Description

The present invention relates to cabinet and drawer locking mechanisms.

A cabinet in which a plurality of drawers are arranged in vertical columns to store the plurality of drawers in a freely openable/closable manner may topple over if the plurality of drawers are opened at the same time. In particular, when a heavy object is stored in a cabinet, opening a plurality of drawers shifts the center of gravity of the cabinet, making it easy for the cabinet to topple over. Therefore, a cabinet has been proposed in which the other drawers cannot be opened once one of the drawers is opened (see, for example, Patent Documents 1 and 2).

Patent Literature 1 discloses a cabinet having a safety device (drawer lock mechanism) that prevents multiple drawers from being opened at the same time. This cabinet has a lock pin projecting from the outer surface of the side wall of each drawer, and a vertically movable lock bar inside the cabinet body. The lock bar is formed with a slit that is inclined in the width direction corresponding to each drawer. When all the drawers are housed inside the cabinet body, each lock pin is in a position where it can enter the gap. When one drawer is opened, the locking pin penetrates the slit and uses the slope of the slit to raise (or lower) the locking bar. Then, other drawers cannot be opened because the lock pin cannot enter the cut because the position of the cut is displaced with respect to the lock pin.

Further, Patent Literature 2 discloses a cabinet having an interlock assembly (corresponding to a drawer locking mechanism). This cabinet has a fixed member (corresponding to a fixed rail) fixed to the cabinet body and an expandable member (corresponding to a slider) attached to each drawer and movable together with the drawer. A pair of upper and lower slide plates are fitted to the front end of the fixing member so as to be movable upward or downward. The upper slide plate and the lower slide plate placed thereon are connected by a rod. An actuating member having vertically inclined surfaces is fixed to the distal end of the expandable member. When one drawer is opened, the inclined surface moves to move the pair of upper and lower slide plates upward or downward, so that the movement of the expandable member is not hindered. When one drawer is opened, the inclined surface of the actuating member pushes up the upper slide plate, which in turn pushes up the lower slide plate located above it. The drawer cannot be opened because the lower slide plate blocks the movement of the upper expandable member. Also, the lower slide plate at the bottom of the opened drawer prevents the upper slide plate at the lower level from moving upward. That is, the drawers arranged in the upper and lower stages of the opened drawer cannot be opened because the movement of the expandable member (operating member) is blocked by the slide plate.

JP 2014-39707 A JP-A-10-57168

The cabinet disclosed in Patent Literature 1 has a structure in which the lock pin moves the lock bar upward or downward so that when one of the drawers is opened, the other drawers cannot be opened. With this cabinet, any one drawer can be opened when all the drawers are housed in the cabinet body. However, it is not possible to lock all the drawers at the same time, and the drawers may open due to vibration or shaking. In addition, the lock pin moves the lock bar while sliding on the gap of the lock bar formed by bending the metal plate, and the friction load is large because the contact area between the lock pin and the sliding surface of the lock bar is small. , there is a problem in durability.

In the cabinet described in Patent Document 2, the upper and lower slide plates are moved up and down by the movement of the slanted surface of the operating member, so that when one drawer is opened, the other drawers cannot be opened. Since the angle of the inclined surface is 45 degrees with respect to the movement direction of the expansion and contraction member, the frictional load increases when the slide plate is moved up and down. However, there is a problem that it is not possible to obtain sexuality.

Further, each slide plate has its leading end fitted into an opening provided near the leading end of the fixing member so as to be vertically movable. The upper slide plate and the upper lower slide plate are connected by a rod, and the upper lower slide plate is fitted into the opening of the upper fixed member. In such a configuration, when the extensible member is moved, it bends between the opposed slide plates and the straightness of the pair of upper and lower slide plates is lost, which may hinder the vertical movement of each slide plate. That is, a drawer that should be locked may be opened, or a drawer that should be opened may be locked. In particular, when the number of drawers is more than three, the number of bends between the slide plates of each stage increases, and the loss of straightness tends to have a large effect.

In addition, in the cabinet of Patent Document 2, in order to lock all the drawers, an all-stage lock member is arranged at the uppermost or middle stage of a plurality of slide plates, and the slide plate on the lower side of the all-stage lock member has its own weight. It is configured to drop with However, if the straightness between the slide plates is lost, the slide plates may not drop and all the drawers may not be locked. In the following description, "to lock the drawer" means to prevent the drawer from opening, in other words, to lock the drawer while it is housed inside the cabinet.

In addition, the cabinet of Patent Document 2 has a structure in which the pair of upper and lower slide plates move up and down following the movement of the inclined surface of the operating member. Since the contact surface between the operating member and the slide plate has a mutual inclination angle of 45 degrees, even if the drawer is slightly opened or closed, the slide plate sensitively moves up and down with the same stroke as the drawer, so it is desirable to lock it. It is conceivable that the drawer is opened or that the drawer to be opened is locked.

Therefore, the present invention has been made to solve at least one of these problems, and it is possible to open a drawer that is desired to be opened and to prevent the opening of drawers in stages other than the opened drawer. It is intended to realize a locking mechanism for a cabinet and a drawer that is capable of achieving excellent durability.

The lock mechanism 25 for the cabinet 1 and the drawer 11 of the present invention will be described below with reference to FIGS. 1 to 10. FIG. In addition, the figures described below are schematic diagrams in which a part of the shape is simplified.

(First embodiment)
FIG. 1 is a perspective view showing the overall configuration of a cabinet 1 according to the first embodiment. The cabinet 1 is composed of a cabinet body 10 having a frame structure and a plurality of drawers 11 accommodated inside the cabinet body 10 . In the example of the cabinet 1 shown in FIG. 1, the cabinet body 10 is vertically divided into five spaces, each of which houses a drawer 11. These spaces are called drawers 11A, 11B, 11C, 11D, and 11E from the top. FIG. 1 illustrates a state in which the upper drawer 11A is opened and the lower drawers 11B to 11E are closed. In the following description, the drawer 11 may be used when the drawers 11A to 11E can be described in common without specifying them. In the cabinet 1, the configuration of the drawers 11 is not limited to the 5-tier configuration, and may be increased or decreased, for example, a 2-tier configuration, a 3-tier configuration, or a 6-tier configuration. In the following description, the direction in which each drawer is opened (pull-out side) is the front side, the opposite side is the back side, the right side as seen from the front side is the right side, and the left side is the left side.

Four wheels 12 are fixed to the lower part of the cabinet body 10 so that the cabinet 1 can be transported. At the bottom of the cabinet body 10, outriggers 13 are deployed in four directions. The outriggers 13 can be vertically extended and contracted, and can horizontally fix the cabinet 1 so as not to cause displacement with respect to the floor surface. The cabinet 1 shown in FIG. 1 is a so-called cabinet trolley that has wheels 12 and can be transported, but it can also be a fixed cabinet without wheels 12 and outriggers 13 . Although not shown, the cabinet body 10 is provided with side covers on both left and right sides, a back cover on the back side, and a top cover on the top. The side cover, rear cover, and top cover are made of transparent plates so that articles placed in the drawer 11 can be viewed from the outside. However, any one or all of the side cover, rear cover and top cover can be omitted.

The cabinet body 10 has a frame structure, and includes four vertical frames 14A, 14B, 14C, 14D extending in a direction perpendicular to the floor surface, a horizontal frame 15A connecting the vertical frames 14A and 14B, and a vertical frame. It has a horizontal frame 15B that connects 14C and the vertical frame 14D. The vertical frames 14A to 14D are fixed at the top by an upper frame 16 having four sides. The horizontal frames 15A, 15B and the upper frame 16 of each stage are fixed to each vertical frame by fasteners at intersections with each vertical frame. In the example shown in FIG. 1, the horizontal frames 15A and 15B are used in common for each stage of the drawer 11, and the vertical intervals of each stage are the same.

Since the drawers 11A to 11D have the same structure, the drawer 11A will be described as a representative example. The drawer 11A is arranged on a frame 17 having four sides, a table base 18 fixed to the upper surface of the frame 17, and an upper surface of the table base 18, and an article (for example, a work) is placed thereon. It is configured by a table (not shown). The table is positioned by guide pins 19 erected on a table base 18 . The table is made of a plate material having a shape corresponding to the article to be placed and a rigidity to the extent that it does not bend when the article is placed. A handle 20 is fixed to the front side of the frame 17 for opening and closing the drawer 11A. Carrying handles 21 for carrying the cabinet 1 are fixed to the vertical frames 14A to 14D, respectively, projecting in the left-right direction. Each drawer can be slid and opened/closed by slide rails 22 and 23 between the left horizontal frame 15A and the right horizontal frame 15B. The slide rails 22 and 23 are provided corresponding to the drawers 11A to 11E, respectively. The configuration of the slide rails 22 and 23 will be described with reference to FIGS. 2 and 3. FIG.

The left front vertical frame 14A has a slide plate 30A arranged above the drawer 11A, a slide plate 30B arranged between the drawer 11A and the drawer 11B, and a slide plate arranged between the drawer 11B and the drawer 11C. 30C, a slide plate 30D arranged between the drawer 11C and the drawer 11D, and a slide plate 30E arranged between the drawer 11D and the drawer 11E are mounted so as to be slidable in the vertical direction. . See FIG. 7 for the arrangement of the slide plates 30A to 30E. A lock that switches between a state in which any one of the drawers 11A, 11B, 11C, 11D, and 11E can be opened and a state in which the drawers 11 other than the opened drawer are closed by the slide rails 22, 23 and the slide plates 30A to 30E. A mechanism 25 is constructed (see FIG. 7). A stopper member 65 is arranged below the slide plate 30E to regulate the lowered position of the slide plates 30A to 30E. Above the uppermost slide plate 30A, an all-stage lock mechanism 31 for locking and unlocking the vertical movement of all the slide plates 30A to 30E is arranged. The full-stage lock mechanism 31 is fixed to the vertical frame 14A. The configuration of the all-stage lock mechanism 31 will be described with reference to FIG.

The cabinet 1 is a cabinet cart for transporting a work as an article, and when the article placed on the table is transported by a manipulator (not shown) of a robot device, the cabinet 1 and the table It is required to manage the relative position with the manipulator. For this purpose, the cabinet 1 is provided with marks for detecting respective positions on the cabinet body 10 and each table at positions facing the visual sensors (for example, CCD cameras, etc.) of the manipulator. The first target mark 32 and the second target mark 33 are arranged on the cabinet main body 10 and each drawer, respectively, and are marks for detecting the respective positions of the cabinet main body 10 and the table with a visual sensor. As shown in FIG. 1, a first target mark 32 is provided on the upper front side of the cabinet body 10 . A second target mark 33 is provided on the upper surface of the front side of the table (the table is not shown in FIG. 1, so the table base 18 is indicated by a dotted line). A second target mark 33 is arranged on each table of the drawers 11A to 11E.

The first target mark 32 makes it possible to detect the distance and inclination of the manipulator of the cabinet body 10 from the reference point. For example, as shown in FIG. 1, by detecting the second target mark 33 with the visual sensor when the drawer 11A is opened, it is possible to detect the relative position including the tilt of the drawer 11A with respect to the manipulator when the drawer 11A is opened. It becomes possible. That is, the manipulator can reliably grip and transport the workpiece placed on the table. In the drawers 11B to 11E, it is possible to similarly detect the relative position including the tilt of the table with respect to the manipulator. By using a mark having an identification function as the first target mark 32, it is possible to detect whether the cabinet 1 is to be transported. Also, the second target mark 33 can distinguish the table of each stage by using a mark having an identification function.

The all-stage lock mechanism 31 is fixed to the vertical frame 14A so as to overlap with the side of the slide plate 30A and not to hinder the movement of the slide plate 30A.

The lock lever 70 is pivotally supported by a shaft member 75 that is a first rotating shaft and fixed to the lock lever mounting plate 71 . The pressing member 72 is fixed to a pressing shaft lever 77, and the pressing shaft lever 77 is supported on the lock lever mounting plate 71 by a shaft member 78, which is a second rotating shaft. The presser shaft lever 77 and the lock lever 70 are connected by a link lever 79 , and the rotation of the lock lever 70 is transmitted to the presser member 72 via the link lever 79 and the presser shaft lever 77 . One end of the link lever 79 is supported by a shaft member 81 on the lock lever 70 , and the other end is supported by a shaft member 82 on the pressing shaft lever 77 . The lock lever 70, the pressing shaft lever 77 and the link lever 79 constitute a toggle mechanism. The toggle mechanism prevents the pressing member 72 (lock lever 70) from being easily pushed back in the opposite direction even if a pushing force is applied to the pressing member 72 from the lower slide plate 30A. Further, the toggle mechanism expands the operating angle of the pressing member 72 to approximately double the operating angle of the lock lever 70 .

FIG. 6(a) shows a state in which all the drawers 11 are accommodated and locked in the cabinet body 10 by the all-stage lock mechanism 31. FIG. That is, when the slide plates 30A to 30E are lowered to the position restricted by the stopper portion 51 (see FIGS. 1 and 7), the pressing member 72 and the stopper portion 51 move the slide plates 30A to 30E. It regulates. In addition, it is preferable that the lock lever 70 is in a range that does not protrude from the cabinet body 10 when all the drawers 11 are locked.

When the lock lever 70 is moved counterclockwise (in the direction of the arrow) from the state shown in FIG. 6(a), the pressing member 72 is separated from the stopper portion 51 of the slide plate 30A as shown in FIG. 6(b). Then, since the restriction on the upward movement of the slide plate 30A is released, the slide plates 30A to 30E can move upward, and any one of the drawers 11A to 11E can be opened. The stage lock is released. When the lock lever 70 is moved clockwise (in the direction of the arrow) from the state shown in FIG. 6(b), it becomes possible to switch to the all stages locked state shown in FIG. 6(a).

(Action of lock mechanism)
FIG. 7 shows the lock mechanism 25 when the drawers 11A to 11E are housed in the cabinet body 10. FIG. FIG. 7 shows a state in which any drawer 11 can be opened. 7(a) is a perspective view, FIG. 7(b) is a front view seen from the drawer arrangement side, and FIG. 7(c) is an enlarged view of the portion indicated by circle A in FIG. 7(b). . FIG. 7 omits illustration of the all-stage lock mechanism 31 . In the following description, when the sliders 36A to 36E are not specified and can be described in common, they may be referred to as the slider 36. When the all-stage lock mechanism 31 unlocks the drawer 11, all of the slide plates 30A to 30E are lowered by their own weight.

A stopper member 65 is fixed to the vertical frame 14A below the lowermost slide plate 30E. The stopper member 65 determines the lower position of the connecting portion 47 at the lower end of the slide plate 30E. Therefore, each slide plate arranged above the slide plate 30E is lowered until the connecting portion 47 of the upper slide plate 30 comes into contact with the connecting plate 46 of the lower slide plate 30, and arranged along the groove 50. be done. The slide plate 30A is arranged above the slider 36A. The slide plate 30B is arranged between the sliders 36A and 36B, the slide plate 30C is arranged between the sliders 36B and 36C, the slide plate 30D is arranged between the sliders 36C and 36D, The slider 36E is arranged between the sliders 36D and 36E.

As shown in FIG. 7C, the uppermost slide plate 30A is lowered until the connecting portion 47 abuts on the connecting plate 46 of the lower slide plate 30B. The engaging portion 61 of the lower slide plate 30B is located away from the notch 40 of the upper slider 36A. A gap D2 is formed between 61 and the lower surface 38c of the slider 36A. The roller 56 is at a position with a gap that does not contact the inclined surface 39e of the slider 36A. Since the lock mechanism 31 is released, when the drawer 11A is opened (in the direction of the solid arrow), the inclined surface 39e moves to push up the slide plate 30A (in the direction of the dotted arrow). Since the notch 40 does not engage with the engaging portion 61 of the slide plate 30B in the lower stage, the drawer 11A can be opened. Since the roller 56 rolls along with the movement of the inclined surface 39e, the frictional load between the roller 56 and the inclined surface 39e is extremely small, and the drawer 11A can be easily opened.

In each of the second, third, fourth and fifth stages from the top, the slide plate 30 and the slider 36 arranged respectively have the same positional relationship as the state described in FIG. 7(c). It has become. Therefore, when all the drawers 11 are housed in the cabinet main body 10 and the locking by the all-stage lock mechanism 31 is released, any drawer 11 can be opened.

In this example, since the inclination angle .theta. Therefore, the load for lifting the slide plate 30 against the force for opening the drawer 11 is also reduced. In addition, the movement of each slide plate is insensitive to the amount of movement of the slider 36, and even if the slider 36 is moved slightly (about the amount of rattling of the drawer 11), the upper slide plate 30 is notched 40 It is possible to open the drawer 11 because it does not rise enough to engage the . Incidentally, if the inclination angle θ is in the range of 30±5 degrees, it is possible to obtain the above effects. Therefore, in the present invention, the angle in this range is defined as "approximately 30 degrees".

Next, the relationship between the adjacent upper and lower sliders 36 and the slide plate 30 disposed therebetween will be described with reference to FIG. 7(b). L1 is the longest length from the engaging portion 61 of the slide plate 30C to the roller 56 (the length from the end of the engaging portion 61 to the end of the roller 56 in the direction along the groove 50 that is the longitudinal direction of the slide plate 30). The distance between the lower surface 38c of the slider body 38 of the slider 36B and the upper surface 38b of the slider body 38 of the slider 36C (same position as the upper surface 39c of the operating member 39) is L2, and the bottom surface 40a of the notch 40 of the slider 36B and the slider The dimensions are set so that L3>L1 and L1>L2, where L3 is the distance from the upper surface 38b of 36C. With this configuration, when one of the drawers 11 is opened, the prevention of opening the other drawers 11 will be described with reference to FIG.

FIG. 8 is a diagram showing the lock mechanism 25 in a state where the third drawer 11C from above is opened. The all-stage lock mechanism 31 unlocks the slide plates 30A to 30E. When the drawer 11C is opened, the roller 56 pushes the slide plate 30C upward while getting over the inclined surface 39e. The engaging portion 61 of the slide plate 30C enters the notch 40 of the slider 36B. The slide plate 30C pushes up the slide plate 30B with the connecting plate 46 fixed to the slide plate 30C, and the engaging portion 61 of the slide plate 30B enters the notch 40 of the slider 36A. The slide plate 30B pushes up the slide plate 30A with a connecting plate 46 fixed to the slide plate 30B. Due to such action, the drawers 11B and 11A above the opened drawer 11C cannot be opened. This will be explained in more detail with reference to FIG.

The drawers 11D and 11E below the drawer 11C are lowered until the slide plate 30E comes into contact with the stopper member 65 as shown in FIG. The slide plate 30D is lowered until it contacts the connecting plate 46 of the slide plate 30E. That is, when the drawer 11D is to be opened, the inclined surface 39e of the slider 36E pushes up the slide plate 30E. Then, the engaging portion 61 of the slide plate 30D comes into contact with the lower surface 38c of the slider 36C and stops. That is, the slide plate 30D is locked between the slider 36C and the inclined surface 39e of the slider 36D, and the drawer 11D cannot be opened. When an attempt is made to open the drawer 11E, the slide plates 30D and 30E are locked between the slider 36C and the inclined surface 39e of the slider 36E, and the drawer 11E cannot be opened. This will be explained in more detail with reference to FIG.

FIG. 9 shows a state in which the drawers 11A and 11B above the opened drawer 11C are locked. The slide plate 30C is pushed up by a slider 36C. The locking portion 61 of the slide plate 30C enters the notch 40 of the slider 36B. When an attempt is made to open the drawer 11B, the wall portion 40b of the notch 40 of the slider 36B engages with the engaging portion 61 of the slide plate 30C, so the drawer 11B cannot be opened. The slide plate 30B pushed up by the slide plate 30C enters the notch 40 of the slider 36A. When an attempt is made to open the drawer 11A, the wall portion 40b of the notch 40 of the slider 36A engages with the engagement portion 61 of the slide plate 30B, so the drawer 11A cannot be opened. Each roller 56 of the slide plates 30A and 30B is located away from the inclined surface 39e.

For example, when the lowest drawer 11E is opened, the upper drawers 11A to 11D cannot be opened. When the lowermost drawer 11E is opened, if an attempt is made to open the upper drawer 11D, the engaging portion 61 of the lower slide plate 30E is caught in the notch 40 of the upper slider 36D. 11D cannot be opened. When an attempt is made to open the drawer 11C, the locking portion 61 of the lower slide plate 30D is caught in the notch 40 of the upper slider 36C, so the drawer 11C cannot be opened. The upper drawers 11A and 11B cannot be opened by the action described with reference to FIG.

FIG. 10 shows a state in which the drawers 11D and 11E below the opened drawer 11C are locked. When the drawer 11C is opened, the lower slide plates 30D and 30E are lowered to a position where the slide plate 30E contacts the stopper member 65. As shown in FIG. When the drawer 11D is to be opened, the roller 56 of the slide plate 30D tries to push up the slide plate 30D by the inclined surface 39e of the slider 36D. However, the engaging portion 61 of the slide plate 30D hits the lower surface 38c of the slider 36C that is pulled out, and cannot be pushed up any further. The roller 56 stops without getting over the inclined surface 39e of the slider 36D. That is, since the slide plate 30D is locked between the inclined surface 39e of the slider 36D and the lower surface 38c of the upper slider 36C, the drawer 11D cannot be opened.

When an attempt is made to open the drawer 11E, the roller 56 of the slide plate 30E tries to push up the slide plate 30E due to the movement of the inclined surface 39e of the slider 36E. The slide plate 30E pushes up the slide plate 30D by the connecting plate 46, hits the lower surface 38c of the slider 36C from which the engaging portion 61 of the slide plate 30D is pulled out, and cannot be pushed up any further. The rollers 56 of the slide plate 30E stop without getting over the inclined surface 39e of the slider 36E. That is, since the slide plate 30E is locked between the inclined surface 39e of the slider 36E and the lower surface 38c of the slider 36C via the slide plate 30D, the drawer 11E cannot be opened.

For example, when the top drawer 11A is opened, the lower drawers 11B to 11E cannot be opened. When the top drawer 11A is opened and the bottom drawer 11E is opened, the roller 56 of the slide plate 30E moves the inclined surface 39e of the slider 36E. However, the slide plate 30E pushes up the slide plate 30D, the slide plate 30C, and the slide plate 30B in that order. That is, the slide plates 30E, 30D, 30C, and the slide plate 30B are locked between the inclined surface 39e of the slider 36E and the lower surface 38c of the uppermost slider 36A, so the drawer 11E cannot be opened.

When an attempt is made to open the drawer 11D, the inclined surface 39e of the slider 36D tends to move. However, the slide plate 30D pushes up the slide plate 30C and then the slide plate 30B in that order, and the locking portion 61 of the slide plate 30B hits the lower surface 38c of the slider 36A and cannot be pushed up further. That is, since the slide plates 30D, 30C, and 30B are locked between the inclined surface 39e of the slider 36D and the lower surface 38c of the uppermost slider 36A, the drawer 11D cannot be opened. By the same action, when an attempt is made to open the drawer 11C, the slide plates 30C and 30B are locked between the inclined surface 39e of the slider 36C and the lower surface 38c of the uppermost slider 36A, and the drawer 11C cannot be opened. When an attempt is made to open the drawer 11B, the slide plate 30B is locked between the inclined surface 39e of the slider 36B and the lower surface 38c of the upper slider 36A, and the drawer 11B cannot be opened.

As described above, in the drawer 11 above the opened drawer 11, the locking portion 61 of the slide plate 30 provided corresponding to the opened drawer 11 is replaced by the notch of the upper slider 36. By entering 40, it becomes impossible to open. On the other hand, the drawer 11 on the lower side of the open drawer 11 should be opened between the inclined surface 39e of the slider 36 of the drawer 11 to be opened and the lower surface 39f of the slider 36 of the open drawer 11. The slide plate 30 interposed between the drawer 11 to be pulled out and the drawer 11 being pulled out is locked, so that the drawer 11 cannot be opened.

The cabinet 1 is a cabinet in which when one drawer 11 is opened, other drawers 11 cannot be opened on the side where the one drawer 11 is open. The cabinet 1 has an inclined surface 39e that continues from the tip surface 39d on the side where the drawer 11 is opened to the top surface 39c, and a notch 40 at the intersection of the tip surface 39d and the bottom surface 38c that is parallel to the top surface 39c (upper surface 38b). , a slider 36 fixed to the side surface of the drawer 11, and a groove 50 formed in the vertical frame 14A constituting the cabinet body 10 and perpendicular to the floor surface in which the cabinet 1 is arranged, and the groove 50 , and has a lock mechanism 25 composed of a plurality of slide plates 30A to 30E provided corresponding to each stage of the drawer 11. As shown in FIG.

When the drawer 11 is opened, the inclined surface 39e of each slide plate moves to the side where the drawer 11 is opened (movement of the inclined surface 39e). A roller 56 configured to lift the plate 30, a locking portion 61 capable of entering the notch 40 of the slider 36 arranged at the upper stage, and a push-up for pushing up the slide plate 30 arranged at the upper stage. It has a connection plate 46 as a part and a connection part 47 that can be connected to the connection plate 46 of the slide plate 30 arranged in the lower stage. In the drawer 11 above the opened drawer 11, the notch 40 of the slider 36 of the drawer 11 to be newly opened engages with the engaging portion 61 of the slide plate 30 to lock the slider 36. . In the drawer 11 lower than the opened drawer 11, the slide is provided between the inclined surface 39e of the slider 36 of the drawer 11 to be newly opened and the lower surface 38c of the opened slider 36. The plate 30 is configured to be locked.

By constructing the cabinet 1 in this way, when one of the plurality of drawers 11 is to be opened, the engaging portion 61 of the slide plate 30 on the lower stage of the drawer 11 is a slider to be opened. 36 notches 40 are not engaged. Further, since the upper slide plate 30 of the drawer 11 to be opened fits into the notch 40 of the upper slider 36, the drawer 11 can be opened. The drawer 11 above the opened drawer 11 cannot be opened because the engaging portion 61 of the slide plate 30 engages the notch 40 of the slider 36 of the drawer 11 to be opened. The drawer 11 on the lower side of the open drawer 11 is located between the open drawer 11 and the open drawer 11 between the inclined surface 39e of the slider 36 of the drawer 11 to be opened and the lower surface 38c of the slider 36 that is to be opened. The slide plate 30 between the drawer 11 to be opened and the drawer 11 is pinched and locked so that the drawer cannot be opened.

The slide plates 30A to 30E are arranged along the groove 50 provided in the vertical frame 14A and move up and down along the groove 50, so that each slide plate has straightness, so that each slide plate does not bend. It is possible to move smoothly with low load. Further, since the slide plates 30A to 30E have the rollers 56, it is possible to reduce the frictional load between the slide plates 30A to 30E and the inclined surface 39e of the slider 36, thereby suppressing wear and having excellent durability.

By constructing the cabinet 1 in this way, the drawer 11 desired to be opened can be opened, the opening of the drawers 11 other than the opened drawer can be reliably prevented, and the cabinet has excellent durability. 1 can be realized.

In the cabinet 1, the longest length between the roller 56 and the engaging portion 61 is L1, and the lower surface 38c of the upper slider 36 and the lower slider 36 of the two sliders 36 adjacent to the upper and lower stages are L1. When the distance from the upper surface 38b (39c) is L2, and the distance between the bottom surface 40a of the notch 40 of the upper slider 36 and the upper surface 38b (39c) of the lower slider 36 is L3, L3>L1 and L1>L2. is configured to be

By setting L1, L2, and L3 in this manner, one of the plurality of drawers 11 can be opened, and the opening of drawers 11 other than the opened drawer 11 can be reliably prevented. .

In the cabinet 1, the connecting plate 46 as a push-up portion provided on each slide plate and the protrusion 47a that is part of the connecting portion 47 are inserted into the groove 50, and each slide plate is configured to be movable along the groove 50. It is By configuring in this way, it is possible to suppress bending between the slides, which hinders movement, and to smoothly move each slide plate with a low load.

In the cabinet 1, the rollers 56 are supported by bearings 55 on each slide plate. Each slide plate is moved upward by the inclined surface 39 e of the slider 36 . At this time, since the roller 56 that contacts the inclined surface 39e has the bearing 55, the load can be suppressed. For example, even when the weight of all slide plates 30A to 30E is supported by one roller 56, the load can be reduced. In addition, it is possible to suppress the load when opening the drawer 11 so that the drawer 11 can be opened smoothly. Further, it is possible to improve durability by suppressing wear of the inclined surface 39e.

Further, when the drawers 11A to 11E are accommodated in the cabinet body 10, the slider 36 is positioned between the locking portion 61 and the wall portion 40b perpendicular to the upper surface 39c of the notch 40. A gap D1 is provided in the movement direction, and the inclination angle θ of the inclined surface 39e (the angle formed by the inclined surface 39e with respect to the upper surface 39c of the slider 36) is set to about 30 degrees.

The tilt angle of the operating member 39 at the tip of the extensible member described in the aforementioned Patent Document 2 is set to 45 degrees, and the slide plate 30 is moved sensitively to a slight movement of the inclined surface 39e (movement of the drawer 11), There is a possibility that the drawer 11 cannot be opened. On the other hand, the inclination angle .theta. of this example is approximately 30 degrees, and the movement of the slide plate 30 is insensitive to the movement of the inclined surface 39e. Also, the load for raising the slide plate 30 against the movement of the slider 36 is small. Further, since there is a gap D1 between the engaging portion 61 of the slide plate 30 and the notch 40 of the slider 36, the slide plate 30 does not react to the movement of the drawer 11 to the extent of rattling. As a result, one of the drawers 11 can be opened, and the opening of the drawers 11 other than the opened drawer 11 can be reliably prevented.

The uppermost slide plate 30A restricts the upward movement of the slide plate 30A by the all-stage lock mechanism 31 that locks the drawers 11 of all the stages so that they are stored inside the cabinet 1. A stopper member 65 that regulates the position to which the slide plate 30E descends is arranged below the slide plate 30E that has the stopper portion 51 and is arranged in the lowest stage.

With this configuration, the vertical movement of the slide plates 30A to 30E can be restricted. The cabinet 1 is configured such that each slide plate is moved by the inclined surface 39e of the slider 36 to open or lock the drawer 11. As shown in FIG. Therefore, the drawers 11A to 11E can be prevented from being opened by restricting the movement of each slider with the all-stage lock mechanism 31 and the stopper member 65. FIG. By locking all of the drawers 11A to 11E, it is possible to prevent the drawers 11A to 11E from opening when the cabinet 1 containing articles is transported or shaken or shaken. Become.

Further, the all-stage lock mechanism 31 includes a lock lever 70 pivotally supported by a lock lever mounting plate 71 by a shaft member 75 serving as a first rotating shaft, a pressing member 72 for regulating the upper position of the stopper portion 51 , and a shaft member 75 . has a presser shaft lever 77 pivotally supported by a shaft member 78 which is a second rotating shaft at a remote position, and a link lever 79 connecting the lock lever 70 and the presser shaft lever 77, and the lock lever 70 , the pressing member 72 can be switched between a position for restricting the movement of the slide plate 30A and a position for releasing the restriction.

By using the all-stage lock mechanism 31 having such a configuration, it is possible to pull out either the all-stage locked state in which all stages of the drawer 11 cannot be opened or the all-stage drawer 11 by operating the lock lever 70.例文帳に追加It is possible to easily switch between the unlocked state and the unlocked state in which it is possible to Since the all-stage lock mechanism 31 is a toggle mechanism, the clamping force is large, and the push-up force from the lower slide plate 30A does not push back the pressing member 72 (lock lever 70) in the opposite direction. By operating the lock lever 70, it is possible to easily switch between a fully locked state and a fully unlocked state.

The cabinet 1 has a first target mark 32 and a second target mark 33 for detection by the visual sensor. The mark 33 is provided on the surface of the table facing the visual sensor.

By thus providing the first target mark 32 and the second target mark 33 and detecting them with the visual sensor, the relative positions of the cabinet body 10 and the table with respect to the manipulator can be detected. Also, the first target mark 32 is used to recognize whether the cabinet 1 is an object to be conveyed, the second target mark 33 is used to identify each stage of the table, and the placed article is reliably grasped by the manipulator and conveyed. becomes possible.

(Second embodiment)
Then, the structure of the cabinet 1 which concerns on 2nd Embodiment is demonstrated. The cabinet 1 according to the first embodiment has a configuration in which the drawers 11A to 11E can be opened only in one direction on the front side. In contrast to this, the cabinet 1 according to the second embodiment has a configuration in which the drawers 11A to 11E can be opened in both the front side of the cabinet body 10 and the back side opposite to the front side. be. The second embodiment is realized by changing the position of the lock mechanism 25 including the all-stage lock mechanism 31 shown in FIGS. I will explain while

In the second embodiment, the right side slide rail 23 shown in FIG. 1 has the same configuration as the left side slide rail 22 . However, the operating member 39 is arranged on the rear side of the slider main body 38 of the slide rail 22 . That is, the slide rail 23 is attached to the right fixed rail 35 with the operating member 39 directed toward the back side. The slide rails 22 and 23 are configured to be slidable to both the front side and the back side shown in FIG. Although not shown, the fixed rail 35 is provided with a stopper for fully opening the drawers 11A to 11E toward the front and a stopper for fully opening the drawers 11A to 11E toward the back. The same groove 50 as in the vertical frame 14A is formed in the vertical frame 14C on the far right side shown in FIG. By providing the lock mechanisms 25 including the all-stage lock mechanism 31 on the left front side and the right rear side of the cabinet body 10, when one of the drawers 11A to 11E is opened on the front side, the left front lock mechanism 25 operates, When one of the drawers 11A to 11E is opened to the rear side, the lock mechanism 25 on the right rear side is activated.

Note that the lock mechanism 25 can be configured to be attached to the vertical frames 14B and 14D. For example, the stopper portion 51 of the uppermost slide plate 30A is projected in the direction in which the drawer 11 is opened, and the all-stage lock mechanism 31 is arranged so that the pressing member 72 is positioned above the stopper portion 51 . By configuring in this way, it becomes possible to attach the lock mechanism 25 to the vertical frames 14B and 14D. By attaching the lock mechanism 25 to the vertical frame 14A and the vertical frame 14B, and attaching the operating member 39 to both ends of one slider 36 on the front side and the back side, any one of the drawers 11 can be locked on the front side and the back side. A cabinet 1 that can be opened on both sides can be realized. In such a configuration, the slide rail 23 arranged on the right side can have a simple configuration without the operating member 39 .

In the cabinet 1 of the second embodiment, the drawers 11A to 11E can be opened to both the front side of the cabinet body 10 and the back side opposite to the front side. The lock mechanism 25 is arranged on both the front side and the back side of the cabinet body 10 . With such a structure, the desired drawer 11 can be opened on both the front side and the back side, and when one drawer 11 is opened, the other drawers 11 cannot be opened. Also, when one drawer 11 is opened on the front side, it is also possible to open one drawer 11 on the back side.

Also, with such a configuration, it is possible to feed and remove articles from both the front side and the back side of the cabinet 1, for example. Alternatively, it is possible to open one of the drawers 11 on the front side to remove materials, while the other drawer 11 on the back side is opened to supply materials. Also, if the first target mark 32 and the second target mark 33 are arranged on both the front side and the back side of the cabinet body 10 and the table, the cabinet 1 can be transported regardless of the direction to the manipulator. can be placed.

The drawer lock mechanism 25 is a lock mechanism that prevents the opening of the other drawers 11 in the same direction when one drawer 11 is opened. The lock mechanism 25 has an inclined surface 39e that continues from the tip surface 39d on the side that opens the drawer 11 to the top surface 39c, and a notch 40 at the intersection of the tip surface 39d and the bottom surface 38c that is parallel to the top surface 39c (upper surface 38b). A slider 36 fixed to the side surface of the drawer 11 and a groove 50 perpendicular to the floor surface formed in the vertical frame 14A constituting the cabinet body 10 are arranged along the groove 50 and are movable along the groove 50. , and slide plates 30A to 30E provided corresponding to each stage of the drawer 11. As shown in FIG.
