Next, the operation of the boxing device 2 configured as described above will be described. First, when the device 2 is started, the stopper 25 of the introduction conveyor 4 is projected from the carrier side, the roller 32 of the delivery conveyor 35 is constantly rotated, and the charging device 55 has the crank pin 114 of the crank mechanism 110 upward. At the dead point, the device 55 faces the delivery conveyor 35 at a predetermined angle with the shaft pin 104 of the support member 100 as the center, and the adsorption chambers 7 on the left and right sides are exposed.
The blower 93 connected to the No. 1 suction chamber 79 is rotated.

In this state, when the first work W, which has been supplied from the work supply conveyor 1 at a predetermined interval from the previous process, is supplied to the introduction conveyor 4, this is detected by the introduction detection sensor 23, and this detection signal is detected. As a result, the servo motor 7 of the conveyor 4 is rotated, and when the work W is moved to the stopper 25 protruding to the end of the conveyor 4 and blocked, the servo motor 7 is stopped.

Then, when the next work W is supplied to the introduction conveyor 4 and detected by the introduction detection sensor 23, the stopper actuator 26 is actuated by this detection signal and the stopper 25 is retracted to allow the conveyance of the work W. At the same time, the servo motor 7 is rotated and the two works W are inherited by the delivery carrier 30 which is rotated at the same speed as the introduction conveyor 4, and is blocked by the stopper member 43 provided at the end of the delivery conveyor 30. At the same time, it is detected by the arrival detection sensor 45.

The crank drive motor 111 of the crank mechanism 110 is rotated by the detection signal of the arrival detection sensor 45, and the disc 113 attached to the rotary shaft 112 is rotated so that the insertion device 55 moves the shaft pin 104 of the support member 100. While descending as a center, the crank pins 114 are adsorbed by the adsorption holes 91 of the adsorption belt 90 mounted on the left and right adsorption chamber mechanisms 70 facing the two works W on the transfer conveyor 30. When the top dead center is reached, the drive motor 111 is stopped, and when the crank pin 114 reaches bottom dead center, the drive servo motor 63 is activated and the suction belt 90 is rotated, so that the two workpieces W are held by suction. It is then transported in the right angle direction.

When a predetermined pitch movement is given to the suction hole group 91 by the predetermined rotation of the driving servomotor 63, the motor 63 is stopped and the two works W are dropped.
Adsorbed and held on. In the process of sucking and moving the work W, the blower 93, 94 is rotated in the normal suction chamber 79 and the suction chamber 80 of the suction chamber 71 to be in the suction state.

When stopped above the outlet 51, the suction chamber 8 is driven by the transfer completion signal of the driving servomotor 63 and the detection signal of the boxing position arrival detection sensor 124.
0 suction is stopped and each adsorption chamber 71
The loading cylinders 121 provided on both sides of the
The work W is dropped into the packaging box H which is opened from the opening 51 and is on standby. After that, the above operation is repeated to sequentially perform box filling.

As described above, according to the boxing apparatus 2 of the present embodiment, the work W is aligned by the suction chamber mechanism 70 in which the rotary suction belt 90 is hooked on the charging apparatus 55 arranged at a right angle to the supply conveyor 3. Since it is possible to carry out the box packing processing continuously while adsorbing and holding the wafers, it is possible to carry out the box packing processing by coping with the work W conveyed at a high speed.

Further, the suction belt 90 is intermittently driven by the driving servomotor 63 to give a predetermined movement pitch to the suction holes 91 group and stop at the suction position and the loading position, so that a reliable work can be performed. It becomes possible to adsorb W and put it in the packaging box.

Even if the work W may drop downward from the suction belt 90 due to a suction error, it is dropped because the projection 92 is provided at a predetermined position on the rear side of the rotation of the suction holes 91. The work W can be forcibly pushed to the box packing position by the projection 92 and put into the packaging box H.

In the above embodiment, the adsorption chamber 71 is divided into a normal suction chamber 79 and a suction chamber 80 to constantly suction the normal suction chamber 79, and the suction chamber 80 turns adsorption on and off. However, the present invention is not limited to this. For example, both chambers 79 and 80 may be set so as to always perform a suction operation, and may be charged by the charging cylinder 121.
In this case, the partition wall 78 may be omitted.

Further, although the operation of the charging cylinder 121 is exemplified to be operated by the transfer completion signal of the drive servomotor 63 and the detection signal of the box packing position arrival detection sensor 124, the present invention is not limited to this. The position detection sensor 124 is omitted and the drive servomotor 63 is omitted.
The transfer cylinder completion signal, that is, the rotation stop signal of the rotation control pulse, may operate the closing cylinder 121.

[0035]

As described above, according to the present invention, the arrangement state of the workpieces is held by suction by the suction chamber mechanism in which the rotary suction belt is hooked on the feeding device disposed at a right angle to the supply conveyor. Since it is possible to carry out the box packing process continuously under such conditions, it becomes possible to carry out the box packing process by coping with the works W conveyed at high speed. Further, the suction belt is configured to be intermittently driven by the driving servomotor to give a predetermined movement pitch to the suction hole group and stop at the suction position and the loading position, so that the suction of the workpiece and the packaging box can be surely performed. Can be input. Further, even if the work W may drop downward from the suction belt due to a suction mistake, a protrusion is provided at a predetermined position on the rear side of the rotation of the suction hole group, so that the dropped work is forced to this protrusion. It can be pushed to the box packing position and put into the packaging box.
