Next, a case will be described in which the extruded material B is cut into a fixed size by using the extruded material fixed-size cutting device configured as described above.

First, the first arm 6c of the first transfer mechanism 6 is positioned lower than the height of the roller 4a of the run-out table 4, the upper roll 2b of the pinch roll 2 is retracted upward, and the pair of After confirming that there is no extruded material B on the run-out table 4 by the photoelectric tube, the indirect extruder 1 is operated, and the initial table 3 and the run-out table 4 are operated at a medium speed. As a result, the extruded material B extruded from the indirect extruder 1 is transferred on both tables 3 and 4. When the extrusion in the indirect extruder 1 is completed, each table
The speed of 3,4 is reduced, the upper roll 2b of the pinch roll 2 is lowered based on the completion of the shearing of the indirect extruder 1, and then the speed of each of the tables 3,4 is increased. Then, the extruded material B passes through the pinch roll 2, the upper roll 2b descends, and the lower roll 2d
Is detected, the speed of each of the tables 3 and 4 is increased, and the upper roll 2b of the pinch roll 2 is raised.

Subsequently, the extruded material B being transferred on both tables 3 and 4
Is detected by one of a pair of photoelectric tubes arranged near the end of the run-out table 4, the speed of each of the tables 3 and 4 is reduced, and when detected by the next photoelectric tube, each of the tables 3 and 4 is detected.
Stop 4 Thus, the extruded material B stops at a predetermined position on the run-out table 4.

Next, the mounting portion of the second arm 8c of the second transfer mechanism 8
8f in the cooling tank 5, the first arm 6c is rotated about the rotation shaft 6b by the kicker cylinder 6a of the first transfer mechanism 6, and the extruded material B is moved to the first arm 6c.
After being placed on the top and put into the cooling bath 5 according to the area of the first arm 6c, the first arm 6c is returned to the original position. Thus, the extruded material B is cooled while being placed on the placement portion 8f of the second arm 8c in the cooling tank 5. Then, after the extruded material B is cooled for a predetermined time, the second arm 8c is rotated about the rotation shaft 8b by the charger cylinder 8a of the second transfer mechanism 8, and is placed on the mounting portion 8f of the second arm 8c. Extruded material B
Lift the chain conveyor on the stock table 7
Place on 7b. As a result, as shown in FIG. 2, the extruded material B stops in accordance with the inclination of the chain conveyor 7b.
Rolls to position 7d and stops.

By repeating the above operation, two stoppers adjacent to the chain conveyor 7b of the stock table 7
When a predetermined number (for example, five) of the extruded materials B are placed between 7d, the chain conveyor 7b moves by one pitch (corresponding to the interval between two adjacent stoppers 7d). And
When the chain conveyor 7b moves by one pitch, a predetermined number of extruded materials B placed on the tip side (saw charge table 9 side) of the chain conveyor 7b are transferred onto the saw charge table 9. In this case, the roller 9a of the saw charge table 9
Since it is inclined downward from the side to the opposite side (see FIG. 2), the predetermined number of extruded materials B are placed on the rollers 9a of the saw charge table 9 in a state of being arranged in a horizontal row.
Next, the extruded plate 14a of the remaining material pusher 14 is retracted from above the roller 9a of the saw charge table 9, and both the vise 12, 13 are both open (both pressers 12a, 13a are retracted upward). When it is confirmed that the circular saw blade 10b of the circular saw cutting machine 10 is retracted on the same side as the extruded plate 14a, the saw charge table 9 and the saw gauge table 15 are operated at high speed. Then, when the tip of the push rod B interrupts the photoelectric tube installed on the upstream side of the circular saw cutting machine 10, the counting of the feed amount (length) starts, and when the feed amount reaches 90% of the set value, the two tables 9, 15 are started. Is set to low-speed operation, and when the set value is reached, both tables 9 and 15 are stopped.

Subsequently, the pressing element 1 is moved by the cylinder 13b of the entry-side vise 13.
After lowering 3a and fixing the extruded material B between the presser 13a and the roller 10d, the circular saw blade 10b of the circular saw cutting machine 10 is advanced by the cutting blade cylinder 10c, and the tip of the extruded material B The part (front ear) is cut, and then the circular saw blade 10b is retracted. In this case, the cut end of the extruded material B falls downward and is housed in the front ear container 19a via the chute 19b.

Further, after the front ear cutting step is completed, the process proceeds to the fixed length cutting step. That is, first, the stop plate 11a of the saw gauge stopper 11 is lowered on the roller 15a of the saw gauge table 15, and after the clamped state of the entry vise 13 is released,
The tables 9 and 15 are operated at high speed. Next, when the extruded material B blocks one of the pair of photoelectric tubes arranged upstream of the saw gauge stopper 11, each of the tables 9, 15 becomes slow.
Stops. In this case, the tip of the extruded material B is in contact with the stop plate 11a of the saw gauge stopper 11, and in this state, the extruded material B is clamped by the presser 13a of the entry-side vise 13, and the saw gauge stopper 11 is Stop plate 11a
Is rotated upward and retracted about the rotation shaft 11c by the cylinder 11d. Subsequently, the circular saw blade 10b of the circular saw cutting machine 10
By operating the cutting cylinder 10c, the extruded material B is moved forward to cut the extruded material B, then retracted, and further, the clamp of the entry-side vise 13 is released.

Next, the saw gauge table 15 is driven at a high speed for a predetermined time and then dropped to a low speed. Further, the tip of the cutting material C is pressed against the rotating plate 17b of the table end stopper 17 by contact pressing.
When the retracting of the 7d is detected by the limit switch, the saw gauge table 15 is stopped, and the cylinder 11d of the saw gauge stopper 11 causes the stop plate 11a to rotate downward about the rotation shaft 11c, thereby stopping the roller 15a. To lower. Next, the stop arm of the cutting material stopper 18
In a state where 18d is projected above the chute 16c, the dispensing body 16b is operated by operating the dispensing cylinder 16a of the cutting material dispensing device 16.
After the cutting material C on the roller 15a of the saw gauge table 15 is pushed out toward the chute 16c, the dispensing body 16b is retracted and returned to the original position. As a result, the cut material C discharged from the saw gauge table 15 is moved to the stop arm 18d at the intermediate portion of the chute 16c.
Stopped by And cutting material container 16d
Is not full, the stop arm 18d is rotated about the rotation shaft 18c by the cylinder 18a of the cutting material stopper 18 to retract from the chute 16c, and the cutting material C is stored in the cutting material container 16d. I do. Next, the stop arm 18d is again projected onto the chute 16c.

By repeating the above operation, a large number of cut materials C cut to a fixed size from the extruded material B can be obtained. Further, the extruded material B
When the extruded material B is not blocked by the photoelectric tube installed upstream of the circular saw cutting machine 10 (the remaining length is less than 1 m), the extruded material B is fixed by the presser 12a of the exit vise 12, and then the circular saw cutting machine 10 The extruded material B is cut by the circular saw blade 10b. Then
Chute the residual material by the extrusion plate 14a of the residual material pusher 14.
While being stored in the remaining material container 14d via 4c, the clamp of the exit vise 12 is released, and the cut material in the clamped state is stored in the cut material container 16d in the same procedure as described above. When a series of cutting processes are completed in this way, the next new push rod B is received on the saw charge table 15 and the process is repeated again from the front ear cutting step.
