Description

  The present invention relates to a method for removing a winding covering tape that removes a covering tape peeled off and wound around a reel body while moving a carrier tape covered with a peelable covering tape, and a reel body of a component supply device In addition, the present invention relates to a component supply device.

  In recent years, in an electronic circuit board assembly process, an electronic component mounting apparatus for automatically mounting a chip-type electronic component or the like on a substrate has become indispensable. Some of these electronic component mounting apparatuses include a component supply device that supplies electronic components using a carrier tape. This component supply device makes it possible to take out an electronic component stored in a storage portion of the carrier tape while peeling the covering tape covering the carrier tape, and supplies the electronic component to the electronic component mounting device.

  By the way, in recent years, with the improvement of the productivity of the electronic component mounting machine, the replacement work of the carrier tape of the component supply apparatus is performed at short intervals. For this reason, in the prior art, a carrier tape having an electronic component storage part and covered with a peelable covering tape is transported along the transport surface, and the covering tape is wound around the reel body while being peeled from the carrier tape. In the component supply apparatus that enables the electronic component to be taken out from the storage unit, the winding surface of the reel body is formed in a shape that is inclined toward the guide flange provided on one end surface of the winding drum, and the covering tape is guided to the reel body A technique for winding along the flange side is disclosed (see, for example, Patent Document 1).

  By adopting such a configuration, the coated tape is always wound stably on the reel body side, the reel body is easily removed, and the rotational resistance of the take-up ratchet is reduced. A component supply device that prevents deformation of the take-up ratchet and does not cause winding failure is provided, and the supply rate and productivity of electronic components are improved.

  In another prior art, the tape is separated from the storage tape in the middle of this movement while moving the taping component that is stored in the longitudinal direction of the storage tape at a predetermined pitch and covered with the coating tape. In a component supply apparatus that sequentially supplies components to a predetermined position, a reel for winding the separated covering tape has a winding drum that is detachably attached to the drive shaft and a guide flange at one end of the drum A reel body is provided, and an auxiliary ring made of an inelastic body is fitted on the outer periphery of the reel body of the reel body so as to be detachably fitted with a non-rotating engagement portion, and the covering tape is wound around the outer periphery of the auxiliary ring. Have been disclosed (for example, Patent Document 2). In addition, an appropriate number of jig through holes are provided substantially at the position of the outer periphery of the winding drum of the guide flange portion of the reel body.

By adopting such a configuration, when the auxiliary ring fitted to the winding drum is removed together with the covering tape wound around the auxiliary ring, the auxiliary ring is a non-elastic body and fits with the winding drum even by the winding pressure. It is not too tight and can be easily removed from the drum. Further, since the removed auxiliary ring does not have a hindrance like a guide flange around it, and a separating force can be applied from various places around it, the covering tape can be easily and quickly removed. Further, since the guide flange is provided with the jig through hole, the auxiliary ring can be easily and quickly removed from the winding drum by the jig inserted through the jig through hole. As a result, it is possible to replace the supply parts in a short time by attaching the reel body to the drive shaft again.

  However, since the winding of the coated tape by the reel body is performed while peeling the coated tape from the carrier tape, peeling resistance works, and the coated tape is often wound relatively tightly around the reel body of the reel body. . For this reason, when parts replacement of the parts supply device occurs, when removing the wound covering tape from the winding drum, the covering tape must be unwound from the winding drum, and the covering tape cannot be easily detached from the winding drum. However, it takes time and effort, and during this time, the supply of parts is stopped, and the supply rate and productivity of electronic parts may be reduced. Further, even in a component supply apparatus having an auxiliary ring and a jig through hole, if the covering tape is wound tightly around the auxiliary ring, the covering tape cannot be easily detached from the auxiliary ring.

  The present invention has been made in view of the above situation, and it is possible to remove a wound coating tape that can be easily, quickly and surely removed without using a jig. It is an object of the present invention to provide a reel body of a method and a component supply device, and a component supply device, thereby improving the supply rate and productivity of electronic components.

  The present invention achieves the above-described object by forming the ring so that it can be bent in the plane of the ring, and specifically includes the following contents.

  That is, the first aspect of the present invention includes a take-up reel that is intermittently driven by a component supply device, a take-up cap that is detachably attached to the take-up reel, and a space between the take-up reel and the take-up cap. A component supply device configured to wind up and collect a covering tape that covers and protects a carrier tape that supplies a component to a component mounting apparatus after use on a winding surface that is an outer peripheral surface of the ring It is related with the winding part of the components supply apparatus, Comprising: The said ring is comprised so that bending in the plane of the said ring is possible.

  The ring can be configured to be fitted to either the boss portion of the take-up reel or the winding drum of the take-up cap.

  The said ring can be comprised from a pair of semicircle-shaped member and a pair of connector which couple | bonds both members so that bending is possible. The semicircular member may be formed by sheet metal processing. The pair of semicircular members can be common parts.

  Another aspect of the present invention is a component supply device that transports a carrier tape containing a component and supplies the component to a component mounting apparatus, and collects the covering tape that covers and protects the carrier tape after use. The present invention relates to a component supply device including the winding unit according to any one of the above.

  Still another aspect according to the present invention is a covering tape recovery method for winding and recovering a covering tape that covers a carrier tape that supplies a component to a component mounting apparatus, and then winding the covering tape around the outer peripheral surface of the ring. The present invention relates to a method for recovering a coated tape, wherein the coated tape is recovered by releasing the tensile force of the wound coated tape by bending it in the plane of the ring.

  As a result of implementing a foldable ring for winding the coated tape according to the present invention, it is possible to bend the ring in a state in which the coated tape is wound and to eliminate the squeezing force by the wound coated tape. The covering tape can be easily removed. For this reason, the setup of the reel body can be completed in a short time, and the productivity of component mounting can be improved.

  BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of a method for removing a winding covering tape according to the present invention, a ring that can be fitted to a take-up reel or a take-up cap of a component supply device, and a component supply device will be described in detail below with reference to the drawings. Explained. FIG. 1 is a perspective view of a component supply apparatus according to the present embodiment. In the figure, a component supply apparatus 100 is applied to an electronic component mounting apparatus (not shown) that mounts an electronic component on a printed circuit board or the like, and the number of types of electronic components required by the mounting apparatus is included in this mounting apparatus. The component supply device 100 that is equipped with the supply device 100 and holds electronic components of a necessary type from time to time is moved to a position facing the mounting device. Then, the electronic component supplied to the component supply position is sucked by the suction nozzle disposed in the component mounting head of the mounting apparatus and mounted on the printed board or the like.

  In general, the component supply apparatus 100 receives a command (pressing operation) from the electronic component mounting apparatus side and has a main body 1 having a component supply section that supplies an electronic component, and a taping component wound around the main body 1. And a component reel holding portion 3 for holding the reel. The carrier tape 5 wound and held on the component reel holding unit 3 is configured by storing electronic components in a storage unit (not shown) formed at a predetermined pitch in the longitudinal direction and covering the upper surface with a covering tape 7.

  Further, the main body 1 includes a covering tape winding unit 9 and a component supply unit 11, and a driving force transmission unit that overlaps the covering tape winding unit 9, the component supply unit 11, and some components for driving each of them. 13.

  The covering tape take-up portion 9 is fixed to the frame 15, and receives a pressing operation from the electronic component mounting apparatus and rotates about the fulcrum shaft 17. It has a letter shape, has a protrusion 23a inserted into the opening 19a of the feed lever 19 on one end side, and the protrusion 23a comes into contact with the inner wall surface of the opening 19a as the feed lever 19 rotates. A rotating take-up lever 23, a gear arm 25 attached to a support shaft (not shown) formed on the other end side of the take-up lever 23 via a biasing spring (not shown), and a support shaft (not shown) at the tip of the gear arm 25 It is attached to the main body 1 through a winding gear 27 having a pivotally supported one-way clutch and a one-way clutch 29a (see FIG. 2) that is allowed to rotate only in the winding direction. Lighted peripheral surface and a take-up reel 29 for formed tooth profile.

  The winding gear 27 meshes with teeth on the circumferential surface of the take-up reel 29 and is allowed to rotate only in the direction opposite to the direction in which the take-up reel 29 can rotate. That is, in a state where the winding gear 27 and the take-up reel 29 are engaged with each other, the rotation is allowed only in the take-up direction of the take-up reel 29. A take-up cap 31 is attached to the take-up reel 29 so as to face the take-up reel 29, and the covering tape 7 is wound around the take-up reel 29 and the take-up cap 31.

  The feed lever 19 is always urged upward in FIG. 1 by the feed spring 33, and the take-up lever 23 is always urged upward in FIG. 1 by the take-up spring 35 fixed to the frame 15 side. The gear arm 25 presses the winding gear 27 against the peripheral surface of the take-up reel 29 by a biasing spring (not shown). Further, tension rollers 37 and 39 for suspending the covering tape 7 are rotatably disposed on the frame 15, and a charge roller 41 is rotatably disposed at the end of the feed lever 19. The covering tape 7 is suspended from the tension rollers 37 and 39 after being peeled off from the carrier tape 5, wound around the take-up reel 29, and pulled up from the charge roller 41 between the tension rollers 37 and 39 in FIG.

  In the covering tape winding unit 9 configured as described above, the pressing surface 19b at the tip of the feed lever 19 receives the pressing operation from the electronic component mounting device from the initial state where the feed lever 19 is not pressed, and the feed lever 19 Swings. When the feed lever 19 swings, the take-up lever 23 is rotated by the pulling force of the take-up spring 35 so that the protrusion 23a is along the inner wall of the opening 19a of the feed lever 19. Then, the take-up reel 29 is rotated in the take-up direction with the hoisting gear 27 attached to the tip of the gear arm 25 stopped rotating.

  When the pressing operation is released and the feed lever 19 returns to the initial state due to the elasticity of the feed spring 33, the projection 23a of the take-up lever 23 comes into contact with the inner wall surface of the opening 19a of the feed lever 19, and the take-up lever 23 is pulled back. Then, the winding gear 27 meshes with the teeth of the take-up reel 29 while rotating and returns to the initial position. At this time, since the take-up reel 29 is prevented from rotating in the direction opposite to the take-up direction by the one-way clutch 29a, the take-up reel 29 stops in a state where the covering tape 7 is taken up without rotating.

  The component supply unit 11 includes a shutter (not shown) supported so as to be slidable, and the shutter receives a force from the driving force transmission unit 13 and slides. Further, the shutter has a slit 43, and is formed so that the upper surface of the storage portion of the carrier tape 5 is narrowly opened and the upper surfaces on both ends in the covering tape width direction are widened. The covering tape 7 is peeled off by the shutter at a guide portion (not shown) that holds the upper surface of the carrier tape 5.

  Next, the covering tape winding unit 9 will be described. FIG. 2 shows a cross section of the covering tape winding portion 9 according to the present embodiment. In the figure, in the present embodiment, the covering tape 7 peeled off from the carrier tape 5 is wound on a winding surface 51 a that is an outer peripheral surface of a ring 51 fitted to the boss portion 61 of the winding reel 29. . The take-up reel 29 is fixed to the drive shaft 47. As will be described later, the take-up cap 31 is detachably attached to the drive shaft 47 via the take-up reel 29.

  A pair of locking wings 63, 63 are provided on the left end surface of the take-up reel 29 in the drawing. Further, a pair of locking grooves 65, 65 cut out radially outward of the winding cap 31 is formed. The take-up cap 31 is detachably attached to the take-up reel 29 by inserting the lock wings 63 and 63 into the lock grooves 65 and 65 and rotating the take-up cap 31 relative to the take-up reel 29. In this way, the covering tape 7 is wound around the winding surface 51 a of the ring 51 held between the winding reel 29 and the winding cap 31 and fitted to the boss portion 61 of the winding reel 29, and collected. Is done.

  3A to 3C show details of the ring 51 according to the present embodiment. In each figure, the ring 51 is composed of first and second ring halves 52 and 54 each formed in a semicircular shape, and a pair of connectors 58 that fix both the ring halves 52 and 54 so that they can be bent. ing. The bending at this time is bending in the plane in which the ring 51 is formed (the direction in which both ring halves overlap). As the connector 58, for example, a screw-type screw or a caulking-type pin can be used. A hinge portion 56 is provided at each end of the ring 51 and the half halves 52, 54, and is fixed by a connector 58 so as to be foldable through a through hole in this portion. By configuring both ring halves 52 and 54 in this way, both halves can be used as a common part. A winding surface 51 a is formed on the outer periphery of the ring 51.

  Each of the ring halves 52 and 54 can be manufactured from sheet metal by pressing. Alternatively, it may be formed by machining. When the ring 51 is fitted to the boss portion 61 of the take-up reel 29, the hinge portion 56 protrudes inward and interferes. In order to avoid this, the boss portion 61 is provided with a relief. Since the leading end of the covering tape 7 to be wound is inserted and fixed in a slit provided in the take-up reel 29, it is not necessary to apply a rotational driving force to the ring 51 itself.

  The ring 51 is fitted to the boss 61 of the take-up reel 29 in a perfect circle state as shown in FIGS. 3A and 3B, and a certain amount of the covering tape 7 is wound on the take-up surface 51a. Taken. FIG. 4 shows a cross section of the ring 51 in which the covering tape 7 is wound on the winding surface 51a. Thereafter, the detachable take-up cap 31 is removed, and the ring 51 in the state shown in FIG. 4 is pulled out from the boss portion 61, and as shown in FIG. It can be folded into a huge shape. The tensile force due to winding applied to the covering tape 7 by this bending is eliminated, and the covering tape 7 can be easily recovered from the winding surface 51a.

  FIG. 5 shows an alternative embodiment of the covering tape winding portion 9 shown in FIG. In the drawing, the ring 51 is fitted and attached to a winding drum 59 which is a boss provided on the winding cap 31 side, not on the winding reel 29 side. Other configurations are the same as those shown in FIG. Even in such a configuration, the covering tape 7 is wound around the winding surface 51 a of the ring 51, and then the ring 51 is pulled out from the winding drum 59 and bent around the hinge portion 56, as in the previous embodiment. Thus, the covering tape 7 can be easily recovered. According to this aspect, when the take-up cap 31 is removed from the take-up reel 29, the ring 51 is removed together with the take-up cap 31 while being fitted to the wind drum 59.

  Although not shown in the drawing, the winding drum 59 or the boss portion 61 can be either one of them, or can be divided into 1: 1 or non-uniformly, for example. It is possible to select the best workability according to the type of apparatus.
