Definitions

  • the present invention relates to a tray conveyor for glass products in a continuous thermal treatment furnace.
  • Furnaces for the continuous thermal treatment of glass containers using a conveyor are already known, for example from patent EP0960863B1.
  • the conveyors described in said patent include crosspieces on which the glass containers are tidily positioned so that an automatic handler can pick them after the thermal treatments occurring in the furnace and in a ventilated cooling zone.
  • the crosspieces of said patent are provided with seats identified by two supports in correspondence with the ends of each glass container which stabilizes the position thereof and prevents damage to the screen-printing or other type of printing.
  • the conveyor crosspieces of this patent are associated with brackets facing the interior of the conveyor chains and overhangingly fixed therewith.
  • Said assembly operation allows the crosspieces to move jointly with the chain, thus minimizing the dimensions of the conveyor in a manner deemed advantageous by most.
  • the operations of disassembling and reassembling the crosspieces are difficult for routine maintenance of the conveyor and for changing the products to be made in series.
  • said object is achieved by a conveyor for a thermal treatment furnace for glass products comprising at least one pair of parallel chains adapted to feed a plurality of trays interposed between the parallel chains, characterized in that said trays comprise at least two openings on opposite ends thereof adapted to be inserted above vertical members of the chains.
  • Figure 1 is a perspective view of a continuous thermal treatment furnace fitting a tray conveyor for glass products according to the present invention
  • Figure 2 is a side view of the furnace in Figure 1 ;
  • Figure 3 is a perspective view of the conveyor of the furnace in Figure 1;
  • Figure 4 is a side view of the conveyor in Figure 3;
  • Figure 5 is a top plan view of the conveyor in Figure 3;
  • Figure 6 is a section view taken along line VI- VI in Figure 5 ;
  • Figure 7 is a plan top view of a portion of Figure 5 on which some trays with glass products are mounted in working position;
  • Figure 8 is a partial section view taken along line VIII- VIII in Figure
  • Figure 9 is a side view of a portion of the conveyor in Figure 7;
  • Figure 10 is a perspective view of a portion of the conveyor in Figure 7;
  • Figure 11 is a top plan view of a portion of the conveyor on which alternative trays are mounted with glass products in working position, having alternative shape and size as compared to that in Figure 7;
  • Figure 12 is a perspective view of the tray in Figure 7;
  • Figure 13 is a side view of the tray in Figure 13;
  • Figure 14 is a top plan view of the tray in Figure 13;
  • Figure 15 is a front view of the tray in Figure 13;
  • Figure 16 is a perspective view of the alternative tray in Figure 12 for products of different shape and size;
  • Figure 17 is a perspective view of an alternative tray with products of different shape and size arranged on two rows.
  • a conveyor 5 which runs in a hot zone 6 and in a ventilated zone 7 of a furnace 9 for the continuous thermal treatment of glass products 100 of different shape and size with screen-printing or printing of different type, which are removed from the conveyor 5 itself at the end of the thermal treatment by a mechanical handler 8.
  • Conveyor 5 comprises a sequence of trays 1, the ends 35, 36 of which are inserted from the top through two openings 38, 39 above respective vertical members 26 of two parallel opposite chains 25.
  • Openings 38 and 39 have reciprocally different size. Opening 38 is appropriately wider than opening 39 to promote thermal expansion. Opening 39 is instead adapted to work as a reference for the position of tray 1.
  • Trays 1 comprise U-shaped lock fastening bolts 27 in correspondence with the openings 38, 39 which fix them to the vertical members 26 of chains 25 by means of fastening rivets 28.
  • Tray 1 comprises an upper vertical sheet 10 folded upwards so as to be perpendicular to a horizontal surface 30, as shown in figure 13. Said upper vertical sheet 10 supports one of the two ends of the glass products 100. With this regard, upper compartments 11 are obtained on sheet 10 in sequence and appropriately spaced apart according to the size of the products 100 themselves.
  • Tray 1 also comprises a lower vertical sheet 20 folded downwards so as to be perpendicular to a horizontal surface 30, are shown in figure 13. Said lower vertical sheet 20 advantageously works instead as a counterweight for the structure of trays 1 so as to balance the forces acting on the structure of conveyor 5.
  • Trays 1 accommodate a plurality of lower compartments 31 parallel to one another along the motion direction of conveyor 5, on the horizontal surface 30 thereof in correspondence with the upper compartments 11. Said lower compartments 31 are obtained on the upper surface 30 by means of two fins 32 and 33 advantageously folded downwards to obtain a recess for supporting one of the two ends of a glass product 100.
  • the arrangement of the lower compartments 31 advantageously allows conveyor 5 to move at a faster speed than the conveyors known in the prior art, because the rolling movement of conveyor 5 is distributed along the vertical axis of the glass products 100 thus greatly reducing the likelihood of making them roll out from the lower 31 and upper 11 compartments and preventing damage to the printing. Furthermore, the direction of the lower compartments 31 advantageously allows a higher speed in positioning the glass products 100 on trays 1, because the possibility of the containers 100 rolling out from the lower compartments 31 is reduced.
  • trays 1 comprise a plurality of holes 37 on the horizontal surface 30 thereof, a plurality of holes 12 on the vertical sheet 10 and a further plurality of holes 21 on the vertical counterweight sheet 20.
  • Trays 1 are carried by chains 25 which are meshed on four pairs of toothed wheels 51, 53.
  • Each of said pairs of toothed wheels 51, 53 has a shaft 55 which allows a rotational association with supports 93 associated in turn with furnace 9.
  • the first pair of said toothed wheels 51 is positioned on the upper ends of conveyor 5 and the other pair of toothed wheels 53 is positioned on the lower ends of the conveyor 5 itself.
  • At least one rotary motor is rotationally associated with at least one of the four pairs of toothed wheels 51, 53 to allow the trays 1 of conveyor 5 to slide.
  • Trays 1 are supported by two parallel, opposite upper roller beds 41 including a plurality of wheels 43, the upper part of which is engaged in contact with a portion of a lower surface 34 of trays 1, thus supporting them.
  • the upper roller beds 41 comprise a supporting member 44 which rotationally mounts and protects the wheels 43, and also protects the chain 25, as shown in figure 8. Said support 44 is fitted on furnace 9 by means of sheets 95.
  • Trays 1 are supported on the lower part of conveyor 5 by two lower roller beds 42 similar to the upper ones 41.
  • the supporting structure 44 of the lower roller beds 42 rotationally mounts a plurality of wheels 43, the upper part of which is engaged in contact with a portion of an upper surface 30 of trays 1, thus supporting them, as shown in figure 6.
  • the advantage of the lower roller bed 42 is to improve the support and sliding movement of trays 1 in the lower return segment of conveyor 5.
  • the lack of the lower roller bed 42 results in the blockage of the conveyor 5, thus causing machine stops due to the releasing of the brackets from the known crosspieces, with consequent blockage of the chains 25.
  • the huge advantage of positioning the trays 1 above vertical members 26 of the chains 25 facilitates and speeds up the operations of disassembling and reassembling trays 1 for routine maintenance of the conveyor 5 and for changing the products 100 to be produced in series, because only the U- shaped lock fastening bolts 27 need to be removed in order to remove trays 1.
  • Another advantage due to the ease and speed of even disassembling a single tray 1 from its seat, is that of being able to fit different types of trays 1 as desired, thus responding to the need for maximizing the number of products 100 on each single tray 1 and promoting a higher production of products 100 in less time.
  • Said assembly operation from the top advantageously reduces the effects of torsion forces which, in the prior art, mainly acted on the brackets extending horizontally from the ends of the known horizontal crosspieces towards the interior of the chains.
  • the positioning of the trays 1 of the present invention allows to advantageously reduce the risk of breakage of chains 25.
  • trays 2 are provided with a higher number of upper 11 and lower 31 compartments so as to meet the needs of alternative glass products 101 of different shape and size as shown in figure 16.
  • Two upper vertical sheets 10 and two lower counterweight sheets 20 for each tray 1 can be provided, so as to alternately arrange the ends of the glass products 100 advantageously occupying the smaller space or alternatively increasing the number of products 100 for each tray 1.
  • Trays 1 with two upper vertical sheets 10 are also provided to arrange the products 100 on two rows, thus allowing the size of tray 1 to be advantageously reduced, as shown in figure 17. This solution allows to contain the total length of furnace 9 and to obtain a considerable energy saving.
