Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a case in which a cleaning blade used for removing deposits from a rotating body such as a drum or a belt is housed for transportation or the like.

(Technical background of the invention and its problems) Such a cleaning blade usually has a rectangular blade that slides on the circumferential surface of a rotating body, and a pair of clamping bodies that sandwich and hold the blade. For example, it is incorporated into an electrophotographic copying machine to remove adhering toner from a drum.

Incidentally, a box-shaped case made of cardboard is conventionally known as a case for storing this type of cleaning blade for transportation or the like.

However, in such a cardboard case, there is a risk that the housed cleaning blade may swing within the case due to vibrations during transportation, and may slip out of the case. Therefore, it is conceivable that an inner lid with a shape that corresponds to the outer shape of the cleaning blade to be stored could be provided inside the case to prevent the stored cleaning blade from swinging. It takes a lot of time and effort to do this, and there are problems in terms of storage efficiency.

Therefore, it is desired to develop a cleaning blade storage case that can easily store the cleaning blade and prevent the stored cleaning blade from swinging.

(Purpose of the invention) An object of the invention is to provide a storage case suitable for storing a cleaning blade.

(Summary of the invention) The invention has a case body and a lid that fits into the case body, and has a guide groove for guiding protrusions such as tightening bolts of the cleaning blade to be stored in the case body. It is characterized by having been established.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.

FIG. 3 shows a cleaning blade 1 housed in a storage case according to the present invention. This cleaning blade 1 has a blade 1A made of a rectangular plate material, and a pair of substantially L-shaped clamping plates 1B, 1B that sandwich and hold one end side along the longitudinal direction of the blade 1A. Each pressure plate 1
B is provided with screw holes at predetermined intervals along its longitudinal direction, and is joined to each other by screwing a tightening bolt 1C into each screw hole. The head 1c of each tightening bolt 1C protrudes from the plate surface of one of the clamping plates 1B.

As shown in FIGS. 1 and 2, the storage case 2 of the present invention includes a case body 3 and a lid 4 made of a plastic material such as vinyl chloride. These case body 3 and lid body 4 are the cleaning blade 1 to be stored (see Figure 3).
The width dimension of the housing half parts 3A and 4A on which the blade 1A is arranged is slightly larger than the width dimension of the housing half parts 3B and 4B of the pinching plate 1B. There is. A guide groove 3b for guiding the head 1c of the tightening bolt 1C (see FIG. 3) is provided along the longitudinal direction of the storage half 3B of the case body 3, where the clamping plate 1B is disposed. ing. Furthermore, a groove 4b corresponding to the guide groove 3b is provided in the storage side half 4B of the lid body 4, in which a part of the pressure plate 1B is disposed. A plurality of locking protrusions 3c are formed in the vicinity of the storage opening 3a of the case body 3, and a plurality of locking protrusions 3c are formed inside the bulge of the lid body 4.
A plurality of locking recesses 4a are formed corresponding to c. When the bulge, which is approximately half of the lid 4, is fitted to the end of the case body 3 on the side of the storage opening 3a from the direction indicated by the arrow in FIG.
The locking recess 4a engages with the locking recess 4a, thereby fitting the lid 4 of the case body 3 in a closed state.

Next, the usage and operation of the storage case 2 of the present invention will be explained.

First, the operator holds the case body 3 with one hand, holds one end of the cleaning blade 1 to be stored with the other hand, and tightens the tightening bolt 1 with the other hand.
C is inserted into the case body 3 with its head 1c positioned at the guide groove 3b position.

Next, the lid 4 is fitted onto the case body 3 as described above.

Therefore, the cleaning blade 1 can be stored in the storage case 2 with good workability.

By the way, when the cleaning blade 1 is stored in the storage case 2 of the present invention, the head 1c of the tightening bolt 1C is located in the guide groove 3b as shown in FIG. Even if the cleaning blade 1 is applied, the cleaning blade 1 does not swing in the width direction within the storage case 2. Therefore, it is possible to effectively prevent the lid 4 from coming off from the case body 3 and the cleaning blade 1 from slipping out from the storage case 2 during transportation or the like.

Another cleaning blade 5 is shown in FIG. This cleaning blade 5 has a blade 5A formed in a pair of pressure plates 5B and 5B that are substantially in a straight line.
It is held in place by being held between the two. Each clamping plate 5B has a clamping part protruding in the thickness direction, and is joined to each other by a plurality of tightening bolts 5C, and the head 5c of each clamping bolt 5C protrudes from the plate surface of one clamping plate 5B. ing.

Now, as shown in FIG. 4, the case body 7 of the storage case 6 of the present invention that stores the cleaning blade 5 has a substantially central portion extending outward along the longitudinal direction, corresponding to the external shape of the cleaning blade 5. It stands out. Further, on one end side of the case body 7, a head 5c of a tightening bolt 5C is provided along the longitudinal direction.
A guide groove 7a is provided for guiding (see FIG. 5).

Also in this storage case 6, the head 5c of each tightening bolt 5C of the stored cleaning blade 5 is
is located in the guide groove 7a, and thus the clamping plates 5B, 5B
Since the protruding pinching portion is located on the protruding portion of the case body 7, it is possible to effectively prevent the cleaning blade 5 from coming off even if vibrations are applied during transportation. Note that a lid (not shown) is also fitted to this storage case 6.

(Effects of the invention) According to the invention, at least the case body of the storage case consisting of the case body and the lid is provided with a guide groove for guiding the protruding parts such as the tightening bolts of the cleaning blade to be stored. The cleaning blade can be easily stored, and the stored cleaning blade will not swing around inside the case, so even if vibrations or shocks are applied during transportation, the cleaning blade will not fall out of the storage case. can be effectively prevented.
