Secondly, the first action example of the bar conveying machine 2 of present embodiment is described.At first, rear rail sections 22 is positioned at primary feed position shown in Figure 2.Primary feed parts 29 are sent to primary feed with in the rearward end of rail sections 24.
At first, on the material shelf 8 not under the state of mounting bar, by making pressing component 12 move to preceding inlet side, with downstream 38 alignment of the face 13 and the frame face 10 in pressing component 12 downstreams, with reference position, the position of the pressing component 12 of this moment as servomotor 44.Specifically, making the pressing component drive motor by controller 19 is servomotor 44 actions, and the rotation of servomotor 44 is delivered to pressing component with driving shaft 58 on sprocket wheel 66 and pressing component with annular link chain 68 by pressing component.Pressing component is delivered on the lead screw shaft 52 by cylinder turbine and worm secondary 60 and cylinder turbine 62 with the rotation of driving shaft 58.Thus, being installed on pressing component 12 following nuts 54 advances.To along symmetrically arranged two the snap bolt transmission devices 56 of the length direction of pressing component 12 be located at linear guide 46 guiding at two ends, pressing component 12 moves abreast with respect to guide rail 6.End sensor 42 detects pressing component 12 if advance, and then servomotor 44 is stopped, and at this moment, the position by position detecting device (servomotor) 44 detections pressing component 12 at this moment transfers signal to controller 19 simultaneously.At this moment, downstream 38 alignment of the face 13 of pressing component 12 and frame face 10.As long as the reference position of servomotor 44 is skew not, do not need all to carry out this action at every turn.
Then, make pressing component 12 retreat into can be on frame face 10 space of mounting bar.For example, pressing component 12 retreats until retreating end sensor 40 and detects pressing component 12.Specifically, also can be opposite with above-mentioned explanation, make servomotor 44 reversings.
Secondly, the operator with bar W (green wood) mounting on material shelf 8, with bar one row ground and come on the material shelf 8.Because the frame face tilts upward towards bar supply direction downstream, one lists places bar on the frame face 10 of material shelf 8 near pressing component 12 sides of upstream side.In addition, the operator is from the diameter of input unit 18 input bars.So far finish preparatory process.
Then, when making pressing component 12 advance to bar supply direction downstream once more, the bar of the upstream side parts 12 that are pressed are pressed to downstream direction, and thus, the whole downstream of the bar of a row ground mounting on frame face 10 moves.Bar moves abreast with respect to guide rail 6.The downstream 38 that surpasses frame face 10 at the bar of sensing downstream by sensor 16, when guide rail 6 extrudes, controller 19 stops servomotor 44, obtain the distance (first distance) of downstream based on the signal of pressing component position detecting device 44 to the face 13 in pressing component 12 downstreams, and with its storage.
Fig. 5 (a)～Fig. 5 (d) is that expression sensor 16 detects by the key diagram of the bar that extrudes from frame face 10.Before extruding from frame face 10 to the bar in downstream, the arm 16a of sensor 16 remains on pressured invariant position (Fig. 5 (a) and Fig. 5 (b)).When bar surpassed downstream 38, bar was along bar spigot surface 37 quick rotation, and simultaneously, the arm 16a that makes sensor 16 is pivot moving (Fig. 5 (c)) downwards.Thus, detect bar by situation about extruding from frame face 10.When bar by bar spigot surface 37 when guide rail 6 falls, the arm 16a of sensor 16 returns pressured position (Fig. 5 (d)).
Then, controller 19 is read the distance from the downstream 38 of frame face 10 to next root bar of corresponding diameter of rod, from first distance it is deducted, and removes this difference by the diameter of bar.Thus, can obtain the quantity of the bar on the frame face 10.Controller 19 is shown in display unit 17 with the quantity of the bar obtained.
Secondly, will deliver to bar processing unit (plant) (not shown) to the bar B of guide rail 6 supplies by feeding wedge 30.Illustrate that with reference to Fig. 6 (a)～(g) this gives.At the initial position of guide rail 6, rear rail sections 22 is positioned at the primary feed position, that is, primary feed aligns on coaxial with the place ahead rail sections 20 and bar processing unit (plant) with rail sections 24.According to the order that has illustrated bar W is supplied to the place ahead rail sections 20 and the primary feed usefulness rail sections 24 (Fig. 6 (a)) from material shelf 8.
Secondly, carry out the primary feed of bar W.Controller 19 drives primary feed member driving units (not shown), primary feed parts 29 downstream that the annular link chain (not shown) with the primary feed member driving unit is linked, and promptly the bar processing unit (plant) moves.By the rear end of pushing bar W, bar W is moved to the position shown in (Fig. 6 (b)) by primary feed parts 29 downstream.The rearward end of bar W is controlled by clamping plate (not shown), and restriction bar W moves to length direction.
Secondly, utilize guide rail shifter 28 that rail sections 22 edges in rear are moved laterally to the secondary feed position, with secondary feed downstream rail sections 26 and 20 alignment (Fig. 6 (c)) of the place ahead rail sections.
Secondly, carry out the secondary feed of bar W.Controller 19 drives feeding wedge drive units 32, and feeding wedge 30 downstream that the annular link chain (not shown) with feeding wedge drive unit 32 is linked move.If feeding wedge 30 is advanced, the rearward end insertion of bar W is located in the mechanical chuck (Off ィ Application ガ one チ ヤ Star Network) (not shown) of feeding wedge 30 end of downstream side, then unclamp clamping plate.Then, forwards give bar, processing bar (Fig. 6 (d)) by feeding wedge 30.After the bar process finishing, make 32 reversings of feeding wedge drive unit, make feeding wedge 30 retreat (Fig. 6 (e)).
Secondly, make rear rail sections 22 return primary feed position (Fig. 6 (f)) from the secondary feed position.Then, drive primary feed member driving unit (not shown), the primary feed parts 29 that the annular link chain (not shown) with the primary feed member driving unit is linked move to the rearward end (Fig. 6 (g)) of primary feed with guide rail 24.In addition, the rearward end of rail sections 20 is formed for the clout processing usefulness hole (not shown) of discarded clout after process finishing forwardly, make it open towards rear rail sections 22, clout is handled by this clout and is used the hole, abandons to the below of primary feed with rail sections 24.
Then, carry out above-mentioned operation outside the preparatory process repeatedly.
The second action example of bar conveying machine of the present invention then, is described.By this second action example, even the operator is not input to input unit 18 with the diameter of bar, also can be in the quantity of the bar on the display material frame 8 on the display unit 18.The second action example is removed the operator and needn't be imported the diameter of bars from input unit 18, with respective action example to preparatory process be common.
Secondly, identical with the first action example, when making pressing component 12 advance to bar supply direction downstream, the bar of upstream side is pressed towards downstream direction by pressing component 12, thus, moves in the whole downstream of the bar of frame face 10 previous column mountings.The downstream 38 that surpasses frame face 10 at the bar of sensing downstream by sensor 6, when situation that guide rail 6 extrudes, controller 19 stops servomotor 4, based on the distance of obtaining from the signal of position detecting device (servomotor) 44 from frame face 10 downstream 38 to the face 13 in pressing component 12 downstreams (first distance), and with its storage.Then, as the illustrated ground of the first action example, carry out primary feed and secondary feed to the bar of guide rail 6 supplies.Then, pressing component 12 downstream are moved, the downstream 38 that surpasses frame face 10 at the bar of sensing the downstream of next root by sensor 6, when situation that guide rail 6 extrudes, controller 19 stops servomotor 44, based on the distance of obtaining from the signal of position detecting device (servomotor) 44 from frame face 10 downstream 38 to the face 13 in pressing component 12 downstreams (second distance), and with its storage.
Then, controller 19 is obtained the diameter of bar according to the difference of first distance and second distance.Controller 19 deducts the distance from the downstream 38 of frame face 10 to next root bar of corresponding diameter of rod from second distance, remove this result by the diameter of bar.Thus, can obtain the quantity of the bar on the frame face 10.Controller 19 is shown in display unit 17 with the quantity of the bar obtained.
Secondly, identical with the first action example, carry out the primary feed and the secondary feed of bar.
Operation afterwards is except that the diameter of the bar of the diameter replacement input of using the bar of obtaining by calculating, and is identical with the first action example.
