  2. Description of the Related Art Conventionally, a supply device for a rod-shaped workpiece such as a shaft is known (see Patent Document 1). This rod-shaped workpiece supply device supplies the rod-shaped workpiece to a polishing device for finishing, supplies it to a cleaning device for cleaning, and supplies it to an inspection machine for measuring length, weight, and outer diameter. It is used for. As a rod-shaped workpiece supply device, there is an inclined tray that accommodates a large number of shafts, a slit is formed on the floor surface at the lowermost end of the tray, and a shaft selection that has a lift claw that passes vertically through this slit Equipment. While the lift claw of the shaft selector rises, only one rod-shaped workpiece stored in the tray is selected and placed, and in this state, the rod-shaped workpiece is placed on the carry-in side of the slope arranged obliquely above the shaft selector. The delivered bar-shaped workpiece is supplied to the subsequent apparatus.

Japanese Patent Laid-Open No. 11-240611

In the conventional bar-shaped workpiece supply device described above, a single bar-shaped workpiece can be reliably placed and transferred to the slope while the lift claw is raised. Each time the sheet is transported from the tray to the slope, it must move in the tray loaded with a large number of bar-shaped workpieces from the bottom to the top of the stroke. There is a problem that the sound when the workpiece interferes becomes noise.
In addition, the rod-shaped workpiece selection device needs to move the rod-shaped workpiece upward as well as to lift the lift pawl by pushing a plurality of rod-shaped workpieces, and there is a problem that extra driving force is required accordingly. is there.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rod-shaped workpiece supply device that can suppress noise and feed a workpiece from the tray to the outside with a small driving force.

In order to achieve the above-mentioned object, the invention described in claim 1 is directed to the carry-out side of the floor board (for example, the floor board 6 in the embodiment) inclined downward from the carry-in side to the carry-out side. A vertical wall (for example, the vertical wall 7 in the embodiment) is erected and disposed along the direction intersecting the conveying direction between the floor plate and the vertical wall (for example, the shaft W in the embodiment). A plurality of rows of trays (for example, tray 5 in the embodiment), and a slit for feeding the bar-shaped workpiece out of the tray between the lower end of the vertical wall and the floor plate (for example, a slit in the embodiment) 25) is formed, and a feeding device (for example, the stopper 33 and the cutting claw 45 in the embodiment) that feeds one by one while restricting the movement of the bar-shaped workpiece is provided in the slit, Supporting the rod-shaped workpiece placed on the second stage while leaving a space to be secured on the floor plate between the floor plate surface and the floor plate, waiting for the rod-shaped workpiece to wait on the first stage between the lit, A stop device (for example, the first control claw driving device 51, the first control claw driving device 51 in the embodiment, the first step) that can stop at the stop position and restrict movement of the first-stage bar-shaped workpiece adjacent to the loading-side of the second-stage bar-shaped workpiece. 2 control claw driving device 52) is provided with a control claw (for example, control claw 55 in the embodiment), and this control claw is provided so as to be movable from the stop position to the retreat position along the floor plate surface toward the carry-out side. By moving the claw to the retracted position and releasing the support by the control claw of the second-stage bar-shaped work, the movement of the first-stage bar-shaped work and the surrounding bar-shaped work to which the movement is restricted to the carry-out side can be performed. Tolerated.
With this configuration, when the control claw is at the stop position and the bar-shaped workpiece placed on the second level of the floor plate is supported by the control claw, the second level via the second level bar-shaped workpiece is supported. The movement of the first-stage rod-shaped workpiece adjacent to the carry-in side of the first-stage rod-shaped workpiece to the carry-out side is restricted, and the movement of the rod-shaped workpiece on the carry-in side is restricted from that of the first-stage rod-shaped workpiece. As a result, the plurality of first-stage bar-shaped workpieces before the slit positioned below the control claw and the second-stage bar-shaped workpiece are placed in a standby state in which the movement is restricted by the feeding device, so the first-stage bar-shaped member closest to the slit Are sequentially fed out from the slits one by one by the feeding device. In this way, after the control pawl and the plurality of first-stage bar-shaped workpieces located below the second-stage bar-shaped work are sequentially fed out, the control pawl moves from the stop position to the retracted position for a short period of time and moves to the carry-out side. When the second-stage rod-shaped workpiece whose movement is restricted is released, the first-stage rod-shaped workpiece and the surrounding rod-shaped workpiece that have been restricted to move to this second-stage rod-shaped workpiece move to the slit side and are in a standby state by the feeding device. At the same time, movement of the new second-stage bar-shaped work and the first-stage bar-shaped work adjacent to the second-stage bar-shaped work on the carry-in side are restricted by the control claw that has returned to the stop position again.

According to a second aspect of the present invention, the feeding device further includes a stopper (for example, the stopper 33 in the embodiment) configured to be able to regulate the movement of the rod-shaped workpiece that is next fed out from the slit, and further on the carry-in side of the stopper. It consists of a cutting claw (for example, a cutting claw 45 in the embodiment) configured to be able to regulate the movement of the next bar-shaped workpiece to the slit side.
By configuring in this way, the movement of the rod-shaped workpiece to be sent out first is restricted by the stopper, and then after the cutting claw is inserted between this rod-shaped workpiece and the rod-shaped workpiece to be fed next, the stopper is released. Then, the first bar-shaped work is fed out from the slit, the stopper is set again, and then the cut-out claw is retracted, thereby again regulating the unloading from the slit and waiting for a new bar-shaped work.

According to a third aspect of the present invention, the control claw and the cutout claw are arranged in a cutout portion (for example, the cutout for the control claw 57 and the cutout for the cut claw 47 in the embodiment) provided on the lower edge of the vertical wall. did.
By comprising in this way, the drive device which drives these including a control nail | claw and a cutting nail | claw can be arrange | positioned on the back side of a vertical wall.

In the invention described in claim 4, a plurality of sets of the stopper, the cutout claw, and the control claw are arranged in the longitudinal direction of the vertical wall corresponding to the length of the rod-shaped workpiece.
By comprising in this way, a rod-shaped workpiece can be controlled and cut out at an optimal support position in the longitudinal direction.

According to a fifth aspect of the present invention, there is provided a sensor for detecting whether or not there is a bar-shaped workpiece at a position of a stopper configured to be able to regulate the movement of the bar-shaped workpiece that is next fed out from the slit (for example, the sensor 37 in the embodiment). ).
With this configuration, when all of the plurality of bar-shaped workpieces waiting under the control claw have been carried out of the tray, this is quickly detected, the control claw is moved to the retracted position, and again below the control claw Can wait for the first-stage bar-shaped workpiece.

In the invention described in claim 6, the control claw is provided so as to be adjustable in the height direction with respect to the floor board surface.
By comprising in this way, it becomes possible to set the support point with respect to the 2nd step | paragraph rod-shaped workpiece in the optimal position.

According to the invention described in claim 1, each of the rod-like workpieces is quietly moved one by one by a short stroke operation in which the control claw moves a small distance from the stop position to the retracted position and returns to the stop position again. In addition, there is an effect that the driving force can be reduced to feed out from the slit. In other words, the control claw moves backward only with a short stroke that only releases the restraint of the second-stage bar-shaped workpiece that restricted the movement, so that the force applied to the surrounding bar-shaped workpiece by this movement is minimized. In addition, since the movement distance of the control claw itself is small, it is possible to suppress damage to the rod-shaped workpiece, to suppress the generation of noise even in the subsequent return movement to the stop position, and to minimize the driving force.
According to the second aspect of the present invention, first, the movement of the bar-shaped work to be fed next is restricted by the stopper, and then the cutting claw is inserted between the bar-shaped work and the bar-shaped work to be fed next, and then the stopper The first bar-shaped workpiece is fed out from the slit, the stopper is set again, and the cutting claw is retracted to regulate the unloading from the slit again to wait for a new bar-shaped workpiece. Can be reliably delivered out of the slit one by one.
According to the third aspect of the present invention, since the driving device for driving the control claw and the cutting claw, including the control claw and the claw claw, can be disposed on the back side of the vertical wall, it interferes with the loading of the rod-shaped workpiece in the tray. There is an effect to prevent.
According to the invention described in claim 4, since the rod-like workpiece can be restricted and cut out at the optimum support position in the longitudinal direction, there is an effect that even rod-like workpieces having different lengths can be handled.
According to the fifth aspect of the present invention, when all of the plurality of bar-shaped workpieces waiting under the control claw are carried out of the tray, this is promptly detected, and the control claw is moved to the retracted position and moved to the stop position. Since the first-stage bar-shaped workpiece can be made to stand by again under the control claw, the bar-shaped workpiece can be carried out of the tray without being continuously interrupted.
According to the sixth aspect of the present invention, the support point for the second-stage bar-shaped workpiece can be set at the optimum position. There is an effect that the movement of the first-stage rod-shaped workpiece adjacent to the second-stage rod-shaped workpiece on the carry-in side to the carry-out side can be reliably restricted via the second-stage rod-shaped workpiece.

Here, the plate 10 includes a side plate 10 s that covers the side, an upper plate 10 u that covers the upper portion, and a front plate 10 z that covers the front upper portion of the vertical wall 7 along the vertical wall 7.

2 is a perspective view of the shaft supply device 1 viewed from the carry-out side, FIG. 3 is a plan view, FIG. 4 is a side view, and FIG.
As shown in FIGS. 1-4, the floor board 6 of the shaft supply apparatus 1 is a member extended toward the carrying-out side from the carrying-in side. In FIG. 2, the description of the plate 10 is omitted.

A right side plate 11 is attached to the floor plate 6 on the right side toward the carry-out side and extending in the vertical direction at a side edge extending from the carry-in side to the carry-out side. A flange portion 13 provided at the lower edge of the right side plate 11 is fixed to the support frame 3 with bolts 14 below the floor plate 6.
The floor plate 6 extends to the left side toward the carry-out side, extends downward in the range from the carry-in side to the front position of the vertical wall 7, and extends to the vertical direction in the range from the front side of the vertical wall 7 to the carry-out side. The plate 12 is fixed. A flange portion 13 is also formed at the lower edge of the left side plate 12, and the flange portion 13 is fixed to the support frame 3 with bolts 14.

The upper edge of the right side plate 11 and the left side plate 12 on the carry-out side is cut obliquely downward from the vertical wall 7 toward the carry-out side. Since the rear edge of the left side plate 12 extends to the front of the vertical wall 7, an opening 15 is formed by the rear edge of the left side plate 12 and the floor plate 6, and the shaft W is supplied from the opening 15. ing. Here, the front wall 16 is attached to the front edge portion on the carry-in side of the floor board 6 at three positions with a predetermined interval so that the shafts W arranged along the direction intersecting the transport direction can be stacked in a plurality of stages. ing.
The shaft W is a hollow tapered member having a length of 800 to 1300 mm, a diameter of 10 to 25 mm on the thick side, and a diameter of 7 to 15 mm on the thin side. Is loaded so that the end on the narrow side is in contact with the right side plate 11.

  On the right side plate 11 and the left side plate 12, a vertical wall 7 that is spaced from the central portion in the transport direction of the floor plate 6 and slightly spaced from the upper surface of the floor plate 6 is erected upward. Specifically, a side plate bracket 17 having an L-shaped cross section is attached to the inner side surfaces of the right side plate 11 and the left side plate 12, and bolts and nuts 19 (see FIG. 1) are attached to three mounting holes on the wall facing the inner side of the side plate bracket 17. The three long holes 18 at the side edges of the vertical wall 7 are fixed so that the position in the height direction can be adjusted.

  Here, an L-shaped positioning bracket 20 is provided on the outer side surfaces of the right side plate 11 and the left side plate 12 so that the front ends extend inward. Further, a lifting bracket 21 is provided on the upper surface of the back surface of both side portions of the vertical wall 7 so as to face the front end portion of the positioning bracket 20 from below. An adjustment bolt 22 is rotatably supported at the tip of the positioning bracket 20, and the adjustment bolt 22 is pulled up and screwed into the bracket 21 from the upper side so that the vertical wall 7 extends to the right side plate 11 and the left side plate 12 in the vertical range of the long hole 18. On the other hand, the height can be adjusted in the vertical direction. Thereby, the space | interval of the slit 25 formed between the vertical wall 7 and the floor board 6 can be finely adjusted according to the diameter of the shaft W supplied. Specifically, the width is set such that the first-stage shaft W can pass and the second-stage shaft W cannot pass.

  Here, the floor board 6 is disposed so as to be inclined about 10 degrees downward toward the carry-out side so that the shaft W can be smoothly conveyed. Further, the floor plate 6 is disposed with an inclination of 4 degrees so that the left side is lower than the right side because the shaft W is placed with the diameter increasing toward the left side plate 12. Further, the vertical wall 7 is arranged so that the upper end portion thereof is inclined 15 degrees toward the carry-in side with respect to the vertical direction, so that the shaft W can be smoothly introduced into the lower part of the vertical wall 7 on the carry-out side.

  As shown in FIG. 5, two support guides 23, 23 for supporting the shaft W with a small contact area are provided on the upper surface of the floor plate 6 at a predetermined interval toward the carry-out side. The shaft W can be reliably supported on both of the short shafts W. Specifically, it can be set at the optimum position by setting it at the position shown in FIG. 5 or by moving the right support guide 23 closer to the left support guide 23 in FIG.

And the stopper nail | claw 24 which regulates the movement of the shaft W is provided in the edge part by the side of carrying out of the support guides 23 and 23. As shown in FIG.
The stopper claw 24 is the final position where the shaft W is transferred to the shaft inspection machine S at the carry-out end of the shaft supply device 1, and the shaft W on the stopper claw 24 is taken out by a gripping arm (not shown) of the shaft inspection machine S. It is carried out to the weight measurement part G.
On the right side of each support guide 23, a stopper member 26 that temporarily stops the movement of the shaft W on the support guide 23 is provided in a slightly retractable manner on the carry-in side of the stopper claw 24.
A slit 25 is formed between the lower end of the vertical wall 7 and the floor plate 6 to feed the shaft W to the outside of the tray, that is, to the shaft inspection machine S in the next stage (see FIG. 2).

  6 is a perspective view of the vertical wall as viewed from the carry-out side, and FIG. 7 is a rear view of the vertical wall. As shown in FIGS. 6 and 7, the vertical wall 7 is provided with three elongated holes 18 on the left and right side edges in the vertical direction, and the portion where the elongated holes 18 are formed is formed thin on the carry-in side, Here, the wall portions facing the inner side of the side plate brackets 17 and 17 attached to the right side plate 11 and the left side plate 12 are superposed so as to be relatively guideable in the vertical direction. The lower edge of the vertical wall 7 constitutes the upper portion of the slit 25, and a plurality of notches are formed in the lower edge, and a plurality of devices are arranged here.

  Specifically, the first stopper driving device 31 and the first clipping claw are arranged on the rear surface side of the vertical wall 7 from the left side (right side toward the carry-out side) to the right side (left side toward the carry-out side) in FIGS. The drive device 41 and the first control claw drive device 51 are arranged in this order, and the second cutout claw drive device 42 is sandwiched on the right side of the drive device 41, the third cutout claw drive device 43, and the second control claw. Drive devices 52 are arranged in order. The second cut-out claw driving device 42 is used only when the short shaft W is used, and is not driven when the long shaft W is used.

  The 1st stopper drive device 31 is supporting the stopper 33 so that protrusion is possible. The stopper 33 is supported by the air cylinder 35 so as to protrude downward from the lower edge of the vertical wall 7 while being guided slidably by the guide 34. The stopper 33 restricts the movement of the shaft W reaching the front of the slit 25 at the protruding position, and releases the shaft W at the retracted position to allow the movement to the next stopper member 26 along the support guide 23. A sensor notch 36 is formed in the vertical wall 7 at a position just beside the stopper 33, and a sensor 37 for detecting whether or not the shaft W exists in the sensor notch 36 is exposed. The sensor 37 is a photoelectric sensor, but other than that, a reflective sensor or a microswitch can be used. Here, the support portion 38 of the air cylinder 35 is bolted to the vertical wall 7 through a long hole 39 so that the vertical position can be adjusted.

  Further, the first stopper driving device 31 is fixed to the back plate 40a by applying the back plate 40a to the notch 40 provided in the vertical wall 7, and is positioned on the carry-in side as much as the shaft W is thinned. The end of the shaft W on the narrow side on the carry-in side is received. The second stopper driving device 32 is different from the first stopper driving device 31 except that the sensor 37 is provided in the sensor notch 36 except that the second stopper driving device 32 is directly attached to the vertical wall 7 instead of the back plate. Since they are the same, the same parts are denoted by the same reference numerals and description thereof is omitted.

  The first cut-out claw driving device 41 is arranged on the right side of the first stopper driving device 31 and is inclined vertically with the lower side directed toward the carry-in side via an L-shaped bracket 44 attached to the rear surface of the vertical wall 7. It is supported on the rear surface side of the wall 7, and is supported by the air cylinder 35 so that the claw 45 can project along the guide 46 so as to fit on the rear surface side of the vertical wall 7 at the standby position. The cut-out claw 45 is disposed in a cut-out notch 47 provided on the vertical wall 7 and protrudes from here toward the carry-in side toward the obliquely lower front side (load-in side).

  Here, the bracket 44 is bolted to the vertical wall 7 by a long hole 48 so that the vertical position can be adjusted. The cut-out claw 45 restricts the movement of the shaft W, which is adjacent to the shaft W that is restricted by the stopper 33 on the carry-out side, and is sent out to the slit 25 side at the protruding position. At the retracted position, the cut-out pawl 45 releases the shaft W and allows the next shaft W to move toward the stopper 33 along the support guide 23. Here, since the cutting claw 45 is inserted so as to be divided between the shaft W stopped by the stopper 33 and the shaft W to be carried out next, the tip end portion is formed to be tapered (in FIG. 6). (Shown with a dashed line). The feeding device is mainly constituted by the stopper 33 and the cutting claw 45. Note that the second cut-out claw drive device 42 and the third cut-out claw drive device 43 are the same as the first cut-out claw drive device 41, and therefore, the same parts are denoted by the same reference numerals and description thereof is omitted.

  The first control claw drive device 51 is disposed on the right side of the first cut-out claw drive device 41 and is supported substantially horizontally with the front side facing the carry-in side via the bracket 54, and a triangular control claw 55 is moved by the air cylinder 35. A guide 56 is supported so as to be movable from a stop position to a retracted position. The stop position is a position that is about 40 mm from the vertical wall 7 toward the carry-in side, and the retreat position is a position substantially in front of the vertical wall 7 (about 40 mm by stroke). The control claw 55 is disposed in a control claw notch 57 provided on the vertical wall 7 and protrudes from here along the floor plate 6 toward the carry-in direction.

  Here, the bracket 54 is bolted to the vertical wall 7 by a long hole 58 so that the position in the vertical direction can be adjusted. The apex angle of the control claw 55 is set to about 35 degrees, and the width dimension is set to about 90 mm. A control claw 55 of the second control claw driving device 52 described later has a width dimension of about 30 mm and is narrower than the control claw 55.

  As shown in FIG. 8A, the control claw 55 is on the carry-in side of the slit 25 at the protruding stop position, and waits for four shafts W in the first stage on the floor board 6 between the control board 55 and the floor board 6 surface. The shaft W mounted on the second stage is supported at the tip while leaving a space to be secured, and the first stage shaft W adjacent to the carry-in side of the supported second stage shaft W is carried out. Restrict movement to the side. That is, when the tip end of the control claw 55 comes into contact with the second stage shaft W at the stop position, the shaft W receives a force on the carry-in side, so that the first-stage shaft W adjacent to the carry-in side moves to the carry-out side. Therefore, the four shafts W in the standby position are not subjected to any force from the other shaft W from the upper side and the carry-in side.

When the control claw 55 moves to the retracted position, it releases the movement restriction of the first stage shaft W, which has been restricted by the second stage shaft W, in order to release the second stage shaft W that has been supported so far. In order to release the first stage shaft W, the first stage shaft W and the surrounding shaft W fall to the first stage and move to the slit 25 side, and the four shafts W are restricted by the stopper 33 in the vicinity of the slit 25. It will be in the state.
When the control claw 55 moves forward again and returns to the stop position, the tip of the control claw 55 moves the new second stage shaft W and the first stage shaft W adjacent to the second stage shaft W on the carry-in side. regulate.

Here, the control claw 55 is formed in a triangular shape in a side view, the lower surface 59 is formed in parallel with the floor board 6, the upper surface 60 is a hypotenuse inclined so as to descend downward toward the carry-in side, and the upper surface 50. Smoothly guides the shaft W loaded on the upper part.
Further, at the stop position, the front end of the control claw 55 abuts on the second stage shaft W loaded on the floor board 6 to restrict movement, and is adjacent to the abutted second stage shaft W on the carry-in side. The eye shaft W is supported via the second-stage shaft W, and is set to a height position at which the movement of the second-stage shaft W and the first-stage shaft W to the carry-in side can be restricted.

  It should be noted that the first control claw drive device 51 is independent of the shaft W having a short length, so that the control claw 55 has a wider width than the second control claw drive device 52. Since the second control claw driving device 52 is the same as the first control claw driving device 51, the second control claw driving device 52 is the same as the first control claw driving device 51, and thus the same reference numerals are given to the same parts. The description is omitted.

  As shown in FIG. 6, an L-shaped sensor bracket 61 extending to the carry-out side is provided adjacent to the left side of the first stopper driving device 31 and the second stopper driving device 32, and a shaft W is attached to the tip of the sensor bracket 61. A sensor 62 for detecting whether or not it exists is attached. The sensor 62 detects the shaft W that moves to the carry-out side of the vertical wall 7 and is restricted by the stopper member 26. The sensor 62 is also fixed to the vertical wall 7 so that the vertical position can be adjusted by inserting a bolt into a long hole 63 formed in the vertical direction of the sensor bracket 61.

  Next, a case where a long shaft W is supplied to the shaft inspection machine S will be described with reference to FIG. First, the interval of the slit 25 between the vertical wall 7 and the floor board 6 is adjusted corresponding to the shaft W to be measured. For adjustment, the bolts and nuts 19 of the long holes 18 provided on both sides of the vertical wall 7 are loosened, and the adjustment bolts 22 fixed to the right side plate 11 and the left side plate 12 are screwed into the positioning bracket 20. When the vertical wall 7 is rotated in the direction, the vertical wall 7 is moved upward via the lifting bracket 21 and the width dimension of the slit 25 is adjusted to be large, and conversely, when the adjustment bolt 22 is rotated in the direction of loosening with respect to the positioning bracket 20. The vertical wall 7 moves downward through the lifting bracket 21 and the width dimension of the slit 25 is adjusted to be small. Thereafter, when the height position is determined, the bolts and nuts 19 loosened in the long holes 18 are tightened to fix the vertical wall 7 to the side plate bracket 17.

  Next, the height of the control claw 55 of the first control claw drive device 51 and the second control claw drive device 52 is adjusted according to the shaft W. The control claw 55 is supported by the tip of the shaft W loaded on the second stage on the floor plate 6 so as to prevent the second stage shaft W from moving toward the carry-out side. This also prevents movement of the first stage shaft W adjacent to the stage shaft W on the carry-in side to the carry-out side.

  Therefore, if the tip of the control claw 55 is too high, a force for supporting the first-stage shaft W cannot be applied via the second-stage shaft W, and if the tip of the control claw 55 is too low. This time, the second stage shaft W rides on the upper surface 60 of the control claw 55, and the adjacent first stage shaft W cannot be supported. Therefore, it is necessary to adjust the height dimension of the control claw 55.

  The height of the control claw 55 is adjusted by loosening the bolts of the long holes 58 of the bracket 54 of the first control claw drive device 51 and the second control claw drive device 52, and the first control claw drive device 51 and the second control claw drive device 52. The bolt of the long hole 58 may be tightened again after the height of itself is adjusted to the optimum position in the vertical direction. If necessary, the first stopper driving device 31 and the second stopper driving device 32 are adjusted in the vertical direction with the support portion 38 through the long hole 39, and the first cutting claw driving device 41 and the second cutting claw driving device 42 ( When the short shaft W is used), the third cut-out claw driving device 43 is adjusted in the vertical direction by the long hole 48 of the bracket 44.

In this state, a plurality of shafts W to be measured are accommodated in the shaft stacking portion 8 of the tray 5. The shaft W is loaded on the support guide 23 on the floor plate 6 from the opening 15 of the left side plate 12 with the large diameter side facing the left side plate 12.
At this time, as shown in FIG. 8A, the control pawl 55 is in the stop position protruding from the vertical wall 7 to the carry-in side by the first control pawl drive device 51 and the second control pawl drive device 52, and the first stopper The stopper 33 is protruded downward by the driving device 31 and the second stopper driving device 32.
In addition, the first cut-out claw driving device 41 and the third cut-out claw drive device 43 are in a state in which the cut-out claw 45 protrudes downward.

In such an initial position, a space is formed between the lower surface 59 of the control claw 55 and the floor plate 6, and the front portion of the first stage shaft W whose movement is restricted by the second stage shaft W described above is formed here. The four shafts W are placed in a standby state.
In this state, as indicated by a chain line in FIG. 8A, the stopper 33 is retracted upward by the first stopper driving device 31 and the second stopper driving device 32. Then, since the frontmost shaft W among the four shafts W in the standby state is released from the restriction of the stopper 33, the shaft W moves to the carry-out side on the inclined floor plate 6, strictly on the support guide 23. Then, it passes through the stopper member 26 that has been retracted, moves to the position of the stopper claw 24, stops, and waits for the gripping arm of the shaft inspection machine S to be taken out.

  When the sensor 37 detects that the shaft W does not exist, the stopper 33 is lowered, and after the stopper 33 is lowered, the clipping claws 45 of the first clipping claw driving device 41 and the third clipping claw driving device 43 are retracted. When it descends again, as shown by a chain line in FIG. 8B, three shafts W remain.

  Next, when the stopper 33 is retracted upward as shown by a solid line, the frontmost shaft W among the three shafts W in the standby state is similarly sent out to the carry-out side. Then, since the sensor 37 no longer detects the shaft W, the stopper 33 is lowered, and the claw 45 is retracted upward and then lowered again, as shown in FIG. 8C, the two shafts W are in the standby state. Become.

  Then, the above operation is repeated, and as shown in FIG. 8 (d), the sensor 37, together with a counter (not shown), indicates that all four waiting shafts W between the control claw 55 and the floor board 6 have been carried out. Upon detection, as shown in FIG. 8 (e), after the cutting claw 45 is retracted upward (solid line position), the control claw 55 moves to the retracted position (solid line position), as shown in FIG. 8 (d). Since the second-stage shaft W that has been supported by the tip of the control claw 55 until then is released, the first-stage shaft W and the surrounding shaft W that have been regulated by the second-stage shaft W are slit. It is allowed to move to the 25th side and stops at the stopper 33 along with the first stage of the floor board 6.

  When the control claw 55 moves forward from the solid line position in FIG. 8 (e) to the stop position shown by the chain line after the control claw 55 moves backward by a small distance, as shown in FIG. 8 (f), it moves forward. While pushing the second-stage shaft W with the tip of the control claw 55 positioned closest to it or pushing the second-stage shaft W up to the upper surface 60, the second-stage shaft W to be withdrawn is pressed. The first stage shaft W adjacent to the second stage shaft W on the carry-in side is supported.

Thereby, the four shafts W carried out next between the control claw 55 and the floor board 6 are in a standby state without receiving a load from the outside.
Thereafter, the cut-out claw 45 is moved down to the state shown in FIG. 8A, and the same operation is repeated again.

Accordingly, the control pawl 55 moves by a small distance from the stop position to the retracted position and returns to the stop position again, so that the shaft W is moved one by one, quietly and with less driving force. 25 can be sent out.
In other words, the control claw 55 moves backward only with a short stroke that only releases the restraint of the second stage shaft W that restricts the movement, so that the force received by the surrounding shaft W is minimized. In addition, since the moving distance of the control claw 55 itself is small, damage to the shaft W can be reduced, noise can be suppressed, and driving force can be minimized.

  In particular, when the control claw 55 moves to the stop position, most of the second stage shaft W rides on the upper surface 60 of the control claw 55, and finally the second stage before the control claw 55 reaches the stop position. Since the number of shafts W that move along with the movement of the control claw 55 is small because it is in contact with and supported by the eye shaft W, the shaft W simply moves on the upper surface 60 of the control claw 55. As compared with the conventional case where the shaft W is moved, damage and noise generation to the shaft W can be suppressed.

  When the shaft W is sent out from the slit 25 to the carry-out side, the movement of the shaft W to be sent next is restricted by the stopper 33, and then a cutting claw 45 is inserted between the shaft W and the shaft W to be fed next. After that, the stopper 33 is released, the first shaft W is sent out from the slit 25, the stopper 33 is set again, and then the cutting claw 45 is moved backward to restrict the carry-out from the slit 25 again. Since it can be made to wait, the shaft W can be reliably sent out of the slit 25 one by one.

  Further, the control claw 55 and the cutout claw 45 are arranged in a control claw cutout 57 and a cutout claw cutout 47 provided on the lower edge of the vertical wall 7, so that a first control claw driving device 51 that drives them is provided. Since the second control claw drive device 52, the first cutout claw drive device 41, the second cutout claw drive device 42, and the third cutout claw drive device 43 can be arranged on the rear side of the vertical wall 7, the shaft of the tray 5 In the stacking unit 8, the first control claw drive device 51, the second control claw drive device 52, the first cutout claw drive device 41, the second cutout claw drive device 42, and the third cutout claw drive device 43 are loaded on the shaft W. Is prevented from getting in the way.

  And although it demonstrated by the case where the long shaft was used, when the short shaft W as shown in FIG. 7 was used, the 1st stopper drive device 31, the 1st cutting nail drive device 41, The shaft W may be supplied to the shaft inspection machine S using only the second cut-out claw driving device 42 and the first control claw driving device 51. As a result, the movement can be restricted and cut out at the optimum support position according to the length of the shaft W, so that even shafts W having different lengths can be handled. In addition, since the minimum necessary equipment is used, the power is low and the noise is reduced.

  By providing the sensor 37 for detecting whether or not the shaft W exists at the position of the stopper 33, when all of the plurality of shafts W waiting under the control claw 55 are carried out of the tray 5, this is quickly detected. In this case, the control claw 55 is moved to the retracted position and returned to the stop position, and the first stage shaft W can be made to stand by below the control claw 55 again. 5 can be carried out.

  Further, both the first control claw driving device 51 and the second control claw driving device 52 are fixed to the vertical wall 7 so as to be movable up and down by a long hole 58 of the bracket 54, and in the height direction with respect to the upper surface of the floor board 6. Since the position can be adjusted, the support point with respect to the two-stage shaft W with which the tip of the control claw 55 abuts can be set to the optimum position. Thereby, even if the diameter of the shaft W to be handled changes, the carry-out side of the first-stage shaft W adjacent to the second-stage shaft W on the carry-in side via the second-stage shaft W correspondingly. The movement to the can be reliably regulated.

  In particular, when handling shafts with a tapered shape, the shafts W are different in loading height and loading length at both ends, so that the shafts W are easily locked to each other at the end portion on the larger diameter side. It is effective to use this shaft supply device 1 that effectively uses a bridge in which the stage shaft W restricts and locks the movement of the first stage shaft W.

  The present invention is not limited to the above embodiment. For example, as long as the shaft supply device needs to supply shafts one by one, in addition to the shaft inspection device, the shaft cleaning device and the shaft polishing device It can be provided on the carry-in side of various devices such as a shaft packing device. Further, the rod-shaped workpiece is not limited to the shaft of the golf club, and the solid rod-shaped member can be used for various workpieces such as a rod-shaped member that is not tapered and a piping material.
