JP 2011-183806 A

  When a processing object including a plurality of materials is struck in this way, dissociation between the materials is promoted by the impact force. Therefore, in the beating device, it is important to efficiently give the hitting force by the hitting member to the object to be processed, that is, to improve the hitting efficiency.

  However, in the beating device described in Patent Document 1, the object to be processed is moved away from the tapping member by the wind pressure when the tapping member rotates. This is a factor that weakens the striking force of the striking member and lowers the striking efficiency.

  The present invention has been made in view of the above problems, and an object thereof is to provide a beating device having a structure suitable for increasing the hitting efficiency.

  The beating apparatus according to the present invention dissociates the second material from the first material by beating a processing object including the first material and the second material attached to the first material. A beating device that rotates around a central axis of the beating device, and a tapping member that is attached around the rotating shaft and beats the object to be processed while rotating together with the rotating shaft. An opening is formed in the hitting surface of the hitting member.

  In this beating device, an opening is formed in the hitting surface of the hitting member. When the hitting member rotates, air escapes through the opening, so that the wind pressure received by the object to be processed can be kept small. Thereby, compared with the case where the opening part is not formed, strong striking force can be given with respect to a process target object.

  According to the present invention, a beating device having a structure suitable for increasing the beating efficiency is realized.

(First embodiment)

  1 and 2 are end views showing a first embodiment of a beating device according to the present invention. The beating device 1 promotes dissociation of the second material from the first material by beating a processing object including the first material and the second material attached to the first material. is there.

  The object to be treated is, for example, a sanitary product as a defective product. As sanitary goods, a paper diaper, a sanitary napkin, a urine picking pad, etc. are mentioned, for example. In the present embodiment, a case where the object to be treated is a paper diaper, the first material is plastic, and the second material is a water-absorbing polymer (including a highly water-absorbing polymer) will be described as an example. In addition, it is preferable that the process target object is shredded into an appropriate size in advance. For such shredding, for example, a crusher or a pulverizer can be used.

  The beating device 1 includes a rotating shaft 10 and a beating member 20. The rotating shaft 10 has a substantially cylindrical shape and is provided so as to be rotatable around its central axis. The central axis of the rotating shaft 10 is horizontal. End faces parallel and perpendicular to the central axis are shown in FIGS. 1 and 2, respectively. The outer diameter of the rotating shaft 10 is, for example, not less than 10 cm and not more than 20 cm.

  A tapping member 20 is attached around the rotary shaft 10. In the present embodiment, a plurality of tapping members 20 are provided. As can be seen from FIG. 1, the tapping member 20 is provided at a plurality of locations (5 locations in the present embodiment) along the central axis of the rotating shaft 10. As can be seen from FIG. 2, a plurality (eight in this embodiment) of tapping members 20 are radially attached around the rotary shaft 10 at each location. Each tapping member 20 is arranged so that the thickness direction thereof is orthogonal to the central axis.

  These tapping members 20 strike a paper diaper while rotating together with the rotary shaft 10. Specifically, the tapping member 20 has a plate shape and strikes a paper diaper with the plate surface as a tapping surface. Here, the striking surface refers to a surface that strikes a paper diaper, that is, a surface that comes into contact with the paper diaper when tapped. The plate surface is a surface perpendicular to the thickness direction of the tapping member 20. As a material of the hitting member 20, for example, a metal can be used.

  When the maximum rotation radius R1 (see FIG. 2) of the tapping member 20 is 1, the maximum length L1 of the tapping member 20 is preferably 0.5 or more. Here, the maximum turning radius R1 is defined as the distance from the central axis of the rotating shaft 10 to the tip of the tapping member 20 (if the distance varies depending on the tapping member 20, the maximum one of them). The value of the maximum turning radius R1 is, for example, not less than 13 cm and not more than 25 cm. Further, the maximum length L1 is defined as the length of the tapping member 20 (if the length varies depending on the tapping member 20, the maximum one of them). The value of the maximum length L1 is, for example, not less than 8 cm and not more than 15 cm.

  As shown in FIG. 1, a plurality of openings 22 are formed in the hitting surface of the hitting member 20. The plurality of openings 22 are two-dimensionally arranged on the hitting surface of the hitting member 20. Specifically, for each tapping member 20, a total of twelve openings 22 are arranged in two in the width direction (the central axis direction of the rotating shaft 10) and six in the length direction (the radial direction of the rotating shaft 10). ing. Each opening 22 has a shape and a size such that a paper diaper piece as a processing object does not pass through. In the present embodiment, the shape of each opening 22 is circular in plan view. The diameter of each opening 22 is, for example, 2 mm or more and 10 mm or less. These openings 22 are provided so that air escapes through the openings 22 when the tapping member 20 rotates.

  A cylindrical housing portion 30 is provided so as to surround the rotating shaft 10 and the tapping member 20. The accommodating portion 30 has a substantially cylindrical shape and can rotate around its central axis. The central axis of the housing part 30 coincides with the central axis of the rotary shaft 10. That is, the rotating shaft 10 and the accommodating part 30 have the same central axis. However, the accommodating part 30 rotates independently of the rotating shaft 10. In this embodiment, the rotating shaft 10 and the accommodating part 30 rotate in the opposite directions around the central axis. The container 30 accommodates a paper diaper that is a processing object. The internal diameter of the accommodating part 30 is 30 cm or more and 50 cm or less, for example. Moreover, the space | interval of the internal peripheral surface of the accommodating part 30 and the front-end | tip of the tapping member 20 is 5 mm or more and 30 mm or less, for example.

  As shown in FIG. 2, a protrusion 32 is provided on the inner peripheral surface of the accommodating portion 30. The ridge 32 extends in the central axis direction of the housing portion 30 (direction perpendicular to the paper surface of FIG. 2). The protrusion 32 extends over substantially the entire center axis direction of the housing portion 30. Further, the protrusion 32 has a substantially triangular cross section. The height of the protrusion 32 (the length in the radial direction of the accommodating portion 30) is, for example, 3 mm or more and 20 mm or less. It is preferable that p protrusions 32 are provided (p: an integer of 3 to 5). The p protrusions 32 are arranged on the inner peripheral surface of the accommodating portion 30 at equal intervals. That is, on the end face (end face shown in FIG. 2) perpendicular to the central axis of the housing portion 30, a line segment connecting one protrusion 32 and the central axis and the adjacent protrusion 32 and the central axis are connected. The angle α formed with the line segment is substantially equal to 360 ° / p. In this embodiment, p = 4 and α = 90 °.

  In the beating apparatus 1, when the rotating shaft 10 is rotated in a state where the paper diaper is housed in the housing portion 30, the tapping member 20 that rotates together with the rotating shaft 10 repeatedly strikes the paper diaper. Then, dissociation of the water-absorbing polymer from the plastic is promoted by the impact force or the like. At this time, a part of the water-absorbing polymer is completely dissociated from the plastic. The water-absorbing polymer thus separated from the paper diaper is discharged out of the beating apparatus 1 by a discharge means (not shown). In addition, even for a water-absorbing polymer that has not been dissociated from the plastic, the adhesive force to the plastic is reduced due to the striking force of the tapping and the like, and the polymer easily becomes dissociated. The paper diaper after being beaten in the beating device 1 is transferred to a separating device such as a rotary sieve as necessary, where the remaining water-absorbing polymer is separated. In addition, when a process target object is a paper diaper like this embodiment, a fluff pulp is also isolate | separated with a water absorbing polymer.

  The effect of the beating device 1 will be described. In the beating device 1, an opening 22 is formed in the hitting surface of the hitting member 20. When the tapping member 20 rotates, air escapes through the opening 22, so that the wind pressure received by the paper diaper can be kept small. Thereby, compared with the case where the opening part 22 is not formed, strong striking force can be given with respect to a paper diaper. Therefore, the beating device 1 having a structure suitable for increasing the beating efficiency is realized. In addition, air escape through the opening 22 reduces air resistance when the tapping member 20 rotates. This contributes to a reduction in power consumption of the beating device 1.

  A plurality of openings 22 are formed on the tapping surface of the tapping member 20. By increasing the number of openings 22 in this way, a large opening area can be ensured as the entire tapping member 20. Thereby, since more air can be escaped, the wind pressure which a paper diaper receives can be suppressed further smaller.

  In this regard, as a means for securing a large opening area as the entire tapping member 20, it is conceivable to design one opening 22 large. However, the size of the opening 22 has a problem that the degree of freedom in design is low because there is a restriction that the paper diaper piece that is the object to be processed must not pass. According to the means for increasing the number of openings 22 as in the present embodiment, a large opening area can be secured as a whole of the tapping member 20 without changing the size of each opening 22, thereby avoiding such a problem. can do.

  Around the rotating shaft 10, a plurality of tapping members 20 that are radially attached are provided. Thereby, since the paper diaper is struck by the plurality of tapping members 20 while the rotating shaft 10 makes one rotation, the tapping of the paper diaper with the tapping member 20 can be performed more efficiently.

  The tapping member 20 has a plate shape, and is configured to strike a paper diaper with the plate surface as a tapping surface. By striking the plate surface of the striking member 20 in this way, a strong striking force can be applied to the paper diaper. In addition, this configuration also provides an advantage that the paper diaper that is the object to be processed is less likely to get tangled with the tapping member 20.

  By making the hitting member 20 longer, the hitting surface becomes wider, so that more disposable diapers can be hit while the rotary shaft 10 makes one rotation. From this viewpoint, when the maximum rotation radius R1 of the tapping member 20 is 1, the maximum length L1 of the tapping member 20 is preferably 0.5 or more.

  In this regard, in the conventional beating device, there is a problem that when the hitting member is lengthened, the wind pressure and the air resistance when the hitting member rotates are remarkably increased. According to the present embodiment, since air escapes through the opening 22 as described above, even if the tapping member 20 is lengthened, an increase in wind pressure and air resistance when the tapping member 20 rotates can be suppressed to a low level.

  An accommodating portion 30 is provided so as to surround the rotating shaft 10 and the tapping member 20. For this reason, a part of the paper diaper struck by the striking member 20 is rubbed against the inner peripheral surface of the accommodating portion 30. Thereby, in addition to the striking force acting on the paper diaper when struck by the tapping member 20, the frictional force acting on the paper diaper when being rubbed against the inner peripheral surface of the housing portion 30 also contributes to the dissociation of the water-absorbing polymer from the plastic. To do. In addition, a part of the paper diaper is hit by the hitting member 20 and collides with the inner peripheral surface of the housing portion 30 and the like. At this time, the impact force acting on the paper diaper also contributes to the dissociation of the water-absorbing polymer from the plastic.

  The rotating shaft 10 and the accommodating portion 30 are configured to rotate in the opposite directions around the same central axis. Thereby, since the force which a paper diaper receives from the internal peripheral surface of the accommodating part 30 increases, dissociation of the water absorbing polymer from a plastic is further promoted.

  The housing part 30 is provided with a protrusion 32. When the ridge 32 is not provided, the disposable diaper tends to gather at the lower part of the storage unit 30 due to the influence of gravity. On the other hand, in the case of this embodiment, the paper diaper in the storage unit 30 is easily lifted by the ridges 32, and thus easily reaches the upper part of the storage unit 30. Such a scooping action allows the disposable diaper to spread over a wide area on the inner peripheral surface of the accommodating portion 30. Thereby, more paper diapers can be beaten by the tapping member 20 while the rotary shaft 10 makes one rotation.

Moreover, dissociation of the water-absorbing polymer from the plastic is promoted by an impact when the paper diaper falls from the upper part of the housing part 30. Further, since the protrusion 32 is provided, the paper diaper hit by the hitting member 20 may be rubbed against the inner peripheral surface of the housing portion 30 in a state of being caught by the protrusion 32. In this case, since the force is difficult to escape, the frictional force applied to the paper diaper increases, thereby further promoting the dissociation of the water-absorbing polymer from the plastic.
(Second Embodiment)

  3 and 4 are end views showing a second embodiment of a beating device according to the present invention. The beating device 2 promotes dissociation of the second material from the first material by beating a processing object including the first material and the second material attached to the first material. is there. Also in this embodiment, a case where the object to be processed is a paper diaper, the first material is plastic, and the second material is a water-absorbing polymer will be described as an example. The beating device 2 includes a rotating shaft 10, a beating member 20, and a housing portion 40. The configurations of the rotating shaft 10 and the hitting member 20 are as described in the first embodiment.

  A cylindrical housing portion 40 is provided so as to surround the rotating shaft 10 and the tapping member 20. The accommodating portion 40 has a substantially cylindrical shape and can rotate around its central axis. The central axis of the accommodating portion 40 coincides with the central axis of the rotation shaft 10. That is, the rotating shaft 10 and the accommodating part 40 have the same central axis. However, the accommodating part 40 rotates independently of the rotating shaft 10. In the present embodiment, the rotating shaft 10 and the accommodating portion 40 rotate in opposite directions around the central axis. The container 40 accommodates a paper diaper that is a processing object. The internal diameter of the accommodating part 40 is 30 cm or more and 50 cm or less, for example. Moreover, the space | interval of the internal peripheral surface of the accommodating part 40 and the front-end | tip of the tapping member 20 is 5 mm or more and 30 mm or less, for example. As shown in FIG. 4, a protrusion 32 is provided on the inner peripheral surface of the accommodating portion 40. The configuration of the ridge 32 is as described in the first embodiment.

  FIG. 5 is a side view showing the accommodating portion 40. A large number of holes 42 are formed in the accommodating portion 40. The hole 42 is formed over substantially the entire housing portion 40. The hole 42 does not allow the plastic contained in the paper diaper to be processed to pass through, but allows the water-absorbing polymer to pass therethrough. The diameter of the hole 42 is, for example, 5 mm or more and 10 mm or less. Note that FIG. 4 described above shows an end surface that does not include the hole 42.

  The effect of the beating device 2 will be described. In the beating device 2, an accommodating portion 40 having a large number of holes 42 is provided. Thereby, the water-absorbing polymer separated from the paper diaper in the accommodating part 40 can be easily discharged out of the beating apparatus 2 through the hole 42. Other effects of the beating device 2 are the same as those of the beating device 1.

  The present invention is not limited to the above embodiment, and various modifications can be made. In the said embodiment, sanitary goods, such as a paper diaper, were illustrated as a process target object. However, the processing object is not particularly limited as long as it includes a plurality of materials attached to each other. Examples of processing objects other than sanitary goods include PVC wallpaper as waste. When the object to be treated is PVC wallpaper, the first material is paper and the second material is polyvinyl chloride.

  In the said embodiment, the circular opening part 22 was illustrated by planar view. However, the shape of the opening 22 is arbitrary, and may be rectangular in plan view, for example. Alternatively, the opening 22 may have a slit shape as shown in FIG. In the figure, a slit-like opening 22 extending in the length direction of the tapping member 20 is provided. Moreover, you may form the opening part 22 by making the substantially whole or a part of the hit | damage member 20 into net shape. In that case, the mesh of the tapping member 20 corresponds to the opening 22. FIG. 7 shows an example in which substantially the entire hitting member 20 is made net-like.

  In the said embodiment, the case where all the some opening parts 22 had the same opening area was illustrated. However, at least two of the plurality of openings 22 may have different opening areas. For example, as shown in FIG. 8, the plurality of openings 22 include an opening 22a (first opening) and an opening 22b (second opening) having an opening area smaller than the opening 22a. May be included. The opening 22a is formed closer to the tip of the tapping member 20 than the opening 22b. With such a configuration, more air can be released at a position where a relatively large wind pressure is generated (a position relatively close to the tip of the tapping member 20). As shown in FIG. 9, the plurality of openings 22 may be formed such that the opening area gradually increases as approaching the tip of the tapping member 20.

  In the said embodiment, the example in which the some opening part was provided in each hitting member was shown. However, only one opening may be provided for each tapping member.

  In the above embodiment, as shown in FIG. 10, the concavo-convex portion 24 may be formed on the striking surface of the striking member 20. In the figure, the rotating shaft 10 and the tapping member 20 rotate counterclockwise (counterclockwise) as indicated by arrows. The concavo-convex portion 24 is formed on substantially the whole or a part of the region where the opening 22 is not formed on the striking surface of the striking member 20. By hitting with such an uneven surface, it is possible to give a stronger impact to the object to be processed than when hitting with a flat surface.

  In the said embodiment, the case where all the some tapping members 20 had the same length was illustrated. However, at least two of the plurality of tapping members 20 may have different lengths. For example, as shown in FIG. 11, the plurality of hitting members 20 may include a hitting member 202 (first hitting member) and a hitting member 204 (second hitting member) shorter than the hitting member 202. Good. In this example, the tapping members 202 and the tapping members 204 are alternately arranged around the rotating shaft 10 at each location along the central axis of the rotating shaft 10. In this case, the maximum rotation radius R1 of the tapping member 20 is equal to the distance from the central axis of the rotating shaft 10 to the tip of the tapping member 202 as defined above. Further, the maximum length L1 of the tapping member 20 is equal to the length of the tapping member 202.

  The advantages of this configuration will be described with reference to FIGS. When all of the plurality of tapping members 20 have the same length, the processing object tends to be unevenly distributed in a narrow region S1 in the vicinity of the inner peripheral surface of the housing portion 30 due to the wind pressure of the tapping member 20 as shown in FIG. become. On the other hand, when the plurality of hitting members 20 have different lengths, as shown in FIG. 13, the processing object is likely to enter the radial inside of the rotating shaft 10, and thus is dispersed in a wider region S <b> 2. It becomes like this. Therefore, the hitting with the hitting member 20 can be performed more efficiently. That is, more processing objects can be beaten while the rotating shaft 10 makes one rotation.

  Further, in this case, the processing object can be beaten with the tip of the hitting member 20 at a plurality of positions in the radial direction of the rotating shaft 10. That is, the object to be treated can be beaten at the distal end portion of the hitting member 202 at the relatively outer side in the radial direction and at the distal end portion of the hitting member 204 at the relatively inner side in the radial direction. In this way, when hitting at the tip of the hitting member 20, the object to be processed collides with the corner of the tip. Therefore, hitting with the tip of the hitting member 20 is advantageous in giving a strong impact to the object to be processed.

  The plurality of tapping members 20 may include three types of tapping members having different lengths. For example, as shown in FIG. 14, the plurality of tapping members 20 may include a tapping member 206 (third tapping member) that is shorter than the tapping member 204 in addition to the tapping members 202 and 204 described above. . In this example, the tapping member 202, the tapping member 204, and the tapping member 206 are arranged in this order from the front to the rear in the rotation direction of the rotary shaft 10 at each location along the central axis of the rotary shaft 10. . In the figure, the rotating shaft 10 rotates counterclockwise (counterclockwise).

  In the said embodiment, the plate-shaped tapping member was illustrated. However, the hitting member may be rod-shaped as shown in FIGS. 15 and 16. As shown in FIG. 15, an opening 52 is formed on the striking surface of the rod-shaped striking member 50. As shown in FIG. 16, the opening 52 is formed so as to penetrate the tapping member 50 along the rotation direction of the rotary shaft 10. The opening 52 is provided so that air escapes through the opening 52 when the tapping member 50 rotates. Other configurations of the tapping member 50 are the same as those of the tapping member 20.

  In the said embodiment, the example in which the hitting member was directly attached to the rotating shaft was shown. However, the hitting member may be attached to the rotating shaft via another member as long as it is configured to rotate with the rotating shaft.

  In the above embodiment, an example in which a plurality of hitting members are provided has been shown. However, only one hitting member may be provided.

  In the said embodiment, the case where a rotating shaft and an accommodating part rotate in the mutually opposite direction was illustrated. However, the rotation direction of the housing portion may be the same as the rotation direction of the rotation shaft. In that case, it is preferable that the rotational speed of the rotating shaft is larger than the rotational speed of the accommodating portion. However, it is not essential to have a configuration in which the housing portion rotates.

  In the said embodiment, the accommodating part showed the example which is cylindrical shape. However, the accommodating portion may be tapered. Moreover, in the said embodiment, the example in which the rotating shaft and the central axis of an accommodating part were horizontal was shown. However, the rotation axis and the central axis of the housing portion may be inclined with respect to the horizontal.

  In the said embodiment, the protrusion 32 which has a substantially triangular cross section was illustrated. However, the protrusion 32 may be flat as shown in FIG. Moreover, in the said embodiment, the example which the protrusion 32 extended over the substantially whole of the center axis direction of the accommodating part was shown. However, the protrusion 32 may extend only in a part of the housing portion in the central axis direction.

  In the said embodiment, the example in which four protrusions were provided on the inner peripheral surface of the accommodating part was shown. However, the number of protrusions can be any number greater than or equal to one. However, it is not essential to provide protrusions in the housing portion.
