Abstract

PURPOSE:To depress papers without being damaged and therefore to make it possible to smoothly feed papers, by holding papers at both sides by means of belts in the stacking direction thereof so that the belts are made to travel to depress the papers, thereby the papers are allowed to pass through a gap one by one. CONSTITUTION:A belt 20 is stretched between pulleys 22, 22 supported to a support plate 21 at the front end of a guide plate 18, vertically extending with its entirety, and a leaf spring 23 attached to the guide plate 18, for pressing the belt is arranged in the inner peripheral section of the belt 20, thereby the belt 20 is pressed against the front side face of stacking papers 12. Further, a motor coupled to the pulley 22 drives the belt 20 which therefore, depresses the stacked papers 12 while the belt slips on one side end face of the papers 12. Accordingly, even if any one of the papers warps, the paper 12 is held between two belts 20, 20 at both sides o the paper and is therefore depressed. Then, the papers are fed out through a gap at the lower end of a stopper plate 14 by means of a belt conveyor 11, one by one from the lowest layer paper. With this arrangement the papers are fed out smoothly, a without the papers being damaged.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper feeding device used in a box making machine for manufacturing paper boxes to feed paper cut into a predetermined shape to processes such as folding, gluing, etc.

This type of paper feeding device generally places a stack of paper on a belt conveyor, the front end of the stack of paper contacts a stopper plate, and the paper passes through the gap at the bottom of the stopper plate one by one to be sent out. is configured to do so.

In this paper feeding device, if a piece of paper is warped, it will not pass through the gap at the bottom of the stopper plate properly, resulting in a malfunction. Therefore, the stopper plate is provided with a fishing wheel pole film, and the paper is slightly laminated with the fishing wheel. A device has been devised in which the paper is pushed down by the hook of a fishing wheel.

With this device, the hook of the fishing wheel presses against the surface of the paper, which can damage the product.

Therefore, the present invention seeks to realize a paper feeding device that presses down paper without damaging the convex surface and operates smoothly.

That is, the paper feeding device of the present invention is characterized in that the stacked papers are held by belts from both sides, and the belts are run to push down the papers.

The present invention will be specifically described below with reference to illustrative embodiments.

In this paper feeding device 10, 11 is a belt conveyor, 12 tons of paper are stacked on top of this, and the rear end is held by a hook 13 and placed thereon. Reference numeral 14 denotes a stopper plate, which is attached to a bar 15 that crosses over the belt conveyor 11, and is brought into contact with the front end of the stacked papers 12 extending vertically. A gap 16 is provided between the lower end of this stopper plate 14 and the belt conveyor 11 to allow two sheets of paper 12 to pass one by one. Further, in front of the stopper plate 14, a roller 17. 12 tons of paper that has passed through the gap 16 with... - Belt conveyor 1
Press it to 1. Reference numeral 18.18 denotes a guide plate, which is attached to a working frame 19.19 in contact with both sides of the stacked papers 12. Reference numeral 20 denotes a belt, which is stretched over the boots IJ 22 and 22 supported by the support plate 21 at the front end of the guide plate 18, and extends vertically as a whole. A plate spring 23° attached to the guide plate 18 and pushing the belt 20 is provided on the inner circumference of the belt 20, so that the belt is pressed against the front side of the stacked papers 12. . belt 2

Since this paper feeding device has a configuration of 10 Fi or more, even if the paper 12 is warped, the stacked paper 12 is held down from both sides with the bell) 20. The belt conveyor 11 is delivered one by one through the gap 16 at the lower end of the stopper plate 14.
is pushing down the paper while sliding along the side edges of the paper, but the bell)
It is also possible to install a torque limit mechanism in the dynamic system to push down the paper without the belt slipping.

As is clear from the above embodiments, in the paper feeding device of the present invention, the belt holds the paper from both sides and presses it down, so even paper with a single warp can be smoothly fed without damaging the surface of the product. I can do it.

Third, the device of the present invention can be used in combination with a conventional fishing wheel, and even if the paper is large, it can be pressed down well and sent out smoothly.

At this time, the force applied to the fishing wheel can be made sufficiently small to reduce the occurrence of scratches.
