Description

Technical Field

[0001] The invention belongs to the technical field of interior fabric transfer, and in particular relates to an adhesive roller follower type material taking device, and also relates to an adhesive roller follower type material taking process. Background Art

[0002] At present, for some interior fabric processing (such as: car interior fabric), because the fabric itself is breathable and light, and although the fabric is not very soft, it is still easy to bend, deform or wrinkle. Therefore, when the stacked interior fabrics need to be transferred one by one by the robot, there will be the following defects:

[0003] 1) Not only can negative pressure adsorption (breathable properties) not be performed, but surface clamping will cause clamping marks, and surface clamping will increase the wrinkle rate of the fabric;

[0004] 2) If side clamping is used, the layers cannot be effectively separated. Therefore, the probability of two or more layers of fabric being transferred is high. At the same time, because the area of ​​the interior fabric must match many clamping points, a piece of interior fabric can be relatively flattened for transfer, and the flattening process will inevitably cause the fabric to be pulled or deformed. Therefore, the side clamping material collection method is difficult to meet the material collection needs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved adhesive roller follower type material taking device.

[0006] At the same time, the invention also relates to a sticking type roller follower type material taking process.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A sticking roller follower type material taking device, comprising:

[0009] Reclaim seat;

[0010] The feeding unit comprises a first feeding group and a second feeding group respectively having bonding parts, a first follower roller and a second follower roller which are slidably installed on a feeding seat and maintain a relative movement tendency to move closer, and a power module which drives the bonding parts of the first feeding group and the second feeding group to be synchronously retracted or extended, wherein the first feeding group and the second feeding group are arranged separately, and the first feeding group and the second feeding group respectively bypass the corresponding first follower roller and the second follower roller to form a first peeling angle and a second peeling angle, and the bonding parts are respectively formed on the outer sides of the first peeling angle and the second peeling angle, and each bonding part is synchronously extended, and the first follower roller and the second follower roller are followed to maintain relative proximity and reset, and the first peeling angle and the second peeling angle gradually decrease, and the bottom surface of each bonding part constitutes a feeding bonding surface that cooperates with the surface of a thin layer product; when each bonding part is retracted inward in the same direction, the first follower roller and the second follower roller are relatively separated, and the first peeling angle and the second peeling angle gradually increase and gradually separate from the feeding bonding surface while the thin layer product maintains a dynamic balance state.

[0011] Preferably, one side forming the first peeling angle and the second peeling angle is horizontally arranged, and the other side is inclined up and down to form an acute peeling angle; and the first peeling angle and the second peeling angle are arranged relative to each other from the tip of the acute angle. Based on the horizontal arrangement of the peeling edge, the material taking adhesive surface is relatively flush for the thin layer product to be pasted and adsorbed, and the deformation or wrinkle rate of the thin layer product is reduced under the effective contact formed by the two adsorption surfaces.

[0012] Furthermore, the first peeling angle and the second peeling angle are equal.

[0013] According to a specific implementation and preferred aspect of the present invention, the first peeling angle and the second peeling angle increase or decrease at the same rate as the bonding portion moves. That is, when unloading the product, the two first and second pick-up groups peel with the same force, so the peeling forces formed by the first and second peeling angles offset each other in the length direction of the thin layer product, thus achieving the thin layer product gradually separating from the pick-up bonding surface while maintaining a dynamic balance.

[0014] According to another specific implementation and preferred aspect of the present invention, the first material collection group includes a first unwinder; a first unwinding tape having one end fixed to the material collection seat and the other end passing through a first follower roller and then being wound to the first unwinder, wherein the first unwinding tape forms a first peeling angle; the second material collection group includes a second unwinder; a second unwinding tape having one end fixed to the material collection seat and the other end passing through a second follower roller and then being wound to the second unwinder, wherein the second unwinding tape forms a second peeling angle. Here, the peeling angle is changed based on the winding and unwinding of the tape, while the peeling is gradually performed under the premise of maintaining adhesion.

[0015] Preferably, the first winder and the second winder keep moving towards each other and rewind and unwind synchronously.

[0016] Furthermore, arc-shaped transition parts are formed at two opposite ends of the bottom of the material picking seat, the first unwinder is located above the side of the first follower roller, and the first unwinding belt includes a first belt body extending downward from the outside of the material picking seat and bypassing the arc-shaped transition part, a second belt body horizontally located between the arc-shaped transition part and the first follower roller, and a third belt body wound around the first follower roller and the first unwinder, wherein the second belt body and the third belt body constitute a first peeling angle, and the adhesive portion is located on the second belt body and / or the third belt body; the second unwinder is located above the side of the second follower roller, and the second unwinding belt includes a fourth belt body extending downward from the outside of the material picking seat and bypassing the arc-shaped transition part, a fifth belt body horizontally located between the arc-shaped transition part and the second follower roller, and a sixth belt body wound around the second follower roller and the second unwinder, wherein the fifth belt body and the sixth belt body constitute a second peeling angle, and the adhesive portion is located on the fifth belt body and / or the sixth belt body. Here, based on the layout direction of each belt body, on the one hand, a required peeling angle is formed; on the other hand, it is convenient to implement the synchronous expansion and synchronous retraction of the adhesive portion.

[0017] In some specific embodiments, the first belt body, the second belt body, and the third belt body are integrated and made of steel belt, and the bonding portion is a double-sided adhesive layer formed on the outside of the steel belt; and / or the fourth belt body, the fifth belt body, and the sixth belt body are integrated and made of steel belt, and the corresponding bonding portion is a double-sided adhesive layer formed on the outside of the steel belt. Based on the setting of the double-sided adhesive layer, not only is the formed adhesion effect good, but the replacement cost of the double-sided adhesive layer is low, and the formed adhesion area is easy to control.

[0018] According to another specific implementation and preferred aspect of the present invention, the power module includes a power motor, a first transmission wheel, a second transmission wheel, a first transmission member for connecting the first transmission wheel to the first winder, a second transmission member for connecting the second transmission wheel to the second winder, and a third transmission member for synchronously transmitting the power motor to the first transmission wheel and the second transmission wheel. The required synchronous and opposite rotations are implemented based on the same power motor. Preferably, the third transmission member includes a gear transmission group that synchronously meshes between the first transmission wheel and the second transmission wheel, and a transmission belt group that connects the power motor to one of the first transmission wheel and the second transmission wheel; the power module also includes a tensioning wheel arranged on the transmission path formed by the first transmission member, the second transmission member, and the transmission belt group. Based on the tensioning wheel, the transmission belt is prevented from slipping. In addition, the transmission formed is simple, and it is easier to implement the required opposite motion peeling, completely offsetting the peeling force.

[0019] Preferably, the first material taking group and the second material taking group are symmetrically arranged about the center of the interval, which is convenient for layout and more conducive to stable implementation.

[0020] In addition, the first follower roller and the second follower roller are symmetrically arranged, and both slide on the material picking seat from the shaft end, and each shaft end and the material picking seat are also provided with a reset tension spring to drive the shaft end to reset. That is to say, when the two winders unwind, the reset tension spring is combined to synchronously expand the bonding part outward to form a flush material picking bonding surface. Generally, when picking up materials, the material picking bonding surface is horizontally arranged and located below the second belt body; after unloading, the material picking bonding surface is located above the third belt body. Reduce the probability of accidental adhesion due to the exposed material picking bonding surface.

[0021] Another technical solution of the present invention is: a sticking roller follower type material taking process, which adopts the above-mentioned sticking roller follower type material taking device and includes the following steps:

[0022] S1. Pasting and taking materials for thin layer products

[0023] The material taking device is moved to the top of the thin product based on the movement, and the first follower roller and the second follower roller are kept relatively close to each other and reset during the synchronous extension of the two bonding parts, and the first peeling angle and the second peeling angle are gradually reduced, and the bottom surface of each bonding part forms a material taking bonding surface matching the surface of the thin product, and then the thin product is matched and pasted on the self-material taking bonding surface to complete the material taking;

[0024] S2. Unloading of thin layer products

[0025] After the material taking device is moved to the desired position, when the two bonding parts are retracted inward at the same time, the first follower roller and the second follower roller are relatively separated, the first peeling angle and the second peeling angle gradually increase and gradually separate from the material taking bonding surface while the thin layer product maintains a dynamic balance state to complete the unloading.

[0026] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0027] As for the processing of existing thin-layer products (such as automobile interior fabrics), not only is it impossible to perform negative pressure adsorption (due to the breathable characteristics), but surface clamping will also cause clamping marks. At the same time, surface clamping will increase the wrinkle rate of the fabric. In addition, if side clamping is used, it is impossible to effectively separate the layers. Therefore, the probability of two or more layers of fabric being transferred is high. At the same time, because the area of ​​the interior fabric must match many clamping points, a piece of interior fabric can be relatively flattened and transferred, and the flattening process will inevitably cause the fabric to be pulled or deformed. Therefore, the side clamping material collection method is difficult to meet the material collection needs and other shortcomings. The present application cleverly solves the various shortcomings of the existing structure by overall designing an adhesive roller follower type material collection device. After adopting the adhesive roller follower type material picking device, first, the material picking device is moved to the top of the thin layer product based on the movement, and at the same time, the two adhesive parts are synchronously extended, and the first follower roller and the second follower roller are kept relatively close to each other for reset, and the first peeling angle and the second peeling angle gradually become smaller, and the bottom surface of each adhesive part constitutes a material picking adhesive surface that matches the surface of the thin layer product, and then the thin layer product is matched and pasted on the self-material picking adhesive surface to complete the material picking; then, after the material picking device is moved to the desired position, when the two adhesive parts are retracted inwardly at the same time, the first follower roller and the second follower roller are relatively separated, and the first peeling angle and the second peeling angle gradually increase and gradually separate from the material picking adhesive surface while the thin layer product maintains a dynamic balance state to complete the material picking. Therefore, compared with the existing structure, the present invention, on the one hand, is based on the synchronous extension or synchronous retraction of the two adhesive parts, and cooperates with the relative movement of the follower roller to gradually change the peeling angle and the position of the adhesive part, so as to complete the self-adhesion and material collection of the thin layer product and keep the thin layer product in the original state to gradually peel off the material collection adhesive surface to complete the unloading, that is, reduce the deformation rate or wrinkle rate caused by the material collection and unloading of the thin layer product; on the other hand, based on the movement of the follower roller to change the size of the peeling angle, it can provide the maximum bonding area when picking up the material, reduce the deformation rate or the interlayer mis-picking rate that occurs when picking up the material, and when unloading, the peeling forces formed by the two peeling angles offset each other, so that the thin layer product gradually separates from the material collection adhesive surface while maintaining a dynamic balance state.

[0046] like Figures 1 to 8As shown, the adhesive roller follower type material picking device involved in this embodiment includes a material picking seat 1 and a material picking unit 2.

[0047] The material picking unit 2 includes a first material picking group 21 and a second material picking group 22 respectively having an adhesive portion N, a first follower roller 23 and a second follower roller 24 that maintain a relative movement trend and are slidably installed on the material picking seat 1, and a power module 25 that drives the adhesive portions of the first material picking group 21 and the second material picking group 22 to be synchronously retracted or extended.

[0048] In some specific embodiments, the first material picking group 21 and the second material picking group 22 are spaced apart, and the first material picking group 21 and the second material picking group 22 are symmetrically arranged about the center of the interval. This facilitates the layout and is more conducive to stable implementation. The first follower roller 23 and the second follower roller 24 are symmetrically arranged, wherein a horizontally extending slide 10 is provided on the material picking seat 1, and the first follower roller 23 and the second follower roller 24 slide from the shaft end in the slide 10 of the material picking seat 1, and each shaft end and the material picking seat 1 are also provided with a reset tension spring 26 for driving the shaft end to reset. The first material picking group 21 and the second material picking group 22 respectively bypass the corresponding first follower roller 23 and the second follower roller 24 to form a first peeling angle b1 and a second peeling angle b2, and the bonding parts N are respectively formed on the outer sides of the first peeling angle b1 and the second peeling angle b2. When each bonding part N is synchronously extended, the first follower roller 23 and the second follower roller 24 follow and are kept relatively close to each other by the reset spring 26. The first peeling angle b1 and the second peeling angle b2 gradually decrease, and the bottom surface of each bonding part N constitutes a material picking bonding surface that cooperates with the surface of the thin layer product; when each bonding part N is retracted inward in the same direction, the first follower roller 23 and the second follower roller 24 are relatively far away, and the first peeling angle b1 and the second peeling angle b2 gradually increase and gradually separate from the material picking bonding surface while the thin layer product maintains a dynamic balance state.

[0049] Furthermore, one side edge constituting the first peeling angle b1 and the second peeling angle b2 is horizontally arranged, and the other side edge is inclined up and down to form an acute angle of peeling; and the first peeling angle b1 and the second peeling angle b2 are arranged relative to each other from the corner tips of the acute angle. Based on the horizontal setting of the peeling edge, the material collection bonding surface is relatively flush for the thin layer product to be pasted and adsorbed, and the deformation or wrinkle rate of the thin layer product is reduced under the effective contact formed by the two adsorption surfaces. At the same time, the angles of the first peeling angle b1 and the second peeling angle b2 are equal. The angles of the first peeling angle b1 and the second peeling angle b2 increase or decrease at the same rate as the bonding part N moves. That is to say, when unloading the product, the two first material collection groups 21 and the second material collection group 22 maintain the same force for peeling, so the peeling force formed by the first peeling angle b1 and the second peeling angle b2 offset each other in the length direction of the thin layer product, and the thin layer product is gradually separated from the material collection bonding surface while maintaining a dynamic balance.

[0050] In this example, the first material collection group 21 includes a first unwinder 210; a first unwinding belt 211 fixed at one end to the material collection seat 1, and the other end passes through the first follower roller 23 and is wound to the first unwinder 210, wherein the first unwinding belt 211 forms a first peeling angle b1; the second material collection group 22 includes a second unwinder 220; a second unwinding belt 221 fixed at one end to the material collection seat 1, and the other end passes through the second follower roller 24 and is wound to the second unwinder 220, wherein the second unwinding belt 221 forms a second peeling angle b2. Here, the peeling angle is changed based on the winding and unwinding of the material belt, while the peeling is gradually carried out under the premise of maintaining adhesion.

[0051] The first unwinder 210 and the second unwinder 220 keep moving toward each other and rewind and unwind synchronously. A first arc transition portion h1 and a second arc transition portion h2 are formed at opposite ends of the bottom of the material pick-up seat 1, respectively. The first unwinder 210 is located above the side of the first follower roller 23, and the first unwinding belt 211 includes a first belt body a extending downward from the outside of the material pick-up seat 1 and bypassing the first arc transition portion h1, a second belt body b horizontally located between the first arc transition portion h1 and the first follower roller 23, and a third belt body c wound around the first follower roller 23 and the first unwinder 210, wherein the second belt body b and the third belt body c form a first peeling angle b1, and the bonding portion N is located on the second belt body b and / or the third belt body c. According to the principle of symmetry, the second unwinder 220 is located above and to the side of the second follower roller 24, and the second unwinding belt 221 includes a fourth belt body d extending downward from the outside of the material pick-up seat 1 and bypassing the second arc-shaped transition portion h2, a fifth belt body e horizontally located between the second arc-shaped transition portion h2 and the second follower roller 24, and a sixth belt body f wound around the second follower roller 24 and the second unwinder 220, wherein the fifth belt body e and the sixth belt body f constitute a second peeling angle b2, and the bonding portion N is located on the fifth belt body e and / or the sixth belt body f. Here, based on the layout direction of each belt body, on the one hand, the required peeling angle is formed; on the other hand, it is convenient to implement the synchronous expansion and synchronous retraction of the bonding portion. Furthermore, the first belt body a, the second belt body b, and the third belt body c are integrated and made of steel belt, and the bonding portion N is a double-sided adhesive layer formed on the outside of the steel belt; the fourth belt body d, the fifth belt body e, and the sixth belt body f are integrated and made of steel belt, and the corresponding bonding portion is a double-sided adhesive layer formed on the outside of the steel belt. Based on the setting of the double-sided adhesive layer, not only is the adhesion effect formed good, but the replacement cost of the double-sided adhesive layer is low, and the adhesion area formed is easy to control. When the two winders are unwinding, the reset tension spring 26 is combined at this time to synchronously expand the bonding portion N outward to form a flush material collection bonding surface. Generally, when taking materials, the material collection bonding surface is horizontally set and located below the second belt body b; after unloading, the material collection bonding surface is located above the third belt body c; reducing the probability of accidental adhesion due to the exposure of the material collection bonding surface. Similarly, the material taking adhesive surface of the second material taking group 22 is located below the fifth belt body e when taking materials, and is located above the sixth belt body f when unloading materials.

[0052] The power module 25 includes a power motor 250, a first transmission wheel 251, a second transmission wheel 252, a first transmission member 253 for connecting the first transmission wheel 251 to the first reel 210, a second transmission member 254 for connecting the second transmission wheel 252 to the second reel 220, and a third transmission member 255 for synchronously driving the power motor 250 with the first transmission wheel 251 and the second transmission wheel 252. The required synchronization and opposite rotation are implemented based on the same power motor 250. Preferably, the third transmission member 255 includes a gear transmission group g for synchronously meshing between the first transmission wheel 251 and the second transmission wheel 252, and a transmission belt group m for connecting the power motor 250 to one of the first transmission wheel 251 and the second transmission wheel 252; the power module 25 also includes a tensioning wheel 256 arranged on a transmission path formed by the first transmission member 253, the second transmission member 254, and the transmission belt group m. The tensioning wheel 256 avoids the transmission belt from slipping. In addition, the transmission formed is simple and it is easier to implement the required opposite movement peeling, which completely offsets the peeling force.

[0053] In summary, the implementation process of this embodiment is as follows:

[0054] S1. Pasting and taking materials for thin layer products

[0055] The material taking device is moved to the top of the thin product based on the movement, and the first follower roller and the second follower roller are kept relatively close to each other and reset during the synchronous extension of the two bonding parts, and the first peeling angle and the second peeling angle are gradually reduced, and the bottom surface of each bonding part forms a material taking bonding surface matching the surface of the thin product, and then the thin product is matched and pasted on the self-material taking bonding surface to complete the material taking;

[0056] S2. Unloading of thin layer products

[0057] After the material taking device is moved to the desired position, when the two bonding parts are retracted inward at the same time, the first follower roller and the second follower roller are relatively separated, the first peeling angle and the second peeling angle gradually increase and gradually separate from the material taking bonding surface while the thin layer product maintains a dynamic balance state to complete the unloading.

[0058] In summary, after adopting the adhesive roller follower type material picking device, first, the material picking device is moved to the top of the thin layer product based on the movement, and at the same time, the two adhesive parts are synchronously extended, and the first follower roller and the second follower roller are kept relatively close to reset, the first peeling angle and the second peeling angle gradually become smaller, and the bottom surface of each adhesive part constitutes a material picking adhesive surface that matches the surface of the thin layer product, and then the thin layer product is matched and pasted on the self-material picking adhesive surface to complete the material picking; then, after moving the material picking device to the desired position, when the two adhesive parts are retracted inward at the same time, the first follower roller and the second follower roller are relatively separated, the first peeling angle and the second peeling angle gradually increase and gradually separate from the material picking adhesive surface while the thin layer product maintains a dynamic balance state to complete the unloading, so Compared with the existing structure, the present invention, on the one hand, is based on the synchronous extension or synchronous retraction of the two adhesive parts, and cooperates with the relative movement of the follower roller to gradually change the peeling angle and the position of the adhesive part, so as to complete the self-adhesion and material collection of the thin layer product and keep the thin layer product in the original state to gradually peel off the material collection adhesive surface to complete the unloading, that is, reduce the deformation rate or wrinkle rate caused by the material collection and unloading of the thin layer product; on the other hand, based on the movement of the follower roller to change the size of the peeling angle, it can provide the maximum adhesive area when picking up the material, reduce the deformation rate or the interlayer mis-picking rate when picking up the material, and when unloading, the peeling forces formed by the two peeling angles offset each other, so that the thin layer product gradually separates from the material collection adhesive surface while maintaining a dynamic balance state; thirdly, based on the horizontal setting of the peeling edge, The material picking adhesive surface is relatively flush for the thin layer product to be pasted and adsorbed, and the deformation or wrinkle rate of the thin layer product is reduced under the effective contact formed by the two adsorption surfaces. At the same time, the angles of the first peeling angle and the second peeling angle are equal, and the angles of the first peeling angle and the second peeling angle increase or decrease at the same rate as the bonding part moves. That is to say, when unloading the product, the two first material picking groups and the second material picking groups maintain the same force for peeling, so the peeling forces formed by the first peeling angle and the second peeling angle offset each other in the length direction of the thin layer product, thereby achieving the thin layer product gradually separating from the material picking adhesive surface while maintaining a dynamic balance state; the fourth aspect is based on the winding and unwinding of the material tape to change the peeling angle, and at the same time, gradually peeling while maintaining adhesion, the first winding and unwinding The device and the second unwinder maintain opposite movement and synchronous rewinding and unwinding, and then based on the layout direction of each belt body, not only the required peeling angle is formed, but also it is convenient to implement the synchronous expansion and synchronous retraction of the bonding part; the fifth aspect adopts the setting of steel belt and double-sided adhesive layer, not only the formed adhesion effect is good, but also the replacement cost of the double-sided adhesive layer is low, and the formed adhesion area is easy to control; the sixth aspect is based on the same power motor to implement the required synchronous and opposite rotation, and the tension wheel avoids the transmission belt from slipping. In addition, the transmission formed is simple, and it is easier to implement the required opposite movement peeling, completely offsetting the peeling force; the seventh aspect is that the first material taking group and the second material taking group are symmetrically arranged about the interval center, which is convenient for layout and more conducive to stable implementation;In the eighth aspect, when the two winders unwind, the reset spring is combined to synchronously expand the bonding part outward to form a flush material collection bonding surface. Generally, when taking materials, the material collection bonding surface is horizontally set and located below the second belt body; after unloading, the material collection bonding surface is located above the third belt body, reducing the probability of accidental adhesion due to the exposure of the material collection bonding surface (similar to hidden protection). ;
