Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for measuring chips of a highly viscous substance such as cheese cut into strips in a fixed shape and supplying a predetermined amount of the chip to the next process. The present invention relates to a conveyance device.

In general, chips made by cutting highly viscous substances such as cheese into regular pieces are viscous, so they may stick to each other during transportation and form blocks, or if too much external force is applied to them. There are problems such as damage to the fixed shape, and as with other highly fluid substances such as powders or liquids, proportional control or ratio control, and if the specific gravity is uniform, volumetric filling is possible. Compared to things that can be measured mechanically, there was no device that could measure and supply the material.

The present inventors have devised an invention in view of the above-mentioned problems, in which chips of cheese cut into regular-sized strips are kept in a high-viscosity substance, etc., and packaged in bags while maintaining the same state. was invented to be used as a conveying device for a device that can mechanically place and measure topping materials for pizza pies and the like.

That is, a plurality of belt conveyors are arranged in stages, and a bar-shaped rotor is rotatably provided at the discharge end of a first conveyor that directly receives chips of high-viscosity substances such as cheese from a feeder. are arranged at regular intervals on a concentric circle of a rotation axis that intersects the traveling direction of the conveyor, and at least one of the other conveyors.
In one method, a plate-shaped rotor is rotatably provided at a fixed distance above the conveyor, and a plurality of plates are protruded radially from a rotation axis that intersects the direction of travel of the conveyor at fixed intervals. The conveyor is constructed of a conveyor, and each rotor is configured to rotate in a direction opposite to the direction in which the conveyor travels.

According to the conveying device of the present invention, the chips are conveyed in a uniformly dispersed state from the feeder section to the weighing section without sticking to each other or deforming, and the subsequent weighing can be performed mechanically without uneven conveyance. It has the characteristic of being able to

The embodiments shown in the drawings will be described below.

The examples will be described with respect to those used in the cheese topping step in the production of pizza pies, but it is of course applicable to other highly viscous substances.

1 is a first belt conveyor that directly receives chips from the feeder.

Although the feeder is not shown, the cheese block is sliced into strips with a size of about 0.2 to 5 g using a slicer, e.g. 2 mm x 7 mm x 15 mm, or 0.2 g or 2 mm x 7
Chips cut into 0.4 g pieces (mm x 30 mm) are first transferred from the chip storage conveyor to a mobile transfer hopper, and from this mobile transfer hopper to a fixed transfer hopper, the chips are received by the first belt conveyor. ing.

The fixed transfer hopper is opened after checking the conveyance end of the first belt conveyor.

Therefore, a constant amount is supplied to the first belt conveyor.

Since there is a flow control rotor having the same shape as the bar-shaped rotor described later on the outlet side of the chip storage conveyor, the cheese chips are supplied to the first belt conveyor without damaging their original shape. Reference numerals 2, 3, and 4 are other belt conveyors provided in stages from the first belt conveyor 1, and the speeds are sequentially increased from low speed to high speed.

For example, if the first belt conveyor is 0.2 to 0.8 m/min, 2.7 m/min, 9 m/min, and 30 m/min, respectively.
It's a minute.

Reference numeral 5 denotes a bar rotor that is rotatably provided at the discharge end of the first belt conveyor 1, and a bar 7 parallel to the rotation axis 6 that intersects the direction of movement of the first conveyor 1 is arranged on a concentric circle of the rotation axis 6. It consists of elements arranged at regular intervals.

In the illustrated example, a rotating shaft 6 is rotatably mounted on a bearing fitting 10 supported by a pair of right and left supporting fittings 9 on a frame 8, and a bar 7 is stretched between side plates 12.

11 is a pulley for driving the rotating shaft 6. The rotor rotates in the direction of movement of the belt conveyor as shown by the arrow in the figure.

Reference numeral 13 denotes the left and right guide plates of the first belt conveyor 1, and the portions corresponding to the bar rotor portions are constructed to prevent chips from spilling as shown in the figure.

Next, 14 is a plate-shaped rotor that is rotatably mounted on the third belt conveyor 3 at a certain distance.

This plate-shaped rotor 14 has a plurality of plates 16 protruding from a rotating shaft 15 that intersects the direction of movement of the third belt conveyor at regular intervals and radially at an angle of, for example, 30 degrees with respect to the vertical direction. It is configured.

In the illustrated example, a rotating shaft 15 is mounted on a bearing fitting 19 supported by a pair of right and left supporting fittings 18 of a frame 17.
The rotating shaft 15 has a two-stage pulley 20 and a chain wheel 22 driven by a motor (not shown) via a chain 21 shown in FIG. 4.

The plate-shaped rotor rotates in a direction opposite to the direction in which the belt travels, as shown by the arrow, in the same way as the bar-shaped rotor.

Note that the bar-shaped rotor 5 described above is driven via a two-stage pulley 20.

Next, a plate-shaped rotor 23 similar to the plate-shaped rotor 14 is driven from the two-stage pulley 20 on the fourth belt conveyor 4, but the distance from each conveyor is that the plate-shaped rotor 1
The plate-shaped rotor 23 is smaller than the rotor 4.

Note that 24 and 25 are guide plates on both sides of the second belt conveyor 2 and the third belt conveyor 3, and the distance between the left and right guide plates becomes gradually narrower. However, a portion of the rotor 14 of the third belt conveyor 3 protrudes upward in a ladder shape 25a.

The fourth belt conveyor 4 also has a similar guide plate.

FIG. 5 is a diagram showing the operating principle of the conveying device of the present invention, and 26 is a fixed transfer hopper of the feeder, which is provided below the movable transfer hopper (not shown) and is designed to supply a fixed amount of cheese chips. ing.

Further, 27 indicates a remaining amount detection area on the first belt conveyor, and a photo switch 28 detects the remaining amount on the first belt conveyor.

29 is a preliminary weighing hopper of the weighing section;
is the main weighing hopper of the weighing section.

Now, when a predetermined amount of cheese chips are supplied from the feeder to the first belt conveyor 1, the chips are loosened and dispersed by the bar-shaped rotor 5 at the discharge end and transferred to the second belt conveyor 2.

Then, when moving from the second belt conveyor 2 to the third belt conveyor 3, large particles are further dispersed by the plate-shaped rotor 14, and the thickness is equalized to an average layer thickness by the distance h from the belt conveyor, and then transferred to the next fourth belt conveyor 4. be transferred.

Here, the layer is further leveled to an average thin layer thickness that is at least the width of the chips depending on the distance _h1 from the belt conveyor, and is supplied to the measuring sections 29 and 30, where a predetermined amount that can be topped on the crust is measured and added to the crust. Topped.

Therefore, the speed of the belt conveyor increases from the first belt conveyor to the fourth belt conveyor, and the layer thickness of the chips to be conveyed gradually becomes thinner as the distance between the plate-shaped rotor and the belt conveyor is reduced. Become. However, the speed of the belt, the distance of the plate-shaped rotor to the belt conveyor, and the interval between the guide plates on the belt conveyor are set in advance so that the conveyance amount of each belt conveyor is constant.

Specifically, the speed of the first belt conveyor 1 is set to match the amount of measurement per unit time and to allow sufficient replenishment of chips.

In the second belt conveyor 2, there is no plate-shaped rotor 14 and the layer thickness is large, so the flow control effect is small, but the material is dispersed and transported in a fluffy state by the rotor of the first belt conveyor. Therefore, care must be taken as sudden acceleration will increase conveyance unevenness.

The fourth belt conveyor 4 is set at a speed that allows individual chips to be conveyed in a separated state in order to improve measurement accuracy.

Further, the rotor 5 of the first belt conveyor 1 is
The chips conveyed by the belt conveyor 1 are rotated so as to be dispersed and actively sent.

Furthermore, the rotor 14 of the third belt conveyor 3
The unevenness of the conveyance is eliminated so that the medium blocks are transferred flatly, and the middle blocks that have passed through the gap between the rotor 5 of the first belt conveyor 1 and the conveyor are dispersed, and the rotor of the fourth belt conveyor 4 is It is preferable to rotate it in the same manner as the rotor of the belt conveyor 3, so as to disperse the small blocks that have passed through the gap between the third belt conveyor 3 and its rotor.

Level difference H at the connection between other conveyors
It is necessary to keep the chips small so that the chips do not concentrate when the conveyance is stopped.

In general, it is possible for non-viscous materials to shift from a thick layer to a thin layer by accelerating only the belt conveyor, but for viscous materials such as cheese chips, they do not disperse even if they are accelerated and are conveyed almost as they are. As a result, the chips form blocks, and each block is conveyed in an independent and dispersed manner, which increases the unevenness of conveyance as the chips accelerate.

However, since there is a bar-shaped rotor and a plate-shaped rotor as in the present invention, the above-mentioned uneven conveyance does not occur.

Therefore, it can be called a type of flow control.

To explain these functions in more detail, the bar-shaped rotor 5
This is effective when the layer thickness to be conveyed is large, and is particularly effective in dispersing non-solid cheese blocks, preventing free flow of cheese chips from the first belt conveyor, and actively increasing the amount of feed from the feeder.

If the bar-shaped rotor 5 of the present invention is not provided at the discharge end of the belt conveyor, it will break at the discharge end and form a large block P, as shown in FIG.

However, when the bar-shaped rotor 5 of the present invention is located at the discharge end of the belt conveyor, the rotation of the rotor creates a wall D as shown by diagonal lines as shown in FIG.
is formed, but the wall between bar A and bar B will be broken up by bar A.

Portion C is not affected by the bar and gradually flows out as the belt conveyor advances, but it is a small portion and is prevented from freely flowing out by the rotor.

Usually, the diameter of the bar is 5 to 6φ, and the diameter of the rotor is about 1.5d, assuming that the thickness of the chip layer is d. The gap between each bar changes depending on the conveyor speed, the size of the conveyed object, and the rotor rotation speed. For example, a tip for a pizza pie may be about 40 mm.

In any case, the bar-shaped rotor 5 has a large dispersion effect when used for a thick chip layer, and if the plate-shaped rotor 14 is used for such a thick chip layer, the plates will scrape up the chips, resulting in block-like chips. The plate-shaped rotor 14 is not used for the first belt conveyor 1 since the belt conveyor 1 is discharged to the next conveyor.

Since the first belt conveyor 1 can transport the chips in a thick layer, the chips can be supplied with a rough degree of dispersion. Even if the container is transported in a rough state with an uneven surface, the peaks are lifted up with a bar and pushed toward the valleys to smooth the surface, making it possible to correct uneven replenishment.

Next, plate rotors are effective in correcting conveyance unevenness at small flow rates.

In other words, it is rotated so that the scraped up material, which is used for products with a low chip layer thickness, slides off the plate.

And the damage to the chip caused by modification is far less than you might imagine.

This is thought to be because when the chips are randomly layered, they themselves have the effect of a cushion material, and the chips that are in a delicate relationship during correction can be moved by the cushion effect.

In general, highly viscous substances such as cheese tend to form blocks, so it is not possible to provide an average dispersed state through input. However, in the present invention, since the first belt conveyor has a bar-shaped rotor, even if the layer thickness is high, it is possible to feed the chips roughly, and from the final belt conveyor the chips are evenly distributed by the plate-shaped rotor. It has the feature of being able to measure accurately because it comes out.

If a block of material reaches the weighing section, accurate weighing will not be possible.

In any case, the present invention has a bar-shaped rotor rotatably disposed at the discharge end of the first conveyor that directly receives chips of highly viscous substances such as cheese from the feeder, which is different from other conveyors arranged in stages. By installing a rotatable plate-shaped rotor on both chips, even if the chips are viscous, they can be transported in a uniformly dispersed state while maintaining their original shape, and no large lumps will form, making it easier to weigh them later. It has the characteristic that it can be done mechanically.
