Description

[Detailed description of the invention] (Industrial field of application) This invention relates to a device for sorting long and slender plants, and belongs to the industrial field of weighing and sorting devices during transportation.

(Prior art) Various devices are known for weighing and sorting eggs, oranges, etc. while they are being transported.In most of these devices, when the object to be sorted moves to a weighing position, its base plate etc. The structure was such that it could be moved and the openings etc. opened.

(Problems to be solved by invention) However, it is difficult to transport plants with long stems such as chrysanthemums, carnations, and roses one by one to the weighing position, and even if they are transported, it is difficult to transport them one by one to the weighing position. There are no specific proposals regarding the means of weighing. Therefore, the inventor of this application transported the plants horizontally one by one, and rotated the support at the weighing position so that the plants could be dropped and accumulated according to weight. Since the above-mentioned horizontal placement of plants is carried out on the outbound side of the conveyance device, whether automatically or manually, weighing must be done on the return side.
Therefore, when changing direction, the plant must be lowered while being stably supported.

That is, according to the above structure, plants are sorted by weight on the sorting line, but since the plants are long and slender, it is preferable to rotate the support and drop the plants while they are placed horizontally. There was an easy problem to solve.

(Means for Solving the Problems) However, in this invention, the plant support is made rotatable, and whether or not it can be rotated is determined by the support or non-support of the support piece of the support. Therefore, the above-mentioned problem was solved by supporting the support pieces so that they could descend in parallel when changing the direction of the conveying device.

That is, this invention is a device in which an elongated plant is placed horizontally on a support of a transport device, weighed during transport, and sorted by weight, and the support is placed parallel to the direction change position of the transport device. A guide piece for descending was installed in conjunction with the lifting device to constitute a device for sorting long and narrow plants. In the above, the conveying device is constructed by rotatably attaching both ends of supporting tools to two chains laid horizontally at a predetermined interval, and arranging the supporting tools in parallel at a predetermined interval. In addition, the lifting device connects the tip of the tilting rod via a link rod to the lower end of the lifting rod with a guide piece installed at the upper end, and the base end of the tilting rod is rotatably attached to the machine frame.
The side wall of the eccentric cam is in contact with the middle part of the tilting rod. The link rod is extendable and retractable, so that the lifting stroke of the lifting rod can be adjusted. In the above description, the lowering of the lifting rod depends on its own weight, but the lowering of the tilting rod can also be forced by means such as installing a spring between the tilting rod and the machine frame.

(Function of the invention) In other words, this invention has the following effect:
A guide piece for lowering the support in parallel is installed in conjunction with the lifting device, so the support can be lowered in parallel with the plant placed on it, and there is no risk of the support becoming unstable when changing direction, ensuring stable weighing. can be transported to the desired location. Note that the guide piece is adapted to move in synchronization with the movement of the support.

(Example 1) Next, an example of this invention will be described based on the drawings. Rotating shafts 2,

(parallel to the direction) A support 23 is constructed by fixing the base ends of support rods 7, 7 at a predetermined interval. The support rods 7, 7 are bent in an inverted F-shape on the side in order to support the plant 8. A balance weight 22 is attached to each of the horizontal rods 6 in a direction opposite to the protruding direction of the support rods 7, and one end of a support piece 10 made of an elastic material is fixed to one side of the horizontal rod 6 via a bracket 9. ,
The tip of the branch piece 10 protrudes toward the chain 5 side,
It abuts on the fixed guide rail 11. The return path side (lower stage) of the chain 5 is the weighing side, and below there are stacking section frames 12, 12a, 12b, which are divided into several sections in the direction of movement of the chain 5.
12c are arranged in parallel, and each frame is provided with a guide rod 13 on which the branch piece 10 is transferred, and each guide rod 13 can be tilted around a support shaft 15 by an arm 14 (in the direction in which the guide rod 13 side descends). The arm 14 has a fixed weight 16 and a movable weight 16.
a is attached to constitute a weighing device 24, and the weighed weight can be accurately set by moving the movable weight 16a. Further, lifting guide pieces 17 and 18, which raise and lower the support piece 10 in parallel with each other when the chain 5 changes direction, are installed so as to move up and down in synchronization.

On the bottom plates of the frames 12, 12a, 12b, 12c, a predetermined plurality of support rings 19, 19 are rotatably installed at predetermined intervals, and on the support rings 19, 19, pedestals 20 for the plants 8 are respectively mounted. is placed. The pedestal 20 is a planar rectangular plate that fits loosely into the frame 12, and the support ring 19 is provided on the lower surface of the pedestal 20.
Two rails are fixed in parallel at positions corresponding to the chain 5 and can slide at right angles to the direction of the chain 5.

In addition, the branch piece 10 is attached to the bracket 9 by screws 21.
The branch piece 10 is fixed upward, and one end 10a of the branch piece 10 is hooked to the edge of the bracket 9, and the other end of the branch piece 10 extends in the direction of the chain 5, and its angle is adjusted by an adjustment screw 47.

The guide piece 17 is fixed to the upper end of the lifting rod 25, the lower end of the lifting rod 25 is connected to the upper end of the link rod 26, the lower end of the link rod 26 is connected to the tip of the tilting rod 27, and the base end of the tilting rod 27 is connected. is the shaft 28 on the machine frame 1.
It is installed in Further, the cam roller 29 attached to the middle part of the tilting rod 27 is in contact with the side wall of the cam 30 installed on the machine frame 1, and the sprocket 31 fixed to the shaft of the cam 30 and the sprocket 33 fixed to the shaft of the motor 32 A chain 35 is commonly attached to the sprocket 34 and the sprocket 34 fixed to the rotating shaft 2, and power is transmitted synchronously.

The lifting guide piece 18 is fixed to the upper end of the lifting rod 36, the lower end of the lifting rod 36 is connected to the tip of a tilting rod 38 via a link rod 37, and the base end of the tilting rod 38 is attached to the machine frame 1. ing. Said tilting rod 38
The eccentric cam 4 is attached to the cam roller 39 attached to the middle part of the
A chain 43 is installed in common between a sprocket 41 that abuts the side wall of the cam 40 and is fixed to the shaft of the cam 40, and a sprocket 42 that is fixed to the rotating shaft 3 to synchronously transmit the power of the cam.

In the embodiment described above, a plant (for example, a chrysanthemum) is placed on the support rods 7, 7 at part A on one side in FIG.
When the plant 5 is moved in the direction of the arrow 44, the rotation shaft 2 and the output shaft of the motor 32 work together to move the plant 8.
It moves in the same direction while being supported horizontally, then descends and moves in the direction of arrow 45.

In the above, when the support 23 reaches the end of the forward path of the conveyance device, the branch 10 of the support 23 comes off the rail 11 and moves onto the guide piece 17, and as the support 23 moves (descends), the guide piece 17 also descends in synchronization. When the guide piece 17 reaches the lowest position,
The branch 10 transitions to the lower rail. In this way, the support 23 smoothly transitions from the forward path to the return path of the conveying device in the same posture. When the plant 8 reaches the position of the frame 12, the branch 10 is moved onto the guide rod 13. In this case, if the weight of the plant 8 is more than the set weight of the guide rod 13, the guide rod 13 on which the branch 10 is mounted rotates in the direction of arrow 46 (descends as indicated by the chain line 13a in FIG. 4). ), the branch 10 is removed from the guide rod 13, and
Arrow 4 along the slope 11a of the fixed guide rail 11
Since it descends as shown in 9, the horizontal rod 6 is attached to the mounting shaft 5 at both ends.
The plants 8 on the support rods 7, 7 fall in the direction of the arrow 52 and are supported on the pedestal 20. When the weight of the plant 8 is less than the set weight, the guide rod 13 remains horizontal, so the branch 10 passes through as it is and moves on the fixed guide rail 11 as indicated by the arrow 53. As described above, the plants 8 are sorted according to their weights. Once a suitable amount of plants have been accumulated on the pedestal 20, the pedestal 20 is pulled out in the direction of arrow 54 or 55, and the accumulated plants are taken out and packaged.

In the above, once the supporting member 23 has been rotated, since the supporting piece 10 is guided by the groove 56 formed by the lower part of the rail 11 and the guide rod 48, the supporting member 23 moves forward while maintaining its rotated position. Therefore, there is no risk of it becoming unstable while moving or coming into contact with other objects and making noise.
Since the adjustment screw 47 has an elliptical shape (or is eccentric), the angle of the support piece 10 can be finely adjusted by rotating it. Further, the support piece 10 is made of a spring material, and is indicated by an arrow 58 or 5 in FIG.
Since it can move elastically in the direction 9, there is no risk of damage even if some external force is applied while moving.

Note that the support 23 rotates and moves in the direction of the rotating shaft 3 while leaving the plant 8 falling, but since the swash plate 60 is provided below, the lower surface of the support rod 10 touches the swash plate 6.
By moving forward while touching the top surface of 0,
The support 23 sequentially rotates in the direction of the arrow 57 opposite to the above, and returns to the old position (before rotation). Therefore, it enters the frame 18a of the guide piece 18, rises in parallel as the lifting rod rises, and moves to the starting end of the forward path of the support.

(Embodiment 2) FIG. 5 shows another embodiment of the elevating device for the guide piece 17.

That is, the guide piece 17 is fixed to the upper end of the lifting rod 61, and the outer wall of the eccentric cam 63 is in contact with the lower surface of the cam plate 62 at the lower end of the lifting rod 61. It is a spring that comes into contact with the

(Effects of the invention) In this invention, the guide piece of the support is installed at the direction change position of the conveyance device so that it can descend in parallel, so the support can descend in parallel while supporting the plant, moving from the forward transport side to the return side. This has the effect of allowing you to transition in the same posture. Therefore, return route selection can be performed smoothly.
