Description

 DEVOLUTION PROCESSING DEVICE

OF INVESTED ITEMS

OBJECT OF THE INVENTION

The present invention, as expressed in the description of this specification, refers to a device for processing the return of invented items, which provides a series of relevant and advantageous features in this sector of the industry. FIELD OF THE INVENTION

The device that constitutes the object of the present invention, is conceived as an area or dock for processing articles of varied nature and geometry (boxes of chrome, chewing gum, baubles, large promotional cards with videos and recorded cassettes, newspapers, magazines, etc) that it is applied peripherally with respect to a recognition and classification machine exclusively trained for the treatment of publications such as magazines, newspapers and the like; machine whose classic example of application is by the distributing companies of periodical publications, to control the payment of the invented copies that are returned to it by the retail outlets. Basically, the objective of this now recommended device is to facilitate the precise, continuous and synchronized control of all the invented, generating a true automated industrial management process in which human decisions are minimal, and labor is optimized.

These machines preferably manipulate flat objects such as magazines and the like, for their classification preceded or not by the recognition and identification of their printed covers, or associated code. Although it can be applied more generally However, the object of the present invention is particularly intended to improve the efficiency and functional reliability of a machine for recognition, identification and classification of a huge amount of invented press that has to be processed in order to refund customers of the distributor or publisher company equipped with such a machine.

STATE OF THE PREVIOUS TECHNIQUE In the field of this invention, machines with capacity are known exclusively for the recognition and classification of newspapers, magazines and the like, which have a loading area on which the specimens are classified one by one and they are transferred until they are passed through a recognition station that explores the covers of the same, contrasting them with previously "learned" models, following whose station the specimens access a classification zone in which there is a plurality of doors of selective expulsion of the same. i The specialization of these machines to the treatment of the aforementioned publications does not allow them to satisfactorily meet the needs of a distribution company that, together with newspapers and magazines, traffics with promotional offer cards that include recorded audio and video tapes, etc. and articles that we will designate as "atypical" and that offer a great diversity of geometries, for example boxes of chrome and baubles. These atypical and promotional items can account for a considerable percentage of the total invented items returned to be paid, and the simple fact of having one of these machines that does not manage them, only partially solves the distribution management problem.

German patent DE-899174 describes a system for transporting and classifying flat objects in the fact that these objects are transferred on tracks or sliding rails by means of the thrust made by dragging pythons that are jointly attached to a motorized endless belt; it is also specified that the sliding bed is inclined transversely towards a longitudinal side of the transport, in which there is a sliding edge or profile for the lower edge of the transported flat object; it is also specified that said transferred flat objects can be removed or expelled by said longitudinal side of lower dimension, using for the purpose thrust means that act transversely to the flat object in question and that are established in correspondence with a plurality of ejection or exit doors to which corresponding stacking deposits are associated.

When the transport and classification of such flat objects has wanted to be integrated continuously with the function of prior recognition and identification, the same general concept of machine described in said Patent DE-899174 has been applied, with only the additional incorporation of a, if known, an optoelectronic station or station capable of recognizing and identifying the printed covers or covers of said flat objects; in such a way that, these flat objects are sequentially transported through said optoelectronic station and then classified according to the verified recognition and identification. This is the case of the object included in US Pat. No. 4,042,113, which refers to a machine expressly intended for the recognition, identification and classification of magazines; In this US Patent 4,042,113 also flat objects or magazines are moved by dragging endless belt along a bed inclined towards one of the longitudinal sides of the transport, east side where there is a sliding edge or profile on the one who supports the back of the magazines that are being dosed one by one in an initial reception or loading area; In their progress, these journals pass through said optoelectronic station and then access the classification section, where media that act transversely on the magazine, separate it from the inclined transport bed and, by gravity, selectively falls into one or the other of the multiple possible deposits stackers; This particular execution of US Pat. No. 4,042,113 contemplates the substitution of drag pins by the effect of direct contact friction of the magazine on the transversely inclined endless belt, in combination with magazine dosing means. which establishes the distance between successive magazines, as well as for the expulsion of the magazines, diverting auxiliary means have been incorporated that facilitate the orientation of exit towards the corresponding stacker tank.

In this specific application to the case of magazines and other flat or similar objects, it is essential that the magazine be automatically and infallibly taken to an operational position that ensures correct recognition and identification by the optoelectronic station and an incident-free transfer to its location. Exit door preset in the classification zone. The solutions provided in this regard so far are not fully satisfactory.

Numerous types of feeders or dispensers of publications are also known today, and all of them discriminate or separate a specimen from a stack of them; Although in the majority of feeders the separation is total, there are others of partial separation, that is, each copy is on top of another in an overlapping manner.

A characteristic common to all of them and that is fundamental for their operation ^, is that all copies of the cell to be dosed must be homogeneous: same or very similar dimensions, equal degree of flexibility, etc. Thus the most common ones dose the lowest copy of the stack with an operating philosophy designed in some cases to take advantage of the flexibility characteristics of the copy, in others precisely the opposite (cardboard pastes), in others by the thickness and stiffness of the loins, etc.

We find some dosers of copies that can be very effective for one type of publication but contraindicated for another type and, in all cases, inapplicable for the simultaneous dosing of two types of publications.

Another aspect to keep in mind is that at present the publications have plastic wrappers that keep inside different gift items: videos, C.D., figurines, etc., which in general we will call "gadgets". These gadgets make the surface of the specimen not flat and also have a variable and unexpected geometry. Traditional dispensers do not adapt to this circumstance.

EXPLANATION OF THE INVENTION AND ADVANTAGES

Faced with this state of affairs, the new device now recommended, a processing spring applied as a peripheral of a typical periodical processing machine, will allow the integral management of the invented, atypical ones included, in a precise, continuous, synchronized way and automated, with minimal human intervention and taking advantage of the machine's own control computer that is connected to the central computer (HOST) of the distribution company; in such a way that, the set of said new processing dock, machine and HOST constitute a true system of integral management of the return of invented. To this end, the new spring device Processing includes:

- an unpacking station for the invented items to be processed;

- a computer for entering an identification code of each package of goods, which is associated with said unpacking station and connected with said control computer;

- a first conveyor of invented publications that flows into said machine between said unpacking station and a dosing station for the copies of said publications, adjacent to said loading area of the machine;

- an end-of-dose discriminator, associated with said manual or automatic doctor position; - a second atypical article conveyor that runs functionally parallel to the machine, from said unpacking station to an auxiliary operator-assisted recognition post and located in transverse operational correspondence with the first door of said sorting zone and which is intended to expel unrecognized specimens; a third conveyor of unrecognized specimens that extends transversely to the machine from said first door to said auxiliary post; - an optional fourth conveyor of extemporaneous examples that extends transversely to the machine from a second door provided for that purpose in said classification zone to said auxiliary position;

- associated to said auxiliary position and connected to said control computer, a computer for processing invented atypical articles, of unrecognized copies, and optionally, of extemporaneous copies;

- a fifth conveyor that extends between said auxiliary post and a wrapping means and storage with a pre-storage carousel of unrecognized and atypical for manual classification;

- a printer and, optionally, a printer destined to assign identification code for unrecognized and extemporaneous people who are respectively associated with said conveyors and connected with said control computer.

The new processing device thus constituted works as follows: The unpacking station operator receives the package of goods, with his return receipt from a specific retailer (customer); separates the typical specimens to be processed by the machine from the atypical ones; enter the delivery note data in the job computer; Place the typical copies on the first conveyor (transverse to the machine) and atypical items (with said return delivery note) on the second conveyor (parallel to the machine). Typical examples end at the dosing station, being dosed on the loading area of the machine, and after being subjected to recognition, they reach the classification zone where they are expelled by a predetermined multiple doors according to the program established in the machine control computer; the copies, which due to deterioration or other causes, are not recognized, are expelled by the door immediately after the recognition station; Likewise, extemporaneous copies (returned outside the established and programmed time frame) will be expelled through the second door. Said unrecognized and extemporaneous copies automatically pass to the respective third and fourth transporters that take them to an auxiliary operator-assisted examination post, where they converge with the atypical ones arriving by said second transporter. The specimens and atypical treated in this auxiliary position, they are deposited in the fifth conveyor, which transfers them to the carousel where they will be manually wrapped, or to the automatic means of wrapping and final storage. Depending on the volume of atypicals, the existence of more auxiliary stations along the second conveyor is planned, as detailed below and illustrated in the drawings.

According to the invention, said first and second conveyors are preferably integrated by a plurality of sections provided with independent tractions and, except for the first section, the other intermediate sections and the final section have presence sensors associated therewith which they detect the occupation or not of the section by items in process and are connected to a unit that governs their independent tractions, ordering the activation of a section when the next one is free and keeping the first section activated except when all the successive sections are occupied.

On the other hand, said third conveyor has three zones or operating positions differentiated: an initial or receiving position of the unrecognized copies delivered by said first door of the machine classification zone, a central position that is occupied by the group of said copies received in the initial zone when the package of origin of them has been processed, and whose central zone is associated with said printer that incorporates to this group of unrecognized persons an assignment code assignment code, and a final position or delivery to said auxiliary position, which in the next advance of the transporter is occupied by said group of unrecognized; said conveyor being combined with said push button to advance a position each time it is pressed; said printer being governed by said control computer to act each time a group of unrecognized occupies said central position

Likewise, said optional fourth transporter for extemporaneous specimens has three successive zones or operating positions differentiated: an initial reception position for the copies delivered by said second door of the machine classification zone, a central position which, by means of an advance unitary, it is occupied by the group of copies received in said initial position as coming from a certain package of processed goods, and whose central position is associated with said printer that incorporates to this group of extemporaneous ones an identification code assignment note, and a final delivery position to said auxiliary position that is occupied by said group of extemporaneous in the next unit advance of the conveyor; the traction of this conveyor being connected to advance one position each time said dosing end button is pressed; and said printer being governed by said control computer to act each time a group of extemporaneous occupies said central position.

As noted above when there is sufficient proportion of atypicals, it is envisaged that at least one of the sides of said atypical conveyor, there are additional auxiliary reconnaissance posts provided with corresponding additional computers and located in correspondence with one of the multiple tranches of said conveyor.

Since said fifth conveyor has a trajectory coinciding with that of the atypical conveyor, it is provided that the first consists of a lower section that extends below said conveyor and an ascending section that feeds said carousel; with the particularity that said lower section will extend longitudinally to the extent necessary to meet each and every one of the auxiliary posts implanted and through of respective dosing ramps of the articles already recognized in them.

As can be seen from the above, the new device created carries out a continuous and exhaustive processing of the entire package of products, a part autonomously by the machine itself, and the rest (atypical, unrecognized and extemporaneous) in auxiliary positions of recognition attended by the operator, but interconnected with the machine control computer, obtaining, in short, a total management of the invented.

On the other hand and in relation to the doors that the sorting area of the machine has for the expulsion of the validated specimens, the optional use of simple collection drawers that store using the gravitational action and a double inclined bottom is provided or, the use of controlled discharge devices formed by a transport element that feeds a first receptacle that, when it reaches a predetermined number of copies, is automatically emptied onto a second receptacle from which they are taken for wrapping by means Manual or automatic.

The elements to be processed, generically designated as magazines, are transferred in the manipulative machine, one at a time by members and bidders in solidarity with an endless belt and resting on a bed that is inclined towards one of its longitudinal edges. , in which there is a sliding profile for the spine of said magazines, so that each magazine is dosed on a reception area of said inclined bed and is transported through an optoelectronic station for recognition and identification of its cover , to finally reach an area of classification or expulsion in which there are a plurality of doors of selective discharge that they have associated ejector means that transverse the magazine transversely, separating it from the inclined bed.

According to the invention, an effective and reliable treatment of the magazines is achieved by providing simple means so that they are naturally and automatically brought to their ideal operating position and so that the transfer takes place without incident; All of which will improve the performance of the machine, and this has a special significance when, as usual, these machines have to process huge amounts of magazines that frequently produce work overloads.

Another object of the invention is a simple and inexpensive device for supporting the endless belt or transversely inclined bed which facilitates its replacement.

According to the invention, there are first means prior to the functional entry into said optoelectronic station and that provide the automatic correction of the transverse position of the magazine, by its gravity slipping on the inclined bed, until its spine is applied on said profile. of sliding; second retaining means of said correct transverse position of the magazine; a third means, also prior to said entry, propitiators of the automatic correction of the longitudinal position of the magazine by its backwardness to the immediately subsequent pusher block; fourth means of fixing the flatness of the cover of the magazine for processing by said optoelectronic station; Fifth anti-descent support means of said inclined endless belt; sixth means in said ejection zone between said optoelectronic station and the selective expulsion, guaranteeing the anti-flipping of the magazine cover; seventh means, also in said ejection zone between said station and the selective expulsion, guaranteed- beef roll anti-roll of the magazine; eighth ejector media from the magazine that combine the actions of two independent actuators, with double-bevel deflector configurations and exit ramp; and a ninth means of access to the endless belt through the inside of the frame of the machine for its assembly and maintenance. For what has been said in the previous section, in accordance with another of the objects of the present invention, the problem of dosing one by one previously stacked copies, when these are homogeneous and without gadgets, is sufficiently solved. However, there are cases such as packages that send outlets with the return of unsold publications, in which the copies that make up those packages are completely heterogeneous. When it is intended to carry out the control of the return by automatic procedures, by machines that identify the cover image or that read codes (bars, color, binaries, etc.) it is necessary to have feeders that unit dose the unit to the machine in issue to significantly increase its performance. •

Therefore, the automatic feeder that can be used in the device for the processing of the return of invented items, such as the one described above and which can also be used in other different processing facilities, meets the following specifications:

- It is capable of dosing consecutively specimens of different sizes and / or consistency. - It is capable of dosing copies with gadgets.

- It is capable of dosing homogeneous specimens.

- it has synchronization elements with the transport system of the return control machine (or other type of machine). - it has interface elements with the software of the return control machine.

To achieve these prerogatives, the automatic feeder constructed in accordance with the invention, is constituted in general lines, by a hopper receiving the specimens to be dosed, having a bed or lower plate inclined and grooved, establishing the bearing surface of the loins. Laterally, the examples are guided in a fixed reference wall and rest on a front wall that is mobile and that is related to a pneumatic cylinder, as we will see later.

The entire stack of copies is supported on the rear movable wall and the unit extraction is carried out by means of a vacuum suction cup, which is equipped with a "reciprocating" movement that is controlled by an electronic device, through the which synchronism is achieved to match the forward movement with the action of the suction cup, as well as the movement of the mobile wall of the hopper in the appropriate distance to guarantee the contact of the suction cup with the pile or package of invented .

The existence of a device separating the spines of the copies or magazines, consisting of several elements placed in the front part of the hopper to discriminate the specimen to be extracted and facilitate its dosing, is also planned.

Regarding the vacuum cup, we can highlight the fact that its structure is formed by a housing connected to the tube connected to the depressor, having an external grid that comes into contact with the specimen to start the suction in a homogeneous, optimized way by the existence of an elastic tongue that borders the suction cup.

Compensating elements for deformation of the stack of specimens are provided, in the current case that the loins of them have a tendency to slide towards the front part of the grooved plate at the bottom of the hopper, thus leaving the battery with its base wider than the top. This fact is frequent with piles of large number of copies, but also when there are few and are vitiated in that regard. To avoid this, the automatic feeder includes in the mobile plate a pusher plate that adapts to the stack of copies with the help of a pneumatic cylinder.

10 When the last specimen of the battery disposed in the hopper has been removed, a sensor detects it and commands the backward movement of the mobile plate to its previously programmed initial position according to the size of the batteries that are waiting to be processed.

^' .. ^" An electronic device, based on vn? LC or on a microprocessor board or similar, controls all the movements required by the automatic feeder. Using a control software, the status of the different sensors is analyzed so that

From the conditions imposed on them, the corresponding solenoid valves that trigger the movements of the pneumatic cylinders responsible for the movements are activated.

The automatic feeder that contemplates the

In accordance with the invention, it is of special application in the dosing of copies with which automatic machines are fed to control the return of invented publications. These automatic feeders considerably improve the performance of such automatic machines. Inside

30 of the process of loading copies, the following aspects must be taken into account:

- the return of invented copies well organized by packages, each identified by a code indicative of its origin.

35 - each return package consists of heterogeneous specimens mixed together.

- the copies must be loaded separately and unitary to the return control machine, so that the reading system can identify each copy.

- Prior to loading the copies of a package, the identification code of the package must be communicated to the return control machine to relate its content to its origin or sender. - It is usually customary for the transport system of the return control machines to have elements that push or drag each specimen. Therefore, the dosing has to be carried out in the space between two pushers, which means that there must be synchronization between the load and the transport element.

Among other features we could mention the one that foresees the change of the code of the package to be processed, due to customer change. There is an electronic communication between the feeder control system and the return control machine. The latter is the one that knows the codes of the different packages. Therefore, upon receiving, by the feeders, an electrical signal, each time the last copy of a feeder is ejected, the return control machine makes the corresponding change of package code, to assign the next copy to the corresponding code.

The separation between the last copy of a feeder and the first of the following is programmable depending on the procedure used by the return control machine to make the code change. The start order to each feeder is carried out from the return control machine through the same electronic communication. In this special application of the automatic feeders, two of them are used, thus placing the operator in the middle of them. When the two feeders are unloaded and the return control machine has the corresponding package codes for each one, a pilot is lit next to the feeder that must first be loaded, so that there is no loss of sequence.

Each feeder has a sensor that activates with the passage of the pusher plugs of the transport system of the return control machine, so that the extraction mechanism of the specimen is synchronized with the passage of said pusher stud.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the numbering adopted in the figures, we can see how the device for processing the return of invented items, which the invention proposes, allows the integral management of invented items and is schematically represented in Figure 1, applied to a machine recognition and classification of magazines, newspapers and the like, which is controlled by the computer 5 connected to the central (HOST) of the user (distribution company that must manage the returned items, for payment to the retailer); and whose machine 1 also includes the loading area 2 on which the copies have to be manually or automatically dosed, the recognition station 3 thereof and the sorting area 4 provided with a first ejector door (4.1) for the copies Unrecognized, a second door (4.2) for extemporaneous copies, a plurality of doors (4.3 to 4.n) for the selective expulsion of copies that have been recognized by the machine and are also in the period of return (copies validated).

Constitutively and functionally the recommended device consists of the following:

In the unpacking station 6, the retail package of each retailer is removed, separating the publication copies of the atypical articles; In the computer 7, the identification data of the return receipt and of each package of inventories are introduced (by keyboard, bar code, etc.), which are passed to the computer 5 at the moment in which its effective processing will take place; the copies are placed in the initial section 8a of the conveyor and the atypical ones in the final section of the conveyor 11. Two successive packages can have the same identification and in the processing a stack of codes is created in this computer 7 so that the superior is that of the package closest to machine 1 (or to position 12); when the discriminator 10 acts, the first register of the stack goes to the computer 5 so that when starting a new dosage the data is already in the machine without typing them.

The conveyors 8 and 11 are integrated by several sections (8a, 8b, 8c) and (lia, 11b, 11c) of the continuous band type that can be operated independently and equipped (except the first 8a and lia) with presence sensors (barrier photocells) and of an electronic control (PLC), in order that each section (8b, 8c) and (11b, 11c) advances whenever there is no occupation in the precedent since the first section (8a and lia) is always underway except if all others (8b, 8c) and (11b, 11c) are already occupied. In this way it is possible to eliminate empty spaces between two successive packages, the dead times of the operators waiting for the package and, at the same time, it is achieved that the sections closest to the machine 1, as the auxiliary position 12, are always occupied. avoid the sliding of the packages, the band has a high adhesion surface; Y To ensure good continuity between successive sections, the tractor and idler rollers are small in diameter.

When the specimens reach the dosing station 9, the identifying data entered in the computer 7 have already passed to the computer 5 of the machine 1, the result of a previous action on the button 10 at the end of the dosing of the preceding package; the dosing is then carried out, one by one, of the specimens on the loading area of the machine 1; After completing the dosing of the package, said discriminator 10 acts, resulting in the code jump corresponding to the next package to be dosed in machine 1 and to be processed in the rest of the installation.

At the same time, the atypical ones progress through the conveyor 11 until reaching the auxiliary position 12, where they arrive accompanied by the retailer's delivery note so that the operator enters (by keyboard, bar code, ...) the corresponding code in his computer 13. When significant volumes of atypicals are expected, additional auxiliary posts 20 and corresponding computers 21 are implanted, preferably on the outer side of the circuit formed, although it is also possible on the inner side, which will act at their own pace.

In said auxiliary position 12 the unrecognized and the extemporaneous also converge for processing. The transfer is, respectively, carried out by the conveyors 14 and 15, which have the same operation consisting in that their light is subdivided into the three positions, initial (14a, 15a), central (14b, 15b) and final ( 14c, 15c) which are successively occupied by the examples in process. In the initial position (14a, 15a), the specimens from an invented package are accumulated until, with the action of the discriminator 10, it is first produced that the conveyors (14, 15) advance one position causing the specimens (irrecono - cidos and extemporaneous) become the central position (14b, 15b), second, that the machine 1 computer communicates the package code to the printer (18, 19) and third, the printer (18, 19) issues a ticket with said code and incorporates it into the group of copies; in the next advance, the final position (14c, 15c) in which they are in a position to be processed in said auxiliary position 12 will be reached.

Copies processed manually at auxiliary station 12 (and similarly at stations 20) are through the ramps 22, dosed on the lower section 16a of the conveyor 16 (which runs under the conveyor 11) to continue along the ascending section 16b that in this case, delivers them in carousel 17 where they wait to be classified, manually wrapped and stored, but that could also be delivered to an automatic wrapping and storage train.

As regards the recognized specimens, they are selectively ejected through the doors (4.3 to 4.n) of said classification zone 4. The collection can take place in simple drawers 23 with a double inclined bottom that favors automatic sorting. to of the copies; or, in controlled discharge devices 24 constituted by a transport element 24a (of bed preferably inclined to favor said arrangement) that places the specimens in the first receptacle 24b until accumulating a predetermined amount, at which time they are passed automatically to the second receptacle 24c, from where they will be collected for packing and storage.

The auxiliary computers 13 and 21 are expected to pour their processed data to the computer in the realization of a single joint document of the total return of a customer. Obviously, the execution of the device is susceptible of partial realization and for example, if the user does not require atypical discrimination, this part of the device can be eliminated.

With special reference now to figures 2 to 14, the magazines 55 are dosed one at a time over the recession zone 25a of the transversely inclined endless belt 26, ensuring that they fall between two successive transverse plugs 32, but without careful care , so it must be provided that the spines 55a are not in principle supported on the sliding profile 28 and that the magazines 55 are rotated and away from said profile 28, even on horseback from the transverse position of one of said studs 32. In such disorderly positions it is not possible for the optoelectronic station 25b to perform its recognizing and identifying function of the covers of the magazines 55, but that the ideal position for this purpose must be that the magazine 55 circulates with the Loin perfectly supported on the slide rail 28 and in a flat state so that the cover can be correctly "read".

To achieve this (Figures 2 and 4 to 6), the above-mentioned first, second, third and fourth means characterized by this invention are intended.

Thus, said first means, correctors of the transverse position of the magazine 55 on the inclined bed of the endless belt 26, consist in that: this endless belt 26 has its sliding surface; the pusher members 32 in solidarity with said endless belt 26 are transverse blocks 32 which have the particularity that they only extend in a narrow lower strip of approximate width to a part of the width of the endless belt 26, as well as that these studs 32 have on their upper face a bevel 32a which at its upper end is born at the level of the surface of the endless belt 26 and extends to approximately the center of said face upper of block 32; and there are devices that suppress static electricity from the surface of the endless belt 26, distributed along its length. That is, all of this is intended to facilitate the slipping by gravity of the magazine 55 until its spine 55a is attached to said profile 28; special mention is given to the studs 32 which, due to their length and beveling, not only favor said slippage but also allow the return of the endless belt 26 to be verified (figure 6) on rollers 31 that only need to be lowered in a short section of its length, which is enormously advantageous (for example, allows tension rollers to be arranged) compared to the hypothetical case of full-length cross-sections of the endless belt 26. As regards said second retaining means of the correct The transverse position of the magazine 55, consists of a strap 37 located between the slipping profile 28 and the lower edge of the endless belt 26, in order to prevent the transverse sliding of the magazines by descending slipping of the spine 55a.

And with respect to said third correct means ¬ of the longitudinal position of the magazine 55 on the inclined bed 26, they are longitudinally overlapped on said strap 37 and are operatively located between the sliding profile 28 and the beginning of the belt 26 and are the following: a retractable lifting device 34 of the spine 55a of the journals 55 that is normally shown by the antagonistic action of a spring 34a which yields elastically by the weight of the magazine 55, causing a combined action of the frictional and gravitational effects which causes the automatic delay of the issue of magazine 55; a vacuum suction cup 35 of Venturi effect that slows the advance of the magazine 55 until it is reached by the beveled block 32 that follows it; and a retainer strap 36 having intensity regulating device 36a and acting on the spine 55a of the magazine 55 in a previous and overlapping manner under the beginning of said strap 37 slowing the advance of the magazine 55 by increasing friction, until said reach is produced by the pusher or chamfer 32 .

The fixing of the flatness of the cover of the magazines 55 prevents a bad reading of the cover if it is lifted by deterioration of the specimen, by defective dosage, or by turbulence of the air, and this flatness is achieved by means of said fourth means, which consist in: a flipper fin 38 of said cover; a blower 39 of adjustable intensity which is located after said flip-flop fin 38, directed obliquely on the cover and activated by a sensor that detects the beginning of a new specimen; an air curtain 40 extending transversely across the width of the endless belt 26, has intensity regulation and is located next to said oblique blower 39 producing a continuous air flow inclined in the direction of advance of the specimen; and presser plates 41 which are located next to said air curtain 40 and are applied to the front cover in its advance through said electronic station 25b. The flip fin 38 is attached to the slide profile 28 of the spine 55a and has sufficient length and height to return to its natural position, covers that circulate completely open, even flying over said slide profile 28. The oblique blower 39 acts on the covers which try to lift the flip fin 38 already exceeded, and is activated by an electrical signal that comes from said sensor.

Given the transverse inclination of the endless belt 26, in order to effectively counteract its tendency to descend, according to the invention said fifth means are provided, which consist in that, along the upper edge of said endless belt 26, it is fixed a longitudinal block 27 whose bottom face is applied by both sides seen and hidden from the endless belt 26 on a plurality of bearings 43 supported on respective supports 42 anchored on the fixed frame of the machine 25. This support device is provided to be hidden by a cover profile 44 which will be discussed later, when dealing with the cover 46 anti-roll cover.

At the exit of the optoelectronic station 25b, the classification zone 25c is entered, where it is necessary to continue trying that the magazines 55 circulate in the correct position and without interference or arrests.

In this sense, it is necessary to avoid on the one hand, that due to turbulence of air, or vice of form, the covers turn over the sliding profile 28, exceeding it, since they would trip over the exit trays

52 and would interfere with the normal course, causing serious malfunctions in the processing of the invented magazines.

To this end, there are said sixth means, which consist of a grid 46 that can be made by weighing which is formed by stringers 46b that extend longitudinally on the endless belt 26 at a low height, adjustable with respect to said cover, and by crossbars 46a in cantilever whose feet are articulated to the static frame of the machine 25 by corresponding balancing axes 47; it is provided that said tilting shafts 47 of the grill 46 are located on a covering profile 44 of said means (27, 42, 43) of anti-lowering support of the endless belt 26 corresponding to the exposed face thereof, whose covering profile 44 is provided with corresponding supports 45 with respect to said supports 42. On the other hand, it is necessary to prevent slipping profile 28, those specimens in which the spine 55a has winding vice, can slip and overcome; for this, said seventh loin anti-roll means 55a of the magazine 55 consist in that: along the sliding profile 28 in said ejection zone 25c, there are retractable and retaining tabs 50, arranged one after the other and each associated with an exit door 52, whose tabs retainers 50 are projected operatively towards the center of the inclined bed 26, being flown over the path of the spine 55a, sliding on said sliding profile 28.

Co or said retaining flange 50 has to be retracted to verify the voluntary expulsion of the magazine 55, said eighth ejector means of the magazine 55 consist of: an ejector blade 48 which on ^* -u surface, active has longitudinal bevels -i8ε, in his er.t sm -rasa ec r. uas above, and transversal -tZ-h, εr. sc :: .- ^' - * -.riar.-εάo towards the axis of the sir.fi ^** tape. ^** . one ; an _ ^{** '} .. ^* actuator 49 of said ejector blade 48 between a non-active retracted position and an active position that substantially reaches the level of exceeding of said sliding profile 28; a second actuator 51, acting in combination with said first actuator 49 and which is associated with said retractable retaining flange 50 operating between said hovering active position and a retracted ejection position of the magazine 55. To prevent retracting a flange 46 downstream , could constitute a place of fortuitous attachment at the exit of the copy; it happens that said retractable retaining tabs 50, at its downstream end, have a triangular expansion complement 50a of its flown edge, whose protruding vertex of said complement 50a is establishing continuity according to the retaining overhang of the next flange 50 downstream . The actions of said actuators (49, 51) are combined (figures 13 and 14) so that the tab 46 is removed when verifying the emergence of the ejector blade 48. To facilitate the exit of the ejected specimen. The output tray 52 corresponding to the next downstream door or exit tray 28 is subsequently extended on a deflector plate 54 on a downward ramp. To facilitate the slipping of the magazines 55 ejected on the exit trays 52, these trays 52 have in their bed pressed rolling balls 53.

The invention provides for ease of access to the endless belt 26 through the interior of the frame of the machine 25, for assembly and maintenance work. For that purpose, said ninth means are provided, consisting in that the support legs 29 of the machine 25 which are adjustable in height, on their highest side, have a collapsible section 30 which passes through said access.

Identifying readings of the copy or object that have been described as having optoelectronic means associated with the identification of the printed image, can be complemented and / or replaced by code reading means associated with each copy or object (bar codes, magnetic signals , photosensitive prints, electromagnetic signals, etc).

Referring now to Figures 15 to 20, we can see the preferred embodiment for an automatic feeder that can be used in the machine according to the device for processing the return of invented items, and which can also be used for another different machine and processing, since it is an independent element that can be easily included or not in an installation, as we will see below. The automatic feeder is generally referenced with the number 56.

This automatic feeder 56 has a hopper 57 defined by a slotted bed 58, a fixed wall 59 and a movable wall 60. The specimens will be deposited with the loins resting on the grooved bed 58 and referenced on the fixed wall 59. Since the grooved bed has an inclination of 352, the entire stack of specimens will be supported on the rear mobile wall 60.

The specimens will be removed from the front part of hopper 57, by means of a vacuum suction cup 61. This cup will be located opposite the angle formed by the slotted bed 58 with the fixed wall 57.

Being close to the fixed wall ensures that one hundred percent of the surface of the suction cup is positioned on top of the specimen to be extracted, regardless of its size, avoiding extracting two * at a time. Being close to the edge of the grooved bed is able to apprehend the specimen for its most consistent part, that is, near its back.

The suction cup has a reciprocating movement, so that, when it is in the forward position, it sucks the specimen, during the recoil it extracts it, and when it reaches its most delayed position, the aspiration ceases and drops it by gravity. This suction cup 61 carries a device that detects if the specimen has not been apprehended, and then starts retrying before it reaches the end of its backward travel. All the reciprocating movement is controlled by an electronic synchronism device to match the fall of the specimen on the collecting tape 62, at the appropriate time and place. While the extraction device is operating, the movable wall 60 is advancing the appropriate distance to ensure that the specimen to be extracted is in the optimal position to be extracted by the suction cup 61. When the last specimen has been dosed, it is automatically wall goes back to the starting position, so that Hopper 57 is reloaded.

The spine separating device, generally referenced with the number 63 and which is clearly seen in Figure 17, is formed by the striated profile 64, a lateral air flow device 65, and spacer strips 66.

The striated profile 64 is placed just at the edge of the grooved bed. Its special section with two radii of curvature manage to retain the spines of the specimens (especially those that are curved forward), until the suction cup overcomes that resistance to extract them.

The air ejector device 65 sends pressurized air from the bottom of the fixed wall 59 and next to the profiled profile 64, preventing the possible approach of the spine of the specimen that follows the one to be expelled.

The separating strips 66 have their fixed rear end by means of a fastener to the grooved bed 58 and the other end raised to form an angle of 90-5 with the rest of the strap. They allow the passage of a copy when the entire stack is pushed by the movable wall 60 and prevent the first two copies from joining, when the suction cup pushes the first of them to apprehend it. The automatic feeder 56 includes a device for extracting the specimen, generally referenced with the number 67, formed by the following elements:

- vacuum suction cup 61. This element is what makes the approach, contact, suction, extraction and release of the specimen. It is formed by - a housing 68 that encloses the tube 69 (see figure 16), and the outer grid 70 that produces the suction of the specimen when it comes into contact with it. The particular concave shape of the grid 70 It produces a zone of homogeneous and very wide depression around the center of the grid (which is where it comes in contact with the specimen) and even the tongue 71 that borders the suction cup. Thanks to this particular shape of the grid 70, optimum suction is achieved for articles of these characteristics (copies with or without gadget).

Solidarity to the suction cup 61 and at the bottom, there are two nails 72 (see figure 15) advanced with respect to the plane of the grid 70, whose effect is to push the back of the specimen to be extracted against the strips

66, this effect being particularly important in cases where the loins are curved forward.

Making special reference to the figure now

16, in it we can see how the mechanisms for the reciprocating movement of the suction cup 61 are shown schematically. It is achieved through a pneumatic cylinder 73 whose rod transmits its movement to a sliding tube 74, through the crank 75 whose point of rotation is at its lower end 76. The sliding tube 74 itself acts as a vacuum switch of the duct 69, thanks to a mechanism 77 provided with a pressure compensation chamber so that the sliding tube 74 does not suffer dominant forces that increase its friction on the sliding guides. This can be seen schematically in Figure 16.

- detection of apprehended specimen. When the sliding tube 74 recedes, the suction cup 61 approaches the specimen and at a certain point in its path it switches the suction of the duct 69 towards the grid. Simultaneously, the suction cup 61 advances until the sensor 78 (see figure 15) is activated by the effect of the suction cup action on the specimen. At this time the sliding tube 74 reverses its movement as the cylinder rod 73 advances. At a certain point of the advance travel, the grid 70 loses the suction effect and the specimen falls due to the effect of gravity.

- retry maneuver. When the suction cup 61 has seized the specimen and is removed with it sucked, the sensor 78 must remain activated. If this sensor is deactivated at the start of the recoil, it means that the specimen has not been taken, which immediately and automatically retries the maneuver, without waiting for the suction cup to complete the recoil cycle.

- remaining anti-suction stops. It is an inverted "U" shaped structure, the plane of which is slightly more advanced than the plane of the suction grid when it is fully retracted. Therefore, these stops take off the copy of the suction cup when there is remaining suction, despite having been removed the vacuum, as can be deduced when observing Figure 15.

- synchronization elements in the extraction. They are defined by electronic control elements that, in addition to coordinating and governing the entire process, direct the action of the pneumatic cylinder through its solenoid valve. Therefore, the response of the suction cup to the movement of the cylinder is controlled and allows synchronization with events outside the feeder, which will allow you to dose each specimen at the appropriate time and place. As the suction cup extracts specimens from the front of the hopper, it is necessary to push the entire battery that awaits. in the hopper to ensure that there is always a specimen on the edge, ready to be ejected. The device for moving the entire stack of copies consists of different elements that are detailed below:

- mobile wall. The entire stack of copies rests on the movable wall 60, which moves by sliding on the grooves of the grooved plate 58 by the action of the cylinder 80, as we can see in Figure 15. The movement of the cylinder 80 responds in turn to the deactivation of another sensor 79 placed on the grooved plate and, in part, inserted into the grooved profile 64. When the sensor is deactivated it indicates that the specimen has already been ejected and the cylinder 80 must act until another copy is prepared; This occurs when sensor 79 is activated again.

- compensating elements of the deformation of the pile. As we have seen previously and in order to prevent the spines of the specimens of the stack from arching forward, two elements are available on the mobile plate 60 itself. On the one hand, a pusher plate 81 (see figure 15) which It is the one that is really in contact with the battery. The special shape of this plate corrects the effect of deformation. To further assist in this correction, it has been provided that a part of said plate is movable by the action of a pneumatic cylinder. This pneumatic cylinder moves forward when there is more than one retry maneuver. - wall recoil, mobile. A sensor attached to the pusher plate 81 indicates when the last specimen has been removed from the stack. At this time the cylinder 80 pushes the plate back to its initial position. This initial position has been previously programmed by means of the switch 82 so that the cylinder goes back completely, or only halfway, depending on the size of the batteries that are waiting to be charged, thereby optimizing the times dead.

With special reference now to figures 18 and 19, we can see in them the mechanism for collecting the ejected specimen. Since ultimately the stock of the ejected specimen is made by gravity, and given the heterogeneous nature of the specimens that occupy us, whose sizes, consistencies, thicknesses and positions of their centers of gravity are different, it is not If the contact between the spine of the specimen and the sliding profile of the return control machine is expected to occur simultaneously at all its contact points. To achieve a good contact between the specimen and the profile, the mechanism for collecting the ejected specimen is used, formed in this example of preferred embodiment by the following elements:

- loin conditioner. Rocker plate

83 prevents specimens whose spines are of an important thickness, fit into the displacement profile

84 without being able to be transported by sliding.

On the other hand, the nozzle 85 projects pressurized air so that the loins combined upwards adjust to the tapestry 86 of the transport of the return control machine and contact the displacement profile 84 when sliding down.

- shock absorber. The travel profile 84 is interrupted in the area of the collection mechanism. This new section of profile, reference with 87 is not directly connected to the return control machine, as in the case of profile 84, but it does so through a simple damping mechanism formed by two pneumatic cylinders 88 whose stems they join the profile 87 through an elastic transmission 89. In Figure 20 we can see drawn in perspective, the arrangement of two feeders for the application to the dosing of copies to the machine controlling the return of invented publications. One of these automatic feeders will be the mirror image of the other and allows the operator to load, placed in the middle of them to access the loading hoppers on his right and left.

The operation is as follows: the operator loads a package into one of the automatic feeders 56 and presses the "ready" button 90 (see also the figure 15). The control system receives the package code. The feeder starts dosing. The operator loads the other automatic feeder 56 with the following package and presses the "ready" button 90. The control system receives the code from that package. When the last copy of the first feeder is dosed, the second one is automatically started. The operator loads the initial feeder 56, and so the cycle is repeated.
