[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parts taping device for continuously accommodating electronic components for surface mounting (hereinafter referred to as "parts") in accommodating holes of a carrier tape, In particular, for one part conveying line, first and second carrier tape supplying means are provided on both sides of the part conveying line, and the parts are moved from the part take-out position of the part conveying line to the first and second parts by the part transferring means.
The present invention relates to a parts taping device adapted to alternately transfer parts one by one to a parts transfer / accommodation position of one of the carrier tape supplying means.

2. Description of the Related Art As is well known, the work of mounting parts such as transistors and ICs on a printed circuit board is automatically performed by a machine called a mounting machine. In order to mount the parts on the printed circuit board by the mounting machine, it is necessary to supply the parts to the mounting machine in the same direction at a predetermined interval. Carrier tapes are used for this purpose. The carrier tape is a long tape, and accommodation holes for arranging and accommodating the parts in the same direction at predetermined intervals are provided along the length direction, and after the parts are inserted into the accommodating holes, the parts are The housing hole is closed by a cover tape so as not to fall off, and the carrier tape loaded with parts is wound on a reel and shipped. At the printed circuit board assembly site, the reel is attached to the mounting machine, the reel is rotated by a step motor, the carrier tape is unwound from the reel, and parts are supplied to the mounting machine.

The operation of loading parts into the accommodation holes of the carrier tape is automatically performed by a machine (hereinafter referred to as a parts taping device). The parts taping device unwinds a carrier tape not loaded with parts from a supply reel and supplies it to a parts storage position, stores the parts in a storage hole of the carrier tape at the parts storage position, and passes the carrier tape passing through the parts storage position. The accommodation hole is closed by a cover tape, and the carrier tape closed by the cover tape is wound by a winding reel.

[0004]

By the way, the conventional parts taping apparatus has a problem that the efficiency of the parts manufacturing machine or the parts supplying machine is lowered when it is used by connecting to the parts manufacturing machine or the parts supplying machine. When the carrier tape wound on the supply reel is exhausted, the parts taping device must be stopped to replace the supply reel and the take-up reel. While replacing the supply reel and the take-up reel, the parts supplied from the parts manufacturing machine or the parts supply machine are stored in the buffer, and when the replacement of the supply reel and the take-up reel is completed and the parts taping device is driven, The parts stored in the buffer are processed. At this time,
In order to recover the storage space of the buffer, the loading speed of the parts by the parts taping device must be higher than the speed at which the parts are supplied from the parts manufacturing machine or the parts feeder, but the loading speed of the parts taping device should be much higher. I couldn't do that and had to slow down the parts maker or parts feeder.

In order to solve this problem, a method has been proposed in which parts are processed by a parts taping device arranged at a position distant from a parts manufacturing machine or a parts feeder. According to this method, parts are once loaded in a tray or a stick magazine, the tray or stick magazine is attached to a parts taping device, and the parts are supplied to the parts taping device. With this method, the efficiency of the parts manufacturing machine or the parts feeder does not decrease, but the trays and stick magazines with the parts loaded must be carried to the parts taping device and mounted on the parts taping device, which takes time and effort. There was a problem. There is also a problem that equipment costs rise because parts such as trays and stick magazines and machines for storing parts in the trays and stick magazines are required.

Therefore, it is an object of the present invention to provide a parts taping device which can be used by connecting to a parts manufacturing machine or a parts feeder, and which does not reduce the efficiency thereof.

[0007]

In order to achieve the above-mentioned object, the present invention specifically conveys a part along one part conveying line, and a part take-out position provided in the part conveying line. And a carrier tape which is provided on both sides of the parts conveying means for sequentially supplying the parts and along the parts conveying line in the parts conveying means and which is provided with a large number of parts accommodating holes at regular intervals. First and second carrier tape feeding means for feeding along the carrier tape feeding line and feeding and feeding the parts holding holes of the carrier tape to the parts feeding and holding position sequentially, and the parts fed to the parts taking-out position are sucked. From the position where the parts are picked up, one of the first and second carrier tape supplying means transfers and collects the parts. Position to a part transfer means for transferring the part on one side at a time alternately, and parts supply amount detection means, wherein outputs either one of the detection signal by detecting a predetermined part supply amount with respect to the carrier tape,
Parts taping comprising control means for switching the parts transfer direction of the parts transfer means from one of the parts transfer housing positions to the other part transfer housing position side in response to a detection signal from the parts supply amount detecting means. It constitutes a device.

[0008]

According to the present invention, first, the first carrier tape supply means is driven, and the carrier tape is unwound from the first supply reel and supplied to the first part transfer / accommodation position. The parts supplied from the parts manufacturing machine or the parts feeder are conveyed by the parts conveying means and positioned at the parts take-out position. The positioned parts are moved by the parts transfer means and are housed in the housing holes of the carrier tape at the first parts transportation housing position. The accommodation hole of the carrier tape which has passed the first parts transfer accommodation position is closed by the cover tape supplied from the first taping means, and the carrier tape whose accommodation hole is closed is taken up by the first take-up reel. .

When the parts of the first carrier tape supplying means have been loaded into the carrier tape, the second carrier tape supplying means is driven, and the carrier tape is unwound from the second supply reel to the second carrier tape. It is supplied to the parts transfer storage position. Second by means of parts transfer
The parts are accommodated in the accommodation holes of the carrier tape at the parts transfer accommodating position, and the accommodating holes of the carrier tape that have passed through the second parts transfer accommodating position are closed by the cover tape supplied from the second taping means. The carrier tape which is closed is wound up by the second winding reel. The first supply reel and the first take-up reel can be replaced with new ones while the parts are loaded on the carrier tape of the second carrier tape supply means.

When the loading of the parts on the carrier tape by the second carrier tape feeding means is completed, the first carrier tape feeding means is driven, and the loading of the parts on the carrier tape by the first carrier tape feeding means is started. To be done. The second supply reel and the second take-up reel of the second carrier tape supply means can be replaced with new ones while the parts are loaded in the carrier tape of the first carrier tape supply means. By repeating the above operation, the parts supplied from the parts manufacturing machine or the parts supply machine can be loaded into the carrier tape without delay.
