Description

APPARATUS FOR DISPENSING WIPING MATERIAL COMPRISING A MARKING AREA FOR ALL SANITARY, HYGIENE APPLICATIONS. AND INDUSTRIAL.

The invention relates to the technical sector of devices for dispensing wiping material, automatic cutting or not, in the folded state or wound coil, pre-cut or not. The applicant has developed for this type of dispensing devices wiper material many innovations in relation, for example, with the operation of the devices, the control of the tensioning of the strip of material, the selection of the format, the loading of the apparatus, the implementation of a reserve roll intended to replace the roll of exhausted material. The applicant thus has expertise for more than 40 years in this technology and therefore has in-depth knowledge for the exploitation of all or part of its inventions and also competition manufacturing third parties.

To his knowledge and until now strips of wiping materials to distribute all have a smooth appearance on their surface, and are wound or folded, pre-cut or not to be distributed by the appropriate device.

One of the problems posed to the applicant at the origin of the invention lies in the fact that the rolled or folded wiping material may have various manufacturing sources for the same dispensing apparatus.

This situation is detrimental to device manufacturers who have to invest by creating in relation for some with the applicant, expensive research and development to improve their devices and make them the best possible to capture customers and retain them for distribution then consumables that is to say the wiping material packaged.

Many attempts have been made to try to make the supply of the wiping material indispensable with the original dispensing apparatus. The applicant has worked more particularly on the configuration of the bits for the case of wiping materials packaged in coils with specific arrangement of the apparatus. In addition to the fact that some users of spools of wiping materials recover the end pieces to position them on mandrels of coils of coiled materials of origin of different fabrications, the modifying investments of the apparatuses remain heavy and the shapes of the mechanisms complex. One of the solutions has for example consisted in making the tip unusable end of the roll by a deterioration of its end. The technical solution is reliable but the implementation complex.

It is therefore from all these files, that the applicant has oriented his research in a different direction with a new orientation directed at the wiping material itself. Until now the wiping material has a smooth configuration and regardless of its mode of distribution coil or in the folded state, and in both cases pre-cut or not.

The solution devised by the Applicant and the object of another patent application is to achieve on the strip of material throughout its length and especially a portion of its width at least one marking area constituting on the front and back of said band a succession of reliefs and recesses, in any configuration and cooperating with a mechanism disposed in the dispensing apparatus and ensuring that only the strip of material thus marked can be distributed by said apparatus. The implementation of this concept appears simple and requires the design of a very particular device that is the subject of the present patent application. Thus, the wiper material dispenser for sanitary and hygiene and industrial applications of the type comprising a casing and a hinged lid for the distribution of folded material in a reel characterized in that the strip of wiping material comprises on its entire length at least one marking zone having imprints of any configuration appearing on its two-sided faces and in that it comprises a mechanism having a pressure roller arranged with an identical complementary shape with an imprint in counter form so as to allow only and exclusively the passage of the web of material through entanglement of shape, and in that the rotation of the pressure roller generated by the passage of said web of material during the loading of the apparatus causes the deactivation of the pressure roller which takes a retracted position after loading the band and this by means cooperating with said mechanism e.

According to another characteristic, the apparatus distributing the casing allows the positioning of a module integrating all of the mechanism and means authorizing the arming of the pressure roller during the loading phase of the strip of wiping material during closure. the cover of the device.

According to another characteristic, the module comprises four main components a fixed frame a retractable flap a sliding guide and a top plate.

These and other characteristics will be apparent from the rest of the description.

FIG. 17 is a schematic view illustrating the positioning of a stack of folded wiping material stored in the dispensing apparatus.

In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings. The wiper material dispenser for sanitary purposes, hygiene or industrial use is referenced as a whole by (D). It is intended to distribute exclusively strips (1) of wiping material rolled up or folded, pre-cut or not and having at least one marking zone (1a) formed over the entire length of the strip and over all or part of its width. This marking zone has imprints of any configuration appearing on the front and back sides of the strip and can be made by embossing. The dispensing apparatus is thus equipped with a mechanism having a roller (2) arranged with an identical complementary shape with an imprint. in counter form so as to allow only and exclusively the passage of the web of material (1) arranged with the marking zone (la) through entanglement of the above-mentioned forms with rotation of the roller and exit of the web of material According to the invention, all forms other than those of the strip of material (1) and its marking area (la) and the pressure roller (2) do not allow any distribution of wiping material. Likewise, if the wiping material is in a smooth form, there can be no movement of the material strip but only a blockage of the apparatus, so that a repair and maintenance operation is necessary to remove purely and simply it and replace it with a strip of material suitable for distribution according to the invention. According to another embodiment of the invention, the dispenser apparatus is operable and cause the strip of material according to the invention essentially and preferably the loading of the apparatus to initiate dispensing. Once this loading of the band made, the pressure roller of the drive mechanism can be retracted that is to say put on hold of another loading operation of another packaging material coil or folded. In this situation, after loading initiation, the distribution of the web of material is carried out under normal normal conditions. The dispensing apparatus thus comprises a housing (3) of substantially parallelepipedal shape having in its lower part a horizontal base (3.1) capable of receiving or being in the extension of the upper part of a module (M) integrating the assembly of the mechanism according to the invention. Also, the module (M) has an upper plate (4) on which bears the band of wiping material implemented according to the invention is in a folded configuration or in a coil configuration. In both cases, the strip of wiping material is pre-cut or not. On its front part, the casing has a wall (5) articulated on an axis (5b) and shaped in its upper part with a curvilinear shape (5.a) facilitating the passage of the strip of drawn material. The housing receives a cover (6) hinged so that the strip of material runs between the inner face of the cover and the wall (5) facing.

The implementation of this module can be carried out thus in a dispenser machine with automatic cutting, the operation of the loading mechanism of the material strip according to the invention then being carried out in an automation in association with the mechanism of chopped off. It is then necessary to describe the module (M) and the loading mechanism of the strip of impression material and the constituent module with reference to the drawings, in particular FIGS. 5 to 14. The module comprises four main components, namely a frame fixed (7), a retractable flap (8), a sliding guide (9) and a top plate or top plate (4)., these components being in close relation to each other. Each component should be described and then their interaction clarified.

The flap (8) is more particularly illustrated in FIGS. 8, 11, 12, 13, 14. It comprises a front plate (8a) being fixed pivotally limited relative to the fixed frame by pivot points (8h) or hinges, or Similar.

The flap has in its central part a rectangular window (8b) for example to allow the passage and overflow of the pressure roller (2) during the loading of the strip of material. The flap has in its lower part a cutout (8c) showing a clearance for the passage of the strip of material (1) pulled. On either side of this cutout are two bars (8d), oblique protrusions formed integrally during molding for guiding and separation of the precut line of the strip of material used to guide it to be grasped by the operator. On the opposite inner face the flap (8) is arranged with two ramp (8 e) shaped cam obtained during molding and intended to cooperate with the sliding guide (9) arranged with complementary shapes. The flap has in its upper inner part a clevis shape (8f) intended to allow the articulation of a support (10) of the pressure roller (2). This shaped U-shaped stirrup support comprises two bent wings (10a-10b) which are arranged at their upper part to be articulated along axes (11) to the screed form established on the flap. Each of the wings (10a) (10b) of the support-stirrup of the pressure roller (2) is shaped to fulfill other functions, one common namely the articulation of a locking lever (12) which will be specified later , according to an axis of articulation (13) located in central intermediate position of the wings of said support or bending portion. The lower part of the first wing (10a) receives a disk (10c) mounted at the end of the axis (2b) of the pressure roller (2). This disk has an anchor point (10cl) of a first return means (14) whose other end (14a) is fixed in the upper part of the flap (8). This arrangement serves to launch the pressure roller (2) in rotation phase and are automatic return after passage of a neutral position in maximum extension of the return means (14). He acts in a way like an eccentric. The other wing (10b) of the stirrup support (10) has under the hinge axis of the lever (12) a fixed anchoring point (15a) of a second elastic return means (15), the other of which end (15b) is secured to the inner face of the flap (8). This second return means (15) is biased during the withdrawal phase of the pressure roller (2) after loading and remains in extended position until a new loading period. In addition, said second wing (1 Ob) of the stirrup support has a tab (10d) overflowing in a plane parallel to the plane of the flap (8) itself.

The locking lever (12) comprises two parts, first two arms (12a) hinged on an axis (17) formed in the bent portion of the wings (10) and (10b) of the stirrup support (10). Said arms (12a) come to a rear stop on the cam-shaped parts (2d) on the axis (2b) opposite the axis of the pressure roller (2). In the upper part, said arms (12a) are hinged a U-shaped hook (12b) shaped horseshoe. According to another arrangement the flap (8) has in its rear part a support plane (8g) and contact with the slide guide (9). The inward movement of the pressure roller (2) will cause by the tilting of the lever (12) the attraction towards the front of the horseshoe hook. It is therefore necessary to describe the slide guide (9). The slide guide (9) has an upper plate (9a) comprising a front wall (9b), and a rear wall (9d); the whole being monobloc. The slide guide (9) can be guided in position relative to a fixed frame (7). For this purpose, the slide guide (9) shown in FIG. 9 has a front face arranged in its upper part with vertical tongues (9e) which are capable of penetrating into oblong openings (7a) formed on the upper horizontal part (7b). fixed frame (7). The tongues (9e) are likely to overflow from the top of said frame according to the position of said slide (9). Furthermore, the front face (9b) has on its visible part two profiles (9f) in cam which are capable of cooperating according to the position of the pressure roller with the complementary shapes (8e) protruding from the inner wall of said flap. The horizontal inner portion (9c) of the front plate is connected by a third return spring (18) fixed to a fixed attachment tab (7e) fixed on the fixed cade (7) and serving to limit the upward movement. said sliding guide. According to another arrangement, the upper horizontal base (9a) of said slider is able to bear under the effect of expansion of the third elastic return means (18) on horizontal legs (7f) formed on the fixed frame (7). The rear wall (9g) of the slide guide (9) is able to bear on the upper edge (7g) of the fixed fastening tab (7e) limiting the displacement of the slide guide. According to another arrangement, said rear wall is arranged for receiving means for fixing a locking pin (19) capable of cooperating with the horseshoe hook part of the locking lever (12) established from the shutter (8). This locking finger is mounted with articulation capacity against a fourth elastic return means (20) relative to said rear wall of the slide guide. Due to the elastic pressure force, the locking finger is biased towards the rear. Moreover, this locking finger (19) forms on the outer side oriented to the fixed frame a recess (19a) in the form of a hook to cooperate with the bearing plane (7h) of the horizontal upper base of said slide. In this situation, the tongues of the end face of said slide guide are fully extended and the third elastic return means is under maximum tension. It is therefore necessary to describe the fixed frame (7). It essentially comprises a rear plate (7g), an upper horizontal base plate (7b) provided with oblong cutouts (7a) for the passage of the tongues of said slide. The frame has support planes (71) of the upper protection plate. In addition, the fixed frame has flanges (7m) perpendicular to its bottom wall disposed on either side of the aforementioned mechanisms and essentially by their visible edges to guide and support said slide. The fixed frame also receives horizontal support legs of the slide guide by its upper base. The protection plate (4) aims to protect the mechanism and has a rectangular shape corresponding to the dimensions of the module thus formed. It is therefore necessary to explain the operating mode of the dispensing apparatus which is equipped with the mechanisms described above in order to allow only the distribution of wiping materials having imprints in their width, these impressions being reproduced at the same time. identical on the pressure roller. It is also specified that the pressure roller is biased only during the loading phase of the wiping material. It will then be described the means and the reloading phase of the pressure roller. In the loading phase of the web of material comprising continuously marking marks, the pressure roller is in the extended position relative to the plane of the flap, revealing a portion of its periphery facing the complementary shapes of the material strip. In this position, the slide guide is in the up position and the tabs out, the locking lever (12) is held by the locking finger (19), the shutter is in the open position. When the strip of material arranged with its marking zone constituting fingerprints is presented facing the pressure roller in loading situation of the material, the lid of the apparatus being closed, said strip of material penetrates by its opposite part in the corresponding forms. pressure roller (2). The traction action of the web of material by the user or the maintenance operator causes the rotational driving of the pressure roller. This rotation of the pressure roller is carried out on the one hand by driving the eccentric in rotation, in view of the launching of the pressure roller, but also on the part of the rotation of the axis of the pressure roller, this causes the displacement of the arms associated with the locking lever (12). This causes the forward movement of the horseshoe hook and therefore the attraction of the locking finger (19) which escapes at its point of attachment to the fixed frame. This escapement effected by the locking finger, the slide guide will be released against the detent action of the third return means causing the downward descent of the slide guide (7). By the cam effects arranged on the slide guide and the flap, the latter will pivot forwardly in a closed position sufficient for the pressure roller is no longer apparent from the flap. The pressure roller thus retracted has no function and the distribution of wiping material packaged in a reel or folded can normally continue. With regard to this particular implementation, any use of a wiper material of smooth appearance or having a configuration by marking different from that of the pressure roller can not allow a distribution of the material.

This distribution continues until exhaustion of the wiping material. The maintenance operator must then put a new battery or coil of wiping material with the same characteristics. It is therefore necessary to recharge the device that is to say to replace the pressure roller in arming position and overflow of the flap. For this purpose, referring to FIG. 3, the reloading is carried out by actuating the slide guide in an upward movement, this is obtained by the implementation of two cams (21) disposed on each side wall of the cover, in the lower part of it. The cams are profiled to come into contact with the lower part (9n) of the slide guide and cause the bearing to be raised, the articulation of the cover on the passage of the axis (22a) which corresponds in practice to the loading operation of the The dispensing device causes the sliding guide to move upwards, the release of the flap which resumes its open position, due to the effect of the respective cam supports and then the hooking of the locking finger (19) on the fixed frame. The housing is arranged with openings (3.3) of curved shape to allow the passage of said cams (21) when raising the lid. The passage (22b) of hinge axis of the lid on the housing is shown a plate (23) for closing the opening of passage of the cams (21) is also provided in the upper part of the lid. In this configuration the pressure roller overflows again from the plane of the shutter to be activated by the new band of wiping material to be dispensed. The advantages are apparent from the invention. It emphasizes the exclusive operation of the dispensing device with the only strip of wiping material having a marking area and fingerprints identical and complementary to the shapes made on the pressure roller. No strip of smooth material can be dispensed because having no action on the pressure roller which is not moved in position. There is therefore inevitably a jam between the shutter and the cover of the device causing the shutdown of the device. The concept of the invention is applicable not only to the apparatus as described but also to the dispensers of self-cutting wiping material, it suffices to associate the cutting mechanism with the loading mechanism according to the invention. 'invention. The invention responds to the initial problem that is to say to make captive the supply of wiping material with the dispensing device.
