Description

Technical Field

[0001] The utility model relates to the technical field of intelligent manufacturing or shoemaking, in particular to an automatic shoe tongue labeling device with a shoe tongue supply unit. Background Art

[0002] In the shoemaking industry, shoe tongue hot labeling is a part of the production process. The shoe tongue is the part between the bottom of the shoelace and the top of the instep, which plays a role in reducing the friction between the shoelace and the instep. Generally, the shoe tongue is a separate piece of material on the upper. Usually, the label with the brand's LOGO or QR code is printed on the shoe tongue. The shoe tongue labeling device is an automated device that can add labels to the shoe tongue. Its existence can greatly improve the mechanization and automation of shoemaking.

[0003] In the existing technology, a technical solution has been proposed, which uses visual recognition technology to automatically determine the position and orientation of the tongue, and uses a parallel robot to place the label, thereby achieving alignment between the tongue and the label. Using this technology, the position, angle and type of the tongue can be automatically identified, so there is no need to place the tongue in a standardized manner, because even if the tongue is placed at an angle, the parallel robot can be used to adjust the angle of the label so that the tongue and the label are aligned.

[0004] However, the above-mentioned automatic shoe tongue labeling device still has a bottleneck in the number of hot labels that can be applied per unit time. This is because the shoe tongue is randomly supplied to the conveyor and finally supplied to the bottom of the parallel robot at a randomly oriented angle. The parallel robot needs to perform a relatively large movement to match the angle of the shoe tongue. The parallel robot needs more time to perform the above operation, thus affecting the efficiency of the shoe tongue labeling device. In addition, the parallel robot needs to perform complex actions, resulting in a complex structure of the parallel robot, and high manufacturing and later maintenance costs. Utility Model Content

The visual recognition unit 13 includes a square dark box, in which a light source and a camera are arranged. The camera is used to capture the image of the tongue passing under the visual recognition unit 13, and the captured image is sent to a computer for processing and recognition.

[0043] The label supply machine 15 is used to supply labels. The label supply machine 15 is arranged beside the conveyor 12. The label supply machine 15 is usually a label printer, which can print out the required labels promptly and quickly, and automatically supply them to the outside. The printed labels are placed on the label output part, waiting to be taken away; preferably, a slide rail 21 is provided on the fixed frame 11, and the label supply machine 15 is slidably arranged on the slide rail 21, so that the label supply machine 15 can move between the working position and the non-working position, so that the label supply machine 15 can be close to the conveyor 12 when in use, and can be moved out when maintenance or replacement of consumables is required.

[0044] Due to the use of the tongue supply unit 19, the tongue 30 can be supplied regularly, so the tongue 30 placed on the conveyor 12 is basically aligned. At this time, the label picking and placing unit 14 does not need a large position movement and angle rotation to align with the tongue. Therefore, the label picking and placing unit 14 can adopt a simple structure, which will be described later.

[0045] The bonding machine 16, also known as a hot labeling machine or an ironing machine, is arranged downstream of the conveyor 12. The bonding machine 16 is used to fix the label on the shoe tongue. The shoe tongue that has been carrying the label on the conveyor 12 directly enters the bonding machine 16, completes the hot labeling operation in the bonding machine 16, and then is collected.

[0046] The shoe tongue pick-up and placement unit 18 is indirectly arranged on the fixed frame 11, and the shoe tongue pick-up and placement unit 18 is configured to obtain the shoe tongue 30 from the shoe tongue supply unit 19 and place the shoe tongue 30 on the conveyor 12. In the present utility model, the shoe tongue pick-up and placement unit 18 is designed in the form of a mechanical arm, which uses the vacuum adsorption principle to adsorb the shoe tongue, and therefore includes a vacuum suction nozzle 41. The number of the vacuum suction nozzles 41 can be multiple, and there are two in the illustrated embodiment. The vacuum suction nozzle 41 is used to adsorb or release the shoe tongue 30, and two shoe tongues 30 can be processed at the same time. The shoe tongue pick-up and placement unit 18 is not the focus of the description of the present utility model, so its structure is not described in detail.

[0047] The shoe tongue supply unit 19 is arranged on the fixed frame 11, and is used to store and supply the shoe tongue 30. In the illustrated embodiment, there are two shoe tongue supply units 19, and the two shoe tongue supply units 19 are respectively arranged on both sides of the conveyor 12. The shoe tongue supply unit 19 includes a fixed support plate 31, a bottom support assembly 32, a shoe tongue bin 33, a movable support assembly 36 and an actuating motor 37. The fixed support plate 31 is attached to the fixed frame 11, and is used to support the bottom support assembly 32, and the bottom support assembly 32 is fixedly arranged on the fixed frame 11; two shoe tongue bins 33 are arranged side by side on the bottom support assembly 32, and the shoe tongue bins are used to store the stacked shoe tongues 30; and the movable support assembly 36 is used to support the shoe tongues 30 stacked in the vertical direction, and the movable support assembly 36 is sleeved on the shoe tongue bin 33 and is configured to be able to move in the vertical direction under the drive of the actuating motor 37. The movable support assembly 36 can be moved upward in a stepwise manner, thereby gradually pushing the stacked shoe tongues upward, so that after the shoe tongues are taken away one by one, the uppermost shoe tongues always remain on approximately the same plane.

[0048] Preferably, the shoe tongue bin 33 is composed of a fence 35 and an adjustment bar 34, the cross section of the fence 35 along the horizontal plane is arc-shaped, and the adjustment bar 34 is arranged on one side of the fence 35, so that a space for storing the shoe tongue 30 is formed between the adjustment bar 34 and the fence 35. The adjustment bar 34 is configured to be movable relative to the fence 35 to adjust the size of the space. In this way, the shoe tongue bin can be suitable for shoe tongues of different sizes, and the shoe tongue can be constrained in position.

[0049] The label picking and placing unit 14 includes: a driving part 22, which is fixedly arranged on the fixed frame 11; a first horizontal arm 23, which is arranged on the driving part 22 and is configured to be able to rotate around an axis along a horizontal plane; a second horizontal arm 24, which is arranged on the first horizontal arm 23 and is configured to be able to rotate around an axis along a horizontal plane relative to the first horizontal arm 23; and a vertical arm 25, which is arranged in the second horizontal arm 24 and is configured to be able to move relative to the second horizontal arm 24 in a vertical direction.

[0050] Although the labeling device of the present invention receives regularly placed shoe tongues, there are still slight angle differences between the shoe tongues placed one by one, that is, they are roughly aligned, but there will be slight deflection. Therefore, the visual recognition unit 13 is necessary. It can identify the position and angle of the shoe tongue, so as to control the downstream label picking and placing unit 14 to make a small range of position and angle adjustments, so that the label is accurately aligned with the shoe tongue.

[0051] In addition, the electronic control unit 17 is electrically connected to the conveyor 12, the visual recognition unit 13, the label supply machine 15, the label picking and placing unit 14, the bonding machine 16, the tongue picking and placing unit 18 and the tongue supply unit 19, respectively, for providing them with power and control signals.

[0052] The utility model provides an automatic shoe tongue labeling device with a shoe tongue supply unit, which includes a shoe tongue supply unit. The shoe tongue supply unit can be used to regularly store and supply the shoe tongue, that is, the shoe tongue can be stored in the same orientation. In this way, when the shoe tongue is obtained from the shoe tongue supply unit 19 by the shoe tongue pick-and-place unit and the shoe tongue 30 is placed on the conveyor 12, the shoe tongue is kept in basically the same orientation and is no longer messy. Therefore, when the label picking and placing unit places the label after obtaining the label, it is no longer necessary to move and rotate significantly to match the position and angle of the shoe tongue. The automatic shoe tongue labeling device with a shoe tongue supply unit of the utility model can improve the efficiency of shoe tongue labeling and reduce the workload of the label picking and placing unit. The label picking and placing unit no longer requires a complex structure, so the manufacturing cost and subsequent maintenance cost are low.
