[0055] The present invention provides a material pushing device 100 .

[0056] Reference Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of a material pushing device 100 according to an embodiment of the present invention; Figure 2 This is a schematic diagram of the overall top view of the material pushing device 100 according to an embodiment of the present invention; Figure 3 This is a schematic side view of the entire structure of a material pushing device 100 according to an embodiment of the present invention; Figure 4 Schematic diagram of the exploded structure of the support assembly 50 and the pusher assembly 70 of an embodiment of the pusher device 100 of the present invention; Figure 5 For example Figure 4 A magnified schematic diagram of the Q part structure; Figure 6 Schematic diagram of the exploded structure of the driving mechanism 30 of an embodiment of the pushing device 100 of the present invention.

[0057] like Figures 1 to 3 As shown, the pushing device 100 includes a base plate 10 and a driving mechanism 30 and a pushing mechanism provided on the base plate 10. The pushing mechanism includes a support assembly 50, a pushing assembly 70, and a limiting assembly 80. The support assembly 50 is provided at the output end of the driving mechanism 30 and is slidably connected to the base plate 10; the pushing assembly 70 is provided on the side of the support assembly 50 away from the base plate 10, and the pushing assembly 70 is movably connected to the support assembly 50; one end of the limiting assembly 80 is provided on one of the support assembly 50 and the pushing assembly 70, and the other end is detachably connected to the other of the two. In the pushing state, the support assembly 50 and the pushing assembly 70 generate synchronous movement through the limiting assembly 80; in the stuck state, one of the support assembly 50 and the pushing assembly 70 is separated from the limiting assembly 80, so that the support assembly 50 and the pushing assembly 70 undergo relative movement.

[0058] The technical solution of the present invention adopts a support assembly 50 and a pusher assembly 70 that can move relative to each other, so that the two are relatively separated when the material is stuck, thereby solving the technical problem that continuing to drive the pusher assembly 70 when the material is stuck will damage the product to be pushed. The pusher device 100 includes a base plate 10 and a driving mechanism 30 provided on the base plate 10, a support assembly 50, a pusher assembly 70 provided on the side of the support assembly 50 away from the base plate 10, and a limit assembly 80; the pusher assembly 70 and the support assembly 50 are detachably connected through the limit assembly 80, and the output end of the driving mechanism 30 is directly connected to the support assembly 50, and drives the support assembly 50 to drive the pusher assembly 70 to slide along the base plate 10, so that the pusher assembly 70 pushes the material. When the material is pushed, the support assembly 50 and the pusher assembly 70 move synchronously through the limit assembly 80; when the material is stuck, when the resistance to pushing is greater than the connection force between the support assembly 50 and the pusher assembly 70 through the limit assembly 80, the limit assembly 80 separates from the other of the support assembly 50 and the pusher assembly 70, so that the support assembly 50 and the pusher assembly 70 move relative to each other. The movement of the support assembly 50 driven by the driving mechanism 30 will not drive the pusher assembly 70 to continue to push forward, thereby protecting the product to be pushed from being compressed, deformed or even damaged, reducing the scrap rate caused by material jamming, and effectively solving the technical problem that the product to be pushed will be damaged if the pusher assembly 70 continues to drive when the material is stuck.

[0059] Furthermore, the pushing device 100 includes a control component, which is connected to the driving mechanism 30 to control the operation of the driving mechanism 30.

[0060] Optionally, the limiting assembly 80 includes a mounting member 81 and a connecting member 82, the mounting member 81 is arranged on the pushing assembly 70; the connecting member 82 is detachably connected to the mounting member 81 and extends toward the supporting assembly 50, and the connecting member 82 is magnetically connected to the supporting assembly 50.

[0061] The support assembly 50 is connected to the mounting member 81 and is extended toward the support assembly 50. The support assembly 50 can be provided with a magnetic conductor, and the connecting member 82 is a magnetic block for magnetically connecting to the magnetic conductor of the support assembly 50, so that when the material is stuck, the force of the stuck material is greater than the force of the magnetic connection, thereby causing the support assembly 50 and the pushing assembly 70 to move relative to each other. During the sticking process, the pushing assembly 70 will suspend the pushing action, that is, under the drive of the driving mechanism 30, the pushing assembly 70 stops moving, and the support assembly 50 is driven by the pushing assembly 70 to move relative to the pushing assembly 70, thereby protecting the product to be pushed from being compressed, deformed or even damaged, reducing the scrap rate caused by the stuck material, and effectively solving the technical problem that the product to be pushed will be damaged if the pushing assembly 70 continues to drive when the material is stuck.

[0062] In the first installation method, the limit assembly 80 is arranged on the side of the pusher assembly 70 and the support assembly 50 facing away from the pushing direction. In the second installation method, the limit assembly 80 is arranged on the side of the pusher assembly 70 and the support assembly 50 facing the pushing direction. Different from the first installation method, the mounting member 81 is detachably connected to the support assembly 50, and the connecting member 82 is connected to the mounting member 81 and extends toward the pusher assembly 70. The pusher assembly 70 can be provided with a magnet, and the connecting member 82 is a magnetic block for magnetically connecting with the magnet of the pusher assembly 70. The clamping process is the same as the above principle and will not be repeated.

[0063] Furthermore, the mounting member 81 and the connecting member 82 can be designed as an integral structure or as a detachable connection. The connecting member 82 must be a magnetic conductive structure to facilitate magnetic connection and card protection.

[0064] Optionally, the limiting assembly 80 includes a fixed part and a movable part, the fixed part is provided at one of the supporting assembly 50 and the pushing assembly 70 ; the movable part is hinged to the fixed part and elastically abuts against the other of the supporting assembly 50 and the pushing assembly 70 .

[0065] In this embodiment, the fixed member is configured as a fixed block, and the movable member is hingedly connected to the fixed block and is provided with a torsion spring. The torsion spring supports the fixed and movable members to form an installation angle that aligns with the support assembly 50 and the pusher assembly 70. When material jamming occurs, if the resistance to pushing the material is greater than the elastic force of the torsion spring that maintains the installation angle between the fixed and movable members, the drive mechanism 30 drives the support assembly 50 and the pusher assembly 70 to move relative to each other to protect the product to be pushed.

[0066] The installation position and installation method of the movable member and the fixed block refer to the installation position and installation method of the above-mentioned mounting member 81 and connecting member 82. When the fixed block is installed on the support assembly 50, the movable member and the fixed block are arranged on the side of the pusher assembly 70 and the support assembly 50 facing away from the pushing direction; when the fixed block is installed on the pusher assembly 70, the movable member and the fixed block are arranged on the side of the pusher assembly 70 and the support assembly 50 facing the pushing direction.

[0067] During normal pushing, the movable part and the fixed block are set at a 90° angle, and the movable block has a blocking force on the movement of one of the two; when the material is stuck, the resistance to pushing is greater than the blocking force, and the driving mechanism 30 drives the support assembly 50 and the pushing assembly 70 to move relative to each other. Under the push of one of the two, the movable part and the fixed block present a connection angle of 180°, so that the two can move relative to each other smoothly.

[0068] Optionally, the pushing device 100 further includes a material jam detection assembly, which includes a sensing member 61 and a detection member 62. The sensing member 61 is provided in one of the pushing assembly 70 and the support assembly 50, and has a sensing slot 61A. The detection member 62 is provided in the other of the two and is used to cooperate with the sensing member 61 to detect material jams. When the detection member 62 remains inserted into the sensing slot 61A, it is determined to be in the pushing state; when the detection member 62 is separated from the sensing slot 61A, it is determined to be in the material jam state.

[0069] In this embodiment, the jam detection assembly is electrically connected to the control assembly, which is used to receive signals from the sensing element 61 and the detection element 62. The sensing element 61 of the jam detection assembly can be mounted on either the support assembly 50 or the pusher assembly 70, while the detection element 62 is mounted on either one. The connection between the two can be flexibly arranged by combining the layout settings, and the coordination between the two is used to detect the jam condition.

[0070] When pushing materials normally, the detection member 62 is arranged in the sensing slot 61A, and the driving mechanism 30 drives the support assembly 50 to move. Under the setting of the limit assembly 80, the support assembly 50 drives the pushing assembly 70 to move toward the direction of the product to be pushed to push the material. At this time, the detection member 62 is continuously arranged in the sensing slot 61A to determine that the current state is a normal pushing state.

[0071] When material jam occurs, the driving mechanism 30 will drive the supporting mechanism to move in the pushing direction. At this time, the detection part 62 will separate from the sensing slot 61A as the two move relative to each other. The control component receives the signal that the detection part 62 has separated from the sensing slot 61A, and determines that the current state is a material jam state. It then controls the driving mechanism 30 to stop driving, thereby improving the effectiveness of material jam detection and the reliability of material jam protection.

[0072] Combined with reference Figure 4 and Figure 5 As shown, optionally, the pushing device 100 also includes at least one sliding assembly 20, and the at least one sliding assembly 20 includes a first guide rail 21, a second guide rail 22 and a roller track 23, the first guide rail 21 is connected to the support assembly 50; the second guide rail 22 is connected to the pushing assembly 70; the roller track 23 is arranged between the first guide rail 21 and the second guide rail 22, and the first guide rail 21 and the second guide rail 22 are respectively slidably connected to the roller track 23.

[0073] In this embodiment, the sliding assembly 20 is configured as a cross roller guide rail, which is used to reduce the friction between the smaller pushing assembly 70 and the support assembly 50 when the two move relative to each other, so as to avoid the pushing assembly 70 moving synchronously with the support assembly 50 in the pushing direction due to the large friction, thereby avoiding reducing the protection effect and preventing the product to be pushed from being deformed or damaged by the pushing.

[0074] Furthermore, a groove 51A is provided on the side of the support seat 51 facing the push seat 71. The first guide rail 21, the second guide rail 22, and the roller track 23 are respectively disposed within the groove 51A. The first guide rail 21 and the second guide rail 22 are respectively slidably connected to the roller track 23, and the first guide rail 21 and the second guide rail 22 can be restrained by the roller track 23 so as not to disengage. The first guide rail 21 and the second guide rail 22 are respectively provided with a plurality of mounting holes 20A. The mounting holes 20A have a large diameter section 201A and a small diameter section 202A. An external fastener extends through the large diameter section 201A into the small diameter section 202A, and then passes through one end of the small diameter section 202A and is threadedly connected to the first guide rail 21 or the second guide rail 22. This improves the sliding smoothness when the push seat 72 separates from the support seat 51 during material jamming, reduces the sliding friction between the two, and facilitates material jam protection during material jamming.

[0075] The large diameter section 201A of the first guide rail 21 faces the pushing seat 71, and the small diameter section 202A of the first guide rail 21 faces the bottom wall of the groove 51A. A first threaded portion is provided on the support seat 51 corresponding to the first guide rail 21, which is used to detachably connect the support seat 51 to the first guide rail 21 through external fasteners.

[0076] The large diameter section 201A of the second guide rail 22 faces the bottom wall of the groove 51A of the support seat 51, and the small diameter section 202A of the second guide rail 22 faces the pushing seat 71. A second threaded portion is provided on the pushing seat 71 corresponding to the second guide rail 22, and the second threaded portion is used to detachably connect the pushing seat 71 and the second guide rail 22 through an external fastener.

[0077] Furthermore, the pushing device 100 also includes two sliding components 20, which are respectively arranged in the groove 51A at intervals, and the two side surfaces of each first guide rail 21 respectively abut the bottom wall and side wall of the groove 51A, thereby improving the stability of the sliding component 20 in the groove 51A.

[0078] Optionally, the base plate 10 is provided with a slide rail 40 , and the extension direction of the slide rail 40 is parallel to the pushing direction of the pushing assembly 70 ; the support assembly 50 is provided with a slide seat 52 on the side facing away from the pushing assembly 70 , and the slide seat 52 is slidably connected to the slide rail 40 .

[0079] In this embodiment, the support assembly 50 is provided with a support seat 51 and a slide seat 52. The support seat 51 is connected to the driving mechanism 30. The slide seat 52 is provided on the side of the support seat 51 away from the pushing assembly 70. A slide groove 52A is provided on the slide seat 52. The slide rail 40 slides with the slide groove 52A to support the support assembly 50 and guide the sliding direction of the support assembly 50 to improve the sliding stability.

[0080] Furthermore, the pushing assembly 70 includes a pushing seat 71, a pushing rod 72 and a guide wheel group 73. A support plate is provided on one side of the bottom plate 10 in the pushing direction, and the guide wheel group 73 is provided on the support plate. The pushing seat 71 and the support seat 51 are connected through a limit assembly 80, and are slidably matched through a cross roller guide rail. One end of the pushing rod 72 is connected to the pushing seat 71, and the other end is extended toward the product to be pushed. The guide wheel group 73 is provided on the upper and lower sides or left and right sides of the pushing rod 72 to support and guide the end of the pushing rod 72 away from the pushing seat 71, thereby improving the accuracy of the pushing direction and improving the pushing efficiency.

[0081] Combined with reference Figure 6 As shown, optionally, the driving mechanism 30 includes a driving member 31, a crank 32 and a conversion member 33, and the driving member 31 is arranged on the base plate 10; the crank 32 is rotatably arranged on the base plate 10 and connected to the output shaft of the driving member 31, and the crank 32 is provided with a follower 322; one end of the conversion member 33 is connected to the support assembly 50, and the other end extends toward one end of the support assembly 50 facing the driving member 31, and the follower 322 is slidably connected to the conversion member 33.

[0082] The conventional pusher device 100 is driven by a pneumatic cylinder, which is relatively low in cost and simple in structure. In this embodiment, the driving member 31 is configured as a motor, which is connected to and driven by a control assembly. A motor connection block 311 is provided on the base plate 10, which is connected to the output shaft of the motor. The crank 32 is a ring wheel 321 and is connected to the motor connection block 311. The crank 32 is detachably connected to the motor via the motor connection block 311, and the motor drives the crank 32 to rotate via the motor connection block 311. The motor drives the crank 32 to reciprocate within a certain angle range. The conversion member 33 is detachably connected to the support seat 51 of the support assembly 50. The follower 322 is provided on the outer wall of the ring wheel 321. The ring wheel 321 is slidably connected to the conversion member 33 via the follower 322. The conversion member 33 cooperates with the crank 32 to convert the motor's rotational momentum into reciprocating linear motion through cooperation with the linear guide, thereby indirectly driving the push rod 72 to reciprocate linearly, changing the driving method and improving driving convenience.

[0083] Furthermore, the motor is configured as a stepper motor or a servo motor, and its rotation speed is adjustable. Compared with the traditional cylinder drive, the pushing speed can be adjusted and can be stopped at any time, thereby improving the reliability of the material jam protection.

[0084] It is understandable that the rotation angle of the motor-driven crank 32 is preferably a reciprocating rotation between 0° and 180°, and the 0° to 180° swing of the motor is the key to controlling the telescopic limit position of the push rod 72.

[0085] It is understandable that the present invention may also not set up a separate control component, but connect the sensing element 61 and the control board of the motor, directly receive the feedback signal through the control board of the motor and judge the jamming condition, thereby controlling the driving state and driving parameters of the motor through the control board of the motor.

[0086] Optionally, a conversion groove 33A is opened in the middle of the conversion member 33, and the follower part 322 slides through the conversion groove 33A. The sliding direction of the follower part 322 in the conversion groove 33A is set at an angle to the pushing direction of the pushing assembly 70.

[0087] In this embodiment, the driving mode is changed to motor drive, and the motor drives the crank 32 to rotate. The follower 322 of the crank 32 is connected to a sliding column 324. The sliding column 324 is arranged in the conversion groove 33A, and during the rotation of the crank 32, it rotates relative to the groove wall of the conversion groove 33A and slides along the length extension direction of the conversion groove 33A. The length extension direction of the conversion groove 33A is perpendicular to the pushing direction, so that the overall driving space and pushing space of the pushing device 100 are flexibly arranged, which improves the space utilization and flexibility of the space layout compared to the cylinder drive. The motor drive has higher stability and higher flexibility in controlling the pushing process.

[0088] Furthermore, the driving mechanism 30 also includes two buffers, which are stops 36. The two stops 36 are respectively arranged on both sides of the base plate and on both sides of the crank 32. The stops 36 are used to buffer the rotational inertia of the crank 32. During rotation, the rotation of the crank 32 drives the follower 322 to rotate synchronously. The follower 322 approaches or comes close to the stopper 36, and the crank 32 stops rotating in this direction and reverses rotation.

[0089] Optionally, the follower 322 is provided with a baffle 323, and the driving mechanism 30 further includes an initial sensor 34 and an in-position sensor 35. The initial sensor 34 is provided on the base plate 10 and is located on one side of the crank 32; the in-position sensor 35 is provided on the base plate 10 and is located on the other side of the crank 32 different from the initial sensor 34. The baffle 323 is used to block the initial sensor 34 or the in-position sensor 35; wherein, when the baffle 323 blocks the initial sensor 34, the driving member 31 drives the follower 322 to rotate toward the in-position sensor 35; when the baffle 323 blocks the in-position sensor 35, the driving member 31 drives the follower 322 to rotate toward the initial sensor 34.

[0090] In this embodiment, the end of the follower 322 away from the crank 32 is connected to the side of the conversion member 33 with a sliding column 324, and the side facing away from the conversion member 33 is provided with a baffle 323. The initial sensor and the in-position sensor 35 are respectively connected to the control component, or respectively connected to the control board of the motor to feedback the rotation state of the motor. The baffle 323 reciprocates between the initial sensor 34 and the in-position sensor 35 as the follower 322 is driven by the motor and slides in the conversion slot 33A. The initial sensor and the in-position sensor 35 are installed on the base plate 10. When the two are at the 0° and 180° positions of the motor, the line connecting the two is the pushing direction. The initial sensor 34 and the in-position sensor 35 are used to control the swing angle of the servo motor (280). The initial sensor 34 and the in-position sensor 35 are respectively detachably connected to the base plate 10, and the installation position can be adaptively adjusted according to the pushing distance.

[0091] Furthermore, the driving mechanism 30 also includes two sheet metal parts 37 for installing the initial sensor 34 and the in-position sensor 35. The two sheet metal parts 37 are respectively protruded from the two side edges of the base plate 10. The two sheet metal parts 37 are adapted to the length of the follower part 322 so that the baffle 323 can smoothly sense the initial sensor 34 or the in-position sensor 35, thereby improving the sensing coordination efficiency.

[0092] It is understandable that the two buffer members 36 can cooperate with the initial sensor 34 and the in-position sensor 35 to limit the rotation of the crank 32 to avoid excessive rotation.

[0093] The present invention further provides a packaging device (not shown) comprising a frame and a pusher device 100 as described above. The specific structure of the pusher device 100 is similar to that of the aforementioned embodiments. Since the present packaging device utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects provided by the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here. A transfer track is provided on the frame, and the pusher device 100 is disposed on the frame to push materials onto the transfer track.

[0094] In this embodiment, the pushing device 100 is driven by a motor, and the crank 32 and the conversion part 33 cooperate with the linear guide to convert the rotational momentum of the motor into reciprocating linear motion, thereby indirectly driving the push rod 72 to reciprocate linearly, changing the driving mode, improving the driving convenience, and improving the spatial layout flexibility of the packaging equipment.
