Definitions
- a device performing their unstacking ensures the automatic feeding of an indexing or readdressing and / or sorting machine for these folds.
- devices for unstacking flat objects essentially comprise a magazine for storing folds in a stack and an unstacking head at the end of a magazine.
- the unstacking head is equipped with suction and transfer means for the terminal fold of the stack.
- the store is, for its part, equipped with means for driving objects in a stack toward the head and means for presenting the terminal fold in front of the unstacking head.
- the means for presenting the pleats in front of the unstacking head must therefore ensure, as the pleats advance towards the unstacking head, in particular, the side jogging of the pleats, which must be presented at least in the end zone of the stack aligned on one of their edges, as well as the separation of the folds from each other in this same end zone. This allows the head to make sure and correct grip of the terminal fold put only from this single fold regardless of the characteristics of the terminal fold and those of the fold that follows it.
- These presentation means may include a lateral jogging edge on the magazine and means mounted in the bottom of the magazine and driven in rotation to push the folds against the lateral jogging edge.
- Document US-A 3 995 851 shows such a destacking device.
- the object store has a side bank along its length. This bank is in two independent parts substantially in the extension of one another and, with the end part at the end of the magazine that can be made vibrating and cooperating with the jogging means mounted in the bottom of the magazine, for better separation. objects in the terminal part.
- the store can also be equipped with means giving an inclination to the folds in its terminal area so that the terminal fold is presented with the foot against the the stop or the suction wall of the unstacking head.
- These latter means can be constituted by a set of motorized belts or a blowing ramp acting on the feet of the folds in this terminal area.
- the object of the present invention is to provide a device for unstacking objects which can have very different characteristics between them, leading by particularly reliable and simple means of operation to particularly improved performance.
- the subject of the present invention is a device for unstacking flat objects comprising a magazine receiving said objects in a stack, a unstacking head at the end of the magazine, means for advancing said objects in stack on the magazine, along a first lateral bank of the magazine and towards the unstacking head and, in the terminal part of the magazine defined facing the unstacking head where the jogging and straightening of the objects takes place, a second lateral bank substantially parallel to the first and said bank reference jogging with respect to the unstacking means, means for jogging objects and means for separating objects arriving in front of the unstacking means, characterized in that it further comprises a third lateral bank known as a transition and of straightening of objects mounted at the end of the first bank, extending inclined towards the outside of the store, from rear to front in the direction of advance of said objects, on the maje another part, known as the transition and straightening zone, of said terminal part of the magazine, said second reference bank being disposed in a rece
- the transition and straightening bank has an increasing inclination from upstream to downstream, with the upper edge of its terminal part more inclined than its lower edge.
- the unstacking head 2 is illustrated of the suction cup type 3 mounted on an arm 4 pivoting facing the terminal fold of the stack and movable in translation laterally in front of the stack.
- a stop 5 for the foot of the terminal fold of the stack is associated with the suction cup 3.
- This type of unstacking head is as such known. Its control means has therefore simply been shown schematically in 6, it drives the suction cup in a back and forth tilting movement, indicated by the double arrow 7, for the removal of the terminal fold from the stack, the foot of which passes over the stop 5, then in a forward and backward translation movement, indicated by the double arrow 8, for the lateral transfer of the terminal fold taken.
- This unstacking head is mounted in front of the open front face of the magazine on which the simple stop 5 for the base fold end of the stack is defined.
- Tray 1 is of the type with manual loading of a stack of folds; it is open at least on its upper side which is not referenced, advantageously has its bottom 9 inclined to the horizontal, with an ascending slope from back to front and has a retaining pallet 10 at the rear of the stack. He receives an unorganized pile of pleats to be deposed resting on edge on its bottom and retained by the rear pallet. It has an internal lateral flank 11 retaining, if necessary, the stack of folds during loading.
- This store is organized, according to its length considered from the rear of the store, into three zones denoted Zi, Z 2 , Zs.
- the zone Zi corresponds to the major part of its length, it constitutes a zone known in advance as folds in stack towards the unstacking head.
- Zone Z 3 of short length is the terminal zone in front of the unstacking head, it constitutes a so-called unstacking waiting zone.
- Zone Z 2 is the intermediate zone; it is called the transition and straightening zone of the folds; it receives the folds as they appear from the zone Zi and simultaneously ensures their jogging and their straightening during their passage towards the unstacking waiting zone Z s for their presentation as favorable as possible for unstacking in front of the head of unstacking.
- this store is differently equipped according to its areas.
- the retaining pallet 10 at the rear of the stack is also coupled to the chain 17, for its advance in synchronism with the stack of plies.
- This pallet is slidably mounted along a lateral guide 25 on the magazine and has a finger or lug 26 for hooking between the links of the chain 17.
- This protruding finger or lug at the bottom of the pallet ensures the advance of the pallet according to arrow F practically up to the stop 5, at which the chain, fleeing on its idler roller 19 under the magazine, escapes it.
- the return of the pallet to the rear of the magazine for a new loading of the magazine is ensured manually with a slight pivoting of the pallet avoiding during this rear return the catch of his finger on the chain while stopped.
- This edge 31 is fixed to the internal lateral flank 11 of the magazine; for this purpose, it has a vertical end portion fixed to the internal lateral flank 11 in the zone Z1 1 and then is inclined, with respect to the advance of the folds according to the arrow F, essentially along the zone Z 2 . Its end in zone 2 2 is offset from the jogging reference bank 30 of zone Zs, which is more external to the magazine and is extends behind the bank 31 in zone Z 2 .
- the jogging reference edge 30 is vertical.
- edges 31 and 30 are associated with two jogging rollers 35 and 36 and two screws 37 and 38 with helical threads with reverse pitch from one screw to the other and called advance and delay of folds.
- rollers and screws are mounted at the end of the magazine, with the screws interposed between the rollers. They are of axis parallel in advance according to the arrow F of the folds; they extend the bottom 9 of the magazine and the means for advancing the folds 12 which equip the bottom 9, up to the stop 5 while being in slight relief above the level of the bottom 9.
- a bottom front plate 39 is associated with the rollers and screws 35, 36 and 37, 38; this cut plate defines slots inserted in the intervals between rollers and screws, and extends the bottom 9.
- the threaded screw 37 following the roller 35 in the direction transverse to the magazine, is the screw for advancing the folds. It is threaded over the zone Z 2 , ie substantially over two thirds of its length; its end portion belonging to zone Z 3 is smooth and has its periphery substantially at the same level as that of the roller 35.
- This advance screw 37 is disposed substantially opposite the unstacking head 2.
- the second jogging roller 36 extends between the chain 17 and the delay screw 38, substantially on the external side of the magazine.
- the two jogging rollers 35 and 36 and the two advance and delay screws 37 and 38 are rotated from the same geared motor 40.
- a flat belt 41 and pulleys 42 with which tensioners 43 are associated ensure their training.
- the speed of rotation of the rollers and screws is chosen to obtain a linear speed of advance in zone Z 2 greater than that due to the straps in zone Z i and a linear speed of delay in zone Z 3 of same order of magnitude as that in zone Z i .
- a photoelectric cell 45 and an associated lamp 46 ensure the detection of folds in the unstacking waiting zone Zs.
- the lamp 46 is mounted above the lateral edge jogging 30 of the zone Z 3 practically at the end of the edge 31, the photoelectric cell is mounted on the opposite side, substantially at the end of the stop 5; they define an axis of detection of the folds crossing obliquely the zone Zs.
- This cell controls, when the beam emitted by the lamp is interrupted and then not picked up, in particular when there are folds in the zone Z s , l stopping the motor 20 ensuring the advance of the folds and, if not, starting it up. It also controls the stopping of this motor when the magazine is completely empty after a destacking operation, under these conditions the pallet having arrived in the zone Z s and interrupting the beam of the lamp 46.
- a second stop 50 in front of the stop 5, defines with the latter a chute for receiving the fold gripped by the suction cup 3 and for guiding the fold during its transfer in translation by the suction cup.
- the fold entered, which is transferred in translation along the arrow 8 between the stops 5 and 50, is then taken care of by a belt system generally designated by the reference 51, for its ejection and possible treatment.
- FIGS. 4 and 5 there is illustrated separately and on a larger scale the bank of transmission and straightening 31, seen from the front and from above.
- this bank 31 first of all has a vertical end tab 53 for attachment to the internal lateral flank 11 of the magazine.
- Horizontal buttonholes 54 provided on this tab 53 allow adjustment of the positioning of the edge at the end of the internal lateral flank of the magazine.
- the edge 31 proper is understood beyond the latching lug 53, it is inclined on the latching lug to extend towards the outside of the store and also widens over the height of the store.
- This inclined part has a first flat portion 55 adjoining the vertical hooking tab and a second curved portion 56 substantially along a frustoconical surface.
- the flat portion 55 forms with the hooking lug 53 a bias edge 58 after folding, on the face of the bank 31 facing the interior of the store.
- the folding angle, noted A is advantageously chosen to be of the order of 20 degrees, it gives the inclination of the edge relative to the advance of the folds according to arrow F.
- the lower edge of this planar portion 55 is parallel at the bottom of the magazine, its upper edge 59 is inclined to flare the bank in the direction of the front of the magazine.
- the curved portion 56 extends the planar portion 55, without any really visible transition therefrom. This transition is shown diagrammatically by the dotted line 57.
- the portion 56 results from preforming, then from polishing with the portion 55.
- the radius of curvature of its lower edge is substantially double that of its upper edge, to accentuate the inclination, towards the outside of the store, of the upper part of this portion relative to that of its lower part and thus reduce even the slightest effort to slide folds on this terminal portion of the bank 31.
- the radii of curvature R1 and R2 of its lower and upper edges tangent to the line 57 have been noted.
- the internal face of the store of this bank 31 is covered with a coating or with a non-stick film not shown, such as a polyvinyl chloride film.
- the advance of the folds as they have been loaded is ensured according to the arrow F by the belts 12.
- these are requested by the action of the slight transverse force exerted on their foot, by friction on the jogging rollers, for jogging the folds against the inclined flat portion of the bank 31, and simultaneously by the advancing action exerted on their foot by the advancing screw .
- the linear speed of advance of the folds in the zone Z 2 chosen to be greater than that of the advance of the stack in the zone Z i , releases these folds from the stack and allows the effective action of the jogging rollers.
- the jogging rollers and the smooth portion of the advance screw hold the folds against the jogging reference edge.
- the delay screw 38 continues its action on the folds; it gives the terminal fold a bias positioning of a few degrees relative to the stop 5, to avoid any possible packing of folds in this unstacking waiting zone Zs and a possible thrust which can lead to bonding of the terminal fold against the suction cup in rest position.
