Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco packaging equipment technology, and specifically to a box-retrieving clamp. Background Technology
[0002] In the tobacco processing and unpacking process, tobacco is generally packaged and transported to the factory for further processing. The packaged tobacco needs to be manually opened; the cartons typically consist of inner and outer cardboard boxes. The tobacco can be removed from the cartons by separating the inner and outer boxes.
[0003] Existing technology involves mounting grippers on a robotic arm to grasp the outer cardboard box of a carton, separating it from the inner cardboard box for easier removal of tobacco. The grippers hold the outer cardboard box on both sides, increasing friction through clamping force to separate the outer and inner boxes. However, because cardboard is relatively soft, it easily deforms when gripped, reducing friction and making separation inefficient. Utility Model Content
[0004] This application provides a box-removing clamp designed to increase the clamp's force on the carton, thereby improving the efficiency of separating the inner and outer cartons.
[0005] In one embodiment, a box retrieval clamp is provided, comprising:
[0006] The frame has two spaced slide rails; the extension directions of the two slide rails coincide with each other; a telescopic cylinder is fixedly installed on the frame; the extension direction of the telescopic cylinder is perpendicular to the extension direction of the slide rails.
[0007] The clamping component includes: a first clamping plate, a second clamping plate, a first drive cylinder, a second drive cylinder, and a pin assembly;
[0008] The first clamping plate and the second clamping plate are respectively connected to the two slide rails in a one-to-one sliding limit connection; the first clamping plate and the second clamping plate can move towards each other or away from each other;
[0009] Both the first drive cylinder and the second drive cylinder are fixedly connected to the frame, and the telescopic ends of the first drive cylinder and the second drive cylinder are respectively fixedly connected to the first clamping plate and the second clamping plate.
[0010] The pin assembly is fixedly connected to the first clamping plate and / or the second clamping plate; the pin assembly has a retractable needle tip, and the retraction direction of the needle tip intersects the clamping surface of the first clamping plate and / or the second clamping plate at a predetermined angle.
[0011] The second clamping plate is also fixedly connected to a pin assembly, with the extension and retraction direction of the pin intersecting the clamping surface of the second clamping plate at a predetermined angle. A flange is fixedly connected to the frame for fixed connection with the robotic arm.
[0012] The predetermined angle is 80 to 100 degrees.
[0013] In one embodiment, the frame includes a base plate with a conveyor rail and a connecting plate fixedly connected to the base plate; both the first drive cylinder and the second drive cylinder are fixedly connected to the connecting plate.
[0014] In one embodiment, the number of clamping members and the number of substrates are two in a one-to-one correspondence, the two substrates are fixedly connected to the connecting plate at intervals, and the two clamping members are connected to the two substrates in a one-to-one correspondence.
[0015] In one embodiment, a paperboard picking assembly is fixedly connected to the second clamp; the paperboard picking assembly is connected to an air tube.
[0016] In one embodiment, the paperboard picking assembly includes a telescopic cylinder and an insertion cylinder with an extendable needle; the telescopic cylinder is fixedly connected to the second clamping plate; the insertion cylinder is mounted on the telescopic head of the telescopic cylinder and is used to communicate with the air pipe.
[0017] Specifically, a solenoid valve is installed on the air tube. After the insertion cylinder is connected to the air tube, a high-pressure or negative-pressure air source is introduced into the air tube to realize the extension or contraction movement of the piston of the insertion cylinder, which in turn drives the extension and retraction movement of the needle fixedly connected to the piston.
[0018] There are two insertion cylinders. The extension and retraction directions of the two insertion cylinders intersect at 30 to 45 degrees, and the movement directions of the two needles corresponding to the two insertion cylinders also intersect at 30 to 45 degrees.
[0019] In one embodiment, the needle assembly includes a third drive cylinder fixedly connected to the first clamp and / or the second clamp, the telescopic portion of the third drive cylinder being fixedly connected to the needle tip.
[0020] In one embodiment, the extension distance of the third drive cylinder is 3.3 mm to 3.7 mm.
[0021] In one embodiment, a control component is also included, comprising a processor and a pressure sensor; the processor is fixedly connected to the substrate; the pressure sensor is mounted on both the first clamping plate and the second clamping plate; the pressure sensor, the first drive cylinder, the second drive cylinder, the telescopic cylinder, and the third drive cylinder are all electrically connected to the processor.
[0022] Specifically, the solenoid valve is also electrically connected to the processor.
[0023] In one embodiment, anti-slip strips are fixedly connected to the clamping surfaces of both the first and second clamping plates.
[0024] Specifically, the number of anti-slip strips on the clamping surfaces of each of the first and second clamping plates is two, spaced apart from each other.
[0025] The beneficial effects of this application are:
[0026] The first and second drive cylinders drive the first and second clamping plates to move towards or away from each other, enabling the loading and unloading of cartons. When the first and second clamping plates move towards each other to clamp the outer carton, the needles of the pin assembly insert into the outer carton. As the first and second clamping plates move, the insertion of the needles causes the outer carton to be pushed by the needles, separating it from the inner carton. Compared to the method where the outer carton is separated from the inner carton by friction from the first and second clamping plates, the pin assembly increases the force exerted by the first and second clamping plates on the outer carton, facilitating the separation of the inner and outer cartons and improving the carton separation efficiency. This also improves the efficiency of picking up cartons.
[0027] After the clamping component grips the carton, the telescopic cylinder's telescopic head extends and abuts against the outer carton, reducing the likelihood of the top of the outer carton tilting up due to the clamping action, thus ensuring the clamping component firmly holds the outer carton.

[0042] This application proposes improvements and innovations, and presents the following embodiments.
[0043] In some implementations, please refer to Figures 1 to 5 A box retrieval clamp is provided, comprising:
[0044] The frame 1 has two spaced slide rails 11; the extension directions of the two slide rails 11 coincide with each other; a telescopic cylinder 14 is fixedly installed on the frame 1; the extension direction of the telescopic cylinder 14 is perpendicular to the extension direction of the slide rails 11.
[0045] Clamping component 2, which includes: a first clamping plate 21, a second clamping plate 22, a first driving cylinder 23, a second driving cylinder 24, and a pin assembly 25;
[0046] The first clamping plate 21 and the second clamping plate 22 are respectively connected to the two slide rails 11 for sliding and limiting; the first clamping plate 21 and the second clamping plate 22 can move towards each other or away from each other;
[0047] The first drive cylinder 23 and the second drive cylinder 24 are both fixedly connected to the frame 1, and the telescopic ends of the first drive cylinder 23 and the second drive cylinder 24 are respectively fixedly connected to the first clamping plate 21 and the second clamping plate 22.
[0048] The pin assembly 25 is fixedly connected to the first clamping plate 21 and / or the second clamping plate 22; the pin assembly 25 has a retractable needle 251, and the retraction direction of the needle 251 intersects the clamping surface of the first clamping plate 21 and / or the second clamping plate 22 at a predetermined angle.
[0049] The second clamping plate 22 is also fixedly connected to a pin assembly 25, and the extension and retraction direction of the pin 251 intersects the clamping surface of the second clamping plate 22 at a predetermined angle. A flange is fixedly connected to the frame 1 for fixed connection with the robotic arm. The predetermined angle is 80 to 100 degrees.
[0050] The first drive cylinder 23 and the second drive cylinder 24 drive the first clamping plate 21 and the second clamping plate 22 to move towards or away from each other, thereby enabling the picking and placing of cartons. When the first clamping plate 21 and the second clamping plate 22 move towards each other to clamp the outer carton 5, the needle 251 of the pin assembly 25 inserts into the outer carton 5. When the first clamping plate 21 and the second clamping plate 22 move, the outer carton 5 is pushed by the needle 251 as it is inserted into the inner carton 6, causing the outer carton 5 to separate from the inner carton 6. Compared to the case where the outer carton 5 is separated from the inner carton 6 by the friction of the first clamping plate 21 and the second clamping plate 22, the needle 251 assembly increases the force exerted by the first clamping plate 21 and the second clamping plate 22 on the outer carton 5, facilitating the separation of the inner and outer cartons and improving the carton separation efficiency. This also improves the efficiency of picking up cartons. After the clamping member 2 clamps the carton, the telescopic cylinder 14 extends and abuts against the outer carton 5, reducing the possibility of the top of the outer carton 5 tilting up due to the clamping action of the clamping member 2, thus ensuring the firmness of the clamping member 2 in clamping the outer carton 5.
[0051] In some embodiments, the frame 1 includes a base plate 12 having a conveying slide rail 11 and a connecting plate 13 fixedly connected to the base plate 12; the first drive cylinder 23 and the second drive cylinder 24 are both fixedly connected to the connecting plate 13. The base plate 12 facilitates the installation of the slide rail 11, and the connecting plate 13 provides a position for the installation of the first drive cylinder 23 and the second drive cylinder 24.
[0052] In some embodiments, the number of clamping members 2 and substrates 12 is two in a one-to-one correspondence. The two substrates 12 are fixedly connected to the connecting plate 13 at intervals, and the two clamping members 2 are connected to the two substrates 12 in a one-to-one correspondence. The two clamping members 2 can increase the force on the outer cardboard box 5, so as to better separate the outer cardboard box 5 and the inner cardboard box 6.
[0053] In some embodiments, the paperboard taking assembly 3 includes a telescopic cylinder 31 and an insertion cylinder 32 with an extendable needle; the telescopic cylinder 31 is fixedly connected to the second clamping plate 22; the insertion cylinder 32 is mounted on the telescopic head of the telescopic cylinder 31 and is used to communicate with an air pipe. The structure of moving the insertion cylinder 32 by driving the telescopic cylinder 31 is simple and reasonably designed.
[0054] Specifically, a solenoid valve is installed on the trachea. The solenoid valve is used to better control the extension and retraction of the needle tip.
[0055] After the insertion cylinder 32 is connected to the air pipe, a high-pressure or negative-pressure air source is introduced into the air pipe to realize the extension or contraction movement of the piston of the insertion cylinder 32, which in turn drives the extension and retraction movement of the pointed needle 33 fixedly connected to the piston.
[0056] There are two insertion cylinders 32, and the extension and retraction directions of the two insertion cylinders 32 intersect at an angle of 30 to 45 degrees. The movement directions of the two needles 33 corresponding to the two insertion cylinders 32 also intersect at an angle of 30 to 45 degrees. The needles 33 intersecting at an angle of 30 to 45 degrees can be better inserted into the cardboard 7 and prevent the cardboard 7 from slipping out of the needles 33.
[0057] The cardboard 7 is packed inside the carton, including paper used to record information about the cigarette packs in the carton.
[0058] In some embodiments, the needle assembly 25 includes a third drive cylinder 252 fixedly connected to the first clamping plate 21 and / or the second clamping plate 22, and the telescopic portion of the third drive cylinder 252 is fixedly connected to the needle tip 251. The third drive cylinder 252 drives the telescopic movement of the needle tip 251, resulting in a simple and rationally designed structure.
[0059] In some embodiments, the telescopic distance of the third drive cylinder 252 is 3.3 mm to 3.7 mm. A telescopic distance of 3.3 mm to 3.7 mm allows it to penetrate the outer cardboard box 5 without touching the inner cardboard box 6, thus enabling better separation of the inner and outer cardboard boxes 5.
[0060] In some embodiments, a control component 4 is further included, comprising a processor 41 and a pressure sensor 42. The processor 41 is fixedly connected to the base plate 12. Pressure sensors 42 are mounted on both the first clamping plate 21 and the second clamping plate 22. The pressure sensor 42, the first drive cylinder 23, the second drive cylinder 24, the telescopic cylinder 31, and the third drive cylinder 252 are all electrically connected to the processor 41. The processor 41 can more intelligently control the actions of the pressure sensor 42, the first drive cylinder 23, the second drive cylinder 24, the telescopic cylinder 31, and the third drive cylinder 252, thereby improving the intelligence of the clamp.
[0061] Specifically, the solenoid valve is also electrically connected to the processor 41.
[0062] In some embodiments, anti-slip strips 26 are fixedly connected to the clamping surfaces of the first clamping plate 21 and the second clamping plate 22. The anti-slip strips 26 can increase the friction on the outer cardboard box 5, so as to better separate the outer cardboard box 5 and the inner cardboard box 6.
[0063] Specifically, each of the first clamping plates 21 and the second clamping plates 22 has two anti-slip strips 26 spaced apart from each other on its clamping surface. The two anti-slip strips 26 can increase the friction against the outer cardboard box 5.
[0064] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
