BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blade receiving device for a cutting blade in a sheet cutter.

[0002]

2. Description of the Related Art Conventionally, SMC (sheet molding compound) has been widely used as a molding material for producing reinforced plastic products such as bathtubs. This SMC is obtained by adding a reinforcing material such as chopped strands, a filler, and a thickener to a liquid unsaturated polyester resin to lose fluidity and form a sheet, and has adhesiveness. For this reason, as shown in FIGS. 4 and 5, the normal SMC1 is formed on the SMC sheet 1S by covering the upper and lower surfaces thereof with films 2 and 2 made of polyethylene or the like having a width larger than the width of the SMC1. SMC
The sheet 1S is wound around the core tube 3 to form an SMC roll body 1R.

On the other hand, when molding a reinforced plastic product, the SMC roll 1R is
After the sheet 1S is fed out and the films 2 and 2 of the SMC sheet 1S are peeled off, the SMC 1 is cut to a set length, and the cut SMC (hereinafter, referred to as cut SMC).
A sheet cutter 10 that supplies 1a to a subsequent stage is used.

First, the sheet cutter 10 will be described. As shown in FIG.
A pedestal 11 that rotatably supports the core tube 3 of the SMC roll body 1R, and an S that is supported and pulled out by the pedestal 11
A pair of pinch rolls 12, 12 which sandwich the MC sheet 1S from above and below and feed it out downstream;
Winding rolls 13 and 13 for winding the films 2 and 2 peeled off on the feeding sides of the SMCs 2 and 12 and a cutting blade 14 for cutting the SMC 1 in the left-right width direction (the direction perpendicular to the plane of FIG. 5).
It is composed of

[0005] Further, the above-mentioned cradle 11 and pinch roll 1
A guide roll 16 for guiding the SMC sheet 1S onto the connection table 15 is provided between the rollers 2 and 12.

A drive motor (not shown) is connected to the lower pinch roll 12, and a gear transmission mechanism (not shown) is provided between the upper and lower pinch rolls 12. The SMC sheet 1S is sandwiched by the upper and lower pinch rolls 12 and 12 while being rotated in the opposite directions to be fed out downstream.

On the other hand, the cutting blade 14 is fixed to a holder 14a. By moving the holder 14a along a guide beam (not shown) provided in the width direction of the SMC 1, a blade holder fixed to the connection table 15 is provided. Body 1
The SMC 1 can be cut to any length between the blade receiving groove 7 and the SMC 1.

Reference numeral 18 denotes a sheet cutter conveyer provided on the connection table 15 of the sheet cutter 10 so that the conveying surface thereof is continuous, and the cut SMC 1a cut by the cutting blade 14 of the sheet cutter 10 is moved to a predetermined position. To be transported.

[0009]

Since the above-mentioned blade receiving body guides the cutting blade while supporting the SMC, resin paste of the SMC and debris generated at the time of cutting the SMC adhere. Therefore, when the SMC is changed, such as when the type is changed, it is necessary to clean the blade receiving body in order to prevent the color of the SMC to be newly formed from mixing with the color of the previous SMC to cause a defective product. . In cleaning such a blade receiving body, the sheet cutter must be stopped for a long time, and there has been a problem that the working efficiency is reduced.

[0010] The present invention has been made in view of such a problem, and when the SMC is changed, the SM is required.
An object of the present invention is to provide a blade receiving device for a cutting blade in a sheet cutter, which can prevent the occurrence of defective products due to mixing of C without lowering the working efficiency.

[0011]

According to the present invention, there is provided a pair of pinch rolls for sandwiching an SMC sheet from above and below and feeding them out to a connection table, and SMs fed from the pinch rolls.
In a sheet cutter having at least a cutting blade for cutting C and a blade receiving body formed with a blade receiving groove for accommodating the cutting blade, the blade receiving body is fitted and disengaged from a supporting portion formed on a frame of a connection table. The blade receiving body is freely supported, and is configured so that the blade receiving body of the new blade receiving groove can be inserted and supported by pulling out the blade receiving body from the supporting portion and detaching it.

[0012]

When changing the SMC, the operation of the sheet cutter is stopped, and the blade receiving body of the blade receiving groove used so far is pulled out from the supporting portion formed on the connection table and detached. The blade receiving body of the receiving groove is inserted into the supporting portion to be supported.

As described above, since the blade receiving groove can be easily replaced with a new blade receiving groove, occurrence of defective products due to the incorporation of SMC is prevented, and it becomes unnecessary to stop the sheet cutter and clean the blade receiving body. There is no reduction in work efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG.

Frame 15 constituting connection table 15
1, a notch 15a is formed in the left-right width direction, and a holding plate 152 is attached so as to cover the notch 15a. Then, the notch 15 of the frame 151
a and a holding plate 152, the blade receiving body 17 described later.
A support portion is formed.

On the other hand, as shown in FIG. 2, the blade receiving main body 17A has a blade receiving groove 17a which can accommodate and pass the cutting blade 14 in the center thereof and extends in the left-right width direction. Is provided with rails 17b, 17b corresponding to the above-described support portions, and is formed in a generally duck shape in cross section. Further, immediately below the blade receiving groove 17a, the cutting blade 14 is provided.
A slit 17c having a predetermined width is formed in correspondence with the cutting stroke of the above, so that scrap generated at the time of cutting is dropped downward. A handle 17d is attached to the tip of the blade receiving body 17A.

Accordingly, from the side of the sheet cutter 10, the rail 1 of the blade receiving body 17A is inserted into the support formed by the notch 15a of the frame 151 and the holding plate 152.
7b and 17b are fitted and pushed in, so that the cutting blade 1
4 is received in the blade receiving groove 17a while the connection table 15 is
The blade receiving body 17A can be inserted into the main body. In this state, the blade receiving body 17A is supported by the support formed on the connection table 15 by its frictional force,
The cutting operation of the SMC 1 can be performed by the cutting blade 14.

Next, when changing to the SMC 1 of a different color, the blade receiving body 17A is pulled out along the supporting portion while holding the handle 17d, and a new blade which has previously cleaned the blade receiving groove 17a. By inserting the receiving main body 17A as described above, a new blade receiving main body 17A can be supported.

At this time, the blade receiving body 17 as shown in FIG.
B can also be used. The blade receiving body 17B has a plurality of blade receiving grooves 17a formed vertically, and after using one blade receiving groove 17a, it can be turned upside down to use the other blade receiving groove 17a. With this configuration, it is possible to reduce the storage space of the blade receiving body 17A and to reduce the number of payouts.

[0020]

As described above, according to the present invention, the blade receiving body having the blade receiving groove is inserted and supported in the supporting portion formed on the frame of the connection table, and the blade receiving body is appropriately pulled out. Since the blade receiving groove can be replaced with a new blade receiving groove, it is possible to easily and quickly replace the blade receiving groove when changing the SMC.
In addition to preventing the occurrence of defective products due to the incorporation of MC,
It is not necessary to stop the sheet cutter and clean the blade receiving body for a long time, and there is no reduction in work efficiency.
