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

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

[0004] In addition, there may also be a separation structure that separates continuous sheets such as biscuits by vertically moving the separation arm up and down. However, the separation 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 different lengths of continuous biscuits and other sheets on each input device, the entire sheet sorting device needs to be shut down, causing other workstations to be unusable and low production efficiency.

[0014] Furthermore, the cache power device is gears meshing with each other, and one of the cache power devices is a power wheel.

[0015] The two buffer support arms can be opened synchronously to ensure that the sheets fall vertically after separation.

[0016] Furthermore, the cache assembly also includes a rack and a linear power device installed on the frame, the linear power device is connected to the rack, one of the cache power devices is meshed with the rack, and the other of the cache power devices is provided with a yielding opening.

DETAILED DESCRIPTION

[0044] The technical solution of the present invention will be described below in conjunction with the accompanying drawings of the present invention.

[0045] 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.

[0046] The sheet sorting device of the present invention comprises an input device 8 and a frame 7. The input device 8 is used to convey continuous sheets W1 [each sheet is continuously and mutually attached] to the partition assembly 1, and the input device 8 can be a power belt or other power device. The frame 7 is used to install various parts of the sheet sorting device, wherein the part of the frame 7 used to install the input device 8 is not shown.

[0047] Preferably, the input device 8 comprises an input guide rail 81 and a linear vibrator 82 disposed on the input guide rail 81. The continuous sheet W1 can be continuously moved by means of vibration to ensure that each sheet W1 is fitted together.

[0048] Furthermore, the input guide rail 81 partially overlaps with the buffer support arm 21 when viewed from above, and the input guide rail 81 is higher than the buffer support arm 21 or fits with the buffer support arm 21. Usually, the input guide rail 81 is slightly higher than the buffer support arm 21, so that the continuous sheet W1 on the input guide rail 81 has a height difference with the buffer support arm 21, and when the partition arm 11 is at the lower limit position, it is convenient for the partition arm 11 to abut against the end of the continuous sheet W1 on the input device 8.

[0049] The sheet object sorting device of the invention further comprises a partition component 1 and a buffer component 2 mounted on a frame 7 .

[0050] The partition assembly 1 is provided with a partition arm 11 which 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].

[0051] 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, the cache support arm 21 is connected by 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 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 and the end of the cache support arm 21 away from the input guide rail 81 are lower, so that the cache support arm 21 is set at an angle.

[0052] 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 arms 22, and the other ends of the cache swing arms 22 are respectively provided with cache power devices 23. Fig.11As shown, when the continuous sheet W1 is in the shape of a disk, it can be stably placed on the two buffer arms 21. The buffer power device 23 rotates and drives the horizontal distance between the two buffer swing arms 22 to increase until it is larger than the diameter of the separated sheet W2. The separated sheet W2 falls from the buffer arm 21 to the output device 9. At the same time, the vertical position of the buffer arm 21 becomes higher, which will not block the movement of the separated sheet W2 on the output device 9, so that the falling distance H can be smaller [theoretically zero] and prevent the separated sheet W2 from falling and being damaged. Usually, the buffer arm 21 is columnar.

[0053] Preferably, the cache power device 23 is a gear meshing with each other, and one of the cache power devices 23 is a power wheel [i.e., a gear with rotational power, such as a gear driven by the rotation output end of the motor by a reduction gear]. The two cache swing arms 22 can be rotated synchronously, so that the two cache supporting arms 21 can be opened synchronously to ensure that the sheet W2 falls vertically after separation.

[0054] Preferably, the cache assembly 2 further includes a rack 232 and a linear power device 233 mounted on the frame 7, the linear power device 233 is connected to the rack 232, one of the cache power devices 23 is meshed with the rack 232, and the other of the cache power devices 23 is provided with a clearance opening 231 so that the other of the cache power devices 23 is not meshed with the rack 232. The linear power device 233 is a linear power device such as a cylinder. When there are multiple cache assemblies 2, one linear power device 233 can synchronously drive multiple cache assemblies 2, which is conducive to reducing costs.

[0055] 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 .

[0056] When the partition arm 11 is located 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 of the continuous sheet W1 on the input device 8 in the direction from input to output].

[0057] When the partition arm 11 is located at the upper limit position, the bottom end of the partition arm 11 is higher than the end of the continuous sheet W1 on the input device 8 , so that the partition arm 11 does not abut against the end of the continuous sheet W1 on the input device 8 .

[0058] Usually, the sheet sorting device of the present invention also includes an output device 9 arranged below the buffer support arm 21. Usually, the output device 9 is a flat plate with a relatively smooth surface, and an array of movable output baffles 91 are arranged above the output device 9; the output baffles 91 usually move vertically to the paper surface, hold the separated sheet W2 falling from the buffer support arm 21, and output the separated sheet W2 to the next process, such as the bagging process; a tray can also be placed between the output baffles 91 [not shown in the accompanying drawings, the tray is usually a box with a semi-cylindrical or square cross-section and an open top, usually made of transparent plastic, and is bagged together with biscuits and other sheet materials], and after the separated sheet W2 falling from the buffer support arm 21 falls into the tray, the output baffles 91 hold the tray and the separated sheet W2 and move them to the next process, such as the bagging process. The output device 9 can also be a power belt, etc.

[0059] The working principle of the sheet sorting device of the present invention is: before use, the sheets [not shown in the drawings] of 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.

[0060] When in 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.

[0061] 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 [i.e., the last sheet W1 on the input device 8 in the direction from input to output], so that the partition arm 11 stays on the input device 8, and the continuous sheet W1 on the buffer support arm 21 and the continuous sheet W1 on the input device 8 are separated by the partition 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, so that the separated sheet W2 on the buffer support arm 21 falls from the buffer support arm 21, falls on the output device 9, and is output to the next process.

[0062] By repeating the above process, the continuous sheet W1 can be continuously separated into separated sheets W2.

[0063] It can be seen from the above that the sheet sorting device of the present invention can automatically and continuously separate the continuous sheets W1 into separated sheets W2, so as to facilitate the packaging of the separated sheets W2.

[0064] Furthermore, the sheet sorting device of the present invention further comprises a blocking assembly 4 mounted on the frame 7, the blocking assembly 4 comprising 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 separated sheet W2 clamped by the blocking arm 41 can prevent the sheet from falling down under the action of its own weight. Figure 7 As shown, the top of the sheet rotates downward, resulting in inaccurate counting of the separated sheet W2.

[0065] Furthermore, the material blocking assembly 4 also includes an adjusting device 42 connected to the material blocking arm 41. The adjusting 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, which is suitable for different packaging requirements and has high versatility.

[0066] Furthermore, the material blocking assembly 4 also includes a synchronous belt 421 and a synchronous wheel 422 driving the synchronous belt 421; the adjusting device 42 is a crossbeam connected to the synchronous belt 421. Usually, one of the synchronous wheels 422 is driven by a stepper motor [not shown in the drawings], and the synchronous wheel 422 drives the synchronous belt 421 to move linearly, so that the material blocking arm 41 moves horizontally. When there are multiple cache assemblies 2 and material blocking arms 41, the stepper motor [not shown in the drawings] can synchronously drive each material blocking arm 41 to move more closely, so that the length of the separated sheet W2 output by each cache assembly 2 can be the same; and it is beneficial to reduce costs.

[0067] like Figure 8 As shown, during the process of the partition arm 11 moving from the lower 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 located at the upper limit position and when the separator arm 11 is located at the lower limit position, the distance in the horizontal direction 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 process of the separator arm 11 moving from the lower 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 abuts 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, thereby preventing the bottom end of the separator arm 11 from directly abutting against a certain sheet and crushing the sheet.

[0068] Furthermore, in the process of the separator arm 11 moving from the lower limit position to the lower limit position, the separator arm inclination angle β between the separator arm 11 and the vertical plane decreases. In the process of the separator arm 11 moving from the lower 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 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, so that the bottom end of the separator arm 11 is easier to insert 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 with 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.

[0069] 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 partition mounting block 12 and the first rocker arm 13 is the point X [when viewed from the side], the axis of the partition mounting block 12 and the second rocker arm 14 is the 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 the point W [when viewed from the side [when viewed from the side], 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 in the process of the separator arm 11 moving from the lower 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. The structure is relatively simple and has low cost.

[0070] Furthermore, the sheet sorting device of the present invention further includes a separation drive assembly 3, which is provided with a separation drive arm 31 that can swing back and forth, and the first rocker arm 13 extends outward to form a first power end 131, and the separation drive arm 31 is connected to the first power end 131, so that the first rocker arm 13 can swing back and forth. The separation drive assembly 3 can be a reduction motor, and the separation drive assembly 3 can swing back and forth through the reciprocating swing of the output end of the reduction motor [realized by a conventional swinging structure].

[0071] Furthermore, the partition assembly 1 further comprises a positioning hook 15 mounted on the frame 7, the positioning hook 15 is provided with a positioning slot 151, and 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, so as to ensure the accuracy of the partition arm 11 at the lower limit position.

[0072] 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 of which can swing back and forth in a linked manner, 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, and 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 it is necessary to stop the input device 8 and the 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 sheets makes the length of the continuous sheets W1 longer], which is conducive to improving production efficiency.

[0073] Furthermore, the partition drive assembly 3 also includes a partition assembly 1 provided with a partition arm 11, and 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 has a tendency to move toward the upper limit position. Usually, 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, and when the partition arm 11 is located 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 located at the lower limit position to abut against the end of the continuous sheet W1 on the input guide rail 81, and the continuous sheet W1 on the input guide rail 81 can be prevented from continuing to move forward.

[0074] Preferably, the abutment member 36 is a pre-stretched single-acting cylinder or an elastic member such as a spring, and the two ends of the abutment member 36 are respectively hinged to the frame 7 and the partition assembly 1 [first power end 131], so that the partition arm 11 tends to move toward the upper limit position. Preferably, it is a pre-stretched single-acting cylinder.

[0075] As an embodiment, the partition drive assembly 3 also includes a partition input arm 32 and a clutch 33 arranged on the frame 7. The partition drive arm 31 and the partition input arm 32 are fixedly connected to the two ends of the clutch 33 respectively, and the partition input arm 32 can swing back and forth.

[0076] Furthermore, the partition drive assembly 3 further includes a swing arm 34, one end of which is hinged with a swing connection arm 341, and the other end of the swing arm 34 is fixedly provided with a swing power shaft 342 hinged with the frame 7, the swing power shaft 342 can reciprocate, and the swing connection arm 341 is hinged with the partition input arm 32. One swing power shaft 342 can make the partition drive arm 31 reciprocate in linkage, without the need for even multiple reciprocating swing mechanisms, which is conducive to reducing costs.

[0077] 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 with 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, so that the swing power shaft 342 can reciprocate. The swing drive device 35 is a unidirectional rotating power device such as a motor, and the swing power shaft 342 can reciprocate without a complex motor control device [such as a motor driver, etc.], which is conducive to reducing costs.

[0078] Furthermore, the clutch 33 has an electric control structure [a conventional electric control structure in the prior art], and the clutch 33 is electrically connected to an electric control device [such as a PLC, an industrial computer, etc., not shown in the drawings].
