An opening formed in the screen, which moves along the first section screen by a manual operation of the operator, a second opening through which an article carrying device for carrying articles into the article placement space enters. The present invention also relates to an article processing facility provided with a first opening / closing portion that is switchable between a first open position that opens the first opening and a first closed position that closes the first opening.

  As an example of such an article processing facility, for example, in Japanese Patent Laid-Open No. 8-11312 (Patent Document 1), an article support body that supports a pallet that holds a plurality of loads is provided in an article arrangement space, and an operator Is configured to perform a picking operation to take out a necessary number of loads from a pallet located in the article placement space.

  In the article processing facility of Patent Document 1, a picking work space in which an operator performs picking work is provided on the front side of the article placement space, and a travel route on which a stacker crane as an article carry-in device travels is set on the rear side of the article placement space.

Japanese Patent Laid-Open No. 8-11312

  In Patent Document 1, it is not specified how the operator opens and closes the first opening / closing part, but according to the drawing of Patent Document 1, in the width direction of the pipe shutter included in the pipe shutter. It is considered that a plurality of pipe members along the line are held and opened / closed. However, with such a configuration, there is a possibility that stress concentrates on the grip portion of the pipe member and the pipe member is deformed. For this reason, when the operator opens and closes the first opening / closing portion, it is conceivable that the slat portion provided at the end portion in the width direction is grasped as a strong portion in the pipe shutter. However, since the slat portion of the pipe shutter is located at the end in the width direction, it is difficult for an operator facing the article placement space to grip and the workability is poor. Thus, it is conceivable to attach a gripping part that can be gripped by the operator to the first opening / closing part. However, depending on the position where the gripping part is attached, the gripping part may interfere with loading and unloading in picking work.

  Therefore, there is a demand for an article processing facility that is unlikely to be an obstacle for an operator who performs processing on an article in the article arrangement space, and that has good workability for the operator to close the first opening / closing section.

An article processing facility according to the present invention includes a partition body that partitions an article placement space in which articles are placed and includes a plurality of section screens, and an opening formed in a first section screen among the plurality of section screens. A first opening for an operator to enter the article arrangement space from outside the article arrangement space for processing the article in the article arrangement space, and the division screen different from the first division screen An opening formed in a certain second section screen, a second opening through which an article carrying device for carrying articles into the article placement space enters, and the first section screen by manual operation of the operator A first opening / closing portion that can be switched between a first open position that opens the first opening and a first closed position that closes the first opening, and movement of the first opening / closing portion. A guide rail for guiding ,
The guide rail is provided on the first section screen and extends in the up-down direction, and a curve that curves and extends from the upper end of the first rail portion toward the article arrangement space. A part, and
The first opening / closing part includes a first gripping part gripped by the operator,
The first gripping portion includes a first portion projecting toward the outside from the first opening portion, in a state where the first opening and closing part and a first closed position, downward from the projecting end of the first portion A second part that extends, and a third part that is provided at the lower end of the second part and is gripped by the operator ,
In a state where the first gripping portion is in a region corresponding to the first rail portion of the guide rail, the third portion of the first gripping portion is an end on the first closed position side of the first opening / closing portion. Located below the part,
In a state where the first closing portion before SL is in the first open position, in the region where the first gripper corresponds to the curved portion of said guide rail, said third portion of said first gripping section, said and not less than the same height as the said first closed position side of the end portion of the first opening and closing part in the direction of movement of the first closing part, characterized in that located at the upper end lower than the height level of the goods-layout space.

  That is, since the first gripping part is formed so as to protrude from the first opening / closing part to the outside, it is easy for an operator working outside the article placement space to grip the first gripping part. Then, in a state where the first opening / closing portion is in the first open position, the first gripping portion has a lower end that is the same as the end of the first opening / closing portion on the first closing position side in the moving direction of the first opening / closing portion. Since it is higher than the height, it is difficult to disturb the article processing operation (for example, picking operation) by the operator. Moreover, since the lower end of the first gripping portion is located at a position lower than the upper end height of the article placement space in a state where the first opening / closing portion is in the first open position, the operator opens the first opening / closing portion in the first open position. When the first grip portion is to be gripped to switch from the first position to the first closed position, the first grip portion can be easily gripped, and the first grip portion can be moved downward while gripping the first grip portion. Since the first opening / closing part can be closed, the first opening / closing part can be favorably closed.

  Therefore, it is possible to provide an article processing facility that is not disturbed by an operator who performs processing on an article in the article arrangement space, and that has good workability in the closing operation of the first opening / closing section by the operator.

  In the article processing facility according to the present invention, the first opening / closing portion includes a second gripping portion that is gripped by the operator separately from the first gripping portion, and the second gripping portion is the first opening / closing portion. In a state where the part is in the first closed position, it is preferable that the part is provided at a position above the first gripping part and lower than the upper end height of the article placement space.

  The first gripper is configured to move the first opening / closing part in the moving direction of the first opening / closing part so that the operator can easily grip the first opening / closing part when switching from the first opening position to the first closing position. It is preferable to provide at a position close to the position side end. However, with such a configuration, the first gripping portion is positioned at a low position where it is difficult for the operator to grip in the state where the first opening / closing portion is in the first closed position. According to this characteristic configuration, by providing the second grip portion at a position above the first grip portion and lower than the upper end height of the article placement space, the operator closes the first opening / closing portion from the first open position to the first close position. When switching to the position, the first opening / closing part can be closed by holding the second holding part instead of the first holding part at the position where it is difficult to hold or simultaneously with the first holding part, thereby improving workability. be able to.

  In the article processing facility according to the present invention, a second opening position for opening the second opening and a second opening for closing the second opening are moved along the second section screen by the operator's manual operation. A second opening / closing portion whose position can be switched between two closed positions is provided, and when the first opening / closing portion is the first opening position, the second opening / closing portion becomes the second closing position, and the first opening / closing portion It is preferable that an interlocking mechanism for interlocking the first opening / closing portion and the second opening / closing portion is provided so that the second opening / closing portion becomes the second opening position when the first opening position is set to the first closing position. .

That is, when the first opening / closing part is set to the first open position so as to perform the processing operation on the article located in the article arrangement space by the operator, the second opening / closing part opens the second opening for the article carrying-in device to enter. It becomes the 2nd closed position which closes. For this reason, while the worker is performing a processing operation on an article located in the article arrangement space, the article carry-in device is restricted from entering the article arrangement space.
Further, when an article is carried into the article placement space, the second opening / closing portion is set to the second open position so as to open the second opening for the article carrying-in device to enter. Since the 1 opening / closing part is in the first closed position, the operator can be prevented from entering the article placement space.
For this reason, the situation where an operator and an article carrying-in apparatus interfere in an article arrangement space can be avoided.

  In the article processing facility according to the present invention, the second opening / closing part is configured by arranging a plurality of long members at intervals in the moving direction of the second opening / closing part, and the second opening / closing part includes a pair of adjacent ones. It is preferable that a net-like body arranged along a surface defined by the long member is further provided, and a mesh interval in the net-like body is smaller than an interval between the adjacent long members.

That is, in order to reduce the weight of the first opening / closing part and the second opening / closing part (hereinafter simply referred to as the opening / closing part when collectively referred to), the opening / closing part is separated by a plurality of intervals in the moving direction of the opening / closing part. It is conceivable to use a so-called pipe shutter composed of long members arranged side by side.
At this time, the space outside the second opening / closing portion as viewed from the article placement space is a space in which the article loading device for carrying the article into the article placement space may be located. If an operator causes a part of the body to protrude outward from the gap between the long members constituting the second opening / closing part, the part of the operator's body may interfere with the article carrying device. There is.
According to this characteristic configuration, when the second opening / closing part is set to the second closed position, the net-like body is located between the article placement space and the outside, so that interference between the worker and the article carry-in device is prevented. be able to.

When the first opening / closing part S1 is in the first open position, the second opening / closing part S2 is in the second closed position, and the first opening / closing part S1 is in the first position. An interlocking mechanism for interlocking the first opening / closing part and the second opening / closing part is provided so that the second opening / closing part S2 is in the second open position when the closed position is set.

  As shown in FIG. 5, the shutter S is in a state in which long members U (metal pipes or the like) in a posture along the longitudinal direction of the traveling rail R are separated in a direction perpendicular to the longitudinal direction and adjacent to each other. It is configured by being connected by link members L that are discretely arranged in the longitudinal direction in a state in which the relative positional relationship in the circumferential direction between the elongated members U with the longitudinal direction of the scale member U as an axis is changeable. Yes. In the present embodiment, the link member L is formed of an aluminum plate-like body, and is provided at four locations separated in the longitudinal direction. At both ends in the longitudinal direction of each long member U, guide wheels that are fitted in the guide grooves of the guide rail G and are freely rotatable are attached. The shutter S can be moved along the guide rail G with a small force by reducing the frictional force with the guide rail G as much as possible by rolling the guide wheel. In the present embodiment, the moving direction of the shutter S is set along the guide rail G.

  In the moving direction of the shutter S, the longitudinal direction is along the longitudinal direction of the long member U and the plate thickness direction is adjacent to the end of the shutter S on the first rail portion G1 side (first closed position side). A stainless steel plate-like body W1 orthogonal to each of the arrangement direction of the long members U and the longitudinal direction is attached. Moreover, the 1st holding part T1 hold | gripped by the operator Y located in the picking work space E1 is attached to the longitudinal direction center part of the plate-shaped body W1.

  As shown in FIG. 5, when the shutter S is in the closed position, the first gripping portion T1 includes a pair of first portions T1A that protrude from the plate-like body W1 toward the picking work space E1, and the first portion T1A. A pair of second portions T1B that are bent from the projecting ends and extend downward, and a third member T1C that connects the lower ends of the pair of second portions T1B and extends along the longitudinal direction of the long member U are provided. ing. That is, the first grip portion T1 is formed so as to protrude outward from the first opening / closing portion S1. When the shutter S is in the closed position, the third member T1C is located at a position lower than the lower end of the plate-like body W1.

The plate-like body W1 is an article as the plate-like body W1 is guided by the curved portion between the first rail portion G1 and the second rail portion G2 when the shutter S is in the open position, and approaches the upper end side. It will be in the state which inclines in the form which approaches the arrangement | positioning space E2 side. For this reason, in the state where the shutter S is switched to the open position, the lower end of the third member T1C is the lower end of the plate-like body W1 in the moving direction of the shutter S (that is, the end portion on the closed position side of the shutter S). And almost the same height. Note that the third member T1C may be positioned higher than the lower end of the plate-like body W1 as long as it is difficult for the operator Y to grip, but at this time, the third member T1C is higher than the upper end height of the article arrangement space E2. Try to be in a low position.
That is, the first gripping portion T1 is the same as the end portion of the first opening / closing portion S1 on the first closing position side in the moving direction of the first opening / closing portion S1 in a state where the first opening / closing portion S1 is in the first opening position. It is provided so that its lower end is located at a position that is higher than the height and lower than the upper end height of the article arrangement space E2.

In the state where the shutter S is switched to the open position, the longitudinal direction is along the longitudinal direction of the long member U at a position above the plate-like body W1 and lower than the upper end height of the article arrangement space E2. A plate-like body W2 made of stainless steel that is orthogonal to the arrangement direction of the long members U whose thickness directions are adjacent to each other and the longitudinal direction is attached. In addition, a second gripping portion T2 that can be gripped by the worker Y located in the picking work space E1 is attached to a central portion in the longitudinal direction of the plate-like body W2.
That is, the first opening / closing part S1 includes a second gripping part T2 gripped by the operator Y separately from the first gripping part T1, and the second gripping part T2 has the first opening / closing part S1 in the first closed position. In a certain state, it is provided above the first gripping portion T1 and at a position lower than the upper end height of the article placement space E2.

  When the loading of the pallet P by the stacker crane 10 is completed, the worker Y starts the picking operation by switching the shutter S from the closed position to the open position. At this time, if only the first gripping portion T1 is provided on the shutter S, the operator Y must bend to grip the first gripping portion T1, as indicated by a two-dot chain line in FIG. The presence of the second gripping portion T2 allows the operator Y to grip the second gripping portion T2 and open the shutter S without bending, as indicated by the solid line in FIG.

  For example, when there is no load N on the pallet P, it is necessary to remove the empty pallet P by the stacker crane 10 and carry a new pallet P holding the load N into the article support D. . At this time, the operator Y switches the shutter S from the open position to the closed position. Thereby, the 2nd opening K2 side is open | released and it will be in the state which can carry in the goods support part D of the pallet P by the stacker crane 10. FIG. As shown in the dashed line circle in FIG. 5, the shutter S is provided with a detected portion F that moves integrally with the shutter S, and the shutter S is closed to the second rail portion G2 of the guide rail G. A detector 52K that detects the detected part F when the position is set (that is, when the second opening / closing part of the shutter S is set to the second closed position) is attached. And while the control device detects that the second opening / closing part of the shutter S is in the second closed position by the detector 52K, the stacker crane 10 carries the pallet P into the article support part D. The operation of the stacker crane 10 is controlled so as not to be performed.

  A case where the shutter S is switched from the open position to the closed position will be described. As shown in FIG. 10, when the shutter S is in the open position, as indicated by a dashed line Q in FIG. 10, the third member T1C at the lower end of the first gripping portion T1 is substantially the same height as the lower end of the plate-like body W1. It becomes. For this reason, the operator Y can easily hold the third member T1C in an upright posture, and at the same time, the third member T1C does not interfere with the loading / unloading operation of the load N when performing the picking operation. It is possible to suppress a decrease in workability.

  Further, a portion (second opening / closing portion S2) that closes the second opening K2 in the shutter S is defined by a pair of adjacent long members U, as shown in FIG. 5, FIG. 8, and FIG. A mesh body M arranged along the surface is attached. The mesh body M is formed by knitting resin yarns in a mesh pattern, and the mesh interval is smaller than the interval between adjacent long members U. It is preferable that the mesh | interval of the mesh body M is 1/2 or less of the space | interval of adjacent long members U. Furthermore, in order to prevent the operator's finger from passing by mistake, it is more preferable that the distance is about 1 cm.
