Abstract

PURPOSE:To smoothly transfer an object to be delivered toward the vertical upper direction without shedding the object by the edge of a wing plate, by providing a cut portion by making the diameter of a supplying section of a spiral wing plate inserted axially into a transferring cylinder smaller than that of the other portion of the wing plate. CONSTITUTION:A transferring cylinder body 4 is constructured by a transferring cylinder body 1 provided with a discharge cylinder 2 and 2 supply cylinder 3 connected to the upper end portion of the cylinder 1 and the lower end portion of the cylinder 1, respectively. In addition, a spiral wing shaft 8 is constructed by a rotary shaft 5 provided in the transferring cylinder 4, being supported by bearing members 6 at its upper and lower end portions, and a spiral wing plate 7 consisting of a sheet of continuous band plate and secured to the outer circumferential surface of the shaft 5 over the whole length of the transferring cylinder 4. In this case, a supply port 9 is provided at the side wall of the supply cylinder 3, and a cut portion is formed by making the diameter of a part of said wing plate 7 corresponding to the height of supply port 9 smaller. Thereby, after the object to be delivered is dropped on the wing plate 7 spaced at one pitch lower from the cut portion 10, the object is, in turn, transferred upward following the rotation of the wing plate 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer device, and an object of the present invention is to provide a continuous spiral type transfer device that can transfer small articles vertically or at a near-vertical angle.

Conventional devices that vertically transport grains such as soybeans, adzuki beans, corn, and rice generally rely on the packet method, which involves moving and reversing a large number of packets attached to an endless belt or chain. Grain was being transported to different locations.

However, this method not only results in a structure in which objects to be transported are sent intermittently, but also requires space for the return route to send back empty packets, and has the problem of increasing the size of the device. Ta.

The present invention has been made in view of the above problems, and is configured so that a spiral type transfer device, which has conventionally been used only horizontally or on a gentle slope, can also be used in a vertical position. be.

That is, in the transfer device of the present invention, a notch portion having a smaller diameter than other portions is formed in the supply portion of the spiral blade shaft inserted into the transfer tube, and the supply port opened in the transfer tube is configured in a special shape. , the object to be transported is vertically transported by the rotation of the spiral blade shaft.

An embodiment of the transfer device of the present invention will be described below with reference to the drawings.

1 is a sawtooth cylindrical transfer cylinder body installed vertically;
A discharge tube 2 and a supply tube 6 are fitted and connected to the upper and lower ends of the main body 1, respectively, to form a transfer tube 4.

Reference numeral 5 denotes a rotating shaft which is inserted into the transfer tube 4 through bearing members 6, 6 fixed to each end member of the discharge tube 2 and the supply tube 6 so as to be rotatable. A spiral vane plate 7 consisting of one continuous band plate extending along the entire length of the transfer tube 4 on the outer periphery.
are screwed and fixed to form the spiral vane shaft 8 (consisting of -).

The outer diameter of the spiral slat 7 is the same as that of the main body 1. The discharge tube 2 and the supply tube have a slightly smaller diameter than the inner diameter of the tube, and rotate sufficiently close to the inner wall.

As mentioned above, the supply port 9 is opened in the side wall of the supply tube into which the lower end of the spiral blade shaft 8 is inserted, and the portion of the spiral blade plate 7 corresponding to the height of the supply port 9 is a quarter of the height of the spiral blade plate 7. A notch 10 is formed which has a small diameter over one pitch and allows the object to be transported to pass through between it and the inner periphery of the supply cylinder 6.

In addition, the supply port 9 has a horizontal upper edge 1 as shown in FIG.
1 and a leading edge 1 having an internal angle α of about 80 degrees with the horizontal upper edge 11.
2. A trailing edge 1 having an internal angle β of 90 degrees with the horizontal upper edge 11, and a semicircular lower edge continuous with the leading edge 12 and the trailing edge 16 and consisting of an arc with a diameter 1 smaller than the outer diameter of the spiral blade plate 7. 1
4, and connected to the supply port 9, the introduction tube 15 is provided so as to protrude from the supply tube 6 so that the lower part of the inner periphery is in contact with the semicircular lower edge 14.

Further, the discharge tube 116 opened on the circumferential side of the discharge tube 2 opens into a chute 17 protruding from the discharge tube 2.

In addition, 18 is a gooley attached to one end of the rotating shaft 5, and is drivingly connected to the j and % moving shafts of a motor (not shown) via an endless belt, and drives the spiral blade shaft 8 at an appropriate high speed. It is configured to be rotationally driven in the direction of arrow X.

The transfer device configured as described above rotates the spiral blade shaft 5 using a motor while transferring grains M q (7″) i U
; When the material to be transferred is transferred to a high place, for example, soybeans or the like is supplied to the introduction tube 15, the falling soybeans enter the transfer tube 4 from the supply port 9 and rotate in the direction of the arrow X. It is pushed upward by the spiral blade plate 7.

Since the spiral slat 7 has a notch 10 at the height of the supply port 9, the soybeans fed from the supply port 9 are blown away by the edges of the spiral slat 7. The soybeans fall onto the spiral blade plate 7 one pitch below from the notch 10 without being crushed. Therefore, the soybeans that have fallen onto the spiral blade plate 7 are affected by the spiral action of the rotating spiral blade plate 7 and the spiral blades. The soybeans are pushed up against the inner wall of the transfer tube 4 by the centrifugal force generated by the rotation of the plate 70, and the soybeans are successively pushed up along the inner wall, and are discharged from the discharge tube 16 at the top of the transfer tube 4 through the chute. It will be discharged after 17 days.

As described above, the transfer device of the present invention is capable of vertically transferring objects to a high place by using a simple structure in which the blade shaft rotates within the transfer cylinder, and also enables continuous transfer. The present invention has a feature that the transfer space is small and the device can be made more compact, and the practical effects of the present invention are extremely large.
