Description

  The present invention relates to an onion root cutting machine. In addition, the onions which are the target of root cutting in the present invention include raccoon, garlic, lily root, bulb and the like in addition to the onion itself.

  The harvested onion must be dried for a predetermined period and then roots must be excised at the time of shipment. Conventionally, the onion root excision work is generally performed manually with scissors.

  By the way, at the time of onion shipment, it is necessary to perform a large amount of onion root cutting work in a short period of time, and the roots extend in an irregular direction. In the work, the work efficiency is very bad, and continuing the root cutting work for a long time is a very tired work.

  Therefore, the present applicant has already proposed an onion root cutting machine disclosed in Utility Model Registration No. 2568657 (Patent Document 1).

  This known onion root cutting machine has a pair of left and right brush rolls (the upper surface sides rotate inward from each other) arranged close to each other, and a root cutting device (a pair of disk blades) at the end of the brush roll. Is provided.

  And in this known onion root cutting machine, hold the onion in your hand and lightly press it against the upper side valley between the brush rolls with the root facing downward, so that the onion roots are removed with the brush rolls on both sides. By hanging downward and moving the onion laterally to the root cutting device side in the hanging state, the root portion of the root can be cut by the root cutting device (two disc blades).

Utility Model Registration No. 2568657

  However, in the onion root cutting machine of the above known example (Patent Document 1), after turning the onion root downward and pressing between both brush rolls, the onion root cutting machine can be cut horizontally by moving laterally to the root cutting device side. Therefore, although it can be done relatively lightly, it is necessary to manually operate the onions one by one, so there are many points to be improved in terms of efficiency and workability.

  Accordingly, the present invention aims to provide an onion root cutting machine that can automatically remove the onion roots by simply dropping the onions to be rooted from the input section and then automatically cutting off the onion roots. It is said.

  The present invention has the following configuration as means for solving the above problems. The present invention is intended for an onion root cutting machine. In the present invention, the onion to be rooted is not limited to the onion itself, but raccoon, garlic, lily root, bulb, etc. Is included. In the following description, the onion itself will be described as an onion to be rooted.

[Invention of Claim 1 of the Present Application]
The onion root cutting machine of the invention of claim 1 of the present application is
A pair of rolls arranged in a horizontal position close to the left or right or in contact with each other between a charging part and a discharging part in a main body case provided with an onion charging part on the front side and an onion discharging part on the rear side, and between the two rolls Set up a transfer roll body that can be put onion on the top surface of the
Each roll is configured by spirally arranging a spiral portion having a function of causing the rotating shaft to feed the onion backward and a belt-like brush material having a function of hanging the root of the onion downward,
Each roll of the transfer roll body is configured so that the upper surface side of each roll is rotated toward the inside by the power unit,
By putting onions on the upper surface between both rolls in the driving state of the transfer roll body, it is configured so that it can be fed back by the left and right coil materials of each roll while hanging the onion root by the left and right brush materials of each roll. And
In the vicinity of the end portion of the transfer roll body, a root cutting device for cutting the onion root discharged from the transfer roll body is installed.
It is characterized by this.

  For example, a coil material can be used for the spiral portion provided in each roll. Further, the spiral portion may be a single one, or two ones may be installed with an interval in the roll length direction. The brush material is a belt-like material arranged in a spiral shape within the interval between the spiral portions.

  The spiral portion of each roll and the brush material are set so that their outer peripheral surfaces are substantially the same (the diameter of the coil material portion may be slightly smaller than the diameter of the brush material portion). And in the state which these both rolls adjoined (or contacted), while the spiral part outer ends of each side are in contact (or almost in contact or proximity) on the facing part, the brush material outer ends of each side Are in contact with each other. The outer ends of the brush materials on each side may be polymerized by a predetermined small length (for example, 1 to 2 mm).

  As for the diameter of each roll, one having an appropriate thickness can be employed depending on the type (size) of onions to be rooted. For example, for onions, a roll having a diameter of about 10 cm to 12 cm is suitable. For example, a small roll such as a rakkyo is suitable for a roll having a diameter of about 3 cm to 4 cm. Regardless of the size of the roll diameter, it is the same that the spiral portion and the brush material are arranged spirally on the outer periphery of the roll.

  In the onion root cutting machine according to claim 1, the onions in the state where the roots are cut are automatically discharged from the discharge section as follows by simply dropping the onions sequentially from the input part of the main body case. It has become.

  That is, when the onion is dropped from the input part of the main body case while the transfer roll body is driven by the power unit, the onion rolls in a state where it is placed between both rolls of the transfer roll body. Part of the onion root is drawn into the contact area between each brush material. As a result, the entire root of the onion is sequentially drawn between the brush materials, so that the onion is changed to a posture in which the root is directed downward (upright posture). In addition, although the root of an onion is comparatively thin, when each brush material outer end of both rolls is contacting (or superposing | polymerizing only small length), even if a root is thin, it can draw in reliably. In the state where the onion is in the upright posture, the entire root is swung downward with the left and right brush materials, so that each root is extended to a state close to a straight line.

  On the other hand, the onions in the upper side valley between the two rolls are suspended downward as described above, and at the same time the left and right spirals remain in an upright position on the transfer roll body from the discharge part side to the discharge part. Sent back to the side. Then, the onion is discharged from the end portion of the transfer roll body in an upright position, and then the root of the onion is cut by a root cutting device, and the onion that has been excised is discharged from the discharge portion. .

  As described above, the onion root cutting machine of the present application can automatically perform the onion root cutting operation by simply dropping the onion from the input portion of the main body case.

[Invention of claim 2 of the present application]
The invention of claim 2 of the present application is the onion root cutting machine according to claim 1, wherein the root cutting device uses a pair of left and right disk cutters installed in a horizontal posture, and the upper surface of each disk cutter. The pair is provided with a pair of left and right elastic rolls for elastically holding the onion discharged from the end portion of the transfer roll body from the left and right sides and allowing the onions to pass over the cutting portions of the disk blades.

  By the way, it is desirable to maintain the onion discharged from the terminal end of the transfer roll body in an upright posture (root is downward) until the root cutting operation is completed by the root cutting device. In the onion root cutting machine, the onion discharged from the end portion of the transfer roll body can be passed over the cutting portions of both disc cutters while elastically sandwiching between the left and right elastic rolls in an upright position. . Therefore, the onion root can be cut accurately and cleanly at the root portion.

[Effect of the invention of claim 1 of the present application]
The onion root cutting machine according to claim 1 of the present application is, as described in claim 1, a brush material having a spiral part and a pendulum function on the outer periphery as the roll of the transfer roll body. Each one is arranged in a spiral shape, and by simply dropping the onion from the input section, the root cutting operation can be completed automatically thereafter.

  Therefore, the onion root cutting machine according to the first aspect of the present invention has an effect that the onion root cutting operation can be efficiently processed (a large amount can be processed in a short time) and only light operations can be performed.

[Effect of the invention of claim 2 of the present application]
The root cutting machine for onions according to claim 2 of the present application, as described in claim 2 above, elastically holds the onions discharged from the end of the transfer roll body between the left and right elastic rolls in an upright position. However, since the onions can be passed over the cutting portions of both the disk cutters, the root cutting work with the disk cutters can be performed while maintaining the onions in an upright posture.

  Therefore, in the onion root cutting machine according to the second aspect, in addition to the effect of the first aspect, the onion root cutting by the root cutting device (disk cutter) is accurately (at the root) and reliably (no failure). To the effect).

[Example]
Hereinafter, the onion root cutting machine according to the present embodiment will be described with reference to FIGS. In the following description, in the plan view of FIG. 1, the left side is the “front” side that is the onion input side, the right side is the “rear” side that is the onion discharge side, and the upper side is “left” as viewed from “front”. The lower side is the “right” side as viewed from the “front”. In each figure, onions are marked with T1 to T4, and onion roots are marked with N, and T1 to T4 indicate the onions at their respective positions.

  As shown in FIG. 1, the onion root cutting machine of this embodiment has one onion transfer device 2 and one root cutting device at two left and right locations in the main body case 1 (up and down two locations in the state of FIG. 1). One set of root processing devices composed of 4 is arranged (two sets in total). The two sets of root treatment devices (each composed of an onion transfer device 2 and a root cutting device 4) are the same as each other. In the following description, the “right” side (in FIG. Side) will be described.

  The main body case 1 is enclosed by a two-dot chain line in FIG. The front portion of the main body case 1 is provided with two input portions 11 and 11 that are spaced apart from each other (up and down in FIG. 1), while the rear portion of the main body case 1 corresponds to the input portions 11 and 11. Two discharge portions 12, 12 are provided at the positions. Note that the charging unit 11 may be referred to as a charging chute, and the discharging unit 12 may be referred to as a discharging chute.

  Between the input unit 11 and the discharge unit 12 in the main body case 1, a transfer roll body 20 including two rolls 21 and 22 as a set, and a root N of the onion T that is fed later by the transfer roll body 20. A root cutting device 4 is installed. In addition, two sets of root processing apparatuses which use this transfer roll body 20 and the root cutting device 4 as one set are used on the left and right sides (up and down in FIG. 1).

  Also, the rolls 21 and 22 (four in total) of the left and right transfer roll bodies 20 and 20 are a common power unit 3 as shown in FIG. It can be rotated. In other words, the pair of rolls 21 and 22 are rotated by the power unit 3 so that the upper surfaces of the rolls face each other. And, the transfer roll body 20 composed of a pair of rolls 21 and 22 and the power unit 3 constitute an onion transfer apparatus 2 for feeding onions as described later. In this embodiment, There are two onion transfer devices 2 on the left and right (see FIG. 1). The power unit 3 for the transfer roll bodies 20 and 20 includes a single motor 31 and a power transmission member 32 composed of a sprocket and a chain.

  In this embodiment, each of the left and right rolls 21 and 22 constituting the transfer roll body 20 has a coil-like spiral portion 24 having an onion feed function on one rotating shaft 23 and a strip-like shape having an onion hanging function. Each of the brush members 25 is spirally wound. That is, in each roll 21, 22, the spiral portion 24 and the brush material 25 appear alternately in the roll length direction in a plan view (FIG. 1) and a side view (FIG. 2). In this embodiment, the spiral portion 24 provided on each of the rolls 21 and 22 is configured by winding a coil material. Therefore, in the following description, the spiral portion 24 may be referred to as a coil material.

  As shown in FIG. 1, the pair of rolls 21 and 22 is reverse to the one in which the coil material (spiral portion) 24 and the brush material 25 are spirally wound so as to advance in the clockwise direction (the roll denoted by reference numeral 21). The coil member 24 and the brush member 25 are spirally wound so as to advance in the counterclockwise direction (roll of reference numeral 22). In this embodiment, only one coil member 24 is wound around one rotating shaft 23. However, in another embodiment, two coil members 24 are wound around one rotating shaft 23. It can be attached.

  The coil material 24 and the brush material 25 in each of the rolls 21 and 22 are set so that their outer peripheral surfaces are substantially the same. In another embodiment, the diameter of the coil material 24 portion may be slightly smaller than the diameter of the brush material 25 portion.

  The thickness of each of the rolls 21 and 22 (each diameter of the coil material 24 and the brush material 25) is preferably about 10 cm to 12 cm (not particularly limited) for onions. For example, in the case of a small object such as a lacquer, the rolls 21 and 22 preferably have a diameter of about 3 cm to 4 cm. Regardless of the roll diameter, it is the same that the coil material (spiral part) 24 and the brush material 25 are spirally arranged on the outer periphery of the roll.

  As shown in FIG. 1, both the rolls 21 and 22 are arranged close to each other (or in contact) between the input portion 11 and the discharge portion 12 in the main body case 1. That is, in the arrangement shown in FIG. 1, the outer ends of the coil members 24, 24 on each side are in contact with each other at the facing portion (may be in a slightly spaced proximity state), while the brush members 25 on each side, The outer ends of 25 are in contact at the facing portion. The outer ends of the brush members 25 on each side may be polymerized by a predetermined small length (for example, 1 to 2 mm).

  Left and right guide plates 13 and 13 that are inclined downward toward the upper surface near the outer periphery of each of the rolls 21 and 22 are provided on the left and right positions on the upper side of the transfer roll body 20 including both rolls 21 and 22. Each of the guide plates 13 and 13 prevents the onion from falling off left and right.

  In the transfer roll body 20, the rolls 21 and 22 are rotated by the power unit 3 in the directions indicated by the arrows in FIGS. 1 to 4 (inward directions relative to each other). It acts as follows on the onions on the part.

  That is, when the onion is dropped from the charging unit 11 onto the transfer roll body 20 in the operation state (position T1), the onion rolls in the upper side valley between the rolls 21 and 22, and the onion at this time The posture is unspecified. When the onion rolls, first, a part of the root N of the onion T1 is drawn downward by the left and right brush members 25, 25, and then the entire root N of the onion T1 is drawn by the two brush members 25, 25. Drooped in between. At this time, the onion is maintained in the upright posture state as indicated by reference numeral T1 in FIG. Although the onion root N is relatively thin, if the outer ends of the brush members 25, 25 of both rolls 21, 22 are in contact with each other (or a small length is polymerized), the root is thin. Can be reliably pulled in.

  On the other hand, the onions placed on the upper surface side troughs between the two rolls 21 and 22 are sequentially fed in an upright posture by the coil members 24 and 24 of the both rolls 21 and 22. In other words, the onion is sent back from the position of the symbol T1 in FIG. 1 and FIG. 2 to the position of the symbol T2 in an upright posture (or while facing the upright posture). The onion back-feeding function also works with the brush members 25 and 25 together with the coil members 24 and 24.

  A root cutting device 4 having a pair of left and right disk blades 41, 41 is provided in the vicinity of the terminal end of the transfer roll body 20. The root cutting device 4 has disk cutters 41, 41 attached to two longitudinal shafts 40, 40, respectively, and the disk cutters 41, 41 are connected to the roots of the onion root N at positions near the terminal end of the transfer roll body 20. The height is set so that the part can be cut (see FIG. 5). Further, the vertical shafts 40, 40 are moved by the power unit 5 in the direction of the arrow shown in FIG. 1 (the direction in which the overlapping portions of the disk blades 41, 41 rotate from the “front” side toward the “rear” side). It can be rotated. In addition, each set of the disk blades 41 and 41 of the root cutting device 4 is installed in the vicinity of the end portions of the two sets of transfer roll bodies 20 and 20, respectively. As the power unit 5, a single motor 51 and a power transmission member (sprocket and chain) 52 hung around each of the longitudinal shafts 40 (four in total) on both sides are used.

  In this embodiment, elastic rolls 42 and 42 are respectively attached to the upper surface portions of the disk blades 41 and 41. Each of the elastic rolls 42, 42 can be made of a soft sponge that compresses and recovers in the radial direction, but a brush roll can also be used. The diameters of both elastic rolls 42 and 42 are set so that the distance between the opposing portions of both elastic rolls 42 and 42 is considerably smaller than the diameter of the onion (for example, set to an interval of about 2 to 3 cm). The function of the elastic rolls 42 will be described later.

  Below both the disk cutters 41, 41, a root receiving chute 14 for guiding the roots of the onion cut by the disk cutter as described later is provided. Further, below this root receiving chute 14 is installed a root receiver X that accommodates the cut onion.

  A discharge chute 12 serving as a discharge portion is attached to the “rear” side of both the disk cutters 41, 41 (there are two places on the left and right). In addition, an onion receiver Y is installed below the discharge chute 12 to accommodate the onion T4 having undergone root cutting.

  In the onion root cutting machine of this embodiment, the onion T4 in a state in which the roots are cut as follows is automatically obtained by simply dropping the onion with the roots sequentially from the input part (input chute) 11 of the main body case 1. It is discharged from a discharge part (discharge chute) 12.

  That is, when the power device 3 on the onion transfer device 2 side and the power device 5 on the root cutting device 4 side are operated, the rolls 21 and 22 of the transfer roll body 20 (two sets) rotate inward with respect to each other. On the other hand, the pair of disc blades 41, 41 (and the elastic rolls 42, 42 thereon) rotate. Then, when the rooted onion is dropped from the charging chute 11 (two places) of the main body case 1 in this operating state, the onion is placed on the upper surface side trough between the rolls 21 and 22 at a position near the starting end of the transfer roll body 20. Mounted (position of reference T1). Then, when both rolls 21 and 22 rotate, the onion rolls. At this time, a part of the root N of the onion is at the contact portion between the brush materials 25 and 25 of both rolls 21 and 22. The whole onion root is drawn in between the brush members 25 and 25 in accordance with this, and the onion is changed to an upright posture (the posture indicated by reference numeral T1 in FIG. 2) with the root facing downward. At this time, in the upright posture of the onion T1, the entire root N is scraped downward by the left and right brush members 25, 25, so that each root N is extended to a state close to a straight line.

  On the other hand, the onion T1 in the upper surface side trough between both rolls 21 and 22 has the root N hanging downward as described above, and at the same time the left and right coil members 24 and 24 remain in an upright posture. 2 is sent back from the input unit 11 side to the discharge unit 12 side. At this time, since the root N of the onion is drawn downward by the both brush members 25, 25, the lower surface of the onion reliably comes into contact with the coil members 24, 24, thereby ensuring the onion feed function. .

  Thus, each roll 21, 22 of the transfer roll body 20 has both the onion hanging function by the brush material 25 and the onion post-feed function by the coil material 24, so the onion on the transfer roll body 20. The onions can be sequentially postponed in an appropriate posture (upright posture) simply by dropping the.

  Then, the onion is transferred to the end portion of the transfer roll body 2 in an upright position (position T2), and then is discharged to the disk cutter 41, 41 side. , 41 is passed over the cutting part (blade edge overlapping part) (reference numeral T3), the root portion of the root N of the onion T3 is cut by the two disc blades 41, 41.

  By the way, when cutting the onion root with the disc blades 41, 41, it is desirable to keep the onion in an upright position as much as possible in order to cut the root N cleanly. Therefore, in this embodiment, when the onion is discharged from the end portion of the transfer roll body 20, the onion is directly held between the elastic rolls 42 and 42 on the disk blades 41 and 41, respectively. . In the state where the onion T3 is sandwiched between the two elastic rolls 42, 42, the sandwiched portions of the two elastic rolls 42, 42 are recessed along the outer shape of the onion as indicated by reference numerals 42a, 42a in FIG. (This dent 42a returns to its original state when the onion passes).

  When the onion is sandwiched between the elastic rolls 42 and 42 in this way (reference numeral T3 in FIGS. 1 and 5), the onion T3 can be maintained in an upright posture, and the root N is surely suspended downward. And when this onion T3 is passed over the cutting part (blade edge superposition | polymerization part) of the disk blades 41 and 41, with both elastic rolls 42 and 42 clamped, the root N of this onion T3 can be correctly cut | disconnected by a root part.

  The root N cut by the disk blades 41 and 41 passes through the root receiving chute 14 and is accommodated in the root receiver X, while the onion T4 having undergone the root cutting that has passed through the disk blade cuts the discharge chute 12. And is accommodated in the onion receiver Y.

  As described above, the onion root cutting machine of this embodiment simply drops the onion onto the transfer roll body 20 from the charging chute 11, and the onion root hanging operation and the onion post-feeding operation are automatically performed. Further, after the root cutting operation by the root cutting device 4, the rooted onion can be automatically recovered. Accordingly, there is an advantage that the onion root cutting work can be efficiently performed and the root cutting work is light.

  1 is a main body case, 2 is an onion transfer device, 3 is a power device, 4 is a root cutting device, 5 is a power device, 11 is an input portion (input chute), 12 is a discharge portion (discharge chute), and 20 is a transfer roll body 21 and 22 are rolls, 23 is a rotating shaft, 24 is a coil material, 25 is a brush material, 41 is a disk cutter, 42 is an elastic roll, T1 to T4 are onions, and N is a root.
