Abstract

A DEVICE FOR CONTROL AND SORTING DETAILS, comprising a housing, an inlet nozzle, a caliber, an outlet nozzle and a feed nozzle encompassing the outlet nozzle and forming an ejector with it, characterized by the fact that, in order to increase reliability, the cavity between the inlet nozzle and caliber communicated peripheral channels with the ejector.

Description

FIG. 1 The invention relates to a measurement technique and can be used to control and sort small items. A device for monitoring and sorting parts according to linear dimensions is known, comprising a housing, an inlet nozzle, a caliber, an outlet nozzle and a nozzle, a discharge nozzle, which forms an ejector with it, successively along a common axis. 6, using an ejector, the monitored product is sucked into the caliber. Some products go through a caliber, and some do not, which ensures the sorting of parts according to the cross-sectional diameter. With a diameter of less than 0.5 mm, the force of retraction of the part into the caliber is insignificant, which leads to incomplete sorting of parts. The purpose of the invention is to increase the reliability of control and sorting of parts. This circuit is achieved by the fact that in the device dp control and sorting of parts, comprising a housing, an inlet nozzle, a caliber, an outlet nozzle and a feed nozzle that surrounds the outlet nozzle and forming an ejector with it, a cavity between the inlet nozzle and the caliper communicated by peripheral channels with an ejector. Fig, 1 shows the described device at the position of issuing suitable parts; in fig. 2 - device on the position of tight parts; in fig. 3 shows a section A-A in FIG. The device contains a loading tray 1, a safety device 2 years of detail, a safety device 3 taut parts, a housing 4 located in the housing successively along a common axis: an entrance nozzle 5, a caliber 6, an output nozzle 7, a feeding nozzle 8 that surrounds the output nozzle 7 and In this case, an ejector, sensors 9 and 10, a flap 11. A cavity 12 between the inlet nozzle 5 and caliber 6 is connected by peripheral channels 13 and openings 14 in the output nozzle 7 with an ejection section b of the ejector. The nozzle 8 is reported by channel 15 with a source of compressed air (not shown). The device works as follows. In the initial position, the housing 4 is located soo.no boot tray 1, the sensor 9 and the safety device 2 usable parts. The channel 15 is continuously supplied with compressed air, and through the loading chute 1, controlled parts 16 are supplied, which are bundles of several wires. At the same time, a vacuum is created in zone B, which ensures the flow of air into the nozzle 7 both through gauge 6 and through the peripheral channels 13 and openings 14. The air flow entering the nozzle 7 carries with it the next controlled part 16 and draws it to caliber 6. At the moment of arrival of the part at the entrance of the caliber, two forces act on it, tending to draw the part into the caliber: the pressure difference on the Topi and the force of friction on the side surface. By adjusting the air flow through the feed nozzle 8 and the orifice 14, the required force is drawn in to draw the monitored part into the caliber 6. If the part 16 is suitable, then it passes through the caliber 6 and moves to the safety device 2 suitable parts. The sensor 9 after the passage through it of parts 16 gives permission to feed through tray 1 of the next part. If the part 16 is tight, then it does not pass into the hole of the caliber 6 and remains pressed by the air flow to it. Sensor 9, without fixing the passage of the part 16, gives a command to move the body 4 to the safety device 3 taut parts, where the valve 11 is triggered by skipping the opening of the nozzle 8. Compressed air supplied through the channel 15, acting in the opposite direction, passes through the output nozzle 7, holes 14 and the inlet nozzle 5., throws tight parts 16 through the sensor 10 in the safety device 3 tight parts. Then, at the command of the sensor 10, the flap 11 is retracted, the housing 4 is moved to the loading chute 1 and the cycle is repeated. Introducing the peripheral connection of the cavity between the inlet nozzle and the caliber with the ejector allows to increase the force that pulls the controlled parts into the caliber and, consequently, to increase the reliability of control and sorting of the parts.
