Description

The invention relates to transport and can be used to account for loaded mobile objects, for example, in mines and mines. A device for automatically counting loaded moving objects is known, comprising a weight sensor, a load determining unit, a pulse counter, a time relay and a counting 1. It is also known a device for automatically counting loaded moving objects, for example trolleys, containing a weight sensor, blocks for determining the loading level of moving objects and the block of the presence of a loaded moving object, connected to the counter of the moving objects loaded 2. However, the devices do not provide reliable information about the number honors loaded at the loading point of moving objects. The purpose of the invention is to increase the accuracy of the control of the loaded moving objects at this loading point. The goal is achieved by the fact that the device is equipped with a unit for the absence of a moving object in the loading area and a control unit for a partially loaded moving object, with the first, second and third weight sensors connected, respectively, to the first, second and third blocks of the loading level of moving objects, first outputs which are connected, respectively, to the first, second and third inputs of the block of the absence of a moving object in the loading area, connected by an output to one of the inputs of the control block of a partially loaded subs object, the other inputs of which are connected respectively to the other and third outputs of the first, second and third blocks of the loading level of moving objects, the fourth outputs of which are connected, respectively, to the first, second and third block inputs of the presence of a loaded mobile object connected by other inputs to the output of the block control of a partially loaded moving object and with one of the outputs of the second block of the loading level, and the other output with a block of the absence of a moving object and with a control block of partially Fishing movable object. The drawing shows a functional block diagram of the device.

The device contains sensors 1, 2 and 3 weights connected, respectively, to the first 4, second 5 and third 6 blocks for determining the loading level of moving objects, unit 7 for the absence of a moving object (trolley) in the loading area, connected to the first input of control unit 8 partially loaded mobile object in the loading area, block 9 of the presence of a loaded mobile object connected to the counter 10 mobile objects.

The first outputs of blocks 4, 5 and 6 are connected to the first, second and third inputs of block 7, the absence of a moving object in the loading area. The second and third inputs of block 8 are connected to the second and third outputs of the first block 4 loading level of moving objects, and the fourth input of block 8 is connected to the second output of the second block 5, the third output of which is connected to the fifth input of block 8, the sixth and seventh inputs of which Zana with the second and third outputs of the third block 6, and the fourth outputs of blocks 4, 5 and 6 - with the first, second and third inputs of block 9, respectively, the fourth input of which is connected to the output of block 8.

The device works as follows.

The level of loading of mobile objects, such as a trolley, is determined by mineral resources using weight sensors 1, 2 and 3, which convert the weight load into an electrical signal.

The signals from the sensors 1, 2 and 3 of the weight vary in accordance with the change in the force applied to them, and are fed to the corresponding inputs of the first 4, second 5 and third 6 blocks of the loading level of moving objects having four outputs. As these blocks, threshold elements are used that react to a certain signal level, i.e., if the input signal reaches the value, then a signal E appears at the first output, with an input signal equal to Isrg at the second output, the signal EI and so on. d. The peculiarity of operation of blocks 4, 5 and 6 of the loading level of moving objects is that the signals on some of their outputs are absent when there are signals on the corresponding others.

The first outputs of blocks 4, 5 and 6 of the loading level of moving objects correspond to the absence of a trolley (empty or loaded) at the loading point, the second to the presence of an empty trolley, third to the absence of the required load in the trolley (the weight of the load in the trolley is equal to a certain number but less than the required weight ) and the fourth - the presence of the required (valid) weight of the mineral in the trolley.

In the absence of a trolley (empty or loaded) at the loading point, to the inputs of block 7 there is no mobile object in the loading area from the first exits

The units 4, 5 and 6 of the loading level of the moving objects receive signals. As a result, at the output of the block 7, there is no moving object in the loading area, a signal arrives at the first input of the control unit 8 of the partially loaded moving object. The first outputs of blocks 4, 5 and 6 are used to control the absence of a moving object (loaded or empty) in the load zone, which indicates that the weight sensors 1, 2 and 3 are operational.

The absence of one of the signals from the first

the outputs of blocks 4, 5 and 6 of the loading level of moving objects do not allow an incorrect account of the loaded objects, since the output of block 7 will not

signal.

The process of starting the loading of mobile objects (at the loading point of a partially loaded trolley) is recorded using signals from the second and third outputs of blocks 4, 5 and 6

0 loads of moving objects, to the corresponding inputs of block 8. When moving a moving object from left to right, signals from the second and third outputs of the first 4 and second 5 blocks of the loading level of moving objects arrive at the corresponding inputs of block 8. A signal appears at the output of this block arriving at the fourth input of block 9. When the trolley moves from right to left, signals from the second and third outputs of the second 5 and third 6

O blocks of the loading level of moving objects arrive at the corresponding inputs of block 8, and at the output a signal appears about the loading of the trolley at this loading point.

When the loaded trolley moves from left to right (the trolley's wheelsets are on 1 and 2 weight sensors, when a certain amount of cargo reaches the trolley during its loading, a signal arriving at the second mobile unit appears at the fourth exit of the second block 5 the entrance of the block 9 of the presence of a loaded moving object. Then the trolley is placed in the next position in the direction of movement relative to the loading point (the wheel pairs of the trolley are located on 2 and 3 weight sensors). Trolley and installation of the first wheelset on the weight sensor 3, the signal at the second input disappears and appears at the third input of block 9. After loading the trolley to the valid weight, the fourth output of the second block 5 of the loading level of moving objects receives a signal at the second input of block 9 The presence of signals at the second and third inputs of block 9 indicates that the trolley was loaded when moving from left to right. Since at this time there is a signal at the fourth input of block 9, one is added to the meter 10 for accounting of loaded moving objects. Accounting for loaded objects when moving from right to left is done in the same way as described above, and the unit is recorded in counter 10 when there are signals on the first, second and fourth inputs of block 9 of the presence of a loaded trolley.

When a loaded moving object leaves the loading point (moving from left to right), the signals at the fifth and third inputs of block 9 coincide, and at its second exit, a signal appears that sets block 7 and block 8 to the initial state. The device is ready to take into account the following moving objects loaded at this loading point.

When a loaded moving object passes through a loading point, there is no signal from the second output of block 5 of the loading level of moving objects, therefore, there will be no signal at the output of block 8 and writing to counter 10 will not occur.
