Description

  The present invention generally relates to a transport device that transports a container (such as a hook), and more particularly to a transport device that includes a container reversal operation.

  Japanese Patent Laid-Open No. 9-313347 discloses a transport device configured to place a used container (for example, a pot) on a conveyor and transport the container toward the downstream side, and wash the pot in the middle of the transport. Patent Document 1) discloses this. In the conveying apparatus disclosed in Patent Document 1, the hook placed on the conveyor with the surface facing upward is reversed by the reversing mechanism and placed on the conveyor with the surface facing downward. After that, it is cleaned by a cleaning mechanism.

  The reversing mechanism responsible for the reversing operation with respect to the hook is constituted by a reversing arm having an F-shaped cross section. The reversing arm is arranged so that the open end of the U-shaped cross section faces the handle of the shuttle that is conveyed toward the reversing arm. As the shuttle advances toward the downstream side, the hook is inserted into the U-shaped portion of the reversing arm and engaged with the reversing arm. Thereafter, when the reversing arm rotates 180 degrees, the hook engaged with the reversing arm is placed on the conveyor with the surface facing downward.

JP-A-9-313347

However, there are various problems in the transport apparatus according to the above prior art.
First of all, since the positional relationship between the reversing arm and the hook that is placed and transported on the conveyor is not always constant, the position of the handle of the hook and the U-shaped opening of the reversing arm are open. There may be a deviation between the end positions. In this case, since the two cannot be properly engaged, there is a possibility that the hook is not properly reversed.
Second, the reversing arm can hold and reverse the hook by engaging with the handle of the hook. Therefore, the hook that can be reversed by the reversing arm is limited to a hook having a predetermined shape (particularly the shape of the handle). For example, a special pot such as a round pot cannot be used.
Furthermore, since the conveyance of the shuttle is realized by a conveyor, a motor roller, a motor, and the like, the required cost increases.
In general, the hook and the lid are used as a set. However, Patent Document 1 does not specify a configuration that serves both as a hook conveying line and a lid conveying line, and therefore the lid conveying line is provided separately from the hook conveying line. Conceivable. Therefore, the required cost is further increased.

  The present invention has been made for the purpose of providing a transport apparatus capable of addressing at least one of such problems.

  The transport device according to the present invention is a transport device for transporting a container in the transport direction, and is turned in a row along the transport direction between two side walls facing each other with a predetermined interval therebetween. Formed by a plurality of upper rollers that are freely arranged and a plurality of lower rollers that are rotatably arranged in a line along the transport direction so as to face the plurality of upper rollers between the two side walls. And a box-shaped rotating body configured to store a container in a storage area surrounded by the two side walls, the upper roller, and the lower roller, and the rotating body is rotated around a central axis. It is characterized by comprising supporting means for supporting the rotating body so as to be free, and rotation control means for rotating the rotating body attached to the supporting means.

  According to the present invention, since the reversing operation of the container is realized by reversing the rotating body that accommodates the entire container, the container of any type can be reliably and stably reversed while suppressing the required cost. be able to.

Generally speaking, the shuttle that has been transported by the upstream transport device 120 is reversed by the main transport device 110 and then transported to another cleaning device provided downstream (not shown) by the downstream transport device 130. . On the other hand, the lid that has been transported by the upstream transport device 120 passes through the main transport device 110 without being inverted, and is transported by the downstream transport device 130 to another cleaning device (not shown) in the same manner as the shuttle.

2. As shown in FIG. 1, the upstream conveyance device 120 includes two frames 122 extending parallel to each other along the conveyance direction, and a plurality of base members attached to the frame 122 and extending in the vertical direction. 124 and a plurality of rollers 126 that are disposed between the two frames 122 so as to be spaced apart from each other and are attached so as to be rotatable with respect to the frame 122.
In FIG. 1, only a part of the upstream conveyance device 120 is shown, but actually, the upstream conveyance device 120 further extends toward the upstream side.
Each roller 126 has a columnar shape or a cylindrical shape as a whole. A plane connecting the upper end surfaces of the rollers 126 (that is, a mounting surface on which the shuttle and the lid are mounted) is a single horizontal surface. When the shuttle or lid placed on the roller 126 is pressed toward the downstream side in the transport direction by an operator (not shown), the roller 126 contacting the shuttle or the lid is rotated, so that the roller 126 is moved downstream. It is conveyed toward the side.

3. Configuration of Main Transfer Device 110 The main transfer device 110 will be described with reference to FIGS. 2 and 3 in addition to FIG.
FIG. 2 is a cross-sectional view schematically showing the main transport device 110 shown in FIG. 1 as viewed from the upstream side (arrow A in FIG. 1) in the transport direction. FIG. 3 is a cross-sectional view schematically showing the main transport apparatus 110 shown in FIG. 1 as viewed from a direction (arrow B in FIG. 1) orthogonal to the transport direction.

  The main transfer device 110 can be broadly divided into a box-shaped rotating body 210, a casing 220 that rotatably supports the rotating body 210, and a rotating body 210 that is attached (for example, accommodated) to the casing 220. And a motor 230 to be operated.

3-1. The rotating body 210 is composed of two side walls 211 and 211 facing each other at a predetermined interval, and a plurality of the rotating bodies 210 arranged between the two side walls 211 so as to be rotatable in a line along the conveying direction. Formed in a box shape by the upper roller 212 and a plurality of lower rollers 213 arranged in a row in a row along the transport direction so as to face the upper roller 212 between the two side walls 211 Has been.

Each upper roller 212 has a columnar shape or a cylindrical shape as a whole. The plane connecting the upper end surfaces of each upper roller 212 forms one plane, and the plane connecting the lower end surfaces of each upper roller 212 also forms one plane.
Each lower roller 213 also has a generally cylindrical or cylindrical shape. The plane connecting the upper end surfaces of the lower rollers 213 forms one plane, and the plane connecting the lower end surfaces of the lower rollers 213 also forms one plane.

  Between the two adjacent upper rollers 212, support members 214 each having both ends fixed to the two side walls 211 are provided. Between the two adjacent lower rollers 213, support members 215 having both ends fixed to the two side walls 211 are provided (in FIGS. 2 and 3, the representation of the support members 214 and 215 is shown). Omitted).

  The rotating body 210 accommodates the shuttle 10 in an accommodation area 210a surrounded by two side walls 211, an upper roller 212 arranged in a row, and a lower roller 213 arranged in a row.

  Further, a stopper (stop member) 218 is provided between the two side walls 211 in the vicinity of the downstream side in the transport direction. In the present embodiment, for example, two rod-like members 218 are used as the stopper 218. As is apparent from FIG. 1A, one end and the other end of each bar member 218 are fixed to the inner surface of each side wall 211. Each rod-shaped member 218 abuts against the shuttle 10 mounted on the lower roller 213 (particularly as shown in FIG. 3) to prevent further movement of the shuttle 10 downstream, The height from the lower roller 213 is adjusted so as not to contact the lid (not shown) placed on the top (lower than the hook 10) and to allow further movement of the lid downstream. Has been.

  Shafts 217a and 217b are fixed to outer surfaces 211a and 211b of each side wall 211 by fixing members 216a and 216b, respectively (as shown in FIG. 2). The central axes of these shafts 217a and 217b are on the same axis.

3-2. The casing 220 of the casing 220 supports the rotating body 210 so as to be rotatable. The housing 220 includes a base 221 having a rectangular parallelepiped shape disposed on the ground, and two boxes 222 and 223 fixed to the base 221 so as to face each other. Specifically, the base 221 extends its side walls 221a and 221b upward. Boxes 222 and 223 are fixed to the side walls 221a and 221b, respectively. Thereby, the box 222 faces the outer surface 211 a of the side wall 211 of the rotating body 210, and the box 223 faces the outer surface 211 b of the rotating body 210.

  As shown in FIG. 2, a bearing 222 a is accommodated and fixed inside the box body 222. The bearing 222a supports the shaft 217a of the rotating body 210 so as to be rotatable. Similarly, a bearing 223 a is accommodated and fixed inside the box 223. The bearing 223a supports the shaft 217b of the rotating body 210 so as to be rotatable. Thereby, the rotating body 210 can rotate around the shafts 217a and 217b as the central axis.

  As shown in FIG. 2, the housing 220 is open above the rotating body 210. In addition, the housing 220 has a sufficient space below the rotating body 210 so as not to hinder the rotation of the rotating body 210. Therefore, when the rotating body 210 rotates, the rotating body 210 is not obstructed by the housing 220 as shown in FIG.

3-3. A motor 230 that rotates the rotating body 210 is housed and fixed inside the component box 222 of the motor 230. The shaft 231 of the motor 230 is mechanically connected to the shaft 217a of the rotating body 210. The control unit that controls the rotation of the motor 230 and the operation panel connected to the control unit are not shown, but conventional ones can be used. The operation panel (not shown) can be provided on the outer surface of the box 222, for example. In response to the operator performing a predetermined pressing operation on the operation panel, the control unit (not shown) rotates the shaft 231 of the motor 230 in the normal direction or the reverse direction, so that the rotating body 210 rotates in the normal direction or the reverse direction. It is done.

  In this embodiment, the case where the motor 230, the control unit (not shown), and the operation panel (not shown) are attached to the box 222 has been described. However, these components are attached to the box 223. Alternatively, the boxes 222 and 223 may be provided independently.

4). As shown in FIG. 1, the downstream transfer device 130 is disposed on a sink 131 having a rectangular parallelepiped shape, a base member 132 attached to the bottom surface of the sink 131 and extending in the vertical direction, and an upper surface of the sink 131. A transport unit 133.

The conveyance unit 133 is arranged so as to be rotatable with respect to the frame 134, with two frames 134 extending parallel to each other along the conveyance direction, and being spaced from each other between the two frames 134. And a plurality of rollers 135. Each roller 135 has a columnar shape or a cylindrical shape as a whole.
Although not shown in FIG. 1, a cleaning device that ejects cleaning liquid from below to a pot or lid placed on the roller 135 may be mounted in the sink 131. In this case, the downstream conveyance device 130 can not only convey the hook and lid received from the main conveyance device 110 but also can wash them.

  A plane connecting the upper end surfaces of the rollers 135 (that is, a mounting surface on which the shuttle and the lid are mounted) is a single horizontal surface. When the shuttle and lid placed on the roller 135 are pressed toward the downstream side in the transport direction by an operator (not shown), the roller 135 that contacts the shuttle or the lid is rotated, so that the roller 135 is moved downstream. It is conveyed toward the side.

5. The operation of the conveying device 100 having the configuration described as the operation described above of the transfer device 100, in addition to FIGS. 1 to 3 previously used, will be described with reference to FIGS.
4 to 6 are schematic diagrams illustrating an operation in which the transport device 100 according to the embodiment of the present invention transports the shuttle 10. FIG. 7 is a schematic diagram illustrating an operation in which the transport apparatus 100 according to the embodiment of the present invention transports the lid 20.

First, referring to FIG. 4, the main transport device 110 is disposed adjacent to the downstream side of the upstream transport device 120, and the downstream transport device 130 is disposed adjacent to the downstream side of the main transport device 110.
A plane connecting the upper end surfaces of the rollers 126 of the upstream conveying device 120, that is, the placement surface X formed by the rollers 126 is a horizontal plane. A plane connecting the upper end surfaces of the rollers 135 of the downstream conveyance device 130, that is, a placement surface Z formed by the rollers 135 is also a horizontal plane.

FIG. 4 shows a state where the rotating body 210 of the main transport device 110 is stationary in the first state (normal state). That is, when the rotating body 210 is in the first state, the lower roller 213 is positioned below the upper roller 212. When the rotating body 210 is in the first state, the plane connecting the upper end surfaces of the lower rollers 213, that is, the mounting surface Y formed by the lower rollers 213 is an inclined surface that descends toward the downstream side in the transport direction. It has become.
Compared with FIG. 4, FIG. 6 shows a state where the rotating body 210 of the main transfer device 110 is stationary in the second state (reversed state). That is, when the rotating body 210 is in the second state, the upper roller 212 is positioned below the lower roller 213. When the rotating body 210 is in the second state, the plane connecting the lower end surfaces of the upper rollers 212, that is, the mounting surface Y ′ formed by the upper rollers 212 is inclined downward toward the downstream side in the transport direction. It is a surface.

Returning to FIG. 4, the relationship between the placement surface Y of the main transport device 110 and the placement surface X of the upstream transport device 120 will be described. The placement surface X of the upstream transport device 120 is the (first) of the main transport device 110. The heights of the mounting surface X and the mounting surface Y are set so that the upstream end Y _{1 of the} mounting surface Y) of the rotating body 210 in one state has substantially the same height.
On the other hand, returning to FIG. 6, the relationship between the placement surface Y ′ of the main transport device 110 and the placement surface Z of the downstream transport device 130 will be described. The placement surface Z of the downstream transport device 130 is the main transport device 110. The height of the mounting surface Z and the mounting surface Y ′ so that the end Y ′ ₂ on the downstream side of the mounting surface Y ′ (of the rotating body 210 in the second state) has substantially the same height. Is set.

  First, referring to FIG. 4, the shuttle 10 is placed on the roller 126 of the upstream conveying device 120. When the operator presses the shuttle 10 toward the downstream side in the transport direction, the roller 126 that contacts the bottom surface of the shuttle 10 rotates, thereby transporting the shuttle 10 toward the downstream side. When the shuttle 10 is further transported toward the downstream side, the shuttle 10 advances into the accommodation area 210a of the rotating body 210 (in the first state) of the main transport device 110. In addition, the mounting surface X of the upstream conveying device 120 can be formed to be an inclined surface that descends toward the downstream side. Thereby, the force required for the operator to move the shuttle 10 to the downstream side can be reduced.

  The shuttle 10 that has advanced into the housing area 210 a of the rotating body 210 is placed on the lower roller 213. As described above, when the rotating body 210 is in the first state, the placement surface Y formed by each lower roller 213 is inclined so as to descend toward the downstream side. Therefore, the shuttle 10 entering the inside of the accommodation area 210a of the rotating body 210 further proceeds toward the downstream side under the influence of the mounting surface Y being inclined. The shuttle 10 that continues to advance as described above comes into contact with a stopper 218 provided in the accommodation area 210a and stops.

  Next, the operator gives an instruction to cause the motor 230 housed in the box body 222 shown in FIG. 2 to rotate normally (by operating an operation panel (not shown)). (Not shown) When the control unit responding to this causes the motor 230 to rotate normally, as shown in FIG. 5, the rotating body 210 also rotates normally (rotates counterclockwise on the paper surface) by the normal rotation of the motor 230.

Thereafter, the rotating body 210 stops rotating and enters a stationary second state (inverted state) as shown in FIG. When the rotator 210 is in the second state, as described above, the downstream end Y ′ ₂ of the mounting surface Y ′ has substantially the same height as the mounting surface Z of the downstream transport device 130. Note that the transition of the rotating body 210 from the first state to the second state is realized by causing the motor 230 to rotate forward by, for example, a predetermined amount of rotation.

  As shown in FIG. 6, when the rotating body 210 reaches the second state, there is no longer anything that prevents the hook 10 from moving downstream on the downstream side of the hook 10 (the stopper 218 is provided with the stopper 218). Is located upstream). Further, in this state, the inclined surface Y ′ formed by each upper roller 212 is lowered toward the downstream side. Therefore, the shuttle 10 starts to move downstream due to the influence of the inclined surface Y ′ and gravity, is discharged from the accommodation area 210 a of the rotating body 210, and is placed on the roller 135 of the downstream transport device 130. And is stationary.

In the present embodiment, as the most preferred embodiment, the mounting surface Y (see FIG. 4) formed by the rotating body 210 in the first state and the rotating body 210 in the second state are formed. The mounting surface Y ′ (see FIG. 6) is configured to be substantially in the same plane. This is possible by arranging the central axis O of the rotating body 210 in the middle between the placement surface Y and the placement surface Y ′.
Thereby, the shuttle 10 inverted by the rotation of the rotating body 210 is discharged from the rotating body 210 and delivered to the downstream conveyance device 130.

  After the shuttle 10 is discharged from the rotating body 210, the control unit (not shown) reverses the motor 230 in response to an operation on the operation panel (not shown) by the operator or spontaneously. Due to the reverse rotation of the motor 230, the rotating body 210 is also reversed. Thereby, the rotating body 210 which was in the second state (FIG. 6) returns to the first state (FIG. 4).

  As described above, the shuttle 10 that has been transported to the upstream reversing device 120 with the surface facing upward is reversed by the main transport device 110 and transported to the downstream transport device 130 with the surface facing downward. . The mounting surface Z of the downstream transport device 130 can be formed to be an inclined surface that descends toward the downstream side. Thereby, the force required for the operator to move the shuttle 10 to the downstream side can be reduced.

On the other hand, the transport apparatus 100 according to the present embodiment can also serve as the transport of the shuttle 10 and the transport of the lid 20.
Referring to FIG. 7, the lid 20 placed on the roller 126 of the upstream conveyance device 120 also rolls on the roller 126 by being pressed toward the downstream side by the operator, so that the storage area of the rotating body 210 is stored. Proceed to 210a. Furthermore, it rolls on each roller 213 which forms the mounting surface Y which descend | falls toward a downstream side with dead weight. Unlike the shuttle 10, the lid 20 is not blocked by the stopper 218 from proceeding downstream. Therefore, the lid 20 leaves the accommodation area 210 a of the rotating body 210 and reaches the downstream transfer device 130.

  In the present embodiment, the case where the mounting surfaces Y and Y ′ of the rotating body 210 are inclined so as to descend toward the downstream side has been described in order to show the most preferable mode. The mounting surface Y and / or the mounting surface Y ′ of the rotator 210 is not limited to this, like the mounting surface X of the upstream transport device 120 and the mounting surface Z of the downstream transport device 130, You may comprise so that it may become horizontal.

  In the present embodiment, the case where the rotating body 210 is reversed when returning the rotating body 210 in the second state to the first state has been described as an example. However, the rotating body 210 in the second state can be further rotated forward to return to the first state.

  As described above, according to the present invention, the reversal of the container such as the hook is performed by rotating the rotating body itself that accommodates the container. Therefore, as long as the container can be accommodated in the rotating body, any container of any type and size (for example, a hook without a handle or a specially shaped container) can be reversed. In addition, since the container does not require a precise engagement relationship between the rotating body and the reversing operation, the container can be reliably and easily reversed.

  Furthermore, in the present invention, the conveyance of the container is not realized by a costly part such as a conveyor, but forms a horizontal surface or an inclined surface descending toward the downstream side. Realized by the arranged rollers. Therefore, the cost required for transporting the container can be greatly reduced, and power saving can be achieved.

  Further, according to the present invention, it is possible not only to specialize in the conveyance of one type of container, but also to convey a plurality of types of containers (for example, a pot and a lid) having different shapes. Therefore, it is possible to provide a transport apparatus that can cope with various applications while suppressing necessary costs.

  Furthermore, in the present invention, the mounting surface of the rotating body can be an inclined surface that descends toward the downstream side. Thereby, a container can perform the approach to a rotary body, and the discharge | emission from a rotary body at least partially by rolling with dead weight. Thereby, since parts, such as a conveyor and a motor, can be reduced, power saving can be achieved. In addition, the force required for the operator (pressing force on the container) can be reduced.

  In addition, the reversal of the container does not require engagement with a portion such as a handle provided in the container, and simply a locking member (stopper) provided on the downstream side of the container accommodated in the rotating body is provided on the side surface of the container. This is realized by rotating the rotating body itself in the locked state. Thereby, the possibility of damaging the container to be reversed can be suppressed.

  In the above-described embodiment, as the most preferable mode, a case has been described in which the rollers of the upstream transport device 120 and the downstream transport device 130 are provided so as to be rotatable in order to save power. However, in order to reduce the force required for the operator (pressing force on the container), at least one of the upstream conveyance device 120 and the downstream conveyance device 130 may be rotated by a motor or the like. .
