For the purpose of describing in detail the enclosed-housing photoelectric rotary dial counting device provided by the invention, fig. 1 shows a horizontal section structure of the enclosed-housing photoelectric rotary dial counting device according to an embodiment of the invention, fig. 2 shows a detection piece plane unfolding structure of the enclosed-housing photoelectric rotary dial counting device according to an embodiment of the invention, and fig. 3 shows an axial section structure of the enclosed-housing photoelectric rotary dial counting device according to an embodiment of the invention.
As shown in fig. 1 to 3, the enclosed-shell type photoelectric rotary dial counting device provided by the invention comprises a fixed mounting shaft 1, an enclosed shell 2, a dial 3 and a detection piece 4. Wherein, seal shell 2 cover is established on fixed mounting axle 1 and can rotate around fixed mounting axle 1, and wherein, fixed mounting axle 1 passes through the bearing to be fixed in one side of outside transmission device, and dial 3 is mutually perpendicular with the axial of fixed mounting axle 1, and dial 3 is located transmission device's top, and the incoming material direction of waiting to count object that transmits on the transmission device is unanimous, so, is located transmission device top wait to count the object just can promote dial 3 rotation. The dial 3 is arranged on the outer side wall of the closed shell 2, and the detection piece 4 is of a protruding structure, is arranged on the inner side wall of the closed shell and corresponds to the dial 3.
It should be noted that, the correspondence here refers to how many dialing codes are provided on the outer side wall of the closed casing 2, and how many raised detection pieces are provided on the inner side wall of the closed casing correspondingly. In one example of the present invention, the closed housing 2 is a hollow cylindrical structure, and the outer side wall of the cylindrical structure is uniformly provided with 3 dialing codes of a plate shape or a cylindrical structure, and then, correspondingly, the inner side wall of the hollow cylindrical structure is also provided with 3 raised detection pieces, wherein each detection piece corresponds to one dialing code.
In addition, a photoelectric sensor 5 is fixedly arranged on the fixed mounting shaft 1, an object to be counted touches the dial 3 in the transmission process (namely, the dial is touched by the object to be counted in the transmission process), the dial 3 drives the closed shell 2 to rotate, so that a detection sheet 4 arranged in the closed shell 2 rotates along with the closed shell 2, after the detection sheet 4 rotates, the photoelectric sensor 5 and the detection sheet 4 generate photoelectric induction so as to generate a detection signal for the object to be counted to pass, and the object to be counted can be counted according to the detection signal.
Specifically, when the dial drives the closed shell 2 to rotate, the detection piece arranged in the closed shell 2 rotates along with the closed shell 2, and as the detection piece is of a convex structure, when an object to be counted passes, the convex detection piece rotates to correspond to the photoelectric sensor 5, and when the detection piece rotates to a position corresponding to the photoelectric sensor 5, the photoelectric sensor generates a corresponding optical signal and converts the optical signal into an on electrical signal by virtue of a photoelectric element in the photoelectric sensor; when the detection sheet rotates to a position staggered with the photoelectric sensor, the photoelectric sensor is restored to an initial state, and the electric signal is disconnected; therefore, the on and off of the electric signal can be regarded as a detection signal that the object to be counted passes by generated by the photoelectric sensing occurring between the photoelectric sensor and the detection piece. Wherein, one turn-on and turn-off of the electric signal is regarded as that an object to be counted passes.

In addition, since the object to be counted touches the dialing code during the transmission process, namely: the object to be counted can be contacted with the dialing code, and the transmission speed of the transmission device is generally higher, so that the dialing code is damaged to some extent due to the impact of inertia when the object to be counted is contacted with the dialing code. Therefore, in the closed shell type photoelectric rotary dial counting device provided by the invention, the dial can be made of a few low-hardness high-wear-resistance materials, for example, the dial can be made of cast iron, babbitt alloy or bronze alloy and other materials, so that the object is prevented from being damaged when the object is contacted with the dial. Namely: the dialing code can be cast iron dialing code, babbitt alloy dialing code or bronze alloy dialing code.

The counting device provided by the invention is arranged in a gap below the conveying device, and the fixed installation shaft of the counting device is vertical to the incoming material direction of the object to be counted conveyed by the conveying device, so that the dial can be triggered and rotated by angle steel in the conveying process. When the dial is rotated, the closed shell is driven to rotate, and as the protruding detection sheet structures are distributed on the inner side wall of the shell, the change of the photoelectric sensor detection signal can be caused by the detection sheet, and the change of the signal is the detection signal with angle steel passing through.
In addition, the closed shell type photoelectric rotary dial counting device provided by the invention adopts a rotary structure, so that after the last dial is touched, the shell rotates, and the next dial can be pushed to the position where the angle steel passes, so that the next angle steel can be waited for passing. Through the rotary cyclic work of dial like this, send the signal that has the angle steel to pass through to the controller to just realized the cycle count of the angle steel transported on the conveyer.
According to the closed shell type photoelectric rotary dial counting device, the approach signal detection of the edge of the object is changed into the signal detection of the dial connecting component, so that the obtained object arrival signal and the signal are converted and transmitted separately, the reliability of detection is improved, and the device is particularly suitable for counting objects with extremely small edge areas.
