Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to packaging technology, and in particular to a carton magazine and its mounting device.

Traditionally, manufacturers of packaged goods had to purchase cartons that were creased and had their sides sewn together, and that the packaging machine operator manually loaded the cartons into magazines.

This is inconvenient when the carton is stored for a period that causes the carton to warp or curve, or when it is stored for such a period that it becomes in some way impossible to handle properly.

In the present invention, the creased carton is folded in a carton making machine, the sides of which are sewn together, and the creased carton is fed directly into the magazine.

Then pull out the carton from this and assemble it into a square:
The bottom is sealed and transferred to a packaging machine.

Therefore, there is no possibility that the cartons will change during storage, causing inconvenience when handling the cartons.

The carton is fed horizontally from a machine that stitches the sides of the carton.

Since the magazine of the present invention supports cartons in an upright position, equipment is provided for transferring the cartons to the carton magazine in a vertical position to form a horizontal stack.

During operation, the carton stack stands on a pair of chains, one of which is driven forward at each predetermined cycle of operation, causing the carton stack to move forward to compensate for the cartons that are withdrawn. It is moved towards the front of the magazine.

When the front side of the stack engages the stop, the chain frictionally engages along the bottom of the stack.

The receiving end of the stack is provided with a device for moving successive cartons forward to engage the back of the stack.

This forward movement also leaves a gap for the subsequent rounds to be transported from the side sewing machine.

Father, control means are provided to stop the production of cartons when the magazine is full of cartons.

Thus, one object of the present invention is to provide a new and improved carton magazine with a device for easily and efficiently receiving successive cartons from a carton making machine.

Another object of the invention is to provide a carton magazine equipped with a device for vertically feeding cartons discharged horizontally from a carton making machine to form a horizontal stack.

Another object of the invention is a means for interrupting the transport of cartons into the magazine when the carton magazine is full and means for restarting the transport of cartons when the magazine has been emptied to a predetermined point. To provide a carton magazine with

In addition, if a carton is not sent to the magazine within a predetermined time after a signal is transmitted to initiate the transfer, a device is installed to interrupt the operation of the entire device. It will be done.

To accomplish these general objects and objects set forth hereinafter, the invention resides in the carton magazine and in the claims appended hereto. It concerns various configurations, arrangements, and combinations of parts.

One of the connecting rods 84 is supported in a groove formed in the vertical member 58.

An intermediate member 86, which also has a groove, supports the other connecting rod 84.

At the top of the sloping section of the conveyor, the belt 24 follows a curved path defined by an idler roll 92 mounted on connecting rods supported between a plurality of angle brackets 96.

The angle brackets 96 are provided on a plurality of angle members attached to the vertical side plates 100.

One side plate 100 is attached to the sand rail 60 as shown.

The curved top rail 102 is supported above the idler roll 92 by a perpendicularly extending member 104 attached to the final end angle bracket 96 as shown.

Each member 104 is provided with a groove at its upper end for receiving a rod 106 that supports a tightening member 108.

A plurality of tightening members are positioned to receive a plurality of studs extending from the curved top rail 102.

After passing the idler roll 92, the conveyor belt 24
passes around pulley 110 to begin traveling downwards.

This downward running path passes above the idler roll 112 and below the idler roll 114 before returning to the drive pulley 926.

Idler roll 112 is rotatably attached to a bolt supported by the free ends of a plurality of arms 116;
The other end of the arm is a connecting rod 11 extending between the side plates 100.
8 is attached with bolts so that it can be adjusted freely.

The idler roll 114 is rotatably attached to a connecting rod 120 extending between inclined members 112 attached to the sand rail 60.

From the foregoing, the flat tubular cartons are sequentially transferred 6 from the carton making machine past the downwardly curved portion where they are placed prior to being placed in the magazine 16.

An auxiliary belt 124 is disposed between the spaced apart belts 24 to more actively feed the magazine downward.

As shown in FIG. 3, spaced pulleys 110 are secured to a shaft 126 which is connected to the side plate 126.
The belt 24 is rotatably attached to a bearing 128 supported by a shaft 126, and causes the shaft 126 to rotate.

Intermediate gooley 110 is also secured to shaft 126 and auxiliary belt 124 runs on pulley 130.

The belt 124 passes from the gooley 130 to the idler roll 132, pulley 134, and idler roll 136.
travels and then returns to pulley 130.

Thus, during operation of the device, the cartons pass through the spaced belts 24 to a single downward running path and then to the spaced chains of the carton magazine 16. Fall while standing on 18.

A top guide rail 138 is provided to prevent the carton from shifting upwardly during downward movement.

The rail is provided with a plurality of extensions supported by tightening members 140 attached to the connecting rods 142 and 106, respectively.

The connecting rod 142 extends between the groove portions of the side plate 100.

An idler roll 144 is provided to cooperate with the idler roll 132 to ensure that the cartons are delivered into the magazine for combination with the previously delivered cartons or stacks.

Idler roll 144 is secured to a shaft 146 which is supported by spaced apart arms 148 and is supported by a plurality of ball bearings.

The plurality of arms 148 have a shaft 152 that is journalled in a bearing 154 that is stopped in a groove portion 155 of the side plate 100.
The yoke 150 is bolted to a plurality of arms of a yoke 150 that is latched to the yoke 150.

A coiled spring 156 is supported at one end by a lever 158 which is latched to the shaft 152.

The other end of the spring 156 is connected to a spring loaded stud supported on the end of the connecting rod 160.

An idler roll 132 is rotatably mounted on this connecting rod 160.

The connecting rod 160 is adjustably supported in a groove portion 161 formed in the side plate 100 for adjustment to different sized cartons.

The shaft 152 and its clamp bearing 154 are also adjustable in grooved portions 155 for cooperating M with the rolls 132 and 144.

The continuously moving auxiliary belt 124 has rolls 144 and 132
run between.

The pressure exerted on the carton by the spring-loaded roll 144 cooperates with the back roll 132 to provide a more positive downward transfer of the carton into the magazine.

A guide rail 162, adjustable and supported on one side of the side rail 100, ensures alignment of one edge of the cartons that are sequentially transferred to the magazine.

A plurality of rotating brushes 164 are mounted on shaft 146 to further assist in the downward transfer of cartons into the magazine.

One of the brushes is equipped with rolls 144 as shown on both sides.

The plurality of brushes have a slightly larger diameter than the roll 144.

The spaced chain 18 includes a chain conveyor 166;
Cartons are placed on this chain conveyor and moved forward within the magazine.

The chains are arranged to run over a drive sprocket 168 at one end of the conveyor.

Multiple chains are connected to idler sprocket 1 at the other end of the conveyor.
Drive over 69.

The chain conveyor 166 has a long support added to the frame 172 and has suitable guides 17 for the chains 18.
4, and this guide is supported on the top of the support 170.

The magazine 16 has side rails 176 for the cartons between which upright cartons are guided as they advance toward the front end of the magazine.

In practice, the chains are caused by the drive means to undergo a small forward movement for each cycle of operation of the device.

This means includes a one-way clutch 178 attached to a sprocket 180.

A lever 182 extending from the clutch 178 is connected at its other end to a rack 13 slidably attached to the machine frame.
It is connected by an 8-helical link 186 to a rotor 184.

The rank is extended from slide rank 188 to 194
Eccentric member 1 connected by crank lever 192
90 for reciprocating movement.

The eccentric member is fixed to a shaft 196, which shaft is connected to the motor 20.
0 chain and drive sprocket 198.

Thus, during operation of the device, each reciprocation of the sliding rank 188 imparts a small rotation in one direction to the sprocket shaft 180 to advance the chain via the clutch 178, thereby slightly advancing the stack. .

The return movement of the clutch is designed to slip.

The carton 12 is pulled out from behind the stop 20 at the front of the magazine by known means.

This means has an arm 202 with a suction cup 204, which arm is swingably mounted.

Arm 202 is secured to a vertically supported pivot shaft 206.

The lower end of shaft 206 includes a gear 208 for cooperating with reciprocatable rank 188.

This allows the stop member 20 to
The carton is pulled out from the back side.

Suction and extraction means are provided for transferring the carton to assembly and sealing means, not shown.

A second eccentric member 210 on the shaft 196 is connected by a link 212 to an arm 216 secured to the shaft 216 journal-bearing in the machine frame.

A second arm 218 is also fixed to the shaft 216 and is connected to a sliding bar 220 added to the frame.

This rod 220 cooperates with a suction mechanism to pull and open the carton.

Referring to Figures 1 and 3, there is shown a device for pushing the upper edges of the upright cartons which have been transferred to the receiving end of the magazine and means for uniformly feeding the cartons into the carton opening means. Devices are provided to maintain the alignment of the top edges to ensure that.

As shown, a pair of rolls 222 are mounted on a yoke 224 that is rotatably supported in an arm 226 of a bracket 228 attached to the machine frame.

The periphery of each roll 222 has a surface of rubber or similar material for frictional engagement with the upper edges of the plurality of cartons.

The shaft 224 is coupled to the swinging arm 214 with a connecting link 230 extending between the lever 232 and the arm 214, so that it undergoes a small rotation during each cycle of operation of the device.

Lever 232 is coupled to a one-way clutch mounted on shaft 224.

Thus, during operation of the apparatus, the rolls in frictional engagement with the top edge of the carton cause the top edge of the carton to advance simultaneously with each cycle of chain 18.

The roll 222 is aligned by periodically tapping the top surface of the stack with a flat plate 234 that operates to align the upper edges of the plurality of cartons by pushing down the cartons that protrude above the alignment surface of the plurality of cartons. A device is provided for aligning the edges of the crossed cartons.

Flat plate 234 (circular here).

) is coupled to a piston of an air cylinder 236 which is adjustably locked to a rod 238 supported on the machine frame.

The air cylinder is connected by a conduit 240 to a valve 242, which in turn is connected by a valve 244 to a source of compressed air.

A normally closed valve 242 is attached to the bracket 228 and includes a roll carrying arm 246 for cooperating with the head of a roll 248 that is adjustably supported on one of the plurality of rolls 222 .

Because the roll 222 rotates a small amount during each cycle of operation of the device, the valve 242 is opened for tapping by the plate 234 periodically after a predetermined number of cycles. It's only when I get caught.

Referring to Figure 237, a device is provided for controlling the transfer of cartons 12 to the magazine so as to interrupt feeding when the magazine is filled to a predetermined point with cartons.

This is to prevent the successive cartons from jamming and to automatically start the transfer operation when a sufficient number of cartons have been removed from the stack.

This control means therefore serves to keep the size of the carton stack substantially constant.

Preferably, the speed at which cartons are fed into the magazine is slightly faster than the speed at which cartons are withdrawn so as to ensure a constant supply of cartons to the magazine.

As shown, a pair of spacers rotate on a shaft 252 supported between a plurality of arms 254 as the cartons are forced downwardly to join the ends of the stack. The last end carton engages with the roll 250 provided at the end.

The plurality of arms 254 are supported by the plurality of levers 256,
This lever is locked to one shaft 258.

The shaft 258 is supported by the plates 260, 2 supported by the side plate 100.
It is swingably attached to a bearing located at 62.

One of the plates 262 is a switch plate 268, 270, respectively.
a pair of switches 2 arranged to be energized by
It carries 64,266.

The plurality of switch plates are supported by the free end of a lever 272, which is locked to a swing shaft 258.

A coil spring 274 extends between a locking spring 276 and a stop screw 278 supported by lever 272, and the spring is connected to a stop screw 279 supported by a corner member 280 attached to plate 262.
The lever is arranged so that it can be pulled clockwise toward the

stationary stud 276
It is also attached to the corner member 280.

When the lever 272 swings downward, it causes the plurality of rolls 250 to swing toward the end of the horizontal stack while being regulated by the stop screw 279.

Thus, during operation of the apparatus, the plurality of rolls 250 swing slightly rearward as the carton is transferred to the receiving end of the stack.

As the stack expands rearwardly in this manner, the axis 258
swings counterclockwise, thereby swinging the lever 272 and the switch biasing plates 268, 270 provided thereon upward.

Both switches 264 and 266 are connected to the "side seam machine (
side seamer) controls the feeding of crumpled flat carton stock into a carton making machine, commonly referred to as a side seamer.

In this manner, during operation of the apparatus, a plurality of cartons 12 with their sides sewn together in the stack 15 are pulled out, and when the lever 272 rests against the stop screw 279, the motor circuit for feeding the carton material is activated. 282 is the 7th
It is closed by a switch operating plate 270 with switch 266 as shown.

As a result, feeding of the carton material to the side seam machine is started, and the seamed carton is transferred to the magazine 16.

A plurality of cartons are sequentially added to the stack 15, thereby gradually swinging the lever 272 upward as long as the transfer of cartons to the magazine 16 continues.

When the magazine is filled with cartons to a predetermined level and the switch operation plate 268 operates the switch 264, the motor circuit 282 is opened.

The speed at which sewn cartons are fed into the magazine is slightly faster than the speed at which cartons are pulled out from the magazine, so make sure to always feed the correct number of cartons into the magazine.
The feeding of carton material to the stitching machine is periodically started and interrupted.

Note that a device is provided for adjusting the switch operating plates 268, 270.

This is to change the time at which the carton material feeder 284 starts and stops feeding.

Further, a device for controlling the entire device is further provided.

This is to stop the operation of the entire apparatus by closing switch 266 when a situation occurs in which cartons are no longer being fed to the stitching machine.

In such a case, if the carton magazine is not refilled while the cartons continue to be withdrawn,
Cartons may jam inside the magazon.

To avoid this, a switch 266 is connected to a delay relay 286 to interrupt operation of the entire system if a hecarton in the magazine is not received for a predetermined period of time.

However, when the cartons are normally fed into the magazine within the above-mentioned time, the time relay is inactive, so the operation of the apparatus is not interrupted.

Usually, cartons are not fed into the magazine due to carton confusion in the material feeder, so this timed relay is used to prevent cartons from being fed into the magazine due to carton confusion in the material feeder. This is a safety mechanism that stops the entire device when a problem occurs, and a safety device that eliminates such trouble before restarting operation.

As mentioned above, regarding the feeding of carton materials, application number 813, filed on April 3, 1969 by the present applicant,
See No. 172.

In the basic wiring diagram, Figures 7 and 8, the stitching machine motor relay is numbered 285 (MI) and the line in Figure 7 is ■

0 (Mi), and 295 (R?).

Contacts 290 (Ml) in line 2 are closed by relay 285 (Ml) in line 1.

Contacts 295 (R7) in line 2 and contacts 296 (Rl) in line 3 are connected to the contacts 295 (R7) in line 3 when the cartons in the magazine are ejected and the stack shrinks to a predetermined point. When the switch 266 (SW2) is closed by the switch operation plate 270 as shown in FIG. 3, it is closed.

When switch 266 closes, relay 297 in line 3
(Rl) is energized and closes the holding contacts 295 and 296.

Line 4 has carton material feed motor relay 298 (
R2) is included.

This relay is connected to the holding contact 30 in line 4 as shown in Figure 8.
2 (R2) and the starting contact 300 for closing the plurality of motor contacts 304 (M2).

Relay 298 (R2) also connects contacts 2 in line 2.
93 (R2) and relay 2 shown in FIG.
92 (M2) to start the motor 305 for feeding the carton to the stitching machine.

As soon as the cartons in the magazine have been discharged to a predetermined point, switch 264 (SWI) is opened by switch operating plate 268 (FIG. 3), demagnetizing relay 297 (R1) in line 3, Relay 292 (M2
) in line 2 for demagnetizing the contacts 295 (Rl
).

The motor 305 is thus stopped and the feeding of carton material is interrupted.

Line 5 includes a plurality of holding contacts 310 (M3) and a motor relay 306 (M3) energized by a start button 308 to close a motor contact 312 (M3).

Motor 314 drives the chain of conveyor and magazine 1
Stand up the cartons in 6 and move them forward.

This chain is stopped by button 316.

Line 6 includes a delay relay 286 (TORI).

This relay opens normally closed contact 318 (TDRI) when a carton is not received from the seam machine into the magazine within a predetermined period of time.

As mentioned above, it can be seen that a novel apparatus is used to sequentially transfer a plurality of flat tubular cartons from a carton making machine to a carton magazine from which the cartons are sequentially withdrawn.

Additionally, devices are provided to control the feeding of cartons into the magazine to ensure constant feeding conditions and to prevent overloading and jamming of cartons.
