Description

Centering equipment, in particular for the plastering saw - ——

Technical field

The technical solution relates to a centering device, in particular for a plastering saw, in front of which an insertion conveyor is placed and a separator conveyor is located behind its outlet.

BACKGROUND OF THE INVENTION

A number of lumber centering solutions for sawing machines are known. Frequent solutions include centering by the operator, for example, by mechanical or hydraulic means.

CS copyright certificate No. 258 554 mentions prisms in front of the saw. This device consists of adjusters, which are adjuster is provided with collets sliding on the swinging shaft. Each with hydraulic clamping cylinder and stepping hydraulic cylinder. This stepping hydraulic cylinder has a common piston rod, the latter fixed by the cylinder.

with a second walking hydraulic cylinder, the walking hydraulic cylinder is attached to the bracket to the swing shaft and provided with the swing hydraulic

A device for precisely adjusting saw blades, guide blades and cutouts in a frame saw by means of a laser is described in CS author's certificate 234 708. Its essence lies in the positioning of the laser and also in the formation of the optics body. The optic lasers are supported by a servo-drive displaceably mounted on a fixed beam above the rails between the clamping carriage and the auxiliary carriage on which the cut-out is established.

A device for automatic centering of side timber in front of a double plastering saw is described in CS author's certificate 205 984. The essence of this device is that it consists of two centering devices arranged one after the other, with a measuring bar above the first one. One of these centering devices is connected to a hydraulic cylinder circuit with an electrohydraulic valve and a displacement sensor. A movable saw is connected to another hydraulic cylinder with an electrohydraulic circuit and feed sensor. The measuring bar as well as the electrohydraulic circuits are connected to the control device.

The essence of the technical solution

Based on the knowledge of the prior art, it is the object of the invention to provide a long-term reliable centering device, in particular for a plastering saw, with a high throughput and maximum limitation of human factors, which can be incorporated into the lumber processing line without further modification.

The device according to the present invention, in which at least seven conveyors are disposed parallel to the longitudinal axis of the conveyor, is provided along the part of one side of the insertion conveyor, at least seven of which are transversely Optoelectric switches, preferably two optoelectric sensors, preferably a cross conveyor is connected thereto, connected to a control unit, which is connected to at least two pairs of mutually adjustable centering arms movable at least between optoelectric sensors and an insertion conveyor, to saw spindles and to pressure rollers. The free ends of the centering arms have a maximum distance from each other in the extended position of the pressure rollers.

The arrangement of individual functional nodes of the device according to the technical solution enables to perform several technological operations simultaneously, which significantly increases its performance. Equipment

enables, without limiting the collection of produced boards, an automated supply of timber from the area before and after the plastering saw by two material flows.

Other dependent claims.

features of the technical solution are given

In order to ensure an optimum supply of sawn timber, it is advantageous if a longitudinal conveyor is arranged parallel to the feed conveyor on the side of the optoelectric sensors which faces away from the feed conveyor. In this case, the transverse conveyor extends to the longitudinal conveyor, which may advantageously have an integrating device.

equipment

To ensure optimum adjustment conditions with respect to the anticipated dimensions of the timber, it is advisable that the control unit is programmable.

For convenience, if and / or the control of the saw rollers are each connected to simplify the control of the operation of the device there is at least one optoelectric headstock sensor and / or control of a pressing light-emitting diode which can be located in the inner part of the control unit switchboard.

Description of the drawings

The technical solution will be described in the following with the aid of a drawing, which schematically shows a centering device for a plastering saw.

DETAILED DESCRIPTION OF THE INVENTION

AND

Centering device for the plaster saw shown in

In the drawing, it consists of a longitudinal conveyor 1 having an integrating device 3. A transverse conveyor 4 is formed transversely to the longitudinal conveyor 1 and extends below a series of seven optoelectric sensors 8. Below these optoelectric sensors 8 also intervene on the The centering arms, which are not shown in greater detail in the drawing, are movable between the optoelectric sensor 8 and the insertion conveyor 4. This insertion conveyor 4 is directed parallel to the longitudinal conveyor 1 and a series of optoelectric sensors 8 into the plastering machine 6. The insertion conveyor 4 is formed by pressure rollers 5. A separating conveyor 7 is arranged downstream of the plastering saw 6.

The optoelectric sensors 8 are connected to a programmable control unit 9. This programmable unit 9 is in operative connection with the saw headstocks of the plaster saw.

6. and with pressure rollers J5. All these control, respectively. the controlled headers, i.e. the optoelectric sensors 8, the saw headstocks of the plaster saw 6 and the pressure rollers 5 are each connected to one light-emitting diode. These light emitting diodes, which are located in the main switchboard and are only accessible to authorized and trained operators, can be used to monitor the function of the connected elements during the duty cycle, and can significantly reduce downtime for repairs that have an immediate impact on the overall file performance.

Dashed in the drawing is a possible addition of the above-described device for centering further mirrored to the longitudinal axis of the feed conveyor 8 by a series of optoelectric sensors 8, centering arms, a cross conveyor 2 and a longitudinal conveyor 1, their mutual positioning being the same as above.

The lumber is first placed on the longitudinal conveyor 1, where it is first sealed on the tanning device 3. Then the cross conveyor 2 moves the timber under the optoelectric sensors 8, which measure it widthwise and at the same time according to the number of shaded sensors 8. | determines its length. The timber length thus determined corresponds to two

pairs of centering arms which move the lumber from the area below the optoelectric sensors 8 to the insertion conveyor 4 and at the same time center it. Depending on the width of the sawn timber, the headstocks are set from the control unit 9 and at the same time the pressure rollers 5 are pressed against the sawn timber simultaneously. At the same time, their centering arms are opened and the sawn timber is inserted into the plastering saw 6.
