Method and device for making records or the like .

The invention relates to a method and a Device for compression molding, in particular a method and a device for producing records or the like.

Records are usually made in a press or die with two mold halves, one of which is fixed and the other is adjustable and retractable in relation to this, made. The two mold halves are designed as a hollow body into which steam and water can be introduced according to the requirements of the pressing process. The pressing surfaces of the two mold halves have the approximate For »indentations corresponding to the record or out« take shape while the final shape and sound record through a thin metal die that marks the recess of the mold half. " covered, determined. The press comes with a

thermoplastic molding material is supplied by an extruder, which the material (which is usually in granular or powdery form is delivered). Often gas is trapped in the molding material during the extrusion or pressing process, creating imperfections or imperfections in the finished record. After the thermoplastic molding material between the two halves of the mold have been pressed together with the corresponding record labels, the finished one will be Record pulled out of the press - a process that is often difficult because the record is tilted shows hanging on one or both mold halves. Next, the "ridge" from the edge of the plate, i.e. the one at the Pressing process from the depressions of the mold halves pressed out excess molding material are removed. Eventually be the finished records are stacked and, if necessary, packed. The above steps in making Records are time consuming and require a significant amount of human labor.

The invention has therefore set itself the task of avoiding the above-mentioned difficulties of the conventional record production process.

For this purpose, a method and a device for the automatic production of records are to be created according to the invention.

Further, an improved device is to be specified, the rapid and safe detachment of the record

109844 / 1280-

made possible by the mold halves of the press.

Furthermore, a novel method and a device are to be specified, the choice of a single Picks out the label from a stack of labels.

In addition, a new and improved method and a device for automatic trimming are intended specified on the record.

The stated and other purposes and advantages are achieved according to the invention by means of a method which comprises the following steps: The first step is to place two record labels spaced apart in the Extruder are introduced, which then presses out a batch of molding material between the two labels. For example Embodiment of the method is the nozzle of the The extruder is ventilated during the extrusion of the molding material in order to prevent gas from being trapped in the molding material. as Next, the molding compound with the labels applied on both sides is transferred to the molding press, whereupon the press is switched on and begins the pressing process. When the two mold halves of the press are separated, the pressed record becomes detached from these and then fed to a trimmer, which removes the burr from the periphery of the plate. Finally, the finished record is stacked, so that a stack with the desired number of records after one Packaging station can be transported.

109844/1280

This process sequence / can be automated,

by triggering each step by the previous step. For example, at an appropriate time indicated in the pressing process of the label conveying device that they are to supply the extruder with the next pair of labels Has. In this way, the production of the records takes place without interruption as long as the extruder and the label conveying device are supplied with molding compound or labels. Furthermore, in the case of the following to be described exemplary embodiment of the device two compression molding presses are operated automatically, each press having a corresponding one of the record in question Label pair is supplied.

find, each of the suction plates 28 and 29, depending on the position of the gripper arm 25 * of each of the stack pairs 21 or 23 each have a label.

A conveying device 33 has a conveying arm 34, at one end of which a suction plate 35 is arranged, the lower surface of which (as a whole in FIG. 4A) is provided with suction openings. The suction plate 35 is connected to a suitable vacuum system (not shown) via the arm 34 and a line 36 * \

The conveyor plate 35 can be extended by a motor 37 and a drive spindle 38 so that they are to rest against a Extruder 39 comes, the nozzle 40 of which protrudes through an opening 4l in the conveyor plate 35 when the conveyor plate is on the extruder is applied as shown in Fig. 4A. When the conveyor plate is in contact with the extruder, a pair of labels can be attached to the suction plates 28 and 29 has been passed through the gripper arm 25 the motor 26 can be pivoted into a position in which the suction plates are directly below the conveyor plate 35 (FIG. 9). Then the vacuum system for the label gripper is switched off and the vacuum system for the conveyor 33 is switched on, whereupon the label hanging on the suction plate 28 is transferred to the conveyor plate 35 and that from the suction plate 29 held label by a separating spring 42 (Fig. 9) arranged on this plate against a pressure plate 43, which is mounted so as to be movable back and forth under the extruder 39, is pressed.

109844/1280

After the pair of labels from the suction plates 28 and 29 has been passed, the gripper arm 25 is taken from the extruder 39 pivoted away, whereupon the extruder is switched on, so that there is a batch of molding material between the two Presses out labels. The pressure plate 43 is then, for example, by a suitable hydraulic drive (not shown) raised so that they put the molding material between the two

fc labels to form a single mass or package that can be received by the conveyor plate 35, pressed. This in Fig. 2 and 4A at 44 indicated by dash-dotted lines resembles a biscuit in appearance, in that the molding compound is sandwiched between the two labels.

The pressure plate 43 is then lowered, wherein the biscuit 44 through the one connected to the conveyor plate 35 Vacuum system is held on this. The conveyor plate carrying the biscuit is then driven by the motor 27 from the extruder withdrawn into the position indicated by dashed lines at 45 in FIG. 1

™ and the conveyor 33 is driven by a shaft

47 and suitable control cams operating motor 46 as long as e.g. pivoted against the press 24 until the conveyor plate at

48 reached position indicated by dash-dotted lines. The motor 37 is then energized so that the conveyor plate 35 (and the biscuit) is extended into the position shown in FIG. 2, centered directly above the lower mold half of the press 24. That The vacuum system of the conveyor is switched off so that

Label gripper.

The Etikettenaufgreifer 20 (s. Pig. 4A, 5, 6, 7 and 8) has a frame 65 having an upper plate 66, a lower plate 67 and two side plates 68. The right and linksgängie feed screw 31 is in the upper plate 66 and the lower plate 67 rotatably mounted by means of bushings 69 and 69 * fastened thereon, with two sleeves 70 and 70 * fastened on the feed screw 31 preventing their axial displacement with respect to the frame 65. The feed screw 31 can be rotated in both directions by the motor 32, which works via a pinion 71, a gear 72 and a coupling with a coupling disc 73 made of, for example, leather, a pressure plate 74 and a thrust washer 75 pressing against a shoulder on the feed screw 3I. The gear wheel 72, the thrust washer 75 and the feed spindle 31 are pressed into a drive connection with one another by a compression spring 76, the spring force of which can be adjusted by means of two nuts 77 screwed onto the feed spindle 31.

An upper loading plate 78 is attached to a threaded adjusting nut 79 by means of a plurality of screws 80 attached, which is screwed onto the upper part (with right-hand thread) of the Borschubspindel 3I. A lower pallet

1098U / 1280

8l is fastened by means of a plurality of screws 85 to a threaded adjusting nut 82 which is screwed onto the lower part (with a left-hand thread) of the feed spindle. The two loading plates 78 and 81 can in this way, depending on the direction of rotation of the feed spindle Jl, be moved towards one another or away from one another. Rotation of the loading plates 78 and 81 is prevented by two guide pins 84 and 85 (FIG. 4A) which are fastened on the upper plate 66 and the lower plate 67 and slide in two sleeves 86 and 87 which are attached Loading plates 78 and 8l are arranged and provided with suitable bearings in their interior.

On the Uhterface of the upper loading plate 78 are two label holders 88 and 89 arranged, while on the surface of the lower loading plate 8l two label holders 90 and directly opposite the holders 88 or, respectively, w. 89 and turned against them are arranged. The holders 88 and 90 receive the stacks of labels 21a and 21b, respectively, while the holders 89 and 9I the Pick up stacks 23a or 23b. Each of the holders 88, 89, 90 and ( 91 has a base plate 92 suitably fastened to the corresponding loading plate and carrying a plurality of bolts 93 on which a retaining ring 94 is releasably attached, which by corresponding Twisting with respect to the bolts 93 tightened or loosened can be. The retaining ring is secured against accidental detachment from the bolts by means of several screws 95.

In each label holder, a pressure plate is held by a pressure plate that engages the corresponding base plate 92

10984W 1280

Compression spring 97 pressed against the corresponding stack of labels. The stack is in this way against the retaining ring 94 pressed and by an inner annular surface 98 (Fig. 6), the sloping away from the corresponding bottom plate 92 inwards is held. The one removed from the bottom plate 92 Part of surface 98 has a serrated profile to ensure that the suction plate 28 or 29 of the Greiferarraes 25 each always .n’t remove a label from the corresponding stack. The labels have the usual central round hole 99, and a bolt 100 attached to the base plate 92 prevents sideways shifting the stack. The bolt 100 does not penetrate the entire stack, and several lateral guide pins on the ring 94 ensure that the stack concentrically in the Annular surface 98 is introduced.

The gripper arm (Fig. 6) has an upper suction arm 102 and a lower suction arm I03, which by means of several screws 104 are sealingly joined together. The upper suction arm has several openings 105 at the label gripping end as well as a further opening 106 into which a pipe section 107 is screwed, connected to line JO and with a suitable one Vacuum system (not shown) is in communication. The lower suction arm 103 has several openings 110 at the label gripping end and a recess which forms an elongated channel 108 which is connected to an annular channel leading to the openings 110 109 is in communication, so that the openings I05 and 110 via the channels 108 and 109 and the line j50 with the

109844/1280

Vacuum system of the label applicator are connected.

The lower suction plate 29, which has several openings, is fastened to the lower suction arm 103 by means of several screws 111 112, which are in communication with two annular channels 113 and 114, of which the channel 113 with the openings 110 is connected. The lower suction plate 29 has a central bore 115 in which a lower centering pin 116 with a Annular groove 117 for supporting and holding the separating spring 42 is arranged.

The upper suction plate 28 is similarly provided with a plurality of openings 118 which have two annular channels 119 and 120 are connected, of which the channel 120 is connected to the openings 105 »in a central bore 121 is an upper centering pin by means of a socket 123, a Spring 124 and a sleeve 125 resiliently mounted.

Furthermore, an inner seal 127 and one are on the upper vacuum plate 28 by means of a plurality of screws 126 outer seal 128, both made of a suitable material, preferably silicone rubber, a transfer suction plate 129 and a cover suction plate 130 (Fig. 7). The transfer suction plate 129 has several radial slots 131 * which from Plate circumference inwards up to one of the ring canal II9 overlapping point, and the plates 129 and 130 bind preferably soldered together, so that the radial base I3I channels form that the periphery of the transfer suction plate 129 with the vacuum system of the label pick-up connect and terminate in several suction openings 131a.

109844/1280

The outer edge of the upper suction plate 28 forms a protruding annular flange Ij52, so that the free part of the outer seal 128 is normally conical outwards from the upper suction plate (Figure 8). This ensures that the top label of the corresponding stack is actually picked up by the suction plate 28 when the vacuum system is switched on and the stack is positioned against the suction plate 28, the suction force of the top label generally along the ring zone adjacent to the edge of the cover suction plate 130 applied. In a similar way, an inner and an outer seal, a transfer suction plate with radial slots and a cover suction plate are arranged on the lower suction plate 29, which has a protruding annular flange I32 ^1.

Although the lower suction plate 29 is rigidly attached to the gripper 25 by means of the screws 111, the upper Suction plate 28 is loosely arranged on the upper suction arm 102. Two chambers 133 (Fig. 8) in the upper suction plate 28 take two on upper Saugami 102 attached visual hoods Ij54. Two between the heads of the screws Ij54 and two ring shoulders Γ36 Compression springs 135 ensure that the upper suction plate 28 is pressed against the upper suction arm 102. However, there is a certain amount of lateral play in the upper suction plate, its size through the annular space between the screws Ijj4 and the shoulders 136 is determined. Because of the possibility of Lateral displacement of the upper suction plate 28 compared to uem

109844/1280

Gripper arm 25. can align the upper suction plate by itself, so that when the two stacks of labels facing each other are gripped by the two suction plates 28 and 29, these two suction plates will be aligned with the corresponding stacks even if there is some misalignment exists between the two stacks. It is also important for proper alignment between the top Suction plate 28 and the extruder nozzle 40 provided.

The motor 26 (Fig. 4A) drives via a suitable one Drive mechanism with pinion, gear and clutch the shaft 27 in substantially the same way as the Feed spindle 31 is driven by motor 32. The gripper arm 25 is supported by the shaft 27 via an articulated arm 137 (Fig. 6) pivoted, which rests on a mounted on the shaft 27 bearing ring 138, with a disk wedge 139 for a ensures a perfect drive connection. The hinge plate I37 has a base part l40 and two eyelets l4l between which a hinge pin 142 by means of two screws 143 * penetrating the eyes l4l, their ends with the ends of the Scharrler pin 142 fit together, is stored.

The end of the gripper arm 25 remote from the suction plates 28 and 29 is forked into two arms 144 and 145 (FIG. 7), which engage around the shaft 27 in sliding contact and each have a hole receiving the hinge pin 142. In this catfish it is ensured that the shaft 27 is can not rotate relative to the gripper arm 25, while the

1 098A 4/1280

Gripper arm can rotate a little about the axis of the hinge pin 142. A leveling cam 146 with an inclined surface 147 (FIG. 5) is fastened to the base plate 67 by means of two bolts 148. A arranged at the lower suction arm 103 Noekenströßel 149 detects _v #fcn leveling cam 146, so that when the suction plates 28 and 29 between one of the two pairs of stacks are pivoted 21 and 23, they are located at the same level or parallel to the stacks, as shown in Fig. 4A , 5 and 6, while on the other hand they can be guided from this plane into other positions.

Furthermore, a locking cam 15O (FIGS. 4a and 5) is arranged on the shaft 27, which rests on a bearing ring 15I fastened on the shaft 27, a rotation between the locking cam and the shaft being prevented by a washer key (not shown). A latch pin I53 can be raised by a solenoid 152 (Fig. 5) of conventional design suitably positioned on top plate 66.

153 ρ den, which is pressed against the locking cam I50 by means of two springs 154 arranged on both sides of the pin, whereby a suitable opening is provided in the upper plate 66 through which the pin can penetrate. The locking pin 153 can engage in several holes 155 provided in the locking cam 150 so that the gripper arm 25 can be locked against rotation either under the extruder 39 or between one or the other pair of stacks 21 or 23.

Extruder and biscuit former

The extruder 39 (see Pig. 4A, 4B and 10) contains a heating chamber (not shown) from which successive portions or batches of a plastic molding compound can optionally be extruded or pressed by means of a suitable punch or a screw conveyor, as is well known. Preferably, the extruder 39 a automati- cally ä controlled Vorerweicher about the type as described in US Patent Application Serial No. 334,797 (filed December 31, 1963) by the same applicant. The extruder 39 has a plate 160 (Fig. 10) from which the nozzle 40 protrudes. The nozzle 40 preferably has a tapering part 40a, which facilitates its alignment with the suction plate 35, as well as a shoulder 40b of reduced diameter which can penetrate the central round hole of the label placed by the gripper arm 25.

Coaxially with the nozzle 40, the reciprocating pressure plate 43 is arranged, which on a shaft I61 is attached, for example by a suitable hydraulic system of conventional design, indicated at 162, is driven. The pressure plate 43 has a bottom plate 163, to which in a suitable manner, for example by screws (not shown), a suction plate 164 is attached, the several Has suction openings I65, which have an annular channel part I67 are in communication with a line 168 connected to a suitable vacuum system (not shown). The suction

109844/1280

Plate 164 has two curved spacer wings 169 and 70 which protrude from the periphery of the plate against the extruder 39, and two spring support pins 171 are arranged on both sides of the vacuum plate. Two tension springs 172 arranged between the pins 171 and two corresponding arms 173 attached to two movable tie rods 176 press the pressure plate 43 in the direction of the arrow (FIG. 10) against the extruder 39. The tie rods 176 are lowered when the molding compound is pressed out, so that the pressure plate 43 is withdrawn from the nozzle 40. This pulling off of the plate 43 prevents the nozzle 40 from digging into the molding compound while it is being pressed out, so that gas escaping from the nozzle 40, for example, is not trapped in the pressed molding compound and "bubbles" in the biscuit, which can lead to defects in the finished record can lead, form. In the case of an extruder with a punch, the tie rods 176 can, for example, be connected to the punch itself ψ . In the case of an extruder with a screw conveyor, the tie rods 176 can be lowered by a suitable drive mechanism if, for example, the screw conveyor motor is switched on. The extruder 39, the hydraulic drive 162 and the label picker 20 are mounted in a suitable manner on a main frame 174. Arranged on the vacuum plate 164 is a cylinder bolt 175 directed towards the nozzle 40 and oriented coaxially with it, the free end of which is tapered to facilitate the placement of a label and can protrude into the nozzle 40, as shown in FIG.

On the top plate 66 of the label gripper A limit switch 279 and a limit switch 280 are arranged by two on one on the upper loading plate 78 arranged cam rod 282 attached cams 28l can be actuated. Several mounted on the shaft 27 and in the cam control housing 285 arranged control cams actuate several in this Switches provided in the housing corresponding to the respective rotational position of the shaft 27 and consequently of the gripper arm 25.

If in the course of the respective pressing process that stage is reached in which the two halves of the mold Press 22 water is introduced, a temperature sensor switch 285 is closed and a relay coil 286 is thereby energized. (If desired, relay 286 can be connected through a normally opened manual switch 287 can be operated). The relay 286 remains independent of its holding contact 286a State of switches 285 and 287 energized until the normally closed contact 288f is opened. Usually Closed contact 286b is opened, causing the relay coil 289 operating in conjunction with the press 24 is de-excited.

The normally open contact 286c of relay 286 is closed, energizing the armature and field windings 290 and 291 of the stack motor yi and moving the two opposing stacks 21a and 21b against the suction plates 28 and 29 (the gripper arm 25 is normally) on the Stack 21 hired) until the normally closed

109844/1280

Limit switch 28Oa opened and thereby de-energized the stack motor will. (The stack motor can be switched off using the normally closed manual switch 292, if desired will.)

The normally open limit switch 280b is closed, causing the stack motor reversing relay 293 is excited, which remains excited via its holding contact 293a. The normally closed contacts 293b and 293c become open and normally open contacts 293d and 293e are closed, whereby the polarity of the field coil 29I is reversed, so that the stack motor, when energized again, rotates in the opposite direction and the stacks 21a and 21b pulls off the suction plates 28 and 29.

Contact 293f is also closed, energizing coil 294, which controls the vacuum system of the Engages pickup by suitable known means. if the desired negative pressure is reached, the vacuum sensor switch 295 is closed and the relay coil 296 is excited, which remains energized via its holding contact 296a. Before closing the switch 295, each of the suction plates 28 and 29 have picked up a record label so that the machine is shut down if in one of the two holders 88 and 90 the label supply is exhausted. After the suction plates 28 and 29 have picked up a pair of labels, the contact 296b is closed and thereby the stack motor 32 is excited so that the stacks are drawn off until the normal

109844/1280

Sometimes closed limit switches 279a are opened and thereby both the stack motor 32 and the reversing relay 293 are de-energized. Although the contact 29Jf is now open, the coil 29 ² I- remains energized via the closed holding contact 296a.

When the press 24 calls for water, the temperature sensor switch is activated 297 closed and thereby energized the relay coil 289, this relay also if desired

™ · can be operated by hand using a hand switch 298. Contact 289c is closed, causing the solenoid coil 152a and the armature winding 299 and the field winding 3OO of the motor 26 are energized, so that the locking pin 152 is raised and the gripper arm 25 counterclockwise from the stack 21 is pivoted away. (The normally closed switch 301a is open when the gripper arm is in the Position on stack 21.) The solenoid 152a and motor 26 can be operated by the normally closed hand

| switch 302 can be de-energized, and by means of switches 303 ^{and <} * J50 ^ the latching mechanism can be operated either automatically or by hand. The motor 26 runs until the gripper arm is engaged against the stack 23, at which point the normally closed switch 305a is opened . The switch 305b is then closed, is energized so that the stack motor, and thereby the staple are guided 23a and 23b in the manner already described to the suction plates 28 and 29 and away from.

109844/1280

When the stacks 21 and 23 return to the detached position, the switch 279b is closed, whereby the switches 301a and 305a are bridged by the contact 296d being closed as soon as the pick-up device is subjected to the necessary negative pressure. The motor 26 is now energized and the gripper arm 25 is pivoted away from the stack pairs 21 and 23, the cam follower 149 passes over the inclined surface 147 of the cam 146 downwardly, resting on the base l40 of the pivot plate 137 to the% gripper 25 'which the rotation of the arm into the position under the extruder is facilitated. The arm is pivoted into a "dwell" position between the stack 23 and the extruder 39; in this dwell position, the normally closed switch 306 is opened. When the feed plate 35 is then adjusted to detect the nozzle 40 in the manner shown in Figures 9 and 10, the switch 307a is closed; if the conveyor plate 35 is not subjected to negative pressure, λ the normally closed contact 308b is also closed, so that the switch 306 is bridged and the gripper arm 25 can pivot further into its position on the nozzle.

Before the arm reaches its position on the nozzle, the switch is closed 309, and thereby the coil l62a energized for the hydraulic drive, so that the pressure plate 33 SSEH by suitable known means P & driven down · (The normally open switch 310s is CLOSED

sen, when the feed arm J> K is at the nozzle. If desired, the hydraulic drive 162 can be switched off by means of the manual switches 311a and 311b.) When the pressure plate 43 is lowered, the gripper arm 25 pivots on the nozzle, at which point the switch 312 is opened and thereby the motor 26 and the solenoid 152a are de-energized .

The switch 313a is also opened, whereby the solenoid l62a is de-energized, whereupon the pressure plate the suction plate 28 by the action of the springs I72 (Fig. 9) makes contact with the conveyor plate 35. At the same time, the switch 313b is closed and thereby the reversing relay 288 energized for the pickup motor; relay 288 remains energized through its hold contact 288a. Contacts 288b and 288c are open and contacts 288d and 288e are closed so that when the motor 26 is re-energized, the ßreiferarm 25 pivoted clockwise away from the extruder will. Contact 288f is also opened, de-energizing relay 286 and / or relay 289, if previously energized will.

When the suction plate 28 is placed against the conveyor plate 35, the switches 3l4a and 3l4b are closed or opened, whereby the coil 294 for the vacuum system of the The pickup is de-energized (and thus this vacuum system is switched off) and the coil 315 for the vacuum system of the conveyor is energized will. When the top label is properly transferred from the suction plate 28 to the conveyor plate 35, the

109844/1280

Vacuum sensing switch 316 closed and thereby the relay 508 energized for the vacuum system of the conveyor plate; this relay remains energized by its hold contact 308a. When the vacuum system of the gripper is switched off, the lower The label is pressed by the spring 42 from the lower suction plate via the mandrel 175 onto the pressure plate 43.

Contact 308c closes and drives the pressure plate down with switch 309 still closed is. Contact j5O8d is also closed, ™ whereby the solenoid 152a and motor 26 are energized so that the gripper arm is pivoted until it is again reaches its position on the stack 21 and the limit switch 501a is opened. (The switches 505a and 305b for the stack 23 are during the pivoting back of the gripper arm 25 out of order because they are operated by a one-way roller, which acts on the movement of the gripper arm 25 in a clockwise direction does not respond.) Bejjn pivoting back of the gripper arm 25 The switch 309 is opened by the extruder 39, so that the pressure plate 43 can be raised by the springs 172.

By pivoting the gripper arm 25 clockwise also the switch 317 is closed, which does not respond to the counterclockwise pivoting of this arm; thereby the solenoid coil 318 for the extruder, the relay coil 319 and the coil 320 for the vacuum system of the Pressure plate energized, holding contact 319a keeping these relay coils energized. (Contact 308e is when applied the conveyor plate 35 closed with negative pressure. Through the

109844/1280

normally closed manual switch 321 can control the extruder solenoid de-energized if desired,) When using an extruder with a reciprocating punch the plunger is pressed down by the excitation of the coil 318, so that a batch of molding compound is pressed out through the nozzle 4o. This ensures that the molding compound is pressed out Vacuum on the pressure plate to hold the lower label on the pressure plate 43. The extruder 39 can If desired, they can be cleaned by turning the manual switch 322 with the gripper arm 25 engaged with the stack 21 (whereby contact 301b is closed) closes.

When the extruder ram begins to go down, the upper limit switch 323a is opened, causing the Solenoid l62a for the hydraulic drive is de-energized. The tie rods I76 follow along with the extruder punch below, whereby the springs 172 are relaxed, so that the pressure plate 43 during the extrusion of the molding compound from the Nozzle 40 can be withdrawn. This ventilation of the nozzle during the extrusion of the molding compound prevents the formation of Bubbles in the biscuit, as already explained. (Switch 323a is opened before contact 288g is in its normal position closed position returns, which only happens when the gripper arm 25 pivots back to the stack 21.)

If the vacuum on the conveyor plate fails during the extrusion process, be it because the vacuum system of the conveyor fails or because the upper label is due to the

1098U / 1280

pressed molding compound is pushed away, the contact reverses 308f returns to its normally closed position, energizing hydraulic drive solenoid l62a and the pressure plate 43 is lowered because the contact 319b is closed during the extrusion process. As will be explained later, the sensing switch 324a is open when No biscuit is present on the conveyor plate 35, so that the conveyor plate 35 does not move out of position in this case can be pulled off the nozzle. The error is therefore noticed immediately and corrected without further ado.

At the end of the stamp stroke, the lower limit switch 325 is opened, whereby the relay coil 318 for the hydraulic drive, the relay 319 and the relay coil 320 for the vacuum system of the conveyor are de-energized. The contact 319c returns to its normally closed position back, thus the relay coil is closed l62b (assuming that the conveyor plate acted upon by negative pressure, and the contact ¹ 3O8g is closed), and the pressure plate 43 is under a force of, for example, ungefähr45kg (100 pounds) pressed upwards, whereby the two labels and the molding compound are pressed into the desired biscuit-shaped package, which can be easily transported by the conveyor plate 35 (Pig x 10), the mandrel 175 piercing the biscuit in the middle. The extruder ram is returned to its original position by any known means (not shown), with the upper limit switch 323b being deactivated.

Excitation of the relay coil l62b open and the limit switch 323a are closed with the excitation of the relay coil l62a, whereupon the pressure plate 43 is lowered (provided that that the conveyor plate is subjected to negative pressure and the contact 308h is closed).

When the pressure plate 43 finishes its downward stroke the limit switch 326 is closed, causing the armature winding 327 and the field winding 328 of the motor 37 are energized because the manual switch 330 is closed and the sensing switch due to the presence of a biscuit on the conveyor plate 324a are closed. When the conveyor plate 35 is placed against the nozzle, the extension limit switch 20Oa is opened and the switch 200b closed, causing the reversing relay is energized (which remains energized by hold contact 329a), so that contacts 329b and 329c open and the contacts 329d and 329e are closed and the conveyor plate 35 is detached from the nozzle by the action of the articulated lever 197 (FIGS. 4A and 4B) and is retracted until the Limit switch 201a is opened and thereby both the motor 37 and the reversing relay 329 are de-energized. (The field winding 328 is now switched in such a way that the conveyor plate is extended when the drive motor is excited.) If off some reason the vacuum on the conveyor plate 35 while

ge
this will return / drive from the nozzle 40, fails so that the normally closed sensing switch 324b closes again, the closed contact 329f prevents the

1098U / 1280

Switch 201a is bridged. The switch 201b is also open, so that the pressure plate 43 by the spring 172 so far can be raised so that the mandrel 175 closes the nozzle 40, preventing leakage or "dripping" from the extruder will.

Switch 201c is also closed, energizing solenoid coil 184a for the latching mechanism and energizing armature winding 331 and field winding 332 of motor 46 by closing contact 308i and manual switch 333. The pivoting direction of the conveyor arm 33 is determined by the reversing relay 33 ^. 1, 'hen the relay 33 ^ is de-energized, the conveyor arm 33 is swung against the press 22 (corresponding to the stack 21), where the limit switch 335a is closed and thereby the reversing relay is energized so that the conveyor arm 33 can pivot back ^{to the nozzle.} When the press 24 calls for water and the relay coil 289 is energized, the contact 289d is closed during the duty cycle of the gripper arm 25, and during the counterclockwise pivoting of the gripper arm 25, the switch 336a is closed, whereby the relay 33 ^ is energized. This relay remains energized via the holding contact 334s, since the switch 336b is opened and closed while the holder 336a remains closed. The switch 336b ensures that the relay 336 is de-energized during the pivoting of the gripper arm 25 if the relay 289. The switches 336a and 336b are operated by a one-way roller to rotate them clockwise

The normally closed press limit switches 3O4a and 34la prevent the conveyor arm 33 * from pivoting when the presses 22 and 24, respectively, are closed (i.e. the two mold halves are touching), and the normally closed Switches 342 and 343 prevent the front arm from pivoting 33 if the gripper arm 49 'or the gripper arm 49 is pivoted into the press 22 and 24, respectively. Contacts 334f and 334g prevent the press associated with the inactive press Switches bypass the switches assigned to the respective active press.

After the conveyor arm 33 in the press 22 or the Press 24 has fluctuated, the limit switch opens 335b and limit switch 337b, respectively, thereby de-energizing solenoid 184 and motor 46. The corresponding limit switch 335c or 337c also closes, whereby the motor 37 is excited via the closed sensor switch 324a, provided that that the biscuit is still on the conveyor plate. The conveyor plate 35 with the biscuit is in the desired Press extended until limit switch 200a opens, at which point limit switch 200b closes is so that the Umst.euerrelais 329 is energized and thereby the conveyor plate 35 can be moved back. if the conveyor plate 35 has been extended into the press,

The normally closed detection switch 324b and the limit switch 338b (which is active only at the press) be bought ä closed, so that the motor energized 37 and the feed plate is moved back by the press until the limit switch 201a opens. When the conveyor vacuum is switched off, the contact 308j is closed, and when the conveyor plate moves back, the limit switch 200c is closed, so that the conveyor arm 33 is pivoted to the nozzle, where the limit switch 310b opens.

When the conveyor plate 35 is not subjected to a vacuum, the normally closed contact 30Öf becomes again closed, thereby energizing the hydraulic drive solenoid 162a and lowering the pressure plate 43; at the When the conveyor arm is pivoted back to the nozzle, the switch 310c is closed, whereby the conveyor plate 35 is in the position is extended under the nozzle (Fig. 4b) and then placed against the nozzle by the articulated lever 197. If the Conveyor plate 35 is placed against the nozzle, the limit switch 200b is closed, whereby the reversing relay 329 is energized and the motor 37 is enabled to drive the conveyor arm 33 after the next batch of molding compound has been extruded

to drive back. With conveyor plate 35 placed against the nozzle the switch 307k is opened and the solenoid l62a is de-energized, so that the mandrel 175 is raised by the springs I72 and the nozzle clogs to prevent any dripping of the molding compound.

When the conveyor plate 35 is extended into one of the two presses, the extension limit switch 338c is closed and, with the conveyor arm 33 engaged with the press 22, the switch 335d is closed so that the relay 345 for the hydraulic drive of this press is energized (and via the holding contact 345a remains energized.) Thereupon the hydraulic drive 231 is switched on by suitable means, so that the lower mold half 229 is placed against the upper mold half 216, beforehand? st that two suitable safety switches (not shown) in the press drive circuit are closed and indicate that the gripper arm and conveyor arm have been withdrawn from the press. The press then performs its pressing operation under the control of any suitable conventional control circuit (not shown) and when the lower part of the press is lowered the limit switch 3 ^ 0b is opened. In a corresponding manner, when the conveyor arm 33 is placed against the press 24, the switch 337d is closed and the relay J> K6 for the hydraulic drive of this press is thereby energized.

After a record is pressed, the lower part 228 is under the control of the press control circuit (not shown) lowered and the record through the spring-actuated ejector pins 222 out-: 1er upper Γ '.- itrize 2 L 9

pushed out. If desired, the ejector pins 222 can be actuated by suitable solenoid means which is energized or controlled by the signal from the press control circuit which causes the lower press section 228 to lower. When the lower press member 228 begins its downward stroke, the switch 350 is closed, energizing the armature winding 351 and field winding 352 of the gripper motor 53 and the solenoid coil 250a of the latching mechanism. The gripper arm 49 pivots in the counter-d-clockwise from its rest position on the stack 62 against the press, is closed again so that the switch 353 so that the gripper 49 further varies against the press, without regard to the state of the switch 350, operated by a one-way roller so that it does not respond to the upward movement of the lower press part 228. The solenoid coil 354 for the gripper vacuum system and the counter solenoid 355 are energized along with the gripper motor. As soon as the gripper arm begins to pivot, the switch 356a is opened with de-energization of the Abgrate- ™ relay 357 and the switch 356b is closed with the excitation of the solenoid 55a for the pneumatic lifting mechanism, so that the suction plate 5L, releasing the dome 234 on the lower mold half 229 is raised.

When the gripper arm 49 is pivoted into the press the limit switch 358a is opened, thereby shutting off the motor 53 and releasing the detent pin 252; Furthermore, the switch 358b is closed and thereby the reversal

Control relay 359 for the gripper motor energized via the Holding contact 559a remains energized. At the same time, the solenoid 55a de-energized, so that the gripper suction plate 51 can fall down on the pressed record, with a central opening 234a the mandrel 234 of the lower mold half receives in the suction plate. Switch 358 is also closed, causing the solenoid 360 is energized for the pneumatic mechanism, so that the Holes 239 are supplied with compressed air via the line 258 and the air jets emerging from these holes blow against the ridge of the record, so that the record is detached from the lower die 233 and easily can be removed from the press by the gripper 50.

When the desired negative pressure is applied to the gripper plate 51 (which indicates that the pressed Record is properly gripped), the switch 36I with activation of the pneumatic jack 55, the motor 53 and the detent solenoid 250a closed so that the gripper arm is raised and pivoted clockwise toward the trimmer 56 will. If desired, the gripper arm can be actuated of the manual switch 366 is withdrawn from the press independently of the negative pressure acting on the gripper plate will. The switch 353 operated by a one-way roller does not respond to the clockwise pivoting of the gripper arm. When the gripper arm 49 passes through the stacking position, the switch 356b is opened so that the record is in a horizontal plane is lowered in order to

For the automatic operation of the trimming motor 56, the switches 362a and 363 are closed and the switch 362b is open. If the trimming motor is to be operated by hand, switch 362a is opened and switch 362b is closed, the motor can be selectively turned on and off by switch 363.

When the gripper arm 49 is at the trimming station, the record is rotated by the gripping disk 58 (while being held in place by the suction plate 51) so that the burr is brought between the cutting disk and the traction sheave. The limit switch 364 for the trimming station is opened and the presence of the burr opens the burr sensing switch 365 so that the gripper motor 53 and the reversing relay 359 are de-energized. After the burr has been removed, the sensor switch 365 is closed and the gripper arm 49 pivots counterclockwise to the stacking station, where the limit switch 353 there opens. This de-energizes the gripper motor 53 and the solenoid 354, so that the trimmed record falls onto the stack.

At each duty cycle of the gripper 50, a suitable counter (not shown) is advanced one step by the counter solenoid 355, and after the desired number of sheet metal is stacked in the stack 62, a relay (not shown) in the counter will lower the contact 367a He-; 101844/1280
