Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tape-shaped material such as a carrier tape or a cover tape used for a tape-shaped package which is useful for accommodating and transporting and storing a large number of various electronic parts and precision instrument parts.

[0002]

[Prior art]

 Conventionally, in the packaging of the above-mentioned parts, a concave container for individually storing the parts, which is formed by press molding, vacuum forming, etc. from one flat thermoplastic resin sheet, is arranged in the flow direction via the flange part. Prepare a large number of carrier tapes in a row, store the parts in each concave container, and then cover the opening of each concave container with a flexible cover tape that has an adhesive layer and seal with the flange surface. However, a method was adopted in which the taping work of winding and the storage of parts and the assembly of a tape-shaped package were performed at the same time. This carrier tape was delivered to parts makers by winding it in a single row on reels of φ178 or φ330 in a length of 12 to 40 m and delivered to parts makers. In order to increase the winding speed, the winding amount per reel has been lengthened by winding with a large diameter or traverse winding. In addition, cover tapes have been lengthened from a length of about 200 m to a length of about 700 to 1,000 m in a single line on the core and are now being delivered to parts manufacturers.

[Problems to be solved by the device]

 However, if the machine stops many times during the taping work due to an obstacle and the tape material is lost each time, it is possible to judge whether the length of one reel in the shipping form remains at the end of the winding. There were times when it didn't work. After starting the taping work, when it is near the end and it is found that the tape material is shorter than the specified length in the shipping form, it is necessary to remove the cover tape and take out the parts from the concave container. In many cases, even if there might be one reel length left, I was throwing it away without fully checking it. Therefore, it is an object of the present invention to easily determine whether or not one reel length in the shipping form is left near the end of winding of the tape material during the taping operation. It provides body material.

[0004]

[Means for Solving the Problems]

 The tape-shaped package material according to the present invention comprises a carrier tape having a shape in which a large number of concave containers for accommodating individual parts are continuously provided in the flow direction via flanges, and the upper surface of the concave container is covered and a flange portion is formed. It is characterized in that at least one of the cover tapes to be combined with the above is provided with a mark indicating the remaining amount at a position of one reel from the end.

Hereinafter, the embodiments of the present invention will be described in more detail with reference to FIGS. 1 to 3. FIG. 1 is a perspective view showing a state in which a tape-shaped package obtained by the present invention is wound into a roll. A carrier tape 1 is provided with a concave container 3 in which parts 2 are individually housed. It has a shape in which a large number are continuously provided in the flow direction through the formed flange portions 6. Reference numeral 4 is a small hole for guiding, which is formed in one row on one side of the flange portion 6. Reference numeral 5 is a cover tape which covers the opening of each concave container 3 after the components 2 are individually stored, and is firmly sealed to the carrier tape 1 at the flange 6 to form a tape-shaped package. ing. FIGS. 2 (a) and 2 (b) are plan views showing the carrier tape 1 and the cover tape 5 in a further enlarged manner. One side of each tape is, for example, the user's shipping form from the end of each tape. Marks 7 indicating the respective remaining amounts are provided at the length of one reel. The mark may be of any shape or color, preferably one detected by an optical detector. In the carrier tape 1 after molding, the length of one reel is wound around the reel, the mark 7 is provided by means of printing or the like, and then the specified length of the delivery form to the user is wound. After the cover tape 5 is slit to the standard width, when the length of one reel in the shipping form of the user is wound in the winding process on the core, the mark 7 is provided by means of printing or the like, and then the user The specified length of the delivery form is rolled up.

FIG. 3 is an explanatory view showing a process in which the component 2 is housed in the carrier tape 1 to form a tape-shaped package and wound up on a reel. The carrier tape 1 sent from the reel 11 can detect the mark 7 indicating the remaining amount in the optical detector 12, and the component 2 is supplied from the component inserter 13 to each concave container 3 thereof. Next, the cover tape 5 fed from the take-up reel 14 covers the upper surface of each concave container 3 and is firmly bonded to the carrier tape 1 at the flange portion 6 by the heat sealer 15 to form the tape-shaped package 16. Then, it is wound up on reel 17.

Examples of the tape-shaped packaging material of the present invention include those made of conventionally known thermoplastic resins such as polyester, polystyrene, polypropylene, polycarbonate, and polyvinyl chloride. In the case of materials that are easily destroyed by static electricity, those materials in which a conductivity-imparting agent such as carbon black is kneaded or applied are used.

[0008]

[Action]

 Since the tape-shaped packaging material of the present invention is provided with a mark indicating the remaining amount at the length of one reel in the shipping form of the user, the operator can easily detect the remaining amount of the tape material by the detection signal. You can know the quantity.

[0009]

【Example】

 The carrier tape with a width of 12 mm is delivered to the parts manufacturer by traverse winding 46,500 pockets (372 m), and the shipping form from the parts manufacturer to the set manufacturer is 2,100 pockets (16.8 m) per reel. Ships in line. Therefore, in the process of forming the carrier tape and then winding it up on the reel, use an ink jet printer at a position approximately 1.2 mm inside from the end of the tape between the feed holes of the 2,100th pocket. A black circle with a diameter of 1 mm was printed with a dry solvent-based ink, dried for about 2 seconds, and then the specified number of pockets was wound on a reel. In addition, the cover tape corresponding to the above carrier tape has a width of 9.5 mm and is delivered to component makers by winding it around a core for 750 m. In the process of slitting the original film to the specified width and winding it around the core, At 16.8 m from the beginning, a black circle with a diameter of 1 mm was printed at a position approximately 1.2 mm inside from the end of the tape in the same manner as the carrier tape, and the tape was wound for a specified length. On the black carrier tape in which the conductivity-imparting agent was kneaded, white circles with a diameter of 1 mm were printed by the same method as described above.

[0010]

[Effect of device]

 With the tape material for the tape-shaped package of the present invention, even if the tape material is lost due to a machine failure during taping work, the operator can leave one reel length in the shipping form. Since it is easy to determine whether or not the tape material is insufficient during taping work, there is no need to remove the cover tape to take out the parts and redo the taping work. However, it was not possible to discard it due to inaccurate judgment, and the efficiency of taping work was improved and the cost was reduced.
