Description

Product Applicator Device Phytosanitary

Object of the invention

The present invention, as expressed by the set forth in this specification, refers to a device Applicator of phytosanitary products, which involves notable relevant and advantageous features compared to those that exist currently and that can be considered of its kind.

The application of wax in a treatment line of fruit, should always be proportional to the amount of fruit that then go through the product application post Phytosanitary At the time of application the fruit advances on some brushes, usually of mane, to facilitate the waxing of the fruit that has been deposited from a depalletizer point, at boxes full of fruit arrive.

It is an object of the invention to automate a task usually performed by the head of the line treatment, which must adapt the quantity of product phytosanitary, to the amount of fruit that passes through the line of treatment.

The amount of fruit may vary. considerable during the workday.

One of the most common reasons is the change of  variety that due to the characteristics of each fruit does not It always allows you to work at the same pace.

Currently in most of the warehouses of fruit conditioning, wax flow regulation is Do it manually. For this reason, the person in charge of the line clothing is required to periodically measure the flow of fruit that passes through the line and adjust the flow rate of wax to Apply.

It is therefore the object of the invention to relieve to the line manager of those tasks and to ensure a correct fruit treatment, since the applicator device that we occupies, adjusts with a short period of time, the flow rate of wax to Apply.

Description of the invention

In general, the applicator device of Phytosanitary products, object of the invention, used both for the application of waxes as fungicides on the fruit that advances in the treatment line, includes a wax applicator determined by a series of rotary discs arranged horizontally, located on a bridge transverse to the brushes Waxing The phytosanitary product access, through appropriate pumps, through a conduit oriented perpendicular to the axis of rotation of the applicator device, breaking the wax when entering contact with the disk that is thus projected by centrifugation in fine drops, on the fruit to be treated. This is how the fragmentation and distribution of the phytosanitary product to all width of the brush curl 5 through which the fruit passes to try.

The transverse bridge or bench includes the 3-phase disc drive motors. The wax arrives by an outer conduit to a coaxial chamber defined between the axis swivel and a fixed envelope.

There is an electrical control panel and a Wax applicator cleaning system.

To have an accurate indication of the fruit that must be treated at all times, three sensors are placed in the treatment line

One of these sensors indicates whether the line of Treatment is in operation or not. Basically, if there isn't Advancement of the fruit in the treatment line is not possible Phytosanitary product application.

Another sensor allows to count the number of boxes of fruit that are turning in the treatment line. East sensor allows to measure, by a simple arithmetic calculation (boxes dumps at the depalletizing station, weight of each box and time counting) the tonnage of fruit that is happening in each moment.

Another sensor lets you know if fruit is entering to the wax applicator. Although advance the tape, if there is an area that does not carry fruit, the product feed is cut Phytosanitary

To facilitate the understanding of characteristics of the invention and forming an integral part of this Descriptive report, accompanying some sheets of plans in whose figures, with an illustrative and non-limiting nature represented the following:

Brief description of the drawings

Figure 2.- It is a sectioned elevation view. longitudinal, of one of the wax or product applicators phytosanitary treatment, also observing the conduit of Feeding the latter.

Description of the preferred embodiment

Referring to the numbering adopted in the figures, we can see how in figure 1 they are referenced with number 1 the three-phase drive motors of the 2 + 12 rotating discs (see figure 2) mounted on the end of the vertical axes 3 of rotation, the motors 1 being fixed to the bridge transverse 4.

The brush curl over which the fruit passes to be treated with phytosanitary products, it is referenced with the number 5 in figure 4. The fruit is transported in boxes that they are received in depalletizer 6, where they pass from chronologically for all the machines that typically ensure washing, selection, drying, treatment and calibration of the fruit (23), this list of operations is not exhaustive.

In figure 2 we see referenced with the number 7 a tubular element of stepped section that is enveloping the axis 3, remaining at a certain radial distance from it to determine an annular chamber in whose lower zone, referenced with the number 8, access the phytosanitary product that arrives through the conduit of respective feeding 9. Figure 1 shows the element distributor 10 of the wax, or phytosanitary product of which try, from which the hoses or access ducts 9 to the different spray heads where the discs are located swivel 2.

The tubular elements 7 are fixed to the lower part of the transverse bridge 4 through its walls respective 11, serving these elements as means of protection. The supply line 9 is connected radially to a hole in the wall of the tubular element 7.

Reference 12 designates elements rotating disc protectors 2 and rotating with them.

Making special reference now to figure 3 where the phytosanitary product control scheme is shown, reference is made to the control panel or number 13 maneuver, linked to connection lines 14, 15 and 16, corresponding to the different sensors discussed above. On the connection line 14 is the sensor 17 (see figure 4) for counting boxes overturned at the depalletizing station corresponding to the conveyor belt 6 prior to that of access to transversal bridge 4 of application of the phytosanitary product.

The connection line 15 corresponds to the sensor operation of the treatment line, and the connection line 16 reaches the location point of the input detection sensor of fruit to the wax applicator. These last two sensors cited allow you to decide at all times whether wax is applied or not, with the obvious savings in wax that this implies, since it only applies When fruit passes These sensors that we are now doing reference, are arranged at the entrance of the wax applicator, while the sensor, or group of sensors for counting boxes, are arranged in the depalletizer 6 as we had indicated above and seen in figure 4.

In figure 3 we see schematically shown the pumps 22 of impulse of the phytosanitary product towards the rotating discs 2, in number of three in this example of embodiment shown in the figures. For the treatment of fruit there is the air line 18, the water line 19 and the wax line 20 in which the respective ones are interspersed solenoid valves 21. One of the purposes of the connections of air 18 and water 19 is the cleaning of disks 2 and elements 12 at End of the work day.
