Description

L3ZY 2473021

  The invention relates to a pallet loader designed for j package goods, and especially packages, bags or the like, I grouped in different layers corresponding to the dimensions of the pallets, so that the goods are transferred by means of 'a band :; conveyor on a sheet intended to receive them, arranged horizontally and serving as a transfer member and that they are then deposited by this' ttle, in layers, on a pallet placed next to the sheet or on the layer

  of goods already on the pallet.

  For the palletization of 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 bags to be stacked on the pallets, forming a compact assembly, regardless of the shape! of the chosen assembly, 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

  ! seated at 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 movable plate applying pressure, the underside of the tBle mobile intended to receive packages having a curved shape on the front, starting from the edges and going towards the middle of the sheet. A retaining bar placed, in the opposite direction to the direction of withdrawal of the sheet and therefore close to the outer edge of the stack is designed so as to be able, when removing the sheet, to put pressure on the upper layer of bags, if although it is possible to transfer the different layers of bags to the pallet, without

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

  30. Such devices for palletizing goods in packages, * operating with a t8le intended to receive the packages, serving as a transfer device, have the drawback that the t8le intended to receive the I packages is disposed in the frame of the machine in the area of the work path - pallets to be brought in and diverted so as to be displaceable in the vertical direction so that when partially loaded pallets X have to come out of the loading area and a new pallet of another type must be introduced, this t8le must be lifted, using its carrying frame, so that the passage is free for the diversion of the first partially loaded pallet and for the supply of the second

2473021-

  | pallet, also possibly partially loaded. Therefore, it i

  is necessary whenever an exchange of pallets or pallets per

  partially loaded with different goods or different bags takes place, to raise the tale intended to receive the packages, so that it is not

  possible during this process to prepare a new layer of merchant

  say on the phone. To this is added the fact that the t8le intended to receive the packages of the known devices for palletizing the goods is X movable only on one side in the horizontal direction, so that the supply of goods to constitute a layer of goods on the t8le 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 t8le (intended to receive them) itself or on a supply slide, inserted in front of this tale, so that it can then be transferred from the t8le to the pallet to be loaded. One cannot reach;

  a high efficiency of the charger, since a new layer of merchant-

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

  previous goods have been transferred from tMle to pallet.

  On the other hand, the aim of the present invention is to create a palletizing device comprising a sheet metal (intended to receive the goods) which can be transformed, which can be put in the position of the pallet

  | f t8the 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.

  Oi It 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 machine frame with vertical guides, can be moved vertically by means of a operating mechanism, support frame

  with two side telescopic brackets, actuated by a mechanical

  P5 me control or manually, of which the parts which can be unfolded

  j {l and retracted carry the t8le which is made mobile, thanks to the moving parts

  i I 'the consoles and who can deposit a layer of goods on the pallet or on the upper layer of goods already on the pallet and- who can take out partially loaded pallets of: 40o goods from the loading area or those that are completely _ _ _ t_ _ __ - .- i loaded. With a pallet loader arranged in this way, with the foldable and retractable t8le horizontally, it is possible to place It across the loaded pallets of the loader, so that it is not: necessary for this transverse movement of the loaded pallets, lower the pallet or lift the table. If a pallet partially loaded with goods in packages must leave the loading area, so that another pallet partially loaded with goods of another type can be brought, it suffices to return the sheet in 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 tale 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 to be unfolded and folded on both sides, it is also possible to prepare layers of goods in turn on the sheet, which are then brought to the corresponding pallet of 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 of different sizes should be grouped in different layers or when it is, for example, bags of different contents, so that * bags of the same content can be directed to a 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 also provides for the possibility of

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

  - items which can be resumed at any time. According to the invention, a. disposi-

  : tif pallet loader with the possibility of storing layers of goods

  dises can be taken at any time 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 side telescopic brackets , actuated by an e35 'control mechanism or manually, the parts of 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 layer of goods already on the pallet and take out the partially or fully loaded pallets! . i

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

  storage of goods grouped in layers before their transfer

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

  trays, 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 where the merchants are

  say, in the area of the goods supply slide, it itself has a slide bar leading to the transfer device pivots about a horizontal axis, while the other end, located on the i side of the - unloading of 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 maneuver pallet loaders for goods in packages and bags, obtaining a high work efficiency, because the layers of goods prepared on the storage lanes can be removed at any time. ,

  taken back or removed by the charger. During the transfer of a layer of mar-

  candies - from the sheet 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 charger t8le; the layers of goods that are on the storage lanes. The use of such a storage station makes it possible to obtain, with this charger, high yields. If, in addition, the storage channels are formed

  like package sheets, horizontally movable, the char-

  pallet feeders have the possibility of being used, for the transfer of

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

  In this case, the charger does not have a packet t8le. The differences

  your tales 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 bSti 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 side, 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 the arrow X, in the frame

  of machine 10, 3 a control mechanism 22 which actuates the transmission cable

  mission indicated by the reference 23, connects to the support frame 20 (Figure 1).

  The carrying frame 20 is provided with two horizontal brackets i: and lateral brackets 30 and 35, located at a certain interval from each other, which i comprise telescopic segments. For the embodiment illustrated in FIG. 4, each console 30 or 35 of the support frame 20 is made up of: 259 fixed segment 31 or 36 and a self-folding and retractable segment,

  ! i.e. mobile, 32 or 37. The two segments 32 and 37 can be esca-

  m motable and extendable in the direction of the arrows XM. 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 j 37 are unfolded, the guides 33 and 38 also unfold and simultaneously have an effect

  I XI of stabilizer on the whole arrangement.

  The configuration of the telescopic segments 30 and 35 represents

  fée by Figures 3 and 4 allows the free movement of the movable segments 1359 I 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.

  fjl Unfolding and retracting console segments 32 and 37

  can be performed manually or using a control mechanism 50.

  For manual actuation of segments 32 and 37, control levers 1 - which are not shown in the drawing - are provided at the free ends 51 of segments 32 and 37 so that it is possible to unfold or d '' easily retract segments 32 and 37 (or unfold them and ''

* i! retract alternately).

  If however a control mechanism 50 is provided for the unfolding and retraction of the secments 32 and 37, that consists, according to the embodiment shown in FIG. 2, of a continuous transmission cable 1 53, controlled above this control mechanism and driven above i '' of 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 tractor cable 54 in such a way as to the two segments 32 and 37 that, during an i - j circulation of the transmission cable in the direction of the arrow X2, the two i 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 done by reversing the direction of flow of the cable

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

  , front 53a of the transmission cable 53.

  However, the support frame can also be provided with telescopic brackets I i 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 in the area of the machine frame 10. (FIG. 5) retracted - from the two segments 32 and 37 - which can be unfolded and X * retracted - consoles 30 and 35 of the support frame 20 carry a t81e 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 3 straight edges, the t8le 40 is fixed to each of the surfaces of the profiles located on the side of the ground. The size of the t8le 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 l | to be, for an adequate working mode of the loader, transferred to a pallet

  i indicated by P in Figures 4 and 5.-

  | I If the supporting frame 20 with the tSle 40 is constructed of the

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

  i ment out of the machine bttl 10 in both directions, by means of the segments 32 I 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 t8le 40 on the two brackets 32 and 17 so that the

  the t8le is fixed at the two free ends before seg-

  mobile parts 32 and 37, while the other ends of the tCle 40 slide

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

  drive segments 32 and 37 with the plate 40, it can roll on the

  fixed segments 31 and 36, using rollers not shown in the drawing.

  The two brackets 30 and 35 are however, for this embodiment, so distant from each other that, after having been unfolded laterally, the tsle

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

  ji ses, 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 therefore cannot generate * .1 in any way the process of transferring the goods layer from the

j tble 40 on the pallet.

  For the transfer of a layer of goods from the t8le 40 onto the pallet P, a retaining bar 45 is provided in the machine frame, bar lowering in zone A is the layer of goods located on the tCle 40 so that the layer of goods cannot be destroyed when the sheet is removed from the layer of goods! 25i in the direction of arrow X5, but on the contrary that it is placed on the pallet in compact block (figure 4). This retaining bar 45 is designed from! i so that it can be raised and lowered, using i i i | control not shown in the drawing, so that it lowers, for transferring a layer of goods from the t8le 40 onto the pallet and

  301 is then raised, when the t8le is returned to the load position -

  ment in the machine b 10 then moved with a new layer of

  goods in the unloading position.

  The bringing of different goods with a view to constituting different layers of goods on the t8le can be carried out using a slide for bringing goods 220 with or without the insertion of a

  storage device 200 described more precisely below (FIG. 6).

  I | The machine frame with the carrying frame 20, the telescopic console t4i I 30 and 35 and the parcel plate 40 form, as a whole, i I the pallet loader designated in FIG. 1 by the reference 100 and which I operate as follows: l Q Goods such as parcels or bags are brought to the pallet loader 100 by the goods supply slide 220, the

  51 different layers of goods being either grouped together at the other end

  mite from the feed slide 220 or prepared on the t8le 40, tCle which is, in the latter case, lowered in the machine frame 10 so low that a transfer of goods can take place in the direction of arrow Y1 using a transfer bar 221 (Figure 6). If a layer of goods! oi is prepared on the tale 40 or if a layer of goods already prepared have been transferred to the t8le 40, the support frame 20 with the t8le 40 and the layer of goods therein is raised very high, until the t8le stops, above the pallet to be loaded, itself located 3 side of the machine frame 10 or above the upper layer of goods already on the pallet. In this position of the frame 20 with the t8le 4o01 the t8le 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 upper layer of goods lying on a stack on the pallet. When the tCle 40 has taken this positbon, the retaining bar 45

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

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

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

  The sheet of goods on the sheet is placed on the pallet P. i When the transfer process is complete, the sheet 40 takes the position shown in Figure 5 and a new layer of goods can be

: loaded.

  ti * If it is for goods that have already been placed! on the pallet, parcel and if, now, bags should 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 t8le in the machine b9tl and a new pallet is brought into the unloading area. If, now, a layer of bags has been prepared on the t8le, the t8le 40 is brought above the pallet, in the same manner as described above, and after the retaining bar 45 is lowered, the t8le 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. In this way, it is possible to transport, in the loading area, pallets-I i L tes carrying merchantjes_ bchaque fni ffrn poer dur l

  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.

  511 In order 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 , according to another embodiment of the invention. This storage device 200 is arranged

  in the machine frame 10 which accommodates the goods supply slide

  ses 220, sliding horizontally, sliding which can be arranged as a - rotating roller conveyor * or as a continuous rotating conveyor belt. The direction of delivery 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 Y1, by means of a control mechanism not shown in the drawing and serving for the transfer of the layer of goods formed on the supply slide 220 on an Ifr 240 racr.3lagis f20 f transfer 240 device, connected to the supply slide 220. The direction of movement of the transfer bar 221 is transverse with respect to in the sense of arrival of

goods (Figure 6).

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

  of unloading, pivots 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.

  13cj The transfer device 240 is arranged as a conveyor

  i or with rotating rollers 243 or as a continuous rotating conveyor belt, so that the layer of goods consisting of the end of the supply slide 220 can be brought in the direction of the arrow Y3 to the

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

: 35, transfer location 240.

  'As regards the example of execution shown in Figure 7, two storage channels 230 and 330 are arranged one above the other, at an interval, the distance between the two storage channels 230 and

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

  a Each storage channel 230 and 330 is arranged in the machine frame 10 i 1 0 in the direction of the arrow Y4 or Y5. and is movable in height so that

  l 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 330 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 channel the form of a floor or a sheet (for packages) movable i I horizontally. The dimensions of storage lanes 230 and 330 are designed

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

  S! if the storage tracks 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 tracks to

  the tale for parcel 40 of the pallet loader 100, devices which move

  'cent in the direction of the arrows Y6 and Y7 i using control mechanisms

  X 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 I tale 40 of the charger 100. If, on the other hand, the storage channels 230 and 330 are themselves designed as t8les that can move horizontally, the 201 supporting frame 20 of the loader 100 has devices capable of gripping these t8les, which are then removed from the corresponding fixings provided in 1 i machine b9ti 10 and transferred using the carrying frame 20 in the area where the pallet to be loaded P is located The pivoting axis 245 of the transfer device 240 should preferably be placed on the plane lying between! 251 the two storage channels 230 and 330, so that the transfer device

  should not perform too large oscillations.

  t The number of storage lanes does not necessarily have to be limited to two. A higher number of storage lanes arranged

  f one above the other can also be provided. The trans-

  301 fert 240 is then designed so that the transfer of the layer of prepared goods onto the supply slide 220 on the different

  } storage routes are possible, without any disturbance.
