[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work reversing device, and more particularly to a work reversing device used for reversing a relatively heavy work.

[0002]

[Prior art]

 Conventionally, when reversing a work such as a metal plate, for example, the work is manually performed while the work is suspended by a crane or the like.

[0003]

[Problems to be solved by the device]

 However, reversing work performed by using a crane for each individual work is extremely complicated, and there is the inconvenience that the workability is significantly reduced. It had a fatal problem of burdening it.

Further, there is a drawback that the work itself is likely to be damaged due to the difficulty of such work, and therefore, the means is not always the optimum work reversing means.

Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and enables a smooth reversal without causing damage to the work, thereby facilitating a series of work. The task is to

[0006]

[Means for Solving the Problems]

 That is, in order to solve the above problems, the present invention has a base 11 that can be raised and lowered, a pair of work placement plates 9a and 9b rotatably provided at both ends of the base 11, and the base 11 described above. When the workpiece mounting plates 9a and 9b are raised, the workpiece mounting plates 9a and 9b should be rotated so that they are substantially horizontal, and the workpiece 18 mounted on one of the workpiece mounting plates 9a can be delivered to the other workpiece mounting plate 9b. A work reversing device including a cam mechanism that allows the work placement plates 9a and 9b to rotate so as to face each other when the base 11 is lowered.

[0007]

[Action]

 Therefore, in the reversing device characterized by the above configuration, when the base 11 is raised, the pair of work placing plates 9a and 9b are rotated substantially horizontally by the cam mechanism. After the work to be inverted is placed on one of the work placing plates 9a, when the base 11 is lowered, the work placing plates 9a and 9b are rotated by the cam mechanism and both are inclined. Faced to each other, the work is held between the work mounting plates 9a and 9b in a state of being tilted toward the other work mounting plate 9b side.

Then, when the base 11 is raised again, both work placing plates 9a and 9b rotate in a substantially horizontal state with the work being delivered to the other work placing plate 9b. As a result, the work is turned upside down.

【Example】

 An embodiment of a work reversing device according to the present invention will be described below with reference to the drawings.

In FIG. 1 to FIG. 3, reference numeral 1 denotes a gantry frame formed by a plurality of angle members 2. The gantry 1 has a truncated cone shape having a roller 3 at a lower end portion and a screw rod 4 at one end. The stand 5 is provided so as to be movable and fixed at a predetermined position. Reference numeral 6 denotes a holding plate which is vertically installed so as to face the upper surface of the gantry 1.

Reference numeral 7 denotes a screw jack vertically arranged at the substantially central portion of the gantry 1, which is driven by a break motor 8. Reference numerals 9a and 9b denote flat work placement plates, the inner surfaces of which are rotatably connected to a base 11 divided into three as shown in FIG. The screw jack 7 is connected to the lower surface of the center base 11a, but the bases 11a and 11b are inclined so that the bases 11a and 11b are lowered toward the other work placing plate 9b.

Reference numeral 13 denotes a pair of cams arranged at the lateral positions of the work placing plates 9a and 9b. The arc-shaped cam grooves 14 formed in the cams 13 are provided on both side surfaces of the work placing plates 9a and 9b. A pin, which is a cam follower 16 that is projected laterally via the plate-shaped body 15, is slidably engaged. Incidentally, the arc center O of the cam groove 14a of one cam 13a is configured to be located at a position H higher than the arc center O'of the cam groove 14b of the other cam 13b. Reference numeral 17 is a rod-like body that projects along the longitudinal direction of the substantially central portion of each base 11a, 11b.

The reversing device according to the present embodiment has the above-described configuration. Next, a case where the device is used to reverse a work made of a relatively heavy metal plate will be described.

First, as shown in FIG. 1, when the brake motor 8 is operated to raise the base 11 via the screw jack 7, the cam follower 16 slides in the cam groove 14 of the cam 13. Since the cam groove 14 is formed in an arc shape, the work placing plates 9a and 9b are rotated so as to open each other and are held by the holding plate 6 in a substantially horizontal state. In this state, the work 18 is placed at a predetermined position on the one work placing plate 9a.

After that, when the base 11 is lowered by the screw jack 7, contrary to the previous step, the work placing plates 9a and 9b are rotated to face each other by the cam mechanism as shown in FIG. However, since the arc center O of the cam groove 14a of one cam 13a is located above the arc center O'of the cam groove 14b of the other cam 13b, the work placement plates 9a and 9b are Since the workpieces 18 face each other in an inclined state, the upper end side of the workpiece 18 is held in a state of being inclined toward the other workpiece placing plate 9a side. In this case, the rod-shaped body 17 provided on the base 11 has a function of promoting the tilting operation of the work 18.

Next, when the base 11 is raised again by the screw jack 7 in the same manner as described above, the work placement plates 9a, 9b are transferred with the work 18 delivered to the other work placement plate 9b. Is rotated, and the work 18 is turned upside down as shown in FIG. 1 to be placed on the other work placing plate 9b. As a result, the reverse side of the inverted work 18 can be processed.

Thus, the work placing plates 9a, 9b are connected to both ends of the base 11, and the work placing plates 9a, 9b are rotated by a single screw jack 7 by a cam mechanism. Therefore, by appropriately setting the ascending / descending speed of the screw jack 7, the transfer and reversing operation of the work 18 by the work placing plates 9a and 9b can be carried out very smoothly. It is possible to suitably suppress the reaction shock generated when the 18 is reversed, and it is possible to satisfactorily avoid the inconvenience of causing damage to the work 18.

Further, since the reversing device according to the present embodiment has an extremely simple structure, it has an advantage that it can be manufactured at low cost and easily.

In the above embodiment, the screw jack 7 is used as the raising / lowering means of the base 11, but the present invention is by no means limited to this, and any concrete raising / lowering means does not matter.

Further, in the embodiment, since the base 11 is inclined to the other work placing plate 9b side, there is an advantage that the work 18 can be delivered and received favorably, but it is not always necessary to incline it. You can arrange them horizontally.

Further, it is needless to say that the reversing device according to the present invention is not limited to reversing a metal plate and can be applied to reversing various works.

In addition, the shapes of the work placing plates 9a and 9b and the base 11 and the connecting means between the two can be arbitrarily changed within the scope intended by the present invention.

[0023]

[Effect of device]

 As described above, according to the present invention, a pair of workpiece mounting plates rotatably mounted on a vertically movable base are guided and guided by a cam mechanism to be rotated in a substantially horizontal direction and inclined so as to face each other. Since it is configured so that it can be rotated, the work can be placed on one of the work placing plates and the base can be raised and lowered, and the work can be transferred to the other work placing plate with its front and back reversed. Become.

Therefore, the workability is far superior to the conventional reversing work in which each work is hung by a crane and the like, and at the same time, one work placement plate is placed on the other work placement. The work can be delivered to the plate satisfactorily, and thus the special effect that the reversing work can be performed without causing damage to the work has been obtained.

Further, since the work inverting device according to the present invention has a very simple structure as described above, it has a practical effect that it can be manufactured easily and inexpensively.
