Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention mainly involves transporting objects to be sorted, such as fruits and side dishes, one by one on a bucket, and during transport using a weight measuring device or a photoelectric shape measuring device. This invention relates to a bucket conveyor type sorting machine that measures items using various other measuring devices and sorts items based on the measurement results.

[Conventional technology] Conventionally, the bucket of this type of sorting machine discharges the materials on the bucket (saucer) from side to side.
A bucket with one fulcrum pin at the lower center of the bucket, commonly known as the Yajirobee method, is known from Japanese Utility Model Application Publication No. 53-90391, etc., and when the materials to be sorted are to be discharged only to either the left or right side, It is known in Japanese Patent Publication No. 17013/1973 that a roberval mechanism is installed on one side of a lever that is like a balance, and a bucket (saucer) is cantilevered on that part with a single fulcrum pin (rotation shaft). However, when the objects to be sorted are discharged to the lower part of the bucket transport path of a bucket conveyor, a system is known in which the bucket (receiving tray) is made to sink and overturn, as disclosed in the above-mentioned Japanese Patent Publication No. 45-17013.

[Problems to be Solved by the Invention] The above-mentioned conventional bucket carts all have the disadvantage of requiring a stable support rail (guide rail) as a support for stably holding the bucket (saucer) horizontally and running it. At the same time, in order to tilt the tray and discharge the sorted materials on the tray, the stable receiving rail (guide rail) at the discharge point is cut out or the shape is changed, so the tray is tilted. There was a drawback that the parts were fixed.

An object of the present invention is to provide a bucket conveyor-type sorting machine that eliminates the above-mentioned drawbacks in a bucket that tilts a tray for placing objects to be sorted only to either the left or the right. It is something.

[Means for Solving the Problems] In order to achieve the above object, the present invention takes the following technical means.

That is, in the bucket of a bucket conveyor type sorting machine, the present invention provides two pins parallel to the traveling direction at a predetermined interval on the left and right at the bottom of the tray on which the objects to be sorted are placed to support the tray. The saucer is rotatably fixed to the top of the stand by a pin on one side of the two pins, and the pin on the other side is removable and receives the pin on the other side. A pin receiving part is provided to hold the saucer horizontally when the saucer is in use, and a movable member connected to the pin on the other side via a connecting member is provided inside the saucer support base so as to be movable laterally, with respect to the movable member. A biasing means having a biasing force that biases in a lateral direction from the other side to the one side, and causing the pin on the other side to be received in the pin receiving portion by the biasing force, and the movable member is biased. of a bucket conveyor type sorting machine, wherein the tray tilts only to the left or right when the tray is moved laterally against the This type of bucket is configured as a bucket and the tray on which the items to be sorted are placed can be tilted only to the left or right. Stable support rail (guide rail) as a support for holding and running
Because of this omission, the discharge location is not fixed, and the tray can be tilted at a desired location to discharge the material to be sorted.

[Example] Hereinafter, figures showing examples of the present invention will be described. Each figure shows an embodiment of the present invention.

Reference numeral 1 denotes a saucer, and as shown in FIGS. 1 and 4, two pins 2 and 2' are attached to the lower part of the saucer 1 symmetrically and parallel to the traveling direction at a predetermined interval. . Reference numeral 3 designates a saucer support stand, on the top of which the saucer 1 is rotatably fixed at a normal position by two pins 2, 2' on one side, and on the other side. A pin receiving part 4 is provided which holds the saucer 1 horizontally when the pin 2 is removable and receives the pin 2 on the other side. A slider 5 as a moving member capable of horizontal movement is attached with a slider pin 6. The slider 5
is applied in the lateral direction from the other side to the one side (that is, in the lateral direction from the pin receiving part 4 side to the pivot side) by a spring 7 as a biasing means on the inner wall of the saucer support base 3.
It is urged and pressed. Further, the slider 5 has an operating pin 8 protruding below the saucer support 3 at its lower part, and the operating pin 8 is moved laterally (from the one side to the above) against the biasing force of the spring 7. By being pushed in the lateral direction (towards the other side), it moves horizontally in this lateral direction.
Further, the slider 5 has a connecting fitting 9 on its upper part.

10 is a connecting rod as a connecting member;
The pin 2 on the other side provided at the lower part of the slider 5 is connected to the connecting fitting 9 of the slider 5 provided inside the saucer support 3. A spring 7 that biases the slider 5 in the lateral direction from the other side to the one side.
The biasing force is between the connecting fitting 9 of the slider 5 and the connecting rod 1.
0 to pull the pin 2 on the other side into the pin receiving part 4 and receive it, and the slider 5 is laterally biased from the other side to the one side by the spring 7 and When pressed against the inner wall of the support base 3, the pin 2 is pulled into the pin receiver 4 and received, so that the saucer 1 is stably held horizontally.
The bucket tote of the present invention is designed to stably hold the saucer 1 horizontally in the bucket itself. On the other hand, by laterally moving the slider 5 from the one side to the other side against the biasing force of the spring 7, the slider 5 is moved through the connecting rod 10.
The pin 2 on the other side, which is connected to (Figure 6 shows the left one and the right one).

The bucket cart constructed as described above is assembled to the stay 12 attached to the chain 11 to form a bucket chain conveyor, which is used in a sorting machine.

A guide rail 14 and a discharge actuating device 15 are provided in a part of the traveling path 13 of the bucket chain conveyor, and the guide rail 14 is in contact with the actuating pin 8 protruding downward from the tray support 3.
As the bucket advances, the slider 5 is moved horizontally against the biasing force of the spring 7, and the tray 1 is gently tilted only to the left or right to remove the cover on the tray 1. This allows the sorted material to be naturally discharged.

In the present invention, when assembling the bucket to the stay 12, as shown in FIG. 1 and FIG.
In addition, the two stays 12 are provided with loose fitting holes 3a through which the two stays 12 pass in parallel in the lateral direction, so that the tray support 3 can be placed in a non-contact state with respect to the stays 12 in the front and rear, up and down directions. It is assembled loosely.
Further, as shown in FIGS. 2 and 3, the saucer support base 3 has a roller 12b rotatably fitted on a connecting pin 12a as a connecting fitting of the chain 11.
has a vertical contact surface 3b that can be brought into contact with the weighing device 12, and when the bucket cart slides on the weighing device 16, the bucket cart is in a non-contact state with the stay 12,
Only the roller 12b is in circumscribed contact with the vertical abutment surface 3b to move the bucket cart forward, and the bucket cart of the present invention can be used for weight sorting as well, allowing for highly accurate sorting. Furthermore, the present invention
As shown in FIGS. 1 and 4, the saucer support 3 has tapered portions 3c on both sides thereof, which slope downward symmetrically from left to right toward the center.
The bucket is centered. or,
In the bucket bag of the present invention, when the slider 5 is not moved laterally against the biasing force of the spring 7,
In other words, since the slider 5 is pressed by the spring 7 in areas other than the part to be discharged, the pin 2 of the saucer 1 is pulled into the pin receiving part 4 by the connecting rod 10 connected to the slider 5, and the bucket travels. Even if the bucket is turned upside down on the return side of the road, the saucer 1 will not tilt.

[Operations and Effects of the Invention] As described above, the present invention provides two pins parallel to the traveling direction at a predetermined interval on the left and right at the bottom of the tray on which the objects to be sorted are placed, and two pins are provided in the upper part of the tray support. , The pin on one side of the two pins allows the saucer to be rotatably fixed at a fixed position, and the pin on the other side is removable, and when the pin on the other side is received, the saucer is held horizontally. A pin receiving portion is provided for holding the pin on the other side, and a movable member connected to the pin on the other side via a connecting member is provided inside the saucer support base so as to be movable laterally, and the moving member is moved from the other side to the one side with respect to the movable member. A biasing means is provided which has a biasing force that biases the pin in the lateral direction, and causes the pin on the other side to be received in the pin receiving part by the biasing force, and the movable member is moved laterally against the force. In this case, since the tray is a bucket of a bucket conveyor type sorting machine configured so that the tray can only be tilted to either the left or the right around the pin on the one side to which the tray is pivotally connected, the portion other than the area to be discharged is In this case, the pin connected to the moving member via the connecting member is pushed into the pin receiving portion by the urging force of the urging means that urges the moving member in the lateral direction from the other side to the one side. Since it is pulled in and received and the saucer is stably held horizontally, the bucket itself can stably hold the saucer horizontally, and the stable receiver rail (guide rail) for holding the saucer horizontally and stably while traveling is omitted. can,
Due to this omission, the discharge location is not fixed, and the tray can be tilted at a desired location to enable the material to be sorted to be discharged.

Further, the bucket tote of the present invention is a bucket tot that tilts the tray for placing the objects to be sorted only to either the left or the right, but as described above, it is a bucket tot that can stably hold the tray horizontally in the bucket itself. Therefore, even on the return side of the bucket running path, there is no need for a stable receiving rail (guide rail) as described above, and there is an effect that the receiving tray will not tilt even if the bucket is turned upside down.

In addition, in the present invention, when assembling the bucket to the stay attached to the chain, the saucer support is provided with a loose fitting hole so that the saucer support can be assembled in a loose fit manner so that the tray can be in a non-contact state with the stay. For example, the bucket can be placed in a non-contact state with the stay on the weighing device, and can also be used for weight sorting.
