Stacker

Abstract: An apparatus for sorting sheets is disclosed, which comprises a feeder for setting a mixture of different kinds of sheets, the set sheets being fed one by one for sorting, a judging circuit for judging the kind of sheets being transported through the body after having been fed from the feeder, and a stacking section for stacking sorted bills according to the results of the judging circuit. The stacking section includes an upper stacker, a lower stacker, and a reject stacker, sheets of a specified kind being stacked in the upper stacker, sheets incapable of being judged being stacked in the reject stacker, and the other sheets being stacked in the lower stacker.

Abstract: The study of Automated Storage/Retrieval Systems (AS/RS) in warehouses has developed along two main lines: One seeks to minimize total cost of an AS/RS, while the other explores the dynamic behavior of such a system. This study addressing the two issues simultaneously, obtains design parameters for a system that complies with desired levels of performance. To this end, a heuristic recursive optimization/simulation procedure is developed. It is also assumed that the number of stacker cranes (an important cost component of AS/RS) can be less than or equal to the number of aisles. The proposed procedure was applied to several situations, and converged within a few iterations.

Abstract: This invention pertains to the type of apparatus for handling sheets shown in U.S. Pat. No. 3,658,322 and particularly to the take-off conveyor on such apparatus on which the direction of the sheets issued from the sheet making machine is changed toward a stacker. The improvements pertain to the accurate adjustment of the back-up means on the take-off conveyor to correspond to the length of the sheets delivered from the sheet making machine thereby to allow accurate stacking of the bundles of sheets on the take-off conveyor; the adjustability is accomplished through a suitable selector dial on circuit control device which is calibrated for the length of the sheets and which when set to the particular length then through an electric circuit and driving mechanism moves the back-up abutments to that selected measurement accurately and automatically; another improvement is the adjustability of the snubber device at the discharge end of the take-off conveyor for adjustment to the thickness of the bundles of sheets; a further improvement includes adjustable snubbers on the layboy at the intake of the stacker device for adjustment to the width of the sheets for the proper transmittal of the sheets to the stacker conveyor.

Abstract: In this manuscript we present a focus stacking system, composed of commercial photographic equipment. The system is inexpensive compared to high-end commercial focus stacking solutions. We tested this system and compared the results with several different software packages (CombineZP, Auto-Montage, Helicon Focus and Zerene Stacker). We tested our final stacked picture with a picture obtained from two high-end focus stacking solutions: a Leica MZ16A with DFC500 and a Leica Z6APO with DFC290. Zerene Stacker and Helicon Focus both provided satisfactory results. However, Zerene Stacker gives the user more possibilities in terms of control of the software, batch processing and retouching. The outcome of the test on high-end solutions demonstrates that our approach performs better in several ways. The resolution of the tested extended focus pictures is much higher than those from the Leica systems. The flash lighting inside the Ikea closet creates an evenly illuminated picture, without struggling with filters, diffusers, etc. The largest benefit is the price of the set-up which is approximately € 3,000, which is 8 and 10 times less than the LeicaZ6APO and LeicaMZ16A set-up respectively. Overall, this enables institutions to purchase multiple solutions or to start digitising the type collection on a large scale even with a small budget.
