The invention relates to test equipment and can be used in automated testing for tightness of aerosol packages.

 The purpose of the invention is to increase productivity by increasing the frequency of the command signal and simplifying the design of the device. The drawing shows a diagram of the device.

The device for pushing the products from the position of the automaton contains pneumatic actuator 1, pneumatic amplifiers 2 and 3. The outputs 4 and 5 of which are respectively communicated with the cavity 6 of the forward stroke and the cavity 7 of the reverse stroke pneumo. cylinder 8 of pneumatic actuator 1, and inputs 9 and 10 with output channels 11 and 12 of the jet element OR-NOT Sh1I I3, which has inputs 14 and 15

Through atmospheric quiescent channels 25 and 26, pressure is relieved from pneumatic amplifiers 2 and 3.

The device works as follows

In the initial state, when the command signal at the input 14 of the jet element 13 is absent, the air flow Q in the jet element 13 flows out through the output channel NOT OR 12, the pneumatic amplifier 3 is in the amplification mode, and the supply pressure through the output 5 enters the cavity 7 is the reverse of the 5th stroke of the pneumatic cylinder 8, while the piston 18 is in the extreme right position. At the same time, in the pneumatic amplifier 2, the supply pressure is discharged into the atmosphere through the atmospheric rest channel 25. With the access-singing to the input 14 of the jet element 13 of the command signal, i.e. signal of the presence of a defect in the product 22, jet from the output channel 12 enumeration

on the output channel side, NOT W 12 12 25 is connected to the output channel OR 11, communicated respectively with the command signal line 16 and with the atmospheric channel 17 of the pneumatic amplifier 3, connected to the return cavity 7 of the pneumatic cylinder 8. Inside the pneumatic cylinder 8, the piston 18 moves with the rod 19 , on the end of which the pusher is attached is a pusher - a plate is concave

pneumatic amplifier 2 enters the amplification mode, and the supply pressure from outlet 4 enters cavity 6 of a forward stroke. The piston 18 begins to move off in the direction of the product 22, and the air displaced from the reverse travel cavity 7 from the atmospheric channel 17 enters the control input 15 of the jet element 13 Therefore, even after the end of the effect of the command signal (it can now be short on duration), the air jet in the jet element 13 will continue to exit through the exit

20 interacting at the end of the stroke of the rod 19 with the product 22 facing from the carousel 21. The output channel 11 is denied by the lumen channel and the output channel; 1l is NOT the lx 12. In the initial state, when there is no signal at the control inputs 14 and 15 The air stream expires through the output channel NOT OR 12. This state of the jet element OR NOT 13 due to its design features is stable. The device for generating a command signal for resetting from a car 21 or a device 22 is not shown, setting the command signal on line 16 is simulated by closing the pneumatic contact 23. By means of an adjustable throttle 24 a partial discharge of air into the atmosphere is performed. as the conductivity of the jet element 13 at control input 14 is limited, this has to be done. when the return air flow is displaced from cavity 7 (for example, with a large volume of cavity 7),

It is output to the output channel OR 11,

pneumatic amplifier 2 enters the amplification mode, and the supply pressure from output 4 enters the cavity 6 of the forward stroke. The piston 18 begins to move in the direction of the product 22, and the air displaced from the return cavity 7, from the atmospheric channel 17 enters the control input 15 of the jet element 13 Therefore even after the end of the command signal (it can now be short in duration) the air stream in the jet element 13 will continue to exit through the exit

channel 11 o This ensures a clear movement of the piston 18 as long as it is provided in the element 13 to hold the supply jet against the wall on the side of the channel SH 11, and

it will be as long as it is

piston is forced out of the reversal cavity 7 by the piston.

When it is removed by plate 20, product 22 finally encounters carriage 21 in a batch of rejected packages. After that, the movement of the piston 18 may still continue somewhat, but as soon as the flow of the displaced air from the cavity 7 is reduced to

quantities that are insufficient to hold the supply jet against the wall of the jet element 13 on the side of the suitable channel OR 11, the jet is transferred to the output NOT OR 12, and at the input 10

the power boost 3 appears pressure and the pneumatic boost 3 is in the amplification mode — from outlet 5 to the backflow cavity 7, pressure is applied, and porgeen 18 moves to the right to the initial extreme position, where it will be until the next command signal arrives. Even if several packs per second of several defective packs go one after the other in succession, the device manages to work, i.e. push them into a batch of defective packs. This is achieved precisely by eliminating the time for the command signal to pass through the second element of the command and return jet

signals, the formation of a return signal and its passage through the jet unit and the passage of a piston of an increased stroke Each of these components is small, but with high-performance control, they become noticeable. And they are one of the reserves for reducing the cycle time of the device. At the same time, an increase in the production of the device is accomplished by not complicating the connection of the return circuit with the cavity or changing the operating mode of the pneumatic cylinder.

elements, and simplification by reducing the number of elements and increasing reliability.
