[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for receiving products for slicing devices such as ham.

[0002]

2. Description of the Related Art Conventionally, in order to produce sliced ham, bacon and the like, a columnar ham log is used, for example, in Japanese Utility Model Publication No. 62-437.
It is carried out by using a ham slicer shown in No. 48 or the like. That is, a ham log is fed at a constant speed to a cutting blade that is rotating at a constant speed, so that a sliced ham or the like is manufactured by cutting the ham log into a predetermined thickness. Then, the sliced ham and the like that have been cut are collected every predetermined number of sheets and then packaged.

On the other hand, at a predetermined position below the ham slicer, a variable speed discharge conveyor for receiving and carrying out sliced ham cut by a cutting blade and falling is disposed. Then, the discharge conveyor is operated at a low speed while the predetermined number of sheets are being cut by the cutting blade, and then the high speed operation allows the sliced ham or the like to be discharged in a stacked state while gradually shifting the predetermined number.

[0004]

However, in the above-mentioned conventional apparatus, when focusing on each sliced ham laminated in one block, the sliced ham cut later is on top of the sliced ham cut earlier. Since it is placed on, the fall distance becomes shorter later. On the other hand, the speed of the discharge conveyor during stacking is constant. Therefore, the shift amount of each sliced ham becomes shorter the later, and it is difficult (it becomes shorter later) to make a laminated state in which the positions are neatly displaced at regular intervals.

The present invention has been made in view of the above background, and an object of the present invention is to stack products such as sliced ham cut from a raw wood and falling at regular intervals in a laterally staggered state. It is an object of the present invention to provide a method and a device for receiving a product for a slicer such as ham.

[0006]

In order to achieve the above-mentioned object, a method for receiving a product for a slicing device such as ham according to the present invention is cut from a raw material of food such as ham by a rotating cutting blade and dropped. A pair of left and right product receiving plates arranged to be vertically movable and rotatably arranged in a falling state while receiving a predetermined number of the stacked products, the left and right product receiving plates according to the cutting process. By receiving the product that is cut and dropped by the cutting process with the pair of left and right product receiving plates, and the pair of left and right product receiving plates that have received the product are ready for the next receiving process. Simultaneously descending and moving, while rotating the pair of left and right product receiving plates during the descending movement by a predetermined angle, the product that has been cut and received first is cut next. By a predetermined distance moved relative products below were to shift the relative position between the products stacked on the pair of left and right product receiving plate.

As a device suitable for carrying out the above method, a cutting blade and a cutting and dropping side of a slicing device for ham or the like having a supply means for supplying raw wood of food such as ham to the cutting blade. In a product receiving device which is provided and receives a product cut by the cutting blade while stacking a predetermined number of products in the middle of falling, the product receiving device,
A pair of left and right product receiving plates for receiving the product together, a support rod for supporting the product receiving plate, a means for vertically moving the support rod, a means for rotating the support rod, and the pair of left and right product receiving plates. From the time a plate receives the product until the next product is received, the vertically moving means is operated to move the pair of left and right product receiving plates downward, and the rotating means is operated to operate the product. The receiving plate is rotated by a predetermined angle, and a control means for shifting the relative position of the product received this time and the product received next time is provided.

[0008]

[Operation] The product receiving plate is lifted to the uppermost position. In this state, the raw wood is cut by the cutting blade, and the falling products are received on both product receiving plates. Then, the cutting process is sequentially performed, and accordingly, the means for moving up and down is operated to gradually move the product receiving plate downward by a predetermined distance. Further, in synchronization with the downward movement of the product receiving plate, the rotating means is operated to rotate the pair of left and right product receiving plates together by a predetermined angle. This allows
The product receiving plate that received the first product descends and rotates while receiving the next product,
The product received earlier is also located at a position displaced from the position directly below where it is cut and dropped by moving in a predetermined direction. Therefore, the product that is cut and dropped next is stacked in a state in which it is displaced by a predetermined amount on the product that has been cut first and placed on the product receiving plate. In addition, if the product is laminated by the predetermined number (quantity),
By rotating the product receiving plate at a relatively large angle, a group of products is dropped downward while maintaining the laminated state, and then the product receiving plate is raised to prepare for the next reception.

Further, below the pair of rotating belts 2 and 2, a substantially gate-shaped receiving stand 8 is disposed, and in the approximate center of the top surface of the receiving stand 8, the horizontal direction of the tip of the log 7 is provided. A through hole 8a having an orifice 9 serving as a guide member for fixedly guiding is formed. The inner diameter of the orifice 9 is formed to be substantially equal to the outer diameter of the raw wood 7, and the raw wood 7 supplied by the rotary belts 2 and 2 into the central through hole of the orifice 9.
Are supposed to pass through. Then, the raw wood 7 that has passed through the orifice 9 is fixedly guided in the lateral direction by the orifice 9 and cut by the cutting blade 3 arranged below it.

Further, below the position where the raw wood 7 is supplied, there is arranged a conveyor 10 for feeding the ham cut by the cutting blade 3 to the next packaging device or the like. Then, after stacking a predetermined number of hams cut by the cutting blade 3 between the conveyor 10 and the cutting blade 3, the lower conveyor 1
There is provided a product receiving device 11 according to the present invention which is transferred in a state of being stacked on 0.

The product receiving device 11 comprises a conveyor 1
Flat gourd-shaped product receiving plates 12 arranged on both sides of 0
And a first drive device for vertically moving the product receiving plate 12 arranged in the machine body 1, and a second drive device for rotationally driving the product receiving plate 12.

Next, the above two driving devices will be described with reference to FIGS. First, in the first drive device, first, the first drive motor 13 as a power source is arranged on the inner bottom surface of the machine body 1. The first drive motor 13 is composed of, for example, a servo motor capable of forward / reverse rotation and step drive, and its output shaft 13a is rotationally driven via each power transmission belt 14a-14c and pulleys 15a-15e. The force is transmitted to the screw screw shaft 17 arranged below both product receiving plates 12. The screw screw shaft 17 has a lower end that is supported by a bearing portion 1 with respect to a support frame 18 whose lower end is erected from the inner bottom surface of the machine body 1.
8a is rotatably supported, and its upper end is supported by the bearing portion 20a at a substantially central position of the beam portion 20 horizontally arranged in the support frame 18. Accordingly, when the first drive motor 13 rotates in a predetermined direction, the rotational force is transmitted to the pulley 15e fixed to the lower end of the screw screw shaft 17, and the screw screw shaft 17 rotates by a predetermined amount. On the other hand, at predetermined positions of the beam portion 20 and the beam portion 21 arranged in parallel thereabove,
Vertically penetrating guide holes 20b and 21a are formed, and pillars 22 extending vertically are movably inserted in the guide holes 20b and 21a.
3. A top plate 24 is connected and integrated. As a result, a moving frame body 25 having a generally rectangular cross section as shown in FIG. 4 is formed. A screw 26 that is screwed into the screw screw shaft 17 is provided in a through hole formed in the central portion of the bottom plate 23 of the moving frame body 25. Along with the rotation of the rotating screw screw shaft 17, the screw 26, that is, the moving frame body 25, moves the guide holes 20b of the upper and lower beam portions 20, 21.
21a, it is designed to move up and down while maintaining its standing posture.

Further, a rotary cylinder 27 having a downward opening at a central portion thereof is rotatably supported on a top plate 24 of the moving frame 25, and is moved up and down as the moving frame 25 moves up and down. It has become. A support rod 28 is formed upright on the upper part of the rotary cylinder 27, and the above-mentioned gourd-shaped product receiving plate 12 is fixed to the upper end of the support rod 28 via a mounting base 29.

As a result, as the rotary cylinder 27 moves up and down, the product receiving plate 12 also moves up and down. The pair of product receiving plates 12 are vertically moved in synchronization with each other, and the movement is such that the raw wood 7 is cut by the cutting blade 3 and falls and the sliced ham is always received at a constant fall distance. The movable belt 2 moves downward according to the amount of rotation of the rotary belt 2 (cutting thickness of sliced ham), and then moves upward to return to the original position. The control of the movement is performed by the control unit 30 controlling the rotation direction and the rotation amount of the first drive motor 15.

On the other hand, the second drive device for rotating the product receiving plate 12 rotates the support rod 28, which supports the product receiving plate 12, and thus the rotary cylinder 27 in a predetermined direction. The inner side surface of the cylindrical body 27 is spline-coupled to the upper beam portion 21 of the support frame 18 via the bearing portion 21b and is spline-coupled to the spline shaft 32 that is erected so as not to move up and down. It is adapted to rotate with the rotation of the shaft 32.

The lower end of the spline shaft 32 has a beam 2
1, and the pulley 33 is fixed to the protruding portion. Then, as shown in FIG. 2, the first pulley 33 is connected to the second pulley 35 via the first transmission belt 34. A third pulley 36 is fixed coaxially with the second pulley 35, and the second and third pulleys 35, 36 are arranged vertically and rotated at the same angular velocity.

Further, a second transmission belt 38 is provided along with the idle pulley 37 on the third pulley 36, and the second transmission belt 38 and the first transmission belt 3 are provided.
The rotational force of the second drive motor 40 is transmitted to each of the pulleys 33, 35, 36, 37 via 4 and thereby the product receiving plate 12 is rotated in a predetermined direction by a predetermined angle. The second drive motor 40 is also a servo motor that can be intermittently driven at a desired step angle, and its drive is also controlled by the control unit 30.

Next, an embodiment of the product receiving method according to the present invention using the apparatus of the above embodiment will be described. First, the first drive motor 13 is rotated in a predetermined direction to raise both the left and right product receiving plates 12, 12 to the uppermost position. At this time, the two product receiving plates 12, 12 are arranged in a substantially straight line along a direction orthogonal to the conveyor 10.

From this state, the rotary belts 2 and 2 are driven to gradually lower the raw wood 7. Then the descended log 7
The lower end of is cut by the cutting blade 3 to a predetermined thickness, and the falling sliced ham is received on both product receiving plates 12, 12. Then, in synchronization with the cutting process, the first drive motor 13 is rotated by a predetermined angle to lower both product receiving plates 12, 12 by a distance equal to the cutting thickness. As described above, since the descending distance of the product receiving plate 12 can be easily and accurately controlled by the rotation angle of the first drive motor 13, the upper end surface of the product receiving plate 12 or the slice ham loaded on the product receiving plate 12 can be easily controlled. The position of can be always brought close to the cutting blade 3, and the feedback control of the descending distance of the product receiving plate 12 can be followed even when the cutting thickness changes during the cutting process of one raw wood 7. Can be done accurately and accurately.

Here, in the present invention, in synchronization with the downward movement of the product receiving plate 12, the second drive motor 40 is rotated in a predetermined direction by a predetermined angle, and a pair of left and right product receiving plates 1 is provided.
Both 2 and 12 are rotated by a predetermined angle. That is, the second drive motor 40 is rotated in the same direction, but is rotated at a low speed at the beginning of the descending movement, and at a high speed when a predetermined number of sheets are stacked. As a result, as shown in FIG. 5, the product receiving plates 12, 12 that have received the first sliced ham 41 move downward until they receive the next sliced ham and rotate in the direction of arrow A in the figure. The received sliced ham also moves in the direction of arrow B (the conveying direction of the conveyor 10) and is positioned in the state shown by the chain double-dashed line in the figure. Therefore, the sliced ham to be cut next falls to the position shown by the solid line in the figure, and is cut and stacked on the Soil ham placed on the product receiving plate 12 first. As a result, as can be seen from the figure, the sliced hams stacked up and down are displaced from each other in the front-rear direction. In addition, as described above, the cut distance of the sliced ham can always be made substantially the same, so that the product receiving plate 12 can be moved at a low speed (constant).
Even if the is rotating, it is possible to reliably keep the above-mentioned displacement distance constant.

After stacking a predetermined number of sheets, the second servo motor 32 is rotated at a high speed by a predetermined angle to rotate the pair of product receiving plates 12 and 12 by 180 degrees with reference to the product receiving start (uppermost position). As a result, the sliced ham on the product receiving plates 12 and 12 drops onto the conveyor 10 arranged below and is conveyed to the next-stage packaging device while being stacked by the conveyor 10. There is.

After the product receiving plate 12 is thus rotated to drop the sliced ham on the conveyor 10, the first drive motor 13 is reversely rotated to raise the product receiving plate 12 for the next receiving operation. It is designed to serve. During this upward movement, the second drive motor 4
The rotation of 0 is temporarily stopped.

By repeating the above-mentioned operation thereafter, the sliced hams cut by the cutting blade 3 can be accurately and neatly stacked for each predetermined number of sheets and transferred to the belt conveyor 10 while maintaining that state.

In the preferred embodiment, the second drive motor is rotated at a constant low speed when the product receiving plate 12 is moved downward, but it may be intermittently driven or rotated when it is moved upward. Is also good. Further, the slicing device for implementing the present invention is not limited to the above-mentioned configuration, for example, using an involute cutting blade, it may be one that cuts the raw wood only by rotation of the cutting blade, Needless to say, the shape and type (material) of the raw wood are arbitrary. Also, the mechanism is optional as long as the product receiving plate 12 is rotated when it is moved downward. Furthermore, in the above-described embodiment, the pair of product receiving plates 12 has a gourd shape, and one receiving plate is provided with two receiving portions, but the present invention is not limited to this, and one receiving plate is provided on each side. The receiving unit may be set, or the number of sheets may be set to any number such as three or more.

[0026]

As described above, in the product receiving method and device for a slicing device such as ham according to the present invention, since the product receiving plate is rotated by a predetermined angle when the product receiving plate is moved downward, it is dropped first and positioned on the product receiving plate. When the next product is cut and drops, the product to be moved is already moved a predetermined distance and is located at a position displaced from the drop position. Moreover, since the product receiving plate is moved downward according to the cutting process, the dropped distance of the cut product can be kept substantially constant. As a result, it is possible to stack products such as sliced ham that are cut from the raw wood and fall at regular intervals in a sideways state.
