Abstract

PURPOSE:To precisely set the degree of parallelization between a winding core and a core different from the winding core and the positional relation based on the width of an ink ribbon by providing, close to a ribbon running route between a cutting tool and the winding core, a core holding equipment for holding the different core in parallel to the winding core and at a fixed position in the lateral direction of the ink ribbon. CONSTITUTION:A wide ink ribbon (r) drawn out from an original roll is cut into a determined width by means of a cutting tool 3 and then wound on a winding core 4 in a rolled form so as to have the smoothed end surfaces. After completion of the winding, the top end part of the ink ribbon (r) wound on the winding core 4 is connected to a second core 5 held by a core holding equipment C situated close to a ribbon running route between the cutting tool 3 and the winding core 4. In this case, as the winding core 4 is in the parallel state to the different core 5, the ink ribbon connected to the different core 5 is never twisted and bent.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an ink ribbon manufacturing device used in typewriters, computer printers, etc.
The present invention relates to an apparatus for manufacturing an ink ribbon roll, in which a long ink ribbon material formed by applying transfer ink or the like to a base material is cut into a predetermined width using a cutting tool, and then wound around a winding core.

[Conventional technology]

When using this type of ink ribbon roll,
Requires a separate core for winding the used ink ribbon. Therefore, the leading end of a certain length of ink ribbon wound around the winding core (if a leader tape is connected to the end of the ink ribbon, this becomes the leading end of this leader tape) is A process for connecting to the core is required.

Conventionally, when the winding operation of the ink ribbon onto the winding core is completed, this winding core is removed from the manufacturing device, and the tip of the ink ribbon wound into a roll around the winding core is separated from the winding core. It was glued to the core by hand.

[Problem to be solved by the invention]

However, when manually adhering the tip of the rolled ink ribbon of the take-up core to another core, the axes of both cores must be parallel and the ink ribbon will not be twisted. If the ink ribbon is not connected properly, there is a risk that the ink ribbon may wrinkle or bend during use, which may impede the image forming function.

Therefore, when adhering the tip of the ink ribbon wound around the take-up core to another core, it is necessary to pay close attention to the connection, resulting in deterioration of work efficiency.

In particular, as the width of the ink ribbon increases, it becomes more difficult to maintain the parallelism of the axes of both cores, and at the same time, the ink ribbon becomes more likely to be twisted, which further exacerbates the aforementioned deterioration of work efficiency. was there.

In view of the above-mentioned circumstances, the present invention provides a useful ink ribbon roll manufacturing apparatus that can reliably and easily connect the tip end of the ink ribbon wound around the winding core to another core. have a purpose.

[Means to solve the problem]

The present invention is an apparatus for manufacturing an ink ribbon roll that winds a long ink ribbon roll onto a winding core while cutting it into a predetermined width using a cutting tool, the manufacturing device comprising: The greatest advantage is that a core holder is provided close to the ribbon running path to hold a core other than the take-up core parallel to the take-up core and at a constant position in the width direction of the ink ribbon. Features.

Further, in claim 2 of the present invention, the winding core and the core holder are each attached to an eccentric position of a single rotating body having a rotation axis parallel to the axes of both cores. The rotating body is held at a constant position during the winding operation of the winding core, and when the winding operation is stopped, the core holder enters the ribbon traveling path. It is characterized by being configured to be rotatable in both directions.

Furthermore, in claim 3 of the present invention, a leader tape is connected to one or both of the ends of the ink ribbon of a certain length during the ribbon traveling path between the ink ribbon original and the core holder. It is characterized by having a structure that allows

[For production]

The wide ink ribbon unwound from the original ink ribbon is cut into a predetermined width by the cutting tool, and then wound into a roll around the winding core with its end surfaces flush. When this winding process is completed, the tip of the ink ribbon wound around the winding core is held by a core holder located close to the ribbon running path between the cutting tool and the winding core. Connect to another core.

At this time, since the winding core and another core are in parallel,
The ink ribbon connected to this other core will not be twisted or bent.

Further, when the above-mentioned configuration of claim 2 is adopted, when the rotating body is rotated at the time when the winding operation of the ink ribbon onto the winding core is completed, the rotating body is rotated. The core holder enters the ribbon travel path, and another core held by the core holder automatically comes into contact with the tip of the ink ribbon.

Therefore, by forming an adhesive layer at a predetermined position on the tip of the ink ribbon, the tip of the ink ribbon can be automatically connected to another core.

Furthermore, when the configuration of claim 3 described above is adopted, a leader tape is attached to the end of the ink ribbon to be wound up on the take-up core during the ribbon traveling path from the ink ribbon original to the take-up core. Can be connected.

(Effects of the Invention) Therefore, the present invention achieves the original function of this type of ink ribbon roll manufacturing apparatus, that is, the ink ribbon supplied from the ink ribbon original roll is delivered to the winding core in a state in which the end surface is flush with the ink ribbon. By effectively utilizing the excellent function in terms of winding position accuracy, simply holding another core in the vicinity of the ribbon traveling path along which the end of the ink ribbon moves as described above;
The parallelism between both cores and the positional relationship based on the width of the ink ribbon can be accurately set.

Therefore, following the winding operation of the ink ribbon onto the winding core, the leading end portion of the ink ribbon wound into a roll on the winding core (a leader tape is connected to the end of the ink ribbon). In some cases, the tip of the leader tape) can be accurately and easily connected to another core, making it possible to greatly improve work efficiency compared to the conventional method.

Further, as described above, when the configuration according to claim 2 is adopted, there is an effect that the work of connecting the tip end portion of the ink ribbon to another core can be performed more efficiently.

Furthermore, as described above, when the configuration according to claim 3 is adopted, the step of winding the ink ribbon on the winding core, the step of connecting the leader tape to the end of the ink ribbon, and another step. The process of connecting the tip of the ink ribbon to the core can be carried out efficiently in a series of assembly operations.
