Description

PROCESS FOR OBTAINING ARTICLES OF MULTIPLE FORMATS FROM
OF COMPONENTS TO BE ASSEMBLED AND FROM THE SECTION
CROSS-SECTION OF EIENENTS OF FINISHED AND UNEQUAL LENGTHS
AND DEVICE FOR IMPLEMENTING IT.

The subject of the present invention is a method of obtaining
retention of articles of several formats from components
to be assembled and coming from the cross section
of elements of finite and unequal lengths and a device
for its implementation.

This method and this device make it possible to choose
the different components necessary to obtain an ar
ticle, in response to a set of commands that define
each one a type of articles.

In particular, this method establishes as a function of a
set of commands, an inventory of components to be cut
based on at least two articles of different formats, one
so-called "priority" format and so-called "secondary" format, or
at least three different lengths of components.

This invention applies more particularly to
the production of articles such as picture frames and
various dimensions: squares, rectangles, polygons, circles,
ellipses and other curves, closed or not, which are consti
killed by the assembly of components of suitable dimensions,
from the cutting of shape and nature sticks
laughed. The finished article may also include a plate of
front cover and a rear support between which must
be placed an engraving, a photograph, a painting, etc.

Currently, to make a frame, whatever
either its nature, its form, its format and its quality, it was born
cease to carry out a series of coordinated operations of
cutting, assembling, and making of the different elements
constitutive of the framework.

 The first of these operations consists in cutting a strip of wood, of hard synthetic material, of metal, of metal alloy, etc., of various shapes and sections, into components of dimensions appropriate to the production of the frame.

 This cutting operation is carried out by means of various conventional devices such as saw blade, cutter, etc., arranged to allow rapid cutting.

 The main problem of these conventional devices for cutting baguettes lies in the management of the cut of the scraps resulting from the cutting of the baguette into components of determined length.

 Indeed, the length of the rod hardly ever corresponds to a multiple of the length of the component (s), which has the consequence that there remains an unusable length of rod or "fall".

 This fall is all the more frequent as most of the cutting devices currently used are designed only to cut the baguette to a predetermined length, without taking into account either its initial length or that remaining to be cut from a certain length of rod.

 However, when the length of the strip to be cut becomes less than the actual length of the component, it is no longer possible to make a cut, and the result is that this remaining length becomes unusable and must then be discarded.

 Such a remaining length which is variable depending on the length of the component and the original length of the rod can represent a fall of 10 to 50 centimeters. We understand that this represents a bulky and significant amount of falls to manage and considerably increases the coat of this operation.

 In addition, these devices are frequently arranged and adjusted to cut rods whose initial length is greater than a minimum reference, which has the consequence of preventing any use of rod of shorter length.

 When the operation is carried out manually, the operator easily understands which length of baguette he has to cut in order to optimize the cut and reduce the drop of unusable baguette. However, this manual optimization is often random because it depends on the subjective assessment of the operator. Therefore, even if it is possible to reduce the length of the drop, there is still a very large total length of unusable rod.

 To overcome these drawbacks, other devices are known which allow, after long and tedious adjustments, a resumption of these falls with a view to limiting the resulting loss.

 However, these devices are complex and they require for their implementation and adjustment the presence of qualified personnel whose remuneration is high.

 These adjustments, depending on their complexity and their number, require a more or less long time during which the production devices are unusable, so that the expediency of these adjustments depends essentially on the number of rods to be cut.

 The second operation is a so-called assembly operation. This operation consists in assembling the different components together to produce an article known as "intermedia".

 I1 are devices to perform this operation, but they are complex and their implementation requires the intervention of several people.

 This manual assembly in series is often of poor quality, due to the production rate which is imposed, the personnel being unable to carry out a perfect assembly of the components and the intermediate article, which often exhibits irregularities.

 To solve the difficult problem of the existence of irregularities in the assembly of the various components, in addition to the quality controls which are regularly carried out, semi-automatic devices are known whose action is less random.

 However, due to the complexity of this operation, these devices are generally very difficult to implement and of a complicated design because they require the use of very sophisticated mechanical and electronic techniques.

 The third operation consists in depositing on the one hand a "front" protective plate made of transparent material such as glass and, on the other hand, a "rear" support made of relatively rigid material such as cardboard, wood, synthetic material. hard, glass, etc.

 This installation of glass and cardboard is a long operation which, until now, is entirely manual, very expensive and which overcharges the cost price of the final article.

 This part of the work can only be automated and mechanized with machines whose complexity and cost of production are generally disproportionate to the gain in productivity that they would provide. Therefore, there is no machine to perform this installation of glass and cardboard.

 The object of the present invention is to provide a method for making articles, in particular frames, and a device for its implementation which overcomes the various drawbacks which present methods and devices present, by allowing the manufacture of fully automated articles, which manages the cutting of basic elements by limiting falls to a suitable minimum.

 To this end, the invention relates to a process for obtaining articles of several formats from components to be assembled and coming from the cross section of elements of finite and unequal length.

 Referring to Figure 1, we see that to illustrate the invention using rods 1 made of various materials (wood, hard synthetic material, metal, metal alloy, etc.) of unequal and finite lengths.

 The rod 1 has at each of its ends irregularities 2 coming from various causes (machining, fragmentation during the various manipulations from its manufacture to its use, etc.) and it is necessary, before starting its sectioning into components, " to initialize "at least one of its ends, in order to have a precise origin. For this, we cut the beveled end whose inclination is variable depending on the shape of the frame that we want to obtain. If we want to make a tabbed assembly, but of course this cutting can be different and , in particular, it can be a simple cross section.

 This initialization operation of the rod 1 will be described later, but it is important to note that it is carried out according to the invention to limit the resulting cutting as much as possible.

 From this initialized rod 1, it is sectioned by managing this sectioning and minimizing the fall in order to obtain components 4 of different lengths. These components 4 will either be directly packaged in containers 3 (bag, sachet, package, box, etc.) to be sold in the form of a kit, or assembled to obtain so-called intermediate articles 8. This kit may advantageously include the other constituents necessary for the production of the frame or final article (protective plate 5, support plate 6, assembly and fixing member 7, etc.) as shown in FIG. 2.

 Likewise, the intermediate article 8 is advantageously completed by a front protective plate 5, generally made of glass or of a hard, transparent or translucent synthetic material and by a rear support plate 6.

 This rear support plate 6 of a known type is made of various materials (cardboard, synthetic material, metal, etc.) and may optionally include an easel or other means which ensures the installation and maintenance of the frame in a vertical plane.

 To facilitate the installation and removal, by the user according to his tastes and desires, of photography, painting, engraving, etc., inside the space delimited between the external protective plate 5 and the rear support 6 removable fastening means 7 for this rear plate are provided.

 Similarly, to avoid any deterioration or damage resulting from shocks produced during the various manipulations of this frame 10 from its production to its installation by the user at the location of his choice, protective corners 9 are placed at each of the edges as shown in Figure 3.

 To illustrate the invention, a rectangular frame of a conventional type has been chosen which is known as a final article 10. This frame 10 results from the assembly at a right angle of two pairs of components 4. The assembly of the four sides assembled constitutes a so-called intermediate article 8.

 Of course, this frame format 10 is not limiting and square, polygonal, oval, circular, etc. frames can be produced from rods 1 of different natures and of varied sections.

Referring to FIG. 4, it can be seen that the device for obtaining articles of several formats from components to be assembled and coming from the cross section of elements of finite and unequal length comprises - a storage unit 100 which has a sto store
ckage and means of setting up in this store
elements of finite and unequal lengths to be cut.

- a sectioning unit 200 which includes a mistletoe rail
dage, means for holding and guiding the elements to
cut, cutting means according to determined lengths
of these items as well as an intermediate store of sto
ckage of cut elements called components and means
placing these components in this store, - an assembly unit 300 which includes a laying table,
means for positioning and maintaining the components
on the laying table, an assembly table, means of
placing and maintaining these components on the table
for assembling and means for assembling said components
between them to produce an intermediate article, - a confection unit 400 which comprises means of placing
in place of different constituents of the final article and
means for installing fixing members of these
constituents, - a packaging unit 500 which includes means for the
filing of protective corners and for the installation of a
covering film for final articles, - a packaging unit 600 which includes means for
placement of wrapped final articles, in fairy tales
nants, - a control unit 700 which comprises means of trai
information which contains memories which pos
data management information.

 It is understood that this device is modular and that it can include only some of these units depending on the degree of optimization of the desired automation.

 This device must, however, contain at least one storage unit and one sectioning unit in order to be able to optimize the cutting of the sticks by limiting falls.

 Likewise, it is possible to envisage the association of several similar storage and sectioning units independent or not on the same frame to increase the efficiency of the device.

 In the installation which is implemented, the storage store 11, said supply store, makes it possible in practice to store a number of rods 1 to be cut, variable as a function of the autonomy of the machine and of its production rate. For example, for a rate of 100 components 4 sectioned per hour, this magazine 11 has thirty support rails 12 staggered intended to individually receive a strip 1 to be sectioned of finished and unequal length.

 This organization of the food store 11 is here designed to allow manual insertion by an operator of the rods 1 into a corresponding support rail 12.

In another embodiment, it may be different to constitute an assembly capable of being automatically recharged by appropriate mechanical means such as an arm associated with gripping means or any other mechanical device allowing the introduction and the establishment rods 1 to be cut in the support rails 12 of the supply magazine 11.

 By way of example in the latter case, the rods 1 of finite and unequal length to be cut can be presented in another storage warehouse adapted to allow installation according to a suitable rapid and easy distribution by the arm of the said rods 1 to the corresponding location in the food store 11.

 This food store 11 comprises a frame 13 on which a chain conveyor 14 is arranged. To remedy the various problems frequently encountered when using a conventional food store, the store 11 has advantageously been arranged in accordance with the invention along a course inclined in a direction as illustrated in FIG. 5.

In addition, this inclined path of the food store 11 facilitates the positioning of the rods 1 to be cut by the operator. 7
The drive of this magazine 11 to allow the movement of the rods 1 to be sectioned from this storage unit 100 until their introduction into the sectioning unit 200 is carried out step by step. This step-by-step mode is obtained here by driving the chain conveyor 14 by two jacks 15, 16 associated with connecting rods 17 connected to a pinion 18 associated by a suitable kinematics to a pinion 19 integral with the upstream end of the chain conveyor 14.

 This step-by-step drive can also be carried out in variants, by other equivalent means such as by synchronized electric motors associated by appropriate kinematics at the upstream end of the conveyor. Likewise, it is also possible to use belt conveyors comprising staggered support rails, or a conveyor driven by suitable kinematics by any mechanical means adapted to the scope of the person skilled in the art.

 This conveyor 14 is driven in one direction in accordance with that indicated by the arrow F1 and at a constant speed preset and adjustable as a function of different parameters such as the sectioning rate of the rods 1 and / or the rate of obtaining articles.

 Furthermore, in order to solve the problems of maintaining the rods to be cut 1, the food stores currently in use have flanges or supporting support pieces which require long and tedious adjustment as a function of the dimensions of the rods.

 According to the invention in order to avoid the use of these complex parts, the supply magazine 11 comprises inclined support rails 12.

 The staggered support rails 12 are non-continuous over the entire width of the magazine 11 and are constituted by a series of sections of rails of appropriate length to ensure the maintenance of the strips 1 to be cut. They are mounted fixed and regularly spaced as illustrated in FIG. 7 and have a suitable conformation (in T or in U) to avoid any untimely fall of the rods 1 to be cut during the travel of the conveyor 14 and in particular during the stage corresponding to the introduction of the sectioning strip 1 into the sectioning unit 200.

 In an alternative embodiment, these staggered support rails 12 could be continuous and consist of rails of length identical to the width of the supply magazine 1.

 Indeed, the rods to be cut 1 of finite and unequal length introduced at the downstream end of the conveyor 14, are maintained, in an inclined position, by the rails 12, all along the route, from the upstream end of the conveyor 14 to the downstream end. At the end of the race when the support rail 12 is in the horizontal position, the strip to be cut 1 is in a horizontal plane in the sectioning unit 200. In this position corresponding to the introduction of the strip to be cut 1 into the unit section 200, as illustrated in Figure 7, the support rail 13 on which the rod 1 rests plays the role of guide while ensuring the maintenance and retention of the rod to be cut 1 whatever its nature, shape and dimensions.

 Furthermore, to increase the lateral retention of the rods 1 to be cut in this position which precedes their introduction into the sectioning unit 200, vertical plates (not shown) made of flexible and flexible material such as rubber are arranged on the spar. of the frame 14 which surmounts the food store 11.

Thanks to the properties of flexibility and elasticity of the rubber, these regularly spaced plates above the support rail 12 of the supply magazine 11 allow a passage without friction of the rail 12 during its course
It is important to note that according to the invention, this supply store 11 makes it possible to store sectioning sticks 1 is variable and can advantageously be between several tens of centimeters and several tens of meters.

 It is understood that the limitation of the maximum male length of the rod essentially depends on the dimensions of the room inside which the device is operated. Likewise, for reasons of convenience and practicality, manufacturers limit the proper dimensions of the rods whatever their nature (wood, synthetic material, etc.) so that it will generally remain lower than a given rating.

 This possibility of using rods 1 of finite and unequal length has a primary economic advantage because it is possible in this way to cut rods 1 which for various reasons (defects, initial length too small, etc.) were unusable in the devices currently used. , and therefore intended to be discarded.

 The frame 14 of the food store has 11 at one of its ends a stop plate which is arranged at an inclination identical to that of the store 11.

 The position of the rod 1, in the phase of introduction into the sectioning unit 200, on the supply magazine 11 is determined with precision. To do this, two sensors 20, 21 of the photoelectric cell type, inductive, capacitive or other proximity detectors are arranged a spar 22 of the frame 14. These two encoders 20 and 21 are advantageously spaced apart by a spacing D.

 Referring to FIG. 5, it can be seen that the distance D between the first sensor 20 and the second 21 is adjustable by simple displacement of the position of the first sensor 20. The second fixed sensor 21 is positioned in close proximity opposite on the one hand from the entry into the sectioning unit 200 and on the other hand from the stop plate.

 To allow better optimization of the cutting of the strip to be cut 1 and in particular to limit falls when using very short strips 1, a third sensor (not shown) could be added.

 This sensor, placed between the first sensor 20 and the second sensor 21 would determine the position of the strip to be cut 1 either in relay to the first sensor 20 as soon as the strip to be cut 1 would have a length which can no longer be detected by the sensor 20, either independently of the first sensor 20, that is to say for lengths of initial rods to be cut 1 which cannot be detected by the sensor 20.

 This third sensor whose position is adjustable can be either arranged on the frame by any suitable means, or arranged on an independent support and mounted vertically movable between two positions by any suitable means. A first erased position in which it is raised and inert and a second active position in which it has descended and where it determines the position of the rod 1.

 Thanks to these sensors the position of the strip to be cut 1 is determined. This determination of the position of the strip to be cut, that is to say either of its useful length remaining to be cut, or of the initial own length of the strip is taken into account by information processing means for optimize the section into components 4 of determined length as a function of parameters previously determined as will be described later.

 In an embodiment in which the nature of the strip to be cut 1, that is to say its shape and the material in which it is made, is also managed, the sensors are associated with shape detectors or any equivalent means .

 The information collected is transmitted by conventional connections to the information processing means of the control unit 700 which manages it to optimize the cutting of the rod and the production of frames of different kinds.

 To facilitate the introduction of rods of finite and unequal length to be cut 1 in the sectioning unit 200 during the initialization operation of one of the ends of the strip 1, two wheels 26 and 27 are arranged opposite from each other at the entrance to this sectioning unit 200.

 The face of these two wheels 26 and 27 constitutes a useful face which is smooth to facilitate the training of the strips to be cut 1. In addition, to improve the drive of the sectioning sticks 1, the useful face is coated with any material which offers qualities of wear resistance and elasticity and which has a smooth and uniform texture.

As more particularly illustrated in FIG. 5, the upper wheel 26 is a smooth wheel secured to a rotation shaft so that it is mounted free in rotation as indicated by the arrow F2 to facilitate movement of the strip to be cut 1 from the feed store II to the sectioning unit 200. This wheel is mechanically secured by an arm 28 to jacks 29 so that it is mounted vertically movable between two positions as indicated by the arrow F3. A first position erased in which it is inactive and placed above the downstream end of the sectioning unit 200 as shown in FIG. 5 and a second active position, during the phase of introduction of the rod 1 for its initialization, in which it is lowered in contact with the rod 1 as illustrated in FIG. 6
The lower wheel 27 is a smooth wheel which is mounted integral with a rotation shaft. This wheel is secured by suitable kinematics to a rotary actuator 30 so that it is movable in rotation as indicated by the arrow F3 to facilitate the driving of the strip to be cut in the sectioning unit 200 on a guide rail. horizontal 31 on which it moves.

 The sectioning unit 200 has a clamp 40 which has a body 41 which has a central housing adapted to the shapes of the rods.

 This clamp 40 mechanically subjected to appropriate means such as jacks 42 is movable in horizontal translation, over a determined stroke, such as that represented by the arrow F5 parallel to the plane of movement of the strip to be cut 1.

 The strip to be cut 1 which is in a position conforming to that which is shown in FIG. 8 is moved in the sectioning unit 200 along the horizontal rail 31. After entering this sectioning unit 200, and as soon as the wheel 26 has resumed its erased position, the strip to be cut 1 is held by the clamp 40 adapted to ensure the support and support of the strip regardless of its conformation.

 To improve the retention of the strips to be cut 1, elastic means (not shown) of the spring leaf type are advantageously arranged along the horizontal rail 31 of the sectioning unit 200.

 These leaf springs have a conformation which offers a large contact surface in order to maintain the strips to be cut. In addition, these leaf springs make it possible to make up for any defects that the rods to be sectioned may have 1. In particular, they make it possible to remedy the bending defects of the rods which result from their manufacture or from the various manipulations to which they are subjected.

 Referring to the figure, we see an encoder 43 consisting of three cells 44, 45, 46 of a conventional type such as photoelectric cells, inductive, capacitive or other cells, which is arranged on a support plate of the frame 14 above the sectioning unit 200 opposite its entry and parallel to the horizontal plane of movement of the strip to be sectioned.

 A plate 47, in accordance with that shown in FIG. 11, secured to the jack 42 is movable according to a movement coordinated and synchronized with that of the clamp 40. This plate 47 in association with the clamp 40 moves according to a determined stroke and it covers in this way at least one of the three cells 44, 45, and 46 according to one of the eight alternatives shown in FIG. 12.

 Referring more particularly to this FIG. 12, the three cators 44, 45 and 46 have been shown diagrammatically by circles. When these sensors 44, 45 and 46 are masked by the plate 47 they are represented by solid circles while when these sensors 44, 45 and 46 are not hidden by the plate 47, they are symbolized by empty circles.

 As a result, thanks to this information transmitted by the sensors 44, 45 and 46 by conventional connections to the processing means, the recoil of the rod 1 to be cut is refined over a stroke determined by the clamp 40.

 We imagine that it is also quite possible to make an encoder from the integral contacts of a mechanical cam device or any other equivalent means.

 This sectioning unit 200 comprises means for cutting rods of the guillotine type 50. It would of course be possible to use other means (saw blade, etc.) which make it possible to cut transversely to predetermined lengths and according to an appropriate section depending on subsequent assembly, the rods 1 to obtain the desired components 4.

 To avoid any unwanted sliding, pivoting or displacement of the strip to be cut 1, stops 51 whose position is adjustable by jacks, hold the strip vertically under the cutter 50.

 Similarly, stops 51 ′ whose position is adjustable by jacks horizontally hold this section rod under the cutter 50.

 Keeping the strip to be cut 1 in a vertical and horizontal plane is necessary to avoid any unwanted movement (rotation, pivoting, tilting, horizontal or vertical translation) of the strip which would affect the precision of its cut by the cutter 50.

 This sectioning unit 200 also includes a holding clamp 52 disposed downstream of the cutter.

 This clamp 52 shown in Figures 9 and 10 is mounted on a support 53 mechanically secured to a cylinder 54 whose stroke is advantageously limited and fixed. This support 53 is movable in vertical translation in a direction parallel to the advancement plane of the rod in the guide rail as illustrated by the arrow F8 in FIG. 8.

This clamp 52 is subject to a rotary actuator 55 so that it is movable in rotation between a retracted position in which it is located above the strip to be cut 1 as illustrated in FIG. 9 and an active position in which it found in contact with the end of the rod 1 as shown in Figure 10
The support 53 is surmounted by a clamping rod 56, the free end of which is provided with a cylindrical end piece 57 which is free to rotate, the external surface of which is covered by an elastomeric material. This clamping rod 56 is mechanically associated with a rotary actuator 58 so that it is movable in rotation between a retracted position (FIG. 9) and an active position (FIG. 10) in which it ensures the vertical retention of the rod at section 1.

 The use of cylinders which here are pneumatic although offering greater flexibility of use and allowing greater speed of operations is in no way limiting. In alternative embodiments, recourse could be had to hydraulic, electric jacks or any other equivalent means.

 However, the implementation of hydraulic cylinders is more complex because it requires the use of auxiliary hydraulic circuits. In addition, these hydraulic cylinders have a longer response time and are therefore slower, which affects the rate of operation of the entire device. Similarly, the use of electric actuators requires complex ancillary devices to allow coordinated control of the various actuators of the device.

 To manage and optimize the cutting of the rod as a function of its length, an encoder 60 is integral with the frame opposite the upstream end of the sectioning unit 200.

 This encoder 60 is constituted by an electric motor 61, one of its outputs of which is integral with a pinion 62 which is engaged on a horizontal rack 63 parallel to the guide rail 31 and for holding the strip to be cut 1.

 This rack 63 is integral with two pneumatic cylinders 64 and 65 of coupled drive associated with the cylinder 54 integral with the clamp 53 holding the strip to be cut, so that the stroke of the cylinders 64 and 65 is adjusted as a function of the length of the component 4 that one wishes to obtain.

 To maintain the drive jacks 64 and 65 in a suitable position adjusted as a function of the length of the component 4 which it is desired to obtain, an electromagnet 66 is provided.

 In an alternative embodiment (not shown) when using hydraulic cylinders, the coding is carried out by an encoder secured to the frame associated with a rack subject to the hydraulic cylinders.

 However, this embodiment has a more complex mechanical design and a slower speed of execution. In addition, with this embodiment, there is a greater imprecision in the cutting of the rods resulting from variation of the position by displacement (in translation, in pivoting or in tilting) of said rods during their cutting.

 It is understood that this imprecision in the cutting of the rods 1 is detrimental for obtaining components 4 without imperfection and irregularity since they must then be assembled.

 Next to the cutter 50, an evacuation chute 67 is provided to allow the components 4 to fall inside various containers (sachet, bag, cardboard or metal box, case, etc.).

Thus, one can condition the appropriate number of components 4 to produce an article of determined dimension in the form of a kit for individual or professional use, or condition a determined number of components 4 to obtain a series of frames of dimensions and nature. possibly different
To evacuate the falls resulting on the one hand from the original cut of the rod 1 during the initialization operation and on the other hand from the minimum fall resulting from the optimization of the cut of the rod of the means of the type bellows or duct for introducing pressurized air are arranged opposite the cutter 50. Of course, it is imagined that these means are advantageously controlled, as will be described later to operate at the appropriate time.

 Referring to Figure 13, we see that an articulated arm 70 secured to the frame of a design known to the skilled person (which will not be described in detail) is arranged on the frame at the upstream end of sectioning unit 200.

 This arm 70 has at its free end gripping means such as a clamp 71 of a conventional type.

 I1 is movable by an appropriate combination of known means such as jacks or other mechanical or non-equivalent members according to a kinematics which allows two degrees of freedom of movement. A vertical translational movement in accordance with arrow F9 in FIG. 13 along a determined stroke in a direction perpendicular to the advancement plane of the rod and a rotational movement in accordance with arrow F10 according to an angular amplitude less than 90 in a plane parallel to that of advancement of the rod 1.

 Opposite the upstream end of the guide rail 31 of the strip to be cut 1, is arranged, substantially perpendicular to the latter and in a plane parallel to that of advancement of the strips 1, a storage magazine 73 called intermediate magazine which has a series of regularly spaced support rails 74.

This intermediate magazine 73 is here of almost circular shape to be compatible with the stroke of the articulated arm 70 and to allow an appreciable saving of space.
Its capacity is adapted as a function of various criteria and in particular of the yield and of the throughput of the machine, that is to say the number of different components 4 produced per unit of time as well as the number of articles assembled during this same unit time. Of course, its capacity is adjusted to offer an optimal compromise between its dimensions, that is to say the location it occupies within the sectioning unit 200 and the risks of its possible saturation.

 Opposite this intermediate store 73 is arranged a circular crown 75 which comprises a series of stops 76 regularly spaced apart and each arranged opposite a support rail 74 of the intermediate store 73.

 These stops 76, one of which is more particularly shown in FIGS. 14 and 15, are each mounted movable in vertical translation between two extreme positions by a jack 77 fixed to a link 78. A first erased position in which they are housed inside a suitable space provided in the support ring 75. A second active position in which they are raised and arranged in contact with the articulated arm 70.

 These stops 76 each have a sensor 79 which transmits information to the processing means on the position of the arm 70 and therefore on the position of the component which will be deposited on the intermediate magazine 73.

 In another embodiment (not shown), it is possible to envisage using a purely mechanical arrangement which incorporates a ratchet device associated with movable means such as a toothed wheel having stops which would trigger the ratchet when the arm is in contact with one of these stops. However, such a purely mechanical device has the disadvantage of being much slower and less reliable.

 Referring to FIG. 13, it can be seen that an articulated arm 80 of a conventional and known type (which will not be described in detail) arranged on the frame below the articulated arm 70 is mounted movable by displacement means cylinders or other mechanical or non-mechanical type to allow its movement in two degrees of freedom of movement.

 A vertical translational movement in accordance with arrow F11 of FIG. 13 according to a determined and limited stroke between two extreme positions, one erased in the high position and the other active in the low position and a rotational movement in accordance with the arrow F12 d angular amplitude substantially 90.

 This arm 80 comprises at its free end a clamp 81 of a conventional type and suitable for gripping components of different conformations.

 In another embodiment, it is entirely conceivable to use a single arm provided with two separate clamps. However, such an arrangement requires speed and precision of movements and it follows that the use of a single arm requires solving problems of synchronization and coordination of the relative movements of the clamps.

 One of the ends of this intermediate store 73 opens out with regard to an assembly unit 300.

 This assembly unit 300 comprises a horizontal laying table 90 on which the components 4 are placed.

 This table 90 more particularly illustrated in Figures 16 and 17 has a longitudinal slot 91, formed substantially over its entire length.

 A movable stop 92 is arranged integral with the frame in vertical translation in accordance with the arrow F12 of FIG. 16 between an erased position where it is tucked under this slot and an active position where it is raised inside the end downstream of this slot to maintain the component 4 deposited on this table 90.

 A clamp 93 secured to a jack 94 or another equivalent means is movable in vertical translation in the slot 91 over a stroke corresponding to the length of said slot 91.

 Above the upstream end of this horizontal deposition table 90 is mounted on a suitable support a horizontal so-called assembly table 95.

 This table 95 more particularly shown in Figure 20 has a longitudinal slot 96 which extends substantially over its entire length.

 The end of the slot 96 comprises a V-shaped part 97, more particularly illustrated by FIG. 21, the angular opening of which depends on the configuration of the articles to be produced. Here, the components 4 are assembled to produce articles which are square or preferably rectangular frames and therefore an angular sector of 90 has previously been chosen. In other cases, for example frames of shapes other than square or rectangular, that is to say polygonal, we choose an angular sector ap proprié of the part. To do this, we place a part whose angular spacing is that which corresponds to that desired, or in an alternative embodiment, a part 97 is made up of two integral parts which delimit an angle between them, the angular opening of which is modified by a spacing or tightening of the two parts by suitable means.

 It is however important to note that to facilitate the assembly of two components and to ensure their correct positioning at 90C from one another, a longitudinal slot 98 has advantageously been produced in the part 97.

 Of course, this catching-up of the offset originating from the positioning of the ends to be assembled inside the V-shaped piece 97 is identical whatever the angular opening of this piece.

This V-shaped piece 97 is mounted movable in translation by rollers 99 and its position is adjustable by stops 100 arranged symmetrically on either side of the piece in
V 97
Two sensors 101 and 102 arranged on supports are arranged symmetrically on either side of the part in
V. These sensors 101 and 102 deliver information on the assembly of the components to means for processing this information to which they are connected by electrical connections.

 A vertical thrust plate 103 is integral with each of its ends of a jack 104 and 105 whose stroke is determined and limited. In a preferred embodiment, each cylinder 104 and 105 and the plate 103 are mechanically secured by a knurled head 106 disposed on either side of the plate. By screwing or unscrewing the knurled head 106 on the corresponding thread, depending on the length of the components to be assembled, the precision of the stroke of the jacks 104 and 105 is adjusted.

 This plate 103 is movable in vertical translation in accordance with the arrow F15 between two extreme positions.

One erased or moved back in which it is located substantially on the edge of the end of the table and the other active in which it is almost in contact with the V-piece 97. We could use in an alternative embodiment a single jack arranged in the middle part of the thrust plate or even all mechanical devices which allow a translational movement thereof.

 Under this assembly table 95 and under an opening in the laying table 90 is arranged on a support, by known means, a stapler of a conventional type. This stapler (not shown) is movable in vertical translation between a low retracted position and a high active position by a jack. In this high position, it is in contact with the two ends of the two components to be assembled maintained in the V-piece to secure them by depositing a staple.

 Of course, in other embodiments, it is entirely possible to assemble these components by means other than a staple. One could for example use conventional techniques of bonding, welding, etc.

 In particular, these assembly techniques are perfectly suited when using plastic or metal rods.

 To avoid unwanted displacement or deformation of the two components 4a and 4b during assembly and in particular to maintain these two components 4a and 4b while opposing the significant stresses which are exerted during their stapling, pressure stops 110 are advantageously arranged opposite the V-shaped piece 97.

 The frame whose general conformation is in] comprises, arranged parallel to the guide rail of the rods 1, two parallel support rails 111, 112 on which a carriage 120 is mounted movable in translation.

 This carriage 120 of a conventional type supports an articulated arm 121 as shown in FIG. 17 in the three directions of the space, the free end of which has a clamp 122 such as that shown in FIG. 18.

 This clamp 122 has a body 123 secured to two fingers 124 and 125 articulated according to a suitable kinematics by rods 126 associated with jacks 127. The clamp body 122 comprises, secured to its central axis, two support plates 130 and 131 each secured to a cylinder of the clamp 122, the end of which comprises a guide wheel 132 movable in rotation.

 The body 133 of each finger 124 and 125 includes a guide and holding plate 134 slidably mounted between two extreme positions. This plate 134 is advantageously covered with a strip of a flexible and little slippery material.

The body of each finger 124 and 125 also comprises a part 135 constituting a beveled tip.

 To facilitate the maintenance of the components inside the clamp 122 after their gripping, the body 123 of the clamp 122 has a spring leaf 136 which is held in the adapted position under the effect of a magnetic field emitted by two electro - magnets 137.

 This clamp 122 is mechanically secured to the support arm 121. By a combination of connecting rods, links, rollers and other suitable mechanical members, as well as jacks, it is mounted movable in vertical, horizontal translation as well as in rotation. Thanks to this combination of movement and according to an adapted kinematics, the operations of the operator's hand are automatically restored during the assembly of the components 4 to obtain an intermediate article 8.

 The carriage 120 is movable in translation according to a stroke determined in accordance with the arrow F16 of FIG. 17 by jacks integral with a horizontal rack 131 on which a pinion 132 meshes with the output of a motor 133. as a function of the movement of the pinion 132 on this rack 131, the stroke of the jacks 130 is adjusted and therefore a corresponding movement of the carriage and the clamp 122.

 Thus, the stroke of the jacks 130 corresponds exactly to that desired and adjusted so that any positioning error of the components 4 on the assembly table 95 is avoided.

 Under the assembly table 95 in extension of the laying table 90 is disposed a horizontal hatch 140 articulated between a closed position in which it is located in a horizontal plane and an open position in which it is inclined as shown in the figure 28. In this position, it opens onto the upstream end of an inclined belt conveyor 141 associated with the downstream end of another horizontal belt conveyor 142 of the packaging unit 400.

 A sensor (not shown) is arranged on a support at the upstream end of the conveyor 141 to indicate by conventional connections to the information processing means the presence of an article 8 in the packaging unit 400.

 Referring to Figure 28, we see that along this conveyor 142 are arranged three barriers 143, 144 movable in vertical translation according to the arrow F20 of Figure 28 between a cleared position and a lowered active position. Each of these barriers 143, 144 and 145 has a sensor 146 of the electrical contact type which determines the presence of an intermediate article 8.

 The first barrier 143 is preferably provided with a horizontal rack associated with two movable vertical stops to adjust the position of the intermediate article 5 and determine its dimensions. This rack is connected to an encoder which transmits this information by conventional connections to the information processing means as will be described later.

 Perpendicular to this conveyor 142 is arranged a store of glasses 147 of different formats intended to be deposited on the intermediate article 5 as illustrated in FIG. 29. The glasses are advantageously distributed in stacks 147. Each stack 147 corresponds to a format of glass corresponding to the format of the intermediate article 5. A carriage 150 which supports means for gripping glasses such as pneumatic suction cups 151 (FIG. 29) is mounted movable in translation on two parallel rails 152 which surmount the magazine.

 This carriage 150 is movable by a cylinder in vertical translation in accordance with the arrow F21 between two extreme positions, one erased high and the other active lowered.

 The operator collects on the upstream end of the conveyor 142 the intermediate article on which the front glass is placed 5. Possibly he puts the glass 5 exactly back in position and he deposits an engraving, photo, etc., in the intermediate article 8 as well as an external support 6.

 Of course, this operation which is carried out here manually, can be done automatically by means such as an articulated arm associated with means for gripping the constituents to be deposited, stored in a store.

 The operator places the final article 10 on a belt conveyor 153 which has a barrier 154 provided with a rack and two end pieces, which adjusts the position of the final article 10 and measures its dimensions. This barrier also includes an encoder which transmits this information to the appropriate means by conventional connections.

 An articulated arm 160 mounted movable in horizontal translation by a jack 161 in accordance with the arrow F22 in FIG. 30 between an active position and an erased position comprises at its free end three guns 162, 163, and 164 for laying points of a classic type.

 These three guns 162, 163 and 164 are movable in vertical and horizontal translation according to a determined stroke to adjust, as a function of the proper dimensions of the frame, the positioning of the spikes at the appropriate locations.

 The belt conveyor 153 opens onto a plate 165 which is orientable and movable in rotation by known means on which the spikes intended for securing the various components of the frame are removed.

Removable stops whose position is adjustable by jacks or any other suitable mechanical device hold the frame in a position suitable for the placement of spikes
After these spikes are attached, the frame is finished. This frame is placed on a conveyor 166 of the packaging unit 500 where it is deposited either manually or automatically by suitable means of the protective corners 9 at each of the edges of the frame.

 This automatic positioning of the corners 9 can be achieved for example by an articulated arm by suitable kinematics similar to that which would deposit the constituents. The corners would be stored in a batch store according to the dimensions and the nature of the frame so that the arm, depending on the frame, would deposit the suitable corners.

 The downstream end of the conveyor 166 opens out at the upstream end of a conveyor 170 which opens out into a film former 171 and an oven 172 of a known type of the packaging unit 500.

 At the outlet of the oven 172 the downstream end of the conveyor 170 opens onto the upstream end of a transpotter 173 so that these packaged frames are conveyed to a packaging unit 600.

 This packaging unit 600 comprises a receiving plate where an operator collects the frames at the upstream outlet of the conveyor 173 and deposits them in containers (boxes, cartons, etc.) in batches or individually.

 Of course, this operation can be carried out automatically by an articulated mechanical arm or by any other means which allows gripping of the packaged frames and storage in containers.

 To manage all of the means and organs of the device as well as to allow coordinated operation of these organs, the control unit 700 comprises an automaton. In order to allow easy and easy maintenance, this control unit 700 includes indicator lights and a signaling screen on which is displayed, in the event of damage or a problem with the operation of a digit. This figure corresponds to a specific organ or location of the machine so that the operator can easily determine the cause of the damage and its location. In addition, this control unit 700 includes means for autonomously operating the units as well as means for adjusting the production rate.

The flow of the process according to the invention by means of the device which has just been described is as follows
In a so-called control unit 700, a programmed set of information processing such as an automaton, implements an algorithm for managing the sectioning of the rods so that the resulting falls are minimized and the section is optimized. of the baguette.

 This algorithm makes it possible to establish an inventory of the components to be sectioned as a function of at least two different frame formats or at least three different lengths of components.

 This algorithm determines, as a function of obtaining a frame of determined format known as priority and of a framework of another format known as secondary, the length of rod to be cut in order to obtain the component corresponding to the choice.

 The progress of this algorithm is initial each time the following conditions are met - a rod is introduced whose remaining length to be cut or the initial self-length is less than the spacing between the sensors, - natural rods are introduced and of different conformation.

 This algorithm and its procedure for obtaining a component of determined length are explained below.

 This algorithm consists in allocating, as a function of the length of the rod to be cut when it reaches or has a determined length, a section adapted to limit as much as possible the resulting fall as a function of obtaining two different frame formats either at least three different lengths of elements.

 For example, consider the realization of a priority frame whose dimensions are 240x300 and a secondary frame whose dimensions are 130x180 from a rod of initial length of 296 - we make a section of this rod to obtain four components of 300 and four components of 240 so as to produce four so-called priority frames, - the length of the remaining rod being 800, the section of this remaining length is managed in order to minimize the fall as much as possible. For this purpose, the rod is cut to obtain two components of 300 and one component of 180, i.e. a fall of 20.

 Of course, this optimization of the section of the rods whatever its length and its nature corresponds to a set of commands from the various organs of the device and to a coordination of the operation of these organs, as will be described below.

 In addition, from the information transmitted by the sensors, the processing means manage this optimization of the section of the rods and the obtaining of a frame to ensure synchronization of the functioning of the organs of the different units and to avoid any anomalies liable to immobilize the whole device.

 The operator has on a support rail 12 of the supply magazine 11 of the storage unit 100 a strip to be cut 1 without worrying about its length or its nature.

 I1 presses it against this support rail 12 and pushes it against this rail 12 in the direction represented by the arrow F7 until the free end introduced first is opposite the end of the magazine 11 in the stop position against the stop plate.

 As has been described, the limitation of the maximum length of the rod 1 capable of being cut results only from the dimensions of the room and from the practical considerations of the manufacturers of rods.

 The strip 1 to be cut, generally introduced at the upstream end of the supply magazine 11 in an inclined plane, is maintained by the support rail 12 in this position during its journey to the downstream end of the magazine 11.

 In this regard, it should be noted that the movement from the upstream end to the downstream end of the strip 1 to be cut is carried out step by step.

 This step-by-step movement of the magazine 11 is of course coordinated with the duration of sectioning of the strip 1 introduced into the sectioning unit 200 so that the rate of the device is optimal and without dead time.

 It should be noted that in the case where there is no longer a baguette 1 in the supply store 11 for various reasons (operator absent, end of the stock of baguettes to be cut, etc.) the device stops automatically as soon as the end of the section of the last rod 1 introduced into the sectioning unit 200.

 To put the device back into operation, it suffices to introduce a rod 1.

 The strip 1, after having reached the upstream end of the magazine 11, is in a horizontal plane opposite the upstream end of the sectioning unit 200. In this position, the strip 1 to be sectioned is advantageously maintained and guided by the support rail 12 which will be erased as soon as the free end of the rod is introduced to make room for the support rail 12 arranged below.

 In order to avoid any unwanted fall, pivoting or turning over of the strip to be cut 1, the vertical plates keep it in the desired position. Furthermore, thanks to the elasticity and flexibility properties of the material from which these plates are made, such erase without damage to allow the passage of the support rail 12 during its course.

 If the support rail 12 which is present does not have a rod 1, it will be erased so as to leave room for the first support rail 12 which has a rod 1 to be cut.

 The strip 1 to be cut is in a position in which its end is introduced in the direction illustrated by the arrow F2 in the horizontal guide rail 31 of the cutting unit 200.

 The end 2 of the rod 1 introduced generally has irregularities as shown in Figure 1. This is the reason why it is necessary to initialize this end 2, that is to say to cut it according to a cut suitable for its subsequent assembly which, here, must be beveled.

 As soon as the end of the rod 1 to be cut is introduced into the rail 31, the holding wheel 26 is lowered into its active position to be in contact with the rod to be actuated 1 and to ensure its maintenance.

 The wheel 26 provides, by a coordinated rotational movement and combined with the rotational movement of the wheel 27, the drive over a determined length of the strip to be cut 1 along the rail 31.

 Here, FIGS. 4, 5 and 6 show the case where two wheels are used, the upper one 26 of which is a holding wheel which extends a short distance from the guide rail 31 perpendicularly to the latter so that the rod can freely enter this guide rail 31.

 In addition, to facilitate the movement of the rod 1, the stroke of the holding wheel 26 has advantageously been synchronized as a function of the nature and the shape of the rod 1 to be cut. Indeed, the useful face of the wheel 26 is advantageously covered with a flexible and smooth material which facilitates the movement of this rod 1. In the active position this useful face is necessarily applied against one of the faces of the rod 1. Consequently, whatever the thickness of the rod 1 to be cut, a suitable pressure is ensured which maintains this rod 1 sufficiently, without damaging it while ensuring its introduction into the guide rail 31.

 While introducing a sufficient length of strip 1 inside the sectioning unit 200 into the horizontal guide rail 31, the operation of a holding clamp 40 which coordinates the strip to be sectioned is coordinated As soon as the rod is supported by the clamp 40, the wheel 26 is raised to its erasing position and the clamp 40, the horizontal translational travel of which is determined and adjusted, causes the rod 1 along the guide rail 31.

 The end of the strip to be cut 1 is pushed in horizontal translation to a position in which it abuts inside the body of the clamp 52.

 This clamp 52 which in the erased or inactive position is arranged downstream of the guillotine 50 on the guide rail 31, opens to serve as a stop at the end 2 of the rod 1 to be sectioned inserted, then pushes back according to a fixed stroke this end in the direction of arrow F8 to a determined dimension.

 The retraction of the clamp 52 in translation is regulated by the information transmitted by the automaton as a function of the information transmitted by the encoder Indeed because of the attachment of the plate 47 to the body of the clamp 5 each retraction of the clamp 52 in translation horizontal causes a corresponding translation of the plate 47.I1 this results in a partial overlap by the plate 47 of the three cells 44, 45 and 46 of the encoder according to one of the eight possibilities represented in FIG. 12. Consequently since each of these possibilities corresponds to a position of the plate 47 and therefore of the clamp 52 the position of the strip to be cut 1 is adjusted by several successive translational movements of the clamp 52.

 It is therefore noted that this stroke is preferably studied so that in the desired pushed-back position the end of the strip to be cut is located under the cutter 50 at a position which allows cutting of this end 2 while limiting the resulting cutting as much as possible.

 In this position, the rod 1 is released from the clamp 52 which opens and returns to its original position. The rod 1 is held under the cutter 50 on the one hand the stops 51 ′ and on the other hand by the stops 51. These stops 5 and 51 are mounted movable and are moved from a low position erased and inactive to a high position and active in which they maintain the rod 1.

 As seen above, the opening of the clamp 52 and the release of the strip 1 of the clamp 52 are coordinated with the rise of the stops 51 so that the strip 1 to be cut is always maintained. Indeed, this is an essential condition to avoid any fall or sliding of the rod 1 of the guide rail 31.

 In addition, it is necessary for this rod 1 to be perfectly maintained during the sectioning operation in order to be sectioned correctly and to avoid any inaccuracy in the section which would cause defects in the components 4 of the articles 4 or in the frame 10.

 With the conditions of FIG. 8, this device is suitable for ensuring this holding function whatever the position of the rod and then of the components.

 However, it results from this section of the end 2 of the rod 1 during this initialization operation a short length cut according to the invention which is discharged directly through an orifice 67 located under the cutter 50. This evacuation is carried out by introducing a stream of pressurized air which, by blowing effect, releases this cutout towards the outside of the device.

 After this prior operation of initializing the end 2 of the strip 1 to be cut, the strip 1 can be cut by optimizing its section and minimizing the fall according to the invention.

 The rod 1 is released from its links 51-51 ′ under the cutter 50 and it is pushed back by the clamp 42 which has opened and positioned in masked time until a predetermined dimension where its end is in an applied position in abutment in the clamp 52.

 Simultaneously with this release of the rod 1, the position of the stop clamp 52 on the guide rail 31 is initialized and adjusted.

 Referring to FIG. 8, it can be seen that this device comprises an electric motor 60, the output of which is associated with a pinion 61 which meshes with a rack 63 horizontally integral with the drive jacks 64-65 of the clamp 52.

 It follows that the displacement, over a stroke determined as a function of the information transmitted by the information processing means, of the pinion 61 on the rack 63, positions the jacks 64-65 at a determined dimension and adjusts the stroke of the clamp 52 .

 These jacks 64-65 are held in this position by the action of the magnetic field of an electromagnet whose operation is coordinated with their placement in this adjusted position.

 Thus when the rod 1 is released from the supports 51 and 51 ′ in which it is located under the cutter 50, its end will be applied against the clamp 52 which has been opened. In this position, the rod is pushed back on the determined stroke along the guide rail 31 so that the rod 1 is again under the cutter 50 at a defined dimension which corresponds exactly to the length of the component 4 which is desire to obtain.

 As described above, the rod 1 is released from the clamp 52 in a coordinated manner with the positioning of the retaining stops 51 and 51 r.

 Under these conditions, the clamp 52 is again moved to its original position and the end of the rod 1 held under the cutter 50 is cut so as to obtain a component 4.

 It should be noted that if the logic requires it, the clamp 52, after each installation of the strip 1 to be cut under the cutter 50, can be moved to a different dimension. Under these conditions, this adjustment of the position of the clamp 52 on the guide rail 31 is carried out simultaneously with the cutting of the strip under the cutter 50, that is to say in masked time to avoid dead times which reduce the cadence of the device.

 In this case, the operation of the electromagnet is stopped so that the jacks 64-65, integral with the clamp 52, are again free and mobile. They follow the movement over an appropriate stroke of the pinion 61 on the rack 63 so as to be positioned and adjusted on a stroke which allows the length of the desired component 4 to be obtained. Of course, as soon as these jacks 64-65 are in the desired position, they are again maintained in the latter by putting the electromagnet into operation.

 It should also be noted that this positioning of the clamp 52 at a determined dimension is not necessarily carried out after each initialization of the strip 1 to be cut. Indeed, if the logic is such that the length of the last component 4 cut from the rod 1 has the same length as the length of the first component 4 from the other rod 1 to be cut, the clamp 52 remains in its position.

 The position of the rod 1 is precisely determined by the sensors 20-21 arranged on the cross member of the frame 14 of the supply magazine 11. If this system of determining the sound length of the rod 1 to be cut on the food store 11 is to optimize the section of this rod and limit the fall according to the logic of the device as it has been described.

 These sensors 20-21 make it possible, thanks to the information they transmit by conventional and known connection means, to determine the minimum length of rod that the device can cut by limiting the resulting fall.

 To allow maximum optimization of this device, the encoder 43, constituted by the plate 47 such as that shown in FIG. 11 associated with three sensors 4445-46, is integral with the clamp 40 determines the length of the strip to be cut 1.

 During the movement of this clamp 52, as a function of the logic over a determined stroke, the encoder 47 transmits information to the automaton as a function of the selective overlap by the plate 47 of the three sensors 44-45-46. This cover, according to the invention due to the particular conformation of the plate 47, is studied to correspond to one of the eight possibilities shown in FIG. 12.

 Consequently, thanks to the information collected by the encoder 43, it is possible to optimize the section of the length of rod 1 remaining to be cut since it is known exactly, from a determined length, the length of rod 1 remaining to be cut.

 After its section, the component 4 is supported by the articulated arm 70 by means of its clamp 71 as illustrated in FIG. 13.

 For this, still in masked time, the arm 70 pivots from a retracted position to a position facing the cutter 50. After the component 4 has been cut, this arm 70 descends, according to an appropriate stroke, while its clamp placed at its free end, opens so that it grasps component 4 and at the same time this component 4 is released from its supports 51 and 51 '.

 This arm 70 provided with component 4 rises according to a fixed stroke and it pivots on an angular sector determined by the control logic to be above a free support rail 74 of the storage magazine 73 called "intermediate". In this position, it descends to a position where it deposits the component 4 after opening its clamp on the intermediate magazine 73 in one of the free support rails 74.

 While the arm 70 is in this position, a movable stop 76, in vertical translation arranged opposite the rail 73 of the intermediate magazine 74, rises to come into position against this arm 70. This stop 76 is moved by an associated cylinder 77 to a link 78 fitted with a sensor 79 so that in the active position, that is to say in the raised position (represented in FIG. 15), it transmits information to the automaton on the position of the component in the intermediate magazine 74.

 In fact, thanks to this sensor 79, the automaton knows exactly the location of the component 4 that the arm 70 deposits and thus it is taken into management for obtaining the intermediate article 8.

 This arm 70, after having deposited its component 4 in the appropriate location, is released from the stop 76 which descends, it goes back up and goes to seek another component 4 which has just been sectioned.

 The other arm 80 mobile in rotation in masked time and synchronized with the first arm 70 searches for the components 4 on the intermediate magazine 73 and deposits them on a laying table 90 of a so-called "assembly" unit 300.

 While the first arm 70 takes the component 4 under the cutter 50, the second arm 80 is positioned opposite a support rail 74 which has the component 4 sought. This arm 80 descends over a determined stroke at the same time as the clamp 81 disposed at its free end opens. I1 takes this component 4 inside its clamp 81 which closes, rises and pivots on a determined angular sector to find itself in a position where it is opposite the go laying table.

 This arm 80 descends and opens its clamp 81 to place this component 4 at the end of the horizontal laying table 90. As soon as this component 4 is placed on this laying table 90, a movable stop 92, in vertical translation is raised to hold this component 4 as soon as it is released from the clamp 81. From the moment corresponding to the taking over of the component 4 by the stop 92 of the laying table 90, this arm 80 goes back up and goes to seek another component 4.

 Referring to FIG. 16, it can be seen that this laying table 90 has a longitudinal slot 91 which extends substantially over its entire length and inside which the stop 92 is movable in translation. This component 4 is supported by the clamp 93 movable in translation by a jack 94 which brings the component 4 from its installation position to a position called "pre-assembly".

 In this position, the component 4 is kept waiting to be supported by an arm 121 whose free end comprises a clamp 122 such as that which is more particularly shown in FIG. 18.

This clamp 122 comprises a body 123 secured to two fingers 124 and 125 which are articulated by links 126 associated with jacks 127 to allow the gripping and gripping of the component 4
In order to facilitate the maintenance and the guiding of the component as soon as it is gripped by fingers 122 and 123, the guide plate 134 covered with a flexible translate material under the action of a microverin between an erased position and an active position.

 As soon as component 4 is inserted inside the clamp 122, the spring blades 136 maintain body 123 and the fingers 124 and 125 of the clamp 122 in the position which ensures perfect retention of the component 4. In order to avoid unwanted movements of the clamp members under the action of mechanical stresses, the automaton controls the activation of an electromagnet which clamps the spring leaves 136 under the action of the magnetic field emitted. I1 results from this that the component is perfectly in a position allowing it to be put in place with a view to its subsequent assembly as will be described later.

 Referring to Figure 19, we see that this arm 121 is arranged on a carriage 120 which is mounted movable in translation on two parallel rails 111-112 between a retracted retracted position and an active position.

 We will not describe in detail the complex kinematics of the arm 121 associated with this carriage 120 which can be movable lon three degrees of freedom to recreate the movements of the operator during the assembly of the components 4 for obtaining the intermediate article 8.

 However, it should be remembered that this arm is movable in horizontal translation, in vertical translation and in rotation over defined strokes.

 As soon as the component 4 is in the pre-assembly position, the arm 121 is brought by the translation of the carriage 120 opposite the latter. In this position, it descends and opens its clamp 122 to take charge of component 4.

 As soon as it has taken over this component 4, the clamp 92 moves back, the stop 93 disappears and returns to its original position to maintain another component 4 which is deposited on the laying table 90 in the position of waiting.

 The clamp 122 pivots and presents the component 4a on a horizontal table 95 known as an assembly table (FIG. 20) inside the V-shaped part 97. Inside this part 97 the component 4 is advantageously placed exactly at the 'Appropriate location by the central holding slot 99 inside which its end to be assembled slides.

 After having deposited the component 4a inside the V-shaped part 97, the clamp 122 rises, pivots and is placed in a position where it is opposite another component 4b which has been brought into the pre-assembly position.

 The clamp 122 descends and supports the component 4a so that the stop 93 and the clamp 92, as described before, is erased again to support and maintain another component 4c which is deposited on the table 90 in the waiting position.

 The clamp 122 pivots, translates to bring the component 4b which it maintains on the assembly table 95. In this position, the clamp descends and deposits the component 4b in the V-piece 97 so that its end to be assembled is positioned opposite the end of component 4a.

 After placing the component in this position, the clamp 122 rises while a movable stapler, in translation between a low erased position and a high position, rises to staple the two ends of the components 4a-4b arranged opposite in the workpiece. V 97.

 As soon as this stapling operation is completed, the stapler descends to its low position and the clamp 122 advances, descends, takes charge of the two components 4a-4b assembled.

 The clamp 122 moves back, pivots and translates to place one of the ends of the assembly of the two components 4a4b assembled in the V-piece 97. After having deposited this assembly 4a-4b, the clamp 122 rises, moves back and translates to bring another component 4c to be assembled in the V-shaped part 97 according to the same kinematics as that which has been described previously.

 Thus in the case of a frame which has four sides 4a-4b-4c-4d as illustrated in FIGS. 22 to 26, to assemble all of the four components 4a-4b-4c-4d so as to produce the intermediate article 8, the clamp 122 pivots four successive times. Of course, the operations of placing the components in the V-piece 97 and of stapling are coordinated and are carried out in masked time to increase the rate and the productivity.

 It should be noted that the translation of the clamp 122 for bringing the components depends on the proper length of the component to be brought. This is the reason why this displacement is regulated by regulating the stroke of the actuating cylinders 130 of the arm on which the clamp 122 is arranged.

 To this end, these jacks are integral with a horizontal rack 131 on which a pinion 132 meshes with the output of an electric drive motor 133.

 Depending on the information transmitted to the motor by conventional connection means from the automatic, the motor drives the pinion 132 over a determined stroke so that it moves on the rack 131 on this stroke. Thus the drive jacks 130 associated with the arm 120 have a stroke corresponding to that determined as a function of the length of the component 4 to be assembled.

 This adjustment of the stroke of the jacks is not necessary for each assembly operation but depends on the logic which defines the appropriate component 4 for the production of a given intermediate article 8, that is to say four components assembled between them.

 After this assembly operation, as soon as the intermediate article 8 is finished, the clamp 122 removes this article 8 from the V-piece 97, moves back and deposits it on the hatch 140 which is in the closed position.

 As soon as the article is placed on the hatch 140 and the reception of this intermediate article 8, the clamp 122 rises and returns to take charge of a component 4a to be assembled.

 The hatch 140 opens and the article 8 falls by gravity on the upstream end of a conveyor 141. When the article is received on the conveyor 142 this article 8 comes into contact with the hatch 140 so that it turns on itself by pivoting and thus it occurs on the conveyor 142 on its external face.

 As soon as the article 8 is on the conveyor 142, a sensor transmits the information to the automaton by conventional connections so that the hatch 140 closes and is in a position where it extends the laying table 90 and 95.

 This intermediate article 8, in this inverted position, moves on the conveyor 142 to a movable barrier 143 in translation between a high erased position and a low active position. The automaton having transmitted the information of the presence of this article 8, this barrier 143 is lowered so that the article comes into abutment against it.

 In this position, the article is supported by a rack associated with lateral stops which adjust its position so that it is substantially parallel to the travel plane of the conveyor 142.

 To coordinate the rest of the making operation and in particular the fitting of the glass, the barrier 143 includes a sensor 146 so that, when the article 8 comes into contact with this vertical stop, it transmits information by means known to the machine.

 This automaton controls, in masked time, the descent of a second barrier 144 so that as soon as the article 8 is repositioned, the first barrier rises, releasing the article 8 which comes into the abutment position of this second barrier 144 while the first barrier 143 descends to confine the article 8 inside the space between these two barriers 143-144 descended.

 The second barrier 144 includes a sensor 146 which as soon as the article 8 is in the abutment position against the latter, transmits information to the automatic device.

 As soon as the article is placed between the first two barriers 143-144, a carriage 150 movable in vertical translation moves to position itself according to the information transmitted to it by the automaton above the glass stack 147 corresponding to the dimension of the intermediate article 8.

This carriage has an arm fitted with suction cups 151 which descends to take one of the glasses from the appropriate stack 147 and then rises.

 The carriage 150 moves from the store to a position in which it is located opposite the article 8. This arm descends and deposits on the article 8 the glass 5. Then it rises and translates to the store where , according to the information on article 8, the position of which is adjusted to the level of the first barrier 143, it is positioned above the appropriate glass stack.

 As soon as the glass is placed, the second barrier 144 rises and the article comes into the abutment position of a third barrier 145 which has just come down. Of course during this time the first barrier 143 rose to release the article 8 which has just been repositioned.

 This third barrier 145 also includes a sensor 146 which indicates the presence of the article 8 in the stop position so that the automaton manages this various information to coordinate the raising and lowering of the barriers 143-144-145. So as soon as an article 8 is introduced between the first two barriers 143-144, the third barrier 145 rises so that another article 8 is released.

 Item 8 with its glass 5 is conveyed on the conveyor to a manual garment station. The operator takes the article, possibly replaces the glass if it is not correctly placed and deposits one. back plate 6 support made of cardboard, wood, synthetic material, metal, etc. To complete the making of the final article, the operator can introduce other components such as an engraving, a drawing or any other advertising image support or not between the glass and the external support.

 Of course, this operation can be obtained mechanically by appropriate means such as an articulated arm arranged to ensure the positioning of the support from a storage magazine.

 As soon as the operator has finished his assembly operation, he deposits the final article 10 on a conveyor 153 which transports it to a station for placing and immobilizing the constituents.

 It should be noted that the operator who deposits the constituents of the article simultaneously checks the quality of the final article 10 so that he can possibly sort the articles and remove some of them which do not have the required quality. Likewise, its function is to check the perfect functioning of the entire device and to introduce the rods 1 into the supply magazine 11 to avoid stopping the machine.

 However, this possibility of removing articles which do not comply with the quality criteria requested, requires that a new logic take into consideration the final articles of which the components are secured and immobilized.

 This is the reason why the final article 10 which comprises all of the constituents (external glass 5, rear support plate 6 and the like) comes into abutment against a barrier 154 lowered from the conveyor 153. This barrier 154 on the one hand comprises a rack provided with two vertical stops so that they adjust the position of this article substantially parallel to the plane of movement of the conveyor and on the other hand a sensor which transmits information on the presence of this article 10 and on its dimensions.

 As soon as article 10 is repositioned and taken into consideration by the new logic, this barrier is raised, releasing the article which opens onto a horizontal plate 166 movable in rotation.

 When the article 10 is in this position, a carriage 150 movable in translation moves from a retracted position to a position in which it is above the article to be assembled. This carriage has on its free end three guns 162-163-164 for positioning fixing members. These three guns 162-163-164 are advantageously movable in lateral translation to allow an adjustment of the positioning of the fixing members as a function of the proper dimensions of the final article. Similarly, it is possible to delete one of these guns if the dimensions of the frame do not require its use.

 The arm 160 descends while the spacing of the guns 162-163-164 is adjusted in order to present the guns in the appropriate locations. that movable mounted stops between an erased position and an active position take charge and retain the sides of article 10 on which the fixing members will be placed.

 Then the gun (s) 162, 163 and 164 are lowered and they set up the fixing members on one of the sides of the frame. As soon as one is assembled, the arm 160 is raised while the plate is pivoted so that there is another side of the frame to the guns 162, 163 and 164.

Of course, this operation is carried out here four times to assemble the four sides of the frame (Figures 29 to 33).

 As soon as this operation is complete, the plate again pivots the frame, the stops return to their erased position, so that the frame 10 which is no longer maintained opens onto the upstream end of the conveyor 170. This conveyor 170 transports the frame 10 to a station for installing protective corners at each of its edges.

 This positioning of the corners can be carried out manually or in a more elaborate form of automation by mechanical means.

 For example, it is entirely possible to have arrangements similar to those of the installation of the components fixing members associated with an articulated arm which would deposit from a stock, these corners 9 at each edge of the frame 10. Of course, the person skilled in the art knows other alternative embodiments from suitable mechanical arrangements which make it possible to produce this deposit of the corners.

 As soon as these corners 9 are deposited at each of the edges of the frame, the operator places the frame on the upstream end of a conveyor which drives it inside a device of a conventional and known type of implementation. protection and packaging film. This assembly unit comprises two devices for placing a protective film and packaging in synthetic material each associated with an oven which are conventional so that they will not be described.

 To increase the throughput of the machine, two film placement devices are used which each pose a film of different dimensions. In order to optimize the management of the film placement devices and to limit the falling of films, the operator or the logic directs the frame in the film placement device according to the dimensions of the frame 10 or its orientation. most suitable film.

 At the outlet as soon as the frame 10 is wrapped, it emerges at the downstream end of this conveyor. It leads to a packaging station for a packaging unit 600. In fact, as soon as these frames are packaged, they are intended to be marketed either individually or in batches.

 This station of a conventional and known type includes a plate or a reception table where the wrapped frames open. An operator performs a final product quality control operation and deposits these frames in containers (boxes, cartons, various packaging, crates, etc.).

 Of course, it is entirely possible to use automated means to perform this operation.

 It goes without saying that the invention is not limited to the single embodiment which has been described above. For example, we will not depart from the scope of this invention by any modification of arrangement allowing total or partial automation of the different units or of the entire device
