2. Description of the Related Art Generally, in order to attach a sheet material such as a rubber vibration isolator to an adherend such as an iron plate, a cutting machine such as a press or a laser and a pressure bonding machine are separately used. That is, in FIG. 6, first, the sheet material A such as a rubber vibration isolator is applied to the cutting press machine 101, and the sheet material A is punched by the cutting blade 103. Since the cut sheet material C adheres to the inside of the cutting blade 103, it is taken out by a method such as suction and conveyed to the pressure bonding press machine 102. The adherend B is placed on the fixed die 104 of the crimping press machine 102, the sheet material C is placed thereon, and the movable die 105 is lowered to perform crimping.

[0003]

In the above method, the cutting step and the crimping step are separate, so that there is a work-in-process product (work-in-process) between the cutting step and the crimping step, and a space for storage thereof. Since it requires time and effort for transportation and insertion and unloading work are required for both the cutting machine and the crimping machine, there is a problem that it is twice as laborious. Further, in consideration of automation, if the sheet material C is a soft material, automatic insertion and automatic punching become more difficult, and if it is extremely soft, adhesion of an adherend fixed to the pressure bonding press machine 102 It is very difficult to position and place the sheet material C on a place, and if the adherend B is an iron plate that is deformed by a little stress, positioning is almost impossible. Further, if the sheet material C has a hole or a net-like shape, the sheet material C stuck to the cutting blade 103 of the cutting press 101 cannot even be sucked and pulled out. Have

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to cut and crimp in the same step, which is conventionally impossible to handle. An object is to provide an automatic cutting and bonding machine that can automatically cut and crimp soft materials such as wood and net materials.

Next, the sheet material feeding and cutting apparatus of the present invention will be described. FIG. 2 is a perspective sectional view of a main part of the sheet material feeding and cutting apparatus, which includes a cutting blade 6, a feeding plate 8, a pressing plate 9 and a gripping piece 12. FIG. 3 is a side sectional view showing the sheet material feeding and cutting device and the crimping means 3, and FIGS. 4 and 5 are views showing the operation thereof.

The cutting blade 6 is mounted on the outer periphery of the hole 13a of the frame 13 provided for the movable die 5 to penetrate, with the blade facing upward, and this is the cutting range a in FIG. .

The feed plate 8 is a flat plate having a bent portion 8a, and a round hole 8c is formed in the center of the bent portion 8a and a flat hole 8c is formed in the flat portion 8b.
A long hole 8d for a book is provided. These two long holes 8d
Is a clamper 1 for attaching / detaching the feed plate 8 to / from the pressing plate 9.
0 is inserted, the distance between the two elongated holes 8d is larger than the width L of the sheet material A, and is formed so as to just follow the side of the sheet material A. One of the spring shafts 14 is inserted. As shown in FIG. 3, the other one of the spring shafts 14 is connected to a movable roller 17 having a roller 16 and urging the roller 16 with a spring 18 against the feed plate 8. The spring 15 is held between the bent portion 8a and
When the feed plate 8 advances to the right in the drawing, it is biased to the left, and when the clamper 10 is released, the feed plate 8 is retracted to the left. Further, as shown in FIG. 3, the size of the flat surface portion 8b of the feed plate 8 is a size that sufficiently covers the cutting range a of the cutting blade 6, and the pressing plate 9 has the same size or a size that covers it. By operating the clamper 10, the sheet material A is pressed and sandwiched between the pressing plate 9 and the feeding plate 8 and fed to the cutting range a. Also, the feed plate 8
Is attachable to and detachable from the pressing plate 9, and when the pressing plate 9 is in the cutting range a, the clamper 10 is released to release the spring 15
By urging, the feed plate 8 alone can be retracted to the retreat range b. At that time, since the feed plate 8 retreats while stroking the surface of the sheet material A, the sheet material A is held on the lower surface of the pressing plate 9 in a taut state, and the pull-down plate cylinder 31 is driven to drive the pull-down plate. The sheet material A held on the lower surface of the pressing plate 9 is die-cut by lowering 11 and pressing the pressing plate 9 against the cutting blade 6.

The holding plate 9 is a pull-down plate 11 shown in FIG.
It is connected to a cylinder rod 32a of a feed cylinder 32 provided below, and can advance and retreat between a cutting range a and a retreat range b. A down rod 19 is attached to each of the four corners of the pull-down plate 11, and the pull-down plate cylinder 3
When the rod 31a of No. 1 is extended, the descending rod 19 descends and the pressing plate 9 descends. When the rod 31a is contracted, the descending rod 19 rises, and the spring 33 restores the pull-down plate 11 and the pressing plate 9.

The gripping piece 12 is attached at the position shown in FIG. 3 so that the leading end of the sheet material A which is sandwiched between the feed plate 8 and the pressing plate 9 and fed into the cutting range a can be grasped. This may be two or more rod-shaped members or one plate-shaped member, and is lifted and lowered by the gripping piece driving device 34. Then, the pressing plate 9 advances into the cutting range a,
The feeding plate 8 rises at the moment of retreating, and the front end of the sheet material A held on the lower surface of the pressing plate 9 is sandwiched between the pressing plate 9 and grasped.

Next, the operation of the above-described sheet material feeding and cutting device will be described with reference to FIGS. 3, 4 and 5. First, the sheet material A is inserted between the feeding plate 8 and the pressing plate 9 as shown in FIG. 3, and first, the clamper 10 is driven in the direction of the arrow to press the feeding plate 8 against the pressing plate 9 to move the sheet material A. To pinch.

Next, as shown in FIG. 4A, when the rod 32a of the feed cylinder 32 extends and the pressing plate 9 is advanced into the cutting range a, the pressing plate 9 is pressed by the clamper 10.
The sheet material A also advances into the cutting range a together with the feed plate 8 which is pressed against. At this time, the feed plate 8 is urged by the spring 15 from the cutting blade 6 in the retreat range b direction (the arrow direction in the drawing). Therefore, as shown in FIG.
When the clamper 10 is released, the feed plate 8 retreats to the retreat range b, but at this moment, since the gripping piece 12 is raised to grasp the leading end of the sheet material A, the feed plate 8 strokes the surface of the sheet material A. The sheet material A can be held on the lower surface of the pressing plate 9 in a state where the sheet material A is taut. Thus, as shown in FIG. 4C, the pull-down plate cylinder 3
When the rod 31a of No. 1 is extended, the descending rod 19 descends, and when the pressing plate 9 is pressed against the cutting blade 6, the sheet material A is punched into the shape of the cutting blade 6.

The punched sheet material C is adhesively held in the cutting blade 6 as shown in FIG. 5 (a), and the pressing plate 9 is retracted by reducing the rod 32a. By this time, the adherend attachment means 2 has inserted the heated adherend B into the lower surface 4a of the fixed mold 4 with the surface on which the sheet material C is attached facing downward, and is supported by the protrusions 4b. Has been done. Then, when the rod 34a of the movable die cylinder 34 is extended, the movable die 5 passes through the inside of the cutting blade 6 and ascends while hooking the sheet material C, and the sheet is attached to the adherend B inserted into the fixed die 4. Material C is crimped.

[0020]

In the automatic cutting and bonding machine of the present invention, the two steps of cutting and bonding are integrated into one step, and the automation is greatly reduced, and the labor is greatly reduced, and the adhesive is held in the cutting blade after cutting. Since the sheet material can be immediately transferred to the pressure bonding step without being taken out from the cutting machine, when the sheet material is adhered using the heating device, the sheet materials can be attached to each other before they are cooled, and the thermal efficiency is good. When an adhesive application device is used instead of the heating device, it can be bonded immediately before it dries. In addition, since the process of peeling off the sheet material that has adhered to the cutting blade has become unnecessary, it is possible to use soft materials such as holes and nets that could not be peeled off from the cutting blade by means such as suction. I was able to do it. In addition, the positioning, which was very difficult to do during the crimping, has become easy. In other words, the sheet material is held in the cutting blade and the process proceeds to the pressure bonding step, so that the sheet material can be placed in a fixed position of the movable die, and the adherend held by the fixed die is easily deformed. Even if there is, it can be glued in place. Further, since the sheet material feeding / cutting device of the present invention feeds by sandwiching the entire area from both sides, it is possible to reliably feed any soft material to the cutting range, grasp the sheet front end with the grasping piece, and move the sheet surface. Since the feed plate is retracted to the retracted range in a leveled manner, the sheet can be cut in a taut state.
