JP, 2009-196542, A

  In the container with the conventional canopy opening / closing device as described above, minute manufacturing errors such as the length of the arm supporting the canopy, the bracket supporting the one end of the arm, and the pin connecting the canopy and the other end of the arm are accumulated Thereby, when the pair of canopy is closed, individual differences may occur in the closed posture of each canopy. If such individual differences occur, the upper surface of the seal is not disposed parallel to the back surface of the canopy in the closed position, and the seal surface pressure between the canopy and the seal may be reduced.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide a container with a lid opening / closing device capable of suppressing reduction in seal surface pressure between the lid and seal in a closed posture even if manufacturing errors occur. With the goal.

  The container with lid opening / closing device according to the present invention comprises a container body having an opening at an upper portion, a pair of canopy that divides and closes the opening in one direction, a pair of canopys, and a closing posture that closes the opening. An open / close device for opening and closing between the open position and the open position, and the peripheral portion of the opening of the container body extends along the one direction, and between the canopy and the peripheral portion in the closed position It is characterized by comprising a one way seal that seals and a support mechanism that supports the one way seal vertically adjustably with respect to the peripheral edge.

  According to the container provided with the opening / closing device, the one-way seal for sealing between the canopy which divides and closes the opening of the container body in one direction and the peripheral portion of the opening of the container body is the peripheral edge by the support mechanism. It is supported for position adjustment in the vertical direction with respect to the unit. Thereby, when the upper surface of the one-way seal is not disposed parallel to the back surface of the canopy in the closed posture due to a manufacturing error, the one-way seal is vertically adjusted with respect to the peripheral portion. The top surface of the one way seal may be disposed parallel to the back of the canopy. As a result, it is possible to suppress a decrease in seal surface pressure between the canopy in the closed position and the one-way seal.

  The container with lid opening / closing device further includes a guide roller provided on an upper portion of the container main body and slidably supporting the lid, and the supporting mechanism is an erected portion which is erected on the peripheral edge and extends in one direction. And a plurality of bolts for attaching the one-direction seal and extending in the one direction, and a plurality of bolts for attaching the plurality of supports to the screen, the canopy in the closed position An outer end portion in a direction is supported by the guide roller, and an inner end portion in the one direction is disposed so as to be vertically swingable, and a bolt through which each of the bolts is inserted into the projection portion A plurality of holes are formed in the one direction, and the plurality of bolt holes are formed in a round hole formed on the outermost side in the one direction and vertically longer in the one direction than the round hole. And a predetermined number of long holes which are, consist preferably.

  In this case, the canopy in the closed posture is disposed in a state in which the inner end in one direction can be vertically swung about the support position of the guide roller at the outer end in the one direction. For this reason, the closed posture of the canopy is subject to individual differences in the amount of vertical swing at the inner end in the one direction due to a manufacturing error. However, even if such individual differences occur, the support portion can be vertically moved by loosening the plurality of bolts and moving the bolts inserted through the long holes in the vertical direction along the long holes of the screen portion. Position can be adjusted in the direction. At this time, since the outer end of the support in one direction is fixed in position by the bolt inserted into the round hole of the projection, the closed end is centered on the outer end in the one direction of the support, that is, a closed posture It is possible to adjust the position while vertically swinging the one end of the supporting portion in the vertical direction, centering on the supporting position side (the swinging center side) of the canopy. Thereby, position adjustment which arranges the upper surface of a one way seal in parallel to the back of a canopy can be performed easily.

  The container with a canopy opening and closing device extends along the other direction crossing the one direction from the proximity position of the one end of the one direction seal at the peripheral edge portion, and the canopy with the closed posture It is possible to connect an opposite direction seal that seals between the peripheral portion, an end portion to which the one direction outer end of the one direction seal can be connected, and an end portion on the one direction seal side of the other direction seal Preferably, it further comprises an L-shaped connecting seal having the other end.

  In this case, since the adjacent ends of the one-way seal and the other-direction seal disposed to intersect with each other are connected via the L-shaped connection seal, when the one-way seal is vertically aligned In addition, the connection seal can absorb the step difference between the adjacent ends of the one-direction seal and the other-direction seal. Therefore, even if the one-way seal is adjusted in the vertical direction, it is possible to suppress the decrease in seal performance between the adjacent ends of the one-way seal and the other seal.

In the container with lid open / close device, a first port is formed at one of the one end of the one-direction seal and the one end of the one end of the connection seal. A first insertion portion to be inserted into the first receiving portion is formed at the one end of the one-direction seal and the other end of the one end of the connection seal. Is preferred.
In this case, by inserting the first insertion portion formed at the other end into the first receiving portion formed at one end of the one-direction seal and the connection seal, the one-direction seal is formed. The ends of the seal and the connection seal can be easily connected. Thereby, even if the dimension change in the one direction occurs in the opening of the container body, it can be easily coped with by replacing it with the one-way seal having a length corresponding to the dimension change.

In the container with lid open / close device, a second socket is formed at an end of the other direction seal on the one-direction seal side and one end of the other end of the connection seal. A second insertion portion inserted into the second receiving portion at the other end of the one end of the other direction seal and the other end of the other end of the connection seal Preferably, a part is formed.
In this case, the other direction seal is obtained by inserting the second insertion portion formed at the other end into the second socket formed at one end of the other seal and the connection seal. And the ends of the connection seal can be easily connected. Accordingly, even if the dimension change in the other direction occurs in the opening of the container main body, it can be easily coped with by replacing it with the other direction seal having a length corresponding to the dimension change.

In the container with lid open / close device, preferably, the connection seal has a hollow portion inside, and the hollow portion is provided with a reinforcing member that suppresses deformation of the connection seal.
In this case, when the back surface of the canopy in the opening / closing operation is in sliding contact with the connection seal, the reinforcing member provided in the hollow portion of the connection seal can suppress deformation of the connection seal.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[overall structure]
FIG. 1 is a plan view of a container with a canopy opening and closing device according to an embodiment of the present invention. FIG. 2 is a side view of the container with a canopy opening and closing device. Hereinafter, in the present embodiment, the left side of FIG. 1 is referred to as “front side”, and the right side of FIG. 1 is referred to as “rear side”. Moreover, the upper side of FIG. 1 is called "left side", and the lower side of FIG. 1 is called "right side." Therefore, in the present embodiment, the left-right direction in FIG. 1 is the “front-rear direction”, and the top-bottom direction in FIG. 1 is the “left-right direction”.

  In FIG. 1 and FIG. 2, the container 1 with a lid opening / closing device of the present embodiment (hereinafter, also simply referred to as “container 1”) has a container main body 2 having an opening A at the top, and the opening A in the lateral direction And a pair of canopys 5 which are divided and closed. The container main body 2 is formed in a box shape between four columns 3 provided on the front, rear, left and right. At the rear of the container body 2, there is provided a shed 4 (only shown in FIG. 2) for dumping.

  FIG. 3 is a front view of the container 1 as viewed from the front. Moreover, FIG. 4 is the rear view which looked at the container 1 from back. In FIG. 3 and FIG. 4, the pair of canopy 5 is in a slightly inclined state so as to form a mountain-shaped roof of the container 1 in a state in which the opening A is closed.

  In FIG. 1 (see also FIGS. 2 to 4), the container 1 has a pair of canopy 5 in a closed posture (FIG. 3 and FIG. 6) closing the opening A and an open posture (FIG. 8) opening the opening A And an opening / closing device 6 which is operated to open / close between them. The opening / closing device 6 of the present embodiment is mainly configured by an arm 7, a pulley 9, a motor 11, chains 12 and 13, a connecting shaft 14, and a spring cylinder 15. Directly opening and closing the canopy 5 is a pair of front and rear arms 7. A shaft 8 is fixed to the proximal end of each arm 7, and the shaft 8 is rotatably supported by a bracket 10 mounted on the container body 2.

  Each arm 7 pivots about an axis 8 and is connected to the canopy 5 at the tip end of the pivot. The front left shaft 8 is a drive shaft 8A rotationally driven by a motor 11 attached to the container body 2. The other axis 8 is a mere spindle.

  The left and right arms 7 interlock with the pulley 9 fixed to the shaft 8 by means of a chain 12 (FIGS. 3 and 4) stretched in a figure of "8". The front and rear arms 7 are also interlocked via a chain 13 (FIGS. 3 and 4) and a connecting shaft 14 (FIGS. 1 to 4). Therefore, the pair of canopy 5 is synchronously opened and closed by the pair of front and rear arms 7 based on the operation of the motor 11. The pair of canopy 5 completes the closing operation (see FIGS. 3 and 4) when the pivoting tips of the pair of left and right arms 7 abut each other (see FIGS. 3 and 4) and assumes a closed posture in which the opening A is fully closed.

  The piston rod 15 b of the spring cylinder 15 is connected to the drive shaft 8 A via the connection member 16. The proximal end of the cylinder tube 15 a of the spring cylinder 15 is pivotally attached to a bracket 17 fixed to the container body 2. The piston rod 15b is urged in a direction to be drawn into the cylinder tube 15a by a compression spring (not shown) provided in the cylinder tube 15a. The spring cylinder 15 is pivotable about the pivot point P in FIG.

  FIG. 5 is an enlarged view of a portion I in FIG. In FIG. 5, a guide roller 29 is provided around a central axis of a bracket 30 (see also FIG. 3) erected on the front side of the upper portion of the container body 2 and on the left side (peripheral side of the opening A). It is rotatably mounted. The guide roller 29 is in rolling contact with the front end edge of the back surface of the canopy 5 to guide the canopy 5 in the tangential direction. As shown in FIG. 4, a guide roller 29 is rotatably attached to the rear of the upper portion of the container body 2 via a bracket 30. The guide roller 29 slidably supports the rear end edge of the back surface of the canopy 5 and guides the canopy 5 in the tangential direction.

  FIG. 6 is a front view showing the pair of canopy 5 in the closed position. In the closed posture of the canopy 5, the pivoting tips of the pair of left and right arms 7 abut on each other. The arm 7 is pivotable about the drive shaft 8A as described above, and the pivoting tip of the arm 7 is rotatably coupled to the inner end of the canopy 5 by the pin 32. The back surface of the outer end of the canopy 5 is supported by the guide roller 29 as described above. Further, an engagement pin 33 (see also FIG. 5) is provided in a projecting manner at the outer end of the canopy 5, and the engagement pin 33 is engaged with an engagement groove 30b provided on the bracket 30. . Thus, the canopy 5 is arranged such that the outer end portion is supported by the guide roller 29 and the inner end portion can be swung vertically in the closed position.

  On the other hand, the tip end of the piston rod 15 b of the spring cylinder 15 is connected to one end of the connecting member 16 via a pin 34. The connecting member 16 is fixed to the drive shaft 8A and rotates with the arm 7. When the canopy 5 is in the closed position, the drive shaft 8A exists on a substantially extended line of the central axis of the piston rod 15b, and the biasing force of the spring cylinder 15 attempting to pull in the piston rod 15b rotates the drive shaft 8A. Does not generate torque. Therefore, the other arms (the left arm 7 and the rear pair of arms 7) interlocked with the arm 7 do not generate any torque, and the canopy 5 is stable by its own weight in the closed position.

  From the state of FIG. 6, when the motor 11 (FIG. 1) is operated to turn the right arm 7 in the clockwise direction with the drive shaft 8A, the left arm 7 synchronizes and stands up via the chain 12 The rear arm 7 also synchronously starts to rotate in the standing direction via the chain 13.

  FIG. 7 is a front view showing a state in which the arm 7 is in the middle of rotation. As shown in FIG. 7, when the arm 7 pivots in the standing direction, the inner end of the canopy 5 is lifted and the outer end of the canopy 5 slides on the guide roller 29. As the arm 7 and the drive shaft 8A rotate, the connecting member 16 also rotates, and as a result, the piston rod 15b is slightly pulled out against the compression spring in the cylinder tube 15a. Therefore, although a driving force in the closing direction is also applied to the arm 7, this driving force is smaller than the driving force in the opening direction applied to the arm 7 by the motor 11.

  When the arm 7 further pivots from the state of FIG. 7, as shown in FIG. 8, the arm 7 falls outward, and the canopy 5 hangs vertically almost vertically on the outside of the container body 2. Thus, the canopy 5 is completely opened, and the opening A of the container body 2 is fully opened. In this state, the motor 11 is stopped. In this state, the piston rod 15b is largely pulled out against the compression spring in the cylinder tube 15a, and a driving force in the closing direction is applied to the arm 7 through the connecting member 16. Although this driving force is larger than the state of FIG. 8, the canopy 5 is stabilized in the state of FIG. 8 because the weight of the canopy 5 is smaller.

  The closing operation of the canopy 5 is performed by the operation reverse to the above. When the canopy 5 starts the closing operation from the open position in FIG. 8, the load on the motor 11 is reduced by the driving force in the closing direction by the spring cylinder 15. In addition, the arm 7 can be locked in the state which closed the canopy 5 by the lock device which abbreviate | omitted illustration.

[Periphery before and after opening]
FIG. 9 is a plan view of the container body 2 with the canopy 5 and the opening / closing device 6 omitted. FIG. 10 is a front view of the container body 2 of FIG. In FIG. 9 and FIG. 10, on the front and rear peripheral edge portions of the opening A of the container main body 2, an upright portion 41 is provided upright on the upper surface of the container main body 2. These partition parts 41 are formed in the integral rectangular frame shape with the partition part 51 mentioned later.

  Each of the screen portions 41 is a flat plate member extending over the entire length of the opening A in the left-right direction (see also FIG. 11), and the upper end face thereof corresponds to the closed posture of the pair of canopy 5 (see FIG. 6). It is inclined and formed so that it may become a mountain shape in front view. A rubber packing 21 as a "one-way seal" extending along the left-right direction (one direction) is attached to the upper end portion of each screen 41 through a support 42 described later. The packing 21 shown in FIGS. 9 and 10 is hatched for convenience of illustration.

  11 is a cross-sectional view taken along the line II-II in FIG. In FIG. 11, the packing 21 has a base 21a attached to a rail 44 described later, and a main body 21b integrally formed on the upper part of the base 21a. The main body portion 21b is formed in a tubular shape, and has a hollow portion 21c inside. The back surface of the canopy 5 is in contact with the upper surface of the main body 21b. Thereby, the packing 21 seals between the canopy 5 in the closed position and the front and rear peripheral portions of the opening A of the container body 2.

  A pair of left and right support portions 42 to which the packing 21 is attached is attached to the upper end portion of the front surface of the screen portion 41 (see also FIG. 10). Further, a reinforcing material 50 for reinforcing the peripheral portion of the support portion 42 in the partition portion 41 is fixed to the rear surface of the partition portion 41. The reinforcing member 50 is made of, for example, an angle member, and is disposed below the washer 47 described later.

  The support portion 42 is constituted of, for example, a support plate 43 made of an angle material and a rail 44 fixed to the support plate 43. The support plate 43 and the rails 44 of each support portion 42 are formed to extend in the left-right direction from the outer end portion of the partition portion 41 toward the inner end portion (central portion). A rail 44 is mounted on the upper surface of the horizontal plate portion 43 b of the support plate 43. The rail 44 is formed in a C-shaped cross section.

  Specifically, the rail 44 includes a bottom plate 44a, a pair of vertical plates 44b extending upward from both end portions in the width direction (front-rear direction) of the bottom plate 44a, and an upper end of each vertical plate 44b in the width direction center of the bottom plate 44a. It is comprised by the horizontal plate 44c extended toward. The bottom plate 44a is fixed to the horizontal plate portion 43b by a plurality of bolts 48 and nuts 49 at predetermined intervals in the longitudinal direction (left and right direction). The base 21a of the packing 21 is inserted and fixed in a space surrounded by the bottom plate 44a, the pair of vertical plates 44b, and the pair of horizontal plates 44c.

  The vertical plate portion 43a of the support plate 43 is in contact with the front surface of the screen portion 41 and is separated by a plurality of (five in this case) bolts 45 and nuts 46 at predetermined intervals in the longitudinal direction (left and right direction). It is attached to 41. A plurality of (in this case, nine) bolt holes 43c for inserting the bolts 45 are formed in the vertical plate portion 43a at predetermined intervals in the left-right direction. Although illustration is abbreviate | omitted, as for these bolt holes 43c, all consist of round holes.

  FIG. 12 is a front view of the container main body 2 in which the illustration of the support portion 42 and the packing 21 is omitted. In FIG. 11 and FIG. 12, a plurality of bolt holes 411 through which the bolts 45 are inserted are formed in the screen portion 41 at predetermined intervals in the left-right direction. The plurality of bolt holes 411 are two round holes 411A formed on the outermost side (right and left end parts) in the left-right direction, and a predetermined hole formed vertically longer inside the left-right direction than the round holes 411A. It consists of a number (here nine) long holes 411B.

  The bolt 45 is inserted from the rear side of the screen part 41 through the washer 47 into the bolt hole 411 of the screen part 41 and the bolt hole 43 c of the support plate 43. A nut 46 is fastened to a portion of the support plate 43 of the bolt 45 which protrudes forward beyond the vertical plate portion 43 a.

With the above configuration, by loosening the fastening of the plurality of bolts 45 and the nuts 46, the bolts 45 inserted through the long holes 411B are vertically moved along the long holes 411B of the screen part 41. The position of the support portion 42 can be adjusted along with the packing 21 in the vertical direction.
Therefore, in the present embodiment, the support portion 41, the pair of support portions 42, and the plurality of bolts 48 and the nuts 49 support the packing 21 so as to be positionally adjustable in the vertical direction with respect to the peripheral portion of the opening A. The mechanism 40 is configured. The support mechanisms 40 are respectively provided on the front and rear of the container body (see FIG. 9).

  Thus, when the upper surface of the packing 21 is not arranged parallel to the back surface of the canopy 5 in the closed position due to a manufacturing error, the packing 21 is vertically moved relative to the peripheral portion of the opening A by the support mechanism 40. By adjusting the position, the upper surface of the packing 21 can be disposed parallel to the back surface of the canopy 5. As a result, it is possible to suppress the decrease in the sealing surface pressure between the canopy 5 and the packing 21 in the closed posture.

  In addition, the canopy 5 in the closed posture is disposed in a state in which the inner end in the left-right direction can be swung in the vertical direction around the support position of the guide roller 29 at the outer end in the left-right direction. For this reason, the closed posture of the canopy 5 is likely to cause individual differences in the swing amount in the vertical direction at the inner end in the horizontal direction due to a manufacturing error. However, even if such individual differences occur, when the plurality of bolts 48 and nuts 49 of the support mechanism 40 are loosened, the outer end portion of the support portion 42 is a bolt inserted into the round hole 411A of the screen portion 41. The position is fixed by 45. Therefore, with the outer end (bolt 45) of the support portion 42 as the center, that is, the upper end of the support portion 42 vertically about the support position side (the swing center side) of the canopy 5 in the closed posture. The position can be adjusted while swinging. Thus, position adjustment can be easily performed in which the upper surface of the packing 21 is disposed parallel to the back surface of the canopy 5.

[Left and right peripheral edge of opening]
FIG. 13 is a cross-sectional view taken along the line III-III in FIG. In FIG. 9 and FIG. 13, a screen 51 is erected on the upper surface of the container body 2 at the right and left peripheral edge of the opening A of the container body 2 (see also FIG. 10). Each partition 51 is made of a channel material extending in the front-rear direction. On the upper surface of the horizontal plate portion 51a formed at the upper end portion of each screen portion 51, a rubber packing as a "other direction seal" extending along the front-rear direction (the other direction) via a support portion 52 described later 23 are attached. The packing 23 shown in FIG. 9 is hatched for convenience of illustration.

  The packing 23 has the same cross-sectional shape as the packing 21 and has a base 23a attached to a rail 53 described later, and a main body 23b integrally formed on the upper part of the base 23a. The main body portion 23b is formed in a tubular shape, and has a hollow portion 23c inside. The back surface of the canopy 5 is in contact with the upper surface of the main body portion 23b. Thereby, the packing 23 seals between the canopy 5 in the closed position and the left and right peripheral edge portions of the opening A of the container body 2.

  A support 52 to which the packing 23 is attached is attached to the upper surface of the horizontal plate 51 a of each screen 51. The support portion 52 of the present embodiment is configured by the rail 53. The rails 53 are formed to extend in the front-rear direction along the entire length of the partition 51. Further, the rail 53 is formed in a C-shaped cross section which has the same cross sectional shape as the rail 44.

  Specifically, the rails 53 include a bottom plate 53a, a pair of vertical plates 53b extending upward from both end portions in the width direction (left and right direction) of the bottom plate 53a, and the top of each vertical plate 53b in the width direction center of the bottom plate 53a. It is comprised by the horizontal plate 53c extended toward. Although not shown, the bottom plate 53a is fixed to the horizontal plate portion 51a by a plurality of bolts 54 and nuts 55 at predetermined intervals in the longitudinal direction (front-rear direction). The base 23a of the packing 23 is inserted and fixed in a space surrounded by the bottom plate 53a, the pair of vertical plates 53b, and the pair of horizontal plates 53c.

  FIG. 14 is a perspective view showing the outer end of the rail 44 and the front end of the rail 53 with the packings 21 and 23 omitted. The longitudinal outer end (right end) of the rail 44 abuts on the front end of the rail 53. Specifically, the outer end surface 44 e in the longitudinal direction of the rail 44 is in contact with the left outer surface 53 e at the front end of the rail 53. Although not shown, the outer end in the longitudinal direction of the rail 44 disposed on the rear side of the opening A also abuts on the rear end of the rail 53. Thus, the longitudinal end of the packing 23 attached to the rail 53 can be disposed at a position close to the outer end of the packing 21 attached to the rail 44.

  The front end surface 53 d of the rail 53 is disposed to be substantially flush with the front side outer surface 44 d of the rail 44. The front end portions of the left vertical plate 53 b and the horizontal plate 53 c of the rail 53 are cut out along the entire length of the rail 44 in the width direction (front-rear direction). Thereby, the connection packing 25 (described later) disposed at the contact portion between the outer end of the rail 44 and the end in the longitudinal direction of the rail 53 can be easily attached across the rails 44 and 53.

[Connecting seal]
In FIG. 9, at each of the four corners of the peripheral edge of the opening A of the container body 2, a connection packing 25 as a “connection seal” for connecting the outer end of the packing 21 and the end in the longitudinal direction of the packing 23 is disposed. It is done. In addition, cross hatching is given to the connection packing 25 shown in FIG.9 and FIG.10 for convenience of illustration.

  FIG. 15 is an enlarged plan view of the connection packing 25 in the IV portion of FIG. FIG. 16 is a side view of the connection packing 25 of FIG. 15 as viewed from the rear side. In FIG. 16, the connection packing 25 has the same cross-sectional shape as the packings 21 and 23, and is integrally formed on the base 25 a attached to the contact portion with the rails 44 and 53 and the upper part of the base 25 a. And a main body 25b. The main body portion 25b is formed in a tubular shape, and has a hollow portion 25c inside. The corner of the back surface of the canopy 5 is in contact with the upper surface of the main body 25b. Thus, the connection packing 25 seals between the canopy 5 in the closed position and the corner of the peripheral edge of the opening A of the container body 2.

  In FIG. 15, the connection packing 25 is formed in an L shape in plan view, and one end 25 d to which the outer end of the packing 21 can be connected and the other end to which the longitudinal end of the packing 23 can be connected. And a part 25e.

  At the outer end portion of the packing 21, a first receiving port 21d having the same cross-sectional shape as the main body 21b (see also FIG. 11) is formed.
