Abstract

The utility model provides a paper separating mechanism, which comprises a sucker driven by an mechanical arm, wherein the mechanical arm drives the sucker to suck the uppermost paper from the upper surface of the stacked paper and translate the uppermost paper to an operation area; a brush is further arranged on one side of the upper surface of the paper stack, and hairs on the brush swing to the top of the paper stack from the side surface. The utility model discloses simple structure can share the paper effectively to the sucking disc can absorb the uppermost page of paper translation operation in the balanced position of paper.

Description

Paper separating mechanism

Technical Field

The utility model relates to a paper separating mechanism.

Background

At present, there are generally two situations of paper separation: one type of paper separation device is a paper separation device that separates the uppermost sheet of paper from the middle of a stack of sheets of paper for use (printing) in a paper cassette of a printer or the like. Another is to use suction cups to suck the uppermost sheet from a stack of sheets, which is common when using a robot to pick up sheets or other sheet material. In this way, the suction cups vacuum the uppermost sheet on top, the lower sheet generally does not transfer with the uppermost sheet due to its own weight, but sometimes the uppermost sheet and one or two of the lower sheets may not separate from the end-of-sheet due to electrostatic effects. Therefore, in order to provide a plurality of methods for separating paper, chinese patent publication No. CN 106629154B discloses a method for vacuum adsorption separation treatment of paper, which comprises:

arranging a certain included angle alpha between a suction disc opening of a suction disc and paper to be separated;

arranging the sucker above any corner of the uppermost layer of the paper to be separated;

it is right certain effort is applyed downwards to the sucking disc, so that the sucking disc pushes down the corner of the superiors' paper makes its atress after the paper of treating the separation warp the perk and produces certain angle beta, wherein: the magnitude of the acting force is calculated and obtained according to the thickness of the paper and the included angle alpha; assuming that the acting force is F1 and the paper thickness is T, F1 is lambda T alpha, wherein lambda is an adjusting coefficient and is 0.8-1.2; f1 is in units of kgf and T is in units of mm;

when the included angle alpha is consistent with the angle beta, applying vacuum suction to the suction disc to enable the uppermost layer of paper to be adsorbed on the suction disc; the magnitude of the vacuum suction force applied to the sucker is obtained by calculation according to the gram weight of the paper; assuming that the vacuum suction force is F2, the grammage of the paper sheet is G,

f2 is ω G, wherein ω is an adjustment factor and has a value of 0.006-0.009; f2 unit is kgf, G unit is G/m 2;

and when the suction disc presses the corner of the uppermost layer of paper in the paper to be separated, the suction disc moves 0.5 mm-1.0 mm towards the center of the paper to be separated, and the position is reset after the paper is adsorbed and separated.

Although the mode can realize paper separation, the paper separation mode adopting the sucking disc to suck the paper at present usually needs to adopt a mechanical arm to translate the paper to a working area, and the sucking disc cannot translate when one corner of the paper tightly sucks the paper.

SUMMERY OF THE UTILITY MODEL

The utility model discloses it can not be used by the arm translation to absorb the device that separates the paper from the paper one corner to draw the separation paper to present paper vacuum adsorption separation processing method, provides a paper separating mechanism.

The utility model discloses a realize that the technical scheme that its technical purpose adopted is: a paper separating mechanism comprises a sucker driven by a mechanical arm, wherein the mechanical arm drives the sucker to suck the uppermost paper from the upper surface of a stack of paper and translate the uppermost paper to an operation area; a brush is further arranged on one side of the upper surface of the paper stack, and hairs on the brush swing to the top of the paper stack from the side surface.

The utility model discloses simple structure can share the paper effectively to the sucking disc can absorb the uppermost page of paper translation operation in the balanced position of paper.

Further, the paper sharing mechanism comprises: the mechanical arm is driven by four symmetrically arranged suckers.

Further, the paper sharing mechanism comprises: two ends of one side of the upper surface of the paper stack are respectively provided with a brush.

Further, the paper sharing mechanism comprises: the paper stacking device further comprises a blowing device, and the blowing device blows air to the stacked paper from the opposite side of the arranged hairbrush. The present invention will be described in more detail with reference to the accompanying drawings and examples.

Fig. 3 is a plan view of embodiment 2 of the present invention.

Detailed Description

Embodiment 1, this embodiment is a feeding mechanism of a full-automatic stamping machine for stamping and printing a packing box of cosmetics, which is a paper separating mechanism, as shown in fig. 1 and fig. 2, in this embodiment, a paper-taking mechanical arm 200 of the stamping machine repeatedly takes paper from the top of a stack of paper 100 to a stamping table for stamping operation, and the mechanical arm 200 sucks the topmost sheet of the stack of paper 100 by using a suction cup 201, in this embodiment, in order to make the suction cup 201 suck the topmost sheet of packing box paper, the position where the suction cup 201 sucks the paper is set at a symmetrical position of the packing box paper, for example, when there is only one suction cup 201 on the mechanical arm, the paper-sucking position should be at the central position of the packing box paper, if two suction cups 201 are used, the paper-sucking positions of the two suction cups 201 are on a symmetrical line of the packing box, such as a vertical folding line or a transverse folding line of the packing box, thus, when the uppermost sheet is translated, the translation will be smoothly performed. In this embodiment, the brush 300 is disposed on the upper portion of the periphery of the stacked paper 100, the hairs 301 of the brush 300 extend to the upper portion of the stacked paper 100 irregularly, and some hairs 301 may extend between the sheets of the stacked paper 100. The brush of this embodiment is practically a bundle of hair, which is a brush for convenience of description, but is not limited to a brush, and other bundled hair may be used herein. In this embodiment, a blowing device is further included, and blows air to the stacked paper 100, and in this embodiment, the blowing direction blows air from the opposite side of the brush 300.

When the bronzing machine of this embodiment is tested, use wind to blow to fold paper and sucking disc and inhale paper and always appear heavy paper, for this reason adjust the wind speed many times still can not solve the problem, add the brush after folding paper top edge, do not appear the problem of heavy paper again through many times of tests, even actually solved this problem.

Embodiment 2, as shown in fig. 3, in this embodiment, four suction cups 201 are used under the robot arm 200, the four suction cups 201 are disposed at four corners of a square plane, and two brushes 300 are disposed at one side.
