FIG. 1 is a side sectional view of a food and drink discharging device provided in a food and drink supply device according to an embodiment of the present invention, FIG. 2 is a plan view thereof, and FIG. 3 is a front view thereof. Note that FIG.
In 2 and 3, the same reference numerals as those in FIG. 5 represent the same or corresponding portions.

In FIGS. 1, 2 and 3, 4 A is a food and drink discharging device, and 12 is arranged on one side of the discharging tube 3 which is held in a linearly extended state as described later, and It is an endless transfer member such as a chain, a belt or a caterpillar having a plurality of rotating rollers 8 for pressing the discharge tube 3, and the transfer member 12 is provided between a pair of upper and lower drive gears 13a and a driven gear 13b. It is supposed to be stretched over. Here, the drive gear 13a and
The driven gear 13b is a pair of drive wheel and driven wheel in the present invention.
If the transfer member is, for example, the above-mentioned belt,
Consists of a pair of drive pulley (belt wheel) and driven pulley
It goes without saying that it will be done. By thus extending the transfer member 12 between the pair of gears 13a and 13b, the transfer member 12 performs a circular motion including a linear track portion. In addition, 8a is a rotating shaft of the rotating roller 8.

Reference numeral 14 is a motor that rotates for a certain period of time when the supply switch 2b (see FIG. 4) is pressed, and the rotation of this motor 14 is applied to the rotary shaft 16 of the lower drive gear 13a via the reduction gear device 15. The drive gear 13a is rotated counterclockwise as indicated by the arrow. The rotation of the drive gear 13a causes the transfer member 12 to make a circular motion including a linear orbital portion, and the rotary roller 8 linearly moves and discharges the discharge tube 3 while pressing the discharge tube 3 accordingly. A required amount of food and drink is discharged from the tip of the tube 3 for food.

On the other hand, 17 is a guide pivotally supported on the front surface of the main body 2 which is one side facing the rotary roller 8 so as to be openable and closable in the front-rear direction. The discharge tube 3 is opened forward when it is attached to the main body 2, and is closed after the discharge tube 3 is linearly extended downward to the main body 2, and the discharge tube 3 is closed.
This is for pressing the discharge tube 3 by the rotating roller 8 in this state.

Here, the discharge tube 3 of the guide 17
The back surface corresponding to is formed into a linear wall surface. By thus forming the back surface into a linear wall surface, the rotary roller 8 that moves linearly while the discharge tube 3 is pressed.
The discharge tube 3 extending linearly can always be pressed with a uniform force. 1
8 is a hook portion provided at the moving end of the guide 17,
By engaging the hook portion 18 with the main body 2, the guide 17 can sandwich the discharge tube 3.

By the way, in the case where the discharge tube 3 is sandwiched between the guide 17 and the rotating roller 8 as described above, when the rotating roller 8 presses the discharging tube 3 during the linear movement, the discharging tube 3 is attached to the rotating roller 8. Repulsive force from 3 will be added. Here, the part of the transfer member 12 to which the rotary roller 8 is attached is a pair of upper and lower gears 13a,
When in contact with 13b, even if such a repulsive force is applied, the rotary roller 8 is supported by the gears 13a and 13b and is not pushed backward.

However, when the portion of the transfer member 12 to which the rotary roller 8 is attached no longer contacts the pair of upper and lower gears 13a and 13b, the rotary roller 8 is pushed backward by the repulsive force from the discharge tube 3 and is discharged. It becomes impossible to always press with a uniform force.

Therefore, on the other side of the rotary roller 8,
Gear 13a, the portion that is not supported at 13b in response to the straight track portions of the transfer member 12, while pressing the discharge tube 3 without rotating the roller 8 to linear motion is pushed rearward guide 17 and the flat line Mr. A guide portion 19 for guiding the vehicle to travel is provided. In this embodiment, the guide portion 19 is attached to the rotating shafts 16 and 16a of the pair of upper and lower gears 13a and 13b.

Further, in this embodiment, the rotary roller 8
2, a holding recess 20 for receiving and holding the discharge tube 3 is formed, and when the discharge tube 3 is set, the holding recess 20 is discharged along the holding recess 20. I am trying to set the tube 3. Then, by setting the discharge tube 3 along the holding recess 20 in this manner, the discharge tube 3 is guided by the guide 1.
The movement of the discharge tube 3 in the axial direction can be regulated so that the discharge tube 3 is not pinched between the rotary roller 8 and the rotary roller 8.

Next, the supply of food and drink in the food and drink supply device thus configured will be described.

After the BIB1 is set on the main body 2, the BIB is
While taking out the discharge tube 3 from the bottom of 1, the hook 17 is removed from the main body 2 and the guide 17 is opened, and then the discharge tube 3 is linearly moved downward along the holding recess 20 of the rotary roller 8. extend. Then, after the tip of the discharge tube 3 is made to project to the upper part of the food and drink outlet 5 provided in the lower portion of the guide 17, the guide 17 is closed and the hook portion 19 is locked to the main body 2. As a result, the discharge tube 3 is sandwiched between the linear wall surface of the guide 17 and the rotary roller 8 while being extended linearly downward.

After that, when the supply switch 2b is pressed, the motor 14 rotates for a certain period of time, and the rotation of the motor 14 is transmitted to the rotary shaft 16 of the lower drive gear 13a via the reduction gear device 15 to drive the drive gear 13a. It rotates counterclockwise as shown by the arrow in FIG. Here, when the drive gear 13a rotates in this manner, the transfer member 12 makes a circular motion including a linear orbital portion, and accordingly, the rotary roller 8 linearly moves while pressing the discharge tube 3.

When the rotary roller 8 linearly moves while pressing the discharge tube 3 in this manner, a required amount of food and drink is discharged from the tip of the discharge tube 3 toward the lower container. When the discharge tube 3 is pressed, the repulsive force from the discharge tube 3 is applied to the rotating roller 8, but the rotating roller 8 is supported by the pair of upper and lower gears 13a and 13b and the guide portion 19, and therefore is pushed backward. There is no.

When the discharge tube 3 is set, if the discharge tube 3 is not properly set, the linear movement of the rotary roller 8 causes the discharge tube 3 to shift in the axial direction. As shown in FIG. 2, a holding recess 20 that restricts the movement of the discharge tube 3 in the axial direction is formed in the guide tube.
And the rotary roller 8 are not sandwiched.

As described above, by causing the rotating roller 8 to perform the revolving motion including the linear orbital portion by the transfer member 12, the rotating roller 8 linearly moves while pressing the side portion of the discharge tube 3. Because it is possible to discharge tube 3
Can be held in a linearly extended state. Further, a guide 17 is provided on one side facing the rotating roller 8 so as to be openable and closable, and the discharge tube 3 is connected to the guide 17 and the transfer member 12.
It can be pressed by the rotating roller 8 in a state of being sandwiched by the linear track portion of the.

Furthermore, by providing the guide portion 19 opposite the straight trajectory part of the transfer member 12, the rotating roller 8 discharge tube 3 while pressing can travel in a flat line with the guide 17. Further, by forming the holding recess 20 in the rotating roller 8, the movement of the discharge tube 3 in the axial direction of the rotating roller 8 can be restricted.
