Description

High speed paper lamination reverse loading device

The present invention relates to a device for loading and reversing the printed or cut paper (or paper) at the same time in a state in which a certain amount of paper (or paper) is stacked neatly. By repeating the discharging process at high speed and precision, the speed and accuracy of operation as well as the production speed are doubled. It relates to a high-speed paper reversing loading device.

Recently, the use of various printed materials such as various promotional materials, reports, and booklets is increasing, and processes that must be processed in large quantities in the process of producing and distributing such printed materials are increasing. On the other hand, various printed materials or coated papers are shrunk in one direction due to the characteristics of the paper (paper) itself, or the characteristics of the paper change depending on the effect of heat or friction generated during printing, resulting in bending in one direction, and corrugated cardboard Even in the case of corrugated cardboard, the shrinkage rate of the top and back surfaces is different, and in the case of printing, bending in one direction occurs under the influence of heat or friction generated during printing.

In the case of these various printed materials, coated paper, box paper, etc., when a large amount is loaded for distribution or production, the bending phenomenon in one direction is aggravated. , there are problems such as safety due to tilting and falling when loading in a large number.

In order to solve this problem, when a large amount of paper is loaded, the loading direction is reversed for each predetermined amount to alleviate the warping phenomenon. There is a problem in that the operation is not easy and the loading time and cost increase. In order to compensate for the above problems, an automatic reversing device is being actively developed, and as a prior art document that can be referenced in this regard, Korean Utility Model Registration No. 20-0325888 (Prior Document 1), Korea Publication Utility Model Publication No. 20-2008-0004812 (Prior Document 2) and the like are known.

Prior Document 1 is configured in the form of a table with an inclined upper surface by combining vertical and horizontal frames 110 and 120, and after coupling the driving drum 130 and the belt pulley 150 between the horizontal frames 120, the belt (140), the main body part 100 in which one side driving drum 130 and the driving motor 160 are coupled with a chain 161, and a clamping tool 240 on the horizontal frame 120 using a clamping member ( 210) is installed, but the driving unit 200 configured to rotate 180° by combining the reversing motor 230 and the chain 231, and the corrugated cardboard 400 transferred through the main body 100 are loaded with the driving motor 330 ) proposes an automatic reversing device for corrugated cardboard, characterized in that it is composed of a loading unit 300 to which the lifting plate 340 is coupled to the upper and lower sides by the

However, according to the preceding document 1, since the conveyor is continuously connected in the above process, it was difficult to stack several sheets of corrugated cardboard inside the pincher by the conveyor. There was a problem in that it could not return to its original position until it was out of the range of the fork, and since the movement of the following corrugated cardboard should be stopped while the pincher rotates, continuous production is difficult.

In Prior Document 2, a frame 11 of a certain height is woven, and in the lower portion of the frame 11, the rotation support 12 rises to a certain height and rotates 90° or more, and the frame 11 upper part In the rotation support 12, the cylinder 14 is fixed in parallel to the outside, and the rod of the cylinder 14 is provided with an automatic reversing device 10 having a structure in which the pusher 15 is fixed; a supply conveyor 30 installed at a higher position than when the pivoting support 12 is positioned under the frame 11; a roller feeding unit 20 having a structure in which rollers 21 and 21 ′ are installed respectively above and below at the same height as the conveying conveyor 40; the automatic reversing device (10); a transfer conveyor 40 installed parallel to the height at which the pivot support 12 is raised; The loading unit 50 presents an automatic reversing stacker installed in sequence.

However, according to the preceding document 2, a predetermined amount is supplied in units of stacked paper modules, and the supplied paper modules are alternately inverted up and down to automatically load, thereby preventing paper warpage and reducing the loading process time by automation. While there is an advantage of reducing costs, the above prior art has a disadvantage in that it is only configured to automatically load the paper modules by alternately inverting them up and down, and does not consider structural improvement that enables efficient space utilization.

In order to solve this drawback, the present applicant has proposed Korean Patent Publication No. 10-0753682, which supplies a certain amount of stacked paper modules according to a predetermined sequence, and alternately turns the supplied paper modules up and down and stacks them. and ejected automatically.

However, according to the above-described prior art of the present applicant, a certain amount is supplied in units of stacked paper modules, and the supplied paper modules are alternately stacked up and down to be stacked and automatically discharged, so that the stacking direction is reversed and the stacked paper is loaded. Although warpage occurrence is prevented and the loading process time is shortened by automation and the effect of reducing costs is pursued, there is still room for improvement in the reversing part that reverses/loads the paper, that is, the inversion part is one of the important design factors. There is room for improvement to secure process automation, such as showing limitations in the direction of increasing productivity as well as better speed and accuracy by improving it and not meeting expectations.
