JPH05155423A - Posture correction device of truncated cone shaped object - Google Patents

Abstract

PURPOSE:To correct its posture while transferring a truncated cone shaped object by arranging a pair of transfer shafts in parallel so as to slant in one side and reversing them simultaneously and also setting the interval between respective transfer shafts larger than the outer diameter of the gravity center position of the truncated cone shaped object to be placed therebetween. CONSTITUTION:A pair of transfer shafts 3 (a, b) are reversed mutually toward the outside respectively and simultaneously through a pair of gears 9 (a, b) by a motor 8. A truncated cone shaped object A is changed between respective transfer shafts 3 so as to be transferred while correcting its posture. Meantime, as the interval X of the peripheral surfaces of respective transfer shafts 3 is larger than the outer diameter of the gravity center position of the truncated cone shaped object A and smaller than the outer diameter Y of its bottom surface, the small diameter side of the upper surface of the truncated cone shaped object A is turned downward and hung down between respective transfer shafts 3. As the ring shape recessed part 7 sides in one end side of respective transfer shafts 3 are slanted so as to become low, the truncated cone shaped object A is transferred to one side smoothly by the action between this slant and a screw 6 formed on the one transfer shaft 3a.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for correcting a truncated cone-shaped object transferred in a random posture to a posture in which the bottom surface thereof is upward, and sending it out. A truncated cone shape that allows the test sample mass (conical trapezoidal shape) extracted from the blast furnace for component analysis during the production process to be automatically adjusted in its posture so that it can be introduced into the pneumatic tube in a predetermined direction. The present invention relates to a posture correction device for an object.

[0002]

2. Description of the Related Art Generally, in a steel mill or the like, a toast sample of iron melted by a ladle or the like is extracted from the inside of a blast furnace for component analysis, and a lump (frustum-shaped object) of this test sample is usually separated from the blast furnace. It is pressure-fed by a pneumatic tube to an analysis room provided in a different place. In order to smoothly feed the test sample block, it was necessary to insert the test sample in the shape of a truncated cone into the pneumatic tube with the small diameter surface (upper surface) side facing forward.

Therefore, conventionally, a test sample extracted from the blast furnace with a ladle or the like is taken out from the ladle, and a lump of this high-temperature test sample having a truncated cone shape is manually inserted into an air feeding pipe by using fire chopsticks or the like. Was prepared, inserted and pumped. However, it is very irrational to manually adjust the direction of insertion of the test sample mass into the air feeding tube, which is performed 100 times or more a day, and the test sample mass is at a high temperature. Was very dangerous on. Therefore, automation of this work was also desired in the steel industry.

Therefore, the same person as the inventor of the present application developed a posture correcting device for a truncated cone-shaped object as disclosed in Japanese Patent Application No. 2-49023 previously filed to solve the above problems. It was However, in the case of this posture correction device, since a pair of transfer shafts forming a convex spiral line are horizontally arranged side by side with a predetermined interval, the larger diameter of the truncated cone-shaped object for transfer and posture correction is obtained. , 2 of the convex spiral strip on one of the transfer shafts
When it is placed on a mountain and the one with the smaller diameter comes to be transferred while being mounted on one mountain of the other convex spiral line or between mountains, it is said that the shape of the truncated cone cannot be corrected. Problem has occurred.

[0005]

Therefore, the inventor of the present application
Various studies have been made in view of the above points, and the present invention has been developed. The object of the present invention is to make a truncated cone shape capable of correcting the posture of a truncated cone shape object while smoothly and reliably transferring. An object is to provide a posture correction device.

[0006]

The present invention has the following constitution in order to achieve the above object. That is, an annular recess is formed in the vicinity of opposite ends of a pair of side-by-side transfer shafts, both shafts are rotatably mounted on a mount at a predetermined interval, and both shaft ends on the side of the annular recess are connected to the other shafts. Both shafts are arranged side by side so that they are lower than the ends and inclined in one direction, and the large-diameter end portion of the truncated cone-shaped object placed between these shafts is supported by both shafts. The distance between the annular recesses of the opposite shafts is larger than the large-diameter end dimension of the truncated cone-shaped object, and both the shafts are rotated in reverse synchronously by the driving means to transfer the truncated cone-shaped object. It is also a configuration capable of correcting the posture, and is a configuration in which a spiral line is formed on the outer peripheral portion of at least one of the pair of transfer shafts,
Further, the pair of side-by-side transfer shafts is a shaft that does not form a spiral line.

[0007]

With the above structure, the truncated cone shaped object moves smoothly due to the unstable balance of the center of gravity of the truncated cone shaped object and the rotation of both the axes because both transfer shafts are inclined. The small diameter portion (upper surface) faces downward due to the weight balance of the truncated cone-shaped object itself between both shafts. This truncated cone-shaped object is transported with its large diameter end portion being supported by both shafts. Further, when the truncated cone-shaped object reaches the annular recesses of both shafts facing each other, the distance between the annular recessed portions of both shafts is larger than the trapezoidal end dimension (bottom surface dimension) of the truncated cone-shaped object. As described above, the shaped object falls with the small diameter portion facing down.

Further, when a spiral line is formed on both of the transfer shafts, or when a spiral line is formed on one of the transfer shafts, the frustoconical shaped object has an inclination of both transfer shafts and a spiral line of the transfer shaft. Is transferred forward, and during transfer, the frustoconical shaped object is smoothly transferred due to the unstable balance of the center of gravity and the rotation of both shafts. The small diameter portion (upper surface) faces downward between the two shafts due to the weight balance of the truncated cone-shaped object itself. This truncated cone-shaped object is transported with its large diameter end portion being supported by both shafts.
Further, when the truncated cone-shaped object reaches the annular recessed portions of the opposite shafts, the distance between the annular recessed portions of both shafts is larger than the trapezoidal end dimension (bottom surface dimension) of the truncated cone-shaped object. As described above, the object drops with the small diameter portion facing down.

[0009]

Embodiments of the present invention will be described below with reference to FIGS. 1 is a posture correction device for a truncated cone-shaped object A according to an embodiment of the present invention, which is a pedestal 2 and a pair of transfer shafts 3.
It is composed of a and 3b and driving means. More specifically, plates 4a and 4b that pivotally support the transfer shaft 3 are erected on opposite sides of the gantry 2 so as to face each other so that the transfer shaft 3 is inclined in one direction as shown in the figure. Yes,
The plates 4a, 4b are provided with holes 5 for mounting the pair of transfer shafts 3 at predetermined intervals.
It is drilled at a position opposite to. And each transfer shaft 3
Both ends of a and 3b are inserted into these holes 5, and a shaft end on the side of an annular recess 7 described later is rotatably supported by both plates 4a and 4b so as to be lower than the other end. This both axes 3
The distance X between the outer peripheral surfaces between a and 3b is set to be slightly larger than the outer diameter dimension of the circular cross section at the center of gravity of the truncated cone-shaped object A and smaller than the bottom surface outer diameter (large diameter Y).

A spiral strip 6 is formed on the outer peripheral portion of the one transfer shaft 3a as shown in the figure. The spiral strip 6 is formed so as to incline toward the plate 4a from the outside to the inside when viewed from above the transfer shaft 3a. Further, although the spiral strip 6 of this embodiment is the projection 6a which is formed so as to be raised from the outer peripheral surface of the transfer shaft 3a to the spiral strip, the spiral groove 6 formed in the spiral line on the outer peripheral surface of the transfer shaft 3a may be formed. Good.

However, the two transfer shafts 3a and 3b have
When provided on the gantry 2, annular recesses 7 are formed at opposing positions near the plate 4a side. That is,
Annular recess 7 formed near one end of each transfer shaft 3a, 3b
Is formed so as to be curved inward by gradually reducing the diameter from both ends of each transfer shaft 3a, 3b. And these two transfer shafts 3
When a and 3b are provided on the gantry 2 at a predetermined interval as described above, the distance V between the annular recesses of the opposing shafts 3a and 3b is set to be larger than the large diameter end dimension Y of the truncated cone-shaped object A. is there. As a result, the transferred truncated cone-shaped object A falls from between the annular recesses.

A pair of transfer shafts 3 provided on the gantry 2
In this embodiment, one motor 8 and two gears 9a and 9b are used as the driving means for rotating a and 3b. That is, one end of the transfer shaft 3a on the plate 4a side is connected and fixed to the motor 8 provided outside the plate 4a. The other end of the transfer shaft 3a and the end of the transfer shaft 3b are projected from the plate 4b, and gears 9a and 9b are fixed to the plates 4a and 9b, respectively.
9b are in mesh with each other. Therefore, both transfer shafts 3a, 3
b is rotated in the opposite direction by the rotation of the motor 8.

A hole 11 having a diameter larger than the outer diameter of the bottom of the truncated cone A is formed in the bottom plate 10 between the annular recesses 7 of the transfer shafts 3a and 3b. 1
2 is fixed.

Next, a usage state of the truncated cone-shaped object posture correcting device 1 having the above-described structure will be described. First, the motor 8 is driven to simultaneously reversely rotate the transfer shaft 3a and the transfer shaft 3b via the gears 9a and 9b. At this time, the transfer shafts 3a and 3b rotate outward.
In this state, when the truncated cone-shaped object A having a random posture is dropped between the transfer shafts 3a and 3b, the outer peripheral surface distance X of the transfer shafts 3a and 3b is larger than the outer diameter of the truncated cone-shaped object A at the center of gravity position. Since it is large and smaller than the bottom surface outer diameter Y, the truncated cone-shaped object A does not drop downward and is suspended between the transfer shafts 3a and 3b with the upper surface (small diameter side) facing downward.

Since both transfer shafts 3a and 3b are provided so as to be inclined toward the annular recess 7 side as described above, the transfer shafts 3a and 3b are rotated and the transfer shaft 3a is rotated. Since the spiral projection 6a is rotating, the truncated cone-shaped object A is smoothly transferred to the plate 4a side by the action of the spiral projection 6a along with the sliding of its own weight due to the inclination. When the truncated cone-shaped object A is transferred to the positions of the annular recesses 7 of both shafts 3a and 3b, the truncated cone-shaped object A drops from the transfer shafts 3a and 3b and the holes 11 are formed.
And, it will be delivered downward through the guide tube 12.

The present invention is not limited to the above-mentioned embodiment, and it is not necessary to form spiral lines on the outer peripheral portions of both transfer shafts, or spiral lines may be formed on the outer peripheral parts of both transfer shafts. .. The design of the driving means may be changed in various ways.
Further, a baffle plate 13 is arranged above the intermediate portion of the transfer shafts 3a and 3b, and the posture of the truncated cone-shaped object A transferred by the transfer shafts 3a and 3b is controlled by the baffle plate 13. The posture may be positively corrected by the contact of the.

Further, a vibrator 14 may be installed on the gantry 2 to vibrate the gantry 2 so that the attitude of the truncated cone-shaped object A transferred by the transfer shafts 3a and 3b can be controlled by the vibration of the vibrator 14.

[0018]

As is apparent from the above description, according to the present invention, the pair of transfer shafts are arranged so as to be tilted low in the transfer direction. Due to the rotation of the shaft and the weight balance of the truncated cone-shaped object itself, the bottom surface (large diameter side) of the truncated cone-shaped object is surely turned upward during the transfer. Moreover, the truncated cone-shaped object is smoothly transferred by the inclination of the transfer shaft in the transfer direction and the action of the spiral stripes of both rotating transfer shafts.

Further, by forming a spiral line on one or both outer peripheral portions of both transfer shafts, the truncated cone-shaped object can be transferred more reliably. Therefore, the truncated cone-shaped object randomly placed between both shafts is automatically and surely corrected and transferred without manpower. Furthermore, when the truncated cone-shaped object reaches the annular recess near the ends of both shafts, the distance between the annular recessed parts of both shafts is set to be larger than the bottom surface (large diameter end) of the truncated cone-shaped object. Then the truncated cone is dropped.
