Definitions

  • the invention relates to a method for producing cup-shaped, with a Insert-provided containers, such as coffee powder capsules, the cup-shaped Containers are first punched out of a container material web and then in a forming process.
  • the invention also relates to a device for carrying out such a device Process.
  • containers are often provided with inserts that can perform a wide variety of functions.
  • inserts that can perform a wide variety of functions.
  • containers in which moisture-sensitive powder is contained, provided with an insert that absorbs moisture and keeps the powder dry.
  • Other containers in which contain liquids can be provided with self-sealing inserts be so that despite damage to the container, the contents leak is prevented.
  • Other applications are to provide deposits which release a substance into the main room after activation, e.g. for capsules or cups for drinking water, in which after a piercing or similar a disinfectant liquid is dispensed in a controlled dosage.
  • Self-sealing inserts are also used for coffee powder capsules. There the inserts are usually provided on the bottom of the coffee powder capsules. to The capsules are prepared in a coffee machine with a needle pierced and water is introduced into the capsules through the coffee powder. After the coffee has been prepared and the needle is removed, the coffee powder capsules remain sealed due to the self-sealing insert. This prevents the remains of the coffee powder capsules from being removed hot preparation water leak and scald the user.
  • the containers are made from a container material web, for example one Aluminum band, shaped. They are punched out of a sheet and then by forming, such as deep drawing or blow molding. The Insoles themselves are punched out of a band-shaped insert material web, before they are placed in the containers. Punching out and inserting the Inlays, especially with self-sealing inlays, are often technical Difficulties connected: Self-sealing inlays show tensile stress a high elasticity so that when drilling through the container wall together with the Seal the hole immediately due to its inherent elasticity. In addition, the Surfaces of such self-sealing inlays have a certain adhesiveness, so that the hole edges when drilling through the self-sealing inserts stick together and strengthen the seal.
  • the high elasticity of the Inlay material has the consequence that a feed movement of the Deposit material tape can only be done at low speed or that only low tensile forces can act on the insert material. With high strain there is a risk that the insert band will deform and that at high clock rates the Punching process is carried out while the insert material web is still deformed.
  • the manufacturing process can only be designed economically if the Containers with high clock rates are provided with deposits and manufactured. Furthermore should generate as many deposits as possible per unit area of the insert material web so that after punching out only a small remainder of the insert material web remains as waste.
  • the invention is therefore based on the object of a method and a device for making inlaid containers that create high cycle rates combine with a good use of space of the insert material web. Concrete it is a process for the production of with an insert Provided containers, the cup-shaped container first of all The container material web is punched out and then shaped in a forming process become.
  • this object is achieved for the device mentioned at the outset solved that an insert material web, one the insert material web in one Work area overlapping container material web and one in the work area arranged punching device, through which the inserts on in a predetermined Order pattern arranged punching positions can be punched out and in predetermined Container positions can be applied to the container material web, is arranged.
  • a feed device through which the punching device and the Deposit material web at least in part of the displacement steps in essentially transverse to the web direction of the insert material web relative to one another movably drivable.
  • the direction of the preferably band-shaped Inlay material web corresponds to the direction of your longitudinal extension, at one Lining material webs of the unwinding direction wound on a roll.
  • the method mentioned can also be used if the material of the inlays is a material that is difficult to process, such as a fleece.
  • a fleece Such materials, as are used in particular in connection with coffee powder capsules, are difficult to punch out among other things, can only be handled with difficulty, have low dimensional stability, and have low tear resistance.
  • the method according to the invention it is possible for the method according to the invention to be used even with inlays made of polyurethane fleece, for example made of a thermoplastic polyurethane based on polyester or polyether.
  • the polyurethane fleece can be a polyurethane fleece with an air permeability of more than 300 l / m 2 / s and with a pore size in the range from 10 to 40 ⁇ m, preferably with a thickness in the range from 0.1 to 0.3 mm, preferably 0.16 mm.

  • such materials are used in connection with coffee powder capsules.
  • Another preferred embodiment of the method according to the invention is characterized in that the inserts are punched out of an insert material web and that the insert material web and the container material web are such are fed one on top of the other that the deposits immediately after they have been punched out from the inlay material web to the underlying container material web applied and connected to this.
  • they can two steps of punching the inserts and applying these inserts to the To a certain extent, combine the container material web in a combined step.
  • the punching can either be done with a classic punching tool, it is but it is also possible to replace punching with laser cutting.
  • the web of container material is usually made of sheet metal for example aluminum, already provided with a coating which a Application and simultaneous fastening of the inserts on the container material web allowed by simple local warming (typically the Coating around an acrylic-based heat seal lacquer.
  • Another preferred embodiment is characterized in that the Insert material web and the punching device between one after the other order samples to be punched out at least in part of the displacement steps essentially transverse to the unwinding direction of the insert material web relative are moved towards each other.
  • This solution is simple and enables a high clock rate when punching out and applying the inserts onto the container material web and also a good use of the area of the insert material web, so that the Amount of waste is reduced. Due to the relative movement transverse to the direction of the Inlay material web a feed is possible in which the inlay material web does not have to be moved. This will prevent the Inlay material web due to its own elasticity during the feed into it Direction deformed. As a result, the clock rate can be increased.
  • the insert material web hardly needs to be moved for the next step, which leads to the fact that the interlining material web also has only slight loads is exposed, which allows a high clock rate, even though the Inlay material web typically around materials that are difficult to process is.
  • the relative movement can be caused by a movement of the punching device or by a Movement of the insert material web are generated.

  • Deposits that are only arranged in the bottom area of the finished container such as For example, fleece inserts for coffee powder capsules only cover a small part from the area of the container material web from which the container subsequently follows be reshaped. Therefore, the deposits can have several in each order pattern Insert diameter be spaced apart.
