Description

The invention relates to the technical sectors of devices paper towel dispensers, toilet paper, paper towels and the like made in all paper-based material, paper wadding.

The invention also relates to the technical sectors relating to these devices as part of automatic operation or semi-automatic with dispensing of the drawn strip of paper in a flat, unfolded form, or in a folded form.

It is known in this kind of material and apparatus dispenser of provide for the use of a reserve roll likely to be place in the machine before finishing the service roll. It is recalled that these rolls are in the form of a reel of material wound with a support mandrel, of cardboard material for example, and arranged in a horizontal plane in the apparatus.

Various studies have been carried out in particular by the applicant for set up a device for loading a reserve roll with means for controlling the diameter of the material reel in reeling course.

There is particularly a roller loading device reserve for a dispenser of this kind described in the French patent n ° 95/12107.

We briefly recall the main arrangements of the device distributor.

The device for dispensing wiping material, toilet paper, paper towels, paper towels and the like, includes a housing on which is hinged a cover, said casing being arranged with two support flanges perpendicular to the bottom face of the casing, a drum being arranged transversely in the lower part of the casing, between the support flanges, including a cutting device integrated, the rotation of the drum being obtained by the effect of user pulling a strip of paper, a pressing element (8) being attached and positioned above the drum and maintained between the flanges of the casing, the lower part of the latter presenting a slot allowing the passage of the paper strip, the roll of material being held between arranged upper flanges, a receptacle being provided in the bottom part at the rear of the device.

In this request, the loading device has the function of check the end of distribution of the initial service roller (R1) previously positioned in the receptacle in order to set up a new roll called "reserve" (R2) positioned between the flanges, the loading device includes first means positioned and fixed inside the cover in one position substantially opposite the place of passage and introduction of the strip of material on the drum for cutting, and second complementary means arranged from the housing the device, said second means being armed by closing the cover and being capable of controlling the end of the course of the first roller (R1) and to control the actuation of said first means disposed on the cover after exhaustion of the first roll to load the strip of paper from the roll called "reserve" (R2).

Various means are exposed in this patent to allow the operation of the claimed device.

In this patent it is provided that when the material reel comes to escape from its gripping support means, after putting in control of the reserve roller loading device, the end paper strip of the latter is hanging down in front of the drum and the pressing element while waiting for its introduction within the interval between the drum and said pressure element. In practice, it is when the cover of the device that a plate-type means presents the free end of the paper strip coming from the roll of reserve between the drum and the pressing element to ensure gradually taking charge of it, then the course of the spool of the reserve roll.

In this design which is perfectly reliable, in terms of operating mechanisms, this requires the use of pushing means, of the tab type, associated with the cover of closing the device. This pusher means acts on the free end of the paper strip by controlling a linkage and slide associated with a testing device capable of detect the expiration of the roll reel in service after the distribution of its last unit of paper. A pushing means is likely to allow and facilitate the introduction of paper between the drum and pressing element. This arrangement is satisfactory in principle but it is subject to a good position by the operator of the free end of the strip of the reserve roll arranged in the upper part of the appliance. Indeed, if the roll of reserve is not sufficiently unwound on the front of the device facing the drum and the pressing element when insert the free end of the paper strip between the drum and the pressing element, it may happen that the means of thrust is not enough or not in contact with the paper so that it has absolutely no pushing effect and the loading operation is not ensured. That is particularly troublesome since the device does not work not. The operator, believing to have set up the device normally, if it does not perform a test run as a precaution, may leave this device to the public pending their next visit to control.

It has also been provided in patent No. 92/12107 for the use a pinch plate of the paper strip. Its implementation nevertheless remains very limited and impractical.

Also, one of the aims sought, according to the invention, was to improve and perfect the reserve roller loading device by avoiding the reported inconvenience so that the operator who is responsible for the care and maintenance of this device is brought systematically to position very precisely the strip of paper from the reserve roll for later viewing positioning to ensure continuous operation of the device.

Another object sought after according to the invention was to help the operator to determine the degree of unwinding of the service roll and define movement.

These and other goals will emerge well from the rest of the description.

According to a first characteristic of the invention, the device for load includes a pinch and hold-down device the free end of the strip of the reserve roll positioned from a transverse plate established in front of the drum on all or part of its length, the clamping device being urged by the closing of the appliance cover or by a mechanism arranged from the housing of the device, the clamping device being located substantially opposite of the interval formed between the drum and the pressing element to allow the introduction of the paper strip from the roll of Reserve.

According to another characteristic, the clamping device comprises a screed shape arranged on the transverse plate, side inside of the device, receiving a free rotation roller, and underlying this pebble is fitted a tab with a window allowing the passage and articulation of a tilting pawl shaped as an "S", the ratchet having a first end passing through the window of the leg and a second end projecting outwardly from the plate to be acted upon by closing the cover in order to grasp and pinch the end of the paper strip.

These characteristics and others will emerge well from the following from the description.

In order to make the object of the invention more concrete, it is described now in a nonlimiting manner illustrated in the figures of drawings.

This dispensing device, referenced as a whole by (1), is arranged with a casing (2) made of plastic material or otherwise on which is hinged a cover (3) made of similar material. The housing receives two lateral outer wings (2a - 2b), as well as two support flanges (4 - 5) added perpendicular to the bottom face of the casing and held by snap-fastening or the like at the base thereof. AT the inside of the housing is arranged transversely between the flanges of the casing, a drum (6) including an integrated cutting device (7) and operating, for example, but not limited to under the conditions of French Patent No. 2,332,215.

The drum (6) can be arranged in any suitable manner. The the drum is rotated by the pulling effect of a strip of paper by the user using an eccentric means (8) associated with a return and launch spring (9) fixed to one of the flanges (4) of the housing. A pressing element (10) is attached and positioned above and resting on the drum transversely and in the same axial plane, being maintained between the notches (4a - 5a) established for this purpose in the flanges (4 - 5) of the housing. In his part low, the housing has a transverse slot (11) allowing the passage and distribution to the outside of the paper strip intended to be entered by the operator. A follower roller (12) is positioned in the lower part of the device.

The roll (R1) of material is held by arms (12) retractable in accordance with the flanges (4 - 5) and they are arranged with end caps (13) capable of allowing introduction to quick assembly of the roller sleeve in question.

The loading device can be used when the use roller (R1) is at the end of service. Under these conditions, the roller at the end of service must be moved by an operator and be positioned in the bottom part and at the rear of the device forming receptacle (14). Another so-called reserve roller (R2) is put in place.

The purpose of the loading device is to control the end of dispensing of the initial service roller (R1) at the end of use, in order to loading phase the new roller (R2).

This loading device therefore includes first means which are likely to secure and maintain the free end hanging from the strip coming from the new roller (R2) reserve, as well as second complementary means arranged to from the device housing. These last means are likely to detect the end of the unwinding of the first roller (R1) and control the actuation of the first means ensuring maintenance and retaining the tape end of the reserve roll (R2).

According to the present invention, the device cover is smooth internally and does not include any particular reported form.

The device includes a clamping and retaining device the free end (B1) of the strip of the reserve roll or the first serving roller used and is positioned from a plate transverse (15) established in front of the drum (6) over all or part of its length and therefore of the device. This transverse plate (15) is advantageously fixed with quick disassembly and by snap-fastening on the side walls and flanges (4 - 5) of the device capable of holding the drum. This transverse plate is articulated at its base by fingers (15a) penetrating into openings (4a - 5a) formed on the abovementioned flanges (4 - 5). The upper part (15b) of the plate transverse is arranged to receive the clamping device and retainer, referenced as a whole by (16), from the free end (B1) of the reserve roll paper tape. This device (16) is arranged in a plane such that it is located substantially opposite the gap formed between the drum (6) and the pressing element (10) to later allow the introduction of the paper strip from the reserve roll between them. This device includes a yoke (16a) arranged on the transverse plate (15), inside of the device, receiving, freely rotating, a roller (17). Underlying this pebble is provided a tab (18) having a window (18a) or cutout interior allowing passage and articulation of a ratchet (19). This pawl is articulated on an axis (20) established and positioned in the part lower of the yoke. This ratchet is profiled in a configuration substantially elongated "S" with a first end (19a) capable of passing through the window (18a) established on the tab (18) mentioned above, and the other end (19b) liable to overflow externally from the transverse plate (15) through a window (15c) complementary formed thereon. Advantageously, this tilting pawl (19) is free and is not used by any means of reminder. Its inner end (19a) is advantageously arranged with a gripping area (19c) such as a rubber pad or equivalent. In the non-solicitation phase, the tilting pawl (19) is held in the lowered position. Its inner end (19a) comes in abutment against the inner edge (18a) of the receiving tab (18) while that its end (19b) projecting outwardly is located substantially in a plane projecting perpendicular to the plane of the transverse plate (15). This pawl (19) is armed during the closing the cover (3) of the appliance. Indeed, the inside front face (3a) of the cover is likely to come to bear and push against the protruding part (19b) of the pawl thus ensuring its pivoting and the contact of its part (19a) against the roller. We therefore understand that, when loading the reserve roll (R2), the operator must present the free end (B1) of the reserve roll in a position as it appears next to the clamping device (16) as well described. The strip (B1) of paper is thus held firmly between the tilting pawl (19) and the roller (17) during the entire phase of closing of the cover (3) on the device. This cover acts under pressure continues on the device (16) as long as the latter and the plate transverse (15) corresponding and associated remains in a position spacing relative to the drum (6) and the pressing element (10). We thus understands that the spool of reserve material remains in this position as long as the clamping device (16) is not activated, following a particular event corresponding either to the opening of the cover, either by the intervention of a mechanism intermediate causing the release of the tilting pawl (19).

Considering that the service roller (R1) has been moved from its initial high position between the tips to be positioned in a receptacle (14) established in the bottom of the apparatus, it is then observed that you can insert and position the reserve roller (R2) in the upper part of the appliance. The service roller (R1) continues to be unwound, the strip of paper going around the back, in the way described in patent n ° 95/12107, the drum (6) and the pressing element (10).

In French patent No. 95/12107 of the applicant, a special mechanism associated with a test member (20) intended to identify the end of the service roller (R1) located in the receptacle (14). We now describe the different components of the above mechanism which are likely to intervene directly on the clamping device (16) and retaining the paper strip (B1) from the roll of reserve (R2) when the cover is closed, or from the service roller (R1) at the start of the cycle.

The control and release mechanism of the device (16) pinching is carried out as follows. The tester (20) is arranged to from a hinged profiled support piece (21), forming a lever, arranged parallel along the flange (4) of the device. This lever (21) can be moved backwards under the pushing effect produced by the profile lower oblique (3a) of the cover (3). Thus, in its front part, the hook-shaped lever (21a) and it bears against said lower profile (3a) of the cover. Raising the cover causes the raising of the lever (21) and its rearward tilting causing the others mechanisms. Said lever (21) is subject to a return means (22) of the spring type with one end (22a) fixed to the base (2a) of the housing and the other end (22b) at the rear of the support piece (21). It is provided the positioning of another spring (23), one end (23a) of which is hung on the drum launch eccentric (8) and the other end (23b) is fixed on a fixed point (21b) established in the part rear of the lever (21).

The rear part of the lever is arranged to receive a plate horizontal (24) formed integrally with the lever (21) and receiving an axis (25) projecting externally to engage in a light (4c) curvilinear established in the flange (4) facing the device. This axis (25) is capable of allowing the fixing of a slide (26) arranged in a longitudinal plane along the flange (4) of the device. This slide comprises, in its rear part, a plate (26a) having an oblong opening (26b) engaging on the axis (25) above, while it extends over a great length towards the front of the apparatus having a hook shape (26c) which adjusts and cooperating on a finger (27) established on the transverse plate (15) support of the clamping device (16).

A return spring (28) is disposed with one end (28a) on a point (29) of projection formed on the transverse plate (15) and the other end (28a) anchored to a fixed point (30) of the wall of the device.

The tester (20) is arranged articulated with respect to the flange (4) of the device. This includes, for example, two flat strips (4th - 4f) parallel and superimposed having openings (4e1 - 4f1) of positioning of the centering finger (20a) and of the articulation formed on the testing member (20). Between the flat strips (4e - 4f) is provided a window (4g) allowing passage and articulation of the free arm (20b) of the testing member (20). The latter comprises in axial overflow a upper finger (20c) allowing the fixing of an elastic means (38) of reminder whose other end (38a) is anchored to a fixed point (4e2) of the upper flat strip (4th). The tester (20) includes a lower finger (20d) which is guided and which penetrates into a tongue (29) articulated through an oblong lumen (29a). This finger (20d) comes in stop against the horizontal plate established in the rear part of the lever (20) driving the articulation thereof. The tongue (29) is horizontally guided through two superimposed plates (30a - 30b) fixedly positioned on the side of the fixed flange (4) of the casing. This tongue (29) is very long and is susceptible, by its part before, to constitute an abutment plane (29a) of a part in the form of hook (15e) formed perpendicularly on the transverse plate (15) support of the clamping device (16). This hook shape (15th) is established in the extension of the wing (15f) of the transverse plate (15) on which are fixed and articulated the slide (26) and the means of reminder of the transverse plate. So we define a limitation of tilting back of the transverse plate (15).

It is now appropriate, with reference to the various figures of drawings, to explain the operating mode of the device and the loading device in particular, recalling that the elements Roller structure of the cutting device may vary.

In the initial loading phase of the device, the operator positions a first service roller (R1) and presents the end of the paper strip (B1) opposite the pinching device (16) formed on the transverse plate (15).

When closing the cover (3), the inclined lower part (3a) of this one, adjacent to the opening area, comes into progressive support, part against the projecting end (19b) of the rocking lever (19) of the pinch device (16) causing the paper strip to be pinched (B1), and secondly a support against the lever (21) disposed in the casing (2). The lever (21) is thus raised then pushed backwards causing the angular pivoting of the tester (20) until the latter comes substantially into the cutout (31a) formed on the transverse plate (31) rear of the casing behind the drum (6). Simultaneously, the rearward tilting of the lever (21) causes the rearward drive of the slide (26) and the folding of the transverse support plate (15) of the clamping device (16) and this against the various return springs. It also causes the drive and pivoting of the tester (20) until its arm (20b) comes substantially opposite the cutout (31a) or slot established on the back plate (30) behind the drum. The tongue (29) associated with the test member (20) maintains the transverse plate (15) by the effect of the hook (15th). Having no service roller (R1) located in the bottom part of the receptacle, the testing member (20) is not subject to no counter-support and it can freely, by the effect of movement of the lever, enter the aforementioned window (31a) at causing by a hinge effect the horizontal tongue (29) in a backward movement until releasing the forming part hook (15th) associated with the transverse plate (15) supporting the pinch device (16). This hook part (15th) is then released and, thanks to the relaxing effect of its return spring, the plate transverse (15) support of the clamping device tips backwards. By this effect, the tilting lever (19) is released from the support of the cover (3) and by gravity it returns to its initial position. So it releases the tape from paper (B1) from the roll. By the effect of displacement towards the rear of the transverse plate (15) associated with the clamping device (16), introduce the paper strip (B1) between the drum (6) and the pressing element (10).

The device then operates normally under the traction effects of paper by the user.

When the maintenance officer visits the device to check the condition of exhaustion of the material reel (R1), it can then move the coil in service (R1) and position it in the bottom of the receptacle (14). he also positions a roller in the upper part of the device reserve (R2) and it proceeds in the manner described above for pinch its free end in the device (16) designed for this purpose.

After closing the cover (3), the reserve roller (R2) has its free end (B1) of band held by the device (16), while that the tester (20) is positioned, after movement of the lever (21), against the paper strip (B1) coming from the service roller (R1) still being distributed. In this case, the pivoting of the organ tester (20) is not sufficient to escape the hook part (15e) of the clamping device support plate, outside the support plane of the tongue (29). The device then allows the continuous distribution of service roller (R1) until it is exhausted to release final the testing device (20) and its action on the slide (26) by the displacement of the tongue (29) with the tilting of the plate transverse (15).

Furthermore, and according to an important provision of the invention, the organ tester is likely to provide an additional function for detach the paper strip from the service roller during the finishing phase. Due to its length, the test member comes to bear on the strip of roll paper to finish. When rotating the drum, for the last strip of paper to be dispensed, this is glued to the support sleeve the coil, according to a known technique to allow winding. Of by the lightness of the sleeve, the drum, turning, drives the paper, and therefore the sleeve associated with it. The latter comes into abutment against the rear face of the tester body which provides a counter-support function by causing the paper to take off relative to the sleeve and therefore its ejection into the bottom of the receptacle.

The advantages of this arrangement result in the better behavior from the end of the waiting paper strip. There is an obligation to the operator to position it correctly, otherwise the device is no longer able to function. Better reliability is therefore obtained under the conditions of use of the device.

In addition, there is provision in the upper part of the apparatus, a member (32) capable of controlling the unwinding of the upper roller. This member (32) is established in the form of a plate vertical whose ends (32a - 32b) have fingers (32c - 32d) protruding into fixed parts (4g - 4h) of the flange (4) of the device. The plate (32) thus has on one side a tongue (32e) overflowing inner bearing against the edge (B2) of the coil (R1 - R2) and, on the other side an overhanging tab (32f) having advantageously a colored display area (32g). This plate (32) is thus articulated so that when the diameter of the coil is reduced so as to escape the grip of the plate (32), the latter pivots against an elastic return means (33). The visual element is then moved slightly to be opposite an identification and identification window (3b) formed on the cover (3). This means that the operator can charge the device again. The elastic means (33) formed on the plate (22) is established for example in the form of a tongue whose free end (33a) is supported against a fixed plate (4g) of the member (32) and the other end (33b) on this one.

In addition, it is specified that the bottom of the casing of the device has a hinged flap (2b) allowing the evacuation of the sleeve from service roll finished. The joint is obtained by a simple shrinking of matter. It is the lifting of the cover that causes closing the shutter.
