Description

The subject of the present invention is a machine for sorting, counting, stuffing and / or distributing coins.

Machines for sorting and counting coins, or for stuffing them or bagging them, are already well known and used in sectors of activity where large quantities of coins are handled daily.

These machines are generally very sophisticated and complex.

Thus, in a known sorting-counting machine, a rotary distribution plate raises the pieces, previously dumped into a feed hopper, to a narrow ramp, the width of which is substantially equal to the thickness of a piece , that they descend while rolling on their edge.

Deflectors are fixed above the ramp and at decreasing distances from it, each distance being just less than the diameter of a part. Thus, each deflector deflects the parts, the diameter of which is just greater than its distance from the ramp, and causes them to fall into the tube which is associated with it.

The parts, which have a diameter less than the distance between the deflector considered and the ramp, are not deflected and continue their descent until they meet the appropriate deflector. The parts are thus sorted in decreasing order of size, in the direction of the descent of the ramp. After a second sorting, they are collected in bags or stuffed into preformed paper tubes.

In another sorting-counting machine, the sorting of the coins is carried out by a very sophisticated electronic selector.

Such machines are known for example from US Pat. No. 3,520,833. They generally include at least one motor for rotating the distribution plate, as well as numerous electronic components. They are of a very complex design, therefore very expensive and prone to breakdowns, due to the large number of components used in their manufacture.

They are also very specialized: there are sorters, sorters-counters, cartoners, but no machine that can perform sorting, counting and cartoning as well as the distribution of coins, and are especially suitable for handling of coins in very large quantities, some sorters being able, for example, to sort up to 2,000 coins per minute.

These machines are therefore not very suitable, for example, for small shops or small bank branches, in which smaller quantities of coins are handled.

A machine for sorting and packaging coins with a less sophisticated design because it is older, is known from patent FR-652,531. In this machine, the coins descend a ramp-forming channel and are sorted by longitudinal slots arranged laterally with respect to to the canal. Such a device makes it possible to sort only coins having very different diameters and does not allow to sort current coins, whose diameters differ by a few tenths of a millimeter.

The object of the present invention is to remedy these drawbacks and in particular to produce a machine making it possible to carry out sorting of coins as well, even when they have diameters which differ very little, of the order for example, of a few tenths of a millimeter, as their counting, their packaging and their distribution, that is to say allowing both to carry cartridges of coins such as those used in banks, and to make change.

Another object of this invention is to provide a machine of simple, reliable, robust and inexpensive design, suitable for daily use in small shops or bank branches.

To this end, in the machine according to the invention, which is of the type comprising a ramp for sorting parts and tubes, located along this ramp, and each of which is capable of receiving a given type of part, the tubes for receiving the pieces are placed under the sorting ramp, in order of increasing size in the direction of descent of this ramp, and this ramp, of width at least equal to the largest diameter of the piece to be sorted, has an outer rim and, at each receiving tube, an associated hole for the passage of each piece in the appropriate tube, and an associated sorting plate, of adjustable position, projecting on the edge of the hole opposite the outer edge of the ramp, so that the distance between it and the edge of the ramp is just greater than the diameter of the parts intended for this tube. This way, the part slides flat on the sorting ramp against its rim, and when the distance between this rim and a sorting plate is just greater than the diameter of the part, the latter tilts and falls into the associated receiving tube.

i In this sorting mode, the pieces are sorted in order of increasing size, in the direction of descent of the sorting ramp.

In order to prevent a part, driven by its kinetic energy, from falling into the next hole, each hole for the passage of the parts in each associated receiving tube has a length greater than the diameter considered, so that the part falls well into the corresponding tube.

Preferably, the angle of longitudinal inclination of the sorting ramp with respect to the horizontal is between 15 ° and 20 °, this angle being large enough to bring the pieces down, and small enough so that these n do not acquire too much kinetic energy.

In addition, so that each piece slides against its outer edge, the sorting ramp has a slight transverse inclination towards the outside. An auxiliary ramp, inclined in the opposite direction to the sorting ramp, is placed upstream of the latter, so as to form an elbow with it. This auxiliary ramp and the bend it forms with the sorting ramp cause the parts to separate and slow down before they engage on the sorting ramp.

In order to prevent two superimposed pieces from engaging on the sorting ramp and, consequently, not being properly sorted, a selection bar is placed upstream of the sorting ramp, parallel to its flat surface, so to leave only a small rectangular passage opening, of width and height slightly greater respectively than the largest diameter and the greatest admissible workpiece thickness.

According to an advantageous embodiment of this machine, each sorting plate associated with each receiving tube is formed by a plate having an oblong hole for its fixing by screws to the sorting ramp. In this way, the position of each of these plates can be adjusted according to the diameter of each of the pieces to be sorted. Recesses of a depth equal to the thickness of the sorting plates are provided on the sorting ramp at the location of these said plates, in order to obtain a substantially flat sliding surface for the parts.

For the use of this machine for blocking coins, a support bar is provided at the lower end of each receiving tube, each bar being able to move between a rest position, in which it closes said tube and at which it is automatically brought back by a return spring, and a retracted position in which it discovers the end of said tube and frees the parts contained in this tube for their packaging in a sachet.

According to a particularly advantageous embodiment of this machine, each support bar slides in a U-shaped profile fixed behind all of the receiving tubes and provided with two rectangular openings respectively on its front and rear wings for the passage of each plate. support, the return spring of each bar then being fixed between a part of this bar and the front wing of this profile, and each bar having, at the front, a flap allowing it to be pushed back to release the parts contained in the corresponding tube.

For the packaging of coins, each sachet is threaded onto a rigid packaging sleeve, the inside diameter of which is equal to that of the coins to be bagged, the length of which corresponds to the height of a pile of a determined number pieces of this diameter, and which can be placed under the tube for receiving these said pieces by pushing the support strip by its front flap. The column of parts contained in the receiving tube is then released at its base and descends inside the cartridge sleeve on which the sachet is fitted.

When the encasing sleeve contains the desired number of parts, it then suffices to remove it, the support bar then returning to its rest position and closing the receiving tube again.

The pieces fall from the packing sleeve into the bag, which is about twice the length of the stack height of the pieces to be packed. Once the pieces have been introduced into this sachet, simply twist the sachet below the cartridge tube and slide the latter onto the stack of pieces to turn the sachet over, perfect its closure, and thus form a cartridge of the number of pieces desired in each type of piece.

Preferably, each sachet is formed by a tube of material transparent plastic, closed at one end and provided at its other end with a tab which facilitates the introduction of a cartridge sleeve into the bag.

Advantageously, each bag is formed from a rectangular plastic sheet folded twice on itself, so as to present, at its closed end, an inverted V-shaped bellows, and on which welds are made and transverse cuts, each of which forms one side of the bag. Of course, there is a bag adapted for each type of parts.

During the operation of this machine as a money dispenser, there is provided, on the one hand, a dispensing tank capable of being fixed on the machine and having a first substantially flat part capable of being engaged under the lower end of each tube receiving, at a distance from this end slightly greater than the thickness of the part received by said tube, by pushing the support bar associated with this tube, and a second concave part located below the first part for receiving coins, and, on the other hand, means associated with each reception tube for ejecting the coins from each reception tube, one by one into the distribution tray.

According to a simple embodiment of the invention, the means for ejecting the coins are formed, on the one hand by an ejection bar capable of sliding in the U-profile between a rest position at the rear of the U-shaped profile, to which it is automatically brought back by a return spring, and a working position at the front of the U-shaped profile, in which it comes under the lower end of the associated receiving tube and pushes the workpiece the first part of the distribution tray, on which it is supported, in the second part of this tray, and, on the other hand by an ejection rod, integral with this ejection bar, and whose operation moves this bar from its rest position to its working position.

Each return spring of each ejection strip is mounted between a part of this strip and the rear wing of the U-shaped section, and is less powerful than each return spring of each support strip, and each ejection strip has a tab capable of coming to bear against a complementary tab of each associated support bar, so as to be driven by the latter when it returns to its rest position under the associated receiving tube. In this way, the two ejection and support bars are coupled and operate together when the machine is used for cartridge sealing.

The machine for sorting, stuffing, counting and distributing coins (1), represented in FIG. 1, is formed mainly by a block (2) of generally parallelepipedal shape, and by a distribution bin (3) which can be adapted on this block (2).

The adaptation of the distribution tray (3) on the block (2), shown in Figure 2, cancels the packing function of the latter and only allows the distribution of parts (1) one by one.

On the vertical front face of the block (2) is fixed a sorting ramp (4) inclined by about 15 ° to 20 ° relative to the horizontal. An auxiliary ramp (5) is fixed upstream of the sorting ramp (4), with an opposite slope from the latter, so as to form an elbow (6). Above the upper end of this auxiliary ramp (5), there is a chute (7) for receiving coins (1), formed by a knockout (2a) of the main block and limited at the front by a plate retainer (8) serving at the same time to channel the parts (1) of this chute (7) in the direction of the auxiliary ramp (5). The parts (1) introduced into the receiving chute (7) descend by gravity the auxiliary ramp (5) and are braked by the elbow (6) before engaging on the sorting ramp (4), with kinetic energy scaled down.

A selection bar (9), placed at the outlet of the elbow (6) in an intermediate position between the extension of the auxiliary ramp (5) and the perpendicular to the sorting ramp (4), provides a rectangular opening (9a) of width and height respectively 0.1 mm greater than the largest diameter and the greatest thickness of workpiece. This bar (9) further contributes to the slowing down of the parts (1) and only allows the unitary introduction of the parts (1) on the sorting ramp (4), that is to say one by one; it avoids, in particular, the engagement of two pieces superimposed on this ramp (4). Due to the position of its opening (9a) located in the outer part (6a) of the elbow (6), this bar (9) also directs the parts (1) outwards, so that they slide on the sorting ramp (4), against its outer edge (4a). This ramp (4) is also slightly inclined outward in the transverse direction, so as to hold the parts (1) against its edge (4a) during their descent. This ramp (4) has eight holes (4b), one hole for each type of part, and eight associated plates (10) performing the. sorting according to the diameter of the pieces (1). These holes (4b) do not touch the outer rim (4a), but on the contrary are 3 to 4 mm apart, so that the sorting ramp (4) has a return (4d) at their level (Figure 3) , which serves as a support for coins (1). The sorting plates (10) are fixed by screws in complementary recesses (4c) of the ramp (4), so that the latter has a planar sliding surface, and each have, for their fixing, an oblong hole ( 10a) for adjusting their position on the sorting ramp (4). A tube (11) for receiving the parts (1) is placed vertically under each hole (4b). These tubes (11) are formed by assembling a part (2b) of the main block having semi-cylindrical columns and a transparent plate (12), of complementary shape (cf. FIG. 3).

These receiving tubes (11) and the holes (4b) have a diameter increasing from right to left, as illustrated in FIG. 1, that is to say in the direction of descent of the sorting ramp 4. The diameter of each receiving tube (11) corresponds to the diameter (1) of a piece (1) to be sorted.

Each sorting plate (10) is placed at a distance x from the flange (4a) of the sorting ramp (4), just greater than the diameter of the piece it has to sort (increased by 0.1 mm), to hold account for possible deformations of the parts (1).

The parts (1) introduced into the receiving chute (7) descend the auxiliary ramp (5) by gravity, are slowed down at the elbow (6), separated and directed by the selection bar (9) and finally engage , one by one, on the sorting ramp (4) and with a reduced speed.

As shown in Figure 3, these parts (1) slide flat on the sorting ramp (4) against its edge (4a). As soon as a part (1) arrives on a hole (4b) with which is associated a selection plate (10), it is supported at its base by the return (4d) of the sorting ramp (4) and its part upper by the selection plate (10), unless the distance from the latter to the rim is just greater than the diameter of said part (1). In this case, the coin (1) being supported only at its base and no longer at its upper part, falls into the hole (4b). Otherwise, the coin (1) continues its descent by sliding on the sorting ramp (4), until it encounters a hole (4b) whose positioning of the sorting plate (10) is suitable for dropping it in the hole (4b), then in the tube (11).

The parts (1) are thus sorted in order of increasing diameter, in the direction of descent of the ramp (4). The holes (4b) are slightly elongated to ensure that a part (1) falls well in the appropriate tube, even if it has a significant kinetic energy.

When the pieces are sorted, the machine according to the invention makes it possible either to count them and to block them, or to distribute them one by one.

Figure 4 shows in more detail the mode of use of this machine for counting and cartoning of sorted parts. Each receiving tube (11) is closed at its lower end by a flat support strip (13) of rectangular shape, the front end of which is folded down so as to form a flap (13a) and which further comprises a lug (13b) for hanging a return spring (14).

This support bar (13) can slide in openings (15a) and (15b) formed respectively in the front wing and in the rear wing of a U-shaped profile (15) fixed behind the front panel of the machine. . Each support bar (13) can slide between a rest position in which it closes the tube (11) [right bar (13) in FIG. 4] and to which it is brought back automatically by the spring of return (14) stretched between its tab (13b) and the front face of the profile (15), and a working position in which it releases the lower end of the tube (11) and releases the parts (1) [bar (13 ) on the left in Figure 4]. Once the pieces (1) are sufficient in a tube (11), they can be put in a bag (16) to make cartridges of a number of pieces determined and approved by the banks according to the type of pieces .

The number of pieces (1) contained in each receiving tube (11) is indicated by marks (21) placed next to each tube.

A bag model (16) is provided for each type of part, depending on the diameter of the parts and their number in the cartridge to be made. Each bag (16) has, at its closed end, a bellows (16a) and, at its open end, a tongue (16b), and is formed in a transparent plastic sheet folded twice on itself, welded and cut transversely.

These bags (16) have at the base a base diameter (16c). smaller, corresponding to the diameter of the corresponding parts, and continuing over a height equal to that of the cartridge to be made. They have, at their upper part [on the side of the tongue (16b)], a larger diameter (16d), corresponding to the outside diameter of the bagging sleeve (17), and continuing over a length substantially equal to the height of the cartridge to be made. The small diameter (16c) thus makes it possible to tighten the parts (1) well in each cartridge formed. The length of the sachets (16) is thus substantially twice the height of the corresponding cartridge.

The advantage of a transparent bag (for example compared to paper rolls) is that the parts are easily recognizable.

To facilitate the sealing of each type of part (1), a rigid sealing sleeve (17) is provided. Each sleeve (17) has an internal diameter and a length corresponding respectively to the diameter of each type of piece and to the height of the stack formed by the number of pieces of this type desired in each sachet.

Semi-cylindrical housings (22) are provided on the front face of the block (2) for the storage of the sleeves (17).

To carry out the packaging, the appropriate packaging sleeve (17) is threaded into the bag (16) using the tongue (16b) without pushing it to the bottom, but leaving an approximate length of bag equal to the height of the stack of coins to form the cartridge (Figure 8). The sleeve (17), with the bottom of the bag folded under it, is then placed under the receiving tube by pushing the support bar (13) by its rim (13a). The parts (1) are then released and fall into the sleeve (17) until it is full. The latter is then removed with the appropriate number of pieces determined by its length and the pieces then fall into the bottom of the bag, completely freeing the sleeve (17), while the bar (13), released, returns to close the receiving tube associated (11).

Support surfaces (23) are formed, at different levels, under each receiving tube (11), on the front face of the main block (2), so that their respective distance from each associated tube (11) is equal to the length of the corresponding inserting sleeve (17).

The sachet (16) is then twisted, as shown in FIG. 9, as close as possible to the last piece of the stack, that is to say to the top piece. This encloses the stack of pieces, the sleeve (17) is slid down and the bottom stack is made to cross, from bottom to top through the sleeve (17), the stack of pieces thus bagged and twisted in its part. superior. The upper part of the bag (16) gradually disengages from the sleeve (17) to fall back upside down on the stack of parts and thus prevent the twist of the bag from untwisting. We then obtain the configuration of Figure 10, in which the bag (16), turned on itself, is closed reliably and forms the desired cartridge.

Each cartridge of parts thus obtained can be easily opened, either by releasing the part of the sachet folded over the cartridge and untwisting the twist, or by puncturing the sachet with the nail, between two parts and by opening it in two.

Note that markers (21) placed next to each tube reception (11) allow to know the quantity of parts stored in this tube, and in particular, to verify that this quantity is sufficient (greater than or equal) to the regulatory number for the packaging of this type of part.

To use this machine for unitary distribution of parts, there is a distribution tray (3) adapted to the block (2) by means of a hinge (2c, 3c) placed on the left, and a clip (2d , 3d), grasshopper type, placed on the right. This tank (3) comprises a substantially flat part (3a) and a concave part (3b) intended to receive the parts falling from the receiving tubes (11). When it is hooked onto the main unit (2), the distribution tray (3) pushes by its rear part (3e) each support bar (13) by its flap (13a), so that each piece (1) located at the lower end of each tube (11) bears on the part (3a) of this tank. This part (3a) has bearing faces (3f) at different levels, opposite each tube (11), so that the distance between the lower end of each tube (11) and the bearing face (3f) associated is slightly greater than the thickness of each piece received in said tube, and that it can pass only one piece at a time from the tube (11) in the tray (3).

The ejection of each part, one by one, into the distribution tank (3) is carried out using an ejection bar (18) and an ejector rod _. n (19) integral with this bar.

Each ejection bar (18) is associated with a receiving tube (11) and can slide in the openings (15a) and (15b) of the U-profile, between a rest position occupied by the right bar (18) in FIG. 5, in which it projects behind the U-shaped profile (15), and towards which it is automatically brought back by a return spring (20), and a working position occupied by the bar (18) on the left in this same FIG. 5, and in which it projects in front of the profile (15), passes between the bearing face (3f) and the lower end of the associated tube (11), and ejects the part (1) lower.

The return spring (20) of the ejection bar (18) is stretched between a latching lug (18a) of this bar and the rear face of the profile (15) and is less powerful than the return spring (14 ) of the support strip (13), so that these two strips are coupled, when the machine is used for cartridge sealing, by means of the tab (13b) of the support strip (13) and a tab (18b) of the ejection bar (18), the tab (18b) being driven by the tab (13b), against the action of the return spring (20) of the bar d ejection (18), upon return of the support bar (13) to its rest position.

When using this machine for dispensing, the return spring (14) of the support bar (13) is neutralized because the latter is kept pushed back by the rear part (3e) of the distribution tray , and the ejection bar (18) only undergoes the action of its own return spring (20).

Each ejection rod (19) is constituted by a metal rod fixed to the rear of each ejection bar (18). When the ejection bar (18) is in the rest position, the operation of the ejection rod (19) moves the bar (18) into its working position in which it remains as long as the action on the rod lasts. (19). As soon as it is released, the bar (18) is automatically returned to its rest position by its return spring (20), also driving the ejection rod (19) to its rest position. In this way, the parts (1) can be ejected one by one out of each tube (11).

This machine can therefore be used in small shops and small bank branches for sorting, counting and cartridge sealing of coins, as well as for making change.

In the latter mode of use, it may be advantageous to provide, under the distribution tray (3), a drawer for storing banknotes.

Of course, the present invention is not limited to the sole embodiment of this machine, described above by way of nonlimiting example; on the contrary, it embraces all of the variant embodiments employing equivalent means.
