2. Description of the Related Art As shown in FIGS. 4 (I) and (II), an elastic member 33 such as a leaf spring is attached to a lower vibrating body 31 and an upper vibrating body 32.
And a linear track 35 composed of a groove is provided above a track member 34 supported by the upper vibrating body 32. The upper vibrating body 32 reciprocates and vibrates, and the workpiece W moves along the track 35. The vibrating linear feeder 30 for transporting the workpiece is widely used as a work transport device.

When a vibrating linear feeder 30 conveys a work W whose both sides are relatively inclined, such as a piece of shogi, one side of the work W is located on one side of the opposite side 35a of the truck 35. And the workpiece W cannot be transported in a state where the posture is constant.

Therefore, as shown in FIGS. 5 (I) and 5 (II), a work transfer surface 36 inclined in the width direction is formed above a track member 34 supported by the upper vibrating body 32, and the work transfer surface 36 is formed. By providing a linear width guide 37 below 36, the work W is transferred in a state where one side of the work W is in contact with the width guide 37, and the work W is transferred while maintaining a constant posture. be able to.

[0005]

However, FIG.
In the case of the vibrating linear feeder as shown in (I) and (II), since the work W itself is transferred to the downstream side in an inclined state, troubles such as clogging at a connection portion with the next process occur. It is easy to use
Also in the case of taking out one piece at a time, the posture must be changed to a horizontal state after holding the work in an inclined state, and there is a disadvantage that the structure of the taking out apparatus becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a work transfer apparatus capable of transferring a work whose both side surfaces are relatively inclined in a flat state without giving an inclination angle and in a state where a constant posture is maintained. To provide.

[0007]

According to a first aspect of the present invention, a guide member for supporting a part of the bottom surface of a work is fixedly arranged with its work supporting surface substantially horizontal. Work transfer means for supporting the bottom surface of the work and transferring the work in one direction is provided on one side of the guide member, and the work is provided on the work support surface of the guide member and on the work transfer surface of the work transfer means, respectively. Therefore, a configuration in which linear width guides are provided at intervals slightly larger than the maximum width is adopted.

Here, as a work transfer means, a flat work transfer surface is provided on the upper side, and a track member provided with a width guide on the work transfer surface is reciprocated to transfer the work along the work transfer surface. A vibrating linear feeder or a belt conveyor can be employed.

With the above construction, the work supported on the guide member and the work transfer surface of the work transfer means is transported to the downstream side by the work transfer means, and the rotational force is generated during the transfer. In response to this, one side surface is pressed against the width guide of the guide member, and moves to the downstream side in a fixed posture in which one side surface contacts the width guide.

According to a second aspect of the present invention, in order to solve the above-mentioned problems, two work transfer means for supporting a work and transferring the work in one direction are transferred in a state where the work is straddled by each work transfer means. The two work transfer means are arranged side by side so that a speed difference is provided between the work transfer speeds of the two work transfer means, and a linear width guide is provided on the work transfer surface of each work transfer means at an interval slightly larger than the maximum width of the work. Is adopted.

Here, the two work moving means may have the same or opposite work transfer direction. When the transfer direction of the work is reversed, the work transfer speed of the work transfer means for transferring the work in the forward direction is set to be higher than the work transfer speed for transferring the work in the reverse direction.

Further, the two work transfer means may be a vibrating linear feeder or a belt conveyor. Further, a combination of a straight feeder and a belt conveyor may be used.

As described above, by providing a speed difference between the work transfer speeds of the two work transfer means, the work conveyed to the downstream side over the two work transfer means can be rotated at the time of the transfer. In response, the one side is pressed against the width guide of the low-speed side work transfer means, and the one side moves to the downstream side while maintaining a constant posture in contact with the width guide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 (I) and (II), the work transfer device comprises a combination of a fixed guide member 1 and a vibrating linear feeder 10.

A flat work support surface 2 for supporting a part of the bottom surface of the work W is formed above the guide member 1, and a linear width guide 3 is provided on one side of the work support surface 2. . The guide member 1 is fixedly arranged with the work support surface 2 being horizontal. Reference numeral 4 denotes a support for supporting the guide member 1.

The vibrating linear feeder 10 includes the lower vibrating body 1
The upper vibrator 12 is elastically supported by connecting both ends of an elastic member 13 made of a leaf spring to the upper vibrator 1 and the upper vibrator 12, and the upper vibrator 12 supports the track member 14. A flat work transfer surface 15 is formed above the track member 14, and a linear width guide 16 is formed on the work transfer surface 15.
Is provided.

In the vibrating linear feeder 10, the work transfer surface 15 is located on the same plane as the work support surface 2 of the guide member 1, and the interval between the width guides 3, 16 is slightly smaller than the maximum width of the work W. The guide member 1 is juxtaposed so as to be wide.

Now, a work W having the same shape as the shogi piece is placed so as to straddle the work supporting surface 2 of the guide member 1 and the work transfer surface 15 of the linear feeder 10, and the track member of the linear feeder 10 is placed. When the work 14 reciprocates, the work W is transferred to the downstream side by applying a feed force by contact with the work transfer surface 15.

At this time, the work W receives a movement resistance on one side due to the contact of the guide member 1 with the work support surface 2, so that a rotational force is applied to the work W. For this reason,
One side of the work W is pressed against the width guide 3 of the guide member 1 and moves downstream while maintaining a constant posture in which one side of the work W comes into contact with the width guide 3. For this reason, the workpiece W can be transferred in a flat state without any inclination angle and in a fixed posture.

In the work transfer apparatus shown in FIGS. 1 (I) and (II), the work W
However, instead of the linear feeder 10, the belt conveyor 2 is moved as shown in FIGS.
0 may be provided, and the work W may be moved by the belt conveyor 20.

In this case, a width guide 22 is provided on the work transfer surface 21 of the belt conveyor 20 to limit the amount of rotation of the work W and prevent the work W from falling off.

FIG. 3 shows another example of the work transfer device according to the present invention. In this example, a vibrating first linear feeder 1 is used.
0a and the second rectilinear feeder 10b are arranged side by side.

Therefore, the same components are denoted by the same reference numerals and description thereof will be omitted.

The first linear feeder 10a and the second linear feeder 10b are arranged so that the work transfer surface 15 is located on the same plane. The distance between the width guides 16 of the respective linear feeders 10a and 10b is larger than the maximum width of the work W. It is a little bigger.

There is a speed difference between the work transfer speeds of the first straight feeder 10a and the second straight feeder 10b, and the first straight feeder 10a is connected to the second straight feeder 10b.
Work transfer speed is faster.

For this reason, the two linear feeders 10a, 1
When the work W is placed so as to straddle the work transfer surface 15 of the drive line 0b and the straight feeders 10a and 10b are driven,
A rotational force is applied to the work W by a relative speed difference between the work transfer speed by the first straight feeder 10a and the work transfer speed by the second straight feeder 10b, and the work W
One side is pressed against the width guide 16 of the low-speed second rectilinear feeder 10b, and is transported to the downstream side while maintaining a constant posture in which one side comes into contact with the width guide 16.

Here, the first straight feeder 10a and the second straight feeder 10b may be provided with a speed difference while the workpiece W is sent in the same direction, or the first straight feeder 10a is driven. , The second straight feeder 10
b may be stopped to provide a speed difference between the feeders 10a and 10b.

Alternatively, a speed difference may be provided between the feeders 10a and 10b by setting the work transfer direction of the first straight feeder 10a and the work transfer direction of the second straight feeder 10b to be opposite to each other. In this case, the first straight feeder 1
The work W is fed in the forward direction by setting the work transfer speed of the work 0a to be higher than the work transfer speed of the second straight feeder 10b.

In the work transfer device shown in FIG.
Although the two linear feeders 10a and 10b are arranged side by side, two belt conveyors having different belt moving speeds may be arranged side by side. Further, a straight feeder and a belt conveyor may be provided side by side.

[0031]

As described above, according to the present invention, the work is transferred by driving the work transfer means arranged in parallel with the fixed guide member, whereby a rotational force is applied to the work and one side surface of the guide member is provided. It is pressed against the width guide provided on the work support surface of the work, and is transferred downstream while maintaining the state where one side surface is in contact with the width guide. It can be transported while maintaining its posture.

Further, in the present invention, two work transfer means having different work transfer speed differences are provided side by side, and a width guide is provided on the work transfer surface of each work transfer means such that the facing distance is larger than the maximum width of the work. Thus, similarly to the above-described invention, the workpiece can be transferred in a flat state without a tilt angle while maintaining a constant posture.
