In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "linking" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral connection; can be mechanical connection, can also be electrical connection; can be direct connection, can also be indirect connection through intermediate medium, can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] As Figures 1 to 5 shown, the present application provides a kind of outer packaging equipment, comprising: conveying device, clamping device, turnover device and bag cutting device 500;Conveying device includes rack 100 and the transmission assembly 200 being arranged on rack 100, clamping device includes mounting bracket 310 and the clamp assembly 320 being connected with mounting bracket 310, clamp assembly 320 bag clamp driving part and clamp being connected with clamp driving part, clamp driving part is used to control the opening and closing of clamp, clamp is used to clamp the end of the outer packaging bag of raw material, clamp driving part is connected with mounting bracket 310;Turnover device includes turnover driving part being connected with rack 100 and turnover arm being connected with turnover driving part, one end of turnover arm is rotatably connected with rack 100, the other end of turnover arm is connected with mounting bracket 310, turnover driving part is used to drive turnover arm to rotate;Bag cutting device 500 includes base 501, bag cutting driving part being arranged on base 501 and tool 503 being connected with bag cutting driving part, base 501 is connected with mounting bracket 310, bag cutting driving part (can adopt air cylinder) is used to drive tool 503 movement to cut open the outer packaging bag of bagged raw material 800.

[0029] In the working process of the outer packaging bag removing device provided in the embodiment, the bagged raw material 800 is placed on the conveying assembly 200, and the conveying assembly 200 can be controlled to work by the control system 600 to drive the bagged raw material 800 to move towards the clamping device. In the initial state, the clamp is in the open state, and under the conveying of the conveying assembly 200, the first edge of the outer packaging bag of the bagged raw material 800 can first reach the opening of the clamp. At this time, the clamp driving part in the clamping device drives the clamp to close to clamp the edge of the first end. The turnover driving part works to drive the turnover arm to rotate around the center of the rotating connection of the rack 100, and the turnover arm rotates by a certain angle, thereby lifting the mounting rack 310 and further lifting the clamp assembly 320, and then the clamp lifts the first end of the outer packaging bag. In the lifting process of the first end of the outer packaging bag, a gap is generated between the inner packaging bag and the outer packaging bag of the bagged raw material 800. When the outer packaging bag is lifted to the position, the cutter driving part 502 drives the cutter 503 to move to cut the first end of the outer packaging bag. The turnover driving part drives the turnover arm to reset, so that the bagged raw material 800 returns to the conveying assembly 200 again, and the clamp driving part makes the clamp open. Then, the edge of the second end of the bagged raw material 800 moves towards the clamping device, and when the edge of the second end reaches the opening of the clamp, the clamp driving part controls the clamp to close to clamp the edge of the second end. At this time, the turnover driving part works to drive the turnover arm to rotate by a certain angle, thereby lifting the edge of the second end. The first end of the outer packaging bag has been cut, so that in the lifting process of the second end, the raw material with the inner packaging bag slides out of the cut to the conveying assembly 200, and thus the outer packaging of the bagged raw material 800 is removed.

[0030] The outer packaging bag removing device provided in the embodiment can reduce the amount of manual labor, improve the automation degree of outer packaging removal, and thus improve the production efficiency. In the bag removal process, the end of the outer packaging bag can be cut after a gap is generated between the outer packaging bag and the inner packaging bag, so as to avoid cutting the inner packaging bag and protect the sealing and integrity of the raw material. The outer packaging removing device provided in the embodiment has a simple structure and is easy to maintain.

[0031] It should be noted that the first end and the second end of the outer packaging bag are oppositely arranged.

[0032] The clamping device can be one, and at this time, the edge of the second end of the outer packaging bag of the bagged raw material 800 can be turned to the clamping device by manual operation, or a mechanical hand can be arranged on one side of the conveying assembly 200 to turn the bagged raw material 800.

[0033] As an optional solution, as shown in FIG. 6, the outer packaging bag removing device can further include a conveying assembly 200, and the conveying assembly 200 can be arranged on the rack 100. Figure 1As shown, the clamping device includes a first clamping device 301 and a second clamping device 302 (i.e., the number of clamping devices is at least two, one of which is the first clamping device 301 and the other of which is the second clamping device 302), and correspondingly, the mounting frame 310 and the clamping assembly in the first clamping device 301 are respectively a first mounting frame and a first clamping assembly, and the clamp driving member and the clamp in the first clamping assembly are respectively a first clamp driving member and a first clamp. Similarly, the mounting frame 310 and the clamping assembly in the second clamping device 302 are respectively a second mounting frame and a second clamping assembly, and the clamp driving member and the clamp in the second clamping assembly are respectively a second clamp driving member and a second clamp; the first clamping device 301 and the second clamping device 302 are both connected with the turnover arm, the first clamping clamp is used for clamping the edge of the first end of the outer packaging bag, and the second clamp is used for clamping the edge of the second end of the outer packaging bag.

[0034] In this embodiment, the two edges of the two ends of the outer packaging bag can be sent to the corresponding clamping device step by step by the conveying assembly 200, for example: the conveying assembly 200 first conveys the bagged raw material 800 to the direction close to the first clamping device 301, so that the edge of the first end of the outer packaging bag is placed in the opening of the first clamp in the first clamping device 301, and then the subsequent process is performed to complete the opening of the first end of the outer packaging bag; when the bagged raw material 800 after opening falls to the conveying assembly 200 again, the conveying assembly 200 conveys the bagged raw material 800 to the direction close to the second clamping device 302, so that the edge of the second end of the outer packaging bag is placed in the opening of the second clamp of the second clamping device 302, and then the subsequent process is performed to complete the final outer packaging removal. The outer packaging removal device provided in this embodiment can realize the complete automation of the removal of the outer packaging bag, simulate the manual operation method, and is simple and efficient, so as to further save manual labor and further improve the production efficiency.

[0035] Among them, the first mounting frame is connected with the second mounting frame, and at least one of the first mounting frame and the second mounting frame is connected with the turnover arm.

[0036] In this embodiment, the first mounting bracket and the second mounting bracket are connected, and at least one of the first mounting bracket and the second mounting bracket is connected to the flipping arm. This allows the same flipping device to drive two clamping devices, simplifying the structure of the outer packaging removal equipment. For example, there can be one flipping device, which includes a flipping drive and a flipping arm connected to either the first mounting bracket or the second mounting bracket. Alternatively, there can be one flipping device, which includes a flipping drive and two flipping arms, both connected to the flipping drive and respectively connected to the first mounting bracket and the second mounting bracket. The second mounting bracket is connected; when the flipping drive drives the flipping arm to move, the flipping arm can simultaneously drive the first mounting bracket and the second mounting bracket to move. When it is necessary to lift the first end of the outer packaging bag to make a cut, the flipping drive drives the flipping arm to move, thereby lifting the mounting bracket 310 and then lifting the first clamping device 301. After the cut is completed, the flipping device is reset. When the conveying component 200 transports the second end of the outer packaging bag to the second clamping device 302, the second clamping device 302 clamps the edge of the second end. The flipping drive then drives the flipping arm to work again to finally lift the second clamping device 302.

[0037] Optionally, in the width direction of the frame 100, a flipping device is provided on both sides of the frame 100, that is, flipping arms are connected to both sides of the first mounting frame and both sides of the second mounting frame, so that the flipping device can drive the mounting frame 310 to move smoothly.

[0038] Specifically, the first mounting bracket and the second mounting bracket can be set independently of each other. The first mounting bracket and the second mounting bracket can be connected by a connection structure (e.g., welding or threaded connection, or by means of an intermediate component); or the first mounting bracket and the second mounting bracket can be integrally formed, that is, the first mounting bracket and the second mounting bracket are a whole.

[0039] Or, such as Figure 1 As shown, the flipping device includes a first flipping device 401 and a second flipping device 402. Correspondingly, the first flipping device 401 includes a first flipping drive 4011 and a first flipping arm 4012, and the second flipping device 402 includes a second flipping drive 4021 and a second flipping arm 4022. The first mounting bracket is connected to the first flipping arm 4012, and the second mounting bracket is connected to the second flipping arm 4022.

[0040] In the initial state, the first clamp and the second clamp are both in the open state; after the bagged raw materials 800 are placed on the conveying assembly 200, the conveying assembly 200 conveys the bagged raw materials 800 to the first clamping device 301, the edge of the first end of the outer packaging bag is placed in the opening of the first clamp, the first overturning drive member 4011 in the first overturning device 401 drives the first overturning arm 4012 to rotate, and the first clamp is lifted by the first overturning arm 4012, and when the first end is lifted to a set position, the bag cutting drive member drives the cutter 503 to move to cut the outer packaging bag; then, the first overturning drive member 4011 drives the first overturning arm 4012 to move to reset, and the bagged raw materials 800 fall back to the conveying assembly 200, and the conveying assembly 200 conveys the bagged raw materials 800 to the second clamping device 302 again, so that the edge of the second end of the outer packaging bag is placed in the opening of the second clamp; the second overturning drive member 4021 works to drive the second overturning arm 4022 to rotate, and the second clamp is lifted by the second overturning arm 4022, and in the lifting process of the second end, the raw materials wrapped in the inner packaging bag are separated from the outer packaging bag. With this structure, the first overturning drive member 4011 and the second overturning drive member 4021 can work independently of each other, and are easier to control.

[0041] The first clamping device 301 and the second clamping device 302 can be arranged adjacently or with a spacing.

[0042] Optionally, the first overturning device 401 and the second overturning device 402 are arranged on both sides of the rack 100 in the width direction of the rack 100, that is, the first mounting frame is connected with the first overturning arm 4012 on both sides, and the second mounting frame is connected with the second overturning arm 4022 on both sides, so that the overturning device can drive the mounting frame 310 to move stably. Specifically, when the placement point of the bagged raw materials 800 and the second clamping device 302 are located on both sides of the first clamping device 301, the conveying assembly 200 can convey the bagged raw materials 800 in one direction; when the placement point of the bagged raw materials 800 is located between the first clamping device 301 and the second clamping device 302, if the conveying direction to the second clamping device 302 is defined as the forward direction, the conveying direction to the first clamping device 301 is the reverse direction, the conveying assembly 200 first conveys the bagged raw materials 800 to the first clamping device 301 in the reverse direction, and after the first end is cut, the conveying assembly 200 conveys the bagged raw materials 800 to the second clamping device 302 in the forward direction.

[0043] Optionally, the first clamping device 301 and the second clamping device 302 have the same structure, which is convenient for processing and installation and control, including that the first mounting frame has the same structure as the second mounting frame, and the first clamp assembly has the same structure as the second clamp assembly.

[0044] Based on the above embodiments, the first tilting arm 4012 and the second tilting arm 4022 can be rotatably connected to the frame 100 at the same position.

[0045] The clamping device can be located on one side of the conveying assembly 200, and the clamping device lifts the first end from the side of the bagged raw material 800.

[0046] like Figures 1 to 3 As shown, based on any of the above embodiments, the clamping device is further located above the conveying assembly 200; there are multiple clamping assemblies 320, which are spaced apart along a direction intersecting the conveying direction of the conveying assembly 200 (for example, the conveying direction of the conveying device can be defined as vertical, and the spacing direction of the multiple clamping assemblies 320 can be defined as horizontal, that is, the spacing direction of the clamping assemblies 320 is perpendicular to the conveying direction of the conveying device); the clamping assembly 320 also includes a base, which is connected to the mounting frame 310; the clamping drive includes a clamping drive 321, and the clamp includes a first clamping plate 322 and a second clamping plate 323. The clamping drive 321 is connected to the first clamping plate 322 to drive the first clamping plate 322 to move toward or away from the second clamping plate 323. Both the clamping drive 321 and the second clamping plate 323 are connected to the base. It is understandable that the cutting tool 503 can move laterally, thereby cutting a laterally extending opening at the first end of the outer packaging, so that the raw materials containing the inner packaging bag can be removed from the outer packaging bag in the subsequent process.

[0047] In this embodiment, when the bagged raw material 800 is placed on the conveying assembly 200, unevenness may occur. Multiple clamping assemblies 320 can clamp the edge of the outer packaging bag at multiple positions, thereby stabilizing the lifting of the end of the bagged raw material 800. The edge portion that arrives at the clamping device first can be clamped by the corresponding clamp, and the edge portion that arrives later can be clamped subsequently. When it is necessary to clamp the edge of the outer packaging bag, the clamping drive 321 drives the first clamping plate 322 to move towards the second clamping plate 323 until the edge is clamped. When it is necessary to release the edge of the outer packaging bag, the clamping drive 321 drives the first clamping plate 322 to move away from the second clamping plate 323. When the first clamping plate 322 moves away from the second clamping plate 323, the gap between them forms an opening in the clamp, and the edge of the outer packaging bag can be placed on the second clamping plate 323 (at this time, the second clamping plate 323 is located below the first clamping plate 322), waiting for the first clamping plate 322 to move towards the first clamping plate 322 to clamp the edge.

[0048] like Figures 2 to 4 As shown, based on the above embodiment, the second clamping plate 323 is further located below the first clamping plate 322. Figure 2The orientation shown is only for the convenience of illustrating the relative positions of the first clamping plate 322 and the second clamping plate 323; the clamping assembly 320 also includes a lifting plate 330 connected to the base, and the clamping drive also includes a lifting drive 324 connected to the lifting plate 330, which drives the lifting plate 330 to move up and down; the clamping drive 321 and the second clamping plate 323 are both connected to the lifting plate 330.

[0049] In this embodiment, after the first clamping plate 322 and the second clamping plate 323 clamp the edge of the outer packaging bag, the lifting drive 324 works, driving the lifting plate 330 to rise. The lifting plate 330 drives the second clamping plate 323 and the clamping drive 321 to rise. The clamping drive 321 then drives the first clamping plate 322 and the second clamping plate 323 to rise synchronously, thereby raising the end of the outer packaging bag to a certain angle in advance. This allows the outer packaging bag to be separated from the inner packaging bag in advance, which is more conducive to creating a gap between the outer packaging bag and the inner packaging bag later.

[0050] like Figure 2 As shown, based on the above embodiment, the clamp assembly 320 further includes a slide rail 350 and a slider 340 slidably disposed on the slide rail 350. The lifting plate 330 is connected to the slider 340, which enables the lifting plate 330 to move smoothly, thereby making the lifting process of the end of the bagged raw material 800 smooth.

[0051] The clamping drive component 321 can be a hydraulic cylinder, an electric telescopic rod, or a motor screw 3243 mechanism, etc. Optionally, the clamping drive component 321 can be a pneumatic cylinder.

[0054] As shown in Figure 2 On the basis of the above embodiment, further, at least one of the first clamping plate 322 and the second clamping plate 323 is provided with an anti-skid structure 370, specifically, the anti-skid structure 370 can be arranged only on the plate surface of the first clamping plate 322 facing the second clamping plate 323, or only on the plate surface of the second clamping plate 323 facing the first clamping plate 322, or the anti-skid structure 370 is arranged on the plate surface of the first clamping plate 322 facing the second clamping plate 323 and the plate surface of the second clamping plate 323 facing the first clamping plate 322, so that the clamping of the outer packaging bag is more firm.

[0055] The anti-skid structure 370 can be a protrusion (such as a columnar protrusion or a block-shaped protrusion, etc.), a groove, or a rubber layer or a silica gel layer with a relatively large friction coefficient laid on the plate surface.

[0058] In the embodiment, the working of each component is controlled by the control system 600, so that the intelligentization of the outer packaging removing device can be realized. When the first inductive switch 203 detects that the bagged raw material 800 reaches the conveying member 202, the control system 600 controls the power member 201 to work, and the power member 201 drives the conveying member 202 to move to convey the bagged raw material 800 to the first clamping device 301; during the movement of the bagged raw material 800 to the first clamping device 301, when the bagged raw material 800 enters a range that can be detected by the second inductive switch 380, the second inductive switch 380 transmits the information of the bagged raw material 800 to the control system 600, and the control system 600 controls the power member 201 to slow down, so that the conveying speed of the bagged raw material 800 is slowed down, and after the third inductive switch 390 detects the edge of the end of the outer packaging bag, the control system 600 controls the first clamping cylinder to work, so that the subsequent cutting work is completed; the movement of the bagged raw material 800 to the second clamping device 302 and the working process of the second clamping device 302 are the same as the movement of the bagged raw material 800 to the first clamping device 301 and the working process of the first clamping device 301, and details are not repeated herein. The outer packaging removing device provided in the embodiment is more intelligent and automatic.

[0059] Among them, the first inductive switch 203, the second inductive switch 380 and the third inductive switch 390 can all adopt infrared sensors or ultrasonic sensors, etc.

[0060] Specifically, in some embodiments, the second inductive switch 380 and the third inductive switch 390 can be connected with the lifting plate 330.

[0061] The power member 201 can be a motor, and the conveying member 202 can be a conveying roller set. Alternatively, the conveying member 202 is a conveying belt.

[0062] A rotating shaft 900 is provided through the frame 100 in the width direction of the conveyor belt. Bearing seats 1000 are provided at both ends of the rotating shaft 900. Each bearing seat 1000 contains a bearing. Tilting devices are provided on both sides of the frame 100. One end of the tilting arm is rotatably connected to the frame 100 through a bearing.

[0063] The overall length direction of the conveyor 202 can be defined as vertical, and the width direction of the conveyor 202 can be defined as horizontal.

[0064] like Figure 1 As shown, based on the above embodiments, the outer packaging removal equipment further includes a waste bag collection device 700, which is located at one end of the conveying component 200; the control system 600 is connected to the frame 100, and the conveying component 200, clamping device, flipping device and bag cutting device 500 are all communicatively connected to the control system 600.

[0065] In this embodiment, after the raw material containing the inner packaging bag separates from the outer packaging bag, the raw material falls onto the conveyor belt. The conveyor belt carries the raw material away from the waste bag collection device 700. When the first sensor switch 203 no longer detects the bagged raw material 800, the second clamp drive activates the second clamp to open, thereby releasing the outer packaging bag. The conveyor belt then moves in the opposite direction, transporting the outer packaging bag to the waste bag collection device 700. The entire device can then wait for the next outer packaging removal operation.

[0066] The waste bag collection device 700 may include a collection compartment with an opening at the top. The outer packaging bag can directly enter the collection compartment.
