The operation principle to volume measurement device is illustrated below.When measuring the size of article, staff is by article The porch of transfer station 2 is placed on, transfer station 2 conveys article to sensor position.When article does not reach sensor Test position when, each photoreceptor 121 of the light-receiving component 1 of sensor receives the light of the light source transmitting of light source assembly 4, light All photoreceptors 121 of receiving unit 1 export the electric signal of setting, such as, high level；When article is along the forward position of conveying direction When reaching the test position of sensor, the part light launched by light source is blocked by article, the part photoreceptor of light-receiving component 1 121 light that can not receive light source transmitting, can receive the photoreceptor 121 and the light that can not receive light source transmitting of the light of light source transmitting Photoreceptor 121 export different electric signals, such as, and can receive light source transmitting light photoreceptor 121 output high level, no The output low level of photoreceptor 121 of the light of light source transmitting can be received, the control module of volume measurement device can be according to continuously quilt Centre distance between the number and two neighboring photoreceptor 121 of the photoreceptor 121 for blocking calculate article along photoreceptor 121 The size of orientation.In the present embodiment, being blocked according to the photoreceptor 121 of the light-receiving component 1 of first sensor Situation calculates the height of article, and the situation that is blocked of the photoreceptor 121 of the light-receiving component 1 according to second sensor calculates article Width.

Further, control module is detected and recorded and once passes when transfer station 2 often conveys article one minimum range of movement Sensor each photoreceptor 121 output electric signal, when article from first to last by the test position of sensor when, control module The output valve of the photoreceptor 121 according to the first sensor for being recorded, obtains the length and height of article, according to for being recorded The output valve of the photoreceptor 121 of two sensors, obtains the length and width of article, by the length of article, width and height The volume of article can be calculated.

The volume measurement device that the utility model embodiment is provided is due to the sensing provided using the utility model embodiment Device, the photoreceptor of the light-receiving component of sensor is only capable of receiving the light for carrying out self-corresponding light hole, can avoid other directions Interference of the light injected to photoreceptor.Therefore, the volume measurement device for being provided by the utility model embodiment, can avoid The measurement result caused because photoreceptor receives the light of other angles is inaccurate, makes the article volume of measurement more accurate.

It is term " " center ", " on ", D score, "left", "right", " perpendicular, it is necessary to explanation in description of the present utility model Directly ", the orientation or position relationship of the instruction such as " level ", " interior ", " outward " be based on orientation shown in the drawings or position relationship, or It is the orientation or position relationship usually put when the utility model product is used, is for only for ease of description the utility model and letter Change description, rather than indicate imply signified device or element must have specific orientation, with specific azimuth configuration and Operation, therefore it is not intended that to limitation of the present utility model.Additionally, term " first ", " second ", " the 3rd " etc. are only used for area Divide description, and it is not intended that indicating or implying relative importance.

In description of the present utility model, in addition it is also necessary to explanation, unless otherwise clearly defined and limited, term " sets Put ", " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected, or be detachably connected, Or be integrally connected；Can mechanically connect, or electrically connect；Can be joined directly together, it is also possible to by intermediary It is indirectly connected to, can is two connections of element internal.For the ordinary skill in the art, can be managed with concrete condition Solve concrete meaning of the above-mentioned term in the utility model.

Finally it should be noted that：Embodiment described above, specific embodiment only of the present utility model is used to illustrate this The technical scheme of utility model, rather than its limitations, protection domain of the present utility model is not limited thereto, although with reference to foregoing Embodiment has been described in detail to the utility model, it will be understood by those within the art that：It is any to be familiar with this skill In the technical scope that the utility model is disclosed, it still can be to the skill described in previous embodiment for the technical staff in art field Art scheme is modified or can readily occur in change, or carries out equivalent to which part technical characteristic；And these modifications, Change is replaced, and does not make the spirit and model of essence disengaging the utility model embodiment technical scheme of appropriate technical solution Enclose.Should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model described should be wanted with right The protection domain asked is defined.
