Description

Universal Tape Machine (UTM) Head Assembly for Carton Sealing Machines

field of invention

The present invention relates to the field of carton sealing machines. In particular, the present invention relates to tape head assemblies for use in carton sealing machines.

Background of the invention

In the packaging industry, corrugated and cardboard boxes have been used for many years. Various carton sealers have been developed to seal such cartons by applying strips of self-adhesive tape along the edges of the foldable flaps to hold the flaps in the closed position. In particular, such carton sealing machines are widely used in industries such as, but not limited to, household appliances, textiles, food, daily commodities, pharmaceuticals and chemicals, and the like. Many of these carton sealers are designed to accept cartons of any width and height by providing various types of means to control the lateral movement of the side arm assemblies associated therewith and the vertical movement of the top sealing device.

Typically, carton sealing machines are equipped with a tape head assembly and a tape applicator assembly unit which often exhibits two tape applicator rollers which are pivotally mounted for swing. The tape head assembly is provided with a tape reel seat for fixing the tape. The tape in the tape reel may be conveyed to a tape application assembly unit for sealing the foldable wings of the carton by applying strips of self-adhesive tape along the edges of the wings. The tape head assembly is designed in such a way that the tape reel holder facilitates easy removal of the adhesive tape to gain access to the carton interior. The carton sealing machine also includes means for controlling the tracking of the adhesive tape in the tape head assembly.

In addition, these carton sealers can generally utilize four sizes of tapes based on tape width, namely, 1.5 inches, 2 inches, 2.5 inches, 3 inches. In conventional carton sealing machines, different take-up seats defined by the width of the tape are used for each size of adhesive tape. When a specific size of adhesive tape is required, these reel seats can be manually changed to accommodate different changes in tape width. For example, if the desired tape width is 2 inches, a reel for 2 inches of adhesive tape may be secured to the tape head assembly. Similarly, for all tape widths, we need to attach the appropriate reel holder to the tape head assembly by removing the previous reel holder.

However, if so, there is the problem that manually removing and securing the reel holders can be tedious and time consuming, and what type of reel holders will be required and what needs to be kept Inventory, which is also unpredictable, there are instances where a particular size of reel holder is required but the reel holder of that type is depleted in stock, which can cause delays in shipments. Furthermore, when manually securing the tape reel seat to the tape head assembly, the operation is not very reliable due to misalignment of the adhesive tape, thereby lacking in practicality. Also, some customers may require different add-ons for tape reel holders for different products, which results in the need to partially change some parts of the tape head assembly and longer changeover times. Regarding the conventional tape head assembly, it is very difficult to assemble the tape reel holder every time. Accordingly, it would be desirable to provide a universal tape machine (UTM) head assembly for a carton sealing machine that can provide a variety of different sizes of tape without removing the tape reel assembly.

purpose of invention

It is an object of the present invention to provide a universal tape dispenser head assembly for a carton sealing machine which is capable of supplying tapes of various sizes without removing the tape reel assembly.

Another object of the present invention is to provide a universal tape dispenser head assembly of the self-locking type for a carton sealing machine.

Another object of the present invention is to provide a universal tape dispenser head assembly which can be adapted to existing carton sealing machine spindles.

Another object of the present invention is to provide a universal tape dispenser head assembly which reduces the number of variants so that less inventory maintenance costs can be spent.

Contents of the invention

According to one aspect of the present invention, which achieves the above objects, the invention relates to a universal tape dispenser head assembly of the self-locking type for a carton sealing machine, comprising a mounting bracket on which the entire tape head assembly is mounted. Mounting bracket, and center shaft for supporting tape reel seat with tape. Using the force exerted by the elastic means, the locking pin can locate the axial position of the central shaft. The locator cam can be designed with multiple depths to lock the axial position of the central shaft by using a locking pin, and the sheath has a cavity (101) that can be configured to accommodate the central shaft, locking pin , spring and positioner cam. A handle bar may allow the user to pull the central shaft to guide the detent on the depth of the locator cam. Thus, it is possible to provide tapes of various sizes without removing the tape reel assembly.

In addition, a rubber grommet can be used to seal the gap between the center shaft and the sheath to prevent ingress. Tape size locating means, ie, scales, may be provided on the sheath to visually guide the user in manipulating and locating the relevant tape size. A set of ring nuts can be used to secure the center shaft and locator cam to the mounting bracket. The sheath can be fastened to the mounting bracket by several fasteners, notably mounting screws. The boot can be designed to protect the head assembly from dirt, dust and moisture.

Additionally, the mounting bracket can be designed to be retrofitted on existing carton sealers where the central shaft is also suitable for retrofitting. The elastic means, preferably a spring, are positioned on the central axis. The spring can be designed to allow easy one-handed operation and maintain the accuracy of the position of the reel seat. The locator cam locks the position of the center shaft without axial play and allows for easy positioning by providing sufficient access for the locking pin. The handle bar provides easy two-finger operation.
