[0036] First, a packaging apparatus usable for both the
high-temperature compressor 1A and the low-temperature compressor
1B will be described.
[0037] In FIGS. 5 and 8, the packaging apparatus mainly comprises a
base board 20 such as a pallet formed of a wooden frame in which an
arm of a forklift is insertable, a lower plate 21 which is mounted
on the base board 20 and formed by adhesively attaching plural
cardboards, a first intermediate plate 22 in which the compressor
main bodies 2A (2B) are inserted and which are formed by adhesively
attaching plural cardboards, a second intermediate plate 23 which
are mounted on the upper portions of the end caps 3A (3B) and
formed by adhesively attaching plural cardboards, an upper plate 24
formed of laminated wood (plywood), paper cores which are engagedly
fitted in second fitting holes 31 of the second intermediate plate
23 under the state that the suspending portions 7A (7B) provided to
the end caps 3A (3B) are engagedly fitted in first fitting holes
30, a bag type waterproof and dust-proof plastic sheet 26 which has
an opened lower surface and covers the lower plate 21 on the base
board 20, the first intermediate plate 22, the second intermediate
plate 23 and the paper cores 25, and a binding band 27 for
integrally binding all the above constituent elements from the
lowermost base board 20 to the uppermost upper plate 24 under the
state that the lower plate 21 on the base board 20, the first
intermediate plate 22, the second intermediate plate 23 and the
paper cores 25 are covered by the plastic sheet 26 and the upper
plate 24 is placed on the plastic sheet 26.
[0038] Next, the lower plate 21 will be described below.
[0039] As shown in FIG. 5, the lower plate 21 is provided with
plural first fitting holes 32 and second fitting holes 33
intercommunicating with the first fitting holes 32 so as to extend
outwardly from the first fitting holes 32. Each first fitting hole
32 has a circular shape in plan view, and the spherical
(dish-shaped) convex surface portion of the end cap 4A (4B) of each
compressor 1A (1B) is engagedly fitted in each first fitting hole
32. Plural second fitting holes 33 (in this embodiment, four second
fitting holes 32) are formed so as to intercommunicate with each
first fitting hole 32 and disposed so as to be spaced from one
another at an angular interval of 90 degrees. The securing legs 5A
(5B) of each compressor 1A (1B) are engagedly fitted in the second
fitting holes 33.
[0040] One of four corners of the lower plate thus constructed is
cut out to form a cut-out portion 21A serving as an identifier.
When the lower plate is disposed so that the cut-out portion 21A is
located at the lower left side in FIG. 5, the lower plate 21 is
defined as being placed face up. In this case, the lower plate 21
is used to package plural high-temperature compressors 1A. When
this lower plate 21 is reversed, the lower plate 21 is defined as
being placed face down, and it is used to package plural
low-temperature compressors 1B.
[0041] In this case, the second fitting holes 33 are formed so that
each securing leg 5A is engagedly fitted in each second fitting
hole 33 under the state that the convex surface portion of the end
gap 4A of each high-temperature compressor 1A is engagedly fitted
in each first fitting hole 32 so that the outflow plug 1A is
located so as to be displaced from the vertical center line by 20
degrees, that is, located at the 160-degree position as shown in
FIG. 7. That is, each fitting hole 33 is formed so that the
securing leg 5A at the lower left side is engagedly fitted in the
second fitting hole 33 so as to be displaced from the vertical
center line by 25 degrees.
[0042] Next, the first intermediate plate 22 will be described.
[0043] The first intermediate plate 22 is provided with first
engaging holes 34 each having a circular shape and through which
the compressor main bodies 2A (2B) are inserted, second fitting
holes 35 each of which intercommunicates with each first fitting
hole 35 so as to extend outwardly from the first fitting hole 35
and through which the outflow plug 11A of each compressor 1A or the
outflow plug 11B of each compressor 1B is engagedly fitted
(inserted), third fitting holes 36 in which the take-out pipes 19B
of the compressors 1B are engagedly fitted, fourth fitting holes 37
in which the inlet pipe 18B of the compressors 1B are engagedly
fitted, and fifth fitting holes 38 in which the take-out pipes 17B
of the compressors 1B are engagedly fitted. One of four corners of
the first intermediate plate 22 is cut out to form a cut-out
portion 22A. When the first intermediate plate 22 is disposed so
that the cut-out portion 22A is located at the lower left side, the
first intermediate plate 22 is defined as being placed face up. In
this case, the first intermediate plate 22 is used to package
plural high-temperature compressors 1A. When this first
intermediate plate 22 is reversed, the first intermediate plate 22
is defined as being placed face down, and it is used to package
plural low-temperature compressors 1B.
[0044] Accordingly, under the state that the first intermediate
plate 22 is placed face up, the end cap 3A of each high-temperature
compressor 1A is passed through the first fitting hole 34 and the
outflow plug 11A is passed through the second fitting hole 35, and
then each compressor main body 2A and each end cap 3A are inserted
in the first intermediate plate 22. On the other hand, under the
state that the first intermediate plate 22 is placed face down, the
end gap 3B of each low-temperature compressor 1B is inserted in the
first fitting hole 34, the take-out pipe 19B is inserted in the
third fitting hole 36, the inlet pipe 18B is inserted in the fourth
fitting hole 37, and the take-out pipe 17B is inserted in the fifth
fitting hole 38, so that each compressor main body 2B and each end
cap 3B are inserted in the intermediate plate 22.
[0045] Next, the second intermediate plate 23 will be
described.
[0046] As described above, the second intermediate plate 23 is
provided with the second fitting holes 31 in which the paper cores
25 placed at the center portions on the end caps 3A (3B) are
fitted, and the first fitting holes 30 which intercommunicate with
the second fitting holes 31 so as to extend outwardly from the
second fitting holes 31 and are disposed so as to be spaced from
one another an angular interval of 90 degrees so that the
suspending portions 7A (7B) provided to each end cap 3A (3B) are
engagedly fitted in each first fitting hole 30. One of four corners
of the second intermediate plate 23 is cut out to form a cut-out
portion 23A. When the second intermediate plate 23 is disposed so
that the cut-out portion 23A is located at the lower left side, the
second intermediate plate 23 is defined as being placed face up. In
this case, the second intermediate plate 23 is used to package
plural high-temperature compressors 1A. When this second
intermediate plate 23 is reversed, the second intermediate plate 23
is defined as being placed face down, and it is used to package
plural low-temperature compressors 1B.
[0047] Accordingly, under the state that the second intermediate
plate 23 is placed face up, the paper core 25 mounted at the center
portion on the end cap 3A of each high-temperature compressor 1A is
engagedly fitted in the second fitting hole 31, and each pair of
suspending portions 7A provided at the symmetrical positions are
engagedly fitted in each pair of first fitting holes 30 provided to
the symmetrical positions. Under the second intermediate plate 23
is placed face down, the paper core 25 mounted at the center
portion on the end cap 3B of each low-temperature compressor is
engagedly fitted in the second fitting hole 31, and each pair of
suspending portions 7B provided at the symmetrical positions are
engagedly fitted in the other pair of first fitting holes 30
provided at the symmetrical positions.
[0048] The base board 20, the lower plate 21, the first and second
intermediate plates 22 and 23 and the upper plate 24 are designed
to be substantially equal to one another in size in plan view.
[0049] Next, a manner of packaging plural high-temperature
compressors 1A by using the compressor packaging apparatus
described above will be first described.
[0050] First, the lower plate 21 which is placed face up is mounted
on the base board 20 so that the cut-out portion 21A is located at
the lower left side as shown in FIG. 6. The spherical convex
surface portion of the end cap 4A of each high-temperature
compressor 1A is engagedly fitted in each first fitting hole 32 of
the lower plate 21, the annular flat portion in the neighborhood of
the peripheral edge portion of the end cap 4A is mounted on the
peripheral portion of the first fitting hole 32 and the four
securing legs 5A are engagedly fitted in the second fitting holes
33, whereby the compressors 1A can be prevented from being rotated
on the plane (in the plane direction).
[0051] Subsequently, in order to prevent the movement in the
horizontal direction of each high-temperature compressor 1A mounted
on the lower plate 21, the first intermediate plate 22 which is
placed face up is put from the upper side of the compressors 1A so
that the cut-out portion 22A of the first intermediate plate 22 is
located at the lower left side. Then, each compressor main body 2A
is inserted through the first fitting hole 34, and the outflow plug
11A on the side surface of the end cap 3A is inserted through the
second fitting hole 35, and the first intermediate plate 22 is
moved to the position as indicated by a two-dotted chain line of
FIG. 7. The first intermediate plate 22 can surely prevent the
movement in the horizontal (plane) direction of the compressors 1A.
With respect to the packaging of the high-temperature compressors
1A, the third fitting holes 36, the fourth fitting holes 37 and the
fifth fitting holes 38 play no role when the compressor main bodies
2A are inserted through the first fitting holes 34.
[0052] Subsequently, the second intermediate plate 23 is placed
face up on the end caps 3A of the compressors 1A so that the
cut-out portion 23A is located at the lower left side and pressed
from the upper side so that the respective suspending portions 7A
are engagedly fitted in the corresponding first fitting holes 30,
and then the second intermediate plate 23 is moved to the position
indicated by a two-dotted chain line of FIG. 7. However, in this
case, the upper end portions of the suspending portions 7A do not
project upwards from the second intermediate plate 23 (see FIG. 7).
When the second intermediate plate 23 is moved, the other pair of
first fitting holes 30 at the symmetrical positions play no role.
Under this state, the paper cores 25 are engagedly fitted in the
second fitting holes 31 of the second intermediate plate 23. The
paper cores 25 are designed to be longer than the second
intermediate plate 23 in the thickness direction thereof, and
project upwards from the second intermediate plate 23.
[0053] Subsequently, the plastic sheet 26 is put to cover the
constituent elements from the second intermediate plate 23 to the
lower plate 21, and then the upper plate 24 is placed on the
plastic sheet 26. Thereafter, all the constituent elements from the
upper plate 24 to the base board 20 are fixedly bound by the
binding belt 27 so as to be integral with each other (see FIG.
8).
[0054] As described above, under the state that each compressor
main body 2A is inserted in the first intermediate plate 22, the
second intermediate plate 23 is placed on the end caps 3A, each
suspending portion 7A is engagedly fitted in the corresponding
first fitting hole 30, the paper cores 25 are engagedly fitted in
the second fitting holes 31, and the compressors 1A are fixedly
sandwiched between the lower plate 21 and the upper plate 24.
Particularly, the second intermediate plate 23 and the paper cores
25 contribute to prevent occurrence of clearance when the
compressors 1A are fixedly sandwiched between the lower plate 21
and the upper plate 24, thereby surely fixing the compressors
1A.
[0055] Next, a manner of packaging plural low-temperature
compressors 1B will be described.
[0056] First, the lower plate 21 is reversed and placed face down
on the base board 20 so that the cut-out portion 21A is located at
the lower right side. Then, the spherical convex surface portion of
the end cap 4B of each low-temperature compressor 1B is engagedly
fitted in the first fitting hole 32 of the lower plate 21, the
annular flat portion in the neighborhood of the peripheral edge
portion of the end cap 4B is mounted on the peripheral edge portion
of the first fitting hole 32, and the four securing legs 5B are
engagedly fitted in the corresponding second fitting holes 33,
whereby the rotation of the compressors 1B on the plane (in the
plane direction) can be prevented.
[0057] Subsequently, the first intermediate plate 22 is reversed
and placed face down, and put on the upper side of the compressors
1B so that the cut-out portion 22A is located at the lower right
side. The compressor main bodies 2B are inserted through the first
fitting holes 34, the outflow plugs 11B are inserted through the
second fitting holes 35, the take-out pipes 19B are inserted
through the third fitting holes 36, the inlet pipes 18B are
inserted through the fourth fitting holes 37, the take-out pipes
17B are inserted through the fifth fitting holes 38, and the first
intermediate late 22 is moved to the position indicated by the
two-dotted chain line of FIG. 11. By the first intermediate plate
22, the movement of the compressors 1B in the plane direction can
be surely prevented.
[0058] Subsequently, the second intermediate plate 23 is reversed
and placed face down so that the cut-out portion 23A is located at
the lower right side, pressed from the upper side so that the
suspending portions 7B are engagedly fitted in the corresponding
first fitting holes 30 and moved to the position indicated by a
two-dotted chain line of FIG. 11. In this case, the upper end
portions of the suspending portions 7B are prevented from
projecting upwards from the second intermediate plate 23 (see FIG.
11). When the second intermediate plate 23 is moved, the pair of
first fitting holes 30 in which the suspending portions 7A are
fitted play no role. Under this state, the paper cores 25 are
engagedly fitted in the second fitting holes 31 of the second
intermediate plate 23. In this case, the paper cores 25 are
designed to be longer than the second intermediate plate 23 in the
thickness direction thereof, and thus project upwards from the
second intermediate plate 23.
[0059] Subsequently, the plastic sheet 26 is put to cover the
constituent elements from the second intermediate plate 23 to the
lower plate 21, the upper plate 24 is placed on the plastic sheet
26, and then all the constituent elements from the upper plate 24
to the base board 20 are fixedly bound by the binding band 27 so as
to be integral with one another (see FIG. 12).
[0060] As described above, under the state that the compressor main
bodies 2B are inserted through the first intermediate plate 22, the
second intermediate plate 23 is placed on the end caps 3B, the
suspending portions 7B are fitted in the corresponding first
fitting holes 30, and then the paper cores 25 are engagedly fitted
in the second fitting holes 31, whereby the compressors 1B are
fixedly sandwiched between the lower plate 21 and the upper plate
24. Particularly, the second intermediate plate 23 and the paper
cores 25 prevent occurrence of clearance when the compressors 1B
are fixedly sandwiched between the lower plate 21 and the upper
plate 24, and contribute to the fixedly packaging of the
compressors.
[0061] In the compressor packaging apparatus described above, the
compressors 1A and 1B can be surely prevented from being damaged
due to vertical vibration or swinging motion when they are
transported. Furthermore, when two kinds of compressors having
substantially the same size are packaged, by providing only one
kind of intermediate plate (each of first and second intermediate
plates) and only one kind of lower plate and selectively placing
these elements face up or face down, the compressor packaging
apparatus having a low manufacturing cost can be provided.
[0062] The present invention is not limited to the above-described
embodiment, and various alternatives, alterations and modifications
of this embodiment can be made by persons skilled in the art, and
thus the present invention contains these various alternatives,
alterations and modifications without departing from the subject
matter of the present invention.
