Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an ingot stacking device, which facilitates the operation of stacking formed ingots so that they are easy to transport, hard to collapse, and easy to pack. This invention relates to an automatic ingot stacking device.

[Prior Art] Conventionally, molded ingots were manually stacked every 10 ingots. However, although the weight of each ingot varies slightly depending on the material, each ingot is very heavy, for example, 25 kg, and even though the ingot is solidified, it takes almost no time to solidify. Because the ingots had to be piled up before they were finished, the actual temperature of the ingots was as high as 200° to 300°, and handling them required great care and was hard work. Therefore, the work requires skill,
Moreover, there are disadvantages such as the amount that can be piled up in a day is limited, and accidents that cause back injuries to workers sometimes occur.
Work efficiency was also very poor.

Therefore, stacking devices have been manufactured and are on the market to perform this ingot stacking work mechanically instead of manually.

This stacking device was configured so that the ingots, which had been formed and transported to a proper position on a roller conveyor, were pushed by a pusher, moved to a predetermined position, and stacked.

[Problems to be Solved by the Invention] However, this stacking device had the following problems.

In other words, to ship ingots every 10 tons, arrange the appropriate number of ingots in each layer and stack them in several layers.
This is done by placing a band around it and transporting it all together.

However, in this case, in order to prevent the ingots from collapsing, it is ideal to stack them in a parallel grid shape and not make continuous cuts from the bottom to the top. In order to stack them in this manner, the movement of the pusher becomes complicated, resulting in a mechanically very large and expensive device. Moreover,
Normally, when a pusher is used to stack the ingots, the action of the pusher is simply pushing, so there is a drawback that the positions where the ingots are lined up cannot be determined accurately and the ingots tend to collapse.

On the other hand, since ingots usually have a substantially rectangular parallelepiped shape,
Every 10 pieces - When transporting items in bulk,
Since there was no space at the bottom of the bottom tier and the claws of a forklift could not fit in, the method used was to stack the ingots on a suitable platform and transport the entire platform. Therefore, such a stand for carrying out is required, and it takes time and effort to use this stand, which increases personnel costs, equipment costs, etc., which also leads to an increase in costs.

Therefore, in view of the above-mentioned points, the present invention has been developed to make it easy to transport and hard to collapse when stacking formed ingots in 10-piece ingots, and also to make it easy to pack. It was created with the aim of making it easy and automatic.

[Means for Solving the Problems] The present invention provides an even number of geta-like foot-shaped ingots whose maximum surfaces are rectangular in a ratio of 1 to 2 in length, and whose maximum surfaces are the largest of the foot-shaped ingots. A substantially rectangular flat ingot that has been molded to have the same shape as the surface and an even number times the number of foot-shaped ingots, and in the case of a foot-shaped ingot, with its teeth facing downward,
A stacking claw formed so that the foot-shaped ingots can be successively pinched and stacked; and the stacking claw is moved in a straight line when each of the ingots is clamped, and the number of foot-shaped ingots is stacked at intervals of the width of the maximum surface. The ingot can be stopped at a position equal to or less than 1, and the ingot can be held between the stacking claws as it is, and the ingot can be rotated horizontally by 90 degrees around the center of one of the long sides of the ingot's largest surface. and a pawl moving device that operates to place the ingots in a stacking position in either of the following states:
The above-mentioned problem is solved by comprising a control device that controls the stacking claws and the claw moving device so that the stacking claws can hold and release the clamping claws, and stop and rotate the stacking claws at appropriate positions.

[Operation] Hold a rectangular parallelepiped whose largest surface is a rectangle with a ratio of road width 1 to road width 2 with the claws and place it as it is, or place the rectangular parallelepiped with the center of one long side of the largest surface as the center. By rotating the claw at an angle of either 90° or 180°, the rectangular parallelepiped is moved forward and backward in the direction of movement of the claw so that its longitudinal direction is perpendicular to the direction of movement of the claw. can be moved to both sides of the moving direction so that the longitudinal direction is parallel to the moving direction. By moving this claw horizontally on a straight line, the rectangular parallelepipeds can be arranged in two rows with their longitudinal directions parallel to the direction of movement, or in two rows with their longitudinal directions perpendicular to the direction of movement. They can be arranged in combination with parallel parallelepipeds in rows.

This invention uses the above-mentioned principle and uses stacked claws to
In the bottom row, geta-shaped foot-shaped ingots are arranged in two rows so that the longitudinal direction of the largest surface is parallel to the moving direction of the stacked claws. Ingots are arranged in the same way as foot-shaped ingots, and flat ingots are placed in parallel in two rows, with the longitudinal direction of the largest surface being perpendicular to the direction of movement of the stacking claws. This work is automatically performed by stacking the patterns in a substantially parallel grid pattern by stacking them alternately.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

That is, the reference numeral 1 shown in the figure is an ingot stacking device, and as shown in FIG. The foot-shaped ingot 2 and the flat-shaped ingot 3 to be formed are piled up. The foot-shaped ingots 2 are in the shape of a clog whose largest surface is a rectangle with a length of 2 in proportion to the road width of 1, and an even number of the ingots are successively molded.

Moreover, the flat ingot 3 is a substantially rectangular parallelepiped whose largest surface is the same shape as the largest surface of the foot-shaped ingot 2, and is actually trapezoidal because it has a draft angle during casting. It is formed continuously by an even number times the number of .

The stacking claws 10 include a clamping claw 11 in which two plates with approximately wedge-shaped tips are arranged vertically in parallel, and a fixed clamping claw 11 in which four plates of the same shape are arranged vertically in parallel facing the clamping claw 11. It is formed from a pawl 12 and a hydraulic cylinder 14 that operates the clamping pawl 11 via a lever 13. Moreover, this stacked nail 10
An inversion claw 15 is provided near the stacking claw 10, which is formed by arranging two plates of the same shape as the stacking claw 10 and facing each other in parallel.
When stacking flat ingots 3, only the foot-shaped ingots 2 are held and turned over.

The reversing claws 15 that clamp the foot-shaped ingot 2 have the structure as described above, but after gripping the foot-shaped ingot 2, the reversing claws 15 lift it slightly and move it horizontally to a position where the foot-shaped ingot 2 can be reversed. , At that position, foot-shaped ingot 2
The function is to reverse the object and move it back to its original position. The operation of lifting the foot-shaped ingot 2 is as follows:
This is done by raising the reversing claw 15 together with the reversing movement device 17 using a hydraulic cylinder 18. The horizontal movement of the reversing claw 15 is performed by a reversing movement device 17 that horizontally moves by rotating a threaded rod 16. The reversing claw 15 is reversed by a motor (not shown) built in the reversing movement device 17 or the like. Note that reference numerals 19 in the figure indicate two guides for horizontally moving the reversing and moving device 17. Further, it goes without saying that the reversing movement of the reversing claw 15 is not limited to the means described above.

On the other hand, the claw moving device 20 includes a claw rotating device 21 that rotates the stacked claws 10 horizontally, and a claw rotating device 21 that rotates the stacked claws 10 horizontally.
, a horizontal movement device 23 that moves both the pawl rotating device 21 and the lifting device 22 in the horizontal direction, and the hydraulic cylinders 14, 18. It consists of an oil sending mechanism 24 that sends compressed oil to.

The claw rotation device 21 rotates the stacking claws 1 with the horizontal midpoint of the fixed claws 12 of the stacking claws 10 as the center.
The drive shaft of the built-in motor (
(not shown) is connected to the stacking claw 10 via a connector 25.

Further, the lifting device 22 lifts and lowers the pawl rotating device 21 by rotating a threaded rod 26.
The claw rotating device 21 is moved along the guide rod 27 of the book.

The horizontal movement device 23 consists of two horizontal beams 29. of the portal frame 28.
A triangular mountain-shaped rail 30 is formed by placing and fixing a uniformly transparent shaped steel on 29 so that the intermediate corner of its cross-sectional shape protrudes upward. It consists of a truck 31 and a truck tensioning device 33 that pulls the truck 31 using a wire 32 that revolves around the truck 31 using the driving force of a motor.

The trolley tensioning device 33 is stopped at a predetermined position by a stopper 34 made up of a plurality of limit switches that are movably attached to the side surface of the horizontal beam 29. , the number of positions is the number of foot-shaped ingots 2 minus 1 at intervals equal to the width of the maximum surface of each ingot 2.3.

Furthermore, the oil feed mechanism 24 includes an oil feed pipe 35, one end of which is connected to a reinforcing holder 37 attached near the upper part of the guide rod 27, and a hydraulic pressure for sending compressed oil to the oil feed pipe 35, although not shown. Although not shown, piping is appropriately arranged to send compressed oil from the oil pipe 35 to each of the hydraulic cylinders 14, 18, etc.

It should be noted that the above-mentioned lifting device 22, horizontal movement device 23, trolley tension device 33, and stopper 34 are not limited to the structures described above, and may have other structures as long as they perform the same function. Needless to say. Also, stopper 3
4 may be used instead, the horizontal moving device 23 may be driven by a servo motor or the like, and the servo motor may be appropriately controlled to stop the horizontal moving device 23 at the aforementioned position.

The stacking device 1 formed in this manner is appropriately controlled by a control device 36 including, for example, a device having a sequence circuit or a computer.

As shown in FIG. 2, this stacking device 1 has the following features:
It is used by being incorporated into the ingot manufacturing apparatus 40.

This ingot manufacturing apparatus 40 includes a holding furnace 42, an ingot continuous caster 11143, an ingot conveyor 44, and an ingot discharge conveyor 45.

Molten metal, such as molten zinc, in the holding furnace 42 is poured into the ingot case 48 of the continuous ingot caster 1143 by the pourer 47.

This ingot continuous caster 43 has a rotating belt-shaped body 49.
The ingot cases 48 for the foot-shaped ingots 2 are successively installed in the number of foot-shaped ingots 2 to be manufactured, and then the ingot cases 48 for the flat-type ingots 3 are successively installed in the number of the flat-type ingots 3 to be manufactured. It has a structure that is installed with Then, the molten zinc poured into the ingot cases 48 solidifies while the strip 49 goes around, and as each ingot case 48 reverses to go around, it is transferred onto one roller 51 of an ingot lift device 50, which will be described later. They are taken out sequentially.

The foot-shaped ingot 2 and flat-shaped ingot 3 taken out in this way are lifted to the position of the ingot conveyor 44 by the ingot lift device 50.

As shown in FIGS. 3 and 4, this ingot lift device 50 is designed to move ingots 2.
The bottom plate on which the ingots 3 are placed is a single roller 51, and this single roller 51 is formed so as to rise to the position of the ingot conveyor 44.

The structure is such that the loading platform 52 is fixed to something such as a chain 53 that revolves in the vertical direction, and the loading platform 52 is raised and lowered by moving the chain 53 around in the vertical direction. In addition, when the loading platform 52 is positioned downward, the ingots 2.3 are taken out from the continuous ingot casting 1143, but at that time, the two roller pedestals 41 are diagonally inserted between each roller of the one roller 51. Make it stand out,
When the ingot 2.3 is dropped and placed on this roller holder 41, one roller 5 is moved by the roller of the roller holder 41.
1 to a predetermined position. Furthermore, this ingot lift device 50 is provided with a butcher 54, and each ingot placed on one roller 51 is transferred to the ingot conveyor 44 by one roller 51.
up to the position.

It is formed so as to be pushed out in the direction of this ingot transport conveyor 44 when raised.

On the other hand, each of the ingots 2 and 3 pushed out onto the ingot transport conveyor 44 is moved to an ingot holding position 55 on the ingot transport conveyor 44 by the transport force of the ingot transport conveyor 44.

Each ingot 2 moved to this ingot clamping position 55
．． 3 are sequentially stacked on the stacking position 5 of the ingot delivery conveyor 45 by the stacking device 1. Each ingot 2.3 stacked in a predetermined amount in this manner is moved by the conveying force of the ingot carry-out conveyor 45 to a carry-out position 7 of the ingot carry-out conveyor 45, and is carried out to the outside by a forklift 56 at that position. .

In that case, each ingot 2.
3 is accumulated as follows.

That is, as an example, a case will be described in which a total of 40 pieces, 4 pieces of foot-shaped ingots 2 and 36 pieces of flat-shaped ingots 3, are piled up. In this case, a good separation would be to set the weight of each ingot 2.3 to 25; and t to be 10 to 1 ton. At that time, the ingots 2.3 moved on the ingot conveyor 44 to the ingot clamping position 55.
is such that its longitudinal direction is the same as the direction of movement, and
The moving direction of the stacking claw 10 should be the same as that of the stacking claw 10, and the ingot 2.3 should be moved in the same state as it is.
It is designed so that it can be held and conveyed at 0.

Each ingot 2 moved sequentially to the ingot clamping position 55
, 3 are sequentially held by the stacking claws 10, but only in the case of the foot-shaped ingot 2, due to manufacturing considerations, that is, the production of the ingot case 48 and the draft angle, the ingots are transferred from the continuous ingot casting machine 43 to the ingot conveyor 4.
When it is turned over and taken out, the teeth 4 are facing upward.

Therefore, first, before the foot-shaped ingot 2 is clamped by the clamping claws 11 and the fixed claws 12, the foot-shaped ingot 2 is reversed by the reversing claws 15 and placed again at the ingot clamping position 55 with the teeth 4 facing downward.

The foot-shaped ingots 2 that have been sequentially reversed in this manner are sequentially arranged at the stacking position 5 of the ingot conveyor 44 by the stacking claws 10.

The arrangement state and process are as follows.

In other words, as shown in the left end of FIG.
It is carried in a pinch by 0.

At that time, 10 is left as it is without being rotated. In this way, the foot-shaped ingot 2 is placed with one long side positioned on the line of movement of the stacking claws 10.

Next, as shown in the second part of FIG. It is moved 1806 times to the left in the direction and placed.

Then, this foot-shaped ingot 2 and the first foot-shaped ingot 2 are arranged with their long sides facing each other and in contact with each other.

Furthermore, the third foot-shaped ingot 2 is 3 in Fig. 5 (A).
As shown in No. 2, among the respective stop positions 6 by the stacking claw 10, a position one position apart from the first stop position 6,
That is, since there are four foot-shaped ingots 2, there are three stopping positions 6, and the foot-shaped ingots 2 are moved to the stopping position 6 at the opposite end to the initial position. Then, at that position, the stacked nail 1
Place foot-shaped ingot 2 without rotating 0. Then, since the interval between the stop positions 6 is the width dimension of each ingot 2 and 3 at the maximum surface, that is, 172 mm of the long side, the ingots 2 and 3 come into contact with the short side of the maximum surface of the foot-shaped ingot 2 placed first, and are stacked. They are arranged so that their long sides are located on the line of movement of the claws 10.

The fourth foot-shaped ingot 2 has long sides that are similar to the third foot-shaped ingot 2, as shown in the fourth part of FIG. 5(A). face to face contact,
In addition, the second foot-shaped ingots 2 are arranged with their short sides facing each other and in contact with each other.

The foot-shaped ingots 2 arranged in this way are arranged so that the teeth 4 face downward and the rectangular sides of the largest surfaces form two rows with their long sides facing each other, as shown in FIG. 6(A). It becomes an array with .

Next, the 36 flat ingots 3 are made into foot-shaped ingots by alternating stages whose largest surfaces are in the same arrangement as the foot-shaped ingots 2 and stages that are approximately parallel to this stage. Stack on top of 2.

This latter stage is arranged as follows.

That is, first of all, the left end of FIG. 5(B), that is,
As shown in the first figure, the first flat ingot 3 is 1
Among the stop positions 6 lined up in a row, the stop position 6 at one end
The piling claws 10 hold and move the stack up to
Stack the claws 1 so that they are on the outside of the row of stop positions 6.
0 is rotated 90 degrees horizontally. Then, the flat ingot 3 is arranged so that the long side of the largest surface is perpendicular to the moving direction of the stacking claw 10.

Next, the second flat ingot 3 is
As shown in No. 2, the stacking claw 10 is stopped at a stop position 6 adjacent to the stop position 6 at the one end, and at that time, the stacking claw 10 is left as it is without being rotated. Then, the short side of this flat ingot 3 comes into contact with the long side of the first flat ingot 3,
Moreover, the long sides are arranged so as to be located on the movement line of the stacking claws 10.

Then, the third flat ingot 3 is placed on the left side with respect to the direction of movement of the stacking claw 10 at the same position as the second flat ingot 3, as shown in the third part of FIG. 5(B). Alternatively, rotate it 180 degrees to the right and place it in that position. Then, this third flat ingot 3 has its short side facing and in contact with the long side of the first flat ingot 3, and its long side is located on the movement line of the stacking claw 10, and both the second flat ingot 3 The flat ingot 3 is placed so as to face and come into contact with the long sides of the flat ingot 3.

Furthermore, the fourth flat ingot 3 is 4 in Fig. 5 (B).
As shown in the figure, the stacking claw 10 is stopped at the stop position 6 located at the opposite end of the first flat ingot 3, and the flat ingot 3 is located on the opposite side to the arrangement of the stop positions 6. Rotate the stacking claw 10 by 90 degrees as shown in FIG. That is, the flat ingot 3 is arranged symmetrically on the completely opposite side to the first flat ingot 3. Then, the fourth flat ingot 3 is arranged with its long side perpendicular to the direction of movement of the stacking claws 10 and in contact with the short sides of the second and third ingots. The Rukoto.

As a result, as shown in FIGS. 6(A) to 6(E), the flat ingots 3 arranged in this manner are placed in the same arrangement as the foot-shaped ingots 2 or in a similar arrangement to this arrangement. When stacked on top of the mold ingot 3, they are stacked in a substantially parallel grid shape. If the flat ingots 3 are stacked alternately in this manner, there will be no continuous break from the bottom to the top, making it possible to stack the flat ingots 3 in a very strong and resistant state.

In addition, in this case, when the number of stacked tiers is an even number, the arrangement of the foot-shaped ingots 2 on the top tier is not the same as the arrangement of the foot-shaped ingots 2 on the bottom tier, and it is difficult to hang the band 8, which will be described later.
The flat ingot 3 in the next stage is replaced with this foot-shaped ingot 2.
They should be arranged in the same order as the above, and stacked on top of that one after another. If the number of stacked stages is odd,
They can be stacked alternately from the bottom to the top. In other words, the arrangement at the bottom and the arrangement at the top may be the same.

As described above, all operations of the stacking claws 10 are controlled by the control device 36. The structure of this control device 36 is not particularly limited. However, there are general ones that have a sequence circuit or are made up of an arithmetic device such as a computer, and if these are used, the above-mentioned operations can be easily controlled. In addition, at this time, the clamping, transportation, and positioning of each ingot 2.3 are all performed by signals from sensors (not shown), and the types of sensors include magnetic sensors, optical sensors, contact sensors, etc. Commonly used.

The ingots 2.3 thus stacked in the stacking position [5] are moved to the discharge position 7 by the ingot discharge conveyor 45. At that position, as shown in FIG. 7, the band 8 is hung so that it does not collapse, and the lifting claw 57 of the forklift 56 is inserted into the gap created by the teeth 4 of the foot-shaped inbot 2. It is something that you put in, lift up and take out.

The arrangement pattern is the above-mentioned pattern when stacking 4 sheets at a time, but when stacking 6 sheets at a time, the pattern shown in Figure 8 can be repeated alternately. That's fine.

At this time, in order to adapt to all numbers of sheets,
First, the stacking claws 10 are moved in a straight line and can be stopped at positions equal to the number of foot-shaped ingots 2 minus 1 at intervals equal to the width of the maximum surface of each ingot 2. .3 is formed so as to be horizontally rotatable around the center of one long side of the largest surface when held between the two sides;
Using the stacking claw 10, first stack the successively formed foot-shaped ingots 2 with the teeth 4 facing downward and at every other position from one end position at the stop position of the stacking claw 10. The claw 1o is operated by combining the state in which it is not rotated and the state in which it is rotated 180' to the left or right with respect to the direction of movement, so that the longitudinal direction of the largest surface is relative to the direction of movement of the stacking claw 10. A stage in which the successively formed flat ingots 3 are arranged in two parallel rows, and then piled up in the same position as the foot-shaped ingots 2 and arranged by rotating the claws. Then, the stacking claws 10 are stopped at both ends of the stop position 6 of the stacking claws 10, at the positions next to these, and at positions spaced apart from the next positions, and at the stop positions 6 at both ends, The stacking claws 10 are rotated by 90 degrees so that the flat ingots 3 are arranged on the outside, and at the other stop positions 6, the stacking claws 10 are left as they are without being rotated, and left or right with respect to the moving direction. 1
It is operated in combination with the state rotated by 80 degrees, and like the foot-shaped ingot 2, the longitudinal direction of the largest surface is the stacked claw 10.
If the rows are arranged in two consecutive rows parallel to the direction of movement of the ingots, and the rows are stacked alternately, and the top row is a row that is arranged in the same way as the foot-shaped ingot 2, can be piled up.

[Effect 1 of the Invention] The present invention configured as described above includes an even number of geta-shaped foot-shaped ingots 2 whose largest surfaces are rectangular with a ratio of approximately 1 width to 2 lengths; In the case of the foot-shaped ingot 2, a flat ingot 3 of a substantially rectangular parallelepiped shaped to have the same shape as the largest surface of the foot-shaped ingot 2 and an even number times the number of the foot-shaped ingots 2 is made into a foot-shaped ingot with its teeth 4 facing downward. The stacking claws 10 are formed to be able to be stacked by sequentially holding and stacking the ingots 2 and 2, and the stacking claws 10 are moved in a straight line when each of the ingots 2. It is possible to stop at a position equal to the number of ingots 2 minus 1, and the stacking claws 10 hold the ingots 2.3 as they are, and the ingots 2.3
90″ horizontally centered on the center of one long side of the largest surface of
A claw moving device 20 that operates to place the ingots 2.3 in a stacking position in either a rotated state or a 180° rotated state, and a claw moving device 20 that operates to place the ingots 2.3 in a stacking position in either a rotated state or a 180° rotated state; The stacking claw 10 and the control device 36 that controls the claw moving device 20 are configured to stop and rotate the stacking claws at appropriate positions, so the structure is simplified and the stacking work can be performed accurately. .

Then, an even number of clog-shaped foot-shaped ingots 2, each of which has a rectangular maximum surface with a width of approximately 1 and a length of 2, are formed in succession, so that the maximum surface has the same shape as the maximum surface of the foot-shaped ingot 2. If the approximately rectangular parallelepiped flat ingots 3 are continuously molded by an even number times the number of foot-shaped ingots 2, all the foot-shaped ingots 2 can be arranged in the bottom row, and an appropriate number of flat ingots 3 can be stacked on top of it. I can do it. Moreover, when stacking, even if each ingot is stacked vertically and horizontally, the maximum surface length is 2.
Since the width is a ratio of 1, the outer diameter of the entire row can be a rectangle with the same shape for each row. This allows them to remain stable when stacked.

Moreover, first, the foot-shaped ingot 2, which was sequentially formed,
-4 facing downward, and at every other position from one end of the stop position of the stacking claws 10, the stacking claws 10 can be left as they are without being rotated, or moved to the left or right with respect to the moving direction. The flat ingots 3 that have been sequentially formed are stacked in the same position as the foot-shaped ingots 2, and the claws are rotated and arranged. , both ends of the stacking claw 1o at the stop position 6, and the positions next to them;
Then stack nails 1 at every other position from this next position.
0, respectively, and at the stop positions 6 at both ends, the stacking claws 10 are rotated 90 degrees so that the flat ingots 3 are arranged outside of the arrangement of the stop positions 6, and at the other stop positions 6, the stacking claws 10 are rotated by 90 degrees. , as it is without being rotated, and 180 degrees to the left or right with respect to the direction of movement.
``''The ingots are operated in combination with the rotated state, and similarly to the foot-shaped ingots 2, the ingots are continuously arranged in two rows with the longitudinal direction of the largest surface parallel to the moving direction of the stacking claws 10. If the steps are stacked alternately, and the top step is arranged in the same way as foot-shaped ingot 2, the work of automatically stacking ingots 2 and 3 in a parallel grid pattern can be done only in a straight line. This can be done by moving the stacking claws 10, and the structure of the stacking claws 10 can be greatly simplified.

Furthermore, during the straight-line movement, the operation of the stacking claws 10 at each stop position 6 is very simple as the stacking claws 10 are simply rotated horizontally, so the structure of the device can be further simplified. At the same time, the ingots 2.3 stacked in this manner can be stacked in a stable manner with almost no displacement as described above. the result,
When trying to automate the stacking work of the main ingots, it can be done easily, and at the same time, the stacking work can be done accurately, so it is difficult to collapse and easily during packaging. I can do it.

Moreover, it can be easily incorporated into ingot manufacturing equipment, and can be easily automated together with the equipment. Therefore, stacking and packing of ingots can be automatically performed without bothering the operator.

Further, since it has the above-described structure, it can be miniaturized, and even if it is incorporated into an ingot manufacturing apparatus, it does not take up much space, so it is very easy to use.

As explained above, according to the present invention, when stacking ingots, it is possible to easily transport and prevent them from shifting, and also to make them easy to pack. In addition, it has various excellent effects such as minimizing capital investment and maximizing cumulative effect.
