Abstract

The present invention relates to a loading system of a printing apparatus, and in particular, by using a lever rotated in two opposite directions by receiving a paper being conveyed through a transfer cylinder, the loading speed is increased by elliptical movement close to linear motion. A loading and conveying system of a printing apparatus that can be increased.

Description

Feeding and loading system of printing equipment {Loading system for printing machine}

The present invention relates to a conveying and stacking system of a printing apparatus, and more particularly, to stack a printing apparatus capable of increasing a stacking speed by receiving paper conveyed through a transfer cylinder and stacking it through a trajectory of an elliptic motion close to a linear motion. And a transfer system.

There are many printing devices. Often, the bulky printing apparatuses used for home or office use are widely used, but large business apparatuses are used in the case of large business. The present invention relates to a large printing apparatus.

Referring to Fig. 1, a conventional printing apparatus is schematically shown. The ink unit for supplying ink of various colors on the upper part of the cylinder 12 is omitted to avoid the complexity of the drawing. As shown in Fig. 1, the printing apparatus starts to operate from a feeder unit 10 to which paper is loaded and fed. The paper from the feeder unit 10 passes through the first feeder cylinder 14 and then through the first impression cylinder 13, where the first color is printed, which is the plate cylinder ( 11) and the blanket cylinder 12 (blanket cylinder) (12) to transfer the ink to print between the impression cylinder. The printed paper is transferred to another impression cylinder by a transfer cylinder 15 between the impression cylinders 13 so that the second color is printed and continuously printed in the same way, followed by the last impression cylinder and then transfer Transferred to the chain (20). At this time, the gripper 15a is installed between the impression cylinder 13 and the transfer cylinder 15 to grab and transport the paper.

The gripper 20a is also installed on the transfer chain 20 to grab paper and transfer it along the transfer chain 20, and the printed paper is transferred along the transfer chain 20 to the dryer 21 installed inside the chain. Dried and then loaded into a delivery unit 30.

However, the printing device according to the prior art is printed at a high speed through the cylinder and is conveyed to the chain device to dry the conveyed paper. The chain device is limited in speed due to stability or other reasons, so no matter how fast and fast the cylinders are. Even if it can rotate, the movement of the heavy chain device is changed from a linear motion to a rotational motion, and again the rotational motion is changed to a linear motion, there is a problem that can no longer increase the printing speed.

In addition, in order to solve this problem, there is a method of extending and transferring the transfer cylinder instead of the chain device. However, this method also has a problem in that the paper conveyed through the transfer cylinder is always in a circular motion, which is difficult to load, and when the paper is thick, the paper is unfolded and noise makes loading and conveying difficult.

The present invention has been made to solve the problems of the prior art described above, when loading the paper transmitted from the transfer cylinder to convey the paper using two levers so that the trajectory of the paper to perform an elliptic motion close to a straight line Its purpose is to provide a loading and conveying system for a printing apparatus.

The stacking system of the printing apparatus according to the present invention includes a rotary lever fixed and rotated so as to be rotated in a predetermined frame, a gripper lever installed on one side of the rotary lever and rotated in a direction opposite to the fixed lever, and the gripper. It is characterized in that it comprises a gripper which is installed at the free end of the lever and rotates with the gripper lever to convey the paper transferred from the transfer cylinder.

Here, the rotary shaft of the rotary lever and the rotary shaft of the gripper lever is characterized in that the restraint.

The stacking and conveying system of the printing apparatus according to the present invention provides an effect of increasing the printing speed regardless of the thickness of the paper because the paper trajectory is loaded along an elliptic trajectory close to a straight line.

1 is a schematic configuration diagram of a printing apparatus according to the prior art.
2 to 3 are schematic configuration diagrams of a conveying and stacking system of a printing apparatus according to the present invention, and show states at various positions.
5 is a perspective view of a conveying and stacking system of a printing apparatus according to the present invention shown in FIG.

2, there is shown a schematic configuration of a loading system according to the present invention. The printed paper is conveyed through the transfer cylinders 110 and 120 as in the prior art. The grippers 111 and 121 are installed in the transfer cylinders 110 and 120, respectively, to receive paper each time the grippers 111 and 121 meet. Since this is a prior art, the details are omitted here.

The paper 100 held by the gripper 121 of the transfer drum 120 is transferred to the stacking gripper 141 installed at the free end of the gripper lever 140. Then, it is transported along the trajectory E of the loading gripper 141 indicated by the dotted line and then loaded.

2 and 5, the idle lever 130 is rotatably installed at a side of the paper to be rotated about a fixed shaft 130a at a predetermined position. The idle lever 130 is rotated in the counterclockwise direction with reference to the drawing about the fixed shaft 130a. The idle lever 130 is installed on both sides of the place where the paper is loaded. Rotating levers 140 are rotatably installed around the rotating shaft 140a on each idle lever 130, and both ends of the gripper 141 are provided at the free ends of the respective rotating levers 140. The rotating lever 141 installed in this way is rotated in the opposite direction to the idle lever 130, that is, clockwise in FIG.

Here, the rotating shaft 140a of the rotating lever 140 is inherited to be constrained with the fixed shaft 130a of the idle lever 130 by a gear or a belt. Therefore, the rotation lever 140 rotates at the same ratio as the idle lever 130 rotates, and thus the elliptic trace E of the dotted line is drawn. This elliptic trajectory (E) has an effect almost like a straight line feed to the paper feed.

3 illustrates a state in which the gripper 141 of the rotating lever 140 receives paper from the gripper 121 of the transfer drum 120. At this time, the paper is transferred from the transfer drum 120 toward the rotating lever 140.

The paper conveyed in FIG. 3 is transported along the trajectory E and comes to the position shown in FIG. 4 to be loaded.

After loading, the gripper 141 of the rotation lever 140 is rotated along the elliptical trajectory to the position of FIG. The gripper 141 continuously stacks the paper while continuously conveying the elliptic trajectory E. FIG. Of course, the idle lever 130 is continuously rotated in the opposite direction.

Since this operation makes the elliptical track E using two levers 130 and 140 rotated opposite to each other, it is preferable that the two levers 130 and 140 balance their respective weights.
