SUMMARY OF THE INVENTION The present invention aims to fill this void.

[0005]

The method to which the invention relates is therefore to place the shoe in a position that favors the flow of water, and then with respect to the outside of the shoe: -under high pressure, optionally with a cleaning agent. Pre-cleaning with a spray of added water, -under low pressure, cleaning with a spray of water with a cleaning agent and optionally a disinfectant, -under high pressure, rinsing with a spray of water in sequence, And on the inside of the shoe: -under low pressure, cleaning with a spray of water containing detergent and possibly disinfectant, -under low pressure, optionally with water containing disinfectant. It consists of sequential rinsing by spraying, "under low pressure" means the pressure of the water supply network, i.e. approximately 3 bar, and "under high pressure" means a pressure of about 100 to 160 bar.

According to a preferred embodiment of the invention, the rinsing operation on the outside of the shoe is followed by the application of a dust-free protective film by spraying water under low pressure with the addition of a suitable treating agent. ing. The last used treating agent may be, for example, a water-soluble silicone wax.

Advantageously, the inner and outer shoe cleaning operations, which are carried out under low pressure a total of two times, are carried out simultaneously. Furthermore, the inner rinsing operation of the shoe, which is performed under low pressure, is advantageously performed at the same time as the outer protective film application operation, which is also performed under low pressure. Any soap or detergent soluble in water can be used as the cleaning agent, and any disinfectant soluble in water can be used as the disinfectant.

An apparatus for carrying out the method comprises a shoe rack having a plurality of tubular columns, arranged in an airtight cabinet of parallelepipeds opening on at least one side, along the upper part of said cabinet, ie the shoe. Main carriage that can move horizontally on the hangings, means for operating the carriage, means for ensuring reliable water supply, and means for receiving and discharging used processing liquid Essentially having means, the tubular columns being oriented from their fixed ends from bottom to top and arranged to form rows along vertical columns and horizontal rows, the treatment liquid inside the shoe Their free ends are perforated to allow the flow of fluid, and each tubular post is adapted to receive and support a shoe hung on its axis, said main carriages each having a second
A carriage is mounted and supports two vertical guide rails arranged on both sides of the shoe rack so as to pass through vertical planes located in front of and behind the shoe rack, each of the second carriages being on the outside of the shoe. Supporting two nozzles for spraying the treatment liquid, a low pressure nozzle and a high pressure nozzle, said operating means is such that the main carriage is in front of each vertical row of shoes each time the second carriage completes a vertical run. The main carriage is operated to move forward one pitch at a time so as to be stopped, and after each pitch of the main carriage is operated, the second carriage is operated to vertically move up or down completely.
According to the length of one cycle of this method, a desired processing liquid is supplied to the tubular column of the shoe rack and the nozzle of the second carriage under low pressure or high pressure.

The means for supplying the low-pressure treatment liquid to the low-pressure spray nozzle of each second carriage and the tubular column of the shoe rack is from a common valve connected to a general water supply pipe network to a common pipe divided into two branch pipes. And each branch is provided with a low pressure nozzle and a circuit with two parallel branches, each equipped with an on-off valve and an injector used to collect the relevant treating agent in the tank. Connected to the tubular column.

In order to avoid the risk of malfunction of the device when the water supply pressure to the water supply network is reduced or water supply is stopped, the water pressure of the water supply network is set at a predetermined threshold value downstream of the connection valve with the water supply network. It is advantageous to have a constant pressure device which, if reduced to below, instructs the device to be stopped by stopping the supply of electricity.

The means for supplying the high-pressure treatment liquid to the high-pressure spray nozzle of each second carriage is a high-pressure pipe in which an on-off valve, a high-pressure pump, and an injector used for collecting the treatment agent in the tank are attached in series, It is parallel to the low-pressure water supply pipe.

The guide rails for the main carriage and for each second carriage preferably comprise end-of-travel detectors, the circuit of which is connected to an electrical and electronic set which controls the operation of the device and all valves It is a solenoid valve, the control circuit of which is also connected to a control set, which further has a delay mechanism which is adjusted by coupling with the detector of the end of travel of the carriage and the solenoid valve.

According to a simple embodiment of this device, the means for collecting and draining the used processing liquid comprises a collecting tank for this liquid arranged under the shoe rack and a suction for this liquid in the collecting tank, It is composed of a low-pressure pump that discharges it into a desired container or pipe.

In accordance with an advantageous feature of the invention, each tubular post of the shoe rack is capped with a clearance cap for support held away therefrom. Therefore, on the other hand,
The shoe does not have the possibility of blocking the outlet opening of the tubular column that supports it, while the water which constantly flows along the inner wall of the shoe cannot flow into this tubular column again. According to a further feature of the invention, the shoe rack is removably mounted in the cabinet, that is to say it is arranged in the cabinet before treatment and can be removed after treatment.

This arrangement makes it possible to dry the shoe after the treatment outside the device so that the shoe can be placed on the shoe rack before the treatment and the shoe pre-placed on the other shoe rack can be treated. In any event, the present invention illustrates, by way of non-limiting example, one embodiment of the device of the present invention, which is best understood by the following description with reference to the accompanying schematic drawings illustrating the operation of the device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in particular detail in FIGS. 1 and 2, all the features of this device are housed in a parallelepiped-shaped airtight cabinet 1, the six sides of which are front wall 2, rear wall 3, It is closed by six wall surfaces of two side wall surfaces 4, 5, an upper wall surface 6 and a lower wall surface 7. In the example shown in the drawings, the front wall surface 2 is constituted by a wall surface that can be opened.

Inside this cabinet 1 is placed a shoe rack 8 having a plurality of tubular columns 9 arranged in rows along vertical columns or columns 11 and horizontal columns 12. Each tubular column 9 is supported by the shoe rack 8 so as to incline from the bottom end to the top end from the fixed end portion to the shoe rack 8. Furthermore, the tubular column 9 is inclined with respect to this right-angled direction so that its longitudinal axis 9a does not lie in a vertical plane oriented at right angles to the front wall 2 and the rear wall 3 of the cabinet, and for reasons which will be explained later. Is arranged as.

The main carriage 13 is supported by the upper edge portions of the front wall surface 2 and the rear wall surface 3 of the cabinet 1 and moves horizontally on horizontal rails 14 and 15 extending substantially in the front width of these wall surfaces. The drive of the main cabinet 13 from one end to the other of this horizontal course is ensured by a motor 16 placed in the cabinet 1, the motor output shaft 16a
By means of the bending pinions 19 and 21 and the return pinion 22, two straight portions 18a parallel to the rails 14 and 15,
A chain 18 adapted to form 18b bears the pinion 17, which is meshed with it.

As also shown in FIGS. 1 and 2, the main carriage 13 supports two vertical guide rails arranged on both sides of the shoe rack 8, namely a front guide rail 23 and a rear guide rail 24. As a result, when the main carriage 13 moves on its horizontal course, the guide rails 23 and 24 pass through vertical planes located in front of and behind the shoe rack 8. A second carriage 25 is mounted on each of these guide rails and is movable over the entire height of the combined guide rails.

In order to improve the vertical posture of each guide rail 23, 24, horizontal rails 26, 27 supporting casters 28, 29 respectively at the lower ends of the front wall surface 2 and the rear wall surface 3, which are the corresponding vertical wall surfaces. Casters 2
The vertical axes of 8 and 29 correspond to the corresponding guide rails 2.
Carry-on 31, 32 supported by the lower ends of 3, 24
Supported by.

A shaft 35, which can be rotationally driven by a motor 36, has one end of one of the guide rails 23 and 24 so that it is oriented at right angles to the front wall surface 2 and the rear wall surface 3 of the cabinet 1. So that it is located above the top edge,
It is supported by the main carriage 13. Each end of this shaft 35 carries a pinion 37 with which a chain 38, which is adapted to be returned by a lower pinion 39 supported by the lower ends of the guide rails 23, 24, meshes.

Due to this arrangement, each second carriage 25
Can pass over the entire wall of the shoe rack in front of it. As pointed out earlier, the tubular column 9 of the shoe rack 8 is tubular and is connected by vertical and horizontal auxiliary tubes 41 and 42 to a source of processing liquid which will be described later.
Furthermore, each tubular column 9 has at its free end a distribution port 43 for the treatment liquid for the inner treatment of the shoe to be treated.

As previously pointed out, each tubular post is adapted to receive a shoe 44 to be treated hung on its shaft so that drainage of the treated liquid facilitates drainage. Is arranged to. 1 and 2, each tubular column 9 is, in the example shown in the figures, covered with a gap cap 45 made up of two metal wires arranged 90 ° to each other, The longitudinal branch extends over the entire length of the tubular column 9.

As for the cap 45 having these gaps, the shoe 44 supported by the tubular column has the processing liquid distribution port 4
By avoiding the risk of blocking 3 the contact with the corresponding tubular column 9 does not result in a post-treatment liquid flow on the one hand and on the other hand a backflow of the liquid inside the tubular column 9 after the treatment. Absent. Further, each second carriage 25 has two nozzles, namely a low pressure nozzle 25a and a high pressure nozzle 25b, on the outer surface of the shoe 44 to be treated so that the treatment liquid can be surely distributed by spraying.

FIG. 3 shows the operating principle of this device.
According to this principle, the operation means, which are of an electronic type and an electric type, and which are gathered in a case 46 provided in a part of the left side wall surface 4 of the cabinet 1, include the drive motor 16 of the main carriage 13 and the second carriage 25. The electric power is reliably supplied to the simultaneous drive motor 36 of the main carriage 13, so that the main carriage 13 stops clearly at the end of each unit traveling 47 as shown in FIG.
As the carriage 25 moves up and down the vertical course of the guide rails 23 and 24, the unit run 47, which corresponds approximately to the gap separating the two vertical rows 11 of tubular columns 9, is advanced one pitch at a time.

The vertical ascending or descending course of the second carriage 25 is limited by the end-of-travel detectors 20 and 30, and these detectors make up the main carriage 13.
The unit course is controlled. Further, the entire horizontal movement of the main carriage 13 requires the detectors 40 and 50 to be connected to the respective end portions.
Limited by

The arrangement in which the axis 9a of the tubular column 9 of the shoe rack 8 is inclined with respect to a vertical plane parallel to the side walls 4 and 5 of the cabinet 1 is such that two side faces of the shoe 44 to be treated have two first sides. There is an advantage that the processing liquid jetted by the nozzles 25a and 25b of the two-carriage 25 reaches well.

The overall operating cycle of this device is as follows. During a complete run of the upper main carriage 13 corresponding to a plurality of vertical ascending and descending vertical runs of the second carriage 25, an outer pre-wash of the shoe 44 with or without detergent is carried out under high pressure, i.e. 100-160 bar. Under the pressure of
The spray is performed by the high pressure nozzle 25b. This pre-washing operation has the effect of removing even the largest dust from the shoes 44.

When the carriage set is returned to the starting position,
A second operation is initiated in which the outer and inner treatments of the shoe 44 are performed simultaneously. The outer processing stage of the shoe 44 includes the second carriage 25.
The cleaning liquid is sprayed under a low pressure, that is, under a pressure of about 3 bar by the low pressure nozzle 25a. This detergent solution
It consists of water with detergent added, which can consist of any water-soluble detergent, and the concentration of the wash liquor is adjusted to the desired value comprised between 1 and 15%.

The wash liquor can also be added with a disinfectant, which can consist of any water-soluble disinfectant. The presence of antiseptics is necessary, especially when the shoes to be treated are used by people working in the produce food industry.

During this stage of the outer treatment of the shoe 44, the shoe 4
4 inside processing stage, namely the distribution port 4 of the tubular post 9.
According to 3, it is possible to perform the treatment by spraying a cleaning liquid composed of water to which a water-soluble detergent is added. For the outer treatment step mentioned above, when shoes are used in the agricultural food industry, it is advantageous, or even essential, to add a disinfectant to the detergent, which can comprise any water-soluble disinfectant.

The inner treatment step of the shoe is carried out under low pressure, ie at a pressure of approximately 3 bar, which corresponds to the pressure of a typical water supply network. When this washing step has been carried out, the set of main carriage 13 and second carriage 25 is returned to the starting position in order to be able to carry out the steps according to the operating cycle of this device for washing shoes both outside and inside. The outer rinsing of the shoe is carried out by means of the high-pressure nozzle 25b of the second carriage 25, which supplies water under high pressure (100-160 bar).

The device is further capable of performing other steps for outer treatment of the shoe 44. At this end of the process, the outer surface of each shoe is coated with a protective coating to reduce dirt buildup at the end of the process, so that the silicone wax or similar is applied to the low pressure nozzle 25a so that it retains its properties for a long period of time. To spray the shoes 44.

At the same time or at a time, the second and final stage of the internal treatment of the shoes 44, which consists of a rinsing operation, is carried out across the tubular columns 9 and the distribution openings 43, whereby the inside of each shoe 44 is A rinse solution composed of water is injected.
Of course, the entire mechanism for operating the various stages of the operating cycle of the device can change this operating characteristic, optionally and depending on the field of use of the shoe and thus on the extent of the litter.

As FIG. 1 shows in more detail, the lower wall 7 of the cabinet 1 is slightly curved in the middle as shown, the low point allowing for the recovery and drainage of processing liquid after use. FIG. 4 shows an embodiment of a water circuit for distributing the treatment liquid to the low pressure spray nozzle 25 a, the high pressure spray nozzle 25 b and the tubular column 9.

As this figure shows, no matter what treatment is performed, washing or rinsing, there is provided a liquid medium consisting of water to which the treatment agent is added by means of a Venturi type injector. For processing under low pressure, a main pipe 48 is provided which can be connected to the general water supply pipe network through the on-off valve 10. This main pipe 48 connects the water from the water supply network to
Low pressure spray nozzle 25 of tubular pillar 9 and second carriage 25
It is divided into two branch pipes 49 and 51, each pointing towards a.

Each branch pipe 49 or 51 is provided with two branch pipes 49a, 49b between the downstream end and the upstream end connected to the tubular column 9 and the low pressure spray nozzle 25a, respectively.
And 51a, 51b, each branch having an on-off valve 49'a, 49'b and 51'a, 51'b.
Venturi injectors 49 ″ downstream of this valve respectively
a, 49 "b and 51" a, 51 "b. Each injector has its own associated tank 49 '" a, 49 "'.
b and 51 ″ ″ a, 51 ″ ″ b can be withdrawn.

All valves in this flow path consist of solenoid valves or similar valves, and the operation of this flow path is not completely automatic depending on which stage in the operating cycle it is. Understood in a container. The water supply passage from which the general water supply network is exposed via the valve 10 can be generally shut off or depressurized in order to eliminate the risk of malfunction of the device, and downstream of the valve 10, the water supply network is When the pressure of drops below a specified value,
A constant pressure device 10a is provided so that the operation of this device is stopped by stopping the supply of electricity.

As previously pointed out, the second carriage 2
Only the high pressure nozzle 25b of No. 5 is necessary to supply the processing liquid under high pressure. Therefore, the supply pipe 51 of the low-pressure nozzle 25a is divided into a branch pipe 49 directed toward the tubular column 9 of the shoe rack 8 and two branch pipes 51a and 51b unique to each process. A high-pressure pipe 57 is provided between the high-pressure pipe and the point, and the on-off valve 59 and the high-pressure pump 5 are connected in series to the high-pressure pipe.
8 and the on-off valve 62b, the injector 62 connected to the processing agent tank 62a is provided, and the downstream end of this high-pressure pipe 57 is connected to the high-pressure nozzle 25b of each second carriage 25.

During the low pressure processing cycle with the low pressure nozzle,
It is sufficient to keep the on-off valve 59 in the closed position and open it when the high-pressure processing agent is to be distributed through the high-pressure nozzle 25b, and the on-off valves 49'a, 49'b, 51 'are sufficient.
a, 51'b control the low pressure water supply of the tubular column 9 and the low pressure nozzle 25a which is then closed.

As pointed out earlier, the lower wall surface 7 of the cabinet 1 is slightly curved to assume the shape of a collection tank. Further, as shown in FIG. 4, this means for reliably emptying the recovery tank 7 has a low-pressure pump 52 connected by a pipe 53 to a reservoir suitable for recovering the taken-out material.

In order to facilitate the starting of the pump 52, on the one hand the pipe 53 is connected to the main pipe 48 by means of a second pipe 53a equipped with an on-off valve 54, and on the other hand the pipe 53 is a second pipe.
An opening / closing valve 55 is provided downstream of the connection portion with the pipe 53a. Therefore, in order to start the pump 52, the valve 10
After opening, it is sufficient to open valve 54 with valve 55 still closed, then shortly thereafter to close valve 54 and valve 10 and open valve 55.

Of course, not only the speed of the various main carriages 13 or the second carriage 25, but also the discharge rate of the various pumps or injectors used to dispense the treatment agent, the operator arranges a number of adjusting means, As a result, the operation of this device can be adjusted to be fully compatible with the conditions of use of the shoe 44 being processed.

In the example shown in the drawings, the shoe rack 8 is fixedly mounted in the cabinet 1. This shoe rack 8
Without major difficulty, for example, the lower wall surface 7 of the cabinet 1.
It is easy to conceive to be removably mounted by providing a rotating caster and a treatment agent source and a gas tight quick-joint means on the rails provided in the. This arrangement allows the shoe rack 8 to be mounted and removed outside the cabinet 1 so that other processing can take place. Furthermore, each shoe rack 8 can also be used to introduce treated shoes into an incinerator or tunnel.
