Definitions
- This invention relates to a processing device for caps and/or cap components of the type specified in the preamble of the first claim.
- this invention relates to a processing device, be it a bending or drilling or cutting machine, for caps and/or cap components mainly used in the food industry.
- caps for food products are characterised by two main components: the closure casing and the warranty seal of the product designed to certify the correct closure of the food container or to indicate that it has been opened.
- these machines may comprise straight or rotating mechanisms comprising spindles, arranged in a row or radially in relation to a central shaft, designed to remove caps or parts of caps from a continuous line and designed to process the caps themselves, or at least part of their components, along the processing line.
- the completed caps are conveyed back on a line away from the processing machinery.
- a gripping member takes a portion of the cap, usually the warranty seal, in order to cut the latter and prepare it for coupling with the containment casing.
- both the gripping member and the cutting member are equipped with rotating or static spindles that are synchronised and mutually centred to enable precision processing.
- the coupling step is carried out by means of two gripping members that respectively take the cap’s containment casing and the warranty seal and couple them under pressure by means of the above-mentioned devices.
- both members include spindles that must work in a synchronised manner and must be mutually centred to enable precision cap processing.
- either the gripping or processing member is static. Therefore, it is often necessary to use additional devices when the processing is complicated.
- a locking mechanism to the machine, such as a jaw, which increases the overall dimensions of the machine and which, in any case, must also be synchronised to ensure the correct execution of the whole process.
- mechanically independent gripping or processing members can be provided so that they can be independently moved and perform even the most complicated processing in a single pass.
- the technical task underlying this invention is to devise a cap component processing device that is capable of substantially overcoming at least some of the above-mentioned drawbacks.
- Another important purpose of the invention is to provide a processing device that makes it possible to maintain the centring between the different members even at high processing speeds.
- Fig. 1 shows a side section view of a processing device for caps and/or cap components according to the invention in a preferred configuration
- Fig. 2 illustrates a simplified diagram of a part of a cap processing plant including a processing device for caps and/or cap components according to the invention.
- the processing device for caps and/or cap components according to the invention is indicated as a whole by the reference number 1.
- the device 1 can be designed to perform a plurality of different processing operations depending on its components.
- the device 1 is preferably part of a cap processing plant 10.
- the plant 10 is preferably a plant designed to process various types of caps, for example screw caps for glass bottles or the like, for example, for the closure of paper and/or plastic packages, such as those produced by the company Tetra-Pak ® for containing fruit juice or milk or the like.
- the caps being processed generally consist of at least two portions: a closure casing, e.g. made of metal, and a warranty seal, e.g. made of polymer material.
- the closure casing is the portion of the cap designed to close the bottle. It can be made of various materials, for example polymer material or metal, more specifically aluminium, and may or may not include internal threads.
- the cap may also include a knurling or porous portion to increase the effectiveness of the grip and to enable the user to easily unscrew the cap.
- the warranty seal is, however, preferably an annular portion, e.g. made of polymer, that can be interlocked with the inside of the closure casing at the edge of the casing.
- the plant 10 shall preferably comprise at least one device 1 and at least part of an assembly line 6.
- the assembly line 6 is preferably a conveyor machine that is capable of moving caps or cap components along a predetermined trajectory.
- the assembly line 6 can be composed of a plurality of elements designed to define an assembly path 6a.

- the assembly line 6 also defines an assembly plane 6b.
- the assembly plane 6b includes the assembly path 6a and is, preferably, the plane along which the caps or cap components are placed.
- the assembly line 6 includes a conventional conveyor roller, for example, the assembly plane 6b is defined by the surface of the belts moved by the rollers, while the assembly path 6a is defined by the movement direction the belt imposes on the rollers.
- the assembly path 6a can, therefore, be straight, on the assembly plane 6b, or it can also follow a trajectory that lies on an arc of a circle, e.g. for assembly lines 6 working with devices 1 moving circularly on its own axis.
- the plant 10 preferably includes one or more devices 1 .
- the device 1 preferably defines a way station included within the plant 10 itself.
- the plant 10 may comprise a device 1 dedicated to cutting the warranty seal and a corresponding assembly line 6 and a device 1 dedicated to coupling the closure casing and the warranty seal.

- the positioning holes 40 are suitably arranged at the ends of the C-shape.
- the positioning holes are preferably designed to respectively house at least part of the first processing portion 2 and part of the second processing portion 3. In this way, the processing portions 2, 3 can remain locked facing each other.
- the positioning holes 40 are preferably centred along the processing directions 2a, 3a.
- the positioning holes 40 define the ends of a guide 41.
- the guide 41 is basically a preferred trajectory defined by the positioning holes 40 within which the caps being processed pass through by means of the processing portions 2, 3.
- the guide 41 therefore basically defines the alignment part of the processing portions 2, 3.
- the processing guide 41 is preferably and suitably also centred in relation to the processing directions 2a, 3a.
- the cap or cap component is then processed when arranged inside the guide 41.

- the first processing member 20 and the second processing member 30 are, instead, preferably in a spaced-apart position when the device 1 is in the first point A and when it is in the second point B.
- the operation of device 1 is basically such that, when the processing members 20, 30 are close together for processing, the positioning member 5 holds the cap firmly in place, while when the processing members 20, 30 are spaced apart, or moved apart, the positioning member 5 can be moved along the movement direction 5a so as to grip or not and, if required, move or position a cap.
- the invention also comprises, therefore, a new method for processing caps and/or cap components.

- the cap is processed by means of cooperation between the first processing member 20 and the second processing member 30 as they are brought close together.
- the cap is removed from the first processing member 20 by means of the positioning member 5.
- the steps for placing, processing, and removing the cap are advantageously carried out by moving the first processing portion 2, the second processing portion 3, and the positioning member 5 from the first point A to the second point B along the assembly path 6a.
- the cap in the first point A the cap is placed on the first processing member 20, in the second point B the cap is removed from the processing member 20, and in the movement between the first point A and the second point B, the first processing member 20 and the second processing member 30 cooperate in a close-together position by processing the cap.
- the processing device for caps and/or components of said caps 1 according to the invention entails significant advantages.
- the processing device 1 makes it possible to ensure the processing members 20, 30 are centred without using additional active mechanical devices or adopting solutions in which the two members are not operated independently.
- the C coupling means 4 also make it possible to couple different processing portions that can constitute both linear and circular assembly paths.
