Description

Technical Field

[0002] With the advancement of science and technology, the use of mechanized equipment for the production and processing of products has become widespread. Bagging is a common processing method, such as folding disposable gloves, which involves folding them and placing them in a bag. However, in existing mechanical packaging production, to facilitate smooth insertion of the product into the bag, the bag's opening is typically designed to be significantly larger than the product's dimensions. This prevents insertion errors caused by misalignment or wobbling during insertion. This existing method significantly increases material costs and results in a larger overall package size.

[0006] Furthermore, the driving component is a linear driving component that moves along a straight line. A first abutting end is provided on the mounting plate, and a second abutting end is provided on the bagging platform. The driving component moves unidirectionally along a straight line so that it abuts against the first abutting end and the second abutting end in succession, thereby first causing the mounting plate to translate along the second direction and then driving the bagging platform to rotate and swing to a position where the insertion channel is facing the push rod.

The driving plate is slidably assembled on the linear slide through the slider. The linear driver drives the driving plate to drive the driving plate to slide back and forth on the linear slide.

[0009] Furthermore, a support plate is fixed on the mounting plate, and a plurality of support rollers protruding from the upper surface of the support plate are mounted on the support plate, and the bottom surface of the bagging platform abuts against the support rollers.

[0011] Furthermore, the bagging platform is assembled on a mounting flange via a rotating shaft with a bearing, and the mounting flange is fixed to the mounting plate.

[0012] Furthermore, when the bagging platform switches to the facing position, the first abutting surface always abuts against the first pulley, so that the mounting plate and the bagging platform remain in the position after translation in the second direction.

[0013] Furthermore, a vacuum suction hole connected to the insertion channel is provided on the bagging platform; the bagging mechanism also includes a bag supply unit, the bag supply unit includes a material table and a transfer component, the material table is used to store packaging bags, the transfer component has a suction claw, the transfer component sucks the packaging bag on the material table through the suction claw and transfers it to the insertion channel of the bagging platform, and the lower side of the packaging bag located on the insertion channel is adsorbed by the vacuum suction hole, and the suction claw of the transfer component sucks the upper side of the packaging bag to fix the packaging bag on the insertion channel and keep the bag opening in an open state.

These drawings form part of the present disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, one of ordinary skill in the art will understand other possible embodiments and the advantages of the present invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

Therefore, they should not be understood as limiting the present invention.

[0040] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0041] Reference Figures 1 to 6As shown, the present embodiment provides a bagging mechanism suitable for packaging disposable folding gloves. The bagging mechanism includes a pushing portion 10 and a bagging portion 30. The pushing portion 10 has a push rod 11 and can drive the push rod 11 to move back and forth in a first direction to push the product into the bagging portion 30. In the present embodiment, the pushing portion 10 specifically includes a propulsion driver 12, a sliding frame 13, and the push rod 11. The sliding frame 13 is slidable in the first direction. The propulsion driver 12 is driven to connect to the sliding frame 13, and the push rod 11 is fixedly assembled on the sliding frame 13. Of course, in other embodiments, the structure of the pushing portion 10 is not limited to this.

[0042] The bagging part 30 includes a base 34, a mounting plate 31, a driving assembly 32, a first elastic return member 35, a second elastic return member 33 and a bagging platform 20. The mounting plate 31 can be slidably arranged on the base 34 along the second direction. The first direction is perpendicular to the second direction. Specifically, the first direction and the second direction are both horizontal directions. For example, in a three-axis coordinate system, the first direction is the X-axis direction and the second direction is the Y-axis direction. More specifically, a linear guide rail 341 extending along the second direction is provided on the base 34. The bottom of the mounting plate 31 can be slidably assembled on the linear guide rail 341 through the first slider 312 to achieve a slidable assembly.

[0043] The first elastic return member 35 is connected to the base 34 and the mounting plate 31. Specifically, the first elastic return member 35 is a tension spring, and its two ends are respectively connected to the base 34 and the mounting plate 31; the bagging platform 20 is rotatably mounted on the mounting plate 31. Specifically, the bagging platform 20 also rotates on a horizontal plane; more specifically, the bagging platform 20 is assembled on a mounting flange 313 through a rotating shaft 23 with a bearing, and the mounting flange 313 is fixed to the mounting plate 31. The rotatable assembly of the bagging platform 20 is realized. The second elastic return member 33 is connected to the mounting plate 31 and the bagging platform 20. Specifically, the second elastic return member 33 is also a tension spring, and its two ends are respectively connected to the mounting plate 31 and the bagging platform 20.

[0044] The bagging platform 20 is provided with an insertion channel 21 for placing the packaging bag 1. Specifically, the insertion channel 21 is an insertion groove provided on the upper surface of the bagging platform 20. During the bagging operation, the packaging bag 1 is fixed in the insertion channel 21 of the bagging platform 20, and the bag opening of the packaging bag 1 faces the pushing part 10.

[0045] In the initial state, the bagging platform 20 is in a diagonal position where the insertion channel is inclined to the first direction under the action of the second elastic return member 33; that is, the insertion channel 21 and the push rod 11 are inclined at a certain angle; so that the push rod 11 is inclined and inserted into the insertion channel 21 when it approaches the bagging platform 20 along the first direction.

[0046] The drive assembly 32 first causes the drive plate 322 to translate in the second direction and then drives the bagging platform 20 to rotate and swing until the insertion channel 21 is directly opposite the push rod 11. Specifically, when the drive assembly 32 is activated, it first causes the mounting plate 31 to translate in the second direction (at this time, the bagging platform 20 is still in the diagonally opposite position). This translation of the mounting plate 31 in the second direction simultaneously causes the bagging platform 20 and the packaging bags 1 thereon to translate together. After the translation is complete, the drive assembly 32 then causes the bagging platform 20 to rotate and swing until it reaches the directly opposite position. In this directly opposite position, the insertion channel 21 is directly opposite the push rod 11, i.e., the insertion channel 21 is parallel to the push rod 11.

[0047] Specifically, when the driving component 32 drives the mounting plate 31 to translate along the second direction, the first elastic return member 35 generates elastic deformation to store energy. When the mounting plate 31 loses the force of the driving component 32, the mounting plate 31 returns under the action of the first elastic return member 35. Similarly, when the driving component 32 drives the bagging platform 20 to rotate and swing to the facing position, the second elastic return member 33 generates elastic deformation to store energy. When the mounting plate 31 loses the force of the driving component 32, the mounting plate 31 returns to the diagonally facing position under the action of the second elastic return member 33.

[0048] The first elastic return member 35 and the second elastic return member 33 are both tension springs, which are simple in structure and easy to implement. Of course, in other embodiments, the first elastic return member 35 and / or the second elastic return member 33 can also be other elastic members, such as the first elastic return member 35 can be a compression spring, and the second elastic return member 33 can be a torsion spring, etc., as long as the first elastic return member 35 can apply the return force in the second direction to the mounting plate 31, and the second elastic return member 33 can apply the force to the bagging carrier 20 to switch it to the diagonal position.

[0049] Based on this, this embodiment also provides a compact bagging method, comprising the following steps:

[0050] S1, provide the bagging mechanism described above, switch the bagging platform 20 to a diagonal position, and transfer the packaging bag 1 to the insertion channel 21 of the bagging platform 20, so that the bag opening of the packaging bag 1 is diagonally opposite to the push rod 11 of the pushing part 10.

[0051] In step S2, the pushing portion 10 uses the push rod 11 to push the product 2 diagonally into the insertion channel 21 of the bagging platform 20, so that one end corner a of the product 2 is inserted into the opening of the packaging bag 1 first. The product 2 is inserted into the opening of the packaging bag 1 with the end corner a (the tip) first. The size of the end corner a is much smaller than the size of the bag opening, effectively ensuring that the product 2 can be smoothly inserted into the bag opening of the packaging bag 1 with a high success rate.

[0052] S3, the driving component 32 drives the mounting plate 31 to translate along the second direction, and the mounting plate 31 drives the bagging platform 20 and the packaging bag 1 thereon to translate together, and the product 2 and the packaging bag 1 undergo lateral relative displacement; so that the product 2 is tightly attached to one side of the bag opening of the packaging bag 1; and more reserved space is provided on the other side of the packaging bag 1 to ensure that the end corner of the product 2 outside the bag opening can be smoothly inserted.

[0053] S4, the driving component 32 drives the bagging platform 20 to rotate and swing to the facing position. During the swing switching process, the front end of the product 2 is completely inserted into the bag opening of the packaging bag 1.

[0054] S5, the pushing part 10 drives the push rod 11 to push the product completely into the packaging bag 1, completing the bagging operation.

[0055] When bagging, product 2 is pushed obliquely so that one end corner a is smoothly inserted into the bag opening, and then the product 2 is moved horizontally so that it is close to one side of the bag opening of the packaging bag 1. Finally, the front end of the product 2 is completely inserted by aligning it (i.e., swinging it to the facing position). In this way, it can be well ensured that the bagging can be smoothly carried out on the basis of reducing the size of the bag opening of the packaging bag 1, thereby achieving compact packaging.

[0056] Specifically, after the bagging operation in step S5 is completed, the finished packaged product on the bagging platform 20 is discharged. Thereafter, the driving assembly 32 returns to its original position, the bagging platform 20 loses the function of the driving assembly 32 and switches to the diagonal position under the action of the second elastic return member 33. Furthermore, the mounting plate 31 loses the function of the driving assembly 32 and returns to its original position in the second direction under the action of the first elastic return member 35, waiting for the next operation.

[0057] Furthermore, in this embodiment, the drive assembly 32 is a linear drive assembly that moves in a straight line. For example, in this embodiment, the drive assembly 32 moves linearly in a first direction. The mounting plate 31 is provided with a first abutting end 311, and the bagging platform 20 is provided with a second abutting end 22. The one-way movement of the drive assembly 32 in the first direction causes it to abut against the first abutting end 311 and the second abutting end 22 in sequence, thereby first causing the mounting plate 31 to translate in the second direction and then causing the bagging platform 20 to rotate and swing to a position where the insertion channel 21 is directly opposite the push rod 11. The above-mentioned structural design uses a single drive assembly 32 to well implement the sequential action of translation and then swing switching, which is simple in structure, reliable in action, and ingenious in design.

[0058] Specifically, the first abutting end 311 is a first pulley mounted on the mounting plate 31, and the second abutting end 22 is a second pulley mounted on the bagging platform 20. The driving assembly 32 includes a driving plate 322, which is provided with a first abutting surface 323 corresponding to the first pulley and a second abutting surface 324 corresponding to the second pulley. Specifically, the front ends of the first abutting surface 323 and the second abutting surface 324 are both inclined guide surfaces. When the first abutting surface 323 initially contacts the first pulley, the inclined guide surface at the front end abuts against the first pulley. As the first abutting surface 323 continues to move, the mounting plate 31 is gradually driven to slide in the second direction until it switches to the right position. Similarly, when the second abutting surface 324 initially contacts the second pulley, the inclined guide surface at the front end abuts against the second pulley. As the second abutting surface 324 continues to move, the bagging platform 20 is gradually driven to swing and switch until it switches to the facing position. The use of the pulleys reduces friction and makes the movement smoother.

[0059] Specifically, when the bagging platform 20 switches to the facing position, the first abutting surface 323 always abuts against the first pulley, so that the bagging platform 20 maintains the position after the translation in the second direction.

[0060] Specifically, the driving assembly 32 includes: a linear driver 321, a slider (defined as a second slider 325) and the driving plate 322. A linear slide 342 is provided on the base 34, and the linear slide 342 extends along a first direction; the driving plate 322 is slidably mounted on the linear slide 342 via the second slider 325; the linear driver 321 drives and connects the driving plate 322 to drive the driving plate 322 to slide back and forth on the linear slide 342; the second abutting surface 324 and the first abutting surface 323 are located on the same side and are distributed up and down; the unidirectional sliding of the driving plate 322 on the linear slide 342 causes the first abutting surface 323 to first abut against the first pulley, driving the mounting plate 31 to translate along the second direction, and then the second abutting surface 324 abuts against the second pulley, driving the bagging platform 20 to rotate and swing to a facing position. With this structure, the bagging part 30 is assembled into a whole.

[0061] Furthermore, a support plate 36 is fixed on the mounting plate 31, and a plurality of support rollers 361 are mounted on the support plate 36 protruding from the upper surface of the support plate 36. The bottom surface of the bagging platform 20 abuts against the support rollers 361 to better support the bagging platform 20 and keep the bagging platform 20 stable.

[0062] Furthermore, the upper and lower sides of the packaging bag 1 on the bagging platform 20 are respectively sucked to maintain the bag opening in an open state. Specifically, the bagging platform 20 is provided with a vacuum suction hole 24 connected to the insertion channel 21. At the same time, the bagging mechanism also includes a bag supply unit, which includes a material table 40 and a transfer assembly 50. The material table 40 is used to store the packaging bag 1. The transfer assembly 50 has a suction claw, which uses the suction claw to suck the packaging bag 1 on the material table 40 and transfer it to the insertion channel 21 of the bagging platform 20. At this time, the vacuum suction hole 24 of the bagging platform 20 sucks the lower side of the packaging bag 1, and the suction claw of the transfer assembly 50 sucks the upper side of the packaging bag 1, thereby fixing the packaging bag 1 and maintaining the open state. At the same time, when the bagging platform 20 changes position (translationally in the second direction and switching from an oblique position to a straight position), when the product 2 is partially inserted into the packaging bag 1, the suction claw of the transfer assembly 50 can break the vacuum and release the suction on the packaging bag 1.

[0063] Of course, in other embodiments, other methods may be used to keep the packaging bag 1 in the expanded state, or if the packaging bag 1 itself can keep the bag opening in the expanded state, there is no need to use other external structures.

[0064] The bagging mechanism disclosed in the present application is very suitable for folding packaging of disposable folding gloves.

[0065] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
