Lubricant spraying apparatus and method for treating inner surfaces of insertion and assembly aids in a packing station

Lubricant spraying system 1 for treatment of the inner surfaces of insertion and assembly aids with through-openings, for an inboxing of battery plate packs (17) into suitably sized battery containers (18) in a boxing station, characterized in that a lubricant spraying system (1) equipped with an exhaust system (19) consists of a a first spray station (2), second spray station (3), a mounting station (4) arranged between these, between which an adjusting and sliding frame (5) constructed as a hollow body is arranged so as to be movable in a horizontally directed manner, wherein the spray stations (2, 3) each being equipped with at least one stationarily positioned and pivotably arranged spray head (11) for lubricant spraying, and at least one vertically directed infeed rod (16) equipped with load cells and capable of vertical lifting movement being arranged on a movable upper part of the mounting station (4), in that there is a plurality of horizontal functional levels in the lubricant spraying system (1), wherein

• on an upper feed level (6) over a feed section, battery plate packs (17) positioned, sorted and each fixed by a clamping jaw device is moved by a linear drive into a middle position in the mounting station (4),
• arranged on an upper working level (7) are the spray head of each of the first spray station (2) and the second spray station (3),
• on a middle working level (8), the adjusting and sliding frames (5) are arranged, designed in the form of at least two single frames or one double frame each with square inner openings each, longitudinally movable to and fro in coordinated cycle times between the spraying stations (2, 3) and the mounting station (4) in a linear direction, and wherein
• on a lower working level (9) the lowered infeed rod (16) is arranged, which abuts on the end faces of the battery plate packs (13) via the clamping jaw device and, during a lowering insertion and sliding movement of which, passing through the adjusting and sliding frame (5) arranged on the middle working level (8), is temporarily positioned into the empty battery containers (18) transferred to and arranged on the lower working level (9) and, after the battery plate packs (17) have been boxed into the battery containers (18), is moved back from this position to the middle working level.
