The injection molding machines can be mounted to the greatest extent by fully utilizing the conventional power grid, so that the whole power grid cannot be overloaded and tripped out, safety production and the safe operation of the equipment are ensured, and the yield of a product is improved to the greatest extent; simultaneously, whether the power grid is in a saturated operation state or not can be clearly judged through the background computer.
Description
Technical field
What the present invention relates to is the plastic-injection moulding machine in control fields such as a kind of plastic injection equipment tool that is applicable to electromechanical integration, rubber processing equipment or electric power and the power dispatching system of rubber processing equipment.
Background technology
For a concrete grid nodes, the power capacity of its output is limited, and therefore the high-power electric appliance number of devices that connects has certain limit, otherwise the situation that will trip, cause the equipment can't operate as normal even damage expensive electric equipment, have a strong impact on industrial production.And increase electrical network capacity need through examine for a long time, hundreds of thousands is up to a million at most at least for expense, transforms relatively difficulty of electrical network concerning rural one-level grass-roots unit.
One 100 kilowatts electrical network can only use 5 20 kilowatts plastic-injection moulding machine (being designated hereinafter simply as " injection machine ") in theory at most, can't allow the injection machine more than 6 work simultaneously by normal situation.Improving output also cannot.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of work of counting many injection machines of dynamic dispatching according to the platform of the capacity of electrical network and injection machine by background computer, injection, the plastic-injection moulding machine of storing action phase or electric power and the power dispatching system of rubber processing equipment of the control injection machine of staggering the time.
The objective of the invention is to finish by following technical solution: it mainly includes a background computer, this background computer is connected with the plastic-injection moulding machine more than 2 at least, this plastic-injection moulding machine and background computer by industry ethernet in parallel mutually communication connect; The power output end of this plastic-injection moulding machine is connected with the three-phase alternating current electrical interface, to the electric equipment power scheduling used or the power division control technology of staggering the time in real time.
Described industry ethernet also can be replaced by other interfaces such as CAN, RS485, RS232; The separate unit injection machine must possess the ability of calculating current how much power of autophage.
The present invention utilizes background computer to pass through other interfaces such as industry ethernet or CAN, RS485, RS232 and realizes that with many injection machines communications are connected, the work that computer is counted many injection machines of dynamic dispatching according to the platform of the capacity of electrical network and injection machine, stagger the time and control injection, the storing action phase of injection machine, take full advantage of existing electrical network and articulate injection machine to greatest extent, thereby guarantee whole electrical network nonoverload, do not trip, guarantee the safe handling of safety in production and equipment, also improved product yield to greatest extent; Can understand electrical network clearly by computer simultaneously and whether be in saturated.
Description of drawings
Fig. 1 is background computer of the present invention and many injection machine Ethernet connection layouts.
Fig. 2 is the consumed power schematic diagram of a work period of separate unit injection machine of the present invention.
Fig. 3 be under the perfect condition of the present invention two injection machines stagger the time control and synthetic after the power schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done detailed introduction: shown in Figure 1, the present invention mainly includes a background computer 1, this background computer 1 is connected with plastic-injection moulding machine 2 or the rubber processing equipment more than 2 at least, this plastic-injection moulding machine 2 or rubber processing equipment and background computer 1 by industry ethernet 4 in parallel mutually communication connect; The power output end of this plastic-injection moulding machine 2 or rubber processing equipment is connected with three-phase alternating current 3 interfaces, to the electric equipment power scheduling used or the power division control technology of staggering the time in real time.Described industry ethernet 4 also can be replaced by other interfaces such as CAN, RS485, RS232.Separate unit injection machine 2 or rubber processing equipment must possess the ability of calculating current how much power of autophage.
Shown in Figure 2, the substantially relevant mould of the one-period of injection machine work of the present invention, injection, storing, die sinking, 5 action phase of thimble, the working time of each action phase, consumed power are different.The maximum period of consumed power is in injection, storing stage among the figure, as long as can realize that many injection machines are injected, storing stage electric power are staggered the time control, and one 100 kilowatts the electrical network injection machine more than 6 of just can working simultaneously so.
Operation principle of the present invention: the synthetic power sum of injection machine of supposing all works at present is Wd, and the injection of separate unit injection machine, the required power of storing are Wc, and the general power of electrical network output is Wp.The current consumed power of every injection machine of background computer wheel continuous query in the course of work, the current consumed power addition of all injection machines is obtained Wd, whether at once simultaneous computer also each injection machine of poll will enter the duty of injection, if an injection machine will enter the duty of injection at once, computer carries out following computing: if Wd+Wc 〉=Wp then temporarily stop injection machine action just allows this injection machine to enter injection, storing stage behind Wd+Wc≤Wp to be satisfied.So all can reach a work poised state through tens all injection machines in back that move in circles, guarantee all injection moulding function steady operations and be no more than the heap(ed) capacity of electrical network, utilize existing electrical network to improve output to greatest extent.
Every injection machine sends the operating efficiency of injection machine itself (working time of a circulation deducts after standby time the percentage divided by the working time of a circulation again) to computer after through a working cycles, and computer calculates the overall operating efficiency of all injection machines and maximum consumption power.
When maximum consumption power is on the low side near the overall operating efficiency of the peak power output of electrical network and injection machine, illustrate that the fan-out capability of electrical network is not enough, number of devices is on the high side, and solution is to transform electrical network or remove equipment component.When maximum consumption power is not higher near the overall operating efficiency of the peak power output of electrical network and injection machine, illustrate that the power output of electrical network is enough, can also by interpolation equipment improve electrical network utilization rate, improve the output of product.
Even the injection machine quantity that employing plastic-injection moulding machine electric power and power dispatching system purpose are electrical networks to be connect is too much, also can guarantee whole electrical network nonoverload, not trip, guarantee the safe handling of safety in production and equipment, also improved product yield to greatest extent.Can understand electrical network clearly by computer simultaneously and whether be in saturated.
