Is forcibly discharged from the exit end of the guideway C.

In FIGS. 1, 2, 4, 7 and 8, the symbol E
Is disposed on the discharge side of the cover tape 4B of the transport mechanism D and accommodates the cover tape 4B transported by the transport mechanism, and is formed of a transparent synthetic resin such as an acrylic resin and is freely openable and closable. Openable lid 28 and case body 2
9 is a relatively small storage case having a substantially cassette tape case shape. As can be seen from FIGS. 1 and 2, the case main body 29 of the storage case E is fixed to the vertical mounting plate portion 2B via a screw 30, and a cutout opening 31 is provided in a bottom wall 29A. In addition, the rope pulley 10 as a driven pulley is disposed inside the notch opening 31 so as to face the pulley 1.
With the rotation of 0 in the clockwise direction, the downward going portion 9A of the endless rubber rope 9 enters the storage case A from below the pulley 10 and moves to the upward going portion 9B.
Accordingly, when the front end of the cover tape 4B conveyed rearward along the guide path C by the transfer mechanism D reaches the exit end of the guide path, the cover tape 4B moves between the rope pulley 10 and the pinch roller 26 that rotate in opposite directions. The storage case E is sandwiched between
And will be automatically stored.

In the illustrated example, the driven pulley 10 has a support shaft 10A penetrating through the rear wall 29B and the vertical mounting plate portion 2B of the case body 29 of the storage case E and protruding to the rear side thereof. As shown in FIGS. 4 and 7, a first pulley 32 is coaxially fixed to the driven pulley 10 on the protruding shaft portion 10A '. On the other hand, above the first pulley 32, a second pulley 33 is pivotally supported by the rear wall 29B of the case main body, and its support shaft 33A penetrates the rear wall and projects to the front side thereof. A small take-up spool F for taking up the cover tape 4B can be detachably fitted to the protruding shaft portion 33A '. This take-up spool F It is good to form with a cheap material, such as a synthetic resin and a paperboard, so that it can be disposable. And
An endless transmission rope 34 similar to the rubber rope 9 is wound around the first and second pulleys 32, 33. When the driven pulley 10 is rotated, the transmission pulley 34 The second pulley 33, and thus also the take-up spool F, is adapted to be driven to rotate clockwise in FIGS. An adhesive is thinly applied to the outer peripheral surface FA 'of the boss portion FA of the take-up spool F fitted to the projecting shaft portion 3A' of the second pulley 33, and the cover tape 4B which enters the storage case E is provided.
Can be easily wound around the outer peripheral surface FA '. A double-sided adhesive tape may be used instead of the adhesive on the outer peripheral surface FA 'of the boss.

In FIGS. 1 and 2, reference numeral 35 denotes an elastic band-shaped guide plate for guiding the leading end of the cover tape 4B introduced into the storage case E to the outer peripheral surface FA 'of the boss of the take-up spool. As shown in FIGS. 1 and 2, the guide plate 35 has an arch-like curved shape, and its base end is brought close to the downstream end of the endless rubber rope 9 as a conveyor rope. It is fixed to the case body 29 of the storage case E in a state where its tip is located near the boss outer peripheral surface FA 'of the take-up spool F. Accordingly, when the tip of the cover tape 4B is moved and displaced by being guided by the guide plate 35, the tip of the tape is moved to the outer circumferential surface F of the winding spool boss FA.
When the take-up spool F is rotated clockwise because it is guided by A 'and automatically adheres to the adhesive surface, the cover tape 4B is automatically taken up by the take-up spool F accordingly. Will be done. In this case, since the take-up spool is small, unlike the conventional mechanism using a large take-up reel, the tension applied to the cover tape due to an increase in the take-up amount or take-up radius of the cover tape is increased. Since the fluctuation is extremely small, the winding can be performed extremely smoothly.

In the embodiment of the present invention described in detail with reference to the drawings, the leading end of the cover tape 4B led out through the peeling / turning portion 5 of the cover tape 4B is connected to the tape guide 5A. The pulley 8 is sandwiched between the wheel 7, which is a pair of rotating members A and B that rotate in the opposite direction and the driven pulley 8, and is wound around the pulley 8 and the driven pulley 10, and the cover tape 4 </ b> B is transported. Initial setting is performed by elastically pressing the peripheral surface of the hub 7B of the wheel 7 through the endless rubber rope 9 constituting the conveyer rope.

After the initial setting is performed as described above, when the above-described ratchet mechanism is driven to intermittently rotate the wheel 7 as one rotating member A counterclockwise in FIGS. Since the driving pulley 8 as the rotating member B is intermittently rotated clockwise in conjunction with this, the endless rubber rope 9 wound around the driving pulley 8 and the driven pulley 10 is covered with a cover tape 4B. Since the cover tape circulates clockwise while being elastically pressed against the guide surface 23 of the guide path C, the cover tape is slid along the guide path and conveyed toward the outlet end. Next, the leading end of the cover tape 4B thus conveyed to the outlet end is drawn between the driven pulley 10 and the pinch roller 26, which rotate in opposite directions, and with the intermittent rotation thereof. Is intermittently fed into the storage case E, and is automatically wound on the winding spool E as described above.

Next, when the winding amount of the cover tape 4B by the winding spool F increases and the winding radius approaches the radius of the disk-shaped flange F ″ of the winding spool, the winding amount is reduced. The increase can be easily visually recognized from the outside through the transparent opening / closing lid 28 of the storage case E. In this case, the opening / closing lid is opened, the winding spool F is removed, and the cover connected to the wound cover tape is opened. Cut off the tape part with scissors or the like and cut it off, and immediately attach another winding spool F prepared and wind the leading end of the separated cover tape around this, without interrupting the work. The tape feeder can be operated continuously, and is wound on the take-up spool F as described above, and is compacted into a spiral. The cover tape 4B can be removed from the boss portion FA of the take-up spool in the form of a spiral and discarded, and the take-up spool F is made of an inexpensive material so as to be disposable. In some cases, the cover tape can be discarded together with the take-up spool F without removing the wound cover tape, so that the cover tape can be more easily discarded.

Further, in the cover tape transport mechanism D of the present invention, the endless rubber rope 9 as a conveyor rope is connected to the driving pulley 8, the driven pulley 10, etc.
A part of the outer peripheral surface of the rope portion that has been wrapped around the groove is partially covered with the cover tape 4.
Since the tape 4B is slid and conveyed along the guide path C while being in frictional contact with the central axis of B, there is no need to worry about inducing tape clogging on the way, and the tape can be conveyed extremely smoothly. it can.

As described above, one embodiment of the present invention has been described in detail with reference to the drawings. However, the present invention is not limited to the embodiment, and various modifications may be made within the scope of the claims. Can be implemented with modifications.

Since the present invention is configured as described above, according to the present invention, the cover tape can be easily and easily removed without using a take-up reel as means for forcibly separating the cover tape from the tape body of the electronic component housing tape. In addition to being able to peel off the cover tape in a predetermined direction, the cover tape that has been peeled off can be automatically assembled into a compact form so that it can be easily disposed of. Thus, a cover tape processing apparatus capable of realizing efficient operation of the tape feeder can be obtained, and a great effect can be exhibited in combination with the above-mentioned advantages.
