Description

  The present invention relates to a rice cooking system provided with a moisture removing device and a moisture removing device used in the rice cooking system, and in detail, each step required for rice cooking is performed while conveying a large number of rice cookers along a conveying line. In a rice cooking system, it is related with the rice removing system provided with the moisture removing device which removes the moisture adhering to the lid of the rice cooking pot, and the moisture removing device used for the rice cooking system.

  Various types of rice cooking systems have been proposed as a rice cooking system that conveys a large number of rice cookers along a conveyance line, performs each process necessary for rice cooking at each position of the conveyance line, and cooks each rice cooking pot. In such a rice cooking system, for example, it is necessary to add various seasoning liquids, ingredients, cooked water, etc. into the rice cooker, or to remove the immersion water from the rice cooker, and from the rice cooker being transported through the transport line The removal | desorption operation | work of removing a lid | cover or attaching a lid | cover to a rice cooker again is needed (refer patent document 1, 2). In addition, the rice cooker that has finished cooking is divided into a rice cooker body and a lid, and each is transported to the washing process, but the lid that has finished washing will newly contain rice cooking materials such as rice and rice cooking water. It will be attached again to the cooked rice cooker.

  In such a lid attaching / detaching operation, a lid chuck device using an electromagnet is usually used to temporarily hold the lid and move it in the vertical direction or the horizontal direction. That is, the lid of the rice cooker used in the rice cooking system as described above is normally provided with a flat chucked portion made of a magnetic material at the center, and the chucked portion of the lid chuck device is provided in this chucked portion. By energizing with the electromagnet part approached, the lid is attracted and held by the electromagnetic force generated by the electromagnet, the lid is moved vertically or horizontally, the lid is removed from the rice cooker, or the lid is attached to the rice cooker. Or the lid can be moved to a desired location.

  However, according to the inventor's experience, the lid chuck device used in the rice cooking system is inferior in durability, and the magnetic force generated by the electromagnet is reduced by relatively short use, and the lid is gripped safely and securely. It was often difficult to transport.

  The present invention was made to solve the above-described problems of the prior art, and provides a rice cooking system capable of extending the life of a lid chuck device using an electromagnet used in a rice cooking system. Let it be an issue.

  As a result of intensive efforts to solve the above-mentioned problems, the inventors of the conventional rice cooking system, the lid chuck device using an electromagnet has a relatively short time of use, the magnetic force is reduced and the life is shortened. It was found that the electromagnet portion of the lid chuck device was deteriorated by moisture. And thinking that the moisture may be derived from the moisture remaining on the lid that the lid chuck device adsorbs and grips, in fact, a moisture removing device is arranged upstream of the lid chuck device, the lid of the rice cooker, In particular, the present invention has been completed by confirming that the life of the electromagnet in the lid chuck device is greatly extended by preventing moisture from remaining in the chucked portion.

  That is, the present invention is a rice cooking system that conveys a rice cooker along a conveyance line and performs necessary steps at each position of the conveyance line, and conveys the rice cooker equipped with a lid or lid of the rice cooker. A transport conveyor, a lid chuck device that attracts and grips the lid that is transported by the transport conveyor alone or in a state where it is attached to the rice cooker, and an upstream of the transport conveyor in the direction of travel of the transport conveyor. The above-described problems are solved by providing a rice cooking system having a moisture removing device for the chucked portion of the lid disposed on the side, and a moisture removing device used in the rice cooking system.

  According to the rice cooking system according to the present invention, since the moisture removing device for the chucked portion of the lid is arranged upstream of the lid chuck device in the traveling direction of the transport conveyor, the electromagnet portion of the lid chuck device approaches, When attracted, there is no moisture in the chucked portion of the lid, and even if the lid is attracted and gripped, the electromagnet portion of the lid chuck device does not deteriorate due to moisture.

  In principle, the water removing device used in the rice cooking system of the present invention can have any mechanism and structure as long as the water can be removed from the chucked portion of the lid before the electromagnet portion of the lid chuck device is attracted and held. However, since it is used in a food production line called cooked cooked rice, it is preferable that it does not generate dust and is easy to keep clean. For example, an abutting piece at least the tip of which is disposed above the conveyor is elastic can be preferably used as the moisture removing device. The abutment piece comes into contact with the chucked portion of the lid when the rice cooker lid is conveyed by the conveyer alone or attached to the rice cooker. By transporting the lid further forward in the direction of travel by the transport conveyor, the tip end portion faces the top surface of the chucked portion from the front to the rear in the traveling direction while remaining in contact with the chucked portion. The chucked portion can be drained to remove moisture from the chucked portion.

  Also, for example, by placing a gas nozzle above the transport conveyor and blowing gas from the gas nozzle toward the chucked portion of the lid, the moisture in the chucked portion of the lid is blown, and in some cases, evaporated. You may make it remove a water | moisture content. As the gas, any gas can be used as long as it can blow off moisture and can be evaporated depending on the case. For example, it is preferable to use clean air that is relatively easily available.

  Each of the contact piece and the gas nozzle as described above may be used alone as a moisture removing device, or may be used in combination. In the state where the lid or the rice cooker equipped with the lid is being transported by the transport conveyor, it is preferable to use both in combination from the viewpoint of reliably removing the moisture in the chucked portion of the lid. Is arranged such that at least the tip of the abutting piece is located upstream of the gas nozzle in the direction of travel of the conveyor, and after first draining the portion to be chucked with the abutting piece, the gas nozzle It is preferable that the moisture remaining in the chucked portion is blown off by the gas injected from the substrate and, if necessary, evaporated to make the moisture removal more reliable.

  The abutment piece may be disposed perpendicular to the transport conveyor that transports the lid or the lid mounted on the rice cooker, but is disposed to be inclined toward the upstream side in the traveling direction of the transport conveyor. It is preferable. When the contact piece is disposed to be inclined toward the upstream side in the traveling direction of the conveyor, compared to the case where the contact piece is disposed to be inclined in the opposite direction, or the case where the contact piece is disposed vertically, The resistance force exerted on the progress of the lid attached to the lid or the rice cooker by the tip portion having elasticity increases, thereby enabling more reliable draining. In addition, it is arranged so as to be inclined toward the upstream side in the traveling direction of the conveyor, so that the tip of the contact piece is positioned upstream in the traveling direction of the conveyor. Means that.

  Similarly, the gas nozzle may be disposed perpendicular to the transport conveyor that transports the lid or the lid mounted on the rice cooker, but is inclined toward the upstream side in the traveling direction of the transport conveyor. Preferably it is arranged. When the gas nozzle is disposed to be inclined toward the upstream side in the traveling direction of the transport conveyor, the gas blown from the gas nozzle is transported by the transport conveyor or a lid mounted on the rice cooker Since the air nozzle is blown against the chucked part of the lid in the opposite direction, the gas nozzle is present in the chucked part compared to the case where the gas nozzle is inclined in the opposite direction or the case where it is arranged vertically. It becomes possible to remove the water | moisture content to perform more reliably. Note that the gas nozzle is arranged to be inclined toward the upstream side in the traveling direction of the transport conveyor, so that the gas blown from the central portion of the gas nozzle is transported upstream of the gas nozzle in the traveling direction of the transport conveyor. It means that it is arranged to blow against the chucked portion of the lid on the conveyor or the conveyor.

  In the case where the contact piece and the gas nozzle are inclined as described above, the inclination angle is not particularly limited, but in the case of the contact piece, if the inclination angle is too large, the contact piece and the gas nozzle are attached to the lid or the rice cooker. In the case of a gas nozzle, if the inclination angle is too large, the amount of gas that blows against the chucked portion of the lid may be reduced. Therefore, in the case where the contact piece and the gas nozzle are arranged to be inclined as described above, the inclination angles are preferably 0 degrees or more and 60 degrees or less with respect to the vertical line, and 30 degrees to A range of 50 degrees is particularly preferable. Moreover, when arrange | positioning the said contact piece and the said gas nozzle inclining as mentioned above, it is preferable that both incline the same angle. In addition, the inclination angle of the gas nozzle refers to an angle between the blowing direction of the gas blown from the center of the gas nozzle and the vertical axis.

  It is preferable that the height of the tip portion of the contact piece and / or the height of the gas nozzle is adjustable, and the height of the tip portion of the contact piece or the gas nozzle. If the height of the part to be chucked on the lid carried on the conveyor or the lid attached to the rice cooker changes, the height change can be adjusted. The height of the tip portion of the abutting piece and / or the height of the gas nozzle can be adjusted by following the above, so that the moisture in the chucked portion can always be efficiently removed. .

  According to the rice cooking system of the present invention and the moisture removing device used in the rice cooking system, before the lid chuck device using the electromagnet attracts and holds the lid of the rice cooking pot, the moisture present in the chucked portion of the lid is removed. Therefore, even if the electromagnet part of the lid chuck device contacts the chucked part of the lid and sucks and grips, moisture does not adhere to the electromagnet part, and the life of the lid chuck device using the electromagnet is extended. The advantage that it can be achieved is obtained. According to the rice cooking system of the present invention and the moisture removing device used in the rice cooking system, the lid of the rice cooker is securely and reliably adsorbed and gripped using a lid chuck device using an electromagnet, and the rice cooker is safely and reliably It is possible to obtain an advantage that the lid can be removed, the lid can be attached to the rice cooker, or the lid can be moved to a desired location.

Only an elastic material may be used. As the material having elasticity, rubber or soft resin can be used. It is preferable that the angle of the tip 8a of the contact piece 8 on the upstream side in the transport direction of the lid 1 is an acute angle.

  α is an inclination angle of the contact piece 8 with respect to the vertical line V. The contact piece 8 may be vertical (that is, the angle α is 0 degree). However, in order to contact the chucked part 11 and effectively remove moisture from the chucked part 11, the contact piece 8 is used. Is preferably inclined toward the upstream side in the transport direction of the lid 1, and a preferable range of the angle α is 0 ° ≦ α ≦ 60 °, and more preferably 30 ° ≦ α ≦ 50 °. . The angle α may be changed by an appropriate means. For example, the angle α may be changed by changing the attachment angle of the contact piece 8 to the holding member 6a or changing the attachment angle of the holding member 6a to the main body 6d.

  FIG. 4 is an enlarged view of the second moisture removing device 7. As shown in the figure, a gas nozzle 9 is attached to the tip of the main body 7a of the second moisture removing device 7 so that the angle can be adjusted. The gas nozzle 9 is connected to a gas source (not shown) through the main body 7a. As a gas to be ejected from the gas nozzle 9, any gas may be used in principle as long as it can be sprayed onto the upper surface of the chucked portion 11 to remove moisture, but from the viewpoint of availability. It is preferable to use air, and it is more preferable to use clean dry air.

  The main body 7a of the second moisture removing device 7 is attached to an appropriate fixed portion (not shown) so as to be movable in the vertical direction. As a result, when the lid 1 having a different height of the chucked portion 11 has been conveyed, the position of the gas nozzle 9 in the height direction is appropriately adjusted in the vertical direction as indicated by the arrows in the figure to The blowing strength of the gas to the portion 11 and the blowing range can be adjusted as appropriate.

  β is an inclination angle of the gas nozzle 9 with respect to the vertical line V. The angle β may be 0 degree. However, in order to effectively remove moisture from the chucked portion 11 by blowing gas onto the top surface of the chucked portion 11, the gas ejected from the gas nozzle 9 is allowed to flow through the lid 1. It is preferable to spray on the upper surface of the chucked portion 11 obliquely toward the upstream side in the transport direction, and a preferable range of the angle β formed by the gas nozzle 9 and the vertical line V is 0 ° ≦ α ≦ 60 °, more preferably , 30 degrees ≦ β ≦ 50 degrees.
