Next, the operation of the present embodiment will be described.

In the bag unpacking apparatus 10 having the above-described structure, the bags H accommodating the grains are stacked in advance on the pallet P, and the pallet P on which the plurality of bags H are stacked is placed on the pallet by a forklift or the like. It is placed on the unit 12.

Here, the bags H stacked on the pallet P are, for example, as shown in FIG.
As shown in FIG. 10A, they are arranged in an "A arrangement pattern", and further arranged thereon and arranged in a "B arrangement pattern" as shown in FIG. 10B. ) Are alternately repeated, and are usually stacked in seven to eight stages. For example, in the case of “5 bags”, they are arranged in a “C arrangement pattern” as shown in FIG. 10C, and further arranged in a “D arrangement pattern” as shown in FIG. , And after that, "C
The “array pattern” and the “D array pattern” are alternately and repeatedly repeated in order, so that a total of seven to eight stages are stacked.

A plurality of bags H stacked as described above
Is the table plate 1 of the pallet mounting portion 12 with the pallet P being stacked on the pallet P.
4.

Next, the bag opening device 10 is started. At this time, when the bag opening apparatus 10 is started, it is determined whether the bags H stacked on the pallet P are "7 bags" or "5 bags" as described above, and buttons are set. A button is set by selecting whether the arrangement pattern of the uppermost bag H is “A arrangement pattern” or “B arrangement pattern”, or “C arrangement pattern” or “D arrangement pattern”. Based on this setting operation, the order in which the bags are grabbed (in other words,
The gripping position is determined, and the subsequent operation is controlled.

When the apparatus is started by performing various setting operations as described above, the table plate 14 of the pallet placing section 12 is activated.
Rises, and when the topmost bag H reaches a predetermined position, the topmost bag H is detected by the bag detection sensor 16. Thereby, the table plate 14 is stopped, and the uppermost bag H on the pallet P is held at the predetermined gripping position. That is,
At this point, the three-dimensional (X-axis, Y-axis,
Of the gripping positions (in the Z-axis direction), the vertical gripping position (position in the Z-axis direction) is set.

Next, the gripper 18 is operated, and the bags H on the pallet P are sequentially gripped.

That is, the gripping claw 24 and the driving pin 26 move forward along the front-rear drive guide 22 toward one of the uppermost bags H on the pallet P, which is a bag to be grasped. Then, as shown in detail in FIGS. 6 and 7, the movement position detection sensor 32 further includes the bag H
Is detected, the grasping claw 24 and the driving pin 2
The forward movement of No. 6 is rapidly decelerated, and stopped immediately before the bag H by a predetermined distance (for example, 150 mm). Further, when the gripping claw 24 and the driving pin 26 stop, the air cylinder 28 is simultaneously operated to rotate the gripping claw 24,
The gripper 24 is driven into the bag H from above (the driving depth of the gripper 24 is, for example, 80% of the thickness of the bag H). At about the same time, the driving pin 26 is driven forward by the operation of the air cylinder 30, and the driving pin 26 is driven into the bag H from the rear side. As a result, the bag H is reliably held by the holding claws 24 and the driving pins 26.

Thereafter, the gripping portion 18 (grip claw 24 and driving pin 26) moves backward along the front and rear drive guide 22, and the bag H is gripped by the gripping claw 24 and driving pin 26. Delivery guide 3 as it is
It is carried to four. As shown in detail in FIGS. 8 and 9,
When the bag H reaches the rotating plate 38 of the delivery guide unit 34, the release position detection sensor 42 detects this,
The air cylinder 28 and the air cylinder 30 are operated, and the bag H by the gripper 24 and the driving pin 26 is moved.
Is released. Further, after a predetermined timing, the air cylinder 40 is operated, and the rotating plate 3
8 is rotated from the horizontal state to the inclined state. As a result, the bag H is dropped and fed downward while being guided by the rotating plate 38.

After the gripping of the bag H is released, the gripping claws 24 and the driving pins 26 further move back along the front and rear drive guides 22 to return to the initial position. After the bag H is dropped and fed, the rotating plate 38 rotates again from the inclined state to the horizontal state and returns to the initial position.

The bag H guided by the rotating plate 38 and fed downward reaches the cutter unit 44 which is already rotationally driven. In the cutter unit 44, the fed bag body H is cut by the plurality of disk blades while the grains are stored. In this case, the cutter unit 44
Number of rotary shafts (disc blades) located at the center
Since (for example, two) rotating shafts are mounted higher (at a higher position) than the other rotating shafts, the impact upon receiving the bag H dropped and fed from the rotating plate 38 is dispersed. Then, the cutting operation of the bag body H is performed smoothly.

Further, the cut bag H (bag piece)
And the grain inside falls into the sorting part 46 provided immediately below the cutter part 44. In the sorting unit 46, the cut bag pieces and the grains inside are separated and sorted by the sorting net 48, and the cut grains in the bag body H pass through the mesh of the sorting net 48. The bag pieces that have been cut are temporarily accumulated on the sorting net 48.

Further, in the sorting section 46, the chain conveyor 52 has already been operated, and the cut bag pieces temporarily stored on the sorting net 48 are scraped out by the scraping bar 50 in the machine width direction. Is discharged to the outside through the discharge port 54.

With the above, the unpacking process of the first bag H is completed, and thereafter the same process as described above is performed for the bags H,.
It is sequentially repeated in the order of.

When the second and subsequent bags H are to be gripped, the arrangement pattern of the uppermost bag H among the bags H stacked on the pallet P is "A arrangement". The operation of the gripping unit 18 is performed in accordance with a “bag gripping sequence (grip position)” which is set in advance based on whether the “pattern”, “B array pattern”, “C array pattern” or “D array pattern”. When the gripper 24 and the driving pin 26 move along the front and rear drive guides 22 and the front and rear drive guides 22 themselves move along the left and right drive guides 20, the gripper 24 and the driving pin 26 move on the pallet P. Is moved to the gripping position corresponding to the bag H of the second bag and thereafter. That is, grasping claw 2
4 and the driving pin 26 move in the horizontal direction, so that the three-dimensional (X-axis, Y-axis, and Z-axis) gripping positions of the bag body H (X-axis) , And the position in the Y-axis direction) are set, and the same steps as described above are sequentially repeated.

After all the uppermost bags H described above have been processed, the table plate 14 of the pallet placing portion 12 is raised again. When the next uppermost bag H reaches a predetermined position, the bag detection sensor 1
6, the table plate 14 is stopped. Thereafter, the same steps as described above are sequentially repeated.

When all the bags up to the lowermost stage H have been processed in this way, the table plate 14 of the pallet placing portion 12 descends and stops at the lowest position. The empty pallet P is removed from the table plate 14 by a forklift or the like, and a new pallet P on which bags H containing grains are stacked is placed instead.

As described above, in the bag opening apparatus 10 according to the present embodiment, the bags H containing the grains and stacked on the pallet P are grasped by the grasping section 18 and the bags H are directly used as the cutter section. In order to separate and accumulate the cut pieces of the bag body and the grains inside after cutting into a state in which the grains are stored while being fed to the bag 44 and take out the grains from the bag body H, A series of operations of accumulating at a location can be performed sequentially and automatically and extremely efficiently, greatly improving the operation efficiency.

Here, the gripping claws 24 are stabbed into the bag body H by being displaced substantially downward (turned downward) from the state of being disposed above the bag body H. Thereby, the movement of the bag H in the horizontal direction is prevented. Further, the driving pin 26 is stabbed into the bag H by being displaced in a substantially horizontal direction from a state of being arranged on the side of the bag H.
Thereby, the vertical movement of the bag body H is prevented. In this manner, the gripper 2 is prevented from moving in the horizontal direction by the gripper 24 while the vertical movement of the bag H is prevented by the driving pin 26.
4 and the driving pin 26 to grip the bag H
The bag H can be firmly grasped.

Further, when the gripper 24 is pierced into the bag H, the movement of the bag H in the horizontal direction is hindered. Immediately thereafter, the driving pin 26 is pierced into the bag H, so that the driving pin 26 is securely inserted. It can pierce the bag H. Therefore, the bag H can be reliably grasped.

Also, since the gripping claws 24 (the plurality of claws 24A) are curved along the direction of rotation of the gripping claws 24, when the gripping claws 24 are rotated, the ends of the gripping claws 24 are moved from the distal ends thereof. All parts extending to the end rotate on the same orbit (on the same arc). Thereby, the resistance at the time of piercing the grasping claw 24 into the bag H can be reduced, and the grasping claw 24 can be easily and surely moved to the bag H.
Can be pierced. Therefore, the bag H can be grasped more reliably.

Further, the thin pins 26 of the driving pins 26
Since A protrudes slightly obliquely upward, when the gripping claws 24 and the driving pins 26 grip the bag H, the front end of the bag H in the transport direction is, for example, approximately 25% of the thickness of the bag H.
It will be in a raised state. Therefore, even if there is an obstacle (another bag H or the like) below the bag H in the transport path of the bag H to the delivery guide section 34, the bag H can easily get over the obstacle, Thereby, it is possible to prevent the bag H from falling off from the gripping claws 24 and the driving pins 26 during the conveyance of the bag H.

Further, a plurality of fine pins 26A of the driving pins 26 are provided vertically and a plurality of rows are provided horizontally. For this reason, even if the advance movement position of the driving pin 26 in the direction of the bag body H is shifted or the thickness or width of the bag body H is different from the normal one, at least a part of the thin pin 26A is pierced into the bag body H. Can be. Here, while some thin pins 26A of the plurality of thin pins 26A are pierced into the bag body H to be grasped, the other thin pins 26A are temporarily set to an object other than the bag body H to be grasped (another bag). Even when the gripping claw 24 and the driving pin 26 move backward to the delivery guide portion 34 side even when pierced into the body H, the delivery guide portion 34 by the gripping claw 24 is held only in the bag body H to be gripped. The thin pin 26A pierced into the bag H is not disengaged due to the force of the transfer to the bag H, and the object other than the bag H to be grasped is conveyed by the grasping claw 24 to the delivery guide portion 34 side. The thin pin 26A pierced by this object comes off without any force. Accordingly, it is possible to prevent the object other than the object to be grasped from being grasped by the grasping claw 24 and the driving pin 26 and conveyed to the delivery guide unit 34 side.

In the present embodiment, the driving pin 26
Although the thin pins 26A are provided in a plurality of rows vertically and in a plurality of rows horizontally, a plurality of thin pins of the driving pins may be provided in a random arrangement.
