Description

TECHNICAL FIELD The present invention relates to a slicing apparatus for slicing raw wood of ham or bacon to produce sliced food in a shingling state.

For example, when sliced ham is sealed with a packaging film to produce a sliced food, the raw wood of ham is transferred at a constant speed to a cutting blade that rotates at a constant speed and sliced, and the ham is cut into a predetermined shape. After manufacturing semi-finished products of sliced foods stacked in sheets, they are conveyed to a packaging machine by a conveyor.

The semi-finished sliced food transported to the packaging machine is put into the pocket of the lower packaging film and further sealed with the upper film to complete the sliced food.

In recent years, when producing sliced food by the above-described process, a plurality of (for example, three) ham logs are sliced with one cutting blade in order to increase productivity (see Patent Document 1).

Then, the sliced hams are lined up by adjusting the positions in the conveying direction and the direction perpendicular thereto by an automatic inserting device so that the sliced hams can be put into the pockets of the packaging film, and then conveyed to the packaging machine.

When producing the sliced food described above, it is common practice to stack the sliced hams in a shingling state so that the sliced hams are gradually shifted so that they can be easily peeled off at the time of use (see, for example, Patent Document 2).

In order to produce such a shingled sliced food, while the ham is sliced into a predetermined number by the cutting blade, the conveyor for receiving the sliced ham is driven at a low speed to stack the hams while shifting them, and then the conveyor is moved. By driving at high speed, semi-finished sliced food is delivered to the downstream conveyor (see Patent Document 2).

On the other hand, food logs include those with a circular cross section such as roast ham, and those with a flat cross section such as half bacon and some dry-cured hams. For raw wood with a flat cross section such as half bacon, the sliced bacon is shifted in the short side direction to produce a shingled sliced food.

When producing sliced food in a shingling state using a food log with a flat cross section, the log is usually sliced with the long side direction of the cross section facing the horizontal direction, but the log with the same cross section and a circular cross section Compared to , the number of logs that can be sliced at the same time is reduced (for example, 3 logs for a circular shape versus 2 logs for a flat shape), resulting in a decrease in the productivity of sliced food.

On the other hand, if the short side of the cross section is oriented horizontally and the sliced food is stacked while being shifted in the direction perpendicular to the conveying direction, the number of logs that can be sliced at the same time can be increased. , the productivity of sliced food is improved.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a slicing apparatus capable of slicing a food log having a flat cross section with the short side facing the horizontal direction. .

Here, each time the first conveyor receives the food raw wood sliced by the slicer, it moves by a predetermined pitch in a direction orthogonal to the conveying direction, and the food raw wood is stacked on the first conveyor in a shingling state. Preferably a sliced food product is produced.

After the production of the sliced food is completed, the first conveyor returns to the initial position in synchronization with the second conveyor, and transfers the sliced food to the second conveyor during movement. It is preferable to

In addition, when the first and second conveyors return to their initial positions, the movement of both conveyors is stopped, and the sliced food delivered to the second conveyor is placed downstream of the second conveyor. It is preferable to resume slicing the raw food log by the slicer while delivering it to the third conveyor.

Further, it is preferable that a food log having a flat cross section is used as the food log, and the slicer slices the food log with the short side direction of the cross section of the food log facing the horizontal direction.

By using the slicing apparatus according to the present invention, the first conveyor can be used to stack the sliced foods while the short sides of the raw wood are oriented in the horizontal direction and the sliced foods are shifted in the direction orthogonal to the conveying direction. Therefore, the productivity of the sliced food in the shingling state can be improved.

Furthermore, the delivery of the sliced food from the first conveyor to the second conveyor and the movement of the two conveyors to the initial positions are performed simultaneously, and when the conveyors return to the initial positions, the sliced food is immediately delivered. production can be resumed, the operating rate of the equipment can be improved.

<Slicer structure and function>
First, referring to FIGS. 1 and 2, the configuration of the slicer 2 and the function of each part will be described. The slicer 2 is composed of a support station 21 and a slice station 22 installed on a base 20 . The slicer 2 used in this embodiment has a function of slicing three half bacon logs at the same time.

A half bacon log (hereinafter abbreviated as "bacon log") W stored in a support lane 211 provided in the support station 21 is transferred toward the rotary blade 221 of the slicing station 22 as indicated by an arrow, Sliced to uniform thickness.

The sliced bacon falls onto the first conveyor 4 of the conveying means 3, is processed into shingling-state sliced food in cooperation with the slicer 2, and then delivered to the second conveyor 5, and finally It is handed over from the second conveyor 5 to the third conveyor 6 at the same time. Each station will be specifically described below.

The support station 21 is provided with a long guide portion 212 which is inclined on the base 20 by columns 201 and 202. The guide portion 212 accommodates a long bacon log W and has a substantially rectangular cross section. There are three support lanes 211 installed.

The guide portion 212 is provided with a feed member 214 for transporting the bacon log W downward while the upper end portion of the bacon log W is held by the holder 213 . The feed member 214 is moved downward along the guide portion 212 by a driving portion (made up of a motor and a ball screw) 215 attached to the upper end of the guide portion 212 . The amount of movement of the feed member 214 can be adjusted by the controller 23 (see FIG. 3).

The slicing station 22 supported by the pillar 202 includes a disk-shaped rotary blade 221 for slicing the bacon raw wood W, and a rotary blade drive member 222 for revolving the rotary blade 221 while rotating. By rotating and revolving the rotary blade 221 using the rotary blade drive member 222, the raw bacon W transported on the support lane 211 is sliced into a constant thickness. Therefore, the rotary shaft 223 of the rotary blade 221 is rotatably supported at one end of the rotary plate 224 at a predetermined distance from the rotary shaft of the rotary blade drive member 222 .

The operations of support station 21 and slice station 22 are controlled by programs stored in the memory of controller 23 . As shown in FIG. 3, the controller 23 adjusts the operation timing of the motor 26 and the actuator 27 that drive each member based on the output signals of the position sensor 24 and the rotation sensor 25 installed on each member. to realize the operation of

<Structure and Function of Conveying Means>
Next, the conveying means 3 will be explained. As shown in FIG. 2, the conveying means 3 is composed of a first conveyor 4 and a second conveyor 5 having substantially the same construction, and these conveyors 4 and 5 are arranged side by side in the conveying direction.

The first conveyor 4 is constructed by winding a flat belt 41 around a pair of pulleys 43 and 44 attached to the front and rear of a rectangular frame 42 . A rotation drive motor (accommodated in a housing of the slider 46, which will be described later) is attached.

A slider 46 is attached to one side (lower side in the figure) of the frame 42 for transporting the conveyor 4 in a direction (indicated by a white arrow) orthogonal to the conveying direction indicated by an arrow.

As shown in FIG. 1, the slider 46 is mounted on a chassis 30 placed on the base 20 of the slicer 2, and can be horizontally moved by a ball screw (not shown) accommodated in the chassis 30. be. The movement amount and movement speed of the slider 46 are adjusted by the controller 31 by controlling the rotation speed of the motor 34 that rotates the ball screw.

5, each time the first conveyor 4 receives the bacon sliced by the slicer 2, the conveyor 4 is moved by the slider 44 in a direction orthogonal to the conveying direction. It is possible to manufacture the sliced food S in a shingling state in which the sliced bacon is shifted by one pitch.

Similarly to the first conveyor 4, the second conveyor 5 is also constructed by winding a flat belt 51 around a pair of pulleys 53 and 54 attached to the front and rear of a rectangular frame 52. A rotation driving motor (housed in a housing of a slider 56 described later) is attached to the shaft of the pulley 54 via a joint 55 .

Furthermore, a slider 56 is attached to one end of the frame 52 for transporting the conveyor 5 in a direction (indicated by a hollow arrow) perpendicular to the conveying direction indicated by the arrow.

Similarly to the slider 46, the slider 56 can also be moved horizontally by a ball screw (not shown) housed in the chassis 30. It is adjusted by controlling the number of rotations of the motor 34 that causes the rotation.

As mentioned above, the second conveyor 5 also has similar functions to the first conveyor 4, but with different functions. That is, the second conveyor 5 is used to transfer the single-ring-shaped sliced food S produced by the first conveyor 4 to the third conveyor 6 in the shortest possible time. The function of the second conveyor 5 will be detailed later with reference to FIG.

As with the slicer 2 , the operations of each section of the conveyors 4 and 5 are controlled by programs stored in the memory of the controller 31 . As shown in FIG. 3, the controller 31 adjusts the operation timing of the motor 34 that drives each member based on the output signals of the position sensor 32 and the rotation sensor 33 installed on each member to perform the above operations. Realize.

Also, in this embodiment, ball screws are used as means for driving the sliders 46 and 56, but the driving means is not limited to this. For example, a rack and pinion mechanism may be used to drive the sliders 46,56.

Although the third conveyor 6 is not a component of the slicing apparatus 1 according to the present embodiment, it is closely related to the operation of the slicing apparatus 1, so its configuration and function will be briefly described.

The third conveyor 6 receives the shingled sliced food produced by the slicing apparatus 1 from the second conveyor 5 and conveys it toward a packaging machine (not shown) installed downstream. A long flat belt 62 is wound between a pair of pulleys 63 .

The third conveyor 6 is supported by a frame 61 installed on a chassis 60 and driven by transmitting rotation of a motor (not shown) housed in a box 64 to a pulley 63 via a joint 65. be done.

<Manufacturing and transportation of sliced food>
Next, with reference to FIGS. 4 and 5, the production and transportation of sliced food in a shingling state will be described.

FIG. 4 is a flow chart showing each step from manufacturing sliced food in a singling state to delivery to the third conveyor, and FIG. 5 is the operation of the first and second conveyors 4 and 5 in each step described above. It is a figure explaining.

In FIG. 5, dashed lines A and B indicate the range of movement when the first and second conveyors 4 and 5 move in the direction orthogonal to the conveying direction. As shown in FIG. 5A, at the start of operation, the left end of the first conveyor 4 is in contact with the straight line A, and the right end of the second conveyor 5 is in contact with the straight line B. As shown in FIG.

In this state, the slicer 2 starts slicing the bacon log W (step S1). FIG. 5(a) shows a state in which the first sliced bacon S falls onto the first conveyor 4 and is received.

Next, the first conveyor 4 moves rightward by one pitch as indicated by the white arrow under the control of the controller 31 (step S2). After that, the slicer 2 is driven to slice the second bacon, and as shown in FIG. 5(b), the two sliced bacon are placed on the conveyor while being shifted by one pitch.

The slicer 2 and the first conveyor 4 repeat the operations of steps 1 and 2 five times (No in step S3). Then, as shown in FIGS. 5(b) to 5(e), the sliced bacon is stacked in a state of being laterally shifted by one pitch, and the sliced food S in the shingling state is manufactured.

As shown in FIG. 5(e), when the bacon log W is sliced five times (Yes in step S3), the right end of the first conveyor 5 moves to a position where it touches the straight line B, and the second conveyor 5 coincides with the horizontal position.

Next, as shown in FIG. 5(f), the first and second conveyors 4 and 5 move in synchronism to the left end, and while moving, the single ring-shaped single-ring placed on the first conveyor 4 is moved. , is transferred to the second conveyor 5 (step S4).

FIG. 5(g) shows a state in which the sliced food S has been transferred to the second conveyor 5 and the first and second conveyors 4 and 5 have moved to their initial positions, that is, positions in contact with the straight line A. FIG.

As shown in FIG. 2, in this state, the conveyors 4, 5 and 6 are aligned in the direction orthogonal to the conveying direction. The handover is carried out without any problem (step S5).

After that, the second conveyor 5 which has completed the transfer moves to a position where the right end, that is, the right end of the conveyor touches the straight line B, and waits there (step S6).

On the other hand, the controller 31 of the conveying means 3 notifies the controller 23 of the slicer 2 when the first conveyor 4 returns to the left end. At this point, the sliced food S is not placed on the first conveyor 4, so the slicer 2 resumes slicing according to an instruction from the controller 23 (step S1).

The slicing of the bacon log W by the slicer 2 and the production and transportation of the sliced food S by the conveyors 4 and 5 continue (No in step S7), and when the bacon log W is sliced close to the end (Yes in step S7), The driving of the slicer 2 and the conveyors 4 and 5 is stopped, and the production and transportation of the sliced food are completed.

As described above, the slicing apparatus according to the present embodiment adjusts the setting direction of the cross section when producing shingled sliced food using raw wood with a flat cross section such as half bacon. Since the number of raw food logs that can be sliced at the same time can be increased, the productivity of the slicing apparatus can be improved.

Furthermore, in the slicing apparatus according to the present embodiment, the sliced food is manufactured using a set of conveyors that can move in the direction perpendicular to the conveying direction, and the sliced food is sliced in a shingling state without stopping the slicer. Since it can be manufactured continuously, the operating rate of the equipment can be increased.

Specifically, by synchronizing the movement of the two conveyors, the movement of the conveyors to the initial position and the transfer from the first conveyor to the second conveyor can be performed at the same time. Delivery of sliced food can be performed in the shortest time.

In addition, since the sliced food is handed over and the production of the sliced food can be restarted using the vacant first conveyor, the slicer can be operated continuously.

By the way, the production of sliced food in a shingling state can be realized even if the conveying means is composed only of the first conveyor. By adopting such a configuration, the device cost can be reduced.

However, when such a configuration is adopted, the sliced food remains on the conveyor when the conveyor returns to the initial position, and the manufacturing of the sliced food cannot be restarted until the food is transferred to the third conveyor. , the continuous operation of the slicer cannot be realized, and the operating rate of the equipment decreases.

In the present embodiment, the case of producing a sliced food product in a shingling state using a log of half bacon has been described. It can also be applied to the production of shingled sliced food by obliquely slicing a circular food log.
