In addition, the illustrations are omitted for elements that are not directly related to the present invention.

[0020] (First Embodiment)

[0021] Below, refer to Figure 1 to Figure 5 , a combination weighing device 1 as an example of an article conveying device including a conveying unit in a first embodiment of the present invention will be described.

[0022] Specifically, in this embodiment, if Figure 1 As shown, a combination weighing device 1 is described as an example in which a circular chute 80 receives articles discharged from a plurality of hoppers 60 / 70 arranged in a circular shape and collects the articles.

[0023] like Figure 1As shown, the combined weighing device 1 according to the present embodiment includes a dispersing table 20 , a radiation feeder 30 , a flow rate limiting unit 40 , a support unit 50 , a storage hopper (pool hopper) 60 , a weighing hopper 70 , a chute 80 , and a timing hopper 90 .

[0024] The distributing table 10 may be configured to distribute articles introduced from the outside and supply the articles to a plurality of radial feeders 30 arranged around the distributing table 20 .

[0025] Each of the plurality of radial feeders 30 is configured to convey the articles supplied from the distributing table 20 to the storage hopper 60 provided corresponding to each radial feeder 30 .

[0026] In addition, in the present embodiment, the dispersing table 10, the storage hopper 60, the metering hopper 70, the plurality of radial feeders 30, the chute 80, and the timing hopper 90 are equivalent to a conveying unit that receives the thrown-in articles with a conveying surface and conveys the received articles downstream. In addition, although not shown in the figure in the present embodiment, if a booster hopper is arranged downstream of the metering hopper 70 and upstream of the chute 80, the booster hopper is also equivalent to the conveying unit.

[0027] Each radial feeder 30 has a conveying path for conveying articles, and a flow rate limiting unit 40 is disposed on the conveying path. The flow rate limiting unit 40 is configured to limit the flow rate of articles conveyed to the storage hopper 60. The support unit 50 is configured to support the flow rate limiting unit 40.

[0028] Each storage hopper 60 is configured to deliver the articles supplied from each radiation feeder 30 to a weighing hopper 70 disposed below each storage hopper 60 .

[0029] Each weighing hopper 70 is configured to obtain a weight value of an article delivered from each storage hopper 60 and temporarily stored.

[0030] Here, the control unit (not shown) is configured to select a combination that is within a specified allowable range and closest to the target value from the combinations of weight values ​​obtained by each weighing hopper, and discharge the temporarily retained items from the weighing hopper 70 corresponding to the combination to the chute 80 arranged below the weighing hopper 70.

[0031] The chute 80 is configured to supply the articles discharged from each weighing hopper 70 to the timing hopper 90 .

[0032] The timing hopper 90 is configured to supply the articles supplied from the chute to, for example, a bag making and packaging machine provided at a subsequent stage of the conveyor device 1 .

[0033] In the present embodiment, the storage hopper 60 is equivalent to a first hopper that temporarily receives items thrown in from the outside and then discharges the items downstream, and the weighing hopper 70 is equivalent to a second hopper that temporarily receives items discharged from the storage hopper 60 and then discharges the items downstream. Although the above contents are described, the present invention is not limited to this case.

[0034] In addition, if Figure 2 and Figure 3 As shown, the combination weighing device 1 according to the present embodiment further includes a driving unit 10 that drives the storage hopper 60 and the weighing hopper 70 , and a main body 100 to which the driving unit 10 is mounted.

[0035] Here, if Figure 2 and Figure 3 As shown, the main body 100 has a top plate 110 having a flat surface in a horizontal direction and a side surface 120 on which the driving unit 10 is installed.

[0036] In addition, if Figure 3 and Figure 4 As shown, the side surface 120 has a first surface 120A and a second surface 120B.

[0037] Here, if Figure 3 and Figure 4 As shown, the first surface 120A stands in a vertical direction and is connected to the top plate 110 .

[0038] On the other hand, Figure 3 and Figure 4 As shown, the second surface 120B is formed continuously with the first surface 120A, and the driving unit 10 is installed, and moves toward the central axis O of the main body as it moves toward the lower side in the vertical direction (refer to Figure 1 ) direction.

[0039] In this way, the second surface 120B is inclined as it goes downward in the vertical direction, so that the attached objects on the second surface 120B slide or fall along the second surface 120B. Therefore, the sanitation of the combination metering device 1 can be improved. In addition, by inclining the second surface 120B in the above manner, the mounting surface of the drive unit 10 can also be inclined. Therefore, the upper surface of the drive unit 10 can also be inclined in conjunction, and the number of components retained on the upper surface can be reduced.

[0040] In addition, if Figure 2 As shown in FIG. 1 , an opening 100A is formed in the second surface 120B. The driving unit 10 is configured to be inserted into the opening 100A in a direction from the outside to the inside of the main body 100 and mounted on the main body 100 .

[0041] According to this composition, Figure 4As shown, (1) the sanitation on the second surface 120B can be improved, and (2) the top plate 110 and the first surface 120A can be welded in a vertical state, which makes processing easier and reduces costs. In addition, processing accuracy can also be improved.

[0042] like Figure 5 As shown, the driving unit 10 includes a first motor 14 for driving the storage hopper 60 , a second motor 13 for driving the weighing hopper 70 , and a load sensor 12 for detecting the weight of the articles stored in the weighing hopper 70 .

[0043] Here, if Figure 5 As shown in FIG. 1 , the first motor 14 , the second motor 13 , and the load sensor 12 are arranged in a row in the up-down direction U / L. Figure 5 In the example, the second motor 13 , the load sensor 12 , and the first motor 14 are arranged in this order from the upper side U. That is, the second motor 13 is arranged on the upper side U than the load sensor 12 , and the load sensor 12 is arranged on the upper side U than the first motor 14 .

[0044] Here, at least the components arranged at the lowermost side L among the first motor 14, the second motor 13, and the load sensor 12 are arranged offset to the inner side I of the main body 100 relative to the other components. Figure 5 In the example of FIG. 1 , the first motor 14 is arranged to be offset toward the inner side I of the main body 100 relative to the second motor 13 and the load sensor 12 .

[0045] In the combined metering device 1, the height dimension of the component (internal component) of the driving unit 10 disposed on the inner side I of the opening 100A provided on the side surface of the main body 100 is larger than the height dimension of the opening 10A. Therefore, the driving unit 10 can be attached to the side surface of the main body 100 by tilting the driving unit 10 relative to the opening 100A of the main body 100 and inserting the internal component into the opening 100A.

[0046] That is, according to the above-mentioned configuration, since the dimension of the opening 100A in the height direction can be reduced, the waterproof property can be improved.

[0047] Furthermore, according to the above configuration, since the first motor 14 is not disposed directly below the load sensor 12 , the influence of the first motor 14 on the heat generation of the load sensor 12 is reduced, and the measurement accuracy can be improved.

[0048] According to the present embodiment, the top plate portion and the side surface can be easily joined by welding, and a decrease in processing accuracy due to the welding can be prevented.

[0049] The present invention has been described in detail using the above-mentioned embodiments. It is obvious to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as a modification and variation without departing from the gist and scope of the present invention determined by the description of the scope of the claim. Therefore, the description of this specification is for the purpose of illustration and does not have any limiting meaning on the present invention.
