Description

[Detailed description of the idea]

[0001]

[Industrial fields of application]

The present invention is used, for example, in a distribution center to transport cargo manually. It relates to a trolley for transportation.

[0002]

[Prior art]

In order to facilitate the loading and unloading of goods on the trolley for transportation of this kind, It is known that a roller conveyor is provided on the upper surface of the platform (for example, -203780 and Japanese Utility Model Laid-Open No. 55-17024).

[0003]

[Problems to be solved by the invention]

However, among the above-mentioned prior arts, the former has a roller conveyor on the upper surface of the base. Since only the aisle is placed, the load slides forward and backward when it is transported, There is a danger of falling.

[0004] In addition, in the latter case, for the purpose of preventing cargo from slipping down, the front and rear of the platform are Although the topper is attached detachably, this stopper can be However, it is extremely time-consuming and difficult to remove. There was a problem such as the loss of the stopper that was attached.

[0005] Therefore, the present invention proposes a trolley with a roller conveyor on the upper surface of the pedestal, in which the cargo is transported. The operability of the stopper that prevents slippage is improved, thereby improving the efficiency of transportation work. The purpose is to provide a trolley for transportation.

[0006]

[Means for solving the problem]

In order to achieve the above object, the trolley for transportation of the present invention has casters on the bottom surface of the trolley. and a push handle erected at one end of the base, wherein the base A roller conveyor is provided on the upper surface, and the upper end of the roller conveyor is placed at the end of this base. Install a stopper that can freely appear and retract with respect to the height of the surface, and make this stopper appear and retract The configuration is such that the operating lever is provided on the push handle.

[0007]

[action]

When loading and unloading items on the roller conveyor, operate the operation lever to release the stopper. It is lowered below the height of the upper end surface of the roller conveyor to enable loading and unloading.

[0008] On the other hand, during transportation, the operation lever is used to move the stopper to the height of the top surface of the roller conveyor. Protrudes further upward to prevent cargo from slipping down on the roller conveyor.

[0009]

【Example】

The carriage 1 for transportation shown in FIG. Rear wheels 3 which are swivel casters and front wheels 4 which are fixed casters, and the rear of the platform 2 A push handle 5 erected at the end, and a roller attached to the upper surface of the base 2 in the left-right direction. Conveyor 6 and the cargo to be conveyed is placed on this roller conveyor 6. be

[0010] At the tip of the base portion 2, there is a roller conveyor 6 that can freely appear and retract with respect to the height of the upper end face of the roller conveyor 6. A pair of stoppers 7 are installed, and the operation lever 8 attached to the push handle 5 It is made to appear and disappear via the sheathed cable 9 or the like (details will be described later).

[0011] When loading and unloading cargo, lower the stopper 7 below the upper end surface of the roller conveyor 6. At the time of transportation, the stopper 7 is raised above the upper end surface of the roller conveyor 6 and the cargo is transported. to prevent it from slipping.

[0012] For loading and unloading at the destination, when the cargo is pushed out from behind, it slides on the roller conveyor 6. Because it moves and moves easily, it far exceeds the range that can be lifted by human power. Not only is it possible to transport heavy loads, but the simple operation makes it possible to work in tight spaces work is facilitated, and workability is improved.

[0013] In addition, in this embodiment, the stopper 7 is installed at the tip of the base portion 2, but the present invention is limited to this. The roller 64 of the roller conveyor 6 may be provided at the rear end instead of the roller 64 of the roller conveyor 6. may be changed from horizontal to vertical (front-to-rear direction), and the stoppers 7 may be provided at both ends.

[0014] A platform 2, a push handle 5, a roller conveyor 6, and a rectangle around the circumference The conveyor frame 61 is made of synthetic steel such as AAS with a layer thickness of about 1 mm on the surface of a thin steel pipe. A resin-coated metal pipe structural material having an outer diameter of about 28 to 32 mm, and AA For synthetic resin molded products such as S or PA, and metal press molded joints formed from

[0015] As shown in FIG. 2 (front view) and FIG. 3 (side view), the operating lever 8 is in an inverted L A set bar 82 is fixed to a shaped handle piece 81, and this set bar 82 A bracket 84 attached to the horizontal machine 51 of the handle 5 via a joint 85 is vertically penetrates in the direction

[0016] A T-shaped groove 86 is provided in the center of the front side of this bracket 84, and the set bar A pin 83 projecting from the intermediate portion of 82 is slidably engaged along the groove 86. there is

[0017] The stopper 7 has a U-shaped frame 71 and a slide shaft 72 as shown in FIG. This slide shaft 72 connects the conveyor frame 61 and the base portion 2. vertically through the bracket 73 attached to the mating split joint 10. be. This slide shaft 72 and the slide shaft 72 inside this bracket 73 A spring 74 is mounted to bias the frame 71 upward.

[0018] At the lower end of the frame 71 and the lower end of the set bar 82 of the operating lever 8, , both ends of the sheathed cable 9 are connected.

[0019] FIG. 5 shows the structure of the roller conveyor 6. A split joint 10 is placed on the base 2. A conveyor frame 61 formed in a rectangular shape with a synthetic resin such as AAS A number of shaped base members 62 are fitted around the base member 62, and the PA A support shaft member 63, which is a molded product of resin, is detachably connected.

[0020] Furthermore, the shaft protruding from the support shaft member 63 has a thickness of about 1 mm on the surface of the thin steel pipe. Resin coating with an outer diameter of about 32 mm coated with polyolefin resin such as PE with a layer thickness of A cap 65 made of polyolefin resin such as PE is welded to the end of a metal pipe. A roller 64 is rotatably mounted.

[0021] Next, the operation of the stopper 7 will be explained. First, in FIGS. 2 and 3, the operating lever When the handle piece 81 of 8 is pulled up, the set bar 82 and the sheathed cable 9 The frame 71 of the connected stopper 7 is pulled down against the spring 74, and as shown in FIG. As indicated by the two-dot chain line, the height is approximately equal to the upper end surface of the conveyor frame 61. As a result, the loading and unloading of the cargo on the conveyor 6 becomes possible.

[0022] Therefore, as shown by the two-dot chain lines in FIGS. When the pin 83 of the set bar 82 is engaged with the upper end of the groove 86, the stopper 7 , the frame 71 remains pulled down.

[0023] Further, from this state, when the handle piece 81 is horizontally rotated to return the pin 83 to the front, The frame 71 and the slide shaft 72 of the stopper 7 are raised by the biasing force of the spring 74. and protruding above the height of the upper end face of the conveyor frame 61, and the set bar 82 and handle piece 81 are pulled down (solid line positions in FIGS. 2, 3 and 4). by this A stopper 7 prevents the cargo on the roller conveyor 6 from sliding down.

[0024]

[Effect of invention]

According to the present invention, the stopper for preventing the cargo from slipping down on the roller conveyor is manually pushed. Since it is operated by the operation lever provided on the handle, its operability is greatly improved. and the possibility of losing the stopper is eliminated. Therefore, transportation work using a trolley Improve work efficiency.
