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. The present invention relates to a bucket conveyor type sorting machine that measures items using various measuring devices and selects items to be sorted 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 from Japanese Patent Publication No. 17013/1973 that a roberval mechanism is provided on one side of the lever of the balance, and a bucket (saucer) is cantilevered on that part by a single fulcrum pin (rotating shaft). When the objects to be sorted are to be discharged to the lower part of the bucket transport path of the bucket conveyor, a system is known in which the bucket (receiving tray) is caused to sink and overturn, as disclosed in the above-mentioned Japanese Patent Publication No. 17013/1983.

[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.

The present invention eliminates the above-mentioned drawbacks and provides a bucket conveyor type sorting machine that can tilt a tray for placing objects to be sorted to either the left or right and discharge objects to be sorted to either the left or the right. The purpose is to

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

That is, the present invention provides a bucket for a bucket conveyor type sorting machine, in which two pins are provided in the lower part of a tray on which objects to be sorted are placed, parallel to the direction of travel at a predetermined distance from the left and right. At the top of the saucer support base,
Each of the pins is removable, and a pin receiving part is provided which holds the saucer horizontally when the two pins are received, and a pin receiving part is provided inside the saucer support base to connect the pins individually through a connecting member. Two connected movable members are provided so as to be able to move laterally, and a biasing means is provided to bias each movable member in the direction of separation and press each movable member against the left and right inner walls of the saucer support, respectively. When one of the two moving members is moved laterally against the force, the receiving tray is tilted to either the left or right. This is a bucket conveyor type sorting machine with a bucket configuration.
The tray for placing the items to be sorted can be tilted to either the left or right, and the items to be sorted can be discharged to either the left or right, and the tray can be stably held horizontally in the bucket itself, so that the tray can be held horizontally. It is possible to omit a stable receiving rail (guide rail) that serves as a support for stably holding and moving the object, and because of this omission, the discharge point is not fixed, and the receiving tray can be tilted at a desired point, making it possible to collect the objects to be sorted. It is designed to be able to be discharged.

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

The biasing force of the spring 7 that biases both sliders 5 in the lateral direction acts to draw each pin 2 into the pin receiving portion 4 and receive it through the connecting fitting 9 and the connecting rod 10 of the slider 5. When both sliders 5 are laterally biased by the spring 7 and pressed against the left and right inner walls of the saucer support 3, both pins 2 are pulled into the pin receiver 4 and received, and the saucer 1 is designed to be stably held horizontally, and in this way, the bucket tote of the present invention is designed to be able to stably hold the saucer 1 horizontally in the bucket itself. On the other hand, by laterally moving one of the two sliders 5 against the biasing force of the spring 7, the pin 2 connected to this one slider 5 via the connecting rod 10 is moved upward from the pin receiving part 4. The tray 1 is tilted to either the left or right around the pin 2 which is connected to the other slider 5 via the connecting rod 10, and which of the two sliders 5 is to be moved laterally. Depending on the selection, the saucer 1 can be tilted to the left or right, and the saucer can be tilted to either the left or right.

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 which come into contact with an actuating pin 8 protruding downward from the tray support stand 3 are partially connected to the running path 13 of the bucket chain conveyor.
A discharging means is provided on each of the left and right sides (one of the left and right is omitted in FIG. 5), and as the bucket advances, one of the sliders 5 is moved horizontally against the biasing force of the spring 7. Move the saucer horizontally and gently tilt the saucer 1 to either the left or right.
The material to be sorted above can 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 3 has a vertical contact surface 3b on a part thereof, on which a roller 12b rotatably fitted to the connecting pin 12a of the chain 11 can come into contact. When the bucket cart slides on the weighing device 16, the bucket cart slides on the stay 1.
