Summary of the Invention

Problems to be Solved by the Invention

[0004] When a lower cylinder is disposed below the lower die, the pressing position on the press object by the upper die and the lower die becomes higher. When the pressing position becomes higher, the workability of the operator deteriorates. Even if a measure is taken to lift the entire floor to increase the working height of the operator, it is not preferable because it causes an increase in the overall cost.

Means for Solving the Problems

[0005] The press machine of the present disclosure is a press machine that heats and presses an object to be pressed conveyed in a first direction, and includes a first type having a first heater, a second type having a second heater and disposed above the first type, a support member that supports the first type and the second type, and a moving mechanism that moves the support member from a first position to a second position in a second direction intersecting the first direction with respect to the first position. The first position is a position where the first type and the second type heat and press the object to be pressed, and the second position is a position where the first type and the second type do not face the object to be pressed.

Embodiments for Carrying Out the Invention

[0007] FIG. 1 shows a schematic configuration of a press machine 10. The press machine 10 is a device that heats and presses a material M drawn out from a supply roller 12. The material M heated and pressed by the press machine 10 is wound around a take-up roller 14. The press machine 10 includes a lower die 20, a lower die heater 22, an upper die 30, an upper die heater 32, an air cylinder 35 for the upper die, a hanger spring 38, and a base 40.

[0008] Each figure including Figure 1 shows an XYZ coordinate system. The X-axis, Y-axis, and Z-axis are perpendicular to each other. The X-axis is parallel to the installation surface of the press 10 and corresponds to the width of the press 10. The Y-axis is parallel to the installation surface of the press 10 and corresponds to the depth of the press 10. The Z-axis is perpendicular to the installation surface of the press 10 and corresponds to the height of the press 10.

[0009] Hereinafter, when showing the XYZ coordinate system, the +X direction parallel to the X-axis indicates the direction in which the material M moves from the supply roller 12 to the take-up roller 14. In the case of Figure 1, the +X direction indicates the direction from the center of the figure to the right. The -X direction parallel to the X-axis indicates the direction from the take-up roller 14 to the supply roller 12. In the case of Figure 1, the -X direction of the X-axis indicates the direction from the center of the figure to the left. The +Y direction parallel to the Y-axis indicates the direction from the back to the front of the press 10 when the supply roller 12 is arranged on the left with respect to the base 40. In the case of Figure 1, the +Y direction parallel to the Y-axis indicates the direction towards the front of the figure. The -Y direction parallel to the Y-axis indicates the direction from the front to the back of the press 10 when the supply roller 12 is arranged on the left with respect to the base 40. In the case of Figure 1, the -Y direction parallel to the Y-axis indicates the direction towards the back of the figure. The +Z direction parallel to the Z-axis indicates the direction upward from the installation surface of the press 10. In the case of Figure 1, the +Z direction parallel to the Z-axis indicates the direction from the center of the figure upward. The -Z direction parallel to the Z-axis indicates the direction from above the press 10 towards the installation surface. In the case of Figure 1, the -Z direction parallel to the Z-axis indicates the direction from the center of the figure downward. The -Z direction corresponds to the vertical direction. The +X direction corresponds to an example of the first direction.

[0010] The lower die 20 is arranged at the -Z direction position of the material M drawn out from the supply roller 12. The lower die 20 contacts the material M at the lower die pressing surface facing the material M. The lower die pressing surface is rectangular. The lower die 20 heats the material M in contact with the lower die pressing surface. The lower die 20 corresponds to an example of the first die.

[0011] The lower mold heater 22 heats the lower mold 20. The lower mold heater 22 may be a resistance heating device or an induction heating device. The lower mold heater 22 may be disposed on a surface different from the lower mold pressing surface of the lower mold 20, or may be disposed inside the lower mold 20. The heating temperature of the lower mold heater 22 is controlled by a controller (not shown). The lower mold heater 22 corresponds to an example of the first heater.

[0012] The upper mold 30 is disposed at the +Z direction position of the lower mold 20 and the material M drawn out from the supply roller 12. The upper mold 30 is disposed above the lower mold 20 and faces the lower mold 20. The upper mold 30 contacts the material M with the upper mold pressing surface facing the lower mold pressing surface of the lower mold 20. The upper mold pressing surface has a rectangular shape. The upper mold 30 and the lower mold 20 sandwich the material M and heat and press the material M. The upper mold 30 corresponds to an example of the second mold.

[0013] The upper mold heater 32 heats the upper mold 30. The upper mold heater 32 may be a resistance heating device or an induction heating device. The upper mold heater 32 may be disposed on a surface different from the upper mold pressing surface of the upper mold 30, or may be disposed inside the upper mold 30. The heating temperature of the upper mold heater 32 is controlled by a controller (not shown). The upper mold heater 32 corresponds to an example of the second heater.

[0014] The air cylinder 35 for the upper mold is disposed on a base 40 described later. The air cylinder 35 for the upper mold has an air cylinder rod 36 for the upper mold. The air cylinder 35 for the upper mold is an actuator that linearly moves the air cylinder rod 36 for the upper mold using compressed air. The air cylinder rod 36 for the upper mold supports the upper mold 30. The air cylinder 35 for the upper mold moves the upper mold 30 supported by the air cylinder rod 36 for the upper mold in the -Z direction. When compressed air is introduced into the air cylinder 35 for the upper mold, the air cylinder rod 36 for the upper mold moves the upper mold 30 in the -Z direction.

[0015] When the upper mold air cylinder 35 moves the upper mold 30 in the -Z direction, the upper mold 30 and the lower mold 20 sandwich the material M and heat and press the material M. After the upper mold 30 and the lower mold 20 heat and press the material M, the compressed air in the upper mold air cylinder 35 is discharged. When the compressed air is discharged from the upper mold air cylinder 35, the upper mold 30 moves in the +Z direction. By the upper mold 30 moving in the +Z direction, the upper mold 30 becomes non-contact with the material M.

[0016] The suspension spring 38 is arranged on a base 40 described later. The suspension spring 38 is connected to the upper mold 30 and supports the upper mold 30. When the compressed air in the upper mold air cylinder 35 is discharged, the suspension spring 38 moves the upper mold 30 in the +Z direction by elastic force. When compressed air is introduced into the upper mold air cylinder 35, the upper mold air cylinder rod 36 moves the upper mold 30 in the -Z direction against the elastic force of the suspension spring 38. The press 10 shown in FIG. 1 is provided with two suspension springs 38, but is not limited thereto. The suspension spring 38 may be one, or three or more. The suspension spring 38 may have any configuration as long as it can support the upper mold 30.

[0017] The base 40 supports the lower mold 20 and the upper mold 30. The base 40 supports the upper mold 30 via the upper mold air cylinder rod 36 and the suspension spring 38. The base 40 is moved by a slide mechanism 70 described later. The base 40 corresponds to an example of a support member.

[0018] The material M is molded by the press 10. The material M is, for example, a fiber material molded into a sound-absorbing material that absorbs sound, a cushioning material that absorbs external impacts, an ink absorber that absorbs ink, etc. The fiber material is a fibrous web formed by depositing a defibrated product obtained by defibrating a fiber raw material containing fibers and a molten material. The material M corresponds to an example of an object to be pressed.

[0019] First Embodiment Figure 2 shows a schematic configuration of the press 10 in which the base 40 is in the operating position. Figure 3 shows a schematic configuration of the press 10 in which the base 40 is in the retracted position. Figures 2 and 3 are views of the press 10 seen from the +X direction. Figures 2 and 3 show the configuration of the press 10 of the first embodiment. The operating position is a position where the lower die 20 and the upper die 30 supported by the base 40 face the material M. In the operating position, the lower die 20 and the upper die 30 can heat and pressurize the material M. The operating position corresponds to an example of the first position. The retracted position is a position where the lower die 20 and the upper die 30 supported by the base 40 do not face the material M. When the base 40 moves to the retracted position, it becomes difficult for the material M to receive radiant heat from the lower die 20 and radiant heat from the upper die 30. The retracted position corresponds to an example of the second position.

[0020] Figures 2 and 3 show the lower die 20, the upper die 30, the air cylinder 35 for the upper die, the air cylinder rod 36 for the upper die, the base 40, and the material M. Also, Figures 2 and 3 show the lower frame 60, the slide mechanism 70, and the first side frame 100. Figures 2 and 3 show the air cylinder 71 for the base and the spring 73 for the base included in the slide mechanism 70. Figures 2 and 3 omit the lower die heater 22, the upper die heater 32, and the hanger spring 38. As long as the air cylinder 35 for the upper die has a configuration that enables pressing, for example, a hydraulic cylinder, a mechanical drive mechanism, a motor, etc. may be used. In this case, a configuration having a separate mechanism for temporarily releasing a brake or the like during movement upward to the avoidance position by a spring is also possible.

[0021] The lower frame 60 supports the base 40 and the air cylinder 71 for the base. The lower frame 60 supports the base 40 so as to be movable along an axis parallel to the Y-axis. A mounting surface 60S for mounting the base 40 of the lower frame 60 may be provided with a guide member for guiding the base 40 (not shown).

[0022] The slide mechanism 70 has a base air cylinder 71 and a base spring 73. The slide mechanism 70 is provided at a position in a direction intersecting the direction in which the material M is conveyed, and at a position different from below the lower mold 20 located at the operating position. In FIGS. 2 and 3, the slide mechanism 70 is provided at a position in the -Y direction. The slide mechanism 70 uses the base air cylinder 71 and the base spring 73 to move the base 40 in the -Y direction and the +Y direction. When the slide mechanism 70 moves the base 40 in the -Y direction, the base 40 is located at the retracted position. When the slide mechanism 70 moves the base 40 in the +Y direction, the base 40 is located at the operating position. The slide mechanism 70 corresponds to an example of a moving mechanism. The -Y direction is a direction orthogonal to the -Z direction and corresponds to an example of a second direction. The +Y direction corresponds to an example of a direction opposite to the second direction.

[0023] The base air cylinder 71 is disposed on the lower frame 60. The base air cylinder 71 has a base air cylinder rod 72. The base air cylinder 71 is an actuator that linearly moves the base air cylinder rod 72 using compressed air. The base air cylinder rod 72 is connected to the base 40. The base air cylinder 71 moves the base 40 connected to the base air cylinder rod 72 in the +Y direction. When compressed air is introduced into the base air cylinder 71, the base air cylinder rod 72 moves the base 40 in the +Y direction. By introducing compressed air into the base air cylinder 71, the base 40 moves from the retracted position to the operating position. The base air cylinder 71 corresponds to an example of a moving member. The member that moves the base 40 from the retracted position to the operating position is not limited to an air cylinder. As long as it is a configuration for moving the base 40, for example, a hydraulic cylinder, a mechanical drive mechanism, a motor, etc. may be used.

[0024] The base spring 73 is connected to the base 40 and the first side frame 100. When the compressed air contained in the base air cylinder 71 escapes, the base spring 73 moves the base 40 in the -Y direction by its elastic force. When compressed air is introduced into the base air cylinder 71, the base air cylinder rod 72 moves the base 40 in the +Y direction against the elastic force of the base spring 73. The press 10 shown in FIGS. 2 and 3 includes one base spring 73, but is not limited thereto. Two or more base springs 73 may be provided. A member other than the base spring 73 may be used as a configuration for moving the base 40 in the -Y direction. The member other than the base spring 73 may be any configuration that can apply a force to move the base 40 in the -Y direction. The base spring 73 corresponds to an example of an elastic member.

[0025] As shown in FIGS. 2 and 3, the base 40 that supports the lower die 20 and the upper die 30 moves to the operating position and the retracted position. The base spring 73 applies an elastic force that moves the base 40 in the -Y direction. The elastic force that moves the base 40 in the -Y direction corresponds to an example of the force for moving in the second direction. The base air cylinder 71 moves the base 40 in the +Y direction.

[0026] As shown in FIG. 2, when the base 40 is located at the operating position, the lower die 20 and the upper die 30 face the material M. When the base 40 is located at the operating position, the upper die air cylinder 35 moves the upper die 30 in the -Z direction, so that the lower die 20 and the upper die 30 heat and press the material M. The lower die 20 and the upper die 30 mold the material M by heat and pressure.

[0027] As shown in FIG. 3, when the base 40 is in the retracted position, the lower mold 20 and the upper mold 30 do not face the material M. The lower mold 20 is located at a position different from the -Z direction position of the material M. The upper mold 30 is located at a position different from the +Z direction position of the material M. By positioning the lower mold 20 and the upper mold 30 at positions where they do not face the material M, it becomes difficult for the radiant heat from the lower mold 20 and the upper mold 30 to affect the material M. For example, when the press 10 is stopped, by moving the base 40 to the retracted position, the heat transmitted to the material M during the stop of the press 10 is reduced. When the material M is a material that is easily deteriorated by heat, the deterioration of the material M when the press 10 is stopped is reduced. Also, by positioning the base 40 at the retracted position, the lower mold heater 22 and the upper mold heater 32 can maintain heating during the stop. The press 10 can resume molding in a short time when it moves from the standby position to the operating position.

[0028] As shown in the first embodiment, the slide mechanism 70 moves the base 40 in the -Y direction. The slide mechanism 70 includes a base spring 73 that applies an elastic force to move the base 40 in the -Y direction and a base air cylinder 71 that moves the base 40 in the +Y direction to the base 40. The press 10 does not need to provide the slide mechanism 70 below the operating position by moving the base 40 in the -Y direction.

[0029] Second Embodiment FIG. 4 shows a schematic configuration of the press machine 10 in which the base 40 is in the operating position. FIG. 5 shows a schematic configuration of the press machine 10 in which the base 40 is in the retracted position. FIGS. 4 and 5 are views of the press machine 10 as seen from the +X direction. FIGS. 4 and 5 show the configuration of the press machine 10 of the second embodiment. The operating position is a position where the lower die 20 and the upper die 30 supported by the base 40 face the material M. In the operating position, the lower die 20 and the upper die 30 can heat and pressurize the material M. The operating position corresponds to an example of the first position. The retracted position is a position where the lower die 20 and the upper die 30 supported by the base 40 do not face the material M. When the base 40 moves to the retracted position, it becomes difficult for the material M to receive radiant heat from the lower die 20 and radiant heat from the upper die 30. The retracted position corresponds to an example of the second position.

[0030] FIGS. 4 and 5 show the lower die 20, the upper die 30, the air cylinder 35 for the upper die, the air cylinder rod 36 for the upper die, the base 40, and the material M. FIGS. 4 and 5 also show the lower frame 60 and the slide mechanism 70. FIGS. 4 and 5 show the air cylinder 71 for the base included in the slide mechanism 70. FIGS. 4 and 5 omit the lower die heater 22, the upper die heater 32, and the hanger spring 38.

[0031] The press machine 10 of the second embodiment does not have the base spring 73 shown in FIGS. 2 and 3. In the second embodiment, the mounting surface 60S of the lower frame 60 is inclined. The inclined mounting surface 60S corresponds to an example of an inclined surface.

[0032] The lower frame 60 of the second embodiment supports the base 40. The air cylinder 71 for the base may be supported by the lower frame 60 or may be supported by a frame (not shown) or the like. The lower frame 60 has a mounting surface 60S on which the base 40 is mounted. The mounting surface 60S is inclined in the -Z direction toward the -Y direction. The base 40 can move obliquely downward on the mounting surface 60S from the operating position toward the retracted position. A guide member for guiding the base 40 (not shown) may be provided on the mounting surface 60S.

[0033] The slide mechanism 70 has a base air cylinder 71. The slide mechanism 70 is provided at a position in a direction intersecting the direction in which the material M is conveyed, at a position different from below the lower mold 20 located at the operating position. In FIGS. 4 and 5, the slide mechanism 70 is provided at a position in the -Y direction. The slide mechanism 70 uses the base air cylinder 71 to move the base 40 obliquely downward in the -Y direction and obliquely upward in the +Y direction. When the slide mechanism 70 moves the base 40 obliquely downward, the base 40 is located at the retracted position. When the slide mechanism 70 moves the base 40 obliquely upward, the base 40 is located at the operating position. The slide mechanism 70 corresponds to an example of a moving mechanism. Obliquely downward in the -Y direction corresponds to an example of a second direction. Obliquely upward in the +Y direction corresponds to an example of a direction opposite to the second direction.

[0034] The base air cylinder 71 has a base air cylinder rod 72. The base air cylinder 71 is an actuator that linearly moves the base air cylinder rod 72 using compressed air. The base air cylinder rod 72 is connected to the base 40.

[0035] As shown in FIG. 5, in a state where no compressed air is introduced into the base air cylinder 71, the base 40 is located at the retracted position. When compressed air is introduced into the base air cylinder 71, the base air cylinder rod 72 moves the base 40 obliquely upward in the +Y direction. By introducing compressed air into the base air cylinder 71, the base 40 moves from the retracted position to the operating position. In a state where compressed air is introduced into the base air cylinder 71, the base 40 is located at the operating position as shown in FIG. 4.

[0036] When the compressed air contained in the air cylinder 71 for the base is released, the pressing force applied to the base 40 by the air cylinder rod 72 for the base decreases. When the pressing force decreases, the base 40 moves obliquely downward in the -Y direction along the inclination of the placement surface 60S due to its own weight. The base 40 moves obliquely downward in the -Y direction and obliquely upward in the +Y direction by the pressing force applied to the base 40 by the air cylinder 71 for the base. The air cylinder 71 for the base corresponds to an example of a moving member.

[0037] When the slide mechanism 70 moves the base 40 obliquely downward, the own weight of the base 40 can be used. Since the air cylinder 71 for the base is configured to release compressed air when the power is turned off, in the event of an emergency such as a power failure, the base 40 moves from the operating position to the retracted position. When the power of the press 10 is turned off, the possibility that the material M receives excessive heating is reduced.

[0038] As shown in the second embodiment, the direction in which the base 40 moves is the direction toward obliquely downward of the material M. The base 40 is placed on the placement surface 60S that is inclined obliquely downward in the -Y direction. The slide mechanism 70 has an air cylinder 71 for the base that moves obliquely downward in the -Y direction and obliquely upward in the +Y direction. By moving the base 40 obliquely downward, the slide mechanism 70 can use the own weight of the base 40 including the lower die 20 and the upper die 30 for the movement of the base 40.

[0039] Third Embodiment FIG. 6 shows a schematic configuration of the press machine 10 in which the base 40 is in the operating position. FIG. 7 shows a schematic configuration of the press machine 10 in which the base 40 is in the retracted position. FIGS. 6 and 7 are views of the press machine 10 as seen from the +X direction. FIGS. 6 and 7 show the configuration of the press machine 10 of the third embodiment. The operating position is a position where the lower die 20 and the upper die 30 supported by the base 40 face the material M. In the operating position, the lower die 20 and the upper die 30 can heat and pressurize the material M. The operating position corresponds to an example of the first position. The retracted position is a position where the lower die 20 and the upper die 30 supported by the base 40 do not face the material M. When the base 40 moves to the retracted position, it becomes difficult for the material M to receive radiant heat from the lower die 20 and radiant heat from the upper die 30. The retracted position corresponds to an example of the second position.

[0040] FIGS. 6 and 7 show the lower die 20, the upper die 30, the air cylinder 35 for the upper die, the air cylinder rod 36 for the upper die, the base 40, and the material M. FIGS. 6 and 7 also show the lower frame 60 and the slide mechanism 70 including the air cylinder 71 for the base, the winding spring 80, and the second side frame 110. FIGS. 6 and 7 omit the lower die heater 22, the upper die heater 32, and the hanging spring 38.

[0041] The press machine 10 of the third embodiment has a winding spring 80. The press machine 10 of the third embodiment has the same structure as the press machine 10 of the second embodiment except for the air cylinder 71 for the base and the winding spring 80.

[0042] The air cylinder 71 for the base of the third embodiment is supported at a position in the -Y direction of the mounting surface 60S of the lower frame 60. The air cylinder 71 for the base is arranged along the inclination of the mounting surface 60S. The air cylinder rod 72 for the base linearly moves along the inclination of the mounting surface 60S. The air cylinder 71 for the base can apply a pressing force along the moving direction of the base 40.

[0043] The second side frame 110 is disposed at the +Y direction position of the lower frame 60. The second side frame 110 may be integrally formed with the lower frame 60. The second side frame 110 supports the winding spring 80.

[0044] The winding spring 80 is disposed in the +Y direction of the lower die 20. The winding spring 80 has a spring member 80A. The spring member 80A is, for example, a leaf spring. The spring member 80A may also be a wire. The spring member 80A has elasticity. One end of the spring member 80A is connected to the lower die 20. The lower die 20 is connected to the spring member 80A at the upper end in the +Y direction.

[0045] As shown in FIG. 6, when the base 40 is in the operating position, the winding spring 80 winds the spring member 80A to a predetermined length. The winding spring 80 winds the spring member 80A by the elastic force of the spring member 80A itself. The winding spring 80 applies tension and pulls the lower die 20 in the +Y direction. The winding spring 80 applies a tensile force that assists the pressing force applied by the base air cylinder 71 when the base 40 is in the operating position.

[0046] FIG. 7 shows the state when the base 40 moves from the operating position to the retracted position at an unexpected timing. When the press 10 receives an instruction to move the base 40 to the retracted position while heating and pressing the material M, the press 10 moves the base 40 from the operating position to the retracted position. The strength of the material M may decrease during heating and pressing depending on its material. As shown in FIG. 7, the material M may deform due to its own weight as its strength decreases. The spring member 80A is in a state where tension is applied by the movement of the base 40. The spring member 80A extends below the material M. When the base 40 moves from the operating position to the retracted position, the spring member 80A can support the deformed material M. The winding spring 80 corresponds to an example of a support mechanism.

[0047] When the base 40 moves from the retracted position to the operating position, the spring member 80A supports the deformed material M. When the base 40 moves from the retracted position to the operating position, the spring member 80A can reduce the possibility that the deformed material M contacts the lower mold 20. When the base 40 moves from the retracted position to the operating position, the possibility of the material M being damaged is reduced.

[0048] When the base 40 moves from the retracted position to the operating position, the spring member 80A is tensioned. The winding spring 80 applies a pulling force obliquely upward in the +Y direction during the movement of the base 40. The winding spring 80 can assist the base air cylinder 71 when moving the base 40.

[0049] As shown in the third embodiment, the press 10 has a winding spring 80 as a support mechanism capable of supporting the material M when the base 40 moves in the -Y direction. The material M may bend by heating and pressurization. When the base 40 of the press 10 moves in the -Y direction, the winding spring 80 supports the material M, so the possibility of contact between the lower mold 20 and the material M can be reduced. Although the form using the winding spring 80 as a preferred example of the support mechanism has been described, any mechanism having a similar function can be applied to the present invention.

[0050] As described above, the press 10 heats and pressurizes the material M conveyed in the +X direction. The press 10 includes a lower mold 20 having a lower mold heater 22, an upper mold 30 having an upper mold heater 32 and disposed above the lower mold 20, a base 40 supporting the lower mold 20 and the upper mold 30, and a slide mechanism 70 that moves the base 40 from the operating position to a retracted position in the -Y direction intersecting the +X direction with respect to the operating position. The operating position is a position where the lower mold 20 and the upper mold 30 heat and pressurize the material M. The retracted position is a position where the lower mold 20 and the upper mold 30 do not face the material M. By moving the base 40 that supports the lower mold 20 and the upper mold 30 to the retracted position in the -Y direction, the press 10 does not need to provide a moving mechanism below the lower mold 20 located at the operating position. Since the press 10 does not need to raise the press position to provide a moving mechanism, the workability of the operator is not reduced.
