The present invention will be described in detail below with reference to illustrated embodiments.
The lifter 2 is composed of a lift section 14 in which bars 12 are assembled in an X-shape at the center and their intersections are connected by a rotating shaft 13, a slide rail 15, and a mounting table 16. One end of the lift section 14 is connected to the slide rail. 1
5 and one end of the mounting table 16, respectively, and the other end of the lift section 14 is configured to slide. An elevating cylinder 17 is attached to the lift section 14 and is configured to move the lift section 14 up and down. The lifter 2 has a pit 1 dug deeper than the floor level 18 due to its height with the paper feeder 4.
It is located within 9. The mounting paper 1 is stacked on the mounting table 16 via a pallet 20. The mount 1 is a thick sheet-like material, and there are various types such as a porous material and a dense material without air permeability.The mount 1 is rectangular in shape, and its size and thickness vary depending on the type. The paper feeder 4 is disposed in front of the lifter 2, and has a paper feed arm 21 that reciprocates toward the lifter 2. A suction pad 22 is attached to the tip of the paper feed arm 21. Suction pad 2
A compression spring 24 is disposed on the pad 2 so that the pad portion 23 is sufficiently pressed against the mount 1 during suction. A pass line 8 conveys the mount 1, and a fixed roller 25 is disposed below the pass line 8. A first fixed roller 25a near the entrance 1a and a second
A guide plate 27 is provided between the fixed roller 25b and the fixed roller 25b.
is arranged, and is designed to be raised and lowered using the first fixed roller side as a fulcrum. First fixed roller 2
A lifting roller 28b that can be raised and lowered is disposed above the second fixed roller 25b on the inner side of 5a, and is linked to the raising and lowering of the guide plate 27. Above the third fixed roller 25c is a driving roller 28c. are arranged. Second and third fixed rollers 25b, 25
A detection device 31 consisting of a planar fluorescent lamp 29 and a light receiving element 30 disposed above the fluorescent lamp 29 is provided between the
are arranged. A gluing machine 3 is arranged in front of the paper feeder 4. There is a pair of upper and lower applicator rollers 32, and a doctor roller 33 is disposed on the side in contact with the applicator roller 32. The glue 5 is collected in the troughs 34 between the applicator roller 32 and the doctor roller 33, and is evenly distributed on the applicator roller 32. The glue 5 is applied to the surface of the mount 1 passing between the application rollers 32. 35 is a water washing tank, 36 is an injection nozzle, and 37 is a centrifugal pump. 38 is a ladder, pasting machine 3 in the previous process;
This is used to supply material to the lamination machine 7 in the next process. In the pasting machine 7, at the upper left end in the figure,
A roll 39 of the wound inner sole sheet 6 is installed, and a heater roller 40 is installed at the upper right end. The heater roller 40 is subjected to PID control, and is designed to always maintain a constant surface temperature between 120 and 70° C. depending on the type of the inner sole sheet 6. Of course, steam heating may also be used. A tension roller 41 is provided below the sheet roll 39 and the heater roller 40, and a tension roller 42 is provided at the lowest stage. In order to prevent the inner sole sheet 6 from wrinkling, a spiral groove 43, such as a helical gear, is formed on the outer circumferential surface of the heater roller 40 and the tension roller 41 so that force is always applied in the direction of spreading the inner sole sheet 6. It has been set up. The adhering roller 42 is attached to a pressing force adjusting arm 44 so that the inner sole sheet 6 can always be applied with a constant pressing force. In front of the laminating machine 7, a plurality of fixed rollers 25 are arranged below a pass line 8, and a pasting roller 9 is arranged above them. Like the sticking roller 42, the sticking roller 9 has a pressing force adjusting arm 44 to adjust the pressing force according to the type of the inner sole sheet 6.
is attached to. A dryer 10 is disposed in front of this group of sticking rollers 9. For the dryer 10, the most suitable heat source for drying is selected and used, such as hot air or a far-infrared heater. The thus dried composite pressboard 46 for the midsole is sent to the cutting machine 11, where a cutting cart 47 runs on a rail in accordance with the traveling speed of the composite pressboard 46 for the midsole. At the same time, the cutting blade 48 crosses over the composite pressboard 46 for the midsole to accurately cut the composite pressboard 46 for the midsole into a predetermined size.
There are two types of cutting signals: a magnetic sensor type and a phototube type. The former is used for non-transparent materials such as vinyl, and the latter is used for transparent materials such as cheesecloth. Then, the mount 1 is loaded on the lifter 2, and the paper feed arm 21 is driven.
When the paper feed arm 21 comes over the lifter 2, it descends, presses the pad portion 23 sufficiently against the mount 1, and attracts the mount 1. Next, the paper feed arm 21 rises, lifts up one mount 1 as shown by the chain double-dashed line in the figure, and moves to the paper feeder 4 side. At this time, a negative pressure may develop between the suctioned mount 1 and the mount 1 below it, which may result in a suction error, so an air supply hole 49 is provided at the end of the top mount 1 to feed air. Alternatively, a brush-like object 50 may be provided so that the end of the topmost mount 1 is easily lifted up. Further, the lifter 2 may be raised by one sheet each time the mount 1 is fed, or may be raised by detecting when several sheets are removed. When the mount 1 is supplied to the paper feeder 4, the detection device 31 detects this, the lifting roller 28b descends, the mount 1 is held between the lifting roller 28b and the second fixed roller 25b, and rotated to apply the glue. Transfer to machine 3. At this time, the guide plate 27 has collapsed into a horizontal state. The gluing machine 3 uniformly glues the mount 1 as described above. When the mount 1 is conveyed while being held between the drive roller 28c and the third fixed roller 25c, the elevating roller 28b rises and at the same time the guide plate 27 rises. At this time, the free end of the guide plate 27 will be located slightly below the lifting roller 28b. Subsequently, the next mount 1 is fed, but the previous mount 1 is sent to the next process, and the mount 1 falls below the guide plate 27. On the other hand, the leading edge of the newly supplied mount 1 is placed on the guide plate 27, so that the two do not overlap each other. This is because in the next operation, the paper feed arm 21 reciprocates to feed the next mount 1, but the paper feed state is not constant.
The tip position of the supplied mount 1 varies and may overlap with the previous mount 1, but this is to prevent this. Now, when a gap is created between the previous mount 1 and the newly supplied mount 1 and the light receiving element 30 detects fluorescence, the lifting roller 28b
At the same time as the guide plate 27 descends, the guide plate 27 falls down horizontally, and as described above, the guide plate 27 is supplied with a constant interval between the front and back of the mount 1. This is for the convenience of the final cutting process. When the front end of the newly supplied mount 1 comes to be caught between the drive roller 28c and the third fixed roller 25C, the elevating roller 28b rises, and the guide plate 27 also rises accordingly. After that, the next mount 1
is supplied by the action of the paper feed arm 21, and the above-described operation is repeated. Note that the first to third fixed rollers 25
a, 25b, and 25c rotate synchronously. The mount 1 that has been evenly pasted in the pasting machine 3 in the next step is sent to the pasting machine 7, where the inner sole sheet 6
is pasted on the surface, but the effect of the spiral grooves 43 prevents wrinkles from forming. Next, the adhesion roller 9 applies an optimal pressing force to the sheet 6 for the insole by the action of the pressing force adjustment arm 44, thereby increasing the adhesion force and forming the composite press board 46 for the insole. In this way, the sheet 6 for the inner sole is evenly adhered to the mount 1 to form the composite pressboard 46 for the inner sole, and then the board is sent to the dryer 10. The dryer 10 heats and dries the composite press board 46 for shoe insoles using hot air, far infrared rays, and other heat sources. After sufficient drying, the composite press board 46 for shoe insoles is cut by the cutting machine 11.
and cut into predetermined dimensions using the method described above.

2 and 3 show another embodiment of the paper feed arm 21 of the present invention, in which a slide block 52 is attached to a guide shaft 51 and is driven back and forth by a drive cylinder (not shown). It is. A leaf spring 53 is attached to the slide block 52 so as to be inclined downwardly toward the lifter 2 side, and the air cylinder 54
The needle 55 at the tip is raised and lowered by driving the paper feeder 4.
When drawing the mount 1 to the side, the plate spring 53 is bent and a needle 55 is inserted into the mount 1 to pull it closer, and it is used when the mount 1 is porous (because it cannot be attracted). The installation angle θ of the needle 55 is 45 to 60 degrees with respect to the mount 1, and the installation angle θ is 45 to 60 degrees with respect to the mount 1.
It is now fixed at .

As described above, in the present invention, a drive roller for paper feeding is disposed above the third fixed roller, and the backing paper is fed to the gluing machine through cooperation between the drive roller and the third fixed roller. When the detection device detects the rear end, it descends, rotates and transports the front end of the next mount between the second fixed roller, and in cooperation with the second fixed roller, the mount being transported is moved between the drive roller and the third fixed roller. An elevating roller that is engaged with the roller and rises when the detection device is cut off is disposed above the second fixed roller, and falls horizontally below the pass line when the elevating roller descends;
A guide plate is provided between the first and second fixed rollers that rises diagonally toward the lifting rollers with the first fixed roller side as a fulcrum when the lifting rollers rise. The rear end enters below the guide plate, and the front end of the backing paper rests on the guide plate so that the two do not overlap, allowing smooth supply of the backing paper, and furthermore, between the second and third fixed rollers. is equipped with a detection device that detects the gap between the backing sheets being supplied, so it is possible to create the required gap between the backing sheets between the second and third fixed rollers, and cut the inner bottom sheet in this gap. This has the advantage that the final cutting process can be carried out smoothly.
