Place 81.

Note that this mechanism 181 has the same structure as the soldering object pusher side 161 on the intake side, so a description thereof will be omitted. Also, this action on the take-out side is as follows:
71, the printed circuit board P is supported by the soldering object receivers 126 and 127 on the extraction side at a certain lowering level.
is pressed horizontally toward a certain level of the container 57 on the extraction side. Next, the overall operation will be explained.

A worker picks up the storage body 5 in which printed circuit boards P are stored in each stage.
6 is the stacking base 1 of the storage body transverse feeding mechanism 111 on the intake side.
13 and empty containers 57 are set on the transverse feed base 113 of the accommodation volume feeding mechanism 112 on the extraction side.
, 112 to the vertical feeding mechanisms 75, 76 for the containers on the intake side and the extraction side, and are positioned and fixed on the vertical feeding bases 82 of these mechanisms 75, 76.

On the intake side, the container 66 is initially positioned below, and the soldering object pusher 161 pushes out the uppermost printed circuit board P in the container 56 from the container 56 to a certain lower level. The soldering object receiver 124, 12
5, this printed circuit board P is raised by the receivers 124 and 125 to the level of the holding claws 9 of the holder 6, and at this level is positioned at a fixed position by the holder positioning mechanism 31 and the holding claw opening/closing mechanism. 42 and is held by the holding claws 9 waiting in an open state, conveyed by the soldering line conveyor, and soldered.

Note that on this intake side, the container 56 is intermittently raised by the container vertical transport mechanism 75, and is discharged from the container 56 in the order of printed circuit boards P in the upper stage to printed circuit boards P in the lower stage. On the extraction side, once the holder 6 is positioned at a certain position by the holder positioning mechanism 31, the soldering object receivers 126 and 127 on both sides that have risen to the level of the holding claws 9 are closed, and the other side of the printed circuit board P is closed. After that, the holding claws 9 are opened by the holding claw opening/closing mechanism 42, and the printed circuit board P, which has been lowered to a certain lowering level by the receivers 26 and 127, is moved to the soldering object pushing base 181 at the same level. According to the above receiver 12
6, 127 and stored in each stage of the container 57 on the extraction side.

Note that on this take-out side, the container 57 is initially located at the top, and each time a printed circuit board P is inserted, it is sequentially moved downward by the container vertical feed mechanism 76, and the printed circuit board P is located at the bottom of this container 57. They are inserted in order from the row above. In addition, since the heavy containers 56 and 57 with printed circuit boards P stored in all stages are located at the bottom on both the input side and the extraction side, the transfer of the input side is difficult. It is easy for the operator to supply the containers 56 to the base 113 and to take out the containers 57 from the vertical feed base 82 on the take-out side. 0 In addition, the motors and air cylinders of each mechanism are controlled in sequence using limit switches, etc.

As described above, according to the present invention, in the soldering material intake section and the soldering material removal section, the housing body that accommodates the soldering material in a plurality of stages in the vertical direction at intervals is connected to the soldering line. The container is placed on the side of the conveyor, and the container is intermittently transferred vertically at the storage interval of the soldering objects by the container vertical feeding mechanism, so that the holding claw of the holder of the soldering line conveyor stops at the stop position. Arrange the soldering object receptacle that moves downward and up and down, and place the soldering object receptacle on the intake side at the lower level opposite to the receptacle on the intake side in the above-mentioned soldering object intake part. Place the side of the soldering object pusher in the installation example at the same descending level on the side of Since the side of the pusher for soldering objects on the extraction side is placed at the same descending level on the opposite side of the container, it automatically moves multiple objects to be soldered inside the container to the lower part of the holding claw of the holder. It is possible to carry the soldering object sequentially to a certain level and then raise it and hold it in the holding claw, and automatically lower the object to be soldered which has been released from the holding claw to a certain level and then move it to the side storage body. It can be carried out sequentially, and the work of attaching and removing objects to be soldered to and from the soldering line conveyor can be carried out labor-saving and highly efficiently without impairing the working speed of the soldering line.

This also made it possible to achieve high efficiency in soldering work.
