In the figure, 77 is a tension adjustment mechanism that changes the position of the driven shaft 13 to appropriately adjust the tension of the conveyor belt 18 of the conveyor 2, and 78 is a mechanism that prevents the conveyor belt 45 of the presser conveyor 3 from meandering. It is a spittle for the purpose.

Next, the operation of the above cutting device will be explained.

Prior to cutting the object to be cut, first, the height of the presser conveyor 3 is adjusted to an appropriate height according to the type of the object to be cut A by the height adjustment mechanism 47. That is, when the handle 50 of the height adjustment mechanism 47 is turned, the torque is transmitted to the screw member 54 in the order of the handle 50 → shaft 52 → bevel gears 51, 55 → screw member 54, and the screw member 54 rotates. As a result, the moving boss 56 moves in the axial direction of the screw member 54, and the connecting member 48 pushes and pulls a predetermined arm 28. and,
Each arm 27, 28 is raised and lowered, and the presser conveyor 3 is moved up and down while maintaining a horizontal state parallel to the conveyor 2,
The height is adjusted.

Next, the variable speed motor 22 is started to operate the transport conveyor 2 and the presser conveyor 3, and a switch (not shown) is turned on to cause each cutting edge 59 of each vibrating cutter 4 to vibrate slightly at high speed in the direction of arrow E, and to shake. Motor 74 of moving device 5
is activated to make each vibrating cutter 4 swing in the same direction. That is, when the variable speed motor 22 is started, its rotational force is transferred from the drive pulley 23 to the belt 24 to the pulley 19.
→The drive shaft 12 is transmitted to the drive shaft 12 in this order to operate the conveyor 2, and the rotational force of the drive shaft 120 is

Timing gear 35 → timing gear 46 → drive shaft 41
This is transmitted to the drive shaft 41 in this order, and the presser conveyor 3 is operated at the same speed as the transport conveyor 2. On the other hand, the rocking device 5
When the motor 74 rotates, the drive pulley 75 → transmission belt 76 → transmission pulley 70 → rotating shaft 71 → cam member 6
The rotational force is transmitted to the cam member 69 in the order of 9, and the connecting rod 7
The base end of the connecting rod 73 rotates around the axis of the rotating shaft 71, and the connecting rod 73 moves up and down. The swing member 65 is moved up and down by the connecting rod 73, and each vibrating cutter 4 is swinged in the middle E direction at a predetermined speed.

In this state, the workpiece A is fed from the starting end side of the conveyor 2. Then, the workpiece A is transported by the transport conveyor 2 in the direction of arrow B, but when it reaches the starting end of the presser conveyor 3, it is pressed from above by the presser conveyor 3VC and its posture is maintained. Taima vibration cutter 4
It can be transported to

Each cutting edge 5 of each photographic cutter 4 vibrates and swings.
It is cut and divided into predetermined shapes by 9 and transported as it is to the terminal end of the transport conveyor 2.

In this way, in the cutting device having the above configuration, the cutting edge 59
The object to be cut is cut by using a vibrating cutter 4 that is vibrated finely at high speed by ultrasonic waves or electromagnetic force, and by swinging the vibrating cutter 4 at a predetermined speed in the photographing direction E by a swinging device 5. As a result, cutting into the object to be cut is performed extremely smoothly and quickly, with almost no cutting chips being generated, and the durability of the cutting edge 59 is improved and the cutting edge 6
8. The frequency of replacement will be significantly reduced.

In addition, since the object to be cut is held down from above by the presser conveyor 3, the object to be cut will not shift or float during cutting, and therefore the object to be cut can be placed extremely accurately. Can be cut into desired shape.

Furthermore, the height of the presser conveyor 3 is adjusted by the adjustment mechanism 471C.
Therefore, since it can be adjusted freely, it can be used for cutting multiple types of objects with different heights.

Furthermore, since the main parts of the presser conveyor 3 can be freely removed by removing the inner frame 46 from the outer frame 32, cleaning of the conveyor belt 45, etc. of the presser conveyor 3 is extremely easy. It's easy to do.

Incidentally, the objects to be cut are mainly breads and processed meat products, but specific examples include bread, sandwiches, castella cakes, snack products, torte, salami sausage, bacon, ham, cheese, and the like.

Further, in the embodiments described above, the conveyor 2 and the presser conveyor 3 are not limited to the illustrated belt type, but may be of other types such as a slat type or a net type. In addition, if a belt-type lifting platform is used, as shown in FIG. 6, a conveyor belt provided with a guide 79 with a single-shaped cross section along its length can further reliably prevent meandering. , which is convenient. Furthermore, although a belt transmission mechanism is adopted in the conveyor 2, presser conveyor 3, and swinging device 5, the types of belts are flat belt, round belt,
■A belt or the like is optional, or other transmission mechanism such as a chain transmission mechanism may be used. In addition, in the above,
Although each vibrating cutter 4 is arranged diagonally to improve its sharpness, it may also be arranged vertically.

As explained above, the cutting device for bread, processed meat products, etc. of the present invention has a vibration cutter attached to a transfer device that transfers the object to be cut, such as a loaf of bread or a processed meat product, while maintaining its posture. The cutting edge of the vibrating cutter is disposed so as to face the transport direction of the object to be cut, and the vibrating cutter is provided with a swinging device that swings the cutting edge in the vibration direction, so that the cutting edge of the vibrating cutter is simultaneously subjected to high-speed i-vibration. Since the vibration cutter cuts the object by applying speed fluctuations, the sharpness of the cutting edge of the vibrating cutter increases, the generation of chips is reduced, and the life of the cutting edge is extended, making it easier to replace it. The amount of power required to operate the device is also significantly reduced compared to the conventional method. Further, since the object to be cut is always maintained in its position by the transfer device during cutting, the object to be cut does not shift or float, and accurate cutting is possible.
