A kind of monitoring arrangement of integrated production line, production line include the facility of at least two independent runnings, and conveying device or mechanical arm between between these two facility; This monitoring arrangement includes a control circuit that is preset in these facility respectively, one in order to receive by the computer of this control circuit output signal respectively, be provided with a respectively CPU of this control circuit output signal of conversion in the computer, a display is connected with this computer, shows the signal by this CPU output.

In addition, this production line includes at least one peripheral device, and a detector is located at the suitable position of this peripheral device.

Adopt said method and device, when respectively these facility produce abnormality in operation process, the signal that shows this abnormality can be passed to this computer, and after confirming this abnormality by operating personnel, whether decision sends instruction so that unusual facility shut down, and makes these operating personnel can monitor respectively these facility easily by this, and, the still continuous running independently of facility of abnormality does not take place, and interrupts so that this production line is unlikely completely.

Description of drawings

Below in conjunction with accompanying drawing the present invention is further described.

Fig. 1 is the utilization constitutional diagram that the present invention waits upon embodiment most.

Embodiment

Seeing also Fig. 1, is example to make PET bottle, and the method for monitoring of integrated production line that the present invention takes off and the utilization state of device are described.

By in the manufacture process of a PET bottle, consist predominantly of following some steps:

A. import in an amount of raw material to a Jet forming machine 10, make some bottles of embryos with injection molding method;

B. an amount of bottle embryo is delivered in the bottleneck crystallization machine 20,, promotes its intensity being heated in its bottleneck position;

C. with an amount of bottleneck crystallization the bottle embryo be delivered in the bottle blowing machine 30, with it is heated one by one, the inflation supervisor, to make PET bottle with reservation shape.

In aforesaid PET bottle manufacture process, except that respectively this Jet forming machine 10 that is provided with in regular turn, bottleneck crystallization machine 20 and bottle blowing machine 30, other has a conveying device 40 to be located at respectively between this Jet forming machine 10 and bottleneck crystallization machine 20, in order to the bottle embryo is delivered to this bottleneck crystallization machine 20, this bottle embryo is a finished product with respect to this Jet forming machine 10 in this process, but is raw material with respect to 20 in this bottleneck crystallization machine; One mechanical arm 50 is located at respectively between this bottleneck crystallization machine 20 and bottle blowing machine 30, each bottle embryo of bottleneck crystallization is delivered in this bottle blowing machine 30, in this process respectively this bottleneck crystallization the bottle embryo be finished product with respect to this crystallizer 20, be raw material with respect to 30 of this bottle blowing machines.

In the aforementioned manufacturing process, respectively this Jet forming machine 10, bottleneck crystallization machine 20 are main production equipments with bottle blowing machine 30, respectively this conveying device 40 is the processing procedure connected device with mechanical arm 50, needs to cooperate some peripheries to be equipped with in the utilization of reality, so that its running is more smooth.For example: one first peripheral device 60, one second peripheral device 70 and the cooling tower 80 that are connected with aforementioned respectively these facility with suitable pipeline (not shown).This first peripheral device 60 includes a High Pressure Air Compressor, a low pressure air compressor and the refrigerating machine etc. that power source is provided, and this second peripheral device 70 then includes dehumidifying heat pump and blank bottle mold temperature machine etc.

Aforesaid respectively this Jet forming machine 10, bottleneck crystallization machine 20 and bottle blowing machine 30 etc. are mainly made facility, are respectively equipped with the control circuit of tool CPU on it, and this control circuit has the failure warning loop respectively; And respectively should make on the suitable position of facility, connected device and peripheral equipment, be respectively equipped with in order to detecting several detector (not shown) of its operating condition or situation (for example whether pressure or temperature are in secure setting), and respectively this detector can convert detecting gained information to digital signals output.

One computer 90 is located at suitable place, and these manufacturing facility, peripheral equipment are connected respectively with respectively to pass through some circuits, especially its inner set CPU is for receiving the signal of the representative operation conditioned disjunction state of being exported by this failure warning loop and detector, and will be respectively this signal be converted to numeral, symbol or literal, be shown in a display that computer 90 is connected on.The operator can read from this display: the issuing velocity of this Jet forming machine 10, pressure and accumulated quantity; The cooling water channel temperature of this bottleneck crystallization machine 20, Tc; The heating cabinet temperature of this bottle blowing machine 30, pre-blowing time, gassing time, evacuation time and represent cycling time of its production message and accumulated quantity etc.; Particularly can read facility that abnormality takes place with and the position or the state of abnormal case, and confirm this situation with conversational mode, by a keyboard or panel output one instruction, these facility that order produces abnormality shut down.

Aforesaid respectively this manufacturing facility system is made as can independently working person; therefore; when facility wherein; for example Jet forming machine 10 is accepted instruction and when shutting down; respectively this bottleneck crystallization machine 20 still can continue running; continue to be delivered to these bottleneck crystallization machine 20 places and give crystallization with the bottle embryo that will be temporary on this conveying device 40; to the bottle embryo that crystallization is finished simultaneously; be transferred to these bottle blowing machine 30 places and be shaped, use this ability of life that makes whole production line and be unlikely because of the fault of this Jet forming machine 10 shut-down completely.And, when respectively this bottleneck crystallization machine 20 continues running with bottle blowing machine 30,, can form a complete production line once again with bottle blowing machine 30 with this crystallizer 20 respectively at once in case the operator restarts after getting rid of the failure cause of this Jet forming machine 10.As for this peripheral device respectively; for example cooling tower 80 is because it is while and respectively this manufacturing facility binding use; therefore it is not made as and shuts down simultaneously, make it provide suitable refrigerating function, to keep normal operation to other manufacturing facility that still continue running with any manufacturing facility.
