The working process and principle for being fed and cutting unit 20 are as follows: in starting feed and before cutting unit, first supplying
Coiled raw material leather strap is placed on charging tray 202.The free end for pulling leather strap downwards manually makes leather strap with serpentine around each level
After positioning column 215, it is first passed down through positioning square hole 213, is then passed through the gap between clamp arm 210 and vertical plate 207, until leather strap is certainly
By gap of the end slightly below between clamp arm 210 and vertical plate 207.After starting is fed and cuts unit, firstly, the first plug-type electromagnetism
The output end of iron 209 forward extends out, and clamp arm 210 is pushed to travel forward, so that clamp arm 210 cooperates vertical plate 207 to clamp leather strap.So
Afterwards, the output end of first straight line movement cylinders 203 moves downward, so that the free end of leather strap is pulled downward on, at this point, supply disk 202
Rotation, to implement the feed of leather strap.When the free end of leather strap is pulled down to 217 position of clamper, first straight line fortune
Dynamic 203 stop motion of cylinder, then clamper 217 starts, and clamps the free end of leather strap.Later, first push-pull electromagnet 209
Output end recycling, so that clamp arm 210 leaves leather strap, then the output end of first straight line movement cylinders 203 rises.Then, starting the
The output end of two linear movement cylinders 204, second straight line movement cylinders 204 drives push rod 263 to move downward by bent over arms 227, this
When third push-pull electromagnet 276 output in the state of stretching, push rod 263 is defeated by third push-pull electromagnet 276
Outlet pushes L shape push rod 273 to travel forward.The push rod 273 to travel forward pushes the second guide rail 279 first with pitch drives face
Horizontal movement reaches the side of leather strap so that horizontal driving lever 286 be driven to protrude horizontally up.Later, control clamper 217 unclamps skin
The free end of item.When push rod 273, which is moved forward to, to be contacted with baffle 271, push rod 273, which moves forward, will drive second
Guide rail 279 travels forward, thus make stretch out horizontal driving lever 286 travel forward, as a result, using horizontal driving lever 286 by leather strap with
The state of folding pushes in the clamping part 502 of buanch unit 50.Later, clamping part 502 clamps the leather strap folded.In clamping part
After 502 clamp the leather strap of folded state, the output end of the second push-pull electromagnet 219 of control is forward extended out, and is cut under
Knife 224 is located at the underface of upper cutting knife 208.Then the output end for controlling first straight line movement cylinders 203 moves downward again, from
And the upper downward cutting knife 224 of cutting knife 208 movement is driven, edge of a knife closure cuts leather strap.
Stapling unit 30 uses sewing machine.To be fed and cut after unit 20 cuts leather strap, clamping part 502, which is clamped, to be cut
Leather strap that is coming and being in folded state, in the position for being rotated by 30 place of stapling unit of transfer portion 501.Then,
Stapling unit 30 starts, and the leather strap of folding is sutured in end, to form chape.The chape sutured is again by turning
It moves unit 50 to send to finished product input station, it may be assumed that unclamp chape after the chape for completing suture is transferred to specified station.
