Definitions

  • the objects handled can be transported on conveyors offering a simple horizontal support. This is particularly the case with items such as bottles, jars or other glass containers. Their production and even more the packaging operations of the products for which these containers are intended are carried out at very high speed, in particular in the bottling and require the use of automatic machines.
  • the machines in question, whether control, filling or capping, etc. are generally barrel machines fed by a chain of horizontal conveyors on which the articles, bottles for example, are simply placed: a star wheel takes them one by one to separate them and present them in turn, continuously or not step by step at one or more work stations, before releasing them onto the next section of conveyor.
  • an ejector consisting of a transverse pusher moved by a pneumatic cylinder over a distance of the order of the width or diameter of the object, or, when relatively light objects are involved, a nozzle emitting a sufficiently violent jet of air in their passage.
  • sorting machines in which members such as a set of jaws or suction cups mounted on the star wheel opposite each cell and controlled by a distributor grips the necks to release the accepted bottles and the rejected bottles separately, at different instants-of-the-rotation-cycle, so as to direct them towards two different conveyors.
  • These machines are capable of operating at fairly high rates, but they are of rather complex construction and relatively delicate operation, and, designed for a determined angular pitch, they adapt quite poorly to changes in manufacturing corresponding to a significant change. shape or size of the articles, so that they are expensive, delicate to maintain and do not always have the desired flexibility of use.
  • this device then consists of an endless band which carries pushers capable of gradually pushing back towards the auxiliary conveyor, when they are actuated by a fault signal emanating from the control station, the bottles or flasks that should be discarded.
  • Patent publication DE-A-29 36988 describes in particular a vertical axis ejector wheel mounted opposite the star distributor wheel, synchronized with it and equipped, according to a pitch corresponding to its own, a series of ejector fingers articulated on vertical axes placed at their upstream part. In order to eject the bottles, these fingers press against their surface to keep them in contact with the dispensing wheel.
  • the invention as claimed is intended to provide a similar ejector wheel but more progressive action and more compact structure.
  • this wheel is equipped with ejector fingers articulated on axes placed at their downstream part and having a useful convex bearing which runs at rest along the periphery of the wheel.
  • the finger after coming into contact with the bottle, deploys by rolling roughly without sliding along its surface and without imposing a shock on it.
  • these fingers are not normally arranged in one, but in two peripheral rows superimposed in staggered rows or better still nested.
  • the outside diameter of the ejector wheel will be of the order of half or one third of the diameter of the circle defining the trajectory of the articles along the dispensing wheel.
  • the ejector wheel can itself be a star wheel meshing in a way on the distributing wheel by means of the containers but, at the high operating rates used, it is preferable, even essential, that it be synchronized independently on the latter via a mechanical transmission or an electronic synchronization device. In such a case, it is not necessary that the ejector wheel is a star wheel, it is even possible to admit between the two wheels a certain slip which makes it possible not necessarily to change the ejector wheel when one modifies, within a certain range, the pitch of the control machine with a view to a change of manufacture.
  • the ejecting fingers are passive organs permanently pushed outwards by a spring or similar elastic means but normally retained in the rest position, retracted, by a fastening member, so that their external reach runs along the periphery of the ejector wheel.
  • the action of a jack the operation of which is conventionally caused by an ejection signal sent by the control station when a defective article passes, releases a finger at the desired time to allow it to come to bear on the outer wall of this article and then gradually deploy, thus maintaining the article in position in its cell on the distributor wheel until it has crossed the normal exit zone towards the main conveyor and has engaged on the auxiliary elimination circuit.
  • This jack is preferably placed at a fixed position and, likewise, the deployed fingers are then brought back into the locking position by an external reset member arranged at a fixed position.
  • an external reset member arranged at a fixed position.
  • It can again be a jack, but more simply a passive member comprising a reset roller or a cam so as to push the desired fingers back into the hooking position, one of these elements then advantageously disappearing under the action of a spring until the reset member is again urged by a deployed finger following the subsequent ejection of a new article.
  • This element may in particular include a chin mechanism.
  • the machine shown as a whole in FIG. 1 is placed along a conveyor 1, at the outlet of a system of lateral guides 2. It mainly comprises a barrel carrying a star-shaped distributing wheel 3, having two superposed platers whose teeth 4 grasp one by one, at the height of the barrel, the bottles 5 waiting on the conveyor, spacing them slightly apart, then present them in turn, on a circle D, in front of a control station shown diagrammatically at 6, while 'An endless belt 7, circulating on pulleys 8 in front of the wheel 3, rotates them inside the cells of the latter.
  • the diameter of the circle C of contact with the strip 7 will preferably be approximately constant from one manufacture to another and, for example, of the order of 750 mm. In the case shown in the figure, there are 24 of these cells, spaced 15 ° apart.
  • the bottles are normally taken up by the conveyor 1, but a system of two guides 9a and 9b acting the first at the level of the barrel of the bottles, the second at the level of the neck to obtain a better stability, also draws a branch towards a bypass 10. Opposite this bypass and opposite the distributing wheel is placed the ejector wheel 11.
  • the periphery of this wheel carries a succession of ejector fingers 12, each of which is articulated on an axis 13, and pushed outwards by a spring 14, but carries a lug 15, which allows a trigger 16 to retain it in the retracted position along a circle E defining the periphery of the ejector wheel, at a distance from the axis of the distributing wheel corresponding, apart from the clearances, to the radius of the contact circle C. If necessary, a pusher 17 will release one of the fingers opposite one of the bottles to cause the ejection of the latter by pushing it towards the bypass 10. In the figure two bottles are thus being ejected.
  • the device also includes a member 18 for rearming the ejector fingers, the operation of which will be described below.
  • the ejector wheel can have, for example, twelve ejector fingers distributed in two superimposed series of six fingers 12a, 12b spaced 60 ° apart, themselves offset from each other by 30 °. Its center will then be placed at a distance from the circle D equal, apart from the clearances, to half of its radius, and its angular speed will be twice that of the distributing wheel.
  • the two wheels thus rotate without slipping, a finger appearing regularly in front of each cell; they are therefore possible to equip the ejector wheel with a star 19, in particular to facilitate evacuation on the downstream strand of the conveyor 1 if the latter makes with the direction of exit of the bottles a more pronounced angle than that shown.
  • the wheels mesh to a certain extent by means of the bottles which they trap, and because of the essential games it remains necessary in practice, to ensure its synchronization, to provide a separate drive of the ejector wheel , to allow very high operating rates and to avoid any incident in the event of an interruption in the supply of the machine.
  • the ejector fingers 12 have a length of the order of one and a half times the diameter of the bottles and a curved shape, which moreover gives them an outer reach 20 more convex than the periphery of the ejector wheel.
  • the spring 14, wound around the axis 13 of each finger and trapped the bearing 21 thereof and a pin 22, tends to push it outward until its bearing 23 comes in stop on the pin 22.
  • the hooking lug 15 of each of the fingers is formed of a bolt which is screwed onto the finger and that a lock nut 24 makes it possible to block in the suitable position.
  • the reset member 18 essentially comprises a cam 25, pushed back towards the ejector wheel 11 by a force limiting spring 26 and carrying one or two reset rollers 27.
  • a semi-positive switching member 28 resiliently biased towards the ejector wheel, in position 28 '.
  • this member positively directs the articles in the direction of the main outlet, corresponding to the downstream strand of the conveyor 1 ensuring them continuous guidance, but, if the force which it exerts, taking into account the arms respective levers, is less powerful than that of the ejector fingers 12, when one of these fingers is deployed in front of a bottle to be ejected, it maintains it in its cell on the dispensing wheel and this bottle repels the switch 28, the gradually moving away to engage towards the diversion 10.
  • the switch 28 advantageously consists of two or more independent blades 28a, 28b of different lengths, hinged here on the same axis 29 located upstream and capable of returning to rest independently of each other under the action of separate springs 30a, 30b as soon as the bottle being ejected has passed them, so as to be ready to guide the next bottle towards the main conveyor, unless it is necessary to eject it at his turn.
  • the ejector wheel comprises a hub 31 carried by a shaft 32 and integral with a drive pinion 33 synchronized by a suitable transmission, not shown, with the device for driving the barrel of the distributor wheel .
  • the hub 31 carries a web 34 and also receives two flanges 35a and 35b.
  • the axes, or 13a and 13b which respectively receive the pushers, or 12a and 12b, on the other hand the pins 22a, 22b.
  • the head of the lug 15 has a conical anterior part 151 and forms a shoulder 152 at its posterior part.
  • triggers On either side of the hub 31 are also mounted two series of triggers, namely 16a, 16b, resiliently biased upwards so as to retain the ejector fingers 12a, 12b respectively.
  • these triggers consist of a plate 161 carrying upward, at its end, a tenon 162 and mounted on a spring leaf 163. At rest, the tenon 162 comes to hang behind the shoulder 152 formed by the rear face of the head of the lug 15, and thus retains the erased finger along the periphery of the ejector wheel.
  • Two sets of detent pushers, 17a and 17b, rest alternately on the triggers 16a and 16b, which they are able to push down, thus releasing the lug 15 and consequently the corresponding ejector finger 12.
  • the action of the ejector finger appears in FIG. 5: in the event of the passage of a defective bottle, the fault signal emitted by the receiver 6 triggers the operation of the jack 36 with a suitable delay and thus releases the ejector finger which appeared in front of the bottle in question.
  • the convex outer surface 20 of the latter presses against the barrel of the bottle, in the manner indicated in phantom, in 1, in the figure then, gradually unfolding in the manner of an elastic cam, maintains the bottle in its cell, as already seen in Figure 1, pushing the two blades of the switch 28.
  • the finger 12 finally escapes to come into abutment on the pin 22 (position 2) while the bottle, already engaged by him on the bypass is now retained there at the neck by the guide 9b and also comes into contact, at the barrel, with the guide 9a.
  • the deployed finger finally arrives, as seen in 3 in the figure, in contact with the rearming member 18, the cam 25 of which forces it to gradually fold back; the ramp formed by the conical surface 151 of the head of the lug 15 finally comes into contact with the tendon 161 and begins to push the trigger 16 down.
  • the finger then reaches the roller 27; the latter still pushes it inwards (position 4) so that the ramp 151 of the lug 15 passes beyond the lug 162 which then rises behind the shoulder 152, again locking the finger 12 which then escapes to return to the position of complete rest, that is to say slightly projecting from the position of the roller 27.
  • the machine of FIG. 6 has a structure very similar to that of the previous machine and the corresponding references have been kept for the homologous members. However, it is particularly intended for small bottles circulating at very high rates; this is why the distributing wheel 3, the external diameter of which is unchanged, is equipped with thirty-six stations. Twice as small, the ejector wheel 11, which is mechanically synchronized, carries eighteen ejector fingers and rotates at double angular speed. The above data lead to an ejector wheel clearly more compact than in the previous versions.
  • the machine drawing is designed so that all the fingers can act under identical conditions, the active part 20 ′ of their convex surfaces 20a, 206 being placed at the same height, in this case located opposite the area of larger diameter of the bottles so as to form a single band; to this end, the hinge pins 13a, 13b of the fingers and all of their hooking and ejection mechanisms are alternately offset on either side of this strip, which makes it possible to 'house them easier.
  • the hub 31 carries two separate webs 34a, 34b; the axes 13a of the fingers 12a, their springs 14a as well as the pins 22a are carried by the cheeks 34a, 35a, the corresponding members of the fingers 12b by the cheeks 34b, 35b.
  • the fingers have the shape of L-shaped paddles, two to two symmetrical, and the two webs 34a, 34b are cut alternately at 39a and 39b to let their ends pass, whose outer surfaces 20a, 206 thus align in one ejection strip 40 between the two adjacent cheeks.
  • the attachment members, pins 15 (a and b) and triggers 16 (a and b) similar to those of the previous versions, are visible from place to place in FIG. 7.
  • column 4 corresponds to the joint use of the distributing wheel of column 3 and of an ejector wheel according to column 2, devoid of drive star 19, the speed of which has been increased to introduce a slip of the order of 7% which allows the respective stations to remain face to face during operation.
