Description

The invention relates to an automatic stapler for cardboard boxes.

U.S. Patent 3,126,685 discloses a machine for simultaneous closing of the lid and bottom of Cardboard boxes known. This machine automatically centralizes the carton in the machine and brings it at the same time With this movement, two upper and lower stapling heads in a position in which they are above and below end sections of the box are opposite. The heads are made to automatically staple up and down shoot down into the box. After this first zeroing in of the four stapling heads, the upper pair of Heads raised, all four heads are shifted inward individually over equal distances, and the top one Pair of heads is lowered and in contact with the card

sound brought. Then all four heads are operated again so that staples are shot into the box. Of the The machine's work cycle ends with the retraction of the carton centering device and the stapling heads in their home positions so that the carton is released for removal from the machine.

A considerable proportion of the time required for a work cycle is used in this known machine for centralizing the box in the machine, for moving the upper pair of stapling heads to at the bottom and at the top in each of the two stapling processes of these heads, and finally that is possible. Pulling away the carton centering device and the stapling heads return to their respective starting positions.

The invention has for its object to shorten the total time of the Ksrtonschüeß cycle of the machine and thus to increase the production capacity.

The object on which the invention is based is achieved by a device for conveying a cardboard box along a transport path forming a guide path to a work station in the machine, through stapling head devices with a face plate, which is intended to be placed on one side of the cardboard box and above the transport track is arranged in the work station and is used to hold staples spaced apart and in a predetermined pattern one side of the box parallel to the guide path

drive, through a device eur holder of the stapling head direction in an essentially stationary position relative to the plane of the cardboard side, by means of a drive unit, which guides the box side into sliding contact with the faceplate, and through a staple control device, which causes the staple head assembly to feed staples into to drive the pattern into the cardboard side from the fixed position.

An essential feature that contributes to shortening the work cycle relates to the compulsory initiation of the Cartons into a work station in the stapler along a guided path so that all that is required is " to bring the box into the correct position for the first stapling cycle, the powered transport device stop when the box arrives at the workstation. According to the present invention are upper and lower Pairs of stapling heads firmly attached to a horizontally hinged cover Frame attached so that these stapling heads are already in a correct position for driving a pair of yon Staples down into the top of the box and another pair of staples near the top Bottom of the carton are arranged when the carton arrives at the workstation. In addition, the Arrival of the box at the workstation and stopping the transport device for the purpose of stopping the feeding movement of the carton when the carton is

909850/0750 ~ * ~

located in this workstation, causes a triggering of all four stapling heads so that they are caused immediately Shoot staples into the top and bottom of the box in the manner indicated previously.

The frame for holding the stapling heads has two positions, a primary stapling position and a secondary Stapling. It also has a separate drive device that, when properly bumped, the Frame moves from one position to the other. The full duty cycle for everyone in the machine entered cardboard consists of two separate stapling cycles ·, with the frame in one of the Positions and in the second cycle in the other of the positions. The first of these stapling cycles is automatic by stopping the transport device and by stopping the carton in the machine's workstation and the completion of this stapling cycle pushes the means for moving the frame into its other Position on. The arrival of the frame in this other position causes a triggering of the stapling mechanism, so that the second of the stapling cycles required by the duty cycle on that particular carton is running. To the The second of the stapling cycles follows that the frame on which the stapling heads are mounted in the same Position in which he is during the second stapling

-5- 909850 / 07S0

cycle and the input or feed mechanism is triggered by the completion of this second stapling cycle, so that it brings another box to the work station advances and thereby pushes the cardboard out of this, which has just before a complete work cycle has been subjected to the machine.

By the arrival of a new boxes in the work station, a new duty cycle is started, the exactly the same as that described above, with the initial m would take, that it begins with an initial stapling cycle in which the support frame for the stitching heads in the Position is in which the second stapling cycle of the previous last work cycle has expired. Completion of this initial stapling cycle triggers the frame shifting device to return the Rabaen to its other position. The arrival of the frame in this position nudges the stapling heads and causes their second stapling cycle of the one previously described

Work cycle to go through. The frame then remains in ^ his last-mentioned position, while the carton entry device, initiated the termination of the second stapling cycle of the previous work cycle to work has been, pushes another box into the workstation of the machine and thus pushes the box out, the one just before the stapling cycles of the work cycle that has just ended has been subjected.

909850/0750 ~ ⁶ ~

The stapling heads are attached to their holding frame with a ' adjustable fasteners that allow the locations of the staples to be varied a carton that has been directed into the workstation. The input device for the box can also be adjusted so that the exact position of the workstation in the machine can be varied in which the box is stopped during the stapling cycles of the machine cycle for stapling the box. To this Thus, the input device can be adapted to boxes of different sizes. The lower pair of in the Machine provided stapling heads is attached to the movable frame carrying these heads so that the upper surfaces of these heads are immediately below the bottom of the carton when it is in the workstation is located, and the upper pair of staple heads is located substantially directly above the lower pair of heads, with the lower surfaces immediately above the box. The device on the frame for holding the upper stapling head is vertically adjustable, so that an adaptation to boxes of different heights is possible.

The input device for cardboard boxes has horizontally adjustable lateral guides. The setting is made so that an accurate guide path for boxes of different widths is formed. The machine can be used for

—7—

90 9 850/0750

a certain setting of the guides only remove cardboard boxes of a "certain width. The input device for cardboard boxes also has an overhead, vertically adjustable shoe which is arranged so that he the guides the top tabs of each carton down as it is advanced into the working position so that these tabs get under the top stapling heads of the machine.

The punctures according to the invention allow one independent sequence of each work cycle from start to finish. It is only necessary, one continuously Enter a series of cardboard boxes to cause this cycle of operation to repeat itself continuously. the The feeding speed must match the capacity of the masobine be coordinated to automatically close the boxes. The presence of a box on the input conveyor of the machine at the moment in which a work cycle when a carton previously entered into the stapler is finished, it causes an automatic ejection of the last-mentioned cardboard box and a pushing and initiation of a further work cycle by introduction of the new box in the first workstation.

In addition to the advantageous properties of the invention explained above, the electronic control means for the input conveyor belt for cardboard boxes very easy to adjust to the point in the stapling device

-8- 9 09850/0750

vary at which the box stopped on its way there previously referred to as the workstation. Because of this, the vertical transverse plane in the Machine in which staples from all staple heads - during the first stapling cycle or during the first and second Staple cycle shot in, considerably closer to the front end (or side) of the carton than the rear End (or side) of the box.

The electronic input control can also be set so that the automatic Operation of the stapling heads on a single box during pauses between successive yor movements of the the latter can be inserted through the input conveyor belt, in pauses in which the carton is in each case in a series of successively advanced work stations stopped in the stapler of the machine will.

This possibility allows the inventive Setup is simple and with a few simple settings and very quickly and precisely during each work cycle to adapt to an automatic mode of operation, to both three or four rows of staples in each row in the top as well as in the bottom of the box. These rows are parallel and distributed in ■ the direction in which the box goes through the stapler

-9- 9098E0 / 0750

is transported, namely they lie on the surfaces and Unterfläcben of the cardboard.

The usefulness of the device according to the invention also extends to performing relatively simple stapling operations quickly and accurately. For example can by simply flipping a hand switch for one the device that moves the stapling heads horizontally so that the machine, together with suitable settings of the infeed conveyor belt, it is switched to automatic shooting in of two Staples near each end of a cardboard box on both the top and bottom on opposite sides the middle longitudinal line (where the side flaps meet), while this box lengthways (lengthways) is guided through the machine, with short pauses for the Stapling cycles.

The invention is to be explained in more detail with the aid of the drawing.

In the center of the conveyor belt 33, a tact switch 65 is arranged in the gap, its functional significance in! ig. 7 is clarified. This switch is arranged relative to the conveyor belt 33 that it through a box C is depressed when it is placed on the conveyor belt 33 and runs over the switch.

The following is a particular reference to the Pig. 8, 9 and 10 are referred to. A plate 70 is attached to the outer surface one of the metal side walls 31 of the Input device 26 attached from cardboard. This plate 70 has a bearing 71 and a pair of pins 72 which extend horizontally from the plate outwards to below the bearing. A shaft 73 is mounted in the bearing, on the inner end of a sprocket 74 is attached, which is driven by an endless chain 75, which to the sprocket and around sprocket 60 (see Fig. 4) is guided. On the part of the shaft that extends outward 73 a disk 76 with a hub 77 is attached, on which a cam disk 78 is free for switch actuation is rotatably held. The disc 78 is provided with a pair of curved slots 79 in the edge area. the Disk 78 also has holes 80 at diametrically opposite locations and relatively close to hub 77.

On the disk 78 are on in the circumferential direction of the

Holes 80 distant points extending outward

-15- 909850/0750

Pins 85 attached. On the disc 76 are at diametrically opposite places pins 86 attached to the siota horizontally through the holes 80 extend. The outer ones The ends of the pins 85 and 86 are provided with grooves to hold eyelets, the sieve at the ends of tension springs 87 are looped around the ends of these pins so that rotation of disk 76 is caused by rotation of the shaft 73 is transmitted resiliently via helical springs 87 to the cam disk for switch control. This rotation of the Shaft 73 takes place in the direction of an arrow 88.

The cam disk 78 is provided with pins 89 and 90 for switch actuation, the first of which is a short pin and the latter is called a long pencil. These Pins are arranged in one of the curved slots 79 of the cam disk 78, as is clear in detail from FIG. 10, which illustrates the properties that sioh generally result from the pins 89 and 90, as well as peculiarities which are associated with the long pin 90. As can be seen from Fig. 10, each of these pins cylindrical stop ends 91 which have a diameter '(| are greater than the radial width of one of the sole seats 79. In addition, each of the pins has a threaded stem 92 coaxial with the soleplate end and a Has outer diameter that fits into the slot and is long enough to fit one or more sleeves 93 and nuts
