Many cereal bags are sequentially stacked on a predetermined pallet, and in this state, each pallet is stored in a storage or transported between processing facilities. Furthermore, when performing subsequent processing, for example, when collectively storing in a storage tank or when processing rice milling or the like with a processing device, the grains contained in such a grain bag are taken out of the grain bag again, It is embedded in storage tanks and individual processing equipment.

Heretofore, conventionally, when the grain is taken out again from the grain bag transported to the storage tank or the processing apparatus as described above, the grain bags stacked on the pallet are further removed one by one by a worker. In addition, these cereal bags were manually opened, and the cereal inside was taken out for each bag. That is, even if a large number of grain bags are transported to a storage tank or a processing device at a time by mechanical force (e.g., a hawklift), the subsequent work of taking out grains has to be performed manually for each bag.
A great deal of labor is required, the workability is extremely poor, and measures for this have been eagerly desired.

The present invention has been made in order to solve the above-mentioned problems, and automatically and automatically collects cereals from a bag containing grains such as rice grains at a predetermined location. It is an object of the present invention to provide a bag opening apparatus that can be implemented extremely efficiently and greatly improves workability.

Therefore, the grains in the bag body H after being cut by the cutter unit 44 pass through the mesh of the sorting net 48, fall down as they are, are accumulated, and the bag pieces cut by the cutter unit 44 are This is a configuration that temporarily accumulates on the sorting net 48.

On the sorting net 48, a scraping bar 50 is provided. The scraping bar 50 is attached to a chain conveyor 52 arranged along the width direction of the apparatus. When the chain conveyor 52 is operated by a motor 56 connected to the chain conveyor 52, the scraping bar 50 is separated from the sorting net 48. It is configured to move on. Thereby, the bag pieces cut by the cutter unit 44 and collected on the sorting net 48 can be scraped out in the width direction of the apparatus and discharged to the outside through the discharge port 54.

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

In the unpacking apparatus 10 having the above-described structure, the bags H containing 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, in the case of "7 bags", as shown in FIG.
As shown in FIG. 8A, the array is arranged in the “A array pattern”, and further, as shown in FIG. 8B, the array is arranged in the “B array pattern” and stacked. They are sequentially and 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. 8C, and further arranged in a "D arrangement pattern" as shown in FIG. 8D. Stacking, and then "C array pattern"
And the “D array pattern” are alternately and sequentially repeated, and are stacked up to a maximum of seven to eight stages as a whole.

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 unpacking apparatus 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. Further, when the movement position detecting sensor 32 detects the bag H, the forward movement of the grasping claw 24 and the driving pin 26 is rapidly decelerated, and the time before the bag H is moved by a predetermined distance (for example, 150 mm). Stopped at 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, and the gripping claw 24 is driven into the bag body H from above. 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 gripped by the claws 2
4 and the driving pin 26 are surely grasped.

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. The bag body H is the delivery guide section 34
When the release position detection sensor 42 detects this, the air cylinder 28 and the air cylinder 30 are operated, and the gripping claw 24 and the driving pin 2 are moved.
The gripping of the bag H by 6 is released. Further, after a predetermined timing, the air cylinder 40 is operated, and the rotating plate 38 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 has been driven to rotate. In the cutter unit 44, the fed bag body H is cut by the plurality of disc blade shafts 60 while the grains are stored.

Further, the cut bag H (bag piece) and the grain inside fall into the sorting unit 46 provided immediately below the cutter unit 44. In the sorting unit 46, the cut pieces of the bag body and the grains therein are separated and sorted by the sorting net 48, and the grains in the bag body H after the cutting pass through the mesh of the sorting net 48. The bag pieces that have fallen down and are collected as they are, while being
8 temporarily accumulates.

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. Are discharged from the discharge port 54 to the outside.

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 grasped, the arrangement pattern of the topmost bag H among the bags H stacked on the pallet P is the "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.

In this way, when all the bags up to the lowermost stage H are processed, 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 the state in which the grains are accommodated by feeding to the bag 44, the grains are taken out of the bag body H to a predetermined location. Can be automatically and extremely efficiently performed sequentially and continuously, and the work efficiency is greatly improved.

Here, as shown in detail in FIGS. 6 and 7, the cutter section 44 has a disk blade 64 having a substantially disk shape and having a blade formed on the outer periphery on a rotating shaft 62 (on the same axis). Since a plurality of disk blade shafts 60 fixed and provided in a predetermined number are arranged substantially in parallel, the bag body H can be efficiently and finely cut by rotating the disk blade shafts 60.
Therefore, the grain is less likely to be caught by the cut bag piece, and the bag piece and the grain can be reliably separated and sorted.

Further, since the adjacent disk blade shafts 60 are rotated in opposite directions, the bag body H is easily caught between the disk blade shafts 60 by the rotational force of the adjacent disk blade shafts 60. Thereby, the bag body H can be reliably cut.

Further, since a predetermined number of disk blade shafts 60 arranged at the center of the cutter portion 44 are provided above the other disk blade shafts 60, the disk blade shaft 60 is supplied by the bag body H supplied to the cutter portion 44. The impact acting on the bag body H can be dispersed and relieved, the cutting operation of the bag body H can be performed smoothly, and the cutter portion 44 can be protected.

Further, since the intervals between the disk blades 64 fixed to the same disk blade shaft 60 (on the same axis) are separated by a predetermined distance (the interval A in FIG. 6 is widened to some extent), it is cut. The piece of the bag body after the cutting is
4 is prevented from being caught in the gap (between the gaps 4) and easily falls downward (on the sorting net 48). As a result, all of the cut pieces of the bag are cut off by the scraping bar 50 and the outlet 54
And the bag pieces can be easily and reliably accumulated.

Further, since the disk blades 64 of the adjacent disk blade shafts 60 overlap each other and are close to each other (the interval B in FIG. 6 is narrowed), the bag body H is made thinner. In addition to being able to be cut, it is possible to prevent the bag pieces after cutting from being connected in a strip shape. As a result, the bag pieces and the grains can be more reliably separated and sorted.

Here, the rotating shaft 62 of the disk blade shaft 60
The winding prevention rods 68 and 72 provided in the vicinity and near the disk blade 64 prevent the bag piece from being wound around the rotating shaft 62. As a result, the bag pieces gradually wrap around the rotating shaft 62 in multiple layers, so that the disc blade shaft 60
Can no longer be cut.

In this embodiment, the winding prevention rod 68
Although the (winding prevention member) is configured to be laterally provided on the side wall 66B of the support cylinder 66, the winding prevention bar 68 is configured to be erected on the beam member 70 below the support cylinder 66 similarly to the winding prevention bar 72. Is also good.

[0051]

As described above, the bag-opening apparatus according to the present invention performs the operation of taking out grains from the bags stacked on a pallet in which grains such as rice grains are stored, and accumulating the grains at a predetermined location. It can be performed automatically and extremely efficiently, and has an excellent effect that workability is greatly improved. Furthermore, since the bag member is prevented from being wound around the rotating shaft of the disk blade shaft by the winding prevention member, it is possible to prevent the disk blade shaft from being unable to cut the bag body.
