Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a device for cutting the roots and leaves of root vegetables such as carrots.

[0002]

[Prior Art]

 A device for cutting the foliage of ginseng after harvesting with a rotary blade is known from Japanese Utility Model Publication No. 62-130493. The known device is a conveyor provided with a partition member for separating carrots one by one, a cushion receiving portion provided between the partition members, and a cushion roll for pressing the carrot placed on each cushion receiving portion from above. Then, while holding the carrot with the cushion roll and cushion holder, cut the foliage with a rotary blade. However, it is difficult for this device to reliably hold and cut carrots that are larger than the inner width of the cushion receiver and to cut them, and the carrots move during cutting, resulting in poor cutting accuracy. It was being done.

The device proposed by Japanese Utility Model Laid-Open No. 62-57698 grips carrots between the protrusions of the upper and lower conveyors in which triangular protrusions facing each other are arranged side by side, and pushes the upper conveyor downward by the intermediate pulley. Therefore, it is possible to hold the carrots reliably during cutting even if the root diameters of the carrots vary. However, this device has a problem that the device is complicated and the cost is high because the conveyor is vertically installed.

[0004]

[Problems to be solved by the device]

 The present invention has been made to solve the above-mentioned problems, and its purpose is to maintain the root vegetables during cutting of the rotary blade even if the root diameter and root length of the harvested root vegetables are relatively large. An object of the present invention is to provide a device capable of reliably grasping a variety of vegetables and cutting the foliage of root vegetables with high cutting accuracy.

[0005]

[Means for Solving the Problems]

 To achieve the above object, the means adopted by the present invention is a pneumatic tube for arranging trays having a V-shaped cross section on a conveyor side by side and pressing the root neck of root vegetables on the tray immediately before the rotary blade. That is, the rolls were arranged and the pneumatic tube roll was rotationally driven at a speed according to the conveyor speed.

[0006]

[Action]

 Since the dish that receives root vegetables has a V-shaped cross-section, the root neck always contacts the dish surface at two points, regardless of the size of the root diameter and root length. Press the root and neck with a pneumatic tube roll. At this time, the pneumatic tube roll is dented according to the size of the root neck, and the larger the rhizome presses against the dish with stronger force and grips it, so even large root vegetables with large cutting resistance move during cutting. Is cut with high accuracy.

【Example】

 A device of the present invention will be described based on an embodiment shown in the drawings. As shown in FIG. 1, driven pulleys 10 and 11 are axially supported on a machine frame 12, and a conveyor belt 3 is driven and driven around the conveyor belt 3. A receiver 5 for supporting the conveyor belt 3 from below is attached to the machine frame 12. A large number of trays 4 having a V-shaped cross section are arranged on the conveyor belt 3 at equal intervals. The motor 2 is attached to the machine frame 12, and the transmission 1 is directly connected to the output shaft of the motor. The rotation of the transmission output shaft is directly transmitted to the drive pulley 10 and the rotary blade 9 via the chain or belt 6. The rotation of the drive pulley 11 is transmitted to the pneumatic tube roller 8 via the chain or belt 7. The pneumatic tube roller 8 is located slightly upstream of the rotary blade 9 in the traveling direction of the conveyor belt, and its lower surface is at a height where it contacts the upper edge of the dish 4 on the conveyor belt. The rotary blade 9 is located lower than the pneumatic tube roller 8 and its lower surface is below the bottom of the dish 4.

As shown in FIG. 2, the rotary blade 9 has its axis perpendicular to the traveling direction of the conveyor belt, and its cut surface is parallel to the traveling direction of the conveyor belt 3 and is on a vertical surface close to the outer end of the tray 4. is there. The axis of the pneumatic tube roller 8 is orthogonal to the traveling direction of the conveyor belt, and its peripheral surface is on the parallel surface of the dish 4 when viewed from above, but approaches the end surface of the rotary blade 8. As shown in the figure, one root vegetable such as carrot is placed on each plate 4 on the conveyor belt 3 and sent to the rotary blade 9. Since the dish 4 has a V-shaped cross section, regardless of the root diameter and the root length of the root vegetable, at least the root diameter portion contacts the dish 4 at two points. The root vegetables are pressed from above by the pneumatic tube roller 8 before the rotary blade 9. At this time, the pneumatic tube roller 8 is dented by the root vegetables, and the dent is larger as the root diameter is larger. The larger the dent, the larger the root vegetable gripping area of the pneumatic tube roller 8, so the larger the rhizome, the stronger the grip. Since the pneumatic tube roller 8 is rotationally driven at a peripheral speed substantially equal to the traveling speed of the conveyor belt 3, the rhizome is cut by the rotary blade 9 while being pressed and grasped by the pneumatic tube roller 8 on the dish 4. .. At this time, the larger the root diameter, the stronger the grip, so it cannot escape and is reliably cut. Therefore, the cutting accuracy is improved.

[0009]

[Effect of the device]

 As described above, according to the present invention, since the root vegetables placed on the dish having a V-shaped cross section on the conveyor belt are pressed and held by the pneumatic tube roller, the cushion rolls are used to hold the root vegetables placed on the conventional cushion receiver. Unlike those that can reliably cut only root vegetables with root diameters and root lengths that match the receiving inner width, it is possible to perform high-precision cutting regardless of the difference in root diameter and root length of root vegetables. Compared to the conventional one, in which the root vegetables are gripped by the upper and lower conveyor belts regardless of the size of the root diameter and the root length, the upper conveyor belt is not required, so the structure is simple and the operation is easy. ..
