Description

The invention relates to a pallet loader for goods

in packages, and especially packages, bags or equivalent, grouped in different layers corresponding to the dimensions of the pallets, so that the goods are transferred by means of a conveyor belt on a table intended to receive them, arranged horizontally and serving as a transfer member and they are then deposited by this sheet, in layers, on a pallet placed i c8té of the sheet or on the layer

  of goods already on the pallet.

  For palletizing goods in packages or bags, automatic loaders are known which deposit the goods, turned according to size and format, in layers on the pallet. This is how a bag palletizing device is known which allows the stacking of bags on the pallets, forming a compact assembly, independently of the shape of the assembly chosen, device which transports the bags, by means of a conveyor belt and a slide movable vertically with respect to the direction of transport, which brings them onto a sheet intended to receive the packages,

serving as a transfer member, placed parallel to this conveyor belt

and then transhipping these bags on the pallet placed on a platform

mobile form up and down, platform which, after falling

  sée 3 the height of the bag, rises, each time a layer of bags is deposited on the pallet or on the layers already there, in the direction of a mobile t8le applying pressure, the underside of the t8le mobile intended to receive packages having a curved shape on the front, starting from the edges and going towards the middle of the t8le. A retaining bar placed in the opposite direction to the direction of removal of the sheet and therefore close to the outer edge of the stack is designed so that when the sheet is removed, it can put pressure on the upper layer of bags, so a transfer of the different layers of bags on the pallet is made possible, without

the layer of Gonstituated bags is destroyed (DE-AS 12 75 468).

Such palletizing devices for parcel goods, operating with a t8le intended to receive the packages, serving as a transfer member, have the drawback that the t8le intended to receive the packages is placed in the frame of the machine in the area of the working path of the pallets to be brought in and diverted so as to be movable in the vertical direction so that, when partially loaded pallets must come out of the loading area and a new pallet of another type must be introduced , this t8le must be lifted, using its support frame, so that the passage is free for the diversion of the first partially loaded pallet and for the supply of the second

  pallet, also possibly partially loaded. That's why he

  is necessary whenever an exchange of pallets or pallets per

  If the goods are loaded with different goods or different bags, the sheet intended to receive the packages is raised, so that it is not possible, during this process, to prepare a new layer of goods on the sheet. To this is added the fact that the sheet intended to receive the packages of the known devices for palletizing the goods can only be moved one side in the horizontal direction, so that the supply of goods to constitute a layer of goods on the ttle can

be performed only on one side. Likewise, the transfer of a layer of merchant-

  say t8le on a pallet or on the top layer of goods

  already on the pallet is only possible on one side.

  In addition, the known palletizing devices have the disadvantage that the different layers of goods must be grouped on the sheet (intended to receive them) itself or on a feed slide, inserted in front of this sheet, to can then be transferred from the sheet to the pallet to be loaded. One cannot reach

  high charger efficiency, since a new layer of merchant

  say can only be formed on the sheet again when the layer

  previous goods have been transferred from the t8le to the pallet.

  On the other hand, the aim of the present invention is to shout a palletizing device comprising a transformable tCle (intended to receive the goods), which can be put in the position of the pallet,

  tThe retractable in the vertical direction, which allows a trans-

  back of the pallet already carrying stacked goods, without it being

  necessary for this movement to lower the pallet and its steps

stacked candies or lift the sheet, to be able to bring the pallet

  to the package guide, under the horizontal conducting arms

  cantilever rate provided on known type chargers.

  To do this, the present invention provides a device according to the type described above, designed so that a horizontal support frame, placed in a frame of a machine with vertical guides, can be moved vertically by means of a mechanism. control, supporting frame

with two side telescopic brackets, actuated by a mechanical

  control or manually, of which the parts which can be unfolded

and retracted carry the sheet which is made mobile, thanks to the moving parts

the consoles and which can deposit a layer of goods on the pallet or on the upper layer of goods already on the pallet and which can remove partially loaded pallets of goods from the loading area or those which are fully loaded. With a pallet loader arranged in this way, with a foldable and horizontally retractable sheet, it is possible to have the loaded pallets of the loader transversely displaced, so that this transverse movement of the loaded pallets is not necessary. lower the pallet or lift the tCle. If a pallet partially loaded with goods in packages has to leave the loading area, so that another pallet partially loaded with goods of another type can be brought in, it is sufficient to return the sheet metal to the frame of the machine, c that is to say in the vertical direction, so that partially or fully loaded pallets can be brought without obstacles into the loading area. The

fact that it is not necessary, for the replacement of partial pallets-

Lement loaded, lifting the t8le already prepares a layer of goods on the t8le during the movement of the partially loaded pallet, so that a pallet loader thus arranged allows to obtain a high work efficiency. If the sheet is formed so as to be unfolded and folded on both sides, it is also possible to prepare layers of goods in turn, which are then brought to the corresponding pallet on one or the other. other side of the charger. In this way it is possible to load pallets with goods

  sorted by sort, which is particularly favorable when goods

  say different sizes must be grouped in different layers or when it is, for example, bags of different contents, so that the bags of the same content can be directed to the same pallet, while

  that bags of other content are brought to another pallet.

In order to be able to load goods in packages on a loader having such an output, the invention further provides the possibility of

space-saving storage of a number of layers of prepared goods.

  which can be resumed at any time. According to the invention, a device

tif pallet loader with the possibility of storing layers of goods

  say maybe. at all times taken up is designed so that a horizontal support frame, placed in a machine frame with vertical guides, can be moved vertically by means of a control mechanism, support frame with two lateral telescopic consoles, actuated by a control mechanism or manually, whose parts which can be unfolded and retracted carry the sheet which is made mobile, thanks to the mobile parts of the consoles and which can deposit a layer of goods on the pallet or on the upper layer of goods are already on the pallet and take out the partially or fully loaded pallets

2 2464903

  loaded with layers of goods from the loading area and only available

  storage of goods rearranged in layers before their transfer

on the t8le is provided, device comprising a slide for feeding the

  candles, at least two storage paths located one above the other, at a certain distance from this slide, and a transfer device located between this slide and the two tracks, device being shaped as

a rotating roller conveyor, or as a rotating conveyor belt

tive, the end of which is located on the side of the merchant

  say, in the area of the goods supply slide, itself provided with a slide bar leading to the transfer device pivots about a horizontal axis, while the other end, located on the unloading side goods, pivots by means of a control mechanism

  in the area of the various storage routes.

  With a loading device arranged in this way, it is possible to operate pallet charmers for goods in packages and bags, obtaining a high work efficiency, because the layers of goods prepared on the storage lanes can be, at any moment,

times or summer by the charger. During the transfer of a layer of mar-

  from the t8le for packages to the pallet, the free storage path can already be filled with a layer of goods, so that it is possible, alternately, to withdraw and bring, by means of the tale of

loader, the layers of goods that are on the storage routes

ge. The use of such a storage station makes it possible to obtain, with this charcher, high yields. If, in addition, the storage routes are formed

  like package sheets, horizontally movable, the char-

  pallet feeders have the possibility of using, for the transfer of

layers on the pallet, of these sheets, formed as storage routes.

In this case, the loader does not have a packet size. The differences

  your sheets with layers of goods are then seized by the

  loader and taken to the pallet area to be loaded.

  Other favorable arrangements of the invention result from

subclaims.

The pallet loader, represented by FIGS. 1 to 3, comprises a machine frame 10, with four vertical guides 11, 12, 13 and 14 which are placed in the corners of the square or rectangular base surface of the machine frame 10 A horizontal support frame 20 is held in these guides 11 to 14 profiles, so as to be able to move in the direction of arrow X. This support frame 20 is provided, on the board, with guide rollers 21 which are located in guides 11 to 14. In addition, the carrying frame 20 is connected, for vertical movement in the direction of arrow X, in the btti

  machine 10, has a control mechanism 22 which actuates the trans-

mission indicated by the reference 23, connected to the supporting frame 20 (Figure 1).

  The support frame 20 is provided with two horizontal and lateral brackets 30 and 35, located at a certain interval from each other, which comprise telescopic segments. For the form of examination illustrated in FIG. 4, each console 30 or 35 of the carrying frame 20 is composed of a fixed segment 31 or 36 and of a self-folding and retractable segment,

that is to say mobile, 32 or 37. The two segments -32 and 37 can be esca-

  motable and extendable in the direction of the arrows Xl. To lead the segments

console 32 and 37 to console segments 31 and 36, fold-out guides

  ble 33 and 38 are provided, which connect the console segments 31 and 36 to the segments 32 and 37 in such a way that, when the segments 32 and 37 are unfolded, the guides 33 and 38 also unfold and simultaneously have an effect

of stabilizer on the whole arrangement.

The configuration of the telescopic segments 30 and 35 represents

  shown by Figures 3 and 4 allows the free movement of the movable segments 32 and 37 in both directions. In this way, it is possible to unfold the console segments 32 and 37 either to the left or to the right of the

machine frame.

  Unfolding and retracting console segments 32 and 37

  can be carried out manually or using a control mechanism 50.

For manual actuation of the segments 32 and 37, control levers - which are not shown in the drawing - are provided, at the free ends of the segments 32 and 37 so that it is possible to unfold or retract effortlessly segments 32 and 37 (or unfold and unfold them

retract alternately).

  If, however, a control mechanism 50 is provided for the unfolding and retraction of the segments 32 and 37, that consists, according to the embodiment shown in FIG. 2, of a continuous transmission cable 53, controlled at- above this control mechanism and driven above the guide rollers 51 and 52, mounted on the fixed segments 32 and 36. The lower end 53a of the continuous transmission cable 53 is connected above the towing cable 54 in such a way to the two segments 32 and 37 that, during a circulation of the transmission cable in the direction of the arrow X2, the two segments 32 and 37 can be unfolded laterally (FIG. 2). The retraction

console segments 32 and 37 in the starting position can be performed

  killed by means of tension springs not shown in the drawing; it can also be performed by reversing the direction of circulation of the cable.

  transmission 53, the console segments 32 and 37 being connected to the lower end

link 53a of transmission cable 53.

  However, the supporting frame can also be provided with telescopic brackets 30 and 35 formed in another way. It is essential that the brackets 30 and 35 are provided with segments which can be unfolded and retracted, so that they can be retracted into the area of the machine frame 10. (FIG. 5) The two segments 32 and 37 - which can be unfolded and retracted - consoles 30 and 35 of the carrying frame 20 carry a sheet for parcel 40, above which the two segments 32 and 37 are connected to each other. If the two segments 32 and 37 are in 4-sided profiles or in profiles with straight edges, the sheet 40 is fixed to each of the surfaces of the profiles located on the c8t; of the ground. The size of the tCle corresponds to the size of the layers of goods (in packages) to be formed, and this, by adjusting to the size of the loading surface of the pallets used, so that the different layers of goods made up on the t8le can be, for an adequate working mode of the loader, transferred on a pallet

  indicated by P in Figures 4 and 5.

  If the supporting frame 20 with the sheet LO is constructed of the

  as shown in Figure 3, the t8le 40 can be unfolded side-

ment out of the machine frame 10 in both directions, by means of segments 32 and 37, and this, in the direction of the arrows X3 and X4. If, however, another configuration of the telescopic brackets 30 and 35 is provided, it is possible to arrange the t81e 40 on the two brackets 32 and 37 so that the

  sheet fixing is carried out at the two free ends before seg-

  mobile elements 32 and 37, while the other ends of the sheet 40 slide

  feels on the fixed console segments 31 and 36, so that when climbing

drive segments 32 and 37 with the sheet 40, it can roll on the fixed segments 31 and 36, using rollers not shown by the design The two brackets 30 and 35 are, however, for this form of execution, so distant from each other that, after having been unfolded laterally, the sheet

can be raised on the pallet or on the upper layer of goods

  its, so that the console segments 32 and 37 located on the side of the t8le 40 come to rest on the side of the pallet or layers of goods already on the pallet and that they cannot therefore generate no way the process of transferring the layer of goods from the

t 40 on the pallet.

For the transfer of a layer of goods from the tl81e 40 onto the pallet P, a retaining bar 45 is provided in the machine frame, bar lowering in the zone where the layer of goods is located on the sheet 40 , so that the layer of goods cannot be destroyed, when removing the sheet from the layer of goods in the direction of arrow X5, but on the contrary that it is placed on the pallet in compact block ( figure L). This retaining bar 45 is designed so that it can be raised and lowered, this using the control mechanisms not shown in the drawing, so that it is raised, for the transfer of a layer of goods oe the tale 40 on the pallet and that

  is then raised when the t8le is returned to the charging position -

  ment in the machine bed 10 then moved with a new layer of goods to the unloading position o The bringing of different goods in order to constitute different layers of goods on the t81e can be carried out using a slide supply of goods 220 with or without the insertion of a storage device 200 described more precisely below (FIG. 6) The machine frame with the carrying frame 20, the telescopic brackets 30 and 35 and the tCle 40 for packages form , in their whole,

8 2464903

  the pallet loader designated in FIG. 1 by the reference 100 and which operates as follows: Goods such as packages or bags are brought to the pallet loader 100 by the goods supply slide 220, the different layers of goods being either grouped at the other end of the supply slide 220 or else prepared on the t8le 40, tCle which is, in the latter case, lowered in the machine b 10 10 so low that a transfer of the goods can take place in the direction of arrow Y1 using a transfer bar 221 (Figure 6). If a layer of goods is prepared on sheet 40 or if a layer of goods already prepared has been transferred to sheet 40, the supporting frame 20 with sheet 40 and the layer of goods therein is raised very high, up to 'the tCle stops, above the pallet to be loaded, itself located next to the machine frame 10 or above the upper layer of goods already on the pallet. In this position of the frame 20 with the tCle 40, the tCle will develop laterally out of the machine frame above the pallet P so as to stop at a small interval above the pallet P or the top layer of goods lying on a stack on the pallet. When the tSle 40 has taken this positbon, the retaining bar 45

  lowers. The retaining bar 45 sticks to the lateral edge of the cover.

Che of goods located on the t8le 40, after which the t8le entered the machine frame 10, in the direction of the arrow X5 by means of the consoles

telescopic 30 and 35 (Figure 4). During this withdrawal from t8le 40, the

Che goods on the tale is placed on the pallet P. When the transfer process is complete, the tMle 40 takes the position indicated in Figure 5 and a new layer of goods can be charoée. If, for the goods which have already been placed on the pallet, packages and if, now, bags must be loaded on the pallet, the pallet P loaded with packages will move in the direction of the arrow X6 laterally with respect to the vertical working path of the tle in the machine b and ti and a new pallet is brought into the unloading area. If, now, a layer of bags has been prepared on the sheet, the t8le 40 is brought above the pallet, in the same way as it was described above, and after the retaining bar 45 is lowered, the tCle 40 is returned to the machine frame 10 in the direction of the arrow X5, the layer of bags being simultaneously deposited on this pallet. Of this

  way, it is possible to transport pallets in the loading area.

your carrying marcnanoises each time different and depositing on the corresponding pallets the kinds of goods, in the form of layers of goods, which are intended for the different pallets. This is how it is possible to load sorted goods on the different pallets

by kinds.

  To have available the necessary quantity of layers of goods required to achieve a high working efficiency of the pallet loader 100, a storage device 200 is provided between the pallet loader 100 and the goods supply slide 220, after another embodiment of the invention. This storage device 200 is arranged

  in the machine btti 10 which accommodates the goods supply slide

  its 220, sliding horizontally, a slide which can be arranged as a conveyor with rotating rollers or as a continuous rotary conveyor belt, The direction of supply of the goods to be grouped in layers is that indicated by the arrow Y. At the end of the slide

  inlet 220, a stopper 222 is provided. A transfer bar 221 is in or-

  be provided, in the area at the end of the supply slide 220, bar capable of moving in the direction of the arrow Yl, by means of a control mechanism not shown in the drawing and used for transferring the layer of goods constituted on the supply slide 220 on a transfer device 240, connected to the supply slide 220. The direction of movement of the transfer bar 221 is transverse to the direction of arrival of the

goods (Figure 6).

  The end 2h1 of the transfer device 240 connected to the supply slide 220, which is located on the loading side of the goods, housed in the machine housing 10, pivots around a horizontal axis 245 so that the end 242 of the transfer device 240, which is located on the side

  unloading, pi-vote in the direction of arrow Y2. The pivoting of the dispo-

  transfer agent 240 around the pivoting axis 245 takes place using a

control mechanism 246.

  The transfer device 240 is arranged as a conveyor

  243 rotating roller or as a continuous rotating conveyor belt

  naked, so that the layer of goods formed at the end of the supply slide 220 can be brought in the direction of the arrow Y3 to

  storage tracks on the supply slide 220, which connect to the dispo-

transfer device 240.

  As regards the exemplary embodiment represented by FIG. 7, two storage channels 230 and 330 are arranged one above the other, at an interval, the distance separating the two storage channels 230 and

  330 corresponding at least to the height of a layer of goods.

  Each storage channel 230 and 330 is arranged in the machine frame 10

2464903

  in the direction of the arrow Y4 or Y5. and is movable in height so that

  layers of goods of different heights may also be available

  placed on the lowest storage channel 230. The oscillating movement of the transfer device 240 takes place by adapting to the position of each of the storage channels 230 and 33G in the machine frame 10.

  Each storage channel 230 and 330 is arranged as a trans-

  roller carrier. However, it is also possible to give each storage path the shape of a floor or a sheet (for packages) that can be moved horizontally. The dimensions of the storage lanes 230 and 330 are designed

  1G so as to correspond to the size of the layers of goods to be deposited.

  If the storage lanes 230 and 330 are designed as roller or floor conveyors, transfer devices 231 and 331 are provided for the transfer of the layers of goods from the storage lanes to

  the t8le for parcel 40 of the pallet loader 100, devices which cépla-

  hundred in the direction of the arrows Y6 and Y7 C using control mechanisms

  not shown in the drawing, so that the layers of goods available

  sées on the storage channels 230 and 330 can be transferred to the t8le 40 of the charger 100. If, on the other hand, the storage channels 230 and 330 are themselves designed as tCles that can move horizontally, the carrying frame 20 of the loader 100 has devices to grab these ttles, which are then removed from the corresponding fixings provided in the machine frame 10 and transferred using the carrying frame 20 to the area where the pallet to be loaded P. pivoting axis 245 of the transfer device 240 should preferably be arranged on the plane between the two storage channels 230 and 330, so that the transfer device

  should not perform too large oscillations.

  The number of storage routes need not necessarily be limited to two. A higher number of storage lanes arranged

  one above the other can also be provided. The transfer device 240 is then designed so that the transfer of the layer of

  goods prepared on the supply slide 220 on the different

  Storage routes are possible, without any disturbance.
