[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like member unloading device for sequentially taking out a plurality of formed plate-like members one by one and preparing them for the next step.

[0002]

2. Description of the Related Art After a plurality of molded plate-like members, for example, lid members, are stacked in the same direction, they are sequentially taken out one by one from an uppermost one by an automatic machine or the like, and the next step, for example, the lid member is placed in a container Prepare for the process of attaching to Since the plurality of formed plate-like members are sequentially fitted and stacked, the stacking height can be suppressed, which is convenient.

[0003] An automatic machine for taking out the above plate-like member includes:
For example, this is performed by a device having a suction member such as a suction cup, and the suction member descends from above to suck the uppermost plate-shaped member, and thereafter is taken out upward and moved to the position of the next step.

[0004]

However, in taking out the above-mentioned plate-like members, the stacked plate-like members are tightly fitted to each other by the influence of their own weight and the like. When the object was taken out, the next plate-like member was also taken out together, which sometimes hindered the work.

In such a case, conventionally, an operator manually peels off the next plate-like member, and when the plate-like member is large and heavy, such as a lid of a drum tube, two workers are required. Need.

In order to eliminate this peeling work, a method of stacking the above plate-like members in the facing direction to eliminate the mutual fitting can be adopted. However, there is a problem that an operation for inverting each sheet is required, and the apparatus becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a plate-like member unloading device capable of reliably taking out plate-like members stacked in the same direction one by one.

[0008]

According to the present invention, an object of the present invention is to provide a height-adjustable loading table on which a plurality of molded plate-like members are loaded, and an uppermost plate provided above the loading table. A pick-up device having a suction member that moves up and down between two positions to take out the plate-shaped member; and a plate-shaped member that contacts the upper surface of the plate-shaped member held by the suction member at the raised position of the suction member. A vibration device that excites the
And a contact member that contacts the upper surface of the plate-shaped member .

[0009]

[0010]

According to the present invention having such a construction, the suction member of the take-out device descends to suck and hold the uppermost plate-like member and rise. When the suction member rises to a predetermined height, the plate-like member held by the suction member is excited by the vibration device, and when the next plate-like member is lifted together, it is dropped by vibration, and the suction member is removed. Only one plate member is held.

Next, when the plate-like member unloading device also has a contact member, the plate-like member receiving the above-mentioned excitation impacts the contact member at the frequency of the excitation. The next plate member entrained by the force is more effectively peeled off.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a front view of the apparatus of this embodiment, and FIG. 2 is a side view. In the figure, reference numeral 1 denotes a table-like loading table, whose height can be freely adjusted by a link 2 and a cylinder 3. 1 and 2 are shown at different table heights. A plurality of formed plate-like members W (W1, W2,...), For example, a lid member of a drum tube are stacked on the loading table 1 so that the same surface is in the same direction.

A rail member 6 is provided above the loading table 1 between the horizontal members 5 supported by the columns 4, and the take-out device 7 is guided by the rail member 6 as shown in FIG. (A position for the next step, indicated by a two-dot chain line).

The take-out device 7 has a cylinder 9 provided vertically on a guided member 8 guided on the rail member 6, and extends downward at the upper end of a rod 10 of the cylinder 9. A movable frame 12 is provided, which is vertically guided by a block 11 connected to the guided member 8. The block body 11 extends below the rail member 6 and, as can be seen in FIG. The arm member 1
A member 14 extending downward is provided at both ends of 3, and a contact member 15 is attached to a lower end of the member 14. The shape of the contact member 15 is not limited, but it is preferable that the contact member 15 be in contact with the plate member W on a surface having a protective member softer than the plate member W.

A vibration device 16 is attached to the center of the arm member 13 connected to the block body 11, and a disk-shaped vibration member 18 is provided at the tip of a rod 17 that vibrates up and down. (See FIG. 3). The vibration member 18
Is set at a height position where it comes into contact with the plate member W almost simultaneously with the contact member 15.

On the other hand, the lower part of the movable frame
As described above, a suction pipe 20 having a rubber suction member (suction board) 19 at its tip is attached to suck the plate-shaped member W. The suction pipe 20 is connected at its upper end to a suction device by a hose (not shown) or the like. Absorption member 1
9 has some degree of freedom in the height direction and the inclination due to its own elasticity and the like. The movable frame 12 is reciprocated by the cylinder 9 between an upper position where the plate member W sucked and held by the suction member 19 is in contact with the excitation member 18 and a lower position separated by a predetermined distance H therefrom. It has become. In this lower position, two sets of sensors 21A and 21B and 22A and 22B arranged with a width at the height.
(For example, a photoelectric sensor), and controls the cylinder 3 so that the uppermost plate-shaped member W1 on the loading table 1 enters the above-mentioned height width. On the other hand, a set of sensors 23A and 23B for detecting the second plate member W2 when the plate members overlap and are lifted by two or more are arranged at the rising position of the plate member W1. Has been established. Further, a sensor 24 for detecting the presence or absence of the plate-shaped member W1 at the above-mentioned raised position.
(For example, a proximity switch).

Next, the operation of the apparatus of this embodiment having the above configuration will be described.

First, an arbitrary number of plate-like members W are loaded on the loading table 1 in the same direction.

Two sets of sensors 21A, 21B and 2
While 2A and 22B do not detect the plate member W, the loading table 1 is raised. When the uppermost plate member W1 of the plurality of plate members W on the loading table 1 enters between the two sets of sensors,
The loading table 1 is stopped, and the uppermost plate-shaped member W is stopped.
1 comes within a predetermined allowable height width.

Next, the movable frame 12 is lowered to the lower position by the operation of the cylinder 9. At the lower position, the suction member 19 suction-holds the uppermost plate-shaped member W1.

Thereafter, the movable frame 12 moves up to the upper position. The sensor 24 confirms the presence or absence of the plate member W1 at the position, and the sensors 23A and 23B confirm whether there is a second plate member W2 to accompany. As a result, when the sensor 24 issues a signal indicating that the plate member W1 does not exist, the suction member 19 descends again to remove the plate member. When the sensor 24 confirms the plate member W1 and the sensors 23A and 23B do not confirm the second plate member W2, the take-out device 7 is guided by the rail 6 because the take-out is a regular take-out. Move to the right position shown in FIG.

The sensor 24 is a plate-like member W 1
Is confirmed, and when the sensors 23A and 23B detect the second plate-shaped member W2, the excitation member 18 abutting on the plate-shaped member W1 vibrates to excite the plate-shaped member W1 up and down.
The plate-like member W1 usually has elasticity, and generates flexural vibration at its end. Since the contact member 15 is in contact with the end of the plate member W1, the plate member W1 is impacted against the contact member 15 due to the bending vibration. I will be. The second plate-like member W2 is separated from the plate-like member W1 by this impact force, falls on the stacked plate-like members, and waits for the next suction operation.

[0024]

[Effects of the Invention] As described above, the present invention excites the first member up and down when the second member accompanies the second member when the plate member is sucked and taken out. Since it is made to fall, the next process can be started without any trouble, and the work efficiency is improved. Further, if the contact member is provided at the time of excitation, an impact force can be applied to the second plate-shaped member, and the peeling-off can be more reliably performed.
