Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an apparatus for pasting a sheet-like material such as a cover paper or a label to the outer surface of a paper cylinder or other cylindrical body.

[Prior art]

Recently, paper cylinders made by winding kraft paper in multiple layers or
Paper cans, which have a bottom and a lid attached to a paper tube formed by spirally winding cardboard, are lightweight, highly moisture-proof, inexpensive, and easy to dispose of when they become obsolete. It tends to be preferred for these reasons. It is requested that various types of cover paper and labels be attached to the outer surface of paper cans. 6 In general, the attachment of cover paper, etc. to the outer surface of paper cans is carried out on paper tubes, that is, cylindrical bodies. It is carried out in the state of Conventionally, the method for attaching cover paper to the outer surface of a paper tube is as follows: (1) Glue is applied to the outer surface of a rotating paper tube, the cover paper is fed toward the rotating paper tube, and the cover paper is attached to the outer surface of the paper tube. (2) A method in which glue is applied to one side of the cover paper, the cover paper is conveyed toward a rotating paper cylinder at a fixed position, and the cover paper is pressed against the outer surface of the paper cylinder. be. (3) In the past, starch glue was used as the glue for attaching the cover paper to the outer surface of the paper tube.

[Technical problem to be solved]

The method (1) above has the following problems in combination with the use of starchy glue. In other words, starch paste becomes a sol when it contains moisture, and can be applied to the outer surface of the paper cylinder.
Adhesion occurs when water evaporates from the sol state, so
It is necessary to press the cover paper against the outer surface of the paper cylinder while it is in a sol state. However, in method (1), the cover paper is suddenly brought into contact with the glue and pressed against the paper tube, so water from the glue permeates into the cover paper when the cover paper is pressed, causing the cover paper to soften and stretch at the same time. Avoid wrinkles that may occur, air that may enter between the cover paper and paper tube, which may cause irregular blisters, and wrinkles that may remain even after the glue dries, resulting in poor finish on the paper tube. I can't. In addition, in method (2), after gluing is applied to the cover paper and after the elongation of the cover paper due to moisture penetration has completely stopped, that is, after the paper has been killed, the cover paper is pressed against the outer surface of the paper cylinder. This makes it possible to prevent wrinkles from forming. However, in order to apply glue to the cover paper and transport it to the rotating paper tube, in order to simplify the control, the conveying means must be continuously rotated to apply glue to the cover sheet being conveyed, and the paper tube should be rotated as it is. Normally, it is transported towards. For this reason, in conventional machines, gluing is done to kill the paper later, for example, with a diameter of 54 mm.
The length of the cover paper attached to the 0mm paper tube is 1700mm.
However, this required a transport distance of 10M for paper killing, which made the length of the device unreasonably long, creating a problem in terms of installation space. Furthermore, it is difficult for conventional apparatuses for pasting sheet-like objects onto cylindrical bodies to accommodate various diameters of cylindrical bodies. In view of the above-mentioned problems, the present invention has been made in particular to allow sheet-like materials such as cover paper and labels to be placed on the outer surface of a cylindrical body without causing wrinkles.
It is an object of the present invention to provide a device for pasting sheet-like materials onto the outer surface of a cylindrical body, which can be pasted with a good finish. Furthermore, even when the sheet-like object is a cover paper, gluing can minimize the subsequent conveyance distance of the cover paper, and therefore, it is possible to reduce the size of the apparatus by attaching the sheet to the outer surface of the cylindrical body. The purpose of the present invention is to provide a device for pasting objects. Another object of the present invention is to provide an apparatus for pasting sheet-like materials onto the outer surface of a cylindrical body that can easily accommodate various diameters of the cylindrical body.

[Means to solve the problem]

The moving means is operated to press the roll brush against the outer surface of the cylindrical body.

[Effect]

In the automatic gluing machine, gluing is applied to one side of a sheet-like object of a predetermined size. The H-marked sheet-like material is conveyed in a spread state by the conveying means toward the cylindrical body being rotated by the cylindrical body rotating means. When the starting end of the sheet-like material reaches a predetermined position on the cylindrical body, the temporary pasting means preliminarily presses the starting end of the sheet-like material against the outer surface of the cylindrical body, thereby temporarily pasting the sheet-like material on the cylindrical body. . Then, the temporarily pasted sheet-like material is moved by the rotation of the cylindrical body, and is then completely adhered to the outer surface of the cylindrical body by the final pasting means. Before that, between the temporary pasting means and the actual pasting means, the roll brush of the air bleed means moves the outer surface of the cylindrical body in a direction opposite to the conveying direction of the sheet-like object at a peripheral surface speed higher than that of the cylindrical body. Rub with it. Therefore, air that has entered between the sheet-like material and the outer surface of the cylindrical body is completely discharged. As a result, the sheet-like material is adhered to the tibia on the outer surface of the cylindrical body without wrinkles. If the sheet-like object is a paper cover and the automatic gluing machine uses glue as the glue, after gluing the sheet-like object, as soon as the glue has cooled to a predetermined gelling temperature, the sheet-like object will be removed. can be attached by pressing it to the outer surface of the cylindrical body. The cylindrical body rotating means and the main pasting means are arranged opposite to a drive roller which is rotated at a fixed position, are rotated synchronously with the drive roller by a transmission means, and are rotated with respect to the drive roller by a moving means. A press that is supported so as to be movable near and far, allows a part of the cylindrical body to be inserted between the drive roller in a spaced state, and clamps the part of the cylindrical body between the drive roller and the drive roller in a state that they are brought close to each other. In the case of a roller, and a cylindrical support roller that supports the outer surface of the cylindrical body on the opposite side of the pressing point of the drive roller and press roller with respect to the center of the clamped cylindrical body, the circular movement is made by opening and closing the press roller.

【Example】

Next, an embodiment of the present invention will be described based on the drawings.The embodiment shown in FIG. 0 is an embodiment in which the cylindrical body is a paper tube and the sheet-like object is a cover paper. The apparatus for pasting a sheet-like object on the outer surface of a cylindrical body according to the present invention includes:
As shown in FIG. 1, the basic configuration of the automatic gluing machine includes a machine a, a conveying means b, a paper tube rotating means c, a temporary pasting means d, an air bleed means e, and an actual pasting means f. In addition, in a preferred embodiment of this invention, as described later and shown in the drawings,
The paper cylinder rotating means C and the book pasting means f are composed of almost the same elements. In other words, one structure serves as both means. Each of these components will be explained in detail in turn. Automatic gluing lla This automatic gluing machine consists of a glue tank, glue supply roller, doctor,
It consists of an adhesion roller, a cover paper conveyance belt, etc., and the adhesive roller applies glue to one side of the cover paper FP, which is conveyed sheet by sheet at a predetermined speed from a known paper feeding device (not shown). itself is known. However, the use of an automatic gluing machine using glue as the glue and a gluing machine for pasting the cover paper to the outer surface of the paper tube is a new and original element of this invention. Therefore, this automatic gluing machine is equipped with a heater that heats the glue to a required temperature in order to keep the glue in the glue tank in a sol state at all times. The conveying means at the bottom conveys the cover paper FP glued by the automatic gluing Ila in a spread state toward a paper tube supported while being rotated by the paper tube rotating means C in the subsequent stage. , belt conveyors or chain conveyors are used. This conveying means may be shared by extending the cover sheet conveying belt used in automatic gluing machine a. This conveying means is for conveying the glued cover paper FP to the paper tube rotating means C, but it is carried out immediately before or after the glue attached to the cover paper starts to gel during conveyance. In this case, the conveyance length or conveyance speed is set so that the starting end of the cover paper FP reaches the starting point of adhesion of the paper tube in the paper tube rotating means. Glue normally becomes a sol at 55±5'C, and at 40°C.
It changes to a gel state at around °C. Therefore, the length of the conveying means (for gluing, the distance from the position to the starting point of pasting onto the paper cylinder) depends on the environmental temperature at the installation position of the sheet-like material pasting device to the outer surface of the cylinder. That is, the glue solidifies and adheres when cooled, but the cooling rate is naturally faster in forced cooling than in natural cooling, so the conveyance distance can be further shortened. There is also no need for paper killing, as is the case with conventional starchy glues. Therefore, the distance required for transporting the cover sheet can be significantly shortened compared to the conventional device. The paper tube rotating means C is a means for rotating a cylindrical paper tube without a bottom around an axis in a fixed position. There are various possible structures 0
The paper tube may be pressed from the outside with a roller or the like at three points on opposite sides of the center of the tube. Because of this, the strength is not large enough and the roundness is also imperfect. Therefore, when applying cover paper to such a paper tube by pressing it with a press roller from only one side of the outer surface, the paper tube may become distorted, and the distortion may cause the space between the cover paper and the paper tube to become distorted. There is a risk of air getting inside or incomplete adhesion. Therefore, in order to prevent distortion caused by such a one-sided press roller, the paper Il! It is desirable to press the attachment point of the cover paper FP from both the inside and outside of the JD. In this case, a problem arises in terms of structure and installation between the means for rotating the paper cylinder and the means for pressing and pasting the cover paper against the outer surface of the paper cylinder from the inside and outside. In this invention, in order to solve the above-mentioned problem, a common structure is used as both the rotating means and the adhering means (hereinafter referred to as rotating adhering means) as follows. That is, the rotary pasting means cf has a drive roller 1 and a press roller 2, each having a length approximately equal to the length of the paper tube, disposed oppositely on the extension of the conveyance path of the conveyance means, and the rotational movement of the drive roller 1 is transferred to the transmission means. 3 for transmitting the information to the press roller 2, and a moving means 4 for attaching the press roller 2 so as to be able to move near and far with respect to the drive roller l. A support roller 5 is placed on the opposite side of the pressing point of both rollers 1 and 2 with respect to a vertical line passing through the center of the paper tube that is holding the paper tube.
It is configured by arranging. The drive roller 1 is rotated in a predetermined direction by a power source common to the conveyance means at a circumferential speed that matches the conveyance speed of the drive roller 1. The transmission means 3 fixes gears 31 and 32 on the shafts of the drive roller 1 and press roller 2, respectively, and rotates one end of a lever 35 on a shaft 34 that supports a gear 33 that meshes with the gear 31 of the drive roller 1. A frame that supports the press roller 2 with the other end of the lever 35 connected to the lever 35 via an elastic member 37 such as a coil spring. 38, and the gear 36 is attached so as to mesh with the gear 32 of the press roller 2. As a result, the press roller 2 is rotated in the opposite direction to the drive roller 1. However, the transmission means 3 is not limited to one that uses only gears, and as illustrated in FIG. A belt 34a + 35
A may be multiplied by a and passed. Both ends of the shaft 2a of the press roller 2 are connected to a moving means 4 such as a solenoid or a piston of an air cylinder.
is between drive roller 1 and M. When the moving means is driven, press roller 2 is moved and pressed in the direction of drive roller 1 as shown in FIG. 4, and the drive is stopped. When the press roller 2 is moved to the second
It is designed to be retracted and returned to the position shown in the figure. Thus, while the press roller 2 is in the retracted position, the paper tube is inserted into the rotating and pasting position so that the press roller 2 enters the paper tube and rests on the support roller 5. It can also be removed from that position. When the moving means 4 is driven while the paper tube is in the rotating and pasting position, the paper tube is strongly clamped between the rollers 1 and 2. At this time, the support roller 5 is slidably supported by a panel 6 so that the support roller 5 can come into contact with and hold the outer surface of the paper tube regardless of the diameter of the paper tube. It is attached to the tip of a bar 7, and the bar 7 can be fixed in any position with a bolt 9a inserted into a horizontally long hole 8 provided in the panel 6 and a nut 9b screwed into the bolt 9a. . The maximum diameter is the diameter of the paper tube Dmax that can be supported when the support roller 5 is in the position shown in FIG. 2, and the minimum diameter is the diameter of the paper tube Dmin that can be supported when the support roller 5 is in the position shown by the chain line in FIG. Then, when there are indicators provided on the bar 7 corresponding to the maximum diameter and minimum diameter, a scale corresponding to the indicator is provided on the panel 6, and each scale has a value representing the diameter of the paper tube. Furthermore, between the maximum scale and the minimum scale, scales and values corresponding to various diameters of the paper cylinder are written as necessary. In this way, after positioning the bar 7 in advance in accordance with the diameter of the paper cylinder to which the cover paper is to be attached, the paper cylinder is moved to the roller 1,
2, the paper tube can be inserted quickly in a stable state, that is, without damaging the paper tube. Between the rear end of the conveying means and the pressing point of both rollers 1.2, the temporary pasting means d and the air bleed means e are arranged in this order along the moving direction of the cover paper FP. It is a provision. Temporary pasting means d This temporary pasting means d temporarily pastes at least the starting end of the cover paper FP conveyed by the conveying means S onto the outer surface of the paper tube which is being rotated while being held by the rotary pasting means cf. It is. That is, the cover paper FP is completely stuck to the paper tube by the pressure of both rollers 1.2 that constitute the book sticking means f, but the cover paper FP is stuck between the rollers 1.2 of the book sticking means f. In order to introduce at least the beginning of the paper f!, at least the beginning of the paper f! A pasting roller 11 is rotatably attached to the tip of a lever 10 that is swingably supported at one end, and a spring and air are used to bias the lever 10 upward. It is configured by providing a cylinder and other biasing means 12. When temporarily pasting only the starting edge of the cover paper onto the paper tube, a detector (not shown) is installed in front of the pasting roller 11 to detect and output the starting edge of the cover paper, and the detection output is based on the detection output. Then, the biasing means 12 raises the pasting roller 11 toward the paper tube only for a predetermined short period of time. The conveying means may be temporarily stopped based on the detection output of the detector, the pasting roller 11 is raised and lowered to temporarily adhere, and the conveying means is operated again as the pasting roller 11 is lowered. In this case, It is possible to improve the accuracy of the pasting position of the starting end. In order to ensure that the starting end of the wrapping paper FP is affixed to the outer surface of the paper tube, the pasting roller 11 always attaches the sheet to the paper tube at the lowest position of the paper tube, regardless of the diameter of the paper tube. It is attached so that it can be positioned according to the diameter of the paper tube so as to press the paper. To explain an example of an S construction for this purpose, the lever 10 is formed by a fixed lever 10a having one end fixed to the panel 6, and a sliding lever 10b slidably connected to the tip of the fixed lever. , a pasting roller 11 is attached to the tip of the sliding lever, and an index provided on the sliding lever 10b indicates that paper 1! When jD is the maximum diameter and the minimum diameter, the corresponding scale is set on the fixed lever 10a.
Moreover, there are scales corresponding to other diameters between these scales, and it is possible to position the pasting roller in advance according to the diameter of the paper cylinder to which the cover paper is to be pasted. . Air bleed means e Finally, the air bleed means e is the shaft 14 of the roll brush 13.
is connected to an elevating means 15 such as an air cinder, and its shaft 14 is connected to a rotating means (not shown) such as a motor, and the elevating means normally rotates the roll brush 13 and connects it to the adhering means cf. The paper tube is held in a position spaced apart from the outer surface of the paper tube, which is held between rollers 1.2. The rotating means is rotated in a direction opposite to the direction of conveyance by the conveying means and at a circumferential speed greater than the circumferential speed of the paper tube. A control circuit (not shown) is connected to the elevating means 15, and the control circuit is configured to control when the starting end of the cover sheet conveyed by the conveying means passes the crimping position of the rotary pasting means cf. A detector (not shown) is connected, and when the detector detects the front end of the cover paper, it outputs an output signal until the end of the cover paper is detected. Based on this output, when the starting end of the cover sheet conveyed by the conveying means is held between the rollers 1 and 2, the elevating means 15 acts to move the brush roller 13 as shown in FIG.
are pressed against the rotating paper tube, so the cover paper FP and paper f! are transported. ! Air that may enter between the outer surface of the iD and the outer surface of the iD is removed before the cover paper is fully attached by the rollers 1 and 2. In this way, after air is removed from the cover paper, both rollers 1 and 2
Since the adhesive is crimped by the machine, there will be no bulging caused by air.Also, even if the conveyance distance from the machine to the rotational application position (crimping point) is short, since glue is used for the adhesive, Since there is no elongation and the temperature of the glue has decreased to the appropriate temperature at the actual pasting position, rollers 1.2
When it is crimped, it is completely adhered without any bulges or wrinkles. In addition, flanges la and 5a are formed at both ends of the rollers 1.5 in order to prevent the paper tubes supported by the rollers from moving in the axial direction of these rollers and coming off. . The operation of the entire process of pasting the cover paper with the above configuration will be explained with reference to FIG. It is moved to a predetermined position and fixed by the positioning means 7.8.9a, 9b, and similarly, the pasting roller 11 of the temporary pasting means d is also moved to a predetermined position by the positioning means 10a, 10b. In the rest state, a part of the peripheral wall of the paper tube is interposed between the drive roller 1 and the press roller 2, which is spaced apart, and the frame 38 and the press roller 2 are housed within the paper tube. Then, a paper tube is loaded, and the paper tube is placed on the support roller 5. Next, turn on the start switch of the drive unit (not shown).
Then, the press roller 2 is moved in the direction of the drive roller 1 by the moving means 4, and the paper tube is moved by those rollers 1.
2, and by the rotation of the drive roller 1, the paper tube is rotated at a predetermined position in a predetermined direction, that is, clockwise in FIG. Also, turn on the start switch
Along with this, the cover paper FP is fed out one by one at predetermined intervals from the paper feeding device to the automatic gluing Ila, and the cover paper is sent onto the conveying means while glue is adhered to one side of the cover paper. Covering paper FP to which glue is attached and conveyed by conveyance means
The starting end of is pressed against the outer surface of the paper tube by the pasting roller 11 of the temporary pasting means d. At this point, the glue on the cover paper has been cooled to around 40°C, which is the gelation starting temperature. Therefore, since the starting end of the cover paper FP is stuck to the paper tube, the continuous conveyance of the cover sheet and the rotation of the paper tube ensure that the cover sheet FP is firmly attached to the rear roller 1 along with the paper tube.
Proceeds between 2. Based on the output of the detector that detects the starting edge of the cover sheet, when it is detected that the starting edge of the cover sheet has passed the pressing point by the roller 1.2, the elevating means 15 of the air bleed means e is driven. Then, the roll brush 13 is pressed against the outer surface of the paper tube and rotated in the opposite direction to the rotating direction of the paper tube to stroke the cover paper FP over its entire width, so that there is a gap between the cover paper and the outer surface of the paper tube. Incoming air is quickly and completely eliminated. Then, with the air removed, the cover paper FP is pressed against the outer surface of the paper tube by a pair of inner and outer rollers 1 and 2. In this way, when the entire length of the cover paper is pasted to the entire circumference of the outer surface of the paper cylinder, the detector of the air bleed means e detects the end of the cover paper and eliminates the detection output. Based on this, the elevating means 15 of the air bleed means returns to its original position, and the rotation of the drive roller 1 of the rotary pasting means cf is stopped, and
The press roller 2 is returned to its original separated position by the moving means 4. In this state, the paper tube to which the cover sheet has been pasted is perturbed in the axial direction and removed from the rotary pasting means cf, that is, from between the rollers 1 and 2. Subsequently, the next paper tube is loaded in the same way as the previous one, and based on the ON operation of the start switch, the operations of paper feeding, gluing, conveyance, temporary pasting, air bleeding, and final pasting are performed in the same manner as described above. Then, the cover paper is attached to the paper tube at the shin. Note that the loading and unloading of the paper tube into the main pasting means may be performed manually, or may be performed using an automatic attachment/detachment device as exemplified in FIG. To roughly explain the configuration of this automatic attachment/detachment device, a plurality of paper tubes are prepared on a ramp 51, and an individual rotor blade is provided on the downstream side of the ramp and is intermittently rotated by a motor 52 or the like. A cylinder 55 is supported by a pair of front and rear support legs 56, and a cylinder 55 is supported by a pair of front and rear support legs 56, and a cylinder 55 is supported by a pair of front and rear support legs 56. A paper cylinder gripper 57 connected to the rodless piston is supported movably in the axial direction of the paper cylinder by a guide rod 58 suspended between the support legs 56. As a result, when the piston moves forward due to the drive of the cylinder 55, the paper tube in the groove 54 is held by the receiver, and the paper tube is loaded between the pair of rollers 1.2, and the sheet-like material is not attached to the outer surface of the paper tube. During pasting, the gripping tool 57 is separated from the paper cylinder and stands by, and when pasting is completed, the gripping tool 57 grips the paper cylinder again, and the piston is retracted to receive the paper cylinder. i14
The paper tube that has been pasted is then stored in a storage box or the like installed adjacent to it by a half turn of the groove. Simultaneously with the return of the trough 54 to its initial position, the rotary blades 53 are again rotated by a predetermined angle, and the next paper tube is replenished and similarly fed between the rollers 1.2. Other Embodiments Although the automatic sizing machine has described and illustrated the preferred embodiment in which the machine uses glue, the above sizing machine, conveyance means,
The configuration of the temporary pasting means, air bleed means, and main pasting means can also be applied to a sheet pasting device that uses general glue, and can also be used for pasting cover paper or labels on cylindrical bodies made of materials other than paper tubes. It can be used for any purpose, and there is no difference in the effect that it can be applied to odd surfaces without wrinkles.

【Effect of the invention】

As described above, the apparatus for pasting sheet-like objects on the outer surface of a cylindrical body according to the present invention is capable of pasting sheet-like objects such as cover paper and labels on the outer surface of a cylindrical body with a good finish and without wrinkles. be able to. Further, according to this invention, since glue is used for the glue, there is no need to kill the paper even when the sheet-like object is cover paper, so gluing can minimize the subsequent conveyance distance of the cover paper. Therefore, it is possible to significantly downsize the device. Furthermore, by using glue, there is no blistering or wrinkling caused by water penetration into the cover paper, and a beautiful finish can be achieved. Further, a part of the peripheral wall of the cylindrical body is sandwiched between a pair of rollers, and the cylindrical body is placed on the support rollers and held.
Moreover, since the temporary pasting means is also constituted by a roller that presses against the lowest position of the circular FJ body, it can easily accommodate various diameters of the cylindrical body.
