Description

Technical Field

[0001] This utility model relates to the field of packaging equipment, specifically to a directional and tilting conveyor for packaging equipment. Background Technology

[0002] Currently, conveyors are widely used in packaging equipment to automate the flow of packaged products.

[0003] The online turning device for bulk packaging disclosed in CN221234658U, through the setting of a turning mechanism and a tilting mechanism, allows the packaging bag to rotate 90° under the tension of the turning rod after contacting the turning rod under the action of the conveying device. After the packaging bag leaves the working area of ​​the turning rod, the turning rod returns to its original position under the action of the return spring. The turned packaging bag is then conveyed to the roller, where it is tilted down, realizing the automatic turning and flattening of the packaging bag. Although the above device can complete the turning and flattening of the packaged products, there are still obvious defects in practical applications. When conveying fragile packaged products containing fragile materials or items, the packaging bag may tip over and directly impact the conveying device during the tilting process, which can easily cause the contents to break due to impact or the outer packaging to be damaged, affecting the overall quality and factory qualification rate of the packaged products. Therefore, we propose a turning and tilting conveyor for packaging equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a directional and tilting conveyor for packaging equipment, which solves the technical problem that existing conveyors, when dealing with fragile or easily damaged packaged products containing fragile materials or items, will tip over and directly impact the conveying device during the tilting process, which can easily cause the contents to break or the outer packaging to be damaged due to the impact, thus affecting the overall quality and factory qualification rate of the packaged products.

[0005] This utility model achieves the above objectives through the following technical solutions: A turning and tilting conveyor for packaging equipment includes a conveying device, on which a turning mechanism and a tilting mechanism are sequentially arranged along its conveying direction, and a protective mechanism is provided on the conveying device between the turning mechanism and the tilting mechanism. The protective mechanism includes a movable seat on the conveying device, a mounting seat rotatably mounted on the movable seat via a rotating shaft, a guide rod located inside the mounting seat, and a buffer roller body with one end movably sleeved on the outer wall of the guide rod. A buffer spring is provided between the guide rod and the buffer roller body. A rotating device for driving the rotating shaft to rotate is provided on the movable seat.

[0006] A further improvement is that the tilting mechanism includes vertical supports symmetrically arranged on both sides of the conveying device, sliders slidably arranged in the vertical supports, and tilting rollers rotatably connected to the two sliders and used to tilt the packaged products.

[0007] A further improvement is that a number of sets of locking holes 1 are provided on one side wall of the vertical support from top to bottom, and a locking hole 2 is provided on the side of the slider facing the locking hole 1. A locking pin for inserting into the locking hole 1 and the locking hole 2 is provided on one side wall of the vertical support.

[0008] A further improvement is that the vertical support has a vertical opening on the side facing the steering mechanism, and a mounting block connected to the slider is movably installed in the vertical opening. The mounting block is equipped with a second detection sensor for detecting packaged products. The second detection sensor is electrically connected to a controller, and the controller is electrically connected to the rotating device.

[0009] A further improvement is that the buffer roller body includes an elastic roller body, and both ends of the elastic roller body are connected to connecting seats. One connecting seat is movably sleeved on the outer wall of the guide rod, and an adjusting screw is threaded into the other connecting seat. An elastic buffer rod is provided at the bottom end of the adjusting screw, and a ball is embedded at the bottom end of the elastic buffer rod.

[0010] A further improvement is that a sliding block is provided below the movable seat, and the sliding block is slidably disposed in a horizontally opened groove on the conveying device. A telescopic device one is provided on one inner wall of the groove, and the output end of the telescopic device one is connected to the sliding block. A telescopic device two is embedded on the sliding block, and the output end of the telescopic device two is connected to the movable seat.

[0011] A further improvement is that a detection sensor is provided on one side of the inner wall of the mounting base for detecting the position of the connecting base. The detection sensor is electrically connected to the controller, and the detection sensor is used to cause the controller to control the rotating device to work when it detects that the connecting base has moved to a preset position.

[0012] The beneficial effects of this utility model are as follows: This invention provides a protective mechanism on the conveying device between the steering mechanism and the tipping mechanism. The buffer roller in the protective mechanism can actively support one end of the packaged product during the tipping process and effectively absorb the impact energy generated during the tipping through the buffer spring, so that the packaged product falls slowly and steadily onto the conveying device. This reduces the risk of damage to fragile packaged products caused by tipping and impact, ensures the overall quality of the packaged products, and improves the factory qualification rate of the packaged products.

Detailed Implementation

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1

[0017] Please see the appendix Figure 1-2 A turning and tilting conveyor for packaging equipment includes a conveying device 100. In this embodiment, the conveying device 100 is a conveyor belt conveyor or roller conveyor that is widely used in the art. A steering mechanism 200 and a tilting mechanism 300 are sequentially arranged on the conveying device 100 along its conveying direction (i.e., from left to right). The steering mechanism 200 in this embodiment is a conventional structure in the art. Optionally, the steering mechanism 200 in this embodiment includes a backing plate, a steering rod, a limiting post, a fixed seat, and a return spring, etc., which will not be described in detail here. When the packaged product contacts the steering rod under the action of the conveying device 100, it rotates 90° under the stretching action of the steering rod. After the packaged product leaves the working area of ​​the steering rod, the steering rod rebounds under the action of the return spring and returns to its original position through the limiting post, completing one operation. In this way, the packaged product completes the turning. A protective mechanism 400 is provided on the conveying device 100 between the steering mechanism 200 and the tilting mechanism 300. It should be noted that in this embodiment, the steering mechanism 200, the folding mechanism 300, and the protective mechanism 400 are all connected to the frame in the conveying device 100. The protective mechanism 400 includes a movable seat 402 mounted on the conveying device 100, a U-shaped mounting seat 403 mounted on the movable seat 402 and rotatable via a rotating shaft, a guide rod located within the mounting seat 403, and a buffer roller body with one end movably sleeved on the outer wall of the guide rod. A buffer spring 405 is provided between the guide rod and the buffer roller body. The movable seat 402 is equipped with a rotating device 409 that drives the rotating shaft to rotate. In this embodiment, the rotating device 409 consists of a servo motor and a reducer. The output end of the rotating device 409 and the rotating shaft are connected by a gear set (two sets of meshing gears). When the packaged product is conveyed by the conveying device 100 to the point where it is about to contact the tilting mechanism 300, the rotating device 409 is activated, driving the rotating shaft to rotate the mounting seat 403 and the buffer roller body. The product is positioned parallel to the tilting roller 301, so that it is between the tilting roller 301 and the buffer roller body at the moment of tilting. After the product is tilted by the tilting mechanism 300, one end of the product is pressed against the buffer roller body. While bearing the weight of the product, the buffer roller body moves downward to compress the buffer spring 405. This elastic buffer stroke effectively shortens the drop between the end of the product and the conveying device 100, achieving flexible absorption of the tilting impact and reducing the probability of damage to the product due to the impact of the product contacting the conveying device 100. Then, the rotating device 409 drives the mounting base 403 to reset, so that the product falls smoothly and completely onto the conveying device 100, ensuring the conveying quality and safety of the product, especially the fragile product.

[0018] Please see the appendix Figure 1-3 Preferably, the buffer roller body of this embodiment includes an elastic roller body 406. In this embodiment, the elastic roller body 406 can be a rubber roller body. Both ends of the elastic roller body 406 are connected to connecting seats 404. One connecting seat 404 is movably sleeved on the outer wall of the guide rod, and the other connecting seat 404 is threaded with an adjusting screw 407. The bottom end of the adjusting screw 407 is provided with an elastic buffer rod 408. In this embodiment, a spring telescopic rod with a built-in return spring can be used. The bottom end of the elastic buffer rod 408 is embedded with a ball. When the rotating device 409 drives the entire buffer roller body to a preparatory working position parallel to the folding roller 301, the end of the buffer roller body away from the guide rod is not suspended in the air, but is stably abutted against the other side of the frame of the conveying device 100 through the adjusting screw 407, the elastic buffer rod 408 and the ball at its bottom, thereby improving the elastic buffering performance of the buffer roller body. The position of the elastic buffer rod 408 can be finely adjusted by adjusting the screw 407, thereby enhancing the stability of the entire protective mechanism 400 during protection.

[0019] Preferably, in this embodiment, a sliding block 401 is provided below the movable seat 402. The sliding block 401 is slidably disposed in a horizontally opened groove on the conveying device 100. A telescopic device 410 is provided on the inner wall of one side of the groove. The output end of the telescopic device 410 is connected to the sliding block 401. A telescopic device 2 (not shown in the figure) is embedded on the sliding block 401. The output end of the telescopic device 2 is connected to the movable seat 402. In this embodiment, both the telescopic device 410 and the telescopic device 2 can be electric telescopic rods. The position and height of the buffer roller body can be conveniently and flexibly adjusted by the telescopic device 410 and the telescopic device 2.

[0020] Preferably, in this embodiment, the inner wall of one side of the mounting base 403 is provided with a detection sensor 411 for detecting the position of the connecting base 404. The detection sensor 411 is electrically connected to the controller. The detection sensor 411 is used to cause the controller to control the rotating device 409 to work when it detects that the connecting base 404 has moved to a preset position. In this embodiment, the detection sensor 411 can be a laser rangefinder sensor, but it is not limited to this type. When the buffer roller body bears the weight of the packaged product during the laying process, the connecting base 404 will slide down along the guide rod and compress the buffer spring 405. At this time, the detection sensor 411 continuously detects the displacement of the connecting base 404. Once it moves to the preset limit position (indicating that the packaged product has been sufficiently buffered and is about to contact the conveying device 100), the detection sensor 411 immediately sends a trigger signal to the controller. The controller then instructs the rotating device 409 to drive the mounting base 403 to rotate and reset, so that the packaged product falls smoothly and completely on the surface of the conveying device 100.

[0021] Example 2

[0022] Please see the appendix Figure 1-2 Based on Embodiment 1, the tilting mechanism 300 of this embodiment includes vertical supports 302 symmetrically arranged on both sides of the conveying device 100, sliders 303 slidably arranged in the vertical supports 302, and tilting rollers 301 rotatably connected to the two sliders 303 and used to tilt the packaged products. The vertical supports 302 of this embodiment have a vertical opening for the sliders 303 to slide. When the packaged products are conveyed to the tilting rollers 301, the packaged products are tilted down by the tilting rollers 301 and continue to be conveyed. It should be noted that the lengths of the reclining roller 301 and the elastic roller 406 are adapted to the width of the conveying device 100; Preferably, in this embodiment, a number of sets of first-type locking holes are provided on one side wall of the vertical support 302 from top to bottom, and a second-type locking hole is provided on the side of the slider 303 facing the first-type locking hole. A locking pin 304 for inserting into the first-type locking hole and the second-type locking hole is provided on one side wall of the vertical support 302, so as to facilitate adjusting the position of the slider 303 according to the packaged product, thereby changing the working height of the tilting roller 301.

[0023] Preferably, in this embodiment, the vertical support 302 has a vertical opening on the side facing the steering mechanism 200, and a mounting block connected to the slider 303 is movably installed in the vertical opening. The mounting block is equipped with a detection sensor 500 for detecting the packaged product. The detection sensor 500 is electrically connected to the controller, and the controller is electrically connected to the rotating device 409. In this embodiment, an infrared transmitter and an infrared receiver are preferably used as the detection sensor 500, and they are symmetrically installed on the corresponding mounting blocks on both sides. When the packaged product is conveyed by the conveying device 100 to the point where it is about to contact the tilting mechanism 300, it will accurately enter the detection area between the infrared transmitter and the infrared receiver, blocking the transmission path of the infrared beam. Then, the detection sensor 500 sends a signal to the controller, and the controller then starts the rotating device 409 according to the preset program, so that the protective mechanism 400 simultaneously enters the preparatory working state (that is, drives the rotating shaft to rotate the mounting base 403 and the buffer roller body to the preparatory position parallel to the tilting roller 301).

[0024] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
