Further, receptacles 115 and 125 are arranged directly below the weighing tanks 114 and 124, respectively. In addition, in the first weighing unit 11, a storage receiver 116a is disposed upstream of the receiver 115 (positive direction of the X axis), and a storage receiver 116a is disposed downstream of the receiver 115 (negative direction of the X axis). 116b are arranged. In the second metering unit 12 , a storage receiver 126 is arranged downstream of the receiver 125 .

Further, the first weighing unit 11 and the second weighing unit 12 incorporate a transport conveyor 2 for transporting the leek bundles received by the receivers 115 and 125 from the weighing tanks 114 and 124 to the binding device 20 .

A plurality of conveying members 201 are hung in parallel on these rotating rollers at predetermined intervals, thereby forming the conveyer 2 . The conveying member 201 consists of a narrow belt, a chain such as a plastic chain (for example, a plastic block chain), or a rope such as a round belt. , chains, or ropes. The conveying conveyor 2 has the upper surface of the conveying member 201 as a leek conveying surface, and is forcibly rotated by the conveying conveyor driving device 26 installed in the binding device 20 . In this embodiment, since the bundle of Chinese chives weighed by the weighing device 10 is conveyed to the binding device 20, hereinafter, the conveying source side (X-axis positive direction side) is the upstream side, and the conveying destination side (each X-axis negative direction side) will be described as the downstream side.

Next, the operation of the first weighing unit 11 will be described. FIG. 5 is a diagram for explaining the operation of the first weighing unit 11. FIG. First, when an operator puts a bundle of Chinese chives into the weighing tank 114 , the weighing machine 113 measures the weight of the chives put into the weighing tank 114 . As shown in FIG. 5, the weighing tank 114 includes a load cell 1141 and a pair of opening/closing cylinders 1143a and 1143b for opening and closing a bottom portion 1142. When the weighed value of the load cell 1141 reaches a specified amount, the receiver 115 rises. , opening and closing cylinders 1143a and 1143b open the bottom 1142, and the leek is delivered to the receiver 115.

As shown in FIG. 3 or FIG. 4, the receiver 115 is connected to a lift cylinder 117 and is configured to be liftable by the lift cylinder 117. As shown in FIG. The up-and-down motion of the receiver 115 is controlled by the control device 112, and when the receiver 115 receives the bundle of Chinese chives from the weighing tank 114, the receiver 115 rises, and the receiver 115 delivers the bundle of Chinese chives to the conveyor 2. In this case, the receiver 115 is controlled to descend. In this embodiment, the conveying members 201 are arranged with a predetermined gap on the conveying conveyor 2, and the receivers 115 move up and down above or below the conveying surface of the conveying conveyor 2 by passing through the gap. It is possible to

Here, FIG. 6A is a perspective view of the receiver 115 according to this embodiment, and FIG. 6B is a perspective view of a conventional receiver. The receiver 115 has a mounting portion 1151, an inclined portion 1152, and a damming portion 1153, as shown in FIG. 6(A). The placement portion 1151 is a portion on which the bundle of Chinese chives received from the weighing tank 114 is placed, and is formed substantially horizontally in this embodiment. In addition, the inclined portion 1152 is formed to be connected to the upstream end of the placing portion 1151, and the bundle of Chinese chives placed on the placing portion 1151 does not fall from the receiving portion 115. It is formed to be inclined so as to rise from the 1151 side toward the upstream side.

Furthermore, a damming portion 1153 is formed in the receiver 115 so as to be connected to the downstream end portion of the mounting portion 1151 . In the present embodiment, the damming portion 1153 is a portion that is formed to rise in a substantially vertical direction or substantially vertically, and is connected to the mounting portion 1151 at the lower end of the damming portion 1153 . Moreover, the damming portion 1153 is formed so that at least the upper end thereof protrudes upward from the conveying surface of the conveyer 2 when the receiver 115 descends to a retention position P3, which will be described later. It should be noted that the damming portion 1153 is not limited to a configuration that rises substantially vertically or substantially vertically, and may be configured to be inclined so as to become higher toward the downstream side. However, the damming portion 1153 is a member for damming the bundle of chives conveyed downstream by the conveying conveyor 2 when the receiver 115 descends to the retention position P3, and functions as such a damming member. In order to achieve the above, the inclination angle of the damming portion 1153 (the angle formed by the mounting portion 1151 and the damming portion 1153) is preferably 45° or more and 90° or less.

The control device 112 controls the lifting operation of the receiver 115 . Specifically, the receiver 115 is on standby at a standby position P1, and when the bundle of Chinese chives is delivered from the weighing tank 114 to the receiver 115, it rises to the receiving position P2 to receive the bundle of Chinese chives from the weighing tank 114. . In the present embodiment, the standby position P1 is a position below the conveying surface of the conveyer 2, and is a position where all of the damming portions 1153 of the receivers 115 are below the conveying surface of the conveyer 2. be done. When the receiver 115 receives the bundle of Chinese chives, the controller 112 lowers the receiver 115 from the receiving position P2 to the staying position P3. As shown in FIG. 5, the staying position P3 is a position where the bundle of chives is placed on the conveying surface of the conveying conveyor 2 and the damming portion 1153 of the receiver 115 protrudes above the conveying surface of the conveyer 2. be. When the controller 112 lowers the receiver 115 to the retention position P3, the leek bundle is placed on the conveying surface of the conveyor 2 and conveyed downstream, but is blocked by the damming portion 1153 of the receiver 115. As a result, the spread L1 of the leek bundle when the receiver 115 receives the leek bundle from the weighing vessel 114 as shown in FIG. , and the variation in bundles of Chinese chives can be reduced. FIG. 7 is a diagram for explaining the function of the receiver 115 according to this embodiment.

In particular, in the present embodiment, the control device 112 performs control to stop the receiver 115 at the retention position P3 for a predetermined retention time T1 after lowering the receiver 115 to the retention position P3. The residence time T1 is not particularly limited, but can be 100 ms to 1000 ms, preferably 300 ms to 500 ms. If the time is shorter than 100 ms, the variation in bundles of Chinese chives cannot be sufficiently reduced, and if it is longer than 1000 ms, a delay will occur in the continuous automatic weighing and bundling process of Chinese chives. Also, the residence time T1 can be appropriately changed according to the transport speed of the transport conveyor 2 . For example, when the transport speed of the transport conveyor 2 is fast, the residence time T1 can be shortened compared to when the transport speed is slow.

Further, the controller 112 performs control to lower the receiver 115 from the staying position P3 to the standby position P1 after the staying time T1 has passed. As a result, the bundle of Chinese chives blocked by the damming portion 1153 is conveyed downstream by the conveyor 2 and bound by the binding device 20 arranged downstream. When the bundle of Chinese chives is conveyed by the conveyer 2, the controller 112 causes the receiver 115 to wait at the standby position P1 until the next reception.

Further, when the control device 112 detects that there is a bundle of Chinese chives downstream of the receiver 115 by a sensor (not shown), the controller 112 temporarily stops the receiver 115 holding the bundle of Chinese chives at the storage position P4, and the receiver 115 holds the bundle of Chinese chives. It is possible to adjust the transfer interval between the bundle of Chinese chives on the conveyer 2 and another bundle of Chinese chives being conveyed on the downstream side of the conveyor 2 so as to be a constant interval. In this case, the control device 112 can determine the temporary stop time (retention time T2) at the retention position P4 in consideration of the retention time T1 for retaining the receiver 115 at the retention position P3. In addition, the control device 112, for example, in another weighing unit arranged downstream, when the bundle of Chinese chives is being transferred from the weighing tank 114 to the transport conveyor 2, or when the receiver 115 is holding To hold a bundle of Chinese chives even when the bundle of Chinese chives is handed over to a conveyer conveyor 2 immediately and the transfer interval with another bundle of Chinese chives conveyed on the downstream side of the conveyer conveyor 2 becomes short. It is also possible to adopt a configuration in which the receiver 115 is temporarily stopped at the storage position P4.
In the present embodiment, damming up the leek bundles conveyed by the conveyor 2 in order to suppress variations in the leek bundles is referred to as "staying", and the leek bundles are used to adjust the transfer interval of the leek bundles. Receiving and holding at 115 is referred to as "storage."

Further, in this embodiment, the control device 112 controls not only the receiver 115 but also the raising and lowering operations of the storage receivers 116a and 116b. The storage receivers 116a and 116b, like the receiver 115, are formed with a placing portion, an inclined portion, and a damming portion, and have a function of temporarily storing the leek bundle at the damming portion. As shown in FIGS. 3 and 4, the storage receivers 116a and 116b are connected to lifting cylinders 118a and 118b. can be raised and lowered. The standby position P5 of the storage receivers 116a and 116b can be positioned at the same height as the standby position P1 of the receiver 115. Positioning on the lower side enables the bundle of Chinese chives to be transported by the transport conveyor 2 . The retention position P6 can be set at the same height as the retention position P3 of the receiver 115, and a part of the damming portion of the retention receivers 116a and 116b projects above the conveying surface of the conveyor 2. This is the position where the bundle of Chinese chives conveyed on the conveyor 2 can be dammed and retained. Furthermore, the storage position P7 of the storage receivers 116a and 116b can be positioned at the same height as the storage position P4 of the receiver 115. FIG.

The control device 112 has information on where the receiver 115 is located, and when a sensor (not shown) detects that the leek has been transported from upstream when the receiver 115 is at the receiving position P2, the control device 112 moves to the standby position. The storage receiver 116a at P5 is raised to block the leek bundle at the storage receiver 116a, and then the storage receiver 116a is raised to the storage position P7 to store the leek bundle. In addition, the control device 112 monitors the processing status of the leeks in the binding device 20 with a sensor (not shown), and when the amount of leeks conveyed increases relative to the processing speed of the binding device 20, the storage receiver 116b scoops up the leeks. It is also possible to maintain a constant transfer interval by accumulating. When the bundles of Chinese chives stored in the storage receptacles 116a and 116b are to be returned to the conveyor 2, the control device 112 lowers the storage receptacles 116a and 116b from the storage position P7 to the retention position P6. By stopping at P6 for a predetermined staying time T1, after the variation in the leek bundle is reduced, the storage receivers 116a and 116b are lowered from the staying position P6 to the waiting position P5. As a result, the stored leek bundle is transferred to the conveying surface of the conveyer 2 and conveyed downstream.

The second weighing unit 12 also has a receiver 125 and a storage receiver 126 having the same structure as the receiver 115 of the first weighing unit 11 . , has a damming portion 1253 . Further, in the second weighing unit 12 , the receiver 125 and the storage receiver 126 are operated under the control of the control device 122 in the same manner as the first weighing unit 11 . Since the second weighing unit 12 is arranged on the most upstream side of the automatic weighing and bundling device 1 , it does not have a storage receiver upstream of the receiver 125 .

Next, the binding device 20 will be described. The binding device 20 includes a rectangular parallelepiped frame 21, an operation section 22, a binding machine 23, an upper rotating roller 24, and a lower rotating roller 25, as shown in FIGS. The operation unit 22 has a touch panel that displays the operation status of the weighing device 10 and the binding device 20, and is capable of monitoring the operation status of each device and inputting various parameters. The bundling machine 23 bundles bundles of Chinese chives conveyed in weighing units and binds them together. The binding machine 23 has a known positioning device. This positioning device is composed of an endless chain provided parallel to the conveying conveyor 2 and a positioning arm fixed to the endless chain for moving the chives on the conveying conveyor 2 to a positioning arm positioned downstream. By the operation of the positioning arm, a plurality of chives are formed into a substantially cylindrical shape in side view. The strapping machine 23 is a known strapping device with a packer, a strapping needle, a strapping holder and a knot making section consisting of a knotter bill, and a release (door). In the binding machine 23, when the chives of a predetermined weight are arranged at the binding position of the transport conveyor 2, the needle and the knot forming part are actuated to bind them with a rubber string or the like. When the chives are bound, the downstream passage is opened by raising the positioning arm.

As described above, in the automatic weighing and binding device 1 according to the present embodiment, the receiver 115 is provided with the damming portion 1153 for blocking and retaining the bundle of Chinese chives conveyed by the conveyor 2 for a certain period of time. , the receiver 115 is lowered from the receiving position P2 to the retention position P3, and is stopped at the retention position P3 for the retention time T1. A bundle of Chinese chives to be cooked is dammed by the damming portion 1153 of the receiver 115 . As a result, in the present embodiment, as shown in FIG. 7(A), even in bundles of chives with large variations, the damming part 1153 dams them, so that the variations in the bundles of chives as shown in FIG. 7(B) are reduced. can be made smaller. As a result, the leek bundle can be bound more reliably by the binding device 20 . In other words, although the binding device 20 can bind the materials if there is a predetermined variation, the binding device 20 may not be able to perform the binding if the variation exceeds a certain value. On the other hand, in the automatic weighing and binding device 1 according to the present embodiment, the variation in the leek bundles can be reduced before being conveyed to the binding device 20, so that the leek bundles in the binding device 20 can be more reliably bundled. It is possible to conclude. In addition, when a test was conducted using the automatic weighing and binding device 1 according to the present embodiment, the spread due to the variation in the bundle of Chinese chives when received by the receiver 115 (for example, L1 shown in FIG. 7 (A)) was It was confirmed that by damming the leek bundle at 1153, the spread could be reduced to about half (for example, L2 shown in FIG. 7(B)).

Although preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the description of the above embodiments. Various modifications and improvements can be added to the above-described embodiment examples, and forms with such modifications and improvements are also included in the technical scope of the present invention.

For example, in the above-described embodiment, when leek bundles are stored in order to adjust the transfer interval of the leek bundles, the control device 112 moves the receptacles 115, 125 or the storage receptacles 116a, 116b, 126 to the storage position P4. , P7 has been exemplified, but the configuration is not limited to this configuration, and the receivers 115, 125 or the storage receiver 116a can also be used to store bundles of Chinese chives in order to adjust the transfer interval of bundles of Chinese chives. , 116b and 126 may be temporarily stopped at the staying positions P3 and P6.

Further, in the above-described embodiment, the configuration in which the receiver 115 has the damming portion 1153 was exemplified, but the present invention is not limited to this configuration. For example, as shown in FIGS. A configuration having a damming member 119 independent of the receiver 115' is possible. For example, as shown in FIG. 8A, the damming member 119 is arranged above the conveyor 2, and the damming member 119 is lowered to the conveying surface of the conveyor 2. Alternatively, as shown in FIG. ), the damming member 119 is arranged below the conveying conveyor 2, and the damming member 119 is raised to the conveying surface of the conveying conveyor 2, thereby closing the conveying path of the conveying conveyor 2 with the damming member 119. A damming member 119 may be used to dam the bundle of Chinese chives transferred from the receiver 115 ′ to the conveyor 2 . Similarly, as shown in FIG. 8(C) or FIG. 8(D), the damming member 119 is arranged on the back side (Y-axis positive direction side) of the conveyer 2, and the damming member 119 is placed on the conveyor 2. By horizontally moving (sliding in the Y-axis negative direction) to the conveying surface of , or by arranging the damming member 119 on the front side (Y-axis negative direction side) of the conveying conveyor 2, the damming member 119 is conveyed. By horizontally moving (sliding in the Y-axis positive direction) to the conveying surface of the conveyor 2, the conveying path of the conveying conveyor 2 is blocked by the damming member 119, and the bundle of chives delivered from the receiver 115' to the conveying conveyor 2 is dammed. A configuration in which the member 119 is used as a dam is also possible. Furthermore, as shown in FIG. 9(A) or (B), the damming member 119 is pivotally supported so as to be rotatable upward or downward, and the damming member 119 is moved upward so as to block the conveying path of the conveyor 2. The damming member 119 may be configured to dam the bundle of Chinese chives transferred from the receiver 115' to the conveyer 2 by rotating it in the direction or downward. In addition, as shown in FIG. 9(C) or (D), the damming member 119 is horizontally rotatably pivotally supported, and the damming member 119 is moved horizontally so as to block the conveying surface of the conveyor 2. A configuration may be adopted in which the damming member 119 dams up the bundle of Chinese chives transferred from the receiver 115' to the conveying conveyor 2 by rotating it. In this way, the damming member 119 is provided downstream of the receiver 115' as a member independent of the receiver 115', and the damming member 119 is operated to close/open the conveying surface of the conveyor 2. Regardless of the shape of 115', it is possible to dam the bundle of chives, reduce variations in the bundle of chives, and convey the bundle of chives to the downstream binding device 20. In the case shown in FIGS. 8 and 9 as well, it is preferable that the damming member 119 stops the bundle of Chinese chives at that position for a predetermined staying time T1. The damming member 119 may be provided for each of the weighing units 11 and 12, or, for example, may be provided only one immediately before the binding device 20. FIG.

Moreover, even if a member such as the damming member 119 is not used, a damming portion 1153' having a certain degree of inclination angle is provided at the downstream end like the receptacle 115' shown in FIG. The damming portion 1153' of 115' stops for a predetermined staying time T1 at a staying position P3 projecting upward from the conveying surface of the conveying conveyor 2, thereby suppressing variations in the bundle of Chinese chives. Thus, if the receiver 115' has a damming portion 1153' having a height higher than the bottom surface 1151' on the downstream side of the position where the leek bundle is placed, the shape is particularly Not limited.

Furthermore, in the above-described embodiment, the configuration in which the transport conveyor 2 is formed from the weighing device 10 to the binding device 20 was illustrated, but the first weighing unit 11, the second weighing unit 12, and the binding device 20 are each a transport conveyor. , and the most upstream portion of each conveying conveyor may enter the most downstream portion of another conveying conveyor.

In addition, in the present embodiment, the configuration in which the mounting portion 1151 of the receiver 115 is substantially horizontal was exemplified. can also Further, as described above, the shape of the receiver 115 is not particularly limited as long as it forms a damming portion having a height higher than the placing portion 1151 on which the bundle of Chinese chives is placed. The whole can be formed in a V-shape or a U-shape, a U-shape rotated clockwise by 90 degrees, or a square-like shape.
