Description

Technical Field

[0001] This application relates to the field of cigarette production equipment technology, and in particular to a stop mechanism and a blank feeding device. Background Technology

[0002] The box blank feeding device for the box packing machine is a temporary storage and supply device for the box blanks to be formed. Its function is to store the box blank stacks and take out individual box blanks from the stacks to transport them to the next stage.

[0003] The pushing component of the blank feeding device is used to push the blank from the storage station to the gripping station. At the gripping station, the blank is positioned by the baffle, the stop and the pushing component of the pushing component, so that the robot can grip the blank.

[0004] In related technologies, the stop component includes brush bristles. Utilizing the softness of the brush bristles, they provide deceleration and positioning for the blank, effectively preventing damage to the blank while stopping it. However, brush bristles are consumable parts, easily becoming damaged after a certain period of use. This significantly reduces their deceleration effect, leads to inaccurate blank positioning, and causes the blank to collide with the damaged bristles, resulting in unstable blank picking by the robotic arm, easy blank falling, and other abnormalities, affecting the operating efficiency of the blank feeding device. Utility Model Content

[0005] Therefore, it is necessary to provide a stop mechanism and a blank feeding device to address the issues of easily damaged brush bristles and various abnormalities that occur after brush bristle damage.

[0012] In one embodiment, the bracket is provided with a first through hole; the first guide is inserted through the first through hole; and a first thread structure is provided on the outer wall of the end of the first guide away from the stop member.

[0013] The first fastener passes through the end of the first guide member away from the stop member and is threadedly engaged with the first threaded structure. The first fastener abuts against the side of the bracket away from the stop member.

[0014] In one embodiment, the connection assembly includes a second guide and a third fastener;

[0015] The second guide member passes through the first through hole; the second guide member has a guide channel inside; the first guide member passes through the guide channel; the second guide member has a first limiting block at one end near the stop member, and the first limiting block abuts against the side of the bracket near the stop member; the second guide member has a second threaded structure at the other end away from the stop member.

[0016] The third fastener is threadedly engaged with the second threaded structure; the third fastener abuts against the side of the bracket away from the stop; the first fastener abuts against the other end of the second guide away from the stop.

[0017] In one embodiment, the stop member has a second through hole that mates with the first guide member; the side of the stop member away from the bracket has a countersunk hole that communicates with the second through hole;

[0018] The first guide member has one end near the stop member inserted into the second through hole; a third thread structure is provided on the outer wall of the first guide member near the stop member.

[0019] The second fastener is disposed in the countersunk hole and is threadedly engaged with the third threaded structure.

[0020] In one embodiment, the connecting assembly further includes a fourth fastener disposed on the side of the stop member near the bracket; the fourth fastener passes through the first guide member and is threadedly engaged with the third threaded structure; the fourth fastener abuts against the side of the stop member near the bracket; and the elastic member abuts against the fourth fastener.

[0021] In one embodiment, the fourth fastener includes a flange nut; the elastic element abuts against the flange face of the flange nut.

[0022] In one embodiment, the bracket includes a main body and a connecting part; the first guide passes through the main body and the stop, one end of the first guide is connected to the main body via the first fastener; the other end of the first guide is connected to the stop via the second fastener.

[0023] The connecting part is located on one side of the main body and is perpendicular to the main body; the connecting part is located on the same side as the stop member; and a connecting hole is provided on the connecting part.

[0024] In one embodiment, the stop member has a buffer layer on the side away from the bracket.

[0025] Secondly, embodiments of this application provide a box blank feeding device, including a feeding mechanism and a stop mechanism according to any of the above embodiments;

[0026] The feeding mechanism includes a mounting frame, a hopper, and a pushing component; the mounting frame includes a first end and a second end that are arranged opposite to each other; the hopper is located at the first end and is used to hold multiple stacked blanks; the pushing component is used to push the blanks in the hopper from the first end to the second end one by one.

[0028] The aforementioned stopping mechanism comprises a first guide member passing through the bracket and the stopping member. One end of the first guide member is connected to the bracket via a first fastener; the other end of the first guide member is connected to the stopping member via a second fastener. An elastic member passes through the first guide member and is located between the bracket and the stopping member. One end of the elastic member abuts against the stopping member, and the other end abuts against the bracket. Thus, when the stopping mechanism is applied to the blank feeding device to stop and position the blank, the stopping member abuts against the blank. Under the inertial force of the blank, the elastic member located between the bracket and the stopping member first undergoes a certain compression, thereby decelerating the blank. Then, the elastic member returns to its initial position, causing the stopping member to return to its initial position. The stopping member limits the blank, keeping its position constant and preventing damage to the blank's port from inertial forces. In other words, this application replaces the brush bristles in related technologies with elastic components. The elastic deformation and subsequent reset of the elastic components achieve deceleration and accurate positioning of the blank, overcoming the problems caused by damaged brush bristles, such as poor deceleration, inaccurate positioning, unstable robotic arm handling of the blank, and easy blank falling. This improves the operating efficiency of the blank feeding device and increases production efficiency. Furthermore, due to the elasticity of the elastic components, the stop mechanism can be used for blanks of different specifications. As long as the deformation of the elastic components is within their elastic range, there is no need to adjust the position of the stop mechanism, thus saving the time required for adjustment and improving the operating efficiency of the blank feeding device. This also shortens the time required to transport the blank to the next stage, thereby increasing production efficiency. In addition, eliminating easily damaged parts such as brush bristles extends the service life of the stop mechanism and reduces its procurement cost. Attached Figure Description

[0047] See Figure 1 , Figure 2 and Figure 9 , Figure 1 The following are schematic diagrams of the stop mechanism in some embodiments of this application; Figure 2 An exploded structural diagram of the stop mechanism in some embodiments of this application is shown; Figure 9 The diagram shows a schematic representation of the stop mechanism used in a blank feeding device in some embodiments of this application.

[0048] One embodiment of this application provides a stop mechanism 10 for a box blank feeding device 1. The stop mechanism 10 is used to stop the box blank 40, thereby achieving deceleration and positioning of the box blank 40.

[0049] The stopping mechanism 10 includes a bracket 11, a stop member 12, and a connecting assembly 13. The stop member 12 is located on one side of the bracket 11. The connecting assembly 13 includes a first guide member 131, an elastic member 132, a first fastener 133, and a second fastener 134. The first guide member 131 passes through the bracket 11 and the stop member 12. One end of the first guide member 131 is connected to the bracket 11 via the first fastener 133. The other end of the first guide member 131 is connected to the stop member 12 via the second fastener 134. The elastic member 132 passes through the first guide member 131. The elastic member 132 is located between the bracket 11 and the stop member 12. One end of the elastic member 132 abuts against the stop member 12, and the other end of the elastic member 132 abuts against the bracket 11.

[0050] The stop mechanism 10 provided in this application embodiment has a first guide member 131 passing through a bracket 11 and a stop member 12. One end of the first guide member 131 is connected to the bracket 11 through a first fastener 133; the other end of the first guide member 131 is connected to the stop member 12 through a second fastener 134; an elastic member 132 passes through the first guide member 131; the elastic member 132 is located between the bracket 11 and the stop member 12; one end of the elastic member 132 abuts against the stop member 12, and the other end of the elastic member 132 abuts against the bracket 11. Thus, when the stop mechanism 10 is applied to the blank feeding device 1 to stop and position the blank 40, the stop member 12 abuts against the blank 40. Under the action of the inertial force of the blank 40, the elastic member 132 located between the support 11 and the stop member 12 is first compressed to a certain extent, thereby decelerating the blank 40. Then, the elastic member 132 returns to its initial position, driving the stop member 12 to return to its initial position. The stop member 12 limits the blank 40, keeping the position of the blank 40 constant, while avoiding damage to the port of the blank 40 by the inertial force. In other words, this application uses the elastic member 132 to replace the bristles in the related technology, and uses the elastic deformation of the elastic member 132 and the reset after elastic deformation to achieve deceleration and accurate positioning of the blank 40. This overcomes the abnormalities caused by damaged bristles, such as poor deceleration effect, inaccurate positioning, unstable picking up of the blank 40 by the robot arm, and easy falling of the blank 40, thereby improving the operating efficiency of the blank feeding device 1 and increasing production efficiency. Furthermore, due to the elasticity of the elastic element 132, the stop mechanism 10 can be used to stop blanks of different specifications. As long as the deformation of the elastic element 132 is within its elastic range, there is no need to adjust the position of the stop mechanism 10, thereby saving the time required for adjusting the position of the stop mechanism 10. This improves the operating efficiency of the blank feeding device 1 and shortens the time required to transport the blank 40 to the next stage, thus improving production efficiency. In addition, eliminating easily worn parts such as brushes can extend the service life of the stop mechanism 10 and reduce its procurement cost.

[0051] In one embodiment, see [reference] Figure 1 and Figure 2 As shown, the connecting component 13 includes a plurality of first guide members 131 and a plurality of elastic members 132. The plurality of first guide members 131 are arranged in parallel at intervals and all pass through the bracket 11 and the stop member 12. The plurality of elastic members 132 are all located between the bracket 11 and the stop member 12, and the plurality of elastic members 132 are correspondingly passed through the plurality of first guide members 131.

[0052] Specifically, see Figure 1 and Figure 2As shown, the connecting component 13 may include two first guide members 131 and two elastic members 132. The two first guide members 131 are arranged parallel to each other and pass through the bracket 11 and the stop member 12. The two elastic members 132 are arranged between the bracket 11 and the stop member 12 and pass through the two first guide members 131 in a one-to-one correspondence.

[0053] Therefore, when the blank 40 abuts against the stop 12, under the inertia of the blank 40, the stop 12 presses against multiple elastic elements 132. While being pressed, the multiple elastic elements 132 provide a reaction force to the stop 12, so that the force on the stop 12 is balanced, preventing the stop 12 from tilting, thereby preventing the blank 40 from shifting position and improving the positioning accuracy of the blank 40.

[0054] In one embodiment, see [reference] Figure 1 , Figure 3 and Figure 4 As shown, the bracket 11 is provided with a first through hole 11a; a first guide member 131 passes through the first through hole 11a; a first threaded structure 1311 is provided on the outer wall of the end of the first guide member 131 away from the stop member 12; a first fastener 133 passes through the end of the first guide member 131 away from the stop member 12 and is threadedly engaged with the first threaded structure 1311; the first fastener 133 abuts against the side of the bracket 11 away from the stop member 12.

[0055] Therefore, when the blank 40 abuts against the stop 12, under the inertia of the blank 40, the stop 12 presses against the elastic member 132, the first guide member 131 slides along the first through hole 11a, the first fastener 133 moves away from the bracket 11, and the elastic member 132 is compressed to a certain extent, thereby decelerating the blank 40; then the elastic member 132 recovers its elasticity, driving the stop 12 and the first guide member 131 to move, the first fastener 133 on the first guide member 131 abuts against the bracket 11 again, the stop 12 returns to its initial position, and the stop 12 positions the blank 40 so that the position of the blank 40 remains constant. By rotating the first fastener 133 around the first threaded structure 1311, the axial position of the first fastener 133 on the first guide 131 can be adjusted, thereby adjusting the preload and stroke of the elastic element 132. This allows the stop mechanism 10 to be used for stops of different specifications of blanks 40 without adjusting the position of the stop mechanism 10, thus saving the time required for adjusting the position of the stop mechanism 10. This improves the operating efficiency of the blank feeding device 1 and shortens the time required to transport the blanks 40 to the next stage, thereby improving production efficiency.

[0056] Further, see Figure 2As shown, the first fastener 133 includes a counter nut, which includes a fastening nut 1331 and a locking nut 1332. The first thread structure 1311 includes a fastening thread section (not shown) and a locking thread section (not shown). The fastening thread section is located on the side of the locking thread section near the bracket 11. The thread direction of the fastening thread section is opposite to that of the locking thread section. The fastening nut 1331 is threadedly engaged with the fastening thread section, and the locking nut 1332 is threadedly engaged with the locking thread section. The locking nut 1332 abuts against the fastening nut 1331.

[0057] Therefore, by including a counter nut in the first fastener 133, the connection reliability between the first fastener 133 and the first guide 131 can be reduced, thereby reducing the risk of the first fastener 133 becoming loose.

[0058] Furthermore, the first guide member 131 and the first through hole 11a are in clearance fit, which allows the first guide member 131 to slide along the first through hole 11a, reducing the friction between the first guide member 131 and the first through hole 11a, reducing the probability of damage to the first guide member 131 and the bracket 11, and extending the service life of the stop mechanism 10.

[0059] For example, see Figure 4 As shown, the first guide member 131 can be a rod-shaped structure, specifically, the first guide member 131 can be a guide rod.

[0060] In one embodiment, see [reference] Figure 2 , Figure 7 and Figure 8 As shown, the connecting assembly 13 includes a second guide 135 and a third fastener 136; the second guide 135 passes through the first through hole 11a; the second guide 135 has a guide channel 1351 inside; the first guide 131 passes through the guide channel 1351; the second guide 135 has a first limiting block 1352 at one end near the stop 12, and the first limiting block 1352 abuts against the side of the bracket 11 near the stop 12; the other end of the second guide 135 away from the stop 12 has a second threaded structure 1353; the third fastener 136 is threadedly engaged with the second threaded structure 1353; the third fastener 136 abuts against the side of the bracket 11 away from the stop 12; the first fastener 133 abuts against the other end of the second guide 135 away from the stop 12.

[0061] Therefore, by setting a second guide member 135, which has a guide channel 1351 inside, and the first guide member 131 passing through the guide channel 1351, the second guide member 135 can provide support and guidance for the first guide member 131, improving the smoothness of the first guide member 131's movement along the first through hole 11a, so that the stop mechanism 10 can better stop the blank 40 and improve the positioning accuracy of the blank 40. In addition, the second guide member 135 can separate the first guide member 131 from the first through hole 11a of the bracket 11, which can reduce the friction between the first guide member 131 and the first through hole 11a, reduce the probability of damage to the first guide member 131 and the bracket 11, and extend the service life of the stop mechanism 10.

[0062] Further, see Figure 7 and Figure 8 As shown, the second guide member 135 can be a guide sleeve; the guide sleeve is constructed with a guide channel 1351 through which the first guide member 131 passes; a first limiting block 1352 is provided on the side of the guide sleeve near the stop member 12; a second threaded structure 1353 is provided on the outer wall of the other end of the guide sleeve away from the stop member 12; the guide sleeve passes through the first through hole 11a; the first limiting block 1352 abuts against the side of the bracket 11 near the stop member 12; the third fastener 136 is threadedly engaged with the second threaded structure 1353, thereby fixing the second guide member 135 on the bracket 11.

[0063] Furthermore, the second guide member 135 can be made of a highly wear-resistant material such as an alloy material; in this way, the service life of the second guide member 135 can be extended, thereby extending the service life of the stop mechanism 10.

[0064] Furthermore, the first guide member 131 can be fitted with the guide channel 1351 with a clearance, so that the first guide member 131 has a rotational degree of freedom and the stop member 12 has a rotational degree of freedom. When the robot arm grabs the blank 40, the stop member 12 can rotate a certain angle away from the blank 40 so that the blank 40 is separated from the stop member 12, thus preventing the blank 40 from falling off the robot arm due to the obstruction of the stop member 12.

[0065] In one embodiment, see [reference] Figure 1 , Figures 4 to 6 As shown, the stop member 12 has a second through hole 121 that mates with the first guide member 131; the stop member 12 has a countersunk hole 122 that communicates with the second through hole 121 on the side away from the bracket 11; the end of the first guide member 131 near the stop member 12 passes through the second through hole 121; a third threaded structure 1312 is provided on the outer wall of the end of the first guide member 131 near the stop member 12; the second fastener 134 is provided in the countersunk hole 122 and is threadedly engaged with the third threaded structure 1312.

[0066] Therefore, by threading the second fastener 134 with the third threaded structure 1312, the connection between the first guide member 131 and the stop member 12 can be facilitated. By providing a countersunk hole 122 communicating with the second through hole 121 on the side of the stop member 12 away from the bracket 11, the second fastener 134 is placed in the countersunk hole 122 and threaded with the third threaded structure 1312. In this way, the second fastener 134 can be prevented from protruding from the side of the stop member 12 away from the bracket 11, thereby avoiding unnecessary damage to the blank 40 caused by the second fastener 134 and the first guide member 131.

[0067] In one embodiment, see [reference] Figure 1 , Figure 2 and Figure 4 As shown, the connecting assembly 13 also includes a fourth fastener 137, which is located on the side of the stop 12 near the bracket 11; the fourth fastener 137 passes through the first guide 131 and is threadedly engaged with the third threaded structure 1312; the fourth fastener 137 abuts against the side of the stop 12 near the bracket 11; the elastic member 132 abuts against the fourth fastener 137.

[0068] Therefore, by cooperating with the fourth fastener 137 and the second fastener 134, the first guide 131 and the stop 12 can be reliably connected, reducing the probability of the stop 12 falling off.

[0069] In one embodiment, see [reference] Figure 2 As shown, the fourth fastener 137 includes a flange nut 137a; the elastic element 132 abuts against the flange face of the flange nut 137a.

[0070] This increases the contact area between the elastic element 132 and the fourth fastener 137, improves the stability of the elastic element 132's extension and retraction, and ensures that the stop mechanism 10 can better stop the blank 40, thereby achieving deceleration and accurate positioning of the blank 40.

[0071] Further, see Figure 2 As shown, the stop mechanism 10 also includes a washer 14, which is sleeved on the first guide member 131. One end of the washer 14 abuts against the side of the bracket 11 near the stop member 12, and the other end of the washer 14 abuts against the elastic member 132.

[0072] This increases the contact area between the elastic element 132 and the bracket 11, improves the stability of the elastic element 132's extension and retraction, and ensures that the stop mechanism 10 can better stop the blank 40, thereby achieving deceleration and accurate positioning of the blank 40.

[0073] In one embodiment, see [reference] Figure 3As shown, the bracket 11 includes a main body 111 and a connecting part 112. A first guide member 131 passes through the main body 111 and the stop member 12. One end of the first guide member 131 is connected to the main body 111 by a first fastener 133. The other end of the first guide member 131 is connected to the stop member 12 by a second fastener 134. The connecting part 112 is located on one side of the main body 111 and is perpendicular to the main body 111. The connecting part 112 is located on the same side as the stop member 12. A connecting hole 113 is provided on the connecting part 112.

[0074] Therefore, when the stop mechanism 10 is used in the blank feeding device 1, the bracket 11 can be connected to the blank feeding device 1 via the connecting part 112, and the main body 111 of the bracket 11 can be connected to the stop member 12 via the connecting assembly 13, thereby facilitating the installation of the entire stop mechanism 10 onto the blank feeding device 1. A connecting hole 113 is provided on the connecting part 112, so that the connecting part 112 can be easily fixed to the blank feeding device 1 using fasteners, thereby facilitating the installation of the entire stop mechanism 10 onto the blank feeding device 1.

[0075] Further, see Figure 3 As shown, the bracket 11 can be L-shaped. Specifically, the connecting part 112 of the bracket 11 is connected to one end of the main body 111 and is perpendicular to the main body 111. In this way, the structural strength of the bracket 11 can be improved, the probability of the bracket 11 deforming when the stop mechanism 10 stops the blank 40 can be reduced, and the positioning accuracy of the blank 40 can be improved.

[0076] Further, see Figure 3 As shown, multiple connecting holes 113 can be provided on the connecting part 112, and the connecting holes 113 can be elongated slots. In this way, on the one hand, by providing multiple connecting holes 113 on the connecting part 112, the connecting part 112 and the blank feeding device 1 are connected at multiple points, which can improve the reliability of the connection between the connecting part 112 and the blank feeding device 1; on the other hand, by making the connecting holes 113 elongated slots, the position of the bracket 11 on the blank feeding device 1 can be easily adjusted, thereby facilitating the adjustment of the position of the entire stop mechanism 10, so that the stop member 12 of the stop mechanism 10 remains flush with the port of the blank 40 when the elastic member 132 returns to its initial position. In this way, the blank 40 can be positioned while avoiding damage to the port of the blank 40.

[0077] Furthermore, the bracket 11 can be made of stainless steel, which makes the bracket 11 have greater hardness and strength. The bracket 11 can effectively support the stop 12, so that the stop 12 can better stop the box blank 40, thereby improving the positioning accuracy of the box blank 40.

[0078] In one embodiment, the side of the stop 12 away from the bracket 11 is provided with a buffer layer (not shown).

[0079] Therefore, the buffer layer acts as a buffer when the blank 40 comes into contact with the stop 12, which can reduce the damage to the port of the stop 12 and the blank 40.

[0080] In one embodiment, the stop 12 may be a block structure, and the stop 12 may be made of nylon material.

[0081] Secondly, see Figure 9 As shown, this application provides a box blank feeding device 1, including a feeding mechanism and a stop mechanism 10 as described in any of the above embodiments; the feeding mechanism includes a mounting frame 20, a hopper (not shown), and a pushing component 30; the mounting frame 20 includes a first end 21 and a second end 22 disposed opposite to each other; the hopper is located at the first end 21 and is used to place multiple stacked box blanks 40; the pushing component 30 is used to push the box blanks 40 in the hopper one by one from the first end 21 to the second end 22; the bracket 11 of the stop mechanism 10 is connected to the second end 22 of the mounting frame 20; the stop member 12 is located on the side of the bracket 11 close to the mounting frame 20; the stop member 12 of the stop mechanism 10 is used to abut against the box blanks 40 to stop the box blanks 40 pushed by the pushing component.

[0082] Therefore, when the pushing component 30 pushes the blank 40 from the first end 21 to the second end 22, the blank 40 abuts against the stop member 12 of the stop mechanism 10. Under the action of the inertial force of the blank 40, the elastic member 132 located between the support 11 and the stop member 12 is compressed to a certain extent, thereby decelerating the blank 40. Then the elastic member 132 returns to the initial position, driving the stop member 12 to return to the initial position. The stop member 12 limits the blank 40, so that the position of the blank 40 remains constant, thereby stopping the blank 40 and avoiding damage to the port of the blank 40 by the inertial force. Furthermore, the stop mechanism 10 of this application replaces the brush bristles in related technologies with an elastic element 132. The elastic deformation and subsequent reset of the elastic element 132 achieve deceleration and accurate positioning of the blank 40, overcoming the problems caused by damaged brush bristles, such as poor deceleration, inaccurate positioning, unstable robotic arm gripping of the blank 40, and easy drop of the blank 40. This improves the operating efficiency of the blank feeding device 1 and increases production efficiency. Moreover, due to the elasticity of the elastic element 132, the stop mechanism 10 can be used to stop blanks of different specifications. As long as the deformation of the elastic element 132 is within its elastic range, there is no need to adjust the position of the stop mechanism 10, thus saving the time required for position adjustment and improving the operating efficiency of the blank feeding device 1. This also shortens the time required to transport the blank 40 to the next stage, thereby increasing production efficiency. In addition, eliminating easily damaged parts such as brush bristles extends the service life of the stop mechanism 10 and reduces its procurement cost.

[0083] It should be noted that, for reference Figure 9 As shown, the blank feeding device 1 may include multiple stop mechanisms 10, which are spaced apart at the second end of the mounting frame 20.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
