Description

[Technical Field]

[0001] The present disclosure relates to a stopper device for stopping a forklift. [Background technology]

[0002] Conventionally, stopper devices for stopping a forklift at an appropriate position are known (see, for example, Patent Document 1). The stopper device of Patent Document 1 stops the forklift at an appropriate position by having the wheels of the forklift hit the wheel chocks. The stopper device of Patent Document 1 adjusts the position at which the forklift is stopped by having the wheel chocks slide. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-293438 Summary of the Invention [Problem to be solved by the invention]

[0004] In the stopper device of Patent Document 1, the wheels of the forklift may ride up onto the wheel chocks, which may cause the forklift of Patent Document 1 to stop at a position that is different from the appropriate stopping position.

[0005] An object of the present disclosure is to provide a stopper device that can more reliably stop a forklift. [Means for solving the problem]

[0006] The stopper device according to the present disclosure is a stopper device for stopping a forklift, and includes a first stopper arranged at a position where it can come into contact with a mast of the forklift, a second stopper arranged at a position below the first stopper and protruding further than the first stopper, and a connecting member connecting the first stopper and the second stopper. [Effects of the Invention]

[0007] With this stopper device, the wheels of the forklift come into contact with the second stopper. The second stopper is pushed downward by the wheels and becomes sandwiched between the ground and the wheels. This locks the second stopper. When the second stopper is locked, the first stopper, which is connected to the second stopper via the connecting member, is also locked. This locks the vertical and horizontal positions of the first stopper. Therefore, the first stopper is locked in a position where it overlaps with the mast of the forklift in the vertical direction. As a result, a stopper device can be provided that can more reliably stop a forklift. [Brief explanation of the drawings]

[Figure 4] FIG. 2 is a diagram illustrating a stopped state of a forklift according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0009] An embodiment of the present disclosure will be described below with reference to the drawings. In the following description and drawings, the direction in which luggage is transported by the loading platform C1 is referred to as the transport direction Z, the front side in the transport direction Z is referred to as F, the rear side is referred to as B, the right side in the transport direction Z is referred to as R, the left side in the transport direction Z is referred to as L, the upper side is referred to as U, and the lower side is referred to as D.

[0010] As shown in FIG. 1, the stopper device 1 is a device for stopping a forklift X (see FIG. 4) so ​​that the forklift X does not collide with a loading platform C1. In the following description, an example will be described in which the loading platform C1 is a conveying device. Specifically, the loading platform C1 is a roller conveyor-type conveying device in which a plurality of conveying rollers C2, each having a rotation axis in the left-right direction, are arranged in the conveying direction Z. The forklift X removes a load sent from the front side F to the rear side B in the conveying direction Z at the position of the stopper device 1.

[0011] Furthermore, the loading platform C1 of this embodiment is movable in the left-right direction. Specifically, the loading platform C1 has two rails C3 extending in the left-right direction. The loading platform C1 moves left-right along the rails C3 in accordance with the left-right width of the cargo. Therefore, the stopper device 1 needs to stop the forklift X in accordance with the position of the moved loading platform C1. The loading platform C1 may be moved by an actuator such as an air cylinder, or by other means (for example, manual power).

[0012] The stopper device 1 is fixed to the loading platform C1. The stopper device 1 is movable together with the loading platform C1. In this embodiment, two stopper devices 1 are arranged side by side in the conveying direction Z.

[0013] As shown in FIGS. 2 and 3, the stopper device 1 includes a first stopper 2, a second stopper 4, a connecting member 6, a restricting member 8, an absorbing member 10, and a supporting member 12. As shown in FIG.

[0014] As shown in Fig. 4, the first stopper 2 is disposed at a position where it can come into contact with the mast X1 of the forklift X. Specifically, the first stopper 2 is disposed at a position where it overlaps with the mast X1 of the forklift X in the left-right direction. As shown in Fig. 2, in this embodiment, the first stopper 2 is a rod-shaped metal member having a substantially rectangular cross section that extends in the conveying direction Z.

[0015] As shown in FIG. 3, the first stopper 2 is supported by the support member 12 so as to be movable in a direction away from the loading platform C1 (see FIG. 1) (to the right in this embodiment) or in a direction toward the loading platform C1 (to the left in this embodiment). In this embodiment, a plate-shaped roller receiving member 21 extending in the conveying direction Z is fixed to the first stopper 2. A cylindrical slide rod 22 is fixed to the roller receiving member 21. The slide rod 22 is held by the absorbing member 10 so as to be movable in the left-right direction. In the following description, the direction away from the loading platform C1 or the direction toward the loading platform C1 may also be referred to as the movement direction of the first stopper 2.

[0016] The second stopper 4 is disposed below the first stopper 2 and at a position farther from the loading platform C1 (see FIG. 1) in the left-right direction than the first stopper 2. In this embodiment, the second stopper 4 is disposed to the right of the first stopper 2. The second stopper 4 is a member extending parallel to the first stopper 2. At least one side of the second stopper 4 extends parallel to the ground G (see FIG. 4). In this embodiment, the second stopper 4 is a rod-shaped metal member with a substantially rectangular cross section that extends in the conveying direction Z, and the bottom surface of the second stopper 4 extends parallel to the ground G.

[0017] As shown in FIGS. 2 and 3 , the connecting member 6 connects the first stopper 2 and the second stopper 4. In this embodiment, the connecting member 6 connects both ends of the first stopper 2 and the second stopper 4 in the conveying direction Z. As shown in FIG. 2 , the connecting member 6 has a first member 61, a second member 62, and a fixing member 63. The first member 61 is fixed to both ends of the first stopper 2 in the conveying direction Z. The first member 61 is a metal member having a substantially U-shaped cross section with an opening capable of accommodating the second member 62 facing rightward. The second member 62 is a plate-like metal member fixed to the second stopper 4 and extending in the left-right direction. The fixing member 63 is an L-shaped plate-like metal member having a first surface 63a extending in the left-right direction and a second surface 63b extending in the up-down direction.

[0018] The connecting member 6 has a first adjustment mechanism 64 and a second adjustment mechanism 65. The first adjustment mechanism 64 can adjust the vertical position of the second stopper 4 relative to the first stopper 2. In this embodiment, the first adjustment mechanism 64 is an elongated through-hole provided in the second surface 63b of the fixing member 63 and a bolt inserted through the through-hole. The fixing member 63 is fixed to the fixing member 63 by screwing the bolt into a screw groove provided in the bottom surface of the U-shaped first member 61. The first adjustment mechanism 64 can adjust the vertical position of the second stopper 4 relative to the first stopper 2 by changing the position of the bolt. In this embodiment, two through-holes are provided side by side in the conveying direction Z.

[0019] The second adjustment mechanism 65 can adjust the distance of the second stopper 4 relative to the first stopper 2 in the direction (left-right direction in this embodiment) in which it moves away from the loading platform C1 (see FIG. 1). In this embodiment, the second adjustment mechanism 65 is an elongated through-hole provided in the first surface 63a of the fixing member 63 and a bolt inserted through the through-hole. The fixing member 63 is fixed to the fixing member 63 by threading the bolt into a screw groove provided in the upper surface of the second member 62. The second adjustment mechanism 65 can adjust the left-right position of the second member 62 by changing the position of the bolt. In this way, the second adjustment mechanism 65 can adjust the left-right position of the second stopper 4 relative to the first stopper 2. In this embodiment, two through-holes are provided side by side in the conveying direction Z.

[0020] As shown in FIG. 3, the regulating member 8 regulates movement of the first stopper 2 in a direction (in this embodiment, the conveying direction Z (see FIG. 1)) intersecting the movement direction (in this embodiment, the left-right direction) of the first stopper 2. In this embodiment, the regulating member 8 is a roller 8b rotatably held by an arm 8a extending in the left-right direction from the support member 12. The roller 8b abuts against the front and rear surfaces, in the conveying direction Z, of a roller receiving member 21 fixed to the first stopper 2. In this way, the regulating member 8 regulates movement of the first stopper 2 in a direction intersecting the movement direction when the first stopper 2 moves in the movement direction. In this embodiment, the stopper device 1 further has a lower roller 8c abutting against the lower side of the roller receiving member 21. In this way, downward movement of the first stopper 2 when it moves in the left-right direction is regulated.

[0021] The absorbing member 10 absorbs the impact in the movement direction of the first stopper 2. In this embodiment, the absorbing member 10 is a shock absorber that supports the slide rod 22 and absorbs the impact in the movement direction (left and right direction) transmitted from the slide rod 22.

[0022] The support member 12 supports the restricting member 8 and the absorbing member 10. The support member 12 has flanges 12a on both ends in the conveying direction Z. The support member 12 is fixed to the loading platform C1 via the flanges 12a.

[0023] As shown in FIG. 4 , in the stopper device 1 configured as described above, the wheel X2 of the forklift X abuts against the second stopper 4. When the wheel X2 abuts against the second stopper 4, the second stopper 4 receives an impact from the wheel X2. The impact received by the second stopper 4 is transmitted to the absorbing member 10 via the connecting member 6 and the first stopper 2 and absorbed. At this time, the restricting member 8 restricts movement of the first stopper 2 in a direction (the conveying direction Z in this embodiment) intersecting the movement direction (the left-right direction in this embodiment), thereby preventing a load from being applied to the slide rod 22 in a direction intersecting the movement direction of the first stopper 2. With the wheel X2 abutting against the second stopper 4, the second stopper 4 is pushed downward by the wheel X2 and is sandwiched between the ground G and the wheel X2. This locks the second stopper 4. Furthermore, in the stopper device 1, the bottom surface of the second stopper 4 extends parallel to the ground G. This increases the friction between the second stopper 4 and the ground G, and the second stopper 4 is more reliably locked by the wheel X2.

[0024] When the second stopper 4 is locked, the first stopper 2 connected to the second stopper 4 via the connecting member 6 is also locked. This locks the vertical and horizontal positions of the first stopper 2. Therefore, the first stopper 2 is locked in a position where it overlaps the mast X1 of the forklift X in the vertical direction. As a result, even if the wheel X2 rides up on the second stopper 4, the mast X1 abuts against the first stopper 2. Therefore, this stopper device 1 can more reliably stop the forklift X. As a result, it is possible to prevent the forklift X from colliding with the loading platform C1 and damaging the loading platform C1. If the second stopper 4 were not present, the first stopper 2 could slip under the mast X1. If the first stopper 2 slips under the mast X1, the forklift X could not be stopped in an appropriate position. Furthermore, in the stopper device 1, the second stopper 4 extends parallel to the first stopper 2, so that no matter what position in the conveying direction Z the wheel X2 abuts on the second stopper 4, the wheel X2 can abut on the second stopper 4 before the mast X1 abuts on the first stopper 2. This makes it possible to more reliably lock the up and down positions of the first stopper 2.

[0025] As described above, according to the present disclosure, it is possible to provide the stopper device 1 that can stop the forklift X more reliably.
