Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a taping device for holding, for example, a small electronic component on an embossed tape, winding it up in a roll shape, and shipping it. 2. Description of the Related Art For the convenience of users, small electronic components such as transistors and diodes are often shipped in the form of being held on tape and wound up in a roll. As the above-mentioned tape, there is an embossed tape in which the component storage concave portions are formed in an embossed shape at equal intervals,
While the tape is intermittently fed, the electronic components are sequentially stored in the storage recesses, and the openings of the storage recesses are sealed with a series of sealing tapes so that the stored electronic components do not fall off. The embossed tape to which the article is held and to which the sealing tape is attached is wound up in a roll shape and shipped. A conventional taping device intermittently feeds a roll of an embossed tape, a roll of a sealing tape, and an embossed tape pulled out from the roll of the embossed tape, so that the electronic components are removed. After being stored, the sealing tape is stacked and transported, and the mechanism for winding the tape thus taped onto the reel is all mounted in a fixed fixed position, and therefore, there are the following problems. . [0004] Electronic components to be loaded into each accommodating recess are sequentially sent at a fixed position during the conveyance of the embossed tape. For example, when the embossed tape roll is completely consumed, or when the sealing tape is used. When the tape is consumed, the entire taping mechanism must be temporarily stopped in order to load a new embossed tape roll and a sealing tape roll, so that continuous taping is not performed, resulting in poor efficiency. Was. [0005] The above also includes the problem that the changeover for changing the production lot is troublesome.
In other words, when a certain production lot is finished in a state where the embossed tape roll has not been consumed, the embossed tape roll is replaced with a new one for taping for the next production lot, and the product tape is wound at the same time. Also, the reel must be replaced with another reel. In this case, the taping device must be stopped for a certain period of time, and there is a problem that continuity of manufacturing cannot be ensured. The present invention has been conceived in view of the above-mentioned circumstances, and is intended to continuously perform taping operation even when one embossed tape roll or one sealing tape roll is consumed. Or a new taping device configured so that taping operation can be performed continuously without the need for time such as tape setup change in response to a change in the production lot. Is the task. [0007] In order to solve the above problems, the present invention employs the following technical means. That is, the invention of the present application is to sequentially store articles in each of the article storage recesses while feeding an embossed tape having a large number of article storage recesses formed at equal intervals, and to open the opening of each of the storage recesses with a series of sealing tapes. A taping device for sealing, a plurality of slide supports, each of which can slide between a regular position and a withdrawal position, are arranged in parallel, an embossed tape roll, a sealing tape roll,
A tape cassette including a winding mechanism for superimposing the sealing tape on the embossed tape and winding the same in a roll shape is configured to be detachable from each of the slide supports at the pull-out position, and is at a regular position. slide
Of multiple tape cassettes mounted on the support
One selected is configured to perform a taping operation.
It is characterized in that it was. The taping device according to the present invention is, in short, a cassette of a material and a product tape take-up mechanism necessary for taping, which can be appropriately attached to and detached from a plurality of slide supports arranged in parallel. It was made. Focusing on one slide support and a tape cassette attached to the slide support, the slide support attached with the tape cassette in the operating state is positioned at a proper position and performs a predetermined taping operation. That is, while the embossed tape pulled out from the embossed tape roll is routed to the take-up reel while passing through a predetermined path, the sealing tape pulled out from the sealing tape roll is included in the embossed tape path,
At a part downstream of the part where the article is loaded in the conveying direction, the part is attached to the embossed tape by heat fusion or the like.
Then, the product tape to which this sealing tape is attached,
It is wound up on a reel. A mechanism for intermittently feeding the tape drawn from the embossed tape and a mechanism for winding the take-up reel are linked in a cassette, and are operated, for example, by an external intermittent push input. You can make it. When the embossed tape roll is completely consumed in one tape cassette, for example, it is optically detected that the end of the embossed tape has passed, and this detection information is sent to the article conveying mechanism, and the detected information is sent to the article conveying mechanism. The tape for sequentially storing the articles to be conveyed is switched to, for example, a tape cassette attached to an adjacent slide support. The tape cassette that has consumed the embossed tape roll is pulled out of the slide support supporting the embossed tape roll to the pull-out position, and is replaced with a new tape cassette. As described above, according to the taping device of the present invention, the materials necessary for taping and the winding mechanism are formed into cassettes, and a plurality of these are arranged in parallel. When finished, use the tape cassette next to this,
A continuous taping operation can be performed. Each of the tape cassettes can be replaced with a new one in a state where the slide support supporting the tape cassette is pulled out to the pull-out position. Therefore, continuous taping for an extremely long time can be performed, and taping of electronic parts and the like can be performed. , It is possible to carry out the shipping configuration very efficiently. Each of the tape cassettes is mounted on a slide support which can slide between a regular position and a withdrawal position, instead of being simply arranged in parallel. The tape cassette can be replaced as needed while keeping the interval between the tape cassettes to a minimum. Further, for the same reason that a plurality of tape cassettes are arranged in parallel, it is possible to quickly respond to a change in the production lot. That is, even if one production lot ends at a point in time when the embossed tape in the tape cassette is being consumed, and an article of a different production lot is subsequently conveyed, the production lot is not By switching tape cassettes, continuous taping can be performed. DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

The example of the tape cassette 1 attached to and detached from b.
In this tape cassette 1, a roll 9 of an embossed tape Ta, a roll 10 of a sealing tape Tb, and a take-up reel 11 of a product tape can be respectively attached to a chassis member 8 having a substantially vertical plate shape. ing. As shown in FIGS. 4 and 5, for example, the embossed tape Ta has a form in which product accommodating recesses a are formed at regular intervals in a resin tape material, and feed holes b are formed at regular intervals on one side. Can be used. The embossed tape Ta pulled out from the embossed tape roll 9 is guided by guide sprockets 13 engaging with guide pulleys 12 and feed holes b.
The take-up reel 11 is configured to be taken up via a horizontal traveling path. Then, the sealing tape Tb pulled out from the sealing tape roll 10 disposed above the horizontal running path of the embossed tape is superimposed on the embossed tape Ta via the guide pins 14, 14, and each slide The above-mentioned ironing mechanism 7 provided on the support is adapted to be thermally fused onto the embossed tape Ta. A guide plate 15 is integrally bent from the chassis member 8 so as to cover the upper surface of the horizontal traveling path of the embossed tape Ta. A predetermined electronic component P is sequentially loaded into each component accommodating recess a on the embossed tape Ta by a transport mechanism (not shown). The intermittent feeding of the embossed tape Ta is performed by rotating a feed sprocket indicated by reference numeral 13a in FIG. In this embodiment,

2 are installed. The tape cassette 1 is attached to the slide supports 2a, 2b,... In the pulled-out state, and is slid to a proper position to prepare for a taping operation. When one tape cassette 1 is selected, a push rod pushing mechanism (not shown) provided on the machine frame 4 pushes the push rod 19 to reciprocate the bell crank 18. Move. The push rod pushing mechanism is operated in conjunction with a transport mechanism (not shown) that transports the electronic component P from the pre-process apparatus. Electronic components transported by the transport mechanism are sequentially loaded into the respective recessed portions a of the embossed tape Ta that is intermittently fed through the window holes 16 of the guide plate 15. Then, the sealing tape Tb is superimposed on the upper surface of the embossed tape in which the electronic component is loaded in each of the accommodation recesses, and is thermally fused by the iron mechanism 7. Then, the product tape to which the sealing tape has been attached is wound up on the take-up reel 11. For example, when the take-up reel 11 becomes full, a taping cassette in which electronic components are to be loaded and taped is switched to an adjacent tape cassette. The fact that the take-up reel 11 has become full in this way can be performed by, for example, detecting that the take-up diameter on the reel has reached a predetermined diameter by an optical detection device. It can also be known by counting the total number of electronic components loaded in the. Further, even when the roll 9 of the embossed tape Ta is consumed, the taping operation can be continued by switching the cassette in which the electronic component is to be taped. The point at which the roll of the embossed tape has been consumed can be known, for example, by optically detecting that the rear end of the embossed tape has passed. Further, it is possible to quickly respond to a change in the production lot. In other words, although it is necessary to ship the reels wound on different reels for each production lot, even in a case where electronic components of different lots are continuously transported following one lot, the transport destination cassette may be changed. By switching, it is possible to respond quickly. Then, the take-up reel 11 is replaced,
Alternatively, replacement of the embossed tape roll 9 or the sealing tape roll 10 can be performed very quickly by pulling out the slide supports 2a, 2b. Further, according to the present invention, since the tape cassettes 1 as described above are not simply arranged side by side but supported by slide supports 2a, 2b,... The cassette can be replaced while the taping operation using the tape cassette on another slide support is continued while the slide support is being pulled out to the pull-out position where there is no tape. Further, the interval between the tape cassettes at the reference position can be minimized while presuming the cassette replacement, and the necessary process of the transport mechanism for transporting the electronic components on the tape can be performed. The transport cycle can be shortened as much as possible. As described above, according to the taping device of the present invention, the device can be operated even when the embossed tape is consumed, when the sealing tape is consumed, or when the take-up reel is full. A continuous taping operation can be performed without stopping. Further, even when the production lot is changed, it is possible to respond quickly, and as a result, the taping operation on the embossed tape such as an electronic component can be performed very efficiently. Of course, the scope of the present invention is not limited to the above embodiment. In short, the invention of the present application is such that a tape cassette equipped with each member or mechanism necessary for taping can be detachably attached to a plurality of parallel slide supports, and therefore, the specific shape of the slide support, the tape cassette Is not limited at all.
