Description

Technical Field

[0001] The invention relates to the technical field of palletizing, and in particular to a sheet piece guiding device and a sheet piece palletizing device. Background Art

[0002] After the aluminum sheets are produced and formed, they need to be stacked for easy storage and transportation. In order to improve the stacking neatness of the aluminum sheets and reduce the possibility of elliptical sheets getting stuck at the blanking port, the applicant has improved the existing stacking device, and the improved solution is presented in the patent application with publication number CN119059183A, namely, a material receiving structure, a stacking device and a stacking line.

[0003] In this improved scheme, the material receiving structure includes a base body, at least two rear limit rods and at least two second limit rods. The base body is provided with a drop opening for the stacking sheets to pass downward. At least two of the rear limit rods are respectively vertically arranged at the left rear and right rear parts of the drop opening. At least two of the second limit rods are respectively vertically arranged at the left front and right front parts of the drop opening. The upper sections of at least two of the second limit rods are active rotating sections that actively rotate during the material receiving process of the material receiving structure.

[0004] The improved scheme is to set the upper section of the rear limit rod to a structure that is inclined from bottom to top and outward. On the one hand, the upper section of the rear limit rod can guide the sheet to be stacked to slide down, especially when the sheet to be stacked is inclined, the edge of the higher side of the sheet to be stacked is supported on the upper section of the rear limit rod. Since the upper section of the rear limit rod is an inclined structure, the sheet to be stacked can slide smoothly along the upper section of the rear limit rod to the sheet connection position; on the other hand, since the upper section of the rear limit rod is inclined from bottom to top and outward, respectively, the upper end of the rear limit rod is closer to the outside, which can reduce or even avoid the sheet to be stacked output from the conveying component from contacting the upper end of the rear limit rod during the falling process, thereby reducing or even avoiding the possibility of the sheet to be stacked being scratched by the upper end of the rear limit rod, and can reduce or even avoid the situation where the sheet to be stacked contacts the upper end of the rear limit rod during the falling process and causes the sheet to be stacked to be stuck.

[0005] However, in actual use, it was found that the improved solution had the following technical problems: During the stacking process of aluminum sheets, the front part of the aluminum sheet leaves the conveyor belt first, causing the aluminum sheet to tilt downward from back to front during the falling process. It is easy for the front edge of the aluminum sheet to be supported on the receiving tray or the aluminum sheet on the receiving tray and the rear part of the aluminum sheet to be supported on the upper section of the rear limit rod. Some aluminum sheets can slide off the upper section of the rear limit rod, while some aluminum sheets will be obliquely supported between the upper section of the rear limit rod and the receiving tray (or the aluminum sheet on the receiving tray), which will have an adverse effect on the stacking operation.

[0006] Especially for the longitudinally stacked elliptical aluminum sheets and longitudinally stacked waist-shaped aluminum sheets, their long axes are arranged in the front-to-back direction, and the process of sliding off the conveyor belt is longer. When sliding, the downward tilt from the back to the front is greater, and it is easier to be diagonally supported between the upper section of the rear limit rod and the receiving tray (or the aluminum sheets on the receiving tray). In fact, the above-mentioned improvement scheme is prone to the problem of the elliptical aluminum sheets and waist-shaped aluminum sheets being diagonally supported between the upper section of the rear limit rod and the receiving tray (or the aluminum sheets on the receiving tray) when performing longitudinal stacking of the elliptical aluminum sheets and waist-shaped aluminum sheets. In fact, the stacking devices in the prior art are basically unable to achieve longitudinal stacking of the elliptical aluminum sheets and waist-shaped aluminum sheets. Summary of the invention

DETAILED DESCRIPTION

[0021] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0022] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0023] like Figures 1 to 3The sheet-like member guiding device shown in the figure is suitable for use in a stacking device for stacking sheet-like members. The sheet-like member guiding device comprises a base body 1, at least two front limit rods and at least two rear limit rods 2. A feeding port 101 is provided on the base body 1. The at least two front limit rods are respectively vertically arranged at the left front part and the right front part of the feeding port 101. The at least two rear limit rods 2 are respectively vertically arranged at the left rear part and the right rear part of the feeding port 101. The lower sections 20 of the at least two rear limit rods 2 are 1 is vertical, the upper sections 202 of at least two rear limiting rods 2 are respectively inclined outward from bottom to top, the at least two front limiting rods and the at least two rear limiting rods 2 constitute a guiding structure for guiding the sheet-like member, and at least one of the at least two rear limiting rods 2 is correspondingly provided with an actuating device 5, which is used to move the sheet-like member obliquely supported on the upper section 202 of the rear limiting rod 2 corresponding thereto forward and downward, so as to adjust the sheet-like member from an inclined state to a horizontal state.

[0024] By adopting the above technical scheme, by setting the upper section 202 of the rear limit rod 2 to be inclined from bottom to top toward the outside, on the one hand, the upper section 202 of the rear limit rod 2 can play a role in guiding the sheet member to slide down, especially when the sheet member is inclined, the rear part of the sheet member is supported on the upper section 202 of the rear limit rod 2, and since the upper section 202 of the rear limit rod 2 is an inclined structure, the sheet member can slide down smoothly onto the receiving tray 17 along the upper section 202 of the rear limit rod 2; on the other hand, since the upper section 202 of the rear limit rod 2 is inclined from bottom to top toward the outside, the upper end of the rear limit rod 2 is closer to the outside, which can reduce or even avoid the sheet member output on the conveyor belt from contacting with the upper end of the rear limit rod 2 during the falling process, thereby reducing or even avoiding the possibility of the sheet member being scratched by the upper end of the rear limit rod 2, and can reduce or even avoid the situation where the sheet member is stuck due to contact with the upper end of the rear limit rod 2 during the falling process.

[0025] Furthermore, by providing an actuator 5, the actuator 5 is used to drive the sheet members obliquely supported on the upper section 202 of the rear limit rod 2 to move forward and downward, so as to adjust the sheet members from an inclined state to a horizontal state. This can further reduce the possibility of the sheet members getting stuck on the upper section 202 of the rear limit rod 2 due to the oblique support, thereby helping to ensure smooth stacking of the sheet members.

[0026] In particular, when the receiving tray 17 of the stacking device receives materials between the limiting rods of the guiding structure, after the sheet falls from the conveyor belt and tilts, the front edge of the sheet may be supported on the receiving tray 17 or the sheet on the receiving tray 17, and the rear of the sheet is supported on the upper section 202 of the rear limiting rod 2. At this time, the sheet is tilted and stuck at the guiding structure, making it difficult to smoothly perform the stacking work. By setting up the actuator 5, the sheet that is tilted and stuck at the guiding structure can be driven to adjust from the tilted state to the horizontal state, release the stuck state, and ensure that the stacking work can be smoothly performed.

[0027] In the above technical solution, the lower sections 201 of at least two rear limiting rods 2 are vertical. The vertical lower sections 201 of the rear limiting rods 2 can ensure the limiting of the sheet members and the neatness of the stacking of the sheet members.

[0028] As a preferred example, the rear limiting rod 2 is a bare rod consisting of an upper section 202 and a lower section 201 , and the upper section 202 of the rear limiting rod 2 is a bent rod section that bends and extends outward from bottom to top.

[0029] In some embodiments, Figures 1 to 5 As shown, the actuating device 5 includes a driving pulley 505, a trajectory limiting structure, a driving motor 504 and an actuating belt 508. The actuating belt 508 is sleeved on the driving pulley 505 and the trajectory limiting structure. The driving motor 504 drives the driving pulley 505 to rotate to drive the actuating belt 508 to move. The trajectory limiting structure limits the belt segment 509 on the actuating belt 508 that cooperates with the trajectory limiting structure to have a motion trajectory that is inclined from top to bottom and inward. The belt segment 509 on the actuating belt 508 that cooperates with the trajectory limiting structure is located at the front side of the trajectory limiting structure. The belt segment 509 on the actuating belt 508 that cooperates with the trajectory limiting structure is arranged in parallel with the upper segment 202 of the rear limiting rod 2 corresponding to the actuating device 5. The belt segment 509 on the actuating belt 508 that cooperates with the trajectory limiting structure is suitable for contacting with a sheet member obliquely supported on the upper segment 202 of the rear limiting rod 2 corresponding to the actuating device 5 to drive the sheet member to move forward and downward.

[0030] During actual use, the driving motor 504 drives the active pulley 505 to rotate, and the belt segment 509 that cooperates with the trajectory limiting structure contacts the sheet member that is obliquely supported on the upper segment 202 of the rear limit rod 2. The belt segment 509 that cooperates with the trajectory limiting structure drives the sheet member to move forward and downward through friction, so that the sheet member can fall smoothly.

[0031] In some embodiments, the track limiting structure includes a driven pulley 506 , and the movement track of the belt segment 509 is limited by using the driven pulley 506 , which is easy to implement.

[0032] In some embodiments, the trajectory limiting structure includes a plurality of driven pulleys 506 arranged in sequence along an inclined line extending obliquely outward from bottom to top. The plurality of driven pulleys 506 are used to limit the motion trajectory of the belt segment 509, so that the motion trajectory of the belt segment 509 is more consistent with the inclined or curved path of the corresponding upper segment 202 of the rear limiting rod 2.

[0033] In some embodiments, the actuating device 5 further includes one or more tensioning wheels 507 acting on the actuating belt 508 . The provision of the tensioning wheels 507 can ensure the tension of the actuating belt 508 .

[0034] As a preferred example, the cross section of the actuating belt 508 is circular.

[0035] In specific implementation, Figure 4 and Figure 5 As shown, the actuator 5 also includes a first mounting seat fixedly mounted on the seat body 1 by bolts, and the driving motor 504, the driven pulley 506 and the tensioning wheel 507 can all be mounted on the first mounting seat. As a specific example, the first mounting seat includes a base 501, a mounting portion 502 vertically arranged at the front end of the base 501, and a sliding bracket 503 slidably connected to the base 501, the driving motor 504 is mounted on the sliding bracket 503, the driving pulley 505 is mounted on the output shaft of the driving motor 504, and the driven pulley 506 is mounted on the mounting portion 502, and the sliding bracket 503 and the base 501 can be locked and unlocked by a bolt locking structure.

[0036] In a specific implementation, the rear limiting rod 2 can be mounted on the seat body 1 through the second mounting seat 6 , the second mounting seat 6 is fixedly mounted on the seat body 1 by bolts, and the lower end of the rear limiting rod 2 is fixedly mounted on the second mounting seat 6 .

[0037] In some embodiments, the actuator 5 includes an actuator wheel arranged beside the upper section 202 of the rear limit rod 2 corresponding thereto and a first electric drive mechanism for driving the actuator wheel to rotate, and the outer peripheral surface of the actuator wheel is suitable for contacting with the sheet member obliquely supported on the upper section 202 of the rear limit rod 2 corresponding to the actuator 5, so as to drive the sheet member to move forward and downward. The first electric drive mechanism can directly adopt the first motor, install the actuator wheel on the output end of the first motor, and directly drive the actuator wheel to rotate by the first motor, and the first motor can be directly or indirectly installed on the seat body 1 through a bracket. With the above technical solution, the actuator wheel is driven to rotate by the first motor, and the outer peripheral surface of the actuator wheel contacts with the sheet member obliquely supported on the upper section 202 of the rear limit rod 2, and the outer peripheral surface of the actuator wheel drives the sheet member to move forward and downward by friction, so that the sheet member can fall smoothly.

[0038] In some embodiments, in order to make the actuating wheel and the upper section 202 of the limiting rod more compatible, the upper sections 202 of at least two rear limiting rods 2 are bent and extended outward from bottom to top, the central axis of the actuating wheel is arranged horizontally, the front upper section 202 of the outer circumference of the actuating wheel is bent inward from top to bottom, and the front upper section 202 of the outer circumference of the actuating wheel and the upper section 202 of the rear limiting rod 2 corresponding to the actuating device 5 are arranged side by side. In specific implementation, the upper sections 202 of at least two rear limiting rods 2 can be arranged in an arc shape, and the radius of the arc line is consistent with the radius of the actuating wheel.

[0039] In some embodiments, Figures 1 to 3 As shown, four rear limit rods 2 are arranged at the rear of the material passing port 101, and the four rear limit rods 2 are arranged in sequence from left to right, and the positions of the two rear limit rods 2 located on the left and right sides of the four rear limit rods 2 are more forward than the positions of the two rear limit rods 2 located in the middle of the four rear limit rods 2, and the two rear limit rods 2 located on the left and right sides of the four rear limit rods 2 are respectively provided with actuating devices 5. By adopting the above technical solution, the sheet member guiding device is suitable for stacking elliptical sheets with long axes arranged in the left and right directions and waist-shaped sheets with long axes arranged in the left and right directions.

[0040] In some embodiments, Fig. 9 As shown, four rear limit rods 2 are arranged at the rear of the material passing port 101, and the four rear limit rods 2 are arranged in sequence from left to right, and the positions of the two rear limit rods 2 located on the left and right sides of the four rear limit rods 2 are more forward than the positions of the two rear limit rods 2 located in the middle of the four rear limit rods 2, and the two rear limit rods 2 located in the middle of the four rear limit rods 2 are respectively provided with an actuating device 5. By adopting the above technical solution, the sheet member guiding device is suitable for stacking elliptical sheets with long axes arranged in the front-to-back direction and waist-shaped sheets with long axes arranged in the front-to-back direction.

[0041] In some embodiments, four front limit rods are arranged at the front of the feeding port 101, and the four front limit rods include two first front limit rods 4 respectively vertically arranged at the left front and right front of the feeding port 101, and the upper sections 202 of the two first front limit rods 4 are active rotating sections that can actively rotate. In the prior art, sheet pieces are usually punched out by a punch press, such as aluminum round sheets or aluminum oval sheets. Due to the vibration of the punch press, the sheet pieces on the conveyor belt may be offset by 1-2 centimeters in the left and right directions, while the connecting piece position at the feeding port 101 is fixed, and the offset sheet pieces are easily stuck at the feeding port 101. The present application sets at least two active rotating sections, and uses the rotation of the active rotating sections to drive the sheet pieces to return to the normal position, which can prevent the sheet pieces from being stuck between the limit rods and ensure the smooth progress of the stacking work.

[0042] As a specific example, the two first front limit rods 4 each include a first core rod 401 and a sleeve 402 sleeved on the first core rod 401, and the sheet member guiding device also includes a second electric drive mechanism for driving the sleeve 402 to actively rotate. During the stacking process, the second electric drive mechanism drives the sleeve 402 to rotate, and when the edge of the sheet member contacts the outer surface of the sleeve 402, the rotation of the sleeve 402 can drive the sheet member to adjust its position to prevent the sheet member from being tilted and stuck between the limit rods. In a specific implementation, the sleeve 402 can be directly rotatably supported on the first core rod 401, or the sleeve 402 can be rotatably supported on the first core rod 401 through a bearing.

[0043] Furthermore, the sleeve 402 is mounted on the periphery of the upper section 202 of the first core rod 401, and the lower section 201 of the first core rod 401 is mounted with a plurality of first rollers 403, the outer diameters of the plurality of first rollers 403 are consistent with the outer diameter of the sleeve 402, and the plurality of first rollers 403 can all rotate relative to the first core rod 401. The first roller 403 is mounted on the lower section 201 of the first core rod 401, and generally a plurality of first rollers 403 are mounted. The first roller 403 will not actively exert force on the sheet member, and the first roller 403 helps to maintain the position of the sheet member and helps to ensure the neatness of the stacking. In a specific implementation, the first roller 403 can be implemented by a bearing mounted on the lower section 201 of the first core rod 401.

[0044] As a specific example, the second electric drive mechanism may include a second motor 10 and a transmission mechanism. The second motor 10 serves as a power source. The transmission mechanism is used to transmit the power output by the second motor 10 to the sleeve 402 to drive the sleeve 402 to rotate. The transmission mechanism may be a belt drive mechanism. The first pulley 12 of the belt drive mechanism is installed on the output shaft of the second motor 10, and the second pulley 14 of the belt drive mechanism is installed on the sleeve 402. The drive belt 13 of the belt drive mechanism is mounted on the first pulley 12 and the second pulley 14.

[0045] In some embodiments, the four front limit rods also include two second front limit rods 3, the two second front limit rods 3 are respectively vertically arranged at the left front part and the right front part of the feeding port 101, and the two second front limit rods 3 each include a second core rod and a plurality of second rollers mounted on the second core rod, and the plurality of second rollers can rotate relative to the second core rod. By adopting the above technical solution, the two second front limit rods 3 can provide a buffer for the sheet member to reduce rebound, and in the case that the incoming sheet member is offset or deflected, the passive rotation of the second roller can also be used to promote the sheet member to adjust its position, thereby promoting the sheet member to return to the correct position, and can avoid the situation where the position cannot be adjusted due to the large friction of the burrs on the edge of the sheet member when a light rod is used.

[0046] In some embodiments, the four front limit rods are arranged in sequence from left to right, the positions of the two front limit rods located on the left and right sides of the four front limit rods are further back than the positions of the two front limit rods located in the middle of the four front limit rods, and the two second front limit rods 3 are located between the two first front limit rods 4. With the above technical solution, the sheet member guiding device is suitable for stacking elliptical sheets with long axes arranged in the left and right directions and waist-shaped sheets with long axes arranged in the left and right directions.

[0047] As a specific example, four front limit rods are arranged in sequence from left to right, two front limit rods located on the left and right sides of the four front limit rods are located further back than the two front limit rods located in the middle of the four front limit rods, and the two first front limit rods 4 are located between the two second front limit rods 3.

Further, a stabilizing arm 11 can be fixedly mounted on the fifth mounting seat 9, and the end of the stabilizing arm 11 is connected to the upper end of the first core rod 401. The provision of the stabilizing arm 11 can ensure the stability of the first front limit rod 4.

Moreover, the sheet member guiding device proposed in the present application has good anti-jamming performance for circular sheet 100, elliptical sheet 200 and waist-shaped sheet 300. The sheet member guiding device proposed in the present application has the characteristics of wide application range.

[0052] The present invention also provides a sheet-like piece stacking device, comprising any of the sheet-like piece guiding devices described above.
