Description

  . :

The invention is related to mechanical puncture production and can be carried out in devices for the automatic feeding of sheet material with pre-formed edges from a three-fold insert.

A device is known for loading sheets of HBW1B Hulk; The gostavpen contains the grip on the hfpuse, the transfer mechanism to the lever actuator IlJ, the purpose of the invention is to ensure the loading of sheets with bent edges and increase the reliability of the device 6 work.

jQl of this proposed device is equipped with kinematically connected with the mechanism of transfer the mechanisms of mapping the cant of a jaist.

The sheet feeding mechanism is designed to be connected with the drive levers, which are suitable for mounting; loading naprvl kkhtsikh, vaimododetsiykhkhikh with a sheet at the expense of sv Treni.

The sheet turning mechanism is made in the form of a rotary in the loading plane consisting of two telescopically connected | the spring-loaded parts of the lever about the end of which is connected to the drive, ei the other carries the roller "interacting with the sheet,

Automatic feed device

sheets with bent edges do not hold the tare 1, stand 2, grip 3, transfer mechanism 4, rammer 5, to the device in, drive 7 to the table 8. Tare 1 is a welded structure designed for UIS transportation of workpieces 9 sheets with bent {fomkamn From the shower of the operation to the bending rollers 10 The support 2 serves to precisely fit the container I. On the bending riesidsho. The gripper 3 consists of a cross bar ii with two vacuum tubes and unregulated suction cups 12, see the tire on the rod of the pneumatic cylinder 13. To protect the rubber suction cups 12 from mechanical damage on the transverse

Four fuses 14 are installed 11. The cross member of the crossbar mechanism 4 is prevented from turning over the crossbar 11. The guide columns 15 are fixed to the crossbar 11. The pneumatic cylinder 13 with crossbar 11 is fixed to the cross member 16 of the mechanism 4.

The transfer mechanism 4 is a four-star hinged mechanism, made in the form of a parallelogram, it consists of a crosspiece 16 with bushings 17 under the guide column 15, a split sleeve 18 for fastening the pneumatic cylinder 13; two with water levers 19, seated on shaft 2O, and two non-driving levers 21. Levers 19 and 21 of the yoke 16 are connected to the uprights 22 mounted on the table 8. The shaft TO receives rotation from the actuator 7 by means of a rail 23 fixed to the rod of the pneumatic lindra, and the gear wheel 24, s.nd sego on the shaft 2O,

clutches with the workpiece 9 are covered with scrap materials having a friction coefficient, for example rubber, two pairs of levers 27 and a common axis 25. 5 agitator from the shaft 2O by a hinge mechanism containing a rocker arm 28 "a connecting rod 29 and a DZ lever rigidly connected to one of the levers

The tilter 6 contains a spring-loaded plug 31, having the possibility of axial movement in the lever 32 .. (: one

passage bent on the end of the workpiece 9 when it is captured by rolls of sheet bending rollers 1O. The lever 32, which is mounted on the shaft 33, receives the rotation of the shaft 2O through the gears 24 and 34, the shaft 35, the frictionless coupling 36 mounted on it and the chain transmission 37. To activate the rotation, the coupling 36 is controlled by a cam 38, which The lever 39 presses the spring-loaded half coupling and breaks the kinematic chain. On the shaft 33 there is installed a phrashchionny brake 4O, a fixed arm 32 of the tilting device 6 when the kinematic chain is opened by the clutch 36, the actuator 7 is a pneumatic cylinder with throttle speed control. A rail 23 is attached to the cylinder rod. A cylinder is mounted on the stand 41, which in turn is fixed to the foot 8. On the table 8, all the device assemblies are mounted except for tare 1 and post-2. An automatic link 42 is mounted in the table niche device and bending rolls in AV TOMaTH4f “KOM mode.

When moving the rail 23 to the right, the transfer mechanism 4 moves the gripper 3 to tare 1 to the loading position. In this position, the rod of the pneumatic head 13 lowers down on the foot of the workpieces 9 the cross member 11 with the CFA of the I 12. The olasA of the workpiece 9 is captured and the cross member 11 with the seized workpiece moves upwards. After this, the transfer mechanism 4 moves the grip

At the left end, the initial position and the workpiece 9 are dumped / run on guide rails 26 to the gate 5, the rammer 5 into the tilter in parallel with the mechanism 4. During the movement of the mechanism

4 transfer to the right to e & re 1 rammer 5 feeds the workpiece 9 left over from the previous cycle into the work rolls of the bending rollers 1O. When the mechanism 4 of the transfer with the catch 3 releases the zone above the rotary lever 6, the roller of the lever 39 drops into the trough of the cam 3 and the clutch 36 starts the rotation of the shaft 35 and the tilter 6 raises the right end of the workpiece 9, ensuring the work rolls of the bending rolls rollers lOj ..

When the transfer mechanism 4 is moved to the left to its original position, tilter 6 is lowered down, and the rammer 5 is moved to the right to its original position. Preparation 9 is dropped to guide-26 of the rammer 5 and the cycle repeats.
