Description

[Technical field]

[0001] The present invention relates to an article transport device. [Background technology]

[0002] Generally, in a combination weighing device, a main body to which a drive unit for driving a hopper is attached has a top plate having a horizontally flat surface, and a side surface to which the drive unit is attached.

[0003] For example, there are ones that have a side surface that slopes continuously vertically downward toward the central axis of the body, and this side surface is connected to the top plate (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 3670295 Summary of the Invention [Problem to be solved by the invention]

[0005] In general, in a combination weighing device, it is assumed that the top plate and the side plate are joined by welding. Therefore, as described above, when the side plate and the top plate are joined without being vertically overlapped, there is a problem that the processing becomes difficult and the manufacturing cost increases. In addition, there is a problem that the welding is likely to cause thermal distortion, which reduces the processing accuracy.

[0006] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide an item transport device that can easily join the top plate and side surfaces and prevent a decrease in processing accuracy due to joining. [Means for solving the problem]

[0007] An item transport device in one embodiment has a hopper that temporarily stores items input from outside and then discharges the items downstream, a drive unit that drives the hopper, and a main body to which the drive unit is attached, wherein the main body has a top plate having a flat surface in the horizontal direction and a side to which the drive unit is attached, the side having a first surface that rises vertically and is connected to the top plate, and a second surface that is formed continuously with the first surface, to which the drive unit is attached, and that inclines in a direction toward the central axis of the main body as it moves vertically downward. Effect of the Invention

[0008] According to the present invention, it is possible to provide an article transport device that can easily join the top plate and side surfaces by welding and prevent a decrease in processing precision due to such joining. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In the following description of the drawings, the same or similar parts are given the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of the dimensions are different from the actual ones. Therefore, the specific dimensions should be determined with reference to the following description. In addition, the drawings may include parts with different dimensional relationships and ratios. In this specification and the drawings, elements having substantially the same functions and configurations are given the same reference numerals to avoid repeated explanations, and elements not directly related to the present invention are not illustrated.

[0011] (First embodiment) Hereinafter, with reference to Figs. 1 to 5, a combination weighing device 1 will be described as an example of an item transport device equipped with a transport section in a first embodiment of the present invention.

[0012] Specifically, in this embodiment, as shown in FIG. 1, a combination weighing device 1 is described as an example, which is configured to receive and collect items discharged from multiple hoppers 60 / 70 arranged in a circle in a circular chute 80.

[0013] As shown in FIG. 1, the combination weighing device 1 of this embodiment has a dispersion table 20, a radial feeder 30, a flow rate regulating section 40, a support section 50, a pool hopper 60, a weighing hopper 70, a chute 80, and a timing hopper 90.

[0014] The dispersion table 10 may be configured to supply the articles input from the outside to a plurality of radial feeders 30 arranged around the dispersion table 20 while dispersing the articles.

[0015] Each of the multiple radial feeders 30 is configured to transport the articles supplied from the dispersion table 20 to a pool hopper 60 provided corresponding to each radial feeder 30.

[0016] In this embodiment, the dispersion table 10, the pool hopper 60, the weighing hopper 70, the multiple radial feeders 30, the chute 80, and the timing hopper 90 correspond to a conveying section that receives the articles on the conveying surface and conveys the received articles downstream. In addition, although not shown in the present embodiment, if a booster hopper is disposed downstream of the weighing hopper 70 and upstream of the chute 80, the booster hopper also corresponds to a conveying section.

[0017] Moreover, each radial feeder 30 has a conveying path for conveying the articles, and a flow rate restricting unit 40 is disposed on the conveying path. The flow rate restricting unit 40 is configured to restrict the flow rate of the articles conveyed to the pool hopper 60. Moreover, the support unit 50 is configured to support the flow rate restricting unit 40.

[0018] Each pool hopper 60 is configured to deliver the articles supplied from each radial feeder 30 to a weighing hopper 70 disposed below each pool hopper 60 .

[0019] Each weighing hopper 70 is configured to obtain the weight value of the articles that are delivered from each pool hopper 60 and temporarily stay therein.

[0020] Here, the control unit (not shown) is configured to select, from the combinations of weight values ​​obtained by each weighing hopper, a combination that is within a predetermined tolerance range and is closest to the target value, and to discharge temporarily retained items from the weighing hopper 70 corresponding to that combination into a chute 80 arranged below that weighing hopper 70.

[0021] The chute 80 is configured to supply the articles discharged from each weighing hopper 70 to a timing hopper 90.

[0022] The timing hopper 90 is configured to supply the articles supplied by the chute to, for example, a bag-making packaging machine or the like installed downstream of the conveying device 1.

[0023] In this embodiment, a case will be described in which the pool hopper 60 corresponds to a first hopper that temporarily stores articles input from the outside and then discharges the articles downstream, and the weighing hopper 70 corresponds to a second hopper that temporarily stores articles discharged from the pool hopper 60 and then discharges the articles downstream, but the present invention is not limited to this case. As shown in Figs. 2 and 3, the combination weighing device 1 according to this embodiment further includes a drive unit 10 that drives the pool hopper 60 and the weighing hopper 70, and a main body 100 to which the drive unit 10 is attached.

[0024] As shown in FIGS. 2 and 3, the main body 100 has a top plate 110 having a horizontally flat surface, and a side surface 120 to which the drive unit 10 is attached.

[0025] As shown in FIGS. 3 and 4, the side surface 120 has a first surface 120A and a second surface 120B.

[0026] Here, as shown in FIGS. 3 and 4, the first surface 120A rises vertically and is connected to the top plate 110. As shown in FIG.

[0027] On the other hand, as shown in Figures 3 and 4, the second surface 120B is formed continuously with the first surface 120A, has the driving unit 10 attached thereto, and inclines in a direction toward the central axis O of the main body (see Figure 1) as it moves vertically downward.

[0028] In this way, since the second surface 120B is inclined toward the vertically downward side, any matter adhering to the second surface 120B slides or falls along the second surface 120B. This improves the hygiene of the combination weighing device 1. Furthermore, by inclining the second surface 120B as described above, 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 with the second surface 120B, and the number of parts remaining on the upper surface can be reduced.

[0029] 2, an opening 100A is formed in the second surface 120B. The driving unit 10 is configured to be attached to the main body 100 by being inserted into the opening 100A in a direction from the outside to the inside of the main body 100.

[0030] 4, (1) hygiene at the second surface 120B is improved, while (2) the top plate 110 and the first surface 120A can be welded together while they are vertical, making processing easier and reducing costs. Also, processing accuracy can be improved.

[0031] As shown in FIG. 5, the drive unit 10 has a first motor 14 that drives the pool hopper 60, a second motor 13 that drives the weighing hopper 70, and a load cell 12 that detects the weight of items stored in the weighing hopper 70.

[0032] Here, as shown in Fig. 5, the first motor 14, the second motor 13, and the load cell 12 are arranged in a line in the up-down direction U / L. In the example of Fig. 5, the second motor 13, the load cell 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 of the load cell 12, and the load cell 12 is arranged on the upper side U of the first motor 14.

[0033] Here, among the first motor 14, the second motor 13, and the load cell 12, at least the member arranged on the lowermost side L is arranged offset toward the inside I of the main body 100 with respect to the other members. In the example of Fig. 5, the first motor 14 is arranged offset toward the inside I of the main body 100 with respect to the second motor 13 and the load cell 12.

[0034] In this combination weighing device 1, the height dimension of the components (internal components) of the drive unit 10 arranged inside I of an opening 100A provided on the side surface of the main body 100 is larger than the height dimension of the opening 10A. Therefore, the drive unit 10 can be attached to the side surface of the main body 100 by tilting the drive unit 10 with respect to the opening 100A of the main body 100 and inserting the internal components into the opening 100A.

[0035] That is, according to the above-mentioned configuration, the dimension of the opening 100A in the height direction can be reduced, thereby improving the waterproof performance.

[0036] Furthermore, according to the above-described configuration, the first motor 14 is not disposed directly below the load cell 12, so that the effect of heat generated by the first motor 14 on the load cell 12 is reduced, thereby improving the weighing accuracy.

[0037] According to this embodiment, the top plate portion and the side surfaces can be easily joined by welding, and a decrease in processing accuracy due to such welding can be prevented.

[0038] Although the present invention has been described in detail using the above-mentioned embodiment, it is clear to those skilled in the art that the present invention is not limited to the embodiment described in the present specification. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the present invention defined by the description of the claims. Therefore, the description in this specification is intended to be illustrative and does not have any limiting meaning on the present invention. [Explanation of symbols]
