Fig. 9 is a perspective view of a box handling apparatus used in the process.
Referring to the drawings, at a mixer 10, a biscuit dough is prepared from selected ingredient materials. The biscuit dough is delivered to a dough handling apparatus 12 in which the dough is divided into a plurality of dough pieces of a desired shape. Each of the dough pieces is delivered onto a conveyor for carriage through an oven 14 . Within the oven 14, the dough pieces are cooked to form biscuits .
Biscuits discharged from the oven 14 are cooled 16 prior to delivery of the biscuits to a wrapping station 18 in which the biscuits are encased in sealed wrappers forming packs of biscuits. Each pack of biscuits contains a selected number of biscuits required to achieve a desired weight of biscuit pack.
Downstream of the wrapping station 18, each pack of biscuits is checked on a weigher 20 to ensure the pack has a minimum desired weight. The biscuits are discharged from the weigher 20 on a transfer conveyor 21. Immediately downstream of the weigher 20, on opposite sides of the transfer conveyor 21, there is provide a set of air jets 22 and an associated reject bin 23. The air jets 22 are normally off. A controller for air supply to the air jets 22 is connected to the weigher 20 so that if an underweight pack of biscuits is detected by the weigher 20, the air jets 22 are operated to blow the pack off the conveyor 21 into the reject bin 23.
- 5 Next, each pack of biscuits travels on the conveyor 21 passed a metal detector 25. Should the metal detector 25 detect the presence of metal within a pack of biscuits, an arm 26 pivoted at 27 swings outwardly across the conveyor 21 to positively block the travel of biscuit packs on the conveyor 21 and deflect the pack of biscuits into a second reject bin 28.
The packs of biscuits are then delivered in an axial direction along a separator 29 comprising a set of three feed conveyors 30, 31, 32. These feed conveyors 30, 31, 32 are arranged such that the speed of a first feed conveyor 30 is faster than the transfer conveyor 21. A second feed conveyor 31 is travelling faster than the first feed conveyor 30 and the third feed conveyor 32 is travelling faster than the second feed conveyor 31. In this way, the packs of biscuits are spaced-apart a minimum desirable preset distance prior to delivery to a packing machine 35.
A spacing sensor 36 checks the spacing between the packs of biscuits, and if not sufficient the packs of biscuits, the packs of biscuits are blown by air jets 37 at one side of the third feed conveyor 32 into a collection bin 38 at an opposite side of the third feed conveyor 32.
At an outlet end 39 of the third feed conveyor 32, each pack of biscuits is fed into one of a number of associated pockets 40 in a pick-up conveyor 41 which travels at right angles to the third feed conveyor 32. In this case, a set of six associated pockets 40 are provided. Each pocket 40 is filled in turn. The first pocket 40 aligns with the outlet end 39 of the third feed conveyor 32 to receive a pack of biscuits. Then the pockets 40 move to align the second pocket 40 with the outlet end 39 of the third feed conveyor 32 and so on until all six pockets are filled
- 6 with a pack of biscuits. The set of six filled pockets 40 are then delivered to a loading station 45.
At the loading station 45, a movable arm 46 with a pickup head 47 locates above the packs of biscuits in the pockets 40. The pick-up head 47 has a set of suction cups which engage and grip each of the packs of biscuits within the set of pockets 40. The arm 46 then is raised and is moved over a box 49 on an adjacent transfer conveyor 50, the box being stationary, and lowered into the box 49 to deposit the packs of biscuits within the box 49. With the suction cups released, the arm 46 is retracted to pick up another set of packs of biscuits for delivery into the box 49. In this way, a number of layers of packs of biscuits are built up in the box 49 to fill the box 49.
Filled boxes 49 are delivered on transfer conveyors 50, 51, 52 to a palletising station 53 where a number of the boxes are built up on pallets.
A magazine 55 of blanks 56 for forming the boxes 49 is provided at one end of the conveyor 50. As a filled box 49 is discharged from the loading station 45, a blank is fed from the magazine 55, assembled into an open-topped box 49 and positioned at the loading station 45 for reception of packs of biscuits.
It will be noted that a sensor 60 is provided at the outlet end 39 of the third feed conveyor 32 to detect the presence of a pack of biscuits at the outlet end 39 of the feed conveyor 32. The sensor 60 is connected to a controller for the pick-up conveyor 41 which incrementally aligns the pockets 40 in turn with the outlet end 39 of the third feed conveyor 32. Movement of the pick-up conveyor 41 can only occur to correctly align an empty pocket 40 with the outlet end 39 of the conveyor 32 if no
- 7 pack of biscuits is detected at the outlet end 39. Otherwise, the packing machine 35 stops and the air jets 37 operate to prevent further feeding of packs of biscuits to the pick-up conveyor 41. It will also be noted that a further set of emergency air jets 65 are provided at an outlet end of the transfer conveyor 21 for blowing packs of biscuits into a collecting bin 66 in the event of shutdown of the packing machine 35.
The invention provides a process and apparatus for the efficient production of a high quality biscuit product. It will be noted that each of the pockets on the pick-up conveyor is adapted for handling a number of different sizes of packs of biscuits. Each pocket has arcuate side walls forming a U-shaped cradle which will receive and support biscuit packs of different diameter. Thus conveniently a range of different products can be produced.
Conveniently all the packs of biscuits are arranged in the box in the same orientation.
It will be noted that the spacing of the biscuit packs on the feed conveyors is critical for the correct feed of the biscuit packs into the pockets of the pick-up conveyor. Advantageously, if the spacing between an adjacent pair of packs of biscuits is not correct, the down-stream pack of biscuits is simply removed from the production line by the airjets so as not to interrupt the flow of packs of biscuits through the packing machine.
The invention is not limited to the embodiments hereinbefore described which may be varied in both construction and detail.
