Description

Technical Field

[0001] The present invention relates to the technical field of industrial production equipment, and particularly to a string threading device and a label production device. Background Art

[0002] Labels are paper products that can be seen everywhere in daily life and are widely used in fields such as product labels. For example, before containers such as bottles and jars leave the factory, labels need to be hung. A label includes a label paper and an elastic cord connected to the label paper. The elastic cord is put on the bottle mouth of the bottled object to achieve the hanging of the label.

[0003] The connection between the elastic cord and the label paper can be achieved by threading the elastic cord through the hole in the label paper and tying a knot on the elastic cord. Since the semi-finished product of the label paper lacks a connection hole, the existing label production equipment generally chooses to punch holes in the label paper first, and then drives the elastic cord to pass through the connection hole in the label paper. However, in the actual production process, it is difficult for the elastic cord to align with the connection hole, resulting in a low string threading efficiency, and thus a low string-label connection efficiency. Summary of the Invention

[0004] The main object of the present invention is to propose a string threading device and a label production device, aiming to solve the problem of low string-label connection efficiency existing in the existing label production equipment.

[0005] To achieve the above object, a string threading device proposed by the present invention includes a string threading mechanism and a string feeding mechanism for feeding an elastic cord to the string threading mechanism. The string threading mechanism includes a mounting base and a hollow string threading member. The mounting base is provided with a guide cord hole penetrating in the z direction, and a placement groove for the unpunched label paper to extend into and be placed is formed on the mounting base. The guide cord hole is on the moving path of the elastic cord fed by the string feeding device. The hollow string threading member is movably arranged in the guide cord hole. A cutting head capable of punching holes in the label paper is connected to the bottom end of the hollow string threading member. The moving path of the hollow string threading member passes through the placement groove.

[0006] According to some embodiments of the present invention, the string feeding mechanism includes a string feeding assembly and a string feeding shaft for sleeving and installing an elastic cord roll. The string feeding assembly includes two relatively arranged string feeding rollers, and a first clamping groove for the elastic cord to pass through is defined between the two string feeding rollers.

[0007] According to some embodiments of the present invention, the string feeding mechanism further includes a guide cord pipe. One end of the guide cord pipe is arranged corresponding to the first clamping groove, and the other end is connected to the mounting base of the string threading mechanism and is arranged corresponding to the guide cord hole.

[0008] According to some embodiments of the present invention, the string feeding assembly further includes two guide cord members, which are respectively arranged on the incoming cord side and the outgoing cord side of the two string feeding rollers, and the guide cord members are tapered from their incoming cord ends to their outgoing cord ends.

[0009] In addition, the present invention further provides a label production device, which includes a frame, a string threading device as described in any one of the above, and a label supply device for supplying label paper to the string threading device. The label supply device includes a label conveying mechanism and a label collection mechanism for stacking label paper. The label collection mechanism and the string threading device are arranged at intervals in the x direction on the frame. The label conveying mechanism includes a label adsorption part movably arranged in the x direction, and the moving stroke of the label adsorption part passes through the label collection mechanism and the placement groove of the string threading mechanism.

[0010] According to some embodiments of the present invention, it further includes a knotting mechanism. The knotting mechanism includes an xz driving platform and a rope clamping part rotatably arranged on the xz driving platform along an axis extending in the z direction. The rope clamping part is driven by the xz driving platform to move in the x direction and the z direction, and the moving stroke of the rope clamping part passes through the placement groove of the string threading mechanism. The rope clamping part has a second clamping groove for the elastic ropes located above and below the label paper to extend into and be fixed simultaneously.

[0011] According to some embodiments of the present invention, it further includes a rope clamping assembly. The rope clamping assembly is located below the string threading mechanism and corresponds to the wire guiding hole for one end of the elastic rope to pass through the label paper and be clamped and fixed by the rope clamping assembly.

[0012] According to some embodiments of the present invention, it further includes a label clamping mechanism. The label clamping mechanism is arranged on one side of the string threading mechanism facing the knotting mechanism. The label clamping mechanism has a third clamping groove for the label paper to extend into and be fixed. The label clamping mechanism is movably arranged in the y direction, and the moving stroke of the label clamping mechanism passes through the placement groove of the string threading mechanism.

[0013] According to some embodiments of the present invention, the rope clamping part includes two rope clamping members hinged to each other. Each rope clamping member has a groove for the elastic ropes above and below the label paper to be wound and placed, and the groove is arranged near the hinged end of the rope clamping member.

[0014] According to some embodiments of the present invention, the label collection mechanism includes a label stacking seat, and the label stacking seat is movably arranged in the z direction.

[0015] The present invention has at least the following beneficial effects:

[0016] In the present invention, the unpunched label paper is placed in the placement groove of the rope threading mechanism, the elastic rope is driven by the rope feeding device to enter the rope guide hole of the rope threading mechanism, the hollow rope threading member is movably arranged in the rope guide hole, so that the elastic rope enters the hollow rope threading member from the rope guide hole, the bottom end of the hollow rope threading member is connected to a cutting head that can punch holes in the label paper, because the rope guide hole is penetrated on the mounting seat of the rope threading mechanism, the placement groove divides the rope guide hole into two sections, when the hollow rope threading member moves to When the hollow rope threading member moves downward to the placement slot, the cutting head at the bottom end of the hollow rope threading member punches holes in the unpunched label paper, and then the bottom end of the hollow rope threading member passes through the placement slot, so that one end of the hollow rope threading member is connected to the rope guide hole above the placement slot, and the other end is connected to the rope guide hole below the placement slot. At the same time, the rope feeding device drives the elastic rope to move downward along the hollow rope threading member through the hole of the label paper. Finally, the hollow rope threading member moves upward, and the elastic rope does not move, so as to complete the connection between the elastic rope and the label paper. The rope threading mechanism in the present invention combines the punching step and the rope threading step into one step, which, on the one hand, reduces the step of punching holes in the label paper in advance, shortens the rope label connection time, and improves the rope label connection efficiency. On the other hand, because the cutting head at the bottom end of the hollow rope threading member passes through the placement slot after punching holes in the label paper, the elastic rope moves downward along the hollow rope threading member through the connection hole of the label paper without aligning the connection hole, which greatly improves the rope threading efficiency, thereby further improving the rope label connection efficiency.

[0029] The present invention provides a string threading device and a label production device. Figures 1 to 6 This is a specific embodiment of the string threading device and the label production device provided by the present invention.

[0030] As Figure 2 、 Figure 3 and Figure 6 As shown in

[0031] In the present invention, an unperforated label paper is placed in the placement groove 112 of the string threading mechanism 1. An elastic cord is driven by the cord feeding device 2 into the cord guiding hole 111 of the string threading mechanism 1. The hollow string threading member 12 is movably arranged in the cord guiding hole 111, so that the elastic cord enters the hollow string threading member 12 from the cord guiding hole 111. A cutting head 121 capable of perforating the label paper is connected to the bottom end of the hollow string threading member 12. Since the cord guiding hole 111 penetrates through the mounting seat 11 of the string threading mechanism 1, the placement groove 112 divides the cord guiding hole 111 into two sections. When the hollow string threading member 12 moves downward to the placement groove 112, the cutting head 121 at the bottom end of the hollow string threading member 12 perforates the unperforated label paper. Then the bottom end of the hollow string threading member 12 passes through the placement groove 112, so that one end of the hollow string threading member 12 communicates with the cord guiding hole 111 above the placement groove 112, and the other end communicates with the cord guiding hole 111 below the placement groove 112. At the same time, the cord feeding device 2 drives the elastic cord to move downward along the hollow string threading member 12 through the hole of the label paper. Finally, the hollow string threading member 12 moves upward while the elastic cord remains stationary to complete the connection between the elastic cord and the label paper. The string threading mechanism 1 in the present invention combines the perforating step and the string threading step into one step. On the one hand, it reduces the step of perforating the label paper in advance, shortens the connection time of the cord label, and improves the connection efficiency of the cord label. On the other hand, since the cutting head 121 at the bottom end of the hollow string threading member 12 passes through the placement groove 112 after perforating the label paper, the elastic cord moves downward along the hollow string threading member 12 through the connection hole of the label paper without aligning with the connection hole, greatly improving the string threading efficiency, and thus further improving the connection efficiency of the cord label.

[0032] Specifically, the cutting head 121 has a wavy cutting surface, so that when punching, the contact area between the cutting surface of the cutting head 121 and the label paper is smaller and the pressure is greater, thereby making punching easier.

[0033] The specific structure of the rope feeding device 2 is not limited, as long as it can actively feed the elastic rope. For example, in some embodiments, as Figure 2 shown, the rope feeding mechanism includes a rope feeding component 21 and a rope feeding shaft 22 for sleeving and installing the elastic rope roll. The rope feeding component 21 includes two relatively arranged rope feeding rollers 211, and a first clamping groove for the elastic rope to pass through is defined between the two rope feeding rollers 211. With such a setting, since the elastic rope is clamped by the two rope feeding rollers 211, the rotation of the two rope feeding rollers 211 can drive the elastic rope to move into the rope guiding hole 111 of the rope threading mechanism 1, completing the rope feeding step.

[0034] Since the elastic rope is arranged in a roll, the free end of the elastic rope will bend during rope feeding, making it difficult to enter the rope guiding hole 111. Therefore, in some embodiments, as Figure 2 shown, the rope feeding mechanism further includes a rope guiding tube 23. One end of the rope guiding tube 23 is arranged corresponding to the first clamping groove, and the other end is connected to the mounting seat 11 of the rope threading mechanism 1 and is arranged corresponding to the rope guiding hole 111. The elastic rope is driven by the rope feeding rollers 211 to move to the rope guiding tube 23 and enters the rope guiding hole 111 through the rope guiding tube 23. With such a setting, on the one hand, the efficiency of the elastic rope entering the rope guiding hole 111 can be improved through the guidance of the rope guiding tube 23, and on the other hand, the rope guiding tube 23 can be arranged as a bent tube, so that the rope feeding component 21 can be arranged on one side or obliquely above the rope threading mechanism 1, without restricting the rope feeding component 21 to be arranged directly above the rope guiding hole 111.

[0035] Since the free end of the elastic rope is bent, it is difficult for the elastic rope on the elastic rope roll to enter the first clamping groove. Therefore, in some embodiments, as Figure 2 shown, the rope feeding component 21 further includes two rope guiding members 212. The two rope guiding members 212 are respectively arranged on the rope inlet side and the rope outlet side of the two rope feeding rollers 211, and the rope guiding members 212 are tapered from their rope inlet ends to their rope outlet ends. Since the diameter of the rope inlet end of the rope guiding member 212 is larger than that of the rope outlet end, the bent elastic rope can enter the rope guiding member 212 and enter the first clamping groove defined by the two rope feeding rollers 211 through the rope guiding member 212. Then, the elastic rope enters the rope guiding hole 111 through the other rope guiding member 212 under the drive of the rope feeding rollers 211.

[0036] In addition, as Figure 1As shown in the figure, the present invention further provides a label production device 1000, including a frame 200, the string threading device 100, and a label supply device 300 for supplying label paper to the string threading device 100. The label supply device 300 includes a label conveying mechanism 301 and a label collecting mechanism 302 for stacking label paper. The label collecting mechanism 302 and the string threading device 100 are spaced apart in the x direction on the frame 200. The label conveying mechanism 301 includes a label adsorption part 3011 movably arranged in the x direction. The moving stroke of the label adsorption part 3011 passes through the label collecting mechanism 302 and the placement groove 112 of the string threading mechanism 1.

[0037] In the present invention, the label adsorption part 3011 sucks the label paper stacked on the label collecting mechanism 302, then moves in the x direction to the string threading mechanism 1, and places the label paper in the placement groove 112 of the string threading mechanism 1 to achieve label supply.

[0038] Since there are multiple label papers stacked on the label collecting mechanism 302, when the top label paper is conveyed to the string threading device 100, there is a gap between the label adsorption part 3011 and the next label paper, which may cause the label adsorption part 3011 to be unable to suck the label paper. Therefore, the label adsorption part 3011 is movably arranged in the z direction, so that the label adsorption part 3011 can move downward a certain distance to suck the next label paper.

[0039] Since the stacking thickness of the label paper is affected by the moving distance of the label adsorption part 3011 in the z direction, in order to avoid the label adsorption part 3011 colliding with the top surface of the frame 200, it is necessary to limit the moving distance of the label adsorption part 3011 in the z direction, which in turn results in the inability to stack too many label papers. Therefore, in some embodiments, as Figure 1 shown, the label collecting mechanism 302 includes a label stacking seat 3021, and the label stacking seat 3021 is movably arranged in the z direction. With this arrangement, when the top label paper is conveyed to the string threading device 100, the label stacking seat 3021 moves upward a certain distance, so that the label paper can be sucked by the label adsorption part 3011, and the stacking thickness of the label paper is not affected by the moving distance of the label adsorption part 3011 in the z direction, greatly increasing the number of label papers that can be stacked by the label collecting mechanism 302.

[0040] After the elastic cord passes through the connection hole of the label paper, it is necessary to tie a knot in the elastic cord to prevent the elastic cord from detaching from the label paper. Therefore, in some embodiments, as Figure 3 and Figure 6As shown, the label production device 1000 further includes a knotting mechanism 400. The knotting mechanism 400 includes an xz driving platform 401 and a rope clamping part 402 rotatably arranged on the xz driving platform 401 along an axis extending in the z direction. The rope clamping part 402 is driven by the xz driving platform 401 to move in the x direction and the z direction, and the moving stroke of the rope clamping part 402 passes through the placement groove 112 of the rope threading mechanism 1. The rope clamping part 402 has a second clamping groove for the elastic ropes located above and below the label paper to extend into and be fixed at the same time. The rope clamping part 402 of the knotting mechanism 400 moves to the placement groove 112 of the rope threading mechanism 1 under the drive of the xz driving platform 401, and simultaneously clamps the elastic ropes located above and below the label paper. Then, the rope clamping part 402 rotates relative to the xz driving platform 401, so that the elastic rope above the label paper and the elastic rope below the label paper are stretched and wound around the rope clamping part 402. Then, the rope clamping part 402 moves in the x direction, the elastic ropes are separated from the rope clamping part 402, and the elastic ropes located above and below the label paper contract and continue to maintain the mutually wound state to achieve the knotting of the elastic ropes.

[0041] It should be noted that when the rope clamping part 402 clamps the elastic rope for knotting, the elastic rope will be stretched. Since the rope clamping part 402 is located on one side of the rope threading mechanism 1, the elastic rope forms a certain angle with the placement groove 112 of the rope threading mechanism 1. After the elastic rope is knotted, the hollow rope threading member 12 is driven to move downward, and the cutting head 121 at the bottom end of the hollow rope threading member 12 can cut the elastic rope, so that the elastic rope is separated from the rope threading mechanism 1, which is convenient for the rope threading mechanism 1 to connect the next group of label paper and elastic ropes. With this setting, the function of cutting the elastic rope is integrated on the hollow rope threading member 12, eliminating the need to set up additional cutting components, reducing the equipment cost, and reducing the complexity of the equipment structure.

[0042] In order to prevent the elastic rope from detaching from the rope clamping part 402 during the winding process, in some embodiments, as Figure 4 shown, the rope clamping part 402 includes two rope clamping members 4021 hinged to each other. Each rope clamping member 4021 has a groove for the elastic ropes located above and below the label paper to be wound and placed. The groove is arranged near the hinged end of the rope clamping member 4021. With this setting, the free ends of the rope clamping members 4021 first approach each other to clamp the elastic ropes located above and below the label paper. Then, the rope clamping part 402 rotates so that the elastic ropes are wound around the rope clamping members 4021 for one circle. Then, the free ends of the rope clamping members 4021 move away from each other, so that the elastic ropes move in the direction of approaching the hinged end of the rope clamping members 4021 under the action of the contraction force until they enter the groove, so as to prevent the elastic ropes from detaching from the rope clamping members 4021 during the subsequent rotation of the rope clamping part 402.

[0043] After the rope clamping part 402 clamps the elastic ropes above and below the label paper simultaneously, it rotates relative to the xz driving platform 401, so that the elastic ropes at both ends are stretched and wound around the rope clamping part 402. However, if the elastic rope below the label paper lacks fixation, the elastic rope below cannot be stretched. Relying only on the contraction of the elastic rope above will cause the knot to be not firm enough and easy to loosen. Therefore, in some embodiments, such as Figure 3 and Figure 6 shown, the label production device 1000 further includes a rope clamping assembly 500. The rope clamping assembly 500 is located below the rope threading mechanism 1 and is arranged corresponding to the rope guiding hole 111 for one end of the elastic rope to pass through the label paper and be clamped and fixed by the rope clamping assembly 500. By clamping and fixing the elastic rope below the label paper through the rope clamping assembly 500, both ends of the elastic rope can be stretched and wound around the rope clamping part 402. When the elastic rope disengages from the rope clamping part 402, it will contract and continue to maintain the mutually wound state to realize the knotting of the elastic rope.

[0044] Since the space in the placement groove 112 is small, it is difficult for the rope clamping part 402 to extend into the placement groove 112 to clamp the elastic ropes above and below the label paper simultaneously. Therefore, in some embodiments, such as Figure 4 shown, the label production device 1000 further includes a label clamping mechanism 600. The label clamping mechanism 600 is arranged on one side of the rope threading mechanism 1 facing the knotting mechanism 400. The label clamping mechanism 600 has a third clamping groove for the label paper to extend into and be fixed. The label clamping mechanism 600 is movably arranged in the y direction, and the moving stroke of the label clamping mechanism 600 passes through the placement groove 112 of the rope threading mechanism 1. With such an arrangement, by the label clamping mechanism 600 first clamping the label paper and moving in the y direction, on the one hand, the label paper is fixed to avoid affecting the knotting of the elastic rope, and on the other hand, moving the label paper out of the placement groove 112 will make the elastic ropes above and below the label paper approach each other, facilitating the subsequent clamping of the elastic ropes above and below by the rope clamping part 402.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
