Track system with lift connection

The invention relates to a running rail system, in particular for in-house overhead conveyance in the clothing industry, with several tracks of rails, each arranged in floors accessible by a lift, each with a free end have in front of the lift door, with at least one running rail section in the lift that ends approximately perpendicular to the lift door, and with at least one bridging rail piece, which with the lift door open into a rail section in the lift with the free one The bridging position connecting the end of the respective floor rail track for continuous conveying can be brought.

There is a running rail system of this type known in which the free end of the fixed rail line perpendicular to the lift door

ends and the track section in the lift is fixed in such a way that that it is aligned with the free end when the elevator door is open. The bridging rail piece is a loose rail section with a cross-section and length corresponding to the running rail system, which slightly exceeds the distance between the free end of the stationary rail line und.dem lift section. This piece of rail If necessary, the rail ends to be connected by the handrail placed and removed again after the conveyed goods have been transferred. It can be carried in the elevator or on every floor next to it are ready or standing by the lift door. This arrangement has a number of significant disadvantages. It is troublesome to move the rail piece each time to keep and remove again after use. Manipulating the rail section can endanger people and / or the lift or the conveyed goods are damaged. Whether stored in or outside the lift, the rail section is a disruptive element, if it is stored upright there is a risk that it will fall over and cause damage. Since the bridging rail piece is simply placed on the rail ends to be connected, there is also the risk that it is accidentally knocked down again, be it when the conveyed goods are carelessly transferred, or as a result, that the elevator door is closed without the bridging rail piece being removed. In all of these cases it can be significant This could result in damage to the conveyed goods or to people.

The object of the invention is to provide a running rail system of the initially mentioned described type with simple means so that in a simple and safe way the conveyed from the stationary Floor rails in the elevator, or vice versa, can be promoted.

The object is achieved according to the invention in that the bridging rail piece at one of the rail ends to be connected

around a vertical axis from the bridging position to one approximately vertical rest position can be pivoted and at least in the bridging position is mounted tiltable around a horizontal axis for height compensation in a small range of motion.

The bridging rail piece pivoted at one end of the rail can be brought back into the bridging position with an effortless pivoting movement. That doesn't require physical strength, either a certain size of the operator. Tampering is safe because the bridging rail piece does not fall down can. This also has the advantage that even unfavorable height differences in the lift position can be bridged safely. Essential is also the fact that the pivotably mounted bridging rail piece does not cause any damage even if it is inadvertently in the bridging position before the lift door is closed was left. The lift door can close the bridging rail piece when closing forcibly swivel into the rest position.

The bridging rail piece advantageously has a stop for the rest position so that its pivoting path is limited and the is adaptable to local conditions. As an additional safeguard, it can be fixed in the rest position.

In a preferred embodiment, a bridging rail piece is arranged on each of the stationary floor rail strings. In this way, compared to an alternative solution of arranging a single bridging rail section on the running rail section in the lift, there is an increased need for bridging rail sections corresponding to the number of floors. The non-significant in the simple structure of the arrangement costs are outweighed by the advantage that more space is available on the floor for the ÜberVrückungs- to Vorfügung than the lift. It can be used in

its length, but also its shape, can also be adapted to different conditions in the individual floors. In one or more floors, it may be necessary to have the running rail system not in alignment with the rail section in the lift, but in the
parallel to the lift door,
rail piece for that

To let the angle to end, in extreme cases Floor have a curvature. In addition to the format, a special, The rest position of the bridging rail section adapted to the spatial conditions to get voted.

In an advantageous further development of the invention Running rail system, the running rail section can be mounted in the lift so as to be displaceable in relation to its longitudinal direction. This is going through the pivotally mounted bridging rail piece, which even in the event of an unintentional displacement from the running rail section slide, but not fall, allows. A particularly economical transport of conveyed goods in the lift results from this, that in the lift several, transversely displaceable and lockable stored Running rail sections can be arranged. Each running rail section can thus be attached to the stationary bridging rail piece brought in, loaded with conveyed goods and. to another place in the ι Lift -to be transported.

In a preferred embodiment, there are two rails in the lift at a "distance from each other and parallel to the lift door and fixed the transversely displaceable running rail section (s) is / are mounted transversely displaceably on these rail pieces. This arrangement is in particularly easy to manufacture if the rail pieces, which are fixed in place in the lift and arranged parallel to its door, correspond to the profile of the the rest of the track system and the cross-sliding track sections in the lift with the same sliding or

rolling elements are mounted on it, with which the conveyed goods on the ' Track system is promoted. This means that no special components are required for the lift equipment.

Each track section in the lift can be at its facing the lift door End of an attachable and removable safety device have against the rolling of conveyed goods. The capacity of the running rails in the lift can thus be fully utilized without that conveyed goods can fall off due to transverse displacement in the lift and / or jerky lift movements. The safety device can consist in an advantageously simple manner of a plastic cap which can be pushed onto the free end of the rail. This has the added bonus Advantage that when manipulating in the limited interior space of the lift there is no risk of injury from sharp rail ends.

For a track system in which the track is about a Has triangular or angular cross-section with a symmetrically upwardly directed tip and the conveyed goods on the running rail Support brackets that encompass both sides from below and are supported on the upper side of the track by means of two rollers inclined towards one another hangs, can be centered symmetrically on the top of the running rail and in the longitudinal direction a vertical pivot axis for the bridging rail piece bearing part can be at least partially pivoted about a horizontal axis. The bearing part will while being carried by the running rail itself, without it hindering the rollers and thus the promotion. Since such a bearing part * on the top of a running rail without further ado can be attached, an already existing conveyor system of the known type described above, i.e. with a loose bridging rail piece, can be subsequently changed according to the invention.

3ci of a preferred embodiment has two bearing part mutually parallel plates, between which the vertical

Mounted pivot axis and the horizontal axis is arranged. the Storage of the axles is made possible despite the small overall width of the bearing part. The plates can advantageously be removed at their rail ends Area each have a bevel that allows this area to be lowered onto the upper edge of the slide and limited. If the entire bearing part including the vertical pivot axis on the top edge of the rail by means of the horizontal Axis mounted, the lower edges of the bearing part limit the pivoting movement about this axis in both directions, namely the the lower edge areas between the horizontal axis and the free end of the rail cause the downward movement -tilted edge area.e on the other side of the pivot axis the upward movement. A downward movement of the bridging rail piece is also made possible and limited by the fact that the ends of the bridging rail section facing each other in the bridging position and the end of the rail, on which the bridging rail piece is mounted, each have a bevel, those in the same sense of direction to each other, but under different, with aligned rail edges resulting in a gap Slopes run.

Another embodiment of a bearing part has a portion which is fixedly arranged on the running rail and a portion thereon around a horizontal axis pivotable, the vertical pivot axis supporting Section on.

An angled, in rest position, can be attached to the bridging rail piece with one leg in a press fit on the bridging rail piece be arranged supporting rail end holder approach.

This is particularly advantageous for manual conveying, where the conveyed material is set in motion with a push without affecting the running distance can be calculated exactly. In addition, kanri on the angled Approach the stop for .the rest position be arranged, for example a pin supported against the bearing part.

At the free end, the bridging rail piece advantageously has a nose that can be placed on the opposite rail section with a roof-like cross-section. The inclined surfaces * of the ITase have the advantage that when forces act from the side the free end of the bridging rail piece forcibly raised slightly and thus above the rail section on which it rests, is moved away. This is of particular advantage if the sideways movement occurs unintentionally, for example from the back closing elevator door is forced. Despite the support of the bridging end, there is no risk of pinching.

The running rail system also includes running rail sections 4 arranged in a lift 3, of which, however, only one is shown in FIG. 1 for the sake of clarity. The running rail section 4 extends in the lift approximately perpendicular to the lift door, not shown, which is designed to be displaceable parallel to the door opening. On the running rail section 4, two Tragkon structures 5 are arranged at a distance from each other, each of which can be displaced on a piece of rail 6 arranged in a stationary manner in the lift parallel to the lift door. Assign ¹ to this end support bracket 7, which in each case engage around the rail portion of the bottom and on the top thereof - are supported with skewed rollers 8 - it has JEnter roof-like cross section. By means of this support structure, the running rail section 4 is displaceable in the lift transversely to its longitudinal direction. Furthermore, it can be locked in various positions by means of a locking pin 9 and locking bores 10 in the rail sections 6.

In the other end, the bridging rail piece 11 has a bevel 14 which extends from the upper edge of the rail profile downwards outwards, so that the lower edges are longer than the upper edges. On the upper side of the bridging rail piece Λ "\ is an angled approach ^ fixed. It has shape U to substantially, one of the IT leg 15a extending vertically from the top of the bridging rail piece at which it fixed _(is, extends upwardly, the transverse web 15b, which is longer than the first U-leg, extends horizontally and perpendicular to the longitudinal direction of the bridging rail piece, and · the second U-leg 15c »which is considerably shorter than the first leg 15a, one parallel to the bridging rail piece 11 extending horizontal angulation Λ ^ ά aufweist- the angled portion 15'd is directed towards the hinged end of the bridging rail piece 11 toward. at the crossbar 15b is further arranged at unequal intervals to its two ends, a stop pin 16 such that it extends horizontally and in the same Directional sense as the bend 15d extends, but it is shorter than this.

On the free end of the stationary rail track 1, a bearing part designated as a whole as 17 is attached. It has two plates 18 which are fastened at a small distance opposite one another, symmetrically to the upper edge of the stationary rail track in its end area. A horizontal axis 19 is mounted between them. Two further plates 20 are mounted pivotably about this horizontal axis 19 in the same way as the plates 18, but with a spacing that enables them to protrude between these plates. In addition, they are supported over a part of their length under the action of gravity on the upper side of the rail track Λ . The vertical axis of rotation 12, which carries the bridging rail section 11, is mounted between its areas protruding beyond the free end of the rail line 1.

Pig. 3 shows another embodiment of the bearing part 17 'in FIG enlarged. Scale. It has only two plates 20 ', whose The arrangement corresponds essentially to that of the plates 20. They are rotatably mounted about a horizontal axis 19 ', which in turn is fixed aii is attached to the end of the rail track 1, and are supported with part of its lower edge on the end of this rail track. In the area of the projecting part, as in the case of the plates 20 the vertical axis of rotation 12 fixed between them. The area going beyond the horizontal axis 19 'on the other side the plates 20 'has a ^ bevel 21, which runs so as if a corner had been cut off the rectangular plate.

The function of the described track system is as follows:

The rest position of the arrangement in the lift area is shown in FIG. The bridging rail section 11 is pivoted ün the vertical axis of rotation 12 so that it is approximately perpendicular to the end of the fixed rail line 1. This position is too limited to prevent further turning on the rail track by the stop pin 16, which rests with its free end on the side of the plate 20 in this position. The bend 15d of the angled approach rests in a light press fit on the top of the rail track and secures the bridging rail section 11 against involuntary rotation in the other direction. At the same time, it prevents support elements or support brackets for goods being conveyed arriving on the rail track 1 from rolling out over the free end. These support elements or support brackets have to be imagined in accordance with the support structures 5 and the support brackets 7 with rollers 8. If conveyed goods are to be transferred from the rail line 1 into the lift J, after the lift door has been opened, the bridging rail section 11 is pivoted into the over-printing position, as shown in FIG. 1.

if a plastic cap 22, which is fastened there by means of a small chain, has to be removed beforehand from the end ^{v of the running rail section 4- facing the lift door in the lift.} In the bridging position, the bridging rail piece 11 is aligned with the end region of the running rail 1 and the running rail section 4 in the lift and forms a continuous conveying path. A deviation in the lift height is compensated for by pivoting the plates 20 about the axis 19. In this position, conveyed goods can be conveyed past the bearing part 17 via the bridging rail piece 11 onto the running rail section 4 or vice versa. After the end of the conveyance, the bridging rail piece is pivoted in the opposite direction. The end of the running rail section is secured with the plastic cap. The running rail section 4 can, if necessary, be displaced transversely to its longitudinal direction on the running rail pieces 6 and fixed by means of the snap-in pin 9. Another running rail section present in the lift can now be brought into alignment with the rail track 1 and loaded or unloaded.

The bridging rail strand swiveled into the rest position after the conveying process releases the lift opening to close the door. If the pivoting is forgotten and the door closes caused in the direction of arrow A in Fig. 2, it automatically pushes the bridging rail piece out of the way. The roof-like The nose is raised by its inclined support surface to such an extent that it can be moved away over the running rail section.

ways to open the track system result when a path is crossed on which tall objects have to be transported from time to time. Furthermore, it is possible within the scope of the invention by a curved bridging rail piece free ends of rail tracks or to connect support rail sections to a continuous conveyor line that are not aligned with each other. E.g. can with a bridging rail piece running at right angles in the plane, a running rail section ending perpendicular to the lift door be coupled in the lift with an end of the track that ends parallel to the lift door. This is appropriate e.g. where the lift does not have a sliding door, but a pivoting door. Another possible variation is that an inclined ' tidy jumper rail piece, straight or curved, around a vertical axis pivotable at different heights connecting rail areas with each other.

In the event that only a single track section is used in a lift should be provided and the running rails end in the same way in front of the lift on all floors, that can bridging rail piece can also be pivoted on the running rail section in the lift. It is then only a piece of bridging rail and the corresponding camp organs are necessary.

The invention extends not only to rails with angled Cross-section and with support brackets of the type shown. In the context of other rail systems, other bearing parts for the bridging rail piece and / or the arrangement and suspension of track sections in the lift can be selected.
