Definitions
- the invention generally relates to a stacking device for flat objects stacked on edge, said stacking device comprising at least one support defining a bearing plane adapted to receive said stack of flat objects in formation along a trajectory d predefined stack, a retaining pallet carried by a first slide disposed laterally with respect to the support plane and on which the retaining pallet is movable in translation along the stacking path between an upstream position and a downstream position, the pallet retainer being manually retractable between a working position in which it extends above the support plane to a first working height and interferes with the stacking path to be able to receive the support of the surface of a flat objects and a rest position in which it does not interfere with the stacking trajectory, the retaining pallet being coupled to means of braking ge arranged to oppose the movement of the pallet retaining during stacking.
- the invention also relates to a postal sorting machine comprising sorting outlets provided with stacking devices and comprising such a stacking device.
- a flat object designates in particular, but not exclusively, a postal item.
- the postal items which can be processed by the treatment plant of the invention, may have variable dimensions, but also variable mechanical characteristics, particularly as regards their rigidity. These postal items can be, among others, a simple letter, a magazine, an envelope with or without window, a newspaper, or a catalog presented in a plastic envelope or paper, with or without bellows.
- This type of stacking device is commonly used, in particular for mail sorting machine stackers.
- the postal objects constitute, as and when stacking, a stack of postal objects on edge retained by the pallet retaining associated with the braking means.
- the retaining pallet is for example carried by two rods oriented along the path of constitution of the stack and forming a first slide.
- the pile can continue in good conditions, it is necessary that the collection of the handle of postal items is done while keeping the other postal objects on edge and tight pile.
- the Operator places his left hand above the front of the stack so that his thumb is against the front face of the first postal item. the pile and his other fingers are above the pile. With his other fingers the Operator delineates the handful of postal objects to be grasped by bringing the top of the postal items concerned closer to the top of the first postal item of the pile.
- the Operator moves the retaining pallet to its rest position, it therefore no longer maintains the front of the stack, this function being provided by the hand of the Operator and in particular by the thumb.
- the stability of the stack is weakened because the maintenance of its first postal item is provided only by the thumb, only in support at the top of the first postal item.
- the Operator must then put the handle back in place before it can be placed in the transport tray. This additional manipulation is time consuming and a source of risk of poor positioning of the postal objects relative to each other, or even degradation of the postal objects. This type of stacking device is therefore not satisfactory.
- the publication EP 1 306 337 describes a stacking device comprising a braking mechanism of the retaining pallet, able to oppose the displacement of the retaining pallet during the constitution of the stack.
- This braking mechanism is coupled to an adjustable resistive mechanism adapted to vary the opposition force of the brake mechanism to the displacement of the retaining pallet.
- This stacking device also does not solve the problem raised previously.
- the object of the invention is to remedy these drawbacks by proposing a stacking device and a postal sorting machine facilitating and making reliable the removal of a handful of flat objects while effectively maintaining the rest of the stack of flat objects, in particular by preventing the bottom of the first flat object from slipping and do not ripe to the front of the pile.
- the invention relates to a stacking device for flat objects stacked on edge, comprising at least one support defining a bearing plane adapted to receive the stack of flat objects in formation along a stacking path predefined, a retaining pallet carried by a first slide disposed laterally with respect to the support plane and on which the retaining pallet is movable along the stacking path between an upstream position and a downstream position, and manually retractable between a position in which it extends above the support plane to a first working height and interferes with the stacking path to be able to receive support from the surface of a flat object and a position of rest in which it does not interfere with the stacking path, the retaining pallet being coupled to braking means arranged to oppose the movement of the retaining pallet during the emp ilage, characterized in that it comprises at least one holding finger adapted to be in an extended position in which it extends above the support plane to a second working height less than the first height of work and interferes with the stacking trajectory for receiving the support of the foot of a flat
- the idea behind the invention is to provide, on the same side of the support as the pallet, a holding finger independent of the pallet retaining and whose contact with the flat objects is limited, by its height of work less than that of the pallet, at the foot of each first flat object.
- the holding finger retains the foot of the first flat object by preventing it from shifting forward, even when the pallet is moved backwards so as to release a handful of flat objects to grasp, while leaving accessible top of flat objects to allow their grip.
- the support is formed by two conveyor belts parallel to each other and spaced from each other so as to provide between them an access zone adapted to receive the passage of a hand of an operator to access from below the plan of support for flat objects. A handful of flat objects can thus be grasped simultaneously from below and from above;
- the stacking device comprises at least one drive belt provided under the support plane between the conveyor belts and coupled in displacement to the conveyor belts, the retaining pallet comprises an extension arranged for, in the working position of the retainer pallet, cross the support plane and bear against the drive belt so that the retainer pallet is coupled in motion to the drive belt;
- At least one retaining finger and retaining pallet comprises an abutment arranged to respectively abut against the retaining pallet, the retaining finger, and prevent movement of the retaining finger upstream of the retaining pallet according to the stacking trajectory;
- the first slide and the second slide are provided in a guide plane perpendicular to the support plane;
- the holding finger is arranged to, in a retracted position provided beyond the front position, be further retractable from the extended position to an input position in which it does not interfere with the stacking path;
- the stacking device may comprise at least one jogging edge capable of laterally guiding the flat objects along the stacking path, the one jogging edge including at least one groove defining the second slide;
- the groove comprises at least one lateral notch adapted to receive the retaining finger in its entered position and defining the retracted position, the retaining finger being arranged to pivot with respect to an axis substantially parallel to the stacking trajectory between its exit and retracted positions;
- the return means comprise at least one of the elements selected from the group comprising at least one elastic return element, a counterweight.
- the invention also relates to a postal sorting machine comprising sorting outlets provided with at least one stacking device as previously described.
- Figures 1 to 5 are perspective views of the stacking device according to a first embodiment of the invention with the retaining finger and the retaining pallet in different positions successive;
- Figure 6 is a side view of the stacking device of Figures 1 to 5 empty (not containing flat object);
- Figure 7 is a perspective view of the stacking device according to a second embodiment of the invention, in a vacuum and in an intermediate position of the retaining pallet and the retaining finger.
- elements similar to those of Figures 1 to 6 are assigned the same reference numbers, increased by 100;
- Figure 8 is a perspective view of detail of the stacking device of Figure 7 illustrating in particular the interfering stop between the retaining pallet and the retaining finger.
- the piling device for flat objects stacked on edge according to the invention is for example placed at a sorting outlet of a postal sorting machine (not shown). This specific application is however not limiting.
- the stacking device 1 for flat objects 2 stacked on edge comprises a frame 3, a support 4 flat objects 2, a jogging edge 34, a retaining pallet 6 and a retaining finger 7.
- the support 4 is formed by two conveyor belts 40 carried by pulleys 41 rotatable relative to the frame 3, only part of which is shown.
- the conveyor belts 40 are arranged substantially parallel to each other so that the axes of their pulleys 41 are substantially coaxial and their upper strands define coplanar support zones spaced apart and defining a bearing plane P adapted to receive stack of flat objects 2 on vocals.
- the conveyor belts 40 define between them an access zone 42 capable of receiving the passage of a hand of a Operator to access from below flat objects 2 resting on the support plane P.
- the pulleys 41 are either crazy or motorized.
- the pulleys 41 and conveyor belts 40 allow the stack of flat objects 2 to be advanced during stacking, on the support plane P, according to a predefined stacking trajectory symbolized in the figures by the arrow E.
- the latter can for example be made of a rough material.
- the support may be formed by any other suitable element.
- the frame 3 comprises a lateral wall offset on the side of the support plane P and having a cutout so as to form a downstream upright 30 and an upstream upright 31 between which are fixed two rods 32 smooth, substantially parallel to each other and relative to the stacking path E.
- These rods 32 are superimposed on each other in a guide plane G substantially perpendicular to the support plane P.
- the rods 32 are located above the support plane P, therefore on the same side as that intended to receive the flat objects 2.
- These rods 32 define a first slide 33 relative to which slides an arm 64 carrying the pallet retaining 6.
- the arm 64 is formed of a parallelepiped traversed by two orifices adapted to receive the sliding passage of the rods 32.
- the upper part of the arm 64 forms a stirrup between the branches of which is received a pivoting axis 60 of the retaining pallet 6.
- the retaining pallet 6 is in the form of a plate provided with a lever 61 connected to the pivoting axis 60.
- the plate extends in a plane substantially perpendicular to the stacking path E.
- the retaining pallet 6 has a trapezoidal shape. This form is not meant to be limiting. It can be traversed by a hole 62 provided to the lever 61 and facilitating its handling.

- the holding pallet 6 extends above the support plane P to a first working height H1 (illustrated in Figure 1).
- the working height H1 of the retaining pallet 6 being greater than the height of the flat objects 2, the retaining pallet 6 extends above the top of the flat objects 2 when in its rest position. Thus, in its rest position, the retaining pallet 6 does not hinder the movement of the flat objects 2.
- the retaining pallet 6 is also movable along the stacking path E between an upstream position in which it can be placed in or at the rear of the pile of flat objects 2, and a downstream position in which it is placed at the front of the pile of flat objects 2.
- the pallet of retaining 6 is also coupled to braking means, for example a spring 65 as shown in Figure 5, able to oppose the displacement of the retaining pallet 6, at least during its displacement from its upstream position to its downstream position
- braking means for example a spring 65 as shown in Figure 5
- the retaining pallet 6 thus holds the flat objects 2 stacked behind it on edge.
- the part of the frame 3 connecting the downstream upright 30 and the upstream upright 31 forms a jogging edge 34 adapted to provide lateral guidance of the flat objects 2 stacked on the conveyor belts 40.
- This jogging edge 34 is hollowed out with a groove 35. extending substantially parallel to the stacking path E and defining a second slideway 36 relative to which slides the holding finger 7.
- the second slideway 36 is thus parallel to the first slideway 33.
- the holding finger 7 has the shape general of a T whose branches 70 (visible in Figure 6) are housed in the groove 35.
- the second slideway 36 is adapted to guide the holding finger 7 according to the stacking path E.
- the downstream end groove 35 is extended laterally by a lateral notch 37 allowing tilting of the holding finger 7 between its extended position in which the rod 71 of the T is prominent of the jogging edge 34 so as to interfere with the stacking path E and an input position in which the rod 71 of the T is retracted into the lateral notch 37 and does not interfere with the stacking path E.
- the second slideway 36 is placed under the first slideway 33 in the guide plane G.
- the holding finger 7 When in its extended position, the holding finger 7 extends above said support plane P on a second working height H2 (shown in Figure 1) less than the first working height H1.
- H2 shown in Figure 1
- the holding finger 7 can receive the support of the flat objects 2 placed behind it, this support being limited to the foot of the flat objects 2.
- the holding finger 7 When the retaining pallet 6 is in its working position, the holding finger 7 is pressed in front of the retaining pallet 6.
- the holding finger 7 is coupled to return means 8 (visible in Figure 6) tending to oppose its movement.
- the holding finger 7 prevents slipping forward of the foot of the first flat object 2 placed behind the holding finger 7 and subsequent flat objects 2.
- these return means comprise a traction spring 8, one end of which is secured to the holding finger 7 and the other end of which is integral with the frame 3.
- the return means can be of any other type, for example example a counterweight connected to the holding finger by a flexible link.
- the holding finger 7 Via the second slideway 36, the holding finger 7 is also movable along the stacking trajectory E between a rear position (illustrated in FIG. 1) in which it can be placed substantially in the same plane as the retainer pallet 6 when in its upstream position, and a front position (illustrated in FIGS. 2, 3 and 4) in which it is placed at the front of the pile of flat objects 2 and at the front of the 6.
- the holding finger 7 has a height allowing it when in its extended position, cross the trajectory of the pallet retaining 6 when the one it is in its rest position !.
- the trajectory of the retaining finger 7 in its extended position coincides with part of the trajectory of the retaining pallet 6.
- the retaining finger 7 in the extended position remains permanently downstream of the retaining pallet 6 in the working position, eliminating the risk of stacking flat objects 2 between the retaining pallet 6 and the retaining pallet 6. retaining finger 7.
- the holding finger 7 is movable, beyond the front position, to the retracted position defined by the lateral notch 37 of the groove 35.
- the holding finger 7 comprises resilient tilting means tending to tilt in the lateral notch 37.
- the holding finger 7 and the retaining pallet 6 are permanently above the support plane P and thus remain accessible by the operator, regardless of their position.
- the difference in working heights H1, H2 between the retaining pallet 6 and the retaining finger 7 makes it possible on the one hand for the retaining pallet 6 to be fully operational in its working position even in the absence of the retaining finger. 7 (in its entered position) to hold the flat objects 2 over their entire height, on the other hand to the finger of maintaining 7 to effectively retain the foot of the flat objects 2 while leaving free access to the top of the flat objects 2 and thus facilitate their manual gripping by the operator.
- the stacking device 101 according to a second embodiment of the invention and illustrated by FIGS. 7 and 8, is substantially similar to the previous one.
- the support 104 carried by the frame 103, comprises two conveyor belts 140 separated by an access zone 142 in which is housed a drive belt 180.
- This drive belt 180 is notched and arranged parallel to the conveyor belts 140, shifted under the support plane P.
- the drive belt 180 is coupled in displacement, by any known means, to the conveyor belts 140 so that they advance at the same time.
- the retaining pallet 106 is guided by the first slide 133 and the retaining finger 107 is guided by the second slide 136.
- the retaining pallet 106 has an extension 166 extending it.
- the extension 166 passes through the support plane P and is housed between two notches of the drive belt 180. The movements of the retaining pallet 106 and of the drive belt 180 are thus linked.
- the retaining pallet 106 is provided with a stop 167 (visible in FIG. 8) extending under the arm 164 and interfering with the trajectory of the retaining finger 107 at the level of the second slide 136.
- the abutment 167 prevents the retaining finger 107 to pass upstream of the retaining pallet 106 with respect to the stacking direction E.
- the retaining finger 107 is blocked before its upstream surface is in contact with the downstream surface of the pallet
- the blocking by the stop 167 is effective regardless of the position of the retaining finger 107 (entered position, extended position) and that of the retaining pallet 106 (working position, rest position).
- the use of the stacking device 1, 101 is described below, without limitation with reference to the stacking device 1 of the first embodiment.
- the stacking device 101 according to the second embodiment is used in a similar manner.
- the retaining pallet 6 in a first configuration before use, the retaining pallet 6 is respectively in its rest position and in its upstream position and the holding finger 7 is respectively in its extended position and in its rear position.
- the holding pallet 6 is tilted from its rest position to its working position in which it interferes with the stacking trajectory E of the flat objects 2.
- the holding finger 7 is then plated in front of the retaining pallet 6.
- the stack of flat objects 2 is primed at the rear of the retaining pallet 6.
- the retaining pallet 6 is respectively in its working position and in an intermediate position in which it has advanced with respect to its upstream position, pushed by the face of the flat objects 2 which pile up behind her.
- the forward movement of the retaining pallet 6 is braked by the braking means (spring 65 of FIG. 6).
- the holding finger 7 is respectively in its extended position and in an intermediate position in which it has advanced with respect to its rear position, pushed by the retaining pallet 6 in front of which it is plated and the foot of the objects plates 2 which stack behind the retaining pallet 6.
- the forward movement of the retaining finger 7 is braked by the return means 8.
- the retaining pallet 6 and the retaining finger 7 advance progressively as and as the constitution of the pile of flat objects 2 at the rear of the retaining pallet 6.
- the stack is stable during stacking.
- the stack has increased, the retaining pallet 6 and the holding finger 7 which followed the progression of the stack are respectively in their downstream and forward positions. It is time for the Operator to grab a handle 20 of flat objects 2 to transfer this handle 20 for example to a storage bin (not shown).
- the Operator places his left hand above the front of the stack so that his thumb is against the front face of the first flat object 2 of the stack (and therefore of the handle 20 and his other fingers above the stack With the end of its other fingers, the operator defines the handle 20 of flat objects 2 to be grasped by moving the top of the flat objects 2 concerned from the top of the first flat object 2 of the stack .
- a fourth configuration illustrated in FIG. 2 once the flat object handle delimited by the fingers of the operator's left hand, the retaining pallet 6 is retracted by means of the right hand, by tilting around the pivoting axis 60 from its working position to its rest position.
- the retaining pallet 6 no longer interferes with the stacking trajectory E and therefore no longer maintains the front of the stack of flat objects 2 which is held by the Operator's hand and the finger 7, still in its extended position, which holds the foot of the first flat object 2 of the stack.
- the stack is stable and will not slide or rip forward while leaving the top of flat objects accessible 2.
- the Operator While holding the top of the stack, the Operator then moves the retainer pallet 6 from its downstream position to an intermediate position (between its upstream position and its downstream position) in which the retainer pallet 6 can be inserted between the handle 20 delimited by the Operator and the rest of the stack 21.
- the fifth configuration shown in FIG. 3 is thus obtained and in which the retaining pallet 6 is respectively in an intermediate position and in its working position, and the holding finger 7 is respectively in its extended position and in an intermediate position. (between its rear position and its front position).
- the holding finger 7 always retains the foot of the first flat object 2 of the handle 20, advancing progressively to follow the stack that can continue behind the retaining pallet 6 and the retaining pallet 6 retains the rest of the pile 21.
- the operator who still has his left hand above the handle 20 of flat objects 2, introduces his right hand between the two conveyor belts 40, under the flat objects 2 of the handle 20 and then bring the handle 20 forward.
- the holding finger 7 always advances the first flat object 2 of the handle 20 and is moved to its forward position.
- the operator discharges the handle 20 of flat objects 2, leaving in a fifth configuration illustrated in Figure 5, the rest of the stack 21 to form at the rear of the pallet retaining 6.
- the holding finger 7 does not should not be used for subsequent stacking, it can be retracted as shown.
- the operator can move the holding finger 7 to its intended retracted position beyond the front position, so that the holding finger 7 is facing the lateral notch 37 to be able to to be tilted in and to be in its entered position, retracted into the jogging edge 34 so as not to interfere with the stacking path E.
- the holding finger 7 remains locked in the lateral notch 37 by means 8 which removes the plate against the wall of the lateral notch 37.
- the holding finger 7 can be released at any time and tilted from its entered position to its extended position. Depending on the progress of the stack or the absence of flat objects 2 on the conveyor belts 40, it will then be brought back by the return means 8 from its retracted position to its rear position or any other intermediate position.
- the operator may also choose to leave the holding finger 7 in its extended position. In this case, it will evacuate the handle 20 of flat objects 2 without bringing the holding finger 7 to its retracted position. It is understood that the use of left and right hands can be reversed.
- the retaining pallet 6, the retaining finger 7 and the shim 34 may be arranged symmetrically with respect to the median axis separating the two conveyor belts 40.
- the holding finger 7 and said retaining pallet 6 are independent in movement from one another, which allows the holding finger 7 to continue to hold the foot of the first flat object 2 of the handle 20 of flat objects 2 while the retaining pallet 6 is retracted to be moved from its downstream position to an intermediate position towards the rear to optionally retain the rest of the stack 21.
- the foot of the front of the stack of flat objects 2 is permanently maintained effectively, the foot of the first flat object 2 and subsequent flat objects 2 not at risk of shifting nor slide to the front of the stack.
