Description

The invention relates to transport engineering and can be used for transportation and sorting of timber at the enterprises of the forest and woodworking industries.

The aim of the invention is to increase reliability.

In FIG. .1 shows a conveyor, a general view with a cut along the axis; in FIG. 2 - the same at the time of discharge; in FIG. 3 - the same, in plan, in the area of the drive; in FIG. 4 - section A — A in FIG. 1, rolling bearings are made; in FIG. 5 - section B — B in FIG. 2, rolling bearings are made; in FIG. 6 is a section A — A in FIG. 1, sliding bearings are made; in FIG. 7 — section B — B in FIG. 2, made, sliding bearings, the groove in the bearing is inclined relative to the guides in the direction of movement of the beam.

The longitudinal conveyor includes a traction body 1, connected by means of step ladders 2 with traverses 3, moving along the longitudinal guides 4 on the supports 5, which are mounted on the axles 6 mounted on the arms of the traverse 3. The axles 6 are made in two stages, and the diameter of the smaller step 7 in the supports 5, a groove 8 is made, and along the diameter of the larger stage 9, a hole 10. A groove 8 and a hole 10 are connected to each other. On both sides of the traction body 1 with traverses 3 there are drives 11, in the area of which the longitudinal guides 4 are equipped with dropping mechanisms in the form of retractable chippers, made, for example, in the form of plates 12 located in a vertical plane at an angle to the guides 4, and having drive mechanisms, such as electromagnets (not shown). The supports 5 have elastic return elements, which are made, for example, in the form of conical springs 13. One end of the springs 13 is rigidly fixed in the hole 14 located on the opposite side of the groove 8, and the other is movable on the axis 6. In addition, the groove 8 is made with an inclination relative to the guides in the direction of movement of the traverse.

Supports 5 can be made either rolling (Fig. 4, 5), or sliding (Fig. 6,7). Traverses 3 have saddles 15, limiters 16 lateral displacement of the traction body in the area of the plates. Axes 6 have flanges 17 at the ends.

The longitudinal conveyor operates as follows.

Timber (assortments, logs) are delivered individually to saddles 15 of traverse 3 and are moved along longitudinal guides 4 by means of traction body 1 along the storage front. After the command to reset the assortment to the drive. And (for example, the right one), the drive mechanism for dropping this drive 11 is activated, which pushes the plates 12 (right) into the zone of interaction with the supports 5 of the traverse 3 involved in the transportation of one assortment. The plates 12 are included in the guides 4 (right), forming an obstacle to the movement of the supports 5 (right), due to which the supports 5 are moved from a larger step 9 to a smaller Ί axis 6, which fails (under the influence of the weight of the transported assortment, crosshead 3 and section traction body 1, coming to these traverses) into the groove 8. As a result, the traverse tilts to this support and the log rolls into the drive 11. After the log is reset, the spring 13 returns the axis 6 to its original position. Moreover, at first, due to the rigid fastening of one end of the spring 13 to the support 5 in the opposite side from the groove 8 (such a fastening of the spring 13 provides the greatest force in the direction of the axis return to its original position), a smaller step 7 moves in the groove 8 in the direction of the hole 10 (traverse lift ), and then, due to the preloading of the support 5 by the spring 13, abutting against the shoulder 17, the support 5 passes from the lower stage 7 to the larger 9, i.e. the axis 6 from the lower position in the groove 8 goes to the upper one and is fixed in the support 5 into the hole 10. At the same time, the plates 12 (right) are removed from the zone of interaction with the supports 5, thereby eliminating the dumping of logs from the traverse 3, following from behind. The execution of one of the ends of the spring 13 movable on the axis 6 provides the rotation of the support 5 (rolling) relative to the axis 6.

When exposed to supports 5 with plates 12, the support of the traverse 3 from lateral displacement is ensured by the tension of the traction body 1. When discharging large timber, the traverses can be fixed with limiters 16, which are located in the area of the plates 12 and limit the traction body 1 from lateral displacement when moving it with traverses 3 in zone, forest stores 11.

Similarly, the dumping of timber occurs when the drive is located on the other side of the traction body 1 (to the left).

Claims (3)

The invention relates to a transport engineering industry and can be used for transporting and sorting timber products in enterprises of the timber and woodworking industry. The aim of the invention is to increase reliability. FIG. .1 shows a conveyor, general view with an axial section; in fig. 2 - the same at the time of reset; in fig. 3 - the same, in plan, in the storage zone; in fig. 4 shows section A-A in FIG. 1, rolling bearings are made; in fig. 5 is a section BB in FIG. 2, rolling bearings are made; in fig. 6 shows section A-A in FIG. 1, the slide bearings are made; in fig. 7-section BB in FIG. 2, the sliding supports are made; the groove in the support is inclined with respect to the guides in the direction of movement of the traverse. The longitudinal conveyor includes a traction body 1, connected by means of the stirrups 2 to the cross-arms 3, moving along the longitudinal guides 4 on the supports 5, which are mounted on axles 6, mounted on brackets 3, and the axes 6 are made in two stages. diameter. Mensp1 stage 7 in the supports 5 is made a groove 8, and the diameter of the larger stage 9 - hole 10. The groove 8 and the hole 10 are connected to each other. On either side of the traction body 1 with cross-beams 3, there are storage devices 11, in the zone of which the longitudinal guides 4 are equipped with drop mechanisms in the form of retractable bumpers made, for example, in the form of plates 12 arranged in a vertical plane at an angle to the guides 4, and available actuators, for example electromagnets (not shown). The supports 5 have elastic return elements, which are made, for example, in the form of conical springs 13. One end of the springs 13 is rigidly fixed in a hole 14 located in the photo-opposite side of the groove 8, and the other is movable on the axis 6. In addition, the groove 8 is made inclined relative to the direction of movement of the traverse. The supports 5 can be made either by rolling (Fig. 4, 5) or sliding (Fig. 6,7). The cross members 3 have seats 15, limiters 16 of the lateral displacement of the traction organ in the area of the plates. Axis 6 are at the ends of the flange 17. The longitudinal conveyor works as follows. Timber materials (assortments, logs) are fed individually to the saddles 15 of the traverse 3 and are moved along the longitudinal guides 4 by means of the traction device 1 along the storage front. After the command to reset the assortment to the accumulator 11 (for example, right) is triggered, the drive mechanism for dropping this accumulator 11 is activated, which pushes the plates 12 (right) into the zone of interaction with the supports 5 of the traverse 3 involved in transporting one assortment. The plates 12 enter the guides 4 (right), forming an obstacle in the path of movement of the supports 5 (right), whereby the supports 5 shift from the larger step 9 to the smaller 7 axis 6, which fails (under the weight of the transported assortment, traverse 3 and the section of the traction device 1, which comes to these traverses) in the groove 8. As a result, the traverse tilts on this support and the log rolls into the hopper 11. After resetting, the log spring 13 returns the axis 6 to its original position. Moreover, first, due to the rigid mounting of one end of the spring 13 to the support 5 in the opposite direction from the groove 8 (this mounting of the spring 13 provides the greatest force in the direction of returning the axis to its original position), a smaller stage 7 B moves to the groove 8 in the direction of the hole 10 (lifting the cross member ), and then due to the compression of the support 5 by the spring 13, which abuts against the flange 17, the support 5 passes from the lower stage 7 to the large 9, i.e. axis 6 from the lower position in the groove 8 passes to the top and is fixed in the support 5 to the hole 10. At the same time, the plates 12 (right) are withdrawn from the zone of interaction with the supports 5, thus preventing the dumping of the traverse logs 3 following behind . Making one of the ends of the spring 13 movable on the axis 6 ensures the rotation of the support 5 (rolling) relative to the axis 6. When exposed to the supports 5 with the plates 12, the traverse 3 is kept from lateral displacement by tensioning the pulling member 1. When shedding large-sized timber, the traverse can be fixed mi 16, which are located in the zone of the plates 12 and limit the lateral displacement of the traction device 1 when it moves with the cross pieces 3 in the area, of the forest storages 11. Similarly, the timber is dumped when the accumulated bodies on the other side of the traction body 1 (left). Claim 1.
