Abstract

A sheet material distributing apparatus includes a plurality of bins for accommodating sheet materials, a first sheet material gripping and conveying device displaceable to be opposed to a sheet material inlet of each of the bins, and a second sheet material gripping and conveying device displaceable to receive a sheet material from a sheet material discharging device and for transferring the sheet material to the first sheet material gripping and conveying device.

Claims

1. A sheet material distributing apparatus, comprising:

a plurality of bins for accommodating sheet materials, each of said bins having a sheet material inlet;

a first sheet material gripping and conveying means movable to be opposed to the sheet material inlet of each of said bins;

second sheet material gripping and conveying means linearly movable to receive one of the sheet materials from a sheet material discharging device to transfer the sheet material to said first sheet material gripping and conveying means.

2. An apparatus according to claim 1, further comprising a pressure releasing mechanism for removing a sheet material gripping force of said second sheet material gripping and conveying means before it returns to a position for receiving the sheet material from the sheet material discharging device.

3. An apparatus according to claim 1, further comprising means for controlling a conveyed speed V_R of said second sheet material gripping and conveying means to be V1+V2 during a period when said second sheet material gripping and conveying means returns to a position for receiving the sheet material from the sheet material discharging device, where V1 is a sheet material conveying speed of said first sheet material gripping and conveying means, and V2 is a returning speed of said second sheet material gripping and conveying means.

4. An apparatus according to claim 1, further comprising control means for controlling said first sheet material gripping and conveying means to move stepwisely in correspondence with said bins and in correspondence with a position where said first sheet material gripping and conveying means receives the sheet material from said second sheet material gripping and conveying means.

5. An apparatus according to claim 1, further comprising control means for controlling movement of said first sheet material gripping and conveying means so that a position where said first sheet material gripping and conveying means receives the sheet material from said second sheet material gripping and conveying means is common to at least two bins.

6. An apparatus according to claim 1, further comprising bin position detecting means provided in said first sheet material gripping and conveying means, and detecting means provided in said second sheet material gripping and conveying means for detecting a position of said first sheet material gripping and conveying means.

7. An apparatus according to claim 4, further comprising detecting means for detecting that the sheet material is gripped by said first sheet material gripping and conveying means, and control means for controlling said second sheet material gripping and conveying means to return it to a position for receiving the sheet material, when said detecting means detect the gripping of the sheet material by said first sheet material gripping and conveying means.

8. A sheet material distributing apparatus, comprising:

a plurality of movable bins for accommodating sheet materials, each of said bins having a sheet material inlet;

a first sheet material gripping and conveying means opposed to the sheet material inlet of each of said bins;

second sheet material gripping and conveying means linearly movable to receive one of the sheet materials from a sheet material discharging device to transfer the sheet material to said first sheet material gripping and conveying means.

9. An apparatus according to claim 8, further comprising a pressure releasing mechanism for removing a sheet material gripping force of said second sheet material gripping and conveying means when it returns to a position for receiving the sheet material from the sheet material discharging device.

10. An apparatus according to claim 8, further comprising means for controlling a conveying speed V_R of said second sheet material gripping and conveying means to be V1+V2 during a period when said second sheet material gripping and conveying means returns to a position for receiving the sheet material discharging device, when V1 is a sheet material conveying speed of said first sheet material gripping and conveying speed of said first sheet material gripping and conveying means, and V2 is a returning speed of said second sheet material gripping and conveying means.

11. An apparatus according to claim 8, further comprising bin position detecting means provided in said first sheet material gripping and conveying means, and detecting means provided in said second sheet material gripping and conveying means for detecting a position of said first sheet material gripping and conveying means.

12. An apparatus according to claim 8, further comprising detecting means for detecting that the sheet material is gripped by said first sheet material gripping and conveying means, and control means for controlling said second sheet material gripping and conveying means to return it to a position for receiving the sheet material, when said detecting means detect the gripping of the sheet material by said first sheet material gripping and conveying means.

13. An image forming apparatus, comprising:

sheet discharging means for discharging sheet materials on which images have been formed;

a plurality of bins, arranged in a direction, for accommodating the sheet materials each of said bins having a sheet material inlet;

a first sheet material gripping and conveying means movable in the direction to be opposed to the sheet material inlet of each of said bins;

second sheet material gripping and conveying means movable in the direction to receive one of the sheet materials from said sheet discharging means to transfer the sheet material to said first sheet material gripping and conveying means.

14. An image forming apparatus, comprising:

sheet discharging means for discharging sheet materials on which images have been formed;

a plurality of movable bins arranged in a direction, for accommodating the sheet materials each of said bins having a sheet material itself;

first sheet material gripping and conveying means which is opposed to the sheet material inlet of each of said bins;

second sheet material gripping and conveying means movable in the direction to receive one of the sheet materials from said sheet discharging means to transfer the sheet martial to said first sheet material gripping and conveying means.
