Description

[Technical Field]

[0001] The present invention relates to a combination weighing device. [Background technology]

[0002] In a conventional combination weighing device, a technique is known in which a trough is formed in a V-shape to supply rod-shaped items such as Vienna sausages one by one to a hopper, and the rod-shaped items are aligned in a single file. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3185732 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the prior art, in order to align stacked rod-shaped objects in a single file in the V-shaped trough described above, it was necessary to make the length of the trough relatively long to ensure the transport distance required to align the objects in a single file.However, this posed a problem in that when the troughs were arranged radially, the size of the device became relatively large.

[0005] Therefore, the present invention has been made in consideration of the above problems, and aims to provide a combination weighing device that can improve the probability of supplying items one by one to a hopper while maintaining the size of the device. [Means for solving the problem]

[0006] A combination weighing device according to one embodiment includes a dispersion table that receives and distributes articles supplied from the outside to its surroundings; a ring-shaped fence that temporarily blocks the articles supplied to the dispersion table; a drive unit that moves the ring-shaped fence up and down relative to the dispersion table; a plurality of radial troughs that are arranged radially around the outer periphery of the dispersion table and transport the articles discharged from the dispersion table in a direction away from the dispersion table; a plurality of hoppers that receive and discharge the articles discharged from each of the radial troughs; and a control unit that controls the operation of the drive unit. The gist of the invention is that notches are provided on the periphery of the dispersion table corresponding to each of the radial troughs, allowing the items on the dispersion table to be discharged toward each of the radial troughs, and when the items are to be supplied to the dispersion table, the control unit lowers the ring-shaped fence to block the items being supplied onto the dispersion table, and when the items are to be discharged from the dispersion table, the control unit raises the ring-shaped fence to maintain a distance between the lower end of the ring-shaped fence and the periphery of the dispersion table that allows each individual item to pass through the notch and be discharged. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a combination weighing device that can improve the probability of supplying articles one by one to a hopper while maintaining the size of the device. [Brief explanation of the drawings]

[0009] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following description of the drawings, identical or similar parts are designated by identical or similar reference numerals. However, it should be noted that the drawings are schematic, and the dimensional ratios and the like may differ from those of the actual parts. Therefore, specific dimensions and the like should be determined with reference to the following description. Furthermore, parts in the drawings may have different dimensional relationships and ratios. In this specification and the drawings, elements having substantially the same functions and configurations are designated by the same reference numerals to avoid redundant description, and elements not directly related to the present invention are not shown.

[0010] (First embodiment) A combination weighing device 1 according to a first embodiment of the present invention will now be described with reference to Figures 1 to 3. Figures 1 and 3 are perspective views illustrating an example of the configuration of the combination weighing device 1 according to this embodiment, and Figure 2 is a view of the example of the configuration of the combination weighing device 1 according to this embodiment as seen from above.

[0011] The combination weighing device 1 according to this embodiment is configured to be able to appropriately perform combination weighing of rod-shaped items such as Vienna sausages.

[0012] As shown in Figures 1 to 3, the combination weighing device 1 according to this embodiment includes a dispersion table 10, a ring-shaped fence 20, a drive unit 30, a plurality of radial troughs 40, a plurality of hoppers (not shown), and a control unit 50.

[0013] The dispersion table 10 receives articles supplied from the outside and distributes them to the surrounding area. The ring-shaped fence 20 temporarily blocks the articles supplied to the dispersion table 10. The drive unit 30 moves the ring-shaped fence 20 up and down relative to the dispersion table 10.

[0014] Each of the multiple radial troughs 40 is arranged radially on the outer periphery of the dispersion table 10, and transports the articles discharged from the dispersion table 10 in a direction away from the dispersion table 10. In other words, each of the multiple radial troughs 40 transports the articles discharged from the dispersion table 10 toward a downstream hopper.

[0015] Each of the multiple hoppers receives and discharges the articles discharged from each of the radiation troughs 40. The control unit 50 controls the operation of the drive unit 30. Here, the hoppers may be pool hoppers or weighing hoppers.

[0016] As shown in Figures 1 to 3, notches 11 are provided on the periphery of the dispersion table 10 corresponding to each of the radiation troughs 40, respectively, to allow articles on the dispersion table 10 to be discharged toward each of the radiation troughs 40.

[0017] When the articles are supplied to the dispersing table 10, the control unit 50 lowers the ring-shaped fence 20 to block the articles supplied onto the dispersing table 10, as shown in FIG.

[0018] On the other hand, when discharging an item from the dispersion table 10, the control unit 50 raises the ring-shaped fence 20 as shown in Figure 3, and maintains a gap S between the lower end 20E of the ring-shaped fence 20 and the peripheral edge 10P of the dispersion table 10 so that a single item can pass through the cutout portion 11 and be discharged.

[0019] According to this configuration, when rod-shaped items such as wiener sausages are put into the dispersion table 10, the ring-shaped fence 20 is lowered to cover the dispersion table 10 to prevent the items from jumping up and flying out, and once the items have settled on the dispersion table 10, the ring-shaped fence 20 is raised to a spacing S that allows one item to slip through, and the item is then discharged from the cutout portion 11.

[0020] 1 and 3, the radiation trough 40 may be provided with a V-shaped groove 21. Here, the V-shaped groove 21 is composed of a bottom 21A and two side surfaces 21B that widen outward in the width direction as they extend upward from the bottom 21A.

[0021] According to this configuration, the articles discharged from the dispersion table 10 to the radiation trough 40 can be aligned in a single file.

[0022] Further, a step portion 22 may be provided in the groove 21 near the dispersion table 10 at a position higher than the bottom 21A of the groove 21. According to this configuration, the step portion 22 can spread the articles discharged from the dispersion table 10 in the horizontal direction.

[0023] The width W of the bottom 21A of the groove 21 may be narrower from the dispersing table 10 toward the hopper. Alternatively, the width of the bottom 21A of the groove 21 may be constant and narrow.

[0024] According to this configuration, the rod-shaped articles arranged side by side are restricted by the side surface 21B, and are discharged while gradually changing their arrangement into a single file.

[0025] Furthermore, in the peripheral portion 10P of the dispersion table 10, the outward portion between adjacent notches 11, i.e., the portion with a sharply pointed tip like a saw blade in FIG. 2, may be provided with an upward protrusion 12 (see FIG. 3).

[0026] The protrusion 12 has a shape that gradually rises from the notch 11 that bites into the center of the dispersing table 10, so that it can guide rod-shaped articles into the notch 11 without damaging them.

[0027] An example of the operation of the combination weighing device 1 according to this embodiment will be briefly described below with reference to FIGS.

[0028] First, as shown in FIG. 1, the control unit 50 instructs the driving unit 30 to lower the ring-shaped fence 20, and the driving unit 30 lowers the ring-shaped fence 20 until the dispersal table 10 is completely hidden.

[0029] Secondly, the articles are supplied from an external supply device onto a dispersion table 10 whose outer periphery is surrounded by a ring-shaped fence 20, and remain on the dispersion table 10. At this time, the dispersion table 10 is vibrating, which disperses the unevenly supplied articles to the surrounding area.

[0030] Third, as shown in Figure 3, the control unit 50 instructs the drive unit 30 to raise the ring-shaped fence 20, and the drive unit 30 raises the ring-shaped fence 20 until a gap S is created between the lower end 20E of the ring-shaped fence 20 and the peripheral edge 10P of the dispersion table 10, allowing a single item to pass through the cutout portion 11 and be discharged, and then maintains that state.

[0031] Meanwhile, the dispersing table 10 repeats intermittent vibrations to guide the articles to the periphery of the dispersing table 10.

[0032] Fourth, the articles guided to the periphery are discharged from the notch 11 onto the step 22 provided on the radial trough 40. At this time, the radial trough 40 corresponding to the emptied hopper starts vibrating, so the articles discharged onto the step 22 of the radial trough 40 are scattered horizontally so as not to overlap in the vertical direction, and then transported from the step 22 to the groove 21 and aligned in a single file before being transported to the hopper (pool hopper).

[0033] According to this embodiment, the articles remaining on the dispersing table 10 can be sent one by one from the radial trough 40 to the hopper. As a result, a state in which one or two articles are supplied to the pool hopper or weighing hopper is maintained, and the desired combination weighing can be achieved.

[0034] Although the present invention has been described in detail using the above-described embodiments, it is clear to those skilled in the art that the present invention is not limited to the embodiments described herein. The present invention can be implemented in modified and altered forms without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description in this specification is intended to be illustrative and explanatory and does not have any limiting meaning on the present invention. [Explanation of symbols]
