Description

[Detailed description of the invention] This invention relates to the conveyance of various materials, more specifically to the automatic conveyance of sheet materials. It is.

It is often necessary to transport materials from one location to another. for example, Sheets of corrugated or cardboard - often stacked - are used as holders. It is transported from the pick-up location, then stacked in a hopper, and the rare items are placed on the sheet. It is fed to a printing press that prints the desired characters.

Stacks are manually transported from the receiving location and then stacked into the hopper manually. However, it is desirable to automate the refinement. For that purpose Many methods have been devised for this purpose. A typical example is that in January 1969, J.A. , U.S. Patent No. 4,322,969, issued to Miller et al., February 1972. U.S. Patent No. 3,643,939 issued to H.A. Nasunozum et al.; , U.S. Patent No. 4 issued to Karl R. Mulsky on October 10, 1978. , No. 119, 219.

The above-mentioned conveying systems, as well as other prior art conveying systems, have many drawbacks. . Broadly speaking, they are characterized by significant complexity and insufficient reliability. . In addition, any mechanical or If there is another failure, do not remove the receiver. 1-The device is interposed between the loading section and the sending section If there is, continued use of the delivery v attachment is prevented.

In the case of U.S. Pat. No. 3,422,963, the stack to be conveyed to the delivery station is Upset on a slope. On that slope, the weight of the sheets added to each other is This may interfere with the desired delivery supply. Furthermore, the upset is This is done by tilting the slats to form a pack rest. , and enough to reduce the weight of the top sheet added to the bottom sheet of the stack. must be lowered to the minute. As a result, along the slats, the upper sheet Inappropriate gravitational forces act for proper supply. Moreover, this system , the conveyor has a larger inclination angle than the inclined conveyor that feeds the sheets into the delivery section. Use an exit conveyor. This change in angle of inclination is a major factor in the proper feeding of the sheet. This is creating major obstacles.

The collision of approaching sheets causes a very large impact on the sheet on the slope. This creates a lot of pressure, which can cause it to get stuck.

In the case of U.S. Pat. No. 3,643,939, a fully loaded Conveyors that require constant circulation must be used. the The result is a system that is extremely complex electrically and mechanically.

In the case of U.S. Pat. No. 4,119,219, the top edge of the stack of sheets is continuous The sheet is then fed into rotating rollers that lift the edges and then feed the bundle of sheets. A lip is formed by a second roller in order to The edges cannot be lifted continuously or if the two rollers are not working properly, a feed jam may occur. I sometimes cheat.

A conveying system that does not disrupt the consistent flow of material even during temporary outages is Pulp U.S. Pat. No. 3,982,750, issued July 28, 976, and No. 4,008,890, issued February 22, 1977. Ru. However, they require considerably more space.

detailed description Referring to the drawings, a conveyance system according to the invention is shown in FIG.

The system 10 includes a stack supply conveyor 100, a stack lift 200, , Main Frame 300. Separator mechanism 400, upset instruction mechanism 50 0 and a feed base 600. The operation of the conveying system 10 is separate. control panel 700. Some switches in the main frame 300 Additional control is provided by chip 310.

Typically, this conveyor 10 carries a stack of sheets as shown above the supply conveyor 100. It operates on a stacked material such as stacked body S. Stack S as appropriate. are conveyed to the supply conveyor 100 by means of. For example, as partially shown in Figure 1. The loading drive is placed on an auxiliary roller conveyor such as unit 90. carried from the rack.

The stack S is properly positioned relative to the backstop 310 of the frame 3000. When lifted, the stack is lifted by lift arms 201-1 and 2 of lift 200. 01-2 lifts vertically along the backstop 301. stack The separator 400 separates a predetermined bundle of sheets 9 from the stack S. Take one piece and move it into the passageway B indicated by the dotted line in the main frame 300. Lift it up to a position where you can move it forward. A bundle from stack S The mechanism for separating the sheets and advancing them along path B is as described later. It is.

- When the bundle of sheets passes the knee part K of the passage P, the slide 50 of the indicating mechanism 500 1, between side panels 502-1 and 502-2, due to gravity. Ru. In Figure IK, only the side panel 502-1 is visible, but the hydraulic control cylinder the other side panel that moves together with the first side panel 502-i by the It will be seen that there is 502-2. Figure 1 shows multiple hydraulic cylinders. Of these, only cylinder 503-1 is shown.

When the stack is lifted by lift 200, the sheets face each other. They are facing each other. A bundle of objects moving along the internal passage P of the main frame 300 The sheets have their faces facing each other and their lower surfaces are in contact with the passage P. Contains sheets. However, when the -bundle of sheets passes through the knee area of path P, the lowest It is not separated along the bottom surface of the sheet, but also along the edge of each sheet. It will be 1r. At this point the edge of the sheet is along the feed platform 600 and the edge of the sheet is The tush arm advances the bundle of sheets along the feed platform 600. Feed stand 6 It is desirable that there is a hopper at the end of 00, and the sheet is being fed into a printing press that is continuous and provides the appropriate pattern on the face of each sheet become.

System 10 engages a wheel 11 supported on a suitable track 10. figure 1, only the wheel 11-1 is located in the central groove of the track 12-1. I can see. Because system 10 is roller-mounted, if system 10 requires repairs, If a failure occurs, the hopper located at the end of the feed platform 600 Can be moved to allow manual loading into other cradle.

The various functions of the conveying system 10 are performed by means of parts including various control nozzles 701-713. control of the channel 700. Thereby, the lift 200 is made manual or is subject to automatic operation. Also, the push-pull between guide plates 502-1 and 502-2 is The shears are controlled and the guide plates can be controlled as a whole or individually. control, etc. Further, the control switches 311 to 315 are It is located near the backstop 301 on the side panel of the horn 7 frame. . This control switch controls the conveyor 100 to operate it manually or automatically. The components of the backstop 301 are controlled so that Additionally, the system 10 includes a scrap removal conveyor 80 , and this conveyor 80 carries the stacks on top of the supply conveyor 100. Place the irregular sheets from Nemono S onto the bottom edge of the backstop and onto the scrap removal conveyor. The opening between the upper surfaces of the arm 80 is allowed to pass through. individual scraps The manner in which the sheets enter the scrap removal conveyor is as described below. .

An overview of the various components of the conveyance system 10 is shown in FIG. Minutes from Figure 2 As shown, the mainframe 300 It has girders to support the entire structure on p-211-1 to p-11-4.

The rollers are located in tracks 12-1 and 12-2 of the rail.

As can be further seen from FIG. Tag7-4201-. 1 and 201-2. Arm 201-1 and and 201-2 rise vertically between side girders 311-1 and 311-2. is fixed to a transverse member 202, which can be Members 311-1 and 31 The positioning of member 202 within 1-2 is conventional.

In the embodiment of FIG. 2, the lift 200 includes a supply con- It has additional arms 201-3 and 201-4 located therebetween. This arrangement The equipment allows the lifting and handling of stacks of varying longitudinal lengths. It is.

The supply conveyor 100 has three belts 101-1 to 101-3. Ru. One end of the belt is wrapped around a series of pulleys connected to a common shaft 102. It is. The other end of the belt is connected to the fork arms 201-3 and 201-4. It is wrapped around a pulley that is supported so that it can remain in place.

The backstop 301 provides access to the scrap removal container 80. It is lifted beyond the line of support arm 202. In the latter case, the stacks are conveyed When positioned above 100, the irregular sheet enters the scrap removal container. operates at times.

When the stack is brought under the lift 200 by the conveyor 100, the backs It collides with the top 301 and is lifted.

There is a movable part 302 in the center of the backstop.

The stack is placed above the edge of the fixed backstop 301 with the sensor ( (not shown) to a controlled position. That's how much stuff I've piled up Once it reaches the upper edge of the fixed backstop 301, It is located above the front stop 303 and in contact with the front stop 303. front stop 3 03, the sheet bundles moving along the conveyor 304 are aligned and there are no jams. It is used to stay stationary with respect to the inclination indicating member 501 so as not to cause It will be done.

Transfer to conveyor 304 is a separator with stripping fingers 402 400. In FIG. 2, the separator 400 is a site 9 plate. Suspended from frame 300 by side plate 403-2 only shown. It has been lowered. For the stripping finger 402 and the seventh/grater plaid 401. The support girder extends between a plurality of side plates including side plate 403-2. It is growing. Specifically, the supports and support beams 404 and 405 are seven rotor plays. ) 401 and a hydraulic cylinder 40 for actuating the stripping finger 402 It is equipped with 4h and 405h.

The stripping finger 402 is actuated to remove a stack of sheets from the lifted stack. When the sheet is separated and moved towards conveyor 304, the sheet Passing the front pulley of 04, the inclined support member of the upset support mechanism 500 50113 actuated by - aligning and resting the sheets of the stack against the inclined support member 501; let - The sheets of the stack are then upset on the feed platform 600. Upset is be carried out in the same or opposite arrangement as on the supply conveyor. It will be done. For that purpose, the upset arm shown in the example in Figure 3 is exist. - When the sheets of the bundle are positioned on the feed platform 600, the bushing arm 6 01-1 and 601-2, output rollers 602-1 and 6 When it reaches 02-2, it is moved along the feed platform. One in this place The sheets in the stack are transferred to the next unit, such as a feeder holanau to a printing press. It will be done. As in the embodiment shown in FIG. 03-2, and the sheet bundle has a lateral length that exceeds the distance between the two parts. It is desirable to have In the case of a narrow width sheet, two parts 603-1 and and 603-2.

In addition, the bushing arms 601-1 and 601-2 are equipped with a seam as described later. It is pushed down below the point.

The above structure and arrangement is further explained by FIG. In Figure 3, the stacking The stacked goods lift 200 moves upward along the side girder 311. There is. To that end, the lift 200 includes a and rollers 205 and 20 that contact the opposite side of the sight guarder 311-1. 6 and has a roller-engaging carriage 204 formed by 6. Sent ( When a stack of items is placed on the conveyor 100, the stack is placed on a fixed backstack. It is advanced until it contacts the top 301. As the pile is lifted and contacts the movable backstop 302 actuated by the cylinder to separate the 3. Accomplish positioning of the stack prior to actuation of the motor 400. on conveyor 301 Final positioning of the stack against the floor is done using hydraulic cylinder 303H. This is done by actuation of actuator stop 303. On the right side plate 403-2 The provided separator is sufficiently lifted by the hydraulic cylinder 401H. The stripping finger 40 is actuated by the separate plate 401 that is 2 is operated by a hydraulic cylinder 402H. Seno(lator 400 is a liquid It is pivotably adjustable by actuation of the pressure cylinder 401. As shown in Figure 3 , the latter operation is performed by the side play) 403-2 and the opposite support (not shown). The id plate is caused to move in an arc along the axis point 400P.

The operation of the separator is to take a bundle of sheets of a predetermined height from the stack and It is advanced toward the conveyor 304. In Figure 3, it is separated from the stack S. The bundle of sheets B1 that has been It is shown moving on the conveyor to the position. In the specific example shown in Figure 3, , the inclined support member 501 is connected to the descending conveyor 501. d, and this con is ah , operated by a hydraulic cylinder 501h. Purpose of descending conveyor 501d is the impact sound that occurs when the bundle B1 of the sea river passes the knee part K of the conveyor. The goal is to reduce the Next, the hydraulic cylinder 501h is lowered and the conveyor Lower the arm 501d to the same level as the inclined support member 501 5 and prepare for the next upset.

In the embodiment of FIG. 3, the upset is carried out by a hydraulic cylinder, not shown. This is performed using an arm 505 that reciprocates at the same height as the surface of the feed table 600.

Following the upset, the side panel 502 is activated. side panel 502 -1 is applied to the surface of the inclined support member 501 by the hydraulic cylinder 503-1. It is able to move laterally. Sheet bundle B is then transferred to P4-1, When arm 505 moves forward, it will upset. As a result, the bundle of sheets B closes the position of P5 and becomes ready to be transferred from the feed stand to the receiving hopper.

In the example of FIG. 3, the forward movement of sheet bundle B from position P5 is caused by pusher -601. Unlike the case in FIG. 2, the pusher 60 in FIG. 1 does not go below the 6000 level of the feed table, so the tilt support must be set before feeding. The holding member 501 must be retracted.

The above operation of the embodiment of FIG. This is done using equipment such as the Fort Electric Sensor. Used in Figure 3 There are many types of sensors, each of which has a different quality, indicated by the various numbers in the table below.

17 System 10 may be operated manually or automatically.

Appropriate control can be achieved even manually by energizing various sensors. It will be done. In the case of automatic activation, a sensor signal is generated to perform a series of continuous actions. It will be done.

Controls for automatic operation of supply conveyor 100 and movable back stave 302 The circuit is shown in Figure 4A. Operation of system 10 generally involves a feed conveyor. Drive motor (not shown) for arm 100 or movable backstop 30 2 by actuation of various drive motors, such as similar motors (not shown) for , performed using an alternating current power source. In addition, as described later, the system are operated by various relays energized by the DC signal obtained by rectifying the It will be done.

For this reason, this system has two busbars. 1 tsubaki 9 The other one is for direct current. These busbars are With two additional busbars for each, for when flow control is performed automatically. It has been supplemented.

According to FIG. 4A, for feed conveyor 100 and movable backstop 302 The control circuit for this will be explained. Automatic control using the AC memory bus is performed using switch 7 in Figure 1. This is done by a stop switch corresponding to 02. The stop switch 702 When in the closed position, an alternating current signal is applied to the forward movement of the conveyor through a series of contacts. is sent to the motor coil 102M-1. Each contact communicates with a relay, Two parallel lines that are normally open and closed when the connecting relay is energized , the contacts are indicated. Conversely, if the connecting relay is energized with the closed contact, it will open. For contacts, parallel lines of contacts are joined by diagonal segments.

In the control branch for the supply conveyor 100, there are open and closed connections. The point is designated as KSD-A, while the normally open contact is designated as KPU. Ru. In either case, K indicates a contact point. In the code KSD-A, SD is shown in Figure 3. This means "detection of stacked objects" in block 24. The code [N is in this example shows that there are two stack detection relays designated as rAJ and rBJ. means. The following series of contacts in the control path, designated as KPU: (7) in Figure 3) until the hawk-lator 400 has pivoted to a sufficiently upward position. - Indicates that a kit is present. The next set of contacts, designated as KBO, are movable An open circuit exists until backstop 302 extends to the position shown in Figure 3. Indicates that it exists. Final in control branch for supply conyer The contact group is designated as KLD-A. This code is riff) 200 is "descending" , the rAJ relay is activated by the signal from the detector block mark 2 in Figure 3. - means that it is energized.

In the embodiment shown in FIG. Shunt switch 615 allows contact KBO to be bypassed. It is designed to be This is the position where backstop 302 is shown in FIG. Even if it is not fully extended, the stack can be fed at the operator's choice. This is what makes it possible.

In normal automatic operation, the feed is free of prior stacks on the conveyor. It is done in case. This means that the detector is not activated and the leading edge This occurs when the relay connected to the detector does not open contact KSD-A.

Furthermore, the SE and J rate axes must be sufficiently raised. In other words, The dynamic KPU must be open. This shows that the stacks of things being sent are This is to prevent it from getting caught on the lower part of the separator 400 of No. 3. Movable pad □Top 302 must be fully extended by closing contact KBO. do not have.

This allows the stack to be fed when it is higher than the fixed backstop line. This is to properly separate it from the backstop.

This effect can be achieved manually by the operator using switch 615. It can be done by Lower the lift while causing the closure of point KLD-A. I have to. The stack/object S of FIG. 1 is then transferred to the detector of block 24 of FIG. Activate 21 8D-A is opened at the contact point. Stacking is the next step in continuous automatic operation. sent to the desired location.

Before we talk about automatically lifting the sheet and stripping it from a stack of sheets, Contactor coil 3 for forward and backward movement of backstop motor (not shown) In conjunction with the control branch including 02C-1 and 302C-2, a movable battery This section explains automatic operation of the stop. After having contactor coil 302G-2 The branch for leaving work has relay contacts KGB (normally open) and KBR (normally closed). have. The stack approaches the movable backstop and is shown as block mark 4. Contact KGB, which activates when the detector position is reached, is connected to backstop 3. 02 until it reaches the position of the detector block mark 5, and then the contact K ER opens and becomes the [backstop retracted] position. backstop 302 The passageway for automatic advancement has an advancement contactor coil 302C-1, normally in the closed position. It includes contacts KBO, KGB, KCBL and KSD-A located at the same location. Contact K The first set of LD-A is normally open. Contacts KCB, KCBL and KSD-A is when there is a stack of objects approaching the backstop or when there is a stack detected. ” is closed except when the lift is sufficiently low. When D-A is activated, the stop will be fully advanced to the position shown in Figure 3. , At that position, the detector with block mark 3 is activated and the relay is communicating with contact KBO. energize and open the forward control branch.

This way, when the lift is down and not above the stacked lift, the The block stop 302 is fully extended and the block stop 302 is fully extended to activate the detector at block mark 4. It remains in the extended position until the stack is on the lift. Therefore, movable backs The top is designed to ensure that approaching tall stacks are properly removed from the fixed backstop. The height of the backstop is lower than the position of the movable backstop. It is programmed to avoid conflicts with subsequent lifting of stacks.

A control that automatically raises the lift to strip off the upper part of the stack. The rub branch is shown in FIG. Relay R-KRL, i.e. raise the level 7. The control in Figure 4B, including the relays for the contacts K, which are normally open, SD-A.

KS1i'U, KBOR and KBR, and 8 to 6 normally closed contacts. ．． K13. KSA4. KPCP, which contains 8KP, is therefore on the lift. As long as there is something stacked in the It operates and closes contact KSD-A, and the front stop 303 in Fig. 3 rises sufficiently. actuates the detector marked block 8, thereby closing the contact KSFU. Sara In addition, the stripping finger 402 must be fully retracted and the block The detector at mark 7 must be energized to close contact IPOR. lastly , the backstop 302 also prevents interference with rising stacks, as mentioned above. Must be sufficiently retracted to avoid. Contacts that are normally closed are Unless the system 10 is activated, that is, there is no detector 13 on the conveyor 304. The closed position is maintained as long as there is no sheet bundle in the position. The pile is , the position of the detector of the flock mark 9, which activates the contacts KPCP and KSKP open. ,3 In other words, it continues to rise until it reaches the stripping position. The lift is marked as a block. If the highest raised position of 21 is not reached, contact KLU opens and "lift-up" is activated. bring about.

Once the above conditions are met, relays R-KRL are connected to the hydraulic lift motor (not shown). ) actuates the contacts KRL of the second control branch, including the contactor coil KRLC for Ru. Other contacts for hydraulic lift motors include normally closed contact K. There is a BU and a normally open contact KSS. For this reason, the lift is -400 is in contact with the strip switch and the separator pivot is fully up. It operates only when the temperature is not elevated.

When the separator pivot is raised sufficiently, contact KPU opens and the strips Movement of the seven-point regulator from the switch opens the circuit and stops further operation. .

Relay R-KRL also works in the control to lower the separator mechanism. . This control part is operated by three parallel contacts, two normally closed and one normally open. , the cylinder 400H of FIG. 3 is controlled. Contact KRL, which is normally open, is acts on the cylinder 400H while it is rising. Parallel contact KLD-A is also The shunt contact KPOR provides a signal path when the load is not lowered sufficiently. Provides a signal path in case finger 402 is not fully retracted.

The next automatic operation is front stop 303, separator play) 401, and Regarding the tear-off finger 402. It was noted in connection with the rise in Similarly, one of the conditions is that the front stop is contacted by the block mark 8 detector. This means that it must rise sufficiently to close KSIi'U. . For proper stripping operations, the front stop must be in the position shown in Figure 2. must be lowered to This operation is based on the hydraulic series of the first control branch in FIG. This is performed by the printer 303H. This control consists of normally open contacts KSKP and KB. Contains C'I'. It also includes normally closed contacts KPU and KL3. child Therefore, the front stop is blocked when the stack is in the stripping position. It will be lowered through the action of contact KSKP by the signal detected at mark 9. . Associated contact KBCT is also closed after an appropriate delay interval, and stop 303 is lowered. There should be no sheet stack on the combo box 304 that would interfere with the above. Contact KP U and KL3 indicate that the separator 400 does not rise sufficiently and the detection position 13 is not detected. It remains closed unless there is a known sheet bundle.

When the stop 303 is sufficiently lowered, this condition is detected by the detector block marked 10. relay R451i of the second control branch as long as contact KNOP remains closed. ’D is energized. Relay R-KS]li″D is a contact KSF″D and a normally closed contact. The branch circuit for block mark 10 containing point KPOE maintains the operating state. Ru. When the stripping arm extends, the front stop lowering signal is terminated. centre While the four-to-stop drop signal is being generated, the third no-ranch circuit in FIG. It is operated by a contact 5KFD that acts directly on the hydraulic cylinder 402H.

The hydraulic cylinder moves the stripping finger 402 to the sheet bundle in FIG. The sheet bundle is engaged and advanced toward the sheet bundle conveyor 304. Nananozo δ The letter plate 401 is connected to the block as shown in the fourth control branch of FIG. By contacting the detector of the lock mark 23 in advance, it is extended upward in advance.

A momentary contact is sufficient to continue the signal by relay R-KSC. Branching time In addition to the contact KSG, the stripping cylinder 402 is normally closed and the conductor 402 is fully extended. This is because it includes a contact KPOE that opens only when this occurs. Ce lurie play Once the torque has risen sufficiently, the relay is activated, as shown in the fourth control branch of FIG. - Activate R-KSPU.

When the stripping cylinder is fully extended, the circuit arrangement for relay R-KSF"D The circuit for relay R-KSC is opened. Power is removed from the stripping cylinder. Once removed, the stripping cylinder begins to retract and the separator plate 401 opens. released. This is because the retraction of the stripping cylinder does not move the sheet bundle B1 backward. Prevent proper triggering.

As mentioned above, the sheet bundle B1 moves to the position P2, reaches the knee part K, and moves onto the descending conveyor. 501d or simply towards the be thrown out. The control branch for the descending conveyor is the branch shown in Figure 4D. This is the first brunch of the lunch. This branch is a descending conveyor cylinder 501h. The descending conveyor 501d is omitted from the system 10. However, when it exists, the height of the inclined support member 501 as shown in FIG. It is desirable to maintain a receiving position in the upper position. Detector with block mark 26 When a load on the descending conveyor is detected by activation of a photoconductive cell, a relay is activated. Since R-KDC is energized by photoconductive cell D26, the first two blocks in FIG. Lunch becomes operational. This closes the normally open contact KDC of the first branch, The cylinder 501h is lowered to the same height as the inclined back rest 501. This effect Detected by the detector 16 of the lock mark 16, the relay R of the third nozzle in FIG. 4D - Generate signals on KS3-A and R453-B. This is further shown in Figure 4D. Acts on branch relay R-KSS and side guides 502-1 and 502-2 (not visible in Figure 3).

When the position of the sheet bundle B1 is adjusted, the upsetting and feeding along the feed table 600 are performed. It is now possible to remove it. The circuitry for these operations is shown in the control branch of Figure 4E. is shown. In the first branch, the detector with block mark 15 is the switch breaker. It includes a relay R-KAR which is energized when activated by. Relay R-K AR acts on the transfer contact KAR of the second branch. pre-charged container The charge is impressed on relay R-KARM by the transmission action of contact KAR. added. Following actuation of the regulating cylinder, the timer brake shown in Figure 4E A delay signal is generated on the inch and extend branches to actuate the upset arm.

The bushing cylinder is actuated by its control branch and its actuation is Monitored by detectors 18 and 19.

Further, the detector of the block mark 20 detects that the sheet bundle B1 is pushed from the position P6. It indicates when the end of the sending conveyor 600 has been exceeded. various relays and the operation of the contacts is as detailed in the following table showing the contacts and their functions: . Relays communicating with contacts are marked with an "R" symbol.
