Description

Two scale list table electronic counting scales

The utility model relates to the two scale structures of a kind of size, two scale by counting meter 3 unified managements of weighing, two scale collaborative work, not only can weigh but also isarithmic pair of scale list table electronic counting scale.It can be widely used in the various industries that need count a large amount of standard components.

Existing electronic counting scale is to adopt single scale list instrument structure, can not take a sample automatically, example weight need carry out manual input by keyboard, so just need carry out weighing in advance to sample with the higher scale of another precision, in the manual input process of example weight, exist the deficiency of transmission error, thereby error is introduced final counting.Though some electronic counting scale can be taken a sample automatically at present, still adopts single scale list instrument structure.The range of singly weighing, if when the counting of big range of weighing and little range of weighing article required to take into account simultaneously, implementing then relatively, difficulty maybe can't realize.

The purpose of this utility model is a kind of pair of scale list table electronic counting scale of developing at above problem, it is to adopt two scale list instrument wheeled constructions, the two scales of size carry out unified management by the same counting meter 3 of weighing, have three kinds of counting modes: the promptly for a short time little scale counting of sample that weighs, for a short time weigh sample large scale counting, large scale sampling large scale counting.Have two kinds of ranges of weighing simultaneously: promptly little scale is weighed, and large scale is weighed.So can take into account the counting of big range of weighing and little range of weighing article simultaneously.It has automatic sampled functions, and sampling mode is: by weighing the weighed average of some samples of dose known amounts as single sample weight of sampling table top, i.e. digit's weight.The two scales of size all adopt resistance strain weighing transducer.In addition, this pair scale list table electronic counting scale also has the counting printing, removes packing tare weight and real time clock function.

The utility model is achieved in that two scale list table electronic counting scales comprise little scale, large scale and the counting meter 3 of weighing, wherein, little scale is to be made of little scale weighing platform 1, little scale LOAD CELLS 2 and the counting meter 3 of weighing, large scale is to be made of large scale weighing platform 5, large scale LOAD CELLS 6, large scale chassis 7, BOGEY WHEEL 8 and the counting meter 3 of weighing: little scale weighing platform 1 is housed on the counting meter 3 of weighing, and little scale LOAD CELLS 2 is contained in the counting meter 3 of weighing; Large scale chassis 7 is housed on the BOGEY WHEEL 8, and large scale LOAD CELLS 6 is installed on the large scale chassis 7, and large scale weighing platform 5 is housed on large scale LOAD CELLS 6; The counting meter 3 of weighing connects little scale LOAD CELLS 2 and large scale LOAD CELLS 6 by control line.

Good effect of the present utility model is:

1. this product adopts two scale list instrument wheeled constructions, manages the two scales of size with the counting meter 3 of weighing, and the general high little scale of resolution that adopts of sampling is realized sampling automatically, has reduced the transmission error of manual input example weight.The two scale collaborative works of size, with three kinds of counting modes of software control and two kinds of ranges of weighing, enumeration problem when having solved on a large scale to article and among a small circle.

2. the LOAD CELLS of this product is to adopt resistance strain weighing transducer, and the counting reaction velocity of weighing is fast.Adopt the algorithm of optimizing, the poidometer logarithmic data is short stabilization time.Simplify user's operation simultaneously, improved accuracy and work efficiency that the user measures operation.

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, 2.The scale structure of two scale list table electronic counting scales has following characteristics, two scale list table electronic counting scales comprise little scale weighing platform 1, little scale LOAD CELLS 2, the counting meter 3 of weighing, large scale weighing platform 5, large scale LOAD CELLS 6, large scale chassis 7, major parts such as BOGEY WHEEL 8, wherein by little scale weighing platform 1, the little scale LOAD CELLS 2 and the counting meter 3 of weighing constitute little scale, by large scale weighing platform 5, large scale LOAD CELLS 6, large scale chassis 7, the BOGEY WHEEL 8 and the counting meter 3 of weighing constitute large scale, form two scale list instrument wheeled constructions by little scale and large scale and the counting meter 3 of weighing, the two scales of size are managed collaborative work by the same counting meter 3 of weighing.Its medium and small scale and the counting meter 3 of weighing are fitted together, and little scale connects with adopting column 4 being connected of large scale, or adopt cable 9 to connect.The weigh scale of scope of little range is the type of attachment (as shown in Figure 1) that adopts column 4; The weigh scale of scope of wide range is the type of attachment (as shown in Figure 2) that adopts cable 9.

The move mode of large scale is a wheeled construction, has mobile flexible characteristic.

Shown in Fig. 3,4.The output of little scale LOAD CELLS 2 is passed through the processing of microcontroller 11 again through the conversion of analog-to-digital conversion module 10, forms example weight data or counter weight data.The output of large scale LOAD CELLS 6 is passed through the processing of microcontroller 11 again through the conversion of analog-to-digital conversion module 10, also forms example weight data or counter weight data.The sampling determined by keyboard 14 according to the operator of microcontroller 11 and the little scale or the large scale of counting usefulness then, count calculation process according to certain algorithm, counting and weight result send display module 15 to show, perhaps send print module 12 to print, the date and time during printing is taken from real time clock 16.Counting and weight data also can mail to host computer by serial port module 13 and manage.The operator can finish various metrological operations by keyboard 14.
