Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a constant size cutting machine for corolla and flower stalks used in a weight sorter using an electronic measuring instrument for electric shine.

[0002]

2. Description of the Related Art Conventionally, an electronic measuring instrument (load cell) has a high accuracy and therefore has a large measurement unevenness. In addition, it was difficult to cut the length from the corolla of the elephant chrysanthemum to the base end of the stem evenly, only by manually guiding the corolla.

When the stem is gripped and the corolla is fed along the guide plate, the corolla is not always in contact with the guide plate by human power, and even if it is in contact, the corolla is compressed by the contact pressure. This is because the base end of the stem is cut.

[0004]

SUMMARY OF THE INVENTION The present invention is a fixed-sized flower sizing machine that can cut a length from the tip of a corolla to the base end of a stem to a uniform length, even though it is a human-powered guide feeder. Aim to get a cutting machine.

[0005]

In order to achieve the above object, the present invention provides a machine frame with a plurality of parallel conveyors, and a plurality of pushing rods are installed upright at equal intervals at corresponding positions of the conveyors. A corolla guide plate is provided at the front end, a corolla guide plate is erected on one side of the guide plate in the direction of the conveyor, and a corolla constant-size push-out plate is provided so as to be able to move in and out from the rear end of the corolla guide plate with a space therebetween. , Providing a corolla detector between the center line of the extruded plate and the corolla guide plate,
A flower selection in which a solenoid is operated by a delay control device of a signal from the detector to move the push-out plate in and out to push a corolla to the conveyor side, and a base end cutter of the pushed flower stem is provided in a machine frame. Sizing cutter A flower stalk drop guide guide is provided at the end of each of the parallel conveyors, and a rear end upwardly bent flower stalk receiver is arranged below the guide.
The flower stalk receiver is constituted by the sizing flower cutting machine described in the above invention, which is supported by an electronic scale.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, the corolla 11 is brought into contact with, pressed against or slightly separated from the inner surface of the corolla guide plate 5 so that the corolla 12 is placed horizontally on the corolla guide plate 4 at right angles to the respective conveyors 2. Pushing rods 3, 3, 3 provided upright on the conveyors 2, 2, 2 transfer the corolla 11 and the flower stem 12 to the rear ends of the respective conveyors 2, 2, 2.

At the stage of the above-mentioned transfer, the corolla 11 is detected by the detector 7, and the solenoid 10 is excited by the detection signal 8 to extrude the corolla constant-size extruding plate 6 by a constant width t. The control device 9 delays this signal 8 by a slight time from the time when the corolla 11 is detected until the corolla 11 reaches the center line c of the pushing plate 6.
As a delay signal, the solenoid 10 is excited immediately before the apex corolla 11 coincides with the center line c of the extruding plate 6, and the extruding plate 6 is resisted against the ridge by a constant width t (fixed size) from the solid line position in FIG. The push-out plate 6 is pushed out to the imaginary line position, the corolla 11 and the flower stem 12 are slid to a fixed position, then the signal 8 is opened and the solenoid 10 is demagnetized, and then the pushing plate 6 is returned to the original position by the force of the spring.

At the above-mentioned fixed positions of the corolla 11 and the stem 12, the proximal end 12 'of the corolla is cut by the cutter 13 so that the length from the corolla 11 to one end of the corolla 12 is evenly cut.

After that, the corolla 11 and the flower stem 12 are moved by the conveyor rods 2, 3, 2 by the push rods 3, 3, 3.
2 and 2 are guided by the drop guide guide 14 to fall, are supported on the rear end upward bending flower stem receiver 15, the weight is momentarily measured by the electronic scale 16, and a measurement signal is transmitted to measure the measured value. It can be sent to the flower selector 17 via a record or a computer.
