(54) VIBRATION CONVEYOR FOR FERROMAGNETIC

DETAILS

In the direction of the bowl of the bunker b of the vibrator 2. When the reference direction of the creeper 3 moves, at the same time it receives an upward movement and informs the movement 7 on it that it emits. The lower end of the spring 5 is fastened with a screw 8 to the base 1. The second end of the anchor rail 3 is attached to the bowl of the bunker b by means of a leaf spring 9 and screws 10 and studs with a helical rail 11 in zone 12.

The helical guide has a slope 12 in the direction of the center of the bowl of the bin 6 and a window 13 for orientation of the parts.

A magnet 14, controlled by the control means 15 according to a predetermined program, is installed above the additional direction. A sensor 16 is installed at the exit of the transport chute in the area 1 of the magnetic attraction of the permanent magnet 18. The sensor 16 is a contact wire electrically isolated from the device to which the constant voltage of the bw is connected. The control of the presence of the part 7 in zone 17 is carried out by closing the contact wire with the transported parts 7 to ground.

The second magnet 18 is attached with a collar 19 with screws 20 to the base 1 and installed in front of the transport chute under the receiving nest 21 of the carousel 22.

Vibrating conveyor works as follows.

The parts 7 under the action of vibration, moving along the helical guide 11, enter the transport chute formed by the supporting guide 3 and the additional 1 with the straight guide 4. At the same time, the whole flow of parts 7 is located on the supporting guide 3, which informs the parts to be thrown movement to provide microflights. Incorrectly oriented parts 7 fall into the window 13 of the screw-like direction to dei 11, which has a slope of 12 ° towards the center of the bunker bowl b. The flow of parts 7, moving ho of the supporting guide 3, approaches the zone 17 of the magnetic attraction of the permanent magnet 18. At the same time, the first part 7 moves off from the flow and instantly is pulled by the magnetic field of the constant magnet 18 into the receiving socket 21 of the carousel 22, performing an intermittent rotation in the direction of a. The first detachment moment in the direction of movement of the part 7 is monitored by the sensor 16 and a signal is output through the control means 15 to turn on the controlled magnet 14. With the magnet 14 turned on, the entire flow of parts 7 located on the supporting guide 3 is pressed by the magnetic field to the additional guide 4 insulated from the reference bearing 3. An instantaneous deceleration of the flow of parts 7 occurs. When the control magnet 14 is turned off by the control means 15, the operation cycle repeats.

During the main operation time of the fed automaton, the flow of parts 7 is located on the additional direction 4, isolated from the support rail. At the same time, children 7 are not subject to the action of backwaters and vibrations, which reduces the likelihood of flow sticking in the transport chute and sharply increases the reliability of vibration loading, reduces the possibility of mechanical damage to the surface of parts 7. Parts 7 are subjected to vibration only for the time required for loading, which significantly less cycle time. The support of the parts 7 is transferred to the open part of the flow to zone 12 — the point of junction of the transport chute with the helical direction to the tank 11, which has a slope 12, falls into the bowl of the bunker. B. The parts are subject to vibration only for the time required to feed the part to zone 17, which is significantly less than the cycle time of the fed machine.

In the zone 17 formed at the exit of the transport chute, the transported parts are missing. This avoids mechanical contact of parts with various types of cutters, gate valves, etc. By increasing the magnetic force of the permanent magnet 18, the zone 17 can be lengthened.

The use of the proposed vibrating conveyor allows to increase the reliability of vibration loading and reduce the possibility of mechanical damage to easily deformable parts and parts with easily broken cover due to the exclusion of the influence of the sub-vibration and seizure.
