DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments will be described below with reference to the drawings.
The present invention comprises the following devices. A Lath net mounting part equipped with lifting means. B Edge separating means for suction-separating the edges of the stacked lath nets one by one from above. C Levitation means for levitating the entire lath net upward. D Detection means for detecting that the edges of a plurality of lath nets are separated at one time. E Ejection means for horizontally ejecting levitated lath nets. Peeling means for sucking and peeling downward the edge portion of the lower lath net separated by the detection signal indicating that the sheet is a plurality of sheets. Therefore, the lath net mounting portion (A) provided with the lifting means will be described. In FIG. 1, reference numeral 1 is a lath net mounting plate, and an outer frame 2
The inside is raised and lowered by a pantograph type lifter 3. Mounting plate 1
Is coated with a rust preventive agent on a lath net a of length 1970 × width 554 × thickness 0.8 mm, and 500 lath piles are placed on the lath net a. It is configured so that one a sheet can be separately supplied.

Next, the edge separating means (B) for suction-separating the edges of the lath nets one by one from above is constructed as follows. That is, it is composed of three air cylinders 4 each having a magnet roller 5 at the tip thereof, and is vertically attached above the lath net a at a position approximately 150 mm inside from the long side one side of the lath net a. The lath nets a stacked on the mounting plate 1 are separated from the lath net a below by sucking the edges one by one from above.

Next, the levitation means (C) for levitation of the entire lath net upward comprises a separation plate 6 at the tip of an insertion arm 7 which is reciprocally driven by an air cylinder 8 in the horizontal direction. The insertion arm 7 is inserted by the air cylinder 8 from the edge of the lath net a lifted by the magnet roller 5 in B) to the lower side thereof, and the lathe net a is levitated upward by the separation plate 6 at the tip thereof. Instead of the insertion arm 7, a magnet roller supported by an air cylinder may be provided above the center of the lath net a or above the tip side as a floating means to levitate the lath net.

Next, the detecting means (D) for detecting that the edges of a plurality of lath nets "a" are separated at once includes a sensor 9 which works on the operating principle as shown in FIG. It is provided on the net a. The sensor 9 is a detection head 9a
The receiving coil 9b and the transmitting coil 9c are built in the inside of the, and the alternating magnetic field emitted from the transmitting coil 9c is received by the receiving coil 9b and detected by the difference in the induced voltage. When the lath net a, which is a body, enters, the lath net a reduces the magnetic resistance, so a higher voltage is generated in two lath nets than in one lath net. It is detected that it is lifted by the means (B).

Next, the discharging means (E) for horizontally discharging the levitated net will be described. This is because when the insertion arm 7 is inserted into the lower side of the lath net a by the air cylinder 8 and the lath net a is levitated upward by the levitation means, the long side of the lath net a is attracted by the magnet roller 11. Lath net feed member 1 consisting of three rows of drive magnet rollers
0 is provided on the upper part of the lath net to constitute the discharging means.

Next, the peeling means (F) for sucking and peeling downward the edge portion of the lower lath net, which is separated by the detection signal indicating that the number of sheets is a plurality, is constructed as follows. That is, the peeling means is arranged corresponding to the position of the one air cylinder 4 described above. As shown in FIG. 3, the support arm 19 of the magnet roller 20 is pivotally supported 18 at the tip of the arm 14 of the air cylinder 13.
An arm 16 that swings about a fulcrum 15 is attached to the magnet 9, and the magnet 16 is attached via a spring 22 wound around a support arm 19 between the support bracket 21 of the magnet roller 20 and the attachment portion 17. The roller 20 is elastically supported by the support arm 19. Therefore, when the air cylinder 13 is actuated and the arm 14 projects, the arm 16 swings around the fulcrum 15 as shown by the dotted line, and the support arm 19 moves upward around the fulcrum 18 and the magnet is positioned at a position corresponding to the magnet roller 5. Laura 2
0 is lifted, and the magnet roller 20 attracts the lath net a from the lower side of the lath net a. In this suction state, the arm 14 moves backward by the air cylinder 13 to separate the excess lath net a from the upper lath net a. The above operation is performed by the detection signal from the detection means D.

When the air cylinder 4 is actuated, the long side of the lath net a is attracted and lifted by the magnet roller 5 as shown in FIG. 4, and the magnets shown in FIGS. The lower lath net a is sucked by the roller 20 to drop the excess lath net a. Thereafter, as shown in FIG. 5, by inserting the insertion arm 7 with the air cylinder 8, the lifted lath net a and the dropped lath net a are completely separated, and at the same time the opposite lath net a long side is lifted. As shown in FIG. 6, the lath net a is attracted to the magnet roller 11 of the net feed member 10 and rotated to supply the lath net a to the magnet roller 12 in the next step one by one. According to the apparatus as described above, it is possible to separately supply the lath nets a to which the rust preventive agent or the like has been applied and which are attached one by one. Further, although the illustrated lifter is shown as a pantograph type, it may be a hydraulic cylinder type and the edge separating means is composed of three magnet rollers, but it is not always necessary to use three.
The levitation means need not be two separation plates. Further, the peeling means need not be one magnet roller. The design can be changed arbitrarily within the spirit of the present invention.

[0013]

According to the present invention, lath nets that have been piled up after being coated with a rust preventive agent and the like are automatically separated one by one and supplied to the equipment for the next process in a short time. be able to.
