Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of bagged food packaging equipment technology, and more specifically, to a clamping device for bagged food production. Background Technology

[0002] In the current technology, many materials are gradually being packaged, sealed, stored and transported in bottles or bags; materials containing liquids or slurries, such as kimchi and sauces containing juice, are mostly packaged and transported in material bags; the conventional operation process is to first take the material bag, then open the material bag, fill the material, seal the material bag, transfer and store it in the warehouse, and finally transport it to the area of ​​use.

[0003] Taking sauce filling as an example, the material bags are generally made of plastic, and are soft bags, often stacked in piles. Before filling, the material bags need to be opened to facilitate the filling. Before filling, equipment has gradually replaced manual labor for clamping and opening the material bags. Currently, there are many types of material bags, especially for some small enterprises with limited funds and fewer product varieties. After adopting equipment, if the material bag model changes, the currently installed equipment cannot be used for multiple models of material bags, resulting in idle equipment. It is necessary to add new equipment or parts or modify old equipment to accommodate new products, which increases the investment cost of equipment and reduces the overall utilization rate of equipment. Therefore, it is necessary to improve and optimize the existing technology to reduce enterprise costs and improve equipment utilization. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a clamping device for bagged food production, which solves the problem in the prior art that some enterprises with limited financial strength have poor versatility of packaging equipment used for material bags and low overall utilization rate.

[0005] According to one aspect, at least one embodiment of this disclosure provides a clamping device for bagged food production, comprising:

[0006] frame;

[0007] A turntable is rotatably mounted on the frame;

[0008] The clamping unit is a plurality of units, each of which is used to clamp a material bag;

[0009] The gripping unit includes two symmetrically distributed robotic arms, each robotic arm comprising:

[0010] A clamping arm is oscillating relative to the turntable. The clamping arm has a clamping part with an arc-shaped surface, which is used to abut or release the abutment from the material bag.

[0011] The clamping hand is rotatably configured relative to the clamping arm. After the clamping hand rotates, it clamps or unclamps the material bag.

[0012] For example, in at least one embodiment of the present disclosure, a clamping device for bagged food production includes a sliding hole on the clamping arm and further comprises:

[0013] Sliding component one is slidably disposed relative to the frame, and the sliding component one has a sliding column one, which is slidably disposed within the sliding hole one.

[0014] For example, in at least one embodiment of the present disclosure, a clamping device for bagged food production includes a second sliding hole on the clamping hand, and further comprises:

[0015] The second sliding member is slidably disposed on the clamping arm. The second sliding member has a second sliding post, which is slidably disposed within the second sliding hole.

[0016] For example, in at least one embodiment of this disclosure, a clamping device for producing bagged food further includes:

[0017] A support frame is mounted on the machine frame and is located on the side of the turntable;

[0018] An opening component one is swaying relative to the upright frame;

[0019] The second opening is swaying relative to the upright, and the swaying direction of the first opening is opposite to that of the second opening;

[0020] Several suction cups are respectively installed on the first opening and the second opening. After the first opening and the second opening swing, the suction cups adsorb or release the material bag.

[0021] For example, in at least one embodiment of this disclosure, a clamping device for producing bagged food further includes:

[0022] The support arm is rotatable and slidable relative to the frame, and the support arm is located above the turntable;

[0023] Two support members are slidably mounted on the support arm, and the sliding directions of the two support members are opposite.

[0024] After the support arm slides, the support piece can be inserted into the material bag or removed from insertion.

[0025] For example, in a clamping device for bagged food production provided in at least one embodiment of this disclosure, the center line of rotation of the support arm coincides with the center line of rotation of the turntable.

[0026] For example, in at least one embodiment of this disclosure, a clamping device for producing bagged food further includes:

[0027] The guide rail is mounted on the support arm;

[0028] Two support frames are slidably mounted on the support frames, and one of the support members is mounted on one of the support frames;

[0029] The hinged seat is slidably disposed relative to the support arm;

[0030] The connecting rod is hinged at one end to the hinge seat and at the other end to the support frame.

[0031] For example, in a clamping device for bagged food production provided in at least one embodiment of this disclosure, the support frame is L-shaped, the support frame has a short portion and a long portion, the short portion is hinged to the connecting rod, and the support member is disposed on the end of the long portion away from the short portion.

[0032] For example, in a clamping device for bagged food production provided in at least one embodiment of this disclosure, the mouth support includes a vertical section and a side extension section fixedly connected to each other, and the two side extension sections on the two mouth supports are inclined in a direction away from each other; after the mouth support arm slides, the vertical section inserts into or cancels insertion into the material bag.

[0033] The beneficial effects of the embodiments disclosed herein are as follows:

[0034] In this disclosure, a clamping space for holding material bags is formed between two robotic arms. When the slider slides, it drives the slide column to move synchronously. The slide column slides within the slide hole, thereby causing the clamping arm to rotate on the turntable. The two clamping arms in the same clamping unit rotate in opposite directions. When the clamping arm rotates, it drives the clamping part and the clamping hand to move synchronously, thereby adjusting the gap between the two robotic arms and the size of the clamping space. This allows the clamping device to hold material bags of different sizes and models, improving the applicability of the clamping device.

[0035] When the robotic arm grips a material bag, the material bag has two planes, namely the first plane and the second plane. The first plane of the material bag first contacts the arc-shaped surface of the gripping part, and then an external force is applied to drive the second slider to slide towards the gripping arm. The second slider drives the second sliding column to move synchronously. The second sliding column slides in the second sliding hole, and then the second sliding column drives the gripper to gradually approach the second plane until the gripper makes squeezing contact with the second plane. At this time, the material bag is clamped and fixed between the gripping part and the gripper, completing the gripping of the material bag. When the gripping arm rotates to adjust the size of the bag clamping space, the first plane always contacts the arc-shaped surface of the gripping part. The arc-shaped surface is used to prevent the gripping part from leaving indentations or damaging the first plane when the material bag is clamped, which could cause subsequent sealing problems. After the material bag is clamped in place, the turntable rotates to move the material bag to the next operation step; an external force is applied to drive the second slide to slide away from the clamping arm, the second slide drives the second slide column to move synchronously, the second slide column slides in the second slide hole, the second slide column drives the clamping hand to gradually move away from the second plane, releasing the clamping of the material bag.

[0045] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0046] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0047] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0048] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0050] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] like Figures 1-6 As shown, a clamping device for producing bagged food is illustrated in a first embodiment of this disclosure.

[0052] In some examples, the clamping device includes a frame 1, a turntable 2, a clamping arm 3, and a clamping hand 7. The clamping arm 3 has a clamping part 4 with an arc-shaped surface 5. One clamping arm 3 and one clamping hand 7 form a robotic arm. Two symmetrically distributed robotic arms form a clamping unit. One clamping unit is used to clamp a material bag 6. The number of clamping units is several. The structure of the clamping arm 3 and the clamping hand 7 is refined by adding a sliding hole 8 to the clamping arm 3 and a sliding hole 11 to the clamping hand 7. It also includes a sliding component 9 and a sliding component 12. The sliding component 9 has a sliding post 10, and the sliding component 12 has a sliding post 13. A clamping space for clamping the material bag 6 is formed between the two robotic arms.

[0053] For example, such as Figures 1-2 and Figures 4-5 As shown, when the slider 9 slides, it will drive the slider 10 to move synchronously. The slider 10 slides in the sliding hole 8, which in turn drives the clamping arm 3 to rotate on the turntable 2. The two clamping arms 3 in the same clamping unit rotate in opposite directions. When the clamping arm 3 rotates, it will drive the clamping part 4 and the clamping hand 7 to move synchronously, thereby adjusting the gap between the two robotic arms and adjusting the size of the bag clamping space, so that the clamping device can clamp material bags 6 of different sizes and improve the applicability of the clamping device.

[0054] When the robotic arm grips the material bag 6, the material bag 6 has two planes, namely the first plane and the second plane. The first plane of the material bag 6 first contacts the arc surface 5 of the gripping part 4, and then an external force is applied to drive the slider 12 to slide towards the gripping arm 3. The slider 12 drives the slider 13 to move synchronously. The slider 13 slides in the sliding hole 11, and then the slider 13 drives the gripper 7 to gradually approach the second plane until the gripper 7 makes a squeezing contact with the second plane. At this time, the material bag 6 is clamped and fixed between the gripping part 4 and the gripper 7, completing the gripping of the material bag 6. When the gripping arm 3 rotates to adjust the size of the bag clamping space, the first plane always contacts the arc surface 5 of the gripping part 4. The arc surface 5 is used to prevent the gripping part 4 from leaving indentations or damaging the first plane when the material bag 6 is clamped, which could cause subsequent sealing problems. After the material bag 6 is clamped in place, the turntable 2 rotates to move the material bag 6 to the next operation step; an external force is applied to drive the second slide 12 to slide away from the clamping arm 3, the second slide 12 drives the second slide column 13 to move synchronously, the second slide column 13 slides in the second slide hole 11, the second slide column 13 drives the clamping hand 7 to gradually move away from the second plane, releasing the clamping of the material bag 6.

[0055] like Figures 1-6 As shown, a clamping device for producing bagged food is illustrated in a second embodiment of this disclosure.

[0056] In some examples, the clamping device includes a frame 1, a turntable 2, a clamping arm 3, and a clamping hand 7. In this embodiment, the frame 1, the turntable 2, the clamping arm 3, and the clamping hand 7 perform the same functions as in the first embodiment, so they will not be described again here.

[0057] For example, such as Figures 1-2 and Figures 4-6As shown, the clamping device has been optimized by adding a stand 14, an opening component 15, an opening component 2 16, and a suction cup 17. During operation, the clamping unit moves the clamped material bag 6 to the side of the stand 14, applying external force to drive the opening components 15 and 2 16 to swing simultaneously in opposite directions and gradually approach each other. This continues until the suction cup 17 (defined as plate one) of the opening component 15 makes contact with the first plane and the suction cup 17 (defined as plate two) of the opening component 2 16 makes contact with the second plane, at which point the swinging of the opening components 15 and 2 16 stops. Plate one and plate two are symmetrically positioned... The suction cups 17 are connected to an external compressed air power unit and are made of rubber. The suction cups 17 create negative pressure adsorption on the flat surface of the material bag 6. Then, an external force is applied to drive the opening components 15 and 16 to swing simultaneously in a direction away from each other. The first opening component, adsorbing the first flat surface, gradually moves away from the second flat surface. After swinging a certain angle, the opening components 15 and 16 stop swinging, simultaneously cutting off the negative pressure adsorption force on the suction cups 17. At this point, the first opening component separates from the first flat surface, and the second opening component separates from the second flat surface, completing the opening of the material bag 6. As the first and second flat surfaces move away, the two sides of the material bag 6 gradually approach each other. At this point, the material bag 6 slides against the arc-shaped surface 5 of the clamping part 4, reducing sliding wear. Furthermore, an external force can be applied to drive the two clamping arms 3 in the same clamping unit to rotate a certain angle in a direction closer to each other, adapting to the opening operation of the material bag 6 and preventing the material bag 6 from separating from the clamping part 4 and falling off.

[0058] After the material bag 6 is opened, the drive turntable 2 rotates, moving the opened material bag 6 to the next work process for filling or filling. During the transfer, a support arm 18 and two support pieces 19 are added to the frame 1. The two support pieces 19 ensure that the material bag 6 is moved to the next work process in an open state. The center line of rotation of the support arm 18 is aligned with the center line of rotation of the turntable 2 to ensure that the turntable 2 and the support pieces 19 are in a relatively stationary state when the material bag 6 is transferred, ensuring the consistency of the opening state of the material bag 6. During operation, after the suction cup 17 separates from the material bag 6, an inner cavity for placing materials is formed between the first plane and the second plane. When an external force is applied to drive the turntable 2, when the opened material bag 6 is moved to a preset position, the support arm 18 begins to slide downwards a certain distance and then stops sliding, inserting the two support pieces 19 into the inner cavity. An external force is applied to drive the two support pieces 19 to slide a certain distance away from each other and then stop sliding, preventing the first plane and the second plane from getting closer to each other. After the mouth support 19 is inserted into the inner chamber, the drive turntable 2 and the mouth support arm 18 rotate synchronously and in the same direction at a certain angle. The mouth support arm 18 gradually moves away from the stand 14, moving the material bag 6 to the material filling or filling operation area to ensure smooth material filling or filling. Then, an external force is applied to drive the two mouth support 19 to move closer to each other, driving the mouth support arm 18 to slide upward away from the material bag 6, and the mouth support 19 is withdrawn from the inner chamber. Then, the mouth support arm 18 rotates at a certain angle towards the stand 14 to perform the next mouth support operation, and this cycle is repeated continuously.

[0059] like Figures 1-7 As shown, a clamping device for producing bagged food is illustrated in a third embodiment of this disclosure.

[0060] In some examples, the clamping device includes a frame 1, a turntable 2, a clamping arm 3, and a clamping hand 7; further, a stand 14, an opening component 15, an opening component 2 16, and a suction cup 17 are added; a support arm 18 and two support components 19 are also added; in this embodiment, the frame 1, turntable 2, clamping arm 3, clamping hand 7, stand 14, opening component 15, opening component 2 16, suction cup 17, support arm 18, and two support components 19 play the same role as in its second embodiment, so they will not be repeated here.

[0061] For example, such as Figures 1-3 and Figure 7As shown, the clamping device has been optimized by adding a guide rail 20, a support frame 21, a hinge seat 22, and a connecting rod 23. During operation, when the material bag 6, which has separated from the suction cup 17 and is in an open state, is moved to the bottom of the support member 19, an external force is applied to drive the hinge seat 22 to slide downward. The hinge seat 22, through the hinged connecting rod 23, drives the two support frames 21 to move away from each other, and the support frames 21 drive the support member 19 to move synchronously. The two connecting rods 23 are symmetrically arranged with respect to the hinge seat 22, ensuring the symmetry and stability of the sliding of the two support frames 21 and the two support members 19.

[0062] Meanwhile, the structure of the support frame 21 and the spout member 19 is refined. The support frame 21 is L-shaped and has a short part 24 and a long part 25. The short part 24 is hinged to the connecting rod 23. The spout member 19 is located on the end of the long part 25 away from the short part 24. The spout member 19 includes a vertical section 26 and a side extension section 27 that are fixedly connected to each other. The two side extension sections 27 on the two spout members 19 are inclined in a direction away from each other. After the spout arm 18 slides, the vertical section 26 is inserted into the material bag 6 or is not inserted. The L-shaped design of the support frame 21 avoids the spout arm 18 from occupying the upper area of ​​the material bag 6, which facilitates the subsequent filling or filling of materials. The refined spout member 19, with the help of the inclined side extension section 27, also avoids the upper area of ​​the material bag 6, ensuring the smooth progress of subsequent operations.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
