[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supplying solids, and more particularly, to an apparatus for quantitatively supplying solids such as food to a predetermined container.

[0002]

2. Description of the Related Art As shown in FIG. 3, conventionally, a stopper plate 51 is provided on a top of a trough 50 so as to be pivotable so as to be supplied quantitatively while separating an object. Is swung by an air cylinder 52 or the like, so that the trough 5
0 was opened and closed to supply a predetermined amount of raw material to the container below the trough. However, in such an apparatus, particularly in an apparatus in which the head between the trough and the container below the trough is large, for example, when processing a raw material that is easy to jump, a part of the raw material jumps from the trough to the lower container due to inertia, or Hit the stopper in the middle of opening and scattered in various directions, and often did not enter the predetermined container. Also, when processing raw materials that are easily attached and entangled, large vibrations are given to the trough to facilitate transportation, and raw materials that jump greatly at the end of the trough often do not enter a predetermined container. Was. In addition, the raw material adhering to the stopper plate is often shaken off by the swing of the stopper plate and scattered downward. Therefore, there has been a problem that a predetermined amount cannot be supplied to the container, and that the raw materials not stored in the container stain the periphery of the apparatus.

[0003] Furthermore, when a storage section of a measuring device for measuring the weight of food, ie, a weighing hopper, is juxtaposed downward, food that is easily entangled enters another juxtaposed hopper, and the weighing accuracy deteriorates. there were.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and is capable of supplying solids such as foodstuffs to a predetermined container quantitatively and without polluting the periphery of the apparatus. It is an object of the present invention to provide a supply device for goods.

[0005]

According to the present invention, there is provided a feeder for supplying solid matter from a trough having a bottom portion and both side surfaces to a container located at the lower end of the trough. A stopper having a closed position for closing the tip of the trough and an open position for opening the tip of the trough, the stopper being parallelly moved at a fixed angle in opposition to the supply direction of the solid matter in the trough; Is located below an extension of the bottom of the trough when the stopper is in the open position.

[0006] The stopper is a flat surface, and a surface of the flat surface facing the trough is inclined lower than a vertical surface.
Is preferred. Further, it is preferable that both side surfaces of the trough extend to a position forward of an opening position of the stopper.

[0007]

According to the solid supply device described above, the solid supplied to the trough is conveyed to the tip of the trough. However, when the stopper is in the closed position and the tip of the trough is closed, the solid is moved downward from the trough. Not supplied. When the stopper moves in parallel and opens the front end of the trough, the solids sent by the trough fall from the front end of the trough and enter a container located below the front end of the trough. When the stopper is in the open position, the lower end portion of the stopper is located below the extension of the bottom of the trough, so that solids that have jumped over the container always hit the stopper and are stored in the container and do not jump out. . Also, since the surface of the solid that has hit the stopper, which faces the trough of the stopper, is inclined below the vertical surface, the direction in which the solid rebounds even during the opening and closing of the stopper is constant. It does not come off from the container. Further, since both side surfaces of the trough extend beyond the open position of the stopper, they do not enter other containers arranged in parallel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. A solid supply vibrating trough 2 (hereinafter referred to as a vibration trough 2)
The vibration source 3 gives a straight-running vibration (arrow 4). At the tip of the vibrating trough 2, there is a stopper 8 operated by an air cylinder 12. The stopper 8 is opposed to the supply direction of the vibrating trough 2 by a piston rod 9 and a guide rod 10 as shown in FIG. Supported to move. Air cylinder 12
By the operation described above, the stopper 8 can move in parallel between a closed position where the tip of the vibration trough 2 is closed and an open position where the tip of the vibration trough 2 is opened. The inclination angle of the stopper 8 can be arbitrarily adjusted according to the properties of the target solid matter 5. The piston rod 9 and the guide rod 10 penetrate the guide plate 11, and the air cylinder 12 is fixed to the guide plate 11. Guide plate 1
1 is supported by another fixing portion (not shown).

In the closed position, the stopper 8 abuts against the tip of the vibrating trough 2, that is, the bottom surface 6 of the trough, and closes the trough outlet so that the solid matter 5 in the vibrating trough 2 does not come out of the stopper 8. It is in a state. In addition, the stopper 8 is in an open position where the tip of the vibration trough 2 is opened by retreating the piston rod 9 of the air cylinder, and the trough bottom 6 of the vibration trough 2 is opened to discharge the solid matter 5 to the lower part. That is, the stopper 8 forms a kind of gate. When the stopper 8 is in the open position, the lower end portion 8a of the stopper is located lower than the extension of the bottom of the trough. At the tip of the vibrating trough 2, both side surfaces 7 of the trough extend longer than the open position of the stopper 8, and the extension is located at an adjacent boundary portion of the lower measuring container 13. A weighing container 13 having a gate 14 which can be opened and closed is provided at the lower end of the vibrating trough 2. The weighing container 13 is supported by a weight measuring unit 15, and the weight measuring unit 15 is fixed to a main body base 16. A chute 17 for transferring the solids 5 to a subsequent stage (not shown) is provided at a lower portion of the measuring container so as not to be scattered at a time. As shown in the plan view of FIG. 2, the above-described series of devices are arranged in a plurality of rows adjacent to each other to constitute the entire solid material supply device.

The above-described solid material supply device operates as follows. Solid 5 supplied by solid supply chute 1
Is conveyed onto the vibration trough 2. The vibration trough 2 receives the vibration of the vibration source 3 and conveys the solid matter 5 to the trough tip. However, when the stopper 8 is closed, that is, when the trough bottom 6 is in contact, the vibration trough 2 does not vibrate and the solid matter 5 Do not transport. At the start of weighing, the weighing container 13 is empty, and a solid is charged into the weighing container by a signal from a controller (not shown). At this time, the stopper 8 is moved in parallel in accordance with the operation of the air cylinder 12, and the tip of the trough is opened. In parallel with this operation, the vibration trough 2 starts to be conveyed by the start of vibration of the vibration source 3, and the solids sent by the vibration trough 2 fall from the trough tip and enter the measuring container. Further, a part of the solid matter that has passed over the container hits the stopper and rebounds into the measuring container. Since the stopper is always slightly inclined downward with respect to the trough supply direction, the direction in which the solid rebounds is constant even during opening and closing of the stopper, and does not come off from the measuring container. Further, the side surface of the trough, that is, the leading end portion of the rising portion is longer than the moving range of the stopper and widened below, so that the trough does not enter other measuring containers arranged in parallel.

Although the present invention has been described with respect to a case in which weighing hoppers for measuring the weight of food are juxtaposed downward, the present invention is not limited to this.

[0012]

As described above, according to the configuration of the present invention, even when solid matter such as food supplied from the trough jumps over the container below the trough, the solid object such as food bounces back on the stopper and accurately comes to the predetermined container. Can contain solids. Therefore, solids such as food can be quantitatively supplied to a predetermined container. In addition, since scattering of solids around the apparatus is reduced, the apparatus is always cleaner than before, and the cleaning and cleaning operation can be simplified.
