Definitions

  • the present invention relates to a quadrangular assembly machine for the manufacture of hollow cardboard manufactured products, especially boxes.
  • the main purpose of the present invention is to eliminate the aforementioned disadvantages. This result has been achieved, in accordance with the invention, by adopting the idea of making a machine having the characteristics described in the characterizing part of claim 1. Other means of realization are the subject of the dependent claims.
  • the advantages which derive from the present invention consist essentially in the fact that it is possible to simplify the control system of the organs intended for the treatment of the boxes in formation, and to adapt it according to the program to the production requirements as and when required. are presented in relation to the format of the boxes that one wishes to obtain; that it is possible to obtain greater production, more flexible and of better quality compared to traditional machines, with any suitable type of carton and format of the box to be produced; that a machine according to the invention is easy and reliable to manufacture even after a long period of operation.
  • FIG. 1 schematically represents the plan view of a quadrangular sewing machine for the formation of cardboard boxes according to the invention
  • - Fig. 2 schematically represents the front view of the machine of FIG. 1
  • - Fig. 3 schematically represents the side view of the machine of FIG. 1.
  • the belt of said carriage (6) is associated with a corresponding producing cylinder (20) whose rod is connected to the same to achieve the correct tension in relation to the length of the effective stroke of the carriage ( 6).
  • the effective stroke of said carriage (6) is adjusted either with the manual use of a traditional handle (19) or by means of an automatic system constituted by a ball screw, which is controlled by a correspondent electric motor with encoder and slaved to the central unit with microprocessors, and passing in a corresponding nut solidair to the mobile part of the trolley (6).
  • said means for driving the operating heads (10) comprise a producing cylinder (11) for each head (10), which is controlled by said central unit to allow training, on command, with a variable length stroke according to program and in relation to the size of the sewing box, from and to the corners of the latter.
  • the means for driving said form-carrying rod comprise a fixed body (9) inside which is housed a belt (90) actuated by a corresponding motor (8) and connected to the form-carrying rod flange-shaped element (92): the form-carrying rod being provided with linear elements (93) for sliding guide on ball trolleys (92), and said electric motor (8) being of the brushless type and slaved to said central unit with microprocessors, to obtain, on command, according to program, the drive of the form (7) from and towards the working surface of the four operating heads (10) which provide for the sewing of the box with the heat-sealing tape (12), and with a variable length and speed stroke in relation to the size of the sewing box. Since the stroke of the form rod varies according to the program, boxes can be sewn of any height.
  • said form rod is made of light extruded alloy.
  • four electric motors (16,17) are used, slaved to said central unit.
  • two (16) are connected, for example with worms and corresponding nuts, to the base of each operating head (10), so as to cause them, to control programmed in relation to the format of the sheet (1), the drive in the longitudinal direction of the machine.
  • the other two motors (17) are connected, for example in the same way, to the base of each operating head (10), so as to cause it, with programmed control in relation to the format of the sheet (1), the drive in the transverse direction of the machine.
  • the position of the operating heads (10) is adjusted automatically, according to the program of said central unit, either in the direction of the width than in the length of the boxes to be formed.
  • An electro-brake (21) is also provided to obtain the immediate stopping of the form-holder rod, and thus to prevent its spontaneous entrainment, in the event of an unforeseen electrical power cut or other functional anomalies. .
  • the operation of the described machine is as follows. Once the operator has placed the stack of chamfered cartons (1) on the panels (2), it comes brought to a useful level to allow the intervention of the suction cups (3) which suck a sheet and they insert into the drag rollers (100). At this stage, the sheet, dragged by means of the carriage (6), comes brought into position underlying the form (7), which is completely lowered, at the control of the motor (8), until placed with the own lower base in correspondence of the central portion of the leaf, that is to say of the internal base of the box to be formed.
  • the reversal of the above-mentioned motor (8) is controlled and the box is moved away from the form (7) by means of traditional flat springs (14) or by means of a pneumatic piston (120) whose rod is passing inside the above-mentioned rod and with the end intended to act on the bottom of the box to move it away from the form (7), so that the finished product spontaneously falls on a conveyor belt (15) under -which provides for its definitive distance from the machine.
