BEDILATE'WITII DRIVE MECHANISM FOR INSTALLING PROCESS UNITS OF AUTOMATIC PROCESSING LINE This is a continuation of application Ser. No. 128,862, filed Mar. 29, 1971, now abandoned.

BACKGROUND OF THE INVENTION The present invention relates to automatic processing lines an more specifically, to bedplates with a drive mechanism, intended for installing the process units of automatic processing lines This invention can be used most sucessfully in high-efficiency automatic processing lines with a short cycle required for processing the product, for example, radio components.

PRIOR ART Widely known in the art are bedplates with drive mechanisms comprising an electric drive motor and a driving shaft coupled to said motor, with both mounted on the base of the bedplate, and said driving shaft actuating the process units installed on the mounting pads of the bedplate.

While designing and manufacturing the known automatic processing lines, the bedplates with the drive mechanisms are designed and manufactured to suit the specialized group of process units. For ensuring the installation of the process units and for the most efficient arrangement of the group of process units, the mounting pads of the bedplate are installed at different levels and planes. The drive motor and the driving shaft are also installed so as to ensure the best arrangement of the process unit drive and convenience in its servicing. During installation of the entire automatic processing line on the known bedplates intended for the specialized group of process units, it becomes necessary to make special conveying connections between the process units of the jointed bedplates due to the different levels of product conveyance.

These conveying connections make it difficult to obtain a single operating cycle of the process units of the entire automatic processing line thus complicating corisiderably the system of synchronization, and calling for the use of accumulators which, in turn, leads to difficulties in the manufacture and'operation of the line. In the automatic processing lines whose process units are installed on the known bedplates thelong period of time required for the passage of the product through the conveying connections and accumulators affects adversely the efficiency of the entire line.

OBJECTS AND SUMMARY OF THE INVENTION The present invention is directed to providing a bedplate with a drive mechanism which will be fit for use with any kind of automatic processing line, thereby ensuring the conveyance of the products in one direction and on one and the same level throughout the line.

. With this object in view, the invention is a bedplate with a drive mechanism wherein, according to the inand through which the process units are set in motion by the driving shaft, with said coupling units being adapted for displacement along the axis of the driving shaft and for being turned through 180 with relation to their respective output ends of the shaft connected with the process units.

It is practicable that the coupling unit be made in the form of a single-jaw coupling and an irreversible coupling linked rigidly with each other by a bevel gear drive, with one shaft of the coupling unit with the jaw coupling carrying a gear wheel which meshes with the vention, the supporting surface for the installation of the process units is arranged horizontally along the longitudinal axis of the bedplate throughout its length while under the supporting surface, along the longitudinal axis of the bedplate, throughout its length, is installed a driving shaft with a cross member installed on at least one side of said shaft. The cross member has datum surfaces on which coupling units are installed gear wheel installed on the driving shaft and with provision for moving along said shaft.

It is also practicable that the ends of the driving shaft be provided with couplings which can be extended beyond the outline of the bedplate for connection with the shaft of the other jointed, the driving shaft being coupled to the drive motor by a slipping clutch and an overrunning clutch.

' Such a design of the bedplate with the drive mechansim allows the process units to be installed on the bed plate in any desired sequence and on one and the same level along the bedplate axis. The process units can be connected with the drive in any point of the bedplate by displacing the coupling unit as required. The directions of rotation can also be changed 'by turning the coupling unit through Operation of the process units installed on the bedplate in synchronism with the other process units is ensured by the unit comprising a single-jaw coupling and an irreversible coupling which stop the process units at a precisely required moment and start them again at a predetermined stage of the cycle.

In addition, the ends of the driving shaft are provided with couplings which can be extended beyond the outline of the bedplate. In this case, the driving shaft is coupled to the electric drive motor by a slipping clutch and an overrunning clutch. Such an arrangement combines the drive mechanisms of the different bedplates into a single kinematic chain, thus providing for synchronous operation of all the process units in the automatic processing line. This arrangement dispenses with the need for the conveying connections and accumulators between the jointed bedplates.

By means of the present invention it becomes possible to produce various parts on universal bedplates with drive mechanisms by designing and manufacturing automatic processing lines to any desired layout. The employment of the present bedplates with the drive mechanism cuts down the designing time by 2030 percent and reduces the total time required for manufacturing and starting the automatic line by 30-40 percent.

The present invention will be better understood from the following detailed description thereof given by way of example with reference to the accompanying drawings, in which: i

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a section of the automatic processing line with the bedplate according to the invention;

FIG. 2 is a diagrammatic view showing the coupling of theelectric drive motor with the driving shaft of the bedplate according to the invention;

FIG. 3 is a section taken along line III-III in FIG. 2, the view looking in the direction of the arrows; and

FIG. 4 is a diagrammatic view showing a unit comprising a single-jaw coupling and an irreversible coupling of the bedplate according to the invention.

DETAILED DESCRIPTION OF THE INVENTION The section of the automatic line (FIG. 1) is designed for the production of radio components, particularly resistors. This section incudes process units installed on bedplates l and 2 with the drive mechanisms.

The bedplate 1 comprises end face walls 3 and 4 interconnected by longitudinal lower tie rods 5 and upper tie rods 6. The upper tie rods 6 are defined by channel bars whose upper horizontal flanges are machined and serve as supporting surfaces for the installation of process units 7 and 8 which are made in the form of a drum-type drying furnace and a loading device. Other process units are not shown in the drawing in order to emphasize the elements directly related to the subject matter of the present invention.

Mounted on the bed plate is an electric drive motor 9 rotating a driving shaft 10. The driving shaft 10 is arranged along the longitudinal axis of the bedplate throughout its length, being mounted in supporting bearings 11 installed in the end face walls 3 and 4. The kinematic linkage of the driving shaft 10 (FIGS. 1, 3) with the electric drive motor 9 is through a friction clutch 12 (FIGS. 1, 2), a worm gear drive 13 (FIG.2), an overrunning clutch l4 and a gear drive 15 (FlG.3). The gear drive 15 consists of replaceable spur gears which set the required speed ratio of the gear drive to suit the operating cycle of the automatic processing line.

Located on both sides along the driving shaft 10 (FIG. 1) are cross members 16 defined by channel bars secured at one end in the end face walls 3 and 4. The vertical walls of the channel bars 16 are machined and serve as datum surfaces for the installation of coupling units 17. Each coupling unit 17 includes a single-jaw coupling 18 (FIG.4) with an electromagnet 19 which controls engagement and disengagement of the coupling 18, and an irreversible coupling 20. The couplings 18 and 20 are interconnected rigidly by a bevel gear drive 21. Output shaft 22 of the coupling unit 17 can be connected with the process units by means of suitable transmission mechanisms, for example a cardan shaft 23 (FIG.1). Mounted on a shaft 24 (FIG. 4) of the coupling unit 17 is a gear wheel 25 meshing with a gear wheel 26 installed on the driving shaft 10. The gear wheel 26 is mounted on the shaft 10 by means of splines and a lock screw (not shown) so that said gear wheel can be moved along the driving shaft and fixed in any desired position. The coupling units 17 can be installed on cross members 16 in any point along the axis of the driving shaft 10 and on any side of said shaft. To ensure the required direction of rotation of the process units, the coupling units 17 can be installed on either side of the shaft 10 and be turned to one of the positions at 180 with relation to the output shaft 22. In addition, the required direction of rotation can be obtained by shifting the gear wheel 27 of the bevel gear drive 21. The ends of the driving shaft 10 are provided with couplings 28 (FIG.1) which can be extended beyond the outline of the bedplate and fixed in this position after connecting them to the driving shafts of the jointed bedplates. The end face walls of the bedplates are provided with tie rods 29, supporting rollers 30 and adjustable supports 31. The bedplate has a force-feed lubricating system comprising a pump 32 actuated by a cam 33 secured on the driving shaft 10. From the pump 32, the oil is delivered through a pipeline 34 to a distributor 35 from which it can be fed to any lubrication point through pipelines 36. Also, mounted on the bedplate, along its longitudinal axis are water pipes 37, air pipes 38 and pipes 39 for feeding oil to the hydraulic pneumatic systems.

The above-described bedplate with a drive mechanism can be readied at a short notice for the installation of the process units of the automatic processing line. Such a bedplate can carry the entire automatic line if its length and the number of process units allow this. While designing such an automatic line, it is necesssry to select the transmission mechanisms for each process unit depending on the required speed of the working tool, and to determine the most rational arrangement of the process units on the datum surfaces of the bedplate. Then it is necessary to determine the arrangement of the coupling units 17 along the length of the driving shaft 10 to suit the location of the process units and the required direction of rotation. Having linked kinematically the driving shaft 10 with the process units, it is necessary to connect the lubricant feed pipes 36, water pipes 37, air pipes 38 and the pipes 39 feeding oil to the hydraulic systems. Thus, the bedplate realized in accordance with the present invention makes it unnecessary to design the bedplate proper with its drive mechanism and enables it to be made on the centralized basis, regardless of the designing and manufacturing stage of the process units. The drive mechanism of the above-described bedplate ensures synchronous operation of all the process units of the automatic processing line and allows, if necessary, accurate stopping of any process unit which is made possible by the use of the irreversible coupling 20. The single-jaw coupling 18 ensures starting of any process unit in accordance with the preset operating cycle of the entire automatic line. The coupling unit 17 also ensures simultaneous starting of a group of process units in accordance with the preset operating cycle. Thus, the present bedplate with the drive mechanism is universal and is highly convenient with regard to adjustments and servicing in operation.

In case of a very long automatic line, the process units can be mounted on a number of bedplates. The bedplates are jointed together by rigid tie rods 29. This jointing is simplified by the supporting rollers 30 and adjustable supports '31. After fastening of the bedplates, the couplings 28 are extended for joining the driving shafts 10. All the drive mechanisms of the jointed bedplates are interconnected rigidly and rotate at the same speed, thus ensuring synchronous operation of all the process units in the automatic line. The torque transmitted by the drive motors 9 is equalized by the friction clutches 17. The pipelines of the jointed bedplates can be coupled by the pipe fittings, forming a single centralized piping system.

Thus, the bedplate with the drive mechanism according to the invention ensures conditions for a maximum standardization and typification of the automatic lines which makes it possible to evolve base designs of machines for definite purposes and ensures their repeated employment.
