It is composed of a plurality of lower locking plates 21.

The fork bodies 17 on both sides are respectively attached at a predetermined interval to a pair of shafts 24 that are suspended horizontally at the lower portions of both sides of the support frame 16. The article B is supported on the support portion 26 which is opened and closed and is horizontal in the closed state.

The support portion 26 of the fork body 17 is provided with joint portions 29 at two locations, and each joint portion 29 is provided at two locations.
The tip end side of 9 is formed so that it can be bent only upwardly.

The alignment plates 18 on both sides are supported by the support frame 16 via a plurality of arms 32 so as to be movable in horizontal directions on both sides, and are moved in opposite directions by air cylinders 33 to open and close. It's getting old.

The stopper plate 19 is vertically moved up and down by an air cylinder 36 provided on the front surface of the support frame 16.

The locking plate 20 is rotatably supported on the rear surface of the support frame 16 via an arm 39, and by rotating the arm 39 with an air cylinder 40,
It is designed to rotate between a vertically lowered state and a horizontally retracted state.

The lower locking plate 21 is connected to the alignment plates 18 on both sides.
The air cylinder 43 rotates between a state in which it is vertically lowered and a state in which it is retracted horizontally outward.

The position where the lower locking plate 21 is provided is the position where the fork body 17 should be provided, as shown in FIG.
By this, fork body 1
7 and lower locking plates 20 are provided at equal intervals.

Furthermore, a roller conveyor 46 is located at the alignment position 1.
is provided. This roller conveyor 46 is
A plurality of rollers 48 are arranged in parallel on a shaft between the side frames 47 on both sides, and a motor 49 is installed at the lower center of each roller 48.
An endless V-belt 50 driven and rotated by a push-up pulley 51 is pressed into contact with the belt 50, and the goods B are conveyed in two directions to the loading position.

Cutouts 54 are provided in the side frames 47 on both sides of the roller conveyor 46, corresponding to the gaps between the rollers 48, and the cross-sections of the cutouts 54 extend from the outside to the inside. A groove-shaped insertion guide 55 is provided in a downwardly inclined manner.

The insertion guide 55 is provided corresponding to each fork body 17 of the transferred cargo holding device 15.

Further, a pallet conveyor 58 consisting of a driven chain conveyor is disposed at the loading position 2, and a storage and supply device 59 for pallets P is provided at the base end of the pallet conveyor 58. A stopper 60 for positioning the pallet P at the loading position 2 is located in the center between the pair of endless conveyance chains 61 of the pallet conveyor 58, and is provided so as to be retractable from the conveyance surface thereof.
A non-driven roller conveyor 62 is connected to the distal end thereof, and a stopper 63 is provided at the distal end of the roller conveyor 62.

Next, the operation will be explained.

In addition, in the explanation, the fork bodies 17 and the alignment plate 18 on both sides of the transfer cargo holding device 15 are in an open state,
The stopper plate 19 is in the lowered state, the locking plate 20 and the lower locking plate 21 are in the raised and retracted state, the horizontal movement frame 12 is located in the aligned position, and the pair of elevating bodies 7 are in the lowered position, As a result, the tips of the supporting parts 26 of the fork bodies 17 on both sides of the transfer cargo holding device 15 are connected to the insertion guides 55 on both sides of the roller conveyor 46, as shown on the right side of FIG.
It is assumed that the support part 26 is on standby in a bent state by the joint part 29 thereof.

In this state, one pallet P is supplied from the storage/supply device 59 onto the base end of the pallet conveyor 58, and this pallet P is conveyed to the loading position 2 by the pallet conveyor 58 to be placed in the ascending state. The articles B are positioned by a stopper 60 and sequentially fed onto the roller conveyor 46.

It is assumed that the articles B are supplied on the roller conveyor 46 so that a predetermined number of articles B form a predetermined loading pattern.

Then, the supplied items B come into contact with the front stopper plate 19 and are aligned on the front side. After that, when the items B for one stage are aligned, the fork bodies 17 and the alignment plate 18 on both sides close, The locking plate 20 is lowered, and thereby one stage of items B
Both sides and the rear part of the fork bodies 1 are aligned by the alignment plates 18 and the locking plates 20 on both sides, and the fork bodies 1 on both sides are aligned.
The support portion 26 of No. 7 is attached to the roller conveyor 46 along the insertion guide 55 as shown on the right side of FIG.
One stage of items B is inserted through the notch 54 of the side frame 47 of
It is inserted between the rollers 48 below.

Note that, when the fork body 17 is completely closed, the support portion 26 of the fork body 17 separates from the insertion guide 55, and each joint portion 29 becomes straight and horizontal due to its own weight.

Next, the pair of elevating bodies 7 rise and scoop up one stage worth of items B from the roller conveyor 46 using the supporting parts 26 of each fork body 17, and the supporting parts 26 are placed at a position slightly higher than the pallet P (this is one stage). When loading the second item B, when the second and subsequent tiers have risen to a position slightly higher than the lower item B, stop raising 7 and move the horizontal movement frame 12 to loading position 2. , move item B directly above pallet P (directly above item B in the lower tier from the second stage onwards).

Note that when the horizontal movement frame 12 starts moving,
Item B tends to shift backward due to inertia, but this shift is prevented by the locking plate 20, and when the horizontal movement frame 12 moves and stops, item B will shift forward due to inertia. It's easy, but the stopper board 1
9 prevents this shift.

Then, the lower locking plates 21 on both sides are lowered to come into contact with both sides of the pallet P (both sides of the lower item B in the second and subsequent stages).

Note that, as in this example, when the dimensions of the pallet P and the external dimensions of the one-stage item B are equal,
When the lower locking plate 21 is lowered, the lower locking plate 21 comes into contact with both sides of the pallet P. However, if the dimensions of the pallet P are larger than the external dimensions of the items B for one stage, the lower locking plate 21 21, the lower locking plate 21 will come into contact with the upper part of the pallet P. At this time, do not lower the lower locking plate 21 to prevent damage to the lower locking plate 21 and the pallet P. Similarly, when loading item B in the second and subsequent tiers, the external dimensions of the item B in the lower tier that has already been loaded are larger than the external dimensions of the item B in the 1st tier. If the size is large, when the lower locking plate 21 is lowered, the lower locking plate 21 will come into contact with the upper part of the lower item B, so in this case also, the lower locking plate 21 is not lowered and to prevent damage to item B.

In addition, when horizontally moving by the horizontal movement frame 12, as described above, when loading the first stage of items B, if the dimensions of the pallet P are larger than the external dimensions of the first stage of items B, When loading item B from the tiers onward, 1 of the lower tiers that have already been loaded
If the outer dimensions of the article B for one tier are larger than the outer dimensions of the article B for one tier, if the lower tier locking plate 21 is kept lowered, the lower tier locking plate 21
is caught on pallet P or item B, and even if the dimensions of pallet P and the external dimensions of items B in each tier are the same, if the lower tier locking plate 21 is left lowered,
Due to the shaking of each part due to movement, the lower locking plate 21
There is a high possibility that it will get caught on pallet P or item B.
Although the lower locking plate 21, the pallet P, and the article B are likely to be damaged or the pallet P may be displaced, such accidents can be prevented by raising and retracting the lower locking plate 21.

Next, the fork bodies 17 on both sides are opened to lower one stage of the items B onto the pallet P (on the second and subsequent stages, the lower items B), and the stopper plate 19 and the locking plate 20 are raised and retracted.

Furthermore, when the fork body 17 opens, since the supporting part 26 is provided with a joint part 29, the supporting part 26 is able to move the article B and the pallet P that it is supporting, as shown on the left side of FIG. By bending it along the slight gap between the two (for the second and subsequent tiers, the slight gap between the item B and the lower item B), the falling distance of the item B can be extremely reduced, and When the fork body 17 opens, the supporting member 26 rubs the supported item B or pallet P (lower item B from the second stage onwards), but the supported item B, that is, the item B to be unloaded, is not moved by the alignment plate 18. Since the pallet P below it (lower item B from the second stage onwards) is positioned by the lower locking plate 21 protruding from the lower side of the support part 26, the item B to be unloaded and the The positional relationship with the lower pallet P (the positional relationship between the item B to be unloaded from the second stage onward and the item B in the lower stage that has already been loaded on the pallet P) is maintained accurately. The loading condition does not change from the bottom shelf to the top shelf.

Next, the alignment plate 18 is opened and the lower locking plate 21 is raised and retracted.

Next, the horizontal moving frame 12 is moved to the alignment position 1, and then the elevating body 17 is lowered and the stopper plate 19 is lowered to return to the standby state.

By repeating the above-mentioned operations, the items B are loaded onto the pallet P in a predetermined stacking pattern in a predetermined number of stages, and when the loading is completed, with the horizontal movement frame 12 moved to the alignment position 1, Before the elevating body 7 is lowered, the stopper 60 for the pallet P is lowered and the pallet P is moved to the loading position 2 by the pallet conveyor 58.
It is conveyed from the roller conveyor 62 to the stopper 63.
Stop at.

Note that the article B to be loaded may be box-shaped or bag-shaped.

[Effect of idea]

As described above, according to the present invention, when the supporting part of the scooping opening/closing body is pulled out from the bottom of the held item, the item is positioned by the aligning opening/closing body, and the pallet under the held item is Since the lower stage locking body positions the items and the items to be unloaded, the positional relationship between the items to be unloaded and the pallets and items below is maintained accurately.This allows the items to be transferred stably. When used for loading goods, the upper and lower loading conditions will not be disrupted, allowing stable loading from the bottom to the top, and the lower tier locking body can be raised and retracted. By raising and retracting the lower locking body when moving the transfer cargo holding device, it is possible to prevent the lower locking body from hitting pallets or other items. It is possible to prevent accidents resulting in damage to bodies, pallets, and other items.
