The present invention relates to a method and a device for forming a food product, and more specifically, to a method and a device for easily forming a food product having a good appearance and a good shape in response to a change in a weight of the food product, when a bar-like food item is cut to form the food product, or when a periphery of a thin-piece outer material is sealed above an inner material after the inner material has been disposed on an upper surface of the thin-piece outer material to form the food product.
A device and a method for cutting a bar-like food item to form a food product have been variously suggested. A method disclosed in the Patent Publication 1 indicated below is a method for encrusting a multi-layer food product by cutting it so that an encrusting condition of its outer skin material is adjusted. When such a multi-layer bar-like food item is cut to be encrusted, a narrowing speed and a narrowing start timing of a cutting and forming gate surrounded by a cutter body rotatably provided in a cutting mechanism are adjusted by controlling a rotation of the cutter body. A relative speed between an extruding speed of the multi-layer bar-like food item and a lowering speed of the cutting and forming gate is adjusted by controlling a vertical-movement speed and a vertical-movement timing of the cutting mechanism.
A device disclosed in the Patent Publication 2 indicated below includes a shutter vertical-movement motor, a shutter opening/closing motor, a receiving member vertical-movement motor, and a motor control unit for controlling these motors, and encrusts an encrusted food product by cutting it, which food product always has the same appearance and the same shape by controlling a rotation of the shutter opening/closing motor so that a closing end position of a shutter is allowed to be always the same even if a closing start position or a closing operation speed of the shutter is changed.
A device disclosed in the Patent Publication 3 indicated below includes a control device for controlling a raising speed and a lowering speed of a receiving member supporting an encrusted food product from its lower side, and encrusts an encrusted food product by cutting it so that a contacting state between a lower surface of a shutter and an upper part of the encrusted food material is controlled and an amount of an outer material lead to a top side of the encrusted food product is controlled.
A device for forming a food product by sealing a periphery of a thin-piece outer material above an inner material after the inner material has been disposed on an upper surface of the thin-piece outer material is described, for example, in the Patent Publication 4 indicated below.
When a bar-like food item is cut to form a food product, or when a periphery of a thin-piece outer material is sealed above an inner material after the inner material has been disposed on an upper surface of the thin-piece outer material to form a food product, a vertical position of a support member with respect to a shutter device is an important element for an appearance and a good shape of the food product, which support member supports the food product from its lower side below the shutter device (and corresponds to a conveyor of the Patent Publication 1, and the receiving member of the Patent Publication 2). For example, when the shutter device performs a cutting operation while it vertically moves with respect to the bar-like food item flowing downwardly from a supply device, the support member vertically moves in synchronization with the vertical-movement of the shutter device to fix an appearance and a good shape of the food product. Thus, when a weight of the food product is changed, it is necessary to change an uppermost position of the support member accordingly.
However, in the devices disclosed in the Patent Publications 1 and 2, the vertical position of the support member is manually changed by checking the food product while it is being cut, so that working efficiency is poor. Further, when it is necessary to change an operation pattern of the support member according to a property of the food product, replacement of a vertical-movement cam is required.
The device of the Patent Publication 3 includes a control actuator for vertically moving a support member (corresponding to the receiving member of the Patent Publication 3), and controls its vertical-movement speed, but it is not considered that a setting operation of a vertical position of the support member is automatically changed in response to a larger or smaller weight of the food product. Again, when the weight of the food product is changed, the vertical position of the support member is changed by an operator by checking the food product.
To solve the above-stated problem, an object of the present invention is to provide a method and a device for easily forming a food product having a good appearance and a good shape in response to a change in a weight of the food product, when a bar-like food item is cut to form the food product, or when a periphery of a thin-piece outer material is sealed above an inner material after the inner material has been disposed on an upper surface of the thin-piece outer material to form the food product, so that a burden on an operator can be decreased and a production efficiency can be enhanced.

The calculation unit may be configured to calculate the vertical-movement pattern of the support member based on the vertical-movement model pattern, the uppermost position, and the lowermost position.
The control device may include an operation control unit for controlling operations of the shutter device and the support device based on a calculation result of the calculation unit.

In the control device, a target weight of the food product is input into the input unit, a supply amount of the bar-like food item supply device is calculated by the calculation unit, and when an actual weight of the food product is input into the input unit, the supply amount is calculated to be changed in response to a difference between the target weight and the actual weight by the calculation unit, and the control device may include a supply device operation control unit for controlling an operation of the bar-like food item supply device according to the changed calculation result.
The forming device may include a bar-like food item supply device which includes a transferring device for transferring a sheet-like outer material, an inner material supply device for supplying an inner material onto the transferred outer material, and a curling device for curling up the outer material from its one side in a width direction around the inner material.
Further, the present invention is directed to a forming method for forming a bar-like food item into a food product, which method includes supplying the bar-like food item downwardly by a supply device, cutting the bar-like food item by a vertically movable shutter device having, a plurality of shutter pieces capable of opening and closing, and controlling a vertically uppermost position of a support member for supporting the food product from its lower side based on an input parameter input into an input unit of a control device.
The input parameter may be a value based on a target weight of the food product and/or a thickness of the shutter piece.
A storage unit of the control device may store an initial setting parameter including a vertical-movement model pattern of the support member, calculate the uppermost position based on the vertical-movement model pattern and the input parameter, and control the vertical-movement of the support member according to a vertical-movement pattern calculated by a calculation unit based on the uppermost position.

The control device may include an operation control unit which controls operations of the shutter device and the support device based on a calculation result calculated at the calculation unit.
The control device may include a memory unit which can store the initial setting parameter, the input parameter, and the calculation result as one memory group, and read out the stored memory group.

Further, since the setting can be easily changed, a burden on an operator can be decreased and a production efficiency can be enhanced.
Referring to
The supply device 3 includes a supply device 11 for the inner material F and a supply device 13 for the outer material D which are disposed at an upper portion of the frame 2, and a combining nozzle 15 disposed at an upper front portion (on the near side in
The shutter device 5 is disposed below the combining nozzle 15, and configured to drive a plurality of shutter pieces 17 to be opened and closed and to be vertically moved, and cut the bar-like food item PB supplied downwardly from the combining nozzle 15 to form a food product P. The shutter device 5 includes a driving mechanism 19 for the opening/closing actions and a driving mechanism 21 for the vertical movement action. The driving mechanism 19 for the opening/closing actions is configured to perform opening/closing the shutter pieces 17 which are annularly arranged, by driving a control motor M5 for the opening/closing actions, such as a servomotor, to open and close an opening 17A defined by the plurality of shutter pieces 17 to cut the bar-like food item PB to form the food product P. The driving mechanism 21 for the vertical action includes a control motor M6 for the vertical action, such as a servomotor, and a crank mechanism, and is configured to vertically move (vertically reciprocate) the plurality of shutter pieces 17 and the driving mechanism 19 for the opening/closing actions by rotating the control motor M6 for the vertical action in a fixed direction via the crank mechanism. A sensor (not shown), such as a proximity sensor, is disposed at an output shaft of the control motor M6 for the vertical action to detect that the shutter device 5 is present at the uppermost position of the vertically reciprocating action. Since a structure of the shutter device 5 is already known, a detailed explanation of the shutter device 6 will be omitted.
The support device 7 is disposed below the shutter device 5 and includes a support member 23 supporting the food product P from its lower side, which food product P is cut from the bar-like food item PB, a support-member vertical-movement mechanism 25 for vertically moving (vertically reciprocating) the support member 23, a transferring conveyor 27, an electric control actuator M7, such as a servo motor, and a motor M8 for driving a conveyor belt.
The support-member vertical-movement mechanism 25 includes a bearing 31 disposed at a lower front side of the frame 2, two cylindrical shafts 32 supported by the bearing 31 to be vertically moved, and a flange 33 attached to a tip of a shaft of the electric control actuator M7. The two shafts 32 are arranged so that axes of the two shafts 32 are vertically arranged parallel to each other, an upper end of the shaft 32 is connected to the support member 23, and a side of the shaft 32 about the middle of the shaft 32 is connected to the flange 33. Thus, the flange 33, the two shafts 32, and the support member 23 are integrally and vertically reciprocated by driving the electric control actuator M7 to extend and retract a shaft of the actuator M7. A position of the support member 23 when the shaft of the electric control actuator M7 is most retracted, namely, the lowest structural position of the support member 23 of the support device 7 (the position of the support member 23 shown in
The transferring conveyor includes a conveyor plate 35, a conveyor belt 36, and a drive pulley 37. The conveyor plate 35 is attached to two shafts extending from the frame 2 to the front side. The conveyor belt 36 is wound around the conveyor plate 35, the drive pulley 37 and the support member 23. Thus, with the vertical reciprocating action of the support member 23, a portion of the conveyor belt 36 located on the support member 23 (or located below the shutter device 5) is also vertically reciprocated. Namely, the support member 23 supports the food product P from its lower side via the conveyor belt 36. The conveyor belt driving motor M8 is configured to drive the conveyor belt 36 via the drive pulley 37. The conveyor belt 36 is configured to transfer the formed food product P in a transferring direction R.
The control device 9 is configured to drive the control motor M5 for opening and closing the shutter device 5, the electric control actuator M7 for the support device 7, and the motor M8 for driving the conveyor belt of the transferring conveyor 27 in synchronization with the rotation of the control motor M6 for raising and lowering the shutter device 5.
The control device 9 also includes a computer etc., specifically, a central processing unit (CPU) 9Z, a ROM 9Y, a RAM 9X, a storage unit (means) 9A, an input unit (means) 9B, a calculation unit (means) 9C, an operation control unit 9D, a memory unit (means) 9E, and a display unit (means) 9F etc., as shown in
In the present description, as shown in
The storage unit 9A is configured to store an initial setting parameter (items) 10A. The initial setting parameters 10A include a plurality of vertical-movement model patterns 10B for the support member 23, a predetermined maximum vertical stroke 10C for the support member 23, and thicknesses T of the shutter pieces which thicknesses are determined according to a type 10N of the shutter piece 17.
Each of the vertical-movement model patterns 10B includes a raising start timing S3, a raising end timing S4, a lowering start timing S5, a lowering end timing S6 for the support member 23 in one cycle of the cutting process, and arithmetic equations of moving trajectories of the support member 23 at the raising and lowering periods. The moving trajectories of the support member 23 during the raising and lowering periods calculated based on the arithmetic equations of the moving trajectories may be straight lines, sine curves, logarithmic curves etc. or combination thereof. The storage unit 9A stores a plurality of vertical-movement model patterns 10B, and one of the plurality of vertical-movement model patterns 10B may be selected according to a property, an appearance, and a shape of the food product.
The maximum vertical stroke 10C may be stored for each of the plurality of vertical-movement model patterns 10B or may be common to the plurality of vertical-movement model patterns 10B. As explained later, the maximum vertical stroke 10C is used as a threshold.
The storage unit 9A stores a plurality of types 10N of the shutter pieces 17, and the thickness T of each type 10N of the shutter pieces 17.
The input unit 9B is, for example, a touch panel, and is configured to input an input parameter (value) 10D. The input parameters 10D include a target weight 10E of the food product P, the type 10N of the selective shutter pieces 17, and the vertical-movement model pattern 10B. The thickness T of the shutter pieces 17 is determined by selecting the type 10N of the shutter pieces 17.
The calculation unit 9C is configured to calculate an uppermost position 10G, a vertical trajectory (vertical-movement pattern) 10H, 10P, and a lowermost position 10M of the support member 23, which are calculation results 10F, by using the initial setting parameters 10A and the input parameters 10D.
The operation control unit 9D includes a support device operation control unit (means) 9G for controlling the operation of the electric control actuator M7 which vertically reciprocates the support member 23 of the support device 7 based on the calculation results 10F calculated by the calculation unit 9C, a supply device operation control unit (means) 9H for controlling the operation of the supply device 3, and a shutter device operation control unit (means) 9K for controlling the operation of the shutter device 5.
The memory unit (means) 9E stores the initial setting parameters 10A, the input parameters 10D, and the calculation results 1014′ as one memory group 10K. The data of the memory group 10K can be read out if necessary.
The display unit 9F displays the initial setting parameters 10A, the input parameters 10D, the calculation results 10F etc., and is, for example, a liquid crystal panel.
In the forming device 1 configured as explained above, the bar-like food item PB is supplied from the supply device 3 downwardly through the shutter device 5 and is supported from its lower side onto the support member 23, the shutter device 5 is capable of vertically moving and including the shutter pieces 17 capable of opening and closing, the support member 23 is capable of vertically moving, and the bar-like food item PB is cut to form the food product P by closing the shutter pieces 17.
A control method of the forming device 1 will be explained.
An operator uses the input unit 9B to select one of the plurality of vertical-movement model patterns 10B and one of the types 10N of the plurality of shutter pieces 17 stored in the storage unit 9A. The operator further uses the input unit 9B to input the target weight 10E of the food product P to be formed.
The calculation unit. 9C calculates the uppermost position 10G of the support member 23 by using the thickness T of the shutter piece corresponding to the type 10N of the selected shutter piece 17, and the target weight 10E of the food product P, as follows.
As shown in
In the present embodiment, a case in which there are two types T1, T2 (T1<T2) of the thickness T of the shutter piece 17 will be explained. In another embodiment, the relationship between the target weight 10E and the uppermost position 10G of the support member 23 may be a quadratic function etc., and there may be three or more types of thickness T of the shutter piece 17.
When the shutter thickness is T1, a relationship between X and Y is that shown in a graph G1 in
Thus, in response to a change in the weight of the food product, the food product can be easily formed to have a good appearance and a good shape, and thus, a burden on an operator can be decreased and a production efficiency can be enhanced.
Next, the calculation unit 9C determines the lowermost position 10M and the vertical-movement trajectories 10H, 10P of the support member 23. In the present explanation, the Y coordinate of the lowest vertical-movement position 10J is set as 0 mm (0 point).
When the vertical-movement trajectories 1011, 10P of the support member 23 are determined, if the uppermost position 10G is relatively high, a time period of vertically moving the support member 23 between the uppermost position 10G and the lowest vertical-movement position 10J would be relatively long so that the production efficiency may be decreased. In particular, when the thickness T of the shutter piece 17 is thin and the target weight 10E of the food product is small, the uppermost position 10G becomes higher and the production efficiency becomes decreased. In such a case, it is preferable that the maximum vertical stroke 10C of the vertical-movement of the support member 23 is previously determined and set as a threshold, a distance between the uppermost position 10G and the lowest vertical-movement position 10J is compared with the threshold, and the lowermost position 10M of the support member 23 is determined in accordance with the result of the comparison.
Firstly, when the uppermost position 10G is relatively low, namely, when the distance between the uppermost position 10G and the lowest vertical-movement position 10J does not exceed the threshold (or is smaller than the maximum vertical stroke 10C), the calculation unit 9C determines the lowermost position 10M of the support member 23 as the lowest vertical-movement position 10J. For example, when the maximum vertical stroke 10C is 60 mm and the uppermost position 10G is 50 mm, the lowermost position 10M is determined as 0 mm, namely, the lowest vertical-movement position 10J (0 point). The calculation unit 9C subsequently determines the vertical-movement trajectory 10H of the support member 23 by applying the uppermost position 10G and the lowermost position 10M to the vertical-movement model pattern 10B (especially, a moving trajectory arithmetic equation) (see
Next, when the uppermost position 10G is relatively high, namely, when the distance between the uppermost position 10G and the lowest vertical-movement position 10J exceeds the threshold (or is larger than the maximum vertical stroke 10C), the calculation unit 9C determines the lowermost position 10M of the support member 23 as a position which is lower than the uppermost position 10G by the maximum vertical stroke 10C. For example, when the maximum vertical stroke 10C is 60 mm and the uppermost position 10G is 70 mm, the lowermost position 10M is determined as a position which is higher than the lowest vertical-movement position 10J (0 point) by 10 mm. In this case, the vertical stroke of the support member 23 corresponds to the maximum vertical stroke 10C. The calculation unit 9C subsequently determines the vertical-movement trajectory 10P of the support member 23 by applying the uppermost position 10G and the lowermost position 10M to the vertical-movement model pattern 10B (especially, a moving trajectory arithmetic equation) (see
As a result, when the distance between the uppermost position 10G and the lowest vertical-movement position 10J is larger than the maximum vertical stroke 10C (or exceeds the threshold), the vertical stroke of the support member 23 is restricted to or does not exceed the maximum vertical stroke 10C. By doing so, it is possible to avoid a decrease in the production efficiency. Further, it is possible to prevent the food product P on the conveyor belt 36 from falling or dropping out due to excess vertical stroke of the support member 23 and large vertical swing of the conveyor belt 36.
The shutter device operation control unit 9K of the operation control unit 9D controls the operations of the shutter device 5. The support device operation control unit 9G also controls the operation of the electric control actuator M7 for vertically moving the support member 23 according to the vertical-movement trajectories 10H, 10P which are finally determined. Further, after the cutting action for the food product P is completed and the support member 23 is lowered to the lowest position, the operation control unit 9D allows the food product P to be transferred in the transferring direction R by driving the conveyor belt driving motor M8 to drive the conveyor belt 36.
Further, the calculation unit 9C of the control device 9 calculates and sets the supply amount of the supply device 3, specifically, the rotational speeds (supply rates) of the screw driving motor M1 and the pump driving motor M2 of the inner material supply device, and the rotational speeds (supply rates) of the screw driving motor M3 and the pump driving motor M4 of the outer material supply device 13, based on the target weight 10E of the food product P input to the input unit 9B. The supply device operation control unit 9H controls and drives each of the motors M1 to M4 of the supply device 3 according to the set rotational speed. After that, the operator measures the actual weight 10L of the food product P and manually inputs it to an input location for the actual weight 101, of the input unit 9B. The actual weight 101, may be automatically measured and automatically input to the input unit 9B. Then, the calculation unit 9C calculates the difference between the target weight 10E and the actual weight 10L and calculates and resets the rotational speed of each of the motors M1 to M4 so that the actual weight 10L comes close to the target weight 10E. The supply device operation control unit 9H controls and drives each of the motors M1 to M4 of the supply device 3 according to the reset rotational speed. Thus, the operation of the operator for adjusting the actual weight of the food product P to the target weight can be made easy and the burden on the operator (worker) can be reduced.
The display unit 9F displays the input parameters 10D, the calculation results 10F etc. The memory unit 9E can store the input parameters 10D, the calculation results 10F etc. as one group 10K, and the control device 9 may read out the one group 10K and use the input parameters 10D, the calculation results 10F etc. contained in the one group 10K, if necessary. The one group 10K preferably includes the target weight of the food product, the thickness of the shutter piece 17, the maximum stroke of the support member 23, the selected vertical model pattern 10B, and the vertical-movement trajectories 10H, 10P.
By performing the above-stated control, the weight of the food product P allows to be easily changed while a good appearance and a good shape of the food product P are maintained, so that the burden on the operator (worker) can be reduced.
The forming device 1 according to the first embodiment of the present invention has been explained, and then, referring to
The supply device 53 includes a transferring conveyor 55 for transferring a sheet-like outer material D in the transferring direction R, an inner material supply device 57 disposed above the transferring conveyor 55 and supplying an inner material F onto the outer material D, and a curling device 59 disposed downstream of the inner material supply device 57 and curling the outer material from its one side by using the inner material as a core material. Then, a bar-like food item PB in which the outer material D covers the periphery of the inner material F is supplied from a downstream end of the transferring conveyor 55 downwardly. The shutter device 5 is disposed below the downstream end of the transferring conveyor 55, and the support device 7 is disposed below the shutter device 5. The support device 7 includes two conveyors arranged in series, namely, a conveyor 41 disposed below the shutter device 5, and a transferring conveyor 43 disposed downstream of the conveyor 41. The support member 23 is defined by a conveyor plate of the conveyor 41. The conveyor 41 (or the support member 23) is configured to be vertically reciprocated by the support member vertical-movement mechanism 25.
Also in the forming device 51 according to the first alternative, similar to the forming device 1 according to the first embodiment, the weight of the food product P can be easily changed while a good appearance and a good shape of the food product P are maintained by controlling the vertical movement of the support member 23 through the support member vertical 10 mechanism 25 by the control device 9, so that the burden on the operator (worker) can be reduced.
Next, referring to
The support device 7 includes two conveyors arranged in series, namely, a conveyor 45 disposed below the shutter device 5 and a transferring conveyor 47 disposed downstream of the conveyor 45, a support member 23 for supporting the food product P from the bottom side, which food product is cut from the bar-like food item PB, and a support member vertical-movement mechanism 25 etc., for vertically moving (vertically reciprocating) the support member 23. The conveyor belt of the conveyor 45 is wound around the support member 23, and a portion of the conveyor belt which is positioned on the support member 23 is vertically reciprocated along with the vertical reciprocation of the support member 23.
Also in the forming device 101 according to the second alternative, similar to the forming device 1 according to the first embodiment, the weight of the food product P can be easily changed while a good appearance and a good shape of the food product are maintained by controlling the vertical movement of the support member 23 through the support member vertical mechanism 25 by the control device 9, so that the burden on the operator (worker) can be reduced.
Explanation of the forming device according to the embodiments of the present invention has been generally done as described above, but the present invention is not limited to the embodiments and it is needless to say that various modifications can be made within the scope of the claims, namely, these modifications fall within the scope of the present invention.
In the above-explained forming device, the vertical-movement of the support member 23 is controlled according to the calculated vertical-movement trajectories 10H, 10P, but after the vertical-movement trajectory of the support member 23 is calculated, the vertical-movement trajectory may be changed and adjusted by inputting different parameters into the input unit 9B during a production process.
Further, the vertical-movement trajectory 10H, 10P of the support member 23 shown in
In the above-explained embodiment, the food product P is explained as an encrusted food product which is made by cutting and encrusting a bar-like food item with the outer material D covering the periphery of the inner material F, but the food product P may be one made by cutting a bar-like food item consisting only of the outer material D. Also in such a food product, the target weight of the food product can be easily changed while a good appearance and a good shape of the food product are maintained.
In the above-explained embodiment, the forming device is explained as one for cutting a bar-like food item into a food product, but it may be one for forming a food product by disposing an inner material on an upper surface of a thin-piece outer material and then sealing a peripheral edge of the thin-piece outer material above the inner material. In this case, the supply device in the forming device 1 according to the above-explained embodiment is changed (refer to the Patent Publication 4 indicated above), and the shutter device is used as a sealing device for sealing a thin-piece outer material with a plurality of shutter pieces, which outer material has an upper surface on which an inner material has been disposed. Also in this forming device, the target weight of the food product can be easily changed while a good appearance and a good shape of the food product are maintained.
In the above-explained embodiment, the support device is explained as a conveyor, but the support device is not limited to such a conveyor and may be a support device with a mechanism (for example, a robot arm) for vertically and horizontally moving a tray supporting member supporting a tray below the shutter device.
In the above-explained embodiment, the operation of the forming device is controlled based on the calculation results, but the calculation results may be displayed, and the setting of the device may be manually changed. Even in this case, it is sufficient to input the calculation results into the input unit as they are displayed on the display unit, so that the operation efficiency can be enhanced more than before.
