Description

Technical Field

[0001] This invention relates to the field of marking machine technology, specifically to a sorting and marking machine with a classification function. Background Technology

[0002] Label printing machines are ideal for labeling cardboard packaging lines in the food, pharmaceutical, cosmetic, logistics, and other light industries. They provide an effective tool for logistics monitoring applications in various industries. The function is to automatically peel off and paste labels printed in real time onto the surface of the object to be labeled. The label is transferred and applied by the labeling arm, completing a labeling process in five stages: label dispensing, adsorption, extension, pressing, and retraction. The items are scanned by a laser scanner to scan their barcodes, and different items are sent to specific sorting lanes to complete the sorting of the items.

[0003] Labeling machines typically consist of a chassis, a conveyor belt, and a labeler. The conveyor belt transports items, and the labeler applies labels to them. However, when the adhesive tape on cardboard boxes is uneven or when bags have wrinkles, the labels are applied unevenly. Uneven label application can cause errors in subsequent barcode scanning and label recognition, making it difficult to identify the labels. This necessitates manual smoothing or re-adhesion of the labels, which is tedious and increases labor intensity. Therefore, we propose a sorting and labeling machine with classification capabilities. Summary of the Invention

[0004] The purpose of this invention is to provide a sorting and marking machine with classification function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sorting and labeling machine with classification function, comprising: a chassis, a conveyor belt, and a labeler; the conveyor belt is mounted on the top of the chassis, and the labeler is mounted on the side of the chassis; a first monitor for measuring and monitoring the total length of the items is fixed on the surface of the conveyor belt near the item conveying end, and a second monitor for monitoring the item conveying length is fixed on the surface of the conveyor belt near the labeler end; the second monitor controls the operation of a smoothing mechanism through a controller, and the smoothing mechanism is located at the bottom of the labeler.

[0006] The smoothing mechanism includes a smoothing plate for smoothing wrinkles on the surface of an item. A guide plate is fixed to the end face of the smoothing plate near the item conveying end. The two sets of guide plates are symmetrically arranged in a "V" shape.

[0007] The bottom of the guide plate is embedded with a rotating bead, and the bottom of the bead is in contact with the surface of the object.

[0008] The top of the flat plate is fixedly connected to the connecting plate by a connecting rod. A fixing block is fixed to the side wall of the connecting plate, and a sliding rod is fixed to the top of the fixing block. The top of the sliding rod is slidably connected to the movable seat.

[0009] A slider is fixed to the top of the slide rod, and a groove that mates with the slider is opened inside the movable seat.

[0010] The movable base has an insertion hole at one end near the connecting plate one, and the insertion hole is threaded with a double-ended screw. The two ends of the double-ended screw are movably connected to the surface of the fixed plate. The side wall of the fixed plate is fixedly connected to the connecting plate two through the connecting rod two. The top of the connecting plate two is fixed to the bottom of the labeler.

[0011] One end of the bidirectional screw passes through the fixed plate and is fixedly connected to the output shaft of the motor, and the outer wall of the motor is fixedly connected to the surface of the fixed plate.

[0012] A limit rod is fixed to the side wall of the movable seat, and the end of the limit rod away from the movable seat is inserted into the interior of the connecting plate 2. The interior of the connecting plate 2 has a through hole that cooperates with the limit rod.

[0013] The sliding rod is fitted inside the limiting plate. The limiting plate has a limiting groove that slides with the sliding rod. One end of the top of the limiting groove is fixed with a fixing rod, and the top of the fixing rod is fixed to the bottom of the labeler. The other end of the top of the limiting groove is fixed with a fixing rod, and the top of the fixing rod is fixed with a fixing block, which is fixed to the bottom of the labeler.

[0014] The present invention has at least the following beneficial effects:

[0015] By measuring the total length of the item using monitor 1, and when monitor 2 detects that the item has passed one-third of its length, the smoothing mechanism, through the combined monitoring of monitor 1 and monitor 2, smooths out the wrinkles in the middle of the item's surface. This controls the smoothing mechanism to start working, indirectly achieving the synchronous oblique unfolding of the smoothing plate and guide plate. The oblique unfolding and movement of the smoothing plate and guide plate smooths out the wrinkles on the item's surface, making the surface smoother. This facilitates the labeler to apply the label to the item's surface more evenly, making subsequent barcode scanning and item sorting easier. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-8This invention provides a technical solution: a sorting and labeling machine with classification function, including a chassis 1, a conveyor belt 21, and a labeler 22. The conveyor belt 21 is mounted on the top of the chassis 1, and the labeler 22 is mounted on the side of the chassis 1. A first monitor 31 for measuring and monitoring the total length of the items is fixed on the surface of the conveyor belt 21 near the item conveying end. A second monitor 32 for monitoring the item conveying length is fixed on the surface of the conveyor belt 21 near the labeler 22. The second monitor 32 controls the operation of a smoothing mechanism through a controller. The smoothing mechanism is located at the bottom of the labeler 22. Items are conveyed by the conveyor belt 21, and the labeler 22 affixes labels to the surface of the items. When an item passes the monitor... At time 31, monitor 31 begins to monitor the length of the item. When the item is removed from monitor 31, the length monitoring by monitor 31 ends, thus achieving the monitoring of the total length of the item. The calculator calculates one-third of the item's length. When monitor 32 detects that the item has moved one-third of the way, it transmits the signal to controller 1. Controller 1 controls the conveyor belt 21 to stop conveying, and at the same time, controls the smoothing mechanism to start working and controls the motor 52 to start working. The middle part of the item is at the bottom of the labeling plate of labeler 22, so that the label is affixed to the middle part of the item's surface, which is conducive to the label being identified and scanned by the barcode scanner in the subsequent sorting operation.

[0028] The smoothing mechanism includes a smoothing plate 33 for smoothing wrinkles on the surface of an item. A guide plate 34 is fixed to the end face of the smoothing plate 33 near the item conveying end. The two sets of guide plates 34 are symmetrically arranged in a "V" shape. When the guide plate 34 unfolds with the smoothing plate 33, the guide plate 34 smooths the two sides of the item surface in advance. Then the smoothing plate 33 smooths the item surface to both sides, thereby pushing the wrinkles on the item surface to make the item surface smoother, thus making the label application smoother.

[0029] The lower end of the guide plate 34 is embedded with a rotating bead, and the bottom of the rotating bead is in contact with the surface of the item. By setting the rotating bead at the lower end of the guide plate 34, when the guide plate 34 is leveled on the surface of the item, the rotating bead slides on the surface of the item. The bottom of the guide plate 34 on the side away from the flat plate 33 is set to be arc-shaped. When the item comes into contact with the guide plate 34, the arc-shaped design and the rotating bead design can guide the contact with the surface of the item, avoiding the flat plate 33 directly contacting the item and pushing the item to move, thereby maintaining the stability of the item on the surface of the conveyor belt 21.

[0030] The top of the flat plate 33 is fixedly connected to the connecting plate 36 via a connecting rod 35. A fixing block 37 is fixed to the side wall of the connecting plate 36, and a sliding rod 38 is fixed to the top of the fixing block 37. The top of the sliding rod 38 is slidably connected to the movable seat 39. The flat plate 33 is connected to the sliding rod 38 via the connecting rod 35, the connecting plate 36, and the fixing block 37. The sliding rod 38 is slidably connected to the movable seat 39, which facilitates the movable seat 39 to indirectly drive the flat plate 33 to move synchronously, thereby realizing the linkage and cooperation between the movable seat 39 and the flat plate 33.

[0031] A slider 55 is fixed to the top of the slide rod 38, and a groove 56 that mates with the slider 55 is provided inside the movable seat 39. Through the design of the slider 55 and the groove 56, the slide rod 38 can slide at the bottom of the movable seat 39, which limits the sliding of the slide rod 38 at the bottom of the movable seat 39, making the movement of the slide rod 38 more stable and facilitating the symmetrical bidirectional movement of the slide rod 38 driven by the movable seat 39.

[0032] The movable base 39 has an insertion hole 41 at one end near the connecting plate 36, and a double-ended screw 42 is threaded into the insertion hole 41. Both ends of the double-ended screw 42 are movably connected to the surface of the fixed plate 43. The sidewall of the fixed plate 43 is fixedly connected to the connecting plate 53 via a connecting rod 51. The top of the connecting plate 53 is fixed to the bottom of the labeler 22. Rotating the double-ended screw 42, with the cooperation of the threads on the outer wall of the double-ended screw 42 and the threads on the inner wall of the insertion hole 41, allows for the rotation of two... The symmetrical reverse movement of the movable base 39 drives the slide bar 38 to move synchronously, thereby indirectly driving the smoothing plate 33 to move synchronously. Through the rotation of the screw 42, the symmetrical reverse movement of the two smoothing plates 33 is indirectly achieved. The opposing movement of the smoothing plates 33 smooths the surface of the object. The rotation of the screw 42 provides the power source for the movement of the two smoothing plates 33, realizing the linkage between the screw 42 and the smoothing plate 33, making the unfolding of the smoothing plate 33 to both sides more stable.

[0033] One end of the bidirectional screw 42 passes through the fixed plate 43 and is fixedly connected to the output shaft of the motor 52. The outer wall of the motor 52 is fixedly connected to the surface of the fixed plate 43. The motor 52 provides the power source for the rotation of the bidirectional screw 42. The rotation of one set of bidirectional screws 42 can realize the lateral position movement of two sets of moving seats 39. It is not necessary to set two sets of power devices to realize the opposite movement of the two sets of moving seats 39, thus saving the number of power devices and saving costs.

[0034] A limiting rod 54 is fixed to the side wall of the movable seat 39, and the end of the limiting rod 54 away from the movable seat 39 is inserted into the interior of the connecting plate 2 53. The interior of the connecting plate 2 53 is provided with a through hole that cooperates with the limiting rod 54. The limiting rod 54 is restricted by the design of the through hole, thereby restricting the movement of the movable seat 39, so that the movable seat 39 can only move laterally and will not rotate with the rotation of the bidirectional screw 42, thus making the lateral movement of the movable seat 39 more stable.

[0035] The sliding rod 38 is fitted inside the limiting plate 44. The limiting plate 44 has a limiting groove 45 that slides with the sliding rod 38. A fixing rod 46 is fixed to one end of the top of the limiting groove 45, and the top of the fixing rod 46 is fixed to the bottom of the labeler 22. A fixing rod 47 is fixed to the other end of the top of the limiting groove 45, and a fixing block 48 is fixed to the top of the fixing rod 47. The top of the fixing block 48 is fixed to the bottom of the labeler 22. The fixing rod 38 is connected to the limiting plate 44 by the fixing rod 46 and the fixing rod 47. The design of 7 achieves the fixed position of the labeler 22. Through the design of the limiting plate 44 and the limiting groove 45, the movement of the slide rod 38 inside the limiting groove 45 is limited, so that the slide rod 38 moves along the limiting groove 45, thereby indirectly realizing the oblique unfolding of the smoothing plate 33. The oblique movement of the smoothing plate 33 to both sides and the oblique pushing flattening are conducive to pushing the wrinkles backward and pushing the wrinkles to both sides, which is conducive to smoothing the wrinkles on the surface of the item, thus making it easier for the smoothing plate 33 to smooth the surface of the item.

[0036] After monitor 1 31 measures the total length of the item, the signal is transmitted to the calculator, which calculates one-third of the item's length. When monitor 2 32 detects that the item has passed one-third of its length, it transmits the signal to controller 1. Controller 1 controls the conveyor belt 21 to stop working, and simultaneously controls motor 52 to start working. Motor 52 drives the bidirectional screw 42 to rotate synchronously. The rotation of the bidirectional screw 42 causes the moving seat 39 to move symmetrically laterally. The moving seat 39 drives the sliding rod 38 to move synchronously and symmetrically laterally. Guided by the limiting groove 45, the sliding rod 38 moves obliquely. The slide bar 38 drives the smoothing plate 33 to unfold obliquely in sync via the fixing block 37, connecting plate 36, and connecting rod 35. The smoothing plate 33 drives the guide plate 34 to unfold in sync. The unfolding and movement of the smoothing plate 33 and the guide plate 34 realizes the smoothing operation of the wrinkles on the surface of the item. The middle part of the item is located at the bottom of the labeling plate of the labeler 22, which is conducive to the labeler 22 to affix the label to the middle part of the surface of the item. At the same time, the smoothing mechanism is located in the middle position of the surface of the item, which is convenient to push the middle part of the surface of the item and smooth the wrinkles in the middle of the surface of the item, avoiding the smoothing mechanism pushing the corners of the item.

[0037] According to the above embodiments, Embodiment Two

[0038] A control switch 57 is fixed to the surface of the fixed plate 43 near the bidirectional screw 42. The output of the control switch 57 is electrically connected to the input of the motor 52 via a wire. Controller 1 controls the motor 52 to work, and the motor 52 drives the bidirectional screw 42 to rotate synchronously, realizing the rotation operation of the bidirectional screw 42. When the moving seat 39 moves symmetrically in the opposite direction, the smoothing plate 33 smooths the surface of the object. The moving seat 39 moves towards the fixed plate 43 until it presses against the control switch 57. The control switch 57 transmits a signal to controller 2, and the motor 52 of controller 2 stops working, causing the bidirectional screw 42 to stop rotating. At the same time, controller 2... The control signal is transmitted to the labeler 22, and the labeler 22 starts working. The controller 2 transmits the signal to the power mechanism of the conveyor belt 21, and the conveyor belt 21 starts working, so that the conveyor belt 21 works in coordination with the labeler 22. The design of the moving seat 39 moving to abut the control switch 57 connects the smoothing mechanism with the operation of the labeler 22. After the smoothing mechanism finishes smoothing the surface of the item, it transmits the signal to the labeler 22, so that the labeler 22 starts working. The running time of the smoothing mechanism and the labeler 22 are coordinated so that the labeling operation is performed immediately after the smoothing operation of the smoothing mechanism finishes smoothing the surface of the item, so that the efficiency of the machine labeling operation is better.

[0039] According to the above embodiments, in Embodiment 3,

[0040] The lower end of the flat surface plate 33 has a storage cavity 61, and a spring 62 is fixed to the inner wall of the storage cavity 61. A brush plate 63 is fixed to the bottom of the spring 62, and the bottom of the brush plate 63 protrudes from the bottom of the flat surface plate 33. When the bottom of the brush plate 63 is pushed by a hard object, the brush plate 63 is squeezed into the storage cavity 61, and the spring 62 is compressed and stores force, preventing the brush plate 63 from directly contacting the hard object and causing wear, thus increasing the service life of the brush plate 63. Before the labeling process, if dust or debris accumulates on the surface of the item, the adhesive on the label will stick to the dust or debris when the label is applied. Dust and debris can easily cause the adhesive to lose its stickiness. If the adhesive on the back of the label loses its stickiness, the label will not adhere firmly to the surface of the item and will easily peel off. Through the smoothing mechanism mentioned above, while smoothing the surface of the item, the smoothing plate 33 drives the brush plate 63 to move on the surface of the item. 63 can brush away the dust or debris on the surface of the item, preventing dust or debris from accumulating on the position to be labeled and affecting the label's adhesion. This makes it easier for the label to adhere to the surface of the item and will not cause poor adhesion due to dust, resulting in better label adhesion.
