BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a print roll attaching / detaching apparatus, and more particularly, to a print roll attaching / detaching apparatus for inserting a print roll into / from a narrow space between printing apparatuses.

In recent technology for printing various patterns, a paper (or a film) is inserted into a printing apparatus, and printing is performed on a paper (or film) surface using a printing roll on which a base pattern is formed. . At this time, if the pattern to be printed on the paper (or film) is changed, or if the printing roll is broken, the printing roll having the desired pattern should be replaced.

However, in the past, in order to replace the printing roll, a person was directly inserted between the printing apparatuses, and the printing roll was taken out by hand and replaced. However, the printing apparatuses are spaced apart from each other by a distance of about 1 to 1.5 m, which is a narrow space for the operator to enter and work, and since the weight of the printing roll is up to about 50 kg at most, There is a problem that an operator is liable to be injured. In addition, when the operator drops the printing roll while swapping a heavy printing roll, or when it strikes another device, the printing roll often breaks easily. Particularly, the printing roll has a precise pattern, and if a fine scratch (scratch) is applied to the printing roll, the printing roll pattern is broken and a problem that it can not be used occurs.

In order to solve such a problem, an apparatus for replacing a printing roll in Japanese Patent No. 2582679 ("a printing roll changing apparatus of a printing press ", issued November 21, 1996, hereinafter referred to as prior art) is disclosed. More specifically, the prior art discloses a technique in which a printing roll changing apparatus of a printing press is inserted into a narrow space of a printing apparatus, and a printing roll is detachably attached using a multi-joint manipulator and a hand unit.

However, the above-mentioned prior art has a problem that when the heavy printing roll is lifted, it falls due to the eccentric weight of the printing roll.

Therefore, in recent years, a need has arisen for a print roll attaching / detaching apparatus which is inserted into a narrow space between printing apparatuses and which is easily replaced without breakage of the printing roll, and is not fallen by the eccentric weight of the heavy printing roll .

The first and second frames 200 and 200 'are provided at both upper ends of the pedestal 100 and are formed at a predetermined height in the upper direction.

The rotary shaft 210 is provided with a hinge part 220 having both ends connected to the first and second frames 200 and 200 'by a hinge. The first and second frames 200 and 200' Connect.

The first and second supports 300 and 300 'are spaced apart from the first and second frames 200 and 200' by a predetermined distance on the rotation axis 210 and are formed at a predetermined height in the upward direction. The first and second supports 300 and 300 'may further include a connection frame 301 connecting upper portions of the first and second supports 300 and 300'. The connection frame 301 serves to prevent the first and second supports 300 and 300 'from being rotated, and to improve robustness so that the first and second supports 300 and 300' are not distorted.

The first electric driving part 310 is connected to the first and second supporting parts 300 and 300 'by the rotating shaft 210 and is driven to rotate the first and second supporting parts 300 and 300'. At this time, a reduction gear 211 is further provided on the rotation shaft 210, and the reduction gear 211 is connected to the first electric drive unit 310. The reduction gear 211 rotates by the first electric drive unit 310 and transmits a rotational force to the rotation shaft 210 with a large force. The hinge unit 220 is further provided with a recliner to limit the rotation of the first and second supports 300 and 300 'due to the weight of the printing roll. More specifically, the first electric drive unit 310 operates to rotate the reduction gear 211. The reduction gear 211 transmits a large rotational force to the rotating shaft 210 so that the first and second supporting members 300 and 300 'can be easily rotated clockwise or counterclockwise with respect to the hinge unit 220 Tilt. However, the rotational force transmitted from the eccentric weight of the detachably attached printing roll to the first driving unit 310, as opposed to the rotational force transmitted from the first electric driving unit 310 to the first and second supporting rods 300 and 300 ' The deceleration gear 211 and the first electric drive unit 310 are controlled by the recliner provided in the hinge unit 220 so that the first and second supports 300 and 300 ' Thereby preventing breakage of the battery.

4, the first and second supporting members 300 and 300 'are inclined from the first driving unit 310 with respect to the hinge unit 220, A printing roll eccentric from the attaching / detaching device is mounted. At this time, as the position adjusting body 402 of the position adjusting part 400 is moved upward, the rotation angle becomes larger and the eccentric distance becomes longer, so that the rotation moment is more largely applied to the printing roll, There is a risk of falling easily. To prevent this, the weight 320 is required to have an opposite rotational moment equal to or greater than the rotational moment generated from the eccentric printing roll. More specifically, as shown in FIG. 4, the distance from the virtual reference line perpendicular to the hinge unit 220 to the printing roll is l1, the weight of the printing roll is P1, and the weight 320 And the weight of the heavy material 320 is P2, the moment M1 of the printing roll becomes P1 x l1, and the moment M2 of the heavy material 320 becomes P2 x l2. At this time, when the moment M2 of the heavy object 320 is equal to or larger than the moment M1 of the printing roll, the printing roll attaching / detaching apparatus does not fall. In order to satisfy this requirement, M1 < M2 must be satisfied, and since the hinge portion 220 of the first and second supports 300 and 300 'is positioned at the lower center of the center, P2 is heavier than P1 because? 2 is shorter than? do. That is, it is preferable that the weight P2 of the heavy object 320 is formed to be heavier than the maximum weight P1max of the printing roll to be detachably attached.

The rail 321 is provided at the upper end of the pedestal 100 and the lower portion of the first and second supports 300 and 300 ' As shown in Fig. The rail 321 is connected to the lower end of the heavy object 320 so that the heavy object 320 can be moved by a predetermined length in a direction in which the lower portion of the first and second supports 300 and 300 ' do.

3, when the upper part of the first and second supports 300 and 300 'rotates the eccentric distance l1 generated according to the height of the printing roll to be attached and detached, And the lower portion of the first and second supports 300 and 300 'is automatically rotated along the rail 321 by a distance l2 that is equal to M1 M2. That is, the weight 320 prevents the printing roll attaching / detaching apparatus of the present invention from being inclined due to the eccentric weight of the printing roll when the first and second supporting stands 300 and 300 'are inclined to lift the printing roll do.

4, the position adjusting unit 400 is provided on the first and second supporting members 300 and 300 'and moves in the vertical direction of the first and second supporting members 300 and 300' .
