The invention relates to a filling machine for filling products, especially liquid foods, into packaging containers made of composite cardboard material. The collection and unfolding of flat folded packaging liners to produce packaging containers from a filling machine magazine has so far required relatively large force of the clamp. In order to reduce the clamp forces necessary to collect and unfold the packaging linings and to avoid the noises that are formed when unfolding, as well as malfunctions, a filling machine is proposed, in which, with the help of a guide, the packaging liner removed from the loader is only partially assembled parallelogram type and at least one of the two fasteners for receiving an outer folding corner of the partially assembled liner can be moved back and forth between an initial position and a final position, in the final position of the mobile fastening element the cross section of the packaging coating received by the two fastening elements is rectangular.

    [001] Filling machines for filling products, especially liquid foods, in packaging containers made of composite cardboard material, are known in the art. Regarding the structure of the known filling machines, reference is made, for example, to EP 0 936 992 B1 and DE 41 42 167 C2.
    [002] The normally square packaging containers are manufactured only in the filling machine, for reasons of better transport capacity, from packaging cutouts with folding corners and welded to form packaging linings. Each flat-folded packaging liner has four packaging walls separated from each other by internal and external folding corners that evolve in parallel. In the outer folding corners of the flat-folded packaging liner, respectively, an acute internal angle is included between the packaging walls. The inner folding corners of the flat-folded packaging liner are arranged between the outer folding corners. In the inner folding corners of the flat-folded packaging liner, an obtuse internal angle is respectively included between the packaging walls. As long as the packaging walls have corresponding dimensions, the internal folding corners divide the section between the outer folding corners in half.
    [003] The packaging linings folded flat are sent from a loader to at least one conveyor line of the filling machine. In the loader, the packaging liners are arranged one after the other as a stack, usually vertically. On one side of the loader that points in the direction of the transport line, two of the four packaging walls of the respective front cover of the packaging are free. On the stack, a force is exerted on its back side towards the collection side, for example from a spring or a linear drive, to move the coatings of the battery packaging towards the collection side.
    [004] A collection and folding device comprises a clamp for capturing one of the two free packaging walls on the collection side of the loader, a guide for the other of the two free packaging walls, as well as fastening elements arranged behind the guide in the direction of movement to retract the outer folding corners of the unfolded package liner.
    [005] The collection and unfolding device begins by folding the packaging liner folded flat into a packaging liner that forms a rectangular cross-section. The unfolded packaging liner is received by a transport device. The packaging containers produced from the packaging liners are sterilized, filled and then closed along the conveyor line of the filling machine. The manufacture of the bottom of the packaging is normally carried out immediately before filling. Then, the packaging head is normally made.
    [006] As a transport device, transport wheels or conveyor belts can be used in particular with bag-shaped receipts for packaging linings or unfolded packaging containers. The progressively rotating transport wheels have several parallel receipts that extend radially outwards. Receptions are usually constituted as mandrels, where unfolded packaging liners or packaging containers are placed; there is also talk of a mandrel wheel. In another version of one of these transport wheels, each reception includes several arms or profiles which touch directly directly beside the folding corners of the unfolded packaging liner or packaging container. In this case, the receipts form cells, where the packaging linings or unfolded packaging containers can be inserted; there is also talk of a cellular wheel.
    [007] The following explains in detail a technologically up-to-date filling machine with a collection and unfolding device from the company SIG Combibloc GmbH in D-52441 Linnich by means of Figures 1 a) - 1 d):
    [008] The packaging linings (1) folded flat are reserved vertically in the loader (2) of the filling machine. Each flat-folded packaging liner (1) has four packaging walls (5a, 5b, 6a, 6b) separated from each other by external (3a, 3b) and internal (4a, 4b) folding corners and which evolve in parallel.
    [009] A collection side (7) of the loader (2) releases the two front-facing walls of the package (5a, 5b) from the respective front packaging liner (1). So that the packaging linings (1) on the collection side (7) do not fall out of the magazine, retaining elements (8a, 8b) are arranged on the collection side (7) that extend along the folding corners (3a, 3b) of the front packaging liner (1). The respective front packaging liner (1) is not removed across the entire width of the two packaging walls (5a, 5b). The packaging liner (1) is primarily captured on one of the two sides of the packaging freed (5a) from the packaging liner (1) on the collection side (7) of the magazine (2) (comp. Figure 1 a)) . To capture the wall of the package (5a), there is a suction clamp (9) which is attached to a rotating arm (11) arranged rotatably around an axis (10). Through a rotating movement of the suction clamp (9) performed around the perpendicular axis (10), the outer folding corner (3a) of the retaining element (8a) is released, forming a flat parallelogram (as shown) it can be seen mainly in Figure 1a) with the continuation of the rotating movement of the suction clamp (9) around the opposite outer folding corner (3b), which is still held by the retaining element (8b). During the continuous rotating movement, the outer folding corner (3b) of the retaining element (8b) is first released. Then, the packaging liner (1) is slidably guided with the rest of the two packaging walls (5b) released along a curved guiding surface (12) of a guide element (13). The guiding surface (12) causes the movement of the packaging liner (1) along the movement path (14) to increase the acute interior angles (15a, 15b), which include the interior angle (15a) between the packaging walls (5b, 6b) and the interior angle (15b) between the packaging walls (5a, 6a). In the direction of the movement path (14) there is at the end of the curved guide surface (12) a fixing element (16), which is placed in the form of a groove-shaped recess in the guide element (13). The fixing element (16) serves to house the outer folding corner (3b) of the unfolded packaging liner (1). Also in the direction of the movement path (14) behind the guide surface (12) there is another fixed fixing element (17) in the form of a retaining rail (17) to house the diametrically opposite outer folding corner ( 3a). The distance and alignment of the fasteners (16, 17) are made so that the packaging coating received by the fasteners (16, 17) forms a rectangular cross-section. This alignment is necessary for a perfect transition from the unfolded packaging liner to the transport device arranged after the collection and unfolding device, as above all the transport wheels initially mentioned. At the end of the curved guiding surface (12) the first acute interior angle (15a, 15b) of the packaging liner is temporarily just over 90 °, as can be seen from Figure 3 C), to ensure a perfect engagement of the folding corner (3b) on the fastener (16). The folding corners (3a, 3b, 4a, 4b), especially the inner folding corners (4a, 4b) of the packaging liner (1), cause recovery moments that react against the unfolding of the packaging liner (1). With the unfolding of the packaging liner (1) initially folded flat in a rectangular packaging liner in cross section, the recovery times are increased. As can be seen mainly in Figure 2 b), the contact line between the wall of the package (5b) slidingly guided and the guide surface (12) passes approximately in the middle of the wall of the package parallel to the folding corners (3b, 4a ) adjacent to the packaging wall (5b). Due to the increasing moments of recovery with the unfolding along the movement path (14), increasing compression forces also appear between the packaging wall (5b) and the guiding surface (12). The high compressive force increasing along the movement path requires a strong suction force from the suction gripper (9) to keep the packaging liner (1) fixed during the collection and the unfolding movement. Since filling machines require a high flow rate to fill the packaging containers, the collection and unfolding of the packaging liners must occur at a correspondingly high speed. This causes these packaging liners (1) to be pulled onto the fasteners (16, 17) at high speed along the guide surface (12), which, because of the inevitable uptake of the packaging liner in the element (16), causes a strong development of noise. In addition, both when capturing the packaging liner on the fixing element (16) and also during the unfolding movement along the guide surface (12), relatively high transverse forces arise between the suction cup suction cups (9) and the packaging wall (5a). If the clamping forces of the suction clamp are exceeded there, an unintended release of the captured packaging liner can occur and, therefore, a malfunction of the entire filling machine. In addition, the high compressive forces between the guided packaging wall and the guide can cause signs of wear on the packaging wall.
    [010] EP 0 766 621 B1 announces a device for collecting a packaging liner from a magazine and for unfolding the packaging liner to form a rectangular cross-section, in which a clamp rotatably arranged around a rotating axis captures a of the two packaging walls free of the flat folded packaging liner on the collection side of the charger. The device also has a guide rotatably arranged around an axis in the form of a door swingable from a first position to a second position by means of a drive. In addition, the device has a fixed fastener for receiving one of the two outer folding corners of the packaging liner not yet fully unfolded. The opposite folding corner is not, however, captured by a fastener. Instead, the wall of the packaging not caught by the forceps is next to the swinging door.
    [011] Thanks to the flap of the door in a clockwise direction around the axis, the packaging liner is fully assembled, so that the cross section of the packaging liner is rectangular. The wall of the package next to the swing door slides along the swing door until in the end position of the swing door a ledge arranged at the end of the door receives the second outer fold corner. The suction gripper can only be released for a rectangular cross-section after the complete alignment of the packaging liner, otherwise the recovery forces of the packaging liner would otherwise cause the device to slip out. Another advantage of the device is that in the phase with the greatest recovery forces, namely in the complete alignment of the packaging lining, the packaging lining is close to the door, exerting a relative movement towards it, which can result in greater wear and damage on the packaging wall.
    [012] From this state of the art, the invention aims to provide a filling machine of the type initially mentioned, which needs less fixing forces to collect and unfold packaging linings, which prevents malfunctions and signs of wear on the wall. guided packaging that reduces noise. The invention also aims to propose a corresponding process for collecting and capturing packaging linings from a loader of such a filling machine.
    [013] This task is solved by a filling machine according to the generic term of claim 1, valid for the fact that the guide is equipped so as to cause an increase in the interior angles to a value below 90 °, at least one of the two elements between the initial position and the final position is arranged in such a way as to move back and forth and the fastening elements are arranged so that, after the increase of the interior angles, they receive the folding corners by the guide sides of the packaging liner not yet fully unfolded, forming a parallelogram in cross section, and, with the subsequent movement of at least one of the two fixing elements between the initial position and the final position, fully unfold the packaging liner so that the cross section of the packaging liner is rectangular.
    [014] Furthermore, the task is solved by a process with the characteristics of claim 13.
    [015] Since the increase in the acute interior angle increases the recovery forces of the packaging coating, it is possible to effectively reduce the forceps of the clamp by delimiting the value of the interior angle. The guide is equipped to cause an increase in the interior angles below 90 °. The maximum increase in the interior angle can, for example, be defined by the angle between a guide guide surface and the forceps movement path, as well as the length of the guide surface.
    [016] The transition from the packaging liner of the guide to the fasteners is carried out with the same packaging liners with a reduced recovery force in relation to the state of the art, so that noise during the engagement of the fasteners is also reduced . The fastening elements are arranged so that, after increasing the interior angles, the outer folding corners of the packaging liner are not yet fully unfolded by the guide and form a parallelogram in cross section. The fastening elements may, for this purpose, be arranged in the direction of the claw movement path behind the guide or a guide guide surface.
    [017] The fixing elements for receiving the outer folding corners are preferably arranged in the direction of the forceps movement when retracting behind the guide. One of the guide elements can also be designed as a guide component at the end of a guide surface. The fastening elements are not, however, arranged on the clamp or on the transport device arranged below, as this would prolong the collection and alignment work cycle.
    [018] With the help of at least one movable fastening element between an initial position and an end position, it is possible to increase the interior angle to 90 °, so that the packaging covering takes on the final position of the fix the desired rectangular cross section and be fully unfolded.
    [019] The guide is preferably designed so that at least in one final area of the guide, where the recovery forces have already risen strongly, the outer folding corner is guided only instead of the packaging wall. Therefore, the guide and the packaging wall do not come into contact at least in the final area of the guide, thus safely preventing signs of wear on the packaging wall due to strong compressive forces in the final phase of movement along the guide. The forces resulting from the recovery moments are exclusively consumed through the guided bending corner and, therefore, the forceps of the gripper continue to be reduced.
    [020] In a constructively advantageous way, the fastening element for receiving the outer folding corners guided between a starting position and an end position is movable here and there, and the fastening element for receiving the outer folding corner diametrically opposite is fixed fixed.
    [021] Before the packaging liner forms the desired rectangular cross-section, the folding corner that goes in front of the packaging liner goes to the fixed fastener, in particular a fixed fastener in place. At the same time, the folding corner that follows from the packaging liner that forms a non-rectangular parallelogram enters the action area of the movable fastening element here and there between an initial position and an end position. This movable fastener is now moved from the start to the end position until the desired rectangular cross section of the packaging liner is achieved.
    [022] The required movement path between the initial position and the final position of the fastener (s) depends on how far the packaging liner at the end of the guide has already been unfolded, that is, the angular value of the sharp interior angles at the corners folding edges of the packaging liner at the end of the guide are less than 90 degrees.
    [023] An almost complete unfolding of the packaging lining before the fastening elements become effective, conditions a short movement path between the initial position and the final position of the fastener (s). A less complete unfolding of the packaging lining before the fasteners become effective, conditions a longer movement path between the initial position and the final position of the fastener (s). The longer movement path reduces the clamping forces of the clamp and the formation of noise, but has a negative effect on the duration of the process for unfolding the packaging liner, while the shorter movement path increases the clamping forces of the clamp. and the formation of noise, but reduces the duration of the process.
    [024] Taking into account the previous relationship, the guide mainly causes an increase in the acute interior angles to a value between 30 ° - 80 °, preferably between 45 ° - 60 °.
    [025] After the mobile fastener is in the final position or the two mobile fasteners are in the final position and the packaging liner has the desired rectangular cross-section, it is preferably transmitted, with a lifting device or the clamp itself, for a conveyor line arranged to follow, especially in the mandrel of a conveyor wheel.
    [026] A further reduction in the clamping forces can be achieved by the fact that the path of movement of the clamp is straight and runs perpendicular to the wall of the packaging freed from the packaging lining on the collection side of the loader, which the gripper captures. The movement path in such an aligned way of the clamp reduces its clamping forces, especially the suction force of the clamp preferably equipped as a suction clamp. The rectilinear guide further reduces the strain on packaging linings and wear on the suction cups of the clamp.
    [027] A continuous unfolding of the packaging liner until it forms a non-rectangular parallelogram in cross section is preferably achieved by the fact that the guide includes a flat guide surface to slide the outer packaging corner and the distance between the the guiding surface and the path of movement of the gripper on the side of the loader is continuously reduced in the direction of the fasteners to receive the outer folding corners.
    [028] A safe and protective reception of the packaging liner material in the outer folding corners is achieved by the fact that each fastening element has two angular surfaces in relation to each other, which flatly touch the packaging walls in the final position of the movable or moving fasteners here and there. The corresponding clamping forces are then introduced not only into the folding corners, but also into the border sections of the walls.
    [029] In the constructively advantageous version, each mobile fastening element is mainly constituted as an angular profile. As a drive for the movable fixing rail here and there, a linear system is used, which includes a lever with linear guide and auxiliary motor. But electromechanical linear drives can also be considered.
    [030] As long as the location combinations in the filling machine require a particularly compact construction, one of the two fastening elements on the guide can be arranged in a model of the invention. The fastening element is particularly designed as an integral component of the guide; for example, it can be designed as an entire part with the guide as a milled or casted part.
    [031] If at least one of the two fasteners is moved from the start to the end position, the guidance of the packaging liner along the guide ends. It is therefore also possible to design the movable fastening elements here and there, which are arranged on the guide together with the guide between a starting position and an ending position.
    [032] We proceed to explain the invention in detail by means of two figures. In particular:
    [033] Figure 2 shows a partial schematic perspective view of a filling machine in the area of the collection and unfolding device, during the collection of a flat folded packaging liner from a loader,
    [034] Figure 3 shows the partial view of the filling machine according to Figure 2, during the transition from the unfolded packaging liner to a conveyor wheel arranged next along the conveyor line, as well as,
    [035] Figure 3a shows a detailed view of a coating slide of a filling machine according to Figures 2 and 3,
    [036] Figures 4 a-d show a schematic view to visualize the process for collecting and unfolding packaging liners from a loader of a filling machine according to Figures 2 and 3, as well as,
    [037] Figures 5 a-e show a schematic view to visualize the process for collecting and unfolding packaging liners from a loader of a second example of a filling machine model according to the invention.
    [038] If the filling machines according to the invention partially shown in Figures 2 - 5 for filling liquid food in packaging containers include components coinciding with the filling machine represented partially in Figure 1 according to the state of the art, the same reference symbols. In addition, reference is also made to the explanations of the filling machine shown in Figure 1.
    [039] On a frame (18) of the filling machine, the loader (2) for receiving the packaging linings (1) folded in order to produce packaging containers is arranged at the beginning of the conveyor line.
    [040] The loader (2) includes fixing profiles (19a, b), which abut the outer folding corners (3a, b) of the packaging linings (1). On the front sides of the free arms of the fixing profiles (19a, b) are the retaining elements (8a, b) formed as projections. The retaining elements (8a, b) prevent the stack of vertical packaging linings (1) received by the loader (2) from falling from the loader (2) on the collection side (7).
    [041] The collection side (7) of the loader (2) releases the two front walls of the package (5a, 5b) facing the front of the total of four walls of the package (5a, b, 6a, b) of the respective covering front packaging (1). The collection and unfolding device arranged after the loader (2) on the conveyor line of the filling machine comprises a suction clamp (9) with three pneumatic suction cups to capture the packaging wall (5a) released on the collection side ( 7). The suction clamp (9) is attached to an actor (20) which is displaceable along a straight movement path (21) perpendicular to the packaging wall (5a) freed from the packaging liner (1). The displacement movement is carried out with a linear system.
    [042] The collecting and unfolding device also has a flat guiding surface (23) as a guide for the outer folding corner (3b) of the other two free packaging walls (5b) of the packaging liner. The flat guide surface (23) serves for the sliding guide of the outer folding corner (3b).
    [043] In the direction of the movement path (21) behind the flat guide surface (23) there is a fixed fastening element (17) to accommodate the outer folding corner (3a). The fixing element (24) for receiving the outer folding corner (3b) diametrically opposite can be moved back and forth between an initial position shown in Figures 4 a) - C) and an end position shown in Figure 4 d) through a linear drive. Both the fixed fastening element (17) and the movable fastening element (24) are constituted as an angular profile. The two angularly arranged surfaces of the angular profile touch the packaging walls (5a, 6a or. 5b, 6b) in the final position shown in Figure 4 d).
    [044] As can be seen mainly in Figures 4 a) - d), the distance from the flat guiding surface (23) and the movement path (21) of the suction gripper (9) on the collection side is continuously reduced (7) of the magazine (2) towards the fasteners (17, 24).
    [045] In order to transmit the packaging liner (1) fully assembled by the fasteners (17, 24) to a transport device (22) arranged after the filling and unfolding device of the filling machine, a slide is provided covering (28) which can be moved vertically up and down by means of a surrounding mat (30).
    [046] The transport device (22) includes a transport wheel (26) rotating around an axis (25) with four parallel receivers extending radially outward, which have, respectively, several profiles (27) that touch both the inner folding corner (4a) as in the packaging walls (6a, b). The profiles (27) form cells, where the unfolded packaging linings (1) with an actor's rectangular cross-section (20) can be inserted. The rotating axis (25) of the transport wheel (26) runs in a horizontal plane transverse to the transport line (21) of the filling machine. The transport wheel (26) is progressively rotated by a drive not shown by 90 degrees respectively around the rotary axis (25) of the transport wheel. From the represented transport wheel (26), the unfolded packaging liners are transmitted to other transport devices not shown in the Figures, to perform on the packaging liners (1) processing steps to produce the packaging container.
    [047] The loader (2) of the filling machine partially shown according to Figure 5 coincides with the loader (2) of the filling machine according to Figures 2 to 4, so that we refer to the explanations contained therein.
    [048] The collection side (7) of the loader (2) releases the two front walls of the package (5a, 5b) facing the front of the total of four walls of the package (5a, b, 6a, b) of the respective covering front packaging (1). The collection and unfolding device arranged after the loader (2) on the conveyor line of the filling machine comprises a suction clamp (9) with three pneumatic suction cups to capture the packaging wall (5a) released on the collection side ( 7). The suction clamp (9) is attached to an actor (20) which is displaceable along a straight movement path (21) perpendicular to the packaging wall (5a) freed from the packaging liner (1). The movement is carried out with a usual linear actuation, especially a pneumatic cylinder.
    [049] The collecting and unfolding device also has a guide surface (23) curved as a guide to the other of the two free packaging walls (5b) of the packaging liner (1). The curved guide surface (23) serves for the sliding guide first of the packaging wall (5b) (comp. Figure 5 b) and then (comp. Figure 5 C) of the outer folding corner (3b). The transition to guiding the folding corner causes at least one final section of the guiding surface (23), where the recovery forces caused by the packaging liner (1) have already risen considerably, only the outer folding corner is guided (3b) instead of the packaging wall (5b) of the packaging liner. The guide surface (23) and the packaging wall (5b) therefore do not come into contact at least in the final section, thus safely preventing signs of wear on the packaging wall (5b) due to strong compressive forces on the final phase of movement along the guiding surface (23). At the same time, the compression forces of the suction gripper (9) continue to be reduced in the critical final phase of the unfolding movement through the guide.
    [050] In the direction of the movement path (21) behind the curved guide surface (23), there is also, in this version of the invention, a fixed fastening element (17) for housing the outer folding corner (3a) ( Figure d). The fixed fixing element (17) is constituted as an angular profile. The fixing element (24) for receiving the outer folding corner (3b) diametrically opposite is found in the guide itself in this version. The fastening element (24) has two surfaces arranged reciprocally perpendicular, which as an integral component of the guide element (13) jump backwards from the curved guide surface (23) also arranged on the guide element (13). The guide element (13), which comprises the guide surface (23) and the fixation element (24), can be moved back and forth between the initial position shown in Figures 5 a) d) and the final position represented in Figure 5 e) by means of a linear drive. The two reciprocally perpendicular surfaces of the integrated fastening element (24) touch the packaging walls (5a, 6b) in the final position shown in Figure 5 e).
    [051] In order to transmit the packaging liner (1) fully assembled by the fixing elements (17, 24) to a transport device (22) arranged after the filling and unfolding device of the filling machine, it is also provided in this version a covering slide (28) that can be moved vertically up and down by means of a surrounding mat (30).
    [052] The transport device (22) is mounted according to the representation of Figures 2 to 4, in order to make reference to these versions.
    [053] The following explains in detail the process for collecting and unfolding the packaging linings (1) from the loader (2) of the filling machine, taking into account Figures 2 - 4:
    [054] Start by filling the magazine (2) with a stack of packaging linings (1) folded flat, which in the version shown are vertical. The magazine (2) releases the two front packaging walls (5a, b) on the collection side (7) of the magazine (2) to be captured by the suction gripper (9). The suction gripper (9) is moved by the actor (20) in the direction of the collection side (7) to a front position of the movement path (21) and captures the free front packaging wall (5a) with the help of the three suction cups of the suction gripper (9), as a pressure is produced in the suction cups pneumatically. Then, the suction gripper (9) is moved from the front position of the movement path (21) towards its rear position with the help of the actor (20) along the movement path (21). The outer folding corner (3a) of the retaining element (8a) begins to be released, while the outer folding corner (3b) is still retained by the retaining element (8b) on the collection side (7). The packaging liner opens in a parallelogram type, as can be seen above all from the perspective presentation according to Figure 2 and Figure 4 a). During the continuation of the movement of the packaging liner (1) along the movement path (21) with the help of the suction clamp (9), the outer folding corner (3b) of the retaining element (8 b) is also released ) and slides along the flat guide surface (23), which causes a continuous increase in the acute internal angles (15a, b) between the packaging walls (5b, 6b or 5a, 6a) to these internal angles (15a, b) in the version shown at the end of the guiding surface (23) approximately 50 ° (comp. Figure 4 c)).
    [055] At this moment, the guided outer folding corner (3b) reaches the area of action of the mobile fastening element (24), which is still in its initial position (comp. Figure 4 c)). The diametrically opposite outer folding corner (3a) is now received at the fixed fastener (17). The cross section of the packaging liner (1) received by the two fasteners (24, 17) forms a non-rectangular parallelogram.
    [056] The movable fastener (24) is now moved from the initial position (Figure 4c) to the final position shown in Figure 4d), in which the cross section of the packaging liner (1) received by the fasteners (17 , 24) forms a rectangle as soon as the movable fastener (24) has assumed the final position (comp. Figure 4d).
    [057] As soon as the mobile fastening element (24) assumes the final position represented in Figure 4 d), the two fastening elements (17, 24) are aligned with respect to a reception formed by the profiles (27) of the transportation (26). The suction cups of the suction clamp (9) are switched off.
    [058] The assembled packaging liner (1) can now be moved to the reception with the help of the liner slide (28), which captures the packaging liner (1) at its lower edge (29). As soon as the packaging liner (1) is in the reception profiles (27), the 5 suction grippers (9) go back towards the front side of the stack, towards the collection side (7) of the magazine (2 ), to capture the next packaging liner (1). Meanwhile, the liner slide (28) moves on the mat (30) downwards, to capture the next packaging liner (1) mounted on its lower edge (29) and move to the reception. 10 LIST OF REFERENCE SYMBOLS
