Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an ingot stacking device,
To provide an ingot stacking device capable of easily and automatically stacking molded ingots so that they are easy to transport, hard to collapse, and easy to pack.

[Prior Art] Conventionally, molded ingots have been manually stacked one lot at a time. However, ingots vary slightly depending on the material they are made of,
The weight of each ingot is very heavy, for example 25 kg, and even though the ingots are solidified, they must be piled up almost immediately after solidification, so the actual weight of the ingots is The temperature was high, around 200° to 300°, and handling required great care and was hard work. Therefore, the work requires skill, the amount that can be piled up in a day is limited, and there are disadvantages such as accidents that sometimes cause workers to hurt their backs, etc. Moreover, work efficiency is very poor. It was.

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 constructed so that the formed ingots were transported to a proper position by a roller conveyor or the like, and were pushed by a pusher or the like to move the ingots to a predetermined position and stack them.

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

That is, to ship ingots in batches, a suitable number of ingots are arranged in each row, stacked in several rows to form one lot, and the ingots are tied with a band and transported as a whole.

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 like a lever, the movement of the pusher becomes complicated, resulting in a very large and expensive device mechanically. Moreover, when a pusher is used to pile up the ingots, the action of the pusher is simply pushing, so the ingots cannot be placed in precise positions, making them prone to collapse.

On the other hand, since ingots usually have a substantially rectangular parallelepiped shape, when carrying out a batch of ingots, it is necessary to use an appropriate stand because there is no gap at the bottom of the bottom stage and the claws of a forklift cannot fit in. The method used was to stack ingots on top and transport the entire platform. Therefore, such a table for carrying out is required, and it takes time and effort to use this table, which increases personnel costs, equipment costs, etc., which also leads to an increase in costs.

Therefore, in view of the above-mentioned points, this invention makes it easy to transport and hard to collapse when stacking molded ingots one lot at a time, 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 with a ratio of approximately 1 width to 2 lengths, and a maximum surface of the foot-shaped ingots. Approximately rectangular parallelepiped flat ingots that have the same shape as the surface and are molded an appropriate number of times the number of foot-shaped ingots are sandwiched and stacked one after another, starting with the foot-shaped ingots, with the teeth facing downward in the case of foot-shaped ingots. When each ingot is held between the stacking claws, the stacking claws are moved in a straight line, and at intervals equal to the width of the maximum surface, one foot-shaped ingot is removed from the number of foot-shaped ingots.
The ingot can be stopped at a position equal to the number of positions subtracted by , and the stacking claws can hold the ingot as it is, rotate 90 degrees horizontally around the center of one long side of the largest surface of the ingot, and rotate the ingot horizontally by 180 degrees.゜A claw moving device that operates to place the ingots in a stacking position in either the rotated state, and a claw moving device that allows the stacking claws to hold and release the ingots, and to stop the stacking claws from moving and rotate them at the appropriate position. In order to solve the above-mentioned problems, the present invention is composed of a stacking claw and a control device for controlling the claw moving device.

[Operation] A rectangular parallelepiped whose largest surface is a rectangle with a width of approximately 1 and a length of 2 is held between the nails and left as is, or the center of the rectangular parallelepiped is centered at the center of one long side of the largest surface of the rectangular parallelepiped. 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, and , 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 in one direction, the rectangular parallelepiped can be arranged in two rows with the longitudinal direction parallel to the direction of movement, or with the rectangular parallelepiped placed in a direction perpendicular to the direction of movement. They can be arranged in combination with rectangular parallelepipeds placed in two rows in parallel.

This invention uses the above-mentioned principle to create a geta-shaped foot-shaped ingot at the lowest level using stacking claws.
The ingots are arranged in two rows so that the longitudinal direction of the largest surface is parallel to the direction of movement of the stacked claws, and on top of the foot-shaped ingots, flat ingots having a substantially rectangular parallelepiped shape are arranged in the same manner as the foot-shaped ingots. and flat ingots placed in a direction perpendicular to the longitudinal direction of the largest surface with respect to the direction of movement of the stacking claws, and flat ingots placed in parallel in two rows. By stacking them, they are stacked in a roughly parallel grid pattern, and this process is performed automatically.

Reversing claws 15 are provided which are formed by arranging two plates of the same shape as the stacking claws 10 and facing each other in parallel. To,
It is formed so that only the foot-shaped ingot 2 can be held and turned over.

The reversing claws 15 that hold the foot-shaped ingot 2 have the above-mentioned structure, 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, the foot-shaped ingot 2 is reversed and moved to its original position again. The operation of lifting the foot-shaped ingot 2 is carried out by raising the reversing claw 15 together with the reversing movement device 17 by means of a hydraulic cylinder 18. The horizontal movement of the reversing claw 15 is performed using the threaded rod 16.
Reversing movement device 1 that moves horizontally by rotating
Do this according to step 7. 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 pawl moving device 20 includes a pawl rotating device 21 that horizontally rotates the stacking pawls 10, a lifting device 22 that raises and lowers the pawl rotating device 21, and a pawl rotating device 21 and the lifting device 22 that It consists of a horizontal movement device 23 that moves horizontally, and an oil feed mechanism 24 that sends compressed oil to the hydraulic cylinders 14 and 18.

The pawl rotation device 21 rotates the fixed pawl 1 of the stacking pawl 10.
The drive shaft (not shown) of the built-in motor is connected to the connecting tool 25 so that the stacking claw 10 is rotated about the horizontal midpoint position of 2.
It has a structure in which it is connected to the stacking claw 10 via.

Further, the lifting device 22 lifts and lowers the pawl rotating device 21 by rotating a threaded rod 26,
At that time, the pawl rotating device 21 is moved along the two guide rods 27.

The horizontal movement device 23 is a triangular mountain-shaped rail formed by placing and fixing equilateral angle steel on the two horizontal beams 29, 29 of the portal frame 28 so that the intermediate angle of the cross-sectional shape projects upward. 30, and a trolley 31 that is attached to the lifting device 22 and moves on the rail 30.
and a truck tensioning device 33 that pulls the truck 31 by a wire 23 that goes around it using the driving force of a motor.

In addition, the above-mentioned lifting device 22 and horizontal movement device 2
3. It goes without saying that the truck tensioning device 33 and the stopper 34 are not limited to the structures described above, and may have other structures as long as they perform the same function. Alternatively, the horizontal moving device 23 may be driven by a servo motor or the like without using the stopper 34, 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.

This stacking device 1 is used by being incorporated into an ingot manufacturing device 40, as shown in FIG.

This ingot manufacturing apparatus 40 includes a holding furnace 42,
It consists of an ingot continuous caster 43, an ingot conveyor 44, and an ingot discharge conveyor 45.

Molten metal, such as molten zinc, in the holding furnace 42 is poured into an ingot case 48 of an ingot continuous caster 43 by a pouring machine 47.

This continuous ingot casting machine 43 successively attaches as many ingot cases 48 for the foot-shaped ingots 2 to the circulating strip 49 as the number of foot-shaped ingots 2 to be produced, and then ingot cases 48 for the flat ingots 3 to be manufactured. It has a structure in which ingot cases 48 are successively attached as many as the number of flat ingots 3 to be manufactured. 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 to the roller stand 5 of the ingot lift device 50, which will be described later.
1 and sequentially taken out.

The foot-shaped ingot 2 and the flat-shaped ingot 3 taken out in this way are transferred to an ingot lift device 5.
0 to the position of the ingot transport conveyor 44.

As shown in FIGS. 3 and 4, this ingot lift device 50 moves the bottom plate of a loading platform 52 having a substantially L-shaped cross section on which the ingots 2 and 3 are placed onto a roller platform 5.
1, and this roller stand 51 is formed so as to rise to the position of the ingot conveyor 44.

Its structure consists of a chain 53 that revolves in the vertical direction.
The loading platform 52 is fixed to something like this, and the loading platform 52 is raised and lowered by moving this chain 53 around in the vertical direction. Furthermore, when the loading platform 52 is positioned downward, the ingots 2 and 3 are taken out from the continuous ingot casting machine 43, but at that time, the two roller supports 41 are diagonally inserted between the rollers of the roller platform 51. When the ingots 2 and 3 are dropped and placed on this roller pedestal 41, they are moved to a predetermined position on the roller pedestal 51 by the rollers of the roller pedestal 41. Furthermore, this ingot lift device 50 is provided with a pusher 54, which moves each ingot placed on the roller table 51 to the ingot conveyor 44 when the roller table 51 rises to the position of the ingot conveyor 44. 44
It is formed to be pushed out in the direction.

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

The ingots 2 and 3 that have been moved to the ingot holding position 55 are sequentially stacked on the stacking position 5 of the ingot delivery conveyor 45 by the stacking device 1. The ingots 2 and 3 stacked in a predetermined amount in this way are moved by the conveying force of the ingot carry-out conveyor 45 to the carry-out position 7 of the ingot carry-out conveyor 45, and are carried out to the outside by a forklift 56 at that position. It is something.

In this case, the ingots 2 and 3 are stacked by the stacking device 1 as follows.

That is, as an example, the number of foot-shaped ingots 2 is 4.
A case will be explained in which a total of 40 ingots, 36 ingots and 3 flat ingots, are stacked. In this case, the weight of each ingot 2 and 3 is 25 kg, and 1 lot is 1 ton.
That's a good break. At this time, the ingots 2 and 3 that have been moved on the ingot conveyor 44 to the ingot holding position 55 are arranged so that their longitudinal direction is the same as the moving direction, and the stacking claws 10
The direction of movement of the ingots 2 and 3 should be the same as that of the nail 10.
It is designed so that it can be held and transported.

The ingots 2 and 3 that have been sequentially moved to the ingot holding position 55 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 fabrication of the ingot case 48 and the draft angle. Due to this relationship, when the ingot is reversed and taken out from the continuous ingot casting machine 43 to the ingot transport conveyor 44, the teeth 4 face 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.

That is, as shown at the left end of FIG.
The stacking claws 10 are used to hold and transport the material until it reaches the maximum height. At that time, 10 is left as it is without rotating. Then, the foot-shaped ingot 2
is placed with one long side of the stacking claws 10 positioned on the line of movement of the stacking claws 10.

Next, as shown in the second part of FIG. It is rotated 180° to the left. 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 shown in Figure 5A.
As shown in the third part of FIG.
Since it is a sheet, there are three stopping positions 6, and it is moved to the stopping position 6 at the opposite end to the initial position. Then, at that position, the foot-shaped ingot 2 is placed without rotating the stacking claw 10. 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, 1/2 of the long side, the ingots face and come into contact with the short side of the maximum surface of the foot-shaped ingot 2 placed first. Moreover, they are arranged so that the long sides are located on the movement line of the stacking claws 10.

The fourth foot-shaped ingot 2 is in contact with the third foot-shaped ingot 2 on its long sides, as shown in the fourth part of FIG. And the second foot-shaped ingot 2
are arranged with their short sides facing each other and touching each other.

Foot-shaped ingots 2 arranged in this way
As shown in FIG. 6A, the teeth 4 are arranged downward, and the rectangles on the largest surfaces form two rows with their long sides facing each other.

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

This latter stage is arranged as follows.

That is, first of all, as shown in the left end of FIG. It is held and moved by the stacking claws 10, and placed by rotating the stacking claws 10 horizontally by 90 degrees so as to be on the outside with respect to the arrangement of the stop positions 6. 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 shown in Figure 5B.
As shown in the second part of the figure, the stop position 6 of the one end
Stop the stacking claw 10 at the stop position 6 next to
At that time, the stacking claws 10 are left as they are without being rotated. Then,
This flat ingot 3 is arranged so that its short side faces and contacts the long side of the first flat ingot 3, and its long side is located on the line of movement of the stacking claw 10.

Then, the third flat ingot 3 is placed at the same position as the second flat ingot 3 by moving the stacking claw 10 to the left or right side with respect to the direction of movement of the third flat ingot 3, as shown in the third part of FIG. 5B. It is rotated 180° and placed 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 line of movement 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 stops the stacking claw 10 at the stop position 6, which is located at the opposite end of the first flat ingot 3, as shown at No. 4 in FIG. 5B. Then, the stacking claw 10 is rotated 90 degrees so that the flat ingot 3 is located on the opposite side to the arrangement of the stop positions 6. That is, the flat ingots 3 are arranged symmetrically on the completely opposite side to the first flat ingot 3. Then,
The fourth flat ingot 3 is placed 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. becomes.

As a result, as shown in FIGS. 6A to 6E, the flat ingots 3 arranged in this manner are replaced by the foot-shaped ingots 2 or the flat ingots 3 arranged in a similar arrangement to this arrangement. When stacked on top of each other, they are stacked in the shape of a parallel grid. and,
By stacking the flat ingots 3 alternately in this way, there will be no continuous break from the bottom to the top, making it possible to stack them in a very strong and resistant state.

Also, in this case, if the number of stacked stages is even,
Since 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 attach the band 8 described later, the flat-shaped ingot 3 of the next tier of the foot-shaped ingots 2 is They should be placed in the same row as the row, and stacked on top of it one after another. If the number of stacked tiers is an odd number, it is sufficient to stack them alternately from the lowest tier to the highest tier. In other words, the arrangement at the bottom and the arrangement at the top may be the same.

As mentioned above, the operation of the stacking claw 10 is as follows.
All of this is controlled by the control device 36. The structure of this control device 36 is not particularly limited, but common ones include one having a sequence circuit or one consisting of an arithmetic device such as a computer. can be easily controlled. or,
At this time, the clamping of each ingot 2 and 3, transportation positioning, etc. are all performed by signals from a sensor (not shown), and the types of sensors generally include magnetic sensors, optical sensors, contact sensors, etc. used.

The ingots 2 and 3 thus stacked at the stacking position 5 are moved to the carry-out position 7 by the ingot carry-out conveyor 45. At that position, as shown in FIG. 7, the band 8 is hung and gathered together to prevent it from collapsing, and the lifting claw 57 of the forklift 56 is inserted into the gap created by the teeth 4 of the foot-shaped ingot 2. It is to be lifted up and carried 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 the numbers of ingots, first move the stacking claw 10 in a straight line and select one from the number of foot-shaped ingots 2 at intervals equal to the width of the maximum surface of each ingot 2, 3. It is possible to stop at a position equal to the number of ingots 2 and 3.
When the foot-shaped ingots 2 are held, the foot-shaped ingots 2 are formed so as to be horizontally rotatable about the center of one long side of the largest surface, and using the stacking claws 10, the foot-shaped ingots 2, which have been sequentially formed, are With the teeth 4 facing downward, the stacking claws 10 are placed at every other position from one end position at the stop position of the stacking claws 10 as they are without being rotated, and 180 degrees to the left or right with respect to the moving direction. The flat molds are successively arranged so that the longitudinal direction of the maximum surface is parallel to the moving direction of the stacking claws 10, and then the flat molds are sequentially formed. Ingot 3
, a stage in which the stacking claws are rotated and arranged in the same position as in the case of the foot-shaped ingot 2;
Stopping the stacking claws 10 at both ends of the stop position 6 of the stacking claws 10, at positions next to these, and at every other position from this neighboring position,
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 of the arrangement of the stop positions 6, and at the other stop positions 6, the stacking claws 10 are not rotated. It is operated by combining the state of
Similar to the foot-shaped ingot 2, the rows are arranged consecutively in two rows in which the longitudinal direction of the largest surface is parallel to the moving direction of the stacking claws 10, and the top row is a foot-shaped ingot. They can be stacked automatically if they are stacked in rows in the same way as ingot 2.

[Effects 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 having a substantially rectangular parallelepiped shape that has the same shape as the largest surface of the ingot and an appropriate number of times the number of the foot-shaped ingots 2 is turned downward to form a foot-shaped ingot. Stacking claws 10 formed so that they can be stacked by sequentially pinching from 2
Then, when the stacking claws 10 are holding each of the ingots 2 and 3, they are moved in a straight line and placed at a position equal to the number of foot-shaped ingots 2 minus 1 at intervals equal to the width of the maximum surface. The ingots 2 and 3 can be stopped, and the ingots 2 and 3 are held between the stacking claws 10 as they are, and the ingots 2 and 3 are rotated horizontally by 90 degrees around the center of one of the longest sides of the ingots 2 and 3, and by 180 degrees. A pawl moving device 20 that operates to place the ingots 2 and 3 in the stacking position in either the rotated state, and a pawl moving device 20 that operates to place the ingots 2 and 3 in the stacking position in either the rotated state, and the clamping by the stacking claws 10, release thereof, stop movement of the stacking claws 10, and adjust the rotation. A control device 3 that controls the stacking claws 10 and the claw moving device 20 so as to move the stacking claws at the same position.
6, the structure is simplified and the stacking work can be performed accurately.

Then, an even number of geta-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 successively molded so that the maximum surface has the same shape as the maximum surface of the foot-shaped ingots 2. If the approximately rectangular parallelepiped flat ingots 3 are successively molded by an appropriate number of times the number of foot-shaped ingots 2, all the foot-shaped ingots 2 are arranged in the bottom row,
An appropriate number of stages of flat ingots 3 can be stacked on top of it. Furthermore, even if the ingots 2 and 3 are stacked alternately vertically and horizontally, the length of the maximum surface is 2 and the width is 1, so the overall outer diameter of the rows is a rectangle with the same shape. Can be done. This allows them to remain stable when stacked.

Moreover, first, the sequentially molded foot-shaped ingots 2 are rotated with the stacking claws 10 at every other position from one end position at the stop position of the stacking claws 10, with the teeth 4 facing downward. It operates by combining the state where it is not moved and the state where it is rotated 180 degrees to the left or right with respect to the direction of movement,
Next, the sequentially formed flat ingots 3 are piled up in the same position as the foot-shaped ingot 2, and the steps are arranged by rotating the claws, and both ends of the stacking claws 10 at the stop position 6 are stacked. The stacking claws 10 are stopped at the position next to , and every other position from the next position, and at the stop positions 6 at both ends, the flat ingots 3 are stacked so that they are arranged on the outside of the arrangement of the stop positions 6. In addition to rotating the pawl 10 by 90 degrees, at other stop positions 6, the stacking pawl 10 is operated by combining a state in which it is not rotated and a state in which it is rotated by 180 degrees to the left or right with respect to the direction of movement. Similarly to foot-shaped ingot 2, the longitudinal direction of the largest surface is the stacked claw 1.
If the steps are arranged in two rows parallel to the direction of movement of the ingot 0, the steps are alternately overlapped, and the top step is arranged in the same way as the foot-shaped ingot 2. The work of automatically piling up the ingots 2 and 3 in a substantially parallel grid shape can be performed by moving the stacking claws 10 only in a straight line, and the structure of the stacking claws 10 can be greatly simplified.

Furthermore, when moving in a straight line, the operation of the stacking claws 10 at each stop position 6 is very simple, as the stacking claws 10 are simply rotated horizontally.
The structure of the device can be further simplified, and each ingot 2,
3 can be stacked in a stable state with almost no deviation as described above. As a result, when attempting to automate the work of stacking the main ingots, it can be easily carried out, and at the same time, the stacking work can be carried out accurately, so that the band 8 can be easily assembled without collapsing during packaging. can be multiplied by

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 carried out automatically without bothering the operator.

Further, since it has the above-mentioned 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 made easy to transport, difficult to shift, and easy to pack. In addition to achieving various excellent effects, such as minimizing equipment investment and maximizing the stacking effect.
