Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a workbench device for supporting a work at a height position where a worker is most likely to work in a manufacturing line of a factory, for example.

(Prior Art) A conventional workbench device of this type is generally constituted by a substantially flat workbench that is fixed and arranged substantially horizontally at a height position near the waist of an operator.

(Problems to be solved by the invention) However, when the workbench is fixedly arranged as described above, when the worker uses the workbench device, the work is usually performed near the floor surface. A worker must manually lift and lower the placed work on the work table. Therefore, when the work is lightweight, it does not cause much trouble, but when the work is relatively heavy, May gradually accumulate a feeling of fatigue associated with lifting and lowering of the work, resulting in a problem that work efficiency decreases.

Also, depending on the type of work or work site, it may be preferable in terms of work safety or work efficiency to perform work while the workbench is inclined, but as with conventional workbench devices, workbench work A structure fixed in a horizontal state cannot meet such a demand.

Therefore, the present invention reduces the fatigue of the worker by simplifying the work of raising and lowering the work to the workbench, and also allows the work posture of the work to be arbitrarily changed, thereby improving the work efficiency. It is intended to provide a stand device.

(Means for Solving the Problem) In the present invention, as a concrete means for solving the problem, a tilting frame supported so as to be vertically tiltable at a predetermined height position, and A substantially flat plate-like worktable rotatably supported in a plane direction, a horizontal position at which the tilting frame is tilted integrally with the worktable so that the worktable is substantially horizontal, and the worktable is inclined. First drive means that can be positioned at two tilting positions, and a lower position in the tilting position of the tilting frame that is mounted outside the working table in the thickness direction of the working table. A free-standing work receiver, which projects upward from the upper surface of the work table so that one end of the work placed on the work table can be supported in the plane direction of the work table. Protruding position Position and second drive means capable of positioning in two positions, that is, a retracted position in which the work table is retracted below the upper surface of the work table, and when the work table is set in the tilted position, the work receiver is positioned in the projecting position. When the work table is tilted from the tilt position to the horizontal position, the work support is held in the projecting position, and after the work table is positioned from the tilt position to the horizontal position, the work support is set. Set the position to the retracted position,
Further, there is provided control means for controlling the first drive means and the second drive means in association with each other so as to position and hold the work receiver at the projecting position when the work table is tilted from the horizontal position to the tilted position. It is characterized by that.

(Operation) In the present invention having such a configuration, the first
Since the drive means and the second drive means operate in cooperation with each other, the following actions are obtained in each work.

(1) When a work is placed on the work table In this case, when the work table is set to the tilted position, the work receiver is set to the projecting position in conjunction with this. Therefore,
The work is held in a tilted state by placing the work on a tilted workbench and placing it on the workbench and supporting the lower end side of the work on a work receiver.

If the workbench is tilted to the horizontal position side from this state, the work is kept supported by the work support and gradually rises from the inclined position to approach the horizontal position.When the workbench is set to the horizontal position, the work support is also retracted. It is set to the position and the work supporting action by the work receiving is released. Therefore, in this state, the work receiver is located below the upper surface of the work table, and since relative interference between the work receiver and the work in the work table rotation direction is avoided, the work table is rotated while rotating. It becomes possible to perform a predetermined work on the work.

(2) When lowering the work from the work table after the work is completed In this case, the work table is tilted from its horizontal position to the tilt position side, and at this time, the work receiver also projects from its retracted position in conjunction with this. Since the work is moved and held in the position, the work is prevented from sliding down on the lower side in the tilt direction due to tilting of the work table. Therefore, the work table can be tilted to the tilt position while the work is supported by both the work table and the work receiver. In this tilted position of the workbench, since one end of the work is positioned near the floor surface, the worker moves the work a short distance to lower the work from the workbench onto the floor surface. be able to.

(3) When it is desired to perform a predetermined work on the work while the work is tilted, the work table and the work support are set in the tilted position and the work support is positioned at the projecting position. The work is supported by and.

(Effect of the Invention) Therefore, according to the workbench apparatus of the present invention, the worker can move the work up and down by a short distance to raise and lower the work to and from the workbench. Compared with other workbench devices that require the worker to move the work by the vertical distance between the floor surface and the workbench, the operator's fatigue level is reduced and work efficiency is improved. A practical effect of being able to contribute can be obtained.

Further, since the work table and the work receiver can support the work in an inclined state at the tilted position of the work table,
The work can be performed not only in a horizontal state but also in a tilted state, and work corresponding to various work conditions can be performed, and work safety and work efficiency can be further improved. It will be.

(Embodiment) A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a workbench apparatus according to an embodiment of the present invention. This workbench device includes a support column 1 that is erected on a base 5.
The tilting frame 2 is attached to the upper end of the tilting frame 2 via a swing support shaft 8 so as to be tiltable in the vertical direction (direction of arrow AB).
The tilting frame 2 is tilted obliquely as shown in FIG. 1 by the first cylinder 11 (corresponding to the first driving means in the scope of utility model registration claims) arranged between the tilting frame 2 and the base 5. The tilted position and the horizontal position which is almost horizontal as shown in FIG.

Further, on the upper surface side of the tilting frame 2, a flat plate-shaped workbench 3 having a predetermined size is arranged along the tilting frame 2 via a rotation support shaft 4 in the plane direction (arrow E-F).
Direction) is rotatably supported. In addition, this workbench 3
Can be easily rotated manually.

Further, at a position on the lower side in the tilted position of the tilting frame 2, an arm-shaped work receiving member 6 having a work receiving member 7 having a> -shaped cross-sectional shape at its tip is vertically moved via a fulcrum pin 9 ( It is attached rotatably in the direction of arrow CD. The arm length of the work receiving member 6 is appropriately set so that the work receiving member 7 can be positioned at a position outside the work table 3 in the plane direction as shown in FIG.

The work receiving member 6 is disposed between the work supporting member 6 and the cylinder supporting member 13 provided on the workbench 2 side, and the second cylinder 12 is disposed.
Due to the expansion and contraction movement (corresponding to the second driving means in the scope of utility model registration claims), the work receiver 6 projects upward from the upper surface 3a of the work table 3 as shown in FIGS. 1 and 3. 2 and the retracted position where the work receiver 7 is located below the upper surface 3a of the workbench 3, as shown in FIG.

As shown in FIGS. 1 and 3, the vertical position of the work receiver 7 in the retracted position is the upper surface 3a of the work table 3.
The end 10a of the work 10 (the automobile door in this embodiment) placed on the work is supported by its corner so that the work 10 can be restricted from moving downward in the direction of inclination of the workbench. It is set relative to 10 shapes.

The tilting of the work table 3 and the movement of the work receiver 7 (that is, the expansion and contraction of the first cylinder 11 and the second cylinder 12) are performed by the control means Z described later in the following linkage.

As shown in FIG. 1, the first cylinder 11 is contracted so that the worktable 3
In the state in which the workpiece is positioned at the tilted position, the second cylinder 12 extends so that the workpiece receiver 7 is positioned at the projecting position and that state is maintained. This state is the work placement preparation complete state. In this state, as shown in FIG. 1, the work 10 is supported on the work table 3 with the end 10a of the work 10 supported by the work receiver 7. It can be placed in an inclined state.

While the first cylinder 11 extends from the state of FIG. 1 and the workbench 3 moves from the tilted position to the horizontal position, the second
The extended state of the cylinder 12 is maintained and the work receiver 7 is left in the protruding position. Therefore, the work 10 does not slide down from the work table 3 and is gradually lifted upward while tilting.

As shown in FIG. 2, when the workbench 3 reaches the horizontal position,
The work receiver 7 that was in the protruding position until then is the second cylinder 12
Is moved downward due to the contraction, and the position is changed to the retracted position as shown in FIG. This state is a workable state, and in this state, it is possible to rotate the work 10 together with the workbench 3 and perform a predetermined work without causing mutual interference with the work receiver 7.

On the other hand, when the work 10 is to be detached from the work table 3 after the work is completed, the work receiver 7 first moves from the retracted position to the projecting position from the state shown in FIG. 2, and the end 10a of the work 10 can be supported. Becomes At the same time, the first cylinder 11 is contracted, and the workbench 3 is gradually tilted from the horizontal position to the tilted position side, finally reaching the state shown in FIG. In this state, the work 10 is removed from the workbench 3.

By operating the workbench 3 and the work receiver 7 in such a procedure, the worker can work on the workbench 3 near the floor during work.
Further, it is only necessary to raise and lower the work 10 on the work receiver 7, and the feeling of fatigue is reduced by the amount that the work 10 needs to be moved a little.

Next, a specific example of the control means Z for realizing the above-described operation will be described with reference to FIG.

The control means Z is composed of an air control circuit as shown in FIG. 4, and has a first switching valve 21 for performing sequence control of the first cylinder 11 and the second cylinder 12, and a first cylinder 11.
The second switching valve 22 for switching the operation of the second cylinder 12, the third switching valve 23 for switching the operation of the second cylinder 12, and the rod of the first cylinder 11.
A first mechanical valve 24 that is opened and closed by an operating pawl 11b provided on 11a and a second mechanical valve 25 that is opened and closed by an operating pawl 12b provided on a rod 12a of the second cylinder 12 are provided. The first switching valve 21 is switching-controlled by a pair of push button valves 31 and 32.

The operation of the control means Z will be described with reference to the operating states shown in FIGS.

As described above, the workbench apparatus operates in the order of FIG. 1 → FIG. 2 → FIG. 3 → FIG. 1 for each work. And the fourth
The figure shows the circuit state in the state of FIG. 1 (that is, the state in which the workbench 3 is set to the tilted position and the work support 7 is set to the protruding position, and the work 10 is supported by the work support 7).

When tilting the workbench 3 to the horizontal position side from this state, first, the first push button valve 31 is operated to operate the first switching valve.
21 is set to the second valve position 21b. Then, the second switching valve 22 is set to the second valve position 22b side by the air pressure from the line 41, and the first cylinder 11 extends (that is, the workbench 3 begins to tilt toward the horizontal position). . In this state, the second cylinder 12 is held in the fully extended state (that is,
Maintain the support state of the work 10).

When the first cylinder 11 reaches the fully extended state (that is, when the workbench 3 is set to the horizontal position), the operating pawl 11b provided on the rod 11a of the first cylinder 11 causes the first mechanical valve to move.
24 is opened and the air pressure from line 42 causes the third switching valve
23 is set to the second valve position 23b side. Therefore, the second cylinder 12 is contracted and the work receiver 7 is positioned at the retracted position (state shown in FIG. 2). Predetermined work is performed in this state.

Next, there is a case of returning from the state of FIG. 2 to the state of FIG. 1 after the work is completed. In this case, first, the second push button valve 32 is operated to set the first switching valve 21 to the first valve. Set to position 21a. Then, the third switching valve 23 is set to the first valve position 23a, the second cylinder 12 gradually extends from the fully contracted state,
Along with this, the work receiver 7 is set from the retracted position to the protruding position (that is, the work 10 can be supported).

When the extension of the second cylinder 12 is completed, at the same time, the operation claw 12 provided on the rod 12a of the second cylinder 12 causes the second cylinder 12 to move to the second position.
The mechanical valve 25 opens, the air pressure from the line 43 causes the two-way switching valve 22 to switch to the first valve position 22a, and the first cylinder 11 starts to contract.

In this way, the control means Z causes the first cylinder 11 and the second cylinder 12 to operate in a predetermined coordinated manner, whereby the above-described series of operations of the workbench apparatus are realized.

When the work is tilted and the work is to be performed on the work, the work table 3 and the work receiver 7 are set to the state shown in FIG. It is enough to support 10 and work.
