[Prior art]

 A plurality of molded plate-shaped members, such as lid members, are stacked in the same direction, then sequentially taken out one by one from the topmost one by an automatic machine, etc., and in the next step, for example, the step of attaching the lid member to the container Prepare for Since the plurality of molded plate-shaped members are sequentially fitted and stacked, the stacking height can be suppressed, which is convenient.

An automatic machine for taking out the plate-shaped member is performed by an apparatus having an adsorption member such as a suction cup, and the adsorption member descends from above to adsorb the uppermost plate-shaped member. After that, it is taken out upward and moved to the position of the next process.

[0004]

[Problems to be solved by the device]

 However, when taking out the above-mentioned plate-shaped members, the stacked plate-shaped members are tightly fitted to each other due to the influence of their own weight, etc., and when the topmost one is taken out, The plate-shaped member was also taken out together, which hindered the work.

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

In order to eliminate the peeling work, a method of stacking the plate-shaped members in a facing direction to eliminate mutual fitting can be adopted, but the stacking height becomes extremely high and the automatic The machine needs a reversing operation for each sheet, which causes a problem that the apparatus becomes complicated.

It is an object of the present invention to solve the above problems and provide a plate-shaped member unloading device that can reliably take out plate-shaped members stacked in the same direction one by one.

[0008]

[Means for Solving the Problems]

 According to the present invention, the above-mentioned object is to provide a height-adjustable loading platform for loading a plurality of molded plate-like members, and to remove the uppermost plate-like member provided above the loading platform. A take-out device having an adsorbing member that moves up and down between positions, and a vibrating device that excites the plate-shaped member in the up-down direction by contacting the upper surface of the plate-shaped member held by the adsorbing member at the raised position of the adsorbing member. This is achieved by having and.

Further, in addition to the configuration of the above invention, it is possible to achieve more effectively by providing a contact member that contacts the upper surface of the excited plate-shaped member.

[0010]

[Action]

 In the present invention having such a configuration, the suction member of the take-out device descends and the uppermost plate member is suction-held and lifted. When the suction member rises to a predetermined height, the plate member held by it is excited by the vibrating device, and if the next plate member is lifted together, it falls due to the vibration and the suction The member holds only one plate member.

Next, when the plate-shaped member carrying-out device also has a contact member, the plate-shaped member receiving the above-mentioned excitation impacts the contact member at the frequency of this excitation, and The subsequent plate-like member accompanied by the impact force is more effectively peeled off.

【Example】

 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 is a table-shaped loading platform, the height of which can be freely adjusted by a link 2 and a cylinder 3. Note that the table heights shown in FIGS. 1 and 2 are different from each other. A plurality of molded plate members W (W1, W2, ...), for example, lid members for the drum tubes are stacked on the stacking table 1 so that the same surface faces the same direction.

A rail member 6 is provided above the loading platform 1 between lateral members 5 supported by columns 4, and a take-out device 7 is guided by the rail member 6 as shown in FIG. It is adapted to reciprocate laterally between other positions (positions for the next step, indicated by a chain double-dashed line).

The take-out device 7 has a cylinder 9 provided upright 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 body 12 is provided which is vertically guided by a block body 11 connected to the guided member 8. The block body 11 extends to the lower side of the rail member 6 and, as seen in FIG. 3, an arm member 13 protruding laterally is attached to the lower end thereof. A member 14 extending downward is provided at both ends of the arm member 13, and an abutting member 15 is attached to a lower end of the member 14. The shape of the abutting member 15 is not limited, but it is preferable that the abutting member 15 can be brought into contact with the plate-shaped member W by a surface having a protective member that is softer than the plate-shaped member W.

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

On the other hand, as shown in FIG. 3, a suction pipe 20 having a rubber suction member (suction plate) 19 at the tip thereof is attached to the lower portion of the movable frame 12 to suck the plate member W. ing. The suction pipe 20 is connected at its upper end to a suction device by a hose or the like (not shown). The suction member 19 has a certain 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 attracted and held by the suction member 19 contacts the excitation member 18 and a lower position separated from the excitation member 18 by a predetermined distance H. It is supposed to do. At the lower position, there are two sets of sensors 21A and 21B and 22A and 22B (for example, photoelectric sensors) arranged at a height with a width, and the uppermost plate-like member on the loading platform 1 is provided. The cylinder 3 is controlled so that W1 falls within the above height range. On the other hand, a set of sensors 23A and 23B for detecting the second plate-shaped member W2 when the plate-shaped members are overlapped and lifted by two or more are arranged at the raised position of the plate-shaped member W1. It is set up. Further, a sensor 24 (for example, a proximity switch) that detects the presence or absence of the plate member W1 in the raised position is provided.

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

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

While the two sets of sensors 21A and 21B and 22A and 22B do not detect the plate member W, the loading platform 1 is raised. When the uppermost plate-shaped member W1 of the plurality of plate-shaped members W on the loading platform 1 enters between the two sets of sensors, the loading platform 1 stops and the uppermost plate The member W1 is positioned 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 sucks and holds the uppermost plate member W1.

After that, the movable frame body 12 rises to the upper position. The sensor 24 confirms the presence or absence of the plate member W1 at that position, and the sensors 23A and 23B confirm whether or not there is a second plate member W2 to accompany. As a result, when the sensor 24 issues a signal that the plate member W1 does not exist, the suction member 19 descends again to take out the plate member. When the sensor 24 confirms the plate-shaped member W1 and the sensors 23A and 23B do not confirm the second plate-shaped member W2, the take-out device 7 is guided to the rail 6 because the take-out is normal. Move to the position on the right side as shown in FIG. 1 to enter the next step.

When the sensor 24 confirms the plate-shaped member W1 and the sensors 23A and 23B detect the second plate-shaped member W2, the excitation member 18 that contacts the plate-shaped member W1 vibrates. Then, the plate member W1 is vertically excited. The plate member W1 usually has elasticity, and flexural vibration occurs at its end. Since the contact member 15 is in contact with the end of the plate member W1, the plate member W1 impacts the contact member 15 due to the bending vibration. You will be hit. The second plate-shaped member W2 is separated from the plate-shaped member W1 by this impact force, falls on the stacked plate-shaped members, and waits for the next suction operation.

[0024]

[Effect of device]

 As described above, according to the present invention, when the plate-like member is sucked and taken out, when the second one accompanies, the first one is excited vertically to drop the second one. Therefore, the next process can be started without any trouble, and the work efficiency is improved. Further, if the abutting member is provided at the time of excitation, an impact force can be applied to the second plate-shaped member and the peeling can be made more reliable.
