As shown in FIG. 9, when the lifting member 154 moves from the retreat position 154a to the lifting position 154b around the first pivot 152, that is, the operation lever 156 moves from the upper position 156c to the lower position 156d.
- the locking position 156e of the operation lever 156 is arranged laterally with respect to the lower position 156d.
- the side wall 160 on which the locking device 158 is formed has a notch 180a along the first path for moving the operation lever 156, and a notch 180b along the second path. .
- the notch 180a along the first path extends vertically so that the operation lever 156 can move from the upper position 156c to the lower position 156d.
- the notch 180b along the second path extends laterally from the lower end of the first path, then extends upward, and terminates at a locking position 156e for locking the operation lever 156.
- the terminal end constitutes an abutment surface 182 that extends across the operation lever 156 at the engagement position 156e for engaging the operation lever.
- the first route and the second route are substantially J-shaped as a whole.
- the side wall 160 is provided with a cover 184 slidable along the side wall 160 between a closed position (not shown) for covering the notch and an open position for exposing the notch.
- the operation of the bar feeder according to the third embodiment is similar to the operation of the bar according to the first embodiment except that the lifting member does not interlock with the swinging member and is operated by the controller and the operation of the lifting device. This is the same as the operation of the material feeder. Further, the operation of the lifting member is common to the operation of the bar feeder of the second embodiment described above. Therefore, only the operation of the lifting device will be described below, and the description of the common portions will be omitted.
- the cover of the side wall 160 is not covered.
- the operating lever 156 is attached to the pivot bracket 174 of the lifting member 154 from outside the side wall 160 in order to move the first 184 to the open position and use the bar lifting device 150. Specifically, by inserting the base end 156a of the operation lever 156 into the hole 176 of the pivot bracket 174 and engaging the slip-off preventing member 178 with the groove 158b of the operation lever 158, the operation lever 156 is Get out of the way.
- the lifting member 154 is pivoted about the first pivot 152 from the retreat position 154a to the lifting position 154b. .
- the bar B in the guide rail 30 is supported by the support portion 164 of the lifting member 154 and lifted toward the extraction space 79.
- the operation lever 156 is pivoted in the lateral direction about the second pivot 172 until the locking position 156e is locked by the locking device 158. Move along the accompanying second path.
- the operation lever 156 In the normal mode in which the bar B is supplied to the guide rail 30, the operation lever 156 is moved along the second path and the first path to return to the upper position 156c. Then, the operating lever 1 56 is pulled out of the pivot bracket 174, and the cover 184 is moved to the closed position.
- controller 24 is provided in the bar feeder 2, but control may be performed by a controller provided in the bar feeder 4.
- the swinging member 66 is in the upper position (0 ° position) and the lower position. It is configured so as to reciprocate with the position (120 ° position), which is advantageous in that it can be used without changing the control program of the indexing plate.
- the swing member 66 needs to be kept near the material shelf 20 from the viewpoint of shortening the operation time.
- the swinging member 66 does not necessarily need to wait at the above-described upper position (0 ° position). Therefore, the waiting of the swinging member 66 may be performed at a position near the material shelf 20 that has been reversed and returned from the lower position. May also wait at a lower position.
- the contour of the cam surface 76 for controlling the vertical movement of the bar pushing-up member 78 of the bar removing mechanism 68 is changed from the material shelf 20 in accordance with the movement of the swinging member 66.
- the bar pushing member 78 may be changed so that it protrudes and retracts.
- the control of the actuator 132 for causing the movement of the bar pushing-up member 78 may be performed in accordance with the movement of the swinging member 66.
- the position of the swinging member 66 at the time of removing the bar is not limited to the above-described position as long as the position is not above the guide rail 8, and may be a position further rotated forward. Further, in the above embodiment, the upper position is set to 0 °, the receiving position (upper position) of the bar is set to 60 °, and the lower position where the bar is thrown into the guide rail 8 is set to.
- the force relative position at the 120 ° position can be changed as appropriate without necessarily having to be at 60 °.
- the bar regulating member 54 and the regulating portion supporting member 56 are supported by the upward force so as to cross over the guide rail 8, but also support the downward force.
- the retracting mechanism of the regulating portion support member 56 may be omitted.
- the restricting member 108 is a force-removable pin, and the restricting member 108 is a restricting position for preventing the rod B from moving to the swing member 66.
- a mechanism may be used in which a member capable of reciprocating between a non-restricted position that does not hinder the movement is operated by the actuator.
- the operation lever 156 is moved sideways around the second pivot 172. If the operation lever 156 can be locked by moving the operation lever 156 to the locking position by pivoting the operation lever 156, the operation lever 156 is connected to the second pivot 172 as in the second embodiment. It is not necessary to pivot to the center. For example, a member for locking the operation lever 156 at the lower position 156d may be employed.
- the first path does not necessarily have to be a linear path as in the third embodiment, and the lifting member 154 can be lifted to the lifting position 154b.
- a path for example, an oblique path or a curved path can be taken.
- the second path can take an arbitrary path as long as the operation lever 156 can be moved from the first path to the locking position 156e. Therefore, in the third embodiment, the first path and the second path are all J-shaped, but may be L-shaped, for example. Further, as long as the operation lever 156 can move along the first path and the second path, the shapes of the notches 180a and 180b of the side wall 160 are arbitrary.
- the retreat position 154a of the lifting member 154 is described as being lower than the inner bottom surface 30b of the guide rail 30, but may be flush with the inner bottom surface 30b.
- the bar B is removed by moving the bar regulating member 54 and the regulating portion supporting member 56, but the bar B in the guide rail is removed by using the bar lifting devices 100 and 150. If the bar B can be lifted and then removed, the bar B can be removed without moving the bar regulating member 54 and the regulation portion supporting member 56.
