Summary of the Invention

Problems to be Solved by the Invention

[0004] The conveyed object (the tray on which the frozen noodles are placed) carried out from such a processing chamber is conveyed to the next process, and in the next process, for example, a de-panning process for separating the noodles from the tray is performed. Generally, when conveying the conveyed object toward the next process, it is carried out from the processing chamber so that the conveying direction coincides with the longitudinal direction of the conveyed object. However, due to various factors, the longitudinal direction of the conveyed object may be inclined with respect to the conveying direction when being carried out from the processing chamber. When the longitudinal direction of the conveyed object is inclined with respect to the conveying direction in this way, there is a possibility that the conveyed object cannot be suitably conveyed toward the next process.

[0005] Even if the longitudinal direction of the conveyed object is made to coincide with the conveying direction, if adjacent trays are too close to each other, when making the longitudinal direction of the conveyed object coincide with the conveying direction, the adjacent trays may interfere with each other, and there is a possibility that the conveyed object cannot be suitably conveyed toward the next process.

[0006] The present invention has been invented to solve the above problems, and when the longitudinal direction of the object to be conveyed is made to coincide with the conveying direction, it prevents adjacent trays from interfering with each other, and an object of the present invention is to provide a conveying device and a conveying method capable of suitably conveying the object to be conveyed toward the next process.

Means for Solving the Problems

[0007] The conveying device according to the present invention that achieves the above object is a conveying device that conveys an object to be conveyed carried out from a processing chamber. The conveying device includes a first conveying conveyor that conveys the object to be conveyed carried out from the processing chamber in the conveying direction and has a width larger than the length in the longitudinal direction of the object to be conveyed, and a second conveying conveyor that is arranged continuously with the first conveying conveyor on the downstream side of the first conveying conveyor and has a width shorter than the length in the longitudinal direction of the object to be conveyed, a third conveying conveyor arranged adjacent to the second conveying conveyor in the width direction, a moving unit that moves the object to be conveyed on the first conveying conveyor by discharging air, so as to move the object to be conveyed from the third conveying conveyor side toward the second conveying conveyor side in the width direction, and a first guide unit provided on the side of the first conveying conveyor where the object to be conveyed is moved by the moving unit. The first conveying speed of the first conveying conveyor is slower than the second conveying speed of the second conveying conveyor, and the second conveying speed of the second conveying conveyor is faster than the third conveying speed of the third conveying conveyor.

Effects of the Invention

[0008] According to the above-described conveying device, since the second conveying speed of the second conveyor is faster than the third conveying speed of the third conveyor, the conveyed object that has reached the second conveyor and the third conveyor is in a state where the longitudinal direction is inclined with respect to the conveying direction, and the longitudinal direction of the conveyed object rotates to coincide with the conveying direction due to the difference in the conveying speeds of the second conveyor and the third conveyor. Further, since the first conveying speed of the first conveyor is slower than the second conveying speed of the second conveyor, when moving from the first conveyor to the second conveyor, the conveyed objects adjacent to each other are separated. From the above, when aligning the longitudinal direction of the conveyed object with the conveying direction, it is possible to prevent the adjacent conveyed objects from interfering with each other and suitably convey the conveyed object toward the next process.

Modes for Carrying Out the Invention

[0010] Embodiments of the present invention will be described with reference to FIGS. 1 and 2. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted. The dimensional ratios in the drawings are exaggerated for the convenience of explanation and may be different from the actual ratios. In the present embodiment, as the object T to be conveyed by the conveying device 1, a tray on which frozen noodles are placed will be described as an example.

[0011] FIG. 1 is a schematic plan view showing a conveying device 1 according to an embodiment of the present invention. FIG. 2 is a view showing a state in which the object T to be conveyed moves downward in the Y direction by the air discharged from the moving part 40 of the conveying device 1 according to the present embodiment. In the following description, the left-right direction in FIG. 1 is referred to as the X direction (corresponding to the conveying direction), and the up-down direction in FIG. 1 is referred to as the Y direction (corresponding to the width direction). In FIG. 1, the back of the paper surface is the lower side in the vertical direction, and the front of the paper surface is the upper side in the vertical direction. Further, in the following description, when the object T to be conveyed in a state where the longitudinal direction is inclined with respect to the conveying direction is rotated so that the longitudinal direction coincides with the conveying direction, it may be described as "correcting the posture".

[0012] As shown in FIG. 1, the conveying device 1 according to the present embodiment conveys the object T to be conveyed, which has been carried out downward in the Y direction from the freezer F, to the right in the X direction. Since a known freezer F can be used as the freezer F, detailed description thereof is omitted here.

[0013] As shown in FIG. 1, the conveying device 1 according to this embodiment includes a first conveying conveyor 10 disposed below the freezer F in the Y direction, a second conveying conveyor 20 continuously disposed on the right side (downstream side) of the first conveying conveyor 10 in the X direction, a third conveying conveyor 30 disposed above the second conveying conveyor 20 in the Y direction, a moving part 40 that discharges air to the conveyed object T moving on the first conveying conveyor 10, a guide part (corresponding to the second guide part) 50 provided downstream of the first conveying conveyor 10, a detection part 60 provided above the guide part 50 in the Y direction, a discharge part 70 provided on the right side of the detection part 60 in the X direction, a side guide (corresponding to the first guide part) 80 provided below the first conveying conveyor 10 and the second conveying conveyor 20 in the Y direction, and a control part (not shown) that controls the operations of the moving part 40, the discharge part 70, and the side guide 80.

[0014] As shown in FIG. 1, the first conveying conveyor 10 conveys the conveyed object T in the rightward direction in the X direction. The first conveying conveyor 10 is provided to extend in the X direction. The first conveying conveyor 10 is, for example, a belt conveyor, but is not limited thereto.

[0015] A first width W1 along the Y direction of the first conveying conveyor 10 is larger than the length L1 in the longitudinal direction of the conveyed object T.

[0016] The first conveying speed of the first conveying conveyor 10 is slower than the second conveying speed of the second conveying conveyor 20. The first conveying speed of the first conveying conveyor 10 is not particularly limited, but is, for example, 20 to 30 m / min.

[0017] As shown in FIG. 1, the second conveying conveyor 20 conveys the conveyed object T downstream. For example, a bread - removing device for removing frozen noodles from a tray is provided downstream of the second conveying conveyor 20. The second conveying conveyor 20 is, for example, a belt conveyor, but is not limited thereto.

[0018] The second width W2 along the Y direction of the second conveyor 20 is smaller than the first width W1. Further, the second width W2 of the second conveyor 20 is larger than the length L2 in the short side direction of the object to be conveyed T. Also, the second width W2 of the second conveyor 20 is shorter than the length L1 in the longitudinal direction of the object to be conveyed T. For example, it is preferable that the second width W2 of the second conveyor 20 is 35 to 45 mm shorter than the length L1 in the longitudinal direction of the object to be conveyed T. The second width W2 of the second conveyor 20 is not particularly limited, but is, for example, 120 mm.

[0019] According to this configuration, as will be described later, the object to be conveyed T whose longitudinal direction is inclined with respect to the conveying direction is arranged not only on the second conveyor 20 but also on the third conveyor 30. Therefore, in the second conveyor 20 and the third conveyor 30, the longitudinal direction of the object to be conveyed T can be rotated so as to coincide with the conveying direction.

[0020] As described above, the second conveying speed of the second conveyor 20 is faster than the first conveying speed of the first conveyor 10, and is preferably a speed of 2 times or more the first conveying speed. Specifically, the second conveying speed of the second conveyor 20 is preferably 40 to 60 m / min.

[0021] As shown in FIG. 1, the third conveyor 30 is provided together with the second conveyor 20 to rotate the object to be conveyed T whose longitudinal direction is inclined with respect to the conveying direction so that the longitudinal direction coincides with the conveying direction. The third conveyor 30 is provided adjacent to the second conveyor 20 in the Y direction. The third conveyor 30 is, for example, a belt conveyor, but is not limited thereto.

[0022] A guide portion 50 is provided above the third conveyor 30 in the vertical direction. As shown in FIG. 2, the length L3 along the Y direction from the upstream end portion 50A of the guide portion 50 to the lower end in the Y direction of the third conveyor 30 is not particularly limited, but is, for example, 80 mm.

[0023] As described above, by setting the second width W2 of the second conveyor 20 to 120 mm and the length L3 from the upstream end 50A of the guide portion 50 to the lower end in the Y direction of the third conveyor 30 to 80 mm, the posture of the conveyed object T of 120 mm × 160 mm can be preferably corrected.

[0024] The third conveying speed of the third conveyor 30 is slower than the second conveying speed of the second conveyor 20. When the second conveying speed of the second conveyor 20 is 40 m / min, the third conveying speed of the third conveyor 30 is preferably 15 to 28 m / min. Here, if the difference between the third conveying speed and the second conveying speed is too small, the conveyed object T cannot be rotated by the speed difference between the second conveying speed and the third conveying speed. Also, if the difference between the third conveying speed and the second conveying speed is too large, the conveyed object T rotates excessively unintentionally, making it difficult to align the longitudinal direction of the conveyed object T with the conveying direction. Note that the preferred values of the speed difference between the second conveying speed and the third conveying speed vary appropriately depending on the size, material, etc. of the conveyed object T.

[0025] Also, when the contact area of the conveyed object T with respect to the third conveyor 30 is relatively large, the conveyed object T is relatively difficult to rotate. Therefore, it is preferable to set the third conveying speed slower and increase the difference between the second conveying speed and the third conveying speed. On the other hand, when the contact area of the conveyed object T with respect to the third conveyor 30 is relatively small, the conveyed object T is relatively easy to rotate. Therefore, it is preferable to set the third conveying speed faster and reduce the difference between the second conveying speed and the third conveying speed.

[0026] As shown in FIG. 1, the moving unit 40 is disposed between the freezer F and the first conveyor 10. As shown in FIG. 2, when viewed from the positive side in the X direction, the moving unit 40 discharges air to the conveyed object T passing through the boundary between the second conveyor 20 and the third conveyor 30, and moves the conveyed object T downward in the Y direction.

[0027] As a means for detecting that the object T to be conveyed passes through the boundary between the second conveyor 20 and the third conveyor 30, there is no particular limitation, but for example, the laser light L (see FIGS. 1 and 2) irradiated by an irradiation unit (not shown) can be used. Specifically, when the laser light L is continuously irradiated and the object T to be conveyed passes through and the laser light L is blocked, it is detected that the object T to be conveyed has notified the boundary between the second conveyor 20 and the third conveyor 30.

[0028] Here, for example, when the moving unit 40 is not provided, the object T to be conveyed in a state where the longitudinal direction coincides with the conveying direction may be moved to the second conveyor 20 and the third conveyor 30 without being moved downward in the Y direction. At this time, the object T to be conveyed in a state where the longitudinal direction coincides with the conveying direction rotates due to the difference in the conveying speeds of the second conveyor 20 and the third conveyor 30, and the longitudinal direction is inclined with respect to the conveying direction, which is not preferable. On the other hand, according to the conveying device 1 according to the present embodiment, since the moving unit 40 is provided, it is possible to prevent the above-described problem from occurring, and the object T to be conveyed can be more suitably conveyed toward the next process.

[0029] However, the object T to be conveyed whose longitudinal direction is inclined with respect to the conveying direction can have its posture corrected by the guide unit 50 so that the longitudinal direction coincides with the conveying direction, and even if the posture cannot be corrected by the guide unit 50, it can be discharged from the second conveyor 20 by the discharge unit 70. Therefore, a conveying device without the moving unit 40 is also included in the present invention.

[0030] Note that the moving unit may be configured to continuously discharge air. With this configuration, the irradiation unit becomes unnecessary, and thus the configuration of the entire conveying device can be simplified.

[0031] As shown in FIG. 1, the guide unit 50 is provided above the third conveyor 30 in the vertical direction, which is downstream of the first conveyor 10. Further, the guide unit 50 is disposed to be inclined with respect to the X direction such that the distance along the Y direction to the second conveyor 20 becomes narrower toward the downstream side.

[0032] Since the guide portion 50 is configured in this manner, it is possible to assist in correcting the posture due to the conveyance speed difference between the second conveyance conveyor 20 and the third conveyance conveyor 30. Further, even if the posture cannot be corrected by the conveyance speed difference between the second conveyance conveyor 20 and the third conveyance conveyor 30, the posture can be corrected by the guide portion 50.

[0033] Further, since the guide portion 50 has the above-described configuration, if the posture cannot be corrected by the conveyance speed difference between the second conveyance conveyor 20 and the third conveyance conveyor 30 and the posture cannot be corrected on the upstream side within the guide portion 50, the object to be conveyed T whose longitudinal direction is inclined with respect to the conveyance direction can be stopped by the guide portion 50 on the downstream side within the guide portion 50.

[0034] The detection unit 60 detects that the object to be conveyed T has stopped in the guide portion 50. The detection unit 60 is a reflection type photoelectric sensor. That is, when the object to be conveyed T is stopped in the guide portion 50, light is transmitted from the detection unit 60, the transmitted light is reflected by the object to be conveyed T, and returns to the detection unit 60, thereby detecting the presence of the object to be conveyed T.

[0035] Note that a transmission type photoelectric sensor may be used as the detection unit. When using a transmission type photoelectric sensor, the light projector is arranged at the same position as the detection unit 60, and the light receiver is arranged on the moving side guide 82 of the side guide 80 described later.

[0036] As shown in FIG. 1, the discharge unit 70 is provided on the downstream side of the detection unit 60. The discharge unit 70 discharges the object to be conveyed T stopped in the guide portion 50 from the second conveyance conveyor 20. The discharge unit 70 discharges the object to be conveyed T from the second conveyance conveyor 20 by blowing air against the object to be conveyed T on the second conveyance conveyor 20. The object to be conveyed T discharged from the second conveyance conveyor 20 is stored in the storage portion A located below the second conveyance conveyor 20 in the Y direction of the moving side guide 82.

[0037] As shown in FIG. 1, the side guide 80 is provided below the first conveyor 10 and the second conveyor 20 in the Y direction. The side guide 80 is provided to guide the conveyance of the object to be conveyed T on the first conveyor 10 and the second conveyor 20. The side guide 80 includes a fixed side guide 81 provided on the upstream side and a movable side guide 82 provided on the downstream side of the fixed side guide 81.

[0038] As shown in FIG. 1, the fixed side guide 81 is provided along the X direction. The fixed side guide 81 is fixedly provided with respect to the first conveyor 10 and the second conveyor 20.

[0039] As shown in FIG. 1, the movable side guide 82 is provided along the X direction. When the discharge unit 70 discharges the object to be conveyed T from the second conveyor 20, the movable side guide 82 can be retracted downward in the vertical direction. The movable side guide 82 is moved up and down by a cylinder (not shown).

[0040] The control unit controls the driving of the moving unit 40, the discharge unit 70, and the movable side guide 82. The control unit is, for example, a CPU.

[0041] Next, with reference to FIGS. 3 to 5, the conveying method of the conveying device 1 according to the present embodiment will be described. In the following description, the operations of various components of the conveying device 1 are performed by the control unit. FIG. 3 is a schematic plan view for explaining the conveying method of the conveying device 1 according to the present embodiment, and shows a case where the longitudinal direction of the object to be conveyed T coincides with the conveying direction. FIG. 4 is a view showing a state in which the object to be conveyed T whose longitudinal direction is inclined with respect to the conveying direction rotates so that the longitudinal direction coincides with the conveying direction on the second conveying conveyor 20 and the third conveying conveyor 30. FIG. 5 is a view showing a state in which the objects to be conveyed T are separated from each other when the three objects to be conveyed T1, T2, and T3 move from the first conveying conveyor 10 to the second conveying conveyor 20. For ease of understanding, FIG. 4 shows a state in which one object to be conveyed T is conveyed, while FIG. 5 shows a state in which three objects to be conveyed T1, T2, and T3 are conveyed.

[0042] The object to be conveyed T frozen in the freezer F moves downward in the Y direction and is moved to the first conveying conveyor 10 as shown in FIG. 1. When the object to be conveyed T comes out of the freezer F, as shown in FIG. 3, the X direction is arranged so as to be the longitudinal direction, and the object to be conveyed T is moved to the first conveying conveyor 10 in a posture where the X direction is the longitudinal direction. Then, the object to be conveyed T arranged so that the X direction is the longitudinal direction moves rightward in the X direction on the first conveying conveyor 10 along the side guide 80 as shown in FIG. 3. Then, the object to be conveyed T is moved to the lower side in the Y direction (side guide 80 side) by the moving unit 40, and moves on the second conveying conveyor without being placed on the third conveying conveyor 30 and without stopping at the guide unit 50, and is conveyed to the next process.

[0043] On the other hand, for various reasons, as shown in FIG. 4, the object to be conveyed T may be moved to the first conveying conveyor 10 in a state where the longitudinal direction of the object to be conveyed T is inclined with respect to the conveying direction (FIG. 4 shows a state where the short side direction of the object to be conveyed T coincides with the conveying direction). The object to be conveyed T whose longitudinal direction is inclined with respect to the conveying direction moves rightward in the X direction on the first conveying conveyor 10 in the same posture as shown in FIG. 4, and is moved to the lower side in the Y direction by the moving unit 40.

[0044] Then, when the object T to be conveyed with its longitudinal direction inclined with respect to the conveyance direction is transferred from the first conveyor 10 to the second conveyor 20 and the third conveyor 30, due to the conveyance speed difference between the second conveyor 20 and the third conveyor 30, the lower side of the object T in the Y direction moves ahead of the upper side in the Y direction and moves to the plus side in the X direction, and is rotated counterclockwise as shown in FIG. 4 so that the longitudinal direction coincides with the conveyance direction. At this time, the guide portion 50 assists the counterclockwise rotation of the object T to be conveyed.

[0045] Here, since the first conveyance speed of the first conveyor 10 is slower than the second conveyance speed of the second conveyor 20, when moving from the first conveyor 10 to the second conveyor 20, as shown in FIG. 5, the objects T to be conveyed adjacent to each other are separated. Therefore, when the longitudinal direction of the object T1 is made to coincide with the conveyance direction by the second conveyor 20 and the third conveyor 30, it is possible to prevent the adjacent objects T1, T2, and T3 to be conveyed from interfering with each other.

[0046] If the posture cannot be corrected by the second conveyor 20 and the third conveyor 30 and / or if the posture cannot be corrected by the guide portion 50, the guide portion 50 stops the movement of the object T to be conveyed in the rightward direction in the X direction.

[0047] Then, the detection unit 60 detects that the object T to be conveyed has stopped in the guide portion 50.

[0048] Then, when the control unit receives a signal from the detection unit 60 confirming the presence of the object T to be conveyed, it transmits a signal to the cylinder that drives the moving side guide 82 to retract the moving side guide 82 downward in the vertical direction. Further, the control unit transmits a signal to the discharge unit 70, and the discharge unit 70 blows air against the object T to be conveyed to discharge it from the second conveyor 20.

[0049] When the detection unit 60 stops detecting the object to be conveyed T, it is assumed that the jamming of the object to be conveyed T has been resolved. The air of the discharge unit 70 stops, and the moving side guide 82 moves upward in the vertical direction.

[0050] As described above, the conveying device 1 according to the present embodiment is a conveying device that conveys the object to be conveyed T unloaded from the freezer F to the next process. The conveying device 1 conveys the object to be conveyed T unloaded from the freezer F in the conveying direction, and includes a first conveying conveyor 10 having a width W1 larger than the length L1 in the longitudinal direction of the object to be conveyed T. Downstream of the first conveying conveyor 10, a second conveying conveyor 20 that is continuously arranged with the first conveying conveyor 10 and has a width W2 shorter than the length L1 in the longitudinal direction of the object to be conveyed T, and a second conveying conveyor 20. And a third conveying conveyor 30 arranged adjacent to each other in the width direction of the second conveying conveyor 20. The first conveying speed of the first conveying conveyor 10 is slower than the second conveying speed of the second conveying conveyor 20, and the second conveying speed of the second conveying conveyor 20 is faster than the third conveying speed of the third conveying conveyor 30. According to the conveying device 1 configured as described above, since the second conveying speed of the second conveying conveyor 20 is faster than the third conveying speed of the third conveying conveyor 30, the object to be conveyed T that has reached the second conveying conveyor 20 and the third conveying conveyor 30 is in a state where the longitudinal direction is inclined with respect to the conveying direction. Due to the difference in the conveying speeds of the second conveying conveyor 20 and the third conveying conveyor 30, the object to be conveyed T rotates so that the longitudinal direction of the object to be conveyed T coincides with the conveying direction. Further, since the first conveying speed of the first conveying conveyor 10 is slower than the second conveying speed of the second conveying conveyor 20, when moving from the first conveying conveyor 10 to the second conveying conveyor 20, the objects to be conveyed T adjacent to each other are separated from each other. From the above, when the longitudinal direction of the object to be conveyed T is made to coincide with the conveying direction, it is possible to prevent the adjacent objects to be conveyed T from interfering with each other and to suitably convey the object to be conveyed T toward the next process.

[0051] Further, the conveying device 1 further has a moving unit 40 that moves the object to be conveyed T, which moves the first conveying conveyor 10, by discharging air against the object to be conveyed T, so as to move the object to be conveyed T to the opposite side of the freezer F in the width direction. According to the conveying device 1 configured in this way, the object to be conveyed T can be conveyed more suitably toward the next process.

[0052] Further, the conveying device 1 further has a guide unit 50 that is provided downstream of the first conveying conveyor 10 and that aligns the longitudinal direction of the object to be conveyed T with the conveying direction when the object to be conveyed T comes into contact therewith. According to the conveying device 1 configured in this way, when correcting the posture of the object to be conveyed T by the second conveying conveyor 20 and the third conveying conveyor 30, the posture of the object to be conveyed T can be additionally corrected by the guide unit 50. Further, if the posture of the object to be conveyed T cannot be corrected by the second conveying conveyor 20 and the third conveying conveyor 30, the posture of the object to be conveyed T can be corrected by the guide unit 50.

[0053] Further, the conveying device 1 further has a detection unit 60 that detects the object to be conveyed T stopped in the guide unit 50 and a discharge unit 70 that discharges the object to be conveyed T stopped in the guide unit 50 from the second conveying conveyor 20. According to the conveying device 1 configured in this way, when the postures of the object to be conveyed T cannot be corrected by the second conveying conveyor 20, the third conveying conveyor 30, and the guide unit 50, the object to be conveyed T with its longitudinal direction inclined with respect to the conveying direction is stopped by the guide unit 50, and the object to be conveyed T stopped in the guide unit 50 can be discharged from the second conveying conveyor 20 by the discharge unit 70. Therefore, the object to be conveyed T can be conveyed more suitably toward the next process.

[0054] Also, the second conveying speed of the second conveyor 20 is two times or more the first conveying speed of the first conveyor 10. According to the conveying device 1 configured in this way, when switching from the first conveyor 10 to the second conveyor 20, the conveyed objects T adjacent to each other are more suitably separated, and when aligning the longitudinal direction of the conveyed object T with the conveying direction, it is possible to reliably prevent the conveyed objects T adjacent to each other from interfering with each other.

[0055] Note that the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.

[0056] For example, in the above-described embodiment, air is used for the discharge unit 70, but the discharge unit may mechanically discharge the conveyed object T.

[0057] Also, in the above-described embodiment, air is used for the moving unit 40, but the moving unit 40 may mechanically move the conveyed object T.

[0058] Also, in the above-described embodiment, the conveying device 1 has the guide unit 50, but the guide unit 50 may not be provided.

[0059] Also, in the above-described embodiment, the conveying device 1 is provided with the detection unit 60 and the discharge unit 70, but the detection unit 60 and the discharge unit 70 may not be provided.

However, the conveyed object is not limited to this, and it may be any object as long as the lengths in the longitudinal direction and the lateral direction are different from each other.

[0061] Also, in the above-described embodiment, the freezer is given as an example of the processing chamber, but the processing chamber for processing food is not limited to the freezer, and it may be a thawing chamber, a heating chamber, or the like.
