Definitions
- the present invention relates to a process for manufacturing scrubbing mop parts which have a plurality of non-woven felt strips which are secured via one of their ends to a small head from which the handle or shaft of the mop emerges.
- the invention also applies to the installation for implementing said process, which permits complete control and total automation thereof.
- Spanish Patent 452,831 is known and it envisages a process and an apparatus for assembling floor mops in which there are initial stages when a flexible and absorbent material, which forms the floor mop, is cut, said strips later to be grouped together and held in a grouping-together housing of the mop part of the floor mop.
- Spanish Patent 477,531 is also known, relating to a machine for the continuous production of floor mops, and it consists basically of a rotary head which has at least three radial arms on which the stages of assembling the floor mop are carried out simultaneously, with an intermediate stage during which the continuous strips of the floor mop are cut, these becoming independent on each element of the floor mop.
- the Spanish patent with publication number. 8505812 is known, which relates to a machine for producing floor mops of the type made up of bundles of multiple threads.
- This machine envisages a movable head traversed by the bundle of threads forming the floor mop and this head can adopt two extreme positions at an angle of separtion of 90° which permit, with these positions, rolling-up, on the head, of the mop in two perpendicular directions.
- WO 96/08193 discloses a method of producing a mop head that comprises forming a core of elongate absorbent strip elements by coiling up a single web of absorbent strip material having slits formed therein defining the individual strip elements, and around an end portion of the core moulding a body of plastics material to form a means by which the core can be mounted on a mop handle, characterised in that prior to formation of the core, an end zone of the strip material, around which the plastics material is moulded, is subjected to a calendering process, wherein the strip material is pulled or driven between a pair of spaced apart contra-rotating rollers, in order to reduce its thickness and increase the density the strip material in the end zone.
- WO 95/08193 teaches a method in which a single edge of a moving absorbent strip material is calendered. The calendering of a single edge as disclosed in WO 96/08193 yields only one mop head per single web length processed.
- the present invention provides a process for manufacturing scrubbing mop parts which, based on the use of a length of non-woven felt band or other suitable material comprises the following operational stages of:
- the present invention further provides an installation for implementing the process for manufacturing scrubbing mop parts, comprising, in operational order, an accumulator (3), for the continuous band (1), which carries out the functions of synchronizing and adapting speeds during changeover operations, a band centring device (5), characterized in that the installation comprises a calender (6) for pressing two marginal borders (9), a stamping machine (12) for producing cuts (14) in the continuous band (1), said cuts being made with the exception of the calendered, marginal zones, a splicer (15) for making integral cuts (16) in the continuous band (1) and a conveying line (22), which ends in a discharge tray and in which there are a plurality of devices (23) which deflect downwards towards a series of twin mechanisms, each one of which has an oblique, downward conveyor belt (34) assisted by a mechanism (25) for applying adhesive to the calendered marginal zones (9) of each segment (17), a rolling up mechanism (26) and a cutting mechanism (29) for cutting the body of revolution (27) via its transverse median plane (30
- the process which the invention proposes is based on a continuous band of non-woven felt, of indefinite length, whose width is double the length envisaged for the strips of the scrubbing mop part and this band may be supplied, for example, in the form of a roll.
- the scrubbing floorcloth will be used as the unrolled strip forming the scrubbing mop part, before shaping, and the mop part will be used as the scrubbing-floorcloth piece once it has been shaped, by rolling-up, for use.
- said band is subjected to a calendering of its marginal zones with the aim of considerably reducing the thickness of said marginal zones in a non-varying manner.
- the continuous band is then subjected to a stamping operation during which uniformly distributed transverse cuts are made in the band, spaced apart so as to correspond to the width envisaged for the strips which are to form the floorcloth, this stamping operation mostly affecting the width of the band, specifically with the exception of the calendered marginal zones thereof.
- the continuous length, and each one of these undergoes separate processing.
- each of said sections is firstly subjected to a stage during which adhesive is applied to its calendered marginal zones and next subjected to a stage of being rolled up on itself, with controlled pressure on said calendered marginal zones, and, finally, the roll thus obtained is cut transversely through its central zone to obtain two identical scrubbing mop parts which hitherto were opposite each other; a solid core of reduced volume is formed on each one of them, corresponding to the end of the strips where these are joined together via the calendered border to which adhesive has been applied, from which solid core the group of strips forming the actual mop part emerges, expanding radially, its fullness being a function of the length given to the segments during the stage when the continuous band is divided.
- the purpose of the abovementioned discharge tray is to collect the continuous-band segments which have been discarded as unusable via means for inspecting the band, on the basis, for example, of the abnormal increase in thickness produced at the join between two continuous-band rolls as well as, in addition, a possible excess of continuous-band segments which the equipment for applying adhesive, rolling up and cutting cannot absorb.
- This equipment for applying adhesive, rolling up and cutting deposits the scrubbing mop parts obtained on a conveyor, located at a lower level, which in turn discharges the scrubbing mop parts which are oriented in a single line onto another conveyor which connects it with a bagging and boxing line for dispatch, this finishing off the installation.
- a band-centring device (5) which guarantees correct positioning of said band (1) at the entry of the calendar (6), whose heating resistor (7) is assisted by a temperature controller (8), the pressure between the rolls of said calendar being set by means of pistonless pneumatic cylinders in order to guarantee complete correspondence between the compressed-air pressure applied and the specific pressure on the material.
- This calendar (6) generates a pressing action on the two marginal borders (9) of the continuous band (1), as may be seen in Figure 2, thereby considerably reducing the thickness of the borders in said zones.
- a thickness detector (10) formed by a measuring roller, an analogue position sensor and a programmable comparator whose function is to detect the passage of the joins between the end and the beginning of rolls of material (1) with the aim of removing them via the discharge tray (11) located at the end of the line.
- the continuous band (1) then passes on to a stamping machine (12) provided with a base roll, corresponding to reference (12) itself, and a stamping roll (13) provided with a plurality of radial cutters which are spaced apart by a distance which is in keeping with the width envisaged for the strips which are to form the scrubbing floorcloth, the length of these cutters being such that they produce cuts (14) in the continuous band (1) which do not affect the marginal zones (9) which are in turn affected by calendering.
- a splicer (15) makes integral cuts (16) in the continuous band (1), defining in it segments (17) which are dimensionally suitable for producing a pair of scrubbing mop parts, as will be seen below.
- Calender (6), stamping machine (12) and splicer (15) are actuated by respective drive units (18), (19) and (20), with suitable supply and control means (21).
- a conveying line (22) based on two superposed planes of rollers, with segments (23) which tilt with the aid of cylinders (24) so that, via these tilting segments, the conveying line (22) can establish continuity throughout its length, discharging onto the discharge tray (11) or, alternatively, can effect downward deflections towards a series of shaping/cutting mechanisms which, in the practical embodiment shown in Figure 1, are four in number, although this number may vary as a function of the operating speed of said mechanisms compared with the speed of those mechanisms forming the initial part of the machine, i.e. of the calender/stamping machine/splicer line.
- a conveyor belt (34) forms part of each of these mechanisms, and it has a mechanism for reducing the width of the band, the latter being faced, from the side, by two mechanisms (25) for applying adhesive which apply a suitable adhesive to the calendered, marginal zones (9) of each segment (17) of the band, there being, beyond these mechanisms (25) for applying adhesive, rolling-up mechanisms (26) which cause the segments (17) to roll up on themselves and, through pressure, the adhering of the end zones of the body of revolution (27) thus obtained, which is shown in Figure 2.
- This body of revolution (27) is then supplied to a cutting mechanism (28), which is suitably motor-driven just like the rolling-up mechanism (26), whose cutter (29) attacks the body of revolution (27) transversely via its central zone, making in it a cut (30) to separate its two halves, each of which forms a totally finished scrubbing mop part.
