Description

State of the art product stacking box:

The product stacking box essentially consists of an infeed conveyor ( 3 ) containing the product packages ( 2 ) from the discharge belt of the packaging installation in the inlet direction ( 1 ) takes over. At the end of the infeed conveyor, the products ( 2 ) are counted before they are thrown into a collection tray. When throwing in, the products describe ( 2 ) a trajectory. The trajectory is in the inlet direction ( 1 ) by a large baffle plate ( 5 ): the products ( 2 ) bounce off the baffle plate ( 5 ) and fall into a collection tray below ( 17 ) on a circulating fan belt ( 7 ). The fan belt ( 7 ) has its running direction transverse to the running direction of the inlet belt ( 3 ). The number of desired products ( 2 ) in a collective box ( 17 ) of the fan belt ( 7 ) is adjustable and forms the respective product stack ( 22 ). Is the product stack ( 22 ) complete, clocks the fan belt ( 7 ) around a collecting tray ( 17 ) and a new empty collection tray ( 17 ) positions itself under the throw-in tape ( 3 ) to the next products ( 2 ) to a product stack ( 22 ) to collect. The fan belt ( 7 ) with the product stacks ( 22 ) in the collection compartments ( 17 ) is timed to an operator who positions himself at the end of the plant and the finished product stacks ( 22 ) can be easily removed with a handle from the subjects to supply them to a final package, z. B. a cardboard. The cycle performance of standard product stacks is limited by the time that the fan belt ( 7 ) needed to create a finished product stack ( 22 ) under the throw-in tape ( 3 ) before adding new products to the next empty collection bin ( 17 ) can be thrown.

This is where the invention begins:
The HighSpeed product stacking box (German: high-speed product stacking box) sets in the limiting time by the Vortakten the fan belt. Since the time the fan belt ( 7 ), a finished product stack ( 22 ) can be increased only insignificantly, the invention shares the formation of the product stack ( 22 ) in 2 sub-steps.

In a stacking box ( 3 )) (Protection claim 1), the infeed conveyor ( 3 ) partially encloses, is above the fan belt ( 7 ) an extendable clipboard by a catch plate ( 6 ), which is limited to the front by the baffle plate ( 5 ), backwards through the catch plate ( 8th ) and laterally through the lateral housing parts ( 4 ); on the extended catch plate ( 6 ), the first products ( 2 ) of a stack as a pre-stack ( 12 ) collected.

There is the pre-stack ( 12 ) from at least 2 product packages ( 2 ). The pre-stack ( 12 ) always forms the first partial stack of the product stack ( 22 ). By forming a pre-stack ( 12 ) on the catch plate ( 6 ), the time required to load the fan belt ( 7 ) with the finished product stack ( 22 ) below the catch plate ( 6 ) to advance a position and a new empty collection tray ( 17 ) under the catch plate ( 6 ).

The stack formation in substeps:

Sub-step 1

• - fan belt ( 7 ) with empty collecting compartment ( 17 ) is below the inlet belt ( 3 ) in position
• - the feed unit ( 9 ) has the catch plate ( 6 ) horizontally within the stacking box in the direction of the large baffle plate ( 5 )
• - in this way, the horizontally extended catch plate ( 6 ) a clipboard to store products ( 2 )
• - the first incoming packs ( 2 ) form the pre-stack ( 12 ), which is limited downwards by the catch plate ( 6 ), backwards through the catch plate ( 8th ) and forward through the baffle plate ( 5 )
• - the pre-stack ( 12 ) is formed
• - the feed unit ( 9 ) pulls the catch plate ( 6 ) back to the starting position under the infeed conveyor ( 3 )
• - the pre-stack ( 12 ) falls into the empty collecting compartment ( 17 ) of the fan belt ( 7 ) underneath

Sub-step 2

• - the other incoming packs ( 2 ) fall directly on top of the pre-stack ( 12 ) on and together with this the finished product stack ( 22 ) - the product stack ( 22 ) in the collection tray ( 17 ) is finished

Sub-step 1

• - the feed unit ( 9 ) the catch plate ( 6 ) horizontally
• - the fan belt ( 7 ) clocks under the extended catch plate ( 6 ) around a collecting tray ( 17 ) in front
• - a new empty collection tray ( 17 ) is ready for filling

and all the steps are repeated.

The HighSpeed product stacking box is used in the industry for high speed packaging machines, especially for thin packages with variable dimensions, as well as limited space in the production area, in the final packaging of sensitive products (such as food), which require a final quality control of the products manually and should be done visually by an operator.

The products ( 2 ), z. B. thin packages, with up to 180 cycles per minute, in succession, from an upstream packaging machine in the inlet direction ( 1 ) on the infeed conveyor ( 3 ) of the HighSpeed product stacking box, where they are counted individually and in a defined number in a stacking box ( 3 ) are transported to the stacking box as a product stack ( 22 ) in a collective box ( 17 ) lying on a circulating fan belt ( 7 ) and to be fed to an operator who loads the stack ( 22 ) with a handle from the collecting compartment ( 17 ) takes, on the occasion, the products ( 2 ) undergoes a final quality control and the product stack ( 22 ), if the products remain without complaint, the final packaging supplies. In this way the products ( 2 ) counted by the invention quickly and in order, collected, stacked and checked by the operator and fed to the final packaging.

For transporting the product stacks ( 22 ) serves a circulating fan belt ( 7 ) with collecting compartments ( 17 ) thereon. The number of collection subjects ( 17 ) on the fan belt ( 7 ) is variable and depends inter alia on the package width of the products ( 2 ). The width of the fan belt ( 7 ) is variable and depends, among other things, on the packing length of the products ( 2 ). The height of the collection compartments ( 17 ) is variable and depends in particular on the height of the product stack ( 22 ). Within a collective subject ( 17 ), both the length and the width as well as the height of the packs ( 2 ) vary. The stacking box ( 3 ) has mechanical adjustment options to adapt to varying product and package dimensions. Thus, the HighSpeed product stacking box is able to flexibly process different product dimensions and to produce different stack heights.

The HighSpeed product stacking box is suitable for receiving and processing a maximum of 180 products per minute from the packaging machine. The thinner the packages, the more products can be stacked in a collection tray (same height), and the more efficient the equipment is for the operator or industrial user.

Example calculation: 180 packs per minute with a height of 10 mm enter the system and are fed to the operator as a stack of 120 mm height with 12 packs in the stack. The operator then has 4.08 seconds to carton the stack. This is a pleasant working time for an operator in manual final packaging. The HighSpeed product stacking box can be designed in a very short overall length.

The high performance of up to 180 packs per minute, with minimal space requirements and high flexibility in terms of product dimensions and stacking height, makes the HighSpeed product stacking box unique (unique feature) compared to all hitherto known product stacking boxes in industrial applications. Herein lies the technical novelty and invention.

The high performance is achieved by a stacking box (protection claim 1), which contains the HighSpeed product stacking box in addition to the standard product stacking box. The stacking box is shown ( 3 ).

The stacking box ( 3 ) is a stand-alone module (component), with which the existing standard product stacks can be retrofitted to upgrade them to HighSpeed product stacks.

The possibility of using the HighSpeed product stacking box is extensive in the packaging industry, especially in the case of fast production lines for thin packs as used in the food industry for sausages and cheese. Since the food industry in particular is committed to a final quality control of the products, it often works with operators in the final packaging. Here, the HighSpeed product stacking box as an automatic quick packing aid for the operator is of great advantage.
