The specific embodiment

As can be seen from Figure 1, when roller set 12 was driven by the actuating device of forming such as motor and speed reduction gearing 11, feeding roller set 12 was rotated according to identical direction, and workpiece can be sent to the direction that should move.Be positioned at a kind of photoelectric switch of charging detecting sensor 13 employings that feeding roller set 12 terminals are provided with regularly, such as closed type photoelectric switch E3F-DS10Y2.Sensor 13 faces the workpiece of being delivered to processing district or treatment region 18 by the feeding roller set forward, and when workpiece was sent into processing district or treatment region 18 forward, sensor 13 can sense workpiece and exist.At this moment, the transistor in sensor 13 photoelectric switchs ends, and does not have signal to send.When workpiece fully by roller set 12, and the surveyed area by sensor 13 all enters after the processing district 18 subsequently, has not had workpiece to exist in sensor 13 fronts.Sensor 13 sends detection signal and gives relay K A1, and KA1 makes material loading drum drive 14 (such as being a kind of infinite speed variation motor) energized, and feed roller 15 rotates in the driving.

Last feed roller 15 is settled near roller set 12, and the axis of cylinder 15 is parallel with roller set 12.Along cylinder 15 axial edge one side the hook-shaped annex or the groove 16 that can only hold a workpiece arranged, when cylinder 15 did not rotate, hook or groove 16 were positioned at and roller set 12 axisymmetric sides, and held in the workpiece to be processed that order arrives one in advance.When cylinder 15 rotated, a workpiece that holds in advance can be driven by cylinder 15 and rotate towards roller set 12 1 sides.Can be in roller set 12 1 side settings such as a kind of material-receiving device 23.The workpiece that material-receiving device 23 can have multiple design to admit cylinder 15 bands to come, such as resembling as shown in Figure 4, along cylinder 15 axially, near the cylindrical of cylinder 15 a plurality of arcs are set according to Workpiece length, the upper end of all arcs is near cylinder 15 outer gardens and exceed the edge line of cylinder 15 in roller set 12 1 sides, the slit that forms between the upper end of arc and the cylinder 15 is unlikely to leak down workpiece, and the end of a plurality of arcs is on the straight line that is parallel to cylinder 15 axis.The arc lower end of arc is guided workpiece on the roller set 12 near roller set 12.When an edge at the hook that holds workpiece of cylinder 15 or groove place turns over 90 °, last feed roller 15 is rotated further again, workpiece will drop on the material-receiving device 23, and is arrived on the feeding roller set 12 by the arch section guiding of a plurality of material-receiving devices 23, and is sent to forward by the feeding roller set.Make workpiece can directly not drop on the feeding roller set 12, the unlikely damage that causes workpiece or feeding roller set 12 from cylinder 15.

When last feed roller 15 forwarded reference position to, a new workpiece can enter again in the hook-shaped annex or groove 16 of feed roller, waited for material loading next time.

Last feed roller detector 17 places regularly and leaves about 5-8 centimetre at feed roller 15 axial ends, and the test surface of detector 17 is facing to the edge of cylinder 15.One end of cylinder 15 feed roller detector 17 on it faces toward, have vertically one face detector 17, length is 4-6 centimetre projection 22.Last feed roller detector 17 is a kind of inductance approach switches, such as open in usual near switch LJ18A3-8-J/EZ.When cylinder 15 does not rotate, will face detector 17 because of projection 22, produce electric signal near the transistor turns in the switch.And after cylinder 15 rotated, the projection 22 of cylinder 15 1 ends was rotated with cylinder 15, just no longer faced detector 17, and the transistor in the detector 17 does not produce electric signal.

Specifically, when last feed roller 15 did not rotate, detector 17 detected projection 22, and detector 17 outputs signal to relay K A2, this relay K A2 makes the relay K A1 disconnection with its interlock, does not have driving power and is added on the material loading drum drive 14.And as mentioned above, after workpiece entered processing district 18 fully, when not had workpiece to exist before sensor 13, sensor 13 sent detection signal, by relay K A1 feed roller 15 was rotated.When cylinder 15 rotations were got back to original position in one week, detector 17 detects projection 22 again, detector 17 outputs signal to relay K A2, this relay K A2 makes the relay K A1 disconnection with its interlock, power failure to material loading drum drive 14, cylinder 15 stops operating, and waits for that feed next time rotates indication.

The workpiece to be processed if the hook of cylinder 15 or groove 16 fail normally to receive, charging detecting sensor 13 can not detect the existence of workpiece, signal output is just arranged always, KA1 just is driven always, and cylinder 15 will rotate always, even cylinder 15 rotates back into reference position, the output signal of last feed roller detector 17 can not stop the rotation of cylinder 15.Have only the hook or the groove 16 of cylinder 15 to receive workpiece veritably, workpiece is delivered on the feeding roller set 12, and after workpiece arrives charging detecting sensor 13 detection ranges, just can make charging detecting sensor 13 stop output signal, just might be when cylinder 15 rotate back into reference position once more, cylinder 15 just can stop operating.

As second embodiment of the present utility model, as can be seen from Figure 2, relay K A1 drives 21 work of a contactless switch, and the introducing of this contactless switch 21 makes can be according to the action of KA1 and KA2, make material loading drum drive 14 energized, feed roller 15 is rotated.Can also in such as the 3rd embodiment subsequently, control the rotation of feed roller 15 effectively according to the action of the other parts beyond KA1 and the KA2.

As mentioned above, after workpiece entered processing district 18 fully, when not had workpiece to exist before sensor 13, sensor 13 sent detection signal, by relay K A1 and contactless switch 21 feed roller 15 was rotated.When cylinder 15 rotations were got back to original position in one week, detector 17 detects projection 22 again, detector 17 outputs signal to relay K A2, this relay K A2 makes the relay K A1 disconnection with its interlock, contactless switch 21 makes the power failure of material loading drum drive 14, cylinder 15 stops operating, and waits for feed indication next time.

As the 3rd embodiment of the present utility model, as can be seen from Figure 3, sensor 13 is connected to a delay circuit 20.The signal of sensor 13 is given delay circuit 20, give relay K A1 by delay circuit 20 according to exporting a signal needed delay time again, and driving contactless switch 21 work, contactless switch 21 makes material loading drum drive 14 energized, and feed roller 15 is rotated.

Delay circuit 20 also can be arranged between relay K A1 and the contactless switch 21, makes material loading drum drive 14 energized, and feed roller 15 is rotated.

It is because the speed that workpiece feeds in the processing district is slower that delay circuit 20 is set, and the speed that workpiece is sent to forward by feeding roller set 12 is very fast, though the workpiece tail end is by charging detecting sensor 13, sensor 13 sensings exist less than workpiece, still just can deliver to workpiece on the feeding roller set 12 after will waiting certain hour, to prevent that afterwards workpiece from catching up with and clash into the fwd workpiece, causes workpiece to damage.But long delay can cause the waste of work-hours.The time that postpones depends on that speed that feeding roller set 12 is sent to forward and workpiece are in the processing district or the speed that feeds of treatment region.Therefore, make the delay time of delay circuit 20 adjustable second by 0-60.The user can regulate according to specific requirement at an easy rate at any time.

In the above-described embodiments, the diameter of last feed roller 15 can decide its size and rotating speed according to concrete workpiece situation, usually about 180-350mm.And its rotating speed only otherwise causing getting rid of of workpiece to take off just sees fit, and being generally per minute 15-20 changes.

Next door at last feed roller 15, a feeding platform can be set, allow workpiece roll according to the order of sequence one by one with a suitable gradient to cylinder 15, and when cylinder 15 is not rotated, the exit of feeding platform is just in time at the upside of the hook-shaped annex 16 of cylinder to be expected 15, and workpiece can automatically be rolled into from the platform in the middle of the hook-shaped annex 16.Because hook-shaped annex 16 designs to such an extent that can only hold a workpiece, has workpiece not roll into again.

Workpiece collecting region 19 at the rear portion of processing district, can a platform that have the gradient be set to the terminal of collecting region 19, after workpiece enters platform from collecting region 19, can be along the domatic downward rolling of flat-bed, automatically collected by following gathering-device, need not to artificially collect the workpiece of having processed.

Use after the feeding device of the present utility model, the material loading of long pole can automatically carry out, and a workman can manage many machines, has improved work efficiency greatly.

The description of the foregoing description does not constitute the restriction to the utility model protection domain.Any modification or the change made according to above-mentioned basic design; such as use different means of relay controlling control go up feed roller rotate, only change the shape that goes up feed roller or diameter, feeding platform and material-receiving device variation, use similar sensitive member or the like instead, these are still all within the utility model protection domain.
