[Industrial applications]

 The present invention relates to a transfer workbench device, and more particularly, to a structure of a transfer workbench device capable of easily carrying a heavy work in any direction, not limited to a specific direction, in a transfer work place and easily performing the transfer work. .

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a transfer workbench device has been used particularly in the case of carrying heavy goods or the like on a workbench surface in a work place relating to various logistics such as a production factory, a distribution center, or an airport terminal. As shown in FIG. 4, in this transfer work table device, a transfer work table surface 7 (the transfer work table surface is actually a relatively wide surface, but only a part thereof is shown in the drawing) is provided with a through hole 8 to carry out the transfer work table. A rotary wheel 1 is rotatably attached to a surface of a base surface 7 by a rotary wheel base 5 such that only a part of the upper surface thereof protrudes. The rotary hall stand 5 has a bracket 5a having a support rotary axis X on which the rotary wheel 1 can revolve.

A large number of through holes 8 are bored on a relatively wide transfer worktable surface 7, and each of the through holes 8 has a rotary wheel 1 supported on a rotary wheel base 5, which is a supporting member thereof, as shown in FIG. It is arranged so as to be held and project above the table surface. On the transfer work table surface 7 in such a state, a transfer worker carries out a moving operation by manually pushing, for example, manually by placing a heavy object placed on a predetermined transfer table on the rotating wheels 1. To do. In this moving operation, for example, the work table 7 is not limited to being carried in only a specific direction, but is carried while carrying out direction changes in all directions to a predetermined moving place.

[0004]

[Problems to be solved by the device]

 However, when carrying to a large number of storage areas, etc., the heavy object transferred on the transfer work table surface 7 needs to be moved in all directions as described above, and it is not limited to the linear movement, but it may be moved to the left or right as necessary. I have to turn. The structure in which the transport direction can be freely changed is configured such that the support rotation axis X, which is the revolution axis of the rotation wheel base 5, and the rotation axis Y of the rotation wheel 1, do not match, and an external force is applied in the movement direction. At times, the rotary wheel 1 is oriented in the direction of its movement. That is, the rotating wheel 1 is structured so as not to receive an unexpected mechanical resistance when moving a placed heavy object in a predetermined direction, that is, a swinging motion in which the bracket 5a is directed in a specific direction by a so-called external force. It is supported by a flexible structure.

Therefore, the through hole 8 is naturally formed in a size that allows the revolution of the rotary wheel 1, and as shown in FIG. 4, for example, the distance between the support rotary shaft X and the rotation shaft Y is increased. Since the rotation radius must be set to a distance a that is the sum of b and the radius r of the rotating wheel 1, it is perforated in a large circular shape with a margin so as not to hinder this revolution.

In the conventional transfer work table, a considerable space is formed between a large number of through holes 8 and the rotary wheel 1 and the rotary wheel stand 5 installed below each of the through holes 8, and An operator may accidentally step into the through hole or drop an item such as a part or a document during the transfer of the item, which may cause anxiety, inconvenience, or danger during the operation. In addition, the use of the workbench for a long period of time causes dust and dirt that has fallen from the through holes 8 to interfere with the operation of the rotary wheel 1, and is unsanitary especially in food-related workplaces. However, it has disadvantages such as inconvenience. The present invention is intended to solve the above-mentioned drawbacks, and its purpose is to improve the safety and workability of a transfer worker by eliminating any anxiety and danger during the transfer work of heavy objects. It is in.

【Example】

 Hereinafter, a specific configuration of an embodiment of the present invention will be described in detail with reference to the accompanying drawings. 1 is a side view of this embodiment, and FIG. 2 is a front view thereof. The same parts as those of the conventional type shown in FIG. The features will be described. The transfer workbench device 10 according to the present embodiment has a structure in which the rotary wheel 1 projects into a large number of through holes 8. The rotary wheel 1 is rotatably attached to a bracket 5a of a rotary wheel base 5 which is a support member thereof, and an L-shaped attachment member 3 is fixed to a side surface of the bracket 5a. The lid plate 2 is attached to the upper end of the attachment member 3.

The lid plate 2 is formed with an appropriately rectangular opening 9 such that only an upper part of the rotary wheel 1 is projected at a position deviated from its center position, and the outer peripheral contour is a disk plate. It is a member of. The lid plate 2 is fixed to the outer side of each of the left and right brackets 5a by, for example, bolts 4 on the upper surface of an L-shaped mounting member 3 fixed by, for example, welding. The center of the lid plate 2 is located on the center of rotation of the rotary wheel base 5, and the radius R0 of the lid plate 2 can be configured to be approximately the same as the revolution radius a. In this embodiment, the radius R0 is set larger than the revolution half diameter a. The diameter of the cover plate 2 is set to be slightly smaller than the diameter of the through hole 8 formed in the transfer work table surface 7, and the cover plate 2 is attached to a position forming the same surface as the work table surface 7. ing.

In the transport workbench device 10 configured as described above, since the cover plate 2 that closes the through hole 8 formed in the transport workbench surface 7 is rotatably provided above the rotating wheel base 5, At the time of carrying work, when a worker goes up on the carrying work table 7 to carry heavy objects, the through hole 8 is blocked, so that there is no need to worry about stepping down like the conventional type. As a result, it is possible to carry out extremely safe transportation work without worrying about dropping other items.

The present invention is not limited to the above-mentioned embodiment, and various modifications such as the shape of the lid plate, the bracket, etc., the support structure, etc. can be made. That is, in the above-described embodiment, the lid plate 2 is arranged inside the through hole 8 (the diameter of the lid plate 2 is smaller than that of the through hole 8). The diameter of 2 may be larger than that of the through hole 8.

In the present invention, when the diameter of the cover plate 2 is made larger than the through hole 8, as shown by imaginary lines 2a and 2b in the upper and lower positions of the cover plate 2 in FIG. The outer peripheral edge portions of the lid cover plates 2a and 2b are configured to come in contact with the top or bottom of the transfer work table 7. According to such a configuration, not only the through hole 8 can be completely blocked, but also the contact between the transport worktable 7 and the cover plates 2a, 2b is prevented when the bracket 5a and the rotary wheel base 5 rotate. It can have a reinforcing effect. In particular, this reinforcing effect is a very useful effect in the transfer work table 10 for transferring heavy objects. The lid plate of the present invention has a stepped structure in which a portion indicated by a solid line (closing lid plate 2) and a portion indicated by an imaginary line (closing lid plate 2a or 2b) are combined. It is also possible to adopt a structure in which the transfer work table 7 is sandwiched between the both lid cover plates 2a and 2b.
