Definitions

• the invention relates to a transport trolley in a conveyor system for metal coils with a frame that can be moved along a conveyor line with the aid of a drive, comprising on a base frame means for lifting and lowering a support saddle along a linear vertical guide.
• a known embodiment has, for example, a central guide for the support saddle and two hydraulic cylinders for actuating the lifting mechanism.
• the guide of the lifting mechanism can be designed both as a round guide and as a rectangular guide and generally moves in a guide slot provided in the foundation. This may have to be very deep and, in order to avoid accidents, requires secure covering, possibly with cover elements carried by the coil transport trolley.
• Another known embodiment uses a so-called scissor lift table to guide the support saddle and actuate the lifting movement.
• the lifting cylinders required for lifting act on the scissor system.
• These coil carriages are relatively flat, and the opening required in the foundation is correspondingly smaller.
• the unfavorable application of force by the hydraulic cylinders to the scissor system and the non-linear stroke movement must be regarded as disadvantageous.
• Document EP 0 569 719 A1 describes a coil transport system with hovercraft for straight-ahead and cornering, in which the hovercraft has lateral guides on its long sides for lateral movement, which can be actuated alternately on the right or left side and to which guide rails are assigned.
• Document EP 0 061 557 A2 describes a conveyor system for sheet metal coils, which has a coil carriage that can be moved along the conveyor line by means of a drive.
• the coil carriage drive consists of a toothed rack that is laid along the conveyor line and meshes with a driven gear of the coil carriage, which serves as an incremental scale for a length measuring device that uses the scanning unit for the incremental scale and at least one counter for comprises the scanning pulses of the scanning unit.
• the invention is based on the object of proposing an improved construction of the transport carriage of a conveyor system for sheet metal coils with a frame which can be moved along the conveyor line and of the type mentioned in the preamble of claim 1, which on the one hand has the advantages of the abovementioned. Systems combined, but on the other hand avoids the disadvantages mentioned and is also inexpensive to manufacture.
• the object is achieved with the invention in that as a plate-shaped base frame z.
• a steel slab is used, on the purpose of linear vertical guidance, a scissor hoist is arranged, two for lifting and lowering the support saddle as a drive directly on this in mutual Distance attacking lifting cylinders are arranged.
• welded profile steel frames can also be used as the base frame.
• the device does not require a slot guide in the foundation and also ensures unrestricted access to the payload.
• the upper part of the scissor hoist is expediently designed as a supporting saddle for the payload.
• the movable part of the scissor hoist is advantageous for. B. performed on commercially available linear guides. This gives you an inexpensive and solid rolling mill-compatible guidance of the support saddle.
• the whole system consists of only four main parts, namely the hoist, the vertical guide, the chassis and the hydraulic device.
• the lifting movement is linear and independent of the current position of the scissor hoist.
• the scissor system therefore only has to take over the task of synchronizing and guiding the support saddle and does not require any lifting forces for guiding.
• pre-purchased systems can be used as the running gear, with minor adjustments if necessary.
• a version with a special housing and built-in standard parts is also possible.

• Die Conveyor system also consists of a storage station 17, a floor roller station 18, the travel path 19 and the weighing station 20, as shown in FIG. 4 and FIG. 4a.
• a steel slab is used as the base frame 3 in the coil transport trolley, on which a scissor lifting mechanism 6 is arranged for the purpose of linear vertical guidance 5, with lifting cylinder 7 arranged as a drive 2 for lifting and lowering the support saddle 4, which acts directly on it at a mutual distance.
• the upper part of the scissor hoist 6 is designed as a support saddle 4 for the payload, for example for the metal collar.
• the movable part of the scissor hoist 6 is guided on commercially available linear guides by means of sliding blocks 8. This results in an inexpensive and solid, rolling mill-compatible guidance of the support saddle 4.
• the entire system consists of only four main parts.
• the lifting movement is thus linear and independent of the current position of the support saddle 4.
• the scissor system 6 only has to take over the task of synchronizing and guiding the support saddle 4 and does not require any transmission of lifting forces.
• the coil transport trolley is equipped with a mobile hydraulic station 9 and this is connected to a cable drag chain 10 for energy supply.
• a chassis 11 equipped with drive means is arranged on the underside of the base frame 3.
• the advantage here is that a commercially available system can be used as the chassis.

• the coil transport wagon has a mobile hydraulic station 9 which is fixedly arranged on it and which is conductively connected to the cable drag chain 10 for the purpose of feeding in energy.
• the length of the lifting cylinders determines the overall height of the overall system.
• the arrangement and design of the lifting system shown in principle in FIG. 5 is provided with a double cylinder arrangement 12. Together with the guidance of the support saddle 4 on a scissor hoist 6, this results in comparatively low overall heights.
• the path required for the stroke must be fully available in the cylinder.
• the lifting height therefore determines the total height of the coil transport wagon, provided the overall length of the cylinder exceeds the overall height of the wagon.
• the double hydraulic cylinder 12 or the telescopic cylinder 14 individual strokes of two or more cylinders are interleaved in such a way that an overall stroke according to the schematic diagram in FIG. 5 results with uncomplicated means. If the upward stroke of the support saddle is to take place, a row of cylinders 12 extends first. Then, in the upper arrangement 13, the second row 14 continues until the total stroke.
