Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a bag-supporting device and bagging equipment. Background Art

[0002] In the current home appliance manufacturing industry, the plastic bagging process, a critical step in product packaging and protection, plays an essential role in ensuring product safety, cleanliness, and aesthetics during transportation and storage. However, this process has traditionally relied heavily on manual labor, facing significant challenges such as high costs and low efficiency, as well as limited human resources, high labor intensity, and a high rate of human error.

[0003] Specifically, the manual plastic bagging process typically requires workers to individually apply plastic bags to the exterior of home appliances, manually adjusting them to ensure a snug fit and wrinkle-free finish. This process is not only time-consuming and labor-intensive, but also difficult to standardize and maintain. As the home appliance market continues to expand, traditional manual bagging methods are no longer sufficient to meet the demands of large-scale, high-efficiency production. Furthermore, manual operations present certain safety risks, such as the potential for occupational injuries from prolonged, repetitive labor and the risk of product damage from improper operation.

[0004] In view of the above problems, the home appliance manufacturing industry urgently needs an automated and intelligent plastic bag packaging solution to replace the traditional manual operation method. Utility Model Content

[0014] Furthermore, the bag-opening mechanism includes two adsorption members spaced apart along the second direction, and the two adsorption members are arranged inside the two opening members.

[0015] Furthermore, the adjacent adsorption members and / or the expansion members can slide or lock along the second direction.

[0041] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0042] See also Figures 1 to 5 The present invention provides a bag-opening device, comprising two bag-opening mechanisms 100 disposed opposite each other. Each bag-opening mechanism 100 includes an adsorption member 130 and an expansion member 120. The two adsorption members 130 disposed opposite each other are capable of moving in a first direction (i.e., the front-to-back direction in the drawings) to approach and adsorb a plastic film sleeve 610. In the adsorption state, the adsorption members 130 can drive the plastic film sleeve 610 to move outward. It should be noted that the outward movement herein refers to the separation of two opposing side surfaces of the plastic film sleeve 610 in the front-to-back direction, away from each other. The expansion member 120 can drive the plastic film sleeve 610 to move outward in a second direction (i.e., the left-to-right direction in the drawings). It should be noted that the outward movement herein refers to the separation of two opposing side surfaces of the plastic film sleeve 610 in the left-to-right direction, away from each other. The first direction and the second direction are perpendicular to each other. As a result, the plastic film sleeve 610 is expanded in the front-to-back, left-to-right, and left-to-right directions, thereby forming an opening for enclosing items.

[0043] The bag-opening device of the present invention includes two bag-opening mechanisms 100 arranged opposite to each other. The adsorption members 130 of the bag-opening mechanisms 100 arranged opposite to each other can open the plastic film sleeve 610 in a first direction, and the opening members 120 of the bag-opening mechanisms 100 arranged opposite to each other can open the plastic film sleeve 610 in a second direction. The first direction and the second direction are perpendicular to each other, so that the plastic film sleeve 610 can be pulled open in the front, back, left and right directions to form an opening for enclosing items. The two bag-opening mechanisms 100 automatically open the plastic film sleeve 610 and pull the plastic film sleeve 610 to a specified width, thereby realizing fast, accurate and damage-free opening of the plastic bag set, while reducing production costs, improving production efficiency, and reducing human errors and safety hazards, so as to alleviate the technical problems of high cost and low efficiency of household appliance packaging processes in the prior art.

[0044] Specifically, the adsorption component 130 can switch between a first position state and a second position state. When the adsorption component 130 is in the first position state, the adsorption component 130 can be adsorbed on the outer side surface of the plastic film sleeve 610 and move along the front-to-back direction away from the plastic film sleeve 610. When the adsorption component 130 is in the second position state, the adsorption component 130 is separated from the plastic film sleeve 610. Through the reciprocating motion of the adsorption component 130, the plastic film sleeve 610 is pulled open and loosened, thereby completing the opening and installation of the plastic film sleeve 610, and releasing the plastic film sleeve 610 after installation.

[0045] In an optional solution of an embodiment of the present invention, the expansion member 120 includes an expansion drive device 123, which drives the expansion member 120 to move so that the expansion member 120 switches between a state of avoiding the plastic film sleeve 610 and a state of being in contact with the side of the plastic film sleeve 610 away from the adsorption member 130.

[0046] Specifically, when the expansion member 120 is moved to expand, in an optional solution of the embodiment of the present invention, the expansion drive device 123 is a linear motor, which drives the expansion member 120 to move in the direction away from the center of the plastic film sleeve 610 in the second direction; in an optional solution of the embodiment of the present invention, the expansion drive device 123 is a cylinder, which drives the expansion member 120 to move in the direction away from the center of the plastic film sleeve 610 in the second direction; in an optional solution of the embodiment of the present invention, the expansion drive device 123 is a telescopic rod, which drives the expansion member 120 to move in the direction away from the center of the plastic film sleeve 610 in the second direction; those skilled in the art can select a suitable linear drive device or multiple combinations of linear drive devices according to actual needs, usage scenarios and strokes.

[0047] In an optional solution of an embodiment of the present invention, the expansion member 120 includes an expansion drive device 123, which drives the expansion member 120 to rotate so that the expansion member 120 switches between a state of avoiding the plastic film sleeve 610 and a state of abutting the side of the plastic film sleeve 610 facing away from the adsorption member 130. In some embodiments, the expansion drive device 123 is an expansion drive motor, which drives the expansion member 120 to rotate within the plane of the second direction. When the expansion member 120 rotates outward in the second direction, the rotation portion 122 expands the plastic film sleeve 610 laterally through the rotation of the expansion drive device 123. The expansion drive motor drives the expansion member 120 to move in the second direction, thereby completing the expansion of the plastic film sleeve 610.

[0048] Specifically, the expansion drive device 123 can drive the rotating part 122 to rotate from the inside to the outside with the first direction as the axis. It should be noted that the inside here refers to the center of the plastic film sleeve 610, and the outside refers to the direction away from the plastic film sleeve 610. The inside and outside here refer to the relative position relationship, so that the expansion drive device 123 can complete the expansion of the plastic film sleeve 610 in the second direction during the process of driving the rotating part 122 to rotate. When the rotating part 122 rotates to a state of being in contact with the side of the plastic film sleeve 610 away from the adsorption part 130, the plastic film sleeve 610 is between the rotating part 122 and the adsorption part 130, and the rotating part 122 expands the plastic film sleeve 610 in the second direction inside the plastic film sleeve 610, and the adsorption part 130 expands the plastic film sleeve 610 in the first direction outside the plastic film sleeve 610, thereby avoiding interference between the two and forming an opening to the maximum extent to complete the set of the packaged items.

[0049] Specifically, the adsorption component 130 includes an adsorption telescopic rod 132 and a suction cup 131. Specifically, the suction cup 131 is a vacuum suction cup 131. The vacuum suction cup 131 adsorbs and stretches the plastic film cover 610. The adsorption telescopic rod 132 can be extended to make the suction cup 131 close to the outside of the plastic film cover 610 and adsorb the plastic film cover 610. The suction cups 131 relatively arranged along the front and back directions move in the opposite direction, so that the plastic film cover 610 is separated in the front and back directions, thereby forming an opening for covering items.

[0050] In an optional solution of the embodiment of the present invention, the bag-stretching mechanism 100 includes a conveying mechanism 140, which includes a driving roller 142 and a first drive device 141. The first drive device 141 is capable of driving the driving roller 142 to rotate, with the circumference of the driving roller 142 facing the plastic film sleeve 610. As the first drive device 141 drives the driving roller 142 to rotate, the outer circumference of the driving roller 142 rubs against the plastic film sleeve 610. Specifically, the active first drive device 141 is a rotary motor, and the driving roller 142 and the rotary motor cooperate to cause the plastic film sleeve 610 to move downward, thereby pre-conveying the plastic film sleeve 610 and stacking the pre-stretched plastic film sleeve 610 on the support rod to meet the required length of the packaged items.

[0051] In an optional solution of the embodiment of the present invention, the transport mechanism 140 includes a transport telescopic rod 143 connected to the driving wheel 142 . By providing the transport telescopic rod 143 , the driving wheel 142 can be moved closer to or away from the plastic film sleeve 610 .

[0052] In an optional solution of the embodiment of the present invention, a plurality of protrusions and / or grooves are provided on the outer periphery of the active rotating wheel 142, thereby increasing the friction between the active rotating wheel 142 and the plastic film sleeve 610, and better driving the plastic film sleeve 610 to move downward, thereby meeting the length requirements of the packaged items.

[0053] See also Figures 3 to 5 In an optional embodiment of the present invention, the opening member 120 includes a support rod roller 124, which is rotatably connected to the end of the rotating portion 122. The circumference of the support rod roller 124 faces the plastic film sleeve 610, and a sliding space for the plastic film sleeve 610 is defined between the outer circumference of the driving wheel 142 and the outer circumference of the support rod roller 124. By shortening the support rod and adding the support rod roller 124, the support rod roller 124 rotates with the movement of the driving wheel 142, making it easier to pull the plastic bag down and making it more convenient to operate.

[0054] In an optional solution of the embodiment of the present invention, a plurality of protrusions and / or grooves are provided on the periphery of the support rod roller 124 to better drive the plastic film sleeve 610 to move downward, thereby meeting the length requirement of the packaged items.

[0055] See also Figures 1 to 5 In some embodiments, a signal sensor 121 is provided on the rotating portion 122. The signal sensor 121 is electrically connected to the controller to control the feeding of the plastic film cover 610. The signal sensor 121 includes a laser emitter and a laser sensor. The laser emitter and the laser sensor form a pair and are positioned opposite each other. The signal sensor transmits an electrical signal to the film motor 620 based on the difference in reflectivity, thereby controlling the degree of descent of the plastic film cover 610.

[0056] In an optional solution of an embodiment of the present invention, the bag-stretching mechanism 100 includes two stretching members 120 arranged along the second direction, and the two stretching members 120 are arranged on the outside of the adsorption member 130. The bag-stretching mechanism 100 includes two stretching members 120. The two stretching members 120 located on the same side rotate in opposite directions, which can make the plastic film sleeve 610 evenly stressed when stretched, avoiding damage, and avoiding the problem of long stretching stroke and long movement time due to unilateral setting, thereby improving the stretching efficiency.

[0057] In an alternative embodiment of the present invention, the single-sided bag-opening mechanism 100 includes a single opening member 120. In this case, the two opposing opening members 120 move in opposite directions, thereby expanding the plastic film sleeve 610 in the left and right directions. Those skilled in the art may adjust the number and position of the opening members 120 appropriately based on the size of the desired packaged item.

[0058] In an optional solution of the embodiment of the present invention, the bag-opening mechanism 100 includes two adsorption members 130 spaced apart along the second direction, so that the four opening members 120 and the four adsorption members 130 can make the expanded plastic film sleeve 610 have a polygonal shape, which is easier to fit the packaged items. Furthermore, the two adsorption members 130 are arranged on the inner side of the two opening members 120, so that the opening members 120 will not interfere with the adsorption members 130 when they move, thereby avoiding affecting the opening effect. In an optional solution of the embodiment of the present invention, the number of adsorption members 130 can be one, two, or more. Those skilled in the art can reasonably adjust the position and number of adsorption members 130 according to the number of opening members 120 and the shape and size of the items to be packaged.

[0059] In an alternative embodiment of the present invention, adjacent adsorbents 130, or stretching members 120, or both, can slide or lock in the second direction. Thus, by adjusting the distance between adjacent adsorbents 130, or stretching members 120, or between adsorbents 130 and stretching members 120 on the same side, the expansion of plastic film sleeves 610 of different sizes can be adapted, thereby meeting the packaging requirements of items to be packaged in different sizes.

[0060] In an optional solution of an embodiment of the present invention, two adsorption members 130 and two support members 120 located on the same side are respectively combined and installed on the same mounting frame (not shown in the figure), and one mounting frame is driven by a transverse motor 112, so as to facilitate the movement of the adsorption members 130 and support members 120 located on the same side that are symmetrical about the first direction, and can reduce the number of transverse motors 112 and reduce costs.

[0061] See also Figures 1 to 7 The present invention also provides a bagging device, which includes a frame 300 and the above-mentioned bag-holding device. The bag-holding mechanism 100 is respectively installed on the opposite sides of the frame 300. Specifically, the bagging device includes four vertical rows 310 arranged in the vertical direction, and horizontal rows arranged in the first direction and horizontal rows arranged in the second direction are respectively provided at the top and bottom of the four vertical rows 310. The two groups of horizontal rows connect the four vertical rows 310 together to form a bagging area. The bag-holding mechanism 100 is arranged on two vertical rows adjacent to each other in the second direction. The connecting frame 320 between the frames 310 and 310 is provided with a vertical motor 111 at each end of the connecting frame 320. The connecting frame 320 is slidably connected to the vertical frame 310. The vertical motor 111 can drive the connecting frame 320 to move up and down vertically and lock on the vertical frame 310. The horizontal frame at the top of the frame 300 is provided with a feeding device 600. The feeding device 600 includes a roll formed by the convolution of the plastic film sleeve 610 and a film motor 620 that drives the roll to rotate. The film motor 620 controls the downward conveyance and stopping of the plastic film sleeve 610. A cutting device 200 and a heat sealing device 500 are provided below the feeding device 600. The feeding device 600, the cutting device 200, and the heat sealing device 500 are all electrically connected to the controller. The controller can control the cutting device 200 to cut the roll material, and the controller can control the heat sealing device 500 to heat seal the end of the plastic film sleeve 610, thereby forming a closed port to seal and protect the packaged product to prevent contamination.

[0062] The bagging device of the present invention includes two bagging mechanisms 100 arranged opposite to each other. The adsorption members 130 of the bagging mechanisms 100 arranged opposite to each other can open the plastic film sleeve 610 in a first direction, and the opening members 120 of the bagging mechanisms 100 arranged opposite to each other can open the plastic film sleeve 610 in a second direction. The first direction and the second direction are perpendicular to each other, so that the plastic film sleeve 610 can be pulled open in the front, back, left and right directions to form an opening for set items. The two bagging mechanisms 100 automatically open the plastic film sleeve 610, thereby pulling the plastic film sleeve 610 to a specified width. The bagging device includes a bagging device that can slide and position on the frame 300. Since the bagging mechanism 100 can move up and down and lock in the vertical direction on the frame 300 , thereby pulling the plastic film sleeve 610 to cover the items to be packaged, a feeding device 600 is provided on the top of the frame 300, and a cutting device 200 and a heat sealing device 500 are provided below the feeding device 600. The cutting device 200 can complete the cutting of the plastic film sleeve 610 when the plastic film sleeve 610 is stretched to a preset position, and the heat sealing device 500 simultaneously heats the end of the plastic film sleeve 610 to achieve plastic sealing. The feeding device 600, the cutting device 200 and the heat sealing device 500 are all electrically connected to the controller, so that the plastic bag set can be opened quickly, accurately and without damage, while reducing production costs, improving production efficiency, and reducing human errors and safety hazards, so as to alleviate the technical problems of high cost and low efficiency of household appliance packaging processes in the prior art.

[0063] Specifically, the bagging equipment also includes a base 400, which is provided with a conveyor track. The conveyor track can carry a material transfer tray 430. The material transfer tray 430 can slide along the conveyor track in a second direction to complete the transportation of the items to be bagged. An image acquisition device 410 and a limit device 420 are provided on the conveyor track along the material transportation direction. Specifically, the image acquisition device 410 is a high-speed camera, and the limit device 420 is a limiter. The frame 300 is provided with a detection switch 330. Specifically, the detection switch 330 is a laser switch, which is electrically connected to the controller. This achieves automatic identification and start-stopping of the bagging equipment, improves work efficiency, and ensures the safety of operators.

[0064] The bagging equipment of the present invention operates as follows: the controller inputs the product size to be packaged, automatically adjusts the width of the horizontal motor 112, and sets the stroke of the vertical motor 111. The controller determines the process parameters for the bagging operation based on the product parameters. These process parameters include, but are not limited to, the size adjustment between two adjacent expansion members 120 and two adsorption members 130 on the connecting rack 320, the stroke of the motor, the stroke of each telescopic rod, the size of the coil, and the coil operating parameters. When the product is detected entering the bagging area, the bagging operation is performed based on the set bagging process parameters.

[0065] First, the material transfer tray 430 carries the product and flows along the transport line. When the laser switch senses that the product has passed the laser switch, the controller determines that the product has arrived. The controller receives a signal to start the entire device. The film motor 620 receives an electrical signal to start, transporting the roll material downward to the laser sensor position, blocking the laser. The laser sensor transmits an electrical signal to the film motor 620 to stop transport. After the film motor 620 stops, it transmits a signal to the adsorption telescopic rod 132 to extend, docking relative to the two vacuum suction cups 131, and starts air pressure adsorption of the plastic film sleeve 610. At the same time, it shortens backward to the initial position, completing the expansion of the plastic film sleeve 610 in the first direction. The signal is then transmitted to the expansion drive device 123 to start, rotating the support rod 180 degrees, and expanding the plastic film sleeve 610. In some embodiments, the controller also needs to transmit a signal to the rotary motor telescopic rod to extend the rotary wheel to press the plastic film sleeve 610. The rotary motor and the film motor 620 are started simultaneously to pre-stack the plastic film sleeve 610 on the support rod. When the length reaches a sufficient length, the operation is stopped. A signal is transmitted to the heat sealing device 500 and the cutter to operate to seal and cut the plastic film sleeve 610. At this time, the stretched and sealed plastic film sleeve 610 is obtained and the next step of the set operation can be carried out.

[0066] The connecting rack 320 moves downward, enabling automated bagging. A high-speed camera monitors the bagging process, which is then evaluated by an analyzer, sending a signal to activate a limiter or alarm. The limiter controls the movement of the material transfer tray 430, stopping and starting the transport line.

[0067] The limiter detects the arrival of the material transport pallet, the transport line stops moving and transmits a signal; the vertical movement motor is started, the entire bag-holding device moves downward, and as the bag-holding device continues to move downward, the power to the wheel motor is cut off. As the bag-holding device moves downward, the wheel rotates, and the pre-stacked plastic film sleeve 610 is gradually stretched; the numerical motor reaches the preset position and transmits a signal, the telescopic rod of the wheel motor shortens to the initial position, the opening drive device 123 rotates the rod 180 degrees in the opposite direction, and the vacuum suction cup 131 releases the plastic film sleeve 610. The bag-holding device completes its work, the movement motor is started and returns to the initial position, and the high-speed camera transmits an image to the controller to judge the bagging effect. If:

[0068] 1. When the bagging effect meets the requirements, the limiter is released, the transport line is started, and the product continues to flow to the next process;

[0069] 2. If the bagging effect does not meet the requirements, the vertical motor 111 moves upward and the rotary motor starts again to recover the released plastic film sleeve 610, and move the entire bag-holding device upward to the initial position. The bag-holding device is adjusted accordingly according to the analysis results of the processor, and the bagging action is completed again until the bagging effect meets the requirements.

[0070] The bagging device of the present invention comprises a feeding device 600 composed of a rolled plastic film sleeve 610 and a film motor 620, and a sealing and cutting mechanism composed of a cutting device 200 and a heat-sealing device 500, located above the horizontal rack of the frame 300. A vertical rail and a laser switch are provided on the side of the vertical rack 310, and a bag-supporting mechanism 100 is provided on a connecting rack 320 that can move along the vertical rack 310. A bagging area is formed within the frame 300, and is equipped with a material transfer tray 430, a limiter, and a bagging effect feedback mechanism. The entire bagging device, through its control method, enables automatic bagging of household appliances. Application of the present invention and its control method enables rapid and automatic bagging of household appliances, saving labor, improving efficiency, and reducing costs.
