[First Embodiment]
1 and 2 show a dust throwing device of the present invention.

  The dust throwing-in apparatus 1 is for throwing dust into the storage tank 6 through a charging hopper 61 as a charging part provided in the upper part of the storage tank 6.

  As the storage tank 6, for example, a drum is provided so as to be rotatable around a horizontal axis as shown in the figure, and the dust thrown into the feeding hopper 61 by the dust throwing device 1 is introduced into the drum through a chute (not shown), By rotating the drum, the blade provided inside transports the drum to the discharge port side opposite to the charging hopper 61 and stores it while compressing it. The stored dust is appropriately discharged from the discharge port.

  Hereinafter, the dust throwing-in apparatus 1 is demonstrated, referring FIG.1 and FIG.2.

  The dust throwing device 1 includes two buckets 2 and 2 provided side by side in a transfer path 3 standing on the side of the charging hopper 61 of the storage tank 6.

  Each bucket 2 is provided so as to be able to move up and down between a lower storage position where dust is stored in the bucket 2 by a driving means 4 which will be described later and an upper input position where dust is input into the storage tank 6 through the input hopper 61. It has been.

  Moreover, as shown in FIG. 2, the bottom part of the bucket 2 is formed in the inverted triangle shape, and is made | formed at the discharge port 21 by which the inclined surface by the side of the storage tank 6 was opened. The discharge port 21 is openable and closable by a side-view fan-shaped open / close lid 22 rotatably provided at the lower portion of the bucket 2, and is opened and closed by an open / close guide 23 erected on the outer side of each side. It is configured.

  Specifically, taking the left bucket 2 in FIG. 1 as an example, a guide pin 24 protrudes outwardly on the outer surface of the opening / closing lid 22, and this guide pin 24 is located inside the opening / closing guide 23. It is slidably inserted in. As shown in FIG. 2, the open / close guide 23 is formed in a straight line from the storage position to the charging position facing the charging hopper 61, and the upper end portion facing the charging hopper 61 is refracted toward the charging hopper 61.

  While the bucket 2 is moving up and down between the storage position and the front position, the guide pin 24 slides on the linear portion of the open / close guide 23 so that the open / close lid 22 closes the discharge port 21. At the closing position, the guide pin 24 is disposed at the refracted portion of the open / close guide 23 and the height positional relationship between the center of rotation of the open / close lid 22 and the guide pin 24 is reversed, so that the open / close lid 22 is moved outward. And the discharge port 21 is opened.

  In addition, the opening / closing guide 23 and the guide pin 24 are also provided symmetrically with the opening / closing guide 23 and the guide pin 24 provided in the left bucket 2 described above with respect to the right bucket 2 in FIG.

  Moreover, the front side surface on the opposite side to the discharge port 21 of each bucket 2 is made into the input port 25 (refer FIG. 2) opened. The input port 25 is an opening for accepting the input of dust from the input means 5 to be described later when the bucket 2 is disposed at the storage position. When the bucket 2 is moved up and down toward the input position, the dust leaks from the input port 25. The front wall of the conveyance path 3 is closed so as not to come out.

  The buckets 2 and 2 are arranged alternately at the storage position and the loading position by the driving means 4.

  Specifically, as shown in FIG. 1, the drive means 4 includes sprockets 41 and 42 disposed vertically between the left and right buckets 2 and 2, a drive chain 43 wound around the sprockets 41 and 42, and a drive A motor 44 is provided.

  Each of the sprockets 41 and 42 is integrally provided on a horizontal shaft that is horizontally supported by the apparatus main body.

  As shown in FIG. 2, the drive motor 44 has a sprocket 45a provided integrally with its output shaft, a sprocket 45b provided on the front end side of the horizontal shaft 41a on the sprocket 41 side, and wound around these sprockets 45a and 45b. It is connected to the horizontal shaft 41a through a transmission mechanism comprising a rotated chain 45c. Accordingly, the drive chain 43 is moved up and down in the forward and reverse directions via the sprockets 41 and 42 by rotating the horizontal shaft 41 a in the same forward and reverse directions by rotationally driving the drive motor 44 in the forward and reverse directions. .

  The buckets 2 and 2 are connected to the drive chain 43 that moves in the forward and reverse directions in this way via the connecting member 43a. Each of the buckets 2 and 2 is connected to the drive chain 43 so that when the one bucket 2 is disposed at the receiving position, the other bucket 2 is disposed at the closing position. The buckets 2 and 2 are alternately arranged at the storage position and the loading position by moving the bucket up and down.

  The positioning of the buckets 2 and 2 at the storage position and the loading position may be performed by detecting with a detection device such as a limit switch, a proximity sensor or a photoelectric sensor, and the number of rotations of the drive motor 44 is detected. The detection may be performed by a device.

  On the other hand, throwing means 5 is provided in front of each bucket 2, 2 arranged at the storage position. As shown in FIG. 2, the charging means 5 is provided in a pair corresponding to each bucket 2, 2 on a loading plate A disposed in front of each bucket 2. Each loading means 5 is provided with a loading port 51 formed in the loading plate A so as to be freely opened and closed by an opening / closing lid 52, and a chute 53 is provided at the loading port 51 so as to face the loading portion 25 of the bucket 2. By opening 52, dust is accommodated in the bucket 2 through the inlet 51, chute 53, and inlet 25.

  Next, the operation of throwing dust into the storage tank 6 by the dust throwing device 1 configured as described above will be described.

  First, the opening / closing lid 52 on the bucket 2 side disposed at the accommodation position is opened, dust is introduced into the insertion port 51, and the dust is accommodated in the bucket 2 through the chute 53.

  When the dust is accommodated in the bucket 2 in this way, the drive motor 44 is rotationally driven to move the drive chain 43 so as to raise the bucket 2 arranged on the accommodation position side, thereby bringing the bucket 2 into the loading position. Raise towards. At this time, the bucket 2 slides while the guide pin 24 is guided by the opening / closing guide 23 without changing the height positional relationship between the guide pin 24 and the rotation center of the opening / closing lid 22, so that the discharge port 21 is moved. In the state closed by the opening / closing lid 22, it ascends just before the closing position.

  When the bucket 2 is raised to the position before the loading position, the height positional relationship between the guide pin 24 and the rotation center of the opening / closing lid 22 is higher than the guide pin 24 at the rotation center of the opening / closing lid 22. The guide pin 24 is arranged at the bent upper end portion of the opening / closing guide 23 while changing so that the opening / closing lid 22 rotates outward to open the discharge port 21. As a result, the dust in the bucket 2 is introduced into the storage tank 6 through the introduction hopper 61 from the discharge port 21.

  When one of the buckets 2 arranged at the accommodation position is arranged at the loading position in this way, the other bucket 2 arranged at the loading position is arranged at the accommodation position. At this time, the opening / closing lid 22 of the other bucket 2 is rotated by an operation reverse to the above-described operation to close the discharge port 21 and is disposed at the accommodation position in this state.

  Then, in the same manner as described above, the other bucket 2 disposed at this storage position is charged with dust by the loading means 5 and stored. When dust is stored in the other bucket 2, the other bucket 2 is raised to the charging position in the same manner as described above, and dust is charged into the storage tank 6 from the discharge port 21. The bucket 2 is again lowered to the accommodation position, and dust can be put into the one bucket 2.

  In this way, the left and right buckets 2 are alternately and repeatedly transferred to the storage position and the charging position, whereby the dust can be sequentially charged into the storage tank 6 (see FIGS. 3 and 4).

  In addition, what is necessary is just to perform the raising / lowering operation | movement of the bucket 2 on either side in connection with the opening / closing operation | movement of every opening / closing lid | cover 52. FIG. Further, the bucket 2 may be moved up and down when the opening / closing lid 52 is opened and closed a predetermined number of times. In other words, since the total input amount can be estimated from the amount of dust that can be input by opening the opening / closing lid 52 once, the opening / closing number of the opening / closing lid 52 is set by comparing this with the storage volume of the bucket 2. 2 may be raised and lowered. In this case, the opening / closing lid 52 may be detected by a detection device 54 (see FIG. 2) such as a limit switch or a proximity sensor, and the right and left buckets 2 may be moved up and down based on the detection result. Furthermore, you may make it perform the raising / lowering operation | movement of each bucket 2 by switch operation.

  Further, when the bucket 2 is not disposed at the storage position, it is necessary to secure the open / close lid 52 on the bucket 2 side in a closed state to prevent the dust from being thrown in by opening. Similarly, while the left and right buckets 2 are moving up and down, both the open / close lids 52 must be secured in a closed state to prevent dust from being thrown in by opening.

  In this way, the right and left buckets 2 that accommodate the dust can be integrated into the apparatus so that the bucket 2 can be prevented from being accidentally dropped, and thus damage to the members and personal injury can be reliably prevented. It can be ensured, and dust can be prevented from scattering to the surroundings, thereby preventing deterioration of the surrounding environment.

  Further, since the left and right buckets 2 can be moved up and down by a simple mechanism using a single driving means 4, the entire apparatus can be reduced in size even when the buckets 2 are provided on the left and right sides, and the installation space can be saved. Can also be achieved.

  Further, since the left and right buckets 2 are alternately transferred, the dust cannot be accommodated in the bucket until it reciprocates between the accommodation position and the loading position as in the case of raising and lowering one bucket. When the bucket 2 reaches the storage position from the charging position, it becomes possible to store the dust in the bucket 2, thereby reducing the time during which the dust cannot be input at the storage position to half that of raising and lowering one bucket. The thrower can throw the dust efficiently at the storage position.

  In addition, since the dust is accommodated in the bucket 2 disposed at the lower accommodation position, the thrower's dust throwing position through the throwing means 5 can be made as low as possible, thereby facilitating the throwing of the dust. Barrier-free can also be supported.

[Second Embodiment]
5 and 6 show another example of the dust throwing device of the present invention. In addition, the same code | symbol is attached | subjected to the member similar to the member demonstrated in 1st Embodiment mentioned above, and description is abbreviate | omitted.

  This dust throwing device 1 includes buckets 2, 2 provided on the left and right sides in a transfer path 3 erected facing the charging hopper 61 side of the storage tank 6 as described above.

  Each bucket 2 is formed in an upper surface opening 2a having an upper surface opened, and is lifted and lowered along a guide rail 7 (see FIG. 6) erected outward from each side of the bucket 2 by the driving means 4. By doing so, it is arranged at the lower storage position (see the solid line in FIG. 6) for storing the dust in the bucket 2 and the reverse position (see the two-dot chain line in FIG. 6) which is the upper input position.

  Specifically, taking the lower bucket 2 in FIG. 5 as an example, the base end of the guide arm 26 is fixed to the outer surface of the bucket 2 as shown in FIG. A guide roller 27 is provided at the tip. The guide roller 27 is slidably inserted into a guide rail 7 that is erected outside the bucket 2.

  The guide rail 7 is formed in a straight line from the accommodation position to a position before the reversal position facing the charging hopper 61, and the upper end portion facing the charging hopper 61 is refracted toward the charging hopper 61.

  While the bucket 2 is moving up and down between the storage position and the reverse position, the guide roller 27 slides on the linear portion of the guide rail 7 so that the bucket 2 is held in a horizontal state. 27 is disposed in the refracted portion of the guide rail 7 so that the height positional relationship between the base end portion of the guide arm 26 and the guide roller 27 is reversed, so that the bucket 2 is reversed.

  Note that the guide arm 26, the guide rail 7, and the like are provided symmetrically with the guide arm 26, the guide rail 7, and the like provided in the left bucket 2 described above with respect to the upper bucket 2 in FIG.

  Although not specifically shown here, the drive means 4 is sprockets arranged up and down between the left and right buckets 2 and 2 and wound around these sprockets, like the drive means 4 of the first embodiment described above. A drive chain and a drive motor are provided, and each bucket 2, 2 is connected to the drive chain so that when one bucket 2 is placed in the storage position, the other bucket 2 is placed in the reverse position. .

  Next, the operation of throwing dust into the storage tank 6 by the dust throwing device 1 configured as described above will be described.

  First, the opening / closing lid 52 on the bucket 2 side disposed at the accommodation position is opened, dust is introduced into the insertion port 51, and the dust is accommodated in the bucket 2 through the chute 53.

  When the dust is accommodated in the bucket 2 in this way, the bucket 2 disposed on the accommodation position side is raised by the driving means 4, and thereby the bucket 2 is transferred to the reverse position. At this time, the bucket 2 maintains a horizontal state by sliding while the guide roller 27 is guided by the guide rail 7 without changing the height positional relationship between the guide roller 27 and the base end portion of the guide arm 26. In this state, it rises to the front of the reverse position.

  When the bucket 2 rises to the position before the reversal position, the height positional relationship between the guide roller 27 and the base end portion of the guide arm 26 is higher than the guide roller 27 at the base end portion of the guide arm 26. By changing in this way, the bucket 2 starts to reverse, and the guide roller 27 is arranged at the upper end of the refracted guide rail 7 so that the upper surface opening 2a of the bucket 2 is inverted so as to be on the lower side. As a result, the dust in the bucket 2 is charged into the storage tank 6 through the charging hopper 61 from the upper surface opening 2a.

  When one bucket 2 arranged in the accommodation position in this way is arranged in the reverse position, the other bucket 2 arranged in the reverse position is arranged in the accommodation position. At this time, the other bucket 2 is arranged from the reverse position to the accommodation position by an operation reverse to the operation described above.

  Then, in the same manner as described above, the other bucket 2 disposed at this storage position is charged with dust by the loading means 5 and stored. When dust is stored in the other bucket 2, the other bucket 2 is raised to the reversal position in the same manner as described above, the dust is put into the storage tank 6, and one bucket 2 arranged at the reversal position is The container is lowered again to the storage position, and dust can be put into the one bucket 2.

  In this way, the left and right buckets 2 are alternately and repeatedly transferred to the storage position and the charging position, whereby the dust can be sequentially charged into the storage tank 6.

  Note that the timing for raising and lowering the left and right buckets 2 and the prevention of throwing in dust when the bucket 2 is not disposed at the storage position may be the same as in the first embodiment.

  By configuring the dust throwing apparatus 1 in this way, the same effects as the dust throwing apparatus of the first embodiment described above can be obtained.

  That is, by integrating the right and left buckets 2 into the apparatus, it is possible to prevent the bucket 2 from being accidentally dropped, thereby reliably preventing damage to members and personal injury, and ensuring high safety. At the same time, dust can be prevented from scattering to the surroundings, and the surrounding environment can be prevented from deteriorating.

  Further, since the left and right buckets 2 can be moved up and down by a simple mechanism using a single driving means 4, the entire apparatus can be reduced in size even when the buckets 2 are provided on the left and right sides, and the installation space can be saved. Can also be achieved.

  Furthermore, since the left and right buckets 2 are alternately transferred, the dust cannot be accommodated in the bucket until it reciprocates between the accommodation position and the reversal position as in the case of raising and lowering one bucket. When the bucket 2 reaches the storage position from the reverse position, it becomes possible to store the dust in the bucket 2, thereby reducing the time during which the dust cannot be thrown in the storage position to half that of raising and lowering one bucket. The thrower can throw the dust efficiently at the storage position.

  In addition, since the dust is accommodated in the bucket 2 disposed at the lower accommodation position, the thrower's dust throwing position through the throwing means 5 can be made as low as possible, thereby facilitating the throwing of the dust. Barrier-free can also be supported.

  Note that the above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope thereof.

  For example, the storage tank 6 into which the dust is thrown in by the dust throwing device 1 is not limited to a rotatable drum, but may be anything as long as the dust thrown in from the upper charging portion by the dust throwing device 1 is stored inside.

It is a front view which shows the dust throwing-in apparatus of this invention. It is a side view which similarly shows a dust throwing-in apparatus. It is a perspective view for demonstrating raising / lowering operation | movement of a bucket on either side.
