Description

Technical Field

[0001] This invention relates to the field of heat insulation pad processing technology, specifically to a heat insulation pad counting and packaging equipment. Background Technology

[0002] After each heat insulation pad is manufactured and passes inspection, it needs to be counted and the pre-ordered number of stacked pads bundled and packaged. Before packaging, foam needs to be placed on the sides of the heat insulation pads. Then, an automatic tape wrapping machine is used to wrap paper tape and package the heat insulation pads and foam together. Currently, there is no processing equipment on the market that can count the heat insulation pads and package them together with the foam. Furthermore, existing heat insulation pad packaging equipment still requires manual assistance in loading the foam, and its production capacity is limited.

[0003] To address the aforementioned technical problems, this invention provides a heat insulation pad counting and packaging device. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a thermal insulation pad counting and packaging equipment that can realize the quantitative counting of thermal insulation pads, automatic foam filling and packaging, thereby improving production efficiency and reducing the required manpower.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a heat insulation pad counting and packaging device, including a quantitative discharging device and a packaging device. The quantitative discharging device counts and quantifies the heat insulation pads and then sends them to the packaging device. The packaging device includes a conveying mechanism, a foam loading mechanism, a first belt-pressing mechanism, and a foam hopper. The conveying mechanism drives the heat insulation pads to pass through the foam loading station and the first belt-pressing station in sequence. The foam loading mechanism is set at the foam loading station and loads the foam onto the heat insulation pad located at the foam loading station. The first belt-pressing mechanism is set at the first belt-pressing station and packages the heat insulation pad and foam together at the first belt-pressing station. A foam sorting mechanism is set on the foam hopper. The foam sorting mechanism sorts the foam in the foam hopper and sends it to the foam gripping position of the foam loading mechanism. The quantitative discharge device sends the counted heat insulation pads to the packaging device. Then, the conveyor mechanism drives the counted heat insulation pads through the foam loading station and the first belt-bearing station in sequence. The foam loading mechanism loads the sorted foam from the foam hopper onto the heat insulation pads. The first belt-bearing mechanism then packages the heat insulation pads and foam together.

[0006] As an optional solution, the foam sorting mechanism includes a directional discharge component and a sorting conveyor component. The directional discharge component is located inside the foam hopper, orienting and conveying the foam from the hopper to the sorting conveyor component. The sorting conveyor component has an outlet channel along the conveying direction on its conveying surface. A positioning guide component is located at the entrance end of the outlet channel on the conveying surface of the sorting conveyor component. The positioning guide component corrects the position and orientation of the foam on the sorting conveyor component and guides the foam into the outlet channel. An output area is located at the exit end of the outlet channel on the conveying surface of the sorting conveyor component, and the foam gripping position of the foam loading mechanism is located in the output area. The directional discharge component conveys foam with a specific orientation from the foam hopper to the sorting conveyor component, which then conveys the foam to the gripping position of the foam loading mechanism for easy gripping. During the conveying process, the sorting conveyor component also uses the positioning guide component to adjust the position of the foam, facilitating precise gripping by the foam loading mechanism and improving the accuracy of foam loading onto the insulation pad.

[0007] As an optional solution, the directional discharge assembly includes a first conveyor, which is inclinedly disposed within the foam hopper. Several dividing baffles are arranged along the conveying direction on the conveying surface of the first conveyor, with the spacing between adjacent dividing baffles being less than the length of the foam. A foam conveying zone is formed between adjacent dividing baffles on the first conveyor. Because the first conveyor is inclined within the foam hopper, and its conveying surface has several foam conveying zones, only foam with the appropriate orientation can enter the foam conveying zone and be conveyed out, thereby achieving preliminary sorting of the foam.

[0008] As an optional solution, the directional discharge assembly also includes a second conveyor, which is located at the end of the conveying of the first conveyor and transfers the foam conveyed by the first conveyor to the sorting conveyor assembly; the second conveyor plays a transfer role, transferring the foam directionally conveyed by the first conveyor to the sorting conveyor assembly. And / or, the directional feeding assembly also includes a third conveyor, which is disposed inside the foam hopper, and the first conveyor is disposed at the conveying end of the third conveyor. When replenishing the foam hopper, no adjustment of the foam is required; the third conveyor, in conjunction with the first conveyor, enables automatic foam feeding.

[0009] As an optional solution: the alignment guide component includes an alignment ramp, which is set at the entrance end of the outlet channel. The alignment ramp adjusts the orientation and position of the foam and guides the foam into the outlet channel. During the movement of the foam driven by the sorting and conveying component, the foam adjusts its position and orientation along the inclined surface of the alignment ramp, and the foam moves to a designated position suitable for the foam loading mechanism to grasp at the outlet channel on the sorting and conveying component.

[0010] As an optional solution, the sorting and conveying assembly is installed inside the foam hopper or at the hopper opening. The assembly is equipped with a guide plate that forms an outlet channel at its edge, causing incorrectly oriented foam to fall into the foam hopper. With the outlet channel at its edge, incorrectly oriented foam, as it passes through the outlet channel, falls back into the foam hopper because its center of gravity is outside the assembly.

[0011] As an optional solution, the foam loading mechanism includes a foam loading drive and a foam gripping fixture. The actuating part of the foam loading drive is connected to the foam gripping fixture. The foam loading drive drives the foam gripping fixture to reciprocate between the foam gripping position and the foam installation position, and loads the foam onto the heat insulation pad located at the foam loading position.

[0012] As an optional solution, the packaging device also includes a second strapping mechanism and a reversing mechanism. The reversing mechanism is located at the front end of the conveyor mechanism and reverses the orientation of the heat insulation pad packaged by the second strapping mechanism, transferring it onto the conveyor mechanism. When the heat insulation pad is packaged at the packaging device, it is first packaged by the second strapping mechanism, then reversed by the reversing mechanism to a suitable orientation for foam filling, then the foam filling mechanism fills the designated position of the heat insulation pad with foam, and finally the first strapping mechanism packages it again.

[0013] As an optional solution, the quantitative dispensing device includes a verification mechanism and at least one quantitative mechanism. The quantitative mechanism includes a measuring component and a residual material removal component. The residual material removal component removes the residual material from the measuring component based on the measurement result. The measuring component and the verification mechanism are conveying devices with weighing functions. Each measuring component is connected sequentially and then connected to the verification mechanism, which in turn connects to the conveying mechanism. The quantitative mechanism weighs and measures the insulation pads and removes any excess insulation pads. Multiple quantitative mechanisms work together to quantitatively count the insulation pads. Subsequent packaging operations can only proceed after the verification mechanism confirms the accuracy of the count.

[0014] As an optional solution, a feeding device is also included. The feeding device includes a product hopper and a feeding mechanism. A first clearance opening and a second clearance opening are respectively provided on two opposite end faces of the product hopper. A quantitative discharging device is located on one side of the second clearance opening of the product hopper. The first clearance opening and the second clearance opening are correspondingly connected and form a pushing channel within the product hopper. A stacking support is provided in the pushing channel within the product hopper, and a clearance gap is provided on the stacking support. The feeding mechanism includes a horizontal drive component, a vertical drive component, and a lifting support. The horizontal drive unit is connected to the vertical drive unit, and the vertical drive unit is connected to the lifting pallet. Driven by the horizontal and vertical drive units, the lifting pallet cyclically moves between the pushing standby position, the pushing and supporting position, and the supporting and unloading position. When the lifting pallet moves from the pushing standby position to the pushing and supporting position, the product located above the stacking support is pushed towards the quantitative discharging device. When the lifting pallet moves from the pushing and supporting position to the supporting and unloading position, the product stacked on the lifting pallet is placed onto the stacking support. The feeding mechanism transfers the heat insulation pads stacked in the product hopper to the quantitative discharging device in a stacked manner, achieving automatic feeding, reducing the labor intensity of personnel, and facilitating the counting and packaging operation of the heat insulation pads.

[0015] As an optional solution, a material stop is provided on the product hopper at the second clearance opening. The material stop is connected to the product hopper and can be raised and lowered relative to the product hopper. The part of the second clearance opening below the material stop and the first clearance opening form a pushing channel in the product hopper.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The counting and packaging equipment of this patent can automatically dispense a quantitative amount of heat insulation pads, automatically fill the heat insulation pads with foam, and automatically package the heat insulation pads. The counting accuracy and foam filling accuracy are high, avoiding the situation of missing or overfilling the heat insulation pads. The appearance of the packaged heat insulation pads is consistent. Only one person is needed to complete the operation, which effectively improves the packaging efficiency of heat insulation pads and saves labor costs. 2. Using the counting and packaging equipment of this patent, personnel only need to replenish the product hopper and foam hopper, without any other operations, effectively reducing the labor intensity of personnel; 3. The quantity of heat insulation pads is first packaged by the second belt conveyor mechanism, and then the reversing mechanism flips and reverses them to the orientation suitable for foam filling. The foam filling mechanism accurately fills the foam sorted by the foam sorting mechanism onto the heat insulation pad. Finally, the first belt conveyor mechanism packages the heat insulation pad and foam together. The directional discharge component of the foam sorting mechanism outputs the foam in the foam hopper to the sorting and conveying component. The sorting and conveying component then corrects the position of the conveyed foam so that the foam can be conveyed to the position suitable for being grasped by the foam filling mechanism. This ensures that the foam filling mechanism can accurately grasp the foam in a specific orientation and accurately fill the foam onto the heat insulation pad, ensuring that the heat insulation pad has a consistent appearance after packaging. 4. The quantitative discharge device determines the number of heat insulation pads by weighing. Based on the weighing results, excess heat insulation pads are removed. This process is repeated multiple times to determine the number of heat insulation pads, thus avoiding the omission or overfilling of heat insulation pads. 5. The feeding device provides stacked heat insulation pads to the quantitative discharging device. Personnel only need to add the heat insulation pads to the product hopper, and the feeding device can automatically feed the product, which effectively reduces the difficulty and complexity of personnel operation and helps to improve production efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] A thermal insulation pad counting and packaging device for quantitative packaging of thermal insulation pads or other sheet products.

[0021] like Figure 1 As shown, a heat insulation pad counting and packaging equipment includes a quantitative discharging device 2 and a packaging device 3. The quantitative discharging device 2 counts the stacked products and removes excess products to quantify the stacked products to a specified quantity suitable for packaging, and then transports the quantified products to the packaging device 3 for packaging. The packaging device 3 includes a conveying mechanism 31, a foam loading mechanism 32, a first belt-binding mechanism 33, and a foam hopper 34. The conveying mechanism 31 carries the quantified products sequentially through a foam loading station and a second packaging station. When the products are at the foam loading station, the foam loading mechanism 32 at the foam loading station loads the foam from the foam hopper 34 onto the heat insulation pad. When the products are at the second packaging station, the first belt-binding mechanism 33 packages the products and foam together.

[0022] In a further embodiment, the packaging device 3 also includes a second strapping mechanism 36 and a reversing mechanism 37. The second strapping mechanism 36 is located at the discharge end of the quantitative discharge device 2, which delivers a quantitative quantity of product to the second strapping mechanism 36 for packaging. The reversing mechanism 37 is located at the front end of the conveying mechanism 31, which flips and reverses the packaged product, positioning it in an orientation suitable for adding foam and repackaging. Then, the reversing mechanism 37 delivers the product to the conveying mechanism 31, which sequentially delivers the packaged product to the foam-filling station and the second packaging station for corresponding operations. The strapping directions of the first strapping mechanism 33 and the second strapping mechanism 36 are perpendicular to each other, enabling cross-packing of insulation pads and meeting the packaging requirements for sheet-like products such as insulation pads.

[0023] For details, please refer to Figure 1 , Figure 5 and Figure 6The second tape-making mechanism 36 and the first tape-making mechanism 33 adopt existing tape-making machines, and their structures will not be described in detail in this patent. The reversing mechanism 37 includes a reversing platform, a reversing drive, a first transfer mechanism, and a second transfer mechanism. The reversing platform is located at the front end of the conveying mechanism 31. The reversing platform includes a receiving platform and a discharging platform. The receiving platform and the discharging platform are connected and their surfaces are perpendicular to each other. The reversing drive is a motor or other type of rotary drive component. The rotating part of the reversing drive is connected to the reversing platform, and the reversing drive drives the reversing platform to reciprocate between the receiving position and the discharging position. When the reversing platform is in the receiving position, it rotates to a state where the receiving platform is horizontal and the discharging platform is vertical. The receiving platform is connected to the packaging platform of the second strapping mechanism 36. The packaged products of the second strapping mechanism 36 can fall onto the discharging platform. When the reversing platform is in the discharging position, it rotates to a state where the discharging platform is horizontal and the receiving platform is vertical. The discharging platform is connected to the packaging platform of the conveying mechanism 31. During the rotation of the reversing platform, the products that were originally on the receiving platform fall onto the discharging platform.

[0024] The first transfer mechanism is located at the discharge end of the second belt-pressing mechanism 36. When the reversing platform is in the receiving position, the first transfer mechanism transfers the packaged products on the second belt-pressing mechanism 36 to the receiving platform of the reversing platform. The second transfer mechanism is located at the front end of the conveying mechanism 31, and when the reversing platform is in the discharge position, the second transfer mechanism transfers the products on the discharge platform to the conveying mechanism 31. Both the first and second transfer mechanisms are product transfer components, including a transfer drive, a lifting and adjusting component, and a transfer fixture. The transfer drive is a linear module or similar component. The moving part of the transfer drive is connected to the lifting and adjusting component, which is a vertically arranged cylinder, electric push rod, or other telescopic component. The telescopic part of the lifting and adjusting component is connected to the transfer fixture, which is a gripper, lever, or other component. The lifting and adjusting component vertically adjusts the height of the transfer fixture. After the transfer fixture is engaged with the product, the moving drive drives the transfer fixture and the product to move, thereby realizing the transfer of the product.

[0025] In some embodiments, a guide hole is provided on the discharge platform, the length direction of which is perpendicular to the surface of the receiving platform. An auxiliary plate is provided on the discharge platform, and the auxiliary plate is installed on the discharge platform by connecting components such as bolts passing through the guide hole. The auxiliary plate can move along the guide hole to adjust its position. The surface of the auxiliary plate is parallel to the surface of the receiving platform, and the auxiliary plate and the receiving platform form a clamping structure. The space on the discharge platform between the auxiliary plate and the receiving platform is the clamping area. According to the stacking height of the products to be packaged, the position of the auxiliary plate can be adjusted along the guide hole to make the specifications of the clamping area match the total height of the products. When the reversing platform is in the receiving position, the first transfer mechanism transfers the products on the second conveying mechanism 36 to the clamping area. When the reversing platform is in the discharge position, the second transfer mechanism transfers the products in the clamping area to the conveying mechanism 31. During the reversing process, the products are in the clamping area to avoid loosening of the packaged products due to reversal and overturning.

[0026] The conveying mechanism 31 is a belt conveyor or other type of conveying equipment, which drives the product to move. A guiding mechanism can be installed on the conveying surface of the conveying mechanism 31. The guiding mechanism includes two guide plates arranged along the conveying direction, forming a guiding channel between the two guide plates. The conveying mechanism 31 drives the product to move along the guiding channel. The guiding mechanism can, on the one hand, restrict the conveying direction of the product to prevent deviation, and on the other hand, prevent the product from scattering due to loosening of the packing strap. The first packing mechanism 33 is located at the end of the conveying mechanism 31. The conveying mechanism 31 directly delivers the foam-filled product to the first packing mechanism 33, which then packs the product and foam together.

[0027] Please see Figure 1 , Figure 5 and Figure 6 The foam loading mechanism 32 is located on the side of the conveying mechanism 31. The foam loading mechanism 32 includes a foam loading drive and a foam gripping fixture. The foam loading drive is a moving part in the form of a linear module or the like. The actuating part of the foam loading drive is connected to the foam gripping fixture. The foam gripping fixture is a fixture suitable for gripping block-shaped foam, such as a finger cylinder or a suction cup. The foam loading drive drives the foam gripping fixture to move back and forth between the foam gripping position and the foam installation position. When the foam gripping fixture is in the foam gripping position, it grips the foam. When it is in the foam installation position, it places the gripped foam onto the product located at the foam loading position on the conveying mechanism 31. Then, the conveying mechanism 31 drives the product containing foam to the first belt-packing position. The first belt-packing mechanism 33 packages the product and the foam together.

[0028] Please see Figure 1 and Figure 7The foam hopper 34 is used to store foam. A foam sorting mechanism 35 is provided on the foam hopper 34. The foam sorting mechanism 35 sorts the foam in the foam hopper 34 and provides it to the foam loading mechanism 32 in a specified orientation. The foam sorting mechanism 35 includes a directional discharge component 351 and a sorting conveyor component 352. The directional discharge component 351 is located in the foam hopper 34 and conveys the foam in the foam hopper 34 to the sorting conveyor component 352. The directional discharge component 351 orients and screens the foam during conveying so that the foam delivered to the sorting conveyor component 352 has a consistent orientation. The sorting conveyor component 352 conveys the foam with a specific orientation to the foam gripping position so that the foam loading mechanism 32 can directly load the foam onto the product without adjusting the foam orientation.

[0029] Specifically, the directional discharge assembly 351 includes a first conveyor 3511, which is a belt conveyor or other type of conveyor. A plurality of dividing blocks are arranged on the conveying surface of the first conveyor 3511. The dividing blocks are evenly spaced along the conveying direction of the first conveyor 3511, and the distance between adjacent dividing blocks is greater than the width of the foam but less than the length of the foam. A foam conveying area is formed on the first conveyor 3511 between adjacent dividing blocks. The dividing blocks are preferably rod-shaped or plate-shaped structures perpendicular to the conveying direction of the first conveyor 3511. The first conveyor 3511 is inclinedly disposed inside the foam hopper 34. The conveying head of the first conveyor 3511 is located at the bottom of the foam hopper 34. The foam disposed along the first conveyor 3511 in the foam hopper 34 cannot enter the foam sorting area. Only foam with a certain angular deviation from the conveying direction of the first conveyor 3511 can enter the foam conveying area and be carried out of the foam hopper by the first conveyor 3511. During the process of the inclined first conveyor 3511 carrying the foam out of the foam hopper 34, the foam gradually sticks to the separating baffle. Finally, the foam is carried out of the foam hopper 34 by the first conveyor 3511 in an orientation perpendicular to the conveying direction of the first conveyor 3511, and the foam is conveyed to the sorting conveyor assembly 352 in this specific orientation.

[0030] In a further embodiment, to reduce the space occupied by the directional discharge assembly 351, the directional discharge assembly 351 further includes a second conveyor 3512. The second conveyor 3512 is disposed at the conveying end of the first conveyor 3511, and the second conveyor 3512 transfers the foam conveyed by the first conveyor 3511 to the sorting conveyor assembly 352. The second conveyor 3512 plays a transfer role, and the conveying direction of the second conveyor 3512 can be parallel, perpendicular, or have a specific angle with the conveying direction of the first conveyor 3511. The second conveyor 3512 cooperates with the first conveyor 3511 to deliver the foam in the hopper 34 to the sorting conveyor assembly 352 in a specific orientation.

[0031] In some embodiments, the directional discharge assembly 351 further includes a third conveyor 3513, which is a belt conveyor or other form of conveying equipment. The third conveyor 3513 is disposed within the foam hopper 34, and the conveying head of the first conveyor 3511 is located at the conveying end of the third conveyor 3513. The third conveyor 3513 continuously conveys the foam in the foam hopper 34 to the first conveyor 3511. In actual production, the foam can be poured into the foam hopper 34 in an unordered manner. The third conveyor 3513 continuously feeds the foam to the first conveyor 3511, which conveys the foam along the length direction of the foam conveying area or with a small deviation from the length direction of the foam conveying area. Operators do not need to sort or arrange the foam in the foam hopper, reducing the labor intensity of personnel.

[0032] The sorting and conveying assembly 352 has a guide plate arranged along the conveying direction on its conveying surface. An outlet channel along the conveying direction is formed on one side of the outlet end face of the guide plate on the sorting and conveying assembly 352. A positioning guide component 353 is arranged on the conveying surface of the sorting and conveying assembly 352 at the entrance end of the outlet channel. During the process of conveying foam by the sorting and conveying assembly 352, the positioning guide component 353 adjusts the orientation and position of the foam so that the foam enters the outlet channel in the direction of the length of the outlet channel. An output area is arranged on the conveying surface of the sorting and conveying assembly 352 at the outlet end of the outlet channel. The sorting and conveying assembly 352 drives each foam through the outlet channel and moves it to the output area. The foam grabbing position of the foam loading mechanism 32 is arranged in the output area. The foam loading mechanism 32 can grab the oriented foam in the output area and load it onto the product. The purpose of setting an export channel and a positioning and import component on the sorting and conveying assembly 352 is to concentrate and transport the foam to a designated position, so that the foam loading mechanism 32 can pick it up from the designated position, thus avoiding the foam from being scattered and causing the foam loading mechanism 32 to need to adjust the picking position according to the position of the foam.

[0033] In some embodiments, a pushing mechanism is provided at the output area. The pushing mechanism is a telescopic component. The pushing mechanism pushes the foam conveyed by the sorting and conveying component 352 to the outside of the conveying surface of the sorting and conveying component 352. The foam loading mechanism 32 can grab the foam pushed out by the pushing mechanism and load it onto the product.

[0034] The alignment guide component 353 includes an alignment ramp, which is disposed on the conveying surface of the sorting and conveying component 352 and has a pre-reserved gap with the conveying surface. The alignment ramp is located at the entrance end of the outlet channel and is inclined relative to the length direction of the outlet channel. During the process of the sorting and conveying component 352 driving the foam to be conveyed, the foam comes into contact with the alignment ramp, and the orientation and position of the foam are adjusted by the alignment ramp. Finally, the foam moves into the outlet channel along the direction of the outlet channel.

[0035] In some embodiments, the alignment ramp and the guide plate are an integral structure, with the portion of the guide plate near the inlet end of the outlet channel bent away from the outlet channel, and the bent portion of the guide plate forming the alignment ramp. In other embodiments, the alignment component and the guide plate are separate parts.

[0036] As an optional implementation, the alignment guide component 353 includes at least two alignment ramps. During the process of the sorting and conveying component 352 driving the foam to be conveyed, the foam sequentially contacts and engages with each alignment ramp. The multiple alignment ramps sequentially contact and engage with the foam, improving the orientation and alignment effect of the foam.

[0037] In this embodiment, when the directional discharge component 351 conveys the foam to the sorting conveyor component 352, the foam is perpendicular to the conveying direction of the sorting conveyor component 352. During the conveying process of the foam by the sorting conveyor component 352, the alignment plate contacts the foam, adjusting the orientation and position of the foam. This causes the foam to move towards the entrance of the outlet channel while simultaneously flipping and adjusting its own orientation, ultimately allowing the foam to pass through the outlet channel in the direction of the sorting conveyor component 352's conveying direction. Furthermore, by rationally arranging the position of the directional discharge component 351, the foam can also be conveyed to the sorting conveyor component 352 in an orientation parallel to its conveying direction. In this case, only the position of the foam needs to be adjusted to maintain its orientation as it enters the outlet channel.

[0038] In a preferred embodiment, the sorting and conveying assembly 352 is disposed inside the foam hopper 34 or at the opening of the foam hopper 34. A guide plate is disposed at the edge of the sorting and conveying assembly 352, forming an outlet channel. When foam passes through the outlet channel, it can detach from the outlet channel at the edge of the sorting and conveying assembly 352. The width of the outlet channel is adapted to the width of the foam, allowing only a single piece of foam with the correct orientation to pass through. When foam with an incorrect orientation enters the outlet channel, due to the obstruction of the guide plate, most of the foam extends outside the sorting and conveying assembly 352, and its center of gravity is located outside the sorting and conveying assembly 352, thus allowing it to detach from the sorting and conveying assembly 352 and fall back into the foam hopper 34.

[0039] Please see Figure 1 and Figure 2The quantitative discharging device 2 includes a verification mechanism 23 and a quantitative mechanism. The quantitative mechanism includes a measuring component 21 and a surplus material removal component 22. Both the measuring component 21 and the verification mechanism 23 are conveying devices with weighing functions. They can weigh the products during the conveying process and determine the quantity of products by analyzing the weight, thereby counting the products. Of course, the measuring component 21 and the verification mechanism 23 can also be conveying devices with other counting functions. The surplus material removal component 22 includes a material picking drive and a material picking fixture. The material picking drive is a linear module driven by a motor. The material picking drive moves the material picking fixture and removes the excess products from the measuring component 21. Then, the measuring component 21 sends the products to the verification mechanism 23. The verification mechanism 23 verifies the quantity of the products. If the quantity is correct, the products are sent to the packaging device 3. If the quantity is incorrect, the products are not conveyed to the packaging device 3, and an alarm signal is issued in conjunction with the linked alarm, or the equipment on the production line is stopped.

[0040] The material handling fixture is a suction cup type fixture suitable for gripping the heat insulation pad. The material handling drive drives the material handling fixture to move, and one heat insulation pad can be removed from the measuring component 21 each time. In order to avoid material blockage on the quantitative dispensing device 2 and to achieve continuous production, the quantitative mechanism is set to two or more. Since the error of feeding material to the quantitative dispensing device 2 is generally within two pieces in daily production, the quantitative mechanism is preferably two.

[0041] The measuring components 21 of each quantitative mechanism are connected in sequence. Each measuring component 21 has a corresponding residual material removal component 22. When the product is on the first measuring component 21, the measuring component 21 transports the product and weighs it. When the measured weight of the product exceeds the predetermined weight range, the corresponding residual material removal component 22 is activated to remove a piece of the product. Then the product is transported to the next measuring component 21, which transports the product and weighs it. When the measured weight of the product still exceeds the predetermined weight range, the corresponding residual material removal component 22 is activated to remove a piece of the product. Then the product is transported to the next measuring component 21 or the verification mechanism 23. The verification mechanism 23 transports the product and weighs it. The product is sent to the packaging device 3 only when the product weight is within the predetermined weight range.

[0042] In some embodiments, the metering mechanism also includes a discharge conveying assembly, which is a belt conveyor or other form of conveying component. The discharge conveying assembly can also be replaced by a container for placing the product. The residual material removal assembly 22 removes the product from the measuring assembly 21 and places it onto the discharge conveying mechanism.

[0043] When counting and packaging heat insulation pads using the counting and packaging equipment of this invention, the stacked heat insulation pads are placed on the quantitative mechanism. The number of heat insulation pads in each stack should be greater than or equal to the number of packages. The quantitative mechanism counts and measures the product quantity, and the verification mechanism 23 verifies the quantity before sending the measured heat insulation pads to the packaging device 3 for packaging. Of course, the surplus material removal component 22 is used in conjunction with the discharge conveying component. If the number of heat insulation pads on the quantitative mechanism is less than the number of packages, the surplus material removal component 22 can also grab heat insulation pads from the discharge conveying component and place them on the missing heat insulation pads, so that the number of heat insulation pads in each stack should be greater than or equal to the number of packages.

[0044] Please see Figure 1 and Figure 2 In some embodiments, the heat insulation pad counting and packaging equipment further includes a feeding device 1, which includes a product hopper 11 and a feeding mechanism 12. The feeding mechanism 12 transfers the products from the product hopper 11 to a quantitative discharging device 2. A stacking channel is vertically arranged inside the product hopper 11, and the products are stacked one by one inside the product hopper 11. A second clearance opening is provided on the end face of the product hopper 11 facing the quantitative discharging device 2, and a first clearance opening is also provided on the other end face of the product hopper 11. The first clearance opening and the second clearance opening are respectively located on two opposite end faces of the product hopper 11, and their positions correspond to each other. The first clearance opening, the second clearance opening, and the area inside the product hopper 11 corresponding to the first clearance opening and the second clearance opening are connected to form a pushing channel. A stacking support member 111 is provided inside the product hopper 11 at the pushing channel. The products in the product hopper 11 are stacked on the stacking support member 111, and the stacking support member 111 is also provided with a clearance gap suitable for the lifting pallet 123 of the feeding mechanism 12 to pass through. During feeding, the lifting pallet of the feeding mechanism 12 moves along the pushing channel from the first clearance opening to the second clearance opening, and pushes multiple products in the product hopper 11 from the second clearance opening out of the product hopper 11.

[0045] The feeding mechanism 12 includes a horizontal drive component 121, a vertical drive component 122, and a lifting pallet 123. The horizontal drive component 121 is a horizontally arranged telescopic component or a linear module, and the vertical drive component 122 is a vertically arranged telescopic component or a linear module. The actuating part of the horizontal drive component 121 is connected to the vertical drive component 122, and the actuating part of the vertical drive component 122 is connected to the lifting pallet 123. The horizontal drive component 121 can drive the vertical drive component 122 and the lifting pallet 123 to move horizontally reciprocally, and the vertical drive component 122 can drive the lifting pallet 123 to move vertically reciprocally. The upper end face of the lifting pallet 123 is provided with a material-supporting end face, and the side end face of the lifting pallet 123 is provided with a material-pushing end face.

[0046] Driven by the combined action of the horizontal drive unit 121 and the vertical drive unit 122, when the lifting pallet 123 is at the first clearance opening side of the product hopper 11, the lifting pallet 123 is in the push-out standby position. At this time, the horizontal drive unit 121 drives the lifting pallet 123 to move along the push-out channel towards the second clearance opening. The push-out end face contacts the product in the product hopper 11 and gradually pushes the product located in the push-out channel out of the product hopper 11. When the lifting pallet 123 completely pushes the product out of the push-out channel from the product hopper 11, the lifting pallet 123 is in the push-out position. At this time, the lifting pallet 123 is in the push-out support position. The material support end face of 3 is inside the product hopper 11, and the products in the product hopper 11 are stacked on the material support end face; when the lifting pallet 123 is in the material support position, the vertical drive component 122 drives the lifting pallet 123 to move downward, the lifting pallet 123 passes through the clearance gap and leaves the product hopper 11, the lifting pallet 123 moves to the material unloading position, and the products in the product hopper 11 are finally stacked on the stacking support component 111 during the downward movement of the lifting pallet 123; then the vertical drive component 122 and the horizontal drive component 121 cooperate to drive the lifting pallet 123 to move back to the material push waiting position to wait for the next material push. The horizontal drive component 121 and the vertical drive component 122 work together to drive the lifting pallet 123 to move cyclically between the push-up waiting position, the push-up material support position, and the material support unloading position, thereby continuously pushing out the products in the product hopper 11. Furthermore, by reasonably setting the size of the second clearance opening and the height of the lifting pallet 123 in the push-up waiting position and the push-up material support position, the feeding mechanism 12 can push out a specified amount of products each time.

[0047] In a further embodiment, a baffle 112 is provided on the product hopper 11 at the second clearance opening. The baffle 112 is plate-shaped or block-shaped. The baffle 112 is connected to the product hopper 11 and can be raised and lowered relative to the product hopper 11. The part of the second clearance opening below the baffle 112 and the first clearance opening form a pushing channel in the product hopper 11. By adjusting the height of the baffle 112 and adaptively adjusting the height of the lifting pallet 123 at the pushing standby position and the pushing pallet position, the feeding amount of the feeding mechanism 12 can be adjusted.

[0048] The feeding device 1 sends the stacked heat insulation pads to the quantitative discharging device 2. The quantitative discharging device 2 counts and quantifies the products, and then sends them to the packaging device 3. The packaging device 3 packages the products and flips them over. Before packaging again, the foam loading mechanism 32 loads foam into the designated position of the products. Then the foam and products are packaged together, thus automatically and efficiently completing the quantitative packaging of the heat insulation pads.
