Description

The invention relates to the field of instrumentation for measuring the mass of bodies, in particular m co-products, and can be used in workshops (plants) and cattle slaughter and processing centers, industrial refrigerators, sausage and canning shops (factories), packaging compartments, expeditions and warehouses, in enterprises of the meat industry, when weighing meat carcasses and half-carcasses on a monorail scale, hanging buckets with minced meat, frames with sausage products and other meat products.

with an electronic computing machine, each automated weighing station contains a monorail scale with a dial quadrant pointer, a weighing machine panel having a built-in programmable controller with a parallel input-output device associated with a built-in programmable controller, a small-sized printing device, a conveyor drive and a collector for supply and removal of cargo from the weight monorail, consisting of twin pushers on a common carriage with a drive, a load passage sensor, svz data with a load passing along the weight monorail, a load mounting sensor on the weight monorail, and a pair of pushers initial position sensor, inputs connected to the coupled pushers 2,

The disadvantage of the prototype is the use in a monorail scale of a dial quadrant of 1 ha, but with remote registration of the UCCD. The most critical node in the UCDF index is a set of code disks consisting of four code disks and one fixing disks. A set of code disks requires high precision manufacturing and assembly. The interrogation of the code disks is carried out sequentially, and during operation there is a malfunction and mass registration. As a result of the locking disc being firmly connected to the linkage system during weighing, breakdowns occur when the load acts on the linkage system. Managing a picker feeding a given number of carcases or half carcasses to a weight monorail is carried out manually.

These disadvantages reduce the performance of the known co-product weighing system.

It is an object of the invention to increase the productivity of a spout during weighing.

This goal is achieved by the fact that the dial quadrant pointer is made with an optical transducer in the form of pairs of emitters and receivers, the number of which is equal to the bit representation of the mass in binary parallel code and is installed on the arrow axis of the pointer between the emitters and receivers of the code disk with alternating frequency and transparency - mi and opaque sections, while the outputs of the receivers of the optical converter are connected to the first inputs of the device of parallel input-output programmable control The range, the outputs of the sensors for the passage of cargo, the installation of the load on the weight monorail and the initial position of the paired pushers are connected respectively to the second, third and fourth inputs of the parallel input-output device, the fifth, sixth and seventh outputs of which are connected respectively to the inputs of the coupled pusher drive and feed drive conveyor belt.

Dial quadrant pointer

9 equipped with an optical converter

10 masses in binary parallel code (hereinafter cyclic code).

The optical converter shown in FIG. 5, contains optocouplers and a code disk 40. Optocouplers with an open optical channel were prepared by photodiodes 41 and LEDs 42, separated by an air gap in which the code disk rotates.

The photodiodes 41 and the LEDs 42 are mounted in the sockets of the shoe 43 coaxially, strictly opposite each other. The number of optocouplers is equal to the resolution of the digital representation of mass.

The code disk is designed to modulate the light fluxes coming from the LEDs 42 (emitters) in accordance with the code mask to the photodiodes 41 (receivers). The code disk (Fig. B) is made of organic glass with the code tracks with transparent and opaque portions deposited on it in a photoway, In FIG. 6 transparent portions (segments) of the code disk are obscured. The code mask of the tracks is made in a cyclic code.

The code disk is mounted on the hub 44 (Fig. 5), the hub with the code disk, in turn, on the axis 5 of the arrow and fastens to the nuts 46. The gap between the code i disk, photodiodes and LEDs should be the same, which is achieved by moving the code disk axially with bearings 47. Gear 48 engages with. toothed rack of a dial quadrant pointer.

In FIG. 7 (sheets 1-4) shows a scan of a code disk in accordance with bits of a cyclic code.

The 4Q transistor is designed to amplify the signal from the photodiode 41. The Schmitt trigger is used to convert the waveform to digital. The resistors are intended: a resistor 51 for limiting the current in the circuit of the LED 42, a resistor 52 for creating a bias on the basis of the transistor 49, and a resistor 53 for limiting the collector current of the transistor 49.

A weigher console 54 with an integrated programmable controller is shown in FIG. 9. The structurally programmable controller consists of a board (not shown in FIG. 9), a display 14, and a keyboard unit 15. In addition, on the weighing console there is a placard of 19 details.

In FIG. 12 shows a display of 19 details with LEDs 20 for an automated weighing facility for pork carcasses in the slaughterhouse and cutting cattle when transferring the carcasses to the refrigerator. In relation to this weighing point, the following conditionally constant details are used that characterize the batch of pigs as a whole (bits):

operating mode (input B or dose D) -1 code of the weigher (personnel number) - 4

date - 6

gurt number - 6

view m sa - 3

shelf life - 1

The following are used as variable attributes characterizing each weighed carcass (bits):

carcass weight - 4

code m sa - 4

number of clips - 1

purpose (direction of use) - 1

The codes of the functioning of the automated weighing station in the absolute boot format and all the reference information are stored in a read-only memory (ROM) of the programmable controller.

When building reference books-classifiers of meat raw materials, classification is used according to the following criteria:

type of meat (101 dykes, 102 pork, 103 - lamb, 104 - horse meat, 109 - wild cattle);

shelf life (0 - suitable m s. 1 - conditionally suitable m s);

meat code (for example, for pork without skin: 0083 - 2 categories; 0084 - 3 categories; 0085 - 4 categories and 0087 - non-standard categories);

purpose (2 - implementation, 5 - industrial development).

In order to determine the average mass of the roller at the milling plant, commissions are created led by the chief engineer; The Commission weighs the rollers on a scale with a division price of 0.5 kg by weighing three batches of rollers, ten pieces each.

For example, if as a result of control weighings it is established that:

upon first weighing ten rollers weighing 33.00 kg;

at the second weighing, ten rollers weighed 32.95 kg;

at the third weighing, ten rollers weighing 32.95 kg,

then the average weight of one roller is 3.297 kg.

After installing a set of technical means for measuring mass at the place of operation, it is necessary to carry out verification, which includes the following operations: external inspection, testing and determination of metrological characteristics.

The total basic error of the Ac weighing system, for example, meat carcasses for each automated weighing station, is estimated by the standard deviation

Ar + A ™ + A Rps + MBM (1)

where Duck op - the main error of the pointer of the dial quadrant with an optical converter;

AIC - the main error of the programmable controller;

LPS is the basic error of the radial serial communication interface (this link does not participate in the conversion of the measured value, therefore this error is zero and does not make any changes to the system);

Devm - the basic error of the electronic computer.

When certifying the communication channel of each automated weighing station with a computer, the reliability of the data transmission is the probability of distortion of the P bit with the adopted method of monitoring by echo signals and retransmission of each transmitted symbol.

If we assume that the probability of distortion of the values 0 and 1 is the same and equal to P, then the number of binary bits C, which can be accurately transmitted over the channel, is:

0

5

0

5

0

5

C is 2F 1 + Plog2 (P) + (1-P) log2 (1-P), (2) where F is the channel bandwidth.

If a message with a length of I bits is transmitted over the channel, then the average number of errors a will be equal to

a-l "P (3)

Verification of the functioning of the complex technical means of the weighing system is carried out using the following tests:

-programmable controller;

-weights with a pointer and an optical converter;

- small-sized printing device;

- the details board;

-IRPS (radial serial communication interface).

The metrological characteristics of the weighing system are determined in the following sequence:

- inconsistency of readings of unloaded scales;

- sensitivity of scales;

-independence of indications on the position of the load;

- basic error;

-variations of the readings of loaded weights.

The principle of operation of the weighing system is as follows. After switching on the weighing system, all technical means are initialized. Then, from the keyboard block 15, the number of loads simultaneously supplied to the weight monorail 6 is set (for example, two pork carcasses or one MPC carcass), and control is transferred to the picker driver, as a result of which the signal appears at the output of the programmable controller parallel I / O device 13 The start of the feed cover, generated by the electronic key, this signal being fed to the input of the drive of the feed conveyor. A similar electronic key is controlled by a picker.

The signal from the cargo passage sensor 23 is input to the device 13, from where it is read into the internal register of the central processor of the programmable controller. Similarly, the signals of sensors 24 and 25 are read.

Next, the system goes into interactive mode with the weigher, who enters the corresponding props code from block 15 of the keyboard. The input information is written to the RAM of the programmable controller. After entering the details relating to the entire batch of livestock, information in asynchronous mode is transferred to the buffer of a small-sized printing device 16 and printed on a narrow tape of this device.

At the end of the communication session with the small-sized printing device 16, a transfer to the next weighing takes place.

Information about the mass of the load is generated by an optical converter, the operation of which is based on the principle of cyclic code conversion, and the mask is applied to the code disk into digital signals using ten optocouplers. The signals from the photodiodes 41 are fed to the bases of transistors 49, amplified, and fed to the inputs of Schmitt triggers 50 to convert the waveform to digital. The signals amplified and processed in this way are sent to the inputs of the device 13 of the parallel input-output of the programmable controller and then to the central processor 35, where they are processed by the driver of the weighing device (by the weighing device we mean monorail scales with a dial quadrant pointer with an optical converter) .

The driver of the weighing device provides automatic processing of information from the optical converter, as well as loading

and unloading the weighing device. The mass data at the output of the optical converter is presented in an 11-bit cyclic code, which ensures high reliability of the transmitted information.

When loading the load-receiving unit of the weighing device, a digital code appears at the output of the optical converter, which varies as a first approximation according to the following law:

NBb, x. (T) N0 + Na sln (2 log | + p) e (4)

where Mvykh.M is a digital code corresponding to the instantaneous measured value of the mass at time t;

No is a digital code corresponding to the established mass value;

Na is the amplitude of free vibrations of the loaded weight measuring device;

T is the period of free oscillations of the loaded weighing device; (initial phase of oscillations; b - logarithmic decrement of damping of oscillations, depending on the degree of damping of the moving system of the weighing device.

An experimental study of the weighing device made it possible to determine the specific numerical values of the following parameters:

T-1.2-1.5 s;

Na / N0 0.1 -0.2

t / T 1 - 4

Thus, the criterion for calming the weighing device is the fluctuation of the digital code at the output of the optical transducer within the low-order unit.

Consider the structure of the weighting algorithm. The algorithm is based on the determination of the extrema of the NBbix. (T) function by the following criteria:

N (ti) N (tH-i)

- max (5)

N (ti) N (ti-i) J N (t,) N (ti + i)

C - mln, (6)

N (ti) N (ti-i) J

where ti-i; ti; ti + i successive moments of measurements, and

At (trti-i) (tn-i-ii) - (0.16-0.2) T 0.25 s. Such a discrete interval provides, on the one hand, measurement without loss of individual extrema due to the high measurement frequency, and, on the other hand, eliminates the detection of false extrema due to the fact that the discrete interval significantly exceeds the fixation time of the digital code at the output of the optical converter and the cyclic conversion code in direct digital code.

Calming criteria are written as follows:

| N (ti) -N (tHi) I

IN (ti) -N (ti-i) (7)

either N (ti-i) N (T) N (ti + i))

; N (t,) N,) (8)

If condition (8) is satisfied, the weighing process immediately ends and (ti). This is a special case of condition (7) and most often the fulfillment of condition (8) is possible with a weight of weighed loads of up to 100 kg and strong damping of the system. At the same time, the time required to determine the fact of calm is at least 0.25 s after the fluctuations enter the tolerance limits according to condition (7).

When condition (7) is fulfilled, it is necessary to make a fixed number of measurements and determine the mathematical expectation of the value of M0 by the formula:

M (N0) J Noi / n,

I 1

ABOUT)

where n is the number of measurements required for averaging;

Noi is the digital code at the output of the optical converter.

Thus, the total weighing time will be:

tB ti + 1 under condition (7);

tB tj + 0.25 under condition (8).

If condition (7) was violated during averaging, for example, due to a sharp blow to the cargo being weighed, then the weighing process starts again.

Upon completion of the weighing process, the system enters into a dialogue mode of communication with the weigher. Details are entered for the plumb line. The procedure for entering details is carried out similarly to the foregoing. The programmable controller proceeds to a communication session with the small-sized printing apparatus 16.

Having finished printing the data on a plumb line, the system goes into the interactive mode of working with a weigher. If the weigher does not enter a sign of the end of the batch and the number of plumb lines is less than 100, then the next weighing proceeds. Otherwise, the programmable controller proceeds to summarize the weighing results and forms an output information array.

After that, the programmable controller 5 proceeds to a communication session with a small-sized printing device,

printing batch weighing results

cattle as described above.

Upon completion of printing on a small-sized printing device, the programmable controller proceeds with the communication procedure with the central electronic upper-level computer, during which the programmable controller transmits in asynchronous mode. output information array retrieved from RAM.

During a communication session,

0 detection and correction of distorted information using echo control and retransmission. This array is used for the needs of the upper level of the system.

5 During operation, at each automated weighing station, a livestock weighing protocol is generated on a narrow ribbon of a small-sized printing device. In the table. 1 is given

0 fragment of weighing protocol for pork carcasses at an automated weighing station.

Upon completion of the weighing protocol, all batch information

5 livestock are provided in a communication channel with a central upper level computing machine. The information transmitted in this way is processed at a higher level and is used to print plumb bills.

In the table. Figure 2 shows a plumb bill received on a central electronic computer from an automated weighing center for pork carcasses. This

5, the plumb bill corresponds to the batch of cattle (pigs) printed in the weighing protocol (Table 1).

Evaluation of the weighing system of meat carcasses at such hot points of carcasses of cattle, pigs and small cattle in the slaughterhouse and cutting of cattle when calculating with livestock suppliers allows an objective analysis of the advantages of the invention in comparison with the prototype based on specific experimental data.

Using an optical mass-to-cyclic code converter reduces the weighing time by half, and reading the weight t of the load is carried out immediately after the balance arrow is calmed down. The design of the converter is simplified compared to the prototype, while instead of five disks, one code disk with alternating optically transparent and opaque areas excluded from the design of the engine. The alignment of the optical converter is simplified; the adjustment can be carried out without an additional typewriter using cyclic code check tables. The cleaning of dusty elements in the optical converter (disk, diaphragm) is greatly simplified in comparison with the UCD indicator.

An automatic picker containing twin drive pushers and three sensors feeds two half-cattle and pigs or one MPC carcass from the feed conveyor to the weight monorail and removes them from the weight monorail to the discharge conveyor of the refrigerator using programmable controller software. When using control from a programmable controller, the order of feeding two half carcasses or one carcass to the weight monorail is not violated, the correct recording of each plumb line in plumb lines is observed, and the performance of weighing meat carcasses is increased.

Due to the synchronization of the operation of the feed conveyor, picker, weighing device with an optical converter and a programmable controller, the possibility of overfilling with carcasses or half-carcasses of the branding and accumulation section is excluded, this prevents the rollers from crawling on top of each other, jamming and dropping of carcasses or half-carcasses with rollers from the weight monorail.

Thus, the use of the co-product weighing system as a whole makes it possible to increase productivity when weighing co-products and when generating reporting documents, to simplify the maintenance of automated weighing points, and to increase the reliability of the system.
