Description

DETAILED DESCRIPTION OF THE INVENTION Processing of individual sheet materials   The present application describes a method and system for handling individual sheet materials (A PROCESS AND SYS TEM FOR HANDLING DISCRETE SHEETS OF MATERIAL), June 1, 1995 A continuation-in-part of U.S. Patent Application Serial No. 08 / 489,356, filed on February 2. BACKGROUND AND SUMMARY OF THE INVENTION   The present invention generally relates to systems used in handling individual sheet materials. And more particularly, to a method and apparatus for rapid processing of individual sheet materials. I do.   Many processing systems known today consist of a continuous wafer of uncut material. And sends it to the processing zone where it performs some type of processing. An example For example, in the packaging industry, a continuous web of material is sent into a printing system. And then cut into individual packaging units to be wrapped in the prescribed packaging shape You. The printing process for newspapers is another example, where the material being fed continuously (ie, paper ) Enters the printing process and is subsequently cut into individual parts.   Of course, printing is not the only process built into such systems; , Is not the only type of material that is continuously fed into such systems. Normal In a continuous feed system in the industry, many processes use many different materials Has been implemented for   Known continuous material web systems have certain disadvantages in some applications. ing. For example, in many known web systems, points in the system Average speed of material movement Even at high speeds, material moves at many other points in the system.   In some processing applications, the speed of the material at one point in the system Degree without lowering the material speed at many other points in the system. Can be beneficial. The invention relates to a stack of disjointed sheet materials. A method and system for providing the same to predetermined processing steps. Sheet source A stack of sheet material that has been cut in advance, or Web system theta with discrete sheets cut from a continuous web Output section (a web system sheeter output). overlapping The sheet material reduces the speed of the material through the processing zone. Surface area of adjacent sheets The greater the overlap of regions, the lower the speed. For example, 50% weight In the case of contact, it is half the speed of the conventional web system, but the same overall speed as the web Cards (separated sheets) into the processing zone at a typical throughput rate Can be. For high percentage stacks, the feed rate in the entire system This is not tolerated, but has the advantage that the card moves slowly during processing. This low speed is beneficial in that many operations are performed well at low tracking speeds. is there. For example, paper passing through an ink jet printer Cannot be printed properly when passing through Labeling machines (labelers) Low speed, but not at full traditional web system speed. No.   Electrostatic treatment, adhesion, ink jet, laser to be applied to the stacked sheets It should be noted that processes such as belling are within the scope of the present invention.   The above and other advantages are provided by the following detailed description of the invention, the drawings, and the claims. It will be clear from the range. BRIEF DESCRIPTION OF THE FIGURES   Various features and advantages of the present invention will be readily apparent from the following description taken in conjunction with the accompanying drawings. Can be understood. In the drawings, the same reference numerals refer to the same structural elements. Is attached.   FIG. 1 is a side view of one preferred embodiment of the present invention.   FIG. 2 is a top view of a stack of material cards of the present invention.   FIG. 3 is a top view of another embodiment of the present invention. Detailed Description of the Preferred Embodiment   Referring to FIG. 1, one embodiment 10 of the present invention is shown. This special implementation In the embodiment, a stacking of a shingling transfer / conveyor 14 and a sheet is performed. It has an overlapping body 12. The conveyor 14 stacks the stacked sheets 16 downward. It is transported to the elevator 18. The stacked sheets 16 are conveyed (with constant movement). During the operation, the processing 20 for the sheet 16 is performed. Preferably, this treatment 20 is non-contact or irregular such as laser, labeling, printing, coating, gluing etc. Contact processing. The sheet source of the sheet 12 is a web sheeter. That is, a web-like material rather than a stack of sheets as shown in FIG. Note that these are cut into individual sheets prior to processing It should be.   FIG. 2 is a view of a part of the stacked sheet 16 as viewed from above. Individual card sand That is, the surface of the sheet may be partially exposed during stacking. All systems When passing through the predetermined processing unit , Detecting the leading end portion 26 of each card and triggering the start of processing on the card. Sensors can be used to pull. Each card has the desired exposed area In order to perform the process 20, only the necessary area needs to be exposed.   FIG. 3 shows another embodiment of the present invention. In this embodiment, the transfer is performed at a substantially higher speed. The moving continuous web of material is cut into individual sheets 32. Then individual Sheet 32 is forcibly transported onto conveyor 34. The sheet is 90 degrees to the right hand side, 90 degrees to the left hand side to the web, or lined up with the web Can be placed on the conveyor in a predetermined orientation, such as straight on the conveyor, etc. it can. Preferably, sheet 32 partially overlaps adjacent sheets on conveyor 34 Overlap. Conveyor speed is lower than web speed.   The exposed portion of each sheet is conveyed through the processing device 36 and processed for the exposed portion. As will be appreciated, the sheet 32 moves continuously through the system. Processed sheet An accumulator 38 or receiving device may be provided near the conveyor to collect it can.   By overlapping adjacent sheets, the output speed of the entire system does not need to be changed And systems that include continuous web material across all of the processing steps. In comparison, individual sheets can be moved at lower speeds in processing steps You.   Although the invention has been described in terms of several embodiments, it is to be understood that without departing from the scope of the appended claims. It should be understood that various changes and modifications can be made to the present invention. You.
