This control means 26
In advance, a specified length of the entire length of the aligned assembly 4 (a length that can be loaded on the pallet and a length when the two pressing tools 232 of the pressing mechanism 23 approach each other) is set in advance. Has been entered.

In the case where various scrap materials made of aluminum are compressed into blocks and laminated on a pallet using the scrap press device configured as described above, first, prior to the operation, the positioning mechanism 22 is controlled. Nut body 220
By rotating the screw shaft 221 to adjust the position of the positioning tool 22 supported by the pair of guide shafts 222.
3 is set at a predetermined position.

Next, the operation of the scrap press apparatus is started, and the scrap material is charged from the charging hole 1. At this time, the weighing table 10 of the weighing mechanism 10 is
2 is horizontally projected, and the weight of the scrap material dropped from the charging hole 1 is measured by the weighing table 102. Then, when the measured value reaches a predetermined weight, the weighing table 102 is retracted in the horizontal direction from the charging hole 1 so that the scrap material placed on the weighing table 102 is dropped, Send to

Subsequently, by moving the piston rod of the lateral pushing cylinder 110 of the press machine 11 forward, the scrap material is removed by the lateral pushing tool 111.
1 is extruded toward the side wall 112 side. As a result, the scrap material is transferred to the lateral pressing tool 111, the side wall 112, and the upper wall 113 and the lower wall 1 connected to the side wall 112, respectively.
14 are pushed into the compression passage 115 formed by the compression passage.

Further, by moving the piston rod of the main push cylinder 116 forward, the open / close cylinder 11
9, the main pressing tool 117 is slid along the compression passage 115 in a state where the distal end is closed by the opening / closing member 118, and the scrap material in the compression passage 115 is compressed to block 2 And

At this time, the length of the block 2 is input to and stored in the control means 26 by detecting the advance position of the main pressing tool 117 by the position detecting mechanism 12. Since the block 2 compressed in this manner is formed by using the scrap material measured for each predetermined weight by the measuring mechanism 10, the width and the width of the block 2 regulated by the dimensions of the compression passage 115 are set. Not to mention the height, the length of the block 2 is maintained at a stable value with no remarkable dimensional variation compared to the case where the conventional weighing mechanism 10 is not used.

Next, the opening / closing tool 118 is operated by the opening / closing cylinder 119 to open the distal end of the compression passage 115, and the block 2 in the compression passage 115 is placed on the mounting table 13 by the main pushing cylinder 116. Extrude. Subsequently, the piston rod of the delivery cylinder 140 of the delivery mechanism 14 is advanced, and the delivery tool 142 supported by the pair of guide shafts 141 sends the block 2 on the mounting table 13 to the delivery position 130 or the retreat position 131. . That is, when the length of the block 2 is equal to or less than the predetermined value, the control means 26 stops the block 2 at the transmission position 130 and the length of the block 2 exceeds the predetermined value. In this case, the control means 26
Stops the block 2 at the retreat position 131.

Then, the block 2 stopped at the delivery position 130 advances the piston rod of the delivery cylinder 160 of the delivery mechanism 16 and moves the elevator 17 up and down by the delivery tool 162 supported by the pair of guide shafts 161. Push on the table 171. Next, the piston 2 of the upper and lower cylinders 174 is advanced, and the sprocket 173 is lifted, thereby raising the block 2 placed on the upper and lower bases 171 via the chain 172.

Subsequently, the block 2 arriving at the upper part of the elevator 17 is moved forward by the piston rod of the pushing cylinder 180 of the pushing mechanism 18 and pushed by the pushing tool 182 supported by the pair of guide shafts 181 on the upper and lower bases 171. Extrude from In this case, the gear motor 207 of the table moving mechanism 20 is driven in advance, and the transmission mechanism 206 and the connecting shaft 2
05, via each sprocket 203, the chain 204
Is operated, the slide table 200 supported by the rotating roller 202 is moved along the two rails 201 to just above the elevating table 191 of the pallet elevating mechanism 19. As a result, the block 2 (referred to as the first block 2) extruded by the pushing tool 182 is placed on the slide table 200.

Further, the aligning plate 243 previously retracted above the conveying path of the block 2 by the pushing tool 182 by the rotating cylinder 244 of the block transfer mechanism 24.
Is pivoted downward and positioned at the rear end side of the first block 2, and then the piston rod of the transfer cylinder 241 is advanced by a predetermined distance, and the transfer body supported by the pair of sliding shafts 240 is moved. By moving 242 together with the alignment plate 243, the first block 2 is pushed out by the alignment plate 243 by a predetermined distance.

At this time, since the first block 2 is shorter than a predetermined length selected as described above,
By the transfer of the first block 2, the front end of the first block 2 does not exceed the front end limit previously set on the slide table 200, which hinders the later-described lateral movement of the aligned assembly 4. And never.

Next, a series of operations described above are repeated to carry the next block 2 (referred to as the second block 2) onto the slide table 200. This allows
The second block 2 is placed on the slide table 200, and the alignment plate 243 that has been retracted above the transport path of the second block 2 is rotated downward, and After being positioned on the end side, the alignment plate 243 is transferred from the rear end surface of the first block 2 placed earlier to a position spaced at a predetermined distance from the first block 2, thereby obtaining the second block.
Is aligned after the first block 2.

In this case, the second block 2 is also shorter than a predetermined length, and the second block 2
Since the transfer position of the block 2 is set to be somewhat away from the transfer position of the first block 2 to a certain extent from the predetermined length of the block 2, the distance between the first block 2 and the second block 2 is However, the second block 2 does not push out the first block 2 to the front side because a certain gap is opened. Subsequently, the third block 2 is also smoothly aligned with the rear end side of the second block 2 by the above-described operation.

Further, the fourth block 2 is aligned with the rear end of the third block 2 by the same operation. In this case, each length (L1,
L2, L3) are summed by the control means 26 (L1
+ L2 + L3), a predetermined length of the total length of the aligned assembly 4 that has been input in advance (a length that can be loaded on the pallet, and a length when the two pressing tools 232 of the pressing mechanism 23 approach each other). L, the length of the fourth block 2 (L
It is determined whether or not 4) satisfies “L− (L1 + L2 + L3)> L4”.

That is, the retracted position 13 of the mounting table 13
Block 2 temporarily saved to 1 is the above length (L4)
Is satisfied, the piston rod of the return cylinder 150 of the return mechanism 15 is advanced, and the pair of guide shafts 1
The block 2 at the retreat position 131 is returned to the delivery position 130 by the return tool 152 supported by 51, and this block 2 is delivered as the fourth block 2. As a result, even if the blocks 2 exceed a predetermined length, they can be effectively used and stacked without being discarded. On the other hand, if the above conditions are not satisfied, the pressing machine 11
The next block 2 is supplied from the side.

In this manner, the four blocks 2 are arranged in a line, and the aligned aggregate 4 is formed. At this time, in the aligned aggregate 4, the first to third blocks 2 each have a predetermined length or less, and the fourth block 2 satisfies the above condition. The front end position of the block 2 does not exceed the front end limit set on the slide table 200, and the rear end position of the fourth block 2 is defined by the alignment plate 243. The front end limit and the rear end limit on the table 200 are not respectively exceeded, and the traversing operation of the aligned assembly 4 by the traversing mechanism 21 described below is performed smoothly.

The alignment assembly 4 aligned on the slide table 200 in this manner moves the piston rod of the traversing cylinder 210 of the traversing mechanism 21 to advance, so that the horizontal assembly supported by the pair of guide shafts 211 is moved. Feeder 2
12, the positioning tool 22 of the positioning mechanism 22
It is sent to 3 side. Next, the next aligned assembly 4 is aligned on the slide table 200 by the same procedure as described above, and is sent to the positioning tool 223 by the lateral feed mechanism 21.

By repeating this operation, the four aligned assemblies 4 are laterally fed, and a total of 4 × 4 = 16 blocks 2 are arranged in a plane on the slide table 200. Subsequently, by moving the piston rods of the pair of clamping cylinders 230 of the clamping mechanism 23 forward, the pair of guide shafts 2
The two pressing tools 232 supported by 31 are brought close to each other to press both ends of each alignment assembly 4, and the entire length of each alignment assembly 4 is aligned.

In this case, the separation length of the blocks 2 and the sorting length of the blocks 2 are set with a margin so that a required gap is formed between each of the four blocks 2 constituting each of the aligned aggregates 4. Since the specified length L of the alignment assembly 4 is set, the pressing members 232 are brought close to each other to a predetermined interval, and when both the pressing members 232 press both ends of each alignment assembly 4, The distance between the blocks 2 can be reduced smoothly, and the blocks 2 do not come into close contact with each other and do not shrink any more. Therefore, the total length of the aligned assemblies 4 does not vary.

By retracting the piston rods of the two pressure cylinders 230, a pair of guide shafts 2 are provided.
After separating the two pressure tools 232 supported by 31 from each other, in a state where the four sets of aligned assemblies 4 are pressed against the positioning tool 223 by the lateral feed tool 212, the gear motor 207 of the table moving mechanism 20 is used. By pulling out the slide table 200 in the horizontal direction and returning the lateral feeder 212 to the original position,
The set of aligned assemblies 4 is lowered and gently placed on the pallet of the lifting platform 191 of the pallet lifting mechanism 19.

In this case, the width and height of each block 2 of the group of blocks 2 stacked on the pallet are precisely regulated by the size of the compression passage 115 of the press machine 11 as described above. When the slide table 200 is pulled out in the horizontal direction in a state where the four sets of aligned assemblies 4 are pressed against the positioning tool 223 by the lateral feeder 212, the width directions of the blocks 2 are gathered together. Since the blocks 2 are firmly adhered to each other, the blocks 2 do not fall apart and fall, and are reliably supported between the traversing tool 212 and the positioning tool 213. Tool 212
By separating the positioning block 213 and the positioning tool 213, the blocks 2 interposed therebetween descend integrally and smoothly land on the pallet.

Next, the piston rod of the elevating cylinder 194 is retracted to lower the elevating table 191 by a certain height, and then the slide table 200 is placed on the first group of blocks 2 of the elevating table 191. Move it again,
By repeating the above operation on this slide table 200, four sets of aligned assemblies 4 are placed. In this case, by moving each block 2 along the slide table 200, the friction between each block 2 and the slide table 200 can be reduced, so that each block 2 can be smoothly transferred. .

In this manner, the plurality of blocks 2 are placed on the pallet of the elevator 191 and
When the blocks 2 are fully stacked on the platform 1, the elevator 191
Is lowered, the stacked blocks 2 are delivered together with the pallets onto the pair of chain conveyors 25, and both chain conveyors 25 are driven by the drive mechanism 250, and the stacked blocks 2 are unloaded.

In this case, the width and height of each block 2 of the group of blocks 2 stacked on the pallet are precisely controlled by the size of the compression passage 115 of the press machine 11. By the feed mechanism 21 and the positioning mechanism 22, the width directions of the respective blocks 2 are gathered together and firmly adhered to each other, while the two pressing mechanisms 23, 2
3, as described above, the total length of each of the aligned assemblies 4 (from the front end of each first block 2 to the fourth block 2
Length to the rear end) is surely aligned. As a result,
The distance between the two sets of opposing outer surfaces of the two groups of blocks stacked on the pallet is kept constant, and the height is kept constant. There is no variation in the dimensions in the direction and the vertical direction, so that the load does not collapse on the pallet, and the pallet can be reliably stacked and transported.
