## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present disclosure relates to a book sewing machine, particularly a semi-automatic book sewing machine.
2. Description of the Prior Art
A book sewing machine is a conventional device to wind a spiral coil at the lateral side of a stack of paper.
Conventional book sewing machines are divided into two types: the full-automatic book sewing machine based on full-automatic control for convenient operation features bulky volume and numerous costly components which occupy more space and impose financial burden on a small enterprise or company not specializing in book publishing; the full-manual book sewing machine features advantages such as small volume, fewer components, less space requirement, inexpensiveness and full-manual operation but disadvantages like strenuous effort and time consuming operation which are inconvenient to a small enterprise or company occasionally binding stacks of paper.
Furthermore, resources may be wasted in more than one book sewing machine purchased by a company owner, which requires spiral coils different in diameter to be wound on stacks of paper, because either a full-automatic book sewing machine or a full-manual book sewing machine is applicable to one type of spiral coil with a single dimension.
SUMMARY OF THE INVENTION
For development of an alternative book sewing machine which is distinct from a conventional one, characteristic of less space requirement, fewer components and convenient use, and applicable to spiral coils different in diameter, a semi-automatic book sewing machine in the present disclosure comprises: a base with a book storage region, a spiral coil storage region and a coiling rack thereon and a base fixture block at one side; an actuation device with a mobile platform, a motor, a rotary drum, a bottom panel, a manual adjustment kit, two slip joint plates, a linkage, at least a push-pull member, a binder plate and a touch switch. The mobile platform which is opposite to and glidingly contacts the base has a first elliptical hole; the motor is installed on the mobile platform for output of a rotary force; the rotary drum mounted on the mobile platform and connected to the motor is driven to spin locally by the motor; the bottom panel installed on the bottom of the mobile platform develops a second elliptical hole and comprises a panel fixture block at one side; the manual adjustment kit comprising a shaft, a first cam eccentrically connected to the shaft and held in the first elliptical hole, a second cam eccentrically connected to the shaft and held in the second elliptical hole, and a rotary knob connected to and coacting with the shaft is used in driving the mobile platform and the bottom panel for displacement; the two slip joint plates glidingly contact both the base and the mobile platform; the linkage is connected between the two slip joint plates; the two push-pull members are connected to the linkage for outward and inward movements back and forth; the binder plate pivotally fitted at the linkage communicates with the push-pull members for pivotal compression and separation under effect of the push-pull members; the touch switch installed on the mobile platform is used to control and deactivate the motor when the touch switch is contacted. As such, a semi-automatic book sewing machine which occupies less space and consists of fewer components can be easily operated and applicable to spiral coils of different diameters.

The above descriptions present components installed on a semi-automatic book sewing machine in a preferred embodiment. The characteristics of a semi-automatic book sewing machine in service are specified as follows:
A stack of paper 41 to be bound with a spiral coil should be placed on thickness measurement region 11 of base 1 for checking a thickness of stack of paper 41 and transferred to book storage region 13 (FIG. 6). A spiral coil 42 with a diameter matching the thickness of the stack of paper 41 is inserted between base fixture block 16 and panel fixture block 242 (FIG. 7). A user rotates rotary knob 39, driving first cam 62 as well as second cam 63 to spin by shaft 61 simultaneously and mobile platform 2 as well as bottom panel 24 to be shifted synchronously for translational movement of mobile platform 2 along transverse grooves 18 (FIGS. 8 and 9). Linkage 52, push-pull members 51, and binder plate 31 slide with slip joint plates 53 along arc-shaped grooves 22 (FIGS. 8 and 9) and make no translational movement related to active mobile platform 2; slip joint plates 53 vertically moving along lifting grooves 19 and longitudinal grooves 17 properly drive linkage 52, push-pull members 51 and binder plate 31 upward or downward (FIGS. 8 and 9). A user can stop rotating rotary knob 39 with both panel fixture block 242 and base fixture block 16 just contacting spiral coil 42.
A user should place spiral coil 42 into spiral coil storage region 14 of base 1 (FIG. 10) and press an electric control switch (now shown in FIG. 10) so that push-pull members 51 drawn inward drive binder plate 31 to pivotally spin downward (FIGS. 10 and 11) and gently press spiral coil 42 on rotary drum 25 (FIG. 12). Motor 3 starts driving rotary drum 25 to revolve and lead spiral coil 42 to forward move rotationally along coiling rack 15 and penetrate thorough holes 45 on the stack of paper 41 (FIG. 13). Spiral coil 42 arriving at a default position resists touch switch 32 (FIG. 14) and deactivates motor 3 through active touch switch 32; push-pull members 51 retreating outward drive binder plate 31 to pivotally spin upward (FIG. 15). Finally, the stack of paper 41 bounded with spiral coil 42 can be taken from a book sewing machine (FIG. 16).
In present disclosure, a semi-automatic book sewing machine which features fewer components and reduced volume in contrast to a conventional full-automatic book sewing machine and needs less time and manpower in coiling compared with a conventional full-manual book sewing machine is a competitive tool with advantages of full-automatic and full-manual book sewing machines.
Moreover, a semi-automatic book sewing machine in present disclosure is used in binding stacks of paper of distinct thicknesses with spiral coils different in diameter and contributes to not only convenient use but also cost down because of no requirement for purchasing or book sewing machines used in stacks of paper of distinct thicknesses or spiral coils different in diameter.
Additionally, actuation device A in the above embodiment comprises two electromagnetic devices 5 (FIG. 3), each of which links one of push-pull members 51 and supplies power to push-pull members 51 for outward or inward movement.
In the above embodiment, actuation device A comprises at least a convey belt 46 (FIG. 2) which is connected between an output shaft 47 of motor 3 and a spindle 49 of rotary drum 25 and used in conveying a rotary force of motor 3 to rotary drum 25 for rotation.
In the above embodiment, actuation device A comprises a baffle 48 and a sensor 44 (FIGS. 3 and 12). Baffle 48 is installed on mobile platform 2 and driven with touch switch 32; sensor 44 is mounted on mobile platform 2; baffle 48 is shifted with touch switch 32, which is contacted by spiral coil 42 and shifted upward, and blocks sensor 44 for deactivating motor 3 by a signal from sensor 44.
above descriptions are examples of preferred embodiments which do not restrict scope of a semi-automatic book sewing machine; any equivalent change or improvement without departing from spirit of semi-automatic book sewing machine should be incorporated in claims herein. Many changes and modifications in the above described embodiment of invention can, of course, be carried out without departing from the scope thereof.
