Description

  The present invention relates to a fork cover used by being mounted on a fork of a forklift.

  Conventionally, in a physical distribution environment in a warehouse or the like, an object to be transported is transported using a forklift. At that time, the conveyed object is placed on a flat plate called a pallet that can be attached to and detached from the fork of the forklift. The forklift is used to store, transport, store, and unload the object to be transported. In addition, when carrying out cargo handling and picking work by hand at a high place, the cab is lifted and lowered together with the fork, and the forklift that allows the driver to perform cargo handling work and picking work in the raised and lowered state Is used (see Patent Document 1).

  On the other hand, in recent physical distribution sites, products and packages to be transported are becoming smaller. And when warehousing the goods to be transported in the small mouth, after receiving the goods with a transporting carriage called a carriage, it is transferred onto a pallet and transported by a forklift configured so that the cab is raised and lowered together with the fork. Etc. are stored. In addition, when unloading a small object to be transported, after sorting and picking from a stored warehouse etc. and transporting it with a forklift configured so that the cab is raised and lowered together with the fork, it is transferred from the pallet to the cart. Work is done.

  However, since the objects to be transported are different in size, the amount to be loaded on the pallet has been limited. In addition, when loading and unloading the object to be transported, an operation of reloading between the pallet and the cart occurs, which takes time. Furthermore, since the operation of the forklift can be performed only by qualified personnel, only a limited number of people can work. As described above, with the reduction in the size of the object to be transported, there has been a problem that cargo handling and picking work cannot be performed efficiently.

[Fork cover]
First, the fork cover 10 according to the present embodiment will be described with reference to FIGS. 1A to 1C. As shown in FIGS. 1A to 1C, the fork cover 10 according to the present embodiment is a pair of cylindrical members 11, 11 and a flat plate-like member fixed across the pair of cylindrical members 11, 11. A floor member 12, a base side carriage fixing member 13 fixed to the pair of cylinder members 11, 11 in a perpendicular direction across the pair of cylinder members 11, 11, and a pair of cylinders for each of the pair of cylinder members 11, 11 And a front end side carriage fixing member 14 fixed to the members 11 and 11 in the vertical direction. The base side carriage fixing member 13 is provided on the base side (fork lift 50 side described later) of the pair of forks 55 attached to the pair of cylindrical members 11, 11. Further, the tip side carriage fixing member 14 is provided on the tip side of the pair of forks 55 attached to the pair of cylinder members 11, 11 (the side opposite to the forklift 50).

  1A to 1C, the front end side of the pair of forks 55 attached to the fork cover 10 is the left side of the drawing, and the base side of the pair of forks 55 attached to the fork cover 10 is the right side of the drawing. Further, the longitudinal direction, the width direction, and the vertical direction of the pair of forks 55 to be mounted are as shown in FIGS. 1A to 1C, and in the following description of the fork cover 10, the longitudinal direction of the pair of forks 55 to be mounted Is the “longitudinal direction” of the fork cover 10, the width direction of the pair of forks 55 to be mounted is the “width direction” of the fork cover 10, and the vertical direction of the pair of forks 55 is the “vertical direction of the fork cover 10. "

  As shown in FIG. 1C, the pair of cylindrical members 11 and 11 have a rectangular cross section and include an opening 11 a that allows a pair of forks 55 (see FIG. 2) of a forklift 50 described later to be attached and detached. The opening 11a is provided at the end on the base side of the pair of forks 55 attached to the pair of cylindrical members 11. Note that the ends on the front end side of the pair of forks 55 attached to the pair of cylinder members 11 are configured to have an opening 11c. Note that, in the fork cover 10 according to the present embodiment, as described later, the openings 11c are not opened because the ends of the pair of forks 55 are not configured to be inserted and protrude from the pair of cylindrical members 11. The closed portion 11c may be closed. Then, the pair of forks 55 is inserted from the openings 11 a of the pair of cylinder members 11.

  The pair of cylindrical members 11 is formed to be the same as the length of the horizontal piece of the pair of forks 55 or slightly longer than the length of the horizontal piece of the fork 55. Here, the length of the horizontal piece of the pair of forks 55 means a length extending from a cab 53 of a forklift 50 described later. Further, the pair of cylindrical members 11 are formed such that the width of the inner peripheral surface of the opening 11a is such that the pair of forks 55 and the pair of lock mechanisms 56 provided inside the pair of forks 55 can be inserted respectively. (See FIG. 2B) and the outer width W1 is formed to be substantially constant. Further, the pair of cylindrical members 11 has an inner space that is thicker than the pair of forks 55 and has a bottom surface that does not contact the ground when mounted on the fork 55 at the lowest position. Formed with thickness. As described above, the pair of cylindrical members 11 are detachably mounted from the distal ends of the pair of forks 55 to the base. The pair of cylindrical members 11 are formed by, for example, bending a steel plate or extruding a steel material.

  Here, as shown in FIG. 1B, the pair of cylindrical members 11 are provided with inclined portions 11 b at an angle in which the bottom faces upward from the base side to the tip side of the pair of forks 55 to be mounted. It is preferable. That is, the pair of cylindrical members 11 are provided with the inclined portions 11b on the bottom surfaces so that the thickness thereof becomes thinner toward the distal end side of the pair of forks 55 to which the pair of cylindrical members 11 are attached. When the forklift 50 fitted with the fork cover 10 is operated by the inclined portion 11b and a pair of forks 55 is inserted below the carriage 20 described later (see FIG. 3), the fork cover 10 comes into contact with the ground. This can be prevented. However, the inclined portion 11b is formed so that the inner peripheral surfaces of the pair of cylindrical members 11 are thicker than the thickness of the fork 55 to be mounted. This is because the pair of forks 55 is inserted from the tip to the base.

  Furthermore, it is preferable that a friction material is provided on the inner peripheral surfaces of the pair of cylindrical members 11 on the surfaces that come into contact with the pair of forks 55. The friction material is a plate-shaped friction material made of, for example, rubber, resin, or the like, and is bonded to the upper part (in particular, near the opening 11a) of the inner peripheral surfaces of the pair of cylindrical members 11. Alternatively, a friction material may be provided on the upper surfaces of the pair of forks 55. Thereby, it is possible to prevent the fork cover 10 from being displaced or removed from the pair of forks 55.

  Further, as shown in FIGS. 1A to 1C, the pair of cylindrical members 11 are respectively provided at the end portions on the base side of the pair of forks 55 to be mounted, and abutment portions that abut on an operation platform 53 of a forklift 50 described later. It is preferable to provide the stopper 15 provided with 15b. The stopper 15 is fixed to the upper surfaces of the pair of cylinder members 11 so that the contact portions 15b are perpendicular to the upper surfaces of the pair of cylinder members 11.

  The stopper 15 is formed, for example, by bending a plate-like member having the same width as the width W1 of the pair of cylindrical members 11 formed of a steel plate at a right angle. That is, the stopper 15 is processed so that the cross section in the longitudinal direction has an L shape. The stopper 15 includes a contact portion 15b that contacts the cab 53 and a fixing portion 15c that is fixed to the pair of cylindrical members 11 with the bent portion 15a interposed therebetween. The stopper 15 is arranged perpendicular to the pair of cylindrical members 11 so that the contact portion 15b is positioned at the tip of the pair of cylindrical members 11, and the fixing portion 15c is fixed to the pair of cylindrical members 11 by welding or the like. The

  The contact portion 15 b of the stopper 15 is so high that it does not enter the gap between the cab 53 and the pair of forks 55 when the butt 53 abuts against the cab 53, and protrudes from the cab 53. It is formed at a height that does not. When the height of the contact portion 15 b of the stopper 15 is lower than the height that does not enter the gap between the cab 53 and the pair of forks 55, the pair of cylinder members 11 of the fork cover 10 are placed under the forklift 50. This is because they get in and hit the wheels of the forklift 50 or damage the forklift 50. Further, if the height of the contact portion 15 b of the stopper 15 is a height protruding from the cab 53, the driver may get caught in the stopper 15 when moving to the floor member 12. When the fork cover 10 is mounted on the fork 55 of the forklift 50, the stopper 15 comes into contact with the driver's cab 53 as shown in FIG. 2A.

  As shown in FIG. 1A, the floor member 12 is formed in a rectangular flat plate shape and is provided adjacent to the stopper 15 on the base side of a pair of forks 55 to be mounted. The floor member 12 is formed of a flat steel plate or the like, and is fixed to the upper surfaces of the pair of cylinder members 11 by welding or the like across the pair of cylinder members 11. The floor member 12 is preferably formed with a thickness that allows the driver to get on and work. Here, the floor member 12 is preferably formed such that the width W2 thereof is longer than the width W3 of both ends of the pair of cylindrical members 11. Furthermore, it is more preferable that the width W2 of the floor member 12 is approximately the same as the width W4 of the cab 53 of the forklift 50 facing the floor member 12 (see FIG. 6). Further, the floor member 12 is formed with a length that does not cause a gap between the stopper 15 and a base-side carriage fixing member 13 described later. By configuring in this way, the driver's footing is secured, and when the driver moves from the cab 53 to the floor member 12, the driver's foot is prevented from being stepped off to ensure work safety. Can do.

  Moreover, it is preferable that a friction material or a protrusion is provided on the upper surface of the floor member 12 as a slip stopper when the driver works.

  As shown in FIGS. 1B and 1C, a pair of floor support members 12 </ b> A and a pair of floor support members 12 </ b> B disposed on the lower surface of the floor member 12 so as to contact the outer side surfaces of the pair of cylinder members 11, respectively.

That is, the pair of floor support members 12A and 12B are processed so that the cross section in the longitudinal direction has an L shape. The pair of floor support members 12A and 12B includes support portions 12bA and 12bB arranged perpendicular to the lower surface of the floor member 12 with the bent portions 12aA and 12aB interposed therebetween, and fixing portions 12cA and 12cB fixed to the floor member 12. Consists of.

  Here, each of the pair of floor support members 12A and 12B is formed to have substantially the same length W5 from the end in the width direction of the floor member 12 to the outer side surface of the pair of cylindrical members 11. . The pair of floor support members 12A are arranged such that the support portion 12bA is positioned on the front end side of the fork 55 on the lower surface of the floor member 12 and parallel to the width direction of the floor member 12, and the fixing portion 12cA is disposed on the floor. It is fixed to the member 12 by welding or the like. The pair of floor support members 12B are arranged such that the support portion 12bB is located on the base side of the fork 55 on the lower surface of the floor member 12 and is parallel to the width direction of the floor member 12, and the fixing portion 12cB is disposed on the floor. It is fixed to the member 12 by welding or the like.

  Furthermore, the end portions of the pair of floor support members 12A and 12B that are in contact with the outer side surfaces of the pair of cylindrical members 11 are preferably fixed to the outer side surfaces of the pair of cylindrical members 11 by welding or the like. The floor member 12 is firmly fixed to the pair of cylinder members 11 by the pair of floor support members 12A and 12B, and the strength of the end portions of the floor member 12 outside the pair of cylinder members 11 is improved. Safety can be ensured.

  Note that the pair of floor support members 12 </ b> A and 12 </ b> B may be further arranged so as to contact the inner side surfaces of the pair of cylindrical members 11. As a result, the floor member 12 can be more firmly fixed to the pair of cylinder members 11, and the strength inside the pair of cylinder members 11 of the floor member 12 can be improved to ensure work safety.

  Moreover, although a pair of floor support members 12A and 12B are arrange | positioned in the front end side and base part side of the fork 55 in the lower surface of the floor member 12, it is not restricted to it. The pair of floor support members 12 a and 12 b may be disposed at the center between the front end side and the base side of the fork 55 on the lower surface of the floor member 12. As a result, the floor member 12 is more firmly fixed to the pair of cylinder members 11 and the strength of the end portions of the floor member 12 outside the pair of cylinder members 11 is further improved to ensure work safety. be able to.

  The base side carriage fixing member 13 is provided adjacent to the floor member 12 on the distal end side of the fork 55, and is fixed across the pair of cylinder members 11. The base side carriage fixing member 13 is formed by bending a plate-like member made of, for example, a steel plate at a right angle. That is, the base side cart fixing member 13 is processed so that the cross section in the longitudinal direction has an L shape. The base-side carriage fixing member 13 includes an opposing portion 13b that is disposed perpendicularly to the pair of cylindrical members 11 and a fixing portion 13c that is fixed to the upper surfaces of the pair of cylindrical members 11 with the bent portion 13a interposed therebetween. . That is, the base-side carriage fixing member 13 is fixed to the upper surfaces of the pair of cylinder members 11 so that the contact portions 13b are perpendicular to the upper surfaces of the pair of cylinder members 11. The facing portion 13 b faces one side surface in the longitudinal direction of the fork cover 10 of the carriage 20 (see FIGS. 6A and 6B) placed on the upper surfaces of the pair of cylindrical members 11. 6A and 6B show the main parts of the fork cover 10 and the carriage 20 according to the embodiment of the present invention in a state where the carriage 20 is placed. FIG. 6A is a perspective view showing the main parts (the floor member 12 and the base-side carriage fixing member 13) of the forklift 50, the carriage 20, and the fork cover 10. FIG. 6B is a front view showing the main part (the tip side truck fixing member 14) of the truck 20 and the fork cover 10. In FIG. 6B, the forklift 50 to which the fork cover 10 is attached is not shown.

  Here, the base-side carriage fixing member 13 is formed so that the width thereof is the same as the width W3 of both end portions of the pair of cylindrical members 11. The base-side carriage fixing member 13 is disposed so that the facing portion 13b is positioned on the tip side of the fork 55 and parallel to the width direction, and the fixing portion 13c is welded to the upper surfaces of the pair of cylindrical members 11 by welding or the like. It is fixed.

  The base-side carriage fixing member 13 is formed such that the height H1 of the facing portion 13b is lower than the height of the facing portion of the facing carriage 20. In the fork cover 10 according to the present embodiment, the facing portion of the carriage 20 that faces the facing portion 13 b is a caster frame 25. Therefore, in the fork cover 10 according to the present embodiment, as shown in FIGS. 6A and 6B, the height H1 of the facing portion 13b of the base-side carriage fixing member 13 is the height H3 of the caster frame 25 of the facing carriage 20. It is formed to be lower. When the height H1 of the facing portion 13b of the base-side carriage fixing member 13 is higher than the height of the facing portion, the portion that is above the facing portion (in this embodiment, the loading platform 21, the conveyed object, etc.) This is because there is a possibility that the base 20 will be caught on the tip of the facing portion 13b of the base-side cart fixing member 13 and the cart 20 cannot be placed on the upper surfaces of the pair of cylindrical members 11. And it can prevent the loading platform 21 being caught on the front-end | tip part of the opposing part 13b of the base side trolley | bogie fixing member 13. FIG.

  Further, as shown in FIG. 7, the base-side carriage fixing member 13 is formed by bending the tip portion 13bA of the facing portion 13b to the floor member 12 side (that is, the base side of the pair of forks 55). preferable. The carriage 20 is placed on the fork cover 10, that is, on the upper surface of the pair of cylindrical members 11 between the facing portion 13b provided in the base-side carriage fixing member 13 and the opposing portion 14b provided in the distal-side carriage fixing member 14 described later. In this case, the cart 20 can be guided to an appropriate position on the upper surface of the pair of cylindrical members 11 between the base-side cart fixing member 13 and the tip-side cart fixing member 14 by the bent tip portion 13bA. It is.

  The pair of distal end side truck fixing members 14 are provided on the distal end side of the pair of forks 55 and are fixed to the respective distal ends of the pair of cylindrical members 11. The distal-side carriage fixing member 14 is formed by bending a plate-like member made of, for example, a steel plate at a right angle. That is, the tip side trolley fixing member 14 is processed so as to have an L-shaped cross section. The distal-side trolley fixing member 14 is fixed to the distal end of the pair of cylindrical members 11 and the opposed portion 14b that is disposed perpendicularly to the pair of cylindrical members 11 and faces the other side surface of the trolley 20 across the bent portion 14a.

In other words, the tip-side carriage fixing member 14 is fixed to the upper surfaces of the pair of cylinder members 11 such that the contact portion 14 b is perpendicular to the upper surfaces of the pair of cylinder members 11.

  Here, the front end side cart fixing member 14 is formed so that the width thereof is the same as the width W <b> 1 of the pair of cylindrical members 11. The distal-side carriage fixing member 14 is disposed so that the facing portion 14b is located on the base side of the fork 55 and is parallel to the width direction, and the fixing portion 14c is welded to the upper surfaces of the pair of cylindrical members 11, respectively. It is fixed by.

  When the pair of forks 55 to which the fork cover 10 is attached is inserted into the tip side trolley fixing member 14, the height H2 of the facing portion 14b contacts the trolley 20 to be placed on the upper surfaces of the pair of cylindrical members 11. It is formed so that it is not so high. This is because the tip side carriage fixing member 14 is caught by the carriage 20 placed on the upper surfaces of the pair of cylinder members 11, and the pair of forks 55 with the fork cover 10 attached to the lower part of the carriage 20 cannot be inserted.

  Furthermore, it is preferable that the height H <b> 2 of the facing portion 14 b of the distal end side cart fixing member 14 is formed to be lower than the height of the facing portion of the facing cart 20. In the fork cover 10 according to the present embodiment, the facing portion of the carriage 20 that faces the facing portion 14 b is a caster frame 25. Therefore, in the fork cover 10 according to the present embodiment, as shown in FIG. 6B, the height H2 of the facing portion 14b of the distal end side carriage fixing member 14 is lower than the height H3 of the caster frame 25 of the facing carriage 20. Formed as follows. When the height H2 of the facing portion 14b of the distal-side carriage fixing member 14 becomes higher than the height of the facing portion, a portion above the facing portion (in this embodiment, the loading platform 21 or the object to be transported). This is because the carriage 20 is caught on the distal end portion of the facing portion 14 b of the distal end side carriage fixing member 14 and the carriage 20 cannot be placed on the upper surfaces of the pair of cylindrical members 11.

  Although not shown in the drawings, the distal end side cart fixing member 14 may be formed by bending the distal end portion of the facing portion 14 b toward the distal end sides of the pair of forks 55. When the carriage 20 is placed on the fork cover 10, that is, on the upper surface of the pair of cylindrical members 11 between the facing portion 13 b provided in the base-side carriage fixing member 13 and the opposing portion 14 b provided in the distal-side carriage fixing member 14. Moreover, it is because the cart 20 can be guided to an appropriate position between the base-side cart fixing member 13 and the tip-side cart fixing member 14 by the bent tip portion. However, when the height H2 of the facing portion 14b does not have a sufficient height, the tip portion does not have to be bent.

  In addition, the base side cart fixing member 13 and the tip side cart fixing member 14 include a pair of cylindrical members 11 between a facing portion 13 b provided in the base side cart fixing member 13 and a facing portion 14 b provided in the tip side cart fixing member 14.
