Description

Technical Field

[0001] The present invention relates to a material box for packaging and delivering a set of food / ingredients, in particular to a material box for packaging pre-prepared dishes or take-out dishes, a material box for packaging and delivering cooking materials and for manual feeding, or a material box for packaging and delivering cooking materials and for an automatic film-tearing and feeding device in a cooking device; the present invention also relates to a feeding device and a feeding method capable of automatically tearing the film of the material box. Background Art

[0002] With the rise of take-out, pre-prepared meals and automatic cooking equipment, there is an increasing demand for a set of material boxes that can package two or more foods / ingredients, and put different materials into separate material compartments and seal them with film. However, this type of box usually has a common problem: it is troublesome to find a position where the sealing film can be separated from the box body and to separate the two. For example, the sealing film of most boxes is the same shape and size as the opening surface of the box. When opening the film, it is often difficult to find a separable position conveniently and quickly, and because the edges of the box body and the film overlap and are tightly bonded together, it is not easy to separate them quickly. Some boxes are equipped with a protruding film head, but the soft film head is easy to curl, bend and deform, making it difficult to tear the film and open the box. If the cooking equipment automatically tears the film, the above situation will seriously affect the automatic, accurate and stable connection between the automatic film tearing device and the film and the tearing of the film to open the box.

[0003] In recent years, with the cost restrictions of personnel and venues, the need for standardization of chain stores, and the emergence of new catering models, automatic cooking equipment such as cooking machines have been widely used in the catering industry, and small cooking machines for families are also entering the kitchen. The feeding device is one of the core modules of automatic cooking equipment. The cooking machines currently on sale have feeding devices that can be manually prompted to feed or automatically fed; most automatic feeding devices use multiple material boxes to hold the raw materials separately, and then use suction cups to suck the material boxes and feed them into the pot. There are also disposable material boxes, such as multi-grid material boxes, where the raw materials are placed in each grid and then sealed with hot pressing film. Before putting the material into the feeding mechanism, the sealing film is torn open manually, and the feeding mechanism is placed with the opening facing up. When feeding, the material box is turned over and the material is fed with the opening facing down, or the protruding part of the sealing film is connected to the feeding mechanism manually, and then the feeding mechanism feeds the material by rolling or tearing the film.

[0004] Some feeding devices using sealed film boxes, due to the unresolved technical problems of automatic film clamping and tearing, use manual tearing of the film before loading, put the feeding mechanism into the box with the opening facing upwards, and flip the box when feeding. However, this brings a problem, because the materials are both solid and liquid, and when cooking, solid materials such as main and auxiliary materials are usually put in first, and liquid materials such as seasonings and water starch are put in later. For solid materials, baffles can be used to block the materials that are not put in temporarily when the box is flipped, but it is difficult to prevent the liquid materials in other material grids from flowing out together. Therefore, it is difficult to load liquid materials into the box of this feeding device, and a liquid material feeding device needs to be set up separately. The equipment is complex, costly and prone to failure.

[0005] Chinese patent 200610033780.5 discloses an automatic feeding mechanism, in which a packaging film head separated from the material box body and having an appropriate length is arranged on the material box packaging film, and after two film clamping bodies clamp the packaging film head, the packaging film is rolled / pulled for feeding. One of the keys to the success of this device and method to achieve automatic feeding is that the two film clamping bodies as the connecting mechanism can automatically and correctly connect with the packaging film head, be stable and reliable, and be able to withstand a certain degree of force. However, since the packaging film head is thin and soft, and may be deformed during packaging, storage and transportation, such as bending, curling, etc., it is not easy to connect and fix with the connecting mechanism correctly and reliably, especially not easy to connect and fix automatically. For example, it is common that the packaging film head is too soft and cannot overcome resistance to be inserted, and part or all of it cannot be automatically and reliably placed in the correct position for connection with the connecting mechanism, or it cannot be clamped, only partially clamped, or not clamped tightly due to curling, bending and deformation of the protruding part. Because it is difficult to correctly and reliably realize the automatic connection and fixation between the connection mechanism and the sealing film protrusion, it is often necessary to flatten, press, give hardness, overcome resistance, insert, and align the thin and soft sealing film that may have been bent, curled, and deformed manually or with the assistance of manual labor. In order to solve this problem, the patent designs a film pressing device for sending the sealing film protrusion into the opening between the two film clamping bodies. However, when the head of the packaging film is deformed during storage and transportation, such as bending or curling, it is not easy for the film pressing device to send it into the correct position of the opening between the two film clamping bodies and clamp it all. The head of the packaging film itself is relatively soft and easy to roll. This film pressing device also requires the packaging film head to be relatively long, which is more likely to bend, curl, and deform, increasing the possibility of film clamping failure. This film pressing device requires the addition of a motor and a mechanism, which is complex and unreliable.

[0006] In order to solve the problem of effective and reliable connection, Chinese patent ZL 03137940 proposes to set slots, tooth-like protrusions, protrusions, holes, grooves, thickened and hardened, sticky or rough parts, hooks, etc. on the sealing film, but no feasible technical solution is proposed. Whether such settings can solve the problem of effective and reliable connection and fixation is not only questionable, but also the packaging film of the factory sealing equipment is usually rolled, and it is quite difficult to make these settings when producing rolled sealing films, and it will increase the cost of the sealing film itself, and also bring problems and difficulties to the process implementation of the actual sealing film in the side dish factory.

[0007] Therefore, it is necessary to provide a packaged material box that has good sealing performance and is easy to tear off the film and open the box, especially a packaged material box that is easy to automatically connect and tear off the film of a feeding device of a cooking device, and an automatic film tearing and feeding device for the material box. Summary of the invention

[0008] One of the purposes of the present invention is to provide a material box that can hold pre-prepared dishes or other food / cooking ingredients, which is easy to tear off the film and open the box, in order to solve the problems existing in the prior art of complete material boxes and material box feeding.

[0009] Another object of the present invention is to provide a set of cooking material boxes, a feeding device and a method for automatically feeding cooking materials, which enable an automatic feeding device to effectively and stably connect and fix the material box sealing film, thereby automatically opening the material box sealing film and facilitating automatic feeding in time and batches.

[0010] On the one hand, in order to achieve the above-mentioned invention object, the present invention provides a material box for packaging a set of food / ingredients, the material box comprising a box body and a sealing film; wherein the box body comprises two or more material compartments separated by material compartment partition walls for placing materials, and each material compartment is provided with an opening in the same direction; a sealing edge for sealing with the sealing film is provided at the periphery of the top of the box body with the opening, and a sealing grid for sealing with the sealing film is also provided at the top of the partition wall of the material compartment; the sealing film is tightly sealed with the sealing edge and the sealing grid to form a material box in which each material compartment is independent of each other and the opening is closed;

[0011] The material box is further provided with one or more box body protrusions at the front of the box body, the box body protrusions are connected to the edge seal at the front of the box body as a whole, and a breakable structure is provided at the connection between the box body protrusions and the edge seal at the front of the box body for easy breaking;

[0012] The sealing film is also provided with a sealing film protrusion at the front thereof, which forms a tight seal with the protrusion of the box body, and the relatively soft sealing film protrusion and the relatively rigid protrusion of the box body together form a straight and relatively rigid rigid body;

[0013] When subjected to external force, the breakable structure breaks, causing the connection between the box body protrusion and the front edge sealing of the box body to be disconnected, resulting in the box body protrusion being separated from the front edge sealing of the box body, but still connected to the sealing film protrusion as a whole.

[0014] The material box of the present invention can be a material box for packaging pre-prepared dishes / take-out, a material box for packaging and placing cooking materials and for manual feeding, or a material box for packaging and placing cooking materials and for an automatic film tearing and feeding device in a cooking device, wherein the rigid body of the material box facilitates manual film tearing or placement in an automatic film tearing and feeding device.

[0015] In the present invention, a set of food / ingredients may refer to a variety of different foods / ingredients that are matched together, or may refer to a variety of different cooking materials for cooking a certain dish.

[0016] In the material box of the present invention, a film-tearing force structure for easy grasping by hand or a film-tearing connection structure for easy connection with an automatic film-tearing and feeding device is further provided on the protruding portion of the box body.

[0017] When tearing the film manually, the tearing force structure should be a structure that is convenient for the human hand to exert force and will not cause discomfort to the human hand as much as possible, for example, it should be relatively wide and thick at the contact point of the human hand, or even provided with elastic materials. The structure itself can be varied, for example, a pull hole can be provided on the protruding part of the box body to facilitate the insertion of one or more fingers. When tearing the film mechanically, the tearing connection structure can be more varied, as long as it is convenient for the fixed connection between the rigid body and the connection structure in the automatic tearing film feeding device.

[0018] In the material box of the present invention, the box body includes a plurality of material grids, and materials are placed in different material grids respectively. After the box body is filled with materials, the box body is covered with a sealing film as a whole by heat sealing or bonding, and the openings of the material grids of the box body are sealed to form a closed feeding box.

[0019] In the material box of the present invention, not only the sealing film head is provided with a protrusion, but the head of the box body is also provided with a protrusion. When the material box is covered and sealed with a sealing film by heat sealing or bonding, the sealing film protrusion is attached to the protrusion of the box body and connected therewith as a whole. The thin and soft sealing film protrusion is not easy to bend, curl or deform because it is connected as a whole with the harder protrusion of the box body. It is easy to maintain a relatively straight state and has a certain hardness, which is particularly convenient for overcoming the resistance of the automatic film tearing and feeding device.

[0020] In the material box of the present invention, a breakable structure which is easy to break is provided at the connection between the protrusion of the box body and the front edge seal of the box body. When subjected to external force, the connection between the protrusion of the box body and the front edge seal of the box body is disconnected due to the weak strength of the breakable structure, and the protrusion of the box body and the sealing film protrusion which are connected as one can be separated from the material grid of the box body together.

[0021] The shape of the protrusion of the box body matches the connecting mechanism of the feeding device, and is a shape that is easy to connect and fix. Usually, its front end is tongue-shaped, rectangular, trapezoidal, or has a pointed shape, etc., and can be the same width or different widths as the front edge seal of the material box body. The front end of the sealing film protrusion is preferably consistent with or similar to the shape of the front end of the protrusion of the box body.

[0022] In the material box of the present invention, the fragile structure refers to a portion with weaker strength formed at the connection between the protrusion of the box body and the front edge seal of the box body. For example, the fragile structure can be a groove, a depression, a hole, a locally thinned or locally narrowed structure, or a combination of the above structures. The protrusion of the box body can also be thinner, narrower, smaller, etc. than the front edge seal of the box body.

[0023] In the material box of the present invention, the overall shape of the breakable structure is a straight line, a broken line, an arc, a U-shape or other shapes.

[0024] In the material box of the present invention, the top of the box body refers to the open part (or opening) of the material grid. The periphery of the top of the box body is provided with an edge seal so as to be sealed with the sealing film. As a specific embodiment, the edge seal itself is the cross-section of the vertical walls around the box body, especially when the vertical walls around the box body are thicker. However, for disposable material boxes, the vertical walls around the box body are usually not too thick. At this time, it is very necessary to connect the vertical walls around with edge seals (generally formed in one time) to ensure the quality of the seal. The width of the edge seal can be 1-50mm, preferably 3-30mm, and the width of the edge seals around can be different. The width of the same edge seal can also vary with factors such as the change in the shape of the material grid. Some regular or irregular shapes can also be set on the edge seal, such as wavy or serrated edges, holes of various shapes and numbers (which can be used to identify the characteristics of dishes and the characteristics of materials in the material grid, etc.).

[0025] In the material box of the present invention, the top plane shape of the box body excluding the box body protrusion is preferably rectangular.

[0026] In the present invention, the terms such as front and rear related to directions refer to the forward direction of the material box in the feeding device as the front.

[0027] As a specific implementation, the rear end of the protruding portion of the box body is in a straight line shape, and is connected to the front end of the front edge seal of the box body by a straight line breakable structure.

[0028] As another preferred embodiment, the rear end of the protruding part of the box body is partially or entirely convex backward, and correspondingly, the front end of the front edge seal of the box body is concave backward, and the breakable structure connecting the two is a broken line, arc, U-shaped or other shapes. Compared with a straight line structure, this type of breakable structure can withstand a relatively large bending force and is less likely to be accidentally broken during packaging, storage and transportation.

[0029] In order to further enhance the ability to withstand relatively large bending external forces and avoid accidental breakage during packaging, storage and transportation, the fragile structure may also be provided with a protective structure, such as reinforcing ribs, reinforcing plates, protective boxes, covers, etc. For example, such a protective structure is provided with mechanisms such as buckles, which can be opened or removed manually before feeding, or opened or removed by a corresponding mechanism provided by the feeding device when the material box is placed in the feeding device.

[0030] In the material box of the present invention, the box body protrusion may be one or more than one. For example, the box body protrusion may be two or more smaller protrusions provided on the head of the box body, and the sealing film protrusion may be larger than these protrusions and remain straight under the support of these protrusions. These small protrusions are also easy to break.

[0031] In the material box of the present invention, the breakable structure can be integrally formed by injection molding, molding, hole punching, etc. during the manufacture of the material box body, which is convenient for large-scale manufacturing and processing of the material box body.

[0032] In the material box of the present invention, in order to facilitate the tight sealing of the sealing film, preferably, the upper surface of the protruding portion of the box body and the upper surface of the sealing edge and the surface of the sealing grid are located in the same plane.

[0033] In the material box of the present invention, in order to facilitate the connection and fixation between the material box and the automatic film tearing and feeding device, preferably, the box body protrusion and the film sealing protrusion can be further provided with a film tearing connection structure connected to the film tearing and feeding device. For example, holes, convexoconcave, rough surface, etc. This film tearing connection structure can cooperate with the connection mechanism in the automatic film opening device to ensure the connection and fixation of the box body protrusion.

[0034] In the material box of the present invention, in order to increase the connection strength between the sealing film protrusion and the box body protrusion, preferably, the sealing film protrusion not only covers the upper surface of the box body protrusion, but also covers at least a part of the lower surface of the box body protrusion.

[0035] On the other hand, in order to achieve the purpose of the present invention, the present invention provides an automatic film tearing and feeding device, which includes a material box holder for placing and supporting the above-mentioned material box and an automatic film opening device; wherein the automatic film opening device includes a connecting mechanism that can automatically connect and fix with the sealing film protrusion and the box body protrusion of the material box, a breaking device that can automatically break the box body protrusion along the breakable structure after the connecting mechanism is connected and fixed with the sealing film protrusion and the box body protrusion, and a material box limiting mechanism, which fixes the material box at a certain position on the material box holder, or limits the movement of the material box within a certain range, or allows the material box to move in a certain direction within a certain range.

[0036] In the present invention, the automatic film opening device is a device that can separate the sealing film from the box body by rolling, pushing, pulling, etc., so that the material in the box body falls into the pot.

[0037] In the automatic film-tearing and feeding device of the present invention, the connecting mechanism is a mechanism that can automatically connect with the film-sealing protrusion and the box body protrusion without manual assistance; after the film-sealing protrusion and the box body protrusion are placed together in the connecting mechanism in a state of being connected as one, the connecting mechanism automatically connects and fixes with the film-sealing protrusion and the box body protrusion connected as one. Insertion here means inserting, pushing, putting in or other ways so that the film-sealing protrusion and the box body protrusion connected as one reach a position where they can be correctly connected and fixed with the connecting device.

[0038] In the automatic film tearing and feeding device of the present invention, the connecting mechanism is an automatic clamping, pressing, hanging or perforating mechanism. When the sealing film protrusion and the box body protrusion are placed together in a position connected to the connecting mechanism, the connecting mechanism automatically clamps, presses, hangs or penetrates into the hole on the box body protrusion to fix it and drive it to move.

[0039] Since the thin and soft sealing film protrusion is attached to the harder protrusion of the box body and connected therewith, it is easier to enter and reach the correct position, and can be automatically and correctly connected and fixed by the connecting mechanism. During the insertion process, it can also overcome possible resistance, such as the resistance of the elastic pressing sheet encountered when inserting into the slot, and be correctly and firmly fixed together. There is no need for manual assistance to flatten and press the thin and soft sealing film that may have been bent, curled and deformed during the insertion and connection and fixing process in order to give it hardness and overcome resistance for insertion.

[0040] In the automatic film tearing and feeding device of the present invention, the connecting mechanism can be an automatically openable and closable structure. When the material box is placed in the automatic film tearing and feeding device, the connecting mechanism can automatically open the opening, and the film sealing protrusion and the box body protrusion connected as one can be pushed, inserted or placed in the opening, or the connecting mechanism moves so that the film sealing protrusion and the box body protrusion enter the opening, and the connecting mechanism automatically closes the opening and clamps the film sealing protrusion and the box body protrusion at the same time.

[0041] The above-mentioned automatic opening and closing structure is a reel clamping mechanism, including reel opening and clamping, reel winding mechanism, the reel opening is composed of active clamping body and fixed clamping body, the active clamping body and fixed clamping body are dynamically connected and can rotate relative to each other. The reel opening can be actively opened and closed by applying power, such as applying external force to the active clamping body to open it, or it can be passively opened, such as when the reel is moving, it encounters resistance from an obstacle and opens the active clamping body.

[0042] The active clamping body and the fixed clamping body can be connected by a hinge and can rotate relative to each other. The active clamping body and the fixed clamping body can be pre-tightened and closed by a spring so that they can open when subjected to external force and resume closing when the external force is removed.

[0043] In addition to being connected to form an integral structure by rotation through a hinge, the active clamping membrane body and the fixed clamping membrane body can also be an integral structure that can be translated and pressed against each other. When the mouth needs to be opened, a force is applied, such as installing an electromagnet core on the fixed clamping membrane body. When power is turned on, the active clamping membrane body is pushed open to form an opening. When power is turned off, the electromagnet core pulls the main clamping membrane body to reset through a spring to form a closure.

[0044] After the reel clamping mechanism forms an opening by rotating or moving, the sealing film protrusion and the box body protrusion can be placed into the opening manually or by an automatic box feeding mechanism, and the reel opening can be closed to complete the clamping when the winding mechanism starts to move.

[0045] The above-mentioned film reel clamping mechanism can also be a reel without an opening structure, such as having several protrusions on the reel surface, and corresponding holes on the corresponding protrusions of the film head of the material box. When the reel rotates, the protrusions enter the holes of the protrusions of the film head, and continued rotation drives the material box to move and tear the film.

[0046] The above-mentioned opening and clamping of the reel can also increase the clamping force of the membrane head by adding protrusions on the active membrane clamping body or the passive membrane clamping body, and opening holes in the corresponding protruding parts of the membrane head. In this way, after the protruding part of the membrane head enters the opening part and is clamped, the protrusion enters the hole of the protruding part of the membrane head. When the reel starts to open and close, the protruding part of the membrane head will not fall off from the opening part.

[0047] The above-mentioned automatic opening and closing structure can be equipped with a device or arrangement that can enhance the clamping force, such as adding a protrusion to the active film clamping body of the reel clamping mechanism and adding a corresponding recess to the fixed film clamping body to enhance the bite force of the clamping mechanism. The corresponding film sealing protrusion and box body protrusion can also be equipped with a connecting structure, such as a hole, so that after the film sealing protrusion and the box body protrusion enter the opening and are clamped, the protrusion enters the hole, and the film sealing protrusion and the box body protrusion can be fixed more stably after the reel is opened and closed.

[0048] In the automatic film-tearing and feeding device of the present invention, the connecting mechanism can also be a slot, in which there is an elastic pressing piece or other device capable of fixing the protrusion. Because the protrusion of the box body and the protrusion of the sealing film have a certain hardness and straightness, they can overcome the resistance of the elastic pressing piece and the like, be inserted into the slot together, and be stuck, pressed or otherwise fixed by the elastic piece or other device.

[0049] In the automatic film tearing and feeding device of the present invention, the connecting mechanism can also be a perforated structure. For example, a protrusion is provided on the connecting mechanism, and the film sealing protrusion of the material box and the protrusion of the box body have corresponding holes. When the connecting mechanism moves, the protrusion enters the holes of the film sealing protrusion and the protrusion of the box body and is connected and fixed thereto.

[0050] In the automatic film tearing and feeding device of the present invention, the connecting mechanism, as a part of the automatic film opening device, can be split. For example, the connecting mechanism fixed near the feeding port is connected and fixed to the film sealing protrusion at the front end of the material box and the protrusion of the box body. Other components of the automatic film opening device push the rear end of the material box to move forward, and relative movement and separation are generated between the film sealing and the box body.

[0051] In the automatic film tearing and feeding device of the present invention, the connecting mechanism is preferably integrated with the automatic film opening device. For example, the automatic opening and closing structure may also include a rotating mechanism or a film pulling mechanism. After clamping the film, the mechanism rotates the film or pulls the sealing film to separate the sealing film from the box body.

[0052] In the automatic film-tearing and feeding device of the present invention, the slot and the perforation structure may also include a motion mechanism, which is connected and fixed to the sealing film to separate the sealing film from the box body by rolling, pushing, pulling, etc.

[0053] In the automatic film-tearing and feeding device of the present invention, the breaking device of the protrusion of the box body is a moving mechanism, which drives the connecting mechanism and / or the material box to rotate or move in a direction at a certain angle to the horizontal plane of the box body opening after the connecting mechanism is connected and fixed with the film sealing protrusion and the box body protrusion connected as one, applies external force to the box body or the protrusion of the box body, breaks the connection between the protrusion of the box body and the edge sealing of the box body, and separates it from the box body.

[0054] In the automatic film tearing and feeding device of the present invention, the breaking device is preferably integrated with the automatic film opening device, such as the above-mentioned mechanism that can separate the sealing film from the box body by rolling, pushing, pulling, etc., after its connecting mechanism clamps the sealing film protrusion and the box body protrusion, the automatic film opening device rotates or moves in a direction at a certain angle to the horizontal plane of the box body opening to break the box body protrusion.

[0055] In the automatic film-tearing feeding device of the present invention, the material box is preferably automatically placed into the feeding device by a robot or other automatic material box loading mechanism.

[0056] In the automatic film tearing feeding device of the present invention, the material box limiting mechanism can be a guide bracket. The material box is placed on the guide bracket of the limiting mechanism, and the guide bracket is provided with a guide limiting groove. The two sides of the material box can slide horizontally and linearly along the groove. The two sides of the material box are limited in the vertical direction by the pressing edge set on the bracket to prevent it from moving up and down.

[0057] In the automatic film tearing and feeding device of the present invention, the automatic film opening device can be an opening and clamping reel mechanism. After opening and clamping the sealing film protrusion and the box body protrusion, the reel rotates to break the box body protrusion, and then the reel rotates to roll the film, or pulls the sealing film to the rear end of the material box, opens the material grid, and moves the material box to the front end to the feeding port for feeding. The material box can also be pushed by other mechanisms to separate the sealing film from the box body and feed the material.

[0058] In the automatic film tearing and feeding device of the present invention, the automatic film opening device can also be a connecting film pulling device. After the connecting mechanism is connected to the sealing film protrusion and the box body protrusion, the box body protrusion is broken and then pulled back while retreating, and the material box moves forward along the guide limit groove, or the material box is fixed and the sealing film protrusion is pulled to retreat and tear at the same time.

[0059] In the automatic film tearing and feeding device of the present invention, the automatic film tearing and feeding device also includes one or more vibration generators, which generate vibrations acting on the material box and drive the material in the material box to vibrate; the control system controls the position, timing, intensity, mode and duration of the vibration generated by the vibration generator according to the cooking feeding program and the material characteristics; the position where the vibration generator vibrates the material box is the sealing film of the material grid opening and / or the box body of the material box, preferably the sealing film.

[0060] On the other hand, in order to achieve the purpose of the present invention, the present invention also provides a method for automatically adding cooking materials, the method comprising the following steps:

[0061] A. Place the above-mentioned material box into the above-mentioned automatic film tearing and feeding device, and place the rigid body into the correct position of the connecting mechanism of the automatic film tearing and feeding device;

[0062] B. Connect and fix the connecting mechanism to the rigid body;

[0063] C. Make the breaking device of the automatic film tearing and feeding device drive the connecting mechanism or the material box to rotate, or move in a direction at a certain angle to the horizontal plane of the material grid opening, apply external force to the box body or the protrusion of the box body, break the protrusion of the box body, and separate it from the box body;

[0064] D. Make the automatic film-opening device of the automatic film-tearing and feeding device separate the sealing film from the box body by rolling, pushing, pulling, etc., so that the material in the box body falls into the pot.

[0065] The above-mentioned method for automatically feeding cooking materials also includes the step of automatically opening the film device or moving the material box so that the material grid containing the material to be fed is opened above the material drop opening, and the material falls into the pot through the material drop opening.

[0066] The above-mentioned method for automatically feeding cooking materials also includes the step of the automatic film opening device moving in the reverse direction after the material feeding is completed to complete the film removal.

[0067] The above-mentioned method for automatically adding cooking materials also includes a step in which the automatic connecting mechanism disconnects the sealing film protrusion and the box body protrusion.

[0068] The above-mentioned method for automatically feeding cooking materials also includes the vibration generator vibrating the sealing film of the material grid opening of the material box and / or the box body of the material box, preferably vibrating the sealing film.

[0069] In the material box of the present invention, the relatively soft sealing film protrusion and the relatively rigid box body protrusion together form a flat, relatively rigid body that is easy to place into the film tearing and feeding device, and the connection between the box body protrusion and the front edge seal of the box body is provided with an easy-to-break structure that is easy to break. Therefore, it is particularly convenient to open the sealing film of the material box and feed in batches and at different times, which is not only convenient for automatic cooking, but also convenient for take-out and pre-prepared dishes.

[0123] like Figure 1 As shown, the automatic connection, film opening and feeding device is composed of a guide bracket 1, a film sealing material box 2, a film opening mechanism 3, a top block 4, a material drop port 6, etc. The material dropped from the material box falls from the material drop port 6 into the pot 5.

[0124] like Figure 2 and Figure 3 As shown, the guide bracket 1 is located above the pot 5, and the guide bracket 1 is provided with a guide groove 7, the width of which is the same as that of the film sealing material box 2, and the film sealing material box 2 can be placed in the guide groove 7 and slide along the guide groove 7. The guide bracket 1 is provided with a section of pressing edge 8 on both sides of the guide groove 7 at the position of the blanking port 6, and the pressing edge 8 and the bottom surface of the guide groove 7 form a [-shaped limiting groove 9. When the film sealing material box 2 slides along the guide groove 7 to the blanking port 6, it will enter the [-shaped limiting groove 9. In this area of ​​the blanking port 6, the [-shaped limiting groove 9 can limit the upward and downward movement of the film sealing material box 2.

[0125] The film sealing material box 2 is composed of a box body 10, a box body protrusion 11, and a film 12. Fig.10 The box body 10 without the sealing film 12 and the box body protrusion 11 are integrally connected and formed by injection molding or vacuum molding. Figure 4 , Figure 6 or Figure 8 shown. Figure 5 This is an enlarged schematic diagram of the integral connection. The box body 10 and the box body protrusion 11 are connected through an easy-to-break groove 36. A number of reinforcing ribs 35 are provided on the easy-to-break groove 36. The thickness of the easy-to-break groove 36 is much smaller than the thickness of the box body 10. The box body protrusion 11 is easily broken by external force and separated from the box body 10. In addition to the above straight line form, the easy-to-break groove 36 can also be as follows Figures 6 to 9 The U-shaped, arc-shaped and other easily breakable groove structures are shown. When the material grid of the box body 10 is filled with raw materials, the film 12 is hot-melted to cover the box body 10 and the box body protrusion 11, so that the material does not come out of the box body 10. Fig.10 Under the action of external force, although the box body 10 is separated from the box body protrusion 11, the film 12 is hot-melted on the box body 10 and the box body protrusion 11, and the film sealing material box 2 is still a whole.

[0126] like Fig.11 , Fig.12 As shown, the reel clamping mechanism 3 is composed of a reel 13, a fixed clamping film body 14, an active clamping film body 15, a torsion spring 16, a reel rotation motor 17, a reel swing rod swing drive motor 18, a reel swing rod 20, etc. The fixed clamping film body 14 is a semi-axial structure, which is coaxially fixedly connected to the reel 13. The active clamping film body 15 is also a semi-axial structure with the same diameter as the fixed clamping film body 14. The active clamping film body 15 and the fixed clamping film body 14 are connected by a hinge 22, and the torsion spring 16 makes the active clamping film body 15 closed with the fixed clamping film body 14 in static state. At this time, the active clamping film body 15, the fixed clamping film body 14, and the reel 13 are coaxial. When the active clamping film body is subjected to external force, it will rotate around the hinge 21 and separate from the fixed clamping film body 14 to form an opening.

[0127] The two ends of the reel 13 are axially mounted on the two end holes of the reel swing rod 20, and the reel rotation motor 17 is fixedly mounted on the reel swing rod 20 and coaxially connected to the reel 13. The reel swing rod 20 can be driven by the reel swing rod driving motor 18 to rotate around the swing rod axis 19. The two ends of the fixed film clamping body 14 are provided with avoidance openings 21. When the reel swing rod 20 is driven by the reel swing rod driving motor 18 to swing upward, the fixed film clamping body 14 avoids the top block 4, and the active film clamping body 15 is subjected to the resistance of the top block 4 and gradually separates from the fixed film clamping body 14, forming a film clamping opening 23.

[0128] When film clamping is required, the protrusion 11 of the box body is pushed into the [-shaped limit groove 9 along the guide groove 7, and then enters the film clamping opening 23. Then the reel rocker driving motor 18 drives the reel rocker to swing downward in the reverse direction, and the active film clamping body 15 gradually leaves the top block 4. Due to the action of the torsion spring 16, the active film clamping body 15 is reset, and the film clamping opening 23 is closed to clamp the protrusion 11 of the box body. After the fixed film clamping body 14 and the active film clamping body 15 completely clamp the film head protrusion 11, the reel swing rod driving motor 18 stops rotating, and the reel swing rod 20 is stationary. At this time, the uppermost part of the fixed film clamping body is basically flush with the film, and the reel rotation motor 17 starts to rotate, driving the reel 13 to rotate, and the fixed film clamping body 14 and the active film clamping body 15 rotate with the reel 13. The protruding part 11 of the box body is clamped and driven by the fixed film clamping body 14 and the active film clamping body 15, and is subjected to the force of separation from the box body 10, thereby separating from the box body 10. Because the box body 10 is limited in the [-shaped limiting groove 9, it can only move forward, thereby gradually separating the film 12 from the box body 10, and the material in the box body 10 falls into the pot 5 under the action of gravity, thereby completing the feeding of the material. As shown in the figure, the box body 10 can be divided into multiple grids, and the amount of travel of each grid to tear the film can be determined by a position sensor.

[0129] In order to clamp the protruding portion 11 of the box body more reliably and prevent the film from being pulled out from the film clamping opening 23 when tearing the film, a row of small holes 24 can be provided on the protruding portion 11 of the box body, such as Figure 4 As shown, a row of pins 25 are provided at corresponding positions on the fixed clamping membrane body 14 or the active clamping membrane body, and the axial diameter of the pins 25 is smaller than the diameter of the small hole 24. When the fixed clamping membrane body 14 and the active clamping membrane body 15 are closed, the pins 25 pass through the inside of the small hole 24, thereby firmly clamping the protrusion 11 of the box body so that it is not pulled out of the clamping membrane opening 23 when subjected to tension.

[0130] The box body 10 and the box body protrusion 11 may also be Fig.13 In the structure shown, the box body 10 protrudes two small pieces 26, and when the film is sealed, the film 12 is also sealed together with the small pieces 26, so that the two small pieces 26 can ensure that the film 12 enters the opening of the film clamp in a horizontal state. Correspondingly, a groove slightly larger than the size of the small piece 26 is opened at the position corresponding to the small piece 26 of the fixed film clamp body 14, so that when the film is clamped, it is ensured that only the film is clamped, and the small piece 26 can be separated from the opening of the film clamp body.

[0131] In addition to the aforementioned easy-to-break structure between the box body 10 and the box body protrusion 11, external force can also be applied to cut, fuse, shear, etc. to ensure that the box body protrusion 11 and the box body 10 are smoothly separated.

[0132] When the film is torn off, the reel motor 17 reverses to complete the film unwinding. After the film unwinding is completed, the reel swing arm motor 18 reverses and moves downward, the active film clamping body 15 and the fixed film clamping body 14 are separated, the film clamping opening 23 is opened, and the film 12 can be taken away by removing the material box.

[0133] The film clamping and tearing structure adopts the reel 13 to drive the film clamping body to rotate to complete film clamping, tearing and stripping. Alternatively, the active film clamping body 15 and the fixed film clamping body 14 can automatically clamp the protruding part 11 of the box body, and then the box body 10 can actively move forward in a straight line. Since the protruding part 11 of the box body does not move after being clamped, the box body 10 is pulled by the protruding part 11 of the box body when moving, thereby completing the separation of the protruding part 11 of the box body 10. When moving forward, the film 12 is gradually separated from the box body 10, so that the material in the material box will fall into the pot 5. Conversely, the material box 10 can also be stationary, and after the active film clamping body 15 and the fixed film clamping body 14 clamp the protruding part 11 of the box body, the entire film clamping device can move backward in a straight line to drive the protruding part 11 of the box body 10 to separate and let the material fall.

[0134] The above-mentioned method of fixing the film is not limited to the sandwich film, and can also be as follows Fig.14 Fixed membrane head:

[0135] The material box support 34 is provided with a [-shaped guide groove 33, and the material box 30 can slide linearly along the [-shaped guide groove 33. The material box 30 is sealed with a film 28, and a small hole 29 is opened on the film 28. A reel 32 is provided below the [-shaped guide groove 33, and a positioning pin 31 is provided on the reel 32. The small hole 29 on the film 28 can be hung on the positioning pin 31 first, or the reel 32 can rotate, and then the positioning pin slowly enters the small hole 29 on the film 28 as the reel 32 rotates. In this case, the small hole 29 can be set as a waist-shaped hole to facilitate the positioning pin 31 to enter, see Fig.15 As shown. The reel 32 is connected to the film winding motor 27. When the film winding motor 27 rotates, the reel 32 can be driven to index the film 28 to move. Due to the action of the [-shaped guide groove 33, the film 28 is wound around the circumference of the reel 32, and the film 28 is separated from the material box 30 while being rolled. The material box 30 moves forward along the [-shaped guide groove 33. Because the film 28 is separated from the material box 30, the material falls from the material box. This method of directly opening a hole in the film has a relatively weak hole strength, so the film head will be left slightly longer, and the length is enough to wrap around the reel once before tearing the film, and then the hole will be better stressed after the film is torn.

[0136] This method is also applicable to the aforementioned easy-to-tear small hole on the protrusion 11 of the box body or the long waist-shaped hole material box structure. The small hole on the protrusion 11 of the box body is hung into the positioning pin 31 of the reel 32 in advance, or the reel 32 is rotated to make the positioning pin 31 enter the long waist-shaped hole. In this way, the rotation of the reel 32 will pull off the protrusion 11 of the box body, and the film will be rolled into the reel 32 along with the protrusion 11 of the box body and separated from the material box at the same time, and the material will fall down.

[0137] After the film tearing and feeding are completed, the film winding motor 27 is reversed, the film 28 is separated from the winding shaft 32, and the material box 30 is removed to take away the film 28.
