Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a slicer for slicing articles such as half a fish body or sliced beef whose cross section varies depending on the part or position into pieces of approximately the same size and weight.

Conventional Technology and Problems Conventionally, when making a product by cutting a fish such as salmon into halves and slicing them into appropriate sizes as fillets to be sold to general consumers, frozen food manufacturers, school caterers, etc. A craftsman with several years of experience had to use a knife to slice it. Originally, when you watch a craftsman holding half a fish on a cutting board with his left hand and holding a knife in his right hand to make fillets, the board is in a fixed position, but each time he slices the fish, he moves it to the right with his left hand. While doing so, cut with your right hand. At this time, the edge of the knife always appears to be at a certain point on the chopping board.

Taking a hint from this fact, we mechanically decomposed the subtle movements of human hands by assuming the center point of the slice. Human hands can easily perform complex movements, but
Until now, it has not been possible to break this down into a number of motions and then combine them again to obtain the desired composite slice motion by machine.

Also, when a craftsman slices a fish body etc.,
There was also the problem that it was not possible to meet the rapid increase in demand, and that workers were susceptible to physical injuries such as osteoporosis due to the cutting of hard bones.

Means for Solving the Problems In order to solve the above problems, the present invention provides a slicer for slicing products whose cross-sectional dimensions change in the longitudinal direction, such as the half body of a fish, into substantially uniform weights. It has a processing table on which the product can be placed and can be moved along the longitudinal axis of the device passing through the center of the slice, and a turning fork attached to be able to pivot on a horizontal plane about the center of the slice. a fork for tilting the blade which can change its angle with respect to the vertical line of the mounting surface of the processing table and is attached to the fork for rotation; and a fork for tilting the blade which is equipped with a blade and moves the blade in the cutting direction. and a blade moving device attached thereto. The cutter moving device is a mechanical part that is involved in moving the cutter.It consists of a cutter fixed to a cutter mount.When the swing lever is in the upright position, the cutter is above the processing table and the object to be sliced is When the machine comes in on the processing table, it waits with enough time for the cutting edge to not come into contact with the object to be sliced. When the swinging lever falls down due to the retraction action of the cylinder, which will be described later, the cutting edge of the blade moves in an arc shape and descends to the upper surface of the processing table, slicing the object to be sliced on the processing table. A mechanism that moves the blade vertically between the standby position and the slicing position in this manner is referred to as a blade moving device. In addition, there is a presser device that presses the product on the processing table, a presser plate attached to the presser device via a lever, and a presser device that can be rotated in accordance with the angle at which the presser device is rotated in the horizontal plane of the cutter, and that the center of the presser plate is The slicer is characterized by having a fixed pinion and a moving device for the holding device consisting of a driven rack so that the processing table is always on the axis in the moving direction regardless of the turning angle, and furthermore, the holding device is moved according to the magnitude of the tilting angle of the cutter. When the device is operated, the position of the presser device is moved away from and closer to the line where the cutting edge of the cutter touches the processing table, and when the presser device is released and raised to move on to the next slicing operation, the presser device is In order to avoid hitting the cutter, the cutting edge of the cutter should be kept away from the line that touches the processing table, and when pressing the product with a holding device, a follower device should be installed to allow the holding device to press the product after the cutting tool approaches. Also, when the blade moves perpendicular to the cutting edge line to slice the product, the blade stops moving just before the cutting edge touches the processing table surface, and the angle of the cutting tool with respect to the processing table is set at 50°. It is characterized by restarting the movement of the cutter after being pushed to ~90°, and furthermore, the center line of the tilting axis of the cutter is on the same plane as the processing table, and the plane in which the cutting edge line of the cutter moves and the said processing table are It is characterized by matching the line that intersects the top surface.

In FIG. 4, the turning fork 24 is the turning axis 1.
It is fixed to the upper end of the worm wheel 7, and when the worm wheel 16 rotates, it turns together.

A blade tilting fork 25 is attached to the upper ends of both arms of the turning fork 24 via tilting shafts 26 and 27. Here, the tilting shafts 26 and 27 are rotatably fixed to the upper end of the swinging fork 24 and fixed to the blade tilting fork 25 on the other hand. The tilting shaft 27 has an extended length and extends beyond the upper end of the pivoting fork 24, and the rotation center boss portion of the tilting worm wheel 28 is fixed to that portion. or,
A swing pin 32 is provided at the upper end of the blade tilting fork 25,
A cutter moving device constituted by the several parts described above is attached via 33. To put it simply, it has a three-layer structure in the order of the turning fork 24, the blade tilting fork 25, and the blade moving device from the bottom to the top. The slice center point is pivot axis 1
7 is extended upwards and intersects with the mounting surface of the processing table 4. Although the processing table moves in the longitudinal direction, this slice center point always remains at a constant position.
It serves as a reference point.

According to the present invention, a half-body fish is placed as a product on a processing table, its shape and dimensions are three-dimensionally measured and input into a computer, and the processing table is moved by the required amount according to the output signal. While sequentially moving each slice in the longitudinal direction of the fish body, the cutter attached to the rotating fork is sequentially rotated and tilted by the required amount for each slice around the slice center point on the axis in the moving direction of the processing table. , and the blade edge is configured so that it always passes through the center of the slice when it comes into contact with the mounting surface of the processing table, and at the same time, the presser plate is moved every time while avoiding interference with the blade, making it easier for skilled craftsmen to The device realizes a three-dimensional complex motion comparable to the subtle hand movements of a fish, and slices the fish into pieces of almost the same weight and volume from the head to the tail. The slicer of the present invention can be widely used for products having a symmetrical weight distribution in the length direction.

As an example of a slicing operation, consider a situation in which directions for a turning angle, a tilting angle, and a slice timing are given based on commands from a computer.The turning fork 24 turns to the specified position and then stops. At this time, the blade tilting fork 2
5 and the blade moving device are rotating together and waiting. On the other hand, the processing table 4 on which, for example, a fish body 55 to be sliced is placed is also advanced to a position for slicing by the conveyor 3 in response to a command from the computer and is waiting. The accuracy of the stop position at this time determines the accuracy of the weight of each fillet after slicing. Next, the blade tilting form 25 receives a command from the computer, tilts to a required cutting angle, and then stops. At this time, it goes without saying that the entire blade moving device is stopped and waiting at this tilt angle. Here, in response to the command "slice" from the computer, the blade moving device is activated, descends according to the tilt angle of the blade 39, slices the fish body, and returns to the original position to complete one slicing operation. . This series of operations is
Since each operation must be repeated in cycles of 2.0-2.5 seconds, each operation is performed almost simultaneously and in parallel.
