Definitions

• This invention relates to a device and method for sealing sheet documents or coins in a bag. It also relates to a bag suitable for use with the device and method.
• CIT companies have developed various, more or less, secure ways of handling currency in order to transport it.
• Traditionally to transport secure goods, bulky locked metal cassettes containing the sheet documents or coins were removed from cash-recycling machines by the CIT companies and moved in the CIT companies' secure vans. A number of issues have arisen by transferring the valuable goods in this way.
• the bulkiness of the cassette greatly limited the amount of sheet documents or coins that the CIT companies can transfer.
• Standard practice for the CIT companies is to remove the cassettes for cash machines, load them onto fortified trucks and transport them to a desired location.
• the size and weight of the cassettes is substantial in relation to the amount of cash contained within them, making them awkward to handle.
• the cassettes are expensive items in their own right.
• EP0852279 discloses a bag for storing cash which can be sealed after the cash has been loaded into it. This overcomes some of the problems mentioned above, being lighter and cheaper than a cassette.
• loading cash into the bag is complicated, requiring cash handling equipment to be fitted with dedicated transport elements to introduce the cash into the bag through a narrow inlet slot formed in the bag. Alignment between the bag and the transport elements is clearly critical.
• the design of the bag does not lend itself to being easily stacked with other bags of the same type because the sealed inlet slot interferes with adjacent bags. The bags are also unsuitable for use with coins.
• a device for sealing sheet documents or coins in a bag the device being adapted for receiving sheet documents or coins from the sheet document or coin processing equipment in use, the device comprising a bag retainer for holding the bag, in use, in a vertical orientation such that an open end of the bag is uppermost, thereby allowing falling sheet documents or coins discharged by the sheet document or coin processing equipment to collect in the bag, and a heat sealer for sealing the open end of the bag.
• the invention provides a device which allows bags to be loaded with sheet documents or coins simply by allowing these to fall out of the transport mechanisms of cash handling machinery at the appropriate point along the transport through the open end of the bag.
• the invention can therefore be easily used with existing cash handling machinery without extensive modification; alignment between the bag and the machinery is not critical and no dedicated transport elements are required.
• the use of bags ensures that cost can be minimised (which is important as the bags are destroyed during monitored opening as part of the cash-in-transit process) and it is easy to detect tampering as this will involve destruction of the bag or seal.
• the use of this device allows bags to be sealed whilst still within sheet document or coin processing equipment, which reduces the possibility of pilfering as may occur if the bag was removed for manual sealing.
• the device and bags can accept documents such as banknotes delivered (for example, by discharge from the transport of a banknote or other sheet document processing equipment) in a horizontal plane, which is important for efficient stacking within the bag. This is needed because a large number of banknotes must be collected in each instance for economic reasons and because the space available in banknote processing equipment is limited.
• sheet documents in this specification includes paper currency and other security documents.
• the bag retainer may comprise one or more hooks, each of which engages with a corresponding eyelet disposed at the open end of a bag in order to hold the bag in the desired position.
• the bag retainer comprises a pair of opposed runners, each of which is adapted to engage, in use, with a corresponding retaining rail on the bag.
• the pair of opposed runners lie parallel to each other.
• the bag retainer is adapted to hold the bag, in use, such that the open end of the bag is directly above a closed end of the bag, thereby allowing vertically falling sheet documents or coins discharged by the sheet document or coin processing equipment to collect on the closed end of the bag.
• the combined action of the device and the bag is to ensure that bank notes or other rectangular documents "float" down into the bag in an ordered manner and form a neat stack in the bottom of the bag. This maximises stacking potential, both in terms of efficient use of space within the bag and stacking of the filled bags after sealing.
• the bag structure it is useful for the bag structure to be such that when it is held open with the open end above the closed end, the rectangular closed end lies flat. This can be achieved through suitable choice of bag material or some kind of stiffening means for the closed end.
• the stiffening means is a wire frame.
• the heat sealer may comprise a first sealing bar movable between a first position in which a bag may be brought into engagement with the bag retainer and a second position in which a first heating element mounted on the first sealing bar is brought into contact with a bag, in use.
• the heat sealer preferably further comprises a pressure bar disposed in opposition to the first sealing bar when in the second position such that the first sealing bar and pressure bar trap the bag, in use, between them.
• the heat sealer may further comprise a second sealing bar movable between a third position in which a bag may be brought into engagement with the bag retainer and a fourth position in which the second sealing bar is disposed in opposition to the first sealing bar when in the second position such that the first and second sealing bars trap the bag, in use, between them.
• a second heating element is mounted on the second sealing bar.
• first and second sealing bars are pivotally movable between the first and second positions and third and fourth positions respectively.
• the second and fourth positions are such that first and second sealing bars are symmetrically arranged and move by equal amounts between the first and second positions and the third and fourth positions respectively.
• the bars By allowing the first and second sealing bars to retract into the first and third positions, the bars can be stowed in a position where they will be out of the way of the bag during loading and unloading. Aside from making loading and unloading operations easier, this also results in a very compact device because the welding bars can be positioned at the same level as the bag retainer. In practice, we have found that a device having a depth of only 30mm (when the bars are retracted into the first and third positions) can be realised.
• the device may further comprise an opening, for example in the bag retainer, through which falling sheet documents or coins discharged by the sheet document or coin processing equipment may pass, in use, into the open end of the bag.
• the opening is defined by a pair of flaps, each of which is movable between a first position in which a bag may be brought into engagement with the bag retainer and a second position in which the flaps hold the open end of the bag so that it does not impede the passage of falling sheet documents or coins into the bag.
• Each of the pair of flaps may clamp a respective portion of the open end of the bag against a respective side wall of the device when in the second position.
• the device may also comprise at least one finger movable between a first position in which a bag may be brought into engagement with the bag retainer and a second position in which the finger contacts the side of the bag, in use.
• the device comprises a pair of opposed fingers, each of which is movable between a first position in which a bag may be brought into engagement with the bag retainer and a second position in which it contacts a respective side of the bag, in use.
• the device may further comprise a controller adapted to cause the or each finger to move repeatedly between the first and second positions, thereby shaking the bag to ensure sheet documents do not adhere to the bag. This assists in dislodging documents that have become attracted to the bag by static electricity.
• kits comprising a device as described above and at least one bag.
• the closed end of the bag is rectangular and the bag has parallel sides perpendicular to the closed end.
• the bag structure is preferably such that when it is held open with the open end above the closed end, the rectangular closed end lies flat.
• a method for sealing sheet documents or coins in a bag comprising holding a bag in a vertical orientation such that an open end of the bag is uppermost, thereby allowing falling sheet documents or coins discharged by a sheet document or coin processing equipment to collect in the bag, receiving at least one sheet document or coin from the sheet document or coin processing equipment in the bag, and sealing the open end of the bag.
• the method typically further comprises engaging a bag with a bag retainer for holding the bag in a vertical orientation such that the open end of the bag is uppermost.
• the method will also typically further comprise disengaging the bag from the bag retainer after the open end of the bag has been sealed.
• the method preferably further comprises holding the bag such that the open end of the bag is directly above a closed end of the bag, thereby allowing vertically falling sheet documents or coins discharged by the sheet document or coin processing equipment to collect on the closed end of the bag.
• the step of sealing the open end of the bag may comprise moving a first sealing bar from a first position in which the bag may be brought into position for holding in the vertical orientation such that the open end is uppermost to a second position in which a first heating element mounted on the first sealing bar is brought into contact with a bag.
• the method may further comprise trapping the bag between a pressure bar disposed in opposition to the first sealing bar when in the second position.
• the step of sealing the open end of the bag further comprises moving a second sealing bar from a third position in which the bag may be brought into position for holding in the vertical orientation such that the open end is uppermost to a fourth position in which the second sealing bar is disposed in opposition to the first sealing bar when in the second position such that the first and second sealing bars trap the bag between them.
• first and second sealing bars move pivotally between the first and second positions and third and fourth positions respectively.
• the second and fourth positions are such that first and second sealing bars are symmetrically arranged and move by equal amounts between the first and second positions and the third and fourth positions respectively. As mentioned above, this ensures that the bag shape is not distorted during sealing helping the bag to lie flat to assist stacking.
• the method normally further comprises activating the first heating element, thereby sealing the bag.
• the method may also further comprise activating a second heating element mounted on the second sealing bar.
• the method further comprises clamping the open end of the bag in a defined position such that the open end of the bag does not impede the passage of falling sheet documents or coins into the bag.
• the method may also comprise, prior to the step of sealing the open end of the bag, moving at least one finger from a first position in which the bag may be brought into position for holding in the vertical orientation such that the open end is uppermost and a second position in which the finger contacts a gusset portion in a side of the bag, thereby assisting the folding of the gusset portion.
• the method preferably further comprises, prior to the step of sealing the open end of the bag, moving a pair of opposed fingers from a first position in which the bag may be brought into position for holding in the vertical orientation such that the open end is uppermost and a second position in which each finger contacts a gusset portion in a respective side of the bag, thereby assisting the folding of the gusset portions.
• the method further comprises moving the or each finger repeatedly between the first and second positions, thereby shaking the bag to ensure sheet documents do not adhere to the bag. As mentioned above, this assists in dislodging documents that have become attracted to the bag by static electricity.
• a bag comprising open and closed ends joined by a plurality of side walls, at least one of which is gusseted; a frame for holding the closed end in a desired shape; and a retaining element by which the bag may be retained in a device according to the first aspect, in use.
• This bag provides many advantages over prior art bags. Firstly, the use of an open end allows sheet documents and coins to be easily collected in the bag as discussed above. Further, the use of a frame assists with holding the bag's shape as the documents or coins are collected. The frame is also much cheaper than the use of a solid plate, as has been used in the prior art.
• the retaining element allows the bag to be easily brought into engagement with the device of the first aspect so that it may be held with its open end in the correct position.
• the gussets allow the bag to expand in width to accommodate sheet documents and to lie flat when empty or partially filled.
• the frame is rectangular so as to hold the closed end of the bag in a rectangular shape and the bag has four side walls, of which two opposing side walls are gusseted.
• the retaining element comprises a pair of mounting rails disposed at the top of the two opposing, gusseted side walls.
• Each mounting rail may have an articulated joint, each articulated joint being co-axial with a central axis on a respective one of the gussets such that the mounting rails may fold along with the gusset.
• each of the four side walls has a first thickness
• additional layers of the first thickness are provided in a sealing region on each of the non-gusseted side walls such that when the gusseted side walls are folded inwardly the sealing region has a uniform thickness
• a sheet document or coin processing apparatus comprising a device according to the first aspect.
• a sheet processing apparatus preferably includes a sheet feed mechanism for delivering the sheet documents to the bag.
• a sheet feed mechanism for delivering the sheet documents to the bag.
• the sheet feed mechanism imparts a slight upward curvature or fold to the sheets.

In this position, the movable flaps 8a, 8b clamp the sides of bag 1 1 against the side walls of bag retainer frame 1 and thereby serve to expand bag 1 1 to conform to the distance between the flaps 8a, 8b. Thus, a smooth, unobstructed passage is provided for sheet documents or coins through the bag retainer frame 1 into the bag 1 1 .
• the flaps 8a, 8b are pivotally movable between the open and closed positions about respective pivots 12a, 12b as a result of the actuation of a lever arm 9.
• the lever arm 9 may be moved by a motor (not shown) or solenoid (not shown) coupled to it.
• the clamping action of the flaps 8a, 8b (along with a frame in the bag 1 1 described below) holds the bag 1 1 in a rigid, rectangular format, which again provides a smooth, unobstructed passage for sheet documents or coins falling into the bag 1 1.
• the weight of the sheet documents or coins assists holding the bag in this format as they fall in.
• the flaps prefferably be jogged or caused to oscillate slightly as documents or coins fall into the bag. This is particularly useful in connection with documents to help to ensure that they are neatly stacked.
• the jogging or oscillating motion would be much smaller than the motion between the open and closed positions described above and could be achieved through the use of a small motor or other driver.
• the preferred bag to be described below has a rectangular closed end. This is deliberate, not so much as the ideal container for " rectangular " cash notes but in order to cause the notes to " float “ down into the bag from host coin processing equipment in an ordered manner to maximise stacking potential. In this respect the bag is not simply a loose sack. Further research on bag features has indicated that efficient free stacking is an important issue as most prior art bags need an artificial device to improve stacking.
• Figure 3 depicts a front view of the device and shows a mechanism comprising a pair of fingers 13a, 13b which assist with clearing the sealing region on the bag and folding the gussets.
• the fingers 13a, 13b are arranged to rotate about respective pivots 14a, 14b such that when in use, the fingers 13a, 13b press in on the gusseted sides of the bag (as shown by the dashed lines), thereby folding in the gussets 15a, 15b so that a sealing region near the open end of the bag 1 1 is straight and even and may be neatly clamped by the welding bars 4, 5 for sealing.
• a smooth, straight seal is formed, allowing tampering to be more readily identified.
• the fingers 13a, 13b may be repeatedly moved at high speed between the position shown in solid lines and the position shown in dashed lines so as to shake the sides of the bag 1 1 in order to dislodge any sheet documents which have adhered to the bag 1 1 , for example due to attraction by static electricity.
• the fingers 13a and 13b are not be necessary and sheet documents will simply float to the base of a bag with a rectangular closed end in a neat stack.
• the welding bars 4, 5 are activated, thereby forming a seal in the seal region of bag 1 1 .
• FIG. 4 shows a cross-section through the heat sealer.
• Welding bar 5 carried by arms 3a and 3b, has an electrically and thermally insulating strip 16 (for example, made form mica) fitted along its full length.
• An impulse heating element 17 is stretched over the insulating strip 16 and connected at each end of the welding bar 5 to an electrical supply (via an electronically controlled switch, such as a relay).
• a polytetrafluoroethylene (PTFE) sheet 18 is wrapped over the element and secured.
• a plastic strip 19 running along the full length of welding bar 5 provides an edge to grip the bag in conjunction a plastic strip mounted on the other welding bar 4 as described below.
• Welding bar 4 carried by arms 2a and 2b, provides the reaction force to welding bar 5 when they are driven together for sealing.
• a sliding member 20 which is urged away from welding bar 4 by a spring 21. This allows any inconsistencies or unevenness in the sealing region of bag 1 1 to be taken up.
• the front of the sliding member 20 is also fitted with an insulator 22, which is also covered with a PTFE sheet 23.
• a plastic strip 24 running along the full length of welding bar 4 provides an edge to grip the bag in conjunction with the plastic strip 19 mounted on welding bar 5.
• the spring-loaded sliding member 20 applies pressure against the heating element 17 with a bag trapped in between.
• the continuing closure of the welding bars 4 and 5 causes the plastic strips 19 and 24 to clamp the bag.
• the purpose of the clamping is to stop the bag dropping down under its own weight when the welding process causes the sealing region to become molten.
• the idea of the sprung bars is to ensure even welding.
• a bag cannot be removed from the machine until all of the flaps 8a, 8b, the fingers 13a, 13b and the welding bars 4, 5 have been retracted. This ensures that the bag cannot be removed from the device until it has been sealed and released, which reduces the opportunity for pilfering and tampering, thereby improving the security of the bag.
• FIGs 5a and 5b show the bag 1 1 in detail.
• the bag 1 1 has mounting rails 25 on each of two opposed, gusseted sides of the bag 1 1. Only one of the mounting rails is shown in Figure 5a.
• the bag 1 1 is welded at the seams.
• the gussets have a gusset fold point 26, the position of which is defined by three gusset folds 27a, 27b, 27c emanating from the gusset fold point 26.
• a similar gusset fold point (defined in part by fold 27c) will be defined near the closed end of the bag and the opposite side of the bag has corresponding gusset folds and gusset fold points.
• the mounting rails 25 may be engaged with the runners 10a, 10b as described above.
• the mounting rails 25 each have an articulated joint 28 break in line with the gusset fold 27c such that when the fingers 13a, 13b press in the gusset folds, the articulated joints 28 allows the mounting rails 25 to conform to the folds. This allows the bag 1 1 to close completely at the open end giving a better fold and seal.
• Each of the articulated joints 28 may be provided by simply abutting two plastic tubes or rods within a sleeve formed in the bag 1 1 to form each mounting rail 25, the joint being provided by hinging action at the abutment.
• the closed end 29 of the bag shown in Figure 6a is held in a rectangular shape by a rectangular wire frame (not shown) within the bag 1 1 corresponding to the shape of the open end when inserted in the device.
• FIG. 6a and 6b shows an improvement to the bag 1 1 in the sealing region.
• the sides of the bag extend to form two flaps 30a, 30b at the open end. These flaps 30a, 30b are folded over the sides as shown before sealing.
• the flaps 30a, 30b ensure that the bag has four thicknesses of material across the entire sealing region, both in the folded gussets (where the thickness is made up of the gusseted sides and the plain sides) and in the remainder of the sealing region (where the thickness is made up of the plain sides and flaps 30a, 30b). This ensures that the bag 1 1 has a uniform thickness in the sealing region and assists with the sealing process.
• the width and length of the bag 1 1 are adjusted to accept the maximum dimensions of banknotes or other sheet documents required to be collected and its height is adjusted to suit the volume of documents or banknotes intended for collection.
• Each of the mechanisms described above are electrically driven by motors or solenoids as appropriate operated by a suitable process controller, which may be linked to sheet document or coin processing equipment to which the device is coupled.
• the device described will generally be used with a sheet document processing equipment (or coin processing equipment) such as a banknote counter or sorter.
• a sheet document processing equipment or coin processing equipment
• the device will be placed beneath a discharge location of the sheet document processing equipment such that any sheet documents (e.g. banknotes) discharged at that location will fall through the opening 7 into a bag 1 1 fitted to the device in the manner described above.
• the bag 1 1 may then be sealed as already described and removed from the device by cash-in-transit personnel.
• FIG. 7 shows a sheet feed mechanism suitable for incorporation into sheet document processing equipment to discharge notes to a bag sealing device as described above.
• the figure shows a rectangular sheet document 40 such as a bank note about to exit the feed mechanism which comprises a pair of rollers 41 and 42 mounted on drive axles 43 and 44 respectively.
• roller 41 is driven in the clockwise direction as shown
• roller 42 is driven in the opposite direction and the sheet document 40 is fed in the direction of the arrow shown on the document.
• the rollers have mating curved surfaces which together form a slight transverse bend extending along the longitudinal direction of the sheet document.
