Definitions

  • the object of the present invention relates to a machine for distributing or selling bags of the type of those which use a tubular and continuous strip of plastic material, normally provided with a series of transverse weld lines and perforation lines. or weakening, the distance between them corresponds to the length of each bag after it has been separated from the continuous strip.
  • These machines are particularly usable in establishments and large centers or markets intended for the sale of products, preferably food, where the buyer introduces the articles which he has bought in one or more bags supplied by the machine.
  • US Patent 4,336,681 relates to a bag dispensing machine in which the bags are stored in the form of a continuous tubular strip which has, at regular intervals, perforations delimiting the bags and which is driven by electric motors actuating rollers tension and pressure of the bag strip. An electrical contact is provided to detect perforations between bags and to consequently control the stopping and operation of the motors. Finally, a system is provided downstream to separate the bags from the strip. It is however important to observe that the detection and the separation of the bags are done individually, the machine being intended to distribute only one bag at a time, while the present invention aims to provide a machine allowing, at will, the distribution of 'any number of bags.
  • an electronic circuit receiving the signal from a push button or a switch connected to the keyboard of a cash register for payments in order to select the number of bags to be dispensed triggers the operation of the electric motor actuating the traction roller of the tubular strip, the circuit comprising a member detecting the passage of the bags, and the pusher or the switch sending an electrical signal applied to a counting apparatus or to the recording machine for the purpose to count and record the number of bags distributed, and to cut through the means of detection the current of the electric motor actuating the traction roller of the strip of bags, thus stopping the drive cycle and the supply of bags.
  • the bag separation device comprises means making it possible to apply, to the final bag to be separated from the continuous strip itself, a series of tensile forces applied successively at points aligned transversely, these tensile forces breaking segments successive lines of dotted zones or weakening zones which connects the bag to the rest of the strip, until complete separation of this bag.
  • This or these bags exit outside through a front opening of the machine and, as they are obtained in a continuous strip wound or folded in a zig-zag inside the machine and separated by a weakened or stamped part, the buyer himself can take the units that came out of the machine.
  • the machine object of the present invention thanks to the reduced size of its elements and because it does not have a coin mechanism and a case for storing money or tokens, has a relatively and considerably light appearance; and if the place where it is placed does not have a conveyor belt, it can be placed on a table or hung on the wall, its constitution and shape giving it a pleasant appearance.
  • the continuous strip (3) of bags placed in the lower compartment (2) of the machine can be wound on a reel (17) supported on rollers (18) which can be free-axis or self-powered, or can be folded in a zigzag form a block (19) placed in a housing (20) (fig. 2).
  • each bag (3a) In this type of strip, the separation of each bag (3a) from that which immediately follows or precedes it (3b) is marked by a transverse line of dotted lines (21).
  • these bags which can be made of plastic, paper, etc. have a detection element such as a matrix (22) or a printed strip, through which the microswitch (5) can be actuated next to the strip (3) which passes over the platform (4) .
  • this stamping (22) consists of one of the voids which form the handles (FIG. 2).
  • the timer (25) is activated by means of the switch (24) which through the microswitch supplies current to the electric motor (6) which starts the roller (7) which, thanks to the pressure exerted by the roller (8), drives the strip (3) of bags coming from the storage compartment (2); the microswitch (5) detects the passage of each bag of the band (3) and sends a signal which is received by the switch (24) until the quantity of bands to be distributed previously selected by the pusher (16) is reached, and then this switch (24) disconnects the electric motor (6), and the roller (7) then stops driving the bags.
  • the switch (24) simultaneously supplies a signal applicable to a counter or to a conventional payment recording machine (26) which records and notes the number of bags distributed on the corresponding delivery note or invoice.
  • This counter or recording machine in turn sends back a control signal which is received by the switch (24) (FIG. 3).
  • the strip of bags passes through the separation mechanism which produces the stretching of the exit bag (3c), finally causing the line of dotted line (21) which separates it from the next bag (3b) and distributes it in a separate state.
  • the bag separation mechanism (3) comprises a rotary shaft (27) actuated by a transmission and a drive member (not shown); on this shaft are fixed, in an integral manner, a series of radial fingers (28), equidistant from each other and phase shifted relative to each other by a reduced angle of the order of 10 ° by example.
  • each finger (28) (FIGS. 6 and 7) there is an extension (29) of flexible and elastic material, such as rubber or plastic, elongated along the longitudinal axis of the continuous strip ( 3).
  • the posterior end (30) of these extensions is significantly thinned. It should be emphasized that the curvature of the active surface (31) of this extension (29) has a radius R greater than the radius r that describes the surface (31) when it rotates.
  • the width of the bags may vary in the different bands placed in the store or storage compartment (2) of the machine, and for this reason the rollers (7) and (8), the opening (14) and the entry (12), as well as the separation mechanisms (11) will have the width which corresponds to the bags of greater width (FIG. 1).
  • the rear wall (35) of the machine is mounted on upper hinges (36) ( Figure 1) so that it can be opened and have access to the interior, or to place a new coil (17) or a block (19) of bags, either to replace the one that is already finished, or to intervene in the circuit or the mechanism of the machine.
