Low-cost, high-quality products
Can greatly contribute in providing products. Further, the continuous conveying means (30C) has two sets.
(Intermittent) transfer mechanism (30C1 and 30C2)
Are alternately transported so that each jig 20 has the same transport level.
Transfer while maintaining a predetermined interval on the roller (33C)
Because it is a new structure that can be
Installation space compared to conveyor structures that require
Layout can be greatly reduced and the layout can be simplified.
Cost reduction can be achieved simply. Of the jig return conveyance means 30BR
The same applies to the case. According to the present invention, above the continuous processing tank,
A continuous transport rail fixedly disposed on the first level
Continuous transfer means that can continuously transfer the work held by the jig
And the first level above the pretreatment tank group and the
It has a front intermittent transport rail that can move up and down with the second level

Intermittent conveyance means that can intermittently transport the work
The first level above the treatment tank group and the first level above
Do you have a rear intermittent transport rail that can move up and down between two levels?
Is held by the jig when it is positioned on the second level.
Intermittent transfer means that can intermittently transfer the work
・ Fixedly arranged on the third level above the post-intermittent transfer rail
Jig return transfer rail and work transfer direction
A jig return that can return the jig received on the downstream side to the upstream side and transport it
And a transfer means, and the rear space positioned on the first level is provided.
Jig transferred from the transfer rail to the ascending rail
A lift that can be raised to a position where it can be delivered to the return transport rail
Means and the jig return from the transfer rail to the descending rail
Pre-intermittent transfer rail positioned on the first level
And a descent means that can be lowered to a position where it can be delivered to the
Flat surface installation space
Can be greatly reduced compared to the
Process can be performed continuously, and the factory
The cost can be reduced not only for equipment but also for buildings.
You. Further, both sides of each processing tank in plan view are returned by the return conveying means.
Is not occupied.
Not only can the work efficiency be improved, but also the work safety can be improved.
In particular, small workpieces (for example, printed wiring boards)
Providing low-cost, high-quality products for continuous processing
In that respect, it can make a significant contribution.
