[Examples] Hereinafter, the configuration and operating state of the present invention will be described in detail with reference to the drawings. The overall apparatus of the present invention is schematically configured as shown in FIGS. 1 to 3, and one side is provided with a belt conveyor 1 for continuously transferring the box B, and one side thereof is provided with the belt conveyor 1. A motor 1a is installed to drive the motor.

On the base A arranged at the rear end of the belt conveyor 1, a product transfer tool 10 for transferring the box B from the belt conveyor 1 to the grip fastening insertion grid 30 and a grip 40 'to the box B are coupled. Grip grip fastening insertion grid 30 (Fig. 5),
And wooden jig 20 such that the attached box B is unloaded by pull out from the grip gold fastening insert grating 30 of grip gold 40 'is arranged. This product transfer tool 10 is a belt conveyor 1.
Located in the right above the terminal, it can be moved up and down by an air cylinder 11, also disposed so as to be movable to the right and left by being guided by the horizontal shaft 12 by another air cylinder 11a, the product transfer tool 10 To hold Box B in
Fastening pin 10 'is provided of. This fastening pin 1
0'is a product transfer formed in a plate shape in this embodiment.
With the cylinder device arranged on the lower surface of the tool 10,
A bar-shaped member that presses and holds the inner surface of the box B is used.
However, the box B, which is the object to be transferred, is attached to and detached from the product transfer tool 10.
If it can be fixed in place, you can use other structures.
Can be

The grip grip fastening and inserting grid 30 is attached to the lower central portion of the base A, and a grip grip aligning plate 40 for supplying grip grips 40 'is installed on the base as shown in FIG. As shown in FIG. 5, a retainer 31a for retaining the grip 40 'is fixed to both sides so as to be moved forward and backward by the air cylinder 31. In addition,
The presser foot 31a is provided with four levers 32 'and 33' for bending the grip 40 'on both sides in a right angle direction. The four levers 32' and 33 'are air cylinders 32 and 33, respectively. Operated by. An air cylinder 34 for lifting the box to which the grip 40 'is fastened is provided just below the grip fastening and inserting grid 30.
Is installed.

At the top of the base, a wooden jig 20 is installed on a horizontal shaft 22 on the upper side so that the wooden jig 20 can move in line with the moving direction of the product transfer tool 10. -It is moved left and right along the horizontal axis 22 by the cylinder 22a, and is moved up and down by another air cylinder 21.
The wooden jig 20 is movable, and is provided with a fastening pin 20 'that firmly supports the box B. In addition, this fastening pin
20 'engages with the outer surface of box B, and
If it is configured to project or retract by a
Is most preferable, but engages with protrusions or recesses on the surface of Box B
A fixed one can also be used.

As shown in FIG. 9, a roller conveyor 3 for discharging the box B and a piston 4 for pushing out the box B are provided at the lowermost end on the back side of the base A. The device of the present invention constructed as described above operates as follows. When a box B injection-molded by an injection molding machine (not shown) is placed on the belt conveyor 1 and reaches the end portion of the belt, an optical sensor detects the situation, and a control circuit for controlling the entire machinery is operated by the belt conveyor 1. Stop motion and prevent box B from moving any further. The position of the box B at this time is located directly below the product transfer tool 10.

At this moment, the operation of the sensing limit switch causes the control circuit to operate the air cylinder 11 which raises and lowers the product transfer tool 10 to lower the product transfer tool 10. When the product transfer tool 10 descends and contacts the upper part of the box B, the fastening pin 10 'of the product transfer tool 10 fastens the upper end of the box B, and the air cylinder 11 supplies the air. The direction is changed and the product transfer tool 10 is raised.

At the moment when the lifting of the product transfer tool 10 is completed, the product transfer tool 10 covered by the box B moves to the right along the horizontal axis 12 by the operation of the air cylinder 22a, and the clasp fastening is inserted. Go to the top of the grid 30 (Fig. 5), where the fastening pin 1
0'is released, and the covered box B is dropped inside the grip fastening insert grid 30. The product transfer tool 10 that has dropped the covered box B further moves to the original position along the horizontal axis 12 as shown by the chain line in FIG. 6, and at the rear of the power supply box 2 (FIG. 1) on the right front side. The wooden jig 20 that was located at
The cylinder 22a moves to move to the upper position of the right hand grip fastening insertion grid 30 along the upper horizontal axis 22.

On the other hand, as shown in FIGS. 4 and 5, when the box B to be dropped is inserted into the inside of the clasp fastening insertion grid 30,
Grips 40 'are movably supported on the gripping plate aligning plate 40 diagonally in a row at the front and rear upper parts of the gripping plate inserting and inserting grid 30, and are arranged in the middle of the lower end of the gripping plate aligning plate 40. When the grips 40 'are dropped one by one as shown in FIG. 11 by the detection signal of the optical sensor 41 and reach the fastening position along the guide path 43 of the guide protrusion 42 (FIG. 4), the grips 40', (A), ( As shown in B), the air cylinder 31 moves forward, and the fixed base 31a moves to the grip 4
At the same time as pressing 0 ', the other air cylinders 32, 33 installed on the left and right actuate the levers 32', 33 'in forward movement,
Bend both ends of the grip plate 40 'inward and insert it into the binding holes on both sides of the upper end of the box B to bind (fix) the grip plate 40' to the box B.
To do.

At this time, an optical sensor 44 is installed at the center of the bundling position, which is the end of the handgrip guide path 43, as shown in FIG. 10, and the handgrip 40 'is raised in the box B without being bound. Is detected that the grip 40 'remains in the fastening position, and the buzzer sounds to notify the defect. In this way, grips 40 'on both sides of the upper edge of Box B
When is fixed, an air cylinder 34 in the lower center inside the clasp fastening insertion grid 30 raises the box B inside the clasp fastening insertion grid 30 to the upper part of the insertion lattice 30 and at the same time. The wooden jig 20 located is
While being lowered by the cylinder 21, it is pushed into the ascending box B, and the upper end of the box is sandwiched by the fastening pins 20 'on the left and right of the upper plate 20a, then raised by the air cylinder 21, and then the upper horizontal shaft 22. Follow to move to the right.

By repeating the above operation, it is possible to cover the lower part of the wooden jig 20 with the box B and to stack a plurality of them on top of each other. This repeated operation is adjusted by the switch and easy to package. When 5 pieces are overlapped, the wooden jig 20 descends from the left side by the air cylinder 21 as shown in FIG. 9, and the fastened pin 20 'is attached to the upper part of the roller conveyor 3 which is slightly inclined to the right. Separated from Box B,
While the loosening piston 23 projects downward from the center of the bottom of the wooden jig 20 (FIG. 4), a plurality of stacked boxes B are separated from the wooden jig 20 and placed on the roller conveyor 3. . At this time, the pistons 4 are projected rightward from the upper left side of the roller conveyor 3 to form a plurality of stacked boxes B.
To the right.
