[Industrial applications]
The present invention relates to a taping method in which electronic components such as chip resistors or transistors are filled one by one into each of the component storage portions formed in a hoop-shaped carrier tape at regular intervals. The present invention relates to a device for refilling an electronic component into an empty component storage unit that cannot be loaded.
[0002]
[Prior art]
In general, taping apparatuses for filling electronic components one by one into each of the component storage portions of a carrier tape include, for example, JP-A-63-155712, JP-A-63-317408, and JP-A-Heisei 63-317408. As described in Japanese Patent Application Publication No. 171231/1995, there are various types. However, in these taping apparatuses, if a filling error that electronic components cannot be loaded occurs, a part of the carrier tape is stored. When the part is empty, when the electronic components are automatically loaded onto the printed circuit board or the like from the carrier tape, lack of the electronic components on the printed circuit board is caused.
[0003]
Therefore, conventionally, a sensor for detecting whether or not the electronic component is filled in the carrier tape is provided in a carrier tape transfer path, and when the electronic component is detected in an empty state by the sensor, the filling operation is performed one time. sealed Dantoma, in this stop state, for an empty part housing unit in the carrier tape, the worker has to be replenished filled with electronic components.

You. "
Was configured.
[0007]
[Operation]
In this configuration, each of the component storage portions of the carrier tape is sequentially filled with the electronic component at the location of the filling means by the filling means. During this filling, when the electronic component is filled in each component storage, but continues the filling of the, at the location of the filling means, the filling mistake to component storage of electronic components occurs, the component housing state without electronic components in parts, when it is detected by the presence or absence sensors that positioned in front of the filling means, on the basis of this signal, to the back movement at the reciprocating mechanism of horizontal transfer means pixels with respect to the carrier tape the Rukoto, empty part housing unit located on the horizontal transport means of the carrier tape Ru is transported back in the direction of the transport direction and opposite. In this case, since the portion of the carrier tape located on the upstream side of the horizontal transfer means is held in a loose state in the space formed on the upstream side of the horizontal transfer means in the transport path, for example, Even if the upstream hoop portion of the carrier tape, the reel for feeding, or the feeding mechanism is rotated in the reverse direction and the carrier tape is not rewound, the empty component storage section of the carrier tape has a substantially horizontal posture. It can be reliably positioned at the location of the filling means as it is. Therefore , electronic components can be reliably refilled into the empty component storage portion by the filling means.
[0008]
When the replenishment and filling of the empty component storage portion with the electronic components is completed, the carrier tape is returned to the original state before the return transfer by the reciprocating mechanism for the horizontal transfer means, thereby storing each component in the carrier tape. The filling of the electronic parts into the parts by the filling means is continued.
[0009]
Further, in case of returning to the original state from the case and the return transport to transfer back the carrier tape, the portion located on the horizontal transport means of the carrier tape, the substantially horizontal posture by the horizontal transfer means Since the carrier tape can be held as it is, during the return transfer and the return transfer of the carrier tape, it is possible to reliably prevent the electronic components that would have filled the respective component storage units from jumping out of the component storage units.
[0010]
【The invention's effect】
As described above, the present invention refills electronic components into each of the component storage portions of the carrier tape that is empty due to a filling error or the like by filling electronic components into each of the component storage portions of the carrier tape. This is done by means . This ensures that, because it is possible to achieve automation of the replenishment filling of electronic components with respect to the empty part housing unit, has the advantage of being able to greatly improve the operating rate, reduce the cost.
[0011]
【Example】
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
In the drawing, reference numeral 1 denotes a hoop-shaped carrier tape formed by forming the component storage portions 1a at regular intervals along the longitudinal direction. The carrier tape 1 is rotated by a pair of upper and lower feed wheels 2a, 2b. Are transported intermittently along the longitudinal direction at the pitch intervals of the component storage portions 1a.
[0013]
Filling means that fills each of the component storage portions 1a of the carrier tape 1 with the electronic component 3 one by one at a position forward of the pair of feed wheels 2a and 2b along the transport direction of the carrier tape 1. 4 is arranged, in the region of the front from the charging means 4 by appropriate distance L ₁ along the longitudinal direction of the carrier tape 1, detects the presence or absence of the electronic component 3 in each component accommodating section 1a in the carrier tape 1 electronic component detecting sensor 5 is arranged in the region of the front from the electronic component detecting sensor 5 by appropriate distance L ₂ along the longitudinal direction of the carrier tape 1, each component storage 1a in the carrier tape 1 to front and back sensor 6 which detects the front and back of the electronic component 3 of the can is disposed, further, as appropriate distance L along from the front and back sensor 6 in the longitudinal direction of the carrier tape 1 Only in front of the site, the the front and back sensor 6 detects the electronic component 3 that is filled in a state inside out the component housing section 1a, component storage the electronic component 3 inside out on the basis of the detection signal by the vacuum suction A removing means 7 for removing from 1a is provided.
[0014]
Then, the carrier tape 1 is transferred in a substantially horizontal posture with the respective component storage portions 1a facing upward to a portion between the filling means 4 and the removing means 7 in the transport path of the carrier tape 1. The horizontal transfer means 8 is arranged so as to reciprocate along the transfer direction of the carrier tape 1, and the horizontal transfer means 8 is moved by a reciprocating mechanism (not shown) provided on the horizontal transfer means 8. , as well as configured above movement distance L ₁ only back in the transport direction opposite to the direction of the carrier tape 1 from the filling means 4 until detecting sensor 5, the distance L _{4 (L 4} until removal means 7 from the filling means 4 = L ₁ + L ₂ + L ₃ ) so as to move backward in the direction opposite to the transport direction of the carrier tape 1. When the horizontal transfer means 8 is moved backward by the reciprocating mechanism (not shown), the empty component storage portion 1a of the carrier tape 1 located on the horizontal transfer means 8 is moved in a direction opposite to the transfer direction. The portion of the carrier tape 1 which is transported back and located on the upstream side of the horizontal transport means 8 is held loose in the space between the horizontal transport means 8 and the feed wheels 2a, 2b. (See FIG. 1).
[0015]
In this configuration, each of the component storage portions 1a of the carrier tape 1 that is intermittently transferred is filled with the electronic component 3 at the location of the filling means 4 by the filling means 4 in sequence.
[0016]
At this time, when the electronic components 3 are filled in the respective component storage portions 1a, the above-described charging is continued. However, at the location of the charging means 4, a filling error of the electronic components 3 into the component storage portion 1a occurs. Then, when the absence of electronic components in the component storage section is detected by the presence / absence sensor 5, on the basis of this signal, the horizontal transfer means 8 for the carrier tape 1 is moved by the reciprocating mechanism to the dashed line in FIG. as shown in, it is back moved in the transport direction opposite to the direction of only the carrier tape 1 distance L ₁ from the filling means 4 until detecting sensor 5.
[0017]
Then, by the back movement of the horizontal transfer means 8, the empty part housing unit 1a which is located on the horizontal transfer means 8 of the carrier tape 1, Ru is transferred back to the transfer direction and the reverse direction. In this definitive horizontal transfer unit 8 back movement, the upstream portion of the horizontal transfer means 8 of the carrier tape 1, wheel 2a and the feed horizontal transfer means 8, into the space between the 2b, a point in FIG. 1 since the slack absorbing as indicated by a chain line, not or rewind the carrier tape 1 with the upstream side of the hoop portion in the carrier tape 1 (not shown) or the two feed wheels 2a, rotated in reverse 2b, etc. be an empty part housing unit 1a on the horizontal transfer means 8 of the carrier tape 1 can be located reliably position the filling means 4 remain substantially horizontal posture. Therefore , the electronic component 3 can be reliably refilled by the filling means 4 into the empty component storage portion 1a .
[0018]
When the replenishment and filling of the electronic component 3 into the empty component storage portion is completed, the carrier tape 1 is returned to the original state before the return transfer by the reciprocating mechanism for the horizontal transfer means 8, and thereby the carrier tape 1 is returned. Then, the filling of the electronic components 3 by the filling means 4 in each of the component storage portions 1a is continued.
[0019]
When the front and back sensors 6 detect that the electronic components 3 filled in the respective component storage portions 1a of the carrier tape 1 are turned upside down, the electronic components 3 are turned over by the front and back sensors 6. the removing means 7 at the site of the front by appropriate distance L _3, it is removed from the component storage 1a. When the removal is completed, the horizontal transfer means 8 for the carrier tape 1 is moved by the reciprocating mechanism by a distance L ₄ from the filling means 4 to the removal means 7 as shown by a two-dot chain line in FIG. 1 (in this case as well, the carrier tape 1 is placed in the space between the horizontal transfer means 8 and the feed wheels 2a and 2b, as indicated by a two-dot chain line in FIG. 1). Without having to reversely rotate the upstream hoop portion of the carrier tape 1 or the two feed wheels 2a, 2b, etc. to rewind the carrier tape 1. component housing portion 1a, since it is possible to position the reliable location of the filling means 4 remain substantially horizontal posture, the electronic component 3 against the empty part housing unit 1a, the The refilling can be reliably performed by the refilling means 4. When the refilling is completed, the carrier tape 1 is returned to the original state before the return transfer by the reciprocating mechanism for the horizontal transfer means 8, and the carrier tape 1 is refilled. Then, the filling of the electronic components 3 by the filling means 4 in each of the component storage portions 1a is continued.
