A paper separating and conveying apparatus and a paper separating and conveying method according to an embodiment of the present invention will be described with reference to the drawings.
1 to 6, P is a paper separating / conveying device, and the paper separating / conveying device P is a predetermined number of sheets (for example, about 40 sheets per ream) located above the sheet 2 stacked on the table 1. The separated paper 21 is sent from the table 1 to another process (for example, a packaging process for packaging the paper separated into a predetermined number).

Reference numeral 3 denotes a feeding member that feeds out a predetermined number of sheets (for example, about 40 sheets per ream) from the sheet 1 positioned above the sheet 2 stacked on the table 1 from the table 1. Although not shown, the feeding member 3 is provided with a predetermined number of markers on the side surface of the laminated paper 2 or a ream marker tape (not shown) is sandwiched between the predetermined numbers. (Not shown) or a ream marker tape (not shown) is detected, and the tongue portion 31 of the delivery member 3 enters the laminated paper 2 and the tongue portion 31 enters the laminated paper 2. In the entered state, the sheet 1 is lifted by the lifter 5 so that the lower surface of the paper to be separated is flush with the conveying surface of the conveying unit 4 (see FIGS. 1 and 3).
After the lifter 5 is lifted, the feeding member 3 moves forward toward the transport unit 4 and feeds the paper separated from the paper positioned above the paper 2 stacked on the table 3 into a predetermined number from the table 3 ( Delivery process).

Reference numeral 6 denotes a holding transition member that holds and transfers the paper 21 separated by a predetermined number that is fed by the feeding member 3. The holding transition member 6 holds and transports the paper 21 that has been separated by a predetermined number that is fed in the feeding process. For example, when the paper 21 separated into a predetermined number is positioned between two opposing members, one member descends and hits the upper surface of the paper 21 separated into the predetermined number. The paper 21 is held in contact with each other, the opposing members move in the horizontal direction, and after moving a predetermined distance, one member in contact with the upper surface of the paper 21 rises to release the holding of the paper 21. is there.
4 is a transport unit that transports the paper 21 separated and transferred by the holding transition member 6 so as to be separated from the paper 2 stacked on the table 1. The transport unit 4 is described later. The holding transfer member 6 is positioned on the transport unit 4 by, for example, a belt conveyor, which transports the paper applied with the electric field in the electric field step (electric field unit 7).

7 is an electric field portion that is located above the paper 21 separated into a predetermined number and performs an electric field step of applying an electric field from above the paper 21 separated into the predetermined number to be sent out in the middle of the transition process. It has one electrode part 71 which applies an electric field, and the other electrode part 72 provided in the position which contacts this one electrode part 71 and contact | abuts the lower surface of the paper 21 isolate | separated into the predetermined number.
One electrode 71 for applying an electric field from above the predetermined number of papers 21 to be fed is above the predetermined number of the stacked papers 2 and is laminated with the transport unit 4 in plan view as shown in FIG. Between the printed paper 2.
When a voltage is applied between one electrode portion 71 and the other electrode portion 72, an electric field is generated between one electrode portion 71 and the other electrode portion 72, and a predetermined number of sheets facing one electrode portion 71 The paper 21 on the upper surface of the paper 21 separated into (for example, about 40 sheets per ream) is, for example, plus, and the paper 21 separated into a predetermined number (for example, about 40 sheets per ream) that contacts the other electrode part 72. For example, the paper on the lower surface of the paper 21 becomes negative, and the back surface of the upper surface of the paper 21 separated into a predetermined number (for example, about 40 sheets per ream) facing the one electrode portion 51 is negative and faces the back surface. The paper side is positive. That is, the papers on the opposing surfaces that come into contact with each other are in close contact with each other with different polarities. The paper 21 separated into a predetermined number by this polarity is brought into close contact, and can be prevented from shifting.

    Accordingly, the tongue 31 of the feeding member 3 enters the laminated paper 2 and is lifted by the lifter 5 so that the lower surface of the paper on which the table 1 is to be separated is flush with the conveying surface of the conveying unit 4. Thereafter, the feeding member 3 moves forward toward the transport unit 4 and a predetermined number of stacked sheets fed by the feeding member 3 [paper 21 separated into a predetermined number of sheets (for example, about 40 sheets per one ream)]. It is held by the holding transfer member 6 and transferred to the transport unit 4. At that time, an electric field is applied from above the fed paper by the electric field unit 7, and the paper on the opposite surface where the paper 21 separated into a predetermined number of sheets (for example, about 40 sheets per ream) contacted is electrically Thus, they are adhered to each other with different polarities, and the transport unit 4 is transported to a packaging process (not shown) while preventing misalignment of the stacked paper.

    In the above-described embodiment, the paper separated from the paper 1 positioned above the paper 2 stacked on the table 1 by the feeding member 3 into a predetermined number (for example, about 40 sheets per ream) from the table 1. Although the feeding is performed, depending on the case, it may be performed artificially regardless of the feeding member 3. In such a case, the paper separating / conveying method includes a transition process in which a predetermined number of sheets 21 fed from a sheet positioned above the sheet 2 stacked on the table 1 are held and transferred to the conveying unit 4, and this transition In the middle of the process, there is provided an electric field step of applying an electric field from above the paper 21 separated into a predetermined number of sheets to be sent out, and a conveying step of conveying the paper separated into the predetermined number of electric fields applied in this electric field step. It will be.
