Description

[Detailed description of the invention]

With this invention, several ingots were arranged in a warehouse.
This is related to the automatic stacking of ingots next to IC 1lf while preventing k. Conventionally, this 0IIO loading mlX% ingot gripping machine
The KIi point is 69, and the ingots are stacked one after the other, but a lIfM interval occurs during stacking of the aligned ingots, and the load collapses during transportation after packing.

[Due to the risk of
One accident occurred during land transportation. The ir1 and 2 diagrams show the conventional horizontal attachment machine and gripping machine W.
t indicates Tog, l is the gripping mechanism main body, 2 is a gripping part weird below it, and this gripping WARα left and right #
It has a movable claw 3 that closes the cll. This movable claw 3 grips raze upper 10 cylinder number fcxg
The fixed claws j4 and 3b are provided in upper and lower stages at a predetermined distance between the lower end of the movable claw and the vicinity #C of the lower end of the movable claw. vc
α fixed roller 5 is assigned. In the figure, 6 is a cylinder that is rotated by 90 degrees to the stile grip IH2, 8 is an ingot that is loaded first, and an ingot that is loaded after SAA. The conventional horizontal stacking machine configured as I5 above cannot perform stable stacking due to the contact with the fixed rollers 5 during the second stage horizontal stacking. In addition, there is a drawback that a gap is generated in the later loading inlet (8a) due to the shock caused by the cylinder 6 turning 90' or by the movement of the clamping unit 1. That is, to explain the above conventional operation, the fixed claw 3a
Since the fixed roller 5t is placed below the first layer of pre-laid 4 ingots) 80, the second layer of post-laid ingots) 85
When stacking Lk, the fixed roller S comes into contact with the first stage ingot 8. Therefore, when loading ingot tubes in the second stage, 1. −・Fixed roller 5 between the first stage ingots
With a gap (2) of the thickness of the diameter glass fixing claw 3a plus a created, the ingot 81t-H is opened by the gripper 5i21-cylinder 4 and dropped from the height of the later stacked ingot 81t-H. Here, the aO dimension is usually H50~10 G111, and if it is dropped from such a height, it will bounce after colliding with the first stacked ingot 8, and the alignment 1 of the second stacked ingot 8a will collapse fL, and there will be l111 between them. arise. This state t sono i\
If the cargo is unloaded and loaded one after another in a container, the cargo will become unstable and there is a danger that the cargo may collapse during transportation. There, in the gap between each other where the alignment was broken. When stacking ingots afterward, as shown in Figure 2-1, the amm crawler KXD width adjustment is carried out, but it is not possible to completely remove *Mk. Further, even if the weight of the ingot varies within the standard tolerance range d, the dimensions of each ingot will be uneven. Therefore, even if it is clamped with the gripping part 2, it is completely clamped and fixed within one row of alignment? When the ingot is placed on top of the fixed claws 3a, 3a and 3b, it cannot be held between the grips 112 and is in a slanted state. In these two conditions, there were drawbacks such as a gap being created due to the shock caused by the cylinder 6KX90' turning operation, the movement of the gripper body Ig), etc., leading to cargo collapse. This invention was made in view of the above-mentioned circumstances.
), the footer is improved to hold the ingot from above and from above, prevent the occurrence of a break due to shock, eliminate the bounce of each ingot released from the footer, and reduce the falling distance of the released ingot, i.e. To provide an automatic ingot stacking machine which has a small height t and is aimed at preventing cargo collapse by stacking ingots in an orderly and dense layer. Hereinafter, the third to sixth embodiments of the present invention will be explained differently. 3rd wJ is the overall ingot loading machine 11 according to the present invention.
10t: [Previous process In addition, it is an elevating cylinder for carrying out and stacking ingot groups one block at a time from the alignment section 12 in the 12th frame. It is being The movement of this hook 17 is the cross-feeding cylinder 14 mounted on the VC frame 13 and the elevating cylinder izcx9X axis,
It is X5flC which moves in two directions in the Y-axis direction. In addition, a cylinder 18KX mounted on the upper part of the hook 1d serves as the main part of the movable claw 19 which opens and closes, and a pressing claw 21t which moves up and down with the cylinder 2G. On the other hand, at the lower end of the movable claw 190, there are ingots that have already been stacked! A detection claw 22 is provided for detecting the presence or absence of the ingot 110 and detecting the upper surface of the ingot 110 to be stacked thereon. In the figure, 23 is the cylinder for rotating the hook 17't9G', and 24 is the ingot 1 for loading a predetermined amount.
107a It is a conveyor for ivy group t-*a. 1I4- shows the main structure of the 3rd edition, and the 5th-
In summary, the following is an explanation of the operation state of the detection claw 22 and the striker 25 provided for performing the operation. First of all, the first row of inbots) 11 are all inverted trapezoidal vcm
Since they are stacked naturally, even if the downward side comes into contact with Jinbea 24#C, there is nothing suspicious about the detection claw 22 and roller zsrx, so it can be opened smoothly. On the other hand, the second stage and subsequent steps) 111'! The ingot 11 [clamped detection claw 22
The rollers 26 are sandwiched between the first stage ingot 11 and the second stage ingot 11 as shown in FIG. 5(a). In this state, move the movable claw 19[-WIa and detect the detection claw 22[J].
When the ingot 11 is released, the ingot lIr1
As a result, the detection claw 22 has a height x equal to the thickness of the roller 26.
9. The roller 26 rotates to prevent the sudden fall and disturb the alignment of WAt.
5, and the rotation is performed so that each of the left and right rollers (Xf) comes into contact with the other portion of the roller 27. The roller 27 contacts the side taper of the ingots 11 in the second and subsequent stages at z5 shown in Figure i@6, rotates as a guide, and strongly presses the stacked ingots 11. . Further, the roller 27 is at approximately the same level as the conveyor 24, and is guided to rotate by coming into contact with the striker 25. By the way, this striker 25 has one X on cylinder 28.
It is designed to expand and contract only in the axial direction, and the rotation of this expansion is
There's Natsu'C. Note that this is only the case where the second stage ingots 11 are stacked on the extension of the striker 2S. - In this striker 250 operation [including each go pneumatic, hydraulic and electrical control circuit 01i! Omit the clear frame. Next, the operation of the ingot stacking machine according to the present invention, which is #cWliL as described above, will be explained in detail. First, the painter 5xJI was sent, and the ingot 11 was withdrawn.
In the reversal alignment sio, the ingots are selected to be in that state and reversed, and they alternately turn and avoid them in an orderly manner. The ingots 11 that have been packed in a predetermined amount are then suspended by the gripping mechanism's seven clamps (17 KJ) and stretched directly above the shipping conveyor 24, where they are stacked in a cross-shaped pattern by changing the direction 90' in the first and second stages. Tei〈0. jl, 1 At this time, aligned ingot 1lt-z to hook 11
Since the ingot II#:f cylinder 20 descends when the cylinder 12rcx moves up, the pressing claw 21KX and the detection claw 22#C are pressed and fixed. Therefore, the ingots 11 will not be disturbed due to shocks or the like. On the other hand, the ingots 11 are held on the conveyor 24 by the clamps 17 and are conveyed in a state of being suppressed by the pressing claws 21 and the detection claws 22. Without seeing the operation of the first stile rods 26, it is quietly placed on the conveyor 24 with zero fall.The second tier is the first tier ingots (11) stacked in an inverted trapezoidal state, so the 7 ivy 17 is the highest. If the lower limit [1] is lowered, the detection claw 22 and D-ra 26 that are holding the ingot ll' will not be able to smoothly pull out the claw t9 between the upper surface of the first stage ingot 11 and the downward direction of the second stage ingot ll. Therefore, as shown in 1gsw (a), the second stage invoice) 1
1 stowage is sometimes carried out by the downward movement of 17. The striker 25 extends in synchronization with the downward movement of 17 and guides it to the roller 27'. For this purpose, the roller 26 rotates and the upper and lower invoices are moved as shown in No. 5-(b). 11t) H. Therefore, as the 7 ivy 17 continues to descend, the second stage ingot 1lk approaches the top of the first stage ingot 11. When the detection claw 22 comes into contact with the first stage ingot llIc, After cylinder 12 is stopped, move cylinder 1 to movable claw 19'.
8WCX is designed to narrow the falling interval and then release the second stage ingot. Further, the movable claw 1G is released when pressed in parallel with the movable member 8+. When the movable claw 19 is released, the stage WA is stacked on the xl, so the head difference in this case is almost zero, so a collision like bouncing ↑X does not occur, and the falling ingot l
Since it falls while being pressed by the lα pressing claws 21, the above-mentioned bounce does not occur at all. Therefore, the second stage ingot 11 [-] is not produced;
It is stacked in an orderly manner. Next, Inbo Th after the third role
When stacking, as shown in Fig. (c), as the striker 25 is reduced, the movable claw 19 moves away from the inboard (in which loading has been completed) and rises, and then repeats the movement n.
4, which is done by adding 2 to i, and the side taper %L of the trapezoidal third stage ingot 11 as shown in the 6th WIJK.
When the side taber/LWC is facing upward, the roller 26 comes into contact with the roller 26, and as a result of applying strong pressure to the guide, the detection claw 22'' is separated from the gap between the two ingots.
ffi, there is no difference in height between the second and third ingots 11. Furthermore, the third and subsequent stages of stowage in the same condition are processed. In this case as well, the pressing pawl 21 operates in the same manner and produces the same results as described above. x 5 FCs explained above via via This invention VCX
The automatic ingot stacking device can automatically stack ingots without creating a gap between the stacked ingots. For this reason, there is a need for transportation and transport.
It can be transported and transported extremely safely without causing any damage.
