Abstract
The utility model discloses a weighing mechanism with automatic fault detection; the weighting mechanism comprises weighting sensors and suspension rods; the weighting sensors comprise a weighting sensor A and a weighting sensor B connected by a pull rod; the top of the weighting sensor A and the bottom of the weighting sensor B are respectively provided with the suspension rods; the weighting sensor A is connected with a weighting support through the suspension rod; the weighting sensor B is connected with a weight thing carrier through the suspension rod. When the weighting sensor is damaged and the damage cannot be timely detected, metering accuracy is reduced, and production quality is affected; the weighing mechanism with automatic fault detection solves the said problems, realizes automatic detection of weighting sensor faults, so the faults of the weighting sensor can be timely found, thereby ensuring metering accuracy of the weighting sensor.
Description
Technical field
The utility model relates to a kind of Weighing mechanism, particularly a kind of Weighing mechanism with automatic fault detection.
Background technology
LOAD CELLS is a kind of original paper for calculating the weight.In metering process, sensor passes through to change self bulk properties parameter, and characterisitic parameter is transferred to control system, and then control system calculates weigh according to output parameter value, thereby reaches the object of weight metering.
During use, LOAD CELLS is arranged on and is weighed above carrier by certain mounting means.Common the used Weighing mechanism LOAD CELLS of same stress point installation that adopt are measured more at present, arranging in the time of can causing LOAD CELLS to damage of the structure of this single LOAD CELLS cannot be found timely and effectively, this situation generally can only rely on the quality of operating personnel's micro-judgment LOAD CELLS, have a strong impact on the accuracy that LOAD CELLS is measured, brought inconvenience to people's normal use.
Summary of the invention
The technical matters that the utility model solves has been to provide a kind of Weighing mechanism that automatic fault detects that has, and mainly solves when sensor damages and can not find in time, causes metering accuracy to reduce, and affects the problem of the quality of production.
For solving the problems of the technologies described above, a kind of Weighing mechanism with automatic fault detection of the utility model, it is characterized in that, comprise LOAD CELLS and suspension rod, described LOAD CELLS comprises LOAD CELLS A and LOAD CELLS B, between LOAD CELLS A and LOAD CELLS B, by pull bar, connect, the lower end of the upper end of described LOAD CELLS A and LOAD CELLS B is respectively arranged with suspension rod, described LOAD CELLS A is connected in weighing bracket by suspension rod, and described LOAD CELLS B is connected in by suspension rod the thing carrier of weighing.
The connecting portion of described pull bar and LOAD CELLS A and LOAD CELLS B arranges respectively clamp nut.
The connecting portion of described weighing bracket and suspension rod arranges packing ring and clamp nut, and described packing ring is two, and two packing rings are respectively spheric washer and taper faced washer.
The beneficial effects of the utility model are: a kind of Weighing mechanism with automatic fault detection of the utility model has overcome current the used indiscoverable deficiency of LOAD CELLS fault, realized the automatic detection of LOAD CELLS fault, be convenient to find in time the fault of LOAD CELLS, keep in repair timely, guaranteed the normal use of LOAD CELLS.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
In figure: 1-LOAD CELLS, 11-LOAD CELLS A, 12-LOAD CELLS B, 2-pull bar, 3-suspension rod, 4-weighing bracket, the 5-thing carrier of weighing, 6-clamp nut, 7-packing ring, 71-spheric washer, 72-taper faced washer.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in Figure 1, a kind of Weighing mechanism with automatic fault detection of the utility model, it comprises LOAD CELLS 1, described LOAD CELLS comprises LOAD CELLS A11 and LOAD CELLS B12, between LOAD CELLS A11 and LOAD CELLS B12, by pull bar 2, connect, the lower end of the upper end of described LOAD CELLS A11 and LOAD CELLS B12 is respectively arranged with suspension rod 3, described LOAD CELLS A11 is connected in weighing bracket 4 by suspension rod 3, and LOAD CELLS B12 is connected in by suspension rod 3 the thing carrier 5 of weighing.
At pull bar 2 and the connecting portion of LOAD CELLS A11 and LOAD CELLS B12, clamp nut 6 is set respectively.Arrange like this and can prevent that on the one hand between pull bar 2 and LOAD CELLS, generation is loosening, thereby affect the measuring accuracy of LOAD CELLS; When one of them LOAD CELLS breaks down, be convenient to change on the other hand maintenance, the replacing maintenance of one of them can not affect another normal use yet.
Described weighing bracket 4 arranges packing ring 7 and clamp nut 6 with suspension rod 3 connecting portions, and described packing ring 7 is two, and two packing rings 7 are respectively spheric washer 71 and taper faced washer 72.The packing ring that adopts spheric washer 71 and taper faced washer 72 to match, can reduce the impact for measuring accuracy of rocking of suspension rod.
During use, the signal of two LOAD CELLS 1 is all transported to Control System of Microcomputer, at inner two signals of Control System of Microcomputer, control weight parameter contrast, if reduced parameter surpasses the value range of setting, just prove that one of them sensor damages, by Control System of Microcomputer, send alerting signal, prompting staff carries out fault eliminating, has effectively avoided LOAD CELLS to break down for the impact of measurement result.
Except the technical characterictic described in instructions, be the known technology of those skilled in the art.
