one of those channels of each support (hereinafter referred to as "channel section") is used as a means for securing a binder string passing through a hole in the base of that channel section; the other channel section (hereinafter referred to as the "box section") is used to receive at least one lifting device for suspending the binder;
Additionally, a cover sheet of binder is attached to each of the elongated supports. In the assembled binder,
The box portions are both oriented in one and the same direction, and the channel portions are oriented in opposite directions and at a 90° angle to the direction in which the box portions are oriented.

The present invention provides a novel method and apparatus for manufacturing binders as described above.

According to the invention, there is provided a method for manufacturing a binder of the type mentioned above, which method comprises the following steps: Injecting a cover for the binder into an elongated receiving section provided on an elongated support, hereinafter referred to as unit strip. inserting a sheet and pressing the unit strip to close the receiving portion to secure the binder sheet to the unit strip and to form the holes necessary to receive the flexible string; punching out the base of the channel portion; forming a recess in the base of the box portion to position and maintain the at least one binder lifting device inserted therein within the box portion; The step of installing a support on the inside.

The present invention also provides an apparatus for producing a binder of the type described above, the apparatus comprising a plurality of acting means, which act to separate the elongated extruded strips into unit units.
cutting means for cutting into the lip and pressing means for pressing the strip into the unit 1 for fixing the cover of the binder within the unit strip;
punching means for forming the necessary devices at the base of the channel portion for receiving a flexible cord and an interior of the box portion for positioning and maintaining at least one binder lifting device within the box portion; An indentation means for forming a dent in the holder.

Before describing the method and apparatus for manufacturing the binder, it is necessary to briefly describe the extruded strip.

As shown in FIG. 1, the strip essentially consists of a channel portion 10. Box part 20. and a web or flange 30 connecting the two parts. The channel section 10 has a base 11 and an edge bear 12, and the box section 20 has a base 21 and an edge bear 22. The strip is formed from aluminum alloy by an extrusion process and cut to approximately 6111 lengths.

As shown in FIG.
Supply section 200 by rubbing. Press department 300. Punching section 400. Hollowing section 500, indexing section 600. They are a packaging department 700 and a packaging department 800.

A method and apparatus for the manufacture of binders will now be described with reference to the drawings. To begin the manufacturing process, a number (up to 180 in this example) of 6 m long extruded slips are placed in parallel at the loading station. The strips are moved laterally by rodless pneumatic cylinders and one of the strips is dropped onto a guide rail, with the channel portion 10 of the strip resting on the guide rail. Rodless pneumatic cylinders are well known and consist of a sleeve surrounding an elongated tube. A magnetic member is placed within the tube and is moved along the length of the tube by air pressure. A first photoelectric switch on the guide rail operates the rodless pneumatic cylinder when there is no strip on the guide rail. To begin production of the binder, a second photoelectric switch in the sawing station directs the pneumatic cylinder to advance the strip on its rail. As the strip advances, it fits onto a rail 40 that is machined with a groove 42 for receiving the edge 12 of the channel portion 10 (see FIG. 3). Parts of the machined rail 40 are made of nylon material and other parts are made of steel, and the steel parts are located in the process area. strip is second
As it passes under the photoelectric switch, a secondary feed vise grabs the strip and advances the end of the strip past the saw. The travel distance of the sub-feed vise is determined by mechanical stops and limit switches.

The positioning of the stops and limit switches determines the unit length of the strip as a binder. When the saw feed vise encounters the mechanical stop and limit switch adjacent to the saw, the holding vise in the saw station 100 acts to hold the strip. next,
The saw, which is a rotary saw, is moved and lowered into the pneumatic cylinder, which is a rotary saw, to cut the strip. is scrap and must be removed from the equipment.

On the next recycle of the saw feeding vise, the scrap portion is advanced to the scrap removal portion in the machined rail 1, where the rail 40 consists of grooves 42 that allow the strip to engage the rail 40. has been modified to remove. A flexible polypropylene member is positioned by the frame above the machined rails 40, which hold down the box portion 20 of the strip. The unit length of the strip is longer than its scrap-removed portion and is not machined. The slip 1~slip of the handle that is shorter than the unit length is
It is dropped from a machined rail into a scrap collection box. The length of the scrap removal section can be varied by removing or replacing sections of machined rail 40.

As the saw feed vises advance the uncut portion of the strip, their unit slips are advanced to a friction drive station 200 where electrical power is applied from below the machined rail 40. A plurality of friction drive rollers are provided which are driven by a motor and chain drive. The friction driven rollers align the unit-strips behind a gate vortex consisting of a gate fixed to a vertically mounted pneumatic cylinder. Once the friction drive station 200 is full of those unit strips, a third photoelectric switch senses when to stop the movement of those unit strips and pauses the sawing operation. A command is sent to the sawing station 100 as follows.

Advancement of those unit strips from said gate through the following three locations 300, 400° and 500 is:
This is achieved by four advancing clamps moving in synchrony. The positioning of the gate and advance clamp can be varied according to the physical length of the unit strip, and each unit strip is centered in successive sections.

Each advancement clamp has a single movable jaw and a positioning finger fixed to the jaw. Under the action of a pneumatic cylinder consisting of a pneumatic cylinder, the movable jaw slides laterally on a base member consisting of a base member for clamping one side of the unit strip, and a locating finger laterally slides behind the unit strip. move in the direction.

The jaw returns to its reset position under the action of a spring. Its base member is a machined rail 40
It is fixed to a shaft that is mounted parallel to the Its shaft and four advance clamps are reciprocated by a yoke driven by a pneumatic cylinder.

The saw feeding vise includes a pair of saws that are mounted on opposite sides of a machined rail 40. The jaws are closed by the action of a pair of pneumatic cylinders and are assisted in returning to their heard position by the action of a spring. The jaws slide on a base member that is slidably mounted on two fixed shafts that are mounted parallel to machined rails 40. The base member is reciprocated by a pneumatic cylinder independent of the advancing clamp.

When the first advancement clamp grips a unit strip, a gate is raised to advance the unit strip. As the first unit strip advances, it is held in position by a pinning device operated by a pneumatic cylinder comprising the next unit strip in line. When the gate is lowered, its pinning device is released and the next unit i...slip is advanced to the gate by friction driven rollers.

The unit strip gripped by the first advancing clamp is advanced to a press station 300 where a clamping device 310 operated by a pneumatic cylinder holds the unit strip in the pressing position. (FIG. 3). A binder cover 50 is introduced into the strip from in front of the press station 300. The binder cover 50 is
It is inserted into the recess between the flange 30 and the base 11 of the channel 10. The flange 30 is then pressed to secure the binder cover 50 between the flange 30 and the base 11 of the channel portion 10. Due to the shape of the strip, it is not possible to press the flange 30 in one independent operation. The press ram is therefore divided into two parts 320, 330, each part of the ram being driven by an eccentric. However, those two eccentrics are phased so that the fast flange part of the box part 20 first goes to the ram part 3.
20 to reduce the angle between the flange 30 and the base 11 of the channel portion 10. Then, the second portion 330 of that ram is located near the box portion 20.
Press down on the lunge to secure the unit sme-lip to the binder cover 50.

Once the breather culm is completed, the clamping device 31
0 releases the strip to its unit 1, and the 20th front 3
The fi clamp advances the unit slip and cover to the punching station 400, where the other unit slip is again pressed onto the machined rail 40 by the clamping device 410. It is clamped in the correct position (Figure 4). The holes necessary in the channel 10 for the function of the binder are formed by bunches 420 and dies 430, which pass through the machined rail 40 and emerge from below. those die 4
30 is attached to the platen -C,
It is lowered and locked into position using a toggle mechanism. The advantages of striking from below are that (1) no debris is created inside the channel 10 that might bite into the machined rail 40;
(2) the ability to use a large and therefore robust die 430; and (3) the ability to use machined rails 4.
0 acts as a stripper for the bunch 420.

Once the stamping process is complete, clamping device 410 releases the unit strip and a third advance vise advances the unit strip and cover to recess station 500. In this section, a pair of double indentations are formed in the base 21 of the central box section 20 along the unit lip, and a single indentation is formed at each end of the unit cell. It is formed. To provide the indentations, a double indenter bear and two single indenters are placed in the indentation station 500.To begin the indentation process, the clamping device fiR510 (fifth (Fig.) first clamps the unit strip to the machined rail 40, then three orthogonal pneumatic cylinders contact each of their recessing devices (Fig. The rear end device is then moved into the box portion 20 of the unit strip.
The depression die 520 is moved in the horizontal direction. When the recessing die 520 is in the correct position, four recessing bunches 530, which are indented from the pneumatic cylinder, act to press the base 21 of the box section 20.
Form and cover the necessary depressions.

Once the indentation process is completed, the clamping device 51
0 releases the unit strip and a fourth advance vise advances the unit strip and cover to the end of the machined rail. In the next cycle of the process,
The unit strip and cover are advanced to an indexing station 600 (FIG. 6). At the indexing station 600, a turntable has four arms. During each cycle of the process, the turntable 4 fixed process substations 620, 630, 640° and 6
50 are rotated by 90' to advance their arms through.

An overhead frame 610 is provided above the turntable on which a bowl feeder and pneumatic cylinder are mounted.

The first substation 620 of the indexing station 600 is the unit strip and cover supply substation, and the second substation 630 is the side-hanging loading substation. In the finished binder, it should have side-hanging eyes pointing in the same direction.

Therefore, each mutual unit of the binder set has 2
A side-hanging connection from a different one of the two bowl feeders 635 is provided. When attaching a side-hanging dowel to a unit strip, the dowel is pushed down into the box part 20 by one of the two pneumatic cylinders, and the rear end of the dowel is connected to the first pair. The eyepiece can be rotated about an axis transverse to the longitudinal axis of the strip.

Once the horizontal hanger mounting process is complete, the turntable rotates to the third substation 640 where horizontal hangers are attached to each end of each unit strip. Its horizontal hanging alignment consists of two bowl feeding devices 6
45 and is mounted by a pneumatic cylinder.

Horizontal hanging mats are installed on each single recess formed at each end of the strip.

When the horizontal hanging installation process is completed, the turntable will be placed in the fourth position.
