Definitions

  • the present invention relates to a switching device in a plate element transporter, and in particular to a device switch within a conveyor belt arranged between the outlet of a machine for processing sheets of paper or cardboard panels successive and a stacking station to eject to an area of unloads the sheets or panels whose processing quality has been recognized as insufficient.
  • Processing machines can be cutting formats and / or printing one or more colors or metallized patterns on the cuts and / or folding the cuts into flat boxes. Potential faults can therefore be errors of register of the colors between them, or smudges of glue or incorrect bends, these errors being detected by devices automatic quality control, from cell readings photoelectric arranged on the passage of the elements.
  • the elements devices detected as imperfect are exited from the chain by devices points, also called ejectors, just before stacking in batches of delivery.
  • Document US 4 324 522 discloses a device of the same type designed to sort metal plates into different stacks and in which the selection tilting conveyor portion is the front end of a long feed conveyor.
  • the rear end of the next carrier may include a deflection plate rising simultaneously with lowering the adjacent selection portion to confirm the lowering of the plates to be ejected.
  • Document DE 1 223 682 describes a device for conveying sheets of paper or cardboard transported between two flexible belts, one higher, the other lower, moving at the same speed.
  • This device is equipped with a strike ejector which allows evacuation to the bottom of leaves that have been damaged or show a defect.
  • To make a deflection corner is placed facing the path of the leaves, slightly below, in front of a roll of the lower belt deflecting the latter down along one of the sides of the corner of deviation.
  • the leaf switch is controlled by a skate, which when actuated by the arm of an actuator coupled to an electromagnet, exerts a pressure on the upper belt in the direction of said roller deflecting the lower strap.
  • Document US 3,417,989 describes an apparatus allowing inspect sheets of paper and separate those that are acceptable of those who are not.
  • the leaves are moved by a transporter on a suction surface of variable effective width, in front of detection organs. They are referred, in two possible ways, by the tilting of a pair of rollers around which a belt turns unending. This pivoting member is placed above the deflection roller said carrier. The referral is completed by a diversion corner placed facing the conveyor roller, slightly below it.
  • the ejected plate elements in particular cardboard boxes, are not always sufficiently well controlled, i.e. are neither required nor entrained along their deflection and ejection path, which can lead to situations of occasional accumulations, even jamming, requiring the machine to stop.
  • Document FR 2 688 493 discloses a cutting device and change of direction of a non-conforming portion of a treated strip continuous.
  • This device comprises, between two vertical pairs of belt drive rollers in a normal horizontal path, a forward and downward oblique deflection plate, plate of which the upper edge located slightly below the normal path is shaped as anvil.
  • a lower flap with separating blade normally in high position guides the strip above the plate.
  • the lower flap lowers, and a flap upper separator with a blade edge descends in rotation against the anvil to cut the strip and direct it along the plate towards an ejection path where it is pulled by traction rollers.
  • the separator flap upper rises and the lower flap hits the anvil to cut new strip and steer the new front edge of the strip towards of the normal trip.
  • This device intended for treating a continuous strip is however ill-suited and too complex, therefore too expensive, to process elements in successive plates which should not be cut and in front, preferably, be practically permanently trained by a transporter either strip or close parallel rollers.
  • the object of the present invention is a referral device to the within a plate carrier which is first particularly reliable, i.e. capable of applying a change unambiguous direction to the element so that it cannot collide with a mechanical organ. If necessary, the device must be able to effectively imprint a curvature on the element, even of strong grammage, when switching to the new direction.
  • This system must also be particularly dynamic, that is to say have a very fast changeover time, to be able to follow high production rates.
  • the number of organs mobile of the switch should be as small as possible and have each a low mass and / or inertia.
  • the operation of this device must also consume relatively little mechanical energy.
  • this referral device occupies a space as small as possible to make room for a bin recovery, to drive means on the ejection path, and place to operate parts during maintenance or repair.
  • front and rear we mean a direction considered with respect to the direction of scrolling of the elements, that is to say respectively downstream and upstream of the supply of plate elements.
  • length of an element is also taken in the direction of scrolling, a “width” being perpendicular to it in a horizontal plane.
  • a conveyor with one or more belts arranged in the direction of scrolling of the elements, and passing along an upper path over them rollers and returned to the ends by pulleys along a path lower return, one of the pulleys being for example motorized, i.e. a conveyor composed of a series of parallel rollers transverse to the direction of travel of the strip and arranged one after the other, these rollers being all driven at one of their common ends by the same belt.
  • the invention consists in taking advantage of the form convex of the semi-cylindrical front periphery of the last roller or roller front of the first rear lower conveyor to apply using a means of deflecting a curvature to a plate element whose stiffness intrinsic minimum would normally have kept its trajectory normal passing through the first side of the switching means then the second lower front conveyor, this curvature making it take on the other hand a second path known as ejection, this second path being quickly confirmed by the second oblique side of the switching means.
  • this referral is all the more effective when one at less of its components, i.e. the latter roller or roller of the former conveyor, is rotated, therefore forces the element to advance in plate in one direction as in the other.
  • the means of diversion are made up by a band passing under the lower front periphery of a roller or front end roller belonging at the front end of a rear portion of a single upper belt conveyor continuing in an upper loop.
  • the means of deflection include two skates deflection arranged on either side of the roller ensuring the curvature over the entire width of the front edge of the element in plate.
  • the ejection conveyor starting with a pair of motorized rollers mounted opposite is arranged following the oblique side of the switching means, if desired one or both rollers being the departure of a conveyor belt.
  • This ejection conveyor arranged immediately following the means of referral avoids any risk of jamming of plate elements deviated, and this by voluntary training of these elements including a higher speed than that of the normal journey.
  • the distance between the pair of rollers or rollers defining the end of the first rear lower conveyor and either the pair of rollers or rollers defining the start of the second lower conveyor before either the pair of rollers or rollers defining the start of the conveyor ejection is less than the minimum length of an element, in plate.
  • the second lower front conveyor is mounted on a movable frame tilting forward to facilitate access to switching means, deflection means and ejection conveyor for maintenance and repair.
  • Figure 1 is illustrated as a whole a conveyor bands belonging to a separation station.
  • One such station is intended to detach a plurality of poses printed and cut out a sheet of cardboard side by side in the width direction and according to several successive lines in the length by different stations of rotary or platen cutting and printing behind, that is to say on the right side of FIG. 1.
  • This separation station therefore comprises several belt conveyors arranged side by side in fan so as to separate the poses in the width direction, these carriers having a higher speed of advance than stations previous to also separate these poses in the direction of the length.
  • Each of the belt conveyors brings the poses according to a substantially horizontal path Tn to a stacking station corresponding located in front, that is to say on the left side of FIG. 1, and also includes a more visible switching device 26, 32, 42, 60 in Figure 2 illustrating in an enlarged manner the front part of this carrier.
  • This referral device allows clearing along a path Te poses of insufficient quality to a recovery tank 79.
  • each pose passes individually under a reading area including for example a camera and / or reading cells, detecting errors printing, for example color register errors between them, or traces or smudges of glue, or even non-conforming folds, this reading area being connected to electronic means and / or computers ordering the switchover of the switch as soon as the passage from the rear edge of the last conformal pose is detected by another photocell placed close behind this switch.
  • a reading area including for example a camera and / or reading cells, detecting errors printing, for example color register errors between them, or traces or smudges of glue, or even non-conforming folds, this reading area being connected to electronic means and / or computers ordering the switchover of the switch as soon as the passage from the rear edge of the last conformal pose is detected by another photocell placed close behind this switch.
  • this belt conveyor first includes a first lower conveyor belt 40 performing a horizontal top path passing over a plurality of rollers of support 44 until reaching a last front roller 42 returning this belt along a lower path where it goes through a tensioning mechanism and a lower drive axis before being twisted and then returned towards of its horizontal upper path.
  • the steering and support rollers 42, 44 of this conveyor 40 are arranged on a lower vertical plate support 41 mounted at its rear edge in pivoting on a hinge 39 integral with the chassis of the separation station.
  • this transporter includes a second lower front conveyor 50 whose belt begins its journey horizontal upper passing through a first rear roller 52, continues it passing over support rollers 54, this belt being returned to its lower return path by its front end roller 59.
  • these support and guide rollers 52, 54, 59 of the strip 50 are mounted on a vertical support plate 58 capable of being tilted forward for access to the switching device if necessary.
  • this plate 58 is at this effect mounted through a pivot 48 to a plate bracket 51 which can be adjust the position along a through beam 53 of the station separation.
  • This beam 53 is carried on either side of the chassis of the station by two lateral T-shaped tilt plates 55, one straight and a left, pivoting respectively around their pivot 57.
  • the T plate 55 can be tilted by its jack 49 acting between a fixed point of the chassis and its rear branch. So the position and orientation of each of the vertical support plates 58 lower front carrier 50 can be adjusted to be in the alignment of the lower vertical support plate 41 of the first lower conveyor 40.
  • this conveyor includes a single upper conveyor 30 making a substantially horizontal lower path passing under support rollers 35, and this in correspondence with the upper paths lower carriers.
  • This top carrier is then returned along an upper return path being guided by rollers 38 where it goes through different tensioning devices and a higher axis back training before returning to his training path inferior.
  • the path lower of this belt 30 describes a loop oriented upwards at the level of the referral device 60 being successively guided by the roller 32 at the front end of the rear portion of the upper conveyor, two upper rollers 34, 34 ', then returned by an end roller 36 rear of the second front portion of this upper conveyor.
  • This deflection loop has a substantially T-shaped, that is to say that the belt 30 is wound on the one hand at least on the front half of the periphery of the roller 32, the roller 34 being situated behind this roller 32; and on the other hand wraps at least on the rear half of the periphery of the roller 36, the roller 34 'being situated in front of this roller 36.
  • the two rollers 32 at the front end of the portion rear and rear end 36 of the front portion are both mounted on a lever 20 belonging to the switching device.
  • the device switch firstly comprises a switch angle 60 interposed, under the normal path Tn, between the front end roller 42 of the rear lower conveyor 40 and rear end roller 52 of the lower front conveyor 50.
  • This return angle is a machined part having a rear angled cross section.
  • the face upper 62 of this machined part constitutes the first side of the angle provided to catch up with the normal path Tn, and is formed by a rear plane horizontal, followed by an oblique intermediate plane going up and ending in a third front plane also horizontal.
  • the rear underside 64 constitutes the second side of the angle provided to guide the ejection path Te, and is formed from a downward oblique plane at an angle of about 60 ° by compared to the horizontal.
  • This workpiece is held by two bolts side plates whose oblique rear edges extend the second side deflection oblique 64. Little below the machined part is arranged, between these side plates, a first roller 73 of an ejection belt 74 passing through a lower pulley 76 movable under the effect of a device elastic not shown to tighten this belt. At this pebble upper 73 of belt 74 is arranged a large motorized roller 72 rotating at a peripheral speed higher than that of the transporters of so as to eject the defective elements very quickly.
  • Pinch point 70 for resumption of ejection drive between the rollers 72 and 73 is located a short distance from the generator upper of the front end roller 42 of the lower conveyor 40, in particular less than 80 mm minimum length of the poses planned to be processed by this separation station. It should be noted that the distance between the recovery point 56 of the front transporter on the normal route Tn constituted by the two upper rollers 36 and lower 52 is also located a short distance, on the order of 80 mm, from the generator upper roller 42 where the installation is released by the rear conveyors.
  • the ejection belt 74 directs the ejected poses in a conduit formed by the guide rails 77 and 78 bringing the poses ejected into the recovery tank 79.
  • the switching device further comprises a lever 20 better visible in Figures 3 and 4.
  • This lever comprises on the one hand a short arm 24 substantially horizontal arranged slightly above the referral angle 60 and of the roller 42, and on the other hand a long, substantially oblique vertical arm 22 forward.
  • This lever 20 pivots about an axis supported by a bearing 36 ' of the upper support plate 31 ′, this axis also carrying the roller 36 rear end of the second front portion of the upper conveyor 30.
  • the short arm 24 door, substantially in the middle, the roller 32 at the front end of the portion rear of conveyor 30 and, at its rear end, a vertical bridge 25 supporting two pads 26 on either side of the roller 32.
  • These pads are present in the form of plates slightly oblique to the horizontal, of width corresponding substantially to that expected of the poses.
  • the roller 32 is arranged on the short arm 24 so that its rear half is at the same level as half front of the end roller 42.
  • the front half of the pads 26 is also located at the level of the front half of the roller 42, this half with a lower arched face, for example semi-cylindrical angle at the top between 10 ° and 30 °.
  • the lever 20 can take two positions. In the first position, the short arm 24 is in the high position so that the belt 30 guided by the roller 32 and the shoe 26 do not interfere not with the normal path Tn of the poses. In the second position marked by the reference 26 ′, the short arm 24 is in a low situation causing the rear part of the pads 26 and the belt 30 guided by the roller 32 surround a portion of the upper front periphery of the end roller 42 so as to force a curvature of the poses downwards. This curvature is such that the front edge of the installation necessarily passes under the oblique deflection side 64 of the referral angle 60.
  • this front end roller 42 of rear conveyor 40 constitutes a bending roller on which a pose is bent forward and downward due to an imposed deviation jointly by the pads 26 and the belt 30 passing under the roller diverter 32 lowered.
  • This curvature imposed between the end roller lower front and bending 42 on the one hand and the combination of pads 26 and of the upper front end and deflection roller 32 on the other hand works better as the lower 40 and upper 30 belts force the advance of the installation even under this constraint.
  • the movement of the deflecting skids / rollers between position 26 of non-interference and lower position 26 'of deflection is all the better imposed as the other lever arm 22 is long.
  • This long lever arm 22 is controlled by the end of the actuating rod of the pneumatic cylinder 28 whose rear of the body is supported by an extension vertical 31 "located at the end of the upper vertical plate of support 31 '. Switching the switch in one direction then in the other can therefore be particularly fast, thus making it possible to follow particularly high transport speeds, for example of the order of 500 meters per minute.
  • the switch according to the invention can be integrated into a small conveyor width, but could easily be adapted to a switch for a wider carrier by changing the initial pads to larger ones.
  • several carriers can be provided side by side with their associated deflection devices which would then be actuated simultaneously.
