Abstract

PURPOSE:To separate certainly nonmagnetic materials which are laid one upon another, by taking three ways combinationally in the separating process, such as bringing up the top plate through an engaging piece which is engaged with one side of this top plate, bringing up a top plate suction means diagonally, and blowing in high pressure air between the top plate and the second plate. CONSTITUTION:The top plate 41' of the built-up plates 41 set in the fixed position of a separating device 68, is attracted to a suction plate 42 by the operation of an air cylinder 34, and then, the cylinders 34, 54 are moved forward and high pressure air is ejected from a nozzle 67. In this way, the saw-teeth 50 of a saw-toothed body 51 move upward as they are engaged with the top plate 41', and at the same time, a suction frame 37 moves upward and diagonally. Consequently, as a high pressure air stratum is formed between the top plate 41' and the second plate, both plates are separated certainly and the top plate 41' is brought up. Then, a cylinder 44 is moved back and the separation is confirmed by a sensor 43, and after that, the top plate 41' is moved forward and transferred by a transferrer 16. In this system, the plates are separated certainly.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention separates stacked sheets of non-magnetic material, such as stainless steel plates, or non-ferrous metal material, copper plates, one by one, and prepares them for the next pressing process, for example. This invention relates to a method for separating stacked plates used during transportation.

(Prior art) Conventionally, when separating ferromagnetic materials such as iron plates one by one from a stacked state, negative pressure adsorption is not required because the magnetic floater for separation and conveyance does not attract the first plate and repel the second plate. Separation equipment is used, but in this case, because each plate is in close contact with each other, especially thin plates, the topmost plate and the second and subsequent plates are transported together with the next plate. There was a drawback that it was reported that it could interfere with work in the process.

(Problems to be Solved by the Invention) The object of the present invention is to reliably separate stacked non-magnetic material plates one by one from the top end, especially the thin plates, under negative pressure adsorption.

(Means and effects for solving problems) This invention is the first
As shown in the figure, when separating the stacked rough plates 1 one by one from above, the uppermost end plate 2 of the stacked plates 1 is raised diagonally with negative pressure adsorbed, and the uppermost end plate 2 of the stacked plates 1 is
When the uppermost end plate 2 rises diagonally, the engaging pieces 3 that abut and engage diagonally with one side are stacked and engage in diagonal contact with the upper side when the uppermost end plate 2 rises diagonally. The uppermost end plate 2 and the uppermost end plate 2 lifted diagonally and by the engaging piece 3
This method involves blowing high-pressure air 5 into a partial gap 4 formed between the second plate and the second plate.

In response to the upward movement while tilting, the uppermost end plate 41' is separated from the second plate from the uppermost end and is peeled off,
A partial gap is formed between the top end plate 41' and the second plate.

On the other hand, the loading truck 40 has a stack of plates 41 on the one truck 40.
In order to effectively engage the saw teeth 50, a positioning plate 56 is attached via a stay 57, and the horizontal position adjustment in FIG. When the air cylinder 60, which is attached to the air cylinder 60, is moved forward, the uppermost end and the stacked plate 41 in the vicinity thereof are positioned in contact with the contact plate 56, and the uppermost end position of the stacked plate 41 is detected by a photoelectric switch (not shown). At the same time, the lift control of the table lifter 61 on the carry-in cart 40, that is, the table lifter 61 equipped with a hydraulic cylinder-driven pantograph mechanism (not shown) between the carry-in cart 40 and the table 62, is controlled to a substantially constant height by a signal from the photoelectric switch. The count that is held in the
The stacking board 41 is moved by a movable base 63 on a table 62, in this case movable base 63 which is movable on pole casters 66 by rotation of a screw 65 via a handle 64, so that the entire stacking board 41 is connected to the contact plate 56. is a limit switch jLs1 which is [positioned parallel to J, and furthermore, the ascending end and descending end of the table 62 are taken to the stay 57].
．． In addition to being detected by LS2, high-pressure air is blown into the partial gap formed between the uppermost end plate 41' and the second plate to the stay 57 to detect the difference between the uppermost end plate 41- and the second plate. A large number of nozzles 67, in this embodiment, eight nozzles 67 are installed at approximately equal intervals along the longitudinal direction of the contact plate 56.
