Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an apparatus for accommodating a desired number of plate-like objects that are continuously dropped and placed at a predetermined mutual interval and delivering them to the next process.

Below, the structure, operating method, and effectiveness of this device will be explained in detail with reference to the accompanying drawings.

The plate-like object 10, which is the object to be processed by this apparatus, is a flat plate with a specific size, but there may be some variation in the size. The upper surface may be such that the plate-like objects 10 further stacked thereon can be piled up in an aligned manner, and may have some degree of unevenness within that area. It is necessary that the lower surface be a smooth plane or almost a plane. Although this cannot be said unconditionally, depending on the thickness or weight of the plate-like object 10, the degree of vacuum adsorption, etc., the lower surface thereof may not necessarily be a smooth surface, but may be a somewhat rough surface.

The hopper 11 is for accommodating the plate-like objects 10 in a stacked manner and dropping them to the transfer mechanism 20 from the lower end, and hangs down perpendicularly to the belt 21 . Depending on the number of guides 25 and their positions, which will be described later, a partition frame 15 that is slightly wider than the guides 25 may be provided inside so that a plurality of plate-like objects 10 can be dropped simultaneously in the transverse direction of the belt 21. For example, in FIG. 1, the plate-like objects 10 are arranged in four rows, so the interior of the hopper 11 is also partitioned into four chambers. At the lower ends of both the left and right walls 12, 13 of the hopper 11, a plate-like object 10,
The height can be adjusted by cutting off a height corresponding to the thickness of about one and a half sheets or by using appropriate means, and a gap is provided. The lower ends of the partition frame 15, the front wall 14, and the rear wall are made to be the same as or slightly higher than the height of the top of the horizontal frame 23 so as not to obstruct the progress of the belt 21, which will be described later.

The transfer mechanism 20 has a timing belt 21 stretched around geared pulleys 31 and 32 at both left and right ends.

The belt 21 is connected to the pulley 3 since a timing belt is used to synchronize the operation of the device.
1 and 32 are also equipped with gears. belt 2
A horizontal frame 23 is provided in the transverse direction of the frame 1, and a recess 22 is provided between the horizontal frames. It is sufficient for the height of the horizontal frame 23 to be about half the thickness of the plate-like object 10. The recess 22 is a plate-shaped object 1
It is made slightly wider than the size of 0 to provide room for accommodating 10 plate-like objects. A punched hole 26 is provided in the recess 22, and the size is such that the suction cup 50 can be exposed upwardly through the punched hole 26. Therefore, continuous recesses 22 of the same number as the desired number of sheets are provided so that the desired number of sheets can be delivered as one group from this apparatus to the next process, and a horizontal frame 24 for empty feeding is provided thereafter. The height of the horizontal frame 24 for idle feeding may be the same as that of the horizontal frame 23, but its width is determined depending on the plate-like object feeding speed in the next process. In other words, the width is such that the desired number of sheets are stacked and delivered to the same place while the conveyor for the next process is intermittently moving forward, and the plate-shaped articles 10 are not supplied while the conveyor for the next process is in progress. shall belong to.

The belt 21 is attached to a receiving plate support shaft 28 that is fixed to the machine frame to prevent it from sagging or deforming due to its own weight.
It may be supported from below by a receiving plate 27 resting on the support plate 27 .

Note that a guide 25 that vertically divides the belt 21
are provided in a required number on the horizontal frame 23 according to the size of the plate-like object 10. The lower end thereof may be positioned so as to be in contact with the upper end of the horizontal frame 23, and may be fixed to the machine frame by appropriate means.

The transfer mechanism 20 may be driven by either the left or right pulley, but in FIG. 2, the right pulley 32 is a driving roll and the left pulley 31 is a driven roll.

The pulley on the discharge end side of the plate-shaped object 10, that is, the right pulley 32, has a special structure. That is, the pulley 32 is composed of two rolls stacked one on top of the other, an inner and outer fixed roll 33 having a hollow part 34 in the center, and an outer fixed roll 33 that is rotatably attached to the fixed roll 33. The rotary roll 37 is provided with a rotating roll 37. The shaft 42 of the fixed roll 33 is also hollow and communicated with a vacuum pump.
The rotating roll 37 and the fixed roll 33 are pivotally supported by the same bearing 40, and the fixed roll 33 can be fixed at any rotational position by a worm wheel 41. Worm wheel 41
is rotated by a manual rod 43 which is similar to a hand-cranked device.
The outer circumferential surface of the fixed roll 33 is cut into a groove shape over about half of its area or the entire area to provide a recessed part 35, and one to several passages 36 are provided in the area, and a hollow part 34 and a recessed part 35 are provided. The concave portion 35 is communicated with the concave portion 35 . On the other hand, the belt 2 is attached to the rotating roll 37.
A through hole 38 corresponding to the position of the first punched hole 26 is bored, and a cavity 39 is provided on the outer surface side of the through hole 38 to fit the suction cup 50 thereinto. The diameter of the rotating roll 37 is such that the belt 21 can accommodate the plate-like material 1 to be delivered to the next process in a stacked manner.
It is determined by the desired number of zeros. Needless to say, the outer circumferential length of the rotary roll 37 is small and must be longer than one cycle of co-feeding operation, so the recesses 22 and horizontal frames 23 for the desired number of sheets are
This is because it is necessary to take care that the total length of the blank feeding horizontal frame 24 does not exceed the outer circumferential length of the rotating roll 37.

The suction cup 50 has a funnel shape and is made of a resilient material, such as rubber. The size of the base 51 is made slightly larger than the empty space 39. The empty chamber 39 and the base 51 may have a reverse taper,
You don't have to wear it. The base 51 is press-fitted into the empty chamber 39.
A ventilation hole 52 is formed in the center of the hole.

Next, a method of operating the present device will be explained.

First, as a pre-process of this apparatus, a plate-like object 10 is fed to a hopper 11. It can be done either by continuous mechanical operation or by hand.

When the recess 22 of the belt 21 reaches directly below the hopper 11, the plate-like object 10 falls from the hopper 11 into the recess 22 due to its own weight and is accommodated. The next plate-like object 10 immediately below the fallen plate-like object 10 is blocked by the fallen plate-like object 10 and the lower end of the right wall 12, and cannot fall onto the recess 22, so that it accumulates in the hopper 11. Then, the next recess 22 is the hopper 1
When it reaches 1, it will fall into this and be contained. By repeating this operation, the desired number of sheets is continuously stored on the belt 2.
When the plate-shaped object 10 is taken out and sent to the right, the horizontal frame 23 for empty feeding reaches just below the hopper 11.
cannot fall and accumulates in the hopper 11.

On the other hand, in the right pulley 32, the hollow part 3
4 is kept under vacuum at all times and driven. The fixed roll 33 is fixed so that the concave portion 35 is located in the area corresponding to the tension of the belt 21, so while the rotating roll 37 is passing through that area, the passage 36, the concave portion 35, the through hole 38, the ventilation hole 52 (or The hollow portion 34 communicates with the atmosphere via the empty chamber 39). Of course, belt 21
In the non-stretched portion, there is neither the recessed portion 35 nor the passage 36, so that the hollow portion 34 is isolated from the atmosphere.

When the plate-shaped object 10 reaches this right pulley 32, the suction cup 50 fitted into the rotating roll 37 is fitted into the punched hole 26. If the concave portion 35 is provided so as to start at a position just before the belt 21 and the pulley 32 start contacting each other, suction of the plate-shaped object 10 seems to be performed more smoothly. That is, since the suction cup 50 which is already passing over the concave portion 35 is under vacuum action, it immediately suctions and suctions the plate-like object 10 through the punched hole 26 . The plate-shaped object 10 continues around the periphery of the right-hand pulley and reaches the lowest position of the pulley 32, where the concave portion 35 disappears, so that it separates from the suction cup 50 and falls to the next process.

If the operation of the next process is stopped while the desired number of sheets is being received, and the next process is operated while the empty feed horizontal frame 24 is passing directly above the next process, the desired number of sheets will be on the conveyor of the next process. The plate-like objects 10 will be accommodated in a stacked manner. However, if it is not necessary to accommodate the sheets in a stacked manner, the next step may be operated continuously and the sheets may be simply grouped into desired numbers and moved forward.

Here, as a specific example of the next step, a tray transfer device for stacking and storing a desired number of plate-like objects 10 can be considered. That is, it consists of a tray hopper 62 that accommodates a large number of trays 61, a tray take-out device 67, and a tray transfer device 68.

The trays 61 stacked in the tray hopper 62 fall and fit into the cam grooves 64 of the cam 63 that supports the four corners of the tray 61, and as the cam 63 rotates, it moves downward while remaining in the cam groove 64. When it reaches the lower end of the cam 63, it is released from the cam groove 64 and dropped onto a stopped conveyor. Of course, for this purpose, it is important to adjust the shape of the cam groove 64 and the rotation of the cam 63 so that the spirally bored cam groove 64 can always vertically lift the tray 61 on its rim 69. As a result, the tray 61 is connected to the hopper 6.
It will be guided and dropped from inside 2 directly below it.

By the way, the next tray 61 is the same as the previous tray 61.
The cam 63 dislocates after the rim 69 fits into the cam groove 64, so when it reaches the upper end of the cam 63, there is no cam groove 64 to fit into, so the cam 63 rotates once and the cam groove 64 moves again. Until it reaches directly below the tray 61, it remains at the upper end of the cam 63. In order to enhance the effect of preventing double tray supply, the rims 6 of two adjacent trays 61 are
It is effective to keep the trays 9 separated from each other, that is, to prevent the trays 61 from completely fitting together. However, this is not a new technique in the present application, since this is already commonly done from the standpoint of preventing blocking of the tray 61 (fitting and becoming difficult to separate).

The tray 61 that has fallen onto the conveyor 65 is pushed forward by the attachment 66. Therefore, it is preferable to use the index 60 to link this conveyor 65 with the apparatus of the present invention.

Since the apparatus of the present invention is as described above, the plate-like objects 10 can be safely and reliably divided into groups and sent to the next process, and the intermediate slipping can be carried out without causing cracks or chips in the plate-like objects. It is possible to perform various processing.
