Definitions

• the present invention relates to an improvement in the guiding device of products of the bottle or bottle type on a conveyor, a conveyor table or the like.
• the conveyor comprises a guiding device which comprises guides themselves and supports for these guides, regularly distributed, which supports are fixed on the structure of the conveyor.
• guides and guide supports represent an important part of the equipment. These are multiple pieces that run along the conveyors or conveying tables on each side.
• the conveyed products are frequently in contact with the lateral guides and this contact can cause alterations, or even deteriorations, on the products and in particular on the labels.
• the present invention provides an adjustment to these guides to better preserve the state of the products during their conveyance avoiding rubbing them, sometimes with significant pressure, sui * fragile areas like the "déc ⁇ iées areas labeled by example.
• the guide according to the invention consists of two parts:
• thermoplastic material which is clipped onto said rail, by means of hook-shaped fasteners which are arranged at the top and bottom of said profile, which profile is shaped with a variable section over its entire height, and this variation of section gives it a slight and regular slope, from top to bottom, which allows to privilege the contact between the product and the profile at the bottom of said product, that is to say in an area that n is not loaded with decorative forms or the label and which, in general, is the most resistant part of the product.
• the thickness of the profile (12) of thermoplastic material is of the order of 1 mm at its upper part and of the order of 3 mm at its lower part. This difference in thickness of the profile also makes it possible to always offer the product a contact located at the bottom of the guide and this even if said guide tends to bend because of its door-to-door position.
• the profile is obtained by extrusion with, at its guide surface, a concavity which allows its clamping on the rail during the establishment of its fastening hooks on said rail.
• the profile comprises a layout of the kind keying, which arrangement is disposed on the edge of the lower hook.
• the support rail of the profile comprises a longitudinal rib which allows, on the one hand, the rigidificr and, on the other hand, to house the head of the screws which serve to fix it on the means of support.
• This arrangement provides a uniform guiding surface without holes or asperities, which further reduces the risk of deterioration and preserves the condition of the surface of the products.
• the longitudinal rib of the support rail is located in the lower part of said rail so as to increase the inertia of its lower part and reduce its deformation capacity under the pressure of the products.
• the distance between the axis of the longitudinal groove and the lower part of the guide is, for example, between 1/3 and 1/4 of the height of said guide.
• FIG. 1 shows, in the form of a sectional elevation, a guide device according to the invention, installed on the structure of a conveyor,
• FIG. 2 shows the profile made of thermoplastic material, which serves as a friction surface for the guide
• FIG. 3 shows the detail, on a larger scale, the development of the keying type that allows to properly install the profile on the rail that serves as a support.
• the guiding device is installed laterally on the structure (1) of a conveyor or the like.
• This guiding device comprises a support (2) which is fixed to the structure (1) and a guide (3) proper, which guide (3) is integral with said support (2).
• the support (2) consists, for example, of a metal monoblock piece of suitable material, preferably a stainless material.
• This support (2) is shaped from a cylindrical bar, by any suitable means such as, for example, a hot stamping operation.
• L-shaped part comprises a foot (5) which is fixed on the conveyor structure (1) and a fold (6) which makes the junction between said foot (5) and said rod (4).
• the fold (6) makes an obtuse angle with both the foot (5) and the rod (4).
• the length of the fold (6) allows to deport the rod (4) relative to the foot (5) and leave enough space to accommodate the guide (3) which, in many cases, does not encroach on the conveyor .
• the guide (3) is carried by a bar (7) cylindrical, which bar cooperates with a nut (8) which is threaded on the rod (4) of the support (2).
• the guide (3) consists of two pieces:
• This profile (12) is made of thermoplastic material, obtained by appropriate means of the spinning or extrusion type, for example.
• the rail (11) is made of thin sheet metal and has a rib (13) for stiffening which gives it a certain inertia.
• This rib (13) also accommodates the head of the screw (14) which allows to fix the rail (1 1) of the guide (3) on the end of the bar (7).
• This arrangement allows to have a sliding surface for the guide (3) without any roughness, which avoids any retention of waste, dirt or otherwise, likely to contaminate the products transported by the conveyor.
• the groove (13) is preferably arranged in the lower part of said guide.
• the axis (15) of this groove (13) is at a distance D from the lower part of the guide (3) which is, for example, between 1/3 and 1/4 of the height G of said guide.
• this kind of guide (3) has a height of the order of 10 cm and its level, relative to the conveying surface, is of the order of 1 to 2 cm approximately.
• the fixing of the rail (1 1) of the guide (3) can also be performed by means of a yoke, not shown, said yoke being fixed in the same way, discreetly by bolts whose head is embedded in the rib (13).
• the mounting of the rail (1 1) with a clevis gives more possibility of adjustments and flexibility for its installation on the support (2).
• Figure 2 shows the section of the profile (12) which acts as a friction surface. This profile has several features that improve the structure of the guide (3) and the guide.
• the accuracy of the guidance obtained thanks to the support (2), in particular, is further improved by the arrangement of the profile (12).
• the active surface of the profile (12) has a thickness that varies between the top and the bottom of the guide (3); the thickness H at the upper part of the profile (12) is smaller than the thickness B of the same profile at the bottom of said profile.
• This difference makes it possible to correctly guide the products while limiting as much as possible the contact surface between these products and the profile (12) of the guide (3).
• the guiding is carried out in the lower part of the products, that is to say in an area which is generally less fragile than the area of the label, for example, in the case of products like bottles or flasks.
• the profile (12) has hook-shaped arrangements at its top and bottom.
• hooks (16) and (17) allow to clip this profile (12) on the rail (1 1) and its adhesion to the latter is reinforced almost naturally by the shape that is given to the friction surface of this profile (12). ) at the time of manufacture.
• the friction surface of the profile (12) is indeed shaped with a concave curvature, as shown in FIG. 2, which makes it possible to press the central portion of said surface onto the rail (1 1) and to adhere said profile (12). to the latter.
• a mark is arranged on its lower part, on the edge of the hook (17), as shown in Figure 3.
• This mark acts as a deceptive; it is made under the hook (17) and consists of a recess (18) which forms a groove along the length of the profile (12).
