Description

Technical Field

[0001] The invention relates to the technical field of apple packaging, in particular to a net cover device of a net cover cartoning machine. Background Art

[0002] In order to realize the automatic packaging of apples, the first basic function that needs to be done is to expand the foaming net. Only after the net is expanded can the subsequent work such as fruit netting, labeling, and packing be carried out to achieve the purpose of automatic packaging of apples. However, in traditional apple packaging operations, the netting link is basically completed manually, and the corresponding netting work is also done manually. There is no automatic netting equipment on the market. Manual netting has problems such as low efficiency, high cost, and failure to meet market demand. The emergence of netting devices can solve this problem. By cooperating with other devices such as netting support to automatically net apples, the dilemma of no automatic equipment in the netting link of the current apple packaging industry can be solved.

[0003] The main working principle of the device currently used for putting apples on the net cover is to use a needle plate to poke the net open, then put the net on the net support device, and use the net support device to stretch the net, and then put the apples therein. For example, the Chinese patent with announcement number CN108327967A adopts this kind of scheme to stretch the net, but this kind of scheme also has certain problems. The needle plate piercing the net has high requirements on the posture of the net. When the net rolls down from the net plate, it sometimes bends. At this time, the needle plate is easy to pierce the net and thus cannot pierce the net. In addition, after the net is put on the net support device, the needle plate will stick to the net when it is separated from the net, and the net cannot be separated from the needle plate, so that the net is brought out by the needle plate.

[0004] In view of the above problems, there is an urgent need for a convenient, fast and effective device for opening the foaming net to effectively pave the way for realizing the automated packaging of apples. Summary of the invention

[0005] In order to solve the above problems, the present invention proposes a net cover device for a net cover box loading machine.

[0006] The technical solution adopted by the present invention is: a net cover device of a net cover box machine, comprising:

[0007] Base;

[0008] A rubbing device, disposed on the base and configured to rub the net sleeve open;

[0009] A conveying device, disposed at one end of the base, configured to convey the net sleeve to the rubbing device for rubbing; and a clamping device,

[0010] The mesh sleeve is arranged at the other end of the base and is configured to convey the mesh sleeve opened by the opening device to the mesh sleeve box-packing machine.

[0011] Through the above technical solution, the rubbing method is adopted, which can effectively utilize the characteristics of the foaming net and use friction to rub the net sleeve open, so as to realize the shape of the net sleeve from a flat closed state to an irregular elliptical open state, and then conveniently, quickly and effectively open the net sleeve and transport it to the net sleeve supporting device, which paves the way for realizing the automated packaging of apples.

[0012] Furthermore, the rubbing-opening device comprises a conveyor belt and a baffle plate which are arranged in parallel along the length direction of the base, and a mesh sleeve rubbing-opening conveying channel is provided between the conveyor belt and the baffle plate.

[0013] The above-mentioned arrangement enables the mesh sleeve to be conveyed while the mesh sleeve is being rubbed, and uninterrupted rubbing work can be achieved, thereby effectively improving the processing efficiency.

[0014] Furthermore, the baffle can be adjusted in distance relative to the conveyor belt.

[0015] Through the adjustable design of the baffle in the above technical solution, the width of the conveying channel can be changed to adapt to different types of mesh sleeves, thereby improving the application range of the equipment.

[0016] Furthermore, the conveyor belt includes two rollers rotatably arranged on a base, and a belt body sleeved on the two rollers, and a limiting device for internal pressure limiting is arranged inside the belt body near the baffle side on the base.

[0017] By setting a limit device for internal pressure limiting in the belt body near the baffle side in the above technical solution, the belt body can be effectively prevented from being concave due to being squeezed by the mesh sleeve, and the situation in which the mesh sleeve cannot be rubbed open due to reduced friction can be avoided.

[0018] Furthermore, the conveying device comprises:

[0019] Frame;

[0020] A conveying roller group is arranged on the top of the frame;

[0021] A cutting roller group is arranged on the frame and is located below the conveying roller group;

[0022] and a material pushing mechanism, which is arranged on the side of the frame away from the base and below the cutting roller group;

[0023] The base is connected to the frame and extends below the cutting roller group.

[0024] By adopting the double-roll rolling method for feeding and cutting in the above technical solution, not only continuous operation can be achieved, but also the efficiency is very high.

[0025] Furthermore, the clamping device includes a rotating arm arranged on the base, and a clamping claw arranged at one end of the rotating arm.

[0026] Furthermore, the pushing mechanism includes a pushing claw and a driving mechanism for driving the pushing claw to reciprocate along the longitudinal side of the base.

[0027] Furthermore, the end of the baffle close to the conveying device is bent toward the side away from the conveyor belt to form a flared opening.

[0028] By adopting the above technical solution and setting the expansion structure, the mesh sleeve can enter the mesh sleeve rubbing and conveying channel more smoothly.

[0029] Furthermore, a sensor for detecting the net sleeve is arranged on the base near the clamping device end.

[0030] By providing a sensor for detecting the position of the net sleeve through the above technical solution, the clamping device can transport the net sleeve more promptly.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] The invention utilizes friction conveying to open the mouth of the mesh sleeve during the conveying process, which is very convenient, quick and effective; a simple method and principle are adopted to realize the rubbing open of the foaming mesh sleeve, and the method can be adjusted according to mesh sleeves of different models to ensure that most of the mesh sleeves can be rubbed open; and there is no phenomenon of deviation or jamming of the mesh sleeve, and the invention is more in line with the design of automated assembly lines, and has higher work efficiency; it can also reduce manpower, reduce product production costs, and greatly improve labor productivity.

[0043] In order to realize the automatic netting of apples, the first basic function that needs to be done is to open the foam net. Only after the net is opened can the subsequent work such as netting, labeling, and packing of fruits be carried out to achieve the purpose of automatic packaging of apples. The existing way to open the foam net is to use a needle plate to poke the net open. The needle plate has high requirements on the posture of the net. When the net rolls down from the net plate, it sometimes bends. At this time, the needle plate is easy to pierce the net and cannot pierce the net. In addition, after the net is put on the net supporting device, the needle plate will stick to the net when it is separated from the net, and the net cannot be separated from the needle plate, so the net is taken out by the needle plate.

[0044] Through experiments, it is found that when the foaming mesh sleeve is rubbed with a smooth material, the friction force is relatively large. The mesh sleeve can be rubbed open by clamping the mesh sleeve with a smooth material to open a certain opening, and then the protruding end of the mesh sleeve is clamped by a clamping device and conveyed to the mesh sleeve supporting device. In this way, the mesh sleeve opening and mesh sleeve operation can be completed quickly and effectively; therefore, the present invention provides a mesh sleeve device for a mesh casing machine, referring to Figure 1-Figure 5 The net cover device of the net cover packing machine includes a base 1, a rubbing device, a conveying device and a clamping device: the rubbing device is arranged on the base 1 for rubbing the net cover; the conveying device is arranged at one end of the base 1 for conveying the net cover to the rubbing device for rubbing; the clamping device is arranged at the other end of the base 1 for conveying the net cover after being rubbed by the rubbing device to the net cover packing machine. In this embodiment, the rubbing device is arranged to rub the net cover, which can effectively use the characteristics of the foaming net and rub the net cover by friction, so as to realize the shape of the net cover from a flat closed state to an irregular elliptical open state, and then conveniently, quickly and effectively open the net cover and convey it to the net cover supporting device, which paves the way for realizing the automatic packaging of apples.

[0045] Specifically, the rubbing device includes a conveyor belt 2 and a baffle 3 arranged in parallel along the length of the base 1, and a mesh sleeve rubbing and conveying channel 4 is between the conveyor belt 2 and the baffle 3; the width of the conveying channel 4 is smaller than the thickness of the mesh sleeve, and its height is lower than the height of the mesh sleeve. The mesh sleeve enters from the input end of the conveying channel 4, and is conveyed along the conveying channel 4 under the drive of the conveyor belt 2. The width of the conveying channel 4 is smaller than the thickness of the mesh sleeve. During the conveying process, the two layers of the mesh sleeve can rub against each other, thereby opening an opening at the upper end of the mesh sleeve, so that the mesh sleeve can be conveyed while rubbing the mesh sleeve, thereby realizing uninterrupted rubbing work and effectively improving the processing efficiency.

[0046] More specifically, when the mesh sleeve is just cut, it is a double-layered structure, and the center distance between the two semicircles of the mesh sleeve is n. When it is frictionally transported in the transport channel to a distance of 1 / 2n, the upper end of the mesh sleeve forms an irregular elliptical opening state, so the length of the transport channel is greater than 1 / 2n. In some embodiments, in order to better clamp the mesh sleeve, the length of the transport channel is set to an integer multiple of 1 / 2n.

[0047] It is worth noting that the baffle 3 can be adjusted relative to the conveyor belt 2; the adjustable design is adopted, so that the width of the conveying channel 4 can be changed to adapt to different types of mesh sleeves, thereby improving the application range of the device; specifically, the base 1 is provided with two adjustment grooves 5, and the adjustment grooves 5 are arranged in the vertical direction of the long direction of the conveyor belt 2. Fixed studs that can pass through the adjustment grooves 5 are arranged at the bottom of the baffle 3 and the corresponding positions of the two adjustment grooves 5. A nut for fixing it to the base 1 is screwed on the end of the fixed stud located below the base 1.

[0048] In this embodiment, the conveyor belt 2 includes two rollers that can be rotatably arranged on a base, and a belt body mounted on the two rollers; the roller includes a belt shaft portion and a mounting shaft portion, the belt shaft portion and the mounting shaft portion are an integral structure with a unified axis, the roller is vertically and rotatably inserted into the mounting shaft hole of the base 1 through the mounting shaft, and the belt body is mounted on the belt shaft portions of the two rollers. In actual application, one of the rollers is connected to a driving mechanism for driving it to rotate, and the driving mechanism can be a motor, which drives the conveyor belt 2 to rotate through the driving mechanism, thereby realizing the friction conveying operation of the mesh sleeve.

[0049] It should also be noted that in order to prevent the belt body from being unable to provide sufficient friction due to the internal pressure of the mesh sleeve when frictionally conveying the mesh sleeve, a limiting device 6 for internal pressure limiting is provided on the inner side of the belt body near the baffle side on the base 1; by providing the limiting device 6 for internal pressure limiting, the belt body can be effectively prevented from being concave due to the squeezing of the mesh sleeve, and the situation that the mesh sleeve cannot be rubbed open due to the reduction of friction is avoided. Specifically, the limiting device 6 is a plurality of limiting columns arranged between the two sides of the belt body, and the plurality of limiting columns are arranged equidistantly along the length of the belt body. The limiting columns can be fixedly mounted on the base 1 or rotatably mounted on the base 1. This embodiment is fixedly mounted with the base 1. In some other embodiments, the limiting device 6 can be a limiting plate arranged along the length of the belt body, and the limiting plate is fixed on the base 1 and is located at the inner side of the belt body near the baffle 3.

[0050] In this embodiment, the conveying device can continuously provide mesh sleeve feeding operations, specifically including a frame 7, a conveying roller group 8, a cutting roller group 9 and a pushing mechanism; the conveying roller group 8 is arranged on the top of the frame 7; the cutting roller group 9 is arranged on the frame 7 and is located below the conveying roller group 8; the pushing mechanism is arranged on the side of the frame 7 away from the base 1 and is located below the cutting roller group 9; the base 1 is connected to the frame 7 and extends to below the cutting roller group 9. By adopting a double-roll rolling method for feeding and cutting, not only can continuous operation be achieved, but also the efficiency is very high.

[0051] In this embodiment, the conveying roller group 8 is composed of two rollers relatively mounted on the frame 7 in a rollable manner, and the outer circumferential surface of the rollers is smooth. In actual application, one or both of the rollers are connected to a driving motor for driving the rollers to rotate. There is a material conveying passage between the two rollers, and the mesh passes through the material conveying passage, and the material is conveyed by the rotation of the rollers. In some other embodiments, the outer circumferential surface of the rollers may be provided with convex ribs or other structures that can play a friction role, so as to better convey the mesh.

[0052] In this embodiment, the cutting roller group 9 includes two cutting rollers 91 which can be relatively and rotatably mounted on the frame 7. A cutting knife 92 is provided on the outer circumferential surface of the two cutting rollers 91 along its axial direction. When the cutting knives 92 on the two cutting rollers 91 roll to a relative position, an incision for cutting the mesh sleeve can be formed. After the two cutting rollers 91 roll to separate the two cutting knives 92 from each other, a cutting passage is provided between the two cutting rollers 91 for allowing the mesh sleeve to pass. The outer ends of the shaft ends of the two cutting rollers 91 extending out of the shaft holes of the frame are provided with meshing gears. The two gears mesh with each other to ensure that the two cutting rollers 91 rotate synchronously. In actual application, one of the cutting rollers is connected to a driving motor for driving it to rotate. Through the rotation of the two cutting rollers 91, the cutting passage can continuously pass through the mesh sleeve and continuously cut off the mesh sleeve.

[0053] In this embodiment, the pushing mechanism includes a pushing claw 10 and a driving mechanism 11 for driving the pushing claw 10 to reciprocate along the long side of the base. The pushing mechanism is arranged below the cutting roller group 9 on the frame 7, and the driving mechanism 11 is located on the side of the frame 7. The pushing claw 10 is located directly below the cutting roller group 9 and can reciprocate along the mouth of the conveying channel 4 under the drive of the driving mechanism 11, thereby pushing the mesh sleeve cut off by the cutting roller group 9 to the mouth of the conveying channel 4. The driving mechanism 11 in this embodiment is a cylinder.

[0054] In this embodiment, the clamping device includes a rotating arm 12 arranged on the base 1, and a clamping claw 13 arranged at one end of the rotating arm 12; specifically, a fixed seat is fixed to the end of the base 1 away from the conveying device, and the rotating arm 12 is rotatably connected to the fixed seat. When it is rotated to the side of the rubbing device, the clamping claw is just located above the conveying channel 4 to clamp the net sleeve, and when it is rotated to the other side, the clamping claw is just located above the net supporting device to convey the net sleeve to the net supporting device; the clamping claw 13 of this embodiment is composed of two semicircular sleeves rotatably mounted on the rotating arm 12, and the semicircular sleeves relatively form a clamping space. The two semicircular sleeves are opened to open the clamping space The space allows the net to enter the clamping space better, the two semicircular sleeves are closed to reduce the clamping space, and the net is clamped in the clamping space by the two semicircular sleeves. In order to make the two semicircular sleeves open and close synchronously, a mutually meshing gear is installed at one end of the rotating shaft of the two semicircular sleeves to make them rotate synchronously. Before clamping the net, the two semicircular sleeves are opened to expand the clamping space, and then the rotating arm 3 is rotated to rotate the clamping claw 3 to the top of the conveying channel. At this time, the net is just located in the clamping space, and then the two semicircular sleeves are closed to reduce the clamping space to clamp the net, and then the rotating arm is rotated to transport the net to the net support device to perform the apple netting work. In actual application, the rotating arm 12 has a driving mechanism that drives it to rotate, and the semicircular sleeve drives the driving device that drives it to rotate to realize opening and closing.

[0055] Based on the above embodiment, the end of the baffle 3 close to the conveying device is bent toward the side away from the conveyor belt to form a flared opening; the flared opening structure can make the mesh sleeve enter the mesh sleeve rubbing conveying channel more smoothly.

[0056] Furthermore, a sensor 14 is provided on the base 1 near the clamping device end. The sensor 14 is used to detect whether the mesh is delivered to the right place. In specific applications, it can be connected to a programmable controller together with the driving mechanism of the rotating arm 12. When it detects that the mesh is in place, it can send a signal to the controller, so that the clamping device can deliver the mesh more timely, thereby improving efficiency.

[0057] In some embodiments, the sensor 14 is adjustably mounted on the base 1. Specifically, a mounting groove 15 is installed on the base 1 along the conveying channel 4, and the sensor 13 is inserted into the mounting groove 15, so that its position in the mounting groove can be adjusted according to actual application requirements.

[0058] The mesh opening process of the present embodiment is as follows: the mesh is first input from the conveying roller group 8, and under the action of the conveying roller group 8, the mesh is conveyed to the cutting roller group 9, the cutting roller group 9 cuts the mesh, and the cut mesh falls on the base 1, and then the mesh is pushed into the mouth of the conveying channel 4 by the pushing claw 10, and under the action of the rotation of the conveyor belt 2, the mesh is conveyed along the conveying channel 4, and the mouth of the mesh is rubbed open at the same time, and when it is conveyed to the end, the clamping device clamps the rubbed mesh onto the mesh opening device to perform the apple netting operation; in specific applications, the driving structures and sensors of each mechanism in the netting device can be connected to a programmable controller, and are uniformly controlled by the controller.

[0059] It should be noted that the device of this embodiment can also be applied to the net-laying operation during the packaging of other fruits.
