Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a stone polishing apparatus.

[0002]

[Prior art]

 An old type of equipment that grinds stones by rolling the stones inside the rotating drum while rotating the rotating drum with the stones supported horizontally, and dropping the corners. In the case of, the rotating drum carries in or out of the stone by itself in the posture at the time of polishing, or does not block the loading / unloading port of the rotating drum filled with the stone. When the stones are thrown into the rotating drum, there is no means to prevent the stones from escaping outside through the loading / unloading port of the rotating drum. In this state, it was put in through the inlet / outlet, and the inlet / outlet was closed with an opening / closing lid, and the polishing work was performed while the rotating drum was turned sideways and rotated. When the work is completed, the rotating drum is erected again, the opening / closing lid is removed from the loading / unloading port, and the loading / unloading port is tilted upside down to discharge the polished stones. It was very troublesome.

[0003] Thereafter, a guide means is provided at the loading / unloading port of the stones of the rotary drum so that the stones can be loaded or unloaded by itself in relation to the rotation direction of the drum. All operations such as charging, polishing, and discharging are performed in the same posture with the rotating drum arranged horizontally, and an economical polishing apparatus that does not require complicated structure and operation can be used. The guide means is such that a liner is attached to the inner surface of the rotary drum, and the liner is provided so that, when the liner is continuously arranged, the ridges provided in advance are spirally continuous. The spiral is formed on the inner surface side of the rotating drum by attaching the liner on the inner surface side from the input / output port to the bottom side. When the spiral is rotated to advance to the bottom side, the stones loaded are transported to the bottom side and rolled at that position until the rotation is stopped and polished. In this case, even if the rotary drum is horizontal and the inlet / outlet is not closed, the spiral can advance to the back side in the rotation, so that stones can be prevented from jumping out. After that, the screw on the bottom side can be discharged from the inlet / outlet by turning the spiral backward and screwing it back to the inlet / outlet side. In this conventional spiral, the helical angle is set to be small near the inlet / outlet of the rotary drum and to be larger than the position where the polishing is performed, that is, the vine angle is larger at the bottom side. It was.

[0004]

[Problems to be solved by the invention]

 However, in this conventional stone polishing apparatus, the spiral provided on the inner surface of the rotary drum has a large helical angle of the polishing section and a large feed amount per rotation. There was a problem that it was not possible to roll smoothly in the same place and the discharge could not be performed smoothly. In addition, although a spiral is formed by attaching a liner to the inner surface of the rotating drum, the type of liner is increased because the liner is not provided so as to continuously form the spiral by minimizing the type of liner. In addition, there was a problem that many liners had to be prepared for maintenance at a later date, which was disadvantageous in terms of cost and management.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to make it possible to smoothly and continuously perform the steps of charging, polishing and discharging stones, and to provide a spiral body. An object of the present invention is to provide an apparatus for polishing stones that can economically form stones.

[0006]

[Means for Solving the Problems]

 As a means for solving the above-mentioned object, in the stone polishing apparatus according to claim 1 of the present invention, a bottomed cylindrical rotary drum having an inlet / outlet for stones at one end and a rotary drum having the same are provided. It has a gantry that supports it sideways and a rotating device that rotates the rotating drum in the forward and reverse directions. Inside the rotating drum, stones introduced from the loading / unloading port by the forward rotation of the rotating drum are placed at the bottom. A spiral body is provided to guide the stones toward the loading / unloading port by guiding the stones in the depth direction and reversely rotating them.The spiral body has a plate-shaped liner having a ridge on its surface inside the rotating drum. In a stone polishing apparatus formed by sticking a large number on a peripheral surface, the spiral body gradually advances the arrangement of the ridges in one direction to form a plurality of sets of liners provided at different positions. Repeated distribution As a result, the same helical angle is provided from the inlet / outlet to the bottom, and each of the liners is formed in a rectangular shape of the same size and has a bolt assembly hole at the same position on the surface. In addition, the bolt assembling hole is provided with a hexagonal hole-shaped counterbore that serves as a stop around the bolt and protects the bolt head on the front surface side.

The stone polishing apparatus according to claim 2 is characterized in that in the stone polishing apparatus according to claim 1, the spiral body is screwed into two or more threads.

In the stone polishing apparatus according to the third aspect, in the stone polishing apparatus according to the first or second aspect, the plurality of sets of liners are continuously arranged in a predetermined order up to a liner at a predetermined position. After the arrangement, the helical body of a fixed length is formed by rearranging the liner portion of the continuous arrangement in reverse order following the liner at the predetermined position, and reversing the liner portion in a state where the left and right positions are reversed. It is characterized by.

[0009]

[Action]

 In the stone polishing apparatus according to claims 1 and 2 of the present invention, the spiral body provided on the inner surface of the rotary drum is such that the helical angle at the bottom is the same as the helical angle at the input / output port. Has become. Therefore, although the feed amount of the spiral body by one rotation of the rotary drum is smaller than the spiral angle of the spiral body at the bottom part which is larger than the spiral angle at the input / output port, the actual feed and discharge performance is good. In this way, efficient work can be performed comprehensively. When the number of the spirals is two or more, the spirals become denser, which works well for polishing stones, and can be fed more smoothly.

[0010] The spiral body on the inner surface of the rotary drum is formed by attaching a liner. However, if a plurality of sets of liners are repeatedly arranged, the spiral body can be formed continuously, so that the number of types of liners can be reduced.

In the stone polishing apparatus according to the third aspect, since the same liner is used by inverting left and right in the plurality of sets of liners, the types of the liners can be further reduced. By reducing the number of liners, assembly and parts management can be facilitated and quality can be improved.

In the figure, reference numerals 14 and 15 denote spiral bodies which are screwed out of phase on the inner surface of the rotating drum 13 and have a helical winding angle that makes 5 rotations from the inlet / outlet port 25 to the bottom wall 26 respectively. Is provided. The spirals 14 and 15 are both formed by attaching a liner R to the inner surface of the rotating drum 13. FIG. 3 is an exploded view of the entire liner attached to the inner surface of the rotary drum 13. Since the liner is repeated only in the same direction in the longitudinal direction of the body, the liner is omitted for the sake of space. In the case of the present embodiment, ten liners are arranged in the circumferential direction, and the liners are arranged in ten rows in the depth direction so as to cover the entire inner surface. A liner having a ridge 16 with narrowed upper surfaces and angular shoulders on both sides is arranged so that feeding can be reliably performed for the amount that the spirals 14 and 15 rotate about 1.5 times. A liner having a smooth ridge 17 without corners is arranged so that any surface of the crushed stone can be easily polished.

More specifically, in the case of the present embodiment, as shown in FIG. 3, both the liner having the sharp ridge and the liner having the smooth ridge are each a ridge. Of three different shapes in which the position of_A , R_B , R_C And R_D , R_E , R_F Are prepared.

When the spiral bodies 14 and 15 have been wound for about 1.5 turns, the liner R_D , R_E , R_F Are continuously arranged in the same manner as above. The inverted liner has the sign R_e , R_d Indicated by

FIG. 4 is a plan view showing the liner _RA , FIG. 5 is a right side view thereof, FIG. 6 is a sectional view taken along line AA of FIG. 4, and FIG. 7 is a sectional view taken along line BB of FIG. is there. Further, the liner R _B, R _C and R _D, R _E, FIG. 4 of the R _F, planar, cross-sectional structure corresponding to FIG. 6 are shown in FIGS. 8 to 12. In the drawing, reference numeral 18 denotes a bolt hole formed in all the liners R _{A to} R _F with a common pitch. Bolt assembly is performed on the entire outer wall material of the rotating drum 13 through bolt holes regularly arranged at the pitch. It is what you do. Reference numeral 19 denotes a counterbore that serves both to prevent the bolt from rotating and to protect the bolt head.

Next, the operation of the stone polishing apparatus of the present embodiment will be described. The rotary drum 13 is connected to the liners R _A , R _B , R _C in the circumferential direction as shown in FIG. 3 at the charging / discharging port 25, and then the liners R _b , R _a (the liners R _B , R R). _{The start end} of the first spiral 14 is created by connecting the first spiral 14. By connecting these five liners once again in the same order as described above, one round is formed, and the starting end of the second spiral 15 is created. Then, one line of the ten liners is arranged in three rows in the direction of the bottom wall. Then continue liner R _D, R _E, the end of the bottom wall portion 26 in helical angle as efficient for conveying the helix 14 and 15 of the two articles by arranging seven rows 10 sheet by sheet in the same manner the by R _F Part can be formed. In this embodiment, the helical body is set to make five turns (five rotations) with respect to the drum length of 5 m. In this case, the spiral bodies 14 and 15 are switched from a square shape to a smooth shape at a position of 1.5 turns from the start end side. In this case, a total of 100 liners are used, but a total of only six types of liners can be completed. Therefore, assembly can be performed very easily without any confusion, and there are only six types of stock for repairs at a later date, which is very economical.

Next, in use, after the rotating drum 13 formed as described above is installed, the driving tire 22 is driven by the drive motor 22 to rotate the rotating drum 13 in a horizontally supported state. . While the rotating drum 13 is rotating or stopped, crushed stones 24 are fed into a loading / discharging port 25 from a feeder (not shown). In this case, the rotating drum 13 is rotated so that the spirals 14 and 15 advance in the direction of the bottom wall 26, and the crushed stone 24 is conveyed while rolling along the spiral toward the bottom wall 26 until it hits an obstacle. . Therefore, the crushed stone 24 is polished while rolling at the position during the rotation of the rotary drum 13 after hitting the bottom wall portion 26 or the preceding crushed stone already hitting the bottom wall portion.

After a predetermined time has elapsed, when the drive motor rotates the rotary drum 13 in the reverse direction according to an instruction, the spirals 14 and 15 rotate in the direction of screwing back to the loading / unloading port 25, so that the crushed stone 24 is removed from the low wall portion 26 side. It is conveyed and discharged in the direction of the loading / unloading port. In this case, since the spiral body is formed primarily for efficient transport, the loading and unloading can be performed extremely smoothly, and the working time can be reduced and the cost can be reduced. . In addition, if polishing takes a longer time, a higher quality polished product can be obtained.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to the present embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Even this is included in the present invention. For example, the ridge shape of the liner, the basic number for combination, the number of repetitions, the total number of uses, and the like can be arbitrarily set. In the liner according to the embodiment, only the shape of the ridge is different. Therefore, the ridges may be used in combination, or the spiral may be provided only for one of the ridges. In addition, the helical angle, the number of turns, the number of turns, and the like of the spiral body can be arbitrarily set within a range in which conveyance or polishing is favorably performed.

[0022]

[Effect of the invention]

 In the stone polishing apparatus according to the first and second aspects of the present invention, the helical member provided on the inner surface of the rotary drum has the same helical angle at the bottom as the helical angle at the inlet / outlet portion. It is screwed at least one turn, and the feed amount per rotation of the rotating drum is smaller than that of less than one turn of the helical body, but the actual feed and discharge performance is good and overall efficiency is high. Work can be performed. Further, by making the helical body double or more, the helical body becomes dense and works favorably on the polishing of stones, and effects such as smoother feeding can be obtained.

The spiral body on the inner surface of the rotary drum is formed by attaching a liner. However, if a plurality of sets of liners are repeatedly arranged, the spiral body can be formed continuously. The effect is that it is possible to save money and increase the efficiency during manufacturing.

According to the third aspect of the present invention, the same type of liner is used by inverting the same liner in the plural sets of liners, so that the type of the liner can be further reduced. Reducing the number of types of liners facilitates assembly and parts management and improves quality.
