Definitions

  • This invention concerns a device for coupling and/or uncoupling conveyor elements in relation to a driving mechanism.
  • the invention concerns driving mechanisms which mainly consist of a continuously moving driving element, such as an endless drag chain and conveyor elements, which usually consist of trolleys, and which are coupled to such a drag chain by means of a coupling part provided onto it, such as a drag pin, which works in conjunction with the driving element.
  • a continuously moving driving element such as an endless drag chain and conveyor elements, which usually consist of trolleys, and which are coupled to such a drag chain by means of a coupling part provided onto it, such as a drag pin, which works in conjunction with the driving element.
  • the known devices are disadvantageous in that they are easily damaged. This damage is caused when the above-mentioned rotatable element jams and the driving element continuous to exert a force on it, whereby either parts break off, or gears are damaged, or also the driving element is put out of order.
  • the invention aims to provide a solution to this.
  • the invention concerns a device for coupling and/or uncoupling conveyor elements in relation to a driving mechanism, consisting of a rotatable element in which is provided a guide for a drag pin of a conveyor element, and driving means to rotate the rotatable element, such that a conveyor element, as a result of the rotation of the rotatable element and by putting it in a given angular position, can be uncoupled from and/or coupled to the driving mechanism, characterized in that means are provided between the driving means and the rotatable element which can give away when the rotatable element jams.
  • connection can give away should the rotatable element jam, and the driving means can continue to function normally without being excessively loaded, such that any damage to these driving means is excluded.
  • connection will consist of axially slidable parts in between which are provided springs.
  • connection can be provided with a spring which allows at least for an extension of the connection. According to a variant, it can be provided with a spring which allows at least for a shortening of the connection.
  • the device will be designed double-acting, such that the connection can give away in both directions, in other words such that it can both be elongated and compressed under a normal load.
  • the invention is especially useful in the case of a positive drive, such as a drive by means of an electric motor.
  • the conveyor element 2 can hereby be moved by means of a drag pin 4 or such.
  • the drag pin 4 can hereby be taken along by a protrusion 5 provided on the driving element 3.
  • the rotatable element 6 can have various forms, but it preferably consists of a disc which can rotate around a pivot 9, whereas the guide 7 provided in it consists of a recess which is confined by two guiding edges 10 and 11.
  • the guiding edge 10 stretches such that the drag pin 4 of an approaching conveyor element 2 is guided outside the path of the driving element 3 according to the course X represented in figure 2.
  • the above-mentioned driving means 8 consist of an electric motor 13 and a crank mechanism 14 which is driven by the motor 13 and which converts the rotating movement R in a to and fro rocking motion T of the rotatable element 6.
  • This crank mechanism 14 may for example consist of a crank rotating around a pivot 15, in the shape of a disc 16 which is driven by the motor 13 via a gear transmission 17, and a connecting rod 18 which is connected to the disc 16 by means of a pivot 19 on the one hand, and which is connected to the rotatable element 6 by means of a pivot 20 on the other hand.
  • means 21 are provided between the driving means 8 and the rotatable element 6 which can give away when the rotatable element 6 jams.
  • these means 21 are part of the above-mentioned connecting rod 18. It is clear, however, that these means 21 can also be provided in another place.
  • these means 21 preferably consist of an elastic, deformable connection, in this case between the pivots 19 and 20, which is designed such that it offers some initial resistance against deformation, so that when the device 1 functions normally, there is no or almost no deformation and the distance between the pivots 19 and 20 remains unaltered, but when the rotatable element 6 jams, the connection can be elastically elongated and/or compressed, such that the driving means 8 can carry out a normal working cycle.
  • the above-mentioned elastic, deformable connection preferably consists of a cylinder 22 with two end walls 23 and 24 and a dividing wall 25; a first coupling bar 26 which can be moved in the cylinder 22, which goes through the first end wall 23 and which is coupled to the driving means 8, whereby this coupling bar 26 is provided with a stop 27 which cooperates with a first side 28 of the dividing wall 25, whereby this stop 27 prevents the first coupling bar 26 from being pushed in the cylinder 22; a first compression spring 29 which is provided between the inside 30 of the first end wall 23 and a stop 31 on the first coupling bar 26; a second coupling bar 32 which can be moved in the cylinder 22 which goes through the second end wall 24 and which is connected to the rotatable element 6, whereby this coupling bar 32 is provided with a stop 33 which cooperates with the inside 34 of the second end wall 24, whereby this stop 33 prevents the second coupling bar 32 from sliding out of the cylinder 22; and a second compression spring 35 which is provided
  • the cylinder 22 is preferably composed of two cylinder parts 38 and 39 which are respectively provided between the end wall 23 and the dividing wall 25 on the one hand, and between the dividing wall 25 and the end wall 24 on the other hand, whereby the whole is held together by means of rods 40 which go through the walls 23, 24 and 25.
  • This interlock 41 preferably consists of a rotatable arm 42 with a first pawl 43 which can mesh in a recess 44 in the rotatable element 6 and a second pawl 45 which cooperates with the perimeter of a disc driven by the motor 13, in this case the above-mentioned disc 16, and which takes place in a recess 46 on the perimeter of this disc 16, whereby the interlock 41 is switched on when the second pawl 45 moves in the recess 46 of the disc 16.
  • the arm 42 is hereby forced into one direction by means of a spring 47.
  • the above-mentioned connection is hereby provided with a play 48 which allows for a rotation of the disc 16 over a small angle without the rotatable element 6 being moved, whereby this play 48 is so large that the interlock can be uncoupled during this rotation.
  • this play 48 can be obtained by using such a compression spring 29 or by mounting this compression spring 29 such that it allows for a free movement of the first coupling bar 26 in relation to the cylinder 22 over a certain distance D.
  • a slidable connecting piece 49 which retains the compression spring 29 and which is provided with a stop 50 which can cooperate with the stop 31.
  • the first coupling bar 26 can hereby move freely between a position in which the stop 27 makes contact with the side 28 and a position in which the stop 31 acts on the compression spring 29 through the intervention of the connecting piece 49.
  • the device 1 can be equipped with additional accessories.
  • a guide 54 which can be moved against the force of a spring 53 which makes sure that the conveyor element 2 is gradually slowed down via the drag pin 4 when it is uncoupled from the driving element 3.
  • the rotatable element 6 When an approaching conveyor element 2 must be uncoupled, the rotatable element 6 is maintained in the rest position A.
  • the drag pin 4 which is taken along by the drag chain then makes contact with the guiding edge 10 and is forced in the guide 7 as represented in figure 2.
  • the drag pin 4 As the drag pin 4 is situated outside the path of the drag chain, in particular of the protrusions 5, the drag movement is interrupted and the conveyor element comes to a standstill.
  • crank mechanism 4 In order to drag the conveyor element 2, the crank mechanism 4 is moved to and fro over one cycle by making the disc 16, via the control of the motor 13, make one rotation.
  • the first coupling bar 26 of figure 4 is shifted to the left, over the distance D, without following the cylinder 22 and the second coupling bar 32.
  • the rotatable element 6 keeps standing still during this movement.
  • the pawl 45 is forced out of the recess 46, the interlocking 41 comes loose.
  • the short standstill of the rotatable element 6 makes it possible to freely take the pawl 43 out of the recess 44.
  • the position of the figures 1 and 2 preferably forms the rest position, but that this is not necessarily so.
  • the motor 13 can be controlled in various manners. According to one possibility, use can be made of a servomotor which each time carries out a specific rotation. According to another possibility, an interruption contact can be provided on the arm 42.
