The invention relates to a folded fabric crushing machine used in the production of folded woven curtains used by connecting on all kinds of fixed, movable or folding windows, doors and glass balconies.
In particular, the invention relates to the folded fabric crushing machine, which enables the curtain fabric produced by the multi-layered fabric weaving technique to be produced without using adhesive material.
Buildings are the longest-lasting and significant energy-consuming structures in the economy sector and cover a wide range of products and services; for this reason, they are considered as a priority work area in policies and programs aimed at increasing energy efficiency and climate change. It is stated that heat losses in buildings are from exterior walls (40%), windows (30%), doors (17%), roofs (7%) and floors (6%). At the same time, 50% of the undesired heat increase that occurs in the summer in houses is also comes through windows.
In the present technique, honeycomb curtain systems are widely used to create insulated surfaces like moving honeycombs used in front of windows. Honeycomb curtain systems are basically based on the principle of attaching two pleated fabrics to each other directly with the help of an adhesive or indirectly with a separate strip piece with adhesive feature. When two pleats of fabric are glued together, they complete the structure of the honeycomb.
In current practices, two fabrics are required to form the honeycomb structure. The fabrics are first given the hardness required for the pleat crushing process and then they are taken to the pleat crushing process. In both fabrics, after the desired pleat height is achieved, they are glued with the help of a machine. Until the honeycomb curtain takes its final form, the cost of weaving production of the two fabrics, the cost of dyeing (drying), the cost of crushing the pleat and the cost of the adhesive are incurred. In addition, the adhesive used in the process has its disadvantages. Due to the use of adhesive, both the production cost increases, and the adhesion property is lost over time due to the temperature formed on the curtain, and the honeycomb structure formed for air storage may deteriorate. This is an undesirable feature regarding the service life of honeycomb curtains.
The document numbered EP0222534, which was found in the research conducted in the literature, can be shown as an example of the prior art. The said document is about the honeycomb curtain production method with band-joined folded material. According to the method of forming the honeycomb structure of the said invention, a first continuous length of material is fed along its length and its opposite longitudinal edges are folded over one side of the material. This folded material is then aligned with a second material in the form of a strip which is fed into overlapping relationship with one side of the folded material. These aligned materials are then folded and wound in a continuous loop to form layers of strip material. These sheets are glued together by bonding the strip material to the facing surface of the next sheet of material. In the said invention, an adhesive is used as a binder for bonding strip materials to each other.
Therefore, the existence of the above problems and the inadequacy of the existing solutions made it necessary to make an improvement in the relevant technical field.

In
As seen in
There is a comber (15) at the front of the table (10) that acts as a guide for the carrier guide threads passing through the curtain fabric to be properly connected to the thread pulling cylinder (31) in the thread pulling system (30). The said comber (15) also acts as a front bumper in the press system (40) and acts as a bumper to keep the curtain fabric crushed on the table (10) while the carrier guide threads in the curtain fabric are pulled.
The crushing cylinder (20), which enables the curtain fabric produced by the multi-layered fabric weaving technique to be crushed into pleats by means of the lower crushing cylinder (294) and the upper crushing cylinder (295), basically comprises, as seen in
The right main cylinder chassis (21) and the left main cylinder chassis (22) move on the table rail (13) on the table (10) by means of a linear bearing (28).
The motion of the lower crushing cylinder (294) is provided by the crushing motor (292) on the right main cylinder chassis (21). At the same time, the motion of the lower crushing cylinder (294) and the upper crushing cylinder (295) on the horizontal axis on the table (10) is provided by the motion motor (291) on the left main cylinder chassis (22). The said motion motor (291) works simultaneously with the crushing motor (292) and ensures that the curtain fabric is crushed at optimum speed and quality. The motion gear (293), which is associated with the motion motor (291), moves on the table motion gear (14) with the drive it receives from the motion motor (291) and provides the horizontal movement of the lower crushing cylinder (294) and the upper crushing cylinder (295) on the table (10).
The lower crushing cylinder (294) rotates in the crushing direction with the drive it receives from the motion motor (291), and together with the pressure of the upper crushing cylinder (295), crushes the curtain fabric. The rotation speed of the lower crushing roller (294) and the horizontal movement speed on the table (10) are simultaneous.
The upper crushing cylinder (295), together with the pressure it exerts on the lower crushing cylinder (294), ensures that the curtain fabric is crushed with its free rotation movement as it passes between them and the lower crushing cylinder (294).
The thread pulling system (30) which ensures that the carrier guide threads inside the curtain fabric that are attached to the thread pulling cylinder (31) with equal tension or length, are pulled for the crushing process, when the thread is attached to the carrier guide threads inside the curtain fabric, as seen in
The press system (40) that compresses the curtain fabric in a pleated manner is seen in
The horizontal press frame (43) is supported on the table (10) by means of the horizontal press linear bearing (46) and it moves on the horizontal press linear rail (47) on the horizontal press linear bearing (46). The vertical press frame (410) is supported on the table (10) by means of the vertical press linear bearing (48), and it moves on the vertical press linear rail (49) on the vertical press linear bearing (48).
The reducer system (50), which enables the curtain fabric ready for crushing process to be wound in the form of a fabric batch and fed to the folded fabric crushing machine at a constant speed and tension without releasing back, basically has a reducer (51) driven by an electric motor. It ensures that the curtain fabric advances with the tension determined on the table metal sheet (11) and there is no back-release.
The principle of operation of the folded fabric crushing machine, which is the subject of the invention, is as follows:
The fabric, which is produced with the multi-layered fabric weaving technique, is wrapped on the reducer system (50) and connected to the folded fabric crushing machine by means of the reducer (51). The curtain fabric is passed between the lower crushing cylinder (294) and the upper crushing cylinder (295) and is pulled up to the comber (15) located on the table sheet (11) at the front of the folded fabric crushing machine. Then, the carrier guide threads inside the curtain fabric are passed through the comber (15) in a way that one thread will come to each eye and they are tied, that is, bonded, to the thread pulling cylinder (31) in such a way that all the threads are at the same tension. Afterwards, the thread pulling motor (33) is operated to ensure that a certain amount of the curtain fabric is crushed behind the comber at the front of the folded fabric crushing machine. The thread pulling motor (33) operates synchronously with the reducer (51). Then, the crushing cylinder system (20) is positioned at the closest distance to the fabric entry point of the folded fabric crushing machine.
The lower crushing cylinder (294) and the upper crushing cylinder (295) are lowered to press with their own weight with the help of the crushing vertical pusher (24). Then, the crushing motor (292) and the motion motor (291) are started synchronously. As the crushing cylinder system (20) moves towards the exit side of the folded fabric crushing machine, the curtain fabric passing between the lower crushing cylinder (294) and the upper crushing cylinder (295) begins to be crushed at the inlet side of the folded fabric crushing machine. This crushing continues until all the fabric starts to peel off from the carrier guide threads.
After all the fabric is crushed, the crushed fabric is transferred to the exit side of the folded fabric crushing machine with the help of the thread pulling cylinder (31). First, the crushed fabric is pressed with the help of the vertical press pusher (45). Then, in order to fix the shape given to the fabric and to compress and pack it perfectly, with the help of the horizontal press pusher (42) the crushed fabric is pressed against the comber (15) with the help of the horizontal press frame (43) and it is completely compressed. Then, the carrier guide threads are completely pulled through the fabric and cleaned. After all these processes, the curtain fabric is locked in a special metal box and dried in special ovens. After this hot drying process, the crushed folded fabric is packed in cardboard boxes and it becomes ready for sale.
