2. Description of the Related Art A conventional automatic packaging device is shown in FIGS. 8 and 9 (JP-A-4-327122). The conventional automatic packaging device shown in FIGS. 8 and 9 is for accommodating a certain amount of powder such as milk powder in a bag in a fixed amount, and a total of six chutes 11, 11, ... The bag 9 is attached to the chute 11 from the bag feeder 14 at the bag feeding position A at a bag feeding position A, and the raw material (powder) is roughly filled in the bag 9 at the first filling position B.
Similarly, at the filling position C, the bag 9 is filled with a medium amount of the raw material, and at the third filling position D, the bag 9 is filled with a small amount of the raw material so that the final and accurate weight is obtained. Next, after the air in the raw material in the bag 9 is removed at the vacuum degassing position E, the raw material-containing bag 90 is removed from the chute 11 at the detaching position F, and then the empty chute 11 reaches the bag feeding position A. Will be returned. The bag 90 containing the raw material removed from the chute 11 at the removal position F is the rotary lift table 1
7, the rotary lift table 17 is directed to the conveyor 19 side, and then the pusher device 18 sends the rotary lift table 17 onto the conveyor 19 and conveys it to the next process (for example, opening sealing process) side. The automatic packaging apparatus 1 is configured to perform such an operation in sequence and to successively store a fixed amount of raw material in a bag.

At the bag feeding position A, as shown in FIG. 9, a chute 11 from the bag bundle 9A placed on the bag placing table 7 in a stacked state by the bag feeder 14 sequentially one by one.
It is designed to be attached to. Then, when the bag 9 disappears (appears to disappear) on the bag placing table 7, a new bag bundle 9A (each bag is laminated with the opening portions in the same orientation) is manually placed on the bag placing table 7. Need to be replenished.

By the way, the bag 9 used in this type of automatic packaging apparatus is thicker at the closing side end (left side in FIG. 9) than at the opening side end (right side in FIG. 9). In the bag bundle 9A in which the bags are stacked in the same orientation,
As shown in FIG. 9, it is inclined downward from the closing side end toward the opening side. In addition, this type of bag is usually packed with 100 pieces as a unit, but a bag bundle of 25 pieces in the same direction is laminated in a state in which the posture is sequentially changed by an angle of 180 °, and the whole bag is stacked. The thickness is made uniform.

[0005]

However, in the conventional automatic packaging apparatus 1 shown in FIGS. 8 and 9, the supply of raw materials and the filling of raw materials into bags are automated and unmanned. , Only bag refilling work is done manually,
Every time the bag 9 is about to run out on the bag placing table 7 at the bag feeding position A, a new bag bundle 9A must be manually replenished on the bag placing table 7. Therefore, it takes manpower for the bag bundle refilling work, and it is necessary to keep an eye on the remaining amount of the bag, so that other work cannot be done (the worker is restrained to refill the bag). There was a problem. In addition, when refilling the bag on the bag placing table 7, if the bag is not placed properly, it may cause a bag feeding error to the bag feeder 14 or the chute 11.
Bag refilling work requires a great deal of caution. or,
Since it is necessary to stack the bags 9 on the bag placing table 7 in the same direction, all the bags 9 should be stacked on the bag placing table 7 at a time with a large number of sheets (for example, 100 sheets as one unit of packing). )
Cannot be loaded (if many bags are loaded at one time, the upper surface will be greatly inclined and become unstable as shown in FIG. 9 or the upper bag will slide forward and fall). The replenishment interval of the bundle 9A was shortened, and it was necessary to monitor the remaining amount of the bag frequently. In addition, a bag bundle of one unit (100 sheets) for packing is usually 180 in the state where 25 sheets are bundled together.
Although the bags are stacked by alternately changing their postures, in the conventional automatic packaging machine, the bags have to be stacked on the bag placing table 7 in the same direction. There was also a problem that the work of changing the posture of the laminated bags was troublesome.

In view of the above-mentioned problems of the conventional automatic packaging apparatus, the present invention enables the next bag bundle to be automatically replenished on the bag mounting table immediately when the bags on the bag mounting table run out. The first purpose is to further supply the unpacked 1 unit number (100 sheets) of bags to the bag placing table side as they are (25 sheets are stacked in alternating postures). The second purpose is to be able to use it without any trouble.

[0007]

In the automatic packaging apparatus with a three-dimensional warehouse according to the invention of claim 1, the chute for feeding the raw materials is sequentially moved between the bag feeding position, the raw material filling position, and the raw material containing bag removing position. At first, in the bag feeding position, the stacked bags on the bag placing table are sequentially loaded into the chute one by one, and then at the raw material filling position, a certain amount of the raw material is stored in the chute mounted bag. A three-dimensional warehouse is installed side by side in the vicinity of the device, and the three-dimensional warehouse has a real pallet in which a predetermined number of bags are stacked on the pallet.
Up to a plurality of upper and lower storage chambers that can be stored one by one, an elevating platform that can mount an actual pallet and can be vertically moved up and down along each storage chamber, and the elevating platform up to the height corresponding to each storage chamber A lift drive device that raises and lowers, a transfer device that transfers the actual pallet between the elevator and each storage chamber, and a transfer that transfers the actual pallet on the elevator to the bag mounting table on the bag supply position side And a device.

According to the second aspect of the present invention, in the automatic packaging apparatus with a three-dimensional warehouse according to the first aspect, the bag placing table and the table on which the actual pallet is placed are horizontally rotatably installed on the receiving table. The table was constructed by providing a rotary drive device for rotating the table by 180 ° in a horizontal plane per operation, and the bag drive machine took out a predetermined number of bags on the bag placing table. It is characterized in that it is made to operate one by one in sequence by a signal from a detecting means for detecting that.

[0009]

According to the first aspect of the present invention, the actual mounting pallets (those having a predetermined number of bags stacked on the pallets) are stored in advance in the respective storage chambers of the three-dimensional warehouses arranged in the vicinity of the automatic packaging device. However, at the time of storage, pressing the specified switch button, for example, with the actual pallet placed on the elevator will raise the elevator to the position corresponding to the storage room of the number of floors specified by the elevator drive device. Then, the transfer device stores the actual pallet on the lift table in the designated storage chamber. After that, the elevating table is lowered to the original position, and the actual mounting pallets can be stored (stock) in the respective storage chambers in the same manner in sequence.
In addition, the actual pallet storage work in such a storage room,
It is carried out using the free time during the bag feeding work by the bag feeding machine,
We are trying to prevent the loss of time (interruption of bag supply work) due to storage work.

On the other hand, at the bag feeding position, the actual loading pallet is placed on the bag loading table, and the bags of the actual loading pallet are sequentially fed to the chute side one by one from the upper side by the bag feeding machine. Has become. Then, when the number of remaining bags on the bag placing table reaches a predetermined small number, for example, an appropriate signal such as a bag consumption number detection signal from the bag feeder side activates the lifting drive device to specify the lifting table. Then, the actual loading pallet in the storage chamber is received on the lift table by the transfer device, and then the lift table is moved to a position in the vicinity of the bag loading table and kept waiting there. Then, when the bags on the bag placing table are exhausted, the actual loading pallet on the elevating table, which was standing by in the vicinity of the bag placing table, is transferred onto the bag placing table by the transfer device. In that case, the actual pallet on the lifting table side may be directly transferred to the bag loading table side, or the actual loading pallet may be interposed between the lifting table and the bag loading table in advance (one delay). Also, the actual pallet may be transferred. When transferring the actual pallet, it is necessary to remove the empty pallet that was on the bag placing table, but this empty pallet removal work may be done manually, or it can be automatically pushed by pressing the subsequent actual pallet. May be excluded from the bag mounting table. In addition, when the actual pallet is automatically removed from the bag mounting table, the removed actual pallet can be automatically transferred to the entrance side of the three-dimensional warehouse.

As described above, in the automatic packaging apparatus with a three-dimensional warehouse according to the first aspect of the present invention, when no bags are left on the bag placing table at the bag feeding position, the actual pallet stocked in the storage room of the three-dimensional warehouse is emptied. It can be automatically replenished on the empty bag holder.

Further, in the automatic packaging apparatus with a three-dimensional warehouse according to claim 2 of the present application, the bag placing table is configured such that the table on which the actual pallet is placed can be rotated by 180 ° in the horizontal plane by the rotation driving device. There is. Further, the rotation drive device is operated one by one in sequence by a signal from the detection means that is issued each time the bag feeder is operated a predetermined number of times (supplying a predetermined number of bags to the chute side). Then, as the actual pallet, a bunch of unpacked bags (for example, 100 bags in total, 25 are stacked in a state where the postures are alternately changed by 180 ° at an angle) are directly placed on the pallet. Even in this case, the posture of each bag (the direction of the opening) can be automatically corrected to the proper direction at the bag feeding position. Therefore, it is not necessary to correct the direction of each bag of the unpacked bag bundle, and even if a large number of bags (for example, 100 bags) are stacked, the directions can be alternately changed by 180 ° and used. Therefore, the stacking posture is stable (the upper surface side is not largely inclined). When using a stack of all bag bundles in the same direction, the detection means for detecting the number of times of operation of the bag feeder is turned off so that the rotary drive device is not operated (the table is not rotated). You can also

[0013]

According to the automatic packaging apparatus with the three-dimensional warehouse of the first aspect of the present invention, the actual loading pallet (a predetermined number of bags are stacked on the pallet) is stocked in each storage chamber of the three-dimensional warehouse, and the bag is supplied. When there are no more bags on the bag placing table at the position, the loading pallets stocked in the storage chamber can be automatically supplied to the bag placing table by the lifting table, the lifting drive device, the transfer device, and the transfer device. . Therefore, in the automatic packaging apparatus with the three-dimensional warehouse according to claim 1 of the present invention, the bag replenishing work on the bag placing table can be automatically performed without manual labor, which simplifies the bag replenishing operation and leaves the remaining bag on the bag placing table. This has the effect of eliminating the need for a worker to monitor the bag.

Further, in the automatic packaging apparatus with a three-dimensional warehouse according to claim 2 of the present application, the table on which the actual pallet is placed can be horizontally rotated by an angle of 180 ° by a rotary drive unit, and the rotary drive unit is further provided. Is designed so that it can be operated once each time a specified number (for example, 25) of bags on the bag mounting table have been taken out, so one unit of unpacked bag bundle (for example, a total of 100 bags The posture of each bag (the orientation of the opening), even when an actual pallet is placed on the pallet as it is, with 25 sheets alternately stacked with the posture changed by 180 ° ), The posture of the bag can be automatically corrected in the proper direction. Therefore, it is possible to use the bag bundle as it is unpacked (the orientation of the openings is displaced by 180 ° for every 25 sheets) on the pallet as it is. Even when a large number of bags are stacked on the pallet at one time, the stacking posture can be stabilized by changing the direction of the bags.

The transfer device 6 transfers the actual pallet 10 on the lift table 3 to the bag mounting table 7 side. In this embodiment, the transfer device 6 is also used as the transfer device 5. is doing.

Next, the transfer device 5 and the transfer device 6
The operation of will be described together with the method of using the three-dimensional warehouse 2.

First, the actual pallet 10 is stored in the storage chambers (L ₁ ~
To housed in L _4, R ₁ ~R ₄₎ inside, as shown in FIG. 3, keep the actual mounting pallet 10 is supplied to where waiting the inlet side standby chamber 24. At this time, the actual pallet 10
Is locked by an entrance-side stopper 61 and a retractable stopper 64 at a predetermined standby position in the entrance-side standby chamber 24. Then, when the storage switch button for instructing a predetermined storage chamber is pressed, the carriage 3 of the lift 3 is driven by the forward / backward drive device 34.
2 has moved to the right side position indicated by the reference numeral 32 'in FIG. 4 (at this time, the stoppers 61, 64 of the entrance side standby chamber 24).
Are unlocked), and the motor 53 of the transfer device 5 is operated to drive the upper surfaces of the travel zones 50, 50 to the left. Then, the engagement pins 52, 52 on the front and rear sides of the traveling belts 50, 50 engage with the left side locking pieces 82, 82 of the actual pallet 10 waiting in the inlet side standby chamber 24 from below ( (State of reference numeral 52 'in FIG. 4), traveling zone 50,
As the vehicle 50 further moves to the left, the actual pallet 10 that was on the inlet side standby chamber 24 side is transferred to the lift table 3 side. At this time, the actual pallet 10 is softly locked by the automatic lock device 37 (FIG. 4) on the lift table 3. Next, the motor 44 of the lifting drive device 4 is rotated a number of times corresponding to the number of floors of the designated storage room,
The elevating table 3 on which the actual pallet 10 is placed is raised to a predetermined height and stopped there. After that, when the designated empty storage chamber is on the right side (R _{1 to} R ₄ ), the carriage 32 remains as it is (right side position indicated by reference numeral 32 ′), but the storage chamber is on the left side (L _{1 to} L ₄ ). In this case, the dolly 32 is moved to the left side position as indicated by reference numeral 32 ″. Next, when the traveling belts 50, 50 of the delivery device 5 are caused to travel to the storage chamber side designated by the motor 53, the lift table 3 is lifted. The upper loading pallet 10 is sent into the storage chamber, and the loading operation of the loading pallet is completed. When performing the loading operation continuously, the empty lifting platform 3 is returned to its original position. When the storage pallet 10 is lowered, the next pallet 10 is similarly operated to be stored in another storage chamber, and the pallet 10 is sequentially stored in each storage chamber. Three
It suffices to wait for a position corresponding to a predetermined storage chamber. It should be noted that the storage operation of the actual pallet may be programmed in the controller so that a predetermined empty storage chamber is automatically selected by simply operating the storage button.

When the actual pallet 10 in the storage chamber is taken out to the exit side standby chamber 25, the take-out switch button for designating a predetermined storage chamber in which the actual pallet is stored is pushed (or simply A predetermined actual storage room may be automatically selected only by operating the take-out button), and the empty lifting platform 3 moves up to the designated number of floors, and then the trolley 32 stores the designated storage space. After being moved to the chamber side (reference numeral 32 'or 32 "in FIG. 4), the delivery device 5
The actual pallet 10 in the storage chamber is lifted by the elevator 3
To the side (running belts 50, 50 run to engage pin 5
2 is engaged with the locking piece 82 of the actual pallet 10 and the actual pallet 10 is further moved to the lift table 3 side),
Next, the elevating table 3 is moved down to the lowest stage, and then the transfer device 5 sends the actual pallet 10 on the elevating table 3 into the exit side standby chamber 25. In this embodiment, when the actual pallet 10 is supplied from the lifting table 3 side to the bag loading table 7 side, it is carried out via the exit side standby chamber 25, so that inside the exit side standby chamber 25 The on-board pallet 10 is always stored and kept on standby.

Actual pallet 1 in the exit side standby chamber 25
In order to transfer 0 to the bag placing table 7 side, the receiving table 7 of the bag placing table 7
2 is moved by the advancing / retreating drive device 74 to the right side position (indicated by the solid line in FIG. 6) 72 'in FIG. By sending out the loading pallet 10, another loading pallet 10 that has been waiting in the exit side waiting chamber 25 can be pushed out onto the table 73 of the bag loading table 7.

Then, the actual pallet 10 is placed on the table 73.
After being transferred onto the table 73, the table 73 is moved back and forth to drive the table 74.
Is moved to the left side to position the actual pallet 10 on the table 73 directly below the bag feeder 14.

Further, the bag feeder 14 has a bag bundle 9 on the bag placing table 7.
Bags 9 in sequence from the top side of A (on the actual pallet 10)
One by one is attached to the chute 11, the bag feeder 14
A detection means (for example, a counter) 20 is provided to detect the bag 9 each time a predetermined number (25) of bags 9 is supplied to the chute 11. On the other hand, the bag bundle 9A on the actual pallet 10 is stacked in a state where the bag opening portions are alternately displaced by a predetermined number (25 sheets) by an angle of 180 °, and the bag feeding machine 14 is a predetermined number (25 sheets). Each time the bag 9 is supplied to the chute 11, the rotation driving device 77 is operated once by the signal from the detecting means 20 to move the table 73 at the angle 180.
It is designed to rotate horizontally by °. By doing so, even with the bag bundle 9A stacked in a state in which the directions of the bag openings are alternately displaced by a predetermined number, the bag openings can be sequentially and automatically corrected in the proper direction and unpacked. Raw material filling work can be performed without any problem even if the bag bundle is used as it is. Further, the table 73 is adapted to be rotated at a position leftwardly separated from the actual pallet 10 waiting in the exit side standby chamber 25 by an appropriate distance. Therefore, the table 73 and the upper portion thereof are rotated at the time of rotation. The mounted pallet 10 that has been mounted does not collide with the mounted pallet 10 on the exit side standby chamber 25 side.

For storing the actual pallets 10 in the respective storage chambers, the bag feeder 14 shoots the bags on the bag placing table 7 into the chute 1.
It is performed during the surplus time being supplied to the 1 side, and the bag placing table 7
When the remaining number of upper bags is reduced to a predetermined number, the operation of storing the actual pallets is interrupted and the preparation operation for transferring the actual pallets to the bag placing table 7 side is performed. That is, the elevating table 3 on which the actual pallet 10 is placed is made to stand by at the lowest position so that the actual pallet transfer operation can be performed immediately when the bags on the bag placing table 7 are exhausted. When the actual pallet 10 is transferred from the outlet side standby chamber 25 side to the bag placing table 7 side, it is necessary to remove the empty pallet 8 on the bag placing table 7. Is the removal operation manually performed? Alternatively, an appropriate automatic discharging mechanism may be provided.

As can be seen from the above description, when the three-dimensional warehouses 2 having the above-mentioned configuration are installed in parallel in the vicinity of the automatic packaging device 1, the actual pallets 10 are automatically and sequentially supplied onto the bag placing table 7 at the bag feeding position A. Therefore, manual operation is not required for the bag refilling operation on the bag placing table 7.

In this embodiment, when the actual pallet 10 is transferred from the lifting table 3 side to the bag loading table 7 side, the transfer device 6 provided on the lifting table 3 (also serves as the transfer device 5). By pushing out the actual pallet 10 on the lift table 3 into the exit side standby chamber 25, the actual pallet 10 in the exit side standby chamber 25 is transferred to the bag placing table 7 side (indirectly in a so-called bead shape). However, depending on the structure of the three-dimensional warehouse 2, the actual pallet 10 can be directly transferred from the lifting table 3 side to the bag mounting table 7 side. Further, in this embodiment, the transfer device 6 and the delivery device 5 are also used, but these devices may be provided separately.

Further, in this embodiment, for example, a stack of 25 bags whose openings are oriented in the same direction is sequentially displaced by an angle of 180 ° and stacked, but the entire stack of bags is stacked in the same direction. When using the above, the detecting means 20 for detecting the number of times the bag is taken out of the bag feeder 14 can be turned off so that the rotation drive device 77 is not operated (the table 73 is not rotated).
