Description

TITLE
AUTOMATIC MACHINES FOR THE PRODUCTION OF FACIAL FILTERING MASKS
Description
The technical field
[001] The technical field of the present invention has as its object the realization of a new automatic machine for the mass production of a new facemask, which is able, in addition to inserting and welding the typical ear support cords on the facemask, also to insert, sew and weld an additional cord around the throat of suitable length and adequate to support the facemask around the neck when not used for protection on the face.
Background
[002] The motivation and the need for the realization of a new innovative automatic machine for the production of facemasks is the direct consequence of a previous invention of mine, with deposit No. 102020000019654, where I inserted on the standard facemasks currently produced, an additional cord around the throat comfortable to support the facemask around the neck, when not used on the face.
[003] In order to effectively describe the technical characteristics of the new machine for the series production of facemasks for which protection is required, it is also necessary to describe the new facemasks to be made.
[004] The facemasks with only the ear support cords are problematic because, when they are not needed on the face for protection, you never know where to place them, and in any case it is very easy to get them dirty.
[005] The throat lanyard supporting the neck facemask is very comfortable to use, and solves the problem, but at the moment it can only be inserted and welded manually.
This entails a very expensive expense and a drop in productivity which makes production laborious and expensive.
[006] The current state of the art does not provide for the insertion of an additional lanyard around the throat to support the facemask on the neck, since it is not known so far and consequently the current automatic machines do not provide it.
[007] For this reason it is essential to have to build a new automatic machine producing facemasks with cords to support the facemask on the ears, which can also insert the throat cord to support the facemask on the neck when not used on the face and make it automatic in their production in series.
Purpose
[008] For this reason and to add an additional support cord to the neck, and to maintain the same production cycle as the currently existing standard automatic machines, we propose a new innovative automatic machine capable of solving the problem.
[009] The present invention whose protection is required, in one of the preferential constructive forms, adds to the standard machines on the market that insert only the support cords to the ears, a further cutting and positioning station of the throat lanyard, a further sewing station or ultrasonic welding to weld it on the facemask, achieving the purpose of creating an automatic machine that allows the complete realization of the standard facemasks.
[010] Consequently, the new machine has the advantage of being able to produce both the standard facemasks with only the ear support cords, and the complete mask with the throat cord that supports the neck mask, achieving the aim of having an automatic machine capable of to realize a very convenient series production of the facemasks.
[011] The throat lanyard can be of the same type used for the two support lanyards behind the ears, or of another type, suitable for being easily assembled and welded during production. Example by way of an exhaustive but not limiting example.
[012] The claims describe preferred variants of the invention and form an integral part of the present description. This and other objects are achieved by means of the invention described in detail below.
List of Figures and detailed description
[0013] The operation and characteristics of the new automatic machine for the series production of the new facemasks including the ear support cords as well as the throat cord for supporting the neck mask will be evident from the detailed description proposed below.
[0014] By way of example but not exhaustive, Fig. 1 (1 ) shows one of the many typical protective facemasks against viruses and bacteria called surgical that are currently produced with existing standard machines, and in the example case Fig. 1. (1 ), highlights two cords inserted on the mask Fig. 1 (2,3) which hook from behind the ears to support and hold the face mask on the face.
[0015] The same example also applies to the facemasks called KN95 or FFp2 which also have only the two ear support cords.
[0016] Looking at the same mask in Fig. 2 (1 ), the support cords for the ears are highlighted in Fig. 2 (2,3) and their terminals are visible in the contact points on the mask in Fig. 2 (4,5,6 , 7), where they are usually sewn, or welded with ultrasonic welding machines. Example by way of an exhaustive but not limiting example.
[0017] Fig. 3 (1 ) shows the body of one of the many types of filter facemasks on which the ear support cords highlighted in Fig. 3 (2,3) are sewn or ultrasonically welded at the points of contact with the mask. Fig. 3 (4, 5, 6, 7). Example by way of an exhaustive but not limiting example.
[0018] Fig. 3 (8) shows an additional support cord to hold the mask at the neck when not used for face protection.
[0019 Fig. 3 (9,10) shows the ends of the lanyard (8) with the contact points to the mask body Fig. 3 (1 ), to be sewn with sewing machines or ultrasonically welded depending on the materials used.
[0020] Fig. 4 shows the completely finished mask, consisting of the mask body of Fig. 4 (1 ) with the ear support cords of the mask of Fig. 4 (2,3) and the neck support cord around the throat of Fig. 4 (8).
[0021] As described above, existing automatic machines only provide for the application of ear support cords on the mask body Fig. 1 (2,3).
[0022] To add an additional lanyard around the throat of Fig. 4 (8), an additional machine unit is required, comprising a cutting station for inserting and positioning the lanyard on the mask and an additional stitching station or ultrasonic welding station for welding it to the mask.
[0023] The process is described in detail using the drawings in Fig. 5 and Fig. 6. [0024] Fig. 5 shows a standard machine producing ultrasonically welded standard facemasks, which in one of its designs is usually structured as follows:
[0025] Fig. 5 (11 ) shows the warehouse block with two lines of electronic reel unwinders, as shown in Fig. 5 (11a) and Fig. 5 (11 b), of TNT (non-woven fabric) thermoplastic material in quantities suitable for the requirements and the number of layers of the mask to be produced.
[0026] Next, in Fig. 5 (12) it is shown in Fig. 5 (12a) the block of an automated unit for aligning and positioning the various layers of the facemask, for their subsequent stitching, in a longitudinal way highlighted in Fig. 1 (1a) and transversal way Fig. 1 (1 b).
[0027] The stitching and lateral welding of the various layers is performed in the next block of Fig. 5 (12b) with the first two ultrasonic welding units of Fig. 5 (12c) and Fig. 5 (12d). In succession a third automatic unit of Fig. 5 (12e) is used for the subsequent cutting of the mask to the size set by the program.
[0028] The subsequent block of Fig. 5 (13) further comprises in Fig. 5 (13a, 13b) two cutting units for inserting and positioning the two ear support cords of Fig. 2 (2,3) on the facemask of Fig. 1 (1 ) with additionally two further ultrasonic welders, to weld the ends of the two ear support cords on the contact points of the facemask, as shown in Fig. 2 (4, 5,6, 7), thereby welding and completing the mask.
[0029] There is also a further block, Fig. 5 (14), with a unit for cutting and inserting the facemasks for transport to the inserting machine. Example by way of illustration but not limitation.
[0030] In order to produce the facemask with the addition of the neck support cord of Fig. 4 (8) and to achieve the same production as the standard machines, it is necessary to produce a new machine which allows the insertion on the facemask, in addition to the ear support cords of Fig. 4 (2,3), of the neck support cord of Fig. 4 (8). [0031] Fig. 6 proposes a new innovative automatic machine for the production of facemasks, which uses part of the structure of the existing standard automatic machines already described previously in the blocks of Fig. 5 (11 ,12,13,14) to which a further block highlighted in Fig. 6 (15) is added, comprising a further cutting station, and of insertion and positioning of the lanyard supporting the facemask at the neck Fig. 6 (15a), and a further ultrasonic welding unit Fig. 6 (15b).
[0032] The lanyard cutting and insertion unit in Fig. 6 (15a) has the feature of being able to insert and position a lanyard on the facemask that is longer than the ear support lanyards and of a more suitable length, so that the facemask can be comfortably hung around the neck when not in use on the face.
[0033] The subsequent ultrasonic welding unit of Fig. 6 (15b) welds the neck support cord of Fig. 3 (8), which was previously positioned by the insertion and positioning cutting unit of Fig. 6 (15a), onto the facemask in the position of Fig. 3 (9,10).
[0034] It is clear that the example description of the type of facemask described for the addition of the round throat lanyard (8) on the mask (1 ) is also valid for all the other types of mask produced, for example the typical Kn95 or the typical FFp2, where obviously in order to be able to automatically insert the round throat lanyard in series on the masks, the standard machines must be inserted and adapted with the addition of a further cutting station and a further ultrasonic welding station.
[0035] The claims describe preferred variants of the invention and form an integral part of the present description.
ADVANTAGES
[0036] One of the obvious advantages of the new machine proposed and described, in Fig. 6, is the fact that it maintains both the functions of a standard machine for the automatic production of facemasks including only the ear support cords, but also has the advantage of being able to produce the new complete facemask with the neck support cord, creating an automatic, mass-produced process, without changing the productivity of the two versions of facemasks compared to the current standard production, making production profitable in both versions. [0037] The invention can be modified while maintaining the inventive concept underlying it, each detail being able to be replaced with another technically equivalent one.
