However, when using such a non-contact type detection device to detect and count products on a line, it is necessary to have a requirement for the cross section of the products, namely: the product is required to have a large reflective surface, and if the reflective surface of the product is small, the conveyor belt is usually transported at a high speed, in which case accurate counting of the product on the line is not possible with a non-contact detection device.

As shown in fig. 1 to 3, the squirrel-cage magnetic contact type rotary dial counting device provided by the invention comprises afixed mounting shaft 1, a squirrel-cage shell 2, adial 3 and a magnetic electric contact piece 4. The squirrel-cage shell 2 is provided with agrid 21, the squirrel-cage shell 2 is sleeved on thefixed installation shaft 1 and can rotate around thefixed installation shaft 1, thefixed installation shaft 1 is fixed on one side of an external transmission device through a bearing, thedialing code 3 is perpendicular to the axial direction of thefixed installation shaft 1, thedialing code 3 is located above the transmission device and is consistent with the incoming material direction of an object to be counted, which is transmitted on the transmission device, and therefore the object to be counted, which is located above the transmission device, can push thedialing code 3 to rotate. Thedial 3 is arranged on the outer side wall of the squirrel-cage shell 2, when an object to be counted passes through, thedial 3 is touched to enable thedial 3 to rotate, and the rotatingdial 3 can drive the squirrel-cage shell 2 to rotate.
In one example of the present invention, thesquirrel cage casing 2 is a hollow cylindrical structure, and 3 dialing codes with plate-shaped or cylindrical structures are uniformly arranged on the outer side wall of the cylindrical structure.
In addition, a magnetic electric contact sheet 4 is fixedly arranged on the fixedmounting shaft 1, an object to be counted touches thedialing code 3 in the transmission process (namely, the dialing code is touched by the object to be counted in the transmission process), thedialing code 3 drives the squirrel-cage shell 2 to rotate, and as the squirrel-cage shell 2 is provided with agrid 21, when the squirrel-cage shell 2 rotates, the rotating squirrel-cage shell and the magnetic electric contact sheet generate electromagnetic induction, a detection signal for the passing of the object to be counted is generated through the electromagnetic induction generated by the magnetic electric contact sheet and the rotating squirrel-cage shell, and the object to be counted can be counted according to the detection signal.
In particular, an external closed circuit is provided, to which the magnetic electrical contact strip is connected, by means of which a detection signal is generated for the passage of the object to be counted. Wherein, the primary connection and disconnection of the closed loop is regarded as a detection signal of the passing of an object to be counted generated by electromagnetic induction generated by the magnetic electric contact sheet and the squirrel cage shell. Specifically, when the grid of the squirrel cage enclosure is rotated to a position corresponding to the magnetic electrical contact pads, the magnetic electrical contact pads generate an electrical signal that turns on the closed circuit; when the grid of the squirrel cage housing is rotated to a position that is interleaved with the magnetic electrical contact pads, the magnetic electrical contact pads generate an electrical signal that opens the closed circuit.

In addition, since the object to be counted touches the dialing code during the transmission process, namely: the object to be counted contacts with the dialing code, and the transmission speed of the transmission device is generally higher, so that the object to be counted is damaged to some extent due to the impact of inertia when contacting with the dialing code. Therefore, in the squirrel-cage magnetic contact type 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.

However, in order to easily and accurately count objects to be counted with small edge area, when the counting device provided by the invention is installed, the axial direction of thefixed installation shaft 1 is perpendicular to the conveying direction of the objects to be counted, so that the objects to be counted, of which the dialing codes are conveyed, can be touched, thereby driving the closed shell to rotate and further improving the counting precision.
The following describes the working process of the squirrel-cage magnetic contact type rotary dial counting device provided by the invention by taking the transportation of angle steel on a conveying device as an example.
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 squirrel-cage shell is driven to rotate, and as the squirrel-cage shell is provided with grids, the magnetic electric contact pieces can generate detection signals with angle steel passing through by utilizing the grids of the squirrel-cage shell. In addition, the squirrel-cage magnetic contact type 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 squirrel-cage magnetic contact type 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 is separated from the signal conversion transmission, the reliability of detection is improved, and the device is particularly suitable for counting objects with extremely small edge areas.
