Description

Strapping machine

The present invention relates to a strapping machine, and more particularly to a baler construction applied to a bale of a package.

According to the conventional strapping machine, the heart component is mainly composed of a plurality of cams which are driven by a mandrel, and which are driven by a motor, and each of the cams corresponds to a component of a bundle of movements, and the member includes the upper pallet and the heating. , the left knife, the middle knife and the right knife, etc., through the motor to drive the rotation of the mandrel, to control the corresponding control of the upper plate, the heater, the left knife, the middle knife and the right knife, etc. action.

However, the baggage machine used in this description occupies a considerable space in the machine table, and the action of the cam transmission mechanism is single, and since the components of each cam are designed to be eccentric, vibration will be generated during transmission. Moreover, the cam and its corresponding follower generate noise due to the impact during the transmission, and the cam is hardened when it is manufactured, so it has difficulty in the production, and the components of the heart component are controlled by the cam. When it is necessary to have precise control, the cam must have a relatively large size and it is not easy to make.

In addition, the conventional heater 9 shown in FIG. 15 is mainly constructed with an insulating sheet 91 coated on the outer layer of the electric resistance 90, and the electric resistance 90 covered in the insulating sheet 91 is accommodated in a copper layer. 92, the copper layer 92 extends toward the strap 93 in a heating section 920. The heating section 920 is at a distance from the electric resistance 90, that is, the electric resistance 90 is outside the heating section 920 instead of the heating section 920. Therefore, in the process of conducting the heat source of the electric resistance 90 to the heating section 920, the heat energy is inevitably lost due to the distance, thereby causing waste of energy.

Moreover, the strapping machine is maintained in a bare state, so the temperature is lost quickly, but under the requirement of maintaining the heating and melting temperature, the relative thermal energy loss is generated, resulting in waste of energy; in addition, due to the temperature around the heater High, so the mechanical components around the heater will absorb the thermal energy of the heater, and the mechanical components thus form thermal expansion and contraction, which easily causes the machine of the strapping machine to malfunction.

Therefore, the strapping machine that utilizes the transmission mechanism of the cam has the above problems, and how to solve such problems is the focus of the present invention.

One of the objects of the present invention is to solve the above problems and to provide a strapping machine, wherein the components of the cardiac component are simple and easy to manufacture, the volume of the cardiac component can be relatively reduced, and the manufacturing cost can be relatively reduced, and the cam is not eccentric when actuating. Rotation and impact can avoid noise and vibration.

The second object of the present invention is that the heating element of the heater is directly extended into the heating section, so that the heating element can conduct heat to the heating section at a short distance, so that the heating section can be directly heated without being subjected to comparison. Long heat conduction distance causes thermal energy loss, and the heater is normally in the melt zone, and when the strap must be melted, the heat insulation sleeve is pulled out to expose the heating section, and the linkage mechanism is used to drive the cam time. The mechanism has a long relationship, so that the time for melting the strap and the exposed heating section can be relatively increased, so that the set temperature of the heater can be relatively lowered, and the heating section of the heater is insulated by the non-melting strap. The coating can also reduce the heat energy loss of the heater, thereby avoiding waste of energy, and by the heat insulation of the heat insulating sleeve, the heat absorption of the components around the heater can be avoided to cause the bundler to malfunction.

For the purposes of the foregoing, the present invention includes:

a workbench, a bundle of tape reel and a heart component, the workbench has a platform, and the workbench has a track guiding the strap path, and a feeder and a retractor are arranged in the middle of the track, the heart The assembly is provided at the end of the track for the fusion zone and the cutting tape.

The connecting rod mechanism drives the upper sliding plate to laterally slide and Longitudinal sliding of the longitudinal slide;

a rotating member is disposed on the upper pushing plate and intermittently rotates as the upper sliding plate slides back and forth;

When the upper plate is intermittently rotated, the upper push plate is controlled to swing back to pull the upper plate out of the melt zone, and the upper push plate is controlled to push outward and then push the upper plate back to the melt zone;

a heater correspondingly has a heating section in the melting zone, and is slidably sleeved outside the heater by a heat insulating sleeve, and the heater is pulled out of the melting zone by the upper sliding plate, and the heat insulating sleeve is Push the heater back into the melt zone when extrapolating;

Between the head section 210 of the 21 and the upper section of the tail section 211, the upper pallet 6 is positioned above the head section 210 of the strap 21, and the pressure plate 53 is located below the tail section 211 of the strap 21.

When the head section 210 and the tail section 211 of the strap 21 are to be melt-bonded in the melt zone 43, the drive mechanism 52 first drives the link mechanism 5 to swing forward for the first time to drive the retracting disc group. 8 is actuated, that is, during the rotation of the first circle 80, the second disk 81 is intermittently rotated by one third of a turn, and the second disk 81 is rotated by one third of a turn. The third disk 82 is intermittently rotated by one-half turn, and as shown in FIG. 13-2, the swing arm 83 pulls the heat insulating sleeve 71 out of the melt zone 43 to heat the heating section 70 of the heater 7. Exposed; while the link mechanism 5 swings forward for the first time, the rotating member 54 moves to the first blocking portion 461 in the notch 460 by the position of the second blocking portion 462 as the upper sliding plate 51 slides. In this position, as shown in FIG. 14-1, a rib 540 on the rotating member 54 will touch the first blocking portion 461 to drive the rotating member 54 to rotate a sixth turn, so that the lower blocking portion 542 is rotated. Forward, and the lower stop 542 corresponds In the second hook 72 of the engagement protrusion position.

As described above, when the heating section 70 of the heater 7 is exposed, the link mechanism 5 is also swung forward for the first time to drive the upper pedal 51 to slide forward, and the longitudinal slider 50 is then Sliding upward, the pressing plate 53 first pushes the tail section 211 of the strap 21 toward the bottom of the heating section 70, and the top of the heating section 70 pushes the head section 210 of the strap 21 to the extrusion. At the bottom of the upper pallet 6, as shown in Fig. 13-3, at this time, the head section 210 and the tail section 211 of the strap 21 are in contact with the heating section 70 to be melted, and the first inlet port is utilized. The upper surface 40 of the 40 is cut by the end edge 530 of the pressure plate 53 to shear the strap 21 .

After the head section 210 and the tail section 211 of the strap 21 are in contact with the heating section 70 to be melted, the link mechanism 5 is swung for the first time with the driving motor 52, at the time of the front. The push plate 51 will be driven by the link mechanism 5 to slide backward, and when sliding backward as shown in Fig. 10, the second projection 72 on the heater 7 is hooked by the front lower stop portion 542. The heater 7 is hooked away from the melt zone 43 as the upper push plate 51 slides backward as shown in Fig. 14-2, at which time the heat insulating sleeve 71 has stayed behind and the heater 7 is heated. When the segment 70 is retracted, it is retracted into the heat insulating sleeve 71, and as shown in Fig. 13-4, the packing tape 21 has no barrier between the head portion 210 and the tail portion 211 in the melt zone 43 at this time.

The lower stopper portion 542 swings to the side, and the lower stopper portion 542 is disengaged from the second projection 72.

After the heater 7 is driven backward by the upper push plate 51, the link mechanism 5 swings forward a second time, at which time the pressure plate 53 moves up with the longitudinal slide 50 as shown in FIG. 13-5. The pressing plate 53 drives the head section 210 and the tail section 211 which have been melted by the packing belt 21 to be stacked and pressed against the bottom of the upper pallet 6 to be joined. While the link mechanism 5 swings forward a second time, the rotating member 54 moves to the position of the first blocking portion 461 in the notch 460 by the sliding of the upper pedal 51 and the position of the second blocking portion 461. When the rib 540 of the rotating member 54 touches the first blocking portion 461 and drives the rotating member 54 to rotate a sixth turn in the same direction, the upper blocking portion 541 is turned toward the second blocking portion 541. The upper portion 541 corresponds to the hooking position of the first bump 60 at the bottom of the upper tray 6.

When the combination of the head section 210 of the strap 21 and the tail section 211 is completed, as shown in Figs. 7 to 8, the rotating member 54 on the upper pedal 51 hooks the upper pallet with its front upper stopper 541. 6 at the bottom of the first bump 60, at this time, the upper push plate 51 will swing back with the link mechanism 5 for the second time, and the upper pallet 6 will be dragged back, at this time due to the head section 210 of the strap 21 The tail section 211 has been combined, and as shown in Figures 13-6, as the upper pallet 6 is pulled back and tightened to the bottom of the package A, the wrapping operation of the package A is completed, and the rotating member 54 is as above. The push plate 51 slides backward, and in the notch 460, the position of the first stop portion 461 is restored to the position of the second stop portion 462. At this time, as shown in FIG. 14-4, the rotating member 54 is The other rib 540 touches the second blocking portion 462 to drive the rotating member 54 to rotate in the same direction for one-sixth turn. At this time, the upper blocking portion 541 is swung to the side, and the upper blocking portion 541 is disengaged from the first The bonding of the bumps 60.

Then, the link mechanism 5 swings forward a third time, and the upper pallet 6 is pushed forward again by the upper pushing plate 51, and the first disc 80 is intermittently driven during the third rotation. The second disc 81 is rotated by the last third turn. At this time, during the last third turn of the second disc 81, the third disc 82 is intermittently driven to rotate the last half turn. The swing arm 83 brings the heat insulating sleeve 71 back to the ribbon zone 43, and the heater 7 is forwarded with the heat insulating sleeve 71 to return to the initial position of the ribbon zone 43, and then the link mechanism 5 goes to the third time. The rear swing is performed, and as shown in Figs. 13-7, the initial position of the front member 210 and the tail portion 211 of the strap 21 are melted and combined to complete the assembly operation.

While the link mechanism 5 is swinging forward for the third time, the rotating member 54 is also moved to the position of the first blocking portion 461 in the notch 460 by the position of the second blocking portion 462 in accordance with the slip of the upper pedal 51. At this time, as shown in FIG. 14-5, one of the ribs 540 of the rotating member 54 will touch the first blocking portion 461 to drive the rotating member 54 to rotate for one-sixth of a turn; the link mechanism 5 is at the third position. Simultaneously, the rotating member 54 also slides backward with the upper pedal 51, and returns to the position of the second blocking portion 462 in the notch 460 by the position of the first blocking portion 461. As shown in Figures 14-6, the other rib 540 on the rotating member 54 touches the second blocking portion 462 to drive the rotating member 54 to rotate in the same direction for one-sixth turn; the third in the link mechanism 5 When swinging forward and backward, the rotating member 54 does not drive the upper pallet 6 or the heater 7 to be displaced, but only follows the upper pedal 51 to move back and forth.

It is not difficult to find the advantages of the present invention by the above description in that:

1. The strapping machine of the present invention mainly uses the reciprocating swing of the link mechanism 5 to drive the upper pallet 6, the heater 7 and the retracting disc group 8 to operate according to the timing of the arrangement, relative to the conventional bundle. The charter machine replaces the cam with the link mechanism 5, and the space occupied by the link mechanism 5 in the heart component 3 can be smaller than the space occupied by the cam, so the heart component 3 of the present invention has a reduced volume relative to the conventional heart component. The advantage is that when the heart assembly 3 of the present invention is installed on the worktable 1, more space can be vacated in the worktable 1, which has great advantages for mechanism design and function expansion.

2. The strapping machine of the present invention mainly utilizes the linkage mechanism 5 to operate, and since there is no vibration problem due to eccentricity when the cam is driven, the vibration can be relatively reduced to avoid component damage, and there is no cam and the follower. The problem of noise due to impact can be relatively quiet when the operation is performed, and the components of the cam are not required, so that the problem of the difficulty in manufacturing the cam and the size of the cam can be avoided, and the manufacturing cost of the strapping machine can be reduced.

3. The package of the present invention, wherein the heating element 73 of the heater 7 extends over the heating section 70. The heating element 73 of the present invention shows that the heating element 73 of the present invention conducts heat to the heat conducting layer 75 at a shorter distance than the conventional heater. The heat loss caused by heat conduction can be reduced, and the waste of energy can be avoided; in addition, during the packing operation of the heater 7, the heating section 70 is only in the head section 210 and the tail section 211 of the strap 21 It is exposed during melting, and is covered in the heat insulating sleeve 71 for the rest of the time. Compared with the heater of the conventional strapping machine, the heat dissipation of the heating section 70 can be prevented from continuing to disperse by the heat insulation of the heat insulating sleeve 71. Thereby, the heat energy loss of the heater can be reduced, and by the heat insulation of the heat insulating sleeve 71, the heat absorption of the components around the heater can be avoided, and the problem that the baler does not absorb heat can be ensured.

The above description of the embodiments is intended to be illustrative of the invention and is not intended to limit the scope of the invention.

From the above detailed description, it will be apparent to those skilled in the art that the present invention can achieve the foregoing objects and is in accordance with the provisions of the Patent Law.
