Abstract

System for monitoring the speed of a shaft with linear movement, used in apparatus, devices and elements for dosing and mixing liquid products, characterized by being formed of two distinct parts, first the measuring element (2 ), comprising a sensor shaped probe and the other, the part of electronic control (1) covering the sensor element corresponding position signals and handles, according to preset programming of the electronic management process machine, with means for producing a stop, cutting compressed air supply (4) or power (5), and a light and acoustic signal (7) indicating the occurrence of a failure and the reason for such failure and, in the same way with options to act on the traveling speed of the shaft at all times the possibility to position as many points where you can reverse the movement of m echanism and electronically regulate the positions and paths of the control element can thus select the shift range.

Description

Single axis speed monitoring system with linear displacement

Object of the invention

The present specification refers to a new single axis speed monitoring system with linear displacement with alarm based on differences in machine movement in normal behavior and in behavior under failure.

This invention has its application within the industry dedicated to the manufacture of apparatus, devices and elements for the dosing and mixing of liquid products in general.

Background of the invention

The applicant after the search ignores the current existence of a monitoring system for speed of an axis with linear displacement present characteristics similar to those described herein memory.

Description of the invention

The system consists of a control panel which manages the movement of a sensor element that accompanies the shaft element of the application equipment being able to in any moment to know the position of the pump shaft and therefore the position of the pump itself and being able to control the times that it takes in each displacement in normal operation and discriminating the times of an abnormal displacement, managing thus the fault alarms and also being able to adjust electronically the pump limit switches simply by feeling some of the moving parts of the process to be controlled.

The system can be attached to any alternative oscillation with rectilinear displacement with a margin fixed speed under normal conditions and other margin of speeds in abnormal conditions, which can be arranged of a supportive surface integral to the axis in motion and power thus control the point where the axis is inside the total displacement

The system control electronics are composed of an automaton accompanied by different peripherals, to manage the entry of data or orders and to manage the outputs that will involve the activation of electro valves and other elements to Machine management.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is accompanied herein descriptive, as an integral part of it, a series of figures in which with an illustrative and non-limiting nature, has represented the following:

Figure 1.- Schematically represents a system of speed monitoring object of the present invention.

Preferred Embodiment of the Invention

The invention consists of two parts clearly differentiated, the measurement part (2) and the control part (1). The measurement part consists of a sensor, which is configured in the form of a probe, with the rod stretched at rest by means of a spring and accompanying the compression movement, with this component we will get a differential value, as it is in one or other end of total displacement. This value is necessary. for the entry of the management and control system. This part the form a control electronics (1) that manages the displacement of the sensor element (2), as well as the different machine operating modes, adapting the operation from this one to the selected mode and managing its stop and execution of alarm, if abnormal speed is detected, out of range predefined

The control part (1) is implemented in a waterproof box with an air supply inlet tablet (4) and a power input (5) for power the system, it also has a cable entry from the sensor element and several managed outputs electronically for process control. Control box (1) is provided with a main selector (6) that provides power supply to the components and in the selection part operating mode as supervision, it has several indicator lights (7) that indicate in a coded way the mode of current operation of the machine as well as the cause for which there has been an alarm and a light and acoustic warning that we indicates the occurrence of said alarm as well as the possibility of include a screen to visualize the characteristics of the problem, both its nature and a possible guide or steps to follow To carry out your solution.

The system detects the set of speeds that they leave the predefined range as normal, producing a stop, compressed air power cut (4) or power electrical (5), and a light and acoustic warning (7) indicating the occurrence of a failure and the reason for such failure.

The measuring element (2) is formed by a sensor element and a power system, with which get to be able to use the electronic control system (1) that By knowing the axis position at any time, you can manage both the axis travel speed at each moment and the possibility of positioning numerous points where you can invest the movement of the mechanism, and thus be able to perform movements of different cleaning or dosages with different pumps etc...

This system electronically regulates the positions and paths of the element to be controlled thus being able to select the range of displacement in each routine of operation and thus achieve adjustment, regulation, and even more precise behavior.

Once the nature of the present invention, as well as a practical application of the same, we only have to add that both its form and materials and execution thereof, are susceptible to modifications, as long as they do not substantially affect the characteristics claimed below.

Claims (1)

1. System for monitoring the speed of an axis with linear displacement, used in devices, devices and elements for the dosing and mixing of liquid products, characterized by being formed of two clearly differentiated parts, on the one hand the measuring element (2 ), which consists of a sensor configured in the form of a probe and on the other, the electronic control part (1) that collects the corresponding position signals from the sensor element and is responsible, depending on the pre-established programming of the electronic process management of the machine, with means to produce a stop, cut of compressed air supply (4) or electrical supply (5), and a light and acoustic warning (7) indicating the occurrence of a fault and the reason for such failure and , in the same way with options to act on the speed of movement of the axis in each moment as the possibility of positioning numerous points where to be able to reverse the movement of the m mechanism, and electronically regulate the positions and paths of the element to be controlled and can thus select the range of displacement.
