[0001]

[Technical field to which the device belongs]

  The present invention relates to a band control device for a strap machine.

[0002]

[Prior art]

  The conventional band control device of a kind of strap machine is as shown in Figs. In addition, the balance rod 11 and the push rod 12 are separately fixedly attached to both ends of the rotary shaft 13, and the rotary shaft 13 is It passes through the separating plate 21 of the band chamber 20 and pivots with the shaft sleeve on the outside of the separating plate 21. It is assembled. The balance rod 11 is inside the separator 21, and the push rod 12 is the separator 2. 1, the shaft sleeve 14 is fitted to the fixed seat 15. Fixed The seat 15 has a support rod 151 extending outward on one side, and the support rod 151 is attached to the right side surface of the support rod 151. The icro switch 16 is fixedly attached, and the front end surface of the icro switch 16 is twisted onto the 152. A lock 17 and a stop rod 18 are provided. The torsion spring 17 is a hook 1 extending downward. 71 is formed on the support by the bottom surface of the rod 151 and further extends horizontally from above. A holding portion 172 is formed to receive the end of the holding rod 12 thereon, and the holding rod 12 is directly attached. The contact button 161 of the micro switch 16 is prevented from being touched.

[0003]   Next, the control system of this conventional band control device 10 is as shown in FIGS. As shown in 5, the band guider 40 is first activated to balance the band 30. Guide along the top end of the rod 11 into the band chamber 20 and fold it left and right in order. Raise upwards. At this time, the weight of the band 30 in the band chamber 20 and the folding up and down If the weight of the sum of the tension of the bent portion is larger than the elasticity of the receiving portion 172, the balance rod 1 1 receives the force and inclines downward, so that the rotary shaft 13 also holds the holding rod in the same step. Hold down 12 and lean. Therefore, the end of the push rod 12 has a receiving portion 17 for the spring 17. Press 2 down to directly contact the rear button 161 of the micro switch 16 to turn it on. Let The microswitch 16 then sends a signal to power the band guider 40. When the band is cut, the band 30 is stopped and cannot enter the band tank 20. Complete the operation of saving the band in the band. On the contrary, it is stored in the band room 20 When the band 30 is pulled out and tied to the carton etc., it is on the balance rod 11. Force disappears, the elasticity of the receiving portion 172 is restored and the push rod 12 is pushed upward. Then, since it is separated from the push button 161 of the micro switch 16, the micro switch 16 simultaneously outputs signals to turn on the power of the band guider 40, The guider 40 again introduces the band 30 into the band chamber 20 and stores the band 30 for the next call. Wait for the binding of an object such as ton.

[0004]

[Problems to be solved by the device]

  The conventional band control device 10 described above utilizes the elasticity of the torsion spring 17. Then, the length of the band stored in the band tank 20 is controlled. So When the trap machine is used, the holding rod 12 receives the torsion spring 17 for a long time. The part 172 is pressed up and down and released. Therefore, the torsion spring 17 is long When used, its elasticity gradually weakens, and in the worst case, it is damaged and cannot be used. Ba Insufficient control of the length stored in the room 20 Situation occurs. Therefore, the band binding work of the carton etc. is not operated smoothly. Become Besides, the elasticity of the torsion spring 17 is constant and cannot be adjusted. Therefore, the setting of the length of the band in the band chamber 20 is controlled by the torsion spring 17 And the band control device 10 cannot adjust the band reserve. It is impossible to handle the actual banding work.   The purpose of the present invention is to provide a strap machine band controller with adjustable band storage. To provide a roll device.

[0005]

[Means for Solving the Problems]

  In order to solve the above problems, the strap machine band according to the claims of the present invention The control device is a torsion sprinkle, which is a drawback of the conventional band control device. Remove. Instead, connect a balance weight and a balance rod to each side of the band chamber. Using this principle, the balance weight and the balance rod are separately connected to both ends of the rotating shaft. The length of the band stored in the band chamber when this rotary shaft is installed with the band chamber facing sideways. It is adjusted and stored so that the size (that is, weight) is optimized. So different sizes It is possible to support objects such as cartons that tie up the band that is O of the band guider which arranges the sensor switch appropriately and introduces the band into the band chamber. It is possible to control N and OFF and stop when the band enters the band room appropriately. And start.

[0006]   Since the weight of the balance weigher can be adjusted freely and the total weight of the balance can be adjusted, The resistance to the balance rod can be increased or decreased so that it can be stored in the band chamber. The length of the existing band can be adjusted. So the support of the object that binds the band Adjust the length of the band according to the size. The sensor rod and sensor switch The intelligent action controls the ON / OFF of the band guider to ensure that the band is appropriate When it is stored in the band room, it will operate and The length can be optimally stored in the band room.

[0007]

[Embodiment of device]

  Embodiments of the present invention will be described below with reference to the drawings.   The band control device 60 of the strap machine of the present invention is shown in FIGS. As shown, the band chamber 50, the balance rod 61, the rotating shaft 62, the shaft sleeve 63, Combined with sensor rod 64, balance weight 65, and sensor switch 66 It

[0008]   The band chamber 50 includes an isolation plate 51 and a lid plate 52, which are assembled to face each other with a predetermined space therebetween. Formed together. The separator plate 51 has a hole 511 in the lower portion on the right side of the separator plate 51. A plurality of small holes 512 are provided around the. The balance rod 61 has a predetermined length and It is installed horizontally in the stand tank 50.

[0009]   The rotating shaft 62 has its front end firmly connected vertically to the end of the balance rod 61, and the other end of the rotating shaft 62 is separated. Form a connecting shaft step 621 that extends outward through the hole 511 of the separating plate 51 and has a thread. Is made. The shaft sleeve 63 is a cylindrical body, and is separated by the four screws 67. After passing through the small hole 512, the outer surface of the separator 51 is screwed and fixed. Axis three The hub 63 has a shaft hole 631 at the center thereof and has the same axis as the hole 511. Is inserted into it and pivotally connected, and the connecting shaft step 621 of the rotary shaft 62 is placed outside the shaft hole 631. It extends to the side.

[0010]   The sensor rod 64 has a lateral fitting hole 641 formed at one end, and the fitting hole 61 is formed. 41 is screwed onto the connecting shaft stage 621. The sensor rod 64 has a predetermined length. However, it is installed in the same direction as the balance rod. The balance weight 65 is a weight rod 651 and a weight. 652, and one end of the weight rod 651 is formed with a fitting hole 653. It fits tightly with the connecting step 621. Secure the weight rod 651 to the connecting shaft 621 with the screw 67. Assemble well. At the same time, the weight rod 651 is installed in the direction opposite to the direction of the balance rod 62. The rotary shaft 62 serves as the central fulcrum of the pivotal connection therebetween. Weight 652 fits It has a hole 654 and is fitted to the outer end of the weight rod 651. The weight 652 is Has a horizontal screw hole 655 communicating with the hole 654, and the weight 652 is weighted with the screw 656. Screw it firmly onto the rod 651.   As the sensor switch 66, a proximity sensor is used in this embodiment, and a sensor rod 64 is used. The sensor unit 661 is fixed on the side opposite to the sensor rod 64. Formed to sense the motion of the sensor rod 64.

[0011]   Next, the operation of each part will be described with reference to FIGS. Band guider 70 When the band is activated, the band 80 is introduced into the band chamber 50, The weight of the stored band 80 is larger than the weight 652 of the balance weight 65. The band 80 tilts the balance rod 61 downward. At this time, the balance rod 61 turns By interlocking the rolling shaft 62, the sensor rod 61 is tilted downward and displaced in the same step. B On the contrary, the head 651 tilts upward. The position where the sensor rod 64 is displaced as described above. On the other hand, when the sensor unit 661 detects it, it outputs the detection signal and the band. The power of the guide 70 is cut off, and the introduction of the band 80 into the band chamber 50 is stopped. , Complete the band saving operation of the band room.

[0012]   On the contrary, as shown in FIGS. 8 and 9, the band 80 stored in the band chamber 50 is When the object is pulled out and bound to an object such as a carton, the band 80 moves down the balance rod 61. Since the force of pushing to the end disappears, the weight rod 651 automatically descends to the original position. Returning to the position, the balance rod 61 and the sensor rod 64 are also moved upward by the rotation of the rotary shaft 62. Move and turn to the original position. At the same time, the sensor rod 64 is farther from the sensor unit 661. Since they are separated from each other, the signal sensed by the sensor unit 661 is also interrupted. So sensor sui For that purpose, the switch 66 turns on the power of the band guider 70, and the band 80 is turned on. It is stored in the room 50 and waits for the next work.

[0013]   Then, referring to FIG. 11, the weight 652 is automatically positioned on the weight rod 651. It is adjustable, and if the weight 652 is placed closer to the rotary shaft 62, Since the distance of the force arm to the central fulcrum becomes shorter, the relative resistance between the balance rod 61 and The power becomes smaller. On the other hand, if the weight 652 is located farther from the rotary shaft 62, , The force arm between the central fulcrum also becomes long, so the relative drag force with the balance rod 61 is also large. I hear Therefore, the length of the band 80 in the band chamber 50 is longer than the stored length. And its weight increases. And when the size of an object such as a bound carton changes The operator may adjust the position of the weight 652, and the band in the band chamber 50 may be adjusted. The length of the strap machine makes it possible to match the needs and tension of the strapping machine The process goes well.

[0014]   Further, the present invention utilizes the relative acting force between the balance weight and the balance rod, By combining the sensing function with the sensor switch, the van stored in the band chamber Effectively control the length of the code. At the same time, there is a kind of balance between the balance weight and the balance rod. The lever structure is used, and elastic fatigue and failure resulting from it may occur during use. And no longer. Therefore, the maintenance and repair work necessary for that are not necessary, and the use of the machine The service life is extended. In addition, the length of the band stored in the band chamber is stable and accurate. It becomes possible to promote the whole technology of the machine.
