For this reason, the specified number of sachets counted by the count sensor are sequentially stacked on a tray arranged on the lower surface of the supply port by moving on the turntable, and when the number of sachets reaches the specified quantity, the shutter of the supply port is opened. Close.

The tray on which the specified number of pouches are stacked is transferred by the turntable in the direction of the transfer conveyor, and the next empty tray is transferred to the lower surface of the supply port by the turntable. When the shutter stops at the lower surface of the supply port and the shutter is opened, the small bags supplied from the supply conveyor are supplied into the empty tray. When a predetermined number of small bags are stacked on the tray, the shutter is closed, but the small bags are continuously supplied from the supply conveyor, so that the small bags are sequentially stacked on the shutter.

In the process of stacking pouches on the shutter, the trays that have been stacked are transferred in the direction of the transfer conveyor as described above, and the next empty tray is transferred.
The shutter is closed until the empty tray is transferred to the lower surface of the supply port, so that pouches continuously supplied from the supply conveyor are not dropped on the upper surface of the turntable. Then, when the tray is arranged on the lower surface of the supply port, the shutter of the supply port is opened, and the closed pouches are dropped on the tray by closing the shutter, and the pouches are dropped on the tray until the specified number is reached. It is a stack.

[0014] Further, the tray on which the pouches have been stacked and which has been moved to the position of the transfer conveyor by the turntable is moved to the position of the temporary storage section arranged above the transfer conveyor. Is pushed out, and a specified number of pouches stacked are pushed out and supplied to the temporary storage unit.

In the temporary storage section to which the small bags are extruded and supplied, the stacked small bags can be directly dropped and arranged on a transfer conveyor for transferring the lower surface. In this transfer conveyor, for example, a horizontal pillow packaging machine or the like for storing stacked small bags in a large bag is arranged in the direction of the transfer destination, and the stacked small bags are stored in a large bag. After the small bags stacked by the discharge cylinder are pushed out and stored in the temporary storage section, the tray is transferred toward the supply port according to the rotation of the turntable.

The stopper also operates when the tray is transferred to the temporary storage section on the turntable, and the movement of the tray is stopped while the small bag is being transferred to the temporary storage section by the discharge cylinder. Even when the tray is stopped, the turntable continues to rotate at all times, and only the turntable moves while sliding on the tray while the tray is stopped by the stopper.

As described above, the present invention enables continuous operation as a device for stacking and supplying a specified number of small bags, and enables accurate stacking of a specified number of small bags. This enables quick and accurate supply to the packaging machine.

Stop moving to face (16). The separate stopper (17) also protrudes from the fixing plate (15), and when the tray (11) on which the pouches (3) are stacked moves to a position corresponding to the temporary storage portion (16), the stacked pouches (3) are removed. A separate stopper (17) protrudes from the fixed plate (15) so that the tray (11) can be abutted and stopped until a discharge cylinder (18) described later discharges to the temporary storage portion (16). . The tray (11) stopped by the separate stopper (17) is detected by a tray sensor (9) arranged on the outer peripheral surface of the discharge cylinder (18).

The tray (11) is provided in a temporary storage (16).
The direction is opened to form an opening (20), and an insertion interval (21) is formed in the center direction of the turntable (12). The insertion interval (21) is formed by providing L-shaped side walls (22) on both sides of the tray (11).

On the upper surface of the turntable (12),
A discharge cylinder (18) supported by a support arm (24) raised from the floor (23) or the like is arranged.
The pressing arm (25) is fixed to (18), and the pressing arm (25) can be moved forward and backward. The pressing arm (25) is inserted into the tray (11) from the insertion interval (21) of the tray (11) to temporarily store a specified number of sachets (3) stacked on the tray (11). 16) Push out and store. This discharge cylinder
(18) shows that the tray (11) was stopped by the separate stopper (17) at the position facing the temporary storage portion (16),
The tray arm (9) senses and operates, and when the tray (11) is fixed at a position facing the temporary storage portion (16), the pressing arm (25) is moved to the tray ( 11) to discharge the stacked pouches (3).

Further, the tray (1) of the stacked pouches (3)
At the time of discharge from 1), an air outlet (26) for discharging pressurized air (27) upward is formed so as to be offset toward the turntable (12) side of the temporary storage section (16). The air outlet (26) is configured to blow out pressurized air (27) upward, and is pressed by the pressing arm (25) of the discharge cylinder (18) and sent out to the temporary storage part (16). As shown in FIG. 5, pressurized air (27) is blown to the stacked pouches (3), and the stacked pouches (3) in the process of dropping and transferring to the temporary storage portion (16) are placed on the lower surface. It is urged upward by pressurized air (27) from the direction.

As described above, the small bag is formed by the pressurized air (27).
By urging (3) upward, the stacked pouches (3) extruded from the tray (11) change their attitudes sharply downward at the end in the extruding direction, and temporarily change the posture to the temporary storage section (16). )
Prevents falling inside. As shown in FIG. 5, the stacked pouches (3) are discharged into the temporary storage section (16) while keeping the attitude close to the horizontal state arranged in the tray (11). Therefore, when the upward pressing by the pressurized air (27) is released, the stacked pouches (3) fall into the temporary storage section (16) in a state nearly horizontal.

By ejecting the pressurized air (27) in this manner, the stacked pouches (3) can be prevented from being shifted from the horizontal state in the tray (11) without being sharply inclined, and from being displaced in the stacked state. Therefore, when stored in the temporary storage section (16), the bag does not lose its posture and the specified number of stacked pouches (3) does not cause irregular displacement.

Then, the small bag (3) dropped and placed in the temporary storage section (16) is temporarily held by the transfer shutter (28). In addition, this temporary storage unit (1
A transfer conveyor (30) is disposed at the lower end of 6), and transfer projections (31) are projected from the transfer conveyor (30) at regular intervals, and are stacked at intervals of the transfer projections (31). The pouch (3) is stored, and is transported by being pressed by the transport projection (31). Therefore, the temporary storage unit (16)
When the transfer section (32) of the transfer conveyor (30) partitioned by the transfer protrusion (31) is exposed to the lower end of the transfer shutter (28), the transfer shutter (28) is opened and the stacked pouches (3) are transferred to the transfer conveyor (3). 30) is stored in the transfer section (32) and transferred.

This transfer conveyer (30) has a packing device such as a horizontal pillow packing machine (not shown) arranged in the direction of the transfer destination, and stores and packs the stacked small bags (3) in a large bag (33). It is. This large bag (33) stores only one set of stacked small bags (3) and does not store a large number of small bags (3). Big bag
(33) has a capacity enough to store the stacked pouches (3). Therefore, if the stacked pouches (3) are displaced or are messyly stacked, storage becomes impossible. Therefore, the pouches (3) must always be stacked in an aligned state. Therefore, the apparatus for stacking and supplying pouches (3) according to the method of the present invention is effective.

Since the present invention has the above-described structure, it is possible to efficiently stack a specified number of small bags, and to reliably transfer the stacked small bags to the packaging machine in an aligned state. This enables efficient and stable packaging of small bags.
