The installation for wrapping the film 1 of the bottomless stack 2 of the bags 3 comprises a device 4 for stacking the bags, a device for putting on the film case 5 on the stack 2, a device for feeding and applying the tape film 1 on the top layer of the stack 2 and joining it to the case 5 containing welding-separating device 6, stock roller 7 and device 8 for separating part of the film 1, device 9 turning the stack 2 by 180, heat-shrinking device made in the form of ring nozzles 10 arranged one above the other and at least There are two oppositely arranged rods 11 for shaping the contour of the film case 5 corresponding to the contour of the stack 2. At the same time, the rods 11 are installed with the possibility of adjusting their height. The devices 12 for clamping the hanging ends of the tape film 1 to the cover contain movable rollers (not shown) or compressed air supply nozzles 10 and a cooling device. The installation contains a piling conveyor 13, made, for example, in the form of a roller table and consisting of individual sections. The palletizing conveyor 13 serves to move the individual bottomless piles 2 bags 3, packaged in: Lenko 1, into the area of operation of the device and installation devices for carrying out individual packaging operations. The portions of the piling conveyor 13 have independent drives and a casing, its control device (not shown). The device 4 for stacking the bags 3 comprises a conveyor 14 for feeding the bags 3 with a pivoting device 15 for measuring the direction of movement of the bags 3 along the conveyor 14, a hopper with a transfer plate 16 installed with horizontal movement and a packaging stand 17 that is installed with the possibility of horizontal and vertical displacements. In the area of alignment of the piles 2 on the conveyor 13 in the upper part of the frame 18 is placed a roller 19 of the reserve of film 1 with a device (not shown) for measuring, cutting and laying the film 1 on the top and side parts of the stack 2. Behind the piling conveyor 13 there is a device for donning film the cover 5 on the stack 2, containing the stock roll 20 of the film 1, the guide rollers 21 having a pair of clamping pads, the device 22 for gripping the film 1, a shaped wedge part for opening the film 1 located in the upper part of this device (n shown), welding-separating device 23, device 24 for controlling the lateral edges of the film 1. The film 1 placed on the roller 20 has a tubular shape and is folded in such a way that in the central part of the cross-section is placed in two layers x - in four, with two central side layers formed by the side surface of the tubular film 1. The device 22 for capturing the film is adapted to allow vertical movement and movement of the clamping pads along the side surfaces of the cover 5 (not shown). Behind the piling conveyor 13 in the casing 25 there is a heat shrinking device with double doors (not shown). The annular nozzles 10 on the carrier frame are vertically displaceable and have separate switches (not shown). In another design (Figures 4 and 5), the heat-shrinking device includes a drive welding tip 27 vertically mounted for movement in an annular guide 26 and a pressure rod 28 fixed at an angle ahead of the tip 27, so that the distance between their upper ends is larger, than between the lower. The rod 28 is provided with pinch rollers (not shown). The spring-loaded pressure rollers 29 are placed on the support frame 30 and serve to form the longitudinal side grooves 31 in the cover 5 in the form of a stack of 2, containing a reduced number of bags 3 for inserting the forks of the respective lift (not shown). The rods 11 are mounted with the possibility of oncoming movement and are shaped in shape. stack of bags. The device 9 for rotating the stack through 180 ° contains supporting devices 32 for introducing into the recesses 31 of the cover 5, which is not put on the stack 2. The cooling device is a source 33 of cold air placed above the conveyor 13, the final portion of which serves to accumulate and ship the stacks of bags packed in the film. The installation works as follows. In the bagging device 3, the individual bags 3 are transported along the conveyor 14 in direction B and to the accumulator of groups of bags. With the help of the COW.PORT fixture 15, the longitudinally flowing bags are transferred into. the transverse position to obtain the bag layer 3. The groups of bags 3 formed in the accumulator and the prepared individual layers of bags 3 are transferred by means of the transfer plate 16 to the packing table 17 by shifting the transfer plate 16 in direction B to transfer the layer of bags 3 from the bag groups 3 to the packing table 17, the latter is displaced in height by such a distance as the accumulator of groups of bags 3 is located, which, for example, can be made in the form of a roller table. Separate groups of bags can remain on this bag group accumulator, which, after a corresponding transfer to the packing table 17, form separate layers of bags on the latter, however, individual layers of bags can be made already on the accumulator of groups of bags; 3. As soon as a bagging layer is placed on the packaging table 17, the packaging table is lowered to the conveyor 13 located in its lower zone. By displacing the packaging table 17 in direction B, the layer of bags 3 is transferred to the conveyor 13 or to the uppermost layer of bags already composed partly stack 2. If several layers of bags are already combined into one stack, then on the top layer of bags 3 itself another layer of bags 3 is placed, which is an auxiliary pallet and thereby creates the supporting surface of the f course by the stack 2 of bags 3 (FIG. 8). However, this layer of bags 3, compared with other layers of bags of finished stack 2, has a reduced area, so that two openings 34 are formed on two opposite sides of this bag layer. Composed using the device 4 for stacking the cages 3, separate piles of 2 bins 3 are placed on the piling conveyor 13 in such a way that free openings run parallel to the longitudinal direction of the palletizing conveyor 13 (Fig. 7). Device 4 for stacking bags is adjoined by a device for applying a covering film on the top, forming the bearing surface of stack 2 of bags 3, layer of bags 3. This device consists of stacking conveyor 13 located in the zone over the path / movement of individual piles 2 of bags 3 inserted into frame 18 roller 19 with a reserve of film 1, which is equipped with devices for unwinding the cover film of the desired length. Then the film is cut off and laid on the stack 2. The size of the cover film 1 is chosen so that it extends along the edges beyond the side surfaces of the stack 2 of the bags 3 (Fig.1.8).
    51279
    Then, on a piling conveyor, the stack 13 stacks 2 enter the zone of operation of the device for putting on the film sheath 5. A strip of film 1 is guided through the guide rollers 21 located in the frame 18 from the stock roller 20 to the zones in which the film sheath is put on the stack of 2 bags 3. The free end of the strip of film 1 is then pulled over the stack of bags 3. The gripping device 22, having a pair of clamping pads, picks up the edge of the free end of the strip of film and lowers it into a vertical drive (not shown) m direction to the conveyor 13, and at the same time the gripping devices 22 are spread, in the lateral zone of the stack of bags 2 provided with a film cover 5, the film 1 receives the spread and is put on over the headquarters; {2 bags 3. The film is opened by means of a shaped in the upper part of the device wedge detail
    Slip the strip of film 1 over the stack of 2 bags and then cut them off using a welding-separator 23 and at the same time connect the welding stitch in the cut area so that this section of the film strip closes on top and surrounds the bag-shaped stack 5. As soon as it is equipped with a film cover 5 the bag stack leaves the area of operation of this device, the gripper device 22 is moved to its upper position to work with the next stack.
    For a high-quality, smooth supply of the strip of film 1 through the bound stack of bags on the frame 18, the device 24 is provided for controlling the boom edges of the boot 5.
    Due to the fact that the roller 20 with the reserve of film 1 is placed on top of the path of the stack of 2 bags 3, the strip of film 1 should be guided only in a short vertical segment, so that the 24 l side edge control device also needs only a short range of movement. Thus, it is possible to reliably and accurately feed a strip of film 1 to a stack of bags 3 provided with a film cover 5.
    Then, a stack of 2 bags 3 provided with a film case 5 enters the heat-shrinking device made in the form of a casing 25. During the shrinking process, both of its double-leaf doors are closed. I After entry, it is wrapped in a film case. 5 piles of bags 3 into the internal volume of the casing 25, the annular nozzles 10 are lowered so that a comprehensive shrinkage of the film cover 5 occurs due to heating. The annular nozzles 10 are activated one at a time, all at once, or select any appropriate number of annular nozzles from the height of the film cover 5 by connecting nozzles one by one, to obtain the desired amount of heat, for shrinking - hot crimping of a given size of the film cover 5.
    In another design, the heat-shrinking device (Figures 4 and 5) consists of a stack of bags placed over the path and a ring-shaped guide 26, which is hung to a vertical welding tip 27 for flame welding, which is rotated by means of the drive unit in the direction C. This heat occurs through a weak flame coming out of the tip 27, acting on the film 1. The ring guide 26 is installed so that the welding tip 27 when passing its almost circular path always has the same interval from the outer surface of the walls of the film cover 5 or stack of 2 bags 3.
    In order to prevent the film cover 5 and the surface of the stack of 2 bags of air 3 from accumulating, the clamping rod 28 is suspended on the annular guide 26, which has a certain angle of inclination relative to the welding tip of the flame syarke, so that the lower free end of the rod 28 and the welding tip 27 are less than the distance between the upper end of the rod 28 and the tip 27. The rod 28 is made leading in relation to the tip 27 in the direction of the arrow (Fig. 4). This rod 28 has a series of spring-loaded pressure rollers that press the film case 5 to the surface of the side walls 7127 of a stack of 2 bags 3, which is collected between the film cover 5 and the surface of the side walls of the stack of 2 bags of air from the flame heating area. Especially advantageous is the inclined position of the rod 28 to such an extent that the last air residues from the cavity between the film cover and the side surfaces of the stack 2 can be squeezed to ensure uniform shrinkage of the crimping of the film of the cover 5 in all areas. After exiting the casing 25, the stack of 2 bags is applied at the end section J5 of the conveyor 13 to the pressure rollers 29 to form the longitudinal side grooves 31. Due to the covering film on the portion of the supporting surface of each stack of bags before applying the film cover 5 using the rollers 29 of the recesses 31 (the supporting surface of each stack) in these areas, a multi-layer film coating is obtained, so that the most loaded sections of the stack 2 are repeatedly protected. The shaped rods 11 by trechnogo allow movement before cooling the heated and seated (the compression) of the film cover 5 to fit it. the contour of the sidewall surface of the stack of 2 bags 3. Due to the presence of separate layers laid one on another, each stack of 2 bags 3 has a characteristic contour in its perimeter of the wall surface, which especially depends on the retracted portions between the heads or sides of the bags of two lying one on another layer; bags; After the withdrawal of both rods 11, the seated film sheath has an outline of the surface of the side walls of the stack of bags. After cooling. The NIN of the seated film thus produces a stack of bags of the highest strength, which is especially advantageous when the stack of bags consists of such bags in which material with high fluidity and flowability is placed. In this way it is possible to obtain in itself a very strongly bonded stack of bags bound into a film shell. 4 Since the stack of 2 bags has so far moved on the piling conveyor 13 with the auxiliary pallet lying at the top, it is now necessary to rotate the stack 180 in order to be able to cover the not yet protected section of the film 1. The rotation of each stack of bags is carried out in the feed direction of the stack of 2 bags 3 so that, also after the end of the rotation operation, the stack of bags is. Forces are placed on a conveyor belt, with recesses 31 extending parallel to the longitudinal direction of the conveyor 13. Head, recesses 31 are inserted. Supporting devices that can be made, for example, in the form of support beams, etc. (to avoid shear bags). When the stack of bags is rotated 180 and installed on the conveyor 13, this stack of bags is transferred to the area of the device for applying a tape film on the top layer of the stack and connecting it to a case in which the roll 7 with a reserve of film 1 is installed up the movement path of the stack 2, where with the help of appropriate devices each time unwind the laid length of the film. By means of the device 8 for separating a part of the film, the unwound length of the film is cut off from the film strip on the stock roller 7. The coating film used has an increased surface area compared to the film layer forming the notches 31, so that the coating film partially overlaps the surfaces of the side walls of the seated film sheath by its extreme sections thus 5. When the coating film is applied to the stack of bags by local heating the cover film is welded to the cover 5 so that the entire cover 5 / is not subjected to new heating. In order to bring the outermost part of the coating film to the sheath 5, the device 12 is pressed into operation to press the hanging ends of the film 1 and the lateral protruding sections of the sheeting are pressed to the seated film sheath by supplying compressed air. - / by the combination of mechanical devices, by means of spot welding, Only after pressing 12 on the side of the protruding or hanging sections of the tape film to the seated film cover, is the actual loading EV, shrinkage and crimping of the coating film. After exiting the device 9 of rotation of the stack 2, the bags 3 are supported by means of devices inserted into the recesses 31 until the film is heated. The devices are placed on both sides of the piling conveyor 13 and can be constructively made as roller conveyors that are placed over the piling conveyor 13. Thus, the sheathed cover 5 of the pile 2 of the bags 3 to its removal from the installation or to the cooling of the heated and seated cover film gets such an anchor pad on fig.Z
    Fmg.Ts410 section of its bottom, which prevents the deformation of the stack. In its end portion, the stacking conveyor 13 is used as a storage device for ready-to-packaged film stacks of bags and from which individual stacks of bags can be removed using appropriate devices (not shown). In order to cool and press down the (seated) coating film to cool faster, they include a cooling device made in the form of a source 33, the latter being brought to the surface of the packaged stack 2. The invention improves the quality of the package by forming a multilayer sheath in the areas of greatest load on the packaged stack 3029. .12
