Abstract

The invention relates to an automatic transport loading device. The purpose of the invention is to improve the reliability of the device by ensuring a smooth movement of the receiver. On the shaft 3 there is a receiver, made in the form of a two-armed lever, rotatable around the shaft 3. On one shoulder 10 of the lever the grip is sized, and on the other - the roller. 17, designed to interact with a profile cam 24, kinematically connected with the shaft 3. On the rotor disk 21, spring-loaded pushers 20 are mounted, which at one end interact with the cam -22 and the other with the lever. A piece 7 enters the grip of the lever from the magazine 8. When the rotor rotates, the pusher 20 from the cam 22 receives movement and, interacting with the lever, turns it around the shaft 3 along the path of movement of the slots 6 for the parts. During this movement, the part 7 is moved from the gripper to the nest 6. With further rotation of the cam, the roller 17, in contact with the cam 24, turns the lever in the opposite direction. 4 i-sh. 1C

The invention relates to a machine building, namely, to asTOMaTtraecKHM transport-loading devices of machine tools and automatic lines, /.

The purpose of the invention is to expand the operation of the loading device by ensuring the smooth movement of the receiver.

FIG. 2 shows a boot rack, a section in FIG. 2 is a section A-A in FIG., In FIG. 3, a section BB in FIG. 1. (the initial position of the intermediate receiver) 5 in FIG. 4 - - the same, return position prome; ku-J5 accurate receiver.

The loading device consists of a base 1, a rotor 2 having a hall mounted at the base 1, a rotational drive shaft 3 of the rotor 2 (not shown) 20 mounted on the shaft 3 an asterisk 4 and a transport chain 5 with carriers (slots) 6 parts 7. Vertical magazine 8 is fixed on the base t at the loading position and is located above the rotor 25 of the transport circuit 5 with the carriers 6. The intermediate receiver is made in the WI of the two shoulders of its lever 9 ,, on one arm 10 of which the receiver JQ sleeve is fixed t1 capture located on the trajectory of of the transport chain 5 with carrier 6, bracket 12 with window 13, coaxial receiving sleeve It, and supporting lug 14, and on the other arm 15 of two shoulders lever 9, axis 16 with roller 17 is attached. 4 of the rotor 2 to the shaft 3 can be rotated relative to 0 of the vertical magazine 8 and is pressed against the stop t8, mounted on the base I, by the spring 19, (FIG. 2),

The intermediate receiver leads in 45 seconds by using spring-loaded pushers 20 located above the intermediate receiver in the disk 21 of the rotor 2 mounted on the shaft 3. The pushers 20 are driven in the direction of the intermediate receiver with cam 22,. rigidly fixed above them in the position of t in the loading position. The intermediate receiver is rotated by lowering the pusher 20 from the cam 22 and hooking it to the support lug 14 located under the pusher 20.

On the base 1, on the periphery of the rotor 2, an axis 23 is fixed, on which a profile cam 24 is installed with the possibility of interaction with a roller 17 mounted on an axis 16 mounted on a shoulder 15 of a double-arm lever 9.

Gear 25 coaxially fixed with profile cam 24, kinematic} 1 ki associated with gear 26 fixed on shaft 3. On base 1 between the intermediate receiver and sprocket 4 of the rotor 2 fixed mio pin 27 for parts 7 with a window 28 located on the path of movement of the transport chain 5 at a certain angle from the initial position of the intermediate receiver in the direction of its movement from the initial position. The bracket 12 has a bearing surface 20 for the parts 7 located opposite to the window 13 in the direction opposite to the intermediate receiver is the original overlay,

The boot device works as follows

The parts 7 from the vertical magazine 8 are snapped (not shown) one by one through the window 13 of the bracket 12 into the receiving bushing 11 of the intermediate receiver and rested with the bottom end into the bearing pad 27.

In the initial position, the intermediate receiver is compressed by a spring 19 against the stop 18 of the two shoulders lever 9.

During the rotation of the shaft 3, the spring-loaded pusher 20 mounted in the disk 21 is lowered from the cam 22 and rests against the support lug 14 of the double-arm lever 9 and turns its angle ya. At the moment of contact of the pusher 20 with the supporting lug 14, the carrier 6 of the transport chain 5 is located coaxially with the receiving sleeve 11, and the profile cam 24 faces the roller 17 with a constant radius and does not touch it (FIG. 3),

During the rotation of the intermediate receiver at some angle, the part 7 slides along the support platform 27, and the transport carrier 5 moves synchronously along its path coaxially with the receiving sleeve 11. When the lever 9 is rotated by the angle of the window 28 of the support platform 2 / part 7 falls through it into the carrier 6 of the transport chain 5,

At this time, the profile cam 24. Thanks to the kinematic connection of the gear 25 with the gear 26 turns to the roller 17 as far as possible from its axis, and the pusher 20 moves away from the supporting surface of the cam 22 and is denied from the support lug 14 of the two shoulders 9.

The double-shouldered lever 9 with the spring 19 tends to return to its original position and is pressed against the variable profile of the profile cam 24. With further rotation of the cam 24, the roller

a rotor, on a disk of which evenly circumferentially placed are the sockets for parts, and spring-loaded pushers, a vertical magazine located above the rotor in the loading position, an intermediate receiver located between the magazine and the rotor and made in the form of a lever, on the shoulder of which the size is 10; rotatably mounted around the axis of the rotor by means of a pusher interacting with a cam mounted on

The basis, characterized by 17, in contact with decreasing by radio- 5 in that, in order to increase the reliability of the variable profile of the device's profile of operation, it is equipped with a cam 24, turns the two shoulders with an additional profile cam, the lever 9 in the opposite direction, having been installed with the ability to rotate — the ability to smoothly approach the boom and kinematically connected with the shaft RU 18. 20 of the rotor, and the intermediate receiver lever is two-arm, moreover, its second arm is designed to interact with the above profile Lacko.
