Description

DISPLAY DEVICE OF THE INDUSTRIAL VEHICLE

An embodiment of the present invention relates to a display device for an industrial vehicle, and more specifically, to a display device for an industrial vehicle that sets a height at which a fork is to be moved and displays the same.

It usually includes a fork and carries and loads the load through it. Recently, in order to reduce the operating cost of warehouses, these industrial vehicles are increasingly used for multi-level stacking at high locations to stack a lot of loads in a narrow space.

To ensure accurate multi-stage loading of these loads, auxiliary devices such as cameras are used to control the fork height of the industrial vehicle.

Auxiliary devices must be installed separately in industrial vehicles, and there is a problem that separate maintenance and design for their installation are required to prevent damage to the auxiliary devices and to ensure freedom in their installation space.

Alternatively, there are industrial vehicles that include a feature where the operator stores the height of the forks and the industrial vehicle stops at this stored height.

However, in these cases, there is a problem that the set height is changed through a complicated process, such as the operator changing the mode for changing the menu screen and its settings. In addition, in these cases, there is a problem that the expandability for the operation of industrial vehicles is limited because only limited memory is used to set the height, such as the location of the warehouse and the shape of the hallway (rack).

An embodiment of the present invention provides a display device for an industrial vehicle that enables a worker to easily set the height of a fork for multi-stage loading and store various multi-stage information.

According to an embodiment of the present invention, a display device of an industrial vehicle includes a keypad for a worker to set height information of a fork of the industrial vehicle and information on a corridor along which the industrial vehicle moves, and a display unit for displaying operation information of the industrial vehicle and information set by the keypad.

In addition, the display device of the industrial vehicle described above may further include a control unit that determines whether the worker will set at least one of the fork height information or the corridor information based on information input from the keypad and outputs the result to the display unit.

Additionally, the keypad may be a numeric pad that is operated by the operator and includes multiple numbers.

In addition, the control unit can change and store the hallway information to a number entered from the number pad after receiving a hallway information setting mode from the keypad.

In addition, if the control unit does not receive a hallway information setting mode from the keypad, it can store the height information of the fork in the number input from the number pad.

In addition, when the control unit receives a number N from the number pad, it can compare the difference in height of the current fork at number N and the height of the fork stored in a number smaller than number N, and display on the display unit whether or not the height information of the current fork can be stored at number N.

In addition, when the control unit receives a number N from the number pad, it can compare the height difference between the height of the fork stored in a number greater than N and the height of the current fork at N, and display on the display unit whether or not the height information of the current fork can be stored at N.

Additionally, the control unit can delete the height information of the fork when a preset number is input from the number pad.

In addition, when a number is input from the number pad, the control unit can compare the current fork height with the maximum fork height among the fork heights stored in the number input from the number pad to display the target height to which the fork is to be moved.

In addition, the control unit can determine that the hallway information setting mode is in place when a preset number from the number pad is input.

In addition, a display device of an industrial vehicle installed on an industrial vehicle including a fork according to one embodiment of the present invention includes a display unit including a number pad for an operator to set height information of a fork of the industrial vehicle and information on a corridor along which the industrial vehicle moves, a corridor information display area for displaying information on a corridor along which the industrial vehicle moves, and a fork information display area for displaying a target height and current height of the fork set by the number pad.

Additionally, the above corridor information display area can display selected corridor information and a number corresponding to a preset fork height in the selected corridor.

Additionally, the fork information display area can display the current fork height and the target height to which the current fork is to be moved.

Additionally, when displaying the target height, the number where the target height is stored can also be displayed.

According to an embodiment of the present invention, a display device of an industrial vehicle enables a worker to easily access, change and save the height of a fork for multi-level loading when changing the setting.

In addition, the display device of the industrial vehicle according to one embodiment of the present invention allows a worker to set and easily edit a plurality of different fork heights for each corridor by using a number pad.

Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those skilled in the art can easily implement the present invention. The present invention may be implemented in various different forms and is not limited to the embodiments described herein.

It is noted that the drawings are schematic and not drawn to scale. The relative dimensions and proportions of parts in the drawings are exaggerated or reduced in size for clarity and convenience in the drawings, and any dimensions are for illustration only and not limiting. In addition, the same reference numerals are used to indicate similar features where the same structural elements or parts appear in more than one drawing.

The embodiments of the present invention specifically illustrate ideal embodiments of the present invention. As a result, various modifications of the diagrams are expected. Accordingly, the embodiments are not limited to the specific form of the illustrated area, and also include modifications of the form by manufacturing, for example.

Hereinafter, with reference to FIGS. 1 to 7, a display device (101) of an industrial vehicle according to one embodiment of the present invention will be described.

The display device (101) of an industrial vehicle according to one embodiment of the present invention includes a keypad (200) and a display unit (100), as shown in FIG. 1 and FIG. 4.

The display device (101) of the industrial vehicle is installed in the industrial vehicle and outputs information such as the operation information of the industrial vehicle or its driving status to inform the driver, and can receive information from the driver and transmit it to the vehicle control unit (300).

The display device (101) of an industrial vehicle according to one embodiment of the present invention includes a keypad (200) and a display unit (100), as shown in FIG. 1 and FIG. 4.

The keypad (200) is operated by a worker, and the worker can set the height information of the fork of the industrial vehicle and the corridor information along which the industrial vehicle moves.

The display unit (100), as illustrated in Fig. 4, displays the operating information of the industrial vehicle and the information set by the keypad (200). Specifically, the display unit (100) can display information such as the driving status or working status of the industrial vehicle so that the worker can visually recognize it. The display unit (100) can display information such as speed or warnings to the worker.

In addition, the display unit (100) can display set information input from a worker through the keypad (200). That is, the display unit (100) can output information manipulated by a worker through the keypad (200).

Specifically, the corridor information may be information given to a rack (corridor) through which an industrial vehicle moves, as illustrated in Fig. 2. It may be information corresponding to corridors A, B, C…

With this configuration, the worker can set the height information of the fork and the corridor information through the display device (101) of the industrial vehicle and recognize the output information thereof. Accordingly, the display device (101) of the industrial vehicle according to one embodiment of the present invention makes it easy to set the height of the fork according to the corridor and effectively allows the worker to recognize the information thereof.

In addition, according to one embodiment of the present invention, the display device (101) of the industrial vehicle may further include a control unit (300).

The control unit (300) can determine whether the worker will set one or more of the fork height information or the hallway information based on the information input from the keypad (200) and output it to the display unit (100).

Specifically, the control unit (300) can determine whether the worker changes the setting of the current fork height information or the setting of the corridor information based on the information input from the keypad (200). In addition, through this determination, the control unit (300) can output information about the worker's setting change to the display unit (100). Accordingly, the worker can recognize the setting status currently being changed through the keypad (200) through the display unit (100).

Additionally, the keypad (200) according to one embodiment of the present invention may be a number pad including a plurality of numbers.

The keypad (200) is formed as a number pad, so that the operator can set and reset the fork height information or corridor information by selecting one of a plurality of numbers.

That is, the hallway information is input as a preset number through the number pad, and the control unit (300) can output the hallway information matching the preset number as text (A, B, C…) on the display unit (100).

Specifically, the operator can set or edit the height to which the fork will be moved via input from the number pad.

Accordingly, the operator can set and reset the fork height information or corridor information and select or deselect it by selecting the number pad of the keypad (200) of the display device (101) of the industrial vehicle without having to operate multiple keys such as complex mode conversion.

In addition, the display unit (100) according to one embodiment of the present invention may include a hallway information display area (400) and a fork information display area (500).

The corridor information display area (400) can display corridor information. Specifically, the corridor information can be a letter or icon that allows a worker to determine the selected corridor information (410), or a corridor number (or letter: identifier) (410) having different fork heights corresponding to the selected corridor.

Specifically, a corridor (rack) number corresponding to the number pad is preset and can be output on the display unit (100) according to the worker's selection.

That is, in one corridor (410), multiple numbers (420) can store different fork height settings.

The fork information display area (500) can display the current fork height (550) and the stored fork height information (530). Specifically, the target height (520) can include the fork height (520) to which the current fork is to move upward among a plurality of corridor numbers (510) and the number information (510) at which it is stored.

In addition, the control unit (300) according to one embodiment of the present invention can change and store the hallway information to a number entered from the number pad after receiving the hallway information setting mode from the keypad (200).

When the worker presses a preset number among multiple numbers on the number pad, the control unit (300) can determine that the worker is currently setting the hallway information.

For example, the control unit (300) can determine that when the number 9 on the number pad is pressed, the mode for setting the hallway information has been changed. That is, the worker can set the hallway information by pressing the number 9 on the number pad. That is, the control unit (300) can determine that when the number 9 on the number pad is pressed, the worker can change the hallway information.

And the control unit (300) can receive a signal when the operator inputs another number on the number pad and store the height information of the fork in the number selected by the operator.

At this time, when the operator presses 9 and then presses another number N on the number pad for a preset period of time, the control unit (300) receives the signal and sets or changes the height information of the fork to N, thereby storing the height information of the fork to N.

In addition, the control unit (300) according to one embodiment of the present invention can display on the display unit (100) whether or not the height information of the current fork can be stored in number N when N is input from the number pad.

When the operator inputs N through the number pad, the control unit (300) can determine whether the current height of the fork can be stored in N and output the status thereof on the display unit (100).

If the control unit (300) determines that the height of the fork can be stored at number N, it can display text (11) indicating that the height of the fork has been stored at number N, as shown in Fig. 4. Then, the control unit (300) can cause this text message (11) to disappear from the display unit (100) after a certain period of time (approximately 3 seconds).

Specifically, when the operator inputs number N through the number pad, the control unit (300) can compare the difference between the height of the current fork and the height of the fork stored in a number smaller than number N to determine whether or not the height information of the current fork can be stored in number N.

In addition, when the operator inputs number N through the number pad, the control unit (300) can compare the difference in height of the current fork and the height of the fork stored in a number greater than number N to determine whether or not the height information of the current fork can be stored in number N.

For example, when the operator inputs 3 on the number pad, the control unit (300) can determine whether the current height of the fork can be stored in number 3. The control unit (300) compares the difference in height of the current fork and the height of the fork stored in a number smaller than 3 (the closest number between 2 and 1).

At this time, the control unit (300) determines whether the current height of the fork is greater than a number smaller than 3 and whether the difference exceeds the set reference height (α) by considering the precision of the control characteristics of the fork, etc. For example, the set reference height may be 500 mm.

In addition, the control unit (300) determines whether the height of the fork stored in a number greater than 3 (the closest number among 4, 5, etc.) is greater than the height of the current fork and whether the difference between them exceeds the set reference height.

That is, when the control unit (300) wants to set the height of the current fork to number 3 within the selected corridor number, it can determine whether the height of the current fork is located at a fork height set between a number smaller than number 3 and a number larger than number 3 and output to the display unit (100) whether or not the height information of the current fork can be stored at number 3.

If the control unit (300) determines that the current fork height cannot be stored at number 3, as shown in Fig. 4, the text (12) indicating that the current fork height setting is impossible can be displayed on the display unit (100).

Additionally, the control unit (300) can omit the comparison process for numbers smaller than N when N is 1.

Additionally, the control unit (300) can omit the comparison process for numbers greater than N when N is 8.

That is, the height of the fork stored at number N can be the target height.

In addition, the control unit (300) according to one embodiment of the present invention can delete the height information of the fork when a preset number is input.

When the control unit (300) receives a preset information deletion number from the number pad, it can delete all height information of the fork stored in the current corridor.

Specifically, when the control unit (300) receives a signal of 0 from the number pad during setting of the height of the fork within the selected corridor information, it can delete all the heights of the forks within the selected corridor information.

For example, you can delete all the set heights of the forks stored in 1, 4, 7, and 8 in corridor C.

At this time, the control unit (300) does not delete the set height of the fork stored in the unselected corridor. In addition, the control unit (300) can display a message (13) indicating that all of the pre-stored fork heights in the selected corridor are deleted on the display unit (100), as shown in Fig. 4.

In addition, the control unit (300) according to one embodiment of the present invention can output the height information of the fork set to the number corresponding to the input number pad to the display unit (100).

The control unit (300) compares the current fork height with the fork height stored in the number entered from the number pad when a number is entered from the number pad before moving the fork to a certain height position in the set corridor (rack). Specifically, when a plurality of different fork heights are stored through a plurality of numbers in one corridor, the control unit (300) compares the current fork height with the maximum fork height among the plurality of fork heights.

In addition, when the corridor information is selected by the worker through the number pad, the control unit (300) displays a number corresponding to the height of the fork preset in the corridor information on the display unit (100).

That is, the control unit (300) displays information about the corridor (rack) and numbers corresponding to the heights of multiple forks corresponding to the selected corridor on the display unit (100). In other words, the operator can select or deselect the number corresponding to the heights of multiple forks corresponding to the currently selected corridor using the number pad, and the number in which the fork height is stored.

The control unit (300) can set the target height to which the fork will be moved to the closest upper height among the current fork height (550) and the heights of the forks set to multiple numbers, and display the target height (520) on the display unit (100).

In addition, the control unit (300) according to one embodiment of the present invention can exclude the height information of the corresponding fork when setting the target height of the fork if the same number is entered through the number pad.

The control unit (300) can exclude the height of the fork stored in the selected corridor information from the target height determination when a number identical to one of the multiple numbers stored in the selected corridor information is re-entered.

Hereinafter, with reference to FIGS. 1 to 5 and FIG. 7, the control process of the display device (101) of the industrial vehicle of the present invention will be described.

The control unit (300) determines that the worker is setting or resetting the hallway information when the number pad number 9 is entered (S100).

The control unit (300) causes letters or icons corresponding to the corridor in the corridor information display area (400) of the display unit (100) to flash (S110).

The control unit (300) outputs a preset character to match the number of the number pad pressed by the worker with the character corresponding to the flashing hallway on the display unit (100) (S120). That is, the worker can confirm through the display unit (100) that the hallway character matching the number pad he or she is currently pressing is output. At this time, if 9 is pressed again and the number is pressed, the selection of the hallway of the selected number can be canceled. Specifically, the control unit (300) has presets such as 1 for hallway A, 2 for hallway B, and 3 for hallway C. That is, the number pad (200) pressed by the worker can be output as a hallway number (410) in the hallway information display area (400).

When the worker selects a corridor with the current number, the control unit (300) stops the blinking of the corridor letter or icon corresponding to the currently selected number on the display unit (100) (S130). For example, as shown in Fig. 4, when the worker presses 3, corridor C can be selected and its blinking can be stopped. That is, the worker can change the corridor number at this stage.

The control unit (300) displays the height information of different forks stored in the currently selected corridor in multiple numbers in the corridor information display area (400) of the display unit (100) (S140). That is, the control unit (300) indicates that the heights of different forks are stored in the currently selected C corridor in multiple numbers.

In other words, as illustrated in FIG. 4, the control unit (300) displays the corridor information (410) and the numbers 1, 4, 7, and 8 (420) corresponding to the preset fork heights stored therein in the corridor information display area (400). That is, in this case, as illustrated in FIG. 4, the worker can know that different fork heights are stored in corridor C at numbers 1, 4, 7, and 8, respectively.

After the corridor selection is completed, the operator moves the fork (10) by operating the operating unit placed in the cabin (S210). Specifically, the operating signal of the operating unit is transmitted to the driving unit (20) through the control unit (30) of the industrial vehicle, and accordingly, the height of the fork (10) is changed. The height of the fork (10) can be transmitted from the control unit (30) of the industrial vehicle to the control unit (300) of the display device (101) of the industrial vehicle.

The control unit (300) receives the number pad information selected by the operator to store the current fork position (S220). That is, the operator can change or set the fork height set to a desired number among the selected corridors.

At this time, the control unit (300) can determine whether to change the fork height setting of the selected number when the number of the number pad (200) selected by the worker is maintained for a certain period of time (approximately 3 seconds).

The control unit (300) determines whether the current fork height can be set to the number of the number pad selected by the worker (S230). Specifically, the control unit (300) compares the position of the fork stored in the number pad selected by the work vehicle, the largest number closest thereto, and the smallest number closest thereto.

For example, if the corridor information display area (400) displays C (410), 1, 4, 7, 8 (420) and the worker selects 4, the control unit (300) compares the fork height stored in 1, the fork height stored in 7, and the current fork height.

That is, the control unit (300) determines whether the current fork height is greater than the fork height stored in No. 1 and less than the fork height stored in No. 7. In addition, it can also be determined whether each of these differences is greater than 500 mm.

At this time, if the control unit (300) satisfies the conditions described above and can store the current fork height in the number selected by the operator, as shown in Fig. 4, it displays on the display unit (100) that the height setting of the fork in the selected number is complete (S240).

Then, the control unit (300) stores the current fork height in the selected number (S250).

Alternatively, if the control unit (300) does not satisfy the conditions described above and thus it is impossible to store the current fork height in the number selected by the operator, as shown in Fig. 4, the control unit (300) displays on the display unit (100) that the height setting of the fork in the selected number is impossible (S260).

By repeating the above-described number selection, multiple fork heights can be set in the hallway at different heights.

In addition, after setting the corridor number (S100), if the control unit (300) receives a 0 signal from the number pad for 3 seconds or more as shown in FIG. 5, it deletes all fork heights corresponding to multiple numbers stored in the currently selected corridor (S310).

That is, the control unit (300) can delete all fork height numbers stored in the selected C corridor described above.

In addition, the control unit (300) displays a message on the display unit (100) that all fork heights set for multiple numbers corresponding to the selected corridor number are deleted (S320).

Hereinafter, with reference to FIGS. 1 to 2 and FIGS. 6 and 7, selection of a target height of a fork and its release will be described. That is, a worker can adjust the target height of a fork by selecting or releasing multiple numbers stored in a selected corridor.

The control unit (300) receives information from the number pad (200) entered by the worker (S410). That is, the control unit (300) receives a number selected by the worker from the number pad (200).

The control unit (300) determines whether the number selected by the worker has already been selected (S420). That is, the control unit (300) determines whether the number selected by the worker is among the selected corridor (410) and the number (420) corresponding to the preset fork height in the corridor information display area (400) of the current display unit (100).

If the number selected by the worker has already been selected and is selected repeatedly, the control unit (300) deselects the selected number (S430). Specifically, if 1, 4, 7, and 8 are displayed in corridor C on the display unit (100), the control unit (300) displays 1, 7, and 8 if 4 is selected again.

In this case, the control unit (300) can determine that the use of information stored in a previous number is excluded due to the operator's selection of a duplicate number.

Alternatively, the control unit (300) determines whether the fork height is preset for the currently selected number if the number selected by the worker has not already been selected (S440). That is, the control unit (300) can determine whether the fork height is preset for the number selected by the worker.

If the fork height is not set for the number selected by the worker, the control unit (300) can display a text on the display unit (100) to set the fork height for the selected number (S450). At this time, the control unit (300) can make this text disappear after 3 seconds.

Alternatively, if the fork height is set to the number selected by the worker, the control unit (300) outputs to the display unit (100) that the selected number is displayed (S460). That is, the control unit (300) can output the number added by the worker to the display unit (100). Specifically, the control unit (300) can output the number (420) added by the worker to the display unit (100).

In addition, the control unit (300) compares the current fork height with the maximum fork height preset in the currently selected corridor (S470). Specifically, the control unit (300) compares the current fork height with the maximum fork height among the heights of the forks stored in 1, 4, 7, and 8 of the selected C corridor.

If the control unit (300) determines that the current height of the fork is smaller than the height of the fork stored in the selected corridor, it determines whether the fork can move and outputs the target height (520) to which the fork will move from the current height of the fork to the display unit (100) (S490).

For example, the control unit (300) can output the target height to which the current fork is to be moved on the display unit (100) while 1, 4, 7, and 8 are output on the display unit (100) in corridor C.

As shown in Fig. 7, if the height of the fork is 4000 mm stored in No. 4 and the height of the fork is 7000 mm (420) stored in No. 7 (410), the control unit (300) can output No. 7 (510) and the target height (520) together in the fork information display area (500) while stating that the current fork height (550) is 5000 mm. That is, the control unit (300) can output the closest upward height from the current fork height (550) as the target height on the display unit (100).

Alternatively, if the control unit (300) determines that the current height of the fork is not smaller than the height of the fork stored in the selected corridor, the control unit (300) cannot display the moving height of the fork using the pre-stored number, and thus displays “0:0000” in the fork information display area (500) (S480). That is, in this case, the control unit (300) outputs to the display unit (100) that the stored fork height setting cannot be utilized. In other words, in this case, the control unit (300) can display 0000 for the target height and 0 for the target height number in the fork information display area (500).

At this time, the control unit (300) displays the current fork height (550) on the display unit (100).

Or, as described above, if the number selected by the worker has already been selected and is selected repeatedly and the duplicate selection number is deselected, the control unit (300) compares the current fork height with the maximum fork height while excluding the deselected number (S470). Specifically, if 4 is selected again from 1,4,7,8 in corridor C and 1,7,8 is selected and displayed in corridor C, the control unit (300) compares the current fork height with the maximum fork height among the fork heights stored in 1,7,8.

At this time, if the current fork height is 5000 mm, the fork height stored in No. 1 is 1000 mm, and the fork height stored in No. 7 is 7000 mm, the control unit (300) can display in the fork information display area (500) that the fork is moved to the target height (520) of 7000 mm.

By this configuration, the display device (101) of the industrial vehicle according to one embodiment of the present invention allows the worker to easily set and change the fork height through the keypad (200), and accordingly, the changed information can be recognized through the display unit (100).

In addition, the display device (101) of the industrial vehicle according to one embodiment of the present invention allows the operator to select and edit a corridor and a set fork height according to the corridor through a number pad, so that the fork target height can be set through the number pad without a complicated procedure through mode conversion and setting input conversion of the operating unit.

Accordingly, the industrial vehicle can change the setting of the fork height through the display device (101) of the industrial vehicle described above, so that the operator can adjust the operating unit to operate the fork to the set target height.

Although the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features thereof.

Therefore, it should be understood that the embodiments described above are illustrative and not restrictive in all respects, and the scope of the present invention is indicated by the claims described below in the above detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be interpreted as being included in the scope of the present invention.
