Abstract
Device (2) for the transport of continuous forms (1) for printing units, of the type where continuous forms (1) are moved forward by means of a traditional feeder and leave the printing unit by the sound deadening cover (3), characterized thereby that an additional feeder (2) for the continuous forms is provided.
Description
- The present invention relates to a device for the transport of continuous forms for printer units, more commonly known by the name of printers.
- In a special embodiment the invention relates to an additional feeder which, besides the traditional feeder used for printers to transport continuous forms, is installed on a sound deadening cover known as such, which has been put over the printing unit.
- It is known that it often occurs when using printers or printing units, printing their data on continuous forms, that these forms are drawn to one side, possibly causing an accumulation of paper. Such a problem is presenting itself particularly on printing units having a sound deadening cover, where the continuous forms have to be pushed into this sound deadening cover.
- Aforesaid problem of paper accumulation often arises also due to the fact that printing units often are unsuitable to function with continuous forms made of different kinds of paper.
- If the kind of paper used is too thin of too thick, the transport of the continuous forms may cause trouble due to a difficult passage of the unsuitable paper through the sound deadening cover.
- The present invention is therefore relating to a device for the transport of continuous forms in printing units or printers, permitting to avoid systematically the aforesaid and other disadvantages.
- The device according to the invention moreover presents the great advantage that a better sound reduction by the sound deadening cover is obtained and that special traction rollers are used leaving no traces of ink when transporting the printed continuous forms.
- For this purpose the present invention consists therefore of a device for the transport of continuous forms for printing units of the type transporting the continuous forms by means of a traditional feeder and leave the printing unit by the sound deadening cover, whereby this device according to the invention contains an additional feeder for the continuous forms. In a preferred embodiment, this additional feeder has been built in in the sound deadening cover and both these elements form one construction unit. Therefore the invention also ralates to such an autono nous unit which can be applied at several types of printers.
- In order to show the characteristics of the invention more clearly, a preferred example is described hereafter without any limiting character, with reference to the attached drawings where:
- Figure 1, represents an additional feeder for continuous form, built in in the sound deadening cover;
- Figure 2, represents roller elements, used for the additional feeler;
- figure 3, represents a switch element for the device;
- Figure 4, represents a possibility to drive the roller elements of figure 2 by means of an electric motor.
- The device for the transport of
continuous forms 1 according to the invention consists of a traditional fesder built in in the printing unit for the transport of thesecontinuous forms 1, which are not shown in the figures, and in combination herewith anadditional feeder 2, which, preferably, is built in in the sound deadening cover 3. This sound deadening cover 3 can or cannot be carried out to form one piece with of the covering of a printer or printing unit. - The
additional feeder 2, consists mainly of at least tworoller elements continuous forms 1 can be picked up and transported and a driving mechanism to drive at least one of theroller elements - This driving mechanism consists preferably of an electric motor 6, an electric supply 7 and a switch element to connect or to separate the motor 6 to or from the electric supply7.
- The
roller elements shaft rubber rollers rollers - The
shafts roller elements ball bearings walls 14 provided for that par- pose. In accordance with a variant, self-lubricating bronze bearings may be used. - The
upper shaft 8 is attached in such a way that it can adapt its position automatically in accor lamce with the thickness of the paper used for thecontinuous forms 1. - The connection between the electric motor 6 and the driven shaft, is this
case shaft 9, is made by means of a direct transmission formed here by thesilicon thube 15, slipped over themotor shaft 16 and theshaft end 17 ofshaft 9 respectively and attached thereto. - The motor 6 is preferably of the direct current type and is, in accordance with this embodiment operating at a tension of four and a half to twelve volt and the supplied current has an intensity of 2,5 Amp.
- The switch element is formed by a
microswitch 18 which can be switched on by means of a slidingarm 19 by the presence of the continuous forms. For this purpose themicroswitch 18 is therefore preferably placed in the vicinity of the contact plane between the two roler elements, 4 and 5 respectively. - The
complete feeder 2 can or cannot be entirely or partly built in in the the sound deadening cover 3. In the represented embodiment the motor 6 and theroller elements socket 21 is proviced in the sound deadening cover 3 with which an interruptable connection can be made by means of a plug 22, between the electric supply 7 and the electric motor 6. The electric supply 7 however form one compact unit with the additional feeder. - The device is functioning as follows. If aforesaid traditional feeder supplies a form, and this form gets in contact with the sliding
arm 19, of themicroswitch 18 at theadditional feeder 2, the electric motor 6 starts. As long as there will be any paper for theroller elements continuous forms 1. irrespective of the fact whether those forms are moved forward already by the traditional feeder at that moment or not. The electric motor and the electric supply 7 are, of course, of such a conception that they will not be damaged by overheating or burning when in the switched on position, the continuous forms are not moving. - In a preferable embodiment, the whole represented in figure 1, is built as a separate unit and can be commercialized as such.
- In addition, the
necessary sheet guides 23 may also be provided. - The casing of the complete device, or in other words, the sound deadening cover 3, is preferably made of injection moulded plastic, like for instance PVC.
- The present invention is in no way limited to the embodiment as described as an example and represented in the attached drawings, but such a device for the transport of continuous forms can be realized in numerous forms and dimensions without going beyond the scope of the invention.
