Description

  The present invention relates to a wire-type cutting device for cutting relatively soft items such as confectionery dough.

  In order to cut soft things, for example, clay-like things such as confectionery dough, a wire is often used. This is because if a cutting instrument such as a kitchen knife is used, the cutting area increases and the object to be cut is crushed. There exists a thing of the following patent document 1 as a cutting device using a wire, and this is a thing of the structure which fixes the wire to the opposite location of the outer periphery of the drum which rotates, and cuts the cut object on the conveyor inserted in the drum. It is.

According to this, since the object to be cut is pushed by the wire, there is a possibility that the shape of the object to be cut is broken by the pressing force, and the cut end may not be clean. In addition, since the object to be cut is always cut at the same portion of the wire, the wire may be worn quickly.

  According to the present invention, an object to be cut is cut with a wire, the shape is not destroyed, a clean cut end is ensured, and the life of the wire can be extended.

Under the above problems, the present invention provides a hollow drum that rotates in a fixed direction within a vertical plane, the other end pivotally attached to the outer periphery of the drum, and one end on the opposite drum side. A wire-type cutting device comprising a wire to be energized and first and second conveyors on the upper side in the transfer direction for transferring the object to be cut by passing through the drum. to rotate the drum in a direction which acts from above the wire against which the other that allowed interrupting the first and second conveyor by the action surface of the wire, and the second conveyor a plurality of round belts juxtaposed at a predetermined interval The wire-type cutting device is provided in which a brush roller is provided below the round belt that passes between the round belts and acts on the lower surface of the workpiece to be forcibly driven .

  According to the above means, since the object to be cut is so-called torn by the wire, the cutting property is improved and it can be cut with a light force. Therefore, the shape does not easily collapse and the cut is beautiful. Further, since the wire acts on the cutting in a long range exceeding the dimension of the workpiece, wear or the like hardly occurs.

The best mode for carrying out the present invention will be described below with reference to the drawings. 1 is a longitudinal sectional view of an essential part of a cutting device according to the present invention, FIG. 2 is an enlarged sectional view of a part A in FIG. 1, and FIG. 3 is a front view of the cutting device. in the drum 1 rotating in a certain direction, one end of which is fixed by being biased tension coil scan purine grayed 2 extendable, a wire 3 and the other end is fixed to the outer periphery of the drum 1, provided in the drum 1 , And a conveyor 5 that transfers the workpiece 4 through the drum 1.

  The drum 1 has a hollow ring shape, and is rotatably supported in a vertical plane by a bearing 7 or the like with respect to an arcuate fixing member 6. In this example, the drum 1 is driven by attaching a ring-shaped pulley 8 having the same diameter as that of the drum 1 to the back surface of the drum 1 and a geared motor 9 above the fixed member 6 and its output pulley 9a. A timing belt 10 is stretched between the pulley 8 and the pulley 8. The timing belt is used to suppress slippage, and may be a flat belt. In addition, a V belt, a chain, or a sprocket may be used. Further, driving may be performed by a gear and a pinion gear.

One end of the wire 3 is fixed to the fixing member 6 or the like and connected to the extendable coil spring 2, and the other end is pivotally attached to the outer periphery of the drum 1. In this example, an idle roller 11 is interposed in the vicinity of the drum 1 above the coil spring 2, and the wire 3 extends straight up to the idle pulley 11 and then changes direction to reach the drum 1. Furthermore, a tension pulley 12 that secures the tension of the wire 3 is also provided. For the pivotal connection between the wire 3 and the drum 1, a cam roller 13 is embedded in the surface of the drum 1, and the wire 3 is connected thereto.

  As a result, regardless of the rotational phase of the drum 1, the cam roller 13 always faces the idle pulley 11 and is kept in a constant tension state by the coil spring 2. One end of the wire 3 may be free and a weight may be suspended instead of the coil spring 2 (not shown). As described above, when the drum 1 is rotated, the pivot point of the wire 3 is also rotated together with the drum 1. At this time, the wire 3 is always kept in tension by the action of the spring 2.

  The conveyor 5 is generally a belt conveyor, and is installed in a horizontal state through the drum 1. The height of the conveyor 5 and the drum 1 is not particularly limited, but is usually set so that the center of the conveyor 5 matches the center of the drum 1. Accordingly, when the drum 1 is rotated, if the workpiece 4 is placed on the conveyor 5, the workpiece 4 is cut at the working surface of the wire 3. In this respect, the rotation direction of the drum 1 is set in a direction in which the wire 3 acts on the workpiece 4 from above (counterclockwise direction in FIG. 3).

  By the way, in order to perform the above-mentioned cutting, the conveyor 5 must be interrupted at the working surface of the wire 3. Therefore, in this example, the conveyor 5 is composed of a first conveyor 5a that ends immediately before the working surface of the wire 3, and a second conveyor 5b that starts immediately after the working surface, ensuring rotation of the wire 3 and cutting. The cut object 4 can be subsequently transferred from the first conveyor 5a to the second conveyor 5b.

  The second conveyor 5b of this example is configured by a plurality of round belts 14 arranged in parallel at a predetermined interval. That is, the round belt 14 is stretched in an inverted triangle shape in a side view and is driven by a geared motor 15 provided below. And in this example, the brush roller 17 similarly driven by the geared motor 16 is provided below the horizontal part of the upper surface. This is because the lower surface of the object 4 to be cut and transferred on top is powdered or the like, so that it is cleaned. In order to perform this smoothly, the brush roller 17 A part of the surface is in a relationship of coming into contact with the lower surface of the workpiece 4 through the interval of the round belt 14.

  Further, a carry-out conveyor 18 is also provided on the downstream side of the second conveyor 5b, and the workpiece 4 cut and cleaned by the brush roller 17 is placed on the carry-out conveyor 18 and transferred to a predetermined location. In this case, the speed of the second conveyor 5b is slightly higher than the speed of the first conveyor 5a. This is to prevent the cut workpieces 4 from sticking to each other.

  In addition, in this example, the wire 3 that has acted on the cutting can be cleaned. This is because chips or the like are attached to the wire 3 and are removed. Specifically, the brush wheel 19 that is in sliding contact with the idle roller 11 is fastened to the fixing member 6 with a bracket 20 or the like, and the wire is pinched by the idle roller 11 and the brush wheel 19. At this time, a water tank 21 is provided on the upper portion of the bracket 20 or the like, and water is dropped from the water tank 21 onto the brush foil 19 in a drip manner through the water conduit 22.

  The position where the brush foil 19 is provided needs to be within the range of the wire 3 that has acted on the cutting. For this purpose, when the drum 1 rotates and the cam roller 13 approaches the idle roller 11, The condition is that the length of the idle roller 11 is shorter than the length of the cam roller 13 and the workpiece 4 when the wire 3 acts on the workpiece 4. In this respect, the idle roller 11 is preferably provided as close to the drum 1 as possible.

  Next, the cutting and transfer of the workpiece 4 by the above cutting apparatus will be described. The workpiece 4 is in a state before being cut, that is, a continuous cross-section of a circle, an ellipse, or a polygon is placed on the first conveyor 5a and transferred to the drum 1 side. When a specific part of the workpiece 4 comes to the working surface of the wire 3, it is cut by the rotation of the wire 3 by the drum 1. At this time, the wire 3 is moved downward along with the rotation of the drum 1 and is pulled out from the idle pulley 11, and the workpiece 4 is cut, that is, pulled by pressing and pulling with the wire 3.

  Therefore, it can be cut with a light force and the cut end is also beautiful. At the same time, since the wire 3 acts on the workpiece 4 with a certain length at the time of cutting, wear is also reduced. Furthermore, since the wire 3 that has acted on the cutting is cleaned by the brush foil 19 each time, the chips and the like are removed, and the cutting performance is not deteriorated and is hygienic.

  By the way, at the time of this cutting, although the to-be-cut object 4 may be moved continuously (the 1st conveyor 5a moves continuously), if it says strictly, it will be cut | disconnected diagonally. In order to prevent this, while the wire 3 passes, the movement of the first conveyor 5a may be stopped (intermittent movement is performed). When the above cutting is completed, the wire 3 returns to the original position and cuts the workpiece 4 transferred during that time again. In this way, the workpiece 4 is continuously cut at a certain length.

It is a longitudinal cross-sectional view of the principal part of the cutting device which concerns on this invention. It is a principal part enlarged view of the A section of FIG. It is a front view of the principal part of the cutting device concerning the present invention.
