Description

Technical Field

[0001] The present disclosure relates to the technical field of corner labeling, and in particular to a corner label reinforcement device and a corner labeling machine. Background Art

[0002] Generally speaking, a corner mark refers to a mark or logo made on the corner of an object. Due to its advantages such as improving label recognition, enhancing visual effects, and protecting vulnerable parts, corner marks are widely used in various fields.

[0003] For example, in the pharmaceutical industry, corner labels are usually affixed to the corners of cartons. Corner labels not only provide additional protection and support to protect the safety and integrity of drugs, but also serve as a carrier of drug information, facilitating the identification, tracking and management of drugs.

[0004] However, in actual application, since the surface of the carton is relatively rough, when the corner label is placed on the corner label of the carton, the connection strength between the corner label and the carton is weak, resulting in the corner label easily falling off during use.

[0005] In order to improve the connection strength between the corner label and the carton, some scholars believe that a label pressing device can be added to the corner labeling machine. For example, Chinese document No. CN 210971858 U discloses a label pressing device that adds two label pressing rollers, a side stop device and a drive device to the conveyor belt to achieve compaction and reinforcement of the label on the can body.

[0006] However, from the above pressure standard equipment Figure 1 and Figure 2 It can be seen that the two label pressing rollers are set with a large gap between them, resulting in a large compaction blind area when the two label pressing rollers compact the corner label, causing the connection strength between the corner label and the carton to be weak, and there is still a probability that the corner label will fall off easily. Utility Model Content

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a corner label reinforcement device and a corner labeling machine that can effectively reduce the compaction blind area of the corner label and improve the connection strength between the corner label and the carton.

[0008] The purpose of this disclosure is achieved through the following technical solutions:

[0009] A corner label reinforcement device includes a label pressing assembly and a side stop assembly. The label pressing assembly and the side stop assembly are sequentially arranged at intervals along the conveying assembly of the corner labeling machine. The side stop assembly is used to limit the movement of cartons in the conveying assembly.

[0010] The marking assembly includes a mounting frame, a movable frame, a first marking roller, a second marking roller and an elastic member. The mounting frame is arranged on one side of the conveying assembly, and the movable frame is movably and tiltedly arranged on the mounting frame. The first marking roller and the second marking roller are respectively rotatably arranged on the movable frame. The first marking roller is elastically connected to the second marking roller through the elastic member, and the first marking roller and the second marking roller abut against each other to form a movable abutment portion, and the movable abutment portion is arranged corresponding to the corner mark of the carton.

[0011] In one embodiment, the intersection line of the movable abutting portion coincides with the corner line of the corner mark.

[0012] In one embodiment, the sum of the rotational contact area between the first marking roller and the corner mark and the rotational contact area between the second marking roller and the corner mark is greater than or equal to the total area of the corner mark.

[0013] In one embodiment, the baffle of the side baffle assembly is an L-shaped baffle, and a blocking cavity is formed on a side of the L-shaped baffle facing the label pressing assembly, and the blocking cavity is used to limit the movement of the carton.

[0014] In one embodiment, the blocking cavity is a right-angle blocking cavity.

[0015] In one embodiment, the first marking roller includes a first mounting seat and a first flexible roller. The first mounting seat is detachably connected to the movable frame, and the first flexible roller is rotatably disposed on the first mounting seat.

[0016] In one embodiment, the second marking roller includes a second mounting seat and a second flexible roller, the second mounting seat is detachably connected to the movable frame, and the second flexible roller is rotatably disposed on the second mounting seat.

[0017] In one embodiment, the first end of the elastic member is connected to the first mounting seat, and the second end of the elastic member is connected to the second mounting seat.

[0018] In one embodiment, the corner mark reinforcement device further includes a first screw, the movable frame is provided with an adjustment slot, the first mounting seat is formed with a first threaded hole, the first screw passes through the adjustment slot and the first threaded hole, and is threadedly connected to the inner wall of the first threaded hole; and / or,

[0019] The first mounting base includes a first base, a first connecting rod and a second connecting rod, wherein the first end of the first connecting rod and the second end of the second connecting rod are rotatably disposed at two ends of the first base, respectively, and the second end of the second connecting rod and the second end of the second connecting rod are rotatably disposed with the first flexible roller respectively; and / or,

[0020] The reinforcement device of the corner mark also includes a first driver and a second driver, the driving end of the first driver is connected to the movable frame, and the first driver is obliquely arranged on the mounting frame; the driving end of the second driver is connected to the L-shaped baffle of the side baffle assembly.

[0021] A corner labeling machine comprises the corner label reinforcement device described in any one of the above embodiments.

[0022] Compared with the prior art, the present disclosure has at least the following advantages:

[0023] Since the movable frame is movably and obliquely arranged on one side of the conveying assembly, the first pressure roller and the second pressure roller arranged on the movable frame can form an angle with the conveying assembly, ensuring that the movable abutment formed subsequently can be set corresponding to the corner mark of the carton; and since the first pressure roller and the second pressure roller abut against each other to form a movable abutment, the gap between the first pressure roller and the second pressure roller is effectively reduced; when in use, the movable frame and the side stop assembly are connected to the external driver, and when the carton with the corner mark just affixed is conveyed to the preset position by the conveying assembly, the movable frame and the side stop assembly can be extended to the carton of the conveying assembly under the action of the external driver, so that the side stop assembly can limit the carton on the conveying assembly, effectively preventing it from moving, and when the movable abutment abuts against the corner mark of the carton, the first pressure roller and the second pressure roller are in contact with the external driver. Under the action of continued driving, the movable abutment part can elastically rotate and stretch when it is blocked by the carton, so that when the movable abutment is in the process of elastically rotating and stretching, the first pressure roller and the second pressure roller can respectively rotate and abut with the corner mark, that is, the first pressure roller and the second pressure roller can simultaneously rotate and abut from the movable abutment part to the two sides of the corner mark, so that the first pressure roller and the second pressure roller can more comprehensively press the corner mark on the carton, effectively reducing the compaction blind area of the corner mark, thereby improving the connection strength between the corner mark and the carton, that is, realizing the reinforcement of the corner mark, thereby reducing the probability of the corner mark falling off, and at the same time, in conjunction with the use of the elastic part, when the external force disappears, such as the blocking force of the carton, the first pressure roller and the second pressure roller will reset under the action of the elastic part, so as to prepare for the next compaction of the corner mark.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0036] See also Figure 1 、 Figure 4 and Figure 5 , a reinforcement device 10 of a corner label of an embodiment includes a pressure label component 100 and a side stop component 200, the pressure label component 100 and the side stop component are sequentially arranged at intervals along the conveying component 20 of the corner labeling machine 1, the side stop component 200 is used to limit the movement of the carton of the conveying component 20, the pressure label component 100 includes a mounting frame 110, a movable frame 120, a first pressure label roller 130, a second pressure label roller 140 and an elastic member 150, the mounting frame 110 is arranged on one side of the conveying component 20, the movable frame 120 is movably and tiltedly arranged on the mounting frame 110, the first pressure label roller 130 and the second pressure label roller 140 are respectively rotatably arranged on the movable frame 120, the first pressure label roller 130 is elastically connected to the second pressure label roller 140 by the elastic member 150, and the first pressure label roller 130 and the second pressure label roller 140 abut against each other to form a movable abutment portion 160, please refer to Figure 6 The movable abutment portion 160 is arranged corresponding to the corner mark of the carton.

[0037] It can be understood that, since the movable frame 120 is movably and obliquely arranged on one side of the conveying assembly 20, the first pressure roller 130 and the second pressure roller 140 arranged on the movable frame 120 can form an angle with the conveying assembly 20, ensuring that the subsequently formed movable abutment portion 160 can be arranged corresponding to the corner mark of the carton; since the conveying assembly 20 is formed with a conveying area, so that the conveying area can convey the carton with the corner mark just affixed, when the carton with the corner mark just affixed is conveyed to the preset position by the conveying assembly 20 The movable frame 120 and the side stop assembly 200 can be extended to the carton of the conveying assembly 20 under the action of the external driver, so that the side stop assembly 200 can limit the carton on the conveying assembly 20, effectively preventing it from moving. In addition, since the first pressure roller 130 and the second pressure roller 140 abut against each other to form a movable abutting portion 160, the gap between the first pressure roller 130 and the second pressure roller 140 is effectively reduced; when the movable abutting portion 160 abuts against the corner mark of the carton, the first pressure roller 130 and the second pressure roller 140 are Under the action of the external driver continuing to drive the roller 130 and the second pressure roller 140, the movable abutment portion 160 can be elastically rotated and stretched when blocked by the carton, so that the first pressure roller 130 and the second pressure roller 140 can respectively rotate and abut against the corner mark during the elastic rotation and stretching process of the movable abutment, that is, the first pressure roller 130 and the second pressure roller 140 can simultaneously rotate and abut from the movable abutment portion 160 to the two sides of the corner mark, so that the first pressure roller 130 and the second pressure roller 140 can respectively rotate and abut against the corner mark. The marking roller 130 and the second marking roller 140 can press the corner label onto the carton more comprehensively, effectively reducing the blind area of the corner label compaction, thereby improving the connection strength between the corner label and the carton, that is, reinforcing the corner label, thereby reducing the probability of the corner label falling off. At the same time, in conjunction with the use of the elastic member 150, when the external force disappears, such as the blocking force of the carton, the first marking roller 130 and the second marking roller 140 will be reset under the action of the elastic member 150, so as to prepare for the next compaction of the corner label.

[0038] In one embodiment, the intersection line of the movable abutment portion 160 coincides with the corner line of the corner mark, ensuring that the compaction starting point of the movable abutment portion 160 and the corner mark is the corner line of the corner mark. In this way, the first pressing roller 130 and the second pressing roller can rotate and abut more comprehensively from the corner line of the corner mark to both sides of the corner mark. On the one hand, the compaction and reinforcement of the corner mark by the first pressing roller 130 and the second pressing roller are more comprehensively achieved. On the other hand, the stability of the rotational abutment between the first pressing roller 130 and the second pressing roller and the corner mark is ensured, effectively avoiding the phenomenon that the carton is easily turned over when the intersection line of the movable abutment portion 160 does not coincide with the corner line of the corner mark.

[0039] In one embodiment, the sum of the rotational contact area between the first marking roller 130 and the corner mark and the rotational contact area between the second marking roller 140 and the corner mark is ≥ the total area of the corner mark, so as to ensure that the first marking roller 130 and the second marking roller 140 can achieve comprehensive compaction and reinforcement of the corner mark, effectively reducing the compaction blind area.

[0040] like Figure 2 and Figure 3 As shown, in one embodiment, the baffle of the side baffle assembly 200 is an L-shaped baffle 210, and a blocking cavity 211 is formed on the side of the L-shaped baffle 210 facing the pressure label assembly 100, and the blocking cavity 211 is used to limit the movement of the carton to ensure that the L-shaped baffle 210 can limit the carton on the conveying assembly 20 under the action of the external driver.

[0041] In one embodiment, the blocking cavity 211 is a right-angle blocking cavity 211, so that the right-angle blocking cavity 211 is adapted to the corner of the carton to achieve better blocking restriction on the carton.

[0042] like Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, the first marking roller 130 includes a first mounting seat 131 and a first flexible roller 132. The first mounting seat 131 is detachably connected to the movable frame 120, which is convenient for the user to disassemble and assemble the first mounting seat 131. The first flexible roller 132 is rotatably set on the first mounting seat 131 to realize the rotational connection of the first flexible roller 132.

[0043] Similarly, in one embodiment, the second marking roller 140 includes a second mounting seat 141 and a second flexible roller 142. The second mounting seat 141 is detachably connected to the movable frame 120, which is convenient for the user to disassemble and assemble the second mounting seat 141. The second flexible roller 142 is rotatably set on the second mounting seat 141 to realize the rotational connection of the second flexible roller 142.

[0044] like Figure 4 and Figure 5 As shown, in one embodiment, the first mounting seat 131 includes a first base 1311, a first connecting rod 1312, and a second connecting rod. The first end of the first connecting rod 1312 and the first end of the second connecting rod are rotatably mounted on opposite ends of the first base 1311, respectively. The second end of the first connecting rod 1312 and the second end of the second connecting rod are rotatably mounted on opposite ends of the first flexible roller 132, respectively, to achieve rotatable mounting of the first flexible roller 132 and the first mounting seat 131. Similarly, the second mounting seat 141 also has a similar structure.

[0045] like Figure 4 and Figure 5 As shown, in one embodiment, the first end of the elastic member 150 is connected to the first mounting seat 131, and the second end of the elastic member 150 is connected to the second mounting seat 141, so as to realize the elastic connection between the first mounting seat 131 and the second mounting seat 141. Specifically, the elastic member 150 is a spring, the first end of the spring is elastically connected to the first connecting rod 1312, and the second end of the spring is elastically connected to the third connecting rod 1411 of the second mounting seat 141.

[0046] In one embodiment, the corner marker reinforcement device 10 further includes a first screw 300. The movable frame 120 defines an adjustment slot 121, and the first mounting seat 131 forms a first threaded hole. The first screw 300 passes through the adjustment slot 121 and the first threaded hole and is threadedly engaged with the inner wall of the first threaded hole, thereby threading the first mounting seat 131 to the movable frame 120. Furthermore, the additional adjustment slot 121 facilitates user adjustment of the position of the first mounting seat 131 on the movable frame 120 to better accommodate the compaction and reinforcement of different corner markers, thereby improving the adaptability of the corner marker reinforcement device 10.

[0047] Similarly, the second mounting seat 141 also has a similar structure. Specifically, the reinforcement device 10 of the corner mark also includes a second screw, and the movable frame 120 is provided with an adjustment slot 121. The second mounting seat 141 forms a second threaded hole, and the second screw passes through the adjustment slot 121 and the second threaded hole, and is threadedly connected to the inner wall of the second threaded hole; the second mounting seat 141 and the movable frame 120 are threadedly connected, which facilitates the user to adjust the position of the second mounting seat 141 on the movable frame 120, ensuring that the user can adjust the first mounting seat 131 or the second mounting seat 141 separately, and can adjust the first mounting seat 131 and the second mounting seat 141 at the same time, thereby improving the user's flexibility in adjusting the pressure mark assembly 100 to better adapt to the compaction and reinforcement of different corner marks.

[0048] In one embodiment, the corner mark reinforcement device 10 further includes a first driver 400 and a second driver 500, wherein the driving end of the first driver 400 is connected to the movable frame 120, and the first driver 400 is tiltedly arranged on the mounting frame 110; the first driver 400 can drive the movable frame 120 to move toward or away from the carton, thereby driving the movable contact portion 160 of the first pressure roller 130 and the second pressure roller 140 to move toward or away from the corner mark of the carton, thereby realizing the first The marking roller 130 and the second marking roller 140 extend or retract; and since the driving end of the second driver 500 is connected to the L-shaped baffle 210 of the side baffle assembly 200, the second driver 500 can drive the L-shaped baffle 210 to move toward or away from the carton, that is, the extension or retraction of the L-shaped baffle 210 is realized; since the L-shaped baffle 210 is formed with a blocking cavity 211 on the side facing the marking assembly 100, the L-shaped baffle 210 can better realize the limiting effect on the carton on the conveying assembly 20.

[0049] In one embodiment, the second driver 500 is vertically arranged on one side of the conveying component 20 to ensure that the L-shaped baffle 210 can reliably translate under the action of the second driver 500 to ensure that the L-shaped baffle 210 can quickly and smoothly limit the carton.

[0050] Working principle: When the carton with the corner mark just affixed is transported to the preset position by the conveying assembly 20, first, the second driver 500 drives the L-shaped baffle 210 to extend, so that the L-shaped baffle 210 can limit the carton on the conveying assembly 20, and then the first driver 400 drives the movable frame 120 to extend, so that the movable abutment 160 abuts against the corner mark of the carton. Due to the obstruction of the carton, the movable abutment 160 can elastically rotate and stretch at the corner mark, so that during the elastic rotation and stretching process of the movable abutment, the first pressure roller 130 and the second pressure roller 140 can simultaneously move away from the movable abutment 160 respectively. The first pressing roller 130 and the second pressing roller 140 rotate and abut against each other on both sides of the corner mark, so that the first pressing roller 130 and the second pressing roller 140 can more comprehensively press the corner mark on the carton during the process of rotating and abutting; when the first pressing roller 130 and the second pressing roller 140 complete the pressing operation, the second driver 500 drives the L-shaped baffle 210 to retract, and due to the disappearance of external force, the first pressing roller 130 and the second pressing roller 140 will be reset under the action of the elastic member 150 to form a movable abutment portion 160, and then the first driver 400 retracts the first pressing roller 130 and the second pressing roller 140 to the movable frame 120 to prepare for the next compaction of the corner mark.

[0051] like Figure 1As shown, the present disclosure further provides a corner labeling machine 1, comprising the corner label reinforcement device 10 described in any of the above embodiments, so that the additional corner label reinforcement device 10 can achieve more comprehensive reinforcement of the newly affixed corner label, effectively reduce the compaction blind area of the corner label, and thus improve the connection strength between the corner label and the carton.

[0052] Compared with the prior art, the present disclosure has at least the following advantages:

[0053] Since the movable frame 120 is movably and tiltedly arranged on one side of the conveying assembly 20, the first pressure roller 130 and the second pressure roller 140 arranged on the movable frame 120 can form an angle with the conveying assembly 20, ensuring that the movable abutment portion 160 formed subsequently can be set corresponding to the corner mark of the carton; when in use, the movable frame 120 and the side stop assembly 20 are connected to an external driver, and when the carton with the corner mark just affixed is transported to the preset position by the conveying assembly 20, the movable frame 120 and the side stop assembly 20 can be moved to the conveying assembly 20 under the action of the external driver. As the carton of the conveying assembly 20 approaches, the side stop assembly 200 can limit the carton on the conveying assembly 20, effectively preventing it from moving, and the movable frame 120 can approach the carton of the conveying assembly 20. Since the first pressure roller 130 and the second pressure roller 140 are respectively rotatably arranged on the movable frame 120, and the first pressure roller 130 and the second pressure roller 140 abut against each other to form a movable abutting portion 160, the gap between the first pressure roller 130 and the second pressure roller 140 is effectively reduced, and since the movable abutting portion 160 is relative to the corner mark of the carton, the movable abutting portion 160 is relatively close to the corner mark of the carton. The corresponding arrangement makes it possible for the movable abutting portion 160 to abut against the corner mark of the carton, and the first pressure roller 130 and the second pressure roller 140 to continue to be driven by the external driver, so that the movable abutting portion 160 can be elastically rotated and stretched when blocked by the carton, so that the movable abutting portion is in the process of elastic rotation and stretching, and the first pressure roller 130 and the second pressure roller 140 can respectively rotate and abut against the corner mark, that is, the first pressure roller 130 and the second pressure roller 140 can simultaneously move from the movable abutting portion 160 to both sides of the corner mark. The first pressing roller 130 and the second pressing roller 140 are rotated and abutted, so that the corner label can be pressed against the carton more comprehensively during the process of rotating and abutting, effectively reducing the compaction blind area of the corner label, thereby improving the connection strength between the corner label and the carton, that is, reinforcing the corner label, thereby reducing the probability of the corner label falling off. At the same time, with the use of the elastic member 150, when the external force disappears, such as the blocking force of the carton, the first pressing roller 130 and the second pressing roller 140 will be reset under the action of the elastic member 150, so as to prepare for the next compaction of the corner label.

[0054] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
