Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to equipment for running strips, foils, etc.

[Prior Art] In a continuous strip processing line, the rear end of the preceding strip and the leading end of the following strip are welded by a welding machine installed in the line. It is necessary to stop the leading end of the strip, but it is necessary to continuously feed the preceding strip to the downstream side without stopping it and perform a predetermined process.

For this reason, conventionally, a looper device for temporarily storing the strip is installed downstream of the line of the welding machine, and in order to weld the trailing end of the preceding strip and the tip of the following strip with the welding machine, When stopping the trailing end and the leading end of the following strip, the preceding strip previously stored in the looper device is continuously discharged to the downstream side and the strip is processed.

FIG. 9 shows an example of continuous strip heat treatment equipment equipped with the above-mentioned looper device 1 and welding machine 2.
1 heating device 5, cooling device 6, priddle roll 7, skin pass mill 8, flying shear 9, winding machine 10a,
10b are sequentially arranged from the upstream side to the downstream side of the strip 11.

In addition, other continuous processing lines for strip-shaped materials such as the strip 11 are also shown together with a looper device in, for example, Japanese Utility Model Application Laid-open No. 63-1801013.

[Problems to be Solved by the Invention] However, in the continuous processing line for strips as described above, since it is assumed that the front and rear ends of the strips are joined, a joining device of the welding machine 2 is required, and Since the strips are stopped during welding, a looper device l is also required to ensure continuous operation in the heating device 5 and the cooling device 6. Moreover, the strips joined by the welding machine 2 are transferred to the heating device 5. After the heat treatment by the cooling device 6, the strip is wound up by the winder 10a (or 10b), and when a predetermined amount of the strip is wound up by the chain winder 10a (or job), the flying shear 9 cuts the strip again. However, there was also waste in terms of operation, as the belt-like material that was subsequently sent by the winder fob (or 10a) had to be wound up.

In view of the above circumstances, the present invention aims to provide a strip-shaped material traveling facility that can process a strip-shaped material without joining the front and rear ends of the strip and cutting it.

[Means for Solving the Problems] The present invention provides a guide rail laid in a strip processing device in the direction of conveying the strip, a traveling platform that can run along the guide rail, and a traveling platform. a traveling drive mechanism for moving the traveling base on a retreat track that runs along the guide rail from an upstream end to a downstream end, and returns from the downstream end of the guide rail to the outside of the processing device and returns to the upstream end of the guide rail. The present invention is characterized by comprising: a gripper disposed on the traveling base and capable of gripping and opening the front and rear ends of the strip-like object; and an opening/closing drive mechanism for opening and closing the gripper.

[Function] Therefore, when the opening/closing drive mechanism is activated to cause the gripper to grip the tip of the strip, and the traveling drive mechanism is activated to cause the traveling platform to travel from the upstream end to the downstream end along the guide rail, The strip is passed through a processing device. When the traveling platform reaches the downstream end of the guide rail, the gripper releases the strip by the opening/closing drive mechanism, and the traveling platform moves on the evacuation track by the operation of the traveling drive mechanism and returns to the upstream end of the guide rail. With the gripper gripping the rear end of the strip and the leading end of the following strip by the operation of the opening/closing drive mechanism, the traveling platform runs again along the guide rail,
Subsequent strips are threaded into the processing device.

Next, the operation of the above embodiment will be explained.

After the strip 11 rewound from the unwinding machine 3 in FIG. 1 passes through the leveler 4 and the surface shape is corrected, its tip is moved to the upper and lower fixed cam followers 33 shown in FIG.
．． Gripper 2 waiting in an open state on the upstream side of 34
0, the sprocket 14 is driven by the motor, and the carriage 16 moves along the guide rail 13 along the strip transport line X in synchronization with the unwinding speed of the strip 11.

A driving eccentric cam 29.30 fitted on a cam shaft 252B that projects laterally from the traveling base 16 is connected to the traveling base 16.
When the driving eccentric cam 29.30 passes between the upper and lower fixed cam followers 33.34 while being in the separation position N as shown in FIG.
The eccentric cam 31.3 for rolling down is driven to rotate.
2 also rotates from the non-rolling position n to the rolling position m, as shown in FIG. Then, the tip of the strip 11 is gripped by the upstream grip part 18 of the gripper 20.

In this state, the traveling table 16 continues to move along the guide rail 3, and the upstream gripping portion 18 of the gripper 20
The strip 11 gripped by the strip 11 is guided into the heating device 5 and heated while floating and supported in a non-contact state by blowing fluid against each device inside the heating device 5, and then subjected to a predetermined process. The plate is passed through a cooling device 6 and cooled.

When the gripper 20 passes between the pinch rolls 12 separated from each other in the vertical direction, the pinch rolls 12 move up and down to firmly press the strip 11 from above and below with a constant pressure, and the pinch rolls 12 grip the strip 11.
It is now possible to send it to the downstream side.

Thereafter, due to the movement of the traveling platform 16, the driving eccentric cam 29,30 passes the upper and lower positions of the central fixed cam follower 35 while being located at the proximity position M as shown in FIG. .30 is rotationally driven to the separation position N, and along with this, the eccentric cam 31 for lowering
．． 32 also rotates from the rolling position m to the non-rolling position n as shown in FIG. After the gripper 20 opens to release the tip of the strip 11, the gripper 20 moves upstream on the escape track X' together with the carriage 1B.

The strip 11 released from the gripper 20 is
It is fed downstream by the pinch rolls 12, passed through the priddle rolls 7, lightly rolled down by the skin pass mill 8, and wound up by the winder IO.

While winding by the winding machine 10 is progressing, the gripper 20 and the traveling table 16 are waiting at a predetermined position on the upstream side of the strip conveyance direction on the evacuation track X', When the unwinding of the strip 11 is completed, the conveying speed of the strip 11 is reduced to the required speed, and during this time, the coil formed by winding the strip 11 to be subjected to the subsequent heat treatment is transferred to the unwinding machine 3. Once installed, the unwinding of the subsequent strip 11 is started.

When the rear end of the preceding strip 11 is sent to a required position on the upstream side of the upper and lower fixed cam followers 33 and 34, the gripper 20 and the traveling platform 16, which were waiting on the evacuation track X', are driven by the chain 15 to remove the strip. At the point when the downstream gripping part 19 of the gripper 20, which is moved onto the conveyance line , the gripper 20 and the carriage 16 move in synchronization with the conveying speed of the preceding strip 11.

During this time, the succeeding strip 11 is being unwound at a speed higher than the conveying speed of the preceding strip 11, so that the leading end of the succeeding strip 11 is moved to the leveler 4.
The upstream gripping part 1 of the gripper 20 is moving in synchronization with the preceding strip 11 in the open state after passing through the
Sent during the 8th period.

When the leading end of the following strip 11 is fed between the upstream gripping portions 18 of the gripper 20, the conveying speed of the preceding strip 11, which had been reduced in speed up to that point, and the moving speed of the gripper 20 and the traveling platform IB are changed. is sped up to synchronize with the unwinding speed of the following strip 11.

After that, as in the case where the leading end of the strip 11 is guided as described above, when the driving eccentric cam 29.30 passes between the upper and lower fixed cam followers 33.34 while being located at the separation position N as shown in FIG. , drive eccentric cam 2
9.30 is rotationally driven to the proximity position M, and accordingly, the eccentric cam 31.32 for rolling is also rotated from the non-rolling position n to the rolling position m as shown in FIG. is gripped by the downstream gripping part 19 of the gripper 200, and the tip of the following strip 11 is gripped by the upstream gripping part 18 of the gripper 20.

In this state, the traveling platform 16 continues to move along the guide rail 13, and the rear end of the preceding strip 11 is held by the downstream gripping part 19 of the gripper 20 and is supported floatingly by the heating device. 5, the preceding strip 11 is heated in the high-temperature heating device 5 and becomes softer and more easily damaged than at normal temperature. In addition, the subsequent strip 11 gripped by the upstream gripping part 18 of the gripper 20 can also be prevented from touching the inside of the heating device 5 with respect to each device, etc. inside the heating device 5, as described above. It passes while maintaining the contact state and predetermined processing is performed.

Furthermore, the rear end of the preceding strip 11 and the leading end of the following strip are respectively gripped by the downstream gripping portion 19 of the gripper 20.
While being held by the upstream gripping section 18, the sheet is passed through the cooling device 6 and cooled.

When the gripper 20 passes between the pinch rolls 12, the pinch rolls 12, which had previously been firmly holding the preceding strip 11 from above and below with a constant pressure, pass between the pinch rolls 12.
are separated from each other in the vertical direction, and after passing through the gripper 20, are raised and lowered again to firmly press the subsequent strip 11 from above and below with constant pressure, making it possible to feed the subsequent strip 11 to the downstream side. .

Thereafter, due to the movement of the traveling platform 16, the driving eccentric cam 29,30 passes the upper and lower positions of the central fixed cam follower 35 while being located at the proximity position M as shown in FIG. .30 is rotationally driven to the separation position N, and along with this, the eccentric cam 31 for lowering
．． 32 also rotates from the rolling position m to the non-rolling position n as shown in FIG. After opening the rear end of the leading strip 11 and the leading end of the following strip II, the gripper 20 moves together with the carriage 16 on the evacuation track X' toward the upstream side.

The preceding strip 11 released from the gripper 20 passes through a priddle roll 7, a skin pass mill 8, and is wound up on a winding machine IO.
The subsequent strip 11 released from the strip 11 is sent downstream by the pinch roll 12 and passed from the prydle roll 7 to the skin pass mill 8.

When the preceding strip 11 is completely wound on the winder 10 to form a coil, the coil is carried out by a coil car (not shown), and then the subsequent strip 11 passed through the skin pass mill 8 is wound. It is wound up by a winding machine 10.

Thereafter, the same operation as described above is repeated, and slip 1
Heat treatment No. 1 is performed sequentially.

In this way, the rear end of the preceding strip 11 and the leading end of the following strip 11 are not joined as in the conventional method.
It becomes possible to process each coil of the strip 11, and the welding machine 2, louver device 11, flying shear 9, etc. shown in FIG. 9 are no longer necessary, and the total length of the equipment can be significantly shortened. .

Moreover, FIGS. 7 and 8 (a), (b), and (/\) show other embodiments of the present invention, in which the pinch roll 12 in the embodiment shown in FIG. 1 is omitted, and the cooling A prydle roll 7 is disposed immediately downstream of the device B, and the downstream end 13b of the guide rail 13 extending from the downstream position of the leveler 4 through the heating device 5 and the cooling device 6 is connected to the prydle roll 7.
At the same time, a portion of the guide rail 13 located in the path along which the shaft 37 of the roll 7a among the rolls 7a, 7b, and 7c constituting the priddle roll 7 is raised and lowered is configured to be detachable, thereby forming a detachable rail portion L3c. Furthermore, sprockets 14 are disposed at the upper and lower ends 13a and Hb of the guide rail 13, respectively. In addition, in the figure, 38 indicates an auxiliary presser roll.

In the other embodiments described above, the strip 11 held by the upstream gripping part 18 of the gripper 20, the heating device 5,
After passing through the cooling device 6, the roll 7 of the priddle roll 7 changes from the state shown in FIG. 8(a) to the state shown in FIG. 8(b).
When the sheet is passed between roll a and rolls 7b and 7c, roll 7
a and the removable rail portion 13c of the guide rail 13 are lowered, and the roll 7b is lowered.

7c rises and approaches the required amount, and then the auxiliary presser roll 3
8, 38 are pressed against the strip 11, and as shown in FIG.
), the strip 11 is passed through the priddle roll 7, and then the tip of the strip 11 is released from the gripper 20, passed through the skin pass mill 8 shown in FIG. It will be done.

In the case of the above other embodiments, the pinch roll 1
Since there is no need to install 2, the total equipment length can be further shortened.

It should be noted that the strip running equipment of the present invention is not limited to the above-described embodiments, and is not limited to strip heat treatment equipment, but can also be used in strip heat treatment equipment, such as coating equipment, which requires non-contact treatment of strips. Of course, various modifications can be made without departing from the gist of the invention, such as application to general equipment for surface treatment.

[Effects of the Invention] As explained above, according to the strip traveling equipment of the present invention, each coil of the strip is moved without joining the rear end of the preceding strip and the leading end of the following strip. This has the excellent effect of reducing the total length of the equipment by eliminating the need for a welding machine or looper device.
