Specific embodiment
The present invention is illustrated with reference to the accompanying drawing, as shown, the present invention includes rack, the both ends of rack are respectively set
Discharge end 100 and feed end 200, feed end is corresponding with the material batch feeding end of pawl throwing mechanism, and discharge end is grabbed with material grasping robot
Hand is corresponding；
Feed inlet is arranged in the feed end, and lifting cylinder 4, the piston end and liftout of lifting cylinder is arranged in the lower section of feed inlet
Cylinder positioning plate 10 is fixed；
Discharge port is arranged in the discharge end, and lifting cylinder 4, the piston end and liftout of lifting cylinder is arranged in the lower section of discharge port
Cylinder positioning plate 10 is fixed；
Feeding web 7 is also set up between feed end and discharge end, the feeding web is driven by conveyor motor 9, from
Feed end is mobile to discharge end；
To prevent location conflicts, the feeding web 7 is that two parallel conveyer belts are driven by same conveying roller group, into
Expect the gap setting material ejection cylinder positioning plate 10 between conveyer belt.
Tray for work pieces 3 is set above material ejection cylinder positioning plate 10, and setting positioning pin 11 is used to fix workpiece on tray for work pieces 3
8；The positioning groove 31 of at least three semicircle ball-type is set on tray for work pieces 3, for example can be set 4 or 5；
Workpiece positioning plate is arranged in the top of discharge port, and the intermediate through-hole that is arranged of workpiece positioning plate is so that workpiece passes through, workpiece
The locating piece 14 that at least three spherical shape is arranged in the lower section of positioning plate is corresponding with the positioning groove 31 of 3 semicircle ball-types, such as positions
Groove is 4 or 5, then correspondingly, locating piece is also provided with respective numbers；The locating piece 14 is fixed on connecting rod 141, connecting rod
141 are fixed after the through-hole of workpiece positioning plate 1 by nut 15,141 housing of connecting rod between locating piece 14 and workpiece positioning plate 1
If buffer spring 13；
The discharge port also sets up pusher cylinder and hugs plate 2, and the pusher cylinder hugs plate 2 and the piston end of pusher cylinder 5 connects
It connects；It is corresponding and be located at tray for work pieces that pusher cylinder hugs the height when height of plate 2 and tray for work pieces 3 are jacked to discharge state
Raceway 6 is set between the top of side, discharge port and feed inlet, and the raceway is by the rotatable cylindrical roller that is parallel to each other
Composition, the tray for work pieces after discharging hug plate by pusher cylinder and push feed end to from discharge end, and the mode of promotion is subsequent workpiece
The tray for work pieces of pallet promotion front.The top of the material ejection cylinder positioning plate 10 is respectively arranged below phase with tray for work pieces 3
Matched tongue and groove 101 is to guarantee to position.Sensor is set in the tongue and groove, and the sensor transmits a signal in control
The heart.
Supporting piece gasket 12 is set on tray for work pieces, and the supporting piece gasket is sleeved on the lower end of positioning pin 11.
To guarantee to automatically control, multiple displacement sensors are arranged in the discharge end and feed end, monitor tray for work pieces in real time
Position and be transmitted to control centre.
The invention has the characteristics that；
1. being positioned with the mode of boss pit between tray for work pieces and the positioning disk of lifting cylinder, the bumps
Setting sensor occurs in slot with the phenomenon for preventing workpiece sensing inaccurate less than signal and positioning, this ensure that in the material path of lower section
It is bound to be transported in front of feeder as long as having tray for work pieces and waits feeding.After front workpiece is crawled by robots away,
A signal can be received at this time, and the lifting cylinder in front rises to the position of workpiece positioning plate, and waiting grabs next time.In fact
The mode of movement of this feeder not only ensure that the quantity for being put into material, but also workpiece can be made accurately to be positioned, direct to contract
The short length of material path, indirectly saves the occupied space of lathe.
2. positioning this problem for workpiece, multiple semi-round ball pits are processed on tray for work pieces, and in material front
Multiple locating pieces are installed in corresponding position on workpiece positioning plate, avoid tray for work pieces position not when lifting cylinder rises in this way
The phenomenon that accurately (causing positioning inaccurate).Its principle is exactly to become when lifting cylinder drives tray for work pieces to have small position when rising
Dynamic, such result has directly influenced the positioning of workpiece, affects indirectly the crawl to robot, the positioning in upper end
Multiple spherical locating pieces are put on plate, it is smooth to process multiple size surfaces with matching for opposite position on the pallet of lower section
Very high positioning groove is spent, the tray for work pieces of position vibration can be allowed to return to correct positioning using positioning groove and locating piece
Position, locating piece can rise when tray for work pieces rises and touches, but in lifting cylinder decline, locating piece meeting
It being popped into position using buffer spring and gravity, buffer spring not only contributes to that tray for work pieces is allowed to navigate to correct position,
Can also reduce causes positioning inaccurate due to long-term hard contact causes the anchor point of tray for work pieces and workpiece positioning plate to damage.Another
Also there is the boss device filled on positioning groove and head part cylinder positioning plate to match below one side tray for work pieces, in this way into one
The accuracy for increasing tray for work pieces positioning of step
3. feeder upper end idler wheel uses unpowered transmission, not only structure is simple but also can play the role of required.It is led
Wanting principle is: there are 9 tray for work pieces to be just covered with raceway on raceway, material front lifting cylinder rises, robot crawl walk with
Afterwards, it is hugged on the tray for work pieces to raceway to make the return trip empty using pusher cylinder, the tray for work pieces to be captured containing workpiece such as lower section is connected to
One signal is jacked to the position location of workpiece positioning plate to wait and be grabbed next time by lifting cylinder, and the last one pallet at this time
Also it has been pulled to upper discharge position (one pushes away a ground and advances), has expected that pawl carries out feeding at this time, one can be connected to after feeding is complete and allowed
Tray for work pieces, is transmitted in front of material path by conveyer belt and waits rising signals, circuited sequentially by the signal of lifting cylinder decline.
4. raceway both ends are equipped with the nylon anti collision plate 20 worked as a buffer, the nylon anti collision plate is along the length two sides of raceway
Tray for work pieces is clipped in the middle by setting, and the width between nylon anti collision plate is slightly larger than the width 1-2mm of tray for work pieces, so not only
Colliding with for pallet is efficiently avoided, its service life is increased, it is ensured that tray for work pieces is accurately positioned at feed end.
