JP-A-2009-92399

In the combination weighing device as described above, a discharge chute for further discharging the articles discharged from the timing hopper may be provided below the timing hopper. In such a case, if the discharge chute is arranged away from the timing hopper so that the discharge chute can be easily attached and detached, the appropriate discharge of the article is hindered, such as spilling of the article between the timing hopper and the discharge chute. There is a risk. On the other hand, if the discharge chute is placed close to the timing hopper so that the article can be properly discharged from the discharge chute, the timing hopper becomes an obstacle when the discharge chute is attached / detached, which facilitates the attachment / detachment of the discharge chute. It may be hindered.

Therefore, an object of the present invention is to provide a combination weighing device in which a discharge chute can be easily attached and detached and an article is appropriately discharged from the discharge chute.

The combination weighing device of the present invention has a timing hopper that temporarily stores articles that are weighed and supplied at a plurality of locations, a discharge chute that further discharges articles discharged from the timing hopper, and a support that supports the discharge chute. And a wall member attached to the support, the discharge chute has a tubular chute body and is removable from one side in the first direction intersecting the vertical direction with respect to the support. Yes, the upper end of the chute body includes a first portion on one side in the first direction and a second portion on the other side in the first direction, the height of the second portion being the first portion. The first portion faces the lower end of the timing hopper in the first direction, and the wall member faces the lower end of the timing hopper in the first direction along the second portion.

In this combination weighing device, the discharge chute can be attached to and detached from one side in the first direction intersecting the vertical direction with respect to the support, and at the upper end of the chute main body portion, the second side on the other side in the first direction. The height of the two parts is lower than the height of the first part on one side in the first direction. As a result, physical interference between the lower end of the timing hopper and the upper end of the chute body is less likely to occur when the discharge chute is attached or detached. Further, in the state where the discharge chute is attached to the support, the first portion of the chute main body portion faces the lower end portion of the timing hopper in the first direction, and the wall member is along the second portion of the chute main body portion. In this state, it faces the lower end of the timing hopper in the first direction. This makes it difficult for articles to spill between the timing hopper and the discharge chute. Therefore, according to this combination weighing device, the discharge chute can be easily attached and detached, and the article is appropriately discharged from the discharge chute.

In the combination weighing device of the present invention, the second portion does not have to overlap with the lower end portion of the timing hopper when viewed from the first direction. As a result, physical interference between the lower end of the timing hopper and the upper end of the chute main body is less likely to occur when the discharge chute is attached or detached. Therefore, the discharge chute can be attached and detached more easily.

In the combined weighing device of the present invention, the upper end portion of the chute body portion further includes a third portion on one side in the second direction intersecting both the vertical direction and the first direction, and the height of the third portion is Lower than the height of the first portion, the timing hopper has a tubular hopper main body and a gate that opens and closes with respect to the lower opening of the hopper main body, and the gate has a first gate tip. It may be opened so as to pass between the portion and the wall member and approach the third portion. Since the height of the third portion is lower than the height of the first portion at the upper end portion of the chute main body portion, the weight of the discharge chute can be reduced, and as a result, the discharge chute can be attached and detached more easily. Further, since the gate opens so that the tip end portion of the gate passes between the first portion of the chute main body portion and the wall member and approaches the third portion of the chute main body portion, the gate and the third portion of the chute main body portion are connected. It is possible to prevent articles from spilling from between.

In the combined weighing device of the present invention, the support has a pair of support members extending to one side in the first direction, and the discharge chute has a chute body portion arranged between the pair of support members. It may further have a mounting portion that is mounted on a pair of support members in the state of being. As a result, by sliding the mounting portion of the discharge chute along the first direction on the pair of support members, physical interference between the lower end portion of the timing hopper and the upper end portion of the chute main body is suppressed while suppressing physical interference. The discharge chute can be easily attached and detached.

According to the present invention, it is possible to provide a combination weighing device in which the discharge chute can be easily attached and detached and the article is appropriately discharged from the discharge chute.

[Action and effect]

In the combination weighing device 1, the discharge chute 12A is removable from the A side to the support 18, and the height of the second portion 122b on the B side is the first on the A side at the upper end portion 122 of the chute main body portion 121. It is lower than the height of the portion 122a. As a result, when the discharge chute 12A is attached or detached, physical interference between the lower end portion 11a of the separate timing hopper 11A and the upper end portion 122 of the chute main body 121 is less likely to occur. Similarly, with respect to the separate timing hopper 11B and the discharge chute 12B, physical interference between the lower end portion 11a of the separate timing hopper 11B and the upper end portion 122 of the chute main body 121 is less likely to occur when the discharge chute 12B is attached or detached. Further, in the state where the discharge chute 12A is attached to the support 18, the first portion 122a of the chute main body 121 faces the lower end 11a of the separate timing hopper 11A in the X-axis direction, and the wall member 19 is the chute main body. Along the second portion 122b of the portion 121, it faces the lower end portion 11a of the separate timing hopper 11A in the X-axis direction. As a result, the article is less likely to spill between the separate timing hopper 11A and the discharge chute 12A. Similarly, for the separate timing hopper 11B and the discharge chute 12B, articles are less likely to spill between the separate timing hopper 11B and the discharge chute 12B. Therefore, according to the combination weighing device 1, the discharge chutes 12A and 12B can be easily attached and detached, and the articles are appropriately discharged from the discharge chutes 12A and 12B.

Further, in the combination weighing device 1, the second portion 122b of the chute main body portion 121 of the discharge chute 12A does not overlap with the lower end portion 11a of the separate timing hopper 11A when viewed from the X-axis direction. As a result, when the discharge chute 12A is attached or detached, physical interference between the lower end portion 11a of the separate timing hopper 11A and the upper end portion 122 of the chute main body 121 is less likely to occur. Similarly, for the separate timing hopper 11B and the discharge chute 12B, physical interference between the lower end portion 11a of the separate timing hopper 11B and the upper end portion 122 of the chute main body 121 is less likely to occur when the discharge chute 12B is attached or detached. Become. Therefore, the discharge chutes 12A and 12B can be attached and detached more easily.

Further, in the combination weighing device 1, the height of each third portion 122c is lower than the height of the first portion 122a at the upper end portion 122 of the chute main body portion 121 of the discharge chute 12A. As a result, the weight of the discharge chute 12A can be reduced, and as a result, the discharge chute 12A can be attached and detached more easily. Similarly, for the separate timing hopper 11B and the discharge chute 12B, the weight of the discharge chute 12B can be reduced, and as a result, the discharge chute 12B can be attached and detached more easily. Further, in the separate timing hopper 11A and the discharge chute 12A, the gate 113 is opened so that the tip portion 113a of the gate 113 passes between the first portion 122a and the wall member 19 and approaches the third portion 122c on one side. The gate 114 opens so that the tip 114a of the gate 114 passes between the first portion 122a and the wall member 19 and approaches the third portion 122c on the other side. As a result, in the separate timing hopper 11A and the discharge chute 12A, between the gate 113 and the third portion 122c on one side of the chute main body 121, and between the gate 114 and the third portion 122c on the other side of the chute main body 121. It is possible to prevent the article from spilling from between. Similarly, for the separate timing hopper 11B and the discharge chute 12B, between the gate 113 and the third portion 122c on one side of the chute main body 121, and between the gate 114 and the third portion 122c on the other side of the chute main body 121. It is possible to prevent the article from spilling from between.

Further, in the combination weighing device 1, a pair of attachment portions 123 of the discharge chute 12A are arranged in a state where the chute main body portion 121 of the discharge chute 12A is arranged between the pair of support members 183 extending on the A side. It is placed on the support member 183. As a result, as shown in FIGS. 7A and 7B, the attachment portion 123 of the discharge chute 12A is slid along the X-axis direction on the pair of support members 183, thereby causing the separate timing hopper 11A. The discharge chute 12A can be easily attached and detached while suppressing physical interference between the lower end portion 11a of the above and the upper end portion 122 of the chute main body 121. Similarly, for the separate timing hopper 11B and the discharge chute 12B, by sliding the attachment portion 123 of the discharge chute 12B along the X-axis direction on the pair of support members 184, the lower end portion 11a and the chute of the separate timing hopper 11B are formed. The discharge chute 12B can be easily attached and detached while suppressing physical interference with the upper end portion 122 of the main body portion 121.

Here, the effect produced by the discharge chute 12A will be described by exemplifying the discharge chute of the comparative example. As shown in FIG. 8, the discharge chute 221 of the comparative example is arranged to be separated from the separate timing hopper 11A to the lower side as compared with the discharge chute 12A. Therefore, the discharge chute 221 can be easily attached and detached while suppressing physical interference between the separate timing hopper 11 and the discharge chute 211. However, in the discharge chute 221 of the comparative example, there is a possibility that an article may spill between the separate timing hopper 11A and the discharge chute 221. Therefore, it is conceivable to increase the upper opening 221a of the discharge chute 221. However, the size of the lower opening 221b of the discharge chute 221 must be adjusted to the bag making and packaging machine 100, and the inclination angle of the inner surface of the discharge chute 221 must also be maintained for smooth sliding of the article. It doesn't become. Therefore, if the upper opening 221a of the discharge chute 221 is increased, the height of the discharge chute 221 must be increased. As described above, the use of the discharge chute 221 of the comparative example prevents the combined weighing device from being lowered in height. On the other hand, according to the discharge chute 12A, the height of the combination measuring device 1 can be reduced while facilitating the attachment / detachment of the discharge chute 12A and optimizing the discharge of articles.
