Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a manufacturing device for a guide rail that forms the vertical frame and horizontal frame of a shutter.

[Prior art and problems to be solved by the invention] Generally, when the shutter curtain moves up and down in the fitting groove of the guide rail, the shutter curtain touches the mutually opposing edges on the opening side of the fitting groove. To avoid noise, a cushioning material such as plastic is attached to the edge of the shutter curtain to prevent it from directly hitting the opposite edge of the fitting groove. As a manufacturing device for such guide rails, Japanese Patent Application Laid-open No. 56
As seen in JP-A-93993 and JP-A-56-93531, a guide rail that has been formed into a predetermined shape using a forming machine is run through a degreasing machine to remove foreign matter and oil, and is then coated with an adhesive applicator. A method has been proposed that uses a series of molding machines and various equipment to apply adhesive, press the cushioning material to the opposite edge of the fitting groove using a cushioning material extrusion molding machine, and then pass through rolls, dies, and a cooling machine. has been done. However, with this method, in addition to the forming machine, many mechanical devices such as the degreasing machine, adhesive applicator, and cooling machine must be installed separately, which increases the number of steps and costs. There are drawbacks.

[Means for Solving the Problems] The present invention was devised in view of the above-mentioned circumstances with the aim of providing a manufacturing device for guide rails in shutters that can eliminate these drawbacks. A forming machine that forms the shape of a guide rail, a supply roll that is placed downstream of the forming machine and is wound with a buffer material having a fitting groove, and a supply roll that is placed downstream of the supply roll and has the buffer material on its circumferential surface. Consists of multiple guide rolls with receiving grooves for receiving materials.
The guide rolls are supported so as to rotate independently at predetermined positions within the rail material to be transferred, and guide the cushioning material received in the receiving grooves to be sequentially deflected toward the edge side of the rail material. The cushioning material is arranged so as to fit into the edge of the rail material.

With this configuration, the present invention provides a degreasing machine,
By making it possible to manufacture a guide rail with a noise prevention function without incorporating any machines such as an adhesive applicator or a cooling machine, the apparatus itself can be simplified and provided at low cost.

[Example] Next, an example of the present invention will be described based on the drawings. A is a roll-type forming machine for drawing the hoop material sent out from the uncoiler into a predetermined rail material D shape having a fitting groove. A supply roll B is provided for winding the cushioning material 1 in which the insertion groove is formed. A cushioning material 1 formed in advance by means such as injection molding is wound around the supply roll B, and a plurality of guide rolls C are arranged further downstream of the supply roll B. . The outer peripheral surface of this guide roll C is provided with a cushioning material 1 that is fed out from the supply roll B.
A receiving groove 2 for receiving the guide rolls C is formed, and these guide rolls C independently rotate a pair of guide rolls C having approximately the same outer diameter within the rail material D transferred from the forming machine A. The cushioning materials 1 are suspended via support shafts so that they can move, and are arranged at predetermined intervals so that the outer diameter gradually increases toward the downstream side. are successively deflected and guided toward the bent piece d side formed on the opening side edge of the rail material D, and at the final end guide roll _C1 , the cushioning material 1 is inserted. The bent piece d is configured to fit into the groove. Incidentally, reference numeral 3 denotes a guide for guiding the cushioning material 1 fed out from the supply roll B to the receiving groove of the guide roll C at the starting end.

In the embodiment of the present invention as described above, the cushioning material 1 is attached to the bent piece d of the rail material D fed out from the forming machine A.
In this case, the cushioning material 1 is deflected and guided toward the bending piece d side by the guide rolls C arranged so that the outer diameter dimension increases sequentially, and the cushioning material 1 is inserted into the guide roll C at the final end. The bent piece d fits into the groove by forcibly expanding it, and thereby the cushioning material 1 is automatically fitted into the bent piece d. Once installed, the cushioning material 1 is clamped and fixed to the bent piece d by its own spring back action, and can be cut without coming off even in the subsequent cutting process.

As a result, guide rails with cushioning material can be manufactured extremely easily in a series of processes without incorporating conventional degreasing machines or adhesive applicators into the guide rail manufacturing process, which greatly contributes to cost reduction. Not only is this possible, but since the cushioning material is attached and fixed completely in a dry manner, other devices such as a cooler are not required, and the guide rail can be manufactured with an extremely simple and simple configuration.

[Operations and Effects] In summary, since the present invention is constructed as described above, the rail material is formed into a guide rail shape by the forming machine, and then a cushioning material is attached to the edge thereof. However,
In this case, the cushioning material is automatically fitted into the end edge of the rail material by being sequentially deflected and guided toward the end edge side of the rail material by the plurality of guide rolls. Therefore, without incorporating a degreasing machine or an adhesive applicator into the guide rail manufacturing process as in the past, guide rails with cushioning material can be manufactured extremely easily in a series of processes, and can be provided at low cost. Furthermore, since the cushioning material is attached and fixed completely in a dry manner, other devices such as a cooler are not required, and the guide rail can be manufactured with an extremely simple and simple structure.
