Description

Container counter cap

The utility model relates to a kind of container official hats and canopies with tally function, and it counts demonstration by the electrooptical device of inside to the piece granular material that falls into container.

At present existing following container invention: " Vegetable basket with steelyard " (Chinese patent application number: 90203108.2) with function of measuring, " automatically towards the liquid counting chamber " (Chinese patent application number: 89204784.4), " medical operation gauze counting machine " (Chinese patent application number: 92238536.X).More than mostly invention is at special purpose, increases measuring apparatus at container itself.In the middle of medical treatment and industry and commerce production and operation operation, to carry out artificial counting to the piece granular material of container splendid attire often and check; For example medical operating is central to manually checking with the gauze of crossing.Manually check useless power when giving up, number easily miscounts for a long time, finishes the auto inventory counting by electronic installation and can bring a lot of facilities.But the sophisticated electronic circuit is fixed in carrying, cleaning, the sterilization that is unfavorable for container on the container.The vibration that produces during process container also can be shortened electronic circuit, component life.

The purpose of this utility model provides a kind of when splendid attire piece granular material or workpiece advance container, finish and check the number operation automatically, and shows the container counting hat of count value.This device and container are splits, only cover in use on worn-out mouthful of container, are convenient to take off from container, and not overslaugh is to cleaning, sterilization, the carrying of container.The container counting is labeled the part that contacts material and can be pulled down from the hat body easily, and this is beneficial to the cleaning of container counting hat self and reduces pollution, reliable operation.

The purpose of this utility model is achieved in that

Label shell (1) central vertical direction in flat-shaped hollow, offer batching hole, the transparent hole wall that feeds intake (2) with the batching hole concentric, vertical fixing is in labeling shell (1) inside, its hollow square column type hole wall vertically passes the circuit board (5) of horizontal fixed in the hat, and the hat lower bottom cover (2) of center drilling is fixed in labels shell (1) bottom.Be positioned at a side of batching hole wall (3) on the circuit board (5), be arranged with infrared light radiating circuit (7).Many infrared light emitting diodes are uniformly-spaced arranged in this circuit, and beam direction points to the hole wall (3) that feeds intake.Infrared light receiving circuit (8) is arranged on the circuit board of opposite side of the hole wall that feeds intake (3); This side position is relative with infrared light radiating circuit (7) place one side position.Circuit (8) contains the infrared light reception diode with the middle light emitting diode similar number of circuit (7), and this pipe also is uniformly-spaced to be arranged, and light emitting diode in its every the light-receiving end difference alignment circuit (7).Circuit (8) is interior by identical photosensitive multivibrator circuit and Schmidt trigger, constitute independently a plurality of separately photoelectricity receiving element JS1, JS2, JS3, JS4, JS5, JS6, JS7, JS8, their output terminal is electrically coupled to logic trigger circuit (9) respectively, and the buzz circuit that the latter electrically connects on circuit board (10), counting circuit (11), display circuit (12) and battery realize that the counting of paired pulses is explicit with numeral.When the piece granular material dropped into batching hole in proper order, the infrared light wire harness was blocked the count pulse of generation like this, caused the buzzing sound equipment on the one hand, and count pulse is counted and is shown with digital form on the other hand.

By stretching out bolt (17) and the fixing funnel that feeds intake (4) of nut (18) of labeling shell (1) outer surface of upper, have the outlet of enclosing area in the horizontal direction, and its outlet is installed on the top of the hole wall that feeds intake (3) upper port less than the hole wall that feeds intake (3).Funnel (4) is made for non-transparent material.It is pulled down from the hat body through screwing off nut (18) easily.

The container that adopts such scheme is counted official hats and canopies on worn-out mouthful of container, when the piece granular material that pours into certain volume in proper order advances container, just can count hat realization material counting automatically by container at the splendid attire material simultaneously.This will replace manually checks counting operation in medical treatment and the industry and commerce production and operation, and it is counted quick and precisely, and the count value of digital form directly is provided.Counting hat separates with container easily, and funnel is convenient to pull down from the hat body, and these will be convenient to topple over, conveying container, be convenient to the cleaning and sterilizing of funnel and container, prolong the interior circuit lifetime of counting hat simultaneously.The flat-shaped external form of hat body is beneficial to its stable placement.Container counting hat integrates sensing, counting, demonstration, power supply, conveniently moving, and volume is small and exquisite.
