Description

[Detailed explanation of the idea] [Fields of industrial use] TECHNICAL FIELD The present invention relates to a peripheral delimiting device for elongated objects.

[Prior Art] The elongated object is, for example, a tube-shaped material having a certain length, or alternatively, it may be a solid body. moreover,
The elongate object may be a flexible or rigid object of cylindrical cross-section or any other shape. Examples of materials for this object include plastic, rubber, metal,
Any material such as cardboard can be used.

The term "peripheral delimitation" as used herein includes a relative rotational movement between a working element of a device and an elongated object about the central axis of this object, whereby said working element gradually moves around the periphery of the elongated object. shall mean applying motion to an elongated object.
Thus, for example, if the elongate object is a cylindrical tube of a certain length and the operation being performed is a cutting operation, then the cutting tool element of the device can A tube of a predetermined length is then cut from the remainder of the tube body. However, this operation is not necessarily limited to cutting, but can also be used, for example, to form grooves around elongated objects or to mark their surfaces.

An object of the present invention is to provide a device for performing circumferential division work on a long and slender object, such as cutting into a tube body of a certain length. It is something that will be done.

Another object of the invention is to perform such operations in rapid succession at a plurality of equally spaced cross-sections along the length of an elongate object.

Another object of the present invention is to provide an apparatus that automatically performs such operations in response to peripheral demarcation operations of elongated objects in each operation ready state.

A further object of the present invention is to provide a device in which such operations can be performed repeatedly with relatively simple equipment, but automatically and in response only to the continuous movement of applied forces, i.e. or other operating elements, and a device for continuously applying a longitudinal force to advance an elongated object through the device of the present invention.

The invention is particularly suitable for use, but not exclusively, in cutting lengths of thin-walled plastic or metal tubes, such as flexible draw tubes for toothpaste or cosmetic filling purposes. suitable.

[Means for Solving the Problem] The above objects provide a hollow holding device for holding an elongated object along a central axis against its movement, and a tool head rotatable about the central axis relative to the holding device. a body member; and a tool member pivotally supported on the tool head body member eccentrically with respect to the central axis and parallel to the pivot axis, the tool member pivoting in the direction of the central axis in direct response to deceleration of the tool head. a tool head for pivoting, a drive for rotating the tool head, a brake for decelerating the tool head, and an elongate member located at a predetermined axial distance from the tool member and held by a holding device. and a control element arranged to actuate a brake in response to the presence of an approaching free end of the object, thereby pivoting the tool member radially toward the elongated object. This is achieved by a peripheral delimiting device for an elongated object, characterized in that it performs a peripheral delimiting operation and is further arranged to release the brake when said free end of the elongated object leaves the control element.

A feature of the invention is that the device according to the invention holds an elongate object, for example a tube of a certain length, and performs, e.g. It is configured to perform peripheral separation operations such as. The tool member is eccentrically pivoted to a tool head body member which rotates about a central axis along which the elongated object lies. The tool member thus moves according to a trajectory around the elongated object.

The device includes a brake for decelerating the rotating tool head, wherein when the tool head is decelerated by the action of the brake, the tool member directly responds to this deceleration in the direction towards the central axis. and swivels about its pivot, thereby bringing it into a working position on an elongated object to carry out circumferential demarcation operations.

The cutting or other circumferential delimitation operation is carried out at a predetermined axial distance from the free end of the tube or other elongated object;
The apparatus includes a control element (eg, an electrical limit switch) spaced along a predetermined distance from the tool member. The control element is operated in response to engagement of the control element with the free end of the elongate object to apply the brake. The separating operation can thus be carried out when the elongate object is ready for such operation, and therefore in this state.

Furthermore, the control element is arranged such that the brake is released when the free end of the elongate object is no longer in close proximity to the control element. Thus, for example, if the separating operation is a cutting operation, the brake is released when the cutting operation cuts an elongated object of a predetermined length and falls from the vicinity of the control element at the end of the cutting operation.

Preferably, the tool member is pivoted towards the central axis so as to effect its separation into elongated objects by applying a positive force to the tool member. Preferably, this positive force is generated by relative rotational movement between the tool head (including the tool member itself) and other members. Most conveniently, said other member comprises a brake drum, which is part of the brake which rotates freely with the tool head, and which rotates at the same rotational speed as the tool head when the brake is not activated.

The brake includes a device that decelerates the brake drum when the brake is applied, the brake drum being configured to rotate coaxially with the tool head while allowing limited relative rotation between the brake drum and the tool head. There is. The brake drum and tool member are coupled such that when the brake is applied, this limited relative rotation causes the brake drum to pivot the tool member axially and force it forward.

Returning to the control element mentioned above, this element is preferably coupled to the drive of the device effecting the rotation of the tool head in such a way that the drive does not operate in the absence of any or partial brake application.
Therefore, when a retarding force is applied to the tool head by the brake, the tool head continues to rotate under its own momentum and the momentum of any other parts rotating with it, until the brake is released. It is not subject to any external influences (other than those exerted by the brakes) until When the brake is released, for example by actuation of the control element, the drive is reactivated to drive the tool head, and the control element preferably causes the drive and the brake to reactivate the tool head and drive at about the same time as the brake is released. Join.

The holding device includes a releasable clamp for holding the elongated object against axial movement during a circumferential sectioning operation, and the clamp is configured such that the clamp engages the elongated object at the same time as the brake is applied. It is desirable to have a structured control element. Similarly, the clamp and brake are released simultaneously.

The device according to the present invention can be used to cut an extremely long tube into tubes of the same size one after another, or a series of tubes each having a predetermined length, or a series of tubes each having a predetermined length. It is particularly suitable for automatically carrying out repetitive peripheral delimitation operations on elongated objects or series of elongated objects, such as cutting into several tubes that are a continuation of tubes. This automatic operation for such purposes is accomplished by applying and releasing the brake (and preferably disengaging and recoupling the drive and tool head, and engaging and disengaging the clamp as described above). , a device as described above having a control element such as a control switch arranged to keep the drive device in continuous rotation and to maintain a continuous force pushing a length of tube forward through a retaining device of the device. It is enough just to provide it. A tube body of a predetermined length is captured each time its front end reaches the control element in which the cutting or detachment operation is carried out automatically. Once the severed tube body is dropped, the tube material advances to cut a new length of tube.

[Example] Next, the present invention will be described with reference to the drawings.

In FIG. 1, the device shown has a fixed main frame 10 (only the upper part of which is shown).
The main frame 10 includes a main drive in the form of an electric motor 11, a tube cutting unit generally indicated at 12;
Tube material guide 13, electric control box 14, hydraulic controller 15, electric/hydraulic valve 16, and discharge slope 1
It carries 7.

The tube cutting unit 12 is connected to the main frame 10.
2 and 3, and will be described in detail below with respect to FIGS. 2 and 3. A protective shroud 19 extends over the tube cutting unit 12 and carries a horizontal bar 20 secured to the main mounting plate 18 and extending beyond the unit 12. Rod 20 carries an end stop 21 that includes a block 22 that is attached to the rod at any desired location along the rod and is adjustably coupled to a switch mounting block 24 using a screw 23. is fitted with a control element in the form of an electrical limit switch 25, the purpose of which will become clear from the description below.

The discharge ramp 17 is fixed to the frame 10 below the limit switch 25 and extends downwardly away from the left or outlet end of the tube cutting unit 12. The tube material guide 13 comprises a guide ring 26 carried by a horizontal bar 27 which is slidable in a block 28 fixed to the main frame 10.
including. Rod 27 is adjustably fastened to block 28 to define the desired distance between guide ring 26 and the right or inlet end of tube cutting unit 12. The limit switch 25 is electrically connected (as shown by the dashed line) to the electro-hydraulic valve 16 and the motor 11 for a purpose to be described later. Power for the motor 11 and valve 16 is provided by the control box 1.
4.

The electro-hydraulic valve 16 is supplied with pressurized hydraulic fluid (from a source not shown) via a regulator 15 and has two hydraulic valves connected to a hydraulic brake actuator 31 and a hydraulic engagement actuator 32, respectively. It has outflow lines 29 and 30. Actuators 31 and 3
2 are attached to the main frame 10 below each of the outlet and inlet ends of the tube cutting unit 12.

2 and 3, the tube cutting unit 12 continuously cuts a length of tube from a continuous tube blank 33, which is shown in solid lines in FIG. 1 and in dashed lines in FIGS. 2 and 3. 35
(Fig. 1). In this embodiment, the tube material consists of a thin walled flexible plastic continuous tube. Cutting of the tube stock is carried out at the cross section of the tube indicated at 34 in FIGS. 1 and 2 near the outlet end of the tube cutting unit.

The tube cutting unit includes a fixed cylindrical guide sleeve 36 having a length significantly greater than its inner diameter and cantilevered from the mounting plate 18, a clamping device generally indicated at 37, a tool head indicated at 38, and a belt. It consists of an outer sleeve 39 to which a pulley 40 is attached and a brake drum 41. The fixed guide sleeves 36 each have an end portion with an inner diameter 42 within which the tube blank 33 can easily slide, but with little radial play, so that the inner diameter 42 is aligned with the axis of the tube 33. The horizontal central axis 43 of the tube cutting unit is precisely matched. Clamping device 37 includes a clamping plate 44 having an inner diameter that is the same as inner diameter 42, as shown in FIG. The clamping plate 44 is movable vertically in a fixed guide 45 by means of the clamp actuator 32 (FIG. 1) to which it is mounted. The clamping device 37 and the fixed guide sleeve 36 together constitute a hollow holding device for holding the tube blank (or other elongated object having the same diameter) therein along the central axis 43. . Fixed guide sleeve 36 is attached to mounting plate 18 by a flanged mounting sleeve 46 fixed coaxially around the guide sleeve.

The tool head 38 includes a tool head body member in the form of a face plate 47 having a central bore through which the free end of the fixed guide sleeve 36 passes coaxially with the face plate, and the tool head 38 further includes a cutting tool element 49.
It includes a tool member in the form of a cutter arm 48 to which a cutter arm 48 is attached. The cutter arm 48 has a central axis 4
It is pivoted to the face plate 47 by a pivot pin 50 that is parallel to but eccentric to the cutter 3 and forms a cutter pivot. The face plate 47 is coaxially fixed to the outer sleeve 39 with its end abutting, and the face plate 47 is mounted by means of bearings 51 with the mounting sleeve 46 inserted therein, so that the tool head 38 can be moved around the fixed guide sleeve 36. can be rotated freely.
This rotation is caused by a motor 11 (FIG. 1) having a shaft on which a belt pulley 52 (FIG. 1) is mounted, and a belt pulley 40 fixed to the outer sleeve 39.
This is implemented by a drive device including a drive belt 53 connecting a pulley 52 and a drive belt 53 . This direction of rotation is the first
It is as indicated by the arrow in the figure and FIG.

The cutter arm 48 is arcuate and extends from the pivot pin 50 in a rotationally aft direction (relative to the direction of rotation of the tool head 38). A cutting tool element 49 is mounted near the free end of the cutter arm 48 and is configured to make a radial cut through the wall of the chop 33, as will be briefly described below. The cutter arm also includes a short lever element 54 projecting radially outwardly from the pivot for engaging an actuating element in the form of a detent 55 shown in FIG. 3 formed on the inner peripheral surface of the brake drum 41.

The cutter arm 48 and the cutting tool element 49 are part of the tool head 38, but can take any form that satisfies the requirements of the claims.

The device is equipped with a brake to slow down the rotation of the tool head 38. This brake consists of a brake drum 41 and a brake shoe 56,
Brake shoe 56 is movable into engagement with and away from brake drum 41 by brake actuator 31 shown in FIG. 1 to apply and release the brake. The brake drum 41 has a ring shape that is rotatable by a bearing provided on a trunnion portion of a face plate 47 coaxial therewith. A suitably high-friction material liner ring 57 is carried by the brake shoe at its interface with the faceplate 47, thereby entraining the brake drum as the faceplate rotates until a positive deceleration force is applied to the brake drum. This causes the liner ring 57 to slide on the faceplate 47, allowing relative rotation to occur between the faceplate 47 and the brake drum.

Although the face plate 47, brake drum 41, brake shoe 56, and liner ring 57 are embodiments of a tool head body member and a brake, respectively, they can take any form as long as they satisfy the conditions set forth in the claims.

In operation, the motor 11 is maintained in continuous operation and a constant supply of pressurized hydraulic fluid is sent to the electro-hydraulic valve 16 via the hydraulic control unit 15. With the tightening block 22 in front, the limit switch 25 is removed from the tube blank 33 by the cutting tool element 49 a distance approximately equal to the required length L of each tube 35 shown in FIG. 1 to be cut by the device. Once the limit switch 25 is set at a position on the rod 20 away from the defined vertical cutting plane 34, the limit switch 25 is adjusted to maintain exactly this distance from the plane 34 using the precision adjustment screw 23. Set. A constant axial force F is applied to the tube blank to continuously push the tube blank towards the limit switch 25, i.e. in the direction indicated by arrow A in FIG. The device for applying this force is not shown in the figures; it can also be accomplished, for example, simply by the operator holding the tube blank and pushing it forward with a constant force. Alternatively, it is also possible to use any suitable mechanical device, such as a fluid pressure actuated ram or a spring-loaded drum around which the tube stock is wrapped and from which it is forced out towards the tube stock guide 13. . The front end of the tube blank is guided through the guide ring 26 of the guide 13 and then through the clamping device 37 and the guide sleeve 36.

The front end of the tube material 33 is the limit switch 25
When engaged, the limit switch 25 closes. This has a double effect: the motor 11 is deenergized and the electro-hydraulic valve 16 is opened. Motor 1
The face plate 47, which has been continuously rotating due to the rotation speed 1, continues to freely rotate as a flywheel. Similarly, the brake drum 41 is rotating together with the face plate 47,
In the relative rotational position shown in solid lines in FIG. It is arranged with respect to the pivot pin 50 so that it can be rotated.

However, when valve 16 opens, brake actuator 31 and clamp actuator 32 operate simultaneously. The clamp actuator moves the clamping plate 44 upwardly, thereby firmly restraining longitudinal movement of the tube stock in either direction. The brake actuator engages the brake shoe 56 with the brake drum 41, and the brake drum 41 is decelerated. This deceleration effect is transmitted to the face plate 47 via the liner ring 57, but due to the flyhole effect of the face plate 47, this face plate 47 is not decelerated at the same rate as the brake drum, so that the brake drum is is rotated to a new rotational position relative to the face plate 47 as shown by the dashed line at , thereby exerting a rearward tangential force K on the lever 54 . In this way, the cutter arm 48 is positively pushed to pivot radially inwardly toward the central axis 43 so that the cutting tool element 49 engages the tube blank 33 in the cutting plane 34 . During the next rotation of the tool head body, this tangential force K (FIG. 3) is maintained so that the cutting tool element 49 circumscribes the tube blank 33 and cuts into the tube to cut the tube body 35 of a predetermined length L. cut.

This cut tube body 35 is connected to the discharge ramp 17.
It falls through its own weight. In this state, the limit switch 25 is released and the brake actuator 31
and the clamp actuator 32 is therefore deenergized by the electro-hydraulic valve 16. At the same time, the motor 11 is energized again. Since the brake is released when the brake actuator is deenergized, the brake drum 41 is no longer restrained and rotates freely with the face plate 47. The motor again drives the face plate 47 and the face plate 47 is accelerated to its normal speed, which is caused by the removal of the backward tangential force K acting on the lever element 54 by the detent 55 of the brake drum 41 and the cutter arm 48 is returned to its normal position as shown by the solid line in FIG. 3 by centrifugal force. When the cutter arm pivots rearward in this way, the lever element 5
4 causes the brake drum to rotate slightly forward relative to the face plate 47, thereby restoring the brake drum to its normal position against further rotation with the face plate 47.

At the same time, deenergizing the clamp actuator 32 releases the clamp 37 so that the constant axial force F causes the tube blank 33 to advance again until the limit switch 25 and its forward end are reengaged. This initiates the next cycle of operation and cuts another tube 35 of length L. These operating cycles are such that all tube materials 33
It is automatically repeated until the cutting is completed.

4 and 5, the embodiments shown in these figures differ from those shown in FIGS. 1 and 2 only in the details of their design, but the principle of operation is the same. For convenience of illustration, FIGS. 4 and 5 are in the opposite direction of rotation of the tool head 38 in FIGS. 1 and 2. In Figures 4 and 5,
Instead of the belt pulley 40 and the outer sleeve 39, an outer sleeve 60 is provided which constitutes an integral belt pulley, and this outer sleeve 60 is connected to the bearing 5.
1 on the fixed mounting sleeve 46 coaxially. The face plate 47 is attached to this outer sleeve 60.
is fixed. The bushing 6 has an annular liner 64 made of a soft material such as nylon or rubber in place of the clamp 37 shown in FIGS. 2 and 3.
3 to reduce the risk of damage to the tube material when the tube material 33 is tightened in place. The inner bore of the liner 64 has a diameter that allows the tubular material 33 to be rigid yet slidable therein. The piston of the clamp actuator 32 is fixed to a sliding block 62 which slides vertically in a guide 45. An adjustable end stop 65 is provided to limit the upward movement of the sliding block 62, thereby determining the tightness of the tightening effect obtained from the clamp 61.

It will be appreciated that many variations on the device described above may be implemented within the scope of the invention. For example, for some applications, the cutter arm 48 will tend to pivot radially inwardly due to the centripetal force when a deceleration force is applied to the face plate 47 by the brake, so that the cutting tool element 49 or other tool elements radially inwardly. Under these circumstances,
The brake drum 41 can be omitted and the brake shoe 56 or other corresponding braking devices can be arranged to act directly on the face plate 47.
The positive tangential force K exerted by the brake drum 41 causes the cutting tool element 49 to
An environment that ensures that sufficient radial force is applied to the tube stock to satisfactorily cut 3, and that does not require force K, is defined as the environment in which the force K is applied by the cutting tool element during peripheral delimitation operations. The environment is such that all the radial forces required to be applied are provided by centripetal forces.

Also, the "control element" (electrical limit switch 25 in the embodiment described above) need not be in direct contact with the tube stock or other elongate object operated by the device. For example, it may include a proximity switch or reed relay, or a device for generating and sensing a beam that is interrupted by an elongated object.

According to the invention, the tool head 38 with the cutting tool element 49 must rotate in order to exert the necessary centripetal and centrifugal forces on the elongated object being worked on to move it into and out of its working position. However, it is not necessary to forcibly restrain the elongate object itself against rotation, although such restraint is desirable when a clamping action against longitudinal movement is required. However, such a tightening action is not required, and for example, the central shaft 43
is not necessarily horizontal, but may be vertical or inclined to the vertical, in which case the axial force F is imparted in whole or in part by the weight of the tube blank 33 or other elongated object. , which is then supported by engagement of its forward end with a limit switch 25 or other suitable end stop device. Under these conditions, the elongated object may be rotated at different speeds, either in the opposite direction to the tool head, or in the same direction. This is achieved by mounting an object holding device such as a guide sleeve 36 for rotation about a central axis 43, which object holding device can be connected to a drive motor via any suitable coupling device for this purpose. 11.

Also, since the relative rotation between the brake drum 41 and the tool head body member (such as the faceplate 47) is limited by the amount that the lever element 54 can move about its pivot pin 50, the brake drum and faceplate The liner ring 57 can be replaced by a spring or series of springs.

In each of the embodiments shown, the drive device includes an element that is slidable when a brake or drive belt 53 is used. This means that when the brake is applied, for example, if the brake drum is decelerated too rapidly due to dust or the like on the brake shoe 56, an excessive force K is applied to the lever element 54, which could damage the lever. This is a desirable safety feature to protect against. However, other suitable elements capable of providing slippage can also be used, for example a type of clutch that is configured to slip when a predetermined torque is applied.

Any convenient number of tools, each disposed on tool head body 47, may be used to operate in the general manner described above. The device can be easily adapted for processing elongated objects of non-circular cross-section by providing a suitable guiding cross-section for the inner sleeve 36 and other parts, if any, through which the elongated object passes. .
