The clamping structure ensures that the material bag will not tip over. Simultaneously, two bag-holding structures are arranged on both sides of the column frame, employing a double-clamping station to simultaneously clamp and transfer the bag in a single longitudinal movement, achieving high efficiency.

Description

Technical Field

[0001] This utility model relates to the field of packaging and control technology, and in particular to a rapid bag-holding and transferring mechanism. Background Technology

[0002] In industries that require packaging materials, such as sugar, food, feed, chemical, starch, pharmaceutical, fertilizer, and nano-calcium carbonate industries, powders and granules need to be bagged, for example, using inner and outer bags as packaging bags.

[0003] For example, the Chinese invention patent "A Fully Automatic Production Line for Packaged Inner and Outer Bag Material Packaging, Publication No. CN110697149A" includes a frame, a bag placing frame, a bag picking mechanism, a bag placing mechanism, a rotating mechanism, a loading hopper, a bag clamping mechanism, a bag supporting mechanism, a bag inserting mechanism, a packaging scale, a discharge hopper, a discharge sealing mechanism, an air squeezing mechanism, an inner bag sealing mechanism, an inner bag clamping and moving mechanism, an inner bag inserting mechanism, an outer bag opening mechanism, a sewing and conveying mechanism, a sewing machine, a belt conveyor, a vision camera, and a rejection mechanism. It can operate smoothly in dusty environments without jamming during shrinkage and expansion; the sewing and conveying mechanism clamps both sides of the sewing thread at the opening of the outer bag of the packaged bag for sewing, preventing misalignment; the vision camera identifies defective products after sewing, which are then rejected by the rejection mechanism, improving the product pass rate.

[0004] As mentioned above, after the packaging bag is filled, it is usually pushed to the inner bag insertion position by the lower conveyor, and then the packaging bag and its upright opening are guided into the sewing machine. If the conveyor belt runs too fast, the material bag on it will tilt and fall down. Therefore, the efficiency is low due to the limited pushing speed of the conveyor. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a rapid bag-holding and transferring mechanism that can achieve the clamping and transfer of material bags.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rapid bag-holding and transferring mechanism includes a moving component, which comprises a sub-frame, a guide rail assembly, a sliding seat, and a moving drive component. The guide rail assembly is arranged longitudinally, with a base and the sub-frame mounted at both ends. The moving drive component is mounted on the base, and the sliding seat is slidably connected to the guide rail assembly. The sliding seat is connected to the moving drive component and can reciprocate longitudinally between an initial position and a transfer position under the drive of the moving drive component. It also includes a column frame and a bag-holding assembly. Column frames are mounted on the left and right ends of the sliding seat, and each column frame is divided into front and rear longitudinal sections. The sliding seat is equipped with a bag-holding assembly. The left and right ends of the column frame and the bag-holding assembly form a moving channel to transfer the material bag. The bag-holding assembly includes a bag-holding plate frame, a bag-holding support, a bag-holding track, and a bag-holding drive component. The bag-holding support is installed on the sliding seat and can move laterally along the bag-holding track. The bag-holding support is connected to the bag-holding drive component and can move laterally back and forth under the drive of the bag-holding drive component. The two oppositely arranged bag-holding plates can move laterally inward and protrude into the moving channel a certain distance as the bag-holding support moves to compress and hold the material bag tightly.

[0008] The bag-holding track includes a linkage assembly and a crank arm. The bag-holding support is hinged to the sliding seat via the linkage assembly. The crank arm is rotatable in both the horizontal and vertical planes and is connected to the sliding seat. One end of the crank arm is connected to the bag-holding support, and the other end of the crank arm is connected to the telescopic end of the bag-holding drive component. The fixed end of the bag-holding drive component is connected to the sliding seat. The bag-holding support can reciprocate laterally under the pushing action of the crank arm when the bag-holding drive component drives the crank arm to rotate. This achieves the connection of the bag-holding track.

[0009] The bag-holding drive unit is a standard cylinder. The moving drive unit is a moving motor, which is connected to the sliding seat via a drive wheel assembly and a transmission push rod; this achieves the drive connection. The sliding seat is connected to the guide rail assembly via linear bearings, and the guide rail assembly consists of four longitudinally extending straight shafts; this achieves the guide rail connection. A slide table is installed on the base and sub-frame, located at the bottom of the moving channel and above the sliding seat, with its vertical height lower than the bag-holding plate frame; this supports the material bag and serves as a slide rail to the bag-sealing position, reducing the clamping force of the bag-holding assembly and the pushing force required by the moving drive unit.

[0010] As described above, the bag-holding frame is moved laterally inward by the bag-holding drive components of two oppositely arranged bag-holding assemblies, pressing and clamping the material bag. Then, the moving assembly, driven by the moving drive components, moves longitudinally back and forth between the initial position and the transfer position, thereby realizing the clamping and transfer of the material bag. At the same time, two bag-holding structures are arranged on both sides of the column frame, adopting a double-clamping station to clamp and transfer the bag simultaneously in one longitudinal movement, which has high efficiency.

[0011] Based on the aforementioned solution, in an improved version, to address the issue of low clamping force caused by the relatively smooth clamping surface of the clamping plate frame, the clamping assembly further includes clamping blocks. Clamping blocks are installed at both longitudinal ends of the inner end face of the clamping plate frame, arranged vertically. The protruding arrangement of the clamping blocks at both longitudinal ends of the plate frame enhances the clamping force. The longitudinal ends of the clamping plate frame are laterally inclined inwards to improve the limiting and clamping fixing effect.

[0012] Based on the aforementioned solution, in an improved version, to address the potential tilting of the material bag during movement due to the low height of the sealing structure frame and the bag-holding block, the bag-holding and transferring mechanism further includes a bag-protecting assembly. This assembly comprises a left bag-protecting section and a right bag-protecting section, positioned directly above the two opposing bag-holding assemblies. The left bag-protecting section includes a left bag-protecting drive, a bag-protecting elastic element, and a left bag-protecting pressure rod. The fixed end of the left bag-protecting drive is located on the left-side column frame, and its telescopic end is connected to the left bag-protecting pressure rod via the bag-protecting elastic element. The left bag-protecting pressure rod extends longitudinally. The right bag-protecting section includes a right bag-protecting drive and a right bag-protecting pressure rod. The fixed end of the right bag-protecting drive is located on the right-side column frame, and its telescopic end is connected to the right bag-protecting pressure rod. The right bag-protecting pressure rod extends longitudinally. Both the left and right bag-protecting drives are three-axis cylinders. In this way, the protective bag driving component pushes the protective bag pressure bars of the same group to approach each other, thereby compressing and clamping the material bag, and the protective bag elastic component plays a buffering role.

[0013] Based on the aforementioned solution, in an improved version, to address the issues of air extrusion within the material bag and tight sealing of both sides of the bag opening, the bag-holding and transfer mechanism further includes an air-explosion assembly. This assembly is positioned longitudinally at the front of the column frame and comprises a left air-explosion section and a right air-explosion section. The left and right air-explosion sections are respectively positioned directly above two opposing bag-holding assemblies. The left air-explosion section includes a left air-explosion drive component, an air-explosion elastic component, and an air-explosion pressure rod. The fixed end of the left air-explosion drive component is located on the left side of the column frame, and the telescopic end of the left air-explosion drive component is connected to the left air-explosion pressure rod via the air-explosion elastic component. The left air-explosion pressure rod extends longitudinally. The right air-explosion section includes a right air-explosion drive component and a right air-explosion pressure rod. The fixed end of the right air-explosion drive component is located on the right side of the column frame, and the telescopic end of the right air-explosion drive component is connected to the right air-explosion pressure rod. The right air-explosion pressure rod extends longitudinally. The left and right air-explosion pressure rods have identical structures and are bow-shaped, forming a break in the middle of the extrusion surface as an air outlet. Both the left and right extrusion drive components are three-axis cylinders. The extrusion drive components push the extrusion bars in the same group closer together, compressing and pressing them tightly against the bag opening to expel the gas inside. The extrusion elastic component acts as a buffer.

[0014] Based on the aforementioned solution, in an improved version, to address the potential tilting issue before the bag is firmly held by the bag-holding assembly, the bag-holding and transferring mechanism further includes guardrail assemblies. Guardrail assemblies are installed on both the left and right sides of the sliding seat's movement channel. Each guardrail assembly includes a vertical rod, a horizontal screw, and longitudinal rails. The bottom end of the vertical rod is installed on the sliding seat, and the top end of the vertical rod is fitted with a horizontally extending horizontal screw. The inner end of the horizontal screw is fitted with a nut to adjustably connect to the longitudinal rails, allowing for adjustment of their lateral extension length. The longitudinal rails extend longitudinally. Both ends of the longitudinal rails tilt outwards laterally, serving a guiding function. This allows the material bag to stand upright on the sliding table next to the longitudinal rails. The two extended longitudinal rails provide limiting and support functions, and the horizontal nut and its adjustable extension length allow for adjustment of the spacing between the longitudinal rails according to the size of the material bag. In a preferred embodiment, the two ends of the longitudinal guardrail are respectively positioned between the two longitudinal ends of the bag-holding frame. The two bag-holding blocks of the bag-holding assembly include a short bag-holding block and a long bag-holding block with different heights. The short bag-holding block is located longitudinally inside the long bag-holding block. The longitudinal guardrail is higher than the short bag-holding block and lower than the long bag-holding block in vertical height. This combination of the bag-holding assembly's position provides good support and ensures that the material bag will not tip over.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] This utility model's rapid bag-holding and transfer mechanism consists of two opposing bag-holding components forming a bag-holding structure. A bag-holding drive unit drives the bag-holding plate to move laterally inward, compressing and clamping the material bag. Then, a moving component, driven by the moving drive unit, moves longitudinally back and forth between the initial position and the transfer position, thereby achieving the clamping and transfer of the material bag. Simultaneously, two bag-holding structures are arranged on both sides of the column frame, employing a double-clamping station to simultaneously clamp and transfer the bag in a single longitudinal movement, resulting in high efficiency.

Detailed Implementation

[0019] Example 1

[0020] See Figures 1-7 The rapid bag-carrying and transferring mechanism of this embodiment 1 includes a moving component, which includes a sub-frame 122, a guide rail assembly 123, a sliding seat, and a moving drive component. The guide rail assembly 123 extends longitudinally, and a base and the sub-frame 122 are installed at both ends of the guide rail assembly 123. The moving drive component is installed on the base, and the sliding seat is slidably connected to the guide rail assembly. The sliding seat is connected to the moving drive component and can move longitudinally back and forth between the initial position and the transfer position under the drive of the moving drive component. It also includes a column frame and a bag-carrying assembly 124. Column frames (left column frame 1218 and right column frame 1228) are respectively installed at the left and right ends of the sliding seat. A bag-carrying assembly is installed on the front and rear sides of each column frame. The bag assembly 124 consists of identical and mirror-arranged uprights at both ends, and identical and mirror-arranged bag-holding assemblies at both ends. A moving channel is formed between the uprights at both ends of the sliding seat and the bag-holding assemblies to facilitate the flow of material bags 1238. The bag-holding assembly includes a bag-holding plate frame, a bag-holding support, a bag-holding track, and a bag-holding drive component 1241. The bag-holding support is installed on the sliding seat and can move laterally along the bag-holding track. The bag-holding support is connected to the bag-holding drive component and can move laterally back and forth under the drive of the bag-holding drive component. As the bag-holding support moves, the two relatively arranged bag-holding plates can move laterally inward and protrude into the moving channel a certain distance to compress and hold the material bags 1238 tightly.

[0021] Among them, the moving drive component and the bag-holding drive component are existing equipment, such as motor drive, hydraulic cylinder drive, pneumatic cylinder drive, etc., with corresponding air source and solenoid valve, controller connection and control, etc. The connection and control of these components all adopt existing technologies. This application applies them and combines them with guide rail assembly and bag-holding plate frame and other related mechanical structures to achieve this.

[0022] The moving drive unit uses a moving motor, which is equipped with a motor cover 1213 and mounted on a base 1214. The motor cover 1213 is connected (hinged) to a sliding seat via a drive wheel set 15 and a transmission push rod. A zero-point mounting base 1233 is installed inside the motor cover to mount a zero-point detection sensor. These are all existing technologies and will not be described in detail here. Thus, by rotating the moving motor forward and backward, the drive gear set drives the transmission push rod to longitudinally push the sliding seat forward and backward, achieving a drive connection with the sliding seat.

[0023] The sliding seat includes a frame composed of a square tube base 1219 and a mounting platform on which a column frame, etc., is installed. To protect bearings, a protective plate (screw-connected) is configured to form a hollow box structure, which can be made of ordinary carbon steel or AISI 304 material. To improve sliding performance, a guide rail assembly is connected via linear bearings 1223. The guide rail assembly consists of four longitudinally extending straight shafts, with shaft sealing plates 1235 installed at the ends of the straight shafts. Other components may include a bellows-style connecting cover 1226 and a bearing dust cover 1227. This achieves the guide rail connection. Furthermore, a bridge-type cable chain 1221 is mounted on it and is bolted to the column frame and the external application equipment frame via a first cable chain connecting bracket 125 and a second cable chain connecting bracket 127 at the ends.

[0024] The support frame consists of two square tubes arranged opposite each other, with the electrical box 1231 connected between them by a third pad 1229 and bolts. A flange plate is welded to the bottom of the support frame, and the flange plate is bolted to the middle of the sliding seat in conjunction with the second pad 1216 and the fourth pad 1230. It can be made of 6061 aluminum alloy or AISI304 material.

[0025] The bag-holding track can adopt a track structure such as guide rail assembly 123, in which case the bag-holding drive component is arranged laterally; alternatively, a rotatable crank clamping structure can be adopted, in which case the bag-holding drive component can be arranged vertically. This application uses the rotatable crank clamping structure as an example. The bag-holding track includes a connecting rod assembly and a crank arm 1242. The bag-holding support is hinged to the sliding seat via the connecting rod assembly and bearing. The crank arm 1242 is rotatably connected to the sliding seat in both the lateral and vertical planes (hinged via a rotating shaft, bearing, and bearing seat). One end of the crank arm 1242 is connected to the bag-holding support, and the other end is connected (hinged) to the telescopic end of the bag-holding drive component 1241. The fixed end of the bag-holding drive component 1241 (hinged to the top of the stand via a sleeve shaft and bearing seat, the stand being welded or bolted) is connected to the sliding seat. The bag-holding support can be pushed by the crank arm to move laterally when the bag-holding drive component drives the crank arm to rotate; thus, the bag-holding track connection is achieved. As shown in the figure, the bag assembly is assembled independently for easy disassembly and assembly. The bag base supports the structure and is bolted to the sliding seat. The bag drive components, connecting rods, etc. are welded or bolted to the bag base. 6061 aluminum alloy or AISI304 material can be used.

[0026] The gripping drive unit 1241 uses a standard cylinder to obtain a strong gripping force. The corresponding air source, solenoid valve, controller connection and control are all existing technologies and will not be described in detail here.

[0027] Material bags 1238 can be directly held by the bag-holding assembly. In this case, the weight of the material bag is held and supported by the bag-holding assembly, and there is no relative movement between the material bag and the sliding seat. Alternatively, the material bag can fall onto the sliding seat mounting platform and be held by the bag-holding assembly. In this case, the weight of the material bag is supported by the mounting platform and held by the bag-holding assembly, and there is no relative movement between the material bag and the sliding seat. Alternatively, the material bag can fall onto an external dedicated slide and be held by the bag-holding assembly. In this case, the weight of the material bag is supported by the dedicated slide and held by the bag-holding assembly, and there is relative movement between the material bag and the sliding seat. This application uses an external dedicated slide structure as an example. A slide is installed (connected by bolts) on the base 1214 and sub-frame 122. The slide is located at the bottom of the moving channel and above the sliding seat, with its vertical height lower than the bag-holding plate frame. It can be made of 6061 aluminum alloy or AISI304 material. This design supports the material bag and allows it to slide towards the sealing position. When the material bag is heavy and the slide is relatively smooth, it helps reduce the clamping force of the bag-holding assembly and the pushing force required by the moving drive components. The base 1214 and sub-frame 122 are mounted on the ground with a base plate 1236, etc.

[0028] The working process of this rapid bag-holding and transferring mechanism is as follows: During installation, the sliding seat is installed on the guide rail assembly, the guide rail assembly is installed on the base and sub-frame, the moving motor assembly is installed, and the bag-holding assembly is installed. In use, the base serves as the front end, and the sub-frame as the rear end. The feeding position, sealing position, and transfer position are arranged sequentially from front to back. The initial positions of the two sets of bag-holding structures correspond to the feeding and sealing positions, respectively. After the feeding mechanism feeds the bag, it falls onto the sliding table. Then, the bag-holding assembly is triggered to tighten the bag inwards. Next, the moving motor is triggered to push the sliding seat from the initial position to the rear end to the transfer position. The mechanism stops when the two sets of bag-holding structures have moved to the sealing and transfer positions, respectively. Then, the bag-holding assembly is triggered to release the bag outwards. Finally, the moving motor is triggered to push the sliding seat back to the front end, returning to the initial position. This cycle repeats as described above. Thus, with two sets of bag-holding structures, the front bag-holding structure moves the material bag from the feeding position to the sealing position, and the rear bag-holding structure moves the material bag from the sealing position to the transfer position, enabling double bag transfer. A rearward-extending conveyor 121 is arranged at the transfer position, transporting the material bag to the next process via the conveyor belt and guardrail. A proximity switch is installed on the proximity switch base 1232 to detect position information; the proximity switch and its connection control are existing technologies.

[0029] As described above, a bag-holding structure is formed by two opposing bag-holding components. The bag-holding drive unit moves the bag-holding plate laterally inward to compress and hold the material bag. Then, driven by the moving drive unit, the bag-holding component moves longitudinally back and forth between the initial position and the transfer position, thereby achieving the clamping and transfer of the material bag. The clamping structure ensures that the material bag will not tip over. Simultaneously, two bag-holding structures are arranged on both sides of the column frame, employing a double-clamping station to simultaneously clamp and transfer the bag in a single longitudinal movement, achieving high efficiency.

[0030] Example 2

[0031] Based on Example 1, Example 2 has better clamping performance.

[0032] like Figures 1-7 As shown, to address the issue of low clamping force caused by the smoothness of the clamping surface of the clamping plate, the clamping assembly also includes clamping blocks. Clamping blocks are installed at both ends of the longitudinal direction of the inner end face of the clamping plate. Two clamping blocks with identical structures or one long and one short clamping block, as shown in the figure, can be used. The clamping blocks are arranged vertically, and the protruding arrangement of the clamping blocks at both ends of the plate increases the clamping force. Furthermore, the longitudinal ends of the clamping plate are inclined laterally inwards, which improves the limiting and clamping fixation effect.

[0033] Example 3

[0034] Based on Example 1 or Example 2, Example 3 has a protective bag structure.

[0035] like Figures 1-7As shown, to address the issue of potential tilting of material bags during movement due to the low height of the sealing structure and the low height of the bag-holding blocks, the bag-holding and transferring mechanism also includes a bag-protecting assembly. This assembly is used in conjunction with the bag-holding structure, and one or two bag-protecting assemblies can be arranged as needed. As shown in the figure, this application uses the arrangement of two bag-protecting assemblies as an example. The bag-protecting assembly includes a left bag-protecting section 129 and a right bag-protecting section 128. The left bag-protecting section 129 and right bag-protecting section 128 are respectively arranged directly above the two opposing bag-holding assemblies 124. The left bag-protecting section 129 includes a left bag-protecting drive component, a bag-protecting elastic component, and a left bag-protecting pressure rod. The fixed end of the left bag-protecting drive component is connected to the left-side column frame (left column frame 1218) via a cylinder seat assembly (including a cylinder seat and a first pad 126, both sets of structures are identical) and bolted together. The telescopic end of the left bag-protecting drive component... The left protective bag pressure rod is connected to the elastic element of the protective bag. The left protective bag pressure rod extends longitudinally. The right protective bag part 128 includes a right protective bag drive and a right protective bag pressure rod. The fixed end of the right protective bag drive is connected to the right column frame (right column frame 1228) by bolts through a cylinder seat kit (one set includes cylinder seat "12172" and fifth pad 1237, and another set includes cylinder seat '12171, etc., with the same structure). The telescopic end of the right protective bag drive is connected to the right protective bag pressure rod. The right protective bag pressure rod extends longitudinally.

[0036] Both the left and right protective bag drive components are three-axis cylinders, and the corresponding air sources, solenoid valves, and controller connections are existing technologies, which will not be elaborated here. Thus, the protective bag drive components push the protective bag pressure bars in the same group closer together to compress and clamp the material bag, while the elastic components of the protective bags act as a buffer.

[0037] Example 4

[0038] Based on Example 1, Example 2, or Example 3, Example 4 has an extrusion structure.

[0039] like Figures 1-7As shown, to address the issues of extruding air from the material bag and ensuring it adheres tightly to both sides of the bag opening, the bag-holding and transferring mechanism also includes an air-explosion assembly. This assembly is positioned longitudinally at the front of the column frame and includes a left air-explosion section 1220 and a right air-explosion section 1222. These two sections are positioned directly above two opposing bag-holding assemblies 124. The left air-explosion section 1220 includes a left air-explosion drive, an air-explosion elastic element, and an air-explosion pressure rod. The fixed end of the left air-explosion drive is connected via a cylinder seat assembly (see the aforementioned...). The left column frame (left column frame 1218) is bolted to the right. The telescopic end of the left extrusion drive is connected to the left extrusion rod via an extrusion elastic element. The left extrusion rod extends longitudinally. The right extrusion part 1222 includes a right extrusion drive and a right extrusion rod. The fixed end of the right extrusion drive is bolted to the right column frame (right column frame 1228) via a cylinder seat assembly (including cylinder seat 1217 and pad). The telescopic end of the right extrusion drive is connected to the right extrusion rod, which extends longitudinally. The left and right extrusion rods have the same structure and are bow-shaped, forming a break in the middle of the extrusion surface as an air outlet.

[0040] Both the left and right extrusion drive components are three-axis cylinders, and the corresponding air sources, solenoid valves, and controller connections are existing technologies, which will not be elaborated here. The extrusion drive components push the extrusion rods in the same group closer together, compressing and pressing them tightly against the bag opening to expel the gas inside. The extrusion elastic component acts as a buffer.

[0041] Example 5

[0042] Based on Embodiment 1, Embodiment 2, Embodiment 3, or Embodiment 4, Embodiment 5 includes a guardrail structure.

[0043] like Figures 1-7 As shown, in order to solve the problem of possible tilting before being held tightly by the bag-holding assembly, the bag-holding transfer mechanism also includes a guardrail assembly 1210. Guardrail assemblies 1210 are installed on the left and right sides of the sliding seat's moving channel. The guardrail assembly 1210 includes a vertical rod, a horizontal screw, and a longitudinal guardrail. The bottom end of the vertical rod is installed on the sliding seat, and the top end of the vertical rod is installed with a horizontally extending horizontal screw. The horizontal outer end of the horizontal screw is connected or welded to it with a matching nut. The horizontal inner end of the horizontal screw is matched with a limit nut and a locking nut to adjustably connect to the longitudinal guardrail, so that its horizontal extension length can be adjusted. The longitudinal guardrail is arranged to extend longitudinally.

[0044] The longitudinal ends of the vertical rails slope outward laterally to provide guidance. This allows the material bag to stand upright on the sliding table or sliding seat next to the vertical rails. The two extended vertical rails provide positioning and support, and the adjustable length of the horizontal screw and nut allows for adjustment of the spacing between the vertical rails according to the size of the material bag.

[0045] In a preferred embodiment, the two ends of the longitudinal guardrail are respectively positioned between the two longitudinal ends of the bag-holding frame. At this time, the two bag-holding blocks of the bag-holding assembly include a short bag-holding block and a long bag-holding block with different heights. The short bag-holding block is located longitudinally inside the long bag-holding block. The longitudinal guardrail is higher than the short bag-holding block and lower than the long bag-holding block in vertical height. This combination of the bag-holding assembly position provides good support and ensures that the material bag will not tip over.

[0046] It should be noted that the examples of the above embodiments can preferably be combined with one or more of each other according to actual needs, and the accompanying drawings of multiple examples adopt a set of combined technical features, which will not be described in detail here.

[0047] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
