されている。2. Description of the Related Art Conventionally, an article such as a coil wound with a steel sheet is packed with a wrapping stretchable synthetic resin packaging film on its outer surface for the purpose of protecting it from water and dust when storing and transporting it. This is commonly done. In particular, a large cylindrical article such as a steel sheet wound coil has a cylindrical hole in the center and is heavy, and for example, is disclosed in
As shown in Japanese Patent No. 294314, while a shuttle provided with a supply means for a stretch packaging film orbits on an endless track, the shuttle penetrates a cylindrical hole of a cylindrical object to be packaged which is supported by a cradle roll. A packing device is used in which the shuttle runs to pack not only the outer surface of the article to be packaged but also the cylindrical hole surface with a packaging film.

装置の新たな運転方法の開発が望まれていた。[0003] In such a packaging apparatus, the shuttle for pulling the packaging film has a structure of orbiting at a constant speed on the loop body. For this reason, a method of simply increasing the shuttle speed has been adopted in order to increase the efficiency of the packing work.However, if the shuttle speed is increased, the unwinding speed of the packaging film becomes large, and the film tension becomes excessive and the film tension becomes excessive. There is a problem that there is a phenomenon of cutting and there is a limit to increasing the shuttle speed,
To prevent film breakage, the shuttle speed should be reduced, but in this case there is a problem that packing efficiency is reduced, and at the same time the conflicting technical issues of improving work efficiency and preventing film breakage are satisfied. It has been desired to develop a new operation method for a packaging device that can be used.

る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. The drawing shows a case where a steel sheet wound coil, which is a cylindrical object W to be packaged, is packed with a packaging film F. In the drawing, 1 is a loop body forming an endless track, and 2 is a loop running on the endless track. Shuttle, 3
Is a cradle roll that supports the packaged object W, and the shuttle 2 is configured to penetrate through a cylindrical hole of the packaged object W supported by the cradle roll 3 while traveling around an endless track. The operation of the shuttle 2 for packing the object W to be packaged not only on the outer surface but also on the cylindrical hole surface with the packaging film F is described in Japanese Patent Application Laid-Open No. HEI 5-294314. The same is true.

In this way, it is possible to prevent the packaging film F from being cut on the entrance side and the exit side of the cylindrical hole surface of the article to be packaged W, and to control the high speed. This allows efficient packing without running out of film even when operated with a.

できることとなる。This is because, when the inventor runs the shuttle 2 at a constant speed and packs the packaging film F in the packaged object W, the packaging is particularly performed on the entrance side and the exit side of the cylindrical hole surface of the packaged object W. This is based on the finding that the phenomenon that the film F is cut occurs. That is, as shown in FIG.
(The size of the packaging film F before shrinkage is 20)
0 mm, and the smaller the numerical value is, the larger the shrinkage ratio (corresponding to the tensile force) is). This tendency becomes more remarkable when the traveling speed is increased. Therefore, if the speed of the shuttle 2 is controlled so as to be low when the shuttle 2 penetrates the cylindrical hole of the article W to be packaged, it is possible to prevent the packaging film F from being cut even when the whole is operated at high speed.

It is preferable to control at least the low-speed operation of the shuttle 2 at a speed reduced to 70% or less of the high-speed operation. In particular, when the high-speed operation of 200 m / min or more is performed, the low-speed operation is reduced to 50% or less. It is preferable to control the deceleration to the speed. Conventionally, when the shuttle 2 was traveling at a constant speed, the traveling speed was set to about 100 m / min so as not to cause film breakage. However, in the present invention, the traveling speed of the shuttle 2 in a high speed region is set to 250 m / min.
It can be set to min or more.

の制御手段を選択できることも勿論である。As shown in FIG. 2, the shuttle 2 has a supply means 21 for a packaging film F. The pre-tensioning rollers 22a and 22b and a group of tension-holding guide rollers 23 are used to feed the film with a constant tension. It is configured to supply. In the figure, reference numerals 24 and 25 denote wheels. The loop body 1 is sandwiched between the wheels, and is configured to run on a track by operation of a motor (not shown). As an example of the speed control method, in the illustrated example, a sensor S for detecting the position of the shuttle 2 is installed on the track, and the traveling speed of the shuttle 2 is controlled by timer control based on an output signal of the sensor S. It is like that. That is, in response to the output signal of the sensor S, the motor is rotated at high speed for a certain period of time to perform high-speed operation of the shuttle 2, and then the timer is controlled to perform low-speed operation of the shuttle 2 by rotating the motor at low speed for a certain period of time. By doing so, the packaging can be completed. Note that the speed control method is not limited to this, and, for example, the installation position of the sensor S is arbitrary, and it goes without saying that any control means other than the timer control can be selected.

い。As shown in FIG. 1, the packaged object W is supported by a pair of cradle rolls 3, and the packing operation is performed while being rotated in the axial direction by the rotation of the cradle rolls 3. Whole packaging film F
In this case, if the rotation speed of the cradle roll 3 is controlled in conjunction with the revolving speed of the shuttle 2, the rotation speed of the cradle roll 3 is controlled in accordance with the rotation speed of the shuttle 2. Cutting of the packaging film F on the delivery side is suppressed, and the overlapping margin of the packaging film F is constant, so that there is no waste and the packaging operation can be performed in a short time, which is preferable.

It is controlled to be driving and is made to run around,
As a whole, the shuttle 2 can travel around at high speed as compared with the conventional case, and the packing work can be greatly improved without occurrence of film breakage.
