1. since material at every turn from the combination balance aggregate bin to falling into packaging bag, the situation of gathering the during whereabouts is different at every turn, just says also that at every turn it is a variable that last material falls into the required blanking time of packaging bag.If the blanking time that wrapping machine is provided with is short, horizontal sealing material folding situation can take place.In order to prevent to seal material folding, the blanking time must be gathered the poorest situation setting of situation by material.Usually manual observation blanking situation is adjusted the blanking time at the scene, and the blanking time of operated by rotary motion is all long than the blanking time of reality.In fact in most cases, material has fallen into packaging bag fully, but because the blanking time is less than, and horizontal sealing can not start, the waste wait time has influenced package speed.

2. because sporadic indivedual materials rotation situation such as spin in the material dropping process; influence falling speed; even it is long that the blanking time is provided with, one or several materials still might take place do not fall into packaging bag in the time at the blanking of regulation, be sandwiched in sealing part.

In view of the foregoing, we must improve above-mentioned existing mechanism arrangement.

The utility model content

The purpose of this utility model is to provide a kind of computer combination scale that the mechanism of material falling state is provided to wrapping machine, mainly solve existing mechanism the technical matters that wrapping machine seals material folding takes place easily, it provides foundation accurately for wrapping machine starts the horizontal sealing action, improves entire package speed.

The specific embodiment

See also Fig. 1-3, it is a kind of computer combination scale of the utility model provides a structural representation from the mechanism of material falling state to wrapping machine.As shown in the figure: it comprises the light-transmitting materials blanking elephant trunk 2 between the feeding mouth of the discharging opening that is arranged on combination balance 1 aggregate bin and wrapping machine 5, described blanking elephant trunk 2 both sides are equipped with the optical fiber transducer 3 that surveyed area covers blanking elephant trunk diameter, the blanking signal output part of described optical fiber transducer 3 is connected to the signal input part of a controller 4, and the control signal output ends of this controller 4 is connected to the signal input end of wrapping machine 5.Described optical fiber transducer 3 and controller 4 all are arranged on the combination balance 1.

Optical fiber transducer 3 can adopt zone detection, the light transmission type optical fiber transducer of Japanese Keyemce (KEYENCE) company, overlay area 40mm, if blanking elephant trunk diameter surpasses 40mm, can adopt many groups and usefulness, only accomplish to cover fully the blanking elephant trunk, just can detect all materials by the blanking elephant trunk.

Controller 4 can adopt has the FX of Mitsubishi series of PLC, utilizes the interrupt function of PLC, in time receives the signal of optical fiber transducer.Use the high-speed counting function of PLC, accurately calculate material by optical fiber transducer time and pitch time.And control signal issued wrapping machine by high speed output or communication port.

During use, light-transmitting materials blanking elephant trunk 2 connects combination balance 1 and wrapping machine 5, and material w falls into the packaging bag of wrapping machine 5 by blanking elephant trunk 2.Infiltration type area light fiber sensor 3 assemblies are installed in blanking elephant trunk 2 both sides, and the surveyed area of optical fiber transducer 3 will cover the diameter of blanking elephant trunk 2, can both be detected with assurance all materials by blanking elephant trunk 2.When material W passed through, optical fiber transducer 3 was to controller 4 output high level signals.After controller 4 is handled calculation to the received signal, the blanking time is fed back to wrapping machine 5 by I/O signal or communication modes, wrapping machine 5 can accurately start horizontal sealing.

The response time of optical fiber transducer 3 is 33 μ m, for the material from the free fall of combination balance aggregate bin, as long as article diameters can accurately detect passage period greater than 0.4mm.

Because material is from the free fall of set bucket, particle not all during the whereabouts is all got together, and individual other particle can scatter, so " blanking signal " that optical fiber transducer detects has the fitfull pulse when beginning and end and occur.As " the blanking signal " among Fig. 4.Controller will be handled signal, judges first material that arrives and last material that passes through, and calculates the pitch time t1 of material passage period t2 and adjacent blanking.

As shown in Figure 4: after computer combination scale 1 is received wrapping machine request blowing signal, open aggregate bin and discharge material, the blanking situation with material feeds back to wrapping machine 5 in 2 kinds of modes simultaneously.

Mode 1: when opening aggregate bin discharge material, to wrapping machine output " blowing " level signal.When controller judged that last material passes through, " blowing " signal resetted.The positive rise of " blowing " signal that detecting device is arranged among Fig. 3 is the moment that the set bucket is opened, and the falling edge of " blowing " signal is the moment of last material by optical fiber transducer.

Wrapping machine is received the positive rise of " blowing " signal, begins to draw a series of actions such as bag, when receiving the falling edge of " blowing " signal, can begin horizontal sealing immediately, and material just all falls into packaging bag.

Mode 2: open aggregate bin and discharge material, simultaneously to wrapping machine output " blowing " impulse singla.The notification package discharge of installing.And by communication interface to wrapping machine outputting material passage period t2.Wrapping machine calculates the horizontal sealing time opening according to the time t2 that receives.Can reach the effect of mode 1 equally.

Mode chart from Fig. 3 is as can be seen: the blowing delay time t3 of no detecting device (as prior art) is the fixed value that presets, and after blanking is finished, has waited for the t4 time again, and wrapping machine just begins horizontal sealing.

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
