Description

Technical Field

[0001] The present disclosure relates to a device having a movable part and a two-handed button for operating the movable part.

Background Art

[0002] Conventionally, for example, in a factory or the like, a device having a movable part that acts on a work object may be used. When an operator performs work on a work object using such a device, there is a risk that the operator's hands or fingers may be caught between the movable part and the work object, between the movable part and the device body, or the like. Therefore, a two-handed button may be provided as a safety mechanism in a device having a movable part. The two-handed button usually has at least two buttons fixed to the device body at a distance from each other, and the movable part of the device operates only while the operator is pressing the buttons with the right hand and the left hand simultaneously. Therefore, it is possible to prevent the hands and fingers from being caught by the movable part. However, while the operator is pressing the two-handed button, both hands of the operator are occupied, so another work cannot be performed in parallel.

[0003] Patent Document 1 discloses a helmet wearing detection device that enables equipment to operate only when a helmet is worn. It describes attaching a device combining a wireless communication device and a contact detection sensor to the chin strap of a helmet, and moving the equipment when contact is detected and stopping the equipment when no contact is detected. However, on the premise of safety first, it is natural to wear a helmet during work. In addition, attaching a device integrating a contact detection sensor and a wireless communication device to the helmet increases the weight, which becomes a burden on the operator. Also, even when the operator feels danger, it is difficult to quickly remove the chin strap and perform an emergency stop. Therefore, it is also insufficient as an emergency stop function.

Patent Document 1

[0005] When workers perform tasks around the moving parts of a device, it is recommended to use a jig to ensure safety. Even when using a jig, as mentioned above, the moving parts must only move while the two-handed push buttons are pressed to prevent hands or fingers from getting caught. However, if the two-handed push buttons are fixed to the device body, workers must release their hands from the jig to press the buttons. This can impair work efficiency. Thus, conventionally, it has been difficult to achieve both work efficiency and safety.

[0006] This disclosure is an invention made in view of the above circumstances, and its main objective is to provide a device having a movable part that acts on an object to be worked on, which can ensure safety while suppressing a decrease in work efficiency. [Means for solving the problem]

[0007] One embodiment of the present disclosure provides a work device comprising: a main body of the device; a movable part disposed on the main body of the device that acts on a work object; and a jig for positioning the work object in a position where the movable part can act, wherein a first push button is disposed on the main body of the device; a second push button is disposed on the jig; and the movable part can move while both the first and second push buttons are pressed. [Effects of the Invention]

[0008] According to this disclosure, it is possible to provide a device that has movable parts that act on an object to be worked on, while suppressing a decrease in work efficiency and ensuring safety. [Brief explanation of the drawing]

[Figure 4] This is a schematic perspective view illustrating the operation using the apparatus of the first embodiment of this disclosure. [Figure 5] These are schematic perspective views and schematic perspective views of a winding core, illustrating an example of the apparatus (winding machine) according to a second embodiment of the present disclosure. [Figure 6] This is a schematic perspective view showing an example of a receiving jig in a second embodiment of the present disclosure. [Figure 7] This is a schematic perspective view illustrating the operation using the apparatus of the second embodiment of this disclosure. [Modes for carrying out the invention]

[0010] Embodiments of this disclosure will be described below with reference to drawings and other figures. However, this disclosure can be implemented in many different ways and should not be interpreted as being limited to the embodiments described below. In addition, in order to make the explanation clearer, the drawings may schematically represent the width, thickness, shape, etc. of each part compared to the actual form, but these are merely examples and should not limit the interpretation of this disclosure. Furthermore, in this specification and each figure, elements similar to those described above with respect to previously shown figures will be denoted by the same reference numerals, and detailed explanations may be omitted as appropriate.

[0011] In this specification, when describing a configuration in which one component is placed on top of another component, unless otherwise specified, the terms "on top" or "below" include both cases: one where the other component is placed directly above or below the component in contact with it, and another where the other component is placed above or below the component via yet another component. Furthermore, when describing a configuration in this specification in which one component is placed on the surface of another component, unless otherwise specified, the terms "on the surface" or "on the surface" include both cases: one where the other component is placed directly above or below the component in contact with it, and another where the other component is placed above or below the component via yet another component.

[0012] Figure 1 is a schematic diagram showing an example of the apparatus of the present disclosure, and Figure 5(a) is a schematic perspective view showing another example of the apparatus of the present disclosure. As shown in Figures 1 and 5(a), the apparatus 10 of the present disclosure comprises an apparatus body 1, a movable part 2 positioned on the apparatus body 1 that acts on a workpiece W, and a jig 3 for positioning the workpiece W in a position where the movable part 2 can act. A first push button B1 is positioned on the apparatus body 1, and a second push button B2 is positioned on the jig 3. The movable part 2 can move while both the first push button B1 and the second push button B2 are pressed.

[0013] The device disclosed herein has a first push button on the device body and a second push button on the jig, and the movable part can move while both the first and second push buttons are pressed. Therefore, while the movable part is moving, the operator is pressing the first push button with one hand and the second push button with the other hand, thus preventing the operator's hands or fingers from getting caught between the movable part and the workpiece. Furthermore, because the second push button is located on the jig, it is possible to perform work using the jig while the second push button is being pressed. Therefore, even while pressing both the first and second push buttons with both hands, it is possible to perform conventional work using the jig in parallel while sending a signal to the device to activate the movable part (hereinafter sometimes referred to as a movable signal). On the other hand, when the operator releases their hand from at least one of the first and second push buttons, the device operates in a safe direction. In particular, since jigs with a second push button are used around movable parts, if danger is imminent to the worker while working with the jig, the worker can make a quick decision to stop the transmission of the movable part's movement signal to the device.

[0014] Traditionally, it has been recommended that workers use jigs when working around the moving parts of equipment. However, it is conceivable that workers may stop using jigs due to a lack of awareness. This disclosure makes it possible to systematize the use of jigs in conjunction with work, regardless of the worker's awareness.

[0015] Thus, according to this invention, it is possible to provide a device that can improve safety while suppressing a decrease in work efficiency.

[0016] The configuration of the main body and movable parts of the apparatus in this disclosure varies depending on the type of apparatus and is not particularly limited. Furthermore, the jig is not particularly limited as long as it is shaped so that hands and fingers do not come into contact with the movable parts and it is possible to work while pressing the second push button.

[0017] The apparatus described herein includes the following first and second embodiments. Each embodiment will be described in detail below.

[0018] A. First Embodiment In a cutting machine used in a printing factory or the like, an operator moves the stacked paper placed on the mounting table of the cutting machine to the cutting position on the mounting table, operates the clamping mechanism to clamp it, and then operates the cutting mechanism to perform cutting.

[0019] Although conventional cutting machines have safety measures regarding the operation of the cutting blade of the cutting mechanism, there may be cases where no safety measures regarding the operation of the clamping mechanism are provided, and there may be cases where hands or fingers are clamped during clamping.

[0020] FIG. 1 is a schematic diagram showing an example of the apparatus of this embodiment. As shown in FIG. 1, the apparatus 10 in this embodiment is a cutting machine 10A. The cutting machine 10A includes an apparatus main body 11, a clamping mechanism disposed on the apparatus main body 11 and having a pressing portion 12 for clamping a cutting object W1 at a cutting position, a cutting mechanism for cutting the cutting object W1 clamped by the clamping mechanism, and an aligning jig 13 for disposing the cutting object W1 at a position where the pressing portion 12 can act. The pressing portion 12 is a member that descends to press and fix (clamp) the cutting object W1 from above. In FIG. 1, the pressing portion 12 shows the state after descending. <unk>

[0021] In the apparatus 10 of this embodiment, a first push button B1 is disposed on the apparatus main body 11. In FIG. 1, two first push buttons are disposed on the apparatus main body 11, a first push button B1R is disposed on the right front side of the mounting table 15, and a first push button B1L is disposed on the left front side of the mounting table 15. A second push button B2 is disposed on the aligning jig 13. The pressing portion 12 can descend while both any one of the first push buttons B1L and B1R and the second push button B2 are pressed.

[0022] In this embodiment, the left-right direction is defined as the direction when the device is viewed from the operator's side during operation. The front-back direction is defined as the direction towards the operator (towards the user) when the device is viewed from the operator's side.

[0023] In this embodiment, the presser foot 12 is the movable part 2, the alignment jig 13 is the jig 3, and the object to be cut W1 corresponds to the workpiece W. The cutting machine 10A further includes a foot pedal 14 for lowering the presser foot 12. The foot pedal 14 is installed at the bottom of the device body 11 so that it can be pressed down by the operator's foot. The device body 11 has a mounting table 15 on which the object to be cut W1 is placed, and a back gauge section that determines the position of the rear end of the object to be cut W1.

[0024] Conventional cutting machines lowered the clamping mechanism 12 simply by operating a foot pedal, which sometimes resulted in workplace accidents where hands or fingers were caught while temporarily holding the workpiece W1 in place. To ensure safety, it is also conceivable to place two-handed push buttons on the main body of the device to lower the clamping mechanism, but this would require the operator to press both push buttons with both hands after aligning the workpiece. Furthermore, when using an alignment jig, the operator would need to release their hands from the alignment jig after aligning the workpiece and then press both push buttons to lower the clamping mechanism. This could reduce work efficiency.

[0025] In this embodiment of the cutting machine, the second push button B2 located on the alignment jig 13 and one of the two first push buttons B1L and B1R located on the main body of the device constitute a two-handed push button. The pressing mechanism becomes able to descend while the operator is simultaneously pressing these two-handed push buttons with both hands. The pressing mechanism begins to descend when the foot pedal is pressed with the two-handed push buttons pressed, pressing down on the object to be cut W1 from above. In other words, if only the first push button B1 or only the second push button B2 is pressed, the pressing mechanism 12 will not descend even if the foot pedal 14 is pressed.

[0026] According to this embodiment, safety can be ensured by preventing accidents in which hands or fingers are caught in the clamping mechanism of the cutting machine (clamp finger pinching accidents). Furthermore, since the first push button is located on the main body of the device and the second push button is located on the alignment jig, an operator standing within reach of the first push button on the main body of the device can freely perform work using the alignment jig within reach of the other hand. Therefore, it is possible to perform both the work of aligning the edges of the object to be cut and the two-handed pushing operation to lower the clamping mechanism. As a result, work efficiency is not compromised.

[0027] The various components of the apparatus in this embodiment will be described in detail below.

[0028] 1. Alignment jig Figures 2(a) to 2(c) are perspective views showing an example of the alignment jig 13 in this embodiment. As shown in Figures 2(a) to 2(c), the alignment jig 13 is equipped with a second push button B2 and has a shape that allows the edges of the material to be cut to be aligned by pressing the second button without the hands and fingers touching the pressing part. Therefore, even while operating with both hands, conventional work can be performed in parallel while transmitting the movement signal of the movable part. The alignment jig 13 is used by being placed on a mounting table 15.

[0029] As shown in Figure 2(a), the alignment jig 13 has, for example, a main body 13A and a button attachment part 13B. The main body 13A has a handle 31 extending horizontally, an insertion part 32 for inserting the button attachment part 13B, and a flat part 33 for aligning the ends of the object to be cut W1.

[0030] The handle 31 extends horizontally and can be any shape that allows a worker to grip it with their hand; a columnar shape is preferred.

[0031] Preferably, the main body 13A has two insertion parts 32 on both sides in the extending direction of the handle 31. By using a aligning jig with such a structure, the second push button B2 can be easily repositioned to the left or right according to the operator's dominant hand. For example, if the operator is right-handed, as shown in Figure 2(b), the button mounting part 13B is inserted into the insertion part 32 on the left side of the handle 31. This allows the operator to grip the handle 31 with their right hand and press the second push button B2 with their right thumb. If the operator is left-handed, as shown in Figure 2(c), the button mounting part 13B is inserted into the insertion part 32 on the right side of the handle 31. This allows the operator to grip the handle 31 with their left hand and press the second push button B2 with their left thumb.

[0032] The button mounting portion 13B has a second push button B2 attached to it, and is shaped to be insertable into the insertion portion 32 of the main body portion 13A. It is preferable that the second push button B2 is positioned to face forward (towards the operator) when the button mounting portion 13B is inserted into the main body portion 13A.

[0033] The second push button B2 is preferably a wireless button that wirelessly transmits a signal to a control unit that controls the movement of the pressing part. Because it can transmit signals related to button operation wirelessly, there are no restrictions on the installation location compared to wired buttons. Furthermore, unlike wired buttons, wireless buttons do not have tangled wires. If wires become tangled during work, it may be difficult for the worker to use the jig safely. Also, it may require extra effort to untangle the wires, which may reduce work efficiency.

[0034] If the second push button is a wireless button, it is preferable that the second push button is equipped with a generator. By using a push button equipped with a generator, a battery is not required and charging operations are not necessary. As an example of a push button equipped with a generator, the "Wireless Push Button XB5R / XB4R type (manufactured by Fuji Electric Equipment Control Co., Ltd.)" can be used.

[0035] 2. Clamping mechanism The clamping mechanism is located above the mounting base 15 and includes a pressing portion 12 and a lifting mechanism (not shown) for raising and lowering the pressing member 12. The lifting mechanism of the clamping mechanism is controlled by a control unit to allow it to move up and down.

[0036] The pressing mechanism descends and uses its weight to press down on and secure the object to be cut. The pressing mechanism is, for example, located close to the rear of the cutting blade of the cutting mechanism.

[0037] 3. Cutting mechanism The cutting mechanism is located above the mounting table 15 and includes a cutting blade for cutting the object to be cut and a drive mechanism for driving the cutting blade. The drive mechanism of the cutting mechanism is controlled to be drivable by the control unit.

[0038] The cutting mechanism activation button, which operates the cutting mechanism, is fixedly positioned on the main body of the device, for example. Preferably, two cutting mechanism activation buttons are provided, one on each side of the front end face of the mounting table 15 of the main body of the device 11, and the cutting mechanism is activated by pressing them simultaneously with both hands. In this case, it is preferable that the cutting mechanism activation buttons are positioned next to the first push buttons B1L and B1R described above.

[0039] The drive mechanism of the cutting mechanism and the lifting mechanism of the clamping mechanism are controlled independently by the control unit to allow them to move up and down.

[0040] 4. Main unit of the device As shown in Figure 1, the main body of the device 11 has a cutting object insertion opening 16 formed at a predetermined height position, which penetrates in the front-to-back direction, and a mounting table 15 for placing the cutting object, which extends from the front to the front of the cutting object insertion opening 16.

[0041] The device body has a first push button. There may be one or two first push buttons. As shown in Figure 1, it is preferable that the first push button B1 is located on both the right and left sides of the front end face of the mounting base 15. This is so that the operator can choose which first push button to use depending on their dominant hand. For example, if the operator is right-handed, they can hold the alignment jig 13 with their right hand and press the first push button B1L located on the left side with their left hand. If the operator is left-handed, they can hold the alignment jig 13 with their left hand and press the first push button B1R located on the right side with their right hand.

[0042] 5. Control Unit The cutting machine in this embodiment has a control unit. The control unit independently controls the drive mechanism of the cutting mechanism and the lifting mechanism of the clamping mechanism.

[0043] The control unit is connected to the lifting mechanism of the clamp mechanism, as well as to the first push button, the second push button, and the foot pedal. The control unit receives signals from the first and second push buttons and lowers the clamping part while the foot pedal is pressed down.

[0044] Furthermore, the control unit is connected to the drive mechanism of the cutting mechanism, as well as a button to activate the cutting mechanism. When the control unit receives a signal from the cutting mechanism activation button, it activates the cutting mechanism.

[0045] 6. Items to be cut Examples of materials to be cut include laminates of sheet-like or plate-like articles. The articles mentioned above are not particularly limited, but examples include paper, woven fabric, nonwoven fabric, resin sheet, rubber sheet, particleboard, pressboard, metal vapor-deposited sheet, decorative sheet, gasket sheet, packing sheet, etc.

[0046] 7. Example of operation Figure 3 is a flowchart showing the work procedure using the cutting machine in this embodiment. First, the operator places the object to be cut on the cutting machine's mounting table, inserts a predetermined amount through the insertion opening, and aligns the object to be cut using the alignment jig (S1). At this time, the operator grasps the handle of the alignment jig and aligns the object to be cut by bringing the alignment jig into contact with the end face of the object on the mounting table.

[0047] Next, the worker grasps the alignment jig 13 and simultaneously presses the second push button B2 located on the alignment jig 13 and the first push button B1 located on the device body 11 with both hands (S2). In this case, if the worker is grasping the handle 31 of the alignment jig 13 with their right hand, they may press the second push button B2 with their right thumb while holding the handle 31 of the alignment jig 13, and press the left first push button B1L located on the device body 11 with their left hand. Alternatively, if the worker is grasping the handle 31 of the alignment jig 13 with their left hand, they may press the second push button B2 with their left thumb while holding the handle 31 of the alignment jig 13, and press the right first push button B1R located on the device body 11 with their right hand.

[0048] Next, the worker presses the first push button B1 and the second push button B2 with both hands while stepping on the foot pedal 14 (S3). Figure 4(a) shows the worker pressing the left first push button B1L with their left hand and the second push button B2 with their right hand while stepping on the foot pedal 14. Figure 4(b) shows the worker pressing the right first push button B1R with their right hand and the second push button B2 with their left hand while stepping on the foot pedal 14.

[0049] As a result, the retaining part 12 begins to descend (S4). If you release your hand from at least one of the first and second push buttons, the retaining part 12 will rise. When you fully depress the foot pedal 14 (S5), the limit switch turns ON and the retaining part completes its descent. After the limit switch turns ON, an electrical counter starts counting and, after it has completed counting a predetermined set time (for example, after counting 1 second of the set time) (S6), the retaining part 12 remains in the lowered position even if you release your hands from both push buttons.

[0050] Next, release your hands from the first push button B1 and the second push button B2 (S7). By pressing the cutting mechanism activation button (S8), the object to be cut W1 is cut. Next, release your foot from the foot pedal (S9). This turns off the limit switch.

[0051] B. Second Embodiment In printing systems, a winding machine is sometimes used to wind printed material onto a core. Such a winding machine has, for example, a movable chucking part that can move back and forth and fits into the open end of the object to be attached, such as a core.

[0052] Traditionally, when attaching a winding core to such a movable chucking mechanism, the worker would support the core with one hand while pressing the movable button on the chucking mechanism with the other hand to engage the mechanism with the end of the core. Therefore, depending on how the core was supported, there was a risk of workplace accidents such as pinching hands or fingers. Furthermore, if the button to activate the movable chucking mechanism were a two-hand push button to ensure safety, the worker would be unable to support the core.

[0053] Figure 5(a) is a schematic diagram showing an example of the apparatus of this embodiment. In this embodiment, apparatus 10 is a winding machine 10B. The winding machine 10B includes an apparatus body 21 and a chucking mechanism C arranged on the apparatus body 21 that rotatably and detachably supports the object to be attached W2. The chucking mechanism C includes a movable chucking part 22 that can move forward and backward toward the end of the object to be attached W2. Furthermore, the winding machine 10B includes a receiving jig 23 that supports the object to be attached W2 in order to position the object to be attached W2 in a position where the movable chucking part 22 can operate. Figure 5(b) is a schematic diagram of a winding core, which is an example of the object to be attached W2.

[0054] In this embodiment, the winding machine 10B has a first push button B1 on the device body 21 and a second push button B2 on the receiving jig 23. The movable chucking part 22 can move while both the first and second push buttons are pressed.

[0055] In this embodiment, the movable chucking part 22 corresponds to the movable part 2, the receiving jig 23 corresponds to the jig 3, and the object to be attached W2 corresponds to the object to be worked on W.

[0056] According to this embodiment, the movable chucking part moves toward the end of the object to be attached while the first push button fixed to the device body and the second push button located on the receiving jig are pressed simultaneously with both hands. In other words, the movable chucking part will not operate unless both the first push button B1 fixed to the device body and the second push button B2 located on the receiving jig 23 are pressed. Therefore, when chucking the winding core into the movable chucking part, accidents in which hands or fingers are caught between the movable chucking part and the winding core can be prevented, thus ensuring safety.

[0057] Furthermore, since the first push button is located on the device body and the second push button is located on the receiving jig, an operator standing within reach of the first push button on the device body can freely perform operations using the receiving jig within reach of the other hand. Therefore, it is possible to simultaneously perform tasks such as supporting the object to be attached and two-handed pressing operations to move the movable chucking part. As a result, work efficiency is not compromised.

[0058] The various components of the apparatus in this embodiment will be described in detail below.

[0059] 1. Receiving jig The support jig in this embodiment is used to support an object to be mounted so that the movable chucking part can be fitted into the open end of the object to be mounted. Figure 6(a) is a perspective view showing an example of the support jig 23 in this embodiment. Figure 6(b) is a view of the support jig 23 shown in Figure 6(a) from below. As shown in Figure 6, the support jig 23 has a second push button B2 attached to it and has a shape that allows the user to support the object to be mounted while pressing the second button without the hand and fingers touching the movable chucking part. Therefore, it is possible to perform both the work of supporting the object to be mounted and the two-handed pushing operation to move the movable chucking part.

[0060] As shown in Figures 6(a) and 6(b), the receiving jig 23 has, for example, a top surface 41 that supports the object to be mounted, and three side surfaces 42, and is provided with an insertion opening 43 at the front into which a worker can insert their hand. Preferably, the top surface 41 has V-grooves extending in the left-right direction to prevent the object to be mounted from rolling. Preferably, a sheet is attached to the surface of the top surface from the viewpoint of preventing the object to be mounted from slipping, preventing damage, or both. The sheet is not particularly limited as long as it has the characteristics of at least one of a non-slip material and a soft material.

[0061] The left-right direction of the support jig is defined as the direction the support jig is viewed from the worker's perspective while the worker is using the support jig. The front-back direction is defined as the direction towards the worker (towards the worker) when the support jig is viewed from the worker's perspective while the worker is using the support jig.

[0062] As shown in Figures 6(a) and 6(b), the receiving jig 23 preferably has a handle 44 fixed to the back side of the upper surface 41. With such a structure, the worker will hold the receiving jig 23 by grasping the handle 44, so if the hand or fingers are surrounded and pinched by the receiving jig 23, the jig portion will be pinched before the hand or fingers. The handle 44 is preferably fixed to the center of the back side of the upper surface 41.

[0063] As shown in Figures 6(a) and 6(b), the second push button B2 is preferably located on the handle 44. In particular, the second push button B2 is preferably located on the side of the handle opposite to the insertion opening 43 (the rear side). Furthermore, the mounting location of the second push button is preferably near the center in the left-right direction on the side of the handle opposite to the insertion opening. With this arrangement, the second push button can be pressed with the middle finger, making it usable regardless of whether the operator is left- or right-handed.

[0064] It is preferable that the receiving jig does not have a lower surface that is opposite to the upper surface. If the lower surface of the receiving jig is covered, if the operator's hands are large, their hands may not be able to fit into the receiving jig, and the possibility of the lower surface being caught in the movable chucking part is low.

[0065] The second push button B2 is preferably a wireless button that wirelessly transmits a signal to a control unit that controls the movement of the pressing part. Because the signal related to the operation of the button can be transmitted wirelessly, there are no restrictions on the installation location compared to wired buttons. Furthermore, unlike wired buttons, wireless buttons do not get tangled. If the wires get tangled during work, it may be difficult for the worker to use the jig safely. Also, it may require time to untangle the wires, which may reduce work efficiency. As for the wireless button, the same type as the wireless button in the first embodiment can be used.

[0066] 2. Chucking mechanism The winding machine in this embodiment has a chucking mechanism C arranged on the device body 21 that rotatably and detachably supports the object to be attached W2. The chucking mechanism has a movable chucking part 22 that can move back and forth and fits into one open end of the object to be attached W2, and a non-movable non-movable chucking part 29 that fits into the other open end of the object to be attached W2. The movable chucking part 22 and the non-movable chucking part 29 rotatably and detachably support the object to be attached W2. The chucking mechanism has a movable chucking part 22 and a non-movable chucking part 29, and a drive mechanism (not shown) for moving the movable chucking part 22. The drive mechanism is controlled by a control unit.

[0067] The winding machine 10B in this embodiment may have multiple chucking mechanisms. For example, as shown in Figure 5, the winding machine 10B has a first chucking mechanism C1 and a second chucking mechanism C2 that rotatably and detachably support an object to be attached between the ends of a pair of arm portions 25, which will be described later.

[0068] 3. Main unit of the device As shown in Figure 5, the main body of the device 21 preferably includes, for example, a rotating body 24 and a support base 28. The rotating body 24 includes, for example, a support column 26 extending in the left-right direction, a pair of arm portions 25 connected to the support column in a left-right opposing position, and a shaft 27.

[0069] Each arm section 25 is made of a strip-shaped member and is positioned opposite to the left and right at a predetermined distance apart, with the longitudinal center of the opposing surfaces connected by a support column 26. The shaft 27 extends in the left-right direction through the inside of the support column 26, and both ends of the shaft protrude through the arm section 25. The ends of the shaft 27 protruding from each arm section 25 are pivotally supported on a support base 28. Inside the support base 28, for example, a control device and a drive mechanism for rotating the shaft 27 are provided. As a result, the pair of arm sections 25 can rotate around a rotation axis that extends in the left-right direction.

[0070] The first push button can be located on the main body of the device. In particular, it is preferable to have it located on the arm portion 25, as shown in Figure 5. Furthermore, it is preferable to have it located around the longitudinal end of the arm portion 25. This is because it makes it easier for the operator to press both the first and second push buttons with both hands.

[0071] 4. Control Unit The control unit is connected to the drive mechanism of the movable chucking unit, as well as to the first and second push buttons. The control unit activates the drive mechanism of the movable chucking unit while receiving signals from the first and second push buttons.

[0072] 5. Object to be attached Examples of objects to which it can be attached include a coil core that does not have any long material wound on it.

[0073] 6.Applications The winding machine in this disclosure is typically used in conjunction with a predetermined system that continuously performs processes such as printing and coating on a web being transported.

[0074] In this embodiment, if the winding machine has the rotating body described above, it may be configured to continuously wind the long object by switching the roll, which is supported by one chucking mechanism and has the long object wound (finished winding), to a winding core supported by the other chucking mechanism. Figure 5 shows the state in which the roll being wound is supported by one chucking mechanism C2, and before the winding core is attached to the other chucking mechanism.

[0075] 7. Work Procedure The work procedure using the winding machine in this embodiment will now be described. First, the worker attaches the end of the object to be attached W2 to the non-movable chucking part 29 of the chucking mechanism. Next, as shown in Figure 7, the worker grasps the handle of the receiving jig 23 and supports the object to be attached W2 from below with the receiving jig 23.

[0076] Next, the worker grasps the handle of the receiving jig 23 and simultaneously presses the second push button B2 located on the receiving jig 23 and the first push button B1 located on the device body 11 with both hands. This causes the movable chucking part 22 to move toward the end of the object to be attached W2.

[0077] After the movable chucking section 22 chucks the object W2 to be attached, release your hands from the first push button B1 and the second push button B2. As a result, both ends of the object W2 to be attached are chucked by the chucking mechanism.
