Summary of the invention
The technical problem to be solved in the present invention is to provide one kind to open a bag filling control method, completely open in detection sack
In the case of, then fill operations are carried out, it packs material in scale hooper and is filled into packaging bag completely, improve the qualification of packaging product
Rate.
One kind opening a bag filling control method, specifically includes following steps:
(1), first the packaging bag of non-opened mouth is placed on the support bag plate below scale hooper, scale hooper discharge outlet is set
Be equipped with photoelectric sensor on a circle, hold in the palm and be provided with photoelectric sensor under a circle on bag plate upper surface, at this time upper photoelectric sensor and
The signal communication of lower photoelectric sensor;
(2), controller control bag openning body starting to the sack of packaging bag carry out out bag operation, when open bag operation complete
Afterwards, controller acquires the signal communication state of upper photoelectric sensor and lower photoelectric sensor, when the sack of packaging bag fully opens
When, lower photoelectric sensor is blocked in packaging bag, and packaging bag is worked as in the photosignal cutting of upper photoelectric sensor and lower photoelectric sensor
Sack when being not turned on or opening incomplete, upper photoelectric sensor and lower photoelectric sensor remain signal communication state;
(3), when the photosignal cutting of controller acquisition, controller controls sawing sheet valve and opens, the object in scale hooper
Material is filled into packaging bag bag.
When the photosignal that the controller acquires is always connected state, the folder of controller control support bag plate side
Bag mechanism sack is not turned on or is opened incomplete packaging bag press from both sides to recycling conveyer belt on recycle.
After the discharge valve opening is filling, the filling of the weighing sensor sensor acquisition packaging bag on bag plate is held in the palm
Filling weight, when filling weight qualification, controller controls bag-clamping mechanism and presss from both sides canned packaging bag to sealing conveyer belt, into
The sealing operation of row next step, when sense weight is unqualified, controller control discharge valve opening carries out supplement tank material, until
Weight is qualified.
The technical scheme is that:
Advantages of the present invention:
The case where present invention is opened using photoelectric sensor induction sack is not placed in support bag plate or packaging bag in packaging bag
In the case where not fully opening, upper and lower photoelectric sensor is the state of connection, the discharge valve of the scale hooper of controller control at this time
It closes, without fill operations, only when sack fully opens, lower photoelectric sensor is blocked in packaging bag, upper and lower photoelectric sensing
When device photosignal disconnects, the discharge valve that controller controls scale hooper is opened, and is carried out fill operations, is guaranteed the discharging of scale hooper
Mouth alignment pocket progress is filling, guarantees that whole material-fillings enter in packaging bag;Bag-clamping mechanism of the invention is connect with controller,
Such packaging bag is pressed from both sides to recycling conveyer belt, is recycled by the case where packaging bag is not switched on or does not fully open, bag-clamping mechanism,
Guarantee postorder packaging bag smoothly opens bag and filling;Whether weighing sensor of the invention incudes filling weight qualified, works as conjunction
When lattice, controller controls bag-clamping mechanism and presss from both sides canned packaging bag to sealing conveyer belt, carries out the sealing operation of next step,
When sense weight is unqualified, controller control discharge valve opening carries out supplement tank amount, until weight is qualified.
Specific embodiment
See Fig. 1, one kind opening a bag filling control method, specifically includes following steps:
(1), first the packaging bag of non-opened mouth is placed on the support bag plate below scale hooper, scale hooper discharge outlet is set
It is equipped with photoelectric sensor 2 on a circle, holds in the palm and is provided with photoelectric sensor 3 under a circle on bag plate upper surface, at this time upper photoelectric sensor 2
With the signal communication of lower photoelectric sensor 3;
(2), controller 7 control bag openning body 4 starting to the sack of packaging bag carry out out bag operation, when open bag operation complete
Afterwards, controller 7 acquires the signal communication state of upper photoelectric sensor 2 and lower photoelectric sensor 3, when the sack of packaging bag is beaten completely
When opening, lower photoelectric sensor 3 is blocked in packaging bag, the photosignal cutting of upper photoelectric sensor 2 and lower photoelectric sensor 3, when
When the sack of packaging bag is not turned on or opens incomplete, upper photoelectric sensor 2 and lower photoelectric sensor 3 remain that signal connects
Logical state;
(3), when the photosignal cutting that controller 7 acquires, controller 7 controls sawing sheet valve 1 and opens, in scale hooper
Material-filling enters in packaging bag bag;When the photosignal that controller 7 acquires is always connected state, the control support bag of controller 7
The bag-clamping mechanism 5 of plate side sack is not turned on or is opened incomplete packaging bag press from both sides to recycling conveyer belt on recycle;
(4), it is filling after, hold in the palm bag plate on 6 sensor of weighing sensor acquisition packaging bag filling weight, it is filling
When weight qualification, controller 7 controls bag-clamping mechanism 5 and presss from both sides canned packaging bag to sealing conveyer belt, carries out next step
Sealing operation, when sense weight is unqualified, controller 7 controls the opening of discharge valve 1 and carries out supplement tank material, until weight is closed
Lattice.
