Device for supplying packaging machines with packaging material

A device for supplying a packaging machine with packaging material in the form of wound webs in bobbins, said device comprising:

• at least one bobbin storage (23, 24) disposed above the packaging machine;
• two bobbin-processing assemblies (42, 43) disposed one above the other,
• each of said assemblies (42, 43) having two working cogs (36 to 39), a first of said working cogs being located in a receiving position for receiving a bobbin (13 or 14), and the second of said working cogs being in a working position relative to a web of material running off a bobbin;
• and
• a vertically extending bobbin supplier (50) disposed for conveying the bobbins (13, 14) from said bobbin storage (23, 24) to said first and second working cogs (36 to 39) of both said assemblies,
• said bobbin supplier (50) having a vertical transport path which extends from said bobbin storage (23, 24) to a position adjacent said receiving position of said working cogs (36 to 39).

A device for supplying a packaging machine with packaging material int he form of wound webs in bobbins, said device comprising:

• two bobbin storages (23, 24) disposed vertically above the packaging machine;
• a horizontal floor-mounted supplier (15) disposed above said bobbin storages (23, 24);
• and
• two vertical bobbin lifts (28, 29), each assigned to a different one of said bobbin storages (23, 24) for transporting the bobbins (13, 14) form said floor-mounted supplier (15) to said bobbin storages (23, 24),
• wherein each bobbin lift (28, 29) comprises a bobbin receptacle (32),
• wherein, in said bobbin storages (23, 24), the bobbins (13, 14) are located in a bearing plane, and
• wherein each bobbin receptacle (32) is lowerable to a region below the bearing plane for a transfer of the bobbins.

A device for supplying a packaging machine with packaging material in the form of wound webs in bobbins, said device comprising:

• two bobbin-processing assemblies (43, 43) associated with the packaging machine and disposed one above the other,
• each of said assemblies (43, 43) having two working cogs (36 to 39), a first of said working cogs being located in a receiving position for receiving a bobbin (13 or 14), and the second of said working cogs being in a working position relative to a web of material running off a bobbin;
• and
• two bobbin storages (23, 24) for receiving different types of bobbins (13, 14) and disposed next to one another above the packaging machine;
• a common vertically extending bobbin supplier (50), associated with both bobbin storages (23, 24), for feeding the bobbins (13, 14) to a packaging machine located below said bobbin storages (23, 24);
• and
• an intermediate bobbin supplier for extracting the bobbins (13, 14) from said bobbin storages (23, 24) and for feeding the bobbins to said common bobbin supplier (50);
• wherein said intermediate bobbin supplier has a transport arm (54) which is mounted for pivoting movement about a shaft (56), which is displaceable for axial movement in a direction parallel to the axis of said shaft, and which has a transport cog (51) for receiving the bobbins;
• a vertical bobbin lift (28, 29) assigned to each bobbin storage (23, 24);
• a horizontal floor-mounted supplier (15) located above the bobbin storages (23, 24),
• the bobbins (13, 14) being feedable from said floor-mounted supplier (15) to said bobbin storages (23, 24) by means of the bobbin lifts (28, 29),
• wherein each bobbin lift (28, 29) has a bobbin receptacle (32), and
• wherein, in said bobbin storages (23, 24), the bobbins (13, 14) are located in a bearing plane;
• and
• means for lowering said bobbin receptacle (32) to a region below said bearing plane for a transfer of the bobbins.
