  The feeder 2 has another set of the transport mechanism 30 and the peeling mechanism unit 40 shown in FIG. 4 on the back side of the paper surface of FIG. 4, and can supply the electronic component 4 from the two supply tapes 60.

  The transport mechanism 30 drives the sprocket 31 via a sprocket 31 having a steep gear that drives a sprocket hole 64 provided in the supply tape 60, a worm wheel 32 provided on the concentric shaft thereof, and a worm gear 33. A sprocket drive motor 34 that presses, and a pressing plate 36 that presses the supply tape 60 against a tape chute (moving path on which the supply tape 60 moves while sliding) 2s by a spring 35 so that the sprocket can reliably deliver the supply tape 60. , And other support members.

  On the other hand, the peeling mechanism unit 40 is opposed to the driven sprocket 41 driven by the movement of the sprocket hole 64, the peeling gear (peeling rotating body) 42 provided on the concentric shaft of the sprocket 41, and the peeling gear. An opposing peeling gear (opposed peeling rotor) 43 provided, a peeling pressing portion 44 for pressing the opposing peeling gear against the peeling gear, a peeling portion 45 having a gentle curve provided on the tip side of the peeling mechanism portion, It has a guide roller 46 for guiding the peeled cover tape 61b, and a cover tape housing portion 70 for housing the peeled cover tape 61b. In the present embodiment, the coupling portion between the peeling gear 42 and the counter peeling gear 43 is referred to as a peeling coupling portion 48. The peeling pressing part 44 presses the opposing peeling gear 43 against the peeling gear 42 with a constant pressing force by a spring 44b with 44a as a pressing fulcrum.

  FIG. 5 is a view showing a first embodiment of the peeling mechanism 40 of the feeder according to the embodiment. FIG. 5A is a view of the vicinity of the peel coupling portion 48 in FIG. FIG.5 (b) is the figure seen from the direction of arrow A in Fig.5 (a).

  First, operation | movement of the peeling mechanism part 40 is demonstrated using FIG. 4, FIG. 5 (a). Before the feeder 2 is fixed to the feeder cart 50, the supply tape 60 is manually set in the feeder 2. That is, the supply tape 60 is separated into the carrier tape 62 and the cover tape 61 at the peeling portion 45. The carrier tape 62 is brought into a state where the sprocket hole 64 is engaged with the sprocket 31 so that the supply tape can be driven. On the other hand, the peeled cover tape 61 b is reversed by the peeling portion 45, passes through the guide roller 46 and the peeling coupling portion 48, and is set in a state where the tip is housed in the cover tape housing portion 70.

Thereafter, when the mounting operation is started, the supply tape 60 moves on the tape chute 2s by the drive sprocket 31. Along with this movement, the driven sprocket 41 is rotated by the sprocket hole 64 of the carrier tape 62. By the rotation of the driven sprocket 41, the separation gear 42 fixed to the driven sprocket 41 on the concentric shaft also rotates, and the opposing separation gear 43 that is gear-coupled by the separation gear and the separation coupling portion 48 also rotates.
At this time, the cover tape 61 b moves while being pressed against the peeling gear by the peeling pressing portion 44 at the peeling coupling portion 48. Therefore, after the supply tape 60 is manually set once, the cover tape 61a is separated by the separating portion 45, turned upside down and moved toward the peeling gear 42, and after passing through the peeling gear, the cover tape accommodating portion 70 is passed. It is stored in.

  FIG. 6 is a view showing a portion surrounded by an ellipse in FIG. 4 in the first example of the cover tape housing portion 70 in the present embodiment. FIG. 7 is a view showing a portion corresponding to the portion surrounded by the ellipse of the cover tape housing portion 70 ′ in the prior art. 6 (a) and 7 (a) are diagrams showing a view from the top of the page of FIG. FIGS. 6B and 7B are views as seen from the insertion side of the supply tape 60 of the feeder 2. FIG. 6C is a view showing a state in which the opening / closing lid of the cover tape housing portion 70 is opened. 6 and 7, parts having the same configuration are denoted by the same reference numerals.

  The cover tape accommodating portion 70 takes out the respective storage chambers 77 for accommodating the cover tapes 61b peeled off by the two peeling mechanism portions 40, the covers 72 provided on both sides of the cover tape accommodating portion 70, and the cover tape 61b. And an open / close lid 71. The storage chamber 77 has a partition wall 73 at a position corresponding to the width of the supply tape 60 on the opposite side of the cover 72. The dividing wall 73 may be configured in a box shape having a cavity, or may be configured by two thin plates. Accordingly, each peeled cover tape 61 b is stored in the corresponding storage portion 77. The cover 72 is fixed to the feeder body with screws 72b provided on the top and bottom.

  The open / close lid 71 is composed of a single plate having an inverted concave shape so that the two storage portions 77 can be opened and closed at a time, and operates the convex portion 71t provided at the upper portion to rotate the lower portion. The storage portion 77 is opened and closed so as to be rotatable about the shaft 74. Further, the open / close lid 71 can be kept closed by a magnet 75 provided in the feeder body. Furthermore, a protrusion 73t from which a part of the dividing wall 73 protrudes is provided in the recess of the opening / closing lid 71, and the lower portion of the front surface of the opening / closing lid 71 is an end portion 76 of the storage portion 77 located on the left and right of the protrusion 73t. The upper surface of the lower end of the storage portion 77 is restricted so as not to rotate more than 90 degrees. As a result, the opening / closing lid 71 is not rotated 90 degrees or more so that the movement of the supply tape 60 to the insertion port of the feeder 2 is not disturbed. By making the end portion 76 of the storage portion 77 to be regulated longer outward, it is possible to more reliably serve as a stopper. From the viewpoint of the role of the stopper, the protruding portion 73t is not necessarily provided, and the end portion 76 of the accommodating portion 77 to be regulated may be lengthened by providing the rotating shaft 74 on the depth side from the insertion port.

  Further, the protruding portion 73t can serve to prevent the opening / closing lid 71 from coming off during the maintenance. If the cover 72 on the side surface of the feeder 2 is removed for maintenance, the open / close lid is removed together with the rotary shaft 74 in the prior art. On the other hand, in the first embodiment, the rotary shaft 74 is rotatably supported by the protrusion 73t. Since the protrusion 73t is engaged with the concave portion of the opening / closing lid 71, the opening / closing lid 71 is prevented from moving left and right and does not come off.

  On the other hand, the conventional cover tape accommodating portion 70 ′ shown in FIG. 7 has open / close lids 71 A and 71 B that can be opened and closed independently with respect to the two accommodating portions 77. Further, as described above, the cover tape housing portion 70 ′ does not have the protruding portion 73 t on the dividing wall 73. Other points are the same as those in the first embodiment.

  According to the first embodiment described above, a common opening / closing lid is provided for the two storage units, and the opening / closing operation of the opening / closing lid 71 can be performed at a time, and the cover tape after the two supply tapes 60 are peeled off. An operator at the time of processing 61b can reduce troublesomeness and can provide a feeder that can reduce processing time.

  Further, according to the first embodiment described above, it is possible to prevent the opening / closing lid 71 from being removed by providing the protruding portion 73t on the dividing wall 73 and rotatably supporting the rotating shaft 74 on the protruding portion 73t.

FIG. 8 is a view showing a second example of the cover tape accommodating portion 70 in the present embodiment, and corresponds to FIG. 6B.
A difference of the second embodiment from the first embodiment is that the partition wall 73 is not provided, and the storage portion 77 is configured by one room. Other points are the same as those in the first embodiment.

  According to the second embodiment, the volume of the storage portion can be increased, and the processing frequency of the cover tape 61b after peeling can be reduced.

  Also in the second embodiment, since the cover tape 61b after the two supply tapes 60 are peeled off can be extracted at the same time, a feeder that can easily process the cover tape 61b after the peeling can be provided.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various embodiments described above without departing from the spirit of the present invention. It encompasses alternatives, modifications or variations.
