Title: Improvements relating to devices for separating sheets one by one from a stack of sheets
IPC: B65C9/14
Filed: 1969-11-18
Abstract: 1,234,910. Feeding sheets. SCHWEIZERISCHE INDUSTRIE-GES. 18 Nov., 1969 [19 Nov., 1968], No. 56256/69. Heading B8R. Apparatus for separating flexible sheets such as labels from a stack 4 having the sheets standing on edge, comprises a suction head 11 rotatable about an axis which is displaceable parallel to itself, the head having a curved surface which rolls along the surface of the foremost sheet 5 to move the upper edge of that sheet by suction away from the stack, and a pivotallymounted blower and stack-supporting wedge 27 which is inserted between the upper edge of sheet 5 and the stack to cause complete detachment of the sheet 5 from the stack and from a retaining abutment 2a. The detached sheet is ejected by conveyer rollers 33, 34. From an initial position, Fig. 1, the axis of the suction head 11 first is moved from A to B, such movement causing, through toothed gearing, the head 11 to roll downwardly over the top part of the sheet 5 to move that part away from the pile. An arm 26 is now actuated to move the wedge member 27 into the gap thus formed, to support the stack. At the same time, a pressure plate 32a normally bearing against the front of the stack is moved away from the stack. An air blast of short duration is now caused to issue from the bore 28 of the member 27 to complete the release of the sheet 5 and to move its lower edge over the abutment 2a. Finally the head 11 is rotated about the axis B by the toothed gearing back to its initial rotary position, thus moving the sheet 5 downwardly into the bite of the rollers 33, 34. The parts are then returned to their initial position, Fig. 1. The stack 4 is supported in a feed channel 1, Fig. 3, having a base comprising a fixed part 2 and a reciprocating part 3. A wall 10 pressing against the back of the stack is mounted on rollers 9.

Abstract: 1,215,460. Removing and confining dust &c. in industrial processes. L. M. CHRISTIANSON. 12 Dec., 1967, No. 56343/67. Heading F4X. [Also in Division B1] In apparatus for separating and collecting dust from a building 9, entrained dust laden air is induced through a conduit 28 by a main blower 29 and discharged via conduit 30 and ducts 31- (34, Fig. 2) into separator units 10-13 respectively wherein the dust is collected, the dust free air being returned to the building 9 through air permeable separator walls 16 made, e.g. of canvas. Each separator, e.g. 10, is provided with a shoot 15 which communicates with a closed housing 50 via a gate valve 54 actuated by an air cylinder 58; each respective duct, e.g. 31 is also provided with a similarly actuated gate valve 35. In operation entrained dust is collected in three of the separators, e.g. 11, 12, 13, whilst the remaining separator, e.g. 10 is isolated from the blower 29 by closing the top gate valve 35, and the lower gate valve 54 is then opened to allow dust to be emptied out on to a conveyer belt 65. A small capacity blower 85 creates an induced air flow in the housing 50. Alternatively a damper 89 in conduit 88 is opened to communicate the housing 50 with the intake of the main blower 29. A secondary separator indicated at 72 comprises a rotatably mounted perforate drum 73 which bears against and is driven by the belt 65. The fine dust, some of which is air-borne, passes through the perforate drum 73 and into a duct 76 communicating with one end of the drum 73, and then through the blower 85 which returns it via conduit 86 to one of the separators 11, 12 or 13. The remaining dust passes via a shoot 52 into a collecting container 53. The separators are each emptied in this manner in rotation. A rotary beater 96 together with a brush 99 clean the periphery of drum 73.

Articles, e.g. chocolates, of different sorts are fed in respective columns on a conveyer to accumulate against end stops 25, the conveyer is stopped, the conveyer and end stops 25 are moved relatively to one another so as to eliminate the contact pressure on the foremost articles, and grippers (not shown) place the foremost articles in predetermined arrangement in cartons. As described, the chocolates are fed on a continuously moving main conveyer belt 1 in columns defined by walls 9 and delivered to an end conveyer belt 31. The columns on this conveyer are defined by walls 9a pivoted about axes 19 and moved periodically by a rod 21 in the directions 23 to align the articles by lateral impacts. Normally, the end conveyer 31 is driven more rapidly than conveyer 1 so that the chocolates close up as they accumulate against stops 25. Conveyer 31 is now stopped, and grippers (not shown) hold the chocolates which abut the end stops 25. The end stops are pivotally moved in the direction 37 and/or the end conveyer 31 is moved for a short distance opposite to the direction of feed of the chocolates, thereby removing the contact pressure on the chocolates held in the grippers. The grippers then place the chocolates into a carton 27. The grippers 25 need not lie on a straight line and are individually movable in the longitudinal directions 35 to lie in any desired fixed arrangement relative to each other to place the articles into the carton in such arrangement.

Abstract: 1381733 Cash dispensing GLORY KOGYO KK 29 Dec 1971 [28 Dec 1970 29 Dec 1970] 60493/71 Heading G4X In electronically-controlled money dispensing apparatus, signals corresponding to the digits of a total amount of money to be dispensed are produced, at least one signal is analysed and if the corresponding digit lies within a predetermined range of values, money corresponding to this digit place is dispensed in a first denomination of money, whereas if the corresponding digit lies outside this range money is dispensed in second denomination, either alone or together with the first. For each denomination of the number of currency units to be dispensed, there is provided a tube 1, for storing the digit of the respective denomination, for visually displaying this digit and for giving a low level output signal on a terminal T corresponding to the digit, high level outputs appearing on all other terminals T. For example, the tube 1 shown may denote the number of thousands of yens to be dispensed. Five thousand and one thousand yen notes are available and it is required to dispense the minimum number of notes consistent with the number of thousand yens required. If tube 1 holds digit " 0 ", To is low and output relay 7a of circuit 2a is de-energized. Relay 7b of circuit 2b is energized because of the high signals on T 5 -T 9 . If tube 1 hold any of digits " 5-9 ", 7b is de-energized and 7a is energized. If tube 1 holds any of digits " 1-4 ", relays 7a, 7b are both energized. These three possible states of relays 7a and 7b are used to determine whether any notes are to be dispensed in this denomination and if so, whether a 5000 yen note is required (i.e. for digits " 5-9 "). A known comparator circuit (not shown) stops dispensing of the 1000 yen notes after delivery of the required number. Switches SWa, SWb may be operated to render the respective circuits inoperative, e.g. to render circuit 2b inoperative if only 1000 yen notes up to a maximum of nine are to be dispensed.
