Deceleration control is performed.

Next, the operation of the work feeding device of the present invention will be described together with an example of use. The workpiece feeding device (A) of the present invention is installed in, for example, a drum processing line for manufacturing an electrophotographic photosensitive member. That is, as shown in FIG. 3, the work feeding device (A) transfers the work (W) to the standby position inside the both-end processing machine (D) via the shuttle transfer device (B) and the supply conveyor device (C). The work delivery gate (3) is placed facing the shuttle transfer device (B) so as to be transferred. Then, the workpiece (W) on which predetermined machining has been performed by the both-end processing machine (D)
Is a double-end processing machine (D) via an unloading conveyor device (E).
It is laid out so that it is carried out of the device.

The shuttle transfer device (B) is configured such that the transfer table (B1) having a V-groove formed on the upper surface of the work (W) for mounting the work (W) is moved by a cylinder device with a stroke of about 500 mm. It is configured to reciprocate in the direction. The shuttle transfer device (B) pushes the work (W) toward the supply conveyor device (C) by operating the pushing member (B2) incorporated in the transfer table (B1) at the end of the movement stroke. It is configured to put out.

The work lifter (4) of the work feeding device (A) has a work (W) diameter range of 15 to 30 mm,
Of each adapter corresponding to 30 to 50 mm, 50 to 80 mm, and 80 to 110 mm, for example, a diameter of 30 to 50 mm
The adapter corresponding to the work (W) is selectively mounted. Then, the work placement surface (1) of the work stocker (1)
As shown in FIG. 1, a plurality of works (W) are placed side by side on A). The work mounting surface (1A)
A plurality of works (W) can be placed on the left and right, and can be placed on upper and lower tiers.

In the work feeding device (A), as shown in FIG. 4, when the work lifter (4) descends below the work mounting surface (1A), each work (W) is moved to the work mounting surface (1). Rolling toward the guide side wall (2) along the inclination of 1A), the leading work (W) rolls on the support member (6) and the work lift surface (4A) to guide the side wall (2).
Abut.

Here, as shown in FIG. 5, when the work lifter (4) starts rising, the work (W) in contact with the guide side wall (2) is supported on the work lift surface (4A). The other work (W) in the vicinity is the guide slope (4
It is pushed back along B). And the work lift surface (4
A) The work (W) supported on the top is, as shown in FIG.
As the work lifter (4) rises, it rises along the guide side wall (2). At this time, since the work (W) is given a rolling behavior toward the guide side wall (2) due to the inclination of the work lift surface (4A), it does not accidentally fall. Further, since a plurality of escape grooves (4C) extending in the vertical direction are formed on the outer surface of the work lifter (4) in contact with the pushed back work (W), the work lifter (4)
Can smoothly rise with smaller frictional resistance.

When the work lifter (4) rises to near the upper portion of the guide side wall (2), the lifter rise detection sensor (7)
(W) supported on the work lift surface (4A)
, The lift of the work lifter (4) is detected. At that time, the work (W) is placed on the work feeding stage (2A).
Does not exist and the work confirmation sensor (8) does not detect the work (W), the rising speed of the work lifter (4) is decelerated. The work (W) supported on the work lift surface (4A) rises to a position where the work (W) supported on the work lift surface (4A) can roll on the work feeding stage (2A) at the upper end of the guide side wall (2). , And rolls to the work feeding stage (2A) side, abuts against the gate plate (3D) of the work feeding gate (3), and the work feeding stage (2A).
It is placed on top (see FIG. 7).

When the work (W) is placed on the work unwinding stage (2A), the presence of the work (W) is detected by the work confirmation sensor (8), and the work lifter (4) is immediately lowered. And the work lifter (4)
As shown in FIG. 4, it is lowered to below the work mounting surface (1A),
The work (W) is supported on the work lift surface (4A) again and starts to rise.

When the work lifter (4) rises again near the upper portion of the guide side wall (2), the lifter rise detection sensor (7) detects the rise of the work lifter (4). At this time, the work (W) is placed on the work feeding stage (2A).
Since the work confirmation sensor (8) detects the presence of the work (W) while the is placed, the work lifter (4) is immediately lowered. Then, the work lifter (4) is controlled to rise again at the lower end, so that the work lifter is repeatedly moved up and down while the work (W) is placed on the work feeding stage (2A).

On the other hand, as shown in FIG. 8, the work (W) placed on the work delivery stage (2A) is moved from a control device (not shown) by a gate plate (3D) of the work delivery gate (3). 3. The shuttle (B) of the shuttle transport device (B) shown in FIG.
1) It is paid out. Then, the shuttle transfer device (B) is configured to operate the work (W) on the transfer table (B1) at a timing where the number of the works (W) on the supply conveyor device (C) and the unloading conveyor device (E) is always one. To the supply conveyor device (C) side.

When the work (W) on the work feeding stage (2A) is fed to the shuttle transfer device (B),
Since the work confirmation sensor (8) does not detect the work (W), the lowering control of the work lifter (4) is released.
As a result, the work lifter (4) moves the work placement surface (1).
Each work (W) on A) is sequentially conveyed onto a work unwinding stage (2A). Then, the work (W) is sequentially fed out to the shuttle transport device (B) side as the work feeding gate (3) is sequentially opened and oscillated upward. Therefore, according to the work feeding device of the present invention, the cylindrical work (W) can be reliably fed one by one.

In the operation of the workpiece feeding device according to the present invention, a plurality of workpieces (W) are placed on the workpiece mounting surface (1A).
When the work lifter (4) rises, a plurality of vertically overlapping works (W) are supported on the work lift surface (4A) in a multi-stage manner. Rise. The work (W) supported in multiple stages falls sequentially due to the frictional contact force with the guide side wall (2) and the weight of the work (W), and finally two to three works (W) are lifted on the work lift surface. (4A) in some cases.

In the case described above, the lifter lift detection sensor (7) detects the lift of the work lifter (4) by passing the uppermost work (W) supported on the work lift surface (4A). At this time, when the work confirmation sensor (8) does not detect the work (W), the work lifter (4)
Is controlled to decelerate. Then, the uppermost work (W) supported on the work lift surface (4A) rises to a position where it can roll on the work feeding stage (2A), and then the work lifter (4) is immediately controlled to lower. Thus, only the uppermost work (W) is placed on the work feeding stage (2A).

In the present invention, the work confirmation sensor (8)
Detects the presence of the work (W) and controls the rise of the work lifter (4) when the lifter rise detection sensor (7) detects the rise of the work lifter (4). It is also possible to control to stop at

[0031]

As described above, according to the present invention, the work accommodated in the work stocker rolls to the guide side wall along the inclination of the work mounting surface, and the work lifter rises. It is supported on the work lift surface and rises. At this time, the work is provided with a rolling behavior toward the guide side wall by the work lift surface inclined in the same direction as the work mounting surface, so that the work does not drop accidentally. When the uppermost work supported on the work lift surface rises to a position where the work can be rolled onto the work unwinding stage, only that work rolls toward the work unwinding stage at the upper end of the guide side wall, and the work unwinding gate is moved. It is fed out by opening. Therefore, according to the present invention, cylindrical or columnar works can be reliably fed one by one at a predetermined timing.

In the case where a guide slope is formed at the upper end of the work lifter and an escape groove is formed on the outer surface of the work lifter, into which the comb-like support member is loosely fitted, at the lower end of the work lifter, the upper surface of the work lifter is mounted. The work can be reliably supported on the work lift surface via the support member. When the work lifter is lifted, another work can be pushed back along the guide slope, and the contact area between the work lifter and the other work can be reduced.
The work lifter can be raised smoothly.

In a work feeding device in which the upper end of the work lifter is detachably configured as several types of exchangeable adapters, and each of the adapters has a work lift surface having a different width, the diameter of the work lifter can be changed by selecting the adapter. A wide range of different workpieces can be handled.

When a lifter lift detection sensor for detecting the lift of the work lifter and a work confirmation sensor for detecting the presence of the work on the work feeding stage are provided, when the lifter lift detection sensor detects the lift of the work lifter, When the work confirmation sensor detects the presence of the work, the lift of the work lifter is regulated, and when the work confirmation sensor does not detect the presence of the work, the lifting speed of the work lifter can be reduced, and the operation of feeding the work one by one more reliably. Can be performed.
