. The pair of electrodes are wound up by a length necessary for the core while a separator is interposed between them, and cut into one product unit.

  In the manufacturing process of each electrode, when a defect occurs in the electrode, a defect mark is attached to the defective portion by a sticky note or marking as a mark of the defective portion. For this reason, when a defective mark is detected in the electrode winding process, the defective portion of the electrode corresponding to the defective mark must be discharged as a defective electrode so as not to enter the product.

  The winding of the defective electrode can be realized by using the product winding mechanism of the electrode winding device. However, if the product take-up mechanism is used for discharging defective electrodes, the product take-up mechanism may be contaminated, which may hinder normal electrode take-up. A dedicated device is preferably provided in the electrode winding device.

  Patent Document 1 discloses a general electrode winding device and a technique for attaching a tab (defective mark).

Japanese Patent Laid-Open No. 2002-198084

  An object of the present invention is to enable an electrode winding apparatus to wind up and discharge a defective portion of an electrode alone as a defective electrode when a defective mark is detected.

Based on the above problems, the present invention is a process of winding a pair of electrodes, a separator interposed between the pair of electrodes around the outer periphery of the core, the electrode from the upstream in the electrode movement direction, a defect detector, an electrode clamp, A defect is supplied to the core via the electrode cutter, and a defective electrode take-up device is provided between the electrode cutter and the core so as to be able to advance and retract. When the defect detector detects the defect mark on the electrode, the defect corresponds to the defect mark. In an electrode winding device that winds an electrode with the defective electrode winding device and separates and discharges the defective electrode from the subsequent electrode by a cutting operation of the electrode cutter, the defective electrode winding device is A pair of openable and closable chucks for operation, an operation drive unit for opening and closing the chuck, a rotation drive unit for rotating the chuck, and a chuck in a standby position Are constituted by a reciprocating drive means for reciprocating between a work position (claim 1).

In particular, the present invention relates to a slide guide means for reciprocating the chuck between the standby position and the operating position, a slide guide actuator for driving the slide guide means, and a slide guide means. And a tilt mechanism for rotating the chuck (claim 1).

And, when the defective electrode is discharged, the present invention moves the chuck from the standby position to the operating position by the reciprocating driving means, and closes the defective electrode by closing the chuck by the operation driving unit at the operating position, The chuck is rotated by the rotation driving unit to wind the defective electrode around the chuck, and the tilt mechanism is used to rotate the chuck and set the chuck in the downward direction. It is characterized by being dropped by gravity from the chuck and discharged (Claim 1).

According to the present invention, in the above-described defective electrode winding device, the pair of chucks are opened and closed by a displacement in a contact / separation direction (claim 2 ).

  In the present invention, for each electrode of the electrode winding device, a dedicated defective electrode winding device is provided between the electrode cutter and the core so as to be reciprocally movable (movable back and forth) between the standby position and the chucking position. Therefore, the normal electrode winding operation is not hindered by the presence of the defective electrode winding device at the standby position, and when the defective electrode is wound, the chuck clamps the defective electrode and then rotates. Since the defective electrode is wound, the defective electrode can be wound even in a narrow space, and the defective electrode after winding can be separated and discharged from the subsequent electrode by the cutting operation of the electrode cutter for cutting one product length, Furthermore, since the winding length of the defective electrode can be appropriately set according to the amount of rotation of the chuck, that is, the amount of winding around the outer periphery of the chuck, the electrode is not wasted. Claim 1).

In particular, when the reciprocating drive means reciprocates the chuck between a standby position and an operating position and discharges the defective electrode wound up at the operating position, the reciprocating drive means causes the chuck to move downward by rotating the tilt mechanism. The defective electrode wound up is dropped from the chuck by gravity (Claim 1).

Therefore, when the tilt mechanism is built into the reciprocating drive means, by the downward direction of the setting of the chuck, because poor electrode of the chuck in a state to fall naturally from the chuck by gravity, poor electrode to the discharge of the defective electrode This eliminates the need for a special discharging mechanism such as a sampling means , and is advantageous (claim 1 ).

When the pair of chucks to the form to be opened and closed by the displacement of the contact and separation direction, it is easy gripping and release of defective electrode can be realized by also a simple configuration that opening and closing operation (claim 2).

  1 and FIG. 2 show a strip-like electrode 2 on the side of a positive electrode, a negative electrode 3, and a pair of insulating electrodes 2 and 3 interposed between the pair of electrodes 2 and 3 in the electrode winding device 1 as a premise of the present invention. The separators 4 and 5 are fed out from the reels 6, 7, 8, and 9, respectively, and are guided to the pair of nip rollers 10 by a plurality of guide rollers 11, 12, 13, 14, a dancer roller (not shown), and the like as necessary. Then, it is wound around the outer periphery of the core 38 through a pair of nip rollers 10.

  The pair of nip rollers 10 are provided as necessary near the product winding position S, but at least one of them is capable of contacting and separating from the other.

  The electrodes 2 and 3 are located upstream of the position of the pair of nip rollers 10 in the direction of electrode movement, between the electrode clamps 23 and 24, between the pair of electrode cutters 25 and 26, and the defective electrode winding device of the present invention. It passes between 31 and 32 and reaches between the pair of nip rollers 10.

  The pair of electrode cutters 25 and 26 is, for example, a shearing type with an operation actuator, and is provided for cutting each electrode 2 and 3 into a predetermined length for each product, that is, one product length L. In addition, the electrode clamps 23 and 24 hold the subsequent cutting-side tips of the electrodes 2 and 3 cut by the electrode cutters 25 and 26, respectively, and move to the positions of the pair of nip rollers 10 so that each electrode 2 , 3 as the respective winding start ends P are guided to positions where they can be wound between the pair of nip rollers 10.

Defective electrode winding apparatus 31 and 32 are provided for each of the electrodes 2 and 3, failure of the electrodes 2 and 3 corresponding to the defective marks 15, 16 by tag or markings that are previously attached to the electrodes 2 and 3 In order to wind up the portion as a defective electrode and discharge the wound defective electrode, the pair of electrode cutters 25 and 26 and the pair of nip rollers 10 can freely move forward and backward in the direction perpendicular to the paper surface of FIGS. Is provided.

  3 and 4 show the configuration of the defective electrode take-up device 31. FIG. In addition, since the defective electrode winding device 31 and the defective electrode winding device 32 have the same configuration, the following description describes only one defective electrode winding device 31 and the other defective electrode winding device 32. The description about is omitted.

  3 and 4, the defective electrode winding device 31 includes a pair of openable and closable chucks 33 for winding the defective electrode, an operation driving unit 39 that opens and closes the chuck 33, and a rotational driving unit that rotates the chuck 33. 40 and reciprocating drive means 41 for reciprocating the chuck 33 between the standby position and the operating position. The pair of chucks 33 are opened and closed by displacement in the contact / separation direction.

  The reciprocating drive means 41 specifically includes a linear rail 47 and a slider 48 attached to the frame 45 as slide guide means 42 for reciprocating the chuck 33 between the standby position and the operating position, and the slider 48. The actuator includes a slide guide actuator 49 such as a motor to be driven, and a winding conduction means 50 such as a chain sprocket that transmits the rotation of the actuator 49 to the slider 48.

  Further, the defective portion of the electrode 2 taken up by the chuck 33, that is, the defective electrode is extracted from the outer periphery of the chuck 33 by the joint operation of the reciprocating drive means 41 and the extraction means 44. For this extraction operation, the extraction means 44 includes a cylinder 51 attached to the frame 45 between the standby position and the operation position of the chuck 33, and a bifurcated stopper 46 attached to the piston rod 52 of the cylinder 51. It consists of The stopper 46 forms a U-shaped slit 46a having a size for sandwiching the core 38 at the forked portion.

  As shown in FIG. 4, the defective electrode winding device 31 is positioned inside the frame 45 so as to move back to the standby position when not in operation and not interfere with the normal winding operation of the electrodes 2 and 3. However, as shown in FIG. 3, during operation, that is, when a defective portion of the electrode 2 is wound up, it advances from the standby position to the operation position, approaches the electrode 2, and a corresponding electrode 2 is taken up by a pair of defective electrode winding chucks 33. And the defective portion of the electrode 2 is wound up on the outer peripheral surface of the chuck 33 by the rotation of each chuck shaft 29.

  Returning to FIG. 1, the defect marks 15 and 16 are detected by defect detectors 17 and 18, respectively. As shown in FIG. 5, the defect detectors 17 and 18 have one product length L or more, preferably two product lengths at the upstream position in the electrode movement direction from the product winding position S for each of the electrodes 2 and 3. It is installed in 2 × L.

  The above-mentioned 1 product length L and 2 product length 2 × L are distances from the product winding position S on the electrode winding device 1, and the electrodes are cut from the cutting positions (cut ends) by the electrode cutters 25 and 26. This corresponds to the upstream distance along the lines 2 and 3.

As will be described later, after the electrodes 2 and 3 are cut at the cutting positions by the corresponding electrode cutters 25 and 26, the upstream cut ends of the electrodes 2 and 3 in the electrode moving direction are guided to the product winding position S. The At that time, the winding start end P of each of the electrodes 2 and 3 coincides with the product winding position S and appears for each product length L on the upstream side in the electrode movement direction.

  The winding length of the electrodes 2 and 3 by the respective defective electrode winding devices 31 and 32 preferably corresponds to the defective marks 15 and 16 from the winding start end P for one product in which the defective marks 15 and 16 are detected. The length (L1 + α) obtained by adding a predetermined margin length α to the length L1 up to the position is set so that the defective portion of the electrodes 2 and 3 is included in the length (L1 + α), or the length Instead of (L1 + α), one product length L is set from the winding start end P of the electrodes 2 and 3 for one product in which the defect marks 15 and 16 are detected, and the electrodes 2 and 3 are included in the length L. Set to include the defective part.

  The length L1 from the winding start end P for one product to the position corresponding to the defective marks 15 and 16 is measured by the length measuring devices 19 and 20 for the electrodes 2 and 3, respectively. As shown in FIGS. 1 and 3, the length measuring devices 19 and 20 have length measuring rollers 21 and 22, respectively, and are installed in accordance with the installation positions of the defect detectors 17 and 18, as shown. Although not shown in the figure, the defect detectors 17 and 18 are installed at an appropriate distance on the upstream side in the electrode movement direction. Each length measuring roller 21, 22 is in rolling contact with the corresponding electrode 2, 3 and rotates according to the movement of the electrode 2, 3.

  The length measuring devices 19 and 20 integrate the rotation of the length measuring rollers 21 and 22, and during the winding operation of the normal electrodes 2 and 3 that have been wound earlier, or defective portions of the electrodes 2 and 3 When the detection signals of the defect marks 15 and 16 are received from the defect detectors 17 and 18 with respect to the electrodes 2 and 3 of one product length L to be wound next, the next winding is performed. The length L1 from the winding start end P of the electrodes 2 and 3 to the position corresponding to the defective marks 15 and 16 is measured from the rotation amount (number of rotations) of the length measuring rollers 21 and 22, and the subsequent electrodes In preparation for winding up the second and third defective portions, the length L1 is stored, and the margin length α is added to the length L1, or the length (L1 + α) is directly set at the position corresponding to the length (L1 + α). L1 + α) to measure defective parts of the electrodes 2 and 3 Determining the required length (L1 + alpha) on the discharge of.

  The normal electrodes 2 and 3 are wound around the outer periphery of the cylindrical core 38 at the product winding position S, that is, the position of the winding station, through the nip roller 10 together with the separators 4 and 5. The core 38 is inserted into the split type winding core 37 as an example, and rotates together with the winding core 37 and the rotating shaft 36 integral therewith during the winding operation. The rotating shaft 36 is connected to a drive motor (not shown) so that each product can rotate as many times as necessary for winding.

  The split-type winding core 37 has a large outer peripheral length when it is displaced in the diameter direction of the rotary shaft 36, and keeps the core 38 from slipping out, but the electrodes 2 and 3, the separator 4. , 5 after being wound, the outer peripheral length is reduced by displacing it to the position where it completely overlaps, and the electrodes 2, 3 and the separators 4, 5 wound around the outer periphery of the core 38 are removed. Make it easy to remove. For this reason, although a displacement operating means is attached to the winding core 37, they are incorporated in the rotary shaft 36, although not shown.

  The electrode winding device 1 is controlled by the program of the control device 35, and performs normal winding operations of the electrodes 2, 3 and the separators 4, 5 in the following order. First, the separators 4 and 5 are guided in advance so as to pass between the pair of nip rollers 10, and are fixed in an overlapped state on the outer peripheral surface of the core 38 by means of welding or the like at their tip portions.

  On the other hand, the electrode clamp 23 moves forward while holding the tip of the electrode 2 on the positive electrode side, and moves backward after being brought between the pair of separated nip rollers 10. Similarly, the electrode clamp 24 moves forward while holding the tip of the electrode 3 on the negative electrode side, and then moves back between the pair of nip rollers 10 that are separated from each other.

Here, the pair of nip rollers 10 approach each other to sandwich the electrodes 2 and 3 and the separators 4 and 5, and then maintain a predetermined pressure contact force to sandwich them. In this state, since the electrodes 2 and 3 pass in front of the defective electrode take-up devices 31 and 32 in the standby position, the defective electrode take-up devices 31 and 32 are obstructed by movement of the respective electrodes 2 and 3. Don't be.

  According to the illustrated example, the core 38 rotates counterclockwise together with the winding core 37, so that the electrodes 2 and 3 are stacked in a clockwise direction with respect to the core 38. Due to this laminated winding, the pair of electrodes 2 and 3 and the separators 4 and 5 are arranged in the order of the electrode 2, the separator 4, the electrode 3 and the separator 5 from the right side to the left side in the drawing between the pair of nip rollers 10. So that the core 38 can be wound up as a laminated state in the clockwise direction.

  Next, the winding core 37 is driven counterclockwise by being driven by a drive motor and a rotating shaft 36 (not shown), and the electrode 2, the separator 4, the electrode 3, and the separator 5 are sequentially stacked on the outer peripheral surface of the core 38. The number of windings corresponding to one product length L is wound and stopped. At this time, the electrode cutters 25 and 26 sequentially cut the electrodes 2 and 3 held by the electrode clamps 23 and 24 to prepare for the next winding operation.

  Thereafter, the split-type winding core 37 is displaced in the direction of reduction in the outer peripheral length, so that the core 38 and the electrodes 2 and 3 and the separators 4 and 5 wound around the outer periphery are removed from the winding core 37. A take-out device (not shown) takes out the core 38, the electrodes 2 and 3 wound around the outer periphery thereof, and the separators 4 and 5 from the take-up core 37 as a unit.

  After this removal, the separators 4 and 5 are cut from the core 38. The end portion on the winding end side at this time is wound around the outer periphery of the electrodes 2 and 3 and the separators 4 and 5 wound around the outer periphery of the core 38, and the winding start end P is used for the next winding operation. It is fixed to the outer periphery of the next core 38 attached to the winding core 37 by welding or the like. In this way, following the previous electrodes 2 and 3, the winding operation for the next electrode 2 and 3 having one product length L is started.

  The normal winding operation is controlled by the control program of the control device 35. The control device 35 also has a built-in program for winding the defective portions of the electrodes 2 and 3 as defective electrodes. In the middle of the control program for the normal winding operation, the defective electrode is wound.

  As already described, when the electrodes 2 and 3 are defective in coating in the manufacturing stage of the electrodes 2 and 3, defective marks 15 and 16 are attached to the positions. When defective marks 15 and 16 are detected by the defect detectors 17 and 18 in the winding operation process, defective portions of the electrodes 2 and 3 are wound by the defective electrode winding devices 31 and 32 of the present invention. It is discharged as follows. Since the operations of the electrodes 2 and 3 are the same, the following description is given only for one of them as necessary.

  FIG. 6 shows a flowchart when the winding of the defective electrode is executed by the program of the control device 35 in the electrode winding process. In the first step S1 after the start, the defective electrode winding program confirms the end of normal winding of one product for the electrodes 2 and 3 or the winding and discharging end of the defective portion of the electrodes 2 and 3. In the subsequent step S2, is the defect mark 15, 16 detected by the defect detector 17, 18 on either the positive or negative electrode 2, 3 during the next product length L? Make a decision.

  When the defect mark 15 is detected in any of the electrodes 2 and 3, for example, the electrode 2 in step S <b> 2 and the answer is YES, the program reads the electrode 2 in which the defect mark 15 is detected in step S <b> 3. In step S4, during the winding of the defective portion of the electrode 2, a defective mark 15 is detected for the next electrode 2 of the next product length L in step S4. Exit and return to the start.

  The winding and discharging of the defective portion of the electrode 2 in the above step S3 is performed as follows. The defective electrode take-up device 31 corresponding to the electrode 2 advances from the standby position to the operating position of FIG. 3 by the operation of the reciprocating drive means 41 and approaches the moving path of the electrode 2. At this time, as shown in FIG. 2, the operation driving unit 39 stands by in a state in which the defective electrode winding chuck 33 is released. Here, the electrode clamp 23 guides the cut end of the electrode 2 cut by the electrode cutter 25 between the chucks 33 after the winding of the previously wound electrode 2 is completed.

  Next, the defective electrode winding device 31 operates the operation driving unit 39 to sandwich the electrode 2 between the pair of chucks 33, and then operates the rotation driving unit 40 to rotate the chuck shaft 29. The defective portion of the electrode 2 is wound around the outer periphery of the chuck 33 as a defective electrode. The winding length at this time can be set by the number of rotations of the chuck 33.

  As described above, when the length measuring device 19 is installed, the winding length of the electrode 2 is the length (L1 + α) obtained by adding the margin length α (constant) to the measured length L1. However, when the length measuring device 19 is not installed, the winding length of the electrode 2 is one product length from the winding start end P of the electrode 2 for one product in which the defect mark 15 is detected. Let L be.

  After the winding operation, the electrode cutter 25 cuts the electrode 2 at that position, and separates the electrode 2 taken up by the rotation of the chuck 33 and the subsequent electrode 2. After the separation, the defective electrode take-up device 31 is moved back to the standby position in FIG. 4 by the operation of the reciprocating drive means 41 so that the wound electrode 2 including the defective portion can be discharged.

  The electrode 2 including the defective portion wound around the pair of chucks 33 is in a state where it can be removed from the chuck 33 manually or by an automatic take-out device.

  According to the specific example of FIGS. 3 and 4, since the extraction means 44 is provided, the extraction means 44 moves the bifurcated stop bar 46 while the pair of chucks 33 moves to the standby position of FIG. 4. Lowering, sandwiching the core 38 with the slit 46a, and blocking the passage of the defective electrode wound around the core 38, the defective electrode is pushed out in the extraction direction by the extracting means 44, and the defective electrode wound up from the chuck 33 is extracted, It is discharged into the collection box 53. As described above, the extracting means 44 extracts and discharges the defective electrode wound around the core 38 by using the movement of the chuck 33.

  After discharging the electrode 2 including the defective portion, the electrode clamp 23 brings the winding start end P of the succeeding normal electrode 2 between the pair of nip rollers 10 and then moves backward to take up the normal electrode 2. Make it ready to resume. These operations are the same for the electrode 3.

  On the other hand, when the defect marks 15 and 16 are not detected in any of the electrodes 2 and 3 in the above step S2, and the determination is NO, the program in the next step S5, the next one product length L electrode The normal winding process of one product length L for 2 and 3 is executed, and in the normal winding of the current one product length L in step S6, the subsequent one product length L The defective marks 15 and 16 are detected for the electrodes 2 and 3, and the process returns to the start.

  As a result of this operation, after the defective portions of the electrodes 2 and 3 are wound up, the defective portions are separated and discharged, the defective marks 15 and 16 are not detected on the respective electrodes within the next one product length L. In this case, the winding start end P of the electrodes 2 and 3 is guided to the product winding position S, and normal winding of the electrodes 2 and 3 is started.

Next, FIGS. 7 and 8 show a concrete poor electrode winding apparatus 31 as an example of a defective electrode winding apparatus 31 and 32 of the present invention. Defective electrode winding apparatus 31 includes a defective electrode take-up of the chuck 33, a tilt mechanism 54 for rotating slider 48 on the slide guide means 42 the operation driver 39 and the rotary drive unit 40. The tilt mechanism 54 has a rotary actuator 43 on the slider 48. The tilt shaft 55 is rotated by the rotary actuator 43 in a range of about 90 degrees, the chuck 33 is set downward, and is wound around the outer periphery of the chuck 33. utilizing the taking electrode 2 gravity to drop the defective electrode wound from the chuck 33, it is discharged into the collection box 53.

  Although it is assumed that the defective electrode winding devices 31 and 32 of the present invention are attached to each of the electrodes 2 and 3 of the electrode winding device 1, the electrode winding device 1 has the configuration shown in FIGS. Not exclusively.
