Abstract

PURPOSE:To disable closing of a cover and operation of a juicer and prevent a device from damaging when a holding tool is incompletely mounted, by providing a special fixture on a fruit holding tool of the juicer. CONSTITUTION:A pin 16 is provided in a fruit holding tool 6 of a juicer and one end of a fixture 20 is rotatably pivoted thereon. A spring 12 is provided for urging the other end of the fixture 20 to jump up. A screw 15 for screwing in an arm 5 is provided at the other end of the fixture 20. When the screw is incompletely engaged with the arm 5, the fixture 20 jumps up by rebounding force of the spring 21. Thereby a cover of the juicer cannot be closed and the juicer cannot be operated.

Description

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

BACKGROUND OF THE INVENTION A conventional holder mounting portion of this type of juicer has a structure as shown in FIGS. 4 to 6. That is, the holder 3o includes a mounting bracket 33 that is supported by a pin 31 and has a hole 32, and a spring 34 that biases the mounting bracket 33.
and a cylindrical fitting hole 36 into which the arm 36 fits, while the cylindrical arm 36 engages with the hole 32 of the mounting bracket 33 to firmly secure the holder 30 to the arm 36. It was equipped with a fixing pin 37 for fixing to. In addition, 38
39 is the slide pin 3 that slides on the arm 36 by a cam mechanism (not shown);
A coil spring 40 resists the pop-out movement of 8, and a coil spring 40 is opened and closed by the movement of the slide pin 38 to hold fruits, etc. in the holder 3o.
A pair of pawls 41 which are held in place or ejected from the holder 3o are leaf springs that exert a spring force during opening movement against the closing movement of the pair of pawls 4o.

Problems to be Solved by the Invention However, such a conventional configuration has the following problems. That is, since this juicer is a commercial device, the users of this device are often women who work part-time or the like, and are not necessarily familiar with the device. For this purpose, for example, the arm 36 of the holder 30
If you do not fully insert and install the mounting bracket 3
The operation was often carried out in a state where the fixing pin 37 of the arm 36 was not engaged with the hole 32 of the arm 36. If operation is carried out in such a state, the rotating holder 3o will pop out when the slide pin 38 moves, and as a result, only the tip of the arm 35 will fit into the fitting hole 36 of the holder 3°. Holding tool 3o rotates until its tip 30&
comes into contact with the peripheral side surface 42 of the main body, and as a result, this leads to damage to the main body or the entire device.

An object of the present invention is to provide a juicer that solves these problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a fruit holder that is rotatably supported at one end and detachably provided at the tip of the arm, and at the other end. The arm is equipped with a fixture with a fixing screw that engages and fixes the arm, and when the fixing screw is released, the other end of the fixture operates a safety switch when closed, and the electric motor is activated. It is biased by a spring so as to prevent the closing operation of the cover that supplies electricity to the cover.

Effect: According to the above structure, when the fruit holder is inserted into the arm, it is inserted and fixed securely. In other words, if the fixing screw provided at the other end of the fixture is not fixed by engaging with the screw hole of the arm, the fixture will be in an open state and in contact with the cover, so the cover will not close. This cover engages with the safety switch to operate the safety switch, and unless this cover is closed, the safety switch will not turn on, and as a result, the equipment cannot be operated. In other words, since the device cannot be operated unless the user inserts the holder securely, damage to the device can be reliably prevented without relying on intuition.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In Figures 1 to 3, 1 is the main body, and this main body 1
An electric motor 2 and a speed reduction mechanism section 3 are built in. On both sides of the main body 1 are rotatably driven by the electric motor 2,
A pair of cam mechanism parts 4 are provided in a protruding manner, and a fruit holder e is detachably provided on an arm 6 that protrudes from the cam mechanism part 4. On the trajectory of the side surface of the main body 1 along which the holder 6 rotates, there is provided a squeeze cone 7 which is rotationally driven by the electric motor 2 and which squeezes the fruit. 8 is a cover that covers the side and top surfaces of the main body 1;
9 is an input port into which fruits are input. Further, a cutter 10 for cutting the fruit in half is provided above the main body 1.

The holder 6 is supported by a pin 11 and includes a mounting bracket 13 having a hole 12, a spring 14 that biases the mounting bracket 13, and a cylindrical fitting hole 6+L that fits into the arm 6.
It is equipped with On the other hand, the arm 6 is provided with a fixing pin 16 that engages with the hole 12 of the mounting fitting 13 to fix the holder 6 to the arm 6 and has a screw hole 162L at its tip. The holder e has one end mounted on the pin 16 and rotatably supported, and the other end provided with a screw hole 161 of the fixing pin 15.
Fixing screw 17 for engaging and fixing the L part with washer 18
It is provided with a fitting 20 which is rotatably fixed with a hexagonal nut 19 via a hexagonal nut 19. A kick spring 21 applies force to the fixture 2o to keep it open at all times, and when the fixing screw 17 is released, the fixture 20 opens to the vicinity of A due to the biasing force of the kick spring 21, and the other end is attached to the cover 8. and prevents the cover 8 from closing. This cover 8 is in contact with a safety switch 22, and when the cover 8 is closed, the safety switch 22 is turned on and operation becomes possible.
It becomes inoperable when it is opened. A safety cap 23 is press-fitted and fixed to the other end of the fixture 2o that comes into contact with the cover 8, and is intended to prevent the cover 8 from being damaged.

24 is a slide bin that slides on the arm 6 by the cam mechanism 4; 25 is a coil spring; and 26 is opened and closed by the movement of the slide bin 24 to hold fruits etc. in the holder 6; A pair of pawls 27 for discharging more are leaf springs that exert a spring force during opening movement against the closing movement of the pair of pawls 26.

The operation of the above configuration will be explained next.

First, when a user puts a whole fruit such as an orange into the input port 9, the fruit is transferred to the cutter 1 by the rotational movement of the holder 6.
After being pushed toward 0 and cut in half, it is held in the holder 6 by the action of the pair of claws 2e.

When the holder 6 reaches the position of the aperture cone 7, the inner surface of the holder 6 moves to be pressed against the aperture cone 7 by the cam mechanism 4, thereby being squeezed. The holder 6 is removable from the arm 5 due to the need for cleaning. When inserting and setting the holder 6 into the arm 6, insert the holder 6 into the arm 6 all the way and attach it to the mounting bracket. What is necessary is just to engage the hole 12 of 13 and the fixing bottle 15, and just to fix it. If this insertion is only completed halfway, that is, if the insertion set is incomplete, fixing screw 17
cannot be screwed into the screw hole 151L. Therefore, the user easily notices that the insert set is incomplete. Also, if you forget to screw in the fixing screw 17, the cover 8 will not close even if you try to operate it.
The safety switch 22 cannot be turned on and therefore
The user notices this because the operation has not started.

Effects of the Invention As is clear from the description of the embodiments above, in the juicer of the present invention, if the holder is not fully inserted, the cover will not close and the device will not be able to operate. This makes it possible to completely prevent damage to the equipment even if it is used by a user who is not familiar with the equipment, such as a part-time worker.
