Description

  The present invention relates to a heating device that heats a sheet-like material containing a thermoplastic resin or a fiber-reinforced thermoplastic resin, and a molding method using the heating device, before performing press processing by a press device.

In recent years, carbon fiber reinforced resin (hereinafter referred to as CFRP (carbon fiber reinforced plastic)) that is lightweight and excellent in strength has attracted attention in sports, industrial applications, and the like. For this reason, there is an increasing demand for technology for press molding using a fiber reinforced resin sheet having a thermoplastic resin as a base material.
In such press molding, after a fiber-reinforced resin sheet is preheated, it is conveyed to a press molding position of a press device and pressed (for example, see Non-Patent Document 1).

  For example, in Non-Patent Document 1, a radiant heating method using near infrared rays or far infrared rays is used as a preheating method before molding.

"Rectangular tube forming with thermoplastic CFRP sheet and strength / internal structure", 64th Plastic Processing Joint Lecture, Proceedings of 2013, P445-P446

However, the conventional method has the following problems.
That is, in the radiant heating used in the above-mentioned non-patent document, it is necessary to secure a certain distance between the heat source and the fiber reinforced resin sheet due to the problem of heating efficiency, and the radiant heating device becomes large and cannot be installed near the press device. . For this reason, the fiber-reinforced resin sheet preliminarily heated from the heating device to the press device has to be conveyed, and the temperature of the fiber-reinforced resin sheet is lowered during conveyance, and the moldability may be lowered.

  An object of this invention is to provide the heating apparatus which can suppress the temperature fall in conveyance to a press apparatus, and a shaping | molding method using the same.

  A heating device according to a first invention includes a first heating member, a second heating member, a first belt-like member, a second belt-like member, and a moving part. The first heating member is plate-shaped, and is disposed substantially in parallel with the sheet-like material above the sheet-like material when the sheet-like material containing the thermoplastic resin or the fiber-reinforced thermoplastic resin is heated. The material is heated. The second heating member has a plate shape, and is arranged below the sheet material and substantially parallel to the sheet material to heat the sheet material from below when heating. The first belt-like member is disposed between the first heating member and the sheet-like material during heating and is movable relative to the first heating member. The second belt-like member is disposed between the second heating member and the sheet-like material during heating and is movable relative to the second heating member. The moving unit moves the first heating member and the second heating member between a heating position for heating the sheet-like material and a discharge position for discharging the sheet-like material. As the first heating member and the second heating member move from the heating position to the discharge position, the first belt-like member moves relative to the first heating member, and the second belt-like member moves relative to the second heating member. The sheet material is relatively moved and discharged from between the first heating member and the second heating member.

Thereby, a sheet-like material can be arranged above the press processing position of a press device in the state where the 1st heating member and the 2nd heating member are in a heating position. And by moving the 1st heating member and the 2nd heating member to a discharge position, the 1st heating member and the 2nd heating member can be moved from the upper part of a press processing position, and a sheet-like material can be mounted in a press processing position. .
For this reason, it is possible to shorten the time until the sheet material is placed from the heating device to the press processing position, and it is possible to suppress a decrease in temperature during conveyance.

Note that the upper position of the press working position is, for example, between the upper mold and the lower mold, and the press working position is, for example, above the lower mold.
In addition, in the radiant heating, since heating is performed in an air atmosphere, when the resin temperature rises, the resin and oxygen are combined to generate smoke, which may deteriorate the resin and deteriorate the working environment. In the heating device of the invention, since the sheet-like material is heated in a state covered with the first belt-like member and the second belt-like member, the contact between the air and the resin during heating can be reduced. For this reason, since deterioration of resin can be suppressed and generation | occurrence | production of the smoke by the contact of air and resin can also be suppressed, a working environment can be made favorable.
Further, since the sheet-like material is supported by surface contact, it is easy to hold and convey even a material whose shape at the time of melting such as discontinuous fibers is unstable.

(2-1. Operation of heating device main body)
Next, the operation of the heating apparatus body 2 will be described with reference to FIGS. 4 (a) to 4 (c).

FIG. 4A is a diagram illustrating a state in which the stampable sheet S is heated by the heating device 1.
In the heating state, the first heater plate 41 and the second heater plate 42 are disposed at a heating position protruding forward by the moving unit 23. The stampable sheet S is sandwiched between the first heater plate 41 and the second heater plate 42 via the first belt-like member 43 and the second belt-like member 44.

Thus, the stampable sheet S is heated by the first heater plate 41 and the second heater plate 42 in surface contact via the first belt-like member 43 and the second belt-like member 44.
Next, when the stampable sheet S is discharged from between the first heater plate 41 and the second heater plate 42, the handle 23c is rotated and the rear end frame 63 moves rearward (in the direction of arrow A2). By the movement of the rear end frame 63, the first left frame 61a, the first right frame 61b, the second left frame 62a, and the second right frame 62b fixed to the rear end frame 63 move rearward.

Since the position is fixed with respect to the left slide mounting member 226 and the right slide mounting member 225, the position does not move with the first heater plate 41 and the second heater plate 42.

  Therefore, as the first heater plate 41 and the second heater plate 42 move, the first belt-like member 43 rotates and moves relative to the first heater plate 41 with the belt portion 43a being fixed. (See arrow D). Further, as the first heater plate 41 and the second heater plate 42 move, the second belt-like member 44 rotates and moves relative to the second heater plate 42 with the belt portion 44a being fixed. (See arrow E).

  Thus, as the first heater plate 41 and the second heater plate 42 move rearward, the first belt-like member 43 and the second belt-like member 44 are replaced by the first heater plate 41 and the second heater plate 42. The stampable sheet S is discharged by rotating relative to the. 4A to 4C, it can be seen that the belt portion 43a and the belt portion 44a are fixed at the position of the line F.

  When the first heater plate 41 and the second heater plate 42 are further moved rearward by the moving unit 23 from the state of FIG. 4B, the first heater plate 41 and the second heater plate 42 are shown in FIG. Thus, the stampable sheet S is completely discharged from between the first heater plate 41 and the second heater plate 42. FIG. 6 shows a perspective view of the heating apparatus main body 2 in a state where the first heater plate 41 and the second heater plate 42 are arranged at the discharge position.

  When the stampable sheet S is sandwiched between the first heater plate 41 and the second heater plate 42, the stampable sheet S is disposed at the front position of the heating device body 2 as shown in FIG. Then, the first heater plate 41 and the second heater plate 42 may be moved forward (arrow A1) by the moving unit 23.

FIG. 8 is a diagram showing a flow of a molding method using the heating device 1 and the press device 100 of the present embodiment.

  First, as shown in FIG. 7A, the stampable sheet S is sandwiched between the first heater plate 41 and the second heater plate 42 (step S10). Note that, as described above, the stampable sheet S is sandwiched in the front position of the heating apparatus body 2 and the first heater plate 41 and the second heater plate 42 are moved forward as described above.

Next, the stamper sheet S is heated by energizing the first heater plate 41 and the second heater plate 42 (step S20). The first heater plate 41 and the second heater plate 42 may be energized before the stampable sheet S is sandwiched.
Next, as shown in FIG. 7B, the heating device main body 2 is moved along the rail members 31 and 32 toward the press device 100, and the stampable sheet S is heated (first heater plate). 41 and the second heater plate 42 are arranged in the heating position), and are arranged between the upper mold 106 and the lower mold 107 (step S30).

Next, it is determined whether or not the temperature of the stampable sheet S has risen to a temperature suitable for press working. If not, the heating device 1 stands by in the state of FIG. Note that the temperature rise may be determined by the heating time or the temperature may be measured.
Next, when the temperature of the stampable sheet S rises to a temperature suitable for press working, the stampable sheet S is discharged from between the first heater plate 41 and the second heater plate 42 (step S40). With this discharge, the stampable sheet S is placed on the lower mold 107 as shown in FIG. Further, this discharge is the same as the operation described in FIGS. 4 (a) to 4 (c).
Next, as shown in FIG.7 (d), the heating apparatus main body 2 moves back (arrow A2 direction) from the press apparatus 100 (step S50).
Subsequently, the upper mold 106 is lowered by the lowering of the slide 104, and press working is performed between the upper mold 106 and the lower mold 107 (step S60).

The heating device 1 of the above embodiment includes a first heater plate 41 (an example of a first heating member), a second heater plate 42 (an example of a second heating member), a first belt-like member 43, and a second A belt-like member 44 and a moving part 23 are provided. The first heater plate 41 has a plate shape, and is disposed above the stampable sheet S substantially in parallel with the stampable sheet S when the stampable sheet S (an example of a sheet-like material) is heated, and is stamped from above. The bull sheet S is heated. The second heater plate 42 has a plate shape, and is disposed below the stampable sheet S in parallel with the stampable sheet S when heated, and heats the stampable sheet S from below. The first belt-like member 43 is disposed between the first heater plate 41 and the stampable sheet S during heating and is relatively movable with respect to the first heater plate 41. The second belt-like member 44 is disposed between the second heater plate 42 and the stampable sheet S during heating and is relatively movable with respect to the second heater plate 42. The moving unit 23 moves the first heater plate 41 and the second heater plate 42 between a heating position for heating the stampable sheet S and a discharge position for discharging the stampable sheet S. As the first heater plate 41 and the second heater plate 42 move from the heating position to the discharge position, the first belt-like member 43 moves relative to the first heater plate 41, and the second belt-like member 44 moves to the second position. The stampable sheet S moves relative to the heater plate 42 and is discharged from between the first heater plate 41 and the second heater plate 42.

  Accordingly, the stampable sheet S can be disposed above the press processing position of the press device 100 in a state where the first heater plate 41 and the second heater plate 42 are in the heating position. Then, by moving the first heater plate 41 and the second heater plate 42 to the discharge position, the first heater plate 41 and the second heater plate 42 are moved from above the pressing position, and the stampable sheet S is pressed.
