Definitions

  • the invention relates to a vitreous body layer according to the preamble of claim 1.
  • the invention also relates to a vitreous body bundle and a packing method for producing a vitreous body layer.
  • glass-to-glass contact occurs on the external surfaces during the manufacturing process. It begins with arranging the glass tubes into layers of glass tubes and then into a bundle of glass tubes, which is held in a rectangular shape by shrink caps at the ends. The arrangement is carried out in the tightest packaging possible. When the pipe surfaces are forced into contact, a linear contact (contact line) results. Surface injuries or scratches can occur at the contact points along the contact line.
  • the pallet is lifted and lowered at least six to seven times. During this process, the pipe surfaces of the pipes move against each other. During transport to the customer, the movement of the transport means there is a high probability that the glass tube surfaces will rub against each other. The probability of surface damage to the glass tubes is very high.
  • the tube bundles are broken down again in the reverse order as during packaging, down to the individual glass tube, which is then fed into the processing machine, e.g. B. a vial machine etc., is fed either by hand or by means of a robot.
  • the processing machine e.g. B. a vial machine etc.
  • the glass tubes are often surface-coated.
  • the layer which is several nanometers thick, only offers protection as long as this layer is not scraped off by mutual contact becomes. Despite the coating, this often leads to surface damage and scratches. A surface coating cannot prevent scratches, but at best minimizes them.
  • the surface damage significantly reduces the strength of the entire glass tube, which also applies to the pharmaceutical containers made from it.
  • From the DE 27 29 966 is a container of tubes made of brittle material, such as glass or glass ceramic, whereby the tubes are packed tightly and in a rectangular arrangement and are exclusively covered at least at the ends and at the end faces by a shrink film in such a way that they are fixed in their position .
  • the pipes lie on top of each other and can become scratched.
  • the individual pipes can also be provided with an anti-slip coating, for example made of sprayed silicone, or with pushed-on rings made of polyethylene rubber or textile material.
  • the DE 20 121 582 U1 discloses protective caps attached to both ends of a glass tube to prevent the tubes from coming into contact and scratching the surface during packaging and transportation.
  • the protective caps serve both as spacers and to seal the open pipes.
  • the DE 42 25 876 C2 discloses a packing holder for rod-shaped objects, such as glass tubes and glass rods.
  • Two strips made of a film-like material enclose glass tubes arranged next to one another, thereby forming a multi-part belt which has receiving members for the engagement of one glass tube in each case.
  • the adjacent receiving members are connected to one another via a two-layer intermediate web.
  • the two strips are connected to one another using an adhesive and/or embossed seam.
  • a layer of glass tubes has such a belt at a distance from the ends of the glass tubes. Layers of glass tubes stacked on top of each other touch each other in the area of the belts.
  • the DD 224 555 A1 describes a method for packaging glass tubes using shrink film, in which a prefabricated, rectangular film sleeve made of plastic material is pushed onto the two ends of a glass tube package and these film sleeves are shrunk with appropriate shrink units. Before the prefabricated film covers are pushed on, the glass tube ends can be completely or partially surrounded with further stabilizing agents.
  • the DD 82 301 discloses packaging for shock-sensitive, tubular glass bodies. Equally spaced, trapezoidal flaps are punched into a pallet made of corrugated cardboard material, which are arranged offset from one another in the opposite unfolding direction and are raised to one side of the surface of the pallet. The raised flaps form a lateral boundary of the packaging items and prevent lateral contact.
  • the JP H09-295686 A discloses a spacer for a stack of glass tubes.
  • the spacer has semicircular recesses that are separated by ribs and in each of which a glass tube can be arranged.
  • the glass tubes can be arranged with an offset by the spacer, whereby more glass tubes can be arranged in the same total volume.
  • the spacer of the JP H09-295686 A takes up a lot of space between the tubes, which means that only a small number of glass tubes can be arranged compared to the total volume of the stacked composite. The same applies to some of the... WO 2015/037361 A1 known spacers. In addition, the production of this type of spacer is complex.
  • the WO 2015/037361 A1 but also reveals another possibility for a spacer. Accordingly, a band-shaped spacer made of paper or cardboard is arranged between the glass tubes. The spacer then takes on a wave shape. In this way, the distance between the glass tubes is reduced, so that more glass tubes can be arranged in the same volume.
  • the US3373540 discloses a vitreous body layer according to the preamble of claim 1.
  • the object of the invention is to provide a glass body layer and a glass body bundle in which surface injuries and scratches on glass bodies can be easily avoided from packaging to delivery to the customer. It is also the task to specify a method for producing such vitreous body layers.
  • the glass body layer comprises at least two glass bodies which extend in a z-direction and which are arranged next to one another in an x-direction, with at least two spaced spacer positions being provided in the z-direction along the glass body, in which spacers are arranged between the glass bodies.
  • the spacers are thread-like elements, with at least one thread-like element being provided in each spacer position.
  • At least one thread-like element is arranged between all glass bodies in each spacer position.
  • glass also includes thermally treated glass, in particular glass ceramic.
  • a “thread-like element” is preferably understood to mean a thin structure made of twisted fibers or strips of material.
  • the term “thread-like element” also includes cords, lines or ropes.
  • the thread-like element is a round cord, an oval cord, a braided cord or a cord, for example. B. from twisted foil strips.
  • the thread-like element can also be made from an extruded material.
  • the material of the spacers is preferably chosen such that there is no contamination of the glass surface through the formation of deposits or abrasion. At the same time, the material and shape of the spacers should also be chosen in such a way that production is as cost-effective as possible.
  • Between the glass bodies means that the spacers are arranged at least in the line of contact between the glass body surfaces of glass bodies arranged next to one another.
  • the thread-like elements keep the vitreous bodies of a vitreous body layer at a distance.
  • the thread tension should be chosen such that the vitreous body layer, which contains up to 30 vitreous bodies can include, to the extent that it is stabilized so that the vitreous body layer can be handled and can be stacked with further vitreous body layers to form a vitreous body bundle.
  • a vitreous body bundle can have up to 30 layers of vitreous body.
  • the thread-like elements do not have to have a holding or stabilizing function, since the necessary stability of the vitreous body bundle is preferably achieved by the coverings provided at the ends of the vitreous body bundle, for example by applied hoods, which can consist of shrink film, for example.
  • thread-like elements has the advantage that prefabricated spacers, which have to be arranged between the glass bodies and/or the glass body layers, can be dispensed with. There is no need to transport the prefabricated spacers back from the customer to the manufacturer or to dispose of the prefabricated spacers after unpacking the vitreous body bundles.
  • the thread-like elements also have to be disposed of or recycled, the volume of thread to be disposed of is very small.
  • the load built up over the respective vitreous body layer is transferred through further vitreous body layers within a vitreous body bundle exclusively at the support points of the thread-like elements.
  • a further advantage of the thread-like elements is that the production of vitreous layers can be automated and that unpacking the vitreous layers is simplified.
  • the thread-like element preferably wraps around at least one glass body, in particular all glass bodies of the glass body layer, at least partially.
  • “Wrap around” is preferably understood to mean gripping around the outer circumference of the glass body, with the thread-like element preferably also at least partially resting on the outer circumference of the glass body.
  • two thread sections of the thread-like element or elements are arranged in each spacer position between two adjacent glass bodies.
  • the thread sections as components of the thread-like element(s) form the spacers.
  • Two thread sections between two adjacent glass bodies have the advantage that under load the force is distributed over two contact points, which reduces the risk of the glass bodies breaking.
  • the glass bodies are preferably glass tubes or glass rods.
  • Glass tubes and/or glass rods can be arranged in a glass body layer as glass bodies.
  • glass rods are made of solid material.
  • the glass bodies are preferably cylindrical.
