【Example】
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 to FIG. 5 are diagrams for explaining an embodiment of a lightweight foreign matter incinerator according to the present invention.
[0017]
In the food foreign matter removing apparatus 10 shown in FIG. 1, reference numeral 11 denotes a quantitative feeder for quantitatively supplying food 13 to be removed from foreign matter per hour, and the food supplied quantitatively from the discharge port 11 a of the quantitative feeder 11. 13 is carried on the belt conveyor 12 and conveyed. A search coil 15 is disposed in the middle of the conveyance of the food 13, and this search coil 15 generates a magnetic field for inspection to detect metallic foreign substances contained in the food 13 being conveyed.
[0018]
A food sorter 17 is disposed at the conveyance end of the belt conveyor 12. The food sorting machine 17 has a rotating chute 19 , and this rotating chute 19 is controlled by a control device (not shown) by a driving device (not shown) such as pneumatic, hydraulic or electric. Driven to rotate. The rotating chute 19 is held at a position indicated by a solid line when the food 13 contains no metallic foreign matter, and the food 13 conveyed by the belt conveyor 12 passes further through the rotating chute 19 further downstream. It is conveyed to.
[0019]
When the search coil 15 detects a metallic foreign matter contained in the food 13, it is controlled by the control device, and the rotation chute 19 is rotated to the position indicated by the dotted line by the driving device, and the metallic foreign matter is contained. The food 13 is dropped into the foreign substance storage box 20 below the sorter 17. Then, the rotating chute 19 is immediately controlled and driven again to return to the position indicated by the original solid line, and the subsequent food 13 conveyed by the belt conveyor 12 is conveyed downstream.
[0020]
An excitation motor 21 is arranged on the downstream side of the food sorting machine 17, and a thick wire 23 a as shown in FIG. 4 and FIG. net feeder 23 constructed by knitting the cribriform) is provided in a state of being slightly inclined to the extent shown in Figure 1. The net feeder 23 has a large number of sieve-like eyes 23b as shown in FIG. 4, and a large step 24 is provided at the downstream end in the conveying direction as shown in FIG. .
[0021]
The size of the sieve-like eyes 23 b of the net feeder 23 is selected according to the size of the food 13. On the downstream side of the step 24, a net feeder 26 having the same configuration as the net feeder 23 is arranged in parallel with the net feeder 23, and one end thereof is provided at the lower end of the step 24. The net feeders 23 and 26 are made of heat-resistant metal.
[0022]
Side walls 25 that rise higher than the conveyance surface are integrally provided at both ends in the width direction of the conveyance base 31 and the net feeders 23 and 26 of the vibration motor 21 so that the food 13 does not spill out of the foreign matter removing apparatus 10. It has been. The upstream end portions of the net feeder 23 and the side wall 25 are integrally connected to the transport base 31 of the vibration motor 21, and the downstream end portions of the net feeder 26 and the side wall 25 are cantilevered free ends.
[0023]
Below the net feeders 23, 26, a hopper 27 is disposed that receives wastes such as scum of foreign substances falling from the sieve-like eyes 23 b of the net feeders 23, 26.
[0024]
The waste that has fallen into the hopper 27 slides down to the lowest part where the screw feeder 29 is located due to the gradient of the bottom, and the operation of the screw feeder 29 causes the fallen waste to be perpendicular to the direction in which the food 13 is conveyed. It is conveyed and discharged to the outside of the foreign matter removing apparatus 10 from the discharge port 29b. The screw feeder 29 is actuated by turning a handwheel 29a. The hopper 27 and the screw feeder 29 constitute waste discharging means.
[0025]
Two gas burners 9 a and 9 b are provided below the net feeders 23 and 26 and inside the hopper 27. The gas burner 9 a is disposed on the upstream side of the step portion 24, and the gas burner 9 b is disposed on the downstream side of the step portion 24.
[0026]
A position opposed to the gas burner 9a is above the net feeder 23 is arranged infrared heater 14a, the same position opposed to the gas burner 9b above the net feeder 26, an infrared heater 14b is disposed ing. On the downstream side of the net feeder 26 and the hopper 27, a belt conveyor 30 for conveying the food 13 from which foreign matters have been removed to the next process is disposed.
[0027]
As shown in FIG. 2, the excitation motor 21 is provided with a transport base 31 at the top, and a vibration body 33 is integrally provided below the transport base 31. A stationary body 37 that is provided integrally with the mounting base 35 is disposed below the body to be excited 33. Both end surfaces of the vibrating body 33 and the stationary body 37 are formed obliquely with respect to the vertical direction, and both end portions of the leaf spring 39 are fixed to the both end surfaces by bolts 40. On the stationary body 37, an electromagnet 43 is supported by the bracket 41. Under the vibrating body 33, a magnetic band member 45 that is attracted when the core 43a of the electromagnet 43 is magnetized is provided.
[0028]
In such a vibration motor 21, when the electromagnet 43 is turned on and off, the magnetic band member 45 is attracted to and moved away from the core 43 a of the electromagnet 43 and reciprocates in the direction of arrow A. Therefore, the vibrating body 33 is vibrated by being reciprocally moved in the left-right direction in the figure integrally with the belt magnetic member 45 while being connected to the leaf spring 39.
[0029]
At this time, the plate spring 39 swings in the direction of arrow B with the fixed end on the stationary body 37 side as a fulcrum, and vibrates in small increments. As described above, since the vibrating body 33 vibrates through the swing of the leaf spring 39 provided obliquely, the vibration amount at that time has a vertical component in addition to a horizontal component. .
[0030]
For this reason, as shown in FIG. 1, when the vibration motor 21 is arranged and operated so that the transport table 31 is slightly inclined, the food 13 on the transport table 31 is moved to FIG. As indicated by the broken arrow, the sheet can be conveyed so as to jump on the conveyance table 31.
[0031]
Then, by connecting the transport base 31 of the vibration motor 21 to the upstream end of the net feeder 23, the net feeders 23 and 26 also perform the same movement as the transport base 31, so that the food 13 on the net feeder 23 is also thereon. It can be transported in a jumping manner.
[0032]
As shown in FIG. 3, the gas burner 9a extends over almost the entire width of the net feeder 23 in a direction perpendicular to the transport direction, and a plurality of flames L are emitted from a plurality of holes. The gas burner 9a can move up and down (+ E) or move away (−E) from the net feeder 23 by a driving device (not shown). The gas burner 9b is configured similarly to the gas burner 9a.
[0033]
Also, the infrared heater 14a on the net feeder 23 extends over almost the entire width of the net feeder 23, and can be moved up and down (+ F) by moving toward or away from the net feeder 23 (+ F) by a driving device (not shown). Yes. The infrared heater 14b is configured similarly to the infrared heater 14a.
[0034]
Next, the operation of the food foreign matter removing apparatus 10 according to the embodiment will be described. The food 13 put in the fixed quantity feeder 11 is quantitatively supplied onto the belt conveyor 12 from the discharge port 11a. The food 13 conveyed by the belt conveyor 12 is magnetically inspected by the search coil 15 in the middle of conveyance, and when the food 13 contains no metallic foreign matter, it passes from the belt conveyor 12 via the rotating chute 19. Then, it is supplied onto the conveyance table 31 of the vibration motor 21.
[0035]
When the search coil 15 detects that a metallic foreign substance is contained in the food 13, the rotating chute 19 is rotated by the control means and the driving means and is arranged at the position indicated by the dotted line. For this reason, the conveyance path is interrupted, and the food 13 containing metallic foreign matters falls from the end portion of the belt conveyor 12 and is stored in the foreign matter storage box 20. In this way, the food 13 is sorted by the food sorter 17 depending on the presence or absence of metallic foreign matter inside, and the food 13 containing metallic foreign matter inside can be removed from the conveyance path.
[0036]
The food 13 transported on the transport base 31 of the vibration motor 21 is provided with the vibration motor 21 tilted slightly, so that the operation causes the micro vibration amount in the vertical direction and the micro vibration in the horizontal direction as described above. It is conveyed to the downstream side and sent to the net feeder 23 so as to jump finely by the amount of the component.
[0037]
Since the net feeder 23 is integrally connected to the conveyance base 31 of the vibration motor 21, the food 13 on the net feeder 23 jumps to the downstream side in the same manner due to vibration caused by the operation of the vibration motor 21. It will be transported.
[0038]
The food 13 on the net feeder 23 comes to the position where it is burned over the net from below by the flame L of the gas burner 9 while being sent on the net feeder 23, and is irradiated and heated from above by the infrared heater 14a. For this reason, when lightweight foreign matters such as hair are entangled with and attached to the food 13, only the lightweight foreign matters are incinerated by heating from both the upper and lower directions, and the food 13 is heated by heating in order to immediately pass through the position. Large alteration is prevented.
[0039]
At this time, since the food 13 travels so as to jump on the net feeder 23 as described above, there are many occasions when the direction changes in small increments and the foreign matter is exposed in the vertical direction. Further, after the incineration of the foreign matter, the net feeder 23 vibrates, so that waste such as scum drops from the eyes 23b of the net feeder 23 into the lower hopper 27.
[0040]
When the food 13 is further conveyed, the food reaches the step 24, and the food 13 is rotated twice and three times by dropping the step 24 from the top to the bottom. It will be transported to. Then, the food 13 is trapped over the net by the flame L of the gas burner 9b from below during the conveyance, and comes to a position where it is irradiated and heated from above by the infrared heater 14b. At this time, lightweight foreign substances such as hair are attached to the food 13, and the gas burner 9a and the infrared heater 14a, which cannot be incinerated by the previous gas burner 9a, are exposed in the vertical direction, and there are many opportunities for incineration. They are almost completely incinerated and transported again.
[0041]
In this way, lightweight foreign matters such as hair adhering to the food 13 are almost completely incinerated and removed, and the food 13 falls from the conveyance end of the net feeder 26 and is further conveyed to the next process by the belt conveyor 30. Go. Waste such as debris falling into the hopper 27 can be discharged to the outside of the hopper 27 from the discharge port 29b by the screw feeder 29 provided at the lowermost part.
[0042]
When it is determined that the heating power of the gas burners 9a, 9b or the infrared heaters 14a, 14b is weak, the drive unit (not shown) is used to drive them slightly closer to the net feeder 23 as described above. If it is determined that the heating power of the gas burners 9a and 9b or the infrared heaters 14a and 14b is too strong, they can be moved away from the net feeder 23 a little.
[0043]
In the above embodiment, the case where the search coil 15, the food sorter 17, the rotating chute 19, and the foreign matter storage box 20 are used has been described. However, if they are not necessary, they need not be provided. The removal device 10 can be further reduced in size and cost.
[0044]
Moreover, in the said Example, although the case where the infrared heaters 14a and 14b were provided was demonstrated, since it is not necessary to provide them, when the foreign substances of food can be sufficiently removed even if they are not provided, the foreign substance removal apparatus for foods 10 can be further reduced in size and cost.
[0045]
Moreover, in the said Example, although the case where the level | step difference 24 was provided between the net feeders 23 and 26 was demonstrated, when it can change the direction of the foreign material of food enough, it does not necessarily need to provide, You may make it convey only with the one net feeder 23. FIG. Or conversely, a plurality of steps may be provided.
It does not matter whether the food 13 is a finished product or a raw material.
[0046]
Moreover, in the said Example, although the case where the excitation motor 21 used the leaf spring electromagnetic type was demonstrated, you may use other types of excitation motors, such as a vibration motor drive type.
[0047]
Moreover, in the said Example, although the case where the conveyance stand 31 and the net feeders 23 and 26 of the vibration prime mover 21 were arrange | positioned slightly inclined was demonstrated, they do not necessarily need to arrange | position and incline horizontally. Even in this case, the food 13 on the transport table 31 and the net feeders 23 and 26 can be transported by the vibration of the vibration motor 21.
[0048]
In addition, other types of driving means such as an electric type can be used instead of the handwheel 29a .
[0049]
【The invention's effect】
As described above, according to the present invention, since it is dry, there is no need for drying as in the case of wet, and it is easy to remove waste after incineration by the discharging means. By using a plate-like holding member that vibrates without using a conveyor, the size can be reduced, and high processing efficiency can be exhibited at low cost.
