Description

  The present invention relates to a cover that is peeled off from a main body of a storage tape and wound around a take-up reel in a supply operation process of a tape feeder that uses the electronic component storage tape to supply each electronic component stored in the tape. The present invention relates to a cover tape processing apparatus for processing a tape.

  While pitch feeding the electronic component storage tape wound around the supply reel, the cover tape attached to the tape main body is forcibly peeled from the tape main body, and each electronic component is moved to the pickup position of the electronic component mounting apparatus. A tape feeder that is fed and uses a take-up reel as a mechanism for peeling the cover tape from the tape body of the electronic component storage tape is known. Since it takes time and labor to remove the cover tape wound around the take-up reel, it is difficult to operate the tape feeder efficiently.

Therefore, the present applicant has previously adopted a pair of cover tape processing rollers in place of the take-up reel as means for forcibly peeling the cover tape from the tape main body of the electronic component storage tape in the tape feeder. A cover tape processing apparatus has been proposed in which the cover tape that has passed through is accommodated in the cover tape housing case as it is.

  FIGS. 8 to 13 show a suction device C ′ according to the second embodiment of the present invention. The main difference between the second embodiment and the first embodiment is that the suction device C ′ is different from the first embodiment. The specific configuration and operation are different from those of the suction device C of the first embodiment, and the other main components such as the housing and the trash container are described in the description of the first embodiment. The description is omitted to avoid duplication since it is substantially the same.

  In the second embodiment, the high-speed air flow generating means has an annular tunnel-like air passage 5 'and swirls while being swirled in the air passage by the pressure air blown tangentially into the air passage 5'. It consists of the blowing nozzle N 'provided with the turning ring 14 comprised so that a downward airflow might be generated. The blowout nozzle N ′, like the blowout nozzle N, includes a hopper-like opening 6 that penetrates up and down and communicates with the inlet 3 of the cover tape T provided on the top wall A2 of the housing A. .

  Similarly to the first embodiment, the guide cylinder for guiding the high-speed air flow generated from the blowout nozzle N ′ serving as the high-speed air flow generating means to the lower side is also composed of the cylindrical body G having a circular cross section, and the coupler 7 or the outward flange. The lower end opening 6A of the hopper-like opening 6 of the blowing nozzle N ′ and a vertical groove 14B of the swiveling ring 14 to be described later are provided so as to hang down from the lower surface side of the blowing nozzle N ′.

  A pair of linear air introduction passages 8A 'and 8B' communicating with the annular tunnel-like air passage 5 'are provided in the blowout nozzle N' so as to extend in parallel and tangential to each other. In the air introduction passages 8A ′ and 8B ′, as in the first embodiment, air supply pipes 9A ′ and 9B ′ respectively connected to an air supply pipe connected to an external pressure air source are provided with inlet joints. 10A 'and 10B' are connected to each other. The upper end surface 11 of the blowout nozzle N ′ is formed as a flat annular top surface similar to that of the first embodiment, and the inlet 3 of the top wall A2 of the housing A is connected to the hopper-like opening from below. 6 is screwed with a plurality of press screws 13 in such a manner that it is in close contact with the lower surface of the top wall A2.

  The swirling ring 14 of the blowout nozzle N ′ is a high-speed airflow generating ring as a swirling descending airflow, and a plurality of radial grooves 14A are formed on the annular upper surface side, some of which are A vertical groove 14B is provided on the inner peripheral side of the ring for jetting the pressure air vertically downward. In the illustrated example, twelve radial grooves 14A are formed in the swivel ring 14, and they are alternately arranged, that is, six grooves 14A form the longitudinal grooves 14B inside each other. I have. 15 is a small bearing ball for smoothing the swiveling motion of the swivel ring 14, and these balls 15 can roll into an annular groove 16 of an annular member provided inside the coupler 7 or the outward flange. Contained.

Next, the operation of the second embodiment of the present invention described with reference to FIGS.
In use, as in the case of the first embodiment, first, as shown in FIG. 5, the garbage container B is disposed in the housing A, and the opening / closing door 1 of the opening 2 is closed.
Subsequently, the pressure air is introduced into the annular air passage 5 ′ through the air supply pipes 9A ′ and 9B ′, the pair of linear air introduction paths 8A ′ and 8B ′, and the like.
Then, since it flows along the tangential direction from both sides into the annular air passage 5 ′ through the air introduction passages 8A ′ and 8B ′, the swiveling ring 14 is unidirectional, in the example shown in FIG. It can be swung clockwise. In this case, since the swivel ring 14 includes the plurality of radial grooves 14 and the vertical grooves 14B as described above, the swirl ring 14 can be easily rotated at high speed by receiving air pressure like a windmill rotating by wind power, and while turning. High-speed air is generated in the cylindrical body G through a plurality of vertical grooves 14B so as to generate a high-speed swirling downflow. Therefore, in this state, when the front end portion of the cover tape T wound around the take-up reel member is inserted into the insertion port 3 of the housing top wall A2, the cover tape is unwound by the high-speed swirling descending airflow and spirally formed. It is automatically taken in and stored in the garbage container B at high speed while turning.

  In the figure, A3 is a screen door-shaped exhaust window, A4 is a caster provided at each of the four corners of the bottom of the housing A, B ′ is a finger insertion port provided on the opposite side wall of the garbage container B, and B ″ is A lid 17 of the garbage container B having a through-hole 16 for passing the tape T in the center is a lid B ″ or a fixture for fixing the housing A. Although not shown in the drawing, many small exhaust holes are formed at appropriate positions on the side wall of the garbage container B.

The external dimensions of each of the above-described embodiments are as follows: the width is 250 mm, the depth is 300 mm, the height is 920 mm, and the weight is 15 kg.
The suction-corresponding widths are 8 mm, 12 mm, 16 mm, and 24 mm, and the removal speed of the cover tape varies depending on the tape material and width. For example, in the case of an 8 mm wide tape, the speed per second is about 10 m, which is extremely high. Further, since the tape to be removed is stored in the garbage container B as a tape storage container having a large volume, the tape storage amount can be greatly increased.

  Since the present invention is configured as described above and has the functions as described above, the cover tape removal and processing speed or processing speed can be remarkably increased, and the storage capacity can be greatly increased. In addition, the tape feeder can greatly contribute to the efficient operation of the tape feeder, and hence the efficiency of the surface mounting operation of the printed circuit board, and the utility value in the electronic equipment industry is great.
