Definitions

  • the invention relates to packing machines, for example to machines for packing cigarettes.
  • the means for moving the push members generally comprise two endlessparallel conveyor chains linked together by transverse rods which carry the push members.
  • Conveyorfl chains as hitherto used comprise a multiplicity of beatings which are liable to wear and tear. If, for example, the distance between the two places through which the articles are to be conveyed is between 6 and '8 metres, then with commonly used conveyor chains 470 to 560 bearings may be required. When in use each bearing has been worn out by only 0.1 millimetre the total length of the conveyor chain is increased by 47 to 56 millimetres. This increase of length is sufiicient to upset the original setting of the machine and its correct functioning.
  • belts For transmitting power, belts have been used, which have teeth and are provided with pull-resisting inserts and a wear-resisting surface.
  • the pull-resisting inserts may comprise a plurality of steel cords, and the wear-resisting surfaces may be surfaces of layers of nylon on rubber or synthetic rubber.
  • Such belts are known per se and are at present available in the trade under the name Power Grip Belts. They have been used for transmitting power but, to the best of my knowledge have not been used as conveyor belts for packing machines.
  • FIG. 1 is a side view, partly in section, of a portion of an embodiment of the invention
  • FIG. 2 is a plan view of a portion of the embodiment of FIG. 1;
  • FIG. 3 is an end view, partly in section, of the embodiment of FIG. 1;
  • FIG. 4 illustrates a portion of a conveyor belt and a first clamp part of the embodiment of FIG. 1;
  • FIG. 5 illustrates a portion of a conveyor belt and a second clamp part of the embodiment of FIG. 1;
  • FIG. 6 illustrates the second clamp part of FIG. 5 separately.
  • FIG. 7 illustrates a portion of a toothed wheel of the embodiment of FIG. 1.
  • the embodiment illustrated comprises a feed table 10 for supporting articles 11.
  • the feed table 10 has a slot 12 extending in the longitudinal direction of the table 10. At each end, the slot 12 merges into a widened opening 121.
  • Push members 13 each having a head 14 for acting on articles 11 are provided, the push members 13 entering the slot 12 through the opening 121 at one end of the slot 12 and leaving the slot 12 through the other opening 121.
  • the push members 13 are movable by a conveyor arrangement underneath the table 10, the table 10 and the conveyor arrangement being mounted on support walls 16.
  • the conveyor arrangement comprises two pairs of toothed wheels 17, one pair shown in FIG. 3 being keyed to a common shaft 21 rotatably mounted in the support walls 16, and driven by any suitable drive 22, the other pair of toothed wheel 17 being idle and mounted on a similar shaft 211 parallel to the shaft 21 and rotatably mounted in the support walls 16.
  • gaps 18 FIG. 7
  • recesses 23 are provided which are tapering in a section perpendicular to the shaft 21.
  • Two Power Grip Belts 24 are provided, each belt 24 being entrained about two toothed wheels 17, one of each pair of toothed wheels. Each belt 24 (see FIGS.
  • the belts 24 are parallel to each other and to the slot 12 in the feed table 10, and lie at either side of the slot 12 symmetrically thereto.
  • Transverse elements in the shape of bars 28 are connected to the conveyor belts 24 and carry the push members 13 which thus are linked to the conveyor belts 24.
  • the push members 13 are bolted to the transverse bars 28 by bolts 15 and are movable with the conveyor belts 24.
  • the transverse bars 28 are provided with rounded elements 31, at their ends, the centre of curvature of the elements 31 lying in the axis of the shaft 21 or 211 while a transverse bar travels with the respective toothed Wheels 17 around the respective shaft.
  • the rounded end elements 31 of the transverse bars 28 are guided in channels 32 provided in guide members 33. At each end, the channels 32 widen as at 34 and lead to circular guide channels 35 adjacent the peripheries of the toothed wheels 17, the circular guide channels 35 being formed by guide plates 36 carried by the support walls 16.
  • the transverse bars 28 are connected to each belt 24 by means of a two-part clamp illustrated in FIGS. 4, 5 and 6.
  • Each clamp comprises two-H-shaped clamp parts 37 and 38, the belt 24 being sandwiched between transverse portions 41 and 42 of the H-shaped clamp parts 37 and 38.
  • the length of the transverse portions 41 and 42 is at least equal to the width of the belt 24 so that longitudinal portions 43 and 44 of the H-shaped clamp parts 37 and 38 lie beyond the belt 24 and can be bolted together by means of bolts 45 extending through holes 46 in the clamp part 37 and being screwed into screwthreaded holes 47 in the clamp part 38.
  • the bolts 45 also extend through holes in the transverse bars 28 near their ends and thus connect the transverse bars 28 to the belts 24.
  • the clamp parts 37 and 38 are tightly clamped to the belt 24 by the bolts 45, the said bolts do not penetrate through the belt 24 but lie at both sides of the belt 24. Thereby any weakening of the belt 24 by bolts penetrating through the belt is avoided.
  • the clamp part 37 acts as a spacer between the respective transverse bar 28 and the belt 24.
  • the transverse portion 42 of the clamp part 38 is conical insection perpendicular to the axis of the shafts 21 and 211 as can best be seen from FIG. 1.
  • the clamps are so located on the belts 24, that the conical portions 42 of the clamp parts 38 are received in the conical recesses 23 of the toothed wheels 17 while the respective clamp travels with a toothed wheel 17 about its shaft 21 or 211.
  • Brushes 48 are provided for cleaning the teeth gaps 18 and recesses 23 of the toothed wheels 17.
  • the toothed Wheels 17 are covered at their sides by discs 51.
  • the toothed wheels 17 keyed to the shaft 21 are rotated by the drive 22. .Thereby the belts 24 travel in the direction of the arrow A in FIG. 1, and'cause the push members 13 fixed to the transverse bars 28 to penetrate the slot 12 in the table through the .widened opening 121 at one end ofthe 'slot 12 to travel along said slot 12 while pushing an article 11 forward along the table 10, and to leave the slot 12 through the'widened opening 121 at the other end of the slot '11.
  • the transverse bars 28 being guided by the channels 32 and by the circular guide channels 35.
  • any bolts, screws or like means for connecting the transverse bars 28 to the belts 24 and which would penetrate the belts 24 and may damage and weaken the same are avoided.
  • the transverse bars 28 By spacing the transverse bars 28 from the belts 24 by means of the clamp portions 37 it is achieved that any dirt or dust which may in use be deposited in such spacing may fall out therefrom under the action of gravity while the belt 24 travels in an upwards or downwards direction. If the transverse bars 28 would be mounted tight against the belts 24, a temporary gap between the bars 28 and'the adjacent surfaces of the belts 24 would, nevertheless, be formed while the bars 28 travel with the toothed wheels 17 in a curved path.
  • the belts 24 do not require any lubrication or any adjustment owing to wear and tear.
  • the brushes 48 which if desired may be omitted, serve to keep clean the teeth, the gaps 18 and the recesses 23 of the toothed wheels 17.
  • a conveyor arrangement comprising a plurality of members for conveying articles from one placev to another, two endless parallel pull-resisting conveyor belts, a plurality of elements extending transversely to said conveyor belts, each transverse element carryingone of said conveying members, means for clamping each of said transverse elements to said conveyor belts and for distancing said transverse elements from said belts, teeth provided on each conveyor belt, toothed wheels for driving said conveyor belts, and teeth on said toothed wheels, said teeth of said toothed Wheels being' complementary to and meshing with teeth on said belts, wherein said clamping means each comprise a first H-shaped clamping part at one side of a conveyor belt, a second H-shaped clamping part at the other side of said conveyor belt, each H-shaped clamping part having parallel longitudinal portions and a transverse portion between said longitudinal portions, the length of said, transverse portion being at least equal to the width of said conveyor belt, said transverse portion of said second clamp part being adapted to engage
  • transverse portion of said second clamping part tapers in cross-section perpendicular to said transverse portion for adapting said transverse portion to be received in a recess provided in' a gap between teeth of said toothed wheels, said recess being complementarily tapering.
