[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating condition setting system for a lubricating pump device that supplies lubricating oil to machine tools, industrial machines, and the like, and more particularly to a controller for operating the pump based on various operating conditions. The present invention relates to an operating condition setting system for a lubricating pump device, which sets operating conditions for a lubrication pump device installed therein.

2. Description of the Related Art Generally, an electric intermittent discharge type gear pump as shown in, for example, FIG. 13 is known as a lubricating pump device equipped with a controller for operating the pump based on various operating conditions. This lubrication pump device 1
Is a tank 2 for storing lubricating oil, a base 3 provided on the tank 2, and a tank 2 provided on the base 3 and driven.
The gear pump 5 that sucks the lubricating oil therein and discharges it through the discharge port 4, the electric motor 6 that is provided in the base 3 and drives the gear pump 5, and the operation of the gear pump 5 based on the operating conditions that are provided in the base 3 and are set. And a controller 7 for performing.

The controller 7 is, for example, an electric motor 6
Sends a start signal and a stop signal to the electric motor 6
Drive the gear pump 5 intermittently to drive the gear pump 5. The drive time from the sending of the start signal to the sending of the stop signal (corresponding to the lubricating oil discharge time) and the pause from the sending of the stop signal to the sending of the start signal Time and time are managed by setting a built-in timer (not shown). To set the timer, the controller 7 has an input unit 8 including a touch button for inputting a drive time and a rest time, and a liquid crystal display unit 9 for displaying an input screen for input from the input unit 8. I have it. Then, in accordance with the conditions of a lubricating system (not shown) having pipes and valves connected to the discharge port 4, the input unit 8 is operated in advance to input the drive time and the rest time, and the lubrication pump device 1 Is working.

[0004]

By the way, in the controller 7 of the conventional lubrication pump device, since the operating conditions such as the drive time and the rest time are input in the input section 8 provided in the controller 7 itself, The user can relatively freely change the setting of the operating condition while being used in a factory or the like, and in that case, if the operating condition is changed beyond the proper range, the lubricating pump device 1 itself Of the lubrication system such as piping and valves, and eventually of the machine tool or industrial machine lubricated by the lubrication pump device 1. there were. For example, if the drive time is set to exceed the permissible operating time per time of the electric motor 6, it may cause a failure of the electric motor 6. Further, for example, if the down time is set to be equal to or less than the required oil amount of the lubrication system, it causes a failure of the machine tool or the industrial machine lubricated by the lubrication pump device 1. Alternatively, if the down time is set to be short, there is a problem that the discharge becomes frequent and the lubricating oil is supplied in excess of the required oil amount, resulting in waste of the lubricating oil.

The type of controller may vary depending on the usage conditions of the lubrication pump device.
The operating conditions can be set not only by setting the above-described timer that is installed, but also by setting the pressure of the pressure switch that is installed in the lubrication pump device, or by external equipment such as machine tools and industrial machines to which the lubrication pump device is attached. There are various settings such as the setting of the count number of the built-in counter that counts the operation. Therefore, different controllers are created due to the difference in these settings. There was also a problem that the manufacturing efficiency of was also impaired. Further, since the controller 7 itself is provided with the input section 8 composed of touch buttons, that much,
There was also a problem that the device became large.

Thus, when the operating conditions of the lubrication pump device are set or changed, the setting device is connected to the controller of the lubrication pump device via wire or wireless. In this state, the operating condition of the lubrication pump device is set by the setting device. In this case, the operating conditions cannot be set by the lubrication pump device itself, so it is necessary to connect a setting device one by one.Therefore, the lubrication pump device is attached to a machine tool, an industrial machine, etc. and used in a factory or the like. It becomes difficult for the user to freely change the setting of the driving condition while the operation is being performed, so that careless setting, for example, changing the setting of the operating condition beyond the proper range will be suppressed. , May cause a failure of the lubrication pump device itself, a failure of the lubrication system such as piping and valves, and eventually a machine tool or industrial machine lubricated by the lubrication pump device. The number of situations that occur is reduced. Also, since the operating conditions are set by the setting device, even if there are differences in various settings, it will be possible to deal with one type of controller, making it different for each model as in the past. Need not be performed, which improves the manufacturing efficiency of the controller.

If necessary, the controller cannot be rewritten with transmitting / receiving means for transmitting / receiving data such as the operating conditions, and predetermined unique information relating to the lubricating pump device in which the controller is mounted.

It is configured with. Since the controller is provided with the unique information storage means that cannot be rewritten by the setting device, it is possible to prevent more inadvertent setting or change.

Further, since the controller can be configured by a microcomputer equipped with a CPU, the lubricating pump device can be downsized, and the setting device can be configured by a general-purpose personal computer, a mobile phone, etc.
Versatility can be increased.

Furthermore, if necessary, the above setting device

The display device of the setting device has a function of displaying the pattern input screen read by the pattern input screen reading device on the display unit. With this, since the patterned pattern input screen corresponding to the control code is used, the input can be easily performed, and the reliable setting corresponding to each start-stop device can be performed.
It is possible to prevent more careless settings and changes.

If necessary, the controller's unique information storage means is provided for each starting / stopping device such as a timer, counter, pressure switch, etc. for the controller to start / stop the pump of the lubricating pump device. It is configured to have a function of storing the control code related to the controller among the plurality of control codes provided as unique information, and the setting device is provided for each of the plurality of control codes to input setting items of operating conditions. Pattern input screen storage means for storing a plurality of patterned pattern input screens, a control code reading means for reading the control code of the controller from the unique information storage means at the time of connection with the controller, and a control code reading means The pattern input screen corresponding to the control code read by the means is stored in the pattern input screen Constituted by a pattern input screen reading means for reading from, and constitutes a function of causing a display section to display the read pattern input screen the pattern input screen reading means on the display means of the setting device. As a result, a single setting device can be used for various types of lubrication pump devices, but among the plurality of control codes provided corresponding to each start / stop device for starting and stopping the pump of the lubrication pump device. Since the control code related to the controller is not rewritable as unique information, it is possible to prevent unintentional rewriting, prevent further inadvertent settings and changes, and prevent undesired changes in start / stop equipment. The cause of the failure can be prevented.

Therefore, using this signal, for example, a warning is issued or the input is invalidated. Also in this respect, it is possible to prevent arbitrary rewriting, and to prevent a more careless setting or change.

Furthermore, if necessary, the controller is operated by operating data measuring means for measuring operating data for calculating the cumulative operating time of the pump, and operating for storing the operating data measured by the operating data measuring means. Data storage means is provided, and the setting device is provided with operation data reading means for reading operation data stored in the operation data storage means of the controller.

BEST MODE FOR CARRYING OUT THE INVENTION An operating condition setting system for a lubricating pump device according to an embodiment of the present invention will be described below in detail with reference to the accompanying drawings. The same components as those described above will be designated by the same reference numerals. The operating condition setting system for the lubricating pump device according to the embodiment of the present invention is shown in FIG.
As shown in FIG. 2, the operating condition is set, and a system for setting the operating condition of the lubrication pump device 1 equipped with the controller C that operates the pump 5 based on the operating condition is set in the controller C of the lubrication pump device 1. A setting device S, which is connected via a wire or wirelessly and sets operating conditions in the controller C at the time of this connection, is provided separately from the lubrication pump device 1.

As the lubricating pump device 1 whose operation is controlled by the controller C, there are various types, for example, there is an electric intermittent discharge type gear pump 5 as shown in FIG. A tank 2 for storing lubricating oil, a base 3 provided for the tank 2, a gear pump 5 driven by the base 3 for sucking the lubricating oil in the tank 2 and discharging it from a discharge port 4, and a base 3. An electric motor 6 that drives the gear pump 5 is provided.
The controller C is provided on the base 3 adjacent to the electric motor 6. A lubrication system (not shown) in which a plurality of well-known quantitative valves are attached to the discharge port 4 via piping
Are connected. Reference numeral 9 is a liquid crystal display unit for displaying various settings. A feed button 9a for manually driving the pump 5 is also provided.

The controller C sends a start signal and a stop signal to the electric motor 6 to drive the electric motor 6 to drive the gear pump 5 intermittently. From the sending of the starting signal to the sending of the stop signal. Drive time (corresponding to the lubricating oil discharge time) and the pause time from the transmission of the stop signal to the transmission of the start signal are managed. This controller C
Management of the drive time and rest time of the
It is performed based on a start-stop device (not shown) such as a pressure switch, and the lubrication pump device 1 can be appropriately selected. For example, there are the following modes.

(A) Management of driving time For example, there are the following three modes. (A1) The drive time is measured by a timer attached to the controller C, and a stop signal is sent based on the set time of the timer. (A2) The driving time is determined based on a signal from a pressure switch mounted on the lubrication pump device 1 which operates by the discharge pressure of the pump 5, and a stop signal is transmitted based on a signal from the pressure switch. The discharge pressure becomes maximum when the lubrication system valve (not shown) has finished operating.
This is detected by the pressure switch and the pump 5 is driven intermittently. In this case, in order to ensure the operation of the valve in the lubrication system, the delay time set by the timer from the signal from the pressure switch to the transmission of the stop signal is set as "pressure time-up time" (Fig. 7). Determined. Also,
In this case, there may be no signal from the pressure switch due to equipment failure or the like, so the maximum drive time of the pump 5 is defined as "pump operating time" (FIG. 7). If the “pump operating time” has come, for example, the driving of the pump 5 is stopped, and a warning signal is sent to turn on the warning lamp or sound the warning buzzer. (A3) The drive time is, for example, a periodic signal from a machine tool or an industrial machine to which a lubrication device is attached is sent to the controller C.
A stop signal is transmitted based on the number of counters set by the counters measured by the counter attached to.

(B) Rest time For example, there are the following two modes. (B1) A pause time is measured by a timer attached to the controller C, and a start signal is transmitted based on the set time of the timer. (B2) The down time is, for example, a periodic signal from the machine tool or the industrial machine to which the lubrication device is attached is sent to the controller C
A start signal is transmitted based on the set number of counters measured by the counter attached to the counter and set in the counter. In this case, the maximum waiting time is "count time up time" because the set number of counters may not be reached due to equipment failure, etc.
(FIG. 8). If the "count time up time" has come, for example, the driving of the pump 5 is stopped, and a warning signal is sent to turn on a warning lamp or sound a warning buzzer.

Therefore, the management of the drive time and the rest time of the controller C is determined as the operation mode according to the usage state of the start-stop equipment such as the timer, the counter and the pressure switch selected for each lubrication pump device 1. That is, as the operation mode, for example, when both the drive time and the rest time are managed by timers, a combination of (A1) and (B1) (hereinafter referred to as "timer-timer"), a pressure switch, When using the timer, (A
When the combination of 2) and (B1) (hereinafter referred to as "pressure-timer") is performed with a timer and a counter, (A1)
And (B2) (hereinafter referred to as "timer-counter"). In addition, there are various combinations.

The operation execution means 13 that operates the pump 5 based on the conditions is provided. Since the controller C is composed of a microcomputer equipped with a CPU, the lubricating pump device can be miniaturized. Further, since the setting of the operating conditions is performed by the setting device S, even if there are various setting differences, it becomes possible to deal with the controller C as one type, and different from model to model as in the conventional case. Therefore, the manufacturing efficiency of the controller C can be improved.

Further, in the unique information storage means 11 of the controller C, the controller C is the pump 5 of the lubrication pump device 1.

In addition, there are various combinations. The unique information includes a model code provided for each lubrication pump device 1. In the embodiment, the model code and the control code are associated with each other, and the lubrication pump manufacturer or the like stores the unique information storage means 1 in advance.
Written to 1.

Further, the pattern input screen (G1, G2, G
As for 3 ..., For example, when both the drive time and the rest time are managed by timers, the above (A
Since the operation mode (“timer-timer”) relating to the combination of 1) and (B1) is set, a “timer-timer input screen” is prepared in which the corresponding operating condition setting items can be input, as shown in FIG. To be done. On the "timer-timer input screen", the drive time of the pump 5 (timer set time) can be input as "discharge data". The pause time of the pump 5 (timer set time) can be input as "pause data".

Therefore, the operation of the operating condition setting system for the lubricating pump device 1 according to the embodiment of the present invention is as follows. A description will be given according to the flowcharts shown in FIGS. First, when the lubrication pump device 1 is shipped, as shown in FIG. 10, the controller C is set in advance at the shipping source. At this time, as shown in FIG. 3, the manufacturing date or manufacturing number is written in the "read-only area" of the unique information storage means 11 (1-
1), write model code (1-2), write control code (data corresponding to operation mode) (1-
3).

Next, when the user sets or changes the operating conditions, the operation is performed as follows. As shown in FIG. 1, when the setting device S is connected to the controller C, the ROM 20 is inserted and the device is started up, FIG.
As shown in Fig. 10, a work selection screen appears (Fig. 10 (2-
1)). As a result, as shown in FIG. 5, “Confirm and change setting data” is selected and the button is pressed) (FIG. 10 (2-
2)). As shown in FIG. 11, in the setting device S, the control code reading means 27 reads the control code of the controller C from the unique information storage means 11 (3-1). As a result, the input range regulation corresponding to the control code read by the control code reading means 27 is read from the input range regulation storing means 30, and the input violation signal sending means 32 monitors the input (3-2).

Further, the pattern input screen reading means 28 reads the pattern input screens (G1, G2, G3, ...) Corresponding to the control code read by the control code reading means 27 from the input screen storing means and the controller C
The current setting of is read (3-3). As a result, the pattern input screen (G1, G2, G) read by the pattern input screen reading unit 28 on the display unit 22 is displayed on the display unit 24.
3 ...) is displayed together with the current setting of the controller C (3-4). In this case, for example, if the control code of the controller C corresponds to the operation mode (“timer-timer”), as shown in FIG. 6, the “timer-timer input screen” in which the corresponding operating condition setting items can be input. (G
1) ”is displayed. If the control code of the controller C corresponds to the operation mode (“pressure-timer”), then FIG.
As shown in, the "pressure-timer input screen (G2)" in which the setting items of the corresponding operating conditions can be input is displayed. If the control code of the controller C corresponds to the operation mode (“timer-counter”), as shown in FIG. 8, the “timer-counter input screen (G3)” on which the corresponding operating condition setting items can be input is displayed. Is displayed.

If any of the pattern input screens (G1, G2, G3, ...) Corresponding to the controller C can be used without changing the setting of the operating conditions, the confirmation button is pushed to finish (3- 5, 3-6). If there is a change (3-7), the content of the change is input (3-8). In this case, the input violation signal transmitting means 32 monitors the input (3-9), and if there is an input from the input section 21 that violates the input range regulation, the input violation signal transmitting means 3
2, an input violation signal is transmitted, and based on the input violation signal from the input violation signal transmission means 32, a warning (error message) such as “out of setting range” is displayed on the display unit 22 and the input is invalidated. (3-10). Therefore, it is possible to prevent unintended input and rewriting, and prevent accidental settings and changes. When the confirmation button is pressed when the input is completed, the operating condition writing means 25 causes the input unit 21 to operate.
The operating conditions input from the above are written in the "readable / writable area" related to the operating condition storage means 12 of the controller C (3-11), and the processing is ended (3-12).

In such a setting, since the operating condition cannot be set by the lubricating pump device itself,
Since the setting device S must be connected one by one, the user freely changes the operating condition setting when the lubrication pump device 1 is attached to a machine tool, an industrial machine or the like and is used in a factory or the like. Is difficult to do, and therefore
Inadvertent settings, for example, changes in operating condition settings that exceed the appropriate range will be suppressed, causing failure of the lubrication pump device 1 itself, or failure of the lubrication system such as piping and valves. It is possible to reduce a situation in which the machine tool or the industrial machine lubricated by the lubrication pump device 1 is caused to malfunction.

In the controller C, the unique information storage means 1 that cannot be rewritten by the setting device S.
Since the items stored in No. 1 are provided, it is possible to prevent more inadvertent settings and changes. Furthermore, a patterned pattern input screen (G
, G2, G3, ...) are used, input can be performed easily, and reliable setting corresponding to each starting / stopping device can be performed. The situation is prevented. Particularly, the control code related to the controller C among the plurality of control codes provided corresponding to each of the starting and stopping devices for starting and stopping the pump 5 of the lubrication pump device 1 cannot be rewritten as the unique information.

Pattern input screen storage means for storing a pattern input screen, control code reading means for reading the control code of the controller from the unique information storage means at the time of connection with the controller, and pattern input corresponding to the control code read by the control code reading means The pattern input screen reading means for reading the screen from the pattern input screen storage means In this configuration, one setting device can be used for various types of lubrication pump devices, but a plurality of controls provided for each start / stop device for starting and stopping the pump of the lubrication pump device. Since the control code related to the controller in the code cannot be rewritten as the unique information, it is possible to prevent unintentional rewriting, prevent further inadvertent settings and changes, and prevent start and stop. It is possible to prevent the cause of failure due to arbitrary changes of equipment.

Further, a setting device is provided for each of a plurality of control codes, and a plurality of input range rules defining the input range of the operating condition setting items are provided. When an input violates the input range rule, an input violation signal is issued. If the input range is violated, an input violation signal will be sent.If this input is used, for example, a warning is issued or the input is invalidated. Also in this respect, it is possible to prevent rewriting without permission, and to prevent a situation in which even more careless setting or change is performed.

Furthermore, when the controller stores the operation data for calculating the cumulative operating time of the pump and the setting device reads the operation data, the setting device reads the operation data, Since the operating condition of the lubrication pump device can be grasped, the cause can be easily analyzed when there is some kind of failure. Further, when the setting device is configured to execute the test operation by the controller, the state of the lubrication pump device can be grasped by the test operation, so that the failure can be easily found and more It can contribute to the realization of a reliable setting and lubrication environment.
