SHLU 2 UP 6 O O O o o o o @9/ d Q7 ms s MACHINE FOR ASSEMBLING A PIVOTABLE HANDLE WITH A PACKAGE The present invention relates to a machine for forming and placing a handle in position on a package.
The technical field of the invention is the mechanical workingof metals and more particularly of wire.
Apparatus are already known for mechanically forming and placing handles in position on packages.
One of the known apparatus for forming the loops of the said handles includes inter alia a part consisting of two complementary elements, in one of which is formed a cavity of the shape of the loops to be obtained.
The portion of wire forming the handle, the ends of which are to be shaped, is forcibly engaged in the said elements so that their shape is imparted to the said ends. As the pressure is continued, the loop is formed inside the handle support studs. Once the handle has been completely formed, the elements are separated so that the handle, then firmly attached to the package, can be removed. This operation is carried out with momentary deformation of the wire.
This process and the apparatus for carrying it out have a certain number of disadvantages such as: the need to use considerable power to force the wire to match the shape of the loops; the need to form handles from ductile wire having particular mechanical characteristics in order to reduce the forces necessary to form them as much as possible; limitationof the choice of the section of the wire used; low efficiency of the machine.
Because of the ductility of the material used and the section of the wire, the handles thus obtained do not always have the required lasting qualities necessary to fulfil their function.
The aim of the present invention is to remedy these disadvantages.
The objective to be attained is a machine which enables handles to be formed and positioned on packages, from wire and in the course of a continuous sequence of operations, whatever may be the nature and the section ofthe said wire used, in such a way that these handles can no longer be subsequently separated from their packages.
The objective is attained by means of the machine in accordance with the invention for forming and placing a handle in position on a package having cavitied support-bosses, which machine is fitted with an apparatus for shearing the wire and bending the portions of wire thus obtained approximately at right angles at both ends, and with a working head comprising a fixed element and a mobile element for forming the handle, which machine has on the one hand means for keeping the endsof the previously bent handle in the axes of the orifices of the said support-bosses and on the other hand two punches arranged on either side of the package and on the same diametrica] axis which moving oppositely, contact the said ends of the handle so as to introduce them through the said orifices in the said support-bosses and bend them a second time, bearing against two stops arranged in the lower portion of the said fixed element of the working head, in order to form two loops, the package being free to move along its longitudinal axis so that it can move during the formation of the loops.
In accordance with an example of an embodiment, the means for keeping the previously bent ends of the handle in the axes of the orifices of the said supportbosses, are two assemblies of two positioning arms which act on each of the said bosses like pincers to bring them into the plane of motion of the mobile portion of the said working head. Eachassembly of two arms is linked to one of the said punches so that pivoting of the said arms is obtained upon movement of the punches by means of a finger rigidly attached to each of the arms, which finger co-operates with an opening formed in a plate driven by the punch.
The said stops forming the lower portion of the fixed element of the working head extend on either side of the package in a position parallel with its longitudinal axis and their lower ends are situated adjacent to the said support-bosses and above them.
The said punches also move adjacent to the stops and below them, in a plane perpendicular to the longitudinal axis of the package and in which plane the said orifices of the support-bosses are situated.
The principal advantage of the machine resides in the fact that, once the handle has been formed, it enables the loops to be formed at the ends of the handle and the latter to be attached to the package in a single opera tion.
A further advantage of the invention is the possibility of obtaining handles which last excellently from wire having the required properties of elasticity and rigidity: for example of galvanized steel or the like.
A further advantage of the invention is that handles can be made whatever the section of the wire.
Lastly, because of the very principle of the invention, the handles thus formed and mounted pivotably on the packages are rendered inseparable from the said packages.
A better understanding of the invention will be obtained on reading the following description, given solely by way of a non-limiting example and with reference to the attached drawings in which:
FIG. 1 is a diagrammatic elevation of an embodiment I of machine in accordance with the invention;
FIG. 2 is an elevation of the upper portion of the machine showing the apparatus for cutting and bending the wire, the fixed and mobile elements of the working head for forming the handles not being shown;
FIG. 3 is a longitudinal section of a punch/positioning arm assembly for suitably arranging the packages on the machine;
FIG. 4 is a section along the line IV-IV of FIG. 3; FIG. 5 is a plan of a punch/positioning arm assembly, and
FIG. 6 is a partial elevation of the working head illustrating the formation of a handle and placing of it in position on a package.
One embodiment of machine in accordance with the invention illustrated in FIG. 1 comprises a mechanical conveyance apparatus 1 for the packages 2 to bring the latter opposite working head 3; a vertically mobile apparatus 4 to bring the packages into the correct position depending upon their height, so that the orifices 2a of their support-bosses 2b are opposite the ends of the handle which are subsequently to be engaged therein,
and apparatus 5 for unwinding the wire 6 of a coil 7 mounted for free rotation on a support 8; an apparatus 9 for shearing the wire 6 and for bending the ends 60 of the portions of wire 6b obtained by shearing; a combined apparatus 10 for bringing the bosses 2b of the packages 2 into the correct position in the horizontal plane and for effecting a second bending to form the loops at the ends of the handles 11; an apparatus 12 for transferring grips 13 stored in a reserve 14; an apparatus 15 for arranging the said grips 13 in the unwinding plane of the wire 6; a control consul 16.
The machine has means for its operation to be controlled manually or automatically. Reference is made to FIGS. 1 and 2.
The wire 6 wound around a reel 7 mounted for free rotation on a frame 8 is directed towards the organs of the machine by apparatus with friction wheels 5a.
The operation of forming and attachment of the handle to the package starts after the grip '13 has been placed in its waiting position..The said grip 13 is transferred from the reserve 14 by means of a pneumatic apparatus 12 which brings it into a two-position receptor organ 1S worked by a pneumatic ram 15a.
The said receptor organ 15 has a cell 15b of generally rectangular form and able to contain a grip 13, and is mounted to pivot in the vertical plane so that the said grip is engaged therein when the said cell 15b is vertical. In its position awaiting the wire, receptor 15 is in the horizontal position. The said ram 15a is pivoted on a support 17 fixed to the structure 30 of the working head 3.
The wire 6 driven by the apparatus 5 is firstly engaged in the grip l3 and is sheared toform a section 6b which is bent through 110 a first time at its ends by two tools 9a, when it enters into contact with a stop 9b which instantaneously generates a signal controlling rams 9c on the rods of which are mounted the said tools 9a. These rams are in a same vertical plane, are inclined by symmetrically relative to the vertical axis of the machine and are fixed on two supports 9d rigidly attached to the apparatus 9.
So that handles of different lengths may be formed, depending on the dimensions of the packages, the rams 9c are carried through their supports 9d by carriages 9e, which move in a horizontal plane under the influence of a gripping organ 9f driving an endless screw which co-operates with a thread formed in the carriages 9e..Each of the said carriages has a fixed forming element 9g on which each end 6a of the portion of wire 6b is bent when the tools 9a impinge against the said ends.
After the latter ends have been bent, the portion of wire 6b is transferred horizontally so as to arrange it with its grip 13 opposite working head 3.
The said working head 3 (FIGS. 1, 2 and 6) consists ofa fixed portion 3a and a mobile portion 3b which cooperate together to form the handle.
The portion 3a is rigidly attached to the structure of the apparatus and the portion 3b is attached to a carriage 3c which is moved vertically. The latter is driven by a ram 3d and is guided by two slide-blocks 3e which each co-operate with a slide 3f.
Below the working head 3 is arranged the combined apparatus 10 for bringing the support-bosses of the package horizontally into the correct position for the handles to be placed in position.
The said combined apparatus 10 consists of two assemblies 10a carried by two carriages 10b moved towards each other in a horizontal plane parallel to the one in which the said carriages 9e move so as to place the assemblies l0a in the correct position depending on the dimensions of the packages. The spacingof the carriages 10a is adjusted by two gripping organs 100 which each drive an endless screw which co-operates with a thread formed in the said carriages 10b.
Each of the assemblies 10a (FIGS. 3, '4 and 5) consists of two curved positioning arms 10d hinged to pivot in the horizontal plane about two axes l0e. The said axes 10e are attached to an element 10f of the said assembly 10a, which element is rigidly attached to the said carriage 10b. Each of the arms 10d bears at its end a claw 10g having a recess 10h for better cooperation with the support-bosses 2b of the packages to bring them opposite working head 3 and into the axis of symmetry of the arms 10d.
The arms 10d are pivoted by means of a ram 10: which drives a punch l0j to which are linked two plates 10k. The said arms 10d also bear a finger 101 which cooperates with a Z-shaped port 10m formed in the said plates 10k. The shape of this porton the one hand enables the arms 10d to be pivoted and on the other hand enables them to be maintained in their closed position while the punch 10jcontinues its stroke towards the package to form the loop.
The fixed portion 3a of the working head 3 (FIG. 6) has in its lower portion and extending downwardly, two stops parallel to the longitudinal axis of the package and arranged on either side of the latter.
The said stops 3g are rounded at their lower ends at 311 and have on their exterior faces' 3i a flat portion 3j diverging downwardly by an angle of 10 relative to the vertical. The said punches l0j move adjacent to the said stops 3g, driving the said positioning arms 10d as they go.
Afterthe said portion of wire 6b has been transferred opposite the said working head 3 under the influence of the ram 3d, the mobile portion 3b driven by the carriage 3c impinges against the fixed portion 3a, thus imparting the forms of the said elements 3a/3b to the portion of wire 6b and bringing the ends 6b before the orifices 2a of the support-bosses 2b. Under the influence of the then biased ram 101', the said punches l0j move towards the package and by means of the arms 10d acting on the said bosses 2b bring the latter substantially into the axes of the previously formed said ends 6a.
Correlatively, the said punches l0j enter into contact with the latter and engage them, bending them a second time at 6c in the orifices 2a of the said supportbosses 2b by bearing on the portions 3h of the said stops 3g.
The end portions 6b, then forming closed loops held captive by the said support-bosses, hold the handle on the package.
During the formation of the loops and at the second bending of the ends of the handle, the package driven by the portion of the handle pushed by the punch, moves towards the top of the machine by an amount A. During this motion, it is kept centered by the positioning arms 10d.
As already mentioned, the machine may operate manually or automatically and may or may not be servo-assisted.
The different organs are manoeuvered by means of rams which may be pneumatic or hydraulic; it is quite obvious that this could be done by any other means.
Of course, without departing from the scope of the invention, various modifications could be made by a man skilled in the art to the apparatus described above solely by way of non-limiting examples.
