  Embodiments of a roller packing support member according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a plan view of a roller packing support member according to the present invention, and FIG. 2 is a cross-sectional view of the roller packing support member shown in FIG. In FIG. 1, reference numeral 1 denotes a rectangular plate-shaped body made of paper cardboard or plastics cardboard or the like, and 2 and 2 are a pair of holding bodies made of foamed resin. The pair of holding bodies 2 and 2 are fixed to and integrated with the rectangular plate-like body 1 by fixing means such as an adhesive.

  In the roller packing support member shown in FIGS. 1 and 2, the temporary assembly 3 shown in FIGS. 3 (a) and 3 (b) is stretched over and held by the holding bodies 2 and 2. . The temporary assembly 3 includes three roller members 4, 5, 6 having different diameters and a flexible (or elastic) cylindrical member 7. The cylindrical member 7 is used for, for example, a fixing belt of an image forming apparatus.

  A pair of shaft portions 4a, 4a, 5a, 5a, 6a, 6a is provided at both ends of each roller member 4, 5, 6. The outer diameter of the pair of shaft portions 4a is smaller than the outer diameter (maximum shaft diameter) of the shaft portion 5a and larger than the outer diameter (minimum shaft diameter) of the shaft portion 6a.

  As shown in FIG. 4, the pair of holding bodies 2, 2 has support portions 8, 9, 10 that support the shaft portions 4 a, 4 a, 5 a, 5 a, 6 a, 6 a of the roller members 4, 5, 6. Is formed. The support portion 8 includes a guide cutout 8a corresponding to the shaft portions 4a and 4a and a semicircular arc support wall 8b. The support portion 9 has a guide cutout 9a corresponding to the shaft portions 5a and 5a and a semicircular arc support wall 9b. The support part 10 is located between the support part 8 and the support part 9, and has a guide notch 10a and a guide slit 10b. The end of the guide slit 10b in the extending direction is a support wall 10c that supports the shaft portion 6a.

  The height H1 from the bottom portion 2a of the pair of holding bodies 2 and 2 to the upper end 2b of the support portion 8 and the height H1 from the bottom portion 2a to the upper end 2c of the support portion 9 are the same height. The height H2 from the bottom 2a of the 2 to the upper end 2d of the support 10 is designed to be lower than the height H1.

  As shown in FIG. 5, the temporary assembly 3 is such that the roller member 6 is positioned between the roller member 4 and the roller member 5, and the cylindrical member 7 is tensioned by the roller member 4 and the roller member 5. It is held by the pair of holding bodies 2 and 2 in a given state.

  The maximum dimension A in the height direction of the cylindrical member 7 when the temporary assembly 3 is held by the pair of holding bodies 2 and 2 is here H1 = A + 20 (unit mm). In this embodiment, since the height H1 is set to be about 20 mm larger than the maximum dimension A in the height direction of the cylindrical member 7, a margin space can be secured in the vertical direction of the packing support member for rollers. Even when packing support members are stacked in the vertical direction and packed and transported, the bottom surface 1a of the rectangular plate-like body 1 of the stacked packing support members for rollers is the outer peripheral surface of the cylindrical member 7 during transportation. When the outer peripheral surface of the cylindrical member 7 is rubbed or damaged, the upper surface 1b of the rectangular plate-like body 1 of the packing support member for rollers that directly supports the cylindrical member 7 on the outer peripheral surface of the cylindrical member 7 Can prevent the outer peripheral surface of the cylindrical member 7 from being rubbed or damaged during transportation.

  In this embodiment, for example, with A = 40 (mm) and H1 = 60 (mm), the margin space in the vertical direction can be 10 (mm) at a time, and the vertical space can be sufficiently secured. Thus, the outer peripheral surface of the cylindrical member 7 can be prevented from being damaged or damaged.

  On the other hand, when H1 = A + 10 (mm), if the vertical space is 5 (mm), the spatial margin of the outer peripheral surface of the cylindrical member 7 with respect to the rectangular plate 1 is reduced. There is an increased risk that the outer peripheral surface of the cylindrical member 7 will come into contact with the rectangular plate-like body 1 due to vibration, impact, etc. during conveyance in a state where the temporary assembly 3 is supported by the roller packing support member. In addition, the problem that the outer peripheral surface of the cylindrical member 7 is rubbed or damaged increases.

  On the other hand, if H1 = A + 30 (mm), the sufficient vertical space can be secured. However, when the roller packing support members are stacked and packed in the packing box or outer box, This reduces the transportation efficiency.

  Since the height H2 is lower than the height H1, when the temporary assembly 3 is removed from the packing support member for rollers, the arrangement of the roller members 4, 5, 6 with respect to the cylindrical member 7 is maintained. The temporary assembly 3 can be removed from the packing support member for rollers.

  For example, as shown in FIG. 5, in a state where the temporary assembly 3 is held by the packing support member for rollers, the shaft portion 6a of the roller member 6 is pulled out of the holding body 2 and held in the guide cutout 10a. Temporary holding, and then holding the roller members 4 and 5 and removing them from the roller packing support member so that the arrangement of the roller members 4, 5 and 6 with respect to the cylindrical member 7 is maintained, and the temporary assembly 3 can be removed from the roller packing support member without applying a force to the cylindrical member 7.

  In this embodiment, H2 = 50 (mm) is designed. Therefore, as shown in FIG. 4, the difference H3 between the height H1 and the height H2 is H3 = H1-H2 = 10 (mm). The height from the bottom 2a to the center O1 of the shaft 4a of the roller member 4 and the height from the bottom 2a to the center O2 of the shaft 5a of the roller member 5 are the same, and the distance Z from the centers O1 and O2 to the upper end 2d In this case, Z> H3. In this embodiment, for example, Z = 20 (mm).

  Thus, since the height H2 is designed to be lower than the height H1 and the distance Z is designed to have a large difference H3, for example, when the temporary assembly 3 is supported on the roller packing support member, Hold the shaft portion 6a of the roller member 6 in the hand and temporarily hold it in the guide notch 10a of the support portion 10, and then hold the roller members 4 and 5 in the hand to the guide notches 8a and 9a of the support portions 8 and 9. The roller members 4 and 5 can be supported by the semicircular arc-shaped support walls 8b and 9b while being guided and pushed in without any difficulty and applying tension to the cylindrical member 7. Next, the shaft portion 6a of the roller member 6 is grasped and pushed into the guide slit 10b to be supported by the support wall 10c.

  In addition, since tension is applied to the cylindrical member 7, movement in the direction in which the shaft portions 4a and 5a of the roller members 4 and 5 come out of the guide cutouts 8a and 9a due to vibration and impact is suppressed during transportation. Then, the set body 3 is stably held by the roller packing support member, and the set is facilitated when the temporary assembly 3 is supported by the roller packing support member, and the temporary assembly 3 is removed from the roller packing support member. It is possible to facilitate the process.

  As shown in FIG. 3, the diameter B of the shaft portion 6 a of the roller member 6 is desirably 5 mm or less, can be guided to the guide slit 10 b steadily, and the roller member 6 can be stably attached to the holding body 2. Can be retained. Further, since the guide notch 10a is tapered, the shaft portion 6a can be easily guided to the guide slit 10b. In this embodiment, the diameter B of the shaft portion 6a is, for example, 4 mm. .

  The diameter of the shaft portion 4a of the roller member 4 is C (mm), and the dimension between the wall surfaces 8b 'and 8b "of the guide notch 8a shown in FIG. 4 is X (mm). 5 (mm) <C≤15 (mm ), It is desirable to satisfy (C−2 (mm)) ≦ X ≦ (C−0.5 (mm)).

  Thereby, the shaft part 4a of the roller member 4 can be guided to the guide cutout 8a without fail, and the roller member 4 can be stably held by the holding body 2.

  This is because, in the case of X <(C-2), when the shaft portion 4a of the roller member 4 is pushed into the guide cutout 8a, the force when removing the shaft portion 4a of the roller member 4 from the guide cutout 8a This is because there is an inconvenience that it becomes difficult to attach and remove. On the other hand, if X> (C-0.5), the roller member 4 tends to easily come out of the guide cutout 8a due to vibration, impact, etc. during transportation.

  In this example, C = 12, and X = 11.5.

  Here, as shown in FIG. 4, it passes through the center O1 of the semicircular arc support wall 8b and reaches the wall surface 8b ′ on the left side of the guide notch 8a with respect to the virtual line F that bisects the semicircular arc support wall 8b. And the dimension up to the right wall surface 8b ″ is 6 mm. This further prevents the shaft portion 4a from coming out of the semicircular arc-shaped support wall 8b. The dimension to the left wall surface 8b 'of the guide notch 8a with respect to the line F and the dimension to the right wall surface 8b "of the guide notch 8a with respect to the imaginary line F are equally 5.75 (mm) on the left and right. Also good.

  When X = 10 (mm), the dimension from the imaginary line F to the left wall surface 8b ′ of the guide cutout 8a may be 4 mm, and the dimension from the right wall surface 8b ″ may be 6 mm. It is good also as 5 mm.

  Further, the diameter of the shaft portion 5a of the roller member 5 is D (mm), the dimension between the wall surfaces 9b 'and 9b "of the guide notch 9a is Y (mm), and 15 (mm) <D≤35 (mm). In some cases, it is desirable to satisfy (D-4 (mm)) ≦ Y ≦ (D−1 (mm)).

  Thereby, the shaft portion 5a of the roller member 5 can be guided to the guide notch 9a without difficulty, and the roller member 5 can be stably held by the holding body 2.

  This is because, when Y <(D-4), when the shaft portion 5a of the roller member 5 is pushed into the guide cutout 9a, the force when removing the shaft portion 5a of the roller member 5 from the guide cutout 9a This is because there is an inconvenience that it becomes difficult to attach and remove. On the other hand, if Y> (D-1), the roller member 5 tends to easily come out of the guide cutout 9a due to vibration, impact, etc. during transportation.

  In this example, D = 20 and Y = 16.

  Here, as shown in FIG. 4, the left wall surface 9b ′ of the guide notch 9a with respect to a virtual line F ′ that bisects the semicircular arc support wall 9b through the center O2 of the semicircular arc support wall 9b. The dimension up to 8 mm and the dimension up to the right wall surface 9 b ″ are 8 mm. Thereby, it is possible to further prevent the shaft portion 5 a from coming out of the semicircular arc-shaped support wall 9 b. Y = In the case of No. 19, the dimension from the imaginary line F ′ to the left wall surface 9b ′ of the guide cutout 9a and the dimension from the imaginary line F ′ to the right wall surface 9b ″ of the guide cutout 9a are evenly left and right. 5 (mm) may be used, the dimension from the imaginary line F ′ to the left wall 9b ′ of the guide notch 9a is 9 mm, and the dimension from the imaginary line F ′ to the right wall 9b ″ of the guide notch 9a is 10 mm. The dimension up to the left wall surface 9b ′ with respect to the virtual line F ′ is the right wall surface. b may be set to be smaller than the size of the up ".
