Abstract

The invention relates to a foundry, in particular, to methods for producing a mold, controlling and automating this process. The purpose of the invention is to expand the functionality by providing traceability of the half-molds on a line having continuous conveyors. According to the invention, the order number of the half-form is counted and stored at the marking position, and the half-forms are calculated at the selected recognition position, the numbers obtained are compared and, if they match, the "labeled" half-form is identified. 2 Il.

Description

The invention relates to a foundry, in particular, to methods for producing a mold, controlling and automating this process.

The purpose of the invention is to enhance the functionality by providing traceable labeled half-molds on a line having continuous conveyors.

The control device diagram (Fig. 2) consists of a counter 7 half-forms at a memory position with a decoder 8. The decoder outputs are connected through the And 9 elements to the recording inputs of the register 10 memory cells. The outputs of the memory cells through the 11 elements are connected to the output element ISH1 12 devices. On the second inputs of the elements 11 are connected to the outputs of the decoder 13 of the counter 14 of the number of half-forms on the identification position. The number of elements 9 and 11 is determined by the number of register bits 10. A sensor is connected to input 15

2, to input 16 — a signal (for example, a button); Memory; to input 17 — a sensor 5.

The method and operation of the device are as follows.

Upon receipt of the half-form at position A, sensor 2 is triggered and counter 7 increases the content by one, i.e. actually records the serial number of the half-form. In this case, at the input of only one element 9, the signal of the decoder 8 appears. If it is necessary to memorize (mark) a given half-form, then press the button 4, and a unit is recorded in one of the bits of the register 10 of the memory. When semi-molds arrive at position B of the casting conveyor, sensor 5 is triggered, counter 14 records the serial number of the half-form. From one of the inputs of the decoder 13, the enabling signal is fed to the input of one of the elements 11. If information is recorded in the corresponding register bit, the element 11 is activated and its output signal is fed through the element 12 to the device output, i.e. authentication is done
