Device for setting up boxes

The invention relates to a door direction for setting up Folding boxes and relates in particular to an improved device! For holding flat, folded box blanks, which are briefly referred to below as boxes, and to transfer these boxes from their original collapsed State to a second state in the form of a tubular shape with open ends »

Known Schachtelaufstellmaschinen work quite satisfactory when 60 boxes operate on the correct setting for the four box sizes with the intended Ausstoß.von per minute ^ but the Single digit-machine 1st 'difficult and it has been found that then _p when the pitch mechanism with an output of around 75 to 100 boxes per minute should work »quite often boxes are erected imprecisely, which creates a jam that interrupts the operation of the machine until the jam is cleared *

009083/0080

It can also be seen that sometimes the front and rear walls the foremost box in the magazine tend not to detach from each other but to stick to each other when these foremost box is withdrawn from the magazine. When the walls of such boxes stick together, the boxes are "at." Down against the bending plate so stiffly that they are detach them from their suction heads when they hit the plate. Under A bending plate is to be understood as an obstacle located in the path of movement of the box, which is used to create a To temporarily inhibit the movement of the edge of the box, which is initially only slightly open, in order to open the box cross-section to the full opening or beyond the full opening to almost the opposite, flat Bring about state.

One tries to overcome the difficulty mentioned by that both parts of the rear wall of each box are affected as soon as the front wall of the box is gripped and lifted from the magazine will; Both ends of the box are partially opened at the same time, as soon as the box is withdrawn from the magazine will. The lower box edge, which runs parallel to the magazine and the bending plate, then turns down against the bending plate movesj, while at the same time opening forces of the same size over the overall length of the box can be exercised so that all four 'longitudinal edges of the box throughout the opening and closing The bending process run parallel to each other.

The invention is based on the box erecting device mentioned at the beginning, but has a magazine on which improved devices for easy setting and fixing of a wall [

009883/0080 ^!

of the magazine in selected positions to handle boxes of different sizes. A fast working one Suction head grips the front wall of the foremost box and pulls the whole box out of the magazine.

The invention consists in that additional devices on the magazine are provided, which are designed such that after the Initially, only pulling the box blank from the magazine one end of the box is opened, and that the opening movement continues to the other end of the box, if the distance of the box blank increases from the output opening of the magazine . . - ,.: _.

In a preferred embodiment of the invention is before Output opening of the magazine in the vicinity of the first to be opened shaft end arranged a fixed device which. is suitable for the forward movement of part of the back wall of the box of the box blank pulled from the magazine's output opening to slow down. The device for slowing down the forward movement of the part of the rear wall can be considered relative to the magazine fixed cylindrical stop pin formed be.

Thus, the zylindrische'Anschlagstift only touches an end of the rear wall of the foremost _en box, for which, preferably, the box end is chosen which forms the bottom closure. To this . One end of the box is partially opened shortly after it is pulled out of the magazine, the forces for partial opening being transmitted through the box walls from said one end to the other end and causing each other to gradually expand

which separates one wall from the other and the lower edge of the box from the bottom lock to the top lock tilts about 5 downwards against the horizontal, while the top edge of the box remains horizontal. When the box moves further into the deposit position, the lower inclined box edge touches the flat face of one in the same direction and in

same. Dimensions of inclined bending plate. The inclination of the bending plate runs in such a way that the entire length of the lower edge of the box touches the plate at the same time and when the movement continues of the suction head gradually opens the box from said one end to the other. Then the box will be complete bent over and pulled off the bending plate via a compensating rod, the upper edge of which runs parallel to the magazine floor, which causes both box ends to be bent over to the same extent. Then the box is removed from the suction head Released at the laying station in the erected state as a tube with open ends and rectangular cross-section before a new work cycle begins.

The invention thus provides a fast-working set-up device which causes a box to gradually open from one end to the other. The invention also has an improved one Device with which the magazine can be adjusted so that boxes of different sizes are housed and can be treated.

The invention is described below on the basis of an exemplary embodiment explained with reference to drawings showing the following:

The high-speed carton stand-up device 30 (FIGS. 1 and 2) according to the invention, a magazine 32 which is adjustable for different box sizes and which is mounted on a frame 34 rests and has an adjustment mechanism 36 with which one magazine wall can be adjusted relative to the other magazine wall, and a latching device 38 which can selectively latch in four positions corresponding to the four box sizes, see above that the locking of the magazine can easily be done in one of the four preselectable positions. A dispensing opening 40 is located at the lower end of the magazine 32; The removable boxes C are located at the opening.

A suction head 42 can be placed on the frame 34 from a withdrawal position Move P to a storage position D. The suction head moves after gripping the front wall 44 (Fig. 10) of the foremost box C in withdrawal position P away from the dispensing opening 40, so that a cylindrical stop pin 45 the rear wall 46 of the box contacts at one end, preferably at the end forming the bottom seal BG, after it has been pulled away from the opening 40; thus the front wall 44 moves away from part of the rear wall 46. Since the rear wall 46 is only gripped at one of its two ends, the rhombus-like opening that is

00 9663/00 8 0

telenden arises further at the attacked end than at that opposite end; it follows that the lower edge of the box move from one end of the box to the other less than 5 °.

At port settlement- the movement "touches the inclined lower chess- telkante 48 a bending plate 50, which in the same way from the bottom closure BC down towards the top closure IC of the box G slopes downward, causing practical the entire length of the lower edge 48 contacts the clincher plate 50, so that the box opens completely; During the joint opening process, the bottom seal is higher than the top one Closure. Bann is bent over the box by placing it over a Compensating rod 51 runs, which is attached to the bending plate 50 is screwed and its upper edge is horizontal. The box is thus over the entire length of the box folded down to the same extent before they are in the storage position by the suction head 42 D is released.

The magazine 32 (Figures 1 to TO-) can be adjusted so that four different box sizes can be handled; the preferred sizes are quart, pint, third quart and half plan boxes, indicated by in FIGS. 3 or 4 or 5 or 6 the boxes 01 or 02 or 03 or 04. The magazine 32 has an inclined subframe 52, which at its lower end by a cross bar 54 and at its upper end by a not shown Connecting part is rigidly connected to the frame 34. An elongated, fixed guide and support wall 56 (Figures 3 to 6) is with the subframe 52 by bracket 58, the one Form part of the wall, rigidly connected and has a support surface 59 V 0098 8 3/00 8 0

the end forming the bottom cover BG of the box the box slidingly picks up. The inside corner of the fixed Guide wall 56 is retracted at 60 to prevent the lower corner of bottom latch BC "from sliding downward of the boxes in the magazine is withdrawn.

• In addition, there is an adjustable longitudinal wall on the magazine 32 62, which is precisely aligned so that the top shutter TC 'can slide along her; this wall possesses just like that fixed wall 56 has a support surface 63, which is withdrawn at 64 is to prevent backward bending of the lower corner and the end faces of the upper shutter.

The adjustable wall 62 / slides on an upper cross bar 66 (Figures 1 and 2) along and on a lower slide bar 68, the is also rotatable and forms part of the latching device 38. The upper rod 66 (Figure 2) is by means of a not shown Snap ring that rests against the stationary wall 56 leans firmly connected to the subframe 52. A nut 70 screwed onto the other end of the rod 66 presses against the Side wall of the subframe 52 and fixed the rod 66 in his Location. '

A hub 72 (Figures 7 and 8) of the latch 38 is fixedly attached to the adjustable wall 62 and surrounds the rotatable one Rod 68 sliding freely; the rod 68 is secured by a nut 74 screwed onto one end of the rod and one onto the other end of the rod pinned switching disk 76 prevented from lateral movements, a pawl 77 is pivotably attached to a head screw 80, which is firmly seated in the adjustable wall 62; the handle is in

00908 3/00 80

a slot 82 in the hub and engages a specific one at a time of four grooves 84, 86, 88 and 90 cut into 'the rod 68-' th are. The grooves 84, 86, 88 and 90 are in the rod 68 "with mutual spacing cut in the longitudinal direction of the rod, so that the adjustable wall 62. are held precisely in the position in which you can put quart, pint, third quart and half pint boxes picks up when the pawl 77 has fallen into the associated groove is. A spring, 91 is between a pin 92 and the outer The end of the pawl 77 is unclamped and serves to hold the pawl in the to hold the respective groove. It should be noted that the four grooves are made in four different cross-sectional sectors of the rod are, so that the pawl is able to slide along the rod and can only fall into the groove which points upwards in the respective rotational position of the rod 68.

As mentioned, a feature of the invention is a latching device 38 which can be switched from one latching position to another. The switch 76 of the latching device 38 consists of an outer clover-shaped handle 76a and an inner disc 76b, in which the words "quart ¹¹ ," pint "," third quarter ¹¹ and "half pint": are engraved (see Fig. 9). A ball catch 93 or other locking device is recessed in the subframe and the ball engages notches in the disc 76b to hold the rod 68 in the selected rod sector, the box size designation being compared to a mark M on the bracket 58 and then one of the grooves 84, 86, 88 and 90 is rotated upward. To adjust the latch 38 out of one box size position and to another size, the rod is used

rur rotated in dia ftewUneohta position, with the operrkJluke

is lifted out of the previously valid groove (position indicated by dashed lines in Fig.7), so that the. sliding wall 62 can be moved into the position for the new box size, in which the pawl then falls into the associated groove and prevents further displacement of the adjustable wall.

In order to push the boxes in magazine 32 downwards towards the vent opening, a heavy pusher 94 (Figures 1 and Z) is slidably mounted on a pair of parallel guide rods 96. The ends of the guide rods are attached to carriages 98 and 100, respectively, which are slidably arranged on the transverse upper slide bar 66 and the lower slide bar 68, respectively.

A handle 101 (FIG. 2) is attached to the slide 94, which it it is easier for the operator to move the slide in the magazine 32 upwards to move, and a hook 102 that comes with a cap screw 103 is pivotally attached to the subframe 52, is placed over the handle 101 when a new stack of boxes is in the Magazine must be placed. With the slider 94 held away from the discharge end of the magazine, the operator can Put a supply of boxes into the magazine 32 more easily and precisely because he does not have to manually remove the slide from the boxes needs to push away.

In order to adjust the wall 62 and to keep the slide 94 in the middle between the walls 62 and 56, the magazine 32 is included a pair of transverse adjusting spindles 110 and 110a with double threads equipped (wing 2). The spindle 110 (Figures 3 to 6) has a small diameter portion 111; at the free A crank 112 is attached to this section. On one

Intermediate part 113 is see / a screw thread with medium-sized Diameter, and a large diameter section 114- "has a" screw thread, the pitch of which is twice as large like that of the thread on the middle diameter section » A sprocket 116 is attached to the section with a set screw 111 with a small diameter and cooperates with the hub of the crank 112 to prevent axial displacement of the spindle 110 with respect to the subframe 52. The middle piece 113 with ^ medium diameter leads through a threaded block 118, as can be seen in Mg.3, is screwed to the slide 98. Of the Large diameter section 114 engages through a bore in the adjustable wall 62 ^ and: leads through a threaded block 119 'which is screwed to the wall 62.

The other adjusting spindle 110a! Figures 1 and 2) is consistent with the spindle 110 in its construction and arrangement Convention _r only is provided instead of the crank 112, a collar piece 120th Around the chain wheel and a chain wheel 116a wedged on the adjusting spindle 110a is a; endless toothed belt 121 placed. To adjust the wall 62 and the slide 94, therefore, only the spindles 110 and 110a need to be rotated with the crank 112 in the wet direction, after the device 38 has previously been switched into the required blocking position and moved into the wall 62 must become. Since the pitch of the threads of the strong sections 114 of the two spindles 110 and 11Qa is twice as great as that of the threads on the intermediate pieces 113 of these spindles, the slide always remains in the middle between the ends of the walls 56 and 62. The spindles 110 and 110a are rotated until the pawl 77 of the pasting device 38 engages in the correct groove 84, 86., 88 and 90; '

which corresponds to the box size that is housed in the magazine shall be; the adjustable wall 62 is thereby brought into the correct position for receiving the boxes and locked in this position.

The output opening 40 (Figures 1A and 10) of the magazine 32 is at the Subframe 52 screwed. The opening 40 consists of an approximately U-shaped main part 130, the lower horizontally lying Section 132 slightly above the level of the box-bearing surfaces 59 and 63 of the fixed wall 56 or the adjustable wall Wall 62 protrudes temporarily resisting the movement of the lower edge 48 of the foremost box of the magazine perform. Two arms 134 and 136 protrude upward from the main part 130 and point to and from the arms inwardly protruding pivot pins 138.

A U-shaped lifting device 140 consists of upwardly pointing Arms 142 and 144 with their upper ends firmly on the pegs 138 are set and have a rod 146 for stopping the boxes firmly attached to the lower ends of the arms is appropriate. The rod thus extends transversely between arms 134 and 136 which spring back and forth near their upper ends are formed into stop surfaces 148 and 150, which prevent the arms from pivoting in the counterclockwise direction (according to FIG. 10). The rod 146 contacts the top edge 152 of the foremost box to temporarily hold it in the magazine, until they are withdrawn from the magazine under the action of the suction head 42 will. The lifting device 140 is normally in its working position, as it is drawn in Figure 10, by two spring-loaded load balls 154 of conventional design, which are shown in

009083/0080

the arms 134 and 136 are housed and recessed in. the lifting device 140 lock into place. Should be a box 'Do not detach from the suction head 42 at the depositing station D and into the . Withdrawal position P is returned, it touches the box only the rod 146, whereby it overcomes the holding force of the locking balls 154 and allows the rod to pivot clockwise (according to Pig.10), thereby damaging the opening 40 or the Suction head 42 is avoided.

It has been shown that the boxes, especially the long ones Quärtschachteln, 'at times tend to be in the middle of the long side from the magazine opening 40, making it difficult to reliably open the boxes. About this bending to prevent a nose 155 Q-n is the lower slide 100 screwed that about 3 now (1/8 ") up over the top Edge of the rod 132 protrudes from the trigger opening.

The stop pin 45 for opening the box is on a bracket 156 attached to the arm 136 of the U-shaped opening main part 130 is attached. The free end of the pin 45 is placed so that there is a tab 158 (Fig.10) on the rear wall 46 of the box C can touch; the lobe stands outward over the front wall 44 of the box. After the box has been withdrawn from the magazine 32 by means of the suction head 42, it is touched tab 158 engages pin 45 and provides movement of the box back wall 46 at their lower lock resistance, whereby the The box is partially opened from this end.

It can be seen most clearly in Figures 10 and 14 to 21, that the bending plate 50 has a flat upper side 162 with a curved upper end 164. From the mounting tabs 166 downwards

0096837 008 0

go out above. The tabs can be swiveled on a cylindrical ' drischen auf) lock 168 attached, which is integral with the. upper end of a bracket 170 related to the subframe 52 is screwed. The axis of the cylindrical block is in a plane parallel to the plane of the face of the Discharge opening 40 is located. This axis is also inclined by about 5 ° downwards to the horizontal, so that the lower edge 48,. the box, after it is partially opened, is inclined at practically the same angle as the flat surface 162 of the clincher plate 50. One of the tabs 166 of the clincher plate 50 has a curved adjustment slot 172 (Figure 11) through which a cap screw 174 engages. The screw 174 is screwed into the bracket 170 and enables the plate '50 to be rotated about the axis of the cylindrical block 168 is pivoted so 'that the flat surface 162 of the plate 50 in its angular position relative to the plane of the Opening 40 can be adjusted.

Since the upper edge of the bending plate is against the horizontal by 5 ° is inclined, and as it is desired, both ends of the box

to bend to the same extent, the compensating rod 51 is screwed to the upper edge of the bending plate; the top edge 176 of this Compensating rod runs horizontally. If now the suction head 42 pulls the box over the upper end of the clincher plate 50 and the rod 51, the box is bent over its entire length.

The suction head 42 can move the box from the withdrawal position P in to guide the deposit position D, and during this time the Box erected and bent. As best seen in Figures 11, 12 and 13, the suction head 42 has a main part 182 from L-Forra, which is rotatably arranged on a shaft 184

009883/0080

net is. The shaft 184 is seated at one end of a crank arm 186, rotatably mounted on a shaft 188 Istv ¹ I90'des frame is fixed at one vertical part 34th The other end of the crank arm 186 is rotatably connected by a link 192 to a pin 194 which is eccentrically mounted on a cam 196 and projects outwardly from the flat side thereof; The cam is keyed on a shaft 198 and is continuously moved by drive means which are described in detail in a patent application by Vadas et al. are described; the crank arm 186 thus reciprocates about the shaft 188. ·. _;

A crank arm 200 is pivotally attached to "a shaft 202, which is attached to the vertical portion 190 of the frame 34 to to control the swivel movement »of the suction head. A roller 204 is journalled at one end of the crank arm 200 and is slidably received in a cam track 206 on the suction head 42. The other End of the crank arm 200 is pivotally connected to a link 20.S, and the other end of link 208 is pivotally connected with the crank arm 186. In this way, the crank arm is made out the position shown in Fig.11 into the position shown in Pig.12 pivoted, with the suction head at the same time in the clockwise direction about shaft 184 as is pivoted about shaft 188.

Figures 11 and 12 show that the suction head 42 is a bending bar -

0Ö9883 / OÖ80

As shown in Pig. 13, the suction head 42 has three suction cups 216 which are connected by lines 218 to a valve 220 (Figures 11 and 12. The valve 220 is in communication with a vacuum source so that there is normally negative pressure on the suction cups. When the suction head 4-2 is in the storage position D moves, touches and opens a bracket held by head 42. 222 / a valve plug 224, whereby the suction cups 216 with the outside air.

The details of suction cups 216 and valve 220 are shown in FIG of the Knight patent application and do not form part of the invention. Further details can be found in the above Patent application.

In operation of the box erector 30 according to the invention the operator first determines which size the boxes to be set up and then turn the button 76 (Figure 9) of the locking device 38 until the required Box size indication, for example "Quart", facing the M mark. Then the operator only turns the crank 112 (FIG. 3) in the correct direction until the pawl 77 is in the slot 84 (Fig. 7), thereby holding the wall 62 in a position which permits the processing of "quart" boxes.

Then the operator holds the with the help of the hook 102 (Fig.1) Slide 94 at the top of the magazine so that the magazine can be loaded with a stack of boxes without the slide 94 interfering. If the magazine 32 is full, the Slide 94 released, which is countered by gravity downwards

. 009863/0000

the boxes is moved so that it pushes the boxes towards the opening 40 'which the boxes. releasable in the Magazine 32 holds until it is gradually removed from the suction head 42 can be withdrawn through the opening 40.

After the suction head 42 gripped the box and out of the opening 40, touches the tab 158 (^ Figures 10 and 14 to 21) of the lower edge 48 of the bottom closure BC of the box the cylindrical stop pin 45 so that the box progressively from the bottom seal end to the end of the top seal is opened. If the walls of the box tend to stick to each other, the opening is from one end on the other hand in comparison to the simultaneous opening of both ends more effective because it creates greater box opening forces that part of the two walls in close proximity to the bottom seal which tend to stick together until the moment when the walls separate, while at the same time the Resistance to the movement of the box that cause it the box could become detached from the suction head 42, less remain.

This gradual opening of the box from the bottom closure end BO to the end of the rough upper closure TC leads to the fact that the lower ■ The edge of the box is sloping about 5 °. the further movement of a box therefore has the consequence that the the entire length of the inclined lower edge 48 is the inclined flat surface 162 of the bending plate and the opening gang continues, starting with the bottom closure BC, the opening cross-section is greater at each stage of the opening process

009883/0080

As the cross-section of the upper opening TC, until the box is completely open, and then, as indicated in Figures 20 and 21, the bending process also begins at the bottom end and is more pronounced there than at the top end, until just before the Box from the folding plate 50. Is the box from the. Clinching plate 50 "is subtracted, the ^v upper closure TC and a. Greater part of the box body over the upper edge 176 of the balance bar 51 moves the horizontal stands and, therefore, bends all parts of the box in the same degree. Then 42 supports the suction head the box into the deposit position D and releases it there before it returns to the position P to pull another box.

The above description shows that the fast working Box erecting device according to the invention is a very simple and easy-to-use device with which the magazine for processing boxes of different types Size can be adjusted and that a device is provided is, with which an adjustable wall on the magazine can be brought into a desired position by simply adjusting the box size in question. The facility also has funds on, with which the box progressing from one end to the other can be opened, thereby reducing those forces that through their action on the sehachtel these Try to lift off the suction head. There are also bending devices provided with which the box from one end to the other end progressively Umogeijiwlrd and the finally

the Schaohtel only take off when both ends are equal are bent.
