Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a paper retainer attached to a paper feed port of a printing machine or the like.

[0002]

[Prior art]

 Paper is normally supplied to a printing machine or the like by a paper feeding machine separate from the printing machine and fed into the paper feeding port of the printing machine at high speed. Therefore, it is necessary to provide a means for preventing the paper sent at high speed from floating near the paper feed port of the printing machine, and ensuring that the paper can enter the paper feed port. In other words, a method is employed in which a pressing tool having a metal elastic plate is arranged near the paper feed port of the printing machine, and the elastic plate presses the paper.

[0003]

[Problems to be solved by the device]

 However, when the method of pressing the paper fed at high speed with the elastic plate made of metal is adopted, the contact with the elastic plate may cause scratches on the surface of the paper at the time of passage. If such scratches occur on the surface of the paper, it will be defective as a printed matter.However, in recent high-speed printing machines, as a result of mass printing in a short time, the presser foot There is a risk that a large amount of defective products will be generated in a very short time due to the defects of. In particular, with specially processed paper used for milk packs, sake packs, etc., the surface is easily scratched and the price is expensive, so the loss of a defective product is very large. It becomes a thing. In order to prevent such a phenomenon, recently, a metal plate surface is covered with a resin, but when such a structure is used, the wear state of the resin is always maintained. However, if a worn residual piece is pulled into the printing machine, it may damage the expensive printing machine itself. The present invention seeks to eliminate such drawbacks found in conventional configurations.

[0004]

[Means for Solving the Problems]

 The present invention relates to a paper retainer attached to a paper feed port of a printing machine or the like, and has a configuration in which a notch recess is formed in the center of the elastic plate on the front end side, and a rolling roller is arranged in the notch recess. This makes it possible to smoothly supply the paper, and at the same time, to prevent the occurrence of scratches on the surface of the paper when the paper comes into contact with the pressing tool.

【Example】

 One embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the paper retainer main body 1 is attached to the rear end side in the vicinity of a paper feed port 16 of a printing machine 14. The elastic plate 2 is attached to the tip of the bar 10 having the portion 12, while the rolling roller 3 is arranged on the tip of the elastic plate 2.

As shown in FIG. 2 and FIG. 3, the attachment portion 12 to the printing press 14 has a fastening tool 13 arranged above the metal block 11 having a “U” shape, and at the lower portion thereof, The base end portion of the bar 10 is integrally attached, and after the concave portion of the metal block 11 is fitted into the frame portion of the printing machine 14, the tightening tool 13 is rotated. Thus, the whole structure can be fixed.

As shown in FIGS. 2 to 4, the elastic plate 2 is formed with a notch concave portion 6 having a width in which the rolling roller 3 can be arranged in the center portion on the tip end side, and rolling roller recesses are formed on both side portions thereof. Mounting portions 5 and 5 for supporting and fixing both side portions of the shaft rod 4 for supporting the rail 3 are formed, and a bending portion 8 is further provided at a middle position of the plate surface portion, and a rear portion is further provided. Has a screw hole 7 ・ 7 formed therein. By inserting a screw 9 ・ 9 into the hole 7 ・ 7 and screwing the screw shaft portion thereof into the screw hole 17 ・ 17 formed in the bar 10, the elasticity is improved. The plate 2 can be attached and fixed to the bar 10.

The rolling roller 3 is formed by arranging a plurality of bearings in series and inserting the shaft rod 4 into the central portion thereof. When mounting the elastic plate 2 on the shaft rod 3, This is done by arranging both end portions of 4 on the mounting portions 5 formed on the elastic plate 2 and then fixing them integrally by spot welding.

The above is the case where the rolling roller 3 is configured by arranging a plurality of bearings in series, but by inserting the shaft rod 4 into the cylindrical body in a rotatable state, It is also possible to form.

[0010]

[Effect of device]

 The paper retainer main body 1 according to the present invention is configured as described above, and is configured to press the paper at the time of paper feeding by the rolling roller 3 attached to the elastic plate 2. It is possible to completely prevent scratches from being generated on the surface of the paper at the time of passage, and to smoothly supply the paper sent from the paper feeder 15 to the paper feed port 16 of the printing machine 14 or the like. There are advantages.
