Abstract

PURPOSE:To make it possible to vertically convey substances to be conveyed to a high level place by providing a conveying device having such a very simple structure that a spiral plate shaft is rotated in a conveying cylinder together with the latter. CONSTITUTION:A conveying device has a rotating driven conveying cylinder 1 in which a spiral plate shaft 3 is disposed such that it rotates at a speed different from the speed of the cylinder 1, and due to the rotation of the conveying cylinder 1 the substances to be conveyed is transferred upward in association with the spiral plate 6. With this arrangement of the conveying device, the substances may be vertically transferred to a high level place by such a very simple structure that the spiral plate shaft 3 is rotated in the conveying cylinder 1 together with the latter, thereby the conveying space of the conveying device may be made small and as well the miniaturization of the device may be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device for conveying small articles vertically or upward at a steep angle close to vertically, and particularly provides a conveying device for continuous spiral strips for conveying articles with low frictional resistance. The purpose is to

Conventionally, endless bells (a) and packets (b
) is used, but this packet type requires a space (C) to send back empty packets, resulting in a larger device. A conveyance device that can save space has been desired.

The present invention has been made in view of the above problems, and is configured so that a spiral strip type conveying device, which has conventionally been used only horizontally or on a gently sloped section, can also be used in a vertical position. This is what I did.

That is, the conveying device of the present invention inserts a threaded band plate shaft having a rotation speed different from that of the conveying cylinder into a rotationally driven conveying cylinder, and simultaneously holds the conveyed object on the inner surface of the cylinder by the rotation of the conveying cylinder. The conveyed object is conveyed upward by the rotation of the spiral band plate.

An embodiment of the conveying device of the present invention will be described below with reference to FIGS. 2 and 3. (1) is a conveying cylinder which is installed in the vertical direction and is rotatable via a bearing device (2), and is installed in the vertical direction. A threaded band plate shaft (3) having the same axis is inserted into the conveying cylinder (1), and the threaded band plate shaft (3) has the same axis.
) is a device in which a threaded strip (6) consisting of a continuous strip of threaded strips is screwed and fixed to the outer circumference of a rotating shaft (5) whose both ends are rotatably mounted using bearings (4). The spiral strip plate (6) is inserted so that its outer edge rotates in close or sliding contact with the inner wall of the conveying tube (1), and extends to both ends of the conveying tube (1).

The conveyor cylinder (1) and the screw strip shaft (3) are connected to the motor (7).
A pulley (8) that is rotatably driven by
are rotatably connected via the bell (10), and the pulley (1) provided at one end of the rotating shaft (5) and the boot provided on the motor shaft are connected to the other V-bell (1). (+3) for rotational connection. The object to be transported is placed in the transport cylinder (1).
The centrifugal force accompanying the rotation in step 1) provides a rotational speed sufficient to hold the tube on the inner surface of the cylinder wall. In addition, the screw plate shaft (
3) is adjusted to rotate faster or slower than the conveying tube (1), and is controlled by the relative speed between the conveying tube (1) and the threaded strip (3) and the pitch of the threaded strip (6); will determine the speed.

In the figure, (14) is a conveyed object supply valve, and (I) is a conveyed object discharge gutter.

The conveying device with the above configuration uses a motor (force) to move the conveying cylinder (
1) and a spiral band plate shaft (3) are rotated to transport small mechanical parts, grains, and other powder-like objects to a high place in the vertical direction. When the conveyed object is put into the conveyed object supply valve (14), the conveyed object is transferred to the conveying tube (1) by the threaded band plate (6).
) At the same time, since the transport cylinder (1) is rapidly rotating, the object to be transported is pressed against the inner wall surface of the transport cylinder ( ) by centrifugal action, and rotates together with the transport cylinder (1). Begins to move. At this time, the threaded band plate shaft (3) is rotating with a difference in rotational speed relative to the conveying tube (1), so the threaded band plate (6 ) depending on the conveyor tube (1
) The object to be conveyed located on the inner surface of the tube (+) is conveyed upward by the thread effect and is ejected from the upper end of the conveyor cylinder (+).
The discharged object falls from the object discharge chute.

According to the above configuration, by changing the rotational speed of the rotating shaft (5), the relative rotational speed with the transport tube (+) can be freely changed, so the transporting speed can be freely adjusted. It is possible.

As described above, the conveying device of the present invention is capable of vertically conveying objects to high places by using an extremely simple structure in which the threaded band plate shaft rotates together with the conveying cylinder within the conveying cylinder. It has the characteristics that the transport space is small and the device can be downsized, and the practical effects after implementation of the present invention are extremely significant.
