Description

Non-stop taping device for connecting transferring plate

The present invention relates to a taping device for connecting a plurality of conveying plates which are attached in a line on a conveyor and running at a constant speed with a tape, and more particularly, a conveying plate joining which can perform non-stop taping without changing the speed of the conveying plate. It relates to a negative non-stop taping device.

Among the numerous equipment used in industrial sites, equipment that continuously transfers a plate or sheet of a predetermined size cut in advance using a conveyor, and prints the desired contents on the plate or sheet. For example, a rectangular metal plate having a certain thickness is transferred in a line, and a repeated logo or pattern is printed on the upper surface of the metal plate. In the automotive industry, a model of a vehicle or a logo of a vehicle manufacturer is printed on an aluminum plate, and then the printed content is obtained and attached to the vehicle.

In order to print the same contents on a large number of plates, printing is performed using a printing device located above the transfer path of the plates (regardless of the printing method). In order to perform printing at the exact point of each plate, the precision of the position of the transfer plate relative to the printing device is important. If the conveying plate is skewed at an angle with respect to the conveying direction, the printing of the sheet is skewed.

By the way, in the conventional plate material transfer equipment, while the plate material is transferred, the gap between the adjacent plate material in front and back is widened, or the plate material partially overlaps. This phenomenon causes difficulty in precise printing. Separate equipment is required that prevents the plates transferred in a row from spreading or overlapping during transfer.

Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

Basically, the non-stop taping device for the connecting portion of the conveying plate of the present invention prevents relative movement of the adjacent plate by attaching the connecting portion of the conveying plate with a tape. In particular, when taping, the transfer speed of the plate material can be maintained as it is without reducing or stopping it, so that productivity does not decrease.

1 is a perspective view showing the entire structure of a non-stop taping device 10 for connecting a transfer plate member according to an embodiment of the present invention, and FIG. 2 is a cut-away perspective view showing a part of the taping device separately. In addition, FIG. 3 is a view showing a view of the taping device of FIG. 1 from a different angle, and FIG. 4 is a view for explaining the configuration of the taping unit 50 shown in FIG. 1.

As shown, the taping device 10 according to the present embodiment includes a conveyor 12, a frame 20, an X-direction driving part 30, a Y-direction driving part 40, and a taping part 50.

The conveyor 12 provides a horizontal support surface 12a by conveying a plurality of plate members 100 in a line at a constant speed. The support surface 12a horizontally supports the plate material 100 to be transferred. In addition, a transfer guide 14 is provided on the support surface 12a. The transfer guide 14 guides the linear movement of the plate material 100.

The plate members 100 are all square plates having the same size and are connected in a line in the front and rear direction and travel at constant speed in a connected state. The plate material 100 may be an aluminum sheet. The "connected state" means a state in which the cross-sections of the adjacent plate members are in contact with each other in the conveying direction without opening. In addition, the connecting portion or the connecting portion is a portion in which the adjacent plate members are in contact with each other in the conveying direction.

The plate member 100 travels at a constant speed above the conveyor 12 and passes through the lower portion of the taping portion 50. The taping part 50 serves to fix the adjacent plate materials to each other by attaching the tape 79 to the junction part of the plate material 100 passing through the lower portion thereof. This will be described later.

The tape 79 is attached only to the central portion of the junction because it is only necessary to connect adjacent plates back and forth. In other words, it is not necessary to tap to both ends in the width direction orthogonal to the conveying direction of the plate material 100.

The frame 20 is mounted on the top of the conveyor 12 and supports the X-direction driving part 30, the Y-direction driving part 40, and the taping part 50. The structure of the frame can vary as long as it can play this role.

The X-direction driving unit 30 is mounted on the lower portion of the frame 20 and outputs a driving force in the X direction parallel to the conveying direction of the plate material 100. The X direction is a direction parallel to the conveying direction of the plate material 100, and the Y direction is a direction orthogonal to the X direction.

The X-direction driving unit 30 includes a fixed plate 31, a first rail 32, a first lead screw 33, and a first motor 35. The fixing plate 31 is a plate-like member having a predetermined thickness and is horizontally fixed to the upper side of the frame 20 as shown in FIG. 3. Two of the first rails 32 are fixed parallel to both sides of the bottom surface of the fixing plate 31 and support the Y-direction driving part 40 so as to reciprocate.

In addition, the first lead screw 33 is axially rotated by the first motor 35 with both ends supported by the bearing 36. It goes without saying that the first lead screw 33 is parallel to the first rail 32. The first motor 35 is a two-way motor and rotates the first lead screw 33 in both directions. In addition, a reciprocating block 37 is mounted on the first lead screw 33.

The reciprocating block 37 is fixed to the upper surface of the driven plate 41 while being engaged with the first lead screw 33, and when the first lead screw 33 rotates, the driven plate 41 is moved in the X direction. Make it reciprocate. As a result, the driving of the first motor 35 enables the Y-direction driving unit 40 and the taping unit 50 to reciprocate in the X direction.

The Y-direction driving unit 40 receives power from the X-direction driving unit 30, reciprocates in the X direction, and outputs a driving force in the Y direction orthogonal to the X direction.

The Y-direction driving part 40 has an upper slider 42, a driven plate 41, a second rail 43, a second lead screw 45, a reciprocating block 48, and a second motor 44.

The upper slider 42 is a part supported by the first rail 32 so as to be slidably moved, and slides along the first rail 32 by the operation of the first motor 35. In addition, the upper slider 42 also serves to bear the load of the Y-direction driving portion 40 and the taping portion 50.

The driven plate 41 is a square plate fixed to the lower portion of the upper slider 42 and has a pair of second rails 43 on the bottom surface. The second rail 43 extends in a direction orthogonal to the first rail 32 to guide the reciprocating motion of the taping portion 50 in the Y direction.

The second lead screws 45 are installed side by side between the second rails 43 and are capable of axial rotation in both directions by the second motor 44. Both ends of the second lead screw 45 are supported by bearings 46. In addition, a reciprocating block 48 is engaged with the second lead screw 45. The reciprocating block 48 is coupled to the upper surface of the traveling carrier 61 while being engaged with the second lead screw 45. It goes without saying that the traveling carrier 61 reciprocates according to the axial rotation of the second lead screw 45. The second motor 44 axially rotates the second lead screw 45 by outputting a rotational force while being fixed to the driven plate 41.

Meanwhile, a pressing part 51 is provided at one end of the driven plate 41, that is, an end opposite to the end where the second motor 44 is installed. The pressing part 51, as shown in FIGS. 7 and 8, serves to press and fix the plate 100 while taping the connection part is in progress. In other words, the plate material 100 to which the tape 79 is attached is held and fixed so as not to follow the taping portion 50.

The pressing portion 51 has a vertical fixing plate 51a, a pressing actuator 51g, a square frame 51b, and a friction member 51d. The vertical fixing plate 51a is a plate-like member fixed to the end of the driven plate 41 and extending vertically downward, and has a pressing actuator 51g at the lower end.

The pressing actuator (51g) is vertically mounted on the lower end of the vertical fixing plate (51a) and moves the square frame (51b) up and down. The pressing actuator 51g lowers the square frame 51b while taping is in progress and raises the square frame 51b for the rest of the time so that it does not come into contact with the plate material 100.

The rectangular frame 51b is a vertically erected rectangular frame, and provides a space portion 51c having a volume capable of accommodating the roller actuator 81 and the roller 83. This square frame (51b) is located in front of the roller actuator, and the moment the taping portion (50) reaches the upper portion of the junction of the plate material, it descends at the same time to press and support the junction portion of the plate material.

The friction member 51d is a plate-like member made of rubber or soft silicone, and applies a frictional force to the plate material in contact with the upper surface of the plate material 100 so that the plate material does not come off from the lower part during taping. The friction member 51d is replaceable.

The taping part 50 receives power from the Y-direction driving part 40 and is capable of simultaneously moving in the X and Y directions from the top of the plate 100, and the connection part while following the connection part of the plate 100 during transfer It serves to attach the tape 79 to the.

The taping part 50 includes a lower slider 47, a traveling carrier 61, a lifting actuator 63, a lifting plate 65, a support shaft 73, a tape guider 77, a sensor 78, and a tension roll. (75), an extension bracket (69), a cutter actuator (85), and includes a roller actuator (81).

The lower slider 47 is a member supported by the second rail 43 so as to be slidable. The lower slider 47 slides along the second rail 43 by the operation of the second motor 44 and reciprocates the taping portion 50 in the Y direction.

The traveling carrier 61 is a structure that is fixed to the lower slider 47 and provides a supporting force, and includes a lifting actuator 63 on one side. The lifting actuator 63 is mounted vertically and moves the lifting plate 65 up and down. In order to guide the lifting movement of the lifting plate 65, the vertical rail 62 is fixed to the lower part of the lifting actuator 63.

The lifting plate 65 is a plate-like member having a predetermined thickness and has a reel support bracket 66 on one side. The reel support bracket 66 is a plate-like member bolted to the side of the lifting plate 65 and has a horizontal support shaft 73. The support shaft 73 extends in a horizontal direction and rotatably supports the tape reel 71. A tape 79 to be adhered to the plate material 100 is wound around the tape reel 71. The tape 79 has a certain width, is drawn out from the tape reel 71 and adhered to the plate.

An extension bracket 69 is fixed to the opposite end of the reel support bracket 66. The cutter actuator 85 and the roller actuator 81 are supported on the extension bracket 69.

The cutter actuator 85 moves the blade fixing head 86 up and down. The blade fixing head 86 supports the blade 87 vertically. Eventually, the blade 87 moves up and down by the cutter actuator 85. The blade 87 serves to cut the tape 79 after taping is completed, and a description thereof will be described later.

The roller actuator 81 raises and lowers the roller holder 81a. In addition, the roller 83 is supported on the roller holder 81a to enable rolling movement through the roller shaft 83a. The roller 83 runs on the upper portion of the tape 79 and serves to bring the tape into close contact with the joint portion of the plate material 100.

In addition, a tape guide 77 is located at the lower end of the lifting plate 65. As shown in FIG. 7, the tape guider 77 contacts the upper surface of the plate 100 when the lifting plate 65 reaches the bottom dead center, and guides the tape supplied from the tape reel to the junction of the plate. Plays a role. To this end, an inclined surface 77a is formed on the upper surface of the tape guider 77. The inclined surface 77a is a guide surface that guides the tape 79 downward.

In addition, a sensor 78 is located on one side of the bottom of the tape guider 77. The sensor 78 senses the boundary line of the plate member 100 in a connected state, and makes the boundary line of the adjacent plate member 100 located at the center of the width direction of the tape 79. The X-direction driving unit 30 precisely controls the X-direction position of the taping unit 50 based on the information detected by the sensor 78.

The tension roll 75 is installed between the tape reel 71 and the tape guide 77, and guides the tape 79 toward the inclined surface 77a while adjusting the tension of the tape 79.

5 to 10 are views for explaining the operation of the non-stop taping device for connecting a transfer plate according to an embodiment of the present invention.

5 is a state in which both the lifting plate 65 and the square frame 51b are raised, and the taping part 50 and the pressing part 51 are facing the point to be taped. At this time, both the roller actuator 81 and the cutter actuator 85 are also waiting at the top dead center.

When the taping part 50 and the pressing part 51 reach the vertical upper part of the plate joint (running at a constant speed), the traveling carrier 61 is moved in the direction of the arrow a, and the roller actuator 81 and the roller 83 Is accommodated in the space portion 51c of the square frame 51b. In the meantime, it goes without saying that the X-direction driving unit 30 and the Y-direction driving unit 40 also operate without a break.

As shown in Fig. 6, if the roller actuator 81 is inserted into the space 51c, the lifting plate 65 and the square frame 51b are simultaneously lowered as they are. While the lifting plate 65 is descending, the X-direction driving unit finely adjusts the position of the tape guider 77 in the X-direction according to the sensing information of the sensor 78.

Through the above process, the tape guider 77 is positioned on the boundary line of the plate material 100, and the tip of the tape 79 drawn out from the inclined surface 77a of the tape guider 77 is temporarily adhered to the plate material 100. . The tape drawn out from the inclined surface 77a is a tape between the blade 87 and the tape guider 77. Since the blade 87 is spaced apart from the tape guider 77, after cutting the tape 79, in front of the tape guider 77, a length corresponding to the distance between the tape guider 77 and the blade 87 The tape will come out.

In addition, at this time, the friction member 51d is also fixed by pressing the boundary line between the plate members 100, that is, the connection portion downward.

In this state, the traveling carrier 61 is moved in the direction of the arrow c in FIG. 8 and the roller 83 is lowered. The tip of the tape 79 that is temporarily bonded is pressed by the roller 83 and is completely fixed to the plate 100. In addition, the blade fixing head 86 is also lowered at this time. Even if the blade fixing head 86 descends, the blade 87 is spaced apart from the tape 79.

Subsequently, the taping part 50 is moved in the direction of the arrow e in FIG. 9. As the taping part 50 moves, the tape 79 wound on the tape reel 71 is released and passed through the tension roll 75 and the tape guider 77 to be adhered to the plate 100, and the tape 79 The roller 83 which rolls along the line completely adheres the tape 79 to the joint portion of the plate material 100.

When the movement of the taping part 50 in the direction of the arrow e is completed, the lifting plate 65 is raised. At this time, the blade 87 and the roller 83 maintain the lowered state. The reason why the blade 87 is not raised immediately is to cut the tape 79. When the lifting plate 65 rises, the height of the tape 79 hanging on the tape guider 77 increases, and the tape meets the blade 87 and is cut.

When the cutting of the tape is completed, as shown in FIG. 10, the blade 87 and the roller 83 are raised, and the taping part 50 is transferred in the direction of arrow g. As described above, this taping operation proceeds simultaneously with the movement of the plate member 100. That is, the taping part 50 performs taping while moving in the X direction at the same speed as the plate material 100.

11 is a view for explaining a modified example of the roller shown in FIG. 4.

Referring to FIG. 11, it can be seen that the friction coating 84 is filled on the outer peripheral surface of the roller 83. The friction coating 84 is a band-shaped member made of rubber or silicone having elasticity, and when the roller 83 presses the joint portion of the plate 100 downward, it is in a direction in which the plates are in close contact with each other (in the direction of the arrow m). Support. By the action of the friction coating 84, the plate 100 can maintain a tighter contact state during the taping process.

The friction coating 84 is composed of a first friction coating 84a and a second friction coating 84b. The first and second friction coats 84a and 84b are made of the same material and cover the outer peripheral surface of the roller 83 by half. Accordingly, the first friction coating 84a comes into contact with the left plate 100 in the drawing, and the second friction coating 84b comes into contact with the right plate 100 in the drawing.

The first and second friction coatings 84a and 84b are composed of a main body 84c that is closely fixed to the outer circumferential surface of the roller 83, and a plurality of ring-shaped inclined projections 84d integrally formed on the outer circumferential surface of the main body 84c. The inclined projection 84d takes a shape inclined with respect to the main body 84c by a predetermined angle θ. The angle θ may be 45 degrees to 60 degrees.

Since the inclined protrusion 84d is inclined at the above-described angle, the vertical load applied to the roller 83 acts in the direction of the arrow p, and a partial force of the force acting in the direction of the arrow p moves the plate material 100 on both sides in the direction of the arrow m. It works to bring you closer. As described above, by wrapping the roller 83 with the friction coating 84, the plate 100 can be more closely contacted during taping.

As described above, the present invention has been described in detail through specific embodiments, but the present invention is not limited to the above embodiments, and various modifications are possible by those of ordinary skill within the scope of the technical idea of the present invention.
