The leaf springs 81, 82, 83, 84 are in close contact with at least one sheet in consideration of elastic force, and may be formed in close contact with two to ten sheets when the thickness becomes thin for smooth elasticity.

The protrusions 28 formed on the bottom surface of the bottom plate 16 of the support members 91, 92, 93, and 94 and the protrusions 28 formed on the upper surface of the block 95 are coupled to each other. It further comprises a guide groove (29). The protrusions 28 and the guide grooves 29 are formed long in the direction in which the gap d can be adjusted, and the length of the guide grooves 29 is formed longer than the length of the protrusions 28 so that the nails 2 feed. The necessary gap d can be achieved.

That is, Figure 5 illustrates a state adjusted to the optimum gap (d), when the diameter, length or weight of the nail (2) is changed, the gap (d) is adjusted to obtain the optimum vibration, such In this case, the fastening member 19 holding the bottom plate 16 is relaxed, and then the knob 24 of the clearance adjusting hole 15 is rotated clockwise (or counterclockwise) to support members 91 and 92. (93) (94) is moved to adjust the oscillator and stator gap (d) appropriately, and then tighten the loosening fastening member (19) to adjust the gap (d). 8 is a state in which the gap d3 is widened by moving the supporting members 91, 92, 93, 94 in the opposite directions of the vibrators 77, 78, 79, 80. An illustration of the.

When the support members 91, 92, 93, 94 are moved in the above, the protrusions 28 formed on the bottom surface of the bottom plate 16 of the support members 91, 92, 93, 94 are blocks ( Since it moves in the longitudinal direction along the guide groove 29 formed on the upper surface of the 95, the twisting of the support members 91, 92, 93, 94 is prevented, and thus the vibrators 77, 78, 79 ) 80 and the stator (87) (88) (89) (90) is faced to the same side because a uniform magnetic field is applied and a uniform and smooth vibration is generated.

The block 95 further includes a case 30 installed in all directions.

The case 30 is configured such that the upper ball 5 is not in contact with each other so as not to interfere with or affect the vibration of the ball 5. The lower portion of the case 30 is fixed to the side of the block 95 by a plurality of fastening members.

The ball 5 and the ring member 6 may be fastened and fixed to the vibration member 7 by fastening members 31 such as screws, bolts, countersunk bolts, and the like.

The ball 5 may be directly fixed to the vibrating member 7, in which case the configuration of the ring member 6 is omitted.

In the present invention, the fixing members 96, 97, 98 and 99 which are installed as fastening members 34 on the bottom surfaces of the supporting members 91, 92, 93 and 94 can also be configured to be movable. have. That is, a short projection 32 is formed on the bottom surface of the block 95, and the projection 32 is coupled to the upper surfaces of the fixing members 96, 97, 98, and 99 to slide. The guide springs 33 having a length longer than the protrusions 32 are formed to move the fixing members 96, 97, 98, and 99 so as to move the leaf springs 81, 82, 83, and 84. The gap d is formed by moving the positions of the vibrators 71, 72, 73, 74 and the vibrators 77, 78, 79, and 80 fixed to the upper end 85. I can regulate it.

In the above, when the fixing members 96, 97, 98, 99 also move, the protrusions 32 formed on the bottom surface of the block 95 have the upper surfaces of the fixing members 96, 97, 98, 99. Since it moves in the longitudinal direction along the guide groove 33 formed in the fixing member 96, 97, 98, 99 is prevented from twisting.

On the other hand, when an alternating power source, pulse power source, or low frequency power source is applied to the excitation coils 871, 881, 891, and 901 of the stators 87, 88, 89, and 90, an excitation coil that generates an alternating magnetic field ( The vibrators 77, 78, 79, 80 vibrate by the 871, 881, 891, 901 and the core, and move away from or close to the stators 87, 88, 89, 90. .

FIG. 6 is a state where the vibrators 77, 78, 79 and 80 are as close as possible to the stators 87, 88, 89 and 90 due to vibration, and a narrow gap d1 is formed. As the vibrator 77, 78, 79, 80 is as far away from the stator 87, 88, 89, 90 as the vibration is formed, a wide gap d2 is formed. Since the ball 5 is rotated forward and / or reversed (D direction) about the central axis C, rotational motion and / or rotational and vibrational motion are generated, and thus the nail 5 is not irregularly positioned in the storage chamber 3. (2) moves along the spiral ramp 4a, enters the alignment line 4 formed on the ramp 4a, is aligned, and is discharged in the discharge direction (F direction).

In the present invention, when the vibrators 77, 78, 79, 80 vibrate between the vibrators 77, 78, 79, 80 and the stators 87, 88, 89, 90 As shown in Fig. 6, a minimum gap d1 is formed so that the vibrators 77, 78, 79, 80 and the stators 87, 88, 89, and 90 do not come into contact with each other, thereby causing a collision and the resulting noise. This does not occur, and no shock vibrations vibrating the vibrators 77, 78, 79, 80 and the ball 5 also occur.

The left and right ramp 4a is connected by the connector 101 while maintaining an alignment line 4 through which the alignment nail 2 can pass.

According to the present invention, the gap adjusting device 15 can be used to precisely achieve an appropriate or optimal gap (d) to obtain an optimal vibration, and also the size and / or the outer diameter and / or the weight of the nail 2 By varying the gap d, optimum vibrations, ie, alignment and transfer and discharge, can be achieved.

The present invention is provided with four vibrators 77, 78, 79, 80 and four stators 87, 88, 89, 90 and four leaf springs 81, 82 installed in all directions. Since the ball 5 is smoothly and stably operated and vibrated by vibrating means composed of 83, 84, etc., the nails of the storage compartment 3 are arranged and discharged smoothly, and the shock vibration is vibrated by the four vibrating means. However, as the large vibration is canceled, there is an effect that the nails 2 are smoothly discharged with stable vibration.

The present invention not only improves nail manufacturing or handrail productivity by the ball feeder 1 of stable operation, but also minimizes noise generated when the ball feeder 1 operates because there is almost no up and down vibration, and shock vibration or shaking This has the effect of being prevented.

According to the present invention, when the diameter, length, weight (weight), etc. of the target nails 2 are changed, the optimum vibration can be obtained by adjusting the gap d using the gap adjusting tool 15.

According to the present invention, the support members 91, 92, 93, and 94 moving when adjusting the gap d are formed on the bottom plate 16 of the support members 91, 92, 93, and 94. Since the 28 moves in the longitudinal direction along the guide groove 29 formed in the upper surface of the block 95, the twisting of the support members 91, 92, 93, 94 is prevented, and thus the vibrator 77 (78) (79) 80 and stator (87) 88 (89) (90) are facing each other in the same plane, so there is an advantage that uniform magnetic field is applied and uniform and smooth vibration is generated.

The present invention described above is not limited to the present embodiment and the accompanying drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention, and this is in the technical field to which the present invention belongs.
