[Prior art]

 In general, as a technical means for separating articles from a deposit, a means for separating and supplying the stacked plate-like bodies (sheets) one by one (a so-called sheet feeding device) is known, and particularly handling thereof is known. What is performed by a vacuum device is known.

There is also known a device (eg, a depalletizer) for loading and unloading articles from the top of a pile by suction.

By the way, the target article relating to the present invention is a relatively small-sized rigid or semi-rigid plate-like object, and is made of a thin resin plate used as a partition plate of a distribution box or the like.

Conventionally, the mechanical means for separating and taking out the partition plates of this kind accumulated and stored is separated from the bottom of the pile by a push-down member or the like in a dharma-removing type rather than being performed by suction as described above (extraction). ) Was often done.

[0006]

[Problems to be solved by the device]

 However, there have been many problems such as scratches due to the partition plates rubbing against each other, or defective extrusion when there is warpage.

Under these circumstances, it was considered to switch the take-out means so as to load and unload articles from the top of the pile by suction, but again, problems such as failure of adsorption and holding and double adsorption are taken into consideration. Was occurring. In particular, it is difficult to prevent this when accumulating and storing thin objects in close contact.

The present invention has been made in view of the above circumstances, and solves the above problems and provides a relatively small and rigid or semi-rigid plate-like body such as a resin partition plate of a distribution box. The uppermost plate of the pile is adsorbed and held by the lower limit of the stroke of the vacuum adsorbing means, and air is blown into the lower surface of the adsorbed plate to properly maintain the separation and single holding of the plate. At the same time, a swinging or oscillating step that moves up and down in small steps in the upward movement process is taken, and the sheet is rotated to the upper limit of the stroke and pushed out to the gripper that holds it in the supply position, and one plate-like body is securely and scratch-free. (EN) A device for taking out a plate-like body which can be taken out separately.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention fixes the upper and lower stroke limits of the vertical suction stroke of the vacuum suction means in order to separate and take out the plate-like bodies accumulated in the storage container one by one, In addition, in the plate-shaped body take-out device in which the lower limit of movement is variably controlled to be taken out one by one from the top of the pile by suction, a storage container provided with slits in the stacking direction of the plate-like bodies and A vacuum suction means for sucking and holding the uppermost plate-like body of the stack at the lower limit of movement, and a vacuum suction means arranged on the lower surface of the plate-like body which is arranged apart from the vacuum suction means and sucked through the slit of the storage container. An air jetting means for blowing air, the vacuum suction means and the air jetting means are integrally fixed through a swirl cylinder, and a cylinder drive means for driving and controlling the vertical stroke of both devices is provided. Is.

A storage container provided with a slit in the stacking direction of the strips, a vacuum suction unit that always suctions and holds the uppermost plate of the pile at the lower limit of the stroke, and is arranged separately from the vacuum suction unit. An air jetting unit that vertically moves integrally and blows air to the lower surface of the plate-like body adsorbed through the slit of the storage container to appropriately maintain the separation and single holding of the plate-like body, and the vacuum adsorbing means. And change the attitude of the air ejection means Cylinder drive means that are integrally fixed via an effective swing cylinder, and the swing stroke or vibration step in which the vertical strokes of both means move up and down in small steps during the upward movement process, and the posture change by turning is performed at the upper movement limit. A drive control mechanism including the above is provided.

Here, the cylinder driving means is an air cylinder or an electric cylinder, the air ejecting means is vertically separated from the lower surface of the suction device of the vacuum suction means by a distance corresponding to the plate thickness of the plate-shaped body, and It is said that a nozzle is placed opposite to the slit on the outside of the storage container, and compressed air is blown to the lower surface of the plate during the upward movement from immediately after adsorption to the limit of rising.

Then, the uppermost plate-shaped body of the pile is adsorbed and held, and air is blown to the lower surface of the adsorbed plate-shaped body to properly maintain the separation and single-sheet holding of the plate-shaped body and the upward movement. In the process, stepping up or down in small swings or oscillating steps, swinging at the upper limit of stroke and feeding out to the gripper that holds the supply posture, release the negative pressure of the vacuum suction means (or convert it to positive pressure), It is possible to separate and take out the plate-shaped bodies one by one without any damage.

【Example】

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

FIG. 1 is an explanatory front view of a plate-shaped body take-out device according to an embodiment of the present invention.

Here, 1 is a vacuum suction means, 11 is an adsorption device, 2 is an air ejection means, 21 is a nozzle, 3 is an air cylinder (cylinder drive means), 4 is a swiveling cylinder, 5 is a storage container, and 6 is a plate. The strips and X are the take-out devices for the strips.

As shown in the figure, a relatively small, rigid or semi-rigid plate-like body (6) such as a resin partition plate of a distribution box is deposited in the storage container (5). The side wall of the storage container (5) is provided with slits (not shown) in the stacking direction of the plate-like bodies (6).

The vacuum suction means (1) is driven and controlled to fix the upper limit of the vertical stroke and to variably control the lower limit of the stroke, and is always the top plate of the pile at the lower limit of the stroke. The body (6) is adsorbed and held.

The air jetting means (2) is fixedly arranged apart from the vacuum suction means (1), and vertically moves integrally, and is sucked through the slit of the storage container (5). Blow air into the lower surface of (6). Here, the air ejecting means (2) is vertically separated from the lower surface of the adsorber (11) of the vacuum adsorbing means (1) by a distance corresponding to the plate thickness of the plate-like body (6), and the accommodating container (5) ) The nozzle (21) is placed opposite to the slit on the outside, and compressed air is blown into the lower surface of the plate (6) during the upward movement from immediately after adsorption of the plate (6) to the rising limit.
