PT88696B - HALOGENING MACHINE FOR TRATMEMT WITH CHEMICALS SUITABLE FOR THE COLLAGE OF SOLES FOR CALCULATION, WITH FILTER FOR THE DEPURATION OF WASTE - Google Patents

Abstract

This is a novel machine for spraying, onto the sole of footwear, liquids for preparing for the sole's having glue applied to it. The machine has a pressurized tank which gives out the halogenating liquid which is sprayed as a mist by an oscillating gun with interchangeable nozzles and completely and homogeneously impregnates the soles. The machine has a filter for collecting and purifying harmful fumes. <IMAGE>

HALOGENATING MACHINE FOR TREATMENT WITH CHEMICALS

SUITABLE TO ADHESIVE SOLES FOR FOOTWEAR, WITH FILTER

FOR WASTE CLEANING

this liquid is vaporized by an oscillating gun with an interchangeable nozzle1, which impregnates the sole perfectly and evenly. The machine is equipped with a filter to neutralize and purify harmful fumes.

Even today, before the streak of polyurethane-based adhesives on soles to be applied to the upper in shoes, dormant chemicals must be used (mixture of solvents with trichloroisocyanuric acid in solution); in specificity these are rubber soles, whether natural or synthetic (SBR):

This procedure, which is essential to obtain compatibility between the adhesive and the surface to be glued, is currently carried out manually with brushes or similar instruments.

With particular reference to the drawings which are included by way of non-limiting example and which are sufficient for the expert either to carry out the invention or to appreciate its outstanding characteristics, a practical embodiment of the invention is illustrated below.

The machine, with movement of the sole in line (fig. I) or rotating (fig. 2), is equipped with a pressure spraying system composed, in its essential parts by a reservoir (A), by a pair of valves ( BI and B2), by an oscillating gun (C), by a movable soleplate (Dl, D2), by an aspirating group (El) and / or filter (F) (fig. 3).

reservoir containing the halogenating preparation is always subjected to pressure. It is only depressurized at the time of loading. The valve (BI part.4) is inserted into the hole (Al).

Each valve (BI and B2) is composed of an upper hollow body (BA) screwed to a lower hollow body (BC) compressing the edge of an elastic membrane (BB); Air is introduced into said upper hollow body from the tube (BF) at a pressure that will impel the plunger (BD) con-4-

draw the elastic membrane with a needle (BE) which, lowering, fills the hole (BF) into which the liquid that is sprayed through the nozzle passes; by increasing the pressure of the liquid (which enters through BG), the elastic membrane is raised, reestablishing the passage of the same liquid.

The valves open and close at the same time to prevent the valves from being closed in the event of a lack of air in the tubes, preventing air from escaping. In order to open the valves, and therefore allow the liquid to pass, the pressure in the reservoir is increased during the passage of the sole under the nozzle of the gun.

The gun (C), which is connected to the end valve (B2), has a continuous oscillating movement to spray, with an optimum angle, on the soles that are placed on a movable plane, which can be rotated (fig. 2) or in line (fig. 1); the pistol (C) sprays only during the passage of the sole and, in its terminal part, an injector nozzle (G) is mounted which creates a nebulization cone with optimum opening in relation to the type of sole. Nozzles can be inserted into the gun with a different spray angle.

Both the angle of oscillation and the period of oscillation of the gun are adjustable.

The fumes created by the evaporation of the solution inside the machine, which is closed except at the point of entry and exit of the soles, are directed through the vacuum cleaner (E), or to the outside, or to the filter (F) provided with a tank (Fl) filled with water and a percentage of products suitable for creating an alkaline medium (pH greater than 9). A tube (F2) is placed inside the tank (F2) with laterally welded other smaller and punctured tubes. From the holes in the small tubes, the fumes come out which come into contact with the 5-

with the solution contained in the same tank.

These are the schematic modalities sufficient for the experienced person to carry out the patent; consequently, in concrete application, there may be variations without prejudice to the substance of the innovative concept.

Therefore, they refer to the preceding description and the drawings together with the presented claims.

Claims (4)

CLAIMS l ^â . - Halogenating machine for treatment with chemicals suitable for bonding shoe soles, with filter for purification, characterized by the fact that it has a reservoir kept constantly under pressure, containing the halogenating liquid, and having a pair of valves that open and close simultaneously , allowing the passage of the liquid only in the presence of the sole to be soaked, which is placed on a rotating or translatable mobile plane in line, to have an oscillating gun with a predeterminable angle and period1, and with, in the end piece, an injector tip i avve1. 2 ^? . Machine according to the previous claim, characterized in that each valve has an upper hollow body screwed to a lower hollow body compressing the edge of the elastic membrane; air is introduced into said upper hollow body at a pressure to impel the plunger against the elastic membrane with a needle that, lowering, fills the hole into which the liquid passes, which is sprinkled by the interchangeable nozzle1 by decreasing the pressure of the piston; the liquid in pressure through the hole to raise the elastic membrane reestablishing the passage of the liquid through the hole. 33. - Machine according to claims 1 and 2, characterized by the fact that it has a spray gun with adjustable tilting movement, both in amplitude and in the period of oscillation. 4 ^{4 5} . - Machine according to claims 1, 2 and 3, characterized by the fact that the excess liquid is aspirated and pushed into a filter made up of a tub containing an alkaline solution and a tube with some small welded and pierced tubes, fumes come out of the quarters and come in contact with the solution contained in the tank. 5-. - Halogenating machine for treatment with chemicals suitable for bonding shoe soles, with filter for purification, characterized by the fact that it has two valves, one connected to the reservoir and one connected to the pistol, each composed of a hollow upper body screwed to a lower hollow body compressing the edge of an elastic membrane; inside said upper hollow body, air is introduced at a pressure so as to urge a plunger against the elastic membrane with a needle which, lowering, closes the hole into which the liquid that is sprayed by the nozzle passes; when increasing the pressure of the liquid, raise the membrane, with the needle attached to it, restoring the passage of the liquid.
