Definitions
- the present invention relates to an automatic paper feeder that automatically feeds paper to an apparatus such as a printer or a scanner, and to an automatic paper feeder that realizes feeding of paper one sheet at a time. is there.
- the pressure pad 53 is applied to the surface of the pick roller 50 so that the separation pad 51 is brought into contact with the pick roller 50 so that a sufficient frictional force acts between the pick roller 50 and the separation pad 51.
- a pad pressurizing means 52 for applying a pressure for bringing the separation pad 51 into contact is provided.
- the separation pad 51 inevitably has a narrow area in contact with the pick roller 50, and the separation pad 51 cannot completely separate a plurality of overlapped sheets, and double feeding may occur. .
- the shape of the pad pressing means 52 for applying pressure to the separation pad 51 is an inverted U shape, so that the separation pad 51 is added to the surface of the pick roller 50 at two locations. It has been devised that the sheet can be pressed and the sheets can be more reliably separated one by one (for example, see Patent Document 1).
- Patent Document 1 JP-A-8-91609
- the pick roller is equipped with a separation pad to pick up the paper loaded on the stat force one by one, and the paper is separated by the friction force between the pick roller and the separation pad. If the pad pressurizing means that presses the pressure is configured to press in one place, it is difficult to optimize the pressure applied to the separation pad, and transport errors such as double feeding have occurred.
- the pad pressurizing means has an inverted U-shape, and the separation pad is pressed against the pick roller at two positions in the front and back, thereby making it possible to carry a transport error such as double feeding. Does not occur! However, depending on the type of paper, the pressure applied to the two places before and after the separation pad is not uniform, and a transport error may occur.
- An object of the present invention is to provide an automatic paper feeding device that is used in a printer, a scanner, or the like, and that automatically feeds paper to the device. It is another object of the present invention to provide an automatic paper feeder that conveys paper.
- the present invention takes the following means.
- the pad pressurizing means that presses the separation pad against the pick roller has an inverted U-shape, and further pressurizes the pad pressurization means so that the separation pad is pressed against the pick roller. Configure the panel to be provided in the center of the pad pressurizing means! /
- the pad pressing means is configured to have a rotation fulcrum so that the pad pressing means can be rotated back and forth with respect to the rotation direction of the pick roller around the joint between the pad pressing means and the pressure panel. .
- the pad pressurizing means when feeding thick paper or the like, is centered on a predetermined position at a rotation fulcrum that is a connecting portion of the pressurizing panel so that a large load is not applied to the entire pad pressurizing means It is also possible to provide a rotating arm so that the entire pressurizing means including can be rotated.
- the position where the pressure panel is coupled to the pad pressure means may be moved back and forth instead of the rotation fulcrum at the center of the pad pressure means.
- the friction force generated between the pick roller and the separation pad can be reliably separated one by one by generating the optimum friction force regardless of the type of paper.
- the paper can be fed into the device.
- FIG. 1 is an overall configuration diagram of the present invention.
- FIG. 2 is an explanatory view when a rotating arm is provided.
- FIG. 3 is an explanatory diagram when a pressure panel is provided in front.
- FIG. 4 is an explanatory diagram when a pressure panel is provided on the rear side.
- FIG. 5 is an explanatory view of a conventional means for pressurizing a separation pad.
- FIG. 6 is an explanatory diagram when a conventional inverted U-shaped pad pressurizing means is used.
- the present invention takes the following embodiments.
- a pressure panel and a pad pressure means are provided so that the separation pad comes into contact with the pick roller at an appropriate pressure.
- the configuration of the pad pressing means is an inverted U-shape, and the separation pad is configured to be pressed against the pick roller at two positions in the front and rear. This makes it possible to separate a plurality of sheets one by one more stably than when the separation pad is pressed against the pick roller at one place.
- a rotation fulcrum is provided at the center of the pad pressurizing means, and the pressure by the press panel is applied thereto.
- the pressure applied to the separation pad can be made uniform at the two front and rear locations, and stable paper separation processing can be performed.
- a rotation arm may be provided at the rotation fulcrum of the pad pressurizing unit so that the pad pressurizing unit can rotate around a predetermined position.
- the picked paper is thick paper and tries to push up the separation pad with force and force, so that excessive force is not applied to the pad pressurizing means, and appropriate force is applied to the separation pad. I ’m going to do something.
- the position where the pressure is applied to the pad pressurizing unit by the pressurizing panel may be freely changed before and after the center of the pad pressurizing unit.
- the pressure can be applied to the front side to increase the pressure, so that double feeding or the like can occur. If it is thick, the pressure on the rear side can be increased so that double feeds can occur.
- FIG. 1 shows an embodiment of the present invention.
- a sheet 6 is picked by a pick roller 1 and conveyed between the pick roller 1 and the separation pad 2 and is configured to pick only one of a plurality of sheets by a frictional force.
- the pad pressing means 3 for applying pressure to the separation pad 2 is provided so that the frictional force between the pick roller 1 and the separation pad 2 becomes a force suitable for the separation process of the paper.
- the pad pressing means 3 applies a pressing force so that the separation pad 2 comes into contact with the surface of the pick roller 1. However, when pressing is performed at one point, it is difficult to obtain an appropriate frictional force. Yes, Pick mistakes such as double feeding are likely to occur.
- the configuration of the pad pressurizing means 3 is an inverted U-shape, so that the separation pad 2 is pressed at two places in the front and rear.
- the frictional force can be measured in a wide range, so that it is possible to apply pressure more easily than the case of applying pressure at a single point so as to obtain an appropriate frictional force.
- the pad pressurizing means 3 can be rotated back and forth with respect to the rotation direction of the pick roller 1 at the joint with the pressurizing panel 4 that applies pressure to the pad pressurizing means 3.
- Rotating fulcrum 5 is provided so that the pressure applied at the two front and rear can be made uniform.
- the rotation arm 7 having a predetermined position as the center of rotation is used as a rotation fulcrum so that an excessive force is not applied to the entire pressurizing unit depending on the thickness of the fed paper. It may be set to 5.
- the node pressurizing unit 3 makes the separation pad. A larger force can be applied to the front side of the two places applied to 2, and even when the paper is thin and multi-feeding is likely to occur, the paper can be reliably separated.
- the position of the pressure panel 4 for applying pressure to the pad pressure means 3 is moved rearward from the center so that the pad pressure means 3 separates it. It is possible to apply a greater force to the rear side of the two places applied to the pad 2, and even when the paper is thick and jamming occurs, it is possible to ensure that the paper is separated.
