Description
- The present invention relates to an apparatus for feeding flat products to a machine.
- More precisely, the invention relates to an apparatus that carries out the processing operation connecting a system for manufacturing products such as biscuits or crispbread to a machine comprising a device which forms groups of said products and feeds said groups to a receiving line.
- According to the known art, products of the above-mentioned type exiting continuously from a cooking oven are fed directly into said apparatus. Said apparatus is constituted by a plurality of conveyance devices, each of which is constituted by at least two conveyor belts arranged in series and driven with speeds which increase along the direction of product advancement.
- The products advance in continuous rows on these conveyance devices and are packed flat against each other and oriented edgeways on their respective advancement surfaces.
- At the output ends of the conveyance devices, the products are divided into groups which are fed to a receiving line which in turn feeds said groups to a packaging or boxing machine. A device for forming said groups and for feeding them to said receiving line is described in European Patent No. 0 161 110.
- A condition for the correct operation and the high productivity of a system comprising machines and devices of the above-mentioned type is that the products must be arranged correctly, i.e. packed flat against each other and oriented edgeways on their respective conveyance devices, at the output of every conveyance device of said apparatus and therefore at the input of the group forming device.
- In this kind of apparatus, it is observed that the unavoidable imbalances between the number of products fed onto the individual conveyance devices and the number of products removed therefrom cause gaps in the otherwise continuous row of products. Due to these problems, the products closest to the gaps tip over onto the conveyor.
- These products arranged face-down must be removed manually by the operator, since they are the main cause of the forming of defective or incomplete groups at the output ends of the conveyance devices being that they hinder the re-establishment of the continuity of the row.
- US-A-508 092 discloses a cracker stacking machine which comprises an endless feeding belt for feeding crackers arranged thereon in loose form to a longitudinal receiving table arranged at a downwardly inclined angle in the direction of feeding. The receiving table is provided with a reciprocating motion in the direction of feeding, and rigidly connected to such table is a receiver which is upwardly provided with a series of concave-shaped troughs. Arranged between the endless belt and the receiving table is an inclined platform provided with forward tongue portions which are accommodated in respective troughs which guidingly receive the crackers therefrom.
- The aim of the present invention is to provide a feeding apparatus of the above-mentioned type which eliminates the described disadvantages relative to the known art, i.e. an apparatus which feeds to a group forming device a continuous row of products packed flat against each other and oriented edgeways on their respective conveyance device.
- This aim is achieved by an apparatus for feeding flat products as defined in the appended
claim 1. - The present invention is now described merely by way of non-limitative example with reference to the accompanying drawings, wherein:
- figure 1 is a schematic elevation view of a system comprising a feeding apparatus according to the teachings of the present invention;
- figures 2 and 3 are two sectional views of the vibrating channels of the apparatus of figure 1.
- With reference to figure 1, the
reference numeral 1 indicates an overall system for manufacturing and handling flat products such as biscuits or crispbread. - Said
system 1 comprises afeeder apparatus 2 suitable for connecting aunit 3 for producing said products to a machine 4 comprising a device (not illustrated) for forming groups each constituted by a given number of products. Theapparatus 2 consists of aconveyance device 5 inclined in the direction of advancement of the products conveyed thereby and comprising afirst conveyor belt 6 for the output of theproduction unit 3, asecond conveyor belt 7 arranged after theconveyor belt 6 with respect to the product advancement direction, a first vibratingchannel 8 interposed between theconveyor belts vibrator device 9, and a second vibratingchannel 10 interposed between theconveyor belt 7 and said machine 4 and actuated by avibrator device 11. Theconveyance device 5 is suitable for transferring said products packed flat against each other and oriented edgeways with respect to the conveyance surface. - Figures 2 and 3
show channels channels base wall 14 and twolateral walls 15, and their dimensions are such that they adhere for a set portion to the contour of the products 13. - The
base wall 14 of thechannel 8 has a plurality ofsteps 16 descending in the direction of advancement of the products 13 along theconveyance device 5. The height ofsaid steps 16 is just in excess of the thickness of the products 13 and their width is substantially equal to the height of said products 13. - In operation the products 12 or 13 are transferred by the
conveyance device 5 while packed flat against each other and oriented edgeways on the conveyance surface. Due to the unavoidable imbalances between the number of products supplied by theproduction unit 3 and the number of products removed by the machine 4 the continuity of the row is occasionally broken, so that some products 12 or 13 tip over and arrange themselves substantially horizontally. - Every time a product 13 arranges itself substantially horizontal in contact with the
base wall 14, the step-like configuration of the vibratingchannel 8 and the dimensions of thesteps 16 aid said product 13 in resuming its vertical position. In fact, according to what is illustrated in particular in figure 2, the fallen products 13 tend to progressively resume their correct substantially vertical position as soon as one of their ends makes contact with a vertical oriented product 13 preceding them along the conveyance path with no jamming due to the level difference between thesuccessive steps 16. - In this manner, the continuous row of products packed against each other and oriented edgeways with respect to the resting surface of the
conveyance device 5 is reconstituted allowing said device (not illustrated) for forming groups of products to operate correctly.
