Definitions

  • the invention relates to an industrial truck, in particular a forklift or reach truck, with a driver's workplace and a driver's shelter roof, which includes a penetration-resistant, transparent roof panel for the protection of the driver.
  • the trucks include counterbalanced forklifts and reach trucks, which have a driver's workplace as well as a load section located immediately in front of the driver's workplace.
  • the load part usually comprises a lifting mast with a height-adjustable load-receiving means, in particular a load fork.
  • These trucks are also used in shelf warehouses with high rack heights in particular. This creates the risk that the load or parts of the load fall down when handling, such as when settling or picking up from an upper shelf.
  • a driver's roof In order to protect the driver in the driver's workplace in such a case, it is known to provide a driver's roof.
  • This driver's shelter roof can be formed of a strut roof, which is protected by metal bars or grating above the driver's workplace of the driver.
  • a disadvantage of this prior art is a limited view of the driver on the upper working range of the truck, i. the working area of the lifting device when it is moved on the lifting mast at the upper end of the lifting area.
  • a display device for example a display
  • a display device for example a display
  • the dashboard and the drive part are formed relatively low.
  • Such displays arranged in the region of a dashboard or on the upper side of a drive part are placed in such a way that the driver has the display when the load handler is lowered and during the drive of the industrial truck in the direct field of vision.
  • an operator located in the driver's workplace during load handling and in particular when picking up or setting down a load, in particular at higher lifting heights directs the view towards the load part in the direction of the load or upwards.
  • load handling and in particular when receiving or depositing a load, in particular at higher lifting heights, with the operator facing the load upwards, there is thus the problem that the operator has a display device arranged on the dashboard or on the upper side of the drive part
  • the driver of the truck must therefore turn his head and change the line of vision to see the information on the display during load handling at high lifting heights. Through the required rotation of the head and changing the line of sight hydraulic functions of the truck can not be operated meanwhile, thereby reducing the handling capacity of the truck. It also results in an unfavorable ergonomics in the load handling at high lifting heights.
  • Such display devices are usually not transparent and therefore narrow or narrow the load-part-side field of view of the operator on the load part and the load to be handled. Therefore, these display devices are usually made compact and small. However, this means that only a small amount of information can be displayed. As a rule, only one piece of information, for example the lifting height or the weight of the load, can be displayed. In addition, the compact dimensions of these display devices lead to poor readability of the displayed information.
  • the present invention has for its object, an industrial truck of the type mentioned in such a way that a display of information for the driver when viewed through the roof glass upwards without affecting the field of view of the driver is possible.
  • the roof panel is provided with a designed as a transparent display display device for displaying information for the driver.
  • the driver it is possible for the driver to keep track of the load even at the load handling in larger lifting heights and at the same time to be informed about driver-relevant information that is displayed on the transparent display of the roof window. Due to the design of the display device as Transparent display while the driver's field of view is not limited. In contrast to the state of the art after the EP 2 518 009 B1 in which a display is arranged in the front region of a conventional driver's roof with no transparent roof glass, the invention offers the driver the opportunity to look directly up through the roof window and at the same time read the transparent display.
  • the transparent display is glued to the roof panel.
  • the display can also be laminated from above or from below onto the roof panel.
  • the transparent display is arranged between two panes in multi-layered design of the roof panel.
  • the roof panel itself is advantageously made of glass, in particular laminated glass.
  • laminated glass panes are also referred to as bulletproof glass in designs which are particularly resistant to breakage or breakdown. They consist of several layers of glass panes, between which plastic films are arranged.
  • the roof panel is made of a transparent plastic material, which is also für herein- or penetration-resistant.
  • the display is designed as a transparent electroluminescent display (LED).
  • Transparent electroluminescent displays have a structure in which a light emitting layer, usually a phosphor layer, is disposed between a front and a back electrode, the front and rear electrodes being made of a transparent and transparent material, around which Transparency and transparency of the entire display to achieve.
  • Such transparent electroluminescent displays have a high robustness, a long service life and a high resistance to environmental influences, for example oil, fats, acids and chemicals, and can be used at temperatures of -50 ° to + 85 ° C, so that such displays suitable for use in industrial trucks even under harsh environmental conditions and within cold stores.
  • transparent electroluminescent displays are water-resistant and water-resistant, so that these displays can be used inside warehouses and when the truck is operating outdoors.
  • transparent electroluminescent displays have a high image brightness, high contrast and a high viewing or reading angle of up to 180 °, so that an optimal readability of the information displayed can be achieved during operation of the truck.
  • the readability of the displayed information for the operator can be further improved by a monochrome or multicolor display of the displayed information in a transparent electroluminescent display by a suitable color choice, such as yellow, orange or red.
  • the display is designed as a transparent thin-film electroluminescent display (TFT).
  • TFT transparent thin-film electroluminescent display
  • Such a transparent thin-film electroluminescent display which has a flat and film-like structure, can be formed in any shape, curved or curved, for example, and thus also in complex shapes, whereby such a display can be easily located at an appropriate and suitable location in the Field of view of the driver mounted on the roof panel and can be easily adapted to the conditions of the truck.
  • the formation of the transparent electroluminescent display in thin-film technology further enables improved optical properties in the form of reduced light scattering, whereby the readability of the displayed information can be further improved.
  • the display is designed as a transparent organic electroluminescent display (OLED).
  • OLED organic electroluminescent display
  • Such displays have organic light-emitting diodes, ie, luminous thin-film components made of organic semiconducting materials.
  • OLED displays One advantage of OLED displays is the very high contrast, because they do not require backlighting.
  • the load weight determined by means of a weighing device can be displayed in the transparent display and in the case of an overload, these can be displayed.
  • the lifting height and / or the tilt angle of the load-receiving means can be displayed in the transparent display when operating the lifting device of the lifting device.
  • the type of load or from the set lifting height restrictive vehicle reactions such as a maximum speed or a maximum lift height.
  • the goods information of the load can be displayed in the transparent display.
  • driving the truck it makes sense to display the current vehicle speed or, with a recorded load, a maximum permissible vehicle speed.
  • restrictive vehicle reactions for example a required reduction of the driving speed
  • restrictive vehicle reactions can be displayed.
  • a warehouse navigation system in the transparent display a directional display or a required change in direction a corresponding turn signal are displayed to guide the operator to a target position in the warehouse.
  • an order can be displayed in the transparent display of a higher-level warehouse management system that performs a job control in a warehouse.
  • symbols of an Assisenzsystems can be displayed, for example, a Hub Whynassistenzsystems and / or a Neigewenkelassistenzsystems the load-carrying means that guides the driver in the load handling of a load and / or supported.
  • the display extends substantially over the entire width of the roof panel.
  • the large area of the display makes it possible to display several pieces of information simultaneously and easily readable.
  • the display is preferably arranged in the load-part-side, the highest adjustment range of the load-receiving means covering the driver's view of the roof window. In this way, the driver is at the maximum lifting height of the lifting device monitoring the display information possible without having to take his eyes off the load.
  • the invention offers a whole series of advantages:
  • the driver has all relevant information for load handling, even at high heights and thus steeply upwards through the roof window directed view in his direct field of view and thus does not have to change his line of sight. This leads to a better ergonomics. Since all information relevant to load handling lies in the direct field of view during load handling, hydraulic functions, for example, can be operated continuously. Assistance systems, in particular for load handling, which support and / or guide the driver during load handling, can provide the best possible assistance information and assist the driver in the best possible way. If the transparent display is not activated, it is completely transparent. Thus, only as much visible space is taken as is required for the display of the corresponding information. Overall, the The driver's direction of view when reading the display information during load handling at high lift heights is not changed, the driver's view is not obstructed and the handling capacity is increased. In addition, space can be saved because the display is integrated in the roof panel.
  • the truck is a reach truck.
  • the reach truck has a driver's workplace 1 for a driver 7.
  • the driver's workplace 1 is closed at the top by a driver's roof 3, which has a transparent roof panel 4.
