[0001]

The present invention relates to a vibration feeder.
More specifically, the present invention relates to a food vibrating feeder for supplying a relatively small amount of solid food at a constant rate.

[0002]

2. Description of the Related Art In the food processing industry, for example, relatively small solid foods (hereinafter simply referred to as "foods") such as fruits such as cherries or corn, or carrots, potatoes, and cut meats that have been diced. ) Must be supplied in fixed amounts. Conventionally, such a metered supply is V
It was performed by a letter-shaped trough or a combination weigher. However, in the V-shaped trough, unevenness is formed in the layer thickness of the food on the trough when piled up, and the unevenness cannot be sufficiently uniformized by vibration. However, there has been a problem that the non-uniformity is not uniform. In addition, the combination weigher has a problem that the accuracy is high but the mechanism is complicated, cleaning and the like are troublesome and expensive. Therefore, there has been a demand for a device having a simple mechanism and capable of stably supplying a relatively small amount of solid food in a predetermined amount.

[0003] In order to satisfy such demands, devices for supplying individual components one by one have been known in the field of handling electrical components. For example, Japanese Patent Application Laid-Open No. 55-111310 discloses a component feeder in which a trough is attached to a vibrating section of a straight-ahead feeder, and a work accumulation wall in which vibration from the vibrating section is cut off on both sides of the trough. . However, in such an apparatus, since both the trough and the work storage wall are attached to the vibrating portion of the straight feeder, it is necessary to vibrate both the trough and the work storage wall and the entire product stored on the work storage wall. was there. Therefore, in order to apply such an apparatus to the above-mentioned food, since such food is relatively flexible and has a property of absorbing vibration, a large vibration, for example, about 3 mm, must be given to the linear feeder. I had to. Therefore, there is a problem that the work accumulation wall cannot absorb such a large vibration and cannot substantially block the vibration.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and provides an apparatus which has a simple mechanism and is capable of stably supplying a relatively small amount of solid food in a fixed amount. It is the purpose.

[0005]

According to the present invention, a fixed plate is provided on an upper portion, and a vibration trough is provided below and below the fixed plate.
A vibrating feeder having a substantially V-shaped vertical cross section, wherein the fixed plate is constituted by two flat plates arranged substantially in parallel with their lower ends opened upward with a space therebetween; Is disposed along the lower end of the fixed plate, has a lateral dimension larger than at least the interval between the lower ends of the fixed plate, and is inclined horizontally or downward in the supply direction of the vibrating feeder. A vibrating feeder for food, characterized in that:

The present invention is also characterized in that the vibrating trough has an extension extending outward in the supply direction of the fixed plate.

[0007]

According to the above construction, since the fixed plate and the vibrating trough are separately provided, even if the vibrating trough is given a large enough vibration to move the food, the vibration of the food held on the fixed plate is reduced. Is deterred. Thereby, the food between the lower end of the fixed plate and the upper surface of the vibration trough among the foods stored in the fixed plate is moved along the vibration trough directly under the influence of the vibration trough, and is moved above the lower end of the fixed plate. Certain foods are not affected by vibration and tend to stay in position on the fixed plate. Therefore, a fixed height boundary is formed near the lower end of the fixed plate,
Only food of a certain thickness on the vibrating trough can be moved. Further, since only the vibration trough is vibrated, a large amplitude can be generated, and the present invention can be applied to a soft solid food which is easily sticked. Thereby, a predetermined amount of food can be stably supplied by adjusting the layer thickness and the transfer speed of the food.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing the entirety of the food vibrating feeder according to the present invention, and FIG. 2 is a side view showing a part of FIG. 1 in section. 1 and 2, the vibrating feeder according to the present invention includes a fixed plate 10 for accommodating a relatively small solid food 1 at an upper portion thereof. The fixing plate 10 is composed of two flat plates 12a and 12b which are opened upward in a V-shape. These flat plates 12a and 12b are fixed to an upper part of a support rod 14 which is fixed vertically to the base 2. I have. Flat plate 1
The lower ends of 2a and 12b are spaced at a distance sufficiently larger than the maximum dimension of the food 1, and constitute a gap 13 for taking out the food. Inclination angle and gap 1 between two flat plates 12a, 12b
The gap size of 3 can be appropriately adjusted by well-known means, for example, an elongated hole and a bolt, according to the food 1 to be processed.

With the above-described configuration, the food 1 piled up on the upper portion of the fixed plate 10 falls downward by its own weight, and falls downward from the gap 13. When the food 1 at the position of the gap 13 at the lower end of the fixed plate 10 is not carried out and stays at that position, the food on the upper side does not move downward and remains in a piled state, Is held.

A vibration trough 20, which is elongated and has a V-shaped vertical cross section, is provided along the lower end of the fixed plate 10 below and outside the fixed plate 10. The vibrating trough 20 has a lateral dimension at least larger than the gap 13 at the lower end of the fixed plate 10 and is substantially horizontal along the longitudinal direction of the trough (feeding direction of the feeder) or slightly downward in the feeding direction. It is inclined. The upper surface of the vibration trough 20 is
The vibration trough 20 is adapted to move food in the vertical direction of the vibration trough 20 by vibration from a vibrator 30 attached below the vibration trough 20.

As is apparent from FIGS. 1 and 2, the vibrator 30 comprises a lower horizontal plate 32, an upper horizontal plate 34, and a plurality of leaf springs 36 connecting these to each other. The lower horizontal plate 32 is fixed to the base 2 via an elastic member 33 such as a spring, and does not transmit vibration to the base 2.
A support member 35 attached below the vibration trough 20 is fixed to the upper surface of the upper horizontal plate 34. The leaf spring 36 is inclined in a direction opposite to the supply direction of the food 1, and upper and lower ends are fixed to the upper horizontal plate 34 and the lower horizontal plate 32, respectively. Further, an electromagnet 38 is fixed to the lower horizontal plate 32 via a mounting bracket (not shown), the upper surface of which is positioned with a slight gap from the lower surface of the upper horizontal plate 34, and the upper horizontal plate 34 is pulled downward. Have been.

With the above configuration, when a half-wave rectified current flows through the electromagnet 38, the upper horizontal plate 34 is attracted downward and vibrates. Since the vibration of the upper horizontal plate 34 is obliquely attached to the plate spring 36, it lowers to the lower left when the electromagnet 38 is turned on in FIG. 1 and restores the biased leaf spring 36 when the electromagnet 38 is cut off. This is a vibration that moves upward and to the right due to force.
The food 1 above 0 moves in the supply direction of the trough 20 (to the right in the figure). The length of the leaf spring 36 of the vibrator 30 is set to a length sufficient to increase the amplitude, that is, a length such that the deflection of the leaf spring is sufficiently large. As a result, even if the food has strong adhesiveness, large vibrations occur in the trough,
For example, a vibration of about 3 mm can be given, so that the food on the trough can be moved forward.

Further, by giving the vibration by the electromagnet as described above, it is possible to immediately start and stop the vibration. That is, a predetermined amplitude can be given to the vibration trough simultaneously with the start of the vibration, and aftershocks generated when the vibration is stopped can be suppressed, so that a relatively small amount of solid food can be stably supplied in a fixed amount. it can. Based on this configuration, by intermittently vibrating the vibration trough,
The food 1 transferred to the outlet end of the vibrating trough 20 at a certain height is supplied to containers sequentially sent to the receiving end of the vibrating trough. The supply amount of the food 1 to the container can be arbitrarily controlled by specifying the vibration time. In addition, it is desirable to attach a sensor for detecting that a food container has arrived at the receiving port.

At the outlet end of the vibrating trough 20, food 1
A gate 22 that can be opened and closed is provided to prevent the movement of the gate. The shaft end of the gate 22 is fixed to the output shaft of the turning drive source 23, and the gate 22 is opened by turning the turning drive source 23 counterclockwise in FIG. By installing the gate 22, it is possible to prevent the food from dropping from the exit end of the vibration trough when the vibration trough is stopped.

Above the fixed plate 10, a second vibrating feeder 40 for controlling the food supply amount is further provided. Further, a sensor 42 for detecting the food 1 on the fixed plate is provided above the fixed plate 10. The second vibration feeder 40 has the same configuration as the above-described vibration feeder. The second vibration feeder 40 is started by detecting that the food 1 on the fixed plate 10 is small by the sensor 42, and supplies the food 1 to the fixed plate 10. I do.

According to the above configuration, since the fixed plate and the vibrating trough are separately provided, even if a vibration large enough to move the food is given to the vibrating trough, the vibration of the food held on the fixed plate is reduced. Is deterred. Thereby, the food between the lower end of the fixed plate and the upper surface of the vibration trough among the foods stored in the fixed plate is moved along the vibration trough directly under the influence of the vibration trough, and is moved above the lower end of the fixed plate. Certain foods are not affected by vibration and tend to stay in position on the fixed plate. Therefore, a boundary of a fixed height is formed near the lower end of the fixed plate, and only food having a fixed thickness on the vibration trough can be moved. Further, since only the vibration trough is vibrated, a large amplitude can be generated, and the present invention can be applied to a soft solid food which is easily sticked. This allows
A predetermined amount of food can be stably supplied by adjusting the layer thickness and the transfer speed of the food.

[0017]

Therefore, according to the present invention, it is possible to provide an apparatus which has a simple mechanism and is capable of stably supplying a relatively small amount of solid food in a fixed amount.
