Description

  The present invention relates to a mouth opening device in which an opening is opened in order to pack an appropriate food material in a bag-like food such as fried chicken.

In order to pack sushi rice or other appropriate food into a bag-like food such as fried fried food, it is necessary to perform a mouth opening operation with an incision part put in one end of the fried food as an opening, but facing the vicinity of the opening There are many cases where the inner surfaces are in close contact, and when the mouth is opened from above and below by mechanical or manual work, there is a situation in which a crack is generated or broken by the gripping nail near the opening. The loss of bag-like foods such as deep-fried fries came out at a rate of.

  In addition, since there is a tendency that a thick and soft food is preferred in recent years as a bag-like food such as deep-fried food, a bag-like food is often used when stuffing ingredients inside such a thin bag-like food. Breaking was even more problematic.

  For example, in Patent Document 1, as a method of supplying sushi rice to the inside of a deep-fried food, a gripping claw that descends from above the deep-fried food and a gripping claw that rises from below the deep-fried food simultaneously grip the cut portion of the deep-fried food. An invention is described in which each of the holding claws and then each gripping claw performs the reverse action to open the cut portion of the fried chicken.

  Moreover, in patent document 2, it has an adsorber which adsorb | sucks close to suction of air at the upper side and the lower side of a bag-shaped food product, respectively, hold | maintains the upper side and lower side of a bag-shaped food product with both adsorbent tools, and then bag-shaped food product An invention is disclosed in which only the suction tool abutting on the upper side is moved upward to open the cut portion of the fried chicken.

  Since the invention described in Patent Document 1 is a device that grips the upper and lower sides of the frying with gripping claws, if the thickness is thick and soft relative to the frying area, the tip of the metal gripping claws that lifts upward Then, the weight of the upper surface side of the deep-fried food is concentrated on the deep-fried food that is caught, and it is easy to break. In addition, since the lower surface side of the fried chicken is lowered downward by the gripping claws, there is a risk that it will be broken during the movement.

  Further, in the invention described in Patent Document 2, since the upper and lower sides of the frying are opened by suction of the suction portion, two intake or exhaust devices respectively corresponding to the upper suction portion and the lower suction portion are provided. It is necessary to use a high-capacity device even if the pipes extending from the upper adsorbing portion and the lower adsorbing portion are integrated on the way and the intake or exhaust device is used as one unit, which requires installation space. Further, when two intake or exhaust devices are provided, it is necessary to adjust the upper side and the lower side of the frying so as to have the same suction force.

  Therefore, in the present invention, when opening an opening for filling an appropriate food material into a thick and soft bag-like food such as fried chicken, the bag-like food is prevented from cracking or breaking, and further used as an intake or exhaust device An object of the present invention is to provide a mouth-opening device for bag-shaped foods that can reduce the volume or the capacity.

  That is, the present invention is an apparatus for opening a mouth to pack a suitable food material into a thick and soft bag-shaped food, and when the bag-shaped food is placed, the upper surface of the bag-shaped food is sucked into the air. An adsorbing tool that adsorbs the bag-like food, and a gripping tool that holds the lower surface of the bag-like food. The adsorbing tool and the holding tool hold the upper and lower surfaces of the bag-like food with the adsorbing tool and the holding tool. Bag-like food opening device having a control means for opening the bag-like food by separating the bag-like food, and having a mesh-like structure attached to the lower surface portion of the adsorber that contacts the upper surface of the bag-like food It is.

  Then, with the upper and lower surfaces of the bag-like food being held by the adsorber and the gripper, the adsorber is moved upward, and the adsorber and the gripper are separated without moving the gripper downward. It is something to be made.

  The adsorbing tool has at least two air holes.

  And it has a notch in the blade edge | tip of the grip tool contact | abutted with the lower side of a bag-shaped foodstuff.

  When the bag-like food of the present invention is placed, the bag-like food has an adsorber that adsorbs to the upper surface of the bag-like food by suction of air, and a gripper that holds the lower surface of the bag-like food. And holding the upper and lower surfaces of the bag-shaped food with the control means for opening the bag-shaped food by separating the adsorber and the gripping tool, and adsorbing the upper surface of the bag-shaped food If the lower surface of the utensil has a mesh-like structure, the upper side of the thick and soft bag-like food will be adsorbed to the entire mesh-like structure disposed on the lower surface of the adsorbing tool with equal force. No cracks or breakage on the upper side of the bag-like food. Further, since the adsorber is only above the bag-like food, it is only necessary to install one intake or exhaust device, and the entire device can be miniaturized.

  Then, with the upper and lower surfaces of the bag-like food being held by the adsorber and the gripper, the adsorber is moved upward, and the adsorber and the gripper are separated without moving the gripper downward. Then, the gripping tool that grips the lower surface of the bag-like food only grips the lower surface of the bag-like food, and the force that pulls the lower side of the bag-like food downward does not work. No damage will occur.

  If the adsorber has at least two air holes, the pulling force on the upper surface of the bag-shaped food becomes even, so that the upper surface of the bag-shaped food does not crack or break.

  And if there is a notch in the blade edge of the gripping tool that comes into contact with the lower surface of the bag-like food, even if the upper surface of the bag-like food is lifted upward by the adsorber, the edge of the gripping tool will easily bite into the lower surface of the bag-like food. The lower surface of the bag-like food can be held with less force, making it difficult to cause cracks and breakage, and the bag-like food is not lifted upward and does not fail to pack the food to be packed inside the bag-like food.

  Hereinafter, an embodiment relating to a bag-like food opening device according to the present invention will be described with reference to the drawings. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is a side view when the opening (11) of the bag-shaped food (1) is opened by the bag-type food mouth opening device of the embodiment of the present invention, and FIG. 2 is this bag-shaped food. FIG. 3 is a perspective view of the adsorbing tool (2) used in the bag-shaped food opening device, and FIG. 4 is the bag-shaped food opening. Fig. 5 is a perspective view of a gripping tool (3) used in the apparatus, and Fig. 5 is a perspective view of a production line for sushi that uses this bag-like food opening device.

  The mouth-opening device for bag-shaped food of the present invention is provided with an upper plate (4) that can be raised and lowered with respect to the lower plate (5), and an adsorber ( 2), the grip (3) is attached below the lower plate (5).

  The thick and soft bag-like food (1) is a fried chicken for bag-shaped inari sushi having an opening (11) on the left end side of the bag-like food (1) shown in FIG. This bag-shaped food (1) is a deep-cut square tofu fried in oil, a needle is inserted into this, air is put into a bag shape, excess oil is removed, and the upper surface is cut by the center. The side portion and the lower surface side are divided into two, and the cut portion becomes the opening (11). The bag-like food (1) can be appropriately seasoned.

  The suction tool (2) has a substantially elliptical shape as shown in FIG. 3, and a metal mesh (21) is disposed on the lower surface thereof, and the inside is hollow from the metal mesh (21). There are two vent holes (22). The two vent holes (22) are connected as one pipe inside the adsorber (2), and have a hollow suction cylinder (6), a valve for adjusting intake and exhaust (not shown), and another hollow pipe. After that, it is connected to an exhaust device (not shown). Air is sent to a pipe connected by an exhaust device (not shown) by exhausting air and a valve having a three-way for adjusting intake and exhaust. When the operation is controlled by the control and the valve is adjusted so that air is discharged to the outside from the second path of the valve, the inside of the suction cylinder (6) connected to the third path is depressurized. Thus, the suction tool (2) connected to the suction cylinder (6) can suck up the bag-like food (1). On the other hand, when the valve is adjusted so that air is discharged from the third path of the valve, the air is sent into the suction cylinder (6) connected to the third path, and the suction cylinder The adsorber (2) connected to (6) releases the bag-like food (1) downward.

  Then, when the bag-like food (1) comes into direct contact with the vent hole (22), the wire mesh (21) is attached to a part of the bag-like food (1) attached to the ridge around the vent hole (22). It is a network structure provided to prevent stress from being concentrated and easily broken, and to be adsorbed with a uniform force on the lower surface of the adsorber (2), and is made of stainless steel. In addition, the mesh structure is not particularly limited in shape to a mesh, and may include a punching metal obtained by drilling a large number of pores in a metal plate. Furthermore, the material is not particularly limited to metal, and a polymer material such as polypropylene, polyethylene, polyethylene terephthalate, or fluororesin can be used alone or in combination of two or more as a network structure.

  The number of meshes in the mesh structure, that is, 1 inch (25.4 mm) is preferably 3 to 200, more preferably 5 to 100. When the mesh of the mesh-like structure is less than 3, stress due to suction concentrates on a part of the bag-like food (1) that comes into direct contact with the mesh ridges and is easily broken. On the other hand, when the mesh of the mesh-like structure is larger than 200, the force for sucking the bag-like food (1) becomes weak, and it becomes difficult to suck the bag-like food (1) sufficiently.

  The gripping tool (3) has a shape like a nail-cutting blade so that the two cutting edges (32) having the notches (31) face each other and close when the cutting edges (32) come into contact with each other. The gripping tool (3) is controlled by electronic control by a gripping tool actuating device (not shown), and the lower plate hole (51) provided in the lower plate (5) is connected to the suction tool (2) and the gripping tool (3 ) Is moved upward when it comes to the line connecting, and the lower surface of the bag-like food (1) is controlled through the lower plate hole (51).

  As shown in FIGS. 1 and 4, the upper plate (4) has a suction cylinder (6) connected to the suction tool (2), and a bolt connected to the food presser plate (7). Is fixed with a nut. The upper plate (4) is provided so as to be able to move up and down with respect to the lower plate (5), and the lifting operation is controlled by electronic control.

  The lower plate (5) has an elongated plate-like shape, and has a plurality of lower plate holes (51) obtained by perforating the lower plate (5) in an elliptical shape at equal intervals in the longitudinal direction. Between the lower plate holes (51), a rod-like partition having round ends is provided in the width direction. Moreover, a lower board (5) can move to a longitudinal direction, and can convey the some bag-like food (1) mounted so that a plurality of lower board holes (51) may be covered continuously. The operation is controlled by electronic control so that it can be performed.

  The food presser plate (7) has a shape like a car stop block that gradually rises in a direction from one end to the other end of the upper surface of the flat plate. A bolt is screwed onto the raised upper surface. The lower surface of the food presser plate (7) is provided at the same height as the lower surface of the adsorbing tool (2), and the lower plate hole (51) together with the lower surface of the adsorbing tool (2) by lowering the upper plate (4). The upper surface of the bag-like food (1) placed on the surface can be pressed, and when the bag-like food (1) is not placed on a flat surface, such as part of the bag-shaped food (1) being raised, Can be modified to place.

  And this opening device for bag-shaped foods performs the opening operation | work of bag-shaped food (1) by the process as shown below.

  First, as shown in FIG. 2A, the gripping tool (3) is raised in the lower plate hole (51) to a position where the cutting edge (32) contacts the bag-like food (1).

  Next, as shown in FIG. 2 (b), the upper plate (4) is lowered until the adsorber (2) and the food presser plate (7) are in contact with the upper surface of the bag-like food (1), and then adsorbed The valve is adjusted so that the tool (2) sucks air, and at the same time, the opposing cutting edge (32) of the gripping tool (3) is closed and the lower surface of the bag-like food (1) is gripped.

  A wire mesh (21) is disposed on the lower surface of the adsorber (2), and the upper surface of the bag-like food (1) is adsorbed to the entire wire mesh (21) with an equal force. There is no crack or breakage near the opening (11) on the upper surface.

  Further, since there is only one adsorbing tool (2) above, it is only necessary to prepare one exhaust device, and it is not necessary to increase the capacity, so that the entire size can be reduced even if the exhaust device is included. .

  Next, the upper plate (4) is raised as shown in FIG. Since the upper surface of the bag-shaped food (1) is adsorbed by the adsorbing tool (2) and the lower surface is grasped by the grasping tool (3), the upper surface of the bag-shaped food (1) is adsorbed as the upper plate (4) rises. It is lifted while being held in (2), and the opening (11) is largely open. And in this state, foodstuffs with sushi rice are packed in the bag-like food (1) by the food insertion device (8) provided on the opening (11) side. Then, after the filling of the food into the bag-shaped food (1) is completed, the food insertion device (8) is returned to the initial position, and then the valve is switched so that air is discharged from the adsorber (2). The lower surface of the bag-like food (1) is released by controlling the upper surface of the bag-like food (1) downward from the adsorbing tool (2) and separating the opposing cutting edge (32) of the gripping tool (3).

  Further, when the adsorbing tool (2) holds and lifts the upper surface of the bag-like food (1), the gripping tool (3) only grabs the lower surface of the bag-like food (1) at that position and does not move downward. In addition, since an excessive force is not applied to the lower surface of the bag-shaped food (1), the lower surface of the bag-shaped food (1) is not cracked or damaged.

  This bag-shaped food opening device can be used in an inari sushi production line as shown in FIG. In this production line, the bag-like food (1) is sequentially conveyed by the lower plate (5), and sushi rice can be continuously packed into the plurality of bag-like foods (1).
