Description

TECHNICAL FIELD

This application relates generally to case formers and, more specifically, to a case forming machine and system that facilitates formation and filling of cases of different sizes on an as needed basis.

BACKGROUND

In the packaging industry, products are packed by different type of case formers and case sealers before they are shipped to the consumers. One common type of case former and case sealer is semi-automatic case former and case sealer. This type of case former and sealer needs an operator to unfold the case blanks, use the handle to adjust the conveyors so as to match the case size and put the case between the conveyors to fold the bottom of the case. Similarly, the semi-automatic case sealer also needs an operator to use 2 handles to adjust conveyors to match the case size in order to grip the case sides by the conveyors firmly and another adjustment of the top tape applicator by handle is needed to allow the top tape applicator to touch the top flaps of the case. After the two adjustments, the semi-automatic case sealer is ready to apply adhesive tapes on top and bottom of the case. When different sizes of cases are used, then the operator has to repeat the above-mentioned adjustments again. The problems of this type of semi-automatic case former and case sealer are numerous. Firstly, many adjustments are needed to form different type of cases, which is time consuming. Secondly, the adjustments are carried out by the operator, in other words, the operator may have the chance to adjust it too tight or too loose and finally affect the result of case forming and sealing. Thirdly, if the user wants to avoid adjustment problems, more semi-automatic case formers and case sealers may be needed in order to handle many different sizes of cases, adding undesired cost.
Another type of case former and case sealer is the fully automatic case former and case sealer. This type of machine, to some extent, solve the problem of reliance on the operator to stop the machine to do the adjustments. The fully automatic case former and case sealer uses many sensors to detect and measure the width and height of the cases when they enter the machine.
The problems of this type of fully automatic case former and case sealer are that, first of all, because various sensors are used to detect the case size, it takes time to transmit the information back to the PLC and then get the instruction to adjust the conveyors and top tape applicator. Secondly, the accuracy of sensors may be affected by dust, mis-mounting of the sensors. Thirdly, sensors are more expensive and it makes the price of the fully automatic case former and case sealer higher than the semi-automatic case former and case sealer.
It would be desirable to provide a machine and system that is more readily adaptable to the need to form different size cases in an undefined sequence.

SUMMARY

One objective is to provide a single semi-automatic random case forming, case holding and sealing machine to complete the adjustment of random cases by one single adjustment process without the intervention of the operator manually moving components or using sensors that directly evaluate case size.

A case sealing section is axially downstream of the case holding and forming section, the case sealing section including: a bottom taper, an upper taper, the upper taper movable vertically to adapt to different case widths, and a pair of spaced apart conveyors for moving cases past the bottom taper and the upper taper for taping, wherein the spaced apart conveyors are movable laterally to adapt to different case widths. An adjustment system includes a memory storing a plurality of machine set ups, wherein each machine set up includes data corresponding to (i) lateral positions for the spaced apart walls, the spaced apart bottom major flap kickers and the spaced apart conveyors, (ii) axial position for the bottom minor flap kicker and (iii) vertical position for the upper taper.
In another aspect, a method is provided of forming, loading and taping a case using a semi-automated case handling machine that includes a plurality of components that are position adjustable based upon case size to be formed, loaded and taped. The method involves: scanning a code associated with a pick tray holding one or more items to be loaded into a case; and automatically moving the plurality of components to respective positions corresponding to a case size associated with the scanned code, in preparation for forming, loading and taping the case.
In a further aspect, a method is provided of forming, loading and taping a case using a semi-automated case handling machine that includes a plurality of components that are position adjustable based upon case size to be formed, loaded and taped. The method involves: inputting a case size code to a controller of the machine; and the controller automatically effecting movement of the plurality of components to respective positions corresponding to a case size associated with the case size code, in preparation for forming, loading and taping the case.

DETAILED DESCRIPTION

Referring to FIGS. 1-10, a perspective view of the semi-automatic case forming, case holding and sealing machine 1 is shown. The semi-automatic case forming, case holding and sealing machine 1 includes case forming device 2, case holding 4 and case sealing device 3. At the front part of the case forming device 2, a barcode reader holder 21 is mounted on the middle of the horizontal hollow rectangular bar 22. Inside the horizontal hollow rectangular bar 22, a horizontal shaft 221 is mounted. The horizontal shaft 221 is used to connect with the two inward or outward conveyors 25 and let the inward or outward conveyors 25 to move along the horizontal shaft 221 smoothly. At the bottom of the horizontal hollow rectangular bar 22, a front supporting leg with wheel 23 is mounted. At the two sides of the horizontal hollow rectangular bar 22, two inward or outward conveyors 25 are mounted. On the two inward or outward conveyors 25, two inward or outward conveyors covers 24 are installed to cover the inward or outward conveyors 25. Below the two inward or outward conveyors 25, two long kicker bars 41 are mounted, and on each of the two long kicker bars 41, there is a set of kickers 42 to kick the bottom major flaps to close and maintain a closed condition. At the middle of the front supporting leg with wheel 23, a rectangular bar 27 is mounted. Inside the rectangular bar 27, a long shaft 28 connected with the forward and backward motor 29 is mounted. On the long shaft 28, a rectangular block with 4 wheels 293 is mounted. This long shaft 28 is connected with a square hollow metal device 291. The rectangular block with 4 wheels 293 is mounted on the square hollow metal device 291. The square hollow metal device 291 is bigger than the rectangular bar 27 and is mounted at the outside of the rectangular bar 27. On the top side of the square hollow metal device 291, a bottom minor flap kicker 292 is mounted.
The case forming device 2 is connected with the case sealing device 3 by two connection flat plates 5. One end of each of the two connection flat plates 5 is mounted on the top side of a respective one of the inward or outward conveyors covers 24 and the other end are mounted on the top side of one of the two parallel conveyors 31. The two parallel conveyors 31 are positioned on the supporting frame 34 and the supporting frame 34 is mounted on the four supporting legs with wheels 32. At the front end and back end of the two parallel conveyors 31, two long shafts 33 are connected with the parallel conveyors 31. On each of the long shaft 33, there are two connection blocks, the connection blocks 332 are used to mount the two inward or outward conveyors 25, and the connection blocks 333 are used to mount the parallel conveyors 31. These connection blocks 332, 333 can move along the long shafts 33. Through the work of the two connection flat plates 5 and the connection blocks 332, 333 mounted on the two long shafts 33, they can cause the inward and outward conveyors 25 and the parallel conveyors 31 to move along the two long shafts 33 and the horizontal shaft 221 at the same time and accomplish the task of adjusting inward and outward conveyors 25 and the parallel conveyors 31 to grasp the case sides firmly.
At the middle of the supporting frame 34, a side motor 35 is mounted. The side motor 35 is connected with a rectangular plate 352 and the big sprocket 353 is located on the top of the side motor 35. At the two sides of the front end of the rectangular plate 352, two sprockets 354 are mounted. The big sprocket 353 is directly controlled by the side motor 35 and are linked with the side motor belt 351. In addition, the side motor belt 351 is also connected with two sprockets 354. A cover 355 covers the big sprocket 353. The action of the side motor 35 will drive the big sprocket and the side motor belt 351. The side motor belt 351 also links with the two long shafts 33 by the sprockets 331 mounted on the top of the long shafts 33. The two long shafts 33 are connected with the two parallel conveyors 31 and the inward and outward conveyors 25. As a result, the movement of the side motor 35 controls the inward or outward movement of both the inward or outward conveyors 25 and the parallel conveyors 31 at the same time. Between the two parallel conveyors 31, a bottom tape applicator 7 is installed. At the two sides of the supporting frame 34, two vertical hollow bars 36 are mounted. Inside the two vertical hollow bars 36, two vertical shafts 361 are mounted and the two vertical shafts 361 are linked with a top tape applicator supporting bar 61. At both ends of the top tape applicator supporting bar 61, there are two plates 611. On the plates 611, each carry 4 wheels 612. These wheels 612 help the top tape applicator supporting bar 61 move along the two vertical shafts 361 upward or downward smoothly. At the center of the top tape applicator supporting bar 61, a top tape applicator 6 is mounted. A top bar 362 is connected on the two ends of the vertical hollow bars 36. At the bottom side of the top bar 362, the top motor 37 is mounted to drive the top motor belt 371 and the top motor belt 371 is connected with the two vertical shafts 361 by the sprocket 363. The top motor 37 is like the side motor 35. The top motor 37 is connected with a rectangular plate 372 and the big sprocket 373 on the top of the top motor 37. At the two sides of the front end of the rectangular plate 372, two sprockets 374 are mounted. The big sprocket 373 directly link with the top motor 37 by the top motor belt 371. The top motor belt 371 is also connected with the two sprockets 374. A cover 375 covers the big sprocket 373. On the top side of the top bar 362, a HMI arm 81 is mounted. The HMI arm 81 is movable, so that the HMI 8 mounted on HMI arm 81 can move based on the need of the operator.
When in work, an operator will use the digital code reader to scan the digital code attached on a pick tray, then the PLC will, based on the pre-stored information for the scanned digital code, instruct the forward and backward motor 29, the side motor 35 and the top motor 37 to adjust the semi-automatic case forming case holding and sealing machine and, in some embodiments, the control of the machine will also output an indication (e.g., visual) to communicate to the operator the case size needed for the items in the pick tray. In detail, the forward and backward motor 29, which is connected with the long shaft 28, will move. This forward and backward motor 29 with long shaft 28 is connected with a square hollow metal device 291. On the top side of the square hollow metal device 291, a bottom minor flap kicker 292 is mounted. The movement of the forward and backward motor 29 causes the movement of square hollow metal device 291 along the long shaft 28 forward or backward. Inside the square hollow metal device 291, a rectangular block with 4 wheels 293 is mounted, which can make the square hollow metal device 291 move smoothly forward or backward. The bottom minor flap kicker 292, mounted on the square hollow metal device 291, is also moved and achieves the adjustment of the case size. At the same time, the side motor 35 also drives the side motor belt 351 to work. The two sides of the side motor belt 351 are linked with the sprockets 331 which are located on the two long shafts 33 and the connection blocks 332, 333 mounted on the two long shafts 33 are also linked with the two inward or outward conveyors 25 and the two parallel conveyors 31. The two parallel conveyors 31 of the case sealing device 3 are connected with the two inward or outward conveyors covers 24 of the case forming device 2 by two connection flat plates 5. Then, the movement of the side motor 35 will finally cause the two inward or outward conveyors 25 and the two parallel conveyors 31 to move inward or outward simultaneously. At the same time, the top motor 37 will drive the top motor belt 371 and the top motor belt 371 is connected with the two sprockets 363 located on the top of the two vertical shafts 361. The two vertical shafts 361 are also connected with the top tape applicator supporting bar 61. As a result, when the two vertical shafts 361 move upward or downward controlled by the top motor 37, the top tape applicator supporting bar 61 also moves upward or downward. As the forward and backward motor 29, the side motor 35 and the top motor 37 receive instructions and work at the same time to adjust the square hollow metal device 291, the inward or backward conveyors 25 and parallel conveyors 31 and the top tape applicator supporting bar 61. The case size adjustment is done within a minute and a case space matched with the adjustment is ready to put the folded case blank in.

Thus, a semi-automatic case forming, holding and sealing machine includes three devices, the first one is the case forming device, the second one is the case holding device and the third one is the case sealing device. Through the cooperation of the three devices, a single semi-automatic random case forming, holding and sealing machine can carry out the work of forming, holding and sealing random size cases without multiple adjustments of both the semi-automatic case former and case sealer by the operator. All the operator needs to do is to put the right case into the case forming device to grasp the side walls of the case, then the case holding device will fold the bottom major flaps, hold the bottom flaps folded case for the operator to fill the bottom flaps folded case with goods. After filling the case, the operator will push the case into the case sealing device to seal both the top and bottom flaps of the case. In one embodiment, semi-automatic case forming, holding and sealing machine has a digital code reader holder mounted at the front of the machine to hold a digital code reader. This digital code reader is one embodiment. The data of random case sizes are pre-entered into the PLC of the semi-automatic case forming and sealing machine (e.g., in memory) before the machine starts to work. Once the digital code reader reads the code (e.g., the scannable code on one of the pick trays T traveling along a tray conveyance path Cl alongside the machine opposite the operator side of the machine), it will trigger the e-commerce software to provide the case size to the PLC and the appropriate light bulb (or other annunciator) A, which may be associated with each case rack CR proximate the operator side of the machine, will flash to indicate which case size is needed (where the different case racks hold different case sizes). The machine will adjust the case forming, holding and sealing devices to match with the selected case size before the machine starts to work.
In embodiments, no digital code reader is needed. All applicable case sizes are pre-entered into the PLC with the HMI and each applicable case size is assigned a reference number in the HMI. Once the operator decides which case size will be used, the operator just needs to press the case size number on the HMI then the semi-automatic case forming, holding and sealing machine will adjust the machine to match with the case size chosen and the operator only needs to pick the correct case and put it in the machine to fold and hold the bottom flaps closed for goods to fill in.
The case forming device includes a case side flaps adjustment device, a bottom flaps adjustment device, a case holding device and a PLC mounted at the bottom of the case forming device. At the bottom of the semi-automatic case forming and sealing machine, a forward or backward motor is connected with a bottom minor flap kicker by a square metal hollow device. The square metal hollow device is mounted on the outside of the rectangular bar. Based on case size information, the forward or backward motor will move the bottom minor flap kicker to move forward or backward to adjust the length of the case size and the holding device includes a two long kicker bars and on the two long kicker bars, two sets of kickers will bend the bottom major flaps and the two sets of kickers will kick the bottom major flaps to close. The case holding device is mounted in the inward or outward conveyors, to close the bottom flaps of different cases and maintain the closed bottom flaps of the case for operator to fill in goods before sending the case to the sealing device to seal the bottom and top of the case. The two inward or outward conveyors are mounted in the two inward or outward conveyor covers. At the front end of the case forming device of the semi-automatic case forming and sealing machine, a case sealing device is connected with the case forming device by two connection flat plates and formed a single semi-automatic random case forming and sealing machine. These two connection flat plates are mounted on the top of the two inward and backward conveyors covers of the case forming device and two parallel conveyors of the case sealing device separately. It makes the two set of conveyors move simultaneously. The movement of the two sets of conveyors is controlled by a side motor mounted at the side of the case sealing device. The case sealing device includes a set of parallel conveyors to grip the two sides of the case, a side motor to control the inward and outward movement of the parallel conveyors and the inward or outward conveyors and one top tape applicator, one bottom tape applicator to seal the top and bottom flaps of the case, one top motor and one HMI.
