Field of the Invention The present invention relates to a sheet feeding table for conveying sheets at a predetermined timing to a sheet processing machine, which are arranged at intervals on a table surface. One or more suction belts for transporting the sheets, which extend in the transport direction, are drivably guided so as to move in the transport direction, and the suction belts are formed endlessly and have a receiving area and The feed belt surrounds the feed table via a diverting roller located in the transfer area, and further comprises a suction belt having a plurality of consistently extending suction openings distributed over its entire length; Of the type in which the lower side is loaded with a negative pressure.

も云える。2. Description of the Related Art In a known paper feed table of this type, if a part of a suction opening of a suction belt is not blocked by a sheet to be conveyed during operation of the paper feed table,
That is, if not closed, a negative pressure loss may occur in the case of a negative pressure load for various reasons. This is the case, for example, when the width of the conveyed sheets is smaller than the distance between the outer suction belts. This applies both to the transport of the sheets in a deviating double flow and to the transport of individual sheets.
【０００３】さらに、個別枚葉紙搬送では、各枚葉紙の

開いている範囲において、負圧損失が生じる。Further, in the individual sheet transport, a negative pressure loss occurs in a range between the individual sheets, that is, in a range where the suction opening of the suction belt is open without being blocked.

ることである。An object of the present invention is to improve a sheet supply table of the type mentioned at the outset, so that the sheets are applied to the suction belt at every point of the sheet supply table with an optimum holding force in each case. An object of the present invention is to provide a sheet feeding table to be held.

制御可能であるようにした。SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the configuration of the present invention, one or more suction belts are provided.
Numerous load ranges which are loaded with positive and / or negative pressure in the conveying direction are arranged in such a way that the positive and / or negative pressure loads in these load ranges can be controlled independently of one another. I did it.
【０００９】[0009]
【発明の効果】この構成により、枚葉紙を吸引ベルトに
保持する保持力を、給紙テーブルのあらゆる箇所で最適
な値に調節することが可能になる。この場合、負圧負荷

い枚葉紙の変位を必要とするが、それに対して、直後に
続く枚葉紙はまだ吸引ベルトに変位不能に保持されなけ
ればらない。According to this configuration, it is possible to adjust the holding force for holding the sheet to the suction belt to an optimum value at every position of the sheet feeding table. In this case, for the purpose of suddenly achieving a low holding force after a load range in which a high negative pressure load is applied, after a range of high required holding force in which a negative pressure load is performed, a low negative pressure load or even a positive pressure is used. The load range in which the load is performed may continue. This is advantageous, for example, in the end area of the sheet feeding table where the lateral position adjustment is to be performed. In other words, this lateral position adjustment requires the displacement of the sheet to be adjusted, whereas the immediately succeeding sheet must still be held in a non-displaceable manner on the suction belt.
【００１０】その都度処理される枚葉紙の枚葉紙品質に

な剛性を有する枚葉紙とは異なる保持力を必要とする。
また、大きな空気透過性の枚葉紙においても、小さな通
気性の枚葉紙とは異なる負圧レベルが好都合となる。It is also possible to vary the positive pressure load and / or the negative pressure load in relation to the sheet quality of the sheet to be processed in each case. That is, lighter sheets require a different holding force than sheets having greater rigidity.
Also, for large air-permeable sheets, a different negative pressure level than for small air-permeable sheets is advantageous.
【００１１】最初の枚葉紙と、最後の枚葉紙における不
本意な負圧損失も、本発明の構成によって回避される。
なぜならば、アクティブな負荷範囲と環境大気との短絡
が行われないからである。[0011] Inadvertent negative pressure losses in the first and last sheets are also avoided by the design according to the invention.
This is because no short circuit occurs between the active load range and the ambient air.
【００１２】負荷範囲の正圧負荷および／または負圧負

ては吸引ベルト上の枚葉紙の保持力の変化も回避され
る。[0012] The positive pressure load and / or the negative pressure load of the load range may be controllable in relation to the degree of shielding of the load range by the conveyed sheets. As a result, a negative pressure loss or a positive pressure loss due to a short circuit with the ambient atmosphere is avoided, and a change in the holding force of the sheet on the suction belt is also avoided.
【００１３】さらに、正圧または負圧の形成のために調
達されるべきエネルギーは、必要最小限に減らされる。Furthermore, the energy to be procured for the formation of a positive or negative pressure is reduced to a minimum.

遮蔽されている負荷範囲のみが正圧または負圧で負荷さ
れる。このことは、たとえば枚葉紙流の始端と終端でも
有利である。When the load range shielded by the sheet and the load range unshielded by the sheet transport movement change, the load in the load range can be permanently changed. Thus, only the load range that is always shielded by the sheet is loaded with positive or negative pressure. This is advantageous, for example, at the beginning and end of the sheet flow.
【００１５】負荷範囲は、種々異なる圧力レベルの正圧
および／または負圧で負荷されるように制御可能であ

保持するためには、負荷範囲が、搬送したい枚葉紙のず
れ重ね流のずれ重ね間隔にほぼ相応する間隔を置いて配
置されていてよい。In order to hold each sheet on the suction belt with an optimum holding force at every point of the conveying path when the sheet is conveyed in a shifted overlapped flow, the load range is limited to the shifted overlapped flow of the sheet to be conveyed. May be arranged at intervals substantially corresponding to the offset overlap intervals.
【００１７】種々異なるずれ重ね間隔のずれ重ね流で枚
葉紙を搬送しようとする場合、負荷範囲が、搬送したい
ずれ重ね流れのできるだけ小さいずれ重ね間隔にほぼ相

利である。In the case of a feed table for conveying individual sheets, the load ranges are preferably arranged at a distance from one another that corresponds to the sheet distance of the individual sheet flow to be conveyed. .
【００１９】もちろん、本発明の構成により、枚葉紙を
ずれ重ね流でも、個別枚葉紙流でも搬送することが基本
的に可能である。Of course, the configuration according to the invention makes it basically possible to convey the sheets both in a displaced overlapping flow and in an individual sheet flow.

圧が迅速に形成可能もしくは解消可能となる。In order to be able to control the individual load ranges accurately and quickly alternately, a positive pressure generator and / or a negative pressure generator may be assigned to each load range. This also keeps the volume to be placed under negative or positive pressure small, so that a positive or negative pressure can be quickly established or eliminated.

Alternatively, a separately controllable ventilator for the negative pressure load may be provided, or each load range may be connected to a positive pressure source and / or a negative pressure source via a separately controllable valve. .
