Description

Technical Field

[0001] The invention relates to the technical field of cigarette sheet glue production, and in particular to a glue sheet hanging rod device. Background Art

[0002] During the production process of tobacco sheet glue, the cut sheets need to be hung on hanging rods, and then several hanging rods are hung on the hanging rack car. After the sheets are dried for 24 to 48 hours, they are transported to the drying room for drying to complete the production of tobacco sheet glue.

[0003] CN110282428A discloses an automatic film hanging machine, which uses a hanging jaw to extract the film and move it to the hanger. The hanging jaw can pass through the hanger based on a fork-shaped structure, so as to hang the film on the hanger, completing the docking hanging of the film, thereby realizing the automatic hanging of the film. However, this method requires cutting the film strip into pieces in advance, separating the film, making two adjacent pieces of film pull a certain distance apart, and then hanging the film on the hanging rod one by one, which cannot achieve continuous hanging rods, and only one piece of film can be hung on each hanging rod. Summary of the invention

[0007] The swing-in cutting mechanism is arranged below the discharge port of the rubber strip conveyor belt and is used to cut the continuous rubber strip into films;

[0008] The hanging rod conveying mechanism is located below the swing-in cutting mechanism, and the hanging rod conveying mechanism comprises: a rod feeding station, a hanging rod station and a rod discharging station arranged in sequence along the film width direction, and the hanging rod conveying mechanism is used for step-by-step conveying of the hanging rod, so that the hanging rod passes through the rod feeding station, the hanging rod station and the rod discharging station in sequence;

[0009] The swing-in cutting mechanism is located above the hanging rod station, the rubber strip naturally falls to the outside of the hanging rod, and then the swing-in cutting mechanism cuts the rubber strip, so that the cut end of the cut film naturally falls and hangs on the hanging rod to complete a film hanging action.

[0010] Furthermore, the swing-in cutting mechanism comprises:

[0011] A swing arm assembly is provided below the discharge port of the rubber strip conveyor belt and is located on either side of the rubber strip, and is used to drive the rubber strip to swing to the other side;

[0012] The cutter is arranged at a relative position of the swing rod assembly. The swing rod assembly drives the rubber strip to swing, and the cutter cuts the rubber strip into pieces. The cut ends naturally fall on the side opposite to the side where the pieces naturally fall, and the pieces are hung on the hanging rod to complete a hanging action.

[0013] Furthermore, the swing arm assembly comprises:

[0014] Swing drive member;

[0015] The swing rod is arranged along the width direction of the rubber strip, and the swing driving member is connected to the swing rod to drive the swing rod to swing toward the rubber strip.

[0016] Further, the conveying speed of the hanging rod is matched with the time required for half the length of the film to fall to one side of the hanging rod.

[0017] Furthermore, the hanging rod conveying mechanism comprises:

[0018] Ring conveyor, the ring conveyor performs step-by-step motion;

[0019] A plurality of hanging rod support arms, the plurality of hanging rod support arms are arranged along the conveying direction of the circular conveyor, and two adjacent hanging rod support arms jointly carry a hanging rod; the hanging rod support arms extend outward from the circular conveyor so that a space for the cut end of the film to fall is formed between the hanging rod and the circular conveyor;

[0020] The hanging rod support arm moves with the circular conveyor so that the hanging rod passes through the rod entry station, the rod hanging station and the rod exit station in sequence.

[0021] Furthermore, the film hanging rod device also includes:

[0022] The rod-out mechanism is arranged at the rod-out station and is used for moving out the hanging rod that is fully hung with films at the rod-out station.

[0023] Furthermore, the rod-exiting mechanism comprises:

[0024] The rod-out driving member is arranged on the frame of the hanging rod conveying mechanism and is located at the rod-out station;

[0025] The rod-out arm is connected to the rod-out driving member, and the rod-out driving member drives the rod-out arm to move the hanging rod hung with films on the rod-out station out of the rod-out station.

[0026] Furthermore, the rod-out driving member is a hydraulic cylinder or an air cylinder, and the hydraulic cylinder or the air cylinder is located on one side of the hanging rod, driving the rod-out arm to move the hanging rod forward to make way for the rod-out station.

[0029] Working principle of the present invention:

[0030] After the sheeting, the continuous rubber strips are sent to the discharge of the conveyor belt through the conveyor belt. While the rubber strips are continuously output and dropped from the discharge end, the hanging rod conveying mechanism located on the inner side below the rubber strips conveys the hanging rods along the width of the rubber strips for a hanging film placement distance. The hanging rod conveying speed matches the time required for the required half-length of the film to fall to one side of the hanging rod. When the hanging rod is in place, the swing rod assembly and the cutter work together. The swing rod assembly swings the rubber strip toward the cutter. After the rubber strip is cut by the cutter, the cut end naturally falls and hangs symmetrically on the hanging rod to complete a hanging film action. Then the swing rod assembly quickly resets, and the hanging rod conveying mechanism moves another hanging film placement distance. The above actions are repeated to achieve the function of hanging multiple hanging films on a hanging rod at intervals.

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

[0032] (1) The film hanging rod equipment provided by the present invention realizes the continuous and automated processing of films from cutting to hanging rods.

[0033] (2) The equipment adopts the method of cutting and hanging the rods at the same time, which is different from the original method of cutting and separating the rods first and then hanging them one by one, which greatly improves the production efficiency.

[0034] (3) Multiple films can be hung on the same long hanging rod at intervals to facilitate subsequent dense storage and drying, thereby improving the space storage rate.

[0035] (4) The film hanging method in CN110282428A requires staggering the film hanging jaws and the hanger, which will result in different lengths of the film hanging on both sides, affecting the subsequent drying uniformity. In the present invention, the lengths of the film hanging on both sides of the hanging rod can be made basically the same, which can ensure the uniformity of drying and improve product consistency.

DETAILED DESCRIPTION

[0048] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0049] Example 1

[0050] like Figure 1 As shown, this embodiment discloses a system for cutting continuous rubber strips 8 into pieces and automatically hanging them on rods and racks, the system comprising a film hanging rod device and a rack system, wherein the film hanging rod device is connected to an upstream conveyor belt 1 to realize automatic cutting, automatic hanging on rods and automatic unloading of incoming materials (continuous rubber strips 8), and the rack system can put the hanging rods 9 full of films 81 on the racks for subsequent drying.

[0051] Specifically, Figure 2-3As shown, the film hanging rod device includes: a swing-in cutting mechanism 3, a hanging rod conveying mechanism and a rod discharging mechanism 3. The hanging rod conveying mechanism conveys the hanging rod 9 to the rod-in station, the hanging rod station and the rod-out station arranged in sequence along the width direction of the film 81 in a step-by-step manner. The entrance end of the rod-in station can be provided with a rod-in mechanism such as a manipulator. When the hanging rod support arm 21 of the hanging rod conveying mechanism reaches the rod-in position, the rod-in mechanism puts a hanging rod 9 on the hanging rod support arm 21 to realize the supply of the hanging rod 9. The swing-in cutting mechanism 3 is arranged below the discharge port of the rubber strip conveyor belt 1. When the rubber strip 8 falls to a specified length, the swing-in cutting mechanism 3 is activated to cut the rubber strip 8 into a film 81 of a specific length, and the film 81 is hung on the hanging rod 9 below. At this time, the hanging rod conveying mechanism is activated to convey the hanging rod 9 along the width direction of the film 81 by a hanging film placement distance, and a gap is left between two adjacent films 81 so that the subsequent rod discharging mechanism can clamp the rod. When a hanging rod 9 is fully hung with films 81 (in the present embodiment, each hanging rod 9 is hung with five films 81), the hanging rod 9 fully hung with films 81 completely enters the rod output station, at which time the rod output mechanism 3 is actuated to transfer the hanging rod 9 to the rack system, which then performs the shelving operation, thereby realizing automatic cutting, automatic hanging and automatic shelving of continuous rubber strips, greatly improving production efficiency.

[0052] Specifically, the hanging rod conveying mechanism is a circular conveyor 2 with step-by-step motion, and a number of hanging rod support arms 21 are arranged at equal intervals on its conveying chain. The hanging rod support arms 21 extend outward from the circular conveyor 2 so that a space for the cut end of the film 81 to fall is formed between the hanging rod 9 and the circular conveyor 2. The two hanging rod support arms 21 support the two ends of the hanging rod 9 respectively, and the three connected hanging rod support arms 21 support two hanging rods 9 in total. The hanging rod support arms 21 make circular motion on the vertical plane with the conveying chain, thereby realizing the recycling of the hanging rod support arms 21. At least one in-position detection sensor 35 is provided on the frame of the hanging rod conveying mechanism. When the in-position detection sensor 35 detects the hanging rod support arm 21, it means that the conveying chain has just moved the length of a hanging rod 9. At this time, the rod discharging mechanism 3 is actuated to carry out the rod discharging.

[0053] like Figure 4As shown, the swing-in cutting mechanism includes: a swing rod assembly and a cutter 43. The swing rod assembly includes a swing motor 41 and a swing rod 42. The swing motor 41 is located at the discharge port of the conveyor belt 1 and is connected to the swing rod 42 through a fixed shaft and a connecting plate. The swing rod 42 is arranged along the width direction of the rubber strip 8 and is located on the outside of the rubber strip 8. The swing motor 41 drives the swing rod 42 to swing inward, so that the rubber strip 8 moves toward the cutter 43 and is cut by the cutter 43 to cut into a film 81. The cut end of the film 81 moves to the inside of the hanging rod 9 under the action of the swing rod 42, and the film 81 hangs on the hanging rod 9 after naturally falling to complete a film hanging action. It should be noted that the conveying speed of the hanging rod 9 matches the time required for half the length of the film 81 to fall to one side of the hanging rod 9, and the distance from the cutter 43 to the axis of the hanging rod is slightly larger than half the length of the film 81. The two sides of the same film 81 are symmetrically distributed with the hanging rod 9 as the axis as much as possible, and the two sides of the hanging rod 9 are the same length, which can improve the uniformity of drying and avoid the problem of different drying degrees on the two sides of the hanging rod 9 of the same film 81.

[0054] Further, the rod-out mechanism 3 includes: a rod-out cylinder 31 and a rod-out arm 32, the rod-out cylinder 31 and the rod-out arm 32 are located inside the hanging rod 9, the rod-out arm 32 is connected to the output end of the rod-out cylinder 31, and a clamping arm 34 is arranged on the rod-out arm 32, and the clamping arm 34 is driven by the clamping cylinder 33 to clamp the hanging rod 9. Specifically, when the in-place detection sensor 35 detects the hanging rod support arm 21, the rod-out cylinder 31 is actuated for the first time, driving the rod-out arm 32 to move forward slightly, so that the clamping arm 34 partially extends to the interval between the two films 81, and then the clamping cylinder 33 is actuated to drive the clamping arm 34 to clamp the hanging rod 9, and then the rod-out cylinder 31 is actuated for the second time, moving the hanging rod 9 forward and sending it into the hanging rod sorting mechanism 5 to wait for the hanger, and the rod-out mechanism 3 is reset after releasing the hanging rod 9, waiting for the next rod-out operation.

[0055] like Figure 5 As shown, the hanger system includes: a hanger 7, a hanger rod arrangement mechanism 5 and a rod shifting mechanism 6. The hanger 7 is a C-shaped structure with one end open. It is provided with several layers. On each layer, several second brackets 71 are arranged at equal intervals. Two opposite second brackets 71 respectively support the two ends of the hanger rod 9. The hanger rod arrangement mechanism 5 is located at the open end of the hanger 7. It is composed of a chain conveyor 51 and several first brackets 52 arranged thereon. Two opposite first brackets 52 respectively support the two ends of the hanger rod 9. The inlet end of the chain conveyor 51 is directly opposite to the discharge station of the film hanger rod equipment. The rod discharging mechanism 3 moves the hanger rod 9 forward and places it on the first group of first brackets 52 at the inlet end of the chain conveyor 51. Then, the chain conveyor 51 moves once to move the hanger rod 9 toward the hanger 7 by one position. The chain conveyor 51 performs cyclic stepping motion with equal intervals. By using the first brackets 52 with equal intervals, the hanger rod 9 can be evenly arranged so that the subsequent rod shifting mechanism 6 can grab and put it on the shelf.

[0056] Furthermore, if Figure 7-9As shown, the rod shifting mechanism 6 includes: a gantry 61 and a grabbing manipulator 62. The grabbing manipulator 62 is mounted on the gantry 61 through a lateral movement unit 64 and a lifting unit 65. The lateral movement unit 64 is used to realize the lateral movement of the grabbing manipulator 62 from the discharge end of the chain conveyor 51 to the corresponding position of the hanger 7, and the lifting unit 65 is used to realize the lifting and lowering of the grabbing manipulator 62. The grabbing manipulator 62 is provided with a plurality of through holes larger than the diameter of the end of the hanging rod 9 on the clamping plate 63 driven by a hydraulic cylinder. The hydraulic cylinder drives the two clamping plates 63 to approach each other, and the hanging rod 9 is inserted into the corresponding through hole, so that multiple hanging rods 9 can be moved simultaneously.

[0057] Example 2

[0058] like Figure 2 As shown, in this embodiment, the hanger 7 is stacked by several layers of plug-in pallets 72, and each layer of plug-in pallets 72 is provided with several second supporting arms 71. After each layer of hanging rods 9 is put on the shelf, another layer of plug-in pallets 72 is stacked on top. The height of the hanger 7 can be adjusted according to actual conditions.

[0059] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not used to limit the present invention. For those skilled in the art to which the present invention belongs, some simple deductions, modifications or substitutions can be made according to the idea of ​​the present invention.
