Abstract

PURPOSE:To obtain the flexibility of a discharging place in the present bucket for fruit, etc., by supporting a pan on a pan supporting base with two pins and laterally moving one pin to revolvingly incline the pan around the other pin. CONSTITUTION:One pin 2 of a pan 1 is kept drawn in the pin receiver 4 of a pan supporting base 3 by means of a slider 5 positioned on the left side in the figure by the energizing force of a spring 7 and a linking rod 10 linked to the slider 5 to keep the pan 1 in a horizontal posture. As the slider 5 is moved rightward in the figure, the pin 2 is pushed upward by the linking rod 10 and separated from the pin receiver 4 causing the pan 1 to be inclined around a pin 2'. By this structure, as an operating pin 8 is operated in a required discharging place to laterally move the slider 5, discharging can be carried out in an optional place obtaining flexibility in setting a discharging place.

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 in a bucket, and using a weight measuring device or a photoelectric shape measuring device during the transportation. The present invention relates to buckets of a bucket conveyor type sorting machine that measures objects using various measuring devices and sorts objects based on the measurement results.

[Conventional technology] Conventionally, the buckets of this type of sorting machine were buckets (saucers).
When discharging the upper selected objects from side to side, a bucket with a single fulcrum pin at the bottom center is known as a so-called Yajirobee method, as disclosed in Japanese Utility Model Application Publication No. 53-90391, etc.
When discharging objects to be sorted only to either the left or right side,
Japanese Patent Publication No. 17013/1974 has a donkey pal mechanism on one side of the stacking rod of the balance, and a bucket (saucer) at the core with one fulcrum pin (cantilevered around the rotation axis ρ). In the case of discharging objects to be sorted to the lower part of the bucket conveyance path of a bucket conveyor, the bucket (receiving tray) is caused to fall by sinking, as described in the above-mentioned Japanese Patent Publication No. 45-
It is publicly known from Publication No. 17013 and the like.

[Problems to be Solved by the Invention] All of the conventional buckets described above have the disadvantage that they require a stable receiving rail (guide rail) as a support to stably hold the packet (saucer) horizontally and run it. In addition, a stable receiving rail (guide rail) is installed at the discharge point in order to tilt the receiving tray and discharge the materials on the receiving tray.
Since the structure is such that the tray is tilted by cutting out or changing the shape, there is a drawback that the discharge point is fixed.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bucket for a bucket conveyor type sorting machine that eliminates the above-mentioned drawbacks in a bucket in which a tray for placing objects to be sorted is tilted to either the left or right. be.

[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 two wooden pins parallel to the direction of travel at a predetermined interval on the left and right at the bottom of a tray for placing objects to be sorted on the bucket of a bucket conveyor type sorting machine. The saucer is rotatably attached to the upper part of the support base by a pin on one side of the two pins, and the pin on the other side is detachable and receives the pin on the other side. and a pin receiver for holding the saucer horizontally, 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 is provided which has a biasing force that biases the pin on the other side in the pin receiving portion by the biasing force, and the movable member resists the force so as to cause the pin on the other side to be received in the pin receiving portion.
When the tray is moved, the tray is configured as a bucket of a bucket conveyor type sorter such that the tray tilts around the pin on one side to which the tray is pivotally connected, and the container is configured as a bucket of a bucket conveyor type sorter. A stable support rail for a bucket that tilts the tray to be placed only to either the left or right, which can stably hold the tray horizontally within the bucket itself, and serves as a support for traveling while stably holding the tray horizontally. (Guide rails) can be omitted, and because of this omission, the discharge location is not fixed, and the tray can be tilted at a desired location to discharge the materials to be sorted.

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

1 is a saucer, and as shown in FIGS. 1 and 4, the saucer 1
Two pins 2.2° are attached to the lower part of the vehicle 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 pivoted by two pins 2, 2' on one side, and the pin 2 on the other side. A pin receiving part 4 is provided which is removable and holds the saucer 1 horizontally when receiving the pin 2 on the other side. A slider 5 as a movable member is attached with a slider pin 6.

The slider 5 is laterally biased and pressed against the inner wall of the saucer support base 3 by a spring 7 serving as biasing means. Moreover, the slider 5 has a saucer support 3 at its lower part.
It has an operating pin 8 that projects downward, and when the operating pin 8 is pushed laterally against the biasing force of the spring 7, it moves horizontally in the lateral direction.

Further, the slider 5 has a connecting fitting 9 on its upper part.

1O is a connecting rod as a connecting member, which connects the pin 2 on the other side provided at the lower part of the saucer 1 and the connecting fitting 9 of the slider 5 provided inside the saucer support 3. The biasing force of the spring 7 applied laterally to the slider 5 acts through the connecting fitting 9 and the connecting rod 10 of the slider 5 to pull the pin 2 on the other side into the pin receiving part 4 and receive it. When the slider 5 is laterally biased by the spring 7 and pressed against the inner wall of the saucer support 3, the pin 2 is pulled into the pin receiver 4 and received, and the saucer 1 is stabilized horizontally. In this way, the bucket of the present invention can stably hold the saucer 1 horizontally in the bucket itself. On the other hand, by laterally moving the slider 5 against the biasing force of the spring 7, the pin 2 on the other side connected to the slider 5 via the connecting rod 10 is disengaged upward from the pin receiving part 4, and the pin 2 on the other side Center the pin 2° on the saucer 1.
can be tilted to either the left or the right (FIGS. 1 and 4 show the left one, and FIG. 6 shows the left and right ones).

The bucket 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 discharge means consisting of a guide rail 14 that comes into contact with the operating pin 8 protruding downward from the tray support 3 and a discharge actuator 15 is provided in a part of the travel path 13 of the bucket chain conveyor, and the slider 5 is moved as the bucket advances. spring 7
The object to be sorted on the tray 1 can be naturally discharged by moving the tray 1 horizontally against the urging force of the container 1 and gently tilting the tray 1 to either the left or the right.

In the present invention, in order to assemble the bucket to the stay 12, as shown in FIG. 1 and FIG. The saucer support 3 is loosely attached to the stay 12 so that it can be placed in a non-contact state in the front and rear, upper and lower directions with respect to the stay 12. In addition, the saucer support 3 has a part shown in FIG.
As shown in FIG. 3, it has a vertical contact surface 3b on which a roller 12b rotatably fitted onto a connecting pin 12a as a connecting fitting of the chain 11 can come into contact, and the bucket slides on the weighing device 16. Then, the bucket is on stay 12
The roller 12b is in a non-contact state with respect to the vertical contact surface 3b, and the bucket is advanced so that only the roller 12b is in circumscribed contact with the vertical contact surface 3b.The bucket of the present invention can be used for weight sorting with high accuracy. It is possible. Further, in 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. Furthermore, in the bucket of the present invention, when the slider 5 is not moved laterally against the biasing force of the spring 7, that is, when the slider 5 is not moved at a location other than where it should be ejected, the slider 5 is pressed by the spring 7, so that the slider 5 The pin 2 of the saucer 1 is connected by the connected connecting rod lO.
is drawn into the pin receiving part 4, and the receiving tray 1 will not tilt even if the bucket is turned upside down on the return side of the bucket travel path.

[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 lower part of the tray on which the objects to be sorted are placed, and the upper part of the tray support. If the saucer is rotatably connected by the pin on one side of these two pins, and the pin on the other side is removable and receives the pin on the other side, the crucian saucer can be held horizontally. A pin receiving part is provided to hold 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 movable member is biased in the lateral direction. A biasing means having a biasing force and causing the pin on the other side to be received in the pin receiving portion by the biasing force is provided, so that when the movable member is moved sideways against the force, the receiving tray catches the receiving tray. Since the buckets of a bucket conveyor type sorter are configured to tilt around the pivoted pin on one side, there are no
Due to the biasing force of the biasing means that biases the movable member in the lateral direction, the pin connected to the movable member via the coupling member is drawn into and received by the pin receiver, and the saucer is stably held horizontally. Therefore, the bucket itself can stably hold the tray horizontally, and the stable receiving rail (guide rail) for holding the tray stably horizontally and traveling can be omitted, and this omission prevents the discharge point from being fixed. This has the effect that the tray can be tilted at a desired location and the materials to be sorted can be discharged.

Furthermore, as described above, the bucket of the present invention is a bucket that can stably hold the receiving tray horizontally in the bucket itself, so there is no need for the above-mentioned stable receiving rail (guide rail) on the return side of the bucket travel path. Moreover, it has the effect that the saucer does 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 fit hole so that the bucket can be assembled in a loose fit manner so that the saucer support 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 general weight measurements.
