DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] A method and device for filling powdered or granular material W according to an embodiment of the present invention will be described below with reference to the accompanying drawings. Note that the following description is essentially merely illustrative and is not intended to limit the present invention, its applications, or its uses.

[0012] Fig. 1 shows a plan view of a filling device 1 for powdered or granular material W according to one embodiment of the present invention. As shown in Fig. 1, the filling device 1 includes a container conveying section 10 that moves a plurality of containers 2 along a predetermined conveying route R, a powdered or granular material supplying section 20 that supplies powdered or granular material W to the containers 2, and a funnel 30 that receives the powdered or granular material W supplied by the powdered or granular material supplying section 20 and guides it to the containers 2.

[0013] In this embodiment, the powdered or granular material W is crushed titanium sponge and contains titanium sponge pieces and titanium sponge powder. The predetermined transport route R is annular about a central axis O1 extending in the vertical direction. The transport route R is provided with a supply position R1 to which the powdered or granular material W is supplied from the powdered or granular material supply unit 20.

[0014] FIG. 2 is a side view showing the periphery of the container 2 located at the supply position R1. As shown in FIG. 2, the container 2 is a cylindrical body with an open upper end, and for example, a metal drum can can be used. The container 2 has a bottom wall portion 2a and a peripheral wall portion 2b extending upward from the peripheral edge of the bottom wall portion 2a. The peripheral wall portion 2b is formed with two annular ribs 3 that protrude outward and extend in the circumferential direction at positions spaced apart from each other above and below. The container 2 may have a capacity of 100 L or more, and is a size that can accommodate at least 100 kg of powdered or granular material W. The containers 2 are continuously arranged in an annular shape along the conveying route R.

[0015] Returning to Fig. 1, the container conveying section 10 has a plurality of container supporting sections 11 on which a plurality of containers 2 arranged in a circular ring shape around the central axis O1 are placed, and a rotation drive section 12 that rotates the container supporting sections 11 about the central axis O1. The container conveying section 10 moves the containers 2 placed on the container supporting sections 11 along a conveying route R centered on the central axis O1 by rotating the container supporting sections 11 about the central axis O1 using the rotation drive section 12. In this embodiment, the rotation drive section 12 moves the plurality of containers 2 counterclockwise around the central axis O1.

[0016] The powder / granular material supplying unit 20 is a conveying means for conveying the powder / granular material dispensed from a hopper (not shown), and may be, for example, a belt conveyor. The tip of the powder / granular material supplying unit 20 is located directly above a supply position R1 of the conveying route R, and the conveyed powder / granular material W is poured from above through a funnel 30 into the container 2 that has reached the supply position R1 to fill it.

[0017] A plurality of funnels 30 are provided so as to be paired with each of the plurality of containers 2. In this embodiment, the plurality of funnels 30 are provided integrally, but may be provided individually. In FIG. 1, the funnel 30 is shown partially cut out in the circumferential direction by a two-dot chain line. Each of the plurality of funnels 30 rotates around the central axis O1 together with the corresponding container 2. The funnel 30 has an inclined portion 31 that inclines downward toward the inner diameter side, and an opening 32 that extends downward from the lower end of the inclined portion 31 and is located above the corresponding container 2.

[0018] That is, each of the multiple containers 2 is moved around the central axis O1 by the container conveying unit 10 and sequentially reaches the supply position R1. At the supply position R1, the powder or granular material W supplied from the powder or granular material supply unit 20 is received by the inclined portion 31 of the funnel 30 and supplied from the opening 32 to the container 2 located directly below.

[0019] In the filling device 1, the container conveying section 10 conveys the multiple containers 2 at a constant speed around the central axis O1 along the conveying route without stopping, and the powdered or granular material W is supplied from the powdered or granular material supplying section 20 to each container 2 passing the supply position R1. The container conveying section 10 and the powdered or granular material supplying section 20 are set to a speed such that each container 2 is filled with a predetermined amount of powdered or granular material W after moving a predetermined number of revolutions (e.g., several hundred revolutions). This allows the powdered or granular material W in a hopper (not shown) to be evenly filled into the multiple containers 2 from immediately after being dispensed to the end of the dispensed operation. In other words, variation in the properties (e.g., particle size distribution) of the powdered or granular material W among the containers 2 caused by the timing of dispensing from the hopper is suppressed.

[0020] The filling device 1 further includes a striking unit 40 that strikes the container 2 to impart vibration thereto. In this embodiment, a pair of striking units 40 are provided point-symmetrically about the central axis O1, and one of the striking units 40 is disposed at a position to strike the container 2 located at the supply position R1.

[0021] The striking portion 40 has a base end 41 that is fixed outside the movement trajectory S of the container 2 (i.e., it does not displace as the container 2 moves), a tip end 42 that is located inside the movement trajectory S and is supported in a cantilevered state relative to the base end 41, and a connection portion 45 that elastically connects the base end 41 and the tip end 42.

[0022] As shown in Fig. 2, the base end 41 is fixed at its upper end 41a and lower end 41b to a handrail 5 surrounding the periphery of the filling device 1, for example by a fastening means. Fig. 3 is an enlarged side view showing a main part of the hitting part 40, with a partial cross section. Fig. 4 is a plan view of the hitting part 40. Referring to Figs. 3 and 4 together, the base end 41 is a pipe member extending in the vertical direction.

[0023] The tip portion 42 has a cylindrical roller 43 whose axis extends in the vertical direction, and a roller support portion 44 that supports the roller 43 rotatably around this axis. The roller 43 is configured such that its position and size in the height direction spans at least the upper and lower annular ribs 3 of the container 2 in a side view. The outer periphery of the roller 43 is formed from a material that is softer than the container 2, such as rubber or resin. When the connection portion 45 is not elastically deformed, the roller 43 approximately coincides with the axis of the container 2 when viewed from a horizontal direction perpendicular to the direction in which the connection portion 45 extends.

[0024] The connection portion 45 has four connection members 50 arranged in a row above and below, each of which extends in the horizontal direction. With reference to Figures 3 and 4, the uppermost connection member 50 among the connection members 50 will be described as an example. The connection member 50 has a first cylindrical member 52 fixed to the base end portion 41 via a bracket 51 and extending in the horizontal direction, and a second cylindrical member 53 whose tip end is fixed to the roller support portion 44 by welding, for example, and extends in the horizontal direction concentric with the first cylindrical member 52. The second cylindrical member 53 is located entirely closer to the tip end portion 42 than the first cylindrical member 52.

[0025] A first bolt 54 is fastened to the first cylindrical member 52 from above. A second bolt 55 is fastened to the second cylindrical member 53 from above. The first bolt 54 and the second bolt 55 are connected by a wire 56. Specifically, one end 56a of the wire 56 is fastened and fixed in a state in which it is wound around a shaft portion 54b of the first bolt 54 between a head 54a of the first bolt 54 and the first cylindrical member 52. The other end 56b of the wire 56 is fastened and fixed in a state in which it is wound around a shaft portion 55b of the second bolt 55 between a head 55a of the second bolt 55 and the second cylindrical member 53.

[0026] A compression coil spring 57 is provided between the first cylindrical member 52 and the second cylindrical member 53 in an axially compressed state so as to bias the first cylindrical member 52 and the second cylindrical member 53 in a direction separating them from each other in the axial direction. A half of the compression coil spring 57 on the base end 41 side is inserted into the inner periphery of the first cylindrical member 52. A half of the compression coil spring 57 on the tip end 42 side is inserted into the second cylindrical member 53. A base end 57a of the compression coil spring 57 abuts against the shaft portion 54b of the first bolt 54, and a tip end 57b abuts against the head portion 55a of the second bolt 55.

[0027] That is, the compression coil spring 57 is elastically installed between the first cylindrical member 52 and the second cylindrical member 53 which are connected by the wire 56. As a result, coupled with the fact that the second cylindrical member 53 is generally located on the tip end 42 side with respect to the first cylindrical member 52, the tip end 42 is elastically deformable in the vertical and horizontal directions with respect to the base end 41. In addition, the wire 56 prevents the second cylindrical member 53 from sagging with respect to the first cylindrical member 52, and the second cylindrical member 53 maintains a position in which it extends horizontally along the extension direction of the first cylindrical member 52.

[0028] Next, the operation of the striking unit 40 will be described. First, the roller 43 of the striking unit 40 starts from a position downstream of the outer periphery (annular rib 3) of the container 2 on the conveying route. For ease of explanation, in the following explanation, of a pair of containers 2 lined up front and back along the conveying route R, the container 2 passing the supply position R1 is referred to as the preceding container 2L, and the container 2 following it is referred to as the following container 2T.

[0029] As shown in FIG. 1, as the container transport section 10 transports the preceding container 2L in the counterclockwise direction, the rollers 43 come into contact with the outer periphery of the preceding container 2L from the downstream side in the transport direction.

[0030] 5A, as the container conveying unit 10 further conveys the preceding container 2L in the counterclockwise direction, the rollers 43 are pushed by the preceding container 2L and displaced in the counterclockwise direction from the tip of the first cylindrical member 52. At this time, the compression coil spring 57 elastically deforms in the counterclockwise direction from the tip of the first cylindrical member 52.

[0031] Next, as shown in Fig. 5B, as the preceding container 2L is further transported in the counterclockwise direction by the container transport unit 10, the roller 43 is further pushed by the preceding container 2L, and is further displaced in the counterclockwise direction from the tip end of the first cylindrical member 52. The state shown in Fig. 5B shows a state in which the roller 43 abuts the preceding container 2L at a position furthest from the central axis O1, and in this state the roller 43 is displaced the most in the counterclockwise direction.

[0032] At this time, the compression coil spring 57 is in a state in which it is most elastically deformed in the counterclockwise direction from the tip end of the first cylindrical member 52. In this embodiment, the striking section 40 is configured so that when the compression coil spring 57 is in a state in which it is most elastically deformed, a bending angle A, which is the angular difference between the axis of the first cylindrical member 52 and the axis of the second cylindrical member 53, is equal to or greater than 45° and equal to or less than 50°.

[0033] Furthermore, as shown in FIG. 5C, as the preceding container 2L is further conveyed in the counterclockwise direction by the container conveying unit 10, the roller 43 moves away from the outer periphery (annular rib 3) of the preceding container 2L, and the elastic deformation of the compression coil spring 57 is released. As a result, the roller 43 rotates in the clockwise direction due to the elastic restoring force of the compression coil spring 57. At this time, the following container 2T is being conveyed in the counterclockwise direction. That is, the clockwise rotation by the roller 43 and the counterclockwise conveyance of the following container 2T occur simultaneously, and the impact by the striking unit 40 is effectively input to the following container 2T.

[0034] As described above, the axis of the roller 43 coincides with the axis of the container 2 in the side view of Fig. 2, so that the striking force of the roller 43 is input toward the center of the subsequent container 2T. This allows the subsequent container 2T to be struck in a well-balanced manner, and vibrations can be efficiently imparted to the subsequent container 2T. Although not limited thereto, it is preferable that the bending angle A of the compression coil spring 57 becomes zero when the roller 43 strikes the subsequent container 2T.

[0035] The spring constant and bending angle A of the compression coil spring 57 are set so that the impact force of the impact unit 40 is preferably 320N or more and 8000N or less, more preferably 640N or more and 4000N or less. In this embodiment, the impact force of the impact unit 40 is set to 1600N. If the impact force is less than 320N, the above-mentioned effect may not be sufficiently obtained, and if the impact force exceeds 8000N, the subsequent container 2T may be deformed and / or the powder W in the subsequent container 2T may be scattered outside the subsequent container 2T due to the impact, which is not preferable.

[0036] Here, a pair of upper and lower annular ribs 3 are provided on the outer periphery of the container 2, and the striking section 40 (roller 43) is configured to strike both of the pair of upper and lower annular ribs 3 simultaneously. As a result, the impact is easily propagated overall to the succeeding container 2T via the pair of upper and lower annular ribs 3. As shown in Fig. 6A, the filling state of the powdered granular material W before striking is such that the gaps that may be present between the powdered granular material W are reduced after striking, thereby increasing the bulk density of the powdered granular material.

[0037] Moreover, the rollers 43 strike the annular rib 3 of the succeeding container 2T, and do not directly strike any portion other than the annular rib 3. Furthermore, since the rollers 43 are provided rotatably, the rollers 43 are not dragged by the annular rib 3 even when the container 2 is transported in a state of contact with the annular rib 3.

[0038] Thereafter, as shown in Figures 5A to 5C, as the container 2 moves, elastic energy is stored by elastically deforming the compression coil spring 57, and the elastic deformation is released to drive the roller 43 to strike the subsequent container 2T, which is executed sequentially for each subsequent container 2.

[0039] In this embodiment, the multiple containers 2 are struck by the striking unit 40 twice per revolution while being transported along the transport route R, and this is carried out over multiple revolutions until a predetermined amount of powdered or granular material W is filled in the containers 2. As a result, compared to a case where an impact is given to the containers 2 after a predetermined amount of powdered or granular material W is filled (for example, when a predetermined amount of powdered or granular material W is filled at once), an impact is given to the containers 2 each time a small amount of powdered or granular material W is filled, and therefore, voids that may exist between the powdered or granular material W can be reduced while filling, making it easier to increase the bulk density.

[0040] The method for filling powder or granular material W and the device 1 for filling powder or granular material W according to the above embodiment have the following advantages.

[0041] (1) According to the method for filling powder or granular material W according to the above embodiment, While moving the plurality of consecutive containers 2 along a predetermined conveying route R, powdered or granular material W is supplied to a container 2 that has reached a supply position R1 provided on the conveying route R among the plurality of containers 2; The hitting unit 40 has a base end 41 fixed outside the movement path S of the container 2, a tip end 42 positioned inside the movement path S and supported in a cantilever state relative to the base end 41, and a connecting portion 45 that elastically connects between the base end 41 and the tip end 42. The tip portion 42 is brought into contact with the leading container 2L of a pair of containers 2 including a leading container 2L and a trailing container 2T that are consecutive among the multiple containers 2, and is moved in accordance with the movement of the leading container 2L, thereby elastically deforming the connection portion 45, As a result of further movement of the leading container 2L, when the leading end 42 moves away from the leading container 2L, the above-mentioned elastic deformation is released, causing the leading end 42 to strike the following container 2T.

[0042] As a result, the striking section 40 can vibrate the container 2, thereby improving the bulk density of the powdered or granular material W in the container 2. In addition, the movement of the container 2 can be used to store elastic energy in the striking section 40, and the stored elastic energy can be used to drive the striking section 40. Therefore, a separate drive source for driving the striking section 40 is not required, and further, no detection means for detecting the movement of the container 2 is required, so the striking section 40 can be realized with a simple configuration, at low cost, and with low energy consumption.

[0043] Furthermore, since no electric system is required to operate the driving source for driving the striking unit 40 and the detection means, it is possible to prevent the generation of sparks, static electricity, and the like that may be caused by some malfunction of the electric system. As a result, even if the powdered material W contains a material that is easily ignited, such as titanium sponge powder, the risk of the powdered material W igniting due to the electric system can be reduced.

[0044] (2) The powder W is titanium sponge grains, The container 2 may have a weight of 118 kg or more and a volume of 100 L or more when filled with powder or granular material W. As a result, the effects of the invention described above are particularly favorable when the container 2 is large and heavy and it is difficult to vibrate the container manually.

[0045] (3) The container 2 has a bottom wall portion 2a and a peripheral wall portion 2b extending upward from the peripheral edge portion of the bottom wall portion 2a, The peripheral wall portion 2b is provided with two annular ribs 3 which protrude outward and extend in the circumferential direction at positions spaced apart from each other vertically. The strike by the tip 42 may be performed against both of the two annular ribs 3 of the container 2 .

[0046] As a result, by striking the container 2 via the two annular ribs 3 spaced apart vertically on the peripheral wall 2b of the container 2, it is possible to apply vibrations to the container 2 over a wide range (overall) in both the height and circumferential directions. Moreover, because the highly rigid annular rib 3 of the container 2 is struck, deformation of the container 2 due to the strike is prevented. Furthermore, when information such as product identification information such as the company name and product name, and process control information such as the lot number is printed in a location on the peripheral wall 2b of the container 2 other than the two annular ribs 3 (for example, between the two annular ribs 3), the printed information is prevented from being erased by the strike.

[0047] (4) The tip 42 may be formed of a roller 43, and when the roller 43 is pressed against the outer circumferential surface of the container 2, it may be caused to roll along the outer circumferential surface of the moving container 2.

[0048] As a result, tip 42 rolls along the outer peripheral surface of container 2 and is therefore less likely to be dragged by the outer peripheral surface of container 2. This prevents tip 42 from being dragged by the outer peripheral surface of container 2, leaving a trace of tip 42 on container 2, thereby preventing container 2 from becoming soiled.

[0049] The powder / granular material filling method and powder / granular material filling device according to the present invention are not limited to the configurations of the above-described embodiments, and various modifications are possible.

[0050] In the above embodiment, the striking portion 40 is configured so that the tip portion 42 is located on the movement trajectory S of the container 2, but instead, the striking portion 40 may be configured so that it can be selectively fixed to either an operating position where the tip portion 42 is located on the movement trajectory S of the container, or a retracted position where the tip portion 42 is located outside the movement trajectory S of the container 2. When the striking portion 40 is fixed to the operating position, the striking portion 40 can impart vibrations to the container 2, and when the striking portion 40 is moved to the retracted position, the striking portion 40 can stop striking the container 2.

[0051] In the above embodiment, the connection portion of the striking portion 40 is configured with four connecting members 50, but this is not limited to the above. That is, the connecting member 50 may be configured with one, two, three, five or more.

[0052] In the above embodiment, the hitting portion 40 is provided at two locations point-symmetrically with respect to the central axis O1, but this is not limited thereto. That is, the hitting portion 40 may be provided at only one location, or at three or more locations. When multiple hitting portions 40 are provided, they may be arranged at equal intervals or at unequal intervals.

[0053] In the above embodiment, the compression coil spring 57 is used as the elastic member in the connection portion 45, but any appropriate elastic member capable of being displaced in the horizontal direction, such as a leaf spring, can be used.

[0054] In the above embodiment, the case where a plurality of containers 2 are transported along a circular transport route R has been described as an example, but the present invention is not limited thereto. For example, the transport route R may be configured in a polygonal shape. Furthermore, the present invention may also be applied to a case where the transport route R is configured in a linear shape rather than a circular shape, in which case the containers 2 are subjected to vibrations equal to the number of striking sections 40.
