Patent Description:
The present disclosure relates to the technical field of coiled tape, and in particular to a coiled tape material guiding machine. A prior art coiled tape material guiding machine is disclosed in <CIT>.

Currently, for guiding a coiled tape material to a next station of a production line, a material guiding roller group is usually used.

The material guiding roller group includes an upper roller and a lower roller. The coiled tape material is putted into a space between the upper roller and the lower roller, and is driven to the next station under rolling friction of the rollers. For putting the coiled tape material into the space between the upper roller and the lower roller, a usual way is to pull the coiled tape material manually into the space.

The above way is slow, resulting in not only low efficiency of the production line, but also a high danger and a waste of manpower and material resources.

In view of this, a problem to be solved by those skilled in the art is how to improve the way of guiding a material into a material guiding roller group.

To solve the above technical problem, the present disclosure provides a coiled tape material guiding machine, to guide the coiled tape material into a material guiding roller group efficiently.

A coiled tape material guiding machine is provided. The coiled tape material guiding machine includes a base and a material guiding roller group provided on the base. The machine further includes a material guiding portion configured to receive an extending end of a coiled tape, and guide the extending end to enter into the material guiding roller group.

The coiled tape material guiding machine is provided with the material guiding portion configured to receive the extending end of the coiled tape and guide the extending end into the material guiding roller group. Compared with the conventional way of guiding a material manually, the efficiency of guiding the material is improved, the manpower and material resources are saved, and the safety factor of operation is increased.

The material guiding portion is hinged to the base, and a pitch angle of the material guiding portion is adjustable to receive the extending end.

The coiled tape material guiding machine further includes a pitch driving device configured to drive the gripping assembly to pitch relative to the base.

The material guiding portion includes a guiding plate. The guiding plate is configured to pitch relative to the base. An upper surface and a lower surface of the guiding plate each forms a guiding surface. The guiding plate is configured to guide the extending end into the material guiding roller group via the upper surface or the lower surface.

The coiled tape material guiding machine further includes a baseplate. A relative position of the baseplate to the material guiding roller group is fixed. The baseplate and the guiding plate are both in a triangular shape. Upper surfaces and lower surfaces of the baseplate and the guiding plate are each a slope. Bottoms of the baseplate and the guiding plate are hinged together.

The guiding plate is configured to pitch to form, by cooperation of the upper surfaces of the guiding plate and the baseplate or by cooperation of the lower surfaces of the guiding plate and the baseplate, a guiding surface fitting the extending end.

The coiled tape material guiding machine may further include a material guiding box installed on the base. The material guiding roller group may be arranged in the material guiding box. The baseplate and the guiding plate may be installed to the material guiding box. The guiding plate may be configured to pitch relative to the material guiding box.

The coiled tape material guiding machine may further include a sliding platform installed on the base. The material guiding box may be installed on the sliding platform, and the sliding platform may be configured to slide relative to the base, to be close to or away from the coiled tape.

In order to make the person skilled in the art better understand the technical solutions of the present disclosure, the technical solution will be described completely hereinafter in conjunction with the drawings and embodiments of the present disclosure.

Reference is made to <FIG>, which is a schematic structural diagram of a coiled tape material guiding machine according to a first embodiment of the present disclosure.

A coiled tape material guiding machine in the embodiment is provided with a material guiding portion. The material guiding portion includes a gripping assembly. The gripping assembly includes a first picking plate <NUM> and a second picking plate <NUM>. As shown in <FIG>, the first picking plate <NUM> and the second picking plate <NUM> are arranged in an upper position and a lower position respectively. The first picking plate <NUM> and the second picking plate <NUM> are capable of open and close. When the first picking plate <NUM> and the second picking plate <NUM> are open, a coiled tape <NUM> can enter into a space between the two plates, and then the first picking plate <NUM> and the second picking plate <NUM> are closed to grip the coiled tape <NUM>, so as to guide the coiled tape <NUM> into a material guiding roller group <NUM>. The material guiding roller group as shown in <FIG> includes two upper rollers and a lower roller.

In addition, the coiled tape material guiding machine further includes a pitch driving device configured to drive the gripping assembly to pitch relative to a base <NUM>. In the embodiment, the gripping assembly and the material guiding roller group <NUM> are both arranged on a material guiding box <NUM>. The material guiding roller group <NUM> is located in the material guiding box <NUM> for protection. A most part of the gripping assembly is arranged outside the material guiding box <NUM>, to facilitate the entering of the coiled tape <NUM>. In addition, the material guiding box <NUM> is arranged on a sliding platform <NUM>. The sliding platform <NUM> is slidably connected to the base <NUM>.

In this case, the pitch driving device (no shown in the figure) drives the whole material guiding box <NUM> to pitch relative to the sliding platform <NUM>. Thus the material guiding box <NUM> and the gripping assembly thereon pitch relative to the base <NUM>. The position of the base <NUM> relative to a reel <NUM> is fixed, and thus the gripping assembly pitches relative to the reel <NUM>. The material guiding box <NUM> is hinged to the sliding platform <NUM>. The pitch driving device may be an oil cylinder, a gas cylinder, or the like.

Since the gripping assembly can pitch relative to the reel <NUM>, a pitch angle of the gripping assembly may be adjusted based on an actual situation of the coiled tape <NUM>. The actual situation of the coiled tape <NUM> mainly includes an angle, a bending degree, a location and an extending path of an extending end <NUM> (a start part of the coiled tape) of the coiled tape <NUM>. The pitch angle of the gripping assembly is adjusted to receive the extending end <NUM> of the coiled tape <NUM>, so that the extending end <NUM> enters into a space between the first picking plate <NUM> and the second picking plate <NUM> when the reel <NUM> rotates.

Reference is made to <FIG>. <FIG> is a schematic view showing that the coiled tape <NUM> is guided from a position above the coiled tape material guiding machine according to <FIG>. <FIG> is a schematic view showing that the coiled tape <NUM> is driven by the material guiding roller group <NUM> after being guided according to <FIG>. <FIG> is a schematic view showing that the coiled tape <NUM> is guided from a position below the coiled tape material guiding machine according to <FIG>. <FIG> is a schematic view showing that the coiled tape <NUM> is driven by the material guiding roller group <NUM> after being guided according to <FIG>.

As shown in <FIG>, when a material is guided from above (that is, the extending end <NUM> extends from an upper side of the reel <NUM> when the reel <NUM> rotates), the pitch driving device drives the material guiding box <NUM> to be inclined upward, and the gripping assembly hereby slopes upward to face to the extending end <NUM> of the coiled tape <NUM>. The extending end <NUM> then enters into the space between the first picking plate <NUM> and the second picking plate <NUM>.

As shown in <FIG>, when the extending end <NUM> enters into the space between the first picking plate <NUM> and the second picking plate <NUM>, the first picking plate <NUM> and the second picking plate <NUM> are closed. The pitch driving device drives the material guiding box <NUM> to return to a horizontal position, and the gripping assembly and the material guiding roller group <NUM> are hereby in the horizontal position. The extending end <NUM> keeps extending and enters into the material guiding roller group <NUM>, and then is driven horizontally to a next station.

<FIG> show a process of guiding a material from below (that is, the extending end <NUM> extends from a lower side of the reel <NUM> when the reel <NUM> rotates). The process is similar to the above process of guiding a material from above, only differing in that the material guiding box <NUM> is inclined downward, and the gripping assembly thereon also slopes downward to face to the extending end <NUM> of the coiled tape <NUM>.

The first picking plate and the second picking plate of the gripping assembly in the embodiment are capable of open and close. An opening angle between the first picking plate and the second picking plate is adjustable for better receiving the extending end <NUM> of the coiled tape <NUM>. For example, if the coiled tape <NUM> extends upward or downward greatly, the coiled tape <NUM> can also be guided into the gripping assembly by adjusting the opening angle. Therefore, the coiled tape material guiding machine is adaptive to various conditions without requiring manual adjustment.

In the embodiment, an end of the first picking plate <NUM> is hinged to an end of the second picking plate <NUM>. A first opening-closing driving component <NUM> and a second opening-closing driving component <NUM> are installed to the material guiding box <NUM>. The first opening-closing driving component <NUM> drives the first picking plate <NUM> to pitch, and the second opening-closing driving component <NUM> drives the second picking plate <NUM> to pitch. That is, the gripping assembly is in a structure similar to a scissor, to realize control of opening and closing. The first opening-closing driving component <NUM> and the second opening-closing driving component <NUM> each may be a hydraulic cylinder, a gas cylinder, or some other conventional driving component. In the structure, the opening angle can be controlled in a wide range, thereby easily receiving the extending end <NUM>.

It is understood that, the structure of the first picking plate <NUM> and the second picking plate <NUM> is not limited to the above. For example, the first picking plate <NUM> and the second picking plate <NUM> may be arranged in parallel, with a large or small distance therebetween. This structure can also guide the extending end <NUM> by only adjusting the pitch angle. It is more flexible to guide the coiled tape by using the "scissor" structure, because the "scissor" structure, in corporate with the adjustment of the pitch angle of the entire gripping assembly, can guide the extending end <NUM> in more conditions. In addition, the extending end <NUM> is slightly guided when the gripping assembly in the "scissor" structure is closed, facilitating the guide of the extending end <NUM> to the material guiding roller group <NUM>.

In fact, the way of only providing the two picking plates in the "scissor" structure can also realize picking and gripping a material. For example, during a process of guiding a material from above, the two picking plates are both inclined upward, but the first picking plate <NUM> is inclined upward in a greater angle. During a process of guiding a material from below, the two picking plates are both inclined downward, but the second picking plate <NUM> is inclined downward in a greater angle. Apparently, the way of pitching the entire gripping assembly and controlling the opening and closing of the two picking plates as shown in <FIG> is more adaptive and more reliable.

It is noted that, the gripping assembly in the present disclosure is not configured to clamp the coiled tape <NUM> tightly. Instead, it is configured to clamp the coiled tape <NUM> gently, and guide the coiled tape <NUM> to move, along a direction determined by the gripping assembly, to the material guiding roller group <NUM>. That is, the gripping assembly plays a role of guiding, rather than limiting the movement of the coiled tape <NUM>. Once the coiled tape <NUM> enters into the material guiding roller group <NUM>, the gripping assembly may releases the coiled tape <NUM>, so that the coiled tape <NUM> is driven to the down steam only by the material guiding roller group <NUM>.

In the embodiment, the material guiding box <NUM> is provided. The material guiding roller group <NUM> is arranged in the material guiding box <NUM> for protection. The material guiding box <NUM> is driven to pitch, to realize pitching control of the gripping assembly. It is understood that, it is feasible to merely drive the gripping assembly to pitch. As a whole, a pitching degree of the gripping assembly is greater if the whole material guiding box <NUM> pitches, and thus the scope for receiving the extending end <NUM> of the coiled tape <NUM> is wider, facilitating the gripping. Additionally, when the whole material guiding box <NUM> pitches, a position relation between the gripping assembly and the material guiding roller group <NUM> in the material guiding box <NUM> is not impacted by the change of the pitch angle, facilitating the guide of the coiled tape <NUM> into the material guiding roller group <NUM> in the material guiding box <NUM>, without complex control.

In the embodiment, because the next station is horizontally arranged, the material guiding box <NUM> is controlled to return to a horizontal position, so that the coiled tape <NUM> from the material guiding roller group <NUM> can enter into the next station easily. It is understood that, if some other angle is required by the next station to receive the coiled tape, the material guiding box <NUM> may not return to the horizontal position, but turns to the required angle.

In the embodiment, a central line between the first picking plate <NUM> and the second picking plate <NUM> coincides with a central line O of the material guiding roller group <NUM>. As shown in <FIG>, for the gripping assembly in the "scissor" structure, the first opening-closing driving component <NUM> and the second opening-closing driving component <NUM> may be arranged symmetrically on two sides of the gripping assembly. As shown in <FIG>, for each of the first opening-closing driving component <NUM> and the second opening-closing driving component <NUM>, one end is connected to the material guiding box <NUM>, and an extensible pole at the other end is connected to a corresponding picking plate. The first opening-closing driving components <NUM> and the second opening-closing driving component <NUM> have consistent movement, so that the central line of the first picking plate <NUM> and the second picking plate <NUM> always coincides with the central line O of the material guiding roller group <NUM>. In this way, the extending end <NUM> can enter into the material guiding roller group <NUM> once it enters the gripping assembly. Apparently, the coincidence of the two central lines helps the coiled tape <NUM> to enter into the material guiding group <NUM>. It is understood that, an angular deviation between the two central lines is acceptable.

In addition, the material guiding box <NUM> is installed on the sliding platform <NUM>. The sliding platform <NUM> is installed on the base <NUM>, and can slide relative to the base <NUM>, so as to be close to or away from the coiled tape <NUM> along a radial direction of the coiled tape <NUM>. Therefore, the sliding platform <NUM> drives the material guiding box <NUM> and the gripping assembly on the sliding platform <NUM> to be close to or away from the coiled tape <NUM>. It is noted that, the diameter of the reel <NUM> varies, and the radial dimension of the reel <NUM> wound with the coiled tape <NUM> also varies. The sliding platform <NUM> is configured to adjust a distance between the gripping assembly and the reel <NUM> based on an actual dimension of the reel <NUM> wound with the coiled tape <NUM>, so that the gripping assembly can easily receive the extending end <NUM> of the coiled tape <NUM> after the pitching degree and the opening angle are adjusted.

In the above method, when the location of the extending end <NUM> of the coiled tape <NUM> is obtained, a desired distance between the sliding platform <NUM> and the reel <NUM>, the pitch angle of the material guiding box <NUM> and the gripping assembly, and an opening angle of the gripping assembly can be calculated based on parameters of an outfeeding angle, a diameter of the reel <NUM>, or the like. Therefore, the coiled tape <NUM> is guided to the material guiding machine automatically, thereby realizing intelligent operation without manual adjustment.

It can be seen from <FIG> or <FIG> that, the sliding platform <NUM> moves close to the reel <NUM> to grip the extending end <NUM> of the coiled tape <NUM>. Then the sliding platform <NUM> moves away from the coiled tape <NUM>, so that the extending end <NUM> of the coiled tape <NUM> is smoothly changed to a direction consistent with the central line O, and then is driven to the next station by the material guiding roller group <NUM>.

The material guiding portion, which is configured to receive the extending end <NUM> of the coiled tape <NUM> and guide the extending end <NUM> into the material guiding roller group <NUM>, is not limited to the gripping assembly as described above, but may be in other structures. Reference is made to <FIG>. <FIG> is a schematic structural diagram of a coiled tape material guiding machine according to a second embodiment of the present disclosure, showing that a coiled tape is guided from a position above the coiled tape material guiding machine. <FIG> is a schematic view showing that a coiled tape is guided from a position below the coiled tape material guiding machine according to <FIG>.

In the embodiment, the material guiding portion includes a guiding plate <NUM>. A pitch driving device (not shown in the figure) may be provided to adjust the pitch angle of the guiding plate <NUM> relative to a base <NUM> to receive a coiled tape <NUM>, such that the coiled tape <NUM> is guided into a material guiding roller group <NUM> along an upper surface or a lower surface of the guiding plate <NUM>.

Similar to the above embodiment, a material guiding box <NUM> for installing the material guiding roller group <NUM> and a sliding platform <NUM> slidably connected to the base <NUM> are also provided in the coiled tape material guiding machine according to this embodiment. The material guiding box <NUM> is installed on the sliding platform <NUM>. Functions of the material guiding box <NUM> and the sliding platform <NUM> in this embodiment are similar to those in the above embodiment, which are not described again herein for simplicity.

The guiding plate <NUM> is in cooperation with a baseplate <NUM> in an embodiment. As shown in <FIG>, the baseplate <NUM> is fixed in the material guiding box <NUM>, in a fixed position relative to the material guiding roller group <NUM>. The baseplate <NUM> and the guiding plate <NUM> are both in a triangular shape. Bottoms of the baseplate <NUM> and the guiding plate <NUM> are hinged together. The baseplate <NUM> and the guiding plate <NUM> each have an upper guiding surface and a lower guiding surface. When a material is guided from above, as shown in <FIG>, the guiding plate <NUM> is inclined upward under the drive of the pitch driving device, so that an inclination angle of the upper guiding surface of the guiding plate <NUM> is almost the same as an inclination angle of the extending end <NUM>. The upper guiding surface and the lower guiding surface of the baseplate <NUM> are symmetrically arranged about a central line O of the material guiding roller group <NUM>. The upper guiding surface of the guiding plate <NUM> cooperates with the upper guiding surface of the baseplate <NUM>, to form a guiding slope in a gentle gradient, so that the extending end <NUM> of the coiled tape <NUM> is easily guided into the material guiding roller group <NUM> along the guiding slope.

Similarly, when the material is guided from below, as shown in <FIG>, the guiding plate <NUM> is inclined downward. The lower guiding surface of the guiding plate <NUM> cooperates with the lower guiding surface of the baseplate <NUM> to form a guiding slope in a gentle gradient.

In the case of using the guiding plate <NUM>, rollers may be provided on upside and downside of the guiding plate <NUM>, to facilitate the movement of the extending end <NUM> of the coiled tape <NUM> along the guiding slope to the material guiding roller group <NUM>, avoiding the instability caused by the unilateral guiding. Compared with this embodiment, the guiding realized by the gripping assembly in the above embodiment is more reliable, and has a wide range of application.
