b2, the piston rod A of the clamping cylinder of the clamping jaw 43 extends out to drive the pressing sheet 435 to move towards the supporting sheet 433, so that all the tobacco stems in the feeding unit at the lowest layer and the penultimate spacer 2 pressed on the tobacco stems are clamped between the supporting sheet 433 of the clamping jaw 43 and the pressing sheet 435;
b3, the electromagnet B of the clamping jaw 43 is activated, so that the penultimate spacer 2 is firmly attached to the pressing piece 435 of the clamping jaw 43.
c, shaking and loosening the feeding unit at the lowest layer:
c1, the mechanical arm 42 of the multi-axis robot moves to drive the clamping jaw 43 to move upwards, and further drive the lowest layer feeding unit and the penultimate layer spacer 2 clamped by the clamping jaw 43 to move upwards, so that interference with the bottom surface of the material frame is avoided during subsequent shaking operation;
c2, the mechanical arm 42 of the multi-axis robot acts to drive the clamping jaw 43 to swing back and forth in the transverse vertical plane, so that the tobacco leaves to be baked in the feeding unit at the lowest layer clamped by the clamping jaw 43 are shaken and loosened;
c3, starting the pitching cylinder 438 of the clamping jaw 43, and driving the clamping jaw 43 to swing back and forth in the vertical longitudinal plane through the reciprocating extension of the piston rod B of the pitching cylinder 438, so that the tobacco leaves to be cured in the feeding unit at the lowest layer clamped by the clamping jaw 43 further shake and loosen.
d, unloading the clamped lowest layer feeding unit onto a baking equipment conveyor belt:
d1, the mechanical arm 42 of the multi-axis robot acts to drive the clamping jaw 43 to move above the conveyor belt of the baking equipment;
d2, the piston rod A of the clamping cylinder of the clamping jaw 43 retracts to drive the pressing sheet 435 to move away from the supporting sheet 433, the tobacco stems of the feeding units at the lowest layer are loosened, and the feeding units at the lowest layer fall down and are spread on the continuously running conveyor belt.
e, unloading the penultimate spacer:
e1, the mechanical arm 42 of the multi-axis robot acts to drive the clamping jaw 43 to move to the preset unloading spacer 2 area;
e2, de-energizing the electromagnet B of the clamping jaw 43, unloading the penultimate separator 2 in the preset unloading separator 2 area;
in this step, the horizontal vertical plane is a vertical plane parallel to the width direction of the material frame, the longitudinal vertical plane is a vertical plane parallel to the length direction of the material frame, the width direction of the material frame 1 is a direction parallel to the filling port 11 of the material frame 1 (see the direction of the dotted line m in fig. 4), and the length direction of the material frame 1 is a direction perpendicular to the filling port 11 of the material frame 1 (see the direction of the dotted line n in fig. 4).
In the step, the steps of c2 and c3 are not in sequence.
Claims (3)
1. Tobacco redrying material loading process material loading unit separation external member, characterized by: comprises a material frame, a spacer and a spacer control device;
one side wall or two opposite side walls of the material frame are opened to form a filling opening, and two sides of the filling opening are provided with spacer piece placing grooves which are opposite in position and are vertically arranged;
two ends of the spacer are horizontally placed in the spacer placing grooves on two sides of the material frame filling opening;
spacer control means are associated with the spacer to control the spacer to be raised or lowered along the spacer seating groove.
2. The tobacco redrying feeding procedure feeding unit separation kit of claim 1, characterized in that: the spacer control device comprises a lead screw, a lead screw seat, a nut, a motor A, a motor B, a connecting rod, an electromagnet A, an upper fixed claw and a lower fixed claw; the screw rod is movably arranged on the screw rod seat and is vertically arranged; the nut is screwed with the screw rod; the motor A is arranged on the screw rod seat and is associated with the screw rod so as to drive the screw rod to rotate; the motor B is fixedly arranged on the nut, and a crankshaft of the motor B vertically extends out; the front end of the connecting rod is fixedly arranged on a crankshaft of the motor B; the electromagnet A is fixedly connected to the rear end of the connecting rod; the upper fixing claw and the lower fixing claw are fixedly connected to the upper end and the lower end of the screw rod seat respectively; the two spacer control devices are respectively arranged at two sides of the material frame filling opening, and each spacer control device is clamped and fixed with the upper edge and the lower edge of the material frame through an upper fixing claw and a lower fixing claw; a machine shaft of a motor B of the spacer control device rotates to drive the connecting rod to horizontally rotate, so that the electromagnet A is driven to be switched between the suction position and the avoidance position, the electromagnet A in the suction position is opposite to the spacer, and the electromagnet A in the avoidance position avoids a path along which the spacer is lifted along the spacer mounting groove.
3. The tobacco redrying feeding procedure feeding unit separation kit of claim 2, characterized in that: the lower end of the screw rod seat is fixedly connected with a support leg.
