Description

The invention relates to the field of loading devices for automatic machines and automatic lines and can be used in the electronics industry, instrument engineering, precision engineering, and electronics.

The aim of the invention is to increase the reliability of the device by stopping the store more accurately.

Figure 1 shows the device, a general view; figure 2 is a view of And figure 1; on fig.Z - section BB in figure 1; figure 4 - section bb In figure 1.

The boot device contains a vibrating hopper 1, a manipulator 2, a magazine 3 with a mechanism for stopping it.

The magazine consists of a base 4, to which the housing 5 is attached, into the inclined boring of which the shaft 7 is mounted in bearings 6. On the upper cantilever end of the shaft 7, there is a tapered disk 8 on the key, to which a nut 11 is pressed through the washer 10 by means of a nut 9 the periphery of the windows forming in the collection with the disk 8 sockets for supplied parts. On the lower cantilever end of the shaft 7 is mounted on a key driven coupling half 12 with uniformly spaced around the circumference of the movable pins 13, the number of which is equal to the number of windows in the lining 11. To the inner cone of the coupling half 12 is pressed with its cone coupling half 14 with the cam 15 and gear 16. The clamping of the coupling half 14 to the coupling half 12 is performed by the spring 17, the pressing force is adjusted by tightening the nuts 18. The gear 16 is engaged with the gear 19 mounted on the drive shaft 20 attached through the bracket 21 to the base 4. The hub 5 is fixedly attached to the copier 22. On a bracket 23 fixedly fixed to the base 4, there is a stopper made in the form of a pawl 24 with a finger 25 pressed by a spring 27. To the other fixed bracket 28 there is an electromagnet 29 with a rocker arm 30. With the electromagnet turned off 29, its rocker arm 30 is lowered to the lower position by the action of the spring 31. The magazine mechanism is equipped with a sensor 32 controlling the presence of parts of the disk 8 and a contactless sensor 33 for switching off the drive triggered by the cam 15. To dock with the magazine 3, the vibration hopper 1 has a tray 34 and a pallet 35. A spring 36 is installed in the groove of the coupling half 12, pressed in places of bends to pin 13, which holds the pin in the axial direction during the movement of the coupling half.

The boot device operates as follows.

After receiving the signal from the control system of the assembly complex, the drive 20 is turned on and through gears 19 and 16 rotates the coupling half 14, which is frictionally connected with the driven coupling half 12. In this case, the latter is rigidly connected by the shaft 7 with the disk 8 and is fixed as

of the pins 13, which is the element of the pin memory, is fixed by the pawl 24. At this time, the vibrating bin 1 is supplied with parts that are pre-oriented in the bowl;

34, fall on the disk. 8 and sink into the slots of the lining 11. The dimensions of the sockets are made so that they ensure that no more than one part is loaded into the socket. The extra parts fall onto the pallet 35 and return to the bowl of the vibration hopper 1.

In the course of the rotation of the half coupling 14, the cam 15 mounted on it with its protrusion will act on the finger 25 of the pawl 24,

removes the last and releases the pin 13 of the half-coupling, which was previously captured by the pawl, 12. The joint rotation of the coupling half 12 with the coupling half 14 begins due to the friction coupling existing between them to

as long as the dog fixes the next pin 13. In the case of parts in the slots of the disk 8, all the pins of the coupling half 12 are in the extreme position and are to be gripped by the dog 24, thus ensuring uniform rotation of the coupling half 12 by the step size between adjacent pins, which corresponds to turning the disk 8 by the step size between the sockets and feeding the part to the position of its gripping by the manipulator

2. Half coupling 14 makes one revolution,

after which the drive is turned on

sensor 33, triggered by the cam 15.

In case of missing parts in the slot 8

This detects the sensor 32 (triggered and in the course of rotation of the disk 8) and includes an electromagnet 29, which, attracted by the rocker 30, strikes them along the pin 13 of the coupling half 12 passing by the electromagnet, knocking the pin to the extreme

an upper position in which the latter is fixed by the spring 36. Information on the absence of a part in the slot of the feeder disk is memorized. The drum pin, which was pushed upwards, cannot be captured by the pawl 24, therefore, the emptying slot does not stop at the position of the part capture by the manipulator. In the course of further rotation of the half-coupling 12, the knocked pins 13 are returned to their initial lower position by

their interaction with the profile of a fixed copier 22. Thus, the erasing of the information used and the preparation of the memory mechanism for further work are carried out. If there are several empty slots in the drive disk, the corresponding number of pins of the half-coupling 12 is knocked out and the disk 8 is rotated through a correspondingly larger angle. In the event that the parts stop vibrating (for example, the supply of oriented parts in the bowl is exhausted), the number of successive signals by the sensor 32 to prohibit stopping the disk 8 exceeds the permissible value, and a special electronic device with a counter (not shown) sends a signal that the part supply device is inoperative assembly complex and blocks the work of the manipulator.
