Description

  The present invention relates to a rotational drive force deceleration transmission mechanism in a vegetable slicer. More specifically, the present invention relates to cabbage, carrot, burdock, long onion, onion, cucumber and other vegetables, fruits, mushrooms and other foods (hereinafter “ This is a vegetable slicer for mass-producing sliced processed products of "vegetables", and it relates to a rotational drive force deceleration transmission mechanism that can supply the motor shaft at a reduced speed during its transmission process. is there.

  The present inventor has previously developed a vegetable cutting machine capable of efficiently slicing vegetables with very simple equipment (Patent Document 1: Japanese Patent No. 3817588). In this vegetable cutting machine, a fixed sun gear (18) loosely fitted in a penetrating protrusion of a motor shaft is fixed to a machine frame (1), and a circular rotating disk (25) is attached to the fixed sun gear (18). A round blade having a planetary gear (21) fixed to a motor shaft (17) by a screw (20) and meshing with a fixed sun gear (18) in the hollow rotary plate (19). The rotating shaft (22) of (26) is provided (see FIGS. 5 and 6).

  In this conventional vegetable cutting machine, a hollow rotating disk (19) fixed to a motor shaft (17) with a screw (20) and a circular rotating disk (25) attached thereto are provided as a motor shaft (17). It is directly driven by rotation. Then, as the hollow rotary disk (19) rotates, the rotary shaft (22) of the round blade tries to revolve around the motor shaft (17), and the planetary gear ( 21) is engaged with the fixed sun gear (18), so that the round blade (26) rotates at a high speed in accordance with its revolving operation, and the vegetables are removed in the gap with the circular rotating disk (25) rotating at a low speed. Slice.

  Thus, in the case of the conventional vegetable cutting machine, the motor shaft (17) is pivotally supported by the hollow turntable (19), the circular turntable (25), and the hollow turntable (19), which are directly connected thereto. The rotary shaft (22) of the round blade is directly driven to rotate, and the disk-shaped rotary blade (16) is indirectly rotated at high speed (from the relationship between the fixed sun gear (18) and the planetary gear (21) meshing with the fixed sun gear (18)). It is necessary to use a relatively expensive geared motor as the motor because it is driven (rotation).

Japanese Patent No. 3817588

  As described above, in the case of the conventional vegetable cutting machine, a hollow rotating disk and a circular rotating disk attached to the motor shaft are directly driven to rotate, and a relatively expensive geared motor is used as the motor. Since it is necessary to use it, the cost was increased accordingly. Therefore, the present invention enables the rotation of the motor shaft to be transmitted while decelerating in the transmission process without using a geared motor, and thus the rotational drive in the vegetable slicer that can improve cost effectiveness. It is an object to provide a force deceleration transmission mechanism.

  In order to solve the above-mentioned problem, the invention according to claim 1 is to face the circular opening with an appropriate gap between the rotating substrate eccentrically provided with the circular opening and the inner edge of the circular opening. A rotary blade in a vegetable slicer that slices the input vegetables into a thickness corresponding to the gap when the round blade rotates and revolves. A mechanism that is installed in a motor housing and through which a drive shaft of the motor is inserted; a bearing that is provided between the shaft cylinder and the shaft, and the drive shaft; A rotating case that is pivotally supported by the shaft cylinder and the drive shaft via a bearing disposed between the tip of the shaft and a fixed sun that is fixedly installed at the tip of the shaft cylinder facing the rotating case In the rotating case Rotation transmission means disposed between the drive shaft and the rotation shaft of the round blade pivotally supported at the edge of the rotation case, and a planetary gear that is attached to the rotation shaft and meshes with the fixed sun gear. The rotation transmission means is a rotational drive force reduction transmission mechanism in a vegetable slicer, which is one of a combination of a belt and a pulley, a combination of a drive gear and a driven gear, and a combination of a chain and a sprocket.

  The present invention is as described above, and in the case of the mechanism according to the present invention, the rotation of the driving shaft of the motor does not directly act on the rotating case that supports the rotating substrate that rotates at a low speed. The planetary gear is transmitted along the fixed sun gear from the relationship between the planetary gear that is transmitted to the rotation shaft via the rotation transmission means arranged between the rotation shaft and the planetary gear that is attached to the rotation shaft, and the fixed sun gear that meshes with the planetary gear. It rotates while revolving, and the rotating case is driven to rotate as the planetary gear revolves. Therefore, since the rotation of the rotating case is decelerated from the rotation of the drive shaft in the transmission process, the mechanism according to the present invention can be configured without using a relatively expensive geared motor. There is an effect that it is possible to improve cost effectiveness.

It is a perspective view which shows the structure of the conventional vegetable cutting machine. It is a longitudinal cross-sectional view which shows the structure of the conventional vegetable cutting machine.

  A mode for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall perspective view of a vegetable slicer incorporating a rotational driving force deceleration transmission mechanism according to the present invention, and FIG. 2 is an exploded perspective view thereof. As shown there, the present slicer is composed of a main body 2 supported by the stand 1 and an outer cover 3 that is detachably attached to the main body 2. A feeding unit 4 for feeding and a feeding unit 5 for feeding processed sliced products are provided. The exterior cover 3 can be attached to and detached from the main body 2 by tightening or loosening the fixing screw 8.

  The main body 2 holds a gap 13 at an appropriate interval between the motor housing 10 that houses the blade driving motor 10 a, the rotating substrate 11 that is eccentrically provided with the circular opening 12, and the inner edge of the circular opening 12. The rotary blade 14 disposed so as to face the circular opening 12, and the rotary substrate 11 and the rotary case 16 that supports the round blade 14, and the rotational driving force deceleration transmission according to the present invention is provided in the rotary case 16. A mechanism is incorporated. The rotating substrate 11 is attached to the rotating case 16 with several supporting shafts 17 fixed on the back surface thereof supported by a shaft supporting portion 18 provided on the side surface of the rotating case 16.

  The drive shaft 21 extending from the motor 10a is inserted into the shaft cylinder 15 provided on the end face of the motor housing 10 and faces the rotary case 16 (see FIG. 4). Bearings 22 and 23 are provided on both side surfaces of the rotating case 16, the shaft cylinder 15 is fitted into the bearing 22 installed on the side surface on the motor housing 10 side, and the tip of the drive shaft 21 is fitted into the other bearing 23. It is. Thus, the rotary case 16 is rotatably supported by the shaft cylinder 15 and the drive shaft 21, but the rotation of the drive shaft 21 is not directly transmitted to the rotary case 16 as will be described later.

  Bearings 24 and 25 are provided on both sides of the edge of the rotating case 16, and the rotation shaft of the round blade 14 is pivotally supported by these bearings 24 and 25. The round blade 14 is fixed to the outer end portion of the rotation shaft 19 protruding from the rotating case 16.

  As a means for transmitting rotation from the drive shaft 21 to the rotation shaft 19 in the mechanism according to the present invention, a combination of a belt and a pulley, a combination of a drive gear and a driven gear, or a combination of a chain and a sprocket can be considered. The illustrated example is a combination of a belt and a pulley. In that case, a toothed belt 28 that is difficult to slip is preferably used as the belt, and toothed pulleys 26 and 27 are used as the pulleys.

  One toothed pulley 26 is installed at the tip of the drive shaft 21 protruding from the shaft cylinder 15 in the rotary case 6, and the other toothed pulley 27 is installed on the rotation shaft 19 of the round blade 14. A toothed belt 28 is wound around the toothed pulley 26 and the toothed pulley 27. The rotation shaft 19 can be driven to rotate at the same speed as the rotation speed of the drive shaft 21, or at a low speed or a high speed by adjusting the number of teeth of the toothed pulley 26 and the toothed pulley 27.

  When a combination of a drive gear and a driven gear is used, a drive gear is installed on the drive shaft 21 in the rotating case 16, and a driven gear that meshes with the drive gear is installed on the rotation shaft 19. Also in this case, the rotation of the drive shaft 21 can be shifted and transmitted to the rotation shaft 19 by adjusting the number of teeth of the drive gear and the driven gear. The same applies when a combination of a chain and a sprocket is used.

  A fixed sun gear 30 is fixedly installed at the tip of the shaft cylinder 15 extending into the rotary case 16. A planetary gear 31 that meshes with the fixed sun gear 30 is attached to the rotation shaft 19.

  When the motor 10a is operated in the above-described configuration, the rotation of the drive shaft 21 is transmitted to the rotation shaft 19 via the toothed pulleys 26 and 27 and the toothed belt 28, and of course, the bearing 23 It is not directly transmitted to the rotating case 16 that is in contact with the rotary case 16. When the rotation of the drive shaft 21 is transmitted to the rotation shaft 19, the rotation shaft 19 tries to rotate, and the planetary gear 31 attached thereto acts to rotate the fixed sun gear 30 with which the rotation is engaged. However, since the fixed sun gear 30 is fixed to the shaft cylinder 15 and does not rotate, as a result, the planetary gear 31 revolves along the fixed sun gear 30 while rotating.

  As a result of the revolution of the rotating shaft 19 in this way, the rotating case 16 that supports the rotating shaft 19 via the bearings 24 and 25 rotates around the drive shaft 21 (shaft cylinder 15). The rotation is considerably decelerated with respect to the rotational speed of the drive shaft 21. In addition, the rotating substrate 11 integrated into the rotating case via the support shaft 17 and the shaft support portion 18 is also decelerated and rotated about the drive shaft 21 (shaft cylinder 15). Thus, the round blade 14 installed on the rotation shaft 19 revolves along the fixed sun gear 30 and revolves at high speed in the same direction as the revolving direction, continuously feeding the vegetables to be introduced. The slice is sliced to a thickness corresponding to the gap 13.

  Although the present invention has been described in some detail with its most preferred embodiments, it will be apparent that further embodiments may be constructed without departing from the spirit and scope of the invention. Accordingly, the invention is not limited to that particular embodiment, except as limited in the appended claims.
