From the state where the step portion 35 is formed together with the lower plate 32 by the cylinder 38, the cylinder 38 is reciprocated in the range of the base end side (upper side) of the molding drum 4.
[0032]
Further, the mechanism for holding one end of the long work W is a work holding needle 39 projecting and retracting with respect to the outer peripheral surface 36B of the end of the movable clamp 36 (only one is shown in the illustrated example, but two When the workpiece holding needle is used, the rotation of the long workpiece W around the holding needle can be suppressed and the long workpiece W can be held more accurately), and a needle driving cylinder that drives the workpiece holding needle 39 to project and retract. 40. At this time, the workpiece holding needle 39 rotates together with the movable clamp 36, and the needle driving cylinder 40 is fixed to the lower plate 32. Therefore, the workpiece holding needle 39 and the needle driving cylinder 40 are connected by a rotating arm 41 that follows the change in position of both.
[0033]
The structure holding means 5 includes a holding plate 42, a plate raising / lowering cylinder 43 for raising and lowering the holding plate 42, and a plurality of guide rods 44 for guiding the raising / lowering operation thereof. As shown in FIG. 8, the structure C has screw through holes H at three locations on the outer peripheral side.

[0034]
In addition, a positioning plate 49 having a plurality of locating pins 48 provided upright is provided below the holding plate 42. When the holding plate 42 reaches the lowering limit, the locating pin 48 is moved to the holding plate 42 and the centering jig. By passing through 46, the structure C placed on the holding plate 42 can be positioned accurately.
[0035]
Further, as shown in FIG. 1, the affixing device 1 includes a drum guide 50 for guiding the horizontally moving molding drum 4 to the gantry 2 (when the molding drum 4 moves horizontally, the pinion 26 and It is not always necessary if the meshed state with the rack 21 is maintained), and a chute 51 for discharging the release paper 6 after all the long workpieces W have been peeled off. Each movable part is provided with various sensors for detecting these movements and movement limits.
[0036]
The long workpiece W sticking device 1 having the above-described configuration sets a plurality of sheets S on the sheet magazine 7 from one side of the device and sets the structure C on the structure holding means 5 from the front of the device. After setting, start the operation by operating the start button.
[0037]
First, the lowermost sheet S in the sheet magazine 7 is sent to the molding drum 4 side by the workpiece supply means 3, and the sheet S is loaded at a position where the long workpiece W at the front end corresponds to the step portion 35 of the molding drum 4. Stop. Further, the molding drum 4 moves from a position D2 on the front side of the apparatus shown in FIG. 3 to a position D1 on the rear side of the apparatus, and then lowers to a position where the lower end reaches the conveyor 8. At this time, as shown in FIG. 10A, in the forming drum 4, the stepped portion of the movable clamp 36 is engaged with one end portion of the long workpiece W at the front end of the sheet S. The workpiece holding needle 39 is in a rotational position facing the side surface.
[0038]
Next, the sticking device 1 projects the work holding needle 39 from the stepped outer peripheral surface 36B of the movable clamp 36 and pierces the long work W, and then, as shown in FIG. Rotate upward. As a result, the long workpiece W at the front end of the sheet S is peeled off from the release paper 6 satisfactorily as shown in FIG. Then, the long work W is wound around the step portion 35 of the forming drum 4 by horizontally moving the forming drum 4 counterclockwise in FIG.
[0039]
At this time, in the attaching apparatus 1, the linear long work W is peeled along the surface of the release paper 6. First, one end of the long work W is rotated with the rotation of the movable clamp 36. Since the part is peeled upward, the subsequent peeling is performed well. Further, since the work holding needle 39 is used, there is no fear of causing damage to the long work W, and when the long work W is made of sponge as in this embodiment, There is no damage caused by the workpiece holding needle 39.
[0040]
Further, in the winding process, the forming drum 4 is rotated and moved horizontally to take up the long work W, so that one end of the long work W is reliably secured by a simple structure using the work holding needle 39. In addition to being held, the tensile force in the longitudinal direction with respect to the long workpiece W becomes small, and even the long workpiece W that is easily cut can be reliably wound, and the step of the step portion 35 of the molding drum 4 is also possible. Since the part outer peripheral surface 35B is tapered, the long workpiece W is wound up without being detached from the stepped part 35.
[0041]
When the long work W is wound around the forming drum 4 as described above, the long work W has a dimension longer than the circumference of the forming drum 4 as described above, and therefore, as shown in FIG. In addition, the other end portion enters the lower side of the one end portion that has moved upward together with the movable clamp 36. In this state, the lower surface of the long workpiece W is an adhesive surface.
[0042]
Therefore, the affixing device 1 temporarily stops the horizontal movement of the forming drum 4 in a state where the other end of the long workpiece W remains on the release paper 6 and rotates the movable clamp 36 downward. Thus, as shown in FIG. 10 (d), the bonding surface of one end is bonded to the upper surface of the other end, and the long workpiece W is continuously annularly formed. When the end portions are overlapped in this way, it is more desirable to cut the other end portion of the long workpiece W obliquely as shown in FIG.
[0043]
Thereafter, the affixing device 1 moves the molding drum 4 to a position D2 corresponding to the structure holding means 5. At this time, the long workpiece W is continuous in an annular shape, and the step portion outer peripheral surface 35B of the step portion 35 is tapered, so that it does not fall off from the forming drum 4. Then, the positional relationship between the forming drum 4 and the structure holding means 5 is made coaxial, and after the work holding needle 39 is removed from the long work W, the structure C is raised by the structure holding means 5. 8 and FIG. 9, the long workpiece W is attached to the structure C. At this time, in the attaching device 1, the long work W is pressed against the structure holding means 5 side by the step end surface 35 </ b> A of the step 35 in the forming drum 4, and the long work W is pressed against the structure C. Adhere more securely.
[0044]
After that, the affixing device 1 raises the molding drum 4 and lowers the structure C by the structure holding means 5 so that the structure C can be taken out. Is rotated by an amount corresponding to the width of the long workpiece W, the sheet S is advanced so that the next long workpiece W corresponds to the forming drum 4, and a new structure C is transferred to the structure holding means 5. After setting, the above operation is repeated. When the pasting of all the long workpieces W on the sheet S is completed, the conveyor 8 is driven to rotate, the release paper 6 is discharged from the chute 51, and the next sheet S is removed from the sheet magazine 7 by the extruding member 16. To the forming drum 4 side.
[0045]
In this way, the above-described long work W sticking apparatus 1 automatically supplies the long work W from the work supplying means 3 and only winds the long work W around the forming drum 4 that moves while rotating. Thus, the long work W can be bent very easily and quickly into a predetermined ring shape, and the long work W can be automatically attached to the structure C. Further, the pasting apparatus 1 is greatly reduced in size as compared with the conventional apparatus using a robot, and the labor relating to the reduction of the equipment cost and the maintenance and management of the equipment becomes easy.
[0046]
In the above embodiment, the surface on which the long workpiece W is wound is tapered, and the long workpiece W is prevented from falling off. Instead, the surface to be wound is a simple cylindrical surface, Further, a plurality of holding needles protrude from the cylindrical surface to prevent the long work W from falling off with each holding needle, and when attaching to the structure, the holding needle is moved backward to You may make it move away to the structure side smoothly.
[0047]
In the above embodiment, the case where the long workpiece W is bent in an annular shape has been described, but the bending shape of the workpiece W can be various shapes as long as there is no dent toward the center side, In the forming drum corresponding to this, when moving linearly, the one end part of the long workpiece W may be held at a position farthest from the center. Furthermore, when the bending shape of the long work W is other than an annular shape, the forming drum is moved along a curve corresponding to the bending shape, and the forming drum is moved along the long work W supplied in a straight state. Can also be rolled. Furthermore, in the above-described embodiment, the metal structure C and the sponge-like long workpiece W are exemplified. However, as a matter of course, these materials are not limited to the above-described embodiment.
