DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a material supply device,
Is provided with a plurality of rotatable feed rollers 3 for feeding the material W in the longitudinal direction thereof. Shelf 5
It is installed stepwise in the vertical direction, and is kicked by the kick-out device 7 from the material sending end side of each inclined shelf 5 between the material sending end side (left side in FIG. 1) of the inclined shelf 5 and the material feeding roller 3. An elevating device 9 for temporarily lifting the delivered material W and feeding the material W to the material feeding roller 3 is provided.

A stopper 11 for preventing the material W from spontaneously moving out from the material delivery end side of the inclined shelf 5 is provided on the material delivery end side.
Is provided.

[0009] The illustrated kick-out device 7 is, for example, a material W
Kicking arm 15, which is installed at a position near the center in the longitudinal direction of the arm, and is pivotally supported on the inclined shelf 5 by the support shaft 13.
And a cylinder 21 having one end of the kicking arm 15 connected to the piston rod 19 by a pin 17. The cylinder 21 is pivotally supported by the pin 23 to be able to swing to the inclined shelf 5. I have.

The kick-out arm 15 is moved from a retracted position where it does not protrude from the upper surface of the inclined shelf 5 as shown in an enlarged view in FIG.
As shown in FIG. 3, it is rotated by the operation of the piston rod 19 until it reaches the projecting position projecting upward from the stopper 11, and when projecting from the retracted position, the stopper 11 has been used as shown in FIG. The foremost material W on the outflow side of the material W, which has been prevented from moving out, is moved over the stopper 11 and is transferred into the elevating device 9, and the next material W is removed.
Is formed in a shape having an arc-shaped portion capable of appropriately restricting transfer into the stopper 11 side so as to separate the material W that has climbed over.

In the case of the material W ₁ having a large cross-sectional dimension as exemplified in FIG. 4, in order to ensure separation from the next material W ₁ and regulation of transfer into the stopper 11, The kick-out amount of the kick-out arm 15 needs to be larger than that of the material W having a small cross-sectional dimension illustrated in FIG.

For this reason, the cross-sectional dimension (diameter) of the material W or W ₁ on the inclined shelf 5 is measured by a diameter measuring machine (not shown), and the material is kicked in accordance with the measured diameter of the material W or W _1. The stroke of the piston rod 19 of the cylinder 21 is controlled by a command from the control device 25 so that the kick-out amount of the arm 15 is automatically adjusted.

In the illustrated lifting device 9, a driving sprocket 27 connected to a pulse motor type driving motor (not shown), a driven sprocket 29, and a lifter 31 wound around these sprockets 27, 29 are mounted. The lifter chain 33 is used.

When the inclined shelf 5 to be supplied is designated by a push button (not shown) of the control device 25, the drive motor is driven to a position where the lifter 31 matches the material sending end side of the inclined shelf 5.

The material W transferred to the material feeding roller 3 is transferred by a material feeding device chain 35 to, for example, a cutting device (not shown).

In order to facilitate replenishment of the material W to the inclined shelves 5 arranged in multiple stages vertically, the material W is inclined from the side opposite to the material sending end side by an inward / outward movement operation along the inclined direction. A material supply table 37 for supplying materials to the shelves 5 is provided on each required inclined shelf 5.

The exemplified material supply table 37 is constituted by a supply table 41 which is movable by being guided by a guide 39, and a cylinder 45 having its piston rod 43 connected to the supply table 41 and fixed to the inclined shelf 5. When the supply table 41 is projected from the opposite side of the inclined shelf 5 from the material sending end side, the material W is transferred here by appropriate transfer means, and then the piston rod 43 is retracted. The projecting portion 47 provided at the end pushes the material W toward the inclined shelf 5, and the material W is transferred to the inclined shelf 5 so that the material W is transferred to the inclined shelf 5.
The shape such as the upper surface portion 1 is set.

The presence or absence of the frontmost material W on the sending side is determined by determining whether the material W retained by the stopper 11 is a transmission type photosensor 4.
9 is performed by the detection operation.

Next, the operation of the above configuration will be described. The kicking arm 15 of the kicking device 7 is held at a immersion position where it does not protrude from the inclined shelf 5. When the supply table 41 is made to protrude from the opposite side of the inclined shelf 5 from the material sending end side, the supply table 41 can be supplied without being hindered by the upper inclined shelf 5.
The material W can be easily transferred.

When the piston rod 43 is retracted, the convex portion 47 of the supply table 41 pushes the material W toward the inclined shelf 5, and the material W is transferred to the inclined shelf 5, and the material W is tilted. The roller W rolls on the inclined shelf 5 to lock the material W on the sending side at the stopper 11 to the stopper 11, and the photo sensor 49 detects that the material W is present on the inclined shelf 5.

When the inclined shelf 5 to be supplied is designated by a push button (not shown) of the control device 25, the drive motor is driven until the lifter 31 coincides with the material sending end side of the inclined shelf 5 (this inclined motor). When it is not detected that the material W is present on the shelf 5, the drive motor is not driven even if the above designation is made.)

When the match of the lifter 31 is detected by a limit switch (not shown) or the like, the control unit 2
5, the piston rod 19 of the kick-out device 7
, The arm 15 of the inclined shelf 5 projects from the inclined surface of the inclined shelf 5.

At the time of this protruding, as shown in FIG. 3, the foremost material W on the delivery side, which has been prevented from moving out by the stopper 11 so far, is kicked out and over the stopper 11 to be placed on the lifter 31. The next material W
Is separated by the protruding kick-out arm 15 from the material W which has climbed over, so that only the one material W at the frontmost position on the sending side moves into the lifter 31.

When the transfer operation is performed, the lifter chain 33 rotates in the direction of the arrow in FIG.
The lifter 31 rises and rides over the driven sprocket 29 to discharge the material W onto the material feeding roller 3. The material W transferred to the material feeding roller 3 driven by the material feeding device chain 35 is not shown. For example, the phase is shifted to the cutting device.

In this embodiment, the diameter of the material W on the inclined shelf 5 is measured by a diameter measuring machine (not shown), and the kicking amount of the kicking arm 15 is automatically determined according to the measured diameter of the material W. The stroke of the piston rod 19 of the cylinder 21 is controlled by a command from the control device 25 so that the material W
The operation of separating the material W on the sending side from the material W on the next side is always reliable, regardless of the diameter of the material W, and only one material W is accurately transferred to the lifter 31. have.

The kicking-out device 7, the lifting device 9, the material supply table 35, the material feeding roller 3 and the like applied to the present invention are not limited to those in the above-described embodiment, but have the same functions as those described above. However, the present invention can be applied to a variety of configurations.
