[0025] Embodiment 2
[0026] A control circuit of a case cigarette sorting and buffering device is used to control the case cigarette sorting and buffering device in the above Embodiment 1.
[0027] As Figure 4 shown, the control circuit includes a first photoelectric tube B1, a second photoelectric tube B2, a third photoelectric tube B3, a proximity switch SQ, a first branch, a second branch, a third branch, a fourth branch, a fifth branch, and a sixth branch that are connected across the positive and negative poles of the power supply;
[0028] The first branch includes the normally open contact K11 of the first relay and the monostable solenoid valve D connected in series; the second branch includes the normally open contact K31 of the third relay and the coil KM1 of the first AC contactor connected in series; the third branch includes a parallel branch and the coil KM2 of the second AC contactor connected in series. One branch of the parallel branch includes the normally open contact K21 of the second relay and the contact SQ1 of the proximity switch connected in series, and the other branch includes the normally open contact KM21 of the second AC contactor and the normally closed contact B31 of the third phototube connected in series; the fourth branch includes the normally open contact B11 of the first phototube, the normally closed contact B21 of the second phototube and the coil K1 of the first relay connected in series; the fifth branch includes the normally open contact B22 of the second phototube, the second normally closed contact B32 of the third phototube and the coil K2 of the second relay connected in series; the sixth branch includes the second normally open contact K22 of the second relay and the coil K3 of the third time-delay relay connected in series, and the second normally open contact K12 of the first relay is connected in parallel with the normally open contact K22 of the second relay; the first drive motor M1 is connected in series with the normally open contact KM11 of the first AC contactor, the second drive motor M2 is connected in series with the second normally open contact KM22 of the second AC contactor, and the electric push rod is connected in series with the monostable solenoid valve D.
[0029] The control process of this control circuit is as follows:
[0030] Into the buffer: When the first phototube B1 detects that there is a carton of cigarettes passing by, the normally open contact B11 of the first phototube closes, the coil K1 of the first relay is energized, the normally open contact K11 of the first relay closes, the monostable solenoid valve D is energized, and the electric push rod drives the baffle to descend. At the same time, the second normally open contact K12 of the first relay closes, the coil K3 of the third time-delay relay is energized, the normally open contact K31 of the third time-delay relay closes, the coil KM1 of the first AC contactor is energized, the normally open contact KM11 of the first AC contactor closes, and the first motor M1 drives the conveying mechanism to convey the carton of cigarettes in the downstream direction.
[0031] When the cigarette case is conveyed to the upstream side of the flipping mechanism, the normally open contact B11 of the first photoelectric tube disconnects, the coil K1 of the first relay loses power, the first normally open contact K11 of the first relay disconnects, the monostable solenoid valve D loses power, and the electric push rod drives the baffle to rise to block the subsequent cigarette cases. At the same time, the normally open contact B22 of the second photoelectric tube closes, the coil K2 of the second relay is powered on, the first normally open contact K21 of the second relay closes, the contact SQ1 of the proximity switch is initially in the closed state, the coil KM2 of the second AC contactor is powered on, the first normally open contact KM21 and the second normally open contact KM22 of the second AC contactor close, the second motor M2 drives the transmission shaft to rotate, and the cigarette case flips under the action of the flipping piece. At this time, the proximity switch is no longer aligned with the protrusion, and the contact SQ1 of the proximity switch disconnects. However, since the first normally open contact KM21 of the second AC contactor is in the closed state at this time, the coil KM2 of the second AC contactor remains powered on. When the flipping mechanism rotates 90°, the cigarette case is located on the downstream side of the flipping mechanism. At this time, the first normally closed contact B31 and the second normally closed contact B32 of the third photoelectric tube disconnect, the coil K2 of the second relay loses power, and the first normally open contact K21 and the second normally open contact K22 of the second relay disconnect. Since both B31 and K21 are disconnected, the coil KM2 of the second AC contactor loses power, the first normally open contact KM21 and the second normally open contact KM22 of the second AC contactor disconnect, the second motor M2 stops, and the rotating mechanism stops flipping. The cigarette case just flips 90° under the action of the flipping mechanism. At this time, since the proximity switch is aligned with the protrusion again, the contact SQ1 of the proximity switch closes again, preparing for the next flip. After the rotating mechanism stops flipping, the coil K3 of the third time-delay relay remains powered on for 10 s, and the conveying mechanism keeps running for 10 s (the normally open contact K31 of the third time-delay relay delays to turn off after the coil K3 is powered off), ensuring that the cigarette case is conveyed out and creating space for the subsequent cigarette cases. Each time the flipping mechanism at the inlet end operates, the conveying mechanism runs synchronously. In this way, the subsequent cigarette cases will gradually compress the gaps between the cigarette cases, and finally be closely arranged at the position of the outlet baffle in sequence, greatly reducing the occupied space of the cigarette cases and increasing the buffering capacity of the buffering device.
[0032] The control process for discharging from the buffer is the same as that for entering the buffer, so it will not be elaborated here.
[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
