Formula conveyer includes rack 5, and the multiple conveying rollers 6 being provided with side by side are rotated in rack 5, and the setting of 7 device of stop baffle is accumulating
In the rack 5 of roller bed type conveyer, 7 device of stop baffle includes that vertical stop baffle 7 and driving stop baffle 7 move
Four-bar mechanism, one layer of buffer stopper 8 is equipped on rear side of 7 top of stop baffle.Four-bar mechanism includes two lower links 9, two
Upper connecting rod 10, upper shaft 11, lower rotary shaft 12, upper shaft 11, lower rotary shaft 12 are respectively and fixedly installed in rack 5 and in parallel up and down
Setting, the front end of two lower links 9 are respectively hinged on lower rotary shaft 12, and the rear end of two lower links 9 is respectively hinged at stop catch
The front end of the lower part of plate 7, two upper connecting rods 10 is respectively hinged in shaft 11, and the rear end of two upper connecting rods 10 is respectively hinged at
The middle part of stop baffle 7 drives two upper connecting rods 10 to be rotated around upper shaft 11 by driving mechanism, connects under two to drive
Bar 9 is rotated synchronously around lower rotary shaft 12, and then arcuately track is lifted drive stop baffle 7.
Wherein, driving mechanism is cylinder 13, and the cylinder body lower end of cylinder 13 is hinged in rack 5 and is located at two lower links 9
Between, the front end of two upper connecting rods 10 is linked together by a drive shaft 18, and drive shaft 18 is parallel with upper shaft 11, gas
The piston rod of cylinder 13 is stretched out and is rotatablely connected with drive shaft 18 upwards, and the piston rod upper end of cylinder 13 passes through a connecting bushing
14 is hinged with the rotation of drive shaft 18, flexible to drive two upper connecting rods 10 around upper shaft 11 by the piston rod of cylinder 13
Rotation.Photoelectric tube 15 is additionally provided in rack 5, photoelectric tube 15 is located at 6 side of conveying roller, by the feedback signal of photoelectric tube 15 come
Control the rotation of conveying roller 6 and the keying for stopping and controlling driving mechanism.
Be additionally provided in rack 5 the upper limit bar 16 limited for the upper limit position to upper connecting rod 10, for pair
The lower limit bar 17 that the lower limit position of lower link 9 is limited, when upper connecting rod 10 is contacted with upper limit bar 16, upper connecting rod 10
It is in horizontality with lower link 9, and the upper end of stop baffle 7 is stretched out on conveying roller 6, lower link 9 and lower limit bar 17
