Supporting structure for a sliding rail

Abstract

Supporting structure for sliding rail that uses one or more identical modules, stacked longitudinally and supported on the beams of the conventional compact palletisation facility, on which the tracks for the chains of the sliding rail are subsequently mounted, each of these modules including, in turn, a quadrangular mesh supported on several ribs that may be fixed or telescopic, and which has, on its upper part, supporting rods for the rails for the chain. The supporting structure for sliding rail that is presented affords the main advantage of enabling any existing compact drive-in palletisation structure to be used and adapted to operate with flow-rail sliding rails or similar, dispensing with the need for custom adaptations, as well as achieving greater rigidity, better inner fitting, greater resistance to deformation and smoother operation of the sliding rail.

PREFERRED EMBODIMENT OF THE INVENTION

(14) The conformation and characteristics of the invention can be better understood in the following description that relates to the attached figures.

(15) As can be seen in FIG. 1, the supporting structure for sliding rail is shown, indicating a mesh (1), with a quadrangular format, supported on several ribs (2), which has supporting rods (3) for the rails (15) on its upper part, on which subsequently a chain (16) will slide, the said rods (3) being arranged perpendicularly to the ribs and distributed in pairs.

(16) The ribs (2) are fixed-length ribs (2a) or telescopic ribs (2b) of adjustable length, to adapt better to any type of conventional compact palletisation facility,

(17) FIG. 2 shows the supporting structure for sliding rail in perspective, indicating the mesh (1), with a quadrangular format, supported on several ribs (2), which has supporting rods (3) for the rails (15) on its upper part, on which subsequently a chain (16) will slide, the said supporting rods (3) being arranged perpendicularly to the ribs and distributed in pairs.

(18) FIG. 3 shows the fixed-length ribs (2a), formed as a single piece, comprising a central element (4) of a notably greater length than the rest of the dimensions, finished at both ends with flat terminations (5). These flat terminations (5) have, in turn, several emerging protuberances (6) and one or several perforations (7).

(19) The central element (4) is formed by a flat plate shaped as an open profile on its upper part. This open profile preferably has a section selected from the group formed by: U-shaped, V-shaped, semi-circular, shaped with two parts that run parallel to each other and two U-shaped parts, shaped with two parts that run parallel to each other and two V-shaped parts, or shaped with two parts that run parallel to each other and a semicircular part.
