Benefits of technology

The technical effects of this patent text are to provide a method for reel changing in automatic machines that can automate and speed up the process without the need for an operator. Additionally, the method should always ensure correct reel changing based on the requirements of the machine with reduced response times.

Problems solved by technology

However, the replacement process has several drawbacks:high costs, since an operator must be present at each automatic machine for constant monitoring of the machine in view of the large number of types of reels to be replaced together with the high operating speed of the machine;large physical effort by the operator for carrying reels from the storage unit to the automatic machine at each replacing request;possible risk of a machine stoppage if an operator is responsible for several machines (which are also not close to each other) and the two machines have a simultaneously request for changing the reel.risk of error in the loading of the type of material in the reel.

Embodiment Construction

[0026]With reference to the accompanying drawings and with particular reference to FIG. 1, the reel changing method according to the invention is used for automatic machines, denoted in its entirety by the numeral 1, used for making filter bags containing infusion products (such as tea, coffee, camomile and the like).

[0027]The automatic machine 1 comprises at least, on a machine front (that is, on a front vertical wall of a machine frame supporting the operating stations), a rotating shaft 2 for receiving at least one reel 3 of wound material, preferably of the filter paper type for forming filter bags for infusion products.

[0028]The rotating shaft 2 has a first identification code C1 (for example a position marker preferably of the type formed by a Charuco code).

[0029]As illustrated, the method for changing the reel 3 comprises the following steps:[0030]preparing a mobile carriage 4 having a robotic arm 5 equipped with a gripper 6 at its free end configured at least for retaining a...

Abstract

A method for reel changing in automatic machines including: preparing a carriage having a robotic arm including a gripped with a gripper at its free end for retaining a reel; the carriage has a support for the reel and a container for collecting cores of empty reels; positioning the reel on the support defining a predetermined position and memorised by the arm; moving the carriage forward toward a rotating shaft in a position allowing movement of the arm towards the shaft; reading a code on the shaft by a reading device on the arm; sending a signal by the reading device corresponding to the reading of the code to a processing unit with memorisation of the position of the shaft; picking up of an empty core from the rotating shaft and releasing the core in the container; picking up the reel; inserting the reel in the rotating shaft.

Description

TECHNICAL FIELD[0001]This invention relates to a method for reel changing in automatic machines. In particular, the method is used for the changing of reels in automatic machines used for making filter bags containing infusion products (such as tea, coffee, camomile or the like).BACKGROUND ART[0002]It is known that the automatic machines for making filter bags are provided with a plurality of reels for feeding various types of material necessary for forming filter bags. Each reel is supported by a corresponding motor-driven shaft protruding from a wall of the machine frame.[0003]In particular, each automatic machine is basically provided with at least one reel of filter paper (in some cases also two reels, of which one is for direct feeding and the other as reserve in the case of emptying the first reel) and a reel with strips of labels on which is added, in the case of packages with this option, also a reel of strips of material for wrapping the filter bags formed.[0004]It should b...
