Definitions
- the present patent application for industrial invention relates to a sewing machine for sewing a pocket on fabric and to a method for sewing a pocket on fabric.
- the present invention relates to a sewing machine for sewing pockets on apparel items, such as for example pants, shirts, T-shirts and the like.
- a sewing machine is a mechanical or electromechanical equipment used to join fabric, cloth, leather materials or the like by means of a seam, passing one or more threads of cotton or other materials through a needle that alternately oscillates from up down or vice versa.
- US5454336 discloses a sewing machine for sewing a pocket on fabric.
- Said sewing machine comprises a bearing frame and a work surface supported by the bearing frame.
- a loading and folding station and a sewing station are disposed on the work surface.
- a folding unit is disposed in the loading and folding station for loading and folding the pocket to be sewn on the fabric;
- a sewing unit is disposed in the sewing station for sewing the pocket on the fabric.
- a mobile sewing template is disposed in the sewing unit for sewing the pocket on the fabric. More precisely, the sewing template is suitable for being disposed over the fabric and over the pocket in order to hold and sew the pocket on the fabric.
- the sewing template is provided with a U- shaped slot suitable for acting as guide for sewing the pocket on the fabric.
- Said sewing template is mounted on the work surface in such a way to make not only vertical and transverse travels relative to the longitudinal axis of the work surface, but also lateral translations towards the loading and folding station.
- the sewing template can take the fabric and the folded pocket that is positioned over the fabric from the folding unit and transport the pocket and the fabric to the sewing unit in order to sew the pocket on the fabric.
- the sewing template must necessarily remain under the sewing unit until sewing is completed, before it can travel backwards towards the folding unit and take a new pocket to be sewn. It is manifest that such a solution inevitably implies a reduction of the number of pockets sewn in a given time interval.
- the number of pockets sewn in a given time interval is inversely proportional to the time required to complete sewing.
- DE19864688 and US4813362 disclose two sewing machines provided with a sewing template that is used for transporting a fabric and a pocket folded over the fabric between a loading and folding station and a sewing station.
- the sewing template remains in the sewing station for the time interval that is necessary for the sewing unit to sew the pocket to the fabric.
- the purpose of the present invention is to eliminate the drawbacks of the prior art by disclosing a sewing machine for sewing pockets on fabric, which is capable of reducing the manufacturing time and the sewing time of apparel items.
- the sewing machine of the invention used for sewing a pocket on fabric comprises:
- a folding unit disposed in the loading and folding station for loading and folding the pocket to be sewn on the fabric
- the peculiarity of the sewing machine according to the invention consists in the fact that the sewing template is fixed and disposed in the sewing unit.
- the sewing machine also comprises:
- An additional purpose of the present patent for industrial invention is a method for sewing a pocket on fabric; said method comprising the following steps:
- Fig. 1 is a perspective view of the sewing machine of the invention
- Fig. 2 is a perspective view of a variant of the sewing machine of Fig.
- Figs. 3, 4, 5, 6 and 7 are perspective views of the sewing machine of
- the sewing machine of the invention can be advantageously used for sewing any other type of apparel component or element, such as buttons, buttonholes or the like, on a generic apparel item.
- the sewing machine (1 ) of the invention comprises a bearing frame (T) and a work surface (10) supported by said bearing frame (T).
- the work surface (10) is rectangular and has one longitudinal axis (X) and four sides:
- a loading and folding station (SP) and a sewing station (SC) are disposed on the work surface (10).
- a folding unit (5) is disposed in the loading and folding station (SC) for loading and folding the pocket (60) to be sewn on the fabric (6), as shown in Fig. 3. More precisely, said folding unit (5) comprises a plate (4) that acts as template to support and fold the pocket (60) to be sewn on the fabric (6).
- a sewing unit (2) is disposed in the sewing station (SC) to sew the pocket (60) on the fabric (6).
- the sewing unit (2) comprises a sewing head (22) suitable for sewing the pocket (60) on the fabric (6).
- the sewing unit (2) comprises a sewing template (20) disposed over the work surface (10) and under the sewing head (22).
- Said sewing template (20) is fixed, that is to say mounted on the work surface (10) in such a way to exclusively make vertical and transverse travels relative to the longitudinal axis (X) of the work surface, without the possibility of making lateral translations towards the loading and folding station (SP).
- the sewing template (20) is suitable for being disposed over the fabric (6) and over the pocket (60) in order to hold the pocket (60) on the fabric (6) and sew the pocket (60) to the fabric (6).
- the sewing machine (1 ) comprises a loading gripper (3) that is different and separate from the sewing template (20) of the sewing unit (2).
- the loading gripper (3) is slidingly mounted on the work surface (10) in order to transport the fabric (6) and the pocket (60) disposed over the fabric (6) from the loading and folding station (SP) to the sewing station (SC) under the sewing template (20) of the sewing unit (2).
- the loading gripper (3) is shaped as a plate and comprises a housing (3a) shaped as a pocket, with slightly smaller dimensions than the pocket, in such a way that the loading gripper is disposed over the perimeter edge of the pocket (60) that is folded on the fabric (6).
- the pocket (60) does not change its position relative to the fabric (6).
- the loading gripper (3) is disposed on the work surface (10) in intermediate position between the loading and folding station (SP) and the sewing station (SC).
- Moving means (30) of the loading gripper (3) are connected to the loading gripper (3) and configured in such a way to move the loading gripper (3) in forward and backward travels along an axis that is parallel to the longitudinal axis (X) of the work surface (10). More precisely, said moving means (30) are configured in such a way to move the loading gripper (3) between a first end-stop position in the loading and folding station (SP) and a second end-stop position in the sewing station (SC).
- the loading gripper (3) never passes through the loading and folding station (SP), thus making it easier for the operator to load the fabric (6) on the work surface.
- the loading gripper (3) leaves the loading and folding station (SP) and moves towards the sewing station (SC)
- the operator can load a new piece of fabric (6) on the work surface, without having to wait until the sewing of the pocket (60) on the fabric (6) is completed by the sewing template (20).
- the moving means (30) of the loading gripper (3) comprise a support arm (31 ) that supports the loading gripper (3).
- Guide means (33) are connected to the support arm (31 ) to move the support arm (31 ) in parallel direction relative to the work surface (10).
- the support arm (31 ) is fixed to the guide means (33) in such a way to project above said work surface (10).
- lifting means are connected to the loading gripper (3) to move said loading gripper (3) in orthogonal direction relative to the work surface (10).
- the guide means (33) are disposed in the front side (100) of the work surface (10).
- the support arm (31 ) is suitably dimensioned in order not to interfere with the sewing template (20) during the movement of the loading gripper (3) from the loading and folding station (SP) to the sewing station (SC).
- the support arm (31 ) has suitable dimensions and volume for passing under the sewing template (20), as shown in Fig. 6.
- the guide means (33) can be disposed in the front side (101 ) of the work surface (10), as shown in Fig. 2.
- the guide means (33) are disposed above the work surface (10) at a sufficient height to avoid any possible interference of the support arm (31 ) with the folding unit (5) and with the sewing unit (2). Such a position of the guide means (33) leaves the front side (100) of the work surface (10) substantially free, thus making it easier for the operator to charge the pieces of fabric (6) on the work surface.
- said guide means (33) can be also positioned under the work surface (10), in such a way not to be visible. In such a case, a groove must be provided on the work surface (10) to connect the guide means (33) to the support arm (31 ) and to let the support arm (31 ) translate.
- the guide means (33) advantageously comprise:
- said guide means (33) can comprise an endless screw with axis of rotation parallel to the longitudinal axis (X), which is connected to the support arm (33) and moved by an electric motor.
- said method comprises the following steps: a) positioning the loading gripper (3) in an idle position between the first end-stop position in the loading and folding station (SP) and the second end-stop position in the sewing station (SC);
- the loading gripper (3) can immediately make a backward travel to the first end-stop position in the loading and folding station (SP), in such a way to take a new pocket to be sewn. Otherwise said, while the sewing unit (SC) sews the pocket (60) to the fabric (6), the loading gripper (3) can take a new pocket to be sewn in the loading and folding station (SP), thus consequently increasing the number of pockets that can be sewn in a given time interval.
