Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a time card stage feeding device suitable for use in a weekly wage type time recorder.

[Conventional technology]

Weekly wage type time recorder means one week or
This is a time recorder used to pay wages in two-week units, and the time card is advanced once a day by a raising rack raised by a step-feeding gear to change the printing column, and the time card is changed seven times a day. , or, after the 14th stage feed, the gear disengages from the stage feed gear and the rising rack lowers, aligning the top column of the time card with the printing position, and printing one stage at a time towards the bottom column again. It's structured.

Therefore, the conventional weekly wage type time recorder has 1
Weekly and two-week versions were manufactured separately, and these were used depending on the pay system.

[Problem that the invention seeks to solve]

However, in recent years, many companies and shops have changed their pay structures midway through the use of part-time workers, the introduction of flextime systems, etc. Due to this reverse switching, there were many cases where the time recorder that had been used until now became unusable.

Therefore, an attempt was made to develop a common type weekly wage type time recorder that can be used for both one-week and two-week periods. However, as mentioned above, 1
For weekly use, it is necessary to lower the rising rack to the lowest level after 7 steps, and for 2 weeks, it is necessary to lower the rising rack after 14 steps.
There was no device that could accurately switch between 7 and 14 stages. It is also possible to consider a type of time recorder in which two sets of raising racks and stage feed mechanisms, one for 7 stages and one for 14 stages, are separately built into a single time recorder, and these are used by switching between them as appropriate. However, it was not realized because the switching work was troublesome and the entire device became complicated and costly.

Furthermore, the start day of the week when printing starts, that is, the day of the week printed in the top column of the time card, is always fixed to a specific day of the week by the day type wheel, so it can be changed based on customer requests or changes in the pay system. There was also a problem in which the start day could not be changed on the spot.

Therefore, the technical problem of the present invention is to
It can be used by freely switching to either weekly mode, and the switching operation is extremely easy.The structure is simple and can be manufactured at relatively low cost.The start day of the week when printing starts can be easily changed. The purpose of the present invention is to provide a stage feeding device for weekly salary time cards.

[Means for solving problems]

The measures taken in the present invention to solve the above technical problems are as follows.

(1) A main gear body that rotates integrally with the day of the week feed gear is attached to the circumferential surface of the boss connected to the day of the week feed gear so that its rotation can be adjusted freely.

(2) On the circumferential surface of the main gear body, there is an intermittent gear in which multiple sets of feed dog groups are formed equally for 7 days and toothless parts are formed alternately, and the positions of the above toothless parts are alternately corresponded to. To provide stopper teeth having two widths, wide and narrow.

(3) A secondary gear body that is movably mounted on the mounting shaft and is provided with a rising gear that constantly meshes with the rising rack is provided with two sets of interlocking gear groups that can freely mesh with the intermittent gear of the main gear body, Between these interlocking gear groups, there are provided first and second switching parts that are out of mesh every seven days, corresponding to the toothless part of the intermittent gear.

(4) The inner side of the other side circumferential surface of the slave gear body can be constantly engaged with the two types of wide and narrow stopper teeth of the main gear body, and when the slave gear body is moved in the axial direction, the A first locking protrusion located outside the engagement range of the narrow stopper tooth is provided in correspondence with the first conversion portion.

(5) A second locking protrusion, which is always engaged with either of the two types of wide and narrow stopper teeth, is installed on the outer side of the other peripheral surface of the slave gear body, regardless of the movement of the slave gear body. Provided corresponding to the second conversion section.

[Effect]

The means constituted by each of the elements (1) to (5) above operates as follows.

The factor (1) above is that the main gear body is rotatably attached to the day-of-the-week feed gear, so the main gear body can be rotated to match the engagement start position of each gear described below to any day of the week. This allows you to set the start day to any day of the week.

According to the above element (2), as the day of the week feed gear advances the day of the week, the main gear body, which has an intermittent gear and two types of wide and narrow stopper teeth on its circumferential surface, rotates integrally.

According to the above element (3), when the slave gear body rotates in conjunction with the main gear body, the ascending gear advances the ascending rack in steps and changes the printing column of the time card. Furthermore, when the switching part of the slave gear body matches the toothless part of the intermittent gear, the mesh is disengaged and the raising rack descends, allowing the top column of the time card to be aligned with the printing position.

According to the above elements (4) and (5), when the stage feeding device of the present invention is used as a weekly type (seven stage type), the first locking protrusion is attached to one of the stopper teeth of the intermittent gear. When engaged and step feeding is started, step feeding progresses and when the main gear body is fed by the day of the week at 0:00 on the 8th day, the meshing between the main gear body and the reverse gear body is released, The rising rack descends while rotating the slave gear body under its own weight.

On the other hand, when sending time cards in two-week format, the slave gear body is moved in the axial direction, the second locking protrusion of the slave gear body is engaged with the narrow stopper teeth of the main gear body, and the time card is sent in stages. If this is started, the wide stopper tooth of the main gear body engages with the first locking protrusion of the slave gear body at the time of the 7th stage feed, so the meshing of both gear bodies can be advanced to the 7th stage. can be done, therefore,
After that, it will be possible to advance this engagement to 14 stages and send it for two weeks.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.

The day of the week feed pawl 9 meshes with the day of the week feed gear 5 as shown in FIG. The ratchet-type day-of-the-week feed gear 5 is moved by one tooth to move the day-of-the-week type wheel 4 to the day of the week. Therefore, above 3
Each of the printing wheels 2, 3, and 4 is fed sequentially in conjunction with each other, so that printing characters corresponding to the current day of the week, hour, and minute can be set at the printing position.

Next, what is generally indicated by the reference numeral 10 is a ring that is fitted onto the circumferential surface of the fixing boss 5a of the day-of-the-week feed gear 5 so as to be in contact with one side of the day-of-the-week type wheel 4, and also concentrically. The main gear body 10 has a substantially ring shape, and an intermittent gear 11 is formed on one side circumferential surface of the main gear body 10, as shown in FIGS. 1 to 3. The entire intermittent gear 11 is as shown in FIGS. 2 and 3.
The first, second, third, and fourth feed dog groups 11a, 11b, 11c, and 11d are divided into 56 equal parts, each of which is formed into a set of 10 teeth for 7 days, and Each of the first, second, third, and fourth toothless portions 11e, 11f, 11g configured by missing four teeth,
11h are provided alternately in the circumferential direction. Further, in FIGS. 1, 4 to 6, 12a', 12b', 12c', and 12d' are the side surfaces of the main gear body 10, respectively, and may be the toothless parts 11e to 11h. Brackets protrude at corresponding positions, and each of these brackets has a bracket located approximately at the center of each of the toothless portions 11e to 11h (actually approximately at the feed tooth group side opposite to the rotational direction of the main gear body 10). 1
A total of four stopper teeth 12a, 12b, 12c, and 12d are provided to protrude outward in correspondence with the positions of the stopper teeth, etc.), and among these stopper teeth, the first and third teeth The stopper teeth 12a, 12c corresponding to the toothless portions 11e, 11g are wide stopper teeth as shown in FIGS. 1 and 5, while the second and fourth toothless portions 11f, 1
The stopper teeth 12b and 12d corresponding to 1h are

Reference character a denotes a locking pawl connected to, for example, the fourth bracket 12d', and this locking pawl 10a is configured to elastically engage with one of the engaging grooves 5b. The engagement state between the locking pawl 10a and the engagement groove 5b is as follows when the day of the week type wheel 4 is rotated to feed the day of the week in the directions of the arrows in FIGS. 2 and 3 by the ratchet gear 5 for feeding the day of the week. , engaged with the main gear body 1
However, if only the main gear body 10 is forcibly rotated by hand in the clockwise rotation direction in the drawing, that is, in the rotation direction of the day of the week type wheel 4, the engagement will be disengaged and the main gear body 10 will be rotated against the boss portion 5a. The locking pawl 10a can be freely rotated to engage the other engaging groove 5b, and thus,
By appropriately shifting the relative positional relationship between each of the toothless parts 11e to 11h of the main gear body 10 and the day of the week of the day type wheel 4, the top column of the time card can be set to any day of the week corresponding to the engagement groove 5b. Can be changed.

Next, in each figure, the reference numeral 13 indicates a slave gear body rotatably and movably attached to the mounting shaft 7, and one side circumferential surface of the slave gear body 13 has a total area of 15 Divided into equal parts, and one of them is missing 14a
A total of 14 ascending gears 14 are formed, and each ascending gear 14 is equipped with an ascending rack equipped with a card receiving lever (not shown) for determining the printing stage as shown in FIG. 15 mesh with each other, and the slave gear body 13
The mechanism is such that when it rotates, the raising rack 15 can be advanced one stage at a time. The above-mentioned missing portion 14a is provided as a mark to make it easier to identify each tooth of the ascending rack 15 and the opposing tooth of the ascending gear 14. If a mark or the like is provided, there is no need to deliberately remove the tooth as shown in the drawing.
Moreover, the entire central circumferential surface portion of this slave gear body 13 is
It is divided into 30 equal parts, including a total of 10 first interlocking gear groups 16a and a total of 11 second interlocking gear groups 16b that mesh with the intermittent gears 11 of the main gear body 10.
However, the first conversion part 17a has four teeth missing between them.
It is formed in the circumferential direction with a second conversion portion 17b having five missing teeth interposed therebetween. Furthermore, the other side circumferential surface portion of the driven gear body 13 corresponds to a substantially central portion of the first conversion portion 17a (specifically, a portion that is approximately half a pitch closer to the first interlocking gear group 16a from the center). , and if it is protruded to a position closer to the inside of the slave gear body 13 as shown in FIG. 7, and the slave gear body 13 is set at the weekly position shown in FIG.
As shown in FIG. 8, the main gear body 10 can be freely engaged with any of the stopper teeth 12a to 12d, but the slave gear body 13 is placed at the two-week (14-day) position along the mounting shaft 7. As it moves, as shown in FIG. 9, the first locking protrusion 18a located outside the rotation range of the narrow stopper teeth 12b and 12d and the second interlocking gear group 16b of the second conversion portion 17b are engaged. It corresponds to the closer part (specifically, the part one pitch away from the first tooth of the second interlocking gear group 16b) and is protruded toward the outside of the gear body 13 as shown in FIG. Therefore, regardless of whether the follower gear body 13 is set at the weekly position or the two-week position, the second engaging member always engages with all of the wide and narrow stopper teeth 12a to 12d, as shown in FIGS. 8 and 9. A stopper 18b is provided in a protruding manner.

Incidentally, the ascending gear 14 of the subordinate gear body 13 and each interlocking gear group 16a, 16b are arranged so that the engagement with the ascending rack 15 and the intermittent gear 11 will not be disengaged even if the subordinate gear body 13 is moved. The tooth width is wide. Further, in the figure, reference numeral 19 is an operating lever that moves the driven gear body 13, and the driven gear body 13 is connected to this operating lever 1.
9 can be set by appropriately switching between the weekly pay position shown in FIG. 1 and the two-week position shown in FIG. 9. In FIG. This is a positioning groove for the week. Furthermore, the first
In the figure, 20 is a ratchet gear for minute feed attached to one side of the minute type wheel 2, and 21 is a cam for time feed.

The present invention has the configuration as described above, and next,
The operation will be explained according to the drawings.

When the day of the week feed pawl 9, which is operated once a day, advances the day of the week feed gear 5 by one tooth, the day of the week type wheel 4 and the main gear body 10 are fed by one pitch of the day of the week. Then,
Since the slave gear body 13, which has the interlocking gear 16a or 16b meshed with the intermittent gear 11 of the main gear body 10, is also rotated by one pitch, the raising gear 14 raises the raising rack 15 by one step in the direction of the arrow in FIG. , you can advance the time card print column one step.

The above card sending is based on weekly wages (7 dan) and 2 weeks (14 dan).
In the case of weekly delivery, first set the slave gear body 13 in the position shown in FIGS. 1 and 8, and then
As shown in Figure 0, the first locking protrusion 18a provided inside the gear body 13 is engaged with one of the stopper teeth (in the drawing, the wide first stopper tooth 12a) to start the above-mentioned stage feeding. . Weekly wage step feed is driven by gear body 1
This is done by the meshing of the first interlocking gear 16a of No. 3 and one of the feed dog groups of the intermittent gear 11 (the first feed dog group 11a in FIGS. 2 and 3).
When the side is moved one pitch in the direction of the arrow (clockwise direction) in FIGS. 2 and 3, the slave gear body 13 is moved one pitch in the direction of the arrow (counterclockwise direction) in the drawings, and rises. Raise the rack 15 one step.

0:00 on the 8th day after the 6th step above
When the main gear body 10 is advanced by the day of the week, the first interlocking gear 16a of the slave gear body 13 and the first feed dog group 11a on the main gear 10 side are disengaged, as shown in FIG. 13 is reversed in the direction of the arrow in FIG. 11 due to the weight of the engaged lifting rack 15, and quickly returns the lifting rack 15 downward. This reversal is carried out until the first locking protrusion 18a engages with the next stopper tooth (narrow second stopper tooth 12b in the drawing), and due to the engagement, the slave gear body 13 is rotated as shown in FIG. You can return it to the starting position and align the top column of the time card with the printing position.

Next, when sending time cards in two-week format, first move the slave gear body 13 to the position shown in FIG. 9, and then move the second locking protrusion 18b of the slave gear body as shown in FIG. It engages with the narrow stopper tooth (second stopper tooth 12b in the drawing) on the main gear body 10 side to start stage feeding. During the first week of two-week feeding, the second interlocking gear group 16b is formed with one more tooth than the first interlocking gear group 16a, and in the case of FIG. 12, the second interlocking gear group 1 is formed.
1b, the rising rack 15 is moved in steps, and at the seventh step, as shown in FIG.
is successfully engaged by the meshing action of the second interlocking gear 16b, which has one more tooth, and can proceed to the seventh stage. Next, when the first interlocking gear group 16a and the third feed dog group 11c in the case of FIG. 13 engage with each other, both the master and slave gear bodies 10 and 13 rotate in conjunction with each other, and when they move up to the 14th stage, the gears shown in FIG. As before, the next 15th stage becomes free and the slave gear body 13 starts reverse rotation. At this time, the stopper tooth on the main gear body 10 side near the slave gear body 13 is the narrow fourth stopper tooth 12d.
and this fourth stopper tooth 1 during reverse rotation.
The slave gear body 13 rotated within the engagement range of 2d
The first locking protrusion 18a is also provided inside the side locking protrusion.
Therefore, the gear body 13 continues to reverse rotation without engaging the two, and the reverse rotation is stopped again at the starting position shown in FIG. 12, allowing the lifting rack 15 to be lowered to the lowest stage.

Further, in the present invention, the main gear body 10, which rotates integrally with the day-of-the-week type wheel 4, is rotated in one direction so that the locking pawl 10 is disengaged from the engagement groove 5b, and the locking pawl 10 is moved into the other engagement groove 5b. If engaged, the relative positional relationship between each of the toothless parts 11e to 11h of the main gear body 10 and the day of the week type wheel 4 can be shifted, and the top column of the time card can be set or changed to any day of the week. .

〔effect〕

As described above, the present invention can perform step-feeding of the ascending rack by the main gear body that feeds the days of the week integrally with the day-of-the-week type wheel, and the secondary gear body that meshes with the main gear body. The structure is much simpler and smaller than that of the previous model, and the number of parts is reduced.
Significant cost reductions can be achieved.

Further, according to the present invention, by simply changing the movement of the slave gear body, the stage feed can be freely switched between the weekly type and the biweekly type. It also has the advantage of being able to set and change the top column of the timecard on any day of the week by shifting its relative position with the It is suitable for use on a recorder.
