Description

Feed automatic feeding device {automatic meal service apparatus}

The present invention relates to a feed automatic feeding apparatus, and more particularly to a feed automatic feeding apparatus that is simple in structure and can easily adjust the desired feeding amount.

In recent years, as economic conditions improve and nuclear family development proceeds, the number of people who consider pets as family or self-employment is increasing. And, reflecting this trend, the sales of pets, especially dogs, grooming, treatment or prevention of infectious diseases or feed manufacturing industry is in a successful situation.

Thus, as pets take a large part in each individual's life, it is necessary to feed the pet regularly or on a timely basis, especially for long-term outings due to vacations or business trips while leaving the pet alone at home. Feeding is a big problem if you have to. In order to solve such a problem, a device for automatically feeding food at a predetermined time has been proposed in Utility Model Registration No. 173567 with the designation "Feed feeder".

1 is a schematic longitudinal sectional view of a conventional automatic feeder, Figure 2 is a perspective view showing the internal configuration of the conventional automatic feeder shown in Figure 1, Figures 3a and 3b are respectively shown in Figure 1 It is a cross-sectional view for explaining the operation state of the main part before feeding and at the time of feeding in the automatic feeding device of the feed. As shown in Figures 1 to 3, the conventional automatic feed device is a feed is contained in the inside of the feeder box 1, the lower portion is provided with a feed portion 2 is provided with an inclined guide plate (2a), feed feeder In the middle of the box 1, the feed container 5 is coupled on the movement guide plate 3 so as to be linearly movable. The feed container (5) containing a predetermined amount of feed is advanced by the drive unit (4), the drive unit (4) is a deceleration motor (4a) is fixed to the middle of the feeder box 1, this deceleration The driving force of the motor 4a is transmitted to the feed container 5 by the crank mechanism 4h which consists of the rotation disk 4c which has an eccentric shaft, and the lever member 4f, and makes the feed container 5 reciprocate. do.

On the other hand, the movable opening and closing plate 5b is coupled to the bottom of the feed container 5a of the feed container 5 by a hinge 5c, and the lower opening of the inclined guide plate 2a is behind the feed container 5. A fixed opening and closing plate 5e for opening and closing the door is provided. In the front part of the feed container (5) is formed a discharge guide (3a) for guiding the feed pouring from the feed container (5), the discharge port (8) for discharging the feed in the lower front of the feeder box (1) Is formed. In the figure, reference numeral 6 denotes a wheel 6 for reducing friction when the feed container 5 is moved back and forth, and 11 and 4d respectively indicate a stop switch for detecting a stop position and a push protrusion for operating the same.

In the conventional feed automatic feeding device having the above-described configuration, when the time set by the user (timer) (not shown) arrives, as shown in FIG. 3B, the speed reduction motor (with a feed contained in the feed container 5) The feed container 5 is advanced by rotating the shaft of 4a) and operating the crank mechanism 4h. When the feed container 5 is advanced in this manner, the restraint of the movable opening and closing plate 5b which is blocking the bottom of the feed container 5 is released, and the movable opening and closing plate 5b is suspended on the hinge 5c. Aside from the bottom, as shown in FIG. 3A, the feed contained in the feed container 5 is sequentially placed in the dish 9 through the discharge guide 3a and the discharge port 8.

Hereinafter, a description will be given of the operation of the automatic feed device of the present invention, it is assumed that the feeding time and meal time is set in advance by the user, the power is always supplied. First, when the next feeding time does not arrive at the end of the meal time, as shown in FIG. 6B, the dish transport drawer 120 and, as a result, the tableware 130 containing the food are stored in the main housing 100. It will remain In this state, when the feeding time is reached or the arbitrary advance button 280 is pressed, the control unit 200 recognizes this and outputs a control signal to the motor forward / reverse drive unit 260 to operate the deceleration motor 262. Let's do it. As the deceleration motor 262 operates as described above, the rotating shaft 141a rotates in the clockwise direction in the direction of the arrow in FIG. 6A, and in connection with this, the drive link 142 and the driven link 143 operate to operate the dish transport drawer. 120 is advanced. As such, when the push pin of the forward position detecting switch 147 is pressed by the drive link 142 as shown in FIG. 6B while the forwarding of the dish transport drawer 120 continues, the corresponding forward position detecting signal is controlled. The controller 200 stops the operation of the deceleration motor 262 by giving a stop command to the motor forward / reverse driving unit 260. In this process, the discharge of the feed through the feed outlet 114a is prevented by the feed discharge preventing plate 126.

On the other hand, when the preset meal time elapses or the random advance button 280 is pressed while the tableware 130 is exposed, the control unit 200 recognizes this and outputs a control signal to the motor forward / reverse driving unit 260. To operate the reduction motor 262. As the deceleration motor 262 operates as described above, the rotary shaft 141a rotates in the counterclockwise direction, which is the arrow direction in FIG. 6B, and in connection with this, the driving link 142 and the driven link 143 operate to move the dishes. Drawer 120 is retracted. As described above, when the push pin of the retracted position detecting switch 148 is pressed by the drive link 142 while the retracting of the dish carrying drawer 120 continues, the corresponding retracted position detecting signal is controlled by the controller ( 200, the control unit 200 stops the operation of the deceleration motor 260 by giving a stop command to the motor forward / reverse driving unit 260. In this state, since the tableware 130 is placed directly below the feed outlet 114a, the feed of the volume is poured into the tableware to prepare for the next meal.

The feed automatic feeding device of the present invention is not limited to the above-described embodiment and may be implemented in various modifications within the range allowed by the technical idea of the present invention. For example, in FIG. 7, the electric configuration of the automatic feed device of the present invention is described as being controlled by a program, but is not limited thereto, and may be implemented by pure hardware technology. In addition, the drawer retracting mechanism may be embodied in the manner mentioned in the related art, rack and pinion, or other methods in addition to the two-stage link mentioned in the above-described embodiment.

According to the feed automatic feeding device of the present invention as described above, since the feed is accurately discharged to the tableware by forming the body with the device, the feed is not scattered on the floor, and the overall structure of the device is simple. This reduces the volume of the device and reduces manufacturing costs. Another advantage of this arrangement is that the tableware can be formed into a unit with the device, thereby contributing to the health of the pet by limiting the meal time (the time the table is exposed) to a desired time zone so that regular meals can be made. It is possible to prevent harmful insects such as flies or mosquitoes from swelling because the food left after eating is not exposed to the outside for a long time.

In addition, since the tableware is exposed to the outside of the main body housing while being mounted in the dish storage container, the tableware having a volume suitable for the feeding amount can be easily replaced.
