Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Nowadays, automation has become one of the development trends of various industries around the world. In an automatic production line, the use of adhesive tapes is increasing. The common single roll of adhesive tape is generally only dozens of meters long, the service life is short, and the adhesive tape roll needs to be frequently replaced, which greatly affects the efficiency of the production line. One way to improve efficiency is to replace the conventional single roll tape roll with a horizontally wound tape roll, also known as a bobbin. The horizontally wound tape roll is obtained by winding a layer of tape on an elongated reel in a multi-turn side-by-side manner, and then continuously winding a plurality of layers of tape on the layer of tape in a multi-turn side-by-side manner, and each layer of tape generally forms a fixed crossing angle therebetween, and is wound like a wound yarn, and thus is called a yarn roll tape. Compared with a single-roll adhesive tape with only one turn per layer, the wool coil adhesive tape has larger volume, can be wound longer, and is used for a longer time. In the case of the wool roll, in order to prevent tapes from sticking to each other when they are arranged side by side and stacked, release films are generally provided on both surfaces of the tapes. Wherein the first release film covers the first adhesive surface. The second release film covers the second adhesive surface and extends to at least a portion of the two side surfaces to prevent tape blocking. At present, the application system of the double centrifugal film adhesive tape is not highly automated and is complicated in structure.

Tape applicators are designed in a multitude of ways and have a very strong market demand, but most of the equipment is designed for specific operating conditions and integrated in a customized production line.

Detailed Description

The detailed structure and the operation principle of the adhesive tape applying machine according to the present invention will be described with reference to the accompanying drawings.

Fig. 1 and 2 show a machine for applying a wool-roll tape according to the invention in perspective view. The machine 1 for applying a yarn-wound tape according to the present invention comprises an unwinding mechanism 100, an applying mechanism 200, and a connecting mechanism 300 as a whole, wherein the unwinding mechanism 100 and the applying mechanism 200 are connected to the connecting mechanism 300. Here, the unwinding mechanism 100 is used to unwind the adhesive tape 101 wound in the form of a bobbin of knitting wool and having a layered structure as shown in fig. 7a and 7b from the tape roll 102 and separate the first release film 103 attached to the adhesive layer 104 of the adhesive tape from the adhesive tape. The adhesive tape 101, from which the first release film has been unwound and removed, is guided to the application mechanism 200. The adhesive tape is applied to the corresponding target product or site by the adhesive tape applying mechanism 200 and the second release film 105 attached on the other side of the adhesive layer 104 is subjected to recovery winding. The connecting mechanism 300 of the tape dispenser according to the present invention is also used to connect the tape dispenser 1 to other devices or systems, such as an automated robotic system or automated equipment, so as to flexibly position the tape dispenser by the robotic system or automated equipment.

The unwinding mechanism 100 of the adhesive tape application machine 1 according to the present invention will be described with reference to the accompanying drawings. As described above, the tape application machine 1 according to the present invention is particularly suitable for an adhesive tape wound in a form of a bobbin and having release films on both sides. Therefore, before applying the adhesive tape, it is necessary to unwind the adhesive tape from the wool roll, remove a release film on the surface of the adhesive tape, and then transfer the adhesive tape with a release film to an application mechanism. To this end, the unwinding mechanism 100 includes a bracket 110, a release film separating part 120, a first release film take-up roller 140, and a guide roller 160.

The support 110 is used for supporting the release film separating part 120, the first release film take-up roll 140, the guide wheel 160 and the tape roll 102, and is connected with the connecting mechanism 300 located therebelow. The support 110 includes a base 112 supported on a base 310 of the coupling mechanism 300 and coupled to the base 310, a first support 114 for supporting the first release film take-up roll 140, a second support 116 for supporting the guide pulley 160, a third support 118 disposed between the first support 114 and the second support 116, and a fourth support 119. The third support part 118 is used to support a guide roller 122 and a steering roller 124 of the release film separating part 120, and has a substantially inverted "T" shape. The fourth supporting portion 119 is used to support the tape roll 102 and the motor 180 for driving the tape roll to unwind. The base 112 may be, for example, an "L" shaped member including first and second portions 1121, 1122 that are generally perpendicular to each other. The first portion 1121 is used to fixedly attach the unwind mechanism 100 to the base 310. First support 114 and second support 116 extend from second portion 1122 along a plane parallel to second portion 1122 such that the three form a generally Y-shaped configuration. For convenience of description, a plane in which the first supporting portion 114 and the second supporting portion 116 are located is hereinafter referred to as a supporting plane. The third support portion 118 is connected to both the first support portion 114 and the second support portion 116. The fourth support 119 is connected to the second portion 1122 of the base.

The first support portion 114 of the cradle 110 has a release film take-up shaft 1141 extending in a direction substantially perpendicular to the support plane. The first release film take-up roll 140 is provided on the release film take-up shaft 1141 and can rotate. The second support portion 116 has a guide roller shaft 1161 extending substantially parallel to the release film take-up shaft 1141. Idler 160 is disposed on idler shaft 1161 and is rotatable about idler shaft 1161. Because according to the utility model discloses a machine is used to sticky tape can unwind the knitting wool book sticky tape, consequently when rolling up the one deck sticky tape side by side and unwinding to the knitting wool, leaves the position of the axial direction of the sticky tape that the knitting wool book was unwound along the dabber that the knitting wool was rolled up at the unwinding in-process and is constantly along the axial direction drunkenness. In order to accommodate this unwinding of the wool-wound tape to always position the tape in the center of the guide wheel 160 and to prevent the tape from coming off the guide wheel 160 during the unwinding, the guide wheel 160 has an axisymmetric structure with thicker ends and thinner middle, that is: the diameters of the two end parts of the guide wheel are larger than that of the middle part. In addition, as shown in fig. 3, the guide roller 160 and the first release film take-up roller 140 are disposed at opposite sides of the guide roller 122 so as not to interfere. This structure is also suitable for tape rolls having different tape winding directions.

The third support portion 118 of the bracket 110 has a guide roller shaft 1181 and a steering roller shaft 1182 extending in a direction perpendicular to the support surface. The guide roller 122 and the steering roller 124 are provided on the guide roller shaft 1181 and the steering roller shaft 1182, respectively, and are rotatable on the guide roller shaft 1181 and the steering roller shaft 1182. Generally, the release film take-up shaft 1141, the guide roller shaft 1161, the guide roller shaft 1181, and the steering roller shaft 1182 are disposed parallel to each other. Generally, in order to be suitable for unwinding the bobbin tape, the lengths of the release film take-up shaft 1141, the guide roller shaft 1161, the guide roller shaft 1181, and the steering roller shaft 1182 are equal to or greater than the axial length of the bobbin.

The unwinding process of the adhesive tape 101 will be described in detail below. As the tape roll 102 rotates in the unwinding direction, the tape 101 leaves the tape roll 102, and thereafter, the first release film 103 is separated at the release film separating part 120. Specifically, the tape 101 unwound from the tape roll 102 is guided to the guide roller 122. At guide roller 122, first release film 103 is separated from tape 101 and guided to first release film take-up roller 140. The first release film take-up roll 140 winds and recovers the separated first release film 103. The adhesive tape 101 from which the first release film 103 is removed is guided to a steering roller 124 of the adhesive tape in a direction different from the traveling direction of the first release film 103. The adhesive tape 101 diverted at the diverting roller 124 is continuously guided forward to the guide roller 160. At guide wheel 160, tape 101 is guided to applicator 200. Fig. 3 schematically shows the unwinding and guiding process of the adhesive tape. During this guiding of the adhesive tape, the second release film 105 of the adhesive tape opposite to the first release film 103 is in contact with the steering roller 124 and the guide roller 160 so as not to contaminate the adhesive layer 104 of the adhesive tape, as shown in fig. 7a and 7 b.

The adhesive tape applying mechanism 200 of the adhesive tape applying machine 1 according to the present invention will be described with reference to the accompanying drawings. Specifically, as shown in fig. 2 and 4, the adhesive tape 101 guided to the tape application mechanism 200 by the guide wheel 160 is applied to the corresponding target product or site at the tape application mechanism 200. As shown in fig. 2 and 4, the tape application mechanism 200 includes a base plate 210, and the tape application mechanism 200 is fixedly mounted on a base 310 of the connection mechanism 300 through the base plate 210. The surface of the substrate 210 is provided with two support portions extending out of the substrate parallel to the surface of the substrate, namely: a first support part 220 and a second support part 240. The first support part 220 is provided with a first guide roller 221 extending generally perpendicular to the surface of the substrate. The second supporting portion 240 is provided with a second release film take-up roll 241 for recovering the second release film 105. The second support 240 is further provided with a motor 280 for driving the second release film take-up roll 241. A tape application head 250 for applying a tape to a desired portion is provided on the substrate 210. The second guide wheel 222 and the third guide wheel 223 are disposed on the surface of the substrate and serve to guide the tape toward the tape application head 250. After the tape is applied to the target product or site, the remaining second release film 105 is guided to the second release film take-up roll 241 by the fourth guide wheel 224, the fifth guide wheel 225, and the sixth guide wheel 226 provided on the surface of the substrate, thereby being recovered. Generally, the first to sixth guide wheels are disposed perpendicular to the substrate 210. It will be appreciated that the number and location of these guide wheels can be adjusted as appropriate.

It should be noted that, during the unwinding of the adhesive tape 101 and the winding and recovering of the first release film 103 and the second release film 105, in order to ensure that the adhesive tape and the first release film and the second release film can be tensioned with a proper tension throughout the process to facilitate the application of the adhesive tape and the winding of the release film, the adhesive tape, the first release film and the second release film need to have the same linear speed in synchronization during the process of being guided. In the prior art, for the unwinding of the adhesive tape roll and the winding recovery of the first release film and the second release film, motors are usually separately provided for the unwinding of the adhesive tape, the winding of the first release film and the winding of the second release film, that is, at least three motors are provided. It should be understood that the diameter of the tape roll may gradually decrease during unwinding of the tape roll, and the diameter of the rolls of the first and second release films may gradually increase during winding and recovering of the first and second release films. Then, in order to ensure constant linear speeds of the adhesive tape, the first release film and the second release film during the operation of the adhesive tape applicator, the rotational speeds of the three motors need to be adjusted in real time. In this case, however, a large number of motors are used and the control system is complicated, so that the cost of the tape applicator is high.

In order to solve the above problem, according to the utility model discloses a machine is used to sticky tape has only adopted two motors, and a motor is used for the unwinding of sticky tape, and another motor is used for the second to retrieve from the coiling of type membrane to do not set up the motor for the first coiling from the type membrane, but through simple rotation control mechanism when retrieving for the first coiling from the type membrane and provide power, make the unwinding of sticky tape in fourth supporting part 119 department and the first coiling from the type membrane in first coiling from type membrane wind-up roll department go on with the same linear velocity.

Specifically, as shown in fig. 1 and 5, a motor 180 is provided on the bracket 110. The motor 180 is disposed at an opposite side of the fourth support 119 from the tape roll 102. The fourth support 119 includes a unwinding shaft 117. The motor 180 is used to power the rotation of the unwind shaft 117. The unwinding shaft 117 rotates the tape roll 102 to unwind the tape. Meanwhile, the unwinding shaft 117 transmits the rotational power to the first release film take-up roll 140 through the transmission mechanism of the rotation control mechanism. Specifically, the transmission mechanism includes a first pulley 151 provided on the unwinding shaft 117, a second pulley 152 provided on a release film take-up shaft 1141 supporting the first release film take-up roller 140, and a timing belt 153 coupling the first pulley 151 and the second pulley 152. Wherein the first pulley 151 rotates in synchronization with the unwinding shaft 117. The first pulley 151 rotates the second pulley 152 via the timing belt 153. The outer diameter of the fully-wound knitting wool is D1, and the outer diameter of the first release film take-up roll 140 when the first release film is not wound is D2. When the respective diameters D1, D2, D1, and D2 satisfy the following formula (1), theoretically, the linear speed of unwinding the adhesive tape is always equal to or less than the winding speed of the first release film.

During unwinding of the tape, D1 became smaller and D2 became larger. In this case, if the first pulley 151 and the second pulley 152 are rotated in synchronization, the winding speed of the first release film with respect to the unwinding speed of the adhesive tape is gradually increased. In order to keep the linear velocity of the first release film when the first release film is wound up and the linear velocity of the adhesive tape when the adhesive tape is unwound, a rotation control mechanism is provided between the first release film supporting take-up roll 140 and the unwinding shaft 117. The second pulley 152 and the first release film take-up roll 140 are both mounted on the release film take-up shaft 1141. When the first linear velocity when leaving the rolling of type membrane for the sticky tape when unwinding linear velocity grow, rotation control mechanism can make first produce relative rotation between type membrane wind-up roll 140 and the second band pulley, promptly: the first release film take-up roll 140 slips relative to the second pulley, thereby reducing the linear velocity of the first release film relative to the second pulley. In this way, the consistency of the linear speed of the unwinding of the adhesive tape and the winding of the first release film is realized.

The rotation control mechanism used is described in detail below. As shown in fig. 6a-6c, the release film take-up reel 1141 includes a driving shaft portion 1142 and a driven shaft portion 1143. The first release film take-up roll 140 is provided on the driven shaft portion 1143. The second pulley 152 is fixed to the driving shaft portion 1142 and rotates the driving shaft portion 1142. The driving shaft portion 1142 rotates the driven shaft portion 1143 via the spring plunger 190. In the exemplary embodiment shown, the drive shaft portion 1142 has a small diameter portion 1144, and the driven shaft portion 1143 has a shaft hole 1145 extending axially thereof. The small diameter portion 1144 is disposed in the shaft hole 1145. A radial hole 1147 extending in the radial direction of the passive shaft portion 1143 extends through the peripheral wall of the shaft hole 1145. The spring plunger 190 is disposed in the radial hole 1147 and is biased into contact with the outer periphery of the small diameter portion 1144. The plurality of spring plungers 190 are provided in an axisymmetric manner in the circumferential direction of the driven shaft portion. When the torque transmitted through the driving shaft portion 1142 is smaller than a set value, the driving shaft portion 1142 drives the driven shaft portion 1143 to rotate by the friction torque between the spring plunger 190 and the small diameter portion; when the transmitted torque is greater than a set value, the spring plunger 190 slides on the surface of the small diameter portion 1144, causing relative rotation between the drive shaft portion 1142 and the driven shaft portion 1143. Thus, the spring plunger is also referred to as a slipping mechanism. In this way, it is possible to drive the first release film take-up roll 140 at a constant torque and to make the first release film travel at the same linear speed as the adhesive tape. When the speed of the first release film take-up roll and the speed of the second release film take-up roll are different, the first release film take-up roll 140 slips relative to the driving shaft portion 1142 through the rotation control mechanism, and therefore the linear speed the same as that of the adhesive tape is achieved. Conceivably, the shaft hole can also be arranged on the driving shaft part, and the driven shaft part is provided with a small-diameter part; the same effect can be achieved by the spring plungers being correspondingly arranged through radial holes provided in the drive shaft part. The transmission mechanism and the release film winding shaft 1141 form a rotation control mechanism of the invention. It is contemplated that one of ordinary skill in the art can configure other types of rotation control mechanisms as long as the relative rotation between the first release film take-up roll 140 and the second pulley 152 can be achieved when the transfer torque is greater than the set value. Likewise, those skilled in the art can arrange other transmission mechanisms as long as the rotation power of the unwinding shaft can be transmitted to the release film winding shaft.

According to the utility model discloses an above-mentioned structure to simple structure has realized first from the synchronous marcing of type membrane with the sticky tape, has saved driving motor's quantity, and its control system is simple.

According to another aspect of the present invention, the unwinding mechanism 100 can be applied to the adhesive tape roll wound in different winding manners. Fig. 7a and 7b show two unwinding methods for two different tape winding methods. The winding of fig. 7a is such that the first release film 103 is located radially outside the adhesive layer 104 of the tape 101 on the tape roll and the second release film 105 is located radially inside the adhesive layer 104. The winding of fig. 7b is such that the first release film 103 is located radially inside the adhesive layer 104 of the tape and the second release film 105 is located radially outside the adhesive layer 104 on the tape roll. For the two winding methods, when unwinding, it is only necessary to set the mounting direction of the adhesive tape roll and the rotation direction of the motor 180 for unwinding for the specific winding method, and it is not necessary to adjust the structure of the unwinding mechanism. In both cases, the second release film-bearing adhesive tape 101 enters the tape applicator 200 through the guide roller 160 at the same angle.

As shown in fig. 1 and 8, according to still another aspect of the present invention, the adhesive tape application machine 1 according to the present invention has a connection mechanism 300 adapted to connect the unwinding mechanism 100 and the application mechanism 200 together and to connect the adhesive tape application machine 1 with the robot device or the automation apparatus. The attachment mechanism 300 has a base 310. The base 310 has a top surface 311, side surfaces 312 opposite to each other, and side surfaces 313. The support 110 of the unwinding mechanism 100 is fixedly connected to the top surface 311 of the base 310. The base plate 210 of the application mechanism 200 is fixedly connected to the side 313. A connecting flange 350 can be provided on a side 312 of the base 310 opposite the side 313. As shown in fig. 9, the connection flange 350 is a component capable of being quickly connected with a component 400 of a robot arm, an automation device, or an automation line. The attachment flange 350 can be a standard piece. The design makes the whole adhesive tape applying machine 1 very compact in structure, and can realize flexible and quick connection with a robot, an automatic device or an automatic production line.
