Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for adjusting the objects to be sorted such as ginseng and automatically supplying the sorted objects one by one to a weight sorter.

[0002]

[Prior art]

 An example of a conventional weight sorter is shown in Japanese Utility Model Laid-Open No. 1-69090. The sorting machine is provided with a pair of parallel endless chains on the machine frame, connecting rods for connecting the chains are provided at equal intervals, and the front end portion of the weighing tray is rotatably supported on the connecting rod, and the rear end portion thereof is supported. The horizontal projection on the upper side of the chain is slidably supported on a horizontally fixed guide guide that is horizontally supported to support the pan horizontally, and the guide allows the weight of the weighing machine to be raised and lowered. It is described that a known roller conveyor is used as a means for supplying the objects to be weighed to the receiving tray.

[0003]

[Problems to be solved by the device]

 However, in this roller conveyor, long objects such as ginseng may be sent out in the vertical direction, or multiple pieces may be simultaneously supplied to one saucer, which hinders the smooth and accurate sorting work of the weight sorter. There is a problem.

[0004]

[Means for Solving the Problems]

 The present invention is provided with a large number of cups for individually receiving the objects to be sorted such as ginseng and one or more measuring and rotating means in the course of the movement of the cups so that the objects to be sorted are weighed by the rotation of the cups. This is a device that supplies the objects to be sorted to a weight sorter of the type that drops and sorts separately, and is synchronized with the movement of the cup by tilting the top of the cup at the base end position of the move of the weight sorter. A rotating endless conveyor and a large number of lifting pieces that are compact enough to allow the center of gravity of the objects to be sorted to be placed at a fixed interval on the conveyor, and the conveyor side should be placed outside the middle of the conveyor. An inclined supply table for the objects to be sorted is provided, and alternate swinging toward the side of the lifting piece is repeated on both insides of the inclined supply table to prevent the objects to be sorted from accumulating and to carry an extra load. Barber slide that pushes down the objects to be sorted from the upper piece Provides automatic feeder providing a plate, it is intended to solve such problems.

[0005]

[Action]

 According to the present invention, when an object to be sorted such as a ginseng is stored on an inclined feeding table and the apparatus is started together with a weight sorter, the lifting piece on the feeding table side is moved up by the rotation of the conveyor and the dressing sliding plates on both sides are moved. Repeats alternating swing toward the central lifting piece. The group of objects to be selected on the inclined feeding table is adjusted while being shaken by the upward movement of the lifting piece and the swing of the adjusting slide plate, and is transferred one by one onto the lifting piece due to the inclined gravity of the feeding table, The objects to be sorted from the upper end to the back surface are dropped and supplied one by one to each cup that moves synchronously. When two or more objects to be sorted are placed side by side on the lifting piece, the excessive objects to be sorted will be pushed down on the way by the swing of the dressing sliding plate.

【Example】

 Embodiments will be described below with reference to the drawings.

A large number of cups 2 are attached between a pair of parallel endless chains 1 and 1, one side of which is pivotally attached and the other side is rotatably provided, and a constant weight is set at several points during movement of the cups 2. By the above load operation, the cup 2 is pivoted downward to drop the object A to be sorted. And the endless conveyor 5 is mounted so as to be inclined. 6 is a machine frame of the conveyor 5.

On the outer circumference of the endless conveyor 5, a large number of lifting pieces 7 projecting radially at regular intervals are provided horizontally, and the conveyor 5 side is placed on the outside of the middle of the endless conveyor 5 below the linear moving part. An inclined supply table 8 for the objects A to be sorted is provided. The lifting piece 7 has a width and depth that are as compact as possible in such a size that the center of gravity of the object A to be sorted, which is the largest in length and thickness, can be stably accommodated, and the distance between the lifting pieces 7 is 2 The size is set so that more than one object A to be sorted will not be stacked. It should be noted that it is desirable that the essential parts of the lifting piece 7 and the inclined supply table 8 are made of rubber or an elastic body 9 is attached so as not to damage the object A to be sorted.

On the inner sides of both sides of the inclined supply table 8, there are provided cuboidal shape-regulating sliding plates 10 and 10 which swing horizontally along the machine frame 6. The dressing sliding plates 10 and 10 are integrally supported by a support frame 11 with an interval enough to accommodate the object A having the maximum length. The support frame 11 is attached to a group of guide rollers 12 mounted on the machine frame 6. When fitted together, it can move laterally, and the lateral movement of the power-equipped crank mechanism 13 attached to the bottom of the support frame 11 causes the dressing sliding plates 10 and 10 to face the side of the lifting piece 7. It is designed to continuously repeat alternating swings. Reference numeral 14 is a rubber guide plate provided from the upright pieces 8a, 8a on both sides of the inclined supply table 8 toward the dressing sliding plates 10, 10.

In the embodiment, the power of the endless conveyor 5 is obtained from the power gear shaft 1a of the endless chain 1 of the weight sorter 4 via the transmission chain 15, but it is independent and can be synchronized with the moving speed of the cup 2. A power source can also be used.

The apparatus of the present invention having the above-described configuration is started together with the weight sorter 4, and the group A of objects to be sorted such as a humane is placed on the inclined feeding table 8 manually or by a known conveying means. Then, the group A of objects to be sorted is adjusted by the upward movement of the lifting piece 7 and the swinging of the dressing sliding plates 10 and 10, and between the lifting pieces 7 which move up one by one by the inclination of the inclined supply table 8. It rolls into the gap, is conveyed, and when it reaches the back side from the upper end of the endless conveyor 5, it is naturally dropped and placed in the cup 2 at the base end of the weight sorter 4.

As shown in FIG. 3 (a), when two objects A to be sorted are placed side by side on one lifting piece 7, due to the action of the dressing sliding plates 10 and 10 which alternately swing. As shown in Fig. 3 (b), one of the dressing sliding plates 10 that hits the other side is pushed out, the center of gravity is destroyed, and it falls from the lifting piece 7, so one lifting piece Only one item A to be sorted can be placed on item 7. Further, the objects to be sorted A, which are deflected to the side of the lifting piece 7, are repelled by the swinging dressing slide plates 10, 10 and return to the inclined feed table 8 again to be sequentially transferred onto the lifting piece 7. It will be. The group A of objects to be sorted is constantly rocked by the rocking of the dressing sliding plates 10 and 10, so that there is no accumulation such that the transfer to the lifting piece 7 is stopped.

[0013]

[Effect of device]

 As described above, according to the present invention, a large number of compact lifting pieces are horizontally provided around an endless conveyor at regular intervals, and an inclined feeding table having a low conveyor side is provided outside the middle of the conveyor. Since the adjusting sliding plates that repeat alternating swinging toward the side of the lifting piece are provided on both insides of the inclined supply table, the objects to be sorted, which are randomly input, are adjusted without fail, and the 1 is ensured. One by one can be automatically supplied to the cup of the weight sorter, the weight sorter can be operated smoothly, and it is possible to prevent mistakes in sorting when supplying two or more objects to be selected at the same time. This brings about the effect that it is possible to perform proper selection.
