Definitions
- the present invention relates to a machine for automatically inserting photographs, postcards, membership cards and other sheet-like objects into respective sleeves.
- Machines of this type are commonly used in photographic laboratories, photography shops and workshops, as well as by collectors, in order to insert photos, magnetic cards, postcards, picture cards and similar objects.
- a further aspect of the invention relates to a sleeve with a single fold intended to be used with this machine, as well as the method for manufacture thereof.
- European patent application EP-A-832,759 discloses a machine of the abovementioned type which comprises a store for containing the photographs supplied directly from a machine for developing negatives, and a mechanism for removing the photos one at a time and combining them in mutually facing positions. Then, the pairs of photos are inserted into a sleeve which has two pockets by means of a special thructer.
- the machine also comprises a device for feeding the sleeves which are provided in the form of a continuous strip wound up so as to form a roll.
- the machine of the abovementioned type has certain known drawbacks which limit its versatility and operating speed.
- the use of the thruster to insert the photos inside the sleeves reduces the sleeve-filling speed of the machine since the return stroke of this component, following its outward stroke during the insertion of pairs of photos, constitutes idle time which cannot be eliminated.
- the sleeve-filling mechanism operates in such a way that the first sleeve in the strip is not used, but must be cut and separated since empty.
- a further disadvantage consists in the fact that the form of the sleeves which can be used in this machine does not allow easy extraction of the photos once the sleeves have been mounted on the fastening rings inside a folder, since the sleeve opening is situated on the side where the holes for the fastening rings are also formed.
- a sleeve-filling machine which comprises a system for feeding the photos in the form of a conveyor belt on which the photos are arranged; the photos must initially undergo a separating operation in order to form two packs of photos, i.e. a first pack of photos in an odd sequence and a second pack of photos in an even sequence. The two packs are then arranged in two stores formed on the said conveyor belt.
- a suitable driving device removes one photo at a time from each pack and forms the pairs which are inserted into a middle store and then inserted into respective sleeves forming part of a continuous strip wound up in the form of a roll.
- a major disadvantage of this known machine consists in its considerable constructional complexity due to the presence of a conveyor belt and the rotating middle store. Moreover, the photo feeding system does not operate continuously, but in an alternating manner, resulting in idle time which reduces the efficiency of the machine as a whole.
- a "single-fold" sleeve is known, said sleeve being made from a film-like strip of transparent material folded so as to form two flaps of different height constituting the walls of the said sleeve after the strip has been cut at predefined distances.
- One of the edges of the sleeve which has an essentially rectangular shape, is formed by folding the strip onto itself. The two edges perpendicular to the first edge are welded and the fourth edge, which is parallel to the first edge, remains open so as to allow insertion of the photograph or the object to be protected.
- a strip consisting of a single piece of film projecting on the pocket side of the sleeve is formed.
- One or more holes which are used to bind several sleeves together inside folders or albums are formed in this strip.
- the sleeve of the abovementioned type is not devoid of certain known drawbacks, the first of which consists in its limited efficiency, due to the fact that it cannot be easily extracted once it has been attached inside a folder. In fact, the fastening holes are formed in the region of the open edge, which is therefore obstructed by the fastening rings after binding.
- Another drawback of the known sleeve consists in the structural weakness of the projecting strip in which the fastening holes are formed, said strip being formed in a portion where the film consists of a single layer. This is the cause of frequent breakages, even more so since, whenever a photograph is extracted or replaced, the sleeve must be removed from the fastening rings. Alternatively, the region around the holes must be reinforced, resulting in the need for costly and laborious operations.
- a main object of the present invention is that of overcoming the abovementioned drawbacks of the machines according to the present state of the art by providing a machine with a simple and reliable structure and low manufacturing cost.
- a particular object is that of providing a sleeve-filling machine which allows rapid and automated insertion of the photographs into suitably shaped sleeves using a process of the continuous type so as to reduce substantially the idle time.
- a further object is that of providing a sleeve-filling machine which is able to handle different formats of photographs, eliminating at the same time the risk of damaging and folding the photos due to the presence of thrusters.
- a further object of the present invention is to overcome the abovementioned drawbacks relating to sleeves of the known type by providing a sleeve for the automatic machine having a form which is simple, low-cost and easy to manufacture.
- a particular object is that of providing a sleeve which allows rapid insertion of the photographs by means of the automatic sleeve-filling machine according to the invention.
- Yet another object is that of providing a sleeve which has a high structural strength of the fastening points in order to ensure more secure fastening.
- a first aspect of the invention envisages a sleeve-filling machine which, in accordance with Claim 1 , comprises a support frame which supports a strip forming a succession of adjacent sleeves with one side open, feeding means for discontinuous feeding of said strip in a first direction substantially parallel to the open side of the sleeves, a store for storing the articles to be inserted into sleeves, a transfer station for removing the articles and for inserting them into respective sleeves in a second direction substantially perpendicular to the first direction, characterized in that the transfer station comprises a roller-type driving device interacting tangentially with at least one flat surface of the articles to inserted into sleeves.
- the sleeve-filling machine has a simple and reliable structure, operates continuously, drastically reducing the typical idle time of the machines according to the prior art and allows the articles to be inserted safely, without the risk of damaging or folding them during insertion.
- a second aspect of the invention envisages a single-fold sleeve which, in accordance with Claim 1 9, comprises an element which has an essentially rectangular shape with a pair of transverse edges and a pair of longitudinal edges, said element being formed by a strip of sheet-like flexible material which is folded onto itself in its middle part so as to define a pair of flat mutually facing walls joined together along the transverse folding edge, said walls being joined along the two longitudinal edges by means of a pair of continuous seams, the second transverse edge being open so as to define an opening for introducing the photos, characterized in that it envisages a third longitudinal seam which joins together said flat facing walls in a substantially parallel and intermediate position with respect to the first two seams, so as to divide the sleeve into two separate pockets.
- the sleeve has two pockets, the larger one of which is suitable for receiving photographs and other similar objects, while the narrower pocket has a reinforced zone suitable for being provided with binding holes.

- the friction means may consist of a layer of resiliently yielding material deposited uniformly on the outer surface of each roller.
- suitable guiding means may be provided in order to ensure efficient feeding of the articles F in the feeding direction V2. These guiding means may consist, for example, of two adjustable side brackets 1 8, 19 which are positioned transversely with respect to the movable rollers 12, 14 and the distance of which may be adjusted according to the width of the articles F.
- means for separating the flaps L', L" of the open edges 27 of the said sleeves may be provided, said means consisting, for example, of two blades 20, 21 .
- the machine will be controlled by an electronic control unit 22 to which there is connected a sensor 23 located on the rule 7 for detecting the bar code M of each sleeve and the motors 9, 1 5 for performing co-ordinated operation thereof so as to insert one object at a time fully into a respective sleeve B when the latter is positioned along the path of the transfer device 10.
- the control unit 22 may be of the processor type and may be suitably programmed so as to wind up the strip N in a direction V3 opposite to the direction V1 so as to allow the first sleeve in the next sleeve-filling cycle to be used again.
- the roll R may be acted on by a suitable tensioning device consisting of a compensator or jockey roll, which is within the technical competence of any person skilled in the art and not shown in the drawings.
- the second embodiment illustrated in Fig. 7 differs from the preceding embodiment in that it envisages, downstream of the first roller 1 1 , a calibrated passage 100 having an inlet opening 101 with dimensions slightly greater than the thickness of the article to be inserted into sleeves and an outlet opening 102 formed in the vicinity of a pair of opposing rollers 14, 14' at the distal end which have a diameter smaller than that of the first roller 1 1 and are located in the vicinity of the open edge 27 of the sleeves B.
- the sleeves B will be guided towards the inlet opening 101 of the calibrated passage 100 by an inclined surface 103.
- they will be conveyed towards the opening 101 by a substantially vertical guide element 104 against which the photograph F comes into abutment, pushed by the first roller 1 1 .
- the abovementioned pair of opposing rollers 14, 1 4' at the distal end may comprise an idle upper roller 14' resiliently supported by a flat spring 105 fixed to the support frame 2 by means of screws 106.
- said figures show a sleeve B which can be used with the machine 1 described below, said sleeve B consisting of an element or pocket T which has a substantially rectangular shape in plan view, with a length G and width Q, having two longitudinal edges 24, 25 and two transverse edges 26, 27.
- the element or pocket T is formed by a pair of flat superimposed sheets or walls 28, 29 made of a base material consisting of a film of flexible material, which is preferably synthetic and transparent, for example PLP which can be hot-welded and has a good transparency and tear strength.
- a base material consisting of a film of flexible material, which is preferably synthetic and transparent, for example PLP which can be hot-welded and has a good transparency and tear strength.
- the two walls 28, 29 are joined together by means of welding, bonding or other equivalent means, forming the two continuous seams 30, 31 .
- the transverse edge 26, which forms the bottom of the sleeve, is formed by the edge obtained by folding the strip of base material.
- the other transverse edge 27, opposite to the folding edge 26, is left open so as to define an opening for insertion of the articles F.
- the sleeve B is provided with a third longitudinal seam 32, which is also obtained by means of welding, bonding or other equivalent techniques, being arranged substantially parallel to the two edges 24, 25 and located in a position such that the distances from the two longitudinal edges 25, 26 are different.
- a third longitudinal seam 32 which is also obtained by means of welding, bonding or other equivalent techniques, being arranged substantially parallel to the two edges 24, 25 and located in a position such that the distances from the two longitudinal edges 25, 26 are different.
- two secondary pockets 33, 34 of different widths, respectively Z, W are obtained.
- the wider secondary pocket 34 is intended to contain the photographs or objects to be protected F and its dimensions are therefore determined according to the dimensions of these objects, while the narrower pocket 33 may contain information or identification data which is applied or printed thereon.
- the secondary pocket 33 which has a smaller width Z defines a strip which is sufficiently wide to allow the formation of one or more holes 35 which are substantially aligned with each other hand and which are used for insertion of fastening rings which allow binding of the sleeves so as to form albums, catalogues or books.
- the holes 35 will have a greater tractional resistance than in the case of the known sleeves where the holes are formed in the zones consisting of a single layer of film.
- the seams 30, 31 and 32 are interrupted.
- the end portions of the walls 28, 29 remain separate, forming two flaps L', L" which may be separated. This makes it easier to insert automatically the photos using the machine described above for this purpose.
- the sleeve B may be provided with a identification symbol or marking consisting of an area M printed in the vicinity of one of the edges of the sleeve. This area has the function of allowing optical recognition for the machine which produces the said sleeve.
- the strip 36 is initially unwound in a feeding direction X and folded along its centre line 38, the two flaps 28, 29 being brought opposite and into contact with each other. In this way a folded section 39 with a dual layer of film is formed.
- Seams 30, 31 , 32 which are welded or bonded and have a length equal to the width of the strip or a length less than and up to a distance H from the open edge 27 so as to allow the walls 28, 29 to form two open flaps L' and L", are formed at predetermined distances along the strip. In this way a succession of sleeves 33, 34 are formed.
- the seams 31 , 32 will be at a distance W which is greater than that N between the seams 30, 32 so that the secondary pocket 34 will have dimensions greater than those of the secondary pocket 33.
- the size of the larger pocket 34 is chosen according to the dimensions of the object F to be inserted into the finished sleeve.
- the size of the narrower pocket 33 is sufficient to house a plurality of holes 35 which will be formed at a later stage.
- the strip will then be wound up onto a roll or a reel R intended for sale or to be used in an automatic sleeve-filling machine of the type described above.
- the finished roll R may be directly introduced into an automatic sleeve-filling machine for for photos and other similar objects, located downstream of the machine for manufacturing the sleeves.
- devices for winding up the series of sleeves in a suitable manner for example in concertina fashion for delivery to the customer, may also be provided.
