Abstract

The present invention concerns a transport system for transporting objects in a branched track system. The transport takes place in vehicles suspended from a hollow square beam 1 with a slit 9 in the bottom. Inside the beam there is a beam carriage 2. The vehicle 3 and the carriage 2 are joined together by a device which passes through the slit 9 in the bottom of the beam. The carriages 2 select a path through the track system without any movable switch elements being needed in the track. To ensure that the carriages 2 do not fall through the slit in the bottom of the beam at branch points or cross-over points, carrier wheels 5 run in channels 7. A guide wheel 6, which is in contact with a guide rail 4, stabilizes the carriage 2 as it passes through the branch points or cross-over points. In this way, the non-active carrier wheel can be lifted out from its channel 7. This lifting can be done automatically by the carriage 2 being inclined by contact of the guide wheel 6 with the guide rail 4 or by the carriage 2 itself being arranged to lift the non-active wheel from its channel 7. By this method, a vehicle can be driven via only half of the beam. A vehicle which is stationary in one beam half can also be moved, for example sideways, by the whole beam half being moved. <IMAGE>

Description

~ P = - RQ! CD 10 15 20 25 30 5 ms IQ Another object of the invention is to enable a division of the beam longitudinally into two halves. One half of the beam that contains a beam trolley can then be moved. The other half of the beam can be used by other beam trailers for travel. In this way, for example, a station can be arranged with parallel parking spaces. The need for space will be limited.

In order to be able to achieve this, in the present invention the roof of the beam is internally provided with guide rails, against which guide wheels on the trolley run, at the same time as the support wheels of the beam trolley run in wheel gutters. By stabilizing the beam vehicle with the help of the guide wheels against the guide rails in the beam roof and then lifting the support wheels out of the gutter at branch and weaving points, the possibility for the vehicle to choose its own way is maintained while maintaining high safety.

According to one embodiment, the support wheels can be lifted out of the gutter by tilting the entire beam trolley by a force from the guide wheels and in another embodiment by lifting the support wheels out of the gutter.

The invention is described in more detail below with reference to the accompanying drawings, in which figure 1 shows the beam, beam trolley and vehicle seen from the side, figure 2 shows a section through the beam and the beam vehicle, figure-S shows the beam seen from above with the slot in the bottom of the beam excellent and the triangular unstoped areas, figure 4 shows the beam seen from above with guide rails of varying width in the roof of the beam excellent, figure 5 shows a beam section without gutter, Jm, 10 15 20 25 30 LD lock. * Ål CLJ IX RQ (fl figure 6 shows a beam section with gutters and where the guide rail in the roof tilts the beam trolley so that the support wheel that does not carry is lifted out of its gutter, figure 7 shows a track section with gutters where the support wheel that does not carry is lifted by a mechanism in the vehicle, figure 8 shows how the beam can be divided longitudinally so that one vehicle can drive past another.

Figure 1 shows a side view of the beam 1, the beam trolley 2 and the vehicle 3 in undisturbed travel straight ahead.

Figure 2 shows how two support wheels 6 support the guide rail 4 in the roof of the beam while the support wheels 5 run in wheel gutters 7 in the lower edge of the beam.

Figure 3 shows how the weak triangular areas 8 arise at branching and weaving points by locating the slot 9 at the bottom of the beam 1.

Figure 4 shows how the guide rail 4 inside the roof of the beam 1 can be varied in width to force the beam trolley to tilt.

Figure 5 shows how the support wheel 6 through the pressure against the guide rail 4 prevents tipping.

Figure 6 shows how the guide rail 4 through the wheel 6 forces the beam carriage 2 to assume an inclined position.

Figure 7 shows how a wheel 5 actively lifts out of its chute while the support wheel 6 takes support against the guide rail 4.

Figure 8 shows how the beam could be separated into two halves where one vehicle can pass another.

Claims (5)

UI 10 15 20 25 _. >. F.) Uwl ~ Ö Patent Claims Vehicle-based gear unit for suspension rails, a transport system consisting of beams (1), beam trolleys (2) and vehicles (3), where the beam trolleys (2) are provided with support wheels (5) running in chutes (7) and with guide wheels (6) which abuts against guide rails (4) in the beam roof, characterized in that the individual vehicles themselves can choose their own branch points and where the beam carriages are such that when only one side support wheel carries, the other side support wheel can be lifted out of its wheel chute then the steering wheel (6 ) has taken over the stabilization of the beam vault (2) by contact with the guide rail (4) in the roof of the beam. Transport system according to claim 1, characterized in that the guide rail (4) is positioned in such a way that the beam carriage (2) is forced by the guide wheel (6) to travel through the beam (1) so that the non-supporting support wheel is lifted out of its chute. Transport system according to claim 1, characterized in that the beam trolley (2) is arranged by itself to actively lift the support wheel of the non-supporting side out of its wheel chute (7) - Transport system according to claims one and two or one and three, characterized in that the beam 1 can be separated longitudinally after the beam trolley 2 has been stabilized in one of the two possible positions. Transport system according to claims 1 to 4, characterized in that the wheel chute 7 has only a marked vertical wall facing the slot.
