Abstract

Clearance of copy sheet jams in traveling distributor or moving-vane-type collators is facilitated by moving the distributor/vane either automatically or in response to a manually operated switch so that the distributor/vane is displaced from collator bin openings wherein access is restricted. The improvement is particularly applicable to IBM Series III copier/duplicator-type equipment. Details of a typical traveling distributor and its relationship to the collator bins are shown in the IBM Technical Disclosure Bulletin 21, 4776-4779 (May 1979). In collators of the traveling distributor or moving vane type, it is sometimes difficult to remove the sheets from the jam area especially when a copy sheet jams near the first few bins.

Collator Jam Clearance and Recovery Process and Apparatus

Clearance of copy sheet jams in traveling distributor or moving-vane-type collators is facilitated by moving the distributor/vane either automatically or in response to a manually operated switch so that the distributor/vane is displaced from collator bin openings wherein access is restricted. The improvement is particularly applicable to IBM Series III copier/duplicator-type equipment. Details of a typical traveling distributor and its relationship to the collator bins are shown in the IBM Technical Disclosure Bulletin 21, 4776-4779 (May 1979). In collators of the traveling distributor or moving vane type, it is sometimes difficult to remove the sheets from the jam area especially when a copy sheet jams near the first few bins. Forcing the distributing mechanism downwardly away from the top bins can cause misalignment between the distributor and bin openings as well as damage to collator parts. Furthermore, subsequent operation of the collator following jam clearance and manual movement of the distributor/vane typically results in inappropriate resumption of sheet distribution starting at the final bin location to which the vane/distributor was moved. The Fig. 1 configuration allows the operator to lower the distributor/vane from the bin opening locations when a paper jam occurs to enhance paper removal by improving accessibility to the jam area. Double-pole switch 12 in collator 10 has a single pushbutton 15. Operation of pushbutton 15 by the operator causes index solenoid 18 to actuate by coupling it to ground lead 21. In addition, a signal is produced over line 22 to microprocessor control 25 in copier 11 to cause the collator motor (not shown) to operate. Switch 15 is preferably accessible by the operator with covers closed so that the operator can lower the distributor/vane to a lower position, thereby permitting easy access to paper jams, especially at upper bin locations in collator
10. Microprocessor control 25 is programmed to only allow collator motor operation when (1) the collator door is closed and (2) a Check Paper Path or error condition in collator 10 is detected. Other locations of switch 12 are acceptable, such as behind the collator front door at approximately the top bin location but accessible to the user. Automatic repositioning of the distributor/vane without use of a manually operated switch is possible, and Fig. 2 illustrates a general flowchart of one example of such an automatic process employing a copier/collator controlling microprocessor. The process illustrated in Fig. 2 assumes that facilitated jam clearance access is...
