As a result, the nut plate 6d to which the screw rod 7 is screwed, that is, the flat plate portion 6a is lifted against its elasticity, and the lower edge 6e of the sliding cutting plate portion 6b and the upper surface of the sliding surface portion 2a of the sliding plate 2 are moved upward. The size of this gap can be adjusted as the gap becomes wider.

FIGS. 6 and 7 show a second embodiment.
Members having the same functions as those in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted.

The screw aligner / supplier in this embodiment has a rectangular frame shape in plan view, similar to the first embodiment, and has a base frame 1 in which both upper sides in the longitudinal direction are inclined in one direction. A sliding plate 2 disposed in parallel with the inclined upper side 1 a of the base frame 1, a stopper 3 for a screw S disposed below the sliding plate 2, and a position substantially directly above the stopper 3. A guide plate 4 of the magnet driver D is provided, and a sliding body 5 and a correction plate 6 are provided in the middle on the inclined upper side 1a of the base frame 1.

In the guide plate 4 of the magnet driver D in this embodiment, both sides of the mounting piece 4a are formed in a hat shape when viewed from the end, and each horizontal leg piece 4f following the upright piece 4e is formed by a hat. The sliding member 5 is fixed on the slide plate 2, and the outside of the both side plate portions 5 b is formed on both side walls 1 b of the base frame 1.
Each of the side plates 5b of the sliding body 5 is formed so as to be in contact with the inside of the
The protrusion 5c formed on the outside of the slidably fits.

Further, the sliding member 5 is provided with a moving operation piece 8. The moving operation piece 8 has a U-shape in a plan view (FIG. 7), and has mounting pieces 8 provided at both open end portions thereof.
a and an operation piece 8 having an insertion hole 8c for the driver D
The mounting piece 8a is attached to each side plate 5b of the sliding body 5 with the operation piece 8b directed downward and inclined, so that the base frame 1 is bridged between both inclined upper sides 1a. Will be arranged.

FIG. 8 shows another embodiment of the straightening plate attached to the sliding body in the screw aligning and feeding device.
Members having the same functions as those of the above-described embodiments are denoted by the same reference numerals, and redundant description will be omitted.

The correction plate 6 includes a flat plate portion 6a, a sliding plate portion 6b following the flat plate portion 6a, a nut plate 6d and a screw rod 7 screwed to the nut plate 6d.
Same as the correction plate 6 in (2), except that the sliding plate portion 6
b is provided with a scooping piece 6f.

The scooping piece 6f has an L-shape as viewed from the end face by a vertical piece 6g and a horizontal piece 6h.
h is brought into contact with the lower edge 6e of the sliding plate portion 6b.
g is applied to the surface of the sliding plate 6b in the downwardly inclined direction and screwed so that the tip side of the horizontal piece 6h is directed upward in the inclined direction. The portion 6a, the sliding piece 6b, and the horizontal piece 6h of the scooping piece 6f are formed in a hook shape in end view.

The screw aligner / supplier in the above-described embodiment turns the knob 7a of the screw rod 7 provided on the straightening plate 6 to lower the lower edge 6e of the sliding plate 6b and the sliding plate 2 of the base frame 1. After adjusting the gap size with the upper surface to a size that allows the head of the screw S to pass through, a large number of screws S are thrown into an upper position on the inclined slide plate 2.

A large number of the screws S are dropped on the slide plate 2 by their own weight, and the shafts of the screws S inserted into the guide slots 2d are guided by the guide slots 2d. The lower edge 6 of the straightening plate portion 6b of the previously adjusted straightening plate 6 while descending in a state of being aligned.
The screw S having an abnormal posture, such as a roll screw, passes through the gap e and is blocked by the sliding plate 6b.

The screw S blocked by the sliding plate 6b
May be moved to the upper position along the guide groove 1d of the base frame 1 by gripping the sliding body 5, or into the insertion hole 8c provided in the operation piece 8b of the moving operation piece 8 in the second embodiment. An operation such as inserting the driver D and flipping up the sliding body 5 in an inclined upward direction is pushed up to an upper position on the slide down plate 2 by the sliding plate 6b, and the sliding body 5 is returned to the original position, When the screw S is dropped by its own weight, the screw S falls on the slide plate 2 again. With this operation, both ends of the projecting piece 5c of the sliding body 5 are hit against both ends of the guide groove 1d, thereby forming the base frame body. 1, that is, the whole including the slide plate 2 is vibrated. By repeating this operation, the position of the screw S is gradually corrected by dropping on the slide plate 2 while being subjected to vibration, and the shaft of the screw S is inserted into the guide slot 2 of the slide plate 2.
d, and falls downward while being aligned while passing through the gap between the sliding plate portions 6b of the correction plate 6, and the head of the screw S contacts the tongue piece 3c of the stopper 3 disposed at the lower position. Stop falling by touching.

In the repetitive movement operation of the sliding body 5 provided with the correction plate 6 in the embodiment shown in FIG. 8, when the sliding body 5 is moved to the upper position, the horizontal screw as shown in FIG. The screw is scooped up by the horizontal piece 6h and carried to the upper position, and the screw that has been scooped up gradually falls down from the horizontal piece 6h due to the subsequent downward movement of the sliding body 5 and the above-mentioned vibration action. The shaft of the screw S easily enters each guide slot 2d of the slide plate 2.

The operation of taking out the leading screw S which is aligned with each guide slot 2d of the sliding plate 2 and stopped by the stopper 3 is performed by moving the tip of the magnet driver D along the guide step 4b of the leading guide plate 4. Any notch recess 4
d, and inserted into the head groove of the screw S through the notch recess 3d provided in the tongue piece 3c of the stopper 3, and in this state, the driver D is pulled in the direction of the slot 2e of the slide down plate 2. The tongue piece 3c of the stopper 3 is pulled up against its elasticity, and the screw S is taken out in a state of being attracted to the tip of the driver D. The subsequent screw S is formed by the tongue piece 3c of the stopper 3 By returning to the original state from the state of being lifted at the time of removal, the head is pressed down and the fall is stopped.

The screw aligner / supplier in this embodiment is provided with a simple feeding means for feeding a large number of screws to a position above the slide plate, and by repeatedly moving the sliding body up and down along the slope, thereby providing vibration. In addition to taking the means for correcting the posture of the screw, the screw is aligned with each of the plurality of guide slots provided in the slide plate, and the screw can be taken out from each guide slot. The guide plate at the tip of the driver during the work is provided with a guide step, which allows the driver to move along the guide step and insert the tip into one of the cutout recesses provided above each guide slot. Although it is not necessary and has a simple configuration, it can sufficiently exhibit the same ability as a conventional machine of this type, can reduce the equipment cost, is simple in operation, and has good workability.
