  By the way, in a processing apparatus that processes a predetermined workpiece (for example, a wafer), the processing tool may be a consumable item, and it is necessary to replace the processing tool depending on the use situation. For this reason, at the manufacturing site, a rack for storing a processing tool is provided near the processing apparatus. A box for accommodating a plurality of processing tools is placed on the rack. An operator removes a used tool from the processing apparatus and stores it in a box, while taking out an unused processing tool from another box and attaching it to the processing apparatus. When a predetermined number of used processing tools are stored in the box, the operator lifts the box and moves it to another location.

  However, many processing tools are heavier than they look, and depending on the weight of the box, it may be a burden on the operator. In this case, it is conceivable to make the total weight of the box visible using a weighing scale as described above. However, as a result of a complicated configuration, it causes a cost increase.

  This invention is made | formed in view of such a point, and it aims at providing the rack which can visually recognize the total weight of a box with simple structure.

The rack of the present invention is a rack provided with a box for storing parts, and a display means for indicating that the total weight of the box has been set to a predetermined weight. The display means has a balance structure, A balance bar that can be tilted according to the total weight of the box, a mounting portion for placing the box on one end of the balance bar, a weight provided on the other end of the balance bar, and a balance bar that can be tilted A support unit that supports the display unit, and a display unit that displays that the box placed on the placement unit has reached a predetermined weight due to the placement unit being lowered, and the display unit tilts the balance bar. If the total weight of the box does not exceed the specified weight, it will not move above the box, and when the total weight of the box reaches the specified weight, the balance bar tilts with the support as a fulcrum To move up the box, Box displays that has reached a predetermined weight.

  According to this configuration, parts are put in the box, and when the total weight of the box reaches a predetermined weight, the balance bar tilts toward the placement unit. Since the display unit moves toward one end of the balance bar as the mounting unit descends, the operator sees the display on the display unit moved to the box side and sets the total weight of the box to a predetermined weight. It can be confirmed. In this way, it is possible to configure the rack with a simple configuration and to visually recognize the total weight of the box.

The rack of the present invention is a rack comprising a box for storing parts, and a display means for indicating that the total weight of the boxes has reached a predetermined weight after the parts are placed. A table that can be tilted according to weight, a support unit that supports the table so that it can tilt, a mounting unit that mounts a box on one end of the table, and a table that is closer to the mounting unit than the support unit. And a display unit for displaying that the box placed on the placement unit has reached a predetermined weight due to the placement unit being lowered, and the display unit tilts the table. If the total weight of the box does not exceed the predetermined weight, the table does not move above the box. When the total weight of the box reaches the predetermined weight, the table urges the support portion as a fulcrum. Tilt downward against the urging force of the means It is moved above the box by box displays that has reached a predetermined weight.

  According to the present invention, the total weight of the box can be visually recognized with a simple configuration.

It is a schematic diagram of the rack which concerns on 1st Embodiment. It is operation | movement explanatory drawing of the rack which concerns on 1st Embodiment. It is explanatory drawing of the rack which concerns on 2nd Embodiment. It is explanatory drawing of the rack which concerns on the modification of 2nd Embodiment.

  The rack according to the first embodiment will be described below with reference to FIG. FIG. 1 is a schematic diagram of a rack according to the first embodiment. FIG. 1A shows a side view of the rack, and FIG. 1B shows a perspective view when the rack is viewed from obliquely upward on the front side. In the following description, a processing tool will be described as an example of a component housed in the box, but the present invention is not limited to this configuration. The box may contain any part without being limited to the processing tool. Moreover, in the following figures, the longitudinal direction of the table will be referred to as the front-rear direction, the side on which the box is placed will be described as the front, and the side on which the weight will be provided will be described as the rear. In addition, the short side direction of the table will be described as the left-right direction.

  As shown in FIG. 1, the rack 1 according to the first embodiment is configured such that a box 3 that can accommodate a processing tool 2 (see FIG. 2) is placed on a table 50. In the rack 1, a table 50 is provided on the upper part of the frame 4 assembled in a lattice shape via a support portion 51. In addition to the box 3, the rack 1 includes display means 5 that indicates that the total weight of the box 3 has reached a predetermined weight.

  The display means 5 has a balance structure that can tilt the table 50 (balance bar) according to the weight of the box 3. The table 50 is formed in a rectangular shape when viewed from above, and a substantially central portion in the longitudinal direction is supported by a support portion 51. At one end (front end) of the table 50, a placement portion 52 for placing the box 3 is provided. The box 3 has a rectangular shape as viewed from above with the top opened. The placement unit 52 is configured to restrict the movement of the box 3 relative to the table 50. Specifically, the mounting portion 52 includes stoppers 52 a and 52 b for positioning the table 50 in the front-rear direction.

  A weight 53 is provided at the other end (rear end) of the table 50. The weight of the weight 53 can be changed as appropriate. As a result, the table 50 is configured to be tiltable about the support portion 51 according to the total weight of the box 3.

  A display unit 54 is provided on the upper surface of the table 50 to indicate that the total weight of the box 3 has reached a predetermined weight. The display unit 54 has a pair of long bodies 55 extending in the front-rear direction on both the left and right sides of the box 3. A gate-shaped column portion 56 is provided on the front end side of the pair of long bodies 55 so as to straddle the upper side of the box 3.

  A display plate 57 is provided on the front surface of the gate-shaped column portion 56 to indicate that the total weight of the box 3 has reached a predetermined weight. For example, as shown in FIG. 1B, characters “STOP” are written on the display board 57. The operator can recognize that the total weight of the box 3 has reached a predetermined weight by visually recognizing the display on the display board 57. Further, a wheel 58 made of casters or the like is provided on the lower surface of the long body 55. Thereby, the display part 54 is comprised so that the upper surface of the table 50 can slide in a longitudinal direction (front-back direction) as a whole. In addition, on the upper surface of the table 50, a stopper 59 for restricting the movement of the display unit 54 toward the weight 53 is provided at the approximate center in the longitudinal direction.

  By the way, in a processing apparatus (for example, a cutting apparatus) that requires precise processing accuracy, a processing tool (for example, a cutting blade) is a consumable item. For this reason, measures are taken so that the processing tool is regularly replaced to always maintain a constant processing accuracy. In this case, a rack for storing a processing tool is provided in the vicinity of the processing apparatus. The worker exchanges the used processing tool with an unused processing tool, and accommodates the used processing tool in a box on the rack. The box containing the predetermined number of used processing tools is moved to another location. Then, a predetermined maintenance process is performed on the processing tool, and the processing tool can be reused.

  When the box containing the used processing tool is moved to a predetermined position, the operator needs to lift the box directly. For this reason, it is desirable to recognize the total weight of the box so that the movement of the box is not a burden. This is because if the processing tool is accommodated until the capacity of the box becomes full without knowing the total weight of the box, it may be difficult to lift the box depending on the weight of the processing tool.

  In this case, for example, it is conceivable to provide a scale under the box so that the operator can visually recognize the total weight of the box. However, a weight scale must be prepared for each box, which is not preferable from the viewpoint of cost. Also, the operator must determine on the spot whether the box can be lifted by looking at the display on the scale.

  Therefore, in the first embodiment, the table 50 on which the box 3 is placed has a balance structure, and the table 50 is tilted according to the total weight of the box 3. For example, when the total weight of the box 3 reaches a predetermined weight (20 kg), the table 50 tilts toward the box 3 and the display unit 54 slides toward the box 3 due to its own weight. As a result, the display board 57 indicated as STOP is moved above the box 3, and the operator can recognize that the total weight of the box 3 has reached 20 kg by looking at the display on the display board 57. . In other words, the operator can recognize that it is difficult to lift the box 3 if the processing tool is accommodated in the box 3 any more. Thus, by utilizing the principle of the lever, the total weight of the box 3 can be recognized only by the mechanical configuration without using an electrical configuration.

  Next, the operation of the rack according to the first embodiment will be described with reference to FIG. FIG. 2 is an explanatory diagram of the operation of the rack according to the first embodiment. FIG. 2A shows a state before the processing tool is stored in the box, and FIG. 2B shows a state after a predetermined number of processing tools are stored in the box.

  As shown in FIG. 2A, an empty box 3 is placed on the placement unit 52. At this time, the table 50 is inclined so that the weight 53 side is lower than the placement portion 52 side. Further, the rear end portion of the long body 55 is in contact with the stopper 59, and the movement of the display portion 54 toward the weight 53 is restricted.

  As shown in FIG. 2B, when the used processing tool 2 is gradually housed in the box 3 and the total weight of the box 3 exceeds a predetermined weight (20 kg), the table 50 tilts around the support portion 51 as a fulcrum. Then, the placement unit 52 is lowered. The front end of the table 50 is in contact with the upper surface of the frame 4, and the table 50 is tilted so that the placement portion 52 side is lower than the weight 53 side. At this time, the display unit 54 is moved forward because the table 50 is tilted. The display board 57 moves above the box 3 and is positioned on the front end side of the table 50 (front side of the rack 1). Thereby, the operator on the front side of the rack 1 can intuitively recognize that the total weight of the box 3 has reached a predetermined weight by looking at the display on the display board 57 (see FIG. 1B). . As a result, the operator does not house the processing tool 2 more than necessary in the box 3 and can ensure safety in the operation of moving the box 3.

  As described above, according to the first embodiment, the processing tool 2 is placed in the box 3, and the table 50 tilts toward the placement unit 52 when the total weight of the box 3 reaches a predetermined weight. Since the display unit 54 moves toward one end of the table 50 due to the lowering of the mounting unit 52, the operator looks at the display of the display unit 54 moved to the box 3 side and the total weight of the box 3 Can be confirmed to have reached a predetermined weight. Thus, by utilizing the principle of the lever, it is possible to configure the rack 1 with a simple configuration and visually recognize the total weight of the box 3.

  Next, a rack according to a second embodiment will be described with reference to FIG. FIG. 3 is an explanatory diagram of a rack according to the second embodiment. FIG. 3A shows a state before the processing tool is stored in the box, and FIG. 3B shows a state after a predetermined number of processing tools are stored in the box. In the first embodiment, the weight is provided on the rear end side of the table. However, in the second embodiment, the first embodiment is provided in that a biasing means (spring) is provided on the front end side of the table. It is different from the form. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  As shown in FIG. 3, in the rack 7 according to the second embodiment, the rear end side of the table 70 is supported by a support portion 51 so as to be tiltable. Further, an urging means 71 for urging the table 70 from below is provided on the front end side (the mounting portion 52 side) of the table 70. Specifically, the urging means 71 is composed of, for example, a compression coil spring, one end is fixed to the upper surface of the frame 4, and the other end is fixed to the lower surface of the table 70.

  The table 70 is urged upward by the urging force of the urging means 71. Thereby, as shown in FIG. 3A, the table 70 is inclined so that the rear end side is lower than the front end side of the table 50 when the box 3 is empty. Further, as in the first embodiment, the rear end portion of the long body 55 is in contact with the stopper 59, and the display portion 54 is restricted from moving to the rear end side of the table 70.

  When the used processing tool 2 is gradually accommodated in the box 3 and the total weight of the box 3 exceeds a predetermined weight (20 kg), the table 70 resists the urging force of the urging means 71 and supports 51. Tilt to the fulcrum. As a result, as shown in FIG. 3B, the front end side (mounting portion 52) of the table 70 is lowered, and the table 70 is inclined so that the front end side is lower than the rear end side.

  At this time, the display unit 54 is moved forward because the table 70 is tilted. The display board 57 moves above the box 3 and is positioned on the front end side of the table 70 (front side of the rack 1). Thereby, the operator on the front side of the rack 1 can intuitively recognize that the total weight of the box 3 has reached a predetermined weight by looking at the display on the display board 57 (see FIG. 1B). .

  Thus, also in the second embodiment, the rack 7 can be configured with a simple configuration and the total weight of the box 3 can be visually recognized. In particular, in FIG. 3, by providing the urging means 71 instead of the weight 53 (see FIGS. 1 and 2), a space for providing the weight 53 on the rear side of the support portion 51 becomes unnecessary. For this reason, the front-rear length of the table 70 can be shortened compared to the first embodiment.

  Next, a modified example of the second embodiment will be described with reference to FIG. FIG. 4 is an explanatory diagram of a rack according to a modification of the second embodiment. FIG. 4A shows a state before the processing tool is stored in the box, and FIG. 4B shows a state after a predetermined number of processing tools are stored in the box. In the second embodiment, the display unit is configured to slide on the table with wheels. However, the modification is different from the second embodiment in that the display unit is configured to swing. Hereinafter, the same components as those of the second embodiment are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  As shown in FIG. 4, in the rack 8 according to the modified example, a gate-shaped column part 82 constituting the display unit 81 is formed in a substantially L shape in a side view. Specifically, the column part 82 is connected so that the long part 83 and the short part 84 form a right angle in a side view, and the display plate 57 is provided on the distal end side of the long part 83. A connecting portion between the long portion 83 and the short portion 84 is supported by a support portion 85 provided at the upper center of the frame 4. Thereby, the display part 54 is comprised so that the support part 85 can be rock | fluctuated as a fulcrum as a whole.

  A long hole 86 extending in the extending direction of the short portion 84 is formed at the tip of the short portion 84. A shaft portion 87 provided on the side surface of the table 70 is inserted into the long hole 86, and the short portion 84 is supported by the shaft portion 87. The shaft portion 87 is provided on the side surface of the table 70 substantially below the center in the front-rear direction of the placement portion 52.

  In the rack 8 configured as described above, as shown in FIG. 4A, when the box 3 is empty, the rack 8 is inclined so that the rear end side is lower than the front end side of the table 70. At this time, the display part 54 is inclined so that the long part 83 is located behind the box 3. Further, in the short portion 84, the shaft portion 87 is located on the distal end side of the long hole 86.

  When the used processing tool 2 is gradually accommodated in the box 3 and the total weight of the box 3 exceeds a predetermined weight (20 kg), the table 70 resists the urging force of the urging means 71 and supports 51. Tilt to the fulcrum. As a result, as shown in FIG. 4B, the front end side (mounting portion 52) of the table 70 is lowered, and the table 70 is inclined so that the front end side is lower than the rear end side.

  At this time, the display unit 54 (the column unit 56) rotates around the support unit 85 as a fulcrum according to the tilting operation of the table 70. Specifically, the long portion 83 rotates forward with the support portion 51 as a fulcrum while the shaft portion 87 slides in the long hole 86 toward the proximal end of the short portion 84. Then, as a result of the display board 57 moving above the table 70 toward the box 3, the display board 57 is positioned above the box 3. As a result, an operator on the front side of the rack 8 can intuitively recognize that the total weight of the box 3 has reached a predetermined weight by looking at the display on the display board 57 (see FIG. 1B). . Thus, also in the modified example, it is possible to configure the rack 8 with a simple configuration and to visually recognize the total weight of the box 3.

  In addition, this invention is not limited to the said embodiment, It can change and implement variously. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited thereto, and can be appropriately changed within a range in which the effect of the present invention is exhibited. In addition, various modifications can be made without departing from the scope of the object of the present invention.

  In the above-described embodiment, the used processing tool 2 is exemplified as the component housed in the box 3. However, the present invention is not limited to this configuration. The parts housed in the box 3 may be any parts.

  In the above-described embodiment, the predetermined weight of the box 3 is 20 kg. However, the present invention is not limited to this configuration. The predetermined weight of the box 3 can be appropriately changed according to the operator. For example, when the worker is a woman, it may be changed to 15 kg. In this case, the weight 53 may be lightened, or the weight 53 may be brought closer to the support portion 51 side. That is, in the above-described embodiment (first embodiment), the weight 53 is provided at the rear end of the table 50. However, the present invention is not limited to this structure. In order to adjust the predetermined weight, the weight 53 may be brought closer to the support portion 51 side.

  In the above-described embodiment, “STOP” is displayed on the display board 57, but the present invention is not limited to this configuration. The display board 57 may be displayed in any manner as long as it prompts the operator to pay attention. For example, when the display plate 57 is positioned above the box 3, the box 3 may be covered. Thereby, it becomes impossible to accommodate the processing tool 2 (parts) in the box 3 any more, and the operator can recognize the predetermined weight without displaying characters.

  As described above, the present invention has an effect that the total weight of the box can be visually recognized with a simple configuration, and is particularly useful for a rack including a box for storing a used processing tool.
