The invention relates to a testing technique and can be used in the automatic control of hollow articles, mainly closed on one side of the tubes by the method of vacuum

An automatic device for monitoring the tightness of hollow products is known, which contains a feeder, a device for transporting products, made in the form of combs (driven and stationary), and a plate spread above them, a mechanism with a spring-loaded carriage and two clamping jaws for feeding products to the position of the Holter, a device for product sorting and pneumatic system with a leakage recorder Cl.

However, this device has insufficient performance, since it does not have a product flow divider and, therefore, Ke does not allow to combine technological and logical operations in time. In addition, the device does not provide orientation of the products when applying them to the control position, which reduces the reliability of its work.

The closest to the invention to the technical essence and the achieved result is an automatic machine for monitoring the tightness of hollow products, mainly tubes, containing test chambers with sealing elements, a pneumatic system with a leak recorder, a bunker feeder, a product flow distributor placed at its outlet, a product feed mechanism to the test chambers rotary damper sorting device associated with a leak recorder, control unit C2 3.

However, the known device is characterized by insufficient reliability due to the complexity of its design, which includes a flow distributor of drum-type products with a pulsed drive and a complicated pneumatic system with actuators for supplying

products in test chambers. I

The purpose of the invention is to increase reliability by simplifying the design.

The goal is achieved by the fact that in an automatic machine for monitoring the gemetry of hollow and buildings, mainly tubes containing test chambers with sealing elements, a pneumatic system with a leak recorder, a bunker feeder, a flow distributor placed at its outlet, a product feed mechanism into the test chambers, a sorting device with a rotary valve associated with the leak recorder, and a control unit, the code of the bumper feeder is divided into two channels equal to the population, the flow distributor It is complete in the form of a triangular prism installed at the branching point of the channels, which is rotatably fixed on the axis coinciding with its axis of symmetry, the spring intended

for fixing the prism in extreme positions with the support of the upper edge of the latter on one of the walls of the output of the feeder, and two parallel channels installed at the outlet of each channel

plates with electromagnetic drives for intercepting channels by the signal from the control unit, and the product feed mechanism is placed above the sorting device and is made in the form of rollers and cradles, movably mounted on the axes.

Figure 1 shows the machine, a general view; figure 2 - the node in figure 1; fig.Z - automatic, top view; on

4 is a test chamber; in fig. 5 is a view A of FIG. 3; Fig. 6 is a block diagram of a leak recorder.

The automatic machine for monitoring the tightness of hollow articles, mainly tubes, contains test chambers 1 with sealing elements 2, a pneumatic system (not shown) with a 3-leak detector, a Packer 4 feeder placed

at its outlet 5, a distributor b of the flow of articles 1, a mechanism 8 for feeding them into the test chambers 1, a sorting device 9 with a rotary valve 10 connected with the leakage recorder 3, and a control unit (not shown).

In the automatic machine, the output 5 of the bunker feeder is divided into two channels 11 equal in cross-section, the flow distributor 6 is designed as a triangular prism 12 installed in a place (not indicated) branching channels 11, which is rotatably fixed on the axis 13, the axis of symmetry coinciding with the axis 14, designed for fixing the prism 12 in the extreme positions with the support of the upper rib 15 last on one of the walls 16 of the outlet 5 of the feeder 4, and mounted on

output 17 of each channel 11 of two parallel plates 18 with electromagnetic drives 19 for alternately blocking the nanoli 11 according to a signal from the control unit. The feed mechanism 8 of the products 7 is placed above the sorting device 9 and is made in the form of rollers 20 and cradle 21 movably mounted on axles 22 and connected with a mechanical drive 23 by means of

T g 24 for dropping the passed, inspection of products 7 into the sorting device 9. In each channel 11, a sensor 25 is installed, which disconnects the conveyor 26, which supplies the product to the bunker feeder 4

The machine works as follows.

The tubular goods 7 to be monitored are placed on the conveyor 26 and are supplied with it; into the bunker feeder 4, the output 5 of which is branched "a two channels 11. With the help of the distributor b of the flow of the product 7 alternately fall into each of the two channels. This is ensured by the passage into the open channel 11, the product with its own weight turns the triangular prism 12 BOiKpyr of its axis 13, and the spring 14 fixes it in another extreme position, in which the edge 15 rests on the other wall 16 of the outlet 5 of the bunker feeder 4. With the help of The electromagnetic actuator 19, which alternately pushes the plates 18, opening the outlets 17 of the channels 11, is provided by piece delivery of products to the feed mechanism 8. The tubular product 7 on the mechanism 8 turns out to be a roller wheel 20, which ensures 10 tons. them in test kayira if where with the help of compaction-. Elements 2, compressing the product on the outer surface, create a volume from which air is pumped out using a pneumatic system, and the leakage recorder 3 records the degree of tightness of the products. If the product 7 is not hermetically sealed, a signal is sent to the shutters 10 of the sorting device 9. The product 7, passed control 5 in the test chamber 1, is removed from it by means of rollers 20 and pops onto the cradles 21, which are inclined, turning around the axes 22, at drive 23 and tg 24, and fall into the sorting device 9. In the case of filling the channels 11 with products 7, the sensors 25 emit a signal that stops the conveyor 26.

The use of the proposed isobra-5 retenie will simplify the design of the machine and increase its reliability.
