Abstract

FIELD: forest industry. The aim of the invention is to increase the productivity of sawing by providing clamp-free sawing. The device includes mobile carts with arms and arm supports 3 and 4 installed in pairs. Levers 3 and 4 are made with a curved surface and are interconnected by a flexible thread 5. At the lower ends of the arms 3 and 4 there are fingers 6 and 7. Finger 6 moves along horizontal side rail 8 in the form of a slot in the frame 9, Cat-: the lever 3 moves along the guide in the form of a slot in the upper horizontal surface of the frame 9. Finger 7 s, it rings along the lower horizontal Ook guide I1, the lever 4 itself in the form of a notch the lower horizontal surface of the frame 9. The levers 3 and 4 have points 13 in the form of sockets for fixing the flexible thread 5 in them; The guides 8 and I are located horizontally at different heights of the frame 9. After the package of timber has been placed on the grips, the drive 16 is turned on lower "

the ends of the levers. In this case, the package of timber is lifted onto flexible threads x 5 and clamped with the upper ends of the arms and flexible thread around the entire perimeter of the bag and hanging the parts of the bag cut off. Under the force of gravity

The free end of the sawn-off part of the timber package is lowered onto the opened levers as the cut is increased. A gap is formed between the part to be cut and the whip package, which eliminates the clamping of the saw. 1 z.p, f-ly, 6 ill.

The invention relates to the forest industry and can be used to open packs of logs for assortments on stock exchanges of raw materials for pulp and paper mills, timber transshipment bases and lower stocks of logging companies.

The purpose of the invention is to increase the productivity of sawing by providing clampless sawing.

FIG. 1 and 2 shows the receiving device, a general view; in fig. 3 - capture, general view; on .fig. 4 shows section A-A in FIG. 3; in fig. 5 - capture from the butt part of the timber package; in fig. 6 - the same, from the top part of the timber package.

The device includes movable I carts 1 with legs 2 mounted in pairs on them, each of which joins two levers 3 and 4 with a curvilinear surface that can be moved relative to each other and interconnected by a flexible thread 5. The arms 3 and 4 have fingers 6 and 7 respectively. The lever 3 is provided with a finger 6, the length of which allows it to freely pass inside the rod 4 along the horizontal side guide 8 in the form of slots on the frame 9 of the cross bar, and the lever 3 moves along the guide 10 in the form of a slot in the upper horizontal surface of the frame 9 traverse. The finger 7 of the lever 4 slides, respectively, along the lower horizontal lateral rails 11 in the form of slots on the frame 9 of the cross bar, and the lever 4 itself shows the matching 12

in the form of slots of the lower horizontal surfaces of the frame 9 traverse. Levers 3 and 4 have points 13 in the form

sockets for fixing in them flexible

thread 5, which is about 0.5 length of the lever. The nests are removed from the upper ends of the levers at a distance approximately equal to 2/3 of the length of the flexible thread 5. To drive the levers 3 and 4 and clamp the package of timber on a finger; A cable loop is attached to 6 and 7, the ends of which 14 and 15 are connected to the drive mechanism 16.

The device works as follows.

Before loading the package of timber into the receiving device, the trolleys 1 with the legs 2 installed in pairs, being in the opened position, are placed in accordance with the required lengths of the assortments. After laying

on the arms of the grippers include a mechanism for driving the working stroke of the lower ends of the levers, as a result, they start to move towards each other (Fig. 4), and during the passage of the center of the frame 9, the crossheads are removed from each other (Fig. 5), causing turning the upper ends of the levers around the attachment points 13 of the flexible thread 5. In this case, the timber package is lifted onto flexible threads 5 and clamped with the upper ends of the arms and the flexible thread around the entire perimeter of the bag (Fig. 4 and 5) on both sides of the cutting plane and hanging sawed off h stey package (for

as far as the outermost grips remain open). Gaps 17 are formed between the ends of the packs and the extreme grippers (Fig. 2).

Under the influence of force of the body

The poor end of the sawn-off part of the timber package falls on the opened levers as the cut is increased. A gap is formed between the part to be cut and the whip package, which excludes the possibility of clamping the sawing body with sawn timber. After sawing off the hung part, the sawing organ is removed from the saw and moved to the opposite end of the timber package (to the new cutting place), and the last grip is closed. In this case, a package of assortments is formed from the sawed-off part of a pack of assortments that is ready to be transported by the maxillary loader. After the loader clamps the bag of assortments, the extreme levers and levers on either side of the complete cut are opened by activating the drive mechanism 16 to open the levers. The package of assortments is removed, and the package of timber becomes prepared for a new cut, as part of the package is sawed off as a result of the opening of the new extreme grip becomes reefficient.

Pr. The proposed device is simple in construction, provides no12942
