In order to avoid the overhigh air pressure, a pressure reducing valve 4-6 is fixed on the stand 4-2.
The working principle is as follows:
1) feeding: the workpieces arranged on the slide 1-1 slide to the left end of the conveying frame 1-12, the workpieces move to the position of a signal device along a conveying path formed by the guide rods 1-7 and the round belts 1-10 under the drive of the round belts 1-10, the sensor 1-3 is triggered through the deflector rod and the dial wheel 1-4, and the controller (not shown in the figure) instructs the separation cylinder 1-9 to move and drives one stop pin 1-13 to extend and the other stop pin 1-13 to retract through the mounting frame 1-5. The front workpiece is allowed to move further forward (to the right in fig. 1 and 2) by the retracting stop pin 1-13, while the rear workpiece is blocked from movement by the extending stop pin 1-13. The piston rods of the separating cylinders 1-9 continuously extend and retract, so that the workpieces can be separated according to the beat.
2) Material distribution: when moving to the rightmost end of the conveying frame 1-12, the workpiece falls into a V-shaped positioning block 2-6 of a first group of material receiving devices, and a first proximity switch 2-5 on the first group of material receiving devices instructs a piston rod of a first longitudinal cylinder 2-1 to extend out through the controller and sends the workpiece to the lower part of a first group of carrying devices (positioned on the front side or the back side of the frame 3-8); in the process, the second group of material receiving devices of the material distributing unit 2 moves to the conveying frames 1-12 along with the material distributing unit and receives the next workpiece, and a first proximity switch 2-5 on the second group of material receiving devices sends the workpiece to the lower part of the second group of carrying devices (positioned on the back or front of the machine frame 3-8) by instructing a piston rod of the first longitudinal cylinder 2-1 to retract through a controller; meanwhile, the first group of receiving devices return to the initial position to be ready for receiving the subsequent workpieces.
3) Carrying: because the double-station carrying unit 3 is composed of the carrying devices which have the same structure and are respectively positioned on the front and the back of the machine frame 3-8, the working process of any one group of carrying devices is only needed to be decomposed.
A third proximity switch 3-10 on the carrying device instructs a piston rod of a first transverse cylinder 3-9 to retract through a controller, and drives two first lifting cylinders 3-1 fixed on the third proximity switch to move leftwards to the upper part of a workpiece through a first transverse sliding plate 3-5, the piston rods of the two first lifting cylinders 3-1 extend out and respectively drive respective suckers 3-3 to move downwards through corresponding first vertical sliding frames 3-4 and suck the workpiece (the left sucker 3-3 sucks the workpiece on the V-shaped positioning block 2-6, the right sucker 3-3 sucks the workpiece in an airtight positioning seat 4-11), and then the piston rods of the two first lifting cylinders 3-1 retract to lift the workpiece; the controller instructs the piston rods of the first transverse cylinders 3-9 to extend to push the first transverse sliding plates 3-5 to move rightwards, the piston rods of the two first lifting cylinders 3-1 extend to drive the workpiece to descend through the corresponding suckers 3-3 respectively, and the workpiece is released (the left sucker 3-3 releases the workpiece in the sealing and positioning seat 4-11, and the right sucker 3-3 releases the workpiece in the slide way 5-2 of the unloading unit 5). After the workpieces are conveyed, the conveying device returns to the initial position, and the subsequent workpieces are conveyed in the northest direction.
4) And (3) air tightness detection: after the air valve is placed in the airtight positioning seat 4-11 by the carrying device, the controller instructs the piston rod of the second longitudinal air cylinder 4-9 to extend out, and the piston rod pushes the second longitudinal sliding plate 4-4 to move to the position below the airtight pressure head 4-12; the fourth proximity switch 4-7 instructs a piston rod of the second lifting cylinder 4-14 to extend through the controller and drives the airtight pressure head 4-12 to move downwards through the second vertical sliding frame 4-13; pressure gas enters a sealed cavity formed by the airtight positioning seat 4-11 and the airtight pressure head 4-12 through the electromagnetic valve 4-1, and whether the airtight performance of the conical surface of the workpiece is qualified or not can be judged according to the pressure change of the sealed cavity after pressure maintaining for a certain time. After the air tightness detection is finished, the second lifting cylinder 4-14 drives the air tightness pressure head 4-12 to ascend, the piston rod of the second longitudinal cylinder 4-9 retracts, the second longitudinal sliding plate 4-4 is pulled to retract to the initial position, and the carrying device is waited to unload materials.
