Description of the Related Art There is a device configured to store an article and to hermetically pack the article by accommodating a cover tape.

In the conventional packing tape body, the cover tape is adhered to the carrier tape by adhesion by thermocompression bonding.

[0004]

The packing tape body containing the articles is generally wound in a reel shape for easy storage and transportation. When unpacking, the packing tape body is used. While unrolling the body from the reel, the cover tape is forcibly peeled off the thermocompression bonding portion from the carrier tape in one direction.

At this time, in order for the cover tape to be smoothly peeled from the carrier tape, the peel strength between the cover tape and the carrier tape needs to be maintained at a predetermined value. However, it is difficult to control the thermocompression bonding conditions for maintaining the peel strength at a predetermined value, and complicated work is required to manage the thermocompression bonding conditions. Further, the peeled cover tape may be damaged or the cover tape or the carrier tape may have an adhered mark, so that the cover tape and the carrier tape cannot be reused. Therefore, conventionally, the cover tape and carrier tape after peeling are cut by a shredder or the like and discarded.

It is an object of the present invention to provide a reusable packing tape body which is easy to pack and unpack.

The above and other objects and novel features of the present invention will be apparent from the description of this specification and the accompanying drawings.

The outline of a typical invention among the inventions disclosed in the present application is as follows.

That is, in the packing tape body, a lid for closing the opening of the cavity is rotatably supported at one end by a carrier tape in which a plurality of cavities for accommodating objects to be packed are arranged in the longitudinal direction. It is characterized in that it is openably and closably attached to the opening of the cavity, and that the lid is provided with a stopper for preventing the opening of the lid when the cavity is closed.

[0010]

In the above-mentioned means, the article is accommodated in the cavity of the carrier tape with the lid opened. Subsequently, when the lid is closed, the stopper of the lid prevents the lid from being opened naturally. In this state, the packing tape body is wound around a reel and stored or transported.
After that, when the packing tape body is unpacked, when the lid is forcibly opened in the state where the packing tape body is unreeled in sequence from the reel, the stopper is released and the cavity is opened. The article to be packed can be removed from the cavity. In this way, according to the above-mentioned means, the lid is integrally assembled to the carrier tape, so that the packing work and the unpacking work are easy. Moreover, since the carrier tape and the lid after unpacking are not damaged, the packing tape body can be reused.

The relationship between the male hinge 23 and the female hinge 19 is set so as to be released. That is, the lid-side stopper 25 that is engageable with the carrier tape-side stopper 26 that is formed by the outer opening edge portion of the long hole 20 is formed by the outer edge portion of the male hinge 23.

Next, a method of packing the QFP / IC with the packing tape body having the above structure will be described. The lid opening / closing device shown in FIG. 3 is used for this packaging method. The lid opening / closing device 30 includes a packing tape body feeding device, and although not shown in the drawings, this feeding device extends the reel reel, the take-up reel, and the packaging tape body 10 between both reels. And a feed sprocket for engaging the small holes 13 formed in the carrier tape 11 to intermittently feed the packaging tape body 10 in one direction.

Packing tape body 10 stretched between both reels
A lid opening stage 31 is set at an appropriate position in the middle part of the QFP IC1.
A collet 32 for vacuum-holding and holding is provided so as to reciprocate between a loading stage (not shown) for dispensing the QFP / IC1.

On the upstream side of the lid opening stage 31, a wedge-shaped opening tool 34 is supported by a stand 33 and is arranged close to the upper position of the packing tape body 10. Opener 34
Is equipped with a pair of right and left push-up slopes 35, 35,
Both slopes 35 and 35 are symmetrically butted so as to form one edge of a triangular pyramid. The opener 34 has both push-up slopes 35, 35 with the apex side of one edge of the triangular pyramid facing the upstream side, and the apex is the packaging tape body 10.
The left and right lids 12 are arranged symmetrically so as to match the boundary line between the lids 12. That is, the left and right push-up slopes 35, 35 of the opening tool 34 form an isosceles triangle in the cross section orthogonal to the boundary line between the left and right lids 12, and the cross-sectional area gradually increases toward the downstream side. It is supposed to expand.

On the downstream side of the lid opening stage 31, the closing tool 3 is provided.
6 is arranged close to the upper position of the packing tape body 10. The closing tool 36 includes a pair of left and right push-down plates 37, 37. The upstream end portions of the push-down plates 37, 37 are provided outside the left and right lids 12, 12 in a state of being erected at the end of the lid opening stage 31. It is arranged so as to press from each. Further, the two push-down plates 37, 37 are inclined such that the inner end sides 38, 38 thereof gradually become lower as they go downstream, and the left and right lids 12, 12 which are erected with the movement of the packing tape body 10. Each is designed to urge the force to push it inward.

When the lid opening / closing device 30 having the above-described structure is used to pack the QFP / IC 1 in the packing tape body 10, the empty packing tape body 10 is stretched between both reels. When the stretched packing tape body 10 is sequentially fed in one direction by the feeding device, the packing tape body 10 is laid down on the upper surface of the carrier tape 11 to close the cavity 14 to the boundary line between the pair of left and right lids 12, 12. The tip of the opening tool 34 gradually enters. With the entry of the tip of the opening tool 34, the left and right push-up slopes 35, 35 are brought into sliding contact with the lower surfaces of the left and right lids 12, 12.
12 is gradually raised. That is, as the lids 12 are pushed up and the free ends thereof are pushed up by the inclined surfaces 35, the shaft portions 24, 24 of the male hinge 23 rotate in the brackets 21, 21 of the female hinge 19, It stands up with respect to the carrier tape 11 centering on the hinge side end.

Before the lid 12 is urged by the opening tool 34 to generate rotational force, the lid-side stopper 25 is engaged with the carrier tape-side stopper 26 from the upper surface side of the carrier tape 11. The state of lying on the upper surface of the tape 11 is maintained. That is, the lid 12 keeps the cavity 14 closed. In this state,
When the lid 12 is urged by the pushing force in the direction in which it is erected by the opening tool 34, the male hinge 23 bends upward due to its own elastic force, and thus the lid-side stopper 25.
Goes through the carrier tape side stopper 26 from the upper side to the lower side, so that the engagement between the lid side stopper 25 and the carrier tape side stopper 26 is automatically released. As a result, the lid 12 can be rotated around the hinge-side end portion, so that the lid 12 stands up against the carrier tape 11 and the cavity 14 can be opened.

When the lid 12 is upright,
Since the flat surfaces located above and below the shaft portion 24 of the male hinge 23 are in close contact with the inner surface of the bracket 21 and the upper surface of the carrier tape 11 at the opening edge portion of the elongated hole 20, respectively, the lid 12 is placed in its upright state. Will be maintained. The cavity 12 passes through the lid opening stage 31 while the lid 12 is in the open state in which the lid 12 is kept upright. While the cavity 14 whose lid is opened passes through the lid opening stage 31, the collet 32 inserts the QFP / IC1 picked up from the loading stage into the cavity 14 and puts it down.

In the lid opening stage 31, the QFP / IC
When the cavity 14 accommodating 1 advances to the closing tool 36, the upper ends of the left and right push-down plates 37, 37 stand upright in the cavity 14 on the left and right lids 12, 12.
From the outside respectively. After this, packing tape body 1
When the lid 12 moves further downstream with the feeding of 0,
Since the pushing-down plate 37 slidingly contacting the lid 12 is gradually lowered, the lid 12 is pushed down and the cavity 14 is closed.

When the lid 12 is pushed down, the lid side stopper 2
5 is brought into contact with the cavity side stopper 26 from the lower side first. In this state, when the lid 12 is further urged downward by the push-down plate 37, the male hinge 23 is bent downward by its own elastic force, so that the lid side stopper 25 causes the carrier tape side stopper 26. Since it goes through from the lower side to the upper side, the lid side stopper 25 is in a state of being engaged with the carrier tape side stopper 26 from the upper side.
As a result, the lid 12 is prevented from rotating around the hinge-side end portion, falls over the carrier tape 11, and can maintain the closed state of the cavity 14.

By repeating the opening / closing operation of the lid 12 as described above, the cavity 14 of the carrier tape 11 is filled with Q.
FP / IC1 is housed, and the housed QFP / IC
1 is covered with a lid 12 and sequentially packed. Further, the packing tape body 10 in which the QFP / IC1 group is packed is wound on the take-up reel.

QFP / IC packed as described above
The lid opening / closing device 30 shown in FIG. 3 is also used in the unpacking method for taking out 1 from the packing tape body 10.
That is, the difference between the unpacking method and the packing method is that the QF
The actual packing tape body 10 in which the P / IC1 group is packed is set in the lid opening / closing device 30, and the collet 32 is the QF.
This is the point where the PIC1 is picked up from the cavity 14 and put down on the unloading stage.
Therefore, the description of the unpacking method is omitted because it follows the packing method.
