The present invention relates to an apparatus for inserting a wrapper in which a wrapper is formed at the junction of a product when the product is packaged as an automatic packaging machine, and in particular, in order to sequentially transfer the fabric of the wrapper provided to pack the product. Lay the insert rods with elasticity elasticity on the left and right sides of the chain to face each other and wait. After inserting the rods from the left and right ends toward the wrapping paper located at this point, hold them tightly while forming a curl. Thereafter, both ends are joined together by a jointer, and at the same time, it provides a wrapper inserting device for cutting individually.

Conventionally, as a means for joining the product of the wrapping paper fabric in a predetermined shape in the automatic packaging machine, the chain is formed at both ends and the conveying belt is formed by the conveying belt formed between each chain and the chain is conveyed in the state placed on the wrapping paper, Both ends of the wrapping paper are bonded to each other by the formed upper bonding machine and are transferred to the bonding section in this state, whereby bonding and cutting are performed. In the bonding section, the connecting rod having a high heat and the rotating rod having the cutting knife rotate one rotation to join the central portion of the wrapping paper. At the same time, it has been cut and processed so that the finished product can be put in a wrapping paper.

However, such a bonding simply presses the upper part of the wrapping paper and the cutting knife properly, so that the product is packaged, and only a small amount of the product is packed in proportion to the size of the wrapping paper, resulting in unnecessary waste of the wrapping paper. It is packaged as a wing and occupies the upper space when loaded, and in the case of rectangular products, it was very difficult to pack.

Recently, in order to solve the above problems, a device for forming a curl at the bonding and cutting portions of the wrapping paper has been devised, but since such a device is very large in size and is composed of many complex devices, the factor of increasing the price of the product In addition to the inherent drawbacks, there is a drawback that it cannot be used in addition to a conventional machine.

Therefore, the present invention was devised to solve the above problems, and the curved bar is formed on the lower part of which the rotary bar is fixed, and the insertion rods which are indented and operated by the protrusions are connected to both ends of the chain of the transfer belt. When it is transported along the chain and positioned at the lower part of the rotating rod, both insertion rods are advanced by the curved protrusion to press the side of the wrapping paper, and in this state, the connecting rod and the cutting knife of the rotating rod can join and cut the wrapping paper. It is possible to pack a large amount of products even in a small sized package, to easily package rectangular products, and to be easily mounted on any machine.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing the configuration of the present invention, Figure 2 is a perspective view showing the overall assembled state of the present invention. And (a) and (b) of Figure 3 is an explanatory diagram showing the operating state of the present invention. A plurality of transfer rods 2 are pivotally formed between the chains 3 at both ends of the transfer belt 1, and the rotary rod 4 on which the joint 5 and the cutting knife 6 having high heat resistance are mounted is provided. In the packaging machine for wrapping the product by the joint portion by joining and cutting the central portion of the wrapping paper while appropriately rotating, a protrusion in which the corners are rounded to the bottom of both ends of the rotary rod (4) fixed to the junction to protrude constantly (11) is coupled, the wheel 15 is constructed so that the chain (3) of both sides of the conveying belt (1) is idling each other, the other end of the wheel (15) to the spring (16 ') provided therein Insertion rods 13 receiving elastic force so that they can be fully stretched by each other are coupled to each other to face each other, and are conveyed by guides 14 fixed to the chain 3 and received by the elastic force of the spring 12. It consists of (12).

Reference numeral 20 denotes a wrapping paper fabric, and 21 denotes a completed wrapping paper state.

Looking at the operation and effects of the configuration as described above are as follows.

4 is an exemplary diagram for explaining the third drawing in more detail. When referring to the drawing, the chain 3 of the conveying belt 1 is always provided by a separate driving means (not shown). In the transfer to the junction holding the fixed position, the wrapping paper fabric 20, which is provided for wrapping the product on the transfer rod (2) on the chain (3) is transferred to reach the junction, the rotary rod ( 4) While about one rotation, the high temperature bonding table 5 bonds the wrapping paper by a predetermined size, and a sharp cutting knife 6 formed between the bonding tables 5 cuts the bonding surface. By packing the product, the chain of the conveying belt (1) by the curved projection (11) formed in the lower portion of the rotating rod (4) before the rotating rod (4) is rotated to join the wrapping paper (5) ( 3) wheels 15 provided on one side of the transfer table 12 protruding from both ends Since the conveyance table 12 is protruded forward on the guide 14 as much as the protruding surface of the protruding protrusion 11, the left and right insertion rods 13 are formed on the other side of the conveyance table 12 and are provided in plurality. ) Is naturally inserted into the side of the wrapping paper to form a curl, which can be held closely, the above-mentioned joining and cutting operations are carried out, and then the transfer table (12) by the continuous operation of the conveying belt (1) When the wheel 15 of the) is released from the protrusion 11 is to be in place by the restoring force of the inner spring (16).

At this time, the joining table 5 is positioned between the insertion rods 13 on both sides, and the spacing between the conveying table 12 in the chain 3 is the joining table 5 at the time of one rotation of the rotary bar 4. If it is set to the interval that would be downward, when the bonding table 5 is bonded to the wrapper, the wrapper can always be formed, the insertion rods 13 formed on both ends of the other side of the transfer table 12 is a spring ( 16 ') is stretched to overcome the elasticity of the wrapping paper itself and the insertion rod 13 is not inserted, and after the predetermined cutting operation to retreat to overcome the elastic force of the spring (16') to make the joints of the finish Will be.

As such, the present invention may be used by combining a transport stand with a chain provided on a transport belt of an existing packaging device. The structure and installation are simple and compatible with various types of machines. It is an invention having the utility that becomes beautiful.
