It is cut into a predetermined size and used according to the cooking method. Above all, radish for oden sold at convenience stores and the like is required to process a large amount of radish into a certain standard size. Generally, this kind of radish is cut into slices, and the outer skin portion is cut out by hand using a cutting tool, thereby obtaining a radish having a predetermined shape (that is, a uniform cylindrical shape).

[0003]

However, in the work of cutting the outer skin of the radish by hand, the outer periphery must be cut and removed while holding the thick radish with one hand, so that the efficiency of the cutting work is low and the removal is also difficult. There is a problem that the number of parts to be formed increases and the product yield decreases. In addition, from the viewpoint of maintaining the quality of radish, it is difficult to uniformly cut to the required shape and dimensions. In other words, there is a problem that the shape and dimensions of the radish, which is a processed product, are likely to vary, and a long working time and experience are required of the operator in order to ensure high processing quality of the same standard. The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a radish punching apparatus capable of mechanizing a cutting operation of a radish outer peripheral portion, improving yield and securing high processing quality. is there.

[0005] A chute is provided between the conveying means and the holding means for sequentially transferring the radish one by one downwardly, and the lower end of the chute adjusts the timing of transferring the radish to the holding means. For this purpose, a transfer adjusting member is provided. The movement of the radish sliding on the chute is temporarily reduced or stopped by the transfer adjusting member, and thereafter, the radish is intermittently transferred in synchronization with the rotation speed of the holding means.

The transfer means has a rotating belt which rotates around a horizontal axis, and a plurality of mounting plates are erected on the rotating belt at regular intervals. A configuration is adopted in which only one radish can be accommodated between a plurality of mounting plates, and two or more radishes are not accommodated. For example, by setting the distance between the mounting plates and the mounting angle, or the size and shape of the mounting plate according to the diameter range of the target radish, only one radish is placed on the mounting plate. It can be inserted and placed. In addition, a contact removing member for contacting and removing the second radish is provided at an appropriate position in the transporting section, so that a plurality of radishes can be prevented from being mounted on one mounting plate. Is also good.

The holding means rotates continuously at a constant speed about the horizontal axis. The holding unit is driven by a rotary drive source, and a timing belt or a drive transmission chain is stretched between the rotary drive source and components such as a transport unit, a transfer adjustment member, and a product take-out unit described below. And holding means can be operated synchronously. Outside the horizontal axis in the radial direction,
A plurality of sets of holding members that move toward and away from each other (approach to and move away from each other) are provided, and the outer peripheral surface of the radish is held from below by the movement of the holding members. The operation of the holding member is controlled by an operation control member, and the contacting / separating operation of the holding member is intermittently or continuously changed while keeping the rotation angle position and timing of the holding means. As the operation control member, a plate cam, an end cam, a groove cam, or the like is used, and the holding member has a follower roller for the cam. A pair of left and right inclined surfaces are formed on the inner surface of the holding member of each set, and the radish is held between the pair of inclined surfaces, so that the radish is automatically positioned at the center position of the holding member of each set. I do.

The punching means includes a plurality of sets of cutters and cutter receivers which operate in synchronization with the rotation of the holding means, and a ring-shaped cam for operating the pair of cutters and cutter receivers. They are arranged facing each other on both sides in the direction. The base ends of the cutter and the cutter receiver are slidably connected to a pair of cams. The cutter and the cutter receiver are configured to move toward and away from each other in a processing area corresponding to the rotation position of the holding unit as the cutter and the cutter receiver slide and rotate along the pair of cam surfaces. As a specific example, the opposing interval between the pair of cams is configured to be gradually narrowed partially.

And a mounting plate 22 that stands upright at an angle of 85 °.

The 16 mounting plates 22 are attached at equal intervals in the direction of conveyance of the rotating belt 21, and the spacing between the mounting plates 22 is slightly smaller than the diameter range of the radish R having a different thickness. Set to large. Thus, only one radish R can be mounted on each mounting plate 22. Even if a second radish R is to be mounted, the radish R naturally drops and is removed. It is supposed to be.

A chute 3 extending downward and inclined is provided at an upper position on the carry-out side of the transfer means 2, and the radish R discharged from the transfer means 2 is sequentially dropped on the chute 3 one by one. I have. The lower portion of the chute 3 is formed to be curved in a downwardly protruding arc shape, and its tip is oriented substantially horizontally. A non-slip pattern is formed on the bottom surface of the chute 3 so that the radish R on the chute 3 does not suddenly slide down.

A transfer adjusting member 4 having four radial blade members 41 is provided above a lower end portion of the chute 3.
The transfer adjustment member 4 and the above-mentioned transport means 2 are configured to rotate continuously at a constant speed in synchronization with the motor 6. The transfer adjusting member 4 receives the radish R sliding down on the chute 3 with the blade member 41 and temporarily stops the radish R. The rotation center of the blade member 41 coincides with the center of the arc-shaped portion of the chute 3.

A holding means 5 that rotates about a horizontal rotation shaft 51 is provided below the distal end of the chute 3, and the holding means 5 is driven to rotate by a motor 6. The motor 6 is driven via a timing belt 61 with a gear 62 and the like.
In synchronism with the rotation of the holding means 5, the operations of the transport means 2, the transfer adjusting member 4, and the work-out conveyors 9, 10 described later are synchronously operated.

Radially outwardly of the rotating shaft 51, there are radially attached elastic members 52 fitted to eight vertical cylinders 56, and the elastic members 52 are moved in the extending direction by springs 58 inserted therein. It has been energized. In addition, the elastic member 5
Reference numeral 2 denotes a cam follower roller, and the roller is connected to a plate cam (operation control member) 57. Rotating shaft 51 on plate cam 57
The plate cam 57 expands and contracts at a predetermined timing.
The length of the telescopic member 52 is changed stepwise according to the position of the rotation angle of the holding unit 5 with respect to the angle of 0 ° to 360 ° (the position where the radish R falls from the chute 3 is set to the angle 0 °). ing. That is, the shape of the plate cam 57 has a recess in the range of 90 ° to 135 °, and as a result, the elastic member 52 is most shortened near the angle of 90 ° to 135 °,
Thereafter, the holding means 5 extends as it rotates clockwise.

A pair of Y-shaped opening / closing members 53 are attached to the distal end of the elastic member 52 so as to be openable and closable, and the opening / closing members 53 pivot the base ends of a pair of "H" -shaped bent rods. It consists of wearing The front end of the opening / closing member 53 is slidably fitted to the horizontal cylinder 54, and the horizontal cylinder 54 is disposed at right angles to the telescopic member 52.

A pair of holding members 55 are attached to the distal end of the opening and closing member 53, and the pair of holding members 55 are opened and closed according to the operation of the opening and closing member 53. Accordingly, the opening and closing angles of the pair of holding members 55 are continuously changed according to the angular position of the holding means 5.
That is, the opening degree of the pair of holding members 55 is set to the angle 9 here.
It is set to be the smallest in a (pinching) region of 0 ° to 135 °. Therefore, the radish R is securely held by the holding member 55 near the angle of 90 °, and the radish R is released near the angle of 240 ° to release the radish R.

Here, the radish R by the pair of holding members 55
It is desirable to fix the radish R at the center position of the pair of holding members 55 from the viewpoint of cutting accuracy. As one countermeasure for this, as shown in FIG. 3 or FIG. 4, it is preferable to form a symmetrical inclined surface 55 a or curved surface 55 b on the inner surfaces on the base end side of the pair of holding members 55. With this configuration, when the radish R is placed between the inclined surface 55a or the curved surface 55b, even if the radish R is displaced to one side of the pair of holding members 55 and the radish R is inserted, the radish R is It automatically returns to the center position between the holding members 55 and is held.

The punching means 7 is provided so as to be rotatable integrally with the holding means 5 and includes a plurality of sets of cutters 71 and cutter receivers 72 and pressing rods 76 which are arranged to face each other. An intermediate portion between the cutter 71 and the cutter receiver 72 is provided with support members 73 and 7 disposed on both sides of the holding means 5.
4 supports the holding means 5 so as to be movable in the axial direction and the rotation direction. Further, a pair of cutter ring-shaped groove cams 81 and cutter receiving ring-shaped groove cams 82 are provided outside the support members 73 and 74.
The outer ends of the cutter 71 and the cutter receiver 72 are slidably fitted in 82.

As for the interval between the pair of grooved cams 81 and 82, the interval between the upper portions thereof is a fixed dimension parallel to each other, but the interval between the lower portions is, as shown in FIG. It is getting narrower. As a result, the cutter 71 and the cutter receiver 72 move closer to and away from each other as the lower portions of the groove cams 81 and 82 descend and ascend.

The groove cam 81, the support member 73 and the cutter 71
A play is provided between the fitting portions of the cutter 71 and the cutter 71 to allow a slight movement of the cutter 71 in an oblique direction. Further, a spring (not shown) as an elastic urging means is provided between the cutter 71 and the cutter holding member 75, and the cutter 71 is always elastically attached to the cutter receiver 72 by the spring. It is being rushed. For this reason, even if the cutter 71 approaches the cutter receiver 72 with a slight shift from the oblique direction, the positional shift is favorably absorbed and removed by the spring, so that the entire cutting edge of the cutter 71 is It is designed so that it can adhere to the contact surface.

As shown in FIG. 5, the three-dimensional shape of the cutter 71 is formed in a cylindrical shape, and a plurality of small blades 71a are radially provided on the outer peripheral surface of the cylindrical cutter 71. By using such a cutter 71 with the radial small blade portions 71a, the outer peripheral portion of the radish R is finely divided into fan-shaped small pieces. In this embodiment, the small blade portion 7 is used.
Although four 1a are provided, it is needless to say that the intended purpose can be achieved if the number is two or more.

Next, the operation of the present embodiment will be described. First, a fixed-sized radish R that has been previously cut into a round shape is supplied to the input section 1. The radish R is dropped by its own weight,
It is mounted on the mounting plate 22 of the transport unit 2. In this case, one radish R is sequentially placed on each mounting plate 22, and two or more radishes R are not simultaneously mounted on the mounting plate 22.

The radish R on the mounting plate 22 is carried obliquely upward by the rotation of the rotating belt 21. Next, when the transport direction of the mounting plate 22 changes obliquely downward from the highest position, the radish R falls from the mounting plate 22 onto the chute 3. Then, the radish R slides down along the bottom surface of the chute 3 and contacts the blade member 41 of the transfer adjusting member 4. Accordingly, the downward movement of the radish R is temporarily stopped, and after the stop, the radish R moves according to the rotational displacement of the blade member 41.

Thereafter, the radish R descends toward the lower end of the chute 3 and falls to the holding means 5 outside the lower end of the chute 3. Then, the radish R is held between the pair of holding members 55, and the radish R rotates together with the holding members 55 in the held state. When displaced by a predetermined angle with this rotation, a pair of holding members 5
5 begin to approach each other, and the radish R is eventually securely clamped and fixed by the pair of clamping members 55.

When the holding means 5 further rotates by a predetermined angle, the cutter 71 approaches the cutter receiver 72, whereby the radish R is punched out in the thickness direction, and the pressing rod 76 is pressed.
Is pushed out of the cutter 71 by the. As a result, the radish R is formed into a predetermined shape (that is, a cylindrical shape),
The cut portion on the skin side of the radish R becomes four fan-shaped small pieces. Thereafter, the radish R, which has been processed into a predetermined shape, automatically falls onto the workpiece conveying conveyor 9 by further rotation of the holding means 5. Since the radish after cutting is conveyed in a state in which the molded radish and the fan-shaped small pieces (unnecessary parts) are mixed, it is preferable that the radish is automatically separated by a sieve mechanism or the like that vibrates the radish. preferable.

At the time of cutting, the cutter 71 may approach the cutter receiver 72 in an oblique direction. In this case, the cutter 71 is brought into contact with the cutter receiver 72 by a spring built in the cutter holding member 75. Follow freely. For this reason, the entire periphery of the cutting edge of the cutter 71 is securely brought into close contact with the surface of the cutter receiver 72.
Therefore, the sharpness of the radish R by the cutter 71 is favorably maintained until the end of the cutting process, and the cut end of the radish does not have burrs or chips.

In the punching process using the present apparatus, a large number of radish R are continuously cut, and the cutting efficiency per unit time is dramatically improved as compared with the conventional one. Further, the cutting accuracy was higher than in the case of manual operation, all the radish R was uniformly formed to the standard size, and no defective product was generated.

In this embodiment, since the transport means 2 and the transfer adjusting member 4 are driven by the motor 6 of the holding member 5,
Only one motor 6 needs to be installed as these drive sources, and synchronous operation thereof can be reliably performed.

The present invention is not limited to the above embodiment.
In the embodiment, radish is described as an example of a workpiece, but root vegetables such as ginseng, lotus root, and potato can also be processed in addition to radish. Further, in the above embodiment, the vertical processing device in which the holding member 5 rotates around the horizontal axis has been described. However, the present invention is also applicable to a horizontal processing device in which the holding member 5 rotates around the vertical axis. is there.
