摘要： An electronic parts mounting method in which chips in a plurality of parts feeders are picked up respectively by at least three nozzles, and a lowered mounting efficiency is avoided when any of the nozzles becomes bad, thereby mounting the chips on a board with a good operation efficiency. In a normal condition, the chips in the parts feeders are simultaneously picked up respectively by the first, second and third nozzles, and are transferred to and mounted on the board. When any of the three nozzles becomes bad, the mounting of the chips by this bad nozzle is stopped while the mounting of the chips by the other normal nozzles is effected as scheduled in a program, and thereafter those chips scheduled to be mounted by the bad nozzle are mounted by the normal nozzles. Therefore, the number of the pick-up operations is reduced as much as possible, so that the mounting efficiency can be enhanced.

摘要： There is disclosed an electronic parts mounting method in which it is possible to avoid a pick-up mistake for electronic parts (chips) in simultaneously picking up the chips respectively stored in juxtaposed parts feeders by a plurality of nozzles provided to a transfer head. Nozzle position data of first, second and third nozzles 9a, 9b and 9c are beforehand obtained by a first camera, and pick-up positions of the chips in parts feeders 4 are obtained by a second camera. After picking up respectively the chips in the parts feeders 4 by the nozzles 9a to 9c it is judged whether or not there would be caused the pick-up mistake. When it is judged there is caused no pick-up mistake, a transfer head is moved to a position above a board and each of the chips is mounted to the board. When it is judged there is caused any pick-up mistake, a pick-up mistake rate of any of the parts feeders in which the pick-up mistake occurs, is updated and each of the chips is picked up again by the nozzle which caused the pick-up mistake.
摘要翻译：公开了一种电子部件安装方法，其中可以避免电子部件（芯片）通过设置在转印头上的多个喷嘴同时拾取分离存储在并置部件进给器中的碎屑的拾取错误。通过第一照相机预先获得第一，第二和第三喷嘴9a，9b和9c的喷嘴位置数据，并且通过第二照相机获得部件供给器4中的芯片的拾取位置。在通过喷嘴9a至9c分别拾取部件进给器4中的切屑之后，判断是否会引起拾取错误。当判断为没有引起错误时，将转印头移动到板上方的位置，并将每个芯片安装到板上。当判断出有引起错误的情况下，发生拾取错误的任何零件进给器的拾取错误率被更新，并且通过喷嘴再次拾取每个切屑拿起错误。

摘要： A first camera detects a positional relationship among first, second and third nozzles. A second camera detects pick-up positions of chips in parts feeders. Tolerance zones for the respective chips are determined, within which the nozzle can pick up the chip. When one of nozzles is placed in the corresponding pick-up position, it is judged whether or not other nozzles are located within the corresponding tolerance zones, respectively. If the judgment result is "YES", the nozzles pick up the chips simultaneously , and if this result is "NO", the nozzles pick up the chips separately.
摘要翻译：第一相机检测第一，第二和第三喷嘴之间的位置关系。第二台相机检测零件进给器中的芯片的拾取位置。确定各个芯片的公差区域，其中喷嘴可以拾取芯片。当其中一个喷嘴被放置在相应的拾取位置时，判断其他喷嘴是否分别位于相应的公差区域内。如果判断结果为“是”，则喷嘴同时拾取芯片，如果该结果为“否”，则喷嘴分别取出芯片。

摘要： For use with a fork lift truck having a pair of vertically spaced apart forks which are raised or lowered in union, apparatus for exchanging a loaded or unloaded pallet with an unloaded or loaded pallet, respectively, by back and forth movement of the fork lift truck and by vertical movement of the forks. The apparatus comprises a pallet supporting member which is biased under the force of a spring so as to move to an extended pallet supporting position from a retracted position out of a path of pallets carried by the forks; a lever which is located at a position higher than said pallet supporting member; and a connecting member which is formed with elongated slots into which are fitted said lever and said pallet supporting member, said connecting member being raised by upward movement of an unloaded pallet engaging the lever to incline it upwardly, the connecting member retracting the pallet supporting member and latching it. When said lever is inclined downwardly by downward movement of a loaded pallet, the pallet supporting member is unlatched and returned to said pallet supporting position. When the forks go down further, the loaded pallet which was on the upper fork of the truck is left on the supporting member and only an unloaded pallet is now on the lower fork of the truck.
