Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. Components common to the following embodiments (including modified examples) may be assigned the same reference numerals as those described above, and description thereof may be omitted. In addition, when referring to the shape, positional relationship, etc. of components, etc., unless otherwise specified or in principle clearly considered otherwise, etc. that are substantially similar or similar to the shape, etc. shall include In addition, terms such as attachment, connection, and fixation include both cases of direct action and cases of indirect action via other members.

FIG. 1 is a block diagram showing a counting device according to one embodiment of the present application. The counting device 1 includes a carrying-in device 2 for carrying a plurality of works into the counting device 1, an elevating device for lifting the carried-in works for counting, a counting and dividing device 6 for counting and sending out the rising works, and a sending device. It comprises a carry-out device 7 for carrying out the counted workpieces from the counting device 1, and a control panel 8 electrically connected to these to control the operation.

The workpieces to be counted by the counting device 1 are plate-like workpieces, which are particularly thin in relation to the planar area, and the efficiency of manual counting work is poor, so automation is desirable. Although a corrugated cardboard sheet will be described below as a typical example, it is not limited to this, and the counting device 1 of the present application can be widely applied as long as it has a flat surface and is thick.

In order to lift and convey the workpieces carried in by the carry-in device 2 for counting, one lifting device may be used, or two or more lifting devices may be used. As an example, the counting device 1 includes a lifting table device 3 (hereinafter also referred to as “first lifting device”), a first lifting ledge device 4 (hereinafter also referred to as “second lifting device”), and a second lifting ledge device 5 (hereinafter referred to as “second lifting device”). (also referred to as a "third lifting device"). Although the details will be described later, the counting device 1 can shorten the cycle time and count at high speed by providing two or more lifting devices.

FIG. 2 is a conceptual diagram showing an example of a counting device. FIG. 3 is a front view showing a specific example of the counting device. In the illustration, X indicates the front-back direction (horizontal direction) (+X is rearward, -X is front), Y indicates the vertical direction (+Y is upward, -Y is downward) (same in FIG. 3 and below) ). Note that Z in the drawings described later indicates the depth direction perpendicular to the X and Y directions (+Z is the back direction, -Z is the front direction).

The counting device 1 carries in batches a plurality of workpieces W stacked in the vertical direction in a rectangular parallelepiped shape by a loading device 2 . The carry-in device 2 receives a batch of a plurality of workpieces W stacked in a rectangular parallelepiped form from the rear upstream process, and transfers them batch by batch to the forward lifting device at a predetermined position and at a predetermined timing. Preferably, the carrying-in device 2 adjusts the position of the work W in the depth direction so that the center line of the work W coincides with the center line of the counting and dividing device 6, and delivers the work W to the lifting device. The carry-in device 2 is, for example, a stationary conveyor such as a belt conveyor or a roller conveyor. The carrying-in device 2 may be a freely movable device such as an unmanned guided vehicle.

The counting device 1 includes a counting space F for counting a plurality of works W, and an elevation space E for carrying the plurality of works W loaded in the counting space F upwardly.

A batch of workpieces W that have been carried in are lifted vertically in the rising space E by the lifting device in a horizontal state, counted and divided in the counting space F, and then carried out horizontally forward by the carrying-out device 7 .

To facilitate counting, it is conceivable to handle the workpieces W at an angle (eg, tilt the batch forward), but this takes extra time to tilt and to return from an angle to a horizontal position. Since the counting device 1 treats the work W horizontally and moves the work W up and down and counts it vertically and horizontally, it does not take extra time and can count at high speed. In addition, if the workpiece W is tilted and processed, the load is applied to the end portion of the workpiece W, so the workpiece W is likely to be damaged. Since the counting device 1 handles the workpiece W horizontally, it is possible to avoid applying an extra load to the edge of the workpiece W. - 特許庁

Further, the angle regulating body 621 is tilted horizontally, and the steps are eliminated by the aligning body 641 to align the stepped work group Wa (step S125) ((3) in FIG. 9).

(4) Next, the counting and dividing device 6 moves the aligning body 641 upward and retracts it, and pushes the work group Wa forward with the pushing body 631 (step S126) ((4) in FIG. 9).

(5) Next, the counting and dividing device 6 moves the extrusion body 631 to the standby position, and moves the molded body 611 to the standby position (step S127) ((5) in FIG. 9). The work group Wa sent out is unloaded by the unloading device 7 .

FIG. 10 is a diagram for explaining in detail the configuration relating to counting of the counting division device.

First, the modeled body 611 will be described. The surface (contact surface) of the modeled body 611 that contacts the work W is a quarter of the front lower portion of the outer peripheral surface. Which position within the above range of the modeled body 611 is to be brought into contact with the work W, that is, the position of the modeled body 611 in the front-rear direction and the vertical direction depends on the thickness of the work W, the deviation width G for accurate counting, the rotational torque, etc. can be adjusted accordingly.

The modeled body 611 comes into contact with the work W only at the rear end of the upper surface of the work W, the upper corner of the rear end, and the rear end surface. It is preferable to adjust the coefficient of friction of For example, when it is necessary to reduce the load on the workpiece W, the frictional resistance of the outer peripheral surface of the modeled body 611 is reduced by coating, polishing, or the like. Conversely, when it is necessary to increase the load, the modeled body 611 is provided with a frictional resistance that does not damage the work W. As an example, unevenness is formed on the contact surface to increase the coefficient of friction. Processing, etc. can be considered.

When hitting the modeled body 611, the ascending work W slides forward with respect to the adjacent lower stage work W, and hits and stops at the angle regulation body 621 waiting in front. Therefore, the deviation width G becomes uniform. It can also be said that the angle regulating body 621 guides the modeling by the modeled body 611 . The ascending work W contacts the modeled body 611 one after another, creating step-like steps one after another, and then ascends as it is. of work groups are born. The regulation angle α, which is the angle at which the angle regulation body 621 is tilted from the horizontal, can be arbitrarily adjusted according to the type of work W, particularly according to the thickness of the work W. For example, it can be adjusted to 15 degrees to 45 degrees. be. By making the regulation angle α adjustable, the displacement width G is increased from a thick workpiece W to a thin workpiece W, thereby improving the reading accuracy of the extruded body 631 . A deviation width G of, for example, 5 mm to 45 mm can be secured.

The extruding body 631 detects a step (height difference between upper surfaces) H between the workpieces W formed in a step shape by a detection device 6312 provided near the lower end, and counts the number of steps, which is the number of steps, to detect the workpiece W. Count. The detection device 6312 is, for example, a laser displacement sensor, and is installed so that its optical axis is parallel to the rear end surface of the work W. As shown in FIG.

There is a counting device that captures an image of the end face of a work W, for example, the end face of a cardboard sheet, analyzes the image information, and counts the number of sheets. Recognition failure is likely to occur, and the possibility of counting errors increases. Accuracy can be improved by using advanced AI technology, but it will be expensive.

The counting device 1 is formed in a stepped shape, continuously measures the distance to the stepped portion, and detects the number of workpieces W based on the number of steps where the distance changes abruptly.

The pushing body 631 can move horizontally and vertically, and the step can be read at a short distance. For example, a thin work W having a thickness of about 1.5 mm can be read with high accuracy by being read closer, but the extrusion body 631 can be moved horizontally and vertically to approach the optimum position, so that the work can be read with high accuracy.

The extruded bodies 631 may be counted after the modeling has progressed to a certain extent, or as long as at least one step is created, the counting can be performed almost simultaneously with the modeling.

FIG. 11 is a diagram showing Modification 1 of the counting division device. In this example, the counting and dividing device 6 further includes a rear restricting portion 66 that is arranged to face the angle restricting body 621 and maintains the level difference. The rear restricting portion 66 has a rear restricting body 661 and a rotation mechanism 662 that rotates the rear restricting body 661 . The rear restricting body 661 is, for example, a plate-like member. Instead of providing the rotation mechanism 662, the rear regulating body 661 may be made elastic so that the angle can be changed by deformation.

The rear regulating body 661 is spaced from the angle regulating body 621 by the front-rear width I of the work W or at least the front-rear width I of the work W on the opposite side of the angle regulating body 621 across the work W formed in a stepped shape. It is adjusted to be parallel to the angle restricting body 621 (inclined at the same angle as the restricting angle α) with a space therebetween. Preferably, the rear regulating body 661 has a surface parallel to the surface of the angle regulating body 621 in contact with the workpiece W. As a result, even if there is a workpiece W that is sent out by the modeled body 611 and hits the angle restricting body 621 and rebounds, the rear restricting body 661 restricts it from behind, so that the level difference is maintained.

FIG. 12 is a diagram showing Modification 2 of the counting division device. In this example, the counting and dividing device 6 further includes a lower work movement prevention unit 65 that prevents the work W below the work group W from moving. The lower work movement prevention unit 65 has a movement prevention body 651 and a vertical movement mechanism (not shown).

(1) After stopping the rotation of the modeled body 611 to deliver the work group Wa (that is, after stopping the modeling operation that causes the step) (between steps S123 and S124 in FIG. 8). can prevent the work W from moving by pressing the work W below the displaced lowermost work W (the obliquely shaded work indicated by the arrow in the drawing) with the shaped body 611 ((1) in FIG. 12). .

(2) The movement preventive body 651 rises until the modeled body 611 retreats backward, and the lowermost end work (black-painted work) W of the work group Wa (the oblique line portion work indicated by the arrow in the drawing) is adjacent to the work W. In front of W, the adjacent work W below the work group Wa is prevented from moving forward ((2) in FIG. 12).

(3) When the molded body 611 retreats backward, the pushing body 631 descends to the rear of the lowermost work (black-painted work) W of the work group Wa, and the work W (the arrow in the drawing) below the lowermost work W ) is pressed ((3) in FIG. 12). Thereafter, the pushing body 631 pushes and delivers the work group Wa forward.

In this way, the movement prevention member 651 can prevent the work W below the work group Wa to be delivered among the stepped works from being taken out when the work group Wa is delivered.

13A and 13B are diagrams for explaining the arrangement of the counting and dividing devices. FIG. The counting and dividing device 6 preferably counts the workpieces W, aligns them, and then divides and delivers them.

The workpiece group Wa has a stepped shape when viewed from the rear end side, and a parallelogram shape when viewed from the front as a whole. If an attempt is made to push the work group Wa forward as it is, it will inevitably be pushed out from the rear lower end, but the weight of the work W is also added, and there is a risk that the end face of the work W at the lower end will be damaged. Further, it is necessary to return the angle regulating body 621 horizontally, and if there is no front support, the work group Wa may collapse if force is applied from the rear while maintaining the parallelogram shape. Therefore, the counting and dividing device 6 is provided with the aligning unit 64, and the aligning body 641 eliminates the step between the adjacent works W, and aligns the front ends and the rear ends of the works W in the front-rear direction to align them in a rectangular parallelepiped shape.

(1) The aligning body 641 moves from the front to the rear to align the work group Wa ((1) in FIG. 13). As described above, the aligning body 641 has a comb-teeth shape downward and can pass between the angle regulating bodies 621. Therefore, the work group Wa can be moved without tilting the angle regulating bodies 621 horizontally. can be aligned.

(2) The aligning body 641 moves from the front to the rear, makes contact with the uppermost end work W of the work group Wa in order from the frontmost end, and pushes it backward to eliminate the step between the adjacent works (Fig. 13). of (2)). The pushed-in work group Wa abuts the rear pusher 631 at its rear end. By aligning the workpieces W from the front in this way, since the workpieces W are pushed in from the lighter side, the load applied to the workpieces W is smaller than when the workpieces are pushed out from the rear lower end. Further, by aligning the end faces in stages, the end face pressure receiving area in contact with the aligning body 641 is gradually increased, the load on the end face of the work W is reduced, and damage to the end face of the work W can be prevented.

(3) Alignment body 641 rises when alignment is completed. Also, the angle regulating body 621 is laid down horizontally. ((3) in FIG. 13).

(4) When the aligning body 641 moves (retracts) above the uppermost work of the work group Wa, the pushing body 631 pushes and delivers the work group Wa forward ((4) in FIG. 13). Since the end faces of the work group Wa are aligned, the pressure receiving area is increased, the load on the end face of the work W is reduced, and the work W can be conveyed without damage.

14 and 15 are diagrams showing Modification 3 of the counting division device. In this example, the pushing body 631 is conveyed by following or lifting the work group Wa. Furthermore, the aligning body 641 may prevent the work group Wa from collapsing during transportation.

The pushing body 631 further has a claw portion 6313 provided at the lower end. The claw portion 6313 is provided at the lower end of the pushing body 631 so as to extend horizontally from the rear end to the front end. The front end of the claw portion 6313 gradually decreases in thickness to form a ∠ shape (see FIG. 15). The pushing body 631 inserts the claw portion 6313 below the work group Wa, puts the rear end of the work group Wa on the claw portion 6313, and lifts the claw portion 6313 by several mm so that the lower surface of the claw portion 6313 does not contact the remaining work W. Carry forward.

The aligning body 641 may be moved in synchronism with the forward movement of the work group Wa instead of retracting upward to prevent the work group Wa from collapsing.

As shown in FIG. 15, the detection device 6312 of the extruded body 631 may perform an air purge by ejecting air from a nozzle 6314 in order to remove paper dust and water vapor.

FIG. 16 is a diagram showing Modification 4 of the counting division device. In this example, the modeling section 61 of the counting and dividing device 6 further has a downward workpiece movement preventing section 614 . By providing a lower work movement prevention part (pressure plate) 614 in the modeling unit 61, even if the modeled body 611 retreats backward, the lower work movement prevention part 614 is used to hold down the work W below the work group Wa. movement can be prevented.

As shown in the figure, when the work group Wa is placed on the claw portion 6313 of the pushing body 631 and lifted and conveyed forward, the angle regulating body 621 is set at an angle smaller than the regulating angle when forming the step (movement prevention angle ) to hold the work group Wa pushed out from the pushing body 631, and separate it from the remaining works W to prevent the work W below from moving. The movement prevention angle is adjusted within a range that does not damage the front end of the work group Wa.

FIG. 17 is a diagram showing Modification 5 of the counting division device. In this example, the modeled body 611 is configured not by a rotating body but by a pusher mechanism 615 that reciprocates an inclined plate. The angle of the inclined plate of the pusher mechanism 615 can be adjusted automatically or manually. By further vibrating the inclined plate, the frictional force between the works W may be reduced to reduce the pushing force. By blowing air between the works W, an air layer may be provided between the works W to reduce the frictional force between the works W, thereby reducing the pushing force.

FIG. 18 is a diagram showing Modification 6 of the counting division device. In this example, the modeled body 611 is composed of an inclined belt conveyor mechanism 616 instead of a rotating body. The angle of the belt conveyor that contacts the workpiece W of the belt conveyor mechanism 616 can be adjusted automatically or manually. The belt conveyor is horizontally movable, and by moving horizontally, it is possible to adjust the load at the time of pushing out and the amount of shift of the work W to the front. By vibrating the belt conveyor, the frictional force between the works W may be reduced to reduce the pushing force.

FIG. 27 is a diagram showing Modification 7 of the counting division device. In this example, the counting and dividing device 6 further includes a pressing portion 67 that applies a load to the upper surface of at least the uppermost workpiece W. As shown in FIG. The pressing portion 67 has a pressing body 671 that contacts the upper surface of the uppermost workpiece W, and a suspending portion 672 for suspending the pressing body 671 . The holding portion 67 further has a support portion (not shown) that supports the suspension portion 672 . The presser body 671 rises as the lifting device rises.

In other words, in this example, the counting and dividing device 6 horizontally shifts the workpieces W raised by the lifting device in the front-rear direction perpendicular to the up-down direction, which is the stacking direction, to create a stepped difference between the adjacent workpieces W. A modeling section 61 having a modeling body 611, an angle regulation body 621 facing the modeling body 611, and an angle regulation section 62 that adjustably regulates a shift width, which is a distance by which the workpiece W shifts, and is suspended from above. A pressing body 67 having a pressing body 671 that applies a load to the upper surface of the uppermost work W of the rising work W, and a detection device that detects the step and counts the work W. and an extrusion section 63 having an extrusion body 631 capable of horizontal and vertical movement.

When the counting and dividing device 6 forms a plurality of works W in a stepped manner using the forming body 611, there is a risk that the works W may fly. Here, the work W flying means that the work W moves forward and rides on the angle regulating body 621 , or bounces back from the angle regulating body 621 and rides on the modeled body 611 . In particular, the uppermost work W is likely to fly because there is no work W above it and it does not receive the load of the work W above it.

Therefore, in this example, the above-described problem is solved by further providing a pressing portion 67 and applying a load to at least the uppermost work W so that it can be shifted but does not fly.

A pressing body 671 of the pressing portion 67 comes into contact with the upper surface of the uppermost work W and rises as the uppermost work W rises. For example, in the drawing, the holding member 671, which was initially positioned as indicated by the dashed line, rises to the position indicated by the solid line as the uppermost workpiece W rises. That is, a load is applied by the pressing member 671 also when the workpiece W below is shaped. Therefore, preferably, the load of the pressing member 671 is reduced as the work W on the uppermost stage rises. After the uppermost workpiece W has been shaped, the pressing body 671 is separated from the uppermost workpiece W and retracted upward. For example, the presser body 671 is designed to leave the uppermost workpiece W and retreat upward after a predetermined time has elapsed since the start of modeling. The pressing part 67 includes a vertical movement mechanism in which a support part (not shown) vertically moves the pressing body 671 and the suspension part 672, and the pressing body 671 is retracted upward by the vertical movement mechanism. . The pressing part 67 may be configured so that the pressing body 671 does not retract. In this case, the pressing body 671 can be raised to at least the maximum height at which the uppermost workpiece W can be raised.

The pressing body 671 is, for example, a rotating body having a rotating shaft extending parallel to the depth direction. The pressing body 671 is configured by a roller, for example. More specifically, the pressing body 671 is composed of, for example, a free roller, and even if the uppermost workpiece W moves forward, the pressing body 671 stays in place while rotating and does not move back and forth. The presser body 671 is composed of, for example, a driving roller provided with a driving portion (for example, a roller driven by a driving portion such as a motor) that rotates according to the forward movement of the uppermost work W during molding. good too. As an example, the pressing body 671 may be configured by a wheel-shaped rotating body. Needless to say, the holding member 671 may be configured to move forward together with the uppermost workpiece W.

The suspension part 672 has one end to which the pressing body 671 is attached and the other end to which the main frame 10 is connected via a support part (not shown). The suspension part 672 is not particularly limited, but is preferably extendable, so that the suspension part shrinks as the pressing body 671 rises.

The suspending portion 672 includes, for example, a coil spring, such as a compression coil spring, and the pressing member 671 is at the initial position indicated by the dashed line in the free length. The hanging part 672 is configured including an air cylinder, for example, and the pressing body 671 is connected to the lower end of the piston rod. As an example, the suspension part 672 includes a leaf spring, and when the leaf spring is bent, the pressing body 671 is pulled up.

The pressing part 67 is not limited to the above configuration as long as it applies a load to the upper surface of the uppermost work W so that the work W does not fly off, although the work W can be formed in a stepped shape (shifted). For example, the pressing member 671 of the pressing portion 67 may be a plate-like body having a low friction coefficient on the lower surface instead of the rotating body. The pressing portion 67 may be a leaf spring arranged so that the pressing body 671 is in contact with the upper surface of the work W on the uppermost stage. The presser body 671, which is a leaf spring, is in the lower end position indicated by the broken line in the drawing in the initial state, and when the uppermost workpiece W rises, it is elastically deformed and bends upward. The pressing part 67 is attached to the lower end of the piston rod of the suspension part 672 when the pressing part 671 is a leaf spring and the suspension part 672 is an air cylinder. The pressing portion 67 may be configured such that the pressing portion 671, which is a leaf spring, is directly attached to the vertical movement mechanism of the supporting portion (not shown) without having the suspension portion 672. FIG.

The pressing portion 67 stands by while the pressing body 671 is at the initial position indicated by the dashed line in the drawing. Alternatively, the holding part 67 suspends the holding body 671 to the initial position before the workpiece W enters the counting space F described above. This may be done at the same time as the steps S121 and S122 described above, or before or after them (see FIG. 8). Then, the pressing member 671 comes into contact with the upper surface of the uppermost work W entering the counting space F and applies a load, and the modeling body 611 performs modeling with the load applied. That is, in the step of forming a stair-like step, a load is applied to the upper surface of the uppermost workpiece W rising by the pressing member 671 suspended from above.

Next, the lifting device will be described. In addition, although a specific example is shown below, these are only examples and this application is not limited to these. The lifting device may be of a mechanism such as a hydraulic lifter that lifts from the bottom, or of a mechanism that suspends from the top with a chain or the like.

A part or all of the plurality of belt conveyors 311 are synchronously rotated by a rotation drive mechanism (not shown) included in the loading table 31 . The loading table 31 is, for example, an intermediate drive type in which a rotation drive mechanism is arranged in the intermediate portion.

The stacking table 31 can be moved vertically by a vertical movement mechanism 32 . A pair of vertical movement mechanisms 32 are provided on the front side and the back side in line symmetry. Here, the vertical movement mechanism 32 on the front side will be described as an example. As an example, the vertical movement mechanism 32 includes a frame portion 320, a motor 321 fixed above the frame portion 320, a sprocket 322 disposed within the frame portion 320, sprockets 323 disposed on both sides of the sprocket 322, It has a sprocket 324 and a chain 325 whose ends are fixed to the ceiling of the frame part 320 and whose ends are wound around the sprockets 322 , 323 and 324 . The sprocket 322 is fixed at a position near the ceiling of the frame portion 320 , the support portion 310 of the loading table 31 is connected to the sprocket 323 , and the counterweight is connected to the sprocket 324 . By rotating the sprocket 322 by the motor 321 and driving the chain 325, the belt conveyor 311 can be lifted from the standby position and lowered to the standby position as indicated by the broken line in the drawing.

The plurality of loading bars 411 are connected at their front ends by the support portion 410 and have free ends at their rear ends. The stacking bar 411 has a width in the depth direction narrower than a predetermined interval between the belt conveyors 311 and can be inserted between the belt conveyors 311 . The number of loading bars 411 is preferably equal to the number of belt conveyors 311±1 so that the center of the work does not shift when the work is delivered. The support portion 410 has a plate-like portion extending in the depth direction connecting the front ends of the plurality of loading bars 411, and a pair of rod-like portions provided on the plate-like portion and extending vertically.

FIG. 22 is a flow chart showing an example of the operation of the lifting device. Figures 23A to 23F are diagrams illustrating transport by three lifting devices. For convenience of explanation, first, an example of transportation by three elevators will be explained.

Each lifting device stands by in the state shown in FIG. That is, the lifting table device 3 waits with the loading surface of the loading table 31 positioned in the carry-in area A, and the first lifting ledge device 4 moves the loading surface of the first loading ledge 41 forward of the lifting space E to the first delivery. The second lifting ledge device 5 waits at the same height as the area B, and the second lifting ledge device 5 waits at the rear of the ascending space E with the loading surface of the second loading ledge 51 at the same height as the second transfer area C.

(1) First, the loading table 31 loads the batch work W from the loading device 2 in the loading area A (step S101) (FIG. 23A).

(2) The loading table 31 moves up to the first delivery area B (step S102) and waits in the first delivery area B (step S103) (FIG. 23B).

(3) Then, the first loading ledge 41 receives the batch work W from the loading table 31 while moving horizontally from the front to enter the first transfer area B in the ascending space E (step S105). More specifically, a comb-shaped loading bar 411 directed toward the rear of the first loading ledge 41 is inserted between the belt conveyors 311 of the loading table 31 to receive the works W of this batch (FIG. 23C).

(4) After delivery, if it is the next counting processing timing (Yes in step S106), the first loading ledge 41 lifts the workpiece W into the counting space F and carries it in, and if it is not the next counting processing timing ( No in step S106), wait, and carry in at the next counting processing timing (step S107). In the meantime, the loading table 31 descends to the carry-in area A (step S104) (FIG. 23D).

If there is a space for receiving the next batch work W in the ascending space E, the loading table 31 loads the next batch work W from the carry-in device 2 (step S101) (FIG. 23E).

(5) When the first loading ledge 41 rises to the second delivery area C (Yes in step S108), the second loading ledge 51 enters the rising space E while moving horizontally, and picks up the remaining works W of this batch. Receive (step S111) (FIG. 23E). While the work W has not been lifted to the second delivery area C (No in step S108), the first loading ledge 41 lifts and carries the work W into the counting space F at a predetermined timing.

In the second delivery area C, the first loading ledge 41 retreats while delivering the remaining works W of this batch to the second loading ledge 51 (retreats forward from the ascending space E) (step S109) (FIG. 23E). . The first loading ledge 41 stands by, the loading bar 511 of the second loading ledge 51 is inserted between the loading bars 411 of the first loading ledge 41 to receive the workpiece W, and then the first loading ledge is retracted. Delivery may take place at

(6) After delivery, if it is the next counting processing timing (Yes in step S112), the second loading ledge 51 lifts the workpiece W into the counting space F and carries it in. If it is not the next counting processing timing ( No in step S112), wait, and lift and carry in at the next counting processing timing (step S113). The first loading ledge 41 descends to the height of the first delivery area B (step S110) (FIG. 23F).

(7) When the second loading ledge 51 ascends to the end area D (Yes in step S114), it retreats (withdraws rearward from the ascending space E) (step S115) and descends to the height of the second delivery area C. (step S116). While the work W has not been lifted to the end area D (No in step S114), the second loading ledge 51 lifts and carries the work W into the counting space F at a predetermined timing.

Note that the second loading ledge 51 has a comb-like shape toward the front, and the bar-shaped portion of the supporting portion is also spaced apart, so even if the modeled body 611 and the modeled body 611 overlap each other in the front-rear direction, they interfere with each other. can operate without

As described above, the main batch work W may be lifted from the carry-in area A to the end area D by one lifting device of the lifting table device 3 . In this case, the time required for the loading table 31 to return from the end area D to the carry-in area A after the batch work W is processed by the counting and dividing device 6 is added to the cycle time. The cycle time is the time required to process one batch of works W (the time required from the start of carrying one batch of works W into the counting device 1 to the start of carrying in the next batch of works W).

Alternatively, the batch work W may be lifted from the carry-in area A to the end area D by two lifting devices, the lifting table device 3 and the first lifting ledge device 4 . FIG. 24 is a flow chart showing an example of transportation by two elevators.

First, the loading table 31 loads the batch work W from the loading device 2 in the loading area A (step S101). The loading table 31 moves up to the first delivery area B (step S102) and waits in the first delivery area B (step S103).

Then, the first loading ledge 41 receives the batch work W from the loading table 31 while moving horizontally from the front to enter the first transfer area B in the ascending space E (step S105).

After delivery, if it is the next counting processing timing (Yes in step S106), the first loading ledge 41 lifts the workpiece W into the counting space F and carries it in. If it is not the next counting processing timing (step S106). No), stand by, and carry in at the next counting processing timing (step S107).

After delivery, the loading table 31 descends to the carry-in area A (step S104). If the space for receiving the next batch work W is available in the ascending space E, the loading table 31 loads the next batch work W from the carrying-in device 2 (step S101).

When the first loading ledge 41 ascends to the end area D (Yes in step S117), it retreats (retreats forward from the ascending space E) (step S118) and descends to the height of the first delivery area B (step S119). While the work W has not been lifted to the end area D (No in step S117), the first loading ledge 41 lifts and carries the work W into the counting space F at a predetermined timing.

In this example, the first lifting ledge device 4 is configured so that the first loading ledge 41 can be lifted up to the end area D. As shown in FIG.

As in this example, when two lifting devices are used, the loading table 31 can return to the carry-in area A while the first loading ledge 41 is carrying up and conveying, so that the cycle time can be shortened. In addition, by using two lifting devices, the loading table 31 can carry in the next batch work W even while the work W is being raised, if there is a space for receiving the next batch work W in the rising space E. Therefore, the cycle time can be further shortened.

Furthermore, as in the above example, if three lifting devices are used, the first loading ledge 41 returns to the initial standby position and leaves the loading table 31 while the second loading ledge 51 is carrying the workpiece W upward. Being ready to receive the next batch of work W further reduces cycle time. That is, by using three lifting devices, it is possible to change the lifting devices and carry in the work W while the counting and dividing device 6 is performing processing, so that a further increase in speed can be realized.

25A and 25B are diagrams for explaining modification 1 of the lifting device. The counting device 1 loads and counts the works W for each batch, and unloads the counted works W for each work group Wa, but the number of the works W remaining at the end of one batch may be insufficient for one group. . In the following, the work W that is insufficient for one group is referred to as a surplus work, and the configuration related to the process (also referred to as "relaying process") will be described.

When the second loading ledge 51 rises to the end area D, surplus workpieces W that are counted (or some or all of which are not yet counted) remain on the second loading ledge 51 . At this time, the first loading ledge 41 has already received the next batch work W from the loading table 31 and is on standby. In the above example, the first loading ledge 41 waits until the second loading ledge 51 leaves the rising space E, but in this example, at the timing when it is determined that the surplus work W is generated, or after that. As shown in FIG. 25A , the first loading ledge 41 rises to approach the second loading ledge 51 .

As shown in FIG. 25B, when the first stacking ledge 41 rises to a predetermined position and waits at that position, the second stacking ledge 51 moves out of the rising space E and the uppermost work W of the next batch work W is moved to the lower end surface. surplus work W is handed over to the first loading ledge 41 so as not to come into contact with the . On the other hand, the first loading ledge 41 waiting below receives the surplus work W so as to be placed on the next batch work W. The second loading ledge 51 descends to the height of the second transfer area C after leaving the ascending space E.

As in the present example, it is possible to easily cope with the case where surplus works W are generated by carrying them upward using three elevating devices.

26A to 26C are diagrams showing modification 2 of the lifting device. The lowermost workpiece W of the workpieces W stacked in a rectangular parallelepiped shape in one batch may be collected and discarded because it is contaminated. Hereinafter, such one batch of lowermost works W will be referred to as a waste work V. As shown in FIG. Normally, the waste work V is collected when the lifting device descends to the carry-in area A. In this case, the time required for the descent of the lifting device and the collection time for the waste work are added to the cycle time. This example includes three lifting devices and further includes a configuration for collecting waste works, thereby eliminating such additional time from the cycle time.

The counting device 1 includes a waste work recovery section. As an example, the waste work recovery section includes a waste work release section 91 that releases the waste work V from the ascending space E, and a waste work take-up section 92 that takes in the released waste work V. FIG. Discarded works V are discharged when the remaining works W of this batch are transferred between the first loading ledge 41 and the second loading ledge 51 in the second delivery area C. 2 It is installed on the main frame on the same side as the first loading ledge 41 advance side in the vicinity of the delivery area C.

Although not particularly limited, the waste work take-up unit 92 is preferably located between the first delivery area B and the second delivery area C at a position further away from the rising space E on the same side as the first lifting ledge device 4 installation side. is installed at a height of The waste work take-up unit 92 is provided with, for example, a vacuum suction pad on its lower surface so that it can move horizontally. A collection container is installed below the waste work take-up unit 92 .

As shown in FIG. 26A , in the work delivery in the second delivery area C, the waste work discharging section 91 causes the waste work V to stay on the first loading ledge 41 when the first loading ledge 41 leaves the ascending space E. Only the waste work V is discharged from the rising space E in this manner. As an example, the waste work discharge unit 91 is installed at a position higher than the second delivery area C and has a vertically movable plate-like portion. front end surface) to dam up the work W above the waste work V including the adjacent work W. As a result, the first loading ledge 41 leaves the ascending space E while delivering the remaining workpieces W of this batch to the second loading ledge 51 except for the discarded workpieces V, and the second loading ledge 51 enters the ascending space E. while receiving the remaining works W of this batch except for the discarded works V.

As an example, although not shown, the waste work collecting section has a holding section that makes it easy to hold the waste work V on the loading surface of the first loading ledge 41 instead of or together with the waste work releasing section 91. It also has a pick-up portion that facilitates picking up the plurality of works W accumulated on the loading surface of the second loading ledge 51, except for the discarded works V. As shown in FIG. The retaining portion of the first loading ledge 41 is, for example, a portion that increases the coefficient of friction provided on the loading surface to retain the waste work V on the loading surface, or a portion that adsorbs the waste work V to retain the waste work V on the loading surface. is. The take-up portion of the second loading ledge 51 is, for example, a portion that reduces the coefficient of friction and is provided on the loading surface in order to take away the piled works W except for the waste work V. As shown in FIG.

More specifically, for example, the loading surface of the first loading ledge 41 is provided with a plurality of projections and recesses formed by cutting, shot peening, or the like, or a vacuum suction pad, or the like, as the anchor portion. A grooved rubber plate or the like that increases the frictional force by its deformation may be used. Combinations of the above structures may also be used.

As the take-up part, for example, the loading surface of the second loading ledge 51 is processed to be slippery, or a rotating body such as a free roller or a free belt conveyor without a drive mechanism is used. A device that blows air upward to reduce frictional resistance may be used.

As shown in FIG. 26B, the second loading ledge 51 receives the remaining works W of the main batch from the first loading ledge 41 except for the discarded works V, raises them at a predetermined timing, and carries them into the counting and dividing device 6. do. On the other hand, the first loading ledge 41 retains the waste work V on the loading surface, withdraws from the ascending space E, and descends to the take-up height of the waste work take-up unit 92 .

As shown in FIG. 26C , when the loading surface of the first loading ledge 41 descends to the pick-up height of the waste work take-up unit 92 , the waste work take-up unit 92 moves horizontally to the position of the first stacking ledge 41 and the waste work V is picked up, returned to its original position, and the waste work V is dropped into a collection container. After receiving the discarded work V, the first loading ledge 41 descends to the height of the first delivery area.
