Description

[Technical field]

[0001] The present invention relates to a combination weighing device, and more particularly to a cover structure for covering an opening portion of a base that supports the entire device. [Background technology]

[0002] 1, the combination weighing device 100 is attached to the top of a base 10 that is rectangular in plan view via four support legs 11. An opening 13 that penetrates vertically is provided in the center of the base 10, into which a discharge chute 12 that slides down and collects the articles is inserted, and a funnel-shaped lower chute 14 is disposed at the lower end of the discharge chute 12. In addition, below the lower chute 14, a timing hopper that works in conjunction with a packaging device (not shown), a metal detector that detects metal contained in the articles as they fall, and the like are disposed.

[0003] As shown in FIG. 1, the base 10 has boxes 10a on three sides surrounding a central opening 13, and the box on the remaining side is removed to expose an open space S from which the lower chute 14 and the timing hopper located below it can be accessed.

[0004] However, if this open space S is left open, there is a risk that foreign matter may enter through the lower chute 14 connected to the discharge chute 12, the timing hopper, and other connecting parts. For this reason, users may request that this open space S be covered with a removable cover. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2022-75207 Summary of the Invention [Problem to be solved by the invention]

[0006] 1, a cover C that is L-shaped when viewed from the side is provided to cover the top surface 13a and the side surface 13b of the open space S. However, when the cover C is removed for cleaning or maintenance, there is a problem of where to place the cover C. In particular, since the base 10 is installed on a stand on the upper stage of the packaging device, placing the cover C in the passage above the stand creates a problem of it getting in the way of cleaning or maintenance work.

[0007] The present invention is intended to solve these problems, and has an object to provide a combination weighing device in which the open space except for the discharge chute of the opening can be easily blocked, and even if the open space is exposed, the cover can be retracted to a position that does not interfere with cleaning or maintenance work. [Means for solving the problem]

[0008] A combination weighing device according to one embodiment includes: A conveying unit that conveys an item supplied from an outside source; a plurality of hoppers that temporarily retain and discharge the articles conveyed from the conveying section; a base that indirectly supports the conveying unit and the plurality of hoppers and has an opening in a vertical direction; a discharge chute that is inserted into the opening and slides down the articles discharged from the hopper; The gist of the invention is that it comprises a cover which, when connected to the base, can be switched between a first state in which it covers a portion of the opening other than the portion occupied by the discharge chute, and a second state in which the other portion is open.

[0009] This has the advantage that, while the cover is connected to the base, the open space other than that occupied by the discharge chute can be blocked or exposed, eliminating the need to worry about where to place the cover when performing cleaning or maintenance work.

[0010] In one embodiment of the combination weighing device, the cover is connected to the base via a hinge and switches between the first state and the second state by rotating about the hinge.

[0011] Moreover, in one embodiment of the combination weighing device, the cover has a first cover body and a second cover body, the first cover body partially covers an upper surface of the opening in a portion different from the portion occupied by the discharge chute, and the second cover body covers a portion of the upper surface of the opening and a side surface of the opening connected to the upper surface, and further, the first cover body and the second cover body are foldably connected via a second hinge, and the second cover body is connected to a base via the hinge.

[0012] This allows the first cover body and the second cover body to be foldable via the second hinge, and furthermore, the second cover body can be foldable via a hinge connected to the base, so that the first cover body and the second cover body can be folded up small and moved to a position that does not interfere with cleaning work, etc. Effect of the Invention

[0013] According to the present invention, it is possible to provide a combination weighing device on the market which not only allows easy opening and closing of the open space connected to the opening, but also allows the cover to be retracted to a position that does not interfere with cleaning work even when the open space is exposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the drawings are schematic, and dimensions, ratios, and the like are different from those of the actual product. In addition, in this specification and the drawings, elements having substantially the same functions and configurations are given the same reference numerals, and duplicated explanations are omitted. Also, parts with well-known configurations are not shown.

[0016] <Configuration of combination weighing device> In Figure 1, a combination weighing device 100 according to one embodiment includes a conveying section 20 that conveys items supplied from the outside, a plurality of hoppers 30 that temporarily retain and discharge items conveyed from the conveying section 20, a base 10 that indirectly supports the conveying section 20 and the plurality of hoppers 30 and has an opening 13 that penetrates vertically, a discharge chute 40 that is inserted into the opening 13 and allows items discharged from the hoppers 30 to slide down, and a cover 50 shown in Figures 2 to 4 that, when connected to the base 10, switches between a first state in which a portion (open space) S of the opening 13 other than the portion occupied by the discharge chute 40 is covered, and a second state in which the different portion (open space) S is open.

[0017] In Fig. 1, the conveying section 20 includes a dispersion feeder 21 at the center of the device and a plurality of radial feeders 22 arranged radially around the dispersion feeder 21. When an article is supplied onto the dispersion feeder 21 from a cross feeder (not shown), the articles on the dispersion feeder 21 are dispersed to the surrounding radial feeders 22 by intermittent vibration of the dispersion feeder 21. Each radial feeder 22 is configured to vibrate at a predetermined amplitude for a predetermined time when the corresponding hopper 30 becomes empty, and to individually supply articles to the corresponding hopper. Since such a conveying section 20 has a well-known configuration, a detailed description thereof will be omitted here.

[0018] The multiple hoppers 30 are arranged correspondingly below the tips of the radially arranged radial feeders 22. These hoppers 30 are composed of multiple pool hoppers 31 on the upper level and an equal number of weighing hoppers 32 arranged on the lower level, so that when the lower level weighing hoppers 32 discharge the combined and selected articles and become empty, the corresponding upper level pool hopper 31 opens and closes to supply articles to the weighing hoppers 32. Each of these hoppers 31, 32 has a well-known configuration, and detailed description thereof will be omitted here.

[0019] The drive units of the conveying unit 20 and the hopper 30 are housed in a casing (not shown), and the casing is supported on the upper part of the base 10 by four support legs 11. An opening 13 that is polygonal in plan view and penetrates vertically is formed in the center of the base 10, and a discharge chute 40 that slides down articles discharged from the hopper 30 is detachably inserted into the opening 13 relative to the base 10.

[0020] The discharge chute 40 has a generally inverted truncated cone shape, and each unit chute divided into four by the four support legs 11 can be inserted between adjacent support legs 11 and is detachably attached to the support legs 11. In addition, a funnel-shaped lower chute 41 is provided below the discharge chute 40.

[0021] Base 10 has a rectangular shape in plan view with opening 13 penetrating vertically in the center, and electronic devices are housed in box interior 10a on three sides surrounding opening 13 in a U-shape in plan view. One side of base 10 is cut out, and horizontal beam 15 is bridged to the side of open space S connected to opening 13, and cover 50 shown in Figures 2 to 4 is attached to horizontal beam 15 via hinge 51.

[0022] The cover 50 is made of stainless steel and has a shape that covers the upper surface 13a and the side surface 13b of the open space S in Fig. 1. In addition, an angle material (reinforcing member) (not shown) is attached to the back surface of the cover 50.

[0023] In addition, since the cover 50 is attached to the base 10 via the hinge 51 shown in Figure 2, the cover 50 can be switched between a first state in which the cover covers a portion of the opening 13 in the central part of the base 10 other than the portion occupied by the discharge chute 40, i.e., the top surface 13a and the side surface 13b of the open space S, and a second state in which the top surface 13a and the side surface 13b are open.

[0024] Furthermore, the cover 50 includes a first cover body 52 that covers a part of the upper surface 13a of the open space S near the center, and a second cover body 53 that covers a part of the upper surface 13a near the outside and the side surface 13b. The first cover body 52 that covers the upper surface 13a and the left and right edge portions E of the second cover body 53 cover the upper surface 10a of the base 10.

[0025] In Figs. 2 to 4, the first cover body 52 and the second cover body 53 are connected via a second hinge 54 parallel to the horizontal beam 15. The second hinge 54 is located at a position covering the upper surface 13a of the open space S, so that the first cover body 52 is configured to be rotatable to the back side of the second cover body 53 via the second hinge 54. Therefore, the angle members attached to the back sides of the first cover body 52 and the second cover body 53 are attached so as not to interfere with each other when folded. The second cover body 53 is formed in an L-shape in a side view so as to cover a part of the upper surface 13a and the side surface 13b perpendicular thereto, and further, the vertical plate 53b in Fig. 2 covering the side surface 13b is attached to the horizontal beam 15 via the hinge 51.

[0026] Therefore, as shown in Fig. 3, the second cover body 53 rotates in the direction of arrow F around the hinge 51 attached horizontally to the horizontal beam 15, and accompanying this rotation, the first cover body 52 rotates around the second hinge 54 toward the back surface side of the second cover body 53. As a result, as shown in Fig. 4, the first cover body 52 folds in half so as to cover the second cover body 53, and hangs down toward the horizontal beam 15. Note that handles 55 are provided on the upper surface of the second cover body 53 at positions spaced apart from each other on the left and right.

[0027] In this way, the cover 50 can be retreated in a folded state toward the horizontal beam 15 side, so that the open space S can be opened widely, and the lower chute 41 and the like can be easily attached and detached.

[0028] Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications are possible within the scope of the claims. For example, the first cover body 52 may be shaped to cover the entire upper surface 13a of the open space S, and the second cover body 53 may be shaped to cover the side surface 13b parallel to the horizontal beam 15, and the two may be connected by a second hinge 54, and a hinge 51 may be attached between the right edge or left edge of the first cover body 52 and the upper surface 10a of the base 10, so that the entire cover 50 can be rotated to the right or left.

[0029] Alternatively, the first cover body 52 and the second cover body 53 may be divided in half at a distance of 1 / 2 in the left-right direction, and hinges 51 may be attached to the left and right edges of each of the two halves of the right-side first cover body 52 and the left-side first cover body 52, so that the left and right covers 50 are configured in a double-door style that allows them to rotate left and right.

[0030] In any case, the opening 13 can be easily opened and closed, and even when the cover 50 is opened to expose the open space S, the cover 50 can be retreated to a position that does not interfere with cleaning or maintenance work. [Explanation of symbols]
