At this time, the vacuum suction pipe is preferably configured to be connected to each of the suction head 85 is branched from each of the one main suction pipe.

It is preferable that the drive part 91 which operates the head part comprised in this way is comprised so that the drive which rotates the head part 71 together with the drive which moves forward and backward of the said head part 71 can be performed simultaneously.

At this time, the drive for advancing and reversing the head portion 71 is advanced to take out the port 10 from the port stacking portion 50, and then suctions the port 10, and then moves backward to port each port 10. It is for separating from the stack 10A or advancing the sucked port 10 into the tray 20 and then backing the port 10 into the tray 20 and then back.

In the driving for rotating the head portion 71, the head portion 71 is rotated by 90 degrees in a state in which the head portion 71 is positioned in parallel with the port loading portion 50 (horizontal state in the drawing), and the head portion 71 rotates in the tray ( 20) so that it is located in the direction perpendicular to the.

For these two types of driving, the drive unit 91 is configured to be operated using two rotary motors 93 and two forward and backward motors 96. To this end, support brackets 94 are provided on both sides of the apparatus frame 30 as shown in the drawing, and the main rotation shaft 92 is rotatably supported on both support brackets 94.

Referring to the operation of the soft-pot filling device for filling the soil according to the present invention configured as described above are as follows.

8 to 14 are views showing the process of taking out the port 10 and storing it in the tray 20 using the apparatus according to the present invention.

It demonstrates with reference to these drawings.

First, FIG. 8 is a view showing a standby state before taking out the port 10. After the tray 20 is transferred to the lower side of the port take-out unit 70 by the transfer conveyor of the tray transfer unit 40, the tray is sensed. As the entry of the tray 20 is detected by the sensor 47, it shows the state when the conveyor belt 41 is stopped.

In addition, the port stacking unit 50 is in a state in which the port stacks 10A are stacked in four rows. At this time, while the vibrating mechanism 52 is operated, the ports 10 are moved toward the port ejection unit 70. Will be in.

In addition, the port take-out and input part 70 is positioned in a horizontal state, which is a position before the head portion 71 takes out the port 10, and is in the reverse state as a whole.

Next, in the standby state as described above, as the forward and backward motors 96 are operated as shown in FIG. 9, the crank shaft rotates while the crank pin 100 is rotated 180 degrees to move forward as the connecting rod ( 101 and the head base 73 connected thereto is advanced.

At this time, the pair of suction heads 85 are also advanced and positioned inside each port 10, and in this state, a pair of head operation bars 75 are provided with pneumatic pressure to the head actuator 80. It moves in the opposite direction, and by this movement, each pair of suction heads 85 are brought into close contact with the inner surface of each port 10. At the same time, each suction head 85 is provided with a vacuum pressure while the port 10 is sucked into each suction head 85 to be in an attached state.

Next, with each pair of suction heads 85 sucking each port 10, when the forward and backward motor 96 is operated again as shown in FIG. 10, the crankshaft rotates and the crank pin 100 is rotated. It rotates 180 degrees and moves backwards, and thus, the connecting rod 101, the head base 73 connected thereto, and the suction head 85 are reversed to separate one port 10 from the port stack 10A. Do it.

Here, the reason why only one port 10 is separated from each port stack 10A is because the stopper brush 64 provided in the port stacking portion 50 blocks the front of the port stack 10A. Only one port 10 adsorbed to the suction head 85 is taken out, and the remaining ports 10 are caught in the brush and are in a restricted state.

In addition, a fork-type guide 65 having a fork-shaped structure is installed on the upper side of each port stack 10A in the mounting table 61, and a stopper brush 64 is installed on the lower side of the port 10. It is possible to minimize the problem of more than one extraction. This makes it possible to increase the reliability of the port 10 ejection operation by pressing the ports 10 at the top and preventing the other ports 10 from being ejected along the port 10 from which the port 10 is ejected when the port 10 is ejected at the bottom. do.

Next, when the rotary motor 93 rotates 90 degrees in the state where the port 10 is taken out through the port take-out input unit 70 as described above, as shown in FIG. 11, the main rotary shaft 92 At the same time as this rotation, the head portion 71 is also rotated by 90 degrees while the head portion 71 is positioned in the vertical state.

Next, when the forward and backward motor 96 is operated in the state in which the ports 10 are positioned on the upper portion of the tray 20 as described above, as shown in FIG. 12, the crank pins are rotated according to the rotation of the crankshaft. As the 100 is rotated 180 degrees downward, and the connecting rod, the head base 73, and the suction head 85 are moved vertically downward, the respective ports 10 are inserted into the respective insertion portions 21 of the tray 20. Is put into.

Then, by releasing the vacuum pressure provided to each of the suction heads 85 and removing or vice versa the pneumatic pressure provided to the actuators, the pair of transfer bars 56 are moved in the direction in which the pair of suction heads are narrowed. Ports 10 sucked into the pair of suction heads 85 are separated from the suction heads 85 and completely introduced into the tray 20.

Next, when the input of the ports 10 to the tray 20 is completed as described above, the forward and backward motor 96 is operated again to rotate the crankshaft, and as shown in FIG. 13, the crank pin ( 100 is rotated 180 degrees upward, and the connecting rod 101, the head base 73, and the suction head 85 are vertically moved upward.

Next, when the rotary motor 93 is operated, the head portion 71 is in the standby state while being positioned in the horizontal direction, as shown in FIG. 14 in the vertical direction.

When the feed motor 45 of the tray feeder 40 is operated, the tray 20 moves forward as the conveyor belt 41 moves forward, and the tray sensor 47 moves into the insert 21 of the next row. Sensing that the port has reached the port insertion position stops the movement of the conveyor belt 41 and is in a standby state where the ports 10 can be inserted.

As the above operation is continuously repeated, the operation of automatically inputting the ports 10 to the tray 20 continuously is performed.
