Description

Technical Field

[0001] The invention relates to the technical field of biscuit production, and in particular to a horizontal row spacing adjustment device. Background Art

[0002] When compressed biscuits come out of the forming machine, they are in a compact and compressed square shape, and then they need to be vacuum packed in a vacuum aluminum foil bag to effectively maintain the crispy taste of the biscuits. Before packaging, the compressed biscuits need to be adjusted to a uniform posture and arranged neatly so that they can be quickly fed into the vacuum packaging machine.

[0003] At present, after the compressed biscuits are neatly arranged horizontally at the end of the conveyor belt, a biscuit picking device picks up a certain amount of biscuits from the rows of biscuits and puts them into the vacuum packaging machine for batch packaging. When the picking device picks up biscuits, it picks up a certain amount of biscuits according to the number of rows in vacuum packaging. When picking up, the biscuits are placed side by side and close to each other, and when packaging, a suitable gap must be left between the biscuits in the same row so that there is space for heat sealing the upper and lower films of the packaging bag. Therefore, the biscuits placed in rows on the lower film of the packaging bag by the picking device need to be further spaced apart before the next step of vacuum heat sealing of the upper and lower films can be carried out.

[0004] However, most of the existing picking devices have simple structures, and the placement and spacing of biscuits are mostly completed in steps, which reduces the biscuit production efficiency. Therefore, in order to solve the above technical problems, a horizontal row spacing adjustment device is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes a device for adjusting the horizontal row spacing, which facilitates the synchronous separation of biscuits during the process of placing the biscuits into the lower film of the packaging bag, thereby improving the biscuit production efficiency.

[0042] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0043] See also Figures 1 to 3 In one embodiment, the biscuit picking device includes a horizontal row spacing adjustment device, and the horizontal row spacing adjustment device includes a frame 10, a moving mechanism, a grabbing mechanism, an excitation mechanism and a spacing adjustment mechanism.

[0044] The grabbing mechanism includes a guide member 20 and multiple grabbing components. The guide member 20 is mounted on the moving mechanism. The multiple grabbing components are slidably arranged in an array on the guide member 20. The excitation mechanism is mounted on the guide member 20. The excitation mechanism is connected to the multiple grabbing components. The excitation mechanism is used to drive the multiple grabbing components to contact or move away from the biscuits. The spacing adjustment mechanism is connected to the frame 10, the moving mechanism and the multiple grabbing components. The spacing adjustment mechanism is used to convert the movement of the moving mechanism into the spacing adjustment of the multiple grabbing components. When the grabbing components grab the biscuits and move toward the lower film of the packaging bag, the multiple grabbing components are driven to separate at intervals. When the grabbing components are reset, the multiple grabbing components are driven to close together.

[0045] In the above embodiment, after the excitation mechanism is controlled to drive the multiple groups of grabbing components to contact the biscuits, the multiple groups of grabbing components are controlled to grab the biscuits neatly arranged laterally at the end of the conveyor belt, and then the moving mechanism is controlled to drive the multiple groups of grabbing components to drive the biscuits to move toward the lower film of the packaging bag. While the biscuits are moving toward the lower film of the packaging bag, the spacing adjustment mechanism drives the multiple groups of grabbing components to separate at intervals, and then the multiple groups of grabbing components are controlled to cancel the grabbing of the biscuits, so that the biscuits neatly arranged laterally at the end of the conveyor belt can be separated at intervals and placed on the lower film of the packaging bag, which is convenient for synchronously completing the spacing of the biscuits during the process of placing the biscuits on the lower film of the packaging bag, thereby improving the biscuit production efficiency. After the biscuits are placed on the lower film of the packaging bag, the moving mechanism is controlled to drive the multiple groups of grabbing components to reset, and the spacing adjustment mechanism drives the multiple groups of grabbing components to close together. At this time, the biscuits neatly arranged laterally at the end of the conveyor belt can be grabbed again.

[0046] See also Figure 1 In one embodiment, the moving mechanism includes a mounting block 30 and a first driving assembly; the mounting block 30 is horizontally and longitudinally slidably arranged on the frame 10, one end of the guide member 20 is connected to the mounting block 30, the first driving assembly connects the frame 10 and the mounting block 30, and the first driving assembly is used to drive the mounting block 30 to slide.

[0047] Please join us Figure 3 Specifically in the above embodiment, the first driving assembly includes a first screw rod 302 and a first motor 303. A first slide groove 102 is opened on the frame 10. The top end of the mounting block 30 is horizontally and longitudinally slidably arranged in the first slide groove 102. The first screw rod 302 is horizontally and longitudinally arranged, and is rotatably arranged in the first slide groove 102, and is threadedly connected to the mounting block 30. The first motor 303 is arranged on the frame 10, and the output end is coaxially connected to the first screw rod 302.

[0048] In the above embodiment, the first motor 303 is controlled to drive the first screw 302 to rotate. The first screw 302 rotates and cooperates with the thread of the mounting block 30 to drive the mounting block 30 to move. The movement of the mounting block 30 can drive the guide member 20 to move. The movement of the guide member 20 can drive multiple groups of grabbing components to move, thereby facilitating driving multiple groups of grabbing components to drive the grabbed biscuits to move toward the lower film of the packaging bag. The first motor 303 is controlled to drive the first screw 302 to rotate in the opposite direction. The first screw 302 rotates in the opposite direction and cooperates with the thread of the mounting block 30 to drive the mounting block 30 to move in the opposite direction. The mounting block 30 moves in the opposite direction to drive the guide member 20 to move in the opposite direction. The guide member 20 moves in the opposite direction to drive multiple groups of grabbing components to move in the opposite direction, thereby facilitating driving multiple groups of grabbing components to reset and grab biscuits again.

[0049] See also Figure 1 , Figures 4 to 8 In one embodiment, the grabbing assembly includes a mounting rod 201, a negative pressure suction cup 202 and a telescopic assembly; a connecting sleeve 203 is provided on the mounting rod 201, and the connecting sleeve 203 is horizontally and laterally slidably sleeved on the guide member 20, and the negative pressure suction cup 202 is arranged at the bottom of the mounting rod 201 and can be raised and lowered through the telescopic assembly. The excitation mechanism is connected to the telescopic assembly to drive the telescopic assembly to extend or contract, so that the negative pressure suction cup 202 descends to contact the biscuits or rises away from the biscuits. The negative pressure suction cup 202 is connected to the negative pressure device through a first connecting pipe 2021.

[0050] The telescopic assembly includes a piston 204 and a piston rod 205; a piston chamber 2011 is opened in the mounting rod 201, and the piston 204 is sealed and slidably arranged in the piston chamber 2011 along the vertical direction. A piston rod 205 is vertically arranged at the bottom end of the piston 204, and the bottom end of the piston rod 205 passes through the bottom end of the mounting rod 201 and is connected to the negative pressure suction cup 202. An air guide hole 2012 connected to the inner wall of the connecting sleeve 203 is opened at the top of the piston chamber 2011.

[0051] The excitation component includes a telescopic sleeve 40, a plug 401, a second drive component and an opening and closing component; the inner wall of the connecting sleeve 203 is sealed with the outer wall of the guide member 20, an air guide channel 206 is provided in the guide member 20, and a second connecting pipe 2061 that can be connected to the air supply and exhaust equipment is provided at one end of the air guide channel 206, and an air guide groove 2062 connecting the air guide hole 2012 and the air guide channel 206 is provided on the outer wall of the guide member 20. The connecting sleeve 203 near the mounting block 30 and the outer wall of the guide member 20, as well as the ends of two adjacent groups of connecting sleeves 203 are all sealedly connected with the telescopic sleeve 40, and the plug 401 is horizontally and laterally sealed and slidable. It is arranged in the air guide channel 206, and a sealing block 402 is arranged on the periphery of the plug 401. The sealing block 402 is slidably arranged in the air guide groove 2062, and the side wall is sealed and fitted with the side wall of the air guide groove 2062. The second driving component is arranged on the guide member 20 and is connected to the plug 401. The second driving component is used to drive the plug 401 to slide, so that the sealing block 402 can be sealed and fitted with the ends of the multiple groups of connecting sleeves 203 away from the mounting block 30 in turn. The multiple groups of connecting sleeves 203 are all provided with opening and closing components. The plug 401 moves close to or away from the mounting block 30 to drive the opening and closing component to seal or open the air guide hole 2012 through the sealing block 402.

[0052] In the above embodiment, it can be understood that when all the grasping components are needed to grasp the biscuits, the sealing block 402 is sealed and fitted with the end of the connecting sleeve 203 away from the mounting block 30. At this time, the air supply and exhaust device (not shown) is started to inflate the air guide channel 206. At this time, the air in the air guide channel 206 can enter the piston cavity 2011 through the air guide groove 2062 and the air guide hole 2012. At this time, the piston 204 moves downward and drives the negative pressure suction cup 202 to move downward and contact the biscuits through the piston rod 205. After the negative pressure suction cup 202 contacts the biscuits, the negative pressure device (not shown) is started again to make the negative pressure suction cup 202 generate negative pressure to grasp the biscuits, which is convenient for grasping the biscuits.

[0053] When it is necessary to adjust the number of biscuits to be grabbed, the second driving component drives the plug 401 to slide close to the mounting block 30. The plug 401 slides close to the mounting block 30 so that the plug 401 passes through the currently matched connecting sleeve 203, and the sealing block 402 is sealed with the end of the front connecting sleeve 203 away from the mounting block 30. At this time, the air in the air guide channel 206 cannot be input into the connecting sleeve 203 behind the plug 401. Therefore, the air supply device for inflating the air guide channel 206 can only make the air enter the air guide holes 2012 of the multiple groups of connecting sleeves 203 in front of the plug 401, so that the multiple groups of negative pressure suction cups 202 in front of the plug 401 move downward and contact the biscuits, while the negative pressure suction cups 202 behind the plug 401 are away from the biscuits. That is, the number of biscuits to be grabbed can be adjusted according to demand by adjusting the position of the plug 401, thereby improving the practicality of the device.

[0054] And by setting up an opening and closing component, when the plug 401 slides past the connecting sleeve 203 close to the mounting block 30, the sealing block 402 drives the opening and closing component to seal the air hole 2012. At this time, the outside gas cannot enter the air hole 2012 in the connecting sleeve 203 behind the plug 401, thereby ensuring that the negative pressure suction cup 202 that does not grab the biscuits always remains away from the biscuits. It can be understood that when multiple groups of grabbing components are spaced apart, the connecting sleeve 203 in front of the plug 401 will slide over the plug 401 in turn. At this time, the sealing block 402 drives the opening and closing component to seal the air hole 2012, so that after the connecting sleeve 203 in front of the plug 401 slides over the plug 401, the gas in the piston chamber 2011 cannot escape, thereby ensuring that the negative pressure suction cup 202 that grabs the biscuits always remains in contact with the biscuits, thereby improving the stability of the device.

[0055] Specifically in the above embodiment, the second drive assembly includes a second screw 405 and a second motor 406; the second screw 405 is coaxially rotatably arranged in the air guide channel 206, and is threadedly connected to the plug 401 in a sealed manner, and the second motor 406 is arranged at one end of the guide member 20, and the output end is coaxially connected to the second screw 405. The plug 401 can be driven to slide close to the mounting block 30 by controlling the second motor 406 to drive the second screw 405 to rotate and to cooperate with the plug 401 thread, and the plug 401 can be driven to slide away from the mounting block 30 by controlling the second motor 406 to drive the second screw 405 to rotate in the opposite direction and to cooperate with the plug 401 thread, so that the position of the plug 401 can be adjusted conveniently.

[0056] See also Figure 8 and Fig. 9 In one embodiment, the opening and closing assembly includes a sealing plate 403 and a spring sheet 404; a groove 2031 connected to the air guide hole 2012 is formed on the inner wall of the connecting sleeve 203, and the sealing plate 403 is horizontally and laterally slidably arranged in the groove 2031. The sealing plate 403 can seal or open the air guide hole 2012 by sliding. A spring sheet 404 is provided on one side of the sealing plate 403, and one end of the spring sheet 404 extends out of the groove 2031 and can abut against the end of the sealing block 402.

[0057] In the above embodiment, when the plug 401 slides close to the mounting block 30, the plug 401 drives the sealing block 402 to move, and the sealing block 402 moves so that its end contacts the spring sheet 404. At this time, the sealing block 402 drives the spring sheet 404 to move, and the movement of the spring sheet 404 drives the sealing plate 403 to move so that the sealing plate 403 seals the air guide hole 2012. After the sealing plate 403 seals the air guide hole 2012, the plug 401 continues to move so that the sealing block 402 squeezes the spring sheet 404 so that The spring sheet 404 is compressed and bent back into the groove 2031. At this time, the spring sheet 404 remains stationary. When the plug 401 continues to move to cause the sealing block 402 and the spring sheet 404 to be misaligned, the extrusion force on the spring sheet 404 disappears and the spring sheet 404 is reset. When the plug 401 slides away from the mounting block 30, the sealing block 402 can drive the sealing plate 403 to move in the opposite direction through the spring sheet 404 to open the air guide hole 2012, thereby driving the sealing plate 403 to seal or open the air guide hole 2012.

[0058] Specifically in the above embodiment, the second slide groove 2032 is opened on the top and bottom surfaces of the groove 2031, and the top and bottom ends of the sealing plate 403 are provided with limit blocks 4031, and the limit blocks 4031 are horizontally and laterally slidably arranged in the second slide groove 2032.

[0059] See also Figures 1 to 3 and Fig.10 In one embodiment, the spacing adjustment mechanism includes a guide block 50, an adjustment spring 501 and a guide rod 502; a guide column 301 is provided on one side of the mounting block 30, and the guide block 50 is horizontally and laterally slidably arranged on the guide column 301, and the two ends of the adjustment spring 501 are respectively connected to the mounting block 30 and the guide block 50, and the top ends of the multiple groups of mounting rods 201 are all sleeved with the adjustment spring 501, and a fixed column 101 is provided on one side of the frame 10, and the guide rod 502 is arranged on the fixed column 101, and cooperates with the frame 10 to form an angle, and a pull groove 5021 is opened on the guide rod 502 along the length direction, and a pull shaft 503 is provided on the top of the guide block 50, and the pull shaft 503 is slidably arranged in the pull groove 5021.

[0060] In the above embodiment, the installation block 30 moves through the guide column 301 to drive the guide block 50 to move, and the guide block 50 moves through the pull shaft 503 and the pull groove 5021 to drive the guide block 50 to move away from the installation block 30. The guide block 50 moves away from the installation block 30 to stretch the adjustment spring 501, and the adjustment spring 501 is stretched to drive multiple groups of installation rods 201 to be spaced apart. Conversely, the installation block 30 moves in the opposite direction and drives the guide block 50 to move in the opposite direction through the guide column 301. The guide block 50 moves in the opposite direction and drives the guide block 50 to move close to the installation block 30 through the pull shaft 503 and the pull groove 5021. The guide block 50 moves close to the installation block 30 to contract the adjustment spring 501, and the contraction of the adjustment spring 501 can drive multiple groups of installation rods 201 to move together, so as to facilitate driving multiple groups of installation rods 201 to be spaced apart or together while the installation block 30 moves.

[0061] Specifically in the above embodiment, a T-shaped slider 504 is provided on the guide block 50 , a T-shaped slide groove 3011 is provided on the guide column 301 , and the T-shaped slider 504 is horizontally and laterally slidably disposed in the T-shaped slide groove 3011 .

[0062] See also Figures 1 to 3 and Fig.10 In one embodiment, the spacing adjustment mechanism also includes an adjustment component, which includes a mounting seat 60 and a third driving component. The mounting seat 60 is horizontally and laterally slidably arranged on the fixed column 101. The third driving component connects the mounting seat 60 and the fixed column 101. The third driving component is used to drive the mounting seat 60 to slide, and the guide rod 502 is arranged on the mounting seat 60.

[0063] In the above embodiment, the mounting seat 60 is driven to move away from the frame 10 by the third driving assembly, and the movement of the mounting seat 60 drives the guide rod 502 to move. The guide rod 502 moves through the groove 5021 and the pull shaft 503 to drive the guide block 50 to move away from the mounting block 30. The guide block 50 moves away from the mounting block 30 to stretch the adjustment spring 501. At this time, the intervals of the biscuits of the multiple groups of grabbing assemblies arranged neatly in the horizontal direction at the end of the grabbing conveyor belt can be increased. Conversely, the mounting seat 60 is driven to move close to the frame 10 by the third driving assembly, and the mounting seat 60 moves to drive the guide rod 502 to move in the opposite direction. The guide rod 502 moves in the opposite direction and drives the guide block 50 to move close to the mounting block 30 through the groove 5021 and the pull shaft 503. The guide block 50 moves close to the mounting block 30 to contract the adjustment spring 501. At this time, the intervals of the biscuits of the multiple groups of grabbing assemblies arranged neatly in the horizontal direction at the end of the grabbing conveyor belt can be reduced, which is convenient for adjustment according to biscuits of different sizes and improves the practicality of the device.

[0064] Specifically in the above embodiment, the third driving assembly includes a third screw 601 and a third motor 602; a third slide groove 1011 is opened on the fixed column 101, and a connecting block 603 is arranged on one side of the mounting seat 60, and the connecting block 603 is arranged in the third slide groove 1011 for horizontal and transverse sliding. The third screw 601 is arranged horizontally and transversely, and is rotatably arranged in the third slide groove 1011, and is threadedly connected with the connecting block 603. The third motor 602 is arranged on the fixed column 101, and the output end is coaxially connected with the third screw 601.

[0065] By controlling the third motor 602 to drive the third screw 601 to rotate and cooperate with the connection block 603 thread, the mounting base 60 can be driven to move away from the frame 10. By controlling the third motor 602 to drive the third screw 601 to rotate in the opposite direction and cooperate with the connection block 603 thread, the mounting base 60 can be driven to move closer to the frame 10. It is convenient to drive the mounting base 60 to move away from or close to the frame 10.

[0066] See also Figures 1 to 3 and Fig.10 In one embodiment, the spacing adjustment mechanism also includes a rotating assembly, which includes a fixed shaft 70 and a fourth driving assembly. The fixed shaft 70 is vertically and rotatably arranged on the mounting seat 60. The guide rod 502 is arranged at the bottom end of the fixed shaft 70, and the dial shaft 503 is coaxial with the fixed shaft 70. The fourth driving assembly connects the fixed shaft 70 and the mounting seat 60, and the fourth driving assembly is used to drive the fixed shaft 70 to rotate.

[0067] When the guide rod 502 is rotated, the guide rod 502 is driven to rotate by the fourth driving assembly. When the guide rod 502 is rotated to increase the angle formed by the guide rod 502 and the frame 10, the mounting block 30 moves through the lever shaft 503 and the lever groove 5021 to drive the guide block 50 to move away from the mounting block 30 to increase the stroke. Therefore, the longer the stretch of the adjustment spring 501 is, the larger the interval between the multiple groups of mounting rods 201 is. Conversely, when the guide rod 502 is rotated in the opposite direction to reduce the angle formed by the guide rod 502 and the frame 10, the mounting block 30 moves through the lever shaft 503 and the lever groove 5021 to drive the guide block 50 to move away from the mounting block 30 to shorten the stroke. Therefore, the stretch of the adjustment spring 501 is shortened, and the interval between the multiple groups of mounting rods 201 is smaller. This makes it easier to adjust the interval when the biscuits are placed on the lower film of the packaging bag according to needs, thereby improving the practicality of the device.

[0068] Specifically in the above embodiment, the fourth drive assembly includes a worm wheel 701, a worm 702 and a fourth motor 703; the worm wheel 701 is coaxially arranged on the fixed shaft 70, the worm 702 is rotatably arranged on the mounting seat 60 and meshed with the worm wheel 701, and the fourth motor 703 is arranged on the mounting seat 60, and the output end is coaxially connected to the worm 702.

[0069] The worm wheel 701 can be driven to rotate by controlling the fourth motor 703 to drive the worm 702 to rotate and engage with the worm wheel 701. The rotation of the worm wheel 701 drives the guide rod 502 to rotate through the fixed shaft 70. The worm wheel 701 can be driven to rotate in the reverse direction by controlling the fourth motor 703 to drive the worm 702 to rotate in the reverse direction and engage with the worm wheel 701. The reverse rotation of the worm wheel 701 drives the guide rod 502 to rotate in the reverse direction through the fixed shaft 70, which makes it convenient to drive the guide rod 502 to rotate.

[0070] The specific implementation of the above-mentioned horizontal row spacing adjustment device is as follows:

[0071] By starting the air supply and exhaust device to inflate the air in the air channel 206, at this time, the air in the air channel 206 can enter the piston chamber 2011 through the air guide groove 2062 and the air guide hole 2012. At this time, the piston 204 moves downward and drives the negative pressure suction cup 202 to move downward and contact the biscuit through the piston rod 205. When the negative pressure suction cup 202 contacts the biscuit, the negative pressure device is started again to make the negative pressure suction cup 202 generate negative pressure to grab the biscuit. After grabbing the biscuit, the first motor 303 is controlled to drive the first screw 302 to rotate. The first screw 302 rotates and cooperates with the thread of the mounting block 30 to drive the mounting block 30 to move. The mounting block 30 is 0 moves to drive the guide member 20 to move, and the movement of the guide member 20 can drive the biscuits grabbed by the negative pressure suction cup 202 to move toward the lower film of the packaging bag. At the same time, the installation block 30 moves through the guide column 301 to drive the guide block 50 to move, and the movement of the guide block 50 drives the guide block 50 to move away from the installation block 30 through the pull shaft 503 and the pull groove 5021. The movement of the guide block 50 away from the installation block 30 can stretch the adjustment spring 501, and the stretching of the adjustment spring 501 can drive the multiple groups of installation rods 201 to be separated at intervals, so as to facilitate the synchronous separation of the biscuits in the process of placing the biscuits on the lower film of the packaging bag, thereby improving the biscuit production efficiency.
