The invention relates to transporting rollers (22) for transporting essentially flat articles, to holding-down means (23) for pressing the articles onto transporting rollers (22), and to a transporting system (30). In this case, the transporting roller (22) is of at least two-part configuration and comprises a spindle element and at least one track element (1), the latter enclosing the spindle element in a tubular manner. The invention consists in designing transporting rollers (22) such that the spindle element is flexurally rigid, and in presenting an essentially cylindrical holding-down means (23) which is of at least two-part configuration and comprises a spindle (8) and at least one sleeve (13), wherein the internal diameter of the sleeve is larger than the external diameter of the spindle, the spindle (8) and the sleeve (13) of the holding-down means are coupled, and a pin-like carry-along element which is oriented away from the spindle (8) and engages in a cutout (16) on at least one side of the sleeve (13) is fitted on the spindle (8). The invention allows articles to be processed continuously, while keeping to the correct track as precisely as possible, with careful handling, in the case of which, under a wide range of different conditions in respect of temperature, pressure and surrounding medium, the workpieces are exposed to only a low level of mechanical loading.
A transporting roller for transporting essentially flat articles, the transporting roller having at least one track element, wherein
The transporting roller as claimed in any of the preceding claims, wherein the spindle element is encapsulated in a fluid-tight manner in relation to the medium through which the articles are to be transported.
The transporting roller as claimed in any of the preceding claims, wherein track elements (1) can be joined together to form any desired length.
The transporting roller as claimed in any of the preceding claims, wherein a track keeper (6) is conical.
The transporting roller as claimed in any of the preceding claims, wherein it is possible for a track keeper (6) to be made up of at least two disk elements which can be positioned symmetrically in relation to one another and can be fitted on a track element (1).
The transporting roller as claimed in any of the preceding claims, wherein the track element (1) has at least two spaced-apart bearing elements (3) which are fixed on the rotary spindle of the track element (1), the diameter (4) defined by the bearing elements (3) being smaller than the diameter (7) of the track keeper (6) and larger than the diameter of the track element (1) in the region outside the bearing elements (3) and the track keeper (6).
The transporting roller as claimed in any of the preceding claims, wherein the track element (1) is produced from plastic.
The transporting roller as claimed in any of the preceding claims, wherein the track element (1) can be driven.
The transporting roller as claimed in any of the preceding claims, wherein the width of the track element (1) corresponds at least to the width of the articles (24) which are to be transported.
The transporting roller as claimed in any of the preceding claims, wherein a fixing ring is located on the bearing spindle, the internal diameter of a track element (1), at least at one location, being smaller than the diameter of the fixing ring.
The transporting roller as claimed in any of the preceding claims, wherein the track element (1) is retained on the bearing spindle by a fixing ring made of metal.
The transporting roller as claimed in any of the preceding claims, wherein a track element (1) has at least one compensation fold (21) in order to accommodate changes in length of the track element.
The transporting roller as claimed in any of the preceding claims, wherein track keepers (6) of track elements (1) of adjacent transporting rollers rotate, without contact, one in front of the other, one beside the other or one inside the other.
A holding-down means for exerting pressure on essentially flat articles, wherein
A transporting system for transporting essentially flat articles, having transporting rollers for transporting flat articles, the transporting rollers having at least one track element,
A transporting system for transporting flat articles, having transporting rollers and having a holding-down means, wherein the track element (1) has at least one track holder (6), which has a diameter (7) which is larger than the diameter of the track element (1) in the region outside the track keeper (6), the transporting roller is of at least two-part configuration and comprises a bearing spindle and at least one track element (1), the latter enclosing the bearing spindle in a tubular manner, the bearing spindle is flexurally rigid, and the essentially cylindrical holding-down means is of at least two-part configuration and comprises a spindle and at least one sleeve, the internal diameter of the sleeve being larger than the external diameter of the spindle.
