Description

  The present invention relates to a waste container for storing wastes such as used sanitary napkins or other wastes by pushing them into a waste container.

  In Patent Document 1, a frame member having an opening on the upper surface and a lid member provided so as to open or close the opening of the frame member are provided in an upper part of a container for storing garbage. And a tray that rotates in conjunction with the opening / closing operation of the lid member and operates to close the opening of the frame member when the lid member is opened. The lid member and the tray are integrally formed, and a plurality of slits penetrating from the front surface to the back surface are formed in the tray. Further, when the tray closes at the end of the closing operation of the lid member, a plurality of plate members are formed that enter the respective slits and protrude from the back side of the tray to the front side.

  Since the lid member and the tray are integrally formed, even when the lid member is opened, the tray temporarily closes the opening of the frame member, which is a dust receiving port, so the inside of the container cannot be seen from the outside. . The user can throw away the trash in peace because the trash can never be seen by a later user. Further, the later user does not feel uncomfortable by seeing the garbage thrown away by the previous user.

  Furthermore, even when dust with adhesiveness is stuck to the tray, the plate member is inserted into the slit formed in the tray and protrudes from the tray when the lid member is closed. It can be peeled off and securely stored in the storage container. Therefore, the garbage thrown away by the previous user remains unattached to the receiving tray and is not exposed to the subsequent user.

  Patent Document 2 discloses a waste container device that stores odorous waste, such as used paper diapers and sanitary napkins, which are likely to generate odor, after sealing with a film. That is, the package device is provided on the upper part of the waste container that stores the waste. The package device is arranged in parallel with each other so as to be in contact with each other via two film supply rollers that are arranged in parallel to be spaced apart from each other and supply two films, and each film drawn from each film supply roller. And two waste enclosing rollers arranged in parallel. Furthermore, the two friction rollers that are driven to rotate so that the waste that has passed between the two waste enclosing rollers is drawn downward in a state of being encapsulated between the two films are for enclosing the two wastes. It is provided below the roller.

  Therefore, it is possible to dispose of odor generating waste sealed with a film. At this time, the film after the waste is sealed is pulled downward by two friction rollers provided below the two waste enclosing rollers. Therefore, the waste sealed with the film can be prevented from being caught by the waste enclosing roller. Moreover, since the friction roller is provided with a means for making the surface frictional force higher than that of the waste sealing roller, the friction roller has a strong pulling force and a strong force against the waste already stored in the waste container. Press to contain new waste. As a result, the waste storage rate in the waste storage unit is increased.

Japanese Patent No. 40056494 WO2010 / 150763

  In the technique of Patent Document 1, since dust is simply dropped into the storage container, the dust is stored in a substantially mountain shape in the storage container with the dropping position as the center. Therefore, even if there is a space that can be accommodated, when the vicinity of the top of the dust accumulated in a substantially mountain shape reaches the opening of the frame member, when the lid member is opened / closed, the vicinity of the top of the dust comes into contact with it, thereby hindering the opening / closing operation It is necessary to collect garbage at that time. Since this type of trash can is installed in stations and department store toilets used by many people, maintenance work such as collection of trash is performed by contractors. In order to facilitate the maintenance work and reduce the cost, it is preferable to increase the time interval of the collection work of the waste in the storage container as much as possible. For that purpose, the waste storage rate in the storage container can be improved. Desired.

  In the technique of Patent Document 2, odorous waste can be sealed and disposed with a film, and the waste storage rate in the waste storage portion can be increased by two friction rollers. However, since the package device is a complicated mechanism, there is a problem in terms of cost, and it is difficult to reduce the size, and it is difficult to install when the space in the toilet is small.

  DISCLOSURE OF THE INVENTION The present invention has been made in view of the above, and can be made compact so that it can be installed even in a small installation space, and the waste that can improve the waste storage rate in the waste storage unit It is an object to provide an object storage device.

  In order to solve the above-mentioned problems, a waste container of the present invention includes a waste container that stores waste, and a loading device that is disposed above the waste container and pushes the waste to the waste container. And the loading device is disposed so as to be rotatably opposed to sandwich the waste, and elastically deforms along the shape of the waste when the waste passes. And a pair of loading rollers made of a rubber member that pushes the waste into the waste container so as to draw the waste in the rotation direction by the friction force, and a drive unit that rotates at least one of the pair of loading rollers. It is characterized by having.

  A transmission roller is provided on at least one end in the axial direction of one of the pair of loading rollers, and the driving unit includes a driving roller that contacts the surface of the transmission roller and transmits the rotation by frictional force. It can be configured. Further, in both of the pair of loading rollers, a transmission roller is provided at least on one end side in the axial direction of each loading roller, and the drive unit contacts the surface of the transmission roller located on one loading roller side. Thus, a driving roller that transmits rotation by frictional force can be provided. When such a transmission roller is provided, each of the loading rollers has a central cylindrical portion in which a through-hole through which the rotation shaft is inserted is formed, and a plurality of supports extending radially from the central cylindrical portion toward the outer peripheral surface. The support roller is deformed to hold the waste when the outer peripheral surface is pressed by the waste to be charged, and the transmission roller includes the loading roller. It is preferable to have a structure that has a through hole that communicates with a through hole formed in a central cylindrical portion of the roller and through which the rotating shaft is inserted, and rotates together with the loading roller.

On the other hand, each loading roller has a pair of rotating rollers arranged at predetermined intervals in the axial direction, and a cylindrical rubber member having both ends in the axial direction supported by the pair of rotating rollers. The cylindrical rubber members may be configured such that at least a part of the cylindrical rubber members can contact each other and transmit rotation by frictional force.
One of the cylindrical rubber member and each of the rotating rollers has an engaging protrusion that protrudes toward the other, and the other is formed with an engaging groove that engages with the engaging protrusion. It is preferable to have a configuration.

  When the axial direction of each loading roller is the width direction of the waste container, it is preferable that the waste container has a narrow thin shape with the direction perpendicular to the width direction as the longitudinal direction.

  According to the present invention, when waste is thrown between a pair of loading rollers that are rotated by a drive unit in the loading device, the pair of loading rollers are made of rubber members, so that they deform along the outline of the waste. It rotates while being sandwiched, and the waste can be dropped and accommodated by being drawn into the waste accommodating portion by the frictional force of the surface. Even if the waste accumulates in the waste container and forms a substantially mountain shape and reaches below the pair of loading rollers, the friction of the outer peripheral surface of the loading roller that deforms the thrown-in waste along its outer shape. Pull in the direction of rotation by force. At this time, if new waste comes into contact with the waste that has already accumulated, the new waste is not directly under the pair of loading rollers, but from diagonally downward to further laterally due to the frictional force of the loading roller. It is pushed out as if towed. Therefore, by pulling in the waste thrown in later by the frictional force of the rubber member, it can be pushed out not only on the accumulated waste but also into a space that can still be accommodated. That is, waste can be pushed out in a direction perpendicular to the axial direction, which is an extension of the rotation direction of the loading roller. Therefore, even if the shape of the waste container is formed in a thin shape in which the direction perpendicular to the axial direction of the loading roller is the longitudinal direction, waste can be stored in every corner and installed in a narrow space in the indoor space. Suitable for

  Moreover, it is preferable that the rotational force of the drive unit is transmitted by a frictional force. When a load greater than the frictional force is applied for some reason, the drive roller of the drive unit slips, and an excessive load on the drive unit can be prevented. be able to.

  Hereinafter, the waste container of the present invention will be described in more detail based on the embodiments shown in the drawings. FIG. 1 shows a schematic configuration of a loading device in a waste container according to an embodiment of the present invention. FIG. 2 shows the overall configuration of the waste container.

  As shown in FIG. 2, the waste container 10 of the present embodiment is disposed in a waste container 11 that stores waste, and the waste container 11 is disposed above the waste container 11 so that the waste is transferred to the waste container 11. And an extruding loading device 20.

  In the present embodiment, the waste container 11 has a box shape with an open top surface. For example, the waste container 11 has a length of 400 mm, a width of 120 mm, a height of 400 mm, and a volume of about 19 L (liter). That's it. The type of waste is not limited, but it is assumed that it is desired not to be exposed to human eyes after disposal, typically used sanitary products (such as napkins).

  As shown in FIG. 1, the loading device 20 includes a lid-shaped housing 21 that covers the opening on the upper surface of the waste container 11, and the housing 21 is detachably provided on the waste container 11. The housing 21 has an upper wall portion 21a and a side wall portion 21b, and a waste input port 22 for inputting waste into an appropriate position of the upper wall portion 21a, in this embodiment, at a substantially central position in the longitudinal direction. Is provided. Also, below the upper wall portion 21a of the housing 21, a pair of elastically deformable loading rollers 23 and 24 opposed so as to rotate with the waste thrown in from the waste throw-in port 22 interposed therebetween, and the loading roller And a drive unit 30 that rotates the motors 23 and 24. In addition, the formation position of the waste input port 22 is arbitrary, and considering the mutual positional relationship with the loading rollers 23 and 24, if waste can be supplied between the loading rollers 23 and 24, for example, the upper wall portion 21a It can also be provided near the end.

  The loading rollers 23 and 24 are rotatably supported by bearings provided on opposite side wall portions 21 b and 21 b of the housing 21 by a rotation shaft 27. The loading rollers 23 and 24 have the same structure, and transmission rollers 25a and 25b or 26a and 26b each having a rotation transmission friction surface on the outer periphery are disposed at the end portions in the axial direction of the loading rollers 23 and 24, respectively. ing. This rotation transmission friction surface may be set by forming the transmission rollers 25a, 25b or 26a, 26b themselves using a material having a predetermined frictional force, for example, a rubber member such as silicone rubber. It may be set by attaching a rubber member such as silicone rubber around the rollers 25a, 25b or 26a, 26b. Further, the transmission roller 25a and the transmission roller 26a facing each other in the pair of loading rollers 23 and 24 are in contact with each other, and the transmission roller 25b and the transmission roller 26b are in contact with each other. Is transmitted to the loading roller 24.

  In FIG. 1, transmission rollers 25 a and 25 b are provided at both ends of the loading roller 23, and transmission rollers 26 a and 26 b are provided at both ends of the loading roller 24. However, if the rotational force of the loading roller 23 can be transmitted to the loading roller 24, for example, the transmission roller 25a and the transmission roller 26a may be provided only at one end on the same side of the loading rollers 23 and 24.

  As shown in FIG. 1, the rotation shaft 27 has a quadrangular shape with a cross section perpendicular to the axial direction. On the other hand, the loading rollers 23 and 24 are each provided with a through-hole 28 having a quadrangular section for insertion through the rotary shaft 27 at the center of rotation.

Further, the transmission rollers 25a and 25b are provided with a through-hole 29 having a quadrangular section in the center of rotation through the rotation shaft 27 and communicating with the through-hole 28 of the loading rollers 3 and 24. Accordingly, the loading roller 23 and the transmission rollers 25 a and 25 b at both ends rotate integrally with each other via the rotary shaft 27. Similarly, the transmission rollers 26a and 26b are provided with a through-hole 29 having a quadrangular section for insertion through the rotating shaft 27 at the center of rotation. Therefore, the loading roller 24 and the transmission rollers 26 a and 26 b at both ends rotate integrally via the rotation shaft 27.
The material of the transmission rollers 25a, 25b, 26a, and 26b may be any material that allows a predetermined frictional force to function. In this embodiment, silicone rubber is used, but the material is not limited to this.

Here, each of the loading rollers 23 and 24 is made of an elastically deformable material, preferably a rubber member, so as to be elastically deformable along the external shape of the waste when the waste is sandwiched. In the form, it has a structure as shown in FIG. That is, the loading rollers 23 and 24 are hollow with a plurality of support portions 23c and 24c extending radially from the central cylindrical portions 23a and 24a having through holes 28 through which the rotary shaft 27 is inserted toward the outer peripheral surfaces 23b and 24b. This is the structure. In the present embodiment, there are six support portions 23c and 24c, respectively, but the degree of elastic deformation of the outer peripheral surfaces 23b and 24b varies depending on the number of the support portions 23c and 24c, that is, the outer peripheral surface 23b. , 24b is pressed by waste, the outer peripheral surfaces 23b, 24b themselves are elastically deformed, and the support portions 23c, 24c are elastically deformed so as to be bent. Therefore, the number of support portions 23c, 24c is adjusted. Thus, the degree of elastic deformation can be adjusted to a desired level. Moreover, although the support parts 23c and 24c may be formed over the whole longitudinal direction of the loading rollers 23 and 24, you may make it form partially along a longitudinal direction.
In this embodiment, the material of the loading rollers 23 and 24 is preferably silicone rubber as in the case of the transmission rollers 25a, 25b, 26a, and 26b, but is not limited thereto.

  The drive unit 30 includes a motor 31 and a drive roller 32 supported by a bracket 33 attached to the housing 21. The driving roller 32 is connected to the rotation shaft of the motor 31, contacts the transmission roller 25 a of one loading roller 23, and transmits rotation by frictional force. In order to exert a predetermined frictional force, silicone rubber is used in the present embodiment, but the present invention is not limited to this.

  Further, as shown in FIG. 2, an operation switch 34 for turning on / off the rotational drive of the motor 31 is provided on the upper wall portion 21a of the housing 21. Various types of switches can be used as the operation switch. For example, a sensor that detects waste input to the waste input port 22 is disposed near the waste input port 22, and the rotation drive of the motor 31 is turned on by the detection signal of the sensor, so that the waste is loaded into the loading roller 23. , 24 can be set to turn off the rotational drive of the motor 31 after moving to the waste container 11.

Next, the effect | action in said waste accommodating apparatus 10 is demonstrated.
When waste is input from the waste input port 22 and the operation switch 34 is turned ON (or when it is detected by the sensor), the motor 31 is rotated and the driving roller 32 in FIG. Rotate around. The loading roller 23 and the transmission roller 25b rotate counterclockwise in FIG. 1 through the transmission roller 25a that is in contact with the driving roller 32. The loading roller 24 rotates clockwise in FIG. 1 via a transmission roller 26a that contacts the transmission roller 25a and a transmission roller 26b that contacts the transmission roller 25b. That is, as shown in FIG. 4, the pair of loading rollers 23 and 24 rotate so as to move downward with the waste sandwiched therebetween.

  When the waste W is sandwiched between the loading rollers 23 and 24, the outer peripheral surfaces 23b and 24b of the loading rollers 23 and 24 are deformed and sandwiched along the outer shape of the waste W as shown in FIGS. The waste W is moved so as to be drawn downward by the frictional force of the surfaces of the loading rollers 23 and 24 and is accommodated in the waste accommodating portion 11.

  The waste W accumulates inside the waste container 11 and eventually reaches a position just below the pair of loading rollers 23 and 24 as shown in FIG. Nevertheless, the waste W thrown in later is pushed downward or obliquely downward by the loading rollers 23 and 24 deforming along the outer shape thereof.

  More specifically, as shown in FIG. 4, the outer peripheral surfaces 23b and 24b of the loading rollers 23 and 24 are deformed along the outer shape of the waste W, and the support portions 23c and 24c are deformed so as to bend according to the deformation. Therefore, the waste W moves in a state where it is firmly grasped by the elastic restoring force of the outer peripheral surfaces 23b, 24b and the support portions 23c, 24c of the loading rollers 23, 24 and the frictional force of the surfaces of the outer peripheral surfaces 23b, 24b. To do. Therefore, at the position where the outer peripheral surfaces of the rotating loading rollers 23 and 24 are separated from each other, as shown in FIG. 5C, the waste W to be thrown in is the waste W that has already accumulated in a substantially mountain shape. It is thrown to touch the top and hold it down. As a result, the accumulated waste W is scattered in the vacant space. Alternatively, when the waste W already accumulated in a substantially mountain shape is not pushed in much, the waste W to be thrown in is the outer peripheral surface 23b, 24b of one of the loading rollers 23 or 24. The loading roller 23 or 24 is fed in the direction of rotation so that it is attracted to it by the frictional force of the surface, that is, the vicinity of the top of the deposited waste part W becomes an obstacle and escapes from it. As indicated by a two-dot chain line 5 (d), the material is extruded obliquely downward or laterally. In this way, when the waste W input later is pushed in, the input waste W itself and / or the waste W that has already accumulated is changed from the state of FIG. 6 to FIG. Since it is pushed out to the space which can be accommodated in the waste accommodating part 11, the accommodation rate of the waste W in the waste accommodating part 11 improves. Therefore, when the axial direction of the loading rollers 23 and 24 is the width direction of the waste container, the direction (longitudinal direction) orthogonal to the width direction of the waste container 11 (the axial direction of the loading rollers 23 and 24). ), The waste W can be sent out. That is, it is a case where the installation space in the width direction is installed in a narrow place because the waste W is sent out so as to be scattered along the longitudinal direction of the waste container 11, not directly under the loading rollers 23 and 24. Also, a desired amount of waste W can be accommodated.

  Moreover, since it has such an action, it is assumed that the width is the same to accommodate the same amount of waste as compared with the structure having no loading rollers 23 and 24 according to the present embodiment. The form can be a structure having a lower height, and this embodiment is particularly suitable for a place where there is no room in the space in the height direction.

  Here, a verification experiment of the accommodation amount was performed using a sample of a sanitary napkin having a size of length 100 (mm) × width 85 (mm) × thickness 15 (mm). The waste storage unit 11 used in the experiment was thin and narrow with a width of 400 mm, a width of 120 mm, a height of 400 mm, and a volume of about 19 L (liter). As a result, 140 waste samples could be put into the waste container 11. Further, when a similar experiment was performed using the waste container 11 having a length of 560 mm, a width of 120 mm, a height of 400 mm, and a volume of about 27 L (liter), 200 waste samples could be placed.

  From these things, according to this embodiment, even if the waste container 11 is narrow, more waste W can be thrown in compared with the past. Therefore, a sufficient amount of waste W can be accommodated even when the more compact waste storage device 10 of the present embodiment is disposed in a narrow installation space, for example, between a Western-style toilet and a wall. Can do. Therefore, the time interval of the recovery operation of the waste W stored in the waste storage unit 11 can be increased, and the maintenance operation can be facilitated and the maintenance cost can be reduced.

  Further, since the configuration is such that the waste W is pushed into the waste storage unit 11 using the frictional force and elastic deformation of the two loading rollers 23 and 24, the configuration is very simple. That is, since it is only necessary to provide the drive unit 30 other than the loading rollers 23 and 24, if the loading rollers 23 and 24 have an axial length corresponding to the size of the waste W to be accommodated, the waste The storage portion 11 can be thinned to a width that is about the same as the axial length of the loading rollers 23 and 24. In the present embodiment, the loading rollers 23 and 24 are arranged so that the axial direction is orthogonal to the longitudinal direction of the waste storage unit 11, but depending on the diameter of the loading rollers 23 and 24, the waste storage is performed. It is also possible to arrange the two loading rollers 23 and 24 along the longitudinal direction of the portion 11. In this case, the waste storage unit 11 can be thinned to a width that matches the diameter of the two loading rollers 23 and 24.

  In addition, the rotational force of the motor 31 in the driving unit 30 is transmitted through the frictional force between the driving roller 32 and the transmission roller 25a of one loading roller 23, and the other loading roller 24 is also in contact with each other. Rotation is transmitted by the frictional force of 25a and the transmission roller 26a, and the transmission roller 25b and the transmission roller 26b. Therefore, if a load greater than the frictional force is applied for some reason, the drive roller 32 and the transmission roller 25a, or the transmission roller 25a and the transmission roller 26a that are in contact with each other, slip on the transmission roller 25b and the transmission roller 26b. Even when an article is thrown in, it is suitable for preventing damage to the thrown-in article and the drive unit 30.

  8 and 9 are diagrams for explaining loading rollers 230 and 240 according to another embodiment. The loading rollers 230 and 240 have a pair of rotating rollers 232, 233 or 242 and 243 arranged at predetermined intervals in the axial direction, and straddle between the pair of rotating rollers 232 and 233 or between 242 and 243. As described above, the cylindrical rubber member 231 or 241 is supported. The cylindrical rubber members 231 and 241 may be formed of, for example, silicone rubber and may be pre-molded into a cylindrical shape, or may be cylindrical by fixing edges of a substantially rectangular shape. May be attached.

  Rotating shafts 270 and 270 are inserted between the pair of rotating rollers 232 and 233 or 242 and 243, and the loading rollers 230 and 240 are rotated by the rotation of the rotating shafts 270 and 270. At this time, since the cylindrical rubber members 231 and 241 are in contact with each other, the driving roller of the driving unit is in contact with one of the cylindrical rubber members 231 or 241, If 241 is rotated, the other rotates with it.

  In the present embodiment, the cylindrical rubber members 231 and 241 are supported in a cylindrical shape by the pair of rotating rollers 232 and 233 or 242 and 243, respectively, but the rotation shafts 270 and 270 and the cylindrical rubber members 231 and 241 There are no members (such as the support portions 23c and 24c in the above embodiment) in the circumferential direction. Therefore, it becomes easier to deform along the outer surface of the waste when coming into contact with the waste, that is, the contact area with the waste becomes larger than that in the above embodiment, and the cylindrical rubber members 231 and 241 and the waste The frictional force between is also increased. Therefore, it becomes easier to disperse in the longitudinal direction of the waste storage part 11, and it contributes to the improvement of a storage rate. Further, since the structure is simpler than the loading rollers 23 and 24 of the above embodiment, the manufacturing cost can be reduced.

  However, as shown in FIG. 9, the cylindrical rubber members 231 and 241 are engaged protrusions 231a, 241a and 231b and 241b that protrude toward the respective peripheral surfaces of the respective rotating rollers 232, 233 and 242, 243. Is preferably formed on at least a part of the inner periphery, and more preferably on the entire inner periphery. The rotating rollers 232, 233, 242, and 243 are engaged with the engaging protrusions 231a, 241a, 231b, and 241b so that the engaging protrusions 231a, 241a, 231b, and 241b are engaged. Grooves 232a, 242a and 233a, 243a are formed on the outer peripheral surface.

  With such a configuration, when the waste passes between the cylindrical rubber members 231 and 241, the waste is deformed along the outer surface of the waste, that is, the peripheral surfaces of the cylindrical rubber members 231 and 241 are inside. At this time, the engaging protrusions 231a, 241a and 231b, 241b of the cylindrical rubber members 231 and 241 are engaged with the engaging grooves 232a, 242a and 233a, 243a. Thereby, even if it deform | transforms so that the longitudinal direction approximate center part of the cylindrical rubber members 231 and 241 may be dented, it can suppress coming off from the rotating rollers 232,233, 242,243. In other words, even if a force for deforming the cylindrical rubber members 231 and 241 is applied when the waste passes, the engaging protrusions 231a, 241a and 231b and 241b are engaged with the engaging grooves 232a, 242a and 233a and 243a. Since the combined state remains, the waste can be reliably sandwiched by the elastic reaction force of the cylindrical rubber members 231 and 241.

  Although not shown, as long as the elastic reaction force can be applied and the waste can be sandwiched, engaging protrusions are formed on the outer peripheral surfaces of the rotating rollers 232, 233, 242, and 243, and cylindrical rubber is formed. It is also possible to employ a configuration in which an engagement groove that engages with the engagement protrusion is formed on the inner periphery of each end of the members 231 and 241. Further, as long as each end portion of the cylindrical rubber members 231 and 241 can be engaged with the rotating rollers 232, 233 and 242, 243, other engaging means can be used.
