Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings showing an embodiment of the present invention.

1 and 2, in a plurality of magazines 2 arranged to be movable up and down in the frame 1, the sheets 5 are arranged in a stacked state in a certain amount so that the magazines move vertically, and the top magazine Moves horizontally and is disposed on the upper side of the automatic withdrawal and bending device according to the present invention. The magazine is in a state where the bottom side is open.

In the magazine 2, the sheets are stacked with both ends supported and maintained, and the automatic withdrawal and bending device of the present invention is a sheet stacked through the open bottom of the magazine, as shown in the enlarged view of FIG. Among them, a pull-out part 10 for adsorbing and pulling out sheets one by one from the bottom side, and a bent part 30 for supplying to a subsequent process by bending both sides of the sheet pulled out and arranged by the pull-out part vertically with respect to the central part. Includes.

3 to 5, a pair of cylinders 11 and 12 in which the lead portions 10 are close to each other and each of the piston rods 111 and 121 are moved forward and backward in opposite directions, and a piston rod of each of the cylinders Support plates (13,14) in which the central portion of the "H" shape is fixed to each of the (111,121), adsorption parts (131,141) provided on both sides of each of the support plates (13,14), and fixed with a bracket to the end of the output shaft And a motor 15 capable of forward and reverse rotation to rotate the cylinders 11 and 12 together.

In addition, the bent portion 30 is a link member 33 fixed to the piston rods 32 and 42 of the cylinders 31 and 41 mounted on each of the brackets 21 and 21 ′ fixed to the frame ends on both sides. The bending members 34 and 44 are connected to the link members 33 and 43 by a piston rod 32 and 42 that advances when the cylinders 31 and 41 are operated through the bending members 34 and 44 Is rotated at right angles inward with respect to the bracket. When the cylinder 31 mounted on the one side bracket 21 is operated, the cylinder 41 mounted on the other side bracket 21 ′ is maintained in a stopped state, so that the cylinders 31 and 41 alternately operate.

Each of the adsorption parts 131 and 141 is composed of a plurality of vacuum adsorbers mounted on each of the support plates 13 and 14, and the vacuum adsorbers of the support plate 13 and the vacuum adsorbers of the support plate 14 are independently of each other. Is controlled. That is, when the vacuum adsorbers of the adsorption unit 131 provided on one side of the support plate 13 adsorb the sheet, the vacuum adsorption units of the adsorption unit 141 provided at the support plate 14 on the other side are maintained in a vacuum released state.

The motor 15 is a step motor and can be rotated forward and backward by a preset angle.

In the embodiment shown in the figure, it is rotated forward by 90° twice, and then rotated twice by 90° in the reverse direction. That is, the sheet adsorbed on the adsorption part 131 of the support plate 13 facing upward is rotated 90° in the forward direction, and the sheet is bent in a horizontally disposed state, and then rotated again 90° to be disposed to face downward. And the sheet falls. Then, the suction unit 141 of the support plate 14 facing upward adsorbs the sheet, rotates 90° in the reverse direction, and is disposed horizontally, the sheet is bent, and then rotates further 90° in the reverse direction so that it is directed downward.

6 and 7, the adsorption part 131 mounted on the piston rod 111 advancing upward from one side of the cylinder 11 adsorbs the lowermost sheet of the laminated sheets from the bottom (FIG. 2), Then, the cylinders 11 and 12 are rotated 90° in the forward direction by the motor 15 so that the sheet adsorbed to the adsorption unit 13 is disposed opposite to the bent part at one side.

In that state, as shown in FIG. 8, when the cylinder 41 of one bent portion opposite to the rotated seat 5 operates and the piston rod 42 advances, a bending member connected to the link member 43 ( As 44) is rotated inwardly at a right angle to the bracket, one side of the sheet is bent at a right angle.

Then, as shown in Figs. 9 to 12, the cylinders 11 and 12 are further rotated 90° in the same direction by the motor 15, and the adsorption unit mounted on the support plate 13 of the cylinder 11 ( In a state in which the bent sheet adsorbed by 131 is directed downward, vacuum is released by the vacuum adsorbers of the adsorption unit 131 so that the sheet falls. Although not shown in the drawing, the falling sheet is transferred to a subsequent process by a conveyor belt.

After the sheet is dropped from the adsorption part 131 as above, when the piston rod 111 of the cylinder 11 retreats, the piston rod 121 of the other cylinder 12 advances upward and is provided at its end. The lowermost thing of the sheet stacked on the magazine is sucked and retracted by the vacuum absorbers of the suction part 141, and then the cylinder 41 of the bracket fixed to the opposite frame is operated by rotating 90° in the reverse direction to operate the piston rod. As 42 advances and the bending member 44 connected to the link member 43 rotates inward at a right angle, one side of the sheet is bent, and then the sheet is released by vacuum release from the vacuum absorbers of the suction unit 141 to release the bent sheet. It falls.

As above, the cylinders 11 and 12 are rotated twice by 90° in the forward direction by the motor 15, and then rotated twice by 90° in the reverse direction, and the piston rods 111 and 121 of the cylinders 11 and 12 are repeated. ) Of the adsorption units (131,141) alternately adsorb the sheet, and then the bending members (34,44) are operated by the cylinders (31,41) in a rotated state to sequentially perform the process of bending the sheet once and the sheet Is continuously pulled out and bent, then dropped and transferred to the subsequent process.

Therefore, the automatic sheet pulling and bending device for a packaging box of the present invention has a compact configuration of a pullout unit for pulling out a sheet and a configuration for bending one side of the pulled sheet, so that the manufacturing cost of the device can be greatly reduced. Since the process is shortened, the space occupied by the device is minimized, so that equipment cost can be greatly reduced, and the sheet can be efficiently bent and the packaging box can be manufactured by automating the sheet pull-out and bending process, thereby improving productivity.

The present invention can be used to automate a process of automatically drawing and bending a sheet for packaging.
