With reference to FIG. 7, a specific method for transporting the profile from the cooling table to the saw table will be described.

In the second cooling table 5, the section is cooled by a cooling fan 18 while the section is conveyed by a belt conveyor 19 driven by a motor via a pulley 17.

Subsequently, stretching is performed on the first transfer table 8. In order to advance the table stock 7 toward the end of the profile to be gripped, as shown in FIG. 8, tail stock running wheels 20 and a cable carrier 24 are provided so as to be able to run on rails 21 and upper and lower claws. The first transfer table retracts when the tail stock 7 for moving the gripping portion constituted moves.

This is a place to temporarily stock the number of profiles that almost match the capacity of the extruder and the cutting machine of the storage table 9, and has its own motor 25 so that it can absorb fluctuations in the amount of extrusion and cutting, and the pulley 26 The speed at which the profile 30 is conveyed is adjusted. Reference numeral 27 denotes a belt, and reference numeral 28 denotes a free roller. By operating these belts, the number of shaped members 30 that can be cut at one time is transferred to the saw table 11 at the same time. Saw table
Reference numeral 11 denotes a configuration in which a number of saw table rollers 31 driven by a conveyor chain 32 are arranged in the longitudinal direction of the shape member 30, and overlaps the second transfer table. The second transfer table 10 rotates counterclockwise (in the drawing) to receive the profile 30 and then rotates clockwise to move the profile 30 to the saw table 11.
And wait in that state. The section 30 is moved at a high speed toward the cutting machine after the previous section has been cut.

In the past, the cutting machine was provided on the extruder side. However, as shown in FIG. 7, the cutting machine 12 is provided in front of the extruder 1 in recent post-processing equipment as the productivity and throughput increase. Is now available.

Although the typical rear equipment has been described above, in addition to the above, a rear equipment in which a sub-stretcher disclosed in JP-A-63-212012 is provided at the boundary between the run-out table and the cooling table has also been put to practical use. A sub-stretcher is also proposed in Japanese Patent Publication No. 1-306015.

Recently, the length of the aluminum billet has been increased to increase the yield and productivity, and the weight of a single aluminum billet has been increased.
It is getting longer to ~ 65m. The length of the cooling table and saw table has been increased in response to the extension of the profile.
It has become 60-65m long.

(Problems to be solved by the invention) Although the rear equipment has been lengthened in this way, instead of always extruding the maximum length of the profile, in the case of small lot production, it is also possible to extrude only 15 m with one billet. is there. In this case, a 15-m section must be moved by the saw table 11 toward the cutting machine 12 by 45 to 50 m (60 to 65-15 m), and its moving feed speed 8 is not surface-treated. Assuming 80 m / min, which is considered to be the boundary of the feed speed of the shape
Requires 8 seconds. During this time, the extruder continues to extrude, and since the cutting machine is not operating, the profile material accumulates on the cooling table. The extruder must be stopped in the worst case when a section exceeding the cutting machine capacity is waiting for cutting on the cooling table.
As countermeasures against this, it is conceivable to improve the cutting ability, such as by increasing the saw blade rotation and the saw blade feed speed, but all have limitations.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the post-processing equipment of a profile so as to reduce the downtime of a cutting machine.

(Means for Solving the Problems) According to the present invention, a transfer table having a length substantially equal to or longer than the cooling table is provided on the rear side of the stretcher and on the front side of the saw table so that the aluminum extruded shape can be transferred in the extrusion direction. The upper surface of the table engaged with the extruded aluminum member is configured to be movable up and down.

In the present invention, a transport table having the same feeding function as a saw table (hereinafter, referred to as a transit table)
Is provided in front of the saw table, and when a 15-meter profile is extruded in the above-described example, the profile is advanced, and then the profile is transferred to the saw table. The upper surface of the transit table for feeding the profile can be moved up and down so that the upper surface of the table is engaged with the profile only when performing the same feed as the saw table.
That is, the raised table upper surface engages with the profile, and conveys the profile in the extrusion direction. When such transport is not performed, the profile moves laterally or stops on the transit table.

The sections enter the transit table after being stretched. This is related to the fact that the stretcher headstock 6 (FIG. 7) is provided on the extruder side in modern post-processing equipment, and the extrusion is performed so that the head side of the profile is set at the position of the stretcher headstock 6. This is because the tail stock 7 moves to the table side. In other words, when the profile is advanced by the transit table and then stretched, the stretcher headstock 6 cannot grip the profile.

The length of the transit table should be approximately the same as the length of the cooling table so as not to obstruct the passage of the longest profile that is approximately the same as the length of the cooling table. Make it possible to postpone to reach the table tip. Also,
When the cutting machine is located considerably ahead of the cooling table tip, the transit table and the second transfer table may be longer than the cooling table.

The installation position of the transit table can be inside or at the end of the storage table, or inside or at the end of the second transfer table.

The most efficient post-processing method using the above-mentioned post-processing equipment is that when the cross-section arrives at the transit table, if the cross-section is almost the same length as the transit table, it is transferred to the saw table through the transit table. If the profile is substantially shorter than the length of the transit table, it is conveyed on the transit table in the extrusion direction to the end of the transit table, and then transferred in the direction of the saw table.

The reason that the length of the section becomes shorter than the cooling table may be the case where a thick section is extruded, in addition to the case of small-scale production. In the latter case, the length of the profile is less than the maximum length, the shorter one is 15
m becomes shorter. If a profile 1m shorter than the cooling table is forwarded on the transit table, the transport speed will be 80m /
In the case of seconds, it is sent to the end of the transit table in about one second. This shortens the transport on the saw table by about 1 second, and reduces the cutting waiting time of the cutting machine by about 1 second. For a section shorter than 10m, the cutting wait time can be further reduced by transporting it on a transit table. That is, even if the profile is short, even if it is 1 m long, the above-mentioned one second time can be reduced to zero and the cutting waiting time can be reduced to almost zero by advancing the profile using the transit table.

(Operation) The transit table is provided in front of the saw table, and the advance of the stretched profile in the cutting machine direction (extrusion direction) and the distribution of the profile in the lateral direction are performed on the same transit table. . This enhances the cutting efficiency of profiles of varying lengths.

(Embodiment) FIG. 1 shows a rear equipment in which a transit table 50 according to the present invention is installed on the rear equipment of FIG. The transit table 50 is provided in the middle of the storage table 9.

FIG. 5 is the storage table and saw table of FIG.
11, the transit table 50 is lower than the upper surface of the storage table 11, and the profile 30 is moving in the direction of the saw table 11. In FIG. 6, the transit table 50 is raised above the upper surface of the storage table 9 to advance the profile 30 forward in the plane of the drawing.

The detailed structure of the transit table is shown in FIG. 2, FIG. 3, and FIG.

In the figure, 9a is the upper surface of the storage table 9, and 9b is a number of beams constituting the storage table 9.

The surface where the transit table engages with the profile is constituted by a set of three free rollers 41 and a belt conveyor 54.
A frame 55 holding both ends of the free roller 41 and the belt conveyor 54 is fixed to the stage 43, and the upper and lower guide rollers 44 provided at one end of the stage 43 move up and down guide columns 56,

57 moves. After the stage 43 has been lifted, the cutting machine 1
When the number of cut sections per transfer is transferred to the upper surface of the saw table, the motor 42 is started to transport the section to the tip of the saw table.

(Effects of the Invention) In the current extrusion technology, the productivity of the extruder and the cutting machine has been greatly enhanced, but the post-processing equipment cannot keep up with these productivity. As a result, the use of a sub-stretcher significantly improved productivity of the internal cooling of the post-processing equipment, and the ratio of waiting for cutting due to the delay due to the post-processing was greatly increased. It was long-awaited. The present invention can reduce or eliminate the waiting time for post-processing, and greatly contributes to improving the productivity of profile materials.
