Yes. Further, holes (or notches) 86, 85, 87 are alternately formed in the wall 83b and the wall 83c. Furthermore, as shown in the figure, a convex portion 88 is formed on the inner surface of the wall portion 83b facing the space on the back side (wall portion 83a side) of the insertion hole 84. As shown in FIG. 11, the inner surface 85a on the door body 82 side that forms the insertion hole 84 is formed at a substantially right angle with respect to the end surface 83d, and the inner surface 85b opposite to the inner surface 85a has a predetermined value with respect to the end surface 83d. It is formed on a slope inclined at an angle (for example, 60 degrees). Therefore, each inner surface 85a, 85b is formed so that a mutual space | interval may become narrow gradually as it goes to the back | inner side (wall part 83a side) of the insertion hole 84. FIG.

  On the other hand, the spring member 91 attached to the door member 81 is constituted by a torsion coil spring (torsion spring) having coil portions 91a and 91a and arm portions 91b and 91c, as shown in FIG. The tip 91d of the arm portion 91b is folded back and formed in a P-shape in substantially the same plane as the coil portions 91a and 91a (on the paper surface). Furthermore, the distal end portion 91e of the arm portion 91c is folded back in a plane substantially orthogonal to the coil portions 91a and 91a to form a P shape. In this case, the spring member 91 is brought into contact with a stopper formed on the inner side wall of the case body in the cartridge case, and the tip 91d is mounted on the spring mounting portion 83 of the door member 81. The door member 81 is urged toward the direction of closing the tape outlet.

  On the other hand, the applicant has developed an assembly apparatus for assembling the slide door 73 shown in FIG. 9 using the door member 81 and the member 91. This assembling apparatus includes, for example, a holding jig that holds the door member 81 and a moving mechanism that holds the spring member 91 and inserts the distal end portion 91 d into the insertion hole 84 of the door member 81. When assembling the slide door 73 using this assembling apparatus, the door member 81 is set (held) on the holding jig with the insertion hole 84 facing upward. Next, the moving mechanism grips, for example, the coil portions 91a and 91a of the spring member 91, and moves the spring member 91 from the diagonally upper side of the door member 81 held by the holding jig toward the insertion hole 84. To insert the distal end portion 91d into the insertion hole 84. In this case, after moving the spring member 91, the moving mechanism adjusts the angle so that the arm portion 91b of the spring member 91 is inclined at a predetermined angle (in this case, 60 degrees with respect to the horizontal direction). Next, the moving mechanism moves the spring member 91 to a position where the distal end portion 91d of the spring member 91 contacts the wall portion 83a of the door member 81 (inserts the distal end portion 91d). At this time, at least one of the distal end portion 91d and the convex portion 88 is elastically deformed, so that the convex portion 88 enters the inner peripheral side of the distal end portion 91d folded back into a P shape, and the distal end portion 91d and the convex portion 88 are inserted. And engage. Thereby, the attachment of the distal end portion 91d of the spring member 91 to the spring mounting portion 83 is completed, and the slide door 73 is assembled.

As shown in the figure, the posture changing mechanism 3 includes a main body portion 31 and a contact plate (contact portion in the present invention) 32. In this case, the posture changing mechanism 3 contacts the contact plate 32 on the upper side of the spring member 91 held by the holding jig 63 at the posture changing position P2 on the transport mechanism 6 as shown in FIG. The posture of the spring member 91 is changed to the assembly posture at the time of assembly by pushing down to a predetermined position.

  As shown in FIG. 2, the assembly mechanism 4 includes a main body portion 41 and a holding portion 42. In this case, the assembly mechanism 4 holds and moves the door member 81 supplied from the parts feeder (not shown) and transported by the transport track 43, and at the assembly position P3 on the transport mechanism 6, as shown in FIG. The slide door 73 is assembled by inserting the distal end portion 91 d of the spring member 91 held by the holding jig 63 into the insertion hole 84 of the door member 81 and connecting the spring member 91 and the door member 81. Further, after assembling the slide door 73, the assembly mechanism 4 causes the holding portion 42 to release the holding of the door member 81 and then move it upward to move it to the original position. As shown in FIG. 2, the take-out mechanism 5 includes a main body 51 and an arm 52. The take-out mechanism 5 takes out the slide door 73 held by the holding jig 63 that has been transported to the take-out position P4 by the transport mechanism 6. Move to 53 and place. Here, as shown in the figure, the placement position P1, the posture change position P2, the assembly position P3, and the take-out position P4 are defined such that the distances between adjacent positions are the same.

  As shown in FIG. 2, the transport mechanism 6 includes a turntable 61 and a drive motor 62 disposed at a lower portion of the central portion of the turntable 61. The turntable 61 is formed in a disc shape as a whole, and is rotated, for example, counterclockwise (counterclockwise) by the drive motor 62. Further, the rotation axis of the turntable 61 is arranged at the center of a virtual circle connecting the placement position P1, the posture change position P2, the assembly position P3, and the take-out position P4. Further, four holding jigs 63, 63... For holding the spring member 91 are attached to the turntable 61. In this case, each holding jig 63, 63,... Has a tip portion (more precisely, a position of a concave portion 63a described later) at the placement position P1, the posture change position P2, the assembly position P3, and the removal position P4. It is attached at equal intervals to match.

  The holding jig 63 corresponds to a holding portion in the present invention, and includes a metal base portion 64 and metal blocks 65 to 67 as shown in FIG. The base portion 64 is formed in a rectangular plate shape as a whole in plan view. As shown in the figure, the block 65 is formed in a U-shape in plan view as a whole, and is bolted to the base portion 64. Further, as shown in FIG. 5, a step portion 65 a is formed on one of the side surfaces in the longitudinal direction of the block 65 (inside the U shape). As shown in FIG. 4, the block 66 is formed in a rectangular shape in plan view as a whole, and is bolted to the base portion 64 so as to be slightly separated from the block 65. In this case, when the blocks 65 and 66 are bolted slightly apart from each other, a concave portion 63a into which the spring member 91 can be inserted is formed by the side surfaces of both the blocks 65 and 66. The block 67 corresponds to a positioning member in the present invention. As shown in the figure, the block 67 is formed in a rectangular shape in plan view as a whole, and has a V-shaped cut in the central portion on one of the side surfaces in the longitudinal direction. A notch 67a is formed. As will be described later, the notch 67a has a function (positioning function) for determining the position of the distal end portion 91d (arm portion 91b) of the spring member 91 when the posture of the spring member 91 inserted into the recess 63a is changed. is doing. In this case, in the holding jig 63, as shown in FIG. 7, the spring member 91 is pushed down by the contact plate 32 of the posture changing mechanism 3 so that the tip 91 e is brought into contact with the side surface 65 b of the block 65. At this time, the dimensions of the blocks 65 and 67, the depth of the notches 67a, and the like are defined so that the arm portion 91b is inclined at about 60 degrees (assembled posture in the present invention).

  The control unit 7 controls each operation of the placement mechanism 2, the posture change mechanism 3, the assembly mechanism 4, the take-out mechanism 5, and the transport mechanism 6.

  Next, the overall operation of the manufacturing apparatus 101 will be described with reference to the drawings, focusing on the operation of the assembly apparatus 1.

  In this manufacturing apparatus 101, an assembling apparatus (not shown) assembles the brake release plate 77 on the bottom of the tape reel 74 after assembling the tape reel 74 to the lower case 72 b of the cartridge case 71. Next, the assembling apparatus assembles the lock member 76 on the brake release plate 77 and further assembles the brake spring 75 thereon. Next, the transport device 102 transports the lower case 72b assembled with each component to the assembly work position where the slide door 73 is assembled.

  On the other hand, in the assembling apparatus 1, the control unit 7 controls the drive motor 62 of the transport mechanism 6 so that the recesses 63 a, 63 a... Of the holding jigs 63, 63. The turntable 61 is rotated so as to be positioned at the position P2, the assembly position P3, and the take-out position P4. Next, the control unit 7 outputs a control signal for placing (inserting) the spring member 91 on the holding jig 63 to the placement mechanism 2. In response to this, the main body 21 of the mounting mechanism 2 supplies the spring member 91 supplied from the parts feeder (not shown) to the holding unit 22 and transported by the transport track 23 to the mounting position P1 on the transport mechanism 6. After being moved, it is placed (inserted) in the recess 63 a of the holding jig 63. At this time, the spring member 91 is held by the recess 63a of the holding jig 63 so that the posture of the spring member 91 can be changed. Subsequently, the control unit 7 controls the drive motor 62 of the transport mechanism 6 to rotate the turntable 61 90 degrees counterclockwise. Accordingly, the holding jig 63 holding the spring member 91 is conveyed to the posture change position P2, and the holding jig 63 located at the take-out position P4 is conveyed to the placement position P1. Thereafter, the mounting mechanism 2 mounts the spring member 91 in the recess 63a of the holding jig 63 every time the holding jig 63 is transported to the mounting position P1.

  Next, the control unit 7 outputs a control signal for changing the posture of the spring member 91 to the posture changing mechanism 3. Accordingly, as shown in FIG. 6, the main body 31 of the posture changing mechanism 3 touches the contact plate 32 on the upper side of the spring member 91 held by the holding jig 63 and conveyed to the posture changing position P2. Press down to a predetermined position while touching. At this time, the spring member 91 has a distal end portion 91d (arm portion 91b) in a direction perpendicular to the plane including the two coil portions 91a by the notch 67a (the front side direction and the back direction in the drawing). While being positioned, it is moved obliquely downward (in the direction of the arrow shown in the figure). Subsequently, as shown in FIG. 7, the main body 31 has the tip 91 e in contact with the side surface 65 b of the block 65, and one of the coil portions 91 a (the right side in FIG. The contact plate 32 is pushed down until it comes into contact. In this case, the posture of the spring member 91 is changed (corrected) to an assembly posture in which the arm portion 91b is inclined at approximately 60 degrees in a state where the distal end portion 91e is in contact with the side surface 65b of the block 65. Subsequently, the control unit 7 controls the drive motor 62 of the transport mechanism 6 to rotate the turntable 61 90 degrees counterclockwise. Thus, the holding jig 63 holding the spring member 91 whose posture has been changed is conveyed to the assembly position P3, and the holding jig 63 holding the other spring member 91 is transferred to the posture changing position P2. Thereafter, the posture changing mechanism 3 changes the posture of the spring member 91 each time the holding jig 63 holding the spring member 91 is conveyed to the posture changing position P2.

  Subsequently, the control unit 7 outputs a control signal for assembling the slide door 73 by connecting the spring member 91 and the door member 81 to the assembly mechanism 4. In response to this, the main body 41 of the assembly mechanism 4 holds the door member 81 supplied from a parts feeder (not shown) to the holding unit 42 and conveyed by the conveyance track 43. Next, the main body 41 moves the holding unit 42 downward after moving the holding unit 42 above the assembly position P3 on the transport mechanism 6. At this time, the distal end portion 91 d of the spring member 91 is inserted into the insertion hole 84 of the spring mounting portion 83 in the door member 81. In this case, since the arm portion 91b of the spring member 91 is inclined at about 60 degrees and the inner surface 85b forming the insertion hole 84 is inclined at about 60 degrees, the door member 81 is pushed downward (the holding portion 42). The tip 91d of the spring member 91 is inserted into the insertion hole 84 simply by moving the head downward. Next, as shown in FIG. 8, the main body portion 41 moves the holding portion 42 downward to a position where the distal end portion 91 d comes into contact with the wall portion 83 a of the door member 81. At this time, at least one of the distal end portion 91d and the convex portion 88 (see FIG. 12) is elastically deformed, so that the convex portion 88 enters the inner peripheral side of the distal end portion 91d folded back into a P-shape and the distal end portion. 91d and the convex part 88 engage. Thereby, the connection between the spring member 91 and the door member 81 is completed, and the slide door 73 is assembled. Subsequently, the control unit 7 controls the drive motor 62 of the transport mechanism 6 to rotate the turntable 61 90 degrees counterclockwise. As a result, the assembled slide door 73 is conveyed to the take-out position P4 while being held by the holding jig 63, and the other holding jig 63 holding the other spring member 91 whose posture has been changed is provided. It is conveyed to the assembly position P3. Thereafter, the assembly mechanism 4 repeatedly assembles the slide door 73 every time the holding jig 63 holding the spring member 91 is conveyed to the assembly position P3.

  Next, the control unit 7 outputs a control signal for taking out the assembled slide door 73 to the take-out mechanism 5. Accordingly, the main body 51 of the take-out mechanism 5 rotates the arm 52 counterclockwise to take out the slide door 73 conveyed to the take-out position P4 from the holding jig 63, and then moves the arm 52 to the right. The slide door 73 is placed on the belt conveyor 53 by rotating around. Next, the control unit 7 controls the drive motor 62 of the transport mechanism 6 to rotate the turntable 61 90 degrees counterclockwise. As a result, the holding jig 63 from which the slide door 73 has been taken out is transported to the placement position P1, and another holding jig 63 that holds the other slide door 73 is transported to the take-out position P4. Thereafter, the take-out mechanism 5 takes out the slide door 73 each time the holding jig 63 holding the slide door 73 is conveyed to the take-out position P4.

  On the other hand, the belt conveyor 53 conveys the slide door 73 to an assembly work position where the slide door 73 is assembled to the lower case 72b. Further, at the assembly work position, an assembly device (not shown) assembles the slide door 73 to the lower case 72b in which the components are assembled and conveyed by the conveyance device 102. Next, the transport device 102 transports the lower case 72b, to which the slide door 73 is assembled, to a work position where the next process is executed.

  As described above, according to the assembling apparatus 1, the holding jig 63 that holds the spring member 91 in a state where the distal end portion 91 d faces upward and the posture thereof can be changed, and the distal end portion 91 d of the spring member 91 are contacted. The posture changing mechanism 3 for changing the posture of the spring member 91 to the assembly posture by pushing down the contact plate 32 while abutting it, and the door member 81 downward while inserting the distal end portion 91d of the spring member 91 changed in posture into the insertion hole 84. By providing the assembly mechanism 4 that moves and assembles the slide door 73, the posture of the spring member 91 can be changed to the assembly posture in a short time just by pushing down the contact plate 32. Moreover, the spring member 91 and the door member 81 can be connected in a short time only by moving the door member 81 downward. Therefore, since the slide door 73 can be assembled in a short time, the efficiency of the assembly work can be sufficiently improved.

  Further, since the concave portion 63a is formed in the holding jig 63, the spring member 91 can be reliably held. In addition, since the holding jig 63 is configured by including the block 67 in which the notch 67a is formed, the tip 91d of the spring member 91 is accurately positioned when the assembly posture is changed while the configuration is simple. can do.

  Furthermore, by providing the placement mechanism 2 and the take-out mechanism 5, the placement of the spring member 91 on the holding jig 63 and the removal of the assembled slide door 73 from the holding jig 63 are automatically executed. Therefore, the assembly efficiency of the slide door 73 can be further improved.

  In addition, the mounting position P1, the posture change position P2, the assembly position P3, and the take-out position P4 are defined separately from each other, and the conveyance mechanism 6 that conveys the holding jig 63 to each of the positions P1 to P4 is provided. Since the holding jig 63 can be transported to each of the positions P1 to P4 by one transport mechanism 6, the transport mechanism 6 can be compared with a configuration in which the transport mechanism 6 is individually provided at each of the positions P1 to P4. As a result of being able to reduce the number, the assembling apparatus 1 can be simply configured accordingly.

  In addition, this invention is not limited to said structure. For example, although the transport mechanism 6 including the turntable 61 has been described above, the transport mechanism in the present invention is not limited to this. For example, the positions P1 to P4 are linearly defined, and the holding jig 63 is straight. By adopting a conveyor-type transport mechanism that transports automatically, the spring member 91 and the slide door 73 can be transported to the positions P1 to P4. Moreover, although the assembly apparatus 1 including the placement mechanism 2 and the take-out mechanism 5 has been described above, the placement mechanism 2 and the take-out mechanism 5 are not necessarily required, and the spring member 91 is placed on the holding jig 63. Further, the slide door 73 may be manually removed from the holding jig 63. Furthermore, although the assembly apparatus 1 that executes the placement of the spring member 91, the posture change of the spring member 91, the assembly of the slide door 73, and the removal of the slide door 73 at different positions has been described above, these are all performed at the same position. A configuration can also be adopted.
