Description

The present invention relates to a method for manufacturing a roof molding and a cutting device for the roof molding that are suitable for roof moldings that have flanges that protrude from the widthwise side edges of the head to the back side.

The roof of an automobile is constructed by joining a center roof panel located in the center of the vehicle width direction to side roof panels located on either side of it by spot welding or other methods. At this time, a roof groove is formed along the joint to hide the joint between the two roof panels, and a roof molding is attached to the roof groove to improve the design.

A roof molding generally includes a head that covers the roof groove, legs provided on the reverse side of the widthwise center of the head, and a lip that protrudes outward in the widthwise direction from the lower end of the legs, and is manufactured by cutting an extruded continuous molding into pieces of specified dimensions using a cutting device. Note that the roof groove is shallow at both ends in the vehicle's fore-and-aft direction to avoid damage during press molding of the roof panel. Accordingly, the legs and lip are cut away at both longitudinal ends of the roof molding to correspond to the depth of the roof groove.

For example, Patent Document 1 below discloses a method for cutting a roof molding including such legs and lip portions, and a cutting device for the same. The cutting method described in Patent Document 1 includes a leg positioning step in which the legs of the roof molding are positioned between a first cutting blade and a second cutting blade whose cutting edges face each other, a cutting blade opposing advancement step in which the first and second cutting blades are advanced toward the leg from both sides of the leg so that the cutting blades bite into the leg so as to sandwich the leg, and a cutting blade same-direction sliding step in which the head is fixed in position and, with the first and second cutting blades biting into the leg, moved toward one of the cutting blades.

The cutting device described in Patent Document 1 is configured with a cutting blade side mold in which a first cutting blade and a second cutting blade are mounted on a base with their cutting edges facing each other and capable of moving forward and backward in a substantially horizontal direction, and molding receivers are provided above the first cutting blade and the second cutting blade, supporting the underside of the head on both sides of the legs and allowing the legs to dangle between the cutting edges, and an operating side mold that is movable together with the first and second cams in a direction perpendicular to the direction of movement of the first and second cutting blades and that includes a first cam with a first contact surface that contacts the first rear pressed surface of the first cutting blade and a second cam with a second contact surface that contacts the second rear pressed surface of the second cutting blade.

JP 2001-300887 A

In addition to the general shape with a head, a leg, and a lip, some roof moldings have flanges that protrude from the widthwise side edges of the head to the back side. In this case, the cutting method and cutting device of Patent Document 1 cannot be applied to roof moldings with such flanges. In Patent Document 1, the first and second cutting blades are advanced horizontally from the widthwise outer side of the leg to clamp the leg, but at this time, the flanges located on the widthwise outer side of the leg come into contact with the first and second cutting blades. Therefore, if the first and second cutting blades are forcibly advanced, the flanges will be damaged or cut unnecessarily. In addition, if the first and second cutting blades are positioned so that they do not come into contact with the flanges, the positioning of the first and second cutting blades is limited, making it impossible to cut the leg into the desired shape.

The present invention aims to solve the above problems by providing a roof molding manufacturing method that can cut the legs of a roof molding having a flange portion that protrudes from the widthwise side edge of the head portion to the back side without the leg cutting blade coming into contact with the flange portion, and a roof molding cutting device for this purpose.

To achieve this, the present invention employs the following means.

The roof molding includes a head portion covering the roof groove, a leg portion provided on the back surface of the widthwise center portion of the head portion, a flange portion protruding from a widthwise side edge of the head portion toward the back surface side, and a lip portion protruding outward in the width direction from a lower end portion of the leg portion, and is manufactured by cutting an extrusion-molded continuous molding into pieces of a predetermined size by a cutting device,
the cutting device includes a first cutting tool and a second cutting tool each having a leg cutting blade and a lip cutting blade,
The first cutting tool and the second cutting tool are each movable in a horizontal direction and a vertical direction,
The leg cutting blades are arranged horizontally facing each other and are formed to be able to exist within a space surrounded by the head portion, the leg portion, the flange portion, and the lip portion;
The lip portion cutting blade is disposed facing downward,
a continuous molded body supplying step of supplying the continuous molded body in a longitudinal direction to the cutting device such that the leg portion is disposed between the leg portion cutting blades and the flange portion is disposed outside the leg portion cutting blades;
a leg cutting step of horizontally advancing the first cutting tool and the second cutting tool relative to each other at a predetermined location of the continuous molded body to cut the leg with the leg cutting blade;
A method for manufacturing a roof molding, comprising: a lip portion cutting process in which, while maintaining the leg portion cutting process in the state, the first cutting tool and the second cutting tool are each moved downward to cut the lip portion with the lip portion cutting blade.
(2) The cutting device has a third cutting tool equipped with a head cutting blade above the first cutting tool and the second cutting tool,
The method for manufacturing a roof molding as described in (1) further includes a head cutting step of moving the third cutting tool downward after the continuous molding supply step and cutting at least the head and the flange portion with the head cutting blade.
(3) The method for manufacturing a roof molding according to (1) or (2), wherein the cutting device is disposed so as to be continuous with the extrusion molding line which extrudes the continuous molded body.
(4) A method for manufacturing a roof molding as described in (1) or (2), in which, after the lip portion cutting process, the leg portion cutting blades of the first cutting tool and the second cutting tool are separated from each other before returning to the continuous molding supply process.
(5) A roof molding cutting device that is attached to a roof groove provided in a roof of a vehicle, comprising:
The roof molding includes a head portion covering the roof groove, a leg portion provided on the back surface of the widthwise center portion of the head portion, a flange portion protruding from a widthwise side edge of the head portion toward the back surface side, and a lip portion protruding outward in the width direction from a lower end portion of the leg portion, and is manufactured by cutting an extrusion-molded continuous molding into pieces of a predetermined size by the cutting device,
the cutting device includes a first cutting tool and a second cutting tool each having a leg cutting blade and a lip cutting blade,
The first cutting tool and the second cutting tool are each movable in a horizontal direction and a vertical direction,
The leg cutting blades are arranged horizontally facing each other and are formed to be able to exist within a space surrounded by the head portion, the leg portion, the flange portion, and the lip portion,
The lip portion cutting blade is disposed facing downward,
A roof molding cutting device capable of receiving the continuous molded body in the longitudinal direction so that the legs are disposed between the leg cutting blades and the flange portions are disposed outside the leg cutting blades.
(6) In a state in which the continuous molded body is received such that the leg portion is disposed between the leg cutting blades and the flange portion is disposed outside the leg cutting blades,
The first cutting tool and the second cutting tool are advanced horizontally relative to each other at a predetermined location of the continuous molded body, and the leg portion is cut by the leg portion cutting blade;
The roof molding cutting device described in (5) above, wherein the first cutting tool and the second cutting tool are each moved downward while being advanced forward, thereby cutting the lip portion with the lip portion cutting blade.

The continuous molding is then fed in the longitudinal direction to the cutting device so that the leg is disposed between the leg cutting blades and the flange is disposed outside the leg cutting blade, and the first cutting tool and the second cutting tool are advanced relative to each other to cut the leg with the leg cutting blade. According to this, the leg is cut from a state in which the leg cutting blade exists inside the flange, so that the first cutting tool and the second cutting tool do not come into contact with the flange when they are advanced. In addition, in the lip cutting process, the lip cutting blade is simply moved downward while remaining in the leg cutting process, so that the lip cutting blade does not come into contact with the flange even in the lip cutting process. Therefore, the flange portion is not damaged or cut unnecessarily during the leg cutting process and lip cutting process, and the cutting position and cutting shape of the leg cutting blade are not restricted by the presence of the flange portion.

According to the means (2) and (7), the head and flange portions are cut by a third cutting tool equipped with a head cutting blade, so that the continuous molding can be cut into a roof molding of a predetermined length.

According to the method (3), the extrusion molding line and the continuous molding cutting line are on the same line, so there is no need to move the extrusion molded continuous molding to the cutting device, and productivity can be improved.

According to the method (4), even if the scrap material (unwanted parts cut from the legs and lip) cut by the leg cutting blade and the lip cutting blade gets caught between the opposing leg cutting blades, the leg cutting blades are moved away from each other before returning to the next cycle process, so that the scrap material can be dropped reliably.

The present invention will be specifically described below by giving representative examples.
(Roof molding)
A roof molding 10 to which the present invention is applicable is attached to the roof of a vehicle such as an automobile 1, as shown in Fig. 1. The roof panel of the automobile 1 is composed of a center roof panel 2 in the center in the vehicle width direction and side roof panels 3 arranged on both sides of the center roof panel 2 in the vehicle width direction, and the center roof panel 2 and the side roof panels 3 are joined by spot welding or the like. Therefore, linear joints extending in the front-rear direction of the vehicle are present on both side edges of the roof panel, which does not look good as it is. Therefore, a roof groove 4 is provided along the joint between the center roof panel 2 and the side roof panel 3, and the roof molding 10 is attached to the roof groove 4 to cover and hide the joints.

2 and 3 show the roof molding 10 of this embodiment. The roof molding 10 of this embodiment includes a head 11, a leg portion 12 provided on the back surface of the widthwise center of the head 11, a flange portion 13 protruding from the widthwise side edge of the head 11 toward the back surface, and a lip portion 14 protruding outward in the width direction from the lower end of the leg portion 12.

The roof molding 10 is made of a thermoplastic resin such as an olefin-based elastomer (TPO) or polyvinyl chloride resin (PVC resin), or a rubber such as ethylene-propylene-diene rubber (EPDM), and is a long member with a nearly uniform shape in the longitudinal direction, produced by cutting a continuous molding 100 (see Figures 8 and 12, etc.) formed by extrusion molding into predetermined dimensions. Its length matches the length of the roof groove 4. At both longitudinal ends of the roof molding 10, parts of the legs 12 and lip 14 are cut out according to the depth of the roof groove 4 (which is shallower than other parts). The roof molding 10 is attached and fixed to the roof groove 4 via an attachment member not shown.

The head 11 is almost flat (slightly curved) and has a width dimension that covers the upper opening of the roof groove 4. The leg 12 extends downward from the back surface of the head 11, and a reinforcing metal core 15 is embedded inside. The flange 13 also extends downward from the back surface of the head 11, but is shorter than the leg 12 (about 1/2 of the leg 12 in this embodiment). As shown in FIG. 4, the flange 13 abuts against the upper surfaces of the center roof panel 2 and the side roof panel 3, preventing moisture such as rainwater from entering the roof molding 10 and the groove 4. In this embodiment, the center roof panel 2 is designed to be lower than the side roof panel 3, and moisture is diverted rearward along the flange 13 on the inside of the vehicle width direction, preventing rainwater from dripping onto the side window on the outside of the vehicle width direction. The lip 14 is in elastic contact with the side wall of the roof groove 4 when the roof molding 10 is installed in the roof groove 4.

(Cutting device)
5 and 6 show a cutting device 20 for cutting the continuous molding 100 to a predetermined length to obtain the roof molding 10. The cutting device 20 has a first cutting tool 25L and a second cutting tool 25R each having a leg cutting blade 21 and a lip cutting blade 22, and a third cutting tool 26 having a head cutting blade 23. The first cutting tool 25L and the second cutting tool 25R are connected to a cylinder device not shown in the figure, and can move forward and backward in the horizontal direction and the vertical direction, respectively. The first cutting tool 25L and the second cutting tool 25R always rise and fall at the same height position, and are arranged side by side in the width direction of the continuous molding 100 (roof molding 10) with a supply line of the continuous molding 100 described later between them. The first cutting tool 25L and the second cutting tool 25R are metal block bodies, and the leg cutting blade 21 and the lip cutting blade 22 are formed by wire cutting and cutting so that the upper edges of the opposing surfaces of each other protrude inward in the width direction by a predetermined amount.

The leg cutting blades 21 are formed facing inward in the width direction so as to face each other horizontally. The projection dimension of the leg cutting blades 21 from the upper edges of the first cutting tool 25L and the second cutting tool 25R may be such that, when the leg cutting blades 21 are butted against each other, the lip portion 14 fits below between the first cutting tool 25L and the second cutting tool 25R. In other words, when the leg cutting blades 21 are butted against each other, a space is formed below in which the lip portion 14 fits.

The leg cutting blade 21 is for cutting off the unnecessary leg 12 from the continuous molding 100 in a predetermined shape. Therefore, it is formed in a special shape. In this embodiment, the leg cutting blade 21 is a flat blade 21a from the midstream to downstream of the first cutting tool 25L and the second cutting tool 25R, and is a bulging blade 21b that bulges upward in the upstream part. The bulging blade 21b is formed integrally with the first cutting tool 25L and the second cutting tool 25R by wire cutting and cutting a metal plate. The bulging blade 21b is formed to a size that can exist in the space surrounded by the head 11, the leg 12, the flange 13, and the lip 14 of the roof molding 10 when the continuous molding 100 is received in the cutting device 20. Reference numeral 24 denotes a slit that receives the head cutting blade 23.

The lip cutting blade 22 is for cutting off a predetermined dimension of the unnecessary lip portion 12 from the continuous molding 100. The lip cutting blade 22 is formed facing downward on both the upstream and downstream edges of the leg cutting blade 21.

The third cutting tool 26 is disposed above the first cutting tool 25L and the second cutting tool 25R, and the head cutting blade 23 is provided downward from the underside of the third cutting tool 26. The third cutting tool 26 is connected to a cylinder device not shown in the figure and can be raised and lowered in the vertical direction. The third cutting tool 26 is disposed in the center of the width of the cutting device 20, and the width center line of the head cutting blade 23 coincides with the width center line of the supplied continuous molding 100. In this embodiment, the head cutting blade 23 is composed of a single blade arranged in parallel in the width direction. In addition, based on the supply line direction (longitudinal direction) of the continuous molding 100, the head cutting blade 23 is located on the slit 24 formed in the bulging blade portion 21b.

Upstream of the first cutting tool 25L, the second cutting tool 25R, and the third cutting tool 26, an upstream base 30 is provided to which the continuous molded body 100 is supplied. This upstream base 30 is installed continuously on the same line as the extrusion molding line of the continuous molded body 100 supplied from an extrusion molding machine not shown. In other words, the cutting device 20 is installed so as to be continuous on the same line as the extrusion molding line of the continuous molded body 100. Therefore, there is no need to move or transport the continuous molded body 100 from the extrusion molding machine to the cutting device 20.

Downstream of the first cutting tool 25L, the second cutting tool 25R, and the third cutting tool 26, a downstream base 31 is provided on which the cut and manufactured roof molding 10 flows. A groove 32 that matches the shape of the underside of the lip portion 14 is formed in the center of the width direction of the upper surface of the upstream base 30 and the downstream base 31. The groove 32 of the upstream base 30 and the groove 32 of the downstream base 31 are also on the same line. The upstream base 30 and the downstream base 31 are stationary.

(Production method)
Next, a manufacturing method of the roof molding 10 will be described. In the initial state of the cutting device 20, the first cutting tool 25L, the second cutting tool 25R, and the third cutting tool 26 are all in their upper limit positions. Also, the first cutting tool 25L and the second cutting tool 25R are in their retracted positions, and the leg cutting blades 21 are spaced apart from each other.

<Continuous Molded Body Supplying Step>
In this initial state, as shown in Fig. 7, the continuous molded product 100 is continuously supplied in the longitudinal direction from an extrusion molding machine (not shown) along the groove 32 of the upstream base 30 so that the leg 12 is disposed between the leg cutting blades 21. At this time, the bulging blade portion 21b of the leg cutting blade 21 is present in a space surrounded by the head 11, leg 12, flange portion 13, and lip portion 14 of the continuous molded product 100. That is, the flange portion 13 is located outside the bulging blade portion 21b of the leg cutting blade 21 in the width direction. In addition, in the vertical direction, the flat blade portion 21a of the leg cutting blade 21 is located between the flange portion 13 and the lip portion 14. The front view of the continuous molded product 100 shown in Fig. 7 is in a state before cutting, and the longitudinal tip surface is a flat surface.

<Leg cutting process>
When the continuous molding 100 is supplied to the cutting device 20 and the dimension of the continuous molding 100 downstream of the head cutting blade 23 becomes a specified dimension as shown in FIG. 8, the first cutting tool 25L and the second cutting tool 25R advance horizontally, i.e., toward the inside in the width direction, as shown in FIG. 9. Then, the leg cutting blades 21 come into contact with each other, cutting the leg 12 in a shape that cuts off unnecessary parts. At this time, since the flange portion 13 is located on the outside in the width direction of the bulging blade portion 21b, the leg cutting blade 21 does not come into contact with the flange portion 13 when cutting the leg 12. The timing for advancing the first cutting tool 25L and the second cutting tool 25R may be a specified time after the continuous molding 100 is supplied, or may be a timing when the continuous molding 100 passes a specified amount through the cutting device 20 by installing a proximity sensor in the cutting device 20, for example.

<Head cutting process>
In addition, in the leg cutting process, the first cutting tool 25L and the second cutting tool 25R are advanced, and at the same time, the third cutting tool 26 is lowered as shown in FIG. 9. Then, the head cutting blade 26 enters the slit 24 of the leg cutting blade 21, and the head 11 and the flange 13 of the continuous molding 100 are cut by the head cutting blade 26. As a result, the downstream side of the head cutting blade 26 becomes a roof molding 10 of a predetermined dimension. The amount of lowering of the third cutting tool 23 is sufficient to be such that the head cutting blade 26 can cut the head 11 and the flange 13 of the continuous molding 100, and the core material 15, which is harder than other parts, is cut by butting both the leg cutting blades 21 against each other. Also, the third cutting tool 23 may be lowered until it reaches the core material 15, and the core material 15 may be cut by the head cutting blade 26.

The head cutting process may be performed simultaneously with the leg cutting process, or may be performed immediately before or after the leg cutting process (simultaneously with the lip cutting process described below), or may be performed immediately after the lip cutting process. Also, the head cutting process may not be performed immediately after the leg cutting process, but may be performed before the leg cutting process or after the lip cutting process.

<Lip cutting process>
Next, as shown in Figures 10 and 11, while the leg cutting blades 21 are butted against each other in the leg cutting process state, the first cutting tool 25L and the second cutting tool 25R are lowered, whereby the lip portion 14 is cut by the lip cutting blade 22, and the unnecessary portions of the leg portion 12 and lip portion 14 are removed in a specified shape.

Once the unnecessary leg 12 and lip 14 portions have been cut off in the lip cutting process, the process returns to the initial state shown in FIG. 7. By repeating this series of steps, as shown in FIG. 12, it is possible to cut off the unnecessary leg 12 and lip 14 portions from the continuous molding 100 and simultaneously continuously manufacture roof moldings 10 of a predetermined length. If multiple dancer rollers are provided between the extrusion molding line and the cutting device 20 to provide a temporary stopping route for the supply to the cutting device 20, the cutting process by the cutting device 20 can be carried out smoothly.

When returning to the initial state from the lip cutting process, the first cutting tool 25L and the second cutting tool 25R can be raised while the leg cutting blades 21 are butted against each other, and then the first cutting tool 25L and the second cutting tool 25R can be retracted. However, it is preferable to retract the first cutting tool 25L and the second cutting tool 25R to separate the leg cutting blades 21 from each other, and then raise the first cutting tool 25L and the second cutting tool 25R. With the latter method, unnecessary scrap material 101 generated by the resection can be dropped reliably to the bottom.

In the above embodiment, the continuous molded product 100 is continuously supplied in the longitudinal direction from the extrusion molding machine, but the cutting device does not have to be arranged on the same line as the extrusion molding line. For example, the continuous molded product 100 may be extruded and cut to a fixed length, and then supplied to the cutting device 20. In this case, the cutting device 20 does not need to perform the head cutting process.
