DE3044069A1 - Removal machine for containers moved on pallets - is for glass bottles in layers with turned-up layers of board between layers and tear open knives - Google Patents

Abstract

The machine removes containers such as new glass bottles, jars etc., transported in layers ore above the other on pallets with turned up layers of corrugated or full board being arranged between the individual layers with their side walls pointing downwards. The turned up intermediate layers are removed in each case before the removal of the separate layers of containers located below them and are placed into an adjoining collecting shaft fitted with guide rods to position the turned up intermediate layers. Tear-open knives are located in the collecting shaft in an area in which the corners of the turned up cover of intermediate layers are placed and the cutting edges of the tear-open knives at least partially project into that area covered by the turned up intermediate layers within the collecting shaft. This ensures that the tear-open knives cut the turned up cover intermediate layers side walls during their lowering.

Description

The invention relates to a machine for clearing up

Pallets transported in layers on top of each other, such as new glass bottles, Cans and the like. or solid cardboard are arranged, the side walls of which point downwards, which slip lid intermediate layers in each case before clearing the underlying individual container layers from the Clearing or lifting shaft removed and in an adjacent collecting shaft a., the one with guide rods for guiding the individual slip lid layers is provided.

New glass bottles are transferred from the glass factory to the processor on industrial pallets transported, whereby the basic pallet is predominantly a four-way pallet with rectangular Dimensions is used. As intermediate layers between the bottle layers, a corrugated or solid board with side walls is used. Are the side walls of the liner directed downwards, it is a snap-on lid intermediate layer; point if it is at the top, the intermediate layer is called a inverted floor intermediate layer.

The slip-bottom intermediate layers take the bottles practically as in The outer box, while the slip-lid intermediate layers are placed over the new glass bottles from above be put on. In any case, the top layer of the bottles is marked with a Protected slip lid and also serves as a transport lock and moisture protection a polyethylene film shrunk around the whole block.

The blocks thus transported to the processor are called New glass clearing machines in which the individual bottle layers are removed by means of a The clearing trolley is pushed onto its own conveyor belt for further processing (see Enzinger-Nachrichten, iundenzeit cIri ft der Enzinger-Union-Werke AG, 68 Nannheim 1, Volume 31, Jan. 1978, No. 1, Pages 51-55).

When the bottles are delivered in the blocks with interlayer bases then the side walls of the intermediate layers must be cut open so that the side walls can release the bottles. For this purpose there are at least at the corners of the centering frame, which are at the rear seen in the clearing direction, ripping knives, that tear open the corners (cf.

DE-AS 21 05 76?). Are on all four corners of the centering frame Ripping knife attached, then the additional advantage is achieved that when the intermediate layers inserted into a collecting shaft next to the lifting shaft by means of a suction device will1 fold the side walls outwards so that they are in the same plane as the The bottom of the intermediate layer run, which means that the stacking density is quite high.

If blocks with intermediate layers are used, then they are tear-openers in the area of the lift shaft neither required nor required, because no after The partition walls above are present, but the bottles are on the outside of the snap-on lid and practical after lifting the top snap-on lid stand free on the side.

Each slip lid brought over the collecting shaft then falls downwards, with the free edge of the side walls pointing downwards Intermediate layer on the floor of the intermediate layer underneath for support comes.

This makes the packing density very small, i.e. only a few can do it Interlayers are stacked in a predetermined space, as practically the space around between the bottom surfaces of two stacked slip lid intermediate layers remains free because of the side walls delimiting the space. To increase the packing density enlarge, i.e. to accommodate more intermediate layers in a certain space can, the side edges at the corners are torn open manually by an operator.

Then the side walls can be folded out until they are with the The bottom surface of the associated snap-on lid or the intermediate layer form a plane, whereby the bottom surfaces of the stacked slip lid intermediate layers - in in the same way as with the inverted floor intermediate layers torn open in the lifting shaft - come to rest on each other.

The object of the invention is, in a device of the type mentioned at the beginning A simple, inexpensive and effective way of manually tearing open the Avoid side wall corners of the slip lid intermediate layers.

This object is achieved according to the invention in that in the collecting shaft Ripping knives are arranged in the area in which the corners of the slip lid intermediate layers are located in the collecting tray when taken, and that the cutting edges of the ripping knife at least partially protrude into the area of the cover plate intermediate layers is covered in the collecting shaft, so that the ripping knife the corners of the side walls Tear open the cover interlayers when they are lowered.

Another advantageous embodiment of the invention is as follows: da.ß in the presence of a perpendicular to the direction of movement of the Abräumwa.gens perpendicular movable frame for holding suction cups of a suction device for suction of the intermediate layers on the frame, a plate is attached with recesses is provided by the tearing process, so when lowering the plate together with the sttlpdeckel-interlayer, the ripping knives at least partially reach through.

The ripping knife and the plate work together in which the ripping knife engage in the slots of the plate at least partially, so that the shear effect on the corners of the side walls is improved.

Another advantageous embodiment of the invention can be as follows: that the ripping knife at the upper ends of the guide rods for the slip lid intermediate layers are attached.

In a further embodiment of the invention there is the possibility of that the scissors are attached to the frame of the Abräumma.schine.

The plate has openings through which the suspended Absa.ur suction cups; vorri.ciltung h.inczurcllsrreifen.

In the relaxed state, i.e. when the side walls tear open is not taking place at the moment, the suction cups protrude beyond the plate by a certain amount, so that a slip lid Interlayer can be grasped with certainty can.

It is known to then use ripping knives in the area of the pallet lifting shaft to be provided if the interleaved bottom layers are to be torn open.

One application of this measure for slip lid intermediate layers is not possible because the top slip lid in each case is only loosely and with considerable Tolerance (up to 4 cm) rests on the necks of the covered bottles.

There is therefore a risk that bottles located at the corners be destroyed by the knife or bottles fall over. If that happens, then this, especially the broken glass, then leads to a shutdown of the entire process System or to significant disruptions. The tearing open of the side walls without significant Effort is only possible if there are no more bottles under the slip lid are located.

According to the invention, the ripping knife to avoid the mentioned disadvantages arranged in the area of the collecting shaft, still for the sake of simplification and cheaper drives of the scissors' own drives are dispensed with according to the invention.

Based on the drawing, in the two embodiments of the invention are shown, the invention and further advantageous embodiments are intended and improvements of the invention are explained and described in more detail.

It shows: FIG. 1 a schematic sectional view of a new glass bottle clearing machine, according to section line 1-1 of FIG. 2, FIG. 2 shows a plan view of the clearing machine according to FIG of Fig. 1, according to arrow II of Fig. l, certain to clarify the arrangement Components such as suction device and the like.

are let out, Fifr. D another embodiment of the invention in a sectional view taken along the line III-III of FIG. 1, with certain parts such as machine frames and the like to clarify the arrangement. are only shown schematically or are completely omitted.

Fig. 1 shows a clearing machine 10, which has a uhschacht 12 and has a collecting shaft 14. The so-called bottle table, which in general to the right of 3cm drawn lift shaft 12 is in the lig. 1 not shown. The basic structure of such a machine is given in the above-mentioned literature reference Enzinger-Machrichten, page 54.

The machine will now be explained in detail, as far as the structure of the machine is important for understanding the invention.

The machine has a machine frame made up of three or more Pairs of columns 16, 18 and 20 is formed, which in their upper area by transverse or longitudinal beams 22 can be added to the entire machine frame. In the upper area, i.e., attached to the side rails 22 are rails 24 and 26 (Fig. 2), a. on which the wheels 28, 50, 32 and 34 of a clearing vehicle designated as 36 in its entirety roll along. The clearing trolley 36 is formed from an approximately rectangular one Frame) 8, which frame has two longitudinal members 40 and 42 and two cross members 44 and 46 a.n their ends. Approximately in the middle between the pairs of wheels 28/52 or) o / n4 another cross member 48 is drawn in. On top of the cross member 44 and 48, which are designed as U-profiles with open U's facing one another are two parallel to each other and parallel to the side members 58 and 40 arranged webs 50 and 52 attached, which are used to hold a suction device 54 (Fig. 1) are used. Furthermore, the two webs are used to hold the stroke-piston-cylinder assemblies 56, 58, the rods 60 and 62 in Fig. 1 with extended piston rods are, at the free lower ends of a holding frame 64 for suction cups 66 attached is. The suction cups 66 are resiliently connected to the holding frame 64, so that thereby certain tolerances when resting together on a slip lid intermediate layer can be compensated. There are also perpendicular to the holding frame 64 downwardly extending retaining webs 68, at their free ends parallel to the frame 64 a plate 70 attached is. Structure and function of the plate 70 will be described below.

Below the plate 70 are four tubular columns arranged in a rectangle 72, 74, 76 and 78 arranged, which are fastened below on a support plate 80, which is attached to the pillars 16 and 18 via support claws 82 and 84. The columns 74 and 78 and if necessary also 72, 76 are divided into two column parts 86 and 88, wherein a handle 90 is attached to the column part 88 in order to hold the column part 88 or remove the column parts 88 from its storage and those in the collecting duct 14 accumulated intermediate layers to be able to remove. For this purpose is the lower one End of each column part 88 resiliently attached to the support plate 80 (no further details shown), so that the column parts 88 press in the direction of arrow F downwards and leave it hanging. The upper column parts 86 are indicated schematically by means of Carrier elements 92 are firmly attached to the pair of columns 18.

At the upper ends of the columns 72 to 78 are ripping knives 94, 96, 98 and 100 attached, which have a triangular shape and with their tip 102 to 104 protrude upwards, the knife edge 106 obliquely outwards as a hypotenuse falls off. The ripping knives 94 to 100 are arranged so that their tips 102 and 104 always within the side walls 108 of those to be collected in the collecting shaft 14 Slip lid intermediate layers 112 are located at the corners of the same. The standard lid interlayers 112 are briefly referred to below as the slip lid.

The plate 70 is significantly larger than the bottom of a slip lid and has slots 114, 116, 118 and 120 at their corners, which slots approximate follow the diagonals of plate 70. The depth of the slots 114 to 120 corresponds the size of the ripping knife. The plate 70 also has openings 122 through which the suction cups 66 (see FIG. 1) can reach through.

Brackets 124 and 126 are attached to the further cross member 48, which carry an L-shaped clearing rail 128 at their free ends.

The lifting shaft ln is provided to the right of the collecting tray 10, in which block guide elements 150 and 152 are arranged, which are used to guide bottle layers 154 on a pallet 156. In operation, the pallet 136 is not by means of further illustrated lifting devices in the direction of arrow "1 moved upwards.

The individual bottle layers can be seen in FIG. 1, with only Bottles 144 are shown in the top three layers.

The area N-N is the area that is level with the bottle table so that the bottles in this level N-N can be cleared away. The block will As mentioned above, formed from several layers of bottles 154 lying one on top of the other, with the bottles standing on the outer surface 158 of an inverted cover, the side walls 142 of the snap-on lid protrude downwards, and so the snap-on lid 140, the bottles 144 partially cover at least from above.

The mode of operation of the arrangement according to FIGS. 1 and 2 is as follows: The stack or the bloc with the individual new glass bottles is placed on the pallet 156 introduced into the lifting shaft 12 by means of conveyor devices known per se. The Abräumwagen 36 is in such a position that the space between the cross members 44 and 48 is located above the lifting shaft 12 (carriage D6 is driven all the way to the right). Then the holding frame 64 is supported by the piston-cylinder assemblies 56 and 58 moved downwards until the plate 70 together with the suction cups 66 rests on the uppermost slip-on lid 112, the bottom surface of which is in the plane N-N lies. Then the holding frame 64 is moved upwards in the direction of arrow F1, until the free side wall edges come free from the bottles.

The upper ends of the bottles standing at the top are located while still in the area below the level N-N. Then the clearing trolley Move in the direction of arrow F2 to the left until the plate with the holding frame, So the space between the two cross members 44 and 48 above the Collecting shaft l) (as shown in Figs. 1 and 2).

Then the storage frame 64 is wLrd with the plate 70 and the adjacent one Move the hooded cover 112 downwards by pulling the piston rods 60, 62 out of the piston-cylinder assemblies 56, 58 are pushed out. The tips 102 and 104 reach the corners of the slip lid into engagement and tear when the plate 70 goes down under the latter Force acting on the side walls 110 in the corner areas, with the slots 114 to 120 of the plate 70 cooperate with the knives 94 to 100. The plate 70 is moved down until the tips 102, 104 of the ripping knife 94 bis 100 are overlapped by the plate 70. Then the suction cups () 6 again bewlurlXet and the sttllpdeekel liner 112 is released, being through the correspondingly spaced tubular columns 72 to 78 is held. The next, dispensed slip lid intermediate layer 112 then presses the previous one downwards, so that a na.ch down wa.chsender Sta.pel forms. That matters with that the hooded lids do not fall into the shaft at an angle. There is also the possibility place the pallet 146 on a roller conveyor and together by means of a lifting device to move upwards, as described for example in DE-OS 27 16 296.

Fig. 1 shows the machine in the position in which the plate 70 after Lifting off the top slip lid is lowered so far that the corners of the side walls are cut open. Thereafter, the plate 70 with the suction cups 66 is back on pulled up to some extent, to a halt well above the N-N level to get. In the meantime, the pallet 156 is up in the direction of the arrow F1 has been raised in such a way that the bottom 140 of the slip lid on which the top bottle layer now stands up, lies in the N-N level.

The clearing trolley is now moved in the direction of arrow F5 to the right, so that the clearing rail 128 after the bottles located above the level N-N right pushes, which pushes the bottles onto the bottle table. In order to the Bottles do not fall apart during the clearing process on the transverse web 46 of the Abriumwagens 58 a resilient flap 150, which with the Abraumsehiene 128 cooperates and presses the bottles against the Abrlumschiene 128.

In the arrangement according to FIGS. 1 and 2, the knives are 94 to 100 attached to the upper tips of the tubular columns 72 to 78. It is, of course also the possibility of the knives 94 to 100 at the ends of the machine frame attached knife carriers 152, 154, 156 and 158 (Fig.)). Otherwise the arrangement according to FIG. 5 is identical to the arrangement according to FIGS. 1 and 2. In any case, guide elements 160, 162, 164 and 166 must then be arranged, which serve to guide the intermediate layers and either directly below the knife or other suitable locations.

It should be added that the suction cups 66 with the suction device 54 by means of hose elements (not shown) via programmed remote controllable ones Switching and control means are connected in such a way that the suction device 54 in the Area of the suction cups generates a controllable negative pressure that is used to lift the Intermediate layers 112 or 140 are sufficient. Such an arrangement is again in the "Enzinger-Nachrichten" cited above.

In addition, instead of a closed plate 70, a corresponding one can also be used Find frame construction use.
