Description

The invention relates to storage equipment, namely, devices for the packaging of long products, such as sleepers, and can be used in the trellis workshops of timber industry enterprises and timber transshipment plants.

A device for packing piece goods is known, in which the bag forming mechanism is equipped with movable supports made in the form of two shelves mounted on rollers. When extending the supports, the formed row is lowered onto the frame 1.

It is also known a device for packing piece goods, which consists of a transverse conveyor and the stacker itself. A conveyor belt that supplies parts from the machine consists of endless belts that are pulled on the drum and equipped with additional pressure rollers. - The stacker itself consists of two receiving shelves, hinged together on a frame, hinged together, a latch and a movable cantilever, a slipway along the direction of it. The console bears on itself two hingedly reinforced shelves, fitted in the lower part with shaped bends, and is balanced by the weight with help of a cable thrown through block 2.

However, this device cannot be used for laying sleepers in transport bags. According to the technical conditions of transporting the sleepers, the upper row of the transport package should consist of n - 1 pieces of sleepers with n pieces in the remaining rows. In addition, overpacks are formed with a specific number of sleepers in a row depending on the type of sleepers, the shape and size of the cross section. The design of the well-known stacker does not allow the formation of a series of a certain number of parts, since the trees, the trees free up the shelves only after the row has been completely filled, and the number of parts in all the rows remains constant, i.e. it is not possible to form an upper row with a different number of stacked products. In addition, for the operation of the stacker, it is necessary to pre-sort the products stacked in the stack, not provided {1 on its design. The disadvantage of the known stacker is that the stack of piles is made directly to the cart, which must be constant; However, it is located in the stacker, which is inconvenient when there are a large number of them, since the delay in overloading the bags from the telokkn into wagons or warehouse. In the case when the unloading time exceeds the set time of one row, the stacker must be stopped to return the carriage for loading.

1 Deliveries are the formation of a package of products, mainly sleepers, and the requirements for transportation of broad gauge railways.

This is achieved by the fact that in the known device for packing long articles containing a frame on which the swiveling canopies of the lifting and lowering console cantilever are hinged: 1, Adki, the horizontal directions are mounted on the frame, in which the carriage is fitted, equipped with rigid and folding stops , and the visors are equipped with locks interacting through a joint-lever system with a carriage.

To form the upper row of the package, the folding stop has a roller through which a flexible body is slung, one end of which is fixed to the frame and the other end is connected to the counterweight.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the mechanism of formation of the series; in fig. 3 is a view along arrow A in FIG. one; in fig. 4 is a section BB in FIG. 2

The proposed device consists of a frame 1 with vertical guides 2 fixed along the edges along which the support pads 6 move with chains 3 through a common shaft 4 from the electric drive 5. In the upper part of the frame there are peaks 7 with locking lugs 8 and counterweights 9 .-.- pbKii are held in a horizontal position by locks 10, connected with each other by means 11. Through a lever-lever system, the locks are connected with the spring 12, and through a lanyard 13 - with a movable carriage 14. The carriage is mounted on a horizontal direction 15 and has a hard 16 and tkidnoy 17 stops. The rollers 18 are mounted on the carriage, the hinged support and the frame 18. The cable 19 is at one end rigidly fixed to the frame and stored through the roller carriage of the carriage, forming a loop on the hinged roller. Further, the cable is led through the system of rollers to the lower part of the frame, where its other end is fixed on the movable counterweight 20. The fj-prt of this carriage can be freely moved jfo) by the rail 15, regardless of the position of the folding stop. The palletizing mechanism has a platform 21.

 Sleepers are fed to the sorting table. The operator distributes them, depending on the type, breed, shape and size of the cross section, on packaged devices using commands (device and flag devices). As the plugs arrive, the dumping device M is fed from the sorting roller table to the visors 7. The visors through the locking stops 8 with the locks 10 are held in a horizontal position. The array is formed from five chips. Each subsequent pushes all previous ones. At the time of dumping the pin of the raft from the sorting roller of the rammer, resting against the rigid support 6, the carriage 14 is moved along the horizontal directional guide 15. When the carriage moves through the hinged-lever system, the locks turn and come out of the engagement with the stops 8. P the sleepers under their own weight are lowered onto the bearing pads 6 and release the fixed stop 16. The spring 12 returns the carriage 14 to its original position. When the last nipple of each row is supplied and the carriage 14 is displaced, the electric motor of the palletizing mechanism 5 is turned on, the shaft 4 and the chain 3 are set to rotate. In this case, the bearing pads 6 are lowered down to the height of the nippers. The drive shuts off when the carriage 14 returns to its original position. The synchronism of the visors and support sites is provided by a kinematic scheme.

The shaping of the next row may begin immediately after returning the carriage to the visor. The initial position of the carriage can be changed with the help of the lanyard 13, which makes it possible to form packages depending on the type, shape and size of the cross section, and the number of them in the row.

After the formation of the penultimate row has been completed, the support platforms 6 come into contact with the counterweight 20, which pulls the cable 19, along which the carriage with the roller of the hinged support 17 rolls, and the loop is pulled out. In doing so, the roller 18 is pressed upward and fixes the folding stop in a vertical position.

After the last row has been formed, the supporting platforms 6 stack the finished package on the platform 21, and lower themselves below.

0 Platform 21 automatically places the bag outside the palletizing mechanism; the electric motor reverses and the support platforms immediately return to the upper position, which ensures continuous operation of the device.

Stop of the pads in the top and

the lower position is provided with limit switches (not shown in the drawings). After the bag is unloaded by crane, the platform returns to the wrapping device.

0Application of the proposed device allows to automate the process of stacking in a package of rock products. Automation of the process is achieved with the help of a carriage, the hard stop of which serves to pick up all the rows, and the folding stop provides the set of upper

 p yes, i.e. allows you to create a package in accordance with the requirements for transport packages requirements. The presence of a lanyard in a hinged-lever system allows you to set the initial position of the carriage for

a package of a certain width. Performing support sites with a drive allows you to immediately lower the entire package onto a cart or platform with steps equal to the height of one row and pinch. Due to this, the process of recruiting a stack into a bag can be performed during unloading.

The use of a packetizer with sorting will allow mechanization of manual labor during the operations of sorting and stacking. in the transport package at 75-80%. At the same time, the expected economic effect from the introduction will be up to 3,500 rubles. in year. Claim 1.
