Description

The proposed solution relates to the timber industry, and more specifically to timber rafting.

A device for the formation of a timber-alloy beam is known, consisting of a storage device, an end-end device equipped with a device with movable end-end shields, in the middle part of which through holes are made and equipped with hollow cones for installing a movable pneumatic pipeline in them for supplying crushed material with a removable soft container installed on it for crushed material, see Patent for a useful model of the Russian Federation No. 189344 "Device for the formation of a timber alloy beam". IPC B65G 69/20, 2018.

The disadvantage of the known design for the formation of a timber-floating beam is low productivity, since the formation of a timber-floating beam is carried out sequentially, operational limitation, since the known device allows you to form a beam only from logs of one type (assortment).

The technical result achieved by the inventive device consists in increasing the productivity and expanding the operational capabilities of the device by increasing the granularity of sorting and ensuring the simultaneous formation of beams from different types of logs (assortments) and by parallel combining different forming operations.

The technical result is provided by the fact that in a device for forming a timber-alloy beam, including a storage device, an end-facing device equipped with a device with movable end-facing shields, in the middle part of which through holes are made and equipped with hollow cones for installing a movable pneumatic pipeline in them for supplying crushed material with mounted on it is a removable soft container for crushed material, the storage device is made separately from the facing device and consists of several interconnected receiving tables with the possibility of moving them and placing assortments on them with the possibility of moving the assortments, while the facing device is made on a separate table with the ability to move the table and contains separate receivers for assortments, made with the possibility of forming a timber beam.

The device for the formation of a timber-floating beam consists of interconnected receiving tables 1 of a storage device with the possibility of moving them and placing assortments on them with the possibility of moving the latter, an end-cutting device 2 placed on a separate table 3 with the possibility of moving it, for example, rotating around a vertical axis, equipped with devices with movable end shields 4, which in the middle part are made with through holes and are equipped with hollow cones 5, which form a hollow niche 6 of the bundle, straps 7 for the bundle, a movable pneumatic line 8 for feeding crushed material with a removable soft container 9 for crushed material and receivers 10 for assortments, made with the possibility of forming a timber beam, for example, a cradle with folding stands.

The device for forming a timber floating beam works as follows.

Assortments C with the help of the manipulator M are placed by grade on the corresponding receiving tables 1. When one table is filled to the volume of the beam, this table moves to the facing device 2, which is in position I, and the assortments are dropped from the table into the facing device 2.

By increasing the number. of receiving tables of the storage device, the operational capabilities of the device are expanded by ensuring an increase in the sorting fraction and simultaneous formation of bundles from different types of logs (assortments).

Previously, in position I, the end panels 4 with hollow cones 5 are pushed apart so that the assortments C cannot fall between the cones 5 (Section A-A in Fig. 2 and View D in Fig. 6).

Assortments C are discarded from the storage table 1 and are placed around the cones 5, forming a hollow niche 6 in the middle part of the beam.

Then the facing device 2 is moved to position II, where strapping 7 is applied to the beam without pulling them (Section B-B of Fig. 3).

After that, the end shields 4 with hollow cones 5 move towards each other, as a result, spacer forces arise, which leads to the expansion of the assortments C. Due to the limited length of the strapping 7, the beam tends to take the shape of a circle in cross-section, which gives it strength (Section B-B fig. 3).

Then the end device 2 is moved to position III, where a movable pneumatic line 8 is introduced into the formed niche 6 for supplying the crushed material with a removable hollow soft container 9 installed on it (Section B-B Fig. 4). After that, the crushed material is fed into the container 9 through the pneumatic line 8 until the container 9 is completely filled (Section B-B of Fig. 4). The container 9, filled with crushed material, provides the necessary buoyancy and stable draft of the raft.

Then the facing device 2 is moved to position IV, where the facing shields 4 with hollow cones 5 are pushed apart until the beam is completely released. After that, the racks 10 are folded back for further operations with a fully formed beam, for example, taking it with a transport unit or dropping it into the water (Section G-G Fig. 5 and View E of Fig. 7).

By moving the end-end devices 2 to positions I-IV, an increase in the productivity of the device is achieved by parallel execution of operations to form a timber-floating beam.

Thus, the proposed solution makes it possible to increase the productivity and expand the operational capabilities of the device by increasing the fractionality of sorting and ensuring the simultaneous formation of beams from different types of logs (assortments) and by parallel combining different forming operations.
