Definitions
- the invention relates to a destacker for flat objects such as mail folds.
- a postal ply sorting machine supply assembly essentially comprises a supply magazine acting as a buffer stock and as a unit for presentation to a speeding member and intended to speed up unitarily (the one after the other) each fold, finally a conveying device intended to convey the folds individually.
- the distribution devices making it possible to take one by one and in the order in which they appear the objects of a stack or of a row to send them at constant pitch (as opposed to constant spacing systems) for example in an installation processing only work satisfactorily if the position of the objects at the time of unstacking is determined very precisely.
- FIGS. 1 to 7 schematically represent the various means used in a destacker according to the invention.
- FIGS 8, 9 and 10 schematically represent other operating faults that these means make it possible to avoid.
- FIG. 1 schematically represents the position which has been found to be optimal and which the feet of the objects to be unstacked must take before reaching the unstacking face 2 of a speed-setting member (not shown). They must remain inclined at an angle Or which, for each determined application, must be kept constant until the fold concerned is caught up by the speed setting member.
- a means 3 capable of ensuring this inclination of the letters prior to unstacking can consist of a set of motorized belts 33 which follows the drive path of the letters a food store located downstream (not shown in the figure) and which may be of the type described in French patent application 2,382,387.
- the sets of letters are inserted between the pusher members driven in displacement as far as the unstacking member, where they are then retracted.
- FIG. 3 such a pusher member is shown in 5 just before its retraction.
- the positioning of the letter feet as defined by means of FIG. 1 is improved, using a blowing system 4 placed at the rear of the letter foot placed immediately after the zone d action of the last pusher member 5.
- the arrows show the direction of blowing.
- this same result can also be obtained by means of a pusher member 5 provided with tilting means making it possible to tilt it according to the angle ⁇ defined previously in the vicinity of the unstacking face 2.
- a photoelectric cell CI is placed in position to detect the presence of the foot 9 of a letter, for example on motorized belts.
- a new problem arises at this stage of unstacking namely; the separation of the letter 8 supported by the unstacking face 2 and the letter 7 which immediately follows it. This separation is ensured by the suction of the letter 8 against the unstacking face through the orifices 12, and accentuated by means of a blowing ramp 6 placed above the packet of letters brought to the speed setting member. This is a means of selecting the letter 8 pressed against the unstacking face 2 before it is speeded up in view of his training.
- Such a speed setting member is schematically represented in FIG. 6. It essentially comprises the unstacking face 2 proper comprising suction orifices 12 cooperating with a speed setting drum II. According to the invention, a detection means C2 is placed as close as possible to the speed-setting drum 11. The function of the detection means will be explained in the following description.
- the thickness of the letter to be speeded up can be entered before precisely this setting in vitese.
- an image capture head 14 is placed as shown in Figure 7 on the path of the upper part of the letter so as to determine the thickness. The information collected then leads to an adjustment of the training parameters.
- an operator fills the spaces between the pusher organs of the food store with letters.
- the store is started.
- the detection means CI gives positive information.
- the store is stopped and the set of motorized belts 33 is, or is started, as well as possibly the first blowing means 4.
- the pusher pushing the pile of ready letters to be unstacked and detected by the detection means C1 can also be put in a tilted back position. This is the instant To.
- the store is then stopped until the separation and aspiration of the folds by the speed-setting member leads the cell C1 to no longer be obscured.
- the letter is therefore in an inclined position, it is not pressed (pressed) by the feed magazine against the unstacking face.
- To + Tl the starting of the vacuum box acting on the suction orifices 12 is started; this has the effect of pressing the first letter appearing at the unstacking against the unstacking face 2.
- the second detection means C2 detects the plating of this first letter of the pile of letters which presents itself. It's time To + Tx.
- the second upper blowing means 6 are then started at time To + T2. They have, as has been said previously, the function of allowing the plating on the unstacking face only of the single letter which must be put in speed. This instant may or may not coincide with the time To + Tx.
- Regulatory actions can therefore relate to the level and frequency of pulsations of the upper air jets, the timing of the commissioning of the general letter supply and the speed of rotation of the conveyor belt of the letter feet against the unstacking face, the intensity of the depression of the speeding drum.
- a destacker according to the invention thanks to the combination of means which characterizes it leads to maximum output at a determined rate. It makes it possible to reduce the double setting rate and even makes it tend towards zero, which is a fundamental constraint for this type of application. By limiting desynchronization, it dispenses with the use of an additional device at the entrance to the machine.
- Cadence is understood to mean the number of folds set in speed in the conveying device per unit of time.
- the unstacking performance corresponds to the number of folds correctly introduced into the conveying device, that is to say presenting itself in a unitary manner with a correct trim and a synchronization as desired, relative to the number of theoretical folds likely to be speeded up.
