Definitions

  • the present invention relates to a unitary dispensing device for stacked thin objects such as letters or the like.
  • Such a device also called unstacking device, comprises unstacking means such as a vacuum drum to communicate an acceleration to an object at the head of the stack and present it to a conveying device which routes it to a treatment station. , sorting or whatever.
  • unstacking means such as a vacuum drum to communicate an acceleration to an object at the head of the stack and present it to a conveying device which routes it to a treatment station. , sorting or whatever.
  • Such a distribution device is notably described in document FR-A-2 181 523.
  • a destacking device must have the highest possible flow rate, but this objective encounters many difficulties because the dimensions, the weight and the materials of thin objects are not homogeneous and can, within a stack, vary within some forks.
  • the invention aims to provide a unitary distribution device for stacked thin objects which makes it possible to obtain a flow rate of objects substantially higher than that of the devices of the prior art while offering very high availability and requiring only a number very few operators to ensure proper operation.
  • the subject of the invention is a device for the unitary distribution of stacked thin objects, comprising unstacking means for communicating an acceleration to an object at the head of the pile, characterized in that it comprises means for measuring the instantaneous speed of said object at the head of the stack during its ejection from the device by said unstacking means and means for controlling the drive of the next object by said unstacking means as a function of the speed data of said object at the head of the stack provided by said measuring means.
  • Measuring the speed of thin objects during their ejection from the unstacking device makes it possible to predict their movement and thus to control the unstacking of the next object before the object being unstacked has left the unstacking device. Thanks to this possibility of anticipating on the unstacking command of the next object, the spacing between objects can be significantly reduced and the flow increased.
  • said measurement means comprise at least one continuous speed measurement sensor comprising, for example, a rotary contact measurement probe, arranged upstream of said unstacking means.
  • said probe comprises a low inertia caster comprising an elastic bandage with a high coefficient of friction.
  • This bandage absorbs the unevenness of relief on the surface of thin objects and ensures rolling without sliding so that the speed of rotation of the wheel is a faithful image of the instantaneous linear speed of the object being unstacking.
  • the speed information of the objects can be provided by a tachometric generator integral in rotation with the caster.
  • control means are adapted to detect a decrease in the speed measured following the passage of the rear edge of an object being unstacked in front of said measurement means and to control the drive. of the next object within a predetermined period of time as from said speed reduction detection.
  • the detection of the rear edge of an object takes place while it is still being unstacked, and not at the outlet of the distribution device, which makes it possible to control the unstacking of the next object in advance while being assured of the correct course unstacking in progress thanks to the speed measurement made between setting the object in motion and detecting its rear edge.
  • a supply device 1 conveys a stack of thin objects 2, such as letters, to a unitary distribution or unstacking device 3 which extracts them one by one from the stack to present them to an output conveyor 4, which routes to a storage, processing or other station (not shown).
  • the feeding device 1 comprises a conveyor 5 with belts moved in the direction indicated by the arrow 6 by an electric motor 7.
  • the plies 2 arrive in a buffer zone 8 where they are pushed against a roller 9 driven in rotation by an electric motor 10.
  • the rotation of the roller 9 has the effect of driving upwards the objects 2 which are in abutment against it and of bringing them into a third zone 11 in which they rest in the state uncompressed on a step (not shown).
  • the supply device 1 is described in more detail in French patent application No. 92 07801 filed on June 25, 1992 to which reference may be made.
  • the feed device 1 has a side wall 12, hereinafter referred to as a jogging edge, consisting of a sheet or the like with a low coefficient of friction arranged vertically in the direction of the arrow 6 and stopping at a distance from a wall 13 constituting the bearing face of the unstacking device 3.
  • the walls 12 and 13 thus form between them a slot 14 through which the thin objects are transferred from the head of the stack to the outlet conveyor 4.
  • the objects 2 stacked on the conveyor 5 are in principle supported by their front edge against the jogging edge 12.
  • the unstacking device 3 conventionally comprises a perforated drum 15 rotatably mounted around a cylindrical part 16 in which is formed a chamber 17 communicating, on the one hand with a suction nozzle 18, on the other hand with a source depression 19 with interposition of a control solenoid valve 20.
  • the nozzle 18 has the form of a slot opening out through an opening centered on a radial plane in line with a window 21 formed in the support wall 13 and through which the drum 15 projects slightly.
  • the drum 15 when the drum 15 rotates in the direction indicated by the arrow 22 and that a vacuum is applied to the nozzle 18 under the control of the solenoid valve 20, a thin object resting against the wall 13 is pressed against the surface of the drum moving past the nozzle 18 and driven through the slot 14 towards the conveyor
  • the drum 15 is arranged as close as possible to the outlet 14 of the unstacking device so as to be able to bring the objects 2 of the minimum admissible size at a nominal speed as high as possible, in order to maximize the flow of the assembly 1, 3 and 4.
  • the wall 13 forms one of the faces of a suction box 23 connected to a vacuum source 24.
  • the suction box 13 Immediately upstream of the drum 15 relative to the direction of ejection of the objects 2, the suction box 13 houses a vacuum re-pressing drum 25 as well as a speed sensor 26 mounted behind a perforated pallet 27 capable of making small displacements relative to the wall 13 and resiliently urged projecting relative thereto by means of a member fixing 28 such as a strain gauge as described in the French patent application No. 92 07801 cited above.
  • the jogging drum and the speed sensor 26 have been shown side by side in the diagrammatic view of FIG. 1.
  • the jogging drum 25 is preferably mounted substantially above the sensor. speed as shown in Figure 2.
  • the movable perforated pallet 27 is arranged below a perforated area 29 of the support wall 13 and in this area 29 is formed an elongated vertical window 30 in which scrolls through the perforated wall of the tracker drum 25.
  • the jogging drum 25 is preferably of the type described in French patent application FR-A-2 657 856 to which reference may be made for a more detailed description. According to the teaching of this document, the wall of the drum 25 is perforated in a limited angular sector of its circumference and a depression is permanently applied to an inner nozzle located to the right of the window 30 through which the perforated part of the drum comes to slightly protrude when the latter is rotated.
  • the jogging drum 25 is capable of being driven in rotation from the drum 15 by means of a clutch 31 connected, on the one hand to the jogging drum 25 by a belt 32, on the other hand to the drum 15 by a belt 33
  • the clutch 31 is for example of the electromagnetic type.
  • the pallet 27 is pierced with a horizontal light 34 through which, as shown in FIG. 3, projects a wheel 35 constituting the feeler of the speed sensor 26.
  • This wheel 35 is preferably a very light rim surrounded by an elastic peripheral bandage with a high coefficient of friction allowing strong adhesion to thin objects 2 and the absorption of reliefs of the order of, for example, 1 mm.
  • the caster 35 is integral in rotation with a vertical axis 36 rotatably mounted between the yoke-like ends of an oscillating arm 37, by means of rolling bearings 38.
  • the axle 36 is integral at its lower end with a suspended miniature tachometer 39, the housing of which is fixed to a lug 40 extending vertically downward from the arm 37.
  • the oscillating arm 37 is articulated in an intermediate part of its length around a vertical axis 41 carried by a fixed support 42 and the end of the arm 37 opposite to that carrying the caster 35 is fixed to a spring 43 tending to urge the caster 35 projecting through the light 34.
  • a friction shoe (not shown) is provided on the axis 36 to ensure a static friction torque and allow a defined speed drop of the caster 35 when the latter is no longer in contact with a thin object 2.
  • the roller 35, and therefore the sensor 26, must be placed close enough to the outlet 14 of the unstacking device 3 so that an object of length admissible minimum reaches its nominal speed before its rear edge leaves the caster.
  • the caster must be far enough from the outlet 14 so that the detection of the rear edge of the objects 2 by the sensor 26 (by detection of a drop in the speed of the caster 35 as will be explained below) has place with an advance which is sufficient to predict the movement of the object being unstacked and generate, before it actually leaves the unstacking device, the unstacking command for the next object, in order to overcome the various delays which intervene between the unstacking command and the setting in motion of an object.
  • the position of the sensor 26 is therefore a compromise depending on the operating parameters imposed.
  • a shoe 44 Located downstream of the outlet slot 14 and upstream of the outlet conveyor 4 are provided, on either side of the path for transporting thin objects, a shoe 44 having at least one surface with a high coefficient of friction, stressed elastically against a wedge-shaped fixed shoe 45.
  • the fixed shoe 45 has, facing the shoe 44, a surface with a low coefficient of friction situated substantially in the extension of the wall 13 and substantially matches the curvature of the drum 15 on one of its sides.
  • the shoe 44 is adapted to be pushed elastically from the side opposite to the shoe 45 by the front edge of a thin object when the latter is being ejected by the unstacking drum 15.
  • the role of the shoe 44 and shoe 45 device is to promote the separation between the object at the head of the pile and the next object during an unstacking sequence.
  • Such a device is described in detail in French patent application FR-A-2 523 099 to which reference may be made.
  • the shoe 45 carries a photoelectric cell 46 which has the function of detecting, at the outlet of the unstacking device 3, the passage of the front edge and the rear edge of an object being unstacked.
  • the outlet conveyor 4 comprises a first section made up of perforated belts 47 and 48 having substantially parallel or slightly divergent strands on a first section extending from the outlet 14 of the unstacking device 3, while in a second downstream section the strand of the belt 48 diverges appreciably from the rectilinear strand of the belt 47.
  • the rectilinear strand of the belt 47 passes in front of suction boxes designated as a whole by the reference 49, while, in the second section, the divergent strand of the belt 48 passes in front of suction boxes 50.
  • a V-shaped deflector 51 is arranged downstream of the point of divergence of the strands opposite the belts 47 and 48 and makes it possible to guide thin objects, from one side towards a second section of the output conveyor consisting of belts 52 and 53, on the other side towards a recycling station (not shown).
  • the drum 15 and the perforated belts 47 and 48 are rotated from a common electric motor 54 via drive belts 55, 56 and 57 respectively.
  • the motor 54 is coupled to a tachometer generator 58 making it possible to measure and control very precisely the speeds of the drum 15 and of the belts 47 and 48.
  • the peripheral speed of the drum 15 is a few percent less than the speed of belts 47 and 48.
  • the reference 60 designates a programmable automaton making it possible to selectively control the application of a vacuum to the drum 15 and driving the jogging drum 25 as a function of programmed parameters and of the information supplied by the speed sensor 26 and the cell 46.
  • the block 61 designates an interface between the sensors and actuators and the automaton 60.
  • the block 68 is a supervision unit controlled by the automaton 60 to indicate to an operator the abnormal operating states of the unstacking device 3.
  • Inputs D C and M V respectively control the piecemeal operation of the unstacking device and its idling.
  • Block 61 is an interface between the automaton 60 and the sensors and actuators of the unstacking device 1.
  • the interface 61 receives the output signal S46 from cell 46 which, after filtering and formatting at 62 and 63, forms a signal logic E46 taking logic state 1 or 0 depending on whether or not a thin object is in front of the cell.
  • the window comparator 66 compares the speed measured by the wheel 35 with threshold values ⁇ min and ⁇ max functions of the speed of rotation communicated to the drum 15 by the motor 54.
  • the window comparator produces a first logic signal E ⁇ min which is at level 0 when the measured speed of the caster 35 is less than the threshold ⁇ min and at level 1 otherwise, and a second logic signal E ⁇ max which takes the value 0 when the measured speed of the caster 35 is less than threshold ⁇ max and value 1 otherwise.
  • FIG. 5A shows the unstacking device while a thin object 2 A is being ejected by the unstacking drum 15.
  • the next object 2 B of the stack is during plating against the pallet 27 under the effect of the suction force which is exerted in the box 23.
  • the sensor wheel 26 is immobilized in rotation by its contact with the object 2 B which pushes it gradually towards the inside of the box as the object 2 B is pressed against the support wall 13.
  • the object 2 B is in the initial unstacking position, that is to say it is pressed against the support wall 13 under the effect of the suction prevailing in the box 23 and that it thus pushes the pallet 27 and the sensor wheel 26 in the plane of the wall 13.
  • the front edge of the object 2 B is in the jogging position, namely in the plane of the edge 12 and close immediately from skate 44.
  • the sensor 26 continuously measures the speed of the object and provides this information to the automaton 60.
  • the edge rear of the object 2 B escapes from the wheel 35 of the speed sensor 26, the speed of rotation of the latter suddenly decreases due to its low inertia and, possibly, of the friction pad provided on its axis 36.
  • the treatment carried out in 64, 65 and 66 the passage of the rear edge of the object 2 B at the level of the sensor 26 is detected when the speed measured by the sensor 26 drops below the set value ⁇ max .
  • This detection makes it possible to launch by anticipation, within a determined period, the unstacking of the next object as will be explained with reference to FIG. 6.
  • the speed sensor must be placed close enough to the shore 12 so that, in the normal operating conditions and for objects having the minimum admissible length, the speed of the caster 35 reaches the value ⁇ max before the rear edge of the object comes before the speed sensor.
  • the object 2 B is being removed from the unstacking device 3 at the nominal speed fixed by the motor 54 and a new object 2 C is in position for its unstacking.
  • FIG. 5E shows an object 2 M being unstacked while the next object 2 N pressing against the wall 13 has a jogging defect: its front edge is substantially distant from the jogging edge 12 and no part of the object 2 N is not located to the right of the nozzle 18 so that in the next unstacking sequence object 2 N will not be driven by the unstacking drum 15.
  • This defect is detected by the fact that after the 'sending to the solenoid valve 20 of an unstacking control slot, the caster 35 of the sensor 26 does not reach the set value ⁇ min within a predetermined period. Consequently, the automaton 60 controls the tightening of the clutch 31 so as to cause a rotation of one revolution of the jogging drum 25.
  • the latter the surface of which is perforated over a given angular sector, thus causes a controlled displacement of the object 2 N over a length measured by the speed sensor 26, a length which is, for example at most 30 mm.
  • the retacking process is repeated until the object is sufficiently advanced (FIG. 5F) to be then driven by the drum 15.
  • the supervision unit 68 associated with the automaton 60 generates a re-tapping fault message.
  • FIG. 6 illustrates different states P1 to P6 of the automaton 60 for different positions of an object 2, positions which are identified with respect to the device unstacking 3 (whose jogging drum 25 has not been shown for clarity).
  • the object 2 is ready to be unstacked, its front edge being assumed to be in or in the vicinity of the plane of the jogging edge 12.
  • the cell 46 does not detect any object and the roller 35 is immobilized.
  • the signals E46, E ⁇ min and E ⁇ max are therefore in logic state 0.
  • the automaton 60 starts a timer T1 which is a function, in particular , nominal pitch P N and delays R t and t r .
  • FIG. 7 shows the evolution of the speed of the caster 35 from the instant t0 of application of a control slot C D to the solenoid valve 20.
  • R t represents a pure delay corresponding to the time which separates the instant of application of the control slot at the solenoid valve 20 from that of the effective establishment of the vacuum in the nozzle 18;
  • t r represents the delay which separates the instant of effective establishment of the vacuum in the nozzle 18 from the instant of effective entrainment of an object 2 by the drum 15.
  • the time delay T1 of state P1 represents the time within which the unstacking command of the object 2 must intervene after the trailing edge of the previous object has been detected by the speed sensor 26. If the unstacking command C D does not intervene before the end of the timer T1, the supervision unit 68 emits a malfunction signal.
  • the front edge of the object 2 is detected by the cell 46 and the signal E46 goes from level 0 to level 1.
  • the detection of the front edge must take place within a time T2 as a function of the delay R t and the time required for the leading edge of an object of maximum permissible weight to move from position P1 to position P2. If the leading edge is not detected within the time T2, the supervision unit 68 emits a malfunction signal.
  • the automaton controls, within an appropriate period, the unstacking of the next object in anticipation of the subsequent movement of the object 2 in unstacking course.
  • the state P6 corresponds to the detection by the cell 46 of the rear edge of the object 2 during unstacking. This detection causes the return of the signal E46 from level 1 to level 0, after the signal E ⁇ min has passed from level 1 to level 0 between the states P5 and P6. Detection of the rear edge of the object unstacked by the cell 46 must intervene within a maximum delay T6 from the instant t o .
  • the unstacking device which has just been described makes it possible to ensure a throughput of twenty letters per second at a speed of five meters per second for letters of length between 125 and 265 mm with an average length 200 mm. Thanks to the prediction of the movement of objects during unstacking and to the advance control of unstacking of the next object which allows the device according to the invention to ensure, the spacing between consecutive objects can be reduced to 50 mm, or a temporal spacing of 7 milliseconds against 35 milliseconds for the device of the state of the art which is mentioned at the beginning of this description.
