Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a device for reversing a plate-shaped workpiece.

[Prior Art] A side wheel-shaped turning frame is rotatably and pivotally attached to a machine frame, a workpiece is inserted into an opening provided in a direction of a pivot of the turning frame, and the turning frame is input. There is a structure in which the material to be processed located on one side is rotated and inverted to be inverted and moved to the other side.

[Problems to be solved by the invention] For example, a plate-shaped material to be processed such as a front door is heavy, and reversing work by simple input induces an occupational disease. A device such as the example is used, but still, the rotation reversing work of the rotating frame requires input,
The occupational diseases mentioned above cannot always be prevented.

Further, the conventional device is only for reversing the work material, and it is necessary to move to the work table in order to perform the work work on the work material after reversing, and it is complicated in the work work. , It is inconvenient for line production in a small factory.

The present invention was devised for the purpose of solving these problems.

[Means for Solving Problems] Vertical movements in which hook-shaped guide frames composed of an upper piece and a vertical vertical piece are provided so as to face each other in a pair on the left and right sides of the machine frame, and are interposed between opposing guide frames. On a possible intermediary material, each free end side is hinged to the base end of each of a pair of work material mounting plates supported by the machine frame upper edge.
A protrusion that engages with a guide groove of the same shape formed in the guide frame is provided on the intermediate member, and a connecting rod that is separately engaged with the guide groove is provided on a connecting piece that is provided on the lower surface of the mounting plate. The machine frame is provided with a drive device and its operating cylinder, and the drive device is composed of a drive piece that communicates with a piston rod of the operating cylinder and an operation piece that rotates together with the drive piece. The intermediary member is vertically moved along the vertical vertical piece to vertically raise both mounting plates, and a pin is fixed to the intermediary member, and the pin is engaged with the arc-shaped long hole formed in the operating piece. It is a combined structure.

[Embodiment] The drawings show an embodiment of a device for reversing a plate-shaped workpiece according to the present invention, in which 1 is a machine frame, and a pair of guide frames 2, 2 are provided on opposite sides of the machine frame 1, respectively. 2 and 2 are provided relative to each other with a gap 5 therebetween.

The guide frame 2 is formed in a hook shape consisting of an upper piece 2a and a vertical vertical piece 2b, and a guide groove 6 of the same shape is provided on the inner surface thereof. A protrusion 7 provided on the intermediary member 3 is movably engaged with the guide groove 6.

The intermediary member 3 is composed of a main body 8 arranged in the central portion of the gap 5 and side members 9 arranged on both sides in the longitudinal direction of the main body 8 in a direction orthogonal to the main body 8, and the protrusions are formed on the outer surface of the side member 9. A child 7 is provided, engages with the guide groove 6, and is installed in the guide frames 2 and 2 so as to be vertically movable.

Reference numeral 4 denotes a placing plate of the work material a. The placing plate 4 has its base end hinged to opposite ends of the intermediary material main body 8 by hinges 10 so as to be rotatable, and the free end side of the intermediary material 3 is It is adapted to be supported by the machine frame 1 at the top dead center position.

FIG. 11 shows a connecting piece that is provided on the lower surface of the mounting plate 4. A connecting rod 24 is provided on the outer surface of each of the connecting pieces 11, 11, 11, and 11, and the connecting rod 24 is an intermediary member. Similar to the protrusion 7 provided on the side member 9 of No. 3, it is movably engaged with the guide groove 6.

Reference numeral 12 is a cylinder for operating the driving device 13, and the cylinder 12 is a support piece 1 projecting from one side outside the guide frame 2.
The base ends of the piston rods 4 and 14 are attached to the piston rod 1 on the free end side.
Reference numerals 5 and 15 are connected to the tips of the drive pieces 16 and 16.

The drive pieces 16 and 16 are fixed to the interlocking shaft 18 at their base ends together with the arcuate actuating pieces 17 and 17, and the interlocking shaft 18 is the guide frame 2
Is rotatably supported by a support piece 23 provided on the machine frame 1 through the.

The free ends of the actuating pieces 17, 17 have the gap 5
Direction-side, and the operating pieces 17 and 17 are provided with arc-shaped elongated holes 19 and 19, and pins 20 and 20 projecting from the elongated holes 19 and 19 at intermediate positions of the main body 8 of the intermediary member 3. Are engaged.

Then, when the cylinder 12 is operated in the state of FIG. 1, the piston rod 15 pulls the driving piece 16, which causes the interlocking shaft 18 to rotate, and the operating piece 17 having the base end fixed to the interlocking shaft 18. The free end side turns downward.

The intermediary material pin 20 engaged with the long hole 19 of the operating piece 17 is
The intermediary member 3 to which the pin 20 is attached is pressed and lowered by the lowering of the operating piece 17, and the guide member 6 of the protrusion 7 is provided in the gap 5 within the gap 5.
The descending direction is regulated by the engagement relationship of (3) to descend in the vertical direction.

Since the base end of the placing plate 4 is hinged to the intermediary member 3, the pair of placing plates 4 and 4 rise in the opposite direction as the intermediary member 3 descends, and at the same time as the connecting rod 24. The rising angle is regulated by the engagement relationship of the guide grooves 6, and the intermediary material 3
The workpiece a placed on one of the mounting plates rises as the mounting plate 4 rises in the vertical direction, and the edge of the workpiece a is received by the upper end surface of the intermediary member 8 and released. Will be supported by the other mounting plate (FIG. 3), and if the cylinder 12 is moved in the opposite direction at this point, the intermediary member 3 will rise and the mounting plates 4, 4 will gradually open, and The workpiece a is pushed up by the upper end surface of the material main body 8 and is inverted from one mounting plate to the other mounting plate so that the back side of the material can be processed.

21 is an auxiliary cylinder (not necessarily required), and the auxiliary cylinder 21 assists the rising of the mounting plate 4 in synchronization with the cylinder 12. It goes without saying that the pair of cylinders 12 and 12 are synchronized with each other.

Reference numeral 22 is a seat for the mounting plate 4.

[Advantages of the Invention] Since the present invention has the above-described configuration, the actuating piece is rotated by operating the cylinder, and the pin engaged with the long hole of the actuating piece is pressed. It is possible to easily turn over the plate-shaped work material by moving vertically without depending on the input. In addition, since the work material has a structure in which it is supported by being inverted and moved between the mounting plates, the mounting plate itself can be used as a processing table, and is a device suitable for use in a small factory. is there.
