Figure 3 is a side view of a stick cartridge configured to hold multiple roller blind sticks manufactured by the machine.
Description of Embodiments
[0017] Referring to Figure 1 , a roller blind manufacturing machine 10 according to an embodiment of the present invention may generally comprise a fabric unwinding station 12, a fabric cutting station 14, a roller tube attachment station 16, a fabric winding station 18, a bottom rail alignment station 20, a bottom rail pressing station 22, a film wrapping station 24, a stick offloading station 26, and a stick transport system 28. The machine 10 may further comprise a fabric and rail transport system 30 as illustrated in Figure 2. The fabric and rail transport system 30 is not shown in Figure 1 to avoid obscuring the other components of the machine 10.
[0018] The machine 10 may further comprise one or more controllers connected to one or more sensors associated with one or more of the stations 12, 14, 16, 18, 20, 22, 24, 26, the stick transport system 28, and the fabric and rail transport system 30. The one or more controllers may be configured to automatically control one or more of the stations 12, 14, 16, 18, 20, 22, 24, 26, the stick transport system 28, and the fabric and rail transport system 30 in response to the one or more sensors.
[0019] The fabric unwinding station 12 may be configured to unwind fabric from a roll 30. The roll of fabric may be supplied mounted on a standard A-frame 34. The fabric may be wound on a centre axle which is motorised to allow automated unwinding. The fabric may then be fed across a tensioner bar 36 for tensioning the fabric during unwinding. Sensors may be used to detect current position of the tensioner bar 36, and more fabric may be automatically released when needed.
[0020] The fabric cutting station 14 may be configured to cut unwound fabric into a length of fabric having front and back ends. The fabric cutting station 14 may, for example, comprise two long bars that press down on either side of the cutting line to keep the fabric flat and taut. The fabric cutting station 14 may, for example, further comprise an ultrasonic cutter for cutting through the fabric.
[0021 ] The roller tube attachment station 16 may be configured to attach the front end of the length of fabric to a roller tube. This step is described in detail in WO 2017/139833. The roller tube attachment station 16 may, for example, comprise an ultrasonic welder. The roller tube may be fed to the roller tube attachment station 16 from a hopper 38 holding multiple roller tubes.
[0022] The fabric winding station 18 may be configured to wind the length of fabric onto the roller tube. The fabric winding station 18 may, for example, two rubber coated rollers. The roller tube may rest on top of the rollers that are motorised, and which then turn the roller tube. With the front end of the length of fabric previously welded to roller tube, this action will wind the length of fabric onto the roller tube. To prevent slippage and keep the length of fabric flat on the tube, three pressing mechanisms may be provided to press onto the roller tube while it is winding.
[0023] The bottom rail alignment station 20 may be configured to align the back end of the length of fabric to a lower half-shell of a bottom rail. This step is described in detail in WO 2017/139833. [0024] The bottom rail pressing station 22 may be configured to press an upper half-shell of the bottom rail onto the lower half-shell to form an assembled roller blind comprising the roller tube, length of fabric, and bottom rail. As described in WO 2017/139833, the assembled roller blind may comprise a standard-width roller blind stick as an intermediate product. The bottom rail pressing station 22 may, for example, comprise two sets of rollers that come down and press a pair of placed upper and lower half-shells of the bottom rail together via a rolling motion.
[0025] The upper and lower half-shells of the bottom rail are described in detail in WO 2017/139833. The upper and lower half-shells of the bottom rail may be respectively fed to the bottom rail alignment station 20 and the bottom rail pressing station 22 from separate cartridges 40A, 40B respectively holding multiple upper and lower half-shells. A lifting mechanism may then lift the upper and lower half-shells from their respective cartridges 40A, 40B until the top one reaches an extraction position.
[0026] Referring again to Figure 2, the fabric and rail transport system 30 may be configured to pull fabric and respectively position the lower and upper half-shells of the bottom rail at the bottom rail alignment station 20 and the bottom rail pressing station 22. The fabric and rail transport system 30 may traverse between the fabric cutting station 14, upper and lower half-shell cartridges 40A, 40B, and the fabric winding station 18. In addition to pulling fabric, it may also contain grabbers used to pick up upper and lower half-shells of the bottom rail and place them in the correct position.
[0027] The stick transport system 28 may be configured to move the roller blind stick from the fabric winding station 18 to the film wrapping station 24 and the stick offloading station 26. The stick transport system 28 may be further configured to place an indentation spacer strip between the bottom rail and remaining portions of the roller blind stick. The indentation spacer strip may be extracted from a cartridge 42 holding multiple indentation spacer strips. A lifting mechanism may lift the strips from their cartridge 42 until the top one reaches an extraction position. The stick transport system 28 may also handle spinning of the roller blind stick when wrapping film at the film wrapping station 24.
[0028] The machine 10 may be thought of as having two halves governed by two traversing systems. The first traversing system is the fabric and rail transport system 30 that traverses across different stations and initially pulls the fabric, as well as grabs and places the upper and lower half-shells of the bottom rail. The second traversing system is the stick transport system 28 which initially transports the roller blind stick after fabric has been wound onto the roller tube. The stick transport system 28 then holds onto the roller blind stick for the rest of the process until finally offloading it at the stick offloading station 26. The handover from the fabric and rail transport system 30 on each stick manufacturing cycle occurs once fabric winding completes and the stick transport system 28 takes over.
[0029] The film wrapping station 24 may be configured to wrap the roller blind stick in plastic film. The film wrapping station 24 may, for example, comprise four separate film wrap mechanisms working simultaneously on one roller blind stick. In addition to saving time, this arrangement allows wrapping load to be evenly spread out, which is advantageous during the initial stage when trying to adhere the first end of the plastic film. With multiple points of support during wrapping, the bottom rail will not come loose under gravity, thus helping the wrap initiation process.
[0030] Referring to Figure 3, the stick offloading station 26 may be configured to offload the wrapped roller blind stick to a stick cartridge 44 configured to hold multiple roller blind sticks. The stick offloading station 26 may, for example, comprise a pair of arms that move down to pick up opposite ends of a roller blind stick. After a roller blind stick has been produced, it may be placed in a holder cell of the stick cartridge 44. The stick cartridge 44 may comprise multiple holder cells that are interlocked together to form a layer of holder cells that comprise a modular racking system for the roller blind sticks made by the machine 10. Multiple layers may then be staggered and stacked on top of each other to form a compartment for multiple roller blind sticks. The multiple layers of holder cells may sit on a pallet for easy transportation after the stick cartridge 44 has been filled. The pallet may be supported by an elevator platform. After the completion of each layer, the platform may automatically lower by the height of one layer, and a new layer of holder cells may then be placed on top of the just-completed layer. [0031 ] The machine 10 may be automatically controlled to perform the following sequence of steps in a fully automated method of manufacturing roller blind sticks.
