Description

  The present invention relates to a wall member that drops an article by being collided with an adhesive article and a weighing device including the wall member.

  In general, it is desirable to perform combination weighing in order to measure articles at high speed and with high accuracy. In combination weighing, the weights of articles contained in multiple hoppers are weighed for each hopper, and a combination calculation is performed based on these weight values to determine a combination of weight values so that the total value falls within a predetermined range. Then, the articles in the hopper corresponding to the combination are assembled. Thereby, the aggregate | assembly of articles | goods of predetermined weight or predetermined quantity can be obtained.

  As an apparatus for performing such combination weighing, there is one described in Patent Document 1, and an example thereof is shown in FIG.

  A combination weighing device 101 shown in FIG. 1 includes a table 102, a supply feeder 103, a pool hopper 104, a weighing hopper 105, a booster hopper 106, a horizontal conveyor 107, and the like. Here, the worker puts an appropriate amount of articles stocked on the table 102 into the supply feeder 103 in an appropriate amount via the loading port provided on the table 102. The articles put into the supply feeder 103 are supplied to the weighing hopper 105 through the pool hopper 104, the weight value is measured in the weighing hopper 105, and then supplied to the booster hopper 106. The control unit performs a combination calculation based on the weight values of articles stored in the weighing hopper 105 and the booster hopper 106. When a combination of weight values is selected as a result of the combination calculation, the gates of the corresponding hoppers 105 and 106 are opened, and the articles in the hoppers 105 and 106 are discharged onto the horizontal conveyor 107. The articles discharged onto the horizontal conveyor 107 are conveyed to either of the collective discharge chutes 110 and 120 and are collected when passing through the collective discharge chutes 110 and 120.

  The collective discharge chutes 110 and 120 have metal side walls forming a vertical surface or an inclined surface, and openings are formed at the upper and lower portions thereof. Articles put into the upper opening from the horizontal conveyor 107 are guided to the side wall, collected in the lower opening, and discharged. The collective discharge chute in other weighing devices has a generally similar structure.

  By the way, when the article is strongly struck against the side wall of the collective discharge chute, such as when the conveying speed of the horizontal conveyor is high, the article is placed on the side wall even if the side wall has a vertical or nearly vertical inclination. May adhere. In particular, in the case of an article having high adhesiveness, such an adhesion phenomenon is likely to occur. This phenomenon is also observed in foods such as pickles, but in the case of foods with extremely high tackiness such as kelp, spaghetti containing meat sauce, and salad containing mayonnaise, the article grows greatly on the wall. Then, the article that has become a large lump on the wall surface is peeled off from the wall surface at once. For this reason, there is a difference between the weight of articles collectively introduced into the collective discharge chute and the weight of articles delivered collectively from the collective discharge chute, making it difficult to control the amount of articles passing through the collective discharge chute. Become.

Therefore, in Patent Document 1, the side wall of the collective discharge chute is formed by a belt conveyor. This makes it difficult for the article to grow on the wall surface, and the article introduced into the collective discharge chute is smoothly discharged downstream.
JP 2002-173210 A

  However, when installing a belt conveyor like patent document 1, we are anxious about cost becoming high.

  An object of the present invention is to provide a wall member capable of conveying an adhesive article by a predetermined amount without preparing a complicated mechanism such as a belt conveyor, and a weighing device including the wall member.

  The wall member according to the first aspect of the present invention includes a first surface and a second surface, is disposed on the downstream side of the transport device, and drops the article by being collided with the article that has passed through the transport device. The conveying device conveys an adhesive article in a predetermined conveying direction. The first surface collides with and adheres to the article. The second surface collides with and adheres to the article. The first surface and the second surface are displaced in the horizontal direction so that the article attached to the first surface and the article attached to the second surface are not integrated.

  The wall member forms a wall surface that guides an adhesive article such as kelp conveyed by the conveying device downward by collision with the article. This wall member has at least two steps. Therefore, the area of the surface of each step is suppressed to be smaller than the area of the entire wall surface formed by this wall member. As a result, the article that collides with and adheres to the wall member peels off from the wall member little by little before growing into a large lump. Thereby, the adhesive article can be conveyed by a predetermined amount without preparing a complicated mechanism such as a belt conveyor.

  The wall member according to the second invention is the wall member according to the first invention, and the article attached to the first surface and the article attached to the second surface are peeled down separately.

  A large amount of articles are not peeled off at the same timing from the stepped wall member.

  The wall member according to the third invention is the wall member according to the first invention or the second invention, and the first surface is located above the second surface. The surface including the first surface is located upstream in the transport direction from the surface including the second surface.

  The wall member has a downward staircase shape along the article conveyance path. Therefore, it is difficult to store articles in the space between the steps. This makes it difficult for large lumps of articles to grow.

  A wall member according to a fourth invention is the wall member according to the third invention, further comprising a third surface. The third surface collides with and adheres to the article. The second surface is located above the third surface. The surface including the second surface is located on the upstream side in the transport direction with respect to the surface including the third surface.

  This wall member has at least three steps. Therefore, the area of the surface of each step is suppressed to be smaller than the area of the entire wall surface formed by the wall member.

  A wall member according to a fifth aspect is the wall member according to the third aspect or the fourth aspect, wherein the first surface and the second surface are discontinuous.

  Each surface of the wall member formed in a step shape is divided from each other. This makes it more difficult for articles to be stored in the space between the steps. Further, since the wall member has a downward staircase shape, the article to be conveyed does not face the gap between the steps and does not jump out of the conveyance path from the gap between the steps.

  A wall member according to a sixth aspect of the present invention is the wall member according to any one of the first to fifth aspects of the present invention, and the conveying device is disposed on the downstream side of the weighing device. The weighing device is a device that weighs an article and sends out the article by a predetermined amount.

  An article weighing device is arranged further upstream of the conveying device on the upstream side of the wall member. Therefore, this wall member can send the articles sent out by a predetermined amount after weighing in the weighing device to the downstream side with almost no error.

  A wall member according to a seventh aspect is the wall member according to any one of the first to sixth aspects, wherein the conveying direction of the conveying device is a substantially horizontal direction.

  An article collides with this wall member from the upstream side in a substantially horizontal direction. As a result, the wall member can guide the article traveling in a substantially horizontal direction downward.

  A weighing device according to an eighth aspect of the present invention includes a weighing unit, a transport unit, and a wall member, and measures an adhesive article. The weighing unit weighs the article and sends out the article by a predetermined amount. The transport unit transports the articles sent from the weighing unit in a predetermined transport direction by a predetermined amount. A wall member is arrange | positioned in the downstream of a conveyance part, and makes an article fall by colliding with the article which passed the conveyance part. The wall member has a first surface and a second surface. The first surface collides with and adheres to the article. The second surface collides with and adheres to the article. The first surface and the second surface are displaced in the horizontal direction so that the article attached to the first surface and the article attached to the second surface are not integrated.

  In this weighing device, an adhesive article such as kelp is weighed by the weighing unit and then sent to the conveying unit by a predetermined amount. Then, the article conveyed in a predetermined direction by the conveyance unit is guided downward by the collision with the wall member. This wall member has at least two steps. Therefore, the area of the surface of each step is suppressed to be smaller than the area of the entire wall surface formed by this wall member. As a result, the article that collides with and adheres to the wall member peels off from the wall member little by little before growing into a large lump. Thereby, the adhesive article can be conveyed by a predetermined amount without preparing a complicated mechanism such as a belt conveyor.

  In the present invention, an adhesive article can be conveyed by a predetermined amount without preparing a complicated mechanism such as a belt conveyor.

  Hereinafter, a combination weighing device 1 according to an embodiment of the present invention will be described with reference to the drawings.

<Configuration of combination weighing device 1>
The combination weighing apparatus 1 shown in FIG. 2 and FIG. 3 distributes articles such as foods into 10 weighing hoppers 5 and 10 booster hoppers 6 and adds them together based on the weight values of the articles in the hoppers 5 and 6. This is an apparatus for determining a combination of weight values so that values fall within a predetermined range, and collecting articles in the hoppers 5 and 6 corresponding to the combination to obtain a set of articles of a predetermined weight or a predetermined quantity.

The ten supply feeders 3, the pool hopper 4, the weighing hopper 5, and the booster hopper 6 correspond to each other on a one-to-one basis. That is, a product discharged from a certain supply feeder 3 is guided to a horizontal conveyor 7 via a specific pool hopper 4, a specific weighing hopper 5 and a specific booster hopper 6.

〔table〕
The table 2 is a rectangular tray capable of stocking articles. In the front portion of the bottom surface of the table 2, a plurality of input ports are opened at equal intervals. Below these input ports, a plurality of supply feeders 3 corresponding to these input ports in a one-to-one relationship are arranged in a straight line in the horizontal direction. Articles on the table 2 are put into the supply feeders 3 through these inlets.

[Supply feeder]
Each supply feeder 3 has an electromagnetic vibration device and an inclined trough. This electromagnetic vibration device applies vibrations to the articles put into the rear part of the inclined trough from the table 2 and conveys the articles to the pool hopper 4.

[Pool hopper, weighing hopper and booster hopper]
The pool hopper 4 is disposed below the front portion of the supply feeder 3 and receives and temporarily stores articles supplied from the supply feeder 3.

  The weighing hopper 5 is disposed directly below the pool hopper 4 and receives and temporarily stores articles discharged from the pool hopper 4. During this time, the weight value of the articles in each weighing hopper 5 is measured by the load cell 5a (see FIG. 3) in the drive box 8. The measured weight value is sent to a control unit (not shown) and used for the combination calculation.

  The booster hopper 6 is disposed directly below the weighing hopper 5 and receives and temporarily stores articles discharged from the weighing hopper 5. The articles stored in the booster hopper 6 participate in the combination calculation together with the articles in the weighing hopper 5.

  The structures of the pool hopper 4, the weighing hopper 5, and the booster hopper 6 are substantially the same. Each of the hoppers 4, 5, and 6 has a cylindrical main body that is formed of a synthetic resin and communicates with the upper and lower sides, and a gate that can open and close the lower opening of the main body. Each of the hoppers 4, 5, and 6 can store articles therein when the gate is closed, and can discharge the articles inside the gate when the gate is opened.

[Horizontal conveyor]
As shown in FIG. 4 and FIG. 5, the two horizontal conveyors 7 are belt conveyors each having a belt 7a, and convey articles discharged from the weighing hopper 5 and the booster hopper 6 in the horizontal direction. One horizontal conveyor 7 transfers the articles to the first collective discharge chute 10, and the other horizontal conveyor 7 transfers the articles to the second collective discharge chute 20. On both sides of the belt 7a on the conveyance surface, guide plates 7b are provided for guiding articles to be conveyed so as not to drop off from the conveyance surface.

[First collective discharge chute]
The funnel-shaped first collective discharge chute 10 is provided between the left and right horizontal conveyors 7 as shown in FIG. 2, so that articles falling from the inner end of the horizontal conveyor 7 are not scattered around. Lead down. The first collective discharge chute 10 uses the drop of the article due to gravity to discharge the article from the lower opening.

[Second set discharge chute]
As shown in FIGS. 4, 5, and 6, the second collective discharge chute 20 includes a first side wall 21, a second side wall 22, a third side wall 23, a fourth side wall 24, and a roof 25. Openings 30a and 30b are formed in the upper part. In FIG. 4, the third side wall 23 is omitted for easy understanding of the structure of the first side wall 21. The second collective discharge chute 20 receives an article through the upper opening 30a, passes the article through a space surrounded by the side walls 21 to 24 and the roof 25, and discharges the article through the lower opening 30b. A tray T is set by a separate device below the opening 30b, and articles discharged from the opening 30b enter the tray T. Further, the second collective discharge chute 20 is made of metal and is embossed although not clearly shown in the drawing.

  The first side wall 21 is composed of five rectangular plates 21 a to 21 e, and the width of each plate 21 a to 21 e is substantially equal to the width of the belt 7 a of the horizontal conveyor 7. Each of the plates 21a to 21e extends in the vertical direction, and faces in a direction facing the article conveyed to the upper opening 30a by the horizontal conveyor 7, and as a result, is collided with the article. Become. The plates 21a to 21e are arranged in this order in the vertical direction, with the plate 21a positioned at the uppermost position and the plate 21e positioned at the lowermost position. Projection line segments on the vertical lines of the plates 21a to 21e are continuous and do not overlap each other.

  Further, the plates 21a to 21e are arranged at equal intervals in the horizontal direction in this order, the plate 21a is located closest to the horizontal conveyor 7, and the plate 21e is located farthest from the horizontal conveyor 7. That is, the plates 21a to 21e are arranged so as to be shifted from each other in the horizontal direction, and the surfaces Sa to Se (see the two-dot chain lines in FIG. 4) including the plates 21a to 21e are conveyed in this order. It is located on the upstream side in the going direction.

  The plates 21 a to 21 e have discontinuous vertical sides, and the horizontal sides are continuous with the third side wall 23 and the fourth side wall 24. That is, a gap is widened between the lower side of the plate 21a and the upper side of the plate 21b, and the same applies to the other adjacent plates.

  The second side wall 22 is composed of one rectangular plate, and the width of the second side wall 22 is substantially equal to the width of the first side wall 21. The second side wall 22 faces the first side wall 21, but is lower in height than the first side wall 21. For this reason, an opening 70 a is formed between the roof 25 and the second side wall 22.

  The third side wall 23 and the fourth side wall 24 are each constituted by a single trapezoidal plate. The third side wall 23 and the fourth side wall 24 face each other, and are disposed so as to be orthogonal to both the first side wall 21 and the second side wall 22, respectively. The lower side of the third side wall and the fourth side wall 24 extends in the horizontal direction. Of the two sides extending in the vertical direction of each of the third side wall and the fourth side wall 24, the side closer to the horizontal conveyor 7 is longer than the side farther from the horizontal conveyor 7. As a result, the upper sides of the third side wall and the fourth side wall 24 are inclined downward toward the side farther from the side closer to the horizontal conveyor 7.

  The roof 25 is composed of a single rectangular plate, and is continuous with the upper side extending in the horizontal direction of the plate 31 a of the first side wall 21 and the inclined upper side of the third side wall 23 and the fourth side wall 24. Yes.

[Drive box, control panel]
The electromagnetic vibration device of the supply feeder 3, the drive motor for opening and closing the gates of the hoppers 4, 5, 6, the drive motor of the horizontal conveyor 7, the load cell 5 a of the weighing hopper 5, etc. are arranged in the drive box 8. . A column supporting the control panel 9 is fixed to the side of the drive box 8 (see FIG. 2).

  A control unit (not shown) including a CPU, a ROM, a RAM, an HDD, and the like is disposed on the back side of the control panel 9 or in the drive box 8. This control unit is connected to the above-described electromagnetic vibration device, drive motor, load cell 5a, and the like, and controls the operation of the combination weighing device 1. For example, the control unit performs a combination calculation based on measurement data sent from the load cell 5a. As a result of the combination operation, several hoppers 5 and 6 are selected from the ten weighing hoppers 5 and the ten booster hoppers 6. The combination calculation refers to obtaining a combination of articles such that the weight values of articles stored in the hoppers 5 and 6 are combined in various combinations and the total value falls within a predetermined range. And this control part drops a predetermined amount of articles | goods on the horizontal conveyor 7 by controlling to open the gate corresponding to the hoppers 5 and 6 which have stored the articles | goods contained in the combination calculated | required by the combination calculation. Let

  The control panel 9 serves as an input unit that receives input from an operator and also serves as a display unit that performs various displays.

<Operation of combination weighing device>
Next, the operation of the combination weighing device 1 will be described.

  In the combination weighing device 1, five heads each including a pool hopper 4, a weighing hopper 5, and a booster hopper 6 arranged in a line in the vertical direction are arranged in the left-right direction (see FIG. 2). The combination weighing device 1 has various uses. For example, it is possible to use all 10 heads on the left and right sides for weighing one kind of article, and collect the articles that have passed through the heads with the first collective discharge chute 10, and each of the 5 heads on the left and right sides can be of different types. It is also possible to use this method for weighing items, gathering the left five heads with the second collective discharge chute 20 and gathering the right five heads with the first collective discharge chute 10 It is.

  Hereinafter, a method of weighing an article using the left five heads and discharging the weighed article from the second collective discharge chute 20 to the tray T will be described. In addition, foods with high tackiness such as kelp, spaghetti containing meat sauce, and salad containing mayonnaise are assumed as the objects to be weighed.

[Operation from loading of goods to combination weighing]
First, an operator standing behind the combination weighing device 1 puts an appropriate amount of articles stocked on the table 2 into the supply feeder 3 in an appropriate amount via an insertion port provided on the table 102. The article put into the supply feeder 3 is supplied from the supply feeder 3 to the corresponding pool hopper 4 by vibration by the electromagnetic vibration device.

  When there is no article in the weighing hopper 5 below the pool hopper 4, the gate of the pool hopper 4 is opened, and the article in the pool hopper 4 is discharged into the weighing hopper 5. The weight value of the article supplied to the weighing hopper 5 is detected by the load cell 5a and sent to the control unit.

  When there is no article in the booster hopper 6 below the weighing hopper 5, the gate of the weighing hopper 5 is opened after the weight value of the article is detected, and the article in the weighing hopper 5 is discharged into the booster hopper 6. . The empty weighing hopper 5 is replenished with articles from the pool hopper 4. The weight value of the replenished article is also detected by the load cell 5a and sent to the control unit. That is, the current weight value of the article in the weighing hopper 5 and the current weight value of the article in the booster hopper 6 are stored in the control unit in association with the corresponding hoppers 5 and 6.

  Such an operation is performed for each head. Each time the hoppers 5 and 6 discharge the articles and receive new articles from the upstream hoppers 4 and 5, the weight value associated with the hoppers 5 and 6 and stored in the control unit is also updated. It will be.

  And a control part performs combination calculation based on these weight values. That is, the control unit selects several hoppers 5 and 6 that are optimal combinations from the ten weighing hoppers 5 and the ten booster hoppers 6. However, in order to select the weighing hopper 5, the booster hopper 6 below the weighing hopper 5 also needs to be selected.

  When the combination of the hoppers 5 and 6 is selected, the control unit opens the gates of the corresponding hoppers 5 and 6 and drops the articles in the hoppers 5 and 6 onto the horizontal conveyor 7. In the hoppers 5 and 6 emptied by discharging the articles, the articles are replenished sequentially from the upstream hoppers 4 and 5.

  During the operation of the combination weighing device 1, the above operation is repeated at a predetermined interval. As a result, a predetermined amount of articles drop from the hoppers 5 and 6 onto the horizontal conveyor 7 at predetermined intervals and are sent out to the second collective discharge chute 20.

[Aggregating operations of articles discharged from multiple weighing hoppers and booster hoppers]
The articles discharged from the hoppers 5 and 6 onto the horizontal conveyor 7 are transferred to the second collective discharge chute 20 by the horizontal conveyor 7. In this usage, the articles are conveyed to the second collective discharge chute 20 when the weighing is properly completed, and conveyed to the first collective discharge chute 10 when the articles in the hoppers 5 and 6 are discarded due to an error or the like. Is done. That is, the transport direction of the horizontal conveyor 7 can be switched in a forward / reverse manner by the control unit.

  The article placed on the belt 7a of the horizontal conveyor 7 and carried to the second collective discharge chute 20 falls obliquely downward toward the first side wall 21 as shown by the arrow A in FIG. Enter the enclosed space. That is, the articles conveyed in the horizontal direction by the horizontal conveyor 7 jump out in the horizontal direction from the end of the horizontal conveyor 7 due to its inertia, and obtain a downward speed by receiving gravity. As a result, the plates 21a to 21e of the first side wall 21 collide with the article.

  Most of the articles that have collided with the plates 21a to 21e bounce back by receiving a reverse force from the plates 21a to 21e, or fall into the lower tray T along the plates 21a to 21e. Articles bounced off due to the collision with the plates 21a to 21e are reliably accommodated in the tray T without jumping out from the second collective discharge chute 20 due to the presence of the second side wall 22, the third side wall 23, and the fourth side wall. It has become. Note that another device (not shown) for setting the tray T below the second collective discharge chute 20 is synchronized with the combination weighing device 1, and articles discharged from the hoppers 5 and 6 (plates 21a to 21e at a time). A new tray T is set each time the material is stored in the tray T.

  On the other hand, the remaining part of the articles that have collided with the plates 21a to 21e does not immediately fall and adheres to the plates 21a to 21e. During the operation of the combination weighing device 1, the articles are successively carried into the second collective discharge chute 20, so that a mass of articles gradually grows on the surfaces of the plates 21 a to 21 e. Since the five plates 21a to 21e are arranged so as to be shifted in the horizontal direction, the lump of articles on the surface of each plate 21a to 21e grows separately without being integrated.

  Then, the lump of articles grown on the surface of each plate 21a to 21e is peeled off from the plates 21a to 21e by its own weight when it reaches a certain size, and enters the tray T through the opening 30b. go.

<Characteristics of the combination weighing device 1>
In the said embodiment, the 1st side wall 21 to which the articles | goods which jumped out of the horizontal conveyor 7 face is comprised from the five plates 21a-21e, and is stepped. Therefore, compared with the conventional example in which the part corresponding to the first side wall is composed of one plate, the article attached to the first side wall 21 is gradually peeled off from the first side wall 21, and the first side wall 21 The lump of article does not grow too large on the surface of 21. As a result, the amount of articles conveyed by a predetermined amount to the second collective discharge chute 20 through the combination weighing before and after the passage of the second collective discharge chute 20 by the articles that are gradually peeled off from the first side wall 21 little by little. It does not fluctuate greatly. For this reason, the amount of articles generally set as the target value in the combination weighing is accommodated in the tray T.

  Thus, even if the second collective discharge chute 20 is not provided with a complicated mechanism such as a belt conveyor as in Patent Document 1, the second collective discharge chute 20 can convey an adhesive article such as kelp by a predetermined amount. It has become.

  Moreover, the 1st side wall 21 is descending step shape along the direction in which articles | goods are conveyed. That is, articles are not caught and stored between the steps of the stairs. Therefore, the lump of articles is large and difficult to grow.

  Moreover, although the clearance gap has spread between the plates 21a-21e adjacent to the perpendicular direction, since the 1st side wall 21 is descending step shape, the articles | goods conveyed are outside the 2nd collective discharge chute 20 from the said clearance gap. Never jump out.

<Modification>
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. Further, the features of the respective modifications shown below can be arbitrarily combined.

(A)
A weighing device other than the combination weighing device 1 may be arranged on the upstream side of the second collective discharge chute 20. That is, it may not be a combination weighing device, and another type of combination weighing device such as a type in which the hopper is arranged in a circle may be arranged. Alternatively, the weighing device may not be arranged on the upstream side of the second collective discharge chute 20.

(B)
The horizontal conveyor 7 may be inclined.

(C)
As shown in FIG. 7, not only the first side wall 21 but also the other side walls 22 may be stepped. Moreover, as shown in FIG. 8, the 1st side wall 21 may be comprised from one plate, and the 2nd side wall 22 may be comprised from several plate.

  That is, any of the side walls 21 to 24 of the second collective discharge chute 20 may have a stepped shape, but considering the effect of the present invention, it is preferable to have a stepped shape centered on a surface that easily collides with an article.

(D)
As shown in FIGS. 9 and 10, the first side wall 21 may be inclined as a whole. In the example of FIG. 9, the first side wall 21 is such that the upper plate 21a is positioned farther from the horizontal conveyor 7 in the horizontal direction than the lower plate 21e. In the example of FIG. It is located closer to the horizontal conveyor 7 in the horizontal direction than the plate 21e. In the example of FIGS. 9 and 10 as well, since the first side wall 21 has a descending step shape along the direction in which the articles are conveyed, as in the above embodiment, the articles are in the second collective discharge chute 20. Never jump out.

(E)
As shown in FIG. 11, the vertical sides of the plates 21 a to 21 e of the first side wall 21 may be continuous with each other. That is, there is no gap between the plates 21a to 21e, and the adjacent plates 21a to 21e may be connected by other plates.

(F)
As shown in FIG. 12, the projection line segment to the vertical line of each plate 21a-21e of the 1st side wall 21 may mutually overlap.

(G)
The number of plates constituting the first side wall 21 is not limited to five as in the above-described embodiment, and may be an appropriate number (a plurality) in consideration of the overall length of the first side wall 21 and the like. However, the size of a single plate needs to be such that the mass of articles growing on the surface does not exceed an allowable range.

(H)
The horizontal cross section of the second collective discharge chute 20 does not have to be rectangular as in the above embodiment, and may be, for example, circular, elliptical, or semicircular. It may be. In this case, each plate 21a-21e of the 1st side wall 21 may be a curved board instead of a plane board like the said embodiment.

(I)
The side walls of the first collective discharge chute 10 may also be stepped like the second collective discharge chute 20.

(J)
In order to prevent the articles from adhering to the inner surface of the second collective discharge chute 20, the second collective discharge chute 20 may be subjected to a surface treatment other than embossing, such as a shaper process.

  The present invention has an effect that an adhesive article can be conveyed by a predetermined amount without preparing a complicated mechanism such as a belt conveyor, and the article is made to collide with the adhesive article. It is useful as a wall member to be dropped and a weighing device provided with the wall member.
