Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a side wrapping paper cutting device for cutting side wrapping paper from a base paper used in a roll side wrapping device, and a side wrapping paper cutting device for cutting the side wrapping paper from a base paper, and a side wrapping paper cutting device for cutting the side wrapping paper from a base paper to be used in a roll side wrapping device. The present invention relates to a side wrapping paper preparation device.

(Prior Art) Conventionally, to prepare side wrapping paper used in a roll side wrapping device, an operator manually cuts out a large number of different types of side wrapping paper with different radii on a side wrapping paper preparation trolley in advance. Laminate sheets of paper with the same radius and line them up in a row, and each time each roll to be wrapped is wrapped, the side wrapping paper with a predetermined radius is attached to the packaging device by suction, depending on the radius of the roll to be wrapped. This was done by moving the board along with the cart to the side wrapping paper preparation position (for example,
0-144588).

(Problems to be Solved by the Invention) However, in the conventional technique in which a worker prepares a large number of side wrapping papers on a trolley in advance, the following problems occur.

In other words, when wrapping the side of a roll, it is necessary to use a circular side wrapping paper with a radius that matches the radius of the roll to be wrapped for effective wrapping without degrading the packaging quality. It is difficult to accurately cut out and prepare in advance a large amount of side wrapping paper with an optimal radius corresponding to the roll to be wrapped. Furthermore, the loading area of the trolley is limited, and the types of side wrapping paper that can be placed on it are limited. Therefore, it is virtually impossible to prepare each side wrapper with an optimum radius on the trolley in advance. Therefore, if the side wrapping paper prepared on the trolley is not suitable for the radius of the roll to be wrapped, the worker should prepare side wrapping paper with the required radius each time and replace it with the side wrapping paper placed on the trolley. It has to be replaced, which puts a heavy burden on the worker. The radii of the rolls to be wrapped that are processed by packaging equipment tend to be diversified, but it is difficult to deal with this. Since it is necessary to cut and prepare a large number of sheets, it is necessary to store the side wrapping paper in consideration of preventing deterioration of quality due to stains, moisture, etc. 6 It is also necessary to transport it from the storage location to the packaging device.

Further, if the rolls to be wrapped which require prepared side wrappers are interrupted for a long period of time, the prepared side wrappers may be wasted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a side wrapping paper cutting device that can accurately cut side wrapping paper of a required radius from a base paper at the appropriate time.

In addition, it is not necessary to prepare a large number of side wrapping papers with various radii in advance at the side wrapping paper preparation position for the wrapping device on the side of the roll. It is an object of the present invention to provide a side wrapping paper preparation device for a packaging device that can be quickly prepared each time.

Another object of the present invention is to provide a side wrapping paper cutting device that can automatically adjust the cutting radius according to the radius of the wrapping material.

(Means for Solving the Problems) Therefore, in order to achieve the above object, the side wrapping paper cutting device of the present invention has a blade that can be displaced in the cutting radial direction, and has a relative relationship between the blade and the base paper. A cutting device that cuts the base paper into a circular shape as side wrapping paper by a rotating motion, a base paper supply mechanism that unwinds the base paper of the side wrapping paper from the base paper roll and supplies it to the cutting device, and and a positioning mechanism for changing the position of the cutter.

Further, the side wrapping paper preparation device of the present invention is arranged near the side wrapping paper preparation position in the side wrapping paper preparation device for preparing the side wrapping paper used in the roll side wrapping device at the side wrapping paper preparation position. The above-mentioned side wrapping paper cutting processing device, a base paper remaining removal mechanism that removes the remaining portion of the cut base paper from the cutting device, and a side wrapping paper that transfers the side wrapping paper obtained by cutting the base paper to a side wrapping paper preparation position. A transfer mechanism is provided.

Further, the side wrapping paper preparation device may include an automatic positioning control device that instructs the positioning mechanism to determine the cutting radius of the cutter based on the aspect ratio signal from the wrapped roll radius detection device.

(Function) The base paper is rewound from the base paper roll by the necessary length when necessary by the base paper supply mechanism, and is supplied to the cutting device.

Further, the blade of the cutting device is positioned by a positioning mechanism at a position that provides a necessary cutting radius according to the radius of the roll to be wrapped. Then, the base paper transferred to the cutting device is cut into a circular shape by a cutter, resulting in side wrapping paper having a radius suitable for the roll to be wrapped.

The side wrapping paper cutting device cuts side wrapping paper from the base paper into a side wrapping paper having a radius that matches the radius of each roll to be wrapped each time each roll to be wrapped is supplied to the wrapping device on the side of the roll. Then, the side wrapping paper is separated from the remaining portion of the original paper and prepared at the side wrapping paper preparation position by the functions of the base paper remaining removal mechanism and the side wrapping paper transfer mechanism.

(Example) Next, an example of the present invention will be described with reference to the drawings.

3 is moved up and down by the drive of a fluid pressure cylinder device 18 provided on the stand 12. When the support arm 13 is lowered, the press roll 14 is pressed against the support roll 10, and the press shaft 5 is pressed against the center support shaft 10.

As shown in FIG. 4, this cutting device 3 sandwiches the central part of the base paper 2, which is a rectangular piece of paper, between a center support shaft 15 and a presser shaft 16, and cuts the vicinity of the cut point of the base paper 2 as required. The base paper 2 is sandwiched between the support roll 10 and the pressure roll 14 which are placed at the position of , and the support roll 10 is rotationally driven by the drive mechanism 11 shown in FIG. The base paper 2 is pressed against the knife 6 by a pressure roll 14 and cut into circular shapes. As described above, since the center support shaft 15 is in the direction of movement of the knife 6, the knife 6 can be displaced in the cutting radial direction. Accordingly, the cutting device 3 can change the cutting radius by displacing the knife 6. The press roll 14 is also movable in the cutting radial direction.

As shown in FIG. 3, the positioning mechanism 7 for changing the position of the cutter 6 includes a screw shaft 19 that is parallel to the rail 8 and that is screwed into the lower part of the movable body 9. It consists of a motor 20 that rotates and drives. And motor 20

The base paper supply mechanism 5 unwinds the strip-shaped base paper 2a from the base paper roll 4 supported by the support device 23 via a guide roll 26, a curl breaker 27, and a guide roll 28 by a rotatably driven ratio roll 24 and a nip roll 25. , a rewinding mechanism 29 that feeds out the paper to the cutting device 3, a known transverse cutting mechanism 30 that cuts the strip-shaped base paper 2a fed out from the rewind mechanism 29 in its width direction, and the base paper 2 that has been cut into paper pieces. and a base paper transport mechanism 31 that transports the paper to the cutting device 3. In this case, the base paper conveyance mechanism 31 includes two known suction conveyors 32 and support plates 33a, 33b, and 33c, as shown in FIG. Note that the support plate 33a33b is divided into left and right sides to enable displacement of the cutter 6 and the support roll 10.

The suction conveyor 32 includes a circulation belt 32b with suction holes around a suction box 32a, and generates a negative pressure inside the suction box 32a using an unillustrated blower or the like to adsorb the base paper 2 while circulating the circulation belt 32b. It is now possible to transport. They are arranged in a direction intersecting the displacement direction of the knife 6 and on both sides of the central support shaft 15 so as not to hinder the movement of the knife 6.

To obtain the side wrapping paper j, strip the base paper 2 from the base paper roll 4.

As a result, during cutting, the blade 6 and the base paper 2, which are supported at a fixed position, rotate relative to each other about the central support shaft 15, and the base paper 2 is cut into a circular shape as the base paper 2 rotates. Thereafter, the fluid pressure cylinder device 18 is activated, and the support arm 13 is raised and put on standby.

Such a cutting device, which cuts the base paper while rotating it using a rotatably driven support roll, occupies a small space and is therefore advantageous for installing a conveyance mechanism such as a suction conveyor or other mechanisms. Note that between the center support shaft 15 and the presser shaft 16 and between the support roll 10 and the presser roll 1.

As shown in FIG. 5, the interval adjustment mechanism 40 includes a screw shaft 44 having a right-hand thread and a left-hand thread, which is rotationally driven by a motor 43 capable of forward and reverse rotation. The threaded part of the screw shaft 44 is screwed into one suction conveyor 38, and the other threaded part is screwed into the other suction conveyor 38. When the screw shaft 44 is driven by the motor 43, both of them are screwed together. The suction conveyors 38 approach and move away from each other by the same amount at equal distances on the left and right with the center support shaft 15 as the center.

(Effects of the Invention) According to the side wrapping paper cutting device of the present invention, side wrapping papers with various radii can be obtained in a short time. In addition, the side wrapping paper can be accurately cut out without causing individual differences.

Further, according to the side wrapping paper preparation device of the present invention, the base paper is sent out from the base paper roll for each wrapping of the side surface of the roll to be wrapped,
Since the side wrapping paper is cut out with a radius suitable for the radius of the roll to be wrapped, even if the radius of the roll to be wrapped changes, the side wrapping paper with the optimum radius can be obtained each time. Therefore, there is no need to prepare in advance by cutting a large number of wrapping papers of several types with different radii. Also, there is no need for a place to store a large amount of side wrapping paper. There is also no need to worry about wasting a large amount of the side wrapping paper prepared in advance. Further, the labor required by the operator for preparing the side wrapping paper can be significantly reduced. Furthermore, it is possible to cope with the diversification of the radius of the rolls to be packaged processed by the packaging device, and the quality of packaging is also improved.

In addition, if the positioning mechanism is equipped with an automatic positioning control device that commands the cutting radius of the cutter based on the detection signal from the measuring device for the radius of the wrapped roll, the cutting radius can be automatically adjusted according to changes in the radius of the wrapped roll. Can be done.
