This relates to a device that automatically divides and feeds almost fixed amounts of food in a certain state while being conveyed on the same belt conveyor.

Taking bagging of bean sprouts as an example, the work of dividing the bean sprouts into bags was mostly done by hand at a cottage factory.

In other words, the accumulated bean sprouts can be measured by eye or hand, etc.
It was divided and divided into sections and then fed to the bagging machine.

For this reason, this work requires particular experience, and even for those who are quite experienced, manual work is unstable and the weight of the packed items often varies.

Furthermore, agricultural products such as bean sprouts have moisture attached to them, making the labor extremely harsh especially in winter, which tends to increase labor costs.

The present invention can virtually quantitatively divide agricultural products, especially those with irregular shapes and instability such as bean sprouts, and has a simple structure, so it can be placed low and can be speeded up extremely easily. The purpose is to provide an automatic dividing feeding device that can do this.

Hereinafter, an embodiment in which the device according to the present invention is adopted as an automatic dividing and feeding device for bean sprouts will be described in detail based on the drawings attached to this specification.

In the following explanation, bean sprouts will be used as an example of the item to be supplied separately, but it goes without saying that the item is not limited to this.

Overall Structure The overall structure of the automatic bean sprout dividing and feeding device employing one embodiment of the device according to the present invention is as shown in Fig. 1, which includes a belt conveyor A on which bean sprouts are loaded and conveyed, and a belt conveyor A that is arranged across the top of the belt conveyor A. An upper scraping mechanism B is installed to smooth the top surface of the bean sprouts that are carried on the belt conveyor A, and the top scraping mechanism B smooths the top surface of the bean sprouts that are sent by the belt conveyor A in an approximately equal amount per unit length on the belt conveyor. Dividing mechanism C1 that divides into almost fixed amounts The upper scraping mechanism B
Return conveyor D returns the surplus bean sprouts scraped off by
The main part is a bean sprout accumulating table E for accumulating bean sprouts and supplying them to a belt conveyor A.

Next, these individual configurations will be explained in more detail.

Belt conveyor A In Figures 2 to 4, 1 indicates rubber, vinyl composite,
Alternatively, the bottom belt 1 may be made of metal or the like, and the bottom belt 1 is an endless belt that is passed between a roller 2 and a bottom belt drive pulley 3, as shown in FIG.

Reference numeral 4 denotes side belts made of a suitable material and disposed along both side edges of the bottom belt 1, and this side belt 4 is in the form of an endless belt that is passed between a roller 5 and a side belt drive pulley 6. doing.

The bottom belt 1 and the two side belts 4, 4 form a box-shaped belt conveyor A that conveys sprouts in the form of a continuous stack having a predetermined cross-sectional area.

Note that 7 is a guide plate disposed along the side belt 4, and 8 is a side frame surrounding the return side of the bottom belt 1.

In the present invention, this belt conveyor may have an appropriate configuration depending on the items to be conveyed.

Upper scraping mechanism B This mechanism B scrapes off the raised parts of the bean sprouts that are conveyed on the box-shaped belt conveyor A made up of the bottom belt 1 and side belts 4 mentioned above, and also scrapes off the hollow parts. It performs a replenishing function, and has an endless chain 12 that extends between a driving sprocket 10 and a driven sprocket 11.

Pin attachment plates 13 extending in a direction transverse to the endless chain 12 are attached at predetermined intervals, and pins 14 are fixed to the attachment plates 13 at intervals.

15 is a sprocket for the belt conveyor A, as shown in FIG. , a rack and pinion, or a bolt and nut, etc., and the amount of bean sprouts scraped off from the belt conveyor A is adjusted by adjusting this slide.

A drive wheel 16 is attached to the shaft of the drive sprocket 10 and is driven by an appropriate drive device.

The bean sprouts 17 scraped off by the pins 14 moving by this mechanism B are returned to the bean sprout accumulation table E by the return conveyor D described above.

Splitting mechanism C The dividing mechanism C will be explained using FIGS. 8 to 11.

In FIGS. 8 to 10, 20 is a slide rod pivotally mounted around a shaft 21, 22 extends parallel to the slide rod 20, and one end is connected to the corresponding end of the slide rod by a connecting member 23. Similar to the slide rod 20, the slide rail is pivotally mounted around a shaft 21 so as to be swingable.

Two sliders 24.25 are fitted into the slide rod 20 so as to be slidable along the slide rod 20, and both sliders 24.25 are attracted to each other by a spring 26.

A crank 27 is fixed to the shaft 21, and this crank is connected to the slider 24 by a connecting rod 28, so that rotation of the crank 27 gives reciprocating displacement to the slider 24.

29 is a drive wheel for rotating the crank 27 via the shaft 21.

The crank 27 and the connecting rod 28 constitute a reciprocating drive device for the slider.

A link 30 is fixed at one end to the slider 25, and one end of a link 31 is attached to the other end of the nonch 30.

The link 31 is pivotally connected by a pin 33 to a bracket 32 provided between both ends thereof and protruding from the slider 24.

Next, pin mounting brackets 36 and 37 are attached to sliders 24 and 25, respectively, in which pins 34 and 35 are arranged as dividing members in the direction across the bottom belt 1, and are attached so that the two pins are staggered. This metal fitting is 36.3
A pair of rolls 38 and 39 are respectively supported at the rear ends of the rollers 7, and the slide rail 22 is sandwiched between the roll pairs.

One end of a cam rod 40 is pivotally attached to the slide rail 22 and hangs down therefrom.

A cam roller 41 is pivotally connected to the lower end of the cam rod 40, and the lower end of the cam rod 40 is held in a horizontal position by a cam lever 42 which is pivotally connected to an appropriate fixed point by a support shaft 43.

The cam roller 41 is in contact with a rotary cam 45 fixed to a rotary drive shaft 44 .

This rotation of the cam 45 causes the cam roller 41. Slide rail 22 and slide rod 2 via cam rod 40
0 is swung up and down about the axis 21 as shown in the imaginary line in FIG.

These cam rods 40, cam rollers 41. A rocking mechanism is composed of the cull lever 42, the cam 45, and the like.

The cam 45 moves the slide rod to the solid line position shown in FIG. 9 when the slider 24, 25 is displaced on the slide rod in the direction of the shaft 21, and to the position shown in FIG. 9 when the slider is separated from the shaft 21. It is rotated in synchronization with the crank 27 to bring it to the virtual line position.

46 is a fixed stopper, and the lower end of the link 31 comes into contact with this stopper 46 when the slider is in the solid line position in FIG.

This stopper 46 and the aforementioned links 30, 31 . The bracket 32, the pin 33, and the spring 26 constitute a dividing drive device that provides a dividing operation to the slider dividing members.

Next, the operation of this dividing mechanism will be explained using FIGS. 11a, 1) and 11c.

In FIG. 11a, the cam rod 40 has been lowered into engagement with the recess of the cam 45, and the slide rail 22 and slide rod 20 are in a horizontal position, with the pin 34.35 serving as a dividing member of the slide 24.25. is close to the upper surface of the bottom belt 1.

In this state, the slides 24 and 25 are pushed by the connecting rod 28 as the crank 27 rotates and are moved on the slide rod 20 in a direction away from the shaft 21.

The moving speed of the slides 24.25 and therefore the pins 34.35 at this time is selected to be equal to the moving speed of the belt conveyor A.

When the sliders 24 and 25 are moved forward as one in this state, the lower end of the link 31, one end of which is pivotally connected to the slider 25 via the link 30, comes to a position where it abuts the stopper 46.

In this state, the slider 2 is
4 is further displaced forward, the lower end of the link 31 hits the stopper 46 and cannot move forward, so the link 31 is rotated clockwise around the pin 33.

As the link 31 rotates around the pin 33, the slider 25 stretches the spring 26, is separated from the slider 24, and is projected forward via the link 30.

This state is shown in FIG.

The thrusting operation of the slider 25 is performed by displacing both sliders 24, 25 at approximately the same speed as the belt conveyor A, so the moving speed of the slider 25 at this time is faster than the moving speed of the belt conveyor. has also been sped up.

Therefore, looking at the pins of both slides 24 and 25 that are stuck in the bean sprouts on the belt conveyor A, the pin 34 is moving at the same speed as the bean sprouts M on the belt conveyor, but the pin 35 is in front of it. Push the bean sprout Ml forward and divide it.

This state is shown by the broken line in FIG.

At this point, the cam 45 displaces the cam rod 40 upward and lifts the slide rod 20, so the link 3
1 comes out of contact with the stopper 46, the slider 25 is pulled back toward the slider 24 by the force of the spring 26, and the link 31 is rotated counterclockwise around the pin 33 and returned.

After one division is completed and the rod 20 is lowered, the next division operation can be repeated in the same manner.

Return conveyor D and bean sprout collection table E The return conveyor D may be an appropriate conveyor that returns the bean sprouts scraped off by the upper scraping mechanism B to the collection table. A size and shape that allows a predetermined amount of information to be accumulated may be adopted as appropriate.

Overall operation The bean sprouts to be packed in bags collected on the bean sprout accumulating table E are sent on the belt conveyor A, the upper surface of which is smoothed by the pin 14 of the upper scraping mechanism B, and excess bean sprouts are accumulated on the return conveyor D. It is returned to the table E and is conveyed in a predetermined amount per unit length of the belt conveyor A.

When the splitting mechanism C is inserted, the pins 34 and 35 are thrust into the bean sprouts on the belt conveyor A as the slide rod 20 is lowered, and the pins 34 and 35 are displaced together with the bean sprouts. The accompanying movement is suppressed by the pin 34, and the bean sprout Ml in the front is pushed out and divided by the pin 35.

After splitting, the pin 34.35 is lifted together with the slider 24.25 as the slide rod 20 rises, and the spring 2
6, they become one body and are pulled back on the slide rod 20 by the crank 27.

During this time, the bell 1 to conveyor A are moving continuously, and when the pins 34 and 35 are lowered again by the action of the cam 45, they are pierced by the bean sprouts on the bell) and conveyor, and the same dividing operation as described above is repeated. I'll give it back.

The divided bean sprouts Ml are appropriately automatically packaged in the next step.

Above, one embodiment of the device according to the present invention has been specifically described, but the upper scraping mechanism B and the return conveyor D may or may not be provided depending on the items to be divided, and if provided, the same applies as described above. It goes without saying that it may be of any suitable structure depending on the item.

In addition, in the one-divided drive device in the splitting mechanism C in the embodiment described above, the reciprocating motion by the crank 27 is transmitted to the sliders 24 and 25, but this is not the only option. It goes without saying that a device may be used, and the operation of pushing out the slider 25 relative to the slider 24 may be performed by using a fluid pressure cylinder, electromagnetism, or another link instead of the links 30, 31, stopper 46, and spring 26. It will be obvious to those skilled in the art that the configuration can be adopted as appropriate.

In either case, any type of splitting drive device that holds down the following items on the belt conveyor with one slider at a predetermined position where the slider is brought close to the belt conveyor and divides the items by protruding a certain amount from the front is sufficient. .

Furthermore, it is of course possible to use another mechanism for the swinging mechanism of the slide rod instead of the combination of a cam and a cam rod.

As described above, according to the present invention, items such as sprouts are continuously conveyed by a belt conveyor, and the divided members of the slider, which are displaced at approximately the same speed as the conveyance speed, are brought close to the belt conveyor and together By adopting a simple configuration in which one slider is not moved but is protruded by a predetermined amount at a predetermined position, the predetermined amount can be automatically divided.

This divided weight can be easily changed by adjusting the moving speed of the belt conveyor, replacing sprockets in the drive system, or adjusting the height of a scraping mechanism when used together.

Furthermore, according to the device of the present invention, the dividing member of one slider prevents subsequent items from being squeezed and ejected on the belt conveyor, and the dividing member of the other slider pushes out a predetermined amount. Therefore, even irregular and intertwined items such as bean sprouts can be accurately divided into approximately equal amounts.
