Description

  The present invention relates to a cylindrical body movement prevention device. The cylindrical body is, for example, vinyl or other resin film or paper wound in a roll shape, or a duct having a circular cross section, and the present invention rolls when the cylindrical body is transported by being mounted on a vehicle or the like. It is suitable for preventing movement such as slippage and preventing collapse of cargo.

  When cylinders are stacked horizontally on a cargo bed of a vehicle such as a truck, or on a pallet mounted on the cargo bed, it is necessary to prevent movement in the horizontal plane such as rolling and shifting during transportation to prevent collapse of the cargo. It is. In the past, this was often done by driving a wooden wedge between the cylinder and the loading platform or pallet. However, there is a possibility that the wedge may come off due to vibration during transportation, and the movement cannot always be effectively prevented.

On the other hand, Patent Document 1 discloses a configuration in which a member having a semicircular cross section is combined, and a cylindrical body (roll-like object) is accommodated in a circular cross section space formed by the opposing recess. . According to the configuration disclosed in Patent Document 1, since the roll-shaped object is stored in a space having a circular cross-section, an effect is obtained that the movement is prevented and the collapse of the load is difficult.
JP-A-9-12031

  However, since the member disclosed in Patent Document 1 forms a space for accommodating the cylindrical body, the size of the member must be increased accordingly. In view of the fact that some cylinders have various diameters, a member must be prepared for each cylinder having a different diameter. Further, considering the work at the time of loading, after installing one member, a procedure is required in which the cylindrical body is placed in the concave portion and another member is covered. Also, the reverse work procedure is required when unloading. That is, a complicated procedure is required for loading and unloading operations.

  The present invention has been made in view of the above, and an object thereof is to effectively prevent the movement of a cylindrical body without fear of dropping off due to vibration.

  Another object of the present invention is to provide a cylindrical body movement prevention device that can be reduced in size and improve workability during loading and unloading.

  Still another object of the present invention is to provide a movement prevention device that is easy to operate and can be handled safely.

  Another object of the present invention is to provide a movement preventing device that is excellent in storage property when not in use.

  For this purpose, the cylindrical body movement preventing device according to the present invention is provided with a support portion having a support surface that contacts the side surface of the cylinder body in an inclined state, a base that holds the support portion, and the support portion. A stopper for maintaining the tilted state of the support part by engaging, and a lock attached to the base and a position for maintaining the tilted state of the support part by engaging with the stopper. A lock mechanism capable of releasing the lock in accordance with an operation from the back side of the surface, and the base has the support surface facing upward and downward in the unlocked state. The support part is foldably held in a state.

  According to the present invention, while the base is fixed to a pallet or the like, the support surface is brought into contact with the cylindrical body in a state in which the support portion is inclined, thereby effectively preventing the movement of the cylindrical body without fear of dropping off due to vibration. . In addition, by making the support portion foldable in any direction on the base, it is possible to improve the workability during loading / unloading while reducing the size and also improve the storage property when not in use. Further, when handling the movement prevention device, the operator only needs to perform an operation on the back side of the support surface, that is, the back side of the surface facing the cylindrical body, so that the operation can be easily and safely performed.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a movement preventing apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view of the right side surface of FIG. Hereinafter, for the sake of convenience, the side facing the cylinder is referred to as the front side, and the side facing the operator on the back side is referred to as the back side.

  In these drawings, reference numeral 10 denotes a support portion, which has a support surface 12 with which a side surface of a cylindrical body 100 (shown by a two-dot chain line in FIG. 2) abuts. In order to prevent the cylindrical body 100 from being damaged, an elastic member such as rubber may be attached to the support surface 12. Guides 20 are attached to both sides of the support portion 10. One side edge of the guide 20 is a curved portion, and a guide groove 24 having a shape along the curved portion is provided. Reference numeral 30 denotes a base having a pair of opposing side walls 32. A pin 34 is erected inward on the side wall 32 and is fitted into the guide groove 24. Accordingly, the guide 20 or the support portion 10 can be displaced with respect to the base 30 by the pin 34 relatively moving in the guide groove 24. 26 is a member that reinforces the guide 20 around the portion of the guide groove 24 into which the pin 34 fits in the state shown in FIGS. 1 and 2 for supporting the cylindrical body.

  A pair of stays 14 project from a substantially central portion of the back surface of the support portion 10, and a shaft 16 having a circular cross section is fixed between the stays. The support end of the stopper 40 is loosely fitted to the shaft 16. The distal end 42 of the stopper 40 can be inserted into a hole 38 provided in the bottom surface of the base 30. In the inserted state shown in the figure, the shoulder 44 near the tip 42 of the stopper 40 abuts on the bottom surface of the base 30, and the middle shoulder 46 of the stopper 40 abuts on the upper edge of the back plate 33 of the base 30. This prevents the stopper 40 from rotating. At the same time, the cylindrical body 100 can be supported by locking the support portion 10 via the shaft 16. The stopper 40 is provided with an engaging portion 48 that engages with the lock portion 52 in the inserted state, thereby preventing the stopper 40 from being detached from the hole 38. Further, a taper 42A is formed at the tip 42 of the stopper 40 so that the insertion into the hole 38 is performed smoothly.

  FIG. 3 is a perspective view showing the lock mechanism 50 including the lock portion 52. What is indicated by reference numeral 60 is a pair of left and right holding portions, and receives the stopper 40 in the gap between them, and the lock portion 52 (FIG. 2) is located. Reference numeral 54 denotes an operation unit, a part of which is a lock unit located in the gap formed by the pair of holding units 60. The lock unit 52 or the operation unit 54 can rotate in a space formed by the back plate 33 of the base 30 and the recess 62 of the holding unit 60. The operation portion 54 is biased by a spring 56 to a position (lock position) where the lock portion 52 engages with the engagement portion 48 of the stopper 40 shown in FIG. Further, the position where the lock part 52 is disengaged from the engaging part 48 of the stopper against the biasing force of the spring 56 in accordance with the pressing or pressing operation (direction indicated by the arrow in FIG. 3) of the operator from the back side. Swinging to the (unlock position) is possible.

  In addition, what is shown with the code | symbol 70 in FIG. 1 is an attaching part to the pallet etc. which are not shown in figure, and has a channel shape. The movement preventing device of the present embodiment is slidably attached to a pallet having an opening having a width substantially matching the outer dimension between the left and right side walls 32. At this time, the attachment portion 70 is fixed to the bottom surface of the base 30 with bolts or the like with the support guide portion on the pallet side inserted through the inside of the channel. A plurality of holes are provided in the support guide portion on the pallet side, and the tip end portion of the stopper 40 enters the hole at an appropriate position through the hole 38, so that the outer diameter of the cylindrical body can be adjusted. Thus, the movement preventing device can be positioned and fixed. Of course, the shape of the attachment portion 70 can be determined as appropriate according to the pallet to be attached. Then, an appropriate number of movement preventing devices can be set at a predetermined position in the longitudinal direction of the cylindrical body and at a position corresponding to the dimension (diameter) of the cylindrical body, and the attachment portion 70 can be fixed to a pallet or the like. As a result, the movement preventing device is fixed, and the movement of the cylindrical body can be effectively prevented without dropping due to vibration during transportation.

  The operation of the cylindrical body movement preventing apparatus having the above configuration will be described.

FIG. 4 shows a state immediately before the support unit 10 is set to a position where the cylindrical body shown in FIG. 2 is supported, or just after the support unit 10 is lifted from this state.
When the support portion 10 is set at the cylindrical body support position from this state, the support portion 10 may be lowered as it is while supporting the bent portion 10A with a hand. The stopper 40 loosely fitted to the shaft 16 at the support end is suspended vertically downward according to the action of gravity, and the tip end portion 42 faces the hole 38. At this time, even if there is a slight misalignment, the tip 42 is guided into the hole 38 by the taper 42A. Moreover, since the side edge part of the stopper 40 engages with the lock part 52, and this becomes a cam surface and deviates the lock part 52 toward the lock release position, the downward movement is performed smoothly. When the distal end portion 42 is completely inserted into the hole 38 and the lock portion 52 faces the engagement portion 48 of the stopper, the lock portion 52 is rotated to the lock position according to the urging force of the spring 56. On the other hand, when the stopper 40 is removed from the hole 38, the operating portion 54 is operated to set the lock portion 52 to the unlock position, and then the support portion 10 is lifted upward.

  When performing these operations, the operator mostly performs operations on the back side of the base back plate 33. This is because the bent portion 10A touched by the operator is located on the back side of the base back plate 33 except in the folded state described below. The operator's finger enters the front side of the bent portion back plate 33 only when the operation unit 54 is pressed in the direction of the arrow shown in FIG. 3 to release the locked state.

  Next, an operation when the support portion 10 is folded on the base will be described. In the present embodiment, the support surface 12 can be folded on the bottom surface of the base 30 with the support surface 12 facing upward or downward.

  5 to 7 are perspective side views for explaining an operation when the support surface 12 is folded with the support surface 12 facing upward.

  After further lifting the support portion 10 from the state shown in FIG. 4, first, the support portion 10 is inclined toward the back side as shown in FIG. At this time, the stopper 40 can be inclined with a finger or the like so that the tip 42 of the stopper 40 does not interfere with the bottom surface of the base 30. When the support portion 10 is pushed in the front direction from this state, the pin 34 of the base side wall 32 guides the support portion 10 while relatively sliding along the guide groove 24 as shown in FIG. It will be in a folded state.

  Here, the guide groove 24 has a curved shape. Therefore, in the process of reaching the state of FIG. 7, the support part 10 moves so as to draw an arc. At this time, since the side edge portion of the guide 20 also has a curved shape, interference with the back plate 33 and the bottom surface of the base 30 does not occur. This is also one of the features of the present embodiment. For example, when loading and unloading the cylindrical body, if the cylindrical body is slightly lifted by a crane, a forklift, or the like, the support portion 10 is inserted so as to sink under it. This is because it can be moved and folded. In the folded state shown in FIG. 7, since the support surface 12 is substantially horizontal, the cylindrical body can be lowered by rolling the support surface 12 or the like.

  Further, when the support portion 10 is folded for such unloading, the operator's finger enters the front side of the back plate 33 as described above by pressing the operation portion 54 and the stopper 40. It is only a moment of releasing the locked state and does not enter the support surface 12 side. Therefore, even if the cylinder falls from a forklift or the like, the risk of injury is extremely reduced. This is also one of the features of this embodiment.

  In addition, if it is desired to set the support portion 10 at the cylindrical body support position after loading, an operation reverse to that performed when unloading may be performed.

  8 and 9 are perspective side views for explaining the operation when the support surface 12 is folded with the support surface 12 facing downward. After further lifting the support portion 10 from the state shown in FIG. 4, the support portion 10 is inclined toward the front side as shown in FIG. If this is tilted toward the front side as it is, a folded state as shown in FIG. 9 is obtained.

  As described above, it is also one of the features of the present embodiment that the support portion 10 can be folded on the bottom surface of the base 30 with the support surface 12 facing upward or downward. This is because, when the movement preventing device is not used or stored, the operator does not pay particular attention to the folding direction, that is, the operator can easily fold it by a method that is easy to operate.

In the above embodiment, the locked state of the stopper 40 is released by pressing or pressing the operating unit 54 from the back side of the back plate 33. However, the configuration of the operating unit for releasing the locked state Of course, can be determined as appropriate.
FIG. 10 shows another embodiment of the lock mechanism. In this example, the operation end portion 54A of the operation portion 54 is bent in a direction opposite to that in FIG. The operator can release the locked state of the stopper 40 by pulling up the operation end 54A in the direction indicated by the arrow in the drawing to rotate the operation portion 54 in the same manner as described above. By configuring the operation portion 54 as in this embodiment, the direction of the force applied to the operation end portion 54A for releasing the locked state and the force applied to the bent portion 10A to lift the support portion 10 when the support portion 10 is folded. Will match the direction of. Therefore, at this time, the operator only has to hold the operation end portion 54A and the bent portion 10A with one hand at the same time and perform a one-action pull-up operation, so that the operation can be performed extremely simply and quickly. Safety is further improved.
