Description

The invention relates to equipment intended for the packaging of wood products, and can be used in the forest industry.

The purpose of the invention is to improve the performance characteristics by ensuring the formation of a symmetric uniform package.

1 shows a device with an offset of the center of gravity of each of the uprights to the outer side relative to its axis of rotation, a general view; figure 2 is the same, side view; FIG. 3 shows a device with elastic elements for returning racks and making parts of a support for receiving timber materials from two elements.

The device includes a base 1 with oppositely mounted on it with the possibility of limited forced rotation in the vertical plane of the uprights 2, the elements of the hinge 3 lines,

semi-rigid slings 4, a support for receiving timber, consisting of parts 5, fixedly mounted on opposite racks towards each other /, and clamps 6 racks 2 with these parts 5 in the raised position.

The clips 6 may include, for example, two-armed levers with rollers 7 at the ends. As shown in FIG. 1, the levers of the magut can be connected with the rods 8 through the yoke 9 rotatably mounted on the base 1, and provided with a return spring 10. The rotation of the struts can be limited, for example, with stops 11 and 12 fixed to the base 1. The elements of the suspension of the 3 straps can be executed and in the form of levers mounted with the possibility of limited rotation, for example, by the stops 13 and 14, in the vertical plane on the upper ends of the uprights 2. There is a pedal 15 at least on one of the latches. 2

mounted on base 1 by means of axes 16. To return racks 2 to their original position relative to base 1, the center of gravity of each of racks 2 relative to axis 16 can be shifted to the outside (see figure 1),

On fig.Z shows another option. In it, each of the support parts for receiving timber is made of two elements. The first one, 17, is either fixedly mounted on each of the racks 2, or is a part of it, and the second one is 18 pivotally fixed on the first one with the possibility of limited rotation, for example, the stop 19 and the plane of the ground 1. Restrictive stops of the rack 2 in FIG. not shown. To return the pillars 2 to their original position, a return spring 20 is installed between each of them, the base 1.

The device works as follows.

Semi-rigid slings 4 are hung on the hinge elements 3. The posts 2 are in the raised position and are held in it by the clips 6.

Timber is loaded into the device using a crane. The dimensions of the palletizer correspond in width and height to the size of the pouch. The timber is placed on the support for receiving timber 5. When the volume of the device is filled with timber, the operator presses the pedal 15, the roller 7 descends from the projection of the stand and releases it. At the same time, the locking of the opposite side is turned through the rods 8 and the yoke 9 and releases the opposite leg. Under the weight of the timber, the pillars 2 turn inwardly up to the stops 12, dragging down the supporting parts 5 to receive the timber (see Fig. 1) or elements 17 and 18 (see Fig. 3) until they stop against the surface of the base 1. As a result, the package of timber hangs on the lines 4. The design must provide for a minimum gap between the planes of the supporting parts 5 that are lowered downwards for receiving the timber, (see figure 1) or between the planes of the elements 18 that are falling down (see Fig. ) and slack part of semi-rigid article Ropa 4, hanging on racks tilted inward.

At the initial moment after turning down the parts 5 or elements 17 and 18 due to the creation of planes inclined to the middle, the timber of the middle part of the package rushes down faster than the side parts, the movement of which is limited by the inclined planes of parts 5 (see Fig. 1) or elements 18 ( see fig. 3). This prevents the asymmetry of bag formation. The maximum elastic buckling of the package sections does not exceed the size of the gap between the area: the pieces of the down parts 5 or the elements 18 and the bottom part of the semi-rigid line 4 (when it is free from forest matirios).

The angle of rotation of the struts is chosen so that the lateral pull-outs of semi-rigid specimens are tensioned at an angle of 15 ° to the vertical, which is necessary for the correct formation of the bag.

The top straps are then pulled in and the bag is ready. The lugs of the sling are hooked up with the hooks of the cargo sling of the crane and the bag is lifted by the crane and the tank is carried into a stack or wagon.

When lifting the package, the stands, released from the load, rise to their original position up to the stop 11 by their own weight relative to axis 16 (see Fig. 1). it

5 occurs due to the shift of the center of gravity of the rack relative to the axis of rotation in the vertical direction.

In the second variant of the device (see FIG. 3), the racks are returned to the initial position

0 is implemented by springs 20.

In both cases, the legs are returned to their original position and fixed in it with the help of clips 6 by the action of the spring 10.

5 Then new revolving lines are hung and the cycle repeats.

In this way, it is possible to create a device for packing timber, in which all

0 conditions for the formation of a symmetric, equally dense package. This is facilitated by the possibility of simultaneous release of the racks from fixation.

Option device (smf.Z) with opera

5 for receiving timber, made of two elements 17 and 18, makes it possible to reduce the height of the device, to make it more compact, since the ends of the rotary elements 18 of the timber receiving bodies

0 is lowered all the way down to the base and the space under them is required less than in the first embodiment (see Fig. 1). The device is much simpler and less metal consuming than the known ones, primarily due to

5 lack of balances.

After removal of the finished package, it automatically arranges for the reception of new timber, which speeds up the packing cycle and facilitates the work of the staff.
