A high speed pusher case packing system

Abstract

This invention discloses a high-speed side-push type carton packing system in the field of packaging equipment technology, including: a frame and a feeding and conveying mechanism, a stacking mechanism, a storage mechanism, an opening mechanism, a packing mechanism, and a sealing mechanism mounted on the frame. The opening mechanism is used to pick up the packaging cartons stacked on the storage mechanism and unfold them so that the opening of the packaging carton faces horizontally. The packing mechanism includes a support and a push plate, a limiting baffle, and a first driving component mounted on the support. This invention abandons the traditional vertical gravity unloading method and instead adopts a side-push horizontal packing method. The first driving component precisely controls the push plate's movement, smoothly pushing the vertically stacked items from the side into the unfolded packaging carton, eliminating the impact and vibration generated during the free fall of materials, avoiding the risk of breakage of fragile items during packing, and ensuring the consistency and integrity of the product's posture before and after entering the carton.

Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and more specifically to a high-speed side-push box packing system. Background Technology

[0002] In the field of modern industrial automated packaging, especially in the food, beverage, pharmaceutical, and daily chemical industries, packing products into outer packaging cartons is a crucial final step in the production line. Currently, the most widely used carton packing equipment in the industry mainly adopts the vertical drop packing method. During the packing process, the bottom of the carton is usually sealed before entering the packing station, which divides the packaging work into two discontinuous parts: first, the bottom sealing is completed on the carton opening / sealing machine, then the filling is done on the carton packing machine, and finally the top sealing is completed on the sealing machine. However, this segmented operation not only requires additional equipment investment, but also makes it difficult to unify the production cycle. The material flow between workstations is time-consuming, which seriously restricts the high-speed operation of the entire production line. Furthermore, in the vertical packing mode, the product relies on gravity to fall, and the impact force during the fall process can easily affect the product, affecting the packing qualification rate. Summary of the Invention

[0003] The purpose of this invention is to provide a high-speed side-push packing system that solves the problems existing in the current vertical packing system.

[0004] The present invention achieves the above objectives through the following technical solution: a high-speed side-push type carton packing system, comprising: a frame and a feeding conveying mechanism, a stacking mechanism, a storage mechanism, an opening mechanism, a packing mechanism and a sealing mechanism mounted on the frame. The stacking mechanism is used to vertically stack the items conveyed by the feeding conveying mechanism, and the opening mechanism is used to pick up the packaging cartons stacked on the storage mechanism and unfold them so that the opening of the packaging cartons faces horizontally. The packing mechanism includes a support frame and a push plate, a limiting baffle, and a first driving member mounted on the support frame. The first driving member is used to drive the push plate to move so that it pushes the vertically stacked items from the side into the unfolded packaging box until the items contact the limiting baffle.

[0005] Preferably, the bracket is provided with a third driving member to drive the limiting baffle to move closer to or away from the push plate.

[0006] Preferably, the bracket is provided with a spreading component and a second driving member for driving the spreading component to move. The spreading component is located between the push plate and the limiting baffle, and the moving direction of the spreading component is the same as the moving direction of the push plate.

[0007] Preferably, the spreading assembly includes a support frame, two spreading plates slidably disposed on the support frame, and a fourth driving member for changing the distance between the two spreading plates.

[0008] Preferably, the unpacking mechanism includes a mounting frame, an adsorption element disposed on the mounting frame, a sixth driving element for driving the adsorption element to flip, a support plate disposed on the adsorption element, and a seventh driving element for driving the support plate to rotate.

[0009] Preferably, the mounting frame is provided with two sets of gate closing blade assemblies and a fifth driving component for changing the distance between the two sets of gate closing blade assemblies, and the mounting frame is provided with a cylinder for driving the gate closing blade assemblies to rise and fall.

[0010] Preferably, the storage tank mechanism includes a lifting component, a second frame disposed on the moving end of the lifting component, two transmission mechanisms disposed on the second frame, a spacing adjustment component for changing the spacing between the two transmission mechanisms, and a tank baffle disposed on one side of the second frame.

[0011] Preferably, the baffle includes a frame, a limiting plate disposed on the side wall of the frame, a baffle disposed on the frame, and an eighth driving member for driving the baffle to move.

[0012] Preferably, the palletizing mechanism includes a first frame and two side baffles, a lifting assembly and a support block disposed on the first frame; The support block is hinged to the first frame, and the cross-section of the support block is triangular.

[0013] The beneficial effects of this invention are as follows: 1. Abandoning the traditional vertical gravity unloading method, a side-push horizontal packing method is adopted instead. The first drive unit precisely controls the push plate action, which smoothly pushes the vertically stacked items into the unfolded packaging box from the side. This eliminates the impact and vibration generated during the free fall of materials, avoids the risk of damage to fragile items during packing, and prevents the shape disorder or uneven stacking of flexible packaging products due to falling and rolling. This ensures the consistency and integrity of the product's posture before and after entering the box. 2. Due to the side-push method, the bottom of the packaging box does not need to be pre-sealed before filling. The packaging box can enter the packing station with the bottom open. After the items are pushed in and accurately positioned by the limiting baffle, the bottom is folded and sealed in a unified manner. This eliminates the bottom sealing process that must be carried out separately before traditional packing, making the entire packaging process more seamless, greatly shortening the production cycle, and significantly improving the operating efficiency of the entire line.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1

[0018] Please see Figure 1 and Figure 2 A high-speed side-push type box packing system includes: a frame 1, on which a feeding conveyor 2, a palletizing mechanism 3, a box storage mechanism 4, a box opening mechanism 5, a box packing mechanism 6, and a box sealing mechanism 7 are provided; the palletizing mechanism 3 is located downstream of the feeding conveyor 2, the box opening mechanism 5 is located below the box storage mechanism 4, the box packing mechanism 6 is located below the palletizing mechanism 3 and the box opening mechanism 5, and the box sealing mechanism 7 is located downstream of the box packing mechanism 6; the feeding conveyor 2 can be a conveyor belt conveying mechanism; Please see Figure 1 , Figure 2 and Figure 7 The packing mechanism 6 includes a bracket 601, which is mounted on the frame 1. The bracket 601 is provided with a first driving member 603 (which can be an electric telescopic rod or a driving mechanism composed of a motor, transmission wheel and transmission belt). The moving end of the first driving member 603 is provided with a push plate 602. The moving direction of the push plate 602 is perpendicular to the conveying direction of the feeding conveying mechanism 2. The bracket 601 is provided with a limiting baffle 605. The limiting baffle 605 and the push plate 602 are located below the bracket 601 and are opposite to each other.

[0019] It should be noted that the packing system works as follows: Packaging boxes containing items are conveyed one by one by the feeding conveyor 2 to the palletizing mechanism 3 for palletizing, stacking several items into a row and conveying them to the feeding station (located between the pusher plate 602 and the limiting baffle 605); the opening mechanism 5 picks up a packaging carton from the storage mechanism 4 and opens the carton, aligning the inlet of the carton with the stacked items; the first driving member 603 drives the pusher plate 602 to move, pushing the vertically stacked items from the side into the unfolded packaging box until the items contact the limiting baffle 605, at which point the first driving member 603 drives the pusher plate 602 to reset; the packaging boxes containing items are then conveyed to the sealing mechanism 7 for sealing and packing.

[0020] It should also be noted that the sealing mechanism 7 uses tape to seal both sides of the packaging carton. The sealing mechanism 7 is existing equipment and will not be described in detail here.

[0021] In this embodiment, as a further optimization, please refer to... Figure 7 The bracket 601 is equipped with a third driving component 606 (such as an electric telescopic rod), and a limiting baffle 605 is provided on the moving end of the third driving component 606; the third driving component 606 drives the limiting baffle 605 to move, so that it approaches or moves away from the push plate 602; before the product is loaded into the packaging carton, the third driving component 606 drives the limiting baffle 605 to move towards the packaging carton, so that when the push plate 602 pushes the product into the packaging carton, the product will not pass through the packaging carton.

[0022] In this embodiment, as a further optimization, please refer to... Figure 7The bracket 601 is equipped with a second driving component 604 (such as an electric telescopic rod). The moving end of the second driving component 604 is equipped with a spreading component 607. The spreading component 607 is located between the push plate 602 and the limiting baffle 605. The moving direction of the spreading component 607 is the same as the moving direction of the push plate 602. Before the product is loaded into the packaging carton, the second driving component 604 drives the spreading component 607 to move and contact the packaging carton, spreading the packaging carton open. This allows the push plate 602 to smoothly push the stacked product into the packaging carton without being obstructed by the deformation of the packaging carton or the carton leaf, thereby improving packaging efficiency.

[0023] In this embodiment, as a further optimization, please refer to... Figure 7 The expansion assembly 607 includes a support frame 6071, two expansion plates 6073 slidably disposed on the bottom wall of the support frame 6071, and a fourth driving member 6072 (such as a cylinder) disposed on the support frame 6071. The moving end of the fourth driving member 6072 is connected to the expansion plate 6073. The fourth driving member 6072 drives the expansion plate 6073 to move, thereby changing the distance between the two expansion plates 6073, ensuring that the expansion assembly 607 can fully expand the packaging carton, and also adapting to the expansion needs of packaging cartons of different sizes.

[0024] Example 2

[0025] As a further optimization of Example 1, please refer to Figure 5 and Figure 6 The unpacking mechanism 5 includes a mounting frame 501, on which a sixth driving member 504 (which may be a servo motor) is mounted. A support platform is mounted on the output shaft of the sixth driving member 504. An adsorption member 502 (vacuum adsorption mechanism) is mounted on the top of the support platform. A support plate 503 is hinged to the top wall of the support platform. A seventh driving member 507 (such as a servo motor) is mounted on the support platform. The output shaft of the seventh driving member 507 is connected to the support plate 503 to drive the support plate 503 to rotate. The rotation direction of the support plate 503 is the same as the rotation direction of the support platform. The rotation direction of the support platform is on the same longitudinal plane as the transmission direction of the feeding conveying mechanism 2. The unpacking mechanism 5 picks up the packaging paper from the storage box mechanism 4. When the box is being opened, the seventh driving component 507 drives the support plate 503 to rotate towards the storage mechanism 4, so that the support plate 503 and the support platform are on the same plane. At the same time, the sixth driving component 504 drives the support platform to rotate towards the storage mechanism 4, so that the adsorption component 502 adheres to one side of the packaging carton and adsorbs it. Then, the sixth driving component 504 drives the support platform to rotate in the opposite direction, removing the packaging carton from the storage mechanism 4. During the process of moving the packaging carton, the seventh driving component 507 drives the support plate 503 to rotate in the opposite direction, so that the support plate 503 and the support platform form a vertical angle. During this process, the support plate 503 squeezes one side of the packaging carton, causing the folded packaging carton to unfold, thus opening the packaging carton.

[0026] In this embodiment, as a further optimization, please refer to... Figure 5 and Figure 6 The mounting frame 501 is equipped with a fifth drive component 506 (such as a servo slide). The moving end of the fifth drive component 506 is equipped with two box-closing leaf assemblies 505 (including a motor, a rotating rod on the output shaft of the motor, and a pressure rod on the rotating rod. The motor drives the rotating rod to rotate, so that the pressure rod applies pressure to the box leaf to push the box leaf to move). The two box-closing leaf assemblies 505 are located on both sides of the support platform. The fifth drive component 506 drives the two box-closing leaf assemblies 505 to move, so as to change the distance between the two box-closing leaf assemblies 505. The box-closing leaf assemblies 505 are used to close the box leaf of the packaging carton near the storage mechanism 4 after the product is loaded. The mounting frame 501 is equipped with a cylinder 508. The moving end of the cylinder 508 is connected to the fifth drive component 506. The cylinder 508 is used to drive the fifth drive component 506 to rise and fall, so as to change the height of the box-closing leaf assembly 505. When the box-closing leaf assembly 505 is not in use, its height is lowered to avoid affecting the opening of the carton.

[0027] In this embodiment, as a further optimization, please refer to... Figure 1 , Figure 3 and Figure 4 The storage box mechanism 4 includes two lifting components 404 (such as servo slides). Each lifting component 404 has a second frame 401 on its moving end. A spacing adjustment component 403 is provided between the two second frames 401. The spacing adjustment component 403 includes a lead screw and two sliding sleeves fitted onto the outer wall of the lead screw. The lead screw rotates between the two second frames 401. A transmission mechanism 402 (belt transmission mechanism) is installed on each of the two sliding sleeves. A box stop 405 is provided on the side of the second frame 401 facing the box opening mechanism 5. The folded packaging carton leans against the box stop. On the left side wall of component 405, the conveying mechanism 402 conveys the packaging carton, causing it to move closer to the box-blocking component 405, ensuring that the box-opening mechanism 5 can normally pick up the packaging carton from the storage mechanism 4; the lifting component 404 is used to drive the second frame 401 and the conveying mechanism 402 to move up or down, changing the height of the packaging carton, and at the same time, rotating the lead screw to move the sliding sleeve with the conveying mechanism 402, changing the distance between the two conveying mechanisms 402, ensuring that the conveying mechanism 402 supports the packaging carton to meet the packaging needs of different sized packaging cartons.

[0028] In this embodiment, as a further optimization, please refer to... Figure 3The box-blocking component 405 includes a frame 4051, which is U-shaped. Limiting plates 4052 are provided on the inner walls of the front and rear sides of the frame 4051. An eighth driving component 4054 (such as a cylinder) is provided on the top of the frame 4051. A baffle 4053 is provided on the moving end of the eighth driving component 4054. When the box-opening mechanism 5 picks up the packaging carton, the eighth driving component 4054 drives the baffle 4053 to block the subsequent packaging carton. After the box-opening mechanism 5 picks up the packaging carton, the eighth driving component 4054 drives the baffle 4053 to move in the opposite direction, releasing the obstruction of the subsequent packaging carton, so that the subsequent packaging carton is transported by the transmission mechanism 402 into the space between the two limiting plates 4052.

[0029] In this embodiment, as a further optimization, please refer to... Figure 8 and Figure 9 The palletizing mechanism 3 includes a first frame 301, with two side baffles 303 symmetrically arranged on the top wall of the first frame 301. A lifting assembly 302 (including a cylinder and a support block on the moving end of the cylinder) is provided on the side wall of the first frame 301. Two support blocks 304 are symmetrically hinged to the inner side wall of the first frame 301, located on the left and right sides of the conveying product, respectively. A spring is provided between the support block 304 and the first frame 301, and the cross-section of the support block 304 is triangular. The feeding conveying mechanism 2... Several products are transferred to the first frame 301 and arranged in a row (the number of products is a preset number). The lifting component 302 drives the row of products to move upward. The rising products contact the inclined surface of the support block 304, causing the support block 304 to rotate and move towards the inner wall of the first frame 301. After the products pass the support block 304, the lifting component 302 resets, and the lifted products fall onto the support block 304 under the action of gravity, where they are supported. Then the operation is repeated to vertically stack the products on the support block 304.

[0030] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
