Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is disclosed in U.S. Patent Application No. 346, filed March 30, 1973.
The present invention relates to a rotary sorter including a plurality of laterally spaced sorting blades of the type generally disclosed in No. 337, ``Separator''.

Conventional rotary sorting blades are usually disc-shaped and have a smooth outer periphery, and these conventional sorting blades or sorting wheels generally meet their intended use.

However, there is a drawback in that slippage or motion stoppage often occurs between the cut scrap material and the periphery of the blade, and this slippage reduces efficiency. Moreover, the interaction between the sorting wheel and the waste material sometimes resulted in damage to the final product. The present invention relates to a rotary sorting device used in a sorting machine, and relates to a structure that improves sorting efficiency. An object of the present invention is to provide a novel rotary sorting device that automatically sorts sheet materials cut into shapes in advance.

Another object of the invention is to provide a novel sorting blade that applies frictional force to the waste portion of pre-cut material.

Another object of the present invention is to provide a novel rotary sorting wheel having a plurality of semicircular recesses bored in its outer periphery for effecting contact action.

Yet another object of the present invention is to provide a novel rotary sorting wheel in the form of a disc having a knurled surface on its outer periphery for effecting contact action.

Still another object of the present invention is to provide a novel rotary sorting wheel in the form of a disk, which has a plurality of recesses formed at appropriate intervals on its outer periphery, and the remaining portion has a jagged surface.

The rotary sorting wheel of the present invention incorporates a general disc-shaped rotary blade or ring, positions its outer periphery in contact with a waste portion of pre-cut material, and rotates a plurality of sorting blades or wheels simultaneously during sorting operation. It is located on the separation wheel set.

These rings are easily adjustable laterally along the axis,
It is possible to arrange a sorting wheel at each connecting part of the waste material of the cut sheet material, and an appropriate number of sorting wheels are arranged in the longitudinal direction at each connecting part of the cut sheet material to separate the final product and the waste material. automatically separate the The cut sheet materials are respectively supplied to the sorting section of the sorting machine and conveyed to the squeezing section of the input roller.

The sorting wheel is located behind the input roller and has a diameter approximately 25% larger than the diameter of the input roller. The axis of the sorting wheel is located on the sorting machine mutually with the narrowing part of the input roller, and a part thereof extends from the horizontal plane of movement of the cut sheet material conveyed to the sorting part. When the sheet material is supplied to the sorting machine, the separated final products are taken out from between the sorting wheels by the propulsive force of opposing rollers in the sorting section.
The waste portion of the cut sheet material comes into contact with the sorting wheel via a pre-formed longitudinal connection path and is forcibly redirected either below or above the transport surface of the final product. A plurality of laterally spaced downward (or upward) protrusions on the outer periphery of the sorting wheel eject waste material downward (or upward) from the final product transfer surface, and the waste material is then guided out of the sorter. Will be discarded. A plurality of recesses, preferably semicircular recesses, are formed at intervals on the outer periphery of each rotary sorting wheel, and the spaces between the recesses are provided with many irregularities or other suitable jagged surfaces.

These jagged surfaces or recesses work together to improve the efficiency of contact sorting, forcing the waste material downwards (or upwards) from the final product transfer surface in the sorter. When separating the cut parts from cardboard, etc., it is important that the speed of the sorting wheel is higher than the speed of the cardboard, etc. being transported.
In this way, the rotational speed of the separation wheel is adjusted such that the waste material is separated from the final product by its frictional force, thereby improving the separation efficiency. For example, it is most advantageous for the circumferential speed of the sorting wheel to be between 1.1:1 and 3:1 or 4:1 relative to the transport speed of the sheet material. Increasing the speed of this sorting wheel brings some of the recesses in the outer circumferential surface into contact with the waste material and also provides a vibration effect, which helps to separate the waste material from the final product. Further, one embodiment of the present invention will be described based on the drawings.
In the illustrated example, the sorter 10 has a supply conveyor 12 that transfers sheet materials 20 cut into shapes in advance to a sorting section 14, and after sorting in the sorting section 14, the sorted final products 2 are carried out to a conveyor 16. and then to a suitable stacking mechanism for transport to the end user.

The pre-cut sheet material 20 is fed to a conventional feeding mechanism 2.
5 to the supply conveyor 12, but side rollers may be provided as appropriate. A pair of adjustment guides 24 and 26 extending in the longitudinal direction and spaced apart in the lateral direction are arranged on the supply conveyor 12 to horizontally align the cut sheet material 20 being transported in the four directions of the sorting section. The waste conveyor 18 conveys the waste material 19 separated from the sheet material 20 by the action of a rotary sorting wheel 36 to be described later, and a curved baffle plate 38 for guiding the waste material 19 may be attached to the waste conveyor 18. The sorting section 14 is located immediately after the supply rolls 12 and is provided with conventional laterally spaced bearing mechanisms for supporting the roller axles 42, 44, 46, 48, 50, 52 and the sorting wheel axle 40, and further separates the The portion 14 includes each drive shaft 44,

The diameter of the rotary sorting wheel 36 is preferably larger than the diameters of the driving and driven rollers, and for example, the ratio may be 4:3. The shaft 40 of the sorting wheel is supported by bearings 2J8 and 30 such that the bottom peripheral edge 72 of the sorting wheel 36 is appropriately located below a plane that crosses the narrowed portions 60, 68, and 70 formed between the opposing rollers. , the lower peripheral edge 72 of this sorting wheel 36
The waste material separated from the die-cut sheet material 20 by means of the above-mentioned method causes the waste material to be redirected as indicated by the arrow 76 in FIG. 3 below the transport surface. The rotational peripheral speed of the peripheral edge 74 of each sorting wheel 36 is the same as that of the sorting machine 1.
The rotation of the shaft 40 of the sorting wheel is set to be higher than the speed of the sheet material 20 passing through 0, which causes the rotation of the shaft 40 of the sorting wheel to
Even if the speed is the same as that of 2, it can be achieved by making the diameter of the sorting wheel larger than the diameter of the driving and driven rollers, and the drive roller shafts 44, 48, This can also be achieved by using rotational speeds greater than 52 degrees.

As shown in FIG. 1, each die cut sheet material 20 has the shape of an arbitrary final product 21 divided in advance by die cutting or other method.
The remainder of the 21 parts of the final product is waste material 19, and the separator 10
It is tearfully eliminated by the operation of.

The final products 21 are arranged longitudinally in rows 78. Between the finished product rows 78 are spaced longitudinally extending rows 80 of waste material, preferably about one-half inch in width. Also, a suitable number of sorting wheels 36 are laterally spaced apart along their axis 40 such that one sorting wheel 36 is located in the longitudinal arrangement of each scrap row 80. ing.
