It is known that for coupling and/or uncoupling conveyor elements in relation to the driving mechanism, use can be made of an element which can be rotated by means of driving means in which is provided a guide for a drag pin of a conveyor element, such that a conveyor element, due to the rotation of the rotatable element so as to place it in a given angular position, can be uncoupled from and/or coupled to the drag device, as the drag pin is either put out of the path followed by the driving mechanism, or is put back into this path by means of the above-mentioned guide. - However, 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.

- According to a preferred embodiment, the above-mentioned means consist of an elastic, deformable connection. The connection hereby preferably offers some initial resistance against the deformation, which is so great that a deformation only occurs when there is a jam.
- In a constructional simple embodiment, the abovementioned connection will consist of axially slidable parts in between which are provided springs.
- The above-mentioned 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.
- Preferably, however, in order to optimally exclude damages, the device will be designed double-acting, such that the connection can give way 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.
- In order to better explain the characteristics of the invention, the following preferred embodiment is described as an example only without being limitative in any way, with reference to the accompanying drawings, in which:
- figure 1 shows a top view of a device according to the invention, whereby a part of a conveyor element is also represented;
- figures 2 and 3 show the device from figure 1 in other positions, however without the conveyor element being represented;
- figure 4 shows a section of the part which is indicated in figure 1 with F4 to a larger scale.
-
- As represented in figure 1, the invention concerns a
device 1 for uncoupling and/or coupling conveyor elements 2, such as a trolley, in relation to a driving mechanism, in particular adriving element 3 thereof, such as a drag chain. - As is known, the conveyor element 2 can hereby be moved by means of a
drag pin 4 or such. Thedrag pin 4 can hereby be taken along by aprotrusion 5 provided on thedriving element 3. - The above-mentioned
device 1 for coupling and/or uncoupling the conveyor elements 2 in relation to thedriving element 3 consists of arotatable element 6 in which is provided aguide 7 for adrag pin 4 of a conveyor element 2 and driving means 8 to rotate therotatable element 6, such that a conveyor element 2 can be uncoupled from and/or coupled to the drivingelement 3 by turning therotatable element 6 and by putting it in a given angular position. - The
rotatable element 6 can have various forms, but it preferably consists of a disc which can rotate around apivot 9, whereas theguide 7 provided in it consists of a recess which is confined by two guidingedges - When the disc is in a first position A, as represented in the figures 1 and 2, the guiding
edge 10 stretches such that thedrag pin 4 of an approaching conveyor element 2 is guided outside the path of thedriving element 3 according to the course X represented in figure 2. - By rotating the
rotatable element 6 into a position B, as represented in figure 3, theguiding edge 11 makes sure that thedrag pin 4 is forced back into the path of thedriving element 3 over afixed guide 12. - In the example represented, the above-mentioned driving means 8 consist of an
electric motor 13 and acrank mechanism 14 which is driven by themotor 13 and which converts the rotating movement R in a to and fro rocking motion T of therotatable element 6. Thiscrank mechanism 14 may for example consist of a crank rotating around apivot 15, in the shape of adisc 16 which is driven by themotor 13 via agear transmission 17, and a connectingrod 18 which is connected to thedisc 16 by means of apivot 19 on the one hand, and which is connected to therotatable element 6 by means of apivot 20 on the other hand. - According to the invention, means 21 are provided between the driving means 8 and the
rotatable element 6 which can give way when therotatable element 6 jams. - In the example represented, 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. - As described in the introduction, these means 21 preferably consist of an elastic, deformable connection, in this case between the
pivots device 1 functions normally, there is no or almost no deformation and the distance between thepivots 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. - As represented in figure 4, the above-mentioned elastic, deformable connection preferably consists of a
cylinder 22 with twoend walls wall 25; afirst coupling bar 26 which can be moved in thecylinder 22, which goes through thefirst end wall 23 and which is coupled to the driving means 8, whereby thiscoupling bar 26 is provided with astop 27 which cooperates with afirst side 28 of the dividingwall 25, whereby thisstop 27 prevents thefirst coupling bar 26 from being pushed in thecylinder 22; afirst compression spring 29 which is provided between theinside 30 of thefirst end wall 23 and astop 31 on thefirst coupling bar 26; asecond coupling bar 32 which can be moved in thecylinder 22 which goes through thesecond end wall 24 and which is connected to therotatable element 6, whereby thiscoupling bar 32 is provided with astop 33 which cooperates with theinside 34 of thesecond end wall 24, whereby thisstop 33 prevents thesecond coupling bar 32 from sliding out of thecylinder 22; and asecond compression spring 35 which is provided between thesecond side 36 of the dividingwall 25 and astop 37 on thesecond coupling bar 32. - In order to obtain a constructional simple design, the
cylinder 22 is preferably composed of twocylinder parts end wall 23 and the dividingwall 25 on the one hand, and between the dividingwall 25 and theend wall 24 on the other hand, whereby the whole is held together by means ofrods 40 which go through thewalls - The
device 1 can possibly be equipped with amechanical interlock 41 which can interlock therotatable element 6 in the above-mentioned position A in order to prevent theelement 6 from turning when adrag pin 4 slides along the guidingedge 10. - This
interlock 41 preferably consists of arotatable arm 42 with afirst pawl 43 which can mesh in arecess 44 in therotatable element 6 and asecond pawl 45 which cooperates with the perimeter of a disc driven by themotor 13, in this case the above-mentioneddisc 16, and which takes place in arecess 46 on the perimeter of thisdisc 16, whereby theinterlock 41 is switched on when thesecond pawl 45 moves in therecess 46 of thedisc 16. Thearm 42 is hereby forced into one direction by means of aspring 47. - According to the invention, the above-mentioned connection is hereby provided with a
play 48 which allows for a rotation of thedisc 16 over a small angle without therotatable element 6 being moved, whereby thisplay 48 is so large that the interlock can be uncoupled during this rotation. As represented in figure 4, thisplay 48 can be obtained by using such acompression spring 29 or by mounting thiscompression spring 29 such that it allows for a free movement of thefirst coupling bar 26 in relation to thecylinder 22 over a certain distance D. In the example represented, use is made to this end of a slidable connectingpiece 49 which retains thecompression spring 29 and which is provided with astop 50 which can cooperate with thestop 31. Thefirst coupling bar 26 can hereby move freely between a position in which thestop 27 makes contact with theside 28 and a position in which thestop 31 acts on thecompression spring 29 through the intervention of the connectingpiece 49. - It is clear that the
device 1 can be equipped with additional accessories. - Depending on the way in which the
device 1 must be controlled, use can be made for example of detectors and/or an encoder which are not represented in the drawings to determine the position of thedisc 16. - Further, use can be made of a
guide 54 which can be moved against the force of aspring 53 which makes sure that the conveyor element 2 is gradually slowed down via thedrag pin 4 when it is uncoupled from thedriving element 3. - The working of the
device 1 can be derived from the accompanying drawings and is mainly as follows. - When an approaching conveyor element 2 must be uncoupled, the
rotatable element 6 is maintained in the rest position A. Thedrag pin 4 which is taken along by the drag chain then makes contact with the guidingedge 10 and is forced in theguide 7 as represented in figure 2. As thedrag pin 4 is situated outside the path of the drag chain, in particular of theprotrusions 5, the drag movement is interrupted and the conveyor element comes to a standstill. - In order to drag the conveyor element 2, the
crank mechanism 4 is moved to and from over one cycle by making thedisc 16, via the control of themotor 13, make one rotation. - First, the
first coupling bar 26 of figure 4 is shifted to the left, over the distance D, without following thecylinder 22 and thesecond coupling bar 32. Therotatable element 6 keeps standing still during this movement. As thepawl 45 is forced out of therecess 46, the interlocking 41 comes loose. The short standstill of therotatable element 6 makes it possible to freely take thepawl 43 out of therecess 44. - As the
crank 16 is moved further, thestop 31 makes contact with thestop 50. Since thespring 29 will only be compressed under abnormally large forces, thecylinder 22 and thecoupling bar 32 are drawn along, so that therotatable element 6 is brought in the position B of figure 3 and the above-mentioneddrag pin 4 is brought back in the path of thedriving element 3, and consequently is taken along by thisdriving element 3. - As the
crank 16 is moved still further, therotatable element 6 is turned back in the position A. - When the
rotatable element 6 jams, for any reason whatsoever, for example because adrag pin 4 becomes locked in an abnormal way between theelement 6 and another part of the device, the security device is activated, which implies that themotor 13 can continue to work normally without the disadvantages occurring as mentioned in the introduction. In a concrete manner, this means that, in the example represented, thespring 29 will be compressed when theelement 6 is jammed as the connectingrod 18 moves to the left, and that thespring 35 will be compressed when theelement 6 is jammed as the connectingrod 18 moves to the right, so that in both cases thepivot 19 can move, whereas thepivot 20 stands still. - It should be noted that the position of the figures 1 and 2 preferably forms the rest position, but that this is not necessarily so. In order to obtain that the driving means 8 are always stopped in the rest position, 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 thearm 42. - The present invention is by no means limited to the embodiment described as an example and represented in the drawings; on the contrary, such a device for uncoupling and/or coupling a conveyor element 2 in relation to a drag mechanism can be made in various forms and dimensions while still remaining within the scope of the invention.
