The operation of the present invention will be described below.

For the assembly tray (a), one of the two side plates (b ₁ ) on the longer side of the empty tray discharge belt of the filter plug feeder can be unfolded by the operator or the opening (a ′) can be directed downward. Further, it is placed on the supply conveyor (3) in the transfer device (B) with the side plate (b ₂ ) on the non-deployment side facing forward. Then, when the assembly tray (a) is placed on the arm (2a) of the lifter (2) by the conveyor, the arm (2a) is lifted by the operation of the cylinder (2b) and stands by above the lifter (a). It is lifted up to the vacuum cup (4a) in (4).

After that, the vacuum cup (4a) adsorbs the back plate (d) of the assembly tray (a), the lifter (2) descends, and the adsorber (4) moves along the rail (R) for conveyance. At the same time as stopping above the conveyor (1), the suction of the vacuum cup (4a) is cut off and the assembly tray (a) is dropped onto the transport conveyor (1).

At this time, when the assembly tray (a) is retained on the stopper (6) on the transfer conveyor (1) and on the way of the drop passage (c), the transfer conveyor and the drop passage linked with the adsorber (4). Overflow operation in which the adsorber (4) moves as it is without stopping on the conveyor (1) by the action of a sensor (not shown) on the way, and the assembly tray (a) is dropped at the end of the rail (R). Works.

Further, when performing the overflow operation, the traveling of the adsorber (4) is switched to the high-speed traveling to maintain the normal processing capacity, and when the cause of the overflow disappears, the normal transfer state is restored.

In this way, the assembly tray (a) dropped on the transport conveyor (1) is transported in the front ascending state, and the front side plate (b ₂ ).
When it comes off from the tip of the conveyor (1) and becomes horizontal and protrudes downward, the conveyor (1) is stopped by a sensor (not shown). At the same time, the adjustment pushers (1b) on both sides of the transfer conveyor (1) slide to the conveyor (1) side to correct the bending of the assembly tray (a) in the traveling direction and place the assembly tray (a) at the normal position, and then the fall path. Make it easy to drop (C).

Then, after the position adjustment, the transport conveyor (1) operates again, the assembly tray (a) is pushed out of the conveyor (1), and the side plate (b ₂ ) on the non-deployment side along the guide roll (10).
Is dropped and the fall path (C) is dropped and held by the holding arms (6a) (6a) of the stopper (6) on the way.

Then, the posture of the assembly tray (a) is corrected on the stopper (6), and at the same time, the tray (a) stays on the mounting portion (Q) of the assembly tray (a) below the stopper (6). If so, keep it as it is.

When the cylinder (6b) of the stopper (6) contracts, the holding arms (6a) (6a) move to the outside of the drop path (C), and the assembly tray (a) moves along the guide plate (5). (C) Drop vertically to the mounting portion (Q) at the lower end.

When the assembly tray (a) is dropped and placed vertically on the mounting portion (Q) in this way, the cylinder (17c) connected to the holding plate (17b) of the fixing mechanism (16) and the cylinder of the support tool (18) ( holding plate by the operation of 18 d) (17b) is then laid down forwardly, with holding the undeployed side plate assembly tray (a) (b _2), the back plate of the assembly tray advances fixing piece (18a) is (D) The assembly tray (a) is fixed by being brought into contact with the inside.

Further, at this time, while being supported by the back plate (d) of the vertically dropped assembly tray (a), the both side plates (c ₁ ) (c ₂ )
The guide piece (20a) that was in contact with is retracted and the guide holding is released.

When the fixing mechanism (16) fixes each surface of the assembly tray (a) in this manner, a cylinder connected to each movable member (11) of the expansion device (A) provided on both sides of the mounting portion (Q). (Not shown) operates to move the movable member (11) toward both side plates (c ₁ ) (c ₂ ) on the short side of the vertically dropped assembly tray (a) (Fig. 7). ).

Next, the cylinder (12
d) operates to slide the slide member (12) to hook the deployment hook (14) on the upper surfaces of the side plates (c ₁ ) (c ₂ ) (a and b in FIG. 8).

At this time, the insertion claws (13a) (13a) at the tip of the release piece (13) are
It is located at a position where it can be inserted into the insertion openings (d ₂ ) (d ₂ ) of both side plates (c ₁ ) (c ₂ ).

Then, by concatenated cylinder rotation axis (15) (15c) is activated, releasing pieces (13) rotates and the tip of the insertion nail (13a) (13a) are insertion opening (d ₂₎ (d ₂ ) Inserted from each side, press each flap (c ₃ ) inward, and hook (c ₄ )
(C ₄ ) is disengaged, and at the same time, the deployment hook (14) is rotated while being retained by the tips of both side plates (c ₁ ) (c ₂ ) to deploy each flap (c ₃ ) to the outside ( (C, d in Fig. 8).

Then, a cylinder (not shown) connected to the movable member (11) and a cylinder (15c) connected to the rotating shaft (15).
And a cylinder 12d connected to the slide member (12))
Respectively, the slide member (12) and the movable member (11) return to their original positions. (E in Fig. 8,
f).

When the assembling tray (a) is unfolded by the unfolding device (A), the supporting arm (19) rotates in the traveling direction to open the collapse space, and at the same time, the pressing plate (18) in the supporting member (18) is opened.
The cylinder (18b) connected to (a) operates to slide the pressing plate (18a) forward to press the inside of the back plate of the assembly tray (a) to transfer the tray (a) to the transfer device (D). Defeat it to the side.

Thus, the assembly tray (a) in which all the side plates have been developed and laid down on the transfer conveyor (21) of the transfer device (D) has the transfer pusher (21b) hooked at the rear end thereof, and the assembly tray (a) is laid down. It is transferred to the front side by traveling in (21).

During this transfer, a flap guide piece is inserted below the flap (c ₃ ) that is still folded inward to expand the flap (c ₃ ) to the outside, and at the same time, presser bar (22
By c), the flap (c ₃ ) is pressed so as not to return to its original state, disassembled into a single plate, and transferred to the discharge device side.

However, since the assembly tray (a) cannot be sent to just above the discharging device by the transfer conveyor (21), an auxiliary transfer mechanism is provided at the rear end of the assembly tray (a) transferred to the tip of the transfer conveyor (21). The locking plate (27) of the transfer plate (24) in (23) is locked, and the parallel movement of the transfer plate (24) by the operation of the cylinder (25) causes the assembly tray (a) to discharge the assembly tray (a). It is mounted on the movable mounting table (31) in E).

Thus, the cylinder (36) connected to the suction part (35) of the suction device (32) expands, and the vacuum cup (32b) of the suction part (35) descends onto the movable mounting table (31). Then, the plate-shaped assembly tray (a) on the movable mounting table (31)
When the movable chain (33) rotates, the pedestals (34) (34 ') move to both sides, and the push-down port (34a) through which the one-plate assembly tray (a) can pass. Is opened.

Next, the cylinder (36) is further extended, and the assembly tray sucked by the vacuum cup (32b) is lowered from the push-down opening (34a) to lower the mounting table (2) of the lifting mechanism (29).
9b). Then, the assembly trays (a) are placed on the placing table (29b) until a predetermined number of them are stacked.

After that, the assembly trays (a) stacked in a predetermined number

Claims (1)

[Claims] 1. A development of an assembly tray having an opening on the upper surface, which is formed by assembling the flaps of both side plates folded inward and the hooking pieces at the tips thereof hooked on the hooking openings of the back plate. The device is a movable member that is slidably provided on both sides of a machine frame so as to be slidable, a slide member that is slidably provided on the movable member in a direction orthogonal to the sliding direction, and the slide member is rotatable. A release piece that is provided at both upper and lower ends of a freely hung rotating shaft and is inserted into the insertion openings of the both side plates to release the engagement of the engagement piece, and the rotation axis has a substantially right-angled plane with the release piece. And a deployment hook for deploying the flap, which is unlocked by the release piece, to the outside.
