Description
Technical Field
The present invention relates to a lamp unit including at least one lamp, and also relates to a heating device including the lamp unit.
Background
Conventionally, a lamp unit including a lamp and a terminal plate connected to the lamp is known as a lamp unit (for example, patent document 1). Further, the lamp is provided with: a pipe body having sealing parts at both ends; a metal foil embedded in the sealing part; and a lead bar, an inner end portion of the lead bar being fixed to the metal foil and an outer end portion of the lead bar being fixed to the terminal plate. The terminal plate is fixed to the device to attach the lamp unit to the device.
However, when manufacturing errors occur in the shape of the tube body or the position at which the terminal plate is fixed to the lead bar, for example, in manufacturing the lamp unit, manufacturing errors also occur in the positional relationship between the terminal plates. In such a case, when the terminal plate is fixed to the device, stress acts on the metal foil via the lead bar. Therefore, when the seal portion cannot receive such stress, the seal portion may be broken.

Detailed Description
Hereinafter, an embodiment of the lamp unit and the heating device will be described with reference to fig. 1 to 6. In each drawing (the same also applies to fig. 7 to 9), the dimensional ratio in the drawing does not necessarily coincide with the actual dimensional ratio, and the dimensional ratios in the drawings do not necessarily coincide with each other.
As shown in fig. 1, the heating device 1 of the present embodiment is provided in an image forming apparatus 10 such as a copying machine, and is used as a fixing device of the image forming apparatus 10. The heating device 1 further includes: a lamp unit 2; a cylindrical heating roller 1a in which the lamp unit 2 is housed; and a pressure roller 1b that conveys the paper 101 between the pressure roller 1b and the heating roller 1 a.
In the image forming apparatus 10, the heat roller 1a is heated by the heat generated by the lamp unit 2. Then, the paper 101 is fed between the heating roller 1a and the pressure roller 1b, and the toner 102 applied to the paper 101 is heated and melted. Thereby, an image (characters, patterns, or the like) is formed by the toner 102 fixed to the paper 101.
As shown in fig. 1 and 2, the lamp unit 2 includes a plurality of (two in the present embodiment) lamps 3 and terminal plates 21 to 23 fixed to the lamps 3. The first terminal plate 21 is fixed to the first end portions 3a, 3a of the two lamps 3, the second terminal plate 22 is fixed to the second end portion 3b of the first lamp 3, and the third terminal plate 23 is fixed to the second end portion 3b of the second lamp 3.
The plurality of lamps 3, 3 are arranged in parallel in a direction along the terminal plates 21 to 23 (particularly the first terminal plate 21). The lamp unit 2 further includes a holder 24 for holding the second end portions 3b and 3b of the two lamps 3 and 3.
The device (image forming apparatus in the present embodiment) 10 to which the lamp unit 2 is attached includes a plurality of fixing mechanisms 11 to which the terminal plates 21 to 23 are fixed, respectively. The fixing mechanism 11 includes bolts 12 and a support portion 13 screwed with the bolts 12 to support the terminal plates 21 to 23. The support portion 13 is supplied with power from a power source and supplies power to the lamp 3 through the terminal blocks 21 to 23.
The bolt 12 includes a male screw 121 and a head 122 formed wider (larger in diameter) than the male screw 121. The support portion 13 includes female threads 131 to be screwed with the male threads 121 of the bolt 12, and a flat surface portion 132 formed in a flat shape. The terminal plates 21 to 23 are held between the head portion 122 of the bolt 12 and the flat surface portion 132 of the support portion 13 and are fixed to the device 10.
As shown in fig. 2 to 4, the lamp 3 includes: a pipe body 4 having sealing portions 41 at both ends to seal the inside; a light emitter 5 housed inside the tube 4; and a metal foil 6 embedded in the sealing portion 41. Further, the lamp 3 includes: a conductor 7 electrically connecting the light emitter 5 and the metal foil 6; and a lead bar 8 for electrically connecting the metal foil 6 and the terminal plates 21 to 23.
The pipe body 4 includes a cylindrical body 42 disposed between the sealing portions 41 and 41, and a protruding portion 43 protruding from the cylindrical body 42. The pipe body 4 is made of, for example, quartz glass or heat-resistant resin. In the present embodiment, a small amount of a halogen substance (for example, a mixture of bromine and chlorine) and an inert gas (for example, argon or nitrogen) are sealed inside the tube body 4. Namely, the lamp 3 is a halogen lamp.
The cylindrical body 42 is formed in a cylindrical shape. The axial direction D1 of the pipe body 4 coincides with the axial direction D1 of the cylindrical body 42. For example, the outer diameter of the cylindrical body 42 is 6 to 10mm, and the thickness of the cylindrical body 42 is 0.8 to 1.2 mm.
The seal portion 41 is formed in a flat plate shape. The seal portion 41 is arranged along the axial direction D1 of the pipe body 4. Specifically, the seal portion 41 is arranged parallel to an imaginary plane parallel to the axial direction D1 of the pipe body 4.
Further, the width of the seal portion 41 is larger than the outer diameter (width) of the cylindrical body 42 when viewed in the axial direction D1 of the pipe body 4. For example, the width of the sealing portion 41 is 8 to 12 mm. Thus, when viewed in the axial direction D1 of the pipe body 4, a part (specifically, both end portions) of the seal portion 41 protrudes from the tubular body 42. The sealing portions 41 and 41 of the two lamps 3 and 3 are arranged in parallel.
The protruding portion 43 protrudes from the center of the cylindrical body 42 in the longitudinal direction in the radial direction of the pipe body 4. The protruding portion 43 is a remaining portion of the gas exhaust introduction pipe provided to discharge unnecessary gas from the inside of the tube body 4 and introduce gas into the inside of the tube body 4 in the manufacturing process of the lamp 3. For example, the protruding portion 43 is also referred to as "exhaust gas introduction pipe remaining portion" or "tip portion". The protruding portion 43 protrudes from the cylindrical body 42 toward the adjacent lamp 3.
The light emitter 5 is disposed inside the tube 4 so as to extend in the axial direction D1 of the tube 4. For example, the light emitter 5 is formed by a filament made of tungsten or the like. In the present embodiment, the light emitting body 5 functions as a heat generating body that generates heat.
The metal foil 6 is formed in a flat plate shape. The metal foil 6 is arranged along the axial direction D1 of the pipe body 4. Specifically, the metal foil 6 is arranged parallel to an imaginary plane parallel to the axial direction D1 of the tube body 4. The metal foil 6 is arranged in parallel with the sealing portion 41. The metal foil 6 is formed of molybdenum, for example.
The wire bar 8 is arranged to extend in the axial direction D1 of the pipe body 4. The lead bar 8 projects outward from the inside of the sealing portion 41. The inner end portion 81 of the lead bar 8 is embedded in the seal portion 41 and fixed to the metal foil 6.
The outer end 82 of the lead bar 8 is fixed to the terminal plates 21 to 23. Specifically, the lead bars 8, 8 on the first end portions 3a, 3a sides of the two lamps 3, 3 are fixed to the first terminal plate 21, the lead bar 8 on the second end portion 3b of the first lamp 3 is fixed to the second terminal plate 22, and the lead bar 8 on the second end portion 3b side of the second lamp 3 is fixed to the third terminal plate 23. The outer end 82 of the lead bar 8 is fixed to the terminal plates 21 to 23 by, for example, welding.
The terminal plates 21 to 23 include holes 21a to 23a through which the bolts 12 (specifically, male screws 121) are inserted. The holes 21a to 23a are formed larger than the male screw 121 of the bolt 12 and smaller than the head 122 of the bolt 12.
The terminal plates 21 to 23 are formed in a flat plate shape. The terminal plates 21 to 23 are arranged along the axial direction D1 of the pipe body 4. Specifically, the terminal plates 21 to 23 are arranged parallel to an imaginary plane parallel to the axial direction D1 of the pipe body 4.
However, the metal foil 6 and the terminal plates 21 to 23 are arranged so as to obliquely cross each other when viewed along the axial direction D1 of the pipe body 4. Specifically, when viewed along the axial direction D1 of the pipe 4, the intersection angle θ 1 between the metal foil 6 and the terminal plates 21 to 23 is greater than 0 ° and less than 90 °. In the present embodiment, the intersection angle θ 1 between the metal foil 6 and the terminal plates 21 to 23 is 45 ° when viewed along the axial direction D1 of the pipe body 4.
The lamp unit 2 and the heating device 1 of the present embodiment are configured as described above, and the operation of the lamp unit 2 and the heating device 1 of the present embodiment will be described below with reference to fig. 5 and 6.
When manufacturing the lamp unit 2, for example, when manufacturing errors occur in the shape of the tube body 4 or in the positions where the terminal plates 21 to 23 are fixed to the lead bars 8, the positional relationship between the terminal plates 21 and 22(21 and 23) also causes manufacturing errors. In contrast, the positional relationship of the fixing mechanism 11 of the apparatus 10 is not changed.
Therefore, when such a manufacturing error occurs, stress acts on the metal foil 6 via the lead bar 8 when the terminal plates 21 to 23 are fixed to the device 10 by the fixing mechanism 11. For example, as shown in fig. 5, a stress F1 in the normal direction D3 of the terminal plate 21 or a stress F2 in the direction of the terminal plate 21 (in-plane direction of the terminal plate 21) acts on the metal foil 6.
However, when a stress in the normal direction to the metal foil 6 acts on the metal foil 6, the seal portion 41 having a weak strength is particularly weak and may be broken. Therefore, the metal foil 6 obliquely crosses the terminal plate 21. Accordingly, metal foil 6 also obliquely crosses stress F1 in normal direction D3 of terminal plate 21 and also obliquely crosses stress F2 in the direction along terminal plate 21.
Therefore, such stresses F1 and F2 can be suppressed from acting on the metal foil 6 in the normal direction. In order to cope with both the stress F1 in the normal direction D3 of the terminal plates 21 to 23 and the stress F2 in the direction of the terminal plates 21 to 23, the intersection angle θ 1 between the metal foil 6 and the terminal plates 21 to 23 is preferably 15 ° to 75 °, and more preferably 30 ° to 60 °, when viewed in the axial direction D1 of the tube body 4.
When the bolt 12 is screwed into the support portion 13, as shown in fig. 6, a large stress (torque) F3 in the direction of the terminal plate 21 is applied to the terminal plate 21 due to friction between the bolt 12 and the terminal plate 21. Thereby, stress F3 in the direction of terminal plate 21 acts on metal foil 6 via wire rod 8.
In contrast, the metal foil 6 obliquely crosses the terminal plates 21 to 23. Thereby, metal foil 6 obliquely crosses stress F3 in the direction along terminal plate 21. Therefore, such stress F3 can be suppressed from acting on the metal foil 6 in the normal direction. In order to cope with this large stress F3, the intersection angle θ 1 between metal foil 6 and terminal plates 21 to 23 is preferably 45 ° or less, and more preferably 30 ° or less, when viewed along the axial direction D1 of pipe body 4.
As described above, the heating device 1 of the present embodiment includes the lamp unit 2. The lamp unit 2 of the present embodiment includes at least one lamp 3 and terminal plates 21 to 23 connected to the lamp 3, and the lamp 3 includes: a tube body 4 having sealing portions 41 at both ends; a metal foil 6 embedded in the sealing portion 41; and a lead bar 8, wherein an inner end portion 81 of the lead bar 8 is fixed to the metal foil 6 and an outer end portion 82 of the lead bar 8 is fixed to the terminal plates 21 to 23, and the metal foil 6 is arranged to obliquely cross the terminal plates 21 to 23 when viewed along an axial direction D1 of the pipe body 4.
With this configuration, when the terminal plates 21 to 23 are fixed to the device 10, the stress F1 in the normal direction D3 of the terminal plates 21 to 23 and the stress F2 in the direction along the terminal plates 21 to 23 (in-plane direction of the terminal plates 21 to 23) act on the metal foil 6 via the lead bar 8. On the other hand, when viewed along the axial direction D1 of the pipe body 4, the metal foil 6 obliquely intersects the terminal plates 21 to 23.
This can suppress the stress F1 in the normal direction D3 of the terminal plates 21 to 23 and the stress F2 in the direction along the terminal plates 21 to 23 from acting on the metal foil 6 in the normal direction. Thus, when the terminal plates 21 to 23 are fixed to the device 10, the sealing portion 41 can be prevented from being damaged.
In the lamp unit 2 according to the present embodiment, the tubular body 4 includes the tubular body 42 disposed between the sealing portions 41 and 41, the sealing portion 41 is formed in a flat plate shape, the sealing portion 41 is formed such that a part thereof protrudes from the tubular body 42 when viewed in the axial direction D1 of the tubular body 4, the plurality of lamps 3 are provided, the lead bars 8 of the plurality of lamps 3 are fixed to the common terminal plate 21, and the sealing portions 41 of the plurality of lamps 3 are disposed in parallel.
According to the above configuration, the seal portion 41 is formed in a flat plate shape. When viewed in the axial direction D1 of the pipe body 4, a part of the seal portion 41 protrudes from the tubular body 42. In the plurality of lamps 3, the lead bar 8 is fixed to the common terminal plate 21, and the sealing portions 41 are parallel to each other, so that the sealing portions 41 and 41 can be prevented from interfering with each other. This can reduce the diameter of the (virtual) circumscribed circle of the plurality of lamps 3, thereby saving space.
For example, when the lamp unit 2 is housed inside the heating roller 1a as in the lamp unit 2 of the present embodiment, the inner diameter of the heating roller 1a can be reduced. As a result, for example, the internal space of the heating roller 1a is reduced, or the separation distance between the heating roller 1a and the lamp unit 2 is reduced, so that the heat efficiency of the heating roller 1a can be improved.
The lamp unit and the heating device are not limited to the configurations of the above embodiments, and are not limited to the above operational effects. It goes without saying that various modifications can be made to the lamp unit and the heating device without departing from the scope of the present invention. For example, it goes without saying that one or more of the configurations, methods, and the like of the embodiments may be arbitrarily selected from the configurations, methods, and the like of various modifications described below and employed.
In the lamp unit 2 of the above embodiment, the protruding portion 43 protrudes from the tubular body 42 toward the adjacent lamp 3. However, the lamp unit is not limited to such a structure. For example, as shown in fig. 7, the protruding portion 43 may protrude from the cylindrical body 42 so as to be separated from the adjacent lamp 3. In the lamp unit 2 of fig. 7, the diameter of the (virtual) circumscribed circle of the plurality of lamps 3 is larger than that of the lamp unit 2 of the above-described embodiment (fig. 4) due to the protruding portion 43.
In the lamp unit 2 of the above embodiment, the sealing portions 41 and 41 of the plurality of lamps 3 are arranged in parallel. However, the lamp unit is not limited to such a structure. For example, as shown in fig. 8, the sealing portions 41 and 41 of the plurality of lamps 3 may be arranged to intersect with each other.
In the lamp unit 2 of fig. 8, the sealing portions 41 and 41 interfere with each other, and therefore the plurality of lamps 3 and 3 are arranged slightly apart from the lamp unit 2 of the above embodiment. Therefore, in the lamp unit 2 of fig. 8, the diameter of the (virtual) circumscribed circle of the plurality of lamps 3 is larger than that of the lamp unit 2 of the above-described embodiment (fig. 4) and the lamp unit 2 of fig. 7.
In the lamp unit 2 of the above embodiment, the support portion 13 is supplied with power from the power supply and supplies power to the lamp 3 through the terminal blocks 21 to 23. However, the lamp unit is not limited to such a structure. For example, as shown in fig. 9, the lamp unit 2 may be provided with a connection unit 25 connected to a power line for supplying electric power, and the connection unit 25 may be disposed so as to protrude from the terminal plate 21.
The lamp unit 2 of the above embodiment includes two lamps 3. However, the lamp unit is not limited to such a structure. For example, the lamp unit 2 may include one or three or more lamps 3.
In the lamp unit 2 of the above embodiment, the terminal plates 21 to 23 include the holes 21a to 23a, and are fixed to the device 10 by the bolts 12. However, the lamp unit is not limited to such a structure. For example, the terminal plates 21 to 23 may be fixed to the device 10 by welding, or may be fixed to the device 10 by being sandwiched between a pair of clamp-like clamping bodies.
The lamp unit 2 of the above embodiment is used in the heating device 1. However, the lamp unit is not limited to such a structure. For example, the lamp unit 2 may be configured to be used in a so-called light source device that utilizes generated light rather than generated heat.
The heating device 1 of the above embodiment is used in a fixing device of the image forming apparatus 10. However, the heating device is not limited to such a structure. For example, the heating device may be used as a heat source for heating or heat-insulating electric products for home use, precision equipment for business use or experiment use, equipment for chemical reaction, or the like.
