Description

Computer numerical control flow blocking system according to container characteristics and food ingredients characteristics

The present invention relates to a food processing system, and in particular to a computer numerically controlled flow blocking system that depends on the characteristics of the container and the characteristics of the food ingredients.

At present, the surface decoration of cakes, biscuits and other food products usually involves putting paste-like ingredients such as cream, frosting, chocolate or jam into piping bags, and manually extruding the paste-like ingredients in the piping bag through a conical nozzle. To decorate the surface of food. The food surface is decorated with various patterns, shapes, words and other patterns to increase customers' desire to buy. Although there are computer numerical control (CNC) food processing machines at present, since the extrusion head is often replaced during the extrusion process, the existing extrusion head placement frame needs to be equipped with fixing elements to fix or loosen the extrusion head. The extrusion head can only be installed or removed before the extrusion head can be installed or removed, so the action of replacing the extrusion head will take a lot of time, and the time for fixing or loosening the extrusion head of the fixing element must be coordinated accurately, otherwise the extrusion head will easily fall to where the extrusion head is placed. The outside of the rack or it is skewed, causing the process to have to be interrupted. Traditionally, when squeezing food, after the food fluid is squeezed, even if the squeezing action is stopped, the liquid will continue to flow out due to residual pressure, making it difficult to control the flow rate required for extrusion and the squeezing nozzle (i.e. the extrusion head) Residues are left outside, which affects the shape of the extruded flowers and makes cleaning difficult. However, the current squeezing device not only cannot adjust the required temperature according to the characteristics of the food, but also often causes the squeezing nozzle to become clogged. Too much stuffing or extrusion is difficult to control, and ingredients can easily remain in the squeezing nozzle, resulting in defects in the extruded products, so labor is required to clean them. Moreover, there is currently no design on the market that can automatically mix and color food materials. Therefore, users need to manually mix and color. However, each color mixing requires the use of a certain amount of food materials, and the user cannot adjust the color at any time. Mixing and coloring can be done at any time.

In order to facilitate understanding of the technical features, content and advantages of this invention and the effects it can achieve, this invention is described in detail below with diagrams and in the form of expressions of embodiments. The purpose of the diagrams used is only They are for illustration and auxiliary instructions, and may not represent the true proportions and precise configurations of the creation after its implementation. Therefore, the proportions and configurations of the attached drawings should not be interpreted to limit the scope of rights in the actual implementation of this creation. In addition, to facilitate understanding, the same elements in the following embodiments are labeled with the same symbols for explanation.

Please refer to Figures 1 to 5 and 10. In the first embodiment, the computer numerically controlled flow blocking system 100 of the present invention is suitable for installation on a food processor 200 and is used to detachably connect the extrusion head 60, wherein The extrusion head 60 is stored, for example, in an extrusion head storage rack 210 . The food processor 200 is, for example, a CNC food processor capable of operating multiple axes. The computer numerically controlled flow blocking system 100 of this invention includes a mixing chamber 10, a stirring element 30, a pushing plate 36 and a reset element 90. The mixing chamber 10 is, for example, a cylindrical structure having slots 12 . The inside of the cylindrical structure is preferably hollow, and the slots 12 of the mixing chamber 10 penetrate through the bottom side of the mixing chamber 10 to form an opening. The side wall of the mixing chamber 10 has a plurality of perforations 11, and the perforations 11 are connected to a supply pipe 52. The plurality of food raw material sources (not shown) are, for example, according to the control instructions of the controller 400, through the supply pipe 52. The mixing ratio is input into the mixing chamber 10, in which the colors of the above-mentioned food raw materials can be the same or different. The above mixing ratio can be determined according to the needs of the user. Taking three colors of food raw material sources as an example, the mixing ratio can be equal proportions, that is, the ratio is 1:1:1. In addition, the above-mentioned food raw materials may be, for example, food materials and/or toners. The controller 400 may be, for example, a computer. Since a person with ordinary knowledge in the technical field to which this invention belongs should be able to understand how the controller 400 controls the operation of the food processor 200 and how to make the food raw material source supply the required food raw materials based on the disclosure of this invention, no further explanation is given here. Repeat.

One of the features of this creation is that the controller 400 can adjust and control the flow resistance degree according to the characteristics of the container and the characteristics of the food ingredients. Among them, this creation is based on the shape and size of the squeezing nozzle, the taper of the squeezing nozzle and other container characteristics, as well as the characteristics of the ingredients such as viscosity, density, etc., before the end of the extrusion action, the corresponding responses are pre-implemented. The pumping distance, withdrawal speed and pause time are used to control the flow obstruction. Before the next squeezing action starts, pre-squeezing is performed based on the previous flow blocking parameters. In this way, this invention can solve the problems in traditional technology that the fluid continues to flow out due to residual pressure, making it difficult to control the flow required for extrusion and leaving residual material outside the nozzle, affecting the extrusion shape and making cleaning difficult.

Taking the 5mm round piping nozzle and orange jam as an example, the best parameters are as follows: when the feed speed is 2000mm/min, the extrusion speed is 10mm/min, and the opening of the piping nozzle is 5mm away from the extrusion plane , a macro NC code is applied during retraction, with a retraction distance of 3mm and a retraction speed of 100%. In the subsequent pre-extrusion, a macro NC code with another parameter is also applied, which is advanced The pre-extrusion is 1 second, the moving speed controls 100% of the feed speed, and the extrusion speed is 80%. Among them, if the extrusion speed is not fast enough, the extruded material will be intermittent; if the extrusion speed is too fast, there will be too much extruded material at the mouth of the extrusion head 60 . Taking the 5mm round piping nozzle and salad dressing as an example, the best parameters are as follows: when the feed speed is 3400mm/min, the extrusion speed is 20mm/min, and the opening of the piping nozzle is 4mm away from the extrusion plane , a macro NC code is applied during retraction, with a retraction distance of 1mm and a retraction speed of 100%. In the subsequent pre-extrusion, a macro NC code with another parameter is also applied, which is advanced The pre-extrusion is 0 seconds, the moving speed controls the feed speed 100%, and the extrusion speed is 80%. Similarly, if the extrusion speed is not fast enough, the extruded material will be intermittent; if the extrusion speed is too fast, too much material will be extruded from the mouth of the extrusion head 60 .

The stirring element 30 of the computer numerically controlled flow blocking system 100 of the present invention is rotatably installed in the mixing chamber 10, and is connected to the driving motor 500 through the rod 31 to stir the above-mentioned food raw materials, so that the stirred mixture has corresponding characteristics. Colors in the above mixing proportions.

The pushing plate 36 of the computer numerically controlled flow blocking system 100 of this invention is connected to the piston rod 610 of the piston cylinder 600, and is displaceably disposed in the mixing chamber 10 by the piston cylinder 600 extending or retracting the piston rod 610. There is a through hole 13 in the center of the push plate 36. The push plate 36 is movable and airtightly connected to the stirring element 30 through the through hole 13, and is displaced along the stirring element 30 in the mixing chamber 10, thereby The above-mentioned stirred mixture is extruded out of the flower mouth 66 of the extrusion head 60 . The shape of the pushing plate 36 matches the cross-sectional shape of the mixing chamber 10 . For example, if the mixing chamber 10 is cylindrical, the pushing plate 36 is circular, so that the periphery of the pushing plate 36 can be close to the inner wall of the mixing chamber 10 . In order to obtain a better adhesion effect, a rubber ring may be provided around the periphery of the pushing plate 36 , and when the pushing plate 36 is displaced, the rubber ring is in close contact with the inner wall of the mixing chamber 10 . In addition, the hole wall of the through hole 13 of the pushing plate 36 can also be provided with a rubber ring, and when the pushing plate 36 is displaced along the stirring element 30, the pushing plate 36 can be tightly attached to the stirring element 30 with the rubber ring.

In detail, the top of the mixing chamber 10 has two perforations, and the wall of the perforations is also preferably provided with a rubber ring. One end of the rod 31 is connected to the stirring element 30, and the other end of the rod 31 is connected through one of the The through hole penetrates from the inside to the outside of the mixing chamber 10 and is connected to the driving motor 500 located outside the mixing chamber 10 . The piston cylinder 600 is located outside the mixing chamber 10 , and the piston rod 610 of the piston cylinder 600 passes through another through hole from the outside to the inside of the mixing chamber 10 and is connected to the pushing plate 36 . The drive motor 500 and the piston cylinder 600 perform rotational stirring or telescopic displacement through control instructions of the controller 400 of the food processor 200, for example. Since a person with ordinary knowledge in the technical field to which this invention belongs should be able to understand how the controller 400 controls the drive motor 500 and the piston cylinder 600 to stir and extrude the food raw materials based on the disclosure of this invention, no further details will be described here.

This creation is to extrude the mixture in the mixing chamber 10 from the nozzle 66 of the extrusion head 60 by moving the pushing plate 36. After the extrusion is completed, even though the pushing plate 36 has stopped displacement, at this time The mixture in the mixing chamber 10 will still continue to move toward the extrusion head 60 due to inertia, so excessive and unexpected mixture may be extruded from the flower nozzle 66 . In order to solve this problem, the flow blocking system of this invention is equipped with a reset element 90, which can allow the pushing plate 36 to move in the flow blocking direction D (opposite to the displacement direction during extrusion) when extrusion is completed, so it can be avoided Excess mixture is extruded from the flower nozzle 66, which can improve the extrusion quality and maintain the extrusion cost and efficiency.

The reset element 90 is disposed between the piston cylinder 600 and the mixing chamber 10. When the pushing plate 36 is displaced, the reset element 90 causes the piston cylinder 600 to move to an extrusion position according to an extrusion signal from the controller 400. When the pushing plate 36 stops displacing, the reset element 90 moves the piston cylinder 600 to a flow blocking position according to a flow blocking signal from the controller 400, thereby driving the pushing plate 36 to block the flow in the direction D (opposite to that during extrusion). (displacement direction), so that the mixture can be flush or recessed in the flower mouth 66 of the extrusion head 60.

In the first aspect of the reset element in this invention, please see Figures 11 and 12. The reset element 90 includes a spring 93, a first magnetic component 91 disposed on the bottom side of the piston cylinder 600, and a second magnetic component 92. Located on the top side of the mixing chamber 10. The first magnetic component 91 and the second magnetic component 92 magnetically attract or repel each other according to the extrusion signal or flow blocking signal of the controller 400, so that the spring 93 is in a compressed state when the pushing plate 36 is displaced. A compression elastic force is accumulated (Fig. 11), and when the push plate 36 stops displacing, the compression elastic force is released according to the flow blocking signal, so that the piston cylinder 600 moves to the flow blocking position in the flow blocking direction D and a moving speed (Fig. 12). The spring 93 may be, for example, an adjustable spring, whereby the distance and/or speed of the piston cylinder 600 moving in the flow blocking direction D can be adjusted by adjusting the compression elastic force of the spring 93 . The spring 93 may be, for example, a torsion spring or a compression spring, but is not limited thereto.

In the second aspect of the reset element in this invention, please see Figures 13 and 14. The reset element 90 is an electric screw rod 94 provided on one of the piston cylinder 600 and the mixing chamber 10, and is screwed to the piston cylinder 600 and the mixing chamber 10. mix On the screw hole 95 of the other part of the combined cavity 10, when the pushing plate 36 is displaced according to the extruding signal of the controller 400, the piston cylinder 600 is moved to the extruding position (Fig. 13), and when the pushing plate is displaced, When the displacement of 36 stops, the piston cylinder 600 moves to the flow blocking position at a moving speed in the flow blocking direction D according to the flow blocking signal (Fig. 14). Specifically, when the controller 400 sends an extrusion signal, the electric screw 94 will rotate according to the extrusion signal and rotate toward the screw hole 95 of the piston cylinder 600, so that the distance between the mixing chamber 10 and the piston cylinder 600 is reduced (even The distance between the mixing chamber 10 and the piston cylinder 600 approaches 0). At this time, the piston cylinder 600 is in the extrusion position, and the pushing plate 36 can be pushed and displaced by the piston rod 610 to squeeze the mixture from the nozzle 66 of the extrusion head 60. out. After the extrusion is completed, the electric screw 94 rotates according to the flow resistance issued by the controller 400, causing the piston cylinder 600 to move in the flow resistance direction D and the distance from the mixing chamber 10 becomes larger. At this time, the piston cylinder 600 will drive the piston. The rod 610 also moves in the flow blocking direction D, so that the mixture in the mixing chamber 10 can be prevented from continuing to move toward the extrusion head 60 due to inertia. In addition, the screw connection position of the electric screw rod 94 and the screw hole 95 can also be adjusted through the controller 400 to adjust the distance and/or speed of the piston cylinder 600 moving in the flow blocking direction D.

As shown in Figure 10, this food processor 200 includes a base 220, a first movable frame 230, a second movable frame 240 and a controller 400. The computer numerical control flow blocking system 100 is located on the second movable frame 240. The extrusion head 60 for decoration processing is detachably connected. The base 220 includes slide rails 221 on both sides and a bearing surface 222. The controller 400 is used to control the movements of the first mobile frame 230 and the second mobile frame 240 . In addition, the shape of the first movable frame 230 may be, for example, U-shaped, and both ends of the first movable frame 230 are disposed on the slide rails 221 on both sides of the base 220 so that the first movable frame 230 can move along the Move back and forth in the x-axis direction. The first movable frame 230 may further include an upper slide rail 232, and the second movable frame 240 may be disposed on the upper slide rail 232 of the first movable frame 230, so that the second movable frame 240 can move along the y-axis direction. Move back and forth. In addition, the first moving frame 230 may further include rollers to facilitate the reciprocating movement of the slide rails 221 on both sides along the x-axis direction, and the second moving frame 240 may also include rollers to facilitate the reciprocating movement on the upper slide rail 232 along the y-axis direction. Move back and forth. Continuation Therefore, the extrusion head 60 may be, for example, a forward decoration processing extrusion head and/or a lateral decoration processing extrusion head. The extrusion head 60 can, for example, be used to accommodate viscous, semi-liquid or semi-fluid food materials, such as butter, frosting, chocolate, jam or dough, and the mixing chamber 10 can be connected by means of threads, latches or magnetic attraction. The second moving frame 240 allows the extrusion head 60 to reciprocate along the z-axis direction. The structure of the above-mentioned food processor 200 is only an example and is not intended to limit the invention. Since the type and structure of the food processor 200 are not the focus of this invention, as long as any food processor 200 can perform the food extrusion process, it should fall within the scope of protection claimed by the present invention, so it will not be described again here.

Specifically, in the computer numerically controlled flow blocking system 100 of the present invention, the first connecting member 40 is located on the bottom side of the mixing chamber 10 , and the second connecting member 62 is located on the top side of the extrusion head 60 . Thereby, the mixing chamber 10 can be detachably connected to the second connecting member 62 of the extrusion head 60 via the first connecting member 40 , and the position of the opening of the mixing chamber 10 corresponds to the guide groove 64 of the extrusion head 60 . The first connecting member 40 may be, for example, the second connecting member 62 connected to the extrusion head 60 by magnetic connection. One of the first connecting member 40 and the second connecting member 62 is an electromagnet or an iron piece, and the other is an iron piece or a magnet, or both are electromagnets that can produce opposite magnetism. If the computer numerically controlled flow blocking system 100 of the present invention is used in an automated food extrusion system, the computer numerically controlled flow blocking system 100 can, for example, be installed on a robotic arm, preferably a multi-axis robotic arm, such as the above-mentioned CNC food The second moving frame 240 of the processing machine can meet the various angle requirements of food extrusion. This invention uses electromagnet magnetic attraction to detachably connect the mixing chamber 10 and the extrusion head 60. Therefore, the extrusion head 60 can be accurately and quickly connected to the mixing chamber 10 without installing additional fixing devices, thereby greatly reducing the cost. The time required to replace the extrusion head 60. Moreover, this invention only needs to cancel the magnetism of the electromagnet, so that the extrusion head 60 can be dropped into the extrusion head placement frame 210, so the extrusion head 60 can be quickly disassembled. In addition, the bottom side of the mixing chamber 10 may have a sealing gasket 18 , which is made of, for example, silicone, and the extrusion head 60 has a sealing groove 19 , and the sealing groove 19 corresponds to the sealing gasket 18 , so that the mixing chamber 10 can The extrusion head 60 is tightly connected to prevent food raw materials from leaking.

For example, in an implementation aspect of the first embodiment, the first connecting member 40 is, for example, an electromagnet, and the second connecting member 62 of the extrusion head 60 is, for example, made of iron material, such as an iron plate. Conductive lines 15 can be respectively arranged on the mixing chamber 10. The first end of the conductive lines 15 of the mixing chamber 10 is electrically connected to the first connector 40, and the second end of the conductive lines 15 of the mixing chamber 10 is electrically connected to the power supply. source. Among them, in order to keep the diagram concise, the power supply source is not shown in the diagram. When the first connecting member 40 of the computer numerically controlled flow blocking system 100 of the present invention generates magnetism, it can magnetically attract the second connecting member 62 of the extrusion head 60 to be used. If you want to replace the extrusion head 60, you can first cancel the power supply and demagnetize the first connecting member 40, so that the extrusion head 60 to be removed is separated from the first connecting member 40. Then, the food processor 200 moves the computer numerically controlled flow blocking system 100 to the extrusion head 60 to be used, and then supplies power to attract the extrusion head 60 to be used by causing the first connecting member 40 to generate magnetism.

In another implementation aspect of the first embodiment, the first connecting member 40 is, for example, an electromagnet, and the second connecting member 62 of the extrusion head 60 is, for example, an electromagnet. When the mixing chamber 10 is connected to the extrusion head 60, the second connector 62 of the extrusion head 60 can be electrically connected to the second end of the conductive circuit 15 of the mixing chamber 10, thereby supplying power to the components on the mixing chamber 10 through the power supply source. The first connecting piece 40 generates magnetism. In other words, when the first connecting member 40 of the computer numerically controlled flow blocking system 100 of the present invention contacts the extrusion head 60, both the first connecting member 40 and the second connecting member 62 can generate magnetism and have opposite magnetic poles, for example, respectively The S pole and the N pole are used to attract the second connecting member 62 of the extrusion head 60 to be used by magnetic force. If you want to replace the extrusion head 60, you can first cancel the power supply and demagnetize the first connecting member 40 and the second connecting member 62 so that the extruding head 60 to be removed can be separated from the first connecting member 40, and then the food The processing machine 200 then moves the position of the computer numerically controlled flow blocking system 100 and supplies power to attract another extrusion head 60 to be used by causing the first connecting member 40 and the second connecting member 62 to generate magnetism.

In addition, please refer to Figures 6 and 7. In the second embodiment of the present invention, the mixing chamber 10 includes an extension plate 17 pivotally connected to the bottom side wall of the mixing chamber 10, and the extension plate 17 is connected to a torsion spring. The rotating shaft is pivotally connected to the side wall of the bottom side of the mixing chamber 10 . The extension plate 17 is, for example, substantially perpendicular to the side wall of the mixing chamber 10 in the non-pivoted state due to the restoring force of the spring, which can prevent the extension plate 17 from interfering with the mixing chamber 10 connecting to the extrusion head 60 .
