Description

  The present invention relates to a transport pallet, a take-out method for taking out a softened fiber reinforced resin from the transport pallet, and a press set. More specifically, the present invention relates to a transport pallet for transporting a softened fiber reinforced resin, from the transport pallet after transport. The present invention relates to a take-out method for taking out a softened fiber reinforced resin and a press set for pressing the softened fiber reinforced resin.

In order to achieve reduction of exhaust gas and improvement of fuel consumption, weight reduction of the vehicle body is being studied in vehicles and the like.
For example, conventionally, heavy iron has been mainly used for exterior parts for vehicles such as bonnets, bumpers, doors, etc. In recent years, as an alternative material, a fiber reinforced resin that is lightweight and excellent in strength is used. Attention has been paid.

  By the way, in order to use the fiber reinforced resin as an exterior part for a vehicle, it is necessary to deform the softened fiber reinforced resin into a desired shape by pressing or the like, but the softened fiber reinforced resin also depends on its own weight. Since it is easy to deform and does not involve magnetism, there is a problem that it cannot be transported by a robot, a magnetic conveyor, or the like as in the case of a conventional iron work.

  On the other hand, a conveying device for a carbon fiber-containing resin sheet that chucks (grasps) both ends of a carbon fiber-containing resin sheet heated in a heating furnace, applies tension to the carbon fiber-containing resin sheet, and conveys it to a press device. It is known (see, for example, Patent Document 1).

JP 2013-99932 A

However, in the conveying device described in Patent Document 1, since the both ends of the carbon fiber-containing resin sheet are gripped and conveyed while applying tension, the carbon fiber-containing resin sheet to be conveyed has a certain strength even if it is softened. And has a disadvantage that it is limited to a relatively light weight that is not deformed by its own weight.
In other words, if the strength when softening the carbon fiber-containing resin sheet is weak, there is a risk of tearing by applying tension, and if the weight of the carbon fiber-containing resin sheet is large, both ends thereof are gripped Further, there is a possibility that resin sag occurs during transportation due to the weight of the carbon fiber-containing resin sheet.
In addition, even if it is a case where a lightweight carbon fiber containing resin sheet is used, if it is too soft, there is a possibility that resin sagging may occur in the same manner, and therefore it is necessary to maintain and manage an appropriate softened state.
Moreover, since the site | part by which the resin sheet containing carbon fiber was gripped cannot be used as a product, there also exists a fault that it becomes a waste material and a yield rate worsens.

  The present invention has been made in view of the above circumstances, and is capable of preventing resin sag and tearing regardless of the physical properties of the fiber reinforced resin, easily transporting the softened fiber reinforced resin, and yield.

(First embodiment)
Next, a first embodiment of the transport pallet according to the present invention will be described.
FIG. 1 is a side view schematically illustrating a state in which a softened fiber reinforced resin is placed on a conveyance pallet according to the first embodiment.
As shown in FIG. 1, the transport pallet 1 according to the first embodiment includes an endless belt 10 and a lower frame body 11 having a pair of rolls 11 a on which the endless belt 10 is stretched.
A softened fiber reinforced resin X is placed on the endless belt 10.

In the transport pallet 1 according to the first embodiment, the softened fiber reinforced resin X is transported on the upper surface of the endless belt 10.
At this time, since the endless belt 10 supports the softened fiber reinforced resin X, the softened fiber reinforced resin X can be easily conveyed regardless of the physical properties of the fiber reinforced resin X.
In addition, it is possible to prevent resin sag and tearing based on the weight of the softened fiber reinforced resin X, and by making the degree of softening of the fiber reinforced resin X softer, the burden for maintaining and managing the softened state Can also be reduced.
Furthermore, since the conveyance pallet 1 does not grip both ends of the softened fiber reinforced resin X, there are very few parts that become waste materials, and the yield rate can be improved.

The fiber reinforced resin X consists of fibers, such as glass fiber or carbon fiber, and thermoplastic resins, such as polyamide and polypropylene, and these can be adopted and manufactured by a known method.
Among these, when manufacturing exterior parts for vehicles from fiber reinforced resin X, it is preferred to use carbon fiber as fiber of fiber reinforced resin X from a viewpoint of intensity and weight reduction. That is, it is preferable to use a so-called carbon fiber reinforced composite material (CFRTP) as the fiber reinforced resin X. Such CFRTP may be an isotropic CFRTP intermediate substrate or a unidirectional CFRTP intermediate substrate.

In the fiber reinforced resin X, it is preferable to employ short fibers or chopped fibers. In this case, the flat fiber reinforced resin X can be easily deformed into a desired shape by, for example, pressing the softened fiber reinforced resin X.
In addition, by using inexpensive short fibers or chopped fibers, it is possible to manufacture vehicle exterior parts and the like using the fiber reinforced resin X at a low cost.
It should be noted that fiber reinforced resin using short fibers or chopped fibers generally has low strength when softened, and resin sag and tear are likely to occur. However, as described above, the fiber reinforced resin was always placed on the transport pallet 1. By setting the state, it is possible to prevent the sagging and tearing of the resin, so that the softened fiber reinforced resin X can be reliably conveyed even when short fibers or chopped fibers are used.

  The endless belt 10 has a loop shape in a side view. That is, the endless belt 10 has an upper portion 10a and a lower portion 10b between the pair of rolls 11a. The fiber reinforced resin X is placed on the upper surface of the upper portion 10a.

Here, the material of the endless belt 10 is made of metal from the viewpoint of heat resistance. The metal is not particularly limited, and examples thereof include stainless steel.
The surface shape of the endless belt 10 is preferably a mesh shape. The shape of the mesh is not particularly limited. That is, when the endless belt 10 is a mesh-like metal belt, the fiber reinforced resin X before being softened is heated together with the conveying pallet 1 while being placed on the endless belt 10, thereby the fiber reinforced resin X Can be softened.
Moreover, since the contact area with the softened fiber reinforced resin X will become small if the endless belt 10 is mesh shape, after conveying the softened fiber reinforced resin X, it can be easily taken out from the conveyance pallet 1. It becomes.

In the resin pallet 1, a contact portion 15 protruding downward is fixed to a side portion of the upper portion 10 a of the endless belt 10.
The endless belt 10 is configured to rotate based on the slide of the transport pallet 1 by bringing the contact portion 15 into contact with a stopper (not shown) described later and sliding the transport pallet 1. That is, the endless belt 10 can be rotated without using a special power source.
By rotating the endless belt 10, the softened fiber reinforced resin X is taken out as will be described later.

The lower frame 11 includes a pair of front and rear rolls 11a and a pair of left and right side bars 11b that support both ends of the roll 11a so as to be perpendicular to the transport direction of the transport pallet 1.
The endless belt 10 described above is stretched between the pair of rolls 11a.

In the lower frame 11, a protrusion 11c for hooking a moving hook (not shown) described later is provided at the tip of the side bar 11b.
In addition, the conveyance pallet 1 slides simultaneously by sliding a movement hook in the state which hooked the movement hook in the projection part 11c.

In the lower frame 11, the roll 11 a and the side bar 11 b are supported by a support bar 12 that extends vertically, and the support bar 12 is placed on a thin plate-like sled 13.
Such a sled 13 has a bottom surface that is easy to slide, and plays a role of assisting the slide of the transport pallet 1.

Next, a fiber reinforced resin transport method using the transport pallet 1 will be described.
First, the fiber reinforced resin X before being softened is placed on the endless belt 10 of the transport pallet 1.
FIG. 2 is a side view schematically showing an example of a method for heat-softening the fiber reinforced resin in the transport pallet according to the first embodiment.
As shown in FIG. 2, in the conveyance pallet 1, in a state where the fiber reinforced resin X before softening is placed on the endless belt 10, the whole is put into the heating furnace H as it is to soften the fiber reinforced resin X. . Thereby, the operation | work of mounting the fiber reinforced resin X of the softened state which is hard to handle on the endless belt 10 can be omitted.

  At this time, as described above, since the endless belt 10 is made of a mesh-like metal belt, the fiber reinforced resin X is not prevented from being heated by the heating furnace H from below. That is, since the fiber reinforced resin X can be heated uniformly from above and below, the fiber reinforced resin X can be uniformly softened.

Next, a method for sliding the transport pallet 1 will be described.
FIG. 3 is a side view schematically showing an example of a method for sliding the transport pallet according to the first embodiment.
First, in the method of sliding the transport pallet 1, the softened fiber reinforced resin X is placed on the endless belt 10, and the protrusion 11 c provided at the tip of the side bar 11 b of the lower frame body 11 is applied. The moving hook 18 is hooked.
Then, as shown in FIG. 3, the transport pallet 1 is integrated with the moving hook 18 by sliding the moving hook 18 in the state where the moving hook 18 is hooked on the protrusion 11 c (in the direction of the arrow in FIG. 3). It comes to slide. In addition, since the warp 13 is provided in the conveyance pallet 1, the conveyance pallet 1 slides smoothly.
In this way, the transport pallet 1 can be slid with simple equipment.

Next, a method for taking out the fiber reinforced resin X from the transport pallet 1 will be described.
(A)-(c) of Drawing 4 is a side view showing roughly the taking-out method which takes out the softened fiber reinforced resin from the conveyance pallet concerning a 1st embodiment.
In the method of taking out the fiber reinforced resin X from the conveyance pallet 1, first, the conveyance pallet 1 is slid by sliding the movement hook 18 in a state where the movement hook 18 is hooked on the projecting portion 11c. As shown to (a), the contact part 15 of the conveyance pallet 1 is made to contact | abut to the stopper 17 provided in the both sides of the extraction area | region P which takes out fiber reinforced resin. The structure of the stopper 17 will be described later.

As a result, the upper portion 10a of the endless belt 10 is restrained at that position by the stopper 17 via the contact portion 15. Therefore, when the transport pallet 1 is further slid, FIG. As shown, the endless belt 10 rotates.
At this time, the fiber reinforced resin X placed on the upper surface of the upper portion 10a is conveyed along with the rotation of the endless belt 10, and finally falls into the take-out area P as shown in FIG. Will do.
Thus, in the take-out method for taking out the fiber reinforced resin X from the transport pallet 1, the softened fiber reinforced resin can be taken out by a simple method and can be easily arranged in the take-out region P.

Here, the structure of the stopper 17 will be described.
(A)-(c) of FIG. 5 is a top view for demonstrating the structure of a stopper in the taking-out method which takes out the softened fiber reinforced resin from the conveyance pallet which concerns on 1st Embodiment.
As shown in FIGS. 5A to 5C, a pair of stoppers 17 are provided on both the left and right sides of the take-out area P with respect to the transport direction of the transport pallet 1.
Both stoppers 17 are rotary claw-type stoppers, and include a shaft portion 17a and a claw portion 17b attached to the shaft portion 17a.

  On the other hand, the transport pallet 1 is provided with outer frames 16b on both outer sides of the lower frame body 11 via support portions 16a. The top view extends in the longitudinal direction of the outer frame 16b on the inner side of the outer frame 16b. A trapezoidal cam bar 16 is provided. The outer frame 16b is also placed on a warp (not shown).

As shown in FIG. 5A, before the contact portion 15 of the transport pallet 1 contacts the claw portion 17b of the stopper 17, the claw portion 17b is located in front of the contact portion 15 (right side in the drawing). Located in.
When the transport pallet 1 is slid by the moving hook 18 and the transport pallet 1 comes to a predetermined position, as shown in FIG. 5B, the cam bar 16 comes into contact with the shaft portion 17a, and the shaft portion 17a is moved. Rotate. In addition, the state after rotation of the shaft portion 17a is maintained by the length of the cam bar 16.
Since the claw portion 17b protrudes toward the transport pallet 1 by the rotation of the shaft portion 17a, the abutment portion 15 abuts on the claw portion 17b and stops at that position.

As described above, by sliding the transport pallet 1, the endless belt 10 rotates and the fiber reinforced resin X is taken out.
After the fiber reinforced resin X is taken out, as shown in FIG. 5 (c), the cam bar 16 and the shaft portion 17a are not in contact with each other, and the rotating shaft portion 17a has a spring restoring force (not shown). Thus, the claw portion 17b is disposed at the original position where it does not contact the contact portion 15.
As described above, in the method of taking out the fiber reinforced resin from the transport pallet, the stopper 17 is a rotary claw type, and the cam bar 16 that rotates the shaft portion 17a of the stopper 17 is provided on the transport pallet 1, thereby providing a special power source. The stopper 17 and the abutting portion 15 can be brought into contact with each other without using.

Next, a press set including the transport pallet 1 and a press device will be described.
FIG. 6 is a side view for explaining a press set including the transport pallet and the press device according to the first embodiment.
As shown in FIG. 6, the press device 3 is attached via a bed 31, a crown 33 supported by four uprights 32 provided on the bed 31, and a slide 34 connected to the crown 33. The upper die 3a, the lower die 3b attached via a bolster 35 disposed on the bed 31, a pair of roller bases 36 provided on both sides of the bolster 35 on the bed 31, and adjacent uprights. A rail 37 bridged to 32, a moving hook 38 attached via a slider 37 a that slides on the rail 37, and a stopper 17 provided on the bolster 35.

In the press set, the transport pallet 1 is heated, for example, in a heating furnace adjacent to the press device 3.
And the conveyance pallet 1 can be conveyed with the conveyance pallet 1 like the method of sliding the conveyance pallet 1 mentioned above. That is, the conveyance pallet 1 is slid by hooking the moving hook 38 on the protrusion 11 c of the conveyance pallet 1 and sliding the slider 37 a along the rail 37. In addition, at this time, since the conveyance pallet 1 is supported by a pair of roller stand 36, it slides so that it may slide on the roller stand 36 via a warp.

  In addition, the softened fiber reinforced resin X can be taken out onto the lower mold 3b in the same manner as the above-described method for taking out the softened fiber reinforced resin X from the transport pallet 1. That is, the endless belt 10 is rotated by causing the abutting portion 15 of the conveying pallet 1 to abut against the stopper 17 provided on the bolster 35 while the conveying pallet 1 is slid, and further sliding the conveying pallet 1. Then, the fiber reinforced resin X is taken out on the lower mold 3b.

Thus, according to the press set, even the sufficiently softened fiber reinforced resin X can be transported, and by using the press device 3 corresponding to the transport pallet 1, the softened fiber reinforced resin X Can be pressed.
Thus, even a relatively large fiber reinforced resin X can be molded into a desired shape by using a press set, and is used for exterior parts for vehicles such as bonnets, bumpers, doors, and the like. It becomes possible.

(Second Embodiment)
Next, a second embodiment of the transport pallet according to the present invention will be described.
FIG. 7 is a side view schematically showing a state in which the softened fiber reinforced resin is placed on the transport pallet according to the second embodiment.
As shown in FIG. 7, the conveyance pallet 2 according to the second embodiment includes an endless belt 10, a lower frame 11 having a pair of rolls 11a on which the endless belt 10 is stretched, an auxiliary endless belt 20, An upper frame body 21 having a pair of rolls 21a on which the auxiliary endless belt 20 is stretched, and a connecting portion 40 that connects the upper frame body 21 and the lower frame body 11 are provided.
The softened fiber reinforced resin X is placed on the endless belt 10, and the auxiliary endless belt 20 is further arranged on the softened fiber reinforced resin X.
That is, it is the same as the transport pallet 1 according to the first embodiment except that the auxiliary endless belt 20, the upper frame body 21, and the connecting portion 40 are further provided.

In the transport pallet 2 according to the second embodiment, the softened fiber reinforced resin X is transported between the auxiliary endless belt 20 and the endless belt 10.
At this time, since the endless belt 10 supports the softened fiber reinforced resin X, the softened fiber reinforced resin X can be easily conveyed regardless of the physical properties of the fiber reinforced resin X.
In addition, it is possible to prevent resin sag and tearing based on the weight of the softened fiber reinforced resin X, and by making the degree of softening of the fiber reinforced resin X softer, the burden for maintaining and managing the softened state Can also be reduced.
Furthermore, since the conveyance pallet 2 does not grip both ends of the softened fiber reinforced resin X, there are very few parts that become waste materials, and the yield rate can be improved.

  The auxiliary endless belt 20 has a loop shape in a side view, like the endless belt 10 described above. That is, the auxiliary endless belt 20 has an upper portion 20a and a lower portion 20b between the pair of rolls 21a.

Here, the auxiliary endless belt 20 is made of metal from the viewpoint of heat resistance. The metal is not particularly limited, and examples thereof include stainless steel.
The surface shape of the auxiliary endless belt 20 is preferably a mesh shape. The shape of the mesh is not particularly limited. That is, when the endless belt 20 is a mesh-like metal belt, the fiber reinforced resin X before softening is heated together with the conveying pallet 2 while being sandwiched between the auxiliary endless belt 20 and the endless belt 10. Thus, the fiber reinforced resin X can be softened.
Moreover, since the contact area with the softened fiber reinforced resin X will become small if the auxiliary endless belt 20 is mesh shape, after conveying the softened fiber reinforced resin X, the auxiliary endless belt 20 and the endless belt 10 Can be easily removed from the transport pallet 2.

In the resin pallet 2, a connecting portion 25 extending upward so as to be continuous with the contact portion 15 is attached to a side portion of the upper portion 10 a of the endless belt 10.
The connecting portion 25 is also attached to the side portion of the lower portion 20 b of the auxiliary endless belt 20.
That is, the auxiliary endless belt 20 and the endless belt 10 are connected by the connecting portion 25.
Thus, the auxiliary endless belt 20 and the endless belt 10 are synchronized with each other based on the slide of the transport pallet 2 by causing the contact portion 15 to contact a stopper (not shown) and sliding the transport pallet 2. It is designed to rotate. That is, the auxiliary endless belt 20 and the endless belt 10 can be rotated without using a special power source.

The upper frame 21 includes a pair of front and rear rolls 21a and a pair of left and right side bars 21b that support both ends of the roll 21a so as to be perpendicular to the transport direction of the transport pallet 2.
The endless belt 10 is stretched between the pair of rolls 21a.

FIG. 8 is a side view schematically showing a state where the auxiliary endless belt is opened in the transport pallet according to the second embodiment.
In the transport pallet 2, the connecting portion 40 connects the upper frame body 21 and the lower frame body 11.
At this time, the upper frame body 21 is pivotally attached to one end of the connecting portion 40, and the lower frame body 11 is fixed to the other end of the connecting portion 40.
For this reason, by rotating the upper frame 21 around the connecting portion 40 with respect to the lower frame 11, the auxiliary endless belt 20 and the endless belt 10 can be opened and closed as shown in FIG. 8. it can.
Therefore, for example, when the upper frame body 21 is turned upward, the softened fiber reinforced resin X can be easily placed on the endless belt 10, and the upper frame body 21 is moved downward. By rotating and returning to the original position, the softened fiber reinforced resin X can be held between the auxiliary endless belt 20 and the endless belt 10.

Regarding the method of taking out the fiber reinforced resin X from the transport pallet 2, the fiber reinforced resin X is transported from the transport pallet 1 described above in that the fiber reinforced resin X is transported along with the rotation of the auxiliary endless belt 20 and the endless belt 10. It is different from the extraction method.
As described above, in the method of taking out the fiber reinforced resin X from the transport pallet 2, after the softened fiber reinforced resin X is transported to a desired position, the auxiliary endless belt 20 and the endless belt 10 are rotated in synchronization. Therefore, the softened fiber reinforced resin X can be taken out more easily and smoothly.

  In addition, about the press set which consists of the conveyance method of the fiber reinforced resin using the conveyance pallet 1, the method of sliding the conveyance pallet 1, and the conveyance pallet 1 and a press apparatus mentioned above, the conveyance pallet which concerns on 1st Embodiment. It is possible to replace 1 with the transport pallet 2 according to the second embodiment.
