Description

Negative-pressure vacuum switching mechanism

Technical field

The utility model is related to switching mechanism, particularly to a kind of negative-pressure vacuum switching mechanism for floor upset, belongs to In floor production equipment technical field.

Background technology

With the proposition of industrial 4.0 concepts, floor production industry is also progressively implementing automated production.For example German shellfish is high The floor production line equipment producing just employs the automatic turning operation that floor realized by negative-pressure vacuum switching mechanism, its operation principle It is vacuum generator principle, the one kind producing negative pressure using malleation source of the gas is new, efficiently, cleaning, economical, small-sized vacuum is first Part so that in the place having compressed air, or simultaneously need to the local negative pressure that obtains of positive/negative-pressure becomes very in pneumatic system Easily and convenient, machinery in industrial automation, electronics, packaging, printing, the field such as plastics and robot has obtained extensively should With.

Because the negative-pressure vacuum switching mechanism on existing floor production line is with vacuum generator as power source, absorption affinity has Limit, and the Multivariate influence by existing timber kind, its performance and flatness have differences, and easily form air leakage point, lead to adsorb Suction often occurs not enough during floor, the problems such as easily dropping during upset floor.

In addition, using placement (fall plate) speed behind vacuum generator upset floor slow (negative pressure nature removal, fall plate automatically), Noise is big, wastes compressed air.

Utility model content

The defect existing for negative-pressure vacuum panel turnover mechanism on existing floor production line, the purpose of this utility model is to carry For a kind of improved negative-pressure vacuum switching mechanism, solve the defect that prior art exists.

The utility model employs following technical proposals: discloses a kind of negative-pressure vacuum switching mechanism, including compressed air Source, the reversal valve being connected with described compressed air source pipeline, the sucker being connected with described reversal valve pipeline and vavuum pump, Yi Jiyu Described compressed air source pipeline connects successively controlling switch, electric control reversing valve and cylinder, described controlling switch controls compression Air-source enters the opening and closing of pipeline, and described electric control reversing valve is opened by phased manner under the control of control circuit or closed Close compressed air and enter reversal valve, described cylinder controls reversal valve to carry out commutation action.

Specifically, described cylinder is two, is connected to the two ends of reversal valve respectively by pipeline.

Specifically, described vavuum pump is connected with pressure regulator valve.

Specifically, described sucker is on multiple pipelines being connected to side by side and being drawn by reversal valve.

The beneficial effects of the utility model are: provide a kind of negative-pressure vacuum switching mechanism, overcome existing vacuum and send out When raw device principle switching mechanism has suction deficiency, upset, workpiece easily drops, and places speed slowly, noise is big after upset, compresses empty Gas consumes big defect.

Brief description

In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below will be to embodiment In description the accompanying drawing of required use be briefly described it should be apparent that, drawings in the following description are only that this practicality is new Some embodiments of type, for those of ordinary skill in the art, on the premise of not paying creative work, can also root Obtain other equivalent or similar technical schemes according to these accompanying drawings.In the accompanying drawings:

Fig. 1 is the structural representation of negative-pressure vacuum switching mechanism used in existing equipment.

Fig. 2 is the structural representation of negative-pressure vacuum switching mechanism disclosed in the utility model.

Specific embodiment

In order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, the utility model is present To be described more fully hereinafter with reference to the accompanying drawing illustrating the utility model embodiment.However, the utility model can be with a lot Multi-form embodies and should not be construed as being limited to specific embodiment set forth herein.On the contrary, these embodiments carry Supply is skilled artisan understands that the technical solution of the utility model.For those of ordinary skill in the art, do not paying On the premise of going out creative work, other similar or equivalent technical schemes can also be obtained according to these accompanying drawings.

Unless otherwise defined, term (comprising scientific and technical terminology) used herein above should be construed to have as the utility model The identical meaning that person of ordinary skill in the field is commonly understood by.It will also be understood that term used herein above should It is construed to that there is the consistent meaning of the meaning in the content of this specification and correlation technique with them, and should be not manage Wanting or excessive form are explained, unless expressly so limited here.

With reference to Fig. 1, it is the structural representation of the floor switching mechanism on existing floor production equipment line, compressed air source warp After controlling switch 016, each branch vacuum generator 012 is connected with pipeline 011, each vacuum generator connects silencer 013, turns over Plate sucker 015 is connected with vacuum generator 012 pipeline, after opening compressed air controlling switch 016, a large amount of in compressed air moment During by vacuum generator 012, negative pressure will be produced at turnover panel sucker and hold floor 014, upset will close compressed air behind floor Controlling switch 016, then the naturally slow removal of the negative pressure at turnover panel sucker, naturally drop to reach under gravity and turn in floor 014 Turn purpose.

With reference to Fig. 2, it is the structural representation of negative-pressure vacuum switching mechanism disclosed in the utility model, including compressed air Source, the controlling switch 029 being connected with described compressed air source successively pipeline 023, electric control reversing valve 021 and cylinder 022, pipeline is even Connect the reversal valve 024 of described cylinder 022, the sucker 026 being connected with described reversal valve 024 pipeline and vavuum pump 027, described is true It is connected with pressure regulator valve 028 on empty pump 027.Wherein, controlling switch 029 be used for control compressed air enter pipeline 023 unlatching and Close, electric control reversing valve 021 changes flow direction in pipeline 023 for the compressed air, cylinder 022 under the control of logic control circuit Effect be to pull reversal valve 024 to carry out commutation action, the purpose of two cylinders of design is to increase the stability of commutation action, changes It is high flow directional control valve to valve 024, energy moment, by substantial amounts of air stream, makes to form negative pressure in reversal valve 024 chamber, improves machinery Efficiency.Under the suction function that vavuum pump 027 produces, sucker 026 holds floor and is overturn, and upset terminates rear electric control reversing valve 021 unlatching, the compressed air negative pressure that the interior reduction vavuum pump 027 of 023 entrance reversal valve 024 produces at sucker 026 by the road, from And realize quickly dropping of floor 025.

Although the utility model here is carried out with reference to specific aspect of the present utility model, feature and exemplary embodiment Description is not it should be appreciated that purposes of the present utility model therefore suffers from limiting, but extends and cover numerous others Change, modification and alternate embodiment, as given the utility model those skilled in the art institute based on disclosure herein Hint.Correspondingly, all of the present utility model spirit and principle within, any modification, equivalent substitution and improvement done etc., Should be included within protection domain of the present utility model.
