Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an article feeding device for evenly distributing a group of articles, particularly foodstuffs, fed from an input path to a plurality of linear feeders.

[Conventional technology]

When selling products, especially food products, it is necessary to always pack them at a constant weight or the closest weight, for example, in bags.

For this reason, when a group of articles as products is sent from the delivery route, this group of articles is divided into multiple groups of articles as evenly as possible, and any group of articles is selected from among these multiple groups of articles. The practice is to combine them and distribute them to a constant weight or the closest weight. A general example of such an article supply device is shown in FIG.

As shown in FIG. 4, a plurality of linear feeders 12 are provided radially below a substantially conical distribution conical disk 11 provided below the tip 41a of the carry-in path 41. Intermediate hopper 42 provided sequentially below the tip 12a of 12,
An article receiver 45 is disposed below the weighing hopper 43 and memory hoppers 44a, 44b, a discharge hopper 48 is disposed below the article receiver 45, and a transport bucket conveyor 46 is disposed.

Of these, the distribution conical disk 11 and the linear feeder 12 are vibrated by a vibration mechanism.

In the article supply device configured in this way,
The group of goods supplied from the carry-in path 41 is delivered to the distribution cone 1
1 and deposited on a distribution conical disk 11 and a plurality of linear feeders 12 provided radially below the distribution conical disk 11.

When the distribution conical disk 11 and the linear feeder 12 are vibrated by the vibration mechanism, the accumulated products are moved downward from the tip 12a of the linear feeder 12 to the intermediate hopper 42 and the weighing machine hopper 4.
3. It is designed to fall into two memory hoppers 44a and 44b on the left and right.

Here, arbitrary groups of articles are selected and combined and dropped onto a conveyor bucket conveyor 46 at the same time by a discharge hopper 48. At this time, a plurality of memory hoppers 44a, 44a, two on the left and right
It is assumed that one of the left and right memory hoppers 44a and 44b of arbitrary memory hoppers 44a and 44b among the memory hoppers 4b becomes empty.

Then, the weighing hopper 43 above the empty memory hoppers 44a and 44b opens after a certain period of time upon detecting the emptying, and then the intermediate hopper 42 above the weighing hopper opens, and then the intermediate hopper 43 opens. The straight feeder 12 above the hopper vibrates and supplies the goods to the empty intermediate hopper 42. When the amount of goods accumulated on the straight feeder 12 decreases due to this operation, the distribution cone 11 vibrates and supplies the goods to the empty intermediate hopper 42. Articles are fed onto a linear feeder 12.

When this operation is repeated and the amount of articles accumulated on the supply conical disk 11 decreases, the detection device 47 detects this and supplies the articles from the conveyance path 41 onto the distribution conical disk 11.

[Problem that the invention attempts to solve]

By the way, in the above article supply apparatus, especially when the article is a food item, it is necessary to thoroughly wash and disinfect the distribution cone 11 and the direct feeder 12, which the food item comes into contact with, every day.

Since this disinfectant has sterilizing power, it is highly corrosive, and the remaining disinfectant will adhere to the mechanical parts of the conical disc vibration mechanism 1 and the feeder vibration mechanism 2 shown in Fig. 5, causing rust and shortening the life of the device. There is a problem.

Therefore, the above-mentioned whole-surface washing liquid is applied not only to the gap H between the distribution conical disk 11 and the linear feeder 12 in FIG. It is necessary to prevent it from entering the mechanism section 12.

Further, since the conical disc vibration mechanism and the feeder vibration mechanism generate a large amount of noise during operation, countermeasures are also required.

The present invention was developed in view of the above points, and it prevents the cleaning liquid from entering the above-mentioned vibration mechanisms during full-surface washing.
Moreover, it is an object of the present invention to provide an article feeding device that does not generate noise.

[Means for solving problems]

Therefore, in order to solve the above-mentioned problems, the article feeding device of the present invention has a shape in which the opening top surface of the large diameter portion 32 having a cylindrical shape is closed by the top plate 3a, and the large diameter portion 32 covers the entire outer periphery of the conical disc vibration mechanism 1 and the feeder vibration mechanism 2, and in the center of the lower side of the distribution conical disc 11 of the upper surface plate 3a, passes through the upper support part of the conical disc vibration mechanism 1. A mounting hole 31a for guiding the feeder vibration mechanism 2 is formed on the top plate 3a above the feeder vibration mechanism 2.
A support hole 33 that penetrates and guides the support rod 11a that supports the linear feeder 12 is formed, and the inner periphery of the mounting hole 31a and the support hole 33 has an upper edge 33,
Waterproof cover 3 formed with protruding portion 31b
and a closing member 50 that closes off the space between each of the support rods 11a and the support hole 33.

[Effect]

In the above article supply device, the article (food)
The distribution conical disk 11 and the linear feeder 12 that are in contact with
When the entire surface is washed with water, the washing liquid flows downward from the top plate 3a of the cover 3 through the outer wall of the large diameter portion 32, and does not enter the internal vibration mechanism. That is, the washing liquid flowing onto the top plate 3a is prevented from entering the cover 3 through the attachment hole 31a and the support hole 33 by the protruding edges 33a and 31b, even when the amount of washing liquid is large. Since the mounting hole 31a is covered by the large-diameter distribution cone 11 and the many support holes 33 are closed by the closing member 50, it is said that the washing liquid infiltrates into the interior through each hole. Never.

In addition, garbage such as product (food) scraps that fall downward from the outer periphery of the distribution conical disk 11 and the linear feeder 12 accumulates on the top plate 3a of the cover 3, and this garbage is also removed from the cover 3 along with the washing liquid during the above-mentioned washing. It will be washed away from the exterior wall.

Furthermore, the cover 3 blocks vibration noise generated from the conical disc vibration mechanism 1 and the feeder vibration mechanism 2.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a diagram showing the article feeding device of the present invention with a cover attached. In FIG. 1, a distribution conical disk 11 is mounted and supported above the conical disk vibration mechanism 1, and below this distribution conical disk 11, a plurality of linear feeders 12 are mounted and supported above the feeder vibration mechanism 2. They are arranged radially.

The linear feeder 12 is positioned along the outer periphery of the distribution conical disk 11 so as not to come into contact with the distribution conical disk 11.

On the other hand, the cover 3 is attached below the distribution conical disk 11, and has a circular hat-shaped cross section that spreads out below the plurality of linear feeders 12.

This cover 3 forms a boundary surface in which the distribution conical disk 11 and the plurality of linear feeders 12 are located at the top, and the conical disk vibration mechanism 1 and the linear feeder vibration mechanism 2 are located at the bottom. .

FIG. 2 is a perspective view showing the entire cover 3. As shown in FIG.

As shown in FIG. 2, the cover 3 has a hat shape with a circular cross section as a whole, that is, the upper surface of the cylindrical large diameter portion 32 is closed by the upper surface plate 3a, and A mounting hole 31a is formed in the center of the face plate 3a, and the upper face plate 3a around the mounting hole 31a is projected upward one step to form a small diameter portion 31.

Further, in the upper surface plate 3a between the small diameter part 31 and the large diameter part 32, there are support holes 33 arranged radially from the center of the cover 3.
It is shaped so that the area around it is raised.

That is, an edge 33a is formed on the inner periphery of the support hole 33 to protrude upward, and an edge 31b is formed on the inner periphery of the attachment hole 31a to protrude upward.

As shown in FIG. 1, the cover 3 formed in this manner is configured such that the distribution conical disc 11, which is mounted and supported from the upper part of the conical disc vibration mechanism 1, protrudes from the mounting hole 31a formed in the small diameter portion 31. Also, the support rod 1 of the feeder vibrating mechanism 11 is inserted through the support hole 33 formed in the upper surface plate 3a between the small diameter part 31 and the large diameter part 32.
1a is attached so as to protrude. The space between each support rod 11a and the support hole 33 is closed by a closing member 50.

Therefore, the cap-shaped cover 3 is a conical vibration mechanism 1
and the feeder vibration mechanism 2 and its hat-shaped cover 3
It is designed to be stored inside.

Next, the conical vibration mechanism will be explained based on FIGS. 3A and 3B.

In the present invention, the conical vibration mechanism uses an air vibrator 20 that vibrates up and down.

In FIGS. 3A and 3B, the piston 22 reciprocably provided in the cylinder barrel 21 has first and second air injection holes 23a and 23 that penetrate laterally.
Two pistons b are formed on the top and bottom, and the piston 2
In the longitudinal direction of 2, there is a first air outlet hole 24a communicating from the center of the upper first air injection hole 23a into the lower cylinder barrel 21 space SA, and a first air outlet hole 24a communicating from the center of the lower second air injection hole 23b to the upper side. cylinder barrel 21
A second air outlet hole 24b communicating with the space SB is penetrated therethrough.

The cylinder barrel 21 also has air exhaust holes 25a and 2 that communicate with the outside from the upper cylinder barrel 21 space SB and the lower cylinder barrel 21 space SA.
5b, and an inlet 27 for introducing air from the air supply device 26.

On the other hand, a coil spring 28 for starting is installed inside the upper cylinder barrel 21 space SB, and when air is not flowing in from the air inlet 27, the air inlet 27 is connected to the upper first air inlet. It is biased so as to communicate with the hole 23a.

In such a configuration, when air flows in from the air inlet 27, the air flows from the upper first air injection hole 23a through the first air outlet hole 24a into the lower cylinder barrel 21 space SA, and the lower air flows into the lower cylinder barrel 21 space SA. The piston 22 moves upward due to the pressure between the cylinder barrel 21 spaces SA.

With this movement, the air inlet 27 no longer communicates with the first air injection hole 23a, and the inside of the space SA of the lower cylinder barrel 21 comes to communicate with the outside via the air exhaust hole 25a formed in the cylinder barrel 21. , lower cylinder barrel 21 space SA
The space that has flowed in will be discharged to the outside.

As the movement further progresses according to the inertial force, the air inlet 27 comes to communicate with the second air inlet 23b, and the air flowing in from the air inlet 27 flows from the second air inlet 23b to the second air inlet 23b. Air flows into the space SB of the upper cylinder barrel 21 through the air outlet hole 24b.

As a result, the piston 22 moves downward, and along with this movement, the air inlet 27
The space SB of the upper cylinder barrel 21 no longer communicates with the second air inlet 23b, and the space SB of the upper cylinder barrel 21 communicates with the outside via the air discharge hole 25b formed in the cylinder barrel 21, and the upper cylinder barrel 2
The air that has flowed into one space SB will be exhausted to the outside.

In this process, the piston 22 reciprocates up and down, and the distribution conical disk 11 supported by the support springs 11a, 11a vibrates in the up and down direction. Note that the noise generated during vibration is muffled by a muffler 29 attached to the lower part of the air vibrator 20.

The vibration of the distribution cone by the air vibrator 20 has a large vibration width and a strong force, so it has the advantage that a sufficient effect can be obtained even when distributing a viscous article, for example.

In the example, the material of the conical disk is stainless steel,
The size is set to 350 mm in diameter and 20 degrees inclination angle, and the vertical amplitude of this conical disc is 0.5 to 2.0 mm, and the period is 3400 to 2.0 mm.
When vibrated at 5000 rpm, highly viscous foods such as natto and Wiener sausages, which previously could not be distributed evenly, can now be distributed extremely smoothly.

[Effect of idea]

As explained above, according to the article supply device according to the present invention, the upper surface and the outer periphery of the conical disk vibration mechanism 1 and the feeder vibration mechanism 2, which are located below the distribution conical disk 11 and the linear feeder 12, vibrate them. The entire structure is covered by a cover 3 formed by closing the opening upper surface of a large diameter portion 32 having a cylindrical shape with an upper surface plate 3a. When washing the entire straight feeder 12 with water, the washing liquid flows downward from the top plate 3a of the coverna 3 through the outer wall of the large diameter portion 32,
This has the excellent effect of extending the service life of the vibrating mechanism without penetrating the vibrating mechanism inside and causing rust or deterioration of the vibrating mechanism.

Further, the top plate 3a of the cover 3 is provided with a mounting hole 31a for guiding the upper part of the conical disc vibration mechanism 1 and a large number of support holes 33 for guiding the support rod 11a that supports the linear feeder 12. The inner periphery of the mounting hole 31a and the support hole 33 has an edge 33a,
31b is provided in a protruding manner, the infiltration of the washing liquid from this mounting hole and the support hole is also prevented, and the mounting hole 31a is located on the lower surface of the large-diameter distribution conical disc 11 and is covered, and each support hole 33 is closed by the closing member 50, there is no possibility that the washing liquid will enter the inside through these holes and deteriorate the vibration mechanism.

Further, according to the present invention, garbage such as article (food) scraps falling downward from the outer periphery of the distribution conical disk 11 and the linear feeder 12 is removed from the upper surface plate 3a of the cover 3.
Since it does not accumulate on the top and scatter on the internal vibrating mechanism or on the floor as in the conventional case, during the above-mentioned washing, this dirt is washed away from the outer wall of the cover 3 along with the washing liquid at once, and the fallen dirt is removed. It is easy to work with and has excellent hygiene.

Furthermore, according to the present invention, since the entire vibration mechanism is covered by the cover 3, generation of noise can also be prevented.
