Description

Technical Field

[0001] This utility model relates to the field of integrated weighing, labeling, and barcode scanning machines, and in particular to a label supply mechanism. Background Technology

[0002] Labeling is a common practice in industrial production and commodity distribution. Whether used in the manufacturing process to label product information, specifications, production dates, etc., or in logistics and warehousing management to classify and identify goods, labels play a vital role. Label supply organizations are key equipment for achieving efficient labeling.

[0003] The label supply mechanism mainly consists of a label feeding mechanism and a label tapping device, with the label feeding mechanism and the label tapping device being the main components. The label feeding mechanism consists of a label roll, a drive unit, and a label peeling device.

[0004] A common label supply mechanism is installed on a weighing, labeling, and barcode scanning machine. In use, the label roll is first mounted on the label feeding mechanism. A drive unit rotates the label roll, and a label peeling device separates the label from the backing paper, placing the label in a ready-to-apply state. The label applicator includes a vision positioning system, a robotic arm, or a tapping device. While the label feeding mechanism prepares the labels, the label applicator uses a vision positioning system to identify and locate the product or labeling location, determining the precise placement of the label. When the product arrives at the designated labeling location, the label feeding mechanism, according to instructions from the control system, accurately delivers the label to the label applicator's effective range. Simultaneously, based on information obtained from the vision positioning system, the label applicator precisely taps or affixes the label to the product.

[0005] However, during product transport, the product is typically conveyed from a belt scale to the weighing, labeling, and barcode scanning integrated machine. An unavoidable gap exists at the connection point, which can easily cause product fluctuations and sometimes tilting. This affects the accuracy of the vision positioning system, potentially leading to incomplete label application. Since labels are highly adhesive, they can easily stick to the device, affecting subsequent labeling work. If a label sticks to the labeling device, it can also disrupt the normal supply of subsequent labels, impacting the labeling effect.

[0006] Therefore, a label supply organization is proposed to solve the above problems. Utility Model Content

A positioning mechanism is provided on the upper surface of the machine body 1. The positioning mechanism includes a guide component and a limiting component. The guide component includes a mounting block 31. The mounting block 31 is fixed to the right surface of the machine body 1 with bolts. A sleeve 32 is fixedly connected to the left surface of the mounting block 31. The sleeve 32 is sealed inside and the internal cavity is filled with antifreeze. A sliding rod 33 is connected to the left surface of the sleeve 32 through and piston-connected. The outer wall of the sliding rod 33 is made of rubber and the inner wall is made of hard material to ensure that the sliding rod 33 will not deform. The outer wall of the sliding rod 33 and the sleeve 32 fit tightly. A movable guide plate 34 is fixedly connected to the left surface of the sliding rod 33. A fixed guide plate 35 is fixedly connected to the left end of the upper surface of the machine body 1. The movable guide plate 34 and the fixed guide plate 35 are used to provide guidance for the outer casing.

[0034] Reference Figure 2 - Figure 4The limiting component includes a sealing gasket 41. The surface of the sealing gasket 41 is made of rubber, and the interior is made of hard material to ensure stability. A round tube 42 is fixedly connected through the right surface of the sealing gasket 41. A one-way valve 43 is provided in the middle section of the round tube 42. The one-way valve 43 is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. A through groove 401 is opened at the right end of the front surface of the slide rod 33. A round hole 402 is opened on the left surface of the sealing gasket 41. An annular groove 403 is opened on the left surface of the sealing gasket 41. A connecting block 45 is elastically connected to the inner wall of the slide rod 33 through a compression spring 46. A pull rod 47 is fixedly connected to the left surface of the connecting block 45. The connecting block 45, the pull rod 47 and the lever 48 will move synchronously. A lever 48 is fixedly connected to the left end of the upper surface of the pull rod 47. A rubber ring 44 is fixedly connected to the right surface of the connecting block 45. The annular groove 403 and the rubber ring 44 fit together.

[0035] Reference Figure 2 - Figure 4 The scanning weighing machine 21 is located on the left end of the upper surface of the machine body 1. The scanning weighing machine 21 can scan the labeling status and measure the weight of the outer box. The left surface of the mounting block 31 is fixedly connected to the top of the right surface of the machine body 1. The rear surfaces of the movable guide plate 34 and the fixed guide plate 35 are both fixedly connected to the guide blocks 36. The guide blocks 36 are set in an inclined shape. There are multiple sets of guide blocks 36, which are evenly distributed at the front and rear ends of the movable guide plate 34 and the fixed guide plate 35, and the end away from the movable guide plate 34 and the fixed guide plate 35 opens to the left and right sides.

[0036] Reference Figure 2 - Figure 4 The sealing gasket 41 is piston-connected to the inner wall of the sleeve 32 to maintain a seal. The left surface of the sealing gasket 41 is fixedly connected to the right surface of the slide rod 33, and the two move synchronously. One end of the compression spring 46 is fixedly connected to the left surface of the connecting block 45, and the other end of the compression spring 46 is fixedly connected to the inner wall on the left side of the slide rod 33. When the connecting block 45 moves to the left, it will squeeze the compression spring 46 to generate a reaction force. The connecting block 45 passes through and slides on the right surface of the slide rod 33, and moves laterally. The rubber ring 44 is inserted into the inner wall of the annular groove 403 to block the round hole 402 and maintain a seal. The pull rod 47 passes through and slides on the upper surface of the slide rod 33. The pull rod 47 is set in an L shape.

[0037] Working principle: When using this device, first place the outer box on the belt scale 23 for weighing. Then, adjust the position of the movable guide plate 34 according to the width of the outer box to change the distance between the movable guide plate 34 and the fixed guide plate 35. If it is necessary to adjust the movable guide plate 34 to the left, simply move the movable guide plate 34 to the left. When the movable guide plate 34 moves to the left, the slide rod 33 and the sealing gasket 41 will be pulled to the left, and the antifreeze on the left side of the sealing gasket 41 will be squeezed. The antifreeze will flow through the round pipe 42 and the one-way valve 43 to the right side of the sealing gasket 41. Stop moving when it reaches the appropriate position.

[0038] If the movable guide plate 34 needs to be moved to the right, the left-moving lever 48 drives the pull rod 47, connecting block 45 and rubber ring 44 to move to the left. The rubber ring 44, moving to the left, will disengage from the annular groove 403, allowing the through groove 401 and the round hole 402 to connect. The left-moving connecting block 45 will compress the compression spring 46 to generate a reaction force, which will then pull the movable guide plate 34 to the right. The movable guide plate 34 will drive the slide rod 33 and the sealing gasket 41 to move to the right. During the movement, the antifreeze on the right side of the sealing gasket 41 will be squeezed, and the antifreeze will flow through the round hole 402 and the through groove 401 to the left side of the sealing gasket 41. When the appropriate position is reached, the movement can be stopped. When the lever 48 is released, the reaction force of the compression spring 46 will push the rubber ring 44 and the annular groove 403 to re-adhere.

[0039] Since the movable guide plate 34 needs to be released from its limit before moving to the right, the distance between the movable guide plate 34 and the fixed guide plate 35 will not increase further when squeezed by the outer box.

[0040] Then, the belt weigher 23, the scanning weighing machine 21, the label applicator 22, and the machine body 1 are started to apply labels. The outer box will first move steadily along the trajectory of the guide block 36 to the space between the fixed guide plate 35 and the guide block 36. When it passes the label applicator 22, the label applicator 22 will affix the label to the outer box. When it passes the scanning weighing machine 21, the weight and label affixing status will be recorded.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
