Description

  The present invention relates to a belt tip processing apparatus, and more particularly to a belt tip processing apparatus that can automate the process of processing a belt tip and improve the process efficiency.

  In general, a belt used for casual purposes includes a buckle made of plastic or the like, and a belt body made of webbing, nylon, leather or the like.

  A webbing belt WB will be described as an example of a conventional general belt. As shown in FIG. 11, the webbing belt WB is coupled to a webbing W made of nylon or the like having a predetermined length with a straight end cut and the other end of the webbing W described above. And a buckle B configured to be fixed or removed with W interposed therebetween.

  Here, if the tip of the webbing belt WB is cut in a straight line, it is difficult to insert the webbing belt WB into the buckle B. Therefore, the tip of the webbing belt WB was manually processed with a curve. Inconveniently, not only is the work efficiency low, but also the webbing W may be unwound after machining, and a lot of curve machining is not performed.

  Therefore, an insertion member 60 made of a material such as a separately curved plastic may be used by being coupled to the tip of the webbing belt WB.

However, in order to use the additional insertion member 60 coupled to the tip of the webbing belt WB as described above, a separate process related to the coupling of the insertion member 60 is further required, and the coupling of the insertion member 60 is also necessary. As a result, the thickness of the webbing W is increased, which makes it difficult to insert the webbing W into the buckle B substantially.
Further, even if the belt tip is manually curved, there is a problem that it is difficult to manufacture the belt because the efficiency of the machining operation is too low.

The transfer unit fixes the belt to be processed by the belt tip end processing apparatus of the present invention and performs step transfer to each process stage.
For this purpose, the transfer unit includes a plurality of jigs 1 each fixing the belt and arranged in parallel with each other at a step transfer interval, and a circulation track type conveyor system 8 for step-transferring the jigs 1. .

  Each jig 1 includes a jig main body 16 that holds a belt, and the jig main body 16 has substantially the same length as the length of the belt to be processed.

  Further, as shown in FIGS. 1, 2 and 4, each jig 1 is held with guide structures 17-1 and 17-2 for preventing the held belt WB from being detached from the fixed position. And a holding part 3 for restraining the belt WB. Further, the jig body 16 further includes an auxiliary guide member such as a bolt 30.

  The guide structures 17-1 and 17-2 desirably include a first guide member 17-1 that contacts the tip of the held belt WB and defines a fixing position in the longitudinal direction of the belt, and the held belt WB. And a second guide member 17-2 which is formed to protrude on both sides and prevents the held belt WB from being detached from the fixed position in both directions.

  The first guide member 17-1 determines the fixing position in the longitudinal direction of the belt by contacting and stopping the front end of the belt WB held by the jig main body 16. Accordingly, any member having a protrusion shape can be used, but a general bolt shape is preferable.

  The second guide member 17-2 is formed to protrude from both side portions of the held belt to prevent the belt from being detached from the fixing position in the lateral direction. As shown in FIG. 4, at least 1 pair or more of such 2nd guide members 17-2 are installed.

  As shown in FIG. 4, the holding unit 3 can adopt a structure in which it is fixed using the elasticity of the held belt. For example, the holding unit 3 includes two support bases 18 installed on both sides of the front end of the jig body 16, a guide hole 19 formed in each of the support bases 18 in a vertical direction, and a guide hole 19. A cylindrical member 20 having both ends inserted therein and installed so as to freely move up and down, and a spring 21 installed on the support base 18 so as to downwardly bring the cylindrical member 20 downward with a certain elastic force, An adjustment bolt 22 that supports the upper stage of the spring 21 and is screwed to the support base 18 so as to adjust the elasticity of the spring 21 is included.

  It is preferable to use at least one loop chain 25 used here. When a plurality of loop chains 25 are used, a corresponding number of sprockets 24 are arranged on the rotating shaft 23 of the stepping motor 26. Is done.

A plurality of jigs 1 connected to the loop chain 25 are preferably arranged at step transfer intervals over the entire length of the loop chain 25.
The step transfer interval is the same as the arrangement interval of the apparatus in each step including the cutting parts 4 and 6 and the fusion part 7 of the belt tip part processing apparatus of the present invention. Accordingly, if the belt WB is mounted on the leftmost jig (hereinafter abbreviated as mounting jig 2) in FIG. 2 and then the circulating track type conveyor belt system 8 is operated, the belt WB is mounted. The jig 2 can pass through devices for each process such as the cutting parts 4 and 6 and the fusion part 7 sequentially.

  Further, when the belt WB to be processed is continuously mounted on the mounting jig 2, the entire apparatus of the present invention can process a large number of belts substantially simultaneously in each step such as cutting and fusing. For connecting the loop chain 25 and the jig 1, a general connecting member 27 as shown in the partially enlarged view of FIG. 2 can be used. One side of the connecting member 27 is connected to the loop chain 25 and the other side is connected to the jig 1 so that the connecting member 27 does not come into contact with the sprocket 24.

  The cutting parts 4 and 6 according to a preferred embodiment of the belt tip part processing apparatus of the present invention employ a cutting apparatus using ultrasonic waves. Moreover, it is preferable that the cutting | disconnection parts 4 and 6 are equipped with many ultrasonic cutting devices 4 and 6 so that the belt with which the jig 1 was mounted | worn can be cut | disconnected in multistep.

  For example, as shown in FIGS. 1 to 3, the first ultrasonic cutting machine 4 that cuts a part of the thickness of the belt WB and the first ultrasonic cutting machine 4 are separated from each other by a step transfer interval of the transfer unit. And a second ultrasonic cutting machine 6 that completely cuts the belt partially cut by the first ultrasonic cutting machine.

  As shown in FIGS. 5 and 6, the first ultrasonic cutting machine 4 is installed so as to be moved up and down by an elevating device such as the first ultrasonic cutting machine lower cylinder 31, and the first ultrasonic cutting machine 4 is formed with the protrusion 32. An ultrasonic cutting machine lower block 33 and a first ultrasonic cutting machine upper block 35 installed so as to be moved up and down by a lifting device such as the first ultrasonic cutting machine upper cylinder 34 are included. The first ultrasonic cutting machine 4 includes an ultrasonic generator (not shown). The configuration of the second ultrasonic cutting machine 6 can be configured almost the same as that of the first ultrasonic cutting machine 4, and the description thereof will be omitted (see FIG. 8).

  The first ultrasonic cutting machine 4 having such a configuration intervenes between the protruding part 32 of the first ultrasonic cutting machine lower block 33 and the first ultrasonic cutting machine upper block 35 when cutting the belt. The belt is cut using ultrasonic waves while applying pressure to the belt portion. The first ultrasonic cutter 4 cuts the belt about ½. Since the second ultrasonic cutting machine 6 operates almost the same as the first ultrasonic cutting machine 4, description thereof is omitted. The second ultrasonic cutter 6 cuts the belt completely.

  If the stepping motor 26 rotates one step, the jig 1 on which the belt WB is mounted moves by the step transfer interval and is positioned on the first ultrasonic cutting machine 4. At this time, the leading end of the belt WB is positioned between the first ultrasonic cutting machine block 33 and the first ultrasonic cutting machine upper block 35.

  When the belt WB is inserted between the first ultrasonic cutting machine lower block 33 and the first ultrasonic cutting machine upper block 35, the first ultrasonic cutting machine lower block 33 is moved up and down, for example, the first ultrasonic wave. While being raised by the lower cutter 31, the first ultrasonic cutter upper block 35 pressurizes the belt WB while being lowered by the lifting device, for example, the first ultrasonic cutter upper cylinder 34. The front end portion of the belt WB is cut using ultrasonic waves while being pressed between the protruding portion 32 of the first ultrasonic cutting machine lower block 33 and the first ultrasonic cutting machine upper block 35.

  A device for applying ultrasonic waves, for example, an ultrasonic generator (not shown) can be installed on the upper blocks 35 and 36 of the first ultrasonic device 4 and the second ultrasonic device 6, for example. In addition, as described above, the belt is cut by about 1/2 by the first ultrasonic cutting machine 4 during pressurization.

When the belt WB is cut by about ½, the process in the first ultrasonic cutting machine 4 is finished, and the first ultrasonic cutting machine upper block 33 and the first ultrasonic cutting machine lower block 35 are raised. And descend. In this state, the operator manually activates the control unit 11 as will be described later, or moves the jig 1 by one step by a program input to the control unit 11.
During the process in the first ultrasonic cutting machine 4, the operator mounts a new belt on the mounting jig 2.

  When the belt WB cut by about ½ is transferred to the second ultrasonic cutting machine 6, the second ultrasonic cutting machine upper block 36 and the second ultrasonic cutting machine lower part 37 of the second ultrasonic cutting machine 6. Is raised and lowered, and an ultrasonic wave is applied while applying pressure to the belt WB to completely cut the belt WB.

  As shown in FIG. 7, the belt is cut by the protrusions 32 formed in the first ultrasonic cutting machine lower block 33 and the second ultrasonic cutting machine lower block 37. The protrusion 32 has a shape to be cut. Desirably, the protrusion 32 has a curved shape. Therefore, in the present embodiment, the tip of the cut belt becomes a curve. However, the cutting shape of the belt tip is not necessarily limited to a curved line, and there is no special restriction as long as it can be easily inserted into the buckle B.

  In addition, if the belt WB is cut in two steps in this way, the cut surface is much cleaner than if a thick belt is cut at once. If a thick belt is cut in one step, the cut surface will not be clean due to the thickness, but if this is cut several times, the cut surface can be made very clean.

  Here, the cutting operation using the ultrasonic waves of the first ultrasonic cutting machine 4 and the second ultrasonic cutting machine 6 is started by the operator manually operating the control unit 11 or inputted in advance to the control unit 11. It can be automatically operated by a program.

  The belt tip processing apparatus according to the preferred embodiment of the present invention may further include a cutting site removing device 38 for removing the cutting site of the belt cut by the second ultrasonic cutting machine 6, as shown in FIG. . For example, the cutting site removing device 38 includes a support device 40 that supports the cutting site of the belt, and a support device moving device 39 that moves the support device 40 closer to the support position and moves it from the support position to another position.

  When the belt WB is completely cut by the second ultrasonic cutting machine 6, the cutting site removing device 38 brings the support device 40 close to the belt tip to support the belt tip. Next, when the second ultrasonic cutting machine 6 completely cuts the tip of the belt, the support device moving machine 39 of the cutting site removing device 38 moves the support device 40 backward to remove the cut site of the belt. . As a result, it is possible to prevent troubles such as the cut part of the belt being caught between the movable parts of the apparatus.

  When the end of the belt is completely cut with a curve by the second ultrasonic cutting machine 6, the upper block 36 and the lower block 37 of the second ultrasonic cutting machine 6 are moved up and down, and the belt WB is melted in the next step. It is transferred to the landing part 7.

  As shown in FIGS. 1 and 9, the fusion part 7 is moved up and down by an elevating device such as a cylinder 41, and an upper part of an ultrasonic fusion machine having a protruding pressure part 42 that fixes a belt whose tip is cut. A block 43 and an ultrasonic fusion machine 45 having a fusion groove 44 corresponding to the cut surface of the belt WB are included. The ultrasonic fusion machine 45 fuses the cut surface using ultrasonic waves when the fusion groove 44 contacts the cut surface of the belt. The fusing unit 7 is provided with a fusing machine moving machine such as a cylinder 46 for moving the ultrasonic fusing machine 45 back and forth, and advances the ultrasonic fusing machine 45 to fuse the cut surface of the belt. , Retract after fusion is complete.

  As shown in FIGS. 1 and 2, the belt tip processing apparatus according to the preferred embodiment of the present invention includes a printing unit 14 at the subsequent stage of the fusion unit 7. When the fused belt is transferred by one step, the printing unit 14 prints a desired pattern or phrase on the belt WB. Such a printing unit 14 is configured to be lifted and lowered by using a lifting device such as a cylinder 12, so that the printing plate 13 and the like are lowered to perform the printing work, and after the work is completed, the printing is performed. The plate 13 is raised. The belt that has been printed is transferred to the take-out unit 9 by the transfer unit.

  10A and 10B are views showing the take-out portion 9 of the belt tip end processing apparatus, in which FIG. 10A is a view at the time of contact with the belt WB, and FIG. 10B is a view showing the take-out operation of the belt WB. It is a figure for demonstrating.

  As shown in FIG. 10 (a), the take-out portion 9 is installed at a predetermined height on the frame 10 and a suction pad to which a vacuum device (not shown) is connected so as to suck the belt when in contact with the belt WB. 51, after the suction pad 51 is lowered to suck the belt and sucks the belt, the lifting device such as the suction pad lifting device 49 for lifting the suction pad 51, and the lifting device are moved in the lateral direction. A lateral movement machine such as a suction pad lateral movement machine 47. The take-out unit 9 is installed at the subsequent stage of the fusion unit 7, or in the subsequent stage of the print unit 14 when including the print unit 14, and sucks and takes out the belt WB attached to the jig 1.

  The suction pad 51 is connected so that a vacuum pressure of a vacuum device such as a compressor (not shown) is applied, but is omitted in the drawing. Reference numeral 48 denotes a transfer plate, and 50 denotes a lifting plate.

  When the jig 1 is transferred to the take-out unit 9, the lateral movement machine 47 such as the cylinder 47 is operated to position the suction pad 51 on the upper side of the belt WB. Next, the suction pad 51 is lowered by an elevating device such as the cylinder 49 and comes into contact with the belt, and the suction pad 51 sucks the belt WB by the vacuum pressure of the vacuum device. When the belt WB is adsorbed, the belt WB is taken out from the jig 1 while moving the belt in a direction in which the lateral movement machine 47 moves away as shown in FIG.

  When the belt WB is detached from the jig 1, the vacuum pressure applied to the suction pad 51 is cut off, and the belt WB and the suction pad 51 are separated.

  The belt WB taken out by the take-out unit 9 naturally falls into the storage unit 8 while the jig 1 is step-transferred by the transfer unit. The belt tip end processing apparatus of the present invention includes a storage unit 8 for safely storing the processed belt that has been taken out by the take-out unit 9.

  Moreover, it is preferable that the belt front-end | tip part processing apparatus of this invention contains the belt conveyor part 15 installed so that the site | part of the buckle B of the belt with which the jig | tool 1 was mounted | worn may be supported, as shown in FIG. . The belt conveyor portion 15 has the same height as the jig body 16 and supports the opposite end portion of the belt end portion held by the jig 1, that is, the buckle B, and rotates in the belt transfer direction. In addition, the belt conveyor unit 15 is preferably configured to move at the same speed as the transfer unit by connecting the belt conveyor unit rotation shaft 28 to the rotation shaft 23 of the stepping motor 26.

  As described above, the belt tip end processing apparatus of the present invention includes the control unit 11 for controlling the apparatus for each process.

  The controller 11 of the present invention can include all of manual, automatic, and semi-automatic. In the case of manual operation, the control unit 11 includes at least a switch for controlling the transfer operation of the transfer unit and a switch for controlling the operation of each of the remaining process devices other than the transfer unit. In the case of automatic operation, each of the above-described process apparatuses is controlled automatically by a program inputted in advance.

  Hereinafter, the operation of the belt tip processing apparatus according to the preferred embodiment of the present invention as described above will be described. In the belt tip portion processing apparatus of the present invention, all the belts WB to be processed into a large number of jigs 1 are mounted and sequentially pass through the apparatus for each process. A simplified description of passing through the apparatus will be given.

  First, the operator passes the tip of the belt WB under the cylindrical member 20 of the holding portion 3 of the mounting jig 2, and the belt WB is guided by the second guide member 17-2. Push until the tip is in contact with the first guide member 17-1.

  Next, the buckle B which is the other end of the belt WB is fixed to the belt conveyor unit 15. When the mounting of the belt to the mounting jig 2 is completed, the transfer unit operation switch of the control unit 11 is operated to transfer the jig 1 by one step.

  That is, when the stepping motor 26 rotates by one step, the jig 1 connected to the stepping motor 26 by the sprocket 24 and the loop chain 25 moves by one step. As described above, when the jig 1 moves one step, the attached belt is positioned in the first ultrasonic cutting machine 4 of the cutting unit 4. At this time, the front end portion of the belt WB is fixed between the lower block 33 and the upper block 35 of the first ultrasonic cutting machine 4.

  After the belt WB is fixed between the lower block 33 and the upper block 35 of the first ultrasonic cutting machine 4, the first ultrasonic cutting machine 4 operates. For example, in the case of manual control, the operation of the first ultrasonic cutter 4 is started by the operator operating the corresponding operation switch of the control unit 11, and in the case of automatic control, the step transfer of the transfer unit is completed. Immediately after that, the control unit 11 can be programmed so that the operation is started.

  When the operation of the first ultrasonic cutting machine 4 is started, the lower block 33 is lifted by the lifting device such as the lower cylinder 31, and the upper block 35 is lowered by the lifting device such as the upper cylinder 34, The belt inserted in is cut using ultrasonic waves. Specifically, the projection 32 and the upper block 35 of the cutting machine lower block 33 apply ultrasonic vibration while pressing the tip of the belt WB to cut the portion.

  As described above, it is preferable that the first ultrasonic cutter 4 cuts about 1/2 of the belt thickness.

  When the belt WB is cut by about ½, the process in the first ultrasonic cutting machine 4 is finished, and the upper block 35 and the lower block 33 of the first ultrasonic cutting machine are raised and lowered, respectively. In this state, the transfer unit moves the jig 1 to one step by a switch operation of the control unit 11 by the operator or a program set in the control unit 11.

  During the cutting process of the first ultrasonic cutting machine 4, the operator mounts a new belt on the mounting jig 2.

  When the belt WB cut by the first ultrasonic cutting machine 4 is transferred to the second ultrasonic cutting machine 6, the upper and lower parts of the second ultrasonic cutting machine 6 are the same as the first ultrasonic cutting machine 4 described above. While the blocks 36 and 37 apply pressure to the belt WB, the remaining portions of the belt are completely cut using ultrasonic waves.

  Before the second ultrasonic cutting machine 6 cuts the belt, the cutting site removing device 38 advances the support device 40 to support the site of the belt to be cut. In this state, the second ultrasonic cutting machine 6 operates to cut the belt completely. The cutting site removing device 38 removes the cut site by dropping the cut site to a predetermined position such as a box. As a result, it is possible to prevent an obstacle to the drive part of the apparatus caused by the cutting part.

  Thus, a good cut surface can be obtained by cutting the tip of the belt by two or more steps.

  The raising and lowering operation of the lower blocks 33 and 37 and the upper blocks 35 and 36 of the first and second ultrasonic cutting machines 4 and 6, and the ultrasonic generator 3 are controlled by a program input to the control unit 11. Alternatively, it can be operated by an operator manually operating an operation switch installed in the control unit 11.

  After the tip of the belt WB is cut into a desired shape, for example, a curve, by the second ultrasonic cutting machine 6, the upper and lower blocks 36, 37 of the second ultrasonic cutting machine 6 are moved up and down, and then the jig 1 and the belt WB are moved. It moves to the fused part 7 of the process.

  As shown in FIG. 9, when the belt having the cut end is transferred to the fusion part 7, the ultrasonic fusion machine 45 is advanced by a fusion machine moving machine such as the cylinder 46, and the fusion groove 44. The cut surface of the belt is inserted into the belt. The cut surface of the belt inserted into the fusion groove 44 is smoothly fused by ultrasonic fusion.

  When the cut surface of the belt is fused, the ultrasonic fuser 45 is separated from the belt by the cylinder 46, and the jig 1 and the belt are moved to the printing unit 14, which is the next process.

  The printing unit 14 performs predetermined printing on the belt WB. After the printing on the belt is completed, the belt WB and the jig 1 are transferred to the take-out section 9 which is the next step.

  When the belt WB and the jig 1 are transferred to the take-out unit 9, the suction pad 51 is moved to the upper part of the belt WB by a suction pad lateral movement machine such as the cylinder 47. Next, after the suction pad 51 is lowered by the lifting device such as the cylinder 49 so as to contact the belt WB, the belt is sucked by using the vacuum pressure of the vacuum device.

  In this state, the suction pad lateral movement machine 47 moves in a direction away from the take-out portion 9 and takes out the belt WB from the jig 1 of the jig 1. When the belt WB is taken out from the jig 1, the vacuum pressure applied to the suction pad 51 is cut off, and the belt WB and the suction pad 51 are separated.

In this state, the jig 1 moves one step, and the belt WB is dropped and stored in a separate storage unit 8.
As described above, in the belt tip processing apparatus of the present invention, when the operator operates the control unit 11 after mounting the belt WB on the mounting jig 2, each process is sequentially performed by the control unit 11. The belt tip processing step is automatically performed.

  The configuration and operation of the control unit 11 described above can also be executed from programs and devices used in general automated equipment.
