Definitions

  • the present invention relates to a device for selection of cardboard blanks cut on a dispensing machine, in particular to to eliminate from a flood of products those which are considered as defective.
  • the present invention relates to in particular a selection device allowing significantly improve the pace of selection.
  • sorters able to sort products of around 30 cm in length when traveling with a speed of the order 180 m / min, which represents a selection of 600 products per minute. In such conditions it is estimated that the reliability of sorting is of the order of 99.7%.
  • the object of the present invention is to provide a selection device able to improve both the number of selections possible per minute as well as the reliability of it.
  • the concavity of the curve is oriented on the side of the flap and the front part of the upper side of the flap curves down.
  • the lower path of the belts blanks drive at least in the upstream parts and downstream close to the pivoting flap, forms a curve whose the radius of curvature is substantially uniform, the concavity of the curve being preferably oriented on the side opposite the flap.
  • the underside of the shutter may have a curvature close to that of the belt below it, so that normal operating position, it defines with this a substantially parallel path.
  • the device according to the invention comprises preferably means capable of maintaining the blank of cardboard, at least when it passes through the flap, on at least part of its surface, between two holding elements of which at least one is constituted by a bit of belt.
  • the other holding element can be formed by another strand of belt or by a roller.
  • the device includes at least four belts which define the two upper and lower paths.
  • a first portion of the lower strand of a first belt or strap upper, and a first portion of the upper strand of a second belt, or lower belt are in contact, and downstream of the shutter a second portion of the strand lower of the first belt is in contact with the upper strand of a third strap and a second portion of the upper strand of the second belt is in contact with the lower strand of a fourth belt.
  • An upper strand of the fourth belt can also be in contact with the lower strand of the third belt.
  • Each module will thus have its own mechanical drive system, consisting in particular of four belts, and its own selection system, consisting of a pivotally mounted flap.
  • This component may be mounted on a movable lever around an axis of rotation downstream under the action of a jack controlled by a valve fast pneumatic powered by an air tank under pressure. It is therefore particularly easy to modify the relative positioning of several modules according to the different specific applications of the device.
  • all the mechanical elements of the device can be arranged on a plate unique so as to constitute an adjustable module and positionable independently.
  • Figure 1 is a schematic plan view of a mode of implementation of a following selector device the invention.
  • Figure 2 is a diagram illustrating the functioning of the selection means used in the device according to the invention.
  • Figures 3a and 3b are vertical sections and enlarged partial longitudinal showing the area of the two paths and the selection pane in the upper and lower positions respectively.
  • Figure 4 is a perspective view of the mode of implementation of the invention shown in FIG. 1, the selection means being removed.
  • the following device basically consists of four belts.
  • the first and second belts respectively upper 1 and lower 2 are wound on rolls 5,5a and 7,15,17 so as to form an upper loop and a lower loop.
  • the device also includes a third belt 3 whose upper strand 3a is in contact with the strand 1b of the first belt 1, so as to marry the shape thereof, and a fourth belt 4, the lower strand 4a is in contact with strand 2b of the second belt 2, so as to match its form.
  • the lower strand of the belt 1 is separated into two zones, namely an upstream zone 1a which is rectilinear and a downstream area 1b which is curved.
  • the upper strand of the belt 2 comprises a first zone 2a which is straight, followed by a second area 2c at a bifurcation zone, which is curved with a smaller radius curved, downwardly concave the action of rollers 13 from a third zone 2b to concavity oriented upwards by the action of rollers 12.
  • Intermediate belt 3 has an elongated shape and is arranged under zone 1b, so that its strand upper 3a is in contact with zone 1b.
  • rollers 11 give strand 3a and zone 1b a curvature, concavity oriented downwards which, besides the benefit currently mentioned also has the effect to improve the contact of the belts and therefore their mutual training.
  • the lower loop formed by the belt 2 is ends with a series of tension rollers 15 and a drive roller 17.
  • Belts 3 and 4 are arranged such that the lower strand 3b of the belt 3 either in contact with the upper strand 4a of the belt 4. Such a provision allows to train the whole belts using a single drive belt, know the belt 2 itself driven by the roller motor 17.
  • the device also includes means for selection, consisting of a flap 6 mounted pivoting around of a downstream axis O parallel to the axes of rotation of rollers 5 and 7.
  • This flap 6 is able to occupy two positions, namely a low position, or position of normal operation (which corresponds for example to passage of correct blanks), and a high position, or selection position (which corresponds for example to a defective blank selection position).
  • the shutter 6 is normally in the low position, but it is likely to move up to each time a blank to be selected is detected.
  • This detection is carried out by an anomaly detector, not shown in the drawing, which can be of any type appropriate to the parameter you wish to control.
  • the detector is arranged at a distance from shutter 6 which is sufficient so that, given the speed of displacement of the parts of belts 1a and 2a, and therefore of a cardboard blank transported, means of analysis, not shown in the drawing, have time to analyze this one and decide the upper or lower path that he has to follow.
  • a second detector, or passage is arranged downstream of the anomaly detector, preferably near shutter 6, and order the upward tilting of it when the means of analysis have decided to go through the lower path blank.
  • the Applicant has found that by conferring on the upper path followed by the cardboard blank, or path normal operation, regular curvature at upstream and downstream neighborhood of the selection flap 6 and in giving the posterior part of the upper side of this one a curve close to that of the belt which was superior to him, it was possible to increase in a high proportion the number of cardboard blanks selectable by device. Indeed, with prior art devices it was possible to control the passage of around 600 blanks per minute with a number of operating incidents of the machine (stuffing) of about one in 24 hours of operation. The device according to the invention has allowed to control the passage of 1000 cardboard blanks per minute with only one incident in 800 hours Operating.
  • Cardboard blank is allowed between strands la and 2a of the contact portion of the first and second belts 1 and 2, and is driven by them in direction of the selection panel 6.
  • flap 6, in a time tl given tilts up and the blank appears in front of the flap 6 is then routed by it between the strands 2b and 4a of the belts 2 and 4.
  • shutter 6 remains in the low position and the cardboard blank is then routed between the strands 1b and 3a of the belts 1 and 3.
  • the strands 1a and 2a of belts 1 and 2 are in contact but deviate from one of the other at a distance from the front part of the flap 6.
  • the most upstream zone of the belt 3 is in contact with strand 1b at a distance from the front part of the flap 6.
  • the length of the blanks of carton must therefore be greater than the sum of these two distances if you want at least part of this is maintained at all times by two strands of belt namely the strands 1a and 2a then the strands 1b and 3a.
  • the bifurcation zone upper and lower paths constitute an angle about 20 ° whose sides are curved, both concavities being oriented downwards.
  • the rear part 6a of the face upper part of flap 6 is parallel to the curvature of the strand belt 1b above it, when the flap 6 is in the high position, while its front part 6b is curved further down.
  • the face lower part 6c of flap 6 is parallel, over its entire length, to the belt strand 2c which is less than it when the flap 6 is in the low position.
  • the means of selection may include an air reserve under pressure 14 which supplies a fast type solenoid valve 16 which is itself connected to a jack 18. This acts on one end of an arm 20 pivotally mounted around an axis 22 which ends with the flap 6.
  • the solenoid valve 16 is controlled by the sensor 10a via of an interface 24. When a defective blank is detected by the anomaly detector detector 10a in passing of the blank controls the opening of the rapid solenoid valve 16 which allows the pressurized fluid contained in the reserve 14 to be admitted into the cylinder 18 including the piston moves down so that lever 20 pivots around its axis 22 which has the effect of displacing the flap in high position.
  • the selection device according to the invention can be used with machines separating a strip of carton in any number of sets of blanks of cardboard. Depending on the specific use, it is interesting to be able to convert easily and quickly a machine comprising a given number of devices for selection arranged in parallel in a machine having a different number of these selection devices.
  • the present invention is particularly suitable for such a quick conversion, as long as it promotes the creation of a modular structure.
  • Each of the basic modules of this structure includes a set of belts and means of selection consisting in particular of a pivoting flap and control means thereof, so as to be completely autonomous. In this way it is possible to easily arrange, depending on specific needs, the number of modules required for an application determined.
  • such a module essentially consists of a plate 30 supporting axes on which the various are rotatably mounted rolls 5,7,15,17 around which are wound the upper 1 and lower 2 belts as well as the intermediate belts 3 and 4.
  • the plate 30 is crossed by a slot 33 which extends from the side cardboard blanks which separates in two divergent slots at the level of the selection flap 6, of to follow the path of the belts.
  • This slot 33 allows the use of cardboard blanks that have a width greater than that of belts 1,2,3,4.
  • the flap 6 and its actuating means are fixed on the side of the plate 30 where the rollers. For reasons of clarity of the drawing they do not are not shown on this one.
  • the means of shutter 6 control for reasons of space saving are preferably placed on the side of the plate 30 where the belts are installed.
