Abstract: 1,043,799. Feeding webs. F. ZIMMERMANN & CO. April 22, 1965 [April 24, 1964], No. 17064/65. Heading B6B. [Also in Division B8] In a machine for selecting and packaging coins 4 of a particular size, a sorting path 3, Fig. 1 (not shown), a shoot 5, stacking bars 58, Fig. 8 (not shown), and mechanism for positioning, feeding, cutting, and folding a paper wrapper may be pre-set by means of selector switches 13, each of which corresponds to a coin of different size. The coins are supplied by a feed device 1, and pass via a sorting rail 2 to the sorting path 3, those coins not selected dropping through a shoot 6 into a container 7. The selected coins 4 after passing through the shoot 5, are counted by a device (not shown) before reaching the stacking bars 58. A gripping device (not shown) transfers a roll of coins to a rolling device by which the coins are rolled in a paper wrapper, the ends of the wrapper being turned over the ends of the roll. The wrapped rolls 9 are collected in a container 10. Pre-selection mechanism.-A setting spindle 14, Fig. 2 (not shown), has eight setting discs 16-23, each of which pre-sets a different part of the machine. Each of the discs 16-23 has eight setting pins 24, each of which corresponds to one of eight different sizes of coin. Taking the disc 16, which controls the sorting mechanism, as an example, Fig. 6 (not shown), the pins 24 vary in length, thereby enabling a setting lever 100 to be pre-set at one of eight different positions. One of a set of cams 27, which corresponds to the disc 16 is mounted on a shaft 15, may be rotated to lift the setting lever 100 clear of the setting pins thereby allowing the disc 16 to be turned. A slider 46 operated through the setting lever 100 varies the size of the sorting path 3 to allow the passage of coins of one particular diameter. The disc 17 varies the size of the shoot 5 by sliders 54, Fig. 7 (not shown), through a similar setting mechanism. The gap between the stacking bars 58 and the gap between a pair of rolling cylinders 59 are both varied by means of a disc 18. The amount of paper 11a. Fig. 10, fed between rollers 78, 79 is determined by the position of the disc 20. The height of the setting pin selected on the disc 20 determines the position of a cam-operated toothed sector 76 in relation to a gear 77 on the lower feed roller 78, and therefore varies the starting point of the drive motion to the feed roller. The longitudinal setting of a cutter 84, Fig. 11 (not shown), is varied by means of the disc 21 which enables the position of a carriage 82 carrying the cutter on a bridge 85 to be pre-set. In order to allow for different thickness of coins and the consequent different lengths of coin rolls, the position of the paper reel 11, Fig. 9 (not shown), is adjusted by the disc 19 which enables the rear flange 70 of the reel to be displaced and set at the required distance, the front flange of the reel being urged towards the rear flange 70 by a spring (not shown). The members 87, Fig. 12 (not shown), which fold the edges of the wrapper over the ends of the roll of coins slide into contact with the ends of the roll under control of a cam 74a. In order to allow for rolls of different lengths, the position at which the members 87 start their sliding motion may be pre-set by means of the disc 22. Although the stacking bars 58 and rolling cylinders 59 may have a common setting disc 18, a separate disc 23 may be provided for the cylinders 59. Operation of pre-setting controls.-On depressing one of the eight control switches 13 an electric motor 32, Fig. 4 (not shown), drives the shaft 15 through a slidable switch mechanism 41 and gears 43, 45. When the spindle 15 has turned through 180 degrees, a cam 29 operates a switch 31 to bring in a clutch magnet 33 which, by means of a changeover member 35 transfers the drive to the spindle 14. Eight control discs 25 (five only shown), on the shaft 14 begin to rotate but only that disc which corresponds to the control switch 13 which has been depressed, operates its corresponding switch 26. Each switch 26 corresponds to one of eight angular settings of the shaft 14. After the shaft 14 is set, the drive is then returned to the shaft 15 and the shaft 14 is stopped. The shaft 15 then rotates through a further 180 degrees to the position of minimum lift of the cams 27, e.g. as shown in Fig. 6 (not shown). The setting levers are thereby enabled to contact their respective setting pins under spring action and the setting motor is stopped through the action of members 28, 30. The machine is therefore automatically pre-set to a particular size of coin. The electrical circuit may be modified, Fig. 5 (not shown), to operate a setting motor 32 for each of the spindles 14,15.
