Abstract

PURPOSE:To convert the direction of feeding sheets of paper without damaging the sheets with the sheets only inserted through an inserting port, by constituting a straight section so that the sheets are fed erected on a transport belt and a direction converting section so that the sheets are sandwiched between a main roller and a sub-roller and the sheets are forcibly transported while being sandwiching between belts after the conversion of the direction. CONSTITUTION:A sheet of paper is inserted into an inserting port 1 on the upper surface in the erected position and dropped onto a rotating belt 4. Then, the sheet is sent to a direction converting section by sheet guides 5, 5' provided left and right of the belt 4 without falling down left and right. The direction converting section consists of one main roller 6 and a plurality of sub-rollers 7 located around the main roller 6 to press the sheet against the main roller 6 and rotating to send it along the circumference of the main roller 6. As a result, the sheet is sandwiched between the main roller 6 and the first sub-roller 7 to be sent along the circumference of the main roller 6. The sheet sent from between the finally located main roller 6 and the sub-roller 7 is sent into a direction converting section sheet guide 14 and then the sheet is pinched by forced transport belt 9 to be sent to an outlet 2.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an improvement in a paper feeding mechanism.

[Summary of the invention]

In the straight section where the paper first passes, the paper is placed on the conveyor belt, and the friction between the two sheets of paper and the conveyor belt feeds the paper in the straight direction.At the direction change section, the paper is sandwiched between the main roller and the sub roller.
After changing direction, the paper was sandwiched between the belts and forced to be conveyed.

[Conventional technology]

A conventional paper feeding mechanism is shown in FIGS. 3 and 4. FIG. 4 is a general view, and FIG. 3 is a plan view with the top cover removed.

The conventional paper feeding mechanism includes a paper insertion slot 119, a paper conveyance belt 12° roller 13, as shown in FIGS. 3 and 4. Direction change section paper guide 14. According to this method, it consists of a paper guide 15, 15', two paper insertion slots 11, and a paper transport belt 12 for rotating the paper. When the paper is dropped, the paper guides 15°15' provided on the left and right sides of the belt will keep the paper from falling to the left.
Paper and paper conveyance belt 1 while standing on paper conveyance belt 12
It is carried by the frictional force of 2. When the paper is conveyed to the direction change section, it is drawn in by the rollers 13, pushed out from the direction change section paper guide 14, and then rides on the paper conveyance belt 12 again to be conveyed along the straight section.

[Problem to be solved by the invention]

The conventional technology has the drawback that the paper gradually becomes static electricity during transportation, and after changing direction, it sticks to the paper guide and comes to a standstill, causing a paper jam.

The present invention aims to solve the above-mentioned drawbacks.

[Means to solve the problem]

In order to achieve the above object, the present invention sends the paper upright on a conveyor belt in the straight section, sandwiches the paper between the main roller and sub roller in the direction change section, and then sandwiches the paper between the belts after the direction change. 9 forcibly conveyed.

[Effect]

To explain the operation of the present invention, nine pieces of paper are inserted into the insertion slot on the top surface and dropped onto a belt rotating nine times.

Paper guides installed on the left and right sides of the belt prevent the paper from falling to the left or right (it is fed to the direction change section.The direction change section is 1
It consists of two main rollers and a plurality of sub-rollers that are positioned around the main roller and rotate to press the two sheets of paper against the main rollers and feed them around the circumference of the main rollers. The paper is sandwiched between the main roller and the first sub-roller, and is fed along the circumference of the main roller.

Then, it is sent out from between the main roller and sub roller located at the end and fed into the direction changing section paper guide. Thereafter, the paper is sandwiched between multiple forced conveyance belts 9 and the paper is forcibly conveyed to the exit.

〔Example〕

FIGS. 1 and 2 show one embodiment of the present invention, with FIG. 1 being a plan view showing the internal mechanism thereof, and FIG. 2 being a general view of the paper feeding mechanism.

■ is paper insertion slot, 2 is paper outlet, 3 is paper conveyance roller, 4
is the paper conveyance belt, and 5.5' is the paper guide.

6 is a main roller, 7 is a sub-roller, 8 is a paper guide in the direction change section, 9 is a conveyor belt, and 11 is a frame 0 To explain its functions, a paper conveyance roller 3 is attached to the frame 10, and 9 paper The conveyance roller 3 is rotated by a motor or the like, and the paper conveyance belt 4 is attached to the paper conveyance roller 3 which is rotated by a motor or the like.
The paper conveying belt 4 is rotated by frictional force with the paper conveying roller 3.

Paper guides 5 and 5' are provided on the left and right sides of the paper conveyance belt 4. The dimensions of the paper guides 5 and 5' are set so that the paper between the paper guides 5 and 5' does not fall down and the paper does not get jammed.

A direction change section paper guide 8 is provided at the entrance of the direction change section, so that the main roller 6 and sub roller 7 can easily pull in the paper.

When paper is dropped from the paper insertion slot 1 onto the rotating paper conveyance belt 4, the paper remains standing on the paper conveyance belt 4.

The paper is transported by the frictional force between the paper and the paper transport belt 4.

The paper is conveyed at high speed and accurately along the straight section made up of the paper conveying belt 4 and the paper guides 5 and 5' without falling to the left or right by the two paper guides 5 and 5'. When carried to the direction change section,
The paper entering from the direction changing section paper guide 8 is drawn into the main roller 6 and sub roller 7, the direction is changed to the desired angle by a plurality of side rollers 7, and the direction changing section paper guide 8 is also pushed out by the main roller 6 and sub roller 7. At the same time, they are sandwiched between a plurality of paper forced conveyance belts 9 and forcibly conveyed to the paper outlet 2.

The forced conveyance belt should be a flat belt or a round belt, and should be installed at a position that lightly sandwiches the paper.

According to this method, the paper guide 15°15' is caused by static electricity.
It is possible to feed the paper to the paper outlet 2 without sticking to the paper (Fig. 3).

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to change the paper feeding direction to the required angle without damaging the paper simply by inserting the paper through the insertion slot, and moreover, it is possible to feed the paper accurately and at high speed. can.
