Description

  The present invention relates to an energy saving monitoring apparatus and an energy saving monitoring method for monitoring an energy saving implementation status in a gravure printing machine or the like.

  A gravure printing machine is known as one of printing materials. In order to operate the gravure printing machine, power, compressed air, steam, cooling water, etc. are required as energy.

  However, measuring instruments such as electric power, compressed air, steam, and cooling water used in a printing press are expensive, and a system for grasping the energy consumption as described above is also expensive. For this reason, it is difficult to permanently install them for each printing press, and they are often installed for each floor of the building and for each building. For this reason, it is difficult to grasp the amount of energy consumption reduction when energy saving is performed by one printing press to improve energy consumption efficiency (reduction of energy consumption). In addition, there is a problem that it is difficult to realize the reduced effect, such as how much the amount is effective, and energy saving is not continuously performed.

Based on this, it is preferable to further calculate an effect amount that represents the amount of energy reduction resulting from the energy saving implementation, and the display unit further displays the effect amount.
In addition, it is desirable that the arithmetic processing unit performs integration for each count of the input time when calculating the value, and the display unit displays the integrated value in real time.

In FIG. After selecting the type, the amount of reduction can be set by selecting the “Increase” button 853 and “Decrease” button 854 in the numerical value setting section 852 in which five digital switches are arranged and can be set from 0.00 to 999.999.

At the time of display, a lamp 877 corresponding to “Yen” at the time of displaying various energy units or effect amounts is turned on.

  The energy saving monitoring device 7 is not limited to this. For example, the number of digits and the display value in the energy reduction amount / effect amount display unit 87, the energy reduction amount setting unit 85 per unit time, and the energy price setting unit 86 per unit amount. The range of the set value may be changed, or each unit may be configured as a touch panel.

  Next, the flow of the energy saving monitoring method using the energy saving monitoring device 7 will be described with reference to FIG.

  In the energy saving monitoring method of the present embodiment, supply paths for power, compressed air, steam, cooling water, etc., for the gravure printing machine 1 while predetermined energy saving is performed in advance and energy consumption efficiency is improved. Reading the indicated value of the measuring instrument temporarily installed at a predetermined location of, and grasp the difference between the usual energy consumption and the energy consumption during energy saving. At this time, the amount of reduction of each energy is grasped by measuring instruments provided at one or a plurality of locations according to the type of energy to be reduced when energy saving is performed. The measuring instrument may be a permanent instrument.

  In the gravure printing machine 1, power, compressed air, steam, and cooling water from each supply source are branched and supplied to various parts of the gravure printing machine 1 on the way. By providing the measuring instrument before branching the supply path, the gravure printing machine 1 as a whole measures the amount of energy consumed and grasps the amount of reduction during energy saving. However, the measurement is not limited to this, and the measurement may be performed at various points in the printing press.

  As an example of energy-saving implementation, if a human sensor is provided at a predetermined location of the gravure printing machine 1 and the human sensor does not detect that there is a person at that location during printing by the gravure printing machine 1, Assume that the light is turned off. At this time, by attaching a measuring instrument to the wiring for power supply by the power (auxiliary machine 200V) 42 or the power (auxiliary machine 100V) 43 and reading the indicated value, Know the difference in energy consumption per unit time (energy reduction).

  After grasping the amount of energy reduction, the sequencer 5 of the gravure printing machine 1 and the signal input unit 72 (signal input unit 82) of the energy saving monitoring device 7 are connected by a signal line, and as shown in FIG. The energy reduction amount per unit time and the energy price per unit amount obtained by performing the above measurement are set and input (S01).

For example, when the energy consumption efficiency is improved from the result of reading the indicated value of the measuring instrument at the time of energy saving, the power consumption per unit time (for example, 1 minute) is reduced by 0.7 kwh for the power 42 of the auxiliary machine 200V. If it is found that this is done, this is set and input by the energy reduction amount setting unit 85. In addition, an energy price per unit amount per power 42, for example, power: 10 yen / kwh is set and input by the energy price setting unit 86.
When energy savings are performed for a plurality of energy sources, the amount of energy reduction per unit time is grasped for each of the corresponding types of energy, and set and input together with the energy price. For example, when it is found that the consumption per unit time is reduced by 2.3 kg for the steam 45 together with the electric power 42, the reduction amount and the energy per unit amount for the steam 45 are also calculated. Set and input a price, for example, 4.2 yen / kg.

  Then, the operation of the gravure printing machine 1 is started, and the integration start button 874 of the energy saving monitoring device 7 is pressed, and the energy saving monitoring device 7 starts calculating the energy reduction amount and the effect amount (S02).

  Here, in the gravure printing machine 1, when it is detected by the sequencer 5 that energy saving has been carried out (measured and grasped in advance by the amount of energy reduction per unit time), an energy saving execution signal indicating this. Is output from the sequencer 5 to the energy saving monitoring device 7.

For example, as described above, when the gravure printing machine 1 is provided with a human sensor and an unnecessary electric lamp is turned off during printing, the electric lamp is turned off when printing is in progress and the human sensor is OFF. Is detected by the sequencer 5, a no-voltage signal is output to the energy saving monitoring device 7 as an energy saving execution signal indicating this.
The fact that printing is in progress can be detected, for example, by inputting a rotation signal indicating that the plate cylinder is rotating to the sequencer 5, which indicates a predetermined number of rotations that is not 0, and the human sensor is OFF. When a signal indicating that it is present is input to the sequencer 5, it can be detected that the above energy saving is being performed. In such a case, the no-voltage signal is output from the sequencer 5 to the energy saving monitoring device 7. The energy saving execution signal is not limited to a no-voltage signal, and can be determined as appropriate.
The output source of the energy saving execution signal is the sequencer 5, but is not limited to this, and any device can be used as long as it can detect that energy saving is being performed and can output a predetermined signal to the energy saving execution device 7 at the time of detection. .

When the energy saving execution signal is input via the signal input unit 72 (S03; YES), the storage / calculation processing unit 73 of the energy saving monitoring device 7 counts the input time of the signal per unit time (S04), Based on the input time, the energy reduction amount per unit time, and the energy price per unit amount, the energy reduction amount and the effect amount due to the energy saving are calculated (S05).
In S05, the energy reduction amount per unit time is integrated every count. Similarly, for each count, the amount of energy reduction per unit time multiplied by the energy price per unit amount (per unit time) is also integrated, and the display unit 74 (energy reduction amount / effect It is displayed on the amount display part 87) (S06). During the energy saving, the energy reduction amount or the effect amount displayed on the display unit 74 increases. If the zero reset button 876 is pressed during the calculation process of S05, the integration is restarted from 0.

  When the energy saving execution signal is not input (S03; NO), the energy saving monitoring device 7 does not count, and the display on the display unit 74 remains the energy reduction amount or the effect amount.

Until the processing is completed by pressing the integration stop button 875 of the energy saving monitoring device 7 (S07; NO), the above S03 to S06 are repeated, and the energy saving monitoring processing is ended by pressing the integration stop button 875 (S07; YES).
In this way, the gravure printing machine 1 grasps the implementation status of energy saving. For example, if it can be confirmed that the improvement is continuously performed, the energy saving monitoring device 7 can be detached and attached to another gravure printing machine 1 to monitor the energy saving for a plurality of printing machines.

  In addition, although the example which light-extinguishes the light of an unnecessary location using the human sensitive sensor was given as an example of implementation of energy saving above, it is not restricted to this.

For example, as another energy-saving implementation, the supply of cooling water used for a cooling roller or the like for cooling the printed material is stopped (temporarily) when printing is temporarily stopped, such as during color matching of the printed material. You can also. Also in this case, the amount of energy reduced per unit time when the energy saving is performed (when the cooling water supply is stopped) is previously grasped by the measuring instrument, and the energy saving amount per unit time is stored in the energy saving monitoring device 7. Enter the energy price per unit amount. In this case, as energy, the amount of water and electric power used for cooling water and transporting cooling water is reduced, so the amount of energy saved during energy saving is ascertained and entered together with the energy price. Keep it.
In the above S03, for example, when the sequencer 5 detects that printing is temporarily stopped and the supply of cooling water is stopped, the above energy saving is performed. An energy saving execution signal may be output to the energy saving monitoring device 7.

  As described above, according to the present embodiment, the amount of energy to be reduced and the energy price at the time of energy saving in the gravure printing machine 1 are set and input in advance to the energy saving monitoring device 7 for each energy to be reduced. Then, the energy saving monitoring device 7 is connected to the sequencer 5 of the gravure printing machine 1. When the sequencer 5 detects that the above energy saving operation is being performed, an energy saving execution signal indicating this is input from the sequencer 5 to the energy saving monitoring device 7. The energy saving monitoring device 7 counts the input time of the energy saving execution signal, calculates and displays the energy saving amount and the effect amount at the time of energy saving based on the input time, the energy reduction amount per unit time and the energy price per unit amount. .

As a result, when the gravure printing machine 1 saves energy and improves the energy consumption efficiency, the amount of energy reduction can be easily grasped. Further, the energy saving monitoring device 7 can be configured as a single small device and only needs to be connected to the sequencer 5, so that it can be easily attached to and detached from the printing press. Even when the number of printing presses is large, it is possible to easily grasp the status of efforts to improve energy consumption efficiency for each printing press by repeatedly mounting and removing.
In addition, energy consumption measuring instruments, etc. are only necessary when grasping the energy reduction amount per unit time in advance, and are not necessary for measuring the energy reduction amount during the subsequent energy savings. It is not necessary to install a measuring instrument for monitoring, the cost can be reduced, and the application is easy even when the number of printing machines is large.

Furthermore, how much the amount of energy reduction can be realized as an amount of money can be realized by displaying the amount of effect, which is a motivation for continuous energy saving.
Further, by displaying the integrated value of the energy reduction amount or the like in real time, the current energy reduction status can be quickly grasped.

  In the present embodiment, an example in which the energy saving monitoring device 7 is attached to the gravure printing machine 1 is shown. However, the present invention is not limited to this. The same can be applied to a web material processing apparatus, for example, a web offset press, a coating line using a coater, or the like. The energy saving monitoring device 7 may be connected to a sequencer or the like of each device, and the energy reduction amount and effect amount at the time of energy saving may be calculated and displayed in the same procedure.

  The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these naturally belong to the technical scope of the present invention.
