Description

Technical Field

[0001] This utility model relates to the field of pallet assembly and production technology, specifically to a water cutting device for a pallet tube insertion machine. Background Technology

[0002] Pallets are commonly used in workshops to place workpiece blanks, which facilitates both the stacking of workpieces and the loading, unloading and transportation by forklifts, and are widely used in various factories today.

[0003] Currently, pallets are mainly divided into wooden pallets, metal pallets, and plastic pallets, each with different characteristics and used in different scenarios. Plastic pallets, due to their lightweight nature and ease of placement, are increasingly used in modern factories. However, they also have the disadvantage of relatively low strength. To overcome these limitations, some manufacturers have introduced a solution of adding steel pipes to plastic pallets to increase their strength and thus achieve higher load-bearing capacity. Specifically, a small number of steel pipes are directly inserted into the plastic pallet, which neither adds excessive weight to the pallet itself nor fails to improve its strength.

[0004] Currently, plastic pallets are generally manufactured using injection molding. As is well known, injection-molded products usually require the removal of sprue gates to avoid affecting subsequent use. For plastic pallets that require the assembly of steel pipes, after the pipes are inserted, they need to be stacked for quality inspection, labeling, and shipping. If the sprue gates are not removed in time, it can easily affect subsequent operations.

[0005] However, the current production process for plastic pallets still mainly relies on manual cutting or grinding of sprue marks. Moreover, the cutting process requires repeatedly moving the pallet, which is quite troublesome and can lead to high labor intensity for workers if done for a long time.

[0006] Therefore, this application proposes a tray inserter with a cutting nozzle device that can fully automate the removal of the water inlet from the tray. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a water inlet cutting device for a tray insertion machine, which solves the problem that the current method of manually cutting the water inlet from the tray is relatively cumbersome.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a cutting nozzle device for a tray insertion machine, comprising a conveyor line for conveying trays and a cutting mechanism disposed beside the conveyor line, wherein the cutting mechanism comprises an automatic clamp, an automatic scissors, and a drive unit for moving the automatic clamp and the automatic scissors.

[0009] Preferably, it also includes a controller, the output of which is electrically connected to the input of the conveyor line, the automatic clamp, and the scissors, respectively.

[0010] Preferably, the drive unit includes at least one of a robotic arm, a servo rail, etc.

[0011] Preferably, the conveyor line includes one of the following: a conveyor belt, a roller conveyor, etc.

[0012] Preferably, it also includes a positioning unit disposed in the conveyor line for clamping and fixing the pallet.

[0013] Preferably, the positioning unit includes an interception mechanism located at the output end of the conveyor line and a clamping mechanism located at the bottom of the conveyor line. The clamping mechanism includes two clamping rods and a drive assembly for driving the two clamping rods to move closer together and separate.

[0014] Preferably, the interception mechanism includes a baffle and a lifting cylinder for driving the baffle to extend and retract up and down on the conveyor line.

[0015] Preferably, the drive assembly includes a lead screw, a threaded sleeve on the lead screw, and a motor for driving the lead screw to rotate. The two clamping rods are respectively fixedly connected to the two threaded sleeves, and the two threaded sleeves are respectively engaged with the threads of the lead screw with positive and negative threads.

[0016] Preferably, the automatic clamp is connected to the automatic scissors, and the bottom of the automatic clamp is located above the blade of the automatic scissors.

[0017] Preferably, the automatic scissors include two L-shaped handles hinged together and a first power source capable of driving at least one of the L-shaped handles to rotate, with the blades located at opposite points on the bottom surfaces of the two L-shaped handles.

[0018] Preferably, the automatic clamp includes two clamping plates and a second power source for driving the two clamping plates to come together or separate.

[0019] Preferably, the second power source is a cylinder, and the two clamping plates are L-shaped with their bottoms facing the side of the automatic scissors.

[0020] Compared with the prior art, the present invention provides a water cutting device for a tray insertion machine, which has the following advantages:

[0021] This tray insertion machine uses a sprue cutting device to automate the entire sprue removal process without human intervention. It can also collect the cut sprues, which greatly reduces the labor intensity of workers and keeps the tray surface free of sprue residue, thus preventing it from affecting subsequent processes.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-2 The present invention provides the following technical solution: a cutting device for a tray insertion machine, including a conveyor line 1 for conveying tray A and a cutting mechanism 2 located beside the conveyor line 1. The cutting mechanism 2 includes an automatic clamp 21, an automatic scissors 22 and a drive unit 23 for moving the automatic clamp 21 and the automatic scissors 22.

[0032] As an optional implementation of this utility model, when tray A is driven by conveyor line 1 to the cutting mechanism 2, drive unit 23 drives the cutting mechanism 2 to move and cause automatic clamp 21 to clamp the sprue on the surface of tray A. Then, drive automatic shears 22 to cut off the sprue. Then, drive unit 23 drives automatic clamp 21 to move out of conveyor line 1 and drop the cut sprue into the pre-prepared collection box B. After all the sprue on tray A has been cut off, conveyor line 1 is restarted to transport tray A to the next process and bring the new tray A to the cutting mechanism 2.

[0033] Among them, conveyor line 1, automatic clamp 21, automatic shears 22, and drive unit 23 all refer to common mechanisms that can be controlled by commands. These are mature and common technical solutions in other automation fields, and will not be elaborated on here. This technical solution does not limit the specific selection. Any device that can complete the conveying of tray A, clamping the sprue, and shearing the sprue should be considered within the protection scope of this technical solution.

[0034] The above structure enables a fully automated sprue removal process without human intervention. It also allows for the collection of cut sprues, significantly reducing the labor intensity of workers and ensuring that tray A remains free of sprue residue to avoid affecting subsequent processes.

[0035] Furthermore, it also includes a controller, the output of which is electrically connected to the input of the conveyor line 1, the automatic clamp 21, the automatic scissors 22, and the drive unit 23, respectively.

[0036] As an optional implementation of this utility model, the entire sprue removal process can be completed in a fully automated manner, making the entire sprue cutting device more convenient to use.

[0037] like Figure 1 As shown, the drive unit 23 includes at least one of a robotic arm, a servo guide rail, etc.

[0038] As an optional implementation of this utility model, the drive unit 23 mainly undertakes the task of moving the automatic clamp 21 and the automatic scissors 22. However, since the injection molded parts are basically made by the mold, the position of the sprue on the tray A and the shape and size of the sprue itself are fixed. Since the operation of the conveyor line 1 is also controlled, the movement trajectory of the drive unit 23 can also be fixed under the condition that the stopping position of the tray A on the conveyor line 1 is fixed. Therefore, the robot and the servo guide can complete all the sprue cutting tasks by simple trajectory program control without the visual recognition and positioning function. Therefore, the selection of the robot and / or the servo guide can be well applied to the drive unit 23 in this technical solution. Moreover, such a design will not be too expensive and is suitable for the mass production and processing of the tray A.

[0039] like Figure 1 As shown, conveyor line 1 includes one of the following: conveyor belt, roller conveyor, etc.

[0040] As an optional implementation scheme of this utility model, in the current field of automation, both conveyor belts and roller conveyors are common and relatively mature existing technologies. It should be understood that any method that can complete the automatic conveying function can be included within the protection scope of the conveyor line 1 in this technical solution.

[0041] Preferably, conveyor line 1 is a roller conveyor consisting of multiple powered rollers 11. Although both conveyor belts and roller conveyors can be used to transport pallets A, pallets A are typically large and heavy products, so roller conveyors generally have a better load-bearing capacity and are therefore more advantageous. Conveyor belts require additional support plates, and for the subsequent installation of positioning unit 3, the clamping rod 321 can pass directly through the gap between adjacent rollers, while conveyor belts, although capable of this, have weaker adaptability to pallets A of different sizes. Therefore, using a roller conveyor consisting of multiple powered rollers 11 has a more significant advantage.

[0042] like Figure 1 and Figure 3 As shown, it also includes a positioning unit 3 located in the conveyor line 1 for clamping and fixing the pallet A.

[0043] As an optional embodiment of this utility model, during the sprue-cutting process on tray A, tray A is fixed in place by positioning unit 3 to ensure that tray A does not shift during the sprue-cutting process, thus preventing the sprue from failing to be cut off smoothly. It should be understood that the positioning unit 3 is only limited to fixing the position of tray A, and can include many existing methods for fixing products on conveyor line 1, and this technical solution does not specifically limit it.

[0044] like Figure 1 and Figure 3 As shown, the positioning unit 3 includes an interception mechanism 31 located at the output end of the conveyor line 1 and a clamping mechanism 32 located at the bottom of the conveyor line 1. The clamping mechanism 32 includes two clamping rods 321 and a drive assembly 322 for driving the two clamping rods 321 to move closer together and separate. The interception mechanism 31 includes a baffle 311 and a lifting cylinder 312 for driving the baffle 311 to extend and retract up and down on the conveyor line 1. The drive assembly 322 includes a lead screw 3221, a threaded sleeve 3222 on the lead screw 3221, and a motor 3223 for driving the lead screw 3221 to rotate. The two clamping rods 321 are respectively fixedly connected to the two threaded sleeves 3222, and the two threaded sleeves 3222 are respectively engaged with the threads of the lead screw 3221 with positive and negative threads.

[0045] As an optional implementation of this utility model, when positioning and fixing pallet A, the interception mechanism 31 intercepts pallet A at the output end of the conveyor line 1. The lifting mechanism pushes the baffle 311 out of the conveyor line 1 to intercept pallet A. Then, the driving component 322 in the clamping mechanism 32 drives the two clamping plates 211 to move closer to each other and clamp the two sides of pallet A from the bottom of the conveyor line 1, thereby achieving the positioning and fixing of pallet A.

[0046] like Figure 2As shown, the automatic clamp 21 is connected to the automatic scissors 22, and the bottom of the automatic clamp 21 is located above the blade of the automatic scissors 22. The automatic scissors 22 includes two L-shaped handles 221 that are hinged together and a first power source that can drive at least one of the L-shaped handles 221 to rotate. The blade is located at the opposite side of the bottom surface of the two L-shaped handles 221. The automatic clamp 21 includes two clamping plates 211 and a second power source 212 for driving the two clamping plates 211 to move closer or separate. The second power source 212 is a cylinder. The two clamping plates 211 are L-shaped and their bottoms face one side of the automatic scissors 22.

[0047] As an optional implementation of this utility model, when cutting off the sprue, the cylinder in the automatic clamp 21 drives the two clamping plates 211 to come together, thereby clamping the sprue to be cut off. The first power source in the automatic scissors 22 drives the handle 221 to rotate, causing the blades in the two handles 221 to come together, thereby realizing the cutting action of the sprue. Furthermore, by placing the automatic scissors 22 below the automatic clamp 21, the sprue can be completely cut off while clamping it, leaving no residue.

[0048] Since the automatic scissors 22 are already a very mature existing technology, there are actually many options for the first power source, such as telescopic rods, motors, etc. In this technical solution, any method that can drive the two blade handles 221 to move closer or further apart is within the protection scope of this technical solution.

[0049] The working principle and usage process of this utility model: When pallet A is driven by conveyor line 1 to the cutting mechanism 2, the interception mechanism 31 intercepts pallet A at the output end of conveyor line 1. The lifting mechanism pushes the baffle 311 out of conveyor line 1 to intercept pallet A. Then, the driving component 322 in the clamping mechanism 32 drives the two clamping plates 211 to move closer to each other and clamp the two sides of pallet A from the bottom of conveyor line 1, thereby achieving the positioning and fixing of pallet A. Then, the driving unit 23 drives the cutting mechanism 2 to move to the water outlet to be cut.

[0050] When the sprue is cut off, the cylinder in the automatic clamp 21 drives the two clamping plates 211 to come together, thereby clamping the sprue to be cut off. The first power source in the automatic shears 22 drives the handle 221 to rotate, causing the blades in the two handles 221 to come together, thereby realizing the cutting action of the sprue.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
