Automated guided vehicle for rolls of newsprint

Abstract

An object of the invention is to provide an automated guided vehicle, which can be adapted to various types of rolls of newsprint such as narrow, medium and wide, irrespective of their diameters and in which low bedding, weight lightening and energy saving are obtained. The invention solves the above-mentioned problems by providing an automated guided vehicle comprising a traveling carriage, which supports a newsprint roll and automatically transports the supported roll between a storage station and a setting area in a rotary press machine. A hoisting / lowering unit is mounted on the travelingcarriage, which hoists and lowers the supported roll of newsprint in a vertiacal direction and installs and callbacks the newsprint roll. The invention is characterized in that the hoisting / lowering unit includes two spaced-apart hoisting / lowering frames provided in parallel to a traveling road surface, hoisting / lowering means, which hoisting / lowering raises and lowers the hoisting / lowering frames, an arc-shaped connecting member, which keeps a spacing between the two hoisting / lowering frames to avoid interference with the winding paper holding arms, linear guides respectively formed on uppersurfaces of said two hoisting / lowering frames and a moving table, bridging over said linear guide, slides along the guides.

Description

technical field [0001] The present invention relates to an unmanned newspaper roll transport vehicle for unmanned transport of newspaper rolls between a storage place and a place where a rotary printing machine is installed. An unmanned delivery vehicle for newspaper rolls with a lifting unit for installation and recovery. Background technique [0002] Conventionally, in a newspaper office or the like, an unmanned newspaper roll transport vehicle is generally used to supply new roll paper to a rotary printing machine or to collect a half-way newspaper roll. And, for newspaper rolls, newspaper rolls called A rolls with a length of 1626 mm, newspaper rolls called C rolls with a length of 1219 mm, and rolls called D rolls with a length of 813mm newspaper roll paper. [0003] Figure 7 It is a schematic side view showing a state in which an unused D roll of newspaper roll R2 is mounted on a rotary printing press in a conventionally used unmanned newspaper roll paper delivery v...

Problems solved by technology

Furthermore, when the height from the walking path F to the paper feeding device of the rotary printing machine is low, the height of the volume increasing platform 250 becomes an obstacle, and the unmanned conveyance vehicle 200 cannot enter under the paper feeding device of the rotary printing machine.

[0010] In addition, for the conventional unmanned transport vehicle 200, after the lifting unit 240 descends, the opening of the traveling mechanism 220 is blocked by the lifting platform 241, so it is difficult to confirm the inside of the traveling mechanism 220, for example, it is difficult to check the rolling Maintenance of wheels and lifting unit 240 etc.

In addition, the lifting platform 241 is very heavy, so the unmanned transport vehicle 200 itself will become heavier, and the energy consumption during walking and lifting is very large, and the energy efficiency is very low.
