The patent document 1: Japanese special 1 Λ Λ, « does not match JP-A-2002-10437 [Summary of the Invention] [Problem to be Solved by the Invention] The above-mentioned known strapping machine is used as a tensioning mechanism for tightening a winding mechanism that is wound around a work belt, and therefore the above-mentioned sheet is necessary. There are a number of parts ^ Adjusting rod 24 is a complicated problem. Another 1 force arm; moving the cam mechanism to 1 ^ 2 旋 is rotated by the cam mechanism, therefore:: 疋 moving has a limit and can not freely control the amount of rotation That is, there is a problem that the control of the tension is difficult. "There is a structure in which the tension is tightened: for this reason, it is known to omit the tensioning machine constituted by the above-mentioned tension arm 20 or the like and to make the above-mentioned feed rotor, In the above, the strapping machine is used to make the feed rotor 18 reverse:=: After tightening the workpiece, to the second turn to tighten the belt in the bagging machine, the belt is fed to the rotor 18 and above: The lower adjustment rod 12 rises during the pressing of the belt, and is held by the upper rotor 19 To maintain the tension, it is necessary. That is, the two rotors 18, must be pulled back. The tension is given to the belt so that it is attached to the feeding rotor 18 in such a strapping machine. The retort motor is provided with a brake mechanism to maintain the stop state of the feed rotor 18 during the period from the tension belt to the second lower sag 12 as the dust belt is lifted. - However, as described above, the maintenance belt is pulled back. The motor is stopped at the time of 201134723. The brake mechanism is necessary and the cost is also soaring. The number of parts of the brake mechanism is increased, and the equipment, the object of the present invention is to provide a brake mechanism even if a special tensioning mechanism or motor is not installed. The tight belt does not loosen the 'cost-saving strapping machine. [Technical means for solving the problem] The present invention relates to a strapping machine comprising a belt path wound around a belt to be packed, a feed motor for feeding or pulling the belt, and a belt for pressing and winding the packaged object. The 帛β pressure mechanism on the front end side presses the belt to the front end side, and then presses the second pressing mechanism on the pull-back side, and pushes the position closer to the second pressing mechanism. a dissolving mechanism that dissolves between the overlapping portions of the belt, and a cutting mechanism that cuts off the supply end side from the melting portion of the belt. The second pressing mechanism's dissolving mechanism and the cutting mechanism are provided. The cam 4 camshaft is configured to sequentially rotate the camshaft motor, and the controller for controlling the feed motor and the camshaft motor is provided. The first invention is based on the above-described strapping machine, and the controller is provided with The above-mentioned feed motor pulls the belt tensioning step to detect the current consumption or voltage of the feed motor, and starts when the detected value is set to a predetermined value for driving the camshaft motor. Camshaft motor drive Function and operation of the second pressing means, the pressing means to feed the second operation before the rotation of the motor is stopped. According to a second aspect of the invention, the controller sets a set value of a current or a voltage for stopping the feed motor, and sets the stop set value to be larger than a set value for driving the camshaft motor. 8 201134723 [Effects of the Invention] In the first and second inventions, the belt is tensioned by the feed motor, and the first/lowering mechanism grips the belt supply end side, and the tension is tightened while maintaining the tension (4). The feed motor in the direction rotation stops. Because &, there is no need for the feed motor to maintain the tensioning mechanism of the belt. Therefore, the cost of parts can be reduced compared to the case where a special tensioning mechanism or a brake mechanism of a motor is incorporated. [Embodiment] An embodiment of the present invention is shown below. The strapping machine of the present embodiment does not include the tensioning mechanism composed of the tension arm 2, the passage 2, the tension claw 23, and the adjustment lever 24, and the feed rotor 18 is reversed to tighten the belt. The known strapping machines shown in Figures 3 to 6 are different. Since a structure which is common to a known packing machine is also contained in a large amount, the same components as those of Figs. 3 to 6 are used for the components having the same functions, and the following description will be referred to Figs. 3 to 6 . In the packing machine of the present embodiment, as shown in Figs. 4 and 5, the feed rotor 18 having the forward rotation and the reverse rotation to convey the belt B and the feed rotor 丨8 are rotated upwardly from the upper side of the feed rotor 丨8. The rotor motor 8 is connected to the drive motor (referred to as "feed motor" in the present specification) M11 of the forward/reverse rotors 18 and 19 that supplies, pulls back and tightens the belt as shown in FIG. The rotation of the feed horse causes the feed rotor 18 to rotate forward or reverse. In addition, here, the forward rotation of the feed motor M丨 rotates the belt B in the direction in which the belt guide is turned out, and the so-called reverse rotation means that the belt is wound by the 201134723 on the workpiece W. Rotation in the direction of back and tension.枵,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 7 The heating state 13 in the track or the retreat avoidance, the pressing member 7 for the sliding platform 7, the second lower adjustment lever & the pressing member 4 for moving up and down, and the lower blade 15 are all driven by the cam mechanism. In the first aspect of the present invention, the first T adjusting lever U and the sliding platform 7 constitute a moving mechanism, and the second lower adjusting lever 12 and the sliding + opening constitute a second pressing mechanism of the present invention ( Refer to Figures 4 to 6). Fig. 1 is a view showing the control mechanism of the baggage machine of the present embodiment. The components driven by the cam mechanism are set to cams of the common camshaft 26 and the camshaft 26 is coupled. On the camshaft motor Μ2. Therefore, the cam which is configured to be driven by the camshaft motor M2 to be grayed out causes the above-described members to be horizontally moved at a predetermined timing. Further, the camshaft motor Μ2 is connected to a controller C for controlling the camshaft motor Μ2. In addition, 'FIG. 1 is not intended to be' shown in the above-mentioned camshaft 26 for each member: a cam that drives each member, but in fact, a separate cam can be provided for the driven member, and a common cam drive can be used. Further, the member to be driven is not limited to being directly in contact with the cam provided on the camshaft & the member may be coupled to the cam via a communication mechanism such as a ring. The focus is on the corpse to perform a specific action due to the rotation of the camshaft 20. Further, the controller c is connected to the feed motor M1, and the feed 10 201134723 is coupled to the feed rotor 18 so that the belt 8 can be transported by the controller. However, the feed motor M1 can be rotated in both the forward and reverse directions as described above. The controller C controls the rotation. Further, the controller c has a function of detecting the consumption of the feed motor (4): value 丨. This current consumption value corresponds to the value of the load acting on the feed motor M1, and if the load becomes large, it becomes larger. In addition, the symbol 27 in the figure is a start switch pressed by the operator. The flow of the tape winding by the packing machine of the present embodiment will be described. First, the tape guide 8 is held under the traveling track of the belt as shown in FIG. 4, and the insertion hole 16 of the adjustment rod 11 is opposite to the belt guide. The belt B that is wound around the reel 25 from the above state passes through: The pull phase pulls out 'through the feed rotor 18 and the upper rotor jack 16 and the guide passage 1〇. After the Π insert, the controller c drives the feed motor M1 to rotate the direction of the arrow of the feed rotor 4, and the R R (Fig. 4) belt B is pushed at the belt speed of the curved guide member 5, so that the front end is locked to the belt. The stopper 9 of the guide member 8. At the point of the belt = with the stopper 9 'the controller C causes the feed motor M1 to stop the feed of the belt B. In the above-mentioned stopper 9, the above-mentioned stopper 9 is provided with a detection tape B. A switch (not shown) is stopped based on the detection signal, and the above-mentioned control :: VII. The feed robot 1 and the platform 2, 3 in the curved guide 5, the operator W presses the start button 27. The steps shown in Figure 2 illustrate the steps that follow. In addition, 'this flow 201134723 process diagram display control $ rj μ c< control and each based on the control, controller C's virtual book 丸 丸 ^ ^ ̄ ̄ ̄ ̄ action t processing steps only surrounded by solid lines The steps. In step S1, the operator presses the start button λ ^ 牧 button 27 and the start signal is input to the controller C β ^. After the start signal is input, the cam shaft is rotated by M2 in step S2. After the camshaft is rotated by the wheel glaze motor M2, the camshaft 26 is rotated. The rotation of the cam provided on the camshaft 26 causes the first lower adjustment lever 升 to be raised to grip the portion 11a and slide. The platform 7 holds the belt Β (step S3: the shaft % continues to rotate, and the belt guide 8 is retracted from the belt traveling trajectory at the end of the above-described gripping belt B (step S4). At step S5, at the belt guide 8 The controller c first stops the camshaft motor M2 from the timing of the retraction of the traveling path. Next, in step S6, the controller C reverses the feed motor M1 to reverse the feed rotor 18 in the direction of the arrow of FIG. The tape B is returned. As a result, the tape B is forcibly separated from the tape path 6 and wound around the workpiece w. Even if the tape B is wound around the workpiece w, the rotation of the feed motor is not stopped, so the tape B is further pulled back. Thus, the feed motor M1 pulls the belt B back to the tension. In the step of reversing the feed motor M1 to tighten the belt B as described above, the controller C monitors the consumption current value of the feed motor M1. The controller c sets the consumption current value Im| which is input from the feed motor Μ1 as the arrow of the broken line shown in FIG. The set value 11 is compared with 'determining whether the current consumption value 1 has reached the set value L. In step S7', at the above-mentioned current consumption value ιΜ, the field 12 of the set value 丨| is reached, and the current consumption value is at (4) S8. The field D that has not reached the set value of work 1 maintains this state. That is, the feed motor mi continues to reverse, and the camshaft motor M2 is still in a stopped state. Since the above-mentioned current consumption value Im is corresponding to the action on the feed Since the magnitude of the load of the motor Μ ^ is large, the load becomes large. Since the feed motor M1 # is reversed in step S6, the tensioning operation of the belt β is performed in step s7. While the belt B around the workpiece w is still slack, no load acts particularly on the feed motor M1, but if the belt b is tightened, the negative is large, that is, the controller c can monitor the belt with the above-mentioned current consumption value ιΜ1. Tightening state. The current consumption value S8 of the feed motor Μ 1 advances, and after the cam shaft is again retracted, the belt B is fully tightened.

The wheel axle 26 is stopped in a state where the belt guide 8 is retracted from the traveling locus of the belt in the above-described step S4. However, after the rotation is started, the second lower adjustment lever 12 is raised by the wheel in step S9. . In this state, the belt B of the winding W is pressed by the first lower adjustment lever Η and the second lower adjustment lever 12 to maintain the tension of the kidneys η & nw, ^, 〜, the leading end portion of the belt in the delivery direction and the root portion thereof. The parts are opposite to each other and are spaced apart from each other. When it is determined that the current consumption value of the feed motor Μ1 has arrived, the process proceeds to step S11, and if the controller c reaches the set value 12 in step S10', the motor Μ 1 is stopped. The set value value ' is a drive camshaft 13 that is compared with the current consumption value IM1 in which the feed motor M1 is stopped in the present invention in step 12, 201134723. Therefore, the belt B is pulled back by the second lower adjustment lever 12 B. The load of the feed motor M1 is set to the set value i of M2, which is a large value. After the pressing, it is detected that the feed motor M1 is stopped after the belt is further enlarged. As described above, while the feed motor M1 continues to be tightened, the second lower adjustment lever 12 is raised by the cam to press the belt B. 2 Lower adjustment lever 12 keeps the tension of belt B. 〃In addition, the 'feed motor' should be adjusted in the second step. #12 Press the belt B to make it stop. [U can set the stop timing of the feed motor M1 based on the rotation start of the camshaft motor M2, and also the above steps si〇 . After the feed motor is stopped in the above-described step S11, the cam shaft 26 continues to rotate by the camshaft motor M2. In step S12, the heater U which is energized and heated by the cam is moved between the upper and lower facing belts B. The heater 13 then contacts the strip B' and its surface melts. After the surface of the belt B is melted, the heater 13 is retracted from the belt B by four wheels (step S13). Thereafter, in step S14, the pressing member 14 presses the melted portion of the belt B by the cam to ascend, and then the belt B is pressed. At this time, it is assumed that the knife 15 is also raised when the yak 14 is pressed. Therefore, the belt B is cut off together with the knife 17 formed on the jack in step S15. After the belt B is cut as described above, the slide platform 7 is retracted from the traveling path of the belt by the cam in step s16. At step S17, the controller C stops the camshaft motor M2. As described above, the winding operation of the workpiece W is finished. Further, in the above-described embodiment, the controller c detects that the feed motor Μ 1 201134723 is set to the set value I, and replaces the current consumption value Im 1 of the current consumption value, and the current value is 丨 but can be detected.

As described above, the strapping machine of the present embodiment can raise the second lower adjustment lever 12 by the cam in the step S9 while the urging motor M is continuing the tightening operation, and the pressing belt can be the second. The lower adjustment lever 12 maintains the tension state of the belt B, so that it is not necessary to hold the tensioning bear of the belt B when the feed motor M1 is in a stopped state, that is, even if the brake motor is not provided in the feed motor M1, the belt will not loosen. As described above, the packing machine of the present embodiment can not only omit the braking mechanism of the above-described known tensioning mechanism 'feeding motor Μ1, but also reduces the number of complicated structures or parts and accordingly reduces the manufacturing cost.
