In order to solve the problems, the invention adopts the following technical scheme:
the utility model provides a stoving transfer device, including outside explosion vent, inboard explosion vent and explosion-proof partition wall, outside explosion vent and inboard explosion vent are all installed on the explosion-proof partition wall, be equipped with between outside explosion vent and the inboard explosion vent and put the thing platform, one side of putting the thing platform is fixed with first cavity and second cavity, the baffle has been inlayed between first cavity and the second cavity, the passageway of sending air has been seted up to the inside of baffle, one side of baffle is fixed with the spring, but the inside of first cavity is equipped with cyclic reciprocating motion's piston, the one end and the spring fixed connection that the piston is close to the baffle, the check valve has been seted up to one side of piston, one side that the piston is close to inboard explosion vent is fixedly connected with connecting rod, run through in the second cavity and be equipped with the bleeder, the inside of second cavity is fixed with air pressure sensor, the inside fixedly connected with controller and the inductor of outside explosion vent, one side embedding of outside explosion vent has the spout, fixed mounting has power motor on the explosion-proof partition wall, fixed motor and the inside spout position corresponds with outside explosion vent, the outside explosion vent and explosion-proof partition wall's outside is for transporting machine and transportation robot can freely move in the explosion-proof corridor.
The working principle of the scheme is as follows:
when the baking is finished between the baking chambers, the inner explosion-proof door is opened, the connecting rod and the piston are not extruded by the inner explosion-proof door and spring up under the action of the spring, meanwhile, the air pressure reduced by the space of the first chamber is increased after the piston springs up to the first chamber through the one-way valve, the air pressure in the first chamber and the air pressure in the second chamber are always kept in a balanced state, then the medicine tray is placed on the object placing table through the manipulator, then the inner explosion-proof door is closed, at the moment, the connecting rod is extruded by the inner explosion-proof door to push the piston to slowly charge air into the second chamber, after the inner explosion-proof door is completely closed, the air in the first chamber is still continuously charged into the second chamber until the air pressure in the second chamber exceeds the pressure set by the system, the air pressure sensor is triggered to send an air pressure overload signal to the controller, the controller immediately makes judgment of opening the outer explosion-proof door through the signal control mode, the power motor is driven to work, the outer explosion-proof door is opened through the power motor, and when the outer explosion-proof door is opened, the air is not automatically released after the outer explosion-proof door is opened, and therefore the air in the second chamber is released.
After the outside explosion vent is opened completely, the controller sends a signal to the transfer robot to transfer the medicine tray, the sensor senses that the transfer robot leaves and then controls the driving motor to close the outside explosion vent, after the outside explosion vent is closed completely, the controller can send an openable signal to the inside explosion vent, at least one of the two explosion vents is closed in the transfer process of the medicine tray, and safety is improved.
The beneficial effect that this scheme produced is:
when the inner side explosion-proof door is opened, the connecting rod and the piston are not sprung up under the action of the spring after being extruded by the inner side explosion-proof door, at the moment, the space of the first chamber is increased, the air pressure of the second chamber flows towards the first chamber, so that the second chamber forms negative pressure, in order to compensate the partial air pressure change, the one-way valve is arranged on the piston, so that the piston is filled with air into the first chamber in the bouncing process, the air pressure difference changed by the space increase is compensated, the air pressure in the first chamber and the second chamber is always kept in an equilibrium state, the negative pressure state caused by the air pressure difference is avoided, the outer side explosion-proof door cannot be controlled to be opened when the inner side explosion-proof door is closed, and secondly, the air supply channel is arranged on the partition plate between the first chamber and the second chamber, and the diameter ratio of the air supply channel and the first chamber and the second chamber is controlled to be 0.5-1:20, after the inner explosion door is completely closed, the air flow of the air supply channel is smaller, so that the air of the first chamber cannot enter the second chamber quickly, namely, after the explosion door is closed, the pressure in the first chamber rises quickly, and the pressure in the second chamber cannot rise quickly due to the limitation of the air flow of the air supply channel, namely, the air pressure in the second chamber can be kept at a time interval of 40-60 seconds when the air is supplied into the second chamber by the first chamber and exceeds the air pressure set by the system, then an air pressure overload signal is sent, and the controller judges that the driving power motor opens the outer explosion door, so that the inner explosion door is in a closed state when the outer explosion door is opened, and the safety is greatly improved.
Further, the end of the air release valve is embedded with a valve rod. The valve rod is contacted with the outer explosion-proof door and is extruded by the outer explosion-proof door to open or close the air release valve, so that the second chamber is ensured to be always in a normal pressure state.
Further, a rotating shaft is embedded in the power motor. The pulley is installed to the tip of pivot, through embedding the pulley in the spout of outside explosion vent, and when the controller control motor work, the pivot rotates, drives outside explosion vent to one side slip to open outside explosion vent.
Further, rubber pads are fixedly arranged on the explosion-proof partition walls of the outer explosion-proof door and the inner explosion-proof door. The rubber pad can protect the inner and outer explosion-proof doors from being damaged due to collision with the explosion-proof partition wall when the inner and outer explosion-proof doors are closed, the service life of the explosion-proof doors is prolonged, the friction force between the inner and outer explosion-proof doors and the explosion-proof partition wall when the explosion-proof doors are closed can be reduced, and safety production is guaranteed.
Further, the first chamber and the second chamber are made of stainless steel, and the inner diameter of the chamber is 20cm. The first chamber and the second chamber realize the linkage of the two explosion vents by utilizing the air pressure change, so that the production automation degree and the production efficiency are improved.
Further, the material of the partition plate is stainless steel. The air between the first chamber and the second chamber is effectively isolated through the partition plate, and the constant pressure in the chamber is effectively ensured.
Further, the piston is made of aluminum alloy. The piston is in reciprocating circulation motion in the first cavity, so that gas can be filled into the second cavity when the inner explosion door is closed every time, and the air pressure sensor control controller is triggered to drive the power motor to work, so that the outer explosion door is opened, and further linkage is realized between the two explosion doors, namely, the outer explosion door is opened when the inner explosion door is closed.
Further, the middle part of the inner side wall of the outer explosion door is embedded with a gas leakage groove. When the outer explosion-proof door slides rightwards to be opened to a certain position, the air release valve penetrating through the second chamber can enter the air release groove, and at the moment, the air release valve is opened to release air in the second chamber, so that the air is prevented from remaining in the second chamber, and the linkage of the outer explosion-proof door and the inner explosion-proof door is prevented from being influenced.
