Abstract
Description
- The present invention relates to an apparatus for wrapping delicate products, particularly such as soap bars.
- As is known, at the output of molding machines, soap bars are mutually spaced by a constant pitch and are then deposited in seats of a conveyor which feeds them towards a wrapping machine.
- A wrapping machine is essentially constituted by a flexible element which is aligned with the soap bar feeder conveyor and on which equidistant clamps are arranged; said clamps pick up the wrapping sheets from a feeder unit and place them horizontally above each incoming soap bar. After the placement of the wrapping sheets on the soap bars, appropriate folding elements close the wrapping. A wrapping machine of this type is described for example in Italian patent no. 906563.
- Apart from a considerable structural complexity, wrapping machines of the described type have the substantial disadvantage that the distance between the clamps is excessive and cannot be reduced due to constructive reasons, so that problems in timing with respect to the incoming soap bars arise; these problems in practice lead to a reduction in the processing rate and, ultimately, to the impossibility of fully exploiting the potential of the molding machine.
- The technical aim of the present invention is therefore to provide an apparatus for wrapping delicate products, particularly a wrapping machine for soap bars, which allows to obviate the shortcomings peculiar to conventional machines, i.e. is less complicated and faster.
- This aim is achieved by an apparatus for wrapping delicate products, particularly such as soap bars, which comprises: a product feeder conveyor which is provided with equidistant seats for receiving the individual products; a transfer unit which is closed in a loop and has an initial portion which is aligned with, and superimposed on, the terminal portion of said feeder conveyor; a plurality of clamp elements which are mounted on said transfer unit at a mutual distance equal to the distance between the products on said conveyor; said conveyor and said transfer unit having an equal speed and being mutually in step so that along said overlapping portions a product is arranged opposite to each clamp; an abutment arranged at each clamp element; means for feeding wrapping sheets; means for placing each wrapping sheet under a respective abutment; means for lifting the individual products from their respective seats towards the opposite abutments, so that each wrapping sheet remains secured between a product and the related abutment; means for actuating said clamp elements so as to wrap and grip said products and transfer them towards folding elements to complete the wrapping; said apparatus being characterized in that said wrapping sheet placement means comprise a sheet insertion device which extends toward the point of tangency between said conveyor and said transfer unit, said insertion device being adapted to insert the wrapping sheets between each product and the opposite abutment so that each sheet has a flap in front of the respective product and one behind said product when it is secured between a product and the opposite abutment.
- Further peculiarities of the invention will become apparent from the following description of a preferred embodiment, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- figure 1 is a partially schematic lateral elevation view of the apparatus;
- figure 2 is an enlarged-scale view of a detail of figure 1;
- figure 3 is a view of the apparatus of figures 1 and 2 directly associated with a soap bar molding machine.
- With reference to the above figures, the apparatus comprises a
conveyor 1 for feeding theproducts 2, which in the specific case are constituted by soap bars which arrive from amolding machine 3 with which the apparatus is associated. Conveniently, said molding machine is provided with a soap bar unloading system according to Italian patent no. 1,215,811 in the name of the same Applicant. - The
conveyor 1 is composed of a flexible element 4 (for example a pair of chains or belts) which has a horizontal upper section with aterminal portion 5 which moves in the direction A. - Seats 6 for the
soap bars 2 are distributed with a pitch P along theconveyor 1; each seat is formed by a pair ofwings 7 and 8 which are articulated to theflexible element 4 and are shaped so as to accommodate thesoap bars 2 arriving from themolding machine 3 and keep them in position. Along the upper section of the flexible element, thewings 7 and 8 are kept upright by means of stationary cams (not shown) so as to form the seats 6. At the end of the upper section, proximate to thepulleys 9 for guiding theflexible element 4, the cams open thewings 7 and 8 to release the soap bars and allow their further advancement by means of a transfer unit, generally designated by thereference numeral 10. - Said
transfer unit 10, too, is constituted by a flexible element 11 (for example chains or belts) which is wound in a loop around twopulleys conveyor 1. Thetransfer unit 10 comprises a lower section which is parallel to the upper section of theconveyor 1 and has aninitial portion 14 which overlaps theterminal portion 5 of theconveyor 1. - The
transfer unit 10 and theconveyor 1 are actuated with identical and opposite speeds, so that their lower and upper sections move with nil relative speed in the same direction A. - A plurality of
clamp elements 15 is distributed along theflexible element 11; clamp each element is composed of a pair of articulatedjaws abutments 18 are arranged. - The
clamp elements 15 have the same pitch P as the seats 6, and theconveyor 1 is in step with thetransfer unit 10 so that arespective clamp element 15 is vertically aligned along the overlappingportions - It should be noted that the
abutments 18 are arranged at a slightly higher level than the top of thesoap bars 2, so that a gap is left between the soap bars and the abutments; due to reasons specified hereinafter, this gap is recovered by lifting the soap bars from their location within the seats 6 against theabutments 18. - For this purpose there is a third
flexible element 19 which is closed in a loop and extends in the same direction and at the same speed as theconveyor 1. - Said
element 19 is wound around a pulley which is coaxial to thepulleys 9 and around apulley 20 which is supported ahead of the point B at which theflexible element 11 of thetransfer unit 10 arranges itself parallel to theflexible element 4 of theconveyor 1. -
Elastic supports 21 are distributed on theflexible element 19, have the same pitch as the seats 6 and are in step with them. Saidflexible element 19 is timed and guided so as to move thesupports 21 below therespective soap bars 2 and then raise them by means of stationary cams (not shown) until contact is made with theabutments 18 of theclamp elements 15. - In this manner it is possible to retain, between each
abutment 18 and therelated soap bar 2, awrapping sheet 22 which is fed by means of an appropriate device generally designated by thereference numeral 23. - In the illustrated example, it is assumed that the
wrapping sheet 22 is formed by mutually coupling twostrips respective rolls 26 and 27 (figure 3) and are directed, throughrespective series tension rollers unwinding rollers blade 34 which cuts segments of the required length which indeed constitutes thewrapping sheets 22. - A separation and orientation device 35 (hereinafter simply termed separator), arranged downstream of the
blade 34, mutually spaces the sheets at the exit of the rotatingblade 34 and orientates them from a horizontal entry position to a vertical exit position. - The
separator 35 is composed of a flexible element, for example belts 36 (or other equivalent flexible element) which are wound aroundpulleys belts 36 have a four-sided configuration, with a horizontalupper side 41 and alateral side 42 which is arranged vertically and continues downward, forming a side 43 which is oblique with respect to the vertical. - Sprung
rollers 44 are arranged in contact with thesides belts 36, grip the sheets and guide them toward anintermittent actuation unit 45. - The
intermittent actuation unit 45 is constituted by a pair of contra-rotatingrollers side 42 of theseparator 35. - A
further unit 48 is arranged after theintermittent actuation unit 45, defined as the sorting unit, since the sheets which arrive from theintermittent actuation unit 45 mutually partially overlap inside it. Saidunit 48 is composed of a further series of sprungrollers 49 which are arranged on a vertical plane and in front of which aflexible element 50 is tangentially in contact; said flexible element is for example composed of belts or other devices closed in a loop around a set of threepulleys - Said
pulleys flexible element 50 has avertical section 54 in tangential contact with therollers 49 and anupper section 55 which is inclined with respect to the vertical and forms a sort of a funnel together with the upper rollers of theseries 49. - The
belts 36, theflexible element 50 and therollers intermittent actuation device 56 so as to intermittently activate therollers belts 36 when they receive thesheets 22 from said belts and so as to then reduce said speed as soon as the sheets have left theelement 36 and subsequently bring it to the same speed aselement 50 when the sheets are picked up by thesorting unit 48. - The described apparatus is completed by a
device 57, hereinafter termed insertion unit, which places thesheets 22 between thesoap bars 2 and theabutments 18. - Said
insertion unit 57 is constituted by a flexible element, for example by a pair of belts 58 closed in a loop aboutpulleys flexible element 50 to the point of tangency B of theconveyor 1 with respect to thetransfer unit 10. Conveniently, thepulleys 60 for guiding the belts 58 have a minimal diameter in order to allow to move the output of theinsertion unit 57 as close as possible to the point of tangency B. - In order to retain the sheets on the upper section of the belts 58 there is a plurality of
rollers 61 in tangential contact therewith. The speed of theflexible element 50, of the belts 58, of theconveyor 1 and of thetransfer unit 10 are perfectly identical, so that thesheets 22 arrange themselves over the soap bars with zero relative speed. - The operation of the described device is as follows. The
sheets 22, which are cut from thestrips blade 34, are mutually spaced and directed by theseparator 35 between therollers intermittent actuation unit 45 and are guided between therollers 49 and theflexible element 50. As soon as thesheets 22 leave theseparator 35, the speed of therollers sorting unit 48. - Since the plane of tangency between the
rollers 49 and thevertical portion 54 of theflexible element 50 is slightly offset with respect to the plane of tangency of therollers sheets 22 which descend initially make contact with theinclined section 55 and are then guided laterally by said inclined section before being gripped between therollers 49 and theportion 54. - However, since the advancement speed of the
sorting unit 48 is lower than the descent speed of thebelts 36, the terminal flap of the sheet previously gripped between therollers 49 and theflexible element 50 overlaps the initial flap of the sheet which is lowered by therollers insertion unit 57 have mutually overlapping leading and trailing edges and are inserted between thesoap bars 2 and therespective abutments 18 in this configuration. - The rate at which the sheets are fed by the
insertion unit 57 is such that in the point of tangency B the central region of the sheets, i.e. the one which does not overlap the other regions, is arranged between the soap bar and the abutment. Upon the subsequent lifting of the elastic supports 21, thesheets 22 remain secured at said central region. - During subsequent travel up to the
pulleys 9, thejaws clamp elements 15 are actuated so that they close; said clamp elements cause the downward folding of the front and rear flaps of the sheets and the gripping of the soap bars, which can thus be transferred downstream toward thefolders - A substantial prerogative of the invention is constituted by the fact that the overlap of the sheets along the section which corresponds to the
portions grip elements 15 significantly closer together, with considerable advantages in productivity. The structure of theconveyor 10 is furthermore considerably simplified, and said conveyor no longer requires clamps for picking up the sheets and placing them on the soap bars. - In the practical embodiment of the invention, the shapes and dimensions may vary according to the requirements.
- For example, instead of the sprung rollers it is possible to provide belts closed in a loop.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the scope of each element identified by way of example by such reference signs.
