Here, three second chucks 49 are attached at intervals.

A box supporting mechanism 41, which is installed obliquely below the second chuck mechanism 40 so as to face the second chuck mechanism 40, continuously supplies empty boxes 52 to the side thereof as shown in FIG. 53 are provided. The box support mechanism 41 is shown in FIG.
As shown in FIG. 7, a roller conveyor 56 is mounted on a support frame 54 via a hinge 55, and the tip of a tilting cylinder 57 mounted on the side surface of the support frame 54 is connected to the bottom of the roller conveyor 56. 56 is tiltably supported.

A cylinder 58 is attached to the side of the frame of the roller conveyor 56.
9 is connected so that it can move forward and backward freely. As shown in FIG. 6, three box chucks 60 are provided inside the support frame 59 to hold the empty box 52 conveyed on the roller conveyor 56. Further, guide shafts 61, 61 are protrudingly provided below the support frame 59 so as to penetrate and guide the frame side surface of the roller conveyor 56.

In the automatic nail packing apparatus having the above construction, first, a plurality of nails 1 are arranged in parallel at intervals as shown in FIG. 8, and a stick 3 in which these intermediate parts are integrally connected by a plastic 2 is not shown. It is supplied from a supply device to the supply conveyor 4 shown in FIG. 1, and the sticks 3 are alternately turned upside down so that the tips face each other, and are conveyed in two rows by the sorting machine 10 provided here. In front of the supply conveyor 4, a belt conveyor 5a and a belt conveyor 5b are arranged in parallel, and one row of the sticks 3 shifts to the belt conveyor 5a whose tip is inclined upward, and the other row of the sticks 3 Is transferred to and conveyed on a belt conveyor 5b provided horizontally.

The sticks 3 conveyed on the roller conveyors 6a and 6b are sequentially lifted and stopped by stoppers 9 of a vertical slide type, and are stopped above the stick receiving shafts 24 of the pushing mechanism 7. Thereafter, the horizontal cylinder 22 of the pushing mechanism 7 extends as shown in FIG.
The stick receiving shafts 24 connected to the tips extend above the roller conveyor 6b and stop as indicated by the imaginary lines.

On the other hand, after the movable base 13 is lowered by the contraction of the upper and lower cylinders 14, the horizontal cylinder 17 attached to the bracket 16 is extended, and the pushing blade 18 connected to the tip of the horizontal cylinder 17 is connected to the stick on the roller conveyor 6a. 3 is pushed out and dropped onto the stick receiving shafts 24.

Thereafter, when the horizontal cylinder 22 contracts and the stick receiving shafts 24 retreat, the stick 3 whose head 1a is supported by the pushing blade 18 is
As shown in FIG. 4, two sticks 3, 3 are dropped on the riding stick 3 on the roller conveyor 6b.
Are superimposed. Thereafter, the upper and lower cylinders 14 extend as shown in FIG.
Then, the horizontal cylinder 17 contracts and the pushing blade 18 returns, and the vertical cylinder 14 contracts further and the pushing blade 18 returns to the original position and waits.

Next, the cylinder 3 of the first chuck mechanism 8
7 extend and the first chuck 36 becomes the roller conveyor 6b.
Hold the sticks 3, 3 overlying the. Next, when the rotary actuator 29 shown in FIG. 1 rotates, the first base 33 connected to the shaft 31 and the second base 33 are rotated.
The base 34 and the first chuck 36 are tilted by 45 degrees as shown by phantom lines in FIG.

At this time, the second chuck 49 of the second chuck mechanism 40 is inclined downward by 45 degrees, and the first-stage cylinder 44 extends to move the second chuck 49 obliquely downward. Then, the sticks 3, 3 held by the first chuck 36 are held and delivered. Thereafter, the first chuck 36 is released and returns to the original horizontal state. Thereafter, the arm 4 of the second chuck mechanism 40
2 is moved obliquely by the moving mechanism 39 and stops at a position facing the box supporting mechanism 41.

On the other hand, as shown in FIG. 6, the box supporting mechanism 41 is supplied with empty boxes 52 from an empty box supply mechanism 53 to a roller conveyor 56 which is continuously held horizontally. The claws of the box chucks 60 are located on both sides of the empty box 52. Thereafter, the box chucks 60 are operated to simultaneously hold the three empty boxes 52. After that, as shown in FIG.
7 is extended, the roller conveyor 56 is inclined by 45 degrees, and stands by.

In a state where the empty box 52 thus formed is inclined and stands by, the sticks 3 held by the second chuck 49 of the second chuck mechanism 40 move, and the two-stage The eye cylinder 46 extends, and the sticks 3, 3 held here are inserted into the inclined lower side inside the empty box 52, where the chuck is released and the sticks 3 are stored.

Thereafter, after the second chuck 49 has retreated, the second chuck 49 descends along the moving mechanism 39 and receives the sticks 3 held by the first chuck 36 again. Are inserted into the empty box 52 and stacked. When the box 52 is full, the tilting cylinder 57 of the box support mechanism 41 is contracted to
Back to horizontal. After that, release the box chucks 60 ...
The box 52 packed with the sticks 3 is sent to the next step, where the weight is weighed and the appropriate package is sealed with tape.

[0024]

As described above, claim 1 according to the present invention.
According to the automatic nail packing device described above, the sticks in which the heads of the nails are staggered up and down are held and moved by the chuck mechanism, and are sequentially inserted into the box held obliquely. Since the sticks can be automatically packed in the box without falling down inside the box, workability can be greatly improved.

According to the nail automatic packing apparatus of the second aspect, the push-out mechanism for stacking the sticks conveyed in parallel on the conveyor is provided on the stick receiver supported so as to be able to move back and forth, and above the stick receiver. Since it is constituted by the pushing blade supported to be able to move forward and backward freely, the work of stacking the sticks can be automated. According to the automatic nail packing device of the third aspect, the box supporting mechanism for tilting and supporting the box is formed so as to be tiltable, so that the box is held horizontally when loading and unloading the box, and only when the stick is packed in the box. Since the box is held inclined, it is possible to prevent the stick from falling down during the packing operation.
