Description

Technical Field

[0001] This utility model relates to the field of label attaching equipment technology, and in particular to an automated label attaching machine. Background Technology

[0002] Label attaching machines are specialized sewing equipment commonly used in modern industry. They are used to attach socks, gloves, and other products together or to attach labels (which are rigid paper pieces) indicating the material, size, and price of the products. Products sewn together by a label attaching machine are not permanently fixed but can be quickly removed during use.

[0003] In current technology, when using a label attaching machine to attach tags to socks, the socks with tags already pre-attached (simply for connection) are typically placed manually onto the sewing machine head for sewing. During sewing, the socks must be manually pressed down, aligned with the sewing position, and ensured to be straight, making the operation rather cumbersome. Furthermore, after labeling one pair of socks, the worker needs to remove them and retrieve another pair from the material box for labeling, which is also time-consuming. Moreover, after prolonged work, workers are prone to fatigue, resulting in low efficiency and wasted time and effort, necessitating improvements. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automated label attaching machine.

[0013] Preferably, the automated labeling machine further includes:

[0014] The first proximity switch is located above the feeding rack or the frame to sense whether a product to be labeled has entered the guide channel and transmits the signal to the central control mechanism, which controls the drive device to work.

[0015] The second proximity switch is located upstream and below the sewing machine head. It is used to sense whether a product to be labeled is about to enter the work position of the sewing machine head and transmit the signal to the central control mechanism, which controls the sewing machine head to work.

[0016] Preferably, the driving device includes:

[0017] The first motor is mounted on the frame;

[0018] The first shaft is fixed to the first shaft;

[0025] The fixing seat is fixed on the guide belt frame;

[0026] The fourth shaft is mounted on the fixed base, and the first synchronous pulley is fixed on the fourth shaft;

[0027] The third synchronous belt pulley assembly is disposed between the third shaft and the fourth shaft;

[0028] The second synchronous pulley is mounted on the guide belt frame, and a synchronous belt is provided between the first synchronous pulley and the second synchronous pulley.

[0029] Preferably, the conveyor belt assembly includes a first conveyor belt and a second conveyor belt, wherein the first conveyor belt is arranged in front of the second conveyor belt, and the rollers of both the first conveyor belt and the second conveyor belt are fixed on the first shaft.

[0030] Preferably, the guide belt frame includes:

[0031] The framed main body extends along the first direction;

[0032] A plurality of first guide pulleys are fixed at intervals along a first direction at the front end of the belt frame body and are used to cooperate in installing the first guide belt;

[0033] A plurality of second guide pulleys are fixed at intervals along the first direction at the rear end of the belt frame body and are used to cooperate in installing the second guide belt;

[0034] Both the first guide belt and the second guide belt bypass the second synchronous pulley, and the first guide belt and the first conveyor belt cooperate to transport the product, while the second guide belt and the second conveyor belt cooperate to transport the tag.

[0041] Compared with the prior art, this utility model has the following beneficial effects:

[0042] 1. The worker only needs to place the product to be labeled on the feeding rack at the feeding end of the guide channel. When the first proximity switch senses that a product is placed at this position, the PLC controls the drive device to work, so that the conveyor belt and the guide belt work together to transport the product to be labeled along the first direction. When the second proximity switch senses that the product to be labeled is about to enter the sewing machine head, the PLC controls the sewing machine head to work after a certain period of time (the product to be labeled is placed below the sewing machine head). The equipment runs stably, saves energy, and can complete the automated conveying and sewing of the product to be labeled.

[0043] 2. Multiple sets of synchronous pulley assemblies, shafts, and gears are used in conjunction to drive the guide belt, which can more accurately control the transport speed of the guide belt and ensure that the guide belt and the conveyor belt work synchronously, thus better completing the stable transport of products to be labeled.

[0044] 3. By setting an adjustment device, the height of the guide channel can be adaptively adjusted according to the thickness of the socks. Without affecting the conveying of the product to be labeled, it can be pressed down and positioned. When the product to be labeled is conveyed to the sewing machine head, there will be no positional deviation, thus enabling more accurate labeling. Attached Figure Description

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0057] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0058] Detailed implementation plan: See below Figures 1-7 This utility model is an automated label attaching machine, including a frame 1, a sewing machine head 8 mounted on the frame 1, and further including:

[0059] The feeding rack 2 is located on one side of the frame 1;

[0060] The drive unit 3 is mounted on the frame 1 and is used to work in conjunction with the drive conveyor belt assembly 4 and the transmission unit 6.

[0061] Positioning device 7 is installed on frame 1;

[0062] The guide belt frame 5 is linked to the adjustment device 7 and is arranged above the conveyor belt assembly 4. A material guide channel is formed between the guide belt frame 5 and the conveyor belt assembly 4 for the products to be labeled to pass through. The guide belt frame 5 is provided with at least one guide belt, and the conveyor belt assembly 4 is provided with at least one conveyor belt.

[0063] Transmission device 6 is located between drive device 3 and guide frame, and is used to cooperate in driving the guide belt.

[0064] The guide belt and the conveyor belt work together to drive the product to be labeled to move horizontally in the first direction. The sewing machine head 8 is arranged at the end of the conveyor belt of the product to be labeled, and is used to sew and fix the label to the product.

[0065] As a preferred embodiment of this invention, the automated labeling machine further includes:

[0066] The first proximity switch 9 is located above the feeding rack 2 or the frame 1. It is used to sense whether a product to be labeled has entered the guiding channel and transmit the signal to the central control mechanism 12. The central control mechanism 12 controls the drive device 3 to work.

[0067] The second proximity switch 11 is located upstream and below the sewing machine head 8. It is used to sense whether a product to be labeled is about to enter the work station of the sewing machine head 8 and transmit the signal to the central control mechanism 12. The central control mechanism 12 controls the sewing machine head 8 to work.

[0068] In this embodiment, the central control mechanism 12 is a PLC. The feeding rack 2 holds many socks with pre-assembled labels, i.e., products to be labeled. When it is necessary to complete the labeling process, please refer to... Figure 1 Workers place the products to be labeled at the feed end of the guide channel. When the first proximity switch 9 senses that the products to be labeled are placed at that position, it will transmit a signal to the PLC. The PLC controls the drive device 3 to work, so that the conveyor belt and the guide belt work together to transport the products to be labeled along the first direction.

[0069] Before the product to be labeled enters the sewing machine head 8, it passes through the second proximity switch 11. When the second proximity switch 11 senses the passing of the product, it transmits a signal to the PLC. The PLC then controls the sewing machine head 8 to start working after a certain period of time (the time is adjusted according to the conveyor belt and guide belt speed). In this way, when the product to be labeled enters the work position directly below the sewing machine head 8, the sewing and fixing of the label can be completed.

[0070] Then, please see Figures 3-5 As can be seen, in this embodiment, the driving device 3 includes:

[0071] The first motor 31 is mounted on the frame 1;

[0072] The first shaft 33, the rollers on the conveyor belt assembly 4 are fixed on the first shaft 33;

[0073] The first synchronous belt pulley assembly 32 is disposed between the first motor 31 and the first shaft 33.

[0074] Next, please refer to Figure 4 and Figure 5 As can be seen, in this embodiment, the transmission device 6 includes:

[0075] Mounting bracket 63 is mounted on rack 1;

[0076] The second shaft 62 is mounted on the mounting base 63, and the drive gear 64 is fixed on the second shaft 62.

[0077] The second synchronous belt pulley assembly 61 is disposed between the first shaft 33 and the second shaft 62;

[0078] The third shaft 66 is mounted on the mounting base 63. A driven gear 65 is fixed on the third shaft 66, and the driven gear 65 meshes with the driving gear 64.

[0079] The fixing seat 69 is fixed on the guide belt frame 5;

[0080] The fourth shaft 68 is mounted on the fixed seat 69, and the first synchronous pulley 610 is fixed on the fourth shaft 68.

[0081] The third synchronous belt pulley assembly 67 is disposed between the third shaft 66 and the fourth shaft 68;

[0082] The second synchronous pulley 612 is mounted on the guide belt frame 5, and a synchronous belt 611 is provided between the first synchronous pulley 610 and the second synchronous pulley 612.

[0083] Note that in this embodiment, the first synchronous pulley assembly 32, the second synchronous pulley assembly 61, and the third synchronous pulley assembly 67 all adopt the structure of synchronous pulley + synchronous belt 611, which is the prior art and will not be explained in detail here.

[0084] Next, in this embodiment, the conveyor belt assembly 4 includes a first conveyor belt 41 and a second conveyor belt 42, wherein the first conveyor belt 41 is arranged in front of the second conveyor belt 42, and the rollers of the first conveyor belt 41 and the second conveyor belt 42 are both fixed on the first shaft 33.

[0085] Working principle of drive device 3 driving conveyor belt assembly 4:

[0086] The first motor 31 operates and drives the first shaft 33 to rotate through the first synchronous belt pulley assembly 32. Since the rollers of the first conveyor belt 41 and the second conveyor belt 42 are both fixed on the first shaft 33, the first conveyor belt 41 and the second conveyor belt 42 can be driven to run synchronously.

[0087] The working principle of the drive unit 3 driving the guide belt frame 5 through the transmission device 6:

[0088] Since the second synchronous belt pulley assembly 61 is located between the first shaft 33 and the second shaft 62, the rotation of the first shaft 33 can drive the rotation of the second shaft 62. Since both the second shaft 62 and the third shaft 66 are mounted on the mounting base 63 via bearings, the second shaft 62 is equipped with a driving gear 64, and the third shaft 66 is equipped with a driven gear 65. The driving gear 64 and the driven gear 65 mesh with each other, and the rotation of the second shaft 62 can drive the rotation of the third shaft 66 (the driving gear 64 is a large gear, the driven gear 65 is a small gear, and the third shaft...). The rotational speed of rod 66 is greater than that of the second shaft 62; since the fourth shaft 68 is mounted on the fixed base 69, the fourth shaft 68 is provided with a first synchronous pulley 610, and a third synchronous belt pulley assembly 67 is provided between the fourth shaft 68 and the third shaft 66, the rotation of the third shaft 66 can drive the fourth shaft 68 and the first synchronous pulley 610 fixed on the fourth shaft 68 to rotate; since a synchronous belt 611 is provided between the first synchronous pulley 610 and the second synchronous pulley, the rotation of the first synchronous pulley 610 can drive the second synchronous pulley 612 to rotate.

[0089] Here, by setting the driving gear 64 and the driven gear 65, the transmission assembly acts like a gearbox, increasing the rotational speed of the second synchronous pulley 612. This ensures that the translational speed of the guide belt and the conveyor belt remain consistent (the diameter of the second synchronous pulley 612 is smaller than the diameter of the drum). Furthermore, the use of multiple sets of synchronous pulley assemblies, shafts, and gears in coordination to drive the guide belt allows for more precise control of its transport speed and ensures that the guide belt and conveyor belt work synchronously, resulting in more stable transport of the products to be labeled.

[0090] Next, please refer to Figure 6 As can be seen, in this embodiment, the guide belt frame 5 includes:

[0091] The frame body 51 extends along the first direction;

[0092] A plurality of first guide pulleys 52 are fixed at intervals along a first direction at the front end of the belt frame body 51 and are used to cooperate in installing the first guide belt 53;

[0093] A plurality of second guide pulleys 54 are fixed at intervals along the first direction at the rear end of the belt frame body 51 and are used to cooperate in the installation of the second guide belt 55;

[0094] The first guide belt 53 and the second guide belt 55 both bypass the second synchronous pulley 612. The first guide belt 53 and the first conveyor belt 41 cooperate to transport products, and the second guide belt 55 and the second conveyor belt 42 cooperate to transport labels.

[0095] Here, the arrangement of the first guide pulley 52 and the second guide pulley 54 allows for more stable cyclic rotation of the first guide belt 53 and the second guide belt 55. Furthermore, the two guide belts ensure smoother transport of the product and label.

[0096] Please see Figure 7 As can be seen, in this embodiment, the adjustment device 7 is disposed between the transmission device 6 and the sewing machine head 8, and includes:

[0097] Stand 71 is mounted on frame 1;

[0098] The support frame 72 is fixed on the stand 71, and the support frame 72 is provided with at least one vertically arranged optical axis 73;

[0099] A socket block 74 is fitted onto the optical axis 73. At least one spring is provided between the socket block 74 and the bottom of the support frame 72. The spring is fitted onto the optical axis 73.

[0100] The pressing member 75 is fixed on the sleeve block 74, and the guide belt frame 5 is fixed below the pressing member 75.

[0101] The working principle of the adjustment device 7 is as follows: After the product to be labeled enters the guide channel, if the thickness of the product increases, it will press the lower pressure member 75 upward. Since the lower pressure member 75 is fixed on the sleeve block 74, it will drive the sleeve block 74 to move upward. If the thickness of the product to be labeled decreases, the lower pressure member 75 will press downward due to gravity. The spring setting ensures that the lower pressure member 75 always maintains pressure on the product to be labeled, and allows the height of the lower pressure member 75 to be adaptively adjusted within a certain range.

[0102] More specifically, in this embodiment, the automated labeling machine also includes a translation drive assembly 10, which includes a second motor 101 mounted on the frame 1 and a connecting crossbar 102 linked to the second motor 101. A second proximity switch 11 is mounted on the connecting crossbar 102 and is located on the side of the material guide channel.

[0103] Here, the second motor 101 is a linear motor, which can drive the connecting crossbar 102 to move back and forth, thereby adjusting the front and rear position of the second proximity switch 11. (The sizes of the tags vary, so the rear end positions of different tags may differ.)

[0104] The above description of an automated labeling machine of this utility model is only a preferred embodiment of this utility model and does not limit the patent scope of this utility model. All equivalent structural transformations made under the inventive concept of this utility model using the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
