Definitions
- the invention refers to a rack for supporting and moving concrete roof tiles with pallets into curing stations comprising lateral slide rails positioned in tiers and in pairs facing one another to carry the side edges of the pallets, wherein the lateral slide rails have opposing and mainly horizontal flanges, the outer borders of which connect to a step extending in upward direction.

This procedure is time-consuming and, due to a considerable need of manpower, involving very high labour cost, which makes it uneconomical. Also a large throughput capacity of the curing stations cannot be reached thereby.

Description
- The invention refers to a rack for supporting and moving concrete roof tiles with pallets into curing stations comprising lateral slide rails positioned in tiers and in pairs facing one another to carry the side edges of the pallets, wherein the lateral slide rails have opposing and mainly horizontal flanges, the outer borders of which connect to a step extending in upward direction.
- On a known rack for supporting flat tiles, especially glazed tiles, as disclosed in GB-A-601 880, the tiles are supported on ledges formed on the inner faces of bars located in spaced parallel relation upon a base member. The ledges are provided with a stepped formation, whereby the tiles are spaced away from the face of the bars to prevent possible adhesion by the glaze of the tiles. The ledges are only suitable for supporting normal tiles. Special roof tiles, as for instance ridge tiles or verge tiles, cannot be placed on the known rack; up to now, they were transported from a conveyor belt into the curing station by hand and placed there on special supports. After curing it was necessary to remove these special tiles from the curing station again by hand and to put them on de-palleting belts. This procedure is time-consuming and, due to a considerable need of manpower, involving very high labour cost, which makes it uneconomical. Also a large throughput capacity of the curing stations cannot be reached thereby.
- The object of the invention is to provide a solution by which a rack of the aforementioned type is designed in such a way that also special tiles of different dimensions, in particular narrower ridge tiles and verge tiles with a side overhang, can be placed thereon.
- For a rack of the aforementioned type, this problem is solved according to the invention in that the step of the one slide rail has an upper side descending from the edge of the step at an angle of inclination of 5 to 25° against a horizontal plane in outward direction and the step of the other slide rail has an upper side ascending, at least in the area connecting to the edge of the step, at about the same angle of inclination in outward direction.
- Due to this invention, practically all existing types of concrete roof tiles can be placed on the rack, no matter whether normal roof tiles or special tiles, as for instance ridge tiles or verge tiles, are involved, because the profile of the lateral slide rails according to the invention makes it possible to place thereon roof tiles of different width as well as shape and to achieve a reliable support.
- For a very often used type of verge tile pallets, an accurate and reliable support is achieved if the angle of inclination of the upper side of the one step and of the area of the upper side of the other step is 15°.
- An embodiment of the invention will now be described with reference to the accompanying drawings in rfniini
- Figure 1 is an end elevation of a rack according to the invention;
- Figure 2 is a side elevation of the rack shown in Figure 1 on a reduced scale;
- Figure 3 is a cross-sectional view on an enlarged scale of one of the slide rails positioned on the left-hand side of the rack shown in Figure 1;
- Figure 4 is a cross-sectional view on the same scale as in Figure 3 of one of the slide rails positioned on the right-hand side of the rack shown in Figure 1;
- Figures 5 and 6 are views of the rack shown in Figure 1 with loading examples.
- As shown in Figure 2, the rack generally designated 1 has three supporting
frames 2 which, according to Figure 1, consist in each case of twolateral frame parts 3, abottom frame part 4, and ahead frame part 5. On thelateral frame parts 3,slide rails - As not shown, the feeding of the
rack 1 with the concrete roof tiles on pallets is preferably carried out by one or, according to DE-PS 19 45 419, by several conveyor belts positioned one upon the other. At the same time, theslide rail pairs entrance area 8. Therack 1 is additionally provided withsupports 9 which permit an automatic moving. - The
slide rail 6 shown in Figure 3 in a cross-sectional view consists of a multiply bent off sheet metal part which has afastening flange 10 which connects to asection 11 extending horizontally. By bending back the sheet metal from the inner edge of thesection 11, a doubling is produced whereby aflange 12 is formed which, after about one third of the width of the section, connects to astep 13. The front side of thestep 13 extends from the outer border of theflange 12 over a steeplyascending area 14 to avertical area 15 which terminates at anedge 16 of the step. Thestep 13 has anupper side 17 descending from theedge 16 of the step at an angle of inclination a of about 15° against thehorizontal plane 18 in outward direction and extending then to another fasteningflange 19. - The
slide rail 7 shown in Figure 4 on the same scale as in Figure 3 consists like theslide rail 6 of a multiply bent off sheet metal part and has also respective fastening flanges 10', 19', a section 11' extending horizontally, a flange 12' formed by doubling, and a step 13'. Unlike theslide rail 6, the step 13' of theslide rail 7 has astiffening rib 20 in its lower part which connects to the vertical area 15'. Besides, only an area 17' of the upper side connecting to the edge 16' of the step extends at the same angle of inclination a of about 15° against thehorizontal plane 18, as shown in Figure 3, whereas thefollowing area 21 extends horizontally and is connected over a steeplyascending area 22 with the other fastening flange 19'. - As can be seen, in particular from Figures 5 and 6 showing the loading examples, practically all existing types of concrete roof tiles can be placed with their pallets on the
slide rails flanges 12, 12' make the placing of thepallets 23 for ridge tiles 24 (lower half of Figure 5) possible, and thesteps 13, 13' permit the placing of thepallets 25a-25e for normalconcrete roof tiles 26a-26e with different profiles, as also shown in Figure 5. - The inclined
upper side 17 of theslide rail 6 and the correspondingly inclined area 17' of the upper side of theslide rail 7 make an accurate positioning of thepallets 27a-27e forverge tiles 28a-28e with different profiles possible, as shown in Figure 6. The pallets are provided with a supportingshoulder 29a-29e, which rests firmly against therespective slide rail 6 due to the inclinedupper side 17 and area 17'.
