Definitions
- the invention relates to methods and apparatus for feeding articles into outwardly opening compartments of a movable stacking device.
- US-A-4244565 discloses the use of a pivoted regulating finger which can be moved into the path of an arriving article, such as a banknote, to impede its progress or can be moved away so as to remove that impedance, the degree of movement depending upon the time required to allow the rotating stacking wheel to be synchronised with the arrival of the sheet. This is a relatively complex system requiring the use of the regulating finger.
- GB-A-2169103 discloses another method for synchronising the arrival of sheets at a stacking wheel in which the arrival of a leading edge of a sheet at a predetermined position upstream of the stacking wheel is detected and then the relationship between radially outwardly opening compartments of the stacking wheel and the arriving sheet is determined and if it is found that the sheet will not be synchronised with a compartment then the stacking wheel is caused to rotate at a second, higher angular velocity for a period which varies in accordance with the degree of non-synchronisation so as to bring the compartment into line with the arriving sheet.
- WO83/00136 is similar to GB-A-2169103 in disclosing a synchronising system in which a fixed voltage is applied for a variable time to a drive motor. This results in wear which will degrade reliability.
- a method of feeding articles into outwardly opening compartments of a movable stacking device comprises
- article feeding apparatus comprises a movable stacking device having a number of outwardly opening, article receiving compartments; transport means for feeding articles to the stacking device; a sensor for sensing the passage of articles as they are fed by the transport means; a monitor for monitoring movement of the stacking device; and control means for determining whether the position of the article which is sensed by the sensor and the movement of the device as monitored by the device monitor satisfy a predetermined condition in which the article will be successfully received in a compartment of the device, and, if the condition is not satisfied, for causing the device to move at a different velocity for a fixed time which is the same for each article so that the article is successfully received in a compartment.
- step d the stacking wheel is synchronised with the transport by switching the velocity to a second, higher velocity with a fixed magnitude for a period determined in accordance with the degree of non-synchronism. If the degree of non-synchronism is small then the stacker wheel would only be rotated at the higher velocity for a short time leading to high acceleration and deceleration being required.
- the time period is fixed and the velocity varies in accordance with the degree of non-synchronism.
- the change in velocity of the stacking device will be relatively small. This serves to minimise the rate of wear of the drive mechanism for the stacking device, the disturbance of the stacking device and, where the device comprises a stacker wheel with radially outwardly extending tines, vibrations in the tines. This avoids the need for a long recovery period leading to higher article feed rates being accommodated.
- calibration factors may be included to overcome non-linear behaviour of the apparatus since the velocity applied is selectable.
- the invention is primarily concerned with rotatable stacker wheels, it could also be applied to other stacking devices which operate in a cyclic manner such as an elongate belt having outwardly opening compartments. Preferably, however, in all cases the compartments are substantially equally spaced apart.
- the predetermined condition will be satisfied if an article will enter a compartment within a gap defined between the walls of the compartment and having ends spaced from the walls of the compartment.
- the exact dimensions of the gap will be determined empirically so as to minimise the risk of fliers occuring.
- the stacking device will move at a substantially constant velocity, which may be fixed or which may be linearly related to the article feed rate except during step d).
- ⁇ 2 ⁇ /NT - ⁇ 0 ((NL + ING)/TS) (3) where NL is the length of an article (for example in mm) ING is the gap between successive articles (for example mm) and TS is the article feed speed (for example mm/sec).
- the control means determines the current position of the stacking device while one or both or a combination of the parameters NL and ING is monitored by the sensor.
- step (a) comprises sensing the arrival of each article at a predetermined position upstream of the stacking device so that the parameter NL + ING can be computed.
- the interarticle gap ING could be determined alone by sensing the passage of a trailing edge and leading edge of successive articles past the predetermined postion.
- the mechanism will deal adequately with single articles, ie.articles which are not part of a steady stream, provided that the available range of ⁇ 1, and the distance L between a compartment and the position at which an article is sensed are suitably chosen.
- Lmin TS X ( ⁇ t + device settling time) (6) and where Lmin is the minimum permissible distance between the sensor and the point at which an article enters the stacker.
- the position of the sensor is not critical and for example could be positioned sufficiently upstream of the stacking device that more than one article can be present in the transport means between the sensor and the stacking device at one time.
- the average stacking device speed ⁇ 0 can be treated as a fixed parameter or alternatively the article rate NR parameter can be monitored and used to adjust ⁇ 0 as appropriate.
- ⁇ 1 could be less than or greater that ⁇ 0.
- the apparatus shown in Figure 1 comprises a stacking device 1 which comprises a number of stacking wheels 2 mounted non-rotatably to a shaft 3 (one of the stacking wheels being shown in Figure 1). Each stacking wheel comprises a series of spiralling tines 4 between each pair of which is defined a note receiving compartment 5.
- a note transport system 6 comprises a number of pairs of opposing belts 7, 8 which define a transport path 9 terminating adjacent to the stacking device 1 at a position 10.
- Banknotes are delivered into the transport system 6 in a conventional manner (not shown) and fed upon rotation of the belts 7, 8 along the transport path 9 to the exit 10.
- the stacking wheels 2 rotate in the direction of arrow 2′ and are synchronised with note movement in the manner to be described so that as a banknote 11 exits from the transport 6 it enters between a pair of tines 4 into a compartment 5 of each stacking wheel 2.
- the stacking device 1 is rotating in the clockwise direction 2′, as seen in Figure 1, so that notes in each compartment are carried around until they engage a stripper plate 12 in a conventional manner which strips the notes from the compartments 5 to form a stack.
- FIG 2 illustrates the control system for the apparatus shown in Figure 1.
- the shaft 3 is rotated by a motor 13 whose speed is controlled by a motor drive unit 14.
- the rotational position of the shaft 3 is determined from a sensor 15 which monitors the position of a slotted disc 16 non-rotatably mounted to the shaft 3.
- the sensor 15 outputs signals corresponding to the passage of each slot in the disc 16 to a controller 17.
- the controller 17 may be constituted in hardware, software (ie. a microcomputer) or a combination of the two and uses the information from the sensor 15 to generate a motor speed control signal which is fed to the motor drive unit 14.
- the controller 17 is also connected with a sensor 18 positioned, as shown in Figure 1, to detect the passage of banknotes along the transport path 9, the arrival of the leading edge of each banknote causing an appropriate signal to be fed to the controller 17.
- the feed speed of the transport means 6 is monitored (by means not shown) and fed to the controller 17.
- each stacking wheel 2 has twelve tines 4 defining twelve compartments 5 so that the motion of the stacking device relative to the transport can be represented graphically as a cyclic motion extending through 30°.
- Figure 3 summarises the stable operating condition with the "0°" position corresponding to the tip of a tine being in line with the leading edge of a note leaving the transport, the vertical scale representing the angular rotation of the stacking wheel, "modulo 30°".
- the horizontal scale represents elapsed time.
- NP note period
- the safe angular window or gap for the arrival of notes has been assumed to be from 9° ahead of the tine to 21° ahead of the tine ie. the note should arrive within 9° of any tine.
- This gap is illustrated in Figure 1 as defined between points 19, 20 on the peripheral locus of the tines.
- the points 19, 20 are shown by horizontal lines at the 9° and 21° positions.
- Figure 4 is similar to Figure 3 but illustrates the case where a note is sensed by the sensor 18 as arriving earlier than expected. This is detected by the controller 17 which, while a downstream note is being successfully fed into the stacking device, monitors output signals from the sensor 18 so as to generate a value corresponding to the distance between the leading edge of the previous note passing the position of the sensor 18 (and now being fed to the stacking wheels 2) and the passage of the leading edge of the next note.
- This value defines the term NL + ING referred to above from which the controller 17 computes the necessary correction angular velocity ⁇ 1 in accordance the equation 3 above.
- ⁇ t is preset at a suitable value which may be, for example, 60ms.
- the controller 17 determines when the centre of the safe period is in line with the leading edge of the downstream note (position 21 in Figure 4) and at that instant the controller 17 instructs the motor drive unit 14 to increase the speed of the motor 13 to cause the shaft 3 to rotate at the angular velocity ⁇ 1.
- the controller allows the motor 13 to rotate at this higher angular velocity ⁇ 1 for the period ⁇ t and then instructs the motor drive unit 14 to cause the motor 13 to rotate the shaft 3 at the lower angular velocity ⁇ 0 at time 22.
- the result of this higher speed of rotation is to change the phase of the stacking wheels 2 relative to the incoming note so that the new note, which arrives earlier than expected, will enter into a compartment 4 through the safe gap. Assuming that successive notes then arrive at expected intervals, the stacking wheels 2 will continue to rotate at the normal lower angular velocity ⁇ 0 as shown in Figure 4.
