Abstract
The invention pertains to a device and a method for producing hollow bodies that are open on one side of predominantly plane material blanks by erecting and gluing their sides along prepared bending edges, wherein said device features a shaft that is arranged directly downstream of the erecting elements and accommodates the hollow bodies in order to cure the glued joints, and wherein the products are spaced apart from one another during their transport within the shaft. The transport device provided for this purpose preferably acts directly upon the glued edges or areas located adjacent thereto such that the glued joint is continuously stabilized during the curing process.
Claims20
A device for erecting predominantly planar material blanks along prepared bending edges of side areas into hollow bodies that have outer dimensions and an open top, comprising:
- at least one erecting element for erecting the side areas of the hollow bodies whereby free edges of adjacent side areas are brought into confronting relationship in a joining region;
- a shaft for accommodating several erected hollow bodies, wherein the shaft has an inner cross section corresponding to the outside dimensions of the hollow bodies;
- a first transport device that guides the material blanks along the erecting elements and introduces these material blanks into the shaft;
- and
- at least one second transport device including at least one transport element that takes hold of the hollow body in a joining region and transports the hollow bodies located in the shaft in a longitudinal direction (S) through the shaft.
A device for erecting predominantly planar material blanks along prepared bending edges of side areas into hollow bodies that have outer dimensions and an open top, comprising:
- a shaft for accommodating several erected hollow bodies, wherein the shaft has
- an inner cross section corresponding to the outside dimensions of the hollow bodies,
- an infeed at an upper end and a discharge at a lower end, wherein planar blanks are delivered to the infeed with the side areas laterally outside the shaft and the blanks are formed into hollow bodies within the shaft, and
- the formed hollow bodies are discharged at the lower end of the shaft;
- first transport means that urge the planar blanks into the upper end of the shaft;
- second transport means extending from the infeed to the discharge of the shaft, for lifting the side areas of the hollow bodies whereby free edges of adjacent side areas are brought into confronting relationship in a corner region to form the hollow bodies, and transporting the hollow bodies in the shaft along a longitudinal direction through the shaft to the discharge end of the shaft.
A method for forming hollow bodies from predominantly planar material blanks that have a base and side areas with free edges that were glued and which free edges are to be joined in corner regions as the side areas are erected from the base along bend lines, comprising:
- guiding the planar material blanks past erecting elements that lift the side areas to form hollow bodies in which the glued edges are joined to form closed corner regions;
- successively introducing the thusly erected hollow bodies into a shaft, in which the corner regions are held closed while their glued joints cure;
- and
- transporting a plurality of hollow bodies in the shaft while maintaining a predetermined spacing between the transported hollow bodies.
