Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work transfer device for transferring a pressed plate-like work while rotating it from a certain state around a line in the transfer direction by a predetermined angle to a cleaning step.

[0002]

2. Description of the Related Art For example, in the manufacturing process of a sheet metal shutter (refer to S in FIG. 1) for a 3.5-inch (90 mm) flexible disk cartridge, the shutter is formed into a U-shape by pressing and then washed to remove oil. It is placed in a cleaning basket for cleaning, but in order to improve cleaning efficiency, the shutter should be opened during the transfer from the pressing process to the cleaning process so that the opening of the U-shaped shutter faces downward and is put in the predetermined position of the cleaning basket. It is necessary to stand with its opening facing down.

For this reason, conventionally, at the exit of the pressing process, the opening of the shutter faces upward. Therefore, the shutter is gripped and lifted by the first gripping device, rotated, and turned to the side, and then the second. The gripping device grips from the opposite side, and after the transfer is completed, the opening is rotated downward.

[0004]

However, in the case of reversing the work in this way, two gripping devices are required, the size of the device becomes large, and it is difficult to adjust the gripping force, and the product is scratched. There was a problem that there was also. In addition, to lie a standing plate-shaped work on the side
It is easy to use a jet of air, etc., but it was difficult to stand upside down.

In view of the above situation, the present invention provides a work which can be transferred to a cleaning process by rotating a pressed plate-shaped work while rotating it from a certain state around a line in the transfer direction by a predetermined angle. An object is to provide a carrier device.

[0006]

For this reason, according to the present invention, the first and second pulleys are respectively provided on two planes parallel to a reference plane that includes the conveyance direction line and is orthogonal to the plate surface of the workpiece on the conveyance direction inlet side. And the third and fourth pulleys are symmetrically arranged on the planes in which the first and second pulleys are present, with the workpieces sandwiching the first and second pulleys.

Then, the fifth to eighth pulleys are arranged on the exit side in the carrying direction with the first to fourth pulleys rotated by a predetermined angle around the carrying direction line. And the first
A round belt is wound around each of the first and fifth pulleys, the second and sixth pulleys, the third and eighth pulleys, and the fourth and seventh pulleys. And constitutes a work transfer device.

[0008]

In the above structure, on the inlet side in the transport direction,
The work includes a round belt wound around the first pulley, a round belt wound around the second pulley, a round belt wound around the third pulley, and a round belt wound around the fourth pulley. It is sandwiched between the belt and the belt, and conveyance is started.

Then, due to the twisting of these round belts, they are conveyed while being rotated around the conveying direction line in the conveying process. Then, on the outlet side in the transport direction, the work is round belts wound around the fifth pulley and the sixth belt, and round belts wound around the eighth pulley and the seventh belt. It is discharged from between the round belt wound around the pulley and the original belt in a state rotated from the original state around the line in the conveying direction by a predetermined angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 is an overall view of the pressing process to the cleaning process of the sheet metal shutter S for a 3.5-inch flexible disk cartridge, in which 1 is a pressing machine, 2 is an air-flow type tumbling device, and 3 is the present invention. The conveying devices 4 are washing machines.

In the pressing machine 1, as shown in the pressing step in FIG. 4, blanking (single cutting and punching of windows for both sides) and bending (bending) are continuously performed on the plate material. , U-shaped. In this final stage, the shutter S has its U-shaped opening facing upward. Then, the airflow-type tilting device 2 applies an airflow to the shutter S to turn the shutter S sideways.

Then, a transfer device 3 according to the present invention described later.
Thus, the shutter S is conveyed from the sideways state while being rotated by 90 degrees around the conveying direction line, and is transferred to the washing machine 4 with the opening portion facing downward. In the washing machine 4,
As shown in FIG. 5, the shutters S are conveyed one after another.
Is extruded laterally (in the direction of arrow A) by a pusher (not shown), and is arranged in the lateral direction, for example, by 26 pieces.

The cleaning basket 7 can accommodate a shutter S of 26 × 7 = 182 pieces, and the accommodation is completed by seven insertion operations. As shown in FIG. 6, the cleaning basket 5 has 26 plate-shaped guides 5a extending in the front-rear direction in the lateral direction, which are in a state as shown in (a) or (b) of FIG. The position of the shutter S is regulated.

After the storage of the shutter S is completed, the cleaning basket 5 is sent in the direction of arrow C by a conveyor (not shown) to reach the cleaning liquid storage section 6. Next, the transport device 3 according to the present invention will be described with reference to FIGS. At the entrance side in the carrying direction, the first and second planes are parallel to the reference plane that includes the carrying direction line and is orthogonal to the plate surface of the shutter S.
The pulleys 31 and 32 of the
The first and second pulleys 31, 32 are symmetrically placed on the plane where the pulleys 31, 32 of
And the fourth pulleys 33, 34 are arranged.

The fifth to eighth pulleys 35 to 38 are arranged on the exit side in the conveying direction with the first to fourth pulleys 31 to 34 rotated 90 degrees about the line in the conveying direction. Here, the first pulley 31, the fifth pulley 35, and the second pulley
32 and the sixth pulley 36, the third pulley 33 and the eighth pulley 38, and the fourth pulley 34 and the seventh pulley 37,
Wrap round rubber belts 41 to 44, respectively.

In such a conveying device 3, on the entrance side in the conveying direction, the shutter S includes a round belt 41 wound around the first pulley 31 and a round belt 42 wound around the second pulley 32. , Round belt wrapped around the third pulley 33
It is sandwiched between 43 and the round belt 45 wound around the fourth pulley 34, and the conveyance is started. Then, due to the twisting of the round belts 41 to 44, the round belts 41 to 44 are conveyed while being rotated clockwise around the conveying direction line in the conveying process.

On the exit side in the conveying direction, the shutter S is attached to the round belt 41 wound around the fifth pulley 35, the round belt 42 wound around the sixth pulley 36, and the eighth pulley 38. From between the round belt 43 wound around and the round belt 44 wound around the seventh pulley 37, the sheet is discharged in a state rotated from the original state by 90 degrees around the conveying direction line. Round belt
The shutter S sandwiched between 41-44 is a round belt 41-
Since 44 is an elastic body, and after the pressing step and before the cleaning step, since the surface of the shutter S has oil, there is no risk of scratches.

[0018]

As described above, according to the present invention, a press-formed plate-shaped work can be moved from one state to a predetermined direction around the conveying direction line without damaging the product by means of an inexpensive device. It is possible to obtain the effect that it can be transported while being rotated by an angle and transferred to the cleaning step.
