Definitions
- the invention relates to a method for Hubtownnvorians in a truck, according to the preamble of claim 1.
- Industrial trucks which are guided on a mast having a lifting device, such as a fork, to handle goods, are used in particular in the form of counterbalanced forklifts or reach trucks in racking. It becomes more complicated for the serving people or drivers with increasing height of the shelves and requires more time to accurately approach the correct lifting height to receive a stored pallet or sell a product in a shelf.
- Hub wastednvor anglessysteme which help a driver as an assistance system to approach storage bins in a high-bay warehouse
- the lifting heights of the shelves of the shelf storage are stored in a control computer.
- the driver can then select a specific storage space via a control panel of an operating and display device, which is to be approached by the system supported.
- the Hubheimnvor Horsystem then moves the desired lifting height then automatically on, or in other embodiments, the lifting movement, which is entered by the driver via an operating lever, stopped at the selected lifting height.
- 160 storage heights can result, which are programmed and sorted into 8 storage areas, each with 20 lifting heights corresponding to the shelves.
- a driver In a storage operation, therefore, a driver must select the desired shelf, for example via the control panel of the control and display device by entering the storage area and then subsequently a single shelf.
- a disadvantage of this prior art is that while the driver performs the information in the operating and input device, he can not operate the working hydraulics of the linear actuator via the operating lever. This results in delays and the handling capacity of the truck is reduced. Also, the name of the shelf for the driver, for example, must be identified by a signage on the shelf. However, this requires that the driver often have to read a compartment number up to the shelf at a greater distance, and then turn to the control and input device on a dashboard by leaning forward to enter the compartment number at a short distance into it , After a subsequent check of the displayed inputs, the driver must then lean back in his seat and the usually arranged in the range of an armrest or right on the seat control lever for the working hydraulics of the lifting drive. Overall, this workflow is not particularly ergonomic.
- the programming of the stored lifting heights in the control computer is often carried out as a service or by a fleet manager. This has the disadvantage that the subject numbers, for example, do not have to be arranged monotonically rising. The higher shelf number does not have to correspond to the higher storage position.
- the present invention has for its object to provide a method for Hubtownnvor inches an industrial truck available, which avoids the disadvantages mentioned above and can be done intuitively and efficiently Hubtownnvor inches by a driver.
- the selection by the switching element takes place in that a previous operation of the switching element is terminated and the function of the switching element for the selection and / or the display of the next reached, stored lifting height is coupled to the simultaneous operation of the operating element for the lifting movement.
- an operator or a driver of a truck makes a manual compartment selection. All compartments of a rack are displayed with their stored lifting heights in an order sorted according to the lifting heights.
- the method can be activated, for example, by an input in a display and control device on a dashboard, are also activated by the switching element, but also be activated in principle.
- the operator raises or lowers the load handling device via the operating element for controlling the lifting height, for example a joystick with the one working hydraulics is operated with lifting cylinders of a mast, the control device displays in the display device to the next accessible shelf of the shelf.
- a switching element arranged directly on the operating element for the lifting movement, this can be selected and the lifting movement automatically stops at the selected lifting height.
- this avoids the non-ergonomic operating order with an upward view for reading a shelf number, entering that shelf with a view downwards, and subsequently reading the values, and finally looking up again for checking.
- the switching element which is initially operated, for example, held in a switching position, and in which the selection is made by the release of the switching element For example, releasing a switch.
- the coupling makes it possible to use a switching element for a plurality of functions, which only serves for the selection of a lifting height upon actuation of the operating element for a lifting movement for lifting or lowering.
- the switching element is a push-button switch, which is previously pressed and released for selection.
- control device starts the display of the next reached, stored lifting height in the display device with the actuation of the switching element.
- the truck has sensor means for detecting a load resting on the load-receiving device and displays the control device at a detected load stored lifting heights for storage and otherwise stored lifting heights for outsourcing.
- control device of the total number of stored lifting heights then only in each case those for a storage operation or alternatively for a removal process in a lifting movement.
- the sensor means may be a light barrier for detecting a pallet on the load handling device.
- the sensor means may be a load sensor for detecting a weight resting on the load receiving device.
- control device displays as the next reached lifting heights only those for a storage operation and in the case of entering a selection command in a display and operating device next reached lifting heights for a removal process.
- no load detection such as, for example, by detecting a pressure in a lifting hydraulics as working hydraulics, it can be provided as a default that those of the programmed lifting heights are displayed for a storage operation.
- About a manual input in one Operating device can then switch an operator or a driver on an indication of lift heights for Auslagervortician.
- the load-receiving device has a tilting device and the control device adjusts the inclination of the load-bearing device automatically.
- the automatic adjustment of the inclination of the load receiving device can take place simultaneously during the execution of the previously described method for starting or selecting a lifting height.
- both the start of the correct lifting height and the setting of the inclination of the load receiving means, in particular a horizontal position of the lifting device or vertical position of the lifting mast can be significantly facilitated.
- the goods handling capacity increases, the truck can be operated more ergonomically, and the movement process becomes easier and more efficient for the driver.
- the additional automatic adaptation of the inclination of the load receiving device can be activated together with the previously described method. This can be done by a setting in a control and display device in general or the adjustment of the inclination can be activated by additional tilting elements.
- control device until reaching the selected lifting height, the load receiving device horizontally.
- the correction of the tilt angle of the load receiving device takes place shortly before the selected lifting height is achieved simultaneously with the lifting movement.
- a return inclination of the load receiving device can be maintained for the greater part of the lifting movement and the load can be secured on the load receiving device. Due to the horizontal position, the Load picking device to be introduced both in a stored pallet, as well as a settling of a load with a pallet in a shelf space.
- control device during lifting or lowering movements to compensate for bending of the mast, the load receiving device in the same absolute inclination, in particular the horizontal, hold.
- a measuring or detecting device for the inclination of the load receiving device is present as an absolute value relative to the vertical or the ground, this can be compensated by the described method and the control device can keep the load on the device at a selected inclination, especially in the horizontal.
- the control device can keep the load on the device at a selected inclination, especially in the horizontal.
- there may be a rapid change in the inclination of the load receiving device when a load is placed in a shelf in a high position and vice versa, when a load is absorbed and, for example, the load is lifted from its storage space in the height range of Lagerfachritihubs.
- a correction or adjustment of the required inclination of the load receiving device can be carried out automatically at the same time as the lifting movement or the automated handling of the picking up or setting down of a load.
- the working process becomes more efficient because no parallel operation of a tilting operation device for manually adjusting the inclination of the load handling device and a lift height preselection is required.
- control device the adaptation of the inclination of the load receiving device, as long as an actuation of a working hydraulics, in particular a lifting movement.
- the automatic implementation of the adjustment of the inclination of the load receiving device is thus coupled to the operation of a working hydraulics, in particular the lifting movement.
- the process steps for adapting the inclination of the load receiving device can simultaneously be performed by the controller be carried out as soon as such an adjustment of the inclination is required or makes sense. For example, shortly before reaching the selected lifting height or, when the selection of the next stroke height takes place, the adjustment of the inclination by the control device.
- the control device can perform the adjustment of the inclination upon actuation of a tilting switching element, which can be reached by the same hand as for the operation of the operating element for the lifting movement.
- the automatic adjustment of the inclination can be activated.
- the tilting element can be arranged so that it can be operated in parallel with respect to operating elements of the working hydraulics.
- the tilting element may correspond to the switching element.
- the activation of the adjustment of the inclination is effected by the same switching element as for the selection of the next to be approached lifting height.
- This can be set, for example, in a display and the control unit. In such a case, a correction of the inclination always takes place with the selection of the next lift height to be approached.
- the tilting element can also be constructed so that the activation is triggered by releasing a push-button as a tilting element.
- control device terminates the adjustment of the inclination of the load receiving device when a tilting operation device is actuated.
- the above-described method for automatically adjusting the inclination may be active until, for example, a load handling operation is completely completed. It can be active as long as a working hydraulics is actuated, in particular a lifting movement takes place, or it can be activated when a tilting switching element is actuated in the sense of a switch. In all these cases, it makes sense and beneficial to stop the automatic adjustment of the tilt when a manual intervention takes place in the operated tilting device for manual control of the inclination of the load receiving device is actuated.
- the Fig. 1 schematically shows a method according to the invention for Hubtownnvorines an industrial truck.
- a control device 1 receives from a lifting height memory 2 the individual subjects of a shelf associated lifting heights. For example, sensor means for detecting a load applied to the load receiving device, the control device 1 also receives a load handling information 3, whether a storage operation or a paging operation must be made, depending on whether a load rests on the load receiving means.
- the control device 1 carries out automatic sorting 4 of the lifting heights according to their height-wise sequence and generates a display 5 of the next reached lifting height on a display device 6.
- a driver 7 selects during a lifting movement by actuation of the switching element a desired lifting height, just as next reached lifting height is displayed continuously during the lifting movement on the display device 6 and can be selected by the driver via a switching element.
- the Fig. 2 shows an industrial truck 8 in the form of a reach truck 9 in front of a shelf 10, in which the inventive method is used.
- the shelf 10 has a plurality of shelves 11, wherein in the example shown in a top shelf 12, a load 13 is stored.
- the reach truck 9 has a lifting mast 14, on which a load receiving device 15 in the form of a Fork 16 is guided vertically movable.
- the driver When the truck 8 moves up to the rack 10, for example, in a region of the shelf, which is indicated by the capital letter "A”, from a compartment labeled "A7" at 8 m height, corresponding to the top shelf 12, a load To outsource, the driver starts the lifting movement of the fork 16. During the lifting movement, the driver activates the Hub Ounvor inches by pressing a pushbutton, not shown.
- the control device thereupon each represents the next higher shelf 11 and the corresponding lifting height or it is displayed as a process outsourcing because no load on the fork 16 is detected by the sensor means.
- the shelf "A7" is displayed with the stored height of 8m for the removal in the display in the present example.
- the load fork 16 is still aligned in the horizontal position during the lifting movement by the control device 1, so that the load 13 can be accommodated with the fork 16. Also occurring after receiving the load 13 bending the mast 14 can be automatically compensated by the control device 1, for example, before the truck 8 moves backwards to move the load 13 from the shelf 12 out.
