Description

Technical Field

[0001] This utility model belongs to the field of packaging machinery technology, and in particular relates to a card-attaching packaging machine for socks. Background Technology

[0002] A card folding and labeling machine is a type of packaging machinery commonly used for products such as towels, socks, and gloves. Its basic operation involves taking a printed paper card with a certain thickness and rigidity as the packaging material, folding it at a predetermined position to form a U-shape, then inserting the item to be packaged into the opening of the U-shape, and finally securing the two ends of the U-shape to the packaged item. In some cases, retailers may wish to display these goods on shelves in a hanging manner, thus requiring the addition of a hook to the paper card.

[0003] The applicant has previously applied for patents in this field, including a utility model patent entitled "Paper Card Hook Device" (patent number 202322799090.5). This prior art includes a sheet-like hook with an acute-angled head and an arc-shaped tail, as well as a base, a housing, and a push plate. The housing is fixedly mounted on the base, and the push plate is telescopically mounted on the base and extended by a drive mechanism. The housing is located above the push plate, and the bottom surface of the housing is in clearance fit with the main body of the top surface of the push plate. The housing has a transparent cavity, and several hooks are placed in the cavity in an up-and-down stacked manner. The front end of the top surface of the push plate has a recessed portion, the size of which matches the tail of the hook, and the depth of the recessed portion is not greater than the thickness of the hook. When the push plate retracts, the position of the recessed portion corresponds to the rear of the housing cavity. There is also a utility model patent titled "Card Folding Mechanism," application number 202422475640.X. This prior art includes a worktable for receiving single paper cards transferred from other mechanisms. The worktable has a notch at its rear end, and a pivotally connected card folding head is located below the notch. The card folding head can rotate relative to the worktable. The rotation stroke of the card folding head is greater than 90°. At the initial end of its rotation stroke, the card folding head is lower than the worktable. At the end of its rotation stroke, the card folding head at least partially fills and covers the notch of the worktable. There are baffles on the left and right sides of the worktable, and the lower edge of the baffles is higher than the worktable. The card folding head has a rotation mechanism that drives the card folding head to rotate forward or backward. Summary of the Invention

[0004] The purpose of this invention is to provide a card-attaching packaging machine for socks and similar items, based on the aforementioned prior art.

[0005] The technical solution adopted by this utility model is as follows: a card-attaching packaging machine for socks includes a worktable with a conveyor belt. Items to be packaged are placed on the conveyor belt and conveyed forward. A card-folding mechanism is provided in front of the conveyor belt, and a card-issuing mechanism and a label-attaching mechanism are respectively provided on the left and right sides of the card-folding mechanism. The machine is characterized in that: a first clamping member is also provided in front of the conveyor belt for clamping the item to be packaged that has already had its card folded or its card folded and labeled. The first clamping member carries the item to be packaged along a first track, which is perpendicular to the conveyor belt. The first clamping member has a first stop position and a second stop position on the first track, the second stop position being farther from the first stop position. A hinged thread-attaching mechanism is provided at the second stop position. A second clamping member, moving along the second track, is also provided at the first stop position for clamping the item to be packaged at the first stop position. A hook mechanism is provided on one side in front of the second track.

[0006] The second track moves in the opposite direction to the conveyor belt.

[0007] The card-folding mechanism includes a card-folding head disposed below the worktable, which can rotate relative to the worktable surface. The rotation stroke of the card-folding head is greater than 90°. At the initial end of its rotation stroke, the card-folding head is lower than the worktable surface. At the end of its rotation stroke, the card-folding head at least partially fills and covers the gap in the worktable surface. The rotation stroke of the card-folding head is controlled by a motor. By controlling the rotation angle of the motor, the card-folding head has two different amplitudes at the end of its rotation stroke.

[0008] This utility model incorporates both a labeling mechanism and a flexible stitching mechanism, representing two different methods of securing the packaged item. The labeling mechanism is essentially a glue gun, similar to the principle of a stapler, fixing both sides of the U-shaped paper card to the packaged item. The flexible stitching mechanism, similar to the principle of a sewing machine, uses thread to fix both sides of the U-shaped paper card to the packaged item. Both are commonly used methods, and users can choose one according to their needs. When using the labeling mechanism, the socks to be packaged move forward on a conveyor belt. The card issuing mechanism pre-places the paper card at a set position. After the sock reaches the paper card, the card folding mechanism folds the paper card into a U-shape to cover one end of the sock. Then, the labeling mechanism inserts glue needles into the paper card to secure it to the packaged item. The first clamping member holds the sock with the paper card and moves it along the first track to the first stop position, where it is then held by the second clamping member and moves along the second track to the hook mechanism, where the hook mechanism completes the hooking operation. When a hinged threading mechanism is used, the socks to be packaged move forward on the conveyor belt. The card issuing mechanism pre-places the paper card at a set position. After the socks reach the paper card, the card folding mechanism folds the paper card into a U-shape to cover one end of the sock. The first clamping member clamps the sock with the paper card and moves along the first track to the second stop position. The hinged threading mechanism then threads the paper card to fix it to the packaged item. Afterward, the first clamping member returns to the first stop position and is clamped by the second clamping member. The sock then moves along the second track to the hooking mechanism, where the hooking mechanism completes the hooking operation.

[0009] In this invention, the movement of the socks actually consists of three segments: movement along the conveyor belt, movement along the first track, and movement along the second track. These three tracks are perpendicular to each other sequentially. Since the second track is in the opposite direction to the conveyor belt, the final segment is essentially a reversal back to the initial direction. This movement method, when applied to the overall machine layout, allows for a more compact design and saves floor space.

[0010] Through in-depth research, the applicant discovered that the requirements for paper cards differ between the two methods of labeling and sew-knot stitching. Relatively speaking, with sew-knot stitching, the upward-facing side of the paper card needs to be flatter, meaning the angle with the horizontal plane should be as small as possible; with labeling, the upward-facing side of the paper card needs to have a certain degree of curvature, meaning it forms a certain angle with the horizontal plane. Therefore, the rotation angle of the folding head in this utility model is controllable. When using sew-knot stitching, the folding head has a larger rotational stroke at the end to fold the paper card flatter; when using a labeling mechanism, the rotation amplitude of the folding head can be slightly smaller.

[0011] It is evident that this utility model has a reasonable design and compact layout, and can use both nail tags and swivel nails. Attached Figure Description

[0012] Figure 1 , Figure 2 These are structural schematic diagrams of this utility model from different angles. Detailed Implementation

[0013] See Figure 1 , Figure 2 The workbench 1 in this embodiment is composed of several work surfaces. When customers have different needs, some parts of the machine can be added or removed.

[0014] A conveyor belt 2 is installed on the workbench. Socks 00 to be packaged are placed on the conveyor belt and moved from... Figure 1 From the angle, it runs from the upper right to the lower left; in front of the socks, there is a card folding mechanism 4 on the worktable, and a card issuing mechanism 3 on the side, which transports the stacked paper cards 30 one by one to the card folding mechanism; the specific structure of the card issuing mechanism and the card folding mechanism is the same as the previous technical solution, and you can refer to the literature mentioned in the background section of this manual.

[0015] Above the card folding mechanism is a tagging mechanism 5, which may or may not participate in the work as needed.

[0016] A first track 7 perpendicular to the conveyor belt 2 is provided in front of it, and a first clamping member 6 moves along the first track 7. Thus, the movement direction of the first clamping member 6 is perpendicular to the movement direction of the sock on the conveyor belt. After passing through the folding mechanism 4, the sock 00 is clamped and moved by the first clamping member 6, and has two stop positions in front of it: a first stop position 61 with a shorter movement distance and a second stop position 62 with a longer movement distance. It moves to the set stop position as needed.

[0017] In front of the first track 7, corresponding to the second stop position, a hinged thread-pinning mechanism 8 is provided. This hinged thread-pinning mechanism is also existing technology, and in this embodiment, it is a commercially available product. At the first stop position 61, there is a second track 10 perpendicular to the first track, and a second clamping member 9 that moves along the second track. The direction of movement of the second clamping member is from... Figure 1 From an angle perspective, the movement is from the lower left to the upper right, thus reversing the movement of the socks compared to their movement on the conveyor belt. A vibrating sorting disc 12 and a hook insertion mechanism 11 are located on one side of the front end of the second track. After sorting, the hooks are inserted and clamped onto the socks in the second clamping member, completing the entire packaging and securing process.
