Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further advantages, features and details of the invention result from the following description, in which with reference to the drawings embodiments of the invention are described in detail. Thereby, the features described in the claims and in the description can be each single or in every combination be essential for the invention. It is schematically shown:

(2) FIG. 1 an embodiment of a sack stacking which is produced with the palletizing device according to the invention,

(3) FIG. 2 a top view of a supplying device according to the invention in a palletizing device according to the invention and

(4) FIG. 3 the embodiment of FIG. 2 subsequent to the sliding process.

(5) FIG. 4 shows a relationship between the main and secondary feed belts according to the present embodiments.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

(6) FIG. 1 schematically shows a lateral view how a sack stacking should be produced. This sack stacking comprises a plurality of different layers 230 which are here stacked to a sack stacking on a pallet 300. The pallet 300 is assembled on a lifting device 120 like shown with the double arrow and can be moved upwards and downwards. The drawing according to FIG. 1 shows an already progressed stacking process. The first layer is thereby processed in a way that the lifting device 120 is directly under the sliding table 114. At this time a layer 230 of filled sacks 200 is already assembled on the sliding table 114 like also shown in FIG. 1. If now the sliding table 114 opens the whole layer 230 falls a short distance to the lifting device 110 or to the there assembled pallet 300. Subsequently, the lifting device 120 is moved downwards with the palette 300 and with the layer 230 assembled on the pallet 300 so far that the sliding table 114 can reclose and take up the subsequent layer 230 through the slider 116. These steps are repeated as long as the desired staple height is reached and all layers 230 are assembled on the palette 300.

(7) FIGS. 2 and 3 show a palletizing process in a top view. Thereby, a process device 400 is intended which for example as a so called form-fill-and-seal-machine performs a filling and producing of the filled sacks 200. Subsequently, a schematic switch is shown which conveys the sacks 200 to a turning device 130 with different turning positions. Like it can be recognized the upper turning position is performed for a 90 rotation for the sacks 200 while on the lower side no or only a slight rotation of the sacks 200 is performed. Subsequently an embodiment of a supply device 10 according to the invention is assembled. This is performed with a main supply belt 20 and a secondary feed belt 30. The width B of the main supply belt 20 is thereby greater as the width B of the secondary feed belt 30. This results from the different palletizing tasks. The embodiment and the situation according to FIGS. 2 and 3 shows smaller sacks with which by high speed both conveyor belts 20 and 30 are used. Thereby, both rows 210 and 220 of the filled sacks are conveyed at the same time or mainly at the same time to the sliding area 112 of the sliding device. Subsequently, the slider 160 can perform the sliding movement and thereby perform the whole layer 230 from both rows 210 and 220 of the filled sacks 200 on the sliding table 114. If the layer 230 is assembled on the sliding table 114 an opening occurs like already described regarding to FIG. 1.

(8) Likewise a separate actuation possibility with an actuation device 22 for the main supply belt 20 and an actuation device 32 for the secondary feed belt 30 can be recognized. While with complex and possibly fast performing palletizing tasks the configuration is chosen like shown in FIGS. 2 and 3 with particularly great sacks and correspondingly long-lasting palletizing tasks a reduction of the conveyor belts can be performed. Particularly, only the main supply belt 20 is used and the secondary feed belt 30 is shut down. This shows one time more the high flexibility in the possible application possibility for a supply device 10 according to the invention.

(9) Reference is now made to FIG. 4, which is a view of the lower left hand block of FIG. 2 orientated vertically. Secondary supply belt 30, which slides in the direction of arrow S, is below primary belt 20 on one level.

(10) The previous description of the embodiment describes the present invention only within the scope of examples. Naturally, also single features of the embodiments as far as technically meaningful can be freely combined with one another without leaving the scope of the present invention.
