Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a juicer for commercial use.

BACKGROUND OF THE INVENTION Conventionally, there has been a juicer in which a holder holding a fruit rotates on the side surface of a main body, and a squeeze cone is provided along the rotation locus of the holder (for example, Japanese Patent Publication No. 44-6605). This configuration is shown in FIGS. 6 to 8.

The holder 1 of the juicer is a pawl by a leaf spring 2; 64, which operates the pawl 3, is a support pin for the pawl 3.

Problems to be Solved by the Invention However, if the leaf spring 2 is as shown in the drawing, the claws 3 close around the support pin 4 in order to hold the fruit in the holder 1 as the slide pin 5 rises. At the end, claw 3 until halfway
However, in the latter half, the point of action 2 with claw 3
a had slipped, and the resistance force of the leaf spring 2 trying to release the claw 3 was weak. As a result, the claws 3 do not release normally when the outer skin of the fruit is discharged after the fruit has been squeezed, resulting in a discharge error. In addition, when the pawl 3 opens and closes, the pawl 3 can move on the support pin 4, so the side surface 2b of the temporary spring 2 rubs against the holding '1.1 (aluminum casting +!!2) and aluminum powder is generated. It was supposed to be mixed into the fruit/1.

The present invention is intended to solve these problems, and aims to prevent the fruit rind from being erroneously discharged and to prevent the leaf spring from rubbing against the holder.

Means for Solving the Problems In order to solve this problem, the present invention provides a main body incorporating an electric motor and a speed reduction mechanism, a cam mechanism portion protruding from approximately the center on both sides of the main body, and the cam mechanism portion. a fruit holder that rotates on the side surface of the main body while engaging with the main body, and a cutter provided on the main body rim.

A squeeze cone is provided on both sides of the main body on the rotation locus of the holder, a pawl provided on the holder for holding the fruit, and a leaf spring for releasing the pawl by the cam mechanism. A sleeve is provided on a support pin that supports the movement of the pawl, with the pawl interposed therebetween.

Effect: With this configuration, when the pawl closes, the resistance acting portion of the leaf spring is locked by the sleeve and does not move. or,
Since the movement of the claws on the support pins can be restricted, contact between the leaf spring and the holder can be prevented.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings. In FIGS. 1 to 5, 11 is a main body, and an electric motor and a speed reducer are installed inside the main body.

The rotation of the fu 1iIJ machine is decelerated, and the pair of aperture cones 12 and the pair of holders 14 are connected via the cam mechanism section 13.
is transmitted to. The cam mechanism section 13 includes a fixed cylindrical cam 1
5, and a cam follower 17 that engages with the cam follower 17 to perform four swing movements during rotational operation due to the rotation of the turret 16.
and the engagement with the groove 15a of the cylindrical cam 15 and the coil spring 18.
It consists of a slide pin 19 that performs a sliding movement by
A holder 14 is provided at the tip of the cam follower 17.

The cam mechanism part 13 protrudes from substantially the center of both sides of the main body 11, the holder 14 rotates on the side surface of the main body 11, and the aperture cone 12 is provided on the rotation locus of the holder 14. There is. The support pin 20 is fixed to the holder 14, and the slide pin 19 is supported by the support pin 20.
A claw 21 is provided which closes by the sliding movement of the claw 2.
Sleeve 22 crimped to support pin 20 on both sides of 1
The pawl 21 is subjected to a resistance force by the leaf spring 23 to try to release the pawl 21. 24 is a transparent cover that can be attached to and detached from the main body 11 to prevent fruit juice from scattering.

It also forms a fruit inlet 24a. 25 serves to filter and store the juice squeezed by the fruit juice receptor. Further, a cutter 26 is provided in the F section of the main body 11, which is positioned substantially on the central plane of the pair of holders 14 and cuts the fruit in half.

Next, the operation of the configuration of this embodiment will be explained. When the power switch is turned on, the aperture cone 12 and the holder 14 begin to rotate. Next, add the whole fruit (e.g. orange) D
When inserted from 24a, the fruit is pushed by a pair of rotating holders 14 and cut in half by a cutter 26. The fruit enters into the holder 14 by the swinging motion during the rotation of the cam follower 17, and then the slide pin 19 It rises due to the cam groove 15a and attempts to close the pawl 21. As a result, the leaf spring 23 becomes arched, creating a drag force. At this time, since the leaf spring 23 is in contact with the sleeve 22 from the beginning, the point of action 2 of the resistance force of the leaf spring 23 against the claw 21 during the closing movement of the claw 21 is
3a does not move. Therefore, the maximum resistance occurs when the claw 21 completes its closing movement. Then, further holder 1
4 rotates, and squeezes the fruit juice by swinging the fruit held on the rotation locus and pressing the fruit held against the rotating cone I2. Then, the rotary movement is further continued while the outer skin of the fruit is held, and the slide pin 19 is lowered by the coil spring 18 in a substantially horizontal position, the claw 21 is released, and the outer skin of the fruit that was being held is removed. The outer skin passes through the outer skin discharge port 11a and is discharged into a trash can placed at the bottom of the main body 11. or,
The claws 21 provided on the holder 14 are prevented from moving on the support pin 2o by sleeves 22 on both sides. Therefore, the side surface 23b of the leaf spring 23 does not come into contact with the holder 14.

Effects of the Invention According to the present invention, by inserting the sleeve into the support pin provided on the holder with the claw between them, the release force of the claw within the holder is increased, and the error in ejecting the fruit rind can be avoided. prevent,
Furthermore, rubbing between the leaf spring and the holder can be prevented.
