Abstract

The filling machine (1) is fitted with a rotating drum (2) provided with housings for the reception of packages (8). The conveyor is composed of a chain (3) mounted on a drive pinion (4), activated by a drive variator (5), and on a freely rotating return pinion (6). On the outer side of the chain are push pieces (7) which collect the packages to be filled, supplied by a supply system (9), and introduce them into the machine and evacuate them once filled.

  PACKAGING CONVEYOR FOR FILLING MACHINES

OBJECT OF THE INVENTION

  s The present invention refers, as its title indicates, to a packaging conveyor for filling machines, these machines being equipped with a rotating drum provided with housings for receiving the packages to be filled, with a upper tank containing the product to be packaged and discharge valves which regulate the fall of the product in the packages to be filled. The purpose of the conveyor in question is to introduce the empty packages into the filling machine, to move them inside the latter during filling and to

  squeeze out once they are full.

BACKGROUND OF THE INVENTION

  Currently, in the canning industry, filling machines are usually used to package the various products to,. commerclallser. This type of filling machine usually has a rotating drum provided with housings to position the packages to be filled, an upper tank where the product to be packed is located and discharge valves which

  regulate the fall of this product in the packaging introduced into the machine.

  Currently, the introduction of empty packages into the filling machine and the exit of these once full takes place by means of devices which rotate in synchronism with the drum of the machine, and which

  usually known as an input star and an output star.

  These input and output devices are arranged on the periphery of the machine, and relatively close together, so that the all-in-one vacuum pack introduced into the machine travels inside it. about 320 before going out by the exit star, course during which the filling takes place

of the packaging.

  These packaging transport devices require a complex system of guides which guarantee that the packaging follows the process without precision and without touching. The output of full packages by means of an output star requires a control system synchronized with the input star and the rotating drum of the machine, which implies a considerable increase in the cost of the machine, as well as a difficult handling of it, given the

  frequent maintenance operations and subsequent production shutdown.

DESCRIPTION OF THE INVENTION

  To solve the problems cited, the packaging conveyor for filling machines which are the subject of this invention has been designed, which provides a series of construction features aimed at considerably simplifying the operations of introducing empty packaging into the filling machine, the movement of these inside the machine with the process distances, then the output of

these packages once full.

  According to the invention, the conveyor in question consists mainly of a chain with closed links mounted on a drive pinion activated directly by a variator motor and on a freely rotating return pinion. On the outside, this chain has pushers whose function is to recucillate the packaging to be filled supplied by a feeding system, to move it in

  the filling area of the machine and take them out when filled.

  The chain is mounted tangentially with respect to the rotating drum of the filling machine, and one of its ramifications, on its intermediate part, draws a curved path coinciding with the periphery of the rotating drum of the filling machine. The curved trajectory of the chain which coincides with the

  trajectory of the rotating drum of the machine has an amplitude of about 40.

  This conveyor therefore makes it possible to considerably reduce the distance traveled by the packaging inside the machine, the length of this distance being

  in any case sufficient to fill the packaging.

  The pushers responsible for moving the packaging are distributed uniformly along the length of the chain, to ensure the distance between packaging

  while moving them.

  Compared to those existing in the news, this carrier brings a series of advantages, such as a very simple design and easy handling by the employees in cases where it is necessary to eliminate or remove a packaging, since there There is no need to remove guides or other support elements from the packaging, thus avoiding loss of time and production.

DESCRIPTION OF THE FIGURES

  To complete this description and in order to facilitate the understanding of

  0 characteristics of the invention, this description is accompanied by a set of drawings of an illustrative and nonlimiting nature, on which the following has been represented: FIG. 1 shows a schematic plan view of the conveyor object

  of the invention, applied to a rotary filling machine.

  PREFERENTIAL REALIZATION OF THE INVENTI ON

  On the embodiment of the attached figure we can observe the conveyor object of the invention applied to a filling machine (l) provided with a rotating drum (2). This conveyor consists of a chain (3) with closed links, mounted on a drive pinion (4) activated directly by a

  drive motor (5) and on a freely rotating idler gear (6).

  The chain (3) has on the outside a series of pushers (7) responsible for collecting the packages (8) to be filled, for introducing them into the filling machine (l), for moving them over the filling area and for get out of

the machine (l) once filled.

  The arrangement of the pushers at intervals (7) on the chain (3) ensures a constant flow of packages (8) inside the machine, without these smelling.

interfere with their trajectory.

  As has already been said, these pushers (7) re-cross the packages (8) supplied by a supply system (9). In the embodiment shown in the figures, this system (9) is composed of an endless screw with variable pitch, which ensures sufficient distance between the packages (8), so that the pushers (7)

collect one by one.

  The chain (3) is mounted tangentially with respect to the filling machine (1) and one of its ramifications, on the intermediate zone, draws a curved path (10) which coincides with that of the rotating drum (2), on a

  section whose amplitude is about 40.

  After having sufficiently described the nature of the invention, as well as a preferred embodiment, it should be known, with timely effects, that the materials, the shape, the size and the arrangement of the elements described may be modified, to the extent o this does not imply an alteration of the essential characteristics of

  lo the invention, claimed below.
