Abstract

PURPOSE:To make it possible to distribute powdery or granular body, etc. from a feeder in the form of fixed width and uniform thickness by using a mechanism in which a slider, engaged with the groove of a cam, is reciprocated by the rotation of the cam, then the main frame of the feeder, connected to the slider, is oscillated. CONSTITUTION:A cylindrical cam 11, turnably supported in a housing 8 by bearings 12, 13, is rotated by a driving device 14. Then, a click 23, engaged with the groove 15 of the cam, is slide and a slider 18, to which the click 23 is fixed, is slide along a guide rod 20. Consequently, a roller 33, is installed on the top of the slider 18, is moved and the main frame 5 of a feeder A, which has a long hole 34 coupled with the roller 33, is oscillated around a vertical shaft 4 at a uniform speed. Accordingly, when powdery or granular body, etc. is supplied on the rear portion of the belt conveyor 6 of the feeder A, the powdery or granular body can be distributed uniformly from the front end of the belt conveyor 6 to the lower net conveyer, etc. covering overall width of them.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oscillating feeder device for dispersing and feeding raw materials such as granules and powders over a constant width.

One of the known oscillating type feeders is one that uses a crank action to cause the feeder body to oscillate.

In this type, the crank driven by a motor and the feeder body are connected using a connecting rod, etc., but as is well known, the fast rotational movement of the crank is controlled by the connecting rod. When converted into motion, an object moving forward and backward becomes inuniform motion.

Therefore, if the feeder main body is oscillated by such a rank mechanism, the oscillation speed will not be constant throughout the night, and the raw material will be discharged unevenly from the tip of the feeder.

The technical problem of this invention is to make the oscillation speed of the feeder main frame uniform over the entire IJ in a feeder device, and the technical means provided for this purpose are as follows: The rear part of the main frame of the feeder, in which the belt conveyor driven by A reciprocating spiral endless cam groove is provided on the outer periphery of the cam, and a pawl that engages with this cam groove is provided.
A sliding body is provided that performs linear reciprocating motion parallel to the axis of the cam as the cam rotates, and this sliding body and the feeder main frame shown in 11; This is how they were engaged.

The operation of the above technical means is as follows.

When a cam with a cylindrical circumferential surface rotates at a constant speed, Y
The slider engages with a reciprocating spiral endless cam groove on the circumference, or moves reciprocally with a thread path parallel to the axis of the cam, or by keeping the pitch of the cam groove almost constant, the slider can be Performs constant speed linear motion.

This upper sliding body is connected to a long hole and a roller that fits into this long hole at a part of the feeder main frame on the side of the swing center, so the feeder main frame swings at an almost constant speed. Do exercise. Therefore, raw materials such as powder and granules are supplied from the tip of the feeder to the next conveyor with a constant width and almost uniform thickness.

Hereinafter, the details of this inventive device will be explained based on an embodiment shown in the accompanying drawings.

The figure shows an example in which the feeder device of the present invention is attached to an aerated drying device. 1 is a drying chamber, 2 is a net conveyor running inside the drying chamber, and both ends of the net conveyor protrude from the front and rear of the drying chamber 1.

Reference numeral 3 denotes a frame supporting the drying chamber 1, on the rear end of which is provided an oscillating type feeder device A of the present invention. Figure 3,
4 in FIG. 4 is 1 ql+ vertically on the frame 3, and the main frame 5 to the feeder device is attached to this vertical shaft 4 so as to be swingable.

A belt conveyor 6 is provided within the main frame 5, and this belt conveyor is driven by a drive device 7 consisting of a motor and a speed reducer.

8 is a machine box fixed on the rear part of the frame 3, and this machine box 8
Inside, as shown in Figures 5 to 7, a horizontally cylindrical cam 11 is provided, and the horizontal shafts at both ends of the cam 11 are connected to bearings 12 at both ends of the machine box.
, 13+ are rotatably supported.

Reference numeral 14 denotes a drive device for the cam 11, which is composed of a motor and a speed reducer, and its output shaft is coupled to the shaft of the cam 11 that protrudes from the bearing 12.

The outer peripheral surface of the cam 11 is a cylindrical surface concentric with its rotation center, and a reciprocating spiral endless cam groove 15 is provided on the outer peripheral surface.

Reference numeral 18 denotes a sliding body, into which the cam 11 is fitted in a horizontal hole 19 so as to be rotatable and slidable. In addition, 20 is a guide rod fixed in the machine box 8 so as to be parallel to the cam 11.
f) It is slidably fitted into a guide hole 21 provided in the sliding body 18 to prevent the sliding body 18 from rotating.

An opening 22 reaching the horizontal hole 19 is provided on one side of the sliding body 18, and a boat-shaped pawl 23 that slidably engages with the cam groove 15 is fitted into the opening 22. This claw 23 is integral with a short shaft 24, and this short shaft 24 is rotatably fitted into a cylindrical portion 26 inside a lid 25 which is closed by screwing the opening 1'' 22, as shown in FIG. .

Reference numeral 27 in FIG. 7 is a metal fitted between the cylindrical portion and the short shaft 24.

A horizontally elongated hole 31 as shown in FIGS. 3, 5, and 6 is provided in the top wall of the machine box 8, and a vertical shaft 32 provided on the sliding body 18 is loosely fitted into the elongated hole 31. A roller 33 that rotates around a vertical axis is mounted on the shaft 32 that protrudes in the second direction.

Further, as shown in FIG. 3, the rear main frame 1 of the main frame 5 of the feeder l\ is provided with an elongated hole 34 in the front-rear direction.
Attach the roller 33 to 4.

10. In the configuration shown in FIGS. 3 to 7 above, when the cam 11 is rotated at a constant speed and in a constant direction by the drive device 141, the pawl 23 that is engaged with the cam groove 15 is The sliding body 18 to which the pawl 23 is attached slides against the guide rod 20.

Therefore, as the cam 11 rotates, the sliding body 18 moves toward the guide rod 2.
0, and the roller 33 above it also moves at a constant speed.

When the roller 33 moves at a constant speed as described above, the main frame 5 having the elongated hole 34 into which it is fitted also performs a uniform swinging motion about the vertical axis 4.

Therefore, in the case of the embodiment shown in FIGS. 1 and 2, a raw material such as powder or granules is supplied in a fixed amount onto the rear part of the belt conveyor 6 of the feeder A from the raw material supply conveyor (not shown), and the belt conveyor 6 and the cam 11, the raw material at a constant distance from the tip of the belt conveyor 6 is uniformly supplied all over the rear part of the net conveyor 2. When hot air is blown from the hot air blower 1'' 9 on the side of the drying chamber 1 while driving in the direction of the arrow, the raw material on the conveyor 2 is dried and discharged from the product extraction/neat 10, and the moist air after drying is sent to the drying chamber. 1 is extracted from the exhaust port 16 on the top.

In this case, by using the feeder device of the present invention, the raw material is evenly placed on the net conveyor 2, so that drying can be done uniformly.
