Description

Technical Field

[0001] The invention relates to the field of profile production equipment, in particular to a high-efficiency cushioning machine. Background Art

[0002] In order to facilitate the storage and transportation of profiles, the factory needs to cut the profiles into finished profiles of a certain length, and stack multiple finished profiles in layers. However, in order to avoid scratching between the upper and lower layered finished profiles, the factory generally uses pads to separate them up and down.

[0003] In the prior art, the pads are mainly placed on the claws of the conveyor belt manually, with the distance between two adjacent claws being the same, and then the robot places the pads on the claws on the finished profile. Since at least three pads need to be placed on each layer of finished profile, and each transport rack generally has more than ten layers of finished profile, the amount of pads used is huge, and manual placement of pads is time-consuming and laborious. Therefore, there is an urgent need for a device that can replace manual operation. Summary of the invention

DETAILED DESCRIPTION

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0028] like Figure 1 and Figure 2As shown, the efficient pad separating machine according to the first embodiment of the invention comprises a base 100, a conveying device and two synchronously lifting devices 200, the conveying device is installed on the base 100, the two lifting devices 200 are respectively installed on the left and right sides of the conveying device, the two lifting devices 200 are provided with a plurality of material racks 300 arranged in upper and lower layers, the height of each layer of material racks 300 is consistent, all material racks 300 are parallel to the conveying direction of the conveying device, the two material racks 300 on the same layer are on the same horizontal plane, so that a plurality of pad strips can be placed on the two material racks 300 on each layer, and at the same time, it should be ensured as much as possible that the setting direction of all pad strips is orthogonal to the conveying direction of the conveying device; in order to enable the pad strips to be lowered from every two material racks 300 to the conveying device, the lifting path of each material rack 300 intersects with the upper surface of the conveying device, once the two material racks 300 on the same layer are lowered to slightly below the upper surface of the conveying device, all the pad strips of the layer are supported by the conveying device and conveyed forward.

[0029] Specifically, the lifting device 200 includes but is not limited to a gear rack lifting device, a screw nut lifting device, a cylinder lifting device or an oil cylinder lifting device. The present invention does not limit the specific structure of the lifting device 200, but for the convenience of description, the two lifting devices 200 created by the present invention are both selected as gear rack lifting devices. Each of the gear rack lifting devices includes a mounting plate 210 and a lifting motor 220, the lifting motor 220 is mounted on the outer side of the mounting plate 210, and two vertically arranged racks 230 are slidably connected to the outer side of the mounting plate 210 through a slide rail pair, and the two racks 230 are commonly connected to a plurality of material racks 300, all of which are located on the inner side of the mounting plate 210, and each of the material racks 300 is L-shaped and opens inward; the lifting motor 220 is transmission-connected to a rotating shaft 240, and the rotating shaft 240 is mounted on the outer side of the mounting plate 210 through two bearings 250, and gears 241 are respectively provided at both ends of the rotating shaft 240, and the two gears 241 are respectively meshed with the two racks 230, so that when the lifting motor 220 drives the rotating shaft 240 to rotate, the two racks 230 rise or fall at the same time, thereby driving a plurality of the material racks 300 to rise or fall. It should be noted that, since the two lifting devices 200 need to maintain a synchronous lifting state, the two lifting motors 220 are electrically connected to the same driver, and the driver drives the two lifting motors 220 at the same time.

[0030] In actual application, the length of the pad is not constant, and different specifications of finished profiles correspond to pads of different lengths. In order to make the invention adapt to pads of different lengths, two left and right moving devices are installed on the base 100, and the two left and right moving devices are respectively located on the left and right sides of the conveying device. Specifically, each of the left and right moving devices includes two fixed plates 410 and two linear drive devices 420, and the linear drive devices 420 include but are not limited to cylinders, oil cylinders or electric push rods. Since the invention does not have high precision requirements for the spacing between the two material racks 300 on the same layer, as long as the two can place pads of corresponding lengths, in order to reduce manufacturing costs, all linear drive devices 420 in the invention are preferably cylinders. All fixed plates 410 are fixedly connected to the base 100, and each cylinder is installed on the corresponding fixed plate 410, and the telescopic rod of each cylinder is set inward; through two slide rail pairs, each mounting plate 210 is slidably connected to the two fixed plates 410, and the telescopic rod of each cylinder is fixedly connected to the outer surface of the corresponding mounting plate 210. It should be noted that the telescopic rods of the two cylinders on the same side are extended and retracted synchronously. When the telescopic rods of the two cylinders on the same side are extended at the same time, the lifting device 200 on this side slides inwards. When the telescopic rods of the two cylinders on the same side are retracted at the same time, the lifting device 200 on this side slides outwards, so that the spacing between the two lifting devices 200 is adjustable to accommodate pads of different lengths. It is understandable that even if each of the left-right moving devices only includes one fixed plate 410 and one cylinder, the left-right moving device can still drive the lifting device 200 to move left-right, but such a setting is likely to cause the cylinder to overload, and its service life is correspondingly shortened.

[0031] In addition, the conveying device can be an integral conveyor belt or composed of two independently controlled feeding conveyor belts 510. Since the integral conveyor belt cannot correct the offset pad strip, the conveying device in the invention is preferably composed of two independently controlled feeding conveyor belts 510, the upper surfaces of the two feeding conveyor belts 510 are aligned, the two feeding conveyor belts 510 are parallel to each other and spaced apart, and the setting direction of the two feeding conveyor belts 510 becomes the conveying direction of the conveying device. In order to avoid the pad strips from being piled up and unloaded, the front ends of the two feeding conveyor belts 510 are both installed with unloading conveyor belts 520, the two unloading conveyor belts 520 are aligned front and back, and the conveying speed of the unloading conveyor belts 520 is greater than the conveying speed of the feeding conveyor belts 510; when the pad strip is transported from the slower feeding conveyor belt 510 to the faster unloading conveyor belt 520, the distance between the pad strip and the next pad strip will be significantly pulled apart, thereby avoiding the pad strips from being piled up and unloading, and stabilizing the conveying rhythm of the invention. In order to save manufacturing costs, the conveying device further includes two conveying motors 530. Each of the feeding conveyor belt 510 and the corresponding unloading conveyor belt 520 share one conveying motor 530. The connection structure of the two can be referred to in Figure 3 The feeding conveyor belt 510 and the unloading conveyor belt 520 are synchronously driven through a sprocket chain transmission mechanism, the driving wheel 501 of the sprocket chain transmission mechanism is driven by the conveying motor 530, and the first driven wheel 521 of the sprocket chain transmission mechanism is connected to the unloading conveyor belt 520. At the same time, the chain 502 of the sprocket chain transmission mechanism is also meshed with a second driven wheel 511, and the second driven wheel 511 is connected to the feeding conveyor belt 510, wherein the module of the second driven wheel 511 is greater than the module of the first driven wheel 521. Since the transmission ratio of the second driven wheel 511 to the first driven wheel 521 is not one-to-one, when the second driven wheel 511 rotates by an angle a, the first driven wheel 521 rotates by an angle a+n. It can be understood that the connection structure between the feeding conveyor belt 510 and the unloading conveyor belt 520 is not limited to the above-mentioned connection structure. As long as there is a speed difference between the two and they share the same conveying motor 530, no matter what the connection structure between the two is, they are all within the protection scope of the invention.

[0032] In some embodiments of the present invention, the cushion strip may deviate during the conveying process. Since it is difficult to accurately place the deviated cushion strip on the claw of the conveyor belt, in order to correct the deviated cushion strip, each of the unloading conveyor belts 520 is provided with a first induction sensor (not shown in the drawings). Each of the first induction sensors is located at the front end of the corresponding unloading conveyor belt 520 and the two first induction sensors are horizontally aligned. Each of the first induction sensors senses in the direction of the cushion strip. The first induction sensors include but are not limited to proximity switches or photoelectric sensors. Each of the first induction sensors is connected to the corresponding conveying motor 530 for electrical signals. When the cushion strip deviates, one end of it first triggers the first induction sensor on one side, and the conveying motor 530 on the same side stops rotating until the other end of the cushion strip also triggers the first induction sensor on the other side. At this time, the cushion strip is corrected. If both of the first induction sensors are triggered, the two conveying motors 530 start working and convey the cushion strip to the claw of the conveyor belt.

[0033] In some embodiments of the invention, in order to enable the two lifting devices 200 to automatically descend after the multiple pads at the bottom layer are transported, a second induction sensor (not shown in the drawings) is provided between the two feeding conveyor belts 510. The second induction sensor is located at the front side of the material rack 300. The second induction sensor senses in the direction of the pads. The second induction sensor includes but is not limited to a proximity switch or a photoelectric sensor. The second induction sensor is connected to the drivers of the two lifting devices 200 by electrical signals. When the second induction sensor does not sense the pads within a specified time period (customizable), the driver drives the two lifting devices 200 to descend simultaneously. The descending height is the height of each layer of the material rack 300, so that the multiple pads at the second bottom layer can be lowered onto the two feeding conveyor belts 510.

[0034] Through the above settings, the present invention creates a workflow as follows:

[0035] 1. First, the distance between the two lifting devices 200 is adjusted by the two left and right moving devices so that a plurality of cushion strips of corresponding lengths can be placed therein, and each layer of the material rack 300 is filled with cushion strips manually;

[0036] 2. Control the driver to lower the two lifting devices 200 until the plurality of cushion strips located at the bottom layer can be lowered onto the two feeding conveyor belts 510;

[0037] 3. The two feeding conveyor belts 510 sequentially convey the plurality of cushion strips forward to the two unloading conveyor belts 520. After the two unloading conveyor belts 520 correct the positions of the cushion strips at the front ends, the two unloading conveyor belts 520 convey the cushion strips to the claws of the conveyor belts.

[0038] 4. If the second induction sensor does not sense the cushion strip within the specified time period, the driver drives the two lifting devices 200 to descend simultaneously, so that the plurality of cushion strips located at the second bottom layer can be lowered onto the two feeding conveyor belts 510;

[0039] 5. Repeat steps 3 and 4 in sequence until all the cushion strips have been delivered.

[0040] It should be further explained that, after step 4, there may be a sensing blank period, during which the second sensing sensor and the two first sensing sensors do not sense the cushion strip. In order to ensure the normal use of the invention, when the second sensing sensor and the two first sensing sensors do not sense the cushion strip, the two conveying motors 530 work normally until one of the first sensing sensors senses the cushion strip.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
