Description

Technical Field

[0001] The invention belongs to the technical field of packaging machinery, and in particular relates to a sheet separation structure. Background Art

[0002] In the production process of biscuits and other sheet materials, it is usually necessary to sort the biscuits and other sheet materials into specified quantities to form separated biscuits and other sheet materials, and then carry out the next step of packaging, such as putting them into biscuit boxes or biscuit bags.

[0003] The traditional method of sorting biscuits and other sheet materials is to rely on manual labor, which is time-consuming and labor-intensive.

[0004] In addition, a separating structure can be provided in which a separating arm moves vertically up and down to separate sheets such as continuous biscuits. However, the separating arm that moves vertically up and down may directly support the top of sheets such as biscuits, causing the sheets such as biscuits to be damaged.

[0005] Furthermore, in a conventional sheet sorting device, when an operator forgets to place a sheet, resulting in the lengths of consecutive biscuits and other sheets on each input device being different, the entire sheet sorting device needs to be shut down, causing other workstations to be unusable and low production efficiency. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a sheet separation structure, which can make the bottom end of the separation arm easier to insert between the end of the continuous sheet and the head end of the continuous sheet on the cache support arm, preventing the bottom end of the separation arm from directly abutting against a certain sheet and crushing the sheet.

[0007] The detailed technical solution adopted by the present invention is: a sheet separation structure, which includes an input device, a frame and a separation component provided with a separation arm, and is characterized in that:

[0008] During the movement of the partition arm from the upper limit position to the lower limit position, the bottom end of the partition arm moves toward the input device.

[0009] Furthermore, during the process of the partition arm moving from the upper limit position to the lower limit position, the partition arm inclination angle β between the partition arm and the vertical plane decreases.

[0010] The bottom end of the separation arm can be easily inserted between the end of the continuous sheet and the head end of the continuous sheet on the buffer support arm, and the sheet in contact with the separation arm can be prevented from being scratched by the bottom end of the separation arm.

[0011] Furthermore, the partition assembly includes a partition arm and a partition mounting block fixedly connected to the partition arm; the partition assembly also includes a first rocker arm and a second rocker arm; the two ends of the partition mounting block are hinged to the first rocker arm and the second rocker arm respectively; the other end of the first rocker arm and the other end of the second rocker arm are hinged to the frame respectively; the first rocker arm and / or the second rocker arm can swing back and forth; a rocker arm angle α is set between the first rocker arm and the second rocker arm, and the second arm length C of the second rocker arm is less than or equal to the first arm length B of the first rocker arm.

[0012] The structure is relatively simple and the cost is low.

[0013] Furthermore, it also includes a separation drive component, which is provided with a separation drive arm that can swing back and forth, a first rocker arm extends outward to form a first power end, and the separation drive arm is connected to the first power end.

[0014] Furthermore, the partition assembly also includes a positioning hook installed on the frame, the positioning hook is provided with a positioning slot, and when the partition arm is located at the lower limit position, the partition mounting block abuts against the inner wall of the positioning slot.

[0015] The accuracy of the separation arm when it is at the lower limit position can be guaranteed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1) The bottom end of the partition arm can be more easily inserted between the end of the continuous sheet and the head end of the continuous sheet on the buffer support arm, preventing the bottom end of the partition arm from directly abutting against a sheet and crushing the sheet.

[0018] 2) The bottom end of the separation arm is easier to insert between the end of the continuous sheet and the head end of the continuous sheet on the buffer support arm, and the sheet in contact with the separation arm is prevented from being scratched by the bottom end of the separation arm.

[0019] 3) The structure is relatively simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0036] It should be noted that if Figure 8 The vertical direction shown is the vertical direction described below, such as Figure 8 The directions shown in the horizontal plane are the horizontal directions described below.

[0037] The sheet object sorting device of the present invention includes an input device 8 and a frame 7. The input device 8 is used to convey a continuous stream of sheet objects W1 to the separator assembly 1, wherein each sheet object is continuously and closely attached to each other. The input device 8 can be a powered belt or other powered device. The frame 7 is used to mount the various components of the sheet object sorting device. The portion of the frame 7 where the input device 8 is mounted is not shown.

[0038] Preferably, the input device 8 includes an input guide rail 81 and a linear vibrator 82 disposed on the input guide rail 81. Vibration can be used to continuously move the continuous sheets W1 to ensure that the sheets are fitted together.

[0039] Furthermore, when viewed from above, the input guide rail 81 partially overlaps with the buffer support arm 21, and the input guide rail 81 is higher than or in contact with the buffer support arm 21. Typically, the input guide rail 81 is slightly higher than the buffer support arm 21, so that a height difference exists between the continuous sheet W1 on the input guide rail 81 and the buffer support arm 21. When the separator arm 11 is at the lower limit position, the separator arm 11 facilitates contact with the end of the continuous sheet W1 on the input device 8.

[0040] The sheet object sorting device of the invention further includes a partition assembly 1 and a buffer assembly 2 mounted on a frame 7 .

[0041] The partition assembly 1 is provided with a partition arm 11 that can move up and down, that is, before and after the partition arm 11 moves up and down, the bottom end of the partition arm 11 is offset in the vertical direction, but before and after the partition arm 11 moves up and down, each point on the partition arm 11 may be offset in the horizontal direction [for example, by connecting the partition arm 11 with a linear device inclined relative to the vertical direction, or by the partition assembly 1 of the present invention], or there may be no offset [for example, by connecting the partition arm 11 with a linear power device such as a cylinder to realize the up and down linear movement of the partition arm 11].

[0042] The cache assembly 2 includes at least one cache support arm 21 that can move horizontally, that is, before and after the cache support arm 21 moves horizontally, the cache support arm 21 is offset in the horizontal direction, but before and after the cache support arm 21 moves horizontally, each point on the cache support arm 21 may be offset in the vertical direction [for example, achieved by the cache assembly 2 of the present invention], or there may be no offset [for example, by connecting the cache support arm 21 through a linear power device such as a cylinder to achieve horizontal linear movement of the cache support arm 21]. The cache support arm 21 can be plate-shaped, so that one cache support arm 21 can hold up a continuous sheet W1, or it can be of other shapes. Usually, the cache support arm 21 is set horizontally. Of course, the cache support arm 21 can also be set at an angle, for example, the end of the cache support arm 21 close to the input guide rail 81 is lower than the end of the cache support arm 21 away from the input guide rail 81, so that the cache support arm 21 is set at an angle.

[0043] Preferably, the cache assembly 2 further includes two cache swing arms 22, there are two cache supporting arms 21 with a gap between them, the cache supporting arms 21 are respectively connected to one end of the cache swing arm 22, and the other end of the cache swing arm 22 is respectively provided with a cache power device 23. Figure 11As shown, when the continuous sheet W1 is disc-shaped, it can be stably placed on the two buffer arms 21. The buffer power device 23 rotates, driving the two buffer swing arms 22 to increase the horizontal distance between them until it is larger than the diameter of the separated sheet W2. The separated sheet W2 falls from the buffer arms 21 onto the output device 9. At the same time, the vertical position of the buffer arms 21 is raised, which does not hinder the movement of the separated sheet W2 on the output device 9. This keeps the falling distance H short (theoretically zero) and prevents the separated sheet W2 from falling and being damaged. Typically, the buffer arms 21 are cylindrical.

[0044] Preferably, the buffer power device 23 is a meshing gear, one of which is a power wheel (i.e., a gear with rotational power, such as a gear driven by a reduction gear from the rotational output of a motor). This allows the two buffer swing arms 22 to rotate synchronously, thereby causing the two buffer support arms 21 to open synchronously, ensuring that the sheet W2 falls vertically after separation.

[0045] Preferably, the cache assembly 2 further includes a rack 232 and a linear actuator 233 mounted on the frame 7. The linear actuator 233 is connected to the rack 232. One of the cache actuators 23 engages with the rack 232, while the other of the cache actuators 23 is provided with a clearance opening 231 to prevent the other cache actuator 23 from engaging with the rack 232. The linear actuator 233 can be a linear actuator such as a cylinder. If multiple cache assemblies 2 are provided, a single linear actuator 233 can synchronously drive multiple cache assemblies 2, thereby reducing costs.

[0046] The output end of the input device 8 is connected to the input end of the buffer support arm 21 , so that the continuous sheet W1 can be transported from the input device 8 to the buffer support arm 21 .

[0047] When the partition arm 11 is at the lower limit position, the partition arm 11 abuts against the end of the continuous sheet W1 on the input device 8 [ie, the last sheet W1 on the input device 8 in the direction from input to output].

[0048] When the separating arm 11 is at the upper limit position, the bottom end of the separating arm 11 is higher than the end of the continuous sheet W1 on the input device 8 , so that the separating arm 11 does not abut against the end of the continuous sheet W1 on the input device 8 .

[0049] Typically, the sheet sorting device of the present invention further includes an output device 9 disposed below the buffer support arm 21. Typically, the output device 9 is a flat plate with a relatively smooth surface, and an array of movable output bars 91 is disposed above the output device 9. The output bars 91 typically move perpendicular to the paper surface, holding the separated sheets W2 that fall from the buffer support arm 21, and outputting the separated sheets W2 to the next process, such as the bagging process. Alternatively, a tray (not shown in the accompanying drawings, but typically a box with a semi-cylindrical or square cross-section and an open top, typically made of transparent plastic, and bagged along with biscuits and other sheet materials) may be placed between the output bars 91. After the separated sheets W2 that fall from the buffer support arm 21 fall onto the tray, the output bars 91 hold the tray and the separated sheets W2, moving them to the next process, such as the bagging process. The output device 9 may also be a powered belt, etc.

[0050] The working principle of the sheet sorting device of the present invention is as follows: before use, sheets [not shown in the drawings] from the previous process [such as the sheet concentration process] are input from the input end of the input device 8 to form continuous sheets W1 on the input device 8.

[0051] During use, the separator arm 11 moves up and down. When the separator arm 11 is at the upper limit position, the bottom end of the separator arm 11 is higher than the end of the continuous sheet W1 on the input device 8, so that the separator arm 11 does not resist the end of the continuous sheet W1 on the input device 8, and the continuous sheet W1 on the input device 8 continues to move to the cache support arm 21.

[0052] When the separator arm 11 is at its lower limit, it abuts the end of the continuous sheet W1 on the input device 8 (i.e., the last sheet W1 on the input device 8, moving from input to output), causing the separator arm 11 to remain on the input device 8. The continuous sheet W1 on the buffer support arm 21 and the continuous sheet W1 on the input device 8 are separated by the separator arm 11, so that the continuous sheet W1 on the buffer support arm 21 forms the separated sheet W2 on the buffer support arm 21. At the same time, the buffer support arm 21 moves horizontally, causing the separated sheet W2 on the buffer support arm 21 to fall from the buffer support arm 21 onto the output device 9 and be output to the next process.

[0053] By repeating the above process, the continuous sheet W1 can be continuously separated into separated sheets W2.

[0054] As can be seen from the above, the sheet sorting device of the present invention can automatically and continuously separate the continuous sheet W1 into separated sheet W2, which is convenient for packaging the separated sheet W2.

[0055] Furthermore, the sheet sorting device of the present invention further includes a blocking assembly 4 mounted on the frame 7, the blocking assembly 4 including a blocking arm 41, the blocking arm 41 being located above the buffer support arm 21 and having a gap between the blocking arm 41 and the output end of the input device 8. The continuous sheet W1 on the input device 8 and the blocking arm 41 clamp the separated sheet W2, which can prevent the sheet from falling under the action of its own weight [i.e. Figure 7 As shown, the top of the sheet rotates downward, resulting in inaccurate counting of the separated sheet W2.

[0056] Furthermore, the material blocking assembly 4 also includes an adjustment device 42 connected to the material blocking arm 41. The adjustment device 42 is a linear power device such as a cylinder. The material blocking arm 41 drives the material blocking arm 41 to move parallel to the buffer support arm 21, so that the length of the separated sheet W2 on the buffer support arm 21 can be adjusted as needed, adapting to different packaging requirements and having high versatility.

[0057] Furthermore, the material blocking assembly 4 also includes a synchronous belt 421 and a synchronous pulley 422 that drives the synchronous belt 421; the adjustment device 42 is a crossbeam connected to the synchronous belt 421. Typically, one of the synchronous pulleys 422 is driven by a stepper motor [not shown in the drawings], which drives the synchronous belt 421 in linear motion, causing the material blocking arm 41 to translate. When there are multiple cache assemblies 2 and multiple material blocking arms 41, the stepper motor [not shown in the drawings] can synchronously drive each material blocking arm 41 to move more closely, ensuring that the length of the separated sheet W2 output by each cache assembly 2 is the same, and this is beneficial for reducing costs.

[0058] like Figure 8 As shown, during the process of the partition arm 11 moving from the upper limit position to the lower limit position, the bottom end of the partition arm 11 moves toward the input guide rail 81. When the separator arm 11 is at the upper limit position and when the separator arm 11 is at the lower limit position, the horizontal distance of the bottom end of the separator arm 11 is the horizontal offset distance γ, and the horizontal offset distance γ gradually decreases during the movement of the separator arm 11 from the upper limit position to the lower limit position; when the bottom end of the separator arm 11 contacts the end of the continuous sheet W1 on the input guide rail 81 [the input guide rail 81 is slightly higher than the cache support arm 21], the bottom end of the separator arm 11 horizontally presses against the end of the continuous sheet W1 on the input guide rail 81, so that a gap is formed between the end of the continuous sheet W1 on the input guide rail 81 and the head end of the continuous sheet W1 on the cache support arm 21, so that the bottom end of the separator arm 11 can be more easily inserted between the end of the continuous sheet W1 and the head end of the continuous sheet W1 on the cache support arm 21, preventing the bottom end of the separator arm 11 from directly pressing against a certain sheet and crushing the sheet.

[0059] Furthermore, during the movement of the separator arm 11 from the upper limit position to the lower limit position, the separator arm inclination angle β between the separator arm 11 and the vertical plane decreases. During the movement of the separator arm 11 from the upper limit position to the lower limit position, the separator arm inclination angle β gradually decreases, and the angle between the separator arm 11 and the vertically arranged sheet and the sheet also gradually decreases, so that the contact area between the bottom end of the separator arm 11 and the sheet gradually increases until it is the largest when the separator arm 11 is at the lower limit position. When the bottom end of the separator arm 11 contacts the continuous sheet W1 on the input guide rail 81, the separator arm inclination angle β is large, making it easier for the bottom end of the separator arm 11 to be inserted between the end of the continuous sheet W1 and the head end of the continuous sheet W1 on the buffer support arm 21. When the separator arm 11 is at the lower limit position, the sheet fits against the separator arm 11, which can prevent the sheet in contact with the separator arm 11 from being scratched by the bottom end of the separator arm 11.

[0060] As an embodiment, the partition assembly 1 includes a partition arm 11 and a partition mounting block 12 fixedly connected to the partition arm 11; the partition assembly 1 also includes a first rocker arm 13 and a second rocker arm 14; the two ends of the partition mounting block 12 are respectively hinged to the first rocker arm 13 and the second rocker arm 14; the axis of the hinge connection between the partition mounting block 12 and the first rocker arm 13 is point X [when viewed from the side], the axis of the hinge connection between the partition mounting block 12 and the second rocker arm 14 is point Y [when viewed from the side], and the partition arm length A of the partition mounting block 12 is the straight line XY; the other end of the first rocker arm 13 and the other end of the second rocker arm 14 are respectively hinged to the frame 7; the first rocker arm 13 and / or the second rocker arm 14 can swing back and forth [i.e., reciprocate along a circular arc]; that is, the first rocker arm 13 can revolve around point W [when viewed from the side [When viewed from the side], the first rocker arm 13 can reciprocate and / or the second rocker arm 14 can reciprocate around point W [when viewed from the side]; the axis at which the other end of the first rocker arm 13 is hinged to the frame 7 is point W [when viewed from the side], and the first arm length B of the first rocker arm 13 is a straight line XW; the axis at which the other end of the second rocker arm 14 is hinged to the frame 7 is point Z [when viewed from the side]; the second arm length C of the second rocker arm 14 is a straight line YZ; a rocker arm angle α is set between the first rocker arm 13 and the second rocker arm 14, and the second arm length C of the second rocker arm 14 is less than or equal to the first arm length B of the first rocker arm 13, so that when the separator arm 11 moves from the upper limit position to the lower limit position, the separator arm inclination angle β between the separator arm 11 and the vertical plane decreases, and the bottom end of the separator arm 11 moves toward the input guide rail 81. This structure is relatively simple and has low cost.

[0061] Furthermore, the sheet object sorting device of the present invention further includes a separation drive assembly 3, which is provided with a reciprocating separation drive arm 31. The first rocker arm 13 extends outward to form a first power end 131. The separation drive arm 31 is connected to the first power end 131, thereby enabling the first rocker arm 13 to reciprocate. The separation drive assembly 3 can be a reduction motor, and the reciprocating swing of the output end of the reduction motor (achieved by a conventional swinging structure) enables the separation drive assembly 3 to reciprocate.

[0062] Furthermore, the partition assembly 1 further includes a positioning hook 15 mounted on the frame 7. The positioning hook 15 is provided with a positioning slot 151. When the partition arm 11 is at the lower limit position, the partition mounting block 12 abuts against the inner wall of the positioning slot 151. This ensures the accuracy of the partition arm 11 at the lower limit position.

[0063] The sheet sorting device of the present invention also includes a separation drive assembly 3, which is provided with at least two separation drive arms 31. Each separation drive arm 31 can be linked to swing back and forth, or can be stopped individually. Usually, there are more than two input devices 8 and separation assemblies 1, and they are respectively opposite to each separation drive arm 31. The separation drive arm 31 is connected to the first power end 131 through a power connecting arm 139. When the lengths of the continuous sheets W1 on each input device 8 are different [for example, the sheets on the input device 8 are manually placed and the operator forgets to place the sheets], and when it is necessary to stop the input device 8 and separation assembly 1 of a certain station separately, one or more separation drive arms 31 can be stopped separately, so that the length of the continuous sheets W1 on the input device 8 can be adjusted without stopping the entire sheet sorting device [for example, putting in a sheet will make the length of the continuous sheet W1 longer], which is beneficial to improving production efficiency.

[0064] Furthermore, the partition drive assembly 3 also includes a partition assembly 1 provided with a partition arm 11. The partition drive assembly 3 also includes a supporting member 36 provided on the frame 7. One end of the supporting member 36 is connected to the partition assembly 1, so that the partition arm 11 tends to move toward the upper limit position. Typically, the partition assembly 1 also includes a positioning hook 15 installed on the frame 7. The positioning hook 15 is provided with a positioning groove 151. When the partition arm 11 is at the lower limit position, the partition mounting block 12 abuts against the inner wall of the positioning groove 151. When the partition drive arm 31 stops alone, it can ensure that the partition arm 11 is at the lower limit position and abuts against the end of the continuous sheet W1 on the input guide rail 81, thereby preventing the continuous sheet W1 on the input guide rail 81 from continuing to move forward.

[0065] Preferably, the abutment member 36 is a pre-extended single-acting cylinder or a spring or other elastic member. The two ends of the abutment member 36 are respectively hinged to the frame 7 and the first power end 131 of the partition assembly 1, thereby causing the partition arm 11 to move toward the upper limit position. A pre-extended single-acting cylinder is preferred.

[0066] As an embodiment, the separation drive assembly 3 also includes a separation input arm 32 and a clutch 33 arranged on the frame 7. The separation drive arm 31 and the separation input arm 32 are fixedly connected to the two ends of the clutch 33 respectively, and the separation input arm 32 can swing back and forth.

[0067] Furthermore, the partition drive assembly 3 also includes a swing arm 34, one end of which is hingedly connected to a swing connecting arm 341. The other end of the swing arm 34 is fixedly provided with a swing power shaft 342 hingedly connected to the frame 7. The swing power shaft 342 can reciprocate. The swing connecting arm 341 is hingedly connected to the partition input arm 32. A single swing power shaft 342 can cause the partition drive arm 31 to swing back and forth in a coordinated manner, eliminating the need for multiple reciprocating swing mechanisms, which helps reduce costs.

[0068] Furthermore, the partition drive assembly 3 also includes a swing drive device 35, which includes a swing power device 351, an eccentric device 352, and an eccentric arm 353 having an eccentric arm slot 354. The eccentric device 352 is fixedly connected to the rotation output end of the swing power device 351, and the eccentric end of the eccentric device 352 is embedded in the eccentric arm 353. The eccentric arm 353 is fixedly connected to the swing power shaft 342, thereby enabling the swing power shaft 342 to rotate back and forth. The swing drive device 35 is a unidirectional rotating power device such as a motor. It can achieve reciprocating rotation of the swing power shaft 342 without requiring a complex motor control device (such as a motor driver), which helps reduce costs.

[0069] Furthermore, the clutch 33 has an electronic control structure (conventional electronic control structures in the prior art). The clutch 33 is electrically connected to an electronic control device (such as a PLC, industrial computer, etc., not shown). Typically, the input device 8 is equipped with a sensor that senses the length of the continuous sheet W1 on the input guide rail 81. This sensor is electrically connected to the electronic control device (such as a PLC, industrial computer, etc., not shown) to automatically stop the drive arm 31 from separating according to the length of the continuous sheet W1 on the input guide rail 81.
