Abstract

PURPOSE:To make it possible to separate each work on and after the second one so as to be taken off one by one while starting from the top in order by providing the side surface of a work at the uppermost end with a vector which is rotated downward when the trailing end of a curved section in a semi-circle form winded on a pulley is pressed. CONSTITUTION:A pusher 5 is elevated, the reaction of a belt 37 is regulated at a point where a partition panel 1 at the uppermost step comes down below the center of a pulley 26A with a handle 41 rotated so that positioning is processed in such a way that an upper limit positioning sensor 40 is actuated. In the second place, when an absorption pad 4 is lowered while the belt 37 is driven toward the direction shown by an arrow head 37a so that the partition panel 1a at the uppermost step is sucked up, the second partition panel 1 is separated, being brought up or being bent by the force of the belt 37, the dropping of the panel is thereby prevented when it is carried to the next process.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a device for taking out stacked plates.

(Conventional technology) For example, when putting glass items into boxes.

Partition plates such as cardboard are inserted between products to prevent them from cracking or shifting during transportation.

For example, in FIGS. 4 and 5, square cardboard partition plates 1 are stacked and stored on the upper surface of a pusher 5 inserted from below into a guide plate 2 erected along the four sides. The left end is fixed to the reversing machine 7 provided on the left side, and the right end is attached to the reversible arm 7a.
By reversing the arm 7a upward, it is supplied to the gripping section of the partition plate conveyor 8 provided above.

(Problem to be Solved by the Invention) However, when the uppermost partition plate 1a is sucked with the suction pad 4, the two-port partition plate 1b may also be lifted and fall around the guide plate 2. Therefore, a method of narrowing the interval between the guide plates 2 may be considered, but then there is a risk that the guide plates 2 may break when being lifted up with the suction pads 4. Particularly, as shown in FIG. 4, a nine-section glass product with cuts la for dividing it vertically and horizontally is easily broken.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a plate material take-out device that can easily separate and grasp stacked and easily folded regular-shaped papers one by one from above.

[Structure of the invention]

(Means and Effects for Solving the Problems) The present invention provides a plate material take-out device that sequentially takes out plate-shaped works pushed up by a pusher and stacked in a guide part one by one from the top and sends them to the next process. By installing a belt on the side of the workpiece that rotates downward by pressing the end of a semicircular curved part wrapped around a pulley, it is possible to separate the second and subsequent workpieces and take them out one by one from the top. This is a take-out device.

(Embodiment) Hereinafter, one embodiment of the plate material take-out device of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of the plate material take-out device of the present invention, FIG. 2 is a front view, and FIG. 3 is a right side view.

1 to 3, on the left front side of the L-shaped guide plate 2 when viewed from above, there is vertically provided a partition plate 2a that is movable in the direction of the arrow 2b by a moving mechanism (not shown). The upper end 5a of a push-up machine 5 whose lower end is connected to a threaded rod (not shown) and a motor is inserted, and a partition plate 1 made of cardboard is stacked on the upper end 5a of this push-up machine 5. A pair of guide rods 2C are erected at the right end of 1.

Seats 2d and 28 are fixed to the right end of the rear surface of the guide plate 2, and a hole (not shown) is provided between the seats 2d and 2e, and extends horizontally from front to back. The protrusion 35a of the moving block 35, which has a female screw fitted to a screw stud 41a which is screwed into a female screw (not shown), penetrates back and forth,
The left end of the handle 41 is connected to the right end of the screw stud 41a.

A support plate 25 is vertically attached to the front side of the movable block 35, a reinforcing plate 36 is fixed horizontally to the upper end of the support plate 25, and a block 25a shaped like an inverted U when viewed from the left is attached to the left side of the lower end. The left edge is fixed.

Furthermore, a pair of upper and lower guide rods 22 are laterally attached to the rear left surface of the support plate 25 with bolts 24.
A block 39 having a U-shape in front and side views is provided at the left end of the block 39 so as to be movable left and right via a bearing 21 inserted inside.
A compression coil spring 38 with a repulsion force of approximately 325 g when installed is inserted into the guide rod 22, a flat presser plate 23 is attached to the left end of the guide rod 22 by countersunk screws, and a pulley is attached to the front side of the block 39. 26A is attached to a shaft 26a rotatably inserted into a bearing (not shown).

Further, an electric motor 27 is vertically attached to the upper surface of the block 25a attached below, a bevel gear 28 is attached to the output shaft of the electric motor 27, and the bevel gear 28 is supported at both ends by bearings 30. It meshes with a bevel gear 29 attached to the front side of the shaft 31, and a pulley 26B is attached to the back side of the shaft 31, and a neoprene rubber belt with a diameter of 4 mm is connected between this pulley 26B and the upper pulley 26A. 37 is wound around the belt 37, and this belt 37 is driven by the electric motor 27 at a circumferential speed of about 393
cm/Otoriin.

In the plate material take-out device having such a configuration, the upper end 5 of the push-up machine 5
When taking out the partition plates 1 stacked on the tray 1 one by one from above, first raise the pusher 5, turn the handle 41, and lift the belt 37 until the top partition plate 1 is slightly lower than the center of the pulley 26. Adjust the reaction force so that it is about 325 g, and position it so that the upper limit position detection sensor 40 attached to the left side of the guide plate 2 is activated at that position.

Next, while driving the belt 37 in the direction of the arrow 37a with the electric motor 27, the suction pad 4 is lowered to attract the uppermost partition plate 1a, so that the second partition plate l is simultaneously attracted by the force of the belt 37. It is separated without being folded, lifted, or bent, and does not fall into the surroundings when being transported to the next process.

In the above embodiment, the partition plate 1 is made of cardboard, and the pressing force applied to the belt 37 is also specified.

The material may be polyester film, for example, and the belt 37
The pressing force and circumferential speed may be set to appropriate values by adjusting the handle 41, gears 28, 29, and pulleys 26A, 26B depending on the material, size, shape 1, bending rigidity, etc. of the plate material.

〔Effect of the invention〕

As described above, according to the present invention, in the plate material take-out device that sequentially takes out the plate-like workpieces picked up in the guide part on the push-up machine from the top and supplies them to the next process, the side surface of the uppermost workpiece is wound around the pulley. A belt is provided that rotates downward when the terminal end of the semicircular part is pressed, and when the topmost workpiece is taken out, it is separated from the second and subsequent workpieces, so that the plate material can be taken out one by one from the top. You can get the equipment.
