Description

  The present invention relates to a work table used when performing an operation such as attaching a label to an object such as a container filled with a liquid or the like.

  2. Description of the Related Art Conventionally, a work table having a mounting plate that is horizontal to the ground has been used for performing operations such as attaching labels to objects such as containers filled with liquids. Here, the height of the container etc. discharged from the machine for filling the container etc. with liquid etc. varies depending on the type of the machine. In some cases, the height of the discharged container or the like becomes very low. For this reason, as a work table on which an object such as a container filled with a liquid or the like is placed, a work table whose height level is positioned at, for example, the height of the operator's knee is used.

  As another type of workbench, Patent Document 1 discloses a workbench in which a frame on which an object such as a waste TV is placed can be tilted by a cylinder to which fluid pressure such as air or hydraulic pressure is supplied. Has been.

  The work table 10 according to the present embodiment is used when performing work such as attaching a label to an object such as a container filled with liquid or the like. As shown in FIGS. 1 to 3, the work table 10 according to the present embodiment supports the placement unit 30 around a placement unit 30 on which an object is placed and a shaft 39 extending in a substantially horizontal direction. 1, when the object is not placed on the placement unit 30, the placement unit 30 is maintained at the first position as shown in FIG. When the mounting unit 30 is rotated with respect to the support unit 20 in a state where an object is mounted, the mounting unit 30 moves to the second position as shown in FIG. Then, as shown in FIG. 4, the operator takes a posture toward the work table 10 from a position on the left side of the work table 10 in FIGS. 1 and 2 (that is, a right-facing posture in FIGS. 1 and 2). Then, an operation such as attaching a label to an object such as a container placed on the placement unit 30 is performed. That is, in FIGS. 1 and 2, the left part of the work table 10 is the front side for the operator, while the right part of the work table 10 is the back side for the worker. Details of each component of the work table 10 will be described below.

  The support unit 20 includes a front support member 22 and a back support member 24 provided so as to extend along the vertical direction on the front side and the back side of the work table 10, and the front support member 22 and the back support, respectively. It has the upper side connection member 26 and the lower side connection member 28 which connect the member 24 in an upper side position and a lower side position, respectively. Here, as shown in FIG. 3, when the work table 10 is viewed from the front side (that is, when the work table 10 is viewed from the left side in FIGS. 1 and 2), the front support member 22 has a pair of left and right sides. Each front-side support member 22 is made of a rod-like member extending upward in the vertical direction from the ground. Similarly, when the work table 10 is viewed from the front side, the back side support members 24 are provided in a pair of left and right, and each back side support member 24 is formed of a rod-like member extending upward in the vertical direction from the ground. . Here, when the work table 10 is viewed from above, the front support members 22 and the back support members 24 are arranged at the four corners of a virtual rectangle. Further, the upper connecting member 26 is formed of a rod-like member extending in a substantially horizontal direction for connecting each front side support member 22 and each back side support member 24 at these upper positions, and the lower connection member 28 includes The front side support member 22 and the back side support members 24 are each formed of a rod-like member extending in a substantially horizontal direction for connecting at a lower position thereof. The positions of the front support members 22, the back support members 24, the upper connection member 26, and the lower connection member 28 are fixed.

  The placement unit 30 includes a bottom member 32 that is in contact with the bottom surface of the placed object and a back member 34 that is in contact with the side surface of the placed object. It is provided so as to extend upward from the side edge (that is, the right side in FIGS. 1 and 2). In addition, a rod-shaped member 38 is attached to the bottom member 32 so as to extend downward from the bottom surface of the bottom member 32 (that is, the surface opposite to the surface on which the placed object is in contact). A shaft 39 extending in a substantially horizontal direction is provided at the lower end portion. Here, the shaft 39 is rotatably provided on the upper connecting member 26 in the support portion 20, and the rod-shaped member 38 rotates with respect to the support portion 20 around the shaft 39. Further, in the work table 10 according to the present embodiment, as shown in FIG. 1, when the object is not placed on the placement unit 30, the bottom member 32 of the placement unit 30 extends along a substantially horizontal plane. It becomes. On the other hand, when the rod-like member 38 of the placement unit 30 is rotated with respect to the support unit 20 around the shaft 39 in a state where the object is placed on the placement unit 30, the bottom member 32 is shown in FIG. Is inclined with respect to the horizontal plane. More specifically, when the mounting unit 30 is rotated with respect to the support unit 20 with the object mounted on the mounting unit 30, the bottom member 32 is within a range of 30 to 60 degrees with respect to the horizontal plane. Inclined at an angle of, preferably 45 degrees, for example. Here, since the back member 34 is provided so as to extend upward from the edge on the back side of the bottom member 32, even if the bottom member 32 is inclined with respect to the horizontal plane as shown in FIG. The object does not fall from the bottom member 32 to the back side.

  Further, as shown in FIGS. 1 to 3, a rod-shaped member 36 is attached to the bottom member 32 so as to extend downward from an edge on the near side of the bottom member 32 (that is, the left side in FIGS. 1 and 2). . Here, as shown in FIG. 3, when the work table 10 is viewed from the front side (that is, when the work table 10 is viewed from the left side in FIGS. 1 and 2), the rod-shaped member 36 is a pair of left and right. The upper end portions of the pair of left and right rod-shaped members 42 are connected to the lower end portions of the respective rod-shaped members 36 through the link members 40. Here, each rod-shaped member 42 is provided so as to extend along the vertical direction, whereas each rod-shaped member 36 is directed to the back side of the work table 10 with respect to each rod-shaped member 42 with each link member 40 as the center. And can be rotated. In addition, a slide member 46 that slides along the vertical direction with respect to each near-side support member 22 is attached to the lower end portion of each rod-like member 42. Here, when the work table 10 is viewed from the front side, the slide member 46 is provided in a pair of left and right. Further, each slide member 46 is formed in a cylindrical shape, and each rod-like front support member 22 penetrates the hollow portion of each slide member 46. In the state shown in FIG. 1, the placement unit 30 (more precisely, the object placed on the placement unit 30) is pushed to the back side (that is, rightward in FIG. 1) by the operator. 1, each slide member 46 moves upward in the vertical direction along each front-side support member 22, and each rod-like member 36 moves in the clockwise direction in FIG. 1 with respect to each rod-like member 42 around the link member 40. Rotate to. At the same time, each rod-shaped member 38 rotates about the shaft 39 in the clockwise direction in FIG. Thereby, the mounting part 30 moves to the second position as shown in FIG. 2, and the bottom member 32 of the mounting part 30 is inclined with respect to the horizontal plane. In the present embodiment, the mounting portion 30 can be rotated about the shaft 39 by combining the rod-shaped members 36, the link members 40, the rod-shaped members 42, and the slide members 46. A link mechanism 48 that connects the portion 30 and the support portion 20 is configured.

  Here, when each slide member 46 moves along each front-side support member 22, the frictional force acting between each slide member 46 and each front-side support member 22, or each bar shape centering on the link member 40 is used. Due to the resistance generated in the link member 40 when the member 36 rotates with respect to each rod-shaped member 42, the mounting unit 30 (more precisely, the mounting unit 30 is mounted on the mounting unit 30) as shown in FIG. When the object is pushed to the back side by the operator, the placement unit 30 slowly rotates about the shaft 39. For this reason, when an operator inclines the mounting part 30, it becomes possible to prevent troubles such as the operator being injured. In other words, such a link mechanism 48 is not provided, and simply placing the rod-shaped member 38 of the mounting portion 30 with respect to the support portion 20 around the shaft 39 allows the mounting portion 30. (To be more precise, when the object placed on the placement unit 30) is pushed to the back by the operator, the placement unit 30 suddenly rotates around the shaft 39, There is a possibility that troubles such as the operator's hand being pinched between the constituent members of the work table 10 occur. Even when the placement unit 30 returns from the second position as shown in FIG. 2 to the first position as shown in FIG. 1, the placement unit 30 is provided with the link mechanism 48 so that the placement unit 30 is pivoted. 39, and therefore, it is possible to prevent the operator from being injured when returning the placement unit 30 to the first position as shown in FIG. Will be able to.

  A pair of left and right slide members 46 is attached with one bar-shaped weight 44 extending in the horizontal direction. By providing such a weight 44, even if an object is placed on the placement portion 30, the placement portion can be placed by the weight 44 if the operator does not apply force to the placement portion 30 or the object. Since a force that rotates 30 in the counterclockwise direction in FIGS. 1 and 2 is applied about the shaft 39, the mounting portion 30 is maintained in the first position as shown in FIG. Thus, the bottom member 32 of the mounting portion 30 is maintained in a state extending substantially along a horizontal plane.

  Further, in the present embodiment, the shaft 39 on which the rod-shaped member 38 of the placement unit 30 rotates with respect to the upper connection member 26 of the support unit 20 is the center of gravity of the object placed on the placement unit 30 (FIG. 1). 2 (indicated by a two-dot chain line) in FIG. 1 (ie, the left side in FIG. 1). For this reason, when an object is placed on the placement unit 30, the force by which the placement unit 30 rotates around the shaft 39 in the clockwise direction in FIG. 1 or FIG. Part 30 is added. Here, in the present embodiment, the placement unit 30 is pivoted by the weight 44 rather than the force of the placement unit 30 rotating around the shaft 39 in the clockwise direction in FIGS. 1 and 2 due to the weight of the object. The weight of the weight 44 is set in advance so that the force of rotating in the counterclockwise direction in FIGS. For this reason, only by placing the object on the placement unit 30, the placement unit 30 is maintained at the first position as shown in FIG. On the other hand, when the operator rotates the mounting portion 30 from the first position as shown in FIG. 1 to the back side around the shaft 39 and moves to the second position as shown in FIG. A part of the force that the mounting portion 30 rotates about the shaft 39 in the counterclockwise direction in FIGS. 1 and 2 is that the mounting portion 30 has the shaft 39 as the center in FIGS. Since the force is counterbalanced with the force rotating in the clockwise direction, the force with which the operator pushes the placement unit 30 when rotating the placement unit 30 can be reduced.

  Next, the operation | movement at the time of performing work, such as an operator sticking a label on objects, such as a container with which the liquid etc. were filled, using the worktable 10 which consists of such a structure is demonstrated.

  The operator places an object such as a container filled with a liquid or the like on the placement unit 30. At this time, as shown in FIG. 1, the bottom surface of the object is in contact with the bottom member 32 and the back side surface of the object is in contact with the back member 34. In addition, since the weight 44 is provided in the mounting part 30 as mentioned above, the mounting part 30 will be 1st as shown in FIG. 1 only by mounting a target object in the mounting part 30. Will be maintained in position. Thereafter, the operator pushes the placement unit 30 (more precisely, the object placed on the placement unit 30) to the back side to rotate the placement unit 30 about the shaft 39 to the back side. . More specifically, when the mounting portion 30 is pushed to the back side, each slide member 46 moves upward in the vertical direction along each front side support member 22, and each rod-like member 36 is centered on the link member 40. The rod-shaped member 42 rotates in the clockwise direction in FIG. At the same time, each rod-shaped member 38 rotates about the shaft 39 in the clockwise direction in FIG. Thereby, the mounting part 30 moves to the second position as shown in FIG. 2, and the bottom member 32 of the mounting part 30 is inclined with respect to the horizontal plane. In this case, as shown in FIG. 4, the worker looks down on the front of the object placed on the placement unit 30 obliquely downward, and the front of the object faces the worker. Thus, the operator can perform an operation such as attaching a label to an object without squatting.

  In addition, in FIG. 5, operation | movement when an operator performs the operation | work which sticks a label on target objects, such as a container, using the conventional work table 50 as a comparison object is shown roughly. In the conventional worktable 50 as shown in FIG. 5, since the height level of the mounting plate 52 is located at, for example, the height of the operator's knee, the container mounted on such a mounting plate 52 When performing an operation such as attaching a label to an object such as an object, it is necessary for the operator to squat down, and when such an operation is repeated, there is a problem that the burden on the operator increases. On the other hand, when the workbench 10 according to the present embodiment is used, as shown in FIG. 4, the worker rotates the mounting portion 30 on which the object such as the container is placed around the shaft 39. By simply making it, the operator is standing down on the front of the object placed on the placement unit 30 while standing, and the front of the object faces the worker in the standing state. Thus, the operator can incline backward with respect to the vertical direction, so that the operator can perform operations such as attaching a label to the object without squatting.

  Then, when the operator finishes the work such as attaching a label to an object such as a container placed on the placement unit 30, the worker takes out the object from the placement unit 30. In this case, due to the force by which the mounting portion 30 rotates about the shaft 39 in the counterclockwise direction in FIG. 1 or FIG. It will be returned to the 1 position. In this way, it is possible to continue to perform operations such as labeling the next object using the work table 10 according to the present embodiment. Further, when the placement unit 30 returns from the second position as shown in FIG. 2 to the first position as shown in FIG. 1, the placement unit is provided with the link mechanism 48 having the slide member 46 and the like. 30 rotates slowly about the shaft 39, so that troubles such as injury of the operator occur when the mounting portion 30 is returned to the first position as shown in FIG. This can be suppressed.

  According to the work table 10 of the present embodiment having the above-described configuration, the mounting unit 30 on which an object such as a container is mounted is rotatable by the support unit 20 around a shaft 39 extending in a substantially horizontal direction. When the object is not placed on the placement part 30, the bottom member 32 of the placement part 30 extends along a substantially horizontal plane, and the object is placed on the placement part 30. Since the bottom member 32 is inclined with respect to the horizontal plane when the mounting portion 30 is rotated with respect to the support portion 20 in a state where is placed, the operator has placed a target such as a container. It is possible to perform operations such as attaching a label to an object without squatting only by rotating the mounting portion 30 about the shaft 39, and thus the burden on the operator can be reduced. In addition, since the work table 10 according to the present embodiment does not use a driving source such as a cylinder or a linear motor, the manufacturing cost and running cost of the apparatus can be reduced.

  Moreover, in the worktable 10 of the present embodiment, as described above, the back member 34 is provided so as to extend upward from the edge on the back side of the bottom member 32, and the object is placed on the placement unit 30. When the mounting portion 30 is rotated with respect to the support portion 20 in the placed state, the bottom member 32 is inclined obliquely downward toward the back member 34. In this case, even if the bottom member 32 is inclined with respect to the horizontal plane as shown in FIG. 2, the object falls from the bottom member 32 to the back side by providing the back member 34. There is no.

  Further, in the work table 10 of the present embodiment, as described above, when the mounting unit 30 is rotated with respect to the support unit 20 in a state where the object is mounted on the mounting unit 30, the bottom member 32. Is inclined at an angle within a range of 30 to 60 degrees with respect to the horizontal plane. In this case, the worker is standing down on the front of the object placed on the placement unit 30 in a standing state, and the front of the object is opposed to the standing worker. So that it tilts backward at an angle in the range of 30 to 60 degrees with respect to the vertical direction, so that the operator can perform operations such as labeling an object without squatting. Become.

  Further, in the work table 10 of the present embodiment, as described above, when the object is not placed on the placement unit 30, the bottom member 32 of the placement unit 30 extends along a substantially horizontal plane. A weight 44 is provided to maintain the weight. In this case, when the object is simply placed on the placement unit 30, the placement unit 30 is maintained at the first position as shown in FIG. When the operator finishes the work such as attaching a label to an object such as a container placed on the placement unit 30 and removes the object from the placement unit 30, the placement unit 30 is moved by the weight 44. The mounting portion 30 is automatically returned to the first position as shown in FIG. 1 by the force rotating in the counterclockwise direction in FIGS. Work such as sticking a label on the object using the work table 10 can be continued.

  Moreover, in the workbench 10 of the present embodiment, as described above, the shaft 39 on which the mounting unit 30 rotates with respect to the support unit 20 is more than the center of gravity of the object mounted on the mounting unit 30. It is located on the near side. In this case, when the operator rotates the mounting portion 30 to the back side about the shaft 39, the mounting portion 30 is rotated counterclockwise in FIG. 1 or FIG. Part of the rotational force is offset by the force by which the mounting part 30 rotates about the shaft 39 in the clockwise direction in FIGS. 1 and 2 due to the weight of the object. It is possible to reduce the force with which the operator pushes the placement unit 30 when making it.

  Moreover, in the worktable 10 of this Embodiment, as above-mentioned, the support part 20 has the rod-shaped near side support member 22 extended in a perpendicular direction, and the mounting part 30 has a near side support member. A link mechanism 48 having a slide member 46 that slides relative to the support mechanism 22 is provided. Thus, it rotates around the shaft 39. When such a link mechanism 48 is provided, when the mounting portion 30 is rotated about the shaft 39, the mounting portion 30 rotates slowly about the shaft 39. It is possible to suppress the occurrence of troubles such as injury to the operator.

A support portion 120 that supports the mounting portion 130 so as to be rotatable about a shaft 139 that extends in the vertical direction, and a base portion 150 that supports the support portion 120 so as to be rotatable around a shaft 140 that extends in a substantially vertical direction. The caster 160 is provided. When the object is not placed on the placement unit 130, the placement unit 130 is maintained at the first position as shown in FIGS. 6 and 7, while the object is placed on the placement unit 130. When the mounting unit 130 is rotated with respect to the support unit 120 in the state of being placed, the mounting unit 130 moves to a second position as shown in FIG. 8 (that is, a position inclined by 90 ° with respect to the horizontal plane). It has become. Then, when performing an operation such as inspection of an object such as a container conveyed by the conveyance mechanism using such a work table 110, the worker first holds a first lever 141 and the like described later, and FIG. The mounting unit 130 on the work table 110 is directed toward the transport mechanism (that is, in the left direction in FIG. 6) so that the state shown in FIG. Thereafter, the container transported by the transport mechanism is moved from the transport mechanism to the placement unit 130 and placed on the placement unit 130. Then, the operator holds a second lever 142 and the like to be described later, and rotates the mounting portion 130 by 90 ° about the shaft 140 extending in the vertical direction (that is, the same state as that shown in FIG. 7). Thus, the placement unit 130 is directed toward the worker. Next, the operator grips a handle member 137 and the like which will be described later, and rotates the mounting portion 130 by 90 degrees about a shaft 139 extending in the horizontal direction, thereby causing the side surface of the object such as a container to move vertically. Work upwards, such as inspecting the appearance of the container and checking for leaks. That is, in FIG. 7, the paper surface side of the work table 110 is the front side for the operator, while the paper surface back side of the work table 110 is the back side for the worker. Details of each component of the work table 110 will be described below.

  As shown in FIG. 6, a plurality of casters 160 are provided at the lower end of the work table 110 (that is, the lower end of the base portion 150 (described later)). As a result, the entire work table 110 can be easily moved, and the work table 110 can be used in a state in which the work table 110 is close to the end of a transport mechanism such as a roller conveyor. Further, since the caster 160 is provided with a stopper, the work table 110 does not move even when an object such as a container is moved from the transport mechanism such as a roller conveyor to the work table 110. .

  The base portion 150 is composed of a plurality of pipes, and has a substantially square shape when viewed from the upper surface side (that is, the surface side seen from the upper side to the lower side in the state shown in FIG. 6). Is formed. Further, the base portion 150 is connected to the support portion 120 via a shaft 140 extending in the vertical direction, and the support portion 120 can be rotated about the shaft 140. In addition, as described above, since the mounting unit 130 is supported by the support unit 120, the mounting unit 130 is integrated with the support unit 120 by rotating the support unit 120 with respect to the base unit 150. It can be rotated about the shaft 140 with respect to the base portion 150.

  Even if the work table 110 is not provided with the shaft 140 and the support portion 120 cannot be rotated with respect to the base portion 150 about the shaft extending in the vertical direction, a work table, which will be described later. Work such as inspection of the appearance of an object such as a container filled with liquid or the like using 110 can be performed.

  Further, the work table 110 includes a pair of link members 144 as shown in FIGS. 9A to 9C as a lock mechanism for preventing the support 120 from rotating about the shaft 140 extending in the vertical direction. 146 (described later) is provided. For example, the orientation of the work table 110 can be locked in the state shown in FIG. As a result, when the object such as a container moved from the transport mechanism to the placement unit 130 hits a plurality of back rollers 134a (described later) provided on the placement unit 130, the support unit 120 is pivoted. It is possible to prevent the rocking about 140. In this way, work such as inspection of an object such as a container filled with liquid or the like performed using the work table 110 can be performed more safely.

  Each link member 144, 146 limits the rotation angle of the support portion 120 around the axis 140 extending in the vertical direction to an angle within a predetermined range. Note that the rotation angle of the support portion 120 with respect to the base portion 150 in the second embodiment is set to 0 ° in the state shown in FIG. 6 (that is, the work table 110 faces the transport mechanism). From the state shown in FIG. 6, the direction in which the work table 110 is rotated toward the worker side (that is, the direction in which the work table 110 is rotated so as to face the paper surface side in FIG. 6) is the positive rotation direction.

  More specifically, each link member 144, 146 extends from the state in which the mounting portion 130 shown in FIG. 6 extends in the horizontal direction so as to face the transport mechanism, so that the operator can move the first lever 141 (described later) or the like. The rotation angle of the support part 120 is limited so that the support part 120 does not rotate more than 90 ° with respect to the base part 150 when the support part 120 is rotated forward. ing. As a result, it is possible to prevent the operator from accidentally rotating the support portion 120 by 90 ° or more. The angle at which the support part 120 rotates with respect to the base part 150 may be limited to other ranges such as 0 ° to 135 ° or 0 ° to 180 °, for example. You may restrict | limit the rotation direction of the support part 120 so that it can rotate only to a reverse direction. Even in this case, as will be described later, the work table 110 can be used to perform work such as inspection of the appearance of an object such as a container filled with liquid or the like.

  Here, with reference to FIGS. 9A to 9C, a pair of lock mechanisms for preventing the support portion 120 from rotating with respect to the base portion 150 about the shaft 140 extending in the vertical direction. The configuration of the link members 144, 146, etc. will be described in detail. FIGS. 9A to 9C are schematic configuration diagrams showing a schematic configuration when the pair of link members 144, 146, etc. are viewed from above downward in the vertical direction. FIG. 9A is a diagram illustrating a state where the placement unit 130 of the work table 110 faces the transport mechanism (indicated by reference symbol C). FIG. 9B shows a state where the mounting unit 130 of the work table 110 is rotated from the state facing the transport mechanism to the state facing the operator (see FIG. 9C). It is a figure which shows the state of. FIG. 9C is a diagram showing a state (see FIG. 7) in which the placement unit 130 of the work table 110 faces the worker.

  As shown in FIG. 9A and the like, each of the pair of link members 144 and 146 is rotatable about two rod-shaped members and an axis extending in the substantially vertical direction at one end of the two rod-shaped members. Shaft members 144a and 146a for supporting the above. The other end of each rod-like member (that is, the end on the side not supported by the shaft members 144a and 146a) is connected to the base portion 150 and the support portion 120, respectively. For this reason, by deforming the link members 144 and 146 about the shaft members 144a and 146a, the support portion 120 can be rotated with respect to the base portion 150 about the shaft 140. .

  Further, the pair of link members 144 and 146 is a state in which the two rod-like members included in the link members 144 and 146 are folded in a predetermined direction when viewed from above (for example, the link member shown in FIG. 9A). 144) and a state (for example, a link member 144 shown in FIG. 9C) that is substantially linear when viewed from above, is configured to be deformable. The link members 144 and 146 that are substantially linear when viewed from above can be folded only in the predetermined direction, and can be folded in a direction opposite to the predetermined direction. I can't do it. For this reason, the two rod-like members included in the link member 144 are like a stick when they are deformed from the folded state shown in FIG. 9A to the substantially linear shape shown in FIG. 9C. It comes to work. As a result, the support portion 120 acts as a lock mechanism for preventing the support portion 120 from rotating with respect to the base portion 150 about the shaft 140. Similarly, when the link member 146 is deformed from the folded state shown in FIG. 9C so as to have a substantially linear shape shown in FIG. The portion 120 acts as a lock mechanism for preventing the portion 120 from rotating with respect to the base portion 150 about the shaft 140. In the present embodiment, the pair of link members 144 and 146 has the support portion 120 formed on the base portion 150 when the link members 144 and 146 are deformed from a folded state to a substantially linear shape. It is configured to be in a state rotated by 90 °.

  With the above-described configuration, the pair of link members 144 and 146 has a rotation angle of the support portion 120 with respect to the base portion 150 around the shaft 140 within a predetermined range (that is, 0 ° to 90 °). It has a role as a lock mechanism for limiting the angle to a certain angle. Further, this locking is performed when one of the link members 144 and 146 has a substantially linear shape.

  Further, the work table 110 is provided with a first lever 141 and a second lever 142 as means for releasing the lock for preventing the rotation of the support portion 120 around the shaft 140 by the lock mechanism. The first lever 141 and the second lever 142 can be operated with one hand. Thus, the operator can easily release the lock for preventing the rotation of the support portion 120 after placing an object such as a container on the placement portion 130. Further, the first lever 141 and the second lever 142 not only unlock the support 120 by the lock mechanism, but also the base 120 around the shaft 140 extending in the vertical direction. It has a role as a grip part (that is, a handle) for gripping when rotating the part 150.

  Here, as shown in FIG. 9A and the like, the first lever 141 is connected to a portion where one end portion of the link member 144 is connected to the support portion 120, and the work is started from the support portion 120. It is provided so as to protrude outside the table 110. The second lever 142 is connected to a portion where one end portion of the link member 146 is connected to the support portion 120, and is provided so as to protrude from the support portion 120 to the outside of the work table 110. . In addition, as described above, the other end of each link member 144, 146 is connected to the base portion 150. Accordingly, the operator can rotate the support portion 120 relative to the base portion 150 by rotating the first lever 141 or the second lever 142.

  More specifically, as described above, each of the link members 144 and 146 is configured to lock the rotation around the shaft 140 of the support portion 120 when one of the link members 144 and 146 has a substantially linear shape (for example, FIG. 9 (c)). And in the state (refer FIG.9 (c)) where rotation of the support part 120 is locked by the link member 144, an operator hold | grips the 1st lever 141 and this side (namely, downward direction in FIG. 9). The lock for preventing the rotation of the support portion 120 is released by pulling the support portion 120. That is, when the operator pulls the first lever 141 toward the front side (that is, the downward direction in FIG. 9), the link member 144 having a substantially linear shape has a predetermined direction centered on the shaft member 144a. The force that can be folded is applied. For this reason, the link member 144 is deformed so as to be folded from a substantially linear shape, and the lock for preventing the support portion 120 from rotating relative to the base portion 150 is released. Accordingly, the lock for preventing the rotation of the support portion 120 by the link member 144 can be released only by the operator pulling the first lever 141 toward the front side. That is, the first lever 141 has a role as a lock release lever.

  Furthermore, the operator can rotate the support portion 120 by 90 ° with respect to the base portion 150 by releasing the lock and pulling the first lever 141 to the near side while holding the first lever 141. When the support portion 120 is rotated by 90 ° with respect to the base portion 150 (that is, when the support portion 120 is rotated from the state shown in FIG. 9C to the state shown in FIG. 9A), the link member 144 is rotated. Instead, the link member 146 automatically locks the rotation of the support portion 120 relative to the base portion 150.

  In addition, the worker moves the second lever 142 on the work table 110 in a state where the rotation of the support part 120 with respect to the base part 150 is automatically locked by the link member 146 (see FIG. 9A). The lock for preventing the rotation of the support portion 120 relative to the base portion 150 is released by pushing the back portion 130 (that is, the right direction in FIGS. 9A to 9C). That is, when the operator pushes the second lever 142 in the right direction in FIGS. 9A to 9C, the link member 146 having a substantially linear shape is in a predetermined direction centered on the shaft member 146a. The force that can be folded is applied. For this reason, the link member 146 is deformed so as to be folded from the substantially linear shape, and the lock for preventing the support portion 120 from rotating relative to the base portion 150 is released. As a result, the operator can release the lock for preventing the support member 120 from rotating by the link member 146 simply by pressing the second lever 142 in the right direction in FIGS. It becomes like this. That is, the second lever 142 has a role as a lock release lever.

  Further, the operator can rotate the support portion 120 by 90 ° with respect to the base portion 150 by continuously pressing the second lever 142 in the right direction in FIGS. 9A to 9C after releasing the lock. It can be done. When the support portion 120 is rotated by 90 ° with respect to the base portion 150 (that is, when the support portion 120 is rotated from the state shown in FIG. 9A to the state shown in FIG. 9C), the link member 146 is provided. Instead, the rotation of the support part 120 relative to the base part 150 is automatically locked by the link member 144.

  The support portion 120 is formed of a plurality of pipes, and a support portion 122 for supporting the mounting portion 130 to be rotatable via a shaft 139 extending in the horizontal direction, and a substantially rectangular parallelepiped that supports the support portion 122. And a frame portion 124 having a shape. Thus, the operator can rotate the mounting portion 130 with respect to the support portion 120 around the shaft 139.

  In addition, the placement unit 130 includes a bottom member 132 that contacts the bottom surface of the placed object, a back member 134 that contacts the back surface of the placed object, and the placed object from the placement unit 130. It has a side member 136 for preventing it from falling, a handle member 137 for an operator to hold, and a weight 138. Further, the back member 134 is provided so as to extend upward from an end edge on the back side (that is, the right side in FIG. 6) of the bottom member 132. Further, the side members 136 are provided so as to extend upward from both the edges on the paper surface front side and paper surface back side in FIG. This prevents the object placed on the placement unit 130 from falling from the direction orthogonal to the paper surface in FIG. The operator can easily rotate the mounting portion 130 with respect to the support portion 120 about the shaft 139 by gripping the handle member 137.

  The shaft 139 is provided with a stopper (not shown) so as to limit the rotation angle of the mounting portion 130 around the horizontally extending shaft 139 to an angle within a predetermined range. . Note that the rotation angle of the mounting portion 130 with respect to the support portion 120 in the second embodiment is set to 0 ° in the state shown in FIG. 6 and is rotated in the clockwise direction from the state shown in FIG. The direction in which the person grips the handle member 137 and the like and lifts the handle member 137 is defined as the positive rotation direction.

  More specifically, the stopper moves the mounting unit 130 from the state where the mounting unit 130 shown in FIG. 6 extends in the horizontal direction so as to face the transport mechanism to the state shown in FIG. The rotation angle of the mounting portion 130 is limited so that the mounting portion 130 does not rotate 90 ° or more when rotated clockwise. As a result, it is possible to prevent an operator from accidentally rotating the placement unit 130 by 90 ° or more.

  Further, as shown in FIG. 6, the work table 110 according to the present embodiment has a state in which the bottom member 132 of the placement unit 130 extends along a substantially horizontal plane when no object is placed on the placement unit 130. It becomes. On the other hand, when the mounting unit 130 is rotated with respect to the support unit 120 about the shaft 139 in a state where the object is mounted on the mounting unit 130, the bottom member 132 is moved with respect to the horizontal plane as shown in FIG. Will be inclined. More specifically, when the mounting unit 130 is rotated with respect to the support unit 120 in a state where an object is mounted on the mounting unit 130, the bottom member 132 is inclined by 90 ° with respect to the horizontal plane (that is, The bottom member 132 extends vertically upward). As described above, since the back member 134 is provided so as to extend upward from the inner edge of the bottom member 132, the bottom member 132 is inclined by 90 ° with respect to the horizontal plane as shown in FIG. However, the object does not fall from the bottom member 132 to the back side. In addition, since the bottom member 32 can be inclined by 90 ° with respect to the horizontal plane, operations such as inspection of the appearance of an object such as a container filled with liquid or the like and inspection for the presence or absence of liquid leakage can be easily performed. Can be done.

  Further, as shown in FIG. 6, the operation is performed so that the height of the mounting surface of the bottom member 132 in the first position from the ground is substantially the same as the height of the conveying surface of the conveying mechanism such as a conveyor from the ground. A stand 110 is configured. Accordingly, an object such as a container transported by a transport mechanism such as a conveyor can be easily placed on the placement unit 130 of the work table 110 without squatting, so that it remains standing. Operations such as inspection of the outer surface of the container and inspection for the presence or absence of liquid leakage can be performed, and thus the burden on the operator can be reduced.

  As shown in FIG. 6, the bottom member 132 has a plurality of (for example, six) bottom rollers 132a, and each roller is rotatable about an axis extending in the horizontal direction. Further, these rollers can freely rotate in the clockwise direction and the counterclockwise direction with the direction orthogonal to the paper surface in FIG. 6 as the rotation axis. Furthermore, as described above, the height of the transport surface of the transport mechanism from the ground and the height of the mounting surface of the bottom member 132 from the ground are substantially the same. Accordingly, by sliding an object such as a container conveyed by the conveyance mechanism in the depth direction of the placement unit 130 (that is, in the right direction in FIG. 6), the container or the like is transferred from the conveyance mechanism to the placement unit 130. The object can be easily moved.

  Further, as described above, each bottom roller 132a can be rotated in the clockwise direction and the counterclockwise direction in FIG. 6, thereby receiving an object such as a container from the transport mechanism to the mounting portion 130. Each bottom roller 132a can be used not only when taking out an object such as a container from the placing portion 130 but also when taking out the object such as a container. The operator may lift the object such as a container placed on the placement unit 130 from the placement unit 130 by lifting (that is, without using the bottom roller 132a). .

  Further, as shown in FIG. 7, the back member 134 has a plurality of (for example, two) back rollers 134a, and each roller has a clockwise direction around an axis extending in the vertical direction in FIG. It can be rotated counterclockwise. Furthermore, as described above, the placement unit 130 can be rotated by 90 ° about the axis 139 extending in the horizontal direction. Accordingly, the placement unit 130 on which the object such as the container is placed is rotated by 90 ° from the first position shown in FIG. 6 or 7 to the second position shown in FIG. Can be rotated easily by the back roller 134a in a state where the back roller 134a is in contact with each back roller 134a, such as inspection of the outer surface of the object such as a container or inspection for the presence or absence of liquid leakage. Work can be performed more easily.

  In addition, each back roller 134a has a container when an object such as a container is placed on the placement unit 130 (that is, when an object such as a container is moved from the transport mechanism to the placement unit 130). It may be used as a positioning member for positioning an object such as. In this case, the placement unit 130 can be rotated in a state in which each back roller 134a and an object such as a container placed on the placement unit 130 are in contact with each other.

  As shown in FIG. 6, the length of the lateral member 136 in the left-right direction in FIG. 6 is the length of the object such as a container to be placed on the placement unit 130 in the same direction (that is, The mounting portion 130 is configured to be larger than the length in the left-right direction in FIG. As a result, when the placement unit 130 on which an object such as a container is placed is rotated 90 ° from the first position shown in FIG. 6 or 7 to the second position shown in FIG. A part of an object such as a container that is in contact with the roller 134 a protrudes upward from each side member 136. Therefore, the operator can more easily rotate the object such as a container that is in contact with each back roller 134a.

  In addition, on the lower surface side of the bottom member 132 (that is, the surface opposite to the side on which the object is placed on the placement portion 130), one bar shape extending in the horizontal direction (that is, the left-right direction in FIG. 7). A weight 138 is attached. By providing such a weight 138, even if an object is placed on the placement unit 130, if the operator does not apply a force to the placement unit 130 or the object, the placement unit 138 is placed by the weight 138. Since a force that rotates 130 in the counterclockwise direction in FIG. 1 about the shaft 139 is applied, the mounting portion 130 is maintained in the first position as shown in FIG. The bottom member 132 of the mounting part 130 is maintained in a state extending substantially along a horizontal plane.

  Further, in the present embodiment, the shaft 139 on which the placement unit 130 rotates with respect to the support portion 122 of the support unit 120 is positioned closer to the front side than the center of gravity of the object placed on the placement unit 130. It has become. Therefore, when an object is placed on the placement unit 130, a force that causes the placement unit 130 to rotate about the shaft 139 in the clockwise direction in FIG. 6 due to the weight of the object is applied to the placement unit 130. Be able to. Here, in the present embodiment, the mounting portion 130 is centered on the shaft 139 by the weight 138 rather than the force that causes the mounting portion 130 to rotate about the shaft 139 in the clockwise direction due to the weight of the object. The weight of the weight 138 is set in advance so that the force that rotates counterclockwise in FIG. 6 is increased. For this reason, only by placing the object on the placement unit 130, the placement unit 130 is maintained at the first position as shown in FIG. On the other hand, when the operator rotates the mounting portion 130 from the first position as shown in FIG. 6 to the back side around the shaft 139 and moves it to the second position as shown in FIG. Part of the force that causes the placement unit 130 to rotate in the counterclockwise direction in FIG. 6 about the axis 139 is rotated in the clockwise direction in FIG. 6 about the axis 139 by the weight of the object. Therefore, when the placement unit 130 is rotated, the force with which the operator pushes the placement unit 130 can be reduced.

  Next, with reference to FIGS. 6 to 9, the work table 110 having such a configuration is used to perform operations such as inspection of the appearance of an object such as a container filled with liquid or the like and inspection for the presence or absence of liquid leakage. The operation at the time of performing will be described.

  First, the operator holds the first lever 141 and applies a force to the first lever 141 so as to face the operator side (that is, the downward direction in FIGS. 9A to 9C). The front side (that is, the left side in FIG. 6) of the placement unit 130 on the work table 110 is directed toward the transport mechanism. At this time, the two rod-shaped members included in the link member 146 are substantially linear, so that the rotation of the support portion 120 is locked (see FIG. 9A). As a result, the mounting portion 130 is prevented from swinging about the shaft 140 extending in the vertical direction, and an object such as a container can be safely placed on the mounting portion 130. Next, the operator places an object such as a container on the placement unit 130 by sliding an object such as a container conveyed by a conveyance mechanism such as a roller conveyor toward the work table 110. As described above, the height of the mounting surface of the bottom member 132 provided in the mounting portion 130 from the ground is substantially the same as the height of the transport surface of the transport mechanism from the ground, and the bottom member Since the plurality of bottom roller 132 a is provided at 132, the operator can easily place the object on the bottom member 132. At this time, the object can be easily positioned by using each of the back rollers 134a. Further, as described above, since the mounting portion 130 is provided with the weight 138, the mounting portion 130 is not the first as shown in FIG. 6 simply by mounting the object on the mounting portion 130. Will be maintained in position.

  Next, the operator releases the lock by the link member 146 by holding the second lever 142 and applying a force to the second lever 142 so as to face the right direction in FIGS. To do. As a result, the support portion 120 can rotate with respect to the base portion 150 about the shaft 140. Thereafter, the operator further moves the second lever 142 in the right direction in FIGS. 9A to 9C to rotate the support portion 120 by 90 ° with respect to the base portion 150, so that the object such as a container is moved. The placement unit 130 placed is directed to the worker side (see FIG. 7). At this time, the two rod-shaped members included in the link member 144 have a substantially linear shape, whereby the rotation of the support portion 120 is locked (see FIG. 9C). Moreover, since the mounting part 130 is supported by the support part 120 as mentioned above, when the support part 120 is rotated, the mounting part 130 is also rotated together with the support part 120 and is directed toward the operator. .

  Then, the operator holds the handle member 137 provided on the mounting portion 130 with one hand, and holds the vicinity of the end portion on the front side (that is, the left side in FIG. 6) of the mounting portion 130 with the other hand. To do. After that, the handle member 137 and the end portion of the mounting portion 130 are lifted, and the mounting portion 130 is rotated by 90 ° with respect to the support portion 120 around the shaft 139 extending in the horizontal direction (that is, as shown in FIG. 8). Rotate to the second position). At this time, the mounting portion 130 is prevented from rotating by 90 ° or more with respect to the support portion 120 by the stopper described above. As a result, an object such as a container placed on the plurality of bottom rollers 132a provided on the bottom member 132 of the placement unit 130 is placed on each back roller 134a. (See FIG. 8).

  Next, in a state where an object such as a container is placed on each back roller 134a, the operator manually rotates the object such as a container using the back roller 134a while Work such as inspection and inspection for leakage. Then, after the work such as the inspection is finished, the mounting unit 130 is rotated in the reverse direction, and the mounting unit 130 is returned to the first position (that is, returned to the state shown in FIG. 7). The inspection work for an object such as a container filled with the liquid or the like used is completed.

  When performing work such as inspection of the appearance of an object such as a container using the work table 110 and inspection for the presence or absence of liquid leakage, the front side of the mounting unit 130 on the work table 110 is first directed toward the transport mechanism. Then, after placing the object on the placement unit 130, the placement unit 130 is rotated by 90 ° about the axis 139 extending in the horizontal direction (that is, rotated to the second position shown in FIG. 8). The outer surface or the like of the container may be inspected, and then the second lever 142 or the like may be used to rotate the mounting unit 130 relative to the support unit 120 so as to face the operator.

  In FIG. 10, as an object to be compared, an operation when an operator performs an operation such as an inspection of the appearance of an object such as a container or the presence or absence of liquid leakage using a conventional work table 170 is schematically illustrated. Show. In the conventional work table 170 as shown in FIG. 10, even if the height of the mounting surface from the ground and the height of the transport surface of the transport mechanism such as a conveyor from the ground are substantially the same, Since the plurality of bottom rollers 132a are not provided unlike the work table 110, the operator needs to lift the object such as a container once and place it on the mounting plate 172. In addition, when performing an operation such as an inspection for the presence or absence of liquid leakage of an object such as a container filled with a liquid or the like, an operator needs to grip and tilt a part of the container itself. Such an operation has a problem that the burden on the operator becomes particularly large in the case of a heavy object such as a container filled with a liquid or the like. Further, when inspecting the appearance of an object such as a container placed on such a placement plate 172, an operator needs to squat to see the side of the object such as a container from the front, for example. When such work is repeated, there is a problem that the burden on the worker increases. In addition, when inspecting the back side of an object such as a container, it is necessary to go around the back side of the container, and there is a problem that work is troublesome. On the other hand, when the work table 110 according to the present embodiment is used, as shown in FIG. 8, the worker rotates the mounting portion 130 on which an object such as a container is mounted around the shaft 139. The operator can look down on the front of the object placed on the placement unit 130 while standing, so that the worker can inspect the appearance of the object such as a container without squatting. It is possible to perform work such as inspection for the presence or absence of liquid leakage.

  According to work table 110 of the present embodiment configured as described above, mounting unit 130 on which an object such as a container is mounted is rotatable by support unit 120 about shaft 139 extending in a substantially horizontal direction. When the object is not placed on the placement unit 130, the bottom member 132 of the placement unit 130 extends along a substantially horizontal plane, and the object is placed on the placement unit 130. Since the bottom member 132 is inclined with respect to the horizontal plane when the mounting unit 130 is rotated with respect to the support unit 120 in a state in which the object is mounted, the operator has placed a target such as a container. By rotating the mounting portion 130 about the shaft 139, it becomes possible to perform operations such as inspection of the appearance of the object and inspection for the presence or absence of liquid leakage without squatting, thereby reducing the burden on the operator. be able toIn addition, since the work table 110 according to the present embodiment does not use a drive source such as a cylinder or a linear motor, the manufacturing cost and running cost of the apparatus can be reduced.

  In addition, the work table 10 and the work table 110 according to each embodiment are not limited to the above-described aspects, and various changes can be made.

  For example, in the mounting unit 30 of the work table 10 according to the first embodiment, the bottom member 32 may include a rotating member that rotates the object mounted on the mounting unit 30.
