Definitions
- the invention relates to a frame for an automatic printer, composed of an intermediate part, which is connected on both sides with end parts, wherein a platen is rotatably mounted at both its ends.
- the automatic printer may e.g. be of the daisy wheel type and may be applied in a work processing apparatus.
- end parts are plate-shaped and are connected to the intermediate part by means of a large number of screws, which uses much labour and is therefore expensive. Further the end plates are provided with bearings of artificial material for the platen, which of course forms a further complication.
- the frame according to the invention is characterized in that the end parts are die-castings from artificial material, wherein the platen is directly journalled, whilst the intermediate part consists of an extruded section, which comprises a base plate with at least two upstanding flanges, the end parts being connected to two of the upstanding flanges.
- the end parts are made of artificial material, it is possible according to the invention to journal the platen directly therein. Further, the end parts on both sides may be connected by means of only two screws to two upstanding flanges of the extruded section, which of course leads to a great saving of labour.
- the extruded section is extremely rigid due to the fact that it consists of a base plate and a plurality of upstanding flanges, which is a further advantage of the frame according to the invention.
- each end part may be composed with advantage of two separate halves which are wholly equal, which halves are identical for both end parts.
- this frame is provided with a motor for driving a belt for the displacement of a carriage, this motor being mounted on one of the end plates by means of a motor support, whilst the belt may be tightened by means of a belt tightener.
- This construction again considerably increases the time necessary for the mounting.
- the motor is mounted on one of the upstanding flanges of the extruded section by means of a clamping plate positioned at the side of the relative upstanding flange remote from the motor, the motor being connected to the clamping plate by means of screws, which are passed with play through passages formed in the relative upstanding flange.
- the belt extends between two of the upstanding flanges of the extruded section, whilst the freely rotating roller is connected with one of these two upstanding flanges and is positioned underneath the relative end part.
- a notch may be formed in the upstanding end edges of said upstanding flanges at the relative side and the freely rotating roller may be supported in the two notches.
- the drawing shows a frame 1, which is intended for an automatic printer, which may be e.g. of the daisy wheel type and which may be applied in a work processing apparatus.
- This frame 2 is composed of an intermediate part 2, which consists of an extruded section, and of end parts 3 connected to both sides of the intermediate part 2, which end parts are in the form of die-castings of artificial material, whilst a platen 4 is directly journalled in these end parts.
- the extruded section which forms the intermediate part 2, consists of a base plate 5 with at least two upstanding flanges 6. In the embodiment shown in the drawing by way of example three upstanding flanges 6 are applied.
- Each end part 3 is composed of two separate halves 3', which are wholly equal and which are identical for both end parts, as particularly shown in fig. 2.
- Each half 3' of an end part 3 is connected to one of the upstanding flanges 6 by means of one screw 3" only.
- the application of four equal halves 3' leads thereto that a plurality of holes are formed in the end parts 3, which are not used, but due to this construction the costs of the dies for the manufacture of the end parts 3 are extremely low.
- the passages 12 in the upstanding flange 6 in question are dimensioned in such manner, that the screws 11' pass the upstanding flange 6 with play. In this manner it is possible to use the motor 7 and the clamping plate 10 for tightening the belt 8, so that no separate belt tightener has to be applied.
- the clamping plate 10 comprises a bent over flange 10', wherein an adjustable stop screw 10" is mounted, which contacts the upstanding end edge of the upstanding flange 6 in question.
- the belt 8 is passed over a roller 13 driven by the motor 7 and over a freely rotating roller 14 and extends between two of the upstanding flanges 6 of the extruded section.
- the freely rotating roller 14 is supported by the end in question of the two upstanding flanges 6 extending on either side of the belt 8, which flanges are provided in their upstanding end edges with a notch 15 for this purpose.
- the freely rotating roller 14 is positioned underneath the end part 3 positioned at the side in question.
- a frame 1 for an automatic printer is provided, which may be assembled very quickly, whilst the mounting of the cooperating parts may also take place in a quick manner, so that an important saving in labour costs is obtained.
