Abstract
A machine for packaging pieces such as tiles or bricks in general comprises an improved apparatus for tying up with wire already formed packs of said pieces. Said apparatus consists of means carrying out the feeding, the cutting and the positioning of a wire length - underneath the pack to be tied up und while the pack itself is being fed above - on two arms for winding said wire length around said pack, and it provides to wind said wire length around said pack through simultaneous rotation of said arms, immediately after the pack has been fed.
Description
- The present invention relates to the systems for packaging even packs of pieces being fed irregularly, and especially packs of tiles or of bricks in general. More specifically, the present invention relates to an apparatus for tying up already formed packs of tiles, especially packs of tiles formed with the rotary vice object of the European patent application No. 80107255.4 in the name of the same Applicant. This tying up apparatus has been conceived with the object of allowing a machine for packaging the said pieces to make the most of the advantages provided by the said rotary vice.
- The use of the vice according to the European patent application No. 30107255.4 allows in fact to operate at speeds for forming the packs of tiles which could never be obtained previously in this type of machines, wherein the need to improve also the devices - which, in the stages following that of forming the packs, provide for the tying up and the sorting out of said packs - appears besides evident. If, in fact, the tying up speed is not proportionate to the rythm at which the packs are formed, this will give rise to a choking in the system which undoes, in the tying up stage, the advantages obtained in the forming stage.
- The devices used so far for tying up packs of bricks or of tiles in particular actually provide, in general, for three working stages: in the first stage, the wire for tying up the pack is prepared and positioned; in the second stage, the formed pack to be tied up is moved over the already prepared wire; in the third stage, the tying up is performed. Moreover, a subsequent intermediate stage is often required to allow the various parts of the tying up device to recover their initial position for the following cycle. This implicates quite a slow running of the packaging machine section dealing with the tying up of the packs.
- In order to increase the speed of the tying up stage in the said packaging system, the present invention thus provides for an improved apparatus for the tying up of packs, wherein the feeding, the cutting and the appropriate positioning, under the pack, of the wire length for the tying up thereof, are carried out in a single working stage, while the pack itself is being fed above, whereupon, in a second stage, the pack is tied up with said wire length.
- The apparatus according to the present invention is characterized by means for the feeding, the cutting and the positioning of the wire length, vhich comprise at least a wire feeding roller unit arranged at one end of the said apparatus, a carriage with wire drawing gripper apt to move in the longitudinal direction from said end of the apparatus to the opposite end thereof, shears arranged between said feeding unit and said carriage with drawing gripper, and a pair of nippers for positioning the wire length, apt to oscillate between a position in which they grasp the wire being fed from the carriage with drawing gripper and a position in which they present the wire to the means for winding said wire length around the pack to be tied up.
- Preferably:
- - the means for winding said wire length around the pack to be tied up comprise a pair of oscillating arms with end grippers, the first arm being mounted slidable onto an oscillating support to perform oscillations of about 180° around a pivot centre external thereto, while the second arm is pivoted at one of its ends to perform oscillations of about 90° around the same;
- - the first winding arm is mounted slidable by means of rollers onto a support provided therefor, whereon it is subjected to the action of a spring, the said support carrying a retaining mechanism with contrast roller to balance the action of the spring alternatively with the tension of the wire grasped by the gripper of the arm itself;
- - a pair of alternatively working feeding units are provided;
- - the nippers for positioning the wire length are carried by end supports of a shaft being parallel to the path of the carriage with drawing gripper and being caused to oscillate by fluid pressure means;
- - the winding arms are caused to oscillate simultaneously and in opposite directions by a single geared motor, through a cam, a rocking lever and suitable control leverages.
- The invention will now be described in further detail, with reference to the accompanying drawings which represent, by mere way of example, a preferred embodiment thereof and in which:
- Fig. 1 is a plan view of the tying up apparatus according to the invention;
- Fig. 2 is a side view, with some parts removed, of the apparatus of figure 1, of which
- Fig. 3 shows a head view, also with some parts removed; all the figures of these drawings being schematic.
- The heretofore described apparatus for tying up packs of tiles or bricks is of the type wherein the tying up is carried out by means of a length of wire, usually iron wire, which is positioned from underneath between the two chains moving the pack forward, so as to be set with its terminals at 90° to each other in correspondence of one of the upper edges of the pack, such terminals being thus joined and twisted together by means of suitable nippers apt to fix the tying up.
- With reference to the drawings, in the apparatus illustrated one notes first of all the presence of means for transporting the
pack 1 to be tied up, said means consisting of a pair of longitudinalparallel transport chains 2 and of guidingsupports 3. These means are housed in the upper part of the frame T of the apparatus and can be clearly seen in figures 2 and 3, while they are not shown in figure` 1. - Right beneath the pack transport means, at one end of the frame T, the apparatus according to the invention comprises means for feeding the
iron wire 4 with which the tying up is carried out. Such means consist of a pair of side-by-side feeding units 5, each comprising alower advancement roller 6 and anupper pressure roller 7 controlled by afluid pressure cylinder 71. The twounits 5 work alternatively, each fed by a different skein ofwire 4, and they are brought in a working position through a transversal movement operated by afluid pressure cylinder 17, each unit after running out of the skein feeding the other unit. - The wire feeding means 5 feed a
wire drawing gripper 8 which is carried by acarriage 9, being movable from one end to the other of the frame T along a rail 9', under the control of a gearedmotor 10. With thewire drawing gripper 8 cooperate a pair ofnippers 11 for positioning the wire, said nippers being carried bysupports 12 which are keyed close to the ends of alongitudinal shaft 13 being parallel to therail 91. Theshaft 13, and with it the supports 12 and thenippers 11, can be caused to oscillate by afluid pressure cylinder 14 acting onto alever 15 fixed to theshaft 13. The wire drawing and positioning means are clearly illustrated in figures 1 and 3, but they are not shown in figure 2, which shows instead the wire feeding means, also shown in figure 1. To such means there are also associated shears 16 (figure 1) being interposed between thefeeding units 5 and thegripper 8. - The apparatus is completed by means for winding the wire around the pack to be tied up, said means comprising a pair of oscillating
arms nippers arms motor 22, provided with acam 23, and a connecting rod 24 which controls a rockinglever 25. This latter causes in turn the oscillation of the arm 18 - through a lever 25' withrack 26 meshing with agearwheel 27 positioned in correspondence of the rotation centre of said arm 18 (said rotation centre being external to thearm 18, at the end of asupport 28, onto the other end of which thearm 18 is slidably mounted) - and of thearm 19, directly through a connectingrod 25". The movement of thearm 18 in respect of itssupport 28 is guided by rollers 29 and it takes place thanks to the contrasting actions of a. returnspring 30 and of the tension of thewire 4 being retained by thenippers 20 and 21 - when said wire is present - or - when thewire 4 is absent - of a retaining mechanism comprising alever 31 fulcrumed on thesupport 28 and alever 32 associated to thelever 31 and carrying a roller 32' apt to engage a fixed stop 33 of the frame T of the apparatus. The means for winding the wire around the pack to be tied up are placed in the upper part of the frame T and they can be seen in all three figures of the drawings, but particularly in figure 2. - In operation, the
pack 1 to be tied up with theiron wire 4, is transported by thechains 2 in a tying up position (figure 2) and, at the same time, the length ofwire 4, required for the tying up, is prepared and positioned beneath thepack 1 itself. - The preparing of the
wire 4 starts by the feeding thereof on the part of the appropriate means 5: the wire, coming from a skein (not shown), is moved forward by means of thedrawing roller 6 and of thepressure roller 7, up to being gripped by thedrawing gripper 8 which is open in the position indicated by A in figure 1. Upon subsequent closing of thegripper 3, theroller 6 stops, theroller 7 is lifted by the cylinder 7' and thecarriage 9 moves towards the opposite end of the frame T of the apparatus, thereby transporting thewire 4, clamped by thegripper 8, through the entire length of said apparatus. As seen, there are twofeeding units 5, which are used alternatively under the control of the cylinder-piston 17, so as to prevent the apparatus from stopping each time the skein feeding thewire 4 in each unit has run out of wire. When thecarriage 9 has reached the position indicated with B in figure 1, thenippers 11 for positioning the wire are caused to oscillate about theshaft 13 by thecylinder 14, up to moving into a suitable position for grasping the wire 4 (an intermediate position of thenippers 11 is shown in dashed lines in figure 3). The closing of such nippers then takes place and, straight after, the opening of thegripper 8 and the operation of theshears 16 which cut thewire 4 immediately downstream of its feeding means 5. Beneath the station at which thepack 1 must arrive, the wire length for its tying up is thus ready to accomplish its task. Such length must at this point be handled by thearms nippers 11 are again oscillated, in a direction opposite to the previous one, up to moving under thenippers 20 and 21 (position indicated in full lines in figure 3) which are placed at the ends of saidarms nippers 11 and thegripper 8 in the previous stage. The wire can thus legrasped by thenippers nippers 11 takes place. At this point, thepack 1 has in the meantime reached its tying up station (figures 1 and 3). The gearedmotor 22 therefore starts to work and causes thearm 18 to oscillate by about 180° around the point 18', thanks to the movement which the rockinglever 25 imparts onto therack 26 and to the rotation which this latter imparts onto thegearwheel 27. Simultaneously, thearm 19 is caused to oscillate by about 90° by the connectingrod 25" of therocking lever 25. The twoarms wire length 4 is positioned with its terminals facing each other at 90° in correspondence of an upper edge of thepack 1. Now the tying up with conventional methods may take place. It should be noted that thearm 18 is inclined, under the action of thespring 30, to keep permanently stretched thewire 4 grasped by thenippers retaining mechanism arm 18 from moving under the action of thespring 30 during grasping of the wire length. - The skilled in the art will have already understood, from what has been said above, that the apparatus according to the present invention allows to considerably reduce the dead times which are normally present in the operations for tying up packs of tiles and the like when using the apparatuses of known technique. In fact, the two stages comprising the feeding of the pack and the wire positioning which - as mentioned hereabove - conventionally take place in succession, in the apparatus described take place simultaneously, and also simultaneous are the stages comprising the return of the winding
arms - It is understood that the above description and drawings only illustrate by way of example the characteristics of the invention, and that other embodiments thereof may be possible and will appear evident to the technicians skilled in the art.
- Also the specific details concerning the mechanical solutions to be adopted in the described apparatus which, to make the description simpler and clearer, it has been found preferable to illustrate in schematical terms, will appear quite evident to the skilled in the art.
