Description

Improvements in patent No. P 200002508 referent a: "Cutlery and article dryer and polishing machine table metal. "

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to the improvements introduced in an automatic dryer tabletop machine and cutlery and tableware polish, which has been described in patent application number 200002508 and designed and made to obtain numerous and notable advantages over other existing machines of analogous purposes.

This type of machines consist mainly of a container chamber supported on springs and connected to an engine vibrator, whose chamber has an entrance and an exit hole where the union of these gives rise to a ramp where the cutlery ascend intermingled with a drying product, leaving the cutlery and other polished metal utensils when performing route, until reaching the outside through the outlet.

Starting from this the invention is provided so that the vibrating motor is housed inside the chamber container, so that the height of the machine is reduced and gives place to a new cutlery dryer and polishing machine, equipped with small dimensions. The camera has been gifted container of a new configuration to allow accommodation of the vibrating motor and in turn an optimization of the task of drying and polishing cutlery due to the new container chamber configuration. This set of changes gives place to an automatic machine to dry and polish cutlery suitable for working on a table making it, in this way, much more operational and accessible at the time of its operation.

Background of the invention

Machines intended for polishing of certain pieces, which include a chamber containing the pieces to be polished and that are equipped with an inlet and another exit, among which the bottom of the camera defines a path, preferably of spiral layout, with or without slope.

The camera is mounted on elastic supports, composed of springs. In addition the camera is connected to an engine vibrator. A mass of abrasive particles, with which the articles intermingle with polish or dry When the vibrating motor is started, the chamber transmits vibrations to the abrasive product and to the polishing items A polishing and cleaning action of the articles and an advance of them along the path that defines the bottom of the receptacle, from the inlet to the output In this sense, for example, patents can be cited US 3407542 and US 4018009, as well as the German DE patent 1226906.

With the same principle is known by the EP 0882424, a machine for drying, polishing and polishing cutlery and table utensils, in which the bottom of the chamber defines, between the mouth of entry and exit, a substantially horizontal path, and in which the product contained in the camera, to carry out The drying, polishing and polishing operations consist of a drying material, for example of vegetable origin. Otherwise, the tank is supported by springs and is connected to an engine vibrator, through which a contact and friction is achieved constants between cutlery or tableware and material secant, as well as a continuous advance of said cutlery from the mouth of entrance until the one of exit.

In the machines described that present several problems. The first of these are the traffic jams that occur in the inlet and inside the container chamber between Cutlery and other metal utensils. The second problem that present is that the cutlery or table utensils leave the machine with adhering particles of the drying material with which It requires a subsequent final cleaning process. The third problem is the excessive vibration that should be given to the cutlery in the last stretch of exit so that they get rid of as much of possible drying material, mistreating in this process excessively the covered. And finally the excessive height, characteristic of the machine that prevents this is suitable for mounting in some establishments

Description of the invention

The machine of the invention presents a new structure on which the vibrating motor with which it goes equipped is housed in the same horizontal plane as the camera container inside a central cavity, this results in a series of particularities that derive in advantages, both functional and of efficiency and cost savings; in addition to a very important reduction in size, with respect to those known and cited in the previous section, also obtained thanks to the relocation of vibrating motor and the change in anchoring fasteners of others structural elements.

The dryer and polishing machine object of the invention also based on that for drying and polishing uses a container chamber in which a path is defined from the entrance to the exit through which covered and other metal table utensils intermingled with the material secant advance thanks to the vibrations transmitted by the engine vibrator with which it is equipped.

To solve the problems of the state of the technique, the machine of the invention presents as the first particularity an oval-shaped container chamber, eliminating at the beginning any corner that could hinder the Cutlery tour and other tableware. It has also removed the downward ramp that communicated the hole input with the lower zone of the container chamber; so that cutlery and other tableware now fall directly in a lower section, in a cornered shape, of said chamber through of the entrance hole, thus avoiding the numerous traffic jams that occurred in this area. The entrance mouth and the mouth of exit are located at different height, leaving the outlet below the entrance mouth. Both mouths are joined by a helical track ramp. The ramp mentioned above in your upper end part, which flows into the exit hole, has a perforated section, where the dimensions of said perforations They are larger than the particles of the drying material.

These perforations make the most of drying material falls back through the holes to the initial part of the route. In the machine described here this section has been made of shorter length so that the cutlery withstand for less Direct vibration time with the area of the perforated ramp and so they are less beaten; which supposes two advantages: that a decrease in machine working noise and less abuse of cutlery

The machine that advocates, manages to solve the problem of the drying material adhered to the cutlery and others metal tableware placing over the final part of the run a fan with hot air supply in direction falling. Element that together with the upper end section with larger perforations that the drying product get that cutlery and other metal utensils come out dry, polished and free of adhering particles of the material drying.

This fan has a built-in heat resistance that makes the expelled air hot. This apart from the advantage explained in the previous paragraph, also causes the sawdust of the entire container to remain at a high temperature, thus preventing it from reaching a high degree of humidity and Become a pasty material.

Therefore cutlery and other utensils Metallic table are introduced through the entrance and remain housed in the container chamber and begins to ascend the ramp towards the exit mouth thanks to the vibrations transmitted by the vibrating motor

Before leaving through the exit mouth to the outside the cutlery crosses a last section that thanks to the perforations that it possesses allows the particles of the material blotter fall through those perforations and therefore leave that last free section of said particles of drying material. He vibrating movement that accompanies cutlery and others utensils along the entire route facilitates the particles of drying material fall through the holes of the last section of the ramp.

The above is completed and complemented by the hot air of the fan in descending direction, which withdraws the possible particles attached to the cutlery that have exceeded the perforated section before reaching the outlet. Finally cutlery and other metal utensils reach outside by the mouth of exit totally dry, bright and without remains of particles of drying material. Doing the drying process and polished much cleaner and hygienic, while fast and effective. The cutlery dryer and polishing machine and others metallic table utensils object of the description can also have a germicidal lamp placed in such a way that it remains on top of the ramp in one of its sections, so that covered and table utensils are exposed to their action when crossing the section on which said lamp is placed, making this Mode drying and polishing of cutlery much more hygienic. Said germicidal lamp would emit ultraviolet radiation, and would be mounted on a removable device.

Other device that may be equipped said machine at the outlet, are flexible closing sheets, that allow the passage of cutlery and utensils but not of the exit to the outside of both the particles of the material secant as the air produced by the fan, while isolating the outside of part of the working noise of the machine. To isolate the working noise of the machine has also been provided to the machine of a plastic cover that covers approximately half from the top of the container chamber.

The perforated ramp is made of a plastic material which gives it less stiffness which prevents cutlery and other table items are unnecessarily mistreated at the same time that is greatly diminished in work noise.

Finally, the machine of the invention includes also as a novelty feature its decrease in height, regarding the known ones. The dryer and brightener machine get this height reduction thanks to the camera container has been configured leaving a cavity in its part central that allows the housing of the vibrating motor.

This eliminates the support chassis in the that this vibrating motor and the springs were staying. In this new machine the container chamber rests directly on the set of springs and these in turn at the base of the machine.

Detailed description of one embodiment

According to the figures presented to illustrative and non-limiting example title, the dryer machine and brightener is fed with cutlery and other utensils table metal dropping them through the inlet or hopper central (1), until it flows into a container chamber (2) and begin to ascend the ramp (3), until reaching the mouth of mouth outlet or hopper (4), located below the inlet or central hopper (1).

These are two hoppers, central (1) and of mouth (4) those that define the ramp (3) through which they run upwards the cutlery thanks to the vibration. This vibration that occurs when starting a vibrating motor (5), placed in a cavity of the container chamber (2) created to accommodate it, so that we avoid placing said vibrating motor (5) in a chassis for its support and this allows us A large decrease in machine height.

Thanks to this vibration the cutlery and others utensils are subjected to continuous friction with the material secant vegetable that thus performs drying and polishing along the route along the ramp (3), until reaching one last section (6) of the ramp (3). Said last section (6), is drilled by holes with a diameter much larger than the diameter of the drying plant material allowing this material to pass plant by said last section (6) this one returns to the beginning of the ramp (3).

Above the last section (6) the hot air fan (7). The fan (7) is protected by a cover (8), which protects the fan (7) and forms a angle of about 120º between the upper portion of the roof (8) and a lateral portion, which makes the air more directly over the desired area.

Said fan (7) throws hot air into descending direction making the drying plant material not go outside through the outlet (4) and getting removed any remainder of said drying plant material that may remain adhered to the cutlery before going abroad.

That air released also serves to heat the drying plant material so that it returns to the beginning of the ramp at a suitable temperature to dry the Cutlery and other pieces.

The machine also has a lamp (9) of ultraviolet rays, which is placed on top of the ramp (3). The lamp (9) is held by a device (10) Fully removable, which provides an improvement when operating with said lamp (9). This lamp (9) sanitizes the entire process by influence its rays and both on cutlery and plant material secant, disinfecting them in this way continuously.

In the mouth hopper (4) they will be placed some curtains (11) of flexible plastic material, which will prevent remains of the drying plant material go outside and that produce hot air losses, but thanks to its flexibility in any case will prevent the passage of cutlery and other materials

At the top of the ramp (3), approximately one piece is placed as a lid on the end plastic (12), whose main function is to reduce the noise of work by isolating said area and avoid that due to the air fan (7) particles of plant drying material leave at Exterior.

The container chamber (2), is directly supported on four springs (13), which rest on a base (14), saving with this new arrangement the placement of a chassis for supporting said container chamber (2).
