  Examples of the present invention will be described below. In addition, description of an Example is an illustration and this invention is not limited to the following description.

  A weighing device (hereinafter also referred to as a weighing device) in which a tank support housing according to an embodiment of the present invention is used will be described with reference to FIGS. FIG. 1 is an exploded perspective view of the weighing device, and FIGS. 2 to 4 are a perspective view, a front view, and a side view showing a usage state of the weighing device.

  As shown in the figure, the weighing apparatus 1 includes a weighing mechanism unit 10 that weighs an object to be weighed, a weight placing table 20, and a test weight 30 placed on the weight placing table 20.

  The weighing mechanism unit 10 includes a base 11 serving as a support member for supporting the whole, a load cell 12 provided on the base 11, and a plurality of actuators 13 serving as a weighing table lifting means disposed on the load cell 12. A weighing table 14 is provided on the actuator 13.

  The actuator 13 is a fluid pressure (for example, hydraulic) cylinder that can move the weighing platform 14 up and down so as to be freely positioned. It is also possible to use a mechanical lifting device.

  The weighing table 14 is capable of supporting a movable large tank (tank) 100 that is a part of the object to be weighed, and is supported by the load cell 12 so that it can be moved up and down while maintaining a horizontal state. . The weight mounting table 20 is provided on the base 11 without being buffered with the weighing table 14, and the weight mounting table 20 is provided with two through portions 21 where the weight 30 is mounted.

  On the weighing table 14, support portions 41 are provided at two locations, and the support portions 41 are formed in a shape that can penetrate the penetration portion 21 of the weight mounting table 20 and are provided at the position of the penetration portion 21. The support portion 41 rises through the penetrating portion 21 when the weighing platform 14 is raised, and supports the weight 30.

  The tank 100 weighed by the weighing device 1 is detachably attached to a gantry 120 as a tank support housing. The gantry 120 includes a main body 110 as a casing main body, and the main body 110 includes a tank holding portion 111 into which the tank 100 is inserted. Specifically, the tank holding part 111 is a recessed part having a bottom part, and is formed as a space in which the lower part of the tank 100 can be stored in the recessed part. The opening shape of the tank holding part 111 should just be formed larger than the outer diameter of the tank 100, and there may be play between the outer peripheral surface of the tank 100 and the inner surface of the tank holding part 111.

  In the main body 110, a flange portion 112 is formed at the opening of the tank holding portion 111. The tank 100 is provided with a fixing piece 113 that is fixed to the flange portion 112 when the tank 100 is held by the tank holding portion 111. By fixing the fixed piece 113 to the flange portion 112, the tank 100 is fixed to the main body 110.

  The opening shape of the tank holding part 111 is set to a size that can accommodate all the tanks of various sizes that are scheduled to be used. In this case, although the size of the play generated between the tank holding portion 111 and the outside diameter of the tank also changes, the size of the fixed piece 113 is such that the tank 100 is fixed to the flange portion 112 via the fixed piece 113. What is necessary is just to select a sheath shape. By appropriately designing the fixed piece 113, the tank support housing can hold the tank 100 of various sizes.

  In addition, the tank holding | maintenance part 111 is not restricted to such an aspect, For example, you may form as a through-hole which the tank 100 can penetrate. In this case, the tank 100 is fixed to the flange portion 112 via the fixing piece 113 while being accommodated in the tank holding portion 111 as a through hole.

  One end of four foot frames 121 is provided in the main body 110, two first frames 122 that connect the two foot frames 121, and two second frames 123 (frames) that connect the first frames. And. Further, casters 124 are provided on the four leg frames 121, and the gantry 120 can be moved to an arbitrary position.

  In the above-described embodiment, as the weighing table 14 is raised by the actuator 13, the two second frames 123 (a not-shown contact reference portion) come into contact with the weighing table 14, and the gantry 120 is supported by the weighing table 14 (lifted). ). With the tank 100 attached to the gantry 120, the weight of the tank 100 is weighed together with the gantry 120.

  That is, the main body 110 includes a second frame 123 disposed above the weighing table 14 when the weighing table 14 is in the lowered position, and a tank holding unit 111 in which the tank 100 is detachable above the second frame 123. have. For this reason, tanks of different sizes can be supported by the gantry 120 which is a common tank support housing, and even if the tank is changed, the gap between the weighing platform 14 and the second frame 123 is minimized. The second frame 123 can be arranged with high rigidity while maintaining.

  Therefore, even if a plurality of different tanks are used in the common gantry 120, the gap between the weighing platform 14 and the second frame 123 can be kept to a minimum, and the stroke of the actuator 13 can be reduced.

  Here, if the stroke of the actuator 13 is very small, the position of the second frame 123 relative to the ground plane on which the base 11 is placed is required to be highly accurate.

  In other words, the second frame 123 must be higher than the weighing platform 14 in the state where the actuator 13 is lowered to the lowest position (the lowest point). If it is lower than this, the second frame 123 collides with the weighing table 14 when the gantry 120 is moved in the lateral direction, and the second frame 123 cannot be arranged on the weighing table 14. In addition, the position of the second frame 123 with respect to the ground plane must be lower than the weighing platform 14 in the state where the actuator 13 is fully raised (uppermost point). If it is higher than this, even if the actuator 13 reaches the highest point, the weighing platform 14 cannot support the second frame 123.

  That is, the position of the second frame 123 with respect to the ground plane must be higher than the lowest point of the actuator 13 and lower than the highest point. For this reason, the shorter the stroke of the actuator 13 (the difference between the lowest point and the highest point), the more precisely the position of the second frame 123 must be formed.

  As described above, the second frame 123 must be formed with high accuracy. However, if the pedestal 120 is formed for each different tank 100, it takes much time and costs.

  However, according to the present invention, even if different tanks 100 are targeted, one (a number smaller than the number of tanks) of the gantry 120 can be used in common, so the second must be manufactured with high accuracy. There is no need to produce many frames 123. This can contribute to cost reduction of the gantry 120.

  Further, since the tank holding part 111 is arranged above the second frame 123, the second frame 123 and the tank holding part 111 can be arranged at positions separated from each other. For this reason, even if it is a big tank, a tank can be located in the space between the tank holding | maintenance part 111 and the 2nd flame | frame 123, and a large sized tank can be used easily.

  It is possible to weigh the gantry 120 by removing the tank 100 and supporting (lifting) only the gantry 120 on the weighing platform 14.

  The actuator 13 raises the weighing platform 14 to the first state, and the weighing platform 14 abuts on the second frame 123 to support the gantry 120 (tank 100). At this time, the support portion 41 provided on the weighing platform 14 is in a first state where it does not contact the weight 30. Next, the actuator 13 raises the weighing platform 14 from the first state to the second state, and the weighing platform 14 supports the entire gantry 120 (tank 100) and simultaneously supports the weight 30 by the support portion 41. Thus, the weight 30 is weighed.

  In this way, the single actuator 13 can be used as both the weighing lifting means for the gantry 120 (tank 100) and the weighing lifting means for the weight 30, and there is no need to provide another actuator. This can contribute to a reduction in the number of points and downsizing.

  In the embodiment described above, the load cell 12 is arranged at the lowermost part and the actuator 13 is arranged thereon, so that weighing can be performed stably.

  The operation of the weighing device 1 configured as described above will be described with reference to FIGS.

  FIG. 5 shows a state in which the gantry 120 with the empty tank 100 fixed on the weighing device 1 is moved and the weighing gantry 14 is arranged below the second frame 123 of the gantry 120. In this state, there is no load on the weighing table 14.

  FIG. 6 shows a situation in which the weight of the gantry 120 (tank 100) is weighed (tare).

  The weighing table 14 is raised to the first state by the actuator 13, the platform 120 (tank 100) is lifted and supported by the weighing table 14, and the load applied to the weighing table 14 is transmitted to the load cell 12 (first state). . In the first state, the weighing platform 14 rises to a state where the support portion 41 does not come into contact with the weight 30 placed on the penetrating portion 21 of the weight placement table 20. Thereby, the weight of the gantry 120 (tank 100) is weighed. This state is set as a zero point.

  Hereinafter, in the weighing apparatus 1, when the object to be weighed is introduced into the tank 100, the weight excluding the tare (weight of the object to be weighed) is weighed by the load cell 12.

  FIG. 7 shows a situation in which the weighing device 1 is tested and calibrated as necessary.

  The weighing platform 14 is further raised by the actuator 13 to be in the second state. In this state, the gantry 120 (tank 100) is supported by the weighing platform 14, and the weight 30 is supported by the support portion 41. Thereby, the load by the weight 30 is transmitted to the load cell 12, and the weight 30 is weighed.

  As the weight 30, one having a weight corresponding to the weight of the content introduced into the tank 100 and weighed thereafter is used. That is, when weighing 50 kg of contents, a 50 kg weight 30 is used, and when weighing 100 kg contents, a 100 kg weight 30 is used. Although one weight 30 is shown in the drawing, two weights may be used depending on the weight, and in this case, the total weight of the two may be the weight of the content to be weighed.

  Then, as a result of weighing the weight 30, if the weight value in the load cell 12 and the weight of the weight 30 are different, the weight value in the load cell 12 is calibrated. In this way, since the test can be performed with the tare placed on the gantry 120 (tank 100), the weighing can be easily performed.

  Thereafter, the weighing table 14 is lowered to the first state by the actuator 13, the weighing object is introduced into the tank 100, and the introduced weighing object is weighed.

  As described above, by moving the gantry 120 on which the tank 100 is detachably held to the site of the weighing device 1, the weighing device 1 is arranged below the gantry 120 and the large tank 100 is weighed. Is possible. Then, by simply placing the weighing device 1 below the gantry 120 and placing the weight 30 having a desired weight on the weight mounting table 20, it is easy to measure the tare of the large tank 100 and to verify the weighing device 1. Therefore, accurate weighing of the object to be weighed can be easily performed.

  As mentioned above, although one Example of this invention was described, the basic composition of the weighing apparatus 1 using the mount frame 120 of this invention is not limited to what was mentioned above. For example, although the means for raising and lowering the weighing table 14 is provided on the load cell 12, the present invention is not limited to this. For example, a means for raising and lowering the weighing table 14 may be provided below the load cell.

  Further, although the weight mounting table 20 is positioned on the base 11, the weight mounting table 20 may be separately provided without the base 11. Of course, in this case, the positioning needs to be able to be positioned in relation to the support portion 41 on the weighing platform 14.

  Furthermore, although the actuator 13 is employed as the weighing raising / lowering means, the invention is not limited thereto, and any means can be used as long as the weighing table 14 can be moved up and down in the vertical direction.

  The present invention can be used in the industrial field of tank support housings used in weighing devices.
