Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a shipping device, and in particular, when a failure occurs in at least one of a plurality of quantitative shipping control devices installed separately for each shipping stage at a shipping site. The present invention relates to a shipping device configured to centrally manage failure settings.

2. Description of the Related Art In a conventional shipping device, a quantitative shipping control device for controlling shipping of oil liquid is provided at each stage of the shipping site. This fixed-rate shipping control device prevents various interlock conditions such as the grounding device, location switch, etc., and failure of the flow meter when starting the shipment of oil liquid.

It is configured to confirm the reset of abnormal settings such as point failure n records due to damage to the loading arm, etc., and when all ink clock conditions are satisfied, the shipping start button is pressed to open the metering valve and carry out metered shipment. Each stage is equipped with a grounding device for each lane on one side, and six rope arms for shipping to the rolling stock. When shipping, the grounding device is attached to the trolley, the desired amount of liquid is supplied to the loading arm, and after the liquid supply is completed, the loading arm and the grounding device are removed and the product leaves the shipping site. However, for example, after shipping is completed, a rolling stock vehicle may forget to remove the grounding device and start the vehicle, and in this case, the grounding device will malfunction.If the grounding device malfunctions in this way,
Due to the earth interlock, liquid supply will not be able to be shipped to the next lorry. In such a case, as an emergency measure, an earth bypass switch is provided on the panel of each fixed quantity shipping control device. In addition, each range shipping υl
On the panel of the l1l device, in addition to the earth bypass switch, there are a number of interlock bypass switches such as a location bypass switch, an abnormality reset switch (a switch for resetting abnormal settings such as point failure registration), etc. Therefore, in conventional shipping equipment, when the grounding device breaks down as described above, a worker at the shipping site manually switches the earthing bypass switch from the normal position to the bypass position, and from then on, the earthing connection will be interrupted. During this time, the grounding device was repaired. At the time of shipping, an auxiliary grounding device was attached to the trolley, and the shipping work was carried out in the presence of workers.

Problems to be Solved by the Invention However, in the above-mentioned conventional shipping device, as mentioned above, a large number of interlock bypass switches, continuous set switches, etc. are provided on the board of the shipping control device. Therefore, there was a problem in that the operator had to go to the shipping site every time a failure occurred, which was troublesome.

In addition, in conventional equipment, each bypass switch and error reset switch must be constructed to be flameproof and explosion-proof, and each bypass switch and error reset switch that resets error settings are installed outdoors, making them susceptible to corrosion and dust. etc., which makes it difficult to turn the switch, and furthermore, each switch needs to be a key switch to prevent a third party other than the person in charge from operating it without permission. In addition, the switch becomes larger, which requires an extra installation space, and there is a problem in that the fixed quantity shipping control device becomes larger accordingly.

Therefore, an object of the present invention is to provide a shipping device that solves the above-mentioned problems.

Means and Effects for Solving the Problems The present invention provides the above-mentioned shipping device, which includes a plurality of fixed-female shipping devices installed separately for each shipping stage at the shipping site;
a main control device that manages a plurality of quantitative shipping control devices; The device is provided with a failure setting means for setting a failure when a failure occurs in at least one of the plurality of fixed quantity shipping control devices, and the failure setting means sends a failure setting signal to the relevant one via the communication line. By sending the data to the window m shipping control device and executing the next process while ignoring the failure location, the large number of bypass switches installed in the quantitative shipping device can be eliminated and each quantitative shipping 1III control device can be centrally managed. This is how it was done.

Figure 1 shows a shipping device according to the present invention. In FIG. 1, a plurality of quantitative shipping stages A to C for shipping oil liquid are distributed and arranged at the shipping site.

A main and sub-machine m device 1 is installed in an office (2) located far from the shipping site engineer. This main controller 1 is connected in series through a single communication line 2 to fixed quantity shipping control apparatuses 3A to 3G respectively disposed in each fixed quantity shipping stage A to C.
The main control device 1 centrally manages each fixed meter shipping control device 3A to 3C. The main controller 1 also has a display section 4 on the front thereof,
Fault settings.

and a keyboard 5 for performing operations for canceling the cancellation and resetting abnormal settings.

In addition, the main controller 1 is connected to pumps 6A to 6G installed in the pump yard ■ by a signal line 6', and a pump activation request signal is transmitted from the quantitative shipping controllers 3A to 3C via the communication line 2. and signal line 6' to pumps 6A to 6C.
Outputs the pump start signal via.

As shown in FIG. 2, the main controller 1 includes a CP Ll-7,
A keyboard interface 8 to which the keyboard 5 is connected, a display part interface 9 to which the display part 4 is connected, a communication interface 10 to which the communication line 2 is connected, and a pump control 110 unit 1 to which the pumps 6A to 6C are connected.
1 and a memory 12. Each part of the main control device 1 is connected by a CPU bus 13. Note that the keyboard 5 has functional keys 5a as shown in FIG.
- 5e, and a numeric keypad 5f which is operated when specifying the lane of the shipping device that has the failure setting data or when specifying each point of quantitative shipping stages A to C.

As shown in FIG. 4, the quantitative shipping control device f3A is
4, a memory 15, a memory RAM 16, a communication interface 17 connected to the communication line 2, a low-speed shipping data input section 18 into which a location signal, a ground signal, a remote switch signal, etc. are input, a valve opening/closing signal, and a lamp. a low-speed shipping data output unit 19 that outputs signals, etc.;
Display device f'! that displays the loading status of each point. 20 (2
0a to 20f).

Note that the memory RAM 16 is backed up by a battery 21, and failure setting data is transmitted from the main controller 1.
When transmitted via the communication line 2, a status indicating the bypass state is created in the memory.

Note that the display device 20 also displays that the earth interlock condition is OK based on the earth connection signal when the earth connection is made.

Further, the display device 20 similarly displays other interlock conditions. Therefore, for example, if the display device 20 does not display an image even though it is connected to the ground, it can be determined that the grounding device 36 is malfunctioning. Further, the display device 20 displays remote switch settings and the like during interlock bypass.

It should be noted that on the panel of the fixed quantity shipping control system @3A, there are no many bypass switches, abnormality reset switches, etc. that are used to set failures as in conventional systems. For this reason,
There are no switches of any kind with a flameproof and explosion-proof structure, and the bypass switch and abnormality reset switch are damaged due to corrosion.
There is no risk that the reliability of the a3A will deteriorate, and the E3A is miniaturized.

Next, the quantitative shipping device A will be explained with reference to FIGS. 4 to 6. Incidentally, since each fixed quantity shipping stage A to C has the same configuration, only fixed quantity shipping stage 8 will be explained, and explanation of the other fixed quantity shipping stages B and C will be omitted.

In FIG. 5, the quantitative shipping stage A is for shipping a predetermined amount of oil when the roller wheel 25 arrives at a predetermined position on the stage 24. 26 is a liquid storage tank in which oil liquid is stored. The oil in the liquid storage tank 26 is fed through the piping 27 by the operation of the pump 6A. Further, the piping 27 is provided with a strainer 28 , a flow meter 29 , a constant flow valve 30 , and a metering valve 31 . 32 is a loading arm, which communicates with the pipe 27, and its tip end connects to the roller wheel 25.
It is inserted into the insertion hole and discharges oil liquid. 33 is a control box of the fixed quantity shipping control device 3A, which has operation switches for setting the type of oil to be shipped and the shipping date. Reference numeral 34 denotes a grounding device which, when attached to the roller wheel 25, outputs its signal. Further, the signal from the grounding device 34 is supplied to the quantitative shipping control device f3A via the grounding receiving section 35.

Therefore, when the grounding device 234 is connected to the vehicle body of the lorry 1!25, it grounds the zero-lift vehicle 25 and ensures safety when shipping the oil. For this reason, the earthing device 3
4 is out of order, the earth interlock will not be OK and it will not be possible to ship the oil even if the start button is pressed.

36 is a location control switch, loading arm 3
Detect position 2. 37 is a remote switch, which is operated when shipping starts.

When the remote switch 37 is operated to start, the earth interlock conditions, location switch interlock conditions, reset of abnormal settings, etc. are confirmed, and a pump start request signal is output, as will be described later. Then, a valve opening signal is supplied to the seventh cutter 31a of the metering valve 31.

In addition, as shown in FIG. 6, each stage 24 of fixed quantity shipping stages A to C includes points 388 to 38 for shipping oil liquid.
f is provided. These 6 points of bond 38・a~38
Loading arms 32a to 32f and display devices 20a to 2Of are disposed, respectively.

Point 38 out of 6 points 38a to 38f
Points b and 38G are dedicated points for lane “01” on the right side of the stage, and points 38e and 38f are for lane “01” on the left side of the stage.
02” is a dedicated point.

Furthermore, points 38a and 38d are location points that allow loading arms 32a and 32b to rotate to either side of lanes "01" and "02". The moving position is detected.

Note that the location switches 36a and -36b are ON-
With an OFF switch, for example, when it is ON, the car 1i1rOI
On the J side, it is detected that when it is OFF, it is on the lane "02" side.

Therefore, the constant m shipping control device 3A controls the loading arm 3 at the location point 388.38d by turning on or off the location switches 36a and 36b.
2a and 32d are in the lane set by the control device 1.

Further, a grounding device 34 is provided for each lane of the stage 24. Therefore, for example, if the grounding device 34 in lane "01" breaks down, it is not possible to ship on that lane [011 side] due to the ground interlock conditions.

Next, the shipping operation of the shipping device having the above configuration will be explained.

First, as shown in FIG.
When you arrive at the point, turn the loading arm 32 to 0.
- It is inserted into the insertion opening of the hatch of the trolley wheel 25, and the grounding device 34 is connected to the body of the trolley wheel 25. Next, after setting the type of oil to be shipped and the amount to be shipped using the control box 33, the remote switch 37 is operated to start.

CPU1 of fixed quantity shipping control device f3A with start operation
4, IU recognizes earth interlock conditions, location switch interlock conditions, abnormal setting reset, etc. When all interlock conditions and abnormality resets are satisfied, each interlock condition etc. is displayed on the display @ 20 and the quantitative shipping control device! 3A transmits a pump activation request signal via the communication line 2. Constant M shipping control system 2?
Control device 1 supplied with the pump start request signal from 3A
outputs a pump start signal to the pump 6A that feeds oil to the quantitative shipping device A in the pump yard (2).

In this way, the pump 6A is activated and the metering valve 31 is opened. The oil in the liquid storage tank 26 is connected to the pipe 27.
and is implanted into the hatch of the roller wheel 25 from the loading arm 32. The fixed quantity shipping control device 3A integrates the flow rate measurement signal of the flow meter 29, and when a predetermined amount of oil liquid has been shipped, the fixed quantity shipping control device 3A opens the fixed quantity valve 31 to complete the shipping.

However, if the grounding device 34 or the first case switch 36's is malfunctioning or set abnormally, the interlock condition will not be met, and the start input will be ignored and the shipment will be carried out in the lane of stage 24. becomes impossible. However, when it is necessary to respond to a customer's reservation, etc., the main controller 1 may be set to have a failure, and the interlock condition at the failure location may be temporarily bypassed and the product shipped.

Here, the failure setting operation will be explained assuming that the grounding device 34 in lane 01 has failed, for example.

If the grounding device 34 is out of order when shipping to the rolling stock 25, the metering valve will not open due to the grounding interlock even if the shipping start operation is performed. In addition, the display device 2
Since the earth interlock condition OK is not displayed at 0,
It turns out that the grounding devices 3 and 4 are out of order.

Then, at Office 1, we received a notification that the grounding device was out of order.
Fault settings are made on the main υItll device 1. 1, that is, the CPU 7 of the main control device 1 executes the processing shown in FIG.

In FIG. 7, first, a key operation is performed on the keyboard 5 to set a failure. For example, rFUNJ, rob on the keyboard 5 in step S1.

When each key is pressed in the order of rOJ and rsETJ, the display screen shown in FIG. 8 is displayed on the display unit 4 (step 82
>. Then, commands corresponding to the rFUN and 0°0.5ETJ key operations are output to the communication line 2. In addition, if the location switch fails, rFUN, 0
, 1.5ETJ, a command corresponding to this key operation is output to the communication line 2.

Next, in order to indicate the fault location 818, in step S3, the number of the faulty lane "011" is entered at the position of the cursor 4a on the display section 4 by pressing the numeric keypad 5f. A command as a failure setting signal is sent to the communication port 1m2 (step 84).The command includes the address of each constant ω shipping control device 3A to 3A, a lane number, and a signal indicating the failure part. , the quantitative shipping control device 3A corresponding to the address of the command takes in this command via the communication interface 17.Then, in the control device 3A, the memory RAM1
6 stores the status indicating that a failure has occurred as set in the operation.

Therefore, as will be described later, the control device 3A performs a bypass setting of the interlock condition for the lane "01" side where the grounding device 36 has failed.

In this way, the fault setting of the grounding device 34 and the fault setting of the location switch 36 are made in the υ control device 3A! 5 settings, etc. are performed, and the same procedure is performed when resetting failure settings and resetting abnormal settings due to failure of the flowmeter, loading arm, etc.

Next, the CPU of the quantitative shipping control wave ff3A that has been set to fail
The processing executed by 14 will be explained with reference to FIGS. 9 to 11.

When the remote switch 37 is operated to start, the CPU
14 executes the processing shown in FIG. In FIG. 9, when a start signal is output from the remote switch 37 (step 511), it is first confirmed that the grounding device 34 is connected to the ground (step 512). In step 812, if the ground connection is normally made, it is determined that the ground interlock condition is OK. Also,
When the earth interlock is OK in step 812, it is confirmed that the location switch 36 is operating normally and that the location switch 36 is ON or OFF (step 513). When the location switch interlock condition is OK in step S13, the next step 814 is executed, and it is confirmed whether the oil type and quantity have been manually set by the control box 33 (step 514). When the preset interlock condition of the control box 33 is OK in step 814, the next step 815 is executed.

In step S15, for example, if an abnormal setting has been made such as a total of 29 failures, a breakage of the loading arm 32, or a failure of the loading arm 32, it is confirmed that the abnormal setting has been reset.

In this way, each item such as each interlock condition and abnormality setting reset is sequentially confirmed, and when all the interlock conditions and abnormality setting reset are OK, loading of oil becomes possible (step 816). Furthermore, the maximum valve 31
A valve opening signal is output to open the stationary valve 31, and the oil level becomes zero.
- shipped to vehicle 25 (step 517);

Note that if the interlock conditions and abnormal setting reset are not OK in steps 812 to 315, loading of oil becomes impossible (step 818).

Incidentally, in step 812, the process shown in FIG. 10 is performed, and the earth interlock conditions will now be explained with reference to FIG. In FIG. 10, it is confirmed that the earth interlock condition is bypassed (step 521). If the grounding is not bypassed in step 821, it is confirmed that the grounding device 36 has grounded and the grounding signal is ON (step 522).

If the ground signal is OK in step 822, the ground interlock is OK (step 523), and the process returns to step 813 shown in FIG. 9 (step 524). Also,
If the ground signal is not ON in step 822, a ground interlock error occurs (step 525), and step 818 shown in FIG. 9 is executed (step 826).
. Here, the above control bag @1 provides a grounding device! 34 failure is set, the ground is bypassed in step 321 and step S22 is skipped to step 8.
23.824 is executed.

Further, when the faulty part of the grounding device 34 etc. is repaired and the product can be shipped normally, the fault setting is canceled by performing the same operation as the fault setting shown in FIG. Also, flow M meter 2
9 or when the cause of damage to the loading arm 32 is resolved, cancel the abnormal setting. .

Therefore, in step 821, the earth interlock is OK without monitoring the earth interlock condition while the operation for canceling the fault setting is executed. For this reason, it is possible to ship the vehicle even if the trolley wheel 25 is not grounded, but in this case, as an emergency measure, the on-vehicle grounding device provided on the trolley wheel 25 may be grounded.

Further, in step 813, the process shown in FIG. 11 is performed, and the location switch interlock conditions will now be explained with reference to FIG.

First, confirm that the interlock condition of the location switch 36 is bypassed (step 531).
. If the location is not bypassed in step 831, the location switch 38 is not malfunctioning, so it is confirmed that the location setting of the main controller 21 is the lane on the right side of the stage where the location switch 36 is turned on (step 532). Next, step 332
If the location setting is the lane on the right side of the stage,
It is confirmed that the location switch 36 is ON (step 533).

If the location switch 36 is ON in step S33, the loading arm 32 is facing toward the set lane, so the location interlock condition is OK (step 534), and step 814 shown in FIG.
The following process is executed (step 535). Further, if the location switch 36 is OFF in step S33, the loading arm 32 is not facing the set lane, so the location interlock is not established (step 836), and the process returns to step 818 shown in FIG. 9, making it impossible to load ( step 537).

Further, when the location setting is set to the lane on the right side of the stage where the location switch 36 is OFF in step 832, it is confirmed that the location switch 36 is OFF (step 838). If the location switch 36 is OFF in step 338, step 8
Since the location setting of 32 and the orientation of loading arm 32 match, the processes of steps 834 and 835 are executed. If the 6-case switch 36 is ON in step 338, the location setting does not match the location setting in step S32, and the process in step $36.837 is executed.

Therefore, if the orientation of the location setting in step S32 and the orientation of the loading arm 32 match, the location interlock is OK. However, if the direction of the location setting and the direction of the loading arm 32 do not match, the loading arm 32 may be rotated to the opposite lane and the shipping start operation may be performed again.

However, if the location switch 36 is out of order and the orientation of the loading arm 32 cannot be detected,
Only one lane can be loaded, and the main control bag wt1 sets a location switch failure and bypasses the location interlock. That is, step S
If location bypass is set in step 31, steps 834 and 835 are executed without executing steps 832, 833 and 838.

Therefore, when the location is bypassed in step 831, the normal location control interlock conditions are not monitored, and the location ink [1] is determined to be OK and shipped. However, in this case, the orientation of the O-ding arm 32 may be adjusted in advance to match the orientation of the location setting.

In this way, the following step S14. Similarly, when S15... is set to failure, each interlock condition and abnormal setting is bypassed and shipping is possible without monitoring.

Effects of the Invention As described above, according to the shipping device of the present invention, the fixed quantity shipping control device at the shipping site can be controlled by remote control in order to bypass the processing of the failure location and perform the next processing by the failure setting operation of the main controller. It is possible to set a fault at any time, and there is no need to go to the shipping site to set the fault each time a fault occurs. In addition, a failure setting signal is sent to each quantitative shipping control device via a communication line, and when the interlock condition is OK, a pump start request signal is sent to the main control device, so that multiple fixed-filtration shipping control devices can be connected to each other. can be centrally managed using a control device in an office or other location. Furthermore, like conventional shipping equipment, there are many bypass switches that are placed on the panel of each quantitative shipping control device at the shipping site.

An error reset switch can be eliminated. That is, since it is not necessary to provide each switch having a pressure-resistant and explosion-proof structure on the panel of the fixed quantity shipping control device, the size of the constant shipping control 4A can be reduced accordingly. Moreover, the bypass switch
It has features such as eliminating failures due to corrosion of the abnormality reset switch and improving reliability.
