Description

Automatic strapping machine

technical field

The utility model relates to a binding machine, in particular to an automatic binding machine for paper printed matter.

Background technique

With the increasing abundance of various commodities in our country, the requirements for commodity packaging are also increasing, so that the printing and die-cutting machinery of trademarks and the automatic packaging machinery of commodities have developed rapidly. However, the automatic strapping machinery for trademarks has not been effectively broken through and has become a major bottleneck in the packaging industry. Traditional trademark bundling is often done by hand, or the stacked trademarks are manually wrapped with plastic wrapping film, or the stacked trademarks are manually wrapped with kraft paper and then pasted with adhesive tape (glue). The production efficiency of its manual binding is extremely low; the quality of the binding is poor, and the trademark is easily damaged; In short, it is time-consuming, time-consuming, and poor in quality to manually bundle trademarks, and it is not suitable for use on automatic commodity packaging machines.

After the efforts of colleagues in the same industry, a trademark binding machine was developed. The main action of the strapping is realized by the mechanism of the cylinder linear unit. The disadvantages of this strapping machine are: first, the production efficiency is low, and the strapping is realized by several cylinder linear unit mechanisms in the three-dimensional space of X, Y, and Z. Each step of the action, its each step action is that the cylinder linear unit mechanism of the next step action can start to act after the cylinder linear unit mechanism completes the step action and returns. That is to say, it takes a long time to carry out each step in the binding, so the production efficiency is low. The second is that there are many detection points. The action of the linear unit mechanism of each cylinder is based on the detection signal after the previous step action returns to start the step action. Once a certain detection point fails, it is very easy to cause a collision and cause equipment accidents. The third is the high maintenance cost, the frequent reciprocating impact of the cylinder, the device is prone to fatigue damage, and the machine is often shut down for maintenance and replacement of parts. The 4th, production noise is big, and the mechanical noise that cylinder impact produces and the gas noise that cylinder exhaust produces is unfavorable for operator's physical and mental health.

In addition, there are trademark strapping machines imported from abroad, and the main actions of the strapping are all driven by servo motors. The performance of the strapping machine is improved compared with that of the cylinder-driven strapping machine. Since the start and stop of each motor have a reaction time, there is still a phenomenon that the production efficiency is not high. Furthermore, the cost of the equipment is relatively high, including the manufacturing cost and maintenance cost of the equipment. There are also difficulties in debugging and maintenance.

Fig. 6 is a schematic diagram of the working principle of the automatic binding machine of the embodiment of the utility model. In order to clearly illustrate the operation process of the utility model, in this embodiment, the X axis is the horizontal direction, the Y axis is the vertical direction, and the Z axis is the vertical direction. The direction of the X and Y axes.

Take the bundled height of 500 trademark stacks as an example:

Driven by the variable frequency motor reducer 5, each cam mechanism converts the selective motion of the circle into a linear motion in the X direction (or Y direction, Z direction). If there is a trademark in the working area of each cam mechanism, the The trademark enters the next step of the work flow in sequence according to the process flow, and each cam mechanism rotates according to a preset phase, so that each component connected to the cam mechanism can perform linear reciprocating motion according to a preset distance.

The first cam mechanism 9 rotates according to the pre-designed phase, and when the lifting tray 10 is driven to move downward ↓ along the Y direction to the lowest point (at this time, the lifting tray 10 and the belt conveying mechanism 8 are basically on the same level), the first photoelectric switch 39 is blocked by the lifting tray 10, and the blocking signal is detected, the second magnetic powder clutch 7 is controlled to engage, and the belt conveying mechanism 8 is driven to run, and the trademark stack is transported to the lifting tray 10 in the left direction along the X direction.

Then the sixth cam mechanism 17 rotates according to the pre-designed phase, drives the cutting knife 15 to move backward ↗ along the Z direction, and cuts off the strapping strap 28 after ironing, so that the bundled trademark stack and the strapping strap 28 after ironing and bonding are combined with each other. The strapping 28 of the constant tension unwinding 27 is separated, and the end of the strapping 28 cut off by the cutter 15 is adsorbed on the negative pressure mechanism 23, so as to realize the winding of the next trademark stack and reserve a certain amount for the binding of the next trademark stack. Length of strapping 28.

After completing the ironing of the strap 28, the seventh cam mechanism 26 rotates according to the designed phase, drives the push plate 25 to move backward ↗ along the Z direction, and pushes the bundled trademark stack (ie product stack) to the bid receiving mechanism twenty four.

As another embodiment of the present invention, the bid receiving mechanism further includes a first product sorting mechanism 29 moving rightward along the X direction and a second product sorting mechanism 30 moving backward along the Z direction.
