A pair of chain conveyors 25 driven by 0 are arranged.

Then, based on the respective input signals of the measuring mechanism 10 and the position detecting mechanism 12, the press machine 11, the feeding mechanism 14, the returning mechanism 15, the feeding mechanism 16, the elevator 17, the pushing mechanism 18, the pallet lifting mechanism 19, A control means 26 for appropriately operating the table moving mechanism 20, the lateral feed mechanism 21, both clamping mechanisms 23, the block transfer mechanism 24 and the chain conveyor 25 is provided. This control means 26
Is set in advance to a prescribed length of the total length of the aligned assembly 4 (a length that can be stacked on a pallet and is a length when both clamping members 232 of the clamping mechanism 23 approach each other). It has been entered.

When various scrap materials made of aluminum are compressed into blocks and stacked on a pallet by using the scrap press apparatus constructed as described above, first, before the operation, the positioning mechanism 22 is operated. Nut body 220
The positioning tool 22 supported by the pair of guide shafts 222 is rotated by adjusting the screw shaft 221 to move back and forth.
Place 3 in place.

Next, the operation of the scrap press machine is started, and the scrap material is charged through the charging hole 1. At this time, the weighing table 10 of the weighing mechanism 10 is placed in the charging hole 1.
2 is projected horizontally, and the weight of the scrap material dropped from the charging hole 1 is measured by the weighing platform 102. Then, when the measured value reaches a predetermined weight, the weighing table 102 is horizontally retracted from the inside of the charging hole 1 to drop the scrap material placed on the weighing table 102, and inside the press machine 11. Send to.

Then, by moving the piston rod of the lateral pushing cylinder 110 of the pressing machine 11 forward, the scrap material is scraped by the lateral pressing tool 111.
1 is pushed out to the side wall 112 side facing. As a result, the scrap material includes the lateral pressing tool 111, the side wall 112, and the upper wall 113 and the lower wall 1 that are continuous with the side wall 112, respectively.
It is pushed into the compression passage 115 composed of 14 and.

Further, by moving the piston rod of the main pushing cylinder 116 forward, the opening / closing cylinder 11 is previously moved.
9 is operated to slide the main pressing tool 117 along the inside of the compression passage 115 whose front end is closed by the opening / closing tool 118 to compress the scrap material in the compression passage 115 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 forward position of the main pressing member 117 by the position detecting mechanism 12. Since the block 2 thus compressed is formed by using the scrap material measured for each predetermined weight by the weighing mechanism 10, the width and the width of the block 2 regulated by the size of the compression passage 115 and The length of the block 2 as well as the height is maintained at a stable value without much dimensional variation as compared with the case where the conventional measuring mechanism 10 is not used.

Then, the opening / closing cylinder 119 is used to operate the opening / closing tool 118 to open the tip of the compression passage 115, and the main pushing cylinder 116 is used to move the block 2 in the compression passage 115 onto the mounting table 13. Extrude into. Then, 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 delivers 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 less than or equal to the predetermined value, the control means 26 stops the block 2 at the delivery 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 retracted 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 up and down the elevator 17 by the delivery tool 162 supported by the pair of guide shafts 161. Push it onto the table 171. Next, the piston rod of the upper and lower cylinders 174 is moved forward to lift the sprocket 173, thereby raising the block 2 placed on the upper and lower bases 171 via the chain 172.

Subsequently, the block 2 having arrived at the upper part of the elevator 17 is moved on the upper and lower bases 171 by advancing a piston rod of an extruding cylinder 180 of an extruding mechanism 18 and an extruding tool 182 supported by a pair of guide shafts 181. Push out from. In this case, the gear motor 207 of the table moving mechanism 20 is driven in advance to transmit the transmission mechanism 206 and the connecting shaft 2.
05, chain 204 through each sprocket 203
Is operated to move the slide table 200 supported by the rotating roller 202 along both rails 201 to just above the lift table 191 of the pallet lift 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 which has been retracted in advance by the rotating cylinder 244 of the block transfer mechanism 24 above the transport path of the block 2 by the pushing tool 182.
Is moved downward and positioned on 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 to support the transfer body supported by the pair of slide shafts 240. By moving 242 together with the aligning plate 243, the aligning plate 243 pushes out the first block 2 for a predetermined distance.

At this time, since the first block 2 has a predetermined length or less selected as described above,
Due to the transfer of the first block 2, the front end of the first block 2 does not exceed the front end limit set in advance on the slide table 200, and there is an obstacle in the lateral feeding of the aligned assembly 4 described later. Never becomes.

Next, the above-described series of operations is repeated in order to carry the next block 2 (referred to as a second block 2) onto the slide table 200. This allows
The second block 2 is placed on the slide table 200, and the aligning plate 243 retracted above the transport path of the second block 2 is rotated downward to move the rear side of the second block 2. After being positioned on the end side, the alignment plate 243 is moved from the rear end surface of the first block 2 placed above to a position spaced apart from the rear end surface by a predetermined distance, whereby the second block
Blocks 2 of 2 are aligned after the first block 2.

In this case, the second block 2 also has a predetermined length or less, and the second plate formed by the aligning plate 243 has a second length.
Since the transfer position of the block 2 is set to be apart from the transfer position of the first block 2 by a certain distance from the predetermined length of the block 2, the transfer position is between the first block 2 and the second block 2. , The second block 2 does not push the first block 2 to the front side. Then, the third block 2 is also smoothly aligned with the rear end side of the second block 2 by the above-described operation.

Further, by the same operation, the fourth block 2 is aligned with the rear end of the third block 2. In this case, the respective lengths (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 a pallet and is a length when both clamping members 232 of the clamping mechanism 23 approach each other). The length of the fourth block 2 (L
4) determines whether “L− (L1 + L2 + L3)> L4” is satisfied.

That is, the retracted position 13 of the mounting table 13 described above.
Block 2 that was temporarily saved to 1 has the above length (L4)
If the condition of is satisfied, the piston rod of the return cylinder 150 of the return mechanism 15 is moved forward to move the pair of guide shafts 1
The return tool 152 supported by 51 returns the block 2 at the retracted position 131 to the delivery position 130, and the block 2 is delivered as the fourth block 2. As a result, even the blocks 2 that exceed the predetermined length can be effectively used and stacked without being discarded. On the other hand, when the above conditions are not satisfied, the press machine 11
The next block 2 is supplied from the side.

In this way, the four blocks 2 are arranged in a line to form the aligned assembly 4. At this time, in the aligned assembly 4, the first to third blocks 2 each have a predetermined length or less, and the fourth block 2 satisfies the above conditions. The front end position of the second 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 exceeded, and the lateral feed operation of the aligned aggregate 4 by the lateral feed mechanism 21 described below is smoothly performed.

The aligned assembly 4 thus arranged on the slide table 200 is moved laterally by the pair of guide shafts 211 by advancing the piston rod of the lateral feed cylinder 210 of the lateral feed mechanism 21. Feeder 2
12, the positioning tool 22 of the positioning mechanism 22
It is sent to the 3rd side. Then, the next aligned assembly 4 is aligned on the slide table 200 by the same procedure as described above, and is fed to the positioning tool 223 side by the transverse feed mechanism 21.

By repeating this operation, four sets of aligned assemblies 4 are laterally fed to arrange a total of 4 × 4 = 16 blocks 2 on the slide table 200 in a plane. Subsequently, the piston rods of the pair of pinching cylinders 230 of the pinching mechanism 23 are advanced to move the pair of guide shafts 2 one by one.
Both clamping members 232 supported by 31 are brought close to each other to press both ends of each aligned assembly 4 to align the entire length of each aligned assembly 4.

In this case, the selection length of the block 2 and the selection length of the block 2 are set with a margin so that a required gap is formed between the four blocks 2 forming each of the aligned assemblies 4. Since the specified length L of the aligned assembly 4 has been set, when the both clamping members 232 are brought close to each other to a predetermined distance and both ends of each aligned assembly 4 are pressed by both clamping members 232, The interval between the blocks 2 can be smoothly shortened, and the blocks 2 do not come into close contact with each other to prevent further shrinkage. Therefore, the total length of the aligned assemblies 4 does not vary.

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

In this case, in the block 2 group stacked on the pallet, the width and height of each block 2 are accurately regulated by the size of the compression passage 115 of the press 11 as described above. When the slide table 200 is pulled out in the horizontal direction in a state in which the four sets of the aligned assembly 4 are pressed against the positioning tool 223 by the lateral feed tool 212, the width directions of the blocks 2 are assembled to each other. The tight contact ensures that the blocks 2 do not fall apart and fall, and are securely supported between the lateral feed tool 212 and the positioning tool 213. Tool 212
And the positioning tool 213 are separated from each other, the block 2 group sandwiched therebetween is integrally lowered and landed smoothly on the pallet.

Then, the piston rod of the lifting cylinder 194 is retracted to lower the lifting table 191 by a certain height, and then the slide table 200 is placed on the first block 2 group of the lifting table 191. Move it again,
By repeating the above operation on the 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 transferred smoothly. .

In this way, the blocks 2 of a plurality of stages are placed on the pallet of the lift 191 and the lift 19 is lifted.
When the blocks 2 are fully stacked on the elevator 1, the elevator 191
By moving down, the stacked blocks 2 are delivered together with the pallet onto the pair of chain conveyors 25, and the chain mechanisms 25 are driven by the drive mechanism 250 to carry out the stacked blocks 2.

In this case, in the block 2 group laminated on the pallet, the width and height of each block 2 are accurately regulated by the size of the compression passage 115 of the press machine 11, so that By the feed mechanism 21 and the positioning mechanism 22, the width directions of the blocks 2 are gathered together and firmly adhered to each other, while the clamping mechanisms 23, 2 are both pressed.
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).
The length up to the rear end) is surely aligned. As a result,
Since the distance between the two sets of opposing outer surfaces of the two block groups stacked on the pallet is kept constant and the height is kept constant, the two block groups stacked one above the other horizontally. There is no variation in the dimension in the vertical and vertical directions, and therefore, there is no collapse of the load on the pallet, and it is possible to reliably stack and transport the pallets.
