Description

The invention relates to the design of the feeding devices for formatted cutting materials and can be used in the woodworking industry.

The purpose of the invention is to increase the reliability of the device.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one.

The device for positioning and feeding sheet materials into a cutting machine comprises a lifting table 1, equipped with horizontal rollers 2, basing vertical rollers 3 and stops 4, mounted on horizontal guides 5 carriage 6 with a drive 7 of its reciprocating movement. The carriage 6 has three or four front pushers 8 installed in a row and three or four rear pushers 9 positioned relative to them, power cylinders 10 and 11 for raising the front and rear pushers 8 and 9. On the carriage 6, a mechanism is also mounted the transverse-based sheet materials are in the form of two horizontally placed ram cylinders 12, the rods 13 of which are connected to the pushers 9 by means of a horizontal beam 14 and a rod 1.5. Between the movable table 16 of the cutting machine for sheet materials and the lifting table 1, a mechanism for longitudinal base is installed, which contains non-driving rollers 18 mounted on the frame 17, fixedly mounted parallel to the movement of the carriage 6, the baseline 19, the power cylinder 20 with a shaft 21 connected through mounted in the guides 22 pushers 23 with stops 24, while the stops 24 are arranged parallel to the movement of the carriage 6 with the formation between the ruler 19 of the free zone for the passage of the pushers 8 and 9.

On the frame 17, the stop 25 is rigidly fixed, the upper surface of which is located at the same level with the rollers 18, and its end is located coaxially with the lateral internal generator of the rollers 3. In addition, on the carriage 6 and the frame T 7 the mechanism of stepless movement of the power cylinders 12 20 along their longitudinal axes, executed in the form, for example, of screws 26 and 27 that are turning from the flywheels

28 and 29 and their associated movable along screws 28 and 29 nuts 30 and 31, which are rigidly connected to the cylinder bodies 12 and 20. Behind the frame 17, there is a machine for cutting sheet materials, having a table 16 installed in the guides perpendicular to the movement of the carriage 6 direction and having a stroke longer than the length of the sheet material to be cut. On the stationary beam of the machine, saw blades 32 for lengthwise cutting of sheet materials and one, moving in the direction normal to the movement of the table, saw blades 33 for cross-cutting of sheet materials, and saw blades 32 and 33 provided with cutting tools 34 are disposed in a direction perpendicular to the movement of the carriage 6 for free passage over the table 16 of the stops 8 and 9. Behind the table 16 there is a section 35 for receiving the blanks after ARMS.

The device works as follows.

Before the start of operation, the carriage 6 with the raised pushers 8 and 9 is in the initial position above the lifting table 1, and the latter is in the lowest position, with. In this case, the initial positions of the table 1, the carriage 6, the pushers 8 and 9 are controlled by limit switches.

Depending on the dimensions of the sheets to be cut, cylinders 12 and 20 of the transverse and longitudinal base are installed by means of flywheels 26 and 27 in the required position.

Then loaded on the rollers 2 lowered lifting table 1 stack 36 sheet materials. After that, the pushers 8 and 9 simultaneously lower, and the lifting table 1 rises to a height at which the upper level of the stack 36 of sheet materials does not exceed the level of the rollers 18 of the longitudinal-based mechanism by the thickness of the package being cut 37. After raising the table 1 and lowering the pushers 8 and 9 on a given height of the path switches give the command to move the carriage 6 in the direction of the machine and the inclusion of the latter in the work, with the pushers 8 and 9 in front of the engine

The carriage 6 encompasses the stack 36 in width with a gap.

After the drive 7 of the carriage 6 is turned on, the carriage 6 begins to move toward the machine, seizing the pushers 9 of the bag 37 and shifting it to the upper surface of the abutment 25 and rollers 18, while the sheet materials located under the bag 37 are prevented from moving by the end surfaces of the abutments 25. After complete transferring the bag 37 to the rollers 18 is instructed to turn on the cylinder 20 of the longitudinal-based mechanism, while the screw 29 extends in the direction towards the clamping ruler 19 until the stops 2 contact the side end of the bag 37, moving the latter to rollers 18 to the contact of the other side of its side with the ruler 19.Pro-20 F about the basing of the package of 37 sheet materials on its short side. The stops 24 are retracted to the initial position and the cylinder 12 of the transverse-base mechanism 25 is activated, which moves the rear followers 9 through the rod 13 and 15 and 15 and, together with them, the bag 37 towards the front. pushes them, pressing it against the latter and basing the sheets in the bag along the long edge. Next, the bag 37, sandwiched between the pushers 8 and 9, is transmitted in the cleaved state to the table 16. The cylinder 12 is actuated. The lateral cutting is carried out during the return stroke of the table 16, when it is stopped by the command of the switching off of the bodies in a predetermined position, including the drive for moving the slide 33, during the movement of which the lateral cutting is carried out.

The carriage 6 in the process of longitudinal cutting moves to the original floor

 0, including raising the table 16 and lowering the pushers 8 and 9. After returning the table 16 to the initial position, the carriage 6 is turned on to the working stroke. The cycle then repeats. The cut pack 37 collides from the table 16 to the receiving portion 35 by the front pushers 8 when loading the next pack on the table 16.
