Abstract
A roll edging machine for folding up a flange along the longitudinal edges of a sheet metal panel comprises two sets (16; 17) of pairs (18; 19) of driven forming rolls (18A, 18B; 19A, 19B) positioned at opposite longitudinal edges of a horizontal panel feed table (10). Each pair (18; 19) of forming rolls comprises an upper forming roll (18A; 19A) and a lower forming roll (18B; 19B), and in each set of forming roll pairs the axes (24, 26; 25, 27) of rotation of the forming rolls are parallel and contained in a pair of parallel planes including an angle of about 45o with the feed table (10). The planes containing the axes (24, 26) of one set intersect the planes containing the axes (25, 27) of the other set along parallel horizontal lines below the feed table (10).
Description
ROLL EDGING MACHINE
This invention relates to a roll edging machine for ** folding up a flange along at least one of two opposite
,. edges of a sheet metal panel.
5 In the art of metal roofing, it is known to form sheet metal panels with upstanding flanges along opposite longitudinal edges preparatory to the steps of laying the panels side by side on a supporting roof structure and joining them together by seaming the abutting flanges of 10 contiguous panels.
An object of the present invention is to provide an edging machine for forming upstanding flanges on sheet metal roof panels which is of compact and lightweight construction so that the roofer can readily take the 15 machine with him to the building to be provided with sheet metal roofing.
Briefly, the invention comprises an edging machine . which has at least one set of aligned pairs of rotatable forming rolls at a longitudinal edge of a horizontal panel 20 feed table. Each pair of forming rolls comprises an upper forming roll and a lower forming roll. The axes of rotation of all forming rolls of the set or each set are parallel and contained in vertically spaced planes including an acute angle with the feed table. Thanks to the inclined 25 axes, the forming rolls may have relatively small dimen¬ sions so that the entire machine, or at least the part of the machine comprising the set or sets of forming roll pairs, can be compact and lightweight.
Other objects, advantages and features of the inven- „, 30 tion will be understood from the following detailed description of the preferred embodiment with reference to the accompanying drawings. Q FIG. 1 is a diagrammatic plan view of an edging machine embodying the invention; 35 FIG. 2 is a view, partially in cross-section on line II-II of FIG. 1, of the machine;
FIG. 3 shows the cross-sectional shape of a roof panel formed with longitudinal upstanding flanges in the machine
FIG. 4 comprises a series of subfigures designated I to VI and showing the successive pairs of forming rolls forming one of the flanges of the panel shown in FIG. 3; FIG. 5 similarly comprises a series of subfigures designated I to IV and showing successive pairs of forming rolls forming the other flange of the panel shown in FIG. 3.
As shown in FIGS. 1 and 2, the edging machine of the invention is used for simultaneous forming of initially flat sheet metal roof panels into the cross-sectional shape shown in FIG. 3. The finished flanged panels comprise a flat intermediate portion A, an "outer" flange B and an "inner" flange C (the terms "inner" and "outer" as used herein refer to the relative positions of the abutting flanges of contiguous panels laid on the supporting structure) .
The machine shown in the drawings comprises a horizon¬ tal panel feed table 10 defining a horizontal panel feed plane 10A. The feed table 10 comprises an infeed section 11 formed of a flat plate having parallel lateral guides
12 and 13 adjustably spaced apart by a distance correspond¬ ing to the width of the sheet metal panel to be formed with flanges. The feed table also comprises an edging section 14 including a number of horizontal bars 14A mounted on a frame 15. Two of the bars 14A extend in the feed direction past the frame 15 to provide support for . the flanged panel as it leaves the edging section 14. Two sets 16 and 17 of pairs of forming rolls are supported on the frame 15 along respective longitudinal sides of the edging section 14. The set 16 comprises six pairs 18 of forming rolls serving to form the "outer" flange B, while the set 17 comprises four pairs 19 serving to form the "inner" flange C.
Each pair 18, 19 comprises an upper and a lower forming roll 18A, 18B and 19A, 19B, respectively, defining a nip for the panel margin approximately level with the feed plane 10A. The rolls are secured to respective ones of a pair of parallel shafts 20, 21 which are rotatably journalled in a support 22, 23 on the frame 15. The axes
of rotation of the two forming rolls 18A, 18B and 19A, 19B of each pair are parallel and contained in a common vertical plane extending transversely across the feed • table 10. In each set 16, 17 the axes of rotation of the upper rolls 18A, 19A are contained in a common plane 24, 25, respectively, including an acute angle 0 with the feed plane 10A. Similarly, the axes of rotation of the lower rolls 18B, 19B of each s*et 16, 17, respectively, are contained in a common plane 26, 27 parallel to the plane 24, 25, respectively, of the axes of the upper rolls and thus including the same acute angle α with the feed plane 10A. As shown in FIG. 2, the parallel and vertically spaced planes 24, 26 intersect the parallel and vertically spaced planes 25, 27 along horizontal lines below the feed plane 10A. The angle α is 35°-55°, preferably about 45°. An electric motor 28 common to both sets 16, 17 positively drives one or both forming rolls of each pair 18, 19 through an angled gear 29 coupled to the lower forming roll 18B of one- of the roll pairs 18 of the set 16, namely, the roll pair positioned at the infeed end of the edging section 14. The shaft 20 of this roller 18B is connected through universal joints 30 and a telescopic shaft 31 to the shaft 21 of the lower forming roll 19B of that pair 19 of the set 17 which is positioned at the infeed end of the edging section 14. The other forming roll pairs are driven from the just-mentioned pairs through gear transmissions 32, 33.
